Description

Technical Field

[0001] The utility model belongs to the technical field of clamping, and more specifically, particularly relates to an automatic clamping machine for a sprocket box of a micro-tillage machine. Background Art

[0002] The clamping tool refers to a device used to fasten the workpiece during processing, so that the workpiece remains in a relatively correct position, thereby facilitating the processing of the workpiece. The sprocket box of the micro-tiller is a key part of the micro-tiller. The sprocket box needs to be clamped during processing to ensure the stability of the sprocket box during processing.

[0003] Based on the above, the inventors have discovered the following problems: the clamps of some existing sprocket box clamping machines can only clamp sprocket boxes of a single shape. When clamping and processing sprocket boxes of different shapes (the sprocket box body is square, round, or round at both ends with a square in the middle), it is necessary to reinstall the appropriate clamps. This process is time-consuming and labor-intensive, which seriously affects the processing efficiency of the sprocket box.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic clamping machine for a sprocket box of a micro-tillage machine is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an automatic clamping machine for a sprocket box of a micro-tillage machine to solve the problems of the existing sprocket box clamping technology.

[0006] The purpose and effect of the automatic clamping machine for the sprocket box of a micro-tillage machine of the utility model are achieved by the following specific technical means:

[0007] An automatic clamping machine for a sprocket box of a micro-tiller comprises a workbench, conveyor belts are arranged on both sides of the workbench, a plurality of rollers are arranged on the surface of the workbench, two pairs of clamp assemblies are arranged on both sides of the rollers, a mechanical arm is arranged on one side of the clamp assembly, the mechanical arm is installed on the upper end surface of the workbench through a mounting mechanism, and a processing tool is installed on the front end of the mechanical arm through a mounting piece.

[0008] Furthermore, the clamp assembly consists of an electric cylinder and a slider, the upper end surface of the electric cylinder is connected to the bottom end surface of the workbench by bolts, one end of the slider is connected to the output end of the electric cylinder, the other end of the slider is rotatably connected to a ring through a ball bearing, the side wall of the ring is provided with a pair of support arms, and the upper end surfaces of the pair of support arms are rotatably connected to a contact roller through a mounting part.

[0009] Furthermore, the workbench surface is provided with two pairs of rectangular through holes, the inner wall of the rectangular through hole is provided with a slide groove, and the slide groove is slidably connected to the slider.

[0010] Furthermore, a return spring is provided between the bottom end surface of the ring and the top end surface of the slider.

[0011] Furthermore, a rubber pad is provided on the outer wall of the contact surface roller.

[0012] Furthermore, the roller rotates synchronously with the conveyor belt.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the cooperation of the electric cylinder and the slider, the slider can perform reciprocating motion, and the ring is connected to the slider through ball rotation, so that the support arm of the outer wall of the ring can rotate smoothly. When one of the pair of contact rollers at the front end preferentially contacts the outer wall of the sprocket box, the support arm can be rotated to make the first contact roller that preferentially contacts the outer wall of the sprocket box move to a suitable contact point through rotation, and cooperate with the second contact roller to contact the outer wall of the sprocket box. Through the cooperation of the above components, the clamp assembly can clamp sprocket boxes of different shapes, and has eight contact points with the sprocket box, so that the clamping effect is more stable, thereby achieving the purpose of stable clamping of sprocket boxes of different shapes.

[0015] The clamping assembly in the utility model has high adaptability to the specifications and shapes of the sprocket box, and the operator does not need to replace the clamp for the sprocket box with different shapes, which saves time and further improves the working efficiency of the sprocket box processing.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 3 As shown:

[0026] The utility model provides an automatic clamping machine for a sprocket box of a micro-tiller, comprising a workbench 1, conveyor belts 2 are arranged on both sides of the workbench 1, a plurality of rollers 3 are arranged on the surface of the workbench 1, two pairs of clamp assemblies 4 are arranged on both sides of the rollers 3, a mechanical arm 5 is arranged on one side of the clamp assembly 4, the mechanical arm 5 is installed on the upper end surface of the workbench 1 through a mounting mechanism, a processing tool 6 is installed at the front end of the mechanical arm 5 through a mounting piece, the conveyor belts 2 on both sides of the workbench 1 cooperate with the rollers 3, so as to achieve the purpose of transporting the sprocket box, and the clamp assembly 4 cooperates with the processing tool 6 at the front end of the mechanical arm 5, so as to achieve the effect of automatically clamping and installing the sprocket box.

