Description

Technical Field

[0001] This invention relates to the field of drilling technology, and more specifically, to a drilling apparatus for digital camera accessories. Background Technology

[0002] With the rapid improvement of living standards in China, people often take photos when traveling or gathering with friends. Although mobile phones are convenient, digital cameras are undoubtedly the best choice if you want to take high-quality photos.

[0003] Digital cameras require motion control for functions such as focus adjustment, shutter speed control, and exposure compensation. Therefore, a motor is installed inside the camera. Since the motor is relatively far from the actuators, a transmission gear is used for transmission. The transmission gear is one of the key components in the camera; it is connected to camera components such as the focal plane shutter, lens, and shutter speed selector to achieve various functions.

[0004] Gear transmission requires a U-shaped support component with holes drilled on both sides to support the transmission shaft. This U-shaped support component is generally formed by bending. Due to the difficulty in controlling the bending precision, it is impossible to ensure that the holes on both sides are aligned. Therefore, it is usually processed by bending first and then drilling to ensure that the holes are aligned. Since two holes need to be drilled, after drilling the first hole, it needs to be flipped before drilling the second hole. In the existing technology, to avoid the flipping structure, a support block is used to support the U-shaped support component in the middle during drilling. A hole is made in the middle of the support block. In this way, when drilling, after the drill bit drills the hole on one side of the U-shaped support component, it directly passes through the hole on the support block to drill the hole on the other side of the U-shaped support component.

[0005] However, since the U-shaped bracket is bent before drilling, it is difficult to ensure that the two sides of the U-shaped bracket are completely parallel during bending. If the two sides of the U-shaped bracket are spread outward (i.e., the angle between the two side walls and the middle is greater than 90 degrees), a gap will appear between the side walls of the U-shaped bracket and the support block. During the drilling process, the side walls of the U-shaped bracket will vibrate with a large amplitude. This vibration will cause the drilled hole to be out of round and the surrounding material to deform. The spindle will shake when installed in the hole and will vibrate during transmission. Summary of the Invention

[0006] The present invention provides a drilling processing device for digital camera accessories. The problem to be solved is that when the two sides of the U-shaped bracket accessory open outward, a gap will appear between the side wall of the U-shaped bracket accessory and the support block. During the drilling process, the side wall of the U-shaped bracket accessory will vibrate with a large amplitude, resulting in the drilled hole being out of round and the surrounding material deforming.

The two ends of the push plate are respectively opposite to the second inclined surface on the two limiting posts. The push plate pushes the second inclined surface to bring the two limiting posts closer to each other.

[0011] In a preferred embodiment, guide plates are fixedly connected to both sides of the mounting base near the support component. The front end of the guide plate is inclined outward and is used to push the push plate to move, thereby pushing the two limiting posts closer to each other.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Refer to the instruction manual appendix Figures 1-11 A drilling processing device for digital camera accessories includes a worktable 1, on which a drilling assembly 11 is installed; A table 2 is installed on the workbench 1, and a support component 3 is installed on the table 2. The support component 3 includes a base 31, and a support seat 32 is installed on the upper end of the base 31. The support seat 32 is an open-end shape and is used to support the bracket accessory 100. Through holes 33 are provided on both the upper and lower sides of the support seat 32. The two through holes 33 are set opposite each other. The drilling component 11 drills mounting holes 101 from the through holes 33 into the bracket accessory 100. A power assembly 5 is provided on one side of the platform 2, which is located on the support assembly 3. The power assembly 5 includes a mounting base 51, which is mounted on the platform 2. A linear drive component 52 is mounted on the mounting base 51. A support assembly 4 is fixedly mounted on the output end of the linear drive component 52. The support assembly 4 includes a support block 41. The linear drive component 52 is used to drive the support block 41 to insert the support block 41 into the interior of the support base 32, so that the bracket accessory 100 is held between the support base 32 and the support block 41. The support block 41 has a vertically arranged clearance hole 411. After the support block 41 is inserted into the bearing seat 32, the clearance hole 411 is directly opposite to the two through holes 33.

