Description
Technical Field
[0001] This utility model relates to the technical field of sheet metal testing equipment, and in particular to an auxiliary measuring device for ear-making rate. Background Technology
[0002] After a circular sheet metal undergoes a cup-making test, the uneven bumps and depressions appearing at the edge of the cup are called lugs. Analyzing the lugs on sheet metal parts can evaluate the anisotropy of the sheet metal in the plane. Chinese Utility Model Patent (Authorization Announcement No.: CN209445949U) discloses an auxiliary measuring device for the lug rate of sheet metal. This auxiliary measuring device for the lug rate of sheet metal includes a vertical axis, a vertical height adjustment device, a horizontal axis, a horizontal position adjustment device, a dial indicator, a rotatable base, and multiple circular trays with different inner diameters. By positioning the circular trays on the rotatable base and aligning them with the dial indicator probe, the lug rate of sheet metal can be easily detected.
[0003] In this technical solution, a U-shaped retaining edge that matches the side wall of a circular tray is fitted onto the dial indicator probe to facilitate positioning close to the circular tray during measurement, ensuring that the probe aligns with the upper edge of the circular cup. However, in actual use, because the circular cup is fixed inside the circular tray by multiple screws, it is difficult for the cup and the circular tray to achieve a coaxial alignment during manual operation. This causes the edge of the cup to wobble within the U-shaped retaining edge when the circular tray rotates. This not only causes the circular tray to jam, affecting the measurement process, but the wobble force acting on the dial indicator also leads to errors in the measured values, thus affecting the accuracy of the measurement.

[0008] The detection assembly includes a dial indicator and a limiting seat. The dial indicator is mounted on the mounting bracket, and the limiting seat is mounted on the measuring head of the dial indicator and is provided with a limiting groove. The edge of the circular cup can be accommodated within the limiting groove.

[0013] In an optional embodiment, the placement base further includes a fixing magnetic element that can magnetically engage with the second base body to press the round cup onto the surface of the second base body.
[0014] In an optional embodiment, the surface of the second base is recessed to form a plurality of marking grooves, and the plurality of marking grooves are arranged concentrically.
[0015] In an optional embodiment, the limiting seat includes a third seat body and a stop post. The third seat body is connected to the measuring head of the dial indicator and forms the limiting groove. The stop post is rotatably connected to the limiting groove, and the edge of the round cup can abut against the surface of the stop post.
[0016] In an optional embodiment, the mounting bracket includes a transverse mounting rod, a longitudinal mounting rod, and an adjusting seat. The adjusting seat has a first mounting hole and a second mounting hole. The longitudinal mounting rod is fixedly connected to the base and passes through the first mounting hole.

[0019] This utility model discloses an auxiliary measuring device for ear-making rate, used to detect round cups. The auxiliary measuring device for ear-making rate includes:
[0020] The base and mounting bracket are connected to the base. The dial indicator of the detection component is mounted on the mounting bracket. The limit seat is mounted on the measuring head of the dial indicator and is provided with a limit groove. During the detection process, the edge of the round cup can be accommodated in the limit groove.

The placement seat is rotatably connected to the mounting base, and the round cup is detachably connected to the placement seat.
[0021] In one embodiment, the round cup to be tested is fixed on the placement base. A dial indicator is moved so that the edge of the cup is accommodated within the limiting groove, with the edge abutting against the bottom wall of the groove. The dial indicator is zeroed, and the placement base is rotated, allowing the edge to continuously abut against the bottom wall of the limiting groove. The corresponding reading is obtained from the dial indicator reading, and the ear-tightening rate of the round cup is then calculated. In this application, when the center of the round cup to be tested does not coincide with the center of the placement base (i.e., they are not coaxial), the mounting base connected to it can slide relative to the base in the limiting direction of the limiting groove when the placement base is rotated. This prevents the round cup from getting stuck during rotation. Furthermore, the sliding placement base ensures that the edge of the round cup is always well accommodated within the limiting groove, thus avoiding excessive force between the edge and the side wall of the limiting groove. This results in a more accurate dial indicator reading and higher accuracy in detecting the ear-tightening rate. Attached Figure Description

