The heald frame guide rail comprises a heald frame bracket, wherein a guide rail seat is fixed onto the heald frame bracket; side guide rails are arranged on the two sides of the guide rail seat respectively; multiple middle guide rails are arranged between the two side guide rails; the two side guide rails and the multiple middle guide rails are arranged at equal intervals to form multiple sliding grooves; and each sliding groove is 8 plus or minus 0.012 mm in width and 250 mm in length. According to the heald frame guide rail, upper and lower heald frame guide racks in the prior art are changed into a continuous sliding rail comprising the guide rail seat, the side guide rails and the middle guide rails, and the sliding groove is 8 plus or minus 0.012 mm in tolerance, so that the precision is improved; a layer of air film is generated between a heald frame and the heald frame guide rail by the existing air source through the air cushion, so that the heald frame is guaranteed to stably run on the heald frame guide rail; and the heald frame guide rail has the advantages of good reliability and long service life.
Description
Technical field
The invention belongs to loom field, relate to brown frame, in particular to a kind of brown frame guide rail.
Background technology
Shedding mechanism operation process in dynamic force and dynamic force moment very large.Use the passive open loop system of return spring, the instantaneous rising of inertia force meeting, when overcomes spring constraint power, roller follower is instantaneous disengagement from cam face, tripping and impact cause heald frame strongly to rock, and result heald frame rocks back and forth with heald, frequently occur warp break fault.
Yet, shown in Fig. 1, Fig. 2, for the heald frame saddle now using on loom, on heald frame saddle, have 10 saddle grooves, heald frame pumps in saddle groove, 18 millimeters of heald frame saddle thickness, heald frame saddle uses bolted on support of heald frames, totally 2 up and down of heald frame saddles, 4 of both sides, 214 millimeters of upper and lower 2 heald frame saddle spacing.The movement limit of heald frame side shelves is in corresponding saddle groove, and heald frame saddle has only limited the swing of side shelves, prevents that the heald frame of motion from colliding mutually, allows heald frame to rock in saddle.Heald frame saddle just plays the effect of plate washer, and restriction integrated box movement, separates ten pages of heald frames, not as motion guide rail.
Summary of the invention
For overcoming deficiency of the prior art, object purport of the present invention provides a kind of head frame guides with air cushion for air-jet loom, to guarantee heald frame even running on head frame guides.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of head frame guides with air cushion, comprise a brown frame bracket, on described brown frame bracket, be fixed with track base, the both sides of described track base are respectively arranged with side rails, between two described side rails, be provided with several middle guide rail, two described side rails and several middle guide rail equi-spaced apart are arranged, are formed some chutes, the width of every described chute is 8 ± 0.012mm, and length is 250mm.
Further, described middle guide rail comprises a middle guide rail body, the centre of the two sides of described middle guide rail body offers respectively a rectangular channel, the both sides of described rectangular channel are respectively the rectangular cavity being opened on described middle guide rail body, are provided with the air cushion that several can eject air-flow in described rectangular cavity; Described side rails comprises a side rails body, and the structure on the side of the structure on the medial surface of described side rails body and described middle guide rail body is identical.
Further, the centre of described air cushion is a cavity, and the surrounding of described cavity is furnished with several jet-impingement mechanisms, and described jet-impingement mechanism consists of several throttle orifices; Compressed Gas enters described air cushion through described middle guide rail body and side rails body, then spouting from several described throttle orifices.Air-flow acts on after spraying from throttle orifice between guide rail and heald frame side shelves, in 10 gaps, forms air film.
Compared with prior art, the present invention has following beneficial effect:
The present invention makes upper and lower two heald frame saddles in prior art into one by track base, side rails, and the elongated slide rail of middle guide rail formation, tolerance 8 ± the 0.012mm of chute, improve precision, and utilize existing source of the gas by air cushion, to produce one deck air film between heald frame and head frame guides, guarantee heald frame even running on head frame guides, and there is good reliability and service life.
Stroke of harness frames surpasses 120mm, and the length of head frame guides is 250mm, belongs to long stroke guide rail.With air cushion, as guide rail support, the compressed gas that source of the gas is provided can be converted into the supporting force of guide rail.In shedding mechanism, every page of heald frame stressed 300 KG that reach in the direction of motion, the about 10KG of quality of heald frame, the direction of head frame guides holding capacity is perpendicular to the direction of motion, and mainly stressed is that heald frame rocks impulsive force.Heald frame maximum rock the minimum and extreme higher position that occurs in heald frame, lift or fall journey finish after heald frame high vibration, now air cushion supporting is enough to bear and cushion acutely rocking of heald frame.
With the running status of the head frame guides of air cushion, for the mechanism design of high-speed weaving machine provides data, adjust the technological parameters such as relevant air pressure and flow, the vibration in buffering integrated box movement.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
