Background

Tubular parts are very common workpieces, particularly parts of shaft parts, and have high requirements on manufacturing precision, and the outer wall and the inner wall of the pipe are ensured to have smooth surfaces, no burrs and no pits. Careful protection is required in the manufacturing and transportation processes. The manufacture of parts generally requires multiple processes, with different processes being performed on different production lines. Thus, the completion of one part may require circulation between multiple production lines. In the prior art, a transfer vehicle is generally adopted for transporting tubular parts, one tubular part directly stacks in the vehicle, and for parts with protruding angles, protruding heads or outer plates, if the parts are directly stacked unstably, a supporting frame needs to be designed to support the tubular parts in a layered mode, and the tubular parts are placed on respective fixing frames.

For example, the shock absorber liquid storage cylinder assembly, which is a component of the wheel part of the automobile, is integrally a tube body, the lower end of the tube body is an opening, the upper end of the tube body is a closed end, and a lower support matched with an automobile spring and a support matched with an automobile chassis are welded on the tube body. And after the first workshop shock absorber liquid storage cylinder assembly is welded and formed, transferring the first workshop shock absorber liquid storage cylinder assembly to a second workshop to spray paint on the surface of the part. The painting makes the appearance more pleasing to the eye on the one hand, protects the outward appearance and reduces to rust on the one hand. And after the painting is finished, the paint needs to be transported to a third workshop.

In the prior art, a phi 12 round steel skip car is used for a shock absorber liquid storage cylinder assembly, the shock absorber liquid storage cylinder is used for being supported as a stress point and hung on the skip car, the skip car is easy to drop materials, and particularly in the process of transferring from a second workshop to a third workshop, a paint layer is arranged on the surface of the shock absorber liquid storage cylinder assembly, and the paint layer is very easy to damage due to pressure and vibration. The defective products generated in the transferring process are regarded as inevitable production loss in the prior art, and the loss only presents an increased situation due to workshop environment and worker operation, so that the production yield is low, the production resources are wasted, and the production cost is increased.

Detailed Description

The utility model will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the utility model.

The parts to be transported by the present invention are tubular with hollow interior, and they may have some sharp or protruding structures on their exterior, stacked together unstably, with risk of mutual contusion. Such as a shock absorber reservoir assembly (tubular member shown in fig. 4), to avoid surface damage during part transportation, the present invention is designed.

Referring to fig. 1 to 5, the tubular part transfer frame provided by the utility model comprises a support frame 1, wherein the bottom of the support frame 1 is provided with a travelling wheel, and the support frame 1 comprises an underframe 1-1, a stand column 1-2 and a cross beam 1-3; the two ends of the central line of the underframe 1-1 are fixedly connected with upright posts 1-2 respectively, a plurality of cross beams 1-3 are fixedly connected between the two upright posts 1-2, a ram 3 is fixedly connected on each layer of cross beam 1-3, the inner end of the ram 3 is welded with the cross beam 1-3 into a whole, the outer end extends to the side edge of the cross beam 1-3 and inclines upwards, and the outer end is provided with an elastic cap 4 with a large friction coefficient; the outer end of the ram 3 extends into the tube body of the tubular part 6.

The ram 3 is made of a steel pipe which is properly selected according to the caliber of the lower end of the liquid storage cylinder assembly of the shock absorber. The diameter of the ram 3 should be smaller than the diameter of the tubular part 6. The diameter of the cap 4 is preferably larger than that of the ram 3, and the tubular part 6 and the ram are arranged at an included angle due to the diameter difference between the ram 3 and the cap 4. The upper end of the pipe wall of the tubular part 6 is contacted with the cap 4, and then the lower end of the pipe wall is in point contact with the ram 3 in an inclined state, so that the contact surface between the inner wall of the pipe and the ram 3 is reduced, and the friction damage is reduced. The diameter of the ram 3 can be one third of the pipe diameter of the tubular part 6; the cap 4 is sized to fit the tubular member 6.

If the pipe fitting is provided with openings at two ends, the diameter of the cover cap 4 is matched with that of the tubular part 6, the tubular part 6 is clamped through the friction force of the elastic part, the gravity of the tubular part 6 is prevented from moving downwards, and large vibration can be generated. If the diameter of the cap 4 of the tubular part (such as a liquid storage cylinder assembly of the shock absorber) with the closed upper end is set to be 5mm to 10mm smaller than the pipe orifice of the tubular part 6, the tubular part can be conveniently placed. The cap 4 is a structure convenient for disassembly and assembly, and preferably: as shown in fig. 3, the cap 4 includes a sleeve wrapped on the outer surface of the ram 3, the diameter of the upper closed end of the sleeve is larger than that of the ram 3, and the ram 3 is tightly fitted at the lower open end of the sleeve.
