In order to facilitate the installation or the disassembly and assembly of the motor and the paddle, and save the camera device and the mechanical arm which are specially used for positioning the paddle and the motor, the self-resetting of the support plate 1 relative to the adapter plate 2 can be realized, so that the automatic positioning cost is effectively reduced, the support plate 1 can reciprocate up and down relative to the adapter plate 2 through a preset part, and the preset part can be a lifting cylinder (not shown) so as to realize the automatic design of the positioning clamp. The carrier plate 1 is provided with a second mounting part 11 for fixing a lifting cylinder, the adapter plate 2 is provided with a cylinder lifting groove 21 corresponding to the second mounting part 11, and the lifting cylinder penetrates through the cylinder lifting groove 21 and is connected with the second mounting part 11; in the embodiment of the present application, the second mounting portion 11 is a second screw hole structure, and the lifting cylinder is fixed on the carrier plate 1 through the matched screw passing through the second screw hole structure, of course, in other embodiments of the present application, the second mounting portion 11 may also be a detachable locking structure such as a buckle or a clamping groove, and the embodiment of the present application does not limit this to this

Wherein, because profile modeling groove 10 and constant head tank 20 are after fixing a position paddle and motor respectively, paddle and motor still are located profile modeling groove 10 and constant head tank 20 respectively, can't install or the dismouting to paddle and motor smoothly this moment. Therefore, the carrier plate 1 needs to be driven to reciprocate up and down relative to the adapter plate 2 by the up-and-down movement of the lifting cylinder. Taking the installation of the blade and the motor as an example, when the lifting cylinder moves downwards, the carrier plate 1 will approach the adapter plate 2, and at this time, the positioned blade or the preset portion of the motor can protrude out of the contour groove 10 (the height of the carrier plate 1, the adapter plate 2, the matching surface 112, the contour groove 20, and the acting force provided by the preset component can be correspondingly controlled, such as protruding the blade out of the contour groove 20, or protruding the preset portion of the motor out of the contour groove 20), so as to facilitate the installation of the blade and the motor, after a batch of paddles and motors are positioned and mounted, by releasing the motor from the positioning slot 20, can take away paddle and the motor that the installation was accomplished, at this moment, lift cylinder can the upward movement jack-up support plate 1, and support plate 1 resets to keeping away from the state after relative keysets 2, can continue the unloading and fix a position and install paddle and the motor of next batch.

Optionally, in this embodiment of the application, the second mounting portion 11 of the carrier plate 1 may be disposed in a central region of the carrier plate 1, and correspondingly, the cylinder lifting groove 21 on the adapter plate 2 may be disposed in the central region of the adapter plate 2, so as to maintain the balance of the force of the preset component on the carrier plate 1, which is beneficial to protecting the paddle and the lifting cylinder.

Fig. 4 is an exploded schematic view of the positioning fixture described in this application, and as shown in fig. 4, optionally, in this application embodiment, the preset component may also be an elastic component 22, a third mounting portion 24 for fixing the elastic component 22 may be disposed on the interposer 2, a lower end of the elastic component 22 is placed or fixed in the third mounting portion 24, and an upper end of the elastic component 22 is supported against the bottom of the carrier plate 1; the third mounting portion 24 may have a sinking groove structure, and of course, in other embodiments of the present application, the third mounting portion 24 may have other structures as long as the elastic member 22 can be positioned, which is not limited in the embodiments of the present application.

Taking the installation of the paddle and the motor as an example for explanation, after the carrier board 1 is pressed down under the driving of external pressure, the elastic component 22 makes the carrier board 1 approach to the adapter board 2 due to compression, at this time, the preset part of the paddle or the motor which has been positioned can protrude out of the contour groove 10 to facilitate the installation of the paddle and the motor, after a batch of paddles and motors are positioned and installed, the paddle and the motor which have been tested can be taken away by releasing the fixation of the motor and the positioning groove 20, and the external pressure can be released, at this time, after the external pressure disappears, the compressed elastic component 22 can give a resilience force to the carrier board 1 above the elastic component based on the third installation part 24 at the bottom, so that the carrier board 1 can automatically reset to a far away state relative to the adapter board 2, thereby the circular up-and-down reciprocating motion of the carrier board 1 relative to the adapter board 2 can be realized under the, and continuously blanking to position and install the next batch of blades and motors.
