Description

Technical Field

[0001] This utility model relates to the technical field of motor inner housing processing equipment, specifically a motor inner housing drilling fixture. Background Technology

[0002] During the drilling process of the motor inner housing, the positioning accuracy of the drilling fixture directly affects the drilling quality and efficiency. The traditional positioning method is to set a ring on the base and place the motor inner housing directly on the ring for positioning. Although this positioning method is simple and easy to implement, it has significant limitations in practical applications.

[0003] Temperature changes during processing cause thermal expansion and contraction of the motor's inner housing, leading to variations in the clearance between the inner housing and the ring, which in turn affects positioning accuracy. This inaccurate positioning not only causes drilling position deviations but may also trigger quality issues in subsequent processing. Therefore, it is necessary to design a drilling fixture that can overcome the effects of thermal expansion and contraction and improve positioning accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drilling fixture for the inner casing of a motor, which solves the problem of positioning deviations that easily occur in current drilling fixtures for the inner casing of motors.

[0005] This utility model discloses a drilling fixture for an inner casing of a motor, comprising a base plate, a positioning ring, a support assembly, a limiting assembly, an anti-deviation mechanism, and a second clamping structure. Three support seats arranged in an equilateral triangle are fixedly connected to the top of the base plate. A first clamping structure is provided on the upper surface of each support seat. The positioning ring is fixedly connected to the upper surface between the three support seats. A first boss and a second boss are integrally formed on the side of the positioning ring. The support assembly is fixedly connected to the upper surface of the positioning ring and corresponds to the position of the first clamping structure. The limiting assembly is fixedly connected to the upper surface of the positioning ring. The anti-deviation mechanism is fixedly connected to the upper surface of the first boss. The second clamping structure is fixedly connected to the upper surface of the second boss.

[0006] As a further improvement of this utility model, the first clamping structure includes a first screw, a second screw, and a clamping plate. The first screw and the second screw are fixedly connected side by side to the upper surface of the support base, and the clamping plate is slidably connected between the first screw and the second screw in the vertical direction.

[0007] As a further improvement of this utility model, the first clamping structure further includes a support nut and a clamping nut. The support nut is threadedly connected to the surface of the clamping plate and located below the clamping plate, while the clamping nut is threadedly connected to the surface of the second screw and located above the clamping plate.

[0008] As a further improvement of this utility model, the support component includes three support blocks, which are fixedly connected to the upper surface of the positioning ring in the form of an equilateral triangle, and the positions of the three support blocks correspond one-to-one with the positions of the three first pressing structures.

[0009] As a further improvement of this utility model, the limiting component includes two limiting blocks, and the two limiting blocks and the anti-deviation mechanism are arranged in a triangle above the positioning ring.

[0010] As a further improvement of this utility model, the anti-deviation mechanism includes a first cylinder, and a first push block is fixedly connected to the output end of the first cylinder.

[0011] As a further improvement of this utility model, the second pressing structure includes a second cylinder, and a second push block is fixedly connected to the output end of the second cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a support block to support the lower surface of the flange end of the motor inner housing. With the help of the first screw, second screw, pressure plate, support nut and pressure nut, the upper surface of the flange end of the motor inner housing can be pressed and fixed. With the help of the limit block, first cylinder and first push block, the surface of the motor inner housing can be clamped and positioned. With the help of the second push block on the second cylinder, the outer side of the flange end of the motor inner housing can be clamped and positioned to prevent rotation during processing.

[0013] 2. This utility model effectively solves the problem of inaccurate positioning of the motor inner housing due to thermal expansion and contraction in the prior art by positioning the motor inner housing from the outside. It achieves all-round fixation through bidirectional clamping, further eliminating positioning errors. This design significantly improves drilling accuracy, avoids processing defects caused by inaccurate positioning, simplifies the operation process, and improves production efficiency.

