Description

Technical Field

[0001] This invention pertains to a type of machining technology, specifically a deburring device and method for small copper shells. Background Technology

[0002] When machining a small, thin-walled copper shell product, burrs are generated at the connection between the outer diameter and the end face. Because the product size is only φ5.9×3.4mm, and the wall is thin and easily deformed, existing machinery is either complex, requiring multiple operations to remove burrs, or the deburring effect is unsatisfactory. Therefore, currently, deburring of small copper shells is mostly done manually, which is inconvenient, labor-intensive, and has very low production efficiency. Furthermore, due to variations in manual grinding operations by different operators, the appearance quality and consistency of the deburred product are poor, making it difficult to meet product requirements. To address these problems, a deburring device for small copper shells is designed. Compared with the original method, the products processed by this device have higher appearance quality and better consistency after deburring. The device has a simple structure, high safety, and convenient operation, achieving semi-automatic processing and increasing production efficiency by 20 times. Summary of the Invention

[0003] The technical problem of this invention is:

[0004] Existing deburring machines are either complex in design, requiring multiple operations to remove burrs, or their deburring effect is unsatisfactory. Therefore, currently, deburring of small copper casings is mostly done manually, which is inconvenient, labor-intensive, and extremely inefficient. Furthermore, due to variations in manual grinding techniques among different operators, the appearance quality and consistency of the deburred products are poor, making it difficult to meet product requirements.

[0005] The technical solution of this invention is:

[0006] On one hand, the present invention proposes a deburring device for small copper shells. The device includes a connecting plate 1, a large tension spring 2, a guide post 3, a connecting bracket 4, a large slide 5, a small tension spring 6, a material tray 7, a material tray seat 8, a base 9, a bearing I 10, a cutter holder 11, a support 12, a pressure plate 13, a small slide 14, a compression spring 15, a cutter holder 16, a discharge rod 17, an adjusting screw 18, a roller 19, an adjusting spring 20, a cutter bar 21, a pressure plate 22, a limit seat 23, a limit screw 24, a cam 25, a set screw 26, a stainless steel cutter bar 27, a connecting rod 28, a handle 29, a hand drill 30, a trigger rod 31, an end cover 32, a bearing II 33, a machine head 34, a main shaft 35, a cover plate 36, a bearing III 37, a support shaft 38, a thrust bearing 39, a base 40, and a shim 41. The guide post 3 is installed on the base 9, and the connecting plate 1 is fixedly connected to the guide post 3. The large slide 5 is installed on the guide post 3, between the base 9 and the connecting plate 1, and is connected to the connecting plate 1 through the large tension spring 2, the connecting rod 28, and the handle 29. The spindle 35 is installed inside the head 34 through the end cover 32 and the bearing II 33. The head 34 is fixedly connected to the large slide 5. The electric drill 30 is fixedly connected to the large slide 5 through the connecting bracket 4 and connected to the spindle 35. The trigger rod 31 is installed on the base 9, and its axis is switched through the electric drill 30.

