Furthermore, the required roughness of the inner and outer walls may differ depending on the needs. Therefore, in addition to meeting the requirement of grinding both the inner and outer walls simultaneously, it is also necessary to be able to grind the inner or outer wall separately. Utility Model Content

[0011] Beneficial effects

[0012] This utility model provides a grinding device for the inner and outer walls of a spacer sleeve, which has the following beneficial effects:

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Wherein, directional terms such as "upper" and "lower" mentioned herein are used in conjunction with... Figure 1 The orientation is used as a reference.

[0019] Please see Figure 1-2 This utility model provides a technical solution: a grinding device for the inner and outer walls of a spacer sleeve, including a base plate 1; a gantry frame 2 is fixedly installed on the base plate 1, a mounting box 5 is rotatably installed on the top of the gantry frame 2, a gearbox 4 is fixedly installed on the bottom of the mounting box 5, a through hole 19 is opened in the mounting box 5 and the gearbox 4, a movable box 9 is movably installed in the through hole 19, a second motor 10 is fixedly installed in the movable box 9, a gear 11 is rotatably installed in the gearbox 4, the drive end of the second motor 10 is fixedly connected to the gear 11, an inner gear ring 13 and an outer gear ring 12 that mesh with the gear 11 are rotatably installed in the gearbox 4, a pair of concentric annular grooves 17 with different radii are opened at the bottom of the gearbox 4, grinding rollers 14 are fixedly installed at the bottom of both the inner gear ring 13 and the outer gear ring 12, and a pair of grinding rollers 14 are slidably installed in a pair of annular grooves 17; a fixing component for fixing the spacer sleeve 826 is installed on the base plate 1, and the mounting box 5 is rotatably installed. The rotation of the mounting box 5 drives the gearbox 4 to rotate, which in turn drives a pair of grinding rollers 14 to rotate, thus enabling simultaneous grinding of the inner and outer walls of the spacer sleeve 826. A movable box 9 is movably mounted, and its movement drives the second motor 10 and gear 11 to move together, thereby controlling the engagement of gear 11 with the inner gear ring 13 or with the outer gear ring 12. The gearbox 4 is used to mount gear 11 and the gear ring. Rotating gear 11 causes it to mesh with the inner gear ring 13, which in turn drives the grinding rollers 14 fixed on the inner gear ring 13 to rotate, thus enabling separate grinding of the outer wall of the spacer sleeve 826. Similarly, the engagement of gear 11 with the outer gear ring 12 causes the outer gear ring 12 to rotate, which in turn drives the grinding rollers 14 fixed on the outer gear ring 12 to rotate, thus enabling separate grinding of the inner wall of the spacer sleeve 826.

[0020] Furthermore, a second cylinder 8 is fixedly installed on the side wall of the mounting box 5. The telescopic end of the second cylinder 8 is fixedly connected to the movable box 9. By installing the second cylinder 8, starting the second cylinder 8 and extending or retracting the telescopic end of the second cylinder 8 can drive the movable box 9 to move.

[0021] Furthermore, the fixing component includes an annular electromagnet 16, and a base 15 is fixedly installed on the base plate 1. The annular electromagnet 16 is set on the base 15. By setting the annular electromagnet 16, the annular electromagnet 16 can generate magnetic force after being energized, thereby fixing the spacer sleeve 826, thus avoiding the spacer sleeve 826 from moving and making it inconvenient to grind when grinding.

[0022] Furthermore, a motor housing 3 is movably installed on the top of the portal frame 2. A first motor 7 is fixedly installed inside the motor housing 3. The drive end of the first motor 7 passes through the bottom wall of the motor housing 3 and is fixedly connected to the mounting box 5. By installing the motor housing 3, the motor can be installed. The movement of the motor housing 3 can drive the mounting box 5, the gearbox 4, and the grinding roller 14 to move, so that the grinding roller 14 can move to contact the spacer sleeve 826, so as to grind the spacer sleeve 826.

[0023] Furthermore, a first cylinder 6 is fixedly installed at the top of the portal frame 2. The telescopic end of the first cylinder 6 passes through the top wall of the portal frame 2 and is fixedly connected to the motor box 3. By installing the first cylinder 6, starting the first cylinder 6 can drive the motor box 3 to rise and fall by extending and retracting the telescopic end of the first cylinder 6.

[0024] Furthermore, a pair of guide rods 20 are slidably installed on the top wall of the portal frame 2. The bottom of the pair of guide rods 20 is fixedly connected to the motor housing 3. By installing the guide rods 20, the motor housing 3, the mounting box 5 and the gear box 4 can be guided, making their lifting and lowering more stable.

[0025] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0026] The working principle and usage process of this utility model are as follows: In use, the annular electromagnet 16 is energized, and the spacer sleeve 826 is placed on the annular electromagnet 16 and fixed. The first cylinder 6 is started, driving the motor housing 3, mounting housing 5, and gearbox 4 to descend until the pair of grinding rollers 14 contact the inner and outer walls of the spacer sleeve 826. When it is necessary to grind the inner and outer walls of the spacer sleeve 826 simultaneously, the first motor 7 is started, driving the mounting housing 5 and gearbox 4 to rotate together, thereby driving the pair of grinding rollers 14 to rotate together, thus simultaneously grinding the inner and outer walls of the spacer sleeve 826. When it is necessary to grind the spacer sleeve alone... When grinding the inner or outer wall of spacer 826, the second cylinder 8 is started to move the moving box 9, which in turn moves the gear 11. At the same time, the second motor 10 is started to rotate the gear 11. When the gear 11 moves to mesh with the inner gear ring 13, it can drive the inner gear ring 13 to rotate, which in turn drives the grinding roller 14 on the inner gear ring 13 to rotate. This can achieve grinding of the outer wall of spacer 826 alone. When the second cylinder 8 drives the gear 11 to mesh with the outer gear ring 12, the outer gear ring 12 rotates, which can drive the grinding roller 14 on the outer gear ring 12 to rotate, thus achieving grinding of the inner wall of spacer 826 alone.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
