DETAILED DESCRIPTION

[0019] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0020] See also Figure 1-Figure 3 , Figure 1 It is a schematic diagram of the three-dimensional structure of the processing device provided by the embodiment of the utility model; Figure 2 This is a schematic diagram of the exploded structure of the processing device provided by an embodiment of the utility model; Figure 3 Schematic diagram of the exploded structure of the processing components in the processing device provided by the embodiment of the present invention. The ship tail shaft bearing sleeve processing device 1 of the present invention includes a connecting sleeve 11 and at least two processing components 12, the processing component 12 includes a processing sleeve 121, a turning tool 122 and an adjusting rod 123, the connecting sleeve 11 and the processing sleeve 121 are both columnar, and the two ends of the connecting sleeve 11 are respectively a first connecting end 111 and a second connecting end 112, and the two ends of the processing sleeve 121 are respectively a third connecting end 1211 and a fourth connecting end 1212, the first connecting end 111 and the third connecting end 1211 have the same outer diameter, and the second connecting end 112 and the fourth connecting end 1211 have the same outer diameter. 212, and the outer diameters of the second connection end 112 and the fourth connection end 1212 are both provided with grooves, the diameter of the groove is the same as the diameter of the third connection end 1211, the first connection end 111 is plug-connected to the tailstock of the lathe, the third connection end 1211 is plug-connected to the groove at the second connection end 112, a slot 1213 is provided on the circumferential surface of the fourth connection end 1212, the turning tool 122 is plugged into the slot 1213, and the adjusting rod 123 is arranged in the fourth connection end 1212 and connected to the turning tool 122 to adjust the insertion depth of the turning tool 122.

[0021] When processing the round tube of the bearing sleeve, the connecting sleeve 11 can be first plugged into the tailstock on the lathe, and the processing sleeve 121 can be plugged into the connecting sleeve 11. At the same time, the claws on the lathe clamp the round tube, and the rotation of the claws is controlled so that the round tube rotates synchronously with the claws. Then, the adjusting rod 123 is rotated to adjust the insertion depth of the turning tool 122 in the slot 1213. Finally, the movement of the tailstock is controlled so that the tailstock drives the processing device 1 to extend into the interior of the round tube, and the turning tool 122 contacts the inner wall of the round tube, thereby realizing the cutting operation on the inside of the round tube under the contact between the turning tool 122 and the round tube.

[0022] Since there are at least two processing components 12, and the fourth connection end 1212 on the processing sleeve 121 is provided with a groove for the third connection end 1211 to be plugged in, the third connection ends 1211 and the fourth connection ends 1212 on at least two processing sleeves 121 can be plugged in to increase the length of the processing device 1, so that the processing device 1 can cut the inner wall of a longer round tube. When processing the round tube, the length of the turning tool 122 in the at least two processing components 12 can be adjusted so that the turning tool 122 close to the round tube performs rough processing on the round tube, and the turning tool 122 far away from the round tube performs fine processing on the round tube, thereby improving the processing efficiency of the round tube.

[0023] Compared with the bearing sleeve processing method in the prior art, the processing device 1 of the present invention can extend into the interior of the circular tube and perform cutting processing on the circular tube, and then directly cut the circular tube after completing the processing of the circular tube to obtain the bearing sleeve. At this time, there is no need to cut the inner surface of the bearing sleeve, which eliminates the clamping process when cutting the bearing sleeve and improves the processing efficiency of the bearing sleeve.

[0024] In an embodiment of the present utility model, the adjusting rod 123 is a screw rod, and a connecting hole 1221 threadedly connected to the screw rod is provided on the turning tool 122. One end of the screw rod is rotatably connected to the inner wall of the fourth connecting end 1212, and the other end is threadedly connected to the threaded hole, so that the operator can adjust the insertion depth of the turning tool 122 in the slot 1213 by rotating the adjusting rod 123, thereby adjusting the cutting amount of the circular tube by the turning tool 122, so as to facilitate the processing of the inner surface of the circular tube to the required size.

