Description

Technical Field

[0001] This invention belongs to the field of assembly tooling technology, and in particular relates to a synchronous assembly device for a T-shaped double-back bracket and a transverse plastic shell. Background Technology

[0002] The assembly of the T-shaped double-back bracket and the transverse plastic shell typically involves a step-by-step manual or semi-automated process. First, the support beam needs to be welded and fixed to the bracket composed of components such as folded rods to form the T-shaped double-back bracket. Then, the entire assembly needs to be flipped over, and the back of the bracket installed against the plastic shell and secured with bolts. This traditional assembly method has several major problems:

[0003] The process is cumbersome and inefficient: welding and bolting are carried out in separate steps, involving operations such as flipping and repositioning of workpieces, resulting in a long production cycle and low overall assembly efficiency.

[0004] Positioning accuracy is difficult to guarantee: In multi-step operations, the workpiece needs to be clamped and moved multiple times, which can easily lead to cumulative errors. This may result in inaccurate welding positions between the support beam and the bracket, or misalignment of the connection holes between the plastic shell and the support beam, affecting product quality and consistency. Summary of the Invention

[0005] The purpose of this invention is to provide a synchronous assembly device for a T-shaped double-back bracket and a transverse plastic shell. By improving the setting of the first clamping mechanism and the second clamping mechanism, the problem of multiple clamping and moving of workpieces in the existing assembly process is solved.

A countersunk hole is provided on the back of the plastic shell, and bolts passing through the countersunk hole are used to fix it to the supporting beam.

[0012] Furthermore, the inner wall surface of the first clamping beam is provided with a clamping groove for clamping the folded rod.

[0013] Furthermore, it also includes a side upright plate and a first clamping structure and a second clamping structure mounted on the side upright plate, the second clamping structure being located below the first clamping structure; a pair of vertical guide rails are provided on one side of the side upright plate, the first clamping structure and the second clamping structure have the same structure, both including a box for inserting a mounting plate, and an electric slider that cooperates with the guide rail is provided on the outer wall of the box.

[0037] Among them, such as Figure 1-6 The first clamping mechanism includes a U-shaped frame 4 with a rotating shaft 43 connected to one end. The two opposite inner walls of the U-shaped frame 4 are connected to first clamping beams 42 through first telescopic modules 41.

There are two of each type of two-axis structure and two clamping beams 52, which are arranged opposite each other. Each end face of the second clamping beam 52 has a mounting cavity 521, within which a second telescopic module 522 is fixed. Each end face of the second clamping beam 52 also has at least one guide hole 526. One side of the positioning clamping plate 53 is connected to a guide rod 531 that mates with the guide hole 526. The two second clamping beams... Each of the two inner walls of the support plate 52 is provided with a protruding support plate 520. The support plate 520 is provided with two clamping structures that clamp the sides of the two ends of the support beam 2. The clamping structure includes a pair of clamping blocks 54 and a rectangular hole 523 opened on the support plate 520. The top of the clamping block 54 is provided with a guide slope 541, and the bottom of the clamping block 54 is provided with an "I"-shaped slider 542. The "I"-shaped slider 542 is installed in the rectangular hole 523 and can move along the length of the rectangular hole 523. The bottom side of the support plate 520 located at both ends of the rectangular hole 523 is provided with a side plate 524.

A clamping plate is connected to one inner wall of the box through several fourth telescopic modules. The opening end of the box of the first clamping structure 61 faces downward, and the opening end of the box of the second clamping structure 62 faces upward.

[0040] Assembly steps include:

[0041] The mounting plate 12 of the control bracket is inserted downward into the second clamping structure 62, which controls the first telescopic module 41 of the first clamping mechanism to move, driving the two first clamping beams 42 to move towards each other, and firmly clamping the two folded rods 1 through the clamping groove;

[0042] The support beam 2 is placed on the support plate 520 of the two second clamping beams 52, and the end of the support beam 2 slides in along the guide slope 541 of the clamping block 54; then, the two third telescopic modules 525 are activated, driving the two pairs of clamping blocks 54 to move towards each other, and tightly clamping the end of the support beam 2 from both sides.

[0043] The lifting cylinder 50 is extended, which drives the support beam 2 to move upward first. After the L-shaped connecting plate 21 passes through the gap between the two folded rods 1, the third telescopic module 525 drives the two support beams 2 to move horizontally, causing the L-shaped connecting plate 21 to slide into the corresponding connecting rod 11. The L-shaped connecting plate 21 can be welded to the connecting rod 11 using welding machine or other equipment.

[0044] Control the second clamping structure 62 to move downward along the length of the guide rail 60, at which time the mounting plate 12 disengages from the second clamping structure 62; control the drive structure to rotate the U-shaped frame 4 180°, at which time the mounting plate 12 faces upward; control the second clamping structure 62 and the first clamping structure 61 to move upward and downward along the length of the guide rail 60 respectively, the mounting plate 12 is inserted into the first clamping structure 61, and at this time the top surface of the second clamping structure 62 abuts against the two folded rods 1;

[0045] The lifting cylinder 50 extends, causing the support beam 2 to move upwards first. The operator or robot places the back plastic shell 3 on the support plate 520 of the two second clamping beams 52. Then, the second telescopic module 522 moves, pushing the positioning clamp 53 to move and clamp the back plastic shell 3 from both sides. The back plastic shell 3 rests against the positioning clamp 53 and the clamping block 54. The operator uses an electric screwdriver to pass the bolt through the countersunk hole 31 on the back plastic shell 3 and screw it into the threaded hole of the support beam 2 to complete the fixation of the back plastic shell 3.

[0046] The first clamping mechanism and the second clamping mechanism are controlled to loosen synchronously. The second clamping structure 62 and the first clamping structure 61 are controlled to move downward along the length of the guide rail 60 to the corresponding height. After the operator supports the backrest, the first clamping structure 61 is controlled to move upward along the length of the guide rail 60. At this time, the operator can control the backrest to be removed from the second clamping structure 62.

[0047] It also includes a controller, which is connected to the electric slider, the fourth telescopic module, the first clamping mechanism, and the second clamping mechanism. Sensors for detecting whether the clamping action is in place are provided on the two clamping surfaces of the clamping block 54, the inner wall of the second clamping beam 52, the inner wall of the clamping groove, the inner wall of the clamping plate, the inner wall of the positioning clamping plate 53, and the upper surface of the support plate 520.
