Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cam inner hole processing, and specifically relates to a cam inner hole automatic processing equipment. BACKGROUND

[0002] The cam inner hole automatic processing equipment plays a very key role in modern industrial production, and the cam inner hole polishing equipment, as an important branch of the cam inner hole automatic processing equipment, is dedicated to fine polishing treatment of the cam inner hole.

[0003] At present, the traditional cam inner hole polishing equipment is to place the cam at the top end of the worktable. Then, the polishing assembly starts to work to grind the cam inner hole.

[0004] However, in the actual use process, when the polishing assembly completes the grinding of one cam inner hole, the operator needs to manually take down the polished cam from the worktable. After taking down the polished cam, the operator needs to place the unpolished cam on the worktable and readjust the position of the cam to ensure that the polishing assembly can accurately align the inner hole for processing. This series of feeding, discharging and adjusting operations not only increases the labor cost, but also makes the equipment frequently stop during the polishing process, which cannot realize continuous production, thereby leading to low overall polishing efficiency.

[0015] Preferably, the limiting assembly comprises an insert piece arranged on the surface of the mounting roller, one side of the insert piece is provided with a magnet, and a fixing groove is formed in the bottom end of the insert piece.

[0016] A conveying mechanism is arranged at the top end of the mounting shell, which can push the cam body and the insert piece to move on the surface of the mounting roller.

[0018] Preferably, the conveying mechanism comprises a sliding rail fixedly connected to the top end of the mounting shell, a push plate is slidably connected to the surface of the sliding rail, a motor is fixedly arranged at the top end of the mounting shell, a lead screw located in the inside of the push plate is fixedly arranged on the output end of the motor, and the lead screw is threadedly connected with the push plate.

[0019] Preferably, it further comprises:

[0020] A positioning assembly is arranged on one side of the workbench, which comprises a square rod fixedly connected to one side of the workbench, and a plurality of rolling balls are rollingly connected to one side of the square rod close to the insert piece.

[0021] Preferably, the top end of the stop block is of an arc design, one side of the stop block is of an inclined surface design, and the inclined surface of the stop block is of a smooth design.

[0022] Preferably, the fixing assembly comprises a bidirectional hydraulic cylinder fixedly connected to the inside of the workbench, and a limiting plate is fixedly arranged on the output shaft of the bidirectional hydraulic cylinder.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] This invention drives a grinding mechanism to push out the insert through a push rod, thus removing the limit on the cam body. A pneumatic cylinder then uses its output shaft to push the fixed housing and the stop block to move. The stop block guides the cam body into the worktable, and the cam body moves between two limit plates. A bidirectional hydraulic cylinder can then be driven to move the limit plates, thereby limiting the cam body. Finally, by removing the fixation of the cam body, the pneumatic cylinder drives the stop block to push the cam body into the worktable, thus achieving continuous feeding. This greatly reduces waiting time and manual intervention during processing, significantly improving processing efficiency.

[0027] This invention uses a driving moving component to move the grinding component away from the surface of the worktable, while the sealing rod slides inside the air intake pipe, compressing the air inside the air intake pipe and the sealing cylinder. The compressed air pushes the push rod to lift the insert, moving it away from the surface of the cam body. The insert falls onto the top of the base along the inclined surface on one side of the mounting shell. Then, the pneumatic cylinder drives the stop block to send the cam body into the worktable, thereby grinding multiple cam bodies. Finally, the grinding mechanism, in conjunction with the sealing rod, pushes the push rod away from the surface of the cam body, facilitating the pneumatic cylinder to push the cam body into the worktable. This avoids pauses and adjustments caused by limiting the cam body, making the entire production process more compact and continuous. Attached Figure Description

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0040] As Figures 1 to 10 shown, the present application provides a cam inner hole automatic machining equipment, comprising a base 1, further comprising:

[0041] A polishing mechanism 2 is arranged at the top end of the base 1;

[0042] A pushing mechanism 3 is arranged at the top end of the base 1;

