[0021] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings:

[0022] Embodiment 1,

[0023] like Figures 1 to 5 As shown, a gear positioning and locking device is used for adjusting, positioning and fixing the gears at different positions in textile machinery and equipment, and specifically includes a box body 1, a gear top block 5, an adjusting bolt 3, a pull plate 4 and a reset spring 7, wherein the box body 1 is hollow inside and open at one end, and an adjusting block thread hole 13 is provided on one side wall of the open end of the box body 1, and an adjusting block 2 is installed at the open end of the box body 1, serving as the end face of the box body 1, and is threadedly fixed and hoisted with the adjusting block 2 by passing a screw 6 through the adjusting block thread hole 13; the adjusting block 2 is provided with ... The whole block 2 is provided with a through hole, and a bushing 21 is fixedly installed inside the through hole. The above-mentioned adjustment bolt 3 passes through the bushing 21 on the adjustment block 2 and extends into the interior of the box body 1. The inner end of the adjustment bolt 3 is rotatably connected to the outer end side of the pull plate 4 through a nut; the cross-section of the pull plate 4 is a U-shaped structure, which is slidably installed inside the box body 1, and the pull plate 4 can be driven to slide by rotating the adjustment bolt 3; at the same time, a reset spring 7 is sleeved on the adjustment bolt 3, and one end of the reset spring 7 is against the outer end side of the pull plate 4 and the other end is against the inner end side of the adjustment block 2. By adjusting the above-mentioned screw 6, the adjustment block 2 can be driven to move up and down, and the installation height of the adjustment bolt 3 can be adjusted, thereby ensuring the concentricity of the adjustment bolt 3 and the pull plate 4; the existence of the above-mentioned bushing 21 can also reduce the friction coefficient between the adjustment bolt 3 and the adjustment block 2.

[0024] A gear top block guide groove 11 is provided on one of the side walls of the above-mentioned box body 1, and the gear top block 5 is adapted to be slidably installed in the gear top block guide groove 11 and is placed between the two side walls of the above-mentioned U-shaped pull plate 4; two side walls adjacent to the gear top block guide groove 11 on the box body 1 are also provided with two symmetrical vertical pulley pin guide grooves 12, and correspondingly, inclined sliding guide grooves 41 are symmetrically provided on the two side walls of the above-mentioned pull plate 4, and the sliding guide groove 41 is lower on the side close to the opening end of the box body and higher on the side away from the opening end of the box body, and its lowest end is coaxially arranged with the lowest end of the above-mentioned pulley pin guide groove 12. The lower end of the above-mentioned gear top block 5 is detachably inserted with a transverse pulley pin 52, which can be extended from the sliding guide groove 41 on the pull plate 4 and the pulley pin guide groove 12 on the box body 1 in turn and slidably installed there along, so that the gear top block 5 can be lifted and lowered; the top of the gear top block 5 is provided with a locking tooth shape 51, which is used to mesh and lock the target gear. The locking tooth shape 51 can be selected from standard rack teeth or involute splines, and its inclination angle is determined according to the target gear, so that a variety of different specifications can be provided to adjust and replace gears according to different angles, so as to adapt to the positioning and locking of target gears at different installation positions, thereby improving its versatility.

[0025] When used specifically, Figure 6 Taking the structure shown as an example, the target gear shown in the figure is an integrated structure of cam 100-gear 9-locking sleeve 101. The traditional installation method is: first adjust the device to the angle where the rocker 102 is at the highest point, then rotate the gear 9 until the rocker 102 is at the highest point, and then tighten the locking sleeve 101; the above installation process has the following problems: First, the highest point position of the cam 100 will have an angle error, and when the rocker 102 is rotated a small amount to the left or right at the highest point, the rocker 102 will not have a visible displacement; second, when tightening the locking sleeve 101, since the cam 100 is in force balance at the highest point, it will be subjected to radial force from the bolt during the process of tightening the locking sleeve 101. At this time, the gear 9 will rotate a small amount, and even cause the cam 100 to be directly squeezed out and out of the highest point.

[0026] When using the above device of the present invention, first place the box body 1 under the target gear 9, determine the target tooth to be fixed, and take the tooth facing the opening of the lock sleeve 101 as the target tooth; then rotate the adjustment bolt 3 to drive the pull plate 4 to move outward, and due to the cooperation of the inclined sliding guide groove 41 and the vertical pulley pin guide groove 12, the gear top block 5 is driven to rise upward, and the locking tooth shape 51 at its upper end is meshed and bitten with the target gear 9 to form a positioning fixation; then tighten the lock sleeve 101. When the tightening is completed, rotate and loosen the adjustment bolt 3, and under the elastic force of the reset spring 7, the pull plate 4 is pushed inward to reset, and the gear top block 5 is lowered and recovered, disengaged from the loosened target gear 9, and the positioning installation is completed.

[0027] When the tooth shape of the target gear 9 does not match the locking tooth shape 51 on the gear top block 5, the gear top block 5 can be replaced by pulling out the pulley pin 52. The replacement is simple and can be adapted to the positioning and installation of different gears at multiple different workstations.

[0028] Embodiment 2,

[0029] A gear positioning and locking device, whose overall structural features are roughly similar to the technical solution described in the above-mentioned embodiment 1, includes a box body 1, a gear top block 5, a pull plate 4, an adjustment bolt 3 and a reset spring. The difference between the two is that: the lower end of the gear top block 5 is provided with mutually symmetrical sliding cavities on both sides, and the pulley pin 52 is slidably installed in the sliding cavity on the corresponding side and forms a limited sliding with it to prevent it from popping out of the sliding cavity; a telescopic spring is installed between the pulley pin 52 and the inside of the sliding cavity, so that the pulley pin 52 can perform a telescopic action relative to the gear top block 5, and can be detachably slidably assembled with the sliding guide groove 41 on the above-mentioned pull plate 4 and the pulley pin guide groove 12 on the box body 1, so as to facilitate the replacement of the gear top block 5.

[0030] The length of the pulley pin guide groove 12 on the box body 1 and the inclination angle of the sliding guide groove 41 on the pull plate 4 can also be independently set according to the needs in actual operation to change the movement trajectory and rising height of the gear top block 5 to suit the installation of gears at different workstations.

[0031] 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.
