Description

Technical Field

[0001] This utility model belongs to the technical field of tooling for balance block production, specifically relating to a tooling for balance block production. Background Technology

[0002] Rotor balance weights are components used to improve the dynamic balance of rotors. During the production of balance weights, strict quality control is required. The shape, size, and thickness of the balance weights are important aspects of quality control. Therefore, it is necessary to inspect the shape, size, and thickness of the balance weights to control product quality.

[0003] Utility model patent CN212620427U discloses a motor rotor balance block inspection fixture, including a go gauge plate and a no-go gauge plate. The go gauge plate has several go gauge slots that allow balance blocks of different specifications to pass through precisely. The go gauge plate also has several through holes. The upper surface of the no-go gauge plate has several no-go gauge slots that prevent balance blocks of different specifications from being inserted precisely. The upper surface of the no-go gauge plate has several guide posts. When the go gauge plate is stacked on the surface of the no-go gauge plate, the guide posts can pass through the through holes in the go gauge plate. This utility model provides a motor rotor balance block inspection fixture, which can quickly and accurately inspect whether the shape and dimensions of a balance block are up to standard.

[0004] The above-mentioned technology requires two steps to inspect the shape, size and holes on the balance block. During the inspection, the balance block is placed in the gauge groove, and after the inspection is completed, the balance block is difficult to remove, resulting in low inspection efficiency.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a tooling for the production of balance blocks.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figure 1 As shown, a tooling for producing balance blocks according to one embodiment of this utility model includes a go gauge plate 1 and a no-go gauge plate 2. The go gauge plate 1 has two go gauge grooves 101 of different sizes on one end face. One groove allows a first balance block 7 conforming to the standard to pass through, and the other allows a second balance block 8 conforming to the standard to pass through. The go gauge plate 1 can filter out balance blocks whose shape and size are larger than the standard size. The no-go gauge plate 2 has two no-go gauge grooves 201 of different sizes on one end face. One groove prevents the first balance block 7 conforming to the standard from passing through, and the other groove prevents the second balance block 8 conforming to the standard from passing through. The no-go gauge plate 2 can filter out balance blocks whose shape and size are smaller than the standard size. The go gauge plate 1 and the no-go gauge plate 2 are matched together to detect balance blocks whose shape and size meet the standard.

[0034] like Figure 6 As shown, the go gauge plate 1 and the no-go gauge plate 2 are fixedly connected together by bolts. Multiple first bolts 205 are fixedly connected to one end face of the no-go gauge plate 2. Multiple fixing holes 102 matching the first bolts 205 are opened on one end face of the go gauge plate 1. The first bolts 205 pass through the fixing holes 102 and are threaded to the nuts 206, thereby fixing the go gauge plate 1 to the no-go gauge plate 2. The screening of balance blocks with standard shape and size can be completed in one operation.

[0035] like Figure 5 and Figure 7 As shown, a plurality of first sliding holes 202 are provided on one side end face of the stop gauge plate 2. A hole inspection assembly 3 is slidably connected inside the side wall of the first sliding hole 202. The hole inspection assembly 3 includes a pair of stop gauge parts 302. The stop gauge parts 302 are slidably connected inside the side wall of the first sliding hole 202. A go gauge part 301 is integrally formed on one side end face of the stop gauge part 302. The go gauge part 301 can pass through the round hole of the standard balance block, while the stop gauge part 302 can just prevent the round hole of the standard balance block from passing through, thereby screening out the balance blocks that meet the standard for the round hole.

[0036] like Figure 2 As shown, the bottom end faces of a pair of stop gauge parts 302 are simultaneously welded to the same connecting part 303. A spring 210 is welded to the top end face of the connecting part 303. The other end of the spring 210 is welded to the ground of the stop gauge plate 2. The spring 210 pulls the connecting part 303 closer to the stop gauge plate 2, causing the top end faces of the go gauge part 301 and the stop gauge part 302 to protrude from the top end face of the go gauge plate 1. Thus, when inspecting the round hole of the balance block, it is not necessary to remove the hole inspection assembly 3. The balance block can be directly placed on the go gauge part 301 for inspection. After inspecting the round hole of the balance block, the balance block is pressed down into the go gauge groove 101 for shape and size inspection. Because the spring 210 is stretchable, when the round hole of the balance block is qualified, the balance block moves downward against the top end face of the stop gauge part 302. When the size of the round hole of the balance block is smaller than the standard, the balance block moves downward against the end face of the go gauge part 301. When the size of the balance block is larger than the standard value, the balance block can slide down along the side wall of the stop gauge part 302. Therefore, the go gauge part 301 and the stop gauge part 302 will not prevent the balance block from moving downward. The hole inspection assembly 3 does not need to be removed, and two inspections are not required. The balance block's round hole and shape dimensions can be checked simultaneously in one step.

[0037] A pair of third sliding holes 304 are provided on the connecting part 303. Multiple first fixing posts 207 that match the third sliding holes 304 are welded to one end face of the stop gauge plate 2. When the inspection assembly 3 slides up and down, the third sliding holes 304 are fitted on the side wall of the first fixing posts 207. The first fixing posts 207 can keep the inspection assembly 3 from shifting when sliding.

[0038] A second limiting block 208 is welded to one end face of the first fixing post 207. The bottom diameter of the second limiting block 208 is larger than the bottom diameter of the first fixing post 207. A second limiting groove 305 matching the second limiting block 208 is opened on one end face of the connecting part 303. The second limiting block 208 is engaged in the side wall of the second limiting groove 305. The second limiting block 208 can restrict the downward displacement of the inspection component 3, so that the inspection component 3 will not slip off the first fixing post 207, and the connection between the inspection component 3 and the stop plate 2 is more stable.

