Description

Technical Field

[0001] This utility model relates to the field of woodworking drilling tools, specifically a woodworking positioning drill. Background Technology

[0002] Traditional woodworking drilling methods, such as using hand chisels or simple drilling tools, have many drawbacks. Hand chiseling relies on the craftsman's experience and skills, is inefficient, and makes it difficult to guarantee the consistency and accuracy of the hole position. Moreover, most woodworking positioning drills do not have the ability to easily change the mold holes of different sizes or adjust the arc angle when drilling. In woodworking, different projects often require the use of drilling molds of different sizes and shapes. In actual woodworking work, in addition to conventional vertical drilling, there are often situations where it is necessary to adjust the arc angle when drilling, such as making stair railings and curved furniture frames.

[0003] For example, the prior art application number CN221985322U provides a woodworking positioning drill, which includes a fixed plate. A U-shaped guide rod is fixedly installed on one side of the fixed plate, and a movable block is slidably connected to the U-shaped guide rod. This woodworking positioning drill, through the coordinated arrangement of a damping shaft, a positioning guide plate, a drilling mounting base, a threaded hole, a limiting drilling cylinder, a second fastening knob, a hand-tightening screw, a stop block, and a rubber pad, allows the drill to be installed on the board. Tightening the hand-tightening screw moves the stop block to fix the drill. Then, the positioning guide plate and the movable block are adjusted to form an angle by the damping shaft. The drilling mounting base is then moved to a suitable position, and the second fastening knob is tightened for fixation. A suitable limiting drilling cylinder is then screwed into the threaded hole, thus facilitating drilling on the folded surface of the wood board and effectively preventing hole deviation.

[0004] Based on actual usage, the aforementioned prior art mainly achieves convenient drilling and avoids hole deviation through positioning guide plates and drilling mounting bases; however, it has been found that it cannot easily replace mold holes of different specifications or adjust the arc angle during drilling, which fails to meet the diverse needs of woodworking when arc angle drilling is required or when changing mold holes. Therefore, based on actual usage, we have improved the aforementioned prior art. Utility Model Content

Square movable slots are provided on the side walls of both sets of pressure plates.

[0012] Furthermore: the arc-shaped rotating block includes an arc-shaped through groove on its outer side wall, and the bottom outer side wall of the arc-shaped rotating block is provided with an angle scale.

