Description

Technical Field

[0001] This invention relates to the field of precision machining of arc surfaces and spheres, and specifically to a rapid positioning device for the center of a sphere in a spherical laser three-dimensional cutting machine. Background Technology

[0002] When processing arc surfaces and spherical surfaces, precision laser cutting is required. Generally, a spherical laser 3D cutting machine is used for this process. Spherical laser 3D cutting machines have a wide range of applications, including the production of rupture discs in the special safety industry and the processing of globes.

[0003] Under current technology, when using a spherical laser 3D cutting machine, it is impossible to quickly locate the height of the sphere's center, and the equipment sometimes has errors in locating the height of the sphere's center, affecting processing efficiency and processing accuracy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that when using a spherical laser three-dimensional cutting machine, it is impossible to quickly locate the height of the sphere center, and the equipment sometimes has errors in locating the height of the sphere center, which affects the processing efficiency and processing accuracy. To this end, a sphere center rapid positioning device for a spherical laser three-dimensional cutting machine is provided.

[0005] The technical solution adopted by this invention to solve the technical problem is: a spherical center rapid positioning device for a spherical laser three-dimensional cutting machine, comprising: a spherical center positioning slide, a spherical center positioning motor fixedly connected to the top center of the spherical center positioning slide, a positioning inner slide groove opened on one side of the spherical center positioning slide, the output end of the spherical center positioning motor passing through the top of the spherical center positioning slide and fixedly connected to a positioning screw, the end of the positioning screw away from the spherical center positioning motor being rotatably connected to the inner bottom end of the spherical center positioning slide, a positioning slider threadedly connected to the surface of the positioning screw, the positioning slider being slidably connected in the positioning inner slide groove, a positioning connecting block fixedly connected to the end of the positioning slider extending to the opening side of the spherical center positioning slide, a follower slide mounted on the outer side of the positioning connecting block, a cutting head mounted on the upper end of the follower slide, the spherical center positioning motor can drive the height of the cutting head to change until the height position of the cutting head is adjusted to match the height of the spherical center of the arc product, thereby enabling rapid and accurate positioning of the spherical center, ensuring processing efficiency.

[0006] Preferably, a lower side block is fixedly connected to the upper end of the positioning connecting block near the positioning slider. A laser rangefinder is fixedly connected to the upper middle part of the lower side block. An upper side block is fixedly connected to the upper end of the ball center positioning slide on one side of the lower side block. A positioning base block is fixedly connected to the bottom end of the upper side block. When the cutting head height is in the initial state, the distance from the laser emitted by the laser rangefinder to the positioning base block is the reference distance. The laser rangefinder is electrically connected to the main controller. The laser rangefinder can detect the change value of the cutting head height and compare it with the ball center height value. It can determine whether the cutting head movement value is accurate and correct it in time, avoiding the problem of error in positioning the ball center height and improving the processing accuracy.

[0007] Preferably, a normal indicator light is fixedly connected to one side of the upper end of the upper side block, and an abnormal indicator light is fixedly connected to the other side of the upper end of the upper side block. Both the normal indicator light and the abnormal indicator light are electrically connected to the main controller. When the height change value of the cutting head detected by the laser rangefinder is compared with the height value of the ball center, and an error exists, the main controller will transmit a signal to the abnormal indicator light, which will light up to promptly alert the operator to the error. When the data is consistent, the main controller will transmit a signal to the normal indicator light, which will light up, allowing normal cutting to proceed.

[0008] Preferably, a rotary motor is fixedly connected to one side surface of the positioning connecting block relative to the follower slide. The output end of the rotary motor is fixedly connected to the lower end of the follower slide. The rotary motor can drive the cutting head to rotate, and at the same time, the product rotation motor on the product support frame will drive the product to rotate. The two motors work together to cut and process the arc-shaped product along its longitude and latitude.

