When machining forgings on multiple sides, multiple disassemblies, re-alignments, and clampings are necessary, which is not only time-consuming and labor-intensive, but also prone to reduced positioning accuracy due to repeated clamping errors, affecting machining quality and resulting in low machining efficiency. Human factors often cause errors in alignment, clamping, and measurement, leading to scrapped parts, losses for the company, and delays in product cycles. To address the shortcomings of existing technologies, we propose a precision positioning fixture for forgings to solve the above problems. Utility Model Content

A forging body 3 is respectively mounted on the top of both fixture body 1 and fixture body 2. Fixture body 1 consists of a tooling base 11 and a tooling fixture 12. The two tooling bases are fixedly installed on the machine tool. The tooling fixture 12 is located on top of the tooling base 11 and consists of a first positioning block 121, a second positioning block 122, a first irregularly shaped pressure plate 123, a second irregularly shaped pressure plate 124, and a rhomboid positioning block. The forging body 3 is composed of a first positioning block 121, a second positioning block 122, a first irregular pressure plate 123, a second irregular pressure plate 124, and a prismatic positioning pin 125, which clamp and fix the forging body 3 in multiple directions. When performing multi-face processing operations on the forging body 3, it is necessary to clamp the forging body 3 with two sets of clamping bodies, so that the forging body 3 can be processed in multiple directions during the clamping process of the two sets of clamping bodies.

[0027] Reference Appendix Figure 1-4 The fixture body 2 consists of a tooling base 21 and a tooling fixture 22. The tooling fixture 22 is located on top of the tooling base 21. The tooling fixture 22 includes a fixed vise 221, a movable vise 222, a first positioning block 223, a second positioning block 224, and a prismatic positioning pin 225. The fixed vise 221, the movable vise 222, the first positioning block 223, the second positioning block 224, and the prismatic positioning pin 225 clamp and fix the forging body 3 in multiple directions. When clamping and fixing the forging body 3 through the fixture body 1, firstly, lift the forging body 3, raise it above the two sets of positioning blocks 2, and fit it onto the outer wall, so that both ends of the forging body 3 are respectively attached to the outer walls of the two sets of positioning blocks 2. Thus, the two sets of positioning blocks 2 can limit and fix the forging body 3 from the Z-axis direction. For details, please refer to the appendix. Figure 3Then, the two irregularly shaped pressure plates on both sides are pushed to fit and limit the two sets of irregularly shaped pressure plates on the top sides of the forging body 3. Finally, the fixed bolts are threaded inside the two sets of irregularly shaped pressure plates to limit their position. The two sets of irregularly shaped pressure plates can limit and fix the forging body 3 from the Y-axis direction. Finally, the rhomboid locating pin 125 is picked up and inserted into the forging body 3 and the first locating block 121, so that the position of the hole of the rhomboid locating pin 125 after insertion corresponds to the position of the hole of the first locating block 121. Then, the threaded bolt 1251 is threaded into the... The prismatic locating pin 125 and the first locating block 121 lock the position of the prismatic locating pin 125 after installation, thereby enabling the prismatic locating pin 125 to limit and fix the forging body 3 from the X-axis direction. The tooling fixture 12 can quickly position and clamp the forging body 3 from multiple directions, improving the stability of the forging body 3 after positioning. After machining the A side of the forging body 3, the forging body 3 is flipped over to facilitate the machining of the B side of the forging body 3. The A and B sides of the fixed forging body 3 can be machined separately, ensuring stability during the machining process.

