Description

Technical Field

[0001] The invention relates to the technical field of crankshaft drilling, and in particular to a crankshaft drilling device for machining automobile parts. Background Art

[0002] The crankshaft is a commonly used automotive component and the most important part of the engine. It is mainly used to bear the force transmitted by the connecting rod and convert it into torque output, and drive other accessories on the engine to work. When the crankshaft is in use, it is subjected to the combined effects of the rotating centrifugal force, the periodically changing gas inertia force and the reciprocating inertia force, so that the crankshaft is subjected to bending and torsional loads. Therefore, the crankshaft needs to be well lubricated when in use, usually by drilling holes on the shaft surface to achieve lubrication;

[0003] When drilling a crankshaft, due to the curved surface of the crankshaft, the drill bit is prone to slipping when in contact with the crankshaft, causing scratches on the crankshaft surface or even deviation of the drilling position. When drilling, if the crankshaft is not fixed, the crankshaft is prone to move, which can easily cause the drill bit to break. Therefore, we proposed a crankshaft drilling equipment for automotive parts processing. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a crankshaft drilling device for automobile parts processing, comprising:

[0005] A base plate, and a slide cylinder disposed on the top of the base plate;

[0006] A drilling mechanism having a feeding structure for drilling a crankshaft;

[0007] A fixing mechanism, the fixing mechanism adjustment structure is used to fix crankshafts of different sizes;

[0008] The top of the bottom plate is fixedly connected to the bottom of the slide cylinder, the drilling mechanism is fixedly connected to the side of the slide cylinder away from the bottom plate, the bottom of the fixing mechanism is fixedly connected to the top of the bottom plate, and the fixing mechanism is arranged on the side of the bottom plate away from the slide cylinder;

[0009] Wherein, the drilling mechanism comprises:

[0010] A drill bit, which is set at an angle and is used to drill from the side of the crankshaft;

[0011] A drive assembly having a transmission structure for driving the drill bit to rotate and feed;

[0012] The drive assembly is fixedly connected to a side of the slide cylinder away from the base plate, and the drill bit is fixedly connected to a side of the drive assembly away from the slide cylinder. The crankshaft is fixed by a fixing mechanism, and then the slide cylinder is started. The slide cylinder drives the drive assembly and the drill bit to move, and the drilling position is adjusted. After adjusting to a predetermined position, the drive assembly drives the drill bit to rotate and feed. The drill bit faces the crankshaft axis and drills at an angle to complete the drilling. The drill bit is set at an angle. Compared with vertical drilling, the drill bit may slide to both sides. The inclined drill bit only tends to slide to one side. The drill bit is easier to control and can avoid offset during drilling. The drilling position is on the side of the crankshaft, and the chips fall under the action of gravity, which can avoid chips remaining on the crankshaft surface and affecting the observation of crankshaft drilling.

[0013] Furthermore, a groove is provided on the side of the drill bit away from the driving assembly, the groove is inclined, and a plurality of grooves are provided along the circumference of the drill bit, and an anti-sliding block is provided in the center of the plurality of grooves, the anti-sliding block is fixedly connected to the side of the drill bit away from the driving assembly, and the anti-sliding block is arranged in a cross shape. When drilling, the anti-sliding block first contacts the crankshaft, and the anti-sliding block first drills a small hole in the crankshaft to determine the drilling position, and limits the drill bit inside the drilled small hole to avoid slipping, and then the position where the groove is provided on the drill bit is used to drill the small hole. The chips are then pushed out of the groove and discharged along the groove, and then contact the threads of the drill bit. Due to the different threads of the groove and the drill bit, the two sides of the long chips are subjected to different forces, resulting in twisting and eventually breaking, thus preventing the drill bit from being stuck inside the crankshaft, and avoiding large chips during drilling, avoiding chips from entangled in the drill bit, and avoiding entangled chips from flying out and injuring people under the action of centrifugal force.

[0014] Furthermore, the driving assembly includes a plate body, which is arranged on a side of the slide cylinder away from the base plate, and a mounting seat is fixedly connected to the side of the plate body away from the slide cylinder, and a telescopic column is fixedly connected to the side of the mounting seat away from the plate body, and the inner wall of the telescopic column away from the mounting seat is fixedly connected to the surface of the drill bit, and the telescopic column is started, and the telescopic column drives the drill bit to feed, and the drill bit contacts the crankshaft, and then drives the drill bit to rotate to complete the drilling.

