[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1. The utility model sets a clamping mechanism. First, the output of the servo motor causes the gear to rotate, and the tooth plate moves inward due to the rotation of the gear. With the movement of the tooth plate, the mounting rod drives the first moving block to move inward synchronously. At this time, due to the movement of the first moving block, the L-shaped rod flips, and through the flipping of the L-shaped rod, the four square plates all flip inward, so that the second moving block moves inward at the same speed as the first moving block. With the movement of the second moving block and the first moving block, the connecting rod drives the clamping plate to move inward synchronously and clamps the tire, so that when the shaft head machine processes the shaft parts on the tire surface, the position of the tire will not be offset due to the contact of the processing equipment in the shaft head machine, and the tire will not be separated from the processing range of the processing equipment, thereby affecting the normal processing of the tire, improving the stability of the processing of shaft parts in the tire, and facilitating the use of operators.

[0017] Second, the utility model can play a sliding limit effect on the gear by setting the light rod, effectively avoiding the gear from deflecting when moving, thereby affecting the clamping effect of the tire; by setting the second moving groove, the movement of the second moving block can be limited, avoiding the second moving block from deflecting when moving, thereby affecting the clamping effect of the tire; by setting the first moving groove, the movement of the first moving block can be limited, avoiding the direction of the first moving block changing when moving, thereby causing the tire to be unable to be clamped; by setting the sliding groove, the movement of the square plate can be limited, avoiding the square plate from deflecting when moving The displacement groove can be used to limit the movement of the connecting rod to avoid the change of direction of the connecting rod when it moves, which may cause the tire to be unable to be fastened and fixed during processing. The limit groove can be used to limit the movement of the clamping plate to improve the stability of the clamping plate when it moves, and avoid the displacement of the clamping plate, which may affect the clamping effect of the tire. The anchor bolts can be used to stabilize the equipment as a whole, and avoid accidental external collisions, which may cause the equipment to tip over, thereby affecting the processing of the tire center shaft parts.

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-6 As shown, the embodiment of the utility model provides an automatic positioning clamping device for shaft head machining, comprising a box body 1, a support frame 3 is fixedly installed on the top of the box body 1, a bracket 4 is fixedly installed on the middle end of the top of the support frame 3, and a tire 5 is placed on the top of the bracket 4;

[0031] The bottom of the box body 1 is provided with a clamping mechanism 2, which includes a servo motor 201, which is fixedly mounted at the bottom of the box body 1, and the output end of the servo motor 201 is fixedly connected to a gear 202, and tooth plates 203 are provided on both sides of the inner cavity of the box body 1, and the surfaces of the two tooth plates 203 are meshed with the surfaces of the gear 202, and the tops of the two tooth plates 203 are fixedly mounted with mounting rods 204, and the tops of the two mounting rods 204 are fixedly mounted with first moving blocks 205, and the box body 1 A second moving block 206 is provided on both the front and rear sides of the top, a square plate 207 is provided at the middle end of the top of the box body 1, and L-shaped rods 208 are movably connected on all sides of the top of the square plate 207. The bottoms of the four L-shaped rods 208 are movably connected to the tops of the two first moving blocks 205 and the tops of the two second moving blocks 206. The two first moving blocks 205 are fixedly installed with connecting rods 209 on the outer sides of the two second moving blocks 206, and the inner sides of the four connecting rods 209 are fixedly installed with clamps 210.

[0032] By setting the clamping mechanism 2, firstly, the output of the servo motor 201 causes the gear 202 to rotate, and the tooth plate 203 moves inward due to the rotation of the gear 202. As the tooth plate 203 moves, the mounting rod 204 drives the first moving block 205 to move inward synchronously. At this time, due to the movement of the first moving block 205, the L-shaped rod 208 flips, and through the flipping of the L-shaped rod 208, the four square plates 207 flip inward, so that the second moving block 206 and the first moving block 205 keep the same speed and move inward. As the second moving block 206 and the first moving block 205 move, the connecting rod 209 drives the clamping plate 210 to move inward synchronously and clamp the tire 5, so that when the shaft head machine processes the shaft parts on the surface of the tire 5, the position of the tire 5 will not be offset due to the contact of the processing equipment in the shaft head machine, and the tire 5 will not be separated from the processing range of the processing equipment, thereby affecting the normal processing of the tire 5, thereby improving the stability of the processing of the shaft parts in the tire 5 and facilitating the use of the operator.

[0033] Example 2

[0034] In one embodiment, a polished rod 211 is fixedly installed on both sides of the inner cavity of the box body 1, and the two gears 202 are slidably connected to the surfaces of the two polished rods 211. The left and right sides of the top of the box body 1 are provided with a second moving groove 213, and the two second moving blocks 206 are slidably connected in the inner cavity of the two second moving grooves 213. The front and rear sides of the top of the box body 1 are provided with a first moving groove 212, and the bottoms of the two first moving blocks 205 are slidably connected in the inner cavity of the two first moving grooves 212. The top of the box body 1 is provided with a sliding The bottom of the square plate 207 is movably connected to the inner cavity of the sliding groove 214 through a rotating shaft. Displacement grooves 215 are provided around the top of the support frame 3. Four connecting rods 209 pass through the inner cavities of the four displacement grooves 215 and extend to the top of the support frame 3. Limiting grooves 216 are provided around the top of the box body 1. The outer sides of the bottom of the clamping plate 210 are slidably connected to the inner cavities of the eight limiting grooves 216. L-shaped plates 6 are fixedly installed around the box body 1, and the tops of the four L-shaped plates 6 are threadedly connected with anchor bolts 7.

[0035] By setting the light rod 211, the gear 202 can be limited in sliding, effectively preventing the gear 202 from deviating when moving, thereby affecting the clamping effect on the tire 5. By setting the second moving groove 213, the movement of the second moving block 206 can be limited, preventing the second moving block 206 from deviating when moving, thereby affecting the clamping effect on the tire 5. By setting the first moving groove 212, the movement of the first moving block 205 can be limited, preventing the direction of the first moving block 205 from changing when moving, thereby causing the tire 5 to be unable to be clamped. By setting the sliding groove 214, the movement of the square plate 207 can be limited, preventing the square plate 207 from moving. The displacement groove 215 can be used to limit the movement of the connecting rod 209 to avoid the direction of the connecting rod 209 changing during movement, which may cause the tire 5 to be unable to be fastened and fixed during processing. The limiting groove 216 can be used to limit the movement of the clamping plate 210 to improve the stability of the clamping plate 210 during movement, and avoid the displacement of the clamping plate 210, which may affect the clamping effect of the tire 5. The anchor bolts 7 can be used to stabilize the entire device, and avoid accidental external collisions that may cause the device to tip over, thereby affecting the processing of the axle parts in the tire 5.

[0036] When the utility model is working: first, the tire 5 is placed on the top of the bracket 4, and then the output of the servo motor 201 causes the gear 202 to rotate, and the tooth plate 203 moves inward due to the rotation of the gear 202. As the tooth plate 203 moves, the mounting rod 204 drives the first moving block 205 to move inward synchronously. At this time, due to the movement of the first moving block 205, the L-shaped rod 208 is flipped, and through the flipping of the L-shaped rod 208, the four square plates 207 are flipped inward, so that the second moving block 206 and the first moving block 205 move inward at the same speed. As the second moving block 206 and the first moving block 205 move, the connecting rod 209 drives the clamping plate 210 to move inward synchronously, thereby completing the clamping work of the tire 5.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
