Description

Technical Field

[0001] The present invention relates to the field of oil cylinder tests, and particularly to an oil cylinder piston rod support device for oil cylinder tests. Background Art

[0002] An oil cylinder is also called a hydraulic cylinder. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. Before leaving the factory, the oil cylinder needs to conduct a piston rod telescoping test. When the piston rod of the oil cylinder conducts the telescoping test, in order to ensure the smoothness of the piston rod telescoping, a support device is usually provided at the bottom of the piston rod.

[0003] Traditional support devices usually set moving wheels at the bottom of the support structure for supporting the piston rod. When the piston rod makes a telescoping movement, the support structure reciprocates driven by the moving wheels. However, during the use of the bearing seat connected to the support rotating shaft on the moving wheel, the fluidity of the lubricating oil inside is poor, and the lubrication effect is not good. Moreover, when the lubricating oil in the bearing seat is severely depleted, the friction during the movement of the support structure will increase, thus aggravating the wear between the support structure and the piston rod. Furthermore, when the distance between the two support mechanisms for supporting the oil cylinder needs to be fixed after adjustment, it relies on fasteners such as bolts for fastening, making the adjustment of the distance between the two support mechanisms too troublesome. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies existing in the prior art, and provide an oil cylinder piston rod support device for oil cylinder tests, which can, when the moving seat moves, convey the lubricating oil inside the storage tank to the inside of the bearing seat through an oil delivery mechanism, thereby greatly improving the fluidity of the lubricating oil inside the bearing seat, and further improving the lubrication effect; and through the cooperation of the oil cylinder support mechanism and the plugging mechanism, the oil cylinder support mechanism after distance adjustment no longer relies on fasteners such as bolts for fastening, and the two oil cylinder support mechanisms are more convenient to adjust the distance.

[0005] The purpose of the present invention is completed through the following technical solutions: This kind of oil cylinder piston rod support device for oil cylinder tests includes a base. The base is provided with a first slide rail and a second slide rail. There are two first slide rails which are arranged in parallel. Two oil cylinder support mechanisms are slidably installed on the first slide rails for supporting the oil cylinder body. A plugging plate is provided on the base along the sliding direction of the oil cylinder support mechanism. On one side of each oil cylinder support mechanism close to the plugging plate, a plugging mechanism is provided for selectively plugging the oil cylinder support mechanism into the plugging plate to fix the oil cylinder support mechanism relative to the base;

[0006] There are also two second slide rails, which correspond to the first slide rails one by one and are arranged collinearly behind the corresponding first slide rails. A moving seat is slidably mounted on the second slide rails, and a lifting plate member is movably mounted on the moving seat. A pressing mechanism is installed on the top of the lifting plate member for pressing the piston rod of the oil cylinder body. The piston rod expands and contracts relative to the oil cylinder body, driving the moving seat to slide along the second slide rails. The pressing mechanism adjusts the height relative to the moving seat through the lifting plate member;

[0007] At least one support rotating shaft is provided at the bottom of the moving seat. At least one bearing seat is supported on the support rotating shaft, and the bearing seat is fixed on the moving seat. Both ends of each support rotating shaft are slidably mounted on the second slide rails through rollers;

[0008] A rack is provided on the base along the sliding direction of the moving seat. The oil delivery mechanism fixed on the moving seat includes an oil delivery pump, a transmission shaft, and a driving gear. The driving gear meshes with the rack for connecting and driving the transmission shaft. The transmission shaft is used for connecting and driving the oil delivery pump to work. One end of the oil delivery pump is connected to an oil storage tank fixed on the base through a hose for oil suction, and the other end of the oil delivery pump supplies oil to the bearing seat through a hose. The bearing seat returns to the oil storage tank through a hose to realize the lubricating oil circulation.

[0009] As a further technical solution, the oil cylinder support mechanism includes a sliding support block slidably connected to the first slide rail, a support plate supported on the sliding support block through a support side plate, and an oil cylinder cushion block movably mounted on the support plate. The oil cylinder cushion block adjusts the installation height on the support plate through a height adjustment component, and the oil cylinder cushion block is used for supporting the oil cylinder body.

[0010] As a further technical solution, the height adjustment component includes a support screw threadedly connected to the support plate and an adjustment nut rotatably connected to the support screw; a V-shaped groove is formed on the oil cylinder cushion block for embedding and placing the oil cylinder body.

