At present, there are electronic instruments for measuring threads on the market, such as thread measuring instruments. Although they have the advantages of simple operation and high accuracy, they are expensive and are not suitable for assembly lines.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1

[0026] Please see attached Figure 1-4 , a new type of easy-to-use thread gauge, including:

[0027] A cylindrical shell 1, a pressing handle 2, a rotating component 3 and a go / no-go gauge end 4, wherein the rotating component 3 is movably connected inside the cylindrical shell 1, the pressing handle 2 passes through the upper side wall of the cylindrical shell 1 and is movably connected to the upper end of the rotating component 3, and the pressing handle 2 is slidably connected to the cylindrical shell 1, and the go / no-go gauge end 4 is detachably connected to the lower end of the rotating component 3.

[0028] Specifically, the rotating assembly 3 includes an upper connecting disc 30, a spiral rod 31, a spring 32, a penetrating disc 33 and a length compensation assembly 34, wherein the penetrating disc 33 is fixedly connected to the middle position of the inner wall of the cylindrical shell 1, and a penetrating hole 330 matching the spiral rod 31 is provided on the penetrating disc 33, the upper connecting disc 30 is rotatably connected to the lower end of the pressing handle 2, the upper end of the spiral rod 31 is fixedly connected to the upper connecting disc 30, and the lower end is fixedly connected to the length compensation assembly 34 after passing through the spring 32 and the penetrating hole 330, the two ends of the spring 32 are respectively fixedly connected to the upper connecting disc 30 and the penetrating disc 33, the length compensation assembly 34 passes through the bottom wall of the cylindrical shell 1 and is slidably connected thereto, and the go / no-go gauge end 4 is detachably connected to the length compensation assembly 34;

[0029] When in use, when holding the cylindrical shell 1 and pressing the pressing handle 2 downward, the pressing handle 2 drives the upper connecting disc 30 and the screw rod 31 to move downward. In the process of the screw rod 31 moving downward and passing through the penetration hole 330, since the penetration disc 33 is fixedly connected to the cylindrical shell 1, the screw rod 31 will rotate as it moves downward, thereby driving the go / no-go gauge end 4 of the length compensation component 34 fixed to the lower end of the length compensation component 34 to rotate while moving downward. At this time, the go / no-go gauge end 4 can complete the normal threaded hole detection process. At the same time, in the process of the pressing handle 2 being pressed by an external force, since the pressing handle 2 and the upper connecting disc 30 move downward, the upper connecting disc 30 and the penetration disc The distance between 33 is shortened, forming compression on the spring 32. When the inspection is completed, the operator releases the pressing handle 2. Under the reverse force of the spring 32, the upper connecting disc 30 and the pressing handle 2 will move upward. During the movement, they will rotate in the opposite direction under the joint action of the spiral rod 31 and the penetrating disk 33, thereby driving the go / no-go gauge end 4 to complete the operation of exiting the threaded hole. It should be noted that the detachable connection between the go / no-go gauge end 4 and the length compensation component 34 should be connected by means of a snap, a keyway (or a tetrahedron / hexahedron is used as the connecting end in the attached figure), that is, the go / no-go gauge end 4 and the length compensation component 34 need to rotate at the same time and cannot slide relative to each other.

[0030] Specifically, the length compensation assembly 34 includes an outer sleeve 340, an inner sleeve 341 and a length compensation spring 342. The lower end of the inner sleeve 341 is sleeved in the outer sleeve 340, and the inner sleeve 341 is slidably connected to the outer sleeve 340. The length compensation spring 342 is located inside the outer sleeve 340, and its two ends are fixedly connected to the bottom wall of the outer sleeve 340 and the bottom wall of the inner sleeve 341 respectively.

[0031] Taking into account the different screw-in distances of the screw rod 31 and the go / no-stop gauge end 4 that may exist in actual applications, for example, the screw-in distance of the screw rod 31 after rotating 5 circles is 2 units in the vertical direction, while the screw-in distance of the go / no-stop gauge end 4 after rotating 5 circles is only 1 unit in the vertical direction. In this case, if there is no length compensation component 34, the adjustment can only be made by holding the cylindrical shell 1 to control the overall travel distance. For some novice operators, there is a situation where excessive force is used to accelerate the serious wear of the go / no-stop gauge end 4. The setting of the length compensation component 34 can indirectly change the screw-in distance of the screw rod 31 under a fixed number of rotations by compressing the length compensation spring 342, thereby achieving synchronization between the screw rod 31 and the go / no-stop gauge end 4.

