[0046] Embodiment one

[0047] As Figures 1 to 6As shown, this embodiment provides a clutch pin assembly fixture, which can realize the rapid positioning and assembly of small-sized parts such as clutch pins 100. The clutch pin assembly fixture includes a bit assembly and a handle 3. The bit assembly includes a bit 1 and a connector 2. The first end of the bit 1 is recessed with a receiving groove 11 for receiving the clutch pin 100. The groove sidewall of the receiving groove 11 extends radially along the bit 1 and has a through hole 12 that communicates with the receiving groove 11. One end of the connector 2 is used to pass through the through hole 12 and is inserted into the through hole 101 of the clutch pin 100 in the receiving groove 11. The connector 2 is detachably connected to the bit 1. Next, the side wall of the receiving groove 11 is also provided with an opening 13, which communicates with the receiving groove 11. The through hole 12 is arranged opposite to the opening 13. It should be noted that the through hole 12 and the opening 13 can be arranged with the through hole 12 directly opposite the opening 13, or with the through hole 12 obliquely opposite the opening 13. When the connector 2 passes through the through hole 12 and the through hole 101 of the clutch pin 100 and is installed on the bit 1, the opening of the through hole 101 can be partially or completely exposed in the opening 13. The handle 3 is detachably connected to the second end of the bit 1. The handle 3 can drive the bit 1 to rotate, so that the clutch pin 100 can rotate.

[0048] By passing one end of the connector 2 through the through hole 12 and inserting it into the through hole 101 of the clutch pin 100 within the receiving groove 11, torque can be provided to the clutch pin 100, facilitating its rotation. The addition of the handle 3 increases the turning arm, reducing operator effort and preventing deformation and breakage of both the bit 1 and the handle 3. When installing the clutch pin 100 into the housing 200, the receiving groove 11 of the bit 1 is axially inserted into the head of the clutch pin 100. Then, the connector 2 is installed. Rotating the handle 3 drives the bit 1 to rotate, which in turn drives the connector 2 to rotate, thus rotating the clutch pin 100. This installation process is convenient and efficient. By providing an opening 13 on the side wall of the receiving groove 11, and positioning the through hole 12 opposite to the opening 13, the position of the through hole 101 of the clutch pin 100 can be easily observed from the opening 13, thus facilitating the insertion of the connector 2 into the through hole 101 of the clutch pin 100, further improving assembly efficiency. Furthermore, the handle 3 and the bit 1 are detachably connected, facilitating disassembly and assembly, reducing manufacturing difficulty. Damage to some components will not affect the overall use; the handle 3 or bit 1 can be replaced individually after damage, reducing manufacturing costs. Figure 4 As shown, during assembly, the clutch pin 100 is first fixed using the connector 2 and the bit 1, and then the bit 1 is connected to the handle 3. The handle 3 is rotated to install the clutch pin 100 into the corresponding position on the housing 200, and the clutch pin 100 is tightened on the other side using a spring washer and a nut.

[0049] Optionally, the opening 13 is configured as an entrance for the clutch pin 100 to enter the accommodating groove 11 in the radial direction of the head 1. The clutch pin 100 can enter the accommodating groove 11 in the axial direction of the head 1. In this way, the clutch pin 100 can also enter the accommodating groove 11 in the radial direction of the head 1, making the connection between the clutch pin 100 and the head 1 more flexible and convenient.

[0050] Optionally, as shown in Figure 1 the opening 13 extends from the end face of the first end of the head 1 in the axial direction, and the length of the extension is equal to the groove depth of the accommodating groove 11, that is, the opening 13 extends to the groove bottom of the accommodating groove 11, so that the groove bottom surface of the accommodating groove 11 is flush with the bottom surface of the opening 13, facilitating processing. Alternatively, the opening 13 extends from the end face of the first end of the head 1 in the axial direction, and the length of the extension is less than the groove depth of the accommodating groove 11. In this way, it is ensured that the position of the through hole 101 of the clutch pin 100 can be observed at the opening 13, while the accommodating groove 11 can completely surround the end of the clutch pin 100 close to the end of the head 1 in the circumferential direction, avoiding the disengagement of the clutch pin assembly tool from the clutch pin 100 during rotation.

