Detailed Description
The present invention will now be described in more detail with reference to the drawings, in which preferred embodiments of the invention are shown, it being understood that one skilled in the art could modify the invention herein described while still achieving the beneficial effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
As shown in FIGS. 5 to 11, the present invention discloses a positioning structure for a welding nut (hereinafter referred to as "the positioning structure"), which comprises a nut positioning rod 1, wherein a connecting part 1a connected with a cylinder is arranged at the top of the nut positioning rod, the connecting part is an axially outer threaded rod arranged at the top of the nut positioning rod, the nut positioning rod is connected with a movable cylinder by screw threads, the nut positioning rod can be replaced at will and is convenient to produce, the nut positioning rod is provided with a cylindrical rod body, a welding nut leading-in structure is arranged near the bottom 1b of the cylindrical rod body, the welding nut leading-in structure is a reducing structure arranged at the bottom of the cylindrical rod body, the reducing structure is gradually reduced from the cylindrical rod body towards the bottom end of the cylindrical rod body, the lower part of the cylindrical rod body is provided with an opening 2 extending from the bottom end of, and tensioning parts 1c for tensioning the welded nut are arranged on two sides of the opening.
It can be seen from the above that, the positioning structure for the weld nut can fix the weld nut by the ability of the tensioning portion to deform to a certain extent, and the diameter of the portion of the cylindrical rod body for mounting the weld nut is 0.5mm larger than that of the weld nut, so that the tensioning portion of the cylindrical rod body deforms towards the opening direction under the condition that the weld nut 4 (projection weld nut) is sleeved in, and the tensioning portion has the ability of resisting deformation and expanding outwards, so that the weld nut can be stably mounted on the nut positioning rod.
Referring to fig. 6-9, the cylindrical shaft is provided with symmetrically arranged concave surfaces 3, the concave surfaces 3 can be used for limiting a wrench, and the mechanism is fixed by threads and is movable, so that the mechanism (the nut positioning rod) can rotate after the wrench is fixed at the concave surface 3.
The nut positioning rod is made of nonmagnetic spring stainless steel.
Fig. 1-4 are diagrams showing the effect of the positioning structure mounted on the welding equipment, and the drawings show a movable cylinder 5 for fixing the nut positioning rod 1, an upper electrode rod 6 mounted on the telescopic rod where the movable cylinder 5 is located, and an electrode connecting rod 7 disposed at the lower part of the upper electrode rod.
The working principle of the utility model is as follows: the locating lever links to each other with the cylinder, and the locating lever utilizes the front end tight portion that rises to fix a position the nut, prevents that the nut from dropping. When a projection welding instruction is given, the air cylinder presses downwards, the positioning rod drives the nut to the upper surface of a part below, then the electrode connecting rod contacts the nut, and then discharge is carried out to complete the whole projection welding work.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
