Description

Technical Field

[0001] The present disclosure relates to the technical field of part size and shape detection, and in particular to detection equipment. Background Art

[0002] In the related art, when performing size and shape detection on the part to be measured, for example, when detecting the size, roundness and position of the sensor, the inspector will first place the part to be measured on the support seat of the three-coordinate measuring machine, so that the central part of the part to be measured is positioned by the positioning column on the support seat, and then use the probe of the three-coordinate measuring machine to move and measure multiple times to obtain multiple coordinate values ​​of multiple points of the part to be measured. After the multiple coordinate values ​​are processed by the processor, the position, aperture and roundness and other parameters of the part to be measured are determined. However, the above-mentioned three-coordinate measuring machine has a complex structure, high cost and complicated operation, which affects the detection efficiency of the part to be measured.

[0038] In order to clearly describe the present disclosure, components not related to the description are omitted, and the same or similar components throughout the specification are denoted by the same reference numerals.

[0039] Throughout this specification, when a device is said to be "connected" to another device, this includes not only "direct connection" but also "indirect connection" with other elements interposed therebetween. Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0040] Although the terms first, second, etc. are used in this document to represent various elements in some examples, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, the first interface and the second interface, etc. are represented. Furthermore, as used in this document, the singular forms "one," "an," and "the" are intended to also include the plural forms, unless there is a contrary indication in the context.

[0041] The technical terms used herein are intended only to refer to specific embodiments and are not intended to limit the present disclosure. The singular form used herein also includes the plural form unless the statement explicitly indicates otherwise. The term "comprising" as used in this specification is intended to specify specific features, regions, integers, steps, operations, elements, and / or components and does not exclude the presence or addition of other features, regions, integers, steps, operations, elements, and / or components.

Terms defined in commonly used dictionaries are additionally interpreted as having meanings consistent with relevant technical literature and the current message. Unless otherwise defined, they should not be overly interpreted as ideal or highly formalized meanings.

[0043] In the related art, when performing size and shape detection on the part to be measured, for example, when detecting the size, roundness and position of the sensor, the inspector will first place the part to be measured on the support seat of the three-coordinate measuring machine, so that the central part of the part to be measured is positioned by the positioning column on the support seat, and then use the probe of the three-coordinate measuring machine to move and measure multiple times to obtain multiple coordinate values ​​of multiple points of the part to be measured. After the multiple coordinate values ​​are processed by the processor, the position, aperture and roundness and other parameters of the part to be measured are determined. However, the above-mentioned three-coordinate measuring machine has a complex structure, high cost and complicated operation, which affects the detection efficiency of the part to be measured. Moreover, the above-mentioned positioning method has a general effect on the positioning of the area around the part to be measured. During the detection process, if the probe touches the part to be measured and its surrounding area, the part to be measured and its surrounding area are prone to movement, which affects the detection of the part to be measured.

[0044] The present disclosure provides a detection device that can detect multiple parameters such as the position and roundness of a part to be detected, and has a simple structure, low cost, and easy operation.

[0045] The part to be tested detected by the detection device of the embodiment of the present disclosure includes a main body and a mounting portion. The outer peripheral wall of the mounting portion is provided with an annular portion to be tested. The main body is provided with a first positioning hole eccentrically arranged relative to the center of the mounting portion and a hole to be tested located on the outer peripheral side of the first positioning hole. For example, Figure 1 and Figure 2 Schematic diagram of the structure of the embodiment of the present disclosure when the part to be measured is a sensor at different viewing angles. Figure 1 and Figure 2 When the part to be measured 900 is a sensor, the mounting portion 91 may be one end of the sensor, and the first positioning hole 901 may be a countersunk hole located at the other end of the sensor. The center of the first positioning hole 901 is offset from the center of the one end of the sensor, with the two being eccentrically disposed. A measuring hole 902 is provided in the middle of the sensor, located outside the first positioning hole 901. The annular portion to be measured 911 may be an annular sealing groove extending circumferentially around the mounting portion 91.

[0046] Figure 3 It is a structural diagram of the detection device of an embodiment of the present disclosure. Figure 4 Schematic diagram of a top view of a part of the structure of the detection device of the embodiment of the present disclosure. Figure 3 and Figure 4 The detection device includes a device body 11, a first positioning member 12 and a roundness detection member 13.

