Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping device technology, and in particular to a laser positioning clamping device for automatic fixed-length cutting of steel wire. Background Technology
[0002] Precision wire cutting technology is widely used in industrial production, particularly in wire processing, prefabricated building components, automotive parts manufacturing, and hardware products. In these applications, steel wires need to be precisely cut to specific lengths to meet the requirements of subsequent processing or assembly.
[0003] Currently, existing automated wire length cutting technology mainly uses optical sensing distance measurement, which measures the moving distance of the wire in real time through sensors. Specifically, during the continuous release of the wire, the device's distance measurement method records the length of the wire's movement. When the cumulative length reaches a preset value, the device's cutting method cuts the wire, and then continues to measure the length of the next section of wire and repeat the cutting process.
[0004] While the aforementioned technical solutions can achieve continuous automated operation, improve production efficiency, and reduce manual intervention, in practical applications, since steel wire is usually stored in coils, a certain degree of curvature or bending is unavoidable during the unwinding process, causing slight swaying or deformation during movement. This non-linear motion affects the accuracy of the photosensitive distance, causing a deviation between the measured value and the actual unwound wire length, ultimately affecting cutting accuracy, resulting in some wire segments not meeting the required length, and even impacting the quality of subsequent processing.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Example: A laser positioning and clamping device for automatic fixed-length cutting of steel wire, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the device includes: a base 1; a first mounting plate 2 fixedly installed on the left end of the base 1; a cutter 3 fixedly installed on the first mounting plate 2 for cutting steel wire 31; and a collection box 32 slidably installed on the right end of the base 1 for collecting the cut steel wire 31. The clamping device also includes: a wire guide 33 fixedly installed on the first mounting plate 2 for straightening the steel wire 31, the wire guide 33 being located to the left of the cutter 3; a first electric slide rail 4 fixedly installed on the right end of the base 1, the first electric slide rail 4 being located on the front and rear sides of the collection box 32; and a movable plate 5 slidably installed on the base 1, the movable plate 5 being fixed to the control end of the first electric slide rail 4. Rail 4 controls the left and right movement of the moving plate 5, which passes over the collection box 32 during movement; a laser rangefinder 6 is fixedly installed on the rear side of the moving plate 5, which measures the distance between itself and the cutter 3 in real time; a second electric slide rail 7 is fixedly installed on the moving plate 5; two clamping plates 8 are slidably installed on the moving plate 5, and the two clamping plates 8 are fixed to the control end of the second electric slide rail 7, which controls the two clamping plates 8 to move closer and clamp the fixed steel wire 31; a controller 10 is fixedly installed on the cutter 3, and the controller 10 is electrically connected to the cutter 3, the first electric slide rail 4, the second electric slide rail 7, and the laser rangefinder 6.
[0022] First, the steel wire 31 is passed sequentially through the gap between the wire organizer 33, the cutter 3, and the two clamping plates 8. The wire organizer 33 is responsible for straightening the steel wire 31. Then, the second electric slide rail 7 is activated, and the clamping plates 8 are used to clamp and fix the steel wire 31. The controller 10 is used to set the specific length of the steel wire 31 to be cut. After completion, the moving plate 5 is moved to the right, and the steel wire 31 is moved to the right. When the laser rangefinder 6 detects that the distance between it and the cutter 3 has reached the preset length of the steel wire 31, the laser rangefinder 6 promptly sends a signal to the controller 10. After receiving the signal, the controller 10 quickly controls the cutter 3 to cut the steel wire 31, and at the same time controls the clamping plates 8 to release the steel wire 31. At this time, the cut steel wire 31 will fall naturally into the collection box 32. Finally, the moving plate 5 is moved to the left to reset. By repeating the above operation process, the continuous cutting operation of the steel wire 31 can be achieved.
[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this clamping device also includes: a pressure sensor 9 fixedly mounted on one of its clamping plates 8, the pressure sensor 9 being used to sense the contact pressure with the steel wire 31, the position of the pressure sensor 9 in contact with the steel wire 31 being aligned with the position of the laser emitting end of the laser rangefinder 6, and the controller 10 being electrically connected to the pressure sensor 9; a second mounting plate 11 fixedly mounted on the first mounting plate 2, the second mounting plate 11 being disposed between the cutter 3 and the wire rack 33; a motor 12 fixedly mounted on the second mounting plate 11, the motor 12 being electrically connected to the controller 10; a drive roller 13 rotatably mounted on the second mounting plate 11, the output end of the motor 12 being coaxially fixed to the drive roller 13 using a coupling; an adjusting frame 15 slidably mounted on the second mounting plate 11; a driven roller 14 rotatably mounted on the adjusting frame 15, the driven roller 14 cooperating with the drive roller 13 to transport the steel wire 31 to the right; and an adjusting rod 16 rotatably mounted on the second mounting plate 11, the adjusting rod 16 being threadedly mounted to the adjusting frame 15.
