[0022] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-10 This invention proposes a grooving and drilling integrated machine for measuring ruler handles, including a support plate 1, a turntable 2 rotatably connected to the upper side of the support plate 1, a fixed seat 3 and a pneumatic clamp 4 fixedly installed on the upper side of the turntable 2, and the measuring ruler handle placed on the fixed seat 3 can be fixed by using the pneumatic clamp 4. The support plate 1 is provided with a drilling mechanism 5, a chamfering component 6, a grooving component 7 and a dust collection mechanism 8.

[0025] In an embodiment of the present invention, in order to drill a hole in the handle of the measuring ruler and grind the inner wall of the hole, specifically, the drilling mechanism 5 includes an adjusting component 51 and a mounting plate 54. The adjusting component 51 is mounted on the support plate 1 and has a movable frame 52. A mounting component 53 is fixedly connected to the outer wall of the movable frame 52. The mounting plate 54 is connected to the output end of an electric telescopic rod 55, which is fixedly mounted on the mounting component 53. A drilling machine is fixedly mounted on the mounting plate 54, and a drill bit 56 is detachably connected to the output end of the drilling machine. A V-shaped annular groove 561 is formed on the outer wall of the drill bit 56, and an arc-shaped rod 562 is welded into the V-shaped annular groove 561. The arc-shaped rod 562 passes through the grinding disc 563 and slides with the grinding disc 563. During the drilling process, as the drill bit 56 rotates, the grinding disc 563 slides horizontally relative to the arc-shaped rod 562 under centrifugal force. The adjusting component 51 adjusts the position of the moving frame 52 so that the drill bit 56 is aligned with the position to be drilled on the handle. The drilling machine drives the drill bit 56 to rotate at high speed to drill the workpiece. During the drilling process, the rotation of the drill bit 56 generates centrifugal force, which drives the grinding disc 563 to slide horizontally along the arc-shaped rod 562 to the outside of the V-shaped groove 561, contacting and grinding the inner wall of the hole. After drilling is completed, the electric telescopic rod 55 retracts, the drill bit 56 stops rotating, and the grinding disc 563 returns to its original position under gravity, effectively removing burrs and cutting residues from the hole, ensuring the smoothness of the inner wall of the drilled hole, improving the fitting accuracy of the measuring ruler handle and the connecting parts, and reducing the risk of assembly wear.

[0026] Furthermore, to prevent the drill bit 56 from contacting the fixed seat 3 and to protect the fixed seat 3, specifically, the adjusting assembly 51 includes a fixed frame 511, in which a screw 512 is rotatably connected. A motor 513 is fixedly connected to the fixed frame 511, and the output shaft of the motor 513 is fixedly connected to the screw 512. A guide rod 514 is fixedly connected to the fixed frame 511, and the guide rod 514 passes through the movable protective assembly 515. The movable protective assembly 515 includes a movable block 5151, which is rotatably connected to a threaded sleeve 5152. A notch 5153 is provided on the threaded sleeve 5152. A clamping block 5155 is slidably connected to the movable block 5151, and the clamping block 5155 is fixed to an elastic telescopic rod 5154. The sleeve portion of the elastic telescopic rod 5154 is fixedly connected to the movable block 5151, and the movable block 5151 is slidably connected to the guide rod 514. The threaded sleeve 5152 is threadedly connected to the screw 512. A limit block 57 is fixedly connected to the outer wall of the fixed frame 511. When the moving block 5151 is not in contact with the limit block 57, the screw 512 is driven to rotate by the motor 513. During this process, the threaded sleeve 5152 will not rotate due to friction caused by the clamping block 5155 fixing it. Then, under the action of the guide rod 514, the moving block 5151 moves up and down, thereby adjusting the lifting and lowering of the drill bit 56, which facilitates the drill bit 56 to drill holes in the measuring ruler handle. When the moving block 5151 is in contact with the limit block 57, the threaded sleeve 5152 will rotate when the motor 513 drives the screw 512 to rotate, overcoming the friction of the clamping block 5155 on the threaded sleeve 5152, preventing the moving block 5151 from falling too far, and thus preventing the drill bit 56 from contacting the turntable 2, thereby protecting the turntable 2 and achieving a protective effect.

[0027] In an embodiment of the present invention, in order to chamfer the handle of the measuring ruler, the chamfering assembly 6 specifically includes an adjusting seat 61, which is slidably connected to the guide rail 62. A second motor 63 is fixedly connected to the adjusting seat 61, and a chamfering rod 64 is fixedly connected to the output shaft of the second motor 63. The adjusting seat 61 slides along the guide rail 62 to the corresponding position; the second motor 63 drives the chamfering rod 64 to rotate at high speed, and the turntable 2 rotates the handle to below the chamfering rod 64, so that the chamfering rod 64 contacts the part to be chamfered, thus completing the chamfering process.

[0028] Furthermore, in order to perform grooving on the measuring ruler handle, the grooving assembly 7 specifically includes a U-shaped frame 71, a cutting wheel 72 rotatably connected in the U-shaped frame 71, a motor 73 fixedly connected to the U-shaped frame 71, the motor 73 driving the cutting wheel 72 to rotate, a connecting block 74 fixedly connected to the lower side of the U-shaped frame 71, the connecting block 74 being fixed to the electric telescopic rod 75, the motor 73 driving the cutting wheel 72 to rotate at high speed, the electric telescopic rod 75 extending to push the connecting block 74 and the U-shaped frame 71 to move, so that the cutting wheel 72 contacts the part of the handle to be grooved; the turntable 2 drives the handle to move at a uniform speed, the cutting wheel 72 cuts the workpiece to form the required groove shape; after grooving is completed, the electric telescopic rod 75 retracts, and the cutting wheel 72 moves away from the workpiece.