[0032] Specifically, at least one group of strip grooves 3410 are provided on the curved side wall of the inner sleeve 341, and at least one group of protrusions 3400 matching the strip grooves 3410 are provided on the outer sleeve 340; considering that the spiral rod 31 needs to drive the go / no-go gauge end 4 to rotate through the length compensation component 34, the outer sleeve 340 and the inner sleeve 341 cannot rotate relative to each other. Therefore, the design of strip grooves 3410 and protrusions 3400 is adopted, which can ensure the vertical position change of the outer sleeve 340 and the inner sleeve 341, and ensure that no relative rotation occurs. It should be noted that although theoretically at least one group of strip grooves 3410 and protrusions 3400 can solve the above problems, it is best to use two or more groups to avoid the inner sleeve 341 and the outer sleeve 340 from being stuck due to the relative position deviation.

[0033] Embodiment 2

[0034] Please see attached Figure 5

[0035] The novel thread gauge is provided with an operating table 5 matched therewith, the operating table 5 comprises a fixed table 50, a rotating table 51, a thread gauge clamping assembly 52 and at least two groups of workpiece fixtures 53, the rotating table 51 is rotatably connected to the upper side of the fixed table 50, the thread gauge clamping assembly 52 is fixedly connected to the side wall of the fixed table 50, and at least two groups of workpiece fixtures 53 are evenly distributed on the upper side of the fixed table 50;

[0036] In actual applications, when a single person operates a thread gauge, the process can usually be divided into taking parts, aligning the thread gauge with the threads, testing, and placing parts. Among them, the step of aligning the thread gauge with the threads is likely to result in the most errors, especially for new employees who are new to the thread gauge, which greatly affects the overall work efficiency. In order to solve the above problems, an operating table matched with a new thread gauge is designed. After the workpiece to be tested is clamped in a fixed workpiece fixture 53, the position of the thread gauge clamping assembly 52 is adjusted and fixed. With the cooperation of at least two employees, different workpieces to be tested can be switched by rotating the table 51 at a fixed angle to perform threaded hole testing. In this process, since the positions of the thread gauge clamping assembly 52 and the workpiece fixture 53 are fixed, switching different workpieces to be tested is easy. After measuring the workpiece, the step of aligning the thread gauge with the thread is omitted, which solves the problem of incorrect alignment angle between the thread gauge and the thread that may occur in this step, and greatly improves the overall work efficiency. It should be noted that the rotating table 51 and the fixed table 50 need to be subject to certain restrictions. For example, if there are four workpiece clamps 53, the rotating table 51 can only rotate 90 degrees at a time, that is, after each rotation, different workpiece clamps 53 need to be in the same position. For example, multiple positioning holes are set on the side of the fixed table 50, and positioning pins that slide up and down are set on the rotating table. Every time a certain angle is rotated, the relative positions of the positioning pins and the positioning holes coincide, and the positioning pins fall into the positioning holes, which controls the rotation angle of the rotating table and avoids the situation where the rotating table rotates before the detection is completed (such as the attached Figure 6 ), considering that there are many methods to achieve the above purpose and the technology is mature, I will not go into details.

[0037] Specifically, the thread gauge clamping assembly 52 includes a longitudinal fixing block 520, a transverse fixing block 521, a longitudinal rod 522 and a transverse rod 523. The longitudinal fixing block 520 is fixedly connected to the side wall of the fixing platform 50. The lower end of the longitudinal rod 522 passes through the longitudinal fixing block 520 and is slidably connected thereto. The transverse fixing block 521 is fixedly connected to the upper end of the longitudinal rod 522. One end of the transverse rod 523 passes through the transverse fixing block 521 and is slidably connected thereto, and the other end is fixedly connected to the curved side wall of the cylindrical shell 1. Considering the actual application of the work to be detected The corresponding position of the thread gauge is different for different workpieces and the positions of the threaded holes on the workpieces. The combination of the longitudinal fixing block 520 and the longitudinal rod 522 can not only adjust the height, but also adjust the angle by rotating the longitudinal rod 522. That is to say, the use of the longitudinal fixing block 520 and the longitudinal rod 522 makes the coverage area of ​​the thread gauge clamping assembly 52 a circular area with the longitudinal rod 522 as the center, and the combination of the transverse fixing block 521 and the transverse rod 523 can control the radius of the above-mentioned circular area. The above method can expand the working area that the thread gauge clamping assembly 52 can cover.

[0038] Specifically, the longitudinal fixing block 520 and the transverse fixing block 521 are provided with locking handles 5200 for the positions of the longitudinal rod 522 and the transverse rod 523; considering that the longitudinal fixing block 520 and the transverse fixing block 521 are in different positions but have similar functions, locking handles 5200 with the same functions are respectively provided on the longitudinal fixing block 520 and the transverse fixing block 521 to lock the adjusted position.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
