[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A tilting heavy-duty precision translation mechanism, combined with Figures 1-17 As shown, it includes: a lifting slide body 7, a translation slide body 6 and a translation drive mechanism, wherein the translation drive mechanism drives the translation slide body 6 to move horizontally along the lifting slide body 7; The lifting slide body 7 is provided with a first guide rail mounting surface 71 and a second guide rail mounting surface 72 that are arranged opposite to each other. The first guide rail mounting surface 71 and the second guide rail mounting surface 72 are arranged vertically. The lifting slide body 7 is provided with a horizontal third guide rail mounting surface 73, which is located between the first guide rail mounting surface 71 and the second guide rail mounting surface 72. The translation slide body 6 includes: a vertical mounting part 61, a horizontal connecting part 62, and a vertical anti-tilt part 63. The vertical mounting part 61 is located on the side of the first guide rail mounting surface 71 away from the second guide rail mounting surface 72. The vertical anti-tilt part 63 is located on the side of the second guide rail mounting surface 72 away from the first guide rail mounting surface 71. The horizontal connecting part 62 is located above the third guide rail mounting surface 73. The top ends of the horizontal connecting part 62 are fixedly connected to the top ends of the vertical mounting part 61 and the vertical anti-tilt part 63. A first linear guide rail 64 is provided between the vertical mounting part 61 and the first guide rail mounting surface 71; a third linear guide rail 66 is provided between the horizontal connecting part 62 and the third guide rail mounting surface 73; and a second linear guide rail 65 is provided between the vertical anti-tilt part 63 and the second guide rail mounting surface 72. This application improves anti-tilt capability by dividing the translation slide body 6 into three parts: a vertical mounting part 61, a horizontal connecting part 62, and a vertical anti-tilt part 63, and by providing three mounting surfaces—the first guide rail mounting surface 71, the second guide rail mounting surface 72, and the third guide rail mounting surface 73—on the lifting slide body 7. This creates a semi-enclosed frame layout.

[0020] Specifically, the layout of the first guide rail mounting surface 71, the second guide rail mounting surface 72, and the third guide rail mounting surface 73 forms a hooked shape. To reduce the load on individual guide sliders in a linear guide pair, each linear guide pair may contain three or more guide sliders. The spacing between the first linear guide 64, the second linear guide 65, and the third linear guide 66 is relatively large, especially the span between the first linear guide 64 and the third linear guide 66, which is beneficial to improving the overturning load capacity of the translation slide body 6.

[0021] Preferably, the lifting slide body 7 includes: two slide column 74, a slide crossbeam 75 fixed to the top of the two slide column 74, and an anti-tilt platform 76 fixed to the top of the slide crossbeam 75. A first guide rail mounting surface 71 is located on the front side of the slide crossbeam 75, and a second guide rail mounting surface 72 and a third guide rail mounting surface 73 are located on the anti-tilt platform 76. The second guide rail mounting surface 72 is located between the front and rear sides of the slide crossbeam 75, and the vertical anti-tilt part 63 is located between the second guide rail mounting surface 72 and the rear side of the slide crossbeam 75. The translation slide body 6 of this application is located in front of the rear side of the slide crossbeam 75, which avoids interfering with the lifting movement of the lifting slide body 7. This is because if the translation slide body 6 is provided with a frame structure that fully surrounds the slide crossbeam 75, causing the translation slide body 6 to protrude from the rear side of the slide crossbeam 75, the lifting slide body 7 must make way for the position of the translation slide body 6 to achieve a larger range of lifting stroke. This causes the drive and guide structures of the lifting slide body 7 to extend forward, reducing the structural rigidity of the lifting slide body 7 and consequently decreasing its load-bearing capacity and motion accuracy. Simultaneously, since the translation slide body 6 completely surrounds the slide beam 75 of the lifting slide body 7, the length of the slide beam 75 must be increased to achieve a wider translation range, meaning the distance between the two slide columns 74 needs to be increased. This is detrimental to improving the rigidity of the lifting slide body 7; furthermore, the increased width of the lifting slide body 7 makes it unsuitable for engineering equipment operating in confined spaces.

[0022] Specifically, the two slide column 74 and the slide beam 75 are an integral structure, which can be formed by casting or welding. The anti-tilt platform 76 adopts a spatial stiffener design and is fixed to the top of the slide beam 75 by welding. The lifting slide body 7 and the translation slide body 6 are both integral casting or welding structures, and are subjected to stress-relief annealing treatment to ensure the stability of dimensional accuracy.

