Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a plastic part drilling tool. Background Art

[0002] Drilling device refers to the general term for equipment used to process holes in solid materials. Common drilling devices include electric drills, drilling machines, etc. The corresponding drilling device is selected according to the actual work needs. Due to the size and weight limitations of drilling machines, they are not suitable for drilling small objects. Therefore, for some small plastic workpieces, drilling operations are mainly performed by manual handheld electric drills. While the electric drill is drilling, it is also necessary to have support objects such as pads and pads to reduce damage to the drill bit. Therefore, when the electric drill is operating, it is necessary to add a variety of decentralized auxiliary devices to operate. This operation method is not conducive to improving the simplicity of the electric drill operation, resulting in poor operability of the device.

[0003] The patent, with the publication number "CN217915688U," is titled: A Lightweight Plastic Drilling Tool. The device described in this public document solves the aforementioned problems, but requires a worker to hold the plastic workpiece and place it between the drill bit and the pressure plate to perform subsequent drilling. This requires manual hand-holding to position the plastic part. When the drill bit drills a hole in the plastic part, the force of the drill bit's rotation drives the plastic part's rotation. The worker needs to increase the force of their hand to ensure stability while drilling. This labor-intensive and time-consuming operation not only increases the worker's workload and intensity, but also affects the accuracy of drilling holes in the plastic part. Based on this, the present invention designs a plastic drilling tool to address the aforementioned problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] The preferred embodiment of the plastic part drilling tool provided by the present utility model is as follows: Figures 1 to 5 As shown: A plastic part drilling tool, including a base 1; a bracket 2 fixedly connected to the top of the base 1; a rotating rod 3 rotatably set at the middle end of the top of the bracket 2; a clamping assembly 4 set on the outer wall of the rotating rod 3, and the clamping assembly 4 can fix the position of the plastic part at the lower end of the bracket 2; the clamping assembly 4 includes a connecting plate 401 threadedly sleeved on the outside of the rotating rod 3, and the bottom surface of the connecting plate 401 is parallel to the top surface of the bracket 2; guide rods 402 fixedly connected to the left and right sides of the bottom of the connecting plate 401, the guide rods 402 slide through the bracket 2, and the two guide rods 402 are parallel to each other; a splint 403 fixedly set at the bottom of the guide rod 402, and the spacing between the two splints 403 is three centimeters.

[0029] It should be noted that the existing plastic part drilling tooling still has certain shortcomings in actual use. Positioning the plastic parts by manual hand-holding can easily cause poor stability when drilling the plastic parts, increase the difficulty and intensity of the workers' work, and affect the drilling accuracy of the plastic parts.

[0030] In this embodiment, the staff first places the plastic part between the bracket 2 and the splint 403, and places the area of ​​the plastic part where drilling is required between the splints 403. The staff then rotates the rotating rod 3 forward, and through the threaded transmission between the rotating rod 3 and the connecting plate 401, the connecting plate 401 drives the guide rod 402 together with the splint 403 to move along the direction of the plastic part, thereby causing the splint 403 to clamp and fix the plastic part.

[0031] In a further preferred embodiment of the present invention, a monitoring component 5 is assembled on the outer wall of the splint 403, and the monitoring component 5 can monitor the clamping force of the splint 403 on the plastic part; the monitoring component 5 includes a thin film pressure sensor 501 fixedly mounted on the bottom of the left splint 403; and a controller 502 fixedly connected to the outer wall of the bracket 2, and the controller 502 is connected to the thin film pressure sensor 501 through a wire.

[0032] In this embodiment, when the splint 403 applies clamping force to the plastic part, the film pressure sensor 501 monitors the clamping force and transmits the monitored force value to the controller 502. The staff can release the rotating rod 3 until the force value displayed on the controller 502 meets the staff's requirements.

