[0002] A needle roller bearing is a roller bearing with cylindrical rollers. Relative to its diameter, the rollers are both thin and long. Such rollers are called needle rollers. After installation, the needle roller bearing ensures that the end faces of the outer ring body and the inner ring body are horizontal, and ensures that the axes of the rollers are parallel to the axis of the outer ring body or the inner ring body to avoid eccentric wear.

[0003] The application number is CN201520509286.6, which discloses a bearing assembly measuring tooling. The key points are as follows: one end of the tooling body is an assembly end, the other end is a measuring end, and a circular positioning cylinder is provided in the center, and a circular supporting flange is provided on its inner circumferential surface; on the outer circumference of the circular positioning cylinder at the assembly end, there is a circular assembly step with a supporting surface, and a circular groove is formed between the circular assembly step and the circular positioning cylinder; on the outer cylindrical surface of the circular positioning cylinder at the measuring end, there is a circular measuring step with a supporting surface. The bearing assembly measuring tooling of the utility model has the advantages of simple structure, small volume, light weight, convenient operation and use. When the assembly end face of the tooling is upward and the bearing seat is placed on the assembly supporting surface, the assembly can be completed. When the measuring end face of the tooling is upward, the axial clearance measurement of the bearing can be completed. The assembly and measurement reliability is good; one set of tooling can complete the assembly and clearance measurement of the bearing, reduce the production cost, save the tooling replacement time, improve the production efficiency, and has good economy.

The movable block 109 is installed on the lead screw 205, and then the movable block 109 is fixed to the clamping block 108 through the bolt 200. When the lead screw 205 rotates, it will drive the spirit level 204 to move in the vertical direction. It is limited and slides on the guide rail 105 through the four sliders 106. The periphery of the fixing plate 107 is horizontally fixed on the support base 103, making it more stable when moving the fixing plate 107 up and down. The mounting plate 202 is set to be connected by bolts 200, which is convenient for disassembling and installing the mounting plate 202 and the spirit level 204 for replacement and repair.

[0026] The sliding component 1 includes an operating table 101. Four limit blocks 102 are arranged on the upper surface of the operating table 101.
