Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing, in particular to a rubber pad pressing mechanism. Background Art

[0002] A Chinese utility model patent, with authorization publication number CN 218716405 U, discloses a new type of door and window sealing rubber gasket, which consists of a door and window body, a sealing gasket, a sealing groove, a sealing gasket and a welding strip. By setting the sealing gasket, the entire sealing gasket is welded in the sealing groove by the welding strip, replacing the traditional glue bonding to prevent the sealing gasket from slipping out of the sealing groove over time. The first rubber gasket, the second rubber gasket and several rubber columns all seal the gap of the sealing groove, and the insulation board blocks the heat generated by the welding of the welding strip, thereby extending the service life of the sealing gasket and ensuring the overall sealing of the door and window.

[0003] In the above solution, the rubber pad needs to be pressed into the sealing groove manually. Since the sealing pad and the sealing groove are interference fit, this will inevitably waste a lot of manpower. Therefore, a rubber pad pressing mechanism is proposed to solve the above problem. Utility Model Content

[0004] The purpose of the present invention is to provide a rubber pad pressing mechanism to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a rubber pad pressing mechanism, comprising a base plate and a controller, a linear motor being provided on one side of the base plate, a movable block being provided on the other side, a top plate being fixed between the linear motor and the movable block, two fixed plates being fixed on the top end of the base plate, and a door and window body being placed between the two fixed plates;

[0006] Two positioning components are provided between the two fixing plates, and driving parts are provided on the outside of the positioning components. The door and window body is limited between the two fixing plates by the positioning components;

[0007] A pressing assembly is provided at the bottom of the top plate. The pressing assembly includes an electric telescopic rod. A horizontal plate is fixed to the telescopic end of the electric telescopic rod.

[0008] Preferably, the positioning assembly includes a double-ended screw and a limiting rod, and the threads on the rod bodies on both sides of the double-ended screw are in opposite directions;

[0009] Both sides of the double-headed screw rod are movably screwed with sliders, and the sliders are movably plugged into the limit rods;

[0010] When the double-ended screw rotates, it drives the two sliders to move toward or away from each other.

[0011] Preferably, the driving member includes a gear fixed to the end of the double-headed screw, an internally toothed belt is provided between the two gears, and the inner teeth of the internally toothed belt are meshed with the gear.

[0012] Preferably, an elastic pad is fixed on the inner side of the slider.

[0013] Preferably, the clamping assembly further comprises a plurality of socket pipes fixed to the bottom end of the transverse plate, wherein an inserting shaft is movably inserted into the socket pipe, and a pressure block is fixed to the bottom end of the inserting shaft;

[0014] A top block is fixed on the top of the plug shaft, and a spring is connected between the top block and the inner wall of the bottom of the socket pipe.

[0015] Preferably, a pressure sensor is fixed to the inner wall of the top end of the bell pipe.

[0016] Preferably, a distance measuring sensor is provided on the right side of the horizontal plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The rubber pad pressing mechanism is provided with a positioning component, a pressing component, a distance sensor and a pressure sensor. The door and window body is fixed in the center on the top of the bottom plate through the positioning component, and the rubber pad is manually placed in the sealing groove. After the placement is completed, the controller controls the linear motor to drive the pressing component to move laterally. When the distance sensor detects the rubber pad, the controller controls the linear motor to stop, and then controls the pressing component to press the rubber pad until the top block and the pressure sensor are squeezed. When the pressure on the pressure sensor reaches the set value, the controller controls the electric telescopic rod to retract, and so on, to complete the pressing of all rubber pads. The device realizes the automatic installation of rubber pads and reduces manpower consumption.

[0019] In addition, after the rubber pad is manually placed in the sealing groove at the top of the door and window body, the rubber pad on one side may be higher than the rubber pad on the other side. When pressed, the pressure block on the top of the protruding rubber pad first contacts the rubber pad. Since the contact area between the pressure block and the rubber pad is small, the friction between the rubber pad and the inner wall of the sealing groove at the top of the door and window body is small, which makes it convenient to press the protruding rubber pad into the sealing groove so that the top surface of the rubber pad is parallel to the top surface of the door and window body, and then facilitates the rubber pad to enter the sealing groove when the pressing assembly is continuously pressed, which solves the problem of uneven pressing force caused by manual installation, which may cause the rubber pad to be uneven after installation, thereby affecting product quality.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a rubber pad pressing mechanism, including a base plate 1 and a controller, a linear motor is provided on one side of the base plate 1, and a movable block is provided on the other side, and a top plate 2 is fixed between the linear motor and the movable block. After the controller starts the linear motor, the linear motor drives the top plate 2 to move along the side of the base plate 1, and two fixed plates 4 are fixed at the top of the base plate 1, and the door and window body 6 is placed between the two fixed plates 4.

