Description

Technical Field

[0001] This utility model relates to the field of precision testing technology for stamping presses, and in particular to a hydraulic system moving adjustment mechanism. Background Technology

[0002] Currently, in the field of precision testing of stamping presses, hydraulic cylinders are commonly used to support the press slide table, and the inspection work is completed by measuring the deformation of the press table.

[0003] However, this testing method has revealed many problems in actual operation. Due to the differences in the structure of press platforms of different specifications, the placement of the four hydraulic cylinders is also different. When carrying out testing, operators first need to spend a lot of time accurately marking the placement of each hydraulic cylinder. This process not only requires operators to have a high degree of concentration and professional skills to ensure the accuracy of the marking, but is also easily affected by human factors, such as marking errors or positional deviations, which in turn affect the reliability of subsequent test results. After marking, the hydraulic cylinders need to be hoisted to the designated position using an overhead crane. The operation of the overhead crane itself has a certain degree of complexity and risk. During the hoisting process, the hydraulic cylinders may shake or swing, increasing the difficulty of operation. At the same time, because the hydraulic cylinders are large and heavy, improper operation can easily lead to safety accidents, such as the hydraulic cylinders falling and injuring personnel or damaging equipment, posing a serious threat to the life safety of operators and the safety of company property. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a hydraulic system moving adjustment mechanism. The handwheel adjustment mechanism facilitates the movement of the slide by operators while ensuring personnel safety. Its mobility effectively resolves the contradiction between precise positioning and high speed in large-tonnage hydraulic systems, and the movement process is simple and convenient. Equipped with pointers, scales, and limit blocks, it prevents the slide from exceeding its travel range and causing collisions. The overall structure is simple and inexpensive, while simultaneously improving work efficiency and reducing costs.

[0005] This utility model proposes a hydraulic system moving adjustment mechanism, including a base plate, two Y-axis translation linkage slides (Y-axis is the left and right direction of the base plate), two sets of X-axis translation linkage slides arranged symmetrically (X-axis is the front and back direction of the base plate), three linkage drive mechanisms, and a hydraulic cylinder support.

[0006] Two Y-axis translation linkage slides are symmetrically arranged on the upper surface of the base plate, and the two Y-axis translation linkage slides can move in linkage along the left and right directions of the base plate. Each Y-axis translation linkage slide provides the left and right position change of the two hydraulic cylinders supported on it.

[0007] Two sets of X-axis translation linkage slide groups are respectively set on the upper surface of two Y-axis translation linkage slide groups, and each set of X-axis translation linkage slide groups can move in linkage along the front and rear direction of the Y-axis translation linkage slide group. Each set of X-axis translation linkage slide groups provides synchronous position changes of two hydraulic cylinders on the same side in the front and rear direction.

[0008] The hydraulic cylinder support seats are matched in number and are mounted on the upper surfaces of two sets of X-axis translation linkage slide groups;

[0009] A linkage drive mechanism is set on the base plate between two Y-axis translation linkage slides, and the linkage drive mechanism is connected to the pivot of each Y-axis translation linkage slide through a connecting rod, so as to enable the linkage drive mechanism to control the two Y-axis translation linkage slides to synchronously contract and translate inward or synchronously expand and translate outward. The synchronous contraction or expansion translation of the two Y-axis translation linkage slides causes the two sets of X-axis translation linkage slides and the other two linkage drive mechanisms set on them to synchronously contract or expand and translate.

[0010] The other two linkage drive mechanisms are respectively located at the left and right outer ends of the two Y-axis translation linkage slides. Each linkage drive mechanism is connected to the two X-axis translation linkage slides of each corresponding X-axis translation linkage slide group via a connecting rod. The two linkage drive mechanisms control the hydraulic cylinders on one side of the X-axis translation linkage slide group to adjust the press load position of the two hydraulic cylinders on one side in the front-back direction. The front-back position of the press load of the hydraulic cylinders in the left and right X-axis translation linkage slide groups can be adjusted to the same displacement or different displacement. Since the X-axis and Y-axis linkage translation platforms are used to complete the X-axis and Y-axis translation displacement adjustment of the four hydraulic cylinders, the placement accuracy deviation caused by the overhead crane hoisting the hydraulic cylinders to the designated position is eliminated, as well as the safety accidents that may occur when the hydraulic cylinders shake, swing, or even fall off during hoisting. This greatly improves the accuracy and speed of movement, avoids safety accidents that may occur during movement, and is easy to operate.

