Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for one-time processing of products with interchangeable molds. Background Technology

[0002] A fixture is a process device used in mechanical manufacturing to fix a workpiece in the correct position for processing or inspection. Fixtures can accurately position the workpiece in a specific location and maintain its position, ensuring the stability and accuracy of the workpiece during processing.

[0003] Existing fixtures require two processes to complete the machining of both sides of a workpiece in actual use. This method is not only inefficient, but also prone to problems such as inaccurate datum positioning and inability to guarantee behavioral tolerances, resulting in inaccurate machining results. Therefore, it is necessary to provide a fixture that can process products in one step with interchangeable molds, so that after machining the front side of the workpiece, it can be flipped over to machine the reverse side, which can not only meet the drawing requirements, but also improve machining efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for one-time processing of interchangeable mold products, in order to solve the problem mentioned in the background art, that existing fixtures require two processes to complete the processing of both sides of the workpiece in actual use. This method is not only inefficient, but also has the problem of inaccurate datum and inability to guarantee behavioral tolerance, resulting in inaccurate processing results.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fixture for one-time processing of interchangeable molded products, comprising:

[0007] The processing assembly includes a base plate, a mounting hole, a workpiece, a limiting plate, and a limiting hole. The mounting hole is located inside the base plate, the workpiece is held inside the mounting hole, the limiting plate is attached to the upper surface of the base plate, and the limiting hole is located inside the limiting plate. The cross-section of the limiting hole is trapezoidal, and the trapezoid is wider at the top and narrower at the bottom. The mounting hole, the workpiece, and the limiting hole are coaxial.

[0008] Furthermore, connecting holes are provided inside the two sides of the base plate, and limit blocks are fixed on the upper surface of the two sides of the base plate, with the limit plate being locked between the limit blocks.

[0009] Furthermore, it also includes limiting components located at both ends of the processing component;

[0010] The limiting assembly includes a support column, a fixing hole, a support frame, a limiting rod, and a movable plate. The support column is fixed inside the base plate and is connected through the inside of the limiting plate. The fixing hole is opened at the top of the support column and the limiting plate. The support frame is fixed on the outer surface of both ends of the base plate. The limiting rod is located inside the fixing hole, and the movable plate is fixed on the outer surface of the limiting rod.

[0011] Furthermore, a spring is fixed between the movable plate and the support frame, and a connecting column is fixed on the outer surface of the movable plate. The connecting column passes through and connects to the interior of the support frame, and a round hole is opened inside the connecting column.

[0012] Furthermore, a fixing plate is fixed to the outer surface of the support frame, and a movable rod is connected through the inside of the fixing plate. The movable rod is located inside the circular hole at the outer end, and a guide plate is fixed to the outer surface of the movable rod.

[0013] Furthermore, the guide plate has a connecting groove inside, and a fixing post is fixed on the outer surface of the fixing plate. The fixing post is connected through the inside of the guide plate, and a rotating block is rotatably connected to the outer surface of the fixing post. Magnets are embedded in the rotating block and inside the guide plate.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through its processing components, allows for the connection of a base plate and a rotating base plate assembly via connecting holes when processing a workpiece. The workpiece is then placed inside the mounting hole, securing it within the base plate. Under the action of limiting blocks, a limiting plate is secured between the limiting blocks. Conversely, the workpiece is clamped between the base plate and the limiting plate by the limiting holes. With the mounting hole and limiting holes in place, once one side of the workpiece is processed, a flipping force is applied to the base plate to process the other side. This design allows for direct flipping of the workpiece after processing the front side, ensuring not only compliance with drawing requirements but also improved processing efficiency.

[0016] II. Based on the first beneficial effect, when the limiting component is used in conjunction with the limiting component, and the limiting plate needs to be fixed to the top of the base plate, firstly, a rotational force is applied to the rotating block to make the rotating block conform to the shape of the connecting groove. Then, a pulling force is applied to the guide plate to drive the movable rod out of the connecting column. After the connecting column is no longer restricted, under the action of the spring force, the connecting column drives the movable plate to change position, so that the limiting rod is inserted into the fixing hole. That is, the limiting rod is inserted into the support column and the limiting plate. Then, a pushing force is applied to the guide plate to make the movable rod insert into the outer round hole. Finally, a rotational force is applied to the rotating block to connect the two sets of magnets together. This solution can quickly and easily adjust the position of the limiting rod, thereby completing the locking and releasing of the limiting plate. Attached Figure Description

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1 and Figure 2 As shown, this embodiment is a fixture for one-time processing of interchangeable mold products, including:

[0029] The processing assembly includes a base plate 11, a mounting hole 14, a workpiece 15, a limiting plate 16, and a limiting hole 17. The mounting hole 14 is opened inside the base plate 11, the workpiece 15 is inserted into the mounting hole 14, the limiting plate 16 is attached to the upper surface of the base plate 11, and the limiting hole 17 is opened inside the limiting plate 16. The cross-section of the limiting hole 17 is trapezoidal, and the trapezoid is wider at the top and narrower at the bottom. The mounting hole 14, the workpiece 15, and the limiting hole 17 are coaxial.

