Therefore, it is very necessary to design a multi-axis tool processing equipment for holes. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-axis tool processing equipment for holes to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A multi-axis tool processing equipment for holes includes a support frame, the front end of the support frame is fixedly connected with a processing end shell, both the left and right sides of the processing end shell are fixedly connected with adjusting shaft seats, the top surface of the processing end shell is fixedly connected with a top cover, a drilling mechanism is arranged inside the processing end shell, a firmware protection mechanism is arranged below the processing end shell, a ventilation and lubrication mechanism is arranged at the top end of the top cover, an adjusting worm is rotatably connected inside the processing end shell, and a mounting plate is fixedly connected to the top surface of the top cover;

[0006] The drilling mechanism includes a slider plate fixedly connected inside the support frame. A rotating shaft slider is slidably connected to the top surface of the slider plate. A transmission sprocket is rotatably connected to the bottom surface of the rotating shaft slider. A chain is arranged outside the transmission sprocket. A socket cylinder is fixedly connected to the front side surface of the rotating shaft slider. An inner sliding cylinder is slidably connected to one end of the socket cylinder away from the rotating shaft slider. A short fixed shaft is fixedly connected to the bottom surface of the slider plate near the processing end shell. A turbine shaft cylinder is rotatably connected to the outer side surface of the short fixed shaft. A deflection grooved wheel is fixedly connected to the outer side surface of the turbine shaft cylinder. Six inclined push grooves are formed on the upper surface of the deflection grooved wheel.

[0007] According to the above technical solution, the bottom end of the short fixed shaft is fixedly connected with an adjusting groove disc. Six slider grooves are formed on the upper surface of the adjusting groove disc. A groove-following block is slidably connected inside each slider groove. A pressure-receiving cylinder is fixedly connected to the top surface of the groove-following block. A drill rod is rotatably connected inside the pressure-receiving cylinder. A drilling sprocket is fixedly connected to the top end of the drill rod.

[0008] According to the above technical solution, a return spring is arranged inside the inner sliding cylinder, and both ends of the return spring are fixedly connected to the inner sliding cylinder and the socket cylinder respectively. One end of the inner sliding cylinder away from the socket cylinder is fixedly connected to the slider plate. The drilling sprocket is meshed with the chain. When the hydraulic rod connected to the mounting plate extends downward, the mounting plate moves downward and pushes the support frame to move downward together. The external motor on the adjusting shaft seat rotates to drive the connected adjusting worm to rotate, so that the adjusting worm drives the meshed turbine shaft cylinder. The turbine shaft cylinder rotates to drive the connected deflection grooved wheel to rotate, so that the deflection grooved wheel pushes the pressure-receiving cylinder to be pressurized through the inclined push groove, so that the pressure-receiving cylinder drives the connected groove-following block to slide along the slider groove after being pressurized, and the slider groove moves to adjust the position of the drill rod connected to the pressure-receiving cylinder. When the groove-following block slides along the slider groove close to the center of the adjusting groove disc, the return spring in the inner sliding cylinder releases elastic force to push the socket cylinder away from the processing end shell, and makes the rotating shaft slider connected to the socket cylinder slide along the slider plate. During this process, the external motor on the rotating shaft slider rotates to drive the transmission sprocket to rotate, so that the chain connected to the outside of the transmission sprocket drives other meshed drilling sprockets to rotate. The drilling sprocket rotates to drive the connected drill rod to rotate. The drill rod moves downward together with the processing end shell connected to the support frame to perform simultaneous drilling on multiple positions of the part. At the same time, the position of the groove-following block on the adjusting groove disc is adjusted by the rotation of the deflection grooved wheel. While improving the drilling efficiency of the part, the drilling position of the drill rod is adjusted to drill different sizes of parts or different positions, improving the adaptability range and flexibility of part processing.

