Description

Technical Field

[0001] This utility model relates to the field of nitriding fixture technology, specifically a 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, return plate ion nitriding typically uses a uniformly high hanging beam design, with some beams being detachable or movable. Height adjustment is usually achieved by fixing clips to the uprights, thus ensuring product versatility. However, since ion nitriding fixtures are usually exposed to high temperatures, they may deform due to heat and become unable to detach, or the clips may loosen and slip due to insufficient tightening at high temperatures. Additionally, the complex shape of the clips may cause arc discharge within the furnace. Therefore, a new return plate ion nitriding fixture is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a 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 return disk ion nitriding fixture, comprising two parallel side plate assemblies connected by multiple connecting rods, each side plate assembly comprising two vertical columns, a positioning plate between the two columns, multiple sets of channels on the positioning plate, and multiple hanging beams with ends extending into the channels between the two positioning plates, each channel comprising a main channel penetrating the top of the positioning plate and multiple first sub-channels and multiple second sub-channels respectively located on both sides of the main channel.

[0006] As a further embodiment of this utility model, the column is L-shaped.

[0007] As a further embodiment of this utility model, the column is provided with multiple through holes for the ends of the connecting rods to pass through.

[0008] As a further embodiment of this utility model: both ends of the connecting rod are provided with external threads, and both ends of the connecting rod are threaded with nuts.

[0009] As a further embodiment of this utility model: the end face of the column connected to the positioning plate is provided with a limiting member, the limiting member includes two symmetrically arranged limiting blocks, the opposite end faces of the two limiting blocks are designed to be inclined, and the outer periphery of the column is provided with an extension portion that contacts the end face of the limiting block at the near end position.

[0010] As a further embodiment of this utility model, the reserved space between the two limiting blocks is adapted to the side of the positioning plate.

[0011] As a further embodiment of this utility model, the hanging beam is provided with multiple grooves at equal intervals.

[0012] As a further embodiment of this utility model: the first sub-channel and the second sub-channel are alternately distributed from top to bottom, and each of the first sub-channel and the second sub-channel has one end connected to the main channel. The first sub-channel and the second sub-channel are alternately distributed from top to bottom along the length direction of the main channel.

[0013] As a further embodiment of this utility model: both the first sub-channel and the second sub-channel have a downward slope at the end away from the main channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This application sets multiple main channels on the positioning plate, allowing the hanging beam to move flexibly within the main channels. Multiple first and second sub-channels connected to the main channels provide a stable placement position for the hanging beam, replacing the detachable or movable buckles in traditional designs. This not only improves the ease of operation and product versatility, but also avoids buckle deformation caused by high temperatures, loosening and slippage due to insufficient tightening, and arc discharge problems caused by complex-shaped buckles in the furnace. As a result, the stability, safety, and reliability of the system are significantly improved. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-7 In this embodiment of the present invention, a return disk ion nitriding fixture includes two parallel side plate assemblies connected by multiple connecting rods 2. The number of connecting rods 2 is not limited; however, in this embodiment, preferably, there are four connecting rods 2, which are equally spaced. Each side plate assembly includes two vertical columns 1, with a positioning plate 3 between them. The positioning plate 3 has multiple sets of channels, the number of which is not limited and is determined by the width of the positioning plate 3 and the outer diameter of the return disk. Multiple rods with ends extending into the channels are provided between the two positioning plates 3. The hanging beam 7 has multiple grooves 8 at equal intervals to ensure that the return plate spacing on the same hanging beam 7 is the same. The channel includes a main channel 4 that runs through the top of the positioning plate 3 and multiple first sub-channels 5 and multiple second sub-channels 6 respectively located on both sides of the main channel 4. The first sub-channels 5 and second sub-channels 6 are alternately distributed from top to bottom. Each of the first sub-channels 5 and second sub-channels 6 has one end connected to the main channel 4. The first sub-channels 5 and second sub-channels 6 are alternately distributed from top to bottom along the length of the main channel 4. The ends of the first sub-channels 5 and second sub-channels 6 away from the main channel 4 are provided with a downward slope.

[0026] Please see Figure 3 In one embodiment, preferably, the column 1 is "L" shaped. This design is not heavy, easy to drill and fasten, and easy to remove impurities. Compared with using a solid metal block as the column 1, which is too heavy and not easy to transport, and using a hollow tube as the column 1, it is difficult to remove the rust inside the tube and is not conducive to vacuuming.