[0051] Further, the groove surface of the accommodating groove 11 is in contact with the outer wall surface of the clutch pin 100, and part or all of the groove side walls of the accommodating groove 11 are in a semi-ring structure. The groove surface of the accommodating groove 11 is in contact with the outer wall surface of the clutch pin 100, which facilitates the rotation of the clutch pin 100, making the through hole 101 of the clutch pin 100 communicate with the opening 13, and also plays a role in positioning the clutch pin 100. When the opening 13 extends from the end face of the first end of the head 1 in the axial direction and the length of the extension is equal to the groove depth of the accommodating groove 11, all the groove side walls of the accommodating groove 11 are in a semi-ring structure. When the opening 13 extends from the end face of the first end of the head 1 in the axial direction and the length of the extension is less than the groove depth of the accommodating groove 11, part of the groove side walls of the accommodating groove 11 are in a semi-ring structure. In this way, it is convenient for the clutch pin 100 to enter the accommodating groove 11 in the radial direction of the head 1, while the structural strength of the head 1 is improved. Part or all of the groove side walls of the accommodating groove 11 are in a semi-ring structure, that is, a ring structure with a central angle of 180 degrees. In other embodiments, part or all of the groove side walls of the accommodating groove 11 can be in a ring structure with a central angle greater than 180 degrees, which can insert the clutch pin 100 into the accommodating groove 11 in the axial direction of the head 1, and also avoid the disengagement of the head 1 and the plug-in part 2 from the clutch pin 100. Of course, part or all of the groove side walls of the accommodating groove 11 can also be in a ring structure with a central angle less than 180 degrees.

[0052] Optionally, in the present embodiment, the groove surface of the accommodating groove 11 is used to contact and magnetically connect with the outer wall surface of the clutch pin 100. In this way, reliable connection between the clutch pin 100 and the accommodating groove 11 can be achieved. Specifically, a magnetic attraction layer made of a magnetic material can be provided on the groove surface of the accommodating groove 11.

[0053] To ensure reliable installation of the plug-in part 2 and the bit 1, the through hole 12 is optionally provided with an internal thread, and the plug-in part 2 is provided with an external thread, and the plug-in part 2 is threadedly connected with the through hole 12.

[0054] Optionally, the handle 3 comprises a handle body 31 and a handle head 32, the handle head 32 is arranged at one end of the handle body 31, and the width of the handle head 32 is greater than the width of the handle body 31. Optionally, the width of the middle part of the handle body 31 is greater than the width of the two end parts, and the handle body 31 is provided with a round chamfer, which can improve the comfort of the user and prevent scratching. Optionally, the accommodating groove 11 of the bit 1 is provided with a round chamfer, and the opening 13 is provided with a guide surface, which can facilitate operation and also avoid scratching and knocking.

[0055] Optionally, the plug-in part 2 is a plug-in rod, the outer diameter of the plug-in rod, the inner diameter of the through hole 12 and the inner diameter of the through hole 101 of the clutch pin 100 are the same, which can ensure that the plug-in rod passes through the through hole 12 and the through hole 101 in sequence to position the clutch pin 100. In addition, after the handle 3 and the bit 1 are installed together, the sum of the length of the handle 3 and the length of the bit 1 in the axial direction of the bit 1 is less than the length of the inner cavity of the box body 200, so that the handle 3 and the bit 1 are located in the inner cavity of the box body 200, and the assembly operation of the clutch pin 100 can be performed in the smaller space of the box body 200, which is simple and convenient to operate.

[0056] The second end of the bit 1 of the embodiment is recessed with a plug-in groove 14, and the groove side wall of the plug-in groove 14 is provided with a limiting groove 1404; the handle 3 is provided with a pressing part 4, and the pressing part 4 and the handle 3 are connected with an elastic part 6, the elastic part 6 is configured to exert an elastic force to place the pressing part 4 outside the handle 3, the side wall of the pressing part 4 is provided with a stepped groove 41, and the stepped groove 41 is provided with a ball 5; specifically, the handle 3 is recessed with a mounting groove 302, one end of the pressing part 4 and the groove wall of the mounting groove 302 are connected with the elastic part 6, and the other end of the pressing part 4 is placed outside the mounting groove 302. One end of the handle 3 is used for being inserted into the plug-in groove 14, and the stepped groove 41 makes the ball 5 partially pass through the handle 3 and abut against the limiting groove 1404, and when the pressing part 4 is pressed, the stepped groove 41 makes the ball 5 separate from the limiting groove 1404. Specifically, one end of the handle 3 is provided with a plug-in block 33, and the plug-in block 33 is inserted into the plug-in groove 14.

