Abstract

The invention discloses a fixing tool structure of a transmission shaft sliding pair, which mainly comprises a transmission shaft sliding pair, wherein the transmission shaft sliding pair mainly comprises a universal joint, an external spline shaft, a hoop A, a rubber bellows, a hoop B and an internal spline shaft, one end of the external spline shaft is inserted into the internal spline shaft in a sliding fit manner, the other end of the external spline shaft is provided with the universal joint, two ends of the rubber bellows are respectively sleeved and fixed on the external spline shaft and the internal spline shaft through the hoop A and the hoop B and shield the joint of the external spline shaft and the internal spline shaft, a fixing tool is arranged outside the rubber bellows, and pointed hooks at two ends of the fixing tool are respectively hooked on the hoop A3 and the hoop B to fix the clasping positions of the hoop A and the hoop B. According to the novel simple tool, the clamping position of the hoop is innovatively utilized to fix, so that the fixing requirement of the sliding pair can be met, the need of paint supplementing after the baking oven comes out is avoided, paint spraying is not affected, and the quality of paint at all positions of a product is stable and consistent; the method completely replaces the original mode of firstly binding iron wires and then repairing paint, and avoids the defects of the iron wire binding mode.

Description

Fixing tool structure for sliding pair of transmission shaft

Technical Field

The invention relates to the field of transmission shafts, in particular to a fixing tool structure of a transmission shaft sliding pair.

Background

After the assembly of the transmission shaft with the sliding pair is completed, the transmission shaft with the sliding pair is required to be vertically hung and subjected to a varnish baking process, and the structure is shown in fig. 1, and mainly 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, binding iron wires 7 and a welding seam 8, wherein in order to avoid deformation of the rubber corrugated pipe 4 outside the sliding pair after high-temperature baking (the rubber corrugated pipe 4 is lengthened after high-temperature baking and is not retracted after cooling), the rubber corrugated pipe is bound by the binding iron wires 7 and then enters a varnish baking oven. In order to avoid the rubber bellows 4 from being hurt by the reining force when the binding iron wires 7 are bound, the binding iron wires 7 are bound at the universal joint 1 and the welding seam 8, the binding iron wires 7 are sheared after the binding iron wires 7 come out of the paint oven, and then paint is filled in the binding position, so that the paint filling quality is poor and the labor and time are consumed.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides a fixture structure for fixing a sliding pair of a transmission shaft.

The invention aims at being completed by the following technical scheme: this kind of fixed frock structure of transmission shaft sliding pair mainly includes transmission shaft sliding pair, transmission shaft sliding pair mainly includes the universal joint, 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 internal spline shaft, the universal joint is installed to the other end of external spline shaft, rubber bellows both ends are fixed on external spline shaft and internal spline shaft respectively through staple bolt A and staple bolt B suit and shelter from external spline shaft and internal spline shaft's junction, fixed frock sets up in the rubber bellows outside, the tip at fixed frock both ends is colluded respectively and is held the position fixing that hugs staple bolt A and staple bolt B on staple bolt A3 and staple bolt B.

The fixing tool mainly comprises a steel bar, two ends of the steel bar are bent to form a U-shaped structure, two ends of the steel bar are provided with pointed hooks, and the two pointed hooks face towards the inner side of the U-shaped structure.

The beneficial effects of the invention are as follows: according to the novel fixing tool, the clamping position of the hoop is innovatively used for fixing, so that the fixing requirement of the sliding pair can be met, the need of paint supplementing after the baking oven comes out is avoided, paint spraying is not affected, and the quality of paint at all positions of a product is stable and consistent; the method completely replaces the original mode of firstly binding iron wires and then repairing paint, and avoids the defects of the iron wire binding mode.

Detailed Description

The invention will be described in detail below with reference to the attached drawings:

examples: as shown in the attached drawing, the fixing tool structure of the transmission shaft sliding pair mainly comprises a transmission shaft sliding pair, wherein the transmission shaft sliding pair mainly comprises a universal joint 1, an external spline shaft 2, a hoop A3, a rubber corrugated pipe 4, a hoop B5 and an internal spline shaft 6, and the transmission shaft is vertically hung on a paint assembly line. One end cartridge of external spline shaft 2 is sliding fit in internal spline shaft 6, universal joint 1 is installed to the other end of external spline shaft 2, and rubber bellows 4 both ends are fixed on external spline shaft 2 and internal spline shaft 6 respectively through staple bolt A3 and staple bolt B5 suit and shelter from external spline shaft 2 and internal spline shaft 6's junction, and fixed frock 9 sets up in rubber bellows 4 outside, and the tip at fixed frock 9 both ends is colluded 10 respectively and is held the position fixing that the staple bolt A3 and staple bolt B5 held tightly on staple bolt A3 and staple bolt B5. The fixing tool 9 mainly comprises a steel bar 11 with the diameter of 4mm, two ends of the steel bar 11 are bent to form a U-shaped structure, two ends of the steel bar are provided with pointed hooks 10, and the two pointed hooks 10 face towards the inner side of the U-shaped structure.

When the clamp is used, the tip hook 10 at the upper end of the fixed tool 9 is placed at the holding position on the anchor ear A3, the sliding pair is slightly lifted upwards by hands, the tip hook 10 at the lower end of the fixed tool 9 is placed at the holding position on the anchor ear B5, the sliding pair is loosened, and due to the action of gravity, the two ends of the tip hook 10 are used for holding the two anchor ears A3 and B5. The fixing tool 9 is used for fixing the holding hoop A3 and the holding hoop B5 in a holding manner, so that the problem of stretching deformation of the rubber corrugated pipe 4 is solved, the fixing requirement of the sliding pair can be met, and the need of paint repair (without affecting paint spraying) after the baking oven comes out is avoided.

It should be understood that equivalents and modifications to the technical scheme and the inventive concept of the present invention should fall within the scope of the claims appended hereto.
