The steering mechanism generally includes a steering cylinder and a fixing frame for installing the steering cylinder. The fixing frame is welded by a steering cylinder seat and a bracket.

[0003] like Figure 1 The structure diagram of the steering oil cylinder seat 6 is shown. The steering oil cylinder seat 6 is a U-shaped structure, and the two side surfaces are provided with oil cylinder mounting holes 61. When in use, the steering oil cylinder seat 6 can be welded to the bracket. When the existing steering oil cylinder seat 6 is welded and fixed, the installation position of the steering oil cylinder seat on the bracket is determined by manual measurement and marking, and then welding is performed. However, this welding method has the following main defects: since manual measurement and marking positioning are required, it is time-consuming and labor-intensive, resulting in low work efficiency, and deformation is easy to occur after welding, and the dimensional accuracy cannot be guaranteed, which affects the subsequent use of the equipment. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a steering cylinder seat positioning device to solve the problems of low working efficiency and poor welding quality during the steering cylinder seat welding operation.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1-5 As shown, a steering cylinder seat positioning device comprises:

[0033] Base 1;

[0034] A first pressing member 2, which is disposed at the top of the base 1, and is provided with a first positioning hole 21 corresponding to the cylinder mounting hole 61;

[0035] The second pressing member 3 has a second positioning hole 31 extending radially therethrough on its surface. The second positioning hole 31 is arranged corresponding to the cylinder mounting hole 61. The second pressing member 3 is located above the first pressing member 2 and cooperates with the first pressing member 2 to press and fix the two side surfaces of the steering cylinder seat 6.

[0036] The positioning member 4 has a positioning shaft 41 at one end and a limiting portion 42 at the other end. The positioning shaft 41 is inserted into the second positioning hole 31, the cylinder mounting hole 61 and the first positioning hole 21 in sequence. The limiting portion 42 abuts against the upper surface of the second pressing member 3.

[0037] The limiting member 5 is disposed on the first pressing member 2 , and is used to limit the steering cylinder seat 6 from rotating around the positioning shaft 41 .

[0038] Among them, the base 1 can include a bottom plate 11 and a support member 12. The bottom plate 11 can be set as a square steel plate. To facilitate the fixation of the base 1, connecting holes for installing fixing bolts can be set at the left and right ends of the bottom plate 11. The support member 2 can be set as a square tube, and its bottom end can be fixed to the bottom plate 11 by welding.

[0039] Among them, the first clamping member 2 is used to support the steering cylinder seat 6. The first clamping member 2 can be set as a square steel plate, and its bottom surface can be connected to the top of the support member 12 by welding. The first positioning hole 21 can be set at the center position of the first clamping member 2 and correspond to the cylinder mounting holes 61 on the two side surfaces of the steering cylinder seat 6.

[0040] The second pressing member 3 may be a square steel plate, and the second positioning hole 31 may be arranged at the center of the second pressing member 3 corresponding to the cylinder mounting hole 61 on the steering cylinder seat 6 .

[0041] Among them, the positioning member 4 is used to position and fix the first clamping member 2, the steering cylinder seat 6 and the second clamping member 3, the outer diameter of the positioning shaft 41 is adapted to the inner diameter of the cylinder mounting hole 61, the outer diameter of the limiting portion 42 is larger than the inner diameter of the cylinder mounting hole 61, and the limiting portion 42 abuts against the top of the second clamping member 3 to limit the up and down movement of the second clamping member 3.

[0042] Among them, the limit member 5 is used to limit the rotation of the steering cylinder seat 6 around the positioning axis 41. The limit member 5 can be two limit plates vertically arranged on the upper surface of the first clamping member 2. The two limit plates are respectively located on the left and right sides of the first positioning hole 21. The distance between the two limit plates is adapted to the width dimension of the steering cylinder seat 6. When in use, the steering cylinder seat 6 can be clamped between the two limit plates.

[0043] Of course, the limiting member 5 can also be set as a side baffle, see Figure 4 As shown, one end of the side baffle is fixed to a side surface of the first clamping member 2 and the other end extends upward to abut against the bottom surface of the steering cylinder seat 6. The height of the upward extension of the side baffle can be set according to actual needs. It should be avoided that it is too high to interfere with subsequent welding work, or too low to achieve the purpose of limiting the rotation of the steering cylinder seat 6.

[0044] The working principle of this implementation is as follows:

[0045] When in use, first place one side of the steering cylinder seat 6 to be positioned on the first clamping piece 2 and position it by the limiter 5, then adjust the cylinder mounting hole 61 on the side of the steering cylinder seat 6 to align with the first positioning hole 21, and then place the second clamping piece 3 on the other side of the steering cylinder seat 6, so that the second clamping piece 3 cooperates with the first clamping piece 2, and the two side surfaces of the steering cylinder seat 6 are clamped and fixed. At the same time, adjust the second clamping piece 3 to align the second positioning hole 31 with the cylinder mounting hole 61, and then insert the positioning shaft 41 of the positioning piece 4 into the second positioning hole 31, the cylinder mounting hole 61 and the first positioning hole 21 in turn, so that the steering cylinder seat 6 can be positioned and fixed.

[0046] It can be seen that the steering cylinder seat positioning device provided by the present invention has a simple structure and is quick and convenient to clamp. Through the cooperation of the first clamping piece, the second clamping piece and the positioning piece, the two side surfaces of the steering cylinder seat and the cylinder mounting hole can be quickly and accurately positioned and fixed, which not only facilitates subsequent operations by the staff, but also eliminates the marking and positioning link, thereby effectively improving work efficiency. By arranging a limit piece on the first clamping piece, the steering cylinder can be limited and fixed to prevent it from rotating, thereby further improving the accuracy of product positioning and ensuring the quality of the product.

[0047] As a further preferred embodiment of the present embodiment, the first positioning hole 21 may be a through hole radially penetrating the surface of the first pressing member 2 , so as to facilitate the upward and downward adjustment of the positioning member 4 .

[0048] In order to prevent the positioning member 4 from being loosened, the first positioning hole 21 can be set as a threaded hole, and the bottom end of the positioning shaft 41 connected to the first positioning hole 21 is set as a threaded rod matching the threaded hole.

[0049] Furthermore, a gripping portion 43 may be provided at the top end of the positioning member 4 away from the positioning shaft 41 , so that the staff can grip the positioning member 4 conveniently.

[0050] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0051] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above are only preferred implementation methods of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
