Abstract

The utility model relates to a mechanical equipment specifically is the lift pull rod and the pull rod joint of ring collar of spinning machine ring spinning frame and thread guide. The ring spinning frame is a long-direction device, the pull rods are connected section by section, the ring plate and the yarn guide plate are driven to reciprocate up and down in the whole spinning process to complete the winding and forming of the yarn, and the pull rods are increased from 15 sections of the original whole device to about 60 sections along with the lengthening of the device. In the existing design, the pull rod is tightly connected with the pull rod joint through a screw, and the pull rod can move in relative position and deform a hole in the long-term stress movement process, so that the total length of the pull rod is extended, and the yarn quality is influenced. The utility model provides a new pull rod and pull rod connect has the location protruding on the pull rod connects, and the relevant position has the constant head tank on the pull rod, through the protruding cooperation with the constant head tank in location, and long to not taking place relative displacement in the pull rod motion process guarantees that the yarn quality is not influenced.

Description

Pull rod and pull rod joint

Technical Field

The utility model relates to a mechanical equipment specifically is lift pull rod and pull rod joint of ring collar of spinning machine ring spinning frame and thread guide.

Background

The ring spinning frame is a long-direction device, and as for domestic equipment, the ring spinning frame mainly takes 516 spindles or less before 2000 years, the equipment is gradually lengthened to 1200 spindles along with the improvement of the overall level of the textile machinery industry, and part of the equipment is lengthened to 1824 spindles and even exceeds 2000 spindles. The pull rod of the ring spinning frame drives the whole ring rail and the yarn guide plate to reciprocate up and down to complete the winding and forming of the yarn in the whole spinning process through the traction belt connected to the upper part of the pull rod, the left and right of the pull rod is increased to nearly 60 sections from 15 sections of the original whole device along with the lengthening of the device, and the stress of the pull rod connected section by section can generate relative displacement in the spinning process, so that the three concentricity of the ring, the spindle and the yarn guide hook is damaged, and the yarn forming quality is influenced. In the existing design, a pull rod is connected with a pull rod joint in a tightening mode through screws, equipment is lengthened, some mechanical manufacturers lengthen the pull rod joint to reduce accumulated errors in the length direction of the pull rod, and two connecting holes are changed into four connecting holes. However, the defects still remain after further research, mainly comprising the following steps: the relative position of the pull rod and the pull rod joint moves in the long-term stress movement process of the pull rod, so that the total length of the pull rod is extended, errors are accumulated, the yarn forming quality is influenced, and the longer the device is, the more serious the influence is.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pull rod and pull rod joint of ring-spinning frame for solve traditional pull rod and pull rod joint and draw the relative displacement problem that the force in-process caused for a long time.

For solving the above problems, the technical proposal of the utility model is that: the pull rod joint comprises a pull rod joint body, a connecting hole is formed in the pull rod joint body, a positioning bulge is further arranged on the pull rod joint body, and the pull rod is provided with the connecting hole matched with the pull rod joint and the positioning groove matched with the positioning bulge.

The positioning bulge on the pull rod joint and the pull rod joint body are of an integrated structure.

The pull rod joint positioning bulge is of a cuboid or cylindrical structure, and can also be of other structures.

The pull rod is provided with a positioning groove corresponding to the joint bulge of the pull rod.

The pull rod positioning groove is matched with the positioning bulge on the pull rod joint to form a square or a round shape.

The utility model has the advantages that: the pull rod and the pull rod joint are accurately positioned, and the relative displacement is not generated after long-term use.

FIG. 2 is a schematic view of an original pull rod;

FIG. 3 is a schematic view of an original tie-rod joint;

FIG. 4 is a schematic view of the pull rod and pull rod joint combination according to the present invention;

FIG. 5 is a schematic view of the pull rod of the present invention

Figure 6 is a schematic view of the pull rod joint of the present invention

The specific implementation mode is as follows:

FIG. 1 is a schematic view of a tie bar joint of an original ring spinning frame, wherein when two tie bars are connected, 4 connecting holes on the tie bar joint are respectively aligned with corresponding connecting holes on the two tie bars, and then are tightly connected by screws. Due to the long-term tensile force of the tie rod, the tie rod and the tie rod joint are relatively displaced at the connecting part, so that the length of the tie rod in the length direction changes.

As shown in fig. 3, which is a schematic view of the combination state of the improved tie rod and tie rod joint, when connecting, the protrusions on the tie rod joint are inserted into the positioning grooves of the two tie rods, and then connected at the connecting holes by screws.