[0032] In the above technical solution, a column 12 is installed on the workbench 1, and an installation rail 13 is vertically slidably installed on the column 12. A rotary drive component 14 is also installed at the upper end of the column 12. A lead screw 15 is fixedly connected to the output end of the rotary drive component 14. The lead screw 15 is threadedly connected to the installation rail 13. The drilling assembly 11 is installed on the installation rail 13.

[0033] It should be noted that the drilling assembly 11 includes a motor, a gearbox, and a drill bit. The power of the motor is transmitted to the drill bit through the gearbox. The rotary drive component 14 adopts a geared motor. The lead screw 15 is set vertically. The geared motor drives the lead screw 15 to rotate, which in turn drives the mounting rail 13 to move vertically. When the mounting rail 13 drives the drilling assembly 11 to move downward, the bracket accessory 100 can be drilled out of the mounting hole 101.

[0034] like Figure 4 and Figure 5 As shown, in the above technical solution, the linear drive component 52 is a cylinder, and the support block 41 is fixedly installed on the movable end of the linear drive component 52, and the support block 41 is moved by the linear drive component 52.

[0035] In this embodiment, the specific implementation method is as follows: Figure 5 As shown, the workpiece is a U-shaped bracket accessory 100. Mounting holes 101 need to be drilled on both the upper and lower side walls of the bracket accessory 100. When drilling, as... Figure 5As shown, the bracket accessory 100 needs to be fitted onto the support block 41 first. The opening of the bracket accessory 100 faces one side of the support block 41, and the two side walls of the bracket accessory 100 are located at the upper and lower surfaces of the support block 41, respectively. Then, the linear drive component 52 drives the support block 41 to move towards the bearing seat 32, so that the support block 41 is inserted into the interior of the bearing seat 32, and the upper wall of the bracket accessory 100 is in contact with the upper wall of the bearing seat 32, and the lower wall of the bracket accessory 100 is in contact with the lower wall of the bearing seat 32. Thus, through the constraint of the support block 41 and the bearing seat 32, even if the two sides of the bracket accessory 100 are spread outward (i.e., the angle between the two side walls and the middle is greater than 90 degrees), the two side walls of the bracket accessory 100 can be kept horizontal by the constraint and clamping of the bearing seat 32 and the support block 41. There are no gaps between the upper and lower walls of the bracket accessory 100 and the support block 41, and between the upper and lower walls of the bracket accessory 100 and the bearing seat 32. Thus, during drilling, it is ensured that the bracket accessory 100 will not vibrate with large amplitude, and the drilled bracket accessory 100 is relatively round and the material around the bracket accessory 100 will not deform, ensuring the stability of the camera drive spindle during use.

[0036] It should be noted that during the drilling process, the drill bit of the drilling assembly 11 passes through the through hole 33 and drills downwards. After drilling out the mounting hole 101 on the upper side wall of the bracket accessory 100, the drill bit continues to move downwards, passes through the clearance hole 411, and drills out the mounting hole 101 on the lower side wall of the bracket accessory 100. A discharge groove 311 is opened on the base 31, and some drilling debris can be discharged at the location of the discharge groove 311.

[0037] Refer to the instruction manual appendix Figures 5-6 After the bracket accessory 100 is fitted onto the support block 41, when the support block 41 is inserted into the bearing seat 32, the position of the bracket accessory 100 may shift to both sides of the bearing seat 32. Therefore, in order to drill smoothly, the through hole 33 and the clearance hole 411 need to be set to be relatively large. Moreover, during the drilling process, the drilling position of the drilling assembly 11 also needs to be adjusted, which is quite troublesome. If the through hole 33 and the clearance hole 411 are set to be relatively large, then at the position of the through hole 33 and the clearance hole 411, a considerable portion of the material at the drilling position on the side wall of the bracket accessory 100 will not be supported and clamped by the bearing seat 32 and the support block 41. During drilling, in addition to the material that is drilled out, the other unsupported material will vibrate, causing deformation around the hole. Therefore, before drilling, the clamping position of the bracket accessory 100 needs to be adjusted. Specifically, the upper wall, lower wall and side wall of the inner side of the bearing seat 32 are provided with guide grooves 34. The guide grooves 34 are located at the front end of the upper wall and lower wall of the bearing seat 32 and have expansion parts 35. The expansion parts 35 are set with openings.

