[0020] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other
[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification
[0022] As Figures 1-3 shown, an in-machine inner push fixture for facilitating die replacement includes a fixture body 1. A sunk groove 3 is formed on the surface of the fixture body 1 at the workpiece placement position. A bottom panel 7 is slidably installed in the sunk groove 3. The bottom panel 7 can be lifted. By lifting the bottom panel 7 to drive the top panel 2 to rise, the components on the surface of the top panel 2 and the fixture body 1 can be staggered, so as to ensure that when the workpiece is placed on the top panel 2, it will not be interfered by other components. At both ends of any one side of the adjacent sides at one corner of the top panel 2, extension seats 12 are fixedly connected. The top edge of the extension seat 12 on one side is provided with a first stop block 13 penetrating through it, and the top edge of the extension seat 12 on the other side is provided with a second stop block 17 penetrating through it. One side of each of the first stop block 13 and the second stop block 17 is slidably connected to the side of the top panel 2. A long connecting rod 10 is installed between the bottom surfaces of the two first stop blocks 13, and a short connecting rod 16 is installed between the bottom surfaces of the two second stop blocks 17. During actual use, by lifting the long connecting rod 10, the first stop block 13 cooperating with it is driven to rise, and by moving the short connecting rod 16, the second stop block 17 cooperating with it is forced to rise. By using the rising first stop block 13 and second stop block 17, it is ensured that when the workpiece is placed on the top panel 2, it is interfered by the first stop block 13 and the second stop block 17, and the workpiece is assisted in positioning, that is, the workpiece first slides along the surface of the first stop block 13 until it contacts the second stop block 17, which means that the workpiece is installed in place, facilitating the installation of the die
[0023] In addition: An electric push rod 8 is fixedly connected to the bottom edge of the jig body 1. The telescopic end of the electric push rod 8 observes the jig body 1 and extends to be fixedly connected to the bottom edge of the bottom panel 7. The extension seat 12 is inserted and connected to the side wall of the sunken groove 3. By extending the electric push rod 8 in this solution, the bottom panel 7 can be raised. The insertion of the extension seat 12 into the inner wall of the sunken groove 3 is to ensure that when the top panel 2 is located in the sunken groove 3, the extension seat 12 can be accommodated.
[0024] Furthermore: A top panel 2 with a clearance fit is fixedly connected to the top surface of the bottom panel 7, and an installation cavity 9 is formed in the clearance between the bottom panel 7 and the top panel 2. A plurality of lifting shells 4 extending into the installation cavity 9 are penetrated through the upper surface of the top panel 2. The side of the lifting shell 4 is inserted and connected to the top of the installation cavity 9, and a plurality of connecting seats 5 are fixedly connected to the bottom of the inner shell of the lifting shell 4. The top end of the connecting seat 5 is embedded and rotatably connected with a ball 6 which is misaligned with the top surface of the lifting shell 4. By raising the lifting shell 4 so that the balls 6 inside are higher than the upper surface of the top panel 2, it is ensured that when the workpiece is placed on the top panel 2 and its position is adjusted, due to the contact between the workpiece and the balls 6 and the rotation of the balls 6, the friction is reduced, facilitating the operator to push and adjust the position of the workpiece; A connecting plate 14 is penetrated through the connection between the bottom panel 7 and the top panel 2. A triangular block 15 is fixedly installed at a position on the connecting plate 14 close to the lifting shell 4. The hypotenuse of the triangular block 15 is slidably connected to the side of the bottom of the lifting shell 4. One side of the connecting plate 14 extends outward and is fixedly connected to the surface of the short connecting rod 16, and an electric push rod 8 is also fixedly installed between one side of the connecting plate 14 and the top panel 2. By telescoping the electric push rod 8 in this solution, the connecting plate 14 can slide along a fixed direction under the limiting effect of the penetration, as Figure 3 shown. When the connecting plate 14 slides to the left, the triangular block 15 on its surface also moves to the left. During the movement, the lifting shell 4 is raised by the contact between the hypotenuse of the triangular block 15 and the bottom edge of the lifting shell 4. Conversely, when the triangular block 15 moves to the right, the lifting shell 4 descends under the action of gravity. A dial block 11 fixedly connected to the outer side of the lifting shell 4 is lapped with the bottom surface of the long connecting rod 10. The long connecting rod 10 penetrates through the connection between the bottom panel 7 and the top panel 2. In addition, when the connecting plate 14 moves to the left, the short connecting rod 16 is also driven to move to the left. In addition, when the lifting shell 4 rises, the dial block 11 drives the long connecting rod 10 to rise, so that the first stop block 13 and the second stop block 17 rise with the rise of the lifting shell 4.
[0025] Working principle: When placing the workpiece, first, the electric push rod 8 on the fixture body 1 extends to raise the bottom panel 7 and the top panel 2 by a certain height. Then, the electric push rod 8 in the installation cavity 9 contracts to move the connecting plate 14 to the left, thereby raising the lifting shell 4, the first stop block 13, and the second stop block 17. The operator places the workpiece on the top panel 2. With the lifting effect of several ball bearings 6 and the guiding and limiting effects of the first stop block 13 and the second stop block 17, the workpiece can be smoothly and quickly placed at the corresponding position on the top panel 2. Then, the electric push rod 8 in the installation cavity 9 extends to reset the connecting plate 14, thereby lowering the lifting shell 4, the first stop block 13, and the second stop block 17 to their original positions, that is, the workpiece contacts the upper surface of the top panel 2. Then, by contracting the electric push rod 8 on the fixture body 1, the top panel 2 can be lowered to drive the workpiece to reach the upper surface of the fixture body 1.
[0026] The wiring diagram of the electric push rod 8 in the present utility model belongs to the common knowledge in the art. Its working principle is a well-known technology, and its model is selected according to actual use. Therefore, the control method and wiring layout of the electric push rod 8 will not be explained in detail.
[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
