Embodiment

[0036] Refer to Figures 1-8, A production device for a special-shaped camshaft, including a workbench 1. Above the workbench 1, there is a chuck 2. On one side of the chuck 2 above the workbench 1, there is a grinding wheel 3. The grinding wheel 3 is driven to rotate by a first driving part 4. It further includes: a pressing component 5, arranged on one side of the first driving part 4, used to adaptively apply pressure to the grinding wheel 3 according to the shape of the special-shaped camshaft during grinding; a cleaning component 6, sleeved outside the first driving part 4, one end of which is connected to the pressing component 5, used to clean the dust accumulated on the outer wall of the first driving part 4; a lifting component 7, installed on one side surface of the pressing component 5, used to drive the cleaning component 6 to reciprocate. The pressing component 5 includes: a mounting plate 51, the surface of the output shaft of the first driving part 4 is fixedly connected to the mounting plate 51 through a bearing; a connecting cylinder 52, the connecting cylinder 52 is installed on one side surface of the mounting plate 51, and a piston 54 is slidably connected inside the connecting cylinder 52; a compression spring 53, arranged inside the connecting cylinder 52, one end of which is fixedly connected to the inner wall of the connecting cylinder 52, and the other end is fixedly connected to the piston 54; a moving rod 55, fixed on one side surface of the piston 54, one end of the moving rod 55 penetrates through the connecting cylinder 52 and extends to the outside and is fixed with a T-shaped slider 56; a support plate 58 is fixed on the top surface of the workbench 1, a T-shaped sliding groove 57 is opened on one side surface of the support plate 58, and the T-shaped slider 56 slides in the T-shaped sliding groove 57. The cleaning component 6 includes: an air delivery pipe 61, one end of the air delivery pipe 61 is connected to the connecting cylinder 52; a communicating pipe 62, sleeved in an arc shape outside the first driving part 4, and a plurality of jet nozzles 63 are installed on the surface of the communicating pipe 62 at equal intervals; a dust-proof net 64, installed at the jet orifice of the jet nozzle 63. The lifting component 7 includes: a fixing rod 71, one end of the jet nozzle 63 is connected to the fixing rod 71, and a threaded block 72 is fixed at the end of the fixing rod 71; a lead screw 73, the lead screw 73 is arranged on one side of the mounting plate 51, and both ends of the lead screw 73 are rotatably connected to fixing blocks 74 through bearings, and the fixing blocks 74 are installed on one side surface of the mounting plate 51; a lead screw 73, one end of the lead screw 73 is connected to a driving gear 75, and a rack 76 is engaged with the surface of the driving gear 75, and one end of the rack 76 is fixedly connected to the T-shaped slider 56.

[0037] In the present invention, during the grinding operation of the grinding wheel 3, along with the shape characteristics of the special-shaped camshaft body, when rotating, it squeezes the grinding wheel 3 and the connecting cylinder 52 arranged on one side to move synchronously to the right or horizontally. During the movement, the piston 54 at one end of the moving rod 55 slides inside the connecting cylinder 52, and an extrusion spring 53 is arranged inside the connecting cylinder 52. The elastic rebound of the extrusion spring 53 is used to always squeeze the piston 54. When the connecting cylinder 52 moves to the left, the piston 54 is squeezed by the extrusion spring 53 to reset. One end of the moving rod 55 is connected with a T-shaped slider 56, and the T-shaped slider 56 slides up and down inside the T-shaped chute 57. When the grinding wheel 3 moves down to grind other surfaces of the special-shaped camshaft, the pressing component 5 can move synchronously with the grinding wheel 3 and limit the movement of the grinding wheel 3, improving the stability of the device. Such a design can not only limit the movement of the grinding wheel 3 and the first driving part 4 to ensure the accuracy of the grinding wheel 3 during grinding, but also make the grinding wheel 3 always fit the surface of the special-shaped camshaft by using the elastic extrusion force and apply a certain force to avoid the idling phenomenon of the grinding wheel 3 and improve the grinding effect of the device.

[0038] When the pressing component 5 is operating, the piston 54 reciprocates inside the connecting cylinder 52, squeezing the air inside the connecting cylinder 52, so that the air flow is conveyed out through the air delivery pipe 61 and then discharged into the connecting pipe 62. The connecting pipe 62 is sleeved outside the first driving part 4, and a plurality of air jet heads 63 are installed on the surface of the connecting pipe 62. The air flow is ejected through the air jet heads 63 to blow and clean the surface of the first driving part 4, removing the dust and foreign matters attached to the outer wall surface of the first driving part 4, thereby reducing the occurrence of faults of the first driving part 4, saving the maintenance cost, enabling the grinding wheel 3 at the output end of the first driving part 4 to operate normally and stably, and improving the stability of the device.

[0039] While the pressing component 5 is operating, the driving screw 73 rotates by the movement of the driving gear 75 on the tooth surface of the rack 76. The rotation of the driving screw 73 drives the threaded block 72 to move up and down, and then drives the connecting pipe 62 at the end of the fixed rod 71 to move up and down synchronously. One side surface of the threaded block 72 is attached to the surface of the mounting plate 51, playing a role in limiting the movement of the threaded block 72 without affecting the normal operation of the structure. When the connecting pipe 62 reciprocates up and down, the blowing and cleaning area of the cleaning component 6 is effectively increased, making the cleaning by the cleaning component 6 more comprehensive, further reducing the probability of faults of the first driving part 4. At the same time, under the action of the air flow blowing, it can play an auxiliary role in blowing and cooling to accelerate heat dissipation. Embodiment

The support block 8 and the compression spring 9 are arranged to elastically support and limit the pressing component 5. When the pressing plate 17 moves upward, the elastic rebound of the compression spring 9 drives the pressing component 5 and the grinding wheel 3 to move upward and reset to the initial position. The sliding seat 10 slides left and right on the surface of the sliding rod 11, which also plays a role in limiting the movement of the pressing component 5 and the grinding wheel 3, making the structure more stable. Before grinding, according to the length of the special-shaped camshaft, the third driving part 19 is started to drive the claw 2 to move downward, and with the cooperation of the positioning disk 12, the special-shaped camshaft can be clamped and fixed in a vertical state. The claw 2 can be started and stopped through a driving source such as a motor. During grinding, water is conveyed to the water spray head 15 through the water delivery pipe 16. The water spray head 15 sprays water directly at the grinding area between the grinding wheel 3 and the special-shaped camshaft to cool and reduce its temperature, and at the same time plays a role in dust reduction. The water baffle 13 is arranged to prevent water from splashing everywhere. It should be noted that the second driving part 18, the third driving part 19 and the first driving part 4 can be replaced by driving sources such as motors, cylinders or electric push rods.
