Abstract
Description
Technical Field
[0001] The present application relates to the field of pallets for parts processing, and in particular to a mesh frame pallet for heat treatment of shaft parts. Background Art
[0002] In the field of hot processing of parts, pallets are usually used to hold a large number of parts. Users can move a large number of parts by moving pallets, thereby improving the efficiency of part processing. During the hot processing of shaft parts, when the shaft parts are heated, they are prone to deformation, resulting in poor processing quality of the shaft parts. In order to reduce the radial stress on the shaft parts, it is usually necessary to place the shaft parts vertically in the heat treatment equipment for processing, thereby reducing the probability of the shaft parts' own weight exerting stress on the shaft parts and causing deformation of the shaft parts.
[0003] The relevant shaft heat treatment tray is made of materials with good heat resistance. There are multiple blind holes vertically opened on the tray. The shaft can be kept in a vertical state by vertically inserting the shaft into the blind holes of the tray. The user can place a large number of shafts into the heat treatment equipment by moving the tray, thereby improving work efficiency.
[0004] The above-mentioned related technical solutions have the following defects: after the blind holes are opened on the pallet, the pallet can only be used to place shafts of fixed sizes. Processing shafts of different sizes requires manufacturing multiple pallets, which causes inconvenience. Utility Model Content
[0005] In order to facilitate users to place shafts of different sizes in a tray for processing, the present application provides a mesh frame tray for heat treatment of shafts.
[0006] The present application provides a mesh frame tray for heat treatment of shaft parts, which adopts the following technical solution:
[0007] A mesh frame tray for heat treatment of shaft parts comprises a tray and a mesh frame, wherein the tray and the mesh frame are detachably connected, the mesh frame is arranged on one side surface of the tray, a plurality of through holes are opened on the mesh frame, and the length direction of the through holes is parallel to the thickness direction of the mesh frame.
[0008] By adopting the above technical solution, the screen frame is detachably connected to the pallet, and a through hole is opened on the screen frame, so that the shaft can be vertically inserted into the through hole of the screen frame, and the bottom of the shaft abuts against the pallet, so that a large number of shafts can be vertically arranged on the pallet. The user can adjust the size of the through hole on the screen frame by replacing screen frames of different sizes on the pallet, so that shafts of different sizes can all be inserted into the through holes of the screen frame, and thus shafts of different sizes can all be vertically arranged on the pallet, which is convenient for processing.
[0009] Optionally, the tray includes a frame and a fine wire mesh, the frame is a frame-type structure, and the fine wire mesh is laid flat in the frame and connected to the frame.
[0010] By adopting the above technical solution, a fine wire mesh is arranged in the frame so that the fine wire mesh abuts against and supports the bottom of the shaft. When the shaft is located in a heat treatment device for heat treatment, the contact area between the bottom of the shaft and the fine wire mesh is small, thereby improving the heat exchange efficiency between the bottom of the shaft and the high-temperature gas in the heat treatment device, reducing the temperature difference between the two ends of the shaft, and improving the processing quality of the shaft heat treatment.

[0012] By adopting the above technical solution, a limiting sleeve is provided on the frame so that the limiting sleeve can clamp the screen frame through the clamping groove, thereby keeping the screen frame in a stable position on the pallet.

[0014] By adopting the above technical solution and using coarse wire mesh to make the mesh frame, the overall weight of the mesh frame can be reduced, making it easier for users to move the pallet. When the shaft is vertically inserted into the mesh frame and heat treated, the side wall of the shaft can exchange heat with the high-temperature gas in the heat treatment equipment, so that the shaft is evenly heated as a whole during the heat treatment process, thereby improving the processing quality.

