Abstract
The utility model relates to a multifunctional telescopic arm for hacksaw frames, which is composed of front and rear arms whose sections form a [-shaped. The upper parts of the front and rear arms are respectively provided with an outer ring in which localizers are arranged. Lower parts of the front and rear arms are respectively provided with a square hole. The utility model has the advantages that the multifunctional telescopic arm for hacksaw frames can overcome the defects of the existing hacksaw frame, can cause the existing saw frame to regulate the longitudinal distance of the saw frame to implement wide material sawing and cutting, to saw and cut out the required shape in the middle of the material, can use a whole saw blade particularly, can work in some special occasions such as narrow places, the 'dead-zone' position of machines. The utility model has the advantages of flexible and practical use, and increased work efficiency.
Description
The utility model relates to the multi-functional telescopic arm of hacksaw frame of a kind hardware ﹠ tools class.
Existing hacksaw frame changes horizontal span and sawing direction only, can not regulate fore-and-aft distance, therefore can not implement wide material sawing, can not go out the shape of needs in material centre sawing.Complete saw blade can only be used in addition, the still sharp and saw blade that fractures of saw sword can not be utilized.Moreover to narrow place, " dead band " position of some facility can not operation.Above-mentioned shortcoming is made troubles in making repair work and the waste of material (saw blade).
The purpose of this utility model is to overcome the deficiency of existing product and a kind of fore-and-aft distance that can adjustable hack saw frame is provided; Can make the saw blade that fractures on existing hacksaw frame, continue to use; Can be at the multi-functional telescopic arm of the hacksaw frame of narrow local operation.
The utility model is achieved in that the multi-functional telescopic arm of a kind of hacksaw frame is made up of forearm, postbrachium, and it is characterized in that: forearm and postbrachium cross section are the Contraband type, on top separately one outer ring are arranged, and are provided with in the outer ring
The locator of shape, the bottom is provided with square hole, locator is connected with the outer ring by a circle and can does 270 ° of rotations, respectively there is a through hole one side top and the bottom of forearm, there are a nut and head to be the screw of tapering shape in the through hole, have under the through hole of top one with saw blade roughly with wide groove, there is an elongated hole that can supply saw blade to walk side and another side junction in the forearm bottom, with its place ahead in the same way the slightly inflexed crimp of one head is arranged, it is one corresponding with elongated hole and slightly be wider than the seam of saw blade that a upper lateral part of crimp has.
Such scheme is to change in packing into after changeing 270 ° behind the preceding curved boom, postbrachium of existing hacksaw frame and make locator roughly horizontal in the outer ring the locator on arm top, front and back is outer respectively, preceding curved boom, postbrachium on forearm, postbrachium and the hacksaw frame are kept in the same way, hang up the wing nut that saw blade tightens on the active chuck and just can carry out wide material sawing, or the shape that sawing goes out to need in the middle of material, height is adjustable as required for fore-and-aft distance during sawing.When need use breaking saw blade, as long as the interior top of elongated hole of inserting forearm that will fracture places below in the elongated hole up with a small pieces saw blade sawtooth, tighten the nut in the through hole, make the tapering screw tightly block saw blade, just can achieve the above object equally by the preceding method operation again.When running into narrow place, then the saw blade that fractures can be placed in the forearm groove during " dead band " position of some facility, the below of tapering screw, fastening nut is held the arm body and just can be carried out sawing.
The utility model has the advantages that: make existing hacksaw frame can implement wide material sawing, and can go out needed shape, and whole breaking saw blade can both use in material centre sawing, can also be at some special occasions, as narrow place, " dead band " position operation of facility.The utility model uses flexible, practical, has improved operating efficiency.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is an embodiment schematic diagram of the present utility model.
Fig. 2 is vertical view of the present utility model (screw-nut has moved to lower through-hole)
Fig. 3 is the right view of Fig. 2.
Fig. 4 is another embodiment schematic diagram of the present utility model.
Fig. 5 is another embodiment schematic diagram of the present utility model.
With reference to accompanying drawing: the multi-functional telescopic arm of hacksaw frame is made the forearm that the cross section is a Contraband shape (1) postbrachium (2) by sheet iron and is formed, and an outer ring (3) is arranged on top separately, is provided with in the outer ring to be made by sheet iron
Shape locator (4), the bottom is provided with square hole (6), locator (4) is connected with outer ring (3) by circle (5) and can does 270 ° of rotations, respectively there are a through hole (7) and (8) in one side top and the bottom of forearm, there are a nut (9) and head to be the screw (10) of tapering shape in the through hole, the visual working condition of nut and screw moves on in through hole (7) or (8), have under the through hole (7) one with saw blade roughly with wide groove (11), there is an elongated hole (12) that can supply saw blade to walk side and another side junction in the forearm bottom, with its place ahead in the same way the slightly inflexed crimp of one head (13) is arranged, it is one corresponding with elongated hole and slightly be wider than the seam (14) of saw blade that a upper lateral part of crimp has.
The utility model is after 270 ° in the work of the locator (4) on forearm (1) postbrachium (2) is turned to outside, outer ring (3) the front and back arm to be inserted preceding curved boom (15) postbrachium (16) that has hacksaw frame now respectively when using, locator (4) turns in the outer ring roughly horizontal then, preceding curved boom (15), postbrachium (16) on forearm (1) postbrachium (2) and the saw frame are kept in the same way, regulate and load onto the wing nut (17) that saw blade tightens on the active chuck (18) behind the height and can use.As long as top in the elongated hole (12) of an insertion forearm that when need use breaking saw blade, will fracture, one small pieces saw blade sawtooth is placed in the elongated hole below up and insert in the seam (14) of crimp (13) one sides, tapering screw this moment (10) is in through hole (8), follow fastening nut (9), make tapering screw (10) tightly block saw blade, can use by the preceding method operation again.When running into narrow place, during " dead band " position of some facility, tapering screw (10) nut (9) moved install in the through hole (7), again the saw blade that fractures is placed the below of groove (11) the internal taper screw (10) of forearm (1), fastening nut (9), make tapering screw (10) tightly block saw blade, hold the arm body and just can carry out sawing.
