Description

Laser cutting elbow fixture

The technical field is as follows:

the utility model relates to the technical field of machining, in particular to laser cutting elbow anchor clamps.

Background art:

at present, current laser cutting equipment can only cut pipe and panel, and cut apart to the elbow, current laser cutting equipment then can't realize, this production that has just restricted the enterprise greatly, for example, the enterprise can't directly purchase 90 return bends and cut into required 2 45 return bends by oneself, can only directly purchase when needing 45 return bends, this manufacturing cost that just makes the enterprise improves greatly.

The utility model has the following contents:

in order to overcome the above problems, the utility model provides a can be to 90 return bends carry out the laser cutting elbow anchor clamps of cutting will be favorable.

For this, the utility model provides a laser cutting elbow anchor clamps, it includes the fixed disk, the slope is fixed in on the center of fixed disk and is used for being connected to the dead lever of laser equipment chuck, thereby and two liang of radial symmetrical arrangement be the cross and distribute four elbow chucking mechanisms in the fixed disk outside, every elbow chucking mechanism includes that positive and negative silk adjusting screw on the fixed disk is fixed to one end, threaded connection is at the adjusting nut on positive and negative silk adjusting screw, be used for the clamping sleeve of the conch wall of centre gripping 90 return bends on one side radial fixation in the dead lever on the other end, wherein, every elbow chucking mechanism still includes locking screw, be provided with the locking screw on the clamping sleeve, this locking screw sets up to can follow the outside adaptation of clamping sleeve to this locking screw and push up the surface of the conch wall of 90 return bends.

The utility model discloses in, can conveniently fix whole anchor clamps to the laser equipment chuck through the dead lever on, thereby adjust the elbow chucking mechanism's through adjusting nut and positive and negative silk adjusting screw length can be fit for the elbow of the different bores of centre gripping to the cooperation of locking screw can follow outside locking elbow through locking screw and the tight screw of clamp sleeve.

Furthermore, the clamping sleeve comprises an inner sleeve wall, an outer sleeve wall and a slot which is arranged between the inner sleeve wall and the outer sleeve wall and used for clamping the shell wall of the 90-degree elbow, and a locking screw hole is formed in the outer sleeve wall.

Through the structure, the shell wall of the elbow (namely the 90-degree elbow) can be clamped in the slot of the clamping sleeve, the inner sleeve wall is enabled to abut against the inner surface of the shell wall of the elbow, the locking screw is enabled to abut against the outer surface of the shell wall of the elbow, and the elbow is locked on the laser cutting elbow clamp.

Still further, the fixing rod is fixed to the center of the fixing plate at an inclination angle of 45 °.

Still further, when the fixing rod is fixed to the chuck of the laser apparatus and the four bend chucking mechanisms are clamped on the wall of the 90 ° elbow, the fixing rod is arranged horizontally, and the center cutting line of the 90 ° elbow is arranged vertically.

Through the structure, when the clamp is clamped on the laser equipment chuck, the fixing rod is horizontally placed, the cutting line is vertically arranged, and therefore the laser tool bit of the laser equipment is convenient to cut. And, through cutting 90 return bends into two 45 return bends, can reduce return bend purchase cost by a wide margin.

These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.

Description of the drawings:

the structure of the present invention, together with further objects and advantages thereof, will be best understood from the following description taken in conjunction with the accompanying drawings, in which like reference characters identify like elements:

fig. 1 is a side view of a laser cut bend fixture according to an embodiment of the present invention;

FIG. 2 is a top view of the laser cut elbow fixture of FIG. 1, but with the fixing rods removed for clarity of the fixing disks and the like;

FIG. 3 is a schematic view of the laser cut elbow clamp of FIG. 1 clamping a 90 elbow pipe in a cut condition;

fig. 4 is an enlarged view of a portion a in fig. 3.

The specific implementation mode is as follows:

the following description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 and 2, the laser cutting bend fixture according to one embodiment of the present invention includes a fixing rod 1 for connecting to a chuck (not shown) of a laser device, a fixing disk 2, and four bend clamping mechanisms which are symmetrically arranged in a radial direction and are distributed in a cross shape outside the fixing disk 2, wherein each bend clamping mechanism includes an adjusting nut 3, a positive and negative adjusting screw rod 4, a clamping sleeve 5, and a locking screw rod 6.

In the present embodiment, as shown in fig. 1 and 2, the fixing lever 1 is fixed to the center of the fixed tray 2 with an inclination of 45 °; one end of the positive and negative wire adjusting screw rod 4 is fixed on the fixed disc 2; the adjusting nut 3 is in threaded connection with the positive and negative thread adjusting screw rod 4; the clamping sleeve 5 is radially fixed on the other end of the positive and negative wire adjusting screw rod 4, and is respectively positioned on two sides of the plane where the fixed disc 2 is positioned with the fixed bar 1; the clamping sleeve 5 is provided with a locking screw hole (not shown) to which a locking screw 6 is arranged to be able to fit from the outside of the clamping sleeve 5.

As shown in fig. 3 and 4, the clamping sleeve 5 includes an inner sleeve wall 51, an outer sleeve wall 53, and a slot 52 between the inner sleeve wall 51 and the outer sleeve wall 53 for clamping a wall 101 of the 90 ° elbow 100; the outer jacket wall 53 is provided with the above-mentioned locking screw holes for accommodating the locking screws 6.

The clamping process of the laser cutting bend fixture of the present embodiment is described with reference to fig. 3 and 4:

clamping the laser cutting elbow fixture on a laser equipment chuck through a fixing rod 1;

the length of the positive and negative screw adjusting screw rod 4 is adjusted by rotating the adjusting nut 3, so that the fixed disc 2 is placed in the inner cavity of the 90-degree bent pipe, and the shell wall 101 of the 90-degree bent pipe 100 is just inserted into the slot 52 of the clamping sleeve 5;

the adjusting nut 3 is continuously rotated to adjust the length of the positive and negative screw adjusting screw rod 4, so that the inner sleeve wall 51 of the clamping sleeve 5 of each elbow clamping mechanism is outwards propped against the inner surface of the shell wall 101;

then screwing the locking screw 6 into the locking screw hole of the outer sleeve wall 53 of the clamping sleeve 5 from the outside towards the shell wall 101 of the 90-degree elbow pipe 100 until the locking screw 6 is pressed against the outer surface of the shell wall 101;

when the locking screws 6 of the four elbow clamping mechanisms are fixed in position, the 90-degree bent pipe is fixed in position, at the moment, the chuck of the laser equipment rotates, the laser tool bit of the laser equipment can vertically cut along the central cutting line L of the 90-degree bent pipe, and the 90-degree bent pipe is cut into two 45-degree bent pipes.

Through the anchor clamps of this embodiment, in enterprise's production process, only need purchase 90 return bends can, a 90 return bends can be cut apart into two 45 return bends to can reduce cost. The following table is a price differential survey of 90 ° bends and 45 ° bends:

model number	Unit price (yuan) of 90 degree elbow pipe	Unit price (yuan) of 45 degree elbow pipe
			DN65	37.5	25
DN80	55	33
			DN100	81	54
DN125	117	73
			DN150	295	206

To the enterprise that has laser cutting, purchase 90 elbows, adopt again the utility model discloses an anchor clamps cut, can reduce enterprise manufacturing cost by a wide margin.
