The working steps of the waist drum skin device will be described in detail with reference to fig. 13 to 15.
Step 1:
the empty waist drum 16Y to be skinned is placed in the fixing rubber ring 11 of the rotary base 9, the waist drum 16Y is preliminarily fixed, and the cut drum skin 21 is covered on the guide collar 81 of the guide bracket 8. At this time, neither the cylinder assembly 5 nor the lift table 10 has yet been activated.
Step 2:
as shown in fig. 13, the cylinder assembly 5 is started, the whole cylinder assembly 5 descends, and the whole shaping assembly K descends stably under the cooperation of the guiding shaft 163 and the guiding round hole 83 until the squeezing ball 20 of the squeezing assembly M butts against the upper surface of the drum head 21, and meanwhile, the guiding collar 81 of the guiding bracket 8 butts against the lower surface of the drum head 21, and the whole drum head 21 is primarily fixed. At this time, the waist drum 16Y is still positioned below the guide bracket 8 and does not contact the drum head 21.
And step 3:
as shown in fig. 14, the lift table 10 is activated, the waist drum 16Y is raised, and the top opening of the waist drum 16Y contacts the lower surface of the drum head 21.
And 4, step 4:
as shown in fig. 15, the lift table 10 continues to be raised. In this process, the drum head 21 is always firmly clamped between the squeeze ball 20 and the guide collar 81 and slides under the squeeze of the squeeze ball 20 until the drum head 21 completely covers the top opening of the waist drum 16Y, at which time the drum head 21 is flat and tight.
And 5:
starting the rotary base 9, the air cylinder component 5, the air cylinder bracket 6, the shaping component K, the guide bracket 8 and the waist drum 16Y all rotate synchronously along with the rotary base 9, starting the four nail gun components S, and finishing nailing and fixing of the drum skin of the whole waist drum 16Y when the rotary base 9 rotates 90 degrees. Of course, if one nail gun assembly S is used, the swivel base 9 needs to be rotated 360 degrees. In addition, manual nailing can also be adopted, the stepping motor is used for driving the rotating base 9, and when the rotating base 9 rotates by a fixed angle, nailing is stopped;
step 6:
the excess corners of drum skin 21 are cut away.
The following describes how the adjustment of the compression assembly M is performed. As shown in fig. 10, the user can adjust the depth of the fixed cylinder 17 in the setting screw hole 1611 by means of the external adjustment thread 172 of the fixed cylinder 17 engaged with the setting screw hole 1611, thereby adjusting the protruding height of the squeeze ball 20 and thus precisely adjusting the pressure of the squeeze ball 20 against the drum head 21. By using the internal adjusting thread 173 of the fixed cylinder 17 and the disc thread 191 of the adjusting disc 19, the user uses a screwdriver to abut against the cross-shaped adjusting notch 192, and precisely adjusts the initial deformation amount of the pressure spring 18, so that the pressure and the maximum retraction distance of the squeeze ball 20 are precisely adjusted to adapt to the drum head with different materials and thicknesses. In addition, the squeeze ball 20 may be made of steel or hard nylon, and is mainly determined by the material and thickness of the drum head.
The waist drum skin device has the following advantages: the mechanical operation is used for replacing manual operation, so that the drum making efficiency is greatly improved, the labor cost is reduced, and the labor intensity of workers is greatly reduced. In addition, due to the adoption of automatic nailing, the heights of the drum nails are consistent, the drum nails are neat and beautiful, and the consistency of products is effectively improved.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
