Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a drilling device for processing automobile parts using new materials. Background Art

[0002] During the assembly process of automobile production, a large number of automobile parts are usually required for assembly. During the production process of automobile parts, drilling processing is usually required to make them meet the requirements of assembly production operations.

[0003] Since new materials are now widely used, some auto parts are made of new materials for production cost and safety performance considerations. In addition, auto parts are relatively complex, so the materials of each part are different. When drilling materials of different strengths, using the same drilling speed can easily cause damage to parts of materials with lower strength, and the drilling efficiency of materials with higher strength is lower. Therefore, some drilling equipment now uses variable speed to perform drilling operations on different materials.

[0004] During drilling operations, the borehole and drill rod positions are usually cooled by spraying. However, the common spray cooling method now is usually constant spraying, which cannot be effectively adapted to parts of different strengths and different rotation speeds. Therefore, when spraying on materials with lower strength, the spray intensity is too high, resulting in the cooling liquid being unable to stably and continuously enter the borehole, resulting in reduced lubrication effect on the drill rod, and further causing damage to the parts or drill rod. When spraying on materials with higher strength, the spray intensity is insufficient, resulting in the inability to quickly and effectively remove heat, leading to local overheating and the like. Therefore, the present invention provides a drilling device for processing automotive parts using new materials to solve the above-mentioned problems. Summary of the Invention

[0010] As a further solution of the present invention, the adjusting member further includes a reset spring. The reset spring is fixedly installed on the side wall of the auxiliary plate away from the moving tooth plate, and one end of the reset spring away from the auxiliary plate is fixedly installed on the corresponding wall surface in the reset groove.

[0011] As a further solution of the present invention, the adjusting member further includes an auxiliary adjusting groove. The auxiliary adjusting groove is opened on the bottom of the extension plate corresponding to the side wall of the moving groove. One end of the moving tooth plate away from the centrifugal component is connected to the waste strip blocking component at the bottom.

[0012] As a further solution of the present invention, the centrifugal component includes a counterweight and a connecting belt.

[0015] As a further solution of the present invention, the spraying component further includes an intensity adjusting member capable of adjusting the spraying intensity of the spray head according to the adjusting angle of the spray head.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the present invention is in use, with the change of the drill bit rotation speed, the centrifugal force generated by the rotation drives the counterweight block to adjust adaptively. Then, through the pulling rope, the moving tooth plate, the adjusting gear and the movable shaft, the spray head is driven to adjust the adaptively angle. During this process, the intensity adjusting member will receive the angle change of the spray head and converge and separate the converging plate through the converging belt, thereby effectively changing the intensity of the cooling liquid sprayed out. As a result, when operating at a slow rotation speed, the spray head can continuously spray at a low intensity above the drill bit, so that the cooling liquid will be transmitted along the thread groove on the drill bit into the drill hole, thus effectively lubricating and cooling the drill hole position. When operating at a high rotation speed, the spray head will spray at a high intensity below the drill bit, and the high-speed fluid impact can quickly take away the heat, preventing local overheating from causing the drill bit to anneal or the material surface to harden. Therefore, it can effectively adjust adaptively under the operation requirements of different rotation speeds and different materials, avoiding damage to parts caused by inappropriate spray cooling; 2. When the present invention is in use, the waste strip blocking component can effectively block the waste strips generated by drilling parts with adaptable strength according to different rotation speeds. When drilling a material with a lower strength, due to its lower strength, the waste strip will bend or break after rising to a certain extent. At this time, the waste strip blocking component can effectively prevent the waste strip from accumulating on the drill bit. When quickly operating on a material with a higher strength, at this time, the waste strip blocking component will descend on the drill bit, so that the extension length of the waste strip is limited, and the extension of the waste strip can be blocked in advance, avoiding the situation that the high-strength material accumulates on the drill bit and is not easy to clean. Therefore, it can block and process the waste material adaptively. Description of the Drawings

