Description
Technical field
The invention belongs to the technical field of clamping device.
Background technology
Jaw is widely used in clamping and the transfer of workpiece, and jaw comprises for the bare terminal end of holding workpiece and the drive end for exerting a force, and the bare terminal end of jaw needs the workpiece clamping different size and type usually, but existing jaw does not possess the function of measurement.
When the workpiece clamped in a period of time is not the workpiece of same size and type, whether corresponding patrolman is correct with the workpiece self checking clamping by naked eyes, and does not have corresponding scale foundation, easily causes erroneous judgement.
Summary of the invention
The invention provides a kind of jaw with measurement function, during to solve existing clamping clamping different workpieces, do not have graduated foundation, easily cause the problem of erroneous judgement.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of jaw with measurement function, comprise support body, chuck, control lever and the force application rod be slidably connected on support body, the quantity of chuck is two, also comprise the measurement rope being provided with scale layer, control lever comprise two mobile jibs and binary link, the both sides of force application rod are provided with tooth bar, the drive end of mobile jib is hinged on support body, the drive end of mobile jib is provided with the gear teeth be meshed with tooth bar, the force side of mobile jib is connected with chuck, one end and the support body of secondary bar are hinged, the other end and chuck hinged, two chucks are equipped with pole, the upper end of pole is provided with installing hole, be slidably connected in the installing hole of a pole, the one end measuring rope is fixedly connected on another pole through installing hole.
Herein, the inner side of jaw refers to the side of jaw for clamping work pieces, and the outside of jaw refers to the side outside inside jaw.
Principle of the present invention is: promote force application rod, tooth bar on force application rod can with the gear teeth meshing of mobile jib drive end, mobile jib bare terminal end is driven to open and clamp, secondary bar is also connected on chuck simultaneously, although secondary bar is a passive constraint, also ensure that the stability connected between chuck and force application rod.Pole inside jaw bare terminal end can contact with surface of the work, and the other end of pole is provided with measures rope, measures rope and is provided with scale, reads workpiece by the length clamped between two ends by the scale measured on rope.
Compared with prior art, the invention has the advantages that: 1, chuck is also provided with secondary bar except being connected with mobile jib, relative to only having a bar to connect, enhancing the stability connected between chuck and force application rod.2, measurement mechanism is provided with, workpiece is read by the length clamped between two ends by the scale measured on rope, when the workpiece clamped in a period of time is not the workpiece of same size and type, corresponding patrolman is evidence-based, instead of subjective judgement, be not easy to cause erroneous judgement to the correctness of holding workpiece.
Further, described two chucks have through hole, one end of through hole is positioned at the inner side of chuck, and the lower end of pole is positioned at the inner side of chuck through through hole, be provided with extension spring, the surface of two poles and workpiece offseted, ensure that the accuracy of measurement between two poles.
Further, the lower end of described pole is provided with catch, and the area of catch is greater than the sectional area of through hole, prevents one end of pole from dropping out from through hole.
Further, also comprise wind spring, the other end measuring rope is connected on wind spring, measure rope and be wrapped on wind spring, and wind spring is Compress Spring, thus ensures that measuring rope is in tensioned state.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the structural representation that the present invention has the jaw embodiment of measurement function.
Detailed description of the invention
Reference numeral in Figure of description comprises: support body 1, chuck 2, measurement rope 3, force application rod 4, mobile jib 5, secondary bar 6, pole 7, catch 8, not exclusively tooth 9, wind spring 10.
As shown in Figure 1, a kind of jaw with measurement function in the present embodiment, the force application rod 4 comprising support body 1, chuck 2, control lever, the measurement rope 3 being provided with scale layer, wind spring 10 and be slidably connected on support body 1, wherein, the quantity of chuck 2 is two.Control lever comprise two mobile jibs 5 and binary link 6, the length of mobile jib 5 and secondary bar 6 is equal, and the both sides of force application rod 4 are provided with tooth bar, the drive end of mobile jib 5 is hinged on support body 1, and the drive end of mobile jib 5 is provided with the incomplete tooth 9 be meshed with tooth bar.The force side of mobile jib 5 is connected with chuck 2, and upper end and the support body 1 of secondary bar 6 are hinged, lower end and chuck 2 hinged, the corresponding chuck 2 of the secondary bars 6 of mobile jib 5 one.Two chucks 2 are equipped with between pole 7, two pole 7 and are provided with extension spring, the upper end of pole 7 is provided with installing hole, is slidably connected in the installing hole of a pole 7.The left end measuring rope 3 is fixedly connected on another pole 7 through installing hole, and the right-hand member measuring rope 3 is connected on wind spring 10, measure rope 3 and be wrapped on wind spring 10, and wind spring 10 is Compress Spring, thus ensures that measuring rope 3 is in tensioned state.Two chucks 2 all have through hole, and one end of through hole is positioned at the inner side of chuck 2, and the lower end of pole 7 is positioned at the inner side of chuck 2 through through hole.The lower end of pole 7 is provided with catch 8, and the area of catch 8 is greater than the sectional area of through hole, prevents one end of pole 7 from dropping out from through hole.
Downward promotion force application rod 4, mobile jib 5 can outwards open gradually, and secondary bar 6 also can outwards move.Mobile jib 5 and secondary bar 6 form a parallelogram, make the connection between control lever and chuck 2 more stable.When chuck 2 moves on the side of workpiece time corresponding with workpiece by the position of two chucks 2, more upwards pull force application rod 4, mobile jib 5 and secondary bar 6 can make chuck 2 be in the state of gathering, thus by Workpiece clamping.
After workpiece is clamped, pole 7 can offset with the clamping face of workpiece, and pole 7 is provided with measures rope 3, measures rope 3 under the effect of coil compression springs 10, is in exceptionally straight state, and measurement rope 3 is provided with scale, read workpiece by the length clamped between two ends by the scale measured on rope 3.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