[0011] Two sets of slide rails are symmetrically arranged on the upper surface of the base plate along the length direction. Each set of slide rails includes three parallel Y-axis slide rails in the front and back direction. An X-axis guide slide rail is provided at the rear of the upper surface of the base plate between the two sets of slide rails.

[0012] Each Y-axis translation linkage slide is a rectangular plane. A strip-shaped protrusion extends horizontally outward from the middle of one of the long sides of this rectangular plane. A Y-axis guide rail is installed along the length of the upper surface of this strip-shaped protrusion, with one end extending to the upper surface of the rectangular plane structure. The lower surface of the Y-axis translation linkage slide is equipped with a corresponding number of two-section Y-axis sliders, matching the positions of the three Y-axis sliders in the slide rail assembly. These three two-section Y-axis sliders can slide left and right, engaging with the corresponding Y-axis sliders on the base plate. Five X-axis sliders are installed along the two long sides of the upper surface of the rectangular plane. The upper and lower ends of the Y-axis guide rails are rectangular... Each side of the rectangular plane is provided with a vertically corresponding X-axis slide rail. On the side of the rectangular plane away from the Y-axis guide slide rail, there are three X-axis slide rails. The upper X-axis slide rail of the three X-axis slide rails is symmetrically arranged with the upper X-axis slide rail of the Y-axis guide slide rail. The lower two X-axis slide rails of the three X-axis slide rails are aligned vertically with the lower X-axis slide rail of the Y-axis guide slide rail. There is a gap between the lower two X-axis slide rails of the three X-axis slide rails. The three X-axis slide rails are arranged along a straight line. The first connecting rod shaft is provided on the rectangular plane to the left of the gap between the lower two X-axis slide rails of the three X-axis slide rails.

[0013] Each X-axis translation linkage slide group includes two X-axis translation linkage slides with identical structures. Each X-axis translation linkage slide includes an X-axis slide mounting plate, four X-axis sliders, a second connecting rod shaft, and two hydraulic cylinder support seat positioning pins. The four X-axis sliders are symmetrically arranged on the lower surface of the X-axis slide mounting plate in pairs. The four X-axis sliders slide back and forth and are engaged with the five X-axis slide rails of the corresponding Y-axis translation linkage slide. The hydraulic cylinder support seats are mounted on the upper surface of the X-axis slide mounting plate and are horizontally limited and fixed by two hydraulic cylinder support seat positioning pins to prevent the hydraulic cylinder support seats from moving horizontally in the X or Y direction.

[0014] Each linkage drive mechanism includes a linkage slider and two linkages. The linkage sliders of the two linkage drive mechanisms slide left and right respectively on corresponding Y-axis guide rails. The adjacent ends of the two linkages of each linkage drive mechanism are axially connected to the upper surface of the linkage slider on the same side, and the other ends of the two linkages on the same side are rotatably connected to the second linkage shafts on the upper surface of the two X-axis slide mounting plates on the same side. The linkage slider of the third linkage drive mechanism slides back and forth on the X-axis guide rail of the base plate. The adjacent ends of the two linkages of the third linkage drive mechanism are axially connected to the upper surface of its linkage slider, and the other ends of the two linkages of the third linkage drive mechanism are rotatably connected to the first linkage shafts of the two Y-axis translation linkage slides. The gap between the lower two sections of the three X-axis slide rails in the translation linkage slide is designed to avoid obstructing the linkage of the linkage drive mechanism. The three linkage drive mechanisms have the same structure and dimensions, allowing for interchangeable installation and avoiding installation errors caused by size discrepancies. This also saves on the cost of replacing ball screws with different models, making installation simple and quick. The linkage drive mechanism is designed as a linkage slider and two linkage rods rotating together. The synchronous forward and backward displacement of the two X-axis translation linkage slides on the same side can be adjusted by directly pushing and pulling the linkage slider (or by pushing and pulling the push-pull rod connected to the linkage slider). The synchronous left and right displacement of the two Y-axis translation linkage slides can also be adjusted by directly pushing and pulling the linkage slider (or by pushing and pulling the push-pull rod connected to the linkage slider).

