Existing polishing equipment requires the polishing disc to rotate on its own axis and swing around the metal sleeve being processed to ensure that the surface of the metal sleeve is treated. Therefore, existing polishing equipment needs to have three degrees of freedom motion control. Although the degree of freedom is relatively high, the transmission structure is relatively complex and the polishing efficiency is relatively low. Summary of the Invention

[0004] To achieve the above objectives, this application provides a metal sleeve surface polishing device: including a drive assembly, the output end of which is fixedly connected to a transmission disk, the transmission disk including a central column, and a plurality of equidistantly arranged adjustable suspensions rotatably connected to the outer side of the central column, the end of the central column having an adjustment disc, each of the adjustable suspensions being fixed relative to the adjustment disc by a limiting pin, the adjustment disc having a plurality of insertion holes equidistantly arranged around an axis, each adjustable suspension including a cross arm, the cross arm having a through groove, the limiting pin being adapted to pass through both the insertion hole and the through groove simultaneously, the end of the cross arm also being fixedly connected to a longitudinal arm, the lower end of the longitudinal arm being connected to a configuration disc, the configuration disc being fixedly connected to a polishing ring, the configuration disc and the polishing ring being suitable for having several models to adapt to metal sleeves of different sizes.

[0005] As a preferred embodiment, the configuration disk includes a positioning ring, the inner wall of which has a support ring, and the outer side of the polishing ring has a mating groove extending to the bottom surface, which is suitable for cooperating with the support ring. The polishing ring is fixedly connected to the support ring by a second bolt, so that the power of the configuration disk can be transmitted to the polishing ring.

[0006] As a preferred embodiment, the upper surface of the support ring has anti-rotation teeth between the inner wall of the positioning ring, and the polishing ring has a toothed groove on the inner top wall of the mating groove, which is suitable for mating with the anti-rotation teeth to share the shear stress on the second bolt and further improve the stability of the polishing ring relative to the mounting plate.

[0007] As a preferred embodiment, the supporting ring has a through hole that extends through the upper and lower surfaces, and the polishing ring has an internal threaded hole in the inner top wall of the mating groove. The second bolt passes through the through hole and engages with the internal threaded hole, and is fixed by tightening.

[0008] As a preferred embodiment, the outer surface of the positioning ring also has a collar, and the lower end of the longitudinal arm is fixedly connected to an inner bushing by a limiting ring, which is suitable for insertion into the collar. The inner bushing is threadedly connected to a first bolt, and the lower end of the first bolt with a larger size is suitable for constraining the collar outside the inner bushing to ensure the connection stability of the configuration plate at the lower end of the longitudinal arm.

[0009] As a preferred embodiment, the outer side of the center column has a hinge frame, the cross arm is rotatably connected to the hinge frame via a hinge shaft, the end of the cross arm away from the longitudinal arm has a shaft hole suitable for the hinge shaft to pass through, and a rib plate is also fixedly connected between the cross arm and the longitudinal arm to improve the structural strength of the entire adjustable suspension.

[0010] As a preferred embodiment, both ends of the central column are equipped with adjustment discs, and each adjustment disc is provided with a clearance hole at the end of each hinge shaft.

[0011] As a preferred embodiment, the drive assembly includes a mounting plate on which a motor and a reducer are fixedly connected. The output end of the reducer is fixedly connected to the transmission disk via a turntable, thereby realizing the transmission of power.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing an adjustable spacing suspension structure, it can be adapted to various models of configuration discs and polishing ring structures, and can handle multiple metal sleeves of different sizes. It takes into account flexibility, and the structure is less complex and the processing efficiency is higher.

[0014] (2) Since the configuration plate can install polishing rings on both the inner and outer sides, the equipment can treat both the outer and inner walls of the metal sleeve.

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8 The metal sleeve surface polishing equipment shown includes a drive assembly 1, which includes a horizontal mounting plate 101. The mounting plate 101 is fixedly connected to the frame structure. A motor 102 and a reducer 103 are also fixedly connected to the mounting plate 101. The output end of the motor 102 is connected to the input end of the reducer 103. A transmission disk 2 is fixedly connected to the output end of the drive assembly 1. In fact, the output end of the reducer 103 is fixedly connected to the transmission disk 2 through a turntable 104, thereby driving the transmission disk 2 to rotate.

[0029] The transmission disc 2 has a specific structure including a central column 201. Several adjustable suspensions 5 are rotatably connected to the outside of the central column 201. The adjustable suspensions 5 have a specific structure including a horizontal cross arm 510. In fact, the outer side of the central column 201 has several hinge frames 205 arranged equidistantly around the axis. The cross arm 510 is rotatably connected to the hinge frame 205 through the hinge shaft 3. One end of the cross arm 510 is also fixedly connected to a longitudinal arm 520. The end of the cross arm 510 away from the longitudinal arm 520 has a shaft hole 511, which is just enough for the hinge shaft 3 to pass through and cooperate with the hinge frame 205 to form a stable rotating pair.

