Fig. 1 to 7 are schematic structural views of the assembly mechanism of the present embodiment. The assembling mechanism is used for accurately assembling the two workpieces together, so that the assembled size of the two workpieces can reach the preset size H. For ease of understanding, reference may be made to the following examples: as shown in fig. 3, the first workpiece a is a housing, the second workpiece B is an interface connected with a cable, and the first workpiece a is assembled and sleeved on the outside of the second workpiece B to form a workpiece assembly C for use (i.e., the housing is sleeved on the outside of the interface and the cable to form a complete interface product). The size of the workpiece assembly C formed by assembling the first workpiece A and the second workpiece B can satisfy the following conditions: after assembly, the distance between the two side edges of the first workpiece A and the second workpiece B which are farthest from each other is the preset dimension H. The predetermined dimension H may be set according to the requirements of the workpiece assembly C in use, for example, the predetermined dimension H is 8.00 ± 0.05 mm.

As shown in fig. 1, the assembly mechanism includes a carrier table 1, a driving assembly 2, a first carrier assembly 3, a second carrier assembly 4, a sliding rod 5 and an adjusting knob 6. The bearing surface of the bearing table 1 is a plane with a certain flatness, and the driving assembly 2, the first bearing assembly 3, the second bearing assembly 4, the sliding rod 5 and the adjusting knob 6 are arranged on the bearing surface of the bearing table 1.

The bearing table 1 can be in a rectangular structure, a cylindrical structure and the like. The columnar structure includes, but is not limited to, a polygonal column, and also includes a columnar structure having an irregular cross-sectional shape. In this embodiment, the supporting platform 1 is a rectangular structure, and the top surface of the rectangle is used as a supporting surface, as shown in fig. 1.

In particular, the second carriage assembly 4 is located between the drive assembly 2 and the first carriage assembly 3, as shown in fig. 1. The first bearing component 3 and the second bearing component 4 are used for bearing a first workpiece A and a second workpiece B together, as shown in FIG. 4. The driving assembly 2 is connected to the first carriage assembly 3 to drive the first carriage assembly 3 to move toward or away from the second carriage assembly 4, as shown in fig. 1. When the first bearing component 3 moves towards the direction close to the second bearing component 4, the first workpiece A and the second workpiece B are pressed to enable the first workpiece A and the second workpiece B to move relatively, so that the workpiece component C assembled by the first workpiece A and the second workpiece B can reach the preset size H.

Wherein the first bearing component 3 comprises a first bearing groove 31 with an opening facing the second bearing component 4, the second bearing component 4 comprises a second bearing groove 41 with an opening facing the first bearing component 3, and the opening of the first bearing groove 31 and the opening of the second bearing groove 41 are oppositely arranged, as shown in fig. 1. The first bearing groove 31 and the second bearing groove 41 are formed by sinking downwards from the top of the first bearing component 3 and the top of the second bearing component 4, and the first workpiece a and the second workpiece B are put into the first bearing groove 31 and the second bearing groove 41 from the upper part of the first bearing groove 31 and the second bearing groove 41.

In this embodiment, the first workpiece a and the second workpiece B are pre-assembled by human and then placed in the first bearing groove 31 and the second bearing groove 41, the outer side of the second workpiece B is close to the second bearing groove 41, and the first workpiece a is close to the first bearing groove 31, as shown in fig. 1 and 4. The driving assembly 2 drives the first bearing assembly 3 to move towards the direction of approaching the second bearing assembly 4, so that the first bearing groove 31 and the second bearing groove 41 approach each other, and the first workpiece A and the second workpiece B which are pre-assembled are extruded to move towards the preset dimension H relatively, and therefore accurate assembly is achieved.

In this embodiment, the sum of the length of the first bearing slot 31 and the length of the second bearing slot 41 is less than or equal to the predetermined dimension H, so that the two relatively distant side surfaces of the first bearing slot 31 and the second bearing slot 41 can press the first workpiece a and the second workpiece B to the predetermined dimension H after the first bearing assembly 3 moves towards the second bearing assembly 4. Preferably, the sum of the length of the first bearing groove 31 and the length of the second bearing groove 41 is smaller than the predetermined dimension H, whereby the mounting accuracy and the like of the first bearing assembly 3 and the second bearing assembly 4 can be reduced.

