Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As Figure 1-4, the utility model embodiment provides a kind of manual, it comprises clamp body 11 and clamp system, this clamp system comprises the pressing plate 12 be rotationally connected with on clamp body 11, pressing plate 12 is run through in one end and the connecting rod 13 be connected with clamp body 11 and threaded engagement in the threaded fastener 14 of the other end of connecting rod 13.Particularly, clamp body 11 can arrange connecting hole, pressing plate 12 directly matched in clearance in this connecting hole, to realize both being rotationally connected.Connecting rod 13 can be directly fixed on clamp body, and concrete fixed form can adopt interference fit, welding etc.Threaded fastener 14 is nut preferably.
Pressing plate 12 has the stroke moved axially along connecting rod 13 under the effect of threaded fastener 14, namely, when turning threaded fastener 14, threaded fastener 14 moves relative to connecting rod 13, and then band dynamic pressure plate 12 moving axially along connecting rod 13, this moving process can make pressing plate 12 gradually near workpiece.At one end place of the rotational travel of pressing plate 12, pressing plate 12 is positioned at outside parts dismounting track, that is, in this position, and the interference of the dismounting of workpiece not compression plate 12; At the other end place of the rotational travel of pressing plate 12, pressing plate 12 crimps with parts, and in this position, pressing plate 12 applies pressure, in case problems such as workpiece is collected together, shakes to workpiece.
Need by trade union college to manual time, first unscrew locking member 14, then pressing plate 12 is rotated, make pressing plate 12 dodge workpiece, then by Workpiece fixing on manual, then rotate backward pressing plate 12, when pressing plate 12 arrives the top at clamping position of workpiece, threaded together locking member 14, makes pressing plate 12 be pressed on workpiece, namely completes the clamping of workpiece.After completion of processing, only need the locking member 14 that unscrews, and rotate pressing plate 12 and can take out workpiece.
Known by foregoing description, the manual that the utility model embodiment provides, when installing workpiece and taking out workpiece, only needs to turn threaded fastener 14 and rotates pressing plate 12, need not frequent dismounting pressing plate 12, shorten the process time of workpiece with this, improve the working (machining) efficiency of parts.In addition, once the installing space of manual is limited, just can rotate pressing plate 12, make pressing plate 12 be pressed in other positions of workpiece, to adapt to the change of installing space, therefore, the operation ratio of this manual is easier to, and also can improve the working (machining) efficiency of parts.
In a kind of embodiment, above-mentioned clamp system also comprises the holder 15 be fixed on clamp body 11, and this holder 15 has installing hole, and pressing plate 12 is rotationally connected with in this installing hole, and connecting rod 13 is connected with clamp body 11 by holder 15.Compared to the direct mode be rotationally connected with by pressing plate 12 on clamp body 11, above-mentioned holder 15 is larger with the contact area of pressing plate 12 and connecting rod 13, and stability when pressing plate 12 is rotated is higher.
When pressing plate 12 rotates relative to holder 15, the problem that wear extent that is that cause is excessive in order to prevent the rotation amplitude of pressing plate 12 excessive, also on the top of holder, limiting section 151 can be set away from the side in position components space, this limiting section 151 have the arc guide surface fitted with the lateral surface of pressing plate 12 and keep off with pressing plate 12 phase the rotary spacing face connect.Whole limiting section 151 can curved structure, and this arcuate structure has breach, and this breach is for holding the rotating part of pressing plate 12.The rotation that arc guide surface is pressing plate 12 provides additional guiding, and rotary spacing face is then for limiting the rotation amplitude of pressing plate 12.Particularly, rotary spacing face can adopt plane, and the opposite end of arc guide surface all can arrange rotary spacing face.
Rotate in the process of pressing plate 12, due to the Action of Gravity Field of pressing plate 12 self, after making pressing plate 12 and absorption surface, will there is larger frictional force between the two, this frictional force easily produces workpiece and scratches.For this reason, the clamp system that the utility model embodiment provides also comprises the elastic component 16 being set in connecting rod 13 outside, and the two ends of this elastic component 16 are connected between pressing plate 12 and holder 15 respectively.This elastic component 16 is chosen as spring, it can apply active force to pressing plate 12, makes pressing plate 12 be in position away from workpiece, when pressing plate 12 turns to the top at clamping position of workpiece, drive pressing plate 12 gradually near workpiece by threaded fastener 14, till pressing plate 12 with absorption surface.Obviously, this kind of structure makes to there is Relative friction hardly between pressing plate 12 and workpiece, then protects workpiece.
In previous embodiment, the part that pressing plate 12 is rotatably assorted with holder 15 is columnar part, this columnar part can be offered the accommodating endoporus of elastic component, and one end of elastic component 16 is connected on the shoulder hole wall of the accommodating endoporus of elastic component.The endoporus of holder 15 can be set to shoulder hole, the part that on this shoulder hole, aperture is less is only passed for connecting rod 13, the larger part in aperture was then both passed for connecting rod 13, and also for installing elastic component 16, the two-part joint of this shoulder hole forms the shoulder hole wall of the accommodating endoporus of elastic component.After adopting this kind of structure, pressing plate 12 be absorbed in the degree of depth in holder 15 larger time, elastic component 16 still has enough length, and therefore this structure both can ensure the elastic force that elastic component 16 can provide, and the structure of manual can also be made compacter.
In another embodiment, the installing hole of holder 15 can be set to shoulder hole, and the aperture that this shoulder hole comprises the first connected hole 152 and the second hole 152, hole 153, first is greater than the aperture in the second hole 153, pressing plate 12 is rotationally connected with in the first hole 152, and connecting rod 13 is threadedly connected in the second hole 153.This is relatively simple for structure, is convenient to processing.
Holder 15 is fixed on clamp body 11 by the mode of interference fit, but for the ease of the dismounting of holder 15, can arrange adpting flange 154 on holder 15, and the bottom of holder 15 is inserted in clamp body 11, this adpting flange 154 is fixed by threaded fastener with clamp body 11.The bottom of holder 15 is inserted in clamp body 11, can ensure the positional precision of holder 15.In addition, the clamp system that the utility model embodiment provides also can comprise spheric washer 17, and this spheric washer 17 is installed between threaded fastener 14 and pressing plate 12.After adopting spheric washer 17, threaded fastener 14 is more balanced with the active force of pressing plate 12, and both are not easy to occur because of relative motion scratching in the course of the work.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
