[0048] Figure 1 A schematic diagram of the steering gear assembly and fixing device according to one embodiment of this application is shown. (See also...) Figure 1 An embodiment of this application provides a steering gear disassembly and fixing device comprising: a base plate 100; a first flipping clamping mechanism 200, fixedly disposed on the base plate 100, for clamping the first end of the steering gear to be disassembled and flipping the steering gear to be disassembled to a limiting mechanism 300; a limiting mechanism 300, fixedly disposed on the base plate 100; and a second flipping clamping mechanism 400, for pressing the steering gear to be disassembled to the outer surface of the steering gear to be disassembled when the first flipping clamping mechanism 200 flips the steering gear to be disassembled to the limiting mechanism 300.

[0049] For example, the on-site lifting device is connected to the second end of the steering gear to be assembled, and the first end of the steering gear to be assembled is close to the steering gear assembly and fixing device provided in this embodiment. The on-site lifting device lifts the steering gear to be assembled above the first flipping clamping mechanism 200 in the steering gear assembly and fixing device, so that the first flipping clamping mechanism 200 can clamp the first end of the steering gear to be assembled after contacting it.

[0050] For example, after the first flipping clamping mechanism 200 clamps the first end of the steering gear to be packaged, without disassembling the lifting device, the steering gear to be packaged is tilted towards the limiting mechanism 300 by manual operation, and the steering gear to be packaged is flipped to the limiting mechanism 300. The limiting mechanism 300 is used to fix the outer surface of the first end and the second end of the steering gear to be packaged on the side close to the substrate 100, and the second flipping clamping mechanism 400 is used to fix the outer surface of the first end and the second end of the steering gear to be packaged on the side away from the substrate 100.

[0051] Optionally, the rigid structure of the steering gear assembly and fixing device provided in this embodiment is made of high-carbon steel and treated with tempering and quenching processes. The entire device is non-standard machined, resulting in high strength. The surfaces of the rigid structure are all rust-proofed, and all friction baffle components are made of Cr12 material with an HRC (Hardness Rockwell C) of 58-62. Each flip-up component is equipped with ball bearings to ensure the device's ability to return to its original position after flipping.

[0052] Optionally, the steering gear sub-assembly fixing device in this embodiment can sub-assemble steering gears of the following models: 3411010-53S, 3411010-2010, 3411010-14b-13c, 3411010-240, 3411010-46a, 3411010a50a-80a, 3411010-56s, ZF electro-hydraulic steering gear, and BS electro-hydraulic steering gear.

[0053] The steering gear sub-assembly and fixing device provided in this embodiment includes: a base plate 100; a first flipping clamping mechanism 200, fixedly disposed on the base plate 100, used to clamp the first end of the steering gear to be sub-assembled and flip the steering gear to be sub-assembled to the limiting mechanism 300; a limiting mechanism 300, fixedly disposed on the base plate 100; and a second flipping clamping mechanism 400, used to press the steering gear to be sub-assembled to the outer surface of the steering gear to be sub-assembled when the first flipping clamping mechanism 200 flips the steering gear to be sub-assembled to the limiting mechanism 300. In this embodiment, the first flipping clamping mechanism 200 fixed on the base plate 100 fixes the first end of the steering gear to be sub-assembled, and the second flipping clamping mechanism 400 and the limiting mechanism 300 fix the outer surface of the steering gear to be sub-assembled, avoiding the problem of poor stability caused by the clamping of traditional sub-assembly and fixing devices. The steering gear sub-assembly and fixing device in this embodiment can firmly fix the steering gear to be sub-assembled, improving the stability of the steering gear sub-assembly and fixing device.

[0054] In one embodiment, the contact surfaces of the first flipping clamping mechanism 200, the limiting mechanism 300, and the second flipping clamping mechanism 400 in the provided steering gear sub-assembly and fixing device with the steering gear to be sub-assembled are all provided with elastic material.

[0055] For example, the elastic material can be polyurethane or rubber.

[0056] In this embodiment, by providing an elastic material on the contact surface between the steering gear sub-assembly fixing device and the steering gear to be sub-assembled, wear on the steering gear to be sub-assembled is avoided during the fixing and assembly of the steering gear to be sub-assembled, and the friction between the steering gear to be sub-assembled and the steering gear sub-assembly fixing device is increased to prevent the steering gear to be sub-assembled from coming off, thereby improving the safety and reliability of the steering gear sub-assembly fixing device.

