Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a dual-station clamping device. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. It can be divided into cutting and pressure processing according to the difference in processing methods.

[0003] In the field of machining, for example, the utility model patent with publication number CN207643040U only allows for the fixing of one part at a time during processing. With the continuous expansion of production scale and the increasing demand for product diversification, the processing efficiency of this single-station fixture is low and cannot meet the schedule requirements of mass production. Moreover, its function is relatively limited; for some irregularly shaped parts or parts requiring combined processing, it is difficult to achieve precise positioning and fixing, resulting in difficulty in guaranteeing processing accuracy. Furthermore, the frequent changing of fixtures to adapt to the processing of different parts is cumbersome, not only consuming a lot of time and labor costs but also easily affecting product quality due to operational errors. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a dual-station fixture device, solving the problem that traditional single-station fixtures can only fix one part at a time for processing. With the continuous expansion of production scale and the increasing demand for product diversification, the processing efficiency of such single-station fixtures is low and cannot meet the schedule requirements of mass production. Moreover, its function is relatively limited, making it difficult to accurately position and fix parts with irregular shapes or requiring combination processing, resulting in difficulties in guaranteeing processing accuracy.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dual-station clamping device includes a worktable with two sets of movable clamping mechanisms. Two arc-shaped sliding holes and two central holes are formed through the worktable. Each clamping mechanism includes a clamping seat with a limiting rod fixedly mounted on it. The limiting rod is rotatably installed within the central holes of the worktable. A limiting block is provided at the lower end of the limiting rod and fits against the lower end of the worktable. A guide screw is fixedly mounted on the clamping seat and slidably installed within the arc-shaped sliding holes of the worktable.

[0009] Preferably, a locking nut is threaded through the guide screw and fits against the lower end of the worktable; a fixing clamping block is fixedly installed on the clamping seat; and an L-shaped fixing plate is fixedly installed on the clamping seat.

[0010] Preferably, an adjusting screw is threaded through the L-shaped fixing plate, and a movable clamping block is mounted on the side end of the adjusting screw via a bearing. The movable clamping block is slidably mounted on the clamping seat and is installed correspondingly to the fixed clamping block. The two clamping mechanisms are symmetrical about the center point of the worktable.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this new invention, by setting two sets of movable clamping mechanisms, and the two sets of clamping mechanisms are symmetrical about the center point of the worktable, two parts can be processed simultaneously during actual processing. Compared with traditional single-station fixtures, the workload can be doubled in one processing cycle, which greatly shortens the processing cycle and improves the overall processing efficiency. The two sets of clamping mechanisms can be used in combination or individually.

[0013] In this new invention, the arc-shaped sliding hole and the central hole on the worktable, together with the guide screw and the limiting round rod on the clamping seat, allow the clamping seat to rotate around the limiting round rod as an axis after the locking nut is loosened, so that the guide screw can slide in the arc-shaped sliding hole, realizing multi-angle adjustment of the clamping mechanism. At the same time, the distance between the movable clamping block and the fixed clamping block can be adjusted by rotating the adjusting screw. This makes the fixture adaptable to parts of different shapes and sizes, and can also meet the clamping needs of parts of different sizes, significantly enhancing the applicability of the fixture.

[0020] This application provides a dual-station fixture device, effectively solving the problem that traditional single-station fixtures can only fix one part at a time for processing. With the continuous expansion of production scale and the increasing demand for product diversification, the processing efficiency of such single-station fixtures is low and cannot meet the schedule requirements of mass production. Moreover, its function is relatively limited, making it difficult to accurately position and fix parts with irregular shapes or requiring combined processing, resulting in difficulties in guaranteeing processing accuracy.

[0021] Example

[0022] like Figures 1-4 As shown, the technical solution in this application aims to effectively address the problem that traditional single-station fixtures can only fix one part at a time for processing. With the continuous expansion of production scale and the increasing demand for product diversification, the processing efficiency of such single-station fixtures is low and cannot meet the progress requirements of mass production. Moreover, their function is relatively limited, making it difficult to accurately position and fix parts with irregular shapes or requiring combined processing, leading to difficulties in guaranteeing processing accuracy. The overall approach is as follows:

[0023] To address the problems existing in the prior art, this utility model provides a dual-station clamping device, including a worktable 21. The worktable 21 serves as the basic support structure of the entire device, providing a stable mounting platform for two sets of movable clamping mechanisms. This ensures that the clamping mechanisms can work stably during processing, preventing instability of the worktable 21 from affecting the machining accuracy of the parts. The worktable 21 is equipped with two sets of movable clamping mechanisms. This dual-station design greatly improves machining efficiency, allowing the two sets of clamping mechanisms to simultaneously process two different parts. Compared to single-station clamping devices, it can complete more machining operations in the same amount of time. The worktable 21 can handle a variety of processing tasks. It can also be used in combination with the two workstations to process some combined parts, meeting diverse processing needs. Two arc-shaped sliding holes 22 and two central holes 23 are provided through the worktable 21. The arc-shaped sliding holes 22 provide a sliding track for the guide screw 12, so that the clamping seat 11 can move along a specific arc-shaped trajectory, thereby realizing flexible adjustment of the angle and position of the clamping mechanism to adapt to parts with different shapes and processing requirements. The central holes 23 provide space for the rotation of the limiting rod 14, ensuring the stability of the limiting rod 14 during rotation, and thus ensuring the rotation accuracy of the clamping seat 11.

