Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixture positioning technology, and in particular to a calibration device. Background Technology
[0002] When positioning a product, a turntable typically rotates a fixture to a preset position. Then, a positioning element positioned below the turntable extends outwards to push the fixture, thus detaching the fixture from the turntable and completing the positioning process. However, this positioning process is cumbersome, resulting in low positioning efficiency. Furthermore, the fixture is prone to shifting during the pushing process, leading to low positioning accuracy. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a positioning device to improve positioning efficiency and positioning accuracy.
[0004] This application provides a calibration device for calibrating multiple sets of fixtures disposed on a turntable component. The calibration device includes:
[0005] Multiple sets of adjustment components are spaced apart along the rotation direction of the turntable component. Each set of adjustment components is used to support one of the fixtures and drive the corresponding fixture to slide relative to the turntable component.
[0006] The calibration assembly includes a lifting member, a holding member, and a calibration member. The lifting member is disposed adjacent to the turntable and connected to the holding member. The lifting member is used to drive the holding member to move closer to the turntable so that the holding member presses the fixture to the corresponding adjustment assembly. The holding member is provided with a calibration hole. The calibration member is used to be inserted into the calibration hole and the receiving hole opened in the fixture to calibrate the fixture.
[0007] In use, the aforementioned calibration device first places multiple sets of fixtures onto corresponding adjusting components to stably hold the fixtures. Then, a turntable rotates the fixtures in a preset direction, aligning the holding component with the fixture to be calibrated. Next, a lifting component drives the holding component to press the fixture against the adjusting component, and the adjusting component drives the fixture to slide relative to the turntable, aligning and connecting the calibration hole with the receiving hole on the fixture. The calibration component is then inserted into the calibration hole and receiving hole to calibrate the fixture's position and orientation. Finally, the holding component and calibration component are released from the calibrated fixture, and the turntable moves the calibrated fixture away, moving another fixture to be calibrated below the holding component for repeated calibration. Thus, the calibration device, by driving the fixture to slide relative to the turntable through the adjusting component and inserting the calibration component into the calibration hole and receiving hole, achieves rapid and accurate calibration of the fixture's position and orientation, while simplifying the fixture positioning process and improving positioning efficiency and accuracy.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0037] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.
[0038] Please see Figure 1This application provides a calibration device 100, which includes an adjustment component 10 and a calibration component 20. The number of adjustment components 10 is multiple. The calibration device 100 is used to calibrate multiple sets of fixtures 300 disposed on a turntable component 200. The multiple sets of fixtures 300 correspond one-to-one with the multiple sets of adjustment components 10.
[0039] Please see Figure 1 , Figure 2 and Figure 3 Multiple sets of adjustment components 10 are spaced apart along the rotation direction of the turntable 200. Each set of adjustment components 10 corresponds to a set of fixtures 300. Each set of adjustment components 10 carries a fixture 300. The adjustment components 10 are used to drive the corresponding fixture 300 to slide relative to the turntable 200. The correction component 20 includes a lifting component 21, a holding component 22, and a correction component 23. The lifting component 21 is disposed adjacent to the turntable 200 and connected to the holding component 22. The lifting component 21 is used to drive the holding component 22 to move closer to the turntable 200, so that the holding component 22 presses the fixture 300 to the corresponding adjustment component 10. The holding component 22 is provided with a correction hole 221. The correction component 23 is used to be inserted into the correction hole 221 and the receiving hole 301 opened in the fixture 300 to correct the fixture 300.
[0040] When using the aforementioned calibration device 100, firstly, multiple sets of fixtures 300 are placed on corresponding adjustment components 10 to stably hold the fixtures 300; then, the turntable 200 drives the fixtures 300 to rotate in a preset direction so that the holding member 22 corresponds to the fixture 300 to be calibrated; next, the lifting member 21 drives the holding member 22 to press the fixture 300 against the adjustment member 12, and the adjustment component 10 drives the fixture 300 relative to the turntable 200. The fixture 300 is slidable so that the calibration hole 221 corresponds to and connects with the receiving hole 301 on the fixture 300. The calibration member 23 is inserted into the calibration hole 221 and the receiving hole 301 to calibrate the position and orientation of the fixture 300. Finally, the holding member 22 and the calibration member 23 are released from the calibrated fixture 300, and the turntable 200 moves the calibrated fixture 300 away, and moves another fixture 300 to be calibrated to the underside of the holding member 22 for repeated calibration. In this way, the calibration device 100 drives the fixture 300 to slide relative to the turntable 200 through the adjusting component 10, and the calibration member 23 is inserted into the calibration hole 221 and the receiving hole 301 to achieve rapid and accurate calibration of the position and orientation of the fixture 300, while simplifying the positioning process of the fixture 300, thereby improving positioning efficiency and positioning accuracy.
