Description
Technical Field
The utility model relates to a machine-building technical field belongs to the detection device of machine parts, in particular to curved surface track web measuring device.
Background
The thickness of the web as the curved track has certain dimensional requirements in the using process, and the excessive or insufficient dimension is not allowed. The web is deformed when being changed from a straight line to a bent line during the manufacturing process, and the thickness of the web is changed (locally thickened or thinned) due to abrasion, extrusion and the like during the use process. The existing practical situation cannot avoid the two situations. This requires the web of the rail to be measured to ensure that it is within the dimensions allowed by the design, or else to be refurbished or replaced.
Because the size of the curved track is generally large and some moving parts need to move around, the existing general measurement cannot be directly measured by other devices except a large-scale articulated three-coordinate measuring machine, and only an indirect measurement method is adopted. The reference point which can be used for indirect measurement is generally far, the error is large, and the measurement precision is difficult to guarantee. Therefore, a device capable of direct measurement and achieving the measurement accuracy required by use is needed to replace the traditional indirect measurement.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the technical problem that exists among the known art and provide curved surface track web measuring device, solve the orbital web thickness of curved surface and can only take indirect measurement's problem.
The utility model comprises the following technical scheme: the curved surface track web measuring device is used for measuring the thickness of the web of the curved surface track, and is characterized in that the device is arranged on a vernier caliper, and the thickness of a measured section bar is calculated by means of the reading of the vernier caliper; the device comprises a U-shaped main body, a fixing part and a measuring part, wherein the fixing part and the measuring part are respectively fixed at two ends of the U-shaped main body; a groove is formed in the fixing part, a vernier caliper is installed in the groove, and a depth gauge is arranged at the tail part of the vernier caliper; and a part to be measured of the measured section bar is arranged between the depth gauge and the measuring part.
Preferably, one end of the measuring part positioned on the measured section bar is a tip, so that a point to be measured is positioned conveniently.
Preferably, the size of the device is determined according to the bending radius of the bending surface of the measured profile and the size of the measured profile.
Preferably, the tested section bars can be angle steel, channel steel, I-shaped steel, H-shaped steel, Z-shaped steel and the like.
The utility model has the advantages and positive effect:
1. the utility model discloses the cost is less than the best articulated type three-coordinate measuring apparatu at present far away.
2. The utility model discloses do not need power, manual operation can.
3. The utility model is simple in operation, as long as carry out simple training, general ordinary workman can operate.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-measured profile; 2-depth gauge; 3-a measuring section; a 4-U shaped body; 5-a fixed part; 6-vernier caliper.
Detailed Description
To further disclose the contents, features and functions of the present invention, the following examples are given in detail with reference to the accompanying drawings.
Example (b): referring to the attached figure 1, the curved surface track web measuring device is used for measuring the thickness of a web of a curved surface track, a measured section bar is 1I-shaped steel, the size of the I-shaped steel is 150 x 150, the device is installed on a vernier caliper 6, and the thickness of the measured section bar 1 is calculated by means of the reading of the vernier caliper 6; the device comprises a U-shaped main body 4, a fixing part 5 and a measuring part 3, wherein the fixing part 5 and the measuring part 3 are respectively fixed at two ends of the U-shaped main body 4; a groove is formed in the fixing part 5, a vernier caliper 6 is installed in the groove, a depth gauge 2 is arranged at the tail of the vernier caliper 6, and the depth gauge 2 is used for assisting the measuring part 3 to position the measured section bar 1; and a part to be measured of the measured section bar 1 is arranged between the depth gauge 2 and the measuring part 3. One end of the measuring part 3 positioned on the measured section bar 1 is a tip, so that a point to be measured can be conveniently positioned. The size of the device is determined according to the bending radius of the bending surface of the tested section bar 1 and the size of the tested section bar.
The working principle is as follows: the measuring device directly measures by means of the vernier caliper which is identified to meet the use standard, and reads data on the vernier caliper, wherein the precision of the data is the precision of the vernier caliper, so that the measuring precision is ensured. Local thinning or thickening on the curved surface track web can be measured, and when the measuring device is used, the fixing head needs to be perpendicular to a measured part so as to avoid distorting measured data.
Although the preferred embodiments of the present invention have been described, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention. All of which fall within the scope of the present invention.