[0047] Among them, the device body 11 is provided with a rotation positioning hole 101 that rotates with the mounting part 91, the device body 11 is provided with a through hole 102 that is connected to the rotation positioning hole 101 and aligned with the annular test part 911, and the device body 11 is also provided with a detection hole 103 located on the outer peripheral side of the rotation positioning hole 101.

[0048] Optionally, the rotation positioning hole 101 is located on the vertical surface of the device body 11. Therefore, when the part to be tested 900 is mounted in the rotation positioning hole 101, the part to be tested 900 is directly mounted on the vertical surface, making it convenient to arrange other components from the side (e.g., the front or rear side) of the vertical surface, and convenient for the tester to perform relevant testing operations from the side (e.g., the front side) of the vertical surface while standing.

[0049] The axis of the first positioning member 12 is eccentrically arranged relative to the axis of the rotating positioning hole 101, and is arranged on the device body 11 so as to be movable axially toward / away from the first positioning hole 901, and has a first positioning portion 121 that cooperates with the first positioning hole 901 when moving closer.

[0050] Therefore, after the mounting portion 91 of the part to be tested 900 is mounted in the rotation positioning hole 101 , the part to be tested 900 may be rotated to align the first positioning hole 901 of the part to be tested 900 with the first positioning portion 121 .

[0051] At this point, the first positioning member 12 is moved closer to the rotational positioning hole 101. If the first positioning hole 901 and the first positioning portion 121 are not aligned, the first positioning portion 121 cannot be smoothly inserted into the first positioning hole 901. The part to be tested 900 is then rotated further until the first positioning portion 121 is successfully inserted into the first positioning hole 901. Because the center of the first positioning portion 121 is eccentric relative to the center of the rotational positioning hole 101, the part to be tested 900 is stopped and cannot continue to rotate about the axis of the rotational positioning hole 101.

[0052] Furthermore, the circumferential position of the detection hole 103 in the circumferential direction of the first positioning portion 121 is consistent with the circumferential position of the hole to be tested 902 in the circumferential direction of the first positioning hole 901, which has passed the position accuracy. In other words, after the first positioning hole 901 of the qualified part is positioned by the first positioning portion 121, the circumferential position of the hole to be tested 902 in the qualified part with passed position accuracy is consistent with the circumferential position of the detection hole 103, and the hole to be tested 902 and the detection hole 103 of the qualified part will overlap and be in electrical communication with each other. Therefore, if the circumferential position of the hole to be tested 902 of the part to be tested 900 is qualified, the circumferential position of the hole to be tested 902 of the part to be tested 900 positioned by the first positioning portion 121 will also overlap with the circumferential position of the detection hole 103, and the hole to be tested 902 and the detection hole 103 will be in electrical communication with each other. Conversely, if the circumferential position accuracy of the hole to be tested 902 of the part to be tested 900 is unqualified, the circumferential position of the hole to be tested 902 of the part to be tested 900 positioned by the first positioning portion 121 will be offset from the circumferential position of the detection hole 103, and there will be no electrical continuity between the hole to be tested 902 and the detection hole 103. Therefore, whether the hole to be tested 902 of the part to be tested 900 positioned by the first positioning member 12 is electrically connected to the detection hole 103 can reflect whether the circumferential position accuracy of the hole to be tested 902 is qualified.

[0053] The device body 11 is provided with a first guide portion 104 that extends linearly in a direction close to or away from the first positioning hole 901 and slidably cooperates with the first positioning member 12. Thus, when the first positioning member 12 moves along the extending direction of the first guide portion 104, the first positioning member 12 is unlikely to deviate.

[0054] Optionally, there are multiple detection holes 103, and the circumferential positional accuracy of the multiple detection holes 103 along the circumference of the first positioning portion 121 corresponds one-to-one with the circumferential positional accuracy of the multiple test holes 902 with qualified positional accuracy along the circumference of the first positioning hole 901. Thus, by observing whether the multiple test holes 902 are electrically connected to the multiple detection holes 103 in a one-to-one correspondence, it can be determined whether the circumferential positional accuracy of the multiple test holes 902 meets the requirements.