[0030] The center column 201 has a multi-hole adjustable disc 202 at its end. Each adjustable suspension 5 is fixed relative to the adjustable disc 202 by a limiting pin 4. In fact, the adjustable disc 202 has several insertion holes 204 arranged equidistantly around the axis, and the cross arm 510 has an elongated through slot 512. The limiting pin 4 can pass through both the insertion holes 204 and the through slot 512 at the same time. In this embodiment, there are adjustable discs 202 at both ends of the center column 201. The two adjustable discs 202 are symmetrical about the center column 201. Each adjustable disc 202 has an opening at the end of each hinge shaft 3. There is a clearance hole 203 to facilitate the installation and removal of the hinge shaft 3. The limit pin 4 will pass through the through groove 512 from the upper insertion hole 204 and finally engage with the corresponding insertion hole 204 below. Since the inner wall width of the through groove 512 is the same as the diameter of the insertion hole 204, the limit pin 4 can effectively limit the movement of the cross arm 510 relative to the adjustment plate 202. The upper end of the limit pin 4 is also fixedly connected to the handle 402 by the retaining ring 401. The retaining ring 401 is used to limit the maximum sinking height of the limit pin 4 when it is engaged, and the handle 402 makes it convenient for the operator to pull the limit pin 4 upward.

[0031] A rib plate 503 is fixedly connected between the horizontal arm 510 and the vertical arm 520 to improve the connection strength between the horizontal arm 510 and the vertical arm 520. The lower ends of all the vertical arms 520 are connected to a configuration disk 6. The specific structure of the configuration disk 6 includes a positioning ring 601. The outer side of the positioning ring 601 also has a collar 605 extending radially outward. The lower end of the vertical arm 520 is fixedly connected to an inner bushing 522 through a limiting ring 521. The outer diameter of the inner bushing 522 is significantly smaller than the diameter of the limiting ring 521, and it is used to be inserted into the collar 605. The inner bushing 522 is threadedly connected to a first bolt 8. The larger lower end of the first bolt 8 just restrains the collar 605 outside the inner bushing 522, thereby maintaining the connection stability of the configuration disk 6 at the lower end of the vertical arm 520.

[0032] A polishing ring 7 is fixedly connected to the configuration plate 6. This ring is the main body that contacts the surface of the metal sleeve and performs polishing. The inner wall of the positioning ring 601 has a coaxial support ring 602. The outer side of the polishing ring 7 has a mating groove 701 extending to the bottom surface, which fits perfectly with the support ring 602. The polishing ring 7 needs to be fixedly connected to the support ring 602 by a second bolt 9. In order to achieve a tight connection, a through hole 604 penetrating the upper and lower surfaces needs to be opened on the support ring 602. The polishing ring 7 has an internal threaded hole on the inner top wall of the mating groove 701. 703. After the second bolt 9 passes through the through hole 604, it engages with the internal threaded hole 703. This allows the rotational power of the support ring 602 to be stably transmitted to the polishing ring 7. The upper surface of the support ring 602 and the inner wall of the positioning ring 601 have several anti-rotation teeth 603 arranged equidistantly around the axis. The polishing ring 7 has corresponding tooth grooves 702 on the inner top wall of the mating groove 701, which are used to engage with the anti-rotation teeth 603, thereby dispersing the shear stress on the second bolt 9 and ensuring the positional stability of the polishing ring 7 relative to the mounting plate 6.

[0033] Working principle: Both the mounting plate 6 and the polishing ring 7 can be of several different models. One mounting plate 6 can accommodate multiple polishing rings 7 with the same outer diameter but different inner diameters. Because the polishing rings 7 have different inner diameters and therefore different models, they can be machined with metal sleeves of different outer diameters. When the polishing rings 7 have different models due to different outer diameters, the corresponding mounting plate 6 needs to be replaced. At this point, all the limit pins 4 need to be removed, allowing each adjustable suspension 5 to move until all the inner bushings 522 simultaneously engage with the new mounting plate 6. The first bolt 8 is then used for securing. Finally, the limiting pin 4 is passed through the aligned insertion hole 204 and through groove 512. It should be noted that the polishing ring 7 that can cooperate with the new configuration plate 6 needs to be fixedly connected to the configuration plate 6 before the configuration plate 6 is connected to the longitudinal arm 520. For the configuration plate 6, the collar 605 may be located on the inner wall of the positioning ring 601, and the support ring 602 may be located on the outer wall of the positioning ring 601. At this time, the polishing ring 7 that cooperates with the configuration plate 6 can process the inner surface of the metal sleeve. Therefore, this polishing equipment has the function of processing both the inner and outer walls of the metal sleeve.
