Description

Technical Field

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

[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsion loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.

[0003] Lubrication between the crankshaft and the bearing is an important guarantee for the reliable operation of the engine. The function of the crankshaft oil hole is to connect the oil path between the crankshaft and the bearing, so as to keep the lubricating oil produced by the high-pressure oil pump smoothly through the oil hole to reach the surface of all shafts and form an oil film. In order to meet the needs of crankshaft strength, the crankshaft journal oil hole is designed as an oblique oil hole. The oblique oil hole is oblique to the common plane, and the closed line formed by the intersection of the oblique oil hole and the journal surface is a complex three-dimensional curve.

[0004] Therefore, when drilling the inclined oil hole on the crankshaft, the stability of the fixture needs to be ensured to ensure the accuracy of the drilling of the inclined hole. In order to ensure the accuracy of the drilling, the fixture of the crankshaft is usually more complicated and the disassembly is more cumbersome, which affects the efficiency of the crankshaft drilling. After the crankshaft drilling is completed, the crankshaft with the hole drilled must be removed from the fixture before the next crankshaft to be drilled can be placed on the fixture and then drilled, which is not efficient. For example, Chinese patent CN218341045U discloses a structure for drilling inclined oil holes on a crankshaft. Although it can clamp the crankshaft and drill the oil hole, it still needs to remove the crankshaft from the fixture before drilling the next crankshaft, which is less efficient.

[0005] Therefore, a drilling device for crankshaft production is needed to solve the above problems. Summary of the invention

[0041] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0042] like Figure 1 , 2 As shown in Figures 3, 9 and 12, the embodiments of the present invention disclose a drilling device for crankshaft production, including a base 1, a clamping mechanism 2 is provided on the base 1, a drilling mechanism 3 is provided on the clamping mechanism 2, the clamping mechanism 2 includes a front end clamping member 21 and a rear end clamping member 22, the front end clamping member 21 includes a first mounting plate 211, a first mounting rod 212 is rotatably connected to the middle section of one side of the first mounting plate 211, a second mounting rod 213 is threadedly sleeved on the first mounting rod 212, the second mounting rod 213 is fixedly connected to the base 1, a top plate 214 is threadedly sleeved on the first mounting rod 212, the top plate 214 can abut against the end of the second mounting rod 213, the other side of the first mounting plate 211 is symmetrically rotatably connected to two mounting sleeves 215, the front end of the crankshaft can be inserted into the mounting sleeve 215; the rear end clamping member 22 includes a flip motor 221, the flip motor 221 is fixedly connected to the base 1, the output end of the flip motor 221 is fixedly connected with a second mounting plate 222, a telescopic rod 23 is connected between the second mounting plate 222 and the first mounting plate 211, and the two ends of the second mounting plate 222 are respectively hinged with connecting blocks 223, and a connecting plate 224 is slidably connected to the connecting block 223 along the axis direction of the output end of the flip motor 221, and the rear end of the crankshaft can be connected to the connecting plate 224 by bolts, and a push rod 225 is connected to the flip motor 221 through an L-shaped rod, and when one of the connecting plates 224 is parallel to the second mounting plate 222, the push rod 225 abuts against a side of the connecting plate 224 away from the front end clamping member 21.

