Description

Technical Field

[0001] This invention relates to the field of mechanical assembly technology, and in particular to a cylinder block and piston assembly mounting device. Background Technology

[0002] The cylinder is a key actuator in the pneumatic industry; under the action of compressed air, the piston assembly moves within the cylinder body. See also... Figure 1 , Figure 2 As shown, in order to achieve a sealing and sliding effect between the cylinder body 2001 and the piston assembly 1004, two rubber sealing rings need to be installed on the piston assembly 1004 (specifically, the second sealing ring 1003 and the first sealing ring 1001 located on the upper and lower sides of the support ring 1002, with the support ring 1002 located on the outer side of one end of the piston assembly). For the first sealing ring 1001 and the second sealing ring 1003, both sealing rings are larger at one end and smaller at the other. The larger end faces outward (i.e., the larger end of the first sealing ring 1001 faces downward, and the larger end of the second sealing ring 1003 faces upward) and its diameter is larger than the inner diameter of the cylinder body, while the smaller end faces inward and its diameter is smaller than the inner diameter of the cylinder body.

[0003] If the piston assembly 1004 is installed with two sealing rings at its upper end before being installed into the cylinder block 2001, it is a large-diameter installation method of inserting into a small-diameter one. Therefore, the general operating procedure is as follows: First, install one sealing ring (specifically the first sealing ring 1001) on one side of the piston assembly 1004, inserting it from the small end of the sealing ring. Then, install the support ring 1002 and another sealing ring (specifically the second sealing ring 1003) on the other side of the piston. Then, push the cylinder block 2001 back (so that the cylinder block 2001 is forcefully fitted onto the outer side of the upper end of the piston assembly 1004, which has two sealing rings installed), so that the piston assembly and the cylinder block are finally assembled.

[0004] During the above operations, small cylinders are lightweight and can be operated with one hand. However, for larger cylinders with a certain weight, excessive force can easily cause the cylinder body to come off during installation, which may then collide with the piston assembly, cylinder body, and other components, resulting in unnecessary damage to parts and a high error rate. In addition, there is also the problem of high workload for single-person operation.

[0005] Therefore, there is an urgent need to develop a technology that can conveniently, safely, and reliably install the cylinder block and piston assembly together, thereby improving installation efficiency and ensuring installation quality. Summary of the Invention

[0163] It should be noted that the fixed platform 1 includes a fixed pin groove 101, and the fixed pin 301 in the power unit 3 is installed in the fixed pin groove 101 and fixed by the fixed plate 304 in the power unit 3.

[0164] The support rod positioning groove 102 is used to place the support rod 201 and define the position of the support rod 201;

[0165] It should be noted that the bottom positioning circle 702 of the support tube is placed in the support tube fixing hole 106, thereby limiting the position of the support tube 202; the foot pedal limiting groove 107 is used to limit the rotation position of the foot pedal 302 in the power device 3.

[0166] The transmission device placement slot 103 is used to place the transmission block 303 of the power device 3 and the sliding push rod 402 in the transmission device 4. The transmission block 303 and the sliding push rod 402 can slide back and forth laterally in the transmission device placement slot 103.

[0167] In practice, the bracket fixing hole 104 is used to fix the bracket 501 in the lifting device 5 by screws;

[0168] The transmission device limiting groove 105 limits the sliding range of the transmission device 4 (specifically the sliding range of the sliding push rod 402) through the blocking limiting pin 404 in the transmission device 4.

[0169] It should be noted that the fixed platform 1 is a square plate for fixing; the fixed platform serves as the installation base for the entire device; the fixed platform 1 is made of nylon and has grooves and holes of corresponding shapes processed into it for fixing the support device, power device, transmission device, and lifting device, so that the entire device of the present invention is in an upright state. The size of the fixed platform can be designed according to the size of the piston assembly and cylinder body to be assembled as needed.

[0170] It should be noted that the support device 2 includes four support rods 201, which are positioned in four directions by support rod positioning grooves 102, and are connected to the support ring 203 through holes to form a support structure; the bottom of the support tube 202 is placed in the support tube fixing hole 106, which, together with the support ring 203, defines the support tube 202, making the support tube 202 vertically upward; the support ring 203 is connected to the four support rods 201 to define the upper part of the support tube 202;

[0171] In this invention, specifically, the support device 2, the support ring 203 and the support rod 201 are both made of carbon steel and electroplated.

[0172] In practice, the support ring 203 passes through the through hole at one end of the support rod 201 and is fitted onto the upper end of the support tube 202;

[0173] The lower ends of the four support rods 201 are inserted into the support rod positioning slots 102 (specifically, elongated oval slots) at the four corners of the top of the fixed platform 1. The support tubes 202 are kept vertical by gravity and the support of the four support rod positioning slots.

