Detailed Description
In order to make the technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is clear that the described embodiments are only a part of the embodiments of the present application, and not an exhaustive list of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Through analysis and research on the prior art, when a high-energy laser beam is focused on the outer surface of one side of the cylinder to cut during laser cutting, theoretically, the surface of the opposite side of the cutting surface of the cylinder is not influenced by the cutting beam. However, at the start of the actual cut, the laser cutting nozzle produces a high energy beam that momentarily breaks down the material, which causes ablative damage to the surface of the wall of the barrel opposite the cut surface of the barrel. Therefore, the invention provides a device for preventing the lower surface of a part from being ablated when the cylindrical part is cut by laser, and solves the problem that the opposite side surface of the cutting surface of the conventional thin-wall cylindrical part is ablated when the cylindrical part is cut by the laser.
The following describes a laser cutting protection device for preventing ablation of the lower surface of a laser-cut thin-wall cylindrical part.
As shown in fig. 1, the apparatus includes: a clamping part and a separating part 2; the clamping part fixes the thin-wall cylinder 1 along the axial direction thereof by means of extrusion, clamping and the like, and keeps the rotating shaft 5 of the thin-wall cylinder 1 in a horizontal state as much as possible; the isolation part 2 is fixed on the clamping part, when the upper surface of the thin-wall cylinder 1 is cut by laser, the isolation part 2 is positioned below the inner part of the thin-wall cylinder 1, and the isolation part 2 is used for isolating high-energy laser beams which instantly penetrate through the upper surface of the thin-wall cylinder 1, so that the lower surface of the thin-wall cylinder 1 is prevented from being damaged by ablation of the high-energy laser beams.
In the protection device of this aspect, the clamping portion may include: a first clamping disk 3 and a second clamping disk 4. When the thin-wall cylinder 1 is fixed, the thin-wall cylinder 1 is horizontally placed, and the thin-wall cylinder 1 is fixed between a first clamping disc 3 and a second clamping disc 4 by means of extrusion, clamping and the like of the first clamping disc 3 and the second clamping disc 4; when fixing, it is necessary to keep the centers of the first holding plate 3 and the second holding plate 4 parallel to the central axis of the thin-walled cylinder 1.
One possible implementation manner is that the first clamping disk 3 and the second clamping disk 4 adopt blocking disks with hollow structures, and the hollow structures can reduce the weight of the clamping disks, so that the weight of the protection device is reduced. The two blocking discs support the inner circle surface of the thin-wall cylinder 1, and the roundness of the thin-wall cylinder during cutting is guaranteed. The two blocking discs support the inner surfaces of the two ends of the thin-wall cylinder 1, so that the roundness error of the cylinder caused by machining deformation is reduced, the rigidity of parts of the thin-wall cylinder 1 is increased, and the cutting precision is improved.
In the protection device of the present disclosure, as shown in fig. 2, the isolation portion 2 is sleeved on the rotating shaft 5, two ends of the rotating shaft 5 are respectively inserted into the central through holes of the first clamping disk 3 and the second clamping disk 4, and the rotating shaft 5 is fixed on the hole wall of the central through hole of the first clamping disk 3 and/or the second clamping disk 4 by the positioning pin 6, so that the rotating shaft 5 can rotate together with the first clamping disk 3 and the second clamping disk 4. When the rotating shaft 5 rotates along with the first clamping disk 3 and the second clamping disk 4, because the isolating part 2 is in smooth surface contact with the rotating shaft 5, the isolating part 2 always treats the lower part inside the thin-wall cylinder 1 due to self gravity, and in this way, the laser beam penetrating through the upper surface of the thin-wall cylinder 1 at the beginning of cutting is blocked, so that the effect of protecting the lower surface of the thin-wall cylinder 1 is achieved.
