DETAILED DESCRIPTION
[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0021] like Figure 1-6As shown, the utility model is a calibration device for CNC machining, including a CNC lathe body 1, a workbench 2 is provided in the CNC lathe body 1, a cavity 21 is provided in the workbench 2, a motor 22 is provided in the cavity 21, a rotating rod 23 is provided at the output end of the motor 22, a worm 24 is sleeved on the outside of the rotating rod 23, and the worm 24 is laterally meshed and connected to a worm wheel 25. When the CNC lathe body 1 starts to work, the rotating rod 23 at the output end of the motor 22 can start to rotate by turning on the external power switch of the motor 22, a worm 24 is fixedly sleeved on the outside of the rotating rod 23, and the rotation of the rotating rod 23 can drive the worm 24 to rotate, and the worm 24 is laterally meshed and connected to a worm wheel 25, and the rotation of the worm 24 can drive the worm wheel 25 to start rotating synchronously.
[0022] The worm gear 25 is fixedly sleeved with a bidirectional screw rod 26, and the bidirectional screw rod 26 is threadedly connected to a slider 27. The rotation of the worm gear 25 can drive the bidirectional screw rod 26 to start rotating synchronously. A fixed block 11 is fixedly provided on the workbench 2. The fixed block 11 is rotatably connected to the bidirectional screw rod 26 through a bearing. The bidirectional screw rod 26 starts to rotate in the fixed block 11 through the bearing. The rotation of the bidirectional screw rod 26 can drive the slider 27 connected to its external thread to move. The slider 27 is symmetrically threaded on the bidirectional screw rod 26. Two sliders 27 are symmetrically arranged on the bidirectional screw rod 26. The rotation of the bidirectional screw rod 26 can drive the two sliders 27 to move inward or outward.
[0023] A connecting rod 28 is provided on the side of the slider 27, and the connecting rod 28 is connected to the clamping plate 3 on the side. The inward or outward movement of the slider 27 can drive the clamping plate 3 to slide on the workbench 2 through the connecting rod 28. The clamping plate 3 moves inward or outward, and can clamp and fix different materials, which is convenient for quickly clamping and fixing materials during the processing of the CNC lathe body 1.
[0024] The side of the clamping plate 3 is provided with a sleeve 31, and the sleeve 31 is slidably connected to a limit plate 34. One side of the limit plate 34 is connected to a telescopic column 33, and the other side of the limit plate 34 is provided with a clamping rod 35. When the clamping plate 3 is clamped close to the object, when the side wall of the object is irregular, the clamping rod 35 first clamps to the contact surface of the object. When the clamping plate 3 continues to move inward, the clamping rod 35 drives the limit plate 34 to slide in the sleeve 31. The outside of the telescopic column 33 is sleeved with a spring 32, one end of the spring 32 is connected to the inner wall of the sleeve 31, and the other end is connected to the side of the limit plate 34. When the clamping plate 3 slides inward, , the spring 32 is squeezed, and the spring 32 is compressed and deformed, which can generate a rebound force, so that the spring 32 pushes the limit plate 34 to move outward, so that the clamping rod 35 on one side clamps and fixes one side of the object. The side of the clamping plate 3 is provided with a plurality of sleeves 31 arranged at equal distances, and a plurality of sleeves 31 are provided on the side of the clamping plate 3. The clamping rods 35 in the plurality of sleeves 31 clamp the side of the object. The clamping rods 35 in the plurality of sleeves 31 can clamp and fix the side wall of the irregular object, thereby avoiding the small contact area of the clamping plate 3 during the clamping process of the irregular side wall, which is easy to cause unstable clamping, thereby improving the practicality of the device.
[0025] In the above scheme, a sliding rod 12 is fixedly provided on the side of the fixed block 11, and a slider 27 is slidably connected to the sliding rod 12. The sliding rod 12 can play a limiting and guiding role in the rotation of the slider 27, so that the slider 27 can slide stably on the bidirectional screw rod 26.
[0026] In the above solution, an anti-skid pad 36 is fixedly provided on the side of the clamping rod 35. The anti-skid pad 36 provided at the end of the clamping rod 35 can ensure the stability of the material during the clamping process and avoid sliding.
[0027] Working principle:
[0028] When the calibration device for CNC machining is in operation, the object to be CNC machined is placed on the workbench 2, and the external power switch of the motor 22 is turned on. The worm 24 at the output end of the motor 22 drives the worm wheel 25 to rotate, and the rotation of the worm wheel 25 can drive the bidirectional lead screw 26 to rotate. The rotation of the bidirectional lead screw 26 can drive the slider 27 to move inward, and drive the clamping plate 3 connected to the side to move inward, so as to clamp and fix the object. When the clamping rod 35 on the side of the clamping plate 3 contacts the side wall of the object, the clamping rod 35 squeezes the spring 32, so that the spring 32 generates a rebound force, which can stably clamp the object with irregular side walls, thereby improving the practicality of the device.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
