Description

Technical Field

[0001] This invention belongs to the field of workpiece assembly technology, specifically relating to a rotating structure and a semi-automatic assembly fixture. Background Technology

[0002] For workpiece assembly, manual operation is mostly used, where one product is inserted into another and then pressed tightly. However, this method is prone to problems such as improper assembly, unevenness, and is labor-intensive, time-consuming, and has low productivity and yield.

[0003] In existing technologies, there are devices that use a rotating structure to move workpieces sequentially through different workstations to perform different processes. These devices mostly use a drive motor to rotate a turntable, and employ cams, irregular gears, and other structures to achieve intermittent rotation of the turntable. This allows the turntable to stop rotating when it moves the workpiece to different workstations, facilitating the completion of the corresponding processes at each workstation. However, the design of this intermittently rotating turntable structure is relatively complex. The cam and gears require transmission through a chain mechanism, resulting in numerous structural components and making maintenance and repair inconvenient. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a semi-automatic assembly fixture. Through the structural design of the drive mechanism, the resistance mechanism and the rotating table, the rotating table can rotate intermittently, thereby driving the workpieces on the rotating table to pass through different workstations in sequence to complete different processes.

[0005] First, a rotating structure is proposed, including a driving mechanism, a resistance mechanism, and a rotating platform. The driving mechanism includes a push block and a telescopic cylinder. The push block is driven by the telescopic cylinder to reciprocate. The resistance mechanism includes a locking block and a spring rod. The rotating platform is equipped with a second locking slot adapted to the push block and a first locking slot adapted to the locking block. Multiple first and second locking slots are provided, arranged in a circumferential array on the rotating platform, and adjacent to each other. When the push block moves forward driven by the telescopic cylinder, the locking structure between the push block and the second locking slot provides a push to the rotating platform. The force drives the rotating platform to complete one rotation. When the push block retracts with the telescopic cylinder, it engages and positions the rotating platform through the meshing action of the locking block and the locking slot. When the push block is driven forward again by the telescopic cylinder to rotate the rotating platform, the spring rod is pushed by the rotating platform and causes the locking block to retract. During the rotation of the rotating platform driven by the push block, the locking block sequentially enters the next locking slot. After the rotating platform completes this rotation, it engages and positions the rotating platform again. Through the coordinated action of the drive mechanism and the resistance mechanism, the reciprocating movement of the push block is used to achieve the interval rotation of the rotating platform.

[0006] Preferably, the rotating table includes a disc and a rotating shaft. The disc has a loading groove for loading workpieces. The disc is rotatably connected to the worktable via the rotating shaft. The first slot and the second slot are configured on the disc.

[0007] Preferably, the drive mechanism further includes a slide plate, an auxiliary plate, and a bracket. The telescopic cylinder is mounted on the side of the rotating table via the bracket. The telescopic end of the telescopic cylinder is connected to the slide plate. A push block is mounted on the slide plate. The slide plate is driven by the telescopic cylinder to move back and forth on the auxiliary plate, which is mounted on the worktable.

[0008] Preferably, the resistance mechanism further includes a stop block and a sliding block. The stop block is mounted on the worktable, and the sliding block is connected to the stop block by a spring rod. A locking block is installed at the other end of the sliding block.

[0009] Preferably, the locking block is connected to the sliding block via a support rod, and the locking block is cylindrical, with the outer wall of the cylindrical locking block in contact with the side wall of the rotating table.

[0010] A semi-automatic assembly fixture includes the aforementioned rotating structure, and further includes a feeding mechanism, a limiting component, a baffle, and a guide plate. The feeding mechanism is installed below the rotating table, the limiting component is mounted above the rotating table, the guide plate is disposed beside the rotating table, the top of the guide plate is inclined, and the baffle is installed on both sides of the guide plate. The two baffles, the guide plate, and the limiting component enclose a limiting space. After the feeding mechanism pushes the workpiece loaded on the rotating table upward, the workpiece moves upward into the limiting space and is driven by the limiting component to tilt towards the guide plate, and slides down to a fixed point through the limiting action of the guide plate and the baffle.