[0043] Specifically, when in use, the connecting plate 224 away from the push rod 224 is flipped in the direction away from the front end clamping piece 21 to a 90° position with the second mounting plate 222, and then the rear end of the crankshaft is mounted on the connecting plate 224 by bolts, and then the connecting plate 224 is reset to a position parallel to the second mounting plate 222, and at the same time, the connecting plate 224 is slid to a position closest to the front end clamping piece 21, and then the first mounting rod 212 is rotated. Due to the threaded cooperation between the first mounting rod 212 and the second mounting rod 213, The first mounting rod 212 drives the mounting sleeve 215 to be sleeved on the front end of the crankshaft, and then the top plate 214 is rotated. Due to the threaded cooperation between the top plate 214 and the first mounting rod 212, the top plate 214 abuts against the end of the second mounting rod 213. Then, the motor 221 is started, so that the output end of the motor 221 drives the second mounting plate 222 to rotate. When the second mounting plate 222 flips 180°, the motor 221 is stopped, and at the same time, the top rod 225 abuts against the connecting plate 224 at the rear end of the crankshaft. Then, the drilling mechanism 3 is started to drill. The hole mechanism 3 drills a hole in the crankshaft; while the hole mechanism 3 is drilling a hole in the crankshaft, the connecting plate 224 away from the push rod 225 is flipped 90 degrees, and the connecting plate 224 is moved to the position closest to the flip motor 221, and then the rear end of another crankshaft of the same specification is installed on the connecting plate 224 away from the push rod 225 by bolts, and then the connecting plate 224 is flipped so that the connecting plate 224 is parallel to the second mounting plate 222, and then the connecting plate 224 is pushed so that the connecting plate 224 drives the crankshaft to move closer to the front The end clamp 21 moves in the direction of the crankshaft so that the front end of the crankshaft is inserted into the mounting sleeve 215; after the previous crankshaft is drilled, the flip motor 221 is started, and the output end of the flip motor 221 drives the crankshaft with the drilled hole to flip downward. When the second mounting plate 222 flips 180°, the flip motor 221 is stopped. At this time, the other crankshaft rotates to the lower side of the drilling mechanism 3, and then the drilling mechanism 3 is started to drill the crankshaft. At the same time, the crankshaft with the drilled hole is removed, and a new crankshaft of the same specification is installed, and the above actions are repeated.

[0044] Through the setting of the front end clamping piece 21 and the rear end clamping piece 22, the crankshaft can be clamped to facilitate the drilling of the drilling mechanism 3; and two crankshafts can be clamped at the same time. At the same time, through the sliding setting of the connecting plate 224 and the connecting block 223 and the hinged setting of the connecting block 223 and the second mounting plate 222, while drilling one of the crankshafts, the other crankshaft can be installed or removed without affecting the clamping of the crankshaft being drilled; and through the setting of the flipping motor 221, after the crankshaft drilling is completed, the other crankshaft to be drilled can be rotated to the lower side of the drilling mechanism 3, and the crankshaft that has been drilled can be moved away, thereby achieving the effect of clamping the next crankshaft while drilling, so that the drilling equipment can continuously drill the crankshaft, greatly improving the production efficiency.

[0045] like Figure 1 , 2 As shown in Figures 9 and 10, two protection mechanisms 4 are centrally symmetrically arranged on the telescopic rod 23, one of which is located directly below the drilling mechanism 3, and the other is located below the clamping mechanism 2. The protection mechanism 4 includes a protection box 41 arranged on the telescopic rod 23, and the top of the protection box 41 is open. When the crankshaft is clamped between the front clamping piece 21 and the rear clamping piece 22, the crankshaft is located in the protection box 41. The protection box 41 includes an inner box body 411 and an outer box body 412. The inner box body 411 is inserted into the outer box body 412, and the inner box body 411 is slidably connected to the outer box body 412. The inner box body 411 and the outer box body 412 are respectively connected to the two ends of the telescopic rod 23.

[0046] Specifically, during use, when the drilling mechanism 3 drills a hole in the crankshaft, since the crankshaft is located in the protective box 41, the debris generated by the drilling will be blocked by the protective box 41 to prevent the debris from flying around, polluting the working environment, and affecting the operator's operation; when the front end clamping piece 21 moves to adapt to crankshafts of different specifications, the front end clamping piece 21 drives the inner box body 411 and the outer box body 412 to slide through the telescopic rod 23, thereby expanding the volume of the protective box 41 to adapt to crankshafts of different specifications.

[0047] By setting up the protection box 41, the debris generated by drilling can be blocked when the crankshaft is drilled, preventing the debris from flying around, polluting the working environment, and affecting the operator's operation; at the same time, the sliding connection between the inner box body 411 and the outer box body 412 can adapt to crankshafts of different specifications, thereby improving the applicability of the equipment.

