Description
Technical Field
[0001] This utility model relates to the field of assembly table technology, and in particular to an assembly table structure with a quick workpiece replacement function. Background Technology
[0002] In today's highly developed fields of mechanical manufacturing and automation, the production of various large-scale mechanical equipment and complex components has become a key force driving industrial development. In these massive and precise manufacturing operations, in order to successfully produce large components and complete machines that meet design requirements, a crucial preliminary process is the precise and efficient assembly of numerous disparate workpieces.
[0003] In current assembly techniques, workers typically use hand tools or their bare hands to pick up the workpieces and assemble, connect, or integrate them according to predetermined design requirements and processes. However, because workpiece assembly requires high precision, manual hand assembly inevitably introduces errors and the risk of misalignment. This is not only time-consuming and labor-intensive but may also increase the probability of workpiece damage, directly affecting the overall quality of the workpiece. Utility Model Content
[0004] The purpose of this invention is to solve the problems of errors and assembly misalignment risks that inevitably exist in the manual hand assembly process in the prior art, and to propose an assembly table structure with a quick workpiece replacement function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An assembly table structure with a quick workpiece replacement function includes a main table, on which a rotating rod is rotatably connected, and a turntable is fixedly connected to one end of the rotating rod. A pair of clamping plates for clamping workpieces are provided on the turntable.
[0007] Also includes:
[0008] Drive component one, the drive component one being used to drive the rotating rod to rotate;
[0009] Drive component two, which is used to drive the two clamping plates to move synchronously;
[0010] The second drive assembly includes a pair of connecting ears fixedly connected to the vertical sidewall of the turntable away from the rotating rod. The same bidirectional lead screw is rotatably connected to the two connecting ears on opposite sidewalls. Both clamping plates are threadedly connected to the bidirectional lead screw. One end of the bidirectional lead screw extends to the side of the connecting ear away from the clamping plate and is fixedly connected to a screwing block that is easy for the operator to turn.
[0011] The connecting lug is provided with a limiting member for fixing the bidirectional lead screw;
[0012] The limiting member includes a mounting base fixedly connected to the connecting ear, and one end of the bidirectional lead screw away from the screw block extends into the mounting base. A set screw is threaded onto the mounting base, and one end of the set screw is in contact with the bidirectional lead screw.
[0013] The turntable has a limiting groove on its vertical sidewall, and the clamping plate and the limiting groove are horizontally slidably connected.
[0014] Preferably, the drive assembly includes a pair of connecting plates fixedly connected to the vertical sidewall of the main platform away from the turntable, the two connecting plates are rotatably connected to the same worm gear on opposite sidewalls, and a worm wheel is fixedly sleeved at the end of the rotating rod away from the turntable, the worm wheel and the worm gear meshing.
[0015] Preferably, one end of the worm extends to the side of the connecting plate away from the worm wheel and is fixedly connected to a rocker wheel.
[0016] Compared with the prior art, the advantages of this utility model are as follows:
[0017] With the inclusion of drive component one and drive component two, the operator only needs to rotate the screw block to drive the bidirectional lead screw to rotate, fixing the workpiece to be assembled on opposite sides of the two clamping plates. At the same time, the operator can flexibly rotate the turntable according to the actual assembly requirements, and the workpiece that can be quickly disassembled is accurately assembled. This reduces the assembly error caused by the positional deviation of manual hand operation, meets the needs of different assembly parts of the workpiece, and improves the flexibility of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-3 An assembly table structure with a quick workpiece replacement function includes a main table 1. The main table 1 serves as the foundational support component of the entire assembly table, providing a stable working plane and ensuring the smooth operation of other components during assembly, thus laying a solid foundation for high-precision assembly. A rotating rod 2 is rotatably connected to the main table 1. The rotating rod 2 provides a crucial power transmission path for subsequent transmission and operation, allowing the workpiece to be flexibly rotated to a suitable assembly position for convenient operator work. A turntable 3 is fixedly connected to one end of the rotating rod 2. The turntable 3 provides a rotatable operating platform for workpiece placement and positioning. During assembly, the operator can easily rotate the turntable 3 according to actual needs, thereby adjusting the angle of the workpiece and facilitating omnidirectional assembly operations. A pair of clamping plates 4 are provided on the turntable 3 for holding the workpiece. Through the tight cooperation of the clamping plates 4, the workpiece can be securely fixed in a specific position, preventing displacement or shaking during assembly, ensuring not only assembly accuracy but also improving assembly safety.
[0025] Also includes:
[0026] Drive component one, which is used to drive the rotating rod 2 to rotate;
[0027] Drive component two is used to drive the two clamping plates 4 to move synchronously.
