Description

Technical Field

[0001] The present invention relates to the technical field of intelligent milling processing, and more specifically, the present invention relates to a chamfering device for processing nuts used in engines. Background Art

[0002] In the intelligent manufacturing equipment industry, for the milling device of the chamfering machine used for processing special work-piece nuts of engines, its main function is reflected in the function of efficient production. The chamfering machine can achieve automated processing, reduce manual intervention, and improve production efficiency. At the same time, due to the precise planning of the tool path, unnecessary processing time and material waste are reduced, further reducing production costs.

[0003] In the existing publicly disclosed technical literature, the patent with the Chinese patent publication number CN118417610A discloses a chamfering machine for processing single-eccentric self-locking nuts. This technology mainly uses a moving mechanism to drive the milling cutter to move to the position where the eccentric nut hole is located; this device can quickly determine the position of the eccentric nut hole, and then automatically adjust the milling cutter to the corresponding position, thereby effectively improving the convenience of chamfering the eccentric nut, and further improving the efficiency of chamfering the eccentric nut. However, this technology still has the following defects.

[0004] In the intelligent manufacturing equipment industry, when chamfering and milling special work-piece nuts of engines on a machine tool, first place the special work-piece nuts of the engine at the designated milling position and then fix them. If the special work-piece nuts of the engine are offset during placement and then directly fixed, it will cause the chamfering position to be offset during the chamfering of the special work-piece nuts of the engine, resulting in poor machining accuracy of the special work-piece nuts of the engine. It is difficult to synchronously and accurately proofread the horizontal and vertical positions when placing the special work-piece nuts of the engine, and at the same time, it is difficult to fix the vertical position synchronously when proofreading the special work-piece nuts of the engine is completed. As a result, when milling the special work-piece nuts of the engine, it is difficult to achieve intelligent automatic precise proofreading and rapid precise fixing at the same time, and the machining accuracy of the special work-piece nuts of the engine is poor. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: A chamfering device for processing nuts used in engines, including a machine tool milling table, a socket block, a groove column, and a controller.

A calibration groove roller is fixedly installed on the outer wall of the support column. A distance sensor is fixedly connected to the inside of the calibration groove roller. A timely calibration chamfering component is provided at the top of the socket block.

[0007] Preferably, a fixed connection is provided between the output end of the servo motor and the groove column. The servo motor is used to drive the groove column to rotate. Both of the two threaded sleeve blocks are slidably connected to the groove column. Both the servo motor and the calibration motor are electrically connected to a controller. The distance sensor is electrically connected to the servo motor. The controller is fixed on one side of the machine tool milling table. A support bar is fixedly connected to the top of the servo motor. A support rod is fixedly installed at one end of the support bar. Fixed connections are provided between the machine tool milling table and the socket block and the support rod respectively.

[0008] When this technology is in use, the calibration motor drives the linkage screw to rotate. The linkage screw drives the two threaded sleeve blocks to approach each other under the action of the thread driving force. One threaded sleeve block moves left, and the other threaded sleeve block moves right. The groove bar drives the support column to move left. The calibration groove roller drives the distance sensor to approach the right side of the engine nut, and the other distance sensor approaches the left side of the engine nut. When the distance value sensed by the distance sensor is one centimeter set by the controller, the outer wall of the calibration groove roller fits on the right side of the engine nut, and the outer wall of the other distance sensor fits on the left side of the engine nut. The servo motor drives the groove column to rotate clockwise by 180 degrees. The groove column rotates clockwise by 180 degrees inside the socket block. The linkage screw drives the two threaded sleeve blocks to rotate clockwise by 180 degrees. The groove bar drives the support column to rotate clockwise by 180 degrees. The calibration groove roller that fits on the right side of the engine nut rotates clockwise by 180 degrees, and the other calibration groove roller that fits on the left side of the engine nut rotates clockwise by 180 degrees.

A piezoelectric cylinder is fixedly connected to the upper surface of the sleeve frame. The piezoelectric cylinder is electrically connected to the controller. A pressing strip is fixedly installed at the output end of the piezoelectric cylinder. One end of the socket block is fixedly connected to a positioning strip. An engine nut is slidably connected to the inner wall of the positioning strip. The positioning strip is fixedly connected to the machine tool milling table. A sliding sleeve block is fixedly installed at the top end of the inner wall of the positioning strip. A support block is arranged on one side of the sliding sleeve block. The support block is fixedly connected to the positioning strip. A convex strip column is slidably connected to the inner wall of the sliding sleeve block.

The pressure sensor is fixedly connected to the support block. The pressure sensor is electrically connected to the controller. The outer wall of the output end of the piezoelectric cylinder is slidably connected to the sleeve frame. The sleeve frame is used to support the piezoelectric cylinder. The center point of the linkage column and the center point of the rubber pressing column are on the same horizontal line. The vertical cross-sectional shapes of the linkage column and the rubber pressing column are both circular. The outer wall of the guiding head is chamfered. The outer wall of the guiding head is a smooth surface.

