[0037] Example 1

[0038] Combination Figures 1 to 4 As shown, the utility model provides a guiding mechanism, which includes: a movable beam 10, which is provided with a movable beam groove 110; a guide seat 20, which includes a movable beam mounting end 210, and the movable beam mounting end 210 is connected to the movable beam groove 110 through a compensation mechanism; wherein, the compensation mechanism includes a fixed wedge 310 and a sliding wedge 320, and the inclinations of the contact surfaces of the fixed wedge 310 and the sliding wedge 320 are the same.

[0039] The present application abandons the prior art method of adding gaskets to supplement the gap, and innovatively uses a fixed bevel wedge 310 and a sliding bevel wedge 320 to compress and position between the guide seat 20 and the movable beam 10; after deformation occurs during long-term use, the gap can be compensated by adjusting the fixed bevel wedge 310 and the sliding bevel wedge 320, thereby achieving accurate positioning and improving the matching accuracy.

[0040] In this embodiment, the movable beam mounting end 210 is provided with a positioning surface 211 and an assembly surface 212, and the assembly surface 212 is provided with an assembly recess 2121; the fixed wedge 310 is fixed in the assembly recess 2121. Taking the example that the positioning surface 211 is located at the lower end surface of the movable beam mounting end 210 and the assembly surface 212 is located at the upper end surface of the movable beam mounting end 210 as an example for specific description, the movable beam mounting end 210 of the guide seat 20 is placed in the movable beam groove 110, and after the positioning surface 211 is closely attached to the lower end surface of the movable beam groove 110, the fixed wedge 310 is assembled on the assembly recess 2121 and fixed in the assembly recess 2121; then, the sliding wedge 320 is placed on the fixed wedge 310, and the lower side surface of the sliding wedge 320 is in contact with the upper side surface of the fixed wedge 310 to form a contact surface. Use the clamping screw 330 to install and connect the sliding wedge 320 to the movable beam groove 110, tap the movable beam mounting end 210, so that the left and right end faces of the movable beam mounting end 210 are tightly fitted with the movable beam groove 110, and use a feeler gauge to check whether the gap between the movable beam mounting end 210 and the movable beam groove 110 meets the requirements. If the requirements are met, tighten the clamping screw 330 to the specified torque to complete the positioning; finally, install the fixing screw 213 into the mounting hole of the movable beam mounting end 210 itself, and tighten it to the specified torque to achieve the fixation of the guide seat 20 and the movable beam 10.

[0041] It should be noted that, since the inclinations of the contact surfaces of the fixed bevel wedge 310 and the sliding bevel wedge 320 are the same, by changing the position of the sliding bevel wedge 320 relative to the fixed bevel wedge 310, it is possible to compensate for the gap caused by deformation, achieve accurate positioning, and improve matching accuracy. Compared with the prior art method of adding gaskets, the present application can shorten the operation time, and the compensation gap is highly accurate and controllable, and there is no need to select the corresponding gasket thickness and quantity based on the actual gap width.

[0042] In other embodiments, the positioning surface 211 may also be arranged on the upper end surface of the movable beam mounting end 210, and the assembly surface 212 may be arranged on the lower end surface of the movable beam mounting end 210. However, the method of arranging the positioning surface 211 on the lower end surface of the movable beam mounting end 210 and the assembly surface 212 on the upper end surface of the movable beam mounting end 210 can facilitate the operator to perform assembly and adjustment.

[0043] In this embodiment, the guide mechanism further includes a guide column 40; the guide seat 20 further includes a guide column mounting end 220, and the guide column mounting end 220 is sleeved on the guide column 40; a guide sleeve 50 is provided between the guide column mounting end 220 and the guide column 40. In this embodiment, the guide sleeve 50 is used to prevent the guide column mounting end 220 from directly contacting the guide column 40, thereby preventing the guide column 40 or the guide seat 20 from being damaged.

[0044] Preferably, the guide sleeve 50 is made of wear-resistant material.

[0045] Furthermore, the guide column mounting end 220 is provided with an oil inlet 221 and an oil outlet 222; the guide sleeve 50 is provided with an oil groove, which is connected to the oil inlet 221 and the oil outlet 222. Lubricating oil is added to the oil groove via the oil inlet 221, so that an oil film can be formed between the guide sleeve 50 and the guide column mounting end 220 of the guide seat 20, thereby reducing the wear of the guide sleeve 50.

[0046] The sparse oil circuit caused by the small clearance between the guide sleeve 50 and the guide column 40 (caused by design) will make it difficult to form a local oil film; further, the oil groove includes a first oil circuit 510 and a second oil circuit 520, and the first oil circuit 510 and the second oil circuit 520 are arranged to be staggered with each other and form at least one intersection, so that the surface of the guide sleeve 50 can be divided into multiple areas by using the first oil circuit 510 and the second oil circuit 520, so that the guide sleeve 50 and the guide column mounting end 220 of the guide seat 20 can be fully covered with an oil film, thereby reducing the wear of the guide sleeve 50 and increasing the service life.