[0043] The pushing mechanism 3 comprises a mounting shell 301 fixedly connected to the top end of the base 1, the top end of the mounting shell 301 is provided with a mounting roller 302, the mounting roller 302 is fixedly installed with a workbench 307 close to one end of the polishing mechanism 2, the pneumatic cylinder 303 is fixedly installed inside the mounting roller 302 close to one end of the workbench 307, the output shaft of the pneumatic cylinder 303 is fixedly installed with a fixed shell 304, the fixed shell 304 is slidingly connected with a stop block 306 inside, and the stop block 306 is elastically connected with the fixed shell 304 through an elastic piece one 305;

[0044] A cam body 9 is arranged on the surface of the mounting roller 302, and the number of the cam body 9 is multiple;

[0045] A limiting assembly 5 is arranged on the surface of the mounting roller 302;

[0046] The trigger mechanism 4 is arranged in the interior of the mounting shell 301 and can push the limiting assembly 5 to move;

[0047] The fixing assembly 7 is arranged in the interior of the workbench 307, and the fixing assembly 7 is a mirror image design and can fix the cam body 9 entering the interior of the workbench 307.

[0048] With the above scheme: the operator can put multiple cam bodies 9 on the surface of the mounting roller 302, insert the limiting assembly 5 between the multiple cam bodies 9, and the bottom end of the limiting assembly 5 is in contact with the surface of the mounting roller 302, then the mounting roller 302 with the cam bodies 9 can be fixed on the top end of the mounting shell 301 through bolts, then the polishing mechanism 2 can be driven to move, the polishing mechanism 2 drives the trigger mechanism 4 to push the limiting assembly 5 away from the surface of the cam body 9, thereby canceling the fixation of the cam body 9, while the limiting assembly 5 is away from the surface of the cam body 9, the compressed elastic member one 305 pushes the stop block 306 to move upwards, then the pneumatic cylinder 303 is driven to move the output end to push the fixing shell 304, the elastic member one 305 and the stop block 306 to move, and the stop block 306 pushes the cam body 9 into the interior of the workbench 307, and since the inner wall of the workbench 307 is in contact with the surface of the cam body 9, the cam body 9 can be supported, and then the workbench 307 moves between the two fixing assemblies 7, and the fixing assembly 7 can limit the cam body 9, then the polishing mechanism 2 can be driven to enter the inner hole of the cam body 9 to polish the inner hole thereof;

[0049] After polishing, the polishing mechanism 2 is driven to move away from the inner hole of the cam body 9, at the same time, the fixing assembly 7 is driven to cancel the limitation of the cam body 9, then the moving polishing mechanism 2 drives the trigger mechanism 4 to move the limiting assembly 5 away from the surface of the cam body 9, then the pneumatic cylinder 303 is driven to push the stop block 306 to push the cam body 9 which has not been polished into the interior of the workbench 307, thereby completing the continuous processing of multiple cam bodies 9, then the cam body 9 pushes the polished cam body 9 away from the interior of the workbench 307, and the polished cam body 9 falls into the collecting groove at the bottom end of the workbench 307, finally, by canceling the fixation of the cam body 9, the pneumatic cylinder 303 drives the stop block 306 to push the cam body 9 into the interior of the workbench 307, thereby realizing continuous feeding, greatly reducing the waiting time and human intervention in the processing process, and significantly improving the processing efficiency.

[0050] As shown in Figure 2 and Figure 6 , the polishing mechanism 2 comprises a moving assembly 201 fixedly connected to the top end of the base 1, and the surface of the moving assembly 201 is provided with a polishing assembly 202.

[0051] Adopting the above scheme: through the design of the polishing mechanism 2, the moving assembly 201 can be driven to drive the polishing assembly 202 to enter or move away from the inner hole of the cam body 9, and after the polishing assembly 202 enters the inner hole of the cam body 9, the polishing assembly 202 can be driven to polish the inner hole of the cam body 9.

[0052] As shown in Figure 3 and Figure 6 The limiting assembly 5 includes an insert piece 501 arranged on the surface of the mounting roller 302, one side of the inside of the insert piece 501 is provided with a magnet 502, and the bottom end of the insert piece 501 is provided with a fixing groove 503.

[0053] The conveying mechanism 6 is arranged at the top end of the mounting shell 301, which can push the cam body 9 and the insert piece 501 to move on the surface of the mounting roller 302.

