Abstract
The utility model relates to a drill machine cam type fastener, which is composed of a spring chuck, a cam and a cam shaft. One end of the spring chuck is provided with a chuck hole connected with an opening, and the opening end is provided with a bolt hole which has movable fit with a bolt; a bolt head of the bolt is provided with a pin shaft hole which has a movable fit with the cam shaft, and the cam is fixedly connected with the cam shaft by the bolt and nuts. The can is fixedly connected with a handle, and the distance D from the cam top to the center of the cam shaft is more than the distance d from the center of the cam shaft to the spring chuck. The utility model has the advantages of simple structure, easy and quick operation, difficult looseness after locked operation and safe work.
Description
The utility model relates to a kind of rig cammingly locking device.
At present, connect the general screw thread that adopts between the relevant parts of rig and parts, it is loaded down with trivial details not only to operate, and vibration makes its nut loosening cause the generation of mechanical disorder when also starting because of rig, not only influence working efficiency, and can damage machinery equipment even human injury takes place.
Its purpose of the utility model is: a kind of rig cammingly locking device is provided, and it is simple in structure, and is easy to use, quick, and the locking back is difficult for loosening, safe and reliable.
The utility model is achieved in that
A kind of rig cammingly locking device is made of spring collet, cam, camshaft, it is characterized in that: its spring collet is that an end is established collet bore and linked to each other with opening, and its opening end is established bolt hole and bolt movingly; The bolt head of its bolt is established pin shaft hole and camshaft movingly, and cam and camshaft are fixedly connected, and connects by bolt, nut, and cam and handle are fixedly connected, cam point to the distance D at camshaft center greater than the camshaft center arrive spring collet apart from d.
Its cam and camshaft are that key connecting, six sides, square shaft are mated axis hole, scyewed joint, welding; The head of its bolt is square body, five, the hexahedron of mesopore.
The collet bore of its spring collet be spherical, three, four, five, hexagonal prism shape, oval ball shape, the sectional shape of its opening end be rectangular, rectangular with middlely squarely combine shape, rectangular is that six sides, all directions shape combine shape with the centre.
The utility model rig cammingly locking device structure is simple, easy to use, quick, and is difficult loosening with the parts in addition of this locking device locking, thereby guarantees safe and reliable.
Further elaborate below in conjunction with embodiment and accompanying drawing:
Fig. 1: the utility model structural representation;
Fig. 2: the utility model B-B structural representation;
Fig. 3: the utility model A is to structural representation.
The utility model rig cammingly locking device, its structure is as shown in Figure 1: a kind of rig cammingly locking device, constitute by spring collet 1, cam 2, camshaft 3, it is characterized in that: its spring collet 1 is that an end is established collet bore 11 and linked to each other with opening, and its opening end is established bolt hole and bolt 5 movingly; The bolt head of its bolt 5 is established pin shaft hole and camshaft 3 movingly, cam 2 is fixedly connected with camshaft 3, and connect by bolt 5, nut 4, cam 2 is fixedly connected with handle 6, cam 2 tops to the distance D at camshaft center greater than the camshaft center to spring collet 1 apart from d.
Axis hole, scyewed joint and welding that described cam 2 and camshaft 3 adopt keys, spline, square shaft, six square shafts to be mated.
The side of pin-and-hole, five, hexahedron in the middle of the head of described bolt 5 adopts, itself and spring collet 1 junction plane are the plane.
That the collet bore 11 of described spring collet 1 adopts is spherical, three, four, five, hexagonal prism shape, oval ball shape, the sectional shape of its opening end be rectangular, rectangular with middlely squarely combine shape, rectangular is that six sides, all directions shape combine shape with the centre.
Use condition: put into spring collet 1 as long as handle 6 has upwards been removed the workpiece that will lock, handle 6 is removed downwards, at this moment, the plush copper of cam is withstood spring collet and clamping work pieces.