[0015] Furthermore, a sleeve plate is provided on the outside of the telescopic column, and the inner wall of the sleeve plate is slidably connected to the surface of the telescopic column. The end of the sleeve plate away from the telescopic column is fixedly connected to the side of the mounting seat close to the drill bit. When drilling, the telescopic column slides inside the sleeve plate, and the sleeve plate, the mounting seat and the telescopic column form a triangle. The triangle is stable and can prevent the telescopic column from shaking during drilling, thereby preventing the drill bit from breaking inside the crankshaft.

[0016] Furthermore, a receiving groove is provided at one end of the telescopic column away from the mounting seat, a spring is fixedly connected to the bottom of the receiving groove, an end of the spring close to the drill bit is fixedly connected to a motor, a side of the motor away from the spring is fixedly connected to an end of the drill bit located inside the receiving groove, and the drill bit is fixedly connected to an output end of the motor, the surface of the drill bit is rotatably connected to the inner wall of the receiving groove, the motor is started, and the output end of the motor drives the drill bit to rotate, thereby completing the rotational feed, when the drill bit rotates, the motor vibrates, thereby driving the spring to vibrate, and the spring consumes the energy of the motor vibration, thereby reducing the vibration generated by the motor during drilling, avoiding shaking of the drill bit during drilling, and thus improving the drilling quality.

[0017] Furthermore, the fixing mechanism includes a mounting plate, which is fixedly connected to the top of the base plate, and the mounting plate is arranged on a side of the base plate away from the slide cylinder, and a fixing plate is symmetrically arranged on the side of the mounting plate away from the base plate, and the two fixing plates are rotatably connected to the side of the mounting plate away from the base plate through a rotating rod, and the two fixing plates are cylindrical, and the two sides of the fixing plates away from the base plate are arranged in a tooth shape, and the two sides of the fixing plates away from the mounting plate are engaged with each other, and fixing components are symmetrically arranged on both sides of the mounting plate, and a transmission component is symmetrically arranged at the interval between the two fixing components, and the transmission component drives the fixing plate to move, and the two fixing plates rotate around the mounting plate. After the crankshaft is placed, the transmission component drives the fixing plate to close again to clamp and fix the crankshaft, and the fixing plates that are toothed and engaged with each other are not easy to loosen after being fixed, thereby avoiding radial shaking of the crankshaft and ensuring drilling accuracy.

[0018] Furthermore, a V-shaped plate is fixedly connected to the inner side surface of the fixed plate, and the V-shaped plates are symmetrically arranged in two groups, and the openings of the two groups of V-shaped plates are arranged opposite to each other, and each group of the V-shaped plates is provided with a plurality of V-shaped plates, and the plurality of V-shaped plates are evenly distributed along the circumference of the fixed plate. The V-shaped plate is made of rubber material, and the V-shaped plate first contacts the crankshaft. The rubber V-shaped plate can increase the friction between the crankshaft and the drill bit to prevent rotation when the drill bit is tilted to drill the crankshaft, thereby preventing the drill bit from breaking. The V-shaped plate can prevent the crankshaft from moving along its circumference, and the two V-shaped plates facing the openings can further prevent the crankshaft from moving to both sides along its axial direction, further preventing the crankshaft from breaking due to movement of the crankshaft.

[0019] Furthermore, the transmission assembly includes a telescopic rod, and a telescopic rod is provided on the side of the two fixed plates away from each other, the telescopic rod is fixedly connected to the side of the mounting plate away from the bottom plate, the end of the telescopic rod away from the mounting plate is fixedly connected to a rotating block, the side of the rotating block away from the telescopic rod is rotatably connected to a rotating seat through a rotating rod, and the side of the rotating seat away from the rotating block is fixedly connected to the surface of the fixed plate, and the telescopic rod is started, and the telescopic rod is extended and retracted, driving the rotating block to rise and fall, driving the rotating seat to rise and fall, and at the same time the two rotate with each other, thereby driving the two fixed plates to open and close, thereby completing the fixation of the crankshaft.