One possible way to achieve this is that between the two clamping discs inside the thin-walled cylinder 1, the rotating shaft 5 is fixedly connected to the central through hole of the two clamping discs by means of the positioning pin 6 and can rotate with the two clamping discs together with the fixed thin-walled cylinder 1. The partition part 2 assembled on the rotating shaft 5 is in smooth surface contact with the rotating shaft 5, and when the rotating shaft 5 rotates along with the blocking disc, the partition part 2 always processes the inner lower part of the thin-wall cylinder 1 under the action of gravity. As shown in fig. 3, the isolation part 2 is a semi-cylindrical structure, and a suspension groove matched with the rotating shaft 5 is arranged at the central axis of the semi-cylinder. Preferably, the partition 2 is a hollow structure.
In this aspect, the protection device further includes: a support portion for supporting the clamping portion. The support portion includes: a first support mechanism 7 and a second support mechanism 8 provided on a support table 9. When the upper surface of the thin-wall cylinder 1 is cut by laser, the two supporting mechanisms and the second supporting mechanism 8 respectively provide supporting force for the first clamping disk 3 and the second clamping disk 4. Meanwhile, the coaxiality of the thin-wall cylinder 1 during rotation is guaranteed, and tail deflection caused by tail head lowering due to self gravity during rotation is avoided when the cylinder is long, so that the coaxiality of the cylinder during rotation is guaranteed, and the cutting precision is improved.
One possible implementation manner is that the first supporting mechanism 7 may adopt a tail-jacking mechanism, such as the tail of a lathe, which is arranged on the supporting table 9, and the front end of the tail-jacking mechanism is jacked in the central through hole of the first clamping disc 3 to support the first clamping disc 3 in a clamping manner; the second supporting mechanism 8 may adopt a three-jaw chuck fixed on the supporting platform 9, and the second clamping disk 4 is clamped by the three-jaw chuck, so as to support the second clamping disk 4. Specifically, the second clamping disk 4 is clamped and fixed through a three-jaw chuck and can rotate along with the rotation of the three-jaw chuck, and the first clamping disk 3 is propped by a tail jacking mechanism; the supporting parts are used for supporting and fixing the two clamping discs, so that tail deflection caused by tail head lowering caused by self gravity when the thin-wall cylinder 1 is long is effectively avoided, coaxiality of the thin-wall cylinder 1 during rotation is guaranteed, and cutting precision is improved.
The present solution is further illustrated by the following examples.
Examples
Example 1
As shown in fig. 1, the present embodiment provides a laser cutting protection device for preventing ablation of the lower surface of a laser-cut thin-walled cylinder part, which comprises: the device comprises a first clamping disk 3, a second clamping disk 4, a partition part 2, a rotating shaft 5, a first supporting mechanism 7, a second supporting mechanism 8 and a supporting platform 9.
When the thin-wall cylinder 1 is subjected to laser cutting, the inner circular surfaces at the two ends of the thin-wall cylinder 1 are supported by the two clamping discs at the two ends, so that the roundness of the thin-wall cylinder during cutting is ensured. The second clamping disk 4 is mounted on a three-jaw chuck fixed on the supporting seat, so that the cylinder can rotate under the action of the three-jaw chuck to realize circumferential cutting. The front top end of the tail jacking mechanism on the supporting seat jacks into the central through hole of the first clamping disc 3, so that the phenomenon that the thin-wall cylinder 1 is lowered at the tail end due to the action of self gravity is avoided, and the coaxiality of the thin-wall cylinder 1 during rotation is ensured. As shown in fig. 2, a rotating shaft 5 is arranged between the two clamping discs inside the thin-walled cylinder 1, and the rotating shaft 5 is connected with the hole wall of the central through hole of the second clamping disc 4 through a positioning pin 6 and can rotate together with the second clamping disc 4 and the thin-walled cylinder 1. The isolating part 2 sleeved on the rotating shaft 5 is in smooth surface contact with the rotating shaft 5. When the rotating shaft 5 rotates along with the clamping part, the upper isolation surface of the isolation part 2 is always kept at a horizontal position due to the self gravity action of the isolation part 2, and high-energy laser beams penetrating through the upper surface of the thin-wall cylinder 1 at the beginning of cutting are blocked, so that the lower surface of the thin-wall cylinder 1 is protected.
