[0029] In order to solve the technical problems in the background art, that is, to accurately position a workpiece 6 with discontinuous notches 7 to facilitate subsequent processing. As Figures 1-3 shown, the present application provides a technical solution: a positioning mechanism for machining the cover of a shot blasting machine, characterized as follows:

[0030] The workbench 1 serves as the basic part of the entire mechanism. Multiple mounting holes 2 are provided on the workbench 1 for passing through the power output end of the motor 8. The fixed seat 3 is arranged on the workbench 1 to support the processing table 4 and the mounting seat 12. The processing table 4 is arranged on the fixed seat 3, and a through hole 5 is provided at the center of the processing table 4 for passing through the rotating shaft 9. The motor 8 is fixedly connected to the workbench 1, and its power output end passes through the mounting hole 2 to drive the rotating shaft 9 to rotate. The rotating shaft 9 passes through the through hole 5 of the processing table 4, is connected to the motor 8 at one end, and is connected to the turntable 10 at the other end. The workpiece 6 is placed on the processing table 4 and contacts the turntable 10 internally. The rotation of the rotating shaft 9 drives the turntable 10 to drive the workpiece 6 to rotate, so as to realize the rotation of the workpiece. The ball screw 11 is arranged on the periphery of the turntable 10 and is perpendicular to the axis of the turntable 10. The mounting seat 12 is arranged on the fixed seat 3 and is internally provided with a sliding groove 13. The slider 14 is adapted to the sliding groove 13 and can slide along the sliding groove 13. One end of the slider 14 is connected to the inner wall of the sliding groove 13 through a spring 15; when the slider 14 is subjected to an external force, through the action of the spring 15, it has an outward thrust, and this thrust makes the slider 14 abut against the notch 7 of the workpiece 6, thereby realizing the positioning of the workpiece 6.

[0031] During the actual operation process, the workpiece 6 is placed on the processing table 4, and the motor 8 is used to drive the rotating shaft 9 to rotate, thereby driving the turntable 10 and the workpiece 6 to rotate. After rotating a certain angle, the slider 14 is clamped at the outer peripheral notch 7 of the workpiece 6 under the action of the spring 15, thereby realizing the precise positioning of the workpiece 6. The positioned workpiece 6 cannot rotate, while the motor 8 is still rotating. In order to prevent damage to the motor 8, by setting the ball screw 11, the rotation of the turntable 10 relative to the workpiece 6 can be realized. The top of the ball screw 11 is a ball, and an elastic device is provided inside. When the workpiece 6 cannot rotate, the ball screw 11 will slip relative to the workpiece 6, so there will be no jamming phenomenon, preventing the motor 8 from being burned out, and greatly improving the service life and reliability of the mechanism. The ball screw 11 is a commonly used part in this field, and its specific structure will not be elaborated here.

[0032] It should be noted that the ball screws 11 are evenly arranged along the circumferential direction of the turntable 10. This structural design realizes the uniform distribution of force, prevents the workpiece 6 from being deformed or displaced due to excessive local pressure during the positioning process of the workpiece 6, and thus ensures the stability of the workpiece during the processing process. The ball screws 11 can evenly abut against the workpiece 6, ensuring the stability of the workpiece 6 relative to the turntable 10, thereby greatly improving the positioning accuracy.

[0033] Furthermore, one end of the slider 14 in contact with the workpiece 6 is designed in an L shape. This structural feature enables the slider to avoid touching the edge of the workpiece 6, thereby ensuring the stability of the workpiece 6 during the positioning process. At the same time, the retreat treatment for the edge of the workpiece 6 effectively avoids the problem of affecting the processing quality due to edge wear or damage during the positioning process. Of course, to a certain extent, it also saves raw materials and costs for the enterprise.

[0034] It should be noted that the limiting grooves 16 are arranged on both sides of the sliding groove 13. The limiting grooves 16 are linear through grooves, which penetrate the side surface of the mounting seat 12, and their extending direction is parallel to the extending direction of the sliding groove 13. This structural design not only improves the movement stability of the slider 14 and the sliding groove 13, but also ensures its precise movement on the predetermined track. One end of the pin shaft 17 is fixedly connected to the slider 14, and the other end can slide along the limiting groove 16. This design further guarantees the movement range of the slider 14, prevents excessive deviation of the slider 14 during the movement process, thereby avoiding potential mechanical failures and structural damages. At the same time, this design also makes the movement of the slider 14 smoother, reduces the impact and vibration during the movement process, and extends the service life of the device. Of course, the pin shaft 17 protruding from the mounting seat 12 is also beneficial for timely adjustment of the slider 14.

[0035] Furthermore, the circular groove-shaped processing table 4 can better match the cylindrical shape of the workpiece 6. This design improves the contact accuracy during the processing process, enables the workpiece 6 to be placed more stably during the processing process, thereby effectively avoiding the processing errors caused by the unstable placement of the workpiece 6. The design of the circular groove-shaped processing table 4 is beneficial for preventing the workpiece 6 from deviating or falling due to centrifugal force during the rotation process. This improvement significantly reduces the risk of workpiece deviation or falling, improves the production efficiency, and reduces the production cost.

[0036] It should be noted that the inner diameter of the processing table 4 is adapted to the outer diameter of the workpiece 6. Specifically, the inner diameter of the processing table 4 is slightly larger than the outer diameter of the workpiece 6, generally 5 - 10 mm larger than it. In this way, when the workpiece 6 rotates under the action of the turntable 10, the processing table 4 does not hinder the rotation and can play a good protective role to prevent the workpiece 6 from rotating and falling.

[0037] It is worth noting that the inspection hole 18 is arranged on the mounting seat 12, and the inspection hole 18 penetrates the mounting seat 12; the alignment hole 19 is arranged on the slider 14 and corresponds to the inspection hole 18. The inspection hole 18 is located on the mounting seat 12, which is convenient for the operator to observe whether it is aligned with the alignment hole 19; and when the two are aligned, it indicates that the limiting of the slider 14 to the workpiece 6 is in the correct position. If the two cannot be aligned, it indicates that there is a deviation in the limiting position, and then the spring 15 needs to be adjusted or replaced.

[0038] It should be noted that the inclined plane 20 is made of wear-resistant and corrosion-resistant materials, such as stainless steel or ceramics. The inclined plane 20 can be integrally formed and cut on the slider 14, or can be fixed to the slider 14 by means of welding or threaded connection. Under the action of gravity, the workpiece 6 slides along the inclined plane 20, and at the same time, the gravity of the workpiece 6 also causes the slider 14 to retract towards the spring 15, so as to be more easily clamped into the notch 7.

[0039] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