[0016] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0017] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0019] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] Please see Figure 1-7This utility model discloses a drilling fixture for an inner casing of a motor, comprising a base plate 1, a positioning ring 8, a support assembly, a limiting assembly, an anti-offset mechanism, and a second clamping structure. Three support seats 2 arranged in an equilateral triangle are fixedly connected to the top of the base plate 1. The upper surface of each support seat 2 is provided with a first clamping structure. The positioning ring 8 is fixedly connected to the upper surface between the three support seats 2. The sides of the positioning ring 8 are integrally formed with a first boss 11 and a second boss 14. The support assembly is fixedly connected to the upper surface of the positioning ring 8 and corresponds to the position of the first clamping structure. The limiting assembly is fixedly connected to the upper surface of the positioning ring 8. The anti-offset mechanism is fixedly connected to the upper surface of the first boss 11. The second clamping structure is fixedly connected to the upper surface of the second boss 14.

[0021] like Figure 2 and Figure 5 As shown, in this embodiment, the first clamping structure includes a first screw 3, a second screw 4, and a clamping plate 5. The first screw 3 and the second screw 4 are fixedly connected side by side to the upper surface of the support base 2, and the clamping plate 5 is slidably connected between the first screw 3 and the second screw 4 in the vertical direction. The first clamping structure also includes a support nut 6 and a clamping nut 7. The support nut 6 is threaded to the surface of the clamping plate 5 and is located below the clamping plate 5. The clamping nut 7 is threaded to the surface of the second screw 4 and is located above the clamping plate 5.

[0022] Through the above technical solution, the position of the clamping plate 5 can be adjusted by adjusting the position of the support nut 6 and the clamping nut 7. The support nut 6 is located below the clamping plate 5 to support the height, and the clamping nut 7 is located above to press down and fix it, so that the clamping plate 5 can be stably attached to the upper surface of the flange end of the motor inner housing.

[0023] like Figure 3 and Figure 5 As shown, in this embodiment, the support component includes three support blocks 9, which are fixedly connected to the upper surface of the positioning ring 8 in the form of an equilateral triangle. The positions of the three support blocks 9 correspond one-to-one with the positions of the three first pressing structures.

[0024] Specifically, the three support blocks 9 are located directly below the ends of the three clamping plates 5, and together with the clamping plates 5, they form a clamping structure that can effectively clamp and fix the flange end of the motor inner housing.

[0025] Please see Figure 3 and Figure 5 In this embodiment, the limiting component includes two limiting blocks 10. The two limiting blocks 10 and the anti-deviation mechanism are arranged in a triangle above the positioning ring 8. The anti-deviation mechanism includes a first cylinder 12, and the output end of the first cylinder 12 is fixedly connected to a first push block 13.

[0026] The "triangular distribution" of the limiting components and the anti-deviation mechanism is achieved by arranging the two limiting blocks 10 and the first push block 13 in the anti-deviation mechanism into a triangular array on the positioning ring 8 to achieve multi-directional positioning. The two limiting blocks 10 and the first push block 13 are in contact with the outer surface of the motor inner housing, and the adjustable first push block 13 presses the motor inner housing laterally.

[0027] Please see Figure 3 and Figure 5 In this embodiment, the second pressing structure includes a second cylinder 15, and a second push block 16 is fixedly connected to the output end of the second cylinder 15. The end of the second push block 16 is a "V" shaped structure, which fits the arc edge of the flange end of the motor inner housing, so that the flange end of the motor inner housing can be inserted into the interior of the second push block 16 to prevent rotation during processing.

[0028] In summary, this utility model provides a high-efficiency and stable drilling fixture for the inner casing of a motor. The lower surface of the flange end of the inner casing of the motor is supported by the support block 9. In conjunction with the first screw 3, the second screw 4, the clamping plate 5, the support nut 6, and the clamping nut 7 of the first clamping structure, adjustable clamping is achieved on the upper surface of the flange end of the inner casing of the motor, ensuring that the workpiece is fixed in the vertical direction. At the same time, the limiting components and the anti-deviation mechanism are arranged in a triangle to clamp the casing from the side and prevent radial deviation. The second push block 16 in the second clamping structure clamps the flange end of the inner casing of the motor from the outside to prevent rotation during processing.

[0029] This design solves the problem of inaccurate positioning caused by thermal expansion and contraction in the prior art. By using multi-directional clamping and positioning, it eliminates errors, improves drilling accuracy and processing consistency, simplifies the operation process, and enhances production efficiency.

[0030] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
