Novel external thread detects device

Technical Field

The utility model belongs to the technical field of mechanical detection equipment, a novel external screw thread detects is related to.

Background

The thread detection is an important work required to be carried out after thread machining and is also an important basis for evaluating the accuracy and the quality of threads, the principle of the thread detection is that a part with an internal thread structure rotates in the forward and reverse directions, an external thread workpiece to be detected is placed on the part and screwed and loosened through thread matching, and whether the external thread of the workpiece is qualified or not is judged through the action of easiness and no obstacle.

The conventional thread detection device is generally driven by a motor to rotate, the structure is complex, the manufacturing cost is high, and a plurality of inconveniences exist in the control and adjustment of the torque force.

Disclosure of Invention

The utility model aims at providing a simple structure and make the novel external screw thread detection device who adjusts more convenient through pneumatic mode to the above-mentioned problem that exists among the prior art.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a novel external screw thread detects device, includes pneumatic motor, switching-over valve and screw thread ring gage, its characterized in that, pneumatic motor on be fixed with the mount pad, the mount pad in clearance fit have the carousel, the bottom center of carousel links firmly with pneumatic motor's pivot mutually, screw thread ring gage tight cooperation of rising be fixed in the carousel in, the switching-over valve on have an air inlet and two gas outlets, two gas outlets pass through the trachea and be connected the realization power input with pneumatic motor.

The principle of the novel external thread detection device is as follows: the pneumatic motor is driven to operate by high-pressure gas input by the air pump, the pneumatic motor is provided with two air pipes connected with the reversing valve, the conduction path of the pneumatic motor is controlled by the reversing valve, namely, one air pipe realizes the forward rotation of the pneumatic motor, and the other air pipe realizes the reverse rotation of the pneumatic motor, so that the threaded ring gauge can rotate forward and backward, the threaded part of an external thread workpiece to be detected is aligned with the threaded ring gauge, when the pneumatic motor rotates forward, the workpiece is screwed through thread fit, otherwise, when the pneumatic motor rotates backward, the workpiece is rotated out, the design enables the workpiece to be matched with the threaded ring gauge in the process, the rated torque and the rated rotating speed of the pneumatic motor are set, when the thread is unqualified, the rotation of the threaded ring gauge is clamped, and whether the thread of the workpiece is qualified is judged.

In the novel external thread detection device, a flow pressure regulating valve is arranged at the joint of the pneumatic motor and the air pipe.

In the novel external thread detection device, the edges of the upper end surface and the lower end surface of the thread ring gauge are in a chamfer structure.

In the novel external thread detection device, the side surface of the thread ring gauge is provided with an anti-skid friction structure.

In the novel external thread detection device, the reversing valve is controlled and adjusted through the handle.

Compared with the prior art, this novel external screw thread detection device has following advantage:

1. the rotation of the thread ring gauge is controlled by the pneumatic motor, and the direction of the thread ring gauge is indirectly controlled by the reversing valve, so that the integral structure is simple, and the manufacturing cost is low;

2. the pneumatic structure is more convenient to control and adjust;

3. the thread ring gauge is detachably installed, different types of thread ring gauges can be selected according to the thread diameter of a workpiece, and the thread ring gauge is more convenient to replace due to the tight fixed fit friction structure.
