Description

Technical Field

[0001] This utility model relates to the field of bearing ring detection technology, and in particular to an automatic bearing ring size detection mechanism. Background Technology

[0002] Bearing rings are an important component of bearings. They are ring-shaped parts used to support the rolling elements (such as balls or rollers) in the bearing and maintain the bearing's structure and shape. Bearing rings are generally divided into two types: inner rings and outer rings. The inner ring is the bearing component mounted on the shaft, and its inner diameter fits tightly with the shaft. The inner ring usually has one or two shoulders to secure it to the shaft and prevent slippage. The outer ring is the bearing component mounted on the bearing housing or machine casing, and its outer diameter fits with the bearing housing bore. The outer ring is usually designed with mounting grooves or holes to facilitate installation and removal.

[0003] The dimensions of bearing races are key parameters in bearing design and application, determining the bearing's load capacity, lifespan, and fit with the shaft and housing. The dimensions of bearing races include the following aspects: inner diameter, outer diameter, and width:

[0004] The inner diameter of the inner ring is the fitting dimension when the bearing is installed on the shaft. This dimension is crucial for ensuring the correct positioning of the bearing on the shaft. The outer diameter of the outer ring is the fitting dimension between the bearing and the bearing housing bore. This dimension determines the tightness of the fit between the bearing and the bearing housing. The width of the raceway refers to the distance between the two sides of the raceway, which is important for determining the overall dimensions of the bearing.

[0005] Currently, there are a large number of existing bearings, resulting in a wide variety of bearing sizes. Therefore, a testing device capable of detecting multiple different models and sizes is needed to ensure compatibility and avoid the redundancy caused by developing multiple sets of testing devices. To this end, we propose an automatic bearing ring size detection mechanism. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides an automatic bearing ring size detection mechanism, solving the technical problem of compatible detection of various bearing ring sizes.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] The automatic bearing ring size detection mechanism includes a chassis consisting of two sets of mutually perpendicular horizontal and vertical plates. A drive mechanism is located on the back of the vertical plate, while two sets of rolling mechanisms are rotatably mounted on the front of the vertical plate via bearings. The drive mechanism is connected to the rolling mechanisms via multiple chains. Bearing rings are placed above the rolling mechanisms. An upper clamping block is located on the upper inner side of the vertical plate. The downward pressure of the upper clamping block, in conjunction with the rolling mechanisms, clamps the bearing rings. The drive mechanism then drives the rolling mechanisms to rotate.

[0011] Preferably, a base is provided above the horizontal plate, and two sets of adjustment mechanisms are provided at the upper end of the base. The adjustment mechanisms are equipped with an inner diameter measuring head. The inner diameter measuring head is fitted to the inside of the bearing ring to measure the inner diameter, and the other set of bearing rings can also measure the outer diameter of the bearing ring.

[0012] Preferably, the adjustment mechanism above the base is symmetrically arranged in two sets, each including two sets of inner diameter measuring heads, which can perform two sets of inner diameter measurements or a combination of inner and outer diameter measurements, and can be flexibly selected according to the requirements of the bearing rings.

[0013] Preferably, the position of the adjustment mechanism needs to be adjustable to accommodate the needs of more position measurements. The two sets of adjustment mechanisms are symmetrically distributed. The following description will take one of the sets as an example. The adjustment mechanism includes a bottom fixed plate, and a Y-axis adjustment block and an X-axis adjustment block are set on the upper end of the bottom fixed plate.

[0014] Preferably, an upper fixed block is provided at the upper end of the X-axis adjusting block, and an inner diameter measuring head is fixedly installed on the upper end of the upper fixed block by a clamp. The inner diameter measuring head contacts the inner ring of the bearing race to adjust the inner diameter. The X-axis adjusting block is a rocker mechanism in the X-axis direction, which realizes the adjustment of the upper fixed block and the inner diameter measuring head as a whole in the X-axis direction. The Y-axis adjusting block is a rocker mechanism in the Y-axis direction. By adjusting the position of the upper X-axis adjusting block in the Y-axis direction, the Y-axis direction adjustment of the inner diameter measuring head is indirectly realized. The overall adjustment of the horizontal position of the inner diameter measuring head is realized, thereby better meeting the processing requirements of various sizes and models.

