DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0030] Reference Figure 1 , Figure 2 and Figure 4, an embodiment of the utility model: a diameter adjustment mold for bearing processing, comprising a workbench 1 and an arc-shaped bar 17, open grooves 3 are provided on the left and right sides of the top of the workbench 1, and the left and right sides of the workbench 1 are rotatably connected with first screw rods 4, and the adjacent ends of the two first screw rods 4 respectively penetrate the corresponding open grooves 3, and the outer side of the first screw rods 4 is threadedly connected with a first movable block 5, and the top of the left first movable block 5 is fixedly connected with a U-shaped plate 6, and the top of the U-shaped plate 6 is fixedly connected with a servo motor 7, and the output end of the servo motor 7 penetrates the U-shaped plate 6 and is fixedly connected with a driving gear 8, and the inner bottom right end of the U-shaped plate 6 is rotatably connected with a disk 9, and the top of the disk 9 is fixedly connected with a driven hollow gear 10, and the driven hollow gear 10 is meshed with the driving gear 8. A plurality of connecting rods 11 are fixedly connected to the inner side of the driven hollow gear 10 at equal intervals, and one end of the plurality of connecting rods 11 is fixedly connected with the same limiting ring 12, and the top of the limiting ring 12 is equidistantly rotated around. A plurality of first rotating shafts 13 are rotatably connected, one end of each of the plurality of first rotating shafts 13 respectively passes through the limiting ring 12 and is fixedly connected with an arc plate 14, a second rotating shaft 15 is rotatably connected to one side of the top of the arc plate 14, a plurality of third rotating shafts 16 are rotatably connected to the top of the driven hollow gear 10 at equal intervals, and the plurality of third rotating shafts 16 are respectively connected to the corresponding second rotating shafts 15 through arc bars 17, a placement plate 18 is fixedly connected to the top of the first movable block 5 on the right side, a fixed column 19 is fixedly connected to the middle of the top of the placement plate 18, a plurality of cylinders 20 are fixedly connected to the outer sides of the fixed column 19 at equal intervals, and an arc support plate 21 is fixedly connected to the output end of the cylinder 20, a hollow plate 26 is provided on the upper side of the workbench 1, a second movable block 28 is slidably connected to the inside of the hollow plate 26, a hollow rod 29 is fixedly connected to the bottom of the second movable block 28, a disassembly mechanism 2 is provided at the bottom of the hollow rod 29, and the two first movable blocks 5 are slidably connected to the inside of the corresponding opening groove 3 respectively;

[0031] Specifically, when the outer diameter of the bearing needs to be calibrated, the bearing to be processed is first placed on the placement plate 18, and then the cylinder 20 can drive the surrounding arc-shaped support plates 21 to move outward to limit and clamp the bearing, ensuring the stability of the bearing during the calibrating process. Next, the hydraulic rod 23 will drive the hollow plate 26 to move downward until the calibrating head 207 contacts the bearing, and finally the servo motor 25 can drive the hollow plate 26 to rotate, thereby completing the calibrating work of the outer diameter of the bearing. When the inner diameter of the bearing needs to be calibrated, the servo motor 7 can drive the driving gear 8 to start rotating. Due to the meshing with the driving gear 8, the driven hollow gear 10 will also rotate. At this time, the first rotating shaft 13 and the third rotating shaft 16 on the driven hollow gear 10 will drive the surrounding arc-shaped plates 14 to merge in the middle to limit and fix the bearing. Under the premise of ensuring that the bearing is stable and fixed, repeat the above calibrating steps to easily complete the calibrating work of the inner diameter of the bearing. The biggest advantage of this new calibrating device is that it can handle bearings of different sizes without replacing different devices. This not only greatly reduces the complexity of the operating process, but also significantly improves the processing efficiency of the bearings.

[0032] Reference Figure 1 and Figure 3 The disassembly mechanism 2 includes a movable rod 201, which is slidably connected to the inside of the hollow rod 29. Holes 202 are provided on the left and right sides of the movable rod 201. A spring 203 is fixedly connected to one side of the inside of the hole 202. One end of the spring 203 is fixedly connected to a limiting rod 204. Limiting holes 205 are provided on the left and right sides of the hollow rod 29. One end of the two limiting rods 204 passes through the corresponding limiting holes 205 respectively. An L-shaped rod 206 is fixedly connected to the bottom end of the movable rod 201. A calibrating head 207 is fixedly connected to the left end of the L-shaped rod 206. The sizes of the two limiting rods 204 match the sizes of the corresponding internal sizes of the holes 202 respectively.

