Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0027] Example 1:
[0028] like Figure 1-7 As shown, this utility model provides a novel hole-machining fixture, comprising: a square column 1, with a clamping part 2 installed at one end and a central groove 3 at the other end. In use, a three-jaw chuck is used to clamp the product on the clamping part 2, and a center point is used to press against the center groove 3 to fix the clamping part 2. The three-jaw chuck and the center point are aligned. Two products 4 are mounted on the clamping part 2, each product 4 having an end face hole 16 and a side face hole 15. Two mounting grooves 5 are provided on the square column 2 to fit the products 4. The diameter of the mounting grooves 5 is slightly larger than the outer diameter of the products 4, allowing the products 4 to fit perfectly into the mounting grooves 5. To better fix the products 4 in the mounting grooves 5, a fixing mechanism is provided on the square column 5. The fixing mechanism includes an arc-shaped pressure block 6 slidably mounted on the side of the mounting groove 5. A square groove 8 is provided on the square column 1, and a block 9 is slidably mounted in the square groove 8. A screw 7 is threaded through the block 9 and screwed into the square groove 8. The square block 9 has a conical block 12 integrally installed on both sides. The conical block 12 contacts the pressure block 6. In use, the blank of product 4 is placed into the mounting groove 5, and then the screw 7 is rotated to move the screw 7 into the depth of the square groove 8, thereby causing the conical block 12 to squeeze the pressure block 6, so that the pressure block 6 presses the side of product 4 and fixes product 4 in the groove. The three-jaw chuck is rotated so that the side of product 4 that needs to be machined for the side hole 15 faces upward. The side hole 15 can be machined using a drilling machine. After the side hole 15 is machined, there is no need to remove product 4. Just rotate the three-jaw chuck 90 degrees so that the side of product end hole 16 faces upward, and then the end hole 16 can be machined using a drilling machine. This fixture only requires clamping product 4 once, and with simple adjustments, it can easily complete two different machining processes for the end face and side of two products 4, which can greatly improve the machining efficiency and avoid quality problems such as reduced accuracy and increased product indentation caused by repeated clamping.
[0029] By setting up a square column 1, a clamping part 2, a central groove 3, and a mounting groove 5, and setting up a fixing mechanism including a pressure block 6, a screw 7, a square groove 8, a square block 9, and a conical block 12, two products 4 can be clamped at one time, and the end face and side face of the product 4 can be easily machined, which can help improve processing efficiency and product quality.
[0030] Example 2:
[0031] like Figure 4 and Figure 6As shown, an integrally formed conical column 10 is installed on one side of the pressure block 6. The conical column 10 is slidably connected to the square column 1. The side of the conical column 10 facing the conical block 12 is inclined. When in use, the square block 9 moves along... Figure 6 Move in the indicated direction so that the conical block 12 on its side contacts and presses against the inclined surface of the conical column 10, causing the conical column 10 to move and push the pressure block 6 to move.
[0032] By installing a conical column 10 on one side of the pressure block 6, the pressure block 6 can be easily moved.
[0033] Example 3:
[0034] like Figure 5 As shown, a threaded hole 11 is provided on the block 9, and the screw 7 is connected to the threaded hole 11, thereby making the screw 7 threadedly connected to the block 9. A threaded groove is provided on one side of the square groove 8, and the end of the screw 7 is screwed into the threaded groove.
[0035] By setting threaded holes and threaded grooves, the installation and connection of screw 7 can be facilitated.
[0036] Example 4:
[0037] like Figure 3 As shown, a clearance groove 13 is provided on the square column 1. The clearance groove 13 is located at the machining position of the side hole 15 of the product 4. In use, it allows the product 4 to have as much contact area as possible with the mounting groove 4. Therefore, the machining position of the side hole 15 extends deep into the groove. Without the clearance groove 13, the side hole 15 could not be machined. Therefore, the provision of the clearance groove 13 can help improve the connection stability between the product 4 and the square column 1 and improve the machining quality.
[0038] By opening a clearance groove 13 on the square column 1, it is beneficial to improve the stability of product 4 during processing and improve the processing quality of the product.
[0039] Example 5:
[0040] like Figure 3 As shown, an air inlet / outlet hole 14 is provided on the square column 1. The air inlet / outlet hole 14 is located deep in the mounting groove 5. When using the product 4, when inserting the product 4 into the mounting groove 5 or removing the product 4 from the groove, the air in the mounting groove 5 can be discharged or entered through the air inlet / outlet hole 14, which can reduce the air pressure in the groove and make it easier to install and remove the product 4.
[0041] By opening air inlet and outlet holes 14 on the square column 1, it is possible to reduce the air pressure between the product 4 and the mounting groove 5, which facilitates the loading and unloading of the product 4.
[0042] Working principle: When in use, place the blank of product 4 into the mounting groove 5, then rotate the screw 7 to move the screw 7 deeper into the square groove 8, thereby causing the conical block 12 to press the pressure block 6, so that the pressure block 6 presses the side of product 4, fixing product 4 in the groove. Rotate the three-jaw chuck so that the side of product 4 that needs to be machined for the side hole 15 faces upward. The side hole 15 can be machined using a drilling machine. After the side hole 15 is machined, there is no need to remove product 4. Just rotate the three-jaw chuck 90 degrees so that the side of the end face hole 16 of the product faces upward, and then the end face hole 16 can be machined using a drilling machine. This fixture only requires clamping product 4 once, and with simple adjustments, it can easily complete two different machining processes for the end face and side face of two products 4, which can greatly improve the machining efficiency and avoid quality problems such as reduced accuracy and increased product indentation caused by repeated clamping.