[0055] The roundness detector 13 includes a detection body 131 and a probe 132. The detection body 131 is detachably mounted on the device body 11. The probe 132 is relatively movably connected to the detection body 131 and is configured to extend through the through-hole 102 into the rotation positioning hole 101. When the probe 132 is extended, the movement stroke formed by the pressure of the annular portion to be measured 911 with qualified roundness is within a predetermined range. Whether the movement stroke formed by the pressure of the annular portion to be measured 911 when the probe 132 is extended is within the predetermined range reflects whether the roundness of the annular portion to be measured 911 is qualified.

[0056] That is, after the part to be measured 900 is rotatably mounted in the rotation positioning hole 101, the annular portion to be measured 911 is also disposed in the rotation positioning hole 101 and aligned with the through-hole 102. At this time, when the detection body 131 of the roundness detection member 13 is mounted on the device body 11, the probe 132 of the roundness detection member 13 passes through the through-hole 102 and extends into the rotation positioning hole 101. During the installation process, when the probe 132 contacts the annular portion to be measured 911, the annular portion to be measured 911 presses the probe 132, causing the probe 132 to move relative to the detection body 131.

[0057] For the annular portion to be measured 911 with qualified roundness on a qualified part, the degree of depression or protrusion of the portion where the annular portion to be measured 911 is aligned with the perforation 102 relative to the standard circle is limited and within the predetermined error range. Therefore, the movement stroke of the stylus 132 formed by the pressure of the annular portion to be measured 911 with qualified roundness will be within the predetermined range. Therefore, if the roundness of the annular portion to be measured 911 of the part to be measured 900 is qualified, when the stylus 132 is inserted into the rotation positioning hole 101, the movement stroke of the stylus 132 formed by the pressure of the annular portion to be measured 911 should also be within the predetermined range. Conversely, if the roundness of the annular portion to be measured 911 of the part to be measured 900 is unqualified, after the detection body 131 is installed in the equipment body 11, the movement stroke of the stylus 132 formed by the pressure of the annular portion to be measured 911 will exceed the predetermined range. Therefore, after the detection body 131 is installed in the equipment body 11 , whether the moving stroke of the probe 132 pressed by the annular portion to be measured 911 is within a predetermined range can reflect whether the roundness of the annular portion to be measured 911 is qualified.

[0058] Optionally, the inspection body 131 includes a display member and a conversion member. The conversion member is connected to the stylus 132 and the display member so that the travel range of the stylus 132 can be displayed through the display member, allowing the inspector to intuitively determine the travel range of the stylus 132. For example, the roundness inspection member 13 can be a testing device such as a dial indicator or micrometer. When not installed in the device body 11, the pointer of the dial indicator or micrometer can be calibrated to zero. Therefore, after the dial indicator or micrometer is installed in the device body 11, the scale value indicated by the pointer on the dial indicator or micrometer reflects the travel range of the stylus 132. When the roundness inspection member 13 is a dial indicator or micrometer, the display member includes a dial with scale and a pointer that rotates on the dial to indicate the scale. The conversion member includes a rack and a gear. The rack is connected to the stylus 132 to move with the stylus 132. The gear is connected to the pointer and meshes with the rack, so that the rack moves and drives the pointer to rotate through a predetermined scale range on the dial. Thus, the scale change indicated by the pointer on the dial can reflect the travel of the probe 132, making it easier for the inspector to intuitively determine whether the travel of the probe 132 is within the predetermined range.

[0059] Optionally, the device body 11 is provided with a resting portion 111 located above the through-hole 102. The roundness detector 13 rests on the resting portion 111, and a probe 132 of the roundness detector 13 extends through the resting portion 111 and into the through-hole 102. Thus, when the roundness detector 13 rests downward on the resting portion 111 or is lifted off the resting portion 111, the roundness detector 13 is installed and removed from the device body 11, making installation and removal of the roundness detector 13 convenient.

[0060] In the above process, the detection device disclosed in the present invention can detect the position and roundness of the part 900 to be detected, and has a simple structure, low cost and easy operation.

