Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a center positioning fixture for machining cylindrical machine housings. Background Technology

[0002] A cylindrical housing is a mechanical shell or structural component with a cylindrical shape. It is usually used as an external protection, support, or mounting carrier for equipment or parts. When existing spraying equipment sprays cylindrical housings, it is easy to cause problems such as inconsistent spraying distances because it uses some simple fixing fixtures to fix the cylindrical housing without positioning the center of the cylindrical housing. Furthermore, when the cylindrical housing is subjected to external forces, it will cause the cylindrical housing to shift during subsequent processing, resulting in fluctuations in the spraying process and causing uneven spraying, which affects the final spraying effect and product quality. Utility Model Content

[0003] In order to overcome the technical problems existing in the prior art, the present invention provides a center positioning tooling for machining cylindrical machine housings with center positioning function.

[0004] The technical implementation scheme of this utility model is as follows: A center positioning fixture for machining cylindrical machine housing includes a spraying device, a support block, a first motor, a gear, a gear ring, a placement ring, a second motor, a bidirectional lead screw, and a positioning post. The support block is fixedly connected to the top front side of the spraying device, and the first motor is fixedly connected to the bottom front side of the support block. The output shaft of the first motor is fixedly connected to a gear, which is located at the top front side of the support block. The top of the support block is rotatably connected to a placement ring, and a gear ring is fixedly connected to the placement ring. The gear and the gear ring mesh with each other. The placement ring is used to place the cylindrical machine housing. The second motor is fixedly connected to the middle right side of the support block, and the output shaft of the second motor is fixedly connected to a bidirectional lead screw. The bidirectional lead screw is rotatably connected to the support block. The positioning post is symmetrically slidably connected to the middle left and right sides of the support block, and the lower part of the positioning post is threadedly connected to the bidirectional lead screw.

[0005] In a preferred embodiment of this utility model, it further includes an adjusting screw, a connecting rod, and a ball bearing. The upper part of each positioning column is threaded with an adjusting screw, and a connecting rod is slidably connected between two adjusting screws. The ends of the adjusting screws are rotatably connected with ball bearings. The adjusting screws can be adjusted according to different dimensions of the cylindrical housing.

[0006] In a preferred embodiment of the present invention, an auxiliary block is also included, and the auxiliary block is fixedly connected to the middle part of the connecting rod.

[0007] In a preferred embodiment of the present invention, a protective cover is also included, with the top of the support block fixedly connected to the protective cover, and the gear located inside the protective cover.

[0008] In a preferred embodiment of the present invention, a telescopic pad is also included, and the telescopic pad is slidably connected to the middle of the support block, with the telescopic pad located above the bidirectional lead screw.

[0009] In a preferred embodiment of the present invention, an anti-slip pad is also included, and the top of the placement ring is fixedly connected to the anti-slip pad.

[0010] Compared with the prior art, the present invention has the following advantages: 1. By driving the bidirectional lead screw to rotate through the second motor, the positioning column is driven to position the inner wall of the cylindrical machine housing, thereby achieving precise positioning of the cylindrical machine housing in the horizontal direction, reducing the processing error that may be caused by the unstable position of the cylindrical machine housing, and improving the overall processing accuracy.

[0011] 2. By rotating the connecting rod, the adjusting screw is driven to rotate, causing the adjusting screw to extend outward along the thread direction of the positioning pin. This causes the ball bearings to fit tightly against the inner wall of the cylindrical housing, achieving precise adaptation to cylindrical housings of different specifications. This further stabilizes the position of the cylindrical housing and ensures that it will not shift during subsequent processing. Attached Figure Description

