A motor is mounted on one side of the mounting seat. The output end of the motor is fixedly connected to a coaxially arranged double-ended screw via a coupling. The double-ended screw is rotatably mounted inside the base. A driving bevel gear is fixedly sleeved on the outer circumference of the double-ended screw. Through the arrangement of the double-ended screw and driven screw, when the motor starts, it drives the double-ended screw to rotate, thereby moving two clamping plates towards the center. Simultaneously, the driving bevel gear rotates, driving the two driven bevel gears to rotate, causing the driven screw to rotate, and the other two clamping plates to move towards the center, achieving a four-sided clamping effect for the injection molded part and improving stability.

[0004] In the aforementioned prior art, by controlling the rotation of the double-headed screw, the surrounding clamps can be driven to clamp the electric vehicle injection molded parts. However, the position of the clamps cannot be adjusted individually, and the distance between the surrounding clamps is the same. When clamping long strip injection molded parts, some clamps may not be able to contact the workpiece, affecting the stability of clamping the injection molded parts. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a grinding device for injection molded parts of electric vehicles, thereby solving the problem mentioned in the background art that the clamping plates of the aforementioned grinding device for injection molded parts of electric vehicles cannot be individually adjusted in position, and the distance between the clamping plates on all four sides is the same, which may lead to some clamping plates failing to contact the workpiece when clamping long strip injection molded parts.

[0019] 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.

[0020] Example 1: like Figures 1 to 6 As shown, this utility model provides a grinding device for injection molded parts of electric vehicles, including: a grinding machine 1, and a support base 2 and a support structure arranged on the support base 2 for supporting and fixing the injection molded parts of electric vehicles.

[0021] The support structure includes an L-shaped bracket 201 arranged on the support base 2, an elastic rope 202 arranged on the L-shaped bracket 201 and the grinding machine 1, and a positioning component arranged on the support base 2 for positioning the electric vehicle injection molded parts. The operator can hold the grinding machine 1 to grind the electric vehicle injection molded parts. During the movement of the grinding machine 1, the elastic rope 202 will be stretched and adjusted.

[0022] The positioning components are arranged in multiple sets. Each set of positioning components includes a threaded rod 203 rotatably mounted inside the support base 2, a bevel gear 204 arranged at one end of the threaded rod 203, a bevel gear 205 rotatably mounted inside the support base 2 and meshing with the bevel gear 204, a slide block 206 slidably mounted inside the support base 2, a positioning clamping plate 207 arranged above the slide block 206, a rubber pad arranged on one side of the positioning clamping plate 207, and a threaded seat 208 slidably mounted on the inner wall of the positioning clamping plate 207. The threaded seat 208 and the threaded rod 203 are threaded together. A knob 209 is located at one end of the threaded rod 203. Rotating the knob 209 can drive the corresponding threaded rod 203 to rotate. When the threaded rod 203 rotates, it can drive the threaded seat 208, the fixing screw 3, the positioning clamp 207 and the slide 206 to move, so that the positioning clamp 207 can move closer to the electric vehicle injection molded part. The threaded rod 203 can also drive the corresponding bevel gear 1 204 to rotate. Through the meshing of bevel gear 205 with the other bevel gears 1 204, it is possible to control the surrounding positioning clamps 207 to move closer to the electric vehicle injection molded part at the same time to achieve the clamping and positioning effect.

[0023] Specifically, the positioning assembly also includes a slide bar 210 arranged on one side of the slide block 206, a slide groove 211 formed on the inner wall of the support base 2, the slide bar 210 being slidably installed in the slide groove 211, and two telescopic tubes 212 respectively installed on both sides of the positioning clamp 207 and the slide block 206. One end of the two telescopic tubes 212 is respectively installed on the inner walls of both sides of the support base 2, and the threaded rod 203 is located inside the two telescopic tubes 212. The slide block 206 can drive the slide bar 210 to slide in the slide groove 211. Through the setting of the slide bar 210 and the slide groove 211, the horizontal movement of the slide block 206 and the positioning clamp 207 can be restricted. During the movement of the slide block 206 and the positioning clamp 207, the telescopic tubes 212 on both sides will be driven to extend and retract to adapt. Through the setting of the telescopic tubes 212, the threaded rod 203 can be wrapped to prevent impurities from adhering to the threaded rod 203.

[0024] Example 2: Based on Example 1, an adjustment structure is arranged on the support structure to facilitate the adjustment of the position of the support structure.

