[0002] Rubber wheels (such as rubber wheels and polyurethane wheels) are widely used in industrial equipment, transportation vehicles, and various types of machinery. During the manufacturing process of rubber wheels, it is usually necessary to machine their outer diameter, end face, or curved surface to achieve the dimensional accuracy and surface finish required by the design.

[0003] Existing rubber wheel processing equipment typically uses two spindles to clamp the rubber wheel for turning by a turning mechanism. To improve the efficiency of a single machine, two more spindles are installed to form two processing stations.

For example, they can refer to a fixed connection, a detachable connection, or an integral part. They can be mechanical or electrical connections. They can be direct connections or indirect connections through an intermediate medium, and can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] like Figures 1 to 4 As shown, this embodiment of the invention provides a rubber wheel turning machine for machining the outer diameter of rubber wheels, such as rubber wheels and polyurethane wheels. The machine includes a first spindle 100, two second spindles 200, a turning mechanism 300, a drive mechanism 400, a feeding mechanism 500, and a loading mechanism 600. The turning mechanism 300 and the drive mechanism 400 are spaced apart on a machine base 800. The first spindle 100 and the two second spindles 200 are all mounted between the turning mechanism 300 and the drive mechanism 400. A loading mechanism 600 is mounted on the upper end of each of the two second spindles 200. The two feeding mechanisms 500 are arranged opposite each other on the upper end of the first spindle 100.

[0030] The first spindle 100 is horizontally positioned, and a first rotating shaft 110 is installed inside it. The first rotating shaft 110 can rotate around its own axis under drive. Both ends of the first rotating shaft 110 extend from the ends of the first spindle 100 and are fixedly mounted with chucks 120. The end of the chuck 120 is provided with a protrusion 121 extending outward along the axial direction. The diameter of the protrusion 121 is slightly smaller than the center hole diameter of the rubber wheel to be processed, so that the rubber wheel can be easily fitted onto the protrusion 121.

[0031] Two second spindles 200 are fixedly installed on the left and right sides of the first spindle 100, respectively, and are coaxial with the first spindle 100. A discharge port 810 is provided at the upper end of the machine base 800, and the discharge port 810 is located between the second spindles 200 and the first spindle 100. Each second spindle 200 is provided with a second rotating shaft 210, which is coaxial with the first rotating shaft 110.

[0032] A push rod 220 is axially inserted inside the second rotating shaft 210, with both ends of the push rod 220 protruding from the second rotating shaft 210. A connecting groove 221 is formed at the end of the push rod 220 facing the first rotating shaft 110, which is adapted to the protrusion 121 on the chuck 120. During operation, the first rotating shaft 110 and the second rotating shaft 210 rotate synchronously, and the second rotating shaft 210 can drive the push rod 220 to rotate synchronously. A fifth cylinder 700 is provided at the end of the first main shaft 100 away from the second main shaft 200. The fifth cylinder 700 is used to drive the push rod 220 to extend and retract along its own axial direction. It should be noted that the cylinder rod of the fifth cylinder 700 is rotatably connected to the push rod 220. Specifically, the outer side of the push rod 220 will be provided with multiple movable grooves along its circumference, and the second rotating shaft 210 will be provided with limiting strips that are adapted to the movable grooves, so that the push rod 220 can be pulled on the second rotating shaft 210 and rotate with the second rotating shaft 210. Furthermore, when the push rod 220 extends towards the first main shaft 100, the protrusion 121 extends into the connecting groove 221 and presses the rubber wheel pre-fitted on the protrusion 121 against the end face of the chuck 120 for subsequent processing.

[0033] This rubber wheel machine can form two processing stations by using a first main shaft 100 and two second main shafts 200. That is, a processing station is formed between a second rotating shaft 210 and the corresponding chuck 120. This can reduce the use of main shafts, save installation space and cost, and make the structure simpler and more compact. It can also ensure that the two processing stations can process synchronously, ensuring processing accuracy and efficiency.

[0034] Furthermore, the drive mechanism 400 is used to drive the first rotating shaft 110 and the second rotating shaft 210 to rotate synchronously. Specifically, as shown in the figure... Figure 2 As shown, the drive mechanism 400 includes a second motor 410 and a drive shaft 420. The drive shaft 420 is arranged axially along the first main shaft 100 and located on the rear side of the first main shaft 100, i.e., the side away from the operator. The drive shaft 420 is connected to the first rotating shaft 110 and two second rotating shafts 210 via pulleys and belts. The second motor 410 is connected to the drive shaft 420 via pulleys and belts. When the second motor 410 is started, the drive shaft 420 rotates, thereby driving the first rotating shaft 110 and the two second rotating shafts 210 to achieve precise synchronous rotation.

