[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses a positioning device for a non-standard machine tool, comprising a mounting plate 1. Two first positioning components are symmetrically arranged at the top center of the mounting plate 1, and the first positioning components are used to position the bottom of the workpiece. An L-shaped support frame 6 is fixedly connected to the bottom of the mounting plate 1 near the rear side. An electric push rod 7 is fixedly installed on the top of the support frame 6. The bottom of the piston rod of the electric push rod 7 passes through the interior of the support frame 6 and is provided with a second positioning assembly. The second positioning assembly includes a fixed frame 9 fixedly connected to the bottom of the piston rod of the electric push rod 7, a pressure plate 8 fixedly connected to the bottom of the fixed frame 9, two second fixed plates 12 symmetrically fixedly connected to the top of the pressure plate 8, two second lead screws 11 inserted into the corresponding second fixed plates 12, two guide rods 13 slidably connected to the corresponding second fixed plates 12, two second clamping plates 14 fixedly connected to the ends of the guide rods 13 away from each other, and a dual-axis motor 10 fixedly connected to the inside of the fixed frame 9. The two second clamping plates 14 are threadedly connected to the corresponding second lead screws 11. The threads of the two second lead screws 11 are arranged in opposite directions, and the ends of the two second lead screws 11 that are close to each other pass through the fixed frame 9 and are fixedly connected to the output shaft of the dual-axis motor 10.
[0023] Specifically, after the workpiece is placed on top of the mounting plate 1, the electric push rod 7 can be controlled to move and drive the fixing frame 9 downward. The downward movement of the fixing frame 9 causes the pressure plate 8 to press against the top of the workpiece, which can improve the stability of the workpiece positioning. At the same time, the dual-axis motor 10 is controlled to drive the second lead screws 11 at both ends to rotate. Under the action of the rotation of the second lead screws 11, the second clamping plate 14 can move towards each other and fit against the outside of the workpiece, thereby further positioning the top of the workpiece, improving the stability of the workpiece positioning, and helping to ensure the accuracy and stability of the processing process.
[0024] Reference Figure 1 , Figure 2 and Figure 3The first positioning assembly includes a first fixed plate 2, a first lead screw 3, and a first clamping plate 4. The first fixed plate 2 is fixedly connected to the mounting plate 1, and the first lead screw 3 is threadedly connected to the first fixed plate 2. The first clamping plate 4 is slidably mounted on the top of the mounting plate 1 and forms a rotatable connection with the end of the first lead screw 3. The first clamping plate 4 adopts an L-shaped structure to enhance the clamping effect. The first positioning assembly also includes a knob 5, which is fixed to the end of the first lead screw 3 away from the first clamping plate 4. The position of the first clamping plate 4 can be easily adjusted by rotating the knob 5. Specifically, rotating the knob 5 drives the first lead screw 3 to rotate, and the rotation of the first lead screw 3 realizes the movement operation of the first clamping plate 4. The first clamping plate 4 moves to contact the outer side of the workpiece, which can better clamp and position the bottom of the workpiece, and the operation is simple.
[0025] Reference Figure 1 , Figure 2 and Figure 3 Rubber pads 16 are fixed to the bottom of the pressure plate 8 and the adjacent ends of the two second clamping plates 14 to improve the anti-slip properties during clamping.
[0026] Multiple fixing slots 15 are symmetrically and evenly opened around the four sides of the mounting plate 1 to facilitate connection and fixation with the mounting surface of the machine tool.
[0027] Both the electric actuator 7 and the dual-axis motor 10 are electrically connected to external control equipment to achieve control and automated operation.
[0028] Working principle: The workpiece is placed on the mounting plate 1. By rotating the knob 5, the first lead screw 3 can be rotated. The rotation of the first lead screw 3 can realize the movement operation of the first clamping plate 4. The first clamping plate 4 moves and contacts the outside of the workpiece, which can better clamp and position the bottom of the workpiece.
[0029] Then, the electric push rod 7 is controlled to move and drive the fixed frame 9 downward. The downward movement of the fixed frame 9 causes the pressure plate 8 to press against the top of the workpiece, which can improve the stability of the workpiece positioning. At the same time, the dual-axis motor 10 is controlled to drive the second lead screws 11 at both ends to rotate. Under the action of the rotation of the second lead screws 11, the second clamping plate 14 can move towards each other and fit against the outside of the workpiece, thereby further positioning the top of the workpiece, improving the stability of the workpiece positioning, and helping to ensure the accuracy and stability of the processing process.
[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
