Abstract
Description
Technical Field
[0001] The utility model relates to the field of composite material products and sports goods, in particular to a double-sided clamping device for vacuum shaping of fillers inside fiber material products. Background Technique
[0002] Due to the fact that fiber materials such as carbon fiber and glass fiber are light and have good mechanical properties, they are used in various fields, such as the blades of wind turbines for wind power generation, surfboards, rudders, hockey sticks, etc. in sports goods, and aerospace products.
[0003] Due to the very good mechanical properties of fiber materials such as carbon fiber and glass fiber, only a few layers of materials are wrapped on the surface to meet the mechanical property requirements of the product. Therefore, fillers need to be added inside the product to support the shape and increase toughness. The fillers are generally low-density materials and are divided into multiple pieces. Fibrous materials are used between each piece and around them as stiffeners. In order to make the fibrous materials and the fillers more tightly connected and bonded, a vacuum machine is used to shape and press them. However, currently, only the upper and lower sides are pressed, and the side is not pressed. Only manually wrap the fibrous materials tightly, which will cause voids between each piece of the filler, dry yarn on the product surface, and sandwich yarn around the product shape, seriously affecting the quality of the product. Content of the Utility Model
[0004] The purpose of the utility model is to provide a double-sided clamping device for vacuum shaping of fillers inside fiber material products, so as to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A double-sided clamping device for vacuum shaping of fillers inside fiber material products, including a base and a clamping device. There are a base and 2 clamping devices. The base is a flat plate, and a plane similar to the shape of the product is made on the upper surface. A clamping device is installed on each side respectively. The clamping device includes an air tire, a clamping seat, an air inlet nozzle, an air release nozzle, a switch, a clamping soft rubber, 2 springs, and 2 distance-limiting screws. The clamping seat is installed on the upper surface of the base, and a left-side through groove is provided on the bottom surface to install the air tire. Distance-limiting screws are installed on the front and rear sides. A clamping soft rubber is installed on the left side. The air tire is fixed on the upper surface of the base, and is provided with an air inlet nozzle and an air release nozzle. Gas can be added through the air inlet nozzle and released through the air release nozzle. Its surface contacts the bottom surface of the through groove of the clamping seat and the right side surface of the clamping soft rubber, and can make the clamping soft rubber move to the left. One ends of the 2 distance-limiting screws are installed on both sides of the clamping seat respectively, and the other ends are installed on both sides of the clamping soft rubber, and springs are sleeved on the surfaces. The switch controls the opening and closing of the air inlet nozzle and the air release nozzle, so as to control the gas entering the air tire and being released from the air tire.
[0007] As a further solution of the present utility model: on the upper surface of the base, there are two adjustment slots on the left side for the left clamping seat to be adjusted left and right, and two adjustment slots on the right side for the right clamping seat to be adjusted left and right. There are two air nozzle holes on the right side surface.
[0008] As a further solution of the present utility model: the intake nozzle is connected to the left and right air tires, enabling gas to be added to the two air tires simultaneously.
[0009] As a further solution of the present utility model: the air release nozzle is connected to the left and right air tires, enabling gas to be released from the two air tires simultaneously.
[0010] As a further solution of the present utility model: the distance-limiting screw is divided into front and rear sections. The front section is continuous with one end of the clamping soft rubber, and one end of the front section is a sphere mounted on the clamping soft rubber.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: two clamping devices are used to clamp the filler, making the clamping of the filler firmer. Two air tires are used as the power of the clamping device, with a soft acting force, reducing the impact on the filler and preventing deformation. At the same time, the air pressure of the air tires can be adjusted through the intake nozzle, applying pressure from the side to reduce the occurrence of voids between each piece of the filler, dry yarn on the product surface, and yarn clamping around the product shape, etc., improving the yield rate and reducing costs.

The clamping device includes an air tire 4, a clamping seat 6, an air inlet nozzle 5, an air release nozzle 9, a switch 3, a clamping soft rubber 7, two springs 10, and two distance-limiting screws 8. The clamping seat 6 is installed on the upper surface 101 of the base 1, and an air tire 4 is installed in a left-side through groove on the bottom surface. Distance-limiting screws 8 are installed on the front and rear sides. A clamping soft rubber 7 is installed on the left side. The air tire 4 is fixed on the upper surface 101 of the base 1, and is provided with an air inlet nozzle 5 and an air release nozzle 9. Gas can be added through the air inlet nozzle 5 and released through the air release nozzle 9. Its surface contacts the bottom surface of the through groove of the clamping seat 6 and the right side surface of the clamping soft rubber 7, and can make the clamping soft rubber 7 move to the left. One end of each of the two distance-limiting screws 8 is installed on both sides of the clamping seat 6, and the other end is installed on both sides of the clamping soft rubber 7. Springs 10 are sleeved on the surface. The switch 35 controls the opening and closing of the air inlet nozzle and the air release nozzle 9, thereby controlling the gas to enter the air tire 4 and be released from the air tire 4.
[0021] For the base 1, two adjustment grooves 102 for enabling the left clamping seat 6 to be adjusted left and right are provided on the left side of the upper surface 101 of the base 1, and two adjustment grooves 103 for enabling the right clamping seat 6 to be adjusted left and right are provided on the right side. Two air nozzle holes are provided on the right side surface.
[0022] The air inlet nozzle 5 is connected to the left and right air tires 4, and can enable gas to be added to the two air tires 4 simultaneously.

[0024] The distance-limiting screw 8 is divided into front and rear sections. The front section 801 at the end continuous with the clamping soft rubber. One end of the front section is a sphere installed on the clamping soft rubber 7. When clamping, the sphere can rotate and become inclined, so that the clamping soft rubber 7 can be bent and is installed in the side holes 601 of the clamping seat 6.
[0025] The spring 10 can make the clamping soft rubber 7 move to the right.
[0026] The left top column 3 is fixed on the adjustment groove 102 of the base 1 with screws, and its position can be adjusted according to the shape of the filler 2.

[0028] The usage method of this utility model:
[0029] Place the filler 2 on the surface of the base 1 between the two clamping devices. When the vacuum machine works to vacuum-press the filler, press down. Press down the switch to turn it on, open the air inlet nozzle 5, and close the air release nozzle 11, so that gas is added into the two air tires 4 from the air inlet nozzle 5. At the same time, the air tires 4 push the two clamping soft rubbers 7 to move leftward to clamp the filler 2. When the vacuum machine finishes working and moves upward, turn off the switch, close the air inlet nozzle 5, open the air release nozzle 11, and the two air tires 4 deflate. The elastic force of the spring 10 moves the clamping soft rubber 7 to the right.
