Description

Technical Field

[0001] This utility model relates to the field of drilling positioning equipment, and in particular to a drilling positioning device for motor housing processing. Background Technology

[0002] In the field of motor manufacturing, drilling of motor housings is a critical process, and its accuracy directly affects the assembly and performance of the motor. Traditionally, motor housing drilling and positioning rely heavily on manual operation or simple fixtures. Manual positioning is inefficient; workers must rely on experience, visual inspection, or simple measuring tools to determine the drilling position, which easily leads to positioning errors, causing deviations in the drilling position, affecting the quality of the motor housing, increasing the defect rate, and raising production costs. Furthermore, manual operation requires repeating the positioning steps for each motor housing, making rapid clamping and positioning impossible, severely restricting production efficiency and making it difficult to meet the demands of large-scale production.

[0003] While common simple clamps can improve positioning efficiency to some extent, they lack versatility. Different sizes of motor housings require different clamps, and companies need to purchase a variety of clamps to meet production needs. This not only increases equipment procurement costs but also occupies a lot of storage space.

[0004] In addition, these types of fixtures usually lack effective adjustment devices. When faced with motor housings of different shapes and sizes, it is difficult to flexibly adjust the positioning method, resulting in inaccurate positioning and unstable clamping. During drilling, the motor housing is prone to displacement and vibration, which in turn affects the drilling accuracy and quality, and may even damage the drilling equipment and increase the equipment maintenance burden. Therefore, a drilling positioning device for motor housing processing is proposed to solve the above problems. Utility Model Content

[0007] As a further description of the above technical solution: the auxiliary component includes an auxiliary groove, and an auxiliary pointer is rotatably connected to the inner wall of the auxiliary groove.

[0008] As a further description of the above technical solution: an exhaust valve is provided on the right surface of the positioning clamp.

[0009] As a further description of the above technical solution: the output pipe of the air pump is connected to the outer wall of the positioning clamp.

[0010] As a further description of the above technical solution: the interior of the positioning clamp is configured as a hollow structure, and the top corner of the positioning clamp is configured as a rounded corner structure.

[0011] As a further description of the above technical solution: the bottom of the slider is slidably connected to the inner wall of the slide rail.

[0012] As a further description of the above technical solution: the positioning block is fixedly installed on the telescopic end of the electric telescopic pole.

[0023] 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.

[0024] Reference Figures 1-2 This utility model provides an embodiment of a motor housing machining drilling and positioning device, including a machining table 1. The machining table 1 serves as the basic support component of the entire motor housing machining drilling and positioning device, providing installation and fixing positions for other components such as the electric telescopic rod 2 and the scale strip 5, ensuring the stability of the entire device. Electric telescopic rods 2 are fixedly installed on both the left and right ends of the upper surface of the machining table 1. The electric telescopic rods 2 are mounted on the machining table 1, and their telescopic movement drives the positioning component 3 to move horizontally, allowing the positioning clamp 37 to be adjusted to a suitable length to adapt to the positioning requirements of motor housings of different lengths. A scale bar 5 is fixedly installed on the front end of the upper surface of the workbench 1. The scale bar 5 provides a position reference for the movement of the positioning component 3 in the left and right directions, which makes it convenient for the processing personnel to accurately adjust the position of the positioning component 3 according to the position of the motor housing. The telescopic end of the electric telescopic rod 2 is provided with a positioning component 3. The positioning component 3 is used to clamp the motor housing and includes components such as positioning block 31, slide rail 32, electric push rod 33, slider 34, lifting rod 35, air pump 36, positioning clamp 37, air bag 38 and exhaust valve 39. The components work together to achieve accurate positioning of the motor housing. An auxiliary component 4 is provided on the front surface of the positioning component 3.

