Embodiment 1

[0045] Such as figure 1 As shown, a damping shock absorber includes:

[0046] Adjustment lever 6;

[0047] A mass block 3, the mass block 3 is sheathed on the outside of the adjustment rod 6 through clearance fit;

[0048] A support block assembly 2, the two ends of the support block assembly 2 and the adjustment rod 6 are respectively connected by threaded fit;

[0049] The elastic body assembly 1 is sleeved on the outside of the adjustment rod 6 and placed between the mass block 3 and the support block assembly 2 .

[0050] The support block assembly 2, the elastic body assembly 1, and the mass block 3 are sealed and connected, and the gap between the mass block 3 and the adjustment rod 6 is filled with damping oil.

[0051] In this embodiment, the molded casing is stepped-fitted between the support block assembly and the elastic body assembly, thereby achieving greater shock absorption effects in both the axial and radial directions of the tool holder.

[0052] further,...

Embodiment 2

[0062] Such as Figure 7 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between this embodiment two and embodiment one is:

[0063] This embodiment also discloses a damping and damping tool holder, which includes a tool holder body 9 and a damping and vibration absorber described in Embodiment 1, which is built into the body of the cutter holder 9 Inside, the inner wall of the cutter bar body 9 is provided with a cylindrical hole a91, a conical hole 92, a cylindrical hole b93 and a cylindrical hole c94 in sequence along its axial direction from front to back, and the cylindrical hole a91 is connected to the front end support block 4 It cooperates with the front elastic body 7 , the conical hole 92 cooperates with the mass block 3 , and th...

Embodiment 3

[0069] Such as Figure 8 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between this embodiment three and embodiment one is:

[0070] This embodiment also discloses a damping and vibration-damping cutter, including a cutter head 10 and a damping and vibration-damping cutter bar described in Embodiment 2. The cutter head 10 is installed on the front end support block 4, It is fixed with the hollow structure front end of cutter bar body 9 simultaneously.

[0071] In this embodiment, the cutter head 10 is installed on the cutter bar of the second embodiment, and the vibration of the cutter head 10 is weakened during actual use, so as to improve the accuracy of the cutter work.

Abstract

The invention provides a damping shock absorber which comprises an adjusting lever, a mass block, supporting block components and elastomer components, wherein the mass block is arranged outside the adjusting lever in a sleeving manner in a clearance fit manner; the supporting block components are arranged at the two ends of the adjusting lever; the elastomer components are arranged outside the adjusting lever in a sleeving manner and are arranged between the mass block and the corresponding supporting block components; the supporting block components, the elastomer components and the mass block are hermetically connected; and a gap between the mass block and the adjusting lever is filled with damping oil. The invention also provides a toobar and a tool with the damping shock absorber applied. According to the damping shock absorber, the toolbar and the tool, the vibration of the long overhanging tool in cutting is greatly reduced, efficient and stable cutting is realized, the requirements on the processing precision and the roughness of a product are met, the advantages of high stability and high precision are achieved, and particularly the tool is suitable for cutting metal underthe working condition of long overhanging processing.

Description

technical field [0001] The invention relates to the technical field of cutting, in particular to a damping shock absorber and a cutter bar and a tool using the damping shock absorber. Boring cutting, etc.) for metal cutting. Background technique [0002] Due to the special functions of deep-processed parts, deep-processed parts often become the key components that determine product quality and efficiency. Due to the uniqueness of large length-to-diameter ratio and multiple interference constraints, deep processing has inherent disadvantages such as poor rigidity system, difficult cooling, and obvious vibration. In addition, the rotation and feeding of the tool in deep processing are accompanied by the pressure of high-pressure cutting fluid. Dynamic load coupling, which leads to frequent bending and torsional vibrations in deep processing, and aggravates the wear of deep processing tools. These working conditions require a long overhang for the tool. At this time, due to i...
