[0018] Beneficial effects of the present invention:

[0019] 1. The present invention facilitates the replacement of multiple cylinders by rotating a cross plate, so as to facilitate continuous assembly between the multiple cylinders and the hydraulic rod, thereby improving the work efficiency during hydraulic cylinder assembly and facilitating mass production. The electric slider is opened to drive the lifting frame to move downward. When the lifting frame moves downward, the hydraulic rod and the cylinder can be docked and installed. The multiple abutment plates can be provided to tighten the rubber ring. The spray head can be provided to evenly spray hydraulic oil on the inner wall of the tightened and expanded rubber ring so that the rubber ring can be installed on the outside of the hydraulic rod after the oiling operation is completed. The air transmission pipe can increase the air pressure in the storage tank when the cross plate rotates. When the air pressure in the storage tank increases, the hydraulic oil in the storage tank is transmitted to the spray head through the transmission pipe and finally sprayed onto the inner wall of the rubber ring by the spray head. After the rubber ring is sprayed with oil, it is manually pushed down to accurately install the rubber ring on the hydraulic rod. Then, the rotation of the transposition plate allows the hydraulic rod and the cylinder to be docked and assembled after the rubber ring is assembled.

[0020] 2. The present invention manually places the bottom of the hydraulic rod into the middle of the fixed cylinder, and then controls the electric slider to open and drive the regulating ring to rotate. When the regulating ring rotates, it drives multiple pushing plates to rotate. When the pushing plates rotate, it drives multiple moving rods to slide on the fixed cylinder. When the multiple moving rods move close to each other, the multiple clamping plates clamp and fix the hydraulic rod. In addition, through the provision of anti-slip rubber blocks, on the one hand, the clamping plates can effectively prevent the hydraulic rod from sliding between the multiple clamping plates when fixing the hydraulic rod. On the other hand, it can also prevent the clamping plates from directly clamping the hydraulic rod, causing damage to the outside of the clamping rod.

[0021] 3. Compared with the existing device, after completing the initial assembly between a hydraulic rod and a cylinder, the present invention utilizes the transposition between multiple hydraulic rods and realizes the rotation of the cylinder through the first bevel gear and the second bevel gear, so that the cylinder to be docked and the hydraulic rod to be installed are transposed at the same time, thereby maintaining the same axis to complete the subsequent docking assembly.

[0022] 4. The present invention rotates the shaft to replace multiple hydraulic rods with the cylinder to complete continuous assembly. The rotation of the shaft can also drive the cam to rotate. When the cam rotates, it drives the push-pull plate to rotate. When the push-pull plate rotates, the built-in rod slides in the end plate. At this time, the end plate drives the piston rod to compress the air cylinder. At this time, the air pressure of the air cylinder is transmitted to the storage box through the air transmission pipe. After the pressure in the storage box increases, the hydraulic rod inside it is transported to the nozzle through the delivery pipe, and finally the hydraulic oil is sprayed on the inner wall of the rubber ring through the nozzle.

[0023] 5. The present invention, through the arrangement of the arc plate and the connecting plate, can ensure that when the multiple movable plates drive the multiple abutment plates to move away from or towards each other, the nozzle is always located between two adjacent abutment plates, so as to meet the requirements of hydraulic oil spraying for rubber rings of different specifications.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] As attached Figures 1-9As shown, a workbench for assembling a hydraulic cylinder comprises a base 1, a cross plate 11 is rotatably mounted on the middle of the upper end surface of the base 1, a plurality of placement tubes 2 for placing the cylinder barrel when assembling the hydraulic cylinder are provided on the upper end surface of the cross plate 11, a side plate 12 is fixedly mounted on one side of the base 1, a lifting frame 14 is slidably mounted on the side plate 12 through an electric slider, a ring frame 30 is fixedly mounted on one side of the lifting frame 14, a transposition plate 33 is rotatably mounted on the middle part of the ring frame 30, a plurality of fixed tubes 36 for placing the hydraulic rod when assembling the hydraulic cylinder are fixedly mounted on the outer extension of the transposition plate 33, a hanging plate 5 is fixedly mounted on the upper part of the lifting frame 14, and the lower end surface of the hanging plate 5 is fixedly mounted. A storage box 50 for storing lubricating oil is fixedly installed, and a lower cylinder 51 is fixedly installed on the lower end surface of the storage box 50. A plurality of movable plates 52 are slidably installed on the outer wall of the lower cylinder 51. An abutment plate 53 for placing the rubber ring is fixedly installed on one end of the movable plate 52. A nozzle 64 is provided between every two adjacent abutment plates 53. A delivery pipe 65 is installed between the nozzle 64 and the storage box 50. An air cylinder 502 is also provided on the hanging plate 5. An air transfer pipe 505 connected to the storage box 50 is fixedly installed on one end of the air cylinder 502. A piston rod 503 is slidably installed in the middle of the air cylinder 502, and an end plate 504 is provided on the piston rod 503.