[0041] Please see Figure 1 and Figure 2In some embodiments, the adjustment assembly 10 includes a connector 11, an adjustment member 12, and a support member 13. The connector 11 is disposed on the turntable 200, and the adjustment member 12 is disposed on the side of the connector 11 opposite to the turntable 200. The support member 13 is connected to the adjustment member 12, and a support body 131 is provided on the side of the support member 13 opposite to the connector 11. The support body 131 is used to insert into the fixture 300 to fix the fixture 300 to the support member 13. The support member 13 is configured to drive the fixture 300 to move under the drive of the adjustment member 12. Exemplarily, the adjustment member 12 can be any adjustment part, adjustment block, or similar adjustment plate capable of driving the support member 13 to drive the fixture 300 to move, for example, a manual slide, to drive the fixture 300 to move in two directions on a horizontal plane.
[0042] Thus, through the above configuration, the support 131 can be inserted into the fixture 300 to fix the fixture 300 to the support 13, so that the adjusting member 12 drives the support 13 to stably move the fixture 300, thereby achieving stable adjustment of the position of the fixture 300 and ensuring that the calibrating member 23 stably calibrates the position and orientation of the fixture 300, thereby improving the calibration stability.
[0043] Please see Figure 1 and Figure 2 In some embodiments, the end of the connector 11 away from the center of the turntable 200 is provided with a positioning groove 111. The correction device 100 also includes a limiting component 30, which is provided on one side of the turntable 200. The limiting component 30 is used to be inserted into the positioning groove 111 to position the connector 11 and the turntable 200.
[0044] Thus, through the above settings, when the turntable 200 moves the fixture 300 to be calibrated to below the holding member 22, the limiting component 30 can be inserted into the positioning groove 111 to position the connecting member 11 and the turntable 200, ensuring that the holding member 22 corresponds to the positioned fixture 300, and preventing the turntable 200 from causing the fixture 300 to rotate during the calibration process, thereby ensuring that the calibrating member 23 stably calibrates the fixture 300, thereby providing positioning stability and positioning accuracy.
[0045] Please see Figure 2 and Figure 3 In some embodiments, the limiting component 30 includes a limiting drive member 31, a guide member 32, and a limiting member 33. The limiting drive member 31 is disposed on one side of the turntable member 200, and the guide member 32 is located between the limiting drive member 31 and the turntable member 200, and the guide member 32 has a guide groove 321. The limiting member 33 is movably inserted through the guide groove 321 and connected to the limiting drive member 31, and the limiting member 33 is configured to be inserted into the positioning groove 111 under the drive of the limiting drive member 31. Exemplarily, the limiting drive member 31 can be a cylinder.
[0046] Thus, through the above settings, the limiting drive 31 drives the limiting member 33 to move closer to the connecting member 11, which enables the limiting member 33 to move stably closer to the positioning groove 111 under the limitation of the guide groove 321, ensuring that the limiting member 33 is accurately inserted into the positioning groove 111, thereby improving the positioning accuracy of the limiting member 33.
[0047] Please see Figure 3 In some embodiments, the limiting component 30 further includes a fixing member 34, a first sensing member 35, and a second sensing member 36. The fixing member 34 is disposed adjacent to the limiting member 33. The first sensing member 35 and the second sensing member 36 are disposed at a distance from the fixing member 34 and are both electrically connected to the limiting drive member 31 and the turntable member 200. The second sensing member 36 is disposed on the side of the first sensing member 35 away from the turntable member 200. The first sensing member 35 is used to sense the insertion of the limiting member 33 into the positioning groove 111, and the second sensing member 36 is used to sense the removal of the limiting member 33 from the positioning groove 111. Exemplarily, the first sensing member 35 and the second sensing member 36 can be any detection part, detection rod, or similar detection head capable of detecting the position of the limiting member 33, such as a proximity sensor, position sensor, etc.
[0048] Thus, with the above configuration, when the fixture 300 rotates to below the holding member 22, the limiting member 33 is inserted into the positioning groove 111. The first sensing member 35 senses that the limiting member 33 has been inserted into the positioning groove 111 and sends an electrical signal to the turntable member 200, so that the turntable member 200 stops rotating. After the calibration member 23 completes the calibration operation of the fixture 300, the limiting member 33 moves out of the positioning groove 111. The second sensing member 36 senses that the limiting member 33 has moved out of the positioning groove 111 and sends an electrical signal to the turntable member 200, so that the turntable member 200 drives the calibrated fixture 300 to continue rotating in a preset direction, thereby ensuring that the calibration component 20 stably calibrates the fixture 300 and improving the calibration stability.