[0011] As a further technical solution, the plugging mechanism includes a sliding outer shell fixed on the sliding support block and a handle fixed on the support side plate. A grip pressing plate is slidably mounted on the handle through a sliding rod with a spring. The spring applies an elastic force away from the handle to the grip pressing plate in the natural state. One end of a pull rope is connected to the grip pressing plate, and the other end of the pull rope passes through a pulley and is connected to a T-shaped sliding rod. The T-shaped sliding rod penetrates into the sliding outer shell for connecting and driving a sliding block. An insertion rod is arranged at the bottom of the sliding block slidably mounted in the sliding outer shell, and the insertion rod penetrates out of the sliding outer shell for selectively inserting into the positioning holes evenly distributed on the plugging plate. A sliding block spring is arranged between the sliding block and the inner wall of the sliding outer shell for driving the sliding block to reset.

[0012] As a further technical solution, the lifting plate member includes a lifting plate, and the lifting plate is connected to the moving seat in a lifting manner through a lifting screw rod and a rotating nut. Fixed pads are arranged on the lifting plate for placing the piston rod.

[0013] As a further technical solution, a guide post is fixedly installed on the lifting plate, and a guide sleeve is fixedly installed on the moving seat. The guide post is slidably connected in the guide sleeve to guide the lifting movement of the lifting plate.

[0014] As a further technical solution, the pressing mechanism includes a side support plate arranged on one side of the fixed cushion block, a clamping plate arranged on the other side of the fixed cushion block, and a locking plate arranged above the fixed cushion block. One end of the locking plate is hinged to the side support plate, and the other end of the locking plate is snap-connected to the clamping plate. A pressing block is arranged between the locking plate and the fixed cushion block for cooperating with the fixed cushion block to press the piston rod. The pressing block is movably connected to the locking plate through a pressing screw.

[0015] As a further technical solution, a bayonet is opened on the clamping plate, a chute is opened at a position corresponding to the bayonet on the locking plate, and two elastic buckles are slidably installed in the chute. The elastic buckles are used to snap into the bayonet, and each elastic buckle is supported on a partition plate by a spring. The partition plate is fixed in the chute.

[0016] As a further technical solution, V-shaped grooves are opened at corresponding positions of the pressing block and the fixed cushion block for embedding and placing the piston rod.

[0017] As a further technical solution, a driving pulley is fixedly installed on the transmission shaft. The driving pulley drives a driven pulley through a belt connection, and the driven pulley is installed at the input end of the oil transfer pump.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. Through the cooperation of the moving seat and the oil transfer mechanism, during the process of the piston rod extending, the moving seat can be driven to move to the right, and the driving gear will rotate on the upper part of the rack. Then, through the transmission shaft, the driving pulley, and the driven pulley, the input shaft on the oil transfer pump body is driven to rotate, so that a suction force is generated at the suction port of the oil transfer pump body, and the lubricating oil inside the storage tank is transported to the inside of the bearing seat. The lubricated lubricating oil then flows back to the inside of the storage tank through the oil outlet pipe port, the oil outlet pipe fitting, and the return oil hose, greatly improving the fluidity of the lubricating oil inside the bearing seat and the lubrication effect. In this way, the lubricating oil in each bearing seat will not be severely consumed, the friction when the moving seat moves will not be increased, and the wear between the fixed cushion block and the piston rod is reduced;

[0020] 2. Through the cooperation of the oil cylinder support mechanism and the insertion mechanism, after the left - right distance of the oil cylinder support mechanism is adjusted, just loosen the grip lever, then the grip lever moves forward to its original position under the action of the spring, and then the upper end of the pull rope loses the pulling force, so that the sliding block moves downward under the action of the spring outside the T - shaped slide bar, driving the insertion rod to move downward. Then the lower end of the insertion rod is inserted into one of the insertion holes on the connection plate, effectively fixing the sliding support block on the first slide rail. And during the whole fixing process, there is no need to use fasteners such as bolts for fastening, making it more convenient and fast for the two oil cylinder support mechanisms to adjust the distance;

[0021] 3. Through the setting of the pressing mechanism, after the locking plate is closed, the elastic buckle is engaged with the bayonet on the clamping plate to lock the locking plate. Then the rubber pressing block presses on the top of the outer peripheral surface of the piston rod. Further pressing operations can also be carried out by rotating the pressing screw, ensuring that there is no relative movement between the moving seat and the piston rod when the piston rod performs the telescopic test, improving the reliability when the piston rod drives the moving seat to move;

[0022] 4. Through the cooperation of the grip lever and the pull rope, when it is necessary to pull out the insertion rod from the insertion hole on the insertion plate, just manually grip the grip lever towards the handle, then drive the upper end of the pull rope to move backward through the grip lever, and then the lower end of the pull rope drives the T - shaped slide bar, the sliding block and the insertion rod to move upward, so as to pull out the insertion rod from the insertion hole on the insertion plate, improving the convenience of the insertion rod during the pulling - out operation. Moreover, the structure is simple, the practicability is strong, and it can also improve the efficiency of the oil cylinder support mechanism when adjusting the distance.

