Description

TECHNICAL FIELD

[0001] The present application relates to the field of detection devices, in particular to a high-efficiency detection device for detecting the height value of a workpiece. BACKGROUND

[0002] In order to improve the efficiency of inspecting workpieces in batch production, the inspection department will make special gauges for the sizes to be inspected on the workpieces in order to inspect the workpieces to be inspected. Whether the size of the workpiece is qualified is determined according to the fitting condition of the workpiece to be inspected and the gauge. When it is necessary to inspect whether the height difference between the surface of the workpiece to be inspected and the bottom surface of the workpiece is qualified, in order to avoid the problem that manual measurement by a caliper is prone to error, the inspection department will customize the corresponding gauge according to the size and shape of the place to be inspected. During inspection, the workpiece is first positioned on the placement position of the inspection table, and then the gauge is pressed tightly on the place to be inspected on the upper surface of the workpiece. If the gauge cannot be pressed into place, the height difference between the inspection place on the upper surface of the workpiece and the bottom surface of the workpiece is higher than the upper limit of the qualified height difference, and the workpiece is unqualified. The workpiece to be inspected can only enter the next inspection process under the condition that the gauge can be pressed into place.

[0003] A Chinese patent with application number CN201921917291.5 discloses a middle-load type turnover mechanism for an automobile stamping part gauge, which comprises a base, fixing holes, a turnover seat, limiting locking bolts and a pressing plate. The base is a rectangular block, and fixing holes are formed on both sides of the base. Multiple fixing holes are arranged. The turnover seat is vertically welded to the upper end of the base. Two limiting locking bolts are arranged, one end of each limiting locking bolt is provided with a pattern knob, and the limiting locking bolts are connected with the turnover seat through threads. The pressing plate is clamped in the turnover seat and is connected by sliding. This scheme determines whether the distance between the surface to be measured of the workpiece pressed by the pressing plate and the bottom surface of the workpiece exceeds the upper limit by whether the pressing plate can be fixed in the fixing hole at the corresponding height of the turnover seat. If it cannot be pressed, the distance between the surface to be measured of the workpiece and the bottom surface of the workpiece exceeds the upper limit, and the size of the workpiece is unqualified. However, this scheme needs to disassemble and assemble the pressing plate every time for inspection, which is complicated to operate and time-consuming. SUMMARY

[0004] The present application proposes a high-efficiency detection device for detecting the height value of a workpiece, which is simple in structure and convenient to use.

[0005] The present application is realized by the following technical solutions:

[0006] The utility model provides a kind of high-efficiency detection device for workpiece height value detection, including detection table, the detection table is equipped with for placing workpiece placement station and the height value of the detection assembly for detecting the top of workpiece the height of the face to be detected, the detection assembly includes the base connected to detection table, with the connecting rod of base rotation, and installation is detected in connecting rod;The connecting rod is equipped with mobile piece that can be transversely moved relative to connecting rod, and the height measuring piece for detecting whether mobile piece is at specified height position is installed on the base with mobile piece cooperation.

[0007] The utility model discloses a kind of high-efficiency detection device for workpiece height value detection, whether the height difference between the top of workpiece the face to be detected to workpiece bottom surface can be detected higher than the upper limit of qualified range, the utility model is convenient for inspection, after rotating connecting rod to the detection of workpiece is qualified when mobile piece is at specified height position after the detection tool mounted on connecting rod is pressed on the top of workpiece the face to be detected, if mobile piece is not at specified height position, then the detection of workpiece is unqualified.Compared with prior art pressing plate and base detachable connection, it needs to be first removed before each test Pressing plate, when testing, first press the pressing plate on the face to be detected, if the pressing plate can be installed at the specified height of base after pressing, the detection of workpiece is qualified, if the pressing plate cannot be installed at the specified position of base after pressing, then the test is unqualified, the connecting rod of the utility model is rotatably connected to the base with the detection tool mounted, and it is more convenient to operate without disassembling connecting rod during testing.Specifically, height measuring piece can select the measuring plate including qualified range line.

[0008] As preferred, the height measuring piece includes a height measuring hole for inserting the mobile piece at the specified height.