[0015] The base plate has four clearance holes corresponding to the stroke of each hydraulic cylinder support. These clearance holes are designed to allow space for the lower structure of the hydraulic cylinder support, providing travel clearance for the hydraulic cylinder support. Each Y-axis translational linkage slide has two first clearance U-shaped opening slots with right-end openings symmetrically arranged front and rear. Each first clearance U-shaped opening slot has a matching first support plate at its opening. The upper X-axis slide rail of the three X-axis slide rails is detachably fixed to the upper surface of the aligned Y-axis translational linkage slide and the front first support plate, thus limiting and fixing the upper X-axis slide rail in the Z-axis (vertical direction). The lower two X-axis slide rails are detachably fixed to the upper surface of the aligned Y-axis translational linkage slide and the rear first support plate, respectively, to limit and fix the lower X-axis slide rails in the Z-axis. The first connecting rod shaft is aligned and fixed to the upper surface of the rear first support plate. Each first support plate is engaged with a first horizontally placed U-shaped limiting pressure plate at the joint with the corresponding Y-axis translational linkage slide. The first horizontally placed U-shaped limiting pressure plate is screwed to the outer wall of the Y-axis translational linkage slide by horizontally arranged bolts to limit and fix each first support plate in the Y-axis (here, to the right) and Z-axis directions. The design of the plate and the first clearance U-shaped opening slot is to avoid the lower structure of the hydraulic cylinder support seat, providing travel clearance and limiting space for the hydraulic cylinder support seat, while also facilitating assembly; each X-axis slide mounting plate has a second clearance U-shaped opening slot with an opening on one long side in the middle, and the opening of the second clearance U-shaped opening slot is matched and accommodated with a second support plate. The second support plate and the corresponding X-axis slide mounting plate are engaged with a second horizontally placed U-shaped limiting pressure plate at each joint. The second horizontally placed U-shaped limiting pressure plate is screwed and fixed to the outer wall of the X-axis slide mounting plate by horizontally placed bolts, so as to ensure that each second... The support plate is fixed in the X-direction (forward direction in this case) and Z-direction. The design of the second support plate and the second clearance U-shaped opening groove is to avoid the lower structure of the hydraulic cylinder support seat, providing travel clearance and limiting space for the hydraulic cylinder support seat, and also facilitating assembly. The lower end of the support plane of the hydraulic cylinder support seat has a stepped shaft structure protruding downward. The diameter of the stepped shaft structure gradually decreases from top to bottom. The purpose of setting the stepped shaft structure is to increase the support strength of the upper end surface of the hydraulic cylinder support seat. At the same time, when the hydraulic cylinder is seated on the hydraulic cylinder support seat, it needs to be fixed by bolts. The stepped shaft structure can increase the bolt engagement strength at the bolt engagement.

[0016] The front and rear ends of the X-direction guide slide rail on the upper surface of the base plate are provided with first ball screw connecting rod support blocks; the left and right sides of the Y-direction guide slide rail on the upper surface of each Y-direction translation linkage slide are provided with second ball screw connecting rod support blocks.

[0017] Each linkage drive mechanism also includes a ball screw, a screw nut, two screw support bearings, and a handwheel. The screw nut is embedded and fixed in the middle of the upper end of the linkage slider. The ball screw is rolled and sleeved in the screw nut. The inner rings of the two screw support bearings are fixed to the two ends of the ball screw, respectively. The handwheel is fixed to one end of the ball screw by bolts. The two screw support bearings of one linkage drive mechanism are respectively aligned and fixed on the two first ball screw linkage support blocks of the base plate, and the handwheel is located outside the base plate. The two pairs of screw support bearings of the other two linkage drive mechanisms are respectively aligned and fixed on the two second ball screw linkage support blocks of each Y-axis translation linkage slide, and the handwheels of the other two linkage drive mechanisms are respectively located outside the Y-axis translation linkage slide.

[0018] On the upper surface of the base plate, the two sets of slide rails are equipped with Y-direction sliding rails on both sides of the Y-direction sliding rails. These Y-direction sliding linkage slides are designed to prevent them from moving left or right beyond the travel range of the slide rails. Each Y-direction sliding linkage slide is equipped with X-direction sliding plate mounting plate anti-detachment elastic stop blocks at the front, middle, and rear ends of the upper surface of the slide plate. These X-direction sliding plate mounting plates are designed to prevent them from moving forward or backward beyond the travel range of the slide rails.

