Abstract
Description
Technical Field
[0001] This utility model relates to the field of nitriding fixture technology, specifically a sleeve-type return disk ion nitriding fixture. Background Technology
[0002] A typical plunger pump consists of a housing, a shaft, and components mounted on the shaft such as a swashplate, return plate, cylinder block, and distributor plate. The return plate, which comes into contact with the shaft and slippers, is frequently subjected to varying degrees of wear or breakage due to harsh operating conditions, affecting the normal use of the components. Ion nitriding treatment can improve the surface hardness of the return plate, mitigating wear to some extent. The technical requirement for ion nitriding is that the spacing between components in all six directions must be consistent when suspended to ensure uniform nitriding effect.
[0003] Traditionally, the fixtures used for ion nitriding of return disks are designed with beams of uniform height. This usually limits the hanging of return disks to the same model. If different sizes of return disks are attempted to be hung, the spacing between the upper and lower return disks will be inconsistent, which will affect the ion nitriding effect and cannot meet the mixed loading requirements of products with different structures. Designing and manufacturing fixed fixtures according to the structure of each return disk is time-consuming and labor-intensive. Therefore, a sleeve-type return disk ion nitriding fixture is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a sleeve-type return disk ion nitriding fixture to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sleeve-type return disk ion nitriding hanger, comprising multiple sets of supports, adjacent supports being connected by a hanger, each support comprising two columns perpendicular to the ground, the two columns being connected to each other by multiple connecting rods, at least one sleeve being fitted on the outer circumferential surface of each column, the end face of the sleeve perpendicular to the ground having a strip groove, the end face of the sleeve perpendicular to the strip groove being connected to the end of the hanger, and a hanging beam for loading the return disk being installed on the hanger.
[0006] As a further embodiment of this utility model: the end face where the connecting rod connects to the column is on the same side as the end face where the strip groove is located.
[0007] As a further aspect of this utility model, the width of the strip groove is greater than the diameter of the end of the connecting rod.
[0008] As a further embodiment of this utility model: the sleeve has a through cavity along its length, and the through cavity is connected to the strip groove.
[0009] As a further embodiment of this utility model: the inner diameter of the through cavity is adapted to the outer diameter of the column.
[0010] As a further embodiment of this utility model: both ends of the hanging beam are provided with limiting grooves, and the limiting grooves are located in the area where the hanging beam is connected to the hanging frame.
[0011] As a further embodiment of this utility model: multiple positioning grooves are provided on the hanging beam, and all of the multiple positioning grooves are provided on the upper surface of the hanging beam.
[0012] As a further embodiment of this utility model: the plurality of positioning grooves are arranged at equal intervals, and the plurality of positioning grooves are all semi-circular arc-shaped.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This application allows for adjustment of the spacing between adjacent hanging beams by fitting sleeves of different heights onto the outer perimeter of the column. This accommodates different models of return plates and ensures consistent spacing between them in six directions during hanging, thus fulfilling the mixed-installation requirements of various structural products using the ion nitriding return plate hanger.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 In this embodiment of the utility model, a sleeve-type return disk ion nitriding fixture is characterized by comprising multiple sets of supports, with adjacent supports connected by a hanger 4. Each support includes two vertical columns 1 perpendicular to the ground, connected to each other by multiple connecting rods 2. The connecting rods 2 are all made of metal and serve to fix the columns 1, ensuring the stability and robustness of the overall structure. At least one sleeve 3 is fitted onto the outer circumference of each column 1. The number of sleeves 3 is not limited; sleeves of different heights can be selectively fitted according to actual conditions. The height of the sleeve 3 is the outer diameter of the return disk + 30mm, preventing contact between the return disks and thus avoiding potential interference or damage. Each sleeve 3 has a through cavity 3-1 along its length. The inner diameter of the cavity 3-1 is adapted to the outer diameter of the column 1 so that the sleeve 3 can fit tightly on the outer circumference of the column 1. The end face of the sleeve 3 perpendicular to the ground is provided with a strip groove 3-2. The cavity 3-1 is connected to the strip groove 3-2. The sleeve 3 can be stacked along the length of the column 1. The end face of the connecting rod 2 connected to the column 1 is on the same side as the end face of the strip groove 3-2. The width of the strip groove 3-2 is greater than the diameter of the end of the connecting rod 2, ensuring that the connecting rod 2 connected to the column 1 will not obstruct the sleeve 3 from falling smoothly and fitting onto the column 1. The end face of the sleeve 3 perpendicular to the strip groove 3-2 is connected to the end of the bracket 4. Both ends of the bracket 4 are connected to the sleeve 3, which serves to support the hanging beam 5. The bracket 4 is equipped with the hanging beam 5 for loading the return plate.
[0023] like Figure 5 As shown, when the structural strength of the four columns 1 is insufficient to support the weight of the fully loaded product, the hanging beam 5 may bend downwards in the middle due to its large span and excessive weight. In the long run, this will lead to deformation or even collapse. An additional column can be added in the middle of the original front and rear or left and right rows of columns, that is, a total of six columns are used to construct the overall frame. This provides an additional stress point in the middle of the hanging beam 5, thereby effectively distributing the load, enhancing the stability and load-bearing capacity of the entire structure, and preventing the hanging beam 5 from deforming or collapsing.
[0024] Please see Figure 3In one embodiment, preferably, both ends of the hanging beam 5 are provided with limiting grooves 5-1. The limiting grooves 5-1 are located in the area where the hanging beam 5 is connected to the hanging frame 4. The hanging beam 5 is connected to the hanging frame 4 through the limiting grooves 5-1 at both ends. This design allows the hanging beam 5 to move along the length of the hanging frame 4. This structure not only ensures a stable connection between the hanging beam 5 and the hanging frame 4, but also provides flexibility in adjusting the position of the hanging beam. Multiple positioning grooves 5-2 are provided on the hanging beam 5. The multiple positioning grooves 5-2 are all provided on the upper surface of the hanging beam 5. The distance between every two adjacent positioning grooves 5-2 is 30mm. The multiple positioning grooves 5-2 are equally spaced and are all semi-circular arc-shaped.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
