Description

Technical Field

[0001] This utility model relates to the field of assembly technology, and in particular to an auxiliary device for assembling hydraulic cylinders. Background Technology

[0002] Hydraulic cylinders are the core actuators in hydraulic systems. Their core function is to convert the pressure energy of hydraulic oil into the mechanical energy of linear reciprocating motion, thereby achieving force transmission or displacement control. They are widely used in engineering machinery, machine tools, metallurgical equipment, ships, and other fields. The main structural components include cylinder barrel, piston rod, piston, seals, end caps, guide sleeves, buffer devices, and exhaust devices. The assembly of hydraulic cylinder components requires stable and flat assembly positioning or auxiliary structures, which are necessary conditions for hydraulic cylinder assemblies.

[0003] Chinese patent discloses a hydraulic cylinder assembly device (authorization announcement number CN215617684U). This device includes a worktable fixedly connected to the upper surface of a base plate. Two limiting blocks are fixedly connected to the upper surface of the worktable. A sliding rod is fixedly connected between the opposing sides of the two limiting blocks. A slider is slidably connected to the outer surface of the sliding rod. A fixing plate is fixedly connected to the upper surface of the slider. Two movable blocks are fixedly connected to the upper surface of the fixing plate. A motor is fixedly connected inside the worktable. A rotating rod is fixedly connected to the output end of the motor. A turntable is fixedly connected to the outer surface of the rotating rod. A support is fixedly connected to the upper surface of the worktable. A rotating wheel is movably connected to one end of the support. A synchronous belt is fitted onto the outer surfaces of the rotating wheel and the turntable, preventing the slider from moving arbitrarily. This results in a simple device structure, ease of manufacturing, low footprint, and easy portability.

[0004] This patented technology allows for flexible location determination of the assembly site using a movable cart. However, it has shortcomings. During use, frequent movement to different positions for cylinder assembly causes the ground to be inconsistently level. Furthermore, the pulley structure wears down during use, affecting the level of the assembly equipment and consequently the accuracy of the cylinder assembly, leading to wear and tear on the cylinder structure and ultimately impacting the assembly result. Therefore, those skilled in the art have provided an auxiliary device for cylinder assembly to address the problems mentioned in the background. Utility Model Content

[0038] Bearing seats 19 are provided on both sides of the lower end of the base plate 1. A pulley 20 is rotatably installed inside the bearing seat 19. A guide plate 23 is provided on one side of the lower end of the base plate 1, located on the side of the pulley 20. A brush plate 21 is provided on one side of the guide plate 23. A brush 22 is provided at one end of the brush plate 21, which is equidistantly distributed and attached to the outer wall of the pulley 20. A spring 25 is provided between the brush 22 and the guide plate 23.

[0039] A sliding sleeve 24 is embedded inside the guide plate 23, and a guide rod 26 located inside the spring 25 and slidably inserted into the sliding sleeve 24 is provided at one end of the brush plate 21.

[0040] The upper end of the base plate 1 is provided with symmetrically distributed bearing seats 12, the lower end of the center plate 2 is provided with a connecting plate 13, and the front and rear ends of the connecting plate 13 are provided with mounting shafts 14 that are rotatably installed inside the bearing seats 12. The upper end of the center plate 2 is provided with symmetrically distributed bearing seats 9, and the lower end of the top plate 3 is provided with a connecting plate 11, and the two ends of the connecting plate 11 are provided with mounting shafts 10 that are rotatably installed inside the bearing seats 9.

[0041] A mounting bracket 15 is provided at the upper end of the base plate 1. A bearing seat 3 16 is rotatably mounted inside the mounting bracket 15. A handle 8 is rotatably mounted inside the bearing seat 3 16. A mounting base is provided at the lower end of the handle 8. A wheel frame 17 is provided at the lower end of the mounting base. An adjusting wheel 18 is rotatably mounted inside the wheel frame 17.

