Description

Technical Field

[0001] The invention relates to the technical field of hydraulic cylinder processing, in particular to a hydraulic cylinder body and manufacturing and processing equipment thereof. Background Art

[0002] The hydraulic cylinder is an actuator in the hydraulic system. The hydraulic cylinder pushes the piston rod through the pressure of the hydraulic oil to achieve linear reciprocating motion, converting hydraulic energy into mechanical energy to complete various complex operations. It is widely used in various heavy machinery and equipment. For example, in crane equipment, the hydraulic system is an important component to realize its various actions and functions. It is mainly used to realize the lifting, extension, rotation and other actions of the crane. The cylinder body is the main pressure-bearing component of the hydraulic cylinder, usually made of high-strength steel or cast iron. The inner wall of the cylinder body is precisely processed and polished to ensure that the piston has less friction and good sealing performance during movement. The main function of the cylinder body is to withstand the pressure of the hydraulic oil to form a closed working chamber.

[0003] Among them, milling the surface of the cylinder is a precision machining process, which requires milling the inner and outer walls of the cylinder body. Although the traditional method of synchronous milling of the inner and outer walls of the cylinder body has improved the machining efficiency to a certain extent, it also has some disadvantages: when performing synchronous milling of the inner and outer walls, it is necessary to adjust the positions of the outer milling cutter and the inner milling cutter in turn according to the thickness of the cylinder body, and lock the limit. This process is complicated and time-consuming, especially for cylinder bodies with different cylinder wall thickness specifications, which require frequent adjustments.

[0004] In addition, in the traditional milling process, the steps of clamping and driving the cylinder body to rotate are usually separate and need to be completed separately, which means that before milling, the cylinder body needs to be fixed on the fixture, and then connected to the rotating device, and finally driven by an additional transverse movement device to move the cylinder body laterally before milling can be performed. This decentralized process increases the complexity of the operation, and multiple adjustments and operations are prone to errors, affecting the milling accuracy and processing quality.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] See also Figure 1 and Figure 2The present invention provides a technical solution: a hydraulic cylinder body, including a cylinder barrel 100, an upper end flange 200 is fixedly connected to the upper end port of the cylinder barrel 100, a lower end flange 300 is fixedly connected to the lower part of the outer wall of the cylinder barrel 100, an oil outlet nozzle 110 is connected to the upper part of the cylinder barrel 100, and an oil inlet nozzle 120 is connected to the lower part of the cylinder barrel 100. In addition, the present invention also provides a hydraulic cylinder body manufacturing and processing equipment, which is mainly used for synchronous milling of inner and outer walls of the hydraulic cylinder body. The hydraulic cylinder body manufacturing and processing equipment includes a processing table 1, and a clamping mechanism 2 for clamping and limiting the outer part of the hydraulic cylinder body is installed on the upper end surface of the processing table 1. An end clamping mechanism 3 for contacting and clamping the end of the hydraulic cylinder body is arranged on the clamping mechanism 2, and an adaptive wall contacting mechanism 4 for synchronously contacting the inner and outer walls of the hydraulic cylinder body for synchronous milling is installed on the right part of the upper end surface of the processing table 1.

[0030] See also Figure 2 , Figure 3 and Figure 4 In this embodiment, the adaptive wall-contacting mechanism 4 includes a linkage transverse moving part 42 arranged on the clamping mechanism 2 and transmission-connected to the end clamping mechanism 3, a strip mounting plate 41 arranged on the upper part of the linkage transverse moving part 42, a screw rod 43 rotatably connected to the middle part of the right end surface of the strip mounting plate 41, two sliding grooves 44 symmetrically arranged on the strip mounting plate 41, two No. 1 sliding blocks 45 symmetrically connected to the sliding grooves 44, an inner milling cutter 46 fixedly connected to the left end surface of the No. 1 sliding block 45, two No. 2 sliding blocks 47 symmetrically connected to the sliding grooves 44, and an outer milling cutter 410 fixedly connected to the left end surface of the No. 2 sliding block 47, and two self-stop components are arranged outside the screw rod 43. 48, a No. 1 connecting rod 411 is hinged between the self-stop component 48 located on the left and the No. 1 sliding block 45, the screw rod 43, the self-stop component 48 located on the left and the No. 1 connecting rod 411 are combined to push the inner milling cutter 46 to move away from each other, the self-stop component 48 located on the right is symmetrically arranged on the front and back of the outside with push rods 412, and a No. 2 connecting rod 413 is hinged between one end of the push rod 412 away from the self-stop component 48 and the No. 2 sliding block 47, the screw rod 43, the self-stop component 48 located on the right and the No. 2 connecting rod 413 are combined to push the outer milling cutter 410 to move towards each other, and a non-return unit 49 for limiting the self-stop component 48 in one direction is installed on the right side of the strip mounting plate 41.

