Abstract
The invention belongs to a fixture, and in particular relates to a machining fixture of a free compression element for an industrial sewing machine. The machining fixture is characterized by comprising a bottom plate, a vertical plate and quick card mounting mechanisms, wherein each quick card mounting mechanism is arranged on the upper part of the vertical plate and comprises an upper movable pressure foot, a lower movable pressure foot and an eccentric compression mechanism; square grooves which are connected with the upper movable pressure feet and the lower movable pressure feet in a sliding mode are formed on the vertical plate; workpiece positioning pins which correspond to the space between the upper movable pressure feet and the lower movable pressure feet are arranged on the vertical plate; pressure claws perpendicular to bodies of the pressure feet are arranged at the front ends of the upper movable pressure feet and the lower movable pressure feet; and the rear ends of the upper movable pressure feet and the lower movable pressure feet are in pin joint with the eccentric compression mechanisms through pin shafts. Compared with the conventional standard part fastening tool, the machining fixture has the advantages that the machining fixture is convenient and quick, is high in production efficiency and has uniform and reliable pressing force; due to the adjustment of limiting screws, the uniformity of clamping force can be ensured; and the efficiency of the machining fixture is 50 to 60 percent higher than that of a fixture which is not improved.
Description
Technical field
The invention belongs to anchor clamps, relate in particular to the machining fixture that a kind of industrial sewing machine is freely pressed unit.
Background technology
Industrial sewing machine freely give as security first working position: mill upper and lower movable presser feet and the movable presser feet groove 6.4+0.027/0 down of, bore, hinge
2 holes.This workpiece of tradition processing is through bolt and pressing plate workpiece to be fixed; Detect whether level of workpiece with lever meter then; Just need readjust fastening when out-of-level; And then measure till level, all need adjust and just can meet the requirements for several times though this method can reach each part of requirement, interchangeability is very poor after the very low and workpiece processing of efficient.Could accomplish several times so repeatedly, efficiency is extremely low, can not adapt to requirements of large-scale production at all.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, provide a kind of convenient and swift, production efficiency is high, the balanced industrial sewing machine reliably of thrust freely is pressed first machining fixture.
The present invention is for realizing above-mentioned purpose; Realize through following technical scheme; A kind of industrial sewing machine is freely pressed the machining fixture of unit; It is characterized in that: comprise base plate, riser and rapid-mounted mechanism, said riser is connected with the base plate vertical fixing, and said riser top is provided with rapid-mounted mechanism; Said rapid-mounted mechanism comprises two parallel last movable presser feets and movable presser feet, eccentric hold-down mechanism down; Said riser is provided with the square groove that is slidingly connected with last movable presser feet and following movable presser feet, and corresponding going up between movable presser feet and the following movable presser feet is provided with the workpiece alignment pin on the said riser, and said movable presser feet is provided with the paw vertical with its body with following movable presser feet front end; Said movable presser feet is with movable presser feet rear end is through bearing pin and eccentric hold-down mechanism pin joint down, and the said movable presser feet and the corresponding location of workpiece of down movable presser feet front end are provided with fabrication hole.
Said eccentric hold-down mechanism comprises abacus bead shape eccentric cam and is fixed into whole handle with it, is provided with the adjustment stop screw between said abacus bead shape eccentric cam and the riser.
The rapid-mounted mechanism quantity on said riser top at least one.
Beneficial effect: convenient and swift, production efficiency is high than the fastening frock of traditional standard spare, thrust is balanced reliable.Through the adjustment stop screw, can guarantee that clamping force is even.Improve 50-60% than efficient before improving.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the vertical view (two groups of rapid-mounted mechanisms of middle omission) of Fig. 1;

Among the figure: 1, base plate, 2, riser, 3, go up movable presser feet, 4, movable presser feet down, 5, square groove; 6, workpiece alignment pin, 7, paw, 8, fabrication hole, 9, abacus bead shape eccentric cam; 10, handle, 11, the adjustment stop screw, 12, industrial sewing machine freely presses first, 13, bearing pin.
The specific embodiment
Below in conjunction with preferred embodiment; To details are as follows according to the specific embodiment provided by the invention: see accompanying drawing for details; A kind of industrial sewing machine is freely pressed the machining fixture of unit, comprises base plate 1, riser 2 and rapid-mounted mechanism, and said riser is connected with the base plate vertical fixing; Said riser top is provided with rapid-mounted mechanism; Said rapid-mounted mechanism comprises two parallel last movable presser feets 3 and down movable presser feet 4, eccentric hold-down mechanism, and said riser is provided with the square groove 5 that is slidingly connected with last movable presser feet and movable presser feet down, correspondingly on the said riser movable presser feet and is provided with workpiece alignment pin 6 between the movable presser feet down; Said movable presser feet is provided with the paw vertical with its body 7 with following movable presser feet front end; Said movable presser feet is with movable presser feet rear end is through bearing pin 13 and eccentric hold-down mechanism pin joint down, and said movable presser feet is provided with fabrication hole 8, convenient boring and fraising with the corresponding location of workpiece of down movable presser feet front end.Said eccentric hold-down mechanism comprises abacus bead shape eccentric cam 9 and is fixed into whole handle 10 with it, is provided with adjustment stop screw 11 between said abacus bead shape eccentric cam and the riser.The rapid-mounted mechanism quantity on said riser top at least one.Present embodiment is four rapid-mounted mechanisms.
The course of work:
When handle is threaded to the A position; Abacus bead shape eccentric cam edge and workpiece alignment pin distance diminish; Going up movable presser feet then moves by direction as shown in the figure with following movable presser feet; Go up distance increase between movable presser feet and following movable presser feet and riser, with freely pressing unit to insert workpiece alignment pin 6, promptly fixable/dismountable workpiece along its elongated slot.When handle was threaded to the B position, abacus bead shape eccentric cam edge and workpiece alignment pin were gone up movable presser feet and are then moved by direction as shown in the figure with following movable presser feet apart from increase, and upward distance diminishes between movable presser feet and following movable presser feet and riser, thus workpiece pressing.It is firm, simple and efficient that the method compresses.And the eccentric cam edge is abacus bead shape, can correspondingly regulate the upper and lower movable presser feet and the thrust of movable presser feet down of voluntarily, makes the workpiece stress equalization.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
