Description

Technical Field

[0001] This utility model relates to the field of piano manufacturing and processing technology, specifically to a processing device for drilling rivet holes in hammers. Background Technology

[0002] The hammers are divided into low-pitched and mid-high-pitched sections according to the piano's design. The number of low-pitched hammers varies from 26 to 32, and the thickness of the wood core varies from 9.5, 10, and 10.5 mm depending on the model. The length of the hammers varies from 62 to 68 mm. The number of mid-high-pitched hammers varies from 68 to 62, the thickness of the wood core is uniformly 10.5 mm, and the length of the hammers varies from 70 to 79 mm.

[0003] The rivet hole must be drilled in the middle of the hammer, with a dimensional tolerance of ±0.1mm, and the drill axis must be perpendicular to the hammer core.

[0004] In response to these complex dimensional variations of the hammers, the current processing technology involves a simple mechanized drilling method. Holes are drilled using a fixed-position woodworking table, and the workpiece is placed on a fixture with multiple slots. The hammers are then manually placed one by one into the slots of the fixture, and the position of the drill hole on the absolute center line of the hammer thickness is manually controlled.

[0005] The resulting problems are as follows: 1. Drilling position is controlled manually by vision, and the firmness of workpiece positioning is controlled by the force applied by hand. The error range relative to the absolute center line of the hammer thickness varies greatly, and the machining accuracy is limited by the operator's mental state and professional skills, resulting in unstable machining quality. 2. Because movable fixtures are used to place the hammers before drilling, there are few fixture positions, requiring multiple fixture changes to complete the machining of one hammer, increasing fixture costs and reducing machining efficiency. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a processing device for drilling rivet holes in piano hammers, which is used to automatically drill holes in piano hammers. The technical solution of this utility model is as follows: A machining device for drilling rivet holes with a hammer, comprising: an input mechanism, a drilling mechanism, and an output mechanism; The input mechanism includes a first guide rail, a first pushing device, and a first transfer device. The first pushing device is slidably disposed on the first guide rail, and the first transfer device is disposed on one side of the output end of the first guide rail. The drilling mechanism includes a second clamping assembly and a drilling rig. The second clamping assembly is disposed on one side of the first transfer device, and the drilling rig is disposed above the second clamping assembly. The output mechanism includes a second transfer device, a second guide rail, and a second pusher device. The second guide rail is disposed on one side of the second clamping assembly, the second transfer device is located between the second clamping assembly and the second guide rail, and the second pusher device is disposed on the input end of the second guide rail.

[0007] Furthermore, the first transfer device includes a linear drive device and a first clamping assembly, the first clamping assembly being disposed on the linear drive device, and the first clamping assembly clamping the hammer from top to bottom.

[0008] Furthermore, the input mechanism also includes an abutment block, which is disposed on the side of the first transfer device away from the first guide rail, and the distance between the abutment block and the first guide rail is less than the width of two hammers.

[0009] Furthermore, the input mechanism also includes a pressing device, which is disposed above the output end of the first guide rail and is used to press the second-positioned hammers onto the first guide rail.

[0010] Furthermore, the second clamping assembly includes a clamping cylinder and two clamping blocks. The two clamping blocks are arranged opposite each other and drivenly connected to the clamping cylinder. The center point of the clamping cylinder and the center point of the drilling rig are on the same vertical plane. The clamping cylinder drives the two clamping blocks to move towards each other toward the vertical plane where the center point of the clamping cylinder is located.

[0011] Furthermore, the second transfer device includes a two-axis drive assembly and a third clamping assembly, wherein the third clamping assembly and the two-axis drive assembly are drivenly connected.

[0018] like Figure 1-2 As shown, this embodiment provides a processing device for drilling rivet holes with a hammer, including: an input mechanism 1, a drilling mechanism 2, and an output mechanism 3; The input mechanism 1 includes a first guide rail 11, a first pushing device 12, and a first transfer device 13. The first guide rail 11 extends in the left-right direction. The first pushing device 12 is slidably disposed on the first guide rail 11. The first transfer device 13 is disposed on one side of the output end of the first guide rail 11 (the right side of the first guide rail 11). Hammers are arranged on the first guide rail 11. The first pushing device 12 pushes the hammers one by one into the first transfer device 13. The first transfer device 13 drives forward to move the hammers into the drilling mechanism 2. The drilling mechanism 2 includes a second clamping assembly 21 and a drilling machine 22. The second clamping assembly 21 is disposed in front of the first transfer device 13, and the drilling machine 22 is disposed above the second clamping assembly 21. The second clamping assembly 21 receives the hammer from the first transfer device 13 and clamps it, and the drilling machine 22 processes the hammer. The output mechanism 3 includes a second transfer device 31, a second guide rail 32, and a second pusher device 33. The second guide rail 32 is located on the right side of the second clamping assembly 21 and extends in the left-right direction. The second transfer device 31 is located between the second clamping assembly 21 and the second guide rail 32. The second pusher device 33 is located on the input end of the second guide rail 32. The second transfer device 31 transfers the processed hammer from the drill second clamping assembly 21 to the second guide rail 32, and the second pusher device 33 pushes the hammer to move along the second guide rail 32 to output the hammer.

