[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments disclosed herein will be described in further detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] This application discloses a positioning fixture for glass processing in a single-arm oscillating grinding and polishing machine, such as... Figure 1 As shown, it includes multiple positioning devices mounted on the turntable of a single-arm oscillating grinding and polishing machine. Each positioning device includes a mounting component and a chuck 7. Each mounting component is connected to a chuck 7, and the chuck 7 is made of polytetrafluoroethylene.

[0026] The turntable of the single-arm oscillating grinding and polishing machine has multiple parallel T-slots, and the mounting components are installed in these T-slots. For a circular window glass, two mounting components are connected in the same T-slot, which is called the first T-slot, so that the window glass is located between the clamps 7 of the two mounting components. A second T-slot is defined on one side of the first T-slot, and a third T-slot is defined on the other side. A positioning device is installed in the second T-slot and a positioning device is installed in the third T-slot, and the clamps 7 connected to the positioning devices in the second and third T-slots are brought into contact with the window glass.

[0027] like Figure 3 As shown, the mounting components include a T-block 4, a rotating mechanism 5, a lead screw 2, a handwheel 1, a first bolt 3, and a fixing bolt 9.

[0028] The bottom of the T-block 4 is provided with a T-shaped protrusion, which mates with the T-slot on the turntable of the single-arm axis oscillating grinding and polishing machine. The first bolt 3 passes through the T-shaped protrusion and is threadedly connected to it. Tightening the first bolt 3 causes the bottom end of the first bolt 3 to abut against the bottom of the T-slot, thus fixing the T-shaped protrusion to the turntable of the single-arm axis oscillating grinding and polishing machine.

[0029] A mounting groove is formed on the T-shaped block 4, and the bottom end of the rotating mechanism 5 is provided with a cylindrical portion which is located in the mounting groove and can rotate along the axis of the mounting groove; a ring groove is formed on the outer circumferential surface of the cylindrical portion, and the fixing bolt 9 is threadedly connected to the rotating mechanism 5, and when the fixing bolt 9 is tightened, one end of the fixing bolt 9 extends into the mounting groove, and the end of the fixing bolt 9 is clamped into the ring groove. Thus, the T-shaped block 4 and the rotating mechanism 5 are fixed, and the rotating mechanism 5 and the T-shaped block 4 no longer rotate relative to each other; when the fixing bolt 9 is loosened, the rotating mechanism 5 and the T-shaped block 4 can rotate relative to each other.

[0030] A threaded hole is formed at the position of the axis of the rotating mechanism 5, and the lead screw 2 passes through the hole, and the lead screw 2 can move along the axis of the threaded hole relative to the rotating mechanism 5, and the movement of the lead screw 2 drives the movement of the chuck 7.

[0031] The hand wheel 1 is connected to one end of the lead screw 2, and the chuck 7 is connected to the other end of the lead screw 2. Specifically, one end of the lead screw 2 is provided with a ball structure, and one end of the chuck 7 is provided with a groove matched with the ball structure, so that the chuck 7 and the lead screw 2 are ball-hinged, and the other end of the chuck 7 is a V-shaped opening structure, and the V-shaped opening is preferably 90°. The other end of the lead screw 2 is a square joint, and the hand wheel 1 is provided with a square interface, and the square joint is matched with the square interface, so that the hand wheel 1 is installed on the end of the lead screw 2, and the rotation of the hand wheel 1 drives the rotation of the lead screw 2.

[0032] The lock nut 6 is threadedly connected to the outside of the lead screw 2. When the lead screw 2 drives the chuck 7 to move to the position, the lock nut 6 is tightened until the end of the lock nut 6 abuts against the end of the rotating mechanism 5, and at this time, the lead screw 2 is locked and cannot continue to rotate.

[0033] The implementation principle of the patent is:

[0034] The T-shaped groove on the rotating disc of the single-arm shaft swing grinding and polishing machine tool is used to quickly clamp four mounting assemblies in the T-shaped groove, and the positions of the four mounting assemblies are sequentially connected to form a rectangle or a square. The direction of the rotating mechanism 5 is adjusted to align the chuck 7 with the window glass, the hand wheel is rotated to drive the lead screw 2 and the chuck 7 to adjust forward and backward, the chuck 7 is held at the beginning to avoid rotating with the lead screw 2, and after the chuck 7 contacts the window glass, the hand is released, the lead screw 2 is continuously rotated to drive the chuck to adjust the position of the window glass, and when the adjustment of the position of the window glass is completed, the lead screw is locked by the lock nut to complete the adjustment.

[0035] Put the T-shaped block 4 into the single-axis swing grinding machine turntable T-shaped slot, according to the size and shape of the window glass, use the bolt 3 to fix the T-shaped block 4 in the distance of 10cm from the part, rotate the rotating mechanism 5 to make the chuck 7 align with the window glass, rotate the hand wheel 1 to adjust the lead screw 2, the lead screw 2 drives the chuck 7 to adjust the window glass, when the position degree of the window glass is adjusted, lock the lock nut 6 to lock the lead screw to achieve the positioning and fastening of the window glass.

[0036] Example 2

[0037] As shown in Figure 2 , Figure 4 and Figure 5 , the difference from example 1 is that the mounting assembly also includes a moving plate 8. And the moving plate 8 is connected with the rotating mechanism 5 through a square slot, so that the moving plate 8 can only move linearly along its own axis relative to the rotating mechanism 5.

[0038] Rotate the lead screw 2, the lead screw 2 drives the chuck 7 to move, and then the chuck 7 drives the moving plate 8 to move linearly, the lead screw 2 drives the chuck 7 to clamp the window glass. The position of the chuck is stable during this process, and it does not need to be held by hand before the chuck contacts the window glass.
