Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a multi-station rectangular coaxial rotatable wire cutting fixture. Background Technology

[0002] Wire EDM fixtures are devices used to hold the workpiece in place during wire EDM machining. Their main function is to ensure the workpiece is in the correct machining position for precise cutting. Existing wire EDM fixtures require manual tightening, resulting in long clamping times and reduced production efficiency.

[0003] To address the aforementioned issues, patent document CNU discloses a wire EDM fixture. This fixture includes a fixture fixing shell, on which a first and second air inlet / outlet pipe are mounted. A pneumatic clamping mechanism is installed inside the fixture fixing shell, and a positioning mechanism is provided between the fixture fixing shell and the workpiece. The pneumatic clamping mechanism includes a spring fixing base, with guide slides on one side surface. Each guide slide has a threaded hole, with both ends of the threaded hole connected. A first fixing bolt is installed inside the threaded hole. One end of each guide slide passes through the spring fixing base. Multiple spring mounting holes are provided on the spring fixing base, and return springs are installed in each of these holes. A movable seat is slidably connected to the guide slides. A movable boss is fixedly connected to the top surface of the movable seat. A sleeve is provided outside the movable boss, and a second fixing bolt is installed on the sleeve. A first step and a second step are provided at the top of the movable boss. The positioning mechanism includes two positioning sliders and two positioning bosses. Positioning grooves are provided on the bottom surfaces of the two positioning sliders.

[0004] It can be seen that the above-mentioned fixture achieves automatic clamping of workpieces by setting up a pneumatic clamping mechanism, shortening manual clamping time and improving production efficiency. However, the above-mentioned fixture is a fixed fixture, which cannot flexibly adjust the clamping angle of the workpiece during processing. When processing workpieces with complex shapes, it is necessary to frequently change the fixture or re-clamp the workpiece, which not only increases the labor intensity of workers but also reduces processing efficiency. In addition, the above-mentioned fixture has few clamping stations, making it impossible to process multiple workpieces simultaneously, resulting in low processing efficiency. Utility Model Content

[0005] This invention provides a multi-station rectangular coaxial rotatable wire EDM fixture to solve the technical problem that existing wire EDM fixtures cannot adjust the clamping angle of the workpiece during processing, resulting in high labor intensity for workers and low workpiece processing efficiency.

[0006] To solve the above problems, the multi-station rectangular coaxial rotatable wire EDM fixture provided by this utility model adopts the following technical solution:

[0007] A multi-station rectangular coaxial rotatable wire EDM fixture, comprising:

[0008] The base has a shaft hole at its center, and a horizontally extending rotating shaft is installed in the shaft hole;

[0009] A rotating disk is mounted on the rotating shaft, and the rotating disk has a clamping station for mounting clamping parts, the extending direction of the clamping station being parallel to the extending direction of the rotating shaft.

[0010] A clamping member is installed in the clamping station and has clamping holes for clamping workpieces.

[0011] A limiting member is horizontally installed on the top of the base and extends above the rotating disk. The limiting member and the base have corresponding mounting holes. A connector for connecting the limiting member and the base is detachably installed in the mounting holes. The limiting member is used to restrict the rotation of the rotating disk.

[0012] The beneficial effects of the multi-station rectangular coaxial rotatable wire EDM fixture provided by this utility model are:

[0013] 1. By installing a rotating shaft at the center of the base, a rotating disk is installed on the rotating shaft, and a clamping station for installing clamping parts is set on the rotating disk. The rotation of the rotating shaft drives the rotating disk to rotate, thereby driving the clamping parts installed on the rotating disk to rotate, and thus driving the workpiece installed in the clamping parts to rotate, so as to realize the flexible adjustment of the workpiece clamping angle.

[0014] 2. By installing a limiting component extending above the rotating disk on the top of the base, the rotation angle of the rotating disk is limited when the workpiece is wire-cut, thereby preventing the workpiece from rotating during processing and affecting the workpiece processing quality.

[0015] Through the above-mentioned design, this utility model effectively solves the technical problem in the prior art that the wire cutting fixture cannot adjust the clamping angle of the workpiece during the processing, resulting in high labor intensity for workers and low workpiece processing efficiency.

[0016] Furthermore, the outer surface of the clamping member has two opposing planes, and the clamping station matches the shape of the clamping member.

[0017] Furthermore, the number of clamping stations is multiple.

[0018] Furthermore, the multiple clamping stations are arranged in a matrix on the rotating disk.

[0019] Furthermore, the clamping element is a nut, and the end of the workpiece is screwed into the nut.

[0020] Furthermore, a bearing is installed in the shaft hole, and the rotating shaft is installed inside the bearing.

