Description

Elastic jacket device with helix angle

Technical Field

The invention relates to an elastic jacket device with a helix angle, belonging to the technical field of machining.

Background

Square teeth, trapezoids, saw teeth, worms and multi-start threads are generally used as transmission parts, so the precision requirement is higher, moreover, because the thread pitches and the lead angles of the square teeth, the trapezoid, the saw teeth, the worms and the multi-start threads are larger, the machining is more difficult, when the threads are turned, the cutting condition of a turning tool is greatly changed due to the influence of spiral motion, and the influence is determined by the lead angle of the threads of a workpiece. When the lead of the thread is the same and the diameter of the thread is larger, the lead angle of the thread is smaller, and due to the influence of the lead angle, the positions of the cutting plane and the base surface are changed, so that the front angle and the rear angle of the turning tool during working are changed. In actual cutting, the existing processing mode is that a cutter body is ground to enable the angle of the cutter body to be the same as the helix angle, then clamping processing is carried out, the cutter is ground by the method, the strength of the cutter is reduced, the cutter after grinding is not suitable for processing other parts, and the universality is poor; the other method is to install a thin pad with an angle when the cutter is clamped, the angle is the same as the helix angle, the processing quality of the part is guaranteed, but the method is complex in clamping, long in clamping time and low in processing efficiency.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides the elastic jacket device with the lead angle, the device enables the angle formed by the square hole and the jacket body to be consistent with the lead angle with the large pitch by arranging the square hole in the jacket body in the lead angle with the large pitch, and the jacket body has certain elasticity by the notch, so that the lead angle threads in different directions can be processed on a part, the processing precision and the processing quality of the part are effectively ensured, the processing efficiency is high, and the processing is carried out in a mode of no need of grinding a cutter or adding a gasket.

The technical scheme adopted by the invention for solving the technical problem is as follows: an elastic jacket device with a lead angle comprises a jacket body, wherein the jacket body is of a cuboid structure, a through-long square hole is formed in the jacket body, the square hole and the jacket body are arranged in a horizontal direction at an alpha angle, the alpha angle of the square hole is the same as the lead angle of a large-pitch screw to be processed, the range of the alpha angle is 37-4 degrees 54', and the size of the square hole is 20 x 20mm; the front and the back of the jacket body are respectively provided with two strip-shaped openings which are parallel at intervals, the openings in the two planes are symmetrically arranged, and the directions of the two openings in the same plane are opposite.

The invention has the beneficial effects that: the invention meets the requirements of product drawings and batch production in the processing process, improves the production efficiency and the processing quality of parts, meets the requirement of part interchangeability, and has strong operability and small manufacturing difficulty; the elastic clamping sleeve device with the helix angle can effectively ensure the processing precision of parts, realize quick clamping and reduce the labor intensity of workers; the processing method of the jacket device can be popularized to clamping processing of square teeth, trapezoids, sawteeth, worms and multi-start threads with various large screw pitches and large tooth depths, plays an important role in ensuring the quality of workpieces and improving the production efficiency, plays an important role in guiding high-precision processing of the threads with the large screw pitches and the large tooth depths, has relatively wide popularization value, and obtains remarkable economic benefits and social benefits.

Detailed Description

As shown in fig. 1 to 3, an elastic jacket device with a lead angle comprises a jacket body 1, wherein the jacket body 1 is of a cuboid structure, a through-long square hole 101 is formed in the jacket body 1, the square hole 101 and the jacket body 1 are arranged in a horizontal direction at an angle α, the angle α of the square hole 101 is the same as the lead angle of a large pitch to be processed, the range of the angle α is 37 "to 4 54" at 2 °, and the size of the square hole 101 is 20 × 20mm; the front and the back of the jacket body 1 are respectively provided with two strip-shaped openings 102 which are parallel at intervals, the orientations of the two openings 102 in the same plane are opposite, the openings 102 in the two planes are symmetrically arranged, the width of the opening 102 is 0.5mm, and the root of the opening 102 is a round hole with the diameter phi 1 mm.

The elastic clamping sleeve device is suitable for common and numerical control cutters with the cutter square of 20mm, the cutters are clamped in the square holes 101 in one side of the clamping sleeve body 1, small gaps exist between the square holes 101 and the cutters, and when the cutters are clamped, the clamping sleeve body 1 has elasticity due to the fact that the side walls of the notches 102 in the two sides abut against the cutters, the cutters can be clamped more effectively through the gaps, and the notches 102 enable the cutters to be clamped more stably without loosening; because the angle alpha of the square hole 101 is consistent with the helix angle of the large pitch, the square hole 101 arranged at the angle alpha can be directly processed and used when the helix angle of the large pitch is processed.

When processing, a cutter is installed in the square hole 101 on one side in the jacket body 1 in a matched mode, the cutter is directly installed in a cutter holder of a machine tool and screwed tightly for processing, if a lead angle thread with threads in opposite rotating directions needs to be processed, the jacket body 1 only needs to be rotated by 180 degrees, and the cutter is installed on the other side of the jacket body 1 for clamping and processing.
