Description

Technical Field

[0001] This utility model relates to the field of drilling devices, and in particular to an automatic material cutting type drilling device. Background Technology

[0002] With social progress and technological development, metal products are widely used in construction, industry, agriculture and various other sectors. Among the metal products used in these sectors, many types are made from tubular or rod-shaped raw materials. In the processing of these types of workpieces, it is sometimes necessary to drill holes and cut them off from the already formed workpieces to produce multiple sections of the same length of perforated workpieces.

[0003] A search revealed a Chinese patent publication number CN221817408U that discloses a steel pipe drilling device. This patent includes a base plate, a U-shaped plate fixedly mounted on the upper surface of the base plate, an electric push rod fixedly mounted on the top of the U-shaped plate, the output end of the electric push rod passing through the U-shaped plate and fixedly connected to a first connecting plate, two L-shaped rods symmetrically fixedly mounted on the side wall of the first connecting plate, and a second connecting plate fixedly connected to the two L-shaped rods, and a first motor fixedly mounted on the top of the second connecting plate. This device, through its connecting mechanism and arc-shaped clamping plate, enables the arc-shaped clamping plate to engage the steel pipe as the electric push rod pushes the first connecting plate, which in turn drives the first motor and drill rod downwards. This achieves automatic clamping of the steel pipe before drilling and automatic separation of the arc-shaped clamping plate from the steel pipe as the drill rod moves upwards after drilling. This effectively reduces the workload of workers. However, existing machining drilling devices require manual positioning and control when controlling the cut-off length of each workpiece, which affects accuracy and increases the workload of workers. Furthermore, to meet different production requirements, it is necessary to process the workpieces into different lengths. The applicability of existing equipment is poor, and its practicality needs to be improved. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] like Figure 1 — Figure 11 As shown, an automatic material-cutting drilling device includes a housing 101. A support plate 102 is bolted inside the housing 101. A material-cutting assembly 103 and a drilling assembly 104 are installed inside the housing 101. The material-cutting assembly 103 can be configured as a vertically movable rotating cutting wheel. The drilling assembly 104 is configured as a drilling bit. Both the rotating cutting wheel and the drilling bit are equipped with corresponding drive components, which is prior art. A rotating mechanism is provided inside the housing 101. The rotating mechanism includes a mounting base 201. A rotating shell 202 is rotatably connected inside the mounting base 201. The rotating shell 202 has a through groove 203 for the workpiece to be drilled. A power assembly is also provided inside the mounting base 201 for driving the rotating shell 202 to rotate relative to it within the mounting base 201, allowing drilling of the workpiece on multiple surfaces. A guiding mechanism is provided inside the shell 202. The guiding mechanism includes an active roller 301 and a passive roller 302. The punched workpiece passes through the through groove 203 and is restricted between the active roller 301 and the passive roller 302. The active roller 301 and the passive roller 302 are rotatably connected inside the rotating shell 202. The active roller 301 and the passive roller 302 are used to drive the punched workpiece to move in the discharge direction. One end of the active roller 301 is bolted to a first gear 303. One end of the passive roller 302 is bolted to a second gear 304 that meshes with the first gear 303. A power mechanism for driving the first gear 303 to rotate unidirectionally is installed inside the rotating shell 202. An installation mechanism is provided inside the rotating shell 202. The installation mechanism includes a fixing rod 501. The fixing rod 501 is bolted to the inner wall of the rotating shell 202. A fixing plate 502 is bolted to the fixing rod 501.

[0036] A translation mechanism is movably provided on the fixed rod 501. The translation mechanism includes a sliding sleeve 601, which is slidably connected to the fixed rod 501. A mounting plate 602 is slidably connected to the sliding sleeve 601.

[0037] An adjustment mechanism is movably provided on the sliding sleeve 601. The adjustment mechanism includes an adjustment block 801, which is slidably connected to the fixed rod 501. A trigger switch 802 is fixedly installed on the adjustment block 801. The trigger switch 802 is electrically connected to the cutting component 103. Each time the trigger switch 802 is pressed, the cutting component 103 is activated to cut off the punched part of the workpiece from the unpunched part, thereby producing punched workpieces of the same length. The mounting plate 602 is used to activate the trigger switch 802 when it moves to the position of the adjustment block 801. The mounting plate 602 is provided with a reversing mechanism, which is used to reciprocate the mounting plate 602 between the fixed plate 502 and the adjustment block 801.

