Description

Technical Field

[0001] This invention relates to the field of polishing technology, specifically to a polishing device for automotive crankshaft processing. Background Technology

[0002] With the continuous advancement of technology and the rapid development of society, the automotive industry is also advancing rapidly, and its applications in automobiles are increasing. The automobile crankshaft is a core power transmission component of the engine, often referred to as the "heart of the engine." The piston generates reciprocating linear motion through the expansion of combustion gases, pushing the big end of the connecting rod to swing. The small end of the connecting rod then drives the crankshaft's crankpin to rotate, ultimately converting linear motion into continuous rotational power, which is transmitted to the transmission, wheels, and other subsequent drive systems. An automobile crankshaft generally consists of a main journal and a crankshaft journal. Automobile crankshaft machining and grinding equipment is used to perform surface grinding on automobile crankshafts to ensure their surface quality and dimensional accuracy.

[0003] Currently, the crank journal axis is in an off-center position. When grinding existing automotive crankshafts, the misalignment between the crank journal axis and the crankshaft axis makes it inconvenient to grind the outer side of the crank journal when controlling the rotation of the crankshaft. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: An automotive crankshaft machining and grinding device, comprising: The machine body, and a rotary drive fixedly installed on the top side of the machine body, a chuck fixedly installed at the output end of the rotary drive, a bracket fixedly installed on the side of the surface of the machine body, and a support mechanism installed at the top of the machine body and at the end away from the rotary drive. The processing mechanism includes a linear actuator and a connecting slider. The linear actuator is fixedly mounted on the top of the bracket, and the connecting slider is fixedly mounted on the output end of the linear actuator. A frame is fixedly mounted on the side of the surface of the connecting slider, and a hydraulic cylinder is mounted on the side of the top of the connecting slider. A grinding component is mounted at the center of the frame. By moving the output end of the linear actuator, a driving force can be applied to the connecting slider, which can drive the hydraulic cylinder and the grinding component to move linearly together. The overall position of the grinding component can be adjusted to facilitate grinding of the crank neck at different positions. The grinding assembly includes a square guide post and connecting teeth. The square guide post is slidably mounted at the center of the frame. The telescopic end of the hydraulic cylinder is fixedly mounted between the telescopic end and the side of the square guide post. A driven wheel is rolled on the end of the connecting teeth away from the square guide post. A support spring is fixedly connected to the middle of the surface of the connecting teeth. A drive wheel is rolled on the middle of the interior of the square guide post. A grinding belt is installed between the driven wheel and the drive wheel. A servo motor is fixedly mounted on the surface of the square guide post near the drive wheel. By extending the output end of the hydraulic cylinder, a pushing force can be applied to the square guide post. With the support of the frame, the square guide post is pushed towards the position close to the crankshaft. With the connection of the connecting teeth, the position of the grinding belt can be adjusted. By retracting the output end of the hydraulic cylinder, a reverse pulling force can be applied to the square guide post, causing the grinding belt to move away from the crank neck. When the crankshaft rotates, it is easy to adapt to the eccentric rotation of the crank neck, control the distance between the grinding belt and the crank neck, and facilitate effective grinding.

[0005] Preferably, the linear actuator is installed parallel to the machine body, and the surface of the connecting slider is in contact with the inner side of the linear actuator.

[0006] Preferably, the connecting teeth are installed at an angle, and there are two connecting teeth, which are symmetrically installed along the central axis of the square guide post.

[0007] The grinding belt is supported by two connecting teeth, and the two symmetrical connecting teeth form a V-shaped opening. The connecting teeth extend between two sets of symmetrical cranks. After the grinding belt contacts the surface of the crank neck, the grinding belt can become an arc-shaped bend, which is convenient to adapt to crank necks of different diameters. By using the rotation of the output end of the servo motor, the drive wheel can be driven to rotate, and under the rolling support of the driven wheel, the grinding belt can run to grind the surface of the crank neck.

[0008] Preferably, the end of the drive wheel central shaft is fixedly installed to the output end of the servo motor via a coupling, and the support spring is a wavy curved surface.

