The clamp aims at solving the technical problem of providing a clamp which can accurately position and reliably clamp workpieces having complex shapes on a lathe. The technical scheme is that: a clamp body is connected with a receiving tray through bolts; the left end surface of the clamp body is provided with three support pins through threads; the center of the receiving tray is provided with a through hole; a connecting tray is installed in the through hole at the center of the receiving tray; a draw bar is connected to the right end surface of the receiving tray through bolts; the clamp body is provided with three oblique 45-degree through holes; three sliding columns are installed in the three oblique 45-degree through holes of the clamp body respectively; the connecting tray is connected with the three sliding columns through three connecting plates; the three sliding columns are in threaded connection with one ends of three stand columns respectively; and the other ends of the three stand columns are connected with three pressing plates through bolts respectively. The clamp can clamp workpieces having complex shapes.
Description
Technical field
A kind of anchor clamps of the utility model belong to the clamp technology field, particularly relate to a kind of anchor clamps of workpiece that can the clamping complex contour.
Background technology
Device in order to clamping workpiece or guiding cutter is called anchor clamps, anchor clamps very universal in machining industry, and commonly used on the lathe have two-jaw(ed)chuck, scroll chuck and a chuck.In that being carried out turning, the support stator face of freezer compressor and crankshaft hole add man-hour, because the profile more complicated of workpiece, general normal common scroll chuck is reequiped afterwards clamping or is added special-purpose soft pawl with two-jaw(ed)chuck come clamping work pieces, this installation way location is inaccurate, it is also unreliable to clamp, and can not well guarantee processing request.
The utility model content
The utility model overcomes the deficiencies in the prior art, technical problem to be solved provide a kind of on lathe accurate work piece positioning, the positioning and reliable clamping anchor clamps to complex contour.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of anchor clamps, comprise pressing plate, column, clamp body, connect dish, traveller, terminal pad, connecting plate, a pull bar and a nail, clamp body by bolt with connect the dish be connected, the right side of clamp body is contacted with the left side that connects dish, by screw thread three nails are installed on the left side of clamp body, the described center that connects dish has through hole, terminal pad is installed in the through hole that meets disk center, pull bar is connected on the right side of described terminal pad by screw, have three oblique through holes of 45 ° on the described clamp body, three travellers are installed in respectively in three oblique 45 ° of through holes of described clamp body, described terminal pad is connected with three travellers by three connecting plates, one end of three connecting plates is all hinged with terminal pad, the other end of three connecting plates is hinged with an end of three travellers respectively, the other end of three travellers respectively with an end of three columns by being threaded, the other end of three columns is connected with three pressing plates respectively by bolt.
The beneficial effect that the utility model is compared with prior art had is:
1, power source of the present utility model is a hydraulic cylinder, makes that clamping is quick and laborsaving.
2, the utility model is simple in structure, cooperates to come clamping work pieces by nail with pressing plate, and is effective to the clamping of the workpiece of complex contour.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1 is pressing plate, and 2 is column, and 3 is clamp body, and 4 for connecing dish, and 5 is traveller, and 6 is terminal pad, and 7 is connecting plate, and 8 is pull bar, and 9 are a nail.
The specific embodiment
As Fig. 1, shown in Figure 2, a kind of anchor clamps of the utility model, comprise pressing plate 1, column 2, clamp body 3, connect dish 4, traveller 5, terminal pad 6, connecting plate 7, a pull bar 8 and a nail 9, clamp body 3 by bolt with connect dish and 4 be connected, the right side of clamp body 3 is contacted with the left side that connects dish 4, by screw thread three nails 9 are installed on the left side of clamp body 3, the described center that connects dish 4 has through hole, terminal pad 6 is installed in the through hole that connects dish 4 centers, pull bar 8 is connected on the right side of described terminal pad 6 by screw, have three oblique through holes of 45 ° on the described clamp body 3, three travellers 5 are installed in respectively in three oblique 45 ° of through holes of described clamp body 3, described terminal pad 6 is connected with three travellers 5 by three connecting plates 7, one end of three connecting plates 7 is all hinged with terminal pad 6, the other end of three connecting plates 7 is hinged with an end of three travellers 5 respectively, the other end of three travellers 5 respectively with an end of three columns 2 by being threaded, the other end of three columns 2 is connected with three pressing plates 1 respectively by bolt.
During use, the utility model is installed on the lathe spindle, and the utility model is connected with main shaft by connecing dish 4, and connecing the right side of coiling 4 central through holes is taper, the cone of spindle nose and the cone match location that connects dish 4 central through holes will connect dish 4 by bolt then and link together with main shaft.Pull bar 8 links together with the piston rod that is installed in the hydraulic cylinder on the main shaft.
Workpiece is placed between a pressing plate 1 and the nail 9, the primer fluid cylinder pressure, the piston rod of hydraulic cylinder is moved right by pull bar 8 drive terminal pads 6, terminal pad 6 by connecting plate 7 drive travellers 5 in 45 ° of inclined holes of clamp body 3 to lower slider, thereby drive column 2 and pressing plate 1 and move right clamping work pieces.After workpiece was finished processing, the piston rod of hydraulic cylinder was moved to the left by pull bar 8 drive terminal pads 6, and terminal pad 6 drives travellers 5 by connecting plate 7 and upwards slides in 45 ° of inclined holes of clamp body 3, thereby drive column 2 and pressing plate 1 are moved to the left, and unclamp workpiece.