[0020] Furthermore, the fixing assembly includes a fixing seat, the fixing seat is fixedly connected to the top of the base plate, the inner wall of the fixing seat is fixedly connected with a bent plate, the bent plate is arranged along the circumferential direction of the inner side surface of the fixing seat, a gasket is fixedly connected on one side of the bent plates close to each other, and the gasket is made of rubber material and is arranged in a wave shape. The crankshaft is inserted into the fixing seat, the crankshaft squeezes the bent plate, the bent plate is deformed, and the crankshaft is clamped. The bent plates limit the crankshaft to the axis center of the inner side surface of the fixing seat, thereby completing pre-fixation. The gasket contacts the crankshaft, and the gasket made of rubber material can increase the friction between the crankshaft and the rubber gasket, thereby preventing the crankshaft from moving after pre-fixation. The wave-shaped gasket can also provide greater resistance in the circumferential direction of the crankshaft to prevent the crankshaft from rotating and deviating during pre-fixation. The two symmetrically arranged fixing assemblies have bent plates that are also symmetrical with each other, and can provide relative oblique extrusion pressure for both sides of the crankshaft, thereby preventing the crankshaft from axially deviating during pre-fixation, ensuring the stability of the fixed position and avoiding affecting the drilling position.

[0021] The second support plate is fixedly connected to the first support plate at one side away from the gasket, and the second support plate is fixedly connected to the inner wall of the fixing seat at one side of the first support plate, and the second support plate is fixedly connected to the second support plate at one side close to the mounting plate, and the second support plate is fixedly connected to the second support plate at one side away from the first support plate, and the first support plate and the second support plate are bent toward the sides away from each other, and the surfaces of the first support plate and the second support plate are penetrated by a groove, and the deformation of the bent plate causes the first support plate and the second support plate to deform toward the sides away from each other, and the first support plate, the second support plate and the bent plate form a triangle, so that when the crankshaft is pre-fixed, the bent plate can be made more stable and the pre-fixation can be avoided from being offset, and the elastic force generated by the deformation of the first support plate and the second support plate can provide support for the bent plate, making the bent plate more firm during pre-fixation, and by providing the groove, the first support plate and the second support plate are more easily deformed, so as to avoid the crankshaft being difficult to insert during pre-fixation.

[0022] The present invention has the beneficial effects:

[0023] 1. The present invention completes drilling by setting a drilling mechanism, with the drill bit facing the crankshaft axis and drilling at an angle. The drill bit is set at an angle, and compared with vertical drilling, the drill bit may slide to both sides, while the drill bit set at an angle only has a tendency to slide to one side, so the drill bit is easier to control and can avoid deviation during drilling. The drilling position is on the side of the crankshaft, and the chips fall under the action of gravity, which can prevent the chips from remaining on the crankshaft surface and avoid affecting the observation of the crankshaft drilling.

[0024] 2. The present invention sets a drill bit and an anti-sliding block to first drill a small hole in the crankshaft, determine the drilling position, limit the drill bit inside the drilled small hole to avoid slipping, and set a groove position for the drill bit to expand the small hole and finally drill out a size that can accommodate the drill bit, pre-drill the small hole, and gradually expand the small hole to complete the limitation of the drill bit. The inclined groove can drive the chips to rotate and be discharged along the inclined groove, and then contact with the thread of the drill bit. Since the threads of the groove and the drill bit are different, the two sides of the long chips are subjected to different forces, thereby causing twisting and eventually breaking, thereby preventing the drill bit from being stuck inside the crankshaft, and avoiding the generation of large chips during drilling, avoiding the chips from entangled with the drill bit, and avoiding the entangled chips from flying out and injuring people under the action of centrifugal force.

[0025] 3. The present invention provides a fixing plate that is toothed and interlocked with each other, so that it is not easy to loosen after being fixed, thereby preventing the crankshaft from shaking in the radial direction and ensuring the drilling accuracy. The V-shaped plate made of rubber material can increase the friction between the crankshaft and the drill bit to prevent the drill bit from rotating when drilling the crankshaft at an angle, thereby preventing the drill bit from breaking. The V-shaped plate can prevent the crankshaft from moving in its circumferential direction, and the two V-shaped plates facing each other at the opening can further prevent the crankshaft from moving to both sides along its axial direction, further preventing the drill bit from breaking due to the movement of the crankshaft.

[0026] 4. The present invention sets bent plates, and several bent plates limit the crankshaft to the axis center of the inner side of the fixing seat, thereby completing pre-fixation. The gasket contacts the crankshaft, and the rubber gasket can increase the friction between the gasket and the crankshaft, thereby preventing the crankshaft from moving after pre-fixation. The wave-shaped gasket can also provide greater resistance in the circumferential direction of the crankshaft to prevent the crankshaft from rotating during pre-fixation. The two symmetrically arranged fixing components have symmetrical bent plates, which can provide relative oblique extrusion pressure on both sides of the crankshaft, thereby preventing the crankshaft from axially offset during pre-fixation, ensuring the stability of the fixing position, and avoiding affecting the drilling position.