[0033] Specifically, when the calibrating head 207 is damaged after long-term use, it is only necessary to press the limiting rods 204 on both sides. This action will cause the spring 203 to be squeezed, thereby driving the limiting rod 204 to disengage from the limiting hole 205 and smoothly enter the hole 202. At this time, the entire calibrating head 207 is already in a detachable state. The operator only needs to continue to move the movable rod 201 downward to easily remove the calibrating head 207. This design not only simplifies the replacement process of the calibrating head 207, but also greatly improves the practicality of the device.

[0034] Reference Figure 1 and Figure 2The top rear side of the workbench 1 is fixedly connected with an L-shaped plate 22, the inner top of the L-shaped plate 22 is fixedly connected with a hydraulic rod 23, the output end of the hydraulic rod 23 is fixedly connected with a hollow frame 24, the inner top of the hollow frame 24 is fixedly connected with a servo motor 25, the output end of the servo motor 25 is fixedly connected with the top right side of the hollow plate 26, the left side of the hollow plate 26 is rotatably connected with a second screw rod 27, the right end of the second screw rod 27 penetrates the hollow plate 26, and the second movable block 28 is threadedly connected with the outer side of the second screw rod 27;

[0035] Specifically, the hollow plate 26 can be driven downward by the hydraulic rod 23, and the second movable block 28 can be driven left and right by rotating the second screw rod 27, so that the position of the calibrating head 207 can be easily adjusted, and bearings of different sizes can be processed.

[0036] Reference Figure 1 A controller 30 is fixedly connected to the front right side of the top of the workbench 1. The controller 30 is electrically connected to the servo motor 7, the cylinder 20, the hydraulic rod 23 and the servo motor 25 respectively. A protective cover 31 is arranged on the outside of the controller 30. One side of the protective cover 31 is rotatably connected to the top of the workbench 1.

[0037] Specifically, the controller 30 can control the operation of the servo motor 7, the cylinder 20, the hydraulic rod 23 and the servo motor 25, and the protective cover 31 can protect the controller 30 from being damaged by external factors.

[0038] Working principle: When it is necessary to perform sizing work on the outer diameter of the bearing, first rotate the first screw rod 4 on the left to drive the U-shaped plate 6 to move to the right until the placement disk 18 is completely exposed, and then rotate the first screw rod 4 on the right to move the placement disk 18 to the middle position of the top of the workbench 1. At this time, place the bearing to be processed on the placement disk 18, and then use the cylinder 20 to drive the surrounding arc-shaped support plates 21 to move outward to limit the bearing. Then, the hydraulic rod 23 can drive the hollow plate 26 to move downward until the sizing head 207 contacts the bearing, and the second screw rod 27 can be rotated to adjust the position of the sizing head 207, so that it can adapt to bearings of different sizes. At this time, the servo motor 25 drives the hollow plate 26 to rotate to perform sizing work. When it is necessary to perform sizing work on the inner diameter of the bearing, first rotate the first screw rod 4 on the left to move the driven hollow gear 10 on the U-shaped plate 6 to the middle position of the top of the workbench 1. , then the servo motor 7 can drive the driving gear 8 to rotate, and the driven hollow gear 10 will rotate accordingly due to the meshing with the driving gear 8. At this time, the first rotating shaft 13 and the third rotating shaft 16 on the driven hollow gear 10 will rotate accordingly, so as to drive the arc plates 14 around to merge to the middle to limit and fix the bearing, and then repeat the above-mentioned diameter adjustment work. The outer diameter and inner diameter of the bearing can be diameter adjusted without replacing different devices, thereby reducing the operation process and improving the processing efficiency of the bearing, which can meet the needs of users. When the diameter adjustment head 207 is damaged after long-term use, the limit rods 204 on both sides are pressed at this time, and the extrusion force of the spring 203 will drive the limit rod 204 to disengage from the limit hole 205 and enter the hole 202. At this time, the movable rod 201 can be moved downward to remove the diameter adjustment head 207. It is relatively simple to disassemble and replace the diameter adjustment head 207, thereby improving the practicality of the device.