[0009] Preferably, a follower motor is fixedly connected to the bottom end of the follower slide, and a follower groove is provided on one side of the follower slide. The output end of the follower motor passes through the bottom end of the follower slide and is fixedly connected to a follower lead screw. The upper end of the follower lead screw is rotatably connected to the inner top end of the follower slide. A follower slider is threadedly connected to the surface of the follower lead screw. The follower slider is slidably connected in the follower groove. A follower connecting block is fixedly connected to one end of the follower slider extending to the opening side of the follower slide. A connecting frame is fixedly connected to one end of the follower connecting block opposite the cutting head. The end of the connecting frame is fixedly connected to the top seat of the cutting head by bolts. When precisely adjusting the position of the cutting head, the follower motor is turned on, driving the follower lead screw to rotate. The follower slider on the surface of the follower lead screw moves accordingly, which can change the position of the follower connecting block and the cutting head, facilitating precise adjustment of the cutting head position for cutting.

[0010] The present invention has the following advantages:

[0011] 1. By setting a ball center positioning motor, the height of the cutting head can be changed until the height of the cutting head is adjusted to match the height of the ball center of the arc product. This method can quickly and accurately position the ball center, ensuring processing efficiency.

[0012] 2. By setting a laser rangefinder, the change in the height of the cutting head can be detected and compared with the height of the ball center. This allows for the determination of whether the cutting head movement is accurate and timely corrections can be made. This avoids errors in positioning the ball center height and improves processing accuracy.

[0013] 3. By setting up abnormal and normal indicator lights, when the height change value of the cutting head detected by the laser rangefinder is compared with the height value of the ball center and there is an error, the abnormal indicator light will light up to promptly remind the operator of the error. When the height change value of the cutting head detected by the laser rangefinder is compared with the height value of the ball center and the data is consistent, the normal indicator light will light up, and normal cutting can be performed.

[0014] 4. By setting up a rotary motor, the rotary motor can drive the cutting head to rotate, and at the same time, the product rotation motor on the product support frame will drive the product to rotate. The two motors work together to cut and process the longitude and latitude of the arc-shaped product. Attached Figure Description

[0021] Example

[0022] like Figure 1-2 The device shown is a spherical center rapid positioning device for a spherical laser three-dimensional cutting machine. It includes a spherical center positioning slide 1, a spherical center positioning motor 2 fixedly connected to the top center of the spherical center positioning slide 1, a positioning inner groove 3 opened on one side of the spherical center positioning slide 1, the output end of the spherical center positioning motor 2 passing through the top of the spherical center positioning slide 1 and fixedly connected to a positioning screw 4, the end of the positioning screw 4 away from the spherical center positioning motor 2 being rotatably connected to the inner bottom end of the spherical center positioning slide 1, a positioning slider 5 being threadedly connected to the surface of the positioning screw 4, the positioning slider 5 being slidably connected in the positioning inner groove 3, a positioning connecting block 6 being fixedly connected to the end of the positioning slider 5 extending to the opening side of the spherical center positioning slide 1, a follower slide 7 being installed on the outside of the positioning connecting block 6, and a cutting head 9 being installed on the upper end of the follower slide 7.

[0023] In the current technology, when using a spherical laser 3D cutting machine, it is impossible to quickly locate the height of the sphere center, and the equipment sometimes has errors in locating the height of the sphere center, which affects processing efficiency and processing accuracy. Therefore, a sphere center rapid positioning device for a spherical laser 3D cutting machine is needed.

[0024] In this embodiment, the arc-shaped product to be processed is fixed on the product support frame, and then the height of the ball center is calculated (the formula for calculating the ball center is: height from 0 position to the arc product table surface - ball center radius + arch height = positioning ball center height). Then, the ball center positioning motor 2 is turned on by the main controller. The ball center positioning motor 2 drives the positioning screw 4 to rotate, and the positioning slider 5 on the surface of the positioning screw 4 slides accordingly, so that the height of the positioning connecting block 6 changes. The height of the follower slide 7 and the cutting head 9 change accordingly until the height position of the cutting head 9 is adjusted to match the ball center height of the arc product. Then, the main controller controls the ball center positioning motor 2 to be turned off. In this way, the ball center can be quickly and accurately positioned, ensuring processing efficiency.

