Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The first embodiment of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, a rail chamfering device that can be installed quickly is provided, including a three-bladed chamfering cutter 1 and two nuts 2;

[0029] Two nuts 2 are welded together on the top and bottom of the same axis. The bottom end of the three-bladed chamfering cutter 1 is inserted into the middle through hole of the two nuts 2 in sequence. The axis of the three-bladed chamfering cutter 1 coincides with that of the two nuts 2. The three-bladed chamfering cutter 1 is fixed to the two nuts 2 respectively.

[0030] Nut 2 has a diameter of 36mm, which makes it easy and quick to install on the 36mm socket wrench of the lithium battery wrench.

[0031] In this embodiment, the 36mm socket wrench of the lithium battery wrench is aligned with the two welded nuts 2 at the tail of the embodiment. The socket wrench is then inserted into the nuts 2 until they are fully fitted. The lithium battery wrench is then activated, and the torque of the lithium battery wrench is used to fix the embodiment onto the socket wrench, ensuring a stable connection. The three-blade chamfering cutter 1 removes the chamfer around the bolt hole under the power drive of the lithium battery wrench. The power drive of the lithium battery wrench enables mechanized operation, significantly improving efficiency.

[0032] For example, in the second embodiment of this utility model Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a rail chamfering device that can be installed quickly is provided, including a three-bladed chamfering cutter 1, a fixing cover 7, a clamp 5 and a base 3;

[0033] The base 3 is vertically and coaxially arranged from bottom to top with a base 31, a first male head 32, and a second male head 33. The gripper 5 is frustum-shaped and its bottom end is slidably connected to the top end of the first male head 32. A hollow fixing cover 7 is coaxially arranged above the base 31. The upper end of the fixing cover 7 is a frustum-shaped fastening head 71, and the lower end of the fixing cover 7 is a cylindrical first female head 72. The first female head 72 is connected to the first male head 32. The fastening head 71 is located outside the gripper 5 and is slidably connected to the gripper 5. A three-edged chamfering cutter 1 is coaxially arranged above the base 3. The bottom end of the three-edged chamfering cutter 1 passes through the fixing cover 7 and the gripper 5 in sequence and is detachably connected to the second male head 33. When the fixing cover 7 slides down, the fastening head 71 will push the gripper 5 horizontally toward the central axis, so that the gripper 5 fixes the three-edged chamfering cutter 1 in a vertical position.

[0034] Combination Figure 8 As shown, a support 4 is coaxially arranged above the second male head 33. The bottom end of the support 4 is provided with an inwardly recessed second female head 41. The size of the second female head 41 matches the size of the second male head 33. The second female head 41 and the second male head 33 are slidably connected. The top end of the support 4 is provided with a third male head 42. The bottom end of the three-bladed chamfering cutter 1 is provided with an inwardly recessed third female head 11. The size of the third male head 42 matches the size of the third female head 11. The third male head 42 and the third female head 11 are slidably connected.

[0035] The sliding connection between the third male head 42 and the third female head 11 allows the three-bladed chamfering cutter 1 to be coaxially connected with the support 4. The second female head 41 and the second male head 33 at the bottom of the support 4 are inserted and connected, so that the support 4 and the base 3 are coaxially fixedly connected, thereby keeping the three-bladed chamfering cutter 1 and the base 3 in a coaxial vertical position.

[0036] The outer wall of the second male head 33 is provided with a coaxial spring 6. One end of the spring 6 is fixed to the top of the first male head 32, and the other end of the spring 6 is fixed to the bottom of the support 4.

[0037] Spring 6 is located at the bottom of support 4. Spring 6 is used to relieve the impact of the three-bladed chamfering tool 1 on the base 3 when it is in operation.

[0038] The outer wall of the first male head 32 is provided with an external thread, and the inner wall of the first female head 72 is provided with an internal thread. The external thread and the internal thread are matched. The first male head 32 and the first female head 72 are threadedly connected. When the first female head 72 rotates through the thread, the jaw 5 rotates around the axis along with the fixing cover 7. When the first female head 72 moves downward through the thread, the jaw 5 is pushed towards the axis by the fastening head 71, so that the jaw 5 fixes the three-edged chamfering cutter 1.

[0039] Combination Figure 9 As shown, the inner wall of the fastening head 71 is provided with an inward dovetail groove 711. The dovetail groove 711 is located between the top and bottom ends of the fastening head 71. The number of dovetail grooves 711 is the same as the number of dovetail tenons 52. The size of the dovetail groove 711 matches the size of the dovetail tenon 52. The dovetail tenon 52 can slide on the dovetail groove 711. The fixing cover 7 is slidably connected to the clamp 5.

[0040] The sliding connection between the dovetail groove 711 and the dovetail tenon 52 allows the clamping jaws to rotate along with the fastening head 71 as it rotates around its own axis. When the fastening head 71 moves downward, the upper end of the frustum-shaped fastening head 71 will cause the upper end of the clamping jaws 5 to exert pressure on the axis of the clamping jaws 5, so as to keep the three-edged chamfering cutter 1 fixed.

[0041] In this embodiment, when in use, the third female head 11 at the bottom of the three-bladed chamfering cutter 1 is first inserted into the third male head 42 at the top of the support 4, so that the three-bladed chamfering cutter 1 is connected to the support 4 and the three-bladed chamfering cutter 1 is kept in a vertical position. Then, the fixing cover 7 is moved downward spirally, so that the fastening head 71 pushes the clamp 5 and keeps the three-bladed chamfering cutter 1 fixed.

[0042] The base 31 of this embodiment is then combined and fixed with the socket wrench head to achieve quick installation of this embodiment. The socket wrench head and the lithium battery wrench are quickly installed, and the power drive of the lithium battery wrench realizes mechanized operation, which significantly improves efficiency.

[0043] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of this utility model.
