Auxiliary device for magnetic core processing

Abstract

The utility model relates to an auxiliary device for processing a magnetic core. The auxiliary device structurally comprises two follow-up shafts, wherein driven shafts are respectively mounted at the axial end parts of the follow-up shafts. One side of the follow-up shaft is connected with a driving motor through a transmission device and serves as a power source. And a positioning ring is arranged between the two follow-up shafts. The near ends of the two follow-up shafts are connected with the transmission shaft through keys, and the far ends of the two follow-up shafts are connected with the follow-up bevel gears through keys. In addition, transmission rings are arranged at the two ends of the positioning ring respectively, and the inner diameter of each transmission ring is larger than the outer diameter of the transmission shaft. Therefore, when the transmission ring is sleeved on the outer side of any transmission shaft, the key connection between the transmission shaft and the transmission ring can drive the driven shaft to rotate. Meanwhile, one sides of the two follow-up bevel gears are connected with the driving bevel gear through common meshing, and therefore reverse rotation of the two driven shafts is achieved. According to the design, under the condition that the magnetic core is movably connected with the single driven shaft, the rotating direction of the magnetic core can be changed by adjusting the position of the positioning ring.

DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] Please refer to Figure 1 、 Figure 2 The invention relates to an auxiliary device for magnetic core processing, which has the same structure as the similar devices in the prior art. The main structure of the device comprises a base plate 4, the upper area of ​​which is equipped with a driving motor 1 and a follower shaft 3.

[0024] The output shaft of the driving motor 1 is connected to the follower shaft 3 via a set of precision gear sets 2, thereby ensuring the high efficiency and stability of power transmission.

[0025] Compared with the prior art device, the present device is additionally provided with two driven shafts 6 , which are sleeved on the outside of the follower shaft 3 and realize a coaxial rotation connection with the follower shaft 3 .

[0026] It should be emphasized that, in actual applications, due to the presence of two driven shafts 6, which are arranged in parallel along the central axis of the follower shaft 3 and form a transmission connection with the follower shaft 3, in practice, one of the driven shafts 6 located relatively far from the drive motor 1 can be set as the drive shaft 5. A corresponding clamping mechanism (not shown) is installed on this driven shaft 6. After the magnetic core is clamped and fixed, the magnetic core can be rotated by rotating this driven shaft 6.

[0027] Furthermore, it should be noted that the outer side of each driven shaft 6 is rotationally connected to a support frame via a bearing, and the support frame is fixedly connected to the base plate 4. On this basis, if the driven shaft 6 and the follower shaft 3 are further rotationally connected via bearings, the support frame can simultaneously secure the position of the driven shaft 6 while simultaneously ensuring the stability of the follower shaft 3, thereby ensuring the stability of the connection between the follower shaft 3, the gear set 2, and the drive motor 1.

[0028] Specifically, if Figure 2 and Figure 3 As shown, to achieve a transmission connection between the follower shaft 3 and the driven shaft 6, this device is equipped with a locating ring 11 between the two driven shafts 6. This locating ring 11 is mounted on the outside of the follower shaft 3 and secured to the follower shaft 3 via a key connection. This further restricts the sliding connection between the locating ring 11 and the follower shaft 3, allowing the locating ring 11 to move linearly along the central axis of the follower shaft 3.

[0029] Meanwhile, the two driven shafts 6 are each fitted with a transmission shaft 8 through key connection at a position close to the end thereof. In addition, the two axial end portions of the positioning ring 11 are each coaxially fixedly connected with a transmission ring 9. Therefore, by designing the inner diameter length of the transmission ring 9 to be greater than the outer diameter length of the transmission shaft 8, the nested configuration between the transmission ring 9 and the transmission shaft 8 is achieved.

[0030] On this basis, further constraint is made on the transmission ring 9 to be connected with the transmission shaft 8 on the same side through key connection when the positioning ring 11 and the driven shaft 6 on the same side are in the same vertical plane, i.e. the nested configuration between the transmission ring 9 and the transmission shaft 8. Thus, by the cooperation of the positioning ring 11 and the transmission ring 9, the rotational driving of the driven shaft 6 and the transmission shaft 8 is achieved.

[0031] Further, in order to realize the rotation of the magnetic core in different directions, the device adopts a key connection mode to install a driven bevel gear 7 at the end away from the two driven shafts 6. And, a driven bevel gear 10 is configured on one side of the two driven bevel gears 7, which is connected with the driven bevel gear 7 through meshing transmission, so as to realize accurate power transmission.