[0023] The front side of the slide beam 75 is designed with a clearance groove for the installation of various components. Below the clearance groove, a first guide rail mounting groove is formed on the front side of the slide beam 75. Above the first guide rail mounting groove, a first guide rail clamping block mounting groove is formed. The lower wall of the first guide rail clamping block mounting groove serves as a positioning stop. The bottom surface of the first guide rail mounting groove is the first guide rail mounting surface 71. The first linear guide rail 64 abuts against the lower wall of the first guide rail mounting groove for positioning and is fixed to the first guide rail mounting surface 71 with screws. Several first guide rail clamping blocks 641 are fixed to the first guide rail clamping block mounting groove with screws. The first guide rail clamping blocks 641 and the upper wall of the first guide rail clamping block mounting groove are engaged with an inclined surface, thereby pressing the upper side of the first linear guide rail 64.

[0024] The rear side of the anti-tilt platform 76 is provided with a second guide rail mounting groove, and the lower groove wall of the second guide rail pressure block mounting groove serves as a positioning stop. The second guide rail mounting groove extends to the top surface of the anti-tilt platform 76, and the bottom surface of the second guide rail mounting groove is the second guide rail mounting surface 72. The second linear guide rail 65 abuts against the lower groove wall of the second guide rail mounting groove for positioning and is fixed to the second guide rail mounting surface 72 with screws. Several second guide rail pressure blocks 651 are fixed to the top edge of the anti-tilt platform 76 with screws. One end of the second guide rail pressure block 651 presses against the top surface of the anti-tilt platform 76, and the other end extends out of the top edge of the anti-tilt platform 76 and presses against the upper side of the second linear guide rail 65.

[0025] The top surface of the anti-tilt platform 76 is provided with a third guide rail mounting groove, and the front groove wall of the third guide rail pressure block mounting groove serves as a positioning stop. The upper part of the third guide rail mounting groove is provided with a third guide rail pressure block mounting groove, and the bottom surface of the third guide rail mounting groove is the third guide rail mounting surface 73. The third linear guide rail 66 abuts against the front groove wall of the third guide rail mounting groove for positioning and is fixed to the third guide rail mounting surface 73 by screws. Several third guide rail pressure blocks 661 are fixed in the third guide rail pressure block mounting groove by screws. The third guide rail pressure blocks 661 and the rear groove wall of the third guide rail pressure block mounting groove are engaged by a bevel, thereby pressing the rear side of the third linear guide rail 66.

[0026] The first guide rail mounting groove, the second guide rail mounting groove, and the third guide rail mounting groove are machined using high-precision machining methods, thereby ensuring that the first guide rail mounting surface 71, the second guide rail mounting surface 72, the third guide rail mounting surface 73, and several positioning stops meet strict requirements for flatness, parallelism, perpendicularity, and other geometric tolerances.

[0027] The arrangement of the first linear guide rail 64, the second linear guide rail 65, and the third linear guide rail 66 in this application allows the first linear guide rail 64 to extend to the position of the slide table crossbeam 75 corresponding to the slide table column 74, thereby allowing the vertical anti-tilting part 63 to move closer to the end of the slide table crossbeam 75, which in turn helps to increase the translational stroke.

[0028] Preferably, the translation drive mechanism includes: a translation rack 671, a translation gear 672, and a translation motor 673. The translation rack 671 is fixed on the slide beam 75, the translation motor 673 is mounted on the vertical mounting part 61, the translation gear 672 meshes with the translation rack 671, and the translation motor 673 drives the translation gear 672 to rotate.

[0029] Specifically, the translation rack 671 is fixed above the relief groove by screws, extends into the relief groove, and a stepped structure is also provided on the slide beam 75 to position the translation rack 671. The translation motor 673 drives the translation gear 672 to rotate, which in turn causes the translation gear 672 to roll along the translation rack 671, thereby driving the vertical mounting part 61 to move horizontally. The translation rack 671 uses helical teeth, and the translation motor 673 is a servo motor with an internal brake and precision rotary encoder.

[0030] Preferably, the translation rack 671 is located above the first linear guide rail 64. A motor mounting countersunk hole is provided on the vertical mounting part 61. The translation motor 673 passes through the motor mounting countersunk hole and connects to the translation gear 672. The translation motor 673 is connected to the vertical mounting part 61 via an adjusting component. By positioning the translation rack 671 above the first linear guide rail 64, the drive structure is positioned in the middle of the vertical mounting part 61. This allows the first linear guide rail 64 and the second linear guide rail 65 to be located on either side of the translation rack 671, encompassing the action points of the translation gear 672 and the translation rack 671. This provides overall structural rigidity and facilitates the precise, smooth, and reliable movement of the translation gear 672. Meanwhile, the first linear guide 64 is located at the lowest position near the vertical mounting part 61. When the translation slide body 6 has a tendency to tilt forward, the first linear guide 64, as a fulcrum, can reduce the lever arm of the load, so that the lever arm of the support force provided by the third linear guide 66 to the vertical anti-tilting part 63 is at its maximum, thereby reducing the magnitude of the support force of the third linear guide 66, which is beneficial to improving the anti-tilting capability.

