Abstract
Description
Technical Field
[0001] The utility model relates to a caliper for measuring the size of special-shaped steel parts in a high-temperature state, belonging to the technical field of steel measuring tools. Background Art
[0002] In steel production, it is often necessary to measure the external dimensions of steel. General measuring tools include calipers, straightedges, micrometers, calipers, etc. However, the data measured by calipers and straightedges are not accurate enough to meet the measurement needs of many steels. Using a micrometer is not suitable for on-line measurement of high-temperature steel. Only calipers can meet the measurement needs of most steels in terms of measurement accuracy, and calipers can also measure high-temperature steel on-site. However, in the actual production process, many steel parts are special-shaped parts, and it is difficult for general calipers to measure some parts of the steel parts, which brings inconvenience to the measurement work and affects the production efficiency. Therefore, it is very necessary to improve the existing measuring tools to meet the needs of on-site production work. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a caliper for measuring the cross-section of high-temperature special-shaped steel parts. This caliper can be unaffected by high temperature, measure the cross-section of special-shaped steel parts in the range of 500-1000°C at high temperature, and at the same time can avoid the obstructive parts of the special-shaped steel parts and accurately measure the parts of the special-shaped steel parts that need to be measured.
[0004] The technical solution to solve the above technical problem is as follows:
[0005] A caliper for measuring the cross-section of high-temperature special-shaped steel parts, which is composed of a fixed jaw, a ruler body, a vernier seat, a vernier, a movable jaw, and a locking nut. The fixed jaw is connected to the front end of the ruler body. The vernier seat and the vernier are respectively located above and below the ruler body. The vernier seat is connected to the ruler body through the locking nut. The vernier is opposite to the lower edge of the ruler body. The improvement is that the movable jaw is L-shaped. The L-shape of the movable jaw is composed of a connecting rod and a measuring rod. The upper end of the connecting rod is vertically connected to the rear end of the vernier, and the lower end of the connecting rod is vertically connected to the rear end of the measuring rod. The measuring rod is parallel to the vernier. The front end of the measuring rod is opposite to the edge of the notch of the fixed jaw. The gap between the fixed jaw and the connecting rod of the movable jaw is for measuring special-shaped steel parts.
[0006] For the above caliper for measuring the cross-section of high-temperature special-shaped steel parts, unit scales are marked on the vernier. When the zero position of the vernier seat is opposite to the zero position of the vernier, the edge of the notch of the fixed jaw is in close contact with the front end of the measuring rod of the movable jaw. A gasket is installed between the locking nut side of the vernier seat and the vernier.
[0007] The beneficial effects of the utility model are:
[0008] The utility model adopts the structure of a general vernier caliper, and the movable jaw is changed to an L shape. The front end of the measuring rod of the movable jaw can cooperate with the fixed jaw to measure the cross-section of a special-shaped steel part that needs to be measured. There is a gap between the connecting rod of the movable jaw and the fixed jaw, and the part of the special-shaped steel part that hinders the measurement can be accommodated in this gap, making the measurement accurate and convenient.
[0009] The utility model has a simple structure and is easy to use. It can avoid the obstructive part of the special-shaped steel part and accurately measure the part that needs to be measured of the special-shaped steel part. During the measurement process, it is not affected by high temperature and can measure the cross-section of special-shaped steel parts at high temperatures in the range of 500 - 1000 °C, meeting the measurement needs of the production site. Description of the Drawings
[0010] Figure 1 is a schematic structural diagram of the utility model;
[0011] Figure 2 is a schematic diagram of the measurement positions of several special-shaped steel parts with different structures.
[0012] The markings in the figure are as follows: fixed jaw 1, body of the caliper 2, vernier seat 3, vernier 4, movable jaw 5, locking nut 6, connecting rod 7, measuring rod 8, special-shaped steel part 9, measurement part 10. Detailed Implementation Manner
[0013] The utility model is composed of a fixed jaw 1, a body of the caliper 2, a vernier seat 3, a vernier 4, a movable jaw 5, and a locking nut 6.
[0014] Figure 1 It shows that the fixed jaw 1 is connected to the front end of the body of the caliper 2. The vernier seat 3 and the vernier 4 are respectively located above and below the body of the caliper 2. The vernier seat 3 is connected to the body of the caliper 2 through the locking nut 6. The vernier 4 is opposite to the lower edge of the body of the caliper 2, and unit scales are marked on the vernier 4. The movable jaw 5 is connected to the lower part of the vernier 4. By moving the vernier 4, the movable jaw 5 and the fixed jaw 1 can measure the special-shaped steel part 9.
[0015] Figure 1 It shows that in order to measure the special-shaped steel part 9, the movable jaw 5 has been improved.
[0016] The improved movable jaw 5 is in an L shape. The L shape of the movable jaw 5 is composed of a connecting rod 7 and a measuring rod 8, and the connecting rod 7 and the measuring rod 8 are perpendicularly connected to form an L shape. The upper end of the connecting rod 7 is perpendicularly connected to the rear end of the vernier 4, the lower end of the connecting rod 7 is perpendicularly connected to the rear end of the measuring rod 8, the measuring rod 8 is parallel to the vernier 4, and the front end of the measuring rod 8 is opposite to the edge of the bayonet of the fixed jaw 1. There is a gap between the fixed jaw 1 and the connecting rod 7 of the movable jaw 5. When measuring the special-shaped steel part 9, the part of the special-shaped steel part 9 that hinders the measurement can be placed in this gap without affecting the measurement.
[0017] Figure 1 It shows that when the zero position of the vernier seat 3 is opposite to the zero position of the vernier 4, the clamping edge of the fixed jaw 1 is in close contact with the front end of the measuring rod 8 of the movable jaw 5. When the vernier 4 is pulled apart, the distance between the front end of the measuring rod 8 of the movable jaw 5 and the clamping edge of the fixed jaw 1 can be displayed on the vernier seat 3, ensuring the accuracy during measurement.
[0018] After adopting this structure, the present utility model can realize the on-line measurement of various profiled steel sections, parts, etc., and calipers with different ranges can be configured according to the size of the rolled piece, so as to accurately read the measurement value.
[0019] When using the present utility model, first separate the scale body 2 from the vernier 4, then clamp the part of the profiled steel piece 9 to be measured with the fixed jaw 1, and then slide the vernier 4 to make the front end of the measuring rod 8 of the movable jaw 5 contact the profiled steel piece 9. The scale indicated by the zero position of the vernier 4 on the scale body 2 is the value of the measured part. This measurement method is both convenient and practical, and can on-line measure the sizes of profiled steel sections, parts, etc. at high temperatures in the range of 500 - 1000 °C.