[0048] like Figure 6 , 7 As shown in , 11, and 13, the side of the protection box 41 away from the telescopic rod 23 is composed of a telescopic plate, and the telescopic plate includes an outer plate 413 and an inner plate 414, the inner plate 414 is inserted into the outer plate 413, and the inner plate 414 is slidably connected to the outer plate 413, and the end of the inner plate 414 is hinged to the inner box body 411, and the end of the outer plate 413 is hinged to the outer box body 412, and the outer plate 413 is hinged to the outer box body A torsion spring 415 is provided at the hinge of 412, and a rotating motor 42 is fixedly connected to a side of the inner box 411 close to the rear end clamping piece 22. A winding wheel 43 is fixedly provided on the output end of the rotating motor 42, and a pull rope 44 is wound around the winding wheel 43. The pull rope 44 is fixedly connected to the end of the inner plate 414. When the torsion spring 415 is not storing force, the inner plate 414 and the outer plate 413 are parallel to the bottom surface of the inner box 411.

[0049] Specifically, when in use, when the protection box 41 is located on the upper side of the front clamping piece 21 and the rear clamping piece 22 of the crankshaft to be installed, the inner plate 414 and the outer plate 413 are kept parallel to the top surface of the inner box body 411 under the action of the torsion spring 415, so that the operator can clamp the crankshaft between the front clamping piece 21 and the rear clamping piece 22 conveniently; when the crankshaft is clamped and needs to be flipped to the lower side of the drilling mechanism 3, the rotating motor 42 is started, and the output end of the rotating motor 42 drives the winding wheel 43 to rotate, and the winding wheel 43 winds the pull rope 44 around the winding wheel 43, the pull rope 44 drives the telescopic plate to approach the telescopic rod 23, and at the same time accumulates force on the torsion spring 415, so that the protection box 41 is closed. After the protection box 41 is closed, the rotating motor 42 stops rotating. When the crankshaft is drilled and needs to be flipped downward, the rotating motor 42 is started, and the rotating motor 42 drives the winding wheel 43 to loosen the pull rope 44. Under the action of the torsion spring 415, the telescopic plate is flipped in the direction away from the telescopic rod 23, and during the downward flipping process, the drilling debris collected in the protection box 41 slides down along the telescopic plate and out of the protection box 41.

[0050] Through the hinged setting of the telescopic plate and the protection box 41, when the drilling mechanism 3 processes the crankshaft, the telescopic plate can close the protection box 41 to prevent the drilling debris collected therein from flying out and affecting the operating environment; after the drilling is completed, the telescopic plate can open the protection box 41 to allow the debris therein to slide to the lower side, making it easier to collect the debris, and the opening of the telescopic plate can avoid affecting the removal of the crankshaft and the clamping of the next crankshaft.

[0051] like Fig. 9 As shown, the telescopic rod 23 includes a rod sleeve fixedly connected to the first mounting plate 211, a rod body is slidably connected in the rod sleeve, an end of the rod body is fixedly connected to the second mounting plate 222, the inner box 411 is fixedly connected to the rod body, and the outer box 412 is fixedly connected to the rod sleeve.

[0052] Specifically, when the first mounting plate 211 moves, the first mounting plate 211 drives the rod sleeve to move, and the rod sleeve slides on the rod body.

[0053] By disposing the telescopic rod 23, the first mounting plate 211 and the second mounting plate 222 do not rotate relative to each other, which facilitates the installation of the crankshaft.

[0054] like Figure 1 , 3 As shown, a collecting mechanism 5 is provided on the base 1, and the collecting mechanism 5 includes a collecting box 51 with a top opening provided on the base 1, and eight abutment rods 52 are fixedly connected to the collecting box 51 at equal intervals, and the abutment rods 52 can abut against the telescopic plate.

[0055] Specifically, during use, when the protection box 41 is flipped downward and the telescopic plate moves away from the telescopic rod 23, the end of the telescopic plate abuts against the abutment rod 52. The telescopic plate vibrates continuously during the process of sequential abutment with the eight abutment rods 52, which facilitates the discharge of debris in the protection box 41.

[0056] The collection mechanism 5 is provided to collect drilling debris, and the abutment between the abutment rod 52 and the telescopic plate causes the telescopic plate and the protection box 41 to vibrate, thereby facilitating the discharge of drilling debris.

[0057] like Figure 4 , 7 As shown, a rubber pad 45 is provided at the bottom of a side of the telescopic plate away from the telescopic rod 23 , and the rubber pad 45 can close the gap between the bottom of the telescopic plate and the protection box 41 .

