Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotor seat positioning and sealing technology, and in particular to a copper plate connection hole alignment detection fixture device with anti-misjudgment function. Background Technology
[0002] The copper plate connecting hole alignment detection fixture is a special device used to detect whether the position and size parameters of the copper plate connecting holes meet the standard requirements.
[0003] The existing copper plate connecting hole alignment and inspection fixture device inserts the inspection probe into the inside of the connecting hole to inspect it. It can accurately measure parameters such as the position and diameter of the connecting hole, control the inspection accuracy within a small error range, and improve the accuracy of copper plate production.
[0004] However, in practical applications, existing inspection fixtures typically use inspection probes with a fixed diameter. Inspection is performed by inserting the inspection probe into the inside of the connection hole. However, in such an inspection process, if the diameter of the connection hole is large, the probe can still be placed on the workpiece, making it difficult for workers to detect in time, which is not conducive to improving the inspection accuracy of copper busbars.
[0005] Therefore, this application provides a copper plate connection hole alignment detection fixture device with anti-misjudgment to meet the requirements. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a copper plate connection hole alignment detection fixture device with anti-misjudgment features.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a copper plate connection hole alignment detection fixture device with anti-misjudgment features, comprising:
[0008] A fixture base, wherein a fixing component is provided on the top of the fixture base;
[0009] A false judgment prevention component is provided, which is placed on one side of the fixture base. The false judgment prevention component includes a fixture body disposed on the top of the fixture base. A detection probe is disposed inside the fixture body. The detection probe has a stepped gradient structure, and the diameter of one end of the detection probe is larger than the diameter of the other end.
[0010] Furthermore, a button is fixedly connected to one end of the detection probe away from the fixture body, a limit plate is fixedly connected to one end of the detection probe near the button, and a spring is sleeved on the detection probe, with the spring fixedly connected to the fixture body and the limit plate.
[0011] The beneficial effect of adopting the above-mentioned further solution is that after the detection probe has completed the detection of the workpiece, the button is released, and the spring compressed by the button pushes the detection probe and the button to quickly reset through its own torque, which facilitates subsequent use.
[0012] Furthermore, a bracket is fixedly connected to the side of the fixture body near the detection probe, and the detection probe is slidably connected to the bracket.
[0013] The beneficial effects of adopting the above-mentioned further solutions are: ensuring the stability of the detection probe during use and avoiding deviation of the detection probe when it is moved.
[0014] Furthermore, the fixing assembly includes a clamp that rotates on top of the fixture base, and a connecting plate is fixedly connected to one side of the clamp.
[0015] The beneficial effect of adopting the above-mentioned further solution is that it ensures that the copper plate can be accurately positioned in the preset position when placed on the fixture base, reducing the detection error caused by placement deviation.
[0016] Furthermore, an elastic sleeve is fixedly connected to the side of the connecting plate near the jig base, and a spherical buckle is fixedly connected to the side of the jig base near the elastic sleeve. The connecting plate is engaged with the spherical buckle through the elastic sleeve.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the elastic sleeve is placed on the spherical buckle, and then the opening of the spherical buckle contracts to wrap the spherical buckle, thereby fixing the connecting plate and ensuring the stability of the clamp in use.
[0018] Furthermore, a support plate is fixedly connected to the side of the fixture base near the connecting plate.
[0019] The beneficial effects of adopting the above-mentioned further solution are: ensuring that the fixture does not excessively squeeze the workpiece, while the support plate supports the connecting plate from both sides, ensuring the stability of the connecting plate.
[0020] Furthermore, a rubber pad is fixedly connected to the inner side of the clamp.
[0021] The beneficial effect of adopting the above-mentioned further solution is that it further fixes the workpiece on the fixture base, prevents the fixture from shaking due to environmental factors during the inspection process, and helps to improve the accuracy of the inspection.
