Detailed Description

The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings:

referring to fig. 1 to 4, the present invention provides a thread rolling machine 10, wherein the thread rolling machine 10 is mainly used for the thread rolling operation of small screws, which are commonly used in wearable devices or smart phones. The thread rolling machine 10 has a driving assembly 11, a thread rolling seat 12, a thread rolling die 13, a feeding path 14, a vibrating assembly 15, an air supply assembly 16 and a feeding member 17. The driving assembly 11, the thread rolling tool holder 12 and the thread rolling tool plate 13 disclosed in the present invention are commonly used structures in the field, and are only briefly described later, but still do not affect the understanding of the aforementioned structures by those skilled in the art. The driving assembly 11 is composed of a plurality of mechanical structures and at least comprises a motor. The holder 12 is fixed and the thread rolling die 13 is movable to perform thread rolling operation in cooperation with the holder 12. The thread rolling cutter plate 13 is driven by the driving component 11 to reciprocate linearly (131 shown in fig. 2) relative to the thread rolling cutter seat 12.

It is different from the conventional one, the feeding channel 14 of the present invention is horizontally disposed, and the feeding channel 14 is used for conveying at least one material to be rubbed with teeth. Furthermore, the vibration component 15 is connected with the feeding channel 14, and the vibration component 15 will vibrate after being started and bring the feeding channel 14 to vibrate integrally. It should be understood that the vibration generated by the vibration assembly 15 only needs to be enough to make the material to be twisted conveyed on the feeding channel 14 generate a small amount of bounce, and excessive vibration will easily cause the material to be twisted to fall off abnormally. In one embodiment, the vibration element 15 may be a vibration motor. In addition, in order to enable the vibration component 15 to vibrate the feeding channel 14, in one embodiment, the feeding channel 14 is made of aluminum. The air supply assemblies 16 are disposed corresponding to the feeding channel 14, and the air supply assemblies 16 are disposed at intervals along the feeding path of the feeding channel 14, and the distance between the air supply assemblies 16 may be fixed or not fixed. Each of the air supply assemblies 16 receives a feeding air from an air supply source (not shown) and provides the feeding air to the feeding channel 14, so that the material to be rubbed fed into the feeding channel 14 is pushed to move toward the feeding member 17. The air supply direction of each air supply module 16 is substantially the same. Furthermore, the feeding member 17 is disposed at the end of the feeding channel 14, and the feeding member 17 is driven by the driving component 11 to have a linear reciprocating feeding track 171. The feeding track 171 of the feeding member 17 is perpendicular to the thread rolling cutter 13, that is, the thread rolling machine 10 of the present invention adopts 90-degree feeding thread rolling during thread rolling operation. Accordingly, the feeding member 17 conveys the material to be thread rolling from the end of the feeding channel 14 toward the thread rolling cutter plate 13. On the other hand, the feeding channel 14 defines an extension line 141, and the extension lines 141 intersect with the feeding track 171 and together define an included angle 142 smaller than or equal to 90 degrees.

It should be noted that the utility model discloses a vibration of this pay-off way 14 and this pay-off gas that these air feed subassembly 16 provided make the tiny should wait to rub the tooth material piece and can really carry on this pay-off way 14, solved the problem that the conventional structure of rubbing the tooth machine takes place to carry unusually easily.

Referring to fig. 3 and 4 again, in an embodiment, the thread rolling machine 10 includes a limiting plate 18 and a pressing head 19 disposed at an end of the limiting plate 18 close to the feeding member 17. Wherein, the limiting plate 18 is arranged corresponding to the feeding channel 14 to prevent the material piece to be rubbed with teeth from falling off in the conveying process, and the length of the limiting plate 18 at least conforms to the length of the feeding channel 14. The limiting plate 18 is stacked on the feeding channel 14, but a space 20 still exists between the limiting plate 18 and the feeding channel 14, and the space 20 is used for generating a space between the feeding channel 14 and the limiting plate 18 for allowing the material to be twisted to slightly jump. Furthermore, a boss 181 is formed at one end of the limiting plate 18 where the pressing head 19 is disposed, the pressing head 19 can swing relative to the limiting plate 18 by taking a portion of the pressing head 19 coupled to the limiting plate 18 as an axis, a pressing end 191 and an end 192 not pressed are respectively disposed at two horizontal ends of the pressing head 19, a limiting rod 193 disposed at the pressing end 191 and a spring 194 disposed at the end 192 not pressed are disposed on the pressing head 19, and two ends of the spring 194 are respectively connected to the pressing head 19 and the boss 181. Furthermore, the purpose of the material pressing head 19 of the present invention is to avoid the carry error of the material to be rubbed with teeth when entering the feeding track 171 of the feeding member 17. In addition, the pressing head 19 is limited by the limiting rod 193 and the spring 194, and more specifically, the plane of the pressing head 19 for pressing the material to be rubbed cannot interfere with the movement of the feeding member 17, and the contact point of the limiting rod 193 with the boss 181 during the swinging process of the pressing head 19 determines the plane position of the pressing head 19, so the length of the limiting rod 193 is very important. In one embodiment, the stop lever 193 is a threaded rod that is adjustable by an operator.

Naturally, the present invention can be implemented in other various embodiments, and various changes and modifications can be made by those skilled in the art without departing from the spirit and the essence of the present invention, but these changes and modifications should fall within the scope of the present invention defined by the appended claims.
