DETAILED DESCRIPTION

[0020] The utility model will be explained in detail in combination with the drawings and embodiments.

[0021] Embodiment: a kind of upper guide shoe inclined wedge clamp, the clamp 6 is used to hold fixedly to upper guide shoe inclined wedge 2, to adjust the gap of the upper guide shoe, i.e. clamp 6 will be combined into corresponding gap adjusting tool together with use, for the sake of understanding the technical scheme of the utility model, the following is explained in detail in combination with adjusting tool. As Figure 1As shown, the upper guide shoe comprises a pad 1 and a wedge 2, the pad 1 is in the shape of "U" in the cross section along its length direction, the wedge 2 is arranged in the groove formed by the pad 1, the wedge 2 is in sliding connection with the pad 1 and can slide along the length direction of the wedge 2, the side of the wedge 2 facing the groove is arranged in an inclined manner along its length direction, a strip-shaped through hole 3 is formed in the middle of the wedge 2 along its length direction, and the wedge 2 has a first measuring surface 4 perpendicular to its length direction;

[0022] As shown in the drawings, Figure 2 The gap adjusting tool comprises a frame 5 and a lifting mechanism 10.

[0023] The frame 5 is used for connecting and fixing the pad 1, and the frame 5 has a second measuring surface 11, which is parallel to the first measuring surface 4 of the wedge 2 after the pad 1 is connected and fixed to the frame 5.

[0024] As shown in the drawings, Figure 5 And Figure 6 The clamp 6 is used for connecting and fixing the wedge 2, the clamp 6 has a clamping surface 8 used for abutting the top surface of the wedge 2, and the clamping bolt 9 is threadedly connected to the clamping block 7, and a clamping area is formed between the shank of the clamping bolt 9 and the clamping surface 8, and the clamping area can limit and fix the part between the strip-shaped through hole 3 and the top surface of the wedge 2 after the clamping bolt 9 is screwed into the clamping block 7. In order to facilitate the adjustment of the gap, the clamp 6 needs to have a lifting function, and in order to achieve this purpose, the clamping block 7 of the clamp 6 can be in the form of a sliding block and is in sliding connection with the frame 5, and a sliding groove is formed in the frame 5 for the sliding block to slide, and the sliding block is in sliding connection with the frame 5 and can slide along the normal direction of the second measuring surface 11; after the pad 1 is connected and fixed to the frame 5, the clamping bolt 9 is screwed into the sliding block and abuts the end of the strip-shaped through hole 3, a clamping area is formed between the clamping bolt 9 and the clamping surface 8, and the clamping area limits and fixes the part between the strip-shaped through hole 3 and the top surface of the wedge 2;

[0025] The lifting mechanism 10 is arranged on the frame 5 and is connected with the sliding block for driving the sliding block to slide on the frame 5.

[0026] The main idea of the adjusting tool is to fix the pad 1 through the frame 5, fix the wedge 2 through the clamp 6, drive the clamp 6 through the lifting mechanism 10, adjust the gap by the clamp 6 carrying the wedge 2 to rise and fall or slide on the pad 1, and determine whether the adjusted gap is appropriate by measuring the distance between the first measuring surface and the second measuring surface through the measuring tool.

[0027] Compared to conventional adjustment methods, this adjustment fixture fixes both pad 1 and wedge 2 separately, allowing the adjuster to focus on measurement. It is simple to operate, highly efficient, less dependent on highly skilled personnel, and the adjustment process is precise, controllable, and safe. Furthermore, the variety of tools greatly reduces the possibility of tools being lost in the upper guide bearing, thus lowering the risk of equipment damage.

[0028] Because the wedge 2 is flat, smooth, and has sharp edges with no stress points, a wedge 2 clamp 6 is designed to address these characteristics. A clamping bolt 9 is used in conjunction with a clamping surface 8. The clamping surface 8 can be formed by extending one side of the slider horizontally outwards, or a separate pressure block can be made and connected to one side of the slider, with the bottom surface of the pressure block serving as the clamping surface 8. The clamping bolt 9 is horizontally positioned on the slider and passes through it. When the wedge 2 connects to the slider, the slider is located on the side of the wedge 2 furthest from the groove, and the clamping bolt 9 is located on the side of the slider furthest from the wedge 2. The vertical distance between the clamping bolt and the clamping surface 8 is determined based on the distance between the upper end of the strip-shaped through hole 3 and the first measuring surface 4. During the tightening of the clamping bolt 9, the clamping bolt 9 and the clamping surface 8 work together to press the wedge 2, connecting the slider and the wedge 2 as a whole. To facilitate the tightening of the clamping bolt 9, an internal hexagonal hole can be provided at its head. Generally speaking, there are two strip-shaped through holes 3 on the wedge 2, and they are symmetrically arranged with respect to the center line of the wedge 2. Therefore, the clamping bolts 9 can also be set to two accordingly.

