Description

Technical Field

[0001] This utility model patent belongs to the field of fixture technology, specifically relating to an adsorption-type fixture for germanium processing. Background Technology

[0002] In the manufacturing and processing of germanium products, there are many disc-shaped thin-walled parts. The machining of these parts usually involves using aluminum elastic clamps to hold the outer diameter of the part. When machining in this way, the clamping of the workpiece causes internal stress, which in turn causes deformation of the surface of the machined part. Furthermore, the aluminum elastic clamps, due to their insufficient roundness, can significantly affect the dynamic balance of the machine tool spindle under high-speed rotation.

[0003] To address this challenge, existing technologies have developed a lathe vacuum chuck fixture, as described in Chinese Patent (CN216442031U). This fixture includes a vacuum pump, a connecting pipe connected to one side of the pump, and a movable block connected to the other end of the connecting pipe. A sleeve is threaded onto the surface of the movable block, and a chuck body is movably connected to the surface of the sleeve. A first spring is fixedly connected to the top of the chuck body, with its tip movably connected to the surface of the sleeve. A second spring is fixedly connected to the inside of the chuck body, with its interior movably connected to the surface of the sleeve. A connecting block is fixedly connected to the other end of the sleeve, and a nut body is threaded onto the surface of the connecting block. The top of the nut body is movably connected to the bottom end of the second spring. This device uses negative pressure to fix the workpiece to be processed. However, the inventors discovered the following drawbacks of this device:

[0004] When fixing disc-shaped parts, the device often fails to accurately locate the rotation axis of the thin-walled disc-shaped parts, which greatly affects the machining accuracy of the parts. Although this problem can be solved by making a mold adapted to the parts for auxiliary positioning, such a mold can only be used once and cannot be adapted to parts of other sizes, which undoubtedly increases the processing cost and reduces the processing efficiency.

[0005] Therefore, this paper proposes an adsorption-type fixture for germanium processing. Utility Model Content

[0006] To address the aforementioned problems, this invention provides an adsorption-type clamp for germanium processing that can be adapted to various sizes of disc-shaped thin-walled parts.

[0007] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: an adsorption fixture for germanium processing, comprising an air pump, a pipe, a rotary cylinder, and a fixture body. The rear end of the fixture body is connected to the rotary cylinder and the air pump in sequence through the pipe. The front end of the fixture body is equipped with a suction cup that can use negative pressure to adsorb the surface of a disc-shaped thin-walled part.

[0010] Preferably, the iris positioning mechanism further includes a rotating seat, a platform, a large gear, a frame, a small gear, a rack, and an L-shaped groove.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1 to 4 As shown, the prior art in this embodiment has the following problems: The inventors have found that there is a lathe vacuum chuck tooling fixture in the prior art, such as Chinese Patent (CN216442031U), which fixes the workpiece to be processed by negative pressure. However, the inventors have found that this device also has the following defects: When fixing a disc-shaped part, the device often cannot accurately locate the rotation axis of the disc-shaped thin-walled part, which greatly affects the processing accuracy of the part. Although this problem can be solved by making a mold adapted to the part for auxiliary positioning, such a mold can only be used once and cannot be adapted to parts of other sizes. This undoubtedly increases the processing cost and reduces the processing efficiency.

[0025] Therefore, the inventor provides an adsorption fixture for germanium processing, including an air pump, a pipe, a rotary cylinder, and a fixture body. The rear end of the fixture body is connected to the rotary cylinder and the air pump in sequence through the pipe. The front end of the fixture body is equipped with a suction cup 3 that can use negative pressure to adsorb the surface of a disc-shaped thin-walled part. The front end of the suction cup 3 is detachably equipped with an iris positioning mechanism that can position the rotation axis of the disc-shaped thin-walled part (wherein the air pump, pipe, and rotary cylinder are not shown in the figure).

[0026] Its effects are as follows: the clamping shaft 1 in the device can be easily clamped and locked by the clamping end of the machine tool, the positioning hole 5 can help the axis of the iris positioning mechanism to be aligned with the axis of the clamping shaft 1, the iris positioning mechanism can be adapted to various sizes of disc-shaped thin-walled parts, reducing processing costs and improving production efficiency.

[0027] Furthermore, the fixture body also includes a fixture shaft 1 and a mounting flange 2. The front end of the fixture shaft 1 is provided with a mounting flange 2 for mounting a suction cup 3. The fixture shaft 1 in this structure can facilitate clamping and locking by the clamping end of the machine tool.

[0028] Furthermore, a plurality of suction holes 4 communicating with the inner cavity of the suction cup 3 are provided on the inner side of the front surface of the suction cup 3, and a positioning hole 5 matching the iris positioning mechanism is provided on the outer side of the front surface of the suction cup 3; the positioning hole 5 in this structure can help the axis of the iris positioning mechanism to be aligned with the axis of the clamp shaft 1.

[0029] Furthermore, the iris positioning mechanism also includes a rotating seat 6, a platform 7, a large gear 8, a frame 9, a small gear 10, a rack 11, and an L-shaped groove 12. The rotating seat 6 is rotatably mounted on the front end of the frame 9. The platform 7 is located inside the rotating seat 6, and the large gear 8 is located on the outer side of the platform 7. Three sets of small gears 10 are rotatably mounted on the frame 9. Each set of small gears 10 meshes with the large gear 8 on the side facing the axis of the frame 9. An L-shaped groove 12 facing the axis of the frame 9 is provided on the side of the small gears 10. A rack 11 that meshes with the small gear 10 is slidably mounted in the L-shaped groove 12. When this structure is in use, it can... First, place the disc-shaped thin-walled part on the stage 7 (with the workpiece facing down). Then, rotate the rotating seat 6. The large gear 8 on the stage 7 drives the small gear 10 to slide the rack 11 towards the axis of the frame 9. This causes the rack 11 to push the disc-shaped thin-walled part towards the center of the stage 7 and align the center of the part with the axis of the frame 9. Then, the iris positioning structure is docked onto the suction cup 3. Finally, the air pump is controlled to suck up the disc-shaped thin-walled part, thus achieving the purpose of aligning the center of the part with the axis of the fixture shaft 1. This structure can be adapted to disc-shaped thin-walled parts of various sizes, reducing processing costs and improving production efficiency.

[0030] Furthermore, anti-slip texture 13 is provided on the outer side of the rotating seat 6; this structure can prevent the user from slipping when rotating the rotating seat 6.

[0031] Furthermore, a positioning pin 14 with matching positioning hole 5 is provided on the rear end surface of the frame 9.

[0032] Furthermore, the rack 11 is provided with an arc-shaped positioning plate 15; this structure can fit the rounded edge of the disc-shaped thin-walled part.

[0033] The working principle of this utility model is as follows: When using this device, first connect the air pump and rotary cylinder to the fixture body through pipes. Then, install the shaft end of the fixture body on the machine tool. Subsequently, place the disc-shaped thin-walled part on the stage 7 (with the workpiece facing down). Then, rotate the rotating seat 6, and drive the small gear 10 through the large gear 8 on the stage 7 to drive the rack 11 to slide towards the axis of the frame 9. This causes the rack 11 to push the disc-shaped thin-walled part towards the center of the stage 7 and align the center of the part with the axis of the frame 9. Then, connect the iris positioning structure to the suction cup 3. Finally, control the air pump to suck up the disc-shaped thin-walled part, thereby achieving the purpose of aligning the center of the part with the axis of the fixture shaft 1. This structure can be adapted to disc-shaped thin-walled parts of various sizes, reducing processing costs and improving production efficiency.