[0174] In practice, the support tube 202 is made of nylon. Its lower end is inserted into the support tube fixing hole 106 in the middle of the fixed platform 1, and its upper end is inserted into the support ring 203 to maintain a vertical position.

[0175] In specific implementation, a support tube guide circle 701 is provided at the upper end of the support tube 202;

[0176] The outer diameter of the guide circle 701 of the support tube is smaller than the outer diameter of the main body of the support tube 202. Therefore, the upper end of the support tube 202 forms a stepped structure.

[0177] It should be noted that the platform between the guide circle 701 (i.e., the small circle) of the support tube and the main body of the support tube 202 (i.e., the large circle) is used to fix the position of the lifting plate 504, and the outer circle of the guide circle 701 (i.e., the small circle) serves as a guide. The support rod 201 and the support tube 202 are designed according to the size variations of the piston assembly and cylinder body, and can be used for different types of cylinder assembly.

[0178] In this invention, specifically, for the power device 3, after the foot pedal 302 is welded to the transmission block 303, it is mounted on the fixing plate 304 using the fixing pin 301.

[0179] In specific implementation, the foot pedal 302, transmission block 303, and fixed pin 301 are all made of carbon steel and electroplated. The two transmission blocks 303 are welded to the foot pedal 302. One end of the fixed pin 301 passes through the through hole on the transmission block 303 and is installed on the fixed plate 304. The fixed pin 301 is fixed on both sides by the fixed plate 304 (the fixed plate 304 is fixed to the fixed platform 1 by screws, limiting the upward movement of the fixed pin 301), so that it can rotate along the axis of the fixed pin 301. After being stepped on by the foot pedal 302, it can provide lifting power for the lifting device 5.

[0180] To better understand the technical solution of the present invention, the working mode of the present invention is described below:

[0181] First, see Figure 12 The piston assembly 1004, with only the first sealing ring 1001 pre-installed at the upper end, is inserted into the support tube 202 from top to bottom;

[0182] Among them, for the piston assembly 1004, the upper part is provided with adjacent, circumferentially distributed second sealing ring mounting groove 10030, support ring mounting groove 10020 and first sealing ring mounting groove from top to bottom;

[0183] Then, see Figure 13 The cylinder body 2001 is installed from top to bottom on the outer side of the upper part of the piston assembly 1004, which only has the first sealing ring 1001 installed, and the lower end of the cylinder body 2001 is in contact with the top surface of the lifting plate 504. At this time, the support ring mounting groove 10020 and the second sealing ring mounting groove 10030 on the upper part of the piston assembly 1004 are exposed (i.e., not covered).

[0184] Then, see Figure 14The support ring 1002 and the second sealing ring 1003 are respectively installed in the support ring mounting groove and the second sealing ring mounting groove on the upper part of the piston assembly 1004. Then, the support ring 1002 is fixed by hand, and the foot pedal 302 is stepped on to make it rotate. This drives the transmission block 303 and the connecting block 401 to rotate in sequence, and at the same time pushes the sliding push rod 402 to move to the right, thereby driving the crank 502 to rotate along the crank pin 505. This pushes the lifting rod 503 upward, and the lifting plate 504 is lifted upward along the guide circle 701 of the support tube, causing the cylinder body 2001 placed on the top of the lifting plate 504 to rise together. See Figure 15 As shown, the support ring 1002 and the second sealing ring 1003 on the piston assembly 1004 are then installed into the cylinder body 2001, thus completing the installation operation of the cylinder body and piston assembly and obtaining the combination of the cylinder body and piston assembly.

[0185] Next, the worker can gently stroke the cylinder body 2001 with their hand and remove their foot from the foot pedal 302. The lifting device 5, transmission device 4, and power device 3 will fall under the action of gravity and stop when the limit stop pin 404 contacts the limit groove of the transmission device. At this time, the cylinder body and piston assembly assembly located at the top of the lifting plate 504 will be removed to complete the assembly operation of a cylinder body and piston assembly assembly.

[0186] It should be noted that, for the present invention, after all cylinders are assembled, the other parts of the fixed platform 1, power unit 3, and transmission device 4, except for the lifting plate 504, can be folded and stored separately, the support tube 202 can be stored separately, and the support rod 201 and support ring 203 can be folded and stored separately.

[0192] 4. In this invention, the power unit is powered by the operator's foot pedal, which relieves the operator of the work of moving the cylinder body by hand, making it easier and faster for the operator to install the cylinder body; it can also provide greater power, making it more convenient and faster to install cylinders with larger weights.