[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0023] By setting up an anti-false judgment component, the detection probe is divided into three stages. The end of the detection probe closest to the fixture body is the first stage, and its diameter is consistent with the standard diameter of the connecting hole. The diameter of the second stage is set to match the minimum allowable error of the connecting hole. The end furthest from the fixture body is the third stage, and its diameter is equal to the maximum allowable error value of the connecting hole. In actual testing, the detection probe is inserted into the copper plate connecting hole of the fixture body. By observing how the detection probe passes through the connecting hole, it can be determined whether the actual diameter of the connecting hole is qualified. If only the first stage can pass through the connecting hole smoothly, it means that the diameter of the copper plate connecting hole fully meets the production standard. If the second stage can also pass through the connecting hole, it means that although there is a certain error in the diameter of the connecting hole, it is still within the allowable error range. If the third stage can pass through the connecting hole, it means that the diameter of the copper plate connecting hole has exceeded the allowable range, and this copper plate does not meet the production standard. In this way, it is possible to quickly determine whether the copper plate is qualified, effectively avoid possible errors in the testing process, and improve the accuracy of the testing.

[0032] 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.
[0033] like Figures 1-4 As shown, this utility model provides a technical solution: a copper plate connection hole alignment detection fixture device with anti-misjudgment, including: fixture base 1, and a fixing component 3 is provided on the top of the fixture base 1;
[0034] like Figures 1-3 As shown, the anti-false judgment component 2 is placed on one side of the fixture base 1. The anti-false judgment component 2 includes a fixture body 21 set on the top of the fixture base 1. A detection probe 22 is set inside the fixture body 21. The detection probe 22 has a stepped gradient structure, with the diameter of one end of the detection probe 22 being larger than the diameter of the other end. By setting the detection probe 22 into three stages, the end closer to the fixture body 21 is the first stage, and its diameter matches the diameter of the connecting hole. The diameter of the second stage of the detection probe 22 matches the minimum allowable error of the connecting hole. The end of the detection probe 22 away from the fixture body 21 is the third stage. The diameter is equal to the maximum error of the connecting hole. The detection probe 22 is inserted into the copper plate connecting hole on the fixture body 21. The diameter of the connecting hole is determined according to the passage of the detection probe 22 through the connecting hole. If only the first segment can pass through the connecting hole, the diameter of the copper plate connecting hole meets the production standard. If the second segment can pass through the connecting hole, the diameter of the copper plate connecting hole is within the allowable error range. If the third segment can pass through the connecting hole, the diameter of the copper plate connecting hole exceeds the allowable range, and it is determined that the copper plate does not meet the production standard. This allows for a quick determination of whether the copper plate meets the production standard and avoids detection errors, which helps to improve the accuracy of the detection.
[0035] Furthermore, such as Figure 3 As shown, a button 23 is fixedly connected to one end of the detection probe 22 away from the fixture body 21, and a limiting plate 26 is fixedly connected to one end of the detection probe 22 near the button 23. A spring 24 is sleeved on the detection probe 22, and the spring 24 is fixedly connected to the fixture body 21 and the limiting plate 26. By pressing the button 23, the button 23 pushes the detection probe 22 toward the workpiece on the fixture body 21 and compresses the spring 24. When the detection probe 22 has completed the detection of the workpiece, the button 23 is released, and the spring 24 compressed by the button 23 pushes the detection probe 22 and the button 23 to quickly reset through its own torque, which facilitates subsequent use.
[0036] Furthermore, such as Figure 3As shown, a bracket 25 is fixedly connected to the side of the fixture body 21 near the detection probe 22. The detection probe 22 is slidably connected to the bracket 25. By installing the bracket 25 between the fixture body 21 and the detection probe 22, the bracket 25 can support the movement of the detection probe 22 and the button 23, ensuring the stability of the detection probe 22 in use and preventing the detection probe 22 from shifting when moving.