[0029] like Figures 2-4 As shown, the frame 5 is a U-shaped structure with the opening facing downwards, and the bottom of the opposite sides of the two side walls of the frame 5 are respectively provided with grooves 12 that cooperate with the top and side surfaces of the pad block 1.

[0030] The frame 5 is attached to the pad 1 through the grooves 12 on both sides. The grooves 12 limit the pad 1 by fitting the top surface and three sides of the pad 1. The two grooves 12 cooperate with the top two sides of the pad 1 to actually limit the pad 1 in the horizontal direction.

[0031] On the opposite sides of the two side walls of the frame 5, corresponding to the groove 12, there are locking nuts for fixing the pad 1.

[0032] The pad 1 is clamped from both sides by locking nuts to prevent the pad 1 from moving up and down. Together with the groove 12, the pad 1 is fixed and the frame 5 is connected to the pad 1.

[0033] The top of the groove 12 has an outwardly expanding slope. Guided by the slope, the pad 1 can be inserted into the groove 12 more easily and quickly.

[0034] The top surface of the wedge 2 is a first measuring surface 4, and the top surface of the frame body 5 is a second measuring surface 11. A measuring hole 13 is formed in the top wall of the frame body 5 along the normal direction of the second measuring surface 11 and penetrates the top wall of the frame body 5.

[0035] The result of the gap adjustment can be reflected by measuring the distance between the first measuring surface 4 and the second measuring surface 11. In order to facilitate the use of a measuring tool such as a depth vernier caliper, the measuring hole 13 is formed in the top wall of the frame body 5. The measuring base of the depth vernier caliper is placed on the second measuring surface 11, the scale of the depth vernier caliper is inserted into the measuring hole 13 and is in contact with the first measuring surface 4 of the wedge 2 below, and then the distance between the first measuring surface 4 and the second measuring surface 11 can be measured.

[0036] In order to further improve the measuring efficiency, a measuring rod which can slide along the axial direction is slidably connected in the measuring hole 13. A scale is formed on the surface of the measuring rod along the axial direction. The bottom end of the measuring rod is in contact with the first measuring surface 4. When the lifting mechanism 10 drives the wedge 2 to lift, the wedge 2 also drives the measuring rod to lift. The adjuster can quickly understand the distance between the first measuring surface 4 and the second measuring surface 11 by observing the scale on the measuring rod, so as to determine whether the gap is adjusted to be appropriate. Of course, the bottom end of the measuring rod can also extend into the sliding block, and the zero line of the measuring rod can be aligned with the first measuring surface 4 after the wedge 2 is fixed. The measuring rod can also function as a guide rod by being fixed in the sliding block and being driven to lift. The sliding block is limited, which can prevent the sliding block from tilting and thus lifting smoothly.

[0037] In order to avoid damage to the wedge 2 caused by the clamping bolt 9, a sleeve 14 is sleeved on the end of the screw rod of the clamping bolt 9 away from the head. The sleeve 14 and the clamping surface 8 form a clamping area. The wedge 2 is protected by the sleeve 14.

[0038] Of course, in order to ensure that the clamping force is sufficient, the outer surface of the sleeve 14 can be conical, and the outer diameter gradually increases from the screw rod to the head of the clamping bolt 9. As the clamping bolt 9 is screwed in, the clamping force between the conical sleeve 14 and the clamping surface 8 gradually increases.

[0039] Further, the material of the sleeve 14 can also be flexible rubber to prevent the wedge 2 from being clamped.

[0040] The lifting mechanism 10 includes a lead screw 15 which is threadedly connected with the frame body 5 and is rotationally connected with the sliding block.

[0041] A screw hole is formed in the top wall of the frame body 5 to cooperate with the lead screw 15. The screw hole can be a fine thread to improve the adjustment accuracy. For example, Figure 7As shown in the drawings, a simple implementation mode of the rotating connection between the lead screw 15 and the sliding block can be that a hole position connected with the bottom end of the lead screw 15 is arranged on the sliding block, an annular groove is arranged on the outside of the bottom end of the lead screw 15, the side of the hole position deviates from the center and is located at the plug hole, the bottom end of the lead screw 15 is placed into the hole position, the plug 16 is placed into the plug hole from the side, the plug 16 passes through the groove, the limiting of the lead screw 15 is completed, the lead screw 15 is prevented from being separated from the hole position, and meanwhile the lead screw 15 can also rotate in the hole position. In order to facilitate the rotation of the lead screw 15, an inner hexagonal hole can be arranged at the top end of the lead screw 15, and of course, in order to stably connect the plug 16, the plug 16 and the plug hole can be threadedly connected.

[0042] The above-described embodiments only express the specific implementation modes of the present application, the description is relatively specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for the ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
