Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and in particular to gear processing equipment and a processing method of a coal mining machine cutting assembly. Background Art

[0002] The shearer's cutting assembly is the core component of the shearer. Its primary function is to reduce the power from the electric motor and transmit it to the cutting drum for coal cutting and loading. The shearer's cutting assembly primarily consists of a rocker reduction gearbox, a cutting motor, a cooling and spraying system, and a cutting drum. These components work together to achieve efficient cutting operations. The cutting section utilizes a mechanical transmission, with the fixed reduction gearbox being the primary component. Because the drum axis is perpendicular to the motor axis, a pair of cylindrical gears are used in the cutting section's reduction gearbox. This transmission method ensures the drum receives sufficient torque and speed to meet the demands of coal mining operations.

[0003] During the processing of shearer cutting assembly gears, waste chips are a common problem. This spillage can contaminate the workplace, increasing cleaning difficulty and costs. Furthermore, the waste chips may contain hazardous substances, posing a health risk to workers. If not promptly removed, they can create a slipping hazard on the ground, increasing workplace safety risks. If the waste chips adhere to the gear surface, they can affect the gear's surface quality, and thus its transmission efficiency and service life. If the waste chips are drawn into the gear meshing area during processing, they can cause scratches or wear on the gear surface, reducing the gear's accuracy and reliability. Therefore, we propose a gear processing device and processing method for shearer cutting assembly gears to address this problem. Summary of the Invention

[0019] The present invention also provides a method for machining the gear of a coal mining machine cutting assembly, comprising the following steps:

[0020] S1: Push the two slides to drive the two positioning plates closer to each other, so that the positioning plates are retracted into the positioning frame, and then the gear blank to be processed is sleeved on the outside of the rotating column. Then, release the slides, so that the slides and positioning plates are reset under the action of the positioning springs, and then start the cylinder to drive the connecting plate, vertical shaft, square plate, positioning frame and positioning plate to move downward, so that the positioning plate is pressed against the top of the gear blank;

[0021] S2: Start the second servo motor and the third servo motor. The second servo motor drives the drive shaft and the gear shaping cutter to rotate. The third servo motor drives the rotating column and the gear blank and the gear shaping cutter to rotate synchronously through the transmission of the second driving gear and the second driven gear.

[0022] S3: Start the drive motor to rotate the shaft, and drive the shaft on the other side to rotate through the transmission of the chain and sprocket, thereby driving the two connecting columns to perform circular motion. The connecting columns drive the lifting plate to reciprocate up and down through the cooperation with the corresponding connecting plates, thereby performing gear shaping on the gear blank through the gear shaping cutter;

[0023] S4: When the lifting plate drives the pressing plate to contact the touch button, the gear shaping cutter moves to the bottom of the gear blank. At this time, the touch button transmits a signal to the controller, and the controller controls the operation of the first servo motor. The first servo motor drives the rotating drum to rotate half a circle by meshing with the first driving gear and the first driven gear, so that the gear shaping cutter rotates half a circle, so that the waste chips on its surface move to the left. Then, when the gear shaping cutter moves up, the gear shaping process is performed through the blade on the other side. The lifting plate drives the connecting rack to move in the same way while moving up and down. The connecting rack drives the transmission shaft to rotate by meshing with the transmission gear. The transmission shaft drives the cleaning shaft and the cleaning brush to accelerate the rotation through the transmission of the large pulley and the small pulley, so that the cleaning brush cleans the blade on the left side of the gear shaping cutter and sweeps off the waste chips on its surface.

[0024] S5: The sealing cylinder is driven to move up and down synchronously by the lifting plate. Due to the vertical plate and the connecting rod, the piston plate does not move up and down. Therefore, during the downward movement of the sealing cylinder, the air pressure in the area above the piston plate in the sealing cylinder increases. When the touch button is pressed, the rotating cylinder rotates and drives the rotating ring to rotate synchronously. The rotating ring drives the moving frame to move right through the contact between the arc-shaped protrusion and the abutment wheel, and stretches the connecting spring. Thereafter, the moving frame is reset under the action of the connecting spring, thereby driving the moving frame to move back and forth with the cooperation of multiple arc-shaped protrusions. The moving frame drives the baffle to move synchronously. When the baffle moves to the right, the compressed gas in the sealing cylinder is ejected through the annular plate and the vertical pipe, thereby blowing off the processing waste on the gear blank multiple times;

[0025] S6: The horizontal axis and a plurality of fan blades are driven to rotate by starting the rotary motor, thereby exhausting the air in the collection frame, so as to generate negative pressure on the top of the collection frame, thereby better achieving the absorption and collection of waste chips.

