[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 4As shown in the embodiment of this utility model, a plastic workpiece mounting and fixing device includes a support 1; a first electric push rod 11 is fixedly connected to the top of the support 1; a connecting block 12 is fixedly connected to the end of the first electric push rod 11; multiple second electric push rods 13 are fixedly connected to both sides of the connecting block 12; a fixing box 14 is fixedly connected to one side of the second electric push rod 13; multiple springs 15 are fixedly connected to the inner wall of the fixing box 14; and a fixing rod 16 is fixedly connected to the top of the springs 15. During operation, when it is necessary to fix the plastic workpiece, the connecting block 12 is moved to the top of the plastic workpiece. Then, by controlling the first electric push rod 11 to descend, the second electric push rods 13 are moved to the sides by controlling the connecting block 12. When the fixing box 14 descends until the fixing rods 16 are on both sides of the plastic workpiece, the fixing box 14 is moved inward by controlling the connecting block 12, so that the fixing rods 16 completely wrap around both sides of the plastic workpiece. Under the combined action of the springs 15 and the fixing rods 16, the workpiece is fixed by the fixing rods 16 adhering to the workpiece. Then, by controlling the connecting block 12, the second electric push rod 13 drives the fixing box 14 to move to both sides, so that the plastic workpiece is separated from the fixing rod 16, and the fixing of the plastic workpiece is released. By adding the fixing rod 16 and the spring 15, during the fixing process of the plastic workpiece, the plastic workpiece can be completely attached to the fixing rod 16 through the cooperation of multiple fixing rods 16 and springs 15, reducing the squeezing of the plastic workpiece. This reduces the problem of plastic workpiece displacement caused by the different external dimensions of various types of workpieces not being able to fit with the clamping structure during the fixing process.

[0026] like Figures 1 to 4 As shown, curved rods 2 are fixed to both sides of the fixed box 14; an elastic rope 21 is fixed to one side of the curved rod 2; the elastic rope 21 is located between the fixed rods 16; the curved rods 2 are evenly arranged on one side of the fixed box 14. During operation, when the plastic workpiece is completely in contact with the fixed rods 16, if the thickness of the plastic workpiece is less than the interval between the elastic ropes 21, the elastic ropes 21 will fix the plastic workpiece, preventing it from moving up and down. If the thickness of the plastic workpiece is greater than the interval between the elastic ropes 21, the plastic workpiece will contact the elastic ropes 21, causing the curved rods 2 to contract inwards, and the elastic ropes 21 to be stretched. The elastic ropes 21 that do not contact the plastic workpiece will fix the plastic workpiece, preventing it from moving up and down. By adding the curved rods 2 and the elastic ropes 21, the plastic workpiece can be fixed during installation, preventing it from moving up and down, thus addressing the problem of poor installation and fixing effect of the plastic workpiece.

[0027] like Figures 1 to 5As shown, multiple circular rubber pads 3 are fixed to the top of the fixing rod 16; the circular rubber pads 3 have a circular structure; and the spring 15 has a circular rubber pad 3 on one side. During operation, when the plastic workpiece is fully attached to the fixing rod 16, the circular rubber pads 3 will contact the plastic workpiece. The multiple circular rubber pads 3 provide cushioning, preventing close contact between the circular rubber pads 3 and the plastic workpiece, thus avoiding damage. By adding the circular rubber pads 3, the fixing rod 16 and the circular rubber pads 3 will not come into close contact with the plastic workpiece under pressure during the installation and fixing process, thus preventing damage to the plastic workpiece.

[0028] like Figures 1 to 6 As shown, a third electric actuator 4 is fixedly connected to the inner side of the fixed box 14; the third electric actuator 4 is slidably connected to a limiting plate 41; a vent pipe 42 is fixedly connected to one end of the third electric actuator 4; and multiple exhaust holes 43 are opened at the bottom of the vent pipe 42. During operation, when the plastic workpiece is completely attached to the fixing rod 16, the third electric actuator 4 extends forward through the limiting plate 41, and the third electric actuator 4 drives the vent pipe 42 to move forward to above the plastic workpiece. The air pump is then activated to introduce air into the vent pipe 42, which is then sprayed onto the plastic workpiece through the exhaust holes 43 to lower the temperature of the plastic workpiece. After cooling the plastic workpiece, the third electric actuator 4 is controlled to retract backward through the limiting plate 41, and the third electric actuator 4 drives the vent pipe 42 to move backward. By adding the vent pipe 42 and exhaust holes 43, the plastic workpiece can be cooled during installation and fixing, reducing the problem of deformation of the plastic workpiece due to high temperature during installation and fixing.

[0029] like Figures 1 to 6 As shown, a triangular cleaning block 5 is fixedly attached to the inner side of the fixed box 14; the triangular cleaning block 5 is in the shape of a triangular prism; the triangular cleaning block 5 is located at the bottom of the exhaust hole 43. During operation, by controlling the retraction and extension of the third electric actuator 4, the third electric actuator 4 drives the vent pipe 42 to move left and right, so that the exhaust hole 43 and the triangular cleaning block 5 come into contact back and forth, cleaning the dust accumulated around the exhaust hole 43; by adding the triangular cleaning block 5, the dust accumulated around the exhaust hole 43 can be cleaned, reducing the problem of dust accumulating around the exhaust hole 43 after the installation and fixing of plastic workpieces, which can cause the exhaust hole 43 to be blocked and prevent the exhaust hole 43 from cooling down.

