Description

Technical Field

[0001] The utility model relates to the technical field of electric spark machines, in particular to a quick-release mechanism for a three-head electric spark machine. Background Art

[0002] As a high-precision processing equipment, EDM machine is widely used in the manufacturing industry for precision processing of hard materials. The Morse taper shank used in it carries out the conduction function between the electrode and the workpiece during the processing, ensuring the accuracy and stability of the processing.

[0003] However, the current EDM machines have certain inconveniences when it comes to maintenance and replacement of electrodes. The common method of removing the Morse taper shank requires using an inclined iron to knock it in order to release the shank from the spindle. This method requires two workers to operate at the same time: one person holds the inclined iron to knock, and the other person needs to take the taper shank. This operation method is cumbersome and time-consuming, greatly reducing the operating efficiency of the equipment and the operating comfort of the workers.

[0004] Therefore, those skilled in the art have proposed a three-head EDM machine quick-release mechanism. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a three-head electric spark machine quick release mechanism.

[0006] The technical solution of the utility model is as follows: a three-head electric spark machine quick-release mechanism, including a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are rotatably connected, the first connecting plate and the second connecting plate are both arranged in an arc structure, the outer sides of the first connecting plate and the second connecting plate are both fixedly connected with a sleeve box, the interior of the sleeve box is equidistantly slidably connected with a sliding rod, the tops of the corresponding sliding rods are both fixedly connected with a top plate, the outer sides of the corresponding sliding rods and located between the top plate and the sleeve box are both sleeved with a first spring, the bottoms of the corresponding sliding rods extend to the bottom of the sleeve box and are fixedly connected with a bottom adjustment box.

[0007] Through the above technical means, the first connecting plate and the second connecting plate are tied to the movable rod of the machine tool. When the slide bar moves, it will drive the bottom adjustment box to move and squeeze the first spring during the movement, thereby providing reset power for the slide bar through the first spring.

[0008] As a preferred embodiment, a polished rod is slidably connected inside the bottom adjustment box, one end of the polished rod is fixedly connected with a clamping block, and the clamping block is arranged in an arc-shaped structure.

[0009] Through the above technical means, the two clamping blocks cooperate with each other to clamp the drill chuck.

[0010] As a preferred embodiment, a second spring is sleeved on the outer side of the light rod and between the block and the bottom adjustment box, a key slot is opened on the outer side of the light rod, and a flat key matching the key slot is arranged inside the bottom adjustment box.

[0011] Through the above technical means, when in use, the drill chuck is clamped by two clamping blocks, and the drill chucks are of different sizes. Then, through the cooperation of the second spring and the polished rod, the two clamping blocks can clamp the drill chucks of different sizes.

[0012] As a preferred implementation, one end of the optical rod away from the clamping block is fixedly connected with a baffle.

[0013] Through the above technical means, the baffle is used to prevent the light rod from detaching.

[0014] As a preferred embodiment, a fixed block is fixedly connected to the outer side of the first connecting plate, a rotating screw is rotatably connected to the temporal part of the fixed block, and a locking block is fixedly connected to the outer side of the second connecting plate. The rotating screws extend into the interior of the locking block and are fixed by nuts.

[0015] By means of the above technical means, the screw is rotated into the locking block, and the first connecting plate and the second connecting plate are fixed to the movable column of the machine tool by nuts.

[0016] Compared with the prior art, the advantages and positive effects of the utility model are:

[0017] The utility model clamps the drill chuck by means of two clamping blocks. When the drill chuck of the electric spark needs to be replaced, the drill chuck will fall after being knocked by means of an inclined iron. When the drill chuck falls, the clamping block will be driven to move, thereby driving the sliding rod to move. When the sliding rod moves, the bottom adjusting box will be driven to move, thereby completing the clamping limit of the drill chuck and preventing it from falling. When the drill chuck is disassembled, the mechanism can clamp the drill chuck to prevent it from falling, thus reducing the risk of the drill chuck falling and eliminating the need for auxiliary personnel, thus making it more convenient for the staff to operate.