[0036] Embodiment: As shown in the attached Figures 1 to 11As shown, this cylinder piston rod support device for cylinder testing includes a base 1, a first slide rail 101, a second slide rail 102, a plug-in plate 103, a rack 104, a positioning hole 105, a cylinder support mechanism 2, a sliding support block 201, a support plate 202, a cylinder cushion block 203, a support screw 204, an adjusting nut 205, a handle 206, a support side plate 207, a plug-in mechanism 3, a sliding outer shell 301, a sliding block 302, a T-shaped slide bar 303, a pull rope 304, a grip pressing plate 305, a plug rod 306, a sliding block spring 307, a pulley 308, a bracket 309, a slide bar with a spring 310, a cylinder body 4, a piston rod 401, a moving seat 5, a bearing seat 501, a support rotating shaft 502, an oil inlet pipe port 503, an oil outlet pipe port 504, a roller 505, a lifting plate member 6, a lifting screw 601, a rotating nut 602, a fixed cushion block 603, a lifting plate 604, a pressing mechanism 7, a locking plate 701, a clamping plate 702, a chute 703, an elastic buckle 704, a pressing screw 705, a pressing block 706, a partition plate 707, a side support plate 708, a bayonet 709, an oil transmission mechanism 8, an oil pump 801, a transmission shaft 802, a driving gear 803, an oil inlet pipe fitting 804, an oil outlet pipe fitting 805, a driving belt pulley 806, a belt 807, a driven belt pulley 808, and an oil storage tank 9.

[0037] Refer to the attached Figure 1 , 2 As shown in FIGS. 7 and 8, two first slide rails 101 and two second slide rails 102 are provided on the base 1 along the length direction, and the two first slide rails 101 are parallel to each other. Two cylinder support mechanisms 2 are slidably mounted on the first slide rails 101 to support the cylinder body 4. A plug-in plate 103 is provided on the base 1 (preferably on the outer edge of one of the first slide rails 101) along the sliding direction of the cylinder support mechanism 2. A plug-in mechanism 3 is provided on one side of each cylinder support mechanism 2 close to the plug-in plate 103. After the installation position of the cylinder body 4 and the cylinder support mechanism 2 is determined, the plug-in mechanism 3 is used to plug the cylinder support mechanism 2 into the plug-in plate 103, so that the cylinder support mechanism 2 is fixed relative to the base 1 (the first slide rail 101).

[0038] As Figure 3 shown in FIGS. 9 and 10, there are also two second slide rails 102, corresponding to the first slide rails 101 one by one, and are arranged collinearly behind the corresponding first slide rails 101. A moving seat 5 is slidably mounted on the second slide rails 102. A lifting plate member 6 is liftably mounted on the moving seat 5. A pressing mechanism 7 is mounted on the top of the lifting plate member 6. The pressing mechanism 7 can adjust the height relative to the moving seat 5 through the lifting plate member 6. The pressing mechanism 7 is used to press the piston rod 401 of the cylinder body 4. The piston rod 401 expands and contracts relative to the cylinder body 4, driving the moving seat 5 to slide along the second slide rails 102.

[0039] As Figure 9As shown in the figure, two support rotating shafts 502 are provided at the bottom of the moving seat 5. Two bearing seats 501 are supported on each support rotating shaft 502. The bearing seats 501 are fixed to the bottom of the moving seat 5. Both ends of each support rotating shaft 502 are slidably mounted on the second slide rail 102 through a roller 505. When the piston rod 401 drives the moving seat 5 to slide along the second slide rail 102, the rollers 505 roll along the second slide rail 102 synchronously.

