Technical Field

[0001] The present invention relates to the technical field of machine tool processing, and in particular to a novel deep groove processing shock absorbing tool. Background Art

[0002] Machine tools (English name: machine tool) refer to machines that manufacture machines and machinery. Machine tools play an important role in the construction of national economic modernization. Lathes are machine tools that mainly use turning tools to turn rotating workpieces.

[0003] During cutting processing, the protruding part of the cutting blade is long and the thickness is very thin, resulting in low strength of the tool body, which cannot suppress the vibration generated by the cutting blade during processing. Due to the influence of vibration, the cutting blade is easily unstable during processing, and the qualified rate of the processed workpiece is reduced. Therefore, this problem has not been solved. We propose a new deep groove processing shock-absorbing tool. Summary of the invention

The shock absorbing device includes a shock absorbing block and a shock absorbing assembly. The shock absorbing block is connected to the cutter head through the shock absorbing assembly and is used for making the shock absorbing assembly have elastic deformation when the vibration is subjected to external force, thereby reducing the vibration of the cutter head.

[0006] According to the technical solution provided in the embodiment of the present application, a mounting groove is provided on the side wall of the cutter head away from the cutter handle in the first direction, and a raised platform coaxial with the mounting groove is provided on the inner wall of the cutter head close to the cutter handle in the first direction; the first direction is perpendicular to the third direction.

[0007] According to the technical solution provided in the embodiment of the present application, a first accommodating portion is provided on the circumferential side wall of the raised platform at one end close to the knife handle along the first direction, and a second accommodating portion is provided on the edge of the side wall of the mounting groove close to the knife handle in the first direction; the shock absorbing assembly includes a first shock absorbing member and a second shock absorbing member, the first shock absorbing member is arranged in the first accommodating portion, and the second shock absorbing member is arranged in the second accommodating portion.

[0009] According to the technical solution provided in the embodiment of the present application, a second accommodating groove coaxial with the first accommodating groove is arranged on the side wall of the shock absorbing block away from the knife handle in the first direction, a first limiting portion is arranged on the circumferential inner wall of the second accommodating groove close to the edge of the first accommodating groove, and the shock absorbing assembly also includes a third shock absorbing member, and the third shock absorbing member is arranged in the first limiting portion.

[0010] According to the technical solution provided in the embodiment of the present application, the density of the shock absorbing block is greater than the density of the cutter head, and the shock absorbing block abuts against the first shock absorbing member, the second shock absorbing member and the third shock absorbing member, so that the first shock absorbing member, the second shock absorbing member and the third shock absorbing member have elastic deformation.

[0011] According to the technical solution provided in the embodiment of the present application, a first mounting hole is opened on the shock-absorbing block along the first direction, and the first mounting hole and the first accommodating groove are coaxially arranged, the two ends of the first mounting hole are respectively connected to the first accommodating groove and the second accommodating groove, and a second mounting hole is opened on the raised platform along the first direction, and the second mounting hole and the first mounting hole are coaxially arranged, and the first mounting member passes through the first mounting hole and extends into the second mounting hole.

The shock-absorbing block abuts against the shock-absorbing assembly, so that the shock-absorbing assembly has elastic deformation. Therefore, when the device is used to perform turning processing on a workpiece, the vibration generated by the processing is transmitted to the shock-absorbing device. Since the shock-absorbing assembly has elastic deformation, when vibration occurs, the shock-absorbing block squeezes the shock-absorbing assembly, and the kinetic energy of the vibration is converted into the internal energy of the shock-absorbing assembly, and finally converted into heat energy and dissipated, thereby achieving the shock-absorbing effect of the tool head, ensuring the overall stability of the device during processing, improving the processing quality, ensuring the qualified rate of the workpiece, avoiding scrap, and saving costs.

a second limiting portion is provided on the circumferential edge of the side wall of the shock absorbing block 4 close to the knife handle 1 in the first direction corresponding to the second shock absorbing member 8; Thus, the first limiting portion can abut against and squeeze the first shock absorbing member 7, and the second limiting portion can abut against and squeeze the second shock absorbing member 8, so that the first shock absorbing member 7 and the second shock absorbing member 8 have a certain elastic deformation; Furthermore, the damping block 4 is provided with a second receiving groove 10 coaxial with the first receiving groove 9 on the side wall away from the handle 1 in the first direction, and a third receiving portion is provided on the circumferential inner wall of the second receiving groove 10 near the edge of the first receiving groove 9;

It should be noted that the first mounting member 14 has a mounting head, which presses the third shock absorbing member 11, and the second receiving groove 10 is equivalent to a countersunk hole, which is used to hide the mounting head; It should be noted that the density of the shock absorbing block 4 is greater than the density of the cutter head 2 , which improves the ability of the shock absorbing block 4 to absorb vibrations.

[0026] Working principle: When in use, the cutting blade 3 performs turning processing on the rotating workpiece. The length of the part that extends out of the tool as a whole is relatively long. At the same time, the thickness of the cutter head 2 is thin, resulting in a low strength of the cutter head 2, which cannot suppress the vibration generated by the cutting blade during processing. Therefore, a shock-absorbing device is arranged on the cutter head 2. When the rotating workpiece is turned, the vibration is transmitted to the shock-absorbing block 4, and the shock-absorbing block 4 is squeezed by the first mounting member 14 to squeeze the first shock-absorbing member 7, the second shock-absorbing member 8 and the third shock-absorbing member 11, so that the first shock-absorbing member 7, the second shock-absorbing member 8 and the third shock-absorbing member 11 have a certain elastic deformation. When vibration occurs, the shock-absorbing block 4 squeezes the first shock-absorbing member 7, the second shock-absorbing member 8 and the third shock-absorbing member 11, thereby converting the kinetic energy of the vibration into the internal energy of the first shock-absorbing member 7, the second shock-absorbing member 8 and the third shock-absorbing member 11, and finally converting it into heat energy and dissipating it, thereby achieving the shock-absorbing effect of the cutter head 2, ensuring the overall stability of the tool during processing, improving the processing quality, ensuring the qualified rate of the workpiece, avoiding scrap, and saving costs.
