[0001] The invention relates to the technical field of grinding, and in particular to a shaft annular grinding device. Background Art

[0002] In the machinery manufacturing industry, the accuracy and smoothness of shaft parts have a crucial impact on their performance and service life. Traditional shaft grinding methods are mostly manual or semi-automatic, which is not only inefficient, but also difficult to ensure the uniformity of grinding, especially when dealing with complex shapes and long shafts. In addition, traditional grinding methods are prone to unstable contact between the grinding belt and the shaft, which in turn affects the grinding effect and accuracy.

[0003] In order to overcome these shortcomings and improve the efficiency and quality of shaft grinding, there is an urgent need for a shaft annular grinding device with a high degree of automation and uniform grinding effect. Summary of the invention

[0026] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0027] Embodiment 1 like Figure 1-Figure 4 As shown, in this embodiment, a shaft annular grinding device is provided, comprising a housing 1 and a plurality of grinding wheels 2. A grinding channel for the shaft to move is provided in the middle of the housing 1. The grinding channel runs through both sides of the housing 1 and forms a through hole 101 on the outer wall of the housing 1. The two through holes 101 are arranged on the same straight line and opposite to each other. Such a design allows a shaft to smoothly enter the inner space of the housing 1 from one through hole 101, and then pass through and exit from the other through hole 101 without hindrance. In particular, the diameter of the through hole 101 is set to be larger than the diameter of the shaft, ensuring that the shaft can easily pass through the grinding channel during the crossing process, avoiding any possible obstruction or friction.

[0028] A plurality of grinding wheels 2 can move on a circular track. On the circular track, the plurality of grinding wheels 2 move synchronously, and their relative positions remain unchanged, that is, the distance between adjacent grinding wheels 2 is always kept constant during the movement. A grinding belt 3 is connected between two adjacent grinding wheels 2. When the grinding wheels 2 move along a predetermined path, the respective sleeved grinding belts 3 perform circular motion inside the grinding channel. These grinding belts 3 not only perform circumferential annular movement, closely fitting and surrounding the outside of the shaft, but also perform effective grinding operations on the outer surface of the shaft through their movement trajectories, thereby achieving smooth treatment of the outer surface. The grinding belt 3 has an overlapping portion with the grinding channel. When the shaft passes through the grinding channel, the grinding belt 3 is designed to have an overlapping portion with the channel and ensures that it is closely attached to the surface of the shaft. This design ensures that the grinding belt 3 can directly act on the outer surface of the shaft to achieve effective grinding and polishing effects.

[0029] In the process of the grinding wheel 2 rotating along the circular track, multiple grinding wheels 2 rotate on the circular track, and the speed and direction of the multiple grinding wheels 2 are the same, and the grinding belt 3 moves on the corresponding grinding wheel 2, that is, during the grinding process, the grinding wheel 2 revolves along the set circular track, and each grinding wheel 2 also keeps rotating. Since the distance between adjacent grinding wheels 2 is maintained constant, it is ensured that the grinding belt 3 sleeved between them will not be loose when the grinding wheel 2 moves. More importantly, when the grinding wheel 2 rotates, the grinding belt 3 is not only stably transmitted, but also increases the relative displacement with the surface of the shaft through this dynamic movement. This enhanced relative movement significantly improves the grinding effect, making the surface treatment of the shaft more refined and uniform.

[0030] A base is installed at the bottom of the shell 1, and an end cover is fixed on the upper end of the base. The base of the grinding device plays a role in firmly supporting the entire device, and an observation hole is carefully designed on the end cover. The main function of this observation hole is to facilitate the user to directly observe the real-time situation inside the shell 1 without opening the shell 1, so as to ensure clear and intuitive monitoring of the grinding process.

[0031] Embodiment 2 like Figure 1-Figure 7 As shown, based on the first embodiment, this embodiment provides a driving method of the grinding wheel 2, which is as follows: When there are multiple grinding wheels 2, the multiple grinding wheels 2 are evenly distributed on the circular track in the circumferential direction, and the outer annular surface of the grinding wheel 2 is provided with grooves 201 of the same number as the grinding wheel 2 along the axial direction, and the grinding belts 3 are connected in the corresponding grooves 201. The multiple grinding belts 3 are staggered and distributed, and the axis line of the grinding wheel 2 is kept parallel to the axis line of the grinding channel. This design ensures that when the grooves 201 are arranged along the axial direction of the grinding wheel 2, the grinding belts 3 installed in these grooves 201 will also be arranged one by one along the grinding channel. Therefore, when the shaft passes through the grinding channel and approaches the grinding wheel 2, it will contact each grinding belt 3 in turn, achieving a step-by-step and uniform grinding effect.

[0032] If the number of grinding wheels 2 exceeds three, they will form a closed polygonal structure inside the grinding channel. When the shaft passes through this polygonal area, its multiple surface areas will contact different grinding belts 3 in turn, thereby achieving multi-angle and all-round grinding. In this process, when the grinding belt 3 contacts the shaft, its side close to the shaft will produce adaptive deformation and fit closely to the surface of the shaft. This deformation not only increases the contact area between the grinding belt 3 and the shaft, but also improves the accuracy and efficiency of grinding.

[0033] There are three grinding wheels 2, and each grinding wheel 2 has three grooves 201. The grinding belts 3 connected between the three grinding wheels 2 can form a triangular grinding surface inside the grinding channel. On the cross section of the grinding channel, the three grinding belts 3 are precisely arranged to form an equilateral triangle structure. When the shaft passes through the triangular space formed by the grinding belts 3, each grinding belt 3 will be deformed due to the pressure of contact with the shaft, thereby changing from a straight line state to an arc shape that fits tightly on the surface of the shaft. This deformation ensures that the grinding belt 3 can fully contact the surface of the shaft to achieve a synchronous and uniform grinding effect.

