Description

Technical Field

[0001] The present invention relates to the technical field of cylinder installation equipment, and more specifically, to a hydraulic cylinder installation equipment and an assembling method thereof. Background Art

[0002] A hydraulic cylinder is a device that uses liquid pressure energy to transmit force and motion. It is commonly used in industrial machinery and equipment. It consists of a sealed cylindrical cylinder and a piston that can slide in the cylinder. When hydraulic oil is pumped into one side of the cylinder, the pressure of the oil pushes the piston to the other side, thereby generating linear motion.

[0003] At present, the hydraulic cylinder installation equipment on the market is usually installed using a gantry lathe. First, the cylinder body is placed inside the base of the gantry lathe, and then the piston is moved to the top of the cylinder body. The cylinder installation equipment is moved above the piston, and the piston is pressed into the inside of the cylinder body through the cylinder output end. The cylinder output end is then retracted, and the threaded installation components are placed in the threaded support position of the piston. The cylinder output end is then extended and rotated to tighten the piston in the cylinder body to complete the installation of the hydraulic cylinder.

[0004] When the piston is placed on the cylinder body, only a part of the bottom of the piston is inside the cylinder body, and the longer part of the piston is exposed to the air. During this time, the piston will tilt to the surroundings due to its own gravity, and the current installation of the piston is flat. If it encounters an arc surface or other shapes of the piston end, it is not applicable. When the output end of the cylinder contacts the top of the piston, the arc surface shape will cause the piston to have only one force point, causing the piston to shift. If the output end of the cylinder continues to press downward, the piston will be subjected to stress in different directions, damaging the shape of the piston. If the position of the punch head needs to be adjusted, the axis line of the output end of the cylinder will be offset from the axis line of the cylinder body. The downward stamping of the output end of the cylinder will cause uneven force on the piston. Summary of the invention

During this time, the piston will tilt to the sides due to its own gravity, causing the initial position of the piston to shift when installed in the cylinder, resulting in defective products.

[0060] See also Figures 1 to 7 and Fig.17 The support unit 2 includes a support frame 21, which is in the shape of an inverted U shape. The two protection units 4 are respectively installed at the two inverted legs of the U shape of the support frame 21. A support plate 22 is installed above the support frame 21. The support plate 22 is in the shape of a rectangular hollow. Support columns 23 are respectively installed at the two sides below the support plate 22 and in the middle of the two protection units 4. A connecting support block 24 is connected and installed in the middle of the two support columns 23. The support frame 21, the support plate 22, and the support column 23 cooperate to provide auxiliary installation support for the protection unit 4.

[0061] The cylinder unit 7 includes a cylinder 71, a cylinder head 72 is installed below the cylinder 71, the hydraulic cylinder product 3 includes a cylinder body 31, a piston 32 is arranged above the cylinder body 31, a threaded part and a supporting part are arranged at the bottom of the piston 32, the threaded part fits with the inside of the cylinder body 31, the cylinder head 72 is arranged below the connecting support block 24, the connecting support block 24 is used to assist in supporting and positioning the cylinder head 72, when the output end of the cylinder 71 is extended, the cylinder head 72 is driven to move, and the connecting support block 24 is synchronously driven to slide on the two support columns 23, and the cylinder 71 is located at the rectangular through hole position of the support plate 22.

[0062] See also Figures 1 to 7 The base unit 1 includes an equipment base 11, which is in the shape of a rectangular groove. Equipment cylinders 12 are equidistantly installed on both sides of the equipment base 11. Clamping blocks 14 are installed at the output ends of the equipment cylinders 12. The shape of the clamping blocks 14 is special-shaped. Equipment slide rails 13 are installed on both sides of the upper part of the equipment base 11. Slide blocks 15 are provided on the equipment slide rails 13. Sliding motors 16 are provided at one end of the equipment slide rails 13. The cylinder body 31 is equidistantly placed in the middle position of the equipment base 11, and then the clamping blocks 14 are extended out by the corresponding equipment cylinders 12 on both sides. The two clamping blocks 14 are respectively attached to the corresponding outer walls of the cylinder body 31, and then the cylinder body 31 is clamped. The clamping blocks 14 are attached to the cylinder body 31 to ensure that the cylinder body 31 can remain stable during the subsequent cylinder installation operation.

