Description

Technical Field

[0001] This utility model relates to the field of roller technology, and in particular to a single-load roller deformation resistance testing device. Background Technology

[0002] Rollers are the load-bearing components of a bearing during operation and are the weakest parts in a roller bearing. Their manufacturing quality has a significant impact on the bearing's performance (such as rotational accuracy, vibration, noise, and flexibility) and is a major factor affecting the bearing's service life. During the manufacturing process, the rollers are dimensionally inspected after completion to check for consistency in dimensions and to understand the tolerances in the manufacturing process. This calibration device is used to perform dimensional inspection on the roller structure.

[0003] When inspecting rollers, a measuring tool is usually used to measure them. However, ordinary dimensional measurement is inefficient and requires measuring each roller individually, making it difficult to adapt to batches of rollers and hindering rapid comparative testing of batches. Utility Model Content

[0004] The purpose of this invention is to provide a single-load roller deformation resistance testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A single-load roller deformation resistance testing device includes a chassis, an L-shaped top seat on the top of the chassis, cylindrical columns connected to the end walls of the top seat, rectangular bases fixed to the top walls of the columns, and a pair of rectangular measuring plates movably connected to the bases.

[0007] Preferably, the chassis is in the shape of a concave character, and a rectangular side opening is provided on the side wall of the concave bottom of the chassis, and a buckle is engaged in the side opening.

[0008] Preferably, a rectangular support plate for placing the roller is fixed to the side wall of the buckle, and two support plates are provided. Four slots similar to the buckle are opened on the front side wall of the top of the chassis.

[0009] Preferably, a rectangular slide bar is fixedly connected to the top side wall of the recess in the chassis, and a pair of rectangular slide blocks are movably connected to the slide bar.

[0010] Preferably, the top wall of the chassis has a pair of rectangular slides, a slider is movably connected in the slide, the slide block passes through the slide and is fixed to the top seat through the slider, the top seat and the top seat move with the slide and the slide, and a screw is threadedly connected to the front wall of the slide.

[0011] Preferably, the fixed base has a sliding interface, which is movably connected to the measuring plate.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. During measurement, a large number of rollers are placed vertically on the upper wall of the bottom of the top seat. The measuring plates at the sliding interface are moved so that the two measuring plates are close together and the end walls of the measuring plates contact the end walls of the rollers. At this time, when the rollers are of uniform size, it can be observed that each roller is in contact with the end walls of the two measuring plates. Conversely, the end walls of a few rollers with inconsistent sizes do not contact the end walls of the measuring plates. This makes it easy to quickly measure and identify the size of the rollers and the tolerances between the rollers.

[0014] 2. A scale mark is provided on the front wall of the fixed base near the sliding interface to facilitate the identification of the measurement values ​​of the measuring plate. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a single-load roller deformation resistance testing device:

[0023] like Figure 1-4 As shown, a single-load roller deformation resistance testing device includes a chassis 1, an L-shaped top seat 11 on the top of the chassis 1, cylindrical columns 12 connected to the two end walls of the top seat 11, a rectangular base 13 fixed to the top wall of the column 12, a pair of rectangular measuring plates 15 movably connected to the base 13, and a sliding interface 14 opened in the base 13, the sliding interface 14 being movably connected to the measuring plates 15.

[0024] The chassis 1 is in the shape of a concave character. A rectangular side opening 2 is provided on the concave side wall of the bottom of the chassis 1. A buckle 3 is snapped into the side opening 2. A rectangular support plate 4 for placing the roller is fixed to the side wall of the buckle 3. There are two support plates 4. Four slots 8 similar to the buckles 3 are provided on the front side wall of the top of the chassis 1.

[0025] A rectangular slide bar 5 is fixed to the top side wall of the recess in the chassis 1, and a pair of rectangular slide blocks 6 are movably connected to the slide bar 5.

[0026] The top wall of the chassis 1 has a pair of rectangular slides 9. A slider 10 is movably connected in the slides 9. The slide seat 6 passes through the slides 9 and is fixed to the top seat 11 through the slider 10. The top seat 11 moves with the slides 9 through the slider 10. A screw 7 is threadedly connected to the front wall of the slide seat 6.

[0027] Working principle:

[0028] During measurement, a large number of rollers are placed vertically on the bottom upper wall of the top seat 11. The measuring plate 15 at the sliding interface 14 moves so that the two measuring plates 15 are close together and the end wall of the measuring plate 15 contacts the end wall of the roller. At this time, when the placed rollers are of uniform size, it can be observed that each roller is in contact with the end wall of both measuring plates 15. Conversely, the end walls of a very small number of rollers with inconsistent sizes do not contact the end walls of the measuring plates 15, which facilitates quick measurement and identification of the roller size and the tolerance between rollers.

[0029] The base 13 has a scale mark on the front wall near the sliding interface 14 to facilitate the identification of the measurement value of the measuring plate 15;

[0030] Move the slide block 6, slide rail 9, and slider 10 to move the top seat 11. After the top seat 11 moves to the side, its position is changed, making it more flexible and convenient to use. Tighten the screw 7 to lock and limit the top seat 11 after the position is adjusted.

[0031] When the support plate 4 is removed, the buckle 3 is inserted into the slot 8 to form a snap-fit. At this time, the support plate 4 is laterally supported on the side of the chassis 1, which can place and support the rollers, making it convenient to temporarily store the rollers and to store and retrieve them easily.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
