[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] like Figures 1 to 5As shown, the wheel anti-tilting inner clamp of this utility model includes a clamp body 1, a mounting assembly 2, a clamping jaw 3, an elastic pad 4, and a pressure plate assembly 5. The clamp body 1 is mounted on the chuck via the mounting assembly 2. The clamping jaw 3 is located on the top of the clamp body 1 for clamping the wheel. The elastic pad 4 is located between the bottom of the clamping jaw 3 and the clamp body 1. The pressure plate assembly 5 is located on one side of the clamping jaw 3 and is slidably connected to the clamp body 1.

[0031] The elastic pad 4 includes a connecting plate 41, a sliding bolt 42, a disc spring 43, and a washer 44. The connecting plate 41 has symmetrical fixed grooves 411 on both sides, and spring grooves 412 are provided on both sides of the connecting plate 41 near the fixed grooves 411. The sliding bolt 42 is slidably disposed in the fixed grooves 411. One end of the disc spring 43 is connected to the spring groove 412, and the washer 44 is disposed at the other end of the disc spring 43.

[0032] The pressure plate assembly 5 includes a sliding block 51, a limiting block 52, and a fixing screw 53. The limiting block 52 is located at the bottom of the sliding block 51, and the sliding block 51 is fixed to the gripper 3 by the fixing screw 53.

[0033] Furthermore, in the anti-tilting inner clamp for wheels of this utility model, a mounting groove 11 is provided on one side of the top of the clamp body 1, an abutment platform 12 is provided at the bottom of the mounting groove 11, the side of the mounting groove 11 is provided with a 65° inclined structure, a 65° limiting slide groove 13 is provided on the side of the clamp body 1 near the mounting groove 11, the limiting slide groove 13 is provided parallel to one side of the mounting groove 11, and a connecting slide groove 14 is provided between the mounting groove 11 and the limiting slide groove 13.

[0034] Furthermore, in the aforementioned anti-tilting inner clamp for wheels, the bottom of the clamp 3 is provided with a connecting groove 31, and the middle of the connecting groove 31 is symmetrically provided with a first threaded hole 32. The depth of the connecting groove 31 is equal to the thickness of the washer 44. The washer 44 abuts against the bottom of the clamp 3. The sliding bolt 42 passes through the fixed slide groove 411 and engages with the first threaded hole 32. The connecting plate 41 abuts against the abutment platform 12. The distance between the connecting plate 41 and the clamp 3 is less than or equal to the height of the disc spring 43. Thus, when the clamp 3 moves downward, the washer 44 is forced to compress the disc spring 43. At the same time, the fixed slide groove 411 slides along the sliding bolt 42. When the clamp 3 is no longer under force, the disc spring 43 rebounds and drives the clamp 3 to reset.

[0035] Furthermore, in the anti-tilting inner clamp for wheels of this utility model, the limiting groove 13 includes a sliding groove 131 and a limiting groove 132. The limiting groove 132 is disposed at the bottom of the sliding groove 131, the sliding block 51 is slidably disposed in the sliding groove 131, and the limiting block 52 is slidably disposed in the limiting groove 132, thereby effectively ensuring that the sliding block 51 slides along the extension direction of the sliding groove 131, while the limiting block 52 limits the sliding block 51 to prevent it from sliding out of the sliding groove 131.

[0036] Furthermore, in the anti-tilting inner clamp for wheels of this utility model, a slide 33 is provided on the back of the gripper 3. The slide 33 is set with a 65° inclined structure. A second threaded hole 34 is provided on the slide 33. The fixing screw 53 passes through the sliding block 51 and the connecting slide groove 14 and engages with the second threaded hole 34. The slide 33 is slidably connected to the side of the mounting groove 11, thereby ensuring that the gripper 3 slides down the slide 33 slightly along the side of the mounting groove 11 under the reaction of the clamping force, thereby offsetting the amount of tilting of the clamp body 1 with the sliding pair of the rack.

[0037] Furthermore, in the anti-tilting inner clamp for wheels of this utility model, the mounting component 2 includes a key bar 21 and T-screws 22. The key bar 21 is fixed to the bottom of the clamp body 1 by bolts, and the bottom of the T-screws 22 are arranged and welded to the key bar 21. The top of the T-screws 22 engages with the chuck's synchronous rack, thereby effectively ensuring that the clamp body 1 and the chuck are installed synchronously.

[0038] Specifically, in use, at least three clamping bodies 1 are first connected to the chuck synchronous rack via the mounting assembly 2 at the bottom. The chuck rack is then adjusted to move the clamping bodies 1 towards the chuck center. When the jaws 3 contact the wheel and continue moving towards the chuck center, the jaws 3, via the fixing screws 53, ensure that the slide 33 remains in contact with the mounting groove 11. Under the reaction force of the clamping force, the jaws 3 slide slightly downwards along the side of the 65° inclined mounting groove 11 on the clamping body 1 via the slide 33. Simultaneously, the jaws 3, via the fixing screws 53, cause the sliding block 51 to slide within the sliding groove 131. The fixing screw 53 slides along the connecting groove 14 to ensure the stability of the gripper 3 when it slides. At the same time, the limiting block 52 slides with the gripper 3 in the limiting groove 132 to ensure the maximum or minimum sliding distance of the gripper 3. At this time, the bottom of the gripper 3 squeezes the disc spring 43 through the shim 44, so that the disc spring 43 is compressed. Meanwhile, the fixing groove 411 slides downward along the sliding bolt 42, thereby offsetting the upward tilt of the clamp body 1 with the rack sliding pair, ensuring that the wheel is always in close contact with the positioning and height support block installed on the chuck. When it is released, the gripper 3 resets under the rebound force of the disc spring 43.

[0039] In summary, compared with the prior art, the anti-tilting inner clamp for wheels of this utility model has the following advantages and beneficial effects:

[0040] The overall structure is simple. The cooperation between the gripper and the pressure plate assembly effectively offsets the upward tilt of the gripper body as it slides along the rack and pinion, ensuring that the wheel is always in close contact with the positioning support block installed on the chuck, thus effectively improving product quality and production efficiency.
