Description

Technical Field

[0001] This utility model relates to the field of hydraulic support column spraying technology, specifically, to an automatic tightening mechanism for the cylinder port plug of a hydraulic cylinder body spraying line. Background Technology

[0002] During the spraying of hydraulic support columns, the existing processing method involves first sealing the cylinder opening of the column with rubber plugs to prevent paint or dust from entering the cylinder. The lifting method involves hooking a hook onto the two lifting rings on the front and rear of the cylinder, keeping the cylinder in a near-horizontal position. This lifting method has the following problems:

[0003] (1) When hoisting horizontally, it is not conducive to the automatic spraying of the reciprocating machine;

[0004] (2) The spacing between the lifting points and the spacing between the lifting rings on the cylinder body are inconsistent, which will make it difficult to lift and adjust the cylinder body to a horizontal state.

[0005] Changing the hoisting method becomes an option, switching from horizontal to vertical hoisting. This requires utilizing the cylinder port thread, installing the cylinder port plug threaded into the cylinder port to achieve a protective function, and installing lifting lugs on the outer end of the cylinder port plug. The cylinder body is then suspended from the cylinder body spraying line through the lifting lugs, achieving vertical hoisting.

[0006] However, due to the different cylinder diameters and the fact that the cylinder plugs are made of iron, manual handling, tightening, and assembly are labor-intensive. Furthermore, when the cylinder diameter is large, the weight of the cylinder plugs is heavy, requiring the assistance of a lifting device, which results in extremely low efficiency. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic tightening mechanism for the cylinder port plug in a hydraulic cylinder body spraying line.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic tightening mechanism for cylinder port plugs in a hydraulic cylinder body spraying line, comprising a pneumatic clamp, a moving seat, a telescopic arm mechanism, a tightening machine, a connecting seat, and a robotic arm;

[0009] The pneumatic clamp is mounted on the front side of the movable seat and is used to clamp the cylinder plug;

[0010] The movable seat is located in front of the connecting seat and mounted on the telescopic arm mechanism. The movable seat can move back and forth under the drive of the telescopic arm mechanism, thereby driving the pneumatic clamp to move back and forth.

[0011] The telescopic arm mechanism is mounted on the connecting seat;

[0012] The tightening machine is installed on the connecting seat and is used to tighten the cylinder plug into the cylinder port of the cylinder body;

[0013] The connector is mounted on the robotic arm;

[0014] The robotic arm can move the pneumatic clamp, the movable seat, the telescopic arm mechanism and the tightening machine together through the connecting seat to realize the transportation of the cylinder plug, so that the cylinder plug can be aligned with the cylinder port and installed into the cylinder port, and when the tightening machine is working, it pushes the tightening machine forward.

[0015] Based on the above, the moving base has a through hole in the middle that matches the outer circle of the tightening machine. The tightening machine passes through the through hole from front to back. The front end of the tightening machine is provided with a bit for tightening the cylinder plug. The rear end of the tightening machine is fixedly installed on the connecting base. Initially, the telescopic arm mechanism is in the extended state, the pneumatic clamp is located in front of the bit, and the pneumatic clamp can hold the cylinder plug.

[0016] When the cylinder plug is aligned with the cylinder body and inserted into the cylinder, the pneumatic clamp releases the cylinder plug, the telescopic arm mechanism retracts backward, and the moving seat drives the pneumatic clamp to move backward to the rear of the bit. The tightening machine can then tighten the cylinder plug into the cylinder body through the bit.

[0017] Based on the above, two sets of pneumatic clamps are symmetrically arranged on the moving base about the left and right sides of the tightening machine.

[0018] Based on the above, the pneumatic gripper is a two-finger parallel pneumatic gripper.

[0019] Based on the above, the telescopic arm mechanism includes two telescopic cylinders parallel to the tightening machine. The two telescopic cylinders are symmetrically arranged about the left and right sides of the tightening machine. The two telescopic cylinders are fixedly installed on the connecting seat, and the front ends of the piston rods of the two telescopic cylinders are connected to the movable seat.

[0020] Based on the above, the upper part of the connecting seat is provided with a flange, and the lower part is provided with two connecting plates spaced apart front to back; the flange is used to connect with the robotic arm; the tightening machine and the two telescopic cylinders are all fixedly connected to the two connecting plates.

[0021] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0022] (1) The integrated design of handling and tightening is realized. The pneumatic gripper and tightening machine are integrated on the robotic arm. The pneumatic gripper can clamp the cylinder plug, and the tightening machine can tighten the cylinder plug into the cylinder. The robotic arm can handle the cylinder plug, thus saving manpower and greatly reducing labor intensity.

[0023] (2) Cost savings. When moving the cylinder blockage, there is no need to use a lifting device for assistance, which saves equipment costs and improves efficiency. Attached Figure Description

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0028] like Figure 1 As shown, an automatic tightening mechanism for cylinder port plugs in a hydraulic cylinder body spraying line includes a pneumatic clamp 1, a movable seat 2, a telescopic arm mechanism, a tightening machine 3, a connecting seat 4, and a robotic arm (not shown).

