However, during the actual chamfering process of the rivet, during the processing of the rivet, the detection mechanism is prone to failure after long-term use, which increases the subsequent maintenance cost and reduces the chamfering efficiency of the rivet. Therefore, an automatic rivet chamfering equipment with a better chamfering device is designed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic rivet chamfering equipment and a rivet chamfering method, which solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: An automatic rivet chamfering device includes a working frame and a feeding mechanism. A lifting plate is slidably mounted on the surface of the working frame. An electric push rod is fixedly mounted below the top of the working frame.

It further includes: a chamfering device, which includes a support plate, a rotating column, a rotating feeding plate, a limiting plate, a clamping block, a connecting plate, a pressing plate, a receiving rod, a connecting rod, a sliding plate, a sliding rod and a ratchet. When the lifting plate moves downward, it drives one end of the connecting rod to move downward. The downward movement of one end of the connecting rod drives the sliding plate to move towards the rotating column. The movement of the sliding plate drives the sliding rod to move. The support plate is fixedly mounted on the surface of the working frame. The rotating column rotatably penetrates the upper and lower walls of the support plate. The rotating feeding plate is fixedly mounted on the circumferential surface of the rotating column. The limiting plate is fixedly mounted on the surface of the working frame.

The pressing plate is fixedly mounted below the lifting plate. The receiving rod is fixedly mounted below the pressing plate. The connecting rod is rotatably mounted below the lifting plate. The sliding plate is rotatably mounted at one end of the connecting rod away from the lifting plate. A moving groove is formed on the surface of the sliding plate. The sliding rod is slidably mounted on the inner wall of the moving groove. The ratchet is mounted on the circumferential surface of the rotating column. The sliding plate is slidably connected to the support plate. The movement of the connecting plate drives the clamping block to move. The clamping block moves to contact and clamp the rivet. The movement of the sliding plate drives the sliding rod to move. When the sliding rod moves, it drives the ratchet to rotate under the limited state.

[0007] According to the above technical solution, a chute is formed on the surface of the working frame. The pressing plate is slidably connected to the inner wall of the chute. The receiving rod is slidably connected to the inner wall of the chute. A guiding groove is formed on the surface of the connecting plate. One end of the receiving rod away from the pressing plate contacts the inner wall of the guiding groove. One end of the clamping block away from the connecting plate is set as an arc surface. The downward movement of the receiving rod drives the connecting plate to move towards the rotating feeding plate through the guiding groove. The movement of the connecting plate drives the clamping block to move. The clamping block moves to contact and clamp the rivet.

[0008] According to the above technical solution, a feeding groove is formed on the surface of the rotating feeding plate. The number of the feeding grooves is the same as that of the tooth blocks on the surface of the ratchet. The rotation of the ratchet drives the rotation of the rotating column. The rotation of the rotating column drives the rotation of the rotating feeding plate. The rotation of the rotating feeding plate transports the rivets on the surface of the feeding mechanism to the position to be processed and moves the rivets with chamfering completed out of the position to be processed. A spring is arranged between the inner wall of the sliding rod and the moving groove. The sliding rod moves to compress the spring and reset under its action. After the sliding rod moves and resets, it engages with the ratchet.

[0009] According to the above technical solution, a lubricating device for assisting chamfering is provided on the surface of the working frame. The lubricating device includes an oil storage tank and a filter plate. The oil storage tank is fixedly installed above the working frame, and the filter plate is fixedly installed on the inner wall of the oil storage tank. The lubricating device further includes a metering frame, a pressing frame, a pressing rod, a fixing plate, and a guide oil pipe.

The metering frame is fixedly installed above the working frame. The pressing frame is slidably installed on the inner wall of the metering frame. The pressing rod is fixedly installed above the pressing frame. The fixing plate is fixedly installed above the limiting plate. The guide oil pipe fixedly penetrates the left and right walls of the fixing plate. The pressing frame continues to move downward to pump the cutting oil inside the metering frame into the inside of the guide oil pipe and spray it on the rivets at the position to be processed.

