Description

Technical Field

[0001] The present application relates to the technical field of shot blasting tooling, and in particular to a front axle shot blasting tooling. Background Art

[0002] The front axle is one of the important components of the car. In order to ensure the quality and life of the front axle, shot blasting technology is often used in the production process. Shot blasting is a mechanical surface treatment technology. Through a high-speed rotating shot blaster, metal particles or quartz sand and other granular materials are sprayed onto the surface of the treated part to remove the oxide scale, oil stains and attachments on the surface, so as to improve the surface quality and enhance the adhesion. In the production of the front axle, shot blasting can effectively remove the oxide scale, rust and other impurities on the surface of the front axle, making the surface of the front axle smoother and brighter, and enhancing the adhesion between the surface of the front axle and other materials, thereby improving the wear resistance and service life of the front axle.

[0003] Traditional shot blasting mode often adopts a vertical lifting method, directly using a wire rope or an iron chain to tie one end of the workpiece and hang it in the machine tool shot blasting room. This results in the need to vertically clamp the front axle workpiece into the machine tool fixture when clamping it. Due to the complex structure of the workpiece itself, the workpiece lifting is prone to instability, easy to overturn or fall off, and cannot be clamped on the fixture, and the lifting reliability is poor; several front axle workpieces are lifted at the same time. Since the position of the shot blasting nozzle is relatively fixed, the adjacent front axle workpieces are blocked by each other, which will cause the shot blasting area to be reduced, thereby affecting the overall shot blasting effect; the length and width of the front axle directly affect the handling and stability of the entire vehicle. Therefore, the front axle will be designed and produced according to the specific model of the vehicle. In the process of shot blasting a single model of front axle, how to make the same fixture compatible with different sizes of front axles has become a problem that technicians in this field urgently need to solve. Utility Model Content

[0004] This device provides a front axle shot blasting tool. By arranging front axles with opposite inclination directions and equal numbers on both sides of the vertical plate, the overall stability of the shot blasting tool during the hoisting process is further improved. The specific implementation method is as follows:

[0005] A front axle shot blasting tool, comprising:

[0006] No less than two vertical plates arranged in parallel, the adjacent vertical plates have the same structure and opposite directions, a plurality of first mounting grooves are equidistantly provided on the side of any vertical plate along its height direction, a plurality of second mounting grooves are arranged on the opposite side thereof in a staggered manner with the first mounting grooves, and the groove length of the first mounting groove is greater than the groove length of the second mounting groove, the first mounting groove is used to support the plate seat at one end of the front axle, and the second mounting groove is used to clamp the neck at the other end of the front axle, the vertical plates on the same side are used to obliquely place a plurality of front axles, and the two sides of the vertical plates are respectively used to place the same number of front axles in opposite directions, and the same number of front axles are placed on both sides so that the tooling is in a balanced state as a whole;

[0007] The first connecting rod is arranged between the two vertical plates, and the first connecting rod is located in the upper half of the vertical plates for realizing the hoisting of the vertical plates and the front axle.

[0008] By adopting the above technical solution, two placement positions for the front axle are arranged on the front and rear sides of the vertical plate, and the inclination directions of the front axle are opposite between the two placement positions, which not only solves the problem of workpiece hoisting stability, but also solves the problem of mutual obstruction between the front axle workpieces, provides a larger and more reasonable shot blasting contact area, and further improves the shot blasting effect.

[0009] Preferably, it also includes a plurality of second connecting rods arranged between two adjacent vertical plates, the first fixing block and the second fixing block are fixedly provided on the side of the vertical plate, the second bolt passes through the second connecting rod and is threadedly connected to the first fixing block, and the first bolt passes through the first connecting rod and is threadedly connected to the second fixing block.

[0010] Preferably, a second limiting through hole is opened on the side of the vertical plate near the first fixed block, the second connecting rod is slidably connected to the second limiting through hole, and the end of the second connecting rod is opened along the length direction with a plurality of second positioning holes for the second bolt to pass through, and a first limiting through hole is opened on the side of the vertical plate near the second fixed block, the first connecting rod is slidably connected to the first limiting through hole, and the end of the first connecting rod is opened along the length direction with a plurality of first positioning holes for the first bolt to pass through.

[0011] By adopting the above technical solution, the distance between the two vertical plates is adjustable, which improves the adaptability of the tooling and allows installation of front axle workpieces of different lengths. Even if the length of the front axle workpiece remains unchanged, the inclination of the front axle workpiece can be changed by adjusting the distance, thereby adjusting it to a better shot blasting facing surface.

[0012] Preferably, the first connecting rod has two different structures to choose from, namely:

[0013] First, the middle part of the first connecting rod is set to be curved for easy lifting, and the opening side of the curved shape is vertically downward. The sides of the two adjacent vertical plates are provided with limiting through holes, and the two ends of the connecting rod are respectively slidably connected to the limiting through holes.

[0014] By adopting the above technical solution, the curved shape can improve stability during hoisting. At this time, when adjusting the spacing between the vertical plates, the side plates on both sides of the curved shape need to change the distance between them and the curved shape so that the curved structure is always in the center position during hoisting.

[0015] Secondly, the middle part of the first connecting rod is set to be straight, at least one side of the side parts of the two adjacent vertical plates is provided with a limiting through hole, and one end or both ends of the connecting rod are slidably connected to the limiting through hole.

[0016] By adopting the above technical solution, since the middle portion of the first connecting rod is set to be straight, the lifting point can be selected arbitrarily, so when adjusting the distance between the side panels, only the side panel on one side can be moved.

[0017] Preferably, the length of the first mounting groove is greater than the width at the front axle plate seat, and the length of the second mounting groove is less than the width before the front axle is necked, and greater than the width after the front axle is necked.

[0019] By adopting the above technical solution, the crimping limiter can provide lateral limit for the front axle after the front axle is placed in, so that the front axle will shake in the width direction during the lifting process. The elastic column is selected as a conventional telescopic rod with a spring structure sleeved on the outside of the telescopic rod. The spring provides the rubber pressure head with extrusion force on the front axle.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. The utility model uses the first mounting groove to support the plate seat at one end of the front axle, and the second mounting groove to clamp the neck at the other end of the front axle, so that the front axle is placed obliquely between the vertical plates, thereby increasing the effective shot blasting area of ​​the front axle;