[0023] In summary, the beneficial technical effects of this application are:
[0024] 1. The screen frame is detachably connected to the pallet, and a through hole is opened on the screen frame, so that the shaft can be vertically inserted into the through hole of the screen frame, and the bottom of the shaft abuts on the pallet, so that a large number of shafts can be vertically arranged on the pallet.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.
[0034] The present application embodiment discloses a mesh frame tray for heat treatment of shaft parts, referring to Figure 1 , Figure 2 and Figure 3 , including a tray 3 and a screen frame 4, the tray 3 and the screen frame 4 are detachably connected, and the screen frame 4 is arranged above the tray 3. The screen frame 4 is provided with a plurality of through holes, and the shafts to be processed can be inserted into the through holes of the screen frame 4, and the tray 3 supports the bottom of the shafts, so that the plurality of shafts can be vertically arranged on the tray 3. The user places the tray 3 into the heat treatment equipment, so that the plurality of shafts on the tray 3 can be subjected to the surface heat treatment process, which is convenient for the user to move a large number of shafts and improves the efficiency of shaft processing.
[0035] Reference Figure 2 The tray 3 includes a frame 31, a plurality of limiting sleeves 32 and a fine wire mesh 33. The frame 31 is set as a rectangular frame. The fine wire mesh 33 is laid flat in the frame 31. Four limiting sleeves 32 are set. The limiting sleeves 32 are fixedly connected at the corners of the frame 31. The limiting sleeves 32 are perpendicular to the frame 31. When the shaft is inserted into the through hole of the mesh frame 4, the end of the shaft abuts against the fine wire mesh 33. When the shaft is heat-treated in the heat processing equipment, the end of the shaft can be fully heated, thereby improving the processing quality of the shaft.
[0036] Reference Figure 3The mesh frame 4 includes a plurality of coarse wire meshes 41 and a plurality of brackets 42. In this embodiment, two coarse wire meshes 41 are provided. The two coarse wire meshes 41 are laid flat and arranged parallel to each other. The mesh positions of the two coarse wire meshes 41 correspond to each other. The mesh size of the coarse wire mesh 41 is larger than the mesh size of the fine wire mesh 33. A plurality of brackets 42 are arranged between the coarse wire meshes 41, so that the mesh frame 4 has structural strength as a whole. The mesh frame 4 is detachably connected to the tray 3. The user inserts the shaft into the mesh frame 4 vertically so that the two ends of the shaft are stuck in the mesh of the coarse wire mesh 41, and the bottom of the shaft abuts against the fine wire mesh 33. When the shaft is processed in the heat treatment equipment, the shaft size can be kept in a vertical state in the coarse wire mesh 41 after being heated and changed, and the radial stress on the shaft is small, so that the dimensional accuracy of the shaft after heat treatment is high.
[0037] Reference Figure 2 and Figure 3 The edge of the screen frame 4 is provided with a slot 43, which is an arc-surface slot and fits the surface of the stop sleeve 32. The user puts the screen frame 4 vertically on the tray 3, so that the multiple stop sleeves 32 on the tray 3 fit into the slot 43 one by one, and then the screen frame 4 can be conveniently and quickly fixed on the tray 3. By replacing the screen frame 4 on the tray 3, the user can insert shafts of different sizes into the screen frame 4 and perform heat treatment.
[0038] Reference Figure 1 and Figure 4 The tray 3 is detachably connected to the base frame 1, which is a rectangular frame, and the corners of the base frame 1 are fixed with positioning columns 2, which are vertically arranged, and the limiting sleeve 32 is a hollow round tube. The limiting sleeve 32 can be sleeved on the positioning column 2. The user sets multiple trays 3 on the positioning column 2, so that the multiple trays 3 are stacked in layers in the vertical direction, and can move a large number of shafts by moving the base frame 1, thereby further improving the efficiency of the hot processing of the shafts.
[0039] Reference Figure 5 , the diameter of the positioning column 2 is smaller than the inner diameter of the limiting sleeve 32. When the limiting sleeve 32 is sleeved on the positioning column 2, the limiting sleeve 32 and the positioning column 2 are loosely matched. When the base frame 1 and the tray 3 are placed in the heat treatment equipment and subjected to heat treatment, the positioning column 2 and the limiting sleeve 32 are easily expanded by heat, making it difficult to remove the tray 3 from the positioning column 2, affecting the work efficiency. By making the positioning column 2 and the limiting sleeve 32 loosely matched, space for expansion is reserved for the positioning column 2 and the limiting sleeve 32, so that the tray 3 can be quickly removed from the positioning column 2 after heat treatment and subjected to subsequent processing.
[0040] The implementation principle of the embodiment of the present application is as follows: by arranging a mesh frame 4 on the tray 3, the mesh frame 4 plays a limiting role on the shaft. When the shaft is placed in the heat treatment equipment, the shaft remains in a vertical state, reducing the probability of radial stress on the shaft, thereby reducing the probability of bending of the shaft, and making the dimensional accuracy of the shaft after processing higher. By using a coarse wire mesh 41 to support the shaft, the contact area between the shaft and the tray 3 and the mesh frame 4 is reduced. When the shaft is located in the heat treatment equipment, the shaft is heated evenly, further improving the quality of heat treatment.
[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
