Description

Technical Field

[0001] This utility model relates to the field of shot blasting equipment technology, specifically to a conveying device for shaft components in a through-type shot blasting machine. Background Technology

[0002] With the development of the logistics and transportation industry, the heavy-duty truck and commercial vehicle industries are booming, leading to a year-on-year increase in demand for gearboxes. The drive shafts of gearboxes used in heavy-duty trucks and commercial vehicles are key components, with approximately a dozen drive shafts in each gearbox. Current processing techniques include forging and wedge rolling, with the process flow being sawing-forging (rolling)-heat treatment-shot blasting-finishing. Without shot blasting, the oxide scale on the shaft surface will have a fatal impact on subsequent machining accuracy, surface finish, and machine tool life. During shot blasting, the oxide scale cannot be effectively removed at the direct contact points between shafts and between the shaft and the protective sleeve, creating dead zones that are difficult to clean completely. Furthermore, shafts are cylindrical and have strong rolling properties, making direct placement on conveyor rollers unsafe.

[0003] The utility model patent with authorization announcement number CN216830357U discloses a through-type shot blasting machine shaft conveying device, including a base frame and a bracket. There are two brackets, which are arranged parallel to each other on the surface of the base frame at a certain distance. Each bracket has a number of grooves and a number of protrusions at its top. The two ends of the shaft are respectively placed on the tops of the corresponding two protrusions. There are also two handles on the surface of the base frame, which are located on both sides of the base frame. There are also four lifting lugs at the four corners of the surface of the base frame.

[0004] As shown in the above utility model, the existing shaft conveying device does not have a limiting mechanism, which makes it easy for the shaft to be misaligned and collapse when stacked in multiple layers. Moreover, the existing conveying device only limits the shaft by grooves, which is not very effective, making the shaft easy to fall off during hoisting or shot blasting. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a through-type shaft conveying device for shot blasting machines, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a through-type shot blasting machine shaft conveying device, comprising:

[0007] The base has a structure at its four corners for multi-layer stacking, and a mechanism for placing shafts is provided on both sides of the base.

[0008] The placement plate is disposed on both sides of the upper surface of the base, and the placement component is the mechanism on the base used to place the shaft component;

[0009] A limiting component is provided on the placement plate to limit the two ends of the shaft placed on the placement plate and to adjust according to the length of the shaft.

[0010] The positioning component is located in the middle of the upper surface of the base and is used to limit the middle of the shaft. The positioning component and the limiting component cooperate to stably limit the shaft on the placement plate.

[0011] Preferably, supports are fixed at the four corners of the lower surface of the base, and support rods are fixed at the four corners of the upper surface of the base. The top of the support rod has a slot that matches the support for stable stacking of multiple layers. A lifting lug is fixed on the outer side of the middle part of the support rod, and the upper ends of two adjacent support rods are connected by a handle to facilitate hoisting of the device.

[0012] Preferably, the placement plate has multiple equally spaced grooves, and rubber blocks are adhered in the grooves. The top center of the rubber blocks is set as an arc surface, and the top two ends of the rubber blocks extend to both sides of the opening of the grooves, which is used to limit and buffer the shaft.

[0013] Preferably, the limiting member includes a through groove formed below the groove, a guide sleeve is fixed to the outside of one end opening of the through groove, a protrusion is fixed below the other end opening of the through groove, and a threaded knob is threadedly connected to the middle of the protrusion.

[0014] Preferably, a limiting plate with an L-shaped structure is connected through the inside of the through groove. One end of the limiting plate is connected through the guide sleeve to improve the guiding nature of the movement of the limiting plate. A damping layer is embedded on the lower surface of the limiting plate. The damping layer corresponds to the threaded knob and is used to limit the position of the limiting plate. The other end of the limiting plate is used to limit the end of the shaft.

[0015] Preferably, the positioning element includes multiple elastic bands of different lengths fixed to the upper surface of the base. One end of each elastic band is fixed with multiple hooks that are evenly spaced. The upper surface of the base is fixed with multiple hanging rings corresponding to the elastic bands. The hanging rings are adapted to the hooks. The elastic bands and hanging rings cooperate to limit the position of the shaft. The elastic bands of different lengths are used to adapt to shafts of different diameters.

