Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0017] The specific embodiments of the utility model will be explained in further detail below with reference to the drawings:

[0018] As Figures 1 to 2 shown, a harness frame positioning installation device, including main body frame 1, power and guide assembly, positioning assembly, wherein main body frame 1 is the support basis of entire device, adopt aluminium alloy sheet assembly fixed and become, its two side edges still fixedly installed with connecting plate 11, ensure that frame structure is stable while lightens the weight of overall device, connecting plate 11 can also act as the handle of entire device, be convenient for installation personnel to carry and use. Power and guide assembly includes jack 2, jack top plate 3, guide shaft 4 and harness frame top plate 6, wherein jack 2 selects double-section jack, is fixedly installed on the bottom plate upper side wall center position of main body frame 1, and double-section jack can increase the range of travel, is suitable for the positioning installation of harness frame 14 of all specifications under different specifications of pull rod 13 and different height process standards. The top end of the top rod in jack 2 is fixedly installed with horizontally arranged jack top plate 3, the upper surface of jack top plate 3 is fixedly installed with four vertical installation guide shafts 4, which are located at the four corners and parallel to each other. Four guide shafts 4 all pass through the top plate 12 of main body frame 1 upwards and extend upwards, and the top ends of the guide shafts 4 are fixedly installed with harness frame top plate 6. The harness frame top plate 6 is parallel to the jack top plate 3 to ensure that all harness frames are raised synchronously and horizontally. The width of the harness frame top plate 6 is set based on the sixteen harness frames of a dobby machine, so that it can be suitable for the harness frame adjustment of all crank looms and cam looms. Linear bearings 5 are fixedly installed between the guide shafts 4 and the top plate 12 of the main body frame 1. The guide shafts 4 and the corresponding linear bearings 5 slide relative to each other to ensure the perpendicularity of the guide shafts 4 and prolong their service life. Each of the guide shafts 4 is also sleeved with a return spring 10. One end of the return spring 10 abuts against the upper end surface of the jack top plate 3, and the other end abuts against the bottom of the linear bearing 5 upwards.

[0019] The positioning assembly is installed between the jack top plate 3 and the harness frame top plate 6 and includes a positioning rod 7, a positioning plate 8, and a locking sleeve 9. The positioning rod 7 also penetrates the top plate 12 of the main body frame 1 through a linear bearing 5. The upper and lower ends of the positioning rod 7 are fixedly connected to the center of the harness frame top plate 6 and the jack top plate 3, respectively, and are parallel to the guide shafts 4. The positioning plate 8 and the locking sleeve 9 are sequentially sleeved on the positioning rod 7 and are located below the linear bearing 5. The locking sleeve 9 is located below the positioning plate 8. 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 body frame 1 to ensure the stability thereof.

[0020] The specific use principle is as follows: refer to Figure 3As shown, taking the positioning and installation of a heald frame 14 as an example, the air jet loom is first turned to the leveling position. The overall heald frame positioning and installation device is placed between the tie rod 13 and the bottom surface of the heald frame 14, with one held in each hand. Since the heald frame tie rod 13 serves as the bottom surface, its levelness is well ensured. The jack 2 then operates and pushes upward, driving the jack top plate 3 upward. This is transmitted through the guide shaft 4, and in turn drives the heald frame top plate 6 upward. The jack can be raised or stopped at any time, and the height is measured when it stops. When the heald frame reaches the required installation height, the jack stops rising, and the installer then secures the heald frame 14. After installation is complete, if this loom is the first 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 tightened in place, marking the installation 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 until the locking sleeve 9, positioning plate 8 and linear bearing 5 are in contact. There is no need to measure the height one by one, which improves installation efficiency and saves time and effort. After all installation is completed, release the oil return valve of the jack 2. At this time, the heald frame top plate 6, guide shaft 4 and 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 scope of protection of the present invention.
