DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] See also Figure 1 , Figure 2 as well as Figure 3 The present embodiment provides a steel member drilling device, including a support platform 10, a positioning assembly 20, a lifting assembly 30, a drilling assembly 40 and a grinding assembly 50. The positioning assembly 20 is installed on the upper part of the support platform 10, and is used to position the steel plate to be drilled. An L-shaped supporting plate 102 is fixedly provided on the upper edge of the support platform 10. The drilling assembly 40 is arranged on the inner side of the L-shaped supporting plate 102. The lifting assembly 30 is installed on the inner top wall of the L-shaped supporting plate 102, and is used to drive the drilling assembly 40 to move up and down. When the drilling assembly 40 moves down, the steel plate is drilled. The grinding assembly 50 is arranged on the drilling assembly 40. When the drilling assembly 40 finishes drilling the steel plate, the grinding assembly 50 is used to grind the upper and lower edges of the holes drilled on the steel plate to remove protrusions and burrs.

[0032] When it is necessary to drill holes in the steel plate, the steel plate to be drilled can be placed on the upper part of the support table 10, and then the positioning assembly 20 is used to position the steel plate. After the steel plate is positioned, the lifting assembly 30 drives the drilling assembly 40 to move downward, and the drilling assembly 40 acts on the positioned steel plate when moving downward to drill holes in the steel plate. After the drilling is completed, the grinding assembly 50 on the drilling assembly 40 grinds the upper and lower edges of the drilled holes, thereby removing the protrusions and burrs generated on the upper and lower edges of the holes during drilling, thereby improving the drilling effect.

[0033] See also Figure 1 In one embodiment, the lifting assembly 30 includes a hydraulic cylinder 301 and a lifting plate 303, the hydraulic cylinder 301 is fixedly mounted on the inner top wall of the L-shaped support plate 102, and the lifting plate 303 is arranged at the output end of the hydraulic cylinder 301. The drilling assembly 40 includes a motor 401 and a drill rod 402, the motor 401 is fixedly mounted at the bottom of the lifting plate 303, and the drill rod 402 is installed at the output end of the motor 401.

[0034] After the positioning assembly 20 positions the steel plate to be drilled on the upper part of the support platform 10, the motor 401 drives the drill rod 402 to rotate, and at the same time the hydraulic cylinder 301 extends to drive the lifting plate 303 to move downward. When the lifting plate 303 moves downward, it drives the motor 401 and the drill rod 402 to move downward synchronously. When the drill rod 402 moves downward, it acts on the steel plate, thereby drilling the steel plate.

[0035] See also Figure 1 In one embodiment, a connecting rod 302 is fixedly provided on the side wall of the lifting plate 303, a vertically distributed slide rail 103 is fixedly provided on the side wall of the L-shaped support plate 102, a slider 104 is slidably provided on the slide rail 103, and one end of the connecting rod 302 away from the lifting plate 303 is connected to the slider 104.

[0036] When the lifting plate 303, the motor 401 and the drill rod 402 move downward, the sliding cooperation between the slider 104 and the slide rail 103 can provide guidance for the downward movement of the lifting plate 303, the motor 401 and the drill rod 402, thereby improving the accuracy of drilling holes in the steel plate.

[0037] See also Figure 4 as well as Figure 5 In one embodiment, an inner cavity 404 is provided inside the drill rod 402, a chute 403 communicating with the inner cavity 404 is provided on the side wall of the drill rod 402, the chute 403 is vertically distributed, a first chute 405, a second chute 406 and a vertical groove 407 are provided on the wall of the inner cavity 404, two groups of the first chute 405 and the second chute 406 are provided, two groups of the first chute 405 are arranged on one side of the upper part of the vertical groove 407 and communicated with the upper end of the vertical groove 407, two groups of the second chute 406 are arranged on one side of the lower part of the vertical groove 407 and communicated with the lower end of the vertical groove 407, The grinding assembly 50 includes a limit block 501, an elastic member 502 and a grinding block 503. The limit block 501 is arranged inside the inner cavity 404. Two groups of sliding pins 504 are fixedly arranged on the side wall of the limit block 501. The two groups of sliding pins 504 are vertically distributed and extend into the vertical groove 407. One end of the elastic member 502 is connected to the cavity wall of the inner cavity 404, and the other end is connected to the limit block 501 to provide elastic support for the limit block 501. One end of the grinding block 503 is fixedly connected to the limit block 501, and the other end extends horizontally from the slide groove 403 to the outside of the drill rod 402.

