Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a detection equipment. Background Art

[0002] At present, in order to control the production quality of hollow bladder skins, it is usually necessary to test the product height, inner diameters at both ends of the product, wall thickness and other data of the bladder skins.

[0003] However, in the process of dimensional inspection of hollow bladder skin, the existing inspection method is usually to use a thickness gauge to inspect the bladder skin. However, since the bladder skin to be inspected is a rubber part, the thickness gauge will produce a certain degree of compression on the bladder skin during the measurement process. The rubber part will produce a certain degree of compression deformation when it is squeezed, so the use of the thickness gauge for inspection will cause inaccurate measurement results, and the thickness gauge cannot automatically inspect the side walls of the bladder skin at all locations around the circumference, resulting in a large measurement error.

[0055] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0056] like Figures 1 to 7 As shown, an embodiment of the utility model provides a detection device, which includes a first thickness detection component 10 and a positioning fixture 20. The first thickness detection component 10 includes a first detection member 11 and a second detection member 12 that are arranged oppositely and at intervals, and the detection portion of the first detection member 11 and the detection portion of the second detection member 12 are both arranged toward the gap between the first detection member 11 and the second detection member 12. The first detection member 11 and the second detection member 12 are respectively arranged on both sides of the positioning fixture 20, and the positioning fixture 20 is provided with a positioning portion 21 for positioning the material 140, and the detection portion of the first detection member 11 and the detection portion of the second detection member 12 are both protruding from the positioning portion 21. Among them, the positioning fixture 20 is rotatably arranged so that at least a portion of the positioning portion 21 is located between the first detection member 11 and the second detection member 12.

[0057] By using the detection device provided in this embodiment, the wall thickness of the material 140 to be detected can be detected by the first detection member 11 and the second detection member 12 which are arranged relatively and spaced apart. At the same time, in this embodiment, the material 140 to be detected is positioned on the rotatable positioning fixture 20, and the positioning portion 21 of the positioning fixture 20 for positioning the material 140 is located between the first detection member 11 and the second detection member 12. By such a setting, the wall thickness of each part of the outer edge of the material 140 to be detected can be detected by rotating the positioning fixture 20, thereby obtaining multiple groups of detection data, and the average value, maximum value, minimum value, extreme value, etc. of each detection data can also be obtained, thereby obtaining a more accurate wall thickness detection result. Therefore, the detection device provided in this embodiment can solve the technical problem of large error in measuring the size of the bladder skin in the prior art.

[0058] Specifically, the first detection member 11 and the second detection member 12 are both laser sensors, and the laser lines emitted by the two laser sensors are coaxially arranged. The material can be an annular capsule.

[0059] Specifically, the positioning portion 21 is an annular positioning groove, and the inner wall surface of the positioning groove is gap-matched with one end of the material 140 close to the positioning tool 20 to prevent the material 140 from being squeezed and deformed when the positioning portion 21 positions the material 140.

[0060] Specifically, the positioning tool 20 is provided with an avoidance channel 22, and the positioning portion 21 is arranged around the avoidance channel 22. At least a portion of the first detection member 11 is arranged in the avoidance channel 22, and the positioning tool 20 is rotatably arranged around at least a portion of the first detection member 11.

With such a structural arrangement, it is possible to conveniently arrange the first detection member 11 at a suitable position in the avoidance channel 22 through the arrangement of the avoidance channel 22, so as to avoid interference between the positioning tool 20 and the first detection member 11 when the positioning tool 20 rotates. At the same time, the detection portion of the first detection member 11 is arranged to extend out of the avoidance channel 22 in order to better detect the wall thickness data of the material to be detected 140 at one end close to the positioning tool 20.

[0061] Specifically, the avoidance channel 22 is provided on the positioning fixture 20 along the extension direction of the rotation axis of the positioning fixture 20. In this way, it is more convenient to arrange the first detection member 11 at a suitable position in the avoidance channel 22 according to different sizes of the material 140 to be detected.

[0062] In this embodiment, the detection device also includes a first mounting member 30, which includes a first mounting portion 31 and a second mounting portion 32 that are spaced apart and arranged opposite to each other, and the first mounting portion 31 and the second mounting portion 32 are respectively arranged on both sides of the positioning tool 20, and the first mounting portion 31 is inserted into the avoidance channel 22, and the first detection member 11 is installed on the first mounting portion 31, and the second detection member 12 is installed on the second mounting portion 32. Among them, the first mounting member 30 can be movably arranged. With such a structural arrangement, the structural layout of the first detection member 11 and the second detection member 12 can be optimized by the arrangement of the first mounting member 30, which is convenient for improving the detection efficiency and simplifying the detection steps.

[0063] Specifically, the first mounting member 30 is a U-shaped plate, and the first mounting portion 31 and the second mounting portion 32 are parts disposed opposite to each other on the U-shaped plate.

[0064] Specifically, the detection device further includes a first driving structure 40, the driving end of which is movably arranged, and the driving end of the first driving structure 40 is drivingly connected to the first mounting member 30. With such a structural arrangement, the first mounting member 30 can be driven to move by the first driving structure 40, thereby driving the first detection member 11 and the second detection member 12 to reach a suitable detection position, thereby effectively realizing the automation of the detection operation and improving the detection efficiency.