[0019] A first length scale is engraved on the long side wall of one end of the base plate, corresponding to the middle position of each Y-axis translation linkage slide. A first centering pointer is set on the middle of the short side wall of each Y-axis translation linkage slide corresponding to the position of the first length scale. The first centering pointer is adjacent to the outside of the corresponding first length scale so that the first centering pointer accurately indicates the displacement in the Y-axis as the Y-axis translation linkage slide moves left and right. A second length scale is engraved on the middle of the front and rear sections of the outer side wall of one long side of each Y-axis translation linkage slide. A second centering pointer is set on the middle of the outer side wall of each X-axis slide mounting plate corresponding to the position of the second length scale. The second centering pointer is adjacent to the outside of the aligned second length scale so that the second centering pointer accurately indicates the displacement in the X-axis as the X-axis slide mounting plate moves back and forth.

[0020] The base plate is equipped with two pairs of hinged support legs on the left and right sides, which can be hinged and flipped 180 degrees. When a load-bearing test is required, the four support legs can be flipped to support the ground, preventing the base plate from directly contacting the ground dirt.

[0021] The upper surface of the base plate is equipped with a hinge limit hook corresponding to each flip support leg position. The hinge limit hook can be engaged and fixed with the flip support leg after it has been flipped up 180 degrees, which is used to support the entire base plate and prevent the bottom surface of the hydraulic cylinder support seat from contacting the ground and causing friction during the movement of the slide.

[0022] Each Y-axis translation linkage slide has an anti-reverse mounting protrusion at its front and rear ends on its upper surface. The straight-line distance between the two anti-reverse mounting protrusions and the right end of the Y-axis translation linkage slide is different for each Y-axis translation linkage slide. The two anti-reverse mounting protrusions of the same Y-axis translation linkage slide are set at different distances, which can quickly identify the corresponding X-axis slide mounting plate and avoid incorrect or reverse installation. On the long side of the two X-axis slide mounting plates on the same side away from the second avoidance U-shaped opening slot, there is an anti-reverse mounting missing slot. The position of the anti-reverse mounting missing slot of the two X-axis slide mounting plates on the same side corresponds to the position of the two anti-reverse mounting protrusions on the same side. The anti-reverse mounting protrusions can be matched and contacted in the anti-reverse mounting missing slots to prevent the X-axis slide mounting plates from being installed backwards.

[0061] Working principle

[0062] Adjust the X and Y positions of the hydraulic cylinder during testing.

[0063] See Figures 1-5 As shown, firstly, manually crank the handwheel 4.6 of the linkage drive mechanism 4 that controls the movement of the two Y-axis translation linkage slides 2, driving the ball screw 4.3 to rotate together, pushing the screw nut 4.4 to move axially along the ball screw 4.3; this causes the linkage slider 4.1 to move backward, and the two linkage rods 4.2 connected by pins pull the left and right Y-axis translation linkage slides 2 inward towards the center, adjusting the Y-axis coordinate of the hydraulic cylinder; after the Y-axis position is reached, manually crank the handwheels of the two linkage drive mechanisms 4 of the two sets of X-axis translation linkage slide groups 3, respectively, driving the two ball screws 4.3 to rotate, pushing the two screw nuts 4.4 to move axially along the ball screw 4.3; this causes the two linkage sliders 4.1 to move backward respectively, and each linkage slider 4.1, connected by pins, pulls the two X-axis slide mounting plates 3.1 on the same side to move towards the center, adjusting the X-axis coordinate of the hydraulic cylinder until the target position is reached.

[0064] like Figure 6 The image shows the initial position (worktable surface 5500×2800) of a hydraulic system moving adjustment mechanism on the worktable of a stamping press, with the hydraulic cylinder positioned according to the national standard GB / T29546-2013. The hydraulic system can directly apply load to this press at this position.

[0065] like Figure 7As shown, a hydraulic system moving adjustment mechanism is used on the worktable of a stamping press. The hydraulic cylinder is positioned at the target position (worktable surface 4600×2150) according to the national standard GB / T29546-2013. The slides are moved and adjusted by 150mm along the X and Y directions respectively. The press load can only be applied after the target position is reached. The handwheel is manually turned, the lead screw rotates, and the nut moves axially on the lead screw. The linkage slider connected to the nut drives the connecting rod, and the connecting rod pulls the two slides on both sides to move in the center. The operation is simple and convenient, which greatly improves the work efficiency of the workers.