[0009] Therefore, during testing, rotate the connecting rod to press the detection tool of detection assembly on the workpiece, move the mobile piece towards the height measuring hole, and the mobile piece of detection assembly pressed on the qualified workpiece is located within the insertion range of the height measuring hole;The mobile piece of detection assembly pressed on the unqualified workpiece exceeds the insertion range of the height measuring hole, and the detection result can be obtained intuitively and quickly according to whether the mobile piece can be inserted into the height measuring hole.

[0010] As preferred, the height measuring piece includes a height measuring plate for pressing the mobile piece at the specified height.

[0011] The preferred height measuring piece includes a height measuring plate for pressing the mobile piece at the specified height, so that, during testing, after rotating the connecting rod to press the detection tool on the workpiece, move the mobile piece towards the height measuring plate, if the mobile piece can be moved below the height measuring plate to be pressed by the height measuring plate, the test is qualified, if not, the test is unqualified. Therefore, after pressing the detection tool on the workpiece, move the mobile piece, and the detection result can be obtained intuitively and quickly according to whether the mobile piece can be moved below the height measuring plate.

[0012] As a preferred, the base comprises a limiting support part for limiting the maximum downward rotation range of the connecting rod.

[0013] The preferred can avoid the situation that the gauge is pressed to damage the qualified workpiece when the connecting rod excessively rotates downward during the detection.

[0014] As a preferred, the gauge comprises a clamping opening for clamping the surface to be detected of the workpiece.

[0015] Therefore, when there are multiple concave-convex structures on the surface to be detected, the gauge can clamp the concave-convex structures on the surface to be detected through the clamping opening. After clamping, if the moving part can be located at the specified height position, the height of each concave-convex structure on the surface to be detected is also qualified. If the moving part cannot be located at the specified height position, the surface to be detected must have a place that is unqualified, so that it can be determined that the workpiece is unqualified. Therefore, the preferred can avoid the situation that the cost is increased due to the need to separately provide a gauge and separately perform detection for each concave-convex structure on the surface to be detected.

[0016] As a preferred, the base comprises two limiting plates, the connecting rod is located between the two limiting plates, and the side of the limiting plate facing the connecting rod is provided with a limiting column for abutting against the side of the connecting rod.

[0017] The preferred limiting plate has a limiting column on the side facing the connecting rod for abutting against the side of the connecting rod. Therefore, the preferred can limit the left-right shaking of the connecting rod, so as to avoid the situation that when there are multiple concave-convex structures on the surface to be detected, the clamping opening of the gauge needs to be accurately clamped on the corresponding concave-convex structure on the surface to be detected to complete the detection, but the connecting rod lacking the abutment of the limiting column is prone to left-right shaking, which makes it difficult to accurately clamp the clamping opening.

[0018] As a preferred, the detection assembly further comprises a handle detachably connected to the moving part; the connecting rod comprises a moving groove and a handle groove; the moving part is located in the moving groove, and the handle is located in the handle groove.

[0019] The preferred detection assembly further comprises a handle detachably connected to the moving part. Therefore, the detector can move the moving part by operating the handle. The connecting rod comprises a moving groove and a handle groove, the moving part is located in the moving groove, and the handle is located in the handle groove. Therefore, the handle located in the handle groove can only move in the handle groove, so as to limit the movement range of the moving part connected to the handle, and avoid the over-removal of the moving part from the connecting rod. The handle is detachably connected to the moving part. Therefore, the handle and the moving part can be disassembled and replaced after the moving part is worn out.

[0020] As a preferred, the moving part is connected to the side of the connecting rod through a spring.

[0021] Therefore, during the detection, the moving part can be translated by the spring without manual movement to complete the detection.

[0022] Preferably, the base includes a replacement part and a connecting part. The connecting rod, the height measuring component, and the limiting support are respectively disposed in the connecting part. The connecting part is detachably connected to the replacement part. The replacement part is detachably connected to the testing table. The inspection tool and the moving component are detachably connected to the connecting rod.

[0023] Therefore, by replacing different types of gauges, replacement parts of different heights, or connecting rods of different lengths, different workpieces can be inspected.