[0032] It needs to be made clear that, in actual application, as shown in Figure 1 the design of the device is to drive the magnetic core to rotate by connecting the driven shaft 6 close to the rear end with the clamping mechanism. Specifically, when the transmission ring 9 close to the rear end is sleeved on the transmission shaft 8 on the same side, the driven shaft 6 on the rear side will be directly driven to rotate by the driven shaft 3; while when the transmission ring 9 close to the front end is sleeved on the transmission shaft 8 on the same side, the driven shaft 6 on the rear side will be driven to reverse by the driven bevel gear 10 through the driven bevel gear 7 on the front side.

[0033] Further, the design of the device ensures that the distance between the ends away from the two transmission rings 9 is greater than the distance between the ends close to the two transmission shafts 8. This design aims to ensure that the two transmission rings 9 can only be nested with a single transmission shaft 8 respectively, effectively preventing the transmission ring 9 from being nested with two transmission shafts 8 at the same time, so as to avoid the problem of stroke conflict.

[0034] Further, the device designs the projection of each transmission shaft 8 in the vertical plane as a trapezoidal structure, specifically, the diameter of the end of the transmission shaft 8 close to the positioning ring 11 is smaller than the diameter of the end away from the positioning ring 11, so as to optimize the nested cooperation between the transmission shaft 8 and the transmission ring 9.

[0035] The specific structure is shown in Figure 2 , Figure 5As shown, each transmission shaft 8 is provided with a connecting key 16, and the inner side of each transmission ring 9 is provided with a corresponding matching groove 15 for the connecting key 16. When the connecting key 16 is completely embedded in the matching groove 15, the key connection between the transmission shaft 8 and the transmission ring 9 is formed.

[0036] Therefore, in order to effectively avoid the problem of reduced nesting success rate caused by the mismatch between the matching groove 15 and the connecting key 16 during the nesting process of the transmission shaft 8 and the transmission ring 9, the number of connecting keys 16 is set to multiple, and these connecting keys 16 are equally distributed around the central axis of the transmission shaft 8.

[0037] Furthermore, the device also provides that the projection of each connecting key 16 in the vertical plane presents a trapezoidal structure. Specifically, the width and height of the connecting key 16 near one end of the positioning ring 11 are smaller than those away from the other end of the positioning ring 11. This design aims to further improve the nesting success rate between the connecting key 16 and the matching groove 15.

[0038] Specifically, as shown in Figure 2 , Figure 4 In order to achieve precise control of the position of the positioning ring 11, the device adds a driving ring 12 outside the positioning ring 11. In this process, by ensuring that the inner diameter of the driving ring 12 is smaller than the outer diameter of the transmission ring 9, the effective linkage between the driving ring 12 and the positioning ring 11 is ensured, and in turn, when the driving ring 12 moves, it can drive the positioning ring 11 to move synchronously.

[0039] Therefore, on one side of the driving ring 12, we set a driving shaft 5, the central axis of which is perpendicular to the central axis of the driving ring 12. At the same time, the driving shaft 5 is rotationally connected to the driving ring 12 through an up-down axial pivot. This enables the device to drive the driving ring 12 by rotating the driving shaft 5, thereby achieving adjustment of the position of the positioning ring 11.

[0040] Specifically, a through groove 14 is vertically and axially provided in the middle section of the driving shaft 5, and a positioning shaft 13 is inserted into the through groove 14.

[0041] Furthermore, the device constrains the length of the through groove 14 to be greater than the diameter of the positioning shaft 13. This design aims to ensure the stability and accuracy of the positioning shaft 13, thereby effectively avoiding the stroke conflict between the driving shaft 5 and the positioning shaft 13.

[0042] Furthermore, the device also constrains the length between the end of the driving shaft 5 away from the follower shaft 3 and the positioning shaft 13 to be greater than the distance between the end near the follower shaft 3 and the positioning shaft 13. This design ensures that users can more conveniently and labor-savingly rotate the driving shaft 5.

[0043] In actual application scenarios, the operation process of the utility model is as follows:

[0044] Firstly, the special clamping mechanism is used to ensure that the device and the magnetic core are connected stably.

[0045] Then, the driving motor 1 is started.

[0046] Then, the operator needs to hold the driving shaft 5 and rotate it around the positioning shaft 13.

[0047] Finally, when the magnetic core needs to be reversed, the operator needs to rotate the driving shaft 5 in the opposite direction, so that the other transmission ring 9 is sleeved outside the corresponding transmission shaft 8, thereby driving the magnetic core to reverse.

[0048] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
