Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical assembly, and in particular relates to a screw-type handle assembly device. Background Art

[0002] Currently, the assembly of the handle itself mainly involves assembling and connecting the grip and the external part, wherein a mounting hole is formed on the grip, and a docking shaft is formed on the external part. The docking shaft then needs to be inserted into the mounting hole to complete the assembly. In general, the docking shaft and the mounting hole are tightly fitted together, so conventional assembly is performed by hammering. This has the following drawbacks:

[0003] 1) Due to different striking forces, the assembly may not be in place or may be over-assembled, which not only fails to meet the required assembly depth, but also increases the deformation or damage rate of the handle or external parts;

[0004] 2) Once the alignment angle changes without being discovered, forcible striking will increase the scrap rate of the handle and external parts, thereby increasing the handle processing cost. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a new screw-type handle assembly device.

[0006] In order to achieve the above purpose, the solution adopted by the utility model is:

[0007] A screw-type handle assembly device assembles a handle and an external component into a handle, an assembly hole is formed on the handle, and a docking axis is formed on the external component. The handle assembly device includes an assembly platform, a handle positioning seat formed on the assembly platform and capable of self-rotation, and an external component positioning seat that can be adjusted up and down on the assembly platform, wherein the handle is mounted on the handle positioning seat with the self-assembly hole facing upward, and the external component positioning seat can set a movement stroke, and the external component is mounted on the external component positioning seat with the self-docking axis facing downward, and the center line of the handle positioning seat's rotation, the center line of the assembly hole, and the center line of the docking axis coincide, and within the movement stroke, the external component and / or the external component positioning seat are pressed down to perform screwing assembly of the docking axis and the assembly hole.

[0008] Preferably, the handle positioning seat includes a rotating base mounted on an assembly platform that rotates around a vertical direction, and an assembly seat formed on the rotating base and capable of matching the handle, wherein the assembly seat is matched and inserted with the lower end of the handle.

[0009] In some embodiments, the lower part of the handle forms an insertion hole, and the assembly seat is provided with an assembly core matched with the insertion hole, wherein the assembly core and the insertion hole are matched by protrusions and grooves to keep synchronous rotation. In this way, the handles can be assembled in the same state, and the control of the insertion depth is facilitated, and the handle can be unloaded after assembly.

[0010] According to one embodiment and preferred aspect of the present application, a wheel disc is arranged coaxially at the bottom of the rotating base, and the handle assembly device further comprises a rotating component for driving the wheel disc to rotate around its own axis. The synchronous rotation of the rotating base is realized by rotating the wheel disc.

[0011] Preferably, the rotating component comprises a power disc, a transmission member for transmission connection between the power disc and the wheel disc, and a motor for driving the power disc to rotate. The conventional transmission member can be a transmission chain or a transmission belt. In this case, the power disc and the wheel disc are both pulleys, and the transmission member is a transmission belt with a rack.

[0012] Alternatively, the wheel disc is a gear disc, and the rotating component comprises a power disc engaged with the gear disc and a motor for driving the power disc to rotate.

[0013] According to one embodiment and preferred aspect of the present application, a bracket extending upward and downward is arranged on one side of the handle positioning seat, and the external component positioning seat can be adjusted upward and downward relative to the bracket. That is, the control of the screwing amount is based on the upward and downward movement of the bracket.

[0014] Preferably, a sliding rail is arranged on the bracket, and the external component positioning seat is arranged on the sliding rail and can slide upward and downward. The movement guide is formed based on the sliding rail, and the stroke control is facilitated.

[0015] In some embodiments, a sliding seat capable of sliding adjustment is arranged on the sliding rail, and a stroke switch capable of contacting the external component positioning seat is arranged on the sliding seat. When the external component positioning seat touches the stroke switch and then descends, the external component is prevented from being screwed in. Based on the position of the stroke switch, the screwing amount required for installation is effectively controlled, and based on the adjustment of the sliding seat, the handle assembly with different screwing amounts is facilitated.

[0016] In addition, a reset spring is arranged between the top of the bracket and the external component positioning seat. When the downward pressure is released, the reset spring drives the external component positioning seat to reset and keep the connecting shaft above the assembly hole. That is, once the assembly is completed, when the manual downward pressure or the downward pressure applied by other mechanisms is unloaded, the external component positioning seat is pulled upward by the reset spring, and the handle is gradually pulled out of the handle positioning seat, thereby assisting the unloading. Therefore, the functions of the reset spring are as follows: 1. assisting the reset of the external component positioning seat; and 2. assisting the unloading of the assembled handle.

