Abstract

The utility model relates to a drive and gear device of a wire cutting and stripping machine and comprises an universal driving shaft, a cutter head gear shaft and an elastic plastic cement key; three or more frenula are arranged on the sides of each cutter head gear shaft and universal driving shaft; the cutter head gear shaft is connected with the universal driving shaft through the elastic plastic cement key; a plastic cement key groove in the elastic plastic cement key is sleeved on the frenula of the universal driving shaft; the cutter head gear shaft is inserted into the plastic cement key groove on the elastic plastic cement key. The utility model has the advantages that the frenula respectively on the universal driving shaft and the cutter head gear shaft are connected with the elastic plastic cement key instead of a splined connection of the original device, so as to avoid the voice produced by a splined metal contact part of the original device and the device becomes more wearable; if the concentricity of the connection of the cutter head gear shaft and the universal driving shaft is error, then the concentricity can be corrected by the elastic plastic cement key; the cutter head gear shaft is designed and processed integrally by adopting the unique process, so as to reduce the quantity of parts and promote the concentricity, drive precision and the precision of the cutting and stripping machine of the whole device.

Description

A kind of wire stripper is cut the transmission and the geared system of stripping device

Technical field

The utility model relates to a kind of transmission and geared system, and particularly a kind of computer wire stripper is cut the transmission and the geared system of stripping device.

Background technology

As shown in Figure 1, the two ends of cutting broach head geared system sprocket drive spindle 2 of prior art wire stripper are fixing with axle sleeve 1, and gear shaft 2 is connected with pitman shaft 4 by spline 3 then, thereby realize transmission.Because adopt many connections, She Ji shortcoming is like this: the concentricity of whole transmission joint is difficult to precisely, and two parts interlocks of spline are difficult to precisely, and noise is big, and wearing and tearing easily.

The utility model content

The purpose of this utility model provides transmission and the geared system that a kind of wire stripper is cut the stripping device, overcomes not accurate, the noise shortcoming big and easy to wear of concentricity of existing computer wire stripper transmission and geared system.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of wire stripper is cut the transmission and the geared system of stripping device, comprise universal driving shaft, cutter head gear shaft and Elastic plastic-rubber key, the side separately of described cutter head gear shaft and universal driving shaft is provided with three or more joint pin, described cutter head gear shaft is connected by the Elastic plastic-rubber key with universal driving shaft, described Elastic plastic-rubber key is provided with the plastic cement keyway, plastic cement keyway in the described Elastic plastic-rubber key is enclosed within on the joint pin of universal driving shaft, in the plastic cement keyway on the described cutter head gear shaft insertion Elastic plastic-rubber key; Described Elastic plastic-rubber key can adopt plastics, rubber or other made.Guarantee that the joint pin of cutter head gear shaft and the joint pin pressure face of universal driving shaft directly do not contact, also can guarantee that joint pin pressure face does not separately directly contact by alternate manner.

Wire stripper described in the utility model is cut the transmission of stripping device and the beneficial effect of geared system is: be connected the unique construction device of side and the spline that the Elastic plastic-rubber key replaces original device separately with universal driving shaft and cutter head gear shaft, the noise of having avoided original device spline Metal Contact part to be produced makes device not easy to wear; If the concentricity that the cutter head gear shaft is connected with universal driving shaft has error slightly, then can correct concentricity by the Elastic plastic-rubber key; And the virgin metal spline can not be corrected, and the cutter head gear shaft adopts unique technology to carry out integrated design processing, has reduced the quantity of part, thereby has improved the concentricity of whole device, thereby the transmission accuracy that has improved whole device has improved the precision of wire stripper.