[0011] Preferably, the unloading mechanism includes a lifting cylinder and a push rod, wherein the push rod is installed on the telescopic end of the lifting cylinder and moves up and down reciprocally as the lifting cylinder extends and retracts.

[0012] Preferably, the limiting component includes a connecting plate and a limiting plate. The limiting plate is mounted above the rotating table by connecting the connecting plate to the mounting frame. The side of the limiting plate facing the workpiece includes a first inclined surface and a second inclined surface. The first inclined surface serves as the top wall of the limiting plate, and the second inclined surface serves as the side wall of the limiting plate. When the workpiece moves upward to the first inclined surface, it is driven by the first and second inclined surfaces to tilt away from the rotating table.

[0013] Preferably, it also includes a pressing mechanism, which includes a pressing cylinder. The pressing cylinder is mounted on the top of the rotating table via a mounting bracket, and the telescopic end of the pressing cylinder is connected to a pressing head for workpiece assembly.

[0014] Preferably, the workpiece includes component one and component two. Component one has a mounting groove on its top for engaging component two. Component one is rod-shaped and has a protrusion. When component one is inserted into the loading groove on the rotating table, it is limited by the protrusion.

[0015] The beneficial effects of this invention are as follows: The rotating structure and semi-automatic assembly fixture, through the structural design of the drive mechanism, resistance mechanism and rotating table, enable the push block to move forward driven by the telescopic cylinder, while the push block and the locking structure of the second slot provide thrust to the rotating table, driving the rotating table to rotate. During this process, the spring rod is pushed by the rotating table and drives the locking block to retract. At the same time, the locking block sequentially enters the next slot one during the rotation of the rotating table, locking and positioning the rotating table after one rotation, thereby realizing the intermittent rotation of the rotating table, so that the rotating table can drive the workpiece loaded on it to pass through different workstations in sequence, thereby completing different processes.

[0016] The unloading mechanism, limiting components, baffles, and guide plates are designed according to the workpiece structure. The limiting components, baffles, and guide plates can form a limiting space, so that when the unloading mechanism pushes the workpiece out of the rotating table, it can tilt due to the structural design of the limiting components, and the workpiece can slide down according to the preset route through the baffles and guide plates, realizing automatic unloading and centralized collection of workpieces.

Detailed Implementation

[0028] Example 1

[0029] like Figure 1 As shown, a semi-automatic assembly fixture includes a pressing mechanism 2, a driving mechanism 3, a resistance mechanism 4, a rotating table 5, a feeding mechanism 6, a limiting component 7, a baffle 8, and a diversion plate 9, all mounted on a workbench 1.

[0030] The drive mechanism 3, the resistance mechanism 4, and the rotating table 5 constitute a rotating structure for driving the workpiece 100 to rotate. The workpiece 100 is loaded on the rotating table 5. The drive mechanism 3 is used to drive the rotating table 5 to rotate, and the resistance mechanism 4 is used to position the rotating table 5, so as to realize the interval rotation of the rotating table 5.

[0031] The workpiece 100 includes component one and component two. Component one has a mounting groove on its top for engaging component two. Component two is placed in the mounting groove of component one to pre-install the workpiece 100. Then, the pressing mechanism 2 assembles component one and component two into place, completing the assembly of the workpiece 100. The assembled workpiece 100 is automatically unloaded by the unloading mechanism 6. In addition, component one is rod-shaped and has a protrusion. When component one is inserted into the loading groove 505 on the rotating table 5, it is limited by the protrusion.

[0032] like Figure 1 As shown, the pressing mechanism 2 and the unloading mechanism 6 are both arranged on the side of the rotating table 5. The pressing mechanism 2 is located above the worktable 1 and is used to press component 2 downward so that component 1 and component 2 fit together to achieve the assembly of workpiece 100. The unloading mechanism 6 is located below the worktable 1 and is used to push the assembled workpiece 100 out of the rotating table 5.

[0033] In addition, in order to limit the path of workpiece 100, the limiting member 7, the baffle 8 and the guide plate 9 are arranged on the side of the unloading mechanism 6. When the workpiece 100 is lifted by the unloading mechanism 6 and moves upward to the limiting member 7, it is tilted by the action of the limiting member 7 and slides down along the guide plate 9 into the collection box, thereby realizing the automatic unloading and centralized collection of workpiece 100.