[0038] By rotating the cross plate 11, it is convenient to replace the multiple cylinders, so that the multiple cylinders and the hydraulic rods can be continuously assembled, thereby improving the work efficiency during the assembly of the hydraulic cylinders and facilitating batch production operations. The electric slider is opened to drive the lifting frame 14 to move downward. When the lifting frame 14 moves downward, the hydraulic rod and the cylinder can be docked and installed. The rubber ring can be tightened by the arrangement of multiple abutment plates 53. The inner wall of the tightened and expanded rubber ring can be evenly sprayed with hydraulic oil by the arrangement of the nozzle 64, so that the rubber ring can be installed on the outside of the hydraulic rod after the oiling operation is completed. The air transmission pipe 505 can be arranged to pump the air in the storage box 50 when the cross plate 11 rotates. When the pressure increases and the air pressure in the storage box 50 increases, the hydraulic oil in the storage box 50 is transmitted to the nozzle 64 through the delivery pipe 65, and finally sprayed to the inner wall of the rubber ring through the nozzle 64. When the rubber ring completes the oil spraying operation, the rubber ring is manually pushed down so that the rubber ring is accurately installed on the hydraulic rod. Then, the hydraulic rod and the cylinder barrel are docked and assembled by rotating the transposition plate 33. Compared with the existing device, the present invention can automatically spray the hydraulic oil on the inside of the rubber ring when assembling the hydraulic cylinder, and after the rubber ring is sleeved on the outside of the hydraulic rod, the hydraulic rod is moved down to be assembled with the fixed cylinder barrel, thereby realizing the assembly of the hydraulic cylinder.

[0039] As attached Figure 1As shown, a rotating column 10 is fixedly installed in the middle of the lower end surface of the cross plate 11, and the rotating column 10 is rotatably connected to the base 1. A lifting groove 13 is opened in the center of the side plate 12, and the lifting frame 14 is slidably connected in the lifting groove 13 through an electric slider. A motor 31 is fixedly installed on one side of the annular frame 30, and the output end of the motor 31 is fixedly connected to the transposition plate 33. A built-in plate 35 is fixedly installed on the side of the fixed cylinder 36 close to the transposition plate 33, and a guide plate 34 is provided on the side of the built-in plate 35 away from the fixed cylinder 36, and the built-in plate 35 is slidably connected in the guide plate 34 through an electric slider.

[0040] When the hydraulic rod and the cylinder are docked and assembled, the electric slider drives the lifting frame 14 to move downward in the lifting groove 13. When the lifting frame 14 moves downward, it can drive the hydraulic rod to move downward until the hydraulic rod applies downward pressure to the cylinder, thereby completing the assembly of the hydraulic rod and the cylinder. The motor 31 is turned on to drive the transposition plate 33 to rotate. When the transposition plate 33 rotates, multiple hydraulic rods can be rotated and transposed, thereby facilitating the continuous assembly of the hydraulic rod and the cylinder.

[0041] As attached Figure 5 As shown, an adjusting ring 37 is rotatably installed on the outside of the fixed cylinder 36 through an electric slider, and a plurality of pushing plates 38 arranged at equal intervals are rotatably installed on the outer extension of the adjusting ring 37. A moving rod 39 is rotatably installed on the side of the pushing plate 38 away from the adjusting ring 37. The moving rod 39 passes through and slides in the fixed cylinder 36. A clamping plate 390 is fixedly installed on one end of the moving rod 39, and an anti-slip rubber block is provided on one side of the clamping plate 390.

