[0037] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0038] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0039] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0040] The embodiment of the present invention provides a pre-positionable cover plate fixture, such as Figure 2-5 As shown, the base plate 100 includes a plurality of support columns 200, a plurality of pressing assemblies 300 adapted to the support columns 200, a limiting assembly 400, a lifting assembly 500, a transverse pushing assembly 600, and a pre-positioning assembly 700. The plurality of support columns 200, the plurality of pressing assemblies 300 adapted to the support columns 200, the limiting assembly 400, the lifting assembly 500, the transverse pushing assembly 600, and the pre-positioning assembly 700 are all fixed to the base plate 10. The support columns 200 are used to support the cover plate 10; the pressing assemblies 300 are used to press the cover plate 10 against the support columns 200 to clamp and fix the cover plate 10; the limiting assembly 400 is located on the outer periphery of the cover plate 10 to limit the horizontal movement of the cover plate 10 and play a positioning role; the lifting assembly 500 is used to lift the cover plate 10 and clamp the cover plate 10 together with the pressing assembly 300. The horizontal pushing assembly 600 is used to push the cover plate 10 in the horizontal direction to clamp the cover plate 10 with the limiting assembly 400. The pre-positioning assembly 700 includes an elastic pin 710 located on the periphery of the cover plate 10 and elastically retractable in the horizontal direction. The elastic pin 710 is used to abut the cover plate 10.

[0041] When using the clamp of this embodiment, the cover plate 10 is placed on the support column 200. The limiting assembly 400 limits the cover plate 10 from the periphery. To smoothly insert the cover plate 10, the range limited by the limiting assembly 400 must be larger than the size of the cover plate 10, which may cause the cover plate 10 to become loose. The elastic pin 710 of this embodiment is elastically retractable. Under the action of elastic force, the elastic pin 710 will abut the cover plate 10, thereby pre-positioning the cover plate 10 and preventing it from loosening. The pressing assembly 300, the lifting assembly 500, and the horizontal pushing assembly 600 can act on the cover plate 10 at the ideal position to stably clamp the cover plate 10.

[0042] In some embodiments, the pre-positioning assembly 700 further includes a pin holder 720 fixed to the base plate 100. A horizontally extending pin hole is provided on the side of the pin holder 720. A spring is disposed within the pin hole. An elastic pin 710 is inserted into the pin hole. The ends of the spring abut against the elastic pin 710 and the inner wall of the pin hole, respectively. This allows the elastic pin 710 to elastically expand and contract along the axial direction of the pin hole. Furthermore, the pin hole guides the elastic pin 710, allowing it to stably move along the axial direction of the pin hole.

[0043] In some embodiments, the front side of the elastic pin 710 includes an abutment surface 712 and a guide surface 711. The guide surface 711 is located above and connected to the abutment surface 712. The guide surface 711 is arranged at an angle and gradually protrudes forward in the downward extending direction. The abutment surface 712 is used to abut the cover plate 10. During the process of lowering the cover plate 10, the outer periphery of the cover plate 10 will press the guide surface 711, thereby causing the elastic pin 710 to contract, facilitating the placement of the cover plate 10. When the cover plate 10 is in place, the abutment surface 712 abuts the cover plate 10 to provide a clamping force for the cover plate 10.

[0044] In some embodiments, as Figure 2 、 Figure 4 and Figure 6 As shown, the pressing assembly 300 includes a pressing rod 310 and a pressing rod driving mechanism 320. One end of the pressing rod 310 is connected to the pressing rod driving mechanism 320, and the other end is a lower pressing end 311. The pressing rod driving mechanism 320 is used to drive the lower pressing end 311 of the pressing rod 310 to press downward, and the support column 200 is located below the lower pressing end 311. When the pressing rod driving mechanism 320 drives the lower pressing end 311 of the pressing rod 310 to press downward, the lower pressing end 311 of the pressing rod 310 and the support column 200 jointly clamp and fix the cover plate 10.

[0045] In this embodiment, the pressure rod driving mechanism 320 may include an oil cylinder and a connecting rod mechanism, and drives the pressure rod 310 to rotate to achieve the downward pressure of the lower pressing end 311 thereof.

[0046] In some embodiments, as Figure 2 、 Figure 4 and Figure 7 As shown, the limiting assembly 400 includes a plurality of limiting blocks 410 . The limiting blocks 410 can abut against the outer side surface of the cover plate 10 , thereby limiting the cover plate 10 from moving in the horizontal direction.

[0047] The limiting block 410 may be provided with a notch 411 , which is adapted to the outer peripheral contour of the contact portion of the cover plate 10 . A portion of the cover plate 10 may be inserted into the notch 411 to better position the cover plate 10 .

[0048] In some embodiments, as Figure 2 、 Figure 4 and Figure 7 As shown, the lifting assembly 500 includes a lifting rod 510 and a lifting rod driving mechanism 520 connected to the lifting rod 510. The lifting rod driving mechanism 520 is used to drive the lifting rod 510 to lift upward to provide an upward lifting force and clamp the cover plate 10 together with the pressing assembly 300.

[0049] The push rod driving mechanism 520 may be a cylinder.

[0050] In some embodiments, as Figure 2 、 Figure 4 and Figure 8 As shown, the transverse push assembly 600 includes a transverse push rod 610, a transverse push seat 620, and a transverse push drive mechanism 630. The transverse push seat 620 and the transverse push drive mechanism 630 are both fixed to the base plate 100. The transverse push seat 620 is provided with a through-hole running through it in the horizontal direction. The transverse push rod 610 is passed through the through-hole and is connected to the transverse push drive mechanism 630. The transverse push drive mechanism 630 is used to drive the transverse push rod 610 to move in the horizontal direction. The transverse push rod 610 can push the cover plate 10, thereby further positioning the cover plate 10. The through-hole plays a guiding role for the transverse push rod 610, guiding the transverse push rod 610 to stably move along the axial direction of the through-hole.

[0051] The transverse thrust driving mechanism 630 includes an oil cylinder.

[0052] In some embodiments, as Figure 9 As shown, the pre-positionable cover plate fixture also includes a rotating seat 800 and a rotating assembly 900. One end of the base plate 100 is rotatably connected to the rotating seat 800, and the other end is connected to the rotating assembly 900. The rotating assembly 900 is used to drive the base plate 100 to rotate, thereby changing the orientation angle of the base plate 100, and correspondingly changing the angle of the cover plate clamped by the entire fixture to meet the processing angle requirements.

[0053] In this embodiment, the rotating assembly 900 may include a motor, and the output shaft of the motor is connected to the base plate 100 to drive the base plate 100 to rotate.
