Description

Technical Field

[0001] This utility model relates to the field of thread inspection technology, specifically to a thread inspection machine. Background Technology

[0002] A thread inspection machine is a device specifically designed to inspect the quality and precision of threads. It is widely used in fields such as machinery manufacturing, automotive industry, and aerospace. Its main function is to ensure that the dimensions, shape, precision, and surface quality of the threads meet the design requirements, thereby guaranteeing the performance and safety of the threads in practical applications.

[0003] CN216745777U discloses a thread inspection machine, including a support base. A first motor and a second motor are mounted on the upper side of the support base. A first main pulley is located in front of the first motor, with one end of a first belt fitted onto the outer side of the first main pulley. A first driven pulley is fitted onto the other end of the first belt. A second main pulley is located behind the second motor. This invention uses a friction plate to rub against the rotating first driven pulley, causing the thread ring gauge to rotate with the friction plate. The rotation depth is visually determined to reach the root of the workpiece thread. Then, by holding the workpiece and gently pulling it back, the friction plate also retracts, rubbing against the rotating second driven pulley. Simultaneously, the thread ring gauge rotates in the opposite direction with the second driven pulley, causing the workpiece to be reversed and ejected. This completes the inspection of one workpiece. For batch inspections, this significantly improves the work efficiency of operators and saves a considerable amount of time.

[0004] The aforementioned patent addresses the shortcomings of the conventional inspection method in the prior art, which involves operators manually monitoring threaded workpieces, resulting in high workload and poor inspection accuracy. However, the patent's technical solution makes it inconvenient to replace the thread ring gauge and does not include a thread plug gauge, making it impossible to inspect workpieces with different thread specifications and different threads, thus resulting in poor adaptability of the thread inspection machine.

A triangular limiting post is fixedly installed inside the magnetic sleeve. A magnetic post is fixedly installed at one end of the threaded plug gauge. A triangular limiting groove extending to one side surface of the magnetic post is opened inside the magnetic post.

[0008] Furthermore, the outer diameter of the threaded ring gauge is adapted to the inner diameter of the fixed sleeve, and the locking block is adapted to the locking groove.

[0009] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the insertion of the thread ring gauge into the fixed sleeve and limits the movement of the thread ring gauge.

[0010] Furthermore, three first positioning pins are fixedly installed on one side surface of the first magnetic ring, and three first positioning holes are opened on the surfaces of the threaded ring gauge and the second magnetic ring, with the first positioning pins matching the first positioning holes.

[0011] The advantage of adopting the above-mentioned further solution is that it makes it easier to insert the card block into the card slot.

[0012] Furthermore, the magnetic column has three second positioning holes extending to one side surface of the magnetic column, and the magnetic sleeve has three second positioning pins fixedly installed inside, the second positioning pins being adapted to the second positioning holes.

[0013] The advantage of adopting the above-mentioned further solution is that it makes it easier to insert the magnetic column into the magnetic sleeve.

[0014] Furthermore, the triangular limiting post is adapted to the triangular limiting groove.

[0015] The beneficial effect of adopting the above-mentioned further solution is that it makes it easier to insert the triangular limiting post into the triangular limiting groove.

[0016] Furthermore, four guide rods are fixedly installed on the inner side of the C-shaped frame, and every two guide rods form a through connecting plate.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the guide rod can limit the movement of the motor and increase the stability of the motor during operation.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] This thread inspection machine features a hollow rotating shaft and a magnetic snap-fit ​​connection mechanism between the shaft and thread ring gauges and thread plug gauges. This allows for quick replacement of thread ring gauges and thread plug gauges during use, enabling the machine to adapt to different threaded workpieces. This significantly improves the machine's adaptability and solves the problems of existing thread inspection machines, which are inconvenient to replace thread ring gauges and lack thread plug gauges, making it impossible to inspect workpieces with different thread specifications and threads, resulting in poor adaptability.
