Detailed Description
The utility model discloses a heald frame connecting device which can simplify the replacing steps of a connecting rod and improve the replacing efficiency of the connecting rod. The utility model also discloses a loom.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The heald frame connecting device in the present invention comprises a driving assembly and a connecting rod 5. The driving assembly comprises a clamping seat 1, and the clamping seat 1 is a power output end of the driving assembly. The driving component outputs the power of up-and-down motion through the clamping seat 1. The cartridge 1 has cartridge holes arranged in a horizontal direction. In the horizontal direction, one end of the holder hole is a closed end 3, and the other end is an open end. The clamping seat 1 comprises a torsion spring, and a torsion bar 2 of the torsion spring extends into the clamping seat hole along the vertical direction.
The lower end of the connecting rod 5 is provided with a fixture block 4, and the fixture block 4 can pass through the opening end of the fixture seat hole and overcome the resistance of the torsion bar 2 to enter between the torsion bar 2 and the closed end 3. After the fixture block 4 enters between the closed end 3 and the torsion bar 2, the torsion bar 2 is reset, and the horizontal state is reset to the vertical state. The torsion bar 2 can prevent the movement of the link 5 towards the open end of the cartridge hole. The upper end face and the lower end face of the clamping seat hole are respectively used for clamping the upper end face and the lower end face of the clamping block 4, so that the connecting rod 5 is clamped with the clamping seat 1. When the clamping seat 1 moves upwards, the lower end face of the clamping seat hole can push the clamping block 4 to move upwards, so that the connecting rod 5 and the heald frame 11 are driven to move upwards. When the clamping seat 1 moves downwards, the upper end surface of the clamping seat hole can push the clamping block 4 to move downwards, so that the connecting rod 5 and the heald frame 11 are driven to move downwards.
In the utility model, when the driving component and the connecting rod 5 are assembled, the connecting rod 5 is directly pushed towards the closed end 3 of the clamping seat hole, the clamping block 4 is enabled to extrude the torsion bar 2 towards the closed end 3, so that the clamping block 4 passes over the torsion bar 2, and after the clamping block 4 passes over the torsion bar 2, the torsion bar 2 is reset, and the clamping block 4 is blocked. When the connecting rod 5 needs to be replaced, the torsion bar 2 is extruded through external force, so that the torsion bar 2 is in a horizontal state, and then the clamping block 4 can be separated from the clamping seat hole. Compared with the technical scheme that the connecting rod and the driving assembly are fastened through the screws in the prior art, the arrangement of the torsion spring and the clamping seat 1 can obviously simplify the replacing step of the connecting rod 5 and improve the replacing efficiency of the connecting rod 5.
The following detailed description will be directed to the specific structure of the cartridge 1: the clamping seat 1 comprises a clamping plate 6, and clamping holes arranged in the horizontal direction are formed in the clamping plate 6. In the horizontal direction, one end of the clamping hole is a closed end, and the other end of the clamping hole is an open structure. The cardboard 6 is two, and two cardboard 6 parallel arrangement. The two card holes of the two card plates 6 form the above-described card seat holes. A gap is formed between the two catch plates 6, which gap serves to accommodate the connecting rod 5. When the clamping block 4 is pushed towards the closed end 3, the connecting rod 5 connected with the clamping block 4 can enter the gap between the two clamping plates 6.
It should be noted that the connection mode of the fixture block 4 and the connecting rod 5 is screw locking. The lower part of the connecting rod 5 is provided with a reducing head part, the diameter locking head part is provided with external threads, and the fixture block 4 is screwed on the reducing head part and is tightly backed on the junction end surface of the connecting rod 5 and the reducing head part.
A torsion spring is mounted between the two catch plates 6. In the natural state, the torsion bar 2 of the torsion spring is erected in the two catch holes and in the gap of the two catch plates 6.
The latch 4 has a cylindrical shape. The side of the heald frame 11 is provided with a rod hole in which the connecting rod 5 is screw-fitted. The upper part of the connecting rod 5 extends out of the rod hole. If it is desired to adjust the height of the heald frame 11, the heald frame 11 can be moved by turning the upper part of the connecting rod 5. When the connecting rod 5 rotates towards one direction, the heald frame 11 moves upwards; when the connecting rod 5 is rotated in the other direction, the heald frame 11 moves downward. In this way, the height of the heald frame 11 can be adjusted at the upper part of the heald frame 11 without having to reach under the heald frame 11 to adjust the height of the heald frame 11.
It should be noted that, because the structure of the latch 4 is a cylinder, the latch 4 can rotate around its own axis in the socket hole. When the connecting rod 5 is rotated, the fixture block 4 can be self-transmitted in the fixture seat hole.
