[0002] At present, the thread twisting tooth is designed according to the size of the crank gear, and the angle of the crank gear is designed according to the size of the pressure plate. The existing screw or lead screw transmission structure drives the pressure plate or screw every time. Accurate positioning cannot be performed even by rotation, and the positioning of the pressure plate can only be achieved by stepping motors or limit switches. Although these two methods can achieve better positioning results, there is a problem of high cost, not only the purchase cost of parts High, which is also reflected in the labor cost of equipment debugging. Additional control systems need to be added, and software needs to be purchased, which adds a lot of expenses to the enterprise. screw stop device

The invention relates to a thread stop device, which comprises an elastic reset positioning assembly, a driving shaft, a screw and a threaded sleeve screwed with the screw; the driving shaft is provided with a main transmission part, and the screw is provided with a main The driven part matched with the transmission part, the driven part is coaxially rotatable with the screw rod; the screw rod is provided with at least one limit slot that cooperates with the elastic reset positioning assembly, and the elastic reset positioning assembly is inserted into the limit slot through reset. The stop positioning of the follower is realized in the position groove. Compared with the existing technology, this device does not need to be positioned by parts such as stepping motors and limit switches, which saves the cost of parts, has a simple structure, low manufacturing cost, and does not need a control system. There is no need for debugging during installation, the assembly time is short, and the maintenance difficulty is low.
Description
technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a thread stop device. Background technique [0002] At present, the thread twisting tooth is designed according to the size of the crank gear, and the angle of the crank gear is designed according to the size of the pressure plate. The existing screw or lead screw transmission structure drives the pressure plate or screw every time. Accurate positioning cannot be performed even by rotation, and the positioning of the pressure plate can only be achieved by stepping motors or limit switches. Although these two methods can achieve better positioning results, there is a problem of high cost, not only the purchase cost of parts High, which is also reflected in the labor cost of equipment debugging. Additional control systems need to be added, and software needs to be purchased, which adds a lot of expenses to the enterprise. screw stop device. Contents of the inven...
