Description

Technical Field

[0001] This utility model relates to the field of camshaft processing technology, and in particular to a camshaft deburring device. Background Technology

[0002] The camshaft is a key component in an internal combustion engine, used to control the opening and closing of valves, ensuring fuel-air mixing and exhaust gas expulsion. It precisely controls the timing and stroke of valve movement through the shape and position of the cams, directly affecting engine performance, efficiency, and emissions. Camshafts are typically made of high-strength alloy steel, precision-machined and heat-treated to ensure durability and precision. Therefore, the camshaft blanks need to be deburred and polished; otherwise, burrs will form irregular protrusions on the camshaft surface, affecting its precision.

[0003] A Chinese patent discloses a grinding head device for deburring camshafts [Application No.: CN202420207377.3, Publication No.: CN221936245U]. It includes a first connecting rod and a second connecting rod that can move in opposite directions, as well as a rotatable brush. Both the first and second connecting rods are equipped with a fixing mechanism for securing the camshaft. A first motor is fixedly connected to one side of the first connecting rod, and the output shaft of the first motor passes through the first connecting rod and connects to the fixing mechanism. The fixing mechanism includes a mounting block and a threaded sleeve. The mounting block has threads and is screwed into the threaded sleeve. A funnel-shaped cylinder is fixedly connected to one side of the threaded sleeve, and multiple elastic locking rods that cooperate with the funnel-shaped cylinder are fixedly connected to one side of the mounting block. Although this patent's technical solution can effectively remove burrs from the camshaft surface, it still requires manual loading and unloading. Since a single camshaft is often quite heavy, this results in high workload for workers and a labor-intensive processing process. Utility Model Content

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A camshaft deburring device includes: a clamping device 1, a feeding device 2, a grinding device 3, and a photoelectric switch 4.

[0020] The clamping device 1 can adopt an existing chuck-like structure for clamping or releasing the camshaft. The clamping devices 1 are respectively arranged on both sides of the feeding device 2. The bottom of the clamping device 1 is provided with a sliding rail, so that the two clamping devices 1 can move closer or further apart.

[0021] The grinding device 3 is located on one side of the feeding device 2. The grinding brush of the grinding device 3 corresponds to the clamping area of ​​the clamping device 1. The grinding device 3 can adopt an existing grinding structure, which has a brush for grinding burrs and a power structure for driving the brush to rotate continuously.

[0022] The feeding device 2 includes a conveyor chain 21, a support plate 22, and an actuating cylinder 23. The support plate 22 is used to support the camshaft to be processed. The support plate 22 is connected to the conveyor chain 21. The actuating cylinders 23 are respectively arranged on both sides of the conveyor chain 21. The extension direction of the actuating cylinders 23 is towards the clamping area of ​​the clamping device 1.

[0023] Specifically, the support plate 22 has forklift holes 222 that penetrate through it. The support plate 22 also has support grooves 221. These grooves 221 are symmetrically arranged on the upper and lower sides of the support plate 22. The grooves 221 are semi-circular in shape. The diameter of the grooves 221 corresponds to the diameter of the camshaft. Furthermore, there are multiple support grooves 221, evenly distributed from one end of the support plate 22 to the other. On the other hand, the width of the support plate 22 is less than the length of the camshaft, so that the camshaft protrudes beyond the support plate 22.

[0024] The conveyor chain 21 is in a closed loop. A power motor is connected to the conveyor chain 21. Driven by the power motor, the conveyor chain 21 can rotate cyclically. Furthermore, the conveyor chain 21 is equipped with multiple clamping structures 211. These clamping structures 211 are evenly distributed from one end of the support plate 22 to the other. Each clamping structure 211 includes a positioning block 2111, a clamping plate 2112, a connecting rod 2113, and pins 2114. The positioning block 2111 is located at both ends of the connecting rod 2113. The shape of the positioning block 2111 corresponds to the support groove 221. When the support plate 22 is placed on the conveyor chain 21, the support plate 22 can engage with the positioning block 2111 through the support groove 221. The positioning block 2111 has a groove corresponding to the conveyor chain 21. The positioning block 2111 is connected to the clamping plate 2112. The clamping plate 2112 fits against the side wall of the support plate 22 to clamp the support plate 22. The pin 2114 passes through the positioning block 2111 and the link of the conveyor chain 21.

[0025] The actuating cylinder 23 is arranged vertically. A pusher plate 231 is fixedly provided at the extended end of the actuating cylinder 23. The pusher plate 231 is arc-shaped.

