[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figures 1 to 4As shown, an anti-sway device for a three-dimensional coordinate measuring machine described in an embodiment of the present invention includes a measuring table 1; an operating component 101 is provided on the top of the measuring table 1, and a measuring component 102 is provided on one side of the operating component 101; a cavity 11 is provided in the middle of the measuring table 1, and a plurality of slide grooves 111 are provided on the top of the measuring table 1, and the slide grooves 111 are communicated with the cavity 11, and cylinders 12 are fixedly connected on both sides of the cavity 11, and one end of the cylinder 12 is fixedly connected to a first slider 13, and one side of the first slider 13 is fixedly connected to a fixed block 14, and one side of the fixed block 14 is hinged with a connecting rod 15, and one end of the connecting rod 15 is hinged to a second slider 16, and the second slider 16 and the top of the first slider 13 are both fixedly connected to a sliding rod 17, and the sliding rod 17 is slidably connected to the slide groove 111, and the top of the sliding rod 17 is fixedly connected to a clamping block 18, and the clamping block 18 is slidably connected to the measuring table 1 to align the workpiece with the measuring table 1. The bottom of the component 102 is placed on the measuring table 1, and the cylinder 12 is started. The cylinder 12 pushes the first slide 13 to slide, causing the fixed block 14 to slide together with the first slide 13, and the fixed block 14 pushes the connecting rod 15 to move, and then pushes the second slide 16 to slide, and finally the slide rod 17 slides together in the slide groove 111, and the movement of the slide rod 17 drives the clamping block 18 to approach the workpiece and clamp the workpiece, and finally the operating component 101 is used to control the measuring component 102 to measure the workpiece; by setting the cylinder 12 to push the first slide 13, and then drive the fixed block 14 to move, causing the fixed block 14 to push the connecting rod 15, and then push the second slide 16, the purpose of achieving the slide rod 17 sliding in the slide groove 111 at the same time can be achieved. In this way, the clamping block 18 can be driven to move toward the workpiece at the same time to clamp the workpiece, reducing the shaking and offset of the workpiece during measurement, and achieving a more accurate effect of the measurement data of the workpiece by the measuring component 102.
[0024] like Figures 3 to 4 As shown, one side of the clamping block 18 is fixedly connected to a fixed plate 2, and one side of the fixed plate 2 is fixedly connected to two damping rods 21. A buffer spring 211 is provided on the outside of the damping rod 21. One end of the buffer spring 211 is fixedly connected to the fixed plate 2. The buffer spring 211 and the damping rod 21 are both connected to the clamping block 18 through. One end of the damping rod 21 is fixedly connected to a shock-absorbing plate 22, and the other end of the buffer spring 211 is fixedly connected to the shock-absorbing plate 22. When the clamping block 18 approaches the workpiece, the damping The vibration plate 22 first contacts the workpiece, and the workpiece squeezes the vibration damping plate 22, causing the damping rod 21 to be compressed, so that the vibration damping plate 22 moves close to the clamping block 18. At the same time, the clamping block 18 is also approaching the workpiece. Under the action of the damping rod 21, the running speed of the clamping block 18 is slowed down to avoid collision. By setting the vibration damping plate 22 and the damping rod 21, in the process of the clamping block 18 approaching the workpiece and clamping it, the vibration damping plate 22 provides a certain buffer for the workpiece, thereby reducing the situation where the clamping block 18 quickly clamps the workpiece and causes damage to the workpiece.
[0025] like Figures 3 to 4 As shown, the two ends of the clamping block 18 are rotatably connected with a clamping plate 3, and the clamping plate 3 is connected to the torsion spring of the clamping block 18. The clamping plate 3 expands the contact area between the clamping block 18 and the workpiece. When fixing a large workpiece, the contact area between the clamping block 18 and the workpiece is too small to stabilize the workpiece. The clamping plate 3 expands the clamping and fixing area of the clamping block 18, increases the clamping capacity of the large workpiece, and improves the stability.
[0026] like Figures 3 to 4 As shown, an elastic rope 4 is fixedly connected to one side of the splint 3, and one end of the elastic rope 4 is fixedly connected to the damping rod 21. The elastic rope 4 is connected to the damping rod 21. When the damping rod 21 is compressed, the damping rod 21 drives the elastic rope 4 to move toward the fixed plate 2. In this process, the elastic rope 4 pulls the splint 3, causing the splint 3 to expand outward, which makes it easier for the splint 3 to clamp and limit the workpiece.
