Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool chuck technology, specifically to a machine tool chuck positioning device. Background Technology
[0002] A chuck is a mechanical device used on a machine tool to clamp workpieces. It is a machine tool accessory that uses the radial movement of movable jaws evenly distributed on the chuck to clamp and position the workpiece.
[0003] Machine tools require different chucks to process different parts in order to improve the safety of the machining process. However, existing chucks are generally fixed on the machine tool with bolts, which is cumbersome to disassemble and install, affecting the production efficiency of the machine tool. Therefore, we propose a new machine tool chuck positioning device. Utility Model Content
[0004] The purpose of this utility model is to provide a machine tool chuck positioning device, which solves the problem mentioned in the background art that the existing chuck is fixed on the machine tool by bolts, which is cumbersome to disassemble and install, and affects the production efficiency of the machine tool.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a machine tool chuck positioning device, comprising a machine tool chuck and a fixed base, wherein the fixed base is fixedly installed on a machine tool, and a groove for placing the machine tool chuck is formed on the upper surface of the fixed base, and a sliding groove is formed in the middle of the bottom of the groove, wherein a bidirectional threaded rod is rotatably installed in the sliding groove, and sliders are symmetrically arranged at both ends of the bidirectional threaded rod, and a locking block is fixedly installed at the upper end of each of the two sliders, and a matching locking groove is formed on the side wall of the machine tool chuck corresponding to the position of the locking block.
[0006] The machine tool chuck is placed in the groove of the fixed seat. The bidirectional threaded rod is used to control the slider to drive the chuck block to move. The chuck block and the chuck groove cooperate with each other to fix the machine tool chuck in place.
[0007] Preferably, the bidirectional threaded rod and the slide groove are arranged in parallel, and both ends of the bidirectional threaded rod are rotatably connected to the corresponding sidewalls of the slide groove. The parallel arrangement of the bidirectional threaded rod and the slide groove allows the slider to move horizontally along the slide groove.
[0008] Preferably, the front and rear sides of the two sliders are tightly fitted to the front and rear sidewalls of the slide groove, respectively, and the sliders and the slide groove are slidably connected. The tight fit between the sliders and the slide groove further prevents the sliders from shifting during movement.
[0009] Preferably, the two sliders have matching threaded holes at positions corresponding to the bidirectional threaded rod, and the sliders and the bidirectional threaded rod are threadedly connected. This threaded connection allows the sliders to move horizontally when the bidirectional threaded rod rotates.
[0010] Preferably, the two locking blocks have identical structures, and their opposite sides extend horizontally towards the center of the slide groove. When the two locking blocks approach each other, their extensions can be inserted into the corresponding slots to secure the machine tool chuck.
[0011] Preferably, a drive motor is fixedly installed on the side wall of the fixed base at one end of the bidirectional threaded rod. The end of the bidirectional threaded rod passes through the side wall of the fixed base and is fixedly connected to the output end of the drive motor. The drive motor controls the rotation of the bidirectional threaded rod, thereby controlling the sliding of the slider.
[0012] Preferably, an annular fixing block is fixedly installed at the bottom of the side wall of the fixing seat.
[0013] Preferably, the annular fixing block has several through holes for bolts to pass through, and the fixing seat is fixedly connected to the machine tool by bolts. The bolts are passed through the through holes and threaded into the machine tool, thereby fixing the annular fixing block onto the machine tool.
[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:
[0015] This invention features a fixed base with a locking block on it. The locking block is moved by a bidirectional threaded rod and a sliding drive. A matching slot is provided on the side of the machine tool chuck. The locking block and the slot cooperate to achieve a fixed installation of the chuck, avoiding the cumbersome installation and disassembly of the chuck and improving production efficiency.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a machine tool chuck positioning device, including a machine tool chuck 1 and a fixed base 2. The fixed base 2 is fixedly installed on the machine tool. The upper surface of the fixed base 2 is provided with a groove 3 for placing the machine tool chuck 1. A sliding groove 4 is provided in the middle of the bottom of the groove 3. A bidirectional threaded rod 5 is rotatably installed in the sliding groove 4. Slider 6 is symmetrically arranged at both ends of the bidirectional threaded rod 5. A locking block 7 is fixedly installed at the upper end of each of the two sliders 6. A matching locking groove 8 is provided on the side wall of the machine tool chuck 1 corresponding to the position of the locking block 7.
[0023] The bidirectional threaded rod 5 and the slide groove 4 are arranged in parallel, and the two ends of the bidirectional threaded rod 5 are rotatably connected to the corresponding side wall of the slide groove 4.
[0024] The front and rear sides of the two sliders 6 are tightly fitted to the front and rear sidewalls of the slide groove 4, and the sliders 6 and the slide groove 4 are slidably connected.
[0025] Two sliders 6 have matching threaded holes at the positions of the bidirectional threaded rod 5, and the sliders 6 and the bidirectional threaded rod 5 are threadedly connected.
[0026] The two card blocks 7 have the same structure, and their opposite sides extend horizontally towards the center of the slide groove 4.

[0030] Structural principle: When it is necessary to replace the machine tool chuck 1, first start the drive motor 9 to control the bidirectional threaded rod 5 to rotate, which drives the two sliders 6 to slide in opposite directions, so that the two clamping blocks 7 exit the slot 8 of the machine tool chuck 1 to be replaced. Remove the machine tool chuck 1 to be replaced, and then place the new machine tool chuck 1 into the groove 3 of the fixed seat 2. Control the drive motor 9 to rotate in the opposite direction, so that the two sliders 6 move closer to each other. Finally, the sliders 6 drive the clamping blocks 7 into the slot 8, which can clamp and fix the machine tool chuck. By setting the fixed seat 2, the machine tool chuck 1 can be quickly installed and removed, which improves production efficiency.
