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 utility model discloses a beating-up rocker shaft device which comprises a beating-up rocker shaft 1, a large balancing weight 2 and a small balancing weight 4. The weight of the big balancing weight 2 is larger than that of the small balancing weight 4. The big balancing weight 2 and the small balancing weight 4 are both connected to the beating-up rocking shaft 1 through screws. The thicknesses of the large balancing weight 2 and the small balancing weight 4 satisfy the following conditions: when the big balancing weight 2 and the small balancing weight 4 swing along with the beating-up rocking shaft 1, the big balancing weight 2 and the small balancing weight 4 can not interfere with the heald frame.
In the utility model, the large balancing weight 2 and the small balancing weight 4 with different weights are included, and the thicknesses of the large balancing weight 2 and the small balancing weight 4 both meet the condition of not interfering with the heald frame, so that the proportioning number of the large balancing weight 2 and the small balancing weight 4 can be set according to the actual requirement, and the positions of the large balancing weight 2 and the small balancing weight 4 can be adjusted randomly along the axial direction of the beating-up rocking shaft 1. Therefore, the gravity center of the beating-up rocker shaft device can be conveniently and accurately adjusted to the center of the beating-up rocker shaft 1. In addition, the convenience of installation of big balancing weight 2 and little balancing weight 4 has been improved to the screw connection.
It should be noted that the center of the beating-up rocker shaft 1 is the midpoint of the axial line of the beating-up rocker shaft 1, and if the center of gravity of the beating-up rocker shaft device is located at the center of the beating-up rocker shaft 1, the beating-up rocker shaft 1 will not swing in the vertical direction nor in the horizontal direction during the swinging process.
It should be noted that, for the sake of convenience of processing, the large weight block 2 and the small weight block 4 are made of the same material, have the same thickness, and only have different lengths. The length of the big balancing weight 2 is longer, and the length of the small balancing weight 4 is shorter.
When the beating-up rocker shaft device is processed and manufactured, an optimal preparation scheme can be debugged through software simulation, and the preparation scheme comprises the proportion of the large balancing weight 2 and the small balancing weight 4 and the positions of the large balancing weight 2 and the small balancing weight 4. The big balancing weight 2 and the small balancing weight 4 are installed according to a preset ratio and a preset position.
In order to ensure the convenience of assembling the large balancing weight 2 and the small balancing weight 4 with the beating-up rocking shaft 1, the large balancing weight 2 and the small balancing weight 4 are provided with grooves matched with the circumferential cambered surface of the beating-up rocking shaft 1, so that the beating-up rocking shaft 1 can be just clamped and matched in the grooves of the large balancing weight 2 and the small balancing weight 4.
As can be seen from the above description: the big balancing weight 2 and the small balancing weight 4 are both connected with the beating-up rocking shaft 1 through screws. The utility model designs a specific screw connection mode: a first screw hole is provided in the large counterweight 2, penetrating through the large counterweight 2, and extending in the radial direction of the beat-up rocker 1. And a first screw 3 matched with the first screw hole firstly penetrates through the first screw hole and then is screwed into the beating-up rocking shaft 1, so that the large balancing weight 2 and the beating-up rocking shaft 1 are locked.
Because the length of big balancing weight 2 is longer, consequently set up two first screw holes on big balancing weight 2, it has a first screw 3 to screw in every first screw hole. So, can ensure the steadiness that big balancing weight 2 and rocking shaft 1 are connected beating up.
In addition, the utility model also arranges a first sinking groove 9 on one side of the big balancing weight 2 back to the beating-up rocking shaft 1, and the first sinking groove 9 is communicated with the first screw hole. The nut of the first screw 3 is sunk in the first sinking groove 9. Because the nut of first screw 3 sinks in first heavy inslot 9, consequently can avoid external spare part and first screw 3 to bump to the fastness of being connected of big balancing weight 2 and beating-up rocking shaft 1 has been ensured.
Because the length of the small balancing weight block 4 is slightly shorter, the small balancing weight block 4 is provided with one second screw hole. The second screw hole penetrates through the small balancing weight 4 and extends along the radial direction of the beating-up rocking shaft 1. And a second screw matched with the second screw hole is inserted into the second screw hole along the radial direction and screwed into the beating-up rocking shaft 1. Thus, the connection between the small balancing weight 4 and the beating-up rocking shaft 1 is realized.
In addition, a second sinking groove is formed in one side, back to the beating-up rocking shaft 1, of the small balancing weight block 4, and the second sinking groove is communicated with a second screw hole. The nut of the second screw is sunk in the second sinking groove. Because the nut of second screw sinks in the heavy inslot of second, consequently can avoid external spare part and second screw to bump to the fastness of being connected of little balancing weight 4 and beating-up rocking shaft 1 has been ensured.
In the present invention, the beat-up rocker 1 is supported by the beat-up rocker 1 holder. The rocker brackets 5 are two or more, and the two or more rocker brackets 5 are arranged symmetrically with respect to the center of the beating-up rocker 1. Therefore, the gravity center of the whole beating-up rocker shaft device is beneficial to being positioned at the center of the beating-up rocker shaft 1. If the number of the rocker brackets 5 is an even number, the rocker brackets 5 are divided into two groups, and the two groups of rocker brackets 5 are symmetrically arranged with respect to the center of the beating-up rocker 1. If the number of the rocker brackets 5 is odd, one rocker bracket 5 is arranged at the center of the beating-up rocker 1, and then the rest rocker brackets 5 are divided into two groups, and the two groups of rocker brackets 5 are symmetrically arranged relative to the center of the beating-up rocker 1.
The utility model also discloses an air jet loom, which comprises a beating-up rocking shaft device, wherein the beating-up rocking shaft device is any one of the beating-up rocking shaft devices, the beating-up rocking shaft device has the advantages, and the air jet loom with the beating-up rocking shaft device also has the advantages, so the details are not repeated.
