Description

Automatic change moment of torsion measuring device

Technical Field

The invention relates to the field of automatic door closer preparation, in particular to an automatic torque measuring device.

Background

Door closers are used primarily in commercial and public buildings, but are also used in the home. They have many uses, the most important of which is to close the door itself, limiting the spread of fire and ventilation inside the building.

The basic components of the automatic door closer comprise a supporting guide piece, a transmission gear, a return spring, a one-way valve, a rack plunger, a throttle valve core, a shell, an end cover, a sealing ring and a connecting rod. The shell and the connecting rod play roles in fixing the door closer and connecting the door leaf and the door frame.

The working principle of the automatic door closer is as follows: when the door is opened, the door body drives the connecting rod to act, and the transmission gear is rotated to drive the rack plunger to move rightwards. The spring is compressed during the right movement of the plunger, and the hydraulic oil in the right chamber is also pressurized. The check valve ball body on the left side of the plunger is opened under the action of oil pressure, and hydraulic oil in the right cavity flows into the left cavity through the check valve. After the door opening process is finished, the spring is compressed in the opening process, so that the accumulated elastic potential energy is released, the plunger is pushed to the left side, the transmission gear and the door closer connecting rod are driven to rotate, and the door is closed.

Although the automatic door closer is a common component, in the detection stage after the production and preparation of the automatic door closer, the automatic door closer is usually rotated manually to sense the torsion and the rotation angle, so that the automatic door closer has the problems of large error, time and labor waste and the like, and the automatic door closer is speaking completely through experience and cannot meet the requirement of high quality.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it.

Referring to fig. 1 and 2, an embodiment of an automatic torque measuring device of the present invention includes an indexing rotary disk 1, on which a plurality of jigs 2 are arranged, a feeding station and a detecting station are arranged around the indexing rotary disk, a first platform 5 moving along X and Y axes and a second platform 6 moving along X, Y and Z axes are arranged in the detecting station, a gear motor 7, a clutch 8, a torque measurer 9 and a sleeve 10 are sequentially connected on the first platform, and an electric screw driver 11 is arranged on the second platform;

The door closer 12 is placed on the jig through the manual work at the feeding station and fixed through the jig, the jig fixed with the door closer is rotated to the detection station through the rotation of the indexing rotary disk, oil pressure screws on the door closer are in locking states, a first platform in the detection station moves along the Y-axis direction, a sleeve is sleeved on a rotating shaft part of the door closer, a gear motor acts, rotating power is transmitted through a clutch and a torque measurer, the sleeve rotates a rotating shaft part, door opening actions are simulated, at the moment, the change of recording torque can be detected through the torque measurer, whether abnormal conditions such as clamping stagnation exist or not, after the rotating is completed, the clutch is broken, the rotating shaft part can rebound by a certain angle due to the fact that the clutch is not limited, at the moment, the rebound angle can be detected through the torque measurer, the ordinary rebound angle is between 15-22 degrees, then the second platform is used for carrying out electric screw driver action, oil can be loosened, at the moment, the rebound angle can be continuously detected through the torque measurer, all detection in the action process is met, the purposes of high precision and good automatic effect are achieved.
