Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a clamping mechanism for CNC machine tools that is easy to adjust the angle. Background Technology

[0002] CNC machine tools, short for Computer Numerical Control machine tools, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] The existing CNC machine tool clamping mechanism fixes the part under the machine tool, but it cannot adjust the angle of the part. The existing CNC machine tool clamping mechanism fixes the part to the clamping table with several bolts, which is a relatively cumbersome process.

[0004] Therefore, we propose a clamping mechanism for CNC machine tools that is easy to adjust the angle. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping mechanism for CNC machine tools that facilitates angle adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamping mechanism for CNC machine tools with easily adjustable angles includes a bracket, which is U-shaped. A worktable is rotatably connected inside the bracket via a rotating shaft. A support is fixedly installed on the top surface of the worktable. Two sliding rods are movably installed on both sides of the support. Four clamps are fixedly installed on the top surfaces of the two sliding rods. A clamping assembly is installed inside the support. A protective shell is fixedly installed on the side of the bracket away from the support. A support plate is fixedly installed at the bottom of the protective shell. An angle adjustment assembly is installed on the top surface of the support plate.

[0008] As a further embodiment of this utility model: the clamping assembly includes a servo motor, the servo motor is fixedly installed on the bottom surface of the worktable, a gear is rotatably connected to the top surface of the worktable, the gear is fixedly connected to the output end of the servo motor, and two toothed rods are meshed on both sides of the gear, and the two toothed rods are respectively fixedly connected to two sliding rods.

[0009] As a further improvement of this utility model: two limiting rods are fixedly installed on the top surface of the workbench, and the two limiting rods are slidably connected to two sliding rods respectively.

[0010] As a further embodiment of this utility model: the angle adjustment component includes an electric push rod, the electric push rod is fixedly installed on the top surface of the support plate, and a telescopic toothed rod is fixedly connected to the top end of the electric push rod.

[0011] As a further embodiment of this utility model: a sliding sleeve is fixedly installed on the side of the protective shell near the telescopic toothed rod, the sliding sleeve is slidably connected to the telescopic toothed rod, and a second gear is rotatably connected inside the protective shell, the second gear being meshed with the telescopic toothed rod.

[0012] As a further improvement of this utility model, the second gear is fixedly connected to the worktable.

[0013] Compared with the prior art, this utility model provides a clamping mechanism for CNC machine tools that is easy to adjust the angle, and has the following beneficial effects:

[0014] 1. This utility model, by installing a clamping assembly, starts a servo motor to drive a gear on the top surface of the worktable to rotate. The gear meshes with two toothed rods on both sides and rotates. One toothed rod is fixedly connected to a slide rod, and the other toothed rod is fixedly connected to another slide rod. The two toothed rods move towards each other, and their movable ends are slidably connected to the two slide rods respectively. The two slide rods move and approach on two limit rods, driving four clamps to clamp and fix the parts.

[0015] 2. This utility model, by installing an angle adjustment component, activates the electric push rod on the support plate. The electric push rod pushes upward, causing the telescopic gear rod inside the sliding sleeve on one side of the protective shell to move upward. The telescopic gear rod meshes with the second gear inside the protective shell, causing the second gear to rotate. The second gear causes the worktable to tilt to the right, thereby causing the parts to tilt to the right. Conversely, the electric push rod retracts downward, causing the telescopic gear rod to move downward. The telescopic gear rod meshes with the second gear, causing the second gear to rotate in the opposite direction. The second gear causes the worktable to tilt to the left, thus improving the efficiency of the device's angle adjustment.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0022] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A clamping mechanism for CNC machine tools with easily adjustable angles, such as... Figures 1-4 As shown, the system includes a bracket 1, which is U-shaped. Inside the bracket 1, a worktable 2 is rotatably connected via a pivot. A support platform 3 is fixedly installed on the top surface of the worktable 2. Two sliding rods 4 are movably installed on both sides of the support platform 3. Four clamps 5 are fixedly installed on the top surface of the two sliding rods 4. A clamping assembly is installed inside the support platform 3. A protective shell 6 is fixedly installed on the side of the bracket 1 away from the support platform 3. A support plate 7 is fixedly installed at the bottom of the protective shell 6. An angle adjustment assembly is installed on the top surface of the support plate 7.

