The objective of the invention is to be achieved through the following technical solutions:
The present invention includes servomotor, torque sensor, measuring head assembly and clamp system, recliner is positioned the worktable on the switch board, clamp system is arranged at the recliner top, can clamp recliner, the below of worktable is provided with the measuring head assembly, the one end is passed by worktable and recliner, and the other end is provided with torque sensor, recliner and measuring head assembly interlock; Servomotor is connected with torque sensor.
Wherein: also be provided with positioning component between recliner and the worktable, recliner is by positioning component and clamp system is fastening is positioned on the worktable; Described positioning component comprises locating piece and register pin, and locating piece is provided with register pin, and recliner is plugged on the register pin, is used for the location; On the worktable of measuring head assembly one side, be provided with detection and whether lay the workpiece sensing sensor of recliner; On the worktable of clamp system one side, be provided with and detect the clamping detecting sensor whether recliner clamps; Described measuring head assembly comprises transition axis, universal joint and measuring head, and an end of measuring head passes worktable and links to each other with recliner, and the other end is connected in universal joint, and an end of transition axis is connected with universal joint, and the other end is connected with torque sensor; Described clamp system comprises quick-speed jigs, clamping head, movable joint and plate, and clamping head is arranged at the end away from the quick-speed jigs handle, and clamping head is plugged on the recliner, clamps recliner.
Advantage of the present invention and good effect are:
1. the present invention adopts servomotor to drive the measuring head rotation, applies moment of torsion to recliner automatically, has avoided the error of manual operation, and the measuring accuracy height has also improved production efficiency simultaneously.
2. the present invention passes through the torque sensor output signal, and shows by display, can make the testing staff observe testing result intuitively, has exempted manual record, has further improved measuring accuracy and production efficiency.
3. recliner can accurately be located by positioning component on worktable, clamps by clamp system, and is simple to operate.
4. workpiece sensing sensor of She Zhiing and anchor clamps detecting sensor can so that whether the alert recliner install, and whether clamp system clamps recliner.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the present invention includes servomotor 2, torque sensor 4, measuring head assembly 5 and clamp system 7, one worktable 9 is arranged on the frame 1 of switch board 13, be provided with positioning component 8 between recliner 11 and the worktable 9, be used for recliner is positioned at worktable.Clamp system 7 is arranged at the top of recliner 11, is used to clamp recliner.Recliner 11 can be fastening by positioning component 8 and clamp system 7 and be accurately positioned on the worktable 9.The below of worktable 9 is provided with measuring head assembly 5, and the one end is passed by worktable 9 and recliner 11, and the other end is connected with the output shaft of torque sensor 4, and recliner 11 is along with measuring head assembly 5 interlocks.The output shaft of servomotor 2 is connected with the input shaft of torque sensor 4 by shaft coupling 3.On the worktable 9 of measuring head assembly 5 one sides, be provided with detection and whether laid the workpiece sensing sensor 10 of recliner.On the worktable 9 of clamp system 7 one sides, be provided with and detect the clamping detecting sensor 12 whether recliner clamps.
As shown in Figure 3, measuring head assembly 5 comprises transition axis 51, universal joint 52 and measuring head 53.One end of measuring head 53 passes the splined hole that worktable 9 is plugged on the recliner middle part, and the other end connects universal joint 52, and an end of transition axis 51 is connected with universal joint 52, and the other end is connected with torque sensor 4.As Fig. 4, shown in Figure 5, positioning component 8 comprises locating piece 81 and register pin 82, and locating piece 81 is provided with register pin 82, and it is plugged in the pilot hole on the recliner 11, is used for the location of recliner.As Fig. 6, shown in Figure 7, clamp system 7 comprises quick-speed jigs 71, clamping head 72, movable joint 73 and plate 74, and clamping head 72 is arranged at the end away from quick-speed jigs 71 handles, and clamping head 72 is plugged in the fabrication hole of recliner, clamps recliner.
Principle of work of the present invention is: the output shaft of servomotor 2 is connected with the input shaft of torque sensor 4 by shaft coupling 3, and the output shaft of torque sensor 4 drives measuring head 53 by universal joint 52 and rotates.At first, recliner 11 is installed manually, it is accurately positioned on the register pin 82 of locating piece 81, move quick-speed jigs 71 then downwards, clamping head 72 in the fabrication hole that inserts recliner, clamps recliner downwards.Servomotor 2 work, drive torque sensor 4 and measuring head 53 rotations by shaft coupling 3, apply a moment of torsion for recliner 11, torque sensor 4 reaches the input end of controller (present embodiment adopt single-chip microcomputer or PLC) with detected signal, exports display to after this detection signal via controller is handled and shows.After measuring end, manually unload recliner.
After manual installation recliner, workpiece sensing sensor 10 can be exported the signal whether recliner installs, and anchor clamps detecting sensor 12 can be exported the signal whether recliner clamps, so that the prompting staff.What the present embodiment sensor adopted is photoelectric sensor.