[0026] It also includes a photoelectric switch 4. The sensing direction of the photoelectric switch 4 is towards the carrier plate 22. The photoelectric switch 4 is connected to the clamping device 1. The photoelectric switch 4 is electrically connected to the feeding device 2. Specifically, the photoelectric switch 4 includes a light output end and a light receiving end, which are arranged opposite each other and respectively installed on the two clamping devices 1. The optical fiber output from the light output end corresponds to the center of the carrier groove 221. Because the carrier groove 221 is semi-circular, the carrier groove 221 itself will not block the light. When a camshaft is placed in the carrier groove 221, the camshaft will block the light, thereby triggering the photoelectric switch 4.

[0027] In practical applications, the camshaft is pre-placed into the bearing groove 221 in conjunction with the production of camshaft blanks. At this time, the end of the camshaft protrudes beyond the bearing plate 22. Thus, the bearing plate 22 can simultaneously support several camshafts to be processed. Workers use a forklift to place the bearing plate 22 onto the conveyor chain 21 through the forklift holes 222 on the bearing plate 22, causing the bearing groove 221 on the lower side of the bearing plate 22 to engage with the positioning block 2111. At this time, the clamping plate 2112 is in contact with the side of the bearing plate 22. Thus, the clamping structure 211 clamps the bearing plate 22, ensuring a stable connection between the bearing plate 22 and the conveyor chain 21.

[0028] Once the support plate 22 is placed stably, the power motor connected to the conveyor chain 21 is started. Driven by the power motor, the conveyor chain 21 gradually transports the support plate 22 to the actuating cylinder 23. As the support plate 22 gradually approaches the actuating cylinder 23, the first camshaft on the support plate 22 eventually blocks the photoelectric switch 4, thereby triggering the actuating cylinder 23. At the same time, the power motor stops. At this time, the extended end of the actuating cylinder 23 extends, causing the pusher plate 231 to push the camshaft towards the clamping area of ​​the clamping device 1. The pusher plate 231 is arc-shaped, which can correct the position of the camshaft to a certain extent when pushing it, thus facilitating subsequent clamping. After the camshaft enters the clamping area, the clamping device 1 is controlled to operate. The two clamping devices 1 move closer to each other, thereby clamping the camshaft. After the clamping device 1 stably clamps the camshaft, the actuating cylinder 23 retracts, and the grinding device 3 is activated to grind the camshaft. Preferably, a delay time can be preset so that after the photoelectric switch 4 is triggered, the power motor can still run for a period of time, allowing the conveyor chain 21 to advance a certain distance, so that the light emitted by the photoelectric switch 4 coincides with the axis of the camshaft, thereby ensuring that the stopping point of the camshaft is fully matched with the clamping device 1, facilitating subsequent clamping.

[0029] During the camshaft grinding process, the support groove 221 for supporting the camshaft is empty. At this time, the light emitted by the photoelectric switch 4 is not blocked. After the camshaft is processed, the control cylinder 23 is activated, causing the pusher plate 231 to extend into the clamping area of ​​the clamping device 1. Subsequently, the control clamping device 1 releases the ground camshaft, allowing it to fall onto the pusher plate 231. The control cylinder 23 is activated again, thus placing the ground camshaft back into the corresponding support groove 221. At this time, the photoelectric switch 4 is blocked again by the camshaft, triggering the conveyor chain 21 to transport it. When the area between two support grooves 221 moves to the photoelectric switch 4, the light is not blocked. When the next support groove 221 moves to the photoelectric switch 4, the light is blocked again. Based on the aforementioned changes, the aforementioned process is triggered again, thereby processing the next camshaft. Thus, by repeating the aforementioned process, the camshafts can be processed one by one.

[0030] Once all camshafts have been machined, workers can use a forklift to remove the support plate 22 from the conveyor chain 21 and send it to the storage area. Then, the next support plate 22 is placed on the conveyor chain 21.

[0031] In summary, this invention can assist in the loading and unloading process of camshafts, thereby effectively reducing the workload of workers and thus reducing manpower consumption.

[0032] It is worth noting that because the area of ​​the actuating cylinder 23 is easily obstructed by other structures, photoelectric switch 4 is used for auxiliary control. The control of other devices can be performed manually by operators or by an automatic control system based on the aforementioned actuation process. The control system is existing technology, and the specific control method will not be described in detail here.
