Description

Technical Field

[0001] This utility model relates to the technical field of electric thread testing machines, and in particular to an electric thread testing machine. Background Technology

[0002] As a common structural form in mechanical parts, threads are easy to assemble, disassemble, and transmit power, and are therefore widely used in fields such as machinery manufacturing, aerospace, nuclear power, chemical industry, and military industry. However, the quality of the geometric parameters of threaded parts directly affects their performance, so thread inspection technology is crucial in the production process.

[0003] Traditional thread inspection methods mainly rely on manual measurement or partially automated equipment. These methods can often only detect some parameters of the thread and lack an overall pass / fail standard, making it difficult to meet the high precision and efficiency requirements of modern production. The emergence of electric thread inspection machines has solved this problem well. However, existing electric thread inspection machines generally require adjusting the position of the sensor and the distance between the thread gauge and the thread hole being tested by screws. Position adjustment is inconvenient, and the fixture is generally fixed on the base plate, making it inconvenient to adjust the position of the fixture center point, resulting in low inspection accuracy.

[0004] Therefore, to address the problems of inconvenient position adjustment and low positioning accuracy of the tool center point, a thread electric inspection machine can be designed. Utility Model Content

[0005] To overcome the problems of inconvenient position adjustment and low positioning accuracy of the tool center point.

[0006] The technical solution of this utility model is as follows: a thread electric inspection machine, including a base, a main control box fixedly connected to the upper end of the base, a rotating shaft rotatably connected inside the main control box, and a three-jaw chuck fixedly connected to the end of the rotating shaft; it also includes a guide rod, a locking sleeve and a slide rail, the guide rods are symmetrically distributed about the front and rear of the rotating shaft inserted into the main control box, the locking sleeve is sleeved on the outer side of the left end of the guide rod, a detachable clamp is installed on the right end of the two guide rods, a fixture is installed on the inner side of the clamp, the slide rail is fixedly connected to the rear end of the main control box, two sets of sensors are slidably connected to the upper end of the slide rail, and a positioning frame is installed on the right end of the clamp near the sensor.

[0007] Preferably, the main control box is placed in a stable position using the base. Depending on the requirements, the appropriate fixture and jig are selected. The fixture is installed on the right end of the guide rod and adjusted forward and backward to a suitable position. Then, the jig and fixture are installed. The fixture is adjusted left and right, and the jig is adjusted up and down to ensure alignment with the center point of the three-jaw chuck. The thread gauge is placed in the three-jaw chuck and fully clamped. The part to be measured is placed into the jig. The distance between the thread gauge and the thread measuring hole is adjusted using the locking sleeve. The positions of the two sets of sensors are adjusted using the slide rail to ensure that the positioning frame can be detected by the sensors. Then, thread testing is performed.

[0008] Preferably, the upper end of the slide rail is slidably connected to two sets of horizontally adjustable sliders, the upper end of the sliders is fixedly connected to a mounting bracket, and a sensor is installed on the upper end of the mounting bracket.

[0009] As a preferred option, a return spring is fixedly connected inside the main control box and sleeved on the outside of the optical rod. The fixture is designed with different specifications according to the needs of use.

[0010] Preferably, a display screen is fixedly connected to the front end of the main control box, and symmetrically distributed handles are fixedly connected to the upper end of the base.

[0011] Preferably, the right end of the guide rod is fixedly connected to the clamp by an adjusting bolt, and the clamp is provided with a second adjusting groove, into which the adjusting bolt is inserted.

[0012] Preferably, the fixture has a first adjustment groove in the middle, and the fixture is connected to the fixture through fasteners and the first adjustment groove.

[0013] Preferably, the positioning frame is provided with a third adjustment groove, and the positioning frame is connected to the clamp by fasteners.

[0014] The beneficial effects of this utility model are as follows: By matching different fixtures to threaded parts, the versatility of the thread electric inspection machine is ensured. The position of the light rod can be quickly adjusted and positioned by the locking sleeve. The positions of the fixture and the jig can also be adjusted, thereby ensuring the accuracy of the detection position. Different types of threaded parts can be detected by simply changing the fixture, which can reduce the time for adjusting and changing different parts and save the time of tightening screws and nuts. The position of the sensor can be adjusted by sliding without fasteners, making the adjustment simpler. Attached Figure Description
