[0002] The thin cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in it. The working fluid converts thermal energy into mechanical energy through expansion in the engine cylinder, and the gas is compressed by the piston in the compressor cylinder to increase the pressure.

[0003] A Chinese patent discloses a cylinder liner inner hole honing device (authorization announcement number CN203236335U). This patented technology passes hydraulic oil into the thin-walled cylinder of the workpiece to hold the thin-walled cylinder tightly, which can better eliminate deformation during honing, effectively prevent deformation of the thin-walled cylinder, and greatly improve the honing accuracy.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during the processing of existing honing equipment, the opening angle of the honing head is often fixed. When facing cylinder liners with different apertures, if the opening angle of the honing head cannot match it, the corresponding honing head needs to be replaced, which not only increases the processing cost, but also reduces the processing efficiency. Utility Model Content

When facing cylinder liners with different apertures, if the opening angle of the honing head cannot match it, the corresponding honing head needs to be replaced, which not only increases the processing cost but also reduces the processing efficiency. For this reason, we propose a thin-wall cylinder liner inner hole honing auxiliary mechanism.

[0006] To achieve the above object, the present application adopts the following technical solution: A honing auxiliary mechanism for the inner hole of a thin-walled cylinder liner, including a connecting rod, one end of the connecting rod is fixedly connected with a disc, a circular hole is opened at one end of the disc, a regulating rod is rotatably connected inside the circular hole, one end of the regulating rod is fixedly connected with a first gear, six vertical grooves are opened at one end of the disc, a moving rod is slidably connected inside the vertical groove, an arc-shaped grinding plate is fixedly connected to the top of the moving rod, a second gear is meshed and connected to one side of the first gear, six arc-shaped grooves are opened at one end of the first gear, a circular rod is fixedly connected to one end of the moving rod, a through hole is opened at the other end of the disc, a movable rod is fixedly connected to the other end of the second gear, a notch is opened at the other end of the movable rod, a square block is slidably connected inside the notch, a handle is fixedly connected to one end of the square block, a plurality of tooth blocks are fixedly connected to the surface of the handle, a hollow block is fixedly connected to the other end of the disc, and a plurality of tooth grooves are opened inside the hollow block.

[0007] Preferably, guide grooves are opened on both sides of the inner cavity of the vertical groove, and guide blocks are fixedly connected to both sides of the moving rod.

[0008] Preferably, a circular limiting groove is opened in the inner cavity of the through hole, and a circular limiting ring block is fixedly connected to the surface height of the movable rod.

[0009] Preferably, a return spring is fixedly connected to one end of the square block, and one end of the return spring is fixedly connected to the inside of the notch.

[0010] Preferably, sliding grooves are opened on both sides of the inner cavity of the notch, and sliding blocks are opened on both sides of the square block.

[0011] Preferably, the external shape of the tooth block coincides with the internal shape of the tooth groove.

[0012] The technical effects and advantages of the present utility model:

[0013] In the present utility model, by rotating the movable rod, the movable rod drives the second gear to rotate, and then the first gear rotates.

[0021] Now, with reference to the accompanying drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0022] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the present utility model provides a technical solution: an auxiliary mechanism for honing the inner hole of a thin-walled cylinder liner, including a connecting rod 1. One end of the connecting rod 1 is fixedly connected to a disc 2. One end of the disc 2 is provided with a circular hole 3. Inside the circular hole 3, a regulating rod 4 is rotatably connected. One end of the regulating rod 4 is fixedly connected to a first gear 5. One end of the disc 2 is provided with six vertical slots 6. Inside the vertical slots 6, a moving rod 7 is slidably connected. The top of the moving rod 7 is fixedly connected to an arc-shaped grinding plate 8. One side of the first gear 5 is meshed with a second gear 11. One end of the first gear 5 is provided with six arc-shaped slots 9. One end of the moving rod 7 is fixedly connected to a circular rod 10. The other end of the disc 2 is provided with a through hole 12. The other end of the second gear 11 is fixedly connected to a movable rod 13. The other end of the movable rod 13 is provided with a notch 14. Inside the notch 14, a square block 15 is slidably connected. One end of the square block 15 is fixedly connected to a handle 16. The surface of the handle 16 is fixedly connected with a plurality of tooth blocks 17. The other end of the disc 2 is fixedly connected to a hollow block 18. Inside the hollow block 18, a plurality of tooth grooves 19 are provided. The staff rotates the movable rod 13, so that the movable rod 13 drives the second gear 11 to rotate, and then the first gear 5 rotates. Under the guidance of the arc-shaped slot 9, the circular rod 10 moves reciprocally along a certain track, further driving the moving rod 7 to slide in the vertical slot 6. Then the staff moves the handle 16, so that the handle 16 drives the tooth blocks 17 to insert into the inside of the hollow block 18 and abut against the tooth grooves 19, thereby completing the fixation of the position of the second gear 11, and thus realizing that the arc-shaped grinding plate 8 can adjust the opening angle to meet the honing requirements of the inner holes of cylinder liners with different diameters.