Thereby, the first bearing groove 31 forms a step on which the outer side surface of the first workpiece a can abut, thereby applying the pressing force to the first workpiece a when the first bearing groove 31 moves relatively close to the second bearing groove 41. Further, the opening of the first carrying groove 31 on the side away from the second carrying groove 41 is used for the cable of the second workpiece B to pass through, i.e. the width of the opening is also larger than the radial dimension of the cable, as shown in fig. 4.

In a preferred embodiment, the first bearing groove 3 may be provided as a stepped through hole. Specifically, the first bearing slot 31 includes a first through slot 311 and a second through slot 312 which are communicated with each other, the first through slot 311 is close to the second bearing slot 41, and the second through slot 312 is far from the second bearing slot 41, as shown in fig. 7. That is, the width of the first through slot 311 is greater than the width of the first workpiece a, and is used for bearing the first workpiece a. The width of the second through slot 312 is smaller than the width of the first workpiece a and larger than the width of the cable, so that the cable can pass through and carry the cable. The sum of the length of the first through groove 311 and the length of the second bearing groove 41 is smaller than or equal to the predetermined dimension H, and the step formed by the first through groove 311 and the second through groove 312 is used for extruding the first workpiece a.

Specifically, the second bearing groove 41 includes a first portion 411 and a second portion 412 which are communicated, and the second portion 412 is located between the first portion 411 and the first bearing groove 31, as shown in fig. 2. Further, the width of the first portion 411 is larger than that of the second workpiece B, so as to bear and place the second workpiece B. The second portion 412 has a width greater than the width of the first workpiece a for receiving a portion of the first workpiece a.

In this embodiment, the length of the second portion 412 and the length of the first bearing groove 31 (which may also be the first through groove 311) are greater than the length of the first workpiece a, so that the problem that the step formed by the first workpiece a abutting against the first portion 411 and the second portion 412 during the moving process affects the precise assembly of the first workpiece a and the second workpiece B can be avoided.

In a preferred embodiment, the width of the first portion 411 is slightly larger than that of the second workpiece B, and the width of the first bearing groove 31 (the first through groove 311) is slightly larger than that of the first workpiece a, so that the influence of the displacement of the first workpiece a and the second workpiece B in the width direction during the mutual pressing process on the assembly precision can be avoided.

In the present application, the width of the first bearing groove 31 and the width of the second portion 412 of the second bearing groove 41 can be adjusted according to the width of the first workpiece a. The width of the first portion 411 may be adjusted accordingly to the width of the different second workpieces B. The sum of the lengths of the first bearing groove 31 (the first through groove 311) and the second bearing groove 41 can be adjusted accordingly according to the difference of the predetermined dimension H of the workpiece assembly C.

The driving component 2 is controlled to simultaneously drive the first bearing component 3 and the sliding rod 5 to move towards the side close to the driving component 2 and move to the stop position when the sliding rod 5 is abutted with the adjusting knob 6. When the workpiece assembly C is stopped, the first bearing grooves 31 of the first bearing assemblies 3 and the second bearing grooves 41 of the second bearing assemblies 4 are close to each other and pressed, so that the first workpieces A and the second workpieces B of the workpiece assemblies C are relatively moved to a preset size H. That is, when assembling the first workpiece a and the second workpiece B, the driving assembly 2 is controlled to drive the sliding rod 5 to move to abut against the adjusting knob 6, so that the first workpiece a and the second workpiece B can be accurately assembled to have the predetermined dimension H.

Preferably, the driving assembly 2 is a linear cylinder, so that the size is small and the installation is simple and convenient.

Preferably, the second carriage assembly 4 comprises a first moving through hole 42, and a penetrating direction of the first moving through hole 42 is parallel to a driving direction of the driving assembly 2, as shown in fig. 2.
