Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a device for drilling center holes. Background Technology

[0002] A center hole drilling device is a tooling equipment specifically used for precisely machining center holes on the end faces of shafts, bars, or tubular workpieces. When machining slender shaft parts, the center hole can mate with the center on the tailstock of the machine tool to effectively support the workpiece, prevent it from bending due to cutting forces, and ensure machining accuracy.

[0003] In the prior art, Chinese Patent Application No. CN201110395899.8 discloses a center hole drilling device, including a center hole drilling machine, a lifting device, a material trolley, and a guide rail. The center hole drilling machine is fixed on the lifting device, and the material trolley can slide on the guide rail. It can flexibly perform center hole drilling operations on shaft workpieces of different specifications, and can also conveniently operate on parts without moving the workpiece, thereby improving work efficiency, quality, and applicability.

[0004] Based on the above information, it can be seen that the existing drilling center hole device requires workpiece clamping and feeding. However, in actual use, manual clamping and feeding are generally required, resulting in low overall work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a device for drilling center holes to solve the problem of low efficiency of manual operation mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for a center hole, comprising a support base placed horizontally on the ground, an electrical control box and a power box fixedly mounted on the upper surface of the support base, and a drilling bit fixedly mounted on the output shaft of the power box; a support plate fixedly mounted on the upper right side of the support base, and an mounting plate mounted on the upper surface of the support plate; and a lower clamping block and an upper clamping block for clamping the workpiece body are provided above the mounting plate, both of which have inclined surfaces, achieving automatic positioning using the inclined structures of the upper and lower clamping blocks; both the mounting plate and the upper clamping block are pneumatically controlled; and a protective cover for preventing debris from splashing is fixedly mounted on the side of the power box, preventing debris from scattering during the drilling process using the drilling bit; and a cleaning mechanism is provided inside the protective cover.

[0007] Preferably, a support frame is fixedly installed above the mounting plate, and a clamping cylinder is fixedly installed on the upper surface of the support frame. The upper clamping block is fixedly connected to the clamping cylinder. The clamping cylinder pushes the upper clamping block downward to realize the automatic clamping operation of the workpiece body.

[0008] Preferably, a movable slider is fixedly installed on the lower surface of the mounting plate, and the movable slider is slidably connected to a limiting slide rail fixedly installed on the upper surface of the support plate.

[0009] Preferably, a pushing cylinder is fixedly installed on the upper surface of the support plate, and the pushing cylinder pushes the mounting plate to slide relative to the limiting slide rail. Automatic feeding is achieved by pushing the mounting plate to move through the pushing cylinder. The moving slider below the mounting plate slides relative to the limiting slide rail fixedly installed on the upper surface of the support plate, thereby achieving the purpose of limiting the mounting plate.

[0010] Preferably, the cleaning mechanism includes a cleaning nozzle fixedly installed on the inner wall of the protective cover and a blower pump fixedly installed on the upper surface of the support base.

[0011] Preferably, the blower pump is connected to the cleaning nozzle through a delivery pipe, the support base has a dust collection trough inside, and the position of the dust collection trough corresponds to the position of the protective cover. The support base also has a dust collection hopper corresponding to the dust collection trough fixedly installed inside. The blower pump blows air into the cleaning nozzle through the delivery pipe, and finally uses the airflow from the cleaning nozzle to blow away the debris, causing the debris to fall into the dust collection trough and be collected by the collection hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This drilling center hole device adopts a novel structural design, the specific details of which are as follows: 1. After the workpiece body is placed above the lower clamping block, the upper clamping block is pushed downward by the clamping cylinder to realize the automatic clamping operation of the workpiece body. During the clamping process, the inclined structure of the upper and lower clamping blocks is used to achieve automatic positioning. Then, the mounting plate is pushed and moved by the pushing cylinder to achieve automatic feeding. The overall process has a high degree of automation and improves work efficiency. Furthermore, when the cylinder pushes the mounting plate to move, the sliding block under the mounting plate slides relative to the limiting slide rail fixedly installed on the upper surface of the support plate, thereby achieving the purpose of limiting the mounting plate and preventing position deviation.