[0023] Referring to Figure 6 As shown in the figure, in this implementation: on both sides of the inner cavity of the vertical slot 6, guiding slots 25 are provided. On both sides of the moving rod 7, guiding blocks 26 are fixedly connected. By the cooperation of the guiding blocks 26 and the guiding slots 25, the movement track of the moving rod 7 when moving up and down inside the vertical slot 6 can be restricted, thereby avoiding the situation that the moving rod 7 moves too much and falls off from the inside of the vertical slot 6.

[0024] Referring to Figure 4 As shown in the figure, in this implementation: inside the inner cavity of the through hole 12, a circular limiting slot 20 is provided. On the surface of the movable rod 13, a circular limiting ring block 21 is fixedly connected. By the cooperation of the circular limiting slot 20 and the circular limiting ring block 21, when the movable rod 13 rotates inside the through hole 12, the circular limiting ring block 21 is always located inside the circular limiting slot 20, thus ensuring the stability of the movable rod 13 inside the through hole 12 and avoiding its shaking or deviation.

[0025] Referring to Figure 1As shown, in the present embodiment: one end of the square block 15 is fixedly connected to a return spring 22, and one end of the return spring 22 is fixedly connected to the inside of the slot 14. When the staff pulls the handle 16, the return spring 22 will start to accumulate force. When the staff releases the handle 16, the return spring 22 will drive the handle 16 to quickly return to its original position through its own force, making it faster for the staff to use it.

[0026] Reference Figure 4 As shown, in this embodiment: slide grooves 23 are provided on both sides of the inner cavity of the slot 14, and sliders 24 are provided on both sides of the square block 15. The sliders 24 are connected to the slide grooves 23 by sliding fit. This design makes the movement of the square block 15 in the slot 14 more stable and smooth, and at the same time, it can prevent the staff from escaping from the inside of the slot 14 when turning the handle 16 to drive the square block 15 to rotate.

[0027] Reference Figure 4 and Figure 5 As shown, in the present embodiment: the outer shape of the tooth block 17 matches the inner shape of the tooth groove 19. When the outer shape of the tooth block 17 matches the inner shape of the tooth groove 19, it can ensure that the tooth block 17 can be inserted into the tooth groove 19 more tightly without shaking, thereby improving the stability of the structure.

[0028] Working principle: The operator rotates the movable rod 13, which drives the second gear 11 to rotate, and then makes the first gear 5 rotate. The circular rod 10 moves reciprocally along a certain trajectory under the guidance of the arc-shaped groove 9, further driving the movable rod 7 to slide in the vertical groove 6. Subsequently, the operator moves the handle 16, which drives the tooth block 17 to insert into the interior of the hollow block 18 and abut against the tooth groove 19, thereby fixing the position of the second gear 11, so as to realize that the arc-shaped grinding plate 8 can adjust the opening angle to meet the honing requirements of the inner holes of cylinder liners with different diameters. By using the cooperation of the guide block 26 and the guide groove 25, the movement trajectory of the movable rod 7 when moving up and down inside the vertical groove 6 can be restricted, thus avoiding the situation that the movable rod 7 moves too much and falls off from the interior of the vertical groove 6. By using the cooperation of the circular limit groove 20 and the circular limit ring block 21, when the movable rod 13 rotates inside the through hole 12, the circular limit ring block 21 is always located inside the circular limit groove 20, thereby ensuring the stability of the movable rod 13 inside the through hole 12 and avoiding its shaking or deviation. By using the cooperation of the circular limit groove 20 and the circular limit ring block 21, when the movable rod 13 rotates inside the through hole 12, the circular limit ring block 21 is always located inside the circular limit groove 20, thereby ensuring the stability of the movable rod 13 inside the through hole 12 and avoiding its shaking or deviation. The slider 24 and the sliding groove 23 are connected by a sliding fit. This design makes the movement of the square block 15 in the notch 14 more stable and smooth. At the same time, it can also prevent the operator from detaching from the interior of the notch 14 when rotating the handle 16 to drive the square block 15 to rotate. When the external shape of the tooth block 17 matches the internal shape of the tooth groove 19, it can ensure that the tooth block 17 is more tightly inserted into the interior of the tooth groove 19 without shaking, improving the stability of the structure.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
