Description
Technical field
The utility model relates to a kind of heald frame that is applied on the air-jet loom.
Background technology
Heald frame on the air-jet loom is the workpiece of shedding mechanism, and heald frame is installed between loom opening drive apparatus and the return device.Heald frame is thin type frame clsss parts, the about 10～14mm of heald frame thickness, the about 2000～3200mm of length.Heald frame bears warp tension, and every page of heald frame drives about 2000 warp thread, the warp thread load of bearing 1000N approximately.The shedding mechanism of air-jet loom is the mechanical structured member of working condition extreme difference, and the elementary model frequency of heald frame is lower than 10Hz, and the about 10～15Hz of the operating frequency of air-jet loom, the heald frame and the shedding mechanism of air-jet loom move in resonance region.
When loom runs up, as the vibration shape of accompanying drawing 3～5 expression heald frames, from the visible crossbeam of the vibration shape with the side shelves twist and crooked.Former rank mode of heald frame is based on the crooked vibration shape, the middle part of crossbeam and the both ends of crossbeam are than the large amplitude point, and on crossbeam and side shelves faying face, crossbeam exists the different vibration shape and amplitude with the side shelves, crossbeam and side shelves have the direction of motion separately, and the framework of heald frame is torn.The side shelves of heald frame move up and down along combining the frame chute, very big amplitude can occur at the middle part of heald frame; When weaving plain cloth, the phase difference of adjacent two heald frames is 180 °, and the motion severe interference of adjacent heald frame causes the heald frame middle part to mill and fracture.
In the prior art, because the used in jet loom heald frame drives warp thread and moves up and down, the structure of heald frame was to satisfy heald frame member bonding strength in the past, do not consider to do between crossbeam and the side shelves to rotate and be shifted, so heald frame produces excessive deformation owing to hiding system vibration relative to trace.And the warp on loom broken end mainly occurs in the heald frame adjacent domain, heald frame has been given warp thread violent vibration transfer, aggravated the friction of warp thread in harness eye, heald frame vibration causing the greatly not cleer and peaceful warp end break of opening, when loom rotating speed and the former rank of heald frame intrinsic frequency near the time, fracture can take place or fall apart in heald frame.Therefore, when increasing heald frame rigidity and alleviating its quality, the heald frame design must improve its dynamic property, improves vibration absorption ability.
The utility model content
The purpose of this utility model provides the heald frame that a kind of vibration that can absorb effectively between crossbeam and the side shelves prevents excessive deformation, it can adapt to the adaptive capacity of the high-speed cruising enhancing shedding mechanism of loom, the fault rate that significantly reduces end breakage and reduce shedding mechanism.
The utility model can be implemented by the following technical programs: a kind of used in jet loom heald frame, it comprises entablature, sill and connects left side shelves and right side shelves on described entablature, the sill, be connected by Flexible Connector between described entablature, sill and left side shelves, the right side shelves, the twist and warping energy of the small deformation of crossbeam and side shelves is absorbed by Flexible Connector like this.
Described Flexible Connector comprises that being arranged on described entablature, sill is connected the joint with elastomeric pad between left side shelves, the right side shelves with elasticity.
The cross section that described elasticity connects the joint is a kind of in circle or ellipse or the convex outer curve shape.
Described elastomeric pad is connected the joint with elasticity making material is a non-metallic elastic material.
Compared with the prior art the utility model has following advantage:
Be rigidly connected differently with of the prior art, the elasticity that is connected to the band certain flexibility of crossbeam of the present utility model and side shelves is connected, and the small deformation of crossbeam is absorbed by elastomeric pad, and the twist and warping of side shelves are also absorbed by elasticity connection joint.Elastomeric pad is connected being used in combination of joint with elasticity, the space of fine motion is provided for crossbeam and side shelves on three directions, and the elasticity of two parts connects flexural vibrations and the torsional oscillation that has relaxed heald frame, and the vibration of crossbeam and side shelves is by effective isolation.
Compared with prior art, utilize the Flexible Connector between the heald frame member to absorb vibration, so heald frame vibration minimizing, the friction of warp thread in harness eye reduces, and reduced the end breakage rate of warp thread, reduced the stop over number of times of loom.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated:
As shown in Figure 1, a kind of used in jet loom heald frame, it comprises entablature 1, sill 2 and connects left side shelves 3 and right side shelves 4 and guide plate 6 on described entablature 1, the sill 2, the frame structure of heald frame mainly by lower and upper cross-member and about two side shelves constitute.The aluminium alloy extruded flat tube of the entablature 1 of aluminium alloy heald frame, the special proportioning of sill 2 usefulness is made.About 10～the 14mm of the thickness of heald frame, the about 2100～3200mm of length, highly about 300～500mm, adjacent two pages of heald frames separate to alleviate the heald frame heavy curtain moving with guide plate 6, and reduce the friction between the adjacent heald frame.Every side shelves respectively with the lower and upper cross-member Bolt Connection.
Owing to heald frame is the workpiece of loom open loop system, system is subjected to the impact of camming movement, and vibration can't be hidden by system, and structure and the boundary condition that therefore need improve heald frame vibrate with reducing to change the vibration shape.The utility model is at the twist and warping vibration shape of heald frame mode, behind the position of determining peak swing and maximum stress in bend, in order to reduce the amplitude of framework as much as possible, prevent the excessive deformation of heald frame, strain energy with the Flexible Connector between the heald frame main member absorbs vibration, promptly is provided with Flexible Connector 5 between described entablature 1, sill 2 and left side shelves 3, right side shelves 4.
