Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grinding fixture technology, specifically, it relates to a manual grinding and repair fixture for laptop computer casing workpieces. Background Technology
[0002] In the production process of laptop casings, the sides of the finished casings need to be sanded and repaired. However, because laptop casings are not very large, machine sanding would be time-consuming and the loading and unloading process would be overly complex, resulting in low overall efficiency. Therefore, manual sanding is still the most common method used in the industry.
[0003] However, manual polishing still presents challenges in improving work efficiency, especially in securing laptop casings. Laptop casings typically have curved edges, and since all four sides need to be inspected and polished, the traditional polishing process involves placing the casing flat on the workbench. However, this is clearly inconvenient for workers, preventing them from operating in a proper sitting position and severely impacting work efficiency. Utility Model Content
[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a manual grinding and repair fixture for laptop shell workpieces, so as to solve the problem that the traditional grinding method in the existing technology causes workers to be overly tired and unable to grind in a more relaxed and convenient posture, thereby improving work efficiency.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0006] A manual grinding and repair fixture for laptop casing parts, including a base set on a work platform;
[0007] A column is provided on the base, and a rotatable and fixed connecting arm is provided on the top of the column. The connecting arm can rotate in a vertical plane, and a turntable is provided on the connecting arm. The turntable can rotate freely in a plane perpendicular to the connecting arm, and a grinding plate parallel to the rotation surface of the turntable is fixedly connected to the turntable.
[0008] The back of the grinding plate is fixedly connected to the turntable. The front of the grinding plate is rectangular and matches the size of the laptop shell workpiece to be ground. The front of the grinding plate has rounded corners on all four sides that transition to the back.
[0009] Furthermore, the position of the base on the working platform is adjustable.
[0010] Furthermore, a number of positioning holes are provided on the working platform, and a fixing groove is provided on the base. The shape and size of the fixing groove correspond to the positioning holes. The base is installed by a positioning component that passes through the fixing groove and is inserted into the positioning hole.
[0011] Furthermore, the positioning hole is square, and the positioning member includes a columnar portion capable of inclining the positioning hole. A positioning plate is provided on the top of the columnar portion, and the area of the positioning plate is larger than the area of the positioning hole.
[0012] Furthermore, four first fixing holes that can form a square are provided on the turntable, and four second fixing holes of corresponding position and size are also provided on the back of the grinding plate. The first fixing holes and the second fixing holes are fixed together by bolts.
[0013] Furthermore, the connecting arm is connected to the column by a tightening bolt.
[0014] Furthermore, the grinding plate can be additionally fixed to the side of the work platform by a U-shaped plate, and the U-shaped groove formed on the U-shaped plate can be locked onto the side of the work platform.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This utility model designs a manual grinding and repair fixture for laptop casings. By using this fixture, workers can grind and repair laptop casings in a free, comfortable and convenient posture and angle.

Detailed Implementation
[0024] The present invention will be further described below with reference to specific embodiments.
[0025] like Figures 1-4 As shown in Embodiment 1, the manual grinding and repair fixture for laptop casing workpieces described in this utility model includes a flat work platform 1, which sits on a machine base 11. Several positioning holes 3 are provided on the surface of the work platform 1, allowing the operator to easily and quickly lift and lower the work platform 1 by inserting their fingers into the positioning holes 3. At the same time, there is a gap between the work platform 1 and the machine base 11.
[0026] The fixture also includes a base 2 set on the work platform 1. Specifically, the base 2 is rectangular in shape and has two fixing grooves 4 on the left and right sides. The width of the fixing grooves 4 is the same as that of the positioning holes 3. Thus, the base 2 can be fixedly installed on different positions on the work platform 1 by inserting the positioning piece 5 through the fixing grooves 4 into the positioning holes 3, thereby making it convenient for the staff to adjust the position of the base 2 according to their own position and grinding needs.
[0027] In this embodiment, the positioning hole 3 is square, and the positioning component 5 includes a columnar part 51 that can be cut into the positioning hole 3. A positioning plate 52 is provided on the top of the columnar part 51. The area of the positioning plate 52 is larger than the area of the positioning hole 3. This allows the operator to easily insert the columnar part 51 through the fixing groove 4 into the positioning hole 3. After insertion, the positioning plate 52 will fall on the base 2. At the same time, the base 2 is fixed by the two fixing grooves on the left and right, and will not easily shake or shift.
[0028] A column 6 is provided on the base 2, and a connecting hole is opened at the top of the column 6. A rotatable and fixed connecting arm 8 is connected to the connecting hole by a tightening bolt 7. The connecting arm 8 can rotate in a vertical plane. Subsequently, a turntable 9 is provided at the other end of the connecting arm 8. The turntable 9 can rotate freely in a plane perpendicular to the connecting arm 8. In this embodiment, the specific rotation connection method is not limited, and there are many ways to achieve this in the prior art. A grinding plate 10 parallel to the rotation surface of the turntable 9 is also fixedly connected to the turntable 9.
[0029] The back of the polishing plate 10 is fixedly connected to the turntable 9, while the front is rectangular. The size and dimensions of the rectangle are matched with the dimensions of the laptop shell workpiece to be polished. In addition, rounded corners 12 that transition to the back are formed on the four sides of the front of the polishing plate 10.
[0030] In the above technical solution, the grinding plate 10 with a rectangular front allows the worker to hang the side of the laptop shell workpiece that needs to be ground on the side of the grinding plate 10. The rounded corner 12 can match the shape of the inwardly curved and concave side of the laptop shell workpiece, improving the stability after hanging and preventing scratches and other effects on the inside of the laptop shell workpiece.
[0031] With the above design, when workers need to polish and repair laptop casings, they can first fix the base 2 to a suitable position using the positioning piece 5, then adjust the angle of the connecting arm 8 and secure it with the locking bolt 7. Next, the laptop casing to be polished can be hung on the polishing plate 10, and the turntable 9 can be rotated to adjust the side of the laptop casing to a suitable angle. Finally, the polishing and repair can be performed. The overall operation is simple and quick, and allows workers to operate in a very convenient and comfortable posture, effectively improving work efficiency.
[0032] In addition, in this embodiment, four first fixing holes 13 that can form a square are provided on the turntable 9, and four second fixing holes 14 with corresponding positions and sizes are also provided on the back of the grinding plate 10. The first fixing holes 13 and the second fixing holes 14 are fixed together by bolts. Thus, the operator can rotate the grinding plate 10 90° to install it according to the needs of operating comfort.
[0033] like Figures 5-6 As shown, in Embodiment 2, the grinding plate 10 can be additionally fixed to the side of the work platform 1 by a separate U-shaped plate 15, that is, at the gap between the work platform 1 and the machine base 11. The U-shaped groove 16 formed on the U-shaped plate 15 can be locked into the side of the work platform 1, thus providing another implementation scheme for the operator to choose to operate.