[0024] Preferably, the height measuring component is detachably connected to the connecting part.

[0025] Therefore, when the height measuring component wears out due to excessive use, this feature facilitates the replacement of the height measuring component, thus avoiding the situation where wear of the height measuring component affects the accuracy of the test results.

[0026] The present invention has the following beneficial effects:

[0027] 1. This invention is easy to operate. During inspection, the connecting rod is rotated until the inspection fixture installed on the connecting rod presses against the inspection surface on the top of the workpiece. If the moving part is at the specified height position, the workpiece is qualified. If the moving part is not at the specified height position, the workpiece is unqualified.

[0028] 2. The inspection fixture of the present invention includes an engagement opening for engaging with the surface of the workpiece to be inspected. Therefore, when there are multiple uneven structures on the surface to be inspected, the height of each uneven structure can be inspected through the engagement opening. After engagement, if the moving part can be positioned at the specified height, the height of each uneven structure on the surface to be inspected is also qualified; if the moving part cannot be positioned at the specified height, there must be one unqualified part on the surface to be inspected, thus determining that the workpiece is unqualified.

[0029] 3. This invention includes a limiting post for abutting the side of the connecting rod, which helps to limit the left and right swaying of the connecting rod. This avoids the situation where, when there are multiple concave and convex structures on the surface to be inspected, the clamping jaws of the inspection tool need to accurately engage with the corresponding concave and convex structures on the surface to be inspected in order to complete the inspection. However, without the limiting post to abut, the connecting rod is prone to left and right swaying, making it difficult for the clamping jaws to engage accurately.

[0030] 4. The base of the present invention includes a replacement part and a connecting part. The connecting rod, height measuring component, and limiting support are respectively disposed in the connecting part. The connecting part is detachably connected to the replacement part, and the replacement part is detachably connected to the inspection table. The inspection fixture and the moving component are respectively detachably connected to the connecting rod. Therefore, the present invention can be used to inspect different workpieces by replacing different types of inspection fixtures, replacement parts of different heights, or connecting rods of different lengths.

Detailed Implementation

[0035] The following specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0036] like Figure 1 As shown, a high-efficiency detection device for detecting the height value of a workpiece includes a detection table 5. The detection table 5 is provided with a placement station for placing a workpiece 4 and a detection assembly for detecting the height value of the top surface of the workpiece 4 to be inspected. The detection assembly includes a base 1 connected to the detection table 5, a connecting rod 2 rotatably connected to the base 1, and a gauge 3 installed on the connecting rod 2. The connecting rod 2 is provided with a movable component 6 that can move laterally relative to the connecting rod 2. The base 1 is equipped with a height measuring component 7 that cooperates with the movable component 6 and is used to detect whether the movable component 6 is at a specified height position.

[0037] The inspection fixture 3 includes an engagement opening 31 for engaging with the surface of the workpiece 4 to be inspected. Thus, when there are multiple uneven structures on the surface to be inspected, the inspection fixture 3 can engage with these structures through the engagement opening 31. After engagement, if the moving part 6 is positioned at a specified height, the height of each uneven structure on the surface to be inspected is also acceptable; if the moving part 6 cannot be positioned at the specified height, one part of the surface to be inspected will necessarily be unacceptable, thus determining that the workpiece 4 is unacceptable. Therefore, this preferred design helps avoid the increased cost associated with equipping a separate inspection fixture and performing separate inspections for each uneven structure on the surface to be inspected.

[0038] Further, to avoid the situation that the left and right shaking of the connecting rod 2 makes it difficult for the occlusal surface 31 to accurately occlude the surface to be detected with multiple concave-convex structures, the base 1 comprises two limiting plates 12, the connecting rod 2 is located between the two limiting plates 12, and the side of the limiting plate 12 facing the connecting rod 2 is provided with a limiting column 121 for abutting the side surface of the connecting rod 2. Thus, the limiting column 121 can limit the left and right shaking of the connecting rod 2.

[0039] To avoid the situation that the excessive downward rotation of the connecting rod 2 during detection causes the gauge 3 to be pressed and damaged on the qualified workpiece 4, the base 1 comprises a limiting support part 11 for limiting the maximum downward rotation range of the connecting rod 2.