[0028] The drive assembly includes a pair of connecting plates 31 fixedly connected to the vertical sidewall of the main platform 1 away from the turntable 3. The two connecting plates 31 are rotatably connected to the same worm gear 32 on their opposite sidewalls. A worm wheel 33 is fixedly fitted onto the end of the rotating rod 2 away from the turntable 3, and the worm wheel 33 meshes with the worm gear 32. The worm gear 32 and worm wheel 33 transmission mechanism has advantages such as strong self-locking, large transmission ratio, and smooth transmission. In actual operation, when the operator rotates the worm gear 32 via the rocker wheel 34, the worm wheel 33 will rotate accordingly, thereby driving the rotating rod 2 to achieve precise rotation. This transmission method not only ensures the rotational accuracy of the rotating rod 2 driving the turntable 3, but also maintains stable transmission performance under different working conditions, adapting to various complex assembly environments.
[0029] One end of the worm gear 32 extends to the connecting plate 31 on the side away from the worm wheel 33 and is fixedly connected to a rocker wheel 34. The size and shape of the rocker wheel 34 are designed in accordance with ergonomic principles, making it comfortable for operators to hold and easy and quick to operate, effectively reducing the labor intensity of operators and improving work efficiency.
[0030] The second drive assembly includes a pair of connecting ears 41 fixedly connected to the vertical sidewall of the turntable 3 away from the rotating rod 2. The two connecting ears 41 are rotatably connected to the same bidirectional lead screw 42 on opposite sidewalls. In actual operation, when the operator rotates the bidirectional lead screw 42, the two clamping plates 4 move simultaneously towards or away from each other, thereby quickly clamping or releasing the workpiece, thus achieving rapid workpiece replacement. Both clamping plates 4 are threadedly connected to the bidirectional lead screw 42. One end of the bidirectional lead screw 42 extends to the side of the connecting ears 41 away from the clamping plates 4 and is fixedly connected to a screw block 43 for easy operation. The design of the screw block 43 fully considers the operator's ease of use; its shape and size conform to ergonomic principles, allowing the operator to easily grip and rotate it. The surface of the screw block 43 is provided with an anti-slip texture or coating, further improving operational comfort and safety, and preventing hand slippage during rotation.
[0031] The connecting ear 41 is provided with a limiting member for fixing the bidirectional lead screw 42.
[0032] The limiting component includes a mounting base 44 fixedly connected to the connecting ear 41. The end of the bidirectional lead screw 42 away from the tightening block 43 extends into the mounting base 44. A set screw 45 is threaded onto the mounting base 44, and one end of the set screw 45 contacts the bidirectional lead screw 42. By tightening the set screw 45, after the clamping plate 4 stably clamps the workpiece, the bidirectional lead screw 42 is firmly fixed in the mounting base 44, preventing the bidirectional lead screw 42 from rotating and causing the clamping to loosen, thus ensuring the positional stability of the bidirectional lead screw 42.
[0033] The turntable 3 has a limiting groove 46 on its vertical side wall, and the clamping plate 4 and the limiting groove 46 are horizontally slidably connected. The setting of the limiting groove 46 further restricts the movement trajectory of the clamping plate 4, so that the clamping plate 4 can only move in the horizontal direction within the limiting groove 46. This design can effectively prevent the clamping plate 4 from deviating or tilting during movement, and ensure the movement accuracy and stability of the clamping plate 4.
[0034] The functional principle of this utility model can be explained through the following operation methods:
[0035] First, the workpiece to be processed is placed in the central area of the turntable 3. The operator rotates the screw block 43, which drives the bidirectional lead screw 42 to rotate. Since the two clamping plates 4 are connected to the two ends of the bidirectional lead screw 42 by threads, the reverse thread structure causes the two clamping plates 4 to slide synchronously towards the center in the limiting groove 46 until the workpiece is stably clamped.
[0036] Then tighten the set screw 45 on the mounting base 44 so that its end presses against the extension end of the bidirectional lead screw 42, and lock the position of the lead screw by friction to ensure stable clamping.
[0037] When the workpiece assembly angle needs to be adjusted, the operator holds the rocker wheel 34 and rotates it. Through the meshing transmission of the worm gear 32 and worm wheel 33, the rotating rod 2 and the turntable 3 are rotated as a whole. The unique self-locking characteristic of the worm gear 32 and worm wheel 33 can maintain positioning at any angle without the need for an additional braking device.
[0038] During the rotation of the turntable 3, the clamping plate 4 rotates synchronously with the turntable 3, and the limiting groove 46 always provides horizontal sliding guidance for the clamping plate 4.
[0039] After assembly, first loosen the set screw 45 to release the lock of the bidirectional lead screw 42, then rotate the screw block 43 to move the clamping plate 4 outwards synchronously to release the workpiece. At this point, the machined workpiece can be quickly removed, and a new workpiece can be replaced to repeat the clamping operation.
[0040] The entire device achieves precise angle adjustment through worm gear 33 and worm 32 transmission. The bidirectional lead screw 42 structure ensures symmetrical clamping force. With the guiding constraint of the limiting groove 46, the workpiece replacement process can be completed quickly.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
