The gear selection control block needs to be processed with a gear selection corrugated groove on the arc-shaped gear selection protrusion. In the prior art, the parts are processed by clamping both ends of the main body. Since the parts do not restrict all degrees of freedom, the position of the parts is easily offset during processing, affecting the processing accuracy of the parts. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the prior art that the parts processing tooling does not restrict all the degrees of freedom of the parts, the parts position is easily offset during processing, and the parts processing accuracy is affected, the present invention provides a gear selection control block processing tooling.

[0004] The technical solution to be adopted by the present invention to solve its technical problems is: a kind of gear selection control block processing tool, the gear selection control block includes a main body, the main body is provided with a center hole along the axial direction, the outer peripheral wall of the main body is provided with a gear selection protrusion, the gear selection protrusion is provided with a protrusion on one side along the circumference of the main body, and a U-shaped positioning block is provided on the other side, the tool includes a bracket, the bracket is provided with a plurality of groups of clamping components for clamping the gear selection control block, the clamping component includes a limit block, a cushion block and a fixed block, one side of the limit block is provided with a central axis, the gear selection control block is sleeved on the central axis through the center hole, the gear selection protrusion faces the side of the machining tool, the cushion block is cushioned under the cushion block or the U-shaped positioning block, a limit portion for preventing the gear selection control block from moving back and forth along the axis of the central axis is provided on the side of the cushion block away from the limit block, the fixed block is provided on the side of the main body away from the limit block, a driving device for driving the fixed block to approach or move away from the main body is provided on the fixed block, and a fixing device for preventing the gear selection control block from rotating along the central axis is also provided on the gear selection control block.

[0005] The gear selection control block needs to be machined with a gear selection corrugated groove on the gear selection protrusion. During machining, the gear selection control block is sleeved on the center axis through the center hole, and the gear selection protrusion faces the side of the machining tool. In order to prevent the staff from loading the material into place when loading the gear selection control block, resulting in part processing errors or mechanical impact, a limit part is provided on the cushion block, and the limit part is used to cooperate with the end of the protrusion or the U-shaped positioning block. The gear selection control block is arranged between the limit block and the limit part to ensure that the material is loaded into place; when loading or unloading the gear selection control block, the gear selection control block needs to be rotated along the center axis by a certain angle to avoid the limit part, so as to facilitate loading and unloading; after the gear selection control block is loaded into place, its position needs to be fixed. On the one hand, it needs to be prevented from rotating along the center axis, and on the other hand, it needs to be prevented from moving along the axis of the center axis (because there will still be some gap between the gear selection control block and the limit part, and it is impossible to be completely stuck). The fixed block cooperates with the limit block to clamp the gear selection control block between the fixed block and the limit block to prevent it from moving along the axis of the central axis; the fixing device cooperates with the cushion block to prevent the gear selection control block from rotating along the central axis.

[0006] Furthermore, in order to prevent the gear selection control block from rotating along the central axis when processing the gear selection waveform groove, the pad is arranged below the U-shaped positioning block, and the fixing device includes a cylinder arranged below the protrusion, and the output end of the cylinder is close to or away from the protrusion. The central axis is the rotation center, and the output end of the cylinder pushes the protrusion. When the U-shaped positioning block abuts against the pad, the gear selection control block no longer rotates along the central axis.

[0007] Furthermore, the driving device comprises a rotary and telescopic hydraulic cylinder, and the fixed block is connected to the output end of the rotary and telescopic hydraulic cylinder.

[0008] When the gear selection control block is loading, the output end of the rotary telescopic hydraulic cylinder is rotated by a certain angle to move the fixed block away from the loading position; after the gear selection control block is loaded onto the center axis, the output end of the rotary telescopic hydraulic cylinder is reversed to move the fixed block to the side of the gear selection control block away from the limit block, and then the output end of the rotary telescopic hydraulic cylinder is contracted to clamp the gear selection control block between the limit block and the fixed block to prevent the gear selection control block from moving along the axis of the center axis during processing.

[0009] Furthermore, a circle of avoidance grooves matching the end of the main body is provided on one side of the fixed block close to the gear selection control block. When the gear selection control block is processed in the previous process, a circle of burrs is formed on the end of the main body. In order to prevent the burrs from affecting the fixing of the position of the gear selection control block, the avoidance grooves are provided to avoid the burr positions.