[0009] Preferably, the support mechanism includes a rectangular hole, a guide groove, and a lead screw actuator. The rectangular hole is located on the top side of the machine body surface, the guide groove is located on the top side of the machine body, the lead screw actuator is mounted on the surface of the machine body near the rectangular hole, and the lead screw of the lead screw actuator extends into the interior of the machine body. An I-shaped block is slidably mounted on the surface of the machine body through the rectangular hole. A herringbone frame is fixedly mounted on the surface of the I-shaped block. A ball bearing is rotatably mounted on the bottom of the herringbone frame near the guide groove, and a conical centering cap is rotatably mounted on the top of the herringbone frame. An anti-slip strip is fixedly connected to the conical surface on the inner side of the conical centering cap. One end of the automobile crankshaft is fixed by the jaws on the chuck surface. By rotating the lead screw at the end of the lead screw pusher, the I-shaped block can be driven to slide. With the support of the herringbone frame, the conical centering cap can move linearly, thereby adjusting the distance between the conical centering cap and the chuck. This allows it to accommodate automobile crankshafts of different lengths and supports the end of the automobile crankshaft away from the chuck. The central axis of the automobile crankshaft coincides with the axis of the chuck, thereby centering the automobile crankshaft and making the rotation of the automobile crankshaft more stable.

[0010] Preferably, the I-shaped block is threadedly installed between itself and the surface of the lead screw of the lead screw pusher. There are two I-shaped blocks, and the two I-shaped blocks are symmetrically installed along the central axis of the machine body.

[0011] By using rolling balls to move within the guide groove, rolling friction is employed, which allows the herringbone frame to drive the conical centering cap to move smoothly and prevents jamming. Furthermore, anti-slip strips are evenly distributed on the inner side of the conical centering cap, increasing friction when the end of the crankshaft furthest from the chuck contacts the anti-slip strips, thus preventing slippage.

[0012] Preferably, the spherical surface at the bottom of the ball is embedded inside the guide groove, and the anti-slip strips are evenly distributed on the conical surface inside the conical centering cap.

[0013] Preferably, a dust removal mechanism is installed on the top of the connecting slider. The dust removal mechanism includes a dust filter. The bottom of the dust filter is fixedly installed on the top of the connecting slider via a Z-shaped base. A support spring is fixedly installed on the side of the surface of the dust filter. A cylinder is rotatably installed at the end of the support spring away from the dust filter. Rotary connectors are installed at both ends of the surface of the support spring. A through hole is opened in the middle of the outer surface of the cylinder. A suction fan is fixedly installed in the middle of the surface of the dust filter. An air pipe is connected between the air inlet of the suction fan and the end of the rotary connector away from the cylinder. The cylinder is supported by the support spring, and under the action of the cylinder's own weight, the surface of the cylinder is in contact with the surface of the grinding belt. When the grinding belt is running, the cylinder rolls, which can support the grinding belt and make it less prone to jumping. The grinding belt runs stably during grinding. When the cylinder is rolling, both ends of the cylinder are connected to the air pipe through rotating connectors, which makes the cylinder run smoothly and prevents the structure from getting stuck.

[0014] Preferably, the support spring is arc-shaped, there are two support springs, and the two support springs are symmetrically installed along the cylinder. The two ends of the cylinder are conical, and the outer surface of the cylinder is in contact with the surface of the grinding belt.

[0015] The system utilizes a suction fan to generate suction, and with the connection of the air pipe, outside air is drawn into the cylinder through the through hole. During the air intake process, the airflow carries the abrasive dust generated by the grinding belt on the surface of the crank neck into the cylinder. With the connection of the air pipe, the air and abrasive dust are discharged by the suction fan into the dust filter, thereby filtering the abrasive dust and reducing its impact.

[0016] Preferably, the through holes are evenly distributed along the circumferential direction of the central axis of the cylinder, and the air tube is a flexible tube.

[0017] This invention provides a machining and grinding device for automotive crankshafts. It has the following beneficial effects: I. This automotive crankshaft machining and grinding device utilizes the movement of the output end of the linear actuator to apply driving force to the connecting slider, which in turn drives the hydraulic cylinder and grinding assembly to move linearly together, adjusting the overall position of the grinding assembly to facilitate grinding of crank journals at different locations.

[0018] II. This automotive crankshaft machining and grinding device utilizes a square guide post that is pushed to a position close to the automotive crankshaft. With the connection of the connecting teeth, the position of the grinding belt can be adjusted. By contracting the output end of the hydraulic cylinder, a reverse pulling force can be applied to the square guide post, causing the grinding belt to move away from the crank neck. When the automotive crankshaft rotates, it is easy to adapt to the eccentric rotation of the crank neck, control the distance between the grinding belt and the crank neck, and facilitate effective grinding.

