Abstract

The utility model discloses a hole opening auxiliary device for a needle plate of a flat knitting machine. The hole opening auxiliary device comprises a guide seat. Three positioning holes are formed in the guide seat. A locking part and a cone shaft are respectively arranged in two positioning holes. The positions and the sizes of the positioning holes are the same as the design positions and the design sizes of pin holes in the needle plate. The hole opening auxiliary device for the needle plate of the flat knitting machine can be used for effectively ensuring the hole opening quality of the third pin hole, not only is convenient and rapid to operate, but also is accurate in positioning, and thus, not only is the working efficiency greatly improved, but also the rejection rate and the production cost of the needle plate are reduced.

Description

Flat machine needle plate perforate servicing unit

Technical field

The utility model relates to technical field of knitting machinery, particularly relates to a kind of flat machine needle plate perforate servicing unit.

Background technology

At present, in the manufacture process of flat machine, to open three pin-and-holes on the needle plate, the position of three pin-and-holes and size be through operating personnel according to design attitude and design size, utilize and confirm behind the gage measuring.Yet because operating personnel are different, it is also different that it measures gimmick; Position and the size of measuring pin-and-hole at last also exist error, particularly after ending two pin-and-holes, in the time of need opening the 3rd pin-and-hole; Bigger error appears in the position of the 3rd pin-and-hole and size easily, not only can reduce the efficiency of assembling of equipment, also causes needle plate to be scrapped easily; Cause economic loss, improve production cost; Simultaneously, the efficient of manual measurement is lower, also is awkward.

The utility model content

The purpose of the utility model provides a kind of flat machine needle plate perforate servicing unit that can effectively guarantee the perforate quality of the 3rd pin-and-hole.

For this reason; The technical scheme that the utility model adopted is such: flat machine needle plate perforate servicing unit; It is characterized in that: it comprises a holding support; Have three locating holes on the holding support, wherein be respectively equipped with a locking member and an axis of cone in two locating holes, the design attitude and the design size of pin-and-hole are identical on the position of locating hole and size and the needle plate.

In the time need on the needle plate that has two pin-and-holes, opening the 3rd pin-and-hole; Can be earlier holding support be placed on the required needle plate of opening the 3rd pin-and-hole, earlier through the axis of cone with holding support and needle plate correcting, follow with locking member and make holding support and needle plate fastening; Fastening torsion is 25～30Nm, takes off the axis of cone; Utilize drilling tool to carry out perforate then; Perforate is unclamped locking member after accomplishing, and takes off the holding support that is placed on the needle plate and gets final product.

The utility model can effectively be guaranteed the perforate quality of the 3rd pin-and-hole, both simple operations, and accurate positioning has again not only improved operating efficiency greatly, has also reduced the scrappage and the production cost of needle plate.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Fig. 1 is the holding support structural representation.

Fig. 2 is the needle plate structure sketch map.

Fig. 3 is the utility model user mode figure.

The specific embodiment

Referring to Fig. 1 and Fig. 2, Fig. 1 embodiment comprises a holding support 1, and the cross section of holding support 1 is down " recessed " font, has two sidewalls; Holding support 1 has first locating hole 21, second locating hole 22 and the 3rd locating hole 23 from right to left successively between two sidewalls.

Referring to Fig. 1, Fig. 2 and Fig. 3.Present embodiment operating procedure in use is following:

1, holding support 1 is placed on the needle plate 2; First pin-and-hole 11 and second pin-and-hole 12 have been had on the needle plate 2;

2, get first locating hole 21 that an axis of cone 3 is passed holding support 1, penetrate in first pin-and-hole 11, and tangent with first pin-and-hole 11, holding support 1 and needle plate 2 are carried out correcting;

3, get a locking member 4 and pass second locating hole 22 and second pin-and-hole 12, holding support 1 and needle plate 2 is fastening, and fastening torsion is 28Nm;

4, extract the axis of cone 3 out;

5, use power drill to join the drill bit of diameter as 8mm, drill bit stretches in the 3rd locating hole, on needle plate and the corresponding position of the 3rd locating hole, carries out perforate;

6, after perforate was accomplished, the locking member 4 that comes loose took off the holding support 1 that is placed on the needle plate 2.

After the completion, as shown in Figure 2, needle plate 2 is arranged in order first pin-and-hole 11, second pin-and-hole 12 and the 3rd pin-and-hole 13 from right to left, and design size is 8mm, and the design attitude and the design size of pin-and-hole are identical on the position of locating hole and size and the needle plate 2.

Claims

1. flat machine needle plate perforate servicing unit; It is characterized in that: it comprises a holding support; Have three locating holes on the holding support, wherein be respectively equipped with a locking member and an axis of cone in two locating holes, the design attitude and the design size of pin-and-hole are identical on the position of locating hole and size and the needle plate.
