Abstract
The utility model discloses a machine tool component, and particularly relates to a connecting rod clamping mechanism. The connecting rod clamping mechanism comprises a movable connecting rod and clamping jaws, wherein the movable connecting rod is movably connected with a fixture body and can only move in the horizontal direction, the number of the clamping jaws is two, one end of each clamping jaw is used for clamping a workpiece, the other end of the corresponding clamping jaw is fixedly connected with one end of the movable connecting rod, and the other end of the movable connecting rod is movably connected with a pull rod arranged vertically through a connecting rod. The connecting rod clamping mechanism is convenient and fast to operate, low in using cost and simple in structure.
Description
Technical field
The utility model relates to a kind of machine tool component, is specifically related to a kind of link-type clamping mechanism.
Background technology
In mechanical processing process, usually need first workpiece to be fixed by clamp mechanism, make workpiece obtain the tram with respect to lathe and cutter, then workpiece is processed.By clamp mechanism, workpiece is fixed, because the positional precision of workpiece is guaranteed by clamp mechanism, can not be subject to the impact of workman's technical merit, so Workpiece Machining Accuracy is high and stable, and then the rate of reducing the number of rejects and seconds, guaranteed the quality of product; Because clamp mechanism can make workpiece location and clamping rapidly, reduce significantly unproductive time again, improved production efficiency.So both can guarantee mechanical processing quality, and enhance productivity, reduce labor intensity, can reduce again the excessive demand to workman's technology.
But some clamp mechanism complex structure, complex operation and maintenance nursing are very expensive, and use cost is high, is not suitable for midget plant and uses.
Utility model content
The defect existing for above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of convenient to operation, link-type clamping mechanism that use cost is cheap and simple in structure.
In order to solve the problems of the technologies described above, the utility model provides a kind of link-type clamping mechanism, comprises movable rod and jaw, and described movable rod is flexibly connected with clamp body and can only moves by along continuous straight runs; Described jaw has two, and jaw one end is for holding workpiece, and the other end is fixedly connected with movable rod one end, and the movable rod other end is flexibly connected with the pull bar vertically arranging by connecting rod.
The link-type clamping mechanism that adopts said structure, due in the time that connecting rod pumps, by connecting rod, can drive movable rod to do reciprocal horizontal movement, and then drives jaw to do reciprocal horizontal movement, so just can make jaw workpiece be clamped or unclamp.Adopt after such structure, only just can realize the clamping to workpiece by control link, simple to operate, and simple in structure, easily, use cost is cheap in maintenance nursing.
One as the above-mentioned link-type clamping mechanism of the utility model is improved: described movable rod is U-shaped structure.Because movable rod is U-shaped structure, in the time that jaw is excessive to the clamping force of workpiece, U-shaped movable rod can produce strain, and then reduces the suffered clamping force of workpiece.
As the further improvement to link-type clamping mechanism preferred version, between described jaw and movable rod, be fixedly connected with by adjustable hold-down bolt.Due to by the adjustable hold-down bolt of rotation, can regulate the distance between jaw and movable rod, can make jaw be applicable to the workpiece of different sizes.
As the further improvement to link-type clamping mechanism preferred version, described jaw is provided with cushion for one end of holding workpiece.Adopt after such structure, can prevent that surface of the work from being scratched by jaw.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model link-type clamping mechanism embodiment.
the specific embodiment
In figure, 1 is jaw, and 2 is movable rod, and 3 is connecting rod, and 4 is pull bar, and 5 is adjustable hold-down bolt, and 6 is cushion.
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further detail:
As shown in Figure 1, comprise movable rod 2 and jaw 1, described movable rod 2 is U-shaped structure, and movable rod 2 is flexibly connected and can only moves by along continuous straight runs with clamp body (not shown); Described jaw 1 has two, and jaw 1 one end is used for holding workpiece and is provided with elasticity 6 padding, and the other end is fixedly connected with by screw thread with movable rod 2 one end by adjustable hold-down bolt 5, and movable rod 2 other ends are hinged with the pull bar 4 vertically arranging by connecting rod 3.On clamp body, be also provided with infrared alignment device.
When use, can drive pull bar to pump by cam mechanism.In the time that connecting rod is positioned at level, between two jaws, distance farthest, is positioned over workpiece to be processed between two jaws, by infrared alignment device, the location of workpiece is finely tuned, and workpiece level is placed.In the time that connecting rod tilts, jaw, by Workpiece clamping, just can be processed workpiece.After workpiece completion of processing, drive pull bar by controlling cam mechanism, make two jaws away from, the workpiece of having processed is taken out and puts into next one workpiece to be processed.
In the time that jaw is excessive to the clamping force of workpiece, U-shaped movable rod can produce strain, and then reduces the suffered clamping force of workpiece, prevents that workpiece is impaired.
Pull bar also can drive by devices such as cylinder or hydraulic jacks.
Below by reference to the accompanying drawings to described be only preferred embodiment of the present utility model; but the utility model is not limited to above-mentioned embodiment; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make various distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
