[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0036] Example 1:

[0037] like Figure 1 As shown, embodiment 1 of the present invention provides a tool for processing a buzzer shell, comprising a base body 1 and a fixing assembly 2; the base body 1 is provided with a through opening 11 from top to bottom; a space for placing the buzzer shell is provided in the through opening 11; the fixing assembly 2 is arranged on the base body 1; when the buzzer shell is placed in the through opening 11, the fixing assembly 2 can clamp the buzzer shell in the left and right directions, and the fixing assembly 2 limits the buzzer shell in the vertical and horizontal directions.

[0039] The tooling for processing a buzzer housing provided in Example 1 of the present invention comprises a base body 1 and a fixing assembly 2; the base body 1 is provided with a through-hole 11 from top to bottom, through which the buzzer housing can be placed in the base body 1, or through which the third opening 07 on the buzzer housing can be processed, and a boring tool is inserted from the through-hole 11 to grind the third opening 07 and further enlarge the third opening 07; further, the fixing assembly 2 is provided on the base body 1, and the fixing assembly 2 is fixed to the base body 1. When the buzzer shell is arranged in the through-opening 11, the fixing component 2 clamps the buzzer shell in the left and right directions, and the fixing component 2 limits the buzzer shell in the vertical and horizontal directions, so that the buzzer shell is subjected to extrusion force in the left and right directions. At the same time, the buzzer shell cannot be displaced in the vertical and horizontal directions, so that when the boring tool further processes the third opening 07 on the buzzer shell, the buzzer shell can be prevented from tilting or shaking, thereby avoiding damage to the buzzer shell when the boring tool rotates.

[0040] like Figure 2 As shown, the tooling for processing the buzzer shell provided by Example 1 of the present invention, preferably, in order to realize clamping the buzzer shell by the fixing component 2, the fixing component 2 includes a first limiting component 21 and a second limiting component 22, the first limiting component 21 and the second limiting component 22 are both arranged on the inner side of the base body 1, the first limiting component 21 is arranged on the left side of the base body 1, and the second limiting component 22 is arranged on the right side of the base body 1, when the buzzer shell is placed in the through-opening 11, the buzzer shell is located between the first limiting component 21 and the second limiting component 22; further, the first limiting component 21 can be moved toward the second limiting component 22, when the buzzer shell needs to be clamped, the first limiting component 21 is moved toward the second limiting component 22, at this time, the first limiting component 21 is against the bottom of the second extension part 06 in the buzzer shell, and the second limiting component 22 is against the top of the connecting member 04 in the buzzer shell, thereby realizing the clamping effect of the fixing component 2 on the buzzer shell.

[0041] like Figures 2-4 As shown, the tooling for processing the buzzer housing provided by Example 1 of the present utility model, preferably, in order to realize the function that the first limiting component 21 can move toward the second limiting component 22, the first limiting component 21 includes a first limiting component 211 and a first bolt 212, a first screw hole 12 is opened on the left side of the base body 1, and the first bolt 212 is rotatably disposed in the first screw hole 12, and the length of the first bolt 212 extending into the inner side of the base body 1 is controlled by screwing the first bolt 212, thereby controlling the movement of the first limiting component 211;

[0042] Furthermore, in order to limit the buzzer housing in the horizontal and vertical directions, the first limiting member 21 includes a first circular plate 2111 and a second circular plate 2112. The first circular plate 2111 and the second circular plate 2112 are vertically arranged. The first circular plate 2111 is located on the left side of the second circular plate 2112. The first circular plate 2111 is fixed to the left side of the second circular plate 2112, and the diameter of the first circular plate 2111 is larger than that of the second circular plate 2112, thereby forming a stacked structure, so that the second circular plate 2111 is sleeved in the second extension portion 06. , the arc side wall of the second circular plate 2111 is tightly fitted with the inner circular side wall of the second extension portion 06, and at this time, the bottom of the second extension portion 06 is in contact with the right side of the first circular plate 2111; further, the axis of the first circular plate 2111 and the axis of the second circular plate 2112 coincide with each other, so that the bottom of the second extension portion 06 can fully contact the right side of the first circular plate 2111, thereby increasing the friction between the second extension portion 06 and the first circular plate 2111, preventing the buzzer housing from rotating under force when being pressed, thereby preventing the boring tool from deviating from the processing position;

[0043] The second limiting assembly 22 includes a second limiting member 221 and a second bolt 222. A second screw hole 13 is provided on the right side of the base body 1. The second bolt 222 is rotatably disposed in the second screw hole 13. By tightening the second bolt 222, the second limiting assembly 22 can be fixed to the right end of the base body 1.

