Description

Numerical control milling shock absorber for thin-wall parts

Technical Field

The utility model relates to a numerical control milling process technical field, concretely relates to thin wall part numerical control milling process bumper shock absorber.

Background

In the process of numerical control milling processing of thin-wall parts, direct milling processing is used in the past, a thin-wall workpiece is directly processed, only structural strength of the workpiece can be utilized for supporting, processing quality is low, vibration lines on the processed surface are obvious due to vibration cutter relieving of the thin-wall part, and surface smoothness and roughness are seriously affected.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a thin wall part numerical control mills processing bumper shock absorber has solved current thin wall work piece processing and has leaded to processingquality low, and the problem of workpiece surface finish degree and roughness is obviously influenced to the processing surface chatter marks.

The technical scheme is as follows: the utility model discloses thin wall part numerical control mills processing bumper shock absorber, including first grip block and second grip block, first grip block is located the top of second grip block, and the top of first grip block is equipped with the first recess the same with first grip block width, the center department of first recess is equipped with first through-hole, the bottom of second grip block is equipped with the second recess the same with second grip block width, the center department of second recess is equipped with the second through-hole, be equipped with the bolt in the first through-hole, the other end of bolt pass the second through-hole and with nut threaded connection.

Furthermore, the right side face of the first clamping block is an inclined face, and a layer of rubber pad is arranged on the inclined face. The rubber pad can support and reduce thin-wall vibration generated in processing.

Furthermore, a cushion pad is arranged on the left side between the first clamping block and the second clamping block. The stability of bumper pad assurance shock absorber in the course of working.

Furthermore, a spring is further arranged between the first clamping block and the second clamping block, and the spring is sleeved on a screw rod of the bolt.

Furthermore, a first groove on the first clamping block corresponds to a second groove on the second clamping block, and a first through hole at the center of the first groove corresponds to a second through hole at the center of the second groove.

Has the advantages that: the utility model discloses a bumper shock absorber adds in the processing of thin wall work piece, very big reduction the thin wall vibration, processingquality promotes greatly, and smooth finish and roughness reach normal solid work piece standard basically.

Detailed Description

The invention will be further described with reference to the following figures and examples:

as shown in fig. 1 to 3, the utility model discloses thin wall part numerical control milling bumper shock absorber, including first grip block 1 and second grip block 2, first grip block 1 is located the top of second grip block 2, the top of first grip block 1 is equipped with the first recess 3 the same with first grip block 1 width, the center department of first recess 3 is equipped with first through-hole 4, the bottom of second grip block 2 is equipped with the second recess 5 the same with second grip block 2 width, the center department of second recess 5 is equipped with second through-hole 6, the first recess 3 position on first grip block 1 corresponds with the second recess 5 position of 2 on the second grip block, the first through-hole 4 position of first recess 3 center department corresponds with the second through-hole 6 position of second recess 5 center department;

a bolt 7 is arranged in the first through hole 4, the other end of the bolt 7 penetrates through the second through hole 6 and is in threaded connection with the nut, a spring 8 is further arranged between the first clamping block 1 and the second clamping block 2, and the spring 8 is sleeved on a screw rod of the bolt 7 and used for ensuring the stability of the shock absorber during processing;

meanwhile, the right side surface of the first clamping block 1 is an inclined surface, a layer of rubber pad 9 is arranged on the inclined surface, and the rubber pad 9 can support and reduce thin-wall vibration generated in machining; a buffer pad 10 is arranged on the left side between the first clamping block 1 and the second clamping block 2, and the buffer pad 10 can also ensure the stability of the shock absorber in the machining process.

The working principle is as follows:

1. clamping a thin-wall workpiece 11 through a first clamping block 1 and a second clamping block 2;

2. the bolt 7 penetrates through the first through hole 4 and the second through hole 6 of the bolt to be adjusted and fastened, so that the shock absorber is prevented from falling off in the machining process; meanwhile, a screw of the bolt 7 is sleeved with a spring 8, and a cushion pad 10 is arranged on the left side between the first clamping block 1 and the second clamping block 2, so that the spring 8 and the cushion pad 10 can ensure the stability of the shock absorber in the processing process and are not easy to fall off;

3. the gap is adjusted by the inclined surface on the first clamping block 1, the first clamping block is attached to the back surface of the processing surface of the thin-wall workpiece 11, and the rubber pad 9 is used for supporting and reducing thin-wall vibration generated in the processing.

The utility model discloses a bumper shock absorber adds in the processing of thin wall work piece 11, very big reduction the thin wall vibration, and processingquality promotes greatly, and smooth finish and roughness reach normal solid work piece standard basically.