[0038] It should be noted that before drilling, the bracket accessory 100 is fitted onto the support block 41, and then the support block 41 is inserted into the bearing seat 32 by the linear drive component 52. During insertion, the bracket accessory 100 is guided into the guide groove 34 through the expansion part 35, so that the edges on both sides of the bracket accessory 100 fit against the sides of the guide groove 34. This can limit the position of the bracket accessory 100, so that the position of the bracket accessory 100 is fixed each time drilling. Therefore, it is not necessary to adjust the drilling position of the drilling assembly 11 during drilling, nor is it necessary to set the through hole 33 and the clearance hole 411 to be too large. It is only necessary to make them consistent with the diameter of the mounting hole 101, so as to prevent the problem of vibration of the unsupported material during drilling caused by the hole being too large.

[0039] Refer to the instruction manual appendix Figures 3-9 After drilling is completed, the linear drive component 52 drives the support block 41 to move out of the bearing seat 32. Since the clamping force between the bracket accessory 100 and the support block 41 is uncertain, the bracket accessory 100 may move out of the bearing seat 32 together with the support block 41, or the bracket accessory 100 may detach from the support block 41 and remain inside the bearing seat 32. In order to determine the position of the bracket accessory 100, specifically, the support block 41 is provided with a cavity 42 at the front end of the clearance hole 411. The upper and lower ends of the cavity 42 are movably inserted with limit posts 43. The upper end of the limit post 43 has an inclined surface 430 on the side away from the clearance hole 411. An elastic component 44 is provided between the two limit posts 43. The two ends of the elastic component 44 are respectively pressed against the two limit posts 43. The two sides of the cavity 42 are provided with components for driving the two limit posts 43 to move closer to each other.

[0040] Furthermore, the component used to drive the two limiting posts 43 to move closer to each other is a push plate 45. A limiting plate 46 is installed on the side wall of the support block 41. The push plate 45 is laterally movably inserted into the limiting plate 46. Both sides of the limiting post 43 have inclined surfaces 431. The two ends of the push plate 45 are respectively opposite to the inclined surfaces 431 on the two limiting posts 43. The push plate 45 pushes the inclined surfaces 431 to bring the two limiting posts 43 closer to each other.

[0041] It should be noted that the elastic component 44 is a compression spring, such as... Figure 9 As shown in (1), when the bracket accessory 100 is not fitted onto the support block 41, the two limiting posts 43 are pressed to both sides by the elastic member 44, so that the ends of the two limiting posts 43 protrude from the upper and lower walls of the support block 41, respectively. When the bracket accessory 100 is fitted onto the support block 41 from its end position, as shown in (1), Figure 9As shown in (2), the bracket accessory 100 will push the inclined plane 430, causing the two limiting posts 43 to move into the cavity 42. After the mounting hole 101 is drilled in the bracket accessory 100, the support block 41 moves to the outside of the bearing seat 32. At this time, if the bracket accessory 100 can move together with the support block 41, then the relative positional relationship between the limiting posts 43 and the bracket accessory 100 is as follows: Figure 9 As shown in (2), if the bracket accessory 100 does not move with the support block 41, then during the movement of the support block 41, when the limiting post 43 moves to the position of the mounting hole 101, as shown in (2), Figure 9 At the position shown in (3), under the action of the elastic member 44, the limiting post 43 will extend and insert into the interior of the mounting hole 101. At this time, under the limiting action of the limiting post 43, the bracket accessory 100 will move outward together with the support block 41. When it is necessary to remove the bracket accessory 100 from the support block 41, the two push plates 45 are pressed towards the center. The two push plates 45 push the inclined plane 431 to make the two limiting posts 43 move closer to each other, as shown in (3). Figure 9 Position the limit post 43 away from the mounting hole 101 as shown in (4), and then the bracket accessory 100 can be removed.

