[0002] Negative pressure insulation panels are insulation boards produced on a vacuum negative pressure platform. The main body of a refrigerated truck is typically assembled from these panels. After production, the panels require hole-forming processing. However, existing hole-forming equipment has the following problems when processing negative pressure insulation panels:

[0003] 1. When existing drilling equipment drills holes in insulation boards, the drilling bit causes the insulation board to deviate at the moment of contact with the insulation board, which in turn causes the hole position to deviate from the preset position, affecting subsequent installation and use.

[0004] 2. Existing hole-forming equipment cannot standardize the hole depth on insulation boards during hole-forming, resulting in inconsistent hole depths and causing inconvenience for subsequent installation of the insulation boards. Utility Model Content

[0032] The installation and use process of the insulation board hole-forming fixture that integrates positioning and hole forming according to this utility model is as follows:

[0033] I. The installation process is as follows:

[0034] First, the installer can install the mounting frame assembly 1. Specifically, two sets of guide rods 12 can be installed on the upper part of the support base 11, with the bottom of the guide rods 12 connected to the support base 11. A top support 13 is installed on the top of the guide rods 12. Then, the movable bracket part 3 is installed. Specifically, the guide sleeve 31 can be slidably fitted onto the guide rod 12 through a smooth through hole, and the bracket body 33 is installed on the guide sleeve 31. A threaded sleeve 32 is installed on the bracket body 33, and the threaded sleeve 32 is connected to the lead screw body 24 through its threaded hole via a threaded engagement. The support guide rail is installed on the bracket body 33, and a slider is engaged on the guide rail. A movable support 4 is installed on the slider, and a hole-forming mechanism 5 is installed on the movable support 4. The hole-forming motor 51 is mounted on the movable support 4 via the docking seat 52. The drive shaft 53 is mounted on the hole-forming motor 51. The hole-forming tool 54 is mounted on the outer end of the drive shaft 53. Then, the top of the clamping spring 61 is mounted on the movable support 4. The clamping plate 62 is mounted on the bottom of the clamping spring 61. The clamping plate 62 has a through hole adapted to the hole-forming tool 54. Finally, the lead screw drive mechanism 2 is installed. Specifically, the motor seat 22 is mounted on the top support 13, the lead screw support 25 is mounted on the support base 11, the motor shaft is mounted on the drive motor 21, and the motor shaft is connected to the lead screw body 24 via the connecting sleeve 23. The other end of the lead screw body 24 is mounted on the lead screw support 25 via a bearing. Thus, the installation process of this utility model is completed.

[0035] In practical use, it can be divided into a pressing process and a hole-forming process:

[0036] 1. During the pressing process, the operator can place the perforated insulation board on the support base 11. Then, the drive motor 21 in the screw drive mechanism 2 can be started. The drive motor 21 (shaft) drives the screw body 24 to rotate clockwise through the connecting sleeve 23. At this time, under the action of the threaded force, the threaded sleeve 32 assembled on the screw body 24 drives the bracket body 33 to move downward. At this time, under the drive of the bracket body 33, the movable support 4 set on it drives the perforation mechanism 5 and the pressing mechanism 6 to move downward. Since the pressing mechanism 6 is located below the perforation mechanism 5, during the downward movement, the pressing plate 62 in the pressing mechanism 6 first contacts the upper surface of the insulation board. As the downward movement increases, the pressing spring 61 at the upper part of the pressing plate 62 pushes the pressing plate 62 to press and position the insulation board on the support base 11.

[0037] 2. During the hole-forming process, the operator can start the hole-forming motor 51 in the hole-forming mechanism 5. The hole-forming motor 51 can drive the hole-forming cutter 54 to rotate through the drive shaft 53. At the same time, the drive motor 21 in the lead screw drive mechanism 2 drives the lead screw body 24 to rotate clockwise. The threaded sleeve 32 drives the moving bracket part 3 to move down. At this time, the hole-forming mechanism 5 moves down under the drive of the moving bracket part 3. The compression spring 61 is further compressed. The hole-forming cutter 54 located on the lower side of the hole-forming mechanism 5 extends out from the through hole on the pressure plate 62 and contacts the compressed insulation board, and performs hole-forming operation on the insulation board.