[0013] Furthermore: the top of the movable clamping plate is threadedly connected to a matching fifth fixing abutment screw, one end of the bottom of the fifth fixing abutment screw extends to the top outer wall of the base plate, and a bubble level is provided on one side outer wall of the movable clamping plate, and a sixth fixing abutment screw is threadedly connected to the bottom side wall of the movable clamping plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model allows for convenient replacement of mold holes of different specifications and adjustment of arc angles during drilling by rotating the mold assembly. It meets diverse woodworking needs when arc angle drilling and mold hole replacement are required, and is easy to operate. Specifically, during the limiting position, the worker manually slides a movable clamping plate connected to one side of the base plate towards the fixed base plate to adapt to different widths of the wood board for clamping. The first fixed abutment screw and the sixth fixed abutment screw, connected by a groove on the bottom side wall of the movable clamping plate, are manually rotated to abut against the outer wall of the wood board, completing the fixation on the side wall of the wood board. Furthermore, a bubble level is installed on the outer wall of one side of the movable clamping plate for easy observation of the horizontal angle and adjustment. The entire assembly is completed by manually rotating the fifth fixed abutment screw, which is threaded to the top of the movable clamping plate, to rotate and abut against the outer wall of the top of the base plate. This fixes the movable clamping plate to the base plate. The worker then adjusts the sliding block by sliding it to the outer walls of both sides of the base plate. The first scale is embedded on the outer wall of one side of the base plate to observe the lateral position for drilling at the corresponding location. The worker then manually rotates the second fixed abutment screw to make one end abut against the top side wall of the base plate, thus fixing the movable block to the top side wall of the base plate. The arc-shaped rotating block, including the arc-shaped through groove on its outer wall, drives the movable block to adjust the arc rotation angle on the outer wall of the screw. The screw is threaded to a fixing cap on the outer wall of the top of the arc-shaped rotating block, and the worker manually rotates the fixing cap downwards. The arc-shaped rotating block is attached to the top outer wall to fix the arc angle. The angle is observed and adjusted using the angle scale on the bottom outer wall of the arc-shaped rotating block. The support block is manually slidable on one side of the moving block and the inner wall of the connecting moving block to adjust the vertical position of the conversion perforated plate. The vertical position of the conversion perforated plate is observed using the second scale on the top of one side of the connecting moving block. A matching third fixing screw is threaded onto the other side of the support block's outer wall for manual rotation, securing the support block to the connecting moving block's outer wall. When changing the mold, the conversion perforated plate, which includes a corresponding circular perforation slot on one side, a corresponding triangular slot on the bottom side, and a corresponding square perforation slot, requires... During replacement, an abutment plate is installed on the outer wall of the perforated plate adjacent to the fourth fixing screw, which aligns with the bottom of the square fixing groove. The fourth fixing screw is manually rotated so that one end abuts against the top outer wall of the abutment plate, thus fixing the corresponding circular perforated groove. When replacing the corresponding triangular groove and the corresponding square perforated groove, two sets of identical pressure plates are symmetrically arranged on both sides of the abutment plate. Each pressure plate has a square movable groove on its side wall, which facilitates manual rotation of the fourth fixing screw so that one end passes through and abuts against the bottom outer wall of the pressure plate. Since the fixing components of the corresponding triangular groove and the corresponding square perforated groove have the same structure, the operation is the same, thus completing the fixing of the corresponding triangular groove and the corresponding square perforated groove.The aforementioned operations allow for convenient replacement of mold holes of different specifications and adjustment of the arc angle during drilling. This meets diverse woodworking needs when requiring arc-angle drilling and mold hole changes, offering ease of operation.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a woodworking positioning and drilling tool, including a base plate 1, a first scale code 2 embedded on one outer wall of the base plate 1, a rotating mold assembly 6 slidably connected to both outer walls of the base plate 1, a movable clamping plate 3 slidably connected to one outer wall of the base plate 1, and a fixed base plate 4 provided on the other outer wall of the base plate 1.

It meets the diverse needs of woodworking when woodworking requires arc angle drilling and when changing mold holes, and is easy to operate.

[0028] Preferably, the rotating mold assembly 6 includes a movable block 61 slidably connected to the base plate 1. A second fixed abutment screw 62 is threadedly connected to the bottom side wall of the movable block 61. One end of the second fixed abutment screw 62 extends to the top side wall of the base plate 1. A screw 65 is provided on the top side wall of one end of the movable block 61. An arc-shaped rotating block 63 is provided on the outside of the screw 65. A fixing cap 64 is threadedly connected to the top outer side wall of the arc-shaped rotating block 63 adjacent to the screw 65. A connecting movable block 66 is provided on one side outer wall of the arc-shaped rotating block 63. The worker then slides and adjusts the movable block 61 on both sides of the base plate 1. A first scale 2 is embedded on one side outer wall of the base plate 1 to observe the lateral position where drilling is required. The worker then manually rotates the mold assembly 61 using the second fixed abutment screw 62. One end of the bottom abuts against the top side wall of the base plate 1, thus fixing the moving block 61 to the top side wall of the base plate 1. The arc-shaped rotating block 63, including the arc-shaped through groove 631 opened on the outer side wall, drives the connecting moving block 66 to adjust the arc-shaped rotation angle on the outer wall of the screw 65. The screw 65 is threadedly connected to the top outer side wall of the arc-shaped rotating block 63. The fixing cap 64 is manually rotated so that the fixing cap 64 abuts against the top outer side wall of the arc-shaped rotating block 63, thus fixing the arc angle. The support block 661 is then manually supported and slid on one side of the moving block 66 and the inner side wall of the connecting moving block 66 to adjust the vertical position of the conversion punch plate 666. The vertical position of the conversion punch plate 666 is observed through the second scale 662 set on the top of one side of the connecting moving block 66.