[0010] According to the above technical solution, the guide oil pipe is elastic. An oil outlet hole is provided on the surface of the oil storage tank, and an oil inlet hole is provided on the surface of the metering frame. The oil storage tank and the metering frame are communicated through the oil outlet hole and the oil inlet hole. The downward movement of the pressing frame closes the oil inlet hole to prevent the cutting oil inside the oil storage tank from continuing to enter the inside of the metering frame.

[0011] According to the above technical solution, one end of the guide oil pipe away from the fixing plate fixedly penetrates the upper and lower walls of the pressing frame. One end of the pressing rod away from the pressing frame is fixedly connected to the connecting plate. The cutting oil can wash the debris generated during the chamfering process into the inside of the oil storage tank, and filter out the debris under the action of the filter plate.

[0012] According to the above technical solution, a discharging device is further included. The discharging device includes a material guiding rod, a drainage rod, an L-shaped rod, a convex block, and a receiving block. When the pressing frame moves downward, it contacts and squeezes the L-shaped rod to move away from the metering frame. The movement of the L-shaped rod drives the receiving block to move. The material guiding rod is fixedly installed on the inner wall of the oil storage tank. The drainage rod is fixedly installed on the circumferential surface of the material guiding rod. The L-shaped rod is slidably installed on the inner wall of the oil outlet hole. The convex block is fixedly installed below the filter plate. A lifting groove is provided on the surface of the L-shaped rod. The receiving block is slidably installed on the inner wall of the lifting groove. The cutting oil on the surface of the material guiding rod will be drained into the inside of the oil storage tank under the action of the drainage rod.

The lower part of the convex block is provided with a first arc surface, and the upper part of the receiving block is provided with a second arc surface. A first telescopic elastic rod is provided between the L-shaped rod and the inner wall of the oil storage tank, and a second telescopic elastic rod is provided between the receiving block and the inner wall of the lifting groove. After the second telescopic elastic rod contracts and resets, the receiving block repeatedly contacts the convex block and generates vibration.

[0014] A usage method of a rivet automatic chamfering device, using the above-mentioned rivet automatic chamfering device, includes the following steps:

[0015] Step 1: The rivets are transported to the surface of the rotating feeding tray through the feeding mechanism. Subsequently, the electric push rod and the servo motor are started, and the output end of the electric push rod moves downward to drive the lifting plate to move downward.

[0016] Step 2: The downward movement of the lifting plate drives the pressing plate and the receiving rod to move downward. The downward movement of the receiving rod drives the connecting plate to move towards the rotating feeding tray through the guiding groove. The movement of the connecting plate drives the clamping block to move and clamp and fix the rivets.

[0017] Step 3: While the lifting plate moves downward, it drives the sliding plate to move towards the rotating column through the connecting rod. The movement of the sliding plate drives the sliding rod to move and engage with the ratchet under the action of the spring.

[0018] Step 4: The downward movement of the lifting plate drives the servo motor to move downward. The downward movement of the servo motor drives the chamfering tool to move downward to contact the rivets, and rotates under the action of the servo motor to chamfer the rivets.

[0019] Step 5: After chamfering, the electric push rod drives the lifting plate to move upward, and under the action of the connecting rod and the sliding plate, drives the sliding rod to move away from the ratchet. When the sliding rod moves, it drives the ratchet to rotate under the limited state to transport the rivets on the surface of the feeding mechanism to the position to be processed, and removes the rivets that have been chamfered from the position to be processed.

[0020] The present invention provides an automatic rivet chamfering device. It has the following beneficial effects:

[0021] (1) In this automatic rivet chamfering device, through the coordinated operation among the lifting plate, electric push rod, servo motor, chamfering tool, support plate, rotating column, rotating feeding tray, limiting plate, clamping block, connecting plate, pressing plate, receiving rod, connecting rod, sliding plate, sliding rod and ratchet, the clamping block moves to contact and clamp and fix the rivets. At the same time, the automatic loading and unloading of the rivets is realized through the sliding rod and the ratchet, and the full-automatic chamfering work of the rivets is achieved, effectively reducing the failure rate of the equipment. There is no need for staff to place the rivets, and it can adapt to rivets of different lengths, improving the applicability and processing efficiency of the equipment.

