DETAILED DESCRIPTION
[0016] The specific implementation of the utility model will be further described below in combination with the drawings. It needs to be explained here that the description of these implementation modes is used to help understanding the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] As Figs. 1-3 Indicated:
[0018] The utility model provides a guitar processing support device, including processing platform 1, vertical drive device 3 is installed above the center of processing platform 1 through support 2, vertical drive device 3 is connected with pressure solid assembly 4 to drive pressure solid assembly 4 to move up and down, pressure solid assembly 4 is composed of mounting shaft 41, pressure plate 43, movable pressure disc 44 and compensation pressure ring 45, pressure plate 43 is fixed at the bottom of mounting shaft 41, sets up threaded section 42 on the upper peripheral wall of mounting shaft 41, movable pressure disc 44 is screwed and is installed at threaded section 42, a circle of positioning ring 442 is arranged on the bottom of movable pressure plate 43 near the outer edge, the center of compensation pressure ring 45 has the positioning hole matched with the outer diameter of positioning ring 442, and the positioning ring 442 of movable pressure plate 43 is buckled into the positioning hole, a circle of sealing ring 451 is arranged on the bottom of compensation pressure ring 45 near the outer edge.
[0019] Working principle: during the use of the utility model, first, the sound box 5 of the guitar is placed on the processing platform 1, the bottom not needing to be processed is downward, the sound hole 51 on the sound box 5 is coaxially aligned with the mounting shaft 41, then the compensation pressure ring 45 is buckled on the sound hole 51, and the sealing ring 451 is buckled into the sound hole 51, so that the outer edge sealing and fixing of the sound hole 51 are completed.
[0020] The compensation pressure ring 45 is used to compensate the diameter difference between the movable pressure disc 44 and the sound hole, because the specifications of the sound holes of different specifications of guitars are different, but are within a certain range, so only different specifications of compensation pressure rings 45 need to be customized for different specifications of guitars, the whole movable pressure disc 44 does not need to be changed, and the cost can be greatly reduced.
[0021] After the compensation pressure ring 45 is installed, the vertical drive device 3 drives the pressure solid assembly 4 to descend, the pressure plate 43 penetrates through the sound hole and enters the sound box 5, abuts against the bottom wall of the sound box 5, and the fixing of the sound box 5 is completed, then the movable pressure disc 44 is rotated (in order to facilitate operation, a plurality of handles 441 can be arranged on the upper surface of the movable pressure disc 44 in a radial manner), the movable pressure disc 44 is caused to descend along the threaded section 42 until the positioning ring 442 is buckled into the positioning hole of the compensation pressure ring 45 and a certain pre-tightening is completed.
[0022] In order to increase the area of the pressure plate 43 as much as possible, reduce the pressure, and increase the friction area, the pressure plate 43 is circular, and a rubber pad 431 is bonded to the bottom of the pressure plate 43, and the diameter is close to but smaller than the size of the smallest specification sound hole.
[0023] The support 2 is processed into an inverted L shape, the vertical drive device 3 is fixed on the width center line of the processing platform 1 through the support 2, but deviates from the length center line (because the sound hole of the guitar is not on the length direction symmetry line, and is closer to one side).
[0024] The vertical driving device 3 comprises a servo motor 32, a screw rod 34, a sliding sleeve 31 and a screw sleeve 33; the sliding sleeve 31 is fixed with the support 2, the screw sleeve 33 penetrates into the sliding sleeve 31 from the bottom of the sliding sleeve 31 and slides in the sliding sleeve 31, the top end of the sliding sleeve 31 is provided with a bearing 35, the screw rod 34 is fixed through the bearing 35, penetrates into the screw sleeve 33 from the bottom and is connected with the servo motor 32 fixed at the top end of the sliding sleeve 31; the bottom end of the screw sleeve 33 is fixed with a mounting shaft 41.
[0025] The above structure is a screw rod sliding sleeve mechanism, the servo motor 32 drives the screw rod 34 to rotate, thereby dragging the screw sleeve 33 to slide up and down in the sliding sleeve 31 (the outer diameter section of the screw sleeve 33 and the outer diameter section of the sliding sleeve 31 adopt a regular quadrilateral or other non-circular section, which can realize the sliding), so as to drive the up and down operation of the pressing and fixing assembly 4, other similar mechanisms, such as a gas cylinder or a hydraulic rod, a gear chain mechanism, can be replaced as required.