[0027] like Figures 1 to 5 As shown, ventilation pipes 5 are fixedly connected to both sides of the measuring component 102, and an external air pipe 51 is connected to the top of the ventilation pipe 5. The external air pipe 51 is fixedly connected to the measuring component 102 and passes through the measuring component 102. A plurality of air holes 52 are connected to one side of the ventilation pipe 5. The external air pipe 51 is connected to an air pump to introduce gas into the ventilation pipe 5. The air flow passes through the air holes 52 and acts on the surface of the workpiece to clean the dust and impurities on the surface of the workpiece, thereby reducing the influence of dust and impurities on the measurement results of the measuring component 102.
[0028] like Figures 2 to 4 As shown, a buffer pad 6 is provided on one side of the shock-absorbing plate 22, and the buffer pad 6 is fixedly connected to the shock-absorbing plate 22. The clamping block 18 applies a thrust to cause the shock-absorbing plate 22 to squeeze the workpiece to maintain fixation. The buffer pad 6 is made of a flexible material and can protect corners or edges, protect the workpiece, and prevent the corners of the workpiece from being damaged due to squeezing.
[0029] Working principle: align the workpiece with the bottom of the measuring component 102, place it on the measuring table 1, start the cylinder 12, the cylinder 12 pushes the first slider 13 to slide, causing the fixed block 14 and the first slider 13 to slide together, the fixed block 14 pushes the connecting rod 15 to move, and then pushes the second slider 16 to slide, and finally the slide bar 17 slides together in the slide groove 111, the movement of the slide bar 17 drives the clamping block 18 to approach the workpiece and clamp the workpiece, and finally the operating component 101 is used to control the measuring component 102 to measure the workpiece; by setting the cylinder 12 to push the first slider 13, thereby driving the fixed block 14 to move, causing the fixed block 14 to slide, The fixed block 14 pushes the connecting rod 15, and then pushes the second sliding block 16, so that the sliding rod 17 can slide in the sliding groove 111 at the same time, so as to drive the clamping block 18 to move toward the workpiece at the same time, clamp the workpiece, reduce the shaking and offset of the workpiece during measurement, and achieve more accurate data measurement of the workpiece by the measuring component 102. When the clamping block 18 approaches the workpiece, the shock-absorbing plate 22 first contacts the workpiece, and the workpiece squeezes the shock-absorbing plate 22, causing the damping rod 21 to be compressed, so that the shock-absorbing plate 22 moves close to the clamping block 18. At the same time, the clamping block 18 is also approaching the workpiece. Under the action of the damping rod 21, the clamping is slowed down. The block 18 runs at a high speed to avoid collision. By setting a shock-absorbing plate 22 and a damping rod 21, when the clamping block 18 approaches the workpiece and clamps it, the shock-absorbing plate 22 provides a certain buffer to the workpiece, reducing the situation where the clamping block 18 quickly clamps the workpiece and causes damage to the workpiece. The clamping plate 3 expands the contact area between the clamping block 18 and the workpiece. When fixing a large workpiece, the contact area between the clamping block 18 and the workpiece is too small to stabilize the workpiece. The clamping plate 3 expands the clamping and fixing area of the clamping block 18, increases the clamping capacity of large workpieces, and improves stability. The elastic rope 4 is connected to the damping rod 21. When the damping rod 21 is compressed, The damping rod 21 drives the elastic rope 4 to move toward the fixed plate 2. During this process, the elastic rope 4 pulls the splint 3, causing the splint 3 to expand outward, so that the splint 3 can clamp and limit the workpiece. The external air pipe 51 is connected to the air pump to introduce gas into the ventilation pipe 5. The air flow passes through the air hole 52 and acts on the surface of the workpiece to clean the dust and impurities on the surface of the workpiece, thereby reducing the influence of dust and impurities on the measurement results of the measuring component 102. The clamping block 18 applies thrust to cause the shock absorbing plate 22 to squeeze the workpiece to maintain fixation. The buffer pad 6 is made of flexible material, which can protect corners or edges, protect the workpiece, and prevent the corners of the workpiece from being damaged due to squeezing.
