[0001] The utility model relates to the technical field of numerically controlled milling machines, in particular to a tool connection mechanism. Background Art

[0002] With the rapid development of the manufacturing industry, CNC milling machines play a vital role in various types of mechanical processing. As one of the core components of CNC milling machines, the performance and replacement efficiency of the tool directly affect the efficiency and quality of the entire processing process.

[0003] However, the tool fixing mechanism in the prior art often fails to ensure that the tool does not rotate when fixed, resulting in inaccurate tool angles and affecting processing accuracy. At the same time, the prior art lacks an effective limiter, and the tool is prone to sliding up and down during installation, increasing the risk of the tool falling and affecting the safety and stability of the operation. Due to the above problems, the tool installation stability and accuracy in the prior art are low, resulting in errors during the processing, affecting the final processing quality. Therefore, improvements are needed. Utility Model Content

[0014] Beneficial effects of the utility model:

[0015] The present invention needs to be installed at the rear of the CNC milling machine and in front of the chain tool magazine. When the CNC milling machine needs to change the tool, the chain tool magazine at the rear takes out the tool and then clamps the new tool on the clamping claw. The present invention takes the new tool and then moves it to the gantry close to the CNC milling machine. The tool picker takes out the milling cutter that needs to be replaced from the processing head and clamps it on another set of clamping claws. The rotary cylinder then drives the clamping claws to rotate 180 degrees and rotates the new tool to the side of the tool picker. The tool picker then obtains the new tool and then the old tool is sent back to the chain tool magazine for storage. The new and old tools here are not worn tools, but tools of different specifications that are used when different structures need to be processed. At the same time, the motor drives the lead screw to rotate. At this time, since the connecting block is provided with a thread inside, it can drive the connecting block to move. The connecting block can then drive the fixed frame to move back and forth to adjust the distance of the connection. The slider slides with the slide rail on the mounting surface, and the motor is fixed on the mounting surface. When the tool body is engaged, the tool body can be pushed into the clamping groove of the clamping jaw. At this time, the clamping jaw undergoes elastic deformation to clamp the tool body. At the same time, the clamping strip can be clamped into the annular groove on the tool body, and the abutment block can be inserted into the abutment groove. The abutment block is clamped into the abutment groove, which can effectively prevent the tool body from rotating when fixed, thereby ensuring that the angle of the tool body is correct, and the clamping strip can effectively limit the upper and lower positions of the tool body to prevent the tool body from slipping. The utility model can ensure that the tool body will not rotate when fixed through the design of the clamping strip and the abutment block, thereby ensuring that the angle of the tool body is correct. At the same time, the clamping strip can limit the upper and lower positions of the tool body to prevent the tool body from slipping, thereby improving the stability and accuracy of the tool body installation.

[0025] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0026] Please refer to Figure 1-Figure 7The utility model proposes a tool connection mechanism, including a fixed frame 1, a driving mechanism 2 is provided on the surface of the fixed frame 1, a rotating cylinder 3 is provided on the inner wall of the fixed frame 1, and a tool fixing mechanism 4 is installed on the output end of the rotating cylinder 3. The fixed frame 1 can be made of steel material, which has good strength and durability. A receiving plate 5 is fixedly installed on the side of the fixed frame 1, and the receiving plate 5 can catch the oil dripping from the surface of the tool body 406. A baffle 6 is fixedly installed on the side of the receiving plate 5, and the baffle 6 can prevent the oil from splashing. The receiving plate 5 and the baffle 6 can be fixed to the fixed frame 1 by bolt connection, which is convenient to install and simple to maintain. The tool fixing mechanism 4 includes a connecting plate 401, which is mounted on the output end of the rotary cylinder 3. A clamping jaw 402 is fixedly mounted on the side of the connecting plate 401. The clamping jaws 402 are symmetrically distributed on both sides of the connecting plate 401. A clamping groove 403 is provided on the inner side of the clamping jaw 402. A clamping strip 404 and an abutting block 405 are fixedly mounted on the inner wall of the clamping groove 403. A tool body 406 is provided on the inner wall of the clamping groove 403. An annular groove 407 and an abutting groove 408 are provided on the surface of the tool body 406. The annular groove 407 is adapted to the size of the clamping strip 404. There are two groups of abutting grooves 408, which are symmetrically distributed on the inner wall of the clamping groove 403. The connecting plate 401 and the clamping jaw 402 can be made of high-strength alloy material, have good wear resistance and durability, and can withstand high-frequency use.

[0027] The driving mechanism 2 includes a connecting block 201, which is fixedly mounted on the bottom surface of the fixing frame 1. A motor 202 is provided on one side of the fixing frame 1. A screw rod 203 is installed on the output end of the motor 202. A thread is provided inside the connecting block 201, and the thread is meshed with the screw rod 203. A blocking block 204 is fixedly mounted on one end of the screw rod 203. A slider 205 is fixedly mounted on the bottom surface of the fixing frame 1. The motor 202 is fixed to the fixing frame 1 by bolts. The threaded connection between the screw rod 203 and the connecting block 201 can ensure the stability and accuracy of the transmission. The slider 205 can slide on the slide rail on the mounting surface, ensuring the mobility of the overall structure.

[0028] In this embodiment, it needs to be installed at the rear of the CNC milling machine and in front of the chain tool magazine. When the CNC milling machine needs to change the tool, the chain tool magazine at the rear takes out the tool and then clamps the new tool on the clamping claw 402. The new tool is taken away by this application and then moved to the gantry close to the CNC milling machine. The tool taker takes out the milling cutter that needs to be replaced from the processing head and clamps it on another set of clamping claws 402. Then the rotating cylinder 3 drives the clamping claws 402 to rotate 180 degrees, and the new tool is rotated to the side of the tool taker, and the tool taker obtains the new tool. Then the old knife is sent back to the chain tool magazine for storage. The new and old knives here are not worn knives, but knives of different specifications that are used when different structures need to be processed. At the same time, the motor 202 drives the lead screw 203 to rotate. At this time, since the connection block 201 is provided with a thread inside, it can drive the connection block 201 to move. The connection block 201 can then drive the fixed frame 1 to move forward and backward to adjust the connection distance. The slider 205 slides with the slide rail on the installation surface, and the motor 202 is fixed. On the mounting surface, when the tool body 406 is engaged, the tool body 406 can be pushed into the clamping groove 403 of the clamping jaw 402. At this time, the clamping jaw 402 undergoes elastic deformation to clamp the tool body 406. At the same time, the clamping strip 404 can be inserted into the annular groove 407 on the tool body 406, and the abutment block 405 can be inserted into the abutment groove 408. The abutment block 405 is inserted into the abutment groove 408, which can effectively prevent the tool body 406 from rotating when it is fixed, thereby ensuring the angle of the tool body 406. The angle of the tool body 406 is correct, and the clamping strip 404 can effectively limit the upper and lower positions of the tool body 406 to prevent the tool body 406 from slipping. The utility model can ensure that the tool body 406 will not rotate when fixed through the design of the clamping strip 404 and the abutment block 405, thereby ensuring that the angle of the tool body 406 is correct. At the same time, the clamping strip 404 can limit the upper and lower positions of the tool body 406 to prevent the tool body 406 from slipping, thereby improving the stability and accuracy of the installation of the tool body 406.

[0029] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