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 7, in the embodiments of the present invention, a drilling device for processing automotive parts using new materials includes a device base 1. A lifting frame 2 is fixedly installed on the top of the device base 1. A device box 3 is movably installed on the top of the lifting frame 2. Inside the device box 3, a driving motor, a lifting cylinder, and a cooling liquid tank are installed. The driving motor is a publicly known technology and will not be elaborated here. Specifically, the driving motor is a motor capable of changing the rotational speed. The position of the lifting cylinder corresponds to the position of the lifting frame 2. Through the lifting cylinder, the device box 3 can be adjusted up and down on the lifting frame 2. A control valve for controlling the discharge of the cooling liquid is provided inside the cooling liquid tank. A control box 4 is fixedly installed on one side of the device box 3. A control device is installed inside the control box 4. The control end of the control device is connected to the input ends of the driving motor and the lifting cylinder. The control end of the control device is also connected to the control valve inside the cooling liquid tank. Through the control device, the driving motor and the lifting cylinder can be controlled to operate, and the control device can also control the opening or closing of the control valve inside the cooling liquid tank. A placement platform 5 is fixedly installed on the lifting frame 2. Clamping fixing plates 6 are movably installed on both sides of the placement platform 5. The clamping fixing plates 6 can be telescopically adjusted on the placement platform 5 to clamp the parts on the placement platform 5. A rotating shaft assembly is movably installed at the bottom of the device box 3. The top end of the rotating shaft assembly is connected to the output end of the driving motor, and the top end of the rotating shaft assembly also corresponds to the position of the control valve inside the cooling liquid tank. The cooling liquid inside the cooling liquid tank can be transmitted through the rotating shaft assembly. A drill bit 7 is clamped and installed at the bottom of the rotating shaft assembly. By starting the driving motor, the rotating shaft assembly drives the drill bit 7 to perform drilling operations on the parts.

[0027] The rotating shaft assembly includes a main shaft 8 and an attachment block 9. The attachment block 9 is fixedly installed on the bottom wall surface of the main shaft 8. The drill bit 7 is clamped and installed at the bottom of the attachment block 9.

[0028] Centrifugal components and spraying components are installed on both sides of the side wall of the attachment block 9. A waste strip blocking component is installed at the bottom of the attachment block 9. The centrifugal components are arranged above the spraying components, and the side of the centrifugal components away from the attachment block 9 is connected to the spraying components. The waste strip blocking component is arranged below the spraying components, and the waste strip blocking component is connected to the spraying components.

[0029] The spray assembly includes an extension plate 10, a spray control groove 11, a spray head 12, a transmission pipe 13, a movable shaft 22 and an adjusting member. The extension plate 10 is fixedly installed at the bottom sides of the attachment block 9. The spray control groove 11 is opened on the top wall surface of the extension plate 10 and penetrates through the bottom wall surface of the extension plate 10. The spray head 12 is arranged inside the spray control groove 11, and movable shafts 22 are fixedly installed at both ends of the spray head 12. The ends of the movable shafts 22 away from the spray head 12 are movably installed on the corresponding position wall surfaces inside the spray control groove 11. The top end of the transmission pipe 13 is fixedly installed on the corresponding position wall surface of the top of the spray head 12. The end of the transmission pipe 13 away from the spray head 12 penetrates through the corresponding position wall surface of the main shaft 8. Through the main shaft 8, the position of the end of the transmission pipe 13 away from the spray head 12 is communicated with the position of the control valve in the corresponding cooling liquid tank on the rotating shaft assembly. The adjusting member is installed on both sides inside the extension plate 10. The adjusting member and the movable shaft 22 are movably connected to each other, and one end of the adjusting member is connected to the centrifugal assembly, and the other end of the adjusting member is connected to the waste strip blocking assembly. By changing the rotational speed of the drive motor, the centrifugal assembly is adjusted adaptively according to the centrifugal intensity, so as to drive the adjusting member to perform adjustment operations. Through the adjustment of the adjusting member, the movable shaft 22 connected to the adjusting member can drive the spray head 12 to perform adaptive rotational adjustment. When the drill bit 7 rotates slowly, the bottom end of the spray head 12 will face the upper position of the side wall of the drill bit 7. When the drill bit 7 rotates quickly, the bottom end of the spray head 12 will face the lower position of the side wall of the drill bit 7. At the same time, since the adjusting member is connected to the waste strip blocking assembly, when the adjusting member makes adjustments, it can also drive the waste strip blocking assembly to perform a downward adjustment on the drill bit 7. When the drill bit 7 rotates slowly, the waste strip blocking assembly is located at the upper position of the side wall of the drill bit 7. When the drill bit 7 rotates quickly, the waste strip blocking assembly will perform a downward adjustment on the drill bit 7. When the drill bit 7 performs drilling operations on materials of different strengths, different rotational speeds will be used. Therefore, when performing slow operations on materials with lower strength, the waste strips from drilling will move upward along the spiral groove of the drill bit 7. Since the material strength is low, the waste strips will bend or break after rising to a certain extent. At this time, the waste strip blocking assembly can effectively prevent the waste strips from accumulating on the drill bit 7, and due to the slow rotation, it will not cause the broken waste strips to fly everywhere. When performing fast operations on materials with higher strength, at this time, the waste strip blocking assembly will perform a downward movement on the drill bit 7, so that the extension length of the waste strips is limited, and the extension of the waste strips can be blocked in advance, avoiding the situation that the high-strength materials accumulate on the drill bit 7 and are difficult to clean up.

