[0001] This utility model belongs to the field of machine tool chuck technology, specifically a machine tool chuck for magnetic adsorption and positioning. Background Technology

[0002] Machine tool chucks are devices used to clamp and hold workpieces in machine tool processing. They are usually mounted on a three-jaw chuck or other fixtures. Their main function is to firmly fix the workpiece on the machine tool through clamping force so that machining operations such as turning, milling, and grinding can be performed. However, existing machine tool chucks are generally integrated with the three-jaw chuck, making them difficult to disassemble and replace. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a machine tool chuck with magnetic adsorption positioning, which solves the problem that existing machine tool chucks are generally integrated with three-jaw chucks, making them difficult to disassemble and replace.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a machine tool chuck for magnetic adsorption positioning, comprising a machine tool chuck body, a T-shaped strip fixedly connected to the bottom of the machine tool chuck body, a movable plate provided at the bottom of the machine tool chuck body, a T-shaped hole provided on the movable plate, the T-shaped hole being a blind hole, the T-shaped strip being located inside the T-shaped hole, and a first fixing block fixedly connected to one side of the machine tool chuck body, the first fixing block having a through hole;

[0005] A second fixing block is fixedly connected to one side of the movable plate. A first threaded hole is provided on the second fixing block. A screw is provided inside the through hole. The screw is threadedly connected to the first threaded hole. A spiral groove is provided at the bottom of the movable plate. A frame is fixedly connected to both the front and back of the movable plate. Several rollers are rotatably connected inside the frame.

[0007] As a further embodiment of this utility model: the machine tool chuck body has two second threaded holes, the second threaded holes being positioned corresponding to the countersunk holes.

[0008] As a further embodiment of this utility model: a screw is provided inside the countersunk hole, and the screw is threadedly connected inside the second threaded hole.

[0009] As a further embodiment of this utility model: a nut is fixedly connected to the top of the screw, and the nut has several grooves.

[0010] As a further embodiment of this utility model: the first fixing block is located on top of the second fixing block, and the magnetic plate is located on top of the movable plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This magnetically adsorbed machine tool chuck, by setting a T-shaped strip, a T-shaped hole, a nut, a screw, a through hole, and a first threaded hole, allows for easy removal of the chuck body from the moving plate. First, the nut is rotated to rotate the screw, disengaging it from the first threaded hole and releasing the chuck body from its fixed position. The chuck body can then be slid to disassemble it. When installing the chuck body, the T-shaped strip is placed inside the T-shaped hole, and the chuck body is slid. When the through hole aligns with the first threaded hole, the screw is placed inside the through hole and screwed into the first threaded hole, thus fixing the chuck body in place and completing the installation. This machine tool chuck facilitates easy disassembly and installation, making it convenient for replacement.

[0013] 2. This magnetic adsorption positioning machine tool chuck, by setting a magnetic plate, a second threaded hole, a countersunk hole, and a screw, allows for easy removal of the magnetic plate when it needs to be disassembled. When the magnetic plate needs to be installed, it is placed against one side of the machine tool chuck body, aligning the countersunk hole with the second threaded hole. The screw is then placed inside the countersunk hole and screwed into the second threaded hole to fix the magnetic plate in place. This completes the installation of the magnetic plate. By using the magnetic plate for magnetic adsorption positioning of the workpiece, combined with the clamping action of the machine tool chuck body, the stability of the workpiece is effectively improved. Furthermore, it facilitates the disassembly and installation of the magnetic plate, making it easy to replace. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a machine tool chuck with magnetic adsorption positioning, including a machine tool chuck body 1, a T-shaped strip 13 fixedly connected to the bottom of the machine tool chuck body 1, a movable plate 2 provided at the bottom of the machine tool chuck body 1, a magnetic plate 3 provided on one side of the machine tool chuck body 1, two countersunk holes 16 provided on the magnetic plate 3, and a T-shaped hole 14 provided on the movable plate 2. The T-shaped hole 14 is a blind hole. Because of the T-shaped strip 13 and the T-shaped hole 14, and because the T-shaped hole 14 is a blind hole, the T-shaped hole 14 can limit the T-shaped strip 13 and the machine tool chuck body 1, thereby improving the stability of the machine tool chuck body 1.

[0021] T-shaped bar 13 is located inside T-shaped hole 14. A first fixing block 6 is fixedly connected to one side of the machine tool chuck body 1. A through hole 7 is opened on the first fixing block 6. A second fixing block 8 is fixedly connected to one side of the moving plate 2. A first threaded hole 9 is opened on the second fixing block 8. A screw 4 is installed inside the through hole 7. A nut 5 is fixedly connected to the top of the screw 4. Several grooves are opened on the nut 5. Because several grooves are opened on the nut 5, friction can be increased, making it easier for personnel to rotate the nut 5 and improving the ease of operation.

[0022] The screw 4 is threaded into the first threaded hole 9. The bottom of the movable plate 2 is provided with a spiral groove 10. The front and back of the movable plate 2 are fixedly connected with a frame 11. The first fixing block 6 is located on top of the second fixing block 8. The magnetic plate 3 is located on top of the movable plate 2.

[0023] The frame 11 has several rollers 12 rotatably connected inside. The rollers 12 can reduce friction and improve the smoothness of the movement of the entire machine tool chuck. The machine tool chuck body 1 has two second threaded holes 15, which correspond to the countersunk holes 16. Screws 17 are installed inside the countersunk holes 16 and are threaded into the second threaded holes 15.

[0024] The working principle of this utility model is as follows:

[0025] In use, the movable plate 2 is installed inside the three-jaw chuck through the spiral groove 10, and the roller 12 is in contact with the inner wall of the sliding groove on the three-jaw chuck. When it is necessary to remove the machine tool jaw body 1 from the movable plate 2, first rotate the nut 5 to drive the screw 4 to rotate, so that the screw 4 is disengaged from the first threaded hole 9, thereby releasing the fixed state of the machine tool jaw body 1. At this time, the machine tool jaw body 1 can be slid to remove the machine tool jaw body 1. When it is necessary to install the machine tool jaw body 1, place the T-shaped strip 13 inside the T-shaped hole 14 and slide the machine tool jaw body 1. When the through hole 7 is aligned with the first threaded hole 9, place the screw 4 inside the through hole 7 and screw the screw 4 into the first threaded hole 9, thereby fixing the machine tool jaw body 1 and completing the installation of the machine tool jaw body 1.

[0026] When it is necessary to disassemble the magnetic plate 3, turn the screw 17 to disengage the screw 17 from the second threaded hole 15, thereby releasing the magnetic plate 3 from its fixed state. At this time, the magnetic plate 3 can be disassembled. When it is necessary to install the magnetic plate 3, place the magnetic plate 3 against one side of the machine tool chuck body 1, so that the countersunk hole 16 is aligned with the second threaded hole 15. Then, place the screw 17 inside the countersunk hole 16 and screw the screw 17 into the second threaded hole 15 to fix the magnetic plate 3, thus completing the installation of the magnetic plate 3.
