Description

Technical Field

[0001] The invention relates to the field of machinery, and in particular to a non-destructive straightening device for non-destructively straightening a long shaft part. Background Art

[0002] Due to the characteristics of their shape, long shaft parts are prone to bending and deformation during long-term use, affecting their normal use. For example, a lead screw is a slender, flexible shaft part with high precision. Its main function is to convert rotational motion into linear motion, or torque into axial repeated force, so it has high requirements in terms of precision, strength and wear resistance. During processing or heat treatment, the combined effects of cutting force, centrifugal force, deadweight and heat will cause the lead screw to bend and deform, affecting the use of the ball screw. Therefore, it is necessary to straighten the bending deformation of the shaft products so that their straightness meets certain requirements for normal operation.

[0003] However, there is a problem in the straightening process: the traditional straightening method is generally carried out by straightening through multiple straightening rollers or cylinders, such as patents CN209736378U and CN213079609U. This type of method is a direct contact straightening between the non-destructive straightening device and the long-axis parts. During this process, the long-axis parts are very likely to be scratched, worn, etc. due to the friction generated by the non-destructive straightening device. Even if the straightness of the long-axis parts meets the use requirements, the defective parts will affect the normal function of the entire long-axis parts, and in severe cases will lead to direct scrapping.

The electromagnetic generating device 310 is provided on the straightening assembly 300. The electromagnetic generating device 310 is used to straighten the long-axis part 900 after power is applied by applying a magnetic field; the detection assembly 400, the detection assembly 400 is arranged on the straightening assembly 300, and the detection assembly 400 is used to detect the deformation of the long-axis part 900; the demagnetization and conveying assembly 500, the demagnetization and conveying assembly 500 is connected to the end of the support assembly 200 away from the power assembly 100, and the demagnetization and conveying assembly 500 is used to drive the long-axis part 900 to move, so that the long-axis part 900 can move to the first pneumatic chuck 110 at the beginning of straightening.

[0042] For example, before the lossless straightening device starts working, the power assembly 100 and the support assembly 200 are placed adjacent to the straightening assembly 300, and the demagnetization and conveying assembly 500 drives the long-axis part 900 placed on the conveyor belt 520 to move through the rotation of the conveyor belt roller 530. When one end of the long-axis part 900 passes through the support assembly 200 and the straightening assembly 300 and is transported to the power assembly 100, the first pneumatic chuck 110 of the power assembly 100 automatically clamps the workpiece, and the power assembly 100 pulls the long-axis part 900 to slide to the left through the second guide rail 600 and maintains the same speed as the demagnetization and conveying assembly 500. The power assembly 100 moves according to the long-axis zero input by the system. The length of the long axis part 900 is automatically stopped and locked on the first guide rail 700 through the lower end nut.

[0052] For example, the detection component 400 is fixed on the straightening component 300, and the detection head 410 on the detection component 400 is placed on the outside of the electromagnetic generator 310 to prevent the electromagnetic generator 310 from generating a magnetic field that interferes with the detection head 410 and affects the detection accuracy when the electromagnetic generator 310 is working; the detection head 410 is used to detect the deformation of the long-axis part 900; the grating ruler 420 is connected to the detection head 410, and the grating ruler 420 is provided with a slot, which is used to ensure that the detection head 410 has space to slide up and down during detection, so that the detection head 410 can detect the deformation of the long-axis part 900; the detection bracket 460 is connected to the detection head 410, and the bottom of the detection bracket 460 is provided with a spring 470, which provides a force and range of action for the detection head 410 to achieve up and down jumping. According to the jumping value detected by the detection component 400, the electromagnetic generator 310 can automatically adjust the magnetic field size, and then automatically adjust the force applied to the long-axis part 900.

[0053] Furthermore, the detection component 400 also includes: a pressure head 440. When the long-axis part 900 is in the detection state, the pressure head 440 and the detection head 410 are separated, and the detection head 410 contacts the long-axis part 900 to detect the runout value; a pressure head bracket 430, which is connected to the pressure head 440; and a pressure head fixing block 450, on which the pressure head bracket 430 is fixed.

[0054] For example, when the non-destructive straightening device is working, when it is detected that the long-axis part 900 is in a non-detection state, the pressure head 440 is pressed down, and the lowest end of the pressure head 440 is against the detection head 410. The detection head 410 can be separated from the long-axis part 900 through the slot on the grating scale 420. When it is detected that the long-axis part 900 is in the detection state, the pressure head 440 is separated from the detection head 410, and the detection head 410 can contact the long-axis part 900 to detect the runout value.

[0055] For further information, see Fig.10 The demagnetization and conveying component 500 includes: a conveyor belt 520; a conveyor belt roller 530, the conveyor belt roller 530 is connected to the conveyor belt 520, and the conveyor belt 520 passes through the conveyor belt roller 530; a roller bracket 540, the roller bracket 540 is provided with the conveyor belt roller 530; a demagnetization and conveying part bracket 550, and the roller bracket 540 is fixed on the demagnetization and conveying part bracket 550.

[0056] For example, the demagnetization and conveying part bracket 550 is used to support and fix the conveyor belt 520 and the roller bracket 540. The roller bracket 540 is provided with a conveyor belt roller 530. The conveyor belt 520 passes through the conveyor belt roller 530 and is connected to the conveyor belt roller 530, so that the conveyor belt roller 530 can roll on the roller bracket 540, thereby driving the movement of the conveyor belt 520. The conveyor belt roller 530 is fixed on the side close to the support assembly 200, so that the long axis part 900 can be better moved between the support assembly 200 and the demagnetization and conveying assembly 500.

[0057] Furthermore, the demagnetization and conveying assembly 500 also includes: a demagnetization machine 510 , which is placed on the demagnetization and conveying unit bracket 550 , and the demagnetization machine 510 is used to demagnetize the long-axis part 900 .

[0058] For example, after the straightening is completed, the demagnetizer 510 can demagnetize the long-axis part 900. The demagnetizer 510 is fixed on the demagnetization and conveying part bracket 550 close to the side of the supporting assembly 200, so that all parts of the long-axis part 900 can be demagnetized.

[0059] Furthermore, the non-destructive straightening device also includes: a second guide rail 600, and the second guide rail 600 is used to realize the movement of the power component 100 and the straightening component 300.

[0060] For example, the second guide rail 600 matches the first groove 196 and the third groove 346 to facilitate the movement of the power component 100 and the straightening component 300. At the same time, the second guide rail 600 provides a linear environment to make the movement of the power component 100 and the straightening component 300 more stable and horizontal, thereby improving the straightening accuracy of the long axis part 900.