[0042] Manually place the bottom of the hydraulic rod into the middle of the fixed cylinder 36, then control the electric slider to open and drive the regulating ring 37 to rotate. When the regulating ring 37 rotates, it drives multiple pushing plates 38 to rotate. When the pushing plates 38 rotate, they drive multiple moving rods 39 to slide on the fixed cylinder 36. When the multiple moving rods 39 move close to each other, the multiple clamping plates 390 clamp and fix the hydraulic rod, and through the setting of the anti-slip rubber block, on the one hand, the clamping plate 390 can effectively prevent the hydraulic rod from sliding between the multiple clamping plates 390 when fixing the hydraulic rod. On the other hand, it can also prevent the clamping plate 390 from directly clamping the hydraulic rod, causing damage to the outside of the clamping rod.

[0043] As attached Figure 1 、 Figure 3As shown, a rotating shaft 32 that passes through and slides on the annular frame 30 is fixedly installed on the side of the transposition plate 33 away from the motor 31, and a first bevel gear 45 is fixedly installed on one side of the rotating shaft 32. A fixing sleeve 41 fixedly connected to the side plate 12 is provided below the first bevel gear 45. A rotating ring 42 is rotatably installed in the middle of the fixing sleeve 41. A plurality of circumferentially arranged rectangular grooves 43 are provided on the side of the rotating ring 42 away from the fixing sleeve 41. Rectangular bars 44 are provided in the rectangular grooves 43. A telescopic rod 4 is installed on one side of the plurality of rectangular bars 44. The bottom of the telescopic rod 4 is rotatably connected to the base 1. A second bevel gear 46 is fixedly installed on the telescopic end of the telescopic rod 4, and the second bevel gear 46 is meshed with the first bevel gear 45.

[0044] After the hydraulic rod on one side is completed with the docking assembly of the cylinder, the motor 31 is turned on to drive the transposition plate 33 to rotate, so that the multiple hydraulic rods are transposed, thereby realizing the feeding of the hydraulic rod so that the next hydraulic rod can be docked and assembled with the cylinder. When the transposition plate 33 rotates, it can also drive the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it drives the first bevel gear 45 to rotate. The first bevel gear 45 drives the telescopic rod 4 to rotate by engaging with the second bevel gear 46. When the telescopic rod 4 rotates, it synchronously drives the rotating ring 42 to rotate. Since the fixed sleeve 41 is fixedly connected to the lifting frame 14, when the lifting frame 14 moves downward as a whole, due to the arrangement of the rectangular bar 44 and the rectangular groove 43, the fixed sleeve 41 drives the rotating ring 42 and the rectangular bar 44 to move downward. At this time, the telescopic end of the telescopic rod 4 synchronously drives the second The bevel gear 46 moves downward, so that the second bevel gear 46 is always meshed with the first bevel gear 45, while not affecting the rotation of the telescopic rod 4 and the rotating ring 42 inside the fixed sleeve 41. When the telescopic rod 4 rotates, the setting of the pulley and the belt can synchronously drive the rotating column 10 to rotate. When the rotating column 10 rotates, the cross plate 11 is synchronously driven to rotate, thereby realizing the transposition between the cylinders. Compared with the existing device, after completing the initial assembly between a hydraulic rod and a cylinder, the present invention utilizes the transposition between multiple hydraulic rods to realize the rotation of the cylinder through the first bevel gear 45 and the second bevel gear 46, so that the cylinder to be docked and the hydraulic rod to be installed are transposed at the same time, thereby maintaining the same axis to complete the subsequent docking assembly.

[0045] As attached Figure 1 、 Figure 4 As shown, a cam 507 is fixedly mounted on the rotating shaft 32, a push-pull plate 508 is rotatably mounted on one side of the cam 507, a built-in rod 509 is fixedly mounted on one side of the push-pull plate 508, a groove arranged in an arc shape is opened on the end plate 504, one side of the built-in rod 509 is inserted into the groove and slides, and a one-way valve 506 is provided on the air transmission tube 505.

