Description

Technical Field

[0001] The utility model belongs to the field of hinge detection devices, and particularly relates to a hinge inspection fixture. Background Art

[0002] A hinge, also known as a hinge joint, is a mechanical device that can connect two or more components together and allow a certain amount of rotation or swing between them. In order to test the quality of hinge products, it is usually necessary to randomly sample the products on the hinge production line before leaving the factory, and then use a detection fixture device to install the hinge and perform tens of thousands of opening and closing operations to test the service quality of the hinge.

[0003] In the prior art, the core problem faced by the current hinge inspection fixture lies in the limitations of the test design, which are mainly reflected in two aspects: First, the test method usually only evaluates the hinge performance through repeated opening and closing actions, ignoring the complex usage scenarios that may be encountered in daily life, such as rapid or forceful door pulling and closing operations, which pose higher requirements for the durability and stability of the hinge. Second, the weight of the installation object is often not considered during the inspection process, especially the impact of this weight on the opening and closing performance when the hinge is vertically stressed, which may lead to a deviation between the inspection result and the actual usage situation. Therefore, in order to more accurately evaluate the performance of the hinge, it is necessary to improve the inspection fixture to cover a wider and more realistic test scenario.

[0004] Therefore, a hinge inspection fixture is proposed, which has an opening and closing structure with adjustable force and a placement structure with adjustable load, and can imitate the real situation of daily life by adjusting different forces and solve the problem of the influence of the weight of different installation objects on the vertical force of the hinge, so as to improve the accuracy of the inspection device. Summary of the Utility Model

[0005] In order to overcome the problems of single test scenario and neglect of the influence of the weight of different installation objects on the vertical force of the hinge in the existing hinge inspection fixture, resulting in incomplete inspection results.

[0006] The technical solution of the present utility model is: an inspection hinge fixture, including a base; a first support column, a second support column and a third support column are fixedly connected to the upper end of the base, and a movable door assembly for inspection is arranged on the first support column, and an elastic assembly for simulating opening and closing is arranged on the second support column. The movable door assembly includes a second fixed block, a hinge and a movable door; a second fixed block is fixedly connected to the right end of the first support column, a detector is fixedly connected to the front end of the first support column, a hinge is fixedly connected to the right end of the second fixed block, a movable door is arranged to the right of the second fixed block, the second fixed block and the movable door are hinged by the hinge, a first fixed block is fixedly connected to the upper end of the first support column, a motor is fixedly connected to the arc-shaped outer wall of the first fixed block, the lower end of the output shaft of the motor is fixedly connected to a rocker arm, and clamping blocks are fixedly connected to the front and rear ends of the rocker arm. One end of the two clamping blocks close to each other fits with the front and rear ends of the movable door.

[0007] Preferably, by installing the hinge on the second fixed block and the movable door, then connecting a corresponding number of belts on two third fixed blocks, and then starting the motor, the output shaft of the motor drives the rocker arm to rotate, and the two clamping blocks on the rocker arm clamp the movable door, so that the movable door rotates and opens and closes along the hinge axis. When the front end of the movable door fits with the left end of the detector, the motor is turned off, and the movable door is quickly closed under the tension of the elastic assembly. By setting the number of belts, different degrees of closing work are simulated. By adding weight rings at different positions on the movable door assembly, the influence of the vertical force of installation parts of different weights on the hinge on the performance of the hinge is simulated, solving the problem that the inspection link is relatively single when using a hinge fixture inspection device.

[0008] As a preference, the movable door assembly includes a first stud, a weight ring and a nut; two first studs are fixedly connected to the front and rear ends of the movable door, nuts are movably arranged on the first studs, weight rings are threadedly installed on the outer walls of the first studs, and the rear ends of the weight rings fit with the front ends of the nuts. By adding corresponding weight rings on the first studs and then rotating the nuts on the first studs, the weight rings installed on the first studs are fixed to prevent accidents during the opening and closing of the movable door. At the same time, by installing weight rings on different first studs on the movable door, the weights and center of gravity positions of different door panels can be simulated.

[0009] Preferably, the elastic component includes a third fixing block, a second groove, a third groove, a fourth groove and a screw groove; the upper end of the second support column is fixedly connected with the third fixing block, three second grooves are opened at the upper end of the third fixing block, and the lower end inner wall of the second groove is provided with the third groove and the fourth groove, the third groove and the fourth groove communicate with each other, and two screw grooves are opened at the upper end of the third fixing block. Through the three second grooves provided on the third fixing block, when an elastic belt is inserted, different closing movements with different forces can be simulated according to the number of inserted belts, so that by the method of controlling variables, the tolerance of the hinge can be effectively tested, and the accuracy during the test is improved.

[0010] Preferably, the elastic components are respectively arranged above the second support column and behind the movable door. By connecting the two third fixing blocks with a belt, a backward pulling force can be generated during the forward flipping process of the movable door, which is used to simulate the work of quickly closing the board.

By inserting the limiting post into the corresponding third groove, the two third fixing blocks can be connected by the belt on the limiting post.

When the corresponding number of limiting posts are inserted into the third groove, place the fourth fixing block above the third fixing block, insert the insertion block at the lower end of the fourth fixing block into the second groove, then insert the insertion post below the insertion block into the slot, and then use the second screw post to pass through the fourth fixing block and threadedly install it in the screw groove to fix the fourth fixing block above the third fixing block, thereby fixing the limiting post in the third groove.

[0013] Preferably, a limiting rod is fixedly connected to the outer wall of the first support column close to the belt. A first groove is formed at the front end of the third support column. A rubber pad is fixedly connected to the inner wall of the first groove. The front end of the rubber pad is attached to the rear end of the movable door. Through the limiting rod, when the movable door rotates forward, it can prevent the outer wall of the belt from contacting the outer wall of the first support column, thus preventing the belt from being worn by the outer wall of the first support column and breaking during long-term stretching. Through the rubber pad on the first groove, the force can be relieved during the backward rotation of the movable door, preventing the problem of bending damage to the movable door.

[0014] Advantages of the present utility model:

[0015] 1.

Through the rubber pad on the first groove, the force can be relieved during the backward rotation of the movable door, preventing the problem of bending damage to the movable door.
