Description

Technical Field

[0001] This application relates to the field of drilling technology, and in particular to a user-friendly drilling apparatus. Background Technology

[0002] Currently, drilling workpieces using drilling equipment is a very common and important operation in industrial production, and it is widely used in many industries such as machinery manufacturing and electronic equipment processing.

[0003] Currently, the conventional drilling process is as follows: first, the workpiece is securely fixed using a support to ensure that its position remains unchanged during the drilling process; then, the drill bit is moved to accurately contact the workpiece surface; finally, the drill bit is driven to rotate using a motor or hand crank to achieve the goal of drilling a hole in the workpiece.

[0004] However, manual operation requires workers to exert considerable force continuously, resulting in high labor intensity and easy operator fatigue. This not only leads to low drilling efficiency but also makes it difficult to guarantee the stability of drilling quality, severely restricting the improvement of production progress and product quality. There are areas for improvement. Utility Model Content

[0005] To improve the efficiency of drilling operations, this application provides an easy-to-use drilling device.

[0006] This application provides a user-friendly drilling device, which adopts the following technical solution:

[0007] A user-friendly drilling device includes a base and a connecting seat. The connecting seat is fixedly mounted on the base. A drill bit and a drill bit fixing mechanism for fixing the drill bit are slidably mounted on the base. The connecting seat is provided with a three-jaw chuck for clamping a workpiece and a first motor for driving the three-jaw chuck to rotate. The output shaft of the first motor is coaxially fixed with the three-jaw chuck.

[0008] By adopting the above technical solution, the three-jaw chuck can clamp and fix workpieces of different specifications and shapes. At the same time, the drill bit fixing mechanism forms a sliding fit with the machine base. The operator slides the drill bit on the drill bit fixing mechanism until it is pressed against the workpiece. When the first motor drives the three-jaw chuck to rotate, the drill bit on the drill bit fixing mechanism can perform stable fixed-point drilling on the workpiece, which improves the flexibility and efficiency of drilling.

[0009] Preferably, the drill bit fixing mechanism includes a sliding plate, a fixing seat, and a top cover. The sliding plate is slidably mounted on the machine base, the fixing seat is mounted on the sliding plate, and the fixing seat is provided with a feeding block for fixing and placing the drill bit. The drill bit is positioned between the top cover and the feeding block, and the top cover and the feeding block are connected by bolts.

[0010] By adopting the above technical solution, the sliding plate is slidably mounted on the machine base, making it convenient to adjust the drill bit to slide and contact the workpiece; at the same time, the drill bit is fixedly mounted between the upper cover and the feeding block, and the feeding block and the upper cover are connected by bolts. This structure facilitates the installation and disassembly of the drill bit and improves the convenience of drill bit replacement.

[0011] Preferably, the material feeding block is provided with a lower half-groove and a snap-fit ​​block. The snap-fit ​​block is disposed in the lower half-groove. The upper cover is provided with an upper half-groove for fitting with the drill bit. The drill bit and the lower half-groove form an embedded fit. An installation space for fixing the drill bit is formed between the upper half-groove and the lower half-groove. The drill bit is provided with a snap-fit ​​groove for snap-fitting with the snap-fit ​​block.

[0012] By adopting the above technical solution, the upper half of the cover and the lower half of the material feeding block form an installation space for fixing the drill bit, and the snap-fit ​​block and the snap-fit ​​groove on the drill bit form a snap-fit ​​fit, thereby enabling more precise positioning and fixing of the drill bit, preventing the drill bit from shifting or shaking during the drilling process, and ensuring the accuracy of drilling.

[0013] Preferably, the sliding plate is provided with a sliding groove, and the bottom of the fixed seat is provided with a second slider for sliding cooperation with the sliding groove and a locking bolt for locking the fixed seat. The locking bolt passes through the fixed seat and forms an abutment cooperation with the bottom of the sliding groove.

[0014] By adopting the above technical solution, the second slider at the bottom of the fixed seat forms a sliding engagement with the sliding groove on the sliding plate, allowing the fixed seat to move flexibly on the sliding plate and facilitating the adjustment of the drill bit position; at the same time, the locking bolt is used to lock the fixed seat in the required position, ensuring that the fixed seat will not be displaced during the drilling process, thus guaranteeing the stability and accuracy of the drilling.

[0015] Preferably, a support seat for fixing the position of the drill bit fixing mechanism is slidably provided on the base, and the support seat and the drill bit fixing mechanism form a tight fit.

[0016] By adopting the above technical solution, after the drill bit fixing mechanism slides to abut against the workpiece, the worker slides the support seat to abut against the drill bit fixing mechanism, which further enhances the stability of the drill bit fixing mechanism, prevents the drill bit from moving backward due to external force during drilling, and further improves the stability during drilling.

