Description

Technical Field

[0001] This utility model relates to a shot blasting cage that can be used for both rod-type and disc-type half-shafts, belonging to the field of half-shaft shot blasting equipment. Background Technology

[0002] With the rapid development of the automotive industry, the production efficiency and quality requirements of automotive parts are constantly increasing. The half-shaft is a crucial component in automotive production, its function being to transmit torque from the differential to the wheels, thereby enabling the wheels to drive the vehicle. It is an essential part of the automotive transmission system. Automotive half-shafts are mainly divided into disc half-shafts and rod half-shafts in terms of their external structure, both of which are widely used. Both disc and rod half-shafts require surface induction hardening during production. After hardening, an oxide scale will form on the surface. Therefore, after low-temperature tempering, automotive half-shafts need to undergo precision shot blasting to remove the surface oxide scale, relieving hardening stress while ensuring the appearance quality of the finished product. Thus, shot blasting is a very important process in the manufacturing of automotive half-shafts, and a shot blasting cage is required for hoisting the half-shafts during shot blasting.

[0003] For example, the shot blasting machine tooling device for automated loading and unloading of rod-type half-shafts disclosed in patent announcement number CN218613529U can only lift rod-type half-shafts; similarly, the shot blasting machine tooling device for automated loading and unloading of disc-type half-shafts disclosed in patent announcement number CN218658496U can only lift disc-type half-shafts. The shot blasting cage structures in the above-mentioned prior art have relatively limited functionality, typically only capable of lifting one type of automotive half-shaft, thus limiting their application. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a shot blasting cage that integrates the hoisting functions of rod-type half shaft and disc-type half shaft.

[0005] The shot blasting cage of this utility model, which can be used as both a rod-type and a disc-type half-shaft, includes a central shaft. An upper indexing plate and a lower indexing plate are fixedly connected to the central shaft. Multiple clamping mechanisms are fixedly connected to the upper indexing plate, and multiple support mechanisms are fixedly connected to the lower indexing plate. Each clamping mechanism corresponds to one support mechanism. Each clamping mechanism includes a clamping plate fixedly connected to the upper indexing plate. A guide sleeve is fixedly connected to the bottom of the clamping plate. A guide hole is provided in the guide sleeve, and an upper ejector pin is slidably connected through the guide hole. An ejector pin limiting structure is connected between the guide sleeve and the upper ejector pin. A spring is placed between the upper ejector pin and the clamping plate. Each support mechanism includes a support plate fixedly connected to the lower indexing plate. A support seat is provided on the support plate, and a lower ejector pin is fixedly connected to the support seat.

[0006] Furthermore, the ejector pin limiting structure includes a limiting hole provided on the guide sleeve and a limiting platform provided on the upper ejector pin. The limiting platform is slidably connected to the guide hole, and the diameter of the limiting platform is larger than the diameter of the limiting hole.

[0007] Furthermore, the clamping plate has multiple first upper mounting holes, and the upper indexing plate has second upper mounting holes that correspond one-to-one with the first upper mounting holes.

[0008] Furthermore, the upper indexing plate has multiple positioning holes, the diameter of which is larger than the outer diameter of the guide sleeve.

[0009] Furthermore, the support plate has multiple first lower mounting holes, and the lower indexing plate has second lower mounting holes that correspond one-to-one with the first lower mounting holes.

[0010] Furthermore, the support base is provided with a threaded hole, and the lower ejector pin is threaded into the threaded hole.

[0011] Furthermore, the clamping plate and the guide sleeve are fixedly connected by multiple bolts.

[0012] Furthermore, the bolts are hexagon socket head cap screws, and the clamping plate has grooves that correspond one-to-one with the hexagon socket head cap screws.

[0013] Working principle and process:

[0014] When hoisting a rod-type half-shaft, first align the reference hole at one end of the rod-type half-shaft with the upper ejector pin. Then, apply an upward force to the rod-type half-shaft, causing the upper ejector pin to compress the spring and move upward. Next, align the reference hole at the other end of the rod-type half-shaft with the lower ejector pin. Then, slowly release the force. Under the restoring action of the spring, the upper ejector pin moves downward, thereby pressing the rod-type half-shaft firmly onto the support seat. The lower and upper ejector pins can radially position the rod-type half-shaft, preventing it from radially displacing and falling off. When hoisting a disc-type half-shaft, ... With the flange end of the disc half-shaft facing downwards, align the upper reference hole of the disc half-shaft with the upper ejector pin, and then apply an upward force to the disc half-shaft. Similar to the hoisting process of the rod half-shaft, the upper ejector pin can press the disc half-shaft onto the support seat. The lower and upper ejector pins can position the disc half-shaft radially, and the support plate can provide auxiliary radial positioning of the disc half-shaft to prevent radial displacement and detachment. After all rod half-shafts or disc half-shafts have been hoisted, subsequent shot blasting operations can be carried out.