[0030] The adjusting member includes a reset groove 14, a moving groove 20, a moving tooth plate 21, an adjusting gear 23, an auxiliary plate 24, a reset spring 25, a pulling rope 26, and an auxiliary adjusting groove 27. The reset groove 14 is opened at the positions of the two side walls of the extension plate 10 away from one end of the attachment block 9. The moving groove 20 is opened on the two inner side walls of the extension plate 10, and one end of the moving groove 20 away from the attachment block 9 communicates with the reset groove 14. The moving tooth plate 21 is installed at the inner bottom of the moving groove 20, and the moving tooth plate 21 can move horizontally in the moving groove 20. The adjusting gear 23 is fixedly installed on the movable shaft 22, and the adjusting gear 23 is located inside the moving groove 20. The adjusting gear 23 meshes with the moving tooth plate 21. The auxiliary plate 24 is fixedly installed at one end of the moving tooth plate 21 close to the reset groove 14, and the auxiliary plate 24 is located in the reset groove 14. The pulling rope 26 is fixedly installed at the position of one end of the auxiliary plate 24 away from the moving tooth plate 21. One end of the pulling rope 26 away from the auxiliary plate 24 slides through the corresponding wall surface of the extension plate 10 and is connected to the centrifugal component. The reset spring 25 is fixedly installed on the side wall of the auxiliary plate 24 away from the moving tooth plate 21, and one end of the reset spring 25 away from the auxiliary plate 24 is fixedly installed on the corresponding wall surface in the reset groove 14. The pulling rope 26 is located inside the reset spring 25. Through the reset spring 25, the auxiliary plate 24 can be driven to perform a reset adjustment towards the inner side of the moving groove 20. The auxiliary adjusting groove 27 is opened on the bottom of the extension plate 10 corresponding to the side wall of the moving groove 20. The bottom of the end of the moving tooth plate 21 away from the centrifugal component is connected to the waste strip blocking component.

[0031] The centrifugal component includes a counterweight 15 and a connecting belt 16. The connecting belt 16 is fixedly installed at the top end position of the side wall of the attachment block 9. The counterweight 15 is fixedly installed at the position of one end of the connecting belt 16 away from the attachment block 9. The bottom wall surface of the counterweight 15 is connected to the adjusting member on the spraying component. Specifically, one end of the pulling rope 26 away from the auxiliary plate 24 is fixedly installed on the bottom wall surface of the counterweight 15. By the rotation of the drill bit 7, the counterweight 15 can be lifted under the influence of centrifugal force. As the rotation speed of the drill bit 7 changes, the centrifugal force received by the counterweight 15 increases, so that the lifting amplitude of the counterweight 15 increases, and then the adjusting member can be driven to perform an adaptive adjustment according to the rotation speed change.

[0032] The waste strip blocking component includes a movable sleeve 17, a blocking blade 18, side plates 19, and an adjusting frame. The movable sleeve 17 is located at the bottom of the attachment block 9. The inner diameter of the movable sleeve 17 is adapted to the outer diameter of the drill bit 7. The blocking blade 18 is fixedly installed at the bottom of the movable sleeve 17. The side plates 19 are fixedly installed on the front and rear side walls of the movable sleeve 17. The adjusting frame is installed on the left and right sides of the side plates 19. One end of the adjusting frame away from the side plates 19 is installed on the adjusting member on the spraying component. Specifically, one end of the adjusting frame away from the side plates 19 is movably installed at the bottom of the end of the moving tooth plate 21 away from the centrifugal component.

