Technical Field

[0001] This utility model relates to an assembly device, and more particularly to an assembly device for a weight adjustment component for dumbbells. Background Technology

[0002] The weight adjustment assembly for dumbbells is composed of multiple parts. After assembly, the parts need to be fixed by workers using screws. To ensure processing efficiency, screw tightening devices are usually used when tightening the screws.

[0003] However, in the existing screw tightening device, when processing the weight adjustment components for dumbbells of different sizes, it is necessary to change the fixtures of different sizes used to clamp the weight adjustment components. However, changing the fixtures is not only complicated, but also requires specialized technicians to complete the operation. This will not only reduce the production efficiency of the weight adjustment components for dumbbells, but also increase the production cost of the weight adjustment components for dumbbells. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an assembly device for a dumbbell counterweight adjustment component that facilitates the replacement of fixtures.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: An assembly device for a dumbbell counterweight adjustment component, comprising a workbench and a fixture assembly and a mounting bracket mounted on the workbench. The mounting bracket is provided with a first moving component, and a tightening component is provided on the first moving component. The fixture assembly includes: a second moving component mounted on the workbench, a mounting plate mounted on the second moving component, and the second moving component controlling the reciprocating movement of the mounting plate on the workbench; and a first slide rail, of which at least two are provided, the two first slide rails being longitudinally and symmetrically mounted on the mounting bracket. At the top of the mounting plate, two first slide blocks are slidably mounted on the first slide rail, and each first slide block is provided with bolts connecting to the first slide rail; there are at least two support plates, which are horizontally mounted on the first slide rail, and the two ends of the support plates are detachably connected to the first slide blocks by bolts; the top of the support plates is evenly provided with multiple connection holes; the placement platform is mounted on the support plate, and the bottom of the placement platform is provided with connecting posts that are inserted into the connection holes; the top of the placement platform is evenly provided with multiple placement slots for placing the weight adjustment components for dumbbells.

[0006] A further preferred embodiment of this utility model is as follows: the second moving component includes a second slide rail, and there are at least two second slide rails. The two second slide rails are longitudinally and symmetrically installed on the top of the worktable. Two second slide blocks are slidably arranged on each of the second slide rails. The top of the second slide blocks is connected to the bottom of the mounting plate. A telescopic device is longitudinally installed on the worktable. The telescopic device is located between the second slide rails. The telescopic end of the telescopic device is provided with a connecting plate. The connecting plate is connected to the bottom of the mounting plate.

[0007] A further preferred embodiment of this utility model is that elastic abutment blocks are provided on the walls of the placement groove.