[0013] 2. During the drilling process of the workpiece body using a drill bit, the protective cover is used to prevent debris from flying everywhere. Furthermore, the blower pump is turned on to blow air into the cleaning nozzle through the delivery pipe. Finally, the airflow from the cleaning nozzle blows away the debris, causing it to fall into the dust collection trough and be collected by the collection bucket. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1-3To improve processing efficiency, this embodiment provides the following technical solution, specifically: a support base 1 placed horizontally on the ground, an electrical control box 2 and a power box 3 fixedly mounted on the upper surface of the support base 1, and a drilling bit 4 fixedly mounted on the output shaft of the power box 3; a support plate 5 fixedly mounted on the upper right side of the support base 1, and an mounting plate 6 mounted on the upper surface of the support plate 5; and a lower clamping block 8 and an upper clamping block 9 for clamping the workpiece body 14 are provided above the mounting plate 6. All surfaces are designed with an inclined structure. The mounting plate 6 and the upper clamping block 9 are pneumatically controlled. A support frame 7 is fixedly installed on the upper surface of the mounting plate 6, and a clamping cylinder 10 is fixedly installed on the upper surface of the support frame 7. The upper clamping block 9 is fixedly connected to the clamping cylinder 10. A movable slider 12 is fixedly installed on the lower surface of the mounting plate 6, and the movable slider 12 is slidably connected to the limiting slide rail 13 fixedly installed on the upper surface of the support plate 5. A pushing cylinder 11 is fixedly installed on the upper surface of the support plate 5, and the pushing cylinder 11 pushes the mounting plate 6 to slide relative to the limiting slide rail 13.

[0018] When using the device, first place the workpiece body 14 above the lower clamping block 8 above the mounting plate 6, then turn on the clamping cylinder 10. The clamping cylinder 10 pushes the upper clamping block 9 downward, so that the upper clamping block 9 and the lower clamping block 8 cooperate to clamp and fix the workpiece body 14. The inclined surface structure of the upper clamping block 9 and the lower clamping block 8 automatically positions the cylindrical workpiece body 14 and keeps the workpiece body 14 in the center. Then turn on the pushing cylinder 11, and use the pushing cylinder 11 to push the mounting plate 6 to move and feed the workpiece body 14 forward. During the movement of the mounting plate 6, the sliding slider 12 on its lower surface slides on the limiting slide rail 13 to achieve the purpose of limiting the mounting plate 6. Finally, feed the workpiece body 14 to the position of the drilling bit 4 to realize the drilling operation.

[0019] Example 2: Please refer to Figures 4-6 In order to improve the cleaning of drilling debris, this embodiment provides the following technical solution, which specifically discloses: a protective cover 15 for preventing debris from splashing is fixedly installed on the side of the power box 3, and a cleaning mechanism is provided inside the protective cover 15. The cleaning mechanism includes a cleaning nozzle 18 fixedly installed on the inner wall of the protective cover 15 and a blower air pump 20 fixedly installed on the upper surface of the support base 1. The blower air pump 20 is connected to the cleaning nozzle 18 through a delivery pipe 19. A dust collection trough 16 is opened inside the support base 1, and the position of the dust collection trough 16 corresponds to the position of the protective cover 15. A dust collection hopper 17 corresponding to the dust collection trough 16 is fixedly installed inside the support base 1.

[0020] During the drilling process, the protective cover 15 is used to prevent debris from flying away. At the same time, the blower pump 20 is turned on, and air is blown into the cleaning nozzle 18 through the delivery pipe 19. Then, the cleaning nozzle 18 sprays out air, and the airflow blows the debris into the dust collection trough 16. The debris then falls into the dust collection hopper 17 through the dust collection trough 16 and finally falls to the ground for easy subsequent cleaning.
