Description

Technical Field

[0001] The invention relates to the technical field of crankshaft processing, and in particular to a crankshaft processing turning machine tool with intelligent control switching. Background Art

[0002] The crankshaft processing machine tool body is a type of lathe specially used for processing the crankshaft connecting rod neck and crank arm side of internal combustion engines and air compressors. The crankshaft is one of the most important parts in the engine, and its processing accuracy and quality directly affect the performance and life of the engine.

However, the above scheme still has the following shortcomings when it is actually used:

[0004] When turning a crankshaft, it is necessary to spray coolant onto the crankshaft surface, but the crankshaft turning machine tools in the prior art do not have the function of cleaning the crankshaft after turning. Due to the spraying of coolant, the coolant will adhere to the crankshaft surface, and debris will also adhere to the crankshaft surface through the coolant. The crankshaft after turning needs additional cleaning treatment to remove the coolant and debris, which increases production time and cost. In addition, when the crankshaft after turning is removed from the machine tool, the coolant is also easy to drip into the workshop environment.

[0005] Therefore, it is necessary to design a crankshaft turning machine with intelligent control switching to solve the above problems. Summary of the invention

[0026] 3. By setting an L-shaped guide rail and a slider matched therewith, and driving the slider to slide inside the guide rail through a fixed rod during the movement of the push rod, this design cleverly achieves the precise docking of the drive block and the slot and the limit fixation of the rotating ring 1.

By rotating the push rod, the position of the rotating ring 1 can be further fixed. When the slider moves to the end position of the circumferential part, the clamping block and the bayonet are misaligned, and the limit ring acts on the rotating ring to limit the position, thereby ensuring the stability of the position of the transmission shaft and the drive block, and ensuring the transmission stability between the rotating rod and the transmission shaft.

The air suction fan 45 is located inside the air supply cylinder 43, and the air suction fan 45 is fixedly sleeved on the shaft 44. A plurality of air inlets 46 are provided on the air supply cylinder 43. When the driving block 54 is inserted into the slot 34, the power of the rotating rod 31 can be transmitted to the shaft 44, so that the shaft 44 rotates with the rotating rod 31. When the shaft 44 rotates, the air suction fan 45 can perform a suction action and extract ambient air through a plurality of air inlets 46.

[0044] The control unit includes a control component, a limit component and a push component. The control unit is used to control the transmission between the shaft rod 44 and the transmission shaft 53. The control component includes a connecting tube 51, a sliding rod 52, a transmission shaft 53 and a driving block 54. The connecting tube 51 is fixed to one end of the shaft rod 44 located outside the air supply tube 43. The sliding rod 52 is slidably arranged in the connecting tube 51. One end of the sliding rod 52 extends to the outside of the connecting tube 51 and is fixedly connected to the transmission shaft 53.

[0045] The pushing assembly includes a push rod 71, a guide rail 72 and a slider 73. One end of the push rod 71 is connected to the side of the rotating ring 61. The guide rail 72 is fixed to the outer circumference of the air supply cylinder 43. The slider 73 slides in the guide rail 72. The slider 73 is fixed to the end of the push rod 71 away from the rotating ring 61 through a fixing rod 74. The guide rail 72 is an L-shaped structure. The guide rail 72 is composed of an axial portion and a circumferential portion. When the slider 73 moves to the connection position between the axial portion and the circumferential portion, that is, the corner position of the guide rail 72, the driving block 54 is just inserted into the slot 34. In this process, the rotating ring 61 passes through the limit ring 64, and the block 62 also passes through the bayonet 66. When the push rod 71 is rotated, the push rod 71 can drive the rotating ring 61 to rotate. When the rotating ring 61 rotates, the block 62 thereon rotates accordingly. At the same time, the slider 73 will also slide into the circumferential portion. When the slider 73 moves to the end position of the circumferential portion, the block 62 is in a state of being misaligned with the bayonet 66. At this time, the block 62 cannot pass through the bayonet 66. The limiting ring 64 limits the rotating ring 61, that is, the position of the rotating ring 61 is fixed. When the rotating ring 61 is fixed, the positions of the transmission shaft 53 and the driving block 54 are also fixed, thereby ensuring the transmission stability between the rotating rod 31 and the transmission shaft 53.

