7 are horizontally disposed in left-right direction, and leading screw 7 is connected through a screw thread with feed screw nut seat 6, and are equipped with fastening in the right end of leading screw 7
Bar 8.It is described to be connected with dynamic pressure plate 10 by the first rotation axis 9 with the left end of leading screw 7.Cutting assembly includes cutting sheet 11 and driving
Motor（It is not shown in figure）.
As shown in Fig. 2, the angle positioning includes pointer 2, the second rotation axis 3, clam member 5,12 He of angle scale
Connecting bracket 15；The connecting bracket 15 is fixed on pedestal 1 by two positioning bolts and is located at the left side with dynamic pressure plate 10,
The upper level board 15a that is mutually parallel and lower horizontal board 15b is equipped on the right flank of connecting bracket 15, on this level board 15a and
Lower horizontal board 15b forms hinged seat.The left surface of the clam member 5 is equipped with and is horizontally mounted a 5a, this is horizontally mounted a 5a
It is hinged on by the second rotation axis 3, nut on the hinged seat of connecting bracket 15.The upper level board 15a is equipped with perpendicular to institute
The clamping screw 14 of level board 15a is stated, and rocking handle 4 is equipped in the upper end of clamping screw 14, the clam member 5 can be by this
Clamping screw 14 is locked on hinged seat.Described be horizontally mounted on a 5a is additionally provided with limiting slot 5b, first caging bolt 13
Lower end through the upper level board 15a and extending into limiting slot 5b.There is angle index, the angle on the angle scale 12
Scale 12 is horizontally arranged on clam member 5；In the present embodiment, the top of the clam member 5 is equipped with card slot 5c, the angle
The left end of disk 12 is interference fitted with card slot 5c.The lower end of the pointer 2 is fixed in connecting bracket 15, and the upper end of pointer 2
Positioned at the top of angle scale 12.
The present invention realizes 5 angle change of clam member by rotation of the clam member 5 around the second rotation axis 3, passes through fastening
Pressing plate 5 is engaged with angle scale 12, pointer 2 realizes that cutting angle is accurately positioned, and clam member 5 is realized by clamping screw 14
Release and locking realize that cutting angle is quickly adjusted by rocking handle 4, pass through the first caging bolt 13 and ensure cutting safety.Tight
After solid pressure plate 5 is completed angular adjustment and locked, section bar 17 is put on substrate 1, section bar 17 is compressed with dynamic pressure plate 10, completes section bar
17 angles are fixed, and are finally cut, angle section bar needed for acquisition.The present invention possesses flexible rotation, makes simple, operation side
Just the features such as, cutting accuracy is high, not only ensure that the quality of cutting section bar 17, but also improve cutting efficiency, ensure that cutting
Safety.
Shown in Fig. 2, core component of the invention is angle positioning, it, which can be realized, is quickly accurately positioned cutting angle
Degree.During work, 15 opposite base of connecting bracket, 1 remains stationary.Before cutting, clamping screw 14 is unscrewed by rotating arm 4, is being locked
Tight bolt 16 is not compacted in the state of clam member 5, clam member 5 is rotated around the second rotation axis 3, at this time angle scale 12
It is rotated with together with clam member 5, pointer 2 is fixed in connecting bracket 15, and clam member 5, angle scale 12 and pointer 2 are formed relatively
Rotation when pointer 2 is when signified scale is consistent with required cutting angle on angle scale 12, is stopped rotating.At this point, it is shaken by rotation
Arm 4 locks clamping screw 14, stops clam member 5 admittedly using the frictional force between clamping screw 14 and clam member 5.Due to base
The influence of the size and cutting drive assembly arrangement etc. of seat 1, cutting angle can only be chosen within the specific limits, therefore in clam member
The 5 limiting slot 5b for being horizontally mounted seat and being provided with arc, this limiting slot 5b and the second rotation axis 3 are concentric, caging bolt 13 and /V
Slot 5b coordinates, and position-limiting action is played when clam member 5 rotates to extreme position, ensures cutting safety.Adjusting fastening pressure
After the angle of plate 5, it would be desirable to the section bar 17 of cutting is put to pedestal 1, rotational fastener bar 8, leading screw 7 by with feed screw nut seat 6
Cooperation can realize advance with retreating, and leading screw 7 drives to advance with dynamic pressure plate 10, continues after section bar 17 is touched with dynamic pressure plate 10
Rotational fastener bar 8, at this moment leading screw 7 can drive rotates with dynamic pressure plate 10 around the first rotation axis 9, continue to increase with dynamic pressure plate 10 with
The contact area of section bar 17, constantly driving are with dynamic pressure plate 10 until it completely attaches to and compress with section bar 17, by clam member
5th, it is fixed with the frictional force between dynamic pressure plate 10 and section bar 17.At this point, the angle positioning of section bar 17 has been completed, finally in base
Seat 1 is cut with being completed under the cooperation of cutting sheet 11, and pedestal 1 need to have enough height, prevent cutting sheet 11 in cutting process with
Ground contacts.
As shown in figure 3, the operating procedure that the cutting of section bar 17 is carried out using the present invention is as follows：Cutting required for choosing first
Then section bar 17, Cutting Length needed for measurement are unscrewed clamping screw 14 with rocking handle 4, rotational fastener pressing plate 5 adjusts thereon
Angle scale 12, the numerical value for making pointer 2 indicated on angle scale 12 is consistent with required 17 cutting angle of section bar, tightens locking at this time
Bolt 14 carries out locking, completes cutting angle positioning.Complete this step after, reversely rotate anchorage bar 8, driving leading screw 7 drive with
Dynamic pressure plate 10 moves back to the right, until can section bar 17 be smoothly placed on pedestal 1, at this time places measured section bar 17
On pedestal 1, it is placed in clam member 5 and between dynamic pressure plate 10, adjusts Cutting Length, then rotate clockwise anchorage bar 8 and adjust
Section leading screw 7 drives and advances to the left with dynamic pressure plate 10, until section bar 17 to be cut is compressed with dynamic pressure plate 10, so far section bar 17
It has mixed up cutting angle and length and has fastened, last operation driving motor drives cutting sheet 11 to be cut, and obtains institute
Need interface angle steel.