[0033] The adjusting frame includes a lifting rod 28, a pushing rod 29, and an adjusting rod 30. The bottom end of the lifting rod 28 is movably installed on the side wall of the side plate 19. The pushing rod 29 is obliquely arranged on the side away from the side plate 19 of the lifting rod 28. The top end of the pushing rod 29 and the top end of the lifting rod 28 are movably connected to each other. The adjusting rod 30 is obliquely arranged at a position away from the lifting rod 28 on the pushing rod 29. The bottom end of the adjusting rod 30 and the bottom end of the pushing rod 29 are movably connected to each other. The top end of the adjusting rod 30 is movably installed on the adjusting member. Specifically, the top end of the adjusting rod 30 is movably installed on the bottom wall surface of the moving tooth plate 21. The adjusting rod 30 can move inside the auxiliary adjusting groove 27. Further, the bottom end of the lifting rod 28 can be rotationally adjusted on the side plate 19. The top end of the pushing rod 29 can be rotationally adjusted on the top end of the lifting rod 28. The bottom end of the adjusting rod 30 can be rotationally adjusted on the bottom end of the pushing rod 29. The top end of the adjusting rod 30 can be rotationally adjusted on the bottom wall surface of the moving tooth plate 21. When the moving tooth plate 21 moves away from the attachment block 9 inside the moving groove 20, the top end of the adjusting rod 30 will move synchronously with the moving tooth plate 21. Limited by the fixed length, the bottom end of the adjusting rod 30 will be adaptively lifted upward. At the same time, the bottom end of the adjusting rod 30 will also drive the bottom end of the pushing rod 29 to move away from the lifting rod 28. Similarly limited by the fixed length, the top end of the pushing rod 29 will drive the top end of the lifting rod 28 to descend, so that the movable sleeve 17 descends. On the contrary, when the moving tooth plate 21 moves closer to the attachment block 9, under the adjustment of the adjusting rod 30 and the pushing rod 29, the lifting rod 28 will drive the movable sleeve 17 to be squeezed and lifted upward.

[0034] The rotating shaft assembly further includes a movable card slot 36, a liquid inlet conduit 37, a driving shaft 38, and a cooling liquid box 39. The movable card slot 36 is opened at the top end position of the side wall of the main shaft 8. Through the movable card slot 36, the top end of the main shaft 8 is movably installed on the bottom wall surface of the equipment box 3. The cooling liquid box 39 is fixedly installed on the inner bottom wall surface of the equipment box 3, and the inner diameter size of the cooling liquid box 39 is adapted to the outer diameter size of the main shaft 8. The inside of the cooling liquid box 39 is communicated with the output end of the control valve in the cooling liquid tank. The liquid inlet conduit 37 is fixedly installed on the top of the main shaft 8. The inside of the liquid inlet conduit 37 is communicated with the inside of the main shaft 8 and the transfer pipe 13. The top end of the liquid inlet conduit 37 is communicated with the inside of the cooling liquid box 39. The driving shaft 38 is fixedly installed on the top wall surface of the main shaft 8. One end of the driving shaft 38 away from the main shaft 8 is connected to the output end of the driving motor.

[0035] The main shaft 8 is driven to rotate by the driving shaft 38, so that the liquid inlet conduit 37 and the spray assembly on the attachment block 9 rotate synchronously. At the same time, the cooling liquid can be transmitted to the liquid inlet conduit 37 through the cooling liquid box 39, and is transmitted to the spray head 12 through the liquid inlet conduit 37 and the transmission pipe 13 to perform a cooling spraying operation, thereby effectively avoiding the occurrence of entanglement of the transmission pipe 13 and obstruction of the cooling liquid supply due to rotation during the rotation operation, and can effectively and smoothly transmit the cooling liquid.