[0042] In this embodiment, the device can achieve both "left-right tilt angle adjustment" and "front-back tilt angle adjustment," covering common workshop floor slopes. This ensures that the hydraulic cylinder assembly fixtures on the top plate 3, such as clamps and positioning pins, are always horizontal. Sleeves 5 and 7 are made of 45# steel, which has high strength after tempering. Their internal threads are rolled for high precision, preventing slippage when mating with the screw and ensuring adjustment stability. Screws 30 and 40 are also made of 45# steel with 6g-level external thread precision, ensuring smooth adjustment with an accuracy of ±0.1mm. Levels 27 and 37 correspond to "front-back horizontal" and "left-right horizontal" respectively, allowing operators to observe the bubble position in real time without the need for external testing tools, thus improving adjustment efficiency. Mounting head 1 41 and mounting head 2 42 are provided with rotational support through rotating seat 1 29 and rotating seat 2 39 to adapt to the rotational direction of screw 1 30 and screw 2 40, thus avoiding the influence of the rotational force of screw 1 30 and screw 2 40. The base plate 1, center plate 2, and top plate 3 are made of Q235 low carbon steel, which can be welded and formed to serve as the load-bearing foundation of the equipment, capable of bearing the weight of the tooling during cylinder assembly. Rotating seat 1 29 and rotating seat 2 39 are made of tin bronze, which is self-lubricating and requires no additional oiling, allowing for flexible 360° rotation and preventing jamming during adjustment. Mounting head 1 41 and mounting head 2 42 are made of aluminum alloy 6061 with anodized surface, making them lightweight and easy to adjust. The anodized layer thickness is 10-15μm, which is scratch-resistant and insulating, preventing scratches on the cylinder components to be assembled.

[0043] The horizontal adjustment of the equipment is based on a composite mechanism of "threaded transmission + rotation around the shaft". The equipment moves to the cylinder assembly station via the pulley 20 at the lower end of the base plate 1. At this time, because the ground is not level, the bubble of the level 1 27 is offset. The left and right tilt angles are adjusted. The level 1 27 on the bracket 4 36 is observed. If the bubble is biased to the left, it means that the left side of the equipment is low and the right side is high. The operator rotates the sleeve 2 7. The screw 2 40 inside the sleeve 2 7 extends and retracts to the right under the thread engagement. The screw 2 40 pushes the rotating seat 2 39. The rotating seat 2 39 rotates in the bracket 4 36 through the rotating shaft 4 38, which in turn drives the center plate 2 to rotate clockwise around the mounting shaft 2 14. The adjustment continues until the bubble of the level 1 27 is centered, and the left and right horizontal calibration is completed.

[0044] Support 1 (31) and support 4 (36) are made of high-quality No. 45 carbon steel, heat-treated, and have strong bending resistance. As a supporting frame, they prevent deformation when adjusting the tilt angle and ensure stable force transmission. When adjusting the tilt angle, observe the level 27 on support 1 (31). If the bubble is biased towards the front, it means that the front of the equipment is low and the rear is high. Rotate sleeve 1 (5), screw 1 (30) extends and retracts forward, pushing rotating seat 1 (29) to rotate inside support 1 (31) through rotating shaft 1 (4), causing top plate 3 to rotate counterclockwise around mounting shaft 10 until the bubble on level 27 is centered and the hydraulic cylinder assembly fixture on top plate 3 is completely horizontal, ensuring the accuracy of subsequent cylinder barrel and end cover, piston rod and piston connection. Rotating rod 1 (28) and rotating rod 2 (35) are made of No. 45 steel with knurled surface treatment. The knurled design increases hand friction and prevents slippage in oily environments. Rotating shaft 1 (4) and rotating shaft 4 (38) are made of No. 20 steel with good plasticity, wear resistance and corrosion resistance, reducing wear during rotation and extending service life.