[0058] Specifically, the rubber pad 45 can close the gap between the bottom of the telescopic plate and the protection box 41 to prevent debris from scattering from the bottom hinge gap between the telescopic plate and the protection box 41. At the same time, due to the soft properties of the rubber pad 45, it does not affect the flipping of the telescopic plate relative to the protection box 41.

[0059] like Figure 2 , 3 As shown, the drilling mechanism 3 includes two driving motors 31 fixedly connected to the top of the base 1, and the output end of each driving motor 31 is fixedly connected to a screw 32, and each screw 32 is threadedly sleeved with a thread block 33. The two thread blocks 33 are fixedly connected by a connecting rod, and the two screws 32 are parallel, and the plane where the two screws 32 are located is perpendicular to the horizontal plane, and the axial direction of the screw 32 is parallel to the horizontal plane.

[0060] Specifically, when in use, when the drilling mechanism 3 needs to move in the horizontal direction, the drive motor 31 is started, and the output end of the drive motor 31 drives the screw 32 to rotate. The rotation of the screw 32 drives the threaded block 33 to move in the horizontal direction, thereby drilling holes on different axial directions of the crankshaft.

[0061] like Figure 3 , 4 As shown, the drilling mechanism 3 also includes a steering motor 34 fixedly connected to the connecting rod, the output end of the steering motor 34 is fixedly connected to a steering plate 35, the output end of the steering motor 34 passes through the connecting rod, the output end of the steering motor 34 is rotatably connected to the connecting rod, and two electromagnetic slide rails 36 are symmetrically fixedly connected to the steering plate 35, and an electromagnetic slider is slidably connected in each of the electromagnetic slide rails 36.

[0062] Furthermore, the electromagnetic slider and the electromagnetic slide rail are prior art and will not be described in detail.

[0063] Specifically, during use, when the drilling mechanism 3 needs to turn, the steering motor 34 is started, and the output end of the steering motor 34 drives the steering plate 35 to rotate, and the steering plate 35 drives the electromagnetic slide rail 36 to rotate, thereby realizing the change of drilling direction; when drilling is required, the electromagnetic slide rail 36 is started, so that the electromagnetic slider therein moves toward the direction close to the crankshaft; when the protection box 41 needs to be flipped, the electromagnetic slide rail 36 is started, so that the electromagnetic slider therein moves toward the direction away from the crankshaft, so as to facilitate the flipping of the protection box 41.

[0064] like Figure 4 , 5 As shown in 10, the drilling mechanism 3 also includes a mounting frame 37 fixedly connected between the two electromagnetic sliders, a drill changing motor is fixedly connected to the mounting frame 37, an output end of the drill changing motor is fixedly connected to a mounting plate 38, the mounting plate 38 is hexagonal, and six mounting grooves are evenly opened on the side surface of the mounting plate 38 along the circumferential direction, an electric push rod 39 is fixedly connected in each of the mounting grooves, and a drilling motor 310 is fixedly connected to the output end of each of the electric push rods 39, and a drill bit 311 is detachably connected to the output end of the drilling motor 310.

[0065] Furthermore, the electric push rod 39 is a prior art and will not be described in detail; except for the drilling motor 310, the other motors are self-locking motors, that is, after the motor stops moving, the motor output end does not rotate under the action of external force. The self-locking motor is a prior art and will not be described in detail.

[0066] Specifically, when it is necessary to drill a hole in the crankshaft during use, the electric push rod 39 and the drilling motor 310 are started, and the output end of the drilling motor 310 drives the drill bit 311 to rotate, and the drill bit 311 drills a hole in the crankshaft, and under the action of the electric push rod 39, the drill bit 311 is driven to move toward the inside of the crankshaft.

[0067] like Fig.12 As shown, the connecting block 223 and the connecting plate 224 are slidably connected via a slide rail and a slider, and two slide rails are symmetrically arranged on the connecting block 223, and the slide rails are T-shaped slide rails. A slider is slidably connected in each of the slide rails, and the slider is a T-shaped slider, and the slider is fixedly connected to the connecting plate 224.

[0068] Specifically, when in use, when the connecting plate 224 and the connecting block 223 need to slide relative to each other, the connecting plate 224 is moved, and the connecting plate drives the sliding block to slide in the sliding rail.
