Abstract
Description
Technical Field
[0001] This utility model relates to the field of arc measuring devices, and in particular to a sliding arc measuring seat. Background Technology
[0002] The base plate used in the power rectifier module is a flat plate. Due to the requirements of subsequent processes, the base plate needs to have a pre-deformed arc. The position and size of this deformation arc must meet the process requirements. Therefore, it is necessary to measure the positioning of the pre-deformed arc of the power rectifier module base plate. Only after the measurement is qualified can it proceed to the next process.
[0003] Existing power rectifier module base plate pre-deformation arc positioning and measuring devices include a dial indicator, which is fixed at the center of the arc measuring and positioning device. The surface of the arc measuring and positioning device has a concave groove to facilitate standard positioning and measurement of base plates of different lengths. The arc measuring and positioning device can be fixed on a bracket, as shown in the patent with authorization announcement number CN206656681U. During measurement, the dial indicator is turned on, and when the module base plate is in place, a locking strip is inserted into the positioning slot. The module base plate is then placed on the arc measuring and positioning device, and the pre-deformation arc can be read on the dial indicator. In addition, placing the arc measuring and positioning device on a bracket facilitates large-scale measurement and reading. However, the insertion and removal operation between the locking strip and the positioning slot in the existing arc positioning and measuring device is inconvenient, especially since the arc of a base plate needs to be detected in both the length and width directions. The high frequency of changing the locking strip position reduces the measurement efficiency. Therefore, a convenient sliding arc measuring base is needed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a sliding arc measuring seat.
[0005] To solve the above problems, the present invention adopts the following solution: A sliding arc measuring base includes a dial indicator, a positioning component, and a slider. The positioning component is an elongated strip in the shape of an "I". A downwardly recessed portion is provided in the middle of the positioning component, and a dial indicator is fixedly mounted in the recessed portion, with the measuring end of the dial indicator exposed on the upper part of the positioning component. The upper surface of the positioning component is also provided with a sliding groove that cooperates with the slider, and the sliding groove is located on both sides of the dial indicator. Two sliders are provided on each side of the dial indicator, and both sliders are slidably mounted in the sliding groove. The two sliders are used to clamp the edge of the object being measured.
[0006] Furthermore, the slide is an inverted "T" shaped groove, and the bottom of the slider is provided with an inverted "T" shaped structure that matches the slide.
[0007] Furthermore, the slider and the groove are fixed together by locking screws.
[0008] Furthermore, the locking screw passes through the slider from above and abuts against the slide groove to achieve positioning.
[0009] Furthermore, one end of the locking screw is configured with a threaded structure, and the other end is configured with a larger diameter cylinder, with anti-slip texture on the outer side of the cylinder.
[0010] Furthermore, the upper surface of the slider is provided with a protruding stepped block, which is used to abut against the side of the object being measured.
[0011] Furthermore, the positioning element is also provided with scale lines; the scale lines are provided on the positioning element and located below the slider on the positioning element; the arrangement direction of the scale lines is consistent with the length direction of the slide groove.
[0012] Furthermore, the scale line is located on one or both sides of the positioning member.
[0013] Furthermore, the positioning member has a through hole in the middle for the dial indicator to pass through, and a bolt for fastening is provided on the side of the through hole.
[0014] Furthermore, it also includes a base; the base is generally square plate-shaped, with upward-extending support members on both sides of the base, and a support block corresponding to the support member on the lower surface of the positioning member; the support block abuts against the groove on the upper end face of the support member to achieve positioning support.
[0015] The beneficial effects of this utility model are as follows: By setting up an adjustable slider, along with a dial indicator and other structures, the curvature of the base plate under test can be detected, and the spacing of the slider can be easily adjusted, making the operation convenient. By setting locking screws, the position between the slider and the slide groove is locked, ensuring that the square base plate being tested slides in a straight line during sliding detection without any offset.

