Description

Technical Field

[0001] The invention relates to the technical field of grinding, in particular to an edge and corner grinding device for cold precision forging gears with a multi-directional grinding function. Background Art

[0002] After the gears are manufactured, they need to be polished to ensure their normal use. This is usually done manually, with workers using small grinders to polish the gears. This method is time-consuming and labor-intensive. Currently, a grinding device dedicated to gears is used to polish the gears. Although this can solve some of the above problems, it also has certain problems. During the grinding process, debris falls to various locations, making it very difficult to clean. In addition, the fixture needs to be frequently replaced during grinding to adjust the position of the gears. Therefore, the existing gear grinding devices have the following main problems: (1) The debris is not collected, which can easily cause personal injury. (2) The fixture needs to be frequently replaced to flip the gears, which is time-consuming and labor-intensive. Summary of the invention

[0003] The object of the present invention is to provide an edge and corner grinding device for cold precision forged gears with a multi-directional grinding function to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: comprising a frame, an electric cylinder is installed on the frame, a grinding cover is installed on one side of the electric cylinder, a grinding plate is installed in the grinding cover, a visual sensor is installed on one side of the grinding cover, a dust cover is installed below the grinding cover, a brush plate, a filter membrane and a first spring are installed in the dust cover, a fixed plate is installed below the visual sensor, a moving plate is installed on one side of the fixed plate, a rotating plate is installed on the moving plate, a clamping cylinder is installed on the rotating plate, and the clamping cylinder clamps and positions the gear;

[0005] The grinding plate grinds the gears, the dust cover collects debris, the brush plate cleans the filter membrane, and the visual sensor detects the effect of the gear grinding.

[0006] The fixed plate is installed on the frame, the movable plate and the fixed plate are slidably connected, the movable plate and the fixed plate are connected by a second spring, the second spring is electrically connected to the control system, the rotating plate is rotatably installed on the movable plate, the rotating plate and the movable plate are connected by a third spring, and the third spring is electrically connected to the control system.

[0007] It includes a negative pressure pump and a filtering device, the dust hood is hollow inside, the brush plate is slidably installed on the dust hood, the brush plate and the dust hood are connected by a first spring, the first spring is electrically connected to a control system, the filter membrane is located on one side of the brush plate, a brush is provided on the brush plate close to the filter membrane side, a first chamber is formed between the filter membrane and the dust hood, the negative pressure pump is installed on a frame, the filtering device is connected to the first chamber through a pipeline, and the negative pressure pump is connected to the filtering device through a pipeline.

[0008] The telescopic rod of the electric cylinder is rotatably mounted with the output shaft of the adjusting motor through a bearing, the adjusting motor is slidably mounted on the frame, and the polishing cover is mounted on the output shaft of the adjusting motor.

[0009] It includes a liquid supply mechanism, a plurality of injection holes are arranged on the polishing cover, the liquid supply mechanism is connected with the injection holes through pipelines, a one-way valve is installed in the injection holes, a rotating motor is installed in the polishing cover, the polishing plate is installed on the output shaft of the rotating motor, and the rotating motor and the regulating motor are both equipped with built-in pressure sensors and encoders.

[0010] Press the start button on the control panel to start the device. The control system energizes the second spring and the third spring. The magnetic field between each turn of the second spring attracts each other, and the magnetic field compresses the second spring, shortens the second spring, and the second spring pulls the movable plate to move, and the movable plate drives the rotating plate to move. Similar to the second spring, since the rotating plate is rotatably installed on the movable plate, the third spring pulls the rotating plate from a vertical state to a horizontal state, and the clamping cylinder and its internal components on the rotating plate follow the rotating plate to change from a vertical state to a horizontal state.

[0011] The gears to be polished are placed on the outside of multiple clamping plates, and the first sensor on the clamping plates feeds back data to the control system. The pressure pump works, and the first control valve on the pipeline between the pressure pump and the pressure hole is opened. The pressure pump pressurizes the external air and transports it to the pressure hole through the pipeline. The pressurized air pushes the multiple clamping plates to move radially outward, and the multiple clamping plates stretch the springs at the same time. The multiple clamping plates clamp the gears in place. When the gears are clamped in place, the first sensor feeds back data to the control system, and the first control valve on the pipeline between the pressure pump and the pressure hole is closed, and the multiple clamping plates remain in a clamped state. The pressure pump is prior art.

