[0023] In related technologies, hydraulic cylinders, as the actuators of hydraulic systems, are in high demand and come in a variety of types. During the assembly of hydraulic cylinders, it is necessary to ensure the assembly accuracy of the piston rod and the cylinder barrel.

[0024] Especially for large-tonnage hydraulic cylinders (cylinder diameter of more than 500 mm and weight of more than 2 tons), without dedicated assembly equipment, it is usually necessary to use a crane with auxiliary equipment such as support fixtures for alignment and assembly. This not only makes the assembly highly dangerous, but also makes it impossible to guarantee the assembly accuracy, which can easily damage the piston rod surface.

[0025] Therefore, this application provides a hydraulic cylinder assembly machine and production line to solve or improve the problems of high risk, low assembly accuracy, and easy damage to the piston rod surface during hydraulic cylinder assembly.

[0026] The following is combined Figures 1 to 8 This describes an embodiment of the present application.

[0027] According to embodiments of this application, in one aspect, a hydraulic cylinder loading machine is provided, such as... Figure 1 As shown, it includes a frame 1, a piston rod press-fit assembly 2, multiple first support assemblies 3, multiple second support assemblies 4, a cylinder positioning assembly 5, a hydraulic system 10, and an electrical control module; the specific scheme is as follows.

[0028] The frame 1 is a frame made of metal profiles (such as angle iron) by welding or bolting. The frame 1 extends along the first direction X. It should be noted that the first direction X generally refers to a direction in the horizontal plane.

[0029] like Figure 1 As shown, the piston rod press-fit assembly 2, multiple first support assemblies 3, multiple second support assemblies 4, and cylinder positioning assembly 5 are all slidably mounted on the frame 1 along the first direction X. That is, the piston rod press-fit assembly 2, multiple first support assemblies 3, multiple second support assemblies 4, and cylinder positioning assembly 5 are arranged in sequence and are all slidably mounted on the frame 1 along the first direction X. Specifically, they can be slidably connected by the cooperation of slide rails and slide grooves or by the cooperation of rollers and slide grooves.

[0030] The piston rod press assembly 2 can be extended and retracted by a hydraulic cylinder connected to the hydraulic system 10.

[0031] like Figure 1 As shown, the piston rod press-fit assembly 2, the first support assembly 3, multiple second support assemblies 4, and the cylinder positioning assembly 5 are all metal parts; the number of the first support assembly 3 is 2 to 6, specifically any one or any two of 2, 3, 4, 5, and 6; the number of the second support assembly 4 is 2 to 6, specifically any one or any two of 2, 3, 4, 5, and 6.

[0032] Among them, such as Figure 2 As shown, the first support assembly 3 is provided with a first support part 31 that moves up and down along the second direction Z. The first support part 31 is used to slide and support the piston rod 8, as shown. Figure 3 As shown, the second support assembly 4 is provided with a second support part 41 that moves up and down along the second direction Z. The second support part 41 is used to support the lever. The second direction Z is perpendicular to the first direction X. Specifically, the third direction Y refers to the height direction of the frame 1.

[0033] It should be explained that the first support part 31 is used to slide and support the piston rod 8, which means that the first support part 31 and the piston rod 8 can slide relative to each other, such as by providing a lubricating surface or rollers, balls, etc. on the surface of the first support part 31.

[0034] Both the first support section 31 and the second support section 41 can be raised or lowered by a telescopic hydraulic cylinder or a lead screw nut driven by a motor.

[0035] like Figure 1 As shown, the hydraulic system 10 is connected to the piston rod press assembly 2 and the cylinder positioning assembly 5. The hydraulic system 10 provides driving hydraulic oil for the piston rod press assembly 2 and the cylinder positioning assembly 5 to reciprocate along the first direction X.

[0036] like Figure 1 As shown, the electrical control module is specifically an electrical control cabinet, which is connected to the hydraulic system 10, multiple first support components 3, and multiple second support components 4.

[0037] In specific usage, such as Figure 1 and Figure 8 As shown, there are two first support components 3 and two second support components 4; the piston rod 8 is hoisted onto the two first support components 3, which are spaced apart; the cylinder 9 is hoisted onto the two second support components 4, which are spaced apart.

