The utility model discloses in a device is revised fast to movement casting die, including fixed column 10 and fixed briquetting 20. Specifically, refer to fig. 1, fig. 2 and fig. 3. Fig. 1 is a schematic view of a device for rapidly modifying a press part of a machine core of the present invention, fig. 2 is a schematic view of a fixing column of the present invention, and fig. 3 is a schematic view of a fixing press block of the present invention.
One end face of the fixed pressing block 20 is provided with a first round hole 21, and the other opposite end face is provided with a second round hole 22. The first circular hole 21 and the second circular hole 22 penetrate through the fixed pressing block 20 and are concentrically arranged. Preferably, the diameter of the second circular hole 22 is smaller than the diameter of the product placement table 13 and the first circular hole 21.
The fixing post 10 includes a base 11, a screw post 12, and a product placing table 13. The base 11 is arranged at one end of the fixed column 10. The threaded column 12 is arranged at the other end of the fixed column 10 and is provided with an external thread. The product placing table 13 is located on the upper end face of the threaded column 12 and used for placing a product to be processed, and the product to be processed is upwards abutted against the bottom face of the second round hole 22 in the first round hole 21, and the product to be processed can be products such as a machine core pressing piece. The core pressing piece is a sheet part which is pressed against the thermal infrared imager core and can be square, round and the like.
The inside wall of first round hole 21 is provided with the internal thread with screw post 12 complex for screw post 12 can be in the first round hole 21 of screw in, and place the platform 13 with the product and send into between the bottom surface of first round hole 21 and second round hole 22.
When the product placement table 13 is located between the bottom surfaces of the first circular hole 21 and the second circular hole 22, in order to place a product to be processed on the product placement table 13, a notch 23 is opened at the end surface of the second circular hole 22 of the fixed pressing block 20 from one side of the fixed pressing block 20 toward the second circular hole 22 at the round edge of the second circular hole 22, so that the product can be placed on the product placement table 13 through the notch 23. After the product is placed on the product placing table 13, the threaded column 12 rotates upwards in cooperation with the inner threads arranged on the inner side wall of the first round hole 21, and the product placing table 13 is matched with the bottom surface of the second round hole 22 to abut against the product tightly. The notch 23 may be square to accommodate square press members or circular press members, and the shape of the notch is designed according to the shape of the product.
Preferably, the notch 23 is also communicated with the first round hole 21, and an opening is formed on one side end face of the fixed pressing block. Therefore, the product can be replaced quickly and the cutter can process the product conveniently.
In a preferred example, the product placement table 13 is provided with a product positioning groove for defining a position where a product is placed. The shape of the product limiting groove is matched with the shape of the bottom surface of a product to be processed. For example, the notch 23 is square, and the product-limiting groove may be configured as a square, and the square product-limiting groove includes a first side wall, a second side wall, a third side wall, and a bottom surface. The first and second side walls are parallel to each other, and an opening is formed at a side opposite to the third side wall, and the opening can be aligned with the square notch 23 by rotating the fixing post 10, so that the product can be placed on the product placing table 13 through the square notch 23. Preferably, the width of the square notch 23 is substantially the same as the width of the third side wall of the product limiting groove (i.e. the left and right sides of the square notch are substantially located on the same straight line with the first side wall and the second side wall respectively), so that the product can slide into the product limiting groove in a manner of being simultaneously abutted against the first side wall, the second side wall and the bottom surface until being abutted against the third side wall.
Preferably, the fixing post 10 further comprises a stopper 14. The limiting member 14 is an annular protrusion structure, and is disposed between the threaded post 12 and the base 11 for limiting the rotation depth of the threaded post 12, so as to prolong the service life of the fixing post 10.
Preferably, the diameter of the base 11 is larger than that of the threaded column 12, so as to achieve the effect of convenient rotation.
The working process of the utility model will be described with reference to specific application scenarios:
please refer to fig. 4. Fig. 4 is a schematic diagram of an application environment of a core press rapid modification device. The utility model discloses in the device is through three-jaw chuck 30 clamping on the lathe, and its concretely processing product is the core casting die.
The first step is as follows: the threaded post 12 of the fixing post 10 is screwed into the first circular hole 21 so that the product placement table 13 is placed between the bottom surfaces of the first and second circular holes 21 and 22. A certain gap is formed between the product placement table 13 and the bottom surface of the second circular hole 22, and the gap is used for placing the core press piece.
The second step is that: the fixing post 10 is rotated by the base 11 so that the opening of the product restricting groove on the product placing table 13 is aligned with the notch 23.
The third step: put into the product spacing groove with the core casting die from the opening part in product spacing groove, the core casting die can't remove to the position except that the product spacing groove this moment. For example, when the notch 23 and the product limiting groove are square, the core pressing member slides into the product limiting groove in a manner of being simultaneously abutted against the first side wall, the second side wall and the bottom surface until being abutted against the third side wall.
The fourth step: the fixing column 10 is continuously rotated by the base 11, so that the product placing table 13 is rotated and moved toward the second circular hole 22. When the upper end of core casting die and the lower bottom surface butt of second round hole 22, and the opening direction of product spacing groove and the opening direction skew of notch 23 this moment, so far, core casting die is fixed completely, can't remove.
The fifth step: with fixed core casting die the utility model discloses a base 11 of core casting die quick modification device passes through three-jaw chuck 30 clamping on the lathe, selects corresponding cutter to process the core casting die according to finished product size required precision.
When the machined product needs to be replaced, the fixed pressing block 20 is rotated to enable the product placing table 13 to be in the same direction with the opening of the product release butt state and the opening of the product limiting groove and the opening of the notch 23, and at the moment, the machine core pressing piece can be taken out from the opening.
And (3) putting the replacement product into the opening, rotating the fixed pressing block 20 until the surface of the product placing table 13 is abutted against the fixed pressing block 20 and the opening direction of the product limiting groove is inconsistent with the opening direction of the notch 23. Therefore, the device of the utility model is not detached from the machine tool to replace the processed product.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
