Service HotlineAt present, during assembly of many pin installation mechanisms, the pins need to be installed into the holes or arranged in an orderly manner, and there are many problems in this assembly method. First of all, during assembly, if the hole diameter of the hole product is large, when the pin enters the hole of the hole product, part of the pin entering the hole of the hole product is not fixed, which often leads to slight deviation. In addition, this assembly method is usually only suitable for parts with large apertures and small depths, and when installing multiple pins, it is impossible to automatically install all pins in place due to space constraints. Special tools need to be made for installation operations, and it is easy to cause pins. damage.
Most of the existing belts control the length of the belt by fixing the other end of the belt by the buckle, and the period that is often buckled by the buckle will be deformed and damaged after long-term use, and the user may change the position from standing to sitting or after meals. The circumference of the belt can be adjusted, and micro-adjustment is not necessarily possible when adjusting the tightness of the pin buckle type or buckle plate type belt buckle. In order to solve this problem, it is necessary to design a belt that is relatively suitable for the waist of a person.
In the process of automatically locking the screw to the product, there are only three types of screw supply mechanisms in the traditional automatic screw locking machine: 1. Magnet sucks for screws; 2. Vacuum sucks for screws; 7. Air blows for screws. The above three methods require long-distance screw supply, resulting in slow screw supply, low efficiency and high manufacturing cost. To this end, we propose an automatic locking screw machine that can directly supply screws.
The main purpose of the screw is to make the industrial product form a fixed one. In use, it often happens that the teeth cannot be closely attached, the screw head will be broken if the screw is locked too hard, or the tooth pattern is not properly locked, etc., and the use conditions are not met, all of which are quality. the problem of accuracy. Screws are mass products, not handmade works of art. In mass production, the purpose is to achieve high-precision and stable quality and popular prices to supply consumers. The accuracy of screws is usually 6g, and the rough screws used in construction projects are 10g. The value of screws is very important. In the world, there are examples of automobile factories going bankrupt because of poor screw quality; there are also examples of planes falling and vehicles being overturned because of poor screw quality.
Existing wood screws are composed of a threaded portion with a tapered angle and arranged along a tapered stem and a screw head. The head of the screw can be a countersunk head, hemispherical, or other shapes, and the head of the screw has a groove that fits with the tool, a word groove, and a concave cross groove. The taper angle of existing wood screws is either 45 degrees or 60 degrees, and the front end of the taper angle is a pointed point formed by a rotating thread. The existing wood screws have the following three deficiencies in use. Because the taper angle is 45 degrees or 60 degrees, and the thread angle is 71 degrees, the resistance when entering the material is relatively large, so the existing wood screws are manually screwed. It is difficult to screw in, especially when it is used for hardwood materials, and it often happens that the groove of the screw head is screwed out; A large lateral moment will be formed when the screw is screwed, which is prone to the problem of deviation from the position; in addition, because the existing screw is tapered, it will be subjected to both radial force and axial force when entering the material, and its stress state It is more complicated, so it is easy to cause the cracked wood material to burst, and even cause the material to have longitudinal cracks and be unusable.
