DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be further described below with reference to embodiments and in conjunction with the accompanying drawings.

[0025] Example:

[0026] This embodiment is an automatic tooth rolling machine, such as Figure 1 and Figure 2 As shown, the system includes a control box, a processing chamber 1, a first and second rolling mechanism 3, a second rolling mechanism 4, a feed support frame 2, and a tooth alignment detection mechanism 5. The first and second rolling mechanisms 3, 4 are slidably mounted on the left and right sides of the processing chamber, and the feed support frame 2 is located at the feed end of the processing chamber 1. Two tooth alignment detection mechanisms 5 are provided, slidingly mounted on the top surface of the processing chamber and corresponding to the first and second rolling mechanisms 3, 4, respectively. The feed support frame 2 comprises two opposing vertical plates, with upper and lower roller assemblies positioned between the plates, leaving a gap between the rollers for the raw material to enter. The first and second rolling mechanisms, as well as the tooth alignment detection mechanism, are all electrically connected to the control box.

[0027] The processing chamber's bottom surface is divided into two sections, left and right. The left section is equipped with transverse rails 6, and the right section is equipped with longitudinal rails 7. The first rolling mechanism 3 slides on the transverse rails, while the second rolling mechanism 4 slides on the longitudinal rails. Outside the processing chamber, a first hydraulic cylinder 9 and a second hydraulic cylinder 8 are located. The first hydraulic cylinder 9 is located on the left side of the processing chamber. The piston rod of the first hydraulic cylinder passes through the left side wall of the processing chamber and is fixed to the first rolling mechanism 3, pushing the first rolling mechanism along the transverse rails. The second hydraulic cylinder 8 is located on the right side of the processing chamber's discharge end. The piston rod of the second hydraulic cylinder is fixed to the second rolling mechanism 4, pushing the second rolling mechanism along the longitudinal rails. Both the first and second hydraulic cylinders are controlled by a control box.

[0028] Both the first and second rolling mechanisms include a motor 10, a spindle, a rolling wheel 12, and a protective housing 11. The motor is located at the rear end of the protective housing. The spindle is rotatably mounted within the protective housing 11 and is connected to the motor. Notches are defined on opposing sides of the front halves of the two protective housings. The rolling wheel 12 is fixed to the spindle and positioned within the notches. The motor is electrically connected to and controlled by a control box.

[0029] like Figure 3 Said tooth detection mechanism comprises two, including a first tooth detection mechanism and a second tooth detection mechanism, the first tooth detection mechanism corresponds to the first tooth rolling mechanism, and the second tooth detection mechanism corresponds to the second tooth rolling mechanism. The first pair of teeth detection mechanism and the second pair of teeth detection mechanism both include a slide 13, a cylinder 14, a grating scale 16, a detection block 21 and a frame. The slide 13 is arranged on the top surface of the working chamber. The sliding directions of the two slides are respectively the same as the sliding directions of the first rolling mechanism and the second rolling mechanism, that is, the slide of the first pair of teeth detection mechanism extends horizontally, and the slide of the second pair of teeth detection mechanism extends longitudinally. The cylinder 14 is fixedly arranged on the slide of the slide 13, and the frame is fixedly arranged on the piston rod of the cylinder 14. The lower end of the detection block 21 is rotatably provided with a threaded barrel 20 that matches the rolling wheels in the first rolling mechanism and the second rolling mechanism. The detection block 21 is slidably arranged on the frame, the grating scale 16 is fixedly arranged on the frame and the reading head 17 of the grating scale is fixedly arranged on the detection block 21. The reading head and the slide of the grating scale are both electrically connected to the control box. When the first hydraulic cylinder and the second hydraulic cylinder push the first rolling mechanism and the second rolling mechanism to slide, the two slides also slide accordingly and the sliding displacement of the slides is the same as the sliding displacement of the first rolling mechanism and the second rolling mechanism, ensuring that the two tooth detection mechanisms and the first rolling mechanism and the second rolling mechanism remain relatively stationary during sliding.

[0030] The frame includes a top plate 22, a vertical connecting rod 15, and a horizontal slide 18. The top end of the top plate 22 is fixed to the piston rod of the cylinder 13. The vertical connecting rod 15 has two ends located at the bottom end of the top plate. The grating scale 16 is horizontally installed between the middle parts of the vertical connecting rods 15. The horizontal slide is located between the lower ends of the vertical connecting rods. The detection block slides on the horizontal slide. A water spray pipe 19 is installed on each side of the horizontal slide. The water spray pipe 19 can flush debris on the rolling wheel during the tooth alignment to ensure the accuracy of the tooth alignment. It can also output coolant during rolling to prevent the rolling wheel from overheating. The horizontal slides in the two tooth detection mechanisms are parallel to the axis of the rolling wheel.

[0031] The cylinder's extension and retraction can change the height of the threaded barrel, allowing the barrel to contact or separate from the rolling wheel. When the barrel contacts the rolling wheel, the threads on the barrel can engage with the threads on the rolling wheel. As the rolling wheel rotates, the barrel can move in sequence, and the readings taken by the reading heads will also change accordingly. By calculating the difference between the readings taken by the two reading heads, it is possible to detect whether the two rolling wheels are aligned. At the same time, to ensure the accuracy of the alignment, when the barrel and the corresponding rolling wheel are aligned in the alignment detection mechanism, the axes of the two barrels are parallel to the plane containing the axes of the corresponding rolling wheels. That is, the axis of the barrel in the first alignment detection mechanism and the axis of the rolling wheel in the first rolling mechanism are parallel to the plane containing the axis of the barrel in the second alignment detection mechanism and the axis of the rolling wheel in the second rolling mechanism.

[0032] Correspondingly, the present invention also provides an automatic tooth alignment method, comprising the following steps:

[0033] S1: Adjust the displacement of the first hydraulic cylinder and the slide of the tooth detection mechanism corresponding to the first rolling mechanism so that the axes of the two threaded barrels are parallel to the plane where the axes of the corresponding rolling wheels are located;

[0034] S2: Spray water from the water pipe to clean the debris on the surface of the rolling wheel. During the water spraying process, the rolling wheel rotates at least one circle to ensure that the debris on the surface of the rolling wheel is washed away;

[0035] S3: The cylinders of the two tooth detection mechanisms extend to make the threaded barrel and the rolling wheel collide with each other;

[0036] S4: The two rolling rollers rotate to make the threads on the threaded barrel engage with the threads on the rolling rollers;

[0037] S5: A single rolling wheel rotates and the difference between the two grating scale readings is calculated in real time. When the difference between the two grating scale readings is an integer multiple of the rolling wheel pitch, the rolling wheel stops rotating, and the thread alignment is completed. When a single rolling wheel rotates, if the corresponding grating scale reading reaches the preset upper or lower limit, the rolling wheel stops rotating and the other rolling wheel starts rotating. When the readings of both grating scales reach the preset upper or lower limit, the two rolling wheels rotate in opposite directions to reset the two reading heads. After reset, the second hydraulic cylinder is controlled to push the second rolling mechanism to slide, and the sliding amount is a non-integer multiple of the rolling wheel pitch.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