[0031] See also Figure 5 The self-stop assembly 48 includes a screw ring 481 threadedly connected to the outside of the screw rod 43, and a ring 482 is rotatably connected to the outside of the screw ring 481. The inner wall of the ring 482 is provided with a plurality of arc grooves at equal intervals. The groove wall on one side of each arc groove away from the screw ring 481 is slidably connected to an arc friction plate 484 that contacts the outer wall of the screw ring 481 through a pressure spring 483.

[0032] See also Figure 4 and Figure 5 The non-return unit 49 includes two strip plates 491 symmetrically fixedly connected to the right end surface of the strip mounting plate 41 by connecting rods, and a plurality of slots 492 with triangular longitudinal sections are equidistantly provided on opposite sides of the two strip plates 491. A U-shaped frame 493 is symmetrically fixedly connected to the outer wall of the ring 482, and a rectangular slot is provided in the vertical section of the U-shaped frame 493. A slot wall on one side of the rectangular slot close to the ring 482 is slidably connected to a clamping column 495 for cooperating with the slot 492 through a limit spring 494.

[0033] Before milling the hydraulic cylinder body, the cylinder body wall is moved so that it is located between the outer milling cutter 410 and the inner milling cutter 46. The screw rod 43 is then manually rotated to push the arc friction plate 484 against the outside of the screw ring 481 through the pressure spring 483, so that there is a large friction force between the arc friction plate 484 and the screw ring 481. The friction force between the two is used to make the screw ring 481 remain stationary relative to the ring 482 during the rotation and adjustment of the screw rod 43, so that the screw ring 481 connected to it with a thread moves to the left during the rotation of the screw rod 43, and the screw ring 481 then drives the ring 482 to move to the left synchronously. When the ring 482 on the left moves to the left, it pushes the No. 1 connecting rod 411 to expand and move toward the front and rear sides. The No. 1 connecting rod 411 then pushes the two inner milling cutters 46 away from each other through the No. 1 sliding block 45 until the inner milling cutter 46 touches the inner wall of the hydraulic cylinder body.

[0034] When the ring 482 on the right moves to the left, it will drive the push rod 412 to move synchronously. The push rod 412 then pushes the two No. 2 sliding blocks 47 to move closer to each other through the No. 2 connecting rod 413. The No. 2 sliding block 47 then drives the external milling cutter 410 to move closer to each other until the external milling cutter 410 touches the outer wall of the hydraulic cylinder. In this way, the positions of the inner and outer milling cutters 410 can be adjusted at the same time, and the spacing adjustment of the inner and outer walls can be completed at one time, avoiding the position adjustment steps that need to be adjusted separately and in sequence in the traditional method, thereby simplifying the operation steps.

[0035] In the process of adjusting the movement of the inner milling cutter 46 and the outer milling cutter 410 to make them contact with the outer wall of the cylinder body, when the inner milling cutter 46 touches the inner wall of the hydraulic cylinder body and the outer milling cutter 410 has not yet contacted the outer wall of the hydraulic cylinder body: the inner milling cutter 46 that touches the inner wall of the hydraulic cylinder body will stop moving. At this time, the screw 43 is continued to be controlled to rotate. Since the inner milling cutter 46 stops moving, the No. 1 connecting rod 411 also stops at this time. The static friction between the spiral ring 481 and the arc-shaped friction plate 484 on the left is changed to sliding friction. The spiral ring 481 on the left now rotates synchronously with the rotation of the screw 43 until the outer milling cutter 410 hits the outer wall of the hydraulic cylinder body. Conversely, if the outer milling cutter 410 Before the inner milling cutter 46 hits the surface wall of the hydraulic cylinder body, the screw ring 481 on the right repeats the above steps. The screw ring 481 on the right changes from being stationary relative to the ring 482 to rotating. As the screw 43 rotates synchronously, the screw ring 481 on the left continues to move to the left until the outer milling cutter 410 and the inner milling cutter 46 finally hit the surface of the hydraulic cylinder body. When one milling cutter hits the inner or outer wall of the cylinder body, it stops moving, and the other milling cutter continues to move until it hits the corresponding wall, ensuring the accurate spacing between the milling cutter and the inner and outer walls of the cylinder body, avoiding errors that may occur during multiple adjustments, ensuring high precision in milling of the inner and outer walls, and improving the surface quality and consistency of the cylinder body machining.

