Description

Technical Field

[0001] This utility model relates to the field of motor drilling technology, and in particular to a device for drilling holes in motor housings. Background Technology

[0002] Drilling is the process of making holes in solid materials with a drill bit. Aside from some of the hole making for various parts being done by machine tools such as lathes, boring machines, and milling machines, a large part of the hole making is done by fitters using drilling machines and drilling tools (drill bits, reamers, etc.). There are many kinds of existing drilling devices for machining motor housings. However, these devices often lack a secure grip on the motor housing during use, making the housing unstable and prone to damaging the drill bit or resulting in inaccurate drilling. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing drilling devices for motor housing processing, which are diverse and lack fixation for the motor housing during use, resulting in instability of the motor housing during drilling, which can easily lead to damage to the drill bit or insufficient drilling accuracy. This utility model provides a drilling device for motor housing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a drilling device for a motor housing, comprising a base, a punching assembly fixedly connected to the outer surface of the base, a fixing plate fixedly connected to the outer surface of the base, an air pump fixedly connected to the outer surface of the fixing plate, a telescopic rod fixedly connected to one end of the air pump, a clamping plate connected to the outer surface of the telescopic rod, a first fixing rod fixedly connected to the inner wall of the clamping plate, a rotating roller sleeved on the outer surface of the first fixing rod, a limiting rod fixedly connected to the outer surface of the base, and a motor housing sleeved on the outer surface of the limiting rod.

[0005] In a preferred embodiment, a connecting rod is fixedly connected to one end of the clamping plate, a buckle is sleeved on one end of the connecting rod, a torsion spring is sleeved on the outer surface of the connecting rod, a second fixing rod is fixedly connected to the outer surface of the buckle, a rotating rod is sleeved on the outer surface of the second fixing rod, and the rotating rod is rotatably connected to the second fixing rod.

[0006] In a preferred embodiment, one end of the connecting rod is rotatably connected to the inner wall of the buckle, one end of the torsion spring is fixedly connected to one side of the buckle, and the other end of the torsion spring is fixedly connected to one side of the clamping plate.

[0007] In a preferred embodiment, the outer surface of the first fixed rod is rotatably connected to the inner wall of the rotating roller.

[0008] In a preferred embodiment, the outer surface of the limiting rod is engaged with the inner wall of the motor housing.

[0009] In one preferred embodiment, a groove is provided at one end of the motor housing, and the outer surface of the groove is engaged with the outer surface of the buckle.

[0010] In a preferred embodiment, one side of the clamp is fixedly connected to one end of the telescopic rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention utilizes a punching assembly to punch holes in the motor housing. An air pump drives a telescopic rod, which in turn moves a clamping plate, initially fixing the motor housing, which is fitted onto a limiting rod. To pinpoint the punching location, the motor housing is rotated. A first fixing rod is rotatably connected to a rotating roller, which fits snugly against the motor housing, facilitating rotation and positioning. Once positioned, a torsion spring drives a buckle to rotate around the connecting rod, engaging with a groove on the outer surface of the motor housing for fixation. The air pump then drives the telescopic rod to move further, moving the clamping plate and ensuring a tight fit between the rotating roller and the motor housing, thus securing the motor housing and preventing rotation during punching.

[0019] 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.

[0020] Example 1

[0021] like Figures 1-3 As shown, this utility model provides a technical solution: a drilling device for a motor housing, including a base 1, a punching assembly 2 fixedly connected to the outer surface of the base 1, a fixing plate 3 fixedly connected to the outer surface of the base 1, an air pump 4 fixedly connected to the outer surface of the fixing plate 3, a telescopic rod 5 fixedly connected to one end of the air pump 4, a clamping plate 8 connected to the outer surface of the telescopic rod 5, a first fixing rod 10 fixedly connected to the inner wall of the clamping plate 8, a rotating roller 9 sleeved on the outer surface of the first fixing rod 10, the outer surface of the first fixing rod 10 rotatably connected to the inner wall of the rotating roller 9, a limiting rod 6 fixedly connected to the outer surface of the base 1, and a motor housing 7 sleeved on the outer surface of the limiting rod 6.

[0022] In this embodiment, the punching assembly 2 punches holes in the motor housing 7. The air pump 4 drives the telescopic rod 5 to move, and the movement of the telescopic rod 5 drives the clamping plate 8 to move, initially fixing the motor housing 7, which is sleeved on the limiting rod 6. When positioning the position where the punching is needed, the motor housing 7 needs to be rotated for positioning. The first fixing rod 10 is rotatably connected to the rotating roller 9, and the rotating roller 9 is in contact with the motor housing 7, making it convenient for the operator to rotate the motor housing 7 to achieve the purpose of positioning the motor housing 7. Then, the air pump 4 drives the telescopic rod 5 to continue moving, thereby driving the clamping plate 8 to move, so that the rotating roller 9 is tightly in contact with the motor housing 7, thereby fixing the motor housing 7 and ensuring that the motor housing 7 will not rotate during punching.

[0023] Example 2

[0024] like Figures 1-4 As shown, a connecting rod 13 is fixedly connected to one end of the clamping plate 8, and a buckle 11 is sleeved on one end of the connecting rod 13. A groove is opened at one end of the motor housing 7, and the outer surface of the groove is engaged with the outer surface of the buckle 11. A torsion spring 14 is sleeved on the outer surface of the connecting rod 13. A second fixing rod 15 is fixedly connected to the outer surface of the buckle 11. A rotating rod 12 is sleeved on the outer surface of the second fixing rod 15. The rotating rod 12 is rotatably connected to the second fixing rod 15. One end of the connecting rod 13 is rotatably connected to the inner wall of the buckle 11. One end of the torsion spring 14 is fixedly connected to one side of the buckle 11, and the other end of the torsion spring 14 is fixedly connected to one side of the clamping plate 8.

[0025] In this embodiment, after positioning, the torsion spring 14 drives the buckle 11 to rotate around the connecting rod 13, thereby engaging with the groove on the outer surface of the motor housing 7 to fix the motor housing 7. By setting the rotating rod 12 to be rotatably connected to the second fixing rod 15, it is easier for the staff to rotate the motor housing 7 more smoothly and to complete the positioning work of the motor housing 7.

[0026] Working principle:

[0027] like Figures 1-4 As shown, in this utility model, the worker first places the motor housing 7 onto the outer surface of the limiting rod 6, and then moves the telescopic rod 5 by the air pump 4. The movement of the telescopic rod 5 moves the clamping plate 8, initially fixing the motor housing 7 that is placed on the limiting rod 6. When positioning the position where the motor housing 7 needs to be punched, the motor housing 7 needs to be rotated for positioning. The first fixing rod 10 is rotatably connected to the rotating roller 9, and the rotating roller 9 is in contact with the motor housing 7, making it convenient for the worker to rotate the motor housing 7, thereby achieving the purpose of positioning the motor housing 7. After positioning, the torsion spring 14 drives the buckle 11. The rotating rod 13 rotates around the connecting rod 13, thereby engaging with the groove on the outer surface of the motor housing 7 to fix the motor housing 7. The rotating rod 12 is rotatably connected to the second fixing rod 15, making it easier for the operator to rotate the motor housing 7 and to complete the positioning work of the motor housing 7. Then, the air pump 4 drives the telescopic rod 5 to continue moving, thereby driving the clamping plate 8 to move, so that the rotating rod 9 fits tightly with the motor housing 7, thereby fixing the motor housing 7 and ensuring that the motor housing 7 will not rotate during punching. After the motor housing 7 is fixed, the punching assembly 2 is used to punch the motor housing 7.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
