DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a magnetic cover plate positioning tooling with a pneumatic ejection structure, comprising an installation carrier 1, an adjusting turntable 2, a transmission screw 3, a first slider 4, a first magnet 5, a supporting slider 6, a limiting clamp 7, a second magnet 8, a second slider 9, a first piston column 10, an air guide groove 11, a second piston column 12, a positioning suction cup 13 and an auxiliary ejection block 14. The installation carrier 1 is provided with a groove on its surface, the lower end of the rotating shaft of the adjusting turntable 2 is fixedly connected to the upper end of the rotating shaft of the transmission screw 3, and the thread directions of the outer surfaces at both ends of the transmission screw 3 are opposite, the first slider 4 is threadedly connected to the upper end of the transmission screw 3, and the first slider 4 is slidingly connected to the installation carrier 1. When using this device, first place the raw material in the groove on the surface of the installation carrier 1, and then rotate the two adjusting turntables 2, so that the adjusting turntable 2 drives the transmission screw 3 to rotate, and the first slider 4 is driven to slide down through the thread on the upper end of the transmission screw 3, so that the first slider 4 drives the first magnet 5 to approach the second magnet 8.

[0031] An opening is provided on the upper surface of the mounting carrier 1, and two adjusting dials 2 are rotatably connected to the inner wall of the opening of the mounting carrier 1, and two transmission screws 3 are rotatably connected to the inner wall of the opening of the mounting carrier 1. The magnetic poles of the first magnet 5 and the second magnet 8 facing each other are the same. A spring is connected between the supporting slider 6 and the mounting carrier 1, and an anti-slip rubber is provided on the surface of the limiting clamp 7. The second magnet 8 is repelled by the first magnet 5, so that the second magnet 8 drives the supporting slider 6 and the limiting clamp 7 to slide after being repelled, so that the two limiting clamps 7 clamp and limit the raw material, thereby improving the stability during processing. At the same time, the thread at the lower end of the transmission screw 3 drives the second slider 9 to slide up, and the second slider 9 drives the first piston column 10 to slide through the air guide groove 11 to extract the air at the lower end of the second piston column 12.

[0032] A first slider 4 is installed on the outer surface of the upper end of the transmission screw 3, and the anti-slip ejection mechanism includes a second slider 9, which is installed on the outer surface of the lower end of the transmission screw 3. The lower surface of one end of the second slider 9 is fixedly connected with a first piston column 10, and the surface of the mounting carrier 1 is provided with an opening, and the bottom surface of the opening of the mounting carrier 1 is slidably connected with a second piston column 12, and the second piston column 12 and the first piston column 10 are provided with an air guide groove 11, and a positioning suction cup 13 is fixedly connected to the opening surface of the mounting carrier 1, and an auxiliary ejection block 14 is fixed on the upper end of the second piston column 12, so that the second piston column 12 is driven to slide down. When the raw material is in contact with the positioning suction cup 13, the sliding of the second piston column 12 will cause a negative pressure between the positioning suction cup 13 and the raw material, thereby adsorbing and fixing the raw material, further increasing the anti-slip performance. When the raw material needs to be disassembled, the rotating disk 2 and the transmission screw 3 are reversed to make the transmission screw 3 drive the first slider 4 and the first magnet 5 away from the second magnet 8, so that the spring of the mounting carrier 1 pulls the support slider 6 and the limiting clamp 7 to slide and release the raw material.

[0033] The side surface of the first slider 4 is fixedly connected with the first magnet 5, the inner wall of the groove of the mounting carrier 1 is provided with an opening, and a supporting slider 6 is slidably connected in the opening of the groove of the mounting carrier 1, one end of the supporting slider 6 is fixedly connected with a limiting clamp 7, and the end of the limiting clamp 7 facing the first magnet 5 is fixedly connected with a second magnet 8, and an anti-slip ejection mechanism is provided inside the mounting carrier 1, which pushes air toward the second piston column 12 through the first piston column 10 to make it slide and then ejects the raw material through the auxiliary ejection block 14, the second slider 9 is threadedly connected to the lower end of the transmission screw 3, the length of the first piston column 10 is greater than the second piston column 12, and the second piston A spring is connected between the column 12 and the inner wall of the mounting carrier 1, the air guide groove 11 is a forked design, the positioning suction cup 13 is penetrated by the second piston column 12, and the auxiliary top block 14 is a block made of rubber. When the adjustment dial 2 and the transmission screw 3 are reversed, the transmission screw 3 drives the second slider 9 and the first piston column 10 to slide down, so that the first piston column 10 pushes the air to the second piston column 12 through the air guide groove 11, which makes it easier for the positioning suction cup 13 to lose its adsorption force. At the same time, the upper end of the second piston column 12 extends the positioning suction cup 13, and the raw material is pushed out by the auxiliary top block 14 at the upper end of the second piston column 12, thereby improving the efficiency of disassembling and unloading of the device.

[0034] Working principle: when using the magnetic cover positioning tooling with a pneumatic ejection structure, first place the raw material in the groove of the mounting carrier 1, then rotate the adjusting dial 2 to drive the transmission screw 3 to rotate, so that the transmission screw 3 drives the first slider 4 and the first magnet 5 to slide close to the second magnet 8, and the second magnet 8 is repelled and drives the supporting slider 6 and the limiting clamp 7 to slide to clamp and limit the raw material. At the same time, the transmission screw 3 drives the second slider 9 and the first piston column 10 to rise, so that the positioning suction cup 13 negative pressure adsorbs the raw material. When disassembling the raw material, the transmission screw 3 is reversed, so that the transmission screw 3 drives the first slider 4 and the first magnet 5 to slide away from the second magnet 8, which is convenient for the limiting clamp 7 to release the raw material. At the same time, the transmission screw 3 is reversed to drive the second slider 9 and the first piston column 10 to descend, so that the second slider 9 and the first piston column 10 descend, so that the first piston column 10 pushes the air to the second piston column 12 through the air guide groove 11, and then the second piston column 12 ejects the raw material through the auxiliary ejecting block 14, which increases the overall practicality.
