Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a feeding mechanism of a hook shot blasting machine. Background Art

[0002] The hook shot blasting machine is a device that suspends the workpiece on a hook and cleans and treats the surface of the workpiece through the spraying and impact of shot blasting media. It is mainly used to clean and treat the surface of metal products such as castings, forgings, structural steel, stainless steel, etc., to remove surface oxide layers, rust, dirt, paint and other impurities, thereby achieving the effect of surface cleaning and increasing roughness. In addition, it can also be used for stress relief annealing treatment of welds of large welded parts, as well as sand and scale removal and removal of rust and debris from the inner walls of various pipes. The loading mechanism of the hook shot blasting machine is its important component, which is responsible for lifting the workpiece to be processed and sending it into the shot blasting chamber for cleaning.

[0003] After searching, the Chinese patent with the announcement number CN218801583U discloses a hook shot blasting machine device. Since the existing device has a fixed moving path when working, in order to ensure that all parts of the workpiece are completely processed during processing, the sandblasting time needs to be extended, which increases the cost of use. Therefore, through the cooperation between the hook, the first reduction gear and the motor, the movement of the workpiece during the shot blasting process is realized, ensuring that each position is evenly shot blasted. Compared with the traditional shot blasting method, the shot blasting efficiency is improved, and the problem that the existing device has a fixed moving path when working, in order to ensure that all parts of the workpiece are completely processed during processing, the sandblasting time needs to be extended, which increases the cost of use.

[0004] The above-mentioned hook shot blasting machine is convenient for improving the shot blasting efficiency. When using the feeding mechanism of the shot blasting machine in the prior art, a steel wire rope and a pulley are usually used to suspend the workpiece and then feed it into the shot blasting machine. Although the steel wire rope has sufficient bearing capacity, when hoisting the workpiece, the bendability of the rope body will cause the hoisted workpiece to shake left and right during transportation, resulting in instability. The workpiece is easily unhooked due to the shaking of the workpiece, and the workpiece is easily accidentally hit against an external object due to the shaking of the workpiece, causing damage to the workpiece. At the same time, the shaking of the workpiece easily increases the danger to the operator during the loading and transportation process. Utility Model Content

[0034] The loading assembly includes an installation frame 2, the installation frame 2 is fixedly connected to the upper surface of the installation plate 1, and a slide groove 3 is provided on the lower surface of the installation frame 2. A first stepper motor 4 is fixedly installed on one side of the installation frame 2, and the output end of the first stepper motor 4 is fixedly connected to the first screw rod 5, the external thread of the first screw rod 5 is connected to the moving block 6, and the outside of the moving block 6 is fixedly connected to the connecting frame 7. The upper surface of the connecting frame 7 is fixedly installed with a second stepper motor 8, and the output end of the second stepper motor 8 is fixedly connected to the second screw rod 9. The interior of the connecting frame 7 is fixedly connected to a fixing rod 10, and the external thread of the second screw rod 9 is connected to a mounting bracket 11. The mounting bracket 11 is slidably connected to the outside of the fixing rod 10, and the lower surface of the mounting bracket 11 is fixedly connected to a mounting box 12. A hook body 13 is provided below the mounting box 12. The slide groove 3 facilitates the sliding of the moving block 6, which improves the stability of the moving block 6 when moving. The first screw rod 5 is convenient for driving the moving block 6 to move, and the second screw rod 9 is convenient for driving the position of the hook body 13 to move, and the mounting box 12 is convenient for installing the mounting block 22 through the mounting groove 14.

[0035] As attached Figure 6 As shown, the upper surface of the mounting box 12 is fixedly connected with a fixing frame 15, the interior of the fixing frame 15 is fixedly connected with a fixing column 16, the interior of the fixing frame 15 is rotatably connected with a stud 17, the external threaded connection of the stud 17 is connected with a limiting block 18, the limiting block 18 is slidably connected to the outside of the fixing column 16, the fixing column 16 plays a role in limiting and stabilizing the movement of the limiting block 18, and the limiting block 18 facilitates limiting the mounting block 22.

[0036] As attached Figure 7 As shown, a second bevel gear 20 is rotatably connected to one side of the inner wall of the fixed frame 15, and one end of the stud 17 is fixedly connected to the first bevel gear 19. The first bevel gear 19 and the second bevel gear 20 are meshed together. The cross-section of the limit block 18 is set to be T-shaped, and the middle part of the second bevel gear 20 is fixedly connected to the knob 21 through the shaft. The meshing of the first bevel gear 19 and the second bevel gear 20 makes it easy to turn the knob 21 to drive the stud 17 to rotate.

[0037] As attached Figure 5 As shown, the upper surface of the hook body 13 is fixedly connected to a mounting block 22 , and a limiting groove 23 is provided on the upper surface of the mounting block 22 . The mounting block 22 is conveniently installed into the interior of the mounting box 12 , and the limiting groove 23 is convenient for snapping into the limiting block 18 .

[0038] Working principle: When in use, first install the mounting plate 1 on the top of the shot blasting machine, and then turn on the second stepper motor 8. The second stepper motor 8 drives the second screw rod 9 to rotate, so that the second screw rod 9 drives the mounting frame 11 to move downward, so that the mounting frame 11 indirectly drives the hook body 13 to move downward through the mounting box 12, and the workpiece to be suspended is hung on the hook body 13. The second stepper motor 8 is turned on to reverse, so as to drive the second screw rod 9 to rotate in the opposite direction, thereby facilitating the suspended workpiece to rise, and then the first stepper motor 4 is turned on, so that the first stepper motor 4 drives the first screw rod 5 to rotate, so that the first screw rod 5 drives the moving block 6 to move inside the mounting frame 2 under the limit of the moving block 6 by the mounting frame 2, thereby facilitating the transport of the workpiece into the shot blasting machine, facilitating the processing of the workpiece, and helping to improve the stability of the loading mechanism when suspending the workpiece for loading;

[0039] When the hook body 13 needs to be disassembled for replacement, the knob 21 is turned, and the second bevel gear 20 is driven to rotate by the knob 21. The engagement of the second bevel gear 20 with the first bevel gear 19 drives the first bevel gear 19 to rotate, thereby driving the stud 17 to rotate. When the stud 17 rotates, the limit block 18 is driven to move upward, so that the limit block 18 is disengaged from the inside of the limit groove 23. Then, the hook body 13 is held and the mounting block 22 is slid out of the inside of the mounting box 12, thereby facilitating the disassembly of the hook body 13 and helping to replace the hook body 13 in time. The operation is reversed during installation, which improves the safety when replacing the hook body 13.