[0029] In an embodiment of the present invention, in order to absorb and process the drilling debris, the dust collection mechanism 8 specifically includes a blocking component 81, a hose 82, a collection box 83, and a negative pressure fan 84. The hose 82 is connected to the collection box 83, and the negative pressure fan 84 drives the collection box 83 to generate negative pressure, thereby sucking the drilling debris into the collection box 83 through the hose 82. The blocking component 81 includes a first blocking cover 811, which is fixedly connected to the lower side of the mounting plate 54, and a second blocking cover 811 is slidably connected to the first blocking cover 811. 12. The hose 82 is connected to the first baffle 811. During drilling, the first baffle 811 moves down with the mounting plate 54, and the second baffle 812 automatically extends due to gravity or contact with the workpiece, surrounding the processing area of ​​the drill bit 56 and the workpiece. The negative pressure fan 84 is started, which generates negative pressure in the collection box 83. The debris generated during processing is confined in the baffle and sucked into the collection box 83 through the hose 82. After drilling is completed, the first baffle 811 moves up with the mounting plate 54, and the second baffle 812 is reset, reducing debris splashing and preventing dust from affecting processing.

[0030] Furthermore, a wedge block 813 is fixedly connected to the second blocking cover 812. The first blocking cover 811 is penetrated by a crossbar 814 and slidably connected to the crossbar 814. A positioning ring 816 is fixedly connected to the end of the crossbar 814 near the drill bit 56. A rotating roller 817 is rotatably connected to the positioning ring 816. A rotating wheel 815 is fixedly connected to the end of the crossbar 814 away from the drill bit 56. The rotating wheel 815 is magnetic. The wedge block 813 and the second blocking cover 812 are made of iron. A positioning groove 8111 is opened on the outer wall of the first blocking cover 811. A positioning groove 8111 is fixed on the inner wall of the second blocking cover 812. The fixed connection is equipped with a positioning strip 8121, and the positioning groove 8111 matches the positioning strip 8121. During the process of the moving block 5151 driving the drill bit 56 to descend, the mounting plate 54 and the first and second blocking covers 811 and 812 descend synchronously. The second blocking cover 812 first abuts against the upper side of the fixed seat 3. Then, during the continuous descent of the drill bit 56, the second blocking cover 812 rises relative to the first blocking cover 811. Then, the wedge block 813 presses the rotating wheel 815 to move, so that the crossbar 814 drives the positioning ring 816 to position the drill bit 56, ensuring the stability of the drill bit 56 during processing.

[0031] In addition, to improve work efficiency, multiple sets of fixed seats 3 and pneumatic clamps 4 are provided on the turntable 2. A reducer 21 and a motor 4 22 are provided on the lower side of the support plate 1. The motor 4 22 drives the reducer 21 to work, and the reducer 21 drives the turntable 2 to rotate. In this way, multiple sets of measuring ruler handles can be continuously punched and slotted.

[0032] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0033] In use, the measuring ruler handle placed on the fixed base 3 is first fixed by the pneumatic clamp 4. Then, the motor 4 22 is started, and the motor 4 22 drives the reducer 21 to work. The reducer 21 then drives the turntable 2 to rotate, transporting the fixed measuring ruler handle to the bottom of the drilling mechanism 5. Then, the screw 512 is driven to rotate by the motor 1 513. During this process, since the clamping block 5155 fixes the threaded sleeve 5152, the threaded sleeve 5152 will not rotate under the action of friction. Then, under the action of the guide rod 514, the moving block 5151 moves up and down, thereby adjusting the lifting and lowering of the drill bit 56, so that the drill bit 56 can drill holes in the measuring ruler handle. When the moving block 5151 abuts against the limit block 57, the threaded sleeve 5152 will rotate when the motor 1 513 drives the screw 512 to rotate, overcoming the friction of the clamping block 5155 on the threaded sleeve 5152 and preventing the moving block 5151 from falling too far. Meanwhile, during the drilling process, the rotation of the drill bit 56 generates centrifugal force, which drives the grinding disc 563 to slide along the arc-shaped rod 562 to the outside of the V-shaped groove 561 to a horizontal state, contacting and grinding the inner wall of the hole; after the drilling is completed, the electric telescopic rod 55 retracts, the drill bit 56 stops rotating, and the grinding disc 563 resets under the action of gravity, effectively removing burrs and cutting residues in the hole; Meanwhile, during drilling, the first baffle 811 moves down with the mounting plate 54, and the second baffle 812 automatically extends due to gravity or contact with the workpiece, surrounding the processing area of ​​the drill bit 56 and the workpiece; the negative pressure fan 84 starts, creating negative pressure in the collection box 83, confining the processing debris within the baffle and sucking it into the collection box 83 through the hose 82; after drilling is completed, the first baffle 811 moves up with the mounting plate 54, and the second baffle 812 resets, reducing debris splashing; Meanwhile, as the moving block 5151 drives the drill bit 56 to descend, the mounting plate 54 descends synchronously with the first blocking cover 811 and the second blocking cover 812. The second blocking cover 812 first abuts against the upper side of the fixed seat 3. Then, as the drill bit 56 continues to descend, the second blocking cover 812 rises relative to the first blocking cover 811. The wedge block 813 then presses the rotating wheel 815 to move, causing the crossbar 814 to drive the positioning ring 816 to position the drill bit 56, thus stabilizing the drilling of the drill bit 56. Then, the fixed measuring ruler handle is sequentially transported to the chamfering assembly 6 for chamfering and the grooving assembly 7 for grooving. Finally, the measuring ruler handle can be removed.

[0034] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
