Description
Technical Field
[0001] The utility model relates to the technical field of special-shaped clamps, in particular to a special-shaped clamp for a pick and drill sleeve numerically controlled lathe. Background Art
[0002] The pick is a tool that comes into direct contact with the workpiece. Its size and shape have a significant impact on the productivity of the pneumatic pick. The shape and length of the pick depends on the hardness of the ore layer to be penetrated. The harder the ore layer, the shorter the pick, and vice versa. The pick sleeve is a pipe sleeve used to fix the pick. Different styles of pick sleeves are used for different styles. The required special-shaped pick sleeves can be customized according to requirements.
[0003] When the fixture of the CNC lathe fixes the special-shaped pick drill sleeve, the bidirectional threaded rod is driven to rotate by the servo motor, and the bidirectional threaded rod drives the clamping frame to clamp the outer wall of the pick drill sleeve to fix the pick drill sleeve on the fixture. Due to the special shape of the special-shaped pick drill sleeve, it is difficult for the fixture to fully clamp the outer wall of the special-shaped pick drill sleeve, and the special-shaped pick drill sleeve is difficult to fit with the fixture, making it difficult to maintain a stable gap between the special-shaped pick drill sleeve and the fixture, which is inconvenient to use. Summary of the invention
[0004] The utility model aims to provide a special-shaped clamp for a pick drill sleeve CNC lathe to solve the problem that the clamps of CNC lathes currently on the market are difficult to stably clamp the special-shaped pick drill sleeves as mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special-shaped fixture for a pick and drill sleeve CNC lathe, comprising a base, a support plate, a support frame and a movable frame, a support plate being arranged at the top of the base, a support frame being welded to the top of the support plate, and two groups of movable frames being arranged at the top of the support frame.
[0006] Preferably, top covers are provided at the top ends of the two groups of movable racks, multiple groups of connecting rods extending to the outside are provided inside the two groups of movable racks, and springs are provided at one end of the multiple groups of connecting rods located inside the movable racks.
[0007] Preferably, a group of extrusion plates are provided inside the two groups of movable frames at one end of the spring, and the insides of the two groups of extrusion plates are provided with one-way threaded rods extending to the outside of the movable frames, and the ends of the two groups of one-way threaded rods away from the extrusion plates are welded with rotating blocks.
[0008] Preferably, a fixed plate is welded on the inner side of the support frame, and sliding grooves are provided on both sides of the top of the support frame, and sliding frames that pass through the sliding grooves and extend to the inside of the support frame are welded on the bottom ends of the two groups of movable frames, and a second servo motor is installed on one side of the support frame by bolts, and the output end of the second servo motor is connected to a bidirectional threaded rod that passes through the two groups of sliding frames through a coupling.
[0009] Preferably, a support shaft extending to the inside of the base is welded to the bottom end of the support plate, and a gear ring is welded to the bottom end of the support plate on the outside of the support shaft.
[0010] Preferably, a first servo motor is installed inside the base by bolts, and an output end of the first servo motor is connected to a gear located inside the gear ring through a coupling.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. When the clamp needs to clamp the special-shaped pick drill sleeve, the special-shaped pick drill sleeve is placed between two groups of moving frames, and the two groups of sliding frames and two groups of moving frames are driven to move by the second servo motor and the two-way threaded rod. The two groups of moving frames drive the connecting rods, springs, extrusion plates, one-way threaded rods and rotating blocks to move, so that multiple groups of connecting rods fit the outer wall of the special-shaped pick drill sleeve. The reaction force of the convex part of the special-shaped pick drill sleeve pushes the spring to compress and deform, so that the multiple groups of connecting rods clamp the special-shaped pick drill sleeve. The one-way threaded rod is driven by the rotating block to perform spiral movement inside the moving frame, and the one-way threaded rod pushes the extrusion plate and the spring to move. The extrusion plate pushes the spring to continuously deform, so that several groups of springs reach the maximum value, so that these groups of springs cannot be deformed, and then the connecting rod is stably supported, so that the connecting rod and the outer wall of the special-shaped pick drill sleeve are fully fitted, so that the special-shaped pick drill sleeve is fixed on the fixture, and the special-shaped pick drill sleeve is clamped by the connecting rod, which is convenient for the CNC machine tool to process the special-shaped pick drill sleeve.
[0013] 2. When the CNC lathe needs to adjust the processing angle of the special-shaped pick drill sleeve on the fixture, the first servo motor and the gear drive the gear ring, the support plate and the support shaft to rotate. The rotation of the support plate drives the support frame, the moving frame and the special-shaped pick drill sleeve to rotate, thereby adjusting the processing angle of the special-shaped pick drill sleeve, making it easier for the CNC lathe to process the special-shaped pick drill sleeve and providing convenience for the operator.