[0026] Two positioning components 5 are provided between the two fixing plates 4. A driving member is provided on the outside of the positioning components 5. The door and window body 6 is limited between the two fixing plates 4 by the positioning components 5.

[0027] Specifically, the positioning assembly 5 includes a double-headed screw rod 501 and a limit rod 502. The double-headed screw rod 501 is movably connected to the two fixed plates 4. The fixed plate 4 extends from one side of the double-headed screw rod 501. The threads on the rod bodies on both sides of the double-headed screw rod 501 are in opposite directions. Sliders 503 are movably screwed on both sides of the double-headed screw rod 501. The sliders 503 are movably plugged into the limit rod 502. The setting of the limit rod 502 ensures that the double-headed screw rod 501 can drive the two sliders 503 to move toward or away from each other along the direction of the limit rod 502 when rotating, thereby realizing the limitation or release of the door and window body 6.

[0028] like Figure 2As shown, the driving member includes a gear 505 fixed to the end of the double-headed screw 501, and an internally toothed belt 506 is arranged between the two gears 505. The inner teeth of the internally toothed belt 506 are engaged with the gear 505. A handle 507 is fixed on the top of the internally toothed belt 506. By pulling the handle 507, the internally toothed belt 506 is rotated, thereby realizing the synchronous rotation of the two double-headed screws 501. In order to prevent damage to the side of the door and window body 6 when clamping the door and window body 6, an elastic pad 504 is fixed on the inner side of the slider 503.

[0029] It can be known that the driving member can also be a knob fixed at the end of the double-ended screw 501, that is, the double-ended screw 501 is driven to rotate by the knob, but this requires the double-ended screws 501 on both sides to be rotated separately, which consumes a lot of manpower and the clamping force cannot be guaranteed to be consistent.

[0030] like Figure 2 and Figure 3 As shown, a clamping assembly 3 is provided at the bottom of the top plate 2, and the clamping assembly 3 includes an electric telescopic rod fixed to the top plate 2, and the telescopic end of the electric telescopic rod is fixed to the cross plate 301. In addition, the clamping assembly 3 also includes a plurality of socket pipes 303 fixed to the bottom end of the cross plate 301. In a specific embodiment of the present scheme, four socket pipes 303 are provided, distributed at the four corners of the bottom end of the cross plate 301, and an insertion shaft 304 is movably inserted in the socket pipe 303, and a pressure block 305 is fixed to the bottom end of the insertion shaft 304, and a top block 306 is fixed to the top of the insertion shaft 304, and a spring 307 is connected between the top block 306 and the bottom inner wall of the socket pipe 303.

[0031] It should be noted that after the rubber pad is manually placed in the sealing groove at the top of the door and window body 6, the rubber pad on one side may be higher than the rubber pad on the other side. When pressing, the controller controls the electric telescopic rod to extend, and the electric telescopic rod drives the pressure block 305 to move downward. The pressure block 305 on the top of the protruding rubber pad first contacts the rubber pad. During the extrusion process, the spring 307 contracts. Since the contact area between the pressure block 305 and the rubber pad is small, the friction between the rubber pad and the inner wall of the sealing groove at the top of the door and window body 6 is small, which makes it convenient to press the protruding rubber pad into the sealing groove, so that the top surface of the rubber pad is parallel to the top surface of the door and window body 6, and it is convenient for the rubber pad to enter the sealing groove completely when the pressing component 3 is continuously pressed.

[0032] In order to realize automatic control of the device, a pressure sensor 308 is fixed on the inner wall of the top end of the bell pipe 303 , and a distance sensor 302 is provided on the right side of the cross plate 301 .

[0033] To supplement this solution, when in use, the door and window body 6 is placed between the fixed plates 4, and the door and window body 6 is centered and limited at the top of the bottom plate 1 through the positioning component 5. At this time, the door and window body 6 is located directly below the horizontal plate 301, and the rubber pad is manually placed in the sealing groove. After placement is completed, the controller controls the linear motor to drive the clamping component 3 to move horizontally. When the ranging sensor 302 detects the rubber pad (existing technology), the controller controls the linear motor to stop, and then the controller controls the clamping component 3 to press the rubber pad until the top block 306 is squeezed with the pressure sensor 308. When the pressure on the pressure sensor 308 reaches the set value, the controller controls the electric telescopic rod to retract, and so on, to complete the clamping of all rubber pads.

[0034] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