[0025] In an embodiment of the present utility model, the processing assembly 12 also includes a rotating rod 124 and two reversing gears 125. The rotating rod 124 is inserted into the interior of the fourth connecting end 1212 from the circumferential surface of the fourth connecting end 1212 and is perpendicular to the adjusting rod 123. The two reversing gears 125 are engaged with each other, and one of the reversing gears 125 is connected to the adjusting rod 123, and the other reversing gear 125 is connected to the rotating rod 124.

[0026] By connecting the two reversing gears 125 to the adjusting rod 123 and the rotating rod 124 respectively, the rotating rod 124 and the adjusting rod 123, which are perpendicular to each other, can be transmitted under the engagement of the reversing gear 125. That is, by rotating the rotating rod 124, the rotating rod 124 can drive the adjusting rod 123 to rotate through the reversing gear 125, and then the adjusting rod 123 drives the insertion depth of the turning tool 122 and the slot 1213.

[0027] Before the turning tool 122 cuts the inner wall of the circular tube profile 2, the connection angle of the processing device 1 on the tailstock is adjusted first so that the turning tool 122 is in a horizontal state and the turning tool 122 is collinear with the diameter of the circular tube profile 2. At this time, the rotating rod 124 is located above the processing sleeve 121. By moving the tailstock, the turning tool 122 can be driven to cut the inner wall of the circular tube profile 2. After the tailstock drives the turning tool 122 out of the inside of the circular tube profile 2, the operator can rotate the rotating rod 124 to adjust the insertion depth of the turning tool 122, and then adjust the cutting amount of the turning tool 122 to process the inner wall of the circular tube profile 2 to the required size.

[0028] In an embodiment of the present utility model, a rotating head 1241 is provided at one end of the rotating rod 124 away from the adjusting rod 123, and the rotating head 1241 is flush with the circumferential surface of the fourth connecting end 1212, so that the operator can connect the rotating head 1241 with a wrench and drive the rotating rod 124 to rotate by rotating the wrench, thereby realizing the adjustment of the insertion depth of the turning tool 122 and the slot 1213.

[0029] In an embodiment of the present invention, the turning tool 122 is provided with scale lines along the length direction, so that the operator can adjust the insertion depth of the turning tool 122 and the slot 1213 according to the scale lines, thereby processing the inner wall of the round tube to the required size.

[0030] In an embodiment of the present utility model, when the turning tool 122 is inserted into the slot 1213, the height of the tip of the turning tool 122 is collinear with the diameter of the machining sleeve 121, so that the turning tool 122 is driven to contact the inner wall of the round tube profile 2 when the tailstock moves, and when the chuck drives the round tube profile 2 to rotate, it can be ensured that the turning tool 122 is always in contact with the inner wall of the round tube profile 2, thereby realizing the cutting processing of the round tube profile 2 by the turning tool 122.

[0031] In an embodiment of the present invention, the inner walls of the grooves of the second connecting end 112 and the fourth connecting end 1212 are both provided with internal threads, and the outer wall of the third connecting end 1211 is provided with external threads. The third connecting end 1211 is threadedly connected to the second connecting end 112 so that the processing sleeve 121 is connected to the connecting sleeve 11 and is relatively fixed. Therefore, after the connecting sleeve 11 is connected to the tail stock, the movement of the tail stock is controlled to drive the processing sleeve 121 to move synchronously, so that the turning tool 122 can realize cutting processing on the inner wall of the circular tube profile 2. The two processing sleeves 121 are threadedly connected to the fourth connecting end 1212 of the other connecting sleeve 11 through the third connecting end 1211 of one of the connecting sleeves 11, so that the two processing sleeves 121 are connected end to end and are relatively fixed, so that the two processing sleeves 121 can move synchronously with the tail stock, and the turning tools 122 on the two processing sleeves 121 can simultaneously process the inner wall of the circular tube profile 2, so as to realize rough processing and fine processing of the circular tube profile 2, thereby improving processing efficiency.

[0032] In an embodiment of the present utility model, the groove depth of the fourth connection end 1212 is equal to the length of the third connection end 1211, so that when the two processing sleeves 121 are plugged together end to end, the third connection end 1211 on one processing sleeve 121 can be inserted into the fourth connection end 1212 of the other processing sleeve 121, and the two processing sleeves 121 after plugging in can fit each other at the connection point, reducing the gap between the two after connection and improving the firmness and stability of the two processing sleeves 121 after connection.
