Description

Technical Field

[0001] This utility model relates to the field of wire EDM machine technology, specifically a movable parts clamping platform for wire EDM. Background Technology

[0002] Aero-engine components require wire EDM (Electrical Discharge Machining) for cutting during processing, assembly, testing, and after a period of service. A wire EDM machine mainly consists of three parts: a machine tool, a CNC system, and a high-frequency power supply. To improve cutting stability, a movable clamping platform is typically used to hold the parts during wire EDM.

[0003] Regarding the aforementioned technologies, the applicant believes that when a movable part clamping platform for wire EDM is in operation, the part to be processed is first placed on the work platform, and then the work table can be moved by the operation of the lead screw motor, which can easily move the part to the cutting head, thereby facilitating the cutting of the part. However, the part will move during the movement of the work table, which will cause the processing position of the part to shift, thereby affecting the processing quality of the part. Utility Model Content

[0004] The purpose of this invention is to provide a movable part clamping platform for wire EDM, in order to solve the problem mentioned in the background art that the part moves during the movement of the worktable, thereby causing the part's processing position to shift and affecting the part's processing quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a movable part clamping platform for wire cutting, comprising a fixed base, a moving mechanism, and a clamping mechanism. The moving mechanism is disposed inside the fixed base, and the clamping mechanism is disposed at the top of the fixed base. The clamping mechanism includes a support frame disposed at the top of the moving mechanism. The support frame is U-shaped, and a threaded rod is threaded through the top of the support frame longitudinally relative to the moving mechanism. The threaded rod is disposed at the middle position of the top of the support frame. The threaded rod moves longitudinally inside the support frame. A clamping plate is disposed at the bottom of the threaded rod. The clamping plate is a rectangular block and is disposed inside the support frame. The threaded rod drives the clamping plate to move up and down inside the support frame. A handle is disposed at the top of the threaded rod, and the handle drives the threaded rod to rotate.

[0006] By adopting the above technical solution, the parts to be cut are passed through the inside of the two support frames. Then, by rotating the handle, the threaded rod can be rotated, which can push the clamping plate downward. This makes it easy to fix the parts inside the support frames and minimizes the displacement of the parts when the support blocks move.

[0008] By adopting the above technical solution, the operation of the drive motor can drive the lead screw to rotate, which can drive the movable block on the lead screw to move. Through the transmission of the movable rod and the support block, the fixed parts on the support block can be moved, and the parts can be moved to the cutting head of the wire cutting machine.

[0009] Preferably, the support frame is provided in two sets, which are symmetrically distributed about the movable block.

[0010] By adopting the above technical solution, parts of different lengths can be easily placed inside the support frame, thereby improving the applicability of the device.

[0011] Preferably, a limiting plate is provided in the middle part of the top of the support frame, the handle passes through the interior of the limiting plate, and limiting holes are evenly opened at the top of the limiting plate.

[0012] By adopting the above technical solution, it is convenient to limit the grip position.

[0013] Preferably, the bottom end of the clamping plate is provided with a protective pad, which is made of rubber.

[0014] By adopting the above technical solution, it is possible to easily protect the fixed parts and minimize the damage to the parts caused by the clamp.

[0015] Preferably, a connecting rod is provided through the inside of the grip, a limiting spring is sleeved on the outside of the connecting rod, and a locking block is provided at the bottom end of the connecting rod, which matches the limiting hole.

[0016] By adopting the above technical solution, the handle can be easily limited, minimizing the possibility of the handle rotating during device operation.

[0017] Preferably, the limiting holes are provided in eight sets, and the limiting holes are evenly distributed in a circular shape at the top of the limiting plate.

[0018] By adopting the above technical solution, it is convenient to limit the grip at different positions.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By setting up a moving mechanism, clamping mechanism, support frame, clamping plate, threaded rod, handle, limit spring and connecting rod, the part to be cut passes through the inside of the two support frames.