[0057] Figure 2 A schematic diagram of the structure of the first flipping clamping mechanism 200 in one embodiment of this application is shown. Figure 3 A schematic diagram of the second side of a mounting plate according to an embodiment of this application is shown. (In conjunction with...) Figure 2 and Figure 3 In one embodiment, the first flipping clamping mechanism 200 in the provided steering gear assembly and fixing device includes:

[0058] Mounting plate 210 is rotatably connected to base plate 100. A positioning disk 212 is fixedly provided on the first surface of mounting plate 210. An avoidance hole 214 is provided in the center of positioning disk 212. Pneumatic clamping module 220 is movably provided on the first surface of mounting plate 210. Pneumatic clamping cylinder 230 is connected to pneumatic clamping module 220 and is used to control the movement of pneumatic clamping module 220 on mounting plate 210.

[0059] The rotatable portion of the mounting plate 210 is connected to the base plate 100 via a fixing plate, which is fixedly connected to the base plate 100. The first surface of the mounting plate 210 faces the first end of the steering gear to be assembled. A positioning disc 212 can be fixedly positioned in the middle of the mounting plate 210. The positioning disc 212 has a recessed hole 214 at its center to accommodate the oil plug screw of the first end of the steering gear to be assembled. The diameter of the recessed hole 214 is larger than the diameter of the oil plug screw to accommodate oil plug screws with different head shapes. The positioning disc 212 is rotatably connected to the second surface of the mounting plate 210 via a pivot shaft.

[0060] Among them, the pneumatic clamping module 220 can move on the mounting plate 210 under the control of the pneumatic clamping cylinder 230, and can clamp steering gears of different sizes to be assembled.

[0061] In this embodiment, before fixing the steering gear to be assembled, the oil plug screw at the first end of the steering gear to be assembled is placed into the avoidance hole 214 in the first flip clamping mechanism 200, which can accurately position the steering gear to be assembled to a fixed position. The steering gear to be assembled is completely clamped by pneumatic clamping, which completely cancels the gap and sway between the steering gear to be assembled and the steering gear assembly fixing device.

[0062] In one embodiment, see further. Figure 2 and Figure 3 The pneumatic clamping module 220 in the provided steering gear sub-assembly and fixing device includes: a first moving positioning gripper 222 and a second moving positioning gripper 224, the first moving positioning gripper 222 and the second moving positioning gripper 224 being symmetrically arranged on both sides of the positioning plate 212.

[0063] In the relaxed state, the first movable positioning gripper 222 is located near the edge of the mounting plate 210 on the side of the first movable positioning gripper 222, and the second movable positioning gripper 224 is located near the edge of the mounting plate 210 on the side of the second movable positioning gripper 224. The distance between the first movable positioning gripper 222 and the second movable positioning gripper 224 is the greatest. After the oil plug screw at the first end of the steering gear to be assembled falls into the avoidance hole 214, there is a gap between the first movable positioning gripper 222, the second movable positioning gripper 224, and the outer surface of the steering gear to be assembled in the relaxed state. The gap distance varies depending on the product model of the steering gear to be assembled.

[0064] For example, the distance between the first moving positioning gripper 222 and the outer surface of the steering gear to be packaged can be 15mm, and the distance between the second moving positioning gripper 224 and the outer surface of the steering gear to be packaged can be 15mm.

[0065] For example, the pressure applied to the steering gear to be packaged by the first moving positioning gripper 222 and the second moving positioning gripper 224 in the clamping state can be 100 kg.

[0066] In one possible implementation, the first movable positioning gripper 222 is connected to the second surface of the mounting plate 210 via two guide sliders, and the structure of the second movable positioning gripper 224 is the same as that of the first movable positioning gripper 222. The steering gear sub-assembly and fixing device also includes a first pneumatic control button and a second pneumatic control button, both of which are connected to the pneumatic clamping cylinder 230. When the first pneumatic control button is pressed, the pneumatic clamping cylinder 230 controls the first movable positioning gripper 222 to move along the track corresponding to the guide slider, simultaneously clamping the first end of the steering gear to be sub-assembled with the second movable positioning gripper 224. When the second pneumatic control button is pressed, the pneumatic clamping cylinder 230 releases the control of the first movable positioning gripper 222 and the second movable positioning gripper 224, and the first movable positioning gripper 222 and the second movable positioning gripper 224 return to the relaxed state.

[0067] In this embodiment, the first movable positioning gripper 222 and the second movable positioning gripper 224, which are symmetrically arranged on both sides of the positioning disk 212, can fully clamp the first end of the steering gear to be assembled.

[0068] In one embodiment, the side of the first movable positioning gripper 222 in the provided steering gear assembly and fixing device facing the positioning disk 212 includes a first surface, a second surface, and a third surface; the first surface and the third surface are provided with elastic material.

