Abstract

This invention relates to a counterweight structure for an eccentric disc of a thread rolling machine. It mainly involves an eccentric connection between a thread rolling unit and a counterweight unit on the eccentric disc of the thread rolling machine, with the thread rolling unit and the counterweight unit positioned at an angle. Thus, when the eccentric disc drives the thread rolling unit to perform thread rolling, it simultaneously drives the connected counterweight unit to operate. This allows the horizontal component force generated by the thread rolling unit to cancel out the horizontal component force generated by the counterweight unit, effectively reducing the shaking of the thread rolling unit. Therefore, while increasing the operating speed of the thread rolling unit and increasing screw production capacity, it also achieves practical benefits such as improved screw quality and yield.

Description

Counterweight structure of the eccentric plate of a dental hand rolling machine.

This work relates to the technical field of dental floss machines, and in particular to a counterweight structure of an eccentric disc in a dental floss machine.

Note that existing screws are mainly manufactured using thread rolling machines. These machines have a thread rolling unit, which includes a movable thread plate and a fixed thread plate. A rotary power source is also located on the machine body, connected to an eccentric disc. The eccentric disc and the movable thread plate are connected by a connecting rod. When the screw blank is fed to the thread rolling unit, the eccentric disc drives the movable thread plate to reciprocate via the connecting rod, rolling the screw blank between the movable and fixed thread plates into threads.

However, modern industry not only emphasizes product quality but also production efficiency. Therefore, in order to improve screw production efficiency, existing manufacturers increase the rotation speed of the eccentric disc driven by the rotary power source to increase the operating speed of the swivel plate, thereby increasing screw production capacity. However, as the operating speed of the swivel plate increases, the swivel amplitude of the swivel plate also increases, making it prone to collision deformation and other damage. At the same time, when rolling the screw blanks into threads, it is also easy to cause chipping or uneven thread depth. As a result, existing thread rolling machines still cannot meet the requirements of both screw quality and high production capacity.

The reason is that, in view of the above-mentioned shortcomings of existing tooth-flush machines in practical use, the creator, with the help of his many years of experience and knowledge in manufacturing and design in related fields, and through a lot of ingenuity, created this creation.

This invention relates to a counterweight structure for an eccentric disc of a thread rolling machine. Its main purpose is to provide a structure that can effectively eliminate shaking during thread rolling, thereby improving screw production capacity while also ensuring screw quality.

To achieve the aforementioned objectives, the inventor has devised the following counterweight structure for an eccentric plate of a thread rolling machine, comprising a body, a transmission unit, and a thread rolling unit. The transmission unit includes an eccentric plate and a first connecting rod. The thread rolling unit includes a movable thread plate and a fixed thread plate that is positioned corresponding to and parallel to the movable thread plate. The eccentric plate is eccentrically mounted to one end of the first connecting rod, and the other end of the first connecting rod is mounted to the movable thread plate. Its features include:

A counterweight unit includes a second link and a counterweight assembly. One end of the second link is eccentrically connected to the eccentric plate, and the other end of the second link is connected to the counterweight assembly. The feeder unit is set at an angle to the counterweight unit.

In the counterweight structure of the eccentric plate of the tooth-rolling machine described above, the angle between the tooth-rolling unit and the counterweight unit is 90 to 180 degrees.

The counterweight structure of the eccentric plate of the teeth-rubbing machine as described above, wherein the counterweight unit comprises at least one counterweight block.

The counterweight structure of the eccentric plate of the teeth-rubbing machine described above, wherein the counterweight unit comprises a number of counterweight blocks.

As described above, in the counterweight structure of the eccentric plate of the tooth-rolling machine, one end of the second connecting rod is provided with a set of upright holes, and another set of upright blocks is provided eccentrically on the eccentric plate. The set of upright holes of the second connecting rod is sleeved with the set of upright blocks of the eccentric plate, so that one end of the second connecting rod is eccentrically connected to the eccentric plate.

The counterweight structure of the eccentric plate of the tooth-rolling machine described above further includes a sleeve with a hole along its length. The counterweight assembly is movably fitted into the hole of the sleeve, and the sleeve is inclinedly mounted on the machine body.

As described above, the counterweight structure of the eccentric disc of the tooth-rolling machine includes a guide rail on the machine body, the end of which extends to the tooth-rolling unit.

As described above, the eccentric plate of the tooth-rolling machine has a counterweight structure in which the eccentric plate has a shaft hole at its center, and a rotational power source is provided in the machine body. The rotational power source is connected to a transmission shaft, which is connected to the shaft hole of the eccentric plate.

Therefore, when the eccentric disc drives the thread rolling unit to perform thread rolling, it will simultaneously drive the counterweight unit connected to it to operate, so that the horizontal component force generated by the thread rolling unit and the horizontal component force generated by the counterweight unit can cancel each other out, thereby effectively reducing the shaking of the thread rolling unit. In this way, while increasing the operating speed of the thread rolling unit and increasing screw production capacity, it is possible to achieve practical benefits such as screw quality and yield.