[0034] Reference Figures 1 to 4 This utility model proposes an auxiliary measuring device 100 for ear-making rate.
[0035] In this embodiment of the invention, the ear-forming rate auxiliary measuring device 100 is used to detect the round cup 200, which is formed from a metal sheet through stretching and cutting processes. The ear-forming rate auxiliary measuring device 100 is mainly used to detect the unevenness and irregularity of the edges of the round cup 200. That is, by detecting the difference in edge height, the ear-forming rate of the sheet metal is calculated using a formula, thereby obtaining the anisotropy of the sheet metal in the plane of the sheet. The measurement and calculation of the ear-forming rate of the sheet metal is prior art and will not be described in detail here.
[0036] In this application, to accurately measure the drop of the edge of the round cup 200, the ear-making rate auxiliary measuring device 100 includes: a base 10; a mounting frame 20 connected to the base 10; a detection component 30, including a dial indicator 31 and a limiting seat 32, wherein the dial indicator 31 is mounted on the mounting frame 20, the limiting seat 32 is mounted on the measuring head of the dial indicator 31 and is provided with a limiting groove 32a, and the edge of the round cup 200 can be accommodated in the limiting groove 32a; and a placement component 40, including a placement seat 41 and a mounting seat 42, wherein the mounting seat 42 is connected to the base 10 and can slide along the limiting direction of the limiting groove 32a, the placement seat 41 is rotatably connected to the mounting seat 42, and the round cup 200 is detachably connected to the placement seat 41.
[0037] Specifically, the mounting bracket 20 includes a horizontal mounting rod 21, a vertical mounting rod 22, and an adjusting seat 23 made of metal or plastic. The adjusting seat 23 has a first mounting hole (not shown) and a second mounting hole (not shown) with the same diameter as the horizontal mounting rod 21 and the vertical mounting rod 22. One end of the vertical mounting rod 22 is fixedly connected to the base 10 and extends vertically. The vertical mounting rod 22 passes through the first mounting hole, connecting the adjusting seat 23 and the vertical mounting rod 22. The horizontal mounting rod 21 passes through the second mounting hole, connecting it to the adjusting seat 23. A dial indicator 31 is mounted on the end of the horizontal mounting rod 21 away from the vertical mounting rod 22. Under external force, the adjusting seat 23 can move up and down relative to the vertical mounting rod 22, and the horizontal mounting rod 21 can reciprocate horizontally relative to the adjusting seat 23, thus adjusting the position of the dial indicator 31.
[0038] Furthermore, the mounting bracket 20 also includes a first adjusting knob 24 and a second adjusting knob 25. The adjusting seat 23 has a first threaded adjusting hole and a second threaded adjusting hole respectively communicating with the first mounting hole and the second mounting hole. The ends of the first adjusting knob 24 and the second adjusting knob 25 are provided with external threads that are compatible with the first threaded adjusting hole and the second threaded adjusting hole. The first adjusting knob 24 is screwed into the first threaded adjusting hole and abuts against the surface of the longitudinal mounting rod 22. The second adjusting knob 25 is screwed into the second threaded adjusting hole and abuts against the surface of the transverse mounting rod 21. This application can greatly facilitate the position adjustment of the dial indicator 31 by setting the first adjusting knob 24 and the second adjusting knob 25.
[0039] In one embodiment, the round cup 200 to be tested is fixed on the placement seat 41. The dial indicator 31 is moved so that the edge of the round cup 200 is accommodated in the limiting groove 32a and the edge abuts against the bottom wall of the limiting groove 32a. The dial indicator 31 is adjusted to zero. The placement seat 41 is rotated so that the edge continues to abut against the bottom wall of the limiting groove 32a. The corresponding reading is found through the reading of the dial indicator 31, and then the ear-making rate of the round cup 200 is calculated. In this application, the round cup 200 to be tested is placed on the placement seat 41. When its center does not coincide with the center of the placement seat 41, that is, when the two are not coaxially set, when the placement seat 41 is rotated, the mounting seat 42 connected to it can slide relative to the base 10 in the limiting direction of the limiting groove 32a. This avoids the round cup 200 from getting stuck when rotating. In addition, the sliding placement seat 41 allows the edge of the round cup 200 to always be well contained in the limiting groove 32a, thereby avoiding the situation where the edge and the side wall of the limiting groove 32a have a large force. The reading of the dial gauge 31 is more accurate, and the detection accuracy of the ear-making rate is higher.
[0040] Please see again Figure 4 In this embodiment, the base 10 has a limiting groove 10a, which is a stepped groove. The limiting groove 10a extends along the limiting direction of the limiting groove 32a, which is the length direction of the limiting groove 32a. The mounting base 42 includes a first base body 421 and a sliding limiting post 422 connected to the first base body 421. The sliding limiting post 422 and the first base body 421 are threadedly connected. The placement base 41 is rotatably connected to the first base body 421, and the sliding limiting post 422 is slidably embedded in the limiting groove 10a. By setting the sliding limiting post 422, the first base body 421 can be limited to the surface of the base 10 while sliding. At the same time, the threaded connection between the first base body 421 and the sliding limiting post 422 facilitates disassembly and assembly.
[0041] In this application, the placement seat 41 includes a second seat body 411 connected to a rotating flange 412. The surface of the first seat body 421 facing away from the base 10 is recessed to form a rotating connection groove 421a. The transfer flange and the transfer connection groove extend in an annular shape. The rotating flange 412 is rotatably fitted into the rotating connection groove 421a, thereby realizing the rotating connection between the second seat body 411 and the first seat body 421.
[0042] Please see again Figure 4The placement base 41 also includes a fixing magnetic component 413, which can be magnetically attracted to the second base 411. The fixing magnetic component 413 can be a magnet or a metal that can be magnetically attracted, such as iron or steel. That is, one of the fixing magnetic component 413 and the second base 411 is a magnet, and the other is a magnetically attracting metal, or both are magnets. When the round cup 200 is placed on the surface of the second base 411, the fixing magnetic component 413 can be placed inside the round cup 200, pressing the round cup 200 against the surface of the second base 411 by magnetic force. This simplifies the assembly and disassembly of the round cup 200.
[0043] Furthermore, the surface of the second base 411 is recessed with a plurality of marking grooves 411a, which are circular and concentrically arranged. The diameter of the marking grooves 411a can be set to 30mm, 40mm, 55mm, etc., and the marking grooves 411a are used to assist the operator in coaxially positioning the round cup 200 and the second base 411.
[0044] In this embodiment, the limiting seat 32 includes a third seat body 321 and abutment post 322. The third seat body 321 is generally U-shaped. The third seat body 321 is connected to the measuring head of the dial indicator 31 and forms the aforementioned limiting groove 32a. The third seat body 321 has a connecting shaft with the same diameter as the abutment post 322. The abutment post 322 is sleeved on the connecting shaft. The edge of the round cup 200 can abut against the surface of the abutment post 322. When the round cup 200 rotates, the abutment post 322 can rotate relative to the third seat body 321 under the action of friction, which makes the detection of the ear restraint rate of the round cup 200 smoother.
[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