[0061] Optionally, see Figure 3 and Figure 4, the detection equipment also includes a detection shaft 14. The outer diameter of the detection head of the detection shaft 14 is configured to allow it to be plugged into the hole to be measured 902 with a qualified aperture. In other words, when the hole to be measured 902 with a qualified aperture on the qualified part is inserted by the detection head, the detection head can be smoothly plugged into the hole to be measured 902 with a qualified aperture on the qualified part. Therefore, when the aperture of the hole to be measured 902 of the part to be measured 900 is detected, if the detection head can be inserted into the hole to be measured 902 of the part to be measured 900, it means that the aperture of the hole to be measured 902 of the part to be measured 900 is qualified. On the contrary, if the detection head cannot be inserted into the hole to be measured 902 of the part to be measured 900, it means that the inner diameter of the hole to be measured 902 of the part to be measured 900 is too small and the processing is unqualified.

[0062] Optionally, the outer diameter of the detection head of the detection shaft 14 is further configured to allow for plug-fitting with the detection hole 103. Thus, when testing the circumferential position of the hole 902 to be tested, the detection head can be directly passed through the hole 902 to be tested of the part 900 to be tested and inserted into the detection hole 103. If the detection head is successfully inserted, it indicates that the detection hole 103 and the hole 902 to be tested of the part 900 to be tested are in electrical communication, and the circumferential position of the hole 902 to be tested is qualified. Conversely, if the detection head cannot be successfully inserted, it indicates that the detection hole 103 and the hole 902 to be tested of the part 900 to be tested are not in electrical communication, and the circumferential position of the hole 902 to be tested is unqualified. Therefore, the inspector can directly insert the inspection shaft 14 while standing. According to the insertion status of the inspection shaft 14, that is, whether it is inserted into the hole to be measured 902 and whether it passes through the hole to be measured 902 and is inserted into the inspection hole 103, it can be judged whether the aperture of the hole to be measured 902 and the circumferential position of the hole to be measured 902 are qualified. One insertion action can detect multiple parameters of the hole to be measured 902, and the inspection efficiency is high.

[0063] It is worth mentioning that during the inspection process of the above-mentioned inspection shaft 14, if only the central part of the part to be tested 900 is positioned, then when the inspection shaft 14 is inserted into the hole to be tested 902 for inspection, the area around the hole to be tested 902 is prone to movement, affecting the insertion inspection process of the inspection shaft 14. Therefore, the inspection device also includes at least one clamping assembly 15. The clamping assembly 15 is arranged on the device body 11, and each clamping assembly 15 includes a clamping member 151 and an elastic member 152. The clamping member 151 can move toward / away from the device body 11 along a preset direction, and is provided with an exposure opening 15101, so that when it moves to the clamping position, the exposure opening 15101 exposes the hole to be tested 902 and presses the part to be tested 900 on the device body 11, and when it moves to the release position, the part to be tested 900 is released. The elastic member 152 forms an elastic force acting on the clamping member 151 to maintain the clamping position.

[0064] Thus, when the pressing member 151 is in the pressing position, under the action of the elastic force provided by the elastic member 152, the pressing member 151 can press the outer portion of the hole to be tested 902 against the device body 11, and make the hole to be tested 902 located within the exposure opening 15101 and exposed through the exposure opening 15101. Since the area around the hole to be tested 902 is suppressed by the pressing member 151, when the detection shaft 14 detects the hole to be tested 902, the area around the hole to be tested 902 is unlikely to move, resulting in high stability, which is conducive to improving the stability of the hole to be tested 902 during detection. After the detection of the part to be tested 900 is completed, the pressing member 151 can move to the release position to release the part to be tested 900, thereby facilitating the unloading of the part to be tested 900.

[0065] Optionally, each of the pressing assemblies 15 includes a force transmission member 153. The force transmission member 153 is movable along a predetermined direction and extends out of the device body 11, and the extending portion is interlockingly connected to the pressing member 151. Both ends of the elastic member 152 are disposed against the side surface of the force transmission member 153 and the device body 11 facing away from the pressing member 151.

[0066] Thus, the force transmission member 153 can move in conjunction with the movement of the clamping member 151, for example, it can move synchronously with the clamping member 151 as the clamping member 151 moves, and the elastic force of the elastic member 152 acting on the force transmission member 153 can act on the clamping member 151, thereby driving the clamping member 151 to reset and maintain it in the clamping position.