To more fully and clearly reveal the technical means and effects achieved in this work, a detailed explanation is provided below. Please also refer to the revealed drawings and figure numbers:

First, please refer to the first figure, which shows the counterweight structure of the eccentric disc of the thread rolling machine of this invention. It mainly includes a body (1), and a guide rail (2) is inclinedly arranged on the body (1) to guide the screw blank. A thread rolling unit (3) is inclinedly arranged at the discharge end of the guide rail (2). The thread rolling unit (3) includes a movable tooth plate (31) and a fixed tooth plate (32) that is positioned opposite to and parallel to the movable tooth plate (31). A transmission unit (4) is provided on the body (1). The transmission unit (4) includes an eccentric disc (41). The eccentric disc (41) forms Having a first face and a second face, the eccentric disc (41) has a first connecting rod (42) eccentrically mounted on one side of its first face. The other end of the first connecting rod (42) is mounted with the movable jaw plate (31). Please refer to the second figure as well. The eccentric disc (41) has a shaft hole (411) at its center. A rotary power source (43) is mounted on the body (1). The rotary power source (43) is connected to a transmission shaft (431) through a gear set or a pulley set, and the transmission shaft (431) is connected to the shaft hole (411) of the eccentric disc (41). Its features are:

A counterweight unit (5) includes a second link (51). One end of the second link (51) is provided with a circular assembly hole (511), and a circular assembly block (412) is eccentrically provided on the second side of the eccentric plate (41). Please refer to the third figure as well. The circular assembly hole (511) of the second link (51) is correspondingly fitted with the circular assembly block (412) of the eccentric plate (41), so that one end of the second link (51) is eccentrically assembled on the eccentric plate (41), and the other end of the second link (51) is connected to... A counterweight assembly (52) is provided, which includes at least one counterweight block and a sleeve (53). Please refer to Figure 4 for details. The sleeve (53) has a sleeve hole (531) along its length. The counterweight assembly (52) is movably fitted into the sleeve hole (531) of the sleeve (53). The sleeve (53) is inclinedly mounted on the machine body (1), so that the counterweight unit (5) and the tooth rolling unit (3) are set at an angle of 90 to 180 degrees (as shown in Figure 6).

Accordingly, in practical use, the screw blank is transported from the guide rail (2) to the movable tooth plate (31) and fixed tooth plate (32) of the thread rolling unit (3). The rotational power source (43) of the transmission unit (4) drives the eccentric disk (41) connected to it to rotate. At this time, please refer to Figures 4 and 5. The first connecting rod (42) on one side of the eccentric disk (41) drives the movable tooth plate (31) of the eccentric assembly to reciprocate linearly, so as to perform thread rolling on the screw blank together with the fixed tooth plate (32), and thus the screw blank is formed with threads.

When the eccentric disc (41) drives the movable jaw plate (31) to reciprocate via the first connecting rod (42), the eccentric disc (41) synchronously drives the second connecting rod (51) and its counterweight assembly (52) of the counterweight unit (5) connected to it to reciprocate linearly along the sleeve (53). At this time, please also refer to Figure 6. The first oblique force (F) generated by the linear motion of the movable jaw plate (31) of the inclined jaw rolling unit (3) is... The force is decomposed into a first horizontal component (F1) and a first vertical component (F2). The second oblique force (W) generated by the linear motion of the counterweight unit (5) of the inclined counterweight unit (5) can be decomposed into a second horizontal component (W1) and a second vertical component (W2). The second horizontal component (W1) of the counterweight unit (5) is in the opposite direction to the first horizontal component (F1) of the tooth-rolling unit (3), thus forming a mutual cancellation effect.

Therefore, when the first horizontal component (F1) that mainly causes the shaking of the movable tooth plate (31) of the thread rolling unit (3) is effectively eliminated, when the user increases the operating speed of the movable tooth plate (31) to improve screw production capacity, the movable tooth plate (31) can be prevented from being damaged by collision and deformation due to violent shaking caused by high-speed operation. In addition, the movable tooth plate (31) can also be prevented from being damaged by the shaking of the screw blank during thread rolling, such as chipping or uneven tooth depth. This achieves the practical benefits of improving screw production capacity while taking into account screw quality and yield.

The foregoing embodiments or diagrams are not intended to limit the implementation of this invention. The counterweight unit (5) of this invention may contain several counterweight blocks in its counterweight assembly (52). In this way, the required counterweight weight can be adjusted in response to the shaking amplitude generated by the tooth-scraping unit (3) during the movement of the counterweight unit (5). Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this invention.

As can be seen from the above structure and implementation method, this invention has the following advantages:

1. The counterweight structure of the eccentric plate of the thread rolling machine of this invention is that a counterweight unit is connected to the eccentric plate and set at an angle with the thread rolling unit. In this way, when the eccentric plate drives the thread rolling unit to operate, the counterweight unit connected to the eccentric plate operates synchronously to cancel out the horizontal component force generated when the thread rolling unit operates. Thus, when the horizontal component force that causes the thread rolling unit to wobble is eliminated, the actual benefits of improving screw production capacity and screw quality yield can be achieved.

2. The counterweight structure of the eccentric plate of the tooth-flicking machine of this invention is that several counterweight blocks are set in the counterweight group of the counterweight unit. In this way, the required counterweight can be adjusted in response to the shaking amplitude generated when the tooth-flicking unit is operating, so as to balance and counteract the shaking generated by the operation of the tooth-flicking unit, thereby effectively improving the stability of the tooth-flicking machine.

In conclusion, the embodiments of this invention have indeed achieved the intended effect, and the specific structure disclosed herein has not only never been seen in similar products, but has also never been disclosed before the application. It fully complies with the provisions and requirements of the Patent Law. Therefore, I hereby file an application for a new type of patent and earnestly request your consideration and granting of the patent, which would be of great benefit.