[0027] 5. The present invention sets a first support plate. The first support plate, the second support plate and the bent plate form a triangle. When the crankshaft is pre-fixed, the bent plate can be made more stable to avoid displacement caused by pre-fixation. The elastic force generated by the deformation of the first support plate and the second support plate can provide support for the bent plate, making the bent plate more secure during pre-fixation. By providing a groove, the first support plate and the second support plate are more likely to deform, avoiding difficulty in inserting the crankshaft during pre-fixation.

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0039] Example 1, please refer to Figure 1-Figure 5 The present invention is a crankshaft drilling device for automobile parts processing, comprising:

[0040] A base plate 1, and a slide cylinder 2 arranged on the top of the base plate 1;

[0041] A drilling mechanism 3, the drilling mechanism 3 having a feeding structure, for drilling holes in the crankshaft;

[0042] A fixing mechanism 4, the fixing mechanism 4 has an adjustment structure and is used to fix crankshafts of different sizes;

[0043] The top of the bottom plate 1 is fixedly connected to the bottom of the slide cylinder 2, the drilling mechanism 3 is fixedly connected to the side of the slide cylinder 2 away from the bottom plate 1, the bottom of the fixing mechanism 4 is fixedly connected to the top of the bottom plate 1, and the fixing mechanism 4 is arranged on the side of the bottom plate 1 away from the slide cylinder 2;

[0044] Wherein, the drilling mechanism 3 comprises:

[0045] A drill bit 31, which is tilted and used for drilling from the side of the crankshaft;

[0046] A driving assembly 32, the driving assembly 32 having a transmission structure for driving the drill bit 31 to rotate and feed;

[0047] The drive assembly 32 is fixedly connected to the side of the slide cylinder 2 away from the base plate 1, and the drill bit 31 is fixedly connected to the side of the drive assembly 32 away from the slide cylinder 2. The crankshaft is fixed by the fixing mechanism 4, and then the slide cylinder 2 is started. The slide cylinder 2 drives the drive assembly 32 and the drill bit 31 to move, and the drilling position is adjusted. After adjusting to the predetermined position, the drive assembly 32 drives the drill bit 31 to rotate and feed. The drill bit 31 is facing the crankshaft axis and drills in at an angle to complete the drilling. The drill bit 31 is set at an angle. Compared with vertical drilling, the drill bit 31 may slide to both sides. The inclined drill bit 31 only tends to slide to one side. The drill bit 31 is easier to control and can avoid offset during drilling. The drilling position is on the side of the crankshaft. The chips fall under the action of gravity, which can avoid chips remaining on the crankshaft surface and affect the observation of crankshaft drilling.

[0048] A groove 33 is provided on the side of the drill bit 31 away from the driving assembly 32. The groove 33 is inclined and has a plurality of grooves 33 along the circumference of the drill bit 31. Anti-slip blocks 34 are provided at the centers of the plurality of grooves 33. The anti-slip blocks 34 are fixedly connected to the side of the drill bit 31 away from the driving assembly 32 and are arranged in a cross shape. When drilling, the anti-slip block 34 first contacts the crankshaft, and the anti-slip block 34 first drills a small hole in the crankshaft to determine the drilling position, and limits the drill bit 31 inside the drilled small hole to avoid slipping. Then, the drill bit 31 is provided with a groove 33 at the position where the small hole is drilled. The chips are then expanded and finally drilled out to a size that can accommodate the drill bit 31. A small hole is pre-drilled and gradually expanded to complete the positioning of the drill bit 31. The inclined groove 33 can drive the chips to rotate and be discharged along the inclined groove 33, and then contact the threads of the drill bit 31. Since the threads of the groove 33 and the drill bit 31 are different, the two sides of the long chips are subjected to different forces, thereby causing distortion and eventually breaking, thereby preventing the drill bit 31 from being stuck inside the crankshaft, and preventing larger chips from being generated during drilling, preventing the chips from entangled in the drill bit 31, and preventing the entangled chips from flying out and injuring people under the action of centrifugal force.

[0049] The driving assembly 32 includes a plate body 321, which is arranged on the side of the slide cylinder 2 away from the base plate 1. The side of the plate body 321 away from the slide cylinder 2 is fixedly connected to a mounting seat 322, and the side of the mounting seat 322 away from the plate body 321 is fixedly connected to a telescopic column 323. The inner wall of the telescopic column 323 away from the mounting seat 322 is fixedly connected to the surface of the drill bit 31. When the telescopic column 323 is started, the telescopic column 323 drives the drill bit 31 to feed, and the drill bit 31 contacts the crankshaft, and then drives the drill bit 31 to rotate to complete the drilling.