[0016] This utility model provides a through-type shaft conveying device for shot blasting machines. Compared with the prior art, it has the following advantages:

[0017] 1. This through-type shot blasting machine shaft conveying device incorporates rubber blocks, limiting components, and positioning components on a placement plate. The rubber blocks provide initial buffering and limiting for the shaft components. The limiting plate in the limiting component can be adjusted according to the shaft length. By turning the threaded knob, the limiting plate can be made to make tight contact with the end of the shaft, accurately limiting both ends of the shaft. The combination of elastic bands, hooks, and hanging rings in the positioning component allows for the selection of different lengths of elastic bands according to the shaft diameter to limit the middle of the shaft. These components work together to stably limit the shaft on the placement plate, preventing the shaft from slipping or rolling during hoisting or shot blasting. This solves the problem of existing devices relying solely on grooves and protrusions for limiting, resulting in poor limiting effect and easy shaft drop.

[0018] 2. This through-type shot blasting machine shaft conveying device features a multi-layer stacking structure at the four corners of the base. Supports are located at the four corners of the lower surface of the base, and the tops of the support rods at the four corners of the upper surface have slots that fit the supports. Lifting lugs are fixed to the outer side of the middle of the support rods, and the upper ends of adjacent support rods are connected by handles. This structural design facilitates stable multi-layer stacking of the base, overcoming the shortcomings of existing shaft conveying devices that are prone to misalignment and collapse during multi-layer stacking, thus improving the stability and safety of the device during multi-layer stacking.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides two technical solutions:

[0027] First embodiment: A through-type shot blasting machine shaft conveying device includes a base 1, a placement plate 2, a limiting member 3, and a positioning member 4. The four corners of the base 1 are provided with structures for multi-layer stacking. Both sides of the base 1 are provided with mechanisms for placing shafts. Supports 11 are fixed at the four corners of the lower surface of the base 1. Support rods 12 are fixed at the four corners of the upper surface of the base 1. The top of the support rod 12 is provided with a slot that matches the support 11 for stable multi-layer stacking. A lifting lug 13 is fixed on the outer side of the middle part of the support rod 12. The upper ends of two adjacent support rods 12 are connected by a handle 14 to facilitate the hoisting of this device.

[0028] Specifically, the placement plate 2 is set on both sides of the upper surface of the base 1. The placement component is the mechanism on the base 1 used to place the shaft. The placement plate 2 has multiple equally spaced grooves 21. Rubber blocks 22 are bonded in the grooves 21. The top center of the rubber block 22 is set as an arc surface. The top two ends of the rubber block 22 extend to both sides of the opening of the groove 21, which is used to limit and buffer the shaft.

[0029] Specifically, the limiting member 3 is set on the placement plate 2 to limit the two ends of the shaft placed on the placement plate 2 and to adjust according to the length of the shaft. The limiting member 3 includes a through groove 31 opened below the groove 21. A guide sleeve 32 is fixed to the outside of the opening at one end of the through groove 31, and a protrusion 33 is fixed below the opening at the other end of the through groove 31. A threaded knob 34 is threadedly connected to the middle of the protrusion 33. A limiting plate 35 with an L-shaped structure is connected through the inside of the through groove 31. One end of the limiting plate 35 is connected through the guide sleeve 32 to improve the guiding of the movement of the limiting plate 35. A damping layer 36 is embedded on the lower surface of the limiting plate 35. The damping layer 36 corresponds to the threaded knob 34 and is used to limit the limiting plate 35. The other end of the limiting plate 35 is used to limit the end of the shaft.

[0030] More specifically, the positioning element 4 is located in the middle of the upper surface of the base 1 to limit the middle of the shaft. The positioning element 4 cooperates with the limiting element 3 to stably limit the shaft on the placement plate 2. The positioning element 4 includes multiple elastic bands 41 of different lengths fixed to the upper surface of the base 1. One end of the elastic band 41 is fixed with multiple hooks 42 distributed at equal intervals. Multiple hanging rings 43 corresponding to the elastic bands 41 are fixed to the upper surface of the base 1. The hanging rings 43 are adapted to the hooks 42. The elastic bands 41 and the hanging rings 43 cooperate to limit the shaft. The elastic bands 41 of different lengths are used to adapt to shafts of different diameters.

[0031] When this device is in operation, the shaft is first placed between two placement plates 2, with both ends of the shaft in contact with the rubber blocks 22 on the placement plates 2. Then, according to the diameter of the shaft, the appropriate elastic band 41 is selected, and the elastic band 41 is wrapped around the shaft and connected to the corresponding hanging ring 43 through the hook 42 to limit the shaft. Next, the limiting plate 35 is moved until the limiting plate 35 contacts the end of the shaft. Then, the threaded knob 34 is turned until the threaded knob 34 contacts the damping layer 36 on the limiting plate 35, which plays a damping and limiting role, limiting the limiting plate 35. This allows the limiting plates 35 on the two placement plates 2 to cooperate in limiting both ends of the shaft, preventing the shaft from slipping or rolling during hoisting or shot blasting, thus improving the working efficiency of this device.
