Description

Technical Field

[0001] The utility model relates to the technical field of blanking of handwheel assembly machines, in particular to a blanking mechanism of a handwheel assembly machine. Background Art

[0002] A handwheel assembly machine is an automated device for assembling handwheels. Handwheels are usually used in mechanical operations, such as adjusting the position or speed of equipment. Usually, when the handwheel assembly machine is running, a robotic arm is used to place the unprocessed handwheel into the slot in the handwheel assembly machine, and the robotic arm is also used to take out the assembled handwheel from the handwheel assembly machine.

[0003] For example, an automatic loading and unloading robotic arm, with the publication number: CN220093929U. When a user uses this robotic arm, the robotic arm is placed on the ground or other equipment for fixation. The PLC programmable controller controls the fourth stepping motor to drive the turntable to rotate, and then drives the robotic arm to adjust its orientation. The third stepping motor drives the fixed ring to rotate and then adjusts the angle of the support rod. Then, the user turns on the second stepping motor through the PLC programmable controller, so that the second stepping motor drives the connecting block to rotate, and then adjusts the angle of the connecting rod. The robotic arm can accurately align with the material to be picked up through the infrared sensor. When the alignment is completed, the PLC programmable controller will control the two electric cylinders to drive the output shafts to push the clamping plates, and use the rubber pads to clamp the item. Finally, the item is loaded through the second stepping motor, the third stepping motor and the fourth stepping motor, or the item can be taken out for blanking.

[0004] However, during the blanking process using the robotic arm, it will occupy the time for loading. Therefore, when using the robotic arm to achieve loading and blanking, after the handwheel is assembled, there will be a period of time required for the robotic arm to perform blanking and then loading, so the efficiency of handwheel assembly will be affected. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a blanking mechanism of a handwheel assembly machine.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A blanking mechanism of a handwheel assembly machine, including an operating table for installation inside the handwheel assembly machine.

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] likeFigures 1-4 As shown in the figure, a blanking mechanism of a handwheel assembly machine includes an operating table 2 installed inside the handwheel assembly machine. During actual use, the operating table 2 is replaced and installed at the handwheel placement position of the handwheel assembly machine. One side of the tabletop of the operating table 2 is hinged with a workpiece table 3 for placing the handwheel, and an electric telescopic rod 9 is embedded in the tabletop of the operating table 2. During use, the handwheel is placed on the workpiece table 3 by a robotic arm and clamped and fixed. The telescopic end of the electric telescopic rod 9 is rotatably connected to an inclined plate 4 that is rotatably connected to one side of the workpiece table 3 away from the hinge. After the handwheel assembly is completed, the clamping state of the handwheel is released, and the electric telescopic rod 9 contracts. Under the pushing action of the inclined plate 4, the workpiece table 3 swings upward to an inclined state, so that the handwheel in the released clamping state can slide off. To facilitate guiding the sliding handwheel: A cloth bag 1 is provided on one side of the bottom of the operating table 2 at the hinge of the workpiece table 3. Two bag mouth strips 8 are connected to the mouth of the cloth bag 1. The bag mouth strip 8 away from the hinge of the workpiece table 3 is fixed to the bottom of the operating table 2. The bag mouth strip 8 close to the hinge of the workpiece table 3 is slidably installed on the bottom of the operating table 2 and fixedly connected to a connecting frame 7 inserted into the bottom of the operating table 2. The bottom of the operating table 2 is fixedly connected with an electric push rod 6 for driving the sliding of the connecting frame 7. The connecting frame 7 is U-shaped, and the inner wall of the connecting frame 7 is slidably connected to both sides of the bag mouth strip 8 fixed to the bottom of the operating table 2. Before the workpiece table 3 inclines, the electric push rod 6 extends to drive the connecting frame 7 to push the connected bag mouth strip 8 to move. In this solution, the mouth of the cloth bag 1 used is made of an elastic material. Therefore, when one of the bag mouth strips 8 moves to be misaligned with the operating table 2 as the connecting frame 7 moves, the mouth of the cloth bag 1 can be opened. Therefore, when the workpiece table 3 inclines subsequently, the sliding workpiece will fall into the mouth of the cloth bag 1 and slide along the inner wall of the cloth bag 1. Under the action of the friction force on the inner wall of the cloth bag 1, it can slide down smoothly and fall to the corresponding position.