[0036] When the ring 482 is driven by the screw ring 481 to move horizontally to the left, it will also drive the U-shaped frame 493 to move synchronously. The U-shaped frame 493 then drives the clamping column 495 to move to the left. During the movement to the left, the clamping column 495 will pass through the clamping groove 492 through which it passes. The vertical section of the clamping groove 492 with a longitudinal section of a right-angled triangle is used to limit the clamping column 495 after it moves to the left, preventing the clamping column 495 from moving to the right, thereby avoiding the movement of the adjusted inner milling cutter 46 or the outer milling cutter 410, thereby ensuring the milling accuracy.

[0037] See also Figure 2 , Figure 6 and Figure 7 In this embodiment, the clamping mechanism 2 includes two support plates 21 symmetrically fixedly connected to the upper end surface of the processing table 1, the upper part of the support plate 21 located on the right is hinged with an arc-shaped support plate 22, and the upper side of the support plate 21 located on the left is in contact with the lower surface wall of the arc-shaped support plate 22, and two folding rods 23 symmetrically hinged front and back and arranged in an X shape are hinged between the two support plates 21, and the opposite sides of the upper parts of the two folding rods 23 are respectively fixedly connected with arc-shaped clamping plates 24, and the arc-shaped inner walls of the arc-shaped clamping plates 24 and the arc-shaped support plates 22 are respectively equidistantly connected to a plurality of rollers 25 for rotation, and an L-shaped frame 26 is fixedly connected to the left part of the upper end surface of the processing table 1, and the lower end surface of the transverse section of the L-shaped frame 26 is fixedly connected to a lower plate 27 through an electric telescopic rod, and the lower end surface of the lower plate 27 is symmetrically fixedly connected with two lower fork rods 28 for squeezing the folding rods 23.

[0038] When milling the hydraulic cylinder body, place it on the arc-shaped support plate 22, then control the electric telescopic rod to extend and drive the lower plate 27 to move downward, and the lower plate 27 then drives the lower fork rod 28 to move synchronously. The lower fork rod 28 moves downward and touches the folding rod 23 and squeezes the two folding rods 23 to rotate around the hinge, and the folding rod 23 then drives the two arc-shaped clamping plates 24 to move closer to each other until the arc-shaped clamping plates 24 hit the outer wall of the hydraulic cylinder body, thereby completing the clamping of the hydraulic cylinder body. By clamping the hydraulic cylinder body from multiple directions, the stability of its clamping is greatly improved.

[0039] See also Figure 6 , Figure 7 and Figure 8 The cam 36 is provided with a plurality of guide rails 36a and 36b, and a plurality of guide rails 36b are provided on the cam 36b to prevent the cam 36b from sliding out of the cam 36b.

[0040] See also Figure 2 , Figure 3 , Figure 6 and Figure 7The linkage transverse shifting part 42 includes two slide bars 421 symmetrically fixedly connected to the upper end surface of the processing table 1 through the support block, a slide plate 422 slidably arranged on the outer wall of the slide bar 421, and a rotating shaft 423 that penetrates and rotates in the support plate 21. The slide plate 422 is symmetrically provided with slide grooves 424 passed by the slide bar 421, and the slide plate 422 is provided with a waist-shaped groove 425. The right end of the rotating shaft 423 is fixedly connected with a threaded rod 426 that penetrates into the waist-shaped groove 425. The lower groove wall of the waist-shaped groove 425 is slidably connected with the threaded rod 426 through a top spring. The arc plate 427 is threadedly connected to the threaded rod 426, and the driving shaft 31 is transmission-connected to the rotating shaft 423 through the pulley member 428. The strip mounting plate 41 is fixedly connected to the upper end surface of the sliding rod 421. Before milling, the slide plate 422 can be lifted upward and the arc plate 427 can be pulled downward to separate from the threaded rod 426 according to the specific length of the cylinder body. Then, the slide plate 427 can be slid to the appropriate position, and then the slide plate 427 can be put down and the arc plate 427 can be loosened, so that the arc plate 427 is threadedly connected to the threaded rod 426 again.

