Description

Technical Field

[0001] The invention relates to a slideway plate positioning device, belonging to the field of pipe upper plate positioning. Background Art

[0002] With the progress of society and the development of the petrochemical industry, various large and super-large structural parts continue to appear. Such structural parts can bring huge economic benefits, but at the same time they also bring great pressure to transportation. Some structural parts exceed the maximum limit in the current road transportation traffic management regulations. When customers transfer such structural parts, they need to pay a large amount of fines to the traffic management department. In order to continuously meet customer needs, improve the efficiency of structural parts installation and disassembly, and reduce the transportation cost of structural parts, new structural forms are gradually developed. The new structural parts have the function of variable cross-section. They are assembled by several single-leaf structures through pins. During transportation, only the single-leaf structures at both ends need to be disassembled, and the remaining single-leaf structures are not disassembled. The cross-section of the entire structural part can be reduced, so that the cross-section size is controlled within the range of traffic management regulations, thereby avoiding fines caused by exceeding the regulations. One of the key points affecting the expansion and retraction of the entire structural part is the main slide plate on the single leaf. The center plane distance between the two main slide plates on the single leaf needs to be controlled within a small range, otherwise it will affect the normal sliding of other structural parts along the slide. During the production of the first set, the distance between the main slide plates was measured by marking with a tape measure. Because the distance between the two slide plates was large and there was no fixing device, one main slide plate was first marked on the pipe, and then the other main slide plate was marked. Finally, the distance between the two main slide plates was adjusted to the drawing requirements by hammering. In addition, a right-angle ruler was used to adjust the verticality of the two slide plates. After the welding was completed, the holes on the main slide plate and the oblong holes on the slide were processed by machine tools. Due to the insufficient rigidity of the oblong holes of the main slide plate, there was an obvious vibration scene in the main slide plate during the machining process, resulting in very low machining efficiency, which seriously restricted the production efficiency of the entire structural parts. Now a set of tooling is designed to improve the efficiency of the main slide plate, and at the same time adjust the main slide plate from the original component machining to part machining. The use of this tooling can ensure that the dimensions after welding meet the requirements of the drawings, significantly improving production efficiency. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a slide plate positioning device. A set of tooling is designed to improve the assembly efficiency of the main slide plate. At the same time, the main slide plate is adjusted from the original component machining to part machining. The use of this tooling can ensure that the dimensions after welding meet the requirements of the drawings, thereby significantly improving production efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a slide plate positioning device, comprising a slide plate and a structural member, characterized in that it also comprises a positioning device connected to the structural member; the positioning device comprises a main positioning plate, a connecting pipe and a positioning pipe;

[0005] The connecting pipe comprises a connecting pipe 1 connecting two symmetrical main positioning plates and a connecting pipe 2 connecting the connecting pipe 1 and the positioning pipe; two legs are arranged at both ends of the bottom of the connecting pipe 1; and two legs symmetrical to the bottom of the positioning pipe are arranged at the bottom of the connecting pipe 1;

[0006] The main positioning plate is arranged at both ends of the connecting pipe; the front end of the main positioning plate is in the shape of a semicircular body, and a joint hole connected to the structural member is arranged in the middle; a boss is arranged at the rear end of the main positioning plate; a groove is arranged in the middle of the boss; the width of the groove is consistent with the thickness of the slide plate, and the center distance between the two grooves is the same as the center distance of the slide plate in the structural member;

[0007] The positioning device is connected to the joint hole of the structural member through the joint hole, and is clamped in the two side ear plates located on the same side of the structural member through the boss on the main positioning plate; an ear plate groove is respectively provided on both sides of the boss near the edge of the boss;

[0008] The two side end surfaces of the positioning tube are fitted and connected to the side surfaces of the slide plate; the tail end of the slide plate is arranged between the two ear plates of the structural member.

[0009] Furthermore, the main positioning plate is arranged at both ends of the connecting pipe and is fixedly connected.

[0010] Furthermore, the positioning device is overall symmetrically distributed on the left and right.

[0011] The beneficial effects of the present invention are: the main slide plate is adjusted from the original component machining to part machining, and the use of this tooling can ensure that the dimensions after welding meet the requirements of the drawings, significantly improving production efficiency. It solves the problem of joining two parts with large spacing and strict spacing size requirements in the structural parts. In addition, it can realize that some dimensions that originally require overall machining of the structural parts are adjusted to part machining, and then welded using the positioning device. In addition, the plates on the two tubes have position accuracy requirements. Since the outer surface of the pipe is arc-shaped, it is not easy to mark and join points to ensure the position size. This positioning device can effectively solve such problems. Compared with the current situation without a positioning device, the welding and machining time of the structural parts can be significantly shortened, the joining and machining efficiency of the structural parts can be improved, and the large manual marking error caused by the large spacing between the two parts can be avoided, resulting in the actual size of the slide plate exceeding the tolerance range required by the drawing, and tedious adjustment is required.

[0023] The main positioning plate 2 is arranged at both ends of the connecting pipe 3 and is fixedly connected.

[0024] The positioning device 1 is overall symmetrically distributed.

[0025] Tooling model such as Figure 1 As shown, the two joint holes 2-1 in the positioning device 1 are the same as the hole diameter and hole center distance in the structural member. A groove 6-1 is opened at the center position of the boss 6 on the main positioning plate 2. The width of the groove 6-1 is consistent with the thickness of the slide plate. The center distance between the two grooves 6-1 is the same as the center distance of the slide plate in the structural member, and the center distance between the bottom surface of the groove 6-1 and the hole on the slide plate is equal to the distance between the joint hole and the end face of the slide plate in the single-leaf structure.