[0038] Initially, the two sets of sliding pins 504 are located inside the vertical groove 407, and the elastic member 502 provides elastic support for the limit block 501, so that the limit block 501 abuts against the wall of the inner cavity 404, and the grinding block 503 extends to the outside of the drill rod 402. As the drill rod 402 rotates and moves downward, the drill rod 402 can drive the grinding block 503 to rotate synchronously. After the drill rod 402 moves downward and penetrates the steel plate, the bottom of the grinding block 503 acts on the upper surface of the steel plate and rotates compared to the upper surface of the steel plate, thereby grinding the protrusions and burrs at the upper edge of the hole drilled on the steel plate. As the drill rod 402 continues to move downward, the grinding block 503 is pressed and slides up along the inner side of the slide groove 403, and the grinding block 503 drives the limit block 501 along the inner When the two sets of sliding pins 504 slide up to the upper end of the vertical groove 407, the two sets of sliding pins 504 slide into the two sets of first inclined grooves 405 and slide up along the two sets of first inclined grooves 405, thereby driving the limit block 501 to move into the inner cavity 404. The limit block 501 pulls the grinding block 503 to move the grinding block 503 into the inner cavity 404. When the grinding block 503 is completely moved into the inner cavity 404, the grinding block 503 moves to the bottom of the steel plate as the drill rod 402 moves downward. At this time, the elastic member 502 pushes the limit block 501 to make the two sets of sliding pins 504 slide down along the first inclined groove 405 and slide to the upper end of the vertical groove 407. Inside the groove 407, the limit block 501 drives the grinding block 503 to move in the opposite direction, so that the grinding block 503 extends from the slide groove 403 to the outside of the drill rod 402 again, and then the hydraulic cylinder 301 retracts to drive the lifting plate 303, the motor 401 and the drill rod 402 to move upward. When the drill rod 402 moves upward, it drives the grinding block 503 to move upward synchronously. When the grinding block 503 moves upward, it acts on the lower surface of the steel plate and rotates compared to the lower surface of the steel plate to grind the protrusions and burrs at the lower edge of the hole drilled on the steel plate. As the drill rod 402 continues to move upward, the grinding block 503 is pressed and slides down along the inside of the slide groove 403. The grinding block 503 drives the limit block 501 to move downward along the inner cavity 404, and the two sets of sliding pins 504 move along the vertical groove 407 slides down, and when the two groups of sliding pins 504 slide down to the bottom of the vertical groove 407, the two groups of sliding pins 504 slide into the two groups of second inclined grooves 406 and slide down along the two groups of second inclined grooves 406, thereby driving the limit block 501 to move into the inner cavity 404 again, and the limit block 501 pulls the grinding block 503 again to make the grinding block 503 move into the inner cavity 404, and the grinding block 503 moves into the inner cavity 404 again. After the grinding block 503 moves into the inner cavity 404, as the drill rod 402 continues to move upward, the grinding block 503 moves to the top of the steel plate, and the drill rod 402 withdraws from the drilled hole, thereby completing the drilling of the steel plate and the automatic grinding of the protrusions and burrs on the upper and lower edges of the drilled hole.

[0039] In one embodiment, the elastic member 502 may be a spring or a metal spring, which is not limited here.

[0040] When the grinding block 503 moves into the inner cavity 404, the end of the grinding block 503 away from the stop block 501 will abut against the inner wall of the hole and move down along the inner wall of the hole. Therefore, the grinding block 503 is easy to scratch the inner wall of the hole. Figure 4 as well as Figure 5 In one embodiment, the end of the grinding block 503 away from the limiting block 501 is in an arc-shaped structure. By designing the end of the grinding block 503 away from the limiting block 501 to be in an arc-shaped structure, it can be effectively prevented from scratching the inner wall of the hole.

[0041] See also Figure 1 In one embodiment, the positioning assembly 20 includes an L-shaped positioning plate 201, a pressure plate 202, a screw 203 and a handle 204. The L-shaped positioning plate 201 is fixedly arranged on the upper part of the support platform 10. The screw 203 vertically penetrates the L-shaped positioning plate 201 and is threadedly engaged with the L-shaped positioning plate 201. The pressure plate 202 is arranged at the bottom of the screw 203, and the handle 204 is arranged on the upper part of the screw 203.

[0042] By placing the steel plate to be drilled on the inner side of the L-shaped positioning plate 201, and then turning the handle 204, the screw rod 203 is driven to rotate. When the screw rod 203 rotates, it moves downward compared to the L-shaped positioning plate 201, thereby driving the pressure plate 202 to move downward. The pressure plate 202 presses the steel plate against the upper part of the support platform 10 to achieve the positioning of the steel plate.

[0043] See also Figure 1 as well as Figure 3 In one embodiment, a through hole 105 is provided on the support platform 10 for the drill rod 402 to pass through, and a plurality of columns 101 are fixedly provided on the bottom edge of the support platform 10 .

[0044] In the embodiment of the present invention, when it is necessary to drill a steel plate, the steel plate to be drilled can be placed on the upper part of the support table 10, and then the positioning assembly 20 is used to position the steel plate. After the steel plate is positioned, the lifting assembly 30 drives the drilling assembly 40 to move downward, and the drilling assembly 40 acts on the positioned steel plate when moving downward to drill the steel plate. After the drilling is completed, the grinding assembly 50 on the drilling assembly 40 grinds the upper and lower edges of the drilled hole, thereby removing the protrusions and burrs on the upper and lower edges of the hole during drilling, thereby improving the drilling effect. Compared with the prior art, automatic drilling of the steel plate can be realized, and after drilling, the protrusions and burrs at the upper and lower edges of the drilled hole can also be ground, thereby improving the drilling effect and drilling quality.

[0045] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
