An auxiliary gripper for slotting pins

Abstract

This utility model relates to the field of pin slotting technology and discloses an auxiliary gripper for pin slotting, including a mounting plate with four sliding grooves. This auxiliary gripper for pin slotting works by turning on an air pump, which generates airflow that is directed into an air supply pipe. Once the airflow reaches the pipe, it exits through air outlets at the four ends. Because the pipe is cross-shaped, the gas exits through these outlets, ultimately blowing the gas onto the bidirectional threaded rod. This effectively prevents debris from entering the bidirectional threaded rod during pin slotting, thus preventing the sliding block from sliding normally within the groove. It also prevents errors in the distance the bidirectional threaded rod moves due to debris during rotation, which could affect the gripper's holding of the pin. Therefore, this significantly improves the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of pin grooving technology, specifically to an auxiliary gripper for pin grooving. Background Technology

[0002] A pin is a mechanical component used to connect and fix parts. It generally consists of a cylindrical part and heads at both ends. Grooving is a processing technique that cuts a groove of a certain depth and width in the center of the pin so that the parts can better fit with the pin and improve the stability of the connection.

[0003] Traditional pin-shaft slotting auxiliary grippers typically use a threaded rod to drive the gripper to move within the groove. However, the gripper generates debris during slotting. If this debris falls into the groove or into the threaded rod, it may affect the threaded rod's ability to drive the gripper. Therefore, traditional gripper structures are generally less practical. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary gripper for pin slotting, which solves the problem mentioned in the background art that traditional auxiliary grippers for pin slotting generally move the gripper within the groove by driving it through a threaded rod. However, some debris is generated during the slotting process. If this debris falls into the groove or the threaded rod, it may affect the threaded rod's ability to move the gripper. Therefore, this leads to the problem that the traditional gripper structure has poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary gripper for slotting pins, comprising a mounting plate, wherein four sliding grooves are formed on the mounting plate, the four sliding grooves being arranged in a rectangular array on the mounting plate, a drive motor is fixedly mounted on both end faces of the mounting plate, and a bidirectional threaded rod is fixedly mounted on the output end of each drive motor, the bidirectional threaded rod extending into the sliding grooves formed on the mounting plate, an air pump is fixedly mounted on the outer end surface of the mounting plate, an air supply pipe is provided in the sliding groove, the air supply pipe is cross-shaped, the air supply pipe extends into the four sliding grooves in the mounting plate, the air supply pipe is connected to the air pump, and a plurality of air outlet holes arranged in a linear array are formed on the outer surface of the air supply pipe.

[0006] By adopting the above technical solution, the air pump is turned on to generate air force and deliver it into the air supply pipe. After the air force is delivered into the air supply pipe, it will be discharged from the air outlets opened on the air supply pipe. Since the air supply pipe is cross-shaped, the air will be discharged from the air outlets at all four ends of the air supply pipe, and finally the air is blown onto the double-sided threaded rod. This can effectively prevent debris from entering the double-sided threaded rod when the pin is slotted, thus preventing the sliding block from sliding normally in the groove. This also effectively prevents the double-sided threaded rod from moving the sliding block by the distance due to debris during rotation, which would affect the gripper's clamping of the pin. Therefore, this greatly improves the practicality of the device.

[0007] Preferably, each of the four grooves on the mounting plate is provided with a sliding block, and each sliding block has two through holes. An air supply pipe passes through the through holes in the sliding block, and a bidirectional threaded rod passes through the through holes in the sliding block in a spiral manner.

[0008] Using the above technical solution, the sliding block in the groove facilitates the movement of the gripper to clamp the pin. The gas supply pipe passing through the through hole prevents the gas supply pipe from affecting the sliding block's movement. The double-threaded rod installed in the through hole can effectively drive the sliding block to move.

[0009] Preferably, the top of the sliding block has a mounting groove, a mounting block is engaged in the mounting groove, a clamp is fixedly mounted on the front surface of the mounting block, and threaded holes are opened on both the top of the sliding block and the mounting block. A positioning bolt is inserted into the threaded hole and passes through the top of the sliding block and the mounting block.

[0010] Using the above technical solution, by removing the positioning bolt from the threaded hole, the restriction of the mounting block is removed. Then, the operator moves the mounting block outward, causing it to move out of the mounting groove. The operator then aligns the mounting block on the appropriate type of gripper with the mounting groove and inserts it into the mounting groove, thus mounting the gripper onto the sliding block. Finally, the operator installs the positioning bolt into the positioning hole, firmly fixing the mounting block into the mounting groove. Therefore, this makes it easier for the operator to replace the gripper.

[0011] Preferably, the mounting groove is T-shaped, the mounting block that engages within the mounting groove is also T-shaped, and the mounting groove and the mounting block are of equal size.

[0012] By adopting the above technical solution, since both the mounting groove and the mounting block are T-shaped and the same size, the mounting block can be stably installed into the mounting groove.

[0013] Preferably, the bidirectional threaded rods at both ends of the chute are located directly above the air outlet on the gas pipe, and the bidirectional threaded rods on both sides of the chute are located directly below the air outlet at the bottom of the gas pipe.

