Description

Technical Field

[0001] The invention relates to the technical field of red-cover gauge measurement, in particular to a universal red-cover gauge measurement tool. Background Art

[0002] A gauge is an entity with accurate size and shape, usually used to measure, inspect or calibrate the size, shape or position of an object. It has a simple structure and can be in the form of a cone, cylinder, block plate, ruler, threaded part, etc. Gauges can be divided into: smooth cylindrical limit gauges, cone gauges, position gauges and working gauges, etc. In the red sleeve, also known as the red sleeve interference fit, also known as the hot fit method, is a method of assembly using the physical properties of thermal expansion and contraction of metal materials. The red sleeve gauge can be used to measure the size of holes after the heavy-load structure is heated.

[0003] Common universal red-set gauge measuring tools are usually composed of a main scale, a vernier, a base, and fixing and adjusting screws. Scale lines are added to the main scale and the vernier, and the vernier can be moved on the surface of the main scale. When it is aligned with the heavy-load structure hole, the vernier is moved to measure the hole size. This is the common structure and usage of universal red-set gauge measuring tools. Traditional universal red-set gauge measuring tools have the problem of manufacturing waste materials and multiple placement in many scenarios, which leads to increased material waste costs and inconvenience in storage and use. For this reason, a universal red-set gauge measuring tool is proposed. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a universal red sleeve gauge measuring tool to solve the above-mentioned technical problems of material waste, increased costs, and inconvenience in storage and use.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a universal red cover gauge measuring tool, comprising:

[0008] a gauge bar, and a handle disposed directly below the bottom center of the gauge bar;

[0009] The thread groove is arranged at the top center of the gauge crossbar, and the inner wall of the thread groove is provided with an internal thread;

[0010] The threaded column is arranged at the bottom center of the handle, and the outer surface of the threaded column is provided with an external thread, and the thread groove matches the thread between the threaded column. By threading the thread groove of the gauge crossbar and the threaded column of the handle, the handle can be used to drive the gauge crossbar to measure the size of the heated heavy-load structure. On the one hand, it can ensure the purpose of tight connection with a set of gauge crossbars of different lengths. At the same time, the length and diameter of the gauge crossbar can be changed as needed to save manufacturing materials and facilitate storage and use; on the other hand, the two ends of the gauge crossbar are smooth spherical, which can ensure the strength of use and prevent cracks, bending, breakage, etc. during use.

[0011] Preferably, a hollow groove is longitudinally opened in the center of the lower part of the inner cavity of the handle, and a slide groove is longitudinally opened in the center of the lower part of the front and back sides of the handle and communicates with the hollow groove. The hollow groove can be connected to the slide groove and the corresponding structure.

[0012] Preferably, an annular plate is added to the upper center of the inner cavity of the hollow groove, and an inlet and outlet hole is opened at the top center of the annular plate, and a limiting hole is opened at the front and rear centers of the inner wall of the inlet and outlet hole. Positioning grooves are longitudinally opened at the centers of both sides of the top of the inlet and outlet hole, and the shapes are consistent with the limiting holes. The corresponding structure can rise to the top of the annular plate through the inlet and outlet hole and the limiting hole, rotate, and fit tightly with the positioning groove.

[0013] Preferably, a pressure plate is installed at the center of the front and rear ends of the top of the annular plate, and the outer ends of the pressure plates extend outward through corresponding slide grooves. The pressure plate can drive the annular plate to descend along the slide groove, separate the corresponding structure from the positioning groove, and reset and rotate, and then descend through the entry and exit holes and the limit holes to separate from the annular plate.

[0014] Preferably, guide posts are inserted at the centers of both sides of the top of the annular plate, and the bottom ends of the guide posts are connected to the inner wall of the hollow groove. The surfaces of the guide posts are sleeved with extrusion springs, and the top ends of the extrusion springs fit in with the bottom of the annular plate. The annular plate is held on the upper surface of the guide posts by the extrusion springs, so that the corresponding structure is connected to the positioning groove by a clamping connection, thereby preventing the corresponding structure from rotating on the top of the annular plate and self-separation.

[0015] Preferably, a connecting column is installed on the top of the threaded column, and the connecting column corresponds to the entry and exit hole, and limiting plates are installed on the upper parts of the two sides of the surface of the connecting column, and correspond to the limiting holes and the positioning grooves. The connecting column on the threaded column and the connecting column rise to the top of the annular plate through the entry and exit holes and the limiting plates, and the bottom of the limiting plate is connected with the positioning groove, and the annular plate can be driven down along the slide groove by the pressing plate, and the limiting plate and the positioning groove are separated, and reset and rotated, and then descended through the entry and exit holes and the limiting holes to separate from the annular plate. On the one hand, since the threaded column needs to be threadedly connected and is in the outside world, it is easy to cause thread distortion when a collision occurs, resulting in the inability to use the threaded connection. The threaded column can be replaced separately, and the handle cannot be replaced as a whole, which not only saves manufacturing materials, but also reduces the cost of use; on the other hand, not only does it not change much in the overall weight of the handle, but it is also convenient for the disassembly and assembly of the handle and the threaded column.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a universal red sleeve gauge measuring tool, which has the following beneficial effects:

