Description

Workpiece holding mechanism of polishing device

The present invention relates to a polishing apparatus, and more particularly to a workpiece holding mechanism of a polishing apparatus.

As shown in Fig. 6, the conventional fluid polishing structure mainly fixes the workpiece 81 to a space 82 through which the fluid can reciprocate, and a fluid 83 having a polishing function is disposed in the space 82, and is driven by the piston 84. The fluid 83 is reciprocated to perform a polishing operation on the workpiece 81.
However, the flow direction of the fluid driven by the piston 84 is generally fixed, and the workpiece 81 is a three-dimensional object having a plurality of faces, although the fluid has a polishing effect on each face of the workpiece 81, but the fluid is facing the fluid in the direction of the flow direction of the fluid. The effect of polishing is strong and obvious, and the non-pairing surface is weakened and not obvious by the effect of fluid polishing, resulting in inconsistent polishing effect of the workpiece 81 as a whole.
According to the two new patent cases of the Republic of China Patent Publication No. 537098 and No. M402168, respectively, a polishing device for grinding with a polishing wheel (disc). The two polishing apparatuses shown in the above two novel cases are usually arranged in a plurality of discs (not shown) during polishing, and a plurality of workpieces (fixed or rotated) are disposed on the discs, each of which The polishing device adjusts the polishing angle of the polishing wheel (disc) at the set position to perform grinding of the respective polishing portions of the aforementioned workpiece. However, the polishing apparatus described above is complicated in structure due to the adjustment of the polishing wheel (disc), and must be provided in the actual grinding of the workpiece, so that it has a problem of large volume, space occupation, and high cost.
Therefore, how to solve the problem of the above-mentioned conventional polishing operation or device is the focus of this creation.

The main purpose of the present invention is to solve the above problems and provide a workpiece holding mechanism for a polishing apparatus, which can change the angle of all the workpieces as the rotating frame rotates, so that the workpiece can be fixed by a single workpiece holding mechanism. Each side of the workpiece is uniformly polished during grinding, and has a specific small size without occupying space and a low cost.
For the purposes of the foregoing, this creative department includes:
a shaft seat with a motor;
a drive shaft arm disposed on the shaft seat and driven to rotate by the motor;
A rotating frame is pivotally mounted on the transmission shaft arm, and is provided with a plurality of fixing devices for fixing the workpiece, and the rotating frame can be driven by the driving shaft arm to change the angle.
Wherein, the axle seat has a driving chamber; the transmission shaft arm has a bending section that passes out of the axle seat and is bent at an angle, and has a gear located at the driving compartment at an end away from the bending section, The motor has a gear and a gear meshing transmission of the drive shaft arm.
The above and other objects and advantages of the present invention will become more apparent from the detailed description and the accompanying drawings.
Of course, the present invention is allowed to differ in some of the parts, or the arrangement of the parts, but the selected embodiments are described in detail in the present specification, and the construction thereof is shown in the drawings.

Please refer to Fig. 1 to Fig. 5, which shows the structure of the embodiment selected for the present invention, which is for illustrative purposes only and is not limited by the structure in the patent application.
The embodiment provides a workpiece holding mechanism of a polishing apparatus, which comprises a shaft seat 1, a transmission shaft arm 2 and a rotating frame 3:
As shown in FIGS. 1 and 2, the shaft base 1 is provided with a motor 11, and the shaft base 1 has a drive chamber 12 in this embodiment. The drive shaft arm 2 is disposed on the shaft base 1 and is rotated by the motor 11 to rotate. . The rotating frame 3 is pivotally disposed on the transmission shaft arm 2, and is provided with a plurality of fixing devices 4 for fixing a workpiece (not shown), and the rotating frame 3 can be driven by the driving shaft arm 2 to change the position of the rotating frame 3 angle. The transmission shaft arm 2 of the embodiment has a bending section 21 which is bent out of the shaft seat 1 and bent at an angle (the bending section 21 of the embodiment is bent at an angle of 135 degrees) and away from the bending section One end of 21 has a gear 22 located in the driving chamber 12, and the motor 11 has a gear 111 and a gear 22 meshingly driven, whereby the transmission shaft arm 2 can be driven to rotate by the coupled motor 11, and the rotating frame 3 can be rotated. The angle at which the drive shaft arm 2 is rotated changes.
As shown in FIG. 3, the workpiece holding mechanism of the present embodiment is actually used in the fluid polishing apparatus 5. The fluid polishing apparatus 5 shown in the drawing is provided with a column 52 on the base 51 and on the column 52. A rotation groove 53 is pivotally provided, and the column 52 is provided with a seat body 54 which is displaceable along the longitudinal direction thereof. The workpiece holding mechanism is fixed to the seat body 54 by the shaft seat 1. The rotating groove 53 accommodates a fluid 55 for polishing the object. When the workpiece is polished, the seat 54 can be moved downward, and the holder 4 can be immersed in the fluid 55 with the rotating frame 3 to perform grinding and polishing. action.
As shown in FIG. 4, when the rotating frame 3 is immersed in the fluid 55 for grinding and polishing, the rotating frame 3 can be 360 in the fluid 55 by the bending angle of the bending section 21 by the rotation of the transmission shaft arm 2. The degree of free swing, at this time, due to the rotation of the rotating groove 53, the fluid 55 will flow through the rotating frame 3 in the rotating direction of the rotating groove 53, and the workpiece fixed by the fixing device 4 can be rotated 360 degrees in accordance with the rotation of the driving shaft arm 2. The range is swung to any angle, so that the workpiece fixed by the holder 4 can achieve a uniform polishing effect in the fluid 55.
The workpiece holding mechanism of this embodiment can be applied to the physical polishing of the grinding wheel in addition to the fluid polishing described above. As shown in Fig. 5, a grinding wheel 6 for grinding and polishing the workpiece is provided at an appropriate position, and the workpiece fixed by the holder 4 (not shown) can also be rotated 360 degrees with the rotation of the transmission shaft arm 2. The range is swung to any angle, and the workpiece can be swung to different faces under the fixing of the holder 4, and can be uniformly polished and polished by the grinding wheel 6. Therefore, a single workpiece holding mechanism can achieve a uniform polishing effect, and it is relatively advantageous to have a small volume without occupying space and a low cost compared to a plurality of polishing apparatuses.
From the above description, it is not difficult to find that the advantage of the present invention is that whether it is fluid polishing or physical polishing with a grinding wheel, the polished workpiece only needs to be fixed on the holder 4 and is rotated by the transmission shaft arm 2 to swing to the selected one. The position can obtain the effect of uniform polishing, and the action can be completed on the same workpiece holding mechanism, so that the conventional fluid polishing can not uniformly achieve the polishing effect, and the polishing device is bulky and costly.
The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.
From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application.
