Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a sleeve rotation device. Background Technology

[0002] After the battery or capacitor is manufactured, a plastic sleeve with positive and negative markings and manufacturer information printed on it needs to be fitted onto the outer periphery of the casing. Figure 1 As shown, the existing sleeve assembly device requires rotation to achieve sleeve handling. Its specific rotation structure is that the rotating shaft is directly connected to the rotating seat, so the rotating shaft directly drives the rotating seat to rotate. If the rotating seat encounters foreign object collisions or interference during the rotation process, it cannot rotate to the set position, but the rotating shaft is always under force. This excessive torque makes the rotating shaft, rotating seat and other components easy to be damaged. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a sleeve rotation device that can prevent damage to components from excessive torque. The specific technical solution is as follows:

[0004] A sleeve rotation device includes a rotating base, a sleeve-retrieving mechanism, a bearing, a rotating shaft, a torque adjusting nut, an elastic element, a pressure plate, steel balls, a chuck, and a positioning plate. The sleeve-retrieving mechanism is installed on the rotating base. A bearing is installed at the center of the rotating base. The rotating shaft is movably mounted inside the bearing. The rotating shaft passes through the positioning plate, chuck, and pressure plate sequentially from bottom to top. The upper end of the rotating shaft is threaded to the torque adjusting nut. The elastic element is located between the torque adjusting nut and the pressure plate. The torque adjusting nut drives the pressure plate to press down on the steel balls through the elastic element. The chuck has multiple spaced slots, and the positioning plate has multiple spaced positioning grooves. The positioning plate is fixedly installed on the rotating base, and the steel balls are located in the slots and positioning grooves.

[0005] As a preferred embodiment of this utility model, the positions and quantities of the card slot and the positioning slot correspond, and one steel ball is installed in each card slot and each positioning slot.

[0006] As a preferred embodiment of this utility model, the slot is a through slot and the positioning slot is a blind hole arc-shaped slot. The slot contacts the middle of the steel ball and the positioning slot contacts the bottom of the steel ball, so that the steel ball can be detached from the positioning slot.

[0007] As a preferred embodiment of this utility model, the spacing between the card slots is not equal.

[0008] As a preferred embodiment of this utility model, when the torque is too high, the steel ball disengages from the positioning groove, and the chuck and positioning plate rotate relative to each other.

[0009] In a preferred embodiment of this utility model, the elastic element is a tension spring.

[0010] In a preferred embodiment of this invention, the rotating shaft is driven to rotate by a cam divider below.

[0011] As a preferred embodiment of this utility model, the rotating shaft is composed of an upper shaft part and a lower shaft part connected as one piece. The outer diameter of the upper shaft part is smaller than that of the lower shaft part. There are two bearings. The lower shaft part carries the lower bearing. The lower bearing is placed in the lower part of the rotating seat, and the upper bearing is placed in the upper part of the rotating seat. The upper shaft part passes through the two bearings in sequence upwards.

[0012] Beneficial effects: Compared with the prior art, the main improvement of this utility model sleeve rotation device is the connection structure between the rotating shaft and the rotating seat. By adding a torque adjusting nut, elastic element, pressure plate, steel ball, chuck and positioning plate, the rotating shaft rotates the rotating seat in sequence through the torque adjusting nut, elastic element, pressure plate, steel ball and positioning plate during normal use. When the torque is too large, the friction between the steel ball and the positioning groove is insufficient to make the positioning plate rotate, and the steel ball disengages from the positioning groove. In this way, the rotation of the rotating shaft will not cause the rotating seat to rotate, thus achieving the purpose of protecting the rotating seat. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 2-5 As shown, a sleeve rotation device includes a rotating base 1, a sleeve-retrieving mechanism 2, a bearing, a rotating shaft 4, a torque adjusting nut 5, an elastic element 6, a pressure plate 7, a steel ball 8, a chuck 9, and a positioning plate 10. The sleeve-retrieving mechanism 2 is installed on the rotating base 1. The sleeve-retrieving mechanism 2 has two parts, which are existing technologies mainly used for retrieving empty sleeves and can be pneumatic fingers, suction heads, etc. The bearing is installed at the center of the rotating base 1. The rotating shaft 4 is movably mounted inside the bearing. The rotating shaft 4 passes through the positioning plate 10, the chuck 9, and the pressure plate 7 from bottom to top. The upper end of the rotating shaft 4 is threaded to the torque adjusting nut 5. The elastic element 6 is located between the torque adjusting nut 5 and the pressure plate 7. The torque adjusting nut 5 drives the pressure plate 7 to press down on the steel ball 8 through the elastic element 6. The chuck 9 has multiple spaced slots 91, and the positioning plate 10 has multiple spaced positioning grooves 101. The positioning plate 10 is fixedly installed at the center of the rotating base 1 by screws. The steel ball 8 is located in the slots 91 and the positioning grooves 101.

[0022] like Figure 3 and 4 As shown, the positions and numbers of the slots 91 and 101 correspond. One steel ball 8 is installed in each slot 91 and each 101. The slot 91 is a through slot, and the 101 is a blind hole arc-shaped slot. The slot 91 contacts the middle of the steel ball 8, and the 101 contacts the bottom of the steel ball 8. When the rotating seat 1 cannot rotate, the rotating shaft can make the steel ball 8 disengage from the 101.

[0023] Specifically, the spacing between the slots 91 is unequal, meaning the distance between two adjacent slots 91 is not equal to the distance between two other adjacent slots 91. This is done so that the steel ball 8 can only reset when it rotates one full revolution back to its initial position. When the rotating seat 1 is subjected to excessive torque, the steel ball 8 disengages from the positioning slot 101, and the chuck 9 and the positioning plate 10 rotate relative to each other, thus protecting the rotating seat 1.

[0024] Specifically, the elastic element 6 is a tension spring, and the rotating shaft 4 is driven to rotate by the lower cam divider 11. In addition, the rotating shaft 4 is composed of an upper shaft part 41 and a lower shaft part 42 connected as one piece. The outer diameter of the upper shaft part 41 is smaller than that of the lower shaft part 42. There are two bearings 3. The lower shaft part 41 carries the lower bearing 3. The lower bearing 3 is placed in the lower part of the rotating seat 1, and the upper bearing 3 is placed in the upper part of the rotating seat 1. The upper shaft part 41 passes through the two bearings 3 in sequence.

[0025] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
