[0002] A micrometer screw, also known as a micrometer screw, micrometer screw, or micrometer card, is a precision tool used to measure length.

[0003] In actual production, it is necessary to measure the diameter of the reduced section of a circular cross-section tensile specimen, which is usually measured using a micrometer. When measuring, it is usually necessary to place the workpiece on the table, hold the scale frame of the micrometer with one hand, and place the workpiece between the anvil and the micrometer screw of the micrometer. Then, use the other hand to turn the adjustment knob of the micrometer so that the side screw and the anvil clamp the workpiece from both sides. At this time, read the reading of the micrometer, which is the diameter of the workpiece.

[0004] This measurement method has the following problems:

[0005] (1) It is quite strenuous for workers to hold the suspended micrometer scale frame with one hand and adjust the position of the micrometer. If a large number of workpieces are measured, the workers may suffer from arm pain.

[0006] (2) When the workpiece is placed on the table, the ruler frame needs to be as close to the table as possible. The operating space is very small and the operation is inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] In order to solve the technical problem that it is time-consuming, laborious and inconvenient to operate when measuring the diameter of a reduced section of a circular cross-section tensile specimen by a screw micrometer, the utility model provides a circular cross-section tensile specimen diameter measuring device.

[0029] See also Figure 1 , Figure 11 is a schematic structural diagram of a circular cross-section tensile specimen diameter measuring device in an embodiment of the utility model. The circular cross-section tensile specimen diameter measuring device comprises a screw micrometer 1 and a fixing mechanism 2.

[0030] See also Figure 1-Figure 3 The scale frame 11 of the micrometer screw 1 is provided with a first through hole and a second through hole. The micrometer screw 1 also includes components such as a micrometer screw 12, an anvil 13 and a knob 14. The micrometer screw 1 can be directly purchased on the market, and the structure and principle of the micrometer screw 1 are prior art, which will not be described in detail.

[0031] The fixing mechanism 2 includes a base 21, two clamps 22, a hinged portion 23 and a locking assembly 24. The two clamps 22 are fixed on the base 21 and are respectively arranged on both sides of the ruler frame 11. The two clamps 22 are each provided with a through hole 221 corresponding to the first through hole, and the two clamps 22 are also each provided with an arc groove 222 corresponding to the second through hole. The hinged portion 23 is passed through each of the through holes 221 and the first through hole, and the locking assembly 24 passes through each of the arc grooves 222 and the second through hole.

[0032] During installation, the ruler frame 11 is placed between the two clamping plates 22, the hinged portion 23 is inserted into the first through hole after passing through the through hole 221 of one clamping plate 22, and then passes through the through hole 221 of the other clamping plate 22 to realize the hinged connection between the ruler frame 11 and the two clamping plates 22, and then the inclination angle of the screw micrometer 1 is adjusted so that the screw micrometer 1 is tilted as a whole and the end close to the knob 14 is facing upward, and then the locking assembly 24 is inserted into the arc groove 222 of one clamping plate 22 after passing through the arc groove 222 of the clamping plate 22. The micrometer 1 is inserted into the second through hole and then passes through the arc groove 222 of the other clamping plate 22, and then the locking assembly 24 is locked with the clamping plate 22, so as to realize the tilt fixation of the micrometer 1; then one hand grabs the circular cross-section tensile specimen to be measured and places it against the anvil 13, and the other hand rotates the knob 14 to make the micrometer screw 12 of the micrometer 1 contact with the reduced section of the circular cross-section tensile specimen. At this time, the reading of the micrometer 1 is the diameter of the reduced section of the circular cross-section tensile specimen.

[0033] The utility model realizes the tilting and fixing of the micrometer screw 1 through the clamping plate 22, the hinged part 23 and the locking assembly 24. In this way, during operation, the worker does not need to hold the micrometer screw 1 with one hand, but can hold the circular cross-section tensile specimen with one hand. Since the weight of the circular cross-section tensile specimen is lighter than that of the micrometer screw 1, the labor intensity of the worker can be reduced, and the tilting setting of the micrometer screw 1 can facilitate the rotation of the knob 14. In addition, since the anvil 13 and the micrometer screw 12 are located at a high position, the operation space of the workpiece is large, thereby facilitating operation.