[0050] The outer part of the telescopic column 323 is provided with a sleeve plate 324, the inner wall of the sleeve plate 324 is slidably connected to the surface of the telescopic column 323, and the end of the sleeve plate 324 away from the telescopic column 323 is fixedly connected to the side of the mounting seat 322 close to the drill bit 31. When drilling, the telescopic column 323 slides inside the sleeve plate 324, and the sleeve plate 324, the mounting seat 322 and the telescopic column 323 form a triangle. The triangle is stable and can prevent the telescopic column 323 from shaking during drilling, thereby preventing the drill bit 31 from breaking inside the crankshaft.

[0051] An accommodating groove 325 is provided at one end of the telescopic column 323 away from the mounting seat 322, and a spring 327 is fixedly connected to the bottom of the accommodating groove 325, and an end of the spring 327 close to the drill bit 31 is fixedly connected to a motor 326, and a side of the motor 326 away from the spring 327 is fixedly connected to an end of the drill bit 31 located inside the accommodating groove 325, and the drill bit 31 is fixedly connected to an output end of the motor 326, and the surface of the drill bit 31 is rotatably connected to the inner wall of the accommodating groove 325. When the motor 326 is started, the output end of the motor 326 drives the drill bit 31 to rotate, thereby completing the rotational feeding. When the drill bit 31 rotates, the motor 326 vibrates, thereby driving the spring 327 to vibrate. The spring 327 consumes the energy of the vibration of the motor 326, thereby reducing the vibration generated by the motor 326 during drilling, avoiding shaking of the drill bit 31 during drilling, and thus improving the drilling quality.

[0052] Example 2, please refer to Figure 1-Figure 9 The fixing mechanism 4 includes a mounting plate 41, which is fixedly connected to the top of the base plate 1, and the mounting plate 41 is arranged on the side of the base plate 1 away from the slide cylinder 2. A fixing plate 42 is symmetrically arranged on the side of the mounting plate 41 away from the base plate 1. The two fixing plates 42 are rotatably connected to the side of the mounting plate 41 away from the base plate 1 through a rotating rod. The two fixing plates 42 form a cylindrical shape. The side of the two fixing plates 42 away from the base plate 1 is set to a tooth shape, and the side of the two fixing plates 42 away from the mounting plate 41 is engaged with each other. Fixing components 45 are symmetrically arranged on both sides of the mounting plate 41, and a transmission component 43 is symmetrically arranged at the interval between the two fixing components 45. The transmission component 43 drives the fixing plate 42 to move, and the two fixing plates 42 rotate around the mounting plate 41. After the crankshaft is placed, the transmission component 43 drives the fixing plate 42 to close again, and the crankshaft is clamped and fixed. The fixing plates 42 that are toothed and engaged with each other are not easy to loosen after being fixed, thereby avoiding the crankshaft from shaking along the radial direction and ensuring the drilling accuracy.

[0053] A V-shaped plate 44 is fixedly connected to the inner side surface of the fixed plate 42. Two groups of V-shaped plates 44 are symmetrically arranged, and the openings of the two groups of V-shaped plates 44 are arranged opposite to each other. Each group of V-shaped plates 44 is provided with a plurality of V-shaped plates 44, and the plurality of V-shaped plates 44 are evenly distributed along the circumference of the fixed plate 42. The V-shaped plate 44 is made of rubber material. The V-shaped plate 44 first contacts the crankshaft. The rubber V-shaped plate 44 can increase the friction between the crankshaft and the drill bit 31 to avoid rotation when the drill bit 31 is tilted to drill the crankshaft, thereby avoiding the drill bit 31 from breaking. The V-shaped plate 44 can prevent the crankshaft from moving along its circumference, and the two V-shaped plates 44 facing the opening can further prevent the crankshaft from moving to both sides along its axial direction, further avoiding the crankshaft movement causing the drill bit 31 to break.

[0054] The transmission assembly 43 includes a telescopic rod 431. The telescopic rod 431 is provided on the side of the two fixed plates 42 away from each other. The telescopic rod 431 is fixedly connected to the side of the mounting plate 41 away from the bottom plate 1. The end of the telescopic rod 431 away from the mounting plate 41 is fixedly connected to a rotating block 432. The side of the rotating block 432 away from the telescopic rod 431 is rotatably connected to a rotating seat 433 through a rotating rod. The side of the rotating seat 433 away from the rotating block 432 is fixedly connected to the surface of the fixed plate 42. When the telescopic rod 431 is started, the telescopic rod 431 is extended and retracted, driving the rotating block 432 to rise and fall, driving the rotating seat 433 to rise and fall, and at the same time, the two rotate with each other, thereby driving the two fixed plates 42 to open and close, thereby completing the fixation of the crankshaft.

