Description

Technical Field

[0001] This utility model relates to the field of measurement technology for turnout roller assemblies, specifically a turnout roller measurement fixture. Background Technology

[0002] Turnout roller assemblies are an important component of railway turnouts. They are used to lift the switch rail when it is switched, changing the original sliding friction between the bottom surface of the switch rail and the slide bed to rolling friction between the bottom surface of the switch rail and the roller assembly. This reduces switching resistance, significantly improves the safety factor of turnout switching, reduces the failure rate, and more effectively ensures the safety of high-density train operation. Therefore, quality control during the production process of turnout roller assemblies is very important. Non-standard assembly actions and lax dimensional measurement can both lead to potential quality hazards and safety accidents.

[0003] Currently, when measuring the height of roller assemblies after assembly, general measuring tools are used. The measurement results are easily affected by the workers' techniques, resulting in inaccurate results, unstable product quality, and a huge threat to railway operation safety.

[0004] Based on this, this utility model designs a turnout roller measuring fixture to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a turnout roller measuring fixture, comprising a base and a measuring assembly; the base is provided with a measuring plane for placing the roller assembly; the measuring assembly includes a height measuring unit, a column, and an installation unit, the number of height measuring units being the same as the number of rollers of different heights in the roller assembly, each height measuring unit including two height measuring elements, the height measuring elements being mounted on the measuring plane via the column, and the height measuring elements having a measuring surface for measuring the height of the rollers in the roller assembly, the two height measuring elements in the same height measuring unit being used to measure the upper limit position and lower limit position of the same roller respectively; the installation unit is used to allow the height measuring elements or the column to move parallel to the measuring plane.

[0006] As a further embodiment of this utility model, the installation unit includes a movable seat located at the bottom of the column, the bottom of which is provided with a contact plane, and the movable seat is placed on the measuring plane through the contact plane contacting the measuring plane.

[0007] As a further embodiment of this utility model, the column is rotatably mounted on a movable base around a vertical axis.

[0008] As a further embodiment of this utility model, the installation unit also includes an installation ring rotatably disposed on the column, and all height measuring components are circumferentially fixed on the installation ring.

[0014] As a further embodiment of this utility model, a stepped groove is provided at the top of the mounting base, and the stepped groove is used to accommodate the roller assembly.

[0015] This utility model has the following beneficial effects:

[0016] This fixture uses multiple height measuring elements mounted on a column. Each element has a measuring surface at its bottom.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a turnout roller measuring fixture, including a base 1 and a measuring component;

[0028] The base 1 is provided with a measuring plane 11, which is used to place the roller assembly. The measuring plane 11 is used as a reference plane. By placing the roller assembly on the measuring plane 11, the bottom position of the roller assembly is located to ensure the accuracy of subsequent measurements.

[0029] Since the parameter being measured is the height of the rollers in the roller assembly, the bottom surface of the roller assembly needs to be positioned first.

[0030] The measuring assembly includes a height measuring unit, a column 22, and an installation unit. The number of height measuring units is the same as the number of rollers of different heights in the roller assembly. Each height measuring unit includes two height measuring elements 21. The height measuring elements 21 are mounted on the measuring plane 11 via the column 22, and a height measuring surface 23 is formed on the height measuring element 21 for measuring the height of the rollers in the roller assembly. The two height measuring elements 21 in the same height measuring unit are used to measure the upper limit position and the lower limit position of the same roller, respectively. The installation unit is used to enable the height measuring element 21 or the column 22 to move parallel to the measuring plane 11.

