Abstract
The invention discloses a tool clamp. The tool clamp comprises a main shaft and a pull rod, wherein a fixing sleeve is arranged on the outer side of one end of the main shaft; the inner side of the end, far away from the main shaft, of the fixing sleeve, is provided with a tapered pressing plate in a connection way; and the pull rod penetrates through the main shaft, the fixing sleeve and the tapered pressing plate, and a limit structure is respectively arranged between the pull rod and the fixing sleeve as well as between the pull rod and the tampered press plate in a matching way. The tool clamp is provided with the main shaft, the fixing sleeve and the tapered pressing plate, and the pull rod penetrates through the inner side of the tool clamp and acts to compress the tapered pressing plate, so that a workpiece is compressed, and the workpiece is convenient to clamp.
Description
Technical field
The present invention relates to a kind of frock, be specifically related to the frock clamp that a kind of lathe uses.
Background technology
Frock, established technology is equipped, and refers to the assembly of employed various tool in the manufacture process, and it comprises cutter, anchor clamps, mould, measurer, cubing, working position apparatus or the like.
Anchor clamps are to add to be used for rapid fastening workpiece man-hour, make lathe, cutter, instrument keep the process unit of correct relative position, that is to say that frock clamp is the indispensable parts of machining.Anchor clamps are claimed jig again; In a broad sense, any operation in technical process is used for rapidly, the device of convenient, safe installation workpiece; Can be called anchor clamps; For example weld jig, inspection jig, assembling jig, jig etc. are wherein especially common with jig, often abbreviate anchor clamps as.
On lathe during processing work, for the surface that makes workpiece can reach the drawing regulation size, geometry and with other surperficial specification requirement such as mutual alignment precision, must workpiece be installed (location) before the processing, clip (clamping).Yet in the prior art, all be that a frock clamp cooperates a part, frock clamp needs the machining center manufacturing, and cost is bigger, and the problem that workpiece is difficult to clamping occurs through regular meeting.
Summary of the invention
The object of the invention provides a kind of frock clamp of clamping workpiece easily.
Technical scheme of the present invention is: a kind of frock clamp; Comprise a main shaft; The said main shaft one end outside is provided with fixed cover, and said fixed cover is connected with the tapering pressing plate away from an end inboard of said main shaft, also comprises a pull bar; Said pull bar runs through said main shaft, fixed cover and tapering pressing plate, cooperates respectively between said pull bar and said fixed cover and tapering pressing plate to be provided with position limiting structure.
Further technical scheme, said pull bar is inboard to be respectively equipped with boss with said fixed cover and tapering pressing plate contact position, and it is spacing to conflict between said boss and said fixed cover and tapering pressing plate, constitutes described position limiting structure.
Further technical scheme, said fixed cover inboard is provided with locating slot.
Further technical scheme, sliding connection between said tapering pressing plate and said fixed cover inboard.
In the technique scheme, this frock clamp is made up of main shaft, fixed cover, tapering pressing plate, runs through in said main shaft, fixed cover and the tapering pressing plate being provided with pull bar; One end of pull bar connects the motor of lathe, during clamping workpiece, puts into fixed cover to workpiece earlier and locatees; Put the tapering pressing plate through the method for rotation tapering pressing plate then, make workpiece be placed between fixed cover and the tapering pressing plate, lathe drives backward stick action then; Backward stick action and then compress the tapering pressing plate through position limiting structure; Thereby force tapering pressing plate workpiece pressing, workpiece is fixed, accomplish the clamping workpiece state.
Advantage of the present invention is:
1. the present invention is through being provided with main shaft, fixed cover and tapering pressing plate; Side runs through pull bar is set within it, and pull bar one end connects the motor of lathe, and the other end cooperates with the tapering pressing plate through position limiting structure; The machine motor action drives pull bar and rotates; Pull bar and then compress the tapering pressing plate through position limiting structure, thus compress the workpiece that is positioned between fixed cover and tapering pressing plate, thus can accomplish the clamping of workpiece easily.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is a clamp view in the embodiment of the invention one;
Fig. 2 is an anchor clamps releasing orientation sketch map in the embodiment of the invention one;
Fig. 3 is the front schematic view of workpiece in the embodiment of the invention one.
Wherein: 1, main shaft; 2, fixed cover; 3, tapering pressing plate; 4, pull bar; 5, boss; 6, workpiece; 7, highlight.
The specific embodiment
Embodiment one: referring to shown in Fig. 1 to 3, a kind of frock clamp comprises a main shaft 1; The said main shaft 1 one ends outside is provided with fixed cover 2; Said fixed cover 2 is connected with tapering pressing plate 3 away from an end inboard of said main shaft 1, also comprises a pull bar 4, and said pull bar 4 runs through said main shaft 1, fixed cover 2 and tapering pressing plate 3; Said pull bar 4 cooperates respectively with said fixed cover 2 and 3 of tapering pressing plates and is provided with position limiting structure; Said pull bar 4 inboards are respectively equipped with boss 5 with said fixed cover 2 and tapering pressing plate 3 contact positions, and it is spacing to conflict between said boss 5 and said fixed cover and tapering pressing plate, constitutes described position limiting structure; Said fixed cover inboard is provided with locating slot, sliding connection between said tapering pressing plate and said fixed cover inboard.
During clamping workpiece, the fixed cover of manually putting into anchor clamps to workpiece 6 is located, and is placed in the inboard corresponding locating slot of fixed cover through three highlights 7 in the workpiece outside; Workpiece just can not rotate in anchor clamps like this; The reverse side of workpiece is a machined surface, puts the tapering pressing plate through the method for rotation tapering pressing plate then, then the driven by motor backward stick action of lathe; Position limiting structure conflict tapering pressing plate and then compress tapering pressing plate when pull bar drives; Thereby force tapering pressing plate workpiece pressing, workpiece is fixed, finally accomplish the clamping workpiece operation; Dismounting is during workpiece, and after the power of machine motor was cancelled, pull bar was no longer stressed, manually rotates the tapering pressing plate it is unclamped, and took out processing work again, finally disassembly status proportionately.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