[0026] Compared with the prior art, the present invention provides a gear processing device and a processing method for a coal mining machine cutting assembly, which have the following beneficial effects:

[0027] (1) The positioning mechanism can facilitate the automatic clamping of the gear blank, and the gear shaping mechanism can be used to automatically shape the gear blank, thereby ensuring the processing efficiency;

[0028] (2) The cleaning mechanism can be set up to control the gear shaping cutter to rotate half a circle after each gear shaping is completed, so as to switch the blade of the other half circle for processing, which can not only avoid waste chips on the blade, but also help to reduce the temperature. The transmission of the connecting rack and the transmission gear can use the lifting power during the gear shaping process to drive the cleaning brush to rotate, thereby cleaning the gear shaping cutter and avoiding affecting the gear shaping work;

[0029] (3) The purging mechanism can utilize the lifting power in the gear shaping process to accumulate air pressure and then automatically spray it, so as to purge the waste on the gear blank and improve the heat dissipation efficiency to a certain extent.

[0030] The present invention is reasonably designed. Through the provided cleaning mechanism and blowing mechanism, the blade used for gear shaping can be continuously switched during gear shaping, and processing waste chips on the gear shaping cutter and the gear blank can be automatically cleaned to avoid the waste chips affecting the processing quality.

[0057] The present invention also provides a method for machining the gear of a coal mining machine cutting assembly, comprising the following steps:

[0058] S1: Push the two slides 712 to drive the two positioning plates 713 toward each other, so that the positioning plates 713 are retracted into the positioning frame 711, and then the gear blank to be processed is sleeved on the outer side of the rotating column 701. Then, release the slide 712, so that the slide 712 and the positioning plates 713 are reset under the action of the positioning spring 714, and then start the cylinder 706 to drive the connecting plate 708, the vertical shaft 709, the square plate 710, the positioning frame 711 and the positioning plates 713 to move downward, so that the positioning plates 713 are pressed against the top of the gear blank;

[0059] S2: Start the second servo motor 608 and the third servo motor 705. The second servo motor 608 drives the drive shaft 602 and the gear shaping cutter 601 to rotate. The third servo motor 705 drives the rotating column 701, the gear blank and the gear shaping cutter 601 to rotate synchronously through the transmission of the second driving gear 704 and the second driven gear 703.

[0060] S3: Start the drive motor 206 to rotate the rotating shaft 204, and drive the rotating shaft 204 on the other side through the transmission of the chain and sprocket 205, thereby driving the two connecting columns 202 to perform circular motion. The connecting columns 202 drive the lifting plate 2 to reciprocate up and down by cooperating with the corresponding connecting plates 201, thereby performing gear shaping on the gear blank through the gear shaping cutter 601;

[0061] S4: When the lifting plate 2 drives the pressing plate to contact the touch button 410, the gear shaping cutter 601 moves to the bottom of the gear blank. At this time, the touch button 410 transmits a signal to the controller 15, and the controller 15 controls the first servo motor 607 to operate. The first servo motor 607 drives the rotating drum 604 to rotate half a circle by meshing with the first driving gear 606 and the first driven gear 605, so that the gear shaping cutter 601 rotates half a circle, so that the waste chips on its surface move to the left, and then the gear shaping cutter 601 is rotated half a circle. When the cutter 601 moves upward, the gear shaping process is performed through the blade on the other side, and the lifting plate 2 drives the connecting rack 407 to move in the same manner as the reciprocating movement up and down. The connecting rack 407 drives the transmission shaft 401 to rotate by meshing with the transmission gear 406. The transmission shaft 401 drives the cleaning shaft 402 and the cleaning brush 403 to accelerate the rotation through the transmission of the large pulley 405 and the small pulley 404, so that the cleaning brush 403 cleans the blade on the left side of the gear shaping cutter 601 and sweeps off the waste chips on its surface.

[0062] S5: The sealing cylinder 8 is driven to move up and down synchronously by the lifting plate 2. Due to the vertical plate 3 and the connecting rod 5, the piston plate 502 does not move up and down. As the sealing cylinder 8 moves downward, the air pressure in the area above the piston plate 502 in the sealing cylinder 8 increases. When the touch button 410 is pressed, the rotating cylinder 604 rotates to drive the rotating ring 906 to rotate synchronously. The rotating ring 906 drives the moving frame 9 to move right through the contact between the arc-shaped protrusion and the abutment wheel 904, and stretches the connecting spring 903. Thereafter, the moving frame 9 is reset under the action of the connecting spring 903, thereby driving the moving frame 9 to move back and forth left and right under the cooperation of multiple arc-shaped protrusions. The moving frame 9 drives the baffle 901 to move synchronously. When the baffle 901 moves to the right, the compressed gas in the sealing cylinder 8 is ejected through the annular plate 902 and the vertical pipe 501, thereby blowing the processing waste on the gear blank multiple times;
