Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a linear motor mounting device and a direct-drive CNC machine tool. Background Technology

[0002] Linear motors can be directly integrated with motion actuators. Compared with traditional transmission methods such as lead screws, gears, and racks, they have advantages such as high speed, high precision, long lifespan, and no wear. With the development of high-precision technology, they are now being used more and more in fields such as semiconductors, machine tools, and industrial robots.

[0003] However, currently, when installing linear motors, it is often done manually by holding the linear motor and placing it in the designated position, and then using tools to install it in the designated position. Because linear motors are bulky, they are prone to instability when manually held, resulting in installation deviations, which is quite inconvenient. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 3 A linear motor mounting device, comprising:

[0026] Fixed frame 1; sliding groove 2, which is opened on the side of fixed frame 1, and lifting frame 3 is slidably connected in sliding groove 2.

[0027] The support and fixing components include a support plate 4 slidably connected to the top of the lifting frame 3. Two right-angle tubes 5 are symmetrically fixed through the top of the support plate 4, and the two right-angle tubes 5 are respectively placed on both sides of the lifting frame 3. A horizontal piston rod 6 is airtightly connected to the opposite end of each of the two right-angle tubes 5. A clamping plate 7 is fixedly installed at the opposite end of each of the two horizontal piston rods 6. The two clamping plates 7 are rectangular and slide against the top of the lifting frame 3 to prevent the clamping plates 7 from rotating and to ensure the stability of the movement of the clamping plates 7.

[0028] The lower ends of the two right-angle tubes 5 are airtightly connected to vertical piston rods 8. The lower ends of the two vertical piston rods 8 are fixedly installed with connecting plates 9. The bottom of the support plate 4 is fixedly installed with a U-shaped frame 10, and the U-shaped frame 10 slides and fits on the surface of the lifting frame 3. The bottom of the U-shaped frame 10 is fixedly installed with an electric push rod 11 for driving the connecting plate 9 to move vertically. When the electric push rod 11 is started, it drives the connecting plate 9 upward, causing the two vertical piston rods 8 to move upward in the two right-angle tubes 5 respectively. By compressing the gas in the two right-angle tubes 5, the two horizontal piston rods 6 are pushed, causing the two clamping plates 7 to move towards each other until they press against the linear motor on the support plate 4, thus achieving the clamping and fixing of the linear motor.

[0029] A vertical adjustment assembly is used to drive the lifting frame 3 to move vertically within the slide 2. The vertical adjustment assembly includes a vertical lead screw 12 rotatably mounted at the bottom of the slide 2, and the vertical lead screw 12 is threaded through the top of the lifting frame 3. A first drive motor 13 for driving the vertical lead screw 12 to rotate is fixedly mounted on the top of the fixed frame 1. The first drive motor 13 is started to drive the vertical lead screw 12 to rotate, thereby driving the lifting frame 3 to move vertically along the slide 2 to achieve height adjustment of the linear motor to be installed.

[0030] A lateral adjustment assembly is used to drive the support plate 4 to move laterally on the lifting frame 2. The lateral adjustment assembly includes a cavity opened in the lifting frame 3, in which a second drive motor 14 is fixedly installed. A lateral lead screw 15 is fixedly installed at the drive end of the second drive motor 14. A slider 16 is threadedly connected to the surface of the lateral lead screw 15. The slider 16 extends movably through to the top of the lifting frame 3 and is fixedly installed at the bottom of the support plate 4. A sliding hole is opened at the top of the lifting frame 3, and the sliding hole is slidably connected to the slider 16, which serves to limit the sliding of the slider 16.

[0031] This utility model also provides a direct-drive CNC machine tool, including the linear motor mounting device described above, thus achieving all the technical effects of the linear motor mounting device described above, which will not be described here.

[0032] The working principle of this utility model is as follows:

[0033] When in use, first place the linear motor to be installed on the support plate 4, then start the electric push rod 11 to drive the connecting plate 9 upward and drive the two vertical piston rods 8 to move upward in the two right-angle tubes 5 respectively. By compressing the gas in the two right-angle tubes 5, the two horizontal piston rods 6 are pushed to make the two clamping plates 7 move towards each other until they press against the linear motor on the support plate 4, thus achieving the clamping and fixing of the linear motor.

[0034] Subsequently, if the position of the linear motor to be installed needs to be adjusted, the first drive motor 13 is started to drive the vertical lead screw 12 to rotate, which drives the lifting frame 3 to move vertically along the slide groove 2, so as to adjust the height of the linear motor to be installed. Alternatively, the second drive motor 14 can be started to drive the horizontal lead screw 15 to rotate, which controls the slider 16 to move the support plate 4 horizontally along the slide hole, so as to adjust the horizontal position of the linear motor to be installed.

[0035] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
