Detailed Description
As shown in fig. 1, the workpiece equalizing and pressing device comprises a base, wherein the base 1 is a basic component of the whole device, and other components are directly or indirectly arranged on the base 1.
A U-shaped bracket 2 is fixed on the base 1, the opening of the U-shaped bracket 2 faces downwards, and the top surface of the U-shaped bracket 2 is a horizontal plane in general.
The base 1 is further fixed with an air cylinder 3, a fixing plate 16 is arranged in the U-shaped support 1, two ends of the fixing plate 16 are fixedly connected with the U-shaped support 2 respectively, the bottom surface of the fixing plate is fixedly connected with the front end face of the air cylinder 3, and the fixing plate 16 is parallel to the base 1.
Therefore, the cylinder 3 can be firmly fixed between the base 1 and the fixing plate 16 by the base 1 and the fixing plate 16.
The cylinder 3 is provided with a top rod 4, the top rod 4 is inserted into the fixed plate 16 and extends out from the front end of the fixed plate 16, and the top end of the extended top rod 4 is hinged with a balance rod 13.
Two sliding holes 8 are formed in the U-shaped support 2, a pressing rod 12 is inserted into each sliding hole 8, a stud 11 is fixed to the top of each pressing rod 12, a pressing claw 9 is fixed to each stud 11, the pressing claws 9 are fixedly connected with the studs 11 through pressing nuts 10, pressing blocks 15 are fixed to the inner ends of the pressing claws 9, the two pressing rods 12, the two pressing claws 9 and the two pressing blocks 15 are symmetrical with respect to the central axis of the ejector rod 4, the bottom ends of the two pressing rods 12 are hinged to the left end and the right end of the balance rod 13 respectively, and the bottom ends of the two pressing rods 12 are hinged to the left end and the right end of the balance rod 13 respectively.
When it is desired to press the workpiece 14, the workpiece 14 is placed on the top surface of the U-shaped support 2, and the workpiece is also placed below the two pressing blocks 15. Therefore, when the cylinder 3 is started, the push rod 4 moves up and down, when the push rod 4 moves down, the balance rod 13 is driven to move down, the balance rod 13 can pull the two pressing rods 12 to slide down along the sliding hole 8 while moving down, the pressing rods 12 can further drive the pressing claw 9 and the pressing block 15 to move down while sliding down, and the workpiece 14 can be pressed by the pressing block 15 and the pressing claw 9 moving down.
Similarly, when the top rod 4 moves upwards, the balance rod 13, the pressing rod 12, the pressing claw 9 and the pressing block 15 are further driven to move upwards, and the workpiece 14 is loosened.