[0012] After multiple clamping plates position the gears, the control system cuts off the power to the second spring. Under the action of its own elastic force, the distance between the two ends of the second spring gradually increases, and the second spring pushes the moving plate to move in the opposite direction until the clamping cylinder on the rotating plate is concentric with the grinding plate.

[0013] When the clamping cylinder and the grinding plate are concentric, the electric cylinder drives the grinding cover to move downward, and the grinding cover drives the rotating motor and the grinding plate to move downward. After the grinding plate contacts the gear, the electric cylinder stops working and the rotating motor starts working. The rotating motor drives the grinding plate to rotate, and the grinding plate grinds the surface and corners of the gear.

[0014] When the gear is being polished, the liquid supply mechanism transports the coolant to the polishing cover through the pipeline, and the coolant is sprayed outward through the injection hole, and the coolant is sprayed on the gear surface to cool the gear. The negative pressure pump and the filter device work, and the polished debris is adsorbed on the filter membrane, and the coolant passes through the filter membrane into the filter device. After being filtered by the filter device, it can be used again. The control system continuously energizes and de-energizes the first spring, and a mutually attractive magnetic field is generated between each turn of the first spring. The first spring will shrink, and the first spring will pull the brush plate to move. After that, the first spring is de-energized, and the first spring gradually becomes longer under the action of its own elastic force. The first spring pushes the brush plate to move in the opposite direction. Therefore, when the first spring is continuously energized and de-energized, the brush plate reciprocates. During the reciprocating movement, the brush plate brushes off the debris on the filter membrane to ensure the filtering effect of the filter membrane and prevent the filter membrane from being blocked. The liquid supply mechanism, the negative pressure pump and the filter device are prior art.

[0015] When the position of the gear needs to be adjusted, the control system cuts off the power to the third spring. Under the action of its own elastic force, the distance between the two ends of the third spring gradually becomes longer, and the third spring pushes the rotating plate from a horizontal state to a vertical state. The clamping cylinder, clamping plate and gear on the rotating plate are all turned from a horizontal state to a vertical state to achieve a change in direction. The adjusting motor drives the grinding cover to rotate to a set angle. The set angle is set in advance by the staff through the control panel according to needs. The grinding cover drives the grinding plate to rotate to the set angle. Afterwards, similar to the above grinding, the rotating motor drives the grinding plate to rotate for grinding. At the same time, the rotating motor and the grinding plate are connected by a snap-on structure, and the staff can replace the corresponding grinding plate according to actual needs.

[0016] After the gear is polished by the polishing plate, the control system energizes the second spring. Similarly to the above, the moving plate, rotating plate, clamping cylinder and gear on the second spring move, and the gear is moved under the visual sensor. The visual sensor detects the effect of polishing and feeds the data back to the control system.

[0017] When the visual sensor detects that the grinding effect is qualified, the first control valve on the pipeline between the pressure pump and the pressure hole is opened, and the first control valve releases the pressurized air and discharges it to the outside air. The springs on one side of the multiple clamping plates are released, and the springs pull the clamping plates to move radially inward. At this time, the multiple clamping plates loosen the gears, and then the gears are removed by the robot or the staff and placed on the conveyor line for the next step of processing;

[0018] When the visual sensor detects that the polishing effect is unsatisfactory, the position where the polishing effect is unsatisfactory will be polished again in the same way as above. The control system will coordinate the data of the visual sensor and the data of the encoder in the rotating motor to polish the position where the polishing effect is unsatisfactory again.

[0019] The contraction degree of the first spring, the second spring and the third spring is determined by the magnitude of the current passed through. The greater the current passed through, the greater the contraction. Therefore, the control system can adjust the contraction distance of the third spring by adjusting the magnitude of the current passed through the third spring, and then adjust the rotation angle of the rotating plate to achieve the angle adjustment of the gear, and support the rotating plate through the supporting device, and then adjust the angle of the grinding cover and the grinding plate by adjusting the motor. The supporting device is a prior art to adapt to different usage scenarios.

[0020] It includes a pressure pump, a plurality of clamping plates are installed on the clamping cylinder through spring sliding, a first sensor is arranged on one side of the clamping plates, the first sensor is electrically connected to the control system, a pressure chamber is formed between the plurality of clamping plates and the clamping cylinder, a pressure hole is arranged on the clamping cylinder close to the pressure chamber, the pressure hole is connected to the pressure pump through a pipeline, the pressure pump is installed on a frame, a first control valve is installed in the pipeline connected to the pressure pump and the negative pressure pump, and the first control valve is electrically connected to the control system.