[0021] 2. By setting a limit plate, grip, limit hole, locking block and limit spring, when the grip is rotated to the appropriate position, the elasticity of the limit spring can push the locking block into the limit hole inside the limit plate, which can conveniently limit the grip and minimize the rotation of the grip when the device is working, thus effectively improving the stability of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1 to 4This embodiment provides a technical solution: a movable part clamping platform for wire cutting, including a fixed base 2, a moving mechanism 1, and a clamping mechanism 3. The moving mechanism 1 is disposed inside the fixed base 2, and the clamping mechanism 3 is disposed at the top of the fixed base 2. The clamping mechanism 3 includes a support frame 301 fixedly connected to the top of the moving mechanism 1. The support frame 301 is U-shaped and can provide load-bearing capacity. A threaded rod 303 is threaded through the top of the support frame 301. The threaded rod 303 is disposed at the middle position of the top of the support frame 301 and is used for longitudinal movement within the support frame 301. A clamping plate 302 is rotatably connected to the bottom end of the threaded rod 303. The clamping plate 302 is set inside the support frame 301 and is used by the threaded rod 303 to drive the clamping plate 302 to move up and down inside the support frame 301. A protective pad made of rubber is fixedly connected to the bottom end of the clamping plate 302 to protect the fixed parts and minimize damage to the parts caused by the clamping plate 302. A handle 305 is fixedly connected to the top end of the threaded rod 303 to drive the threaded rod 303 to rotate. By rotating the handle 305, the threaded rod 303 can be rotated, which can push the clamping plate 302 to move downward, so as to easily fix the parts to the support block 101 and minimize the displacement of the parts when the support block 101 moves.

[0030] Example 2

[0031] A drive motor 104 is fixedly connected to one end of the fixed base 2. A lead screw 103 is fixedly connected to the output end of the drive motor 104. A movable block 105 is engaged with the outside of the lead screw 103. A movable rod 102 is fixedly connected to the top of the movable block 105. Support blocks 101 are fixedly connected to both sides of the top of the movable rod 102. A support frame 301 is fixedly connected to the middle part of the top of the support block 101. The operation of the drive motor 104 can drive the lead screw 103 to rotate, which can drive the movable block 105 on the lead screw 103 to move. Through the transmission of the movable rod 102 and the support block 101, the parts fixed on the support block 101 can be moved to the cutting head of the wire cutting machine, so as to facilitate the cutting of the parts. Two sets of support frames 301 are provided. The support frames 301 are symmetrically distributed about the movable blocks 105, which can facilitate the placement of parts of different lengths into the support frame 301, thereby improving the applicability of the device.

[0032] Example 3

[0033] A limiting plate 304 is fixedly connected to the middle part of the top of the support frame 301. The limiting plate 304 can provide load-bearing capacity. The handle 305 passes through the interior of the limiting plate 304. Limiting holes 306 are evenly opened at the top of the limiting plate 304. A connecting rod 309 is installed through the interior of the handle 305. A limiting spring 308 is sleeved on the outside of the connecting rod 309. A locking block 307 is fixedly connected to the bottom end of the connecting rod 309. The locking block 307 matches the limiting hole 306. The elasticity of the limiting spring 308 can push the locking block 307 into the limiting hole 306 inside the limiting plate 304, which can conveniently limit the handle 305 and minimize the rotation of the handle 305 when the device is working. There are eight sets of limiting holes 306. The limiting holes 306 are evenly distributed in a ring shape at the top of the limiting plate 304.

[0034] Working principle: First, by passing the part to be cut through the inside of the two support frames 301, and then by rotating the handle 305, the threaded rod 303 can be rotated, which can push the clamping plate 302 to move downward, so as to easily fix the part to the support block 101 and minimize the displacement of the part when the support block 101 moves.

[0035] Secondly, when the handle 305 is rotated to the appropriate position, the elasticity of the limiting spring 308 can push the locking block 307 into the limiting hole 306 inside the limiting plate 304, which can conveniently limit the handle 305 and minimize the rotation of the handle 305 when the device is working, thus effectively improving the stability of the device.

[0036] Finally, the operation of the drive motor 104 can drive the lead screw 103 to rotate, which can drive the movable block 105 on the lead screw 103 to move. Through the transmission of the movable rod 102 and the support block 101, the fixed parts on the support block 101 can be moved, and the parts can be moved to the cutting head of the wire cutting machine, so as to facilitate the cutting and processing of the parts.
