Abstract
The utility model discloses a fast clamping device of a workpiece, comprising a fixed seat and a positioning core shaft, wherein the positioning core shaft is connected with a clamping mechanism which comprises a pressing rod; the pressing rod is internally provided with a chamber which contains a telescopic positioning column; the pressing rod is provided with a sliding groove which is internally provided with a rotary pin which can slide relatively along the sliding groove and is hinged with a pressing stud; and the pressing stud is connected with the positioning core shaft. Compared with the original structure, the device does not need a special wrench and opened washers for picking and placing, has high clamping speed, and shortens the non-cutting time, thus improving production efficiency; and as thread connection for clamping is in the workpiece and the combined length is lengthened simultaneously, the working environment is improved, therefore, the device has low fault rate and is safe and reliable.
Description
Technical field
The utility model relates to a kind of workpiece fast fixture of machining midplane and groove processing use.
Background technology
At present, in the machining on milling machine or machining center in batches during milling plane, the structure of used clamping device as shown in Figure 1, workpiece 1 is fixed on the holder 10 in conjunction with open washer 3 and nut 4 with positioning core axle 2, one end of positioning core axle 2 has screw thread, clamp with open-end wrench during installation, need clamp or unclamp nut 4, put open washer 3 with open-end wrench during each work-handling, handling speed be slow; Nut 4 junction screw threads are because of often changing the fault rate height in conjunction with the short fragile need of length simultaneously.
The utility model content
The technical problems to be solved in the utility model is the deficiency at technique scheme, and a kind of workpiece fast fixture that can load and unload fast is provided.
For solving the problems of the technologies described above the technical solution of the utility model be:
A kind of workpiece fast fixture comprises holder and positioning core axle, it is characterized in that: be connected with clamp mechanism on the described positioning core axle.
Below be to further improvement in the technical proposal:
Described clamp mechanism comprises compressor arm, has chamber in the described compressor arm, accommodate telescopic positioning post in the described chamber, have chute on the described compressor arm, being provided with in the described chute can be along the relative fulcrum post that slides of chute, described fulcrum post is hinged with and compresses double-screw bolt, and the described double-screw bolt that compresses is connected with positioning core axle.
Has spring between the bottom of described reference column and chamber.
Described positioning core axle with compress double-screw bolt and be threaded.
During clamping work pieces, after loading onto workpiece and putting in place the compressor arm revolution is made the spring compression to short end pulling compressor arm for 90 ° then, clockwise rotate compressor arm at last, lathe is started working after making the compressor arm workpiece pressing, when completion of processing need be unclamped workpiece, rotates counterclockwise compressor arm one circle earlier, spacer pin is outwards motion under spring action, drive compressor arm to long end motion, rotate compressor arm then and make its axis consistent, just can take off workpiece with positioning core axle.
Adopt the novel advantage of this reality of technique scheme to be: this device is compared with original structure, no longer needs special spanner and picks and places open washer, and clamping speed is fast, enhances productivity thereby shorten the non-cutting time; Be in the inner while of workpiece in conjunction with the length lengthening owing to clamp used being threaded, its working environment improved, thereby make at the bottom of this plant failure rate, safe and reliable.
Below in conjunction with drawings and Examples technique scheme is done further improvement:

Among the figure: the 1-workpiece; The 2-positioning core axle; The 3-open washer; The 4-nut; The 5-internal thread; 6-compresses double-screw bolt; The 7-compressor arm; The 8-fulcrum post; The 9-spring; The 10-holder; The 11-chamber; The 12-reference column; The 13-chute.
The specific embodiment
Embodiment, as shown in Figure 2, a kind of workpiece fast fixture, comprise holder 10 and positioning core axle 2, be connected with clamp mechanism on the described positioning core axle 2, described clamp mechanism comprises compressor arm 7, has chamber 11 in the described compressor arm 7, accommodate telescopic positioning post 12 in the described chamber 11, have spring 9 between the bottom of described reference column 12 and chamber 11, have chute 13 on the described compressor arm 7, being provided with in the described chute 13 can be along the chute 13 relative fulcrum post 8 that slide, reference column 12 contacts with fulcrum post 8 under the effect of spring 9, and give fulcrum post 8 pressure, described fulcrum post 8 is hinged with and compresses double-screw bolt 6, has and compress the internal thread 5 of double-screw bolt 6 cooperations in the described positioning core axle 2, the length of described internal thread 5 is longer than the length that compresses double-screw bolt 6 screw threads, and the described double-screw bolt 6 that compresses is threaded with positioning core axle 2.
As shown in Figure 3, described clamp mechanism comprises compressor arm 7, has chamber 11 in the described compressor arm 7, accommodate telescopic positioning post 12 in the described chamber 11, has spring 9 between the bottom of described reference column 12 and chamber 11, have chute 13 on the described compressor arm 7, being provided with in the described chute 13 can be along the chute 13 relative fulcrum post 8 that slide, and described fulcrum post 8 is hinged with and compresses double-screw bolt 6.
During clamping work pieces, after loading onto workpiece 1 and putting in place with 90 ° of compressor arm 7 revolutions, pulling compressor arm 7 makes spring 9 compression, clockwise rotates compressor arm 7 at last, make compressor arm 7 workpiece pressings after lathe start working, when completion of processing need be unclamped workpiece, rotate counterclockwise compressor arm 7 one circles earlier, alignment pin 12 outwards motion under spring 9 effects drives compressor arm 7 to long end motion, rotate compressor arm 7 then and make its axis consistent, just can take off workpiece with positioning core axle 2.
Adopt the novel advantage of this reality of technique scheme to be: this device is compared with original structure, no longer needs special spanner and picks and places open washer, and clamping speed is fast, enhances productivity thereby shorten the non-cutting time; Be in inside workpiece simultaneously in conjunction with the length lengthening owing to clamp used being threaded, its working environment improved, thereby make at the bottom of this plant failure rate, safe and reliable.