[0047] Preferably, the surface of the guide sleeve 50 is provided with a plurality of the first oil circuits 510 and a plurality of the second oil circuits 520, wherein the plurality of the first oil circuits 510 are first spiral grooves arranged along the axial direction of the guide sleeve 50, and the plurality of the second oil circuits 520 are second spiral grooves arranged along the axial direction of the guide sleeve 50, and the spiral directions of the first spiral grooves and the second spiral grooves are arranged in opposite directions and are staggered with each other to form a plurality of intersections, dividing the surface of the guide sleeve 50 into more areas, so that the guide sleeve 50 and the guide column mounting end 220 of the guide seat 20 can be fully covered with an oil film.

[0048] Furthermore, the shape of the area is rhombus and triangle.

[0049] In this embodiment, a positioning side 223 is provided on one side of the guide column mounting end 220, and an insertion side 224 is provided on the other side; the positioning side 223 is abutted against the guide sleeve 50; the guide mechanism also includes a pressure cover 60 sleeved on the guide column 40, the pressure cover 60 includes a main body 610 and an insertion portion 620, the insertion portion 620 is inserted into the insertion side 224, and is located between the guide column 40 and the guide column mounting end 220.

[0050] Taking the example that the positioning side 223 is located at the lower end of the guide column mounting end 220 and the insertion side 224 is located at the upper end of the guide column mounting end 220 as an example, the guide sleeve 50 is placed between the guide column mounting end 220 and the guide column 40, the gap direction is aligned according to the requirements of the drawing, and the positioning side 223 is used for support; then the auxiliary tooling is inserted into the gap so that the outer circle of the guide sleeve 50 fits the inner circle of the guide column mounting end 220, and then the pressure cover 60 is placed on. The insertion portion 620 of the pressure cover 60 is inserted into the insertion side 224 and is located between the guide column 40 and the guide column mounting end 220. The insertion portion 620 is fitted with the guide sleeve 50, and the main body 610 is fixed to the guide column mounting end 220 by means of screws, so that only one side of the pressure cover 60 needs to be installed to complete the fixation of the guide sleeve 50. This embodiment is easy to assemble and disassemble and saves the number of parts, and the positioning side 223 can determine the positioning reference by processing.

[0051] In other embodiments, the positioning side 223 may also be disposed at the upper end of the guide post mounting end 220, and the insertion side 224 may also be disposed at the lower end of the guide post mounting end 220. However, the method of disposing the positioning side 223 at the lower end surface of the guide post mounting end 220 and the insertion side 224 at the upper end surface of the guide post mounting end 220 can facilitate the operator to perform assembly and adjustment.

[0052] Preferably, the pressure cover 60 and the positioning side 223 are also provided with a sealing ring 601 and a dust ring 602, and the sealing ring 601 and the dust ring 602 are sleeved on the guide column 40 to prevent the leakage of lubricating oil at the guide sleeve 50 and prevent external dust from entering the guide sleeve 50.

[0053] Furthermore, a rubber pad 70 is provided between the main body 610 and the guide column mounting end 220 to prevent the main body 610 from directly contacting the guide seat 20. In addition, the pressing force of the gland 60 can be designed by adjusting the tolerance design and the selection of the rubber pad 70 and the screw.

[0054] Due to the abnormal deformation of the fixing seat caused by the frame structure, the strong connection causes the guide column 40 to be severely bent, which increases the local stress of the guide sleeve 50, causing the guide sleeve 50 to be severely deformed and reducing its service life. To solve the above problems, in one embodiment, the guide column 40 includes a main section 410 and two connecting sections 420, the two connecting sections 420 are respectively located at the two ends of the main section 410, and the two connecting sections are narrowed relative to the main section 410.

[0055] Specifically, when the two connecting sections are respectively fixed to the fixing seats 80 located at the upper and lower ends of the guide column 40, the freedom of the guide column 40 except the vertical direction is constrained. Because the deformation of the frame will cause the guide column 40 to bend, and a slight initial gap can generate a margin for deformation, and because the connecting section is narrowed and short, and the gap with the shaft shoulder is far, the bending amplitude becomes smaller, reducing the influence of stress concentration on the guide sleeve 50.

[0056] Furthermore, an air avoidance groove 421 is provided on the outer peripheral side of the two connecting sections 420, which reduces the contact area between the connecting section 420 and the fixing seat, and is not fixed in the vertical direction, thereby greatly reducing the adverse effects of frame deformation, reducing the stress concentration of the guide sleeve 50, and improving the service life.

[0057] Example 2

[0058] Combination Figures 4 to 5 As shown, this embodiment is basically the same as the embodiment 1, except that the guide sleeve 50 includes a plurality of guide sleeve segments 501, and the plurality of guide sleeve segments 501 are arranged along the circumference of the guide column 40; there is a gap between two adjacent guide sleeve segments 501. In this embodiment, the guide sleeve 50 is separated into a plurality of guide sleeve segments 501, because there is a gap between two adjacent guide sleeve segments 501, even if the guide sleeve segments 501 are deformed, it is very convenient to remove the guide sleeve 50. In addition, the gap can also be regarded as an oil path to increase the lubrication effect.

[0059] Preferably, the guide sleeve 50 is divided into two guide sleeve split bodies 501 disposed in halves.