[0025] Example 2

[0026] Please see Figure 1 Further improvements were made based on Example 1:

[0027] In order to detect whether the movement value of the cutting head 9 is accurate, the upper end of the positioning connecting block 6 near the positioning slider 5 is fixedly connected to the lower side block 10, the upper middle part of the lower side block 10 is fixedly connected to the laser rangefinder 11, the ball center positioning slide 1 is located on the upper end of the lower side block 10 and is fixedly connected to the upper side block 12, the bottom end of the upper side block 12 is fixedly connected to the positioning base block 13, and the laser rangefinder 11 is electrically connected to the main controller.

[0028] In this embodiment, when the cutting head 9 is in its initial height, the distance from the laser emitted by the laser rangefinder 11 to the positioning base block 13 is the reference distance. After the ball center positioning motor 2 drives the cutting head 9 to move and change its height position, the distance between the laser rangefinder 11 and the positioning base block 13 also changes accordingly. The laser rangefinder 11 transmits the detected data to the main controller. At this time, the difference between the distance detected by the laser rangefinder 11 and the positioning base block 13 and the reference distance is the height change value of the cutting head 9. By comparing the height change value of the cutting head 9 detected by the laser rangefinder 11 with the ball center height value, it can be determined whether the movement value of the cutting head 9 is accurate and corrected in time, avoiding the problem of error in positioning the ball center height and improving the processing accuracy.

[0029] To remind the operator whether the height of the cutting head 9 is accurate, a normal indicator light 14 is fixedly connected to one side of the upper end of the upper block 12, and an abnormal indicator light 15 is fixedly connected to the other side of the upper end of the upper block 12. Both the normal indicator light 14 and the abnormal indicator light 15 are electrically connected to the main controller.

[0030] In this embodiment, when the height change value of the cutting head 9 detected by the laser rangefinder 11 is compared with the height value of the ball center and an error is found, the main controller will transmit a signal to the abnormal indicator light 15, causing the abnormal indicator light 15 to light up, which can remind the operator that there is an error. When the height change value of the cutting head 9 detected by the laser rangefinder 11 is compared with the height value of the ball center and the data is consistent, the main controller will transmit a signal to the normal indicator light 14, causing the normal indicator light 14 to light up, and normal cutting can be performed.

[0031] Example 3

[0032] Please see Figure 1 Further improvements were made based on Example 1:

[0033] To facilitate the cutting and processing of arc-shaped products, a rotary motor 16 is fixedly connected to one side surface of the positioning connecting block 6 relative to the follower slide 7, and the output end of the rotary motor 16 is fixedly connected to the lower end of the follower slide 7.

[0034] During cutting, the rotary motor 16 is turned on, and the output end of the rotary motor 16 rotates, which drives the fixed follower slide 7 to rotate. The cutting head 9 on the upper part of the follower slide 7 rotates accordingly. At the same time, the product rotation motor on the product support frame drives the product to rotate. The two motors work together to cut and process the longitude and latitude of the arc-shaped product.

[0035] Example 4

[0036] Please see Figure 3 Further improvements were made based on Example 1:

[0037] To facilitate the adjustment of the position of the cutting head 9, a follower motor 17 is fixedly connected to the bottom of the follower slide 7. A follower slide groove 18 is provided on one side of the follower slide 7. The output end of the follower motor 17 passes through the bottom of the follower slide 7 and is fixedly connected to a follower screw 19. The upper end of the follower screw 19 is rotatably connected to the inner top of the follower slide 7. A follower slider 20 is threadedly connected to the surface of the follower screw 19. The follower slider 20 is slidably connected in the follower slide groove 18. A follower connecting block 21 is fixedly connected to one end of the follower slider 20 extending to the opening side of the follower slide 7. A connecting frame 8 is fixedly connected to one end of the follower connecting block 21 opposite to the cutting head 9. The end of the connecting frame 8 is fixedly connected to the top seat of the cutting head 9 by bolts.

[0038] When precisely adjusting the position of the cutting head 9, turn on the follower motor 17 to drive the follower lead screw 19 to rotate. The follower slider 20 on the surface of the follower lead screw 19 moves accordingly, which can change the position of the follower connecting block 21 and the cutting head 9, making it convenient to precisely adjust the position of the cutting head 9 for cutting.
