Service HotlineThe assembly of hollow rivets and flat head screws riveted on the cover plate is assembled in the product. Compared with the method of connecting with bolts, the loading and unloading speed can improve the efficiency by about 80% to 90%, and is widely used. The assembly needs to riveted hollow rivets and flat head screws on the cover plate, and ensure that the riveted flat head screws can rotate flexibly. When riveting, it is necessary to use special tools to riveted the hollow rivets, flat head screws and cover plates together for riveting. In the existing riveting process, the oval head screw is often damaged due to the action of external force. The positioning process is cumbersome and the work efficiency is low.
The rod end of the ceramic production equipment is installed with the rod shaft, and then fixed by the cylindrical pin. At present, it is purely manual installation. It is impossible to ensure that the cylindrical pin is kept horizontal during the installation process, and the installation pressure of the cylindrical pin cannot be sensed. The pressure is too large. Cracks in the rollers, too low pressure, and easy loosening of the metal cap; it is impossible to install three or more cylindrical pins at the same time, and it is difficult to align the cylindrical pins with the pin holes of the cylindrical pins, resulting in low efficiency.
Hexagon nuts are also called hexagon nuts. Generally, there are many types of nuts, such as hexagon nuts, round nuts, square nuts and so on. Some standards for nuts are still relatively clear. Some specifications and size standards, material requirements standards, electroplating standards, etc. are relatively clear. Different types of nuts also have different standards. Let's introduce the specifications and standards of the nuts in detail.
The self-tapping locking screw is composed of three parts: the head, the stem and the end of the stem from beginning to end. The composition of each self-tapping screw has four major elements: head shape, wrenching method, thread type, and end type. Head Shapes - Head shapes come in all shapes and sizes. There are round head (semi-round head), oblate head, round head flange (with pad), oblate head flange (with pad), pan head, pan head flange (with pad), countersunk head, semi-countersunk head, Cylinder head, spherical cylinder head, horn head, hexagonal head, hexagonal flange head, hexagonal flange (with gasket), etc. Wrench Styles - There are various ways of wrenching. External wrench: hexagonal, hexagonal flange, hexagonal flange, hexagonal flower shape, etc.; internal wrench: slotted, cross groove H type (Phillips), cross groove Z type (Pozidriv), cross groove F type (Frearson) , Square groove (Scrulox), compound groove, internal spline, internal hexagon flower (plum groove), internal triangle, internal hexagon, internal 12-angle, clutch groove, six-blade groove, high torque cross groove and so on. Thread Types - There are many types of threads. There are self-tapping threads (wide thread), machine threads, drywall screw threads, fiberboard screw threads, and some other special threads. In addition, the thread can be divided into single lead (single head), double lead (double head), multi-lead (multiple head) and high and low thread double head thread. End type - The end type mainly includes saw end and flat end. However, according to the function of use, grooves, grooves, incisions or parts with a cutting function can be processed. In some standards, the same saw end or flat end, there are different forms. There are various changes in the head shape, wrenching method, thread type and shank end type of self-tapping screws. They can be combined with each other to show many different products belonging to the category of self-tapping screws.
In order to achieve the above purpose, Yueluo provides the following technical solutions: threaded rivets include a nail rod, an expansion piece, and a nail sleeve, one end of the nail rod is provided with a mounting piece, and the side of the mounting piece away from the nail rod is movably installed with a mounting piece. There is a driving mechanism. The driving mechanism includes a mounting cylinder and a movable rod. A cross groove is formed at one end of the mounting piece close to the driving mechanism. The rod is movably installed on the inner side of the installation cylinder, and one end of the movable rod close to the cross groove is fixedly provided with a cross connecting piece that matches the cross groove, the cross connecting piece is matched with the cross groove, and the movable rod is far away from the cross groove. One end of the cross connecting piece is fixedly provided with a fixing piece, the fixing piece and the installation cylinder are screwed together by threads, the expansion piece is sleeved on the outer side of the nail rod, and the nail sleeve is movably installed on the nail rod away from the driving mechanism The outer side of one end of the nail rod is movably installed with a fixing mechanism.