[0069] The first and third surfaces are the contact surfaces between the first movable positioning gripper 222 and the steering gear to be assembled when clamped. The side lengths of the first and third surfaces vary depending on the size of the outer surface of the steering gear to be assembled. For example, the side lengths of the first and third surfaces can be 40mm to 60mm.

[0070] In one possible implementation, the structure of the second movable positioning gripper 224 is the same as that of the first movable positioning gripper 222. The first surface of the first movable positioning gripper 222 is parallel to the third surface of the second movable positioning gripper 224, and the third surface of the first movable positioning gripper 222 is parallel to the first surface of the second movable positioning gripper 224. In this way, the first movable positioning gripper 222 and the second movable positioning gripper 224 can simultaneously apply symmetrical pressure to the steering gear to be assembled, thereby fully clamping the steering gear to be assembled.

[0071] Continue reading Figure 1 In one embodiment, the second flipping clamping mechanism 400 in the provided steering gear sub-assembly fixing device includes: a pneumatic pressure plate 420, the surface of the pneumatic pressure plate 420 facing the steering gear to be sub-assembled is provided with an elastic material; and a pneumatic clamping cylinder 440, which is hinged to a first side of the pneumatic pressure plate 420 and is used to control the pneumatic pressure plate 420 to flip along the first side.

[0072] The pneumatic clamping cylinder 440 is hinged to the first side of the pneumatic pressure plate 420. When the pneumatic clamping cylinder 440 is in the relaxed state, the pneumatic pressure plate 420 is suspended. For example, when the pneumatic clamping cylinder 440 is in the relaxed state, the angle between the pneumatic pressure plate 420 and the pneumatic clamping cylinder 440 can be 180°. When the pneumatic clamping cylinder 440 controls the pneumatic pressure plate 420 to clamp the steering gear to be packaged, the pneumatic pressure plate 420 rotates along its first side towards the steering gear to be packaged until it contacts the outer surface of the steering gear to be packaged, and applies pressure to the outer surface of the steering gear to be packaged to clamp it. For example, the pressure of the pneumatic pressure plate 420 on the steering gear to be packaged can be 100 kg.

[0073] In one possible implementation, the steering gear sub-assembly and fixing device further includes a third pneumatic control button and a fourth pneumatic control button, both connected to the pneumatic clamping cylinder 440. Pressing the third pneumatic control button causes the pneumatic clamping cylinder 440 to control the pneumatic pressure plate 420 to flip along the first side, applying pressure to the outer surface of the steering gear to be sub-assembled. Pressing the fourth pneumatic control button uses the pneumatic clamping cylinder 440 to control the pneumatic pressure plate 420 to flip along the first side, releasing the pressure applied to the outer surface of the steering gear to be sub-assembled.

[0074] In this embodiment, the second flipping clamping mechanism 400 applies pressure to the outer surface of the steering gear to be assembled on the side away from the substrate 100 between the first end and the second end of the steering gear to be assembled, so as to further clamp the steering gear to be assembled and improve the stability of the steering gear assembly and fixing device.

[0075] Figure 4 This is a schematic diagram of the structure of the first gripper stop 322 in the gripper limiting module 320 of one embodiment. (See attached diagram) Figures 1 to 3 In one embodiment, the limiting mechanism 300 in the provided steering gear sub-assembly and fixing device includes: a gripper limiting module 320, used to restrict the movement of the first flipping clamping mechanism 200 when the steering gear to be sub-assembled is flipped to the limiting mechanism 300; the gripper limiting module 320 includes a first gripper baffle 322 and a second gripper baffle 324, the first gripper baffle 322 being dynamically engaged with the first movable positioning gripper 222; the second gripper baffle 324 being dynamically engaged with the second movable positioning gripper 224; a contour limiting module 340, used to restrict the displacement of the steering gear to be sub-assembled when it is flipped to the limiting mechanism 300; and a bottom limiting module 360, used to support the surface of the steering gear to be sub-assembled facing the bottom limiting module 360.

[0076] During the process of the steering gear to be assembled being flipped to the limiting mechanism 300, the first gripper wall 322 engages with the first movable positioning gripper 222, and the second gripper wall 324 engages with the second movable positioning gripper 224, so as to counteract the lateral force of the steering gear to be assembled during the flipping process, so that the steering gear to be assembled can be more stably fixed in the steering gear assembly fixing device.

[0077] Continue reading Figure 4 In one embodiment, the first gripper wall 322 and the second gripper wall 324 in the provided steering gear assembly and fixing device both include a wall replacement block 3222 with adjustable thickness.