[0040] In an embodiment, the height measuring part 7 comprises a height measuring hole 71 for inserting the moving part 6 located at a specified height. Figure 3 In this embodiment, during detection, the connecting rod 2 is rotated to press the gauge 3 against the surface to be detected of the workpiece 4, and the moving part 6 is moved towards the height measuring hole 71, and the moving part 6 of the detection assembly pressed against the qualified workpiece 4 is located within the insertion range of the height measuring hole 71, while the moving part 6 of the detection assembly pressed against the unqualified workpiece 4 exceeds the insertion range of the height measuring hole 71. Thus, after the gauge 3 is pressed against the workpiece 4, the moving part 6 is moved, and the detection result can be obtained intuitively and quickly according to whether the moving part 6 can be inserted into the height measuring hole 71.

[0041] In another embodiment, the height measuring part 7 comprises a height measuring plate 72 for pressing the moving part 6 located at a specified height. Figure 1 In this embodiment, during detection, the connecting rod 2 is rotated to press the gauge 3 against the workpiece 4, and then the moving part 6 is moved towards the height measuring plate 72. If the moving part 6 can be moved below the height measuring plate 72 to be pressed by the height measuring plate 72, the detection is qualified, otherwise, the detection is unqualified. Thus, after the gauge 3 is pressed against the workpiece 4, the moving part 6 is moved, and the detection result can be obtained intuitively and quickly according to whether the moving part 6 can be moved below the height measuring plate 72.

[0042] In an embodiment, the connecting relationship between the moving part 6 and the connecting rod 2 is as follows. Figure 3 The moving part 6 is connected to the side surface of the connecting rod 2 through a spring. Thus, during detection, the connecting rod 2 is rotated downward, and if the workpiece 4 is qualified, the spring drives the moving part 6 to translate to be inserted into the height measuring hole 71 or to enter the space below the height measuring plate 72 through the elastic potential energy, and if the workpiece 4 is unqualified, the moving part 6 cannot be translated to be inserted into the height measuring hole 71 or to enter the space below the height measuring plate 72.

[0043] In another embodiment, the connecting relationship between the moving part 6 and the connecting rod 2 is as follows. Figure 1 and Figure 2The detection assembly further comprises a handle 8 detachably connected to the moving member 6, and the connecting rod 2 comprises a moving slot 21 and a handle slot 22; the moving member 6 is located in the moving slot 21, and the handle 8 is located in the handle slot 22. Thus, the handle 8 located in the handle slot 22 can only move in the handle slot 22, thereby limiting the moving range of the moving member 6 connected with the handle 8, and avoiding the moving member 6 from being excessively moved out and falling off from the connecting rod 2. Since the handle 8 is detachably connected to the moving member 6, the worker can replace the worn moving member 6, so as to avoid the influence of the accuracy of the detection result caused by the wear of the moving member 6.

[0044] In order to improve the practicability, the base 1 comprises a replacement part 13 and a connecting part 14, the connecting rod 2, the height measuring member 7 and the limiting support part 11 are arranged on the connecting part 14, the connecting part 14 is detachably connected to the replacement part 13, the replacement part 13 is detachably connected to the detection table 5, and the gauge 3 and the moving member 6 are respectively detachably connected to the connecting rod 2. Thus, by replacing the gauges 3 of different models, the replacement parts 13 of different heights or the connecting rods 2 of different lengths, the device can be used for inspecting different workpieces 4.

[0045] As a preferred embodiment, the height measuring member 7 is detachably connected to the connecting part 14. When the height measuring member 7 is worn due to excessive use, the preferred embodiment facilitates the replacement of the height measuring member 7, so as to avoid the influence of the accuracy of the detection result caused by the wear of the height measuring member 7.

[0046] The embodiments of the present application shown in the above description and the drawings are only examples and do not limit the present application. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims. The purpose of the present application has been completely and effectively achieved. The function and structural principle of the present application have been shown and explained in the embodiments, and the embodiments of the present application can be modified or replaced in any way without departing from the principle.
