High-speed testing device for harnessstrings spring

Abstract

The invention discloses a high-speed testing device for a harnessstrings spring. The high-speed testing device comprises a stand, wherein a motor is arranged on the top of the stand; an output end of the motor is connected with an eccentric wheel; the eccentric wheel is connected with a transmission shaft; the transmission shaft is connected with a sliding shaft; the sliding shaft is radially fixed on the stand; a harnessstrings fixing frame is fixed on the sliding shaft; hook clips are arranged on the harnessstrings fixing frame; connector hooks are fixed on the hook clips; quick connectors used for connecting harnessstrings are connected to the connector hooks; a stringing plate and a comber plate frame successively penetrated through by the harnessstrings are arranged below the quick connectors; stringing holes are formed in the stringing plate; oillets are formed in the comber plate frame; and a return heald frame for fixing the spring is arranged on the bottom of the stand. By utilizing the high-speed testing device for the harnessstrings spring, the reciprocating motion of the harnessstrings spring can be realized at high speed, the testing result is greatly shortened, and the spring can be selected under the condition of high-speed operation because a transmission mechanism is simple and direct.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a testing machine for springs on harness wires. Background technique [0002] At present, all kinds of jacquard machines and textile machines have supporting harnesses, which are used to continuously raise and lower the warp during the weaving process. like figure 1 , the harness assembly generally includes a harness thread 101, a heald rod 102, a heald 103, and a spring 104. One end of the heald rod 102 is connected to the wire 101, and the other end is connected to the heald 103. The heald 103 is connected to the spring 104, and the heald The rod 102 is provided with a heddle eye 105, and the warp thread used for weaving passes through the heddle eye 105. During the weaving process, the warp thread is continuously lifted and lowered by pulling the harness thread 101. During the lifting and lowering process of the harness thread, The spring 104 connected to the heddle 103 play...

AI Technical Summary

Problems solved by technology

Since the spring is continuously pulled up and restored, there are high requirements for the strength of the spring and other indicators. Every time a batch of springs are used, they need to be tested first. Originally, the test could only be done manually. Judgment, the test time is longer

The patent number applied by the applicant is 201220161399.8, and the patent name is "a kind of wire spring testing equipment" discloses a kind of equipment for testing the wire spring, but due to the complexity of its transmission mechanism, during use The effect is not good and cannot meet the requirements of high-speed testing