[0046] The diverter unit includes a diverter assembly and a sliding assembly. The diverter assembly includes a diverter seat 81, two first mounting tubes 82, a second mounting tube 83 and a sliding seat 84. The diverter seat 81 is fixed to the side of the air supply cylinder 43. The two first mounting tubes 82 are arranged on the bottom surface of the diverter seat 81, and the second mounting tube 83 is arranged on the top surface of the diverter seat 81. The two first mounting tubes 82 and the second mounting tube 83 are connected to the inside of the diverter seat 81. The sliding seat 84 is slidably arranged inside the diverter seat 81. One of the first mounting tubes 82 is connected to the air supply pipe, which is connected to the air supply cylinder 43. The second mounting tube 83 is connected to the end of the connecting pipe 24 away from the nozzle 23. The sliding assembly includes a sliding rod 85, a rotating ring 86 and a pull rod 87.

When the rotating ring 86 moves, it will drive the pull rod 87 to move, so that the pull rod 87 pulls the sliding rod 85 to move. When the sliding rod 85 moves, the sliding seat 84 connected thereto moves accordingly. When the driving block 54 is inserted into the slot 34, the sliding seat 84 just moves to a position facing the first mounting pipe 82 connected to the circulation pump. In this case, the sliding seat 84 can block the first mounting pipe 82, and the first mounting pipe 82 connected to the air supply cylinder 43 is in a conducting state. Therefore, the airflow extracted by the suction fan 45 can be discharged into the diverter seat 81, and enter the nozzle 23 through the second mounting pipe 83 and the connecting pipe 24, and finally ejected through the nozzle 23.

[0047] The specific working principle of the present invention is as follows:

[0048] When the crankshaft machining turning machine tool proposed in the present invention is in use, the staff clamps the crankshaft on the machine tool body 12, and the crankshaft clamp 13 provided on the machine tool body 12 is used to clamp the crankshaft. After the clamping is completed, the crankshaft is turned by the machine tool body 12. A coolant supply system is arranged inside the machine tool housing 11, and a circulating pump therein is used to extract the coolant. For the diversion unit, one of the first mounting pipes 82 is connected to the air supply cylinder 43, and the other first mounting pipe 82 is connected to the output end of the above-mentioned circulating pump. During the turning process, the coolant is sprayed out through the nozzle 23 and sprayed on the surface of the crankshaft. It should be noted that the specific structure and working principle of the machine tool body 12, the crankshaft clamp 13 and the coolant supply system are prior art, and the implementation method adopts conventional means, which is not shown in the figure and will not be described in detail here.

[0049] In the initial state, under the elastic force of the connecting spring 63, the driving block 54 is located outside the slot 34, the sliding rod 52 is located outside the connecting tube 51, and the sliding seat is located opposite to the first mounting tube 82 connected to the air supply tube 43, and blocks the first mounting tube 82 connected to the air supply tube 43. The coolant extracted by the circulating pump will be pumped into the diverter seat 81 and enter the nozzle 23 through the second mounting tube 83 and the connecting tube 24. After the processing of the crankshaft is completed, the staff first closes the machine tool body 12, then opens the door panel on the machine tool housing 11, and pushes the push rod 71 to move the push rod 71. When the push rod 71 moves, it can drive the rotating ring 1 61 to move, so that the rotating ring 1 61 drives the transmission shaft 53 to move. When the transmission shaft 53 moves, the driving block 54 connected thereto moves accordingly until the driving block 54 is inserted into the slot 34. In this process, the staff can fine-tune the angle of the fixed block 32 by rotating the fixed block 32 so that the driving block 54 can be smoothly inserted into the slot 34.