[0045] The pulley 20 is assembled with a polyurethane wheel body and a 20mm high-quality steel chrome-plated axle, which is wear-resistant and shock-absorbing, preventing scratches on the epoxy floor of the workshop. The chrome plating layer of the axle is corrosion-resistant. The guide plate 23 and brush plate 21 are made of Q235 steel, which is thin and lightweight yet has a certain rigidity, weighing only 0.2kg, so it will not increase the burden of equipment movement and can stably support the brush 22 and spring 25. The brush 22 is made of nylon filaments, which are not easy to shed and can clean metal debris and dust from the surface of the pulley 20. The spring 25 is made of 65Mn spring steel, which can provide a continuous pressure of 10-15N to ensure that the brush 22 is always in contact with the pulley 20. When the equipment moves, the 10-15N pressure applied by the spring 25 keeps the brush 22 in contact with the outer wall of the pulley 20. The nylon filaments can sweep off metal debris from the surface of the pulley 20, such as iron filings, dust and oil stains left over from the machining of the cylinder barrel, preventing impurities from getting stuck between the pulley 20 and the ground, which would cause "eccentric wear". The wheel itself has shock absorption properties. The slight wrapping of the brush 22 around the pulley 20 reduces noise during equipment movement. The elastic deformation of the brush 22 allows the pulley 20 to roll over slight bumps in the workshop floor. The brush 22 conforms to the deformation of the pulley 20, preventing cleaning failure due to uneven ground. The 65Mn spring 25 applies continuous elastic pressure to the Q235 steel brush plate 21, ensuring that the nylon brush 22 on the brush plate 21 fits tightly against the outer wall of the PU pulley 20. When the equipment moves through the pulley 20, the pulley 20 rolls around the steel wheel axle, and the brush 22 moves relative to the outer wall of the pulley 20. The nylon bristles sweep impurities, iron filings, and dust from the surface of the pulley 20 to the ground or are subsequently cleaned by the workshop vacuum cleaner. As the brush 22 is used for a long time, the nylon bristles wear down, and the spring 25 automatically extends to maintain the contact pressure between the brush 22 and the pulley 20 until the brush 22 wears down and needs to be replaced, ensuring that the cleaning effect does not diminish over a long period of time.

[0046] The sliding sleeve 24 is made of tin bronze, which has good self-lubricating properties and requires no oiling, preventing oil from entering and affecting sliding. The guide rod 26 is made of 45# steel, ensuring smooth and unobstructed sliding. The guide rod 26 slides linearly within the sliding sleeve 24, restricting the brush plate 21 to move only towards / away from the pulley 20, preventing the brush plate 21 from shifting due to the spring force of the spring 25, and ensuring that the brush 22 is always aligned with the center area of ​​the pulley 20. The guide rod 26 passes through the spring 25, supporting the extension and contraction direction of the spring 25, preventing bending when the spring 25 is compressed / extended, and ensuring that the elastic pressure of the spring 25 is stably transmitted to the brush 22. When the pulley 20 wears or the brush... When the brush plate 21 is subjected to force, it will move with the extension and retraction of the spring 25. At this time, the guide rod 26 slides in a straight line inside the tin bronze sliding sleeve 24, which restricts the movement trajectory of the brush plate 21 and ensures that the brush plate 21 can only move back and forth and will not deviate to the left or right. The guide rod 26 passes through the inside of the spring 25, and the extension and retraction of the spring 25 revolves around the guide rod 26, which prevents the spring 25 from bending due to uneven force and ensures that the pressure of the spring 25 on the brush plate 21 is always perpendicular to the outer wall of the pulley 20. The brush 22 has a uniform contact force, and the self-lubricating property of the sliding sleeve 24 reduces the frictional resistance when the guide rod 26 slides, ensuring that the guiding accuracy is stable for a long time even if the equipment is used for a long time.

