Description

Technical Field

[0001] This utility model belongs to the field of positioning and machining technology, and in particular to a positioning and clamping device for a five-axis CNC machine tool. Background Technology

[0002] Five-axis CNC machine tools are high-tech, high-precision machine tools specifically designed for machining complex curved surfaces. Before machining, CNC machine tools use positioning and clamping devices for positioning and clamping. Traditional fixing devices cannot adjust the tilt angle of the fixing blocks and cannot meet the needs of irregular products, especially those with inclined surfaces.

[0003] A search revealed a Chinese patent document (authorization announcement number CN219005356U) entitled "A Five-Axis CNC Machine Tool Machining Positioning and Clamping Device," comprising a fixed plate, a support base fixedly mounted at the top center of the fixed plate, a top box fixedly mounted at the top center of the support base, brackets fixedly mounted on the tops of both sides of the support base, a machining table fixedly mounted on the top of the brackets, a sliding block slidably mounted inside the top box, connecting rods fixedly mounted at both ends of the sliding block, the top of the connecting rods penetrating the machining table and fixedly connecting to a clamping plate, a positioning block fixedly mounted on one side of the top of the machining table, and a sliding groove formed in the middle of both the clamping plate and the positioning block, with an auxiliary plate slidably mounted inside the sliding groove. This invention uses the sliding block to move the clamping plate, thereby fixing the workpiece with the clamping plate and positioning block, facilitating subsequent positioning. The distance the clamping plate moves can be adjusted according to the size of the workpiece for fixing, making it simple and convenient. While the fixing device can provide stable fixation, it cannot adjust the tilt angle of the fixing block, making it unsuitable for irregular products, especially those with inclined surfaces. Utility Model Content

[0004] The purpose of this invention is to provide a positioning and clamping device for a five-axis CNC machine tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and clamping device for a five-axis CNC machine tool, comprising:

[0006] The assembly and mounting plate has four assembly and mounting notches at its top.

[0007] Four linear motors are respectively mounted on the transverse inner walls of the four mounting slots of the mounting plate. The top of the moving part of the linear motor is mounted on a mounting block. The top of the mounting block is mounted on multiple vertical electric push rods. The moving parts of the multiple vertical electric push rods are connected to an auxiliary plate.

[0008] The forward and reverse motors are mounted on the top of the auxiliary plate. The output shafts of the forward and reverse motors are connected to the auxiliary block via a coupling. A transverse electric push rod is embedded in the side of the auxiliary block. An adjustment plate is connected to the side of the moving part of the transverse electric push rod. Multiple pressure sensors are connected to the side of the adjustment plate. The multiple pressure sensors are connected to a positioning clamping plate for positioning and clamping the product to be processed.

[0009] As a preferred embodiment, the top of the mounting plate is provided with multiple countersunk holes, and countersunk bolts for detachable connection with a five-axis CNC machine tool are provided in the countersunk holes.

[0010] As a preferred embodiment, the top of the mounting plate is provided with a cross notch, and a matching cross plate is provided in the cross notch.

[0011] As a preferred embodiment, an auxiliary electric push rod is embedded in the inner wall of the cross notch of the mounting plate, and the moving part of the auxiliary electric push rod is connected and fixed to the cross plate.

[0012] As a preferred embodiment, the side of the cross plate is provided with scale lines.

[0013] As a preferred embodiment, both sides of the positioning clamping plate are rotatably connected to clamping sub-plates via damping shafts, and the clamping sub-plates are connected and fixed to the positioning clamping plate via latches.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] This five-axis CNC machine tool positioning and clamping device uses four linear motors that move to different degrees to accommodate products of different sizes. The forward and reverse motors drive the output shaft to rotate, which in turn drives the auxiliary block to rotate, changing the tilt angle of the positioning and clamping plate to accommodate irregular products.

[0016] This five-axis CNC machine tool positioning and clamping device uses a vertical electric push rod in conjunction with an auxiliary electric push rod to change the height of the positioning clamping plate and the cross plate to meet different fixing needs. The extension and retraction of the horizontal electric push rod changes the distance between the positioning clamping plate and the forward and reverse motors, thereby adapting to different fixing needs. When the clamping sub-plate rotates to be parallel with the positioning clamping plate, it is fixed by a locking buckle, thereby increasing the fixing area.

[0017] This five-axis CNC machine tool positioning and clamping device is adjustable and can accommodate the fixing of irregular products. Attached Figure Description

The moving parts of the multiple vertical electric push rods 4 are connected to the auxiliary plate 5.

[0032] A forward and reverse motor 6 is mounted on the top of an auxiliary plate 5. The output shaft of the forward and reverse motor 6 is connected to an auxiliary block 7 via a coupling. A transverse electric push rod 8 is embedded in the side of the auxiliary block 7. The extension and retraction of the transverse electric push rod 8 changes the distance between the positioning clamping plate 11 and the forward and reverse motor 6, thereby adapting to different fixing needs. An adjusting plate 9 is connected to the side of the moving part of the transverse electric push rod 8. Multiple pressure sensors 10 are connected to the side of the adjusting plate 9. The multiple pressure sensors 10 are connected together to the positioning clamping plate 11 used for positioning and clamping the product to be processed. 1. Both sides of the positioning clamping plate 11 are rotatably connected to clamping sub-plates 15 via damping shafts. The clamping sub-plates 15 are connected and fixed to the positioning clamping plate 11 via latches. When the clamping sub-plates 15 rotate to be parallel to the positioning clamping plate 11, they are fixed by latches, increasing the fixed area. The product to be positioned and clamped is placed on the assembly mounting plate 1. The forward and reverse motors 6 are pre-adjusted to indirectly drive the positioning clamping plate 11 to rotate, changing the tilt angle of the positioning clamping plate 11. The four linear motors 2 are adjusted so that the positioning clamping plate 11 fixes the product.

[0033] The top of the mounting plate 1 has multiple countersunk holes, and countersunk bolts 12 for detachable connection with a five-axis CNC machine tool are installed in the countersunk holes.

The auxiliary electric push rod 14 changes the height of the cross plate 13 to meet different fixing needs, such as unloading after processing.

[0035] The linear motor 2, vertical electric actuator 4, forward and reverse motor 6, auxiliary electric actuator 8, pressure sensor 10, and auxiliary electric actuator 14 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
