Abstract
The utility model relates to a clamp device, in particular to a clamp device, which is applicable to the test piece type workpiece on the clamp milling machine etc mechanical processing equipment, belonging to the clamp technical field. The clamp device including: a clamping screw rotating and supporting on a frame fixed connecting fitting ; jaw clamp, which forming a mobile accessory equipment with the frame fixed connecting fitting; nut, which is fixed on the jaw clamp, constitutes the screw accessory equipment with the clamp screw. The utility model has the improvements of that: the clamping screw is respectively provided with the two kinds of rotary directions thread, two pieces of the jaw clamp are fixed with two kinds of rotary directions nut corresponding to the clamping screw, one end of the clamping screw is connected with the rotating power source through the drive mechanism. Therefore, when the power source drive the clamping screw to rotate through the drive mechanism, the two kinds of rotary directions screw will drive corresponding nut on the two jaw clamps, under constraint of the mobile accessory equipment, two jaw clamps carry out the relative movement at the same time, which will automatically and rapidly clamp the test piece, so as to process rapidly.
Description
Technical field
The utility model relates to a kind of gripping mechanism, and especially a kind of gripping mechanism that is applicable to test specimen class workpiece on the machining equipments such as clamping milling machine belongs to the clamp technology field.
Background technology
Clamp is the work holder of using always.Existing clamp usually by be supported on clamping screw on the clamp seat, with the clamp seat forms moving sets the jaw folder, be fixed on the jaw folder and nut that clamping screw constitutes screw pair constitutes.For the machining apparatus that milling fast of multiple shape test specimen and so on smelted in processing, existing clamp can not satisfy the needs that clamp fast automatically, therefore need improve.
The utility model content
The purpose of this utility model is: at the shortcoming that above prior art exists, proposes a kind of automatic active grab device of clamping fast can realized, thereby satisfiedly mill and so on the needs that machining equipment clamps test specimen fast fast.
In order to reach above purpose, automatic active grab device of the present utility model comprise rotatable be supported on clamping screw on the frame fastening member, with the frame fastening member form moving sets the jaw folder, be fixed on the jaw folder and go up nut with clamping screw formation screw pair, its improvements are: the screw thread that is shaped on two kinds of rotation directions on the described clamping screw, described jaw accompanies two, described two jaws folder is fixed with the nut of the two kind rotation directions corresponding with clamping screw respectively, and an end of described clamping screw is connected with rotating power source by transmission mechanism.
Like this, when power source drives the clamping screw rotation by transmission mechanism, the screw thread of two kinds of rotation directions will drive the corresponding nut on the two jaws folder respectively, under the constraint of moving sets, two jaws folder is done relative motion simultaneously, thereby fast test specimen is clamped automatically, is convenient to rapid processing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Embodiment one
Present embodiment is a kind of automatic active grab device that is applied on the quick milling machine in laboratory, its structure as depicted in figs. 1 and 2, clamping screw 4 two ends by bearings on the steering stem comp 14 that frame is connected, its left and right external screw thread that is shaped on two kinds of rotation directions respectively.Simultaneously, the axis of guide 13 is housed also on the steering stem comp 14, this axis of guide 13 is by being fixed on the axle sleeve and the jaw folder formation moving sets of jaw folder 8 (about two) bottom.Left and right two jaws folder is fixedlyed connected with left and right copper nut 5,12 respectively, and two copper nuts 5,12 are shaped on respectively and the left and right two kinds of rotation direction internal threads that match of clamping screw.The right-hand member of clamping screw 4 is connected with big synchronous pulley 17, by synchronously with 18 be fixed on air motor output shaft 29 on small synchronous pulley 26 be connected.
When air motor drives the clamping screw rotation by synchronous belt drive mechanism, the screw thread of two different rotation directions will drive the corresponding nut on the two jaws folder respectively, under the constraint of the axis of guide, two jaws folder is done relative motion simultaneously, thereby fast test specimen is clamped automatically, after being convenient to quick Milling Process, in time carry out the Metallographic Analysis of test specimen, be used to instruct follow-up smelting operation.
In addition, the automatic active grab device of present embodiment also comprises the cylinder 23 that is vertically mounted on the two jaws folder lower linking plate assembly 14, be fixed with at the material bearing shelf 10 between the two jaws folders by threaded connector on this ejecting rod of cylinder, therefore can be under the drive of cylinder, the its clamped height of control test specimen further facilitates quick milling.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (4)