[0038] Then, using auxiliary equipment such as a level measuring instrument and a height measuring instrument, the levelness and height of the central axis of the piston rod 8 and the central axis of the cylinder 9 are measured. Then, the electrical control module 11 controls the first support assembly 3 and the second support assembly 4 to raise and lower, so as to make consistent adjustments to the levelness and height of the piston rod 8 and the cylinder 9.

[0039] Then, the hydraulic system 10 is controlled by the electrical control module to make the cylinder positioning assembly 5 make contact with the end of the cylinder 9 away from the piston rod 8, and the piston rod pressing assembly 2 applies pressure to the end of the piston rod 8 away from the cylinder 9 to achieve the pressing of the piston rod 8 and the cylinder 9.

[0040] In this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, multiple first support components 3 and multiple second support components 4 are slidably arranged on the frame 1 along the first direction X. The first support component 3 has a first support part 31 that can be raised and lowered to support the piston rod 8 and adjust its height and level. The second support component 4 has a second support part 41 that can be raised and lowered to support the cylinder 9 and adjust its height and level. This can reduce the overlap error between the central axis of the piston rod 8 and the central axis of the cylinder 9, improve the assembly accuracy, and avoid damage to the surface of the piston rod 8 due to excessive local stress on the surface of the piston rod 8 caused by the low overlap between the central axis of the piston cylinder and the central axis of the cylinder liner.

[0041] Furthermore, by using the cylinder assembly machine described in this application, the piston rod 8 and cylinder liner are supported on the frame 1 during the assembly process, which can reduce the risk of the piston rod 8 and cylinder liner falling off (compared to assembly by overhead crane), thereby reducing danger and improving operational safety.

[0042] In one embodiment, such as Figure 2 As shown, the first support assembly 3 includes a slider support 32, a support wheel plate 311, and two support wheel sets 312. The slider support 32 is slidably connected to the frame 1. Specifically, a guide rail slider is provided at the bottom of the slider support 32, and rollers are provided on the guide rail slide rail to slide and connect with the slide groove on the frame 1.

[0043] The support wheel plate 311 is a metal plate, and the support wheel plate 311 is connected to the slider support 32 through the first lifting component 313. Specifically, the first lifting component 313 is a worm gear lift, which is driven by a servo motor to realize the lifting of the support wheel plate 311. The servo motor is connected to the electrical control module.

[0044] Both support wheel sets 312 are slidably mounted on the support wheel plate 311 along the third direction Y. The third direction Y is perpendicular to both the first direction X and the second direction Z. Specifically, the support wheel set 312 is provided with a slider, and the support wheel plate 311 is provided with a sliding groove along the third direction Y. The slider on the support wheel set 312 slides in cooperation with the sliding groove on the support wheel plate 311. The support sliding groove is provided with multiple positioning holes at intervals along the third direction Y. The slider is provided with a plug hole. The position of the support wheel set 312 is locked by inserting a pin into the positioning hole and the plug hole.

[0045] The axial direction of the support rollers on the support roller assembly 312 is perpendicular to the first direction X and is set at an angle to the third direction Y. The two support roller assemblies 312 are symmetrically arranged so that the two support roller assemblies 312 can form a V shape, which facilitates the support and limit of the piston cylinder and prevents the piston cylinder from rolling. The support roller plate 311 and the two support roller assemblies 312 form the first support part 31.

[0046] Specifically, the support wheel assembly 312 has 2 to 4 support rollers spaced at intervals along the first direction X.

[0047] In this embodiment, such as Figure 2 As shown, the support wheel plate 311 is connected to the slider support 32 through the first lifting assembly 313, which can realize lifting. Two support wheel sets 312 that slide relative to each other along the third direction Y are set on the support wheel plate 311 to support and limit the piston rod 8. The structure is simple and easy to manufacture.

[0048] In one embodiment, such as Figure 3As shown, the second support assembly 4 includes a sliding seat 42 and a support frame 411. The sliding seat 42 is a metal base. The sliding seat 42 and the frame 1 are slidably connected by rollers and sliding grooves on the frame 1. The sliding frame is provided with guide wheels to reduce the lateral friction between the sliding frame and the frame 1.

[0049] The support frame 411 is a metal frame. The support frame 411 is connected to the sliding seat 42 through the second lifting component 413. Specifically, the first lifting component 313 is a worm gear lift, which is driven by a servo motor to realize the lifting of the support frame 411. The servo motor is connected to the electrical control module.

