Abstract

The invention discloses a work fixture for a double-side grinding and polishing machine. The work fixture for the double-side grinding and polishing machine comprises a fixture body (1), wherein the fixture body (1) is disc-shaped; gear slots (2) which are uniformly distributed are formed in the outer edge of the periphery of the fixture body (1) and can be simultaneously engaged with a sun gear and an internal gear ring of the double-side grinding and polishing machine; and hollowed-out workpiece grooves (3) are formed in the fixture body (1), so that the upper surfaces and the lower surfaces of to-be-machined workpieces placed in the workpiece grooves (3) can be ground and polished, and the to-be-machined workpieces can rotate. The shape of the work fixture of the grinding and polishing machine is designed according to the shape of the grinding and polishing machine, and the work fixture can be engaged with the gear of the grinding and polishing machine well during running; and by the work fixture, the to-be-machined workpieces can be mounted rapidly and accurately, the workpiece grooves correspond to the to-be-machined workpieces to ensure that the to-be-machined workpieces cannot move or deviate in a machining process, and therefore, the machining quality of the to-be-machined workpieces meets requirements.

Example Embodiment

[0015] The present invention will be further described below with reference to the drawings and embodiments.
[0016] Such as Figure 1-2 Shown: a tooling fixture for a double-sided grinding and polishing machine, including a fixture body 1, the fixture body 1 is disc-shaped and the outer periphery of the fixture body 1 is provided with uniformly distributed gear grooves 2, gear grooves 2 It can mesh with the sun gear and the inner gear ring of the double-sided grinding and polishing machine at the same time. There is a hollow workpiece groove 3 on the fixture body 1, so that the upper and lower sides of the workpiece to be processed can be ground and polished. And the workpiece to be processed can rotate. In the above tooling fixture, the thickness of the fixture body 1 is greater than the thickness of the workpiece to be processed; the inner contour of the workpiece groove 3 is consistent with the outer contour of the workpiece to be processed; specifically, the shape of the workpiece groove 3 includes a circle, a rectangle, and an ellipse. Shape, triangle, hexagon.
[0017] The tooling fixture of the present invention designs the shape of the tooling fixture according to the shape of the grinding and polishing machine, which can ensure that the tooling fixture can be well meshed with the gear of the grinding and polishing machine; the tooling fixture can quickly and accurately install the workpiece to be processed In the fixed position in the fixture, different shapes of workpieces to be processed correspond to the fixtures of different shapes of workpiece slots 3, the number of workpiece slots 3 can be determined according to the size of the workpiece to be processed, and can be round, rectangular, or oval. , Triangle, hexagon and other shapes, its purpose is to fix the workpiece to be processed, to ensure that the workpiece to be processed will not move or deviate during the processing, so as to meet the requirements of the processing quality of the workpiece to be processed. The fixture makes the workpiece rotate and rotate in the grinding and polishing machine. The upper and lower surfaces of the workpiece to be processed can be uniformly ground at the same time. The movement resistance of the fixture is small. It is not easy to process the workpiece, especially the thin and brittle material. It is damaged, and the production efficiency is evenly ground on both sides. It is suitable for silicon wafers, sapphire substrates and epitaxial wafers in the optical glass industry.
[0018] The above embodiments are only to illustrate the technical ideas of the present invention, and cannot be used to limit the scope of protection of the present invention. Any changes made on the basis of the technical solutions based on the technical ideas proposed by the present invention fall into the protection scope of the present invention. Within; the technology not involved in the present invention can be achieved through the existing technology.