[0010] When this technology is in use, during the process that the calibration groove roller rotates clockwise by 180 degrees, the calibration groove roller presses the guiding head. The guiding head drives the linkage column to move leftward. The convex strip column slides leftward along the inner wall of the sliding sleeve block. The rubber pressing column presses on the sensing end of the pressure sensor. When the pressure sensor senses the pressure value, it is known that the calibration groove roller has just completed the horizontal and vertical calibration operations on the engine nut. The piezoelectric cylinder drives the pressing strip to move downward, so that the engine nut is fixed inside the positioning strip. At the same time when the two calibration groove rollers complete the two-way calibration of the engine nut, the pressing strip can fix the engine nut simultaneously.

[0011] Preferably, docking electric cylinders are fixedly connected to the upper surface of the machine tool milling table and near both ends thereof. A distributed docking milling component is installed at the output end of the docking electric cylinder. The distributed docking milling component includes a socket sliding plate, two tracks, a rotating shaft, a rotating motor, a bracket, a plurality of chamfering cutters and a protective cover.

The two tracks are symmetrically arranged with respect to the docking electric cylinder. Both the socket sliding plate and the rotating motor are fixedly connected to the bracket, and the bracket is used to support the rotating motor.

[0013] When the present technology is in use, the two docking electric cylinders respectively push the two socket sliding plates to approach each other. The socket sliding plate drives the bracket to move, the rotating motor makes the rotating shaft move, and the rotating shaft drives the plurality of chamfering cutters to approach and contact the inner wall position on the right side of the engine nut, while the plurality of chamfering cutters on the other rotating shaft approach and contact the inner wall position on the left side of the engine nut. By starting the two rotating motors respectively through the controller, the plurality of chamfering cutters and the engine nut achieve contact milling chamfering.

[0014] The technical effects and advantages of the present invention:

[0015] 1. Through the two-way synchronous alignment chamfering mechanism of the present invention, the alignment motor drives the linkage screw to rotate. The linkage screw drives the two threaded sleeve blocks to approach each other under the action of the thread driving force. The alignment groove roller drives the distance sensor to approach the right side of the engine nut, and the other distance sensor approaches the left side of the engine nut. The two alignment groove rollers can accurately align the horizontal position of the engine nut, and at the same time can also accurately align the vertical position of the engine nut. At the end of the alignment, the engine nut can be intelligently and automatically accurately fixed. When the engine nut is being milled, it can intelligently and automatically accurately align the horizontal and vertical positions of the engine nut, and quickly and accurately fix the engine nut at the end of the alignment, greatly improving the accuracy of the milling process of the engine nut.

[0016] 2. The present invention adopts a timely alignment chamfering component. During the process of the alignment groove roller rotating 180 degrees clockwise, the alignment groove roller will rotate and squeeze the guiding head. The alignment groove roller squeezes the guiding head, and the guiding head moves leftward under the action of the guiding force. The linkage column drives the convex strip column to move leftward, and the convex strip column drives the rubber pressing column to move leftward and squeeze. When the pressure sensor senses the pressure value, it is known that the alignment groove roller has just completed the horizontal and vertical alignment operations on the engine nut. Immediately start the pressing electric cylinder through the controller, and the engine nut is fixed inside the positioning strip. At the end of the alignment, the engine nut can be intelligently and automatically accurately fixed, greatly improving the accuracy of the milling process of the engine nut.

[0017] 3. The present invention adopts a distributed butt - milling component. Two docking cylinders respectively push two socket - sliding plates to approach each other. The socket - sliding plates drive the bracket to move. The rotating shaft drives multiple chamfering cutters to approach and contact the inner wall position on the right side of the engine nut, while multiple chamfering cutters on the other rotating shaft approach and contact the inner wall position on the left side of the engine nut, enabling the multiple chamfering cutters on the left side and the multiple chamfering cutters on the right side to achieve distributed butt - milling of both inner sides of the engine nut, thus avoiding the problem of milling offset of the engine nut.

Both the socket sliding plate 28 and the rotating motor 31 are fixedly connected to the bracket 32. The bracket 32 is used to support the rotating motor 31.

[0037] The working principle of the chamfering device for machining nuts for the engine of the present invention is as follows:

[0038] First, when the present invention is placed, the engine nut 19 is placed in the inner wall of the positioning strip 18. The machine tool milling table 1 supports the positioning strip 18, and the positioning strip 18 supports the engine nut 19. At the same time, the machine tool milling table 1 supports the support rod 14, the support rod 14 supports the socket block 2, and the support rod 14 also supports the support strip 13 to increase the stability of the support strip 13. The support strip 13 supports the servo motor 4 to increase the stability of the servo motor 4.

