Description

Technical Field

[0001] This utility model relates to the field of fixtures, specifically a tooling clamping fixture for CNC machining equipment. Background Technology

[0002] Tooling refers to the general term for various tools used in the manufacturing process, including cutting tools, fixtures, molds, and measuring tools. Fixtures are devices used in machining to fix the workpiece in a fixed position to facilitate machining, assembly, or inspection and measurement. In the machining process of CNC machining equipment, it is necessary to use tooling clamping fixtures to clamp and fix the workpiece. According to the CNC machining center tooling fixture disclosed in application number CN202320665366.5, it includes a device body; the top of the device body has four evenly distributed rectangular openings, and the inner wall of each rectangular opening is slidably connected to a connecting block. One end of two connecting blocks is fixedly connected to the same mounting base, and the top of the mounting base is provided with a clamping block. By using the first locking block, the arc spring, and the second locking block, when installing the clamping block, one end of the first locking block gradually approaches one end of the second locking block. Then, the second locking block rotates around its central axis under the action of the first locking block. When the bottom end of the clamping block is in complete contact with the top of the mounting base, each arc spring returns to its original deformation, and one end of the second locking block engages with one end of the first locking block. Under the action of each arc spring, the engagement is secure. The entire installation process is simple and quick, improving efficiency and reducing manpower consumption. However, the above description still has the following defects in actual use: the clamping structure lacks flexibility during use and cannot be adjusted according to the height required for workpiece processing. At the same time, frequently changing the clamping structure is cumbersome. Therefore, it is necessary to design a more practical tooling clamping fixture for CNC machining equipment.

The two sets of moving blocks 23, together with bushings 31, rotating shafts 33 and adjusting shafts 32, drive two mounting plates 34 to move. The two mounting plates 34, together with two sets of buffers 13, drive two arc-shaped clamping blocks 14 and rectangular clamping blocks 15 to move, thereby adjusting the height of the clamping structure of the CNC machining equipment and improving the flexibility of the device.

[0024] Please see Figure 3 The adjusting assembly 3 includes two bushings 31 and adjusting shafts 32 installed on opposite sides of two sets of moving blocks 23.

[0025] In practical use: the two adjusting handles 35 drive the two adjusting shafts 32 to rotate within the through holes 27 on the surfaces of the two moving blocks 23. The two adjusting shafts 32 drive the two rotating shafts 33 on the two mounting plates 34 to rotate within the inner walls of the two bushings 31. The two mounting plates 34, in conjunction with the two sets of buffer components 13, drive the two arc-shaped clamping blocks 14 and the rectangular clamping blocks 15 to rotate, thereby adjusting the angle of the clamping structure of the CNC machining equipment as needed. After the adjustment is completed, the two limiting pins 38 are inserted into the corresponding two limiting holes 37 and the docking holes 26, thereby limiting and fixing the two adjusting shafts 32 and the two moving blocks 23 to ensure the stability of the structure after adjustment.

[0037] In practical use: The control panel 113 is used to control the motor 18 and the electric push rod 22, which makes it easy for the CNC machining equipment to adjust the height and angle of the clamping structure.

[0038] In use, two sets of electric push rods 22 drive two sets of moving blocks 23 to move within the inner walls of two sets of fixed frames 21. The two sets of moving blocks 23 drive several sets of sliders 24 to move within the inner walls of several sets of sliding grooves 25, thereby limiting their movement. The two sets of moving blocks 23, in conjunction with bushings 31, rotating shafts 33, and adjusting shafts 32, drive two mounting plates 34 to move. The two mounting plates 34, in conjunction with two sets of buffers 13, drive two arc-shaped clamping blocks 14 and rectangular clamping blocks 15 to move, adjusting the height of the clamping structure of the CNC machining equipment. The two adjusting handles 35 drive the two adjusting shafts 32. The two adjusting shafts 32 rotate within the through holes 27 on the surfaces of the two moving blocks 23. The two adjusting shafts 32 drive the two rotating shafts 33 on the two mounting plates 34 to rotate within the inner walls of the two bushings 31. The two mounting plates 34, in conjunction with the two sets of buffers 13, drive the two arc-shaped clamping blocks 14 and the rectangular clamping blocks 15 to rotate. The angle of the clamping structure of the CNC machining equipment is adjusted as needed. After the adjustment is completed, the two limiting pins 38 are inserted into the corresponding two limiting holes 37 and the docking holes 26 to limit and fix the two adjusting shafts 32 and the two moving blocks 23 to ensure the stability of the structure after adjustment.
