[0037] At present, the detection of handle dimensions in the market mostly adopts traditional manual measurement or simple mechanical measuring equipment. However, since most existing handles are irregular in shape, there are many positions and dimensions that need to be detected. Therefore, when using traditional manual measurement methods for measurement, there are disadvantages such as low measurement accuracy, complex measurement operation, and low efficiency, which is difficult to meet the needs of modern industrial production for high precision and high efficiency.
[0038] Based on the above problems, the embodiment of the present disclosure provides a dimension detection device. After the part positioning mechanism positions the part to be measured in the part placement area, the extension length of the second detection part in the direction of the dimension to be measured is the error range of the dimension to be measured. Therefore, it is only necessary to push the detection part in the direction close to the part to be measured, and it is possible to determine whether the dimension of the part to be measured is within the qualified range according to whether the edge of the part to be measured contacts the first detection part and the second detection part. The operation is simple and the multiple dimensions of the part to be measured can be detected quickly, thereby improving the efficiency of dimension detection.
[0039] Figure 1 Shown in the figure is a schematic diagram of the structure of the part to be tested in an embodiment of the present disclosure. Figure 2 Shown in the figure is a schematic diagram of the overall structure of the size detection device in an embodiment of the present disclosure. Figure 3 The figure shows the overall structure diagram of the dimension detection device and the part to be detected in the embodiment of the present disclosure. Figure 4 The figure shows the overall structure of the detection element in the embodiment of the present disclosure. Figure 1 and Figure 4 In the example, the size detection device includes a mounting base 20 , a part positioning mechanism 30 and at least one detection member 40 .
[0040] Exemplarily, the part positioning mechanism 30 is provided on the mounting base 20, for positioning the part 10 to be measured in a part placement area 201 on the mounting base 20. Each of the detection members 40 has a detection portion 41, which can move closer to or farther from the placement area so that the detection portion 41 enters or leaves the part placement area 201 to contact or move away from the part 10 to be measured. The detection portion 41 includes: a first detection portion 411, which determines the position of the maximum qualified size of the part 10 to be measured in the direction of the measured size at a first proximal end 412 close to the part 10 to be measured; and a second detection portion 413, which is arranged adjacent to the first proximal end 412 and extends parallel to the direction of the measured size, and forms a drop further away from the part placement area 201 than the first detection portion 411, and the second detection portion 413 determines the position of the minimum qualified size of the part 10 to be measured in the direction of the measured size close to the second proximal end 414 of the part 10 to be measured. The fact that the first detection portion 411 does not contact the part 10 to be tested and the second detection portion 413 contacts the part 10 to be tested corresponds to a qualified result of the part 10 to be tested in the corresponding dimension direction to be tested.
[0041] Exemplarily, the extension length of the second detection portion 413 in the direction of the dimension to be measured is the error range of the dimension to be measured. Exemplarily, the detection member 40 is implemented in multiple pieces; multiple detection members 40 are arranged on the mounting base 20 corresponding to the positions of multiple parts to be measured of the part 10 to be measured. It can be understood by those skilled in the art that when the part 10 to be measured is a handle, multiple detection members 40 respectively measure the length, width, height or other specified dimensions of the part 10 to be measured, so the position of each detection member 40 and the direction close to or away from the part placement area 201 are adjusted according to actual needs.
[0042] The benefit of the above arrangement is that after the part positioning mechanism 30 positions the part 10 to be measured in the part placement area 201, the extension length of the second detection part 413 in the direction of the dimension to be measured is the error range of the dimension to be measured. Therefore, it is only necessary to push the detection member 40 in the direction close to the part 10 to be measured, and whether the dimension of the part 10 to be measured is within the qualified range can be determined according to whether the edge of the part 10 to be measured contacts the first detection part 411 and the second detection part 413. The operation is simple and can quickly detect multiple dimensions of the part 10 to be measured, thereby improving the efficiency of dimension detection. It can be understood by those skilled in the art that the operator can perform dimension detection on the part 10 to be measured with different dimension error ranges by changing the extension length of the second detection part 413 in the direction of the dimension to be measured.
[0043] Exemplarily, the first detection portion 411 is implemented as a vertical side wall formed on the detection portion 41 of the detection member 40. In this embodiment, the first detection portion 411 is implemented as a detection surface of the vertical side wall of the detection portion 41 of the detection member 40. The advantage of such a configuration is that when the part 10 to be tested is fixed, the detection portion 41 of the detection member 40 can provide a larger installation space for the installation of the part 10 to be tested without affecting subsequent testing, thereby further improving the detection efficiency.
[0044] Figure 5 The figure shows the overall structure of the detection member in another embodiment of the present disclosure. Figure 5 In the example, the detection part of the detection member is implemented with a wedge-shaped cross section. The first detection part 411A is implemented as a detection line at the tip and vertical of the detection part 41A of the detection member 40A. The advantage of such a setting is that the space occupied by the detection member 40A can be further reduced, and the overall size and weight of the size detection device can be reduced.
[0045] Exemplarily, the detection member 40 is provided in a clearance fit through the mounting base 20. In this way, the assembly accuracy of the size detection device can be improved, while the measurement error caused by the shaking of the detection member 40 can be avoided, thereby further improving the measurement accuracy.
[0046] Exemplarily, the detection member 40 further includes an anti-detachment portion 42, and the area where the mounting base 20 and the detection member 40 are combined is located between the detection portion 41 and the anti-detachment portion 42. The advantage of the above arrangement is that it is possible to prevent the detection member 40 from detaching from the mounting base 20 when the detection member 40 is pulled back to provide an installation space for the part to be tested 10.
