[0002] In the production process of crawler tracks, in order to improve the production efficiency of crawler tracks, high-precision four-axis tightening machines are generally used to tighten the bolts and nuts of crawler tracks. The high-precision four-axis tightening machine can tighten 4 bolts at the same time. Because the positions of the bolts are different for different crawler models, the position of the four-axis tightening machine is fixed by the tooling plate, and each model of crawler tracks uses the corresponding tooling plate.

[0031] 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 of the embodiments.

[0032] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0033] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a combined four-axis tightening machine tooling plate is provided, which is installed on the frame of the four-axis tightening machine and is used to limit the installation of four tightening shafts on the four-axis tightening machine. It mainly includes a base plate seat 100, four limit guide sleeves 200 and a plurality of locking bolts 300. By setting the limit guide sleeve 200, the service life of the base plate seat 100 can be significantly increased. When abnormal replacement is required, only the limit guide sleeve 200 needs to be replaced, and the base plate seat 100 does not need to be replaced, which is fast and convenient.

[0034] Specifically, the main core solution of the tooling plate is to install the limiting guide sleeves 200 on the original base plate seat 100 respectively. The limiting guide sleeves 200 all adopt an annular T-shaped structure and have a hollow inner cavity with a certain diameter for passing the tightening shaft.

[0035] Each of the limiting guide sleeves 200 is respectively embedded in the positioning holes 101 at corresponding positions on the base plate seat 100, serving as a transition connection component between the tightening shaft and the base plate seat 100, so as to form a new positioning channel for limiting the installation of the tightening shaft.

[0036] The setting of the limiting guide sleeve 200 avoids direct wear of the base plate seat 100 by the tightening shaft during operation, thereby increasing the service life of the base plate seat 100. The limiting guide sleeve 200 and the base plate seat 100 are easy to assemble and disassemble, easy to replace, and easy to process, which improves production efficiency and protects the equipment. The tooling plate thus formed can significantly reduce the alarm rate when the tightening machine is working, increase work efficiency, and improve the production capacity of the crawler.

[0037] In some of the embodiments, Figure 1 , Figure 4 and Figure 5 As shown, the base plate seat 100 and the limiting guide sleeve 200 are made of stainless steel or aluminum alloy. Specifically, the base plate seat 100 can be made of a steel plate with a length of 450×width of 275×thickness of 15, and is provided with corresponding positioning holes 101. By adding the limiting guide sleeve 200 in each positioning hole 101, the heat treatment of the base plate seat 100 can be avoided, and the base plate seat 100 can be prevented from bending and deformation.

[0038] In order to realize the installation and fixation of each limiting guide sleeve 200, four threaded holes 102 arranged at equal distances are respectively opened at the four peripheral positions of each positioning hole 101 on the base plate seat 100. The four corners of each limiting guide sleeve 200 are fixedly installed in the four threaded holes 102 around the corresponding positioning hole 101 by using locking bolts 300, so that the limiting guide sleeve 200 and the base plate seat 100 are fixedly connected as a whole, so as to prevent the limiting guide sleeve 200 from being offset when the tightening machine is running.

[0039] It is obvious that, on the basis of ensuring that the overall structural strength of the base plate 100 meets the standard, in order to reduce production costs and realize the lightweight structural design of the tooling plate, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a plurality of hollows 103 of different shapes may be opened on the base plate seat 100 , and each of the hollows 103 is located between two adjacent positioning holes 101 .

[0040] In addition, in order to realize the installation and fixation of the tooling plate on the four-axis tightening machine equipment, a plurality of installation holes 104 arranged at intervals are transversely opened at the front edge of the base plate 100, and the tooling plate is fixedly installed on the slide of the four-axis tightening machine through the pins inserted in the installation holes 104. Specifically, the limit pressure strip bolts at both ends of the tightening tooling plate on the tightening machine slide are loosened, and the combined four-axis tightening machine tooling plate is inserted, and the two installation holes (104) are aligned with the positioning spring pins on the slide and inserted into the installation holes (104) to confirm the position of the combined four-axis tightening machine tooling plate.

[0041] At the same time, the left and right sides of the base plate 100 are respectively provided with limited pressure platforms 105, which are fixed on the slide of the four-axis tightening machine through the limited pressure platforms 105 at both ends. After the latch is inserted into the mounting hole (104), the "shaped pressure strip bolts" on the slide are tightened to press the limited pressure platform (105) to prevent the combined four-axis tightening machine tooling plate from shaking. It is worth noting that the installation and fixing method of the base plate 100 on the slide of the four-axis tightening machine is the same as the installation method of the existing four-axis tightening machine tooling plate, which is a known conventional technical means and will not be described in detail here.

[0042] In some of the embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the limiting guide sleeve 200 is composed of a limiting cover plate 201 and a limiting cylinder 202 connected in one piece. The limiting cover plate 201 is a hollow square round plate structure, and its bottom is coaxially arranged on the top of the limiting cylinder 202, forming a ring-shaped T-shaped structure as a whole. The limiting cover plate 201 at the upper end of the T-shape is fixedly mounted on the top of the base plate seat 100, and the limiting cylinder 202 at the lower end of the T-shape is coaxially embedded in the positioning hole 101, thereby avoiding direct contact between the tightening shaft and the base plate seat 100, and then avoiding direct wear on the base plate seat 100.

[0043] In order to cooperate with the locking bolt 300 to achieve the fixation of the base plate seat 100 and the limiting guide sleeve 200, countersunk holes 203 are respectively opened at the four corners of the limiting cover plate 201. The lower end of the locking bolt 300 passes through the countersunk hole 203 and is locked and fixed in the corresponding threaded hole 102 on the base plate seat 100. When the limiting guide sleeve 200 is worn and needs to be replaced, the locking bolt 300 is screwed out, and the limiting guide sleeve 200 can be removed from the positioning hole 101, which is simple to disassemble and assemble, easy to replace, and easy to process.

[0044] In some of the embodiments, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8As shown, in order to facilitate the normal operation of the tightening shaft, the inner hole diameter of the limiting cover plate 201 is required to be the same as the inner hole diameter of the limiting cylinder 202, the tightening shaft is passed through the inner holes of the limiting cover plate 201 and the limiting cylinder 202, and the top opening of the inner hole of the limiting cover plate 201 can be set to a chamfer 204.

[0045] In addition, in terms of the size design of the limiting guide sleeve 200, in order to be able to coordinate the installation with the base plate seat 100, the thickness of the limiting cover plate 201 is designed to be 1 / 3-2 / 3 of the thickness of the base plate seat 100, and the axial height of the limiting cylinder 202 is designed to be equal to the thickness of the base plate seat 100, so that the limiting cylinder 202 can be completely installed in the positioning hole 101.