[0024] In addition: Sliding seats 15 are slidably connected to both sides of the tabletop of the workpiece table 3. Two mounting seats 18 are arranged on the upper surface of the sliding seat 15 from top to bottom. Two sliders 19 are symmetrically and slidably connected inside the mounting seat 18. On both sides of the mounting seat 18 on the side away from the central axis of the operating table 2, winding drums 16 are rotatably connected. A connecting strip 10 passing through the mounting seat 18 is wound around the winding drum 16. A chain 5 is fixedly connected between the two connecting strips 10 on the mounting seat 18. An electric telescopic rod 9 is also fixedly installed on one side of the slider 19. The telescopic end of the electric telescopic rod 9 on the slider 19 is fixedly connected to a connecting frame 17 sleeved on the chain 5. By extending the electric telescopic rod 9 on the slider 19, the connecting frame 17 can be moved to both sides of the handwheel, and the part of the chain 5 between the two connecting frames 17 can be used to fit and clamp the side of the handwheel. In addition, in this solution, a rubber pad can be installed on the chain 5 to increase the friction force and prevent the chain 5 from directly contacting the surface of the handwheel, causing scratches on the surface of the handwheel. According to the size of the handwheel, the connecting strip 10 can be released by rotating the winding drum 16, thereby realizing the adjustment of the length of the chain 5 between the two connecting frames 17.

[0025] The bottom edge of the sliding seat 15 is inserted and embedded in the upper surface of the workpiece table 3, and the electric telescopic rod 9 is also fixedly connected and embedded at the position corresponding to the sliding seat 15 on the upper surface of the workpiece table 3. The electric telescopic rod 9 on the sliding seat 15 is used to drive the sliding seat 15 to slide. By extending and retracting the electric telescopic rod 9 on the workpiece table 3, the position of the sliding seat 15 can be adjusted, that is, to adapt to handwheels of different sizes.

[0026] The lower mounting seat 18 is fixed on the sliding seat 15 and is inserted into the upper mounting seat 18. A long bolt 14 is threaded through the top edge of the upper mounting seat 18 and is rotatably connected to the top edge of the lower mounting seat 18. By rotating the long bolt 14, the distance between the two mounting seats 18 on the sliding seat 15 can be adjusted, so that the two mounting seats 18 on the sliding seat 15 can receive wheels at different heights.

[0027] A bidirectional screw rod 20 with both ends threaded through the two sliders 19 is rotatably connected inside the mounting seat 18. A worm gear 11 is fixedly connected to the top edge of the winding drum 16. A worm 12 meshing with the worm gear 11 is rotatably connected to the top edge of the mounting seat 18. Two motors 13 for driving the bidirectional screw rod 20 and the two worms 12 to rotate respectively are fixedly connected to the mounting seat 18. By driving the bidirectional screw rod 20 to rotate by the motor 13, the distance between the two sliders 19 can be adjusted, and then the distance between the two connecting frames 17 on the mounting seat 18 can be adjusted, so that the mounting seat 18 can clamp handwheels with different arcs. In addition, the motor 13 driving the worm 12 to rotate is a double-shaft motor. Therefore, the double-shaft motor can be used to drive the two worms 12 on the mounting seat 18 to rotate simultaneously, and then the corresponding worm gears 11 drive the winding drums 16 to rotate, realizing the release or winding of the connecting strip 10.

[0028] Working principle: The robotic arm places the handwheel on the workpiece table 3, and adjusts the distance between the two mounting seats 18 on the sliding seat 15, the distance between the two sliders 19 on the mounting seat 18, and the telescopic length of the electric telescopic rod 9 on the slider 19 according to the height and surface curvature of the handwheel. When the electric telescopic rod 9 on the workpiece table 3 contracts, the two sliding seats 15 move closer to each other until the two chains 5 on the sliding seat 15 clamp the side of the handwheel. After the handwheel assembly is completed, the sliding seat 15 resets. When the electric push rod 6 extends, the connecting frame 7 is pushed to move the connected bag mouth strip 8 to be misaligned with the operating table 2, so that the mouth of the cloth bag 1 can be opened. Then, the electric telescopic rod 9 on the workpiece table 3 contracts, and under the pushing action of the inclined plate 4, the workpiece table 3 swings upward to an inclined state, so that the unclamped handwheel can slide and fall into the mouth of the cloth bag 1, and slide along the inner wall of the cloth bag 1. Under the action of the friction force on the inner wall of the cloth bag 1, it can smoothly descend and slide to the corresponding position.

[0029] The wiring diagrams of the electric telescopic rod 9, the electric push rod 6 and the motor 13 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the electric telescopic rod 9, the electric push rod 6 and the motor 13 will not be explained in detail.

[0030] The above is only the preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