[0067] Optionally, the force transmission member 153 is movably and rotatably provided on the device body 11 , and in the released position, the pressing member 151 is attached to the device body 11 and is located outside the installation coverage area of ​​the part to be tested 900 on the device body 11 .

[0068] Therefore, when the part to be tested 900 is not installed on the device main body 11, the pressing member 151 is located in the released position, the pressing member 151 is attached to the device main body 11, and is located outside the installation coverage area of ​​the part to be tested 900 on the device main body 11. Therefore, the pressing member 151 avoids the installation coverage area of ​​the part to be tested 900 on the device main body 11, making it convenient for the part to be tested 900 to be installed on the device main body 11. After the part to be tested 900 is installed on the device body 11, the pressing member 151 is moved away from the device body 11, and the pressing member 151 is rotated so that the pressing member 151 extends into the installation covering area, and the exposed opening 15101 on the pressing member 151 is aligned with the hole to be tested 902. At this time, the pressing member 151 is released, and under the elastic force of the elastic member 152, the pressing member 151 presses the part to be tested 900 so that the exposed opening 15101 exposes the hole to be tested 902.

[0069] When the inspection of the part to be tested 900 is completed, the pressing member 151 is moved away from the part to be tested 900, and the pressing member 151 is rotated again in the direction opposite to the previous rotation direction, so that the pressing member 151 avoids the installation coverage area of ​​the part to be tested 900 on the equipment main body 11. At this time, the pressing member 151 is released, and under the elastic force of the elastic member 152, the pressing member 151 is again tightly attached to the equipment main body 11, thereby facilitating the loading and inspection of the next part to be tested 900.

[0070] Optionally, there are multiple pressing assemblies 15 , and the multiple pressing assemblies 15 are arranged at intervals along the circumference of the main positioning hole to press the multiple surrounding parts of the multiple holes to be measured 902 in a one-to-one correspondence.

[0071] Optionally, see Figure 1 、 Figure 3 and Figure 4, the mounting portion 91 is provided with a second positioning hole 9101. The detection device further includes a second positioning member 16. The second positioning member 16 is movably provided on the device body 11 in the direction of being far from / close to the second positioning hole 9101, and is arranged on opposite sides of the rotating positioning hole 101 with the first positioning member 12, and has a second positioning portion 161 for cooperating with the second positioning hole 9101 when moving closer. Thus, after the first positioning portion 121 positions the part to be tested 900, the second positioning member 16 is driven to move close to the second positioning hole 9101, so that the second positioning portion 161 is cooperated with and set in the second positioning hole 9101, thereby limiting and positioning the part to be tested 900 from the other side of the part to be tested 900, and having a good positioning effect on the part to be tested 900.

[0072] Optionally, the second positioning member 16 is movably disposed on the device body 11 in a direction away from or closer to the second positioning hole 9101. Thus, after the first positioning portion 121 positions the part to be tested 900, the second positioning member 16 is driven to move closer to the second positioning hole 9101, and the second positioning portion 161 can be inserted into the second positioning hole 9101, thereby achieving mutual engagement with the second positioning hole 9101.

[0073] Optionally, the device body 11 is provided with a second guide portion 105, i.e., a second slide hole, which extends in a direction away from / close to the second positioning hole 9101 and slides with the second positioning member 16. This helps ensure that the second positioning member 16 moves stably during movement and is unlikely to deviate.

[0074] Figure 5 Schematic diagram of the structure of multiple calipers in the embodiment of the present disclosure. Figure 1 and Figure 5 The testing device further includes a first caliper 17. The first caliper 17 has a first bayonet 1701. The inner diameter of the first through end 171 of the first bayonet 1701 is configured to allow the annular portion to be tested 911 with a qualified outer diameter to pass through, and the inner diameter of the first stop end 172 is configured to block the annular portion to be tested 911 with a qualified outer diameter from passing through. Whether the annular portion to be tested 911 can pass through the first through end 171 and be blocked by the first stop end 172 reflects whether the outer diameter of the annular portion to be tested 911 is qualified.