[0049] Please continue reading. Figure 3 In some embodiments, the limiting member 33 is provided with a limiting body 331, which is rotatably disposed at one end of the limiting member 33 adjacent to the turntable member 200 and is adapted to the positioning groove 111. The limiting body 331 is configured to be inserted into the positioning groove 111. For example, the limiting body 331 can be a track bearing.
[0050] Thus, through the above-mentioned arrangement, the limiting body 331 can form a rolling contact with the groove wall of the positioning groove 111 during the process of being inserted into the positioning groove 111, thereby reducing the friction between the limiting member 33 and the groove wall of the positioning groove 111, which is conducive to the smooth positioning of the connecting member 11 and the turntable member 200 by the limiting member 33.
[0051] Please see Figure 1In some embodiments, the calibration device 100 further includes a plurality of detection elements 40, each corresponding to a plurality of adjustment components 10. The plurality of detection elements 40 are arranged around the turntable 200 and electrically connected to the turntable 200 respectively. The detection elements 40 are used to detect the fixture 300 located on the corresponding adjustment component 10. Exemplarily, the detection element 40 can be any detection part, detection body, or similar detection block capable of detecting the fixture 300 located on the support member 13 of the adjustment component 10, such as a proximity sensor, photoelectric sensor, etc.
[0052] Thus, through the above settings, multiple detection elements 40 can detect the fixture 300 located on the support member 13 of the corresponding adjustment component 10, determine whether the support member 13 supports the fixture 300, ensure that the support member 13 stably holds the fixture 300 for calibration, and thus ensure the operational stability of the positioning device.
[0053] Please see Figure 1 and Figure 2 In some embodiments, there are two of each of the following: the correction element 23, the correction hole 221, and the receiving hole 301. They correspond one-to-one. In the direction perpendicular to the direction of the pressing element 22 pointing to the turntable element 200, the cross-sectional area of one of the correction elements 23 is larger than that of the other correction element 23. Each correction element 23 is adapted to the corresponding correction hole 221 and the corresponding receiving hole 301.
[0054] Thus, with the above settings, when the calibration component 20 performs calibration on the fixture 300, two calibration components 23 with different cross-sectional areas are respectively inserted into the corresponding calibration hole 221 and the corresponding storage hole 301 to prevent the fixture 300 from being placed in reverse and to ensure that the fixture 300 is placed on the support 13 in the preset orientation, thereby further improving the calibration stability of the calibration component 20.
[0055] Please see Figure 2 In some embodiments, the end of the correction element 23 adjacent to the adjustment component 10 is a cone 231.
[0056] Thus, through the above arrangement, during the process of calibrating the fixture 300 by the calibrator 23, the conical body 231 is inserted into the calibrator hole 221 and the receiving hole 301 before the main body of the calibrator 23, so as to guide the movement direction of the calibrator 23 and ensure that the calibrator 23 is smoothly inserted into the calibrator hole 221 and the receiving hole 301, thereby improving the calibrator efficiency and calibrator accuracy.
[0057] Please see Figure 1 and Figure 3In some embodiments, the turntable 200 has a through hole 201 that extends vertically through the turntable 200 and is coaxial with the center of the turntable 200. The lifting member 21 includes a fixed body 211, a lifting body 212, and a connecting body 213. The fixed body 211 is inserted into the through hole 201, and the lifting body 212 is disposed on and connected to the fixed body 211. One end of the connecting body 213 is connected to the lifting body 212, and the other end of the connecting body 213 is perpendicularly connected to the holding member 22. The connecting body 213 is configured to move closer to or further away from the turntable 200 under the drive of the lifting body 212. Exemplarily, the lifting body 212 can be a cylinder, a servo slide, etc.
[0058] The working process of the above-mentioned calibration device 100 is roughly as follows:
[0059] First, place multiple sets of jigs 300 on the corresponding support members 13 so that the support members 13 can stably support the jigs 300.
[0060] Then, the turntable 200 drives the fixture 300 to rotate in a preset direction so that the clamping member 22 corresponds to the fixture 300 to be corrected;
[0061] Next, the lifting member 21 drives the holding member 22 to press the fixture 300 to the adjusting member 12. The adjusting member 12 drives the supporting member 13 to slide the fixture 300 relative to the turntable member 200 so that the correction hole 221 corresponds to and connects with the storage hole 301 opened on the fixture 300. The correction member 23 is inserted into the correction hole 221 and the storage hole 301 to correct the position and orientation of the fixture 300, so as to achieve quick and accurate correction of the position and orientation of the fixture 300, while simplifying the positioning process of the fixture 300, thereby improving the positioning efficiency and positioning accuracy.
[0062] Finally, the holding member 22 and the calibrating member 23 are released from the calibrated fixture 300, and the turntable member 200 moves the calibrated fixture 300 away and moves another fixture 300 to be calibrated to the underside of the holding member 22 for repeated calibration.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