[0046] When the rotating shaft 32 rotates to cause multiple hydraulic rods and cylinders to be replaced in order to complete continuous assembly, the rotation of the rotating shaft 32 can also drive the cam 507 to rotate. When the cam 507 rotates, it drives the push-pull plate 508 to rotate. When the push-pull plate 508 rotates, the built-in rod 509 slides in the end plate 504. At this time, the end plate 504 drives the piston rod 503 to compress the air cylinder 502. At this time, the air pressure of the air cylinder 502 is transmitted to the storage box 50 through the air transmission pipe 505. After the pressure in the storage box 50 increases, the hydraulic rod inside it is transported to the nozzle 64 through the delivery pipe 65, and finally the hydraulic oil is sprayed on the inner wall of the rubber ring through the nozzle 64.

[0047] Pulleys are installed at the bottom of the telescopic rod 4 and the bottom of the rotating column 10, and a belt is installed between the pulleys.

[0048] Both sides of the lower cylinder 51 are hinged with an arc-shaped plate 6, and a cam 60 is fixedly installed on one side of the upper end surface of the arc plate 6. A connecting plate 61 is provided between two adjacent cams 60. Both sides of the connecting plate 61 are provided with symmetrically arranged sleeve grooves 62. The sleeve grooves 62 are located on the outside of the corresponding cam 60 below and are sleeved thereon. A special-shaped frame 63 is fixedly installed in the middle of the lower end surface of the connecting plate 61, and the nozzle 64 is fixedly connected to the special-shaped frame 63.

[0049] By setting the arc plate 6 and the connecting plate 61, when the multiple movable plates 52 drive the multiple abutment plates 53 to move away from or towards each other, the nozzle 64 is always located between two adjacent abutment plates 53, so as to meet the requirements of hydraulic oil spraying for rubber rings of different specifications.

[0050] As attached Figure 2 As shown, the middle part of the placing cylinder 2 is provided with a groove and a side groove 20 connected to its inner cavity is provided on one side of the placing cylinder 2. A plurality of circumferentially arranged top grooves 21 are provided on the upper end surface of the placing cylinder 2. A vertical plate 22 is slidably installed in the top groove 21. A cylinder 23 fixedly connected to the placing cylinder 2 is provided on one side of the side groove 20. A connecting frame 24 is fixedly installed on the telescopic end of the cylinder 23. One side of the connecting frame 24 is arc-shaped and fixed to the bottom of the plurality of vertical plates 22. A sliding rod 221 is slidably installed on the middle part of the upper side of the vertical plate 22. A limiting plate 222 is fixedly installed on one end of the sliding rod 221. A spring is provided on the outside of the sliding rod 221.

[0051] The cylinder 23 is opened and retracted to drive the connecting frame 24 to slide in the side groove 20. When sliding, the connecting frame 24 simultaneously drives multiple vertical plates 22 to slide in the top groove 21. At this time, multiple sliding rods 221 drive multiple limiting plates 222 to approach each other under the action of springs to limit the top edge of the cylinder, thereby completing the restriction of the top of cylinders of different specifications.

[0052] As attached Figure 7As shown, an electric push rod 511 is fixedly installed on the top of the inner cavity of the lower cylinder 51, and a conical block 512 with an inverted trapezoidal cross-section is fixedly installed on the telescopic end of the electric push rod 511. A plurality of circumferentially arranged wedge blocks 513 are provided on the outside of the conical block 512, and the plurality of wedge blocks 513 are respectively fixedly connected to the plurality of movable plates 52.

[0053] The electric push rod 511 is turned on and pushed down. At this time, the conical block 512 moves down synchronously with the electric push rod 511. When the conical block 512 moves down, it squeezes the multiple wedge blocks 513. At this time, after being squeezed, the multiple wedge blocks 513 drive the multiple moving plates 52 to move away from each other. When the multiple moving plates 52 move away from each other, they drive the multiple abutment plates 53 to move away from each other, thereby completing the tightening and expansion of the rubber ring.