[0042] With the above technical solution, when the bracket accessory 100 does not move out of the bearing seat 32 along with the support block 41, the mounting hole 101 can be forced to move out of the bearing seat 32 by limiting the mounting hole 101 by the limiting post 43. Therefore, it can be ensured that when the support block 41 moves out of the bearing seat 32, the bracket accessory 100 can move out along with the support block 41 each time.

[0043] Furthermore, guide plates 53 are fixedly connected to both sides of the mounting base 51 near the support component 4. The front end of the guide plate 53 is inclined outward. The guide plate 53 is used to push the push plate 45 to move, thereby pushing the two limiting posts 43 closer to each other.

[0044] It should be noted that, as Figure 4 As shown, when the linear drive component 52 moves the support block 41 out of the bearing seat 32, the push plate 45 will first contact the front end of the guide plate 53. The guide plate 53 will push the two push plates 45 to move towards the center, so that the two limit posts 43 will move closer to each other and disengage from the mounting hole 101. Then the bracket accessory 100 can be easily removed.

[0045] Furthermore, in order to automatically remove the bracket accessory 100, specifically, the power assembly 5 also includes a linear drive component 2 54, which is fixedly mounted on the mounting base 51. The output end of the linear drive component 2 54 is equipped with a discharge frame 55, which is sleeved on the outside of the two guide plates 53.

[0046] It should be noted that the linear drive component 2 54 uses a cylinder. When the two limit posts 43 are disengaged from the mounting hole 101, the linear drive component 2 54 drives the discharge frame 55 to move, causing the discharge frame 55 to push the upper and lower ends of the bracket accessory 100, so that the bracket accessory 100 is disengaged from the support block 41.

[0047] Furthermore, the platform 2 has a material drop hole 21 on one side of the supporting component 3, and a discharge hopper 22 is installed at the bottom of the platform 2, with the upper end of the discharge hopper 22 located at the bottom of the material drop hole 21.

[0048] It should be noted that after the discharge frame 55 pushes the bracket accessory 100 away from the support block 41, it will fall from the discharge hole 21 into the discharge hopper 22 and be discharged.

[0049] Refer to the instruction manual appendix Figures 10-11 A conveyor belt 6 is provided on one side of the workbench 1, and a feeding assembly 7 is provided on one side of the conveyor belt 6. A vacuum suction cup 8 is installed at the output end of the feeding assembly 7. The conveyor belt 6 is used to transport the bracket accessories 100. The feeding assembly 7 sends the bracket accessories 100 on the conveyor belt 6 to the front of the bearing assembly 3 through the vacuum suction cup 8.

[0050] Furthermore, the feeding assembly 7 includes a support frame 71, a slide table 72 slidably mounted on the support frame 71, a rotary drive component 73 mounted on the slide table 72, a rack 74 mounted on the support frame 71, a gear 75 mounted on the output end of the rotary drive component 73, the gear 75 meshing with the rack 74, a connecting rod 76 mounted on the slide table 72, and a vacuum suction cup 8 mounted on the connecting rod 76.

[0051] It should be noted that the rotary drive component 73 is a motor. The rotary drive component 73 drives the gear 75 to rotate. The gear 75 meshes with the rack 74, so the slide table 72 can move back and forth on the support frame 71. The conveyor belt 6 conveys the bracket accessory 100. The vacuum suction cup 8 is connected to the vacuum generator. After the vacuum suction cup 8 adsorbs the bracket accessory 100, it sends the bracket accessory 100 to the front of the bearing component 3, so that the opening of the bracket accessory 100 faces the support block 41. The linear drive component 52 drives the support block 41 to insert into the bracket accessory 100, and then drives the bracket accessory 100 to insert into the interior of the bearing seat 32, thus completing the loading.

[0052] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