[0007] Manually operate the handle 29, causing it to swing up and down around the connection point of the connecting plate 1. This, via the connecting rod 28, drives the large slide 5 and the fixedly connected machine head 34 and electric drill 30 to reciprocate up and down along the guide post 3. When the electric drill 30 moves downward, the switch contacts the trigger rod 31, starting the electric drill 30 and causing the spindle 35 to rotate. When the electric drill 30 moves upward, the switch disengages from the trigger rod 31, turning off the electric drill 30 and stopping the spindle 35 from rotating. The support shaft 38 is installed inside the base 40 via the cover plate 36, bearing III 37, and thrust bearing 39. The base 40 is fixedly connected to the base 9 via the shim 41 and the material tray 7 via the material tray seat 8. The material tray 7's outlet is suspended above the support shaft 38. The feature is that the support shaft 38, bearing Ⅲ 37, and thrust bearing 39 form a bearing assembly structure, which can rotate freely under the action of external force; manual feeding, the small copper shell is fed upward into the material tray 8, and slides down along the material tray 8 to the support shaft 38. When the main shaft 35 moves downward with the head 34, it just inserts into the small copper shell and clamps the small copper shell together with the support shaft 38. When the electric drill 30 is started, it drives the small copper shell to rotate. Using the lathe principle, the burrs are removed by turning with the white steel cutter 27. The tool holder 16 is mounted inside the tool holder 11 via bearing I 10. The tool holder 11 is fixedly connected to the base 9 via shim 41. The tool 21 is fixedly connected to the tool holder 16 via pressure plate 22. The stainless steel blade 27 is mounted inside the tool 21, with the blade tip contacting the small copper shell burr on the support shaft 38. The pressure plate 13 is fixedly connected to the shim 41. The adjusting spring 20 is mounted on the pressure plate 13 via adjusting screw 18 and contacts the tool 21. The limiting screw 24 is mounted on the base 40 via limiting seat 23 and contacts the tool 21. The feature is that: the tool holder 16, the tool shank 21 and the bearing I 10 form a bearing assembly structure; the stainless steel blade 27 mounted on the tool shank 21 can swing within a certain range under the restriction of the limiting screw 24 and the adjusting spring 20; the limiting screw 24 is turned to adjust the contact point between the limiting screw 24 and the tool shank 21 so that the contact position between the tip of the stainless steel blade 27 and the small copper shell meets the deburring requirements, and the burr is removed by turning; the adjusting screw 18 is turned to adjust the compression state of the adjusting spring 20, and a certain pressure is applied to the tool shank 21 so that the tip of the stainless steel blade 27 on the tool shank 21 continuously applies cutting force to the small copper shell, and the burr is removed by turning when the small copper shell rotates with the spindle 35. The cam 25 is mounted on the large slide block 5 via the set screw 26. The support 12 is fixedly connected to the base 9. The legs of the small slide block 14 are inserted into the support 12. The compression spring 15 passes through the legs of the small slide block 14 and is located between the small slide block 14 and the support 12. The unloading rod 17 is installed inside the small slide block 14 and is connected to the small slide block 14 via the small tension spring 6. The roller 19 is installed on the unloading rod 17 and contacts the cam 25.The feature is that: the cam 25 installed on the large slide 5 moves up and down with the large slide 5, and pushes the unloading rod 17 to slide left and right in the horizontal direction through the roller 19. The head of the unloading rod 17 has an open structure, and the opening size is between the outer diameter of the main shaft 35 and the outer diameter of the small copper shell. When the cam 25 moves upward, the unloading rod 17 slides to the right, so that the opening just partially surrounds the main shaft 35. The main shaft 35 continues to move upward with the large slide 5, and the small copper shell sleeved at the end of the main shaft 35 is scraped off by the unloading rod 17 to achieve unloading. The relative position of the opening of the unloading rod 17 and the main shaft 35 is adjusted by adjusting the left and right position of the cam 25, and the up and down position of the unloading rod 17 is adjusted by turning the set screw 26.

[0008] Preferably, the spindle 35 is operated by the manual handle 29, which drives the large slide 5 and the machine head 34 and electric drill 30 fixedly connected thereto to move up and down along the guide post 3 via the connecting rod 28.

[0009] Preferably, during the reciprocating motion of the electric drill 30, the drill 30 is started and stopped by the trigger rod 31 touching and disengaging the switch of the electric drill 30, thereby driving the spindle 35 to rotate and stop.

[0010] Preferably, the small copper shell is held by the main shaft 35 and the support shaft 38, and rotated by the electric drill 30, and the burrs are removed by turning with the high-speed steel blade 27.

[0011] Preferably, the support shaft 38, bearing Ⅲ 37, and thrust bearing 39 form a bearing assembly structure, which can rotate freely to avoid relative rotation with the small copper shell and damage to the product.

[0012] Preferably, the stainless steel blade 27 mounted on the blade holder 21 can swing freely by forming a bearing assembly structure with the blade holder 16, the blade holder 21 and the bearing I 10.

