Description

Technical Field

[0001] The utility model relates to the technical field of the turntable of shot blasting machines, in particular to an adjusting device for the turntable of a shot blasting machine. Background Technique

[0002] The rotary table type shot blasting machine is mainly suitable for the production of surface cleaning of medium and small-sized workpieces. This type of equipment is suitable for engine connecting rods, gears, etc. The rotary table type shot blasting machine mainly consists of a shot blasting chamber, a turntable, a transmission mechanism, a shot feeding device, etc. During operation, the workpiece is placed on the turntable, and then the shot blasting chamber door of the rotary table type shot blasting machine is closed. The turntable is connected to the shot blasting chamber door. Under the action of the transmission mechanism, the turntable and the workpiece can be driven to rotate together. Under the action of the shot feeding device, the shot blasting material can be continuously impacted onto the surface of the workpiece, so as to effectively clean the surface of the workpiece, remove rust, oxide layers, oil stains and other contaminants. This process not only helps to improve the surface quality of the workpiece, but also enhances the adhesion of the workpiece, providing a better basis for subsequent coating or spraying processes.

[0003] However, when the turntable is running, its vibration coefficient is relatively low, and the vibration coefficient of the workpiece is also relatively low. The relatively low vibration coefficient makes the contact effect between the workpiece and the shot blasting material relatively ordinary. The impurities on the surface of the workpiece are not easy to fall quickly, and the impurities in the depressions of some workpieces with an uneven surface are not easy to be removed, which is likely to increase the processing time of the workpiece. In order to adjust the vibration coefficient of the turntable to improve the processing efficiency of the workpiece, we propose an adjusting device for the turntable of a shot blasting machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjusting device for the turntable of a shot blasting machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An adjusting device for the turntable of a shot blasting machine, including a shot blasting machine chamber door. In front of the shot blasting machine chamber door, there is an X-shaped frame. There is a transmission component between the X-shaped frame and the shot blasting machine chamber door. In the middle of the front end of the shot blasting machine chamber door, there is a guiding plate fixedly connected. The guiding plate is inclined. At the four corners of the upper end of the X-shaped frame, there are connecting columns slidably inserted. The upper ends of the four connecting columns are fixedly connected together with a turntable main body. And on the outer walls of the four connecting columns, there are spiral springs slidably sleeved. The four spiral springs are fixedly connected between the upper end of the X-shaped frame and the lower end of the turntable main body. On the outer wall of the turntable main body, there are a plurality of trapezoidal blocks fixedly connected. The inclined surface of one of the trapezoidal blocks is in contact with the outer wall of the guiding plate.

[0006] Preferably, the transmission assembly includes a housing which is fixedly installed through the inner wall of the shot blasting machine door. At the bottom end inside the housing, a driven pulley and a main pulley are respectively rotatably connected. Both the driven pulley and the main pulley pass through the upper end of the housing movably. A belt is slidably sleeved on the outer walls of the driven pulley and the main pulley.

A driving member is provided between the upper end of the main pulley and the shot blasting machine door.

[0007] Preferably, the driving member includes a fixing plate which is fixedly connected to the rear end of the shot blasting machine door.

And helical springs 10 are slidably sleeved on the outer walls of the four connecting pillars 14. The four helical springs 10 are fixedly connected between the upper end of the X-shaped frame 9 and the lower end of the turntable main body 1. A plurality of trapezoidal blocks 2 are fixedly connected to the outer wall of the turntable main body 1. The inclined surface of one of the trapezoidal blocks 2 is attached to the outer wall of the guide plate 4.

[0019] Please refer to Figure 2 And Figure 4 , in the figure, the transmission component includes a housing 7. The housing 7 is fixedly installed through the inner wall of the shot blasting machine hatch 3. And a driven pulley 13 and a main pulley 11 are respectively rotatably connected to the bottom end inside the housing 7. The driven pulley 13 and the main pulley 11 both movably penetrate through the upper end of the housing 7. And a belt 12 is slidably sleeved on the outer walls of the driven pulley 13 and the main pulley 11. And the upper end of the driven pulley 13 is fixedly connected to the center of the lower end of the X-shaped frame 9. A driving member is arranged between the upper end of the main pulley 11 and the shot blasting machine hatch 3.