[0029] Preferably, a support block 661 is slidably connected to one side of the connecting movable block 66. The outer wall of one side of the support block 661 is slidably connected to the inner wall of the connecting movable block 66. A second scale mark 662 is provided on the top of one side of the connecting movable block 66. A matching third fixing abutment screw 663 is threadedly connected to the outer wall of the other side of the support block 661. One end of the third fixing abutment screw 663 extends to the outer wall of one side of the connecting movable block 66. A matching fourth fixing abutment screw 664 is threadedly connected to the outer wall of the top of the support block 661. A square fixing groove 665 is opened on the outer wall of one end of the support block 661. The bottom of the fourth fixing abutment screw 664 is... One end extends into the inner cavity of the square fixing groove 665, and the inner cavity of the square fixing groove 665 is provided with a mold conversion perforation plate 666. It is then manually supported and slidable on one side of the moving block 66 and the inner wall of the connecting moving block 66 by the support block 661, so as to adjust the vertical position of the conversion perforation plate 666. The vertical position of the conversion perforation plate 666 can be observed by the second scale 662 set on the top of one side of the connecting moving block 66. The third fixing abutment screw 663, which is threaded to the outer wall of the other side of the support block 661, is manually rotated to abut against the outer wall of one side of the connecting moving block 66, thus completing the fixation of the support block 661 on the connecting moving block 66.

[0030] Preferably, the mold conversion perforation plate 666 includes a corresponding circular perforation slot 6666 on one side, a corresponding square perforation slot 6662 on the top side of the conversion perforation plate 666, and a corresponding triangular slot 6663 on the bottom side of the conversion perforation plate 666. An abutment plate 6661 is provided on the outer wall of the conversion perforation plate 666 adjacent to the fourth fixed abutment screw 664. Two sets of identical pressing plates 6664 are symmetrically arranged on both sides of the abutment plate 6661. Both sets of pressing plates 6664 have square movable slots 6665 on their side walls. When changing molds, if the corresponding circular perforation slot 6666 on one side, the corresponding triangular slot 6663 on the bottom side, and the corresponding square perforation slot 6662 need to be replaced, the abutment plate 6666 on the outer wall of the conversion perforation plate 666 adjacent to the fourth fixed abutment screw 664 is provided. 61 is connected to the bottom of the inner cavity of the square fixing groove 665. The bottom end is manually rotated by the fourth fixing abutment screw 664 so that it abuts against the top outer wall of the abutment plate 6661, thus completing the fixing of the corresponding circular punched groove 6666. When the corresponding triangular groove 6663 and the corresponding square punched groove 6662 are interchanged, two sets of pressure plates 6664 with the same structure are symmetrically arranged on both sides of the abutment plate 6661. They are connected to the bottom of the inner cavity of the square fixing groove 665 by square movable grooves 6665. The side walls of the pressure plates 6664 are all provided with square movable grooves 6665 to facilitate the manual rotation of the fourth fixing abutment screw 664 so that the bottom end passes through and abuts against the bottom outer wall of the pressure plate 6664. Since the fixing components of the corresponding triangular groove 6663 and the corresponding square punched groove 6662 have the same structure and the same operation, the fixing of the corresponding triangular groove 6663 and the corresponding square punched groove 6662 is completed.

[0031] Preferably, the arc-shaped rotating block 63 includes an arc-shaped through groove 631 on its outer side wall, and an angle scale 632 is provided on the bottom outer side wall of the arc-shaped rotating block 63. The arc-shaped rotating block 63, including the arc-shaped through groove 631 on its outer side wall, drives the connecting moving block 66 to adjust the arc-shaped rotation angle on the outer wall of the screw 65. The screw 65 is threadedly connected to the top outer side wall of the arc-shaped rotating block 63, and the fixing cap 64 is manually rotated so that the fixing cap 64 abuts against the top outer side wall of the arc-shaped rotating block 63, thus fixing the arc angle. The angle is observed and adjusted by the angle scale 632 provided on the bottom outer side wall of the arc-shaped rotating block 63.