[0031] like Figure 1As shown, the roller assembly contains two rollers, a high roller and a low roller. The high roller and the low roller have different installation heights within the roller assembly. Therefore, two height measuring units are required to measure the current roller assembly. These two height measuring units contain four height measuring elements 21, which are positioned above the measuring plane 11 via columns 22. The four height measuring elements 21 are ordered as the first height measuring element 21, the second height measuring element 21, the third height measuring element 21, and the fourth height measuring element 21, where:

[0032] The distance between the bottom measuring surface 23 of the first height measuring component 21 and the measuring plane 11 is the same as the distance from the lower limit position of the low roller to the measuring plane 11;

[0033] The distance between the bottom measuring surface 23 of the second height measuring component 21 and the measuring plane 11 is the same as the distance from the upper limit position of the low roller to the measuring plane 11;

[0034] The distance between the bottom measuring surface 23 of the third height measuring component 21 and the measuring plane 11 is the same as the distance from the lower limit position of the high roller to the measuring plane 11;

[0035] The distance between the bottom measuring surface 23 of the fourth height measuring component 21 and the measuring plane 11 is the same as the distance from the upper limit position of the high roller to the measuring plane 11;

[0036] Since the height measuring component 21 and / or the column 22 can move parallel to the measuring plane 11, the height measuring surface 23 at the bottom of the height measuring component 21 can be moved closer to the high roller and the low roller by moving the height measuring component 21 or the column 22. The first and second height measuring components 21 are then moved closer to the low roller. When the height measuring surface 23 at the bottom of the first height measuring component 21 cannot pass over the top of the low roller, it indicates that the installation height of the low roller is not below the lower limit position. When the height measuring surface 23 at the bottom of the second height measuring component 21... When 23 can pass smoothly over the top of the low roller, it means that the installation height of the low roller has not exceeded the upper limit position. Similarly, by approaching the high roller with the third and fourth height measuring components 21 respectively, when the bottom measuring surface 23 of the third height measuring component 21 cannot pass over the top of the low roller, it means that the installation height of the high roller is not lower than the lower limit position. When the bottom measuring surface 23 of the fourth height measuring component 21 can pass smoothly over the top of the high roller, it means that the installation height of the high roller has not exceeded the upper limit position.

[0037] When the bottom measuring surface 23 of the first measuring element 21 can pass through the top of the low roller, it means that the installation position of the low roller is lower than the lower limit position. When the bottom measuring surface 23 of the second measuring element 21 cannot pass through the top of the low roller, it means that the installation position of the low roller is higher than the upper limit position. When the bottom measuring surface 23 of the third measuring element 21 can pass through the top of the high roller, it means that the installation position of the high roller is lower than the lower limit position. When the bottom measuring surface 23 of the fourth measuring element 21 cannot pass through the top of the high roller, it means that the installation position of the high roller is higher than the upper limit position.

[0038] The upper and lower limit positions of the low roller and the high roller are detected by the measuring surfaces 23 at the bottom of the first, second, third, and fourth height measuring components 21, respectively. This enables rapid inspection of the installation height of the low roller and the high roller without moving or flipping the roller assembly. It can also inspect the assembly accuracy and does not require high operator skill, thus improving product quality and production efficiency.

[0039] like Figure 1 As shown, the installation unit includes a movable seat 24 fixed to the bottom of the column 22. The bottom of the movable seat 24 is provided with a contact plane. The movable seat 24 is placed on the measuring plane 11 through the contact plane. The contact plane is used to position the distance between the height measuring component 21 on the column 22 and the measuring plane 11. At the same time, the column 22 is placed on the measuring plane 11 through the movable seat 24, so that the column 22 can slide freely on the measuring plane 11, so that the height measuring component 21 can pass over the roller in the roller assembly.

[0040] By fixing a movable base 1 at the bottom of the column 22 and placing the movable base 1 directly on the measuring plane 11, the column 22 can be stably placed on the measuring plane 11. At the same time, the movable base 1 can be moved or rotated freely to achieve parallel movement of the column 22 and the height measuring component 21. A contact plane is provided at the bottom of the movable base 1. When the contact plane and the measuring plane 11 are processed, there are higher flatness requirements. When the movable base 1 is placed on the measuring plane 11, the contact plane contacts the measuring plane 11, which can improve the accuracy of the position of the height measuring surface 23 and improve the accuracy of the detection.

[0041] like Figure 1 As shown, all the height measuring components 21 are arranged at intervals along the circumference on the column 22. By rotating the column 22, different height measuring components 21 can be moved in parallel to the top of the roller in the roller assembly to detect the height of the roller. By setting all the height measuring components 21 on one column 22, the integration of the overall measuring fixture is improved. During use, there is no need to frequently switch between different columns 22, making it simpler and more convenient to use.