[0030] The base plate 11 serves as the basic component of the entire fixture, providing an installation base and support platform for the workpiece 15 and the limiting plate 16. The mounting holes 14 are used to house the workpiece 15 inside the base plate 11, and multiple sets of mounting holes 14 are provided, allowing multiple sets of workpieces 15 to be processed at once. The workpiece 15 is the object being processed. The limiting plate 16 is used to confine the workpiece 15 inside the mounting holes 14, and the limiting holes 17 are used to facilitate the processing of the workpiece 15 inside the base plate 11 by other parts.

[0031] Connecting holes 12 are provided inside both sides of the base plate 11, and limiting blocks 13 are fixed on the upper surface of both sides of the base plate 11, with limiting plates 16 being inserted between the limiting blocks 13.

[0032] The connecting hole 12 is used to connect with the driving component of the rotating base plate 11, and the limiting block 13 is used to quickly place the limiting plate 16 in the desired position.

[0033] Working principle: When workpiece 15 needs to be processed, firstly, the assembly of base plate 11 and rotating base plate 11 is connected by connecting hole 12. Workpiece 15 is placed inside mounting hole 14, so that workpiece 15 is stuck inside base plate 11. Under the action of limiting block 13, limiting plate 16 is stuck between limiting blocks 13. Under the restriction of limiting hole 17, workpiece 15 can be clamped between base plate 11 and limiting plate 16. With the setting of mounting hole 14 and limiting hole 17, after one side of workpiece 15 is processed, a flipping force is applied to base plate 11 to process the other side of workpiece 15.

[0034] This step allows the workpiece 15 to be directly flipped over for processing the reverse side after the front side is machined, which not only ensures the drawing requirements but also improves processing efficiency.

[0035] Please see Figure 1 , Figure 3 and Figure 4 As shown, this embodiment, based on the above embodiment, further includes a limiting component, which is located at both ends of the processing component;

[0036] The limiting assembly includes a support column 21, a fixing hole 22, a support frame 23, a limiting rod 24, and a movable plate 25. The support column 21 is fixed inside the base plate 11 and is also connected through the inside of the limiting plate 16. The fixing hole 22 is opened at the top of the support column 21 and the limiting plate 16. The support frame 23 is fixed on the outer surfaces of both ends of the base plate 11. The limiting rod 24 is located inside the fixing hole 22. The movable plate 25 is fixed on the outer surface of the limiting rod 24.

[0037] The support column 21 is used to connect with the limiting rod 24, thereby limiting the limiting plate 16 in the required position. The fixing hole 22 provides a space for the limiting rod 24 to be received. The movable plate 25 is used to change the position of the limiting rod 24.

[0038] A spring 26 is fixed between the movable plate 25 and the support frame 23. A connecting post 27 is fixed on the outer surface of the movable plate 25. The connecting post 27 passes through and connects to the inside of the support frame 23. A round hole 28 is opened inside the connecting post 27.

[0039] Spring 26 provides elastic restoring force for movable plate 25, connecting post 27 facilitates changing the position of movable plate 25, and round hole 28 is used to connect with movable rod 291, thereby fixing movable plate 25 in different positions;

[0040] A fixing plate 29 is fixed to the outer surface of the support frame 23. A movable rod 291 is connected through the inside of the fixing plate 29. The movable rod 291 is located inside the outer end round hole 28. A guide plate 292 is fixed to the outer surface of the movable rod 291.

[0041] The fixed plate 29 is used for the horizontal movement of the movable rod 291 inside it. The movable rod 291 is used to restrict the connecting column 27 to the desired position, and the guide plate 292 facilitates changing the position of the movable rod 291.

[0042] The guide plate 292 has a connecting groove 293 inside, and a fixing post 294 is fixed on the outer surface of the fixing plate 29. The fixing post 294 passes through and is connected to the inside of the guide plate 292. A rotating block 295 is rotatably connected to the outer surface of the fixing post 294. Magnets 296 are embedded in the rotating block 295 and inside the guide plate 292.

[0043] The connecting groove 293 is used for the rotating block 295 to pass through the interior of the guide plate 292. The fixing post 294 is used to support and install the fixing plate 29, and then support and install the rotating block 295. By applying a rotational force to the rotating block 295, the guide plate 292 is restricted to the desired position. The magnet 296 is used to restrict the rotating block 295 to the desired position.

[0044] Working principle: When the limiting plate 16 needs to be fixed on the top of the base plate 11, firstly, a rotational force is applied to the rotating block 295 so that the rotating block 295 is consistent with the shape of the connecting groove 293. Then, a pulling force is applied to the guide plate 292, causing the movable rod 291 to disengage from the inside of the connecting column 27. After the connecting column 27 is no longer restricted, under the elastic force of the spring 26, the connecting column 27 drives the movable plate 25 to change position, so that the limiting rod 24 is inserted into the fixed hole 22, that is, the limiting rod 24 is inserted into the support column 21 and the limiting plate 16. Then, a pushing force is applied to the guide plate 292 so that the movable rod 291 is inserted into the outer round hole 28. Finally, a rotational force is applied to the rotating block 295 so that the two sets of magnets 296 are connected together.

[0045] This step allows for a quick and easy adjustment of the position of the limit rod 24, thereby completing the locking and releasing of the limit plate 16.
