XR optical detection motion refers to the use of X-ray technology to detect the motion state and trajectory of an object. XR is a non-contact detection method that can monitor and measure the position, speed, acceleration and other motion parameters of an object in real time and accurately.
[0003] In the prior art, optical detection of motion requires the use of a fixture to clamp the object, and a high-precision mechanical arm to change the position of the fixture, that is, to change the position of the object, so as to cooperate with the optical device to detect the motion of the object.
[0004] However, when clamping and fixing objects of different shapes, the corresponding clamps need to be replaced to ensure that the objects are clamped firmly. Replacing the clamps reduces the efficiency of the optical detection movement. Utility Model Content

[0029] Embodiment 1
[0030] This embodiment proposes a motion system based on optical detection, such as Figure 1 As shown, it comprises: a shock-absorbing base 1, a lifting frame 2 and an optical motion detector 7 are fixedly installed on the top of the shock-absorbing base 1, a multi-axis mechanical arm 3 is fixedly installed on the top of the lifting frame 2, a supporting plate 4 is slidably connected to the bottom of the multi-axis mechanical arm 3, and a clamping component 5 is arranged at the bottom of the supporting plate 4. The clamping component 5 clamps the object to be measured, and the position of the clamping component 5 is changed by the multi-axis mechanical arm 3 and the supporting plate 4, thereby changing the position of the object to be measured, and the optical motion detector 7 is used to track and detect the movement of the object to be measured.
[0031] like Figure 3 and 4 As shown, the clamping assembly 5 includes a clamp, a clamp block group 54, a coil spring 55, an extrusion sheet 56 and a pressure sensor 57. The clamp includes a clamp middle block 51, a first hydraulic push rod 52 and a clamp plate 53. The first hydraulic push rods 52 are fixedly installed on both sides of the clamp middle block 51, and the clamp plate 53 is fixedly installed on the end of the first hydraulic push rod 52. The clamp block group 54 is slidably connected to the clamp plate 53, and the pressure sensor 57 is fixedly installed inside the clamp plate 53. The pressure sensor 57 is electrically connected to the first hydraulic push rod 52 through a controller.
[0032] like Figure 2 and 4 As shown, the clamp middle block 51 is fixedly installed at the bottom of the supporting plate 4, the clamp block group 54 adopts a T-shaped structure, and a limit block is fixedly installed inside the clamp plate 53, and the limit block is located on the moving path of the clamp block group 54. The limit block is placed to separate the clamp block group 54 from the inner clamp plate 53. The clamp plate 53 is located on the extension line of the optical motion detector 7, and the height of the clamp plate 53 is the same as that of the optical motion detector 7, so that the optical motion detector 7 can detect the object to be detected at the clamp plate 53.
[0033] Two groups of clamp block groups 54 are provided, and the two groups of clamp block groups 54 are symmetrically arranged in the cavity opened by the fixture, each group has two clamp blocks, and the two groups of clamp block groups 54 are respectively located inside the two clamp plates 53, and the ends of the clamp blocks extend from the clamp plates 53. The two groups of clamp block groups 54 clamp the object to be measured, and the side of the clamp block is fixedly installed with a coil spring 55, and the end of the coil spring 55 is fixedly installed with an extrusion sheet 56, and the side of the extrusion sheet 56 away from the clamp block group 54 contacts the pressure sensor 57. The coil spring 55, the extrusion sheet 56, and the pressure sensor 57 are all arranged in the cavity.
[0034] like Figure 4 As shown, the two clamping block groups 54 are located in the same clamping plate 53, that is, on the same side of the object to be measured. The first hydraulic push rod 52 contracts to move the clamping plate 53 and the clamping block group 54 toward the object to be measured. The clamping block contacts the object to be measured and moves into the clamping plate 53. The clamping block uses the spiral spring 55 and the extrusion sheet 56 to squeeze the pressure sensor 57. When the two clamping blocks of the same group move and the pressure applied to the pressure sensor 57 reaches the set value, the pressure sensor 57 stops contracting the first hydraulic push rod 52 through the controller, and the shape of one side of the object to be measured can be determined. The two clamping block groups 54 cooperate to better fit the object to be measured, making the clamp clamping more stable.
[0035] After the clamping is completed, the extrusion sheet 56 applies elastic force to the clamp block and the spiral spring 55, so that the clamp block group 54 and the spiral spring 55 can be reset. At the same time, the extrusion sheet 56 is used for buffering to prevent the clamp block from directly extruding the pressure sensor 57 and damaging it.
[0036] In this embodiment, the two clamp block groups 54 on one side of the object to be tested move, and the pressure applied to the pressure sensor 57 reaches a set value. When the pressure applied by the two clamp block groups 54 to the pressure sensor 57 reaches the set value, the pressure sensor 57 stops the first hydraulic push rod 52 from moving. At this time, the two clamp block groups 54 are both attached to the side of the object to be tested, better fitting the object to be tested, making the clamp clamping more stable, without the need to replace the clamp, and improving the detection efficiency.
[0037] Embodiment 2
[0038] like Figure 4As shown, based on the first embodiment, this embodiment proposes a motion system based on optical detection, a positioning assembly 6 is fixedly arranged inside the fixture and directly above the clamping block group 54, and the positioning assembly 6 includes a clearance groove 61, a second hydraulic push rod 62 and a positioning block 63. The clamping plate 53 has a clearance groove 61 inside, and the second hydraulic push rod 62 is fixedly installed in the clearance groove 61 inside the clamping plate 53. The end of the second hydraulic push rod 62 is fixedly connected to the positioning block 63, and the pressure sensor 57 is electrically connected to the second hydraulic push rod 62. The positioning block 63 is contacted directly above each clamping block group 54. When the pressure sensor 57 is subjected to a force reaching a set value, the second hydraulic push rod 62 extends to press the positioning block 63 on the clamping block group 54.
[0039] The bottom of the positioning block 63 and the top of the clamping block are both provided with friction lines, which improve the friction force and cooperate with the downward pressure exerted by the positioning block 63 on the clamping block group 54 to fix the position of the clamping block group 54.
[0040] In this embodiment, when the force applied to the pressure sensor 57 reaches a set value, the second hydraulic push rod 62 extends to press the positioning block 63 onto the clamping block group 54, fixing the positions of the multiple clamping block groups 54. The first hydraulic push rod 52 then contracts a certain distance to move the clamping block group 54 to clamp the object to be measured.
[0041] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
