[0032] Compared with the prior art, the laser measurement and positioning device provided in this embodiment is provided with two groups of clamping components 10 and a calibration plate 9 on a placement table 1 for placing the workpiece to be processed, and an origin calibration is provided on the calibration plate 9. When the workpiece to be processed is placed on the placement table 1 and contacts the calibration plate 9, the two groups of clamping components 10 clamp and fix the workpiece to be processed in the middle. At the same time, an adjustment mechanism is provided on the bracket 6 of the placement table 1, and the adjustment mechanism is connected to the laser measurement and positioning component 7. The measurement range of the laser measurement and positioning component 7 can be adjusted by the adjustment mechanism, and the calibration plate 9 and the workpiece to be processed are all included in the measurement range of the laser measurement and positioning component 7. The laser measurement and positioning component 7 identifies the workpiece to be processed and the origin calibration on the calibration plate 9 to form a coordinate point to measure and determine the position of the workpiece to be processed.

[0033] In this embodiment, the laser measurement and positioning component 7 includes existing 3D laser detection products and control components on the market, and can measure dimensions, roundness, etc. When the laser measurement and positioning component 7 detects the origin calibration, the origin calibration point is taken as the origin, and the length direction of the calibration plate 9 is the Y axis to form a coordinate system, and the coordinates of the workpiece to be processed are expressed, thereby locating the precise coordinate position of the workpiece to be processed.

[0034] In this embodiment, the roundness and diameter of disc-like parts can be measured, and the center of the circle can be located to ensure the processing accuracy of the center of the circle. It can also be applied to the positioning and processing of other types of parts.

[0035] In this embodiment, the clamping assembly 10 may be a cylinder or other types of clamps in the prior art, and subsequent processing is facilitated by clamping.

[0036] like Figure 3 to Figure 4As shown, a specific embodiment of the present invention provided on the basis of the first embodiment is as follows: the adjustment mechanism includes a fixed seat 21, a fixed plate 17, a screw 15, a fixed rod 23, a connecting seat 22, a connecting rod 19, a roller 20, and a first spring 18. The fixed seat 21 is connected to the bracket 6, and a through hole 16 is provided on the fixed seat 21; the fixed plate 17 is arranged on the fixed seat 21 and is located next to the through hole 16, and a first inclined surface is provided on the fixed plate 17; the screw 15 is rotatably arranged on the fixed seat 21, and a nut 14 is provided on the screw 15, and the screw 15 is used to drive the nut 14 to move along the length direction of the screw 15; the fixed rod 23 is arranged on the nut At the lower end of the nut 14, the fixing rod 23 extends into the through hole 16; the connecting seat 22 is arranged at the upper end of the nut 14, and a rotating shaft is rotatably provided on the connecting seat 22, and both ends of the rotating shaft extend out of the connecting seat 22, one end of the rotating shaft is connected to the mounting seat 24, and the laser measurement and positioning assembly 7 is arranged on the mounting seat 24; the connecting rod 19 is connected to the other end of the rotating shaft; the roller 20 is rotatably connected to the end of the connecting rod 19 farther away from the rotating shaft, and the roller 20 is rollingly arranged on the first inclined surface; the first spring 18, one end of which is rotatably connected to the connecting rod 19, and the other end of which is rotatably connected to the fixing rod 23, is used to tighten the connecting rod 19 and keep the roller 20 always in contact with the first inclined surface.

[0037] In this embodiment, the roller 20 moves along the first inclined plane, which will push the connecting rod 19 rotatably connected to the roller 20 to rotate, thereby driving the rotating shaft connected to the end of the connecting rod 19 to rotate, and the mounting seat 24 rotates with the rotating rotating shaft to adjust the angle of the laser measurement and positioning assembly 7. Because the mounting seat 24 with the rotating shaft is installed on the nut 14, when the rotating screw 15 drives the nut 14 to move, it will drive the roller 20 to move along the first inclined plane, thereby adjusting the angle of the laser measurement and positioning assembly 7, so as to adjust the detection range of the laser measurement and positioning assembly 7.

