Description

Technical Field

[0001] The utility model relates to the technical field of installation workpieces, and particularly relates to a workpiece for installing a pipeline spring piece. Background Technique

[0002] In the field of mechanical equipment assembly, the assembly of spring pieces and pipelines is very common. Among them, bayonets are opened on the side walls of the pipelines, and a chuck matching the bayonets is also arranged at one end of the spring piece.

[0003] At present, when a spring piece needs to be installed into a pipeline, a staff member will use a rod-shaped object with a fixed length to push the spring piece into the position to be installed on the pipeline. In order to avoid the shaking of the spring piece during installation, a clamping notch can also be opened at the head of the rod-shaped object, and the spring piece is placed in the clamping notch to improve the stability of the spring piece during installation.

[0004] However, during actual operation, the staff often cannot accurately control the height at which the spring piece extends into the pipeline, resulting in the spring piece sliding across the bayonet due to the rod-shaped object extending too fast, ultimately leading to low assembly efficiency. For this reason, a workpiece for installing a pipeline spring piece is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a workpiece for installing a pipeline spring piece to solve the problem of low assembly efficiency caused by the fact that manual operation cannot accurately control the height at which the spring piece extends into the pipeline in the above-mentioned background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A workpiece for installing a pipeline spring piece includes a bottom plate. A rotating cylinder is rotatably connected to the center of the top of the bottom plate. A threaded rod is threadedly connected inside the rotating cylinder. A sliding rod is slidably connected inside the threaded rod. A U-shaped chuck is fixedly connected to the top of the sliding rod. A limiting short shaft is fixedly connected to the outer side wall of the threaded rod near the rotating cylinder. A limiting rod is fixedly connected to the top surface of the bottom plate at a position below the outer end of the limiting short shaft. The limiting short shaft is slidably connected to the limiting rod. A limiting disk is fixedly connected to the top end of the limiting rod. A clamping component is arranged on the threaded rod for fixing the relative positions of the threaded rod and the sliding rod. The clamping component includes a screw. A plurality of internal fixing ports are arranged on the sliding rod. An external fixing port is opened on the threaded rod. A nut is fixedly connected to one end of the threaded rod where the external fixing port is located. The screw is inserted into the external fixing port and the internal fixing port and then threadedly connected to the nut.

[0007] Preferably: A rotating handle is sleeved on the outer side wall of the rotating cylinder. A sliding port is opened at the outer end of the limiting short shaft. The limiting rod passes through the sliding port.

[0008] Preferably, a through-rotation opening is formed at the center of the top surface of the bottom plate. A rotation concave ring groove is formed on the inner side wall of the through-rotation opening. An inner rotation ring block is sleeved on the outer side wall of the rotating cylinder at the rotation concave ring groove, and the inner rotation ring block extends into the rotation concave ring groove.

[0009] Preferably, a plurality of the inner fixing openings are arranged vertically and equidistantly, and the inner fixing openings penetrate through the sliding rod.

[0010] Preferably, the outer fixing opening and the inner fixing opening have the same aperture size, and the outer fixing opening penetrates through the threaded rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: By lifting the sliding rod upward or pushing the sliding rod downward, and fixing the relative positions of the threaded rod and the sliding rod through the clamping assembly, the height of the U-shaped clamping block can be greatly adjusted. Then, by rotating the rotating cylinder, the threaded rod slowly rises or falls, so as to finely adjust the height of the U-shaped clamping block, so that the clamping head on the spring piece just reaches and is stuck into the clamping opening formed on the outer wall of the pipeline, successfully realizing the quick installation of the spring piece.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0018] Embodiment 1:

[0019] Referring to Figures 1-4 as shown, the present utility model provides a technical solution for a workpiece used for installing a pipeline spring piece:

[0020] A workpiece for installing a pipeline spring piece is used to assist in installing the spring piece inside the pipeline. Referring to Figure 4 as shown, one end of the spring piece is provided with a chuck, and a bayonet is opened on the side wall of the pipeline. When the chuck is stuck into the bayonet, it means that the spring piece is successfully installed. This workpiece includes a bottom plate 1. A rotating cylinder 102 is rotatably connected to the center of the top of the bottom plate 1. A threaded rod 2 is threadedly connected inside the rotating cylinder 102. Among them, the threaded rod 2 is columnar, and a sliding rod 3 is slidably connected inside the threaded rod 2. Among them, the sliding rod 3 is columnar, and a U-shaped chuck 302 is fixedly connected to the top of the sliding rod 3 for placing the spring piece. A limiting short shaft 201 is fixedly connected to the outer side wall of the threaded rod 2 near the rotating cylinder 102. A limiting rod 101 is fixedly connected to the top surface of the bottom plate 1 at a position below the outer end of the limiting short shaft 201. The limiting short shaft 201 is slidably connected to the limiting rod 101. A limiting disc 105 is fixedly connected to the top end of the limiting rod 101 for restricting the pipeline from moving downward continuously, facilitating the staff to more clearly master the length of the spring piece extending into the pipeline. A clamping component is arranged on the threaded rod 2 for fixing the relative positions of the threaded rod 2 and the sliding rod 3.

