DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a bearing turning mechanism comprises a lathe 1, a triangular chuck 2 arranged on the lathe 1 for supporting a workpiece, a turning tool 3 arranged on the base of the lathe 1 and moving on the base, and also comprises a loading mechanism for realizing sequential loading of the workpieces and a storage mechanism for storing the workpieces after turning. When working, the workpieces are sequentially loaded through the loading mechanism and the turning of the workpieces is completed. The workpieces after processing are stored in the storage mechanism, thereby improving the turning efficiency of medium and rough workpieces.

[0030] like Figure 2 As shown, the loading mechanism includes a bracket 4, a storage slot 5 obliquely arranged on the bracket 4, a lifting slot 6 arranged on the bracket 4 and lifted and lowered on the bracket 4, a positioning mechanism arranged on the lifting slot 6 for positioning the annular workpiece, and a pushing mechanism for pushing the annular workpiece in the lifting slot 6 onto the triangular chuck 2; when the lifting slot 6 rises to the uppermost end, the workpiece at the front end of the storage slot 5 enters the lifting slot 6, the positioning mechanism positions the workpiece, the lifting slot 6 descends, and the workpiece is transported to the triangular chuck 2, the pushing mechanism pushes the workpiece onto the triangular chuck 2 and fixes the workpiece, and then the turning tool moves backward to turn the workpiece, thereby realizing automatic loading of the workpiece.

[0031] like Figure 3 and Figure 4 When the lifting slot 6 is lifted up, the upper end of the rotating frame 8 contacts with the limiting plate 9, and the rotating frame 8 overcomes the elastic force of the stretching spring and swings upward at the right end, thereby driving the positioning rod 7 to move up, and the positioning rod 7 will not interfere with the workpiece in the storage slot 5 entering the lifting slot 6; then the lifting slot 6 descends, and the upper end of the rotating frame 8 is separated from the limiting plate 9. At this time, the rotating frame 8 swings downward under the action of the stretching spring 10, and the positioning rod 7 descends to prevent the workpiece from falling from the lifting slot 6 when the lifting slot 6 is lifted.

[0032] like Figure 5 As shown, the storage mechanism includes a first movable seat 11 arranged on the base of the lathe 1 and moving left and right on the base of the lathe 1, and a support rod 12 arranged on the first movable seat 11. After the cutter completes cutting, the cutter moves forward and exits. At this time, the first movable seat 11 moves to the left, and the left end position of the support rod 12 corresponds to the position of the triangular chuck 2. After cutting is completed, the processed workpiece falls onto the support rod 12 and is stored on the support rod 12.

[0033] like Figure 5 As shown, the second movable seat 13 on the base of the lathe 1 can move forward and backward, and the turning tool 3 is installed on the second movable seat 13. The front end of the base of the lathe 1 is provided with a hydraulic cylinder for driving the second movable seat 13 to move forward and backward. Of course, it can also be in the form of a lead screw nut. This is a prior art and will not be described in detail here. When the second movable seat 13 moves forward and backward, the first movable seat 11 moves left and right under the action of the linkage mechanism. When the second movable seat 13 moves backward, the first movable seat 11 moves rightward under the action of the linkage mechanism. When the second movable seat 13 moves forward, the first movable seat 11 moves leftward under the action of the linkage mechanism.

[0034] like Figure 5 As shown, the linkage mechanism includes a driving plate 14 arranged on the side of the second moving seat 13, and a guide plate 15 arranged on the side of the first moving seat 11. The guide plate 15 is provided with a guide groove 16, and the guide groove 16 includes an inclined portion and a straight portion arranged at both ends of the inclined portion. The inclined portion is inclined backward from right to left, and a driving rod 17 is provided at one end of the outer side of the driving plate 14 to cooperate with the guide groove 16. After the workpiece is cut, the second moving seat 13 moves forward, and under the action of the guide groove 16 and the driving rod 17, the first moving seat 11 moves to the left, and the left end of the support rod 12 goes deep into the middle of the workpiece, which is convenient for recycling the workpiece that has been processed. After the next workpiece is loaded, the second moving seat 13 moves backward, and the cutter cuts the workpiece. At this time, under the action of the guide groove 16 and the driving rod 17, the first moving seat 11 moves to the right to make way. The mechanical linkage method is adopted to realize the linkage between the forward and backward movement of the second moving seat 13 and the left and right movement of the first moving seat 11, which is low in cost and long in service life.

[0035] like Figure 1 As shown, the storage slot 5 is inclined downward from the back to the front.

[0036] like Figure 2 As shown, the lifting slot 6 is connected to the bracket 4 via a guide rail slider, a lifting hydraulic cylinder 18 is provided at the upper end of the bracket 4, a cylinder end of the lifting hydraulic cylinder 18 is rotatably connected to the upper end of the bracket 4, a rotating plate 19 is provided at the piston rod end of the lifting hydraulic cylinder 18 which is rotatably connected to the lifting slot 6, and the lifting slot 6 is driven to rise and fall by the extension and retraction of the piston rod of the lifting hydraulic cylinder 18.

[0037] like Figure 2 and Figure 3 As shown, the ejection mechanism includes a push rod 20 that passes through the side wall of the lifting groove 6 and is slidably connected with the side wall of the lifting groove 6, and a push plate 21 arranged at one end of the inner side of the push rod 20. A compression spring 22 is arranged on the push rod 20, and an end plate 23 is arranged at one end of the outer side of the push rod 20. The inner end of the compression spring 22 contacts the lifting groove 6, and the outer end of the compression spring 22 contacts the end plate 23. A pressure rod 24 that cooperates with the end plate 23 is arranged at the lower end of the rotating plate 19. Under normal circumstances, under the action of the compression spring 22, the push rod 20 is located at the outermost end, a groove is arranged on the inner wall of the lifting groove 6, and the push plate 21 is located in the groove. When the piston rod of the lowering hydraulic cylinder 18 extends until the lifting groove 6 drops to the lowermost end, the piston rod of the lowering hydraulic cylinder 18 continues to extend, and the pressure rod 24 presses down the push rod 20. The push rod 20 overcomes the elastic force of the compression spring 22, and the push plate 21 extends to push the workpiece in the lifting groove 6 to the triangular chuck 2 for fixing.

[0038] like Figure 3 As shown, a baffle 25 is provided at the rear end of the lifting slot 6. When the lifting slot 6 descends, the baffle 25 blocks the workpieces in the storage slot 5 to prevent the remaining workpieces from falling.