[0040] Refer to the attached Figure 8 , a rack 104 is provided on the base 1 along the sliding direction of the moving seat 5. The oil delivery mechanism 8 is fixed to the moving seat 5. The oil delivery mechanism 8 includes an oil pump 801, a transmission shaft 802, and a driving gear 803. One end of the transmission shaft 802 is supported at the bottom of the moving seat 5 and moves synchronously with the movement of the moving seat 5. The other end of the transmission shaft 802 is fixedly equipped with a driving gear 803. The driving gear 803 meshes with the rack 104 to drive the transmission shaft 802 to rotate. A driving pulley 806 is also sleeved on the transmission shaft 802. The driving pulley 806 drives the driven pulley 808 through a belt 807. The driven pulley 808 is installed at the input end of the oil pump 801, so that the transmission shaft 802 can drive the oil pump 801 to work. As Figure 9 , 10 shown, one end of the oil pump 801 is connected to the oil storage tank 9 fixed on the base 1 through a hose for oil suction. The other end of the oil pump 801 supplies oil to the bearing seat 501 through a hose. The bearing seat 501 returns to the oil storage tank 9 through a hose to realize the lubricating oil circulation. Preferably, an oil inlet port 503 and an oil outlet port 504 are provided on the bearing seat 501. The oil inlet port 503 is connected to the hose through an oil inlet pipe fitting 804 for the lubricating oil to pass through. The oil outlet port 504 is connected to the hose through an oil outlet pipe fitting 805 for the lubricating oil to be discharged. The length of the hose is sufficient to ensure that the oil pump 801 moves with the moving seat 5 to the end of the second slide rail 102 away from the oil storage tank 9.

[0041] As Figure 4 shown, the oil cylinder support mechanism 2 includes a sliding support block 201 slidably connected to the first slide rail 101. Support side plates 207 are fixed on both sides of the sliding support block 201. A support plate 202 is fixed to the support side plates 207. The oil cylinder pad 203 is threadedly connected to the support plate 202 through a support screw 204. An adjusting nut 205 is installed on the support screw 204. The installation height of the oil cylinder pad 203 on the support plate 202 is adjusted through the support screw 204 and the adjusting nut 205. Preferably, a V-shaped groove is provided on the oil cylinder pad 203 to facilitate the embedding and placement of the oil cylinder body 4. An anti-slip rubber pad is provided in the V-shaped groove.

[0042] Refer to the attached Figure 4 , 5, the plugging mechanism 3 includes a sliding outer shell 301 fixedly installed on the sliding support block 201 and a handle 206 fixedly installed on the support side plate 207. A pressing plate 305 is slidably installed on the handle 206 through a slide rod 310 with a spring. One end of a pull rope 304 is connected to the pressing plate 305, and the other end of the pull rope 304 passes through two pulleys 308 and is then connected to the top of a T-shaped slide rod 303. The pulley 308 is rotatably connected to a bracket 309, and the bracket 309 is fixed on the support side plate 207. The lower end of the T-shaped slide rod 303 penetrates into the sliding outer shell 301 and then drives a sliding block 302. The sliding block 302 is slidably installed in the sliding outer shell 301. An insertion rod 306 is provided at the bottom of the sliding block 302, and the lower end of the insertion rod 306 penetrates out of the sliding outer shell 301 and can be selectively inserted into the positioning holes 105 evenly distributed on the plugging plate 103. A sliding block spring 307 is provided between the sliding block 302 and the inner wall of the sliding outer shell 301. The sliding block spring 307 is sleeved on the T-shaped slide rod 303 and can be used to drive the sliding block 302 to reset. Further, the slide rod 310 with a spring applies an elastic force away from the handle 206 to the pressing plate 305 in the natural state, so that the T-shaped slide rod 303 and the sliding block 302 are both in the lowermost position relative to the sliding outer shell 301. At this time, the insertion rod 306 is inserted into the positioning hole 105. When the pressing plate 305 is pressed, the pressing plate 305 slides close to the handle 206, driving the pull rope 304. The pull rope 304 synchronously drives the T-shaped slide rod 303 and the sliding block 302 to move upward. At this time, the insertion rod 306 is pulled out of the positioning hole 105, and the fixed position of the oil cylinder support mechanism 2 on the plugging plate 103 can be adjusted. Preferably, the T-shaped slide rod 303 has a T-shaped head and can be stuck on the upper surface of the sliding outer shell 301, thereby restricting the downward movement stroke of the T-shaped slide rod 303.

