Description

Technical Field

[0001] This utility model relates to the field of electrode clamping technology, and in particular to a quick clamping fixture for lowering the electrode surface. Background Technology

[0002] Because electrodes need to be reused, an electrode is often reused about 15 times. After each use, the electrode surface needs to be milled, so the workload of milling the electrode surface is quite heavy.

[0003] However, existing processing methods can only use traditional milling machines. Traditional vises can only hold the electrode base. If the depth of cut is too large, the electrode head is prone to shaking. In addition, manual vise clamping and manual feed milling have slow processing efficiency and low production efficiency.

The output end of the positioning cylinder is positioned corresponding to the clamping position of the U-shaped gripper. The positioning cylinder controls the limiting block to restrict the workpiece positioning position of the U-shaped gripper clamping position. A self-locking device is connected to the cylinder fixing block.

[0006] Preferably, the self-locking device includes a rack, a connecting block, and a limiting fixing block. The rack is fixedly mounted parallel to the base plate of the fixture and located below the moving groove. The connecting block is fixedly connected to the cylinder fixing block, and the end of the connecting block is hinged to the limiting fixing block. The end of the limiting fixing block and the rack form a ratchet structure.

[0007] Preferably, a top rod is hinged to the limiting and fixing block.

[0008] Preferably, a pressure plate is fixedly installed on the upper part of the movable groove by bolts.

[0009] Preferably, the movable side of the U-shaped gripper and the fixed side of the U-shaped gripper are both L-shaped.

[0010] Preferably, the positioning cylinder fixing plate has multiple sets of adjustment holes evenly provided from top to bottom, and the positioning cylinder fixing block is fixedly connected to one set of adjustment holes by bolts.

[0011] Preferably, the positioning cylinder fixing plate has an oblong hole, and the positioning cylinder fixing plate is fastened to the fixture bearing base plate by bolts passing through the oblong hole.

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example: Figures 1-5As shown, a quick-clamping fixture for electrode lowering includes a base plate 1. A fixture support base plate 3 is fixedly connected to the base plate via a support column 2. A movable groove is formed on one side of the fixture support base plate, and a cylinder fixing block 4 is slidably connected to the movable groove. A clamping cylinder 5 is fixedly connected to the cylinder fixing block. A U-shaped gripper is provided at the front end of the clamping cylinder. The U-shaped gripper includes a movable side 6 and a fixed side 7. The output end of the clamping cylinder is fixedly connected to the movable side of the U-shaped gripper, and the fixed side of the U-shaped gripper is fixedly connected to the fixture. A positioning cylinder fixing plate 9 is vertically installed between the base plate and the fixture base plate on the bearing base plate. A positioning cylinder fixing block 10 is fixedly connected to the positioning cylinder fixing plate. A positioning cylinder 11 is fixedly installed on the positioning cylinder fixing block. One end of the positioning cylinder output end is movably connected to one end of the limiting block 13. The other end of the limiting block is hinged to the fixture base plate. The positioning cylinder output end is set to the clamping position of the U-shaped gripper. The positioning cylinder controls the limiting block to limit the clamping position of the U-shaped gripper and the workpiece positioning position. A self-locking device is connected to the cylinder fixing block.

[0017] The self-locking device includes a rack 14, a connecting block 20, and a limiting fixing block 21. The rack is fixedly mounted on the jig bearing base plate in parallel by rack fixing bolts 23, located below the moving groove. The connecting block is fixedly connected to the cylinder fixing block, and the end of the connecting block is hinged to the limiting fixing block. The end of the limiting fixing block and the rack form a ratchet structure.

[0018] A top rod 22 is hinged to the limiting and fixing block. A pressure plate 15 is fixedly installed on the upper part of the moving groove by a pressure plate fixing bolt 19. The movable side of the U-shaped gripper and the fixed side of the U-shaped gripper are both L-shaped.

[0019] Multiple sets of adjustment holes 24 are evenly provided from top to bottom on the positioning cylinder fixing plate, and the positioning cylinder fixing block is fixedly connected to one set of adjustment holes by bolts.

[0020] The positioning cylinder fixing plate has an oblong hole 25, and the positioning cylinder fixing plate is fastened to the fixture bearing base plate by bolts passing through the oblong hole.

[0021] The U-shaped gripper is fixedly connected to the fixture base plate by a fixing bolt 18. A top block 12 is fixedly connected to the output end of the positioning cylinder, and the top block is movably connected to one end of the limit block.

[0022] The support column and the base plate are fixedly connected by the base plate fixing bolts 16, and the support column and the fixture bearing base plate are fixedly connected by the bearing base plate fixing bolts 17.

[0023] This invention replaces the traditional vise clamping method with cylinder clamping, which results in faster clamping speed. The side-positioning cylinder ensures accurate and repeatable positioning of each electrode, reducing labor intensity and improving processing efficiency.

[0024] When machining electrodes with different strokes, the self-locking device of the fixture is very easy to operate. When the electrode stroke needs to be adjusted forward, simply push the cylinder fixing block to adjust it to the designated position. The limit fixing block will automatically lock by gravity. When the electrode stroke needs to be adjusted backward, manually push the push rod and the cylinder will move backward. Once it reaches the appropriate position, lower the push rod. The machining efficiency is high, making it particularly suitable for batch processing of parts.

[0025] When clamping, the motor is placed on the platform of the U-shaped gripper. The positioning cylinder switch is turned on to position the electrode 8. After the clamping cylinder is opened and clamped, the positioning cylinder is returned to its original position to complete the clamping. After processing, the electrode can be taken out simply by releasing the clamping cylinder, which greatly improves the clamping speed and repeatability accuracy.