[0034] It is worth noting that when the diameter of the shaft exceeds the radius of the circumscribed circle of the equilateral triangle, when inserting the shaft into the grinding belt 3, one of the grinding belts 3 can be pushed aside first, and then the shaft can be inserted into the three grinding belts 3, that is, the diameter of the shaft is large enough to contact and press the three grinding belts 3 at the same time, then on the cross section of the shaft, the contact area of ​​the three grinding belts 3 and the shaft will jointly form a complete circular area. This means that this area of ​​the shaft will be subjected to grinding from three directions at the same time, which helps to achieve a more comprehensive treatment effect.

[0035] The inside of the groove 201 is provided with an anti-skid tooth groove, and the inner annular surface of the grinding belt 3 is provided with anti-skid teeth adapted to the anti-skid tooth groove. During the grinding process of the shaft, the grinding belt 3 is closely attached to the surface of the shaft, and this close contact leads to a large friction between the two. In order to ensure the effective progress of the grinding operation and prevent slippage caused by insufficient friction, a high friction is also required between the grinding belt 3 and the grinding wheel 2 that drives it to rotate. In this way, even if the grinding belt 3 is subjected to a large friction between the shaft, it can still be firmly attached to the grinding wheel 2, especially avoiding slippage at the groove 201 of the grinding wheel 2, thereby ensuring the accuracy and efficiency of grinding.

[0036] Embodiment 3 like Figure 1-Figure 7 As shown, based on the first and second embodiments, this embodiment provides a self-rotation mode of the grinding wheel 2, which is as follows: The active disk 4 and the driven disk 5 are rotatably mounted on both sides of the inner part of the housing 1, and the central shaft 6 is fixed inside the grinding wheel 2. The two ends of the central shaft 6 are rotatably mounted on the active disk 4 and the driven disk 5, respectively. A driving mechanism for driving the active disk 4 to rotate is installed inside the housing 1, and the grinding wheel 2 is installed between the active disk 4 and the driven disk 5. The axes of these two disks coincide with the axis of the grinding channel. In this design, multiple grinding wheels 2 all perform circular motion along the axis direction of the grinding channel, and this motion is driven by the driving force of the active disk 4. At the same time, each grinding wheel 2 realizes flexible rotation between the active disk 4 and the driven disk 5 through a specific installation method, that is, the grinding wheel 2 can not only revolve around the axis of the grinding channel with the rotation of the active disk 4, but also realize self-rotation on its own axis. This dual rotation mechanism greatly enhances the grinding effect, so that the surface of the shaft can be processed more evenly and meticulously.

[0037] The driving mechanism includes a driving motor fixed on the housing 1, a driving gear 7 is fixed on the output shaft of the driving motor, and the active disk 4 is provided with teeth meshing with the driving gear 7. When the driving motor drives the driving gear 7 to rotate, the driving gear 7 further drives the active disk 4 to rotate, and the active disk 4 and the driven disk 5 will drive the grinding wheel 2 to rotate along the circular track.

[0038] A partition plate 9 is fixed inside the housing 1 , and the driving gear 7 and the active disk 4 are both rotatably mounted on the partition plate 9 .

[0039] A driven gear 10 is fixed to the end of the central shaft 6 away from the driven disc 5, and a gear ring 8 is fixed to the side wall of the housing 1. The driven gear 10 is meshed with the teeth on the gear ring 8. When the driving disc 4 and the driven disc 5 move along the circular track, they jointly pull the central shaft 6 to perform synchronous circular motion. In this process, the driven gear 10 firmly mounted on the central shaft 6 also moves along the circular path. As the driven gear 10 is tightly meshed with the teeth on the fixed gear ring 8, this interaction not only maintains the circular motion of the gear, but also causes the central shaft 6 to rotate. The rotation of the central shaft 6 further drives the grinding wheel 2 mounted thereon to rotate. While the grinding wheel 2 rotates, it drives the grinding belt 3 thereon to move smoothly along the surface of the shaft, thereby achieving fine grinding of the surface of the shaft. This process effectively combines circular motion and self-rotation motion, ensuring the efficiency and accuracy of the grinding operation.

[0040] Working principle: During operation, the shaft component needs to be inserted through the through hole 101 on the housing 1, and at the same time, the shaft passes through a set of carefully arranged grinding belts 3. These grinding belts 3 are tightly fitted to the surface of the shaft component and slightly deformed on both sides of the shaft component to adapt to its contour to ensure effective contact and grinding effect.

[0041] To achieve efficient grinding, a drive mechanism is integrated into the system, in which a drive motor is used as a power source, and the drive gear 7 rotates accordingly. This rotational action in turn drives the active disk 4 to rotate, and the active disk 4 is responsible for driving multiple grinding wheels 2 to perform circular motion in the housing 1. As the grinding wheels 2 move inside the housing 1, the driven gears 10 connected to each grinding wheel 2 also move accordingly. These driven gears 10 interact with the teeth on the gear ring 8 on the moving path, thereby causing the driven gears 10 to rotate.

[0042] The rotation of the driven gear 10 further drives the connected grinding wheels 2 to rotate, forming a grinding mechanism: the grinding belt 3 not only rotates around the shaft, but also slides and rubs on the surface of the shaft. This composite motion mode greatly enhances the uniformity and efficiency of grinding, ensuring that the surface of the shaft can be processed more finely and smoothly.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