[0017] Preferably, the support base includes a base body, a lead screw, and a handwheel. The base body is slidably mounted on the machine base, the lead screw is rotatably connected to the machine base, and the lead screw is threadedly connected to the base body. The handwheel is coaxially fixed with the lead screw, and the base body forms an abutting fit with the drill bit fixing mechanism.

[0018] By adopting the above technical solution, the operator can drive the lead screw to rotate by turning the handwheel, thereby causing the base to slide on the machine base. This allows the operator to accurately adjust the position of the support base as needed, thus better supporting and positioning the drill bit fixing mechanism. At the same time, the drilling position of the drill bit can be finely adjusted by turning the handwheel.

[0019] Preferably, a collection tray for collecting fallen debris is provided on one side of the base.

[0020] By adopting the above technical solution and using the collection tray, the collection tray can collect the debris that falls during drilling, keep the working environment clean, reduce the pollution of the working area by the debris, and facilitate the centralized treatment of the debris.

[0021] Preferably, the bottom of the base is provided with a collection groove for collecting debris, and the collection groove is inclined toward the collection tray.

[0022] By adopting the above technical solution, the collection groove at the bottom of the machine base is inclined toward the collection tray, which facilitates the automatic sliding of debris into the collection tray, improves the efficiency of debris collection, avoids the accumulation of debris at the bottom of the machine base, and further optimizes the working environment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By using the three-jaw chuck, the three-jaw chuck can clamp and fix workpieces of different specifications and shapes. At the same time, the drill bit fixing mechanism forms a sliding fit with the machine base. The operator slides the drill bit on the drill bit fixing mechanism until it is pressed against the workpiece. When the first motor drives the three-jaw chuck to rotate, the drill bit on the drill bit fixing mechanism can perform stable fixed-point drilling on the workpiece, which improves the flexibility and efficiency of drilling.

[0025] 2. The upper half of the cover and the lower half of the material feeding block form a space for fixing the drill bit, and the snap-fit ​​block and the snap-fit ​​groove on the drill bit form a snap-fit ​​fit, which can more accurately position and fix the drill bit, prevent the drill bit from shifting or shaking during the drilling process, and ensure the drilling accuracy.

[0026] 3. The operator drives the lead screw to rotate by turning the handwheel, which causes the base to slide on the machine base. This allows the operator to precisely adjust the position of the support base as needed, thereby better supporting and positioning the drill bit fixing mechanism. At the same time, the drilling position of the drill bit can be finely adjusted by turning the handwheel. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0032] This application discloses a drilling device that is easy to use.

[0033] Reference Figure 1 A user-friendly drilling device includes a base 1 and a connecting seat 2. The connecting seat 2 is fixedly mounted on the base 1 by bolts. The base 1 is provided with a drill bit 3 and a drill bit fixing mechanism 4 for fixing the drill bit 3. The connecting seat 2 is provided with a three-jaw chuck 21 and a first motor 22. The output shaft of the first motor 22 is coaxially fixed with the three-jaw chuck 21. The three-jaw chuck 21 is used to clamp workpieces of different specifications. When in use, the central axis of the drill bit 3 and the rotation axis of the three-jaw chuck 21 are on the same horizontal line.

[0034] Reference Figure 1 and Figure 2 The drill bit fixing mechanism 4 includes a sliding plate 41, a fixing seat 42, and an upper cover 43. A feeding block 44 is welded onto the fixing seat 42. The feeding block 44 is provided with a lower half groove 441 and a snap-fit ​​block 442. The lower half groove 441 is semi-circular and adapted to the diameter of the drill bit 3. The snap-fit ​​block 442 is integrally formed in the lower half groove 441 of the feeding block 44. The upper cover 43 is threadedly connected to the feeding block 44 by bolts. The upper cover 43 is provided with an upper half groove 431 that is symmetrical to the lower half groove 441. That is, the upper half groove 431 and the lower half groove 441 form an installation space for fixing the drill bit 3. The drill bit 3 is embedded in the lower half groove 441, and the drill bit 3 is provided with a snap-fit ​​groove for snap-fitting with the snap-fit ​​block 442.

[0035] Reference Figure 2When installing drill bit 3, insert drill bit 3 into the lower half groove 441 and make the snap-fit ​​block 442 snap into the snap-fit ​​groove on drill bit 3. After closing the upper cover 43, the upper cover 43 and the material feeding block 44 are fastened by bolts, thereby achieving accurate fixing of drill bit 3, preventing drill bit 3 from shifting or shaking during drilling, and ensuring drilling accuracy.

