Description

Technical Field

[0001] The utility model relates to the technical field of shot peening treatment for variable-speed cams, and particularly relates to a shot peening treatment device for machining variable-speed cams. Background Technique

[0002] Shot peening treatment technology is a process method that uses high-speed moving shot materials (such as steel shots, steel sands, etc.) to impact and rub the surface of workpieces to achieve the effects of cleaning, strengthening, and beautifying the surface. This technology projects the shot materials onto the surface of workpieces through a high-speed rotating shot peening machine, removes impurities such as oxide layers, rust, and old coatings, and at the same time increases the surface roughness and improves the coating adhesion.

[0003] A variable-speed cam is a mechanical component that can work at different speeds. It needs to have characteristics such as high strength, high wear resistance, high temperature resistance, fatigue resistance, and corrosion resistance. During the production process of cams, shot peening is used to process the surface of the cams to improve the strength of the cams and remove impurities on the surface of the cams.

[0004] Traditional shot peening equipment can only process items with surface contact shot peening. When machining variable-speed cams, since the cams need to be processed quickly and in large quantities, the shot materials ejected by traditional shot peening equipment cannot contact the variable-speed cams at the bottom, resulting in problems such as low machining quality and slow machining speed of variable-speed cams. Therefore, it is urgent to design a shot peening treatment device for machining variable-speed cams to solve the above problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a shot peening treatment device for machining variable-speed cams. Inside the treatment box, there is a vibrating cam holder and a cam tumbling basket. During the shot peening treatment process of the cams, through the repeatedly vibrating cam tumbling basket, a large number of cams can be continuously tumbled and moved upwards, so that the shot materials ejected from the upper part of the treatment box can fully contact the cams, thereby improving the machining quality of the variable-speed cams. At the same time, through the fast tumbling method, the machining efficiency of the variable-speed cams can be improved while ensuring high-quality machining.

[0006] The shot peening treatment device for machining variable-speed cams provided by the utility model:

[0007] It includes a treatment box. Above the treatment box, there is a connected shot peening box. Inside the shot peening box, there is a rotatably connected shot peening impeller. The upper inner side of the treatment box is vibrationally connected with a cam holder. The cam holder is limited to reciprocally slide on both sides inside the treatment box. At both sides of the bottom of the cam holder, there are symmetrically hinged cam tumbling baskets. The cam tumbling baskets are magnetically adsorbed to each other. Inside the walls of the cam tumbling baskets, there are fixed tumbling stoppers.

[0008] Preferably, a vibration motor is fixed to one side of the outer wall of the position where the processing box is connected to the cam retaining frame, and the output end of the vibration motor is connected to a driving cam. A transmission rod is hinged on one side of the top of the driving cam, and the other end of the transmission rod is hinged to the middle of the outer wall of the cam retaining frame. The vibration motor rotates through the driving cam connected to the output end, which can drive the transmission rod to slide back and forth on the inside of the processing box, and reciprocately pulls the cam retaining frame that is slidingly connected to the inside of the processing box, thereby realizing the vibration of the cam retaining frame.

[0009] Preferably, sealing electromagnetic blocks that abut and fit together are fixed on both sides of the bottom surface of the cam rolling basket, and an inclined cam baffle is fixed on the middle part of the lower part of the processing box. A discharge port is opened on one side of the bottom of the cam baffle, and a shot blasting discharge seat is fixed on the bottom of the inner side of the processing box, and a shot blasting outlet is opened at the bottom of the shot blasting discharge seat. The setting of the sealing electromagnetic block can adsorb and connect the bottom of the cam rolling basket. When discharging is required, it is only necessary to close the sealing electromagnetic block to complete the opening of the cam rolling basket. At the same time, the outside of the sealing electromagnetic block is coated with a sealing layer to prevent the electromagnetic block from adsorbing the speed change cam. The cam baffle can use its own inclined structure to send the cam inside the cam rolling basket to the outside. In the process of cam processing, the shot material will fall into the shot blasting discharge seat at the bottom of the processing box through the holes of the cam rolling basket and the cam baffle, and roll to the outside of the processing box through the inclined structure of the shot blasting discharge seat itself, which is convenient for repeated use.

[0010] Preferably, the shot blasting impeller includes a shot blasting charging bin opened at the center, a shot outlet is opened on the circumference of the outer surface of the shot blasting impeller, and annular shot blasting blades equidistantly distributed are fixed on the outer wall of the shot blasting impeller between the shot outlets. The shot inside the shot blasting box enters through a shot blasting tube on one side of the shot blasting box, and then enters the shot blasting charging bin inside the shot blasting impeller. As the shot blasting charging bin rotates, the shot moves through the shot outlet to the surface of the shot blasting blade. As the shot blasting blade rotates at a high speed, the shot is thrown downward, so that the shot processes the speed change cam.

[0011] Preferably, bearings are sleeved on both ends of the outer wall of the shot blasting impeller, and the bearings are embedded and fixed in the inner wall of the shot blasting box. A driving motor is fixed on one side of the outer wall of the shot blasting box, and the output end of the driving motor is transmission-connected to the shot blasting impeller. The bearings can improve the rotation stability of the connection between the shot blasting impeller and the shot blasting box and reduce friction. The driving motor can provide a driving force for the rotation of the shot blasting impeller.

[0012] Preferably, a feed port is provided on the top surface of the processing box on one side of the shot blasting box, and a sealing cover is hinged on the inner side of the feed port. The feed port is provided on the top of the processing box to facilitate feeding of the variable speed cam, and the sealing cover inside the feed port can ensure that the device does not eject the shot during operation, thereby improving the safety of the equipment.