[0009] According to the above technical solution, the firmware protection mechanism includes a cross bar, which is slidably connected inside the short fixed shaft. A pressing disc is fixedly connected to the bottom end of the cross bar. Six reserved grooves are formed on the top surface of the pressing disc. Elastic retaining bars are symmetrically distributed on both sides inside each reserved groove. Six chute rods are slidably connected to the bottom surface of the pressing disc. A spring piece is fixedly connected to the end of the chute rod close to the pressing disc, and both ends of the spring piece are fixedly connected to the chute rod and the pressing disc respectively.

[0010] According to the above technical solution, a correction inclined rod is fixedly connected to the end of the chute rod away from the pressing disc. Convex strips are fixedly connected to both sides of the chute rod. A plurality of pressing strips are fixedly connected to the bottom surface of the pressing disc.

[0011] According to the above technical solution, the inside of the pressing disc is of a hollow structure. The pressing strips are located at the bottom side edge of the reserved groove. When the mounting plate moves downward, the short fixed shaft pushes the pressing disc to contact the top surface of the part through the connected cross bar. As the mounting plate continues to move downward, the cross bar slides upward along the short fixed shaft. At this time, the correction inclined rod connected to the pressing disc contacts the edge of the circular part, and the edge of the circular part is extruded by the inclined surface of the correction inclined rod, so that six places on the edge of the circular part are all pressed by the correction inclined rod. At this time, the connected chute rod is driven by the pressure of the correction inclined rod to slide along the pressing disc and pull the spring piece, thereby preventing the edge of the circular part from being deformed due to excessive pressure, and enabling the pressed circular part to move to the center of the pressing disc after being pressed by the correction inclined rod, correcting the placement position of the circular part, and preventing the circular part from deviating from the drilling position and affecting the accuracy of simultaneous drilling. At the same time, the adjustment groove disc moves downward with the mounting plate to drive the drill rod to pass through between the two elastic retaining bars, so that the elastic retaining bars move away from each other and bend downward under the pressure of the drill rod. When the drill rod finishes drilling the part below the pressing disc, the drill rod moves upward with the mounting plate. At this time, the elastic retaining bars bend upward under the friction force on the outer side of the drill rod, and the elastic retaining bars are used to clean the drilling debris attached to the surface of the drill rod, avoiding the debris remaining on the surface of the drill rod from affecting the processing accuracy when processing the next group of parts.

[0012] According to the above technical solution, the ventilation and lubrication mechanism includes an air cylinder, which is fixedly connected to the top end of the short fixed shaft. A lower plug piece is slidably connected to the bottom end inside the air cylinder. An upper plug piece is arranged above the lower plug piece. Six liquid supply pipes are fixedly connected to the outer side of the top end of the air cylinder. An air connection pipe is rotatably connected to the center of the top surface of each drilling sprocket. A plurality of ventilation holes are arranged on the side of the pressing strip. Six telescopic pipes are fixedly connected to the bottom surface of the adjustment groove disc. The bottom end of each telescopic pipe is fixedly connected to a thin connection pipe. A limiting block is fixedly connected to the top surface inside the air cylinder. An oil pipe is fixedly connected to the rear side of the air cylinder. The end of the oil pipe away from the air cylinder is fixedly connected to an oil tank.

