Description

Technical Field

[0001] This utility model relates to a grease injection lubrication device, and in particular to a grease injection lubrication device for the counterweight hammer of an electronic keyboard. Background Technology

[0002] When an electronic keyboard is in operation, pressing the keys (black or white) causes the counterweight hammers to rotate, making contact between the bottom of the keys and the contacts inside the keyboard, producing different notes. The counterweight hammers are used to simulate the resistance of striking a string. When the fingers leave the keys, the counterweight hammers return to their original position under the influence of gravity, causing the keys to return to their original position and separating the bottom of the keys from the contacts inside the keyboard.

[0003] In conventional pianos, there is dynamic friction between the top of the counterweight hammer and the bottom of the key. After the key is pressed for a long time, the top of the counterweight hammer and the bottom of the key will wear down. Continuous wear will cause the key to not return to its initial position after being pressed down, affecting the feel of pressing.

[0004] In summary, how to avoid wear between the top of the counterweight hammer and the bottom of the piano keys has become an urgent problem for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to avoid wear between the top of the counterweight hammer and the bottom of the piano key;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] Furthermore, it also includes: multiple vertically parallel second grease injection sections located behind the first grease injection section, with a grease injection port at the bottom of each section connected to a second grease injection nozzle, the second grease injection nozzle being moved by the moving module; the second grease injection nozzle includes: a second nozzle body, with a second nozzle head protruding from its front sidewall, and spray holes on the left and right sides of the second nozzle head; when the moving module moves the second grease injection nozzle between two adjacent black key support sections, grease is injected into the left and right sidewalls of the black key support section.

[0009] Furthermore, the moving module includes: an X-axis moving module, which is fixed to the operating table by a bracket; a Y-axis moving module, the movable end of the X-axis moving module being connected to the fixed end of the Y-axis moving module; a Z-axis lifting module, the movable end of the Y-axis moving module being connected to the fixed end of the Z-axis lifting module; a connecting plate, the movable end of the Z-axis lifting module being connected to the connecting plate, and two parallel cylinder seats being arranged in the front-rear direction of the connecting plate; a cylinder, which is fixed on the corresponding cylinder seat, and its output end is provided with a horizontal support rod, the first grease injection nozzle being fixed on the front support rod, and the second grease injection nozzle being fixed on the rear support rod.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] See Figure 1 , 2 4, 5, 7. This embodiment is a grease injection and lubrication device for the counterweight hammer of an electronic keyboard, including: an operating table 01 on which an electronic keyboard 02 is placed; and a plurality of vertically parallel first grease injection parts 1, the bottom of which are connected to first grease injection nozzles 11; a moving module 9 adapted to drive the first grease injection nozzles 11 to move; the first grease injection nozzle 11 includes: a first nozzle body 12, the front sidewall of which is horizontally recessed inward to form an opening 15 having two opposing inner walls 13 and a bottom wall 14, and first nozzle heads 16 with different orientations are provided at both inner walls 13 and bottom wall 14; when the moving module 9 moves the first grease injection nozzles 11 to the top of the counterweight hammer 03, the first nozzle heads 16 are oriented toward different sidewalls of the top of the counterweight hammer 03, and the first grease injection parts 1 inject grease into the top of the counterweight hammer 03.

[0023] In this embodiment, the first nozzle body 12 has a horizontally forward opening 15. The first nozzle body 12 is configured as two opposing inner walls 13 and a bottom wall 14. A forward-facing first nozzle head 16 is provided on the bottom wall 14, a right-facing first nozzle head 16 is provided on the left inner wall 13, and a left-facing first nozzle head 16 is provided on the right inner wall 13.

[0024] Place the electronic keyboard 02 on the operating table 01. Move the first grease injection nozzle 11 to the top of the counterweight hammer 03 using the moving module 9. Position the three first nozzles 16 on the left, right, and rear sides of the top of the counterweight hammer 03, respectively. The first grease injection unit 1 works to spray grease onto the top of the counterweight hammer 03. In this way, when the bottom of the key 04 contacts the top of the counterweight hammer 03, the key 04 or the counterweight hammer 03 will not wear out even after long-term use, thus extending the service life of the electronic keyboard.

