Description

Technical Field

[0001] This utility model relates to a support fixture, specifically a high-precision washer processing support fixture, belonging to the field of washer processing technology. Background Technology

[0002] During the grinding of high-precision washers, the washers are prone to deformation due to their thinness, poor rigidity, and difficulty in heat dissipation. Using fixtures can effectively fix the washers, preventing them from moving or deforming during grinding, thereby ensuring machining accuracy and product quality.

[0003] However, when the clamping force of the fixture is insufficient or the fit between the fixture and the gasket is not tight, the gasket may shift during the grinding process, resulting in uneven grinding of the gasket tip and uneven or rough surfaces on the gasket, thus affecting its sealing performance and service life. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision washer processing support fixture to solve the above problems. The pressure block drives the slider and the locking block to slide into the slide plate. The compression of the telescopic spring causes the locking block to separate from the base, thereby adjusting the position of the slide plate in the limiting groove, so that it drives the abutment block to limit the side wall of the washer and prevent the washer from shifting during the grinding process.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a high-precision washer processing support fixture includes a base, two abutment mechanisms are slidably installed inside the base, and a plurality of limiting grooves and locking grooves are provided in a ring shape inside the base. A clamping mechanism is slidably installed in the limiting groove, and the clamping mechanism includes a sliding plate and a stop block. The sliding plate is slidably installed in the limiting groove, and the top of the sliding plate is fixedly connected to the stop block. A washer is engaged between the stop block and the abutment mechanism. A sliding groove is provided inside the sliding plate, and two sliders are slidably installed in the sliding groove. A pressure block and a locking block are fixedly connected to the sliders. A telescopic spring is fixedly installed between the two locking blocks, and the locking blocks are engaged with the inner wall of the base.

[0006] Preferably, the portion of the base near the slot is serrated, and the end of the card block that engages with the base is also serrated.

[0007] Preferably, the slide plate is slidably connected to the base, and the end of the slide plate facing away from the abutment block is arranged with an arc surface structure.

[0008] Preferably, the pressure block is located at the top of the slide plate, and the pressure block is slidably connected to the slide plate.

[0009] Preferably, the two telescopic springs are symmetrically arranged about the slider, and the slider and the slide plate are slidably connected.

[0010] Preferably, the abutment mechanism includes a rotating rod and a sliding rod. The rotating rod is rotatably connected to the base, the sliding rod is threadedly connected to the rotating rod, and a stop plate is fixedly connected to the sliding rod. A gasket is adhered to the stop plate.

[0011] Preferably, the slide rod is slidably connected to the base, and the gasket is in contact with the inner wall of the base.

[0012] Preferably, the washer is located at the top of the base, and the washer is located in the middle of the gasket and the abutment.

[0013] Preferably, the part of the abutment that contacts the washer has an arc-shaped structure, and the abutment plate and the washer also have an arc-shaped structure.

[0014] Preferably, the abutment blocks are slidably connected to the base, and a plurality of the abutment blocks are arranged in a ring at equal intervals.

[0015] The beneficial effects of this utility model are as follows: The washer is placed on the top of the base, and the washer is initially limited by the abutment mechanism. Then, the pressure block set on the top of the slide plate is pinched by hand. The pressure block is fixedly connected to the slider. When the two pressure blocks slide towards each other, the slider can drive the locking block fixed to it to slide. When the end of the locking block that is engaged with the inner wall of the base slides into the inside of the slide plate, the locking block can squeeze the telescopic spring. When the telescopic spring is in a compressed state, the locking block can be separated from the base. At this time, moving the slide plate can cause the abutment block fixed at the top to move. When the abutment block moves to the state of abutting the washer, several abutment blocks can limit the outer wall of the washer, thereby preventing the washer from shifting during the grinding process.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 As shown, a high-precision washer processing support fixture includes a base 1. Two abutment mechanisms 3 are slidably installed inside the base 1. The base 1 has a plurality of limiting grooves 5 and locking grooves 6 arranged in a ring shape. A clamping mechanism 4 is slidably installed in the limiting grooves 5. The clamping mechanism 4 includes a sliding plate 401 and a stop block 403. The sliding plate 401 is slidably installed in the limiting grooves 5. The top of the sliding plate 401 is fixedly connected to the stop block 403. A washer 2 is engaged between the stop block 403 and the abutment mechanism 3. The sliding plate 401 has a sliding groove 405. Two sliders 404 are slidably installed in the sliding groove 405. A pressure block 402 and a locking block 406 are fixedly connected to the sliders 404. A telescopic spring 407 is fixedly installed between the two locking blocks 406, and the locking blocks 406 are engaged with the inner wall of the base 1.