[0054] Adopting the above scheme: through the design of the limiting assembly 5, when the cam body 9 is inserted into the surface of the mounting roller 302, the insert piece 501 can be inserted between each cam body 9, and the insert piece 501 will be sleeved on the surface of the cam body 9, and the magnet 502 will be in contact with the cam body 9, thereby being adsorbed on the surface of the cam body 9, then after one of the insert pieces 501 is ejected by the triggering mechanism 4, the conveying mechanism 6 can be driven to push the cam body 9 and the insert piece 501 to move, thereby ensuring the continuity of feeding.

[0055] As shown in Figure 6 and Figure 7 The triggering mechanism 4 includes a sealing cylinder 401 fixedly connected to the inside of the mounting shell 301, a push rod 402 located at the bottom end of the insert piece 501 is slidably connected to the inside of the sealing cylinder 401, an air inlet pipe 403 is fixedly installed on the outer surface of the sealing cylinder 401, a sealing rod 404 is slidably connected to the inside of the air inlet pipe 403, a connecting rod 405 is fixedly installed on one end of the sealing rod 404, and one end of the connecting rod 405 is fixedly connected to the surface of the moving assembly 201.

[0056] Adopting the above scheme: through the design of the trigger mechanism 4, when the polishing mechanism 2 moves away from the inner wall of the cam body 9, the connecting rod 405 and the sealing rod 404 will move, and the sealing rod 404 will move inside the air inlet pipe 403. Because the surface of the sealing rod 404 is in close contact with the inner wall of the air inlet pipe 403, the moving sealing rod 404 will extrude the air inside the air inlet pipe 403 and the sealing cylinder 401. As the air inside the sealing cylinder 401 is compressed, the compressed air will push the push rod 402 upwards, and the push rod 402 will enter the fixed groove 503 and push the insert piece 501 upwards. Because one end of the insert piece 501 is heavy, and as the insert piece 501 moves away from the surface of the cam body 9, it will tilt towards the heavy end, thereby falling to the top end of the base 1. Then the air cylinder 303 can be driven to make the stop block 306 send the cam body 9 into the workbench 307, and then the moving assembly 201 is driven to make the polishing assembly 202 continuously polish the cam body 9. Finally, the push rod 402 is pushed by the sealing rod 404 of the polishing mechanism 2 to move away from the surface of the cam body 9, thereby facilitating the air cylinder 303 to push the cam body 9 into the workbench 307, avoiding the stop and adjustment caused by limiting the cam body 9, and making the entire production process more compact and coherent.

[0057] As shown in Figure 2 and Figure 5 , the conveying mechanism 6 comprises a sliding rail 601 fixedly connected to the top end of the mounting shell 301, the surface of the sliding rail 601 is slidingly connected with a push plate 602, and the top end of the mounting shell 301 is fixedly installed with a motor 603. The output end of the motor 603 is fixedly installed with a lead screw 604 located inside the push plate 602, and the lead screw 604 is in threaded connection with the push plate 602.

[0058] Adopting the above scheme: through the design of the conveying mechanism 6, after one of the cam bodies 9 is sent into the workbench 307 and the push rod 402 is retracted into the sealing cylinder 401, the motor 603 can be driven to rotate the lead screw 604, and the push plate 602 will move on the surface of the lead screw 604. Then the push plate 602 will push the cam body 9 and the insert piece 501 to move, and one of the cam bodies 9 and the insert piece 501 will move to the feeding station, waiting for the next feeding.

[0059] As shown in Figure 8 and Figure 9 , it further comprises:

[0060] The positioning assembly 8 is arranged on one side of the workbench 307, and the positioning assembly 8 comprises a square rod 801 fixedly connected to one side of the workbench 307. A ball 802 is rollingly connected to one side of the square rod 801 close to the insert piece 501.

[0061] Adopting the above scheme: through the design of the positioning assembly 8, when the push plate 602 pushes the insert sheet 501 and the cam body 9 moves, the surface of the insert sheet 501 will be in contact with the surface of the ball 802, thereby being able to position it, and when the push rod 402 pushes the insert sheet 501 to move, the ball 802 will roll, thereby ensuring the smoothness of the movement of the insert sheet 501.

[0062] As shown in Figure 4 and Figure 6 , the top end of the stop block 306 is arc-shaped, one side of the stop block 306 is beveled, and the bevel of the stop block 306 is smooth.