[0025] It should also be noted that, since there are multiple first nozzle bodies 12, this device can achieve automatic and synchronized grease injection at the top of multiple counterweight hammers 03.

[0026] See Figure 1 , 3 4, 6, 7. The black key support part 05 is for the insertion of the rear end of the black key 06. The black key support part 05 is fixed inside the electronic keyboard 01. When the black key 06 is pressed, the black key 06 moves downward relative to the black key support part 05 until the black key 06 and the black key support part 05 come into contact and stop. In this way, relative motion friction also occurs between the black key 06 and the black key support part 05. In order to avoid wear between the black key support part and the black key, this embodiment uses multiple vertical parallel second grease injection parts 2, which are located behind the first grease injection part 1. The grease injection port at the bottom of the second grease injection part 2 is connected to a second grease injection nozzle 21. The second grease injection nozzle 21 is driven to move by the moving module 9. The second grease injection nozzle 21 includes: a second nozzle body 22, and a second nozzle head 23 protruding from the front side wall. The second nozzle head 23 has spray holes 24 on the left and right sides. When the moving module 9 moves the second grease injection nozzle 21 between two adjacent black key support parts 05, grease is injected into the left and right side walls of the black key support parts 05.

[0027] In this embodiment, a second nozzle head 23 is provided on the front side of the second nozzle body 11, and nozzle holes 24 are provided on the left and right sides of the second nozzle head 23. The moving module 9 moves the second nozzle head 23 to the adjacent two black key support parts 25, and the second grease injection part 2 works to spray grease onto the left and right side walls of the black key support parts 05 to achieve lubrication of the black key support parts 06.

[0028] Similarly, it should be noted that in this embodiment, since there are multiple second nozzle bodies 22, this device can achieve automatic synchronous grease injection of multiple black key support parts 05.

[0029] See Figure 1In some possible embodiments, to illustrate the specific structure of the moving module, this embodiment uses the moving module 9, which includes: an X-axis moving module 91, which is fixed on the operating table 01 by a bracket 90; a Y-axis moving module 92, the movable end of the X-axis moving module 91 being connected to the fixed end of the Y-axis moving module 91; a Z-axis lifting module 93, the movable end of the Y-axis moving module 92 being connected to the fixed end of the Z-axis lifting module 93; a connecting plate 94, the movable end of the Z-axis lifting module 93 being connected to the connecting plate 94, and two parallel cylinder seats 95 arranged in the front and rear directions of the connecting plate 94; a cylinder 96, which is fixed on the corresponding cylinder seat 95, and its output end is provided with a horizontal support rod 97, the first grease injection nozzle 11 is fixed on the front support rod 92, and the second grease injection nozzle 21 is fixed on the rear support rod 92;

[0030] In this embodiment, the X-axis moving module 91, the Y-axis moving module 92, and the Z-axis lifting module 93 realize the three-axis linear motion of the connecting plate 94, moving the first grease injection nozzle 11 above the top of the counterweight hammer 03, while the second grease injection nozzle 21 moves above the black key support part 05. The cylinder 96 is activated, lowering the first grease injection nozzle 11 to the top of the counterweight hammer 03. The other cylinder 96 is activated, lowering the second grease injection nozzle 21 between two adjacent black key support parts 05. The first grease injection part 1 and the second grease injection part 2 work to complete the grease injection of a group of counterweight hammers 03 and black key support parts 05. Then, the X-axis moving module 91, the Y-axis moving module 92, and the Z-axis lifting module 93 move to another group of counterweight hammers 03 and black key support parts 05 for the next grease injection, until all counterweight hammers 03 and black key support parts 05 have been greased.

[0031] See Figure 1 , 5 7. In some possible embodiments, the support rod 97 and the cylinder seat 95 are slidably arranged via a slide rail; a plurality of first grease injection nozzles 11 or second grease injection nozzles 21 are fixedly spaced at the bottom of the support rod 97.

[0032] In this embodiment, when the corresponding cylinder 96 is started, due to the sliding connection between the support rod 97 and the cylinder seat 95, the support rod 97 moves downward relative to the cylinder seat 95, lowering the first grease injection nozzle 11 to the top of the counterweight hammer 03, and lowering the second grease injection nozzle 21 between the two adjacent black key support parts 05 to inject grease.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