[0013] According to the above technical solution, a compression spring is arranged between the upper plug piece and the lower plug piece, and the two ends of the compression spring are fixedly connected to the upper plug piece and the lower plug piece respectively, the cross rod is fixedly connected to the lower plug piece, each of the liquid supply pipes is fixedly connected to each telescopic pipe, the end of the air connecting pipe away from the drilling sprocket is fixedly connected to the air cylinder, the vent hole is provided on the bottom surface of the pressure plate, the thin connecting pipe is fixedly connected to the pressure plate, and the ends of the oil pipe and the liquid supply pipe close to one end of the air cylinder are fixedly connected with a one-way valve, and when the pressure plate approaches the adjusting groove plate, the thin connecting pipe begins to shrink toward the inside of the telescopic pipe, At the same time, the cross rod slides along the short solid shaft and pushes the connected lower plug piece, so that the lower plug piece pushes the liquid above and pushes the upper plug piece connected to the pressure spring to slide along the inner wall of the gas cylinder. When the upper plug piece contacts the limit block, the liquid between the upper plug piece and the lower plug piece is located on the side of the liquid supply pipe. As the cross rod continues to move upward, the cross rod drives the lower plug piece to approach the upper plug piece and squeezes the pressure spring, and makes part of the liquid in the upper plug piece and the lower plug piece bracket flow into the liquid supply pipe. When the liquid inside the liquid supply pipe accumulates to a certain amount, the liquid in the liquid supply pipe will flow into the connected drilling sprocket and pass through the drilling sprocket. The connecting hole on the side of the wheel slowly flows out to lubricate the chain, ensuring the smoothness between the chain and the drilled sprocket, reducing the wear of the contact between the chain and the drilled sprocket, and improving the service life of the above structure. At the same time, when the mounting plate and the processed end shell move upward, the cross rod moves downward under the action of gravity, and the cross rod pulls the lower plug to move. At this time, the lower plug pulls the pressure spring and increases the distance between the upper plug and the lower plug. The negative pressure between the lower plug and the upper plug will increase, allowing the liquid in the oil tank to be supplemented between the lower plug and the upper plug through the one-way valve connected to the oil pipe. As the lower plug continues The moving and pulling pressure spring drives the connected upper plug piece to move downward together. At this time, the outside air enters the telescopic tube and the thin connecting tube through the vent hole on the bottom of the pressure plate, and enters the air connecting tube through the top of the telescopic tube, and then enters the upper part of the upper plug piece through the air connecting tube, so that the air inside the air cylinder on the upper plug piece is filled. When the cross rod pushes the lower plug piece upward again, the lower plug piece pushes the upper plug piece according to the above process to discharge the air filled in the air cylinder through the bottom of the vent hole on the bottom of the pressure plate, so that the air sprayed from the vent hole can blow away the attachments on the top of the parts to avoid affecting the processing of the parts.

At the same time, the air ejected through the ventilation hole blows off the attachments above the part, avoiding affecting part processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The interior of the pressure plate 63 is a hollow structure, and the pressure strip 69 is located at the bottom edge of the reserved groove 62 to correct the placement of the circular parts to prevent the circular parts from deviating from the drilling position and affecting the accuracy of simultaneous drilling. At the same time, the adjustment groove plate 510 moves downward with the mounting plate 10 to drive the drill rod 9 to pass through the two elastic baffles 64, so that the elastic baffles 64 are pressed by the drill rod 9 and move away from each other and bend downward. When the drill rod 9 finishes drilling the parts below the pressure plate 63, the drill rod 9 moves upward with the mounting plate 10. At this time, the elastic baffle 64 is bent upward by the friction force on the outside of the drill rod 9, and the elastic baffle 64 is used to clean the drilling debris attached to the surface of the drill rod 9 to avoid the debris remaining on the surface of the drill rod 9 affecting the processing accuracy when processing the next group of parts.

[0036] The ventilation and lubrication mechanism 7 includes an air cylinder 71, which is fixedly connected to the top of the short fixed shaft 512. The inner bottom end of the air cylinder 71 is slidably connected to a lower plug plate 73, and an upper plug plate 72 is arranged above the lower plug plate 73. Six liquid supply pipes 74 are fixedly connected to the outer side of the top of the air cylinder 71, and an air connecting pipe 75 is rotatably connected to the top axis of each drilled sprocket 57. A plurality of ventilation holes 76 are arranged on the side of the pressure strip 69.

The end of the oil pipe 79 away from the air cylinder 71 is fixedly connected to an oil tank 710.

