[0030] Example 1

[0031] This embodiment provides a positioning device for surface layer processing, such as Figure 1 As shown, it includes a base 1, a symmetrically arranged lifting electric push rod 2 is fixedly installed on the top of the base 1, a positioning frame 3 is fixedly installed on the top of the lifting electric push rod 2, and a center processing table 6 is fixedly installed at the center of the top of the base 1. A foam insulation box is placed on the top of the center processing table 6, and the center processing table 6 is located at the center of the positioning frame 3.

[0032] like Figure 2 and 3 As shown, front and rear positioning components 4 are provided on the front and rear inner sides of the positioning frame 3, and left and right positioning components 5 are provided on the left and right inner sides of the positioning frame 3. By fully retracting the lifting electric push rod 2, the top surface of the positioning frame 3 is flush with the top surface of the center processing table 6 to facilitate the placement of the foam insulation box.

[0033] like Figure 3 As shown, the left and right positioning assembly 5 includes a lifting block 51, a screw 52, ​​a second electric push rod 53 and left and right positioning clamps 54. Both ends of the screw 52 are rotatably connected to the positioning frame 3. The lifting block 51 adopts an L-shaped structure. The screw 52 is threadedly connected to the lifting block 51 at the rod body. The second electric push rod 53 is fixedly installed on the side of the lifting block 51. Two lifting blocks 51 are provided, symmetrically arranged on the inner walls of the left and right sides of the positioning frame 3. The left and right positioning clamps 54 are fixedly installed at the ends of the second electric push rod 53. The lifting electric push rod 2 extends to lift the positioning frame 3, so that the second electric push rod 53 moves to the top of the central processing table 6, and the second electric push rods 53 on the sides of the two lifting blocks 51 extend, so that the two left and right positioning clamps 54 move toward each other to push the foam insulation box to position it.

[0034] like Figure 3 As shown, a pressure sensor 55 is fixedly installed at the center of the left and right positioning clamps 54, and a micro motor is fixedly installed at the end of the screw 52. The pressure sensor 55 is electrically connected to the micro motor and the second electric push rod 53 through a controller, and the micro motor is fixedly installed inside the positioning frame 3.

[0035] The pressure sensor 55 at the center of the left and right positioning clamps 54 detects the pressure to prevent the foam insulation box from being subjected to excessive pressure and deformation and damage. When the pressure on the left and right positioning clamps 54 reaches the set value, the second electric push rod 53 converts the electrical signal into a digital signal and transmits it to the controller. The controller contracts the lifting electric push rod 2 to move the positioning frame 3 downward, and the micro motor drives the screw 52 to rotate, so that the lifting block 51 moves upward. When the lifting block 51 moves to the extreme position, the second electric push rod 53 extends from the top of the positioning frame 3. At this time, there are only left and right positioning clamps 54 around the foam insulation box to block it, reducing the blocked area.

[0036] like Figure 3 As shown, the left and right inner walls of the positioning frame 3 are provided with strip grooves, and the lifting block 51 slides in the strip grooves. The strip grooves prevent the lifting block 51 from rotating when the screw 52 rotates to lift the lifting block 51. The lifting block 51 is located at a distance between the positioning frame 3 and the center processing table 6, and the second electric push rod 53 is located at the distance between the positioning frame 3 and the center processing table 6.

[0037] In this embodiment, the positioning frame 3 is at the same height as the foam insulation box by extending the lifting electric push rod 2, and the second electric push rod 53 is extended to clamp the two left and right positioning blocks 54 to position the foam insulation box. The left and right positioning blocks 54 are subjected to pressure from the foam insulation box to reach a set value. At this time, the lifting electric push rod 2 contracts to move the positioning frame 3 downward, and the screw 52 rotates to move the lifting block 51 upward, and the second electric push rod 53 extends from the top of the positioning frame 3, reducing the blocking area of ​​the foam insulation box by the positioning device.

[0038] Example 2

[0039] Based on Example 1, this embodiment proposes a positioning device for surface layer processing, such as Figure 4 As shown, the front and rear positioning assembly 4 includes a first electric push rod 41, an extension plate 42, a front and rear positioning clamping block 43 and a contact switch 46. The two ends of the first electric push rod 41 are respectively connected to the positioning frame 3 and the extension plate 42. The side of the extension plate 42 is provided with a front and rear positioning clamping block 43. The contact switch 46 is fixedly installed on the side of the extension plate 42 facing the front and rear positioning clamping block 43. The contact switch 46 is electrically connected to the first electric push rod 41 through a controller. The first electric push rod 41 is extended to make the extension plate 42 and the front and rear positioning clamping block 43 move toward the foam insulation box, and the front and rear positioning clamping block 43 contacts the foam insulation box to move toward the extension plate 42. The front and rear positioning clamping block 43 contacts the contact switch 46. The contact switch 46 converts the electrical signal into a digital signal to the controller, and stops the extension of the first electric push rod 41 through the controller to prevent the first electric push rod 41 from further extending and causing the front and rear positioning clamping block 43 to crush the foam insulation box.

[0040] like Figure 4As shown, the side of the front and rear positioning clamps 43 away from the extension plate 42 is rotatably connected to the roller 44. When the two front and rear positioning clamps 43 clamp the foam insulation box, the second electric push rod 53 extends to make the left and right positioning clamps 54 push the foam insulation box. The roller 44 is used to reduce the friction between the front and rear positioning clamps 43 and the foam insulation box to avoid damage to the foam insulation box and facilitate the left and right positioning clamps 54 to push the foam insulation box. The front and rear positioning clamps 43 cooperate with the left and right positioning clamps 54 to position the foam insulation box in the center.

[0041] When performing surface processing, the first electric push rod 41 is first retracted to perform the steps in Example 1. Subsequently, the first electric push rod 41 is extended to allow the front and rear positioning clamps 43 to fix the position of the foam insulation box. At the same time, the second electric push rod 53 is retracted to remove the left and right positioning clamps 54 from the foam insulation box. The left and right positioning is performed first, and then the front and rear positioning is performed. The positioning is alternated to prevent the positioning device from blocking the foam insulation box.

[0042] A guide rod is fixedly mounted on the side of the front and rear positioning clamps 43, and the guide rod is slidably connected to the extension plate 42. A spring sheet 45 is elastically connected between the extension plate 42 and the front and rear positioning clamps 43, and two spring sheets 45 are provided and symmetrically distributed on the side of the extension plate 42. The spring sheet 45 is used to reset the front and rear positioning clamps 43, and the guide rod prevents the front and rear positioning clamps 43 from tilting when moving.

[0043] In this embodiment, the foam insulation box is first centrally positioned by the front and rear positioning clamps 43 and the left and right positioning clamps 54, and then the first electric push rod 41 is retracted to move the front and rear positioning clamps 43 away from the foam insulation box, and the front and back surface layers are processed. Then, the first electric push rod 41 is extended to clamp the foam insulation box with the front and rear positioning clamps 43, and then the second electric push rod 53 is retracted to separate the left and right positioning clamps 54 from the foam insulation box, and then the left and right surface layers are processed. Alternate positioning is performed to prevent positioning from blocking the surface layer processing of the foam insulation box.

[0044] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
