Abstract
Description
Technical Field
[0001] The utility model belongs to the field of engineering machinery, and particularly relates to an auxiliary tool for measuring the axial distance of bearings. Background Art
[0002] At present, special auxiliary measuring tooling is widely used in the assembly and processing of engineering machinery. It is used in the production and assembly of relatively mature products in large quantities. It is difficult to achieve accurate measurement using conventional measurement methods and conventional measuring instruments, which makes subsequent processing and assembly difficult. Utility Model Content
[0003] The purpose of the utility model is to provide an auxiliary tool for measuring the axial distance of a bearing, so as to solve the measurement problems caused by the narrow space and small measuring surface during the assembly measurement process.
[0004] The auxiliary tooling for measuring the axial distance of bearings includes a screw handle, a slide rod and a tooling housing; the screw handle is rotated downward in the thread, so that the conical surface of the screw handle contacts and squeezes the conical arc surfaces on the three horizontal slide rods in the housing; the front section of the slide rod is a rectangular parallelepiped, and the rear section is a cylinder. A spring is installed outside each rectangular parallelepiped, and the end face of the rectangular parallelepiped is fixed to the pressure block.
[0005] Furthermore, the working surface of the pressing block is an arc surface, the end surface of the cuboid and the pressing block are fixed by screws, and the surface of the screws is lower than the arc surface.
[0006] Furthermore, the housing is an integrated structure.
[0007] The beneficial effects of the present invention are:
[0008] 1. The utility model can be applied to the measurement of the axial distance of a small contact surface, converting the small contact surface into a large contact surface, making the measurement simpler and avoiding the error caused by the unchanged measurement.
[0009] 2. The slide bar of the utility model adopts a two-section structure. The front section is a rectangular parallelepiped structure, which enables the slide bar to move in a single direction, thus avoiding the possibility of rotation of the cylindrical slide bar.
[0010] 3. The threaded cone rod of the utility model adopts the cone to move downward to squeeze three horizontal slide bars to achieve the purpose of adjustment. The rising and falling rates can be achieved by adjusting the cone angle and the thread pitch. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] like Figures 1-4 As shown, the auxiliary tooling for measuring the axial distance of the bearing includes a screw handle 1, a slide rod 5 and a tooling housing 6; the screw handle 1 rotates downward in the thread, so that the conical surface of the screw handle 1 contacts and squeezes the conical arc surfaces on the three horizontal slide rods 5 in the housing, and the three slide rods move evenly in their respective horizontal directions, and the rate of rise and fall is achieved by adjusting the cone angle and the thread pitch; the front section of the slide rod 5 is a rectangular parallelepiped, and the rectangular parallelepiped structure of the front section enables the slide rod to move in a single direction, avoiding the possibility of the cylindrical slide rod easily rotating; the rear section is a cylinder, and a spring 4 is installed outside each rectangular parallelepiped. When the slide rod moves outward, it squeezes the spring, and the spring is in a contracted state. When the screw rotates, the slide rod 5 slides inward under the action of the elastic force of the spring 4, and the spring 4 returns to its natural state. The end face of the rectangular parallelepiped is fixed to the pressing block 3.
[0017] The working surface of the pressing block 5 is an arc surface. The end surface of the cuboid is fixed to the pressing block 3 by screws 2, and the surface of the screws is lower than the arc surface.
[0018] The housing 6 is processed in one piece. Since the slide bar 5 is larger inside and smaller outside, it can only be drilled through from one side, and then the inner rectangular groove is processed, and then the slide bar 5 is installed in the housing.
[0019] When using, first place the tool above the bearing end face to be measured, slowly adjust the screw handle clockwise, and wait until the three pressure blocks 5 press the workpiece. Be sure to keep the tool end face and the bearing end face flush. At this time, measure the axial distance at the edge. As long as the tool surface is measured and the tool thickness h is added, the distance to the bearing end face can be calculated. The operation is simple and the accuracy is high. After the measurement, turn the screw handle back to its original position to avoid the spring being in a compressed state for a long time, which affects its stiffness.
[0020] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