[0036] Reference Figure 1 and Figure 2 The base 1 is symmetrically equipped with guide rails 11. The bottom of the sliding plate 41 is formed with a first slider 411 for sliding cooperation with the guide rail 11. The sliding plate 41 is provided with a sliding groove 412 along its length direction. The bottom of the fixed seat 42 is formed with a second slider 421 for sliding cooperation with the sliding groove 412. The sliding direction of the first slider 411 is parallel to the width direction of the sliding plate 41. The fixed seat 42 is also provided with a locking bolt 422. The locking bolt 422 passes through the fixed seat 42 and forms an abutment cooperation with the bottom of the sliding groove 412.

[0037] Reference Figure 1 and Figure 2 In use, the operator loosens the locking bolt 422 to allow the fixed seat 42 to slide along the length of the sliding groove 412. After adjustment, the locking bolt 422 is tightened to fix the fixed seat 42 on the sliding plate 41. Then, the drill bit 3 on the fixed seat 42 is slid to abut against the workpiece on the three-jaw chuck 21. When the first motor 22 drives the three-jaw chuck 21 to rotate, the drill bit 3 on the drill bit fixing mechanism 4 can perform stable fixed-point drilling on the workpiece, improving the flexibility and efficiency of drilling.

[0038] Reference Figure 1 The machine base 1 is also provided with a support base 5, which is used to fix the position of the fixed base 42 during the drilling process. The support base 5 includes a base body 51, a lead screw 52 and a handwheel 53. The bottom of the base body 51 is slidably mounted on the machine base 1 via a slide rail. The length direction of the lead screw 52 is parallel to the length direction of the guide rail 11, and the lead screw 52 is rotatably connected to the machine base 1. The bottom of the base body 51 is provided with a threaded hole for forming a threaded connection with the lead screw 52. The handwheel 53 is coaxially fixed with the lead screw 52.

[0039] Reference Figure 1 When in use, the operator turns the handwheel 53 to drive the lead screw 52 to rotate, so that the seat 51 slides on the guide rail 11 and abuts against the fixed seat 42, which further enhances the stability of the drill bit 3 during the drilling process and prevents the drill bit 3 from moving backward due to external force during the drilling process, thus further improving the stability of the drilling process.

[0040] Reference Figure 1The base 1 has a collection trough 12 for collecting debris at its bottom. The collection trough 12 is located below the guide rail 11. A plug-in slot 13 is provided on one side of the base 1. A collection tray 14 is inserted into the plug-in slot 13 of the base 1. The collection tray 14 is placed on the ground. The collection trough 12 is tilted toward the collection tray 14. Thus, the debris generated during drilling will first fall into the collection trough 12 on the base 1, and then tilt and slide into the collection tray 14 under the action of gravity. This improves the efficiency of debris collection and makes it convenient for staff to regularly collect and process the debris in the collection tray 14.

[0041] The implementation principle of this application embodiment is as follows: In actual operation, the operator first clamps the workpiece with the three-jaw chuck 21, then rotates the three-jaw chuck 21 to adjust the workpiece to the required angle, then loosens the locking bolt 422, slides the fixed seat 42 and makes the central axis of the drill bit 3 horizontally aligned with the rotation axis of the three-jaw chuck 21. After adjusting the position of the fixed seat 42, tighten the locking bolt 422, then push the sliding plate 41 to slide and make the drill bit 3 abut against the workpiece, then rotate the handwheel 53 to drive the support seat 5 to abut against the fixed seat 42, and finally start the first motor 22 to drive the three-jaw chuck 21 to rotate the workpiece. At the same time, the position of the drill bit 3 on the support seat 5 and the fixed seat 42 is finely adjusted by rotating the handwheel 53 so that the drill bit 3 cuts into the workpiece to complete the drilling operation.

[0042] Example 2:

[0043] The difference between Example 2 and Example 1 is that:

[0044] Reference Figure 3 The drill bit 3 is rotatably connected between the upper half groove 431 of the upper cover 43 and the lower half groove 441 of the feeding block 44. The top of the support base 5 is equipped with a second motor 54. The output shaft of the second motor 54 is coaxially connected to the end of the drill bit 3 away from the workpiece through a coupling, so that the second motor 54 can drive the drill bit 3 to rotate stably between the upper cover 43 and the feeding block 44.

[0045] The implementation principle of this application embodiment is as follows: when it is necessary to process an annular hole in the workpiece, the output shaft of the second motor 54 is connected to the drill bit 3 through a coupling. The second motor 54 drives the drill bit 3 to process the workpiece. Since the first motor 22 drives the three-jaw chuck 21 to rotate the workpiece, the drill bit 3 can perform drilling operations at different angles on the workpiece.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