[0042] Furthermore, the height measuring elements 21 used to measure the same roller are arranged adjacent to each other. This way, after measuring the upper limit position of a roller through the height measuring element 21, the roller can continue to rotate and measure the lower limit position of the roller through the height measuring element 21. This prevents the height measuring elements 21 used to measure other rollers from interfering with the rollers during rotation, making it more convenient to use.

[0043] Furthermore, the surface of the height measuring component 21 is provided with markings 26 for distinguishing the heights of different height measuring surfaces 23. Since the height difference between the bottom height measuring surfaces 23 of different height measuring components 21 is difficult to distinguish with the naked eye, it is necessary to set markings 26 on the surface of the height measuring component 21 to facilitate the distinction of different height measuring surfaces 23 during use.

[0044] like Figure 2 As shown, the top surface of the movable seat 24 is provided with a rotating groove, and the bottom end of the column 22 is rotatably set in the rotating groove.

[0045] By rotatably mounting the column 22 onto the movable base 24, the column 22 can rotate on the movable base 24. When it is necessary to move the height measuring component 21, rotating the column 22 can move the height measuring component 21 parallel to the measuring plane 11 without having to rotate the movable base 24, making it more convenient to use. This also reduces wear on the measuring plane 11 and the contact plane. Furthermore, rotatably mounting the column 22 onto the movable base 24 ensures the stability of the column 22 during rotation. When the movable base 24 is rotated directly, since the movable base 24 itself has no limit and there is friction between the contact plane and the measuring plane 11, it is difficult to ensure the stability of the movable base 24. This further increases the accuracy of the measurement.

[0046] like Figure 3 As shown, in some examples, the mounting unit also includes a mounting ring 25 rotatably mounted on the column 22, and several height measuring components 21 are circumferentially fixed on the mounting ring 25.

[0047] By rotating the mounting ring 25 on the column 22 and then installing all the height measuring components 21 circumferentially on the outer side of the mounting ring 25, when it is necessary to move the height measuring component 21, the mounting ring 25 can be rotated directly to make the height measuring component 21 move parallel to the measuring plane 11, making the movement more convenient. At the same time, it can ensure the stability of the height measuring component 21 during movement and improve the measurement accuracy.

[0048] like Figure 4 As shown, in some examples, the height of the height measuring component 21 on the column 22 is adjustable;

[0049] like Figure 4As shown, the column 22 is a cylinder, and an adjusting ring 27 is threaded onto the column 22. The height measuring component 21 is fixedly installed on the adjusting ring 27. By rotating the adjusting ring 27, the height of the adjusting ring 27 on the column 22 can be changed, thereby achieving the effect of adjusting the height of the height measuring component 21 on the column 22 to adapt to the measurement of different types of roller assemblies.

[0050] like Figure 5 As shown, two mounting seats 3 are fixedly installed on the base 1, and the two mounting seats 3 are spaced apart. The roller assembly is placed on the top of the two mounting seats 3 so that the bottom of the roller assembly forms an operating space between it and the measuring plane 11.

[0051] like Figure 1 As shown, when assembling the roller assembly, a fixing bolt needs to be inserted through the roller assembly, and the roller assembly is fixed by engaging the fixing bolt with a nut at the bottom end of the roller assembly. The roller assembly can be supported by two mounting seats 3, so that the bottom end of the roller assembly can be suspended in the air when assembling the roller assembly, forming an operating space between the roller assembly and the measuring plane 11, which facilitates the operator to assemble the roller assembly, and at the same time facilitates the observation of the bottom of the roller assembly during assembly.

[0052] Furthermore, such as Figure 5 As shown, a stepped groove 31 is provided at the top of the mounting base 3. The openings of the stepped grooves 31 on the two mounting bases 3 are opposite each other, and the distance between the vertical walls of the two stepped grooves 31 matches the width or length of the roller assembly, so that the roller assembly can be just locked in the two stepped grooves 31 to limit the horizontal movement of the roller assembly and improve the stability of the roller assembly during assembly and measurement.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
