Service HotlineGuangdong Yueluo Hardware Industry Co., Ltd. relates to a connecting piece, especially a wood screw used for fixing on non-rigid materials such as wood or plastic. Guangdong Yueluo Hardware Industry Co., Ltd. has a threaded part with a taper angle and a screw head. The head of the screw can be countersunk, hemispherical, or other shapes. As for the grooves for screwing, the grooves can be straight-line grooves, concave cross grooves, or grooves of other shapes.
Countersunk head screw, also called countersunk head screw, also known as flat machine screw, is a kind of construction part. The head is a 90-degree cone, similar to common wood screws. The head has tool tightening grooves, such as a zigzag, cross, inner hexagon, plum blossom, pentagon, etc. Screws are all connectors used to connect two objects. Generally, the head of the screw will protrude above the surface of the object to be connected, so that the surface will lose its smoothness. Countersunk head screws can be sunk under the surface to make the surface flat. For hard objects, countersunk holes need to be drilled in the corresponding positions of the countersunk head. In short, the countersunk head is the head of the screw that can keep the surface flat after installation.
Pin riveting is an important procedure in the production process. At first, people used manual work, which has low production efficiency, high production cost, and high defect rate of products produced. Later, a pin riveting machine appeared. The pin riveting machine is a For riveting and pinning of hardware products, the pin riveting machine can complete the operation of pin loading and riveting pins, and the pin riveting machine reduces the process of pin loading and riveting pins in the hardware production process. However, its structural design is unreasonable and the operation is very inconvenient
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a bayonet which is a T-shaped cylindrical pin with a misaligned through hole at the head, and a bayonet spring which is a ring-shaped spring steel wire whose ends are staggered. The retaining ring is clamped by the bayonet pin to fix the stop sleeve and the pin shaft together. A hydraulic excavator pin stopper with high disassembly and assembly efficiency and no need for a wrench. The technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is such that it includes a latch, a stop sleeve, a pin, a bayonet, and a circlip. The staggered end is clamped into the misaligned through hole of the plug, and screwed on the bottom of the stopper sleeve to fix the stopper sleeve and the pin shaft together. The latch is composed of a bayonet pin and a circlip, the circlip is screwed around the through hole of the bayonet pin to the root of the bayonet pin, and the stopper sleeve is tightly wrapped around the pin shaft, and the circlip is tightly against the bayonet pin. The head of the bayonet pin has two T-shaped cylindrical pins with staggered through holes, and the circlip is an annular spring steel wire whose ends are staggered. By adopting the pin shaft stopping method of the above technical scheme, it is extremely convenient and quick to disassemble and assemble the pin shaft. The bolt of Guangdong Yueluo Hardware Industry Co., Ltd. is only composed of a T-shaped cylindrical pin with two staggered through holes in the head and a ring-shaped spring steel wire with staggered ends. The structure is simple, convenient to manufacture, low cost and obvious. It is an excavator pin stop method with high disassembly and assembly efficiency, no need for a wrench and low manufacturing cost.
Locating pins are widely used in mechanical equipment and automated assembly lines. There are many types of locating pins, including fixed locating pins, replaceable locating pins, tapered locating pins, edged locating pins, standard diamond locating pins, spring locating pins, etc. The function is to limit the free movement of parts and objects. Users often choose different positioning pins according to the actual conditions of the parts, for example, according to the occasion of use, requirements and performance, etc., to reasonably choose positioning pins of different shapes and performances. At present, users usually use a combination of cylindrical pins and edge-cutting positioning pins as the positioning method for gripper positioning methods in automatic line accompanying tooling and automatic grasping.