[0039] The opposite end face of the stop gauge plate 2 is integrally formed with a first handle 209, and the opposite end face of the connecting part 303 is integrally formed with a pair of second handles 306 that match the first handle 209. With the first handle 209 and the second handle 306 working together, when the inspection hole assembly 3 is stuck by the side wall of the first sliding hole 202, the inspection hole assembly 3 can be manually moved upward. At the same time, after the inspection is completed, the balance block can also be pushed out from the go gauge groove 101 by the stop gauge part 302.

[0040] In the slotted area of ​​the go gauge groove 101 on the stop gauge plate 2, a plurality of second sliding holes 203 are provided. An upper support component 5 is slidably connected in the side wall of the second sliding hole 203. The upper support component 5 is used to push out the unqualified balance block stuck in the side wall of the stop gauge groove 201 after the inspection is completed.

[0041] The upper support assembly 5 includes several connecting posts 502, which are slidably connected to the side wall of the second sliding hole 203. A support part 501 is welded to the top end face of the connecting post 502. The size of the support part 501 is slightly smaller than the size of the stop gauge groove 201. The support part 501 can slide freely in the stop gauge groove 201, and the thickness of the support part 501 is less than the depth of the stop gauge groove 201, so as not to affect the stop gauge groove 201's detection of the balance block.

[0042] A base 4 is welded to one end face of the stop gauge plate 2 to support the stop gauge plate 2. A first upper support plate 503 is welded to the bottom end face of the connecting column 502. A pair of first sliding grooves 401 matching the first upper support plate 503 are opened on the opposite end face of the base 4. The first upper support plate 503 is slidably connected in the side wall of the first sliding groove 401. A pair of third handles 504 are integrally formed on the opposite end face of the first upper support plate 503.

[0043] like Figure 3 As shown, when not in use, the first upper support plate 503 slides downward under gravity, causing the support part 501 to contact the bottom of the stop gauge groove 201. After the inspection is completed, the first upper support plate 503 is slid upward using the third handle 504, causing the support part 501 to move upward and pushing the balance block upward, so that the balance block protrudes from the top end face of the go gauge plate 1, making it easy to remove the balance block after the inspection is completed.

[0044] like Figure 4As shown, a pair of second fixed posts 402 are integrally formed on one side end face of the base 4. A second upper support assembly 6 is slidably connected to the second fixed posts 402. The projection of the second upper support plate 6 overlaps with the projection of the pair of first upper support plates 503. The second upper support plate 6 can push the pair of first upper support plates 503 to move upward simultaneously. A pair of fourth handles 601 are integrally formed on the opposite end face of the second upper support plate 6. After the test is completed, the second upper support plate 6 is slid upward through the fourth handles 601, pushing the pair of support parts 501 to push the balance block upward simultaneously.

[0045] A bottom support block 403 is welded to one end face of the base 4. The second upper support plate 6 abuts against one end face of the bottom support block 403. The bottom support block 403 supports the second upper support plate 6 so that the second upper support plate 6 does not contact the platform surface when it falls naturally, and can be easily pulled up when used again.

[0046] The groove depth of the GO gauge groove 101 is greater than the thickness of the standard balance block. Multiple scale lines 104 are evenly distributed around the sidewall of the GO gauge groove 101. When the balance block is placed inside the GO gauge groove 101, the thickness of multiple parts of the balance block can be displayed, providing a more accurate reflection of the balance block's thickness. Simultaneously, the scale lines 104 are marked with prominent colors to indicate acceptable areas. This allows for easy identification of whether the balance block's thickness is acceptable during inspection, eliminating the need to determine thickness compliance by reading numerical values.

[0047] The first limiting block 204 is integrally formed on one end face of the stop gauge plate 2, and the first limiting groove 103 matching the first limiting block 204 is opened on one end face of the go gauge plate 1. When the go gauge plate 1 and the stop gauge plate 2 are fixed together by bolts, the first limiting block 204 is engaged in the side wall of the first limiting groove 103, which can better fix the go gauge plate 1. At the same time, it can prevent the go gauge plate 1 from being installed incorrectly or in reverse during installation, so as to avoid the scale line 104 being reversed and affecting the thickness measurement.

[0048] When using, such as Figure 2As shown, before the balance block is placed on the fixture, the spring 210 is in a contracted state, pulling the top end faces of the go gauge part 301 and the no-go gauge part 302 to protrude from the upper surface of the go gauge plate 1. During inspection, the balance block is placed on the fixture, and the balance block contacts the go gauge part 301 to check whether the round hole on the balance block is smaller than the standard. Then, the balance block contacts the no-go gauge part 302 to check whether the round hole on the balance block is larger than the standard value, thereby determining whether the round hole of the balance block is qualified. The balance block continues to move downward, pressing the no-go gauge part 302 downward, while stretching the spring. Then, the balance block enters the go gauge groove 101 to check whether the shape and size of the balance block are larger than the standard. Then, the no-go gauge plate 2 checks whether the shape and size of the balance block are smaller than the standard. At the same time, the thickness of the balance block is visually displayed through the scale line 104 on the side wall of the go gauge groove 101. The thickness value can also be read as needed. After the inspection is completed, the third handle 504 is pulled upward, driving the support part 501 to move upward and push out the balance block, thereby conveniently removing the balance block.