[0022] (2) The automatic rivet chamfering equipment, through the coordinated operation among the oil storage tank, filter plate, quantitative frame, pressing frame, pressing rod, fixed plate and oil guide pipe, pumps the cutting oil inside the quantitative frame into the oil guide pipe and sprays it on the rivets at the position to be processed, realizing the quantitative spraying at the chamfering part, which can effectively reduce the friction between the chamfering tool and the rivets, reduce the temperature in the cutting area, thereby preventing the deformation of the rivets caused by overheating or the wear of the tools. At the same time, the cutting oil filtered with debris is communicated with the quantitative frame under the action of the oil outlet hole, thus realizing the recycling of the cutting oil, improving the utilization rate of the cutting oil, reducing the subsequent maintenance cost and improving the chamfering efficiency of the rivets.

[0023] (3) The automatic rivet chamfering equipment, through the coordinated operation among the material guiding rod, drainage rod, L-shaped rod, convex block, receiving block, first telescopic spring rod and second telescopic spring rod, makes the receiving block repeatedly contact with the convex block and generate vibration. The vibration can effectively improve the filtering effect of the filter plate on the debris, avoid excessive accumulation of debris causing blockage, and thus affect the recycling of the cutting oil. At the same time, the cutting oil on the surface of the material guiding rod will be drained into the oil storage tank under the action of the drainage rod, further realizing the utilization and recycling effect of the cutting oil and improving the processing efficiency of the rivets.

When the sliding rod 17 moves, it drives the ratchet wheel 18 to rotate under the limited state to transport the rivets on the surface of the feeding mechanism 2 to the position to be processed and remove the rivets with chamfers completed from the position to be processed.

[0042] During the operation of this embodiment: The rivets are transported to the surface of the rotating feeding tray 9 through the feeding mechanism 2. Subsequently, the electric push rod 4 and the servo motor 5 are started. The output end of the electric push rod 4 moves downward to drive the lifting plate 3 to move downward.

At the same time that the lifting plate 3 moves downward, it drives one end of the connecting rod 15 to move downward. The downward movement of one end of the connecting rod 15 drives the sliding plate 16 to move toward the rotating column 8. The movement of the sliding plate 16 drives the sliding rod 17 to move.

[0043] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, a lubricating device for assisting chamfering is provided on the surface of the working frame 1. The lubricating device includes an oil storage tank 201 and a filter plate 202. The oil storage tank 201 is fixedly installed above the working frame 1, and the filter plate 202 is fixedly installed on the inner wall of the oil storage tank 201. The lubricating device further includes a metering frame 203, a pressing frame 204, a pressing rod 205, a fixing plate 206, and a guide oil pipe 207. While the connecting plate 12 moves downward, it drives the pressing rod 205 to move downward. The downward movement of the pressing rod 205 drives the pressing frame 204 to move downward. The metering frame 203 is fixedly installed above the working frame 1, and the pressing frame 204 is slidably installed on the inner wall of the metering frame 203. The pressing rod 205 is fixedly installed above the pressing frame 204. The fixing plate 206 is fixedly installed above the limiting plate 10. The guide oil pipe 207 fixedly penetrates the left and right walls of the fixing plate 206. The pressing frame 204 continues to move downward to pump the cutting oil inside the metering frame 203 into the inside of the guide oil pipe 207 and spray it on the rivets at the position to be processed, realizing the quantitative spraying of the chamfering part, which can effectively reduce the friction between the chamfering tool 6 and the rivets and reduce the temperature in the cutting area.

[0044] The guide oil pipe 207 is elastic. An oil outlet hole is provided on the surface of the oil storage tank 201, and an oil inlet hole is provided on the surface of the metering frame 203. The oil storage tank 201 and the metering frame 203 are communicated through the oil outlet hole and the oil inlet hole. The downward movement of the pressing frame 204 closes the oil inlet hole to prevent the cutting oil inside the oil storage tank 201 from continuing to enter the inside of the metering frame 203.

[0045] One end of the guide oil pipe 207 away from the fixing plate 206 fixedly penetrates the upper and lower walls of the pressing frame 204. One end of the pressing rod 205 away from the pressing frame 204 is fixedly connected to the connecting plate 12. The cutting oil can wash the debris generated during the chamfering process into the inside of the oil storage tank 201, and filter out the debris under the action of the filter plate 202. The cutting oil filtered out of the debris is communicated with the metering frame 203 under the action of the oil outlet hole, thereby realizing the recycling of the cutting oil.

