Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
as shown in accompanying drawing 1 to Fig. 8, of the present inventionly disclose a kind of saw blade clamping apparatus and be removably connected with reciprocating lever 3 for the saw blade 1 that cut workpiece is used.Cut workpiece can be the similar machining tools such as sweep-saw and reciprocating saw.
as the saw blade 1 in accompanying drawing the present invention has the inclined-plane 11 forming in the end of its direction of insertion and the end face 12 seamlessly transitting with this inclined-plane 11.Inclined-plane 11 can be that arcwall face can be also plane, and end face 12 is generally plane.Between inclined-plane 11 and end face 12, do not exist dead angle stuck in its motion process to prevent locating shaft 7.
a kind of saw blade clamping apparatus disclosed by the invention, it comprises clamper main body 2, clamping element 4 and clamp mechanism.
as Figure 1-3, one end of clamper main body 2 and reciprocating lever 3 are fixedly connected, and this kind of connection can be passed through the various fixed forms such as bolt, screw and realize.On the other end of clamper main body 2, offer accepting groove (not marking in figure), saw blade 1 can insert realization clamping in this accepting groove and fix.Offer a groove 5 at the middle part of clamper main body 2, the length direction of this groove 5 parallels with the direction of insertion of saw blade 1.
the restriction end of clamping element 4 is connected with clamper main body 2, and the free end of clamping element 4 can offset with the insertion end of saw blade, and in the process of inserting at saw blade, this clamping element 4 is compressed.Concrete, in the present embodiment, clamping element 4 is spring, the flexible direction of this spring parallels to exit in process and more smoothly saw blade is ejected at saw blade with the direction of insertion of saw blade.
as Figure 4-8, clamp mechanism comprises the briquetting 6 that is rotatably arranged on clamper main body 2, is plugged in locating shaft 7 in described groove 5, is arranged on reposition element 8 and locking device between locating shaft 7 and clamper main body 2.
locating shaft 7 is plugged in groove 5, and the diameter of axle of locating shaft 7 is less than the height of groove 5, and it can length direction and the short transverse along groove 5 move in this groove 5.
briquetting 6 is rotated and is arranged on clamper main body 2 by a rotating shaft, and briquetting 6 has one and inserts at saw blade 1 contact-making surface 61 that the distance of accepting groove to the process of clamped position and between the sidepiece of saw blade 1 diminishes gradually.This contact-making surface 61 can be inclined-plane or curved surface.This contact-making surface uprises gradually from saw blade 1 direction of insertion.
in saw blade insertion process, locking device limits the active force that briquetting rotates, and gives the active force of the relative saw blade motion of locating shaft by briquetting.
in the present embodiment, locking device comprise one be rotatably arranged on the latch segment 9 on clamper main body 2 and be arranged on latch segment 9 and clamper main body 2 between elastic component 10.This elastic component 10 can be after locking device and briquetting 6 releases, and saw blade 1 resets to latch segment 9 after exiting accepting groove.Latch segment 9 has flex point (in figure do not mark), second curved surface 92 of first surface 91 and between first surface 91 and the second curved surface 92, when the first surface 91 of described latch segment 9 contacts with briquetting 6, described locking device is locked mutually with described briquetting 6, when described latch segment 9 rotates through after flex point, described locking device and described briquetting 6 phase releases, described the second curved surface 92 is spacing for giving described briquetting 6 at described locking device during with described briquetting 6 phase release.Elastic component 10 can have for torsion spring or other element of reset function.
certainly, the locking device in the present invention should only not be confined to this, all should be included in the protection domain of this invention as long as realize the locking of briquetting action and any mechanism of release and device.
operation principle of the present invention is as follows:
as shown in Figure 4, saw blade clamping apparatus in the present invention is in the time of free state, in the process of insertion saw blade 1, as shown in the dotted portion of Fig. 7 and solid line part, described locating shaft 7 is by the slope driving of saw blade, because locating shaft 7 also contacts with the contact-making surface of briquetting 6, the relative saw blade of locating shaft 7 is the direction of insertion motion of saw blade dorsad, be that locating shaft 7 moves up along the inclined-plane of saw blade, until locating shaft 7 moves to the end face of saw blade, now, under the promotion of reposition element 8, the rightabout that locating shaft 7 inserts towards saw blade 1 moves and is locked between the inclined-plane of saw blade and the contact-making surface of briquetting, finally saw blade is realized locking as shown in Figure 6.
as shown in Figure 6, saw blade of the present invention is clamped by saw blade clamping apparatus, as shown in the solid line part of accompanying drawing 8 and dotted portion, in the process of unloading saw blade 1, rotation lock piece 9, in the time that contacting with briquetting 6, realizes on the second curved surface 92 of latch segment 9 release of briquetting 6, reposition element 8 provides the reset force of saw blade 1 direction of insertion motion dorsad to described locating shaft 7, and order about described locating shaft 7 and do not produce active force with the contact-making surface 61 of described briquetting 6, now clamping element 4 provides the reset force of saw blade 1 direction of insertion motion dorsad to saw blade 1, orders about saw blade 1 and exits accepting groove.
above specific embodiment of the present invention is illustrated in conjunction with diagram, not leaving on the basis of scope and spirit of the present invention clearly, can much revise prior art and technique.Under of the present invention, in technical field, the common knowledge of a GPRS, just can, within the scope of technology main idea of the present invention, carry out diversified change.