[0057] When disassembling, the pressing piece 4 is pressed, the elastic piece 6 is compressed, the ball 5 rolls into the groove with a deeper depth in the stepped groove 41 on the pressing piece 4, and the handle 3 and the head 1 can be separated; when the pressing piece 4 is released, the ball 5 rolls into the groove with a shallower depth in the stepped groove 41 on the pressing piece 4, and abuts against the limiting groove 1404, so that the handle 3 and the head 1 can be installed. In this way, while avoiding the relative rotation between the handle 3 and the head 1 in the radial direction, the handle 3 and the head 1 are conveniently disassembled and assembled. Specifically, the stepped groove 41 includes a first groove body 411 and a second groove body 412 arranged in sequence along the axial direction of the pressing piece 4, the groove depth of the first groove body 411 is smaller than the groove depth of the second groove body 412, when the pressing piece 4 is pressed, the ball 5 rolls into the second groove body 412, and when the pressing piece 4 is released, the ball 5 rolls into the first groove body 411 and abuts against the limiting groove 1404.

[0058] Optionally, the stepped groove 41 is provided with four stepped grooves 41, and the four stepped grooves 41 are arranged at intervals along the circumferential direction of the pressing piece 4. In this way, the installation between the handle 3 and the head 1 is more reliable, and the rotation of the clutch pin 100 is also facilitated.

[0059] Optionally, the slot cavity of the insertion groove 14 is a regular quadrangular prism cavity, and the insertion block 33 is conformal with the slot cavity of the insertion groove 14. In this way, the handle 3 can better drive the head 1 to rotate, and the relative rotation between the handle 3 and the head 1 in the radial direction can be further avoided.

[0060] Embodiment Two

[0061] The embodiment provides a clutch pin assembly tool, which can quickly position and assemble the small-size parts such as the clutch pin 100. The clutch pin assembly tool includes the head assembly and the handle 3. The main difference between the clutch pin assembly tool provided by the embodiment and the clutch pin assembly tool of the first embodiment is that the detachable connection structure of the handle 3 and the head 1 is different. The same structure as the first embodiment is not described herein.

[0062] The second end of the batch head 1 is concavely provided with a plug-in groove 14. One of the handle 3 and the batch head 1 is provided with a guide groove 1401, and the other is provided with a guide piece 301. The guide piece 301 is plugged into the guide groove 1401. When the handle 3 drives the batch head 1 to rotate, the guide piece 301 abuts against the guide groove 1401. In this way, the handle 3 can drive the batch head 1 to rotate, and the relative rotation between the handle 3 and the batch head 1 in the radial direction can be avoided. Specifically, the plug-in groove 14 is located at the central position of the second end of the batch head 1. In addition, the guide groove 1401 can be one or more. When the guide groove 1401 is more than one, the plurality of guide grooves 1401 are circumferentially spaced along the groove side wall of the plug-in groove 14. The plurality of guide pieces 301 are correspondingly arranged with the plurality of guide grooves 1401, so that the installation between the handle 3 and the batch head 1 is more reliable, and the rotation of the clutch pin 100 is also facilitated.

[0063] Optionally, the guide groove 1401 is a strip-shaped groove, and the guide piece 301 is a strip-shaped protrusion. The strip-shaped protrusion is plugged into the strip-shaped groove along the axial direction of the batch head 1, and the strip-shaped protrusion can abut against the strip-shaped groove. When connecting, the strip-shaped protrusion is aligned with the strip-shaped groove, and the handle 3 is inserted into the plug-in groove 14 along the axial direction of the batch head 1. When disassembling, the handle 3 is pulled out. In this way, the structure is simple, and the disassembly is facilitated.

[0064] Further, as shown in Figure 7 , the groove side wall of the plug-in groove 14 is concavely provided with a strip-shaped groove, and the handle 3 is provided with a strip-shaped protrusion. Specifically, one end of the handle 3 is provided with a plug-in block 33, and the plug-in block 33 is provided with a strip-shaped protrusion. In addition, the strip-shaped groove is provided with four. In addition, the strip-shaped protrusion can also be provided on the groove side wall of the plug-in groove 14, and the strip-shaped groove is concavely provided on the handle 3.