[0025] As a technical optimization of this utility model, the part of the base 1 near the slot 6 is provided with a sawtooth structure, and the end of the card block 406 that engages with the base 1 is also provided with a sawtooth structure. When the card block 406 engages with the inner wall of the base 1, the positions of the slide plate 401 and the abutment block 403 can be fixed.

[0026] As a technical optimization of this utility model, the slide plate 401 is slidably connected to the base 1, and the end of the slide plate 401 away from the abutment block 403 is set with an arc surface structure. When the slide plate 401 moves in the limiting groove 5, the abutment block 403 can be moved along with it.

[0027] As a technical optimization of this utility model, the pressure block 402 is located at the top of the slide plate 401, and the pressure block 402 is slidably connected to the slide plate 401. The pressure block 402 drives the slider 404 to move in the slide groove 405, so that the locking block 406 can slide into the interior of the slide plate 401.

[0028] As a technical optimization of this utility model, the two telescopic springs 407 are symmetrically arranged about the slider 404, and the slider 404 is slidably connected to the slide plate 401. The slider 404 drives the locking block 406 to move, so that the two locking blocks 406 can squeeze the telescopic springs 407.

[0029] As a technical optimization of this utility model, the abutment mechanism 3 includes a rotating rod 301 and a sliding rod 302. The rotating rod 301 is rotatably connected to the base 1, and the sliding rod 302 is threadedly connected to the rotating rod 301. A stop plate 303 is fixedly connected to the sliding rod 302, and a gasket 304 is adhered to the stop plate 303. Rotating the rotating rod 301 can drive the sliding rod 302 to move within the base 1.

[0030] As a technical optimization of this utility model, the slide rod 302 is slidably connected to the base 1, the gasket 304 is in contact with the inner wall of the base 1, and the slide rod 302 slides inside the base 1, which can be limited according to the inner diameter of the washer 2.

[0031] As a technical optimization of this utility model, the washer 2 is located at the top of the base 1, and the washer 2 is located in the middle of the pad 304 and the abutment 403. When the two abutments 303 slide towards the washer 2, they can abut against the washer 2.

[0032] As a technical optimization of this utility model, the part of the abutment 403 that contacts the washer 2 is set with an arc surface structure, and the abutment plate 303 and the gasket 304 are also set with an arc surface structure. The setting of the gasket 304 makes it easier to increase the friction between the abutment plate 303 and the washer 2.

[0033] As a technical optimization of this utility model, the abutment 403 is slidably connected to the base 1, and several abutment blocks 403 are arranged in a ring at equal intervals. After the abutment block 403 abuts against the side wall of the washer 2, it can limit the washer 2.

[0034] In use, the operator first places the washer 2 on the top of the base 1, and then uses a tool to rotate the rotating rod 301. The end of the rotating rod 301 has a through hole with a regular hexagonal structure. When the rotating rod 301 is rotated, it can rotate inside the base 1. A sliding rod 302 is threaded onto the rotating rod 301. Because the sliding rod 302 is limited by the base 1, when the rotating rod 301 rotates, the sliding rod 302 can only slide within the base 1. A stop plate 303 is fixed to the top of the sliding rod 302. When the washer 304 adhered to the stop plate 303 contacts the inner wall of the washer 2, the two stop plates 303 can initially limit the washer 2. Next, the operator pinches the pressure block 40 on the top of the sliding plate 401. 2. The pressure block 402 and the slider 404 are fixedly connected. When the two pressure blocks 402 slide towards each other, the slider 404 can drive the locking block 406 fixed to it to slide. When the end of the locking block 406 that is engaged with the inner wall of the base 1 slides into the slide plate 401, the locking block 406 can squeeze the telescopic spring 407. When the telescopic spring 407 is in a compressed state, the locking block 406 can be separated from the base 1. At this time, moving the slide plate 401 can cause the top fixed abutment block 403 to move. When the abutment block 403 moves to a state of contact with the washer 2, several abutment blocks 403 can limit the outer wall of the washer 2, thereby preventing the washer 2 from shifting during the grinding process.