[0038] like Figure 1 to Figure 2 As shown, a specific embodiment provided by the present invention on the basis of the first embodiment is as follows: an opening is provided in the middle of the placement table 1, and a receiving plate 2 is rotatably arranged in the opening, two groups of clamping components 10 are respectively located on both sides of the receiving plate 2, a calibration plate 9 is arranged on the receiving plate 2, a supporting plate 3 is provided under the receiving plate 2, the supporting plate 3 is connected to the placement table 1, and a pushing assembly is provided on the supporting plate 3, the pushing assembly is used to push the receiving plate 2 to rotate and fix, and the receiving plate 2 is used to rotate and tilt so that the transferred workpiece to be processed slides to the calibration plate 9.

[0039] In this embodiment, when it is necessary to receive the part to be processed, the push-up assembly pushes the receiving plate 2 to rotate, so that the receiving plate 2 is tilted. When the part to be processed is transferred to the receiving plate 2, because the receiving plate 2 is in a tilted state, the part to be processed slides downward to the calibration plate 9 under the action of gravity and contacts the calibration plate 9. Then the push-up assembly drives the receiving plate 2 to rotate back to the horizontal state, and the two sets of clamping assemblies 10 reinforce the part to be processed, and the laser measurement and positioning assembly 7 can start measurement and positioning.

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: two through grooves are provided on the receiving plate 2, a connecting plate 12 is provided between the receiving plate 2 and the supporting plate 3, the connecting plate 12 is connected to the receiving plate 2, and two mutually parallel bases 25 are provided on the connecting plate 12, the two bases 25 are respectively located below the two through grooves, a cavity is provided in the base 25, the upper end of the cavity is open, a telescopic spring is provided in the cavity, a limit plate 11 is slidably arranged in the cavity, the limit plate 11 is connected to the telescopic spring in the same cavity, the two limit plates 11 can be extended from the two through grooves respectively, and guide slopes are provided on the outer sides of the two limit plates 11, and the two limit plates 11 are used to prevent the workpiece received by the receiving plate 2 from deviating to the left and right during the sliding process.

[0041] In this embodiment, a connecting plate 12 is arranged between the receiving plate 2 and the supporting plate 3, and the connecting plate 12 is connected to the receiving plate 2. Two bases 25 are arranged on the connecting plate 12, and each base 25 is provided with a cavity. A telescopic spring and a limit plate 11 that slides up and down are arranged in each cavity. The telescopic spring is connected to the limit plate 11 and is located below the limit plate 11. Two long through grooves are arranged on the receiving plate 2, and the through grooves correspond to the limit plates 11 one by one. Under the action of the telescopic spring, the limit plates 11 extend from the through grooves, and the outer sides of the two limit plates 11 are provided with guiding inclined surfaces. When the receiving plate 2 and the connecting plate 12 rotate and tilt synchronously, the workpiece to be processed is sent between the two limit plates 11 and slides down under the action of gravity, which can effectively prevent the workpiece to be processed from deviating left and right during the sliding process. When the receiving plate 2 and the connecting plate 12 rotate back to their original positions and maintain a horizontal state, the two groups of clamping assemblies 10 clamp respectively. During the movement, the clamping assemblies 10 first contact the guiding inclined surface of the limiting plate 11 on the same side, which will push the limiting plate 11 back into the through groove, so that the limiting plate 11 does not hinder the clamping of the clamping assembly 10.

[0042] In this embodiment, the receiving plate 2 and the connecting plate 12 are connected via a connecting piece 27 .

[0043] In this embodiment, the width of the through groove on the receiving plate 2 is greater than the thickness of the limiting plate 11. A second slide rail 26 is provided on the connecting plate 12, and the second slide rail 26 is perpendicular to the length direction of the through groove. The two bases 25 are slidably arranged on the second slide rail 26 and can be fixed at any position, so that the distance between the two limiting plates 11 can be adjusted to guide workpieces of different sizes to be processed.

[0044] like Figure 1 to Figure 2 As shown, the present invention provides a specific implementation mode based on the above implementation mode as follows: the ejection assembly is a hydraulic cylinder 13, one end of the hydraulic cylinder 13 is rotatably connected to the connecting plate 12, and the other end of the hydraulic cylinder 13 is rotatably connected to the supporting plate 3.