[0034] For rotating structures, such as Figure 2 , Figure 3 As shown, the rotating table 5 includes a disk 501 and a rotating shaft 504. The disk 501 has a loading groove 505 for loading the workpiece 100. The disk 501 is rotatably connected to the worktable 1 via the rotating shaft 504. The disk 501 has a second slot 503 adapted to the drive mechanism 3 and a first slot 502 adapted to the resistance mechanism 4. Multiple slots 502 and second slots 503 are distributed around the circumference and are arranged adjacent to each other.

[0035] like Figures 2 to 4 As shown, the drive mechanism 3 includes a telescopic cylinder 301, a slide plate 302, a pusher block 303, an auxiliary plate 304, and a bracket 305. The telescopic cylinder 301 is mounted on the side of the rotating table 5 via the bracket 305. The telescopic end of the telescopic cylinder 301 is connected to the slide plate 302. The pusher block 303 is mounted on the slide plate 302. The slide plate 302 is driven by the telescopic cylinder 301 to reciprocate on the auxiliary plate 304, which is mounted on the worktable 1.

[0036] Specifically, the shape of the slot 2 503 is adapted to the structure of the push block 303. When the telescopic cylinder 301 drives the push block 303 on the slide plate 302 to move forward, the push block 303 and the slot 2 503 are used to provide thrust to the rotating table 5, driving the rotating table 5 to rotate.

[0037] Furthermore, the auxiliary plate 304 is L-shaped, with one end of the slide plate 302 mounted on the bend of the auxiliary plate 304. This L-shaped design allows the horizontal plate of the auxiliary plate 304 to support the slide plate 302, improving the stability of the slide plate 302's movement, and allows the vertical plate of the auxiliary plate 304 to abut against the slide plate 302, maintaining the axial stability of the telescopic cylinder 301.

[0038] like Figure 2 , Figure 3 As shown, the resistance mechanism 4 includes a stop block 401, a spring rod 402, a sliding block 403, and a locking block 404. The stop block 401 is mounted on the worktable 1, and the stop block 401 is connected to the sliding block 403 through the spring rod 402. The locking block 404 is mounted on the other end of the sliding block 403.

[0039] Furthermore, the locking block 404 is connected to the sliding block 403 via a support rod. The locking block 404 is cylindrical, and the outer wall of the cylindrical locking block 404 contacts the side wall of the rotating table 5. Through the cylindrical structural design, the locking block 404 will not obstruct the rotation of the rotating table 5.

[0040] Specifically, the shape of the slot 502 is adapted to the structure of the locking block 404. When the drive mechanism 3 finishes driving the disc 501, the locking block 404 engages with the slot 502, thereby engaging the resistance mechanism 4 with the rotating table 5 and positioning the rotating table 5.

[0041] When the drive mechanism 3 drives the disc 501 to move again, the spring rod 402 is pushed by the rotating table 5 and drives the locking block 404 to move backward, canceling the resistance of the locking block 404 on the rotating table 5. In addition, during the process of the rotating table 5 completing one rotation driven by the push block 303, the locking block 404 sequentially enters the next slot 502, and after the rotating table 5 completes this rotation, it locks and positions the rotating table 5 again.

[0042] Through the cooperation of the drive mechanism 3, the rotating table 5, and the resistance mechanism 4, the rotating table 5 can rotate at intervals, facilitating the operation of the pressing mechanism 2 and the feeding mechanism 6. Furthermore, the rotation speed of the rotating table 5 can be adjusted by regulating the speed of the telescopic cylinder 301.

[0043] It should be noted that the inner diameter of the second slot 503 is smaller than the inner diameter of the snap-fit ​​block 404, so that the snap-fit ​​block 404 will not fall into the second slot 503 when it passes through the second slot 503, and the snap-fit ​​block 404 can pass through the second slot 503 smoothly and snap into the first slot 502.

