Description

Technical Field

[0001] The utility model relates to the technical field of assembly equipment, in particular to a multi-stud assembly jig. Background Art

[0002] like Figure 1 and Figure 2 The figure shows a heat sink assembly comprising a main plate 1 and a plurality of heat dissipating fins 2 integrally formed and spaced apart from each other. The main plate has three mounting holes arranged in a triangular pattern, within which mounting posts 3 are interference-fitted. The outer ends of the posts are provided with threaded holes for securing the entire heat sink assembly.

[0003] When the radiator component is processed and manufactured as a module, it is necessary to operate the installation column to install it in the assembly hole of the main body plate. Usually, the radiator component is placed on a horizontal support station, and then the three installation columns are placed correspondingly at the three assembly holes on the main body plate. Then, a pressure device is used to drive the pressing plate toward the installation column, and the three pressing rods on the pressing plate respectively press the three installation columns into the assembly holes on the main body plate. The following disadvantages exist in the existing technology: 1. When the installation column is pressed into the assembly hole, the installation column is easily tilted due to the force, resulting in the inability to complete the assembly or the assembly is not in place, affecting the assembly quality and assembly efficiency; 2. When pressure is applied to the installation column, the end face of the installation column is easily damaged. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is how to provide a multi-stud assembly fixture with a simpler and more reasonable structural design, which can better avoid the tilting of the installation column during press-fitting and can better ensure the quality of the rear end surface of the installation column during assembly.

[0005] To achieve the above-mentioned purpose, the utility model provides a multi-stud assembly jig, including a horizontally arranged pressing plate at the upper end; pressing rods are provided on the pressing plates respectively facing the assembly holes on the main plate of the radiator component to be processed; it is characterized in that: a pressing head is connected and fixed to the lower end of the pressing rod, and a vertical mounting hole is provided on the pressing head; a vertical downward vertical rod is provided in the mounting hole, a vertical limiting structure is provided between the vertical rod and the mounting hole and can limit the upper end of the vertical rod from escaping from the lower end of the mounting hole, and a spring thrust structure is also provided between the vertical rod and the mounting hole and can drive the vertical rod to maintain a downward movement trend; the lower end of the vertical rod has a diameter size of at least part of the length section that matches the inner diameter of the threaded hole on the mounting post, and the lower end of the vertical rod is also provided with a magnet block, and the lower end of the vertical rod can be inserted into and fitted in the threaded hole of the mounting post and magnetically connected to the mounting post.

[0006] In this way, when the multi-stud assembly jig is in operation, the mounting post can be manually or mechanically mounted to the lower end of the vertical rod, so that the vertical rod is inserted into the threaded connection hole of the mounting post and magnetically connected to the mounting post.

A threaded fixing hole is provided on the lower end surface of the press rod, and the pressure head connecting block is threadedly connected in the threaded fixing hole.

[0017] In this way, the structural design of the pressure head is simpler and more reasonable, and the pressure head can be replaced more conveniently.

[0018] Furthermore, a spring washer is provided between the upper end surface of the pressing head block and the lower end surface of the pressing rod.

[0019] As an optimization, the pressure head is made of brass.

[0020] In this way, the pressure head is made of brass material, which can protect the upper end surface of the installation column when the installation column is press-fitted.

[0021] As an optimization, a threaded connection hole is provided on the press-fitting plate, and the press-fitting rod is threadedly connected and fitted in the threaded connection hole; and a locking nut is provided at the upper end of the press-fitting rod, and the locking nut is supported against the upper surface of the press-fitting plate.

[0022] In this way, the mounting structure design between the press-fitting rod and the press-fitting plate is more reasonable, and the length of the press-fitting rod can be adjusted more conveniently, thereby better adapting to the press-fitting of the mounting column.