[0018] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0020] Example 1: like Figures 1-3 As shown, a sliding arc measuring base includes a dial indicator 1, a positioning component 2, and a slider 3. The positioning component 2 is generally a long strip in the shape of an "I". A downwardly recessed portion is provided in the middle of the positioning component 2, and the dial indicator 1 is fixedly mounted in this recessed portion. The dial of the dial indicator 1 is located below the positioning component 2, and the measuring end of the dial indicator 1 passes through the positioning component 2, protruding from its upper part. The upper surface of the positioning component 2 also has sliding grooves 5 that cooperate with the slider 3, located on both sides of the dial indicator 1. Two sliders 3 are respectively provided on both sides of the dial indicator 1, and both sliders 3 are slidably positioned within the sliding grooves 5. The two sliders 3 are used to clamp the edge of the object being measured. During testing, the object being measured is pressed against the measuring end of the dial indicator 1 between the two sliders 3 and slid. In this example, this is the base plate of the rectifier module. By observing the change in the value of the dial indicator 1, the arc of the base 8 can be obtained.
[0021] The slide groove 5 is an inverted "T" shaped groove, and the bottom of the slider 3 is provided with an inverted "T" shaped structure that matches the slide groove 5. The clearance tolerance between the "T" shaped grooves is small, which gives the slider 3 a certain resistance when sliding in the slide groove 5, facilitating the sliding of the measured base 8 between the two sliders 3. The slider 3 and the slide groove 5 are fixed together by a locking screw 6. The locking screw 6 passes through the slider 3 from above and abuts against the slide groove 5 for positioning. In this example, one end of the locking screw 6 is a threaded structure, and the other end is a column with a larger diameter, and the outer side of the column is provided with anti-slip texture. This ensures that the slider 3 is fixed to the slide groove 5, ensuring that the slider 3 will not shift during measurement and affect the arc measurement result. It should be noted that in order to match base plates of different sizes, multiple sizes of sliders 3 can be provided, with different lengths of sliders 3, because the range of motion of sliders 3 of different sizes in the slide groove 5 is different.
[0022] The upper surface of the slider 3 is provided with a protruding stepped block 4, which is used to abut against the side of the object being measured. It should be noted that the stepped block 4 is located at the end of the upper surface of the slider 3 away from the dial indicator 1. In this way, the side of the upper surface of the slider 3 near the dial indicator 1 is flat, which makes it easy to fit the bottom surface of the base plate being measured. After the edge of the square base 8 being measured abuts against the stepped block 4 on the slider 3, it can maintain sliding in a straight direction.
[0023] The positioning element 2 is also provided with a scale line 11; the scale line 11 is located on the positioning element 2, below the slider 3 on the positioning element 2; the arrangement direction of the scale line 11 is consistent with the length direction of the slide groove 5; in this example, the scale line 11 is located on one or both sides of the positioning element 2; it should be noted that in some other embodiments, the scale line 11 can also be located on the upper surface of the positioning element 2. By observing the scale line 11, the sliders 3 on both sides can be adjusted to achieve symmetrical arrangement with respect to the dial indicator 1 in the middle, so that the detection end of the dial indicator 1 slides along the middle part of the base plate being measured to detect the curvature of the middle part.
[0024] The positioning component 2 has a through hole in the middle for the dial indicator 1 to pass through the detection end. A bolt 7 for fastening is provided on the side of the through hole. In this example, an internal hex bolt 7 is used to facilitate the adjustment of the height of the dial indicator 1 and control the length of the exposed part of its detection end.
[0025] It also includes a base 8; the base 8 is generally square plate-shaped, and there are upward-extending support members 9 on both sides of the base 8. A support block 10 corresponding to the support member 9 is provided on the lower surface of the positioning member 2. The support block 10 is integrally formed with the positioning member 2. The support block 10 abuts in the groove on the upper end surface of the support member 9 to achieve positioning support, which facilitates the curvature measurement of a large number of base plates to be measured.
[0026] During implementation, by setting up a sliding adjustable slider 3, in conjunction with a dial indicator 1 and other structures, the curvature of the base plate under test can be detected, and the spacing of the slider 3 can be easily adjusted, making the operation convenient. By setting a locking screw 6, the position between the slider 3 and the slide groove 5 is locked, ensuring that the square base plate under test slides in a straight line during sliding test without deviation. By setting a scale line 11, the sliders 3 on both sides of the dial indicator 1 are controlled to be symmetrical, and the middle part of the base plate between them is controlled to contact the detection end of the dial indicator 1, ensuring accurate detection.
[0027] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