[0041] When the pressing mechanism 2 is in operation and clamps the cylinder body, it will also trigger the triggering end clamping mechanism 3 to operate synchronously. During the downward movement of the lower plate 27, the matching rod 39 is driven downward. After the matching rod 39 moves downward, it will contact the inclined surface of the conical ring 38 and squeeze it. The conical ring 38 is then squeezed to move to the right and drive the sleeve ring 36 to move. The sleeve ring 36 then pushes the top ring 34 and the spoke frame 33 to move to the right as a whole through the strip rod 37 until the right side of the top ring 34 touches the left part of the cylinder body. Then the conical ring 38 continues to drive the sleeve ring 36 to move to the right, and the sleeve ring 36 then drives the clamping jaws 35 to rotate through the strip rod 37 until the clamping jaws 35 are tightly clamped on the outer wall of the cylinder body. Then the self-driven driving shaft 31 is controlled to rotate, and the driving shaft 31 then drives the top ring 34 to rotate through the sleeve ring 36 and the strip rod 37. The top ring 34 then drives the cylinder body to rotate through the friction between it and the cylinder body and the clamping jaws 35 clamped on the outer wall of the cylinder body.

[0042] At the same time, the driving shaft 31 drives the rotating shaft 423 to rotate through the pulley part 428, and the rotating shaft 423 then drives the threaded rod 426 to rotate. During the rotation of the threaded rod 426, it drives the arc plate 427 threadedly connected to it to move to the left, and the arc plate 427 then drives the slide plate 422 to move to the left. The slide plate 422 then drives the inner milling cutter 46 and the outer milling cutter 410 to gradually move to the left through the strip mounting plate 41, and gradually move deeper into the hydraulic cylinder body, so that the inner and outer walls of the hydraulic cylinder body can be milled synchronously, integrating the clamping, rotation, lateral movement and milling steps, reducing the switching and adjustment time between the steps in the traditional processing process, ensuring the coordination of the various steps in the milling process, and improving the stability and accuracy of the processing. One driving source drives multiple mechanisms to operate, reducing the complexity of operation and making power utilization more efficient.

[0043] See also Figure 6 In this embodiment, the lower end surface of the lower moving plate 27 is fixedly connected with an L-shaped hook rod 5, and the upper end surface of the processing table 1 and the right part of the arc-shaped support plate 22 are rotatably connected with a chip collecting bucket 6 through a support. After the milling of the hydraulic cylinder body is completed, the electric telescopic rod is controlled to contract and drive the lower moving plate 27 to rise, and the upper moving plate rises to separate the arc clamping plate 24 from the cylinder body, and at the same time, it will drive the clamping claw 35 and the top ring 34 to move away from the cylinder body, and then control the inner milling cutter 46 and the outer milling cutter 410 to move out of the hydraulic cylinder. The cylinder body is moved out, the manually rotating support pillar drives the chip collecting bucket 6 to move to the bottom of the right port of the cylinder body, and then the lower plate 27 drives the L-shaped hook rod 5 to rise so that the horizontal section of the L-shaped hook rod 5 contacts the lower part of the arc-shaped support plate 22, and then pulls the arc-shaped support plate 22 to rotate around the upper hinge of the support plate 21 on the left, so that the cylinder body becomes inclined. Finally, the metal chips in the inner cavity of the cylinder body during processing can be discharged under the action of the inclined surface of the cylinder body, and the discharged metal chips fall into the chip collecting bucket 6.

[0044] During operation, the adaptive wall-contacting mechanism 4 is first controlled to operate to adjust the movement of the inner milling cutter 46 and the outer milling cutter 410 according to the thickness of the hydraulic cylinder wall, so that the inner milling cutter 46 and the outer milling cutter 410 respectively contact the corresponding surface walls of the hydraulic cylinder. Then, the clamping mechanism 2 is controlled to operate to clamp and limit the hydraulic cylinder body. At the same time, the end clamping mechanism 3 will also be triggered to operate and connect with the end of the hydraulic cylinder body.