[0037] Furthermore, such as Figure 4 As shown, the fixing component 3 includes a clamp 31 that rotates on the top of the fixture base 1. A connecting plate 32 is fixedly connected to one side of the clamp 31. The clamp 31 is rotated on the fixture base 1 by a conventional hinge. The clamp 31 is used to hold the workpiece on the fixture base 1, keeping the fixture base 1 fixed. This ensures that when the copper plate is placed on the fixture base 1, it can be accurately positioned in the preset position, reducing the detection error caused by placement deviation. At the same time, the connecting plate 32 connects the two clamps 31, thereby reducing the number of times the clamps 31 are used to fix the workpiece.
[0038] Furthermore, such as Figure 4 As shown, an elastic sleeve 33 is fixedly connected to the side of the connecting plate 32 near the jig base 1, and a spherical buckle 34 is fixedly connected to the side of the jig base 1 near the elastic sleeve 33. The connecting plate 32 is engaged with the spherical buckle 34 through the elastic sleeve 33. When the connecting plate 32 is pushed, the elastic sleeve 33 contacts the spherical buckle 34. Due to the elasticity of the elastic sleeve 33, the spherical buckle 34 pushes the opening of the elastic sleeve 33 to expand outward. When the opening diameter of the elastic sleeve 33 is larger than the diameter of the spherical buckle 34, the connecting plate 32 continues to move downward, putting the elastic sleeve 33 onto the spherical buckle 34. Then, the opening of the spherical buckle 34 contracts to wrap around the spherical buckle 34, thereby fixing the connecting plate 32 and ensuring the stability of the fixture 31 in use.
[0039] Furthermore, such as Figure 4 As shown, a support plate 35 is fixedly connected to the jig base 1 on the side near the connecting plate 32. By installing the support plate 35, the support plate 35 limits the maximum moving distance of the jig 31, ensuring that the jig 31 will not excessively squeeze the workpiece. At the same time, the support plate 35 supports the connecting plate 32 from both sides, ensuring the stability of the connecting plate 32.
[0040] Furthermore, such as Figure 4 As shown, a rubber pad 36 is fixedly connected to the inner side of the fixture 31. By using the rubber pad 36, additional friction and buffer space are provided between the fixture 31 and the workpiece, so that the fixture 31 can further fix the workpiece on the fixture base 1, preventing the fixture 31 from shaking due to environmental factors during the inspection process, which is beneficial to improving the accuracy of the inspection.
[0041] Working principle: such as Figures 1-4As shown, the bronze workpiece is first placed on the fixture base 1 and fixed on the fixture body 21. Then, the clamp 31 is pushed and rotated along the hinge to the top of the workpiece, causing the rubber pad 36 to press against the fixture base 1. When the elastic sleeve 33 contacts the spherical buckle 34, the spherical buckle 34 pushes the opening of the elastic sleeve 33 to expand outward. When the opening diameter of the elastic sleeve 33 is larger than the diameter of the spherical buckle 34, the connecting plate 32 continues to move downward, fitting the elastic sleeve 33 onto the spherical buckle 34, and the support plate 35 supports the connecting plate 32 from both sides. Next, the button 23 is pressed, which pushes the detection probe 22 inside the bracket 25 towards the workpiece on the fixture body 21 and squeezes it. The spring 24 is compressed, and the detection probe 22 is inserted into the copper plate connection hole. The diameter of the connection hole is judged according to the insertion of the detection probe 22. If only the first segment can pass through the connection hole, the diameter of the copper plate connection hole meets the production standard. If the second segment can pass through the connection hole, the diameter of the copper plate connection hole is within the allowable error range. If the third segment can pass through the connection hole, the diameter of the copper plate connection hole exceeds the allowable range, and the copper plate is judged to not meet the production standard. This avoids detection errors and helps improve the accuracy of detection. Finally, the button 23 is released. The spring 24 compressed by the button 23 pushes the detection probe 22 and the button 23 to quickly reset through its own torque, which facilitates subsequent use.
[0042] 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.