[0021] Furthermore, the rotating disk has a rectangular structure.

[0022] Furthermore, the connecting component is a pin.

[0023] Furthermore, the end of the rotating shaft connected to the rotating disk has a stepped section, the radial dimension of which is larger than the radial dimension of the shaft hole. A limit block is provided at the end of the rotating shaft away from the rotating disk, and the limit block is located on the side of the base away from the rotating disk to limit the horizontal movement of the rotating shaft.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] It should be noted that the main concept of the multi-station rectangular coaxial rotatable wire EDM fixture provided by this utility model is as follows: by installing a rotating shaft on the base, a rotating disk on the rotating shaft, and a clamping component on the rotating disk, the workpiece is clamped by the clamping component. The rotation of the rotating shaft drives the rotating disk to rotate, which in turn drives the clamping component installed on the rotating disk to rotate, thereby driving the workpiece installed in the clamping component to rotate. This allows for flexible adjustment of the workpiece clamping angle. By installing a limiting component extending above the rotating disk on the top of the base, the rotation of the workpiece during the processing is restricted by the limiting component, which can effectively ensure the processing quality.

[0032] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0033] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0035] like Figures 1 to 3 As shown, the multi-station rectangular coaxial rotatable wire cutting fixture includes a base 1, a shaft hole is opened at the center of the base 1, a horizontally extending rotating shaft 2 is installed in the shaft hole, a rotating disk 3 is installed on the rotating shaft 2, a clamping member 4 is installed on the rotating disk 3, and a limiting member 5 that extends horizontally to the top of the base 1 above the rotating disk 3 is installed.

[0036] The following describes the installation of the rotating disk 3 and the clamping component 4 on the rotating disk 3. The rotating disk 3 is mounted on the rotating shaft 2 and has a rectangular structure. The rotating disk 3 has a clamping station for installing the clamping component 4. The extension direction of the clamping station is parallel to the extension direction of the rotating shaft 2, and the clamping component 4 is installed in the clamping station.

[0037] There are sixteen clamping stations, which are arranged in a 4×4 matrix on the rotating disk 3. Each clamping station is equipped with a clamping component 4. The clamping component 4 is a nut with internal threads for selecting the end of the workpiece. The outer surface of the clamping component 4 has two opposing planes 7. The shape of the clamping station matches that of the clamping component 4.

[0038] Next, we will describe the installation of the limiting member 5 on the base 1. The left end of the limiting member 5 has an installation hole, and the top surface of the base 1 has an installation hole corresponding to the position and size of the installation hole on the limiting member 5. The connecting member 6 passes through the installation hole on the limiting member 5 and extends into the installation hole on the base 1, thereby realizing the installation of the limiting member 5 on the base 1.

[0040] In addition, the base 1 has an L-shaped structure, including a vertical section, the bottom of which is connected to a horizontal section extending to the left. The limiting member 5 is installed at the top of the vertical section, and the shaft hole is opened at the center of the vertical section. A bearing 8 is installed in the shaft hole, and the left end of the rotating shaft 2 is installed in the bearing 8. The right end of the rotating shaft 2 has a stepped section with progressively increasing radial dimensions. The radial dimensions of the stepped section are all greater than the radial dimensions of the shaft hole. The left end of the rotating shaft 2 is connected to a limiting block 9 by bolts 10. The limiting block 9 is located on the side of the base 1 away from the rotating disk 3 to restrict the horizontal movement of the rotating shaft 2.

[0041] The working principle of the multi-station rectangular coaxial rotatable wire cutting fixture provided by this utility model is as follows:

[0042] Taking the processing of the tubular shaping sleeve 11 as an example, firstly, the base 1 is installed on the wire cutting machine, the limiting member 5 is placed on the top surface of the base 1, and the connector 6 is inserted into the mounting hole to fix the limiting member 5 on the base 1. Then, one end of the tubular shaping sleeve 11 is screwed into the clamping member 4, the clamping member 4 is installed in the clamping position, and then the wire cutting machine is started to perform wire cutting processing on the top surface (i.e., 0° surface) and bottom surface (i.e., 180° surface) of the tubular shaping sleeve 11.

[0043] After processing is completed, turn off the wire EDM machine, remove the connector 6 and the limiting member 5, then rotate the rotating disk 3 by 90°. After rotation, reinstall the limiting member 5 on the base 1 and start the wire EDM machine again to perform wire EDM processing on the other two sides (i.e., the 90° surface mixed with the 360° surface) of the tubular shaping sleeve 11.

[0044] Embodiment 2 of the multi-station rectangular coaxial rotatable wire cutting fixture provided by this utility model:

[0045] Its main difference from Example 1 is:
