Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a machining fixture for electroforming parts. Background Technology

[0002] In the field of machining, clamping fixtures are used to fix workpieces. Clamping fixtures enable the workpieces to be in the correct position during the machining process so that they can be installed or inspected. In a broad sense, any device used to quickly, conveniently and safely install workpieces in any step of the process can be called a clamping fixture.

[0003] Utility model patent CN217619193U discloses a machining fixture for wind turbine castings, including a machining table with a first bidirectional lead screw slide inside. This machining fixture for wind turbine castings features a first bidirectional lead screw slide and a second bidirectional lead screw slide, which can respectively drive two first support plates and two second support plates to move and adjust relative to each other. The four support plates can adapt to brake disc castings of different diameters according to the adjusted diameter, thus ensuring stable placement on the support plate surfaces. The threaded rods connected to the first support plates and second fixed plates can be rotated downwards, causing their lower ends to press against the brake disc casting surface for clamping and fixing. The four pressure plates greatly improve the subsequent machining stability of the casting. Ball bearings on the support plate surfaces ensure smooth mutual movement between the support plates and the casting.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: when adjusting the position of the first support plate, the first bidirectional lead screw slide and the second bidirectional lead screw slide need to be started simultaneously, which will make the equipment control system complicated. In addition, the surface of the first support plate is equipped with balls. Although the design of the balls can meet the rotation requirements of the workpiece, after the workpiece is clamped on the surface of the first support plate, the presence of the balls will make the equipment prone to movement, which will lead to errors during workpiece processing.

[0016] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0017] Please see Figure 1-5 A machining and clamping fixture for electroforming parts includes an adjustment mechanism 1, a rotary drive mechanism 2 on one side of the adjustment mechanism 1, and four clamping mechanisms 3 arranged in a ring array above the adjustment mechanism 1. The adjustment mechanism 1 includes a bracket 101, a circular slide rail 102 fixed to the top of the bracket 101, a slider 103 slidably connected to the surface of the circular slide rail 102, an mounting cylinder 104 fixed to the top of the slider 103, a first motor 105 fixed at the bottom center of the mounting cylinder 104, an opening on the top of the bracket 101 for inserting the first motor 105, an output shaft of the first motor 105 passing through the mounting cylinder 104 and a drive shaft 106 fixed thereto, the top of the drive shaft 106 rotatably connected to the top of the inner wall of the mounting cylinder 104, a drive disc 107 fixed to the surface of the drive shaft 106, four arc-shaped grooves 108 formed on the surface of the drive disc 107, four straight sliding grooves 109 formed on the top of the mounting cylinder 104, a sliding plate 110 slidably connected to the surface of the straight sliding grooves 109, a connecting shaft 111 fixed to the bottom of the sliding plate 110, a rotating wheel 112 rotatably connected to the surface of the connecting shaft 111, the rotating wheel 112 slidably connected to the surface of the arc-shaped grooves 108, and a support plate 113 fixed to the top of the sliding plate 110.

[0018] Through the above technical solution, the adjustment mechanism 1 serves as the basic structure of the entire clamping fixture. Through the sliding connection between the circular slide rail 102 on the top of the bracket 101 and the slider 103, the mounting cylinder 104 can rotate on the circular slide rail 102. Under the drive of the first motor 105, the drive shaft 106 drives the drive disk 107 to rotate, and the rotating wheel 112 slides in the arc groove 108, thereby driving the sliding plate 110 to move in the straight slide groove 109, thus realizing the synchronous movement of the support plate 113 to adapt to electroformed parts of different shapes and sizes. The four ring array-distributed clamping mechanisms 3 cooperate with the support plate 113 to achieve stable clamping of the electroformed parts. The design of this adjustment mechanism 1 realizes the synchronous movement of multiple support plates 113 through the drive of the first motor 105, which improves the versatility and adaptability of the clamping fixture. The entire adjustment mechanism 1 has a compact structure, is easy to operate, and reduces the complexity and maintenance cost of the equipment.

[0019] The rotary drive mechanism 2 includes an extension plate 201, which is fixed to one side of the bracket 101. A second motor 202 is fixed to the bottom of the extension plate 201. The output shaft of the second motor 202 passes through the extension plate 201 and is fixed to a connecting rod. A gear 203 is fixed to the surface of the connecting rod. A gear ring 204 meshes with the surface of the gear 203. The gear ring 204 is fixed to the side surface of the mounting cylinder 104.

