Description

Gear quick clamping device applied to wire EDM equipment Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear quick clamping device applied to wire cutting equipment. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears have been used in transmission for a long time. In the late 19th century, with the emergence of the generating gear cutting method and specialized machine tools and cutting tools using this principle, the smoothness of gear operation became increasingly important as production developed.

[0003] The existing technology, CN202410243772.1, describes a tooling fixture for a wire EDM machine. Its structure is complex and its manufacturing cost is high. Moreover, when clamping some irregularly shaped parts, it may be necessary to clamp and process them multiple times to complete the processing of a product. As shown in Figure 4, the existing product has a protruding shaft on the side of the gear, and a corresponding groove is opened on the shaft. A through hole is opened on the groove surface. Now, it is necessary to cut the shaft into two parts without affecting the groove, and at the same time, it is necessary to ensure that the grooves on both sides are symmetrically arranged after cutting.

[0004] Therefore, it is necessary to design a gear quick clamping device for use on wire cutting equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a gear quick clamping device for use in wire cutting equipment, so as to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gear quick-clamping device for use on a wire cutting machine includes a wire cutting machine, a mounting frame installed in the processing space of the wire cutting machine, a mounting block fixed on the mounting frame, and a gear fixing device installed on the mounting block. The gear fixing device includes a main mounting block installed on the mounting block and used to restrict the gear's axial direction and one end plane, and a planar limiting mechanism disposed on the side of the main mounting block and rotatable. The main mounting block includes a positioning block that cooperates with the mounting block, a circular side positioning block disposed on the side end of the positioning block and perpendicular to the positioning block, and a gear shaft positioning post disposed at the circular position of the circular side positioning block. The planar limiting mechanism includes a fixing block disposed on the side end face of the circular side positioning block, a U-shaped block installed on the side of the fixing block, a rotating block rotatably mounted in the groove of the U-shaped block via a rotating shaft, and a planar limiting block disposed on the rotating block. The planar limiting block has a U-shape.

[0008] Preferably, the mounting block has several sets of mounting holes, and the mounting block also has a trapezoidal groove for avoiding the circular side positioning block.

[0009] Preferably, the planar limiting block and the circular side positioning block are arranged perpendicularly to each other.

[0010] The beneficial effects of this utility model are as follows: This technical solution uses a gear fixing device inside the wire cutting equipment to quickly position the gear. A side positioning block is used to fit and install the gear on its side, limiting its movement. The gear shaft positioning post is used to install the gear, inserting the gear's shaft into the post for axial positioning. The combination of the side positioning block and the gear shaft positioning post allows for rapid gear positioning, ensuring the gear can only rotate around the post. A planar limiting mechanism positions the gear's axial surface, and the groove on the axial surface limits the angle of the entire gear, thus achieving rapid positioning. The structure is simple and enables quick positioning. Attached Figure Description

Detailed Implementation

[0016] Referring to Figures 1 to 3, a gear quick clamping device applied to a wire cutting equipment includes a wire cutting equipment, a mounting frame installed in the processing space of the wire cutting equipment, a mounting block 1 fixed on the mounting frame, and a gear fixing device 2 installed on the mounting block.

[0017] The gear fixing device 2 includes a main mounting block 21 mounted on the mounting block and used to cooperate in limiting the gear axial direction and one end plane, and a planar limiting mechanism 22 disposed on the side of the main mounting block and capable of rotational adjustment;

[0018] The main mounting block 21 includes a positioning block 211 that is installed in conjunction with the mounting fixing block, a circular side positioning block 212 that is disposed on the side end of the positioning block and is perpendicular to the positioning block, and a gear shaft positioning post 213 that is placed at the circular part of the circular side positioning block.

[0019] The side positioning block is used to fit and install the gear on the side, limiting the installation on the side. The gear shaft positioning post is used to install the gear, inserting the gear shaft into the gear shaft positioning post, thereby axially positioning the entire gear. The gear is quickly positioned by the cooperation of the side positioning block and the gear shaft positioning post, so that the gear can only rotate around the gear shaft positioning post as the center.

[0020] The mounting block 1 has several sets of mounting holes 11 for mounting with the gear fixing device. The gear fixing device moves along the surface of the mounting block 1 to the mounting position and is fixed by positioning pins, fixing screws, pins and other fasteners when it matches the corresponding mounting holes.

[0021] The planar limiting mechanism 22 includes a fixing block 221 disposed on the side end face of the circular side positioning block 212, a U-shaped block 222 installed on the side of the fixing block, a rotating block 224 rotatably installed in the groove of the U-shaped block via a rotating shaft 223, and a planar limiting block 225 disposed on the rotating block.

[0022] The planar limiting block has a U-shaped structure, and the gap of the planar limiting block is the same as the groove protruding from the gear to be processed. In order to effectively position the plane of the gear and ensure the accuracy of the angle required for wire cutting of the gear, the planar limiting block and the circular side positioning block 222 are set perpendicular to each other.

[0023] In addition, a trapezoidal groove 12 is provided on the mounting block 1 to avoid the circular side positioning block. The trapezoidal groove, together with the positioning block and the circular side positioning block, can form a sliding structure design similar to a slide rail and a slider, which can slide along the mounting block 1 to adjust the position.

[0024] In this implementation case, referring to Figure 4, the gear 3 that needs to be processed has an irregular structure. It has a protruding shaft on its side with corresponding grooves and through holes on the grooves. The shaft needs to be cut in half to facilitate quick fixing of the two halves during later installation on the equipment using fasteners. However, to achieve this, the shaft angle needs to be ensured. Therefore, this device uses limiting of the grooves on both sides of the shaft for quick positioning, combined with wire cutting. Specifically, the steps include the following, as shown in Figure 3: First, align the shaft center of the gear with the gear... Insert the shaft positioning post 213, and at the same time, make sure that the side of the gear with the meshing teeth is inserted into the circular side positioning block 212 and the circular side positioning block 212 is in contact with the side of the gear. At this time, the gear can rotate around the gear shaft positioning post 213 as the axis. Adjust the angle to be processed, and rotate the plane limiting block 225 with the rotating shaft 223 as the axis. Since the plane limiting block 225 is a U-shaped structure, you only need to manually rotate the gear to make the groove on the gear shaft surface fit with the inner wall of the plane limiting block 225 to complete the angle limitation of the gear. Finally, the gear is wire-cut by a wire cutting device to complete the cutting and separation.

[0025] The advantages of this utility model are that the technical solution uses a gear fixing device inside the wire cutting equipment to quickly position the gear. A side positioning block is used to fit and install the gear on its side, limiting its movement. The gear shaft positioning post is used to install the gear, locking the gear's shaft into the positioning post for axial positioning. The combination of the side positioning block and the gear shaft positioning post allows for rapid gear positioning, ensuring the gear can only rotate around the positioning post. A planar limiting mechanism positions the gear's axial surface, and the groove on the axial surface limits the angle of the entire gear, thus achieving rapid positioning. The structure is simple and enables quick positioning.

[0026] 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.
