Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a steel shot blasting machine that facilitates the support of steel. Background Technology

[0002] Shot blasting machines are now common in factories, mainly used for surface cleaning and strengthening of metal parts. For example, the oxide scale and rust on castings and forgings after welding are cleaned by high-speed steel shot. Automotive parts and springs, which require more durability, are also strengthened by shot blasting to improve their service life. Compared with manual grinding or pickling in the past, shot blasting is much more efficient, reduces pollution, and is easier to clean up. Many machine factories, automobile factories, and shipbuilding workshops cannot do without it. It is a basic and practical piece of equipment. Currently, when shot blasting steel, the impact of steel balls can easily cause the steel to move. In roller blasting machines, the moving steel may get stuck in the rollers, affecting the operation of the machine and posing a great danger. Therefore, it is necessary to support and fix the steel. However, the device for moving the steel is difficult to disassemble, which wastes a lot of time on installation and disassembly. Utility Model Content

[0012] Reference Figures 1-7 A steel shot blasting machine for easy support of steel, comprising: The shot blasting machine body 1 has four springs 25 fixedly connected to its lower side. During operation, the shot blasting machine body 1 generates significant vibration, which is largely reduced by the four springs 25. A housing 2 is fixedly installed on the upper side of the shot blasting machine body 1, containing steel balls. A spray plate 10 is fixedly installed on the lower side of the housing 2. The steel balls inside the housing 2 are propelled out from the spray plate 10 by air pressure, impacting the steel plate surface and cleaning rust spots. A fixed plate 3 is fixedly installed inside the shot blasting machine body 1. Multiple rotating rollers 4 are rotatably connected to the side wall of the fixed plate 3. The rotating rollers 4 are capable of transmission. Two spur gears 5 are fixedly sleeved on the outer side of each of the rotating rollers 4, and adjacent spur gears 5 are connected by a gear set. The gear set includes multiple spur gears rotatably mounted on the side wall of the fixed plate 3. The second gear 22, consisting of multiple odd-numbered spur gears, allows two spur gears 5 to rotate in the same direction, with adjacent spur gears 22 meshing with each other. The outermost spur gears 22 mesh with spur gears 5 respectively. A motor 6 is fixedly installed on the side wall of the shot blasting machine body 1. The output end of the motor 6 is fixedly connected to one of the rotating rollers 4. The motor 6 drives the middle rotating roller 4 to rotate, which in turn drives the spur gears 5 and multiple spur gears 22 to rotate all the rotating rollers 4 in the same direction. A second motor 7 is fixedly installed on the side wall of the shot blasting machine body 1. A drive shaft 8 is fixedly installed on the output end of the motor 7. A cleaning roller 9 is fixedly sleeved on the outside of the drive shaft 8. Multiple sets of cleaning brushes are fixedly connected to the outside of the cleaning roller 9. The cleaning brushes can clean the steel balls sprayed onto the steel surface.

[0013] A fixed support structure is installed on the fixed plate 3. The fixed support structure includes a placement plate 13 placed on the rotating roller 4. The placement plate 13 is driven by the rotating roller 4. A bidirectional screw 14 is rotatably connected to the side wall of the placement plate 13. Two movable plates 15 are threadedly connected to the outer side of the bidirectional screw 14. The rotation of the bidirectional screw 14 can cause the two movable plates 15 to move inward or outward simultaneously. A rubber washer is provided at the rotatable connection between the bidirectional screw 14 and the placement plate 13 to prevent the bidirectional screw 14 from rotating under normal external force. The threaded connection between the screw 14 and the two movable plates 15 has a self-locking capability. Two sliding rods are slidably connected to the side walls of each of the two movable plates 15. A clamping plate 16 is fixedly connected to one end of each sliding rod. A spring 17 is fixedly connected between the two sliding rods and the movable plates 15. The movement of the movable plates 15 compresses the spring 17, causing the clamping plate 16 to enlarge, thus improving the clamping effect. A spur gear 18 is fixedly sleeved at both ends of the bidirectional screw 14. Two slide rails 11 are fixedly connected to the side wall of the fixed plate 3, one of which is fixedly connected to… There is a spur rack 19, and another spur rack 20 is fixedly connected to the side wall of the slide rail 11. Both slide rails 11 have grooves, and the spur racks 19 and 20 are respectively installed in the grooves of the two slide rails 11. The spur rack 19 is installed at the lower end of the groove of one of the slide rails 11, and is located at the front of the shot blasting machine body 1. When not being machined, it can drive the spur gear 3 18 to rotate. The spur rack 20 is installed at the upper end of the groove of the other slide rail 11, and is located at the rear of the shot blasting machine body 1. After machining, it can drive the spur gear 3 18 to rotate. The rotation direction of the second rack 20 driving the third spur gear 18 is opposite to the rotation direction of the first rack 19 driving the third spur gear 18. This allows the placement plate 13 to be clamped by the moving plate 15 during the movement process, and then released after processing. The first rack 19 and the second rack 20 have the same number of teeth, so the third spur gear 18 can perfectly mesh with the first rack 19 and the second rack 20 during the movement process. The third spur gear 18 is hidden in the groove of the slide rail 11 and will not rotate when it is not meshing with the first rack 19 and the second rack 20.

[0014] A snap-fit ​​structure is installed on the placement plate 13. The snap-fit ​​structure includes four sliders 12 that are slidably connected to the side wall of the placement plate 13. Each of the four sliders 12 is fixedly connected to the placement plate 13 by a spring 21. The four sliders 12 are in pairs, and each pair of sliders 12 is slidably sleeved with the adjacent slide rail 11. The sliders 12 are not directly connected to the slide rail 11 and can slide on the slide rail 11. A connecting rod 26 is fixedly connected between each pair of sliders 12. A baffle 23 is fixedly connected to the side wall of the shot blasting machine body 1. A pressing rod 24 is fixedly connected to the side wall of the baffle 23. The side wall of the pressing rod 24 has multiple inclined sliding surfaces. By pressing the connecting rod 26 through the pressing rod 24, the connecting rod 26 drives the slider 12 to move into the placement plate 13, thereby causing the slider 12 to disengage from the slide rail 11. At this time, as the rotating roller 4 rotates, the placement plate 13 can automatically detach from the shot blasting machine body 1.

[0015] In this invention, firstly, the operator pushes the four sliders 12 into the placement plate 13 using the connecting rod 26, so that the sliders 12 can engage with the slide rail 11. At this time, the power of the rotating roller 4 causes the placement plate 13 to move forward. During the movement of the placement plate 13, the spur gear 18 meshes with the rack 19. The spur gear 18 drives the double-acting screw 14 to rotate, causing the two moving plates 15 to move inward simultaneously. This pushes the clamping plate 16 through the spring 17. The clamping plate 16 clamps the steel and then pushes the spring 17 to push the steel. The elastic compression of spring 17 can improve the clamping effect. After the processing is completed, during the continued movement of the placement plate 13, the meshing of the spur rack 20 and the spur gear 3 18 can cause the spur gear 3 18 to drive the bidirectional screw 14 to rotate in the opposite direction. At this time, the two moving plates 15 move outward at the same time, thus releasing the clamping. When it moves to the end, the inclined surface of the extrusion rod 24 can also extrude the connecting rod 26, causing the two sliders 12 to move inward. Then, the rotation of the rotating roller 4 can cause the placement plate 13 to directly detach from the slide rail 11 without the need for manual intervention.
