[0031] like Figure 1-5 As shown, the utility model provides a multi-station rotary measuring device, which includes a machine table 1, and a carrying plate 11 is installed on the top surface of the machine table 1; a driving unit 2, including an X-axis driving mechanism 20, a Y-axis driving mechanism 21 and a Z-axis driving mechanism 22, the Y-axis driving mechanism 21 is installed on the machine table 1, the X-axis driving mechanism 20 is movably mounted above the Y-axis driving mechanism 21, and the Z-axis driving mechanism 22 is connected to the movable end of the X-axis driving mechanism 20; a measuring unit 3 is movably connected to the Z-axis driving mechanism 22 along the Z-axis direction for measuring the workpiece; a rotating mechanism 4 is installed on the upper end surface of the carrying plate 11, and includes a fixed frame 40 and a plurality of rotating fixtures 42 arranged in the fixed frame 40 for placing the workpiece, one end of the plurality of rotating fixtures 42 is respectively rotatably connected to a bracket on one side of the fixed frame 40, and the other end thereof is respectively connected to a rotating assembly 41, and the rotating assembly 41 is used to drive the rotating fixture 42 to rotate.

[0032] The utility model provides a multi-station rotary measuring device. When performing workpiece measurement operations, the workpieces to be measured are placed on four rotary jigs 42 respectively. The two groups of measuring components 30 are driven by the driving unit 2 to move to the top of two of the rotary jigs 42 for measurement. At this time, the workpieces that have not been measured or have been measured on the other two rotary jigs 42 can be loaded and unloaded, thereby improving the measurement efficiency and practicality of the device. On the other hand, after the measuring component 30 measures one side of the workpiece, the rotating jig 42 is driven to flip by the rotating component 41 to measure the other sides of the workpiece, so that the multi-station rotary measuring device can measure the workpiece in multiple directions, reducing the cost of manually transferring the workpiece and improving the measurement efficiency.

[0033] Specifically, such as Figure 1 and Figure 2As shown, the X-axis drive mechanism 20, the Y-axis drive mechanism 21 and the Z-axis drive mechanism 22 all include a drive motor and a screw connected to the output end of the drive motor, wherein the Y-axis drive mechanism 21 is arranged on the upper end surface of the machine 1 along the Y-axis direction of the machine 1, and Y-axis sliding assemblies are respectively installed on both sides of the upper end of the machine 1. The Y-axis sliding assembly includes a slide rail installed on the machine 1 parallel to the Y-axis drive mechanism 21 and a slider matching the slide rail. A movable cross plate 12 is installed on the sliders of the two sets of Y-sliding assemblies; the X-axis drive mechanism 20 is mounted on the movable cross plate 12 along the X-axis direction, and the cross plate 12 is driven to move by the Y-axis drive mechanism 21, thereby driving the X-axis drive mechanism 20 along the Y-axis direction. The Z-axis drive mechanism 22 is mounted on the base plate 32 along the Z-axis direction, and a group of Z-axis sliding assemblies parallel to the Z-axis drive mechanism 22 are provided on both sides of the Z-axis drive mechanism 22. The measuring unit 3 is mounted on the slider of the axis sliding assembly and is rotatably connected to the screw rod of the Z-axis drive mechanism 22. The side of the base plate 32 away from the measuring unit 3 is estimated to be connected to the moving end of the X-axis drive mechanism 20. The measuring unit 3 can be driven to move in the X-axis, Y-axis and Z-axis directions through the X-axis drive mechanism 20, the Y-axis drive mechanism 21 and the Z-axis drive mechanism 22, so that the multi-station rotary measuring device can perform more accurate measurement of the workpiece on each rotating fixture 42.

[0034] Further, such as Figure 3 As shown, the measuring unit 3 includes a movable plate 31 and two sets of measuring components 30 fixed in parallel on the movable plate 31. The movable plate 31 is provided with an upper bracket 310 and a lower bracket 311 for mounting the measuring components 30. The measuring component 30 includes a telecentric lens 301, a zoom lens 302 and a laser module 303. The upper and lower ends of the telecentric lens 301 are fixedly mounted on the upper bracket 310 and the lower bracket 311 respectively. The zoom lens 302 and the laser module 303 are fixedly mounted in parallel on the lower bracket 311. Large-scale measurement is achieved through the telecentric lens 301, and the automatic zoom is achieved through the automatic zoom. The lens 302 realizes small-size measurement, and the laser module 303 realizes the measurement of parameters such as thickness and flatness. That is to say, the measuring component 30 can realize the measurement of multiple parameters of the workpiece, meet the requirements of multi-parameter measurement of the workpiece and improve the measurement efficiency. At the same time, the two groups of measuring components 30 arranged in parallel realize the simultaneous measurement of the workpieces on the two groups of rotating fixtures 42. At this time, the rotating fixture 42 without the workpiece or the workpiece that has been measured can be loaded and unloaded, thereby reducing the waiting time during the measurement operation and improving the efficiency of the measurement operation.

[0035] In this embodiment, if Figure 5As shown in the figure, the rotary fixture 42 includes an outer frame support 421 and an inner frame support 422 fixedly connected within the outer frame support 421. That is to say, the rotary fixture 42 is arranged in a "mu" - shaped structure, and a number of air holes 423 for adsorbing workpieces are provided on the inner frame support 422; the air holes 423 are connected to an external negative pressure system, and the workpiece is adsorbed on the rotary fixture 42 through negative pressure, which facilitates the workpiece to be more firmly and stably held during rotation and is not easily dropped; in addition, adjustment holes 424 are respectively provided on the horizontal and vertical frames of the outer frame support 421, positioning blocks 425 are inserted into the adjustment holes 424, multiple positioning blocks 425 can be set according to the specifications of the workpiece, and the position of the positioning blocks 425 on the rotary fixture 42 can also be adjusted through the adjustment holes 424 to be suitable for the positioning of different workpieces. The setting of the positioning blocks 425 improves the accuracy of workpiece loading and makes the measurement accuracy higher.

[0036] Furthermore, as Figure 4 shown in the figure, the rotation assembly 41 includes a rotation motor 410 installed outside the fixed square frame 40 and a rotator 411 installed inside the fixed square frame 40. The output end of the rotation motor 410 is drivingly connected to the rotator 411; a plurality of bearing seats 420 are installed on one inner side of the fixed square frame 40 opposite to the rotator 411. One end of the rotary fixture 42 is rotatably connected within the bearing seats 420, and the other end of the rotary fixture 42 is rotatably connected to the rotator 411; among them, the height of the fixed square frame 40 is higher than the width of the rotary fixture 42, so that the rotary fixture 42 can rotate within the fixed square frame 40; specifically, there are four rotary fixtures 42, and the four rotary fixtures 42 are arranged in sequence along the X - axis direction within the fixed square frame 40. That is to say, the multi - station rotary measurement device in this embodiment can achieve multi - workpiece and multi - azimuth measurement through the structure of two groups of measurement components 30 cooperating with four rotary fixtures 42. On the one hand, it can improve the measurement efficiency. On the other hand, it reduces the labor cost of traditional single - station laser measurement equipment and the cost of multiple devices.

Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above - disclosed technical content as equivalent change equivalent embodiments, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical meaning of the present invention shall fall within the scope of the technical solution of the present invention.