It should be noted that, because the connecting rod 5 and the heald frame 11 are in threaded connection in the present invention, the connecting rod 5 will not be randomly pulled out from the heald frame 11 when the heald frame 11 is disassembled and replaced, thereby facilitating the disassembly and replacement of the heald frame 11.
In order to facilitate the screwing of the connecting rod 5, the present invention provides a shaft tube 10 at an upper portion of the connecting rod 5. The section of the shaft tube 10 is a hexagonal shape. In this way, it is facilitated to screw the shaft tube 10 with the aid of a tool while rotating the connecting rod 5.
In order to ensure that the heald frame 11 can stably move up and down along with the connecting rod 5, the utility model is additionally provided with a locking nut 9. The locknut 9 is screwed onto the upper part of the connecting rod 5, the locknut 9 tightening the connecting rod 5 against the side of the heald frame 11. In order to prevent the lock nut 9 from causing pressure loss to the side portion of the heald frame 11, the present invention provides a spacer between the lock nut 9 and the side portion of the heald frame 11.
In order to avoid the abrasion between the connecting rod 5 and the inner wall of the rod hole, the utility model is designed as follows: the upper part in the rod hole is nested with a threaded sleeve 8, the connecting rod 5 is in threaded fit in the threaded sleeve 8, and the threaded sleeve 8 is fixedly connected with the side part of the heald frame 11. The connecting rod 5 is screwed to the side of the heddle frame 11 by means of a threaded bushing 8. Since the connecting rod 5 is in direct contact with the threaded sleeve 8, abrasion between the connecting rod 5 and the threaded sleeve 8 occurs during screwing of the connecting rod 5, and does not directly abrade the inner wall of the rod hole.
Further, the present invention also nests an inner bushing 7 at the lower portion inside the rod bore. The link 5 penetrates the inner bush 7 and is movable up and down with respect to the inner bush 7. In this way, the upper part of the connecting rod 5 is engaged with the threaded sleeve 8, and the lower part of the connecting rod 5 is engaged with the inner bushing 7, so that the connecting rod 5 does not contact the inner wall of the rod hole. In this way, the abrasion of the rod hole inner wall by the connecting rod 5 is further prevented.
Next, a drive assembly is described, which comprises, in addition to the cassette 1, an angle-shaped lifting heddle arm 13, a short link 12, a drive rod 14. The angle-shaped heald lifting arm 13 is in an angle shape, and the angle part of the angle-shaped heald lifting arm 13 is hinged on the fixed pin shaft. The output end of the driving rod 14 is hinged at one end of the angle type heald lifting arm 13, and the driving rod 14 is used for driving the angle type heald lifting arm 13 to swing around the fixed pin shaft. The other end of the angle type lifting heald arm 13 is hinged with the lower end of the short connecting rod 12, and the upper end of the short connecting rod 12 is hinged on the clamping seat 1.
In the prior art, a short connecting rod is not arranged, and the lower end of the connecting rod is directly connected to the angle type heald lifting arm. However, the angle-type lifting arm has displacement not only in the vertical direction but also in the horizontal direction during swinging, so that the connecting rod and the heald frame are driven to generate displacement in the horizontal direction, and the displacement in the horizontal direction has negative influence on the operation of the heald frame. In order to eliminate the displacement in the horizontal direction, the utility model is additionally provided with a short connecting rod 12, one end of the short connecting rod 12 is hinged on the clamping seat 1, and the other end is hinged on the angle type heald lifting arm 13. The horizontal displacement of the angle type heald lifting arm 13 generated in the swinging process can be released by the short connecting rod 12 in a rotating mode, the vertical displacement of the angle type heald lifting arm 13 generated in the swinging process can be transmitted to the clamping seat 1 through the short connecting rod 12, and then the clamping seat 1 drives the connecting rod 5 and the heald frame 11 to move in the vertical direction.
It should be noted that the heald frame 11 has a left side portion and a right side portion, each side portion is provided with a rod hole, each rod hole is internally provided with a connecting rod 5, and each connecting rod 5 is clamped with one clamping seat 1 through one clamping block 4. A short connecting rod 12 is hinged below each clamping seat 1, the lower part of each short connecting rod 12 is hinged on an angle-shaped heald lifting arm 13, and the two angle-shaped heald lifting arms 13 are connected through an intermediate rod 15. In this way, when the driving rod 14 drives one angle-shaped heald lifting arm 13 to swing, the angle-shaped heald lifting arm 13 drives the other angle-shaped heald lifting arm 13 to swing synchronously through the intermediate rod 15, so that the two sides of the heald frame 11 move up and down synchronously.
The utility model also discloses a loom, which comprises a heald frame connecting device, wherein the heald frame connecting device is any heald frame connecting device. The heald frame connecting device has the above effects, and a loom having the heald frame connecting device also has the above effects, and therefore, the details are not repeated herein.