[0021] The invention comprises a manipulator and a conveyor line. The manipulator is installed on a frame and is located at one side of the conveyor line. The manipulator transports the polished gears to the conveyor line.

[0022] The utility model comprises a supporting device, wherein the supporting device is installed between the rotating plate and the moving plate, and the supporting device supports the rotating plate.

[0023] The grinding plate and the output shaft of the rotating motor are connected via a snap-fit ​​structure, and the clamping plate is made of nylon.

[0024] A control panel is installed on the frame, and a control system is arranged inside the control panel.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0026] 1. Collect the debris to ensure a clean working environment. The debris after grinding is adsorbed on the filter membrane, and the coolant passes through the filter membrane into the filter device. After being filtered by the filter device, it can be used again. The control system continuously energizes and de-energizes the first spring. A magnetic field of mutual attraction is generated between each turn of the first spring. The first spring will shrink, and the first spring will pull the brush plate to move. The first spring is de-energized. Under the action of its own elastic force, the first spring gradually becomes longer, and the first spring pushes the brush plate to move in the opposite direction. Therefore, when the first spring is continuously energized and de-energized, the brush plate moves back and forth. During the reciprocating movement, the brush plate brushes off the debris on the filter membrane to avoid personal injury to the staff when it is thrown out.

[0027] 2. No need to frequently replace the fixture, which improves work efficiency. The control system cuts off the power to the third spring. Under the action of its own elastic force, the distance between the two ends of the third spring gradually increases, and the third spring pushes the rotating plate from a horizontal state to a vertical state. The clamping cylinder, clamping plate and gear on the rotating plate are all turned from a horizontal state to a vertical state to achieve a change in direction. The grinding cover drives the grinding plate to rotate to the set angle, and the rotating motor drives the grinding plate to rotate for grinding. The rotating motor and the grinding plate are connected by a buckle structure, and the staff can replace the corresponding grinding plate according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

It includes a manipulator and a conveying line, and the manipulator is installed on the frame 11. The manipulator is located on one side of the conveying line, and the manipulator transports the polished gear 15 to the conveying line, and includes a supporting device, and the supporting device is installed between the rotating plate 181 and the movable plate 18, and the supporting device supports the rotating plate 181.

[0044] The working principle of the present invention is as follows: the start button on the control panel 1 is pressed, the device is started, and the control system energizes the second spring 17 and the third spring 171. The magnetic field between each turn of the second spring 17 attracts each other, and the magnetic field compresses the second spring 17, and the second spring 17 shortens. The second spring 17 pulls the movable plate 18 to move, and the movable plate 18 drives the rotating plate 181 to move. Similar to the second spring 17, since the rotating plate 181 is rotatably installed on the movable plate 18, the third spring 171 pulls the rotating plate 181 from a vertical state to a horizontal state, and the clamping cylinder 16 and its internal components on the rotating plate 181 follow the rotating plate 181 to change from a vertical state to a horizontal state.

[0045] The gear 15 to be polished is placed on the outside of multiple clamping plates 161, and the first sensor on the clamping plates 161 feeds back data to the control system. The pressure pump works, and the first control valve on the pipeline between the pressure pump and the pressure hole 162 is opened. The pressure pump pressurizes the external air and transports it to the pressure hole 162 through the pipeline. The pressurized air pushes the multiple clamping plates 161 to move radially outward, and the multiple clamping plates 161 stretch the springs at the same time. The multiple clamping plates 161 clamp the gear 15 into position. When the gear 15 is clamped into position, the first sensor feeds back data to the control system, and the first control valve on the pipeline between the pressure pump and the pressure hole 162 is closed, and the multiple clamping plates 161 remain in a clamped state. The pressure pump is the prior art.

[0046] After the multiple clamping plates 161 position the gear 15, the control system cuts off the power to the second spring 17. Under the action of its own elastic force, the distance between the two ends of the second spring 17 gradually increases, and the second spring 17 pushes the moving plate 18 to move in the opposite direction until the clamping cylinder 16 on the rotating plate 181 and the grinding plate 211 are concentric.

