Description

Technical Field

[0001] This utility model relates to the field of large circular knitting machine technology, and more specifically to a high-precision large circular knitting machine triangle. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have seen rapid development due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability. The knitting mechanism is the heart of the circular knitting machine, mainly composed of the cylinder, needles, cams and cam seats (also called saddles), and sinkers; the cams are also called corner pins or rhombus pins. They control the reciprocating motion of the needles and sinkers within the cylinder groove according to the different knitting patterns required by the circular knitting machine.

[0003] Currently, the machining of the boss and outer contour of the existing triangular part is separate. The boss and fixing hole are machined first, and then the outer contour and needle rail groove are machined through the fixing hole. This makes it difficult to guarantee the workpiece accuracy and the separate machining is inefficient. Therefore, it is necessary to improve the structure. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision large circular knives in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A high-precision large circular kinematic machine caliper includes a caliper body. From top to bottom, the caliper body has a fixing hole, a needle rail groove, and a first process pin hole. A positioning boss is provided on the outside of the fixing hole, and a second process pin hole is provided on the right side of the positioning boss. The positioning boss is rectangular in shape, has an internal groove, and communicates with the fixing hole.

[0007] The line connecting the centers of the fixing hole and the first process pin hole passes through the highest point of the pin rail groove wave crest.

[0008] The angle between the line connecting the centers of the second process pin hole and the fixing hole and the horizontal line is 9°.

[0009] The distance D1 between the centers of the second process pin hole and the fixing hole and the distance D2 between the centers of the fixing hole and the first process pin hole are 1:3.

[0010] The left edge of the triangular body is chamfered. The chamfer is 120°, and the purpose of the chamfer is to facilitate the smooth passage of the needle.

[0011] The triangular body has a protrusion at its left end and a groove on its right side, with the protrusion and groove matching in shape. The protrusion ensures that adjacent triangular bodies fit tightly together, preventing slippage between them.

[0012] The triangle body is connected to the machining table through the fixing hole, the first process pin hole, and the second process pin hole. The stability of the triangle body is improved by three-point positioning, which avoids the triangle body from shaking. The positioning boss, outer contour and pin rail groove are machined as a whole in one go, avoiding separate machining, thus improving machining accuracy and production efficiency.

[0013] In use, the triangular body is installed on the large circular knitting machine through the fixing hole, the first process pin hole, the second process pin hole and the positioning boss. Alternatively, it can be connected and fixed to the large circular knitting machine through the fixing hole and the positioning boss. The method is flexible. If the connection method of fixing hole and positioning boss is adopted, the other first process pin hole and second process pin hole can also be used as oiling holes.

[0014] In this invention, the angle parameter between the line connecting the centers of the second process pin hole and the fixed hole and the horizontal line, as well as the ratio of the distance between the centers of the second process pin hole and the fixed hole to the distance between the centers of the fixed hole and the first process pin hole, are set to better connect and match with the processing table to provide processing accuracy.

[0015] The beneficial effects of this utility model are as follows:

[0016] The triangle body is connected to the machining table via a fixed hole, a first process pin hole, and a second process pin hole. Three-point positioning improves the stability of the triangle body and prevents it from shaking. The positioning boss, outer contour, and pin rail groove are machined as a whole, avoiding separate machining and improving machining accuracy and production efficiency. The first and second process pin holes can also be used as oil filling holes. The protrusions ensure that adjacent triangle bodies fit tightly and prevent slippage between them.
