[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Example: A tooling for adjusting the gap of the upper guide tile, such as Figure 1 As shown, the upper guide tile includes a pad 1 and a wedge 2. The cross-section of the pad 1 along its length is U-shaped. The wedge 2 is disposed in the groove formed by the pad 1. The wedge 2 is slidably connected to the pad 1 and can slide along the length of the wedge 2. The side of the wedge 2 facing the groove is inclined along its length. A strip-shaped through hole 3 is opened in the middle of the wedge 2 along its length. The wedge 2 has a first measuring surface 4 perpendicular to its length.

[0032] like Figure 2 As shown, the gap adjustment fixture includes a frame 5, a slider 6, a lifting mechanism 7, and a clamp 8;

[0033] The frame 5 is used to connect and fix the pad 1. The frame 5 has a second measuring surface 9. After the pad 1 is connected and fixed to the frame 5, the second measuring surface 9 is parallel to the first measuring surface 4 of the wedge 2.

[0034] The slider 6 is slidably connected to the frame 5 and can slide along the normal direction of the second measuring surface 9. A groove is provided on the frame 5 for the slider 6 to slide.

[0035] The lifting mechanism 7 is arranged on the frame body 5 and connected with the sliding block 6 for driving the sliding block 6 to slide on the frame body 5.

[0036] The clamp 8 is arranged on the sliding block 6 for abutting one end of the strip-shaped through hole 3 to connect the inclined wedge 2 and the sliding block 6 and drive the inclined wedge 2 to slide on the pad 1 under the action of the lifting mechanism 7.

[0037] The main idea of the adjustment tool is to fix the pad 1 through the frame body 5, fix the inclined wedge 2 through the clamp 8, drive the clamp 8 through the lifting mechanism 7, and adjust the gap by lifting or sliding the inclined wedge 2 on the pad 1 through the strip-shaped through hole 3, and determine whether the adjusted gap is appropriate by measuring the distance between the first measurement plane and the second measurement plane through the measuring tool.

[0038] Compared with the conventional adjustment method, the pad 1 and the inclined wedge 2 are fixed respectively, the adjuster can focus on measurement, the operation is simple, the adjustment efficiency is high, the dependence on high-skilled personnel is low, the adjustment process is accurate and controllable, the safety is high, and the types of tools and instruments are greatly reduced, so that the possibility of losing tools and instruments in the upper bearing is reduced, and the risk of equipment damage is reduced.

[0039] As shown in Figures 2-4 The frame body 5 is in the shape of "U" with the opening downward, and the opposite side bottoms of the two side walls of the frame body 5 are respectively provided with embedding grooves 10 matched with the top surface and the side surface of the pad 1.

[0040] The frame body 5 is tightly attached to the pad 1 through the embedding grooves 10 on both sides, and the embedding grooves 10 limit the pad 1 through the cooperation of the top surface and the three side surfaces with the pad 1. The two embedding grooves 10 are respectively matched with the top two sides of the pad 1 to limit the pad 1 in the horizontal direction.

[0041] The opposite sides of the two side walls of the frame body 5 are respectively provided with locking nuts for fixing the pad 1 at the positions corresponding to the embedding grooves 10.

[0042] The pad 1 is clamped from both sides by the locking nuts to prevent the pad 1 from moving up and down, and the pad 1 is fixed together with the embedding grooves 10 to realize the connection between the frame body 5 and the pad 1.

[0043] The top of the embedding groove 10 has an outwardly expanding inclined surface. Through the guidance of the inclined surface, the pad 1 can be more conveniently and quickly loaded into the embedding groove 10.

[0044] The top surface of the inclined wedge 2 is the first measurement plane 4, the top surface of the frame body 5 is the second measurement plane 9, and the top wall of the frame body 5 is provided with a measurement hole 11 penetrating the top wall of the frame body 5 along the normal direction of the second measurement plane 9.

[0045] The result of the gap adjustment can be reflected by measuring the distance between the first measuring surface 4 and the second measuring surface 9. In order to facilitate the use of a measuring tool such as a depth vernier caliper, a measuring hole 11 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 9, the ruler of the depth vernier caliper is inserted into the measuring hole 11 and is in contact with the first measuring surface 4 of the inclined wedge 2 below, and then the distance between the first measuring surface 4 and the second measuring surface 9 can be measured.