[0045] like Figure 1 to Figure 2 As shown, the present invention provides a specific embodiment based on the above-mentioned embodiment as follows: a first slide rail 5 is provided on the placement table 1, the first slide rail 5 is parallel to the length direction of the placement table 1, and the legs of the bracket 6 are slidably connected to the first slide rail 5 and can be fixed at any position on the sliding path.

[0046] In this embodiment, a threaded hole is provided on the leg of the bracket 6, and the threaded hole is threadedly connected to the locking bolt 4. When the position of the bracket 6 needs to be adjusted by sliding, the locking bolt 4 is loosened to push the bracket 6 to move along the first slide rail 5; when the bracket 6 needs to be fixed, the locking bolt 4 is tightened so that the locking bolt 4 is pressed against the first slide rail 5.

[0047] like Figure 1 to Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: a linear module 8 is provided on the bracket 6, the length direction of the linear module 8 is parallel to the width direction of the placement table 1, and the slider of the linear module 8 is connected to the adjustment mechanism.

[0049] like Figure 6 to Figure 7 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: a transmission plate 32 is arranged next to the placement table 1, the transmission plate 32 is arranged obliquely, the lower end of the transmission plate 32 is closer to the receiving plate 2, two guide plates 29 are arranged on the transmission plate 32, and a slideway for transporting workpieces to be processed is arranged between the two guide plates 29, one of the guide plates 29 is provided with a first notch 30, and a blocking mechanism is arranged next to the first notch 30, and the blocking mechanism is used to control the workpieces to be processed on the transmission plate 32 to slide down intermittently one by one.

[0050] In this embodiment, an inclined transmission plate 32 is provided on the placement table 1, and the workpiece to be processed on the transmission plate 32 can automatically slide down under the action of gravity. And the extended surface of the transmission plate 32 can pass through the rotation axis of the receiving plate 2. When the receiving plate 2 can be rotated to the same inclination as the transmission plate 32, it is more conducive to the receiving plate 2 to receive the workpiece to be processed. Two guide plates 29 are provided on the transmission plate 32, one of which is provided with a first notch 30, and a blocking mechanism is provided next to the first notch 30. When the parts to be processed on the receiving plate 2 are measured, positioned, and processed, the blocking mechanism prevents the parts to be processed from sliding down. When the processing of the parts to be processed on the receiving plate 2 is completed, the blocking mechanism releases the parts to be processed, and the parts to be processed slide down under the action of gravity, and the receiving plate 2 rotates to an inclined state.

[0051] like Figure 6 to Figure 7 As shown, the present invention provides a specific embodiment based on the above embodiment as follows: the blocking mechanism includes a first seat body 39, a rotating wheel 31, a clamping wheel 35, a connecting frame 36, a clamping claw 38, a tension spring 37, and a release assembly. The first seat body 39 is arranged beside the first notch 30; the rotating wheel 31 is rotatably arranged on the first seat body 39, and no less than three paddles 34 are arranged on the outer wall of the rotating wheel 31. The paddles 34 are evenly arranged along the circumferential direction of the rotating wheel 31, and two paddles 34 can simultaneously extend into the slideway from the first notch 30; the clamping wheel 35 is coaxially connected to the rotating wheel 31 The clamping wheel 35 is provided with a plurality of slots, the number of which is the same as that of the paddle 34; the connecting frame 36 is provided on the first base body 39; the claw 38 is rotatably provided on the first base body 39, and the claw 38 can be clamped into the slot on the clamping wheel 35; one end of the tension spring 37 is connected to the connecting frame 36, and the other end of the tension spring 37 is connected to the claw 38, and the tension spring 37 is used to pull the claw 38 into the slot, keep the rotating wheel 31 stationary, and prevent the workpiece to be processed from sliding down; the release component is used to pull the claw 38 out of the slot, so that the workpiece to be processed can smoothly push the paddle 34 to rotate and slide down under the action of gravity.