[0025] The adjustment structure includes a fixed screw 3 arranged above the threaded seat 208 and slidably installed inside the positioning clamp 207, and a threaded ring 301 threadedly sleeved on the fixed screw 3. The threaded ring 301 is rotatably installed on the positioning clamp 207. Rotating the threaded ring 301 can drive the fixed screw 3 to move up and down through the threaded engagement with the fixed screw 3, so that the fixed screw 3 can drive the threaded seat 208 to rise, so that the threaded seat 208 disengages from the threaded engagement with the threaded rod 203. At this time, the corresponding positioning clamp 207 can be pushed independently to adjust its position.

[0026] The adjustment structure also includes a limiting ring 302 arranged on the positioning clamp 207. The limiting ring 302 is rotatably installed inside the threaded ring 301. Rotating the threaded ring 301 allows it to rotate on the limiting ring 302. The setting of the limiting ring 302 can limit the position of the threaded ring 301 when it rotates, and prevent it from deviating.

[0027] Example 3: Based on Example 2, in order to limit and reinforce the adjustment structure and prevent it from loosening, a limiting structure is arranged on the adjustment structure.

[0028] The limiting structure includes a toothed ring 4 fixedly sleeved on the threaded ring 301, a fixing plate 401 arranged on the positioning clamp 207, a spring 402 arranged on one side of the fixing plate 401, and a toothed plate 403 arranged at one end of the spring 402 and meshing with the toothed ring 4. Under the elastic force of the spring 402, the toothed plate 403 can be pushed to keep the toothed ring 4 in a meshing state, preventing the threaded ring 301 from rotating and loosening. When the toothed plate 403 disengages from the toothed ring 4, it can release the restriction on the threaded ring 301.

[0029] The limiting structure also includes a guide rod 404 arranged at one end of the toothed plate 403. The fixed plate 401 and the spring 402 are both slidably sleeved on the guide rod 404. By pulling the guide rod 404, the toothed plate 403 can be moved. The guide rod 404 can restrict the toothed plate 403 from moving in the horizontal direction and prevent the spring 402 from bending.

[0030] Working principle: The electric vehicle injection molded part is placed between the four positioning clamps 207 on the support base 2. Rotating the knob 209 can drive the corresponding threaded rod 203 to rotate. When the threaded rod 203 rotates, it can move through the threaded engagement with the threaded seat 208, causing the threaded seat 208 to move through the fixing screw 3, thereby moving the positioning clamp 207 and the slide 206. This allows the positioning clamp 207 to move closer to the electric vehicle injection molded part, and the threaded rod 203 can drive the corresponding bevel gear 1 204 to rotate, which in turn drives the bevel gear 205 to rotate. The meshing of bevel gear 205 with the other bevel gears 204 allows bevel gear 205 to drive the surrounding bevel gears 204 and threaded rod 203 to rotate simultaneously. This controls the surrounding positioning clamps 207 to move closer to the electric vehicle injection molded part to achieve the clamping and positioning effect. A rubber pad can be placed on the side of the positioning clamp 207 that is close to the injection molding machine to avoid damage to the injection molded part. At this time, the operator can hold the grinder 1 to grind the electric vehicle injection molded part. During the movement of the grinder 1, the elastic rope 202 will stretch and adapt.

[0031] Pulling the guide rod 404 moves the toothed plate 403, compressing the spring 402 and disengaging it from the toothed ring 4. This releases the restriction on the threaded ring 301. Rotating the threaded ring 301 causes it to rotate on the limit ring 302. The rotating threaded ring 301, through its threaded engagement with the fixed screw 3, moves up and down within the positioning clamp 207, causing the fixed screw 3 to lift the threaded seat 208, disengaging it from the threaded engagement with the threaded rod 203. At this point, the corresponding positioning clamp 207 can be pushed independently, driving the corresponding fixed screw 3 and threaded seat 208 to move. 8. Move the slide block 206. After adjustment, rotate the threaded ring 301 in the opposite direction to reset the fixing screw 3 and the threaded seat 208, so that the threaded seat 208 re-engages with the threaded rod 203. Then, release the guide rod 404. At this time, the spring 402 will push the toothed plate 403 to re-engage with the toothed ring 4, preventing the threaded ring 301 from rotating and loosening. This completes the re-fixing of the position of the positioning clamp 207, thereby achieving the effect of adjusting the position of the single-sided positioning clamp 207 to match the size of the electric vehicle injection molded part. At this time, rotating the knob 209 can still control the positioning clamps 207 around to move closer to or further away from the injection molded part for clamping and positioning.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