[0044] Furthermore, in order to realize the limiting function of the second limiting member 221, similar to the first limiting member 21, the second limiting member 221 includes a third circular plate 2211 and a fourth circular plate 2212, the third circular plate 2211 and the fourth circular plate 2212 are vertically arranged, the third circular plate 2211 is located on the right side of the fourth circular plate 2212, the third circular plate 2211 is fixed to the right side of the fourth circular plate 2212, and the diameter of the third circular plate 2211 is larger than that of the fourth circular plate 2212, forming a stacked structure, so that the fourth circular plate 2212 is sleeved in the connecting member 04, and the arc side wall of the fourth circular plate 2212 is aligned with the connecting member 04. The inner circular side wall of the connecting member 04 is tightly fitted. At this time, the top of the connecting member 04 is in contact with the left side of the third circular plate 2211. At this time, the two ends of the buzzer housing are clamped by the first circular plate 2111 and the third circular plate 2211. Since the second circular plate 2112 is sleeved in the second extension portion 06 and the fourth circular plate 2212 is sleeved in the connecting member 04, the buzzer housing is blocked by the second circular plate 2112 and the fourth circular plate 2212. It cannot move in the vertical direction and the horizontal direction, thereby preventing the buzzer housing from tilting or shaking, and further preventing the buzzer housing from being damaged when the boring tool rotates;

[0045] Furthermore, the axis of the third circular plate 2211 coincides with the axis of the fourth circular plate 2212, so that the top of the connector 04 can fully contact the left side of the third circular plate 2211, thereby increasing the friction between the connector 04 and the third circular plate 2211, thereby preventing the buzzer housing from rotating under force when being pressed, thereby preventing the boring cutter from deviating from the processing position;

[0046] Furthermore, since the axes of the two end surfaces of the buzzer housing coincide with each other, the axis of the second circular plate 2112 is made to coincide with the axis of the fourth circular plate 2212, so that the second circular plate 2112 and the fourth circular plate 2212 can be simultaneously sleeved inside the two ends of the buzzer housing, so that the arc side wall of the second circular plate 2112 is tightly fitted with the inner circular side wall of the second extension portion 06, and the arc side wall of the fourth circular plate 2212 is tightly fitted with the inner circular side wall of the connecting member 04, thereby playing a good limiting role.

[0047] A third screw hole 22111 is provided on the right side of the third circular plate 2211 for fixing. The second bolt 222 is screwed into the third screw hole 13. The second bolt 222 passes through both the second screw hole 13 and the third screw hole 22111 to fix the second limiting member 221 to the base 1.

[0048] When the buzzer housing is between the first circular plate 2111 and the third circular plate 2211, and the first limiting member 211 and the second limiting member 221 clamp the buzzer housing, in order to enable the first circular plate 2111 to press the bottom of the second extension portion 06, it is necessary to make the first bolt 212 press against the left side of the first circular plate 2111. Since the end of the bolt screw is smooth, it is easy to slide when it contacts the left side of the first circular plate 2111, so that the first bolt 212 cannot press against the first circular plate 2111. For this reason, a concave hole 21111 for limiting is opened on the left side of the first circular plate 2111. The axis of the concave hole 21111 coincides with the axis of the first circular plate 2111. The end of the screw rod of the first bolt 212 is in the concave hole 21111. 1111, so that when the screw rod of the first bolt 212 presses against the first circular plate 2111, the pressure brought by the first bolt 212 can be evenly distributed to the contact surface between the first circular plate 2111 and the second extension portion 06, thereby avoiding tilting due to uneven force on the buzzer shell, and the concave hole 21111 can prevent the screw rod end of the first bolt 212 from sliding, so that the first bolt 212 can stably press against the first circular plate 2111; further, the end of the screw rod of the first bolt 212 is conical, and the conical end can better extend into the concave hole 21111, and has a smaller contact area with the edge of the concave hole 21111, which can increase the pressure between the first bolt 212 and the concave hole 21111, and prevent the first circular plate 2111 from falling off.

[0049] like Figures 1-4As shown, the tooling for processing the buzzer housing provided by Example 1 of the present invention preferably further includes a guide assembly 3 for guiding the boring tool into the inner side of the base body 1 in order to make it easier for the boring tool to be positioned at the third opening 07 and improve the boring accuracy of the boring tool.

The top surface of the first fixing member 321 is flush with the top surface of the second fixing member 322, so that the bottom of the second fixing member 322 protrudes compared to the bottom of the first fixing member 321. The inner circular sidewall of the second fixing member 322 is used to guide the boring tool to enter, limiting the size of the boring tool boring the third opening 07 and the processing position of the third opening 07 on the buzzer housing.

The bottom surface of the first fixing member 321 is in close contact with the side wall of the base 1. When installing the guide member 32, the bottom end of the second fixing member 322 is directed toward the opening 14, and the guide member 32 is inserted into the opening 14 from the outside of the base 1. At this time, the first fixing member 321 can be stuck on the outer surface of the base 1, making it easier to install and position.