[0017] The utility model discloses the following advantages compared with prior art due to the above technical and equipment scheme:

[0018] In the existing handle assembly, all are assembled by knocking, and due to the different knocking force, the assembly may not be in place or be over assembled, which not only cannot meet the need of assembly depth, but also increases the deformation or damage rate of the grip or external part by knocking. Meanwhile, if the alignment angle changes and is not found, forced knocking will increase the scrap rate of the grip and external part, and further increase the handle processing cost and other defects. The structure of the screwing type handle assembly equipment is designed as a whole, and the defects of the prior art are skillfully solved. After using the assembly equipment, firstly, the grip and external part are positioned to the corresponding positioning seat, and the handle positioning seat, the center line of the assembly hole and the center line of the connecting shaft coincide; secondly, the external part positioning seat or the external part is pressed downward, so that the connecting shaft is inserted into the rotating assembly hole to implement screwing; finally, after reaching the movement stroke, the screwing is stopped, and the handle assembly of the required screwing amount can be implemented. Therefore, on the one hand, based on the coincidence of the handle positioning seat, the center line of the assembly hole and the center line of the connecting shaft, the connecting shaft is inserted and assembled, and the assembly angle deviation does not occur, and knocking is not needed. On the other hand, based on the movement of the inserted motion, the screwing amount is controlled, so that the insertion depth uniformity of the handle assembly is maintained, the assembly quality is improved, the assembly efficiency is also increased, and the handle scrap rate is low.

When the handle B is assembled, the docking shaft b20 needs to be inserted into the assembly hole b10 (note that it is not a threaded connection here, but a conventional interference fit assembly).

[0040] As shown in Figures 2 to 5 The handle assembly device of the embodiment includes an assembly platform 1, a handle positioning seat 2 formed on the assembly platform 1 and capable of self-rotation, and an external member positioning seat 3 mounted on the assembly platform 1 in an up-down adjustable manner. The grip b1 is mounted on the handle positioning seat 2 with the assembly hole b10 facing upwards, and the external member positioning seat 3 can set the movement stroke, and the external member b2 is mounted on the external member positioning seat 3 with the docking shaft b20 facing downwards.

[0041] Specifically, the assembly platform 1 includes a platform panel 10 and a frame 11.

[0042] The handle positioning seat 2 comprises a rotating base 20 installed on the platform panel 10 around the vertical direction, and an assembly seat 21 formed on the rotating base 20 and capable of matching the handle, wherein an assembly core 210 is formed on the assembly seat 21, the lower end of the handle b1 is formed with a plug-in hole matched with the assembly core 210, and considering the motion synchronization and the later convenient unloading features after plugging, a matching groove a is formed on the circumference of the assembly core 210, and a convex edge matched with the matching groove is formed on the inner wall of the plug-in hole (not shown in the drawing, but not difficult to think of), that is, the plug-in of the matching groove a and the convex edge is formed.

The rotating member 5 comprises a power disc 50, a transmission member for transmission connection between the power disc 50 and the wheel disc 4, and a motor 51 for driving the power disc 50 to rotate. In this case, the power disc 50 and the wheel disc 4 are both belts, and the transmission member is a transmission belt with a rack. Of course, the wheel disc is a gear disc, the rotating member comprises a power disc engaged with the gear disc, and a motor for driving the power disc to rotate.

[0044] In this case, a bracket 6 extending up and down is arranged on one side of the handle positioning seat 2, and the external member positioning seat 3 can be adjusted up and down on the bracket 6.

Based on the position layout of the stroke switch, the screwing amount required for installation is effectively controlled, and based on the adjustment of the sliding seat, the handle assembly of different screwing amounts can be satisfied.

[0046] Furthermore, a return spring 9 is provided between the top of the bracket 6 and the external component locating seat 3. When downward pressure is released, the return spring 9 resets the external component locating seat 3 and maintains the docking axis b20 directly above the assembly hole b10. In other words, the rotational centerline of the handle locating seat, the centerline of the assembly hole, and the centerline of the docking axis coincide with each other. During the range of motion, the external component and / or the external component locating seat are pressed downward to engage the docking axis and the assembly hole.