[0044] On the other hand, such as Figure 1 , Figure 5 , Figure 6 As shown, the unloading mechanism 6 includes a lifting cylinder 601 and a push rod 602. The push rod 602 is installed on the telescopic end of the lifting cylinder 601 and moves up and down reciprocally with the telescopic movement of the lifting cylinder 601. When the push rod 602 moves upward, it can push the assembled workpiece 100 at the corresponding position in the rotating table 5 upward.

[0045] like Figure 6 , Figure 9 As shown, the limiting member 7 includes a connecting plate 701 and a limiting plate 702. The connecting plate 701 is connected to the mounting bracket 202, and the limiting plate 702 is mounted above the rotating table 5 to limit the position of the upward ejected workpiece 100.

[0046] Please refer to the following carefully. Figure 9The limiting plate 702 facing the workpiece 100 includes a first inclined surface 703 and a second inclined surface 704. The first inclined surface 703 serves as the top wall of the limiting plate 702, and the second inclined surface 704 serves as the side wall of the limiting plate 702. When the workpiece 100 moves upward to the first inclined surface 703, it is driven by the first inclined surface 703 and the second inclined surface 704 to tilt away from the rotating table 5.

[0047] To ensure that the workpiece 100 can accurately slide into the collection box next to the workbench 1, a guide plate 9 is also installed on the workbench 1. The top of the guide plate 9 is inclined so that the tilted workpiece 100 can slide along the inclined direction of the guide plate 9. In addition, baffles 8 are provided on both sides of the guide plate 9 to further limit the movement path of the workpiece 100.

[0048] The two baffles 8, the guide plate 9, and the limiting member 7 form a limiting space. Therefore, after the unloading mechanism 6 pushes the workpiece 100 loaded on the rotating table 5 upward, the workpiece 100 moves upward into the limiting space and is driven by the limiting member 7 to tilt towards the guide plate 9. It then slides down to a fixed point through the limiting action of the guide plate 9 and the baffles 8.

[0049] like Figure 7 , Figure 8 As shown, the pressing mechanism 2 includes a pressing cylinder 201, which is mounted on the top of the rotating table 5 via a mounting bracket 202. The telescopic end of the pressing cylinder 201 is connected to a pressing head for assembling the workpiece 100.

[0050] Working principle: When using this semi-automatic assembly fixture, the operator places component two into the mounting slot of component one to form a pre-installation structure for workpiece 100, and then places workpiece 100 into the loading slot 505 of the rotating table 5.

[0051] The drive mechanism 3 is activated, and the push block 303 is driven to reciprocate through the telescopic cylinder 301. When the push block 303 moves forward with the telescopic cylinder 301, it can drive the rotating table 5 to rotate. When the push block 303 moves backward with the telescopic cylinder 301, the rotating table 5 loses the thrust of the push block 303 and stops due to the meshing action between the locking block 404 of the resistance mechanism 4 and the locking groove 502 of the rotating table 5. When the push block 303 moves forward again with the telescopic cylinder 301 and drives the rotating table 5 to rotate, the locking block 404 retracts due to the elastic action of the spring rod 402 and sequentially enters the next locking groove 502 during the rotation of the rotating table 5 to achieve the locking and positioning of the rotating table 5.

[0052] Repeat the above actions. Through the action of the drive mechanism 3 and the resistance mechanism 4, the rotating table 5 can drive the workpiece 100 on it to rotate at intervals. The workpiece 100 passes through the pressing mechanism 2 and the unloading mechanism 6 in sequence. The pressing mechanism 2 uses the rotation interval to assemble component one and component two into place. The unloading mechanism 6 uses the rotation interval to push out the assembled workpiece 100, thereby realizing the automatic unloading of the workpiece 100.

[0053] Specifically, when workpiece 100 passes through pressing mechanism 2, pressing cylinder 201 drives pressing head downward, and the downward pressure of pressing head completely engages component one and component two, realizing the assembly of workpiece 100. When the assembled workpiece 100 passes through unloading mechanism 6, lifting cylinder 601 drives lifting rod 602 upward, pushing workpiece 100 out of the rotating table 5 at the corresponding position. When workpiece 100 moves upward to limit member 7, the combined action of inclined surface one 703 and inclined surface two 704 causes workpiece 100 to tilt and slide down along the inclined end of guide plate 9 into collection box, realizing automatic unloading of workpiece 100.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
