Description

[0002] Turning and boring processing refers to a common processing method of machining mechanical workpieces using CNC machine tools. When performing turning and boring processing, it is necessary to first use a fixture to fix the mechanical workpiece to ensure its stability during the processing process and avoid the problem of poor processing effect due to the loose fixation of the mechanical workpiece. However, during processing, due to the variable size of mechanical workpieces and the various specific processing methods, it is necessary to select the corresponding fixture according to the specific processing needs. The existing turning and boring fixtures are mostly connected to the machine tools by bolts. Frequent disassembly and assembly can easily cause the bolts and screw holes to be stripped, affecting the subsequent fixing effect. In addition, the installation area on the machine tool used to fix the turning and boring fixture is also unchanged. This leads to the problem that when the size of the boring fixture used is significantly different from the installation area, it will be impossible to install or inconvenient to install. Therefore, it is necessary to design a boring fixture that is easy to disassemble and install.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1-5 A boring fixture that is easy to disassemble and install, including a machine tool body 1 and a fixture body 3 fixedly installed on a fixture mounting seat 2, the machine tool body 1 is provided with two moving cavities 4, and the two moving cavities 4 are symmetrically arranged, the two moving cavities 4 are slidably connected with moving seats 5, the two moving seats 5 are both installed with two connecting seats 6 through a control mechanism, the two moving seats 5 and each connecting seat 6 are provided with a socket 7, a plurality of plug plates 8 are fixedly installed at the lower end of the fixture mounting seat 2, and each plug plate 8 is respectively matched with a corresponding plug hole 7;

[0027] It is worth noting that:

[0028] 1. Through the cooperation of the plug plate 8 and the socket 7, the fixture mounting seat 2 can be positioned on the machine tool body 1. Since the two movable seats 5 are sliding on the machine tool body 1, the distance between the two movable seats 5 can be adjusted according to the specific size of the fixture mounting seat 2, so that fixture mounting seats 2 of different sizes can be effectively fixed on the machine tool body 1, the installation application range is improved, and the problem of being unable to install or difficult to install due to the large deviation of the installation area between the fixture mounting seat 2 and the machine tool body 1 is avoided.

[0029] 2. The movable seat 5, the connecting seat 6 and the plug plate 8 are all made of hard metal materials (the hard metal material can be alloy steel).

Through the cooperation of the screw rod 14 and the positioning column 11, when the rotating rod 13 is rotated, the positioning column 11 can be moved in the receiving groove 10. Therefore, when the plug plate 8 is plugged into the socket 7, the positioning column 11 can be moved and inserted into the positioning groove 9.

When the movable motor 15 is working, the rotation of the rotating rod 13 can be controlled by the design of the chain transmission structure 16. At this time, the position of the positioning column 11 in the accommodating groove 10 can be adjusted, which is convenient for controlling the fixing relationship between the clamp mounting seat 2 and the movable seat 5. There is no need to use bolts to fix the clamp mounting seat 2, which can effectively avoid the problem of slipping of bolts or screw holes caused by frequent disassembly and assembly, affecting the subsequent fixing effect of the clamp mounting seat 2, and the disassembly and assembly method is also simpler.

[0034] 7. The control mechanism consists of a mounting block 22, a bidirectional lead screw 23, a control motor 25, a fixed gear 26, a connecting gear ring 27 and two connecting blocks 24. The mounting block 22 is fixedly mounted on the side wall of the moving seat 5, the bidirectional lead screw 23 is rotatably connected to the mounting block 22, the two connecting blocks 24 are respectively threadedly connected to the two ends of the bidirectional lead screw 23, and the two connecting blocks 24 are respectively fixedly connected to the two connecting seats 6, the control motor 25 is fixedly mounted on the mounting block 22, the fixed gear 26 is fixedly connected to the output end of the control motor 25 through a fixed shaft, and the connecting gear ring 27 is fixedly mounted on On the bidirectional lead screw 23, the connecting gear ring 27 is meshed with the fixed gear 26. Through the meshing action of the fixed gear 26 and the connecting gear ring 27, the bidirectional lead screw 23 can be driven to rotate when the control motor 25 is working, and then the two connecting blocks 24 can drive the two connecting seats 6 to move closer or farther away from each other. At this time, the distance between the two connecting seats 6 and the moving seat 5 changes, and the distance between the two sockets 7 thereon will also change, so that it can be effectively aligned and connected with the plug plates 8 at different positions at the lower end of the clamp mounting seat 2, further improving the connection effect between the device and clamp mounting seats 2 of different sizes.

[0035] 8. An adjustment mechanism is installed on the machine tool body 1, and the adjustment mechanism cooperates with the moving seat 5. The adjustment mechanism consists of an adjustment motor 21, a bidirectional screw rod 20, a through hole 19, two adjustment slots 18 and two adjustment rods 17. The adjustment motor 21 is fixedly installed on the side wall of the machine tool body 1, and the bidirectional screw rod 20 is rotatably connected to the machine tool body 1, and the bidirectional screw rod 20 is fixedly connected to the output end of the adjustment motor 21.