[0031] Specifically, the vertical mounting part 61 adopts a box-shaped rib structure, with a rectangular opening in the middle. The edge of the steel plate on the side facing the slide beam 75 extends into the rectangular opening, forming the mounting position for the adjustment component. The rectangular opening and the steel plate together form a countersunk hole for motor mounting, and two rows of threaded holes are provided on the edge of the steel plate on one side of the slide beam 75.

[0032] Preferably, the adjusting component can achieve stepless adjustment of the backlash of the translation gear 672 and the translation rack 671. The adjusting components include: a translation motor mounting plate 6741, an upper adjusting seat 6742, an upper adjusting bolt 6743, a lower adjusting seat 6744, and a lower adjusting bolt 6745; the translation motor mounting plate 6741 is fixedly connected to the motor mounting countersunk hole through an elongated hole and screws, the elongated hole being set vertically; the upper adjusting seat 6742 is fixedly mounted on the translation motor mounting plate 6741, the upper adjusting bolt 6743 is threadedly connected to the upper adjusting seat 6742 and abuts against the upper wall of the motor mounting countersunk hole; the lower adjusting seat 6744 is fixedly mounted on the translation motor mounting plate 6741 and located below the upper adjusting seat 6742, the lower adjusting bolt 6745 is threadedly connected to the lower adjusting seat 6744 and abuts against the lower wall of the motor mounting countersunk hole; the translation motor 673 is mounted on the translation motor mounting plate 6741 and located between the upper adjusting seat 6742 and the lower adjusting seat 6744.

[0033] Specifically, the translation motor mounting plate 6741 has two rows of vertical elongated holes on both sides of its edge. These elongated holes correspond one-to-one with the threaded holes on the steel plate. After the screws pass through the elongated holes and are screwed into the threaded holes, the translation motor mounting plate 6741 is fixed to the steel plate. By loosening the screws, the vertical position of the translation motor mounting plate 6741 can be adjusted, thereby adjusting the gap between the translation gear 672 and the translation rack 671.

[0034] The upper adjusting seat 6742 includes an upper adjusting seat plate and reinforcing ribs, and is fixed to the upper end of the translation motor mounting plate 6741 by welding. Two threaded sleeves are welded to the lower surface of the upper adjusting seat plate. The upper adjusting seat plate is provided with two sets of upper adjusting bolts 6743, located at both ends of the upper adjusting seat plate. The upper adjusting bolts 6743 are screwed into the threaded sleeves. Upper adjusting bolt locking nuts are also installed on the upper adjusting bolts 6743, located on the upper surface of the upper adjusting seat plate. By tightening the upper adjusting bolt locking nuts and having them abut against the upper surface of the upper adjusting seat plate, the position of the upper adjusting bolts 6743 can be locked.

[0035] The lower adjusting seat 6744 includes a lower adjusting seat plate and reinforcing ribs, and is fixed to the lower end of the translation motor mounting plate 6741 by welding. Two threaded sleeves are welded to the upper surface of the lower adjusting seat plate. The lower adjusting seat plate is provided with two sets of lower adjusting bolts 6745, located at both ends of the lower adjusting seat plate and corresponding to the upper adjusting bolts 6743. The lower adjusting bolts 6745 are screwed into the threaded sleeves. A lower adjusting bolt locking nut is also installed on the lower adjusting bolt 6745, located on the lower surface of the lower adjusting seat plate. By tightening the lower adjusting bolt locking nut and having it abut against the lower surface of the lower adjusting seat plate, the position of the lower adjusting bolt 6745 can be locked.

[0036] When adjusting the vertical position of the translation motor mounting plate 6741, loosen the upper adjusting bolt lock nut, then loosen the upper adjusting bolt 6743, causing the upper adjusting bolt 6743 to abut against the upper wall of the motor mounting countersunk hole, thereby pushing the translation motor mounting plate 6741 downwards; simultaneously, loosen the lower adjusting bolt lock nut, then tighten the lower adjusting bolt 6745, pulling the translation motor mounting plate 6741 downwards; the two actions work together to achieve precise downward movement of the translation motor mounting plate 6741. When tightening the upper adjusting bolt 6743 and loosening the lower adjusting bolt 6745, the translation motor mounting plate 6741 can be precisely moved upwards. After the position is adjusted, lock the upper and lower adjusting bolt lock nuts to ensure that the position of the translation motor mounting plate 6741 remains unchanged.

