Description

Technical Field

[0001] The utility model belongs to the field of roundness aligning machines, in particular to a double-station roundness aligning machine. Background Art

[0002] A roundness calibration machine refers to a machine that can detect, calculate and calibrate deformed rotating bodies, so that the cylindrical value of the object after calibration can be reduced; as a type of rotating body, the processing of gear ring components requires first cutting the long tube blank into a cylindrical shape of appropriate length, and then placing it in a quenching tank for quenching treatment. After quenching, gear ring components are subject to thermal stress and structural stress, and the subsequent mechanical stress of the grinding tooth root is superimposed, resulting in elliptical deformation of the thin-walled gear ring. When the elliptical deformation is greater than a certain value, the part cannot be processed subsequently and must be calibrated.

[0003] However, in the process of cutting gear ring components from long tube blanks, impurities such as iron filings will be generated. Impurities such as iron filings will adhere to the outer wall of the gear ring, and some impurities will remain even after passing through the quenching pool. Existing roundness calibration machines generally directly detect and calibrate the workpiece. If the outer wall of the workpiece is not polished before detection and burrs, iron filings and other impurities are not removed, the detection accuracy of the outer ring of the workpiece by the detection device will be affected, resulting in inaccurate data collection by the roundness calibration machine, which further affects the subsequent roundness calibration accuracy of the workpiece.

[0023] Specifically, the transmission assembly includes a first motor 10 and a linkage unit. The first motor 10 is fixedly connected to one side of the outer side of the housing 1. The output end of the first motor 10 is fixedly connected to a rotating rod 11. Both ends of the rotating rod 11 extend to the outer side of the housing 1 and are fixedly connected to first pulleys 15 on both sides.

The first pulley 15 and the second pulley 17 are connected by a transmission belt 18. The first fixed cover 6 and the second fixed cover 8 are respectively threadedly connected to the outside of the two lead screws 16. The clamping assembly includes a turntable 2, which is rotatably connected to the top of the rotating column 13. A plurality of groups of arc grooves 3 are provided inside the turntable 2, and a plurality of slide rods 4 are respectively slidably connected to the inside of the arc grooves 3. The outside of the slide rods 4 are fixedly connected to the limit plate 20, and the limit plate 20 is slidably connected to the inside of the shell 1.

[0024] Through the above technical solution, the workpiece to be calibrated is first placed on the pad at the top of the shell 1, and then the first motor 10 is started. The output end of the first motor 10 drives the rotating rod 11 and the worm 12 to rotate, so that the worm 12 drives the worm wheel 14 and the rotating column 13 to rotate through the meshing relationship, thereby driving the top turntable 2 to rotate through the rotating column 13, and the turntable 2 then drives the slide rod 4 to slide under the limit of the limit plate 20 through the internal arc groove 3, until multiple slide rods 4 drive the corresponding limit shaft 5 to tighten the workpiece, thereby achieving the purpose of clamping the workpiece. While the first motor 10 is running, it can drive the first pulley 15 to rotate, and the first pulley 15 then drives the corresponding lead screw 16 to rotate through the second pulley 17 and the transmission belt 18, so that the two lead screws 16 drive the corresponding first fixed cover 6 and the second fixed cover through the threaded connection relationship. The fixed cover 8 slides under the limit of the shell 1 until it drives the grinding block 7 and the transmission roller 9 to be in close contact with the workpiece, and then the second motor 19 is started. The output end of the second motor 19 drives the transmission roller 9 to rotate, which can drive the workpiece to rotate. The limit shaft 5 can rotate with the workpiece. During the rotation of the workpiece, the outer surface of the workpiece can be polished by the grinding block 7, and the burrs and impurities attached to the outer surface of the workpiece are removed, ensuring the smoothness of the outer wall of the workpiece, thereby improving the detection accuracy of the detection device 22 for the workpiece. This device can drive the grinding block 7 and the transmission roller 9 to be in close contact with the workpiece while driving multiple limit shafts 5 to tension the workpiece, and polish and clean the outer wall of the workpiece before detecting and calibrating the workpiece to remove the burrs and impurities, which can effectively improve the subsequent detection accuracy of the outer ring of the workpiece, thereby improving the accuracy of the circular calibration of the outer ring of the workpiece.

[0025] Specifically, the top of the second fixed cover 8 is fixedly connected to the second motor 19, the output end of the second motor 19 extends to the inside of the second fixed cover 8 and is fixedly connected to the transmission roller 9, an electric telescopic rod 21 is installed on the side of the top of the shell 1 away from the calibration device 23, the detection device 22 is rotatably connected to the output end of the electric telescopic rod 21, the shell 1 is arranged into two groups, and the bottom of the two groups of shells 1 are fixedly connected to the circular calibration machine body 24.

[0026] Through the above technical solution, after the outer ring of the workpiece is polished smooth, the output end of the electric telescopic rod 21 is controlled to extend, driving the detection device 22 to contact the workpiece, and then the workpiece is continued to be driven to rotate through the transmission component, so that the outer ring of the workpiece can be detected. After detecting the position where the outer ring of the workpiece needs to be calibrated, the calibration device 23 is started to calibrate the designated position. Two sets of calibration devices are arranged on the top of the calibrating machine body 24 to realize double workstations, so that workpieces of different specifications can be processed.

[0027] When in use, first place the workpiece to be calibrated on the pad on the top of the housing 1, then start the first motor 10, the output end of the first motor 10 drives the rotating rod 11 and the worm 12 to rotate, so that the worm 12 drives the worm wheel 14 and the rotating column 13 to rotate through the meshing relationship, thereby driving the top turntable 2 to rotate through the rotating column 13, and the turntable 2 then drives the slide rod 4 to slide under the limit of the limit plate 20 through the internal arc groove 3, until multiple slide rods 4 drive the corresponding limit shaft 5 to tighten the workpiece, thereby achieving the clamping of the workpiece. The purpose is that the first motor 10 can drive the first pulley 15 to rotate while the first pulley 15 is running, and the first pulley 15 then drives the corresponding lead screw 16 to rotate through the second pulley 17 and the transmission belt 18, so that the two lead screws 16 drive the corresponding first fixed cover 6 and the second fixed cover 8 to slide under the limit of the housing 1 through the threaded connection relationship, until the grinding block 7 and the transmission roller 9 are driven to be close to the workpiece, and then the second motor 19 is started, and the output end of the second motor 19 drives the transmission roller 9 to rotate, which can drive the workpiece to rotate, and the limit shaft 5 can rotate with the workpiece. During the rotation of the workpiece, the outer surface of the workpiece can be polished by the polishing block 7, and the burrs and impurities attached to the outer surface of the workpiece can be removed, so as to ensure the smoothness of the outer wall of the workpiece, thereby improving the detection accuracy of the detection device 22 for the workpiece. The device can drive the polishing block 7 and the transmission roller 9 to be close to the workpiece while driving the multiple limit shafts 5 to tension the workpiece, and polish and clean the outer wall of the workpiece before the workpiece is detected and calibrated to remove the burrs and impurities, which can effectively improve the subsequent outer ring detection accuracy of the workpiece, thereby improving the roundness calibration accuracy of the outer ring of the workpiece. After the outer ring of the workpiece is polished and smooth, the output end of the electric telescopic rod 21 is controlled to extend, driving the detection device 22 to contact the workpiece, and then the workpiece is continued to be driven to rotate through the transmission component, so that the outer ring of the workpiece can be detected.