[0015] Preferably, a sensor is provided on the outer side of the inner diameter measuring head. The inner diameter measuring head is pressed tightly against the inner side of the bearing ring to measure the size. The sensor receives the information and transmits it to the computer for signal conversion to complete the measurement of the part.

[0016] Preferably, an external measuring module is bolted to the upper center of the bottom fixed plate. The external measuring module includes a support frame with a groove. The position of the support frame in the Y-axis direction can be adjusted by selecting different positions of the groove through the bolts. In addition, a clamping block is provided at the front center of the support frame, and a slot is provided in the center of the clamping block. Two sets of adjustable components are slidably installed thereon. The sliding position of the two sets of adjustable components is fixed by a clamping block to match the measurement of the bearing ring size.

[0017] Preferably, a rolling block is rotatably mounted on the outside of the adjustable component, which contacts the side wall of the bearing ring and is used in conjunction with the rolling mechanism for overall installation and locking.

[0018] (III) Beneficial Effects

[0019] The bearing rings are clamped by the downward pressure of the upper clamping block and the overall rolling mechanism. The rolling mechanism is driven to rotate by the drive mechanism, and the lateral external measurement module provides lateral support and lateral measurement.

[0020] By adjusting the position of the upper X-axis adjustment block in the Y-axis direction, the Y-axis direction of the inner diameter measuring head is indirectly adjusted, thereby comprehensively adjusting the horizontal position of the inner diameter measuring head. This allows for better fulfillment of processing requirements for various sizes and models. The inner diameter measuring head is placed close to the inner side of the bearing ring for dimensional measurement. Information is received by the sensor and transmitted to the computer for signal conversion, completing the measurement of the parts.

[0021] The position of the support frame in the Y-axis direction can be adjusted by selecting different positions of the waist groove with bolts. The sliding position of the two sets of adjustable components is fixed by clamping blocks. The size of the bearing ring is matched and measured. The rolling block contacts the side wall of the bearing ring and is combined with the rolling mechanism for overall installation and snap-fit. Attached Figure Description

[0036] This application provides an automatic bearing ring size detection mechanism, which solves the problem of compatibility in the detection of various bearing ring sizes in the prior art. The mechanism measures the size by placing the inner diameter measuring head close to the inner side of the bearing ring, and receives information through a sensor and transmits it to a computer for signal conversion, thereby completing the measurement of the part.

[0037] Example 1

[0038] The technical solution in this application embodiment is to solve the problem of compatibility in detecting various bearing ring sizes. The overall approach is as follows:

[0039] like Figure 1-3As shown, to address the problems existing in the prior art, this utility model provides an automatic bearing ring size detection mechanism, including a chassis 1. The chassis 1 consists of two sets of mutually perpendicular horizontal plates and a vertical plate. A drive mechanism 9 is provided on the back of the vertical plate, and two sets of rolling mechanisms 3 are rotatably mounted on the front of the vertical plate via bearings. The drive mechanism 9 is rotatably connected to the rolling mechanisms 3 via multiple sets of chains. A bearing ring 4 is placed on top of the rolling mechanisms 3. An upper clamping block 2 is provided on the upper inner side of the vertical plate. After the upper clamping block 2 presses down, it works in conjunction with the rolling mechanisms 3 to clamp the bearing ring 4. The drive mechanism 9 drives the rolling mechanisms 3 to rotate.

[0040] A base 5 is provided above the horizontal plate, and two sets of adjustment mechanisms 8 are provided on the upper end of the base 5. An inner diameter measuring head 6 is provided inside the adjustment mechanism 8. The inner diameter measuring head 6 is attached to the inside of the bearing ring 4 to measure the inner diameter. The other set of bearing rings 4 can also measure the outer diameter of the bearing ring 4.