[0032] Preferably, the top of the movable clamping plate 3 is threaded with a matching fifth fixing abutment screw 32, one end of the bottom of the fifth fixing abutment screw 32 extends to the top outer wall of the base plate 1, and a bubble level 33 is provided on one side outer wall of the movable clamping plate 3, and a sixth fixing abutment screw 31 is threadedly connected to the bottom side wall of the movable clamping plate 3. The first fixing abutment screw 5 and the sixth fixing abutment screw 31 threadedly connected to the bottom side wall of the movable clamping plate 3 are manually rotated and abut against the outer wall of the wooden board to complete the fixation on the side wall of the wooden board. The bubble level 33 provided on one side outer wall of the movable clamping plate 3 facilitates observation of the horizontal angle and makes adjustments.

[0033] Example: At the start of work, when the wooden board is in position, the worker manually slides the movable clamping plate 3, which is slidably connected to the outer wall of one end of the base plate 1, toward the fixed base plate 4 to accommodate different widths of the wooden board and clamp it in place. The first fixed abutment screw 5 and the sixth fixed abutment screw 31, which is threaded to the bottom side wall of the movable clamping plate 3, are manually rotated to abut against the outer wall of the wooden board, thus fixing it to the side wall. A bubble level 33 is installed on one side of the outer wall of the movable clamping plate 3 to facilitate observation of the horizontal angle and make adjustments. Then, by manually rotating the fifth fixed abutment screw 32, which is threaded to the top of the movable clamping plate 3, it rotates to abut against the top outer wall of the base plate 1, completing the fixation of the movable clamping plate 3 on the base plate 1. The worker then slides the movable block 61, which is slidably connected to the outer walls of both sides of the base plate 1. The adjustment involves observing the lateral position of the hole to be drilled by the first scale code 2 embedded on the outer wall of one side of the base plate 1. Then, the bottom end of the second fixing screw 62 is manually rotated to abut against the top side wall of the base plate 1, thus fixing the moving block 61 to the top side wall of the base plate 1. The arc-shaped rotating block 63, including the arc-shaped through groove 631 on the outer wall, drives the connecting moving block 66 to adjust the arc-shaped rotation angle on the outer wall of the screw 65. The screw 65 is threaded to the top outer wall of the arc-shaped rotating block 63, and the fixing cap 64 is manually rotated to abut against the top outer wall of the arc-shaped rotating block 63, thus fixing the arc angle. The angle is observed and adjusted by the angle degree scale code 632 set on the bottom outer wall of the arc-shaped rotating block 63.

[0034] Furthermore, the vertical position of the conversion perforated plate 666 is adjusted by manually sliding the support block 661 on one side of the movable block 66 and the inner wall of the connecting movable block 66. The vertical position of the conversion perforated plate 666 is observed by the second scale 662 set on the top of one side of the connecting movable block 66. The third fixed abutment screw 663, which is threaded to the outer wall of the other side of the support block 661, is manually rotated to abut against the outer wall of one side of the connecting movable block 66, thus fixing the support block 661 on the connecting movable block 66. When changing the mold, the conversion perforated plate 666, which includes a corresponding circular perforation slot 6666 on one side, a corresponding triangular slot 6663 on the bottom side, and a corresponding square perforation slot 6662, needs to be changed. The abutment plate 6661, which is set on the outer wall of the conversion perforated plate 666 adjacent to the fourth fixed abutment screw 664, is connected to the bottom of the inner cavity of the square fixed slot 665. The bottom is manually rotated by the fourth fixed abutment screw 664. The end abuts against the top outer wall of the abutment plate 6661, completing the fixation of the corresponding circular punched slot 6666. When the corresponding triangular slot 6663 and the corresponding square punched slot 6662 are interchanged, two sets of identical pressure plates 6664 symmetrically arranged on both sides of the abutment plate 6661 are connected to the bottom of the inner cavity of the square fixed slot 665 through square movable slots 6665. The side walls of the pressure plates 6664 are all provided with square movable slots 6665 to facilitate manual operation of the fourth fixed abutment screw 664. Rotating the plate causes one end to pass through and abut against the outer side wall of the bottom of the clamping plate 6664. Since the corresponding triangular groove 6663 and the corresponding square punching groove 6662 have the same fixing structure and the same operation, the corresponding triangular groove 6663 and the corresponding square punching groove 6662 are fixed. The above operation can easily replace mold holes of different specifications and adjust the arc angle for drilling. It meets the diverse needs of woodworkers when they need to drill holes at arc angles and change mold holes, and the operation is convenient.

[0035] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
