Abstract
The utility model discloses a needle board or needle tube assembly which comprises the needle board, the needle tube and a card grinding. The needle tube is arranged on the needle board. The needle tube comprises an inner tube and an outer tube sleeved on the outer wall of the inner tube. The card grinding is arranged in the inner tube, and a screw is arranged at the front end of the inner tube and fixedly connected with the inner tube. A screw is arranged on the tail end of the outer tube and fixedly connected with the outer tube. The needle board or needle tube assembly is capable of improving utilization rate of the card grinding, and sending operation of the card grinding is convenient.
Description
Technical field
The utility model relates generally to the needle plate of doing the processing of drawing-die tool/needle tubing fixture.
Background technology
When the drawing-die tool is done in workshop processing, need to use the card grinding of 8mm, this card grinding adds that diamond cream grinds, and the compression angle of mould depends on the angle of card grinding fully.It is fixing that this needs needle plate and needle tubing assembly card grinding to be processed and repaired angle etc.In existing needle plate and needle tubing assembly, card grinding is inserted in needle tubing, and card grinding and needle tubing is fixed by screw at the two ends of needle tubing.But after the card grinding wearing and tearing, just need to unclamp screw card grinding is given forward, after giving over certain distance, card grinding tail end integral body enters into needle tubing, and this moment, the card grinding tail end can't be fixed, and can only scrap, and therefore caused the card grinding utilization rate low, and processing cost is too high.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model has been to provide a kind of needle plate/needle tubing assembly, makes the utilization rate of card grinding higher, has reduced processing cost.
Technical scheme: for achieving the above object, the utility model is by the following technical solutions: a kind of needle plate/needle tubing assembly, comprise needle plate, needle tubing and card grinding, and described needle tubing is located on needle plate, this needle tubing comprises inner tube and the outer tube that is enclosed within this outer wall of inner tube, and described card grinding is inserted in inner tube; Described inner tube front end is provided with screw and card grinding is fixedly connected with inner tube, and described outer tube tail end is provided with screw and inner tube is fixedly connected with outer tube.
Further improve, described inner tube front end stretches out outer tube, thereby screwed hole can directly be set on inner pipe, and screw coordinates screw-in with screwed hole, and then card grinding is withstood fixing.When therefore being arranged on needle tubing on needle plate, the inner tube front end can expose needle plate, facilitates giving of card grinding.
Further, described outer tube tail end is removably connected with the ring piece, screw is set on this ring piece and inner tube is connected with outer tube.The screw of tail end is located on the ring piece, not only inner tube can be fixedly connected with outer tube, avoided simultaneously the fastened by screw difficulty that causes when dislocation occurs inner and outer tubes.
As preferably, described needle plate is provided with many trocar tubes side by side.
Beneficial effect: compared with prior art, the utlity model has following advantage: can improve the utilization rate of card grinding, and facilitate the operation of giving of card grinding.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of needle tubing described in the utility model.
Wherein, card grinding 1, inner tube 2, outer tube 3, ring piece 4, screw 5, needle plate 6.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Fig. 1～2, a kind of needle plate 6/ needle tubing assembly comprises needle plate 6, needle tubing and card grinding 1, and wherein needle tubing comprises inner tube 2 and outer tube 3, and described outer tube 3 closely is enclosed within on the outer wall of inner tube 2, and outer tube 3 is stretched out at inner tube 2 two ends; Described card grinding 1 is inserted in inner tube 2; Evenly be provided with 3 screws 5 on inner tube 2 front end outer walls, thereby this screw 5 holds out against card grinding 1 makes card grinding 1 be fixedly connected with inner tube 2, and cover has ring piece 4 on inner tube 2 tail ends, this ring piece 4 is threaded with outer tube 3 tail ends simultaneously, and 3 screws 5 equally evenly are set at ring on piece 4 and hold out against inner tube 2, thereby make inner tube 2 be fixedly connected with outer tube 3.Then so a plurality of needle tubings are inserted on needle plate 6, and hold out against outer tube 3 in needle tubing with screw 5 equally, prevent to add the vibration in man-hour excessive.
By above-mentioned improvement, 1 of card grinding needs the front terminal screw 5 of inner tube 2 and coordinates inner tube 2 to fix, even therefore card grinding 1 wearing and tearing rearward end is given and is entered into inner tube 2, still guarantee that card grinding 1 can work, with respect to prior art, the use amount of the card grinding 1 of every 8mm is brought up to 115mm by 30mm, thereby has greatly improved the utilization rate of card grinding 1.