[0037] A compression spring is provided between the upper plug piece 72 and the lower plug piece 73, and the two ends of the compression spring are fixedly connected to the upper plug piece 72 and the lower plug piece 73 respectively, the cross rod 61 is fixedly connected to the lower plug piece 73, each liquid supply pipe 74 is fixedly connected to each telescopic pipe 77, the end of the air connecting pipe 75 away from the drilling sprocket 57 is fixedly connected to the air cylinder 71, the vent hole 76 is provided on the bottom surface of the pressure plate 63, the thin connecting pipe 78 is fixedly connected to the pressure plate 63, the oil pipe 79 and the end of the liquid supply pipe 74 close to the air cylinder 71 are fixedly connected with a one-way valve, and the oil slowly flows out through the connecting hole on the side of the drilling sprocket 57 to lubricate the chain 56, so as to ensure that the chain 56 is in contact with the drilling chain The smoothness between the wheels 57 is reduced, the wear of the contact between the guarantee chain 56 and the drilling sprocket 57 is reduced, and the service life of the above structure is improved. At the same time, the top of the telescopic tube 77 enters the air connecting tube 75, and then enters the upper part of the upper plug piece 72 through the air connecting tube 75, so that the air inside the air cylinder 71 on the upper plug piece 72 is filled. When the cross rod 61 pushes the lower plug piece 73 to move upward again, the lower plug piece 73 pushes the upper plug piece 72 according to the above process to discharge the air filled in the air cylinder 71 through the bottom of the vent hole 76 on the bottom surface of the pressure plate 63, so that the air sprayed from the vent hole 76 will blow away the attachments above the parts to avoid affecting the part processing.

[0038] Working principle: When the hydraulic rod connected to the mounting plate 10 extends downward, the mounting plate 10 moves downward to push the support frame 1 to move downward together. By rotating the external motor on the shaft seat 3, the connected adjusting worm 8 rotates, causing the adjusting worm 8 to drive the engaged turbine shaft cylinder 515. The rotation of the turbine shaft cylinder 515 drives the connected deflecting sheave 511 to rotate, so that the deflecting sheave 511 pushes the pressure-receiving cylinder 58 to be pressurized through the inclined push groove 514. Thus, after the pressure-receiving cylinder 58 is pressurized, it drives the connected smooth groove block 59 to slide along the slide block groove 513, and the movement of the slide block groove 513 adjusts the position of the drill rod 9 connected to the pressure-receiving cylinder 58. When the smooth groove block 59 approaches the center of the adjusting groove disc 510 along the slide block groove 513, the return spring in the inner sliding cylinder 55 releases elastic force to push the socket cylinder 54 away from the processing end shell 2, and makes the rotating shaft slider 52 connected to the socket cylinder 54 slide along the slide block plate 51. During this process, the external motor on the rotating shaft slider 52 rotates to drive the transmission sprocket 53 to rotate, so that the chain 56 connected to the outside of the transmission sprocket 53 drives other engaged drilling sprockets 57 to rotate. The rotation of the drilling sprocket 57 drives the connected drill rod 9 to rotate. The drill rod 9 moves downward together with the processing end shell 2 connected to the support frame 1 to perform simultaneous drilling on multiple positions of the part. At the same time, by using the rotation of the deflecting sheave 511 to adjust the position of the smooth groove block 59 on the adjusting groove disc 510, while improving the drilling efficiency of the part, by adjusting the drilling position of the drill rod 9, it is possible to drill different-sized parts or different positions, improving the adaptability range and flexibility of part processing;

