Abstract

The utility model relates to a connection joint for the embroidery frame of a computer embroidery machine and the frame of a small inside embroidery frame. The utility model is composed of two clipping blocks with circular arc grooves, fastening screws for fastening the two clipping blocks, a positioning pin, a fulcrum and a bending plate by which the small embroidery frame and the clipping blocks are connected via screws. The connection joint can be used by matched with the embroidery frame with an integral structure and can also be used for the existing embroidery frame (side strips are not detached). The stiffness of the embroidery frame is enhanced by adopting the connection joint, and thus embroidery precision is further enhanced. The circular arc grooves of the two clipping blocks are clamped on the hollow tube of the embroidery frame, and the clipping blocks can be shifted along a circular tube for the convenience of adjusting the position of the frame of the small embroidery frame.

Description

Connecting joint for small embroidering frame of computer embroidering machine

The utility model is the connecting joint of the framework of a kind of tabouret of multi-head computerized embroidery machine and inner little tabouret.

The tabouret of multi-head computerized embroidery machine is a larger-size aluminium section bar rectangular configuration framework, for the less embroidery of will embroidering, various circles, the little tabouret of rectangle or oval-shaped inside must be fixed on the tabouret.The tabouret of the multi-head computerized embroidery machine of day Honda island TAJAMA reaches 5 meters, widely reach 0.95 meter, it is to be installed in the little tabouret in inside on the timber framework or to be installed in the auxilliary of plastics to penetrate on the grid framework, is being fixed on the tabouret with screw by the journal stirrup that is fixed on the framework then.The tabouret of this kind connecting mode must be made the combined type tabouret of being made up of main body frame and edge strip framework, and this combined type tabouret manufacturability is bad, the cost height; When embroidery is made little embroidery, must roll over the edge strip on the tabouret fall, the screw that utilizes fixing edge strip is with the main body frame and the timber framework of tabouret or assist the journal stirrup of penetrating grid framework and be fixed together.This kind connecting mode the more important thing is because folding removes edge strip the integral rigidity of tabouret is descended that except because of folding will unload tens screws extremely bother except that 5 meters long edge strips influence is embroidered and made precision, is folded down edge strip and is difficult for keeping, and easily cause distortion.

The purpose of this utility model is a kind of special joint of design, and it not only can be applicable on the monoblock type tabouret of the applicant's design, also can be applicable on the existing combined type tabouret, and no longer folding removes edge strip, has overcome the weak point of prior art.

The utility model is to have adopted following scheme:

The joint that the tabouret of computer embroidering machine of the present utility model connects with the framework of little tabouret, contain the screw that connects with the journal stirrup of small embroidering frame, the fixture block of two symmetries that have the arcuation groove that are complementary with the hollow pipe of tabouret, make two groove clamping tabouret hollow pipes of symmetry and tighten up the screw of two fixture blocks, by the bent plate of screw attachment small embroidering frame journal stirrup and fixture block.

The utility model is accurately convenient for the hollow pipe that makes two fixture block clamping tabourets, can adopt the top between two fixture blocks to be provided with a fulcrum, and respectively be provided with in the both sides of the screw of clamp block and insert pin in two fixture blocks and that make it Primary Location, post pad on the arc groove cambered surface of fixture block.

Fulcrum between two fixture blocks of the present utility model can realize that the top fulcrum between two fixture blocks is the steel wire that is embedded in a fixture block top by following scheme.

Fulcrum between two fixture blocks of the present utility model is made of the projection of two fixture blocks upper end, and the fixture block shape as shown in Figure 3.

The utility model can with the supporting use of overall structure tabouret (existing main body frame and edge strip framework are integrated) of the applicant design, also can directly apply to existing tabouret, need not roll over, the rigidity of tabouret is increased, improve to embroider and made precision except that edge strip.Connecting joint of the present utility model in addition connects with the tubular lobes of tabouret, and this connecting mode can move the circular-arc groove of joint along the pipe of tabouret, is convenient to regulate the position of small embroidering frame, and itself and embroidery head are aligned.

The utility model description of drawings is as follows:

Fig. 1 is the installation diagram of connecting joint of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 has the fixture block schematic diagram of projection for the upper face of arc groove side.

Specify the structure of present embodiment below in conjunction with accompanying drawing 1 and accompanying drawing 2.

Present embodiment is made up of screw (2), bent plate (3), screw (4), fixture block (6) and (10), steel wire (7), pad (8), pin (14) and screw (15).Two fixture blocks (6) and (10) likeness in form one cuboid Lower Half one side fall in an arc groove (9), arc should be complementary with the pipe shape projection (11) of tabouret, the arc groove (9) of two fixture blocks (6) and (10) is oppositely arranged combination, pipe shape projection (11) for the firm grip tabouret, the arc-shaped slot that two fixture blocks (6) and (10) are constituted is super semicircle, and posts pad (8) on the cambered surface of deep-slotted chip breaker (9).On the position of pushing up near circular groove (9), fixture block (6) has tapped through hole (12), and fixture block (10) has the stepwise through hole, and joint bolt (15) is set in tapped through hole (12) and the stepwise through hole; Tapped through hole (12) both sides of fixture block (6) respectively have cylindrical hole (13), the stepwise through hole both sides of fixture block (10) respectively have pin-and-hole, pin (14) stationary fit is in the pin-and-hole of fixture block (10), stay in the cylindrical hole (13) of through hole outer part pin movable insertion fixture block (6), two pins (14) make two fixture blocks (6) and (10) Primary Location, when unclamping the screw (15) that tightens up two fixture blocks, two fixture blocks (6) can be relative to producing bigger rotating with (10).In the top madial wall of fixture block (10) axially on inlay the fulcrum that a steel wire (7) moves as two fixture blocks (6) and (10) open and close.Two tapped through holes (5) are being opened in the appropriate location of the top of the tapped through hole (12) of fixture block (6), the vertical end of bent plate (3) has two through holes, horizontal end has a tapped through hole, crossing tapped through hole (5) and bent plate vertical end through hole is fixed on the fixture block (6) with the vertical end of screw (4) with bent plate (3), through hole and the horizontal end tapped through hole of bent plate of crossing small embroidering frame journal stirrup (1) anchor at small embroidering frame and bent plate (3) together with screw (2), thereby small embroidering frame and computer embroidering machine tabouret are linked together.