[0019] 3. This automobile crankshaft machining and polishing device extends between two sets of symmetrical cranks via connecting teeth. After the polishing belt contacts the surface of the crank neck, the polishing belt can become an arc-shaped bend to accommodate crank necks of different diameters. The servo motor is then turned on to operate. The rotation of the output end of the servo motor drives the drive wheel to rotate, and under the rolling support of the driven wheel, the polishing belt rotates, thus polishing the surface of the crank neck.

[0020] IV. This automotive crankshaft machining and grinding device utilizes the rotation of the lead screw at the end of the lead screw pusher to drive the I-shaped block to slide. Under the support of the herringbone frame, the conical centering cap moves linearly, allowing adjustment of the distance between the conical centering cap and the chuck. This adapts to automotive crankshafts of different lengths and supports the end of the automotive crankshaft furthest from the chuck. The central axis of the automotive crankshaft coincides with the axis of the chuck, thereby centering the automotive crankshaft and making its rotation more stable.

[0021] 5. This automotive crankshaft machining and grinding device uses rolling balls in the guide groove to generate rolling friction, which makes the herringbone frame drive the conical centering cap to move smoothly and is less prone to jamming. Furthermore, the anti-slip strips are evenly distributed on the inner side of the conical centering cap, which increases the friction when the end of the automotive crankshaft away from the chuck contacts the anti-slip strips, making it less prone to slippage.

[0022] VI. The automobile crankshaft machining and grinding device supports the cylinder through the support spring. Under the action of the cylinder's own weight, the surface of the cylinder is in contact with the surface of the grinding belt. When the grinding belt is running, the cylinder rolls, which can support the grinding belt and make it less likely to jump. The grinding belt runs stably during grinding.

[0023] 7. In this automobile crankshaft processing and grinding device, when the cylinder is rolling, both ends of the cylinder are connected to the air pipe through a rotating connector, which makes the cylinder run smoothly and is less likely to jam.

[0024] 8. This automotive crankshaft machining and grinding device utilizes a suction fan to generate suction, and with the connection of an air pipe, outside air is blown into the interior of the cylinder through a through hole. During the air intake process, the airflow carries the grinding dust generated by the grinding belt on the surface of the crankshaft journal into the interior of the cylinder. With the connection of the air pipe, the air and grinding dust are discharged by the suction fan into the interior of the dust filter, thereby filtering the grinding dust and reducing its impact.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] For the first embodiment, please refer to... Figure 1-5 The present invention provides a technical solution: An automotive crankshaft machining and grinding device, comprising: The machine body 1, and a rotary driver 2 fixedly installed on the top side of the machine body 1. A chuck 3 is fixedly installed at the output end of the rotary driver 2. A bracket 4 is fixedly installed on the side of the surface of the machine body 1. A support mechanism 5 is installed on the top of the machine body 1 and at the end away from the rotary driver 2. The processing mechanism 6 includes a linear actuator 61 and a connecting slider 62. The linear actuator 61 is fixedly mounted on the top of the bracket 4, and the connecting slider 62 is fixedly mounted on the output end of the linear actuator 61. A frame 63 is fixedly mounted on the side of the surface of the connecting slider 62, and a hydraulic cylinder 64 is mounted on the side of the top of the connecting slider 62. A grinding component 65 is mounted at the center of the frame 63. With the support of the bracket 4 for the linear actuator 61, the operator starts the linear actuator 61 to work. By moving the output end of the linear actuator 61, a driving force can be applied to the connecting slider 62, which can drive the hydraulic cylinder 64 and the grinding component 65 to move linearly together. Adjusting the overall position of the grinding component 65 makes it easier to grind the crank neck at different positions. The linear actuator 61 is mounted parallel to the body 1, and the surface of the connecting slider 62 is in contact with the inner side of the linear actuator 61.

