Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinder manufacturing technology, and specifically relates to a quick assembly tool for hydraulic cylinders. Background Technology

[0002] When assembling a hydraulic cylinder, it is difficult to manually insert the piston rod into the cylinder body due to the multiple seals on the piston rod. Therefore, a quick assembly tool for hydraulic cylinders is needed. The quick assembly tool for cylinder body and hydraulic cylinder is a tool specially designed to help quickly position and fix the cylinder body and piston rod during the assembly process of hydraulic cylinders. This tool aims to improve the speed and efficiency of hydraulic cylinder assembly and reduce the time and labor intensity of manual operation.

[0003] Existing hydraulic cylinder quick assembly tools use two clamping plates that approach each other to clamp the cylinder body and piston rod, placing them in a concentric position. Then, the piston rod is driven to move into the cylinder body to achieve rapid assembly of the hydraulic cylinder. However, due to the different shapes of cylinder bodies, corresponding clamping parts need to be replaced in order to clamp and assemble cylinders of different shapes. Since they are fixed with multiple bolts, personnel need to use external tools and considerable force to disassemble and replace them. The whole process is very time-consuming and labor-intensive, extending the preparation time before assembly. It also requires the use of external tools (such as wrenches) to complete disassembly and assembly, increasing the complexity of the operation and dependence on tools. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a quick assembly tool for hydraulic cylinders. This tool can quickly disassemble and replace clamping parts without external tools or considerable force, significantly shortening replacement time, improving replacement efficiency, and reducing the burden on operators.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a hydraulic cylinder quick assembly tool, including an assembly table, two slide rails are provided on the upper right side of the assembly table, the two slide rails are positioned correspondingly, a sliding plate is slidably arranged between the two slide rails, a first slide rail frame is provided on the upper end of the sliding plate, two clamping arc plates are slidably arranged inside the first slide rail frame, a connecting plate is provided on the upper left side of the assembly table, a second slide rail frame is provided on the upper end of the connecting plate, two slide rail frames are also slidably arranged inside the second slide rail frame, rectangular frames are provided on the inner sides of both slide rails, the slide rails and rectangular frames are fixed together by welding, clamping frame plates are slidably arranged inside the two rectangular frames, an assembly drive mechanism is provided on the upper right side of the assembly table, a first drive mechanism for moving the two clamping arc plates is provided inside the first slide rail frame, a second drive mechanism for moving the two clamping frame plates is provided inside the second slide rail frame, a quick-release mechanism for quick assembly and disassembly of the clamping frame plates is provided inside the rectangular frames, and the assembly drive mechanism... The driving mechanism includes an electric push rod located on the right side of the upper part of the assembly table. The telescopic end of the electric push rod is connected to the right side of the sliding plate. The first driving mechanism includes a double-acting screw rod rotatably located inside the first slide frame. Two clamping arc plates are threadedly connected to the corresponding front and rear ends of the double-acting screw rod rotatably. A motor is located on the rear side of the first slide frame. The output shaft of the first motor is connected to the rear end of the double-acting screw rod rotatably via a coupling. The second driving mechanism includes a double-acting screw rod rotatably located inside the second slide frame. Two sliding frames are threadedly connected to the corresponding front and rear ends of the second double-acting screw rod rotatably. A motor is located on the rear side of the second slide frame. The output shaft of the second motor is connected to the rear end of the second double-acting screw rod rotatably via a coupling. The quick-release mechanism includes locking pins slidably located inside two rectangular frames. Locking holes are opened inside the two clamping frame plates. The two locking pins are inserted into the locking holes. Pull plates are provided at the upper ends of the two locking pins. Springs are provided between the pull plates and the rectangular frames. The two springs are respectively sleeved on the outer arc surfaces of the corresponding locking pins.

[0006] As a further improvement of this utility model, a control panel is provided on the front side of the assembly table, and motor one, motor two and electric push rod are all electrically connected to the control panel.