[0008] A further preferred embodiment of this utility model is: the first slide rail is detachably mounted on the mounting plate by bolts, and a limiting block is provided at each end of the first slide rail.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0017] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0018] This embodiment mainly describes the structure of the assembly equipment for the weight adjustment component of dumbbells, as follows: like Figures 1-10As shown, the assembly equipment for a dumbbell weight adjustment component includes a workbench 1, a fixture assembly 2 mounted on the workbench 1, and a mounting bracket 3. The fixture assembly 2 is used to place the dumbbell weight adjustment component 8 to be assembled with screws. The mounting bracket 3 is equipped with a first moving assembly 4 (including a longitudinal guide mechanism 41 and a transverse guide mechanism 42), and a tightening assembly 5 (including a lifting mechanism 52 and a tightening mechanism 51, the lifting mechanism 52 being used to control the up-and-down reciprocating movement of the tightening mechanism 51) is provided on the first moving assembly 4 for tightening screws. The tightening assembly 5 is located above the fixture assembly 2, and the first moving assembly 4... The tightening assembly 5 is used to control the reciprocating movement of the tightening assembly 5 above the fixture assembly 2. When assembling the dumbbell counterweight adjustment assembly 8, first place the screw to be tightened into the mounting hole 81 on the dumbbell counterweight adjustment assembly 8, then place the dumbbell counterweight adjustment assembly 8 into the fixture assembly 2, then activate the first moving assembly 4 to control the tightening mechanism 51 in the tightening assembly 5 to move above the screw, then activate the lifting mechanism 52 to control the tightening mechanism 51 to move toward the screw until the working end of the tightening mechanism 51 engages with the top of the screw, then activate the tightening mechanism 51 to tighten the screw. The fixture assembly 2 includes a second moving assembly 21 mounted on the worktable 1, and a mounting plate 22 is provided on the second moving assembly 21. The second moving assembly 21 is used to control the reciprocating movement of the mounting plate 22 on the worktable 1. At least two first slide rails 23 are longitudinally and symmetrically arranged on the top of the mounting plate 22. Two first slide blocks 231 are slidably arranged on each of the two first slide rails 23, and each first slide block 231 is provided with a bolt connected to the first slide rail 23. Thus, the first slide blocks 231 can be positioned on the first slide rails 23, and then... Two bearing plates 25 are horizontally arranged on the rail 23. The left and right ends of the bearing plates 25 are detachably connected to the first slide blocks 231 on the two first slide rails 23 by bolts. Multiple connecting holes 251 are evenly opened on the top of the bearing plates 25. Finally, a placement platform 24 is set on the top of the bearing plates 25, and a connecting post 243 that is inserted into the connecting holes 251 is set at the bottom of the placement platform 24. This ensures the stability of the placement platform 24 on the bearing plates 25. Multiple placement slots 241 for placing the dumbbell counterweight adjustment component 8 are evenly opened on the top of the placement platform 24. When the dumbbell weight adjustment component 8 to be processed is placed into the fixture component 2, the second moving component 21 is first activated, causing the second moving component 21 to control the mounting plate 22, together with the first slide rail 23, the first slide block 231, the support plate 25 and the placement table 24 mounted on the mounting plate 22, to move towards the front end on the worktable 1. This makes it easier for the operator to place the dumbbell weight adjustment component 8 to be processed into the placement slot 241 on the placement table 24. After the dumbbell weight adjustment component 8 is placed, the second moving component 21 is activated again, causing the first slide rail 23, the first slide block 231, the support plate 25 and the placement table 24 mounted on the mounting plate 22 to move towards the rear end on the worktable 1, so that the placement table 24 is located below the tightening component 5. This makes it easier for the tightening component 5 to process the dumbbell weight adjustment component 8 on the placement table 24. When processing the weight adjustment assembly 8 for dumbbells of different sizes, only the corresponding size of the placement platform 24 needs to be replaced. When replacing the placement platform 24, simply remove the original placement platform 24 from the support plate 25 and then place the placement platform 24 to be replaced onto the support plate 25. This simplifies the fixture replacement steps and reduces the requirements for operators when replacing fixtures. This not only improves the production efficiency of the weight adjustment assembly 8 for dumbbells but also reduces the production cost of the weight adjustment assembly 8 for dumbbells. If it is necessary to replace the placement platform 24 with a different width, first remove the placement platform 24, then remove the support plate 25 from the first slide block 231, then remove the bolts connecting the first slide block 231 to the first slide rail 23, and finally control the first slide block 231 to move on the first slide rail 23 so that the distance between the first slide blocks 231 on each first slide rail 23 is smaller than the width of the placement platform 24 to be installed. Then, the first slide block 231 is fixed on the first slide rail 23 with bolts, and then the support plate 25 is reconnected to the first slide block 231 with bolts. Finally, the corresponding placement platform 24 is placed on the support plate 25. This facilitates the installation of placement platforms 24 with different widths, thereby increasing the application range of the fixture assembly 2.

[0019] Furthermore, in order to ensure the stability of the dumbbell weight adjustment component 8 in the placement slot 241, elastic abutment blocks 242 made of elastic rubber are provided on the slot walls of the placement slot 241. In this way, when the dumbbell weight adjustment component 8 is placed in the placement slot 241, the side wall of the dumbbell weight adjustment component 8 can abut against the elastic abutment block 242, thereby ensuring the stability of the dumbbell weight adjustment component 8 in the placement slot 241.

[0020] Furthermore, the first slide rail 23 is detachably mounted on the mounting plate 22 by bolts, which facilitates the disassembly and assembly of the first slide rail 23. At the same time, in order to prevent the first slide block 231 from separating from the first slide rail 23 when the first slide block 231 is moved, a limit block 232 is provided at each end of the first slide rail 23.

[0021] Furthermore, in order to improve the safety of the assembly equipment during operation, baffles 6 are provided on the rear, left and right sides and top of the mounting frame 3. At the same time, in order to facilitate the internal maintenance of the assembly equipment, movable doors 7 are provided on the baffles 6 on the side walls of the mounting frame 3.

[0022] The second moving component 21 includes two longitudinally and symmetrically mounted second slide rails 212 on the top of the worktable 1. Two second slide blocks 213 are slidably mounted on each second slide rail 212, with the top of the second slide block 213 connected to the bottom of the mounting plate 22. A telescopic device 211 is mounted on the worktable 1 between the two slide rails. A connecting plate 214 connected to the bottom of the mounting plate 22 is mounted on the telescopic end of the telescopic device 211. When the second moving component 21 is in operation, the telescopic device 211 is activated. For example, when the telescopic end of the telescopic device 211 extends, the telescopic device 211 can push the mounting plate 22 towards the front end of the worktable 1 via the connecting plate 214. The second slide rails 212 and the second slide blocks 213 ensure the stability of the mounting plate 22 during movement.

[0023] Furthermore, in order to prevent the second slide block 213 from disengaging from the second slide rail 212 when the telescopic device 211 is in operation, the length of the telescopic device 211 when extended is less than the length of the second slide rail 212.