[0020] Please refer to Figure 2 And Figure 4 , in the figure, the driving member includes a fixed plate 6. The fixed plate 6 is fixedly connected to the rear end of the shot blasting machine hatch 3. And a motor 5 is fixedly installed through the inner wall of the fixed plate 6. The output shaft end of the motor 5 is fixedly connected to the upper end of the main pulley 11.

[0021] Please refer to Figure 2, symmetrically fixed connection with reinforcing ribs 8 are provided between the lower ends of the housing 7 and the front and rear ends of the shot blasting machine chamber door 3 in the illustration; specifically, by providing the reinforcing ribs 8, the stability between the housing 7 and the shot blasting machine chamber door 3 is improved.

[0022] Please refer to Figure 1 and Figure 2 , in the illustration, multiple trapezoidal blocks 2 are arranged in a circular array around the center of the turntable main body 1, and the multiple trapezoidal blocks 2 and the turntable main body 1 are of an integrally formed structure; specifically, the multiple trapezoidal blocks 2 are evenly arranged, so that the vibration received by the turntable main body 1 during rotation is more uniform. At the same time, the stability of the multiple trapezoidal blocks 2 and the turntable main body 1 is good.

[0023] Please refer to Figure 2 , in the illustration, the connection relationship between the guide plate 4 and the shot blasting machine chamber door 3 is welding; specifically, the guide plate 4 can be connected to the shot blasting machine chamber door 3 by arc welding, which can provide a firm weld seam and improve the stability of the guide plate 4.

[0024] Working principle: The shot blasting machine chamber door 3 can be hinged to the shot blasting chamber of the rotary table shot blasting machine to facilitate closing the shot blasting chamber. Connect the motor 5 to an external power source, so that the motor 5 can drive the main pulley 11 to rotate, the main pulley 11 can drive the belt 12 to rotate, the belt 12 can drive the driven pulley 13 to rotate, the driven pulley 13 can drive the X-shaped frame 9 to rotate, the X-shaped frame 9 can drive multiple connecting struts 14 and multiple spiral springs 10 to rotate together, and the multiple connecting struts 14 and the multiple spiral springs 10 can drive the turntable main body 1 to rotate accordingly. Then, the workpiece placed on the upper end of the turntable main body 1 can rotate accordingly, and it is convenient to process the surface of the workpiece in cooperation with the shot feeding device of the rotary table shot blasting machine.

[0025] While the turntable main body 1 is rotating, a trapezoidal block 2 on its outer wall can slide along the outer wall of the inclined guide plate 4. The trapezoidal block 2 rotates and moves downward, which can drive the turntable main body 1 to rotate and move downward. When the turntable main body 1 moves downward, it can drive multiple connecting struts 14 to slide downward in the inner wall of the X-shaped frame 9, and the turntable main body 1 can compress multiple spiral springs 10 connected to the X-shaped frame 9. When the trapezoidal block 2 rotates away from the guide plate 4, under the action of the multiple spiral springs 10, the turntable main body 1 and the trapezoidal block 2 will move upward and reset, so that the turntable main body 1 can generate a small-amplitude vibration. As other trapezoidal blocks 2 on the outer wall of the turntable main body 1 continuously pass through the guide plate 4, the turntable main body 1 can continuously vibrate, thereby increasing the vibration coefficient of the turntable main body 1.

[0026] It should be noted that the vibration coefficient of the turntable of the turntable shot blasting machine can be adjusted to a larger value, and the vibration coefficient of the workpiece will be increased accordingly, thereby increasing the contact effect between the workpiece and the shot blasting material, and impurities on the surface of the workpiece can fall off faster. In addition, impurities in the recessed areas of some workpieces whose surfaces are not completely flat can be more easily removed, thereby reducing the processing time of the workpiece.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
