Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical discharge machining equipment, and in particular to the machine tool structure of an electrical discharge machining machine for machining motor parts. Background Technology
[0002] To prevent the dielectric fluid in the working tank of an EDM machine from splashing out during the forming process and to reduce the entry of external dust and impurities into the dielectric fluid, existing EDM machines are equipped with protective devices to address these issues. These devices can slide from one side of the working tank to the top of the working tank to provide shielding and lock the position without interfering with the machine head. While this structure solves the problems, it is relatively complex, requires installation in multiple locations, occupies a lot of horizontal space, and is time-consuming to operate. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a machine tool structure for an electrical discharge machining (EDM) machine for processing motor parts. While solving the problems of existing technologies, it has a simpler structure, occupies less space, and is easy and time-saving to operate.
[0004] The technical solution of the present invention is as follows:
[0005] A machine tool structure for an electrical discharge machining (EDM) machine for machining motor parts includes a working groove and a pair of symmetrical shielding structures disposed on both sides of the top of the working groove. The shielding structure includes a connecting block, a connecting shaft, and a baffle. There are two connecting blocks, which are respectively disposed on both sides of the working groove. A strip-shaped connecting hole is opened in the middle of the connecting block. The two ends of the connecting shaft are respectively disposed in the strip-shaped connecting hole. The baffle is disposed on one side of the connecting shaft. A semi-circular groove is opened in the middle of the opposite side of the two baffles.
[0006] In a further technical solution, the connecting block has a movable hole on the side away from the working groove that connects to the strip-shaped connecting hole. A limiting push rod passes through the movable hole, and a push block that connects to the limiting push rod is provided in the strip-shaped connecting hole. The top and bottom sides of the push block are slidably connected to the top and bottom sides of the strip-shaped connecting hole, respectively. A spring is sleeved on the outside of the limiting push rod located inside the strip-shaped connecting hole.
[0007] In a further technical solution, an arc-shaped rubber soft edge is provided along the inner side of the groove.
[0008] In a further technical solution, one of the baffles is provided with an exhaust connector, and a detachable exhaust hose is connected to the exhaust connector.
[0009] In a further technical solution, the baffle is made of a transparent material.
[0010] The beneficial effects of this invention are:
[0011] 1. The shielding structure prevents the dielectric fluid in the working tank of the EDM machine from splashing out during the forming process, reducing the entry of external dust and impurities into the dielectric fluid. The shielding front baffle can be flipped to fit against the side wall of the working tank, reducing the horizontal space occupation. When shielding, the baffle can be flipped directly. The connecting shaft is located on the side away from the middle of the working tank, which can keep the baffle away from the working head above the working tank and avoid interference with the working head when flipping the baffle. The connecting shaft rotates relative to the connecting block, flipping the two baffles to the top of the working tank. The strip-shaped connecting hole provides space for the horizontal movement of the connecting shaft. The position of the two baffles can be adjusted appropriately according to the position of the working head. The two baffles can be pushed to move towards each other until they fit together, so that the two semi-circular grooves combine to form a through hole that allows the working head to pass through.
[0012] 2. By setting up movable holes, limit push rods, push blocks and springs, the baffle can be automatically assembled under the action of spring force after it flips over;
[0013] 3. The soft rubber edge inside the groove can be bent to fit the top side of the working head, avoiding a large gap between the groove and the working head;
[0014] 4. Install exhaust connectors and exhaust hoses to facilitate the discharge of gas from the working tank;
[0015] 5. The baffle is made of transparent material to facilitate observation of the working tank. Attached Figure Description

[0022] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0023] Example:
[0024] like Figures 1-4 As shown, the machine tool structure of an EDM machine for machining motor parts includes a working groove 10 and a pair of symmetrically arranged shielding structures on both sides of the top of the working groove 10. Each shielding structure includes a connecting block 20, a connecting shaft 30, and a baffle 40. Two connecting blocks 20 are provided, which can be welded to both sides of the working groove 10. A strip-shaped connecting hole 21 is provided in the middle of each connecting block 20. Both ends of the connecting shaft 30 are located within the strip-shaped connecting holes 21 on both sides. The baffle 40 is located on one side of the connecting shaft 30. A semi-circular groove 41 is provided in the middle of the opposite side of each of the two baffles 40. The through hole formed by the combination is larger than the size of the working head, and the diameter of the connecting shaft 30 matches the width of the strip connecting hole 21; the side of the connecting block 20 away from the working groove 10 is provided with a movable hole that connects to the strip connecting hole 21, and a limiting push rod 51 is inserted in the movable hole. The strip connecting hole 21 is provided with a push block 52 that connects to the limiting push rod 51. The side of the push block 52 close to the connecting shaft 30 can be provided with a groove that matches the connecting shaft 30. The top and bottom sides of the push block 52 are respectively slidably connected to the top and bottom sides of the strip connecting hole 21. A spring 53 is sleeved on the outside of the limiting push rod 51 located inside the strip connecting hole 21.
[0025] The working principle of the above technical solution is as follows:
[0026] When blocking, the baffle 40 can be flipped directly, and the connecting shaft 30 can be pushed to compress the spring 53 on the back of the push block 52, so that the connecting shaft 30 is in the strip-shaped connecting hole 21 away from the middle of the working groove 10. This allows the baffle 40 to be away from the working head above the working groove 10, avoiding interference with the working head when the baffle 40 is flipped. The connecting shaft 30 rotates relative to the connecting block 20, flipping the two baffles 40 to the top of the working groove 10. The strip-shaped connecting hole 21 provides space for the connecting shaft 30 to move horizontally. The position of the two baffles 40 can be adjusted appropriately according to the position of the working head. When the baffle 40 flipped to the top of the working groove 10 is released, the spring 53 rebounds and pushes the push block 52, thereby pushing the two baffles 40 to move towards each other, so that the two semi-circular grooves 41 combine to form a through hole that allows the working head to pass through.
[0027] In another embodiment, such as Figure 2 As shown, an arc-shaped rubber soft edge 42 is provided along the inner side of the groove 41. The rubber soft edge 42 in the groove 41 can be bent to fit the top side of the working head, avoiding a large gap between the groove 41 and the working head.
[0028] In another embodiment, such as Figure 1-2 As shown, one of the baffles 40 is equipped with an exhaust connector 43, and a detachable exhaust hose 44 is connected to the exhaust connector 43. The exhaust connector 43 and the exhaust hose 44 facilitate the discharge of gas from the working tank 10.
[0029] In another embodiment, the baffle 40 is made of transparent material to facilitate observation of the working groove 10.
[0030] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