[0039] When the mounting plate 10 moves downward, the short fixing shaft 512 pushes the pressure-applying disc 63 to contact the top surface of the part through the connected cross bar 61. As the mounting plate 10 continues to move downward, the cross bar 61 slides upward along the short fixing shaft 512. At this time, the correction inclined rod 67 connected to the pressure-applying disc 63 contacts the edge of the circular part, and squeezes the edge of the circular part through the inclined surface of the correction inclined rod 67, so that the edges of the six places of the circular part are all pressurized by the correction inclined rod 67. At this time, after being pressurized by the correction inclined rod 67, it drives the connected chute rod 66 to slide along the pressure-applying disc 63 and pull the spring piece 65, thus preventing the edge of the circular part from being deformed due to excessive pressure, and making the pressurized circular part move to the center of the pressure-applying disc 63 after being pressurized by the correction inclined rod 67 to correct the placement position of the circular part, preventing the circular part from deviating from the drilling position and affecting the accuracy of simultaneous drilling. At the same time, the adjusting groove disc 510 moves downward with the mounting plate 10 to drive the drill rod 9 to pass through between the two elastic retaining strips 64, so that the elastic retaining strips 64 move away from each other and bend downward under the pressure of the drill rod 9. When the drilling of the part below the pressure-applying disc 63 by the drill rod 9 is completed, the drill rod 9 moves upward with the mounting plate 10. At this time, the elastic retaining strips 64 bend upward under the frictional force on the outside of the drill rod 9, and use the elastic retaining strips 64 to clean the drilling debris attached to the surface of the drill rod 9, avoiding the debris remaining on the surface of the drill rod 9 from affecting the processing accuracy when processing the next group of parts;

[0040] When the pressure - applying disc 63 approaches the adjusting groove disc 510, the thin connecting pipe 78 starts to contract into the telescopic pipe 77. At the same time, the cross - bar 61 slides along the short fixed shaft 512 and pushes the connected lower plug piece 73, so that the lower plug piece 73 pushes the liquid above it and the upper plug piece 72 connected after pushing the pressure - applying spring slides along the inner wall of the air cylinder 71. When the upper plug piece 72 contacts the limit block 711, at this time, the liquid between the upper plug piece 72 and the lower plug piece 73 is located on the side of the liquid supply pipe 74. As the cross - bar 61 continues to move upward, the cross - bar 61 drives the lower plug piece 73 to approach the upper plug piece 72 and compresses the pressure - applying spring, and part of the liquid inside the upper plug piece 72 and the lower plug piece 73 flows into the liquid supply pipe 74. When the liquid inside the liquid supply pipe 74 accumulates to a certain amount, the liquid in the liquid supply pipe 74 will flow into the connected drilling sprocket 57 and slowly flow out through the communication holes on the side of the drilling sprocket 57 to lubricate the chain 56, ensuring the smoothness between the chain 56 and the drilling sprocket 57, reducing the wear of the contact between the chain 56 and the drilling sprocket 57, and improving the service life of the above - mentioned structure. At the same time, when the mounting plate 10 and the processing end - shell 2 move upward, the cross - bar 61 moves downward under the action of gravity. The cross - bar 61 pulls the lower plug piece 73 to move. At this time, the lower plug piece 73 pulls the pressure - applying spring and increases the distance between the upper plug piece 72 and the lower plug piece 73. The negative pressure between the lower plug piece 73 and the upper plug piece 72 will increase, allowing the liquid in the fuel tank 710 to be supplemented between the lower plug piece 73 and the upper plug piece 72 through the one - way valve connected by the oil pipe 79. As the lower plug piece 73 continues to move and pulls the pressure - applying spring to drive the connected upper plug piece 72 to move downward together, at this time, the outside air enters the telescopic pipe 77 and the thin connecting pipe 78 through the ventilation hole 76 on the bottom surface of the pressure - applying disc 63, and enters the air - connecting pipe 75 through the top of the telescopic pipe 77, and then enters above the upper plug piece 72 through the air - connecting pipe 75, filling the air inside the air cylinder 71 on the upper plug piece 72. When the cross - bar 61 pushes the lower plug piece 73 to move upward again, the lower plug piece 73 pushes the upper plug piece 72 according to the above process to discharge the air filled inside the air cylinder 71 through the bottom of the ventilation hole 76 on the bottom surface of the pressure - applying disc 63, so as to blow off the attachments above the parts with the air ejected from the ventilation hole 76, avoiding affecting the part processing.