[0029] The grinding assembly 65 includes a square guide post 651 and a connecting tooth 652. The square guide post 651 is slidably mounted at the center of the frame 63. The telescopic end of the hydraulic cylinder 64 is fixedly mounted between the telescopic end and the side of the surface of the square guide post 651. A driven wheel 653 is rolled on the end of the connecting tooth 652 away from the square guide post 651. A support spring 654 is fixedly connected to the middle of the surface of the connecting tooth 652. A driving wheel 655 is rolled on the middle of the interior of the square guide post 651. A grinding belt 656 is installed between the driven wheel 653 and the driving wheel 655. A servo motor 657 is fixedly mounted on the surface of the square guide post 651 near the driving wheel 655. The operator activates the hydraulic cylinder 64 to begin operation. By extending the output end of the hydraulic cylinder 64, a pushing force is applied to the square guide post 651. With the support of the frame 63, the square guide post 651 is pushed towards the position close to the crankshaft. With the connection of the connecting gear 652, the position of the grinding belt 656 can be adjusted. By retracting the output end of the hydraulic cylinder 64, a reverse pulling force is applied to the square guide post 651, causing the grinding belt 656 to move away from the crank neck. When the crankshaft rotates, it is easier to adapt to the eccentric rotation of the crank neck, control the distance between the grinding belt 656 and the crank neck, and perform effective grinding.

[0030] The connecting teeth 652 are installed at an angle. There are two connecting teeth 652, and the two connecting teeth 652 are symmetrically installed along the central axis of the square guide post 651. The two connecting teeth 652 support the grinding belt 656, and the two symmetrical connecting teeth 652 form a V-shaped opening. The connecting teeth 652 extend to the space between two sets of symmetrical cranks. After the grinding belt 656 contacts the surface of the crank neck, the grinding belt 656 can become an arc-shaped bend to adapt to crank necks of different diameters. The servo motor 657 is then turned on to start working. The rotation of the output end of the servo motor 657 drives the drive wheel 655 to rotate. Under the rolling support of the driven wheel 653, the grinding belt 656 rotates to grind the surface of the crank neck.

[0031] The end of the central shaft of the drive wheel 655 is fixedly installed to the output end of the servo motor 657 via a coupling, and the support spring 654 is a wavy curved surface.

[0032] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 6 As shown: The support mechanism 5 includes a rectangular hole 51, a guide groove 52, and a lead screw actuator 53. The rectangular hole 51 is located on the top side of the surface of the machine body 1, and the guide groove 52 is located on the top side of the machine body 1. The lead screw actuator 53 is installed on the surface of the machine body 1 near the rectangular hole 51, and the lead screw of the lead screw actuator 53 extends into the interior of the machine body 1. An I-shaped block 54 is slidably installed on the surface of the machine body 1 through the rectangular hole 51. A herringbone frame 55 is fixedly installed on the surface of the I-shaped block 54. A ball bearing 56 is rotatably installed at the bottom of the herringbone frame 55 near the guide groove 52. A conical centering cap 57 is rotatably installed at the top of the herringbone frame 55, and an anti-slip strip is fixedly connected to the conical surface on the inner side of the conical centering cap 57. 58. Insert one end of the automobile crankshaft that needs to be ground into the jaws on the surface of the chuck 3, and fix one end of the automobile crankshaft by the jaws on the surface of the chuck 3. The operator starts the lead screw pusher 53 to work. By rotating the lead screw at the end of the lead screw pusher 53, the I-shaped block 54 can be driven to slide. With the support of the herringbone bracket 55, the conical centering cap 57 can move linearly. The distance between the conical centering cap 57 and the chuck 3 can be adjusted to accommodate automobile crankshafts of different lengths. It also supports the end of the automobile crankshaft away from the chuck 3. The central axis of the automobile crankshaft coincides with the axis of the chuck 3, thereby centering the automobile crankshaft and making the rotation of the automobile crankshaft more stable.

[0033] The I-shaped block 54 is threadedly installed between itself and the screw surface of the screw pusher 53. There are two I-shaped blocks 54, and the two I-shaped blocks 54 are symmetrically installed along the central axis of the machine body 1.

[0034] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 8 As shown: A dust removal mechanism 7 is installed on the top of the connecting slider 62. The dust removal mechanism 7 includes a dust filter 71. The bottom of the dust filter 71 is fixedly installed on the top of the connecting slider 62 via a Z-shaped base. A support spring 72 is fixedly installed on the side of the surface of the dust filter 71. A cylinder 73 is rotatably installed at the end of the support spring 72 away from the dust filter 71. Rotary connectors 74 are installed at both ends of the surface of the support spring 72. A through hole 75 is opened in the middle of the outer circular surface of the cylinder 73. The middle of the surface of the dust filter 71... A suction fan 76 is fixedly installed at the interval. The air inlet of the suction fan 76 is connected to the end of the rotary connector 74 away from the cylinder 73 by an air pipe 77. The cylinder 73 is supported by the support spring 72. Under the action of the cylinder 73's own weight, the surface of the cylinder 73 is in contact with the surface of the grinding belt 656. When the grinding belt 656 is running, the cylinder 73 rolls, which can support the grinding belt 656, making the grinding belt 656 less prone to jumping and ensuring stable operation of the grinding belt 656 during grinding. The support spring 72 is arc-shaped, and there are two support springs 72, which are symmetrically installed along the cylinder 73. The two ends of the cylinder 73 are conical, and the outer surface of the cylinder 73 is in contact with the surface of the grinding belt 656. When the cylinder 73 is rolling, the two ends of the cylinder 73 are connected to the air pipe 77 through the installation of the rotating connector 74, so that the cylinder 73 runs smoothly and is less likely to get stuck.

