Abstract
The utility model provides a guide-rail device for weaving machine, which comprise a guide rail and moving pieces; the guide rail is provided with an air cavity, and the air cavity is provided with anair mouth, both ends of the air cavity are mounted with air cavity cover board for sealing, the working surface where the guide rail matches with the moving pieces is opened with a plurality of air outlets, wherein, the air mouth is arranged at one side of the guide rail and is connected with an air supply mechanism, the air cavity cover board is fixedly connected with the end surface of the guide rail through a screw. The guide-rail device for weaving machine utilizes the principle of gas suspension, which makes the periphery of the moving pieces have filled gas during the high-speed reciprocating motion of the moving pieces and makes the moving pieces do not contact with sword rail body, therefore, the friction of the moving pieces is greatly reduced, and the vibration of the moving pieces is greatly decreased, meanwhile, the directivity of the moving pieces during moving in the guide rail is ensured, thereby ensuring the reliability of the conjoining latitude, and the utility modelfacilitates the increasing of the rotate speed of the weaving machine, the increasing of the production efficiency, the extending of the service life of the moving pieces, the reducing of the production cost, and the increasing of the economic benefit.
Description
Technical field
The utility model relates to the Rapier looms technical field, particularly a kind of track-type facilities that is used for weft inserting apparatus for a rapier loom.
Background technology
The rapier loom weft insertion system is made up of sword actuation, sword belt wheel, sword belt, guide rail and the first-class part of sword, the main effect of its middle guide is the direction of motion of determining sword head and sword belt, drive the sword belt wheel by the sword belt actuation, drive sword belt by the sword belt wheel again and in guide rail, do the high speed reciprocating motion.If directionality was poor when the excesssive gap between guide rail and the sword belt, sword belt moved in guide rail, sword head Oscillation Amplitude in motion process is strengthened, cause faults such as staplings, handing-over latitude be bad easily, cause loom production efficiency to reduce.Many looms manufacturing enterprise adopts the fit clearance that reduces guide rail and sword belt usually for reducing this type of fault, though this has reduced the Oscillation Amplitude of sword head in motion process, but the too small meeting in its gap causes the abrasion of guide rail and sword belt too fast, simultaneously manufacturing cost is increased greatly, this problem all exists in import and homemade loom, having had a strong impact on product quality and production efficiency, also is to have a strong impact on the problem that Rapier looms speed promotes.
Pneumato-static slideway is extensive use of in ultra-precision machine tool, but its manufacturing technique of common pneumato-static slideway is all very complicated, causes its cost high, does not see the report that any relevant pneumato-static slideway uses in the loom industry.Application number is that 200710164644.4 utility model patent discloses a kind of recessed pneumato-static slideway, can effectively reduce the guide rail amplitude, but its structure is the structure that has relative motion between the both sides, accuracy of manufacture height, cost is also very high, and is not suitable for the loom industry.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and moves steadily, friction is little, the track-type facilities that is used for loom of low cost of manufacture.
The utility model is achieved through the following technical solutions: a kind of track-type facilities that is used for loom, comprise guide rail and drive the cephalomotor movement parts of sword along the guide rail reciprocating motion, be provided with air cavity in the guide rail, air cavity has a plurality of air outlets, and air outlet is distributed in the below of movement parts.
Described movement parts is the movement parts of sword belt, arrow shaft or other form.
Described air cavity has and is used for the valve that is connected with gas supply mechanism.
Described valve is located at guide rail one side.
Described air cavity is the passage along guide rail, and two ends are provided with the air cavity cover plate of sealing usefulness.
Described air cavity cover plate is fixedlyed connected with the end face of guide rail by screw.
Described air outlet diameter is 0.3～1mm.
The dovetail shaped structure of described guide rail bottom for being used for cooperating with other guide rail.
According to actual needs, the cross section of described air cavity can be designed to various difformities, as square, circle etc.
The track-type facilities that more than is used for loom has utilized the suspension theory of gas; compressed air is caused in the air cavity by valve by gas supply mechanism; owing to have a plurality of air outlets on guide rail and the working face that movement parts cooperates; therefore the compressed air in the air cavity upwards flows through air outlet around the movement spare; movement parts held up to make between movement parts and the guide rail produce the gap; and form the air-flow protection layer around the movement parts and make its motion steadily, thereby reached the purpose that reduces the movement parts vibration, reduces the movement parts wearing and tearing.
The utility model has following advantageous effect with respect to above-mentioned prior art:
1, because the utility model has utilized the suspension theory of gas, make movement parts when reciprocating motion at a high speed, the gas that filling is arranged around the movement parts, itself do not contact with the sword rail, therefore reduced the friction of movement parts greatly, its vibration is reduced greatly, directionality when simultaneously movement parts being moved in guide rail is guaranteed, thereby guaranteed the reliability of handing-over latitude, be beneficial to and improve the loom rotating speed, enhance productivity, prolong the service life of movement parts, reduce production costs, increase economic efficiency.
2, the utility model is to offer air cavity and air outlet etc. on traditional loom track-type facilities, and its manufacturing technique is simple, and manufacturing cost is also low.