[0019] The automated processing of the hammers is achieved through the cooperation of the input mechanism 1, the drilling mechanism 2 and the output mechanism 3. The hammers are input and output in rows in batches, which facilitates the placement of the hammers during subsequent transportation.

[0020] like Figure 3-4 As shown, in a preferred embodiment, the first transfer device 13 includes a linear drive device 131 and a first clamping assembly 132. The first clamping assembly 132 is disposed on the linear drive device 131. The linear drive device 131 drives the first clamping assembly 132 in the front-back direction. The first clamping assembly 132 clamps the hammer from top to bottom. After receiving the hammer, the first clamping assembly 132 clamps it tightly, and then passes it through the linear drive device 131 to the second clamping assembly 21.

[0021] Furthermore, the first clamping assembly 132 includes a support block, a first pressing block, and a first pressing cylinder. The support block is disposed on the right side of the first guide rail 11 and is flush with the first guide rail 11, so that the hammer can be moved from the first guide rail 11 to the support block. The first pressing block is located above the support block and is drivenly connected to the first pressing cylinder. The first pressing cylinder drives the first pressing block to press down, so as to press the hammer tightly onto the support block.

[0022] Preferably, the linear drive device 131 is a drive assembly consisting of a cylinder and a slide rail.

[0023] like Figure 2-3 As shown, the input mechanism 1 further includes an abutment block 14, which is disposed on the side of the support block away from the first guide rail 11. The distance between the abutment block 14 and the first guide rail 11 is less than the width of the two hammers. This ensures that the pushed-out hammers can rest on the support block without falling off.

[0024] like Figure 2-3 As shown, the input mechanism 1 further includes a pressing device 15, which is disposed above the output end of the first guide rail 11 and is used to press the second-position hammer onto the first guide rail 11 (the first-position hammer is the hammer that has been pushed onto the first clamping assembly 132) to prevent the first transfer device 13 from interfering with the second-position and subsequent hammers when it moves.

[0025] Specifically, the pressing device 15 includes a second pressing cylinder and a second pressing block. The second pressing cylinder is located above the output end of the first guide rail 11, and the second pressing block is located at the output end of the second pressing cylinder.

[0026] Furthermore, the first pushing device 12 includes a linear motor and a first pushing block, the first pushing block being slidably disposed on the first guide rail 11 and being drivenly connected to the linear motor.

[0027] like Figure 2-4 As shown, in a preferred embodiment, the second clamping assembly 21 includes a clamping cylinder and two clamping blocks. The two clamping blocks are arranged opposite each other and drivenly connected to the clamping cylinder. The center point of the clamping cylinder and the center point of the drilling rig 22 are on the same vertical plane. The clamping cylinder drives the two clamping blocks to move towards each other on the vertical plane where the center point of the clamping cylinder is located, so as to clamp the hammer. This ensures that the center of the hammer and the center of the drilling rig 22 are also on the same vertical plane, achieving positioning in the left and right directions (the clamping cylinder is fixed to form a reference in the front and back directions, and the front and back positioning is completed when the first transfer device 13 drives the hammer to abut against the clamping cylinder).

[0028] like Figure 2-3 As shown, in a preferred embodiment, the second transfer device 31 includes a two-axis drive assembly 311 and a third clamping assembly 312. The third clamping assembly 312 and the two-axis drive assembly 311 are drivenly connected. The two-axis drive assembly 311 is used to drive the third clamping assembly 312 to move in both the up-down and left-right directions.

[0029] Preferably, the dual-axis drive assembly 311 is a combined drive consisting of a cylinder and slide rail assembly (for left-right driving) and a lifting cylinder assembly (for up-down driving).

[0030] Preferably, the third clamping component 312 has the same structure as the second clamping component 21. For example... Figure 4 As shown, in a preferred embodiment, the second pushing device 33 includes a flat-push cylinder and a second push block. The second push block and the flat-push cylinder are driven together. The flat-push cylinder drives the second push block to push the hammers along the output end of the second guide rail 32. The pushing distance is greater than the width of one hammer. The hammers arranged in front continue to move forward under the transmission of the hammers behind.

[0031] To prevent interference between the first, second, and third clamping components, the first clamping component 132 clamps the tail of the hammer, the second clamping component 21 clamps the head of the hammer, and the third clamping component 312 clamps the tail of the hammer.

[0032] like Figure 3 As shown, the input mechanism 1 further includes a telescopic block 16, which is movably disposed below the abutment block 14. The telescopic block 16 is connected to a cylinder and can extend to the gap between the abutment block 14 and the first guide rail 11 to support the head of the hammer. Specifically, before the first clamping assembly 132 clamps the hammer, the telescopic block 16 extends and supports the hammer together with the support block. It retracts after the first clamping assembly 132 clamps the hammer.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
