DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] like Figure 1 , Figure 2 as well as Figure 5 As shown, an embodiment of the utility model provides a threaded insert loading tool, the loading tool comprising:

[0031] Rack 100;

[0032] A plurality of nut fixing assemblies 200 are fixedly connected to the frame 100, and the nut fixing assemblies 200 include a guide shell 210, a connecting shell 220, and a fixed core rod 230 slidably connected to the guide shell 210 and the connecting shell 220. The guide shell 210 and the connecting shell 220 form a cylindrical shell with a large inner diameter and a small diameter at both ends. The two ends of the fixed core rod 230 are located at the two ends of the cylindrical shell. One end of the fixed core rod 230 is provided with a fixed core rod 230 located at the axis and passing through the The cross groove 232 on the outer wall of the fixed core rod 230, the end of the fixed core rod 230 with the cross groove 232 is provided with a limiting protrusion 233, the limiting protrusion 233 is a gyro shape with a thick middle and small ends, and the end of the fixed core rod 230 with the cross groove 232 is also provided with a limiting sleeve 250, the inner diameter of the limiting sleeve 250 is smaller than the outer diameter of the limiting protrusion 233, and the outer diameter of the limiting sleeve 250 is larger than the inner diameter of the mouth of the cylindrical shell, and the outer diameter of the limiting protrusion 233 is larger than the inner diameter of the nut to be embedded.

[0033] In this embodiment, if Figure 3As shown, when inserting the nut, push the end of the fixed core rod 230 away from the cross groove 232, and pass the nut through the limiting protrusion 233 on the fixed core rod 230. Since the outer diameter of the limiting protrusion 233 is larger than the inner diameter of the nut to be inserted, when the nut is placed on the limiting protrusion 233, the limiting protrusion 233 is compressed, and the nut is sleeved on the fixed core rod 230. Nuts are placed on the fixed core rods 230 on several nut fixing assemblies 200, and then the frame 100 is placed on the workpiece. At this time, the nut is located at the position of the inserting hole, and the frame 100 is pressed. The frame 100 drives the nut fixing assembly 200 to press the nut. Since the nut fixing assembly 200 is fixed on the frame 100, the limiting sleeve 250 on the nut fixing assembly 200 presses the nut into the inserting groove, and the end of the fixed core rod 230 abuts against the bottom of the inserting groove. During the process of the nut being pressed into the setting groove, the bottom of the setting groove pushes the fixed core rod 230 to move in the opposite direction, so that the nut is pushed out from the fixed core rod 230. When the nut is set in the setting groove, the end of the fixed core rod 230 is located on the inner side of the nut, the limiting protrusion 233 is compressed, and the frame 100 is pulled out. Since there is an interference fit between the nut and the setting groove, the friction between the nut and the setting groove fixes the nut in the setting groove, and the fixed core rod 230 is pulled out from the nut. In this way, several nuts can be set at one time. When the nut is placed on the fixed core rod 230, since the limiting protrusion 233 can be compressed, the nut is easily placed on the fixed core rod 230 and then pressed into the setting groove uniformly. In the traditional method of setting one by one, each nut needs to be pressed into the setting groove more laboriously, which saves the setting time and improves the setting efficiency.

[0034] The threaded inlay loading tool disclosed in the embodiment of the utility model is provided with several nut fixing assemblies 200 on a frame 100 to clamp the nuts. During inlaying, several nuts can be inlaid at one time. Compared with the traditional single inlaying method, it can not only improve the inlaying efficiency, but also prevent missing parts and reduce the harm to the staff during inlaying.

[0035] Specifically, in the present embodiment, the frame 100 is a plane or three-dimensional bracket composed of a rod-like structure such as a steel pipe or a metal rod. The shape of the frame 100 is determined based on the position of the nut to be embedded on the workpiece. In the present embodiment, the frame 100 is an I-shaped plane bracket formed by square steel through bolts. The nut fixing assembly 200 is fixed to the two cross arms of the frame 100. There are eight nut fixing assemblies 200, four of which are arranged on each cross arm, so that the present application can install four nuts at one time.