[0046] It further includes a discharging device. The discharging device includes a guiding rod 211, a guiding rod 212, an L-shaped rod 213, a convex block 214, and a receiving block 215. When the pressing frame 204 moves downward, it contacts and squeezes the L-shaped rod 213 to move away from the metering frame 203. The movement of the L-shaped rod 213 drives the receiving block 215 to move. The guiding rod 211 is fixedly installed on the inner wall of the oil storage tank 201, the guiding rod 212 is fixedly installed on the circumferential surface of the guiding rod 211. The L-shaped rod 213 is slidably installed on the inner wall of the oil outlet hole. The convex block 214 is fixedly installed below the filter plate 202. A lifting groove is provided on the surface of the L-shaped rod 213, and the receiving block 215 is slidably installed on the inner wall of the lifting groove. The cutting oil on the surface of the guiding rod 211 will be guided into the inside of the oil storage tank 201 under the action of the guiding rod 212, further realizing the utilization and recycling effect of the cutting oil and improving the processing efficiency of the rivets.

[0047] The material guiding rod 211 is inclined, one end of the L-shaped rod 213 close to the quantitative box 203 is set as an inclined plane, the lower part of the convex block 214 is set as a first arc surface, the upper part of the receiving block 215 is set as a second arc surface, a telescopic spring rod one 216 is arranged between the L-shaped rod 213 and the inner wall of the oil storage tank 201, a telescopic spring rod two 217 is arranged between the receiving block 215 and the inner wall of the lifting groove, and after the telescopic spring rod two 217 contracts and then resets, the receiving block 215 contacts the convex block 214 repeatedly and generates vibration. The vibration can effectively improve the filtering effect of the filter plate 202 on the debris, avoid excessive accumulation of debris causing blockage, thereby affecting the recycling of the cutting oil, and reducing the subsequent maintenance cost.

[0048] When this embodiment works: while the connecting plate 12 moves downward, it drives the pressure rod 205 to move downward. The downward movement of the pressure rod 205 drives the pressure frame 204 to move downward. The downward movement of the pressure frame 204 closes the oil inlet hole, preventing the cutting oil inside the oil storage tank 201 from continuing to enter the inside of the quantitative box 203. Subsequently, the pressure frame 204 continues to move downward to pump the cutting oil inside the quantitative box 203 into the inside of the guide oil pipe 207 and spray it on the rivets at the position to be processed, realizing the quantitative spraying of the chamfering part, which can effectively reduce the friction between the chamfering tool 6 and the rivets, reduce the temperature in the cutting area, thereby preventing the deformation or tool wear caused by the overheating of the rivets. At the same time, the cutting oil can wash the debris generated during the chamfering process into the inside of the oil storage tank 201, and filter out the debris under the action of the filter plate 202. The cutting oil filtered out of the debris is communicated with the quantitative box 203 under the action of the oil outlet hole, thereby realizing the recycling of the cutting oil, improving the utilization rate of the cutting oil, reducing the subsequent maintenance cost and improving the chamfering efficiency of the rivets.

[0049] When the pressure frame 204 moves downward, it contacts and squeezes the L-shaped rod 213 to move away from the quantitative box 203. The movement of the L-shaped rod 213 drives the receiving block 215 to move. The movement of the receiving block 215 contacts the convex block 214 and moves downward under its action. The downward movement of the receiving block 215 squeezes the telescopic spring rod two 217 to contract. After the telescopic spring rod two 217 contracts and then resets, the receiving block 215 contacts the convex block 214 repeatedly and generates vibration. The vibration can effectively improve the filtering effect of the filter plate 202 on the debris, avoid excessive accumulation of debris causing blockage, thereby affecting the recycling of the cutting oil, and reducing the subsequent maintenance cost. At the same time, when the rivets after chamfering fall into the inside of the oil storage tank 201, they will be screened out under the action of the material guiding rod 211, realizing the separation of the rivets and the debris, facilitating the collection of the rivets. The cutting oil on the surface of the material guiding rod 211 will be drained into the inside of the oil storage tank 201 under the action of the drainage rod 212, further realizing the utilization and recycling effect of the cutting oil and improving the processing efficiency of the rivets.