[0024] The clamping mechanism includes a clamping seat 11, which is the core load-bearing component of the clamping mechanism. It is used to install and fix other parts, so that the entire clamping action can be carried out in a coordinated manner. A limiting rod 14 is fixedly installed on the clamping seat 11. The limiting rod 14 is rotatably installed in the central hole 23 opened in the worktable 21. Its lower end is provided with a limiting block and fits against the lower end of the worktable 21. This structural design not only restricts the axial movement of the limiting rod 14 and prevents the clamping seat 11 from falling off the worktable 21, but also allows the clamping seat 11 to rotate smoothly about the limiting rod 14 as the axis, realizing the adjustment of the clamping mechanism angle and providing the possibility for machining parts with different angle requirements.

[0025] A guide screw 12 is fixedly installed on the clamping base 11. The guide screw 12 is slidably installed in the arc-shaped sliding hole 22 opened in the worktable 21. A locking nut 13 is threaded through the guide screw 12 and fits against the lower end of the worktable 21. When it is necessary to adjust the position and angle of the clamping mechanism, the locking nut 13 is loosened, and the guide screw 12 can slide in the arc-shaped sliding hole 22, driving the clamping base 11 to rotate. After adjusting to the appropriate position, the locking nut 13 is tightened to fix the clamping mechanism, ensuring that the clamping mechanism will not be displaced during the processing and ensuring the processing accuracy.

[0026] A fixed clamping block 15 is fixedly installed on the clamping base 11, and an L-shaped fixing plate 18 is also fixedly installed. The fixed clamping block 15 is used to provide a fixed clamping reference surface, which cooperates with the movable clamping block 16 to clamp the part. The L-shaped fixing plate 18 provides a mounting base for the adjusting screw 17, ensuring that the adjusting screw 17 can work stably.

[0027] An adjusting screw 17 is threaded through the L-shaped fixed plate 18. A movable clamping block 16 is mounted on the side end of the adjusting screw 17 via a bearing. The movable clamping block 16 is slidably mounted on the clamping seat 11 and is installed correspondingly to the fixed clamping block 15. By rotating the adjusting screw 17, the movable clamping block 16 can smoothly move closer to or further away from the fixed clamping block 15 on the clamping seat 11 using the thread transmission principle. This design allows for convenient and quick adjustment of the clamping distance to meet the clamping requirements of parts of different sizes, thus improving the versatility of the fixture.

[0028] The two clamping mechanisms are symmetrical about the center point of the worktable 21. This symmetrical structural design makes the entire clamping device more balanced in mechanical performance. During the clamping and processing of parts, the force can be evenly distributed, reducing the deformation or processing error of parts caused by uneven force, and further improving the processing accuracy and quality of parts.

[0029] Working principle:

[0030] Part clamping: When machining mechanical parts, the two clamping mechanisms of this device can play a role. The user rotates the adjusting screw 17. Since the adjusting screw 17 is threadedly connected to the L-shaped fixed plate 18 and the adjusting screw 17 is connected to the movable clamping block 16 through a bearing, when the adjusting screw 17 is rotated, the movable clamping block 16 will move on the clamping seat 11. When the movable clamping block 16 moves away from the fixed clamping block 15 and there is enough space, the user places the part to be processed between the two. Then, the adjusting screw 17 is rotated in the opposite direction, and the movable clamping block 16 and the fixed clamping block 15 can clamp the part tightly, providing a stable fixing effect for subsequent processing.

[0031] Dual-station operation: In dual-station mode, if you need to adjust the position of the two clamping mechanisms, the user needs to loosen the locking nut 13 first. At this time, with the center point of the limiting rod 14 as the axis, rotate the clamping seat 11 to rotate the two clamping mechanisms to different positions to meet the needs of processing different parts at the same time and realize dual-station operation.

[0032] Machining of combined parts: When two parts need to be combined for machining, the angle data required for combining the two parts is first transmitted to two sets of clamping mechanisms. The position of the clamping mechanisms is adjusted according to the angle requirements. After the adjustment is completed, the locking nut 13 is tightened to fix the clamping mechanism. In this way, the two sets of clamping mechanisms fix the two parts respectively and maintain a specific angle, which facilitates the combination machining operations such as welding of the two sets of parts. The whole process is convenient to operate and the angle adjustment is flexible.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