Before laser cutting is carried out on the thin-wall cylinder 1, the second clamping disc 4 is installed on the three-jaw chuck, one end of the rotating shaft 5 is installed in a central through hole of the second clamping disc 4, and the rotating shaft 5 is fixedly connected with the second clamping disc 4 through the positioning pin 6. Then, the small circular groove of the isolation part 2 is sleeved on the rotating shaft 5, the isolation part 2 and the rotating shaft 5 do not need to be fixed, and the isolation part 2 can rotate relative to the rotating shaft 5 under the gravity action of the self-counterweight circular arc; when the rotating shaft 5 rotates, the isolation plane of the isolation part 2 can swing slightly, but keeps horizontal basically, and the requirement of isolating the laser beam is met. Further, a layer of grease may be applied to the outer surface of the shaft 5 to reduce friction with the partition 2. The isolation plane of the isolation part 2 is made larger as much as possible under the condition that the rotation of the rotating shaft 5 is ensured and the interference with the inner wall of the thin-wall cylinder 1 is avoided, so that the isolation effect area and the isolation effect of the isolation plane are better. The partition 2 may be bent using a non-ferrous metal plate having a high reflection action to the cutting laser beam. Then, one end of the thin-wall cylinder 1 is sleeved on the step of the second clamping disc 4, the first clamping disc 3 is used for propping against the other end of the thin-wall cylinder 1, and the inner circular surface of the other end of the thin-wall cylinder 1 is supported. The central through hole of the first clamping disc 3 is sleeved on the other end of the rotating shaft 5; subsequently, the center through hole of the first clamping disk 3 is tightly pressed by using the tip of the tail-tip mechanism. The whole mechanism is fixed on the supporting seat. After the thin-wall cylinder 1 is fixed, the laser cutting head 10 starts to cut;
after the cutting is finished, the tail jacking mechanism 7 is moved away, and after the first clamping disc 3 is taken down, the thin-wall cylinder 1 which is finished in cutting can be taken down, and the next thin-wall cylinder can be continuously installed for cutting.
According to the scheme, the situation that the laser beam breaks through the cutting surface to cause ablation on the side surface when the thin-wall cylindrical part is cut by the laser can be effectively solved, and the cutting quality is improved. Compared with the prior art, the concrete effect of this scheme is as follows:
1) the two clamping discs support the inner surfaces of the two ends of the thin-wall cylinder, so that the roundness error of the thin-wall cylinder caused by machining deformation is reduced, the rigidity of the thin-wall cylinder is increased, and the cutting precision is improved;
2) the thin-wall cylinder is clamped on a three-jaw chuck which is arranged on a supporting seat and can rotate through a second clamping disc, the first clamping disc tightly supports the thin-wall cylinder through a tail supporting mechanism arranged on the supporting seat, and tail deflection caused by tail head lowering generated by self gravity when the thin-wall cylinder is long can be avoided, so that the coaxiality of the thin-wall cylinder during rotation is ensured, and the cutting precision is improved;
3) the isolating part which is arranged between the two clamping discs through the rotating shaft and can rotate freely can keep the isolating surface on the isolating part to be always kept horizontal under the action of the self gravity of the isolating part when the thin-wall cylinder and the rotating shaft 5 rotate, so that the lower surface of the thin-wall cylinder is protected from being ablated by penetrating laser beams, and the surface quality of the thin-wall cylinder during laser cutting is ensured.
It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it will be obvious to those skilled in the art that other variations or modifications may be made on the basis of the above description, and all embodiments may not be exhaustive, and all obvious variations or modifications may be included within the scope of the present invention.
