For a better understanding of the invention with objects, structures, features, and effects, the invention will be described further with reference to the drawings and to the detailed description. It should be noted that the features illustrated in the drawings are not necessarily drawn to scale. Furthermore, the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present invention fall within the protection scope of the present invention.
Unless defined otherwise, technical or scientific terms used in this disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The terms "first," "second," and the like, as used in this disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", "front", "rear", etc. are used merely to indicate relative positional relationships, which may also change accordingly when the absolute position of the object to be described changes. Furthermore, in the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
As shown in fig. 1 and 2, a processing apparatus 100 for a sub-key sheet dicing saw of a piano keyboard key according to an embodiment of the present invention includes a jig (not shown) for holding a key group 2 and a saw disc 1 for dicing saw. In this embodiment, the processing apparatus 100 is a five-way saw having five saw discs 1 for five-way sawing. The key group 2 is sawed by dividing the key group 2, so that the shape of the keyboard is sawed by the key group 2, and only the keys are sawed. The key group 2 includes keys 21 and a key sheet 22 provided on top of the keys 21. The material of the key 21 is wood, and the material of the key sheet 22 is plastic, and the key sheet 22 may also be referred to as a film. The key sheet 22 is a white key sheet and may be attached to the top surface of the key 21 by means of an adhesive.
The key group 2 has a first position and a second position in the fixture, when the key group 2 is in the first position, the height of the key sheet 22 corresponds to the height of the saw disc 1, so that the saw disc 1 can only saw the key sheet 22 but not the key 21; when the key set 2 is in the second position, the height of the keys 21 corresponds to the height of the saw blade 1 so that the saw blade 1 can saw the keys 21. Since the key piece 22 is sawn firstly and the key 21 is sawn afterwards, the phenomenon that when the key 21 is sawn, fragments of the key piece 22 splash to the two sides of the saw disc 1 to cause scraping of the two sides of the key 21 can be avoided, and the key piece 22 and the key 21 are respectively sawn, so that the key piece 22 and the key 21 are more stable when being sawn, and the key piece 21 and the key piece 22 are prevented from being sawn.
When the key group 2 is in the second position, a pad 3 for heightening the height of the key group 2 is provided below the key group 2. The position of the saw disc 1 is fixed and the key set 2 is in the first position when the key set 2 is placed directly in the holder. At this time, since the key 21 is at a low level, the saw disc 1 cannot be sawn to the key 21, and thus only the key sheet 22 is sawn. The base plate 3 is firstly placed in the fixture, then the key group 2 is placed above the base plate 3, the height of the key group 2 is increased, the height of the keys 21 is also increased, and at the moment, the saw disc 1 can saw the keys 21.
The embodiment further includes a first air compressor 4, where the first air compressor 4 is provided with a first presser finger 41, and the first air compressor 4 is configured to drive the first presser finger 41 to press the key set 2 downward. This ensures that the key set 2 remains stable when sawn.
The embodiment further comprises two second air presses 5, each second air press 5 is provided with a second pressing palm, and the two second air presses 5 are used for respectively driving the two second pressing palms to press the key sets 2 on two sides. By pressing the key group 2 on both sides by the second air press 5, the key group 2 can be made more stable so that the saw blade does not saw the key 21 or the key sheet 22.
Since the key sheet 22 has been sawn before, i.e. the key sheet 22 is sawn with a gap, when the saw disc 1 sawn the keys 21, the gap aligned with the key sheet 22 passes at the same time, and the film cannot be damaged. The clamp and the air compressor can ensure that the key set 2 is stable in other positions except the height, so that the saw disc 1 can be aligned with the gap of the key sheet 22.
The embodiment also comprises a machine table 6, and the clamp and the saw disc 1 are arranged on the machine table 6.
The embodiment also comprises a pushing plate, the clamp is arranged on the pushing plate, the machine table 6 is provided with a table top 61, the table top 61 is provided with a guide rail 7, and the pushing plate is in sliding connection with the guide rail 7. The pushing plate is used for pushing the key group 2 forwards to divide the saw, and the pushing plate automatically withdraws after the dividing saw is finished.
Based on the processing device 100, the invention also provides a processing method for the sub-key sheet saw of the piano keyboard, which comprises the following steps:
according to the size of the clamp, the key group 2 is directly placed into the clamp, the key group 2 is located at a first position in the clamp, the height of the key sheet 22 corresponds to the height of the saw disc 1, the key group 2 is pressed downwards through the first pressing palm 41 of the first air compressor 4, the key group 2 is pressed by the second pressing palm of the second air compressor 5 at two sides, so that the key group 2 is pressed, then a push plate on the machine table 6 is pushed forwards, the saw disc 1 only saw the key sheet 22 but not the key 21, and the push plate automatically exits after sawing is finished;
the base plate 3 is placed in a clamp of the machine table 6, the key set 2 is placed above the base plate 3, so that the key set 2 is located at a second position, the height of the key 21 corresponds to that of the saw disc 1, the key set 2 is pressed downwards through the first pressing palm 41 of the first air compressor 4, the key set 2 is pressed on two sides through the second pressing palm of the second air compressor 5, then a push plate on the machine table 6 is pushed forwards, the saw disc 1 saw the key 21, and the push plate automatically withdraws after sawing is completed.
The above detailed description is merely illustrative of the preferred embodiments of the invention and is not intended to limit the scope of the invention, so that all equivalent technical changes that can be made by the present specification and illustrations are included in the scope of the invention.
