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

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

In this process, the intensity adjusting part is affected by the angle change of the spray head and tightens the separation plate through the tightening belt, thereby effectively changing the intensity of the cooling liquid sprayed, so that when the speed is slow, the spray head can effectively spray the position above the drill bit with low intensity continuously, so that the cooling liquid is transmitted into the drill hole along the thread groove on the drill bit, thereby effectively lubricating and cooling the drill position. When the speed is high, the spray head can spray the position below the drill bit with high intensity. The high-speed fluid impact can quickly take away the heat, preventing local overheating from causing annealing of the drill bit or hardening of the material surface, so that it can effectively perform adaptive adjustment under the working requirements of different speeds and different materials, and avoid the damage of parts caused by incompatible spray cooling.

[0019] 2. When the present invention is used, the waste strip blocking assembly can effectively block the waste strips generated by drilling parts of adaptive strength according to different rotation speeds. When drilling materials with lower strength, the waste strips will bend or break after rising to a certain level due to their lower strength. At this time, the waste strip blocking assembly can effectively prevent the waste strips from accumulating on the drill bit. When high-strength materials are operated quickly, the waste strip blocking assembly will descend on the drill bit, thereby limiting the extension length of the waste strips and blocking the extension of the waste strips in advance, avoiding the accumulation of high-strength materials on the drill bit, which makes it difficult to clean up, thereby enabling adaptive blocking of waste materials.

A placement platform 5 is fixedly installed on the lifting frame 2, and 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 equipment box 3. The top of the rotating shaft assembly is connected to the output end of the driving motor, and the top of the rotating shaft assembly also corresponds to the position of the control valve in the cooling liquid tank. The cooling liquid in the cooling liquid tank can be transmitted through the rotating shaft assembly. A drill bit 7 is clamped and installed on the bottom of the rotating shaft assembly. When the driving motor is started, the rotating shaft assembly drives the drill bit 7 to drill the parts.

[0030] The rotating shaft assembly includes a main shaft 8 and an attachment block 9 . The attachment block 9 is fixedly mounted on the bottom wall of the main shaft 8 , and the drill bit 7 is clamped and mounted on the bottom of the attachment block 9 .

[0031] Centrifugal components and spray components are installed on both sides of the side wall of the attachment block 9, and a waste strip blocking component is installed at the bottom of the attachment block 9. The centrifugal component is arranged above the spray component, and the centrifugal component is connected to the spray component on the side away from the attachment block 9. The waste strip blocking component is arranged below the spray component, and the waste strip blocking component and the spray component are connected to each other.

[0032] 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 mounted on the bottom of both sides of the attachment block 9. The spray control groove 11 is opened on the top wall of the extension plate 10, and the spray control groove 11 passes through the bottom wall of the extension plate 10. The spray head 12 is arranged inside the spray control groove 11, and both ends of the spray head 12 are fixedly mounted with a movable shaft 22. The end of the movable shaft 22 is movably mounted on the wall at the corresponding position inside the spray control groove 11 away from the spray head 12. The top of the transmission pipe 13 is fixedly mounted on the wall at the corresponding position on the top of the spray head 12. The transmission pipe 13 is away from the top of the spray head 12. One end of the spray head 12 passes through the wall surface at the corresponding position of the main shaft 8, and the transmission pipe 13 is connected to the position of the control valve in the cooling liquid tank corresponding to the cooling liquid tank on the rotating shaft assembly through the main shaft 8. The adjusting member is installed on both sides of the interior of 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 speed of the driving motor, the centrifugal assembly is adaptively adjusted by the centrifugal strength, thereby driving the adjusting member to perform the adjustment operation. By adjusting the adjusting member, the movable shaft 22 connected to the adjusting member can drive the spray head 12 to Adaptive rotation adjustment, when the drill bit 7 rotates slowly, the bottom end of the spray head 12 will be toward the upper position of the side wall of the drill bit 7, and when the drill bit 7 rotates quickly, the bottom end of the spray head 12 will be toward the lower position of the side wall of the drill bit 7. At the same time, the adjustment part is connected to the waste strip barrier assembly, so that the adjustment part can also drive the waste strip barrier assembly to be lowered on the drill bit 7 when adjusting. When the drill bit 7 rotates slowly, the waste strip barrier assembly is located above the side wall of the drill bit 7. When the drill bit 7 rotates quickly, the waste strip barrier assembly will be lowered on the drill bit 7. When the drill bit 7 is drilling materials of different strengths, different rotation speeds will be used. Therefore, when slow operation is adopted for materials with lower strength, the waste strips being drilled will move upward along the spiral groove of the drill bit 7. Due to the low strength of the material, the waste strips will bend or break after rising to a certain extent. At this time, the waste strip blocking component can effectively prevent the waste strips from accumulating on the drill bit 7, and due to the slow rotation, the broken waste strips will not be splashed everywhere. When fast operation is adopted for materials with higher strength, the waste strip blocking component will descend on the drill bit 7, thereby limiting the extension length of the waste strips, and being able to block the extension of the waste strips in advance, thereby avoiding the accumulation of high-strength materials on the drill bit 7, which makes it difficult to clean up.

[0033] 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 bottom wall of the counterweight 15 is connected to the adjusting part on the spray assembly. Specifically, the pulling rope 26 is fixedly installed on the bottom wall of the counterweight 15 away from the auxiliary plate 24. The rotation of the drill bit 7 can make the counterweight 15 lifted by the centrifugal force. As the speed of the drill bit 7 changes, the centrifugal force on the counterweight 15 increases, thereby increasing the lifting amplitude of the counterweight 15, and then driving the adjusting part to make adaptive adjustments according to the change in speed.