[0025] like Figures 1-4As shown, the clamping assembly includes a servo motor 8. The servo motor 8 is fixedly installed on the bottom surface of the worktable 2. A gear 9 is rotatably connected to the top surface of the worktable 2. The gear 9 is fixedly connected to the output end of the servo motor 8. Two toothed rods 10 are meshed on both sides of the gear 9. The two toothed rods 10 are fixedly connected to two slide rods 4 respectively. Two limit rods 11 are fixedly installed on the top surface of the worktable 2. The two limit rods 11 are slidably connected to the two slide rods 4 respectively. When the servo motor 8 is started, the gear 9 on the top surface of the worktable 2 rotates. The gear 9 meshes with the two toothed rods 10 on both sides and rotates. One toothed rod 10 is fixedly connected to one slide rod 4, and the other toothed rod 10 is fixedly connected to the other slide rod 4. The two toothed rods 10 move towards each other, and their movable ends are slidably connected to the two slide rods 4 respectively. The two slide rods 4 move and approach on the two limit rods 11, driving the four clamps 5 to clamp and fix the parts.

[0026] like Figures 1-3 As shown, the angle adjustment assembly includes an electric push rod 12. The electric push rod 12 is fixedly installed on the top surface of the support plate 7. A telescopic gear 13 is fixedly connected to the top of the electric push rod 12. A sliding sleeve 14 is fixedly installed on the side of the protective shell 6 near the telescopic gear 13. The sliding sleeve 14 is slidably connected to the telescopic gear 13. A gear 15 is rotatably connected inside the protective shell 6. The gear 15 meshes with the telescopic gear 13. The gear 15 is fixedly connected to the worktable 2. When the electric push rod 12 on the support plate 7 is started, the electric push rod 12 pushes upward, causing the telescopic gear 13 inside the sliding sleeve 14 on one side of the protective shell 6 to move upward. The telescopic gear 13 meshes with the gear 15 inside the protective shell 6, causing the gear 15 to rotate. The gear 15 causes the worktable 2 to tilt to the right, thereby causing the parts to tilt to the right. Conversely, the electric push rod 12 retracts downward, causing the telescopic gear 13 to move downward. The telescopic gear 13 meshes with the gear 15, causing the gear 15 to rotate in the opposite direction. The gear 15 causes the worktable 2 to tilt to the left.

[0027] Working principle: First, move the device to the CNC machine tool processing site and connect the device to the factory power supply. Place the part to be processed on the support platform 3. Start the servo motor 8 to drive the gear 9 on the top surface of the worktable 2 to rotate. The gear 9 meshes with two toothed rods 10 on both sides and rotates. One toothed rod 10 is fixedly connected to a slide rod 4, and the other toothed rod 10 is fixedly connected to another slide rod 4. The two toothed rods 10 move towards each other, and their movable ends are slidably connected to the two slide rods 4 respectively. The two slide rods 4 move and approach on the two limit rods 11, driving the four clamps 5 to clamp and fix the part.

[0028] During processing, the angle of the part needs to be adjusted. The electric push rod 12 on the support plate 7 is activated, and the electric push rod 12 pushes upward, causing the telescopic gear 13 inside the sliding sleeve 14 on one side of the protective shell 6 to move upward. The telescopic gear 13 meshes with the second gear 15 inside the protective shell 6, causing the second gear 15 to rotate. The second gear 15 causes the worktable 2 to tilt to the right, which in turn causes the part to tilt to the right. Conversely, the electric push rod 12 retracts downward, causing the telescopic gear 13 to move downward. The telescopic gear 13 meshes with the second gear 15, causing the second gear 15 to rotate in the opposite direction. The second gear 15 causes the worktable 2 to tilt to the left, which improves the efficiency of the device's angle adjustment.