[0029] The pneumatic clamp 1 is installed on the front side of the movable seat 2 and is used to clamp the cylinder plug 5;

[0030] The movable seat 2 is located in front of the connecting seat 4 and mounted on the telescopic arm mechanism. The movable seat 2 can move back and forth under the drive of the telescopic arm mechanism, thereby driving the pneumatic clamp 1 to move back and forth.

[0031] The telescopic arm mechanism is mounted on the connecting seat 4;

[0032] The tightening machine 3 is installed on the connecting seat 4 and is used to tighten the cylinder plug 5 into the cylinder port of the cylinder body 6.

[0033] The connecting seat 4 is mounted on the robotic arm;

[0034] The robotic arm can drive the pneumatic clamp 1, the movable seat 2, the telescopic arm mechanism and the tightening machine 3 to move together via the connecting seat 4, so as to realize the transportation of the cylinder plug 5, so that the cylinder plug 5 can be aligned with the cylinder port of the cylinder body 6 and installed into the cylinder port, and when the tightening machine 3 is working, it pushes the tightening machine 3 forward.

[0035] In this embodiment, the movable base 2 has a through hole in the middle that matches the outer circle of the tightening machine 3. The tightening machine 3 passes through the through hole from front to back. The front end of the tightening machine 3 is provided with a bit 7 for tightening the cylinder plug 5. The rear end of the tightening machine 3 is fixedly installed on the connecting base 4. Initially, the telescopic arm mechanism is in the extended state, and the pneumatic clamp 1 is located in front of the bit 7. The pneumatic clamp 1 can clamp the cylinder plug 5.

[0036] When the cylinder plug 5 is aligned with the cylinder port of the cylinder body 6 and inserted into the cylinder port, the pneumatic clamp 1 releases the cylinder plug 5, the telescopic arm mechanism retracts backward, and the moving seat 2 drives the pneumatic clamp 1 to move backward to the rear side of the bit 7. The tightening machine 3 can tighten the cylinder plug 5 into the cylinder port of the cylinder body 6 through the bit 7.

[0037] The telescopic arm mechanism allows the pneumatic clamp 1 and the tightening machine 3 to work independently without interfering with each other.

[0038] The pneumatic clamp 1 is arranged in two sets on the movable seat 2 symmetrically about the tightening machine 3.

[0039] The pneumatic gripper 1 is a two-finger parallel pneumatic gripper, which is a conventional technology and can be purchased on the market.

[0040] The telescopic arm mechanism includes two telescopic cylinders 8 parallel to the tightening machine 3. The two telescopic cylinders 8 are symmetrically arranged about the left and right sides of the tightening machine 3. The two telescopic cylinders 8 are fixedly installed on the connecting seat 4. The front end of the piston rod of the two telescopic cylinders 8 is connected to the movable seat 2.

[0041] The upper part of the connecting seat 4 is provided with a flange 41, and the lower part is provided with two connecting plates 42 spaced apart front and back; the flange 41 is used to connect with the robotic arm; the tightening machine 3 and the two telescopic cylinders 8 are all fixedly connected to the two connecting plates 42.

[0042] To facilitate the tightening of the cylinder plug 5 by the tightening machine 3, such as Figure 2 As shown, the lifting lug 9 on the cylinder plug 5 has a square hole 10 coaxial with the cylinder plug 5 in the middle, and the square hole 10 is adapted to the bit 7.

[0043] In this specific embodiment, the movement of the robotic arm aligns the pneumatic clamp 1 with the cylinder port plug 5 and clamps the lifting lug 9 on the cylinder port plug 5, thereby holding the cylinder port plug 5 in place. The robotic arm drives the pneumatic clamp 1 to move, transporting the cylinder port plug 5 to the cylinder port of the cylinder body 6, aligning the cylinder port plug 5 with the cylinder port of the cylinder body 6. The robotic arm pushes the cylinder port plug 5 forward, inserting it into the cylinder port of the cylinder body 6, and aligning the threads of the cylinder port of the cylinder body 6 with the threads on the cylinder port plug 5. Then, the pneumatic clamp 1 releases the lifting lug 9 on the cylinder port plug 5, and the piston rods of the two telescopic cylinders 8 retract synchronously, causing the moving seat 2 to pull the pneumatic clamp 1 backward. To avoid creating rotational space when tightening the cylinder plug 5, the robotic arm moves forward, pushing the tightening machine 3 forward so that the bit 7 at the front end of the tightening machine 3 enters the square hole 10 in the middle of the lifting lug 9 on the cylinder plug 5. Once the piston rods of the two telescopic cylinders 8 are fully retracted, the pneumatic clamp 1 moves away from the lifting lug 9 on the cylinder plug 5 and to the rear of the bit 7. Then, the tightening machine 3 is activated, tightening the cylinder plug 5 into the cylinder port of the cylinder body 6. Under the set torque, the tightening machine 3 ensures the threads of the cylinder plug 5 are tightened. While tightening the cylinder plug 5, the tightening machine 3 can move forward under the push of the robotic arm. After tightening the cylinder plug 5, the robotic arm retracts, causing the tightening machine 3 to exit, preparing for the next cycle.

[0044] This embodiment integrates the functions of handling and tightening into one unit. During use, unmanned operation saves manpower and significantly reduces labor intensity. When handling the cylinder blockage, no lifting device is needed, saving equipment costs and improving efficiency.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
