Description

Technical Field

[0002] With the continuous development of industrial technology, turbine casings are increasingly used in various fields.

[0003] However, in the processing of turbine casing, positioning has always been a key factor affecting processing quality and efficiency. Traditional positioning devices often position the turbine casing from the outer side, which makes it impossible for workers to process the outside of the turbine casing and cannot meet the modern industry's diversified processing needs for turbine casings.

[0004] In the prior art, a turbine casing bushing pressing device is disclosed with publication number "CN219189241U". In this utility model, a workbench is raised for a smaller turbine casing to make the turbine installation tighter, avoiding the possibility of gaps during installation which would require secondary rework. The pressing device can install turbines of more sizes, thereby improving the efficiency of the pressing. At the same time, the turbine casing and the turbine are placed from the outside, which ensures the safety of the staff to a certain extent.

[0005] However, since the turbine shell is positioned and restricted from directly above, this method will cause great inconvenience in the process of taking and placing the turbine shell, and it is difficult to fix the horizontal position when positioning the turbine shell, which may cause the position of the turbine shell to shift during actual use, resulting in damage to the turbine shell. Therefore, the existing equipment needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For example, see Figure 1-Figure 6 The utility model provides a turbine shell processing positioning assembly, including an operating table 1, the upper surface of which is fixedly provided with a mounting box 2 and a reference stopper 4, the upper surface of which is fixedly connected with a fixing table 6, and the upper surface of which is movably provided with a turbine shell 7;

[0029] A turning table 25 is arranged above the operating table 1, and four positioning plates 18 are arranged above the fixed table 6;

[0030] The upper surface of the operating table 1 has a pressing component for pressing down and fixing the turbine shell 7 and a positioning and contacting component for positioning and contacting the inside thereof;

[0031] The reference limiting device 4 is a hydraulic telescopic rod, and the height of the hydraulic box of the reference limiting device 4 is lower than the side surface of the turbine shell 7 .

[0032] In this embodiment, when the turbine shell 7 needs to be processed and positioned, the turbine shell 7 can be pre-positioned by passing the hydraulic telescopic rod of the reference limit device 4 through the threaded hole of the turbine shell 7, so as to facilitate the subsequent processing and positioning.

[0033] It is worth noting that two groups of reference limit devices 4 are symmetrically arranged. When the turbine housing 7 needs to be pre-positioned, the two reference limit devices 4 are started at the same time, and the telescopic rods move in opposite directions at the same time, so as to achieve the purpose of limiting.

[0034] For example 2, please refer to Figure 4-Figure 6 On the basis of the above embodiment, the positioning and resisting assembly comprises: a fixed box 8, the fixed box 8 is fixedly arranged on the upper surface of the fixed platform 6, the inner bottom surface of the fixed box 8 is fixedly connected with a first slide bar 9, the side surface of the first slide bar 9 is movably connected with a first spring 10, the upper end surface of the first slide bar 9 is slidably connected with a round table 11, the upper end surface and the lower end surface of the first spring 10 are respectively fixedly connected with the round table 11 and the fixed platform 6, the upper surface of the round table 11 is fixedly connected with a connecting column 12, and the upper surface of the connecting column 12 is fixedly connected with a pressing plate 13;

[0035] Four slide grooves 19 are provided on the upper surface of the fixed platform 6, and the interiors of the four slide grooves 19 are slidably connected to the limiting slide plates 17, and the upper end surfaces of the four limiting slide plates 17 are fixedly connected to the limiting plates 15, and the interiors of the four limiting plates 15 are fixedly connected to the second slide bars 14, and the side surfaces of the four limiting plates 15 are fixedly provided with second springs 16, and the interiors of the four second springs 16 are movably connected to the side surfaces of the four second slide bars 14;

[0036] The four second sliding rods 14 are slidably connected to the fixed box 8 at one side away from the truncated platform 11 , and the end surfaces of the four second sliding rods 14 away from the truncated platform 11 are fixedly connected to positioning abutment plates 18 .

[0037] In this embodiment, taking a single structure as an example, the pressing plate 13 will move downward after being pressed during use, and this displacement is limited by the first slide bar 9, and the first spring 10 cooperates so that the pressing plate 13 will move upward without the action of external force, so that the pressing plate 13 can move back and forth in the longitudinal direction, so that the round table 11 can move back and forth in the longitudinal direction through the transmission of the connecting column 12;

[0038] By setting the slide groove 19, the limiting slide plate 17 can only be displaced laterally. During the downward displacement of the truncated table 11, the second slide bar 14 can be displaced laterally by squeezing the second slide bar 14 and the cooperation of the limiting plate 15 and the limiting slide plate 17. By setting the second spring 16, the second slide bar 14 can be displaced laterally back and forth. In this way, the positioning plate 18 can be displaced laterally back and forth through the transmission of the second slide bar 14.

[0039] It is worth noting that the four positioning abutments 18 have the same working principle and extend outward or retract inward at the same time. A limiting block is provided on the lower end surface of the limiting slide plate 17 so that it will not escape from the inside of the slide groove 19 and can only move laterally.

[0040] For example 3, please refer to Figure 1-Figure 3 , based on the above embodiment, the pressing component includes:

[0041] A reciprocating motor 21, the reciprocating motor 21 is fixedly arranged on the inner bottom surface of the installation box 2, the output shaft of the reciprocating motor 21 is fixedly connected to a second connecting rod 24, one end of the second connecting rod 24 away from the output shaft of the reciprocating motor 21 is rotatably connected to a turning table 25, the inside of the turning table 25 is rotatably connected to a first connecting rod 23, one end of the first connecting rod 23 away from the turning table 25 is rotatably connected to a fixing plate 3, and the lower end surface of the fixing plate 3 is fixedly connected to the upper surface of the operating table 1;

[0042] The output shaft of the reciprocating motor 21 passes through the installation box 2 and is rotatably connected to the fixed plate 3. The first connecting rod 23 is rotatably connected to the installation box 2 and the fixed plate 3 through a rotating shaft.

[0043] In this embodiment: during actual use, the staff starts the reciprocating motor 21 to drive the second connecting rod 24 to perform reciprocating circular trajectory displacement. Through the circular trajectory displacement of the second connecting rod 24, the turning table 25 can be displaced in a reciprocating circular trajectory. Through the transmission of the turning table 25 and the cooperation of the fixed plate 3, the first connecting rod 23 can also be displaced in a reciprocating circular trajectory.

[0044] It is worth noting that when the turning table 25 moves in a reciprocating circular trajectory, the turning table 25 can press down and fix the turbine shell 7, and in the process of pressing down, it contacts the pressure plate 13, causing the pressure plate 13 to move downward. When the pressure plate 13 moves downward, the positioning plate 18 will extend and contact and fix the turbine shell 7. When the turning table 25 does not press down the turbine shell 7, the positioning plate 18 will shrink. In the process of placing the turbine shell 7, in actual use, since it is pressed down from the side, it is convenient for the operator to take and place the turbine shell 7, which brings great convenience and solves the problem of damage to the turbine shell 7 caused by the displacement of the position of the turbine shell 7 during use.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
