Technical field
The utility model relates to a kind of clamp, refers to especially a kind of clamp of sawing machine.
Background technology
Sawing machine is a kind of equipment that utilizes the saw blade of rotation at full speed tubing to be carried out to cutting on line.In the time that saw blade cuts, need to utilize clamp to clamp tubing, the tubing after cut-out also needs the feeding of clamp clamping tubing.And the clamping of current clamp is generally the left and right sides clamping tubing from tubing, so because the cross sectional shape of tubing is varied, the tubing of some shape after upstream machines moulding, the left and right sides of tubing be held position have many stupefied or other and be not suitable for clamping shape.Now, if still adopt current existing clamp clamping, easily tube surfaces is caused to damage, and also may occur the phenomenon that clamping is skidded, cause the uneven phenomenon of section, affected cut quality.
Utility model content
Technical problem to be solved in the utility model is: a kind of clamp of sawing machine is provided, and this clamp can be optionally from the different azimuth clamping tubing of tubing, and the scope of application of clamp is wider, clamps more firm.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of clamp of sawing machine, comprises rotating base, cooperatively interact clamping the first clamp halfbody of tubing and the second clamp halfbody, clamps power set, locking device, arc chute seat; The chute center line of this arc chute seat is horizontal in the time of normal work; Described rotating base is installed on arc chute seat and by described locking device and locks, and this rotating base can slide along arc chute seat; Described the first clamp halfbody and the second clamp halfbody are installed on rotating base; wherein in the first clamp halfbody and the second clamp halfbody, at least one is slidably mounted on rotating base; described clamping power set are fixed on rotating base, and these clamping power set drive the first clamp halfbody or/and the second clamp halfbody slip is drawn close or separated.
As the preferred scheme of one, described locking device comprise the cell wall outside that is arranged at arc chute seat arc-shaped slot, be slidably mounted on slide block in arc-shaped slot, be fixed on the sleeve on rotating base, the center of this arc-shaped slot overlaps with the center of circle of arc chute seat; Between described slide block and sleeve, lock by locking member.
As the preferred scheme of one, between described rotating base and arc chute seat, be provided with positioner.
As the preferred scheme of one, described positioner comprises radial location part and locating slot, on described rotating base, be provided with radial slot, described radial location part Elastic Sliding is installed in radial slot, and the number of described locating slot is multiple and is arranged at intervals on the cell wall of arc chute seat; The end of described radial location part can be stretched in locating slot.
As the preferred scheme of one, the number of described locating slot be 3 and lay respectively at arc chute seat 0 degree position, 45 degree positions and 90 degree positions.
As the preferred scheme of one, the number of described clamp is two covers and the upstream and downstream that is installed on respectively the saw blade of sawing machine.
Adopt after technique scheme, effect of the present utility model is: because rotating base is to be slidably mounted on arc chute seat, therefore just can regulate the position of rotating base by unclamping locking device, like this, the first clamp halfbody and/or the second clamp halfbody just can drive by clamping power set, the first clamp halfbody and the second clamp halfbody are rotated base drive and have changed clamping direction, so just can preferably clamp direction according to the contour structures of tubing to be cut, not only can guarantee that clamping is very firm, and not damage the outer surface of tubing; After saw blade cutting, the section of tubing is smooth, and this clamp scope of application is very wide.
Again due to described locking device comprise the cell wall outside that is arranged at arc chute seat arc-shaped slot, be slidably mounted on slide block in arc-shaped slot, be fixed on the sleeve on rotating base, the center of this arc-shaped slot overlaps with the center of circle of arc chute seat; Between described slide block and sleeve, lock by locking member, therefore, the locking operation between this structure arc chute seat and rotating base is convenient; It is firm to lock.
Again owing to being provided with positioner between described rotating base and arc chute seat, described positioner comprises radial location part and locating slot, on described rotating base, be provided with radial slot, described radial location part Elastic Sliding is installed in radial slot, and the number of described locating slot is multiple and is arranged at intervals on the cell wall of arc chute seat; The end of described radial location part can be stretched in locating slot, therefore, utilize this positioner can be so that quick locking rotating base, the general selection in position of locating slot is suitable for wide clamping direction position, for example 0 degree, 45 degree and 90 degree positions, when in the process that rotating base slides, just represent that rotating base is rotated in place once keeper enters in locating slot, thereby determined easily and fast the orientation of rotating base.