[0024] While setting the cutting length of the steel wire 31 using the controller 10, the moving distance of the moving plate 5 must be longer than the cutting length of the steel wire 31. This is to provide sufficient space for the steel wire 31 so that it can fall smoothly into the collection box 32 after being cut. Secondly, rotating the adjusting rod 16 controls the up-and-down movement of the adjusting frame 15, thereby adjusting the distance between the driving roller 13 and the driven roller 14. This allows them to adapt to steel wires 31 of different sizes and maintain a close fit with the steel wire 31 at all times, ensuring the stability of the steel wire 31 during transport. Then, the steel wire 31 is sequentially passed through the wire guide frame 33, the gap between the driving roller 13 and the driven roller 14, the cutter 3, and the gap between the two clamping plates 8. The motor 12 is then started, controlling the driving roller 13 to rotate and the driven roller 14 to rotate under the action of the steel wire 31, thus transporting the steel wire 31 to the right. When the end of the steel wire 31 moves to contact the pressure sensor 9, the pressure sensor 9 sends a signal to the controller 10. Upon receiving the signal, the controller 10 quickly controls the second electric slide rail 7 to run, controlling the two clamping plates 8 to clamp and fix the wire. The steel wire 31 is moved to the right by the moving plate 5, which is controlled to move the steel wire 31 simultaneously. During this process, special attention must be paid to ensuring that the speed of the moving plate 5 moving the steel wire 31 matches the speed of the moving roller 13, to ensure the continuity and stability of the steel wire 31 transport. When the cutter 3 completes the cutting operation of the steel wire 31 and the clamping plate 8 releases the steel wire 31 simultaneously, the moving plate 5 continues to move until its preset position, ensuring that the steel wire 31 falls completely into the collecting box 32. Once the moving plate 5 reaches its preset position, the moving plate 5... The device moves to the left to reset. During this process, the moving plate 5 should return to its original position as quickly as possible. This process must ensure that the position of the wire 31 pushed by the drive roller 13 does not exceed the position of the pressure sensor 9 after the moving plate 5 has returned to its original position. Alternatively, the motor 12 can be set to stop intermittently, with the interval between stops set to the time required for the moving plate 5 to fully return to its original position. After the moving plate 5 has fully returned to its original position, the motor 12 drives the drive roller 13 to transport the wire 31 to the right until the end of the wire 31 contacts the pressure sensor 9 again. Repeating this cycle achieves automatic feeding of the wire 31. Combined with the precise cutting function of this clamping device, it automates precise cutting operations, thereby further improving processing efficiency.
[0025] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, this clamping device also includes: an auxiliary wheel 17 rotatably mounted on the base 1, through which the collection box 32 rolls in contact with the base 1, enabling convenient loading and unloading of the collection box 32, reducing operational labor, and ensuring a tight fit between the collection box 32 and the base 1, effectively preventing the steel wire 31 from falling into the gap between them, thus preventing collection difficulties caused by the steel wire 31 getting stuck in the gap; and a protective pad 18 fixedly mounted on the drive roller 13 and the driven roller 14, which is used to prevent the steel wire 31 from wearing against the drive roller 13 and the driven roller 14 during transportation, thereby extending the service life of the steel wire 31, the drive roller 13 and the driven roller 14, reducing the maintenance cost of this clamping device, and ensuring the quality of the steel wire 31. The rubber pad 19, which is fixedly installed on the clamping plate 8, not only increases the contact friction coefficient between the clamping plate 8 and the steel wire 31, improving clamping stability, but also has the ability to deform elastically, allowing the clamping plate 8 to adapt to steel wires 31 of different sizes, ensuring stable clamping of the steel wire 31, and ensuring the positional accuracy and stability of the steel wire 31 during processing; the guide ring 20, which is fixedly installed on the wire management frame 33, has an arc-shaped contact surface, which can help the steel wire 31 pass through the wire management frame 33 conveniently and smoothly, reducing the resistance of the steel wire 31 when passing through the wire management frame 33, and preventing the steel wire 31 from affecting the subsequent processing flow due to jamming or bending, thereby improving the operating efficiency and processing quality of this clamping device.