[0039] Secondly, when the two-way synchronous calibration chamfering is carried out in the present invention, the calibration motor 7 is started through the controller 12. The calibration motor 7 drives the linkage screw rod 5 to rotate. The linkage screw rod 5 rotates inside the groove column 3. The linkage screw rod 5 drives the two threaded sleeve blocks 6 to approach each other under the action of the threaded transmission force. At the same time, both of the two threaded sleeve blocks 6 slide close to each other along the inner wall of the groove column 3. One threaded sleeve block 6 moves leftward, and the other threaded sleeve block 6 moves rightward. The threaded sleeve block 6 drives the groove bar 8 to move leftward. The groove bar 8 drives the support column 9 to move leftward. The support column 9 causes the calibration groove roller 10 to move leftward. The calibration groove roller 10 drives the distance sensor 11 to approach the right side surface of the engine nut 19, and the other distance sensor 11 approaches the left side surface of the engine nut 19. The distance between the distance sensor 11 and the engine nut 19 is sensed by the distance sensor 11. When the distance value sensed by the distance sensor 11 is one centimeter set by the controller 12, the outer wall of the calibration groove roller 10 is attached to the right side surface of the engine nut 19, and the outer wall of the other distance sensor 11 is attached to the left side surface of the engine nut 19. In this way, the lateral offset position of the engine nut 19 is accurately calibrated.

[0040] Then the servo motor 4 is started. The servo motor 4 drives the groove column 3 to rotate clockwise by 180 degrees. In this way, the groove column 3 drives the linkage screw rod 5 to rotate clockwise by 180 degrees. The groove column 3 rotates clockwise by 180 degrees inside the socket block 2. The linkage screw rod 5 drives the two threaded sleeve blocks 6 to rotate clockwise by 180 degrees. The two threaded sleeve blocks 6 respectively drive the two groove bars 8 to rotate clockwise by 180 degrees. The groove bar 8 drives the support column 9 to rotate clockwise by 180 degrees. The support column 9 drives the calibration groove roller 10 to rotate clockwise by 180 degrees. The calibration groove roller 10 attached to the right side surface of the engine nut 19 rotates clockwise by 180 degrees, and the other calibration groove roller 10 attached to the left side surface of the engine nut 19 rotates clockwise by 180 degrees. The two calibration groove rollers 10 can accurately calibrate the lateral position of the engine nut 19, and at the same time can also accurately calibrate the vertical position of the engine nut 19. In this way, the calibration groove roller 10 can slide horizontally from top to bottom on the positioning strip 18 to calibrate the processing position.

[0041] Then, when the present invention performs timely chamfering alignment, during the process that the alignment grooved roller 10 rotates clockwise by 180 degrees, the alignment grooved roller 10 will rotate and squeeze the guiding head 24. Since the outer wall of the guiding head 24 is a chamfered surface, when the alignment grooved roller 10 squeezes the guiding head 24, the guiding head 24 moves leftward under the action of the guiding force. The guiding head 24 drives the linkage column 23 to move leftward, the linkage column 23 drives the ribbed column 22 to move leftward, and the ribbed column 22 moves and slides leftward along the inner wall of the sliding sleeve block 20. The ribbed column 22 drives the rubber pressing column 25 to move leftward to squeeze. The rubber pressing column 25 squeezes on the sensing end of the pressure sensor 26. The pressure sensor 26 is supported by the support block 21, and the pressure sensor 26 realizes pressure sensing on the rubber pressing column 25. When the pressure sensor 26 senses the pressure value, it is known that the alignment grooved roller 10 just completes the horizontal and vertical alignment operations on the engine nut 19. At the same time, the controller 12 immediately starts the lower piezoelectric cylinder 16. The lower piezoelectric cylinder 16 drives the pressing strip 17 to move downward. The pressing strip 17 squeezes on the top of the engine nut 19, so that the engine nut 19 is fixed inside the positioning strip 18. When the two alignment grooved rollers 10 complete the two-way alignment of the engine nut 19, the pressing strip 17 can fix the engine nut 19 at the same time, avoiding the problem of offset during the fixing process of the engine nut 19. When the engine nut 19 is milled, it can be intelligently and automatically aligned in time and fixed quickly, avoiding the problem of offset in the horizontal and vertical positions.

[0042] Finally, when the present invention performs distributed docking milling, the controller 12 starts two docking electric cylinders 27. The two docking electric cylinders 27 respectively push two socket sliding plates 28 to approach each other, and the socket sliding plates 28 slide on the track 29. At the same time, the socket sliding plates 28 drive the bracket 32 to move, the bracket 32 drives the rotary motor 31 to move, the rotary motor 31 moves the rotating shaft 30, and the rotating shaft 30 drives a plurality of chamfering cutters 33 to approach and contact the position of the right inner wall of the engine nut 19, while a plurality of chamfering cutters 33 on another rotating shaft 30 approach and contact the position of the left inner wall of the engine nut 19. The controller 12 respectively starts the two rotary motors 31. The rotary motor 31 drives the rotating shaft 30 to rotate, the rotating shaft 30 drives a plurality of chamfering cutters 33 to rotate, and the plurality of chamfering cutters 33 contact and mill the chamfer of the engine nut 19, enabling the plurality of chamfering cutters 33 on the left and the plurality of chamfering cutters 33 on the right to perform distributed docking milling on the two sides inside the engine nut 19. At the same time, the protective cover 34 protects the debris.
