DETAILED DESCRIPTION
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0023] This application provides a precision workpiece grinding machine, mainly to address the problem that existing technologies suffer from fixed distances between the fixture and the grinding head, or limited range of motion of the grinding head, making them inadequate when dealing with steel pipes of different diameters or lengths. Therefore, when processing workpieces of different specifications, it is often necessary to change different equipment or adjust machine settings, which not only increases production costs but also significantly reduces production efficiency. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:
[0024] A precision workpiece grinding machine, comprising:
[0025] Base 1, with a U-shaped plate 2 fixed to the top of base 1;
[0026] Grinding plate 3 and mounting plate 4, the mounting plate 4 is set inside the upper side of the U-shaped plate 2, and the grinding plate 3 is fixed to the bottom of the mounting plate 4;
[0027] The lifting mechanism 5 is located on the upper side inside the U-shaped plate 2. The lifting mechanism 5 is used to adjust the height of the mounting plate 4.
[0028] The rotating fixture 7 and the steel pipe to be processed 8 are arranged inside the bottom side of the U-shaped plate 2. The rotating fixture 7 is used to drive the steel pipe to be processed 8 to rotate. The rotating fixture 7 includes rotating rods 701 rotating on the bottom of both sides of the U-shaped plate 2. A drive motor 702 is installed on the bottom of one side of the U-shaped plate 2. The output shaft of the drive motor 702 is connected to the rotating rod 701. A rectangular frame 703 is fixed at one end of the two rotating rods 701 inside the U-shaped plate 2. An adjusting rod 704 is threaded to the other side of the rectangular frame 703. A connecting block 705 is fixed on the side of the adjusting rod 704 away from the rectangular frame 703. The connecting block 705 is embedded inside the steel pipe 8 to be processed.
[0029] Workflow Description:
[0030] The first step is to install the steel pipe to be processed 8: Place the steel pipe to be processed on the rotating fixture 7, and adjust the adjusting rod 704 and the connecting block 705 on the rotating rod 701 to make the connecting block 705 tightly embedded in the steel pipe, so that the steel pipe will not slip during the processing.
[0031] The second step is to adjust the position of the grinding plate 3: Based on the diameter and length of the steel pipe, the height of the mounting plate 4 is adjusted using the lifting mechanism 5, thereby changing the distance between the grinding plate 3 and the steel pipe to achieve the best grinding effect.
[0032] The third step is to start the drive motor 702: turn on the drive motor 702 at the bottom of the U-shaped plate 2, and drive the rectangular frame 703 and the connecting block 705 to rotate through the rotating rod 701, thereby causing the steel pipe to rotate. When the steel pipe rotates, the grinding plate 3 installed at the bottom of the mounting plate 4 begins to grind the surface of the steel pipe.
[0033] Step 4: Stop the equipment after grinding: After grinding is completed, turn off the drive motor 702 to stop rotation.
[0034] Step 5: Remove the finished product: Loosen the locking nut on the adjusting rod 704, pull the connecting block 705 out of the steel pipe, and then remove the processed steel pipe.
[0035] This precision workpiece grinding machine adopts a unique rotating tooling system 7, including components such as a rotating rod 701, a rectangular frame 703, an adjusting rod 704, and a connecting block 705. It can firmly fix steel pipes of various lengths and specifications and drive them to rotate. At the same time, by introducing a lifting mechanism 5, the grinding plate 3 can move up and down as needed to adapt to steel pipes of different specifications. By precisely adjusting the distance between the grinding plate 3 and the steel pipe, higher processing accuracy can be achieved, thereby improving processing quality.
[0036] like Figure 4 As shown, in some embodiments, the connecting block 705 is conical, and its surface is fitted with an anti-slip sleeve. More specifically, the conical design allows the connecting block 705 to form a tight fit with the inside of the steel pipe. When the connecting block 705 is inserted into the steel pipe, due to its conical shape, it forms a gradually increasing contact area with the inner wall of the steel pipe, thereby generating greater friction and effectively preventing the steel pipe from sliding during grinding. When the conical connecting block 705 is inserted into the steel pipe, it can naturally find the center position of the steel pipe, so that the steel pipe can maintain accurate concentricity on the rotating fixture 7. During the grinding process, there will be relative movement between the connecting block 705 and the inner wall of the steel pipe, which can easily cause wear. The anti-slip sleeve has good wear resistance and can withstand long-term friction without being easily damaged, ensuring the reliability of the connection between the connecting block 705 and the steel pipe.
[0037] like Figure 1As shown, in some embodiments, the lifting mechanism 5 includes a mounting rod 501 rotatably connected between the inner walls of the U-shaped plate 2. Both sides of the mounting rod 501 are constructed with threads in opposite directions and are symmetrically connected to mounting blocks 502. The mounting blocks 502 are slidably connected to the inner top wall of the U-shaped plate 2. A hinge plate 503 is hinged to the bottom of the mounting blocks 502. A lifting plate 504 is slidably disposed inside the U-shaped plate 2 below the mounting rod 501. The end of the hinge plate 503 away from the mounting blocks 502 is hinged to the lifting plate 504. A connector 6 is provided at the bottom of the lifting plate 504 for connecting the mounting plate 4. More specifically, when the operator rotates the mounting rod 501, because the threads on both sides of the mounting rod 501 are in opposite directions, the mounting blocks 502 will move in opposite directions. The movement of the slider causes the hinge plate 503 to change angle, and through the hinge relationship, the lifting plate 504 rises or falls, thereby changing the height of the mounting plate 4.
[0038] like Figure 4 As shown, in some embodiments, the connector 6 includes L-shaped plates 601 symmetrically fixed on both sides of the bottom of the lifting plate 504. The bottom of the L-shaped plate 601 has a slot 6011. The two sides of the mounting plate 4 are embedded in the slot 6011. The middle of the lifting plate 504 is threaded with a locking bolt 602. The top of the mounting plate 4 has a connecting groove. The locking bolt 602 and the connecting groove are matched in size and position. More specifically, when installing the mounting plate 4, the mounting plate 4 can be placed inside the slot 6011, and then the locking bolt 602 can be rotated so that its bottom end is embedded in the connecting groove. This can fix the mounting plate 4, thereby ensuring the stability of the grinding plate 3.
[0039] like Figure 1 As shown, in some embodiments, the bottom of the grinding plate 3 is constructed with an arc-shaped notch 301. More specifically, during the grinding process, the grinding plate 3 can match the natural shape of the workpiece surface through the arc-shaped notch 301, ensuring that the grinding force is evenly distributed throughout the contact area. Compared with the flat grinding plate 3, the grinding plate 3 with the arc-shaped notch 301 can provide a larger effective contact area when in contact with the workpiece. This helps to improve grinding efficiency, reduce vibration and jumping during the grinding process, and thus obtain a smoother grinding effect.