[0052] In this embodiment, during the rotation of the rotating wheel 31, two adjacent paddles 34 are inserted into the slideway from the first notch 30 each time, and the part to be processed is located between the two paddles 34 inserted into the first notch 30. Because the rotating wheel 31 and the clamping wheel 35 are coaxially arranged, the rotating wheel 31 and the clamping wheel 35 rotate or stop synchronously. The clamping wheel 35 is provided with a slot, and the claw 38 is rotatably arranged on the first seat body 39. The claw 38 can be clamped into the slot on the clamping wheel 35, and the tension spring 37 pulls the claw 38 to remain in the clamping position. When the claw 38 is clamped into the slot, the rotating wheel 31 and the clamping wheel 35 are both in a stationary state, and the part to be processed is located between the two paddles 34 inserted into the first notch 30 and cannot slide down under the action of gravity. When the release component pulls the claw 38 out of the slot, the part to be processed pushes the rotating wheel 31 to rotate through the paddle 34 under the action of gravity, and the part to be processed continues to slide down through the blocking mechanism. During the rotation of the rotating wheel 31 , the next part to be processed that slides to the blocking mechanism enters between the paddles 34 that are rotated and inserted into the first notch 30 . At this time, the claws 38 return to the state of being stuck in the slot, so that only one part to be processed can flow into the receiving plate 2 .

[0053] like Figure 6 to Figure 7 As shown, a specific implementation scheme provided by the present invention on the basis of the above implementation scheme is as follows: a second notch 28 is also provided on the guide plate 29 provided with a first notch 30, and the first notch 30 and the second notch 28 are arranged in sequence along the path of the slide, and the second notch 28 is closer to the lower exit of the slide, and the release assembly includes a second seat body 33, a linkage rod 41, and a pull rod 40, and the second seat body 33 is arranged next to the second notch 28; the linkage rod 41 is rotatably arranged on the second seat body 33, one end of the linkage rod 41 extends into the slide from the second notch 28, and a connecting rod is provided in the middle of the linkage rod 41; one end of the pull rod 40 is rotatably connected to the claw 38, and the other end is rotatably connected to the connecting rod; when the workpiece to be processed moves down the slide to the linkage rod 41 and pushes the linkage rod 41 to rotate, the pull rod 40 pulls the claw 38 out of the slot, and the paddle 34 on the clamping wheel 35 releases the next workpiece to be processed.

[0054] In this embodiment, along the sliding path of the workpiece to be processed, a second notch 28 is also provided on the guide plate 29 provided with the first notch 30, and the second notch 28 is located below the first notch 30. In the initial state, under the action of the tension spring 37, the clamping claw 38 is clamped in the clamping groove of the clamping wheel 35, and the clamping wheel 35 and the rotating wheel 31 are in a stationary state and cannot rotate. Because the clamping claw 38 is connected to the linkage rod 41 through the pull rod 40, the clamping claw 38 pulls the linkage rod 41 to rotate upward through the pull rod 40, so that the linkage rod 41 contacts the upper wall of the second notch 28. At the beginning, the claw 38 is manually controlled to disengage from the slot, and the first workpiece to be processed pushes the rotating wheel 31 to rotate through the paddle 34. The claw 38 contacts the circumferential wall of the rotating wheel 31 under the action of the tension spring 37. The next workpiece to be processed slides into the space between the next two paddles 34 as the rotating wheel 31 rotates. At this time, the next slot of the rotating wheel 31 rotates to the claw 38. The claw 38 automatically enters the slot under the action of the tension spring 37. The rotating wheel 31 and the clamping wheel 35 are stationary. When the first workpiece to be processed enters between the first notch 30 and the second notch 28, the second workpiece to be processed is stationary between the paddles 34. As the first workpiece to be processed slides to the linkage rod 41, it will push the linkage rod 41 to rotate under the action of gravity. The linkage rod 41 pulls the claw 38 through the pull rod 40 to overcome the tension of the tension spring 37, so that the claw 38 rotates out of the slot, releasing the second workpiece to be processed and entering between the first notch 30 and the second notch 28, and the first workpiece to be processed is received by the receiving plate 2. By controlling the distance between the second notch 28 and the first notch 30, when the second workpiece to be processed slides between the second notch 28 and the first notch 30, the laser measurement and positioning assembly 7 and the external processing equipment can complete the processing of the first workpiece to be processed. When the second workpiece to be processed slides to the linkage rod 41, it will automatically drive the release of the third workpiece to be processed. This embodiment can realize the automatic intermittent release of the workpiece to be processed without the need for an external power source through structural design, ensuring that the workpiece to be processed automatically flows into the measurement and positioning position.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
