Description

Technical Field

[0001] This utility model relates to the field of oil suction pipe assembly. More specifically, this utility model relates to an assembly fixture for an oil suction pipe assembly. Background Technology

[0002] The oil suction pipe assembly consists of two parts: the oil suction pipe and the blade. The blade in the middle is interference-fitted with the oil suction pipe.

[0003] When assembling the oil suction pipe assembly, the blades need to be forcibly inserted into the suction pipe. This is typically done manually using a 7mm round rod to push the blades into the predetermined position within the pipe, which is inefficient, taking 30 seconds to assemble one unit. Furthermore, the operator's technique can easily lead to misalignment, resulting in inconsistent quality. During assembly, the blades need to be aligned with the suction pipe; if done manually, this can easily result in the blades being installed crookedly or to the required depth. Utility Model Content

[0014] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0016] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0017] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0018] like Figure 1-2 As shown, a preferred embodiment of this utility model provides an oil suction pipe assembly assembly fixture. The oil suction pipe assembly 12 includes an oil suction pipe 1 and a blade 2, wherein the blade 2 is inserted into the oil suction pipe 1. The oil suction pipe assembly assembly fixture includes: Lower base 3; The lower fixing plate 4 is disposed on the lower base 3, and the lower fixing plate 4 is provided with a positioning structure for positioning the oil suction pipe assembly; Upper pad 5, the upper pad 5 is located above the lower fixed plate 4, and the upper pad 5 can be raised and lowered in the vertical direction relative to the lower fixed plate 4; There are multiple pressing punches 6, which are fixed to the side of the upper pad 5 facing the lower fixed plate. The position of the pressing punches 6 corresponds one-to-one with the position of the blades on the lower fixed plate. They are used to push the blades into the oil suction pipe when the upper pad descents.

[0019] During operation, the positioning suction pipe assembly is first placed on the positioning structure on the lower fixed plate 4. The upper pad 5 is driven to move downwards vertically. At this time, the pressure punch 6 descends synchronously with the upper pad 5, and its working section first contacts the upper surface of the blade. As the upper pad continues to descend, the pressure punch applies vertical downward pressure to the blade. Under the action of pressure, the blade overcomes the friction with the inner wall of the suction pipe and is gradually pushed into the suction pipe. When the pressure punch descends to the preset position, the blade is completely inserted into the suction pipe and reaches the specified depth. The upper pad stops descending and returns to its original position, completing one assembly.

[0020] Another technical solution also includes a guide assembly, which includes a guide post 7 and a guide sleeve 8. The guide post is vertically fixed on the lower base, and the guide sleeve is fixed on the upper pad and corresponds one-to-one with the guide post. The guide post is sleeved inside the guide sleeve, and the guide sleeve is sleeved outside the guide post and slides in cooperation with the guide post to guide the upper pad to rise and fall.

[0021] During operation, when the upper pad 5 is raised and lowered under the drive of external power, the guide sleeve 8 moves downward synchronously with the upper pad and slides axially along the guide section of the guide post, thereby ensuring that the upper pad always moves in the vertical direction and the axis of the pressing punch remains coincident with the positioning center of the blade.

[0022] In another technical solution, the upper pad is provided with a mounting handle 9 on the side opposite to the lower fixed plate, and the mounting handle 9 is used to connect to the output end of the press.

[0023] In another technical solution, a lower pad 10 is provided between the lower base 3 and the lower fixing plate 4, and the lower fixing plate 4 is supported on the lower base 3 by the lower pad 10.

[0024] During operation, the lower pad 10 bears the weight of the lower fixed plate and the oil suction pipe assembly 12, and transfers the load to the lower base. At the same time, its own thickness supports the lower fixed plate to a preset height. When different lengths of oil suction pipes need to be installed, the lower pad of different thicknesses can be replaced.

[0025] In another technical solution, there are at least two guide posts, and all the guide posts 7 are distributed at intervals along the circumference of the lower fixing plate.

[0026] In the above technical solution, multiple circumferentially distributed guide posts are used to form symmetrical guiding constraints, so that the upper pad remains balanced during lifting and stress, and avoids eccentric loading.

[0027] Another technical solution also includes an upper fixing plate 11, which is disposed in contact with the lower surface of the upper pad plate. One end of the pressing punch is fixedly connected to the upper pad plate, and the other end passes through the upper fixing plate and extends into the oil suction pipe.

[0028] During operation, the pressure punch 6 descends synchronously with the upper pad and the upper fixed plate 11. When the working section of the pressure punch 6 contacts the blade and applies pressure, the pressure punch 6 will be subjected to the reaction force of the blade. At this time, the upper fixed plate 11 applies radial constraint to the working section of the pressure punch 6 through the through hole to prevent it from bending or deviating due to the force.

[0029] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