[0050] When the driving block 54 is inserted into the slot 34, the staff starts the driving motor 14 again, so that the driving motor 14 drives the rotating shaft 15 to rotate. The rotating shaft 15 and the rotating rod 31 are connected by the transmission member 33. Therefore, the rotating shaft 15 can drive the rotating rod 31 to rotate through the transmission member 33, so that the rotating rod 31 drives the fixed block 32 to rotate. Since the driving block 54 has been inserted into the slot 34, and the cross-sections of the slot 34 and the driving block 54 are both rectangular structures, the fixed block 32 can drive the driving block 54 to rotate, so that the transmission shaft 53 rotates. When the transmission shaft 53 rotates, , the transmission shaft 53 can drive the sliding rod 52 to rotate. Since the cross-sections of the sliding rod 52 and the connecting tube 51 are both rectangular structures, the sliding rod 52 and the connecting tube 51 will rotate along with the transmission shaft 53, and the power will eventually be transmitted to the shaft 44 connected to the connecting tube 51. Based on the above process, when the driving block 54 is inserted into the slot 34, the power of the rotating rod 31 can be transmitted to the shaft 44, so that the shaft 44 rotates along with the rotating rod 31. When the shaft 44 rotates, the suction fan 45 can perform a suction action and extract ambient air through a plurality of air inlets 46;

[0051] When the transmission shaft 53 moves under the push of the rotating ring 1 61, the transmission shaft 53 can also drive the rotating ring 2 86 to move. When the rotating ring 2 86 moves, it will drive the pull rod 87 to move, so that the pull rod 87 pulls the sliding rod 85 to move. When the sliding rod 85 moves, the sliding seat 84 connected thereto moves accordingly. When the driving block 54 is inserted into the slot 34, the sliding seat 84 just moves to a position facing the first mounting pipe 82 connected to the circulation pump. In this case, the sliding seat 84 can block the first mounting pipe 82, and the first mounting pipe 82 connected to the air supply cylinder 43 is in a conducting state. Therefore, the airflow extracted by the suction fan 45 can be discharged into the diverter seat 81 and enter the nozzle 23 through the second mounting pipe 83 and the connecting pipe 24. In the process, the gas is finally ejected through the nozzle 23. In summary, when the machine tool body 12 is reopened, the crankshaft clamp 13 can drive the processed crankshaft to rotate at a high speed. At the same time, the nozzle 23 can spray gas toward the surface of the crankshaft. The residual coolant and debris attached to the surface of the crankshaft will be thrown out under the action of centrifugal force. The gas ejected by the nozzle 23 can also blow away the residual coolant and debris attached to the surface of the crankshaft, so as to clean the crankshaft. In addition, the staff can synchronously start the linear drive 21, so that the linear drive 21 drives the linear slide 22 to reciprocate, and then the nozzle 23 reciprocates. In the process of the nozzle 23 reciprocating above the crankshaft, it can evenly and comprehensively spray gas to the crankshaft, so as to ensure the cleaning effect of the crankshaft.

[0052] It should be noted that during the movement of the push rod 71, the slider 73 can be driven to move through the fixed rod 74, so that the slider 73 slides inside the guide rail 72. The guide rail 72 is an L-shaped structure, and the guide rail 72 is composed of an axial portion and a circumferential portion. When the slider 73 moves to the connection position between the axial portion and the circumferential portion, that is, the corner position of the guide rail 72, the drive block 54 is just inserted into the slot 34. In this process, the rotating ring 61 passes through the limit ring 64, and the block 62 also passes through the bayonet 66. Further, the staff rotates the push rod 71, and the rotation of the push rod 71 can drive the rotating ring 61 to rotate. When the slider 73 moves to the end position of the circumferential portion, the block 62 is misaligned with the bayonet 66. At this time, the block 62 cannot pass through the bayonet 66. The limit ring 64 limits the rotating ring 61, that is, the position of the rotating ring 61 is fixed. When the rotating ring 61 is fixed, the positions of the transmission shaft 53 and the driving block 54 are also fixed, thereby ensuring the transmission stability between the rotating rod 31 and the transmission shaft 53. When the limit needs to be released, the staff only needs to reverse and pull back the push rod 71.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