[0015] The advantages of this utility model compared with the prior art are:

[0016] The shot blasting cage of this invention, which can be used for both rod-type and disc-type half-shafts, is suitable for hoisting both rod-type and disc-type half-shafts, and has good applicability. Attached Figure Description

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0028] Example 1:

[0029] like Figures 1 to 5As shown, the shot blasting cage of this utility model, which combines rod-type and disc-type half-shafts, includes a central shaft 3. An upper indexing plate 6 and a lower indexing plate 1 are fixedly connected to the central shaft 3. Multiple pressing mechanisms are fixedly connected to the upper indexing plate 6, and multiple support mechanisms are fixedly connected to the lower indexing plate 1. Each pressing mechanism corresponds to one support mechanism. The pressing mechanism includes a pressing plate 12 fixedly connected to the upper indexing plate 6. A guide sleeve 16 is fixedly connected to the bottom of the pressing plate 12. A guide hole 19 is provided in the guide sleeve 16. An upper ejector pin 17 is slidably connected through the guide hole 19 and passes through the guide sleeve 16. An ejector pin limiting structure is connected between the guide sleeve 16 and the upper ejector pin 17. A spring 20 is placed between the upper ejector pin 17 and the pressing plate 12. The support mechanism includes a support plate 8 fixedly connected to the lower indexing plate 1. A support seat 9 is provided on the support plate 8, and a lower ejector pin 10 is fixedly connected to the support seat 9.

[0030] like Figures 6 to 9 As shown, when hoisting the rod-type half-shaft 22, first align the reference hole at one end of the rod-type half-shaft 22 with the upper ejector pin 17, then apply an upward force to the rod-type half-shaft 22, causing the upper ejector pin 17 to compress the spring 20 and move upward. Then align the reference hole at the other end of the rod-type half-shaft 22 with the lower ejector pin 10, and then slowly release the force. Under the restoring action of the spring 20, the upper ejector pin 17 moves downward, thereby pressing the rod-type half-shaft 22 tightly onto the support seat 9. The lower ejector pin 10 and the upper ejector pin 17 can radially position the rod-type half-shaft 22, preventing the rod-type half-shaft 22 from radially displacing and falling off; hoisting the disc-type half-shaft 23 When installing the disc half-shaft 23, with the flange end facing down, align the upper reference hole of the disc half-shaft 23 with the upper ejector pin 17, and then apply an upward force to the disc half-shaft 23. Similar to the hoisting process of the rod half-shaft 22, the upper ejector pin 17 can press the disc half-shaft 23 onto the support seat 9. The lower ejector pin 10 and the upper ejector pin 17 can position the disc half-shaft 23 radially, and the support plate 8 can provide auxiliary radial positioning for the disc half-shaft 23 to prevent the disc half-shaft 23 from displacing and falling off. After all the rod half-shafts 22 or disc half-shafts 23 have been hoisted one by one, the subsequent shot blasting operation can be carried out.

[0031] Example 2:

[0032] like Figures 1 to 9 As shown, based on Example 1,

[0033] Furthermore, the ejector pin limiting structure includes a limiting hole 21 on the guide sleeve 16 and a limiting platform 18 on the upper ejector pin 17. The limiting platform 18 is slidably connected to the guide hole 19, and the diameter of the limiting platform 18 is larger than the diameter of the limiting hole 21. The relative sliding between the upper ejector pin 17 and the guide sleeve 16 is achieved through the sliding cooperation between the limiting platform 18 and the guide hole 19, resulting in a simple structure and stable operation. The limiting hole 21 limits the limiting platform 18, preventing the upper ejector pin 17 from falling out of the guide sleeve 16.

[0034] Furthermore, the clamping plate 12 has multiple first upper mounting holes 13, and the upper indexing plate 6 has second upper mounting holes 4 corresponding to the first upper mounting holes 13. Through the first upper mounting holes 13 and the second upper mounting holes 4, the upper indexing plate 6 and the clamping plate 12 can be fixedly connected by bolts, making the installation and disassembly of the clamping plate 12 more convenient.

[0035] Furthermore, the upper indexing plate 6 has multiple positioning holes 5 extending through it, the diameter of which is larger than the outer diameter of the guide sleeve 16. This allows the guide sleeve 16 to be inserted into the positioning holes 5, facilitating the installation of the pressure plate 12.

[0036] Furthermore, the support plate 8 has multiple first lower mounting holes 7, and the lower indexing plate 1 has second lower mounting holes 2 that correspond one-to-one with the first lower mounting holes 7.

[0037] Furthermore, the support base 9 is provided with a threaded hole 11, and the lower ejector pin 10 is threaded into the threaded hole 11. By rotating the lower ejector pin 10, the lower ejector pin 10 can be installed and removed, thereby facilitating the maintenance or replacement of the lower ejector pin 10.

[0038] Furthermore, the clamping plate 12 and the guide sleeve 16 are fixedly connected by multiple bolts, which allows the clamping plate 12 and the guide sleeve 16 to be disassembled and separated, thereby facilitating the maintenance and replacement of the spring 20 and the upper ejector pin 17.

[0039] Furthermore, the bolt is a hex socket head cap screw 14, and the clamping plate 12 is provided with grooves 15 corresponding to the hex socket head cap screws 14. The head of the hex socket head cap screw 14 can be hidden in the groove 15, thus not occupying the external space of the clamping plate 12.