[0047] In another embodiment, the area on the mounting base that is slidably coupled to the detection member is implemented as an independent unit, such as a connecting plate, which is detachably connected to the mounting base, and the detection member is slidably coupled to the connecting plate. In this way, by changing the position of the connecting plate and replacing the detection member of different specifications, the parts to be tested of different specifications can be tested, thereby improving the applicability of the present disclosure.
[0048] Figure 6 The figure shows the overall structure of the dimension detection device and the part to be detected from another perspective in the embodiment of the present disclosure. Figure 6 In the example, the part positioning mechanism 30 includes a positioning member 31 and a clamping member 32; the positioning member 31 is arranged on the mounting base 20, and the top wall forms a positioning surface 311 (such as Figure 2 As shown); the clamping member 32 can be arranged on the mounting base 20 close to or far away from the positioning member 31 to clamp or disengage the part 10 to be tested between the positioning member 31 and the clamping member 32.
[0049] Exemplarily, the clamping member 32 is implemented to be arranged on the mounting base 20 so as to swing up and down along an arc line and approach or move away from the positioning member 31. Exemplarily, the clamping member 32 includes a connecting seat 321, a first force arm 322, a second force arm 323, a third force arm 324 and a clamping block 325; the connecting seat 321 is arranged on the mounting base 20; one end of the first force arm 322 is hinged to one end of the connecting seat 321 away from the part to be measured 10; one end of the second force arm 323 is hinged to one end of the connecting seat 321 close to the part to be measured 10; the clamping block 325 is arranged at the other end of the second force arm 323; one end of the third force arm 324 is hinged to the middle area of the second force arm 323, and the other end is hinged to the other end of the first force arm 322. Exemplarily, the other end of the third force arm 324 is also provided with an operating portion 3241.
[0050] Those skilled in the art can understand that when it is necessary to fix the part 10 to be tested, one end of the part 10 to be tested is placed on the positioning member 31 and is attached to the positioning surface 311, and then the operating part 3241 is operated to make the other end of the first force arm 322 swing in the direction of the first force arm 322, and at the same time, the other end of the first force arm 322 pushes the second force arm 323 to swing from top to bottom through the third force arm 324 until the clamping block 325 is pressed against the part 10 to be tested. When the part 10 to be tested is to be unfixed, the operating part 3241 is operated to make the other end of the first force arm 322 swing in the direction away from the first force arm 322, and at the same time, the other end of the first force arm 322 pulls the second force arm 323 to swing from bottom to top through the third force arm 324 until the clamping block 325 is separated from the part 10 to be tested.
[0051] In another embodiment, the clamping block is implemented to be disposed on the mounting base so as to move up and down in a vertical direction toward or away from the positioning member, so as to clamp or release the part to be tested between the positioning member and the clamping member. For example, the clamping block is driven by a vertically disposed screw to move toward or away from the positioning member.
[0052] For example, the clamping block 325 can be arranged at the other end of the second force arm 323, close to or away from the second force arm 323. The advantage of such arrangement is that the clamping member 32 can clamp the parts 10 to be tested of different thicknesses by adjusting the distance between the clamping block 325 and the other end of the second force arm 323.
[0053] Exemplarily, the wall surface of the clamping block 325 that contacts the part to be tested 10 is provided with a protective layer 3251. Further exemplary, the protective layer 3251 is implemented as a rubber block. It can be understood by those skilled in the art that the rubber block can prevent the clamping block 325 from crushing the part to be tested 10 when it is pressed against the part to be tested 10.
[0054] In another embodiment, the size detection device further includes a control unit, which includes a controller, at least one detector and at least one prompter. The detector and the prompter are respectively communicatively connected to the controller. Exemplarily, the detector is implemented as a pressure sensor. The pressure sensor matches the number of the detection members, and the pressure sensor is correspondingly arranged on the detection member, and when the second detection part does not contact the part to be tested, the pressure sensor abuts the mounting base and transmits the pressure data to the controller, and the controller generates the pressure data and causes the prompter to issue a prompt action. Exemplarily, the prompt action is implemented as at least one of a buzzer, an alarm or a vibration.
[0055] In summary, as described above, the embodiment of the present disclosure provides a dimension detection device, including: a mounting base. A part positioning mechanism is provided on the mounting base, for positioning the part to be measured in a part placement area on a mounting base. At least one detection member has a detection portion, which can move closer to or farther from the placement area so that the detection portion enters or leaves the part placement area to contact or move away from the part to be measured. The detection portion includes: a first detection portion, which is extended and arranged parallel to the direction of the dimension to be measured, and determines the position of the maximum qualified dimension of the part to be measured in the direction of the dimension to be measured at the first proximal end close to the part to be measured; and a second detection portion, which is extended and arranged adjacent to the first proximal end parallel to the direction of the dimension to be measured, and forms a drop further away from the part placement area than the first detection portion, and the second detection portion determines the position of the minimum qualified dimension of the part to be measured in the direction of the dimension to be measured near the second proximal end of the part to be measured. Wherein, the first detection portion does not contact the part to be measured and the second detection portion contacts the part to be measured, which corresponds to the qualified result of the part to be measured in the corresponding direction of the dimension to be measured. The advantage of the above arrangement is that after the part positioning mechanism positions the part to be measured in the part placement area, the extension length of the second detection part in the direction of the measured dimension is within the error range of the measured dimension. Therefore, it is only necessary to push the detection part in the direction close to the part to be measured, and it is possible to determine whether the size of the part to be measured is within the qualified range according to whether the edge of the part to be measured contacts the first detection part and the second detection part. The operation is simple and multiple dimensions of the part to be measured can be detected quickly, thereby improving the efficiency of dimension detection.
[0056] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the protection scope of the present disclosure.