[0047] When the clamping cylinder 16 and the grinding plate 211 are concentric, the electric cylinder 2 drives the grinding cover 21 to move downward, and the grinding cover 21 drives the rotating motor 23 and the grinding plate 211 to move downward. After the grinding plate 211 contacts the gear 15, the electric cylinder 2 stops working, and the rotating motor 23 works. The rotating motor 23 drives the grinding plate 211 to rotate, and the grinding plate 211 grinds the surface and corners of the gear 15.

[0048] When the gear 15 is being polished, the liquid supply mechanism delivers the coolant to the polishing cover 21 through the pipeline, and the coolant is sprayed outward through the spray hole, and the coolant is sprayed on the surface of the gear 15 to cool the gear 15. The negative pressure pump and the filter device work, and the polished debris is adsorbed on the filter membrane 141, and the coolant passes through the filter membrane 141 and enters the filter device. After being filtered by the filter device, it can be used again. The control system continuously powers on and off the first spring 143, and a magnetic field of mutual attraction is generated between each turn of the first spring 143, and the first spring 143 will shrink. The first spring 143 contracts and pulls the brush plate 142 to move. After that, the first spring 143 is powered off and the first spring 143 gradually lengthens under its own elastic force. The first spring 143 pushes the brush plate 142 to move in the opposite direction. Therefore, the brush plate 142 reciprocates when the first spring 143 is continuously powered on and off. During the reciprocating movement, the brush plate 142 brushes off the debris on the filter membrane 141 to ensure the filtering effect of the filter membrane 141 and prevent the filter membrane 141 from being blocked. The liquid supply mechanism, the negative pressure pump and the filtering device are prior art.

[0049] When the position of the gear 15 needs to be adjusted, the control system cuts off the power to the third spring 171. Under the action of its own elastic force, the distance between the two ends of the third spring 171 gradually becomes longer, and the third spring 171 pushes the rotating plate 181 from a horizontal state to a vertical state. The clamping cylinder 16, the clamping plate 161 and the gear 15 on the rotating plate 181 are all changed from a horizontal state to a vertical state to achieve a direction change. The adjusting motor 22 drives the grinding cover 21 to rotate to a set angle. The set angle is set in advance by the staff through the control panel 1 according to the needs. The grinding cover 21 drives the grinding plate 211 to rotate to the set angle. Afterwards, similar to the above grinding, the rotating motor 23 drives the grinding plate 211 to rotate for grinding. At the same time, the rotating motor 23 and the grinding plate 211 are connected by a snap-on structure. The staff can replace the corresponding grinding plate 211 according to actual needs.

[0050] After the gear 15 is polished by the polishing plate 211, the control system energizes the second spring 17. Similarly to the above, the moving plate 18, the rotating plate 181, the clamping cylinder 16 and the gear 15 on the second spring 17 move, and the gear 15 is moved under the visual sensor 13. The visual sensor 13 detects the effect of polishing and feeds back the data to the control system.

[0051] When the visual sensor 13 detects that the grinding effect is qualified, the first control valve on the pipeline between the pressure pump and the pressure hole 162 is opened, and the first control valve releases the pressurized air and discharges it to the outside air. The springs on one side of the multiple clamping plates 161 are released, and the springs pull the clamping plates 161 to move radially inward. At this time, the multiple clamping plates 161 loosen the gear 15, and then the gear 15 is removed by a robot or a staff member and placed on the conveyor line for the next step of processing;

[0052] When the visual sensor 13 detects that the polishing effect is unsatisfactory, the position where the polishing effect is unsatisfactory will be polished again in the same manner as above. The control system coordinates the data of the visual sensor 13 and the data of the encoder in the rotating motor 23 to polish the position where the polishing effect is unsatisfactory again.

[0053] The contraction degree of the first spring 143, the second spring 17 and the third spring 171 is determined by the magnitude of the current passed through. The greater the current passed through, the greater the contraction. Therefore, the control system can adjust the contraction distance of the third spring 171 by adjusting the magnitude of the current passed through the third spring 171, and then adjust the rotation angle of the rotating plate 181 to achieve angle adjustment of the gear 15, and support the rotating plate 181 through a supporting device, and then adjust the angle of the grinding cover 21 and the grinding plate 211 by adjusting the motor 22 to achieve multi-directional grinding of the gear 15. The supporting device is a prior art to adapt to different usage scenarios.