[0075] In other words, the first caliper 17 is designed to be inserted through the first bayonet 1701 and onto the outside of the annular portion to be measured 911, and the inner diameter of the first through end 171 of the first bayonet 1701 is greater than the inner diameter of the first stop end 172. When the annular portion to be measured 911 passes through the first through end 171 when inserted into the first bayonet 1701, it can be blocked by the first stop end 172 and prevented from passing through. Thus, when the first caliper 17 is used to measure the outer diameter of the annular portion to be measured 911, if the annular portion to be measured 911 passes through the first through end 171 and is blocked by the first stop end 172, it can be determined that the outer diameter of the annular portion to be measured 911 is between the inner diameter values ​​of the first through end 171 and the inner diameter values ​​of the first stop end 172, and the outer diameter of the annular portion to be measured 911 passes. Otherwise, the outer diameter of the annular portion to be measured 911 fails to pass.

[0076] Optionally, see Figure 1 and Figure 5 The mounting portion 91 is provided with a first portion to be measured 912 and a second portion to be measured 913 located on opposite sides of the annular portion to be measured 911. The second caliper 18 is provided with a second bayonet 1801. The inner diameter of the second through end 181 of the second bayonet 1801 is configured to allow the first portion to be measured 912 with a qualified outer diameter to pass through, and the inner diameter of the second stop end 182 is configured to prevent the first portion to be measured 912 with a qualified outer diameter from passing through. Whether the first portion to be measured 912 can pass through the second through end 181 and be prevented by the second stop end 182 reflects whether the outer diameter of the first portion to be measured 912 is qualified.

[0077] Thus, the second caliper 18 is designed to be inserted through the second bayonet 1801 and onto the exterior of the first portion to be measured 912, and the inner diameter of the second through end 181 of the second bayonet 1801 is greater than the inner diameter of the second stop end 182. If the first portion to be measured 912 has a qualified outer diameter, it can pass through the second through end 181 when inserted into the second bayonet 1801, and can be blocked from passing through by the second stop end 182. Thus, when the second caliper 18 is used to measure the outer diameter of the first portion to be measured 912, if the first portion to be measured 912 can pass through the second through end 181 and is blocked by the second stop end 182, it can be determined that the outer diameter of the first portion to be measured 912 is between the inner diameter values ​​of the second through end 181 and the inner diameter values ​​of the second stop end 182, and the outer diameter of the second portion to be measured 913 is qualified. Conversely, the outer diameter of the second portion to be measured 913 is unqualified.

[0078] The third caliper 19 is provided with a third bayonet 1901. The inner diameter of the third through end 191 of the third bayonet 1901 is configured to allow the second part to be measured 913 with a qualified outer diameter to pass through, and the inner diameter of the third stop end 192 is configured to hinder the second part to be measured 913 with a qualified outer diameter from passing through, so as to reflect whether the outer diameter of the second part to be measured 913 is qualified by whether the second part to be measured 913 can pass through the third through end 191 and be hindered by the third stop end 192.

[0079] Thus, the third caliper 19 is capable of being inserted through the third bayonet 1901 and positioned outside the second portion to be measured 913. The inner diameter of the third through end 191 of the third bayonet 1901 is greater than the inner diameter of the third stop end 192. A second portion to be measured 913 with a qualified outer diameter can pass through the second through end 181 when inserted into the third bayonet 1901, but can be blocked by the third stop end 192 and prevented from passing through. Thus, when the third caliper 19 is used to measure the outer diameter of the second portion to be measured 913, if the second portion to be measured 913 can pass through the third through end 191 and is blocked by the third stop end 192, it can be determined that the outer diameter of the second portion to be measured 913 is between the inner diameter values ​​of the third through end 191 and the inner diameter values ​​of the third stop end 192, indicating that the outer diameter of the second portion to be measured 913 is qualified. Otherwise, the outer diameter of the second portion to be measured 913 is unqualified.

[0080] Optionally, see Figure 3 and Figure 4 The detection device also includes a placement seat 21. The placement seat 21 has a first slot 2101 with an open top for inserting the first caliper 17, a second slot 2102 with an open top for inserting the second caliper 18, and a third slot 2103 with an open top for inserting the third caliper 19. As a result, the first caliper 17, the second caliper 18, and the third caliper 19 can be stored and removed by simply plugging in and out, making storage and removal convenient.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this disclosure.