[0065] Specifically, the driving end of the first driving structure 40 is movably arranged in the left-right direction, so as to facilitate the corresponding position adjustment according to the materials 140 of different diameters, so that the first detection member 11 and the second detection member 12 can reach the appropriate detection position.

[0066] In this embodiment, the detection device further includes a second thickness detection component 50, which is spaced apart from the first thickness detection component 10, and includes a third detection member 51 and a fourth detection member 52 which are arranged oppositely and spaced apart, and the detection portion of the third detection member 51 and the detection portion of the fourth detection member 52 are both arranged toward the gap between the third detection member 51 and the fourth detection member 52. The second thickness detection component 50 is movably arranged in a direction close to or away from the first thickness detection component 10, and the second thickness detection component 50 has a detection position and an avoidance position for avoiding the material 140. When the second thickness detection component 50 is in the detection position, the detection portion of the third detection member 51 and the detection portion of the fourth detection member 52 are respectively located on both sides of the material 140. With such a structural arrangement, the wall thickness of the material 140 to be inspected at one end away from the positioning fixture 20 can be inspected by the third inspection member 51 and the fourth inspection member 52 which are arranged relatively and at intervals. In addition, since the material 140 to be inspected is positioned on the rotatable positioning fixture 20 in this embodiment, the positions of the third inspection member 51 and the fourth inspection member 52 are adjusted so that the end of the material 140 to be inspected away from the positioning fixture 20 is located between the third inspection member 51 and the fourth inspection member 52. The positioning fixture 20 can be rotated to detect the wall thickness of each part of the outer edge of the end of the material 140 to be inspected away from the positioning fixture 20, thereby obtaining multiple groups of inspection data, and obtaining more accurate wall thickness inspection results after averaging, effectively reducing the inspection error, and also obtaining the maximum value, minimum value, extreme value, etc. of each inspection data. At the same time, the setting of the avoidance position can also better facilitate the replacement of different materials 140 to be inspected.

With such a structural setting, it is convenient to detect the height of the material 140 through the height detection component 60, which is helpful to obtain more accurate height dimension data compared with conventional manual measurement and measurement detection.

[0069] Specifically, the height detection component 60 is an edge detection sensor. Specifically, one of the fifth detection member 61 and the sixth detection member 62 is a transmitting end of the edge detection sensor, and the other of the fifth detection member 61 and the sixth detection member 62 is a receiving end of the edge detection sensor. With such a structural setting, it is convenient to detect the height of the material 140 through the height detection component 60, which is helpful to obtain more accurate height dimension data compared with conventional manual measurement and measurement detection.

[0070] Specifically, the detection device also includes a second mounting member 70, which is movably arranged in a direction close to or away from the first thickness detection component 10, and includes a third mounting portion 71 and a fourth mounting portion 72 that are relatively and spaced apart, and the third detection member 51 and the fifth detection member 61 are both mounted on the third mounting portion 71, and the fourth detection member 52 and the sixth detection member 62 are mounted on the fourth mounting portion 72.

[0075] In this embodiment, the detection device also includes a second drive structure 100, and the positioning fixture 20 is detachably connected to the transmission part of the second drive structure 100. When the positioning fixture 20 is connected to the transmission part of the second drive structure 100, the transmission part of the second drive structure 100 drives the positioning fixture 20 to move.

[0080] Specifically, the detection device in this embodiment is used to detect the end wall thickness, end inner diameter and height of the air spring bag skin.

[0081] Specifically, the wall thickness detection principle of the detection equipment in this embodiment is: two laser ranging sensors (equivalent to the first detection component 11 and the second detection component 12, or equivalent to the third detection component 51 and the fourth detection component 52) ​​are respectively arranged on both sides of the single-layer wall thickness of the product (equivalent to the material 140), and the distance between the two sensors is known to be A. The outer sensor (equivalent to the second detection component 12, or the fourth detection component 52) ​​detects the distance B between it and the outer wall of the product in real time, and the inner sensor (equivalent to the first detection component 11, or the third detection component 51) detects the distance C between it and the inner wall of the product in real time. The wall thickness of the product = ABC.

[0082] Specifically, the inner diameter detection principle of the detection equipment in this embodiment is as follows: a laser ranging sensor (equivalent to the first detection member 11, or the third detection member 51) is arranged on the inner side of the single-layer wall thickness of the product.

The inner sensor detects the distance C between it and the inner wall of the product in real time. The radius of the product here is R=E+C (the product is tightly fixed on the positioning fixture 20, and the deviation between the product axis and the rotation axis of the positioning fixture 20 can be ignored). The inner circumference of the product is C 周 =∫nΠR / 180Rdn (integrate n from 0 to 360 degrees), inner diameter D = C 周 / П.

[0083] Specifically, the height detection principle of the detection device in this embodiment is: a group of edge detection sensors (equivalent to the fifth detection member 61 and the sixth detection member 62) are respectively set on both sides of the single-layer wall thickness of the product, one side is the transmitting end, and the other side is the receiving end. The emitted signal is a laser band with a certain width, and the zero point is the center of the laser band. It is known that the distance between the center of the laser band of the two sensors and the bottom of the product is A, and the sensor detects the distance B between the upper end surface of the product and the center of the laser band in real time, and the product height H=AB.

For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0090] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0091] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
