Description

Technical Field

[0001] The utility model relates to the technical field of rotary table shot blasting machines, in particular to a double-station rotary table shot blasting cleaning machine. Background Art

[0002] The dual-station rotary table shot blasting machine is a surface treatment device that combines high efficiency, precision, and automation. Its dual-station design allows for seamless workpiece cleaning, significantly improving production efficiency and equipment utilization. Using a rotary table as the workpiece carrier, the machine is equipped with a highly efficient shot blaster and dust removal system, thoroughly removing scale, rust, oil, and impurities from the workpiece surface while enhancing surface hardness and fatigue resistance.

[0003] In the prior art, the working principle of the double-station rotary table shot blasting machine is based on the high-speed rotating shot blasting machine that shoots steel shots and other projectiles at high speed onto the surface of the workpiece. Through the impact and cutting action of the projectiles, the surface of the workpiece is cleaned and strengthened. In the double-station design, while one station is performing shot blasting, the other station can load and unload the workpiece, thereby achieving continuous operation and improving production efficiency. However, when driving the turntable to rotate, it is mainly driven by the motor and belt, so that the turntable rotates during shot blasting, and then drives the workpiece to rotate. However, during shot blasting, dust residue is easily left on the turntable and the workpiece. Therefore, when the staff takes out the workpiece, it takes a certain amount of time to remove the residual dust, which affects the efficiency of workpiece replacement. Utility Model Content

[0014] 1. This dual-station rotary table shot blasting machine, when shot blasting a workpiece, drives the turntable to rotate by blowing high-pressure air onto the force-bearing plate, thereby driving the workpiece to rotate. At the same time, the inclined plate guides the high-pressure airflow to directly blow away the dust at the bottom of the workpiece, preventing dust residue from remaining on the bottom of the workpiece, thereby increasing the number of work steps for the staff and reducing the efficiency of workpiece replacement.

[0015] 2. This double-station turntable shot blasting machine is equipped with an inclined plate.

The airflow will be directly sprayed onto the inclined surface of the inclined plate, thereby guiding the airflow to the filter holes through the inclined surface of the inclined plate, thereby increasing the intensity of the airflow blowing dust and thus improving the efficiency of dust cleaning;

[0016] 3. This double-station rotary table shot blasting machine, when it is necessary to drive the workpiece to rotate, starts the air pump, and the air pump will send high-pressure airflow into the annular tube through the output pipe.

[0017] 4. This double-station turntable shot blasting machine is equipped with several force-bearing plates, so that when the inclined tube sprays out high-pressure airflow, it can blow multiple force-bearing plates at the same time, thereby improving the utilization rate of the high-pressure airflow, allowing the turntable to rotate stably, and avoiding the situation where when multiple inclined tubes spray high-pressure airflow, some of the airflow blown by the inclined tubes fails to impact the force-bearing plates, resulting in a reduction in the utilization rate of the high-pressure airflow and affecting the rotation of the workpiece.

[0026] The rotating part 15 includes a connecting rod 6, an annular tube 7, an inclined tube 8 and a force plate 9. The connecting rod 6 is fixedly connected to the middle part of the top side of the support frame 3, and the bottom side of the turntable plate 4 is rotatably connected to the connecting rod 6. The annular tube 7 is fixedly connected to the middle part of the top side of the support frame 3, and the axis of the annular tube 7 and the axis of the connecting rod 6 are collinearly arranged. There are several inclined tubes 8, and several of the inclined tubes 8 are distributed in a circular array and connected to the top side of the annular tube 7. The force plate 9 is fixedly installed on the bottom side of the turntable plate 4. An air supply part 10 is provided on the side of the closed door 2 away from the support frame 3.

[0027] The airflow that is blown to the top of turntable 4 is blocked by filter 5, and the airflow that is blown to the top of turntable 4 is blocked by filter 5, and the airflow that is blown to the top of turntable 4 is blocked by filter 5. The two airflows will pass through the filter hole 5 to the top of turntable 4, thereby ensuring that the airflow can blow away the residual dust above turntable 4, so that the dust generated during the cleaning of the workpiece can be directly prevented from accumulating on the bottom side of the workpiece, eliminating the need for secondary cleaning by the staff, thereby improving the efficiency of workpiece replacement.

[0028] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the bottom side of the turntable 4 is connected to an inclined plate 11 , the top side of the inclined plate is connected to the bottom side of the turntable 4 , and the inclination angle of the inclined plate corresponds to the inclination angle of the inclined tube 8 .

[0029] In this embodiment, the inclined plate 11 is set, and when the airflow ejected from the inclined tube 8 pushes the force-bearing plate 9 to drive the turntable plate 4 to rotate, the inclined plate 11 will reach the position where the inclined tube 8 ejects the airflow, and the airflow will be directly sprayed onto the inclined surface of the inclined plate, thereby guiding the airflow to the filter hole 5 through the inclined surface of the inclined plate, thereby increasing the intensity of the airflow blowing dust, and thus improving the efficiency of dust cleaning.

[0030] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the air supply component 10 includes an air pump 12, which is fixedly connected to the side of the closed door 2 away from the support frame 3. The output end of the air pump 12 is connected to an output pipe 13, and the end of the output pipe 13 passes through the closed door 2 and is connected to the annular tube 7.

[0037] In this embodiment, since the workpiece is directly placed on the turntable disk 4 and is in direct contact with the top side of the turntable disk 4, it is easy for the workpiece to block the filter hole 5. Therefore, the support protrusion 14 is provided to support the workpiece so that a gap is left between the workpiece and the turntable disk 4, so that the airflow can be stably delivered between the workpiece and the turntable disk 4, thereby ensuring the dust cleaning effect.
