Description

Technical Field

[0001] The utility model relates to the technical field of piano manufacturing and processing, and particularly relates to a drilling device for the grand piano's total rail. Background Art

[0002] There are automatic drilling problems for 4 types of grand piano's total rails, namely the coupler rail, the hammer shank rail, the regulating rail, and the damper rail. The existing processing technology: for drilling the grand piano's total rail, manual scribing is used to measure the position, marks are made on the total rail, and then the operator manually moves the workpiece to align with the marked position, and the bench drill is controlled to drill 88 kinds of nail holes one by one on the total rail.

[0003] In the existing processing technology, there are the following disadvantages: 1. Each time of processing requires prior measurement, and the accuracy of manual measurement and positioning is relatively low. The marks are made by manually scribing with a pencil, and the intersection points of the long vertical line and multiple horizontal lines are used to represent the drilling positions. Therefore, the measurement accuracy varies with the personal technical level and working state of the operator; 2. The existing drilling method uses a simple bench woodworking drill press. The drilling depth depends on the feeling of hand pressure and visual judgment of the human eye, and it is impossible to achieve unified processing accuracy. There is a phenomenon that the drilling depths of the same pair or different pairs of workpieces are inconsistent; 3. The model conversion time is long: the 4 types of grand piano's total rails are divided into 4 categories. Each time when changing the variety, it takes a lot of additional processing time to adjust the positions of the drill press workbench and the positioning plate so that the drill bit of the drill press can accurately complete the drilling work. 4. The workpiece processing time is long: the blanks of these four types of grand piano's total rails are imported original parts, with high import costs, and are specially used for manufacturing high-grade grand piano products. Therefore, the allowable scrap rate for processing is 0. Under this requirement, the operator will focus and carefully process during part processing to ensure that the processing quality is the first, and do not pursue processing efficiency, resulting in low processing efficiency of this processing procedure.

[0023] As Figure 1 shown, this embodiment provides a drilling device for the total file of a grand piano, including a workbench 1, a gantry 2, a drilling mechanism 3, and a clamping mechanism; the gantry 2 is arranged on the workbench 1, the drilling mechanism 3 is slidably arranged on the gantry 2, the clamping mechanism is arranged on the workbench 1 and is located below the gantry 2; the clamping mechanism clamps and fixes the total file 8, and the drilling mechanism 3 moves along the axis direction of the total file 8 and drills holes in the total file 8, so as to ensure the accuracy of the hole positions of the total file 8 and improve the drilling efficiency.

[0024] As Figures 2 - 3As shown in the figure, due to the different machining reference surfaces and the depths of the machined holes of the different overall gears 8, as a preferred solution, the clamping mechanism includes a positioning seat 4, a baffle 5, a support and positioning assembly 6, and a clamping and fixing assembly 7. The positioning seat 4 is strip-shaped, and the shape of the top surface of the positioning seat 4 is adapted to the shape of the bottom end of the overall gear 8. The overall gear 8 is placed on the support and positioning assembly 6. The baffle 5 is arranged on the workbench 1, and one end of the positioning seat 4 and the overall gear 8 abuts against the baffle 5 to realize the axial positioning of the positioning seat 4 and the overall gear 8. The support and positioning assembly 6 is arranged on the workbench 1 and is used for clamping and positioning the positioning seat 4. The clamping and fixing assembly 7 is arranged on the workbench 1 and is used for clamping and positioning the overall gear 8.

[0025] Specifically, the positioning seat 4 is replaceable, and there is one positioning seat 4 corresponding to each type of overall gear 8. With the support of the positioning seat 4, the reference surfaces of each overall gear 8 are kept horizontal, and the bottom surfaces of the machined holes of all the overall gears 8 are at the same height. In this way, when machining different overall gears 8, only the corresponding positioning seat 4 needs to be replaced, and there is no need to set and adjust the feed stroke of the drilling mechanism 3, which can realize the rapid connection of the machining of different batches of overall gears 8 and improve production efficiency.

[0026] As Figures 1 - 3 shown in the figure, as a preferred solution, the support and positioning assembly 6 includes a reference plate 61 and a push-pull type quick clamp 62. The reference plate 61 and the push-pull type quick clamp 62 are arranged opposite to each other and are used for clamping the positioning seat 4. The reference plate 61 provides a horizontal reference for one side of the positioning seat 4, and using the quick clamp is convenient for operation and improves efficiency.

[0027] Furthermore, the support and positioning assembly 6 further includes a support block 63, and the support block 63 is arranged at the output end of the push-pull type quick clamp 62. Specifically, the support block 63 is in an "L" shape and includes a support portion 631 and a clamping portion 711. The support portion 631 is used for supporting the positioning seat 4, and the clamping block and the reference plate 61 cooperate to clamp the positioning seat 4. In this way, it can better adapt to the shape of the positioning seat 4 and provide a better support effect.

[0028] As Figures 1 - 3 shown in the figure, as a preferred solution, the clamping and fixing assembly 7 includes a pressing block 71 and a horizontal push cylinder 72. The pressing block 71 is arranged at the output end of the horizontal push cylinder 72. Specifically, the pressing block 71 is in an "L" shape and includes a clamping portion 711 and a limiting portion 712. The clamping portion 711 cooperates with the positioning seat 4 to clamp the overall gear 8, and the limiting portion 712 is used for limiting the overall gear 8 in the vertical direction. In this way, the overall gear 8 can be stably limited.

[0029] As Figure 1As shown, as a preferred solution, multiple groups of the support and positioning components 6 and the clamping and fixing components 7 are provided, and the multiple groups of the support and positioning components 6 and the clamping and fixing components 7 are arranged at intervals on both sides of the positioning seat 4; in this way, stable support can be provided.
