Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to bearing detection technical field, concretely is a bearing inner raceway groove diameter detection device. BACKGROUND
[0002] Bearing needs to carry out sampling detection to the semi -finished product of production frequently in the production process to reduce the production of waste products. For miniature bearing, the inside groove diameter of bearing outer ring needs to be measured and inspected, and bearing measuring instrument is usually used.
[0003] Such as the publication number: CN212692838U, provides a bearing measuring instrument, the scheme can realize the lifting of tray through the rotation knob to adjust the distance of tray and positioning contact, sets up the accommodation groove, makes the first positioning piece not and tray interference in the moving process, sets up spring seat to realize that the positioning contact is pressed against the inner raceway groove of bearing outer ring. But its volume is big, inconvenient to transfer, and its inside is set through spring, and the spring will lose its original performance after long time use, inconvenient to replace.
[0004] In order to solve the above problem, the case is thus born. UTILITY MODEL CONTENT
[0005] (I) the technical problem solved
[0006] The utility model is to provide a bearing inner raceway groove diameter detection device to solve the problems in the background art.
[0007] (II) technical scheme
[0008] To achieve the above object, the utility model is realized by the following technical scheme: a bearing inner raceway groove diameter detection device, including scale table and measuring ring, the scale table is circular table, the measuring ring includes circular ring, a plurality of through grooves are set up on the side surface of circular ring, the through groove is slidably connected with contact head slider, the both ends of contact head slider are respectively from the both sides of through groove, the left and right sides of one end of contact head slider in circular ring is equipped with fixed sheet, and the inside surface between fixed sheet and circular ring is equipped with spring.
[0009] Preferably, the end face width of one end of contact head slider in the inside of circular ring is greater than the width of contact head slider itself, and the end head of one end of contact head slider on the outside of circular ring is arc head.
[0010] Preferably, the side surface of scale table is equipped with vertical scale bar and annular alignment line.
[0011] Preferably, the left and right sides of one end of contact head slider on the outside of circular ring are equipped with limit block close to end head.
[0012] Preferably, both ends of the spring are secured to the fixing plate and the ring.
[0013] (III) Beneficial Effects
[0014] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The bearing inner ring groove diameter detection device of this utility model can quickly measure the bearing inner ring groove diameter by using the cooperation of the scale stage and the measuring ring, and the spring on the measuring ring is exposed, so it can be quickly replaced when the spring gradually loses its performance.

[0017] In the diagram: 1. Scale platform, 2. Measuring ring, 3. Circular ring, 4. Contact slider, 5. Fixing plate, 6. Spring, 7. Limiting block. Detailed Implementation
[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0019] This utility model provides a bearing inner ring groove diameter detection device, such as... Figures 1-2 As shown, the device includes a scale platform 1 and a measuring ring 2. The scale platform 1 is frustum-shaped. The measuring ring 2 includes a circular ring 3. Several through slots are formed on the side of the circular ring 3. Contact sliders 4 are slidably connected within the through slots. The two ends of the contact slider 4 protrude from the two sides of the through slots. Fixing plates 5 are provided on the left and right sides of the end of the contact slider 4 located inside the circular ring 3. A spring 6 is provided between the fixing plates 5 and the inner side of the circular ring 3. Both ends of the spring 6 are secured to the fixing plates 5 and the circular ring 3, allowing for convenient and quick replacement of the spring 6 when needed.
[0020] Reference Appendix Figure 1 The width of the end face of the contact slider 4 located inside the ring 3 is greater than the width of the contact slider 4 itself, and the end of the contact slider 4 located outside the ring 3 has an arc-shaped end. Limiting blocks 7 are provided on the left and right sides of the end of the contact slider 4 located outside the ring 3 near the end to prevent the contact slider 4 from falling out.
[0021] Reference Appendix Figure 1 The scale stage 1 has vertical scale bars and annular alignment lines on its side. When in use, the measuring ring 2 is inserted into the inner ring of the bearing to be measured, and then the hollow area in the middle of the measuring ring 2 is inserted into the scale stage 1. The side of the scale stage 1 pushes out the contact slider 4 until it can no longer move downwards. After one end of the arc-shaped head of the contact slider 4 is aligned with the annular alignment line, the vertical scale can be read to quickly complete the measurement of the inner ring groove diameter of the bearing.
[0022] The utility model discloses a bearing inner race groove diameter detection device, utilize the cooperation of graduated table and measuring ring can fast to bearing inner race groove diameter carries out the measurement, and spring on the measuring ring is exposed, when spring gradually loses the performance, can fast to it carry out the replacement.
[0023] Although the embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
