Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to an elastic force detection clamp. Background Art
[0002] Traditional spring force testing machines directly place the spring on the test station and pressurize it when testing the spring force. During the test, the spring often deforms and bounces off. This is especially serious when testing the elastic force of slender springs with a length-to-outer-diameter ratio of more than 20 and a working elastic force of more than 2000N. In order to solve this technical problem, the current solution is to fix the spring from both sides with a limit fixture before testing. Although the limit fixture can prevent the spring from bouncing off, it will cause partial deformation of the spring, resulting in inaccurate test data. In addition, the limit fixture has a complex structure and cumbersome installation steps. It takes a long time to install the limit fixture, which takes up a lot of test time and reduces test efficiency. To this end, we propose a spring force detection fixture. Utility Model Content

The motor is installed at the frame wall of the load-bearing frame by bolts, a threaded rod is installed at the output end of the motor, and a concave frame is threadedly connected at the rod wall of the threaded rod, a cross bar is welded at the frame wall of the load-bearing frame, and the cross bar passes through the concave frame, a concave disk is installed at the frame wall of the load-bearing frame, a sleeve is connected at the frame wall of the concave frame through the pressure sensor, a group of symmetrical card slots are opened at the frame wall of the concave frame, a group of symmetrical card plates are welded at the bottom of the cover plate, and the card plates are located in the card slots, and a glass plate is installed at the plate wall of the cover plate.
[0005] By adopting the above technical scheme, when the elastic force of the spring is tested, since a detection mechanism is installed on the wall of the support frame, the detection mechanism is composed of a motor, a threaded rod, a cross bar, a concave frame, a concave disk, a pressure sensor, a sleeve, a cover plate, a glass plate, a card plate and a card slot combination. After the personnel places the spring between the concave disk and the sleeve, the motor is controlled by the controller so that the motor drives the threaded rod to rotate.

Since a group of symmetrical card slots are opened on the frame wall of the concave frame, after taking the cover plate, the card plate is inserted into the card slot to fix the cover plate. Since the sleeve and the concave frame are connected by a pressure sensor, when the spring is squeezed, the pressure sensor transmits the detected pressure to the controller, and the spring pressure is displayed by the controller to avoid the spring splashing and injuring personnel after being squeezed.
[0006] Specifically, it also includes a limiting mechanism, and the limiting mechanism is installed on the cylinder wall of the sleeve.
[0007] By adopting the above technical solution, the spring can be limited by the limiting mechanism.
[0008] Specifically, the limiting mechanism is composed of a screw rod, an arc clamp and a rubber pad. A group of symmetrical screw rods are threadedly connected to the wall of the sleeve. The other end of the group of screw rods is connected to the wall of the arc clamp through a bearing. A rubber pad is adhered to the arc of the arc clamp.

After placing the spring between the sleeves, the personnel twists the screw rod to make the screw rod push the arc clamp plate, and the arc clamp plate limits the spring, thereby realizing limited extrusion detection of the spring.
[0010] Specifically, a controller for controlling the motor is installed on the wall of the support frame.
[0011] By adopting the above technical solution, the motor can be conveniently controlled through the controller.
[0012] Specifically, a bracket is welded at the bottom of the support frame.
