Description

Threading machine pusher transmission

The invention relates to a squeegee pusher transmission device, which is characterized in that when the pusher slide seat group is stuck and cannot be actuated due to abnormal pushing material, the elongated hole and the push rod pivot can be connected by the connecting piece The elongated hole design absorbs the actuation distance generated by the eccentric runner linkage to avoid damage to the boring machine and further facilitates the pusher slide group to push the material smoothly.

According to the Republic of China Patent Announcement No. M248539, the new type of patent for the improvement of the structure of the boring machine (2), which is mainly based on the transmission of a transmission rod driven by a power source via a pulley, and the transmission rod The driving gear meshes the driven gear on the linkage rod, and the main gear fixed on the rotating shaft is engaged by the heart gear on the linkage rod, and one end of the rotating shaft is eccentrically assembled with the sleeve of the swing arm, and the sleeve is placed in the sleeve. One end of the connecting rod, and an elastic member is sleeved on the connecting rod of the end, and the two ends of the elastic member are respectively blocked from the connecting rod and the connecting tube, and the limit is set on the connecting rod near the other end. a member for limiting the length of the connecting rod to be inserted into the ferrule, and the other end of the connecting rod is arranged with the spherical cylinder to be splayed by the spherical bearing to absorb the yaw angle when the entire swing arm is actuated, and the output of the rotating cylinder A linkage piece is connected with the feeding rod to connect the dentition group that is connected with the feeding rod.

However, the structure of the above-mentioned boring machine is improved. (2) Although the swing arm of the rotary shaft and the rotary cylinder is composed of a ferrule, an elastic member and a connecting rod, one end of the ferrule is connected to the rotating shaft. And the end of the connecting rod is disposed at the end of the connecting rod, and the elastic member is sleeved on the end, and the other end of the connecting rod is arranged with the rotating cylinder; according to the design of the swing arm, the structural part is complicated, and if the part is damaged That is, it is impossible to absorb the moving distance generated by the linkage of the rotating shaft .

Therefore, the inventors of the present invention have the above-mentioned deficiencies in view of the conventional structure improvement of the dentition machine (2), and are potential research and development, and have been able to design the present invention.

The invention relates to a squeezing device pushing device, which mainly connects an eccentric rotating wheel and a rotating cylinder and a connecting rod on the boring machine, one end of the connecting rod is connected with the eccentric rotating wheel, and the connecting rod The other end is connected with the rotary cylinder, and the connecting end of the connecting end of the rotating end of the rotating cylinder is formed with an elongated hole design, and the open end of the connecting piece is connected with the pushing rod, and the pushing rod and the connecting piece are pivoted to form an elongated shape. The hole is designed, and the other end of the push rod is engaged with the push slide block; thereby, the link is interlocked with the rotary cylinder and the push rod, and the push slide group is stuck due to abnormal pushing of the push material. At the same time, the elongated hole of the connecting piece and the elongated hole of the push rod are designed to absorb the working distance generated by the interlocking of the eccentric wheel, so as to avoid damage of the boring machine and further the pushing block. The group pushes the smooth.

With respect to the present invention, the preferred embodiments and the structures and structures used to achieve the above objects and effects are described in detail with reference to the drawings. First, please refer to the first to third figures. The boring machine of the present invention is provided with a power transmission group A in the machine group, and the power transmission group A is provided with an eccentric rotation wheel (1) and a rotary cylinder (3) and a connecting rod (2), the connecting rod (2) One end of the connecting rod is connected to the eccentric rotating wheel (1), and the other end of the connecting rod (2) is arranged with the rotating cylinder (3), and the connecting piece (31) of the conveying end of the rotating cylinder (3) has a ㄈ shape design The ends are each formed with an elongated hole (311) design, and the open end (32) of the connecting piece (31) is connected to the pivot a push rod (41) is provided, and the push rod (41) and the open end (32) of the connecting piece (31) are connected to the pivoting portion to have an elongated hole, and the screw body (6) is provided with a block body (61), the blocks (61) are respectively accommodated in the elongated holes (311) for screwing the set (6) to connect the open end (32) of the connecting piece (31) to the pivoting push rod (41) An elongated hole (411) at one end, and the other end of the push rod (41) is engaged with the push slide group (4), and the push slide group (4) is provided with an elastic member (42). If the elongated hole (411) at one end of the push rod (41) is in a struts, the connecting piece (31) is connected to the elongated hole of the pivoting push rod (41) at one end to ensure the normal state is maintained. The power connection of the material.

Accordingly, please refer to the fourth to seventh figure, when the power transmission group A rotates the eccentric wheel (1), because one end of the connecting rod (2) is connected with the eccentric wheel (1), the connecting rod (2) ) forming a reciprocating swing within a certain distance, and thus driving the rotary cylinder (3) to rotate, and causing the push rod (41) pivoted with the rotary cylinder (3) to interlock with the push slide block (4) to reciprocate Material action.

Here, please refer to the eighth figure, when the screw blank is conveyed to the push slide group (4) via the feed rail (5), the push slide group is caused by the blanking or the screw blank abnormality. (4) When the jamming is unable to reciprocate, the pusher bar (41) connected to the pusher slide group (4) cannot be actuated, but since the power transmission group A still rotates the eccentric runner, The connecting connecting rod (2) and the rotating cylinder (3) are still continuously operated, and the elongated hole (311) and the push rod (41) of the connecting piece (31) of the rotating cylinder (3) can be used. The elongated hole (411) absorbs the reciprocating working distance of the connecting rod (2) and the rotating cylinder by the rotating eccentric rotating wheel of the power transmission group A, so that the operation is stopped by the elongated shape of the connecting piece (31) The hole (311) and the elongated hole (411) of the push rod (41) are moved to achieve the loss of the structure of each part of the tooth decay machine when the drive is pushed.

As can be seen from the above embodiments, the present invention has the following advantages:

1. The squeegee pushing device of the invention is designed by the elongated hole of the connecting piece of the rotating cylinder, and the long hole design of one end of the ejector rod is arranged to effectively prevent the power transmission when the pushing slide group is abnormally stopped. The reciprocating displacement of the long hole of the connecting piece and the long hole of the one end of the pushing rod is stopped, and the kinetic energy is continuously prevented from being damaged by the action of the pushing rod and the operation of the whole group of the sliding sliding block and the safety of the operator is affected.

2. The toothbrush pusher transmission device of the invention is a simple safety design, which is easy to assemble and repair, and reduces the production cost.

3. The toothbrush pusher transmission device of the invention is more time-saving and quick in eliminating the abnormality of the feeding, thereby improving the efficiency and increasing the productivity.

4. The squeegee pusher transmission device of the invention is designed such that the rotary cylinder and the push rod are more stable and not swaying, so as to reduce noise and increase the stability and smoothness of the pushing screw of the pusher slide group. .