[0050] The support frame 411 is provided with an arc-shaped part 4111. Specifically, the center angle of the arc-shaped part 4111 is 50°~120°, and it can also be other larger or smaller angles, which can be set according to the requirements. The central axis of the arc-shaped part 4111 is parallel to or coincides with the first direction X. Multiple fixing parts 41111 are provided at intervals along the circumference of the arc-shaped part 4111. At least some of the fixing parts 41111 are provided with support rollers 412. The axis of the support rollers 412 is parallel to the first direction X. The support frame 411 is the second support part 41.

[0051] Specifically, the fixing part 41111 is a groove that matches the rotating shaft of the supporting roller 412.

[0052] In this embodiment, such as Figure 3 As shown, the support frame 411 is connected to the sliding seat 42 via the second lifting assembly 413, enabling lifting. An arc-shaped portion 4111 is provided on the support frame 411, and multiple fixing portions 41111 are evenly distributed along the arc direction of the arc portion 4111. At least some of the fixing portions 41111 are optionally equipped with support rollers 412 to support the cylinder 9. The support rollers 412 can be set on the fixing portions 41111 at different positions according to the diameter of the cylinder 9, which can adapt to cylinders 9 of different diameters. The structure is simple and easy to manufacture.

[0053] In one embodiment, such as Figure 3 As shown, the second support component 4 also includes a clamping rope 43. Specifically, the clamping rope 43 can be any flexible rope, such as a clamping chain or steel rope.

[0054] The first end of the clamping rope 43 is connected to the support frame 411 along the third direction Y by a clamping component, and the other end of the clamping rope 43 is connected to the support frame 411 along the third direction Y by a clamping lock. The third direction Y is perpendicular to both the first direction X and the second direction Z.

[0055] Specifically, the clamping rope 43 has a flexible layer, such as a rubber strip, at the part that contacts the cylinder liner.

[0056] In this embodiment, such as Figure 3 As shown, by installing clamping ropes 43 on the support frame 411, the cylinder liner can be locked to prevent it from jumping during assembly and affecting the assembly quality.

[0057] In one embodiment, such as Figure 4 As shown, the piston rod pressing assembly 2 includes a movable frame 21 and a pressure plate 22. The movable frame 21 is a metal frame that is slidably connected to the slide groove on the frame 1 via rollers. The pressure plate 22 is a wear-resistant plate that can improve service life. The pressure plate 22 is slidably mounted on the movable frame 21 along the second direction Z via a sliding block and a slide groove, and is used to press the piston rod 8.

[0058] Specifically, the pressure plate 22 can be locked and adjusted in position with the movable frame 21 via a pin. Specifically, the movable frame 21 is provided with multiple positioning holes along the second direction Z, and the pressure plate 22 is provided with fixing holes. The connection between the pressure plate 22 and the movable frame 21 is realized by inserting a pin into the positioning holes and fixing holes.

[0059] It should be noted that the pressure plate 22 is slidably mounted on the movable frame 21 along the second direction Z. This is to adjust the height of the pressure plate 22. Since the slider is generally made of wear-resistant material and has a certain degree of hardness, its cost is high. The sliding connection between the pressure plate 22 and the movable frame 21 can reduce costs. The pressure plate 22 achieves the pressing of the piston rod 8 by moving the movable frame 21 along the first direction X.

[0060] In this embodiment, such as Figure 4 As shown, by using a pressure plate 22 and a movable frame 21 to slide along the second direction Z, the position of the pressure plate 22 can be adjusted, thereby reducing the volume of the pressure plate 22 and lowering its cost.

[0061] In one embodiment, such as Figure 6 As shown, the cylinder loading machine also includes a clamping assembly 6, which is used to clamp and fix the cylinder 9. The clamping assembly 6 is fixed on the frame 1 by bolts and is located between the first support assembly 3 and the second support assembly 4 that are close to each other. Two first clamping plates 61 are slidably arranged on the clamping assembly 6. The two first clamping plates 61 can move towards each other or away from each other.

[0062] Specifically, the first clamping plate 61 is a metal plate, and the part of the first clamping plate 61 that contacts the cylinder liner is provided with a flexible block, specifically a rubber block, which can prevent scratches on the side of the cylinder liner 9.

