Description

Technical Field

[0001] The invention relates to the technical field of V-type thrust rod processing tooling, in particular to a V-type thrust rod press-fitting tooling for a heavy truck. Background Art

[0002] The V-type thrust rod press-fitting tool is an important equipment used in the assembly process of automobile thrust rods. It is mainly used to accurately press and assemble the ball head and sleeve assembly of the V-type thrust rod.

[0003] In the prior art, the V-type thrust rod press-fitting tooling is only provided with a main press seat. When the large end of the V-type thrust rod is press-fitted, the large end of the V-type thrust rod is placed on the main press seat, and then a press is used for press-fitting. After the large end is press-fitted, the small end is placed on the main press seat for press-fitting. No matter which end is press-fitted, the other end will be in an unstable state. During press-fitting, the operator needs to support it. Although it can ensure the stability of the V-type thrust rod, it cannot ensure that the force on the pressed end is balanced, which leads to poor press-fitting effect. During press-fitting, the operator's manual support greatly increases the operation risk. For this reason, we have designed a heavy truck V-type thrust rod press-fitting tooling to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to propose a heavy truck V-type thrust rod press-fitting tool.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

When the V-shaped thrust rod is press-fitted, a vertical assembly relationship of the V-shaped thrust rod is realized, so that the force-bearing surface is perpendicular to the force-applying surface, thereby effectively ensuring the assembly quality and reducing damage to the spherical pin assembly caused by oblique press-fitting.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-3 A heavy truck V-type thrust rod press-fitting tool comprises a bottom plate 1, a support plate 2 and a V-type thrust rod body 12. The front and rear side walls of the bottom plate 1 are provided with a plurality of small notches 9. The setting of the small notches 9 on the bottom plate 1 can be connected and locked with T-bolts according to the work surface, which is convenient for installation. The connection between the bottom plate 1 and the support plate 2 is fixedly connected by a plurality of reinforcing ribs 7. The side walls of the connection ends of the bottom plate 1 and the support plate 2 are provided with large notches 8. The setting of the large notches 8 eliminates the front and rear interference when the V-type thrust rod body 12 is press-fitted. A plurality of support blocks 6 are fixedly installed at the bending part of the support plate 2. A main press seat 3 and a mounting block 10 are fixedly installed on the top of the bottom plate 1. The design of the main press seat 3 combines the existing Specifications of press-fitting, taking into account the small end The size of the center opening of the main pressure seat 3 takes into account the press-fitting of the four-hole spherical pin assembly and the two-hole spherical pin assembly. The main pressure seat 3 is fixedly installed on the base plate 1 by a plurality of bolts. The bolt connection between the base plate 1 and the main pressure seat 3 realizes the replaceability of the main pressure seat 3 after the precision fails due to wear. A slide groove 14 is provided on the top of the mounting block 10. A clamping mechanism and a driving mechanism are provided in the slide groove 14. The inner wall of the clamping mechanism is against the side wall of the V-type thrust rod body 12. The clamping mechanism includes two sliders 16 slidably connected in the slide groove 14. Threaded holes 17 are provided through the two sliders 16. Clamps 13 are fixedly installed on the tops of the two sliders 16. Rubber pads 18 are fixedly installed on the side walls of the two clamps 13. The side walls of the rubber pads 18 are provided with anti-slip grooves. The side walls of the two rubber pads 18 are against the side walls of the V-type thrust rod body 12.

[0026] The driving mechanism passes through the clamping mechanism and is threadedly connected thereto. A large-end support 4 and a small-end support 5 are fixedly installed on the top of the support plate 2. The tops of the large-end support 4 and the small-end support 5 are both inclined. Through the arrangement of the large-end support 4 and the small-end support 5, the functions of pressing the large-end of the V-shaped thrust rod to the small-end support and the small-end to the large-end support are well completed. Through the arrangement of the main pressure seat 3, the large-end support 4 and the small-end support 5, when the V-shaped thrust rod body 12 is press-fitted, a vertical assembly relationship of the V-shaped thrust rod body 12 is realized, so that the force-bearing surface is perpendicular to the force-applying surface, effectively ensuring the assembly quality and reducing the damage to the spherical pin assembly caused by the oblique press-fitting. The V-shaped thrust rod body 12 is placed between the main pressure seat 3 and the top of the small end support 5. The driving mechanism includes a double-headed screw 15 rotatably connected to the inner wall of the slide groove 14. The double-headed screw 15 passes through two threaded holes 17 and is threadedly connected thereto. The double-headed screw 15 passes through the side wall of the mounting block 10 and is rotatably connected thereto. A screw cap 11 is fixedly installed on the end of the double-headed screw 15. Through the arrangement of the mounting block 10, the slide groove 14, the driving mechanism and the clamping mechanism, when the V-shaped thrust rod body 12 is press-fitted, the V-shaped thrust rod body 12 can be limited and clamped to keep it stable, thereby avoiding displacement caused by force during press-fitting.

[0027] The present invention can be explained by the following operation mode:

[0028] When the spherical pin assembly needs to be press-fitted on the V-type thrust rod body 12, first, the operator places the large end of the V-type thrust rod body 12 on the top of the main pressure seat 3, at which time one of the small ends on the V-type thrust rod body 12 abuts against the top of the small end support 5, and the small end support 5 supports the small end of the V-type thrust rod body 12, so that the large end surface of the V-type thrust rod body 12 is horizontally placed on the main pressure seat 3, and the screw cap 11 is turned, and the screw cap 11 drives the double-headed screw 15 to rotate. When the double-headed screw 15 rotates, it drives the clamping plate 13 on the slider 16 to move, so that the side walls of the rubber pads 18 on the two clamping plates 13 abut the two rod body surfaces on the V-type thrust rod body 12, so that the V-type thrust rod body 12 is limited and fixed, and then the spherical pin assembly is press-fitted into the large end of the V-type thrust rod body 12 using a press;

[0029] After the big end of the V-shaped thrust rod body 12 is press-fitted, the operator rotates the screw cap 11 in the opposite direction so that the two rubber pads 18 are separated from the tight contact with the V-shaped thrust rod body 12, and then flips the V-shaped thrust rod body 12 so that one small end of the V-shaped thrust rod body 12 is placed on the top of the main pressure seat 3. At this time, the big end of the V-shaped thrust rod body 12 is against the top of the big end support 4, and then the screw cap 11 is rotated again so that the rubber pads 18 on the two clamping plates 13 abut the rod surface of one end of the V-shaped thrust rod body 12, and then a press is used for press-fitting. After the small end of one end of the V-shaped thrust rod body 12 is press-fitted, the V-shaped thrust rod body 12 is flipped over by the above method so that the other small end of the V-shaped thrust rod body 12 is placed on the main pressure seat 3, and then it is press-fitted.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
