[0017] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings:

[0018] like Figure 1 to Figure 2 As shown, a heald frame positioning and installation device includes a main frame 1, a power and guide component, and a positioning component, wherein the main frame 1 is the supporting base of the entire device, and is assembled and fixed with aluminum alloy plates, and connecting plates 11 are fixedly installed on both sides thereof, which ensure the stability of the frame structure while reducing the weight of the entire device. The connecting plates 11 can also serve as the handle of the entire device, which is convenient for the installer to carry and use. The power and guide assembly includes a jack 2, a jack top plate 3, a guide shaft 4 and a heald frame top plate 6, wherein the jack 2 uses a double-section jack, which is fixedly installed at the center position of the side wall of the bottom plate of the main frame 1. The double-section jack can increase the travel range and is suitable for positioning and installing all specifications of heald frames 14 under different specifications of pull rods 13 and different height process standards; the top of the top rod in the jack 2 is fixedly installed with a horizontally arranged jack top plate 3, and the upper surface of the jack top plate 3 is fixedly installed with four vertically installed guide shafts 4, which are located at its four corners and parallel to each other; the four guide shafts 4 all pass through the top plate 12 in the main frame 1 upward and extend upward, and the heald frame top plate 6 is fixedly installed at the top thereof, and the heald frame top plate 6 is parallel to the jack top plate 3 to ensure that all heald frames rise synchronously and horizontally, and the setting width is based on the sixteen heald frames of the multi-arm machine, so that it can be suitable for the adjustment of the heald frames of all crank looms and cam looms. A linear bearing 5 is fixedly installed between the guide shaft 4 and the top plate 12 of the main frame 1. The guide shaft 4 and the corresponding linear bearing 5 slide relative to each other, thereby ensuring the verticality of the guide shaft 4 and extending its service life. A return spring 10 is also mounted on each guide shaft 4, one end of which is against the upper end surface of the jack top plate 3 and the other end is against the bottom of the linear bearing 5 upward.

[0019] The above-mentioned positioning assembly is installed between the jack top plate 3 and the heald frame top plate 6, and includes a positioning rod 7, a positioning plate 8 and a locking sleeve 9, wherein the positioning rod 7 also passes through the top plate 12 of the main frame 1 through the linear bearing 5, and its upper and lower ends are respectively fixedly connected to the center of the heald frame top plate 6 and the jack top plate 3, and are parallel to the above-mentioned guide shaft 4; the positioning plate 8 and the locking sleeve 9 are sequentially mounted on the positioning rod 7, located below the above-mentioned linear bearing 5, and the locking sleeve 9 is placed below the positioning plate 8, and the two ends of the positioning plate 8 are also slidably connected to the inner side walls of the two vertical plates of the main frame 1 to ensure its stability.

[0020] The specific usage principle is as follows: Figure 3As shown, taking the positioning and installation of a piece of heald frame 14 as an example, first turn the air jet loom to the flat heald position, place the overall heald frame positioning and installation device between the tie rod 13 and the bottom surface of the heald frame 14, and hold one piece in each hand. Since the heald frame tie rod 13 is used as the bottom surface, its horizontality can be well guaranteed. Then the jack 2 runs and pushes upward, driving the jack top plate 3 to move upward, and then drives the heald frame top plate 6 to move upward through the guide shaft 4. It can rise or stop at any time, and the height is measured when it stops. When the required heald frame installation height is reached, it stops rising, and the installer performs fixed installation of the heald frame 14. After the installation is completed, if this loom is the first one to be installed in the same batch, the locking sleeve 9 can be slid to the bottom of the positioning plate 8, so that the upper end surface of the positioning plate 8 contacts the lower end of the linear bearing 5 and is fixed in place, marking the installation and lifting height of the heald frame 14; when installing the heald frame of the next loom, it is only necessary to raise the height of the heald frame 14 to the point where the locking sleeve 9, the positioning plate 8 and the linear bearing 5 are in contact, and there is no need to measure the height one by one, so as to improve the installation efficiency and save time and effort. After all the installation is completed, release the oil return valve of the jack 2. At this time, the heald frame top plate 6, the guide shaft 4 and the jack top plate 3 are reset under the action of their own gravity and the reset spring 10, completing the installation task.

[0021] Furthermore, the guide shafts 4 are all subjected to rust-proof treatment on their surfaces, so that they have high straightness and smoothness, and can more easily transmit the lifting force of the jack 2.

[0022] The positioning plate 8 can also be fixedly installed inside the main frame 1, and the positioning of the installation and lifting height of the heald frame 14 is completed through the contact limit between the positioning plate 8 and the locking sleeve 9.

[0023] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