[0035] The waste strip blocking assembly includes a movable sleeve 17, a blocking blade 18, a side plate 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 mounted on the bottom of the movable sleeve 17. The side plates 19 are fixedly mounted on the front and rear side walls of the movable sleeve 17.

[0036] 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 mounted on the side wall of the side plate 19.

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 mounted on the adjusting member. Specifically, the top end of the adjusting rod 30 is movably mounted on the bottom wall of the movable tooth plate 21. The adjusting rod 30 can move inside the auxiliary adjustment slot 27. Further, the bottom end of the lifting rod 28 can be rotated and adjusted on the side plate 19, and the top end of the pushing rod 29 can be rotated and adjusted on the top end of the lifting rod 28. The bottom end of the adjusting rod 30 can be rotated and adjusted on the pushing rod When the movable tooth plate 21 moves toward the side close to the attachment block 9, the lifting rod 28 drives the movable sleeve 17 to be squeezed and adjusted under the adjustment of the adjusting rod 30 and the pushing rod 29.

[0037] The rotating shaft assembly also includes a movable slot 36, a liquid inlet conduit 37, a drive shaft 38 and a cooling liquid box 39. The movable slot 36 is opened at the top position of the side wall of the main shaft 8. The top of the main shaft 8 is movably mounted on the bottom wall of the equipment box 3 through the movable slot 36. The cooling liquid box 39 is fixedly mounted on the inner bottom wall of the equipment box 3, and the inner diameter of the cooling liquid box 39 is adapted to the outer diameter of the main shaft 8. The interior of the cooling liquid box 39 and the output end of the control valve in the cooling liquid tank are interconnected. The liquid inlet conduit 37 is fixedly mounted on the top of the main shaft 8. The interior of the liquid inlet conduit 37 is interconnected through the main shaft 8 and the interior of the transmission pipe 13. The top of the liquid inlet conduit 37 and the interior of the cooling liquid box 39 are interconnected. The drive shaft 38 is fixedly mounted on the top wall of the main shaft 8. The end of the drive shaft 38 away from the main shaft 8 is connected to the output end of the drive motor.

[0038] 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.

[0039] 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.

[0040] The strength adjustment part includes a tightening belt 31, a rubber guide ring 32, a separating plate 33, a tightening groove 34 and a tightening ring 35. The separating plate 33 is an arc-shaped plate. The separating plate 33 is movably mounted on the inner side of the sprinkler head 12 in an annular shape. The multiple groups of combining plates 33 in the sprinkler head 12 can be adjusted to open and close. When the multiple groups of combining plates 33 are in a closed state, the multiple groups of combining plates 33 form a funnel shape. The rubber guide ring 32 is an elastic adjustment tube. The rubber guide ring 32 is arranged on the inner side of the separating plate 33. The top of the rubber guide ring 32 is fixedly mounted on the corresponding position wall of the inner side of the sprinkler head 12. The tightening groove 34 is provided on the outer side wall of the separating plate 33. One end of the tightening belt 31 is fixedly mounted on the corresponding position wall of the inner side of the spray control groove 11, and the other end passes through the corresponding position wall of the sprinkler head 12 and along the tightening groove 34 on the outer wall of the tightening belt 31 The circumferential arrangement is such that the constricting ring 35 is movably mounted on the constricting belt 31, and the constricting belt 31 is fixedly mounted on the wall surface at the corresponding position of the constricting ring 35 away from the inner side wall of the spray control groove 11. When the bottom end of the spray head 12 is adjusted from the upper position of the drill bit 7 side wall to the lower position of the drill bit 7 side wall, the constricting belt 31 will constrict the multi-group combining plates 33 inside the spray head 12, so that the multi-group combining 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 the lower position of the drill bit 7 side wall to the upper position of the drill bit 7 side wall, the constricting belt 31 no longer performs constriction adjustment. At the same time, under the transmission pressure of the cooling liquid in the spray head 12, the multi-group combining plates 33 are separated and opened, thereby reducing the pressure of the cooling liquid transmitted through the spray head 12.

[0041] The working principle of the present invention is:

[0042] When the present invention is used, 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 and fixing plate 6. The control box 4 controls the driving motor and the lifting cylinder inside the equipment box 3 to operate, so that the drill bit 7 drills the parts. The rotation speed of the drill bit 7 causes the counterweight blocks 15 on both sides of the attachment block 9 to be lifted upward by the centrifugal force, and the lifting angle is adapted and changed according to the rotation speed of the drill bit 7. When the counterweight block 15 is lifted, the counterweight block 15 will pull the auxiliary plate 24 to move through the pulling rope 26, so that the movable tooth plate 21 drives the adjustment The gear 23 is adaptively adjusted so that the sprinkler head 12 is adaptively rotated and adjusted through the movable shaft 22, thereby completing the adaptation conditions of the sprinkler angle of the sprinkler head 12. Under the adaptive convergence adjustment of the strength adjustment part, the spray intensity of the sprinkler head 12 is adjusted accordingly, so that the drill bit 7 can be effectively cooled during drilling. At the same time, when the movable tooth plate 21 is adjusted, the waste strip blocking assembly will be adaptively lowered through the adjustment frame, so that the waste strip blocking distance can be effectively adjusted according to the part material, so that the adaptive cooling and waste strip blocking adjustment can be effectively performed for parts of different materials.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