[0014] By adopting the above technical solution, the air supply pipe is cross-shaped, so the gas will be discharged from the air outlets at the four ends of the air supply pipe, and finally the gas will be blown onto the double-sided threaded rod. This can effectively prevent debris from entering the double-sided threaded rod when the pin is slotted, thus preventing it from affecting the normal sliding of the sliding block in the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The auxiliary gripper for slotting the pin utilizes an air pump to generate airflow into the air supply pipe. Once the airflow reaches the pipe, it exits through the air outlets. Because the pipe is cross-shaped, the air is also discharged from the outlets at all four ends, ultimately blowing onto the double-threaded rod. This effectively prevents debris from entering the double-threaded rod during pin slotting, thus avoiding interference with the sliding block's movement within the groove. It also prevents errors in the distance the double-threaded rod moves due to debris during rotation, which could affect the gripper's hold on the pin. Therefore, this significantly improves the device's practicality.

[0016] 2. The slotted pin uses an auxiliary gripper. By removing the positioning bolt from the threaded hole, the restriction of the mounting block is removed. Then, the worker moves the mounting block outward, allowing it to move out of the mounting slot. The worker then aligns the mounting block of the appropriate type of gripper with the mounting slot and inserts it into the mounting slot, thus mounting the gripper onto the sliding block. Finally, the worker installs the positioning bolt into the positioning hole, firmly fixing the mounting block into the mounting slot. This makes it easier for the worker to replace the gripper.

[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: Referring to Figures 1-4, an auxiliary gripper for slotting pins is described. The mounting plate 1 has four sliding grooves 2 arranged in a rectangular array. Drive motors 3 are fixedly mounted on both ends of the mounting plate 1. Bidirectional threaded rods 4 are fixedly mounted on the output ends of the drive motors 3, extending into the sliding grooves 2 on the mounting plate 1. An air pump 5 is fixedly mounted on the outer surface of the mounting plate 1. Air supply pipes 6, which are cross-shaped, are disposed within the sliding grooves 2 and extend into the mounting plate 1. The air supply pipe 6 and the air pump 5 are connected in the four sliding grooves 2 inside. The outer surface of the air supply pipe 6 has a plurality of air outlet holes 7 arranged in a linear array. Each of the four sliding grooves 2 on the mounting plate 1 is provided with a sliding block 8. The sliding block 8 has two through holes 9. The air supply pipe 6 passes through the through holes 9 in the sliding block 8. The bidirectional threaded rods 4 at the front and rear ends of the sliding groove 2 are located directly above the air outlet holes 7 on the air supply pipe 6. The bidirectional threaded rods 4 at the left and right sides of the sliding groove 2 are located directly below the air outlet holes 7 at the bottom of the air supply pipe 6.

[0021] Working principle: The drive motor 3 drives the bidirectional threaded rod 4 to rotate, which in turn causes the sliding block 8 to move the gripper 12 within the groove 2. The gripper 12 then clamps the pin to be slotted. During slotting, some debris is inevitably generated. The operator can then turn on the air pump 5, which generates airflow that is directed into the air supply pipe 6. Once the airflow reaches the pipe 6, it is discharged through the air outlet 7. The shape of pipe 6 is cross-shaped, so the gas will be discharged from the air outlets 7 at the four ends of the gas supply pipe 6, and finally the gas will be blown onto the double-threaded rod 4. This can better prevent debris from entering the double-threaded rod 4 when the pin is slotted, thus preventing the sliding block 8 from sliding normally in the groove 2. This also better prevents the double-threaded rod 4 from moving the sliding block 8 by the distance due to debris during rotation, which would affect the clamping of the pin by the jaw 12. Therefore, this greatly improves the practicality of the device.

[0022] Example 2: Referring to Figures 1-4, an auxiliary gripper 12 for slotting a pin shaft is described. Each of the four sliding grooves 2 on the mounting plate 1 contains a sliding block 8. Each sliding block 8 has two through holes 9. A bidirectional threaded rod 4 passes through each through hole 9 in a threaded manner. A mounting groove 10 is formed at the top of the sliding block 8, and a mounting block 11 is engaged within the mounting groove 10. A gripper 12 is fixedly mounted on the front surface of the mounting block 11. Threaded holes 13 are formed at the top of both the sliding block 8 and the mounting block 11. A positioning bolt 14 is inserted into the threaded hole 13, passing through both the top of the sliding block 8 and the mounting block 11. The mounting groove 10 is T-shaped, and the mounting block 11 engaged within the mounting groove 10 is also T-shaped. The mounting groove 10 and the mounting block 11 are of equal size.

[0023] Working principle: When the gripper 12 needs to be replaced to clamp different pins, the operator removes the positioning bolt 14 from the threaded hole 13. After the positioning bolt 14 is removed from the threaded hole 13, the restriction of the mounting block 11 is removed. Then, the operator moves the mounting block 11 outward, so that the mounting block 11 moves out of the mounting groove 10. Then, the operator aligns the mounting block 11 on the appropriate model of gripper 12 with the mounting groove 10 and inserts it into the mounting groove 10, so that the gripper 12 is installed on the sliding block 8. Then, the operator installs the positioning bolt 14 into the positioning hole, so that the positioning bolt 14 firmly fixes the mounting block 11 into the mounting groove 10. Therefore, it is easier for the operator to replace the gripper 12. Furthermore, the mounting groove 10 and the mounting block 11 are both T-shaped and the same size, so the mounting block 11 can be stably installed in the mounting groove 10.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