[0035] The through holes 75 are evenly distributed along the circumference of the central axis of the cylinder 73. The air pipe 77 is a flexible hose. When the operator turns on the suction fan 76, the suction fan 76 generates suction, and with the connection of the air pipe 77, the outside air is blown into the inside of the cylinder 73 through the through holes 75. During the air intake process, the airflow carries the abrasive dust generated by the grinding belt 656 grinding the surface of the crank neck into the inside of the cylinder 73. With the connection of the air pipe 77, the air and abrasive dust are discharged into the dust filter 71 by the suction fan 76, thereby filtering the abrasive dust and reducing its impact.

[0036] In use, first insert one end of the automobile crankshaft that needs to be ground into the jaws on the surface of the chuck 3, and fix one end of the automobile crankshaft by the jaws on the surface of the chuck 3. Then, the operator starts the lead screw pusher 53. By rotating the lead screw at the end of the lead screw pusher 53, the I-shaped block 54 can be driven to slide. With the support of the herringbone bracket 55, the conical centering cap 57 can move linearly. The distance between the conical centering cap 57 and the chuck 3 can be adjusted to accommodate automobile crankshafts of different lengths. The end of the automobile crankshaft away from the chuck 3 is supported. The central axis of the automobile crankshaft coincides with the axis of the chuck 3, thereby centering the automobile crankshaft. The staff started the rotary driver 2 and used the output end of the rotary driver 2 to drive the chuck 3 to rotate. With the centering support of the conical centering cap 57, the crankshaft of the car rotated more smoothly. At this time, the servo motor 657 is turned on to work. The rotation of the output end of the servo motor 657 can drive the drive wheel 655 to rotate, and under the rolling support of the driven wheel 653, the grinding belt 656 is rotated. At the same time, the operator starts the hydraulic cylinder 64 to work. By extending the output end of the hydraulic cylinder 64, a pushing force can be applied to the square guide post 651. With the support of the frame 63, the square guide post 651 is pushed to move closer to the crankshaft. With the connection of the connecting gear 652, the position of the grinding belt 656 can be adjusted. By retracting the output end of the hydraulic cylinder 64, a reverse pulling force can be applied to the square guide post 651, causing the grinding belt 656 to move away from the crank neck. When the crankshaft rotates, it is easy to adapt to the eccentric rotation of the crank neck, control the distance between the grinding belt 656 and the crank neck, and grind the surface of the crank neck. Furthermore, the cylinder 73 is supported by the support spring 72, and under the action of the cylinder 73's own weight, the surface of the cylinder 73 is in contact with the surface of the grinding belt 656. When the grinding belt 656 is running, the cylinder 73 rolls, which can support the grinding belt 656, making the grinding belt 656 less prone to jumping and ensuring stable operation of the grinding belt 656 during grinding. After the first crank neck is finished being ground, the output end of the hydraulic cylinder 64 can be continuously contracted to separate the grinding belt 656 from the crank neck. The linear actuator 61 is supported by the bracket 4. The operator can start the linear actuator 61 to work. By moving the output end of the linear actuator 61, a driving force can be applied to the connecting slider 62, which can drive the hydraulic cylinder 64 and the grinding assembly 65 to move linearly together. The overall position of the grinding assembly 65 can be adjusted to facilitate the grinding of the crank neck at different positions. Furthermore, the staff turns on the suction fan 76 to operate, using the suction fan 76 to generate suction, and with the connection of the air pipe 77, outside air is blown into the inside of the cylinder 73 through the through hole 75. During the air intake process, the airflow carries the abrasive dust generated by the grinding belt 656 grinding the surface of the crank neck into the inside of the cylinder 73. With the connection of the air pipe 77, the air and abrasive dust are discharged into the dust filter 71 by the suction fan 76, thereby filtering the abrasive dust and reducing its impact.