[0043] As Figure 6 , 7As shown in the figure, the lifting plate member 6 includes a lifting plate 604. The lifting plate 604 is connected to the moving seat 5 in a liftable manner through a lifting screw rod 601 and a rotating nut 602. A fixed cushion block 603 is arranged on the upper surface of the lifting plate 604 for placing the piston rod 401. A guide post is also fixedly installed on the lower surface of the lifting plate 604, and a guide sleeve is fixedly installed at a position corresponding to the guide post on the moving seat 5. The guide post is slidably connected in the guide sleeve to guide the lifting movement of the lifting plate 604. Further, the pressing mechanism 7 includes a side support plate 708 arranged on one side of the fixed cushion block 603, a clamping plate 702 arranged on the other side of the fixed cushion block 603, and a locking plate 701 arranged above the fixed cushion block 603. One end of the locking plate 701 is hinged to the side support plate 708, and the other end of the locking plate 701 is snap-connected to the clamping plate 702. A pressing block 706 is arranged between the locking plate 701 and the fixed cushion block 603 for cooperating with the fixed cushion block 603 to press the piston rod 401. The pressing block 706 is movably connected to the locking plate 701 through a pressing screw rod 705, and the tightness of the pressing block 706 is adjusted through the pressing screw rod 705.

[0044] The clamping plate 702 is preferably in a "C" shape, and a bayonet 709 is opened at the top of the clamping plate 702. As Figure 11 shown, a chute 703 is opened at a position corresponding to the bayonet 709 on the locking plate 701. Two elastic buckles 704 are slidably installed in the chute 703. Each elastic buckle 704 is supported on a partition plate 707 through a spring. The partition plate 707 is fixed in the chute 703, and the elastic buckles 704 are used to cooperate with each other to be inserted into the bayonet 709. Preferably, V-shaped grooves are opened at positions corresponding to the pressing block 706 and the fixed cushion block 603 for embedding and placing the piston rod 401, and anti-slip rubber pads are arranged in the V-shaped grooves.

[0045] The working process of the present invention:

[0046] When the piston rod 401 on the oil cylinder body 4 needs to be subjected to a telescopic test, first, the distance between the two oil cylinder support mechanisms 2 is adjusted according to the length of the oil cylinder body 4. During the adjustment, the grip plate 305 is manually gripped towards the handle 206, and then the upper end of the pull rope 304 is driven to move backward through the grip rod 305, so that the lower end of the pull rope 304 drives the T-shaped slide bar 303, the sliding block 302, and the insertion rod 306 to move upward, so that the insertion rod 306 is pulled out from the positioning hole 105 inside the plugging plate 103, and then the oil cylinder support mechanism 2 is moved left and right through the handle 206, so that the distance between the two oil cylinder support mechanisms 2 can be quickly adjusted.

[0047] After the distance between the two oil cylinder support mechanisms 2 is adjusted, place the oil cylinder body 4 on the two oil cylinder pads 203, and then control the piston rod 401 on the oil cylinder body 4 to extend to 1 / 4 of the total stroke. At this time, move the moving seat 5 directly below the piston rod 401, and the height of the fixed pad 603 should be lower than the lowest position of the piston rod 401. Then, by rotating the rotating nut 602, the lifting screw rod 601 drives the lifting plate 6 to move upward under the action of the internal thread of the rotating nut 602, driving the fixed pad 603 to move upward, so that the anti-slip rubber pad in the V-shaped notch will contact the bottom of the outer peripheral surface of the piston rod, thereby holding the piston rod 401. Then close the locking plate 701, so that the elastic buckle 704 is engaged with the bayonet 709 on the clamping plate 702, so that the locking plate 701 is locked. At this time, the pressing block 706 will press on the top of the outer peripheral surface of the piston rod 401. Further pressing operations can also be performed by rotating the pressing screw rod 705 to ensure that there is no relative movement between the moving seat 5 and the piston rod 401 during the telescopic test of the piston rod 401.

[0048] During the extension of the piston rod 401, the pressing mechanism 7 and the lifting plate 6 drive the moving seat 5 to move to the right. During the rightward movement of the moving seat 5, the roller 505 on the support rotating shaft 502 will roll on the upper end surface of the second slide rail 102, and the driving gear 803 will rotate on the upper part of the rack 104, and then drive the transmission shaft 802 and the driving pulley 806 to rotate. The driving pulley 806 drives the driven pulley 808 to rotate through the belt 807, so that the input shaft on the oil transfer pump 801 starts to rotate, and a suction force is immediately generated at the suction port of the oil transfer pump 801, so as to suck the lubricating oil inside the storage tank 9 into the oil inlet pipe fitting 804 through the hose. Then the lubricating oil enters the four bearing seats 501 through the four oil inlet ports 503, and the lubricated lubricating oil then flows back to the inside of the storage tank 9 through the four oil outlet ports 504, the oil outlet pipe fitting 805 and the hose, greatly improving the fluidity of the lubricating oil inside the bearing seat 501.

[0049] It can be understood that for those skilled in the art, equivalent substitutions or changes to the technical solutions and inventive concepts of the present invention should fall within the protection scope of the appended claims of the present invention.