[0014] 1. The present utility model can perform reciprocating vibration and tumbling on the variable-speed cams during the machining process, enabling a large number of stacked variable-speed cams to come into full contact with the shot material, thereby improving the machining quality of the variable-speed cams. At the same time, all the variable-speed cams can continuously tumble and move upward, which can improve the machining efficiency of the variable-speed cams. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0022] Please refer to the attached Figures 1-4 , a shot blasting treatment device for variable-speed cam machining provided by an embodiment of the present utility model, the shot blasting treatment device for variable-speed cam machining includes:

[0023] Processing box 1, a shot blasting box 2 is fixed at the center of the top surface of the processing box 1. The bottom surface of the shot blasting box 2 is connected to the processing box 1. An inlet 20 is provided on one side of the shot blasting box 2. A sealing cover is hinged inside the discharge port 13. The sealing cover can seal the inside of the processing box 1, improving the safety during the internal working process of the processing box 1.

[0024] Inside the shot blasting box 2, a shot blasting impeller 3 is rotatably connected. Bearings 18 are sleeved at both ends of the shot blasting impeller 3 and are rotatably connected to the shot blasting box 2, which can avoid friction between the shot blasting impeller 3 and the shot blasting box 2 and improve the sliding effect. On one side of the outer wall of the shot blasting box 2, a driving motor 19 is connected. The driving motor 19 provides the driving force for the rotation of the shot blasting impeller 3.

[0025] During the working process of the shot blasting impeller 3, the shot material will be sent into the shot blasting injection bin 15 at the center of the shot blasting impeller 3 through the shot inlet pipe connected to one side of the outer wall of the shot blasting box 2. Then, with the rotation of the shot blasting impeller 3, the shot material will move to the surface of the shot blasting blades 17 through the shot outlet 16. With the high-speed rotation of the shot blasting blades 17, the shot material will be thrown at high speed towards the inside of the processing box 1.

[0026] A cam stopper 4 is connected in a limited sliding manner at the upper part inside the processing box 1. One side of the cam stopper 4 is hinged with a transmission rod 9. A vibration motor 7 is fixed at the position on the outer wall of the processing box 1 close to the cam stopper 4. A driving cam 8 is fixed at the output end of the vibration motor 7. And one end of the transmission rod 9 away from the cam stopper 4 is hinged to one side of the top of the driving cam 8. With the drive of the vibration motor 7, the driving cam 8 will drive the transmission rod 9 to reciprocally pull the cam stopper 4 to slide inside the processing box 1, making the cam stopper 4 vibrate.

[0027] On both sides of the bottom surface of the cam stopper 4, symmetrically fitting cam tumbling baskets 5 are hinged. At the bottom end of the fitting position of the cam tumbling baskets 5, a sealing electromagnetic block 10 that abuts and fits is fixed. Tumbling stoppers 6 are fixed on the inner wall of the cam tumbling baskets 5. When the cam stopper 4 drives the cam tumbling baskets 5 to vibrate, the tumbling stoppers 6 will unidirectionally limit the cams at the bottom of the cam tumbling baskets 5 and gradually tumble the cams to both sides during the vibration process. And the cams that have undergone shot material processing at the top of the cam tumbling baskets 5 will be squeezed towards the middle by the cams on both sides and gradually move to the bottom of the cam tumbling baskets 5, circulating the tumbling movement of the cams, so as to achieve the rapid processing and high-quality treatment of variable-speed cams.

[0028] When the processing of the variable-speed cam is completed, the power of the sealing electromagnetic block 10 is turned off, and the cam tumbling baskets 5 will open to both sides, sending the variable-speed cams downward to complete the collection of the variable-speed cams.

[0029] In the middle of the lower part inside the processing box 1, a cam baffle 11 is connected. The cam baffle 11 is designed to be inclined. At the position where the bottom of the cam baffle 11 is connected to the processing box 1, a discharge port 13 is provided. After the variable-speed cam discharged from the cam tumbling basket 5 falls on the surface of the cam baffle 11, it slides to the outside of the discharge port 13 through the inclined angle of the cam baffle 11.

[0030] At the bottom of the processing box 1, a shot blasting discharge seat 12 is provided. The shot blasting discharge seat 12 itself is designed with a triangular inclined structure. At the position where its bottom end is connected to the processing box 1, a shot blasting outlet 14 is provided. The shot material after being thrown by the shot blasting impeller 3 to impact the cam will fall onto the top surface of the cam baffle 11 through the cam tumbling basket 5. Through the holes provided inside the cam baffle 11, the shot material will fall onto the top surface of the shot blasting discharge seat 12 and then roll to the position of the shot blasting outlet 14.

[0031] Usage process:

[0032] Put the variable-speed cam into the feeding port 20, and then start the vibration motor 7 and the drive motor 19. Throw the shot material through the shot blasting impeller 3 to the inside of the cam tumbling basket 5 to process the variable-speed cam during vibration. The used shot material will fall to the bottom of the processing box 1 for collection for reuse. When the processing of the cam is completed, cut off the power of the isolation electromagnet 10, and the cam tumbling basket 5 will open. Send the variable-speed cam to the surface of the cam baffle 11, and then the variable-speed cam will slide to the outside of the discharge port 13 of the processing box 1 to complete the processing of the variable-speed cam.

[0034] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