[0063] The movable frame 21 is provided with two guide posts and a lead screw extending in the third direction Y. Two first clamping plates 61 are slidably disposed on the two guide posts. The two first clamping plates 61 are threadedly connected to the lead screw. The threads of the parts where the lead screw and the two first clamping plates 61 mate are opposite in direction, that is, one is a left-hand thread and the other is a right-hand thread. The lead screw is driven by a hydraulic motor, which is connected to the hydraulic system 10.

[0064] In actual use, after the cylinder 9 and piston rod 8 are adjusted in level and height, the electrical control module 11 controls the hydraulic system 10 to rotate the hydraulic motor and control the two first clamping plates 61 to move towards each other to clamp the cylinder 9, so as to ensure the stability of the end of the cylinder 9 during the subsequent assembly process.

[0065] In this embodiment, such as Figure 6 As shown, by setting the clamping assembly 6 and clamping the cylinder 9 with the two first clamping plates 61, the stability of the cylinder 9 during the assembly process with the piston rod 8 can be improved, thereby improving the assembly accuracy.

[0066] In one embodiment, such as Figure 7 As shown, the cylinder loading machine also includes a guide sleeve pressing assembly 7. The guide sleeve pressing assembly 7 is slidably mounted on the frame 1 along the first direction X. The guide sleeve pressing assembly 7 is located between the first support assembly 3 and the clamping assembly 6, which are adjacent to the clamping assembly 6. Specifically, the guide sleeve pressing assembly 7 is slidably connected to the slide groove on the frame 1 through rollers.

[0067] The guide sleeve press assembly 7 is driven by a telescopic cylinder connected to a hydraulic supply.

[0068] Two second clamping plates 71 are slidably disposed on the clamping assembly 6, and the two second clamping plates 71 can move towards each other or away from each other.

[0069] Specifically, the guide sleeve press assembly 7 is provided with two guide posts and a lead screw extending in the third direction Y. Two second clamping plates 71 are slidably disposed on the two guide posts. The two second clamping plates 71 are threadedly connected to the lead screw. The threads of the parts where the lead screw and the two second clamping plates 71 mate are opposite in direction, that is, one is a left-hand thread and the other is a right-hand thread. The lead screw is driven by a hydraulic motor, which is connected to the hydraulic system 10.

[0070] In specific use, when installing the guide sleeve 81 on the piston rod 8, the small diameter section of the guide sleeve 81 is clamped by two second clamping plates 71, and the large diameter section of the guide sleeve 81 is limited by the two second clamping plates 71 along the first direction X. Then, the piston rod 8 is pushed by the piston rod press assembly 2 to realize the assembly of the piston cylinder and the guide sleeve 81.

[0071] In one embodiment, such as Figure 5 As shown, the cylinder positioning assembly 5 includes a base 51, an end face blocking plate 52, and two third clamping plates 53. The base 51 is slidably connected to the slide groove on the frame 1 via rollers. The base 51 is provided with positioning pins, which are inserted into multiple position holes spaced apart along the first direction X on the frame 1 to realize the position adjustment of the base 51 and the frame 1.

[0072] The end face baffle 52 is a metal plate. The end face baffle 52 is connected to the base 51 by welding or screwing. The end face baffle 52 is used to limit contact with the end face of the cylinder 9.

[0073] Two third clamping plates 53 are slidably disposed on the base 51 along the third direction Y. The two third clamping plates 53 can move towards each other or away from each other. The third direction Y is perpendicular to both the first direction X and the second direction Z.

[0074] Specifically, the base 51 is provided with a guide post and a lead screw extending in the third direction Y. Two third clamping plates 53 are slidably disposed on the guide post. The two third clamping plates 53 are threadedly connected to the lead screw. The threads of the parts where the lead screw and the two third clamping plates 53 mate are opposite in direction, that is, one is a left-hand thread and the other is a right-hand thread. The lead screw is driven by a manual drive disc.

[0075] In this embodiment, such as Figure 5 As shown, the end face blocking plate 52 is used to limit the end of the cylinder 9, and the cylinder 9 is clamped and fixed by two third clamping plates, which can improve the stability of the cylinder 9 and improve the assembly accuracy.

[0076] In one embodiment, such as Figure 5 As shown, a pressure plate 54 is slidably disposed on one side of the end face baffle plate 52 near the piston rod pressure assembly 2, and a telescopic drive assembly 55 is disposed on the other side of the end face baffle plate 52. Specifically, the telescopic drive assembly 55 is a hydraulic telescopic cylinder, which is connected to the hydraulic system 10.
