More specifically, the outer wall of the ejector rod 8 close to one end of the detection block 2 is provided with a second annular boss 8.1, and an elastic reset piece 9 is arranged between the second annular boss 8.1 and the sliding shaft sleeve 7, so that the ejector rod 8 always has a tendency of moving towards the direction far away from the displacement sensor 6 and keeping abutting against the detection block 2. That is, after the detection is completed, when the detection tool is withdrawn from the detection area, the detection block 2 losing the axial thrust can be rapidly reset and moved to the initial position in the direction away from the handle 1 by the elastic reset piece 9. Preferably, elasticity piece 9 that resets is cylindrical spring, and cylindrical spring suit is in the outside of ejector pin 8, and cylindrical spring's both ends respectively with second annular boss 8.1, 7 tip looks butt of slip axle sleeve, and the spring suit sets up stability good in the outside of ejector pin 8, and elasticity restoring force is steady.

As shown in fig. 1 and 3, in this embodiment, a manual button 10 is connected to an outer wall of the handle 1 for convenience of operation, and the opening or closing of the manual button 10 is used to connect or disconnect the controller to or from the displacement detecting assembly. Specifically, the outer wall of the handle 1 is connected with two split type hoop blocks 16, the manual button 10 is movably installed on any one hoop block 16 along the radial direction, the displacement sensor 6 and the controller are respectively connected to a first contact inside the manual button 10 through a cable (not shown in the figure), a movable block outside the manual button 10 is connected with a second contact, and the two contacts are contacted or disconnected through the movement of the movable block, so that the connection or disconnection between the controller and the displacement detection assembly is realized, and the transmission of detection signals is more stable and controllable through the connection mode of the cables.

As shown in figures 2 and 4, one end of the limiting block 3, which is far away from the handle 1, is provided with a positioning groove 3.1 which is matched with the appearance of the target workpiece 5, which is close to the position of the C-shaped locking plate 4, so that the accurate limiting of the movement displacement of the detecting block 2 is ensured. In addition, the positions of the two sides of the positioning groove 3.1 on the limiting block 3 are provided with positioning lugs 3.2, and the distance between the two positioning lugs 3.2 is matched with the width of the C-shaped locking plate 4.

On the other hand, the handle 1 is also connected with a guide block 11 which is in the same direction as the detection block 2, the detection block 2 is positioned between the guide block 11 and the limiting block 3, and one end of the guide block 11 is provided with a guide groove 11.1 matched with the first annular boss 5.1 on the outer wall of the target workpiece 5; during detection, when the guide block 11 is clamped into the first annular boss 5.1 along the set position, the detection block 2 is accurately aligned with the C-shaped locking plate 4. Specifically, as shown in fig. 4, the C-shaped locking plate 4 and the target workpiece 5 are parts on the supercharger; the target workpiece 5 is mainly used for connecting and fixing a first part 17 and a second part 18, and after the connection is finished, the end part of the target workpiece is axially limited by a C-shaped locking plate 4; the guide block 11 in the structure has the purpose of guiding and facilitating the insertion of a C-shaped locking plate detection tool into a detected object; the in-process that C type locking plate detected the instrument and inserted the testee promptly keeps the horizontal terminal surface of guide block 11 to paste mutually with the terminal surface of first part 17 to guide way 11.1 is corresponding with first annular boss 5.1 on the 5 outer walls of target work piece, thereby can guarantee to detect the instrument and stretch into detection area back along this position, detects the position of piece 2 can be accurate with wait to detect C type locking plate 4 counterpoint. In the detection, whether the C-shaped locking piece 4 is deformed (enlarged) is firstly detected through the width between the two positioning lugs 3.2. If the C-shaped locking plate 4 is not deformed, the C-shaped locking plate can smoothly pass through the gap between the two positioning lugs 3.2; if C type locking plate 4 takes place to warp (grow), then can not be through the clearance between two location lugs 3.2, C type locking plate 4 also can not contact this moment and detect piece 2, and displacement sensor 6's value can not change, can not be in the qualified scope of displacement value of settlement to can discern the locking plate and warp (grow). In the process, when the operator pushes the detection tool to move to the dead state (the C-shaped locking piece 4 and the two positioning bumps 3.2 are locked), the manual button 10 is pressed, the displacement sensor 6 transmits the detected displacement value to the controller, and the detection result is judged by comparing the displacement value.

As shown in fig. 6 and 7, when the C-shaped locking piece 4 is not deformed, further detection is performed; during detection, after the C-shaped locking plate 4 passes through the gap between the two positioning lugs 3.2, the C-shaped locking plate 4 is abutted against the detection end of the detection block 2, the handle 1 is continuously pushed to move forwards at the moment, the detection block 2 moves towards one end of the handle 1 under the action of the reverse thrust of the C-shaped locking plate 4, and the detection head of the displacement sensor 6 is synchronously pushed in the moving process; until the groove bottom of the positioning groove 3.1 on the limiting block 3 is abutted against the outer wall of the target workpiece 5, namely, when the detection block 2 cannot move continuously, an operator presses the manual button 10, the displacement sensor 6 transmits the detected displacement value to the controller, and the detection result is judged by comparing the displacement value. More specifically, in the detection process of this step; when the detection tool stretches into the detection area for detection, the outer end of the detection block 2 is abutted against the C-shaped locking plate 4 in advance, the detection block 2 slides towards one end of the handle 1 under the action force of the C-shaped locking plate 4, and a position value can be obtained through the displacement sensor 6; if C type locking plate neglected loading in this structure, then detect the time earlier with detect the piece 4 outer terminal surface butt then the lateral wall of target work piece 5, detect the piece 4 also can move towards handle 1 direction under this lateral wall reverse butt pressure effect, just displacement sensor 6 obtains again another displacement value this moment, through the different displacement values that displacement sensor 6 detected with the controller in the reference displacement value of predetermineeing contrast, judge that C type locking plate 4 is the installation not in place or neglected loading.

Furthermore, the C-shaped locking plate detection tool in this embodiment can be set to be standardized, serialized: corresponding to the C-shaped locking plate 4 of different specifications promptly, only need to modify the size that the profile of locating piece 3, detection piece 2, guide block 11 and C-shaped locking plate 4 is relevant and can realize that this locking plate detects standardization, serialization of instrument.

Compare in the 4 installation conditions of current industry camera detection C type locking plate, this novel C type locking plate detects instrument is more economical, flexible, and can be simultaneously reliable and stable discernment locking plate neglected loading, assemble not in place, three kinds of inefficacys of locking plate permanent deformation (grow). In addition, the use of the tool is less influenced by the installation space of the C-shaped locking piece 4; the detection of the C-shaped locking plate 4 with different specifications can be adapted only by modifying part of the size of the tool.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and such changes and modifications will fall within the scope of the present invention.
