Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a novel tooling structure. Background Technology

[0002] In the field of machining, workpiece fixing fixtures are key components for ensuring machining accuracy and efficiency. Currently, traditional fixtures often use bolts for direct tightening, which suffers from low operational efficiency, cumbersome clamping, and an inability to quickly fix multiple workpieces.

[0003] Therefore, those skilled in the art have provided a novel tooling structure to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel tooling structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel tooling structure includes a base plate on which multiple workpieces to be processed are placed on both sides of the top of the base plate, and multiple baffles are fixedly installed on both sides. One side of the workpiece to be processed abuts against the baffle. Multiple sets of clamping components are provided in the middle of the top of the base plate. Each set of clamping components consists of two symmetrically arranged clamping plates, with their opposite sides abutting against the sides of the workpieces to be processed on both sides. The clamping plates are slidably arranged on the base plate, and a trapezoidal expansion plate is slidably arranged between the two symmetrically arranged clamping plates.

[0007] Preferably, a screw through hole is provided in the middle of the trapezoidal expansion plate, and threaded holes are provided on the base plate at the corresponding positions in the middle of the trapezoidal expansion plate.

[0008] Preferably, the two symmetrically arranged clamping plates have an inclined structure on their adjacent sides, and the inclined surfaces on both sides of the trapezoidal expansion plate are respectively in contact with the inclined surfaces of the two clamping plates.

[0009] Preferably, a slider is fixed to the bottom end of the pressing plate, a groove is provided at the top end of the base plate corresponding to the position of the pressing plate, a guide rod is provided inside the groove, the slider is slidably sleeved on one end of the guide rod, and a return spring is sleeved on the other end of the guide rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model can simultaneously fix multiple sets of workpieces to be processed by the cooperation of the baffles on both sides of the base plate and the clamping parts in the middle. Each set of clamping parts consists of symmetrical clamping plates and trapezoidal expansion plates. The trapezoidal expansion plates are driven to move downward by the screw, and the inclined structure is used to simultaneously open the clamping plates on both sides, so as to realize the synchronous clamping of the workpieces on both sides. Compared with the traditional method of clamping single workpieces one by one, it can improve the clamping efficiency.

[0012] Meanwhile, the slider at the bottom of the clamping plate works with the return spring. When disassembling, only the screw needs to be unscrewed, and the return spring will automatically push the clamping plate back. No manual operation is required, which greatly shortens the auxiliary time. The main body of the tooling uses conventional mechanical parts such as the base plate, baffle, and clamping plate. The structure is simple and there are no complex components, resulting in low manufacturing cost. Attached Figure Description

[0018] 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.

[0019] Reference Figure 1-3 A novel tooling structure includes a base plate 1, on which multiple workpieces 2 to be processed are placed on both sides of the top of the base plate 1, and multiple baffles 3 are fixedly installed on both sides. One side of the workpiece 2 to be processed abuts against the baffle 3. Multiple sets of clamping components are provided in the middle of the top of the base plate 1. Each set of clamping components consists of two symmetrically arranged clamping plates 4, whose opposite sides abut against the sides of the workpieces 2 to be processed on both sides. The clamping plates 4 are slidably arranged on the base plate 1, and a trapezoidal expansion plate 5 is slidably arranged between the two symmetrically arranged clamping plates 4.

[0020] The workpiece 2 to be processed is fixed by abutting against the baffle 3 on one side and being pressed by the pressing plate 4 on the other side. The trapezoidal expansion plate 5 is used to spread the two symmetrical pressing plates 4 apart, so that they move away from each other until the pressing plates 4 squeeze and fix the workpiece 2 to be processed.

[0021] A screw through hole 6 is provided in the middle of the trapezoidal expansion plate 5, and threaded holes 7 are provided on the bottom plate 1 at the corresponding middle position of the trapezoidal expansion plate 5.

[0022] A screw is installed through the screw through hole 6 in the middle of the trapezoidal expansion plate 5. The bottom end of the screw is screwed into the threaded hole 7 of the base plate. When the screw is turned, the head of the screw drives the trapezoidal expansion plate 5 to move downward, thereby gradually opening the two clamping plates 4 outward, and the distance gradually increases until the baffle 3 firmly holds the workpiece to be processed.

[0023] The two symmetrically arranged clamping plates 4 have an inclined structure on one side of each other, and the inclined surfaces on both sides of the trapezoidal expansion plate 5 are respectively attached to the inclined surfaces of the two clamping plates 4;

[0024] The inclined surfaces on both sides of the trapezoidal expansion plate 5 contact the inclined surfaces of the pressing plate 4. Thus, when the trapezoidal expansion plate 5 moves vertically downward due to the action of the screw, it will apply a horizontal component force to the pressing plate 4 through the inclined surfaces, thereby causing the pressing plate 4 to slide horizontally.

[0025] A slider 41 is fixedly connected to the bottom end of the clamping plate 4. A groove 42 is provided at the top of the bottom plate 1 corresponding to the position of the clamping plate 4. A guide rod 43 is provided inside the groove 42. The slider 41 is slidably sleeved on one end of the guide rod 43, and a return spring 44 is sleeved on the other end of the guide rod 43.

[0026] The clamping plate 4 is able to slide horizontally on the surface of the base plate 1 through the setting of the slider 41 and the slide groove 42. The guide rod 43 can limit the movement direction of the clamping plate 4 and prevent it from falling off the base plate. The return spring 44 can make the slider 41 initially located at one end of the slide groove 42 through the elastic force. When the trapezoidal expansion plate 5 causes the clamping plate 4 to slide, it will compress the return spring 44. Subsequently, when it comes into contact with the restriction of the trapezoidal expansion plate 5, the return spring 44 will rebound and reset through the rebound force, thereby disassembling the workpiece to be processed.

[0027] Working principle:

[0028] When fixing the workpiece 2 to be processed, place the workpiece 2 on the base plate 1 and make one side of it abut against the baffle 3. The screw rod passes through the screw rod through the through hole 6 in the middle of the trapezoidal expansion plate 5 and the bottom end of the screw rod is screwed into the corresponding threaded hole 7. Continue to screw the screw rod downward, so that the head of the screw rod drives the trapezoidal expansion plate 5 to move vertically downward. This causes the two inclined surfaces of the trapezoidal expansion plate 5 to apply a horizontal component force to the two clamping plates 4 on both sides, so that the two clamping plates 4 move away from each other until the clamping plates 4 and the corresponding baffle 3 clamp the workpiece 2 to be processed. During the movement of the clamping plates 4, the slider 41 will compress the return spring 44. After the workpiece is processed, the screw rod is unscrewed, and the return spring 44 will rebound to reset the clamping plates 4, thereby releasing the fixing effect on the workpiece.

[0029] 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.
