Description
Technical Field
The utility model belongs to the technical field of the automobile assembling and specifically relates to a welding screw pin of vehicle chassis welding screw thread is related to.
Background
In various industrial settings, threaded pins are used to couple structures together. The utility model relates to a welding screw pin that uses on vehicle chassis. These threaded pins are usually provided with threads only at their ends. During installation, one side end of the threaded pin engages two or more structures to position the parts and maintain their relative positions. The other side end of the threaded pin is screwed into an opening of one of the structures and is partially compressed to form an interference fit with the structure, thereby preventing unnecessary removal of the threaded pin, for example caused by vibration of the structure.
To remove the threaded pin, one common approach is for the operator to screw a threaded tool onto or into the exposed portion of the threaded pin. Once coupled, the threaded pin may be pulled out of the structure, breaking the interference fit. In many instances, the thread structure of the threaded pin wears so severely that it is not reusable, thereby increasing the cost of repair. In addition, the installation of the threaded pin on the chassis adopts an old hand screwing mode, the part mounting and removing efficiency is low, and the requirements of production and daily production are difficult to meet.

Compared with the prior art, the utility model has the advantages of set up the mounting groove to adopt demountable installation screw thread post. The threaded part of the threaded column is worn in the using process, and the threaded column can be quickly disassembled and replaced by a new threaded column. Unlike conventional threaded pin constructions, thread damage requires replacement of the entire threaded pin. The utility model discloses a structure setting has reduced the use cost of screw thread round pin. The bottom of pin pole sets up to polygonal column structure, the artifical hand of adoption when being different from traditional dismouting screw thread round pin is twisted the mode, the utility model discloses a structure setting can adopt the sleeve machine to beat the mode, reduces the cost of labor and improves production efficiency. To sum up, the utility model discloses reduce assembly cost, improve assembly efficiency.

Furthermore, unless specifically stated otherwise, the drawings are merely schematic representations based on conceptual representations of elements or structures depicted and may contain exaggerated displays and are not necessarily drawn to scale.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the exploded structure of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 to 2: the utility model provides a novel welding threaded pin, includes pin rod 1, and mounting groove 2 demountable installation have a screw thread post 3 have been seted up to 1 top surface of pin rod, and the bottom of pin rod 1 sets up to polygonal column structure 4, and the top of column structure 4 links up spacing ring 5, and the diameter of spacing ring 5 is greater than the diameter of pin rod 1.
The threaded column 3 comprises a connecting section 3a inserted into the mounting groove 2 and a threaded section 3b arranged above the pin rod 1, the connecting section 3a is detachably arranged in the mounting groove 2, and the bottom of the connecting section 3a is of a conical structure. The utility model relates to a can dismantle connection including but not limited to threaded connection.
The structure of the mounting groove 2 is adapted to the structure of the connecting section 3 a. The bottom that sets up linkage segment 3a becomes coniform structure, is convenient for be relative with screw thread post 3 and mounting groove 2, to leading-in linkage segment 3a in the mounting groove 2. The bottom of the structure of the mounting groove 2 corresponding to the mounting groove is also set to be conical.
The threaded section 3b is provided with an external thread. Used for realizing the utility model discloses with being connected of other spare parts (for example nut), realize location and fixed on the car chassis.
