Counterweight structure of eccentric disk for thread rolling machine

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 to the eccentric disc of the thread rolling machine, with the thread rolling unit and the counterweight unit positioned at an angle. When the eccentric disc drives the thread rolling unit to perform thread rolling, it simultaneously drives the connected counterweight unit to operate. This causes 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 substantial benefits such as improving screw quality and yield.

Description

Technical Field

[0001] This invention relates to the technical field of dental thread rolling machines, and more particularly to a counterweight structure for an eccentric disc of a dental thread rolling machine. Prior Technology

[0002] Currently, screws are mainly manufactured using thread rolling machines. Each thread rolling machine has 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 the formed threads.

[0003] However, modern industries not only emphasize 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 rotational power source to increase the operating speed of the moving thread rolling plate, thereby increasing screw production capacity. However, as the operating speed of the moving thread rolling plate increases, the amplitude of wobbling of the moving thread rolling plate also increases, making the moving thread rolling plate prone to collision deformation and other damage. At the same time, when rolling the screw blanks, 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.

[0004] The reason is that, in view of the above-mentioned shortcomings in the use and implementation of existing tooth-rolling machines, the inventor, with the help of many years of manufacturing and design experience and knowledge in related fields, and through various ingenious ideas, has created this invention. Summary of the Invention

[0005] 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 ensuring screw quality.

[0006] To achieve the aforementioned objectives, the inventors have devised the following counterweight structure for an eccentric disc of a tooth-rolling machine, comprising a body, a transmission unit, and a tooth-rolling unit. The transmission unit includes an eccentric disc and a first connecting rod. The tooth-rolling unit includes a movable tooth plate and a fixed tooth plate that is positioned corresponding to and parallel to the movable tooth plate. The eccentric disc 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 tooth plate. Its distinguishing feature is:

[0007] A counterweight unit includes a second link and a counterweight assembly. One end of the second link is eccentrically connected to the eccentric disc, and the other end of the second link is connected to the counterweight assembly. The toothed unit is set at an angle to the counterweight unit.

[0008] In the counterweight structure of the eccentric disc of the tooth-rolling machine described above, the included angle between the tooth-rolling unit and the counterweight unit is 90 to 180 degrees.

[0009] The counterweight structure of the eccentric disc of the tooth-rolling machine as described above, wherein the counterweight unit includes at least one counterweight block.

[0010] The counterweight structure of the eccentric disc of the tooth-rolling machine as described above, wherein the counterweight unit comprises a number of counterweight blocks.

[0011] As described above, the counterweight structure of the eccentric disc of the tooth-rolling machine includes a set of vertical holes at one end of the second connecting rod, and a set of vertical blocks eccentrically provided on the eccentric disc. The set of vertical holes of the second connecting rod is sleeved with the set of vertical blocks of the eccentric disc, so that one end of the second connecting rod is eccentrically connected to the eccentric disc.

[0012] As described above, the counterweight structure of the eccentric disc of the tooth rolling machine further includes a sleeve with a hole along its length. The counterweight system is movably fitted into the hole of the sleeve, and the sleeve is inclinedly assembled on the machine body.

[0013] 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.

[0014] As described above, the counterweight structure of the eccentric disc of the tooth rolling machine has a shaft hole at its center. A rotary power source is also provided in the machine body assembly. The rotary power source is connected to a transmission shaft, which is connected to the shaft hole of the eccentric disc.

[0015] 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 substantial benefits such as screw quality and yield.

