Description

Technical Field

[0001] This utility model relates to the technical field of plastic panel processing equipment, specifically a four-corner positioning component for processing plastic panels. Background Technology

[0002] In the construction industry, on-site safety is a crucial aspect of ensuring the safety of construction workers and the smooth progress of projects. Plastic hoardings, as an important protective facility, are widely used in construction site enclosures and isolations due to their advantages such as light weight, corrosion resistance, easy installation, and reusability. Plastic hoardings can effectively separate construction areas from non-construction areas, preventing unauthorized personnel from accidentally entering dangerous construction zones, while also reducing the impact of dust and noise generated during construction on the surrounding environment.

[0003] In the processing of plastic hoardings for construction, pre-drilling positioning is a crucial step to ensure the assembly accuracy of the hoardings. However, current positioning methods for plastic hoardings have significant shortcomings. Existing positioning methods mostly rely on manual adjustment or simple positioning devices. These methods are difficult to guarantee the stability of the plastic hoardings during the positioning process, and the position is prone to deviation. This deviation will further transmit to the subsequent drilling process, resulting in inaccurate drilling positions, which seriously affects the assembly effect and overall quality of the plastic hoardings. Therefore, we need to propose a four-corner positioning component for plastic hoarding processing. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A four-corner positioning assembly for processing plastic sheets includes: a base 1 and a synchronous transmission mechanism. The synchronous transmission mechanism is installed at the bottom of the base 1. A first movable seat 8, a second movable seat 9, a third movable seat 15 and a fourth movable seat 16 are installed on the synchronous transmission mechanism. A first fixed seat 18 is installed on the top of the first movable seat 8 and the second movable seat 9. A second fixed seat 21 is installed on the top of the third movable seat 15 and the fourth movable seat 16. The first fixed seat 18 and the second fixed seat 21 are slidably installed on the base 1.

[0024] The tops of the first fixing seat 18 and the second fixing seat 21 are symmetrically fixed with two sets of fixing seats 14, and the sides of the fixing seats 14 are fitted with clamping plates 19 for holding the plastic panel.

[0025] In an optional embodiment: such as Figures 2 to 3As shown, the synchronous transmission mechanism includes a fixed plate 2, a drive motor 3, a double-acting lead screw 4, a first bevel gear 5, a first adjusting lead screw 6, a second adjusting lead screw 7, a second bevel gear 11, and a third bevel gear 17. The fixed plate 2 is fixedly installed on the bottom of the base 1, the drive motor 3 is fixedly installed on the side of the fixed plate 2, and the output shaft of the drive motor 3 is fixedly connected to the double-acting lead screw 4 through a coupling. The first bevel gear 5 is fixedly connected to the double-acting lead screw 4, the first moving seat 8 is threaded on the left-hand thread of the double-acting lead screw 4, and the second moving seat 9 is threaded on the right-hand thread of the double-acting lead screw 4.

[0026] Both the first adjusting screw 6 and the second adjusting screw 7 are movably mounted on the bottom of the base 1. The second bevel gear 11 is fixedly connected to the end of the first adjusting screw 6, and the third bevel gear 17 is fixedly connected to the end of the second adjusting screw 7. Both the second bevel gear 11 and the third bevel gear 17 mesh with the first bevel gear 5. The third moving seat 15 is threaded onto the first adjusting screw 6, and the fourth moving seat 16 is threaded onto the second adjusting screw 7.

[0027] It should be noted that, through the cooperation of the drive motor 3, the bidirectional lead screw 4, the first bevel gear 5, the first adjusting lead screw 6, the second adjusting lead screw 7, the second bevel gear 11, and the third bevel gear 17, the first moving seat 8, the second moving seat 9, the third moving seat 15, and the fourth moving seat 16 can be driven to approach the plastic panel. This allows the abutment plate 19 on the first fixed seat 18 and the second fixed seat 21 to push and adjust the position of the plastic panel, thereby centering the plastic panel and clamping and fixing it with the abutment plate 19.