[0063] See also Figures 1 to 7 The protection unit 4 includes a protection frame 41, a lifting cylinder 42 is installed in the middle position of the protection frame 41, and a supporting mechanism 43 is installed at the output end of the lifting cylinder 42. The supporting mechanism 43 includes a connecting arc plate 431, and a supporting arc plate 433 is arranged on the side of the connecting arc plate 431 away from the protection frame 41. Buffer springs 432 are equidistantly arranged in a ring between the connecting arc plate 431 and the supporting arc plate 433. When the support unit 2 moves to the top of the cylinder body 31, the output ends of the two lifting cylinders 42 extend out, and synchronously drive the supporting mechanism 43 to extend, which can limit the piston 32 to the middle position. The two supporting mechanisms 43 form a circle. The diameter of the circle formed by the two supporting arc plates 433 is larger than the cylindrical diameter of the piston 32, allowing the piston 32 to move in the supporting mechanism 43. If the piston 32 shakes in the supporting mechanism 43, the supporting mechanism 43 can limit the position of the piston 32, and the buffer spring 432 can reduce the shaking stress of the piston 32.

[0064] By setting the circular diameter formed by the two supporting arc plates 433 to be larger than the cylindrical diameter of the piston 32, when the piston 32 shakes in the supporting mechanism 43, the supporting mechanism 43 can limit the position of the piston 32, and the buffer spring 432 reduces the shaking stress of the piston 32, thereby achieving the effect of limiting the position of the piston 32 in the cylinder body 31 and correcting the position of the piston 32.

[0065] Embodiment 2: Since the current installation of pistons is flat, it is not applicable if the piston end is an arc surface or other shapes. When the output end of the oil cylinder contacts the top of the piston, the arc surface shape will cause the piston to have only one force point, causing the piston to shift. If the output end of the oil cylinder continues to press downward, the piston will be subjected to stress in different directions, damaging the shape of the piston. If the position of the punch head needs to be adjusted, the axis line of the output end of the oil cylinder will shift from the axis line of the cylinder body. The downward stamping of the output end of the oil cylinder will cause uneven force on the piston.

[0066] See also Figures 8 to 11 A press unit 5 is installed above the support unit 2. The press unit 5 includes an adjustment mechanism 51 and a cylinder mechanism 52. The adjustment mechanism 51 can drive the cylinder unit 7 to move. A cylinder mechanism 52 is installed below the cylinder head 72. The cylinder mechanism 52 includes a cylinder block 521. The cylinder block 521 is arranged below the cylinder head 72. The cylinder block 521 is a cylindrical groove. A cylinder plate 522 is installed at one end of the groove of the cylinder block 521. Adaptation modules 523 are equidistantly arranged on the cylinder plate 522. The adaptation module 523 includes a limit plate 5231. The limit plate 5231 is away from An adaption column 5232 is installed at one end of the cylinder block 521, and an adaption head 5233 is provided at the end of the adaption column 5232 away from the limit plate 5231. The shape of the adaption head 5233 is to avoid scratching the contact part of the piston 32 when the piston 32 comes into contact. The shape of the adaption head 5233 can be stuck on the top of the cylinder plate 522 to prevent the adaption column 5232 from slipping. When the adaption module 523 comes into contact with the piston 32, the contact part of the adaption module 523 moves toward the inside of the cylinder block 521, and the shape of the adaption module 523 can match the shape of the piston 32.

[0067] By setting the adaptation module 523 in contact with the piston 32, the adaptation module 523 in the contact part shrinks into the inside of the cylinder block 521, while the adaptation module 523 in the non-contact part continues to remain in the extended state. In this state, the shape formed by the cooperation of multiple adaptation modules 523 is matched with the shape of the piston 32, thereby achieving the effect of automatically adapting to the shape of the contact surface of the piston 32.

[0068] See also Figures 8 to 11 and Fig.17 , adjust the axial centerline position of the cylinder unit 7, the adjustment mechanism 51 includes an adjustment module 511, the adjustment module 511 is installed above the support plate 22, a rectangular through hole is set in the middle of the support plate 22, an adjustment connecting frame 512 is installed on the adjustment module 511, an adjustment slider 513 is slidably installed on the adjustment connecting frame 512, a mounting plate 514 is installed on the adjustment slider 513, and the cylinder unit 7 is installed in the rectangular through hole formed by the adjustment slider 513 and the mounting plate 514.