[0025] Reference Figures 2-4The positioning component 3 includes a positioning block 31, which is fixedly installed on the telescopic end of the electric telescopic rod 2. The positioning block 31 serves as the main load-bearing structure of the positioning component 3, providing a mounting base for components such as the slide rail 32 and the electric push rod 33, enabling the positioning component 3 to form a complete structural system. A slide rail 32 is provided on the upper surface of the positioning block 31, providing a sliding track for the slider 34, allowing the slider 34 to slide left and right on the positioning block 31, thereby driving the positioning clamp 37 to move left and right to adapt to the shape characteristics of different motor housings. Electric push rods 33 are fixedly installed at both the front and rear ends of the upper surface of the positioning block 31. The electric push rods 33 drive the slider 34 to move along the slide rail 32 through telescopic movements, realizing the position adjustment of the positioning clamp 37 in the front-rear direction. A slider 34 is fixedly installed at the output end of the electric push rod 33, and the bottom of the slider 34 is slidably connected to the inner wall of the slide rail 32. A lifting rod 35 is fixedly installed on the upper surface of the slider 34. The lifting rod 35 adjusts the height of the positioning clamp 37 through lifting movements, adapting it to the positioning requirements of different height directions of the motor housing. An air pump 36 is installed at the top of the lifting rod 35. The air pump 36 provides air pressure to the airbag 38 inside the positioning clamp 37, causing the airbag 38 to inflate and clamp the motor housing. The positioning clamp 37 is fixedly connected to the right side of the lifting end of the lifting rod 35. The positioning clamp 37 has a hollow internal structure and rounded corners. The output pipe of the air pump 36 is connected to the outer wall of the positioning clamp 37. The positioning clamp 37 is used to directly clamp the motor housing, and the inflation of the airbag 38 achieves clamping of the motor housing. The positioning clamp 37 has multiple air bladders 38 detachably connected to its inner arc surface. These air bladders expand under the action of the air pump 36, tightly fitting the outer surface of the motor housing during expansion and generating clamping force. This allows the positioning clamp 37 to adapt to various motor housings with irregular outer walls, improving its adaptability to motor housings and enhancing the positioning effect of the equipment. An exhaust valve 39 is provided on the right surface of the positioning clamp 37 to discharge the gas inside the positioning clamp 37. When the motor housing needs to be removed after processing, the exhaust valve 39 is opened to cause the air bladders 38 to contract.

[0026] Reference Figures 2-4 The auxiliary component 4 includes an auxiliary groove 41, which is formed on the front surface of the positioning block 31. The auxiliary groove 41 provides space for the installation and rotation of the auxiliary pointer 42, allowing the auxiliary pointer 42 to rotate flexibly. The auxiliary pointer 42 is rotatably connected to the inner wall of the auxiliary groove 41. The auxiliary pointer 42 works in conjunction with the scale bar 5. When the positioning component 3 moves, the auxiliary pointer 42 indicates the specific position of the positioning component 3 in the left and right directions, helping the processing personnel to accurately control the position of the positioning component 3.

[0027] Working principle:

[0028] Place the motor housing on the processing table 1. Adjust the extension length of the electric telescopic rod 2 according to the size and shape of the motor housing, so that the positioning component 3 is roughly moved to the vicinity of the motor housing. Using the scale bar 5 on the processing table 1 as a reference and the position indicated by the auxiliary pointer 42 in the auxiliary component 4, use the extension and retraction of the electric telescopic rod 2 to precisely adjust the position of the positioning component 3 in the left and right directions, so that the positioning clamp 37 is aligned with the position to be processed on the motor housing. Activate the electric push rod 33 in the positioning component 3 to drive the slider 34 to move along the slide rail 32, thereby adjusting the position of the positioning clamp 37 in the front and back directions to further adapt to the shape characteristics of the motor housing and ensure that the positioning clamp 37 can accurately clamp the motor housing. Control the lifting action of the lifting rod 35 to adjust the height of the positioning clamp 37 to match the height of the motor housing, ensuring that the positioning clamp 37 can closely contact the outer surface of the motor housing.

[0029] The air pump 36 is activated, and gas is injected into the air bladder 38 inside the positioning clamp 37 through the pipeline, causing the air bladder 38 to inflate and thus firmly clamp the motor housing within the positioning clamp 37. The expansion of the air bladder 38 can adapt to the irregular shape of the outer wall of the motor housing, improving the accuracy and stability of positioning. After the motor housing is accurately positioned and clamped, drilling equipment is used for drilling operations. Because the motor housing is firmly clamped, vibration and displacement during the drilling process are effectively controlled, ensuring the accuracy and quality of drilling.

[0030] After drilling is completed, open the exhaust valve 39 on the positioning clamp 37 to release the gas inside the air bladder 38, causing the air bladder 38 to contract and thus loosening the motor housing. At this point, the machined motor housing can be removed from the positioning clamp 37.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
