Abstract

The utility model discloses a fixed frock structure of transmission shaft slip pair, it is vice mainly including the transmission shaft slip, the transmission shaft slip pair mainly includes the universal joint, the external spline axle, staple bolt A, rubber bellows, staple bolt B and internal spline axle, the one end cartridge of external spline axle is sliding fit in the internal spline axle, the universal joint is installed to the other end of external spline axle, the rubber bellows both ends are fixed on external spline axle and internal spline axle and shelter from the junction of external spline axle and internal spline axle through staple bolt A and staple bolt B suit respectively, fixed frock sets up in the rubber bellows outside. The utility model uses a brand new simple tool, innovatively utilizes the holding position fixation of the hoop, not only can meet the fixation requirement of the sliding pair, but also avoids paint repair after the oven comes out, does not influence paint spraying, and ensures that the paint quality of each part of the product is stable and consistent; the original mode of firstly binding iron wires and then patching paint is completely replaced, and the defect of the iron wire binding mode is overcome.

Description

Fixing tool structure for sliding pair of transmission shaft

Technical Field

The utility model relates to a field of transmission shaft, concretely relates to vice fixed frock structure of transmission shaft slip.

Background

After the transmission shaft with the sliding pair is assembled, the transmission shaft is required to be vertically suspended and subjected to a paint baking process, the structure is shown in figure 1, the universal joint 1, the outer spline shaft 2, the hoop A3, the rubber corrugated pipe 4, the hoop B5, the inner spline shaft 6, the binding iron wire 7 and the welding line 8 are mainly included, and in order to prevent the rubber corrugated pipe 4 on the outer side of the sliding pair from deforming after being baked at high temperature (the rubber corrugated pipe 4 can be elongated after being baked at high temperature and cannot be retracted after being cooled), the binding iron wire 7 is required to be used for binding and then enters a paint baking oven. In order to avoid hurting the rubber corrugated pipe 4 when binding the binding iron wires 7, the binding iron wires 7 are bound at the universal joint 1 and the welding seam 8, the binding iron wires 7 are cut off after coming out of the paint oven, paint is replenished on binding positions, and the paint replenishing quality is poor and time consuming due to labor consumption.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a transmission shaft slides vice fixed frock structure.

The purpose of the utility model is accomplished through following technical scheme: this kind of fixed frock structure of transmission shaft sliding pair, it is main including the transmission shaft sliding pair, the transmission shaft sliding pair mainly includes the universal joint, the external spline shaft, staple bolt A, rubber bellows, staple bolt B and internal spline shaft, the one end cartridge of external spline shaft is sliding fit in the internal spline shaft, the universal joint is installed to the other end of external spline shaft, the rubber bellows both ends are fixed on external spline shaft and internal spline shaft and shelter from the junction of external spline shaft and internal spline shaft through staple bolt A and staple bolt B suit respectively, fixed frock sets up in the rubber bellows outside, the tip at fixed frock both ends colludes the rigidity of holding staple bolt A and staple bolt B tightly on staple bolt A3 and staple bolt B respectively.

Fixed frock mainly includes the reinforcing bar, and the reinforcing bar both ends are bent and are formed U type structure, and the reinforcing bar both ends set up the tip and collude, and two tips collude and all towards the U type inboard.

The utility model has the advantages that: the utility model uses a brand new fixing tool, innovatively utilizes the holding position of the hoop to fix, not only can meet the fixing requirement of the sliding pair, but also avoids paint repair after the oven comes out, does not influence paint spraying, and ensures that the paint quality of each part of the product is stable and consistent; the original mode of firstly binding iron wires and then patching paint is completely replaced, and the defect of the iron wire binding mode is overcome.

Fig. 2 is a schematic structural diagram of the present invention.

Fig. 3 is a schematic view of the simple tool of the present invention.

Description of reference numerals: the universal joint comprises a universal joint 1, an external spline shaft 2, a hoop A3, a rubber corrugated pipe 4, a hoop B5, an internal spline shaft 6, a bound iron wire 7, a welding seam 8, a fixing tool 9, a pointed hook 10 and a reinforcing steel bar 11.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in the attached drawings, the fixing tool structure of the transmission shaft sliding pair mainly comprises the transmission shaft sliding pair, the transmission shaft sliding pair mainly comprises a universal joint 1, an outer spline shaft 2, a hoop A3, a rubber corrugated pipe 4, a hoop B5 and an inner spline shaft 6, and the transmission shaft is vertically suspended on a paint production line. The one end cartridge of external spline shaft 2 is sliding fit in internal spline shaft 6, universal joint 1 is installed to external spline shaft 2's the other end, 4 both ends of rubber bellows are fixed on external spline shaft 2 and internal spline shaft 6 and shelter from the junction of external spline shaft 2 and internal spline shaft 6 through staple bolt A3 and staple bolt B5 suit respectively, fixed frock 9 sets up in the rubber bellows 4 outside, the tip that fixed frock 9 both ends colludes 10 colludes on staple bolt A3 and staple bolt B5 respectively with the position that staple bolt A3 and staple bolt B5 hold tightly fixed. Fixed frock 9 mainly includes that the diameter is 4 mm's reinforcing

bar

11, and 11 both ends of reinforcing bar are bent and are formed U type structure, and the reinforcing bar both ends set up the tip and collude 10, and two tips collude 10 and all towards the U type inboard.

During the use, the tip that fixed frock 9 upper end colludes 10 and puts the position of embracing tightly on staple bolt A3, lifts the sliding pair upwards slightly with the hand, puts the tip that fixes frock 9 lower extreme and colludes 10 and embrace the position on staple bolt B5, loosens the sliding pair, because of the action of gravity, both ends tip colludes 10 and eats two staple bolts A3 and staple bolt B5 tightly. The position that uses fixed frock 9 to hold staple bolt A3 and staple bolt B5 tightly is fixed for there is not the problem of elongation deformation in rubber bellows 4, can satisfy the vice fixed requirement of sliding, avoids again needing the touch-up paint (not influencing the spraying paint) after the oven comes out.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