[0018] 1. This universal red-covered gauge measuring tool, after threading the thread groove of the gauge cross bar with the thread column of the handle, can use the handle to drive the gauge cross bar to measure the size of the hole after the heavy-load structure is heated. In this way, on the one hand, it can ensure the purpose of tight connection with a set of gauge cross bars of different lengths, and at the same time, the length and diameter of the gauge cross bar can be changed as needed to save manufacturing materials and facilitate storage and use; on the other hand, the two ends of the gauge cross bar are smooth spherical, which can ensure the strength of use and prevent cracks, bending, breakage, etc. during use.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides a technical solution, a universal red sleeve gauge measuring tool, comprising: Figure 1 , a gauge cross bar 1, and a handle 3 arranged just below the bottom center of the gauge cross bar 1;

[0026] The thread groove 2 is arranged at the top center of the gauge cross bar 1, and the inner wall of the thread groove 2 is provided with an internal thread;

[0027] The threaded column 4 is arranged at the bottom center of the handle 3, and the outer surface of the threaded column 4 is provided with an external thread, and the thread between the thread groove 2 and the threaded column 4 matches. By threading the thread groove 2 of the gauge crossbar 1 and the threaded column 4 of the handle 3, the handle 3 can be used to drive the gauge crossbar 1 to measure the size of the heated heavy-load structure. On the one hand, it can ensure the purpose of tight connection with the gauge crossbar 1 of different lengths. At the same time, the length and diameter of the gauge crossbar 1 can be changed as needed to save manufacturing materials and facilitate storage and use; on the other hand, the two ends of the gauge crossbar 1 are smooth spherical, which can ensure the strength of use and prevent cracks, bending, breakage, etc. during use.

[0028] See also Figure 2 A hollow groove 5 is longitudinally provided at the center of the lower part of the inner cavity of the handle 3, and a slide groove 6 is longitudinally provided at the center of the lower part of the front and back sides of the handle 3 and is connected to the hollow groove 5. The hollow groove 5 can be connected to the slide groove 6 and the corresponding structure.

[0029] See also Figure 3, an annular plate 7 is added to the upper center of the inner cavity of the hollow groove 5, and an inlet and outlet hole 8 is opened at the top center of the annular plate 7, and a limiting hole 9 is opened at the front and rear centers of the inner wall of the inlet and outlet hole 8. Positioning grooves 10 are longitudinally opened at the centers of both sides of the top of the inlet and outlet hole 8, and the shapes are consistent with the limiting holes 9. The corresponding structure can rise to the top of the annular plate 7 and rotate through the inlet and outlet hole 8 and the limiting hole 9, and fit tightly with the positioning groove 10. Pressing plates 11 are installed at the center positions of the front and rear ends of the top of the annular plate 7, and the outer ends of the pressing plates 11 extend outward through the corresponding slide grooves 6. The annular plate 7 can be driven down along the slide groove 6 by the pressing plate 11, and the corresponding structure is separated from the positioning groove 10, and reset and rotated, and then descended through the inlet and outlet hole 8 and the limiting hole 9 to separate from the annular plate 7. Guide posts 12 are inserted at the centers of both sides of the top of the annular plate 7, and the bottom ends of the guide posts 12 are connected to the inner wall of the hollow groove 5. Extrusion springs 13 are sleeved on the surfaces of the guide posts 12, and the top ends of the extrusion springs 13 fit in with the bottom of the annular plate 7. The annular plate 7 is held on the upper surface of the guide posts 12 by the extrusion springs 13, so that the corresponding structure is connected to the positioning groove 10 by a clamping connection, thereby preventing the corresponding structure from rotating on the top of the annular plate 7 and self-separation.

[0030] See also Figure 4 , a connecting column 14 is installed on the top of the threaded column 4, and the connecting column 14 corresponds to the inlet and outlet hole 8, and a limiting plate 15 is installed on the upper part of the surface of the connecting column 14 on both sides, and corresponds to the limiting hole 9 and the positioning groove 10. The connecting column 14 on the threaded column 4 and the connecting column 14 rise to the top of the annular plate 7 through the inlet and outlet hole 8 and the limiting plate 15 to rotate, and the bottom of the limiting plate 15 is connected with the positioning groove 10, and the annular plate 7 can be driven down along the slide groove 6 through the pressing plate 11, and the limiting plate 15 is separated from the positioning groove 10, and reset and rotated, and then descended through the inlet and outlet hole 8 and the limiting hole 9 to separate from the annular plate 7. On the one hand, since the threaded column 4 needs to be threadedly connected and is in the outside world, it is easy to cause thread distortion and other phenomena when a collision occurs, resulting in the inability to use the threaded connection. The threaded column 4 can be replaced separately, and the handle 3 cannot be replaced as a whole, which not only saves manufacturing materials, but also reduces the cost of use; on the other hand, it not only makes the overall weight of the handle 3 not change much, but also facilitates the disassembly and assembly operation between the handle 3 and the threaded column 4.

[0031] This solution: By threading the thread groove 2 of the gauge crossbar 1 and the thread column 4 of the handle 3, the handle 3 can be used to drive the gauge crossbar 1 to measure the size of the heated heavy-load structure. The connecting column 14 on the thread column 4 and the connecting column 14 rise to the top of the annular plate 7 through the entry and exit hole 8 and the limit plate 15 and rotate. The bottom of the limit plate 15 is connected with the positioning groove 10. The annular plate 7 can be driven down along the slide groove 6 by the pressing plate 11. The limit plate 15 is separated from the positioning groove 10, and reset and rotated, and then descended through the entry and exit hole 8 and the limit hole 9 to separate from the annular plate 7.