[0055] The fixing assembly 45 includes a fixing seat 451, which is fixedly connected to the top of the bottom plate 1. The inner wall of the fixing seat 451 is fixedly connected with a bent plate 452. A plurality of bent plates 452 are arranged along the circumference of the inner side of the fixing seat 451. A gasket 453 is fixedly connected to the side of the plurality of bent plates 452 close to each other, and the gasket 453 is made of rubber material and is set in a corrugated shape. When the crankshaft is inserted into the fixing seat 451, the crankshaft squeezes the bent plate 452, and the bent plate 452 is deformed, thereby clamping the crankshaft. The plurality of bent plates 452 limit the crankshaft to the inner side of the fixing seat 451. The gasket 453 is at the axis center, thereby completing the pre-fixation. The gasket 453 is in contact with the crankshaft. The rubber gasket 453 can increase the friction between the gasket and the crankshaft, thereby preventing the crankshaft from moving after the pre-fixation. The wave-shaped gasket 453 can also provide greater resistance in the circumferential direction of the crankshaft, thereby preventing the crankshaft from rotating and deviating during the pre-fixation. The two symmetrically arranged fixing components 45 have bent plates 452 that are also symmetrical to each other, which can provide relative oblique extrusion pressure for both sides of the crankshaft, thereby preventing the crankshaft from axially deviating during the pre-fixation, ensuring the stability of the fixing position, and avoiding affecting the drilling position.

[0056] The side of the bent plate 452 away from the gasket 453 is fixedly connected to the first support plate 454, the side of the first support plate 454 away from the bent plate 452 is fixedly connected to the inner wall of the fixed seat 451, the side of the first support plate 454 close to the mounting plate 41 is fixedly connected to the second support plate 455, the side of the second support plate 455 away from the first support plate 454 is fixedly connected to the side of the bent plate 452 away from the gasket 453, the first support plate 454 and the second support plate 455 are bent toward the side away from each other, and the surfaces of the first support plate 454 and the second support plate 455 are penetrated with a groove 456, the bent plate 452 is deformed, and the first support plate 45 4 and the second support plate 455, thereby driving the first support plate 454 and the second support plate 455 to deform toward the side away from each other. The first support plate 454, the second support plate 455 and the bent plate 452 form a triangle. When the crankshaft is pre-fixed, the bent plate 452 can be made more stable to avoid deviation caused by the pre-fixation. The elastic force generated by the deformation of the first support plate 454 and the second support plate 455 can provide support for the bent plate 452, making the bent plate 452 more secure during pre-fixation. By providing the groove 456, the first support plate 454 and the second support plate 455 are more likely to deform, avoiding difficulty in inserting the crankshaft during pre-fixation.

[0057] When in use, the crankshaft is inserted into the fixing seat 451, and the crankshaft squeezes the bent plate 452, causing the bent plate 452 to deform. The bent plate 452 deforms, causing the first support plate 454 and the second support plate 455 to deform to the side away from each other, thereby clamping the crankshaft. Subsequently, the bent plate 452 of another fixing component 45 is manually pressed to insert the crankshaft into the other fixing component 45, thereby completing the pre-fixation of the crankshaft. Subsequently, the telescopic rod 431 is started, and the telescopic rod 431 is extended and retracted, driving the rotating block 432 to rise and fall, driving the rotating seat 433 to rise and fall, and at the same time, the two rotate relative to each other, thereby driving The two fixing plates 42 open and close to fix the crankshaft, start the motor 326, and the output end of the motor 326 drives the drill bit 31 to rotate, thereby completing the rotational feeding, start the telescopic column 323, and the telescopic column 323 drives the drill bit 31 to feed, and the drill bit 31 contacts the crankshaft, and then drives the drill bit 31 to rotate. When drilling, the anti-sliding block 34 first contacts the crankshaft, and the anti-sliding block 34 first drills a small hole in the crankshaft to determine the drilling position, and limits the drill bit 31 inside the drilled small hole to avoid slipping. Then the drill bit 31 opens a position with a groove 33 to expand the small hole, and finally drills a size that can accommodate the drill bit 31. After reaching the predetermined depth, the drilling is completed.
