This device includes a support frame comprising a third plate, a second plate, and a first plate. The third plate is fixedly connected to one side of the second plate, and the first plate is fixedly connected to the other side of the second plate. The second plate has multiple threaded holes and multiple paired clamping shafts. Two support shafts are located at the end of the first plate furthest from the second plate. The multiple clamping shafts are rotatably connected to the two support shafts respectively. The ends of the two symmetrically positioned clamping shafts form a contact point when clamping the aluminum alloy sheet. Multiple drive mechanisms are used in conjunction with the paired clamping shafts. Each clamping shaft has a rotatably connected linkage shaft on one side, which is connected to the drive mechanism. The drive mechanism includes a cylinder, a traction shaft, and a moving shaft.
[0004] However, in the existing technology, when clamping aluminum alloy discs for drilling and tapping, uneven clamping force on the aluminum alloy discs can easily lead to angular displacement and detachment. Summary of the Invention

Detailed Implementation
[0018] Please see Figures 1 to 4This utility model provides a positioning and clamping device for a precision lathe used for machining aluminum alloy sheets, including a cylinder 101 and a positioning and clamping mechanism. The positioning and clamping mechanism includes a positioning plate 102, a lower positioning arc plate 103, an upper positioning arc plate 104, a connecting rod 105, a guide seat 106, and a guide rod 107. The positioning plate 102 has an opening. The lower positioning arc plate 103 is fixedly connected to the positioning plate 102 and located on one side of the positioning plate 102. The cylinder 101 is fixedly connected to the positioning plate 102 and located on the side of the positioning plate 102. On one side, one end of the connecting rod 105 is fixedly connected to the output end of the cylinder 101 and is located at one end of the cylinder 101, and the other end of the connecting rod 105 is fixedly connected to the positioning upper arc plate 104. The directional seat 106 is fixedly connected to the positioning plate 102 and is located on one side of the positioning plate 102. The connecting rod 105 passes through the directional seat 106. There are multiple sets of directional rods 107. One end of each set of directional rods 107 passes through the directional seat 106 and is fixedly connected to the positioning upper arc plate 104.
[0019] In this embodiment, the cylinder 101 and the lower positioning arc plate 103 are fixed to one side of the positioning plate 102, and the upper positioning arc plate 104 and the cylinder 101 are connected by the connecting rod 105. The cylinder 101 controls the position of the upper positioning arc plate 104. In use, the aluminum alloy disc is placed on the upper end of the lower positioning arc plate 103. At the same time, the cylinder 101 is driven to extend, and the connecting rod 105 drives the upper positioning arc plate 104 to move downward. Thus, the lower positioning arc plate 103 and the upper positioning arc plate 104 clamp the aluminum alloy disc. During the lifting and lowering movement, the upper positioning arc plate 104 is positioned and guided by the guide seat 106 and the guide rod 107 to ensure that the upper positioning arc plate 104 remains stable during the lifting and lowering movement and avoids displacement, thereby achieving the clamping and fixing of the aluminum alloy disc.
[0020] Furthermore, the positioning and clamping mechanism also includes anti-slip arc plates 108. There are two sets of anti-slip arc plates 108. Each set of anti-slip arc plates 108 is fixedly connected to the corresponding lower positioning arc plate 103 and the upper positioning arc plate 104, and is respectively embedded in the inner side of the corresponding lower positioning arc plate 103 and the upper positioning arc plate 104.
[0021] In this embodiment, by adding the anti-slip arc plate 108, the friction between the lower positioning arc plate 103 and the upper positioning arc plate 104 when clamping the aluminum alloy disc can be effectively increased, thereby improving the stability of the aluminum alloy disc during processing.
[0022] Furthermore, the positioning and clamping mechanism also includes positioning blocks and electromagnetic units. There are multiple sets of electromagnetic units, each set of electromagnetic units is fixedly connected to the positioning plate 102 and is embedded inside the positioning plate 102. There are multiple sets of positioning blocks, one end of each set of positioning blocks is embedded inside the positioning plate 102, and each set of positioning blocks is adapted to the corresponding electromagnetic unit.
[0023] In this embodiment, the electromagnetic unit is embedded inside the positioning plate 102. After the aluminum alloy disc is clamped and fixed by the lower positioning arc plate 103 and the upper positioning arc plate 104, the positioning block is then embedded and installed on one side of the corresponding electromagnetic unit. Each group of electromagnetic units is energized, and each group of positioning blocks is magnetically locked by electromagnetic force. When one end of the positioning block is locked, the other end positions and clamps the aluminum alloy disc.
[0024] Furthermore, each set of electromagnetic units includes an insulating outer cylinder 109, an energized coil 110, and an electromagnetic column 111. The insulating outer cylinder 109 is fixedly connected to the positioning plate 102 and embedded inside the positioning plate 102. The electromagnetic column 111 is fixedly connected to the insulating outer cylinder 109 and embedded inside the insulating outer cylinder 109. The energized coil 110 is embedded inside the insulating outer cylinder 109 and is sleeved on the outer wall of the electromagnetic column 111.
[0025] In this embodiment, the insulating outer cylinder 109 is embedded inside the positioning plate 102, and the insulating outer cylinder 109 is used to install and fix the energized coil 110 and the electromagnetic column 111. The electromagnetic column 111 and the energized coil 110 are respectively embedded inside the insulating outer cylinder 109. In use, the energized coil 110 is energized, so that the electromagnetic column 111 has electromagnetic force. The positioning block is magnetically fixed by the electromagnetic force, thereby realizing the positioning and clamping of the aluminum alloy disc. At the same time, when the electromagnetic unit is installed, the end face of the electromagnetic column 111 is lower than the end face of the positioning plate 102, which facilitates the placement of the positioning block.
[0026] Furthermore, each set of positioning blocks includes a positioning post 112, a clamping block 113, and an anti-slip pad 114. The clamping block 113 is fixedly connected to the positioning post 112 and is located at one end of the positioning post 112, and the other end of the positioning post 112 is adapted to the electromagnetic unit. The anti-slip pad 114 is fixedly connected to the clamping block 113 and is located on one side of the clamping block 113.
[0027] In this embodiment, the positioning post 112 is embedded inside the positioning plate 102 and is magnetically coupled with its electromagnetic unit. After the positioning post 112 is magnetically fixed, the clamping block 113 clamps and positions the aluminum alloy disc. At the same time, the anti-slip pad 114 provides anti-slip function while avoiding hard contact between the clamping block 113 and the aluminum alloy disc, thus ensuring the appearance of the aluminum alloy disc.
[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