[0017] To more fully and clearly disclose the technical means and effects of this invention, a detailed description is provided below, along with the disclosed drawings and figures:

[0018] First, please refer to the first figure, which shows the counterweight structure of the eccentric disc of the thread rolling machine of the present invention. It mainly includes a machine body (1), and a guide rail (2) is inclinedly arranged on the machine 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 machine body (1). The transmission unit (4) includes an eccentric disc (41). The eccentric disc (41) is formed Having a first surface and a second surface, the eccentric disk (41) is eccentrically mounted on one side of its first surface with a first connecting rod (42) at one end. The other end of the first connecting rod (42) is mounted with the movable jaw plate (31). Please refer to the second figure for reference. The eccentric disk (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 pulley set, and the transmission shaft (431) is connected to the shaft hole (411) of the eccentric disk (41). The feature is that:

[0019] A counterweight unit (5) includes a second connecting rod (51). One end of the second connecting rod (51) is provided with a circular assembly hole (511), and a circular assembly block (412) is eccentrically provided on the second surface of the eccentric disk (41). Please refer to the third figure. The circular assembly hole (511) of the second connecting rod (51) is correspondingly fitted with the circular assembly block (412) of the eccentric disk (41), so that one end of the second connecting rod (51) is eccentrically assembled on the eccentric disk (41), and the other end of the second connecting rod (51) is connected to... The assembly includes a counterweight unit (52), 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 unit (52) is movably fitted into the sleeve hole (531) of the sleeve (53). The sleeve (53) is inclinedly assembled on the body (1), so that the counterweight unit (5) and the tooth rolling unit (3) are set at an angle (θ) of 90 to 180 degrees (as shown in Figure 6).

[0020] Accordingly, when in 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 connected eccentric disk (41) to rotate. 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) to reciprocate linearly, so as to perform thread rolling action on the screw blank together with the fixed tooth plate (32), and thus the screw blank is formed with threads.

[0021] When the eccentric disc (41) drives the movable tooth plate (31) to reciprocate via the first connecting rod (42), the eccentric disc (41) synchronously drives the second connecting rod (51) and its counterweight unit (52) connected to it to reciprocate linearly along the sleeve (53). At this time, please refer to Figure 6. The first oblique force (F) generated by the linear motion of the movable tooth plate (31) of the inclined tooth rolling unit (3) can be 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) and its counterweight unit (52) 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.

[0022] Therefore, when the first horizontal component force (F1) that mainly causes the shaking of the moving tooth plate (31) of the thread rolling unit (3) is effectively eliminated, when the user increases the operating speed of the moving tooth plate (31) to increase screw production capacity, the moving tooth plate (31) can be prevented from being violently shaken due to high-speed operation, which would cause collision deformation and damage to the moving tooth plate (31). In addition, the moving tooth plate (31) can also be prevented from being damaged due to shaking, such as chipping or uneven tooth depth when the screw blank is rolled into threads. Thus, the actual benefits of increasing screw production capacity and ensuring screw quality yield are achieved.

[0023] The foregoing embodiments or diagrams are not intended to limit the implementation of the present invention. The counterweight unit (5) of the present invention may include a number of counterweight blocks in its counterweight structure (52). In this way, the required counterweight weight can be adjusted in the counterweight unit (5) according to the shaking amplitude generated by the operation of the tooth-rolling unit (3). Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.

[0024] As can be seen from the above structure and implementation methods, the present invention has the following advantages:

[0025] 1. The counterweight structure of the eccentric disc of the thread rolling machine of the present invention is that a counterweight unit is connected to the eccentric disc and is set at an angle with the thread rolling unit. In this way, when the eccentric disc drives the thread rolling unit to operate, the counterweight unit connected to the eccentric disc operates synchronously, so as 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 shake is eliminated, the screw production capacity and screw quality yield can be substantially improved.

[0026] 2. The counterweight structure of the eccentric disc of the tooth-rolling machine of the present invention is that a number of counterweight blocks are provided in the counterweight unit. In this way, the required counterweight can be adjusted according to the shaking amplitude generated when the tooth-rolling unit is operating, so as to balance and counteract the shaking generated when the tooth-rolling unit is operating, thereby effectively improving the operating stability of the tooth-rolling machine.

[0027] In conclusion, the embodiments of the present invention can indeed achieve the expected effects, and the specific structure disclosed therein 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, we hereby file an application for an invention patent in accordance with the law, and respectfully request your review and grant of a patent, which would be of great benefit.
