Tooling for special tooling / fixtures /
general standard tooling (similar to standard).
Fixture,or Mechanical Fixtures,as its name
implies, is used to clamp the workpiece clamping device (or guide tool).
Die: the device to define the shape and size
of the production object.
The tool: use in mechanical manufacturing
tool basically used for cutting metal materials, so the "tool" is
generally understood as metal cutting tools,like Diamond Tools.
AIDS: generally refers to connect tool and
machine tool.
Instrument: use various devices to store
the production of objects or tools at work or in the warehouse.
Check gauge: equipment inspection in the
production use.
Fixture: manufacturing systems, the word
corresponding to fixture, sometimes work with synonyms, sometimes also refers
to the general fixture, Taiwan / Japanese / Korean electronic enterprises to
use the word. Belongs to the fixture industry A containing fixture, belonging
to a subordinate relationship.
Application:
The fixture is used for machining workpiece
fastening quickly, when the machine tool, workpiece holding device, process
correct relative position. That is to say workholding fixture processing
machinery is an indispensable component in the machine tool technology to
high-speed, efficient, precise, complex, intelligent, environmental protection
direction driven by the fixture technology towards high fine, efficient, module
combination, general economic development. Also called fixture fixture. Broadly
speaking, any process, in the process for rapid, convenient and safe
installation device of the workpiece can be called the fixture. Such as welding
fixture, test fixture, assembly jig, fixture and so on. The fixture is the most
common, often referred to as the fixture. In the processing machine parts, in
order to make the surface of the workpiece to achieve drawing size
requirements, geometry and other surface the mutual position precision, before
processing The workpiece must be installed (location), to (clamp). Application
of machine tool fixture, to ensure the machining accuracy, stable product
quality; to improve labor productivity and reduce costs; improve the working
conditions of workers, to ensure safe production; to expand the scope of
machine tool technology, to achieve a "machine" the positioning
element (usually by the fixture. Determine the correct position of a workpiece
in the fixture), clamping device, tool guide element (to determine the tool and
workpiece relative position or direction guiding tool), indexing device (processing,
so that the workpiece can complete the number of stations in a single setup of
the rotary indexing device and mobile line dividing device two), connecting
element and fixture (jig base) and other components.

The drum-shaped slewing bearing is a product independently developed by our company. Due to its advantages such as high bearing capacity, long lifespan, high efficiency, and hard to break teeth, it was identified as a provincial-level high-tech product in November 2013.
At present, most of the slewing ring gears in China are straight teeth or tapered teeth, and the phenomenon of broken teeth frequently occurs. The middle thickness of the tooth thickness of the drum tooth gear is thin at both ends, allowing greater angular displacement of the gear pair's two axes. The angular displacement value is 3-6 times of the straight teeth, and the angular displacement compensation amount is large, which improves the contact condition when the gear meshes. Can effectively eliminate or reduce the impact of angular displacement, the radial compression force applied to the pinion by the paired pinion is smaller, which reduces the occurrence of broken teeth. The drum tooth slewing ring uses the equal strength theory to design the meshing pair of gears, and determines the unilateral thinning of the gear according to the requirements of the maximum declination displacement and the maximum bearing capacity. In the same specifications, materials, gear module, pressure angle, displacement coefficient and other conditions, the bearing capacity of the drum slewing bearing is more than 15% higher than the straight tooth. Due to the large amount of angular displacement compensation when the gear teeth are meshed, the contact condition of the gear meshing is improved, and the drum gear slewing ring can also effectively reduce the jitter caused by the gear pair in the transmission process.
After tests and customer use verification, because of its special tooth structure, the drum gear slewing bearing has obvious advantages compared with straight teeth, which can improve the phenomenon of broken teeth, increase the bearing capacity of the slewing bearing, and prolong the rotation. Support life.
In July 2015, the company received an export order and the customer requested that the teeth of the slewing bearing product adopt a drum tooth structure. Based on customer requirements and product requirements, the R&D and Design Department has customized new tools and compiled sample processing technologies. It has tracked the production and testing of drum-shaped slewing bearing samples and successfully developed a certain type of drum-shaped slewing bearing samples. The samples were tested by the testing and testing center, and all technical indicators were in compliance with the requirements of the drawings. After successful trial production of prototypes, small batch production was successfully achieved in collaboration with the Precision Division and the Reload Division and various research institutes, and orders were delivered on schedule.
