Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bogie fixed lever fulcrum seat angle measurement, especially the field of K6 type bogie fixed lever fulcrum seat angle measurement. BACKGROUND

[0002] The K6 type bogie is an improved bogie designed by China railway to adapt to heavy load transportation (axle load 25t), and the brake system thereof optimizes the lever angle and structural strength on the basis of K5, thereby improving brake stability and component life. The fixed lever fulcrum seat is installed on a bolster and connected with a fulcrum, and a 50° included angle design is used to ensure that the included angle between the brake lever and the longitudinal vertical plane of the vehicle body is 50°. The brake lever is an important component of the bogie basic brake device, and the 50° included angle design of the brake lever allows the longitudinal brake force generated by the brake cylinder to be decomposed into two directional components, the longitudinal component is transmitted along the longitudinal direction of the vehicle body and directly acts on the brake shoe to form a clamping force on the wheel, and the transverse component is offset through the structure of the bogie (such as the fixed fulcrum) to avoid additional stress on the lever system due to the transverse force.

[0003] The existing detection method has the following main problems:

[0004] (1) The three-coordinate measurement is low in efficiency and high in cost;

[0005] (2) The measurement reference of the general gauge (universal angle gauge, etc.) is difficult to accurately position;

[0006] (3) The manual interpretation error is large;

[0007] (4) The on-site rapid detection requirement is difficult to meet. INVENTION CONTENTS

[0008] The utility model solves the technical problem of providing a measurement tool for the angle of the fixed lever fulcrum seat of the K6 type bogie, which can conveniently, quickly and accurately measure.

[0009] The utility model adopts the technical scheme: a K6 type bogie fixed lever fulcrum seat angle measurement sample board is a plate-shaped structure, and the front and back of the board are plate surfaces (the area of the front and back is much larger than that of the other surfaces), which comprises a planar bottom surface 4 and a measurement surface 1 at a 50° included angle with the bottom surface 4 at the measurement end.

[0010] The upper side of the measurement surface 1 of the sample board has an upper notch 3, and the lower side of the measurement surface 1 of the sample board has a lower notch 2.

[0011] The thickness of the sample board is uniform, and the thickness is 0.5-1cm.

[0012] The upper and lower bottom surfaces of the sample plate are parallel, the measuring end measuring surface 1 of the sample plate is a rectangular surface, the upper cutout 3 of the sample plate is a rectangular surface, and the lower cut groove 2 of the sample plate is a cuboid groove.

[0013] The sample plate is made of a metal material which is wear-resistant, high in strength and not easy to deform, has an irregular shape as a whole, and has a specific bevel structure, and the bevel angle is accurately set to 50° (included angle with the horizontal plane).

[0014] The length of the measuring end measuring surface 1 of the sample plate is 1 / 2-2 / 3 of the width of the measured surface of the K6 type bogie fixed lever fulcrum seat.

[0015] The use method is as follows: the K6 type bogie fixed lever fulcrum seat is placed on a horizontal platform, and before measurement, the 50° angle surface to be measured of the K6 type bogie fixed lever fulcrum seat is tightly attached to the horizontal platform surface to keep horizontal, then the measuring surface of the utility model is attached to the actual measured surface to be measured of the K6 type bogie fixed lever fulcrum seat, the attachment of the measuring surface and the actual measured surface to be measured is observed, if the two surfaces are completely coincident or the gap is within the allowable error range, the angle is qualified. If there is a gap, the angle deviation value can be further measured and converted by using a plug gauge or the like.

[0016] The utility model has the advantages that the utility model can conveniently, quickly and accurately measure the angle of the K6 type bogie fixed lever fulcrum seat. BRIEF DESCRIPTION OF DRAWINGS

[0023] The utility model of the fixed lever fulcrum seat angle measuring template of the K6 type bogie is prepared on the basis of a cuboid plate. One end of a cuboid plate with a thickness of 0.8cm, a length of 60cm, and a width of 20cm (in this embodiment, the left end with a cross-section of 1mm*20mm) is used as the measuring end, and a 1cm*60cm face is used as the bottom surface 1.

[0024] like Figure 4 As shown, the initial structure is completed simply by cutting a 50-degree angled bevel at the measuring end.

[0025] Figure 2 This is a schematic diagram of the fixed lever fulcrum seat structure of the K6 type bogie. The fixed lever fulcrum seat of the K6 type bogie is installed on the bolster and connected to the fulcrum. Its 50° included angle surface design is to ensure that the included angle between the brake lever and the longitudinal vertical plane of the car body is 50°.

[0026] Figure 3 This is a schematic diagram of the measurement process for this utility model. During the measurement, the fixed lever fulcrum seat of the K6 bogie is placed on a horizontal platform. Before measurement, ensure that the 50° angle surface of the fixed lever fulcrum seat to be measured is in close contact with the horizontal platform surface and remains horizontal. Then, align the measuring surface of this utility model with the actual measuring surface of the fixed lever fulcrum seat of the K6 bogie and observe the fit between them. If they completely overlap or the gap is within the allowable error range, the angle is qualified. If there is a gap, it can be further measured using feeler gauges or other tools, and the angle deviation value can be calculated.

[0027] This utility model can be used in Figure 4 Optimize based on, such as Figure 5 As shown, in order to more clearly observe the fit between the measuring surface and the actual measured surface, an upper cut 3 is made on the upper side of the measuring surface 1 of the template, and a lower cut groove 2 is made on the lower side of the measuring surface 1 of the template. This facilitates observation, and the upper cut 3 and lower cut groove 2 can also prevent contact with other surfaces of the actual measured surface 6 of the K6 type bogie fixed lever support seat, thus preventing the measurement from being affected.

[0028] This utility model can be used in Figure 5 Further optimization based on existing models, taking into account both visual appeal and aesthetics, such as... Figure 1 As shown, the top and bottom surfaces of the template are parallel, the measuring end 1 of the template is a rectangular surface, the upper cut 3 of the template is a rectangular surface, and the lower cut 2 of the template is a cuboid groove.

[0029] The device of this invention has the following advantages in the testing process of a fixed lever fulcrum seat:

[0030] 1. Measuring efficiency: Compared with traditional measuring tools, the template can be directly fitted and compared with the measured part without complex operation and calculation, greatly shortening the measuring time and improving the detection work efficiency.

[0031] 2. Measuring accuracy: The 50° angle surface of the K6 type bogie fixed lever fulcrum seat of the template is precisely machined and calibrated, which can intuitively and accurately reflect the measured angle deviation during measurement, effectively improve the measurement accuracy, and ensure the installation and use performance of the related parts of the bogie.

[0032] 3. Operation convenience: The template is designed to be lightweight, easy to carry and use on site, simple structure and easy to operate by hand.
