Embodiment Construction

[0024] The automatic material pulling device of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments of the specification:

[0025] Such as Figure 1~4 As shown, an automatic pulling device includes a cylindrical puller 1 and a cylindrical elastic polyurethane rod 2. One end of the puller 1 forms an inner hole 6, and the elastic polyurethane rod 2 is placed in the inner hole 6. The puller 1 The tail 3 is connected to the knife seat 9, and the outer circle 5 of the inner hole 6 forms a plurality of uniformly distributed long grooves 4 along the circumference.

[0026] The outer diameter of the elastic polyurethane rod 2 matches the inner diameter of the inner hole 6 .

[0027] The long groove 4 is tapered, and the width of the side close to the tail 3 is greater than the width of the side close to the open end of the inner hole 6 .

[0028] The outer circle 5 is in interference fit with the inner hole of the wor...

Abstract

The invention discloses an automatic pulling device. The device comprises a cylindrical puller and a cylindrical elastic polyurethane bar, wherein an inner hole is formed in one end of the puller, the elastic polyurethane bar is arranged in the inner hole, the tail of the puller is connected with a tool apron, and multiple long slots are evenly formed in the outer circle of the inner hole. The device is simple in structure and convenient to use. By means of the elastic releasing structure of the puller and the elastic character of the elastic polyurethane bar, the outer circle of the pulling device is in interference fit with an inner hole of a workblank, in this way, the workblank can be driven to move under the condition that a spindle chuck is open, so that automatic pulling is achieved, machining efficiency is improved greatly, and requirements for bulk production are met.

Description

technical field [0001] The invention belongs to a puller, in particular to an automatic puller. Background technique [0002] In industrialized mass production, when a large number of blanks are continuously processed on a CNC lathe, it is often necessary to manually pull out a certain length of the blank after processing a part, and then clamp the spindle chuck before proceeding. Machining of the next part. However, the process of manual material extraction wastes a lot of processing time and affects processing efficiency. At present, in mass production, the more advanced technology is to add an automatic feeder to the CNC lathe to complete the automatic feeding process, but the cost of the automatic feeder is high, the precision of the blank is high, and it needs to occupy a large amount of production space. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings in the prior art, and its purpose is to provide an autom...