[0037] The translation drive mechanism also includes a reducer. A clearance hole is provided on the translation motor mounting plate 6741. The translation motor 673 is mounted on the translation motor mounting plate 6741 through the reducer. The output shaft of the reducer passes through the clearance hole and connects to the translation gear 672.

[0038] Preferably, the translation gear 672 is keyed to the output shaft of the reducer (if no reducer is provided, the translation gear 672 is directly keyed to the output shaft of the translation motor 673). The output shaft end is threaded with a coaxial shaft end bolt 6751. The shaft end bolt 6751 presses the gear cover 6752 onto the translation gear 672 to limit the axial displacement of the translation gear 672. The shaft end bolt 6751 is fitted with a bolt anti-loosening plate 6753, which fits with the profile of the shaft end bolt 6751. The end face of the translation gear 672 is provided with multiple end face threaded holes in a ring array. The bolt anti-loosening plate 6753 is fixed to the translation gear 672 by anti-loosening bolts 6754 and end face threaded holes.

[0039] Specifically, the shaft end bolt 6751 can be adjusted using shims to ensure the tightness of the gear cover 6752. After aligning the through hole on the bolt anti-loosening plate 6753 with the nearest end face threaded hole, the anti-loosening bolt 6754 is screwed in. The bolt anti-loosening plate 6753 is fixed to the translation gear 672 by the two anti-loosening bolts 6754. The bolt anti-loosening plate 6753 rotates synchronously with the translation gear 672. Because the anti-loosening bolt 6754 and the translation gear 672 are not coaxial, the anti-loosening bolt 6754 will not loosen with rotation, ensuring that the bolt anti-loosening plate 6753 does not rotate relative to the translation gear 672. The bolt anti-loosening plate 6753 has a hexagonal hole in the middle that mates with the hexagonal head of the shaft end bolt 6751, thereby restricting the rotation of the shaft end bolt 6751 and effectively preventing the shaft end bolt 6751 from loosening or falling off.

[0040] Preferably, the device further includes an extreme position detection component, which includes: a first limit switch 681, a first sensing iron 682, a second limit switch 683, and a second sensing iron 684. The first limit switch 681 and the second limit switch 683 are located on the side of the slide beam 75 facing the vertical mounting portion 61, and are spaced apart along the translation direction. The first sensing iron 682 and the second sensing iron 684 are located on the side of the vertical mounting portion 61 facing the slide beam 75. The first sensing iron 682 moves forward along the translation direction to the first limit switch 681 and triggers a signal, and the second sensing iron 684 moves backward along the translation direction to the second limit switch 683 and triggers a signal.

[0041] Specifically, the first sensing iron 682 and the second sensing iron 684 are fixedly connected and fixed to the two edges of the inner side of the vertical mounting part 61 by screws. The first limit switch 681 and the second limit switch 683 are respectively fixedly connected and fixed to the slide beam 75 near both ends by screws. When the vertical mounting part 61 slides left and right, the cooperation of the first limit switch 681 and the first sensing iron 682, and the cooperation of the second limit switch 683 and the second sensing iron 684, can realize the signal detection of the limit position in the two sliding directions, so as to feed back to the electronic control system to determine that the translation slide body 6 has moved to the limit position, thereby obtaining the actual movement range of the translation slide body 6.

[0042] Preferably, the slide beam 75 is further provided with a first mechanical stop 685 and a second mechanical stop 686, which are spaced apart along the translational direction. The vertical mounting part 61 is provided with a first buffer pad 687 and a second buffer pad 688. The first buffer pad 687 moves forward along the translational direction to abut against the first mechanical stop 685 for limiting its position, and the second buffer pad 688 moves backward along the translational direction to abut against the second mechanical stop 686 for limiting its position. The first buffer pad 687 and the second buffer pad 688 are made of materials such as polyurethane rubber. The cooperation of the first mechanical stop 685 and the first buffer pad 687, and the cooperation of the second mechanical stop 686 and the second buffer pad 688, can achieve mechanical limiting and prevent the slider from falling off the track. The range of motion determined by the first mechanical stop 685 and the second mechanical stop 686 is greater than the actual range of motion determined by the limit position detection component.
