[0034] like Figure 2-3 As shown, this embodiment provides a soaking device for a grand piano hammer handle shaft frame 4 (hereinafter referred to as: shaft frame 4), including: a workbench 1, a transfer mechanism, and a soaking mechanism; the shaft frames 4 enter the transfer mechanism one by one, and the transfer mechanism stands up the shaft frames 4 with their head ends facing downward and transfers them to the soaking mechanism. The shaft lining 41 in the shaft frame 4 is soaked in an emulsion through the soaking mechanism, which can realize the automation of its processing process and improve production efficiency.

[0035] like Figure 3-4 As shown, the transfer mechanism includes: a conveying device 21, a steering device 22, and a translation device 23; the input end of the conveying device 21 is connected to the previous process, and the shaft frame 4 is horizontally transferred to the conveying device 21 with the head end in front and the tail end in the back, and the steering device 22 is arranged on one side of the output end of the conveying device 21, and the steering device 22 clamps the head end of the shaft frame 4 and flips the shaft frame 490 degrees to stand up with the head end of the shaft frame 4 facing downward; the translation device 23 is arranged between the steering device 22 and the immersion mechanism, and the translation device 23 clamps the tail end of the shaft frame 4 and transfers the shaft frame 4 to the immersion mechanism.

[0036] like Figure 3-4 As shown, further, the conveying device 21 includes a conveyor belt 211 and a stopper 212. The stopper 212 is arranged at the output end of the conveyor belt 211 and is used to abut the shaft frame 4 to achieve axial positioning of the shaft frame 4, which is beneficial for the steering device 22 to accurately clamp the shaft frame 4.

[0037] like Figure 3-4 As shown, further, the steering device 22 includes a first clamping member 221 and a rotating assembly 222, the first clamping member 221 is used to clamp the head end of the shaft frame 4, the rotating assembly 222 and the first clamping member 221 are driven and connected, and the rotating assembly 222 drives the first clamping member 221 to rotate back and forth between the horizontal and vertical states.

[0038] like Figure 3-4 As shown, preferably, the rotating assembly 222 includes a first cylinder 2221, a rack 2222 and a gear 2223, the rack 2222 is arranged at the output end of the first cylinder 2221, the rack 2222 and the gear 2223 are meshed, and the first clamping member 221 is fixedly arranged on one side of the gear 2223; the stroke of the rack 2222 is one quarter of the stroke of the gear 2223, so that the rotation angle of the gear 2223 is fixed to 90 degrees. Compared with the use of a rotation drive device such as a servo motor, the rotation structure of this case sets its rotation angle through the original mechanical structure, which eliminates the need for program debugging and other work, and its structural principle is simpler, more reliable and durable.

[0039] like Figure 2-3 As shown, further, the translation device 23 includes a second clamping member 231 and a linear drive device 232, the second clamping member 231 and the linear drive device 232 are driven and connected, the second clamping member 231 clamps the tail end of the shaft frame 4, and the linear drive device 232 drives the second clamping member 231 to translate into the immersion mechanism.

[0040] In this embodiment, the linear drive device 232 is a component composed of a slide rail and a cylinder.

[0041] like Figure 2-3 As shown, the soaking mechanism includes: a soaking bucket 31 and two belt-type transmission belts 32; the soaking bucket 31 is filled with emulsion, and the two belt-type transmission belts 32 are horizontally spaced apart above the soaking bucket 31, and the adjacent sides of the two belt-type transmission belts 32 are clamping surfaces. The spacing distance between the two clamping surfaces is smaller than the outer diameter of the tail end of the shaft frame 4, and the rotation directions of the two belt-type transmission belts 32 are opposite, so that the transmission directions of the two clamping surfaces are the same, and the shaft frame 4 is clamped under the action of the belt elasticity, and through the cooperation of the two clamping surfaces, the shaft frame 4 is driven forward under the action of friction.

[0042] like Figure 2 As shown, specifically, the height of the belt-type transmission belt 32 is lower than the height of the second clamping member 231, the running speed of the belt-type transmission belt 32 is the same as the transmission speed of the linear drive device 232, and the starting position of the stroke of the belt-type transmission belt 32 coincides with the end position of the stroke of the linear drive device 232, which is conducive to the connection of the transfer of the shaft frame 4 between the second clamping member 231 and the belt-type transmission belt 32.

[0043] like Figure 2As shown, when the shaft frame 4 enters the vertical range of the soaking bucket 31, the height of the head end of the shaft frame 4 is higher than the soaking bucket 31 to prevent the shaft frame 4 from colliding with the soaking bucket 31 during movement, which may cause the shaft frame 4 to fall or shift; therefore, the soaking mechanism further includes a hammer device 33, which is located above the belt-type transmission belt 32 and the soaking bucket 31. The hammer device 33 is used to hammer the shaft frame 4 downward to make the shaft frame 4 move vertically downward during movement, so that after the shaft frame 4 enters the range of the soaking bucket 31, the head end of the shaft frame 4 is immersed in the emulsion in the soaking bucket 31.

[0044] like Figure 2-3 As shown, further, the hammer device 33 includes a second cylinder 331 and a hammer head 332 , the output end of the second cylinder 331 is vertically downward, and the hammer head 332 is arranged at the output end of the second cylinder 331 .

[0045] Furthermore, the rotation speeds of the two belt-type transmission belts 32 are not equal. Thus, in the process of the clamping shaft frame 4 moving forward, when there is a difference in the rotation speeds of the two belt-type transmission belts 32, the shaft frame 4 rotates along its axis during its forward movement, and the emulsion and the shaft lining 41 are better immersed in the pinhole of the shaft frame 4.

[0046] When the shaft frame 4 leaves the emulsion after being soaked, a lot of liquid will adhere to the surface of the shaft frame 4 and drip during the subsequent movement. The dripping emulsion will remain on the workbench 1, the ground or other equipment, causing pollution to the workshop environment and causing waste of emulsion. Figure 5 As shown, further, the immersion bucket 31 includes a foaming material section 301 and a recovery section 302, the foaming material section 301 and the recovery section 302 are connected and arranged in sequence along the conveying direction, the foaming material section 301 is filled with emulsion, and the recovery section 302 is not filled with emulsion. After the shaft rack 4 leaves the area of the foaming material section 301, the liquid adhered to the shaft rack 4 will drip onto the recovery section 302, so that the emulsion can be recovered without causing pollution to the surrounding area.

[0047] like Figure 5 As shown, specifically, the soaking hopper 31 includes: a bottom plate, three side plates, a first inclined plate 311 and a second inclined plate 312. The three side plates and the first inclined plate 311 are connected end to end in sequence and are arranged on the bottom plate to form the soaking hopper 31; the second inclined plate 312 and the first inclined plate 311 are arranged at intervals on the bottom plate, and the two ends of the second inclined plate 312 are respectively connected to the corresponding side plates, so that the soaking hopper 31 is separated into the foaming material section 301 and the recovery section 302.

[0048] like Figure 5As shown, preferably, the first inclined plate 311 and the second inclined plate 312 are arranged to be inclined, so as to reduce the collision of the shaft frame 4 with the edge of the soaking bucket 31 when leaving the soaking bucket 31, so that the shaft frame 4 is slowly tilted.

[0049] Preferably, a receiving tray is provided on the side of the soaking hopper 31 , and the receiving tray is located below the end of the belt-type transmission belt 32 . When the shaft frame 4 is transferred to the end of the belt-type transmission belt 32 , it will naturally fall onto the receiving tray.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