[0028] Reference Appendix Figure 1-4 The first positioning block 121 and the second positioning block 122 are respectively fixedly installed on the top two sides of the tooling base 11. The two ends of the die forging body 3 are respectively attached to the outer walls of the first positioning block 121 and the second positioning block 122. The first irregular pressure plate 123 and the second irregular pressure plate 124 are respectively attached to the top two sides of the die forging body 3. The pressure plate base 1231 is fixedly installed on the top two sides of the tooling base 11. The bottom of the first irregular pressure plate 123 and the second irregular pressure plate 124 are respectively rotatably connected to the inside of the two sets of pressure plate base 1231. The inside of the first irregular pressure plate 123 and the second irregular pressure plate 124 is respectively provided with threaded holes 1232. After the two sets of irregular plates are attached to the top of the die forging body 3, the fixing bolts are threadedly connected to the inside of the two sets of irregular plates and the tooling base 11, so as to limit the position of the two sets of irregular plates and prevent them from detaching during the processing.

[0029] Reference Appendix Figure 1-4A prismatic locating pin 125 is inserted into the first locating block 121 and the forging body 3. A threaded bolt 1251 is provided on the top of the first locating block 121. The threaded bolt 1251 is threadedly connected to the first locating block 121 and the prismatic locating pin 125. The prismatic locating pin 125 is inserted into the first locating block 121 and the forging body 3. Since the first locating block 121 is in a fixed state, and a hole is provided inside one end of the forging body 3, it is convenient to pass the prismatic locating pin 125 through the hole to limit the connection between the first locating block 121 and the forging body 3. This can prevent the forging body 3 from easily moving in the X-axis direction, thereby ensuring the accuracy of the installation position of multiple sets of forging bodies 3 and fixture body 1, and improving the processing quality of multiple sets of forging bodies 3.

[0030] Example 2

[0031] Reference Appendix Figure 4-6 Fixed vise 221 and movable vise 222 are respectively set on the top two sides of tooling base 21. Fixed vise 221 is fixedly installed on the inner wall of one side of tooling base 21, and movable vise 222 is slidably connected to the top of tooling base 21. First positioning block 223 and second positioning block 224 are respectively fixedly installed on the inner wall of fixed vise 221. When it is necessary to process the C and D surfaces of the forging body 3, it is necessary to use fixture body 22 to position and fix the forging body 3, so that the C and D surfaces of the forging body 3 can face upwards, which facilitates the processing operation of the C and D surfaces of the forging body 3.

[0032] Reference Appendix Figure 4-6The two ends of the forged body 3 are respectively attached to the top and bottom of the first positioning block 223 and the second positioning block 224. The rhomboid positioning pin 225 is inserted into the first positioning block 223 and the interior of the forged body 3. The outer wall of the first positioning block 223 is provided with a threaded bolt 2251, which is threadedly connected to the interior of the first positioning block 223 and the rhomboid positioning pin 225. During the clamping and fixing of the forged body 3, the forged body 3 is first picked up and placed on one side of the two sets of positioning blocks 2. Then, the two ends of the forged body 3 after installation are respectively located at the top and bottom of the two sets of positioning blocks 2 and attached to the inner wall of the fixing vise 221. Then, by rotating the drive knob 2222, the drive knob 2222 drives the adjusting screw 2221 to be threadedly connected to the side wall of the tooling base 21, and pushes the movable vise 2. 22. Move closer to the fixed vise 221 and clamp the forging body 3 between the two sets of vises. This allows the forging body 3 to be limited and fixed from the X-axis direction using the two sets of vises. Finally, pick up the rhomboid locating pin 225 and insert it into the first locating block 223 and the forging body 3. Then, thread the threaded bolt 2251 to the first locating block 223 and the forging body 3. This allows the position of the rhomboid locating pin 225 to be fixed after installation. The rhomboid locating pin 225 allows the forging body 3 to be limited and fixed from the Y and Z axes. This allows for rapid positioning and clamping of multiple sets of forging bodies 3 from multiple directions, ensuring the accuracy of the installation position of multiple sets of forging bodies 3 and fixture body 1, and improving the processing quality of multiple sets of forging bodies 3.

[0033] Reference Appendix Figure 4-6 The inner side wall of the tooling base 21 is threaded with an adjusting screw 2221. One end of the adjusting screw 2221 is rotatably connected to the outer wall of the movable vise 222, and the other end of the adjusting screw 2221 is fixedly installed with a drive knob 2222.