[0063] Adopting the above scheme: through the design of the stop block 306, since one side of the stop block 306 is beveled, when the cam body 9 and the insert sheet 501 move and contact the bevel, the stop block 306 is squeezed into the fixed shell 304, and the elastic piece 305 is compressed, then the bottom end of the insert sheet 501 stays on the surface of the stop block 306, and when the insert sheet 501 moves away from the surface of the cam body 9, the stop block 306 moves out, thereby facilitating the pushing of the cam body 9 into the workbench 307, and the top end of the stop block 306 is arc-shaped, which is in the same horizontal line as the surface of the mounting roller 302 during the contraction process.

[0064] As shown in Figure 8 and Figure 10 , the fixed assembly 7 comprises a double-acting hydraulic cylinder 701 fixedly connected inside the workbench 307, and the output shaft of the double-acting hydraulic cylinder 701 is fixedly installed with a limiting plate 702.

[0065] Adopting the above scheme: through the design of the fixed assembly 7, when the cam body 9 moves between the two limiting plates 702, the double-acting hydraulic cylinder 701 can be driven to move the limiting plate 702 towards the surface of the cam body 9, and through the cooperation of the two limiting plates 702, the cam body 9 can be limited, ensuring the stability of the polishing of the inner hole of the cam body 9.

[0066] As shown in Figure 1 and Figure 6 , the surface of the push rod 402 is in contact with the inner wall of the sealing cylinder 401, the top end of the push rod 402 is round, the push rod 402 is mirror image, one side of the mounting shell 301 is beveled, and the insert sheet 501 is located at the top end of the bevel.

[0067] Adopt the above scheme: through the design of push rod 402, because the surface of push rod 402 and the inner wall of sealing cylinder 401 fit, thereby ensuring that the air inside sealing cylinder 401 pushes push rod 402 to move, and the top end of push rod 402 is designed as a round corner, when the insert piece 501 is separated from the surface of cam body 9, it is ensured that push rod 402 can slide inside fixed groove 503, through the design of mounting shell 301, because one side of mounting shell 301 is designed as an inclined surface, when the insert piece 501 is separated from the surface of cam body 9, it will fall on the inclined surface, and mounting shell 301 will guide insert piece 501 to the top end of base 1.

[0068] The working principle and use process of the application are as follows:

[0069] First, the operator needs to insert multiple cam bodies 9 into the surface of mounting roller 302, and insert insert piece 501 between multiple cam bodies 9, so that it is sleeved on the surface of cam body 9, ensuring that each cam body 9 moves the same distance, then magnet 502 will be attracted to the surface of cam body 9, then mounting roller 302 can be installed at the top end of mounting shell 301, because drive moving assembly 201 makes polishing assembly 202 move away from the surface of workbench 307, sealing rod 404 will slide inside air inlet pipe 403, extruding the air inside air inlet pipe 403 and sealing cylinder 401, the extruded air will push push rod 402 to lift insert piece 501, so that it moves away from the surface of cam body 9, insert piece 501 will fall on the top end of base 1 along the inclined surface on one side of mounting shell 301;

[0070] At this time, compressed elastic member one 305 will push stop block 306 to move, then drive air cylinder 303 makes its output shaft push fixed shell 304 and stop block 306 to move, and stop block 306 will guide cam body 9 into workbench 307, and cam body 9 will move between two limiting plates 702, then drive bidirectional hydraulic cylinder 701 to move limiting plate 702, thereby limiting cam body 9,

[0071] Then drive moving assembly 201 to make polishing assembly 202 enter the inner hole of cam body 9, so as to polish its inner hole, while polishing assembly 202 enters the inner hole of cam body 9, sealing rod 404 will reset, and push rod 402 will retract into sealing cylinder 401, at this time, drive motor 603 to make screw rod 604 rotate, push plate 602 will slide on the surface of screw rod 604, push plate 602 will push the unpolished cam body 9 to move, then insert piece 501 will contact with ball 802, so as to position it, and after the polishing of the inner hole of cam body 9 is completed, the above operation can be repeated, so as to continuously guide cam body 9 into workbench 307, improving the polishing efficiency.