[0046] In order to further improve the measuring efficiency, a measuring rod which can slide along the axial direction is connected in the measuring hole 11, the surface of the measuring rod is provided with scale lines along the axial direction, the measuring rod is used instead of the depth vernier caliper, the bottom end of the measuring rod is in contact with the first measuring surface 4, when the lifting mechanism 7 drives the inclined wedge 2 to lift, the inclined wedge 2 also drives the measuring rod to lift, and the adjuster can quickly understand the distance between the first measuring surface 4 and the second measuring surface 9 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 6, and it is ensured that the zero scale line of the measuring rod is aligned with the first measuring surface 4 after the inclined wedge 2 is fixed. The measuring rod is fixed by the sliding block 6 and is driven to lift, so that the measuring rod can also play the role of a guide rod, the sliding block 6 is limited, and the effect of preventing the sliding block 6 from tilting and thus lifting is sluggish can be achieved.

[0047] As shown in Figure 5 and Figure 6 , one side of the sliding block 6 has a clamping surface 12 for abutting the top surface of the inclined wedge 2, the clamp 8 includes a clamping bolt 13 arranged on the sliding block 6, when the pad 1 is connected and fixed with the frame body 5, the clamping bolt 13 is screwed into the sliding block 6 and abuts the end of the strip-shaped through hole 3, a clamping area is formed between the clamping bolt 13 and the clamping surface 12, and the clamping area limits and fixes the part between the strip-shaped through hole 3 and the top surface of the inclined wedge 2.

[0048] One of the focuses of the present adjustment tool is the design of the clamp 8. Since the wedge 2 is flat and smooth with clear corners and no stress points, the wedge 2 clamp 8 is designed according to the characteristics of the wedge 2. The clamp 8 is installed on the sliding block 6, and the clamping bolt 13 cooperates with the clamping surface 12. The clamping surface 12 can be formed by extending one side of the sliding block 6 outward horizontally, or a separate pressing block can be made and connected to one side of the sliding block 6, so that the bottom surface of the pressing block serves as the clamping surface 12. The clamping bolt 13 is arranged horizontally on the sliding block 6 and passes through the sliding block 6. When the wedge 2 is connected to the sliding block 6, the sliding block 6 is located on the side of the wedge 2 away from the groove, and the clamping bolt 13 is located on the side of the sliding block 6 away from the wedge 2. The vertical distance between the clamping bolt 13 and the clamping surface 12 is set according to 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 13, the clamping bolt 13 cooperates with the clamping surface 12 to press the wedge 2 tightly, and the sliding block 6 and the wedge 2 are connected as a whole. In order to facilitate the tightening of the clamping bolt 13, the head of the clamping bolt 13 can be provided with an internal hexagonal hole. Generally, the wedge 2 has two strip-shaped through holes 3, which are symmetrically arranged with the center line of the wedge 2. Therefore, the clamping bolt 13 can also be correspondingly provided with two clamping bolts.

[0049] In order to avoid damage to the wedge 2 caused by the clamping bolt 13, the end of the shank of the clamping bolt 13 away from the head is sleeved with a sleeve 14. The sleeve 14 and the clamping surface 12 form a clamping area, and the wedge 2 is protected by the sleeve 14.

[0050] Of course, in order to ensure that the clamping force is sufficient, the outer surface of the sleeve 14 can also be tapered, and the outer diameter gradually increases from the shank of the clamping bolt 13 to the head. In this way, as the clamping bolt 13 is screwed in, the clamping force between the tapered sleeve 14 and the clamping surface 12 will gradually increase.

[0051] The lifting mechanism 7 includes a lead screw 15, which is threadedly connected with the frame 5 and rotationally connected with the sliding block 6.

[0052] A screw hole is formed in the top wall of the frame 5 to cooperate with the lead screw 15. The screw hole can be a fine thread to improve the adjustment accuracy. Figure 7 As shown in FIG. 6, a simple implementation way of the rotationally connected lead screw 15 and sliding block 6 can be that a hole is arranged on the sliding block 6 and connected with the bottom end of the lead screw 15. The outer side of the bottom end of the lead screw 15 is provided with an annular groove. The side of the hole deviating from the axis is located in the plug hole 16. After the bottom end of the lead screw 15 is placed in the hole, the plug 16 is placed in the plug hole from the side, so that the plug 16 passes through the groove, limiting the lead screw 15, avoiding the lead screw 15 from being separated from the hole, and the lead screw 15 can also rotate in the hole. In order to facilitate the rotation of the lead screw 15, an internal hexagonal hole can be arranged at the top end of the lead screw 15. Of course, in order to stably connect the plug 16, the plug 16 and the plug hole can be threadedly connected.

[0053] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