In the rectangular through hole formed with the mounting plate 514, the adjustment module 511 includes two adjustment rails and an adjustment motor. The two adjustment rails are respectively installed on both sides of the support plate 22. The adjustment motor can drive the adjustment connecting frame 512 to move, and the adjustment slider 513 can move on the adjustment connecting frame 512. When the shape of the adaptation module 523 matches the shape of the piston 32, the central axis of the piston 32 and the center axis of the cylinder unit 7 may be offset due to pressure. The central axis of the piston 32 is aligned with the center axis of the cylinder unit 7 through the adjustment mechanism 51.

[0069] By setting an adjusting connecting frame 512 on which an adjusting slider 513 is slidably installed, and a mounting plate 514 is installed on the adjusting slider 513, the adjusting motor drives the adjusting connecting frame 512 to move, and the adjusting slider 513 moves on the adjusting connecting frame 512, so that the cylinder unit 7 and the cylinder mechanism 52 are displaced synchronously, thereby achieving the effect of aligning the central axis of the piston 32 with the center axis of the cylinder unit 7 and making the stress uniform.

[0070] In the third embodiment, when the piston is pressed onto the bottom of the cylinder at the output end of the oil cylinder, when the piston is tightened in the cylinder, friction will occur between the bottom of the piston and the inner bottom of the cylinder, scratching the bottom of the cylinder or rubbing the piston, causing rust inside the cylinder.

When the driving bevel tooth 63 rotates, the driven tooth 68 is synchronously driven to rotate.

[0072] See also Figures 12 to 17 A first connecting mechanism 64 and a second connecting mechanism 65 are installed on the fixed wheel 67.

When the piston 32 is pressed to the bottom of the cylinder body 31, the first motor 641 drives the first driving tooth 642 to rotate and extends the first connecting plate 643 toward the position of the piston 32. The second motor 651 drives the second driving tooth 652 to rotate and extends the second connecting plate 653 toward the position of the piston 32. The first connecting plate 643 and the second connecting plate 653 are matched, and the cylinder unit 7 contracts upward to move the piston 32 partly upward.

[0074] By setting the output end of the first motor 641 to drive the first driving tooth 642 to rotate, the first driving tooth 642 drives the first locking tooth 644 to move, and drives the first connecting plate 643 to move toward the middle through hole position of the piston 32; the output end of the second motor 651 drives the second driving tooth 652 to rotate, the second driving tooth 652 drives the second locking tooth 654 to move, and drives the second connecting plate 653 to move toward the middle through hole position of the piston 32; the contact part of the first connecting plate 643 and the second connecting plate 653 is plugged in, so as to achieve the effect of being able to lift out a part of the piston 32, thereby avoiding the problem of friction between the bottom of the piston 32 and the cylinder body 31.

[0075] Since the piston 32 is partially raised, the mounting unit 6 is now connected to the piston 32 , and the original external tightening elements are no longer applicable, and the original elements need to be constantly disassembled, which is not suitable for the existing automation structure.

[0076] See also Figures 12 to 17A clamping mechanism 66 is installed below the driven tooth 68, and the clamping mechanism 66 includes a first clamping plate 661, and a second clamping plate 662 is arranged below the first clamping plate 661. Telescopic rods 663 are equidistantly arranged in the middle ring between the first clamping plate 661 and the second clamping plate 662, and a clamping plate 664 is installed at the output end of the telescopic rod 663. When the clamping mechanism 66 is at the position of the threaded support part of the piston 32, the output end of the telescopic rod 663 extends out, and the clamping plate 664 clamps the threaded support part of the piston 32. The driving motor 62 drives the driving bevel gear 63 to rotate, and at the same time, the cylinder 71 follows and extends downward to tighten the threaded part of the piston 32 in the cylinder body 31.

[0077] By extending the output end of the telescopic rod 663, the clamping plate 664 clamps the threaded support portion of the piston 32, and the driving motor 62 drives the driving bevel gear 63 to rotate, and the threaded portion of the piston 32 is tightened in the cylinder body 31, thereby achieving the effect of directly tightening the piston 32 inside the cylinder body 31 without the need for continuous disassembly.
