Description

Technical Field

[0001] The utility model relates to the technical field of automobile castings, in particular to a special hook type shot blasting machine for automobile castings. Background Technique

[0002] Casting is a processing technology in which metal is melted and then poured into a pre-made mold, and after condensation and cleaning, the required workpieces or blanks are obtained. Automobile casting refers to the automobile parts cast during the automobile manufacturing process. After the automobile parts are cast, they need to be polished to a certain extent. Therefore, a hook type shot blasting machine needs to be applied. The hook type shot blasting machine is divided into a single hook and a double hook. The hook type shot blasting machine uses two hooks to load workpieces and alternately enter the shot blasting and cleaning chamber. The shot blaster throws shot of 0.2 - 0.8 at the surface of the workpiece, so that the surface of the workpiece reaches a certain roughness, making the workpiece beautiful, or changing the compressive stress of the workpiece to improve its service life. This model is widely used in the surface cleaning or strengthening treatment of medium and small castings and forgings in industries such as casting, construction, chemical industry, electric motors, and machine tools. Therefore, in order to perform shot blasting and polishing on automobile castings, we need a special hook type shot blasting machine for automobile castings to assist in the completion of automobile casting work.

[0003] The defects of the special hook type shot blasting machine for automobile castings in the prior art are as follows: The patent document CN209681951U discloses a "hook type shot blasting machine, including: a box body, on which a door and a shot outlet are arranged at the upper part; a motor, which is arranged on the top of the box body; a hook, which is arranged inside the upper part of the box body, the top end of the hook is connected to the motor, and a workpiece rack is suspended at the lower end; a plurality of shot blasters, which are arranged on the box body; a first partition plate, one end of which gradually slopes downward towards the other end; a second partition plate, which is arranged below the first partition plate, and the cross-section of the second partition plate along the length direction of the upper part of the box body is >-shaped, and a plurality of first through holes are arranged at intervals on the upper part of the second partition plate, and a plurality of second through holes are arranged at intervals on the lower part; a third partition plate, which is arranged below the second partition plate, and one end of the third partition plate is fixedly connected to the middle pointed part of the second partition plate; a fourth partition plate, the top of which is fixedly connected to the other end of the third partition plate, and the bottom is located below the box body. The utility model can separate debris and shot, and can make the shot recycled."

[0004] However, although the above device can perform hook type shot blasting on objects during use, the above device cannot stably hook the objects to be shot blasted during use. At the same time, when hooking, it may require the assistance of staff to carry, which not only increases the work burden but also may pose a threat to the safety of the staff. At the same time, when the object is working inside the shot blasting machine, there is no protection on the top, so it is easy for the materials inside the device to splash to the outside. Therefore, there are still certain deficiencies in this equipment that need to be further improved. Content of the Utility Model

The output end of the first driving motor 8 is fixedly connected with a first rotating shaft 9. The first rotating shaft 9 is convenient for the winding and stretching work of a stretching chain 10 on it. A stretching chain 10 is arranged on the surface of the first rotating shaft 9. The stretching chain 10 can be retracted and extended, and thus it is convenient to hook automobile castings at different positions;

[0026] A working box 14. A working box 14 is fixedly connected to the top of the working block 5. The working box 14 is convenient for the installation of a rotating device inside. A second driving motor 15 is fixedly connected inside the working box 14. As an existing technology, the second driving motor 15 can provide power for the rotation of an automobile casting. The output end of the second driving motor 15 is fixedly connected with a second rotating shaft 16. And the bottom of the second rotating shaft 16 is fixedly connected with the top of the mechanical box 7. The second rotating shaft 16 can drive the mechanical box 7 to rotate by borrowing the force of the second driving motor 15.

[0027] As an alternative technical solution, the other end of the mechanical box 7 is fixedly connected with a rotating sleeve 11. And the other end of the first rotating shaft 9 rotates inside the rotating sleeve 11. The rotating sleeve 11 is convenient for the stable rotation of the first rotating shaft 9 inside.

[0028] As an optional technical solution, a through hole 12 is provided at the bottom of the mechanical box 7, and the extension chain 10 passes through the inside of the hole 12.

[0031] Embodiment 2:

[0032] See also Figure 1 , Figure 2 and Figure 5 The surface of the third rotating shaft 20 is fixedly connected with a closing plate 23, and the closing plate 23 is used to close the top of the box body 1 to a certain extent. A working hole 24 is opened on the top of the closing plate 23, and the working hole 24 can ensure that the closing plate 23 will not be affected by the extension chain 10 when closing.

[0033] As an optional technical solution, a protective layer 25 is fixedly connected to the inside of the box 1, and the protective layer 25 is made of rubber, so as to reduce the damage to the inner wall of the box 1 when the shot blasting machine is working. A sieve plate 26 is fixedly connected to the inside of the box 1, and a plurality of evenly distributed sieve holes are opened on the surface of the sieve plate 26.

The receiving drawer 27 can receive fallen residues and debris, thereby preventing residues from remaining inside the box 1.

[0035] Working principle: When using a hook-type shot blasting machine to work on automotive castings, first, the operator turns on the first drive motor 8, enabling the first drive motor 8 to drive the first rotating shaft 9 to rotate. As a result, the extension chain 10 wound around the surface of the first rotating shaft 9 can extend downward through the through-hole 12, causing the hook 13 to move downward. Then, the operator can grasp the hook 13 to hook the automotive casting. Subsequently, the first drive motor 8 is used again to retract the extension chain 10, which can drive the automotive casting to rise. Then, the electric telescopic rod 4 is retracted, enabling the automotive casting to be positioned above the box body 1. Then, the first drive motor 8 is used again, allowing the automotive casting to enter the interior of the box body 1. Then, the third drive motor 19 is used, enabling the third drive motor 19 to drive the third rotating shaft 20 and the closing plate 23 fixed on the surface of the third rotating shaft 20 to close towards each other. Thus, the extension chain 10 can be placed between the working holes 24, enabling a certain degree of fixed closure of the top of the box body 1. Then, the shot blaster is turned on to perform shot blasting on the automotive casting. Then, the second drive motor 15 is turned on, causing the second drive motor 15 to drive the mechanical box 7 to rotate stably within the rotating groove 6, enabling the automotive casting to rotate slowly and stably inside the box body 1. The shot blaster can perform shot blasting on it from multiple angles. Meanwhile, the debris and residues hi generated by shot blasting fall into the internal part of the lower receiving drawer 27 through the sieve plate 26, facilitating the subsequent cleaning work by the operator.
