Description

Technical Field

[0001] This utility model relates to the field of intermediate shaft processing technology, specifically to an intermediate shaft floating clamping fixture. Background Technology

[0002] During the assembly of the universal joint bearing on the intermediate shaft, the parts may move under stress, which can easily lead to poor bearing press-fitting. Additionally, the height difference between the lugs on both sides of the joint fork can cause the rivet points on both sides to be of different sizes.

[0003] To prevent the above problems, tooling is needed to clamp the parts. However, tooling with a simple rigid connection is prone to generating a large impact force when driven by the cylinder, which can damage the parts. At the same time, it cannot calibrate the difference in rivet size caused by the different heights of the ear holes.

[0004] Therefore, it is necessary to design a floating clamping fixture for the intermediate shaft to reduce the damage to the parts caused by the clamping fixture, and at the same time, to solve the problem of rivet size caused by the different heights of the fork lugs. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a floating clamping fixture for intermediate shafts to reduce the damage to parts caused by the clamping of the fixture, while solving the problem of rivet size caused by the different heights of the fork lugs.

[0006] To achieve the above objectives, this utility model provides a floating clamping fixture for an intermediate shaft, comprising a positioning connecting rod, a spring, a threaded joint, a threaded guide sleeve, a guide rod, a ball groove joint, and a spherical cap. The upper end of the threaded joint is inserted into the inner hole of the positioning connecting rod, and the lower end of the threaded joint is threadedly connected to the threaded guide sleeve. The spring is located inside the threaded guide sleeve, with one end of the spring inserted into the lower inner hole of the threaded joint, and the other end of the spring sleeved around the guide post at the top of the guide rod. The upper end of the guide rod is slidably mounted inside the threaded guide sleeve. The connecting post of the ball groove joint is inserted into the inner hole of the guide rod. The spherical cap is rotatably mounted at the bottom of the ball groove joint, and the end of the tube is inserted into the bottom of the spherical cap.

[0007] The threaded joint and the positioning connecting rod, and the ball groove joint and the guide rod are fixed with set screws.

[0008] The threaded guide sleeve is fixed to the positioning connecting rod.

[0009] The threaded guide sleeve and the positioning connecting rod are fixed by a tenon and mortise structure.

[0010] Compared with the prior art, this utility model enables the shaft and tube parts to float and be pressed together during the assembly of the intermediate shaft universal joint bearing. This can reduce the impact damage to the parts caused by the tooling clamping, and can also realize the self-alignment of the center of the joint fork lug hole, solving the problem of rivet point size differences caused by the uneven height of the joint fork lugs.

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] See Figure 1 , Figures 3-8 This utility model discloses a floating clamping fixture for an intermediate shaft, comprising a positioning connecting rod, a spring, a threaded joint, a threaded guide sleeve, a guide rod, a ball groove joint, and a spherical pressure cap. The upper end of the threaded joint 3 is inserted into the inner hole of the positioning connecting rod 1, and the lower end of the threaded joint 3 is threadedly connected to the threaded guide sleeve 4. The spring 2 is located inside the threaded guide sleeve 4, and one end of the spring 2 is inserted into the lower end inner hole of the threaded joint 3. The other end of the spring 2 is sleeved on the guide post 51 at the top of the guide rod 5. The upper end of the guide rod 5 is slidably installed inside the threaded guide sleeve 4. The connecting post 61 of the ball groove joint 6 is inserted into the inner hole of the guide rod 5. The spherical pressure cap 7 is rotatably installed at the bottom of the ball groove joint 6, and the end of the tube 8 is inserted into the bottom of the spherical pressure cap 7.

[0021] The threaded connector 3 and the positioning connecting rod 1, and the ball groove connector 6 and the guide rod 5 are fixed with set screws.

[0022] To prevent the threads of the threaded connector 3 and the threaded guide sleeve 4 from loosening due to repeated pressing, the guide sleeve 4 is fixed to the positioning connecting rod 1. Preferably, the threaded guide sleeve 4 and the positioning connecting rod 1 are fixed using a tenon and mortise structure.

[0023] When this invention comes into contact with a part, the downward impact force compresses the spring 2, causing it to deform. This buffers the large downward impact force, reducing damage to the part. Figure 2 As shown, the spherical cap 7 and the ball groove joint 6 adopt the working principle of thrust spherical sliding bearing. The spherical cap 7 adjusts its angle according to the height difference of the end face of the parts to ensure that the height of the contact lug at the end of the tube 8 is consistent and that the size of the rivet is uniform.

[0024] This invention has been tested on the production line and shows significant results.

[0025] This invention enables the floating clamping of shaft and tube parts during the assembly of the intermediate shaft universal joint bearing, which can reduce the impact damage to the parts caused by tooling clamping. It can also realize the self-alignment of the center of the joint fork lug hole, and solve the problem of rivet point size difference caused by the different height of the joint fork lugs.