[0010] Furthermore, the boss is provided with a pin hole connected to the center hole, the bottom wall of the U-shaped positioning block is provided with a threaded hole connected to the center hole, the pin hole and the threaded hole are coaxially arranged, and the center axis is provided with an avoidance hole for facilitating the processing of the pin hole and the threaded hole.

[0011] After the gear selection corrugated groove on the gear selection control block is processed, the bottom hole and the pin hole of the threaded hole are processed and clamped at one time to reduce processing errors. An avoidance hole is set on the center axis to facilitate the processing of the bottom hole and the pin hole of the threaded hole at one time to ensure that the two holes are set coaxially.

[0012] Furthermore, both ends of the bracket are provided with a multi-claw chuck for driving the bracket to rotate. After the gear selection wave groove is processed, the multi-claw chuck drives the bracket to rotate, thereby driving the gear selection control block to be processed on the bracket to rotate, so as to facilitate the tool to process the bottom hole and pin hole of the threaded hole on the gear selection control block.

[0013] Furthermore, in order to ensure that the position angle of the avoidance hole on the central axis corresponds to the position angle of the boss and the U-shaped positioning block, the central axis is fixedly connected to the limiting block via a pin.

[0014] The beneficial effects of the present invention are as follows: a gear selection control block processing tooling provided by the present invention adopts a fixed block and a limit block to limit the movement of the gear selection control block along the axis of the central axis, and adopts a cylinder and a cushion block to limit the rotation of the gear selection control block along the central axis, thereby processing a gear selection corrugated groove on the gear selection protrusion, with fast clamping speed and high processing accuracy, which greatly improves production efficiency and product quality.

The gear protrusion 103 faces the side of the processing tool, and the cushion block 4 is arranged under the U-shaped positioning block 105. The side of the cushion block 4 away from the limit block 3 is provided with a limit portion 401 for preventing the gear selection control block 1 from moving back and forth along the axis of the central axis 6. The side of the main body 101 away from the limit block 3 is provided with the fixed block 5. The fixed block 5 is provided with a rotating telescopic hydraulic cylinder 8 for driving the fixed block 5 to move closer to or away from the main body 101. The output end of the rotating telescopic hydraulic cylinder 8 is connected to the fixed block 5. The gear selection control block 1 is also provided with a cylinder 7 for preventing the gear selection control block 1 from rotating along the central axis 6. When the output end of the cylinder 7 is extended, it presses against the lower side of the boss to prevent the gear selection control block 1 from rotating along the central axis 6.

[0026] like Figure 7 As shown, a circle of avoidance groove 501 matching with the end of the main body 101 is provided on one side of the fixing block 5 close to the gear selection control block 1 .

[0027] Both ends of the bracket 2 are provided with a multi-jaw chuck 9 for driving the bracket 2 to rotate in an angle.

[0028] Working process:

[0029] When loading, the output end of the rotating telescopic hydraulic cylinder 8 controls the fixed block 5 to avoid the loading position of the gear selection control block 1, and the center hole 102 corresponds to the position of the center axis 6. In order to ensure normal loading, Figure 3 As shown, the height h of the limit portion 401 of the cushion block 4 is not greater than the distance H between the lower edge of the protrusion 104 and the output end of the cylinder 7, so that the gear selection control block 1 can be rotated a certain angle along the central axis 6 to avoid the limit portion 401 of the cushion block 4 when loading. After crossing the limit portion 401, the output end of the cylinder 7 extends out to lift the boss, the gear selection control block 1 rotates along the central axis 6, the lower edge of the U-shaped positioning block 105 is in contact with the cushion block 4, and the gear selection control block 1 is arranged between the limit block 3 and the limit portion 401.

[0030] Then the output end of the rotating telescopic hydraulic cylinder 8 drives the fixed block 5 to rotate, so that the position of the fixed block 5 corresponds to the position of the main body 101 of the gear selection control block 1, and then the output end of the rotating telescopic hydraulic cylinder 8 contracts, approaches and clamps the gear selection control block 1, and then starts to process the gear selection corrugated groove on the gear selection protrusion 103.

[0031] After the gear selection corrugated groove is processed, the multi-jaw chuck 9 drives the bracket 2 to rotate a certain angle, and the processing tool is replaced to process the pin hole 106 and the threaded hole 107 corresponding to the axis position of the avoidance hole 601 on the central shaft 6.