[0021] Among them, it should be added that referring to Figure 3 as shown, a through-rotating port is opened at the center of the top surface of the bottom plate 1, and a rotating concave ring groove is opened on the inner side wall of the through-rotating port. An inner rotating ring block 104 is sleeved on the outer side wall of the rotating cylinder 102 at the rotating concave ring groove. The inner rotating ring block 104 extends into the rotating concave ring groove. Through such a setting, the rotating cylinder 102 can rotate on the bottom plate 1 without detachment.

[0022] Referring to Figure 2 as shown, the clamping component includes a screw 204 which can be taken out. A plurality of inner fixing ports 301 are arranged on the sliding rod 3, and an outer fixing port 202 is opened on the threaded rod 2. A nut 203 is fixedly connected to one end of the threaded rod 2 where the outer fixing port 202 is located. The relative positions of the threaded rod 2 and the sliding rod 3 of this workpiece are fixed by inserting the screw 204 into the outer fixing port 202 and the inner fixing port 301 and then threadedly connecting with the nut 203. Among them, the inner fixing port 301 penetrates through the sliding rod 3, and the outer fixing port 202 penetrates through the threaded rod 2. It should be added that the threaded rod 2 is provided with a through hole in the middle.

[0023] Working principle: Through the setting of the clamping component, during use, only need to unscrew the screw 204 from the nut 203, then the slide bar 3 can be lifted upward or pushed downward, thereby controlling the height of the U-shaped clamping block 302. When the outer fixing port 202 overlaps with another inner fixing port 301, the user can insert the screw 204 into the outer fixing port 202 and the inner fixing port 301 and finally screw it into the nut 203, successfully achieving the fixation of the relative positions of the threaded rod 2 and the slide bar 3, greatly adjusting the height of the U-shaped clamping block 302, thereby accelerating the installation efficiency of the spring piece.

[0024] When this workpiece is working, adjust the length of this workpiece extending into the pipeline according to the distance from the clamping port on the pipeline to the lower port of the pipeline. By lifting the slide bar 3 upward or pushing the slide bar 3 downward, and fixing the relative positions of the threaded rod 2 and the slide bar 3 through the clamping component to greatly adjust the height of the U-shaped clamping block 302. Then, by rotating the rotating cylinder 102, since the limit short shaft 201 slides on the limit rod 101, the threaded rod 2 slowly rises or falls, thereby finely adjusting the height of the U-shaped clamping block 302. Then place the spring piece in the U-shaped clamping block 302, and both ends of the spring piece extend out from both sides of the U-shaped clamping block 302. Move the pipeline downward from the U-shaped clamping block 302 until the lower port of the pipeline touches the limit disk 105. At this time, the clamping head on the spring piece just reaches the clamping port opened on the outer wall of the pipeline and snaps in, successfully achieving the quick installation of the spring piece. The structural setting is simple and efficient, can effectively improve the assembly efficiency between the spring piece and the pipeline, and is suitable for popularization and use.

[0025] It should be added that when installing the spring piece on a certain pipeline for the first time, first estimate the length of this workpiece extending into the pipeline according to the distance from the clamping port on the pipeline to the lower port of the pipeline, and lift the slide bar 3 upward or push the slide bar 3 downward, and fix it through the clamping component. Then directly move the pipeline downward from the U-shaped clamping block 302. When it touches the limit disk 105, if the clamping head of the spring piece does not come out of the clamping port of the pipeline, then make fine adjustment at this time. After successful installation, this workpiece can continuously repeat the installation of the spring piece, greatly improving the installation efficiency of the spring piece.

[0026] Embodiment 2:

[0027] Refer to Figure 1 As shown, a rotating handle 103 is sleeved on the outer side wall of the rotating cylinder 102. A sliding port is opened at the outer end of the limit short shaft 201, and the limit rod 101 passes through the sliding port. Among them, it should be added that the rotation of the rotating handle 103 will not be blocked by the limit rod 101. The limit rod 101 fits against the inner wall of the sliding port, making the lifting and lowering of the threaded rod 2 more stable. There is no thread provided on the outer surface of the threaded rod 2 above the limit short shaft 201.

[0028] With such a setting, the staff can conveniently control the rotation of the rotating cylinder 102 by turning the handle 103, which improves the convenience during fine adjustment of this workpiece.

[0029] Embodiment 3:

[0030] Refer to Figure 2 As shown, several internal fixing ports 301 are arranged vertically at equal distances, and the aperture sizes of the external fixing port 202 and the internal fixing port 301 are equal. With such a setting, the user can anticipate the position of the internal fixing port 301, which facilitates the alignment of the internal fixing port 301 and the external fixing port 202. Since their aperture sizes are equal, the two can be inserted and fixed by the screw 204 against the inner wall, thereby making the relative position between the threaded rod 2 and the sliding rod 3 more stable.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
