DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 , the utility model provides an embodiment: a chamfering device for bearing steel processing, comprising a processing table 1, a starting chuck 2 is arranged on one side of the top of the processing table 1, and a support plate 6 is installed on the top of the processing table 1 opposite to the starting chuck 2, and an electric telescopic rod 5 is installed on the side of the support plate 6 close to the starting chuck 2, a guide groove 8 is opened on the top of the processing table 1, and a guide seat 9 is installed inside the guide groove 8, guide rods 7 are installed on both sides of the guide seat 9, and one end of the guide rod 7 passes through the outside of the support plate 6, a fixed box 4 is connected to the inside of the guide seat 9, and one end of the fixed box 4 is connected to one end of the electric telescopic rod 5, a first motor 10 is fixed inside the fixed box 4, and a rotating disk 3 is fixedly installed on the output end of the first motor 10, the rotation center of the rotating disk 3 is arranged colinearly with the central position axis of the starting chuck 2, and a diameter adjustment mechanism 15 is arranged inside the rotating disk 3;

[0024] The diameter adjustment mechanism 15 includes a second motor 1501 installed at the bottom end of the rotating disk 3, and the top of the second motor 1501 is connected to a rotating disk 1502 through an output shaft, and eccentric shafts 1503 are installed at both ends of one side of the rotating disk 1502, and the outside of the eccentric shaft 1503 is sleeved with a connecting rod 1504, and one end of the connecting rod 1504 is connected to one side of the movable rod 14;

[0025] The connecting rod 1504 is rotatably connected to the eccentric shaft 1503, the connecting rod 1504 is hinged to the movable rod 14, and the rotation axis of the rotating disk 1502 coincides with the rotation axis of the rotating disk 3;

[0026] Specifically, Figure 1 , Figure 3 As shown, when in use, the eccentric shaft 1503 is rotated to synchronize the distance between the movable processing table 1 and the left and right eccentric shafts 1503, thereby realizing the synchronous movement between the left and right movable blocks 11, so as to ensure the synchronous movement between the outer chamfering cutter 12 and the inner chamfering cutter 13 and realize the chamfering effect on bearing steels of different diameters, thereby improving the efficiency and reducing the steps of the overall operation;

[0027] And movable rods 14 are installed on both sides of the diameter adjustment mechanism 15;

[0028] The movable rod 14 is symmetrically distributed about the central axis of the rotating disk 3. The two ends of the movable rod 14 respectively form a left-right sliding structure with the rotating disk 3 through the cooperation of the sliding groove and the guide hole. At the same time, the moving direction of the movable rod 14 coincides with the diameter line of the rotating disk 3.

[0029] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, the moving direction of the movable rod 14 is restricted so that the connecting rod 1504 is tilted along with the rotation of the rotating disk 1502, so that the connecting rod 1504 pulls the movable rod 14 inward or pushes it outward, so that the left and right movable rods 14 move radially, thereby realizing the contraction or expansion of the left and right chamfering cutters.

[0030] One end of the movable rod 14 extends to the outside of the rotating disk 3 and is installed with a movable block 11. At the same time, the movable block 11 moves left and right along the radius line of the rotating disk 3 under the action of the movable rod 14. A detachable mechanism 16 is provided inside the movable block 11, and an outer chamfering knife 12 and an inner chamfering knife 13 are respectively installed on both sides of the top of the detachable mechanism 16.

[0031] The detachable mechanism 16 includes positioning grooves 1601 uniformly provided at the top of the movable block 11, and a through hole 1602 is horizontally penetrated and connected between the positioning grooves 1601, a positioning block 1605 is installed inside the positioning groove 1601, and a positioning hole 1606 is provided inside the positioning block 1605, and a positioning rod 1603 is penetrated and connected between the positioning hole 1606 and the through hole 1602;

[0032] The positioning grooves 1601 are distributed at equal intervals on the movable block 11, and two positioning blocks 1605 are provided on the movable block 11, and an inner chamfering knife 13 and an outer chamfering knife 12 are welded on the two positioning blocks 1605, respectively.

[0033] A threaded head 1604 is welded to one end of the positioning rod 1603, and the threaded head 1604 is threadedly connected to the outermost end of the through hole 1602;

[0034] Specifically, Figure 3 and Figure 4 As shown, when in use, the threaded head 1604 is connected to the threaded connection at the outermost end of the through hole 1602 to achieve a further fixing effect on the positioning rod 1603, preventing the positioning rod 1603 from moving left and right at will, thereby ensuring its fixing effect on the positioning block 1605 and ensuring the stability of the external chamfering cutter 12 and the internal chamfering cutter 13 during the processing.

[0035] Working principle: When the utility model is used, firstly, the corresponding outer chamfering knife 12 and inner chamfering knife 13 are used according to the chamfering angle, and the positioning block 1605 is inserted into the interior of the positioning groove 1601. According to the thickness of the bearing steel, the spacing between the two positioning blocks 1605 is adjusted, and then the positioning rod 1603 is inserted horizontally through the through hole 1602 and the positioning hole 1606, and then the thread head 1604 is screwed to make it penetrate into the interior of the through hole 1602 to ensure the insertion stability of the positioning rod 1603;

[0036] Secondly, the bearing steel is inserted into one side of the starting chuck 2, and the electric telescopic rod 5 is started to extend, so that it pushes the fixed box 4 to approach the starting chuck 2, so that the guide seat 9 slides along the inside of the guide groove 8, and the outer chamfering knife 12 and the inner chamfering knife 13 on the rotating disk 3 correspond to the outer edge and the inner edge of the bearing steel, and the first motor 10 is started synchronously to drive the rotating disk 3 to rotate, and then the outer chamfering knife 12 and the inner chamfering knife 13 perform synchronous chamfering processing on the inside and outside of the bearing steel;

[0037] Finally, the second motor 1501 can be started to rotate the turntable 1502, and then the eccentric shaft 1503 can be moved synchronously, so that the eccentric shaft 1503 pulls one end of the connecting rod 1504 to move. Since the movable rod 14 can only move along the diameter direction of the rotating disk 3, the connecting rod 1504 is tilted, and the other end of the connecting rod 1504 has an inward pulling effect on the movable rod 14, so that the two movable rods 14 are close to each other, thereby changing the distance between the left and right outer chamfering knives 12 and the two inner chamfering knives 13, so that they can meet the chamfering effect on bearing steels of different diameters.
