Description
[technical field]
The utility model relates to the laser cutting technique field, relates in particular to laser cutting head focusing locking device.
[background technology]
Laser has high brightness, high directivity, high monochromaticity and high coherence's four characteristics, and laser beam can obtain high energy density after focusing on.At present, laser is widely used in cutting, punching, welding and material modification in industry.But existing laser cutting head is aspect focus adjustment, and on the one hand, because complex structure, the assembly relation complexity between the focusing component causes the assembly period of laser cutting head long, does over again often, and efficient is low; Because the locking mechanism of laser cutting head is difficult for locking, causes cutting focus and walk easily on the other hand, influence is to the cut quality of product.
[utility model content]
The technical problems to be solved in the utility model provides a kind of laser cutting head focusing locking device simple and that locking effect is good that assembles.
The technical scheme that the utility model adopted is:
Laser cutting head focusing locking device, comprise a mirror chamber box, one locking nut, two semicircle limited blocks, one focusing nut, one guide ring, one sliding sleeve and a connecting cylinder, described mirror chamber box bottom stage part is connected with the last groove of described focusing nut, two semicircle limited blocks are around in the groove that is inserted in box bottom stage top, mirror chamber, described semicircle limited block is positioned at focusing nut top, and with the focusing nut fixedly connected, described locking nut is positioned at two semicircle limited block tops, itself and mirror chamber box threaded engagement, connecting cylinder is fixedly connected on the bottom of sliding sleeve, guide ring cooperates with the gathering sill of sliding sleeve, and being fixed on mirror chamber box inwall, sliding sleeve cooperates with the focusing nut thread.
Described laser cutting head focusing locking device also comprises the rotation scale features, and it is fixedlyed connected with the focusing nut.
Described laser cutting head focusing locking device also comprises straight moving scale features, and it is fixedlyed connected with connecting cylinder and/or sliding sleeve.
The internal thread of described locking nut cooperates with the external screw thread of mirror chamber box.
The screw-internal thread fit of the external screw thread of sliding sleeve and focusing nut.
The beneficial effects of the utility model are:
The assembly relation of each parts of device of the present utility model is simple, the assembling of laser cutting head can be finished smoothly, raise the efficiency, when regulating the cutting focus, only need rotation focusing nut to realize, after focusing is finished, the semicircle limited block that is between focusing nut and the locking nut is locked by the rotational lock nut, thereby realize locking to the cutting focus, easy to operate and can not walk because of the loosening cutting focus that cause; Owing to be provided with rotation scale features and straight moving scale features, make the focusing operation have more intuitive.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a partial cutaway schematic of the present utility model.
Fig. 2 is a structure exploded perspective view of the present utility model.
[specific embodiment]
Referring to Fig. 1 and Fig. 2, laser cutting head focusing locking device of the present utility model, comprise a mirror chamber box 1, one locking nut 2, two semicircle limited blocks 3, one focusing nut 4, one guide ring 5, one sliding sleeve 7 and a connecting cylinder 9, described mirror chamber box 1 bottom stage part is connected with the last groove of described focusing nut 4, two semicircle limited blocks 3 are around in the groove that is inserted in box 1 bottom stage top, mirror chamber, described semicircle limited block 3 is positioned at focusing nut 4 tops, and with the focusing nut 4 fixedly connected, described locking nut 2 is positioned at two semicircle limited block 3 tops, itself and mirror chamber box 1 threaded engagement (internal thread of locking nut 2 cooperates with the external screw thread of mirror chamber box 1), connecting cylinder 9 is fixedly connected on the bottom of sliding sleeve 7, guide ring 5 cooperates with the gathering sill of sliding sleeve 7, and be fixed on mirror chamber box 1 inwall, sliding sleeve 7 and focusing nut 4 the threaded engagement screw-internal thread fit of focusing nut 4 (external screw thread of sliding sleeve 7 with).
When rotation focusing nut 4, sliding sleeve 7 moves up and down, and the drive connecting cylinder 9 of fixedlying connected with sliding sleeve 7, owing on the connecting cylinder 9 cutting nozzles is installed, has played the effect of focusing.
In order to prevent that cutting focus changes suddenly, the utility model provides the function of focusing locking, the rotational lock nut 2 to the right, locking nut 2 lower surfaces will combine with semicircle limited block 3 upper surfaces, the two sides surface roughness that locking nut 2 and semicircle limited block 3 are relative is bigger, then semicircle limited block 3 is locked, and then focus can not moved again; Rotational lock nut 2 and semicircle limited block 3 can be focused again to the right.
In addition, have more intuitive in order to make the focusing operation, laser cutting head focusing locking device of the present utility model also comprises rotation scale features 6, and it is fixedlyed connected with focusing nut 4; Laser cutting head focusing locking device also comprises straight moving scale features 8, and it is fixedlyed connected with sliding sleeve 7, follows sliding sleeve 7 and moves up and down, and need point out, directly moving scale features 8 can also be fixedlyed connected with connecting cylinder 9, perhaps all fixedlys connected with connecting cylinder 9, sliding sleeve 7.