[0034] In one embodiment, see Figure 1-Figure 3 The hinge part 23 includes a fixing screw 231 and a fixing nut 232. The fixing screw 231 passes through the through hole 221 of one of the clamping plates 22 and is inserted into the first through hole, and then passes out from the through hole 221 of the other clamping plate 22. The fixing nut 232 is threadedly sleeved on the fixing screw 231 and abuts against the other clamping plate 22, so that the fixing screw 231 can be fixed to the two clamping plates 22.

[0035] In one embodiment, see Figure 1-Figure 3 The arc groove 222 is an arc groove with the first through hole as the center and the distance between the first through hole and the second through hole as the radius.

[0036] In one embodiment, see Figure 1-Figure 3 The locking assembly 24 includes a locking screw 241 and a locking nut 242. The locking screw 241 passes through the arc groove 222 of one of the clamping plates 22 and is inserted into the second through hole, and then passes out from the arc groove 222 of the other clamping plate 22. The locking nut 242 is threadedly sleeved on the locking screw 241 and abuts against the other clamping plate 22, thereby fixing the locking screw 241 and the two clamping plates 22.

[0037] In one embodiment, see Figure 1 and Figure 2 The base 21 is an iron base, and the two clamping plates 22 are both iron clamping plates, so as to increase the weight of the entire device and prevent the device from tilting when in use. The two clamping plates 22 are welded to the base 21.

[0038] In one embodiment, see Figure 1 and Figure 4 The circular cross-section tensile specimen diameter measuring device also includes a support assembly 3, one end of the support assembly 3 is fixed to the clamping plate 22, and the other end of the support assembly 3 is used to support the workpiece. The workpiece to be measured can be supported by the support assembly 3, further reducing the labor intensity of workers during measurement.

[0039] In one embodiment, see Figure 1 and Figure 4The support assembly 3 includes a fixed block 31 and a support screw 32. The fixed block 31 is fixed to the clamping plate 22. A screw hole extending in the vertical direction is opened on the fixed block 31. The support screw 32 is threadedly inserted in the screw hole. The upper end of the support screw 32 is used to support the workpiece. When in use, the height of the support screw 32 relative to the fixed block 31 can be adjusted according to the size of the workpiece. This is particularly convenient for measuring a large number of workpieces of the same type. Before testing, the support screw 32 is rotated to adjust its height so that after the workpiece is placed, its upper top surface is located on the line connecting the micrometer screw 12 and the anvil 13. When measuring later, the workpiece can be placed on the micrometer screw 12 to achieve the purpose of saving effort.

[0040] In one embodiment, see Figure 1 and Figure 4 The fixing block 31 is welded to the clamping plate 22 .

[0041] In one embodiment, see Figure 1 and Figure 4 There are two supporting assemblies 3 , which correspond to two clamping plates 22 respectively, and each fixing block 31 is fixed to the corresponding clamping plate 22 .

[0042] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail: when installing, the ruler frame 11 is placed between the two clamping plates 22, the hinged portion 23 is inserted into the first through hole after passing through the through hole 221 of one clamping plate 22, and then passes through the through hole 221 of the other clamping plate 22 to realize the hinge connection between the ruler frame 11 and the two clamping plates 22, and then the inclination angle of the screw micrometer 1 is adjusted so that the screw micrometer 1 is tilted as a whole and the end close to the knob 14 is facing upward, and then the locking assembly 24 is passed through the arc groove of one clamping plate 22. 222 is inserted into the second through hole and then passes through the arc groove 222 of the other clamping plate 22, and then the locking assembly 24 is locked with the clamping plate 22, so as to realize the tilt fixation of the micrometer screw 1; then one hand grabs the circular cross-section tensile specimen to be measured and places it against the anvil 13, and the other hand rotates the knob 14 to make the micrometer screw 12 of the micrometer screw 1 contact with the reduced section of the circular cross-section tensile specimen. At this time, the reading of the micrometer screw 1 is the diameter of the reduced section of the circular cross-section tensile specimen.

[0043] The utility model realizes the tilting and fixing of the micrometer screw 1 through the clamping plate 22, the hinged part 23 and the locking assembly 24. In this way, during operation, the worker does not need to hold the micrometer screw 1 with one hand, but can hold the circular cross-section tensile specimen with one hand. Since the weight of the circular cross-section tensile specimen is lighter than that of the micrometer screw 1, the labor intensity of the worker can be reduced, and the tilting setting of the micrometer screw 1 can facilitate the rotation of the knob 14. In addition, since the anvil 13 and the micrometer screw 12 are located at a high position, the operation space of the workpiece is large, thereby facilitating operation.

Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
