Abstract
The utility model discloses a tool clamp, comprising a spindle and a pull rod. A fixing sleeve is arranged on the outer side of one end of the spindle; a tapered pressing board is connected to the inner side of one end, which is far from the spindle, of the fixing sleeve; the pull rod passes through the spindle, the fixing sleeve and the tapered pressing board; and limiting structures are respectively arranged between the pull rod and the fixing sleeve and between the pull rod and the tapered pressing board in a matching manner. The tool clamp provided by the utility model is provided with the spindle, the fixing sleeve and the tapered pressing board the inner sides of which are penetrated through by the pull rod, so that the pull rod moves to press the tapered pressing board so as to press a workpiece. Therefore, the workpiece can be conveniently clamped.
Description
Technical field
The utility model relates to a kind of frock, is 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 etc.
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, frock clamp is the indispensable parts of machining.Anchor clamps claim again jig, in a broad sense, any operation in technical process, be used for rapidly, the device of convenient, safe installation workpiece, can be called anchor clamps, such as weld jig, inspection jig, assembling jig, jig etc., wherein especially common with jig, often referred to as anchor clamps.
On lathe during processing work, for the surface energy that makes workpiece reach the drawing regulation size, geometry and with other surperficial specification requirement such as relative-position error, workpiece must 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 larger, and often the problem that workpiece is difficult to clamping can occur.
Summary of the invention
The utility model purpose provides a kind of frock clamp of easily clamping workpiece.
The technical solution of the utility model is: a kind of frock clamp, comprise a main shaft, the described main shaft one end outside is provided with fixed cover, described fixed cover is connected with the tapering pressing plate away from an end inboard of described main shaft, also comprise a pull bar, described pull bar runs through described main shaft, fixed cover and tapering pressing plate, cooperates respectively between described pull bar and described fixed cover and tapering pressing plate to be provided with position limiting structure.
Further technical scheme, described pull bar is inboard to be respectively equipped with boss with described fixed cover and tapering pressing plate contact position, conflicts between described boss and described fixed cover and tapering pressing plate spacing, consists of described position limiting structure.
Further technical scheme, described fixed cover inboard is provided with locating slot.
Further technical scheme, sliding connection between described tapering pressing plate and described fixed cover inboard.
In the technique scheme, this frock clamp is by main shaft, fixed cover, the tapering pressing plate consists of, run through described main shaft, be provided with pull bar in fixed cover and the tapering pressing plate, the motor of one end connecting machine tool of pull bar, during clamping workpiece, first workpiece being put into fixed cover locates, then by the method for rotation tapering pressing plate the tapering pressing plate is put, so that workpiece is placed between fixed cover and the tapering pressing plate, then lathe drives backward stick action, backward stick action and then compress the tapering pressing plate by position limiting structure, thus force tapering pressing plate workpiece pressing, workpiece is fixed, finished the clamping workpiece state.
The utility model has the advantages that:
1. the utility model is by arranging main shaft, fixed cover and tapering pressing plate, side runs through pull bar is set within it, the motor of pull bar one end connecting machine tool, the other end cooperates with the tapering pressing plate by position limiting structure, the machine motor action drives pull bar and rotates, pull bar and then compress the tapering pressing plate by position limiting structure, thus compress the workpiece that is positioned between fixed cover and tapering pressing plate, thus can finish easily the clamping of workpiece.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is clamp view among the utility model embodiment one;
Fig. 2 is anchor clamps releasing orientation schematic diagram among the utility model embodiment one;
Fig. 3 is the front schematic view of workpiece among the utility model embodiment 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, comprise a main shaft 1, the described main shaft 1 one ends outside is provided with fixed cover 2, described fixed cover 2 is connected with tapering pressing plate 3 away from an end inboard of described main shaft 1, also comprise a pull bar 4, described pull bar 4 runs through described main shaft 1, fixed cover 2 and tapering pressing plate 3, described pull bar 4 cooperates respectively with described fixed cover 2 and 3 of tapering pressing plates and is provided with position limiting structure, described pull bar 4 inboards are respectively equipped with boss 5 with described fixed cover 2 and tapering pressing plate 3 contact positions, conflict between described boss 5 and described fixed cover and tapering pressing plate spacing, consist of described position limiting structure, described fixed cover inboard is provided with locating slot, sliding connection between described tapering pressing plate and described fixed cover inboard.
During clamping workpiece, the fixed cover of manually workpiece 6 being put into anchor clamps is located, be placed in the inboard corresponding locating slot of fixed cover by three highlights 7 in the workpiece outside, workpiece just can not rotate in anchor clamps like this, the reverse side of workpiece is machined surface, then by the method for rotation tapering pressing plate the tapering pressing plate is put, then the driven by motor backward stick action of lathe, position limiting structure conflict tapering pressing plate and then compression tapering pressing plate when pull bar drives, thereby force tapering pressing plate workpiece pressing, workpiece is fixed, finally finished the clamping workpiece operation; Dismounting is during workpiece, and after the power of machine motor was cancelled, pull bar was no longer stressed, and manual rotation tapering pressing plate unclamps it, takes out processing work again, finally disassembly status proportionately.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