[0028] In an optional embodiment: such as Figures 2 to 3 As shown, the bottom of the base 1 is symmetrically and fixedly equipped with multiple sets of guide rails 10 for positioning. The first movable seat 8, the second movable seat 9, the third movable seat 15 and the fourth movable seat 16 are all slidably mounted on the guide rails 10.

[0029] It should be noted that the guide rail 10 serves to guide the first movable seat 8, the second movable seat 9, the third movable seat 15, and the fourth movable seat 16, enabling them to move stably.

[0030] In an optional embodiment: such as Figure 1 and Figure 4 As shown, a pressure sensor 20 is fixedly installed inside the mounting base 14, and a clamping plate 19 is fixedly installed on the detection end of the pressure sensor 20.

[0031] It should be noted that the pressure sensor 20 can detect the clamping force on the plastic panel, preventing the plastic panel from deforming or being damaged due to excessive clamping force, thus protecting the plastic panel.

[0032] The drive motor 3 is set as a servo motor with a brake, which can prevent the first moving seat 8, the second moving seat 9, the third moving seat 15 and the fourth moving seat 16 from being displaced due to loss of power under the influence of the reaction force of the plastic panel or their own weight.

[0033] Specifically, when the equipment is working normally, the brake of the servo motor is in the released state, which does not affect the rotation of the motor output shaft and the movement of each transmission component, ensuring that the clamping plate 19 can smoothly complete the clamping or releasing action on the plastic panel. However, in the event of a power failure, the brake device of the servo motor will immediately activate and lock the motor output shaft, preventing the bidirectional lead screw 4, the first adjusting lead screw 6, and the second adjusting lead screw 7 from rotating freely.

[0034] A controller is fixedly installed on the top of the base 1, and the drive motor 3 and the pressure sensor 20 are electrically connected to the controller.

[0035] In an optional embodiment: such as Figure 2 As shown, the top of the base 1 is integrally formed with a placement plate 12 for placing the plastic enclosure. The top of the placement plate 12 has multiple sets of clearance through holes 13 corresponding to the drilling positions of the plastic enclosure.

[0036] It should be noted that, through the multiple sets of clearance through holes 13 on the placement plate 12, when the drilling equipment is drilling holes in the plastic enclosure, the drill bit of the drilling equipment can be inserted into the clearance through holes 13 after drilling the plastic enclosure, so as to prevent the drill bit from contacting the placement plate 12 and being damaged.

[0037] The usage process of this utility model is as follows: Place the plastic enclosure on top of the placement plate 12. Start the drive motor 3 through the controller. The output shaft of the drive motor 3 drives the bidirectional lead screw 4 to rotate. When the bidirectional lead screw 4 rotates, it drives the first bevel gear 5 to rotate. The first bevel gear 5 drives the second bevel gear 11 and the third bevel gear 17 to rotate the first adjusting lead screw 6 and the second adjusting lead screw 7. When the bidirectional lead screw 4, the first adjusting lead screw 6 and the second adjusting lead screw 7 rotate, they drive the second moving seat 9, the first moving seat 8, the third moving seat 15 and the fourth moving seat 16 to move closer to the plastic enclosure. The second moving seat 9 and the first moving seat 8 drive the first fixed seat 18 to move. The third moving seat 15 and the fourth moving seat 16 drive the second fixed seat 21 to move. When the first fixed seat 18 and the second fixed seat 21 drive the abutment plate 19 to move closer to the plastic enclosure, it can be centered during the pushing and adjustment of the position of the plastic enclosure. In addition, the abutment plate 19 clamps and fixes the plastic enclosure.

[0038] When clamping and fixing the plastic panel, the pressure sensor 20 detects the force after clamping the plastic panel and transmits the detected force to the controller. When the clamping force detected by the pressure sensor 20 reaches the preset threshold, the controller will issue a command to stop the operation of the drive motor 3. This ensures that the clamping plate 19 forms a stable clamp on the plastic panel, preventing positional displacement during subsequent processing, and also prevents the plastic panel from deforming or being damaged due to excessive clamping force, thus protecting the plastic panel.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