[0030] like Figures 1 to 6As shown, a sponge pad 6 is fixedly attached to the surface of the vent pipe 42; the sponge pad 6 is located above the triangular cleaning block 5; the sponge pad 6 is located on one side of the third electric actuator 4. During operation, when the third electric actuator 4 is extended, it drives the vent pipe 42 forward, causing the two sides of the vent pipe 42 to collide with each other. At this time, the sponge pads 6 on both sides of the vent pipe 42 will form a buffer between the vent pipes 42. By adding the sponge pads 6, the collision between the vent pipes 42 can be buffered, reducing the problem of damage to the vent pipe 42 caused by the collision between the vent pipes 42.

[0031] During operation, when it is necessary to fix the plastic workpiece, the connecting block 12 is moved to the top of the plastic workpiece. Then, the first electric actuator 11 is lowered by controlling the connecting block 12, which in turn causes the second electric actuator 13 to move the fixing box 14 to both sides. When the fixing box 14 has descended to the point where the fixing rod 16 is on both sides of the plastic workpiece, the connecting block 12 is controlled to move the fixing box 14 inward, so that the fixing rod 16 completely covers both sides of the plastic workpiece. Under the combined action of the spring 15 and the fixing rod 16, the workpiece is fixed by the fixing rod 16 adhering to the workpiece. Then, by controlling the connecting block 12, the second electric push rod 13 drives the fixing box 14 to move to both sides, so that the plastic workpiece is separated from the fixing rod 16, and the fixing of the plastic workpiece is released. By adding the fixing rod 16 and the spring 15, during the fixing process of the plastic workpiece, the plastic workpiece can be completely attached to the fixing rod 16 through the cooperation of multiple fixing rods 16 and springs 15, reducing the squeezing of the plastic workpiece. This reduces the problem of plastic workpiece displacement caused by the different external dimensions of various types of workpieces not being able to fit with the clamping structure during the fixing process. When the plastic workpiece is fully attached to the fixing rod 16, if the thickness of the plastic workpiece is less than the interval between the elastic ropes 21, the elastic ropes 21 will fix the plastic workpiece, preventing it from moving up and down. If the thickness of the plastic workpiece is greater than the interval between the elastic ropes 21, the plastic workpiece will contact the elastic ropes 21, causing the arc rod 2 to contract inward and the elastic ropes 21 to stretch. The elastic ropes 21 that are not in contact with the plastic workpiece will fix the plastic workpiece, preventing it from moving up and down. By adding the arc rod 2 and elastic ropes 21, the plastic workpiece can be fixed during installation, preventing it from moving up and down, thus avoiding the problem of poor installation and fixation effect. When the plastic workpiece is fully attached to the fixing rod 16, the circular rubber pads 3 will contact the plastic workpiece. Multiple circular rubber pads 3 form a buffer for the plastic workpiece, preventing the circular rubber pads 3 from making close contact with the plastic workpiece and damaging it. By adding the circular rubber pads 3, the fixing rod 16 and the circular rubber pads 3 will not make close contact with the plastic workpiece under pressure during the installation and fixation process, thus preventing damage to the plastic workpiece. When the plastic workpiece is fully attached to the fixing rod 16, the third electric actuator 4 extends forward through the limiting plate 41. The third electric actuator 4 drives the vent pipe 42 forward to above the plastic workpiece, and the air pump is started to introduce air into the vent pipe 42. The air is then sprayed onto the plastic workpiece through the exhaust port 43 to lower the temperature of the plastic workpiece. After the plastic workpiece is cooled, the third electric actuator 4 is controlled to retract backward through the limiting plate 41, and the third electric actuator 4 drives the vent pipe 42 to move backward. By adding the vent pipe 42 and the exhaust port 43, the plastic workpiece can be cooled during installation and fixing, reducing the problem of deformation of the plastic workpiece due to high temperature during installation and fixing.By controlling the retraction and extension of the third electric actuator 4, the third electric actuator 4 drives the vent pipe 42 to move left and right, causing the exhaust port 43 to come into contact with the triangular cleaning block 5 back and forth, cleaning the dust accumulated around the exhaust port 43. By adding the triangular cleaning block 5, the dust accumulated around the exhaust port 43 can be cleaned, reducing the problem of dust accumulation around the exhaust port 43 after the plastic workpiece is installed and fixed, which could cause the exhaust port 43 to be blocked and unable to cool down. When the third electric actuator 4 is extended, the third electric actuator 4 drives the vent pipe 42 to move forward, causing the two sides of the vent pipe 42 to collide with each other. At this time, the sponge pads 6 on both sides of the vent pipe 42 will form a buffer between the vent pipes 42. By adding the sponge pads 6, the collision between the vent pipes 42 can be buffered, reducing the problem of damage to the vent pipe 42 caused by the collision between the vent pipes 42.