[0036] The spray assembly also includes a spray intensity of the spray head 12 that can be adjusted according to the adjustment angle of the spray head 12. The intensity adjustment member is installed in the spray control groove 11, and the intensity adjustment member is also connected to the spray head 12. When the angle of the spray head 12 is adjusted, the intensity of the cooling liquid discharged by the spray head 12 can be adaptively adjusted through the intensity adjustment member. When the slow drilling operation is performed, the bottom end of the spray head 12 will be toward the upper position of the drill bit 7. At this time, the intensity adjustment member adjusts the intensity to be lower, so that the pressure intensity of the spray from the spray head 12 is lower, so that the cooling liquid sprayed can be more gently rinsed on the position above the drill bit 7. When the drill bit 7 is slow, the bottom end of the spray head 12 will be toward the upper position of the drill bit 7. During rotation, the cooling liquid can be effectively and continuously transmitted along the spiral groove of the drill bit 7 to the drilling position of the part, so that the drill hole can be continuously flushed, thereby effectively lubricating and cooling the drilling position, reducing the damage to parts made of low-strength materials. When performing rapid drilling operations, the bottom end of the spray head 12 will be toward the lower position of the drill bit 7. At this time, the strength adjustment part adjusts the intensity to increase the pressure intensity of the spray of the spray head 12, thereby increasing the flow rate of the cooling liquid, which can quickly flush the drilling position. The high-speed fluid impact can quickly take away heat to prevent local overheating from causing annealing of the drill bit 7 or hardening of the material surface.

[0037] The intensity adjusting member includes a drawstring 31, a rubber diversion ring 32, a split plate 33, a draw-in groove 34 and a draw-in ring 35. The split plate 33 is in the shape of an arc plate. The split plate 33 is annularly and movably installed inside the spray head 12. Multiple split plates 33 inside the spray head 12 can be adjusted to open and close. When multiple split plates 33 are closed, the multiple split plates 33 form a funnel shape. The rubber diversion ring 32 is an elastic adjusting tube. The rubber diversion ring 32 is arranged inside the split plate 33. The top end of the rubber diversion ring 32 is fixedly installed on the corresponding position wall surface inside the spray head 12. The draw-in groove 34 is opened on the outer side wall of the split plate 33. One end of the drawstring 31 is fixedly installed on the corresponding position wall surface inside the spray control groove 11, and the other end penetrates through the corresponding position wall surface of the spray head 12 and is arranged around the draw-in groove 34 on the outer side wall of the drawstring 31. The draw-in ring 35 is movably sleeved on the drawstring 31, and one end of the drawstring 31 far from the inner side wall of the spray control groove 11 is fixedly installed on the corresponding position wall surface of the draw-in ring 35. When the bottom end of the spray head 12 is adjusted from a position above the side wall of the drill bit 7 to a position below the side wall of the drill bit 7, the drawstring 31 will perform a draw-in adjustment on the multiple split plates 33 inside the spray head 12, so that the multiple split plates 33 are gradually closed, thereby increasing the pressure of the cooling liquid transmitted through the spray head 12. When the bottom end of the spray head 12 is adjusted from a position below the side wall of the drill bit 7 to a position above the side wall of the drill bit 7, the drawstring 31 no longer performs a draw-in adjustment. At the same time, under the transmission pressure of the cooling liquid inside the spray head 12, the multiple split plates 33 are separated and opened, thereby reducing the pressure of the cooling liquid transmitted through the spray head 12.

[0038] The working principle of the present invention is: When the present invention is in use, the parts to be processed are placed on the placement platform 5, and the parts on the placement platform 5 are clamped and fixed by adjusting the clamping fixing plate 6. The driving motor and the lifting cylinder inside the equipment box 3 are controlled by the control box 4 to perform operations, so that the drill bit 7 drills the parts. Due to the rotation of the drill bit 7, the counterweight blocks 15 on both sides of the attachment block 9 are lifted upward under the influence of centrifugal force, and the lifting angle thereof changes adaptively according to the rotation speed of the drill bit 7. When the counterweight blocks 15 are lifted, the counterweight blocks 15 will pull the auxiliary plate 24 to move through the pulling rope 26, so that the moving tooth plate 21 drives the adjusting gear 23 to perform adaptive adjustment, and the spray head 12 performs adaptive rotation adjustment through the movable shaft 22, thereby completing the adaptive condition of the spray angle of the spray head 12. Under the adaptive convergence adjustment of the intensity adjustment member, the spray intensity of the spray head 12 is correspondingly adjusted, so that the drill bit 7 can be effectively cooled during drilling. At the same time, when the moving tooth plate 21 is adjusted, the waste strip blocking assembly will perform adaptive downward adjustment through the adjusting frame, so that the waste strip blocking can be effectively adjusted adaptively according to the part material, and thus the cooling and waste strip blocking can be effectively adjusted adaptively for parts of different materials.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