[0020] With the above technical solution, when the second motor 202 is working, its output shaft drives the connecting rod and gear 203 to rotate. The meshing relationship between gear 203 and gear ring 204 causes the mounting cylinder 104 to rotate around the central axis of the bracket 101 on the circular slide rail 102, thereby driving the electrocasting parts on the entire clamping fixture to rotate to meet the requirements of different processing angles.

[0021] The clamping mechanism 3 includes an extension frame 301, which is fixed to the side surface of the mounting cylinder 104. A first lead screw 302 is threaded through the surface of the extension frame 301. One end of the first lead screw 302 is rotatably connected to a mounting block 303. A second lead screw 304 is threaded through the surface of the mounting block 303. A clamping block 305 is fixed to the bottom of the second lead screw 304.

[0022] With the above technical solution, when it is necessary to clamp the electroformed part, by rotating the first lead screw 302 and the second lead screw 304, the mounting block 303 and the clamping block 305 can be moved on the extension frame 301, thereby adjusting the position of the clamping block 305 and realizing the clamping or loosening of the electroformed part. The four clamping mechanisms 3 distributed in a ring array work together to ensure the stable fixation of the electroformed part during the processing.

[0023] A guide rod 306 slides through the surface of the extension frame 301, and one end of the guide rod 306 is fixedly connected to the surface of the mounting block 303.

[0024] Through the above technical solution, when the first lead screw 302 is rotated to move the mounting block 303, the guide rod 306 provides guidance and support for the movement of the mounting block 303 under the sliding penetration action of the extension frame 301, ensuring that the mounting block 303 moves smoothly along the predetermined trajectory, thereby ensuring the movement accuracy and stability of the clamping block 305 and improving the working reliability of the clamping mechanism 3.

[0025] Two wheel frames 114 are fixed at the bottom of the support plate 113. Rollers 115 are rotatably connected to the surface of the wheel frames 114. The surface of the rollers 115 is slidably connected to the top of the mounting cylinder 104.

[0026] With the above technical solution, when the clamping fixture is adjusting the position of the support plate 113, the roller 115 slides on the top of the mounting cylinder 104, which reduces the friction between the support plate 113 and the mounting cylinder 104, making the movement and rotation of the support plate 113 smoother and improving the working efficiency and flexibility of the adjustment mechanism 1.

[0027] Multiple universal balls 116 are fixed at the bottom of the drive disk 107, and the surface of the universal balls 116 is slidably connected to the bottom of the inner wall of the mounting cylinder 104.

[0028] Through the above technical solution, when the drive disc 107 drives the support plate 113 to move and rotate, the universal ball 116 slides on the bottom of the inner wall of the mounting cylinder 104, providing multi-directional support and drag reduction for the drive disc 107.

[0029] Both the first motor 105 and the second motor 202 are worm gear reducers.

[0030] Through the above technical solution, the worm gear reducer motor has self-locking property. When the motor stops running, it can prevent the load from driving the motor in reverse through the meshing of the worm gear, thereby ensuring the stability of the clamping fixture in the non-working state and preventing the position of the support plate 113 and the mounting cylinder 104 from shifting.

[0031] Working Principle: During operation, the first motor 105 in the adjusting mechanism 1 drives the drive shaft 106 and drive disk 107 to rotate according to the size of the electroformed part. This, in turn, adjusts the position of the support plate 113 through the cooperation of the sliding plate 110, linear groove 109, and arc groove 108. Then, the clamping mechanism 3 fixes the electroformed part onto the support plate 113. Next, the rotary drive mechanism 2 rotates the clamping fixture to position the electroformed part in a suitable machining position before machining. Throughout the process, the rollers 115 and universal balls 116 provide drag reduction and support at the bottom of the support plate 113 and drive disk 107, respectively, ensuring the stable operation of the clamping fixture. This electroformed part machining clamping fixture solves the shortcomings of traditional clamping equipment in terms of adjustment complexity, clamping stability, and rotary machining capability. Through the combination of the adjusting mechanism 1, the rotary drive mechanism 2, and the clamping mechanism 3, it achieves efficient and stable clamping and multi-angle machining of electroformed parts, improving machining accuracy and efficiency while reducing equipment complexity.