[0054] A chuck for fixing cylinders of different specifications is provided in the placement tube 2. When multiple cylinders are docked and assembled with multiple hydraulic rods, the cylinders and their corresponding hydraulic rods always have the same axis.

[0055] During use, the setting of multiple abutment plates 53 can tighten the rubber ring, and the setting of the nozzle 64 can evenly spray the hydraulic oil on the inner wall of the tightened and expanded rubber ring, so that the rubber ring can be installed on the outside of the hydraulic rod after the oiling operation is completed. The setting of the air transmission pipe 505 can increase the air pressure in the storage box 50 when the cross plate 11 rotates. When the air pressure in the storage box 50 increases, the hydraulic oil in the storage box 50 is transmitted to the nozzle 64 through the delivery pipe 65, and finally sprayed to the inner wall of the rubber ring through the nozzle 64. When the rubber ring completes the oil spraying operation, the rubber ring is manually pushed down so that the rubber ring is accurately installed on the hydraulic rod. Then, the hydraulic rod with the rubber ring assembled is docked and assembled with the cylinder by rotating the transposition plate 33. Compared with the existing device, the present invention can automatically align the rubber ring when assembling the hydraulic cylinder. Hydraulic oil is sprayed inside the ring, and after a rubber ring is sleeved on the outside of the hydraulic rod, the hydraulic rod is moved down to be assembled with the fixed cylinder, thereby realizing the assembly of the hydraulic cylinder, and the bottom of the hydraulic rod is manually placed in the middle of the fixed cylinder 36, and then the electric slider is controlled to open and drive the regulating ring 37 to rotate. When the regulating ring 37 rotates, it drives multiple pushing plates 38 to rotate, and when the pushing plates 38 rotate, it drives multiple moving rods 39 to slide on the fixed cylinder 36. When the multiple moving rods 39 move close to each other, the multiple clamping plates 390 clamp and fix the hydraulic rod, and the provision of the anti-slip rubber block can, on the one hand, effectively prevent the hydraulic rod from sliding between the multiple clamping plates 390 when fixing the hydraulic rod, and on the other hand, it can also prevent the clamping plate 390 from directly clamping the hydraulic rod, causing damage to the outside of the clamping rod;

[0056] After the hydraulic rod on one side completes the docking and assembly with the cylinder, the motor 31 is turned on to drive the transposition plate 33 to rotate, so that the multiple hydraulic rods are transposed, thereby realizing the feeding of the hydraulic rod so that the next hydraulic rod can be docked and assembled with the cylinder. When the transposition plate 33 rotates, it can also drive the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it drives the first bevel gear 45 to rotate. The first bevel gear 45 drives the telescopic rod 4 to rotate by engaging with the second bevel gear 46. When the telescopic rod 4 rotates, it synchronously drives the rotating ring 42 to rotate. Since the fixed sleeve 41 is fixedly connected to the lifting frame 14, when the lifting frame 14 moves downward as a whole, due to the setting of the rectangular bar 44 and the rectangular groove 43, the fixed sleeve 41 drives the rotating ring 42 and the rectangular bar 44 to move downward. At this time, the telescopic end of the telescopic rod 4 synchronously drives the second bevel gear 46. The gear 46 moves downward, so that the second bevel gear 46 is always meshed with the first bevel gear 45, while not affecting the rotation of the telescopic rod 4 and the rotating ring 42 inside the fixed sleeve 41. When the telescopic rod 4 rotates, the setting of the pulley and the belt can synchronously drive the rotating column 10 to rotate. When the rotating column 10 rotates, the cross plate 11 is synchronously driven to rotate, thereby realizing the transposition between the cylinders. Compared with the existing device, after completing the initial assembly between a hydraulic rod and the cylinder, the present invention utilizes the transposition between multiple hydraulic rods to realize the rotation of the cylinder through the first bevel gear 45 and the second bevel gear 46, so that the cylinder to be docked and the hydraulic rod to be installed are transposed at the same time, thereby maintaining the same axis to complete the subsequent docking assembly.

[0057] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