[0027] Please see Figure 3 and Figure 6In one embodiment, preferably, the column 1 has multiple through holes 1-1 for the ends of the connecting rods 2 to pass through. The number of through holes 1-1 is the same as the number of connecting rods 2, and the outer diameter of the end of the connecting rod 2 is smaller than the inner diameter of the through hole 1-1. This facilitates the end of the connecting rod 2 to pass smoothly through the through hole 1-1. Both ends of the connecting rod 2 are provided with external threads, and both ends of the connecting rod 2 are threaded with nuts 9. After the end of the connecting rod 2 passes through the through hole 1-1, the nuts 9 can be screwed onto its end. This can stably fix the position of the connecting rod 2 on the column 1, and the columns 1 can be fixed together in pairs.

[0028] Please see Figure 3-5 In one embodiment, preferably, the end face of the column 1 connected to the positioning plate 3 is provided with a limiting member. The limiting member includes two symmetrically arranged limiting blocks 1-2. The opposite end faces of the two limiting blocks 1-2 are designed to be inclined. The reserved space between the two limiting blocks 1-2 is adapted to the side of the positioning plate 3. The overall shape of the reserved space is trapezoidal. When the side of the positioning plate 3 is inserted into the reserved space, the inclined side of the trapezoid can be used to restrict the separation of the positioning plate 3 and the column 1 in the horizontal direction, thereby better forming an overall structure. The outer periphery of the column 1 is provided with an extension that contacts the end face of the limiting block 1-2 at the near end. When the positioning plate 3 is inserted into the reserved space, the bottom of the positioning plate 3 contacts the extension, and the extension supports the bottom of the positioning plate 3.

[0029] Taking a positioning plate 3 with a width of 650mm, a return plate outer diameter range of 140-170mm, and a hanging spacing of 30mm as an example, this means that the total space requirement between the return plate and adjacent components is between 170-200mm. Based on this, 3 to 4 channels can be machined on the positioning plate 3, with each channel maintaining the same spacing. The main channel 4 has a sub-channel machined every 30mm from top to bottom towards the same side, forming a shape similar to an inverted tree branch. Specifically, if the first sub-channel 5 is located on the left, then the second sub-channel 6 is located on the right, and so on, ensuring that all sub-channels on the same side have the same horizontal height and left-right spacing. The vertical height difference between each sub-channel is 30mm. To improve product versatility and ensure the structural strength of the positioning plate at high temperatures, this height difference can be adjusted to 20mm, 15mm, or even lower, thereby forming a densely distributed sub-channel on the positioning plate, similar to a densely packed tree branch layout, to achieve a wider range of application scenarios.

[0030] Three channels are machined on the positioning plate. Each channel consists of a main channel 4 and sub-channels (first sub-channel 5 and second sub-channel 6). The two ends of the hanging beam 7 are placed in the sub-channels at the same horizontal height on both sides of the positioning plate 3. Without affecting the nitriding of the return plate, the placement of the hanging beam 7 can be flexibly arranged according to the actual situation.

[0031] Uniform model return plate placement: When all return plates are of the same model, the hanging beam 7 that carries the return plate of that model can be placed in all 3 channels.

[0032] Handling a return plate with an excessively large outer diameter: If the outer diameter of the return plate is too large, one of the following two optimization methods can be selected:

[0033] Place the same type of return plate with a larger outer diameter in the passages on both sides;

[0034] Alternatively, a hanging beam 7 of the same model with a larger outer diameter is placed in the middle channel, and a hanging beam 7 of the same model with a smaller outer diameter is placed in the side channels.

[0035] By adjusting the product loading method according to the outer diameter of the return plate, not only can sufficient spacing between products be ensured, but also as many different models of products can be loaded as much as possible while ensuring quality, thereby improving space utilization and production efficiency.

[0036] The working principle and usage process of this utility model are as follows: First, insert both ends of the connecting rod 2 into the through holes 1-1 of the two columns 1 respectively, and then screw the nut 9 onto the end of the connecting rod 2 to fix the two columns 1. Next, insert the side of the positioning plate 3 into the reserved space formed by the two limiting blocks 1-2 on the column 1. When the positioning plate 3 is fully inserted, the bottom of the positioning plate 3 contacts the extension, thus forming an integral structure. Then, according to the outer diameter of the return plate, adjust the position of the hanging beam 7 in the channel to ensure that more return plates can be placed. Finally, perform ion nitriding treatment on the return plate that is carried.

[0037] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. 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.

[0038] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