[0065] Specifically, the cavity of the plug-in groove 14 is a regular quadrangular prism cavity, and the plug-in block 33 is conformal with the cavity of the plug-in groove 14. In this way, the relative rotation between the handle 3 and the batch head 1 in the radial direction can be further avoided. In addition, in order to ensure the reliability of the connection, the strip-shaped groove and the strip-shaped protrusion are plugged and magnetically connected. For example, magnets are arranged in the strip-shaped groove and the strip-shaped protrusion for adsorption.

[0066] Optionally, as shown in Figures 8 to 11As shown, the slot side wall of the insertion slot 14 is concavely provided with a guide slot 1401, and the handle 3 is provided with a guide piece 301. The guide slot 1401 includes an axial guide slot 1402 extending along the axial direction of the bit 1 and a circumferential guide slot 1403 extending along the circumferential direction of the bit 1. One end of the axial guide slot 1402 penetrates the second end face of the bit 1, and the other end of the axial guide slot 1402 communicates with the circumferential guide slot 1403. The axial guide slot 1402 is used for the axial sliding of the guide piece 301 and sliding to the circumferential guide slot 1403, and the guide piece 301 abuts against the slot wall of the circumferential guide slot 1403. Through the above arrangement, the guide piece 301 can be rotated into the circumferential guide slot 1403, and when the rotating clutch pin 100 is rotated, the accidental falling of the handle 3 from the bit 1 along the axial direction is reduced.

[0067] Optionally, the guide piece 301 axially slidable in the axial guide slot 1402 and abutting against the slot wall of the circumferential guide slot 1403 is an elastic abutting piece, the slot depth of the circumferential guide slot 1403 is greater than the slot depth of the axial guide slot 1402, and the axial guide slot 1402 and the circumferential guide slot 1403 are smoothly connected at the joint. Specifically, the elastic abutting piece is an elastic buckle. When the handle 3 and the bit 1 are installed, the elastic buckle first axially slides along the axial guide slot 1402 and is in a compressed state. When the elastic buckle slides to the circumferential guide slot 1403, the handle 3 is rotated to make the elastic buckle open and abut against the slot bottom of the circumferential guide slot 1403. Continue to rotate the handle 3, and the elastic buckle can abut against one of the opposite two end faces of the circumferential guide slot 1403 along the circumferential direction, thereby limiting the axial position between the handle 3 and the bit 1. When disassembling, the handle 3 is rotated in the opposite direction, the elastic buckle enters the axial guide slot 1402 from the circumferential guide slot 1403, and slides out of the axial guide slot 1402. The elastic buckle is a mature technology in the related field, and this embodiment will not be described again.

[0068] Specifically, the axial guide slot 1402 and the circumferential guide slot 1403 are connected to form an L-shaped structure, and the elastic abutting piece can reliably abut against one of the opposite two end faces of the circumferential guide slot 1403 along the circumferential direction, which is away from the axial guide slot 1402, so that the processing is more convenient. Further, the four L-shaped structures are symmetrically distributed, which is convenient for processing. Alternatively, the axial guide slot 1402 and the circumferential guide slot 1403 are connected to form a T-shaped structure. In this way, when the handle 3 is rotated, the elastic abutting piece can selectively and reliably abut against the opposite two end faces of the circumferential guide slot 1403 along the circumferential direction, thereby achieving bidirectional locking of the handle 3 relative to the bit 1, and further avoiding accidental falling of the handle 3 from the bit 1 along the axial direction. Further, the four T-shaped structures are symmetrically distributed, which is convenient for processing.

[0069] In order to facilitate the rotation of the handle 3 when the handle 3 and the bit 1 are installed, specifically, the slot cavity of the insertion slot 14 is a cylindrical cavity, and the insertion block 33 is shaped with the slot cavity of the insertion slot 14.

[0070] In addition, the elastic abutting piece is in sliding connection with the axial guide groove 1402 and the circumferential guide groove 1403. In this way, the connection reliability can be improved. Alternatively, the sliding surfaces of the elastic abutting piece, the axial guide groove 1402 and the circumferential guide groove 1403 are provided with magnetic attraction layers made of magnetic materials.

[0071] Obviously, the above embodiments of the present application are merely exemplary for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is not necessary and impossible to enumerate all the embodiments.
