DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] like Figure 1-3 As shown, the accumulation wire spring adjustment tool 100 in one embodiment of the present invention includes a bracket 10, an adjustment mechanism and a positioning mechanism 30. The adjustment mechanism includes a fixed fork arm 21 and an adjustment fork arm 22 for clamping the accumulation wire spring, the fixed fork arm 21 is fixed to one end of the bracket 10, and the adjustment fork arm 22 is movably installed on the bracket 10, and can move away from or close to the fixed fork arm 21. The positioning mechanism 30 is installed on the bracket 10, including a limiter 32 protruding to the moving path of the adjustment fork arm 22, and the limiter 32 is used to block the adjustment fork arm 22 when it moves in the direction of the fixed fork arm 21.

[0025] like Figure 3 As shown, in actual use, the adjustment fork arm 22 can be first moved to the farthest distance from the fixed fork arm 21, and then the accumulation line spring adjustment tool 100 can be moved to the spring that needs to be adjusted. After placing the fixed fork arm 21 at one end of the gear and the adjustment fork arm 22 at the spring at the other end, move the adjustment fork arm 22 toward the fixed fork arm 21, compress the accumulation line spring until it is adjusted to the target accumulation force, and then move the limiter 32 to abut against the adjustment fork arm 22. This position is the spring position corresponding to the target accumulation force. In the subsequent adjustment process of other springs, it is only necessary to move the adjustment fork arm 22 to abut against the limiter 32, thereby shortening the adjustment time and improving work efficiency and consistency of adjustment.

[0026] like Figure 1 As shown, the adjustment mechanism further includes a guide rail 23 and a first slider 24 that moves on the guide rail 23. The guide rail 23 is perpendicular to the fixed fork arm 21, and the adjustment fork arm 22 is moved by fixing it on the first slider 24. An adapter plate 25 is also fixed on the first slider 24, and the first slider 24 is fixed on the adapter plate 25 to fix the first slider 24.

[0027] Preferably, the adapter plate 25 includes a main body 251 fixed to the first slider 24, and an extension arm 251 extending in a direction perpendicular to the guide rail 11, and the adjustment fork arm 22 is fixed to the extension arm 251. Since the adapter plate 25 is also designed in two sections, there is a blank area between the main body 251 and the extension arm 252, so it will not interfere with the spring or the bevel gear during operation.

[0028] In one embodiment, the bracket 10 is provided with a guide groove 11 perpendicular to the fixed fork arm 21, and the positioning mechanism 30 further includes a second slider 31 moving on the guide groove 11, and a limiter 32 is fixed on the second slider 31. The position of the limiter 32 is adjusted by moving the second slider 31, so as to determine the spring compression distance corresponding to the target accumulation force.

[0029] like Figure 1 As shown, a first mounting hole 311 is provided on the second slider 31, and the stopper 32 can be in the form of a plunger, which is pluggable and installed in the first mounting hole 311. Pressing the plunger can make one end of the plunger protrude to the moving path of the adjustment fork arm 22, or pulling it backwards so that one end of the plunger is immersed in the first mounting hole 311. At this time, there is no obstruction on the moving path of the adjustment fork arm 22, and it can be freely moved and adjusted, with higher flexibility.

[0030] A limiting groove 313 is also provided on the second slider 31, which extends in a direction perpendicular to the fixed fork arm 21, and a portion of the adjusting fork arm 22 extends into the limiting groove 313. When the adjusting fork arm 22 moves in the limiting groove 313, it is blocked by the side walls at both ends thereof, resulting in the movement range being limited by the limiting groove 313 when the plunger is not exposed, thereby avoiding the situation where the adjusting fork arm 22 moves excessively due to improper operation during the adjustment process, so as to further improve stability.

[0031] like Figure 1 As shown, the second slider 31 is also provided with a second mounting hole 312, which is connected to the guide groove 11. The guide groove 11 is designed in two sections in the axial direction of the second mounting hole 312, including a first section 111 close to the second mounting hole 312 and a second section 112 away from the second mounting hole 312, and the width of the second section 112 is greater than the first section 111. Through such a design, the second slider 31 can be fixed on the bracket 10 by a fixing bolt and a fixing nut (not shown), that is, the fixing nut is placed in the second section 112, and the fixing bolt is inserted into the fixing nut after passing through the second mounting hole 312. Since the guide groove 11 is in a posture of being small at the top and large at the bottom in the axial direction of the second mounting hole 312, the fixing nut cannot be separated from the guide groove 11 in this direction. The second slider 31 can be moved after loosening the fixing bolt and the fixing nut, and the second slider 31 can be fixed at the appropriate position by tightening the fixing bolt and the fixing nut after moving to the appropriate position.

[0032] Preferably, second mounting holes 312 are provided at both ends of the second slider 31 in the moving direction, so as to fix the second slider 31 from both ends, thereby achieving higher stability.

[0033] It can be imagined that, since the second sliding block 31 is movable, the moving range of the adjustment fork arm 22 is correspondingly increased, and the flexibility is higher.

[0034] In order to increase the contact area with both ends of the spring, the ends of the fixed fork arm 21 and the adjustable fork arm 22 are designed to be open, that is, Figure 1 The arc-shaped opening 26 shown in the figure, so during operation, the accumulation wire spring adjustment tool 100 can be moved to accommodate the connecting rod of the sleeve spring in the arc-shaped opening 26. At this time, the spring abuts against the entire outer side wall of the arc-shaped opening 26, so that the contact area with both ends of the spring can reach nearly 75% of its total area, so that the spring can be compressed more stably and the stability is higher.

[0035] In other embodiments, a lead screw drive can be used to drive the adjustment fork arm 22 to move, so as to improve the precision of the accumulation force adjustment. Specifically, a lead screw can be installed on the guide rail 23, a through screw hole is opened on the first slider 24, the lead screw is inserted into the screw hole, and the first slider 24 and the adjustment fork arm 22 are driven to move by rotating the lead screw under the meshing of the thread. Such a design can make the movement process of the adjustment fork arm 22 more linear, without abrupt movement, and the entire movement process is more delicate, with higher control accuracy, and the accumulation force can be quickly adjusted to the best.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