[0041] like Figure 4-5 As shown, the adjustment mechanism 8 above the base 5 is symmetrically arranged in two sets, each including two sets of inner diameter measuring heads 6. This allows for measurement schemes involving two sets of inner diameters or a combination of inner and outer diameters, which can be flexibly selected according to the requirements of the bearing rings.

[0042] like Figure 6 As shown, the position of the adjustment mechanism 8 needs to be adjustable to accommodate the needs of more position measurements. The two sets of adjustment mechanisms 8 are symmetrically distributed. The following description will take one set as an example. The adjustment mechanism 8 includes a bottom fixed plate 81. The bottom fixed plate 81 is provided with a Y-axis adjustment block 85 and an X-axis adjustment block 84. The X-axis adjustment block 84 is provided with an upper fixed block 83. The upper fixed block 83 is fixedly installed with an inner diameter measuring head 6 by a clamp. The inner diameter measuring head 6 contacts the inner ring of the bearing race to adjust the inner diameter. The X-axis adjustment block 84 is a rocker mechanism in the X-axis direction, which realizes the adjustment of the upper fixed block 83 and the inner diameter measuring head 6 as a whole in the X-axis direction. The Y-axis adjustment block 85 is a rocker mechanism in the Y-axis direction. By adjusting the position of the upper X-axis adjustment block 84 in the Y-axis direction, the Y-axis direction adjustment of the inner diameter measuring head 6 is indirectly realized. The overall adjustment of the horizontal position of the inner diameter measuring head 6 is realized, so as to better meet the processing requirements of various sizes and models.

[0043] A sensor 82 is provided on the outer side of the inner diameter measuring head 6. The inner diameter measuring head 6 is pressed tightly against the inner side of the bearing ring to measure the size. The sensor 82 receives the information and transmits it to the computer for signal conversion to complete the measurement of the part.

[0044] like Figure 7-8As shown, an external measuring module 7 is bolted to the upper center of the bottom fixing plate 81. The external measuring module 7 includes a support frame 71, in which a groove is provided. The position of the support frame 71 in the Y-axis direction can be adjusted by selecting different positions of the groove through bolts. In addition, a clamping block 73 is provided at the front center of the support frame 71. The clamping block 73 has a slot in the middle, and two sets of adjustable components 72 are slidably installed. The sliding position of the two sets of adjustable components 72 is fixed by a clamping block 74 to match the measurement of the bearing ring size. A rolling block 75 is rotatably installed on the outside of the adjustable component 72. The rolling block 75 contacts the side wall of the bearing ring 4 and is connected to the rolling mechanism 3 for overall installation and clamping.

[0045] In use, the upper clamping block 2 presses down, and together with the rolling mechanism 3, the bearing ring 4 is clamped. The rolling mechanism 3 is driven to rotate by the drive mechanism 9, and the lateral external measuring module 7 provides lateral support and lateral measurement.

[0046] By adjusting the position of the upper X-axis adjustment block 84 in the Y-axis direction, the Y-axis direction of the inner diameter measuring head 6 is indirectly adjusted, thereby comprehensively adjusting the horizontal position of the inner diameter measuring head 6. This allows for better fulfillment of processing requirements for various sizes and models. The inner diameter measuring head 6 is placed close to the inner side of the bearing ring for dimensional measurement. The sensor 82 receives the information and transmits it to the computer for signal conversion, completing the measurement of the part.

[0047] The position of the support frame 71 in the Y-axis direction is adjusted by selecting different positions of the waist groove with bolts. The sliding position of the two sets of adjustable components 72 is fixed by clamping block 74. The size of the bearing ring is matched and measured. The side wall of the bearing ring 4 is contacted by rolling block 75. The whole assembly is installed and snapped together in combination with rolling mechanism 3.

[0048] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