[0035] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, the turning mechanism 300 is located on the front side of the first spindle 100, i.e., the side closer to the operator, and is used to turn the clamped rubber wheels. Specifically, the turning mechanism 300 includes a first motor 310, a lead screw 320, a mounting plate 330, a fixing plate 340, and two cutting tools 350. The lead screw 320 is rotatably mounted on the fixing plate 340 via a bearing seat, and its axis is perpendicular to the axis of the first rotating shaft 110 in the horizontal plane. A nut seat 360 is fitted onto the lead screw 320, and the mounting plate 330 is fixed to the nut seat 360. The two cutting tools 350 are respectively mounted on the upper end of the mounting plate 330, and their positions correspond to the rubber wheels on the two chucks 120. To improve the smoothness of movement, a first guide rail 370 is provided at the lower end of the mounting plate 330, and a first slider 380 that slides with the first guide rail 370 is fixed on the fixing plate 340. During operation, the first motor 310 drives the lead screw 320 to rotate, which in turn drives the mounting plate 330 to move axially along the lead screw 320 via the nut seat 360. This allows the two cutters 350 to simultaneously approach and cut the two rubber wheels. The first guide rail 370, mounted on the lower end of the mounting plate 330, prevents fine debris from falling and accumulating on the first guide rail 370, thus affecting the movement of the first slider 380, and also facilitates cleaning.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, the pushing mechanism 500 is used to push the rubber wheel out of the protrusion 121 after processing, causing the rubber wheel to detach from the protrusion 121 and fall into the discharge port 810. Specifically, the pushing mechanism 500 includes a first cylinder 510 and a pushing plate 520. The first cylinder 510 is fixedly installed on the upper end of the first spindle 100, and its axial direction, i.e., the extension and retraction direction of the piston rod, is parallel to the axial direction of the first spindle 100. The pushing plate 520 is a vertically arranged plate body, which is fixedly connected to the end of the piston rod of the first cylinder 510. The pushing plate 520 has a through hole 521, the position and size of which match the chuck 120, so that the chuck 120 can pass through the through hole 521. After the processing is completed and the push rod 220 retracts, the first cylinder 510 extends and pushes the pusher plate 520 to move in the extension direction of the protrusion 121, pushing the end face of the rubber wheel and pushing it away from the protrusion 121. It should be noted that the outer diameter of the rubber wheel is larger than the diameter of the chuck 120.

[0037] Furthermore, such as Figure 1 , Figure 4 and Figure 6As shown, the feeding mechanism 600 is used to grip the rubber wheel to be processed from the feeding position and place it between the protrusion 121 and the push rod 220, and is coaxial with the protrusion 121 and the push rod 220. Specifically, the feeding mechanism 600 includes a connecting plate 610, a second cylinder 620, a third cylinder 630, a fourth cylinder 640, and a thumb cylinder 650. The connecting plate 610 is fixedly installed on the upper end of the second main shaft 200. A second guide rail 660 is provided on the connecting plate 610 along the axial direction of the second main shaft 200. A second slider 670 is slidably provided on the second guide rail 660, and a first fixed seat 680 is fixed on the second slider 670. The second cylinder 620 is arranged along the direction of the second guide rail 660, and its piston rod is connected to the first fixed seat 680. It is used to drive the output end of the feeding mechanism 600 to move horizontally to feed the rubber wheel, that is, to put the rubber wheel on the protrusion 121.

[0038] Furthermore, a third guide rail 690 is provided on the first fixed base 680. The third guide rail 690 is arranged vertically and inclined towards the front of the first main shaft 100. A third slider 691 is slidably arranged on the third guide rail 690, and a second fixed base 692 is fixed on the third slider 691. A third cylinder 630 is located at the upper end of the third guide rail 690, and its piston rod is connected to the second fixed base 692, used to drive the output end of the feeding mechanism 600 to move up and down along the inclined third guide rail 690.

[0039] Furthermore, a fourth slider 693 is fixedly mounted on the second fixed base 692, and the extending direction of the fourth slider 693 intersects the inclined direction of the third guide rail 690 in space. A fourth guide rail 694 is slidably fitted onto the fourth slider 693. A fourth cylinder 640 is mounted on the second fixed base 692, and its piston rod is connected to the fourth guide rail 694, used to drive the fourth guide rail 694 to move along the direction of the fourth slider 693. A thumb cylinder 650 is mounted on the lower end of the fourth guide rail 694, and the thumb cylinder 650 is perpendicular to the fourth guide rail 694. Two grippers on the thumb cylinder 650 are used to grip the rubber wheel.

[0040] During operation, the linkage of the second cylinder 620, the third cylinder 630 and the fourth cylinder 640 enables the thumb cylinder 650 to move to the feeding position to grab the rubber wheel, and then move between the chuck 120 and the push rod 220, so that the rubber wheel is coaxial with the protrusion 121 and the push rod 220. After the rubber wheel is put into the protrusion 121, the thumb cylinder 650 releases and retracts.

[0041] It should be noted that a vibratory feeder is installed at the feeding position, and the vibratory feeder has a conveyor that slopes downwards towards the front of the machine base 800. The conveyor is parallel to the fourth guide rail 694 and has a discharge port. Two hinges spaced apart along the width direction are installed at the discharge port. A rubber wheel located at the discharge port 810 abuts against the hinges. When the hinges are pushed by a certain external force, they can rotate outwards. Specifically, when the gripper on the thumb cylinder 650 clamps the rubber wheel, the fourth cylinder 640 pushes the fourth guide rail 694 to move the thumb cylinder 650 towards the discharge direction of the discharge port. That is, the slope of the fourth guide rail 694 moves downwards, causing the rubber wheel to push the hinges to rotate outwards, so that the rubber wheel can be removed from the discharge port. The gripper on the thumb cylinder 650 can pass between the two hinges.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
