Description

Technical Field

[0001] The invention belongs to a mechanical processing technology and relates to a small copper shell deburring device and a method thereof. Background Art

[0002] When a small thin-walled copper shell product is being machined, burrs will be generated at the connection between the outer circle and the end face. Since the product size is only φ5.9×3.4mm, and the wall is thin and easy to deform. The existing machinery is either complex in structure and requires multiple operations to remove the burrs, or the deburring effect is not ideal. Therefore, at present, the deburring of small copper shells is mostly done by manual grinding and deburring, which is inconvenient to operate, labor-intensive, and very low in production efficiency. And because the manual grinding operations of different operators are different, the appearance quality and consistency of the deburred product are poor, which is difficult to meet product requirements. In response to the above problems, a small copper shell deburring device is designed. Compared with the original method, the products processed by the device have high appearance quality and good consistency of deburred products. The device has a simple structure, high safety, and easy operation. It realizes semi-automatic processing and increases production efficiency by 20 times. Summary of the invention

A method for deburring a small copper shell, using a small copper shell deburring device as claimed in any one of claims 1 to 7 to remove burrs, characterized in that: The method comprises the following steps: The handle (29) is operated to swing up and down with the connection point of the connecting plate (1) as the center, and the large slide seat (5) and the machine head (34) and the hand drill (30) fixedly connected thereto are driven to reciprocate up and down along the guide column (3) through the connecting rod (28); When the hand drill (30) moves downward, the switch contacts the trigger rod (31), so that the hand drill (30) is started, driving the main shaft (35) to rotate. When the hand drill (30) moves upward, the switch disengages from the trigger rod (31), so that the hand drill (30) is turned off, and the main shaft (35) stops rotating. The support shaft (38) and the bearing III (37) and the thrust bearing (39) form a bearing group structure, which can rotate freely under the action of external force; The material is fed, and the mouth of the small copper shell is fed upward into the material tray (8), and the small copper shell slides down along the material tray (8) outlet onto the support shaft (38). When the main shaft (35) moves downward with the random head (34), the small copper shell is just inserted, and the small copper shell is clamped together with the support shaft (38). When the hand electric drill (30) is started, the small copper shell is driven to rotate, and the burrs are removed by turning with the white steel blade (27) using the lathe principle.

9. The method according to claim 1, characterized in that: Also includes: The knife seat (16), the knife bar (21) and the bearing I (10) form a bearing group structure. The white steel knife strip (27) installed on the knife bar (21) can swing within a certain range under the restriction of the limit screw (24) and the adjustment spring (20). The limit screw (24) is turned to adjust the contact point position between the limit screw (24) and the knife bar (21) so that the contact position between the tip of the white steel knife strip (27) and the small copper shell meets the deburring requirement, and the burrs are waiting to be 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 bar (21), so that the tip of the white steel blade (27) on the tool bar (21) continuously applies a cutting force to the small copper shell, and when the small copper shell rotates with the main shaft (35), the burrs are removed by turning.

10. The method according to claim 9, characterized in that Also includes: The cam (25) mounted on the large slide (5) reciprocates 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) is 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. The cam (25) moves upward, and the unloading rod (17) slides rightward, so that the opening just half surrounds the main shaft (35). The main shaft (35) continues to move upward with the large slide (5), and the small copper shell sleeved on the end of the main shaft (35) is scraped off by the unloading rod (17), so that unloading is realized; 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 twisting the top screw (26).