[0007] As a further improvement of this utility model, a support frame is provided at the lower end of the assembly table, and multiple mounting holes are opened inside the support frame, which are located at the four corners of the support frame.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Firstly, by placing the piston rod to be assembled between two clamping arc plates, and then controlling the first motor to run via the control panel, the output shaft drives the first double-acting screw to rotate, thereby causing the clamping arc plates on both sides to move closer together to clamp and fix the piston rod. Next, controlling the second motor to run via the control panel, the output shaft drives the second double-acting screw to rotate, thereby causing the clamping frame plates on both sides to move closer together to clamp and fix the cylinder body. Then, controlling the electric push rod to run via the control panel, the piston rod between the two clamping arc plates moves to the left into the cylinder body under the restriction of the slide rail, which can quickly achieve the rapid assembly of the hydraulic cylinder.

[0010] Secondly, by pulling the pull plates on both sides in sequence, the locking pin is disengaged from the locking hole in the clamping frame plate. At this time, the spring is in a stretched state. Then, the clamping frame plate can be slid out from the inside of the rectangular frame. Subsequently, the clamping part that is compatible with the cylinder body is slid into the inside of the rectangular frame. Then, the pull plate is released. At this time, the spring quickly rebounds and drives the locking pin to insert into the locking hole of the new clamping part. Cylinder bodies of different shapes can be clamped and fixed. The clamping parts can be quickly disassembled and replaced without external tools and great force, which can significantly shorten the replacement time, improve the replacement efficiency, and reduce the burden on the operator.

[0011] Thirdly, the support frame provides stable support for the assembly platform, while the internal mounting holes allow personnel to quickly and easily fix it in the appropriate position, making the hydraulic cylinder assembly more stable.

[0012] Fourth, the control panel allows for quick control of the electrical components on the hydraulic cylinder rapid assembly tool, making it convenient for personnel to use. Attached Figure Description

[0020] like Figure 1 , 2As shown in Figures 1 and 3, a hydraulic cylinder quick assembly tool includes an assembly table 101.

A drive mechanism 1 for moving the two clamping arc-shaped plates 107 is provided inside the slide rail frame 112. A drive mechanism for moving the two clamping frame plates 105 is provided inside the slide rail frame 113. The second structure includes a quick-release mechanism inside the rectangular frame 114 for quick assembly and disassembly of the clamping frame plate 105. The assembly drive mechanism includes an electric push rod 110 located on the upper right side of the assembly table 101. The telescopic end of the electric push rod 110 is connected to the right side of the sliding plate 108. The first drive mechanism includes a bidirectional lead screw 203 rotatably disposed inside the slide frame 112. Two clamping arc-shaped plates 107 are threadedly connected to the corresponding front and rear ends of the bidirectional lead screw 203. The slide frame 112... A motor 201 is provided on the rear side of 12. The output shaft of the motor 201 is connected to the rear end of the double-acting lead screw 203 via a coupling. The second drive mechanism includes a double-acting lead screw 204 rotatably disposed inside the slide frame 113.

A motor 202 is provided on the rear side of the slide frame 113. The output shaft of the motor 202 is connected to the rear end of the double-acting lead screw 204 via a coupling.

[0021] like Figure 3 , 4 As shown, the quick-release mechanism includes locking pins 302 that are slidably disposed inside two rectangular frames 114. Locking holes are provided inside the two clamping frame plates 105. The two locking pins 302 are respectively inserted into the locking holes.

[0024] When it is necessary to clamp and fix cylinders of different shapes, by pulling the pull plates 301 on both sides in sequence, the locking pin 302 is moved out of the locking hole opened on the clamping frame plate 105. At this time, the spring 303 is in a stretched state. Then, the clamping frame plate 105 can be slid out from the inside of the rectangular frame 114. Then, the clamping part that is compatible with the cylinder is slid into the inside of the rectangular frame 114. Then, the pull plate 301 is released. At this time, the spring 303 quickly rebounds and drives the locking pin 302 to be inserted into the locking hole of the new clamping part. Cylinders of different shapes can be clamped and fixed.

[0025] According to another embodiment of the present invention, such as Figure 1 As shown, a support frame 102 is provided at the lower end of the assembly table 101.