[0013] Preferably, the swing range of the stainless steel blade 27 is controlled by the limiting screw 24 and the adjusting spring 20. The contact position between the blade tip of the stainless steel blade 27 and the small copper shell is adjusted by turning the limiting screw 24. The cutting force continuously applied by the blade tip to the small copper shell is adjusted by turning the adjusting screw 18 to adjust the compression state of the adjusting spring 20 and change the pressure applied to the blade shank 21.

[0014] Preferably, the unloading rod 17 slides left and right in the horizontal direction via the cam 25 and the roller 19. When the cam 25 moves to the upper stop position, the opening of the unloading rod 17 just partially surrounds the main shaft 35, scraping off the small copper shell that moves upward and is fitted at the end of the main shaft 35, thereby realizing automatic unloading.

[0015] Preferably, the relative position of the opening of the unloading rod 17 and the main shaft 35 is adjusted by adjusting the left and right positions of the cam 25.

[0016] Preferably, the unloading rod 17 is positioned to scrape small copper shells, and its vertical position can be adjusted by turning the set screw 26.

[0017] On the other hand, the present invention proposes a method for deburring small copper shells, which uses the above-mentioned small copper shell deburring device to remove burrs. The method includes the following steps:

[0018] Operate handle 29 to swing up and down around the connection point of connecting plate 1, and drive large slide 5 and machine head 34 and electric drill 30 fixedly connected to it to move up and down along guide post 3 via connecting rod 28;

[0019] When the electric drill 30 moves downward, the switch contacts the trigger rod 31, starting the electric drill 30 and causing the spindle 35 to rotate. When the electric drill 30 moves upward, the switch disengages from the trigger rod 31, turning off the electric drill 30 and stopping the spindle 35 from rotating. The support shaft 38, bearing Ⅲ 37, and thrust bearing 39 form a bearing assembly structure, which can rotate freely under external force.

[0020] Feeding: The small copper shell is fed upward into the material tray 8 and slides down the material tray 8 to the support shaft 38. When the spindle 35 moves downward along the head 34, it is inserted into the small copper shell and clamped together with the support shaft 38. When the electric drill 30 is started, it drives the small copper shell to rotate. Using the lathe principle, the burrs are removed by turning with the white steel cutter 27.

[0021] The advantages and beneficial effects of this invention are:

[0022] This invention achieves deburring by designing a transmission system, spindle structure, and cutting tool mechanism in conjunction with an electric drill. The device is characterized by its compact structure, simple operation, and high safety due to the manual feeding position being far from the deburring station. It also features automatic processing and automatic unloading functions, realizing semi-automatic processing of small copper shells.

The guide post 3 is installed on the base 9, and the connecting plate 1 is fixedly connected to the guide post 3. The large slide 5 is installed on the guide post 3, between the base 9 and the connecting plate 1, and is connected to the connecting plate 1 through the large tension spring 2, the connecting rod 28, and the handle 29. The main shaft 35 is installed inside the machine head 34 through the end cover 32 and the bearing II 33. The machine head 34 is fixedly connected to the large slide 5. The electric drill 30 is fixedly connected to the large slide 5 through the connecting bracket 4 and is connected to the main shaft 35. The trigger rod 31 is installed on the base 9, and its axis is switched by the electric drill 30. The support shaft 38 is installed inside the base 40 through the cover plate 36, the bearing III 37, and the thrust bearing 39. The base 40 is fixedly connected to the base 9 through the pad 41 and the material tray 7 through the material tray seat 8. The material tray 7 outlet is suspended above the support shaft 38. The tool holder 16 is mounted inside the tool holder 11 via bearing I 10. The tool holder 11 is fixedly connected to the base 9 via shim 41. The tool 21 is fixedly connected to the tool holder 16 via pressure plate 22. The stainless steel blade 27 is mounted inside the tool 21, with the blade tip contacting the small copper shell burr on the support shaft 38. The pressure plate 13 is fixedly connected to the shim 41. The adjusting spring 20 is mounted on the pressure plate 13 via adjusting screw 18 and contacts the tool 21. The limiting screw 24 is mounted on the base 40 via limiting seat 23 and contacts the tool 21. The cam 25 is mounted on the large slide block 5 via the set screw 26. The support 12 is fixedly connected to the base 9. The legs of the small slide block 14 are inserted into the support 12.