[0047] Mounting shaft 10 / 2 is fitted with a bearing housing via deep groove ball bearings. Bearing housing 19 and bearing housing 2 are made of gray cast iron. Connecting plate 11 and connecting plate 213 are made of 45# steel. Mounting shaft 10 and mounting shaft 214 are carburized and quenched. Connecting plate 11 at the lower end of top plate 3 is welded and fixed to mounting shaft 10. Deep groove ball bearings are installed in bearing housing 9 at both ends of mounting shaft 10. When adjusting the front and rear tilt angles, screw 130 pushes bracket 131, which in turn drives top plate 3. Top plate 3 rotates around mounting shaft 10 via connecting plate 11. The deep groove ball bearings reduce rotational friction of the mounting shaft, making rotation smooth. Connecting plate 213 at the lower end of center plate 2 is fitted with mounting shaft 10. Shaft 2 14 is fixed, and the deep groove ball bearing of bearing housing 2 12 is installed in shaft 2 14. When adjusting the left and right tilt angle, screw 2 40 pushes bracket 4 36, which drives the center plate 2 to rotate around shaft 2 14. The gray cast iron material of bearing housing 2 12 absorbs the vibration during rotation and avoids the adjustment accuracy from being affected by impact. The carburized and quenched layers of shaft 1 10 and shaft 2 14 ensure no significant wear after long-term rotation. The bolt connection between the bearing housing and the base plate 1 and the center plate 2 ensures that the position is fixed and the coaxiality accuracy is stable over a long period of time.

[0048] The adjusting wheel 18 is a universal wheel with a built-in brake structure. The handle 8 can rotate 360° through the bearing seat 3 16. The operator can push the adjusting wheel 18 from any direction to adapt to the complex workstation layout of the workshop. For example, if there are other equipment blocking the cylinder assembly table, the operator can grip the aluminum alloy handle 8 with rubber anti-slip sleeve 24. The handle 8 rotates 360° in the gray cast iron bearing seat 3 16 to adjust the pushing direction. If a slight adjustment to the right is needed, turn the handle 8 to the right and apply a pushing force to the handle 8. The pushing force is transmitted to the Q235 steel wheel frame 17 through the 45# steel mounting seat. The wheel frame 17 drives the polyurethane adjusting wheel 18 to roll. The friction between the adjusting wheel 18 and the ground makes the equipment move in the pushing direction. By observing the positioning scale on the equipment or aligning it with the baseline of the cylinder assembly table, the pushing force and angle of the handle 8 can be controlled until the equipment is accurately aligned. After alignment, the handle 8 is released. The adjusting wheel 18 remains stationary due to its own weight, and the equipment position is stable.

[0049] The problem of horizontal deviation caused by frequent movement is addressed by existing equipment which relies on mobile trolleys to flexibly adjust the assembly location. However, it is difficult to maintain a constant level on the workshop floor, and the pulleys 20 are prone to wear during use, causing the assembly equipment to shift, reducing the accuracy of the hydraulic cylinder structure docking, and leading to docking wear. There are also challenges in cleaning the pulleys 20 and fine-tuning the equipment. During movement, the pulleys 20 easily accumulate metal shavings and dust, exacerbating wear and affecting horizontal accuracy. Furthermore, after long-distance movement, the lack of precise alignment methods makes it difficult to quickly align with the assembly station. The equipment utilizes a bidirectional tilt adjustment structure linked to the base plate 1, center plate 2, and top plate 3, combined with real-time monitoring by a level, to achieve left-right and forward-backward tilt adjustment, ensuring the assembly tooling is level, avoiding docking errors, and guaranteeing precise docking of the hydraulic cylinder structure. The pulley 20 self-cleaning mechanism uses a nylon brush 22 pressed by a spring 25 to clean impurities from the pulleys 20 in real time during movement, extending the pulleys 20's lifespan and preventing wear from affecting the level. The overall structure is compatible with multiple specifications of hydraulic cylinders, offering strong adaptability and significantly improving the stability and efficiency of hydraulic cylinder assembly.