[0027] The clamp assembly 4 is composed of an electric cylinder 401 and a slider 403. The upper end surface of the electric cylinder 401 is connected to the bottom end surface of the workbench 1 through a bolt 402. One end of the slider 403 is connected to the output end of the electric cylinder 401. The other end of the slider 403 is rotatably connected to a ring 404 through a ball 408. The side wall of the ring 404 is provided with a pair of arms 405. The upper end surfaces of the pair of arms 405 are rotatably connected to a contact roller 406 through a mounting member. The slider 403 can reciprocate through the cooperation of the electric cylinder 401 and the slider 403. The ring 404 is rotated by a ball 408. The ball 408 rotates the connecting slider 403, so that the support arm 405 on the outer wall of the ring 404 can rotate smoothly. When one of the pair of contact rollers 406 at the front end preferentially contacts the outer wall of the sprocket box, the support arm 405 can be rotated to make the first contact roller 406 that preferentially contacts the outer wall of the sprocket box be displaced to a suitable contact point through rotation, and cooperate with the second contact roller 406 to contact the outer wall of the sprocket box. Through the cooperation of the above-mentioned components, the clamp assembly 4 can clamp sprocket boxes of different shapes, and has eight contact points with the sprocket box, so that the clamping effect is more stable, thereby achieving the purpose of stably clamping sprocket boxes of different shapes.

[0028] Among them, two pairs of rectangular through holes are provided on the surface of the workbench 1, and a slide groove 409 is provided on the inner wall of the rectangular through hole. The slide groove 409 is slidably connected with the slider 403. Through the cooperation of the slide groove 409 and the slider 403, the piston rod of the electric cylinder 401 does not need to bear weight, thereby improving the service life of the electric cylinder 401.

[0029] A return spring 407 is provided between the bottom end surface of the ring 404 and the top end surface of the slider 403 . After the clamping work is completed, the return spring 407 is used to return the rotated support arm 405 to its original position.

[0030] The outer wall of the contact roller 406 is provided with a rubber pad, which increases the friction with the outer wall of the sprocket box and makes the clamping more stable.

[0031] The roller 3 rotates synchronously with the conveyor belt 2 to transport the sprocket box before and after processing.

[0032] The specific usage and function of this embodiment are as follows:

[0033] Before using this equipment, the staff needs to perform a power-on self-test on the equipment. After the self-test is completed, the staff will place the sprocket boxes to be processed on the conveyor belt 2 on one side of the workbench 1 in turn. After the placement is completed, the staff will start the conveyor belt 2 and the roller 3. When the sprocket box to be processed is transported to the center position of the roller 3 area, the conveyor belt 2 and the roller 3 will stop at the same time. After the staff confirms that the sprocket box to be processed is in the center position of the roller 3 area, the clamp assembly 4 is started to make the piston rod of the electric cylinder 401 push the contact roller 406 toward the direction of the sprocket box to be processed. After the eight contact rollers 406 are in contact with the outer wall of the sprocket box to be processed, the staff will check whether the clamping is firm. After ensuring that it is firm, the operator starts the robot arm 5 to use the front end The processing tool 6 processes the sprocket box to be processed. After the processing is completed, the operator operates the electric cylinder 401 to pull the contact surface roller 406 out of the processed sprocket box through the piston rod. Then, the operator starts the roller 3 and the conveyor belt 2 again to transport the processed sprocket box away. Through the cooperation of multiple clamp assemblies 4, the contact surface roller 406 at the front end can clamp sprocket boxes of different specifications or irregular shapes, and the clamp assembly 4 has more contact points with the sprocket box, which can clamp the sprocket box better and more stably. The clamp assembly has high adaptability to the specifications and shapes of the sprocket box. The operator does not need to replace the clamp for sprocket boxes of different shapes, which saves time and improves the work efficiency of sprocket box processing.