[0033] Example 2

[0034] On the basis of Example 1, the preferred embodiment of the plastic part drilling tool provided by the present invention is as follows: Figures 1 to 5As shown: a rotating shaft 6 is connected to the middle side of the top of the bracket 2. The rotating shaft 6 and the guide rod 402 are parallel to each other, and the axis of the rotating shaft 6 is staggered with the axis of the rotating rod 3. Guide holes 7 are integrally provided on the left and right sides of the rear end of the bracket 2. The guide holes 7 are blind holes. A slide 8 is slidably connected inside the guide holes 7. A mounting bracket 9 is fixed to the front end of the slide 8. The cross section of the mounting bracket 9 is rectangular when viewed from the front. The top thread of the mounting bracket 9 is sleeved on the outside of the rotating shaft 6. A driving component is provided inside the bracket 2. The driving component can control the rotating shaft 6 to link the mounting bracket 9 along the longitudinal direction of the bracket 2. The position moves, and the driving assembly includes a mounting plate 10 fixedly mounted on the left and right sides of the upper end of the bracket 2, and a worm 11 is connected inside the mounting plate 10; a worm wheel 12 with gear teeth is arranged on the outer wall of the worm 11, and the worm wheel 12 is fixedly sleeved on the outside of the rotating shaft 6; a handle 13 is fixedly mounted on the right side of the outside of the worm 11, and a motor 14 is fixedly mounted at the bottom of the mounting frame 9, and the motor 14 is connected to the controller 502 through a wire, and the center of the output end of the motor 14 coincides with the center between the two splints 403, and the external threaded sleeve of the output end of the motor 14 is provided with a detachable drill bit 15.

[0035] In this embodiment, after the plastic part is clamped, the staff turns on the motor 14, and the motor 14 drives the drill bit 15 to rotate. The staff then turns the handle 13 forward, and the handle 13 drives the worm 11 to rotate together with the worm wheel 12 and the rotating shaft 6. Through the threaded transmission between the rotating shaft 6 and the mounting frame 9, the mounting frame 9 drives the slide 8 to move downward along the direction of the guide hole 7, that is, the mounting frame 9 drives the motor 14 and the drill bit 15 to move along the direction of the plastic part, so that the drill bit 15 drills the plastic part.

[0036] In a further preferred embodiment of the present invention, a protective component is provided at the bottom of the bracket 2, which can control the motor 14 to stop running, thereby preventing the motor 14 from controlling the rotating drill bit 15 to contact the base 1, and the protective component includes mounting blocks 16 fixed on the left and right sides of the bottom of the bracket 2; an infrared metal sensor 17 fixed on the inner side of the mounting block 16, the two infrared metal sensors 17 are in a one-to-one correspondence design, and the infrared metal sensor 17 is connected to the controller 502 through a wire, a clearance hole 18 is integrally provided on the middle side of the lower end of the bracket 2, the clearance hole 18 is a through hole design, and the clearance hole 18 and the drill bit 15 correspond one-to-one to each other, a avoidance hole 19 is integrally provided inside the guide rod 402, the avoidance hole 19 is a through hole design, and the avoidance hole 19 is sleeved on the outside of the worm 11, and a limit plate 20 is fixedly sleeved on the lower end of the outer side of the rotating shaft 6, the cross-section of the limit plate 20 is a circular design when viewed from above, and the limit plate 20 is coaxial with the rotating shaft 6.

[0037] In this embodiment, after the drill bit 15 penetrates the plastic part, the drill bit 15 moves from the avoidance hole 18 to the position between the infrared metal sensors 17, that is, the drill bit 15 blocks the path of mutual monitoring of the infrared metal sensors 17, and the motor 14 stops running to prevent the staff from continuing to rotate the handle 13 forward due to misoperation, causing the rotating drill bit 15 to contact the base 1, thereby protecting the drill bit 15 and the base 1. The avoidance hole 19 makes room for the displacement of the guide rod 402, and the limit plate 20 can prevent the rotating shaft 6 from separating from the mounting bracket 9.

[0038] To sum up, this application can not only clamp and fix plastic parts through the design of mechanical linkage, but also control the clamping force of the plastic parts within the range required by the staff. In addition, through the design of protective function, it can prevent the rotating drill bit from contacting the base, thereby protecting the drill bit.