[0078] In the first gripper wall 322, the retaining block 3222 is fixedly mounted on the first wall frame 3226 by clamping screws 3224. The first wall frame 3226 is fixedly mounted on the base plate 100. The thickness of the retaining block 3222 is adjustable. The structure of the second gripper wall 324 is completely identical to that of the first gripper wall 322.

[0079] In one possible implementation, the clamping screw 3224 fixes the retaining wall block 3222 from the first side and the retaining wall block 3222 from the second side. The distance between the first gripper retaining wall 322 and the second gripper retaining wall 324 is different. The distance between the first gripper retaining wall 322 and the second gripper retaining wall 324 is adjusted by adjusting the clamping screw 3224 to fix the retaining wall block 3222.

[0080] In this embodiment, retaining wall blocks 3222 of different thicknesses are provided, so that the distance between the first gripper retaining wall 322 and the second gripper retaining wall 324 can be adjusted according to the diameter of the first end of the steering gear to be assembled, thereby expanding the application range of the steering gear assembly and fixing device.

[0081] Figure 5 This is a schematic diagram of the contouring limiting module 340 and the bottom limiting module 360 ​​in one embodiment. In one embodiment, the contouring limiting module 340 includes a fixed contouring part and an adjustable contouring part. The fixed contouring part is fixed on the base plate 100 and matches the outer surface of different models of steering gears to be assembled. The adjustable contouring part is fixed on the base plate 100, and the side of the adjustable contouring part facing the steering gear to be assembled is provided with a shim of elastic material. The distance between the adjustable contouring part and the fixed contouring part can be adjusted by adjusting the screw and the number of shims to tightly fix the different models of steering gears to be assembled.

[0082] Continue reading Figure 5In one embodiment, the bottom limiting module 360 ​​in the provided steering gear sub-assembly fixing device includes: a steering gear lower limiting support block 362, which includes a plurality of stacked sub-support blocks and a fixing shaft for fixing the sub-support blocks; and a lower limiting conforming support block 364, which matches the shape of the second end of the steering gear to be sub-assembled.

[0083] For example, the steering gear lower limit support block 362 includes two stacked sub-support blocks. When disassembling different models of steering gears, the number of sub-support blocks can be manually adjusted without the need for screws.

[0084] In this embodiment, after the steering gear to be assembled is flipped to the limiting mechanism 300, the contour limiting module 340 and the bottom limiting module 360 ​​fix the steering gear to be assembled from multiple positions, so that the steering gear to be assembled remains stable during the subsequent assembly process.

[0085] In one embodiment, the provided steering gear assembly and fixing device further includes: a limiting swing arm 500, disposed on one side of the first flipping clamping mechanism; and a swing arm support block 600, used to support the limiting swing arm 500 when it is folded down.

[0086] Among them, the limit swing arm 500 is a non-powered drive structure, made of high carbon steel with quenching treatment, and has tension springs installed on the side, which can move stably and avoid sudden falling and injuring people.

[0087] In one possible implementation, after the steering gear to be sub-assembled is completed, the control limit arm 500 is lowered onto the arm support block 600, and then the fourth pneumatic control button is pressed. The pneumatic pressure plate 420 is flipped along the first side by the pneumatic clamping cylinder 440 to release the pressure applied to the outer surface of the steering gear to be sub-assembled.

[0088] In one possible implementation, after the second flip clamping mechanism 400 releases the pressure, the steering gear to be sub-assembled is manually lifted upwards using a field lifting device. At the same time, the first flip clamping mechanism 200 controls the steering gear to be sub-assembled to flip and stand upright. Then, the second pneumatic control button is pressed to restore the first moving positioning jaw 222 and the second moving positioning jaw 224 to the relaxed state. The field lifting device then removes the steering gear to be sub-assembled from the steering gear sub-assembly and fixing device, completing the current sub-assembly operation.

[0089] In one possible implementation, the steering gear sub-assembly and fixing device further includes a sub-assembly platform. The base plate 100 is fixedly connected to the sub-assembly platform, which has a three-door design. Two sets of steering gear sub-assembly and fixing devices can be installed on the sub-assembly platform. The first, second, third, and fourth air control buttons of the steering gear sub-assembly and fixing device are installed on the side of the sub-assembly platform. The base plate 100 is fixed to the sub-assembly platform by screws. The first and second air control buttons are connected to the pneumatic clamping cylinder 230 through the first air passage. The third and fourth air control buttons are connected to the pneumatic pressing cylinder 440 through the second air passage. The first and second air passages are located below the platform surface of the sub-assembly platform. The platform surface of the sub-assembly platform is a 10mm thick steel plate, and a 10mm thick polyurethane layer is laid on the steel plate. The bottom of the sub-assembly platform is fixed to the ground by four anchor bolts.