Detailed Implementation

[0017] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0018] Example: A center positioning fixture for machining cylindrical machine housings, such as... Figure 1-2 As shown, the device includes a spraying device 1, a support block 2, a first motor 3, a gear 4, a gear ring 5, a placement ring 6, a second motor 7, a bidirectional lead screw 8, and a positioning post 9. The support block 2 is fixedly connected to the top front side of the spraying device 1. The first motor 3 is fixedly connected to the bottom front side of the support block 2. The gear 4 is fixedly connected to the output shaft of the first motor 3. The gear 4 is located at the top front side of the support block 2. The placement ring 6 is rotatably connected to the top of the support block 2. The gear ring 5 is fixedly connected to the placement ring 6. The gear 4 and the gear ring 5 mesh with each other. The placement ring 6 is used to place a cylindrical housing. The second motor 7 is fixedly connected to the middle right side of the support block 2. The bidirectional lead screw 8 is fixedly connected to the output shaft of the second motor 7. The bidirectional lead screw 8 is rotatably connected to the support block 2. The positioning post 9 is symmetrically slidably connected to the middle left and right sides of the support block 2. The lower part of the positioning post 9 is threadedly connected to the bidirectional lead screw 8.

[0019] like Figure 1-4 As shown, it also includes an adjusting screw 10, a connecting rod 11, and a ball bearing 12. The adjusting screw 10 is threadedly connected to the top of each positioning post 9. The connecting rod 11 is slidably connected between the two adjusting screws 10. The ball bearing 12 is rotatably connected to the end of each adjusting screw 10. The adjusting screw 10 can be adjusted according to different dimensions of the cylindrical housing.

[0020] like Figure 1 As shown, it also includes an auxiliary block 13, which is fixedly connected to the middle part of the connecting rod 11.

[0021] like Figure 1 As shown, it also includes a protective cover 14. The top of the support block 2 is fixedly connected to the protective cover 14. The gear 4 is located inside the protective cover 14. The protective cover 14 can prevent external debris from entering the interior and affecting the normal operation of each component, thereby ensuring the stability of the cylindrical housing positioning.

[0022] like Figure 1 As shown, it also includes a telescopic pad 15, which is slidably connected to the middle of the support block 2. The telescopic pad 15 is located above the bidirectional lead screw 8. The telescopic pad 15 can prevent the spray liquid from entering the middle of the support block 2, thereby ensuring the normal operation of the internal components such as the bidirectional lead screw 8 and avoiding the normal use and service life of the tooling due to the intrusion of the spray liquid.

[0023] like Figure 1-2 As shown, it also includes an anti-slip pad 16, which is fixedly connected to the top of the placement ring 6.

[0024] When using this device, the cylindrical housing is placed on the placement ring 6. The anti-slip pad 16 increases the friction between the cylindrical housing and the placement ring 6, increasing stability. At this time, the cylindrical housing is not yet precisely positioned. Subsequently, the second motor 7 is started, driving the bidirectional lead screw 8 to rotate. As the bidirectional lead screw 8 rotates, the two positioning pins 9 move back-to-back along the support block 2 until the ball bearing 12 contacts the inner wall of the cylindrical housing, thus positioning the cylindrical housing and ensuring that the cylindrical housing is centered on the placement ring 6. When the size of the cylindrical housing is large, the operator rotates the auxiliary block 13 clockwise, driving the connecting rod 11 and the adjusting screw 1... The adjusting screw 10 extends outward along the thread direction of the positioning pin 9 by a certain length. During the extension process, the ball bearing 12 at the end of the adjusting screw 10 gradually and tightly fits the inner wall of the cylindrical housing, which reduces friction and adapts to different diameters, realizing rapid positioning of cylindrical housings of different specifications. After positioning is completed, the first motor 3 is started to operate. The first motor 3 drives the gear 4 to rotate. The gear ring 5 will rotate synchronously with the rotation of the gear 4. The cylindrical housing will rotate at a uniform speed with the rotation of the placement ring 6 and the gear ring 5. Subsequently, the spraying device 1 sprays the surface of the housing evenly in all directions to avoid uneven spraying, missed spraying, etc., and finally completes the high-quality spraying process of the cylindrical housing.

[0025] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