The unloading rod 17 is installed inside the small slide block 14 and is connected to the small slide block 14 via the small tension spring 6. The roller 19 is installed on the unloading rod 17 and contacts the cam 25.

[0036] The working process of this small copper shell deburring device is as follows:

[0037] Manually operate the handle 29 to swing it up and down around the connection point of the connecting plate 1. This causes the large slide 5 and the machine head 34 and the electric drill 30, which are fixedly connected to it, to move up and down along the guide post 3 via the connecting rod 28. When the electric drill 30 moves downward, the switch contacts the trigger rod 31, starting the electric drill 30 and causing the spindle 35 to rotate. When the electric drill 30 moves upward, the switch disengages from the trigger rod 31, turning off the electric drill 30 and stopping the spindle 35 from rotating. The support shaft 38, bearing Ⅲ 37, and thrust bearing 39 form a bearing assembly structure, which can rotate freely under the action of external force. When manually feeding, the small copper shell is fed upward into the material tray 8 and slides down the material tray 8 to the support shaft 38. When the spindle 35 moves downward along the head 34, it is inserted into the small copper shell and clamps the small copper shell together with the support shaft 38. When the electric drill 30 is started, it drives the small copper shell to rotate. Using the lathe principle, the burrs are removed by turning with the white steel cutter 27. The tool holder 16, tool shank 21, and bearing I 10 form a bearing assembly structure. The stainless steel blade 27 mounted on the tool shank 21 can swing within a certain range under the restriction of the limit screw 24 and the adjusting spring 20. Tighten the limit screw 24 to adjust the contact point between the limit screw 24 and the tool shank 21 so that the contact position between the tip of the stainless steel blade 27 and the small copper shell meets the deburring requirements, and wait for the burr to be removed by turning. Tighten the adjusting screw 18 to adjust the compression state of the adjusting spring 20, and apply a certain pressure to the tool shank 21 so that the tip of the stainless steel blade 27 on the tool shank 21 continuously applies cutting force to the small copper shell. When the small copper shell rotates with the spindle 35, the burr is removed by turning. The cam 25, mounted on the large slide block 5, moves up and down with the large slide block 5, and pushes the unloading rod 17 to slide horizontally left and right through the roller 19. The head of the unloading rod 17 has an open structure, and the opening size is between the outer diameter of the main shaft 35 and the outer diameter of the small copper shell. When the cam 25 moves upward, the unloading rod 17 slides to the right, so that the opening is exactly half-encircling the main shaft 35. The main shaft 35 continues to move upward with the large slide block 5, and the small copper shell fitted at the end of the main shaft 35 is scraped off by the unloading rod 17, thus achieving unloading. The relative position of the opening of the unloading rod 17 and the main shaft 35 is adjusted by adjusting the left and right position of the cam 25, and the up and down position of the unloading rod 17 is adjusted by turning the set screw 26.

[0038] This invention achieves deburring by designing a transmission system, spindle structure, cutting tool mechanism, and other mechanisms to work in conjunction with an electric drill. The device is characterized by its compact structure, simple operation, and high safety due to the manual feeding position being far from the deburring station. It also features automatic processing and automatic unloading functions, realizing semi-automatic processing of small copper shells. Compared with manual deburring, the production efficiency is increased by 20 times, and the deburred appearance quality is high and consistent.

[0039] It should be noted that the above process operations can be combined to varying degrees. For the sake of brevity, the implementation methods of various combinations will not be elaborated here. Those skilled in the art can flexibly adjust the order of the above operation steps or flexibly combine the above steps according to actual needs.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be covered within the protection scope of the present invention.
