DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

The bottom end of the node hole 305 is connected to the installation slide groove, and the top end of the clamp block 304 is slidably matched with the installation slide groove. A threaded hole is opened at the top end of the clamp block 304, and the clamping jaw 303 is threadedly connected to the top end of the clamp block 304 through a bolt penetrating the adjustment hole 305. The cylinder 301 is the power source of the pneumatic clamp assembly 3, and the piston rod is driven by compressed air to move in a telescopic manner. The transmission mechanism 302 is used to convert the linear motion of the piston rod into the clamping action of the clamping jaw 303. The clamping jaws 303 on the upper and lower sides realize the opening and closing action through the action of the transmission mechanism 302. The surface of the clamp block 304 usually has a certain texture to increase the friction of clamping;

[0021] When it is necessary to replace the clamp block 304, first, use a tool to loosen the bolt threaded in the threaded hole at the top of the clamp block 304. After the bolt is completely removed, the clamp block 304 is no longer fixed and can slide outward along the installation slide groove to remove the old clamp block 304 from the clamp jaw 303. Select a suitable clamp block 304 as needed, align its top end with the installation slide groove, and slide it into the installation slide groove of the clamp jaw 303 so that it can better clamp the spring. Then insert the bolt into the adjustment hole 305 and screw it into the threaded hole at the top of the clamp block 304. Gradually tighten the bolt to firmly fix the clamp block 304 on the clamp jaw 303, thereby meeting the clamping requirements of different springs and improving the versatility and applicability of the spring torque test machine.

A rotating handle 7 is installed at one end of the screw rod 5, and a rotating clamp 8 is installed on the top of the slider 6. The pneumatic clamp assembly 3 is vertically arranged on one side of the connecting seat 2, and the pneumatic clamp assembly 3 and the rotating clamp 8 are arranged opposite to each other. A gap is provided between the pneumatic clamp assembly 3 and the rotating clamp 8 to accommodate the spring to be tested. Mounting seats are respectively arranged at both ends of the screw rod 5, and the bottom end of the slider 6 is slidably connected to the guide rail 4. The screw rod 5 is connected to the guide rail 4 through the slider 6. The slider 6 on the screw rod 5 can perform precise linear movement along the thread of the screw rod 5. The operator can manually rotate the rotating handle 7 to drive the screw rod 5 to rotate, thereby realizing the position adjustment of the slider 6 on the guide rail 4, thereby realizing the precise adjustment of the position of the rotating clamp 8, which can meet the requirements of various precision tests and operations. This kind of testing machine is externally provided with a corresponding control system and a data acquisition and processing system.