[0038] In this embodiment, a T-shaped plate 604 is welded to one side of the mounting plate 602. The T-shaped plate 604 is slidably connected to the sliding sleeve 601. An elastic sheet 605 is bolted to the side of the T-shaped plate 604. The elastic sheet 605 is shaped with a protrusion in the middle. When the elastic sheet 605 is compressed, the protruding part in the middle is concave and accumulates a certain elastic potential energy. A U-shaped groove 606 is provided in the sliding sleeve 601. The elastic sheet 605 is movably disposed in the U-shaped groove 606. The protrusion of the U-shaped groove 606 is arranged in the opposite direction to the protrusion of the elastic sheet 605, so that the position of the mounting plate 602 on the sliding sleeve 601 is restricted to two places.

[0039] In this embodiment, the reversing mechanism includes two mating blocks 701, which are located on both sides of the mounting plate 602. A guide rod 702 is bolted to the side of the mating block 701 closest to the mounting plate 602. The guide rod 702 is slidably connected to the mounting plate 602. A spring 603 is installed between the mounting plate 602 and the mating block 701. The spring 603 is designed so that when the mounting plate 602 is in different positions, one spring 603 will always be under force, thereby causing the mating block 701 to be pressed against the corresponding first lead screw 705 or second lead screw 706.

[0040] In this embodiment, the end of the driving roller 301 away from the first gear 303 is bolted to a first lead screw 705, and the end of the driven roller 302 away from the second gear 304 is bolted to a second lead screw 706. The first lead screw 705 and the second lead screw 706 are arranged parallel to each other and have the same thread direction. When the mounting plate 602 is in different positions within the sliding sleeve 601, the two mating blocks 701 will always engage with one of the first lead screw 705 or the second lead screw 706. Since the first lead screw 705 is connected to the driving roller 301 and the second lead screw 706 is connected to the driven roller 302, and the rotation directions of the first lead screw 705 and the second lead screw 706 are opposite, when one mating block 701 engages with the first lead screw 705, the movement direction of the mounting plate 602 on the sliding sleeve 601 is opposite when it engages with the other mating block 701 and the second lead screw 706, thereby achieving the effect of reciprocating motion.

[0041] In this embodiment, two mating blocks 701 are located between the first lead screw 705 and the second lead screw 706. The mating blocks 701 are provided with semi-circular threaded grooves, which are used for the mating blocks 701 to mate with the first lead screw 705 and the second lead screw 706.

[0042] In this embodiment, a first reversing rod 703 and a second reversing rod 704 are welded onto the mounting plate 602. A first reversing block 503 is bolted to the fixing plate 502, and a second reversing block 803 is bolted to the adjusting block 801. The first reversing rod 703 and the second reversing rod 704 are respectively located at both ends of the travel stroke of the mounting plate 602. When the mounting plate 602 moves the first reversing rod 703 to the position of the first reversing block 503, the first reversing rod 703 is subjected to the squeezing action of the first reversing block 503. Similarly, when the mounting plate 602 moves the second reversing rod 704 to the position of the first reversing rod 703, the mounting plate 602 moves from the second lead screw 706 to the first lead screw 705, so that the mating block 701 cyclically engages with the first lead screw 705 and the second lead screw 706.

[0043] In this embodiment, an adjusting screw 804 is rotatably connected to the side of the adjusting block 801 away from the trigger switch 802. The adjusting screw 804 is threaded onto the rotating shell 202. By rotating the adjusting screw 804, the adjusting screw 804 pushes the adjusting block 801, which can adjust the distance between the first reversing rod 703 and the second reversing block 803. In this way, the stroke of the mounting plate 602 is adjusted. The triggering cycle of the trigger switch 802 is controlled according to the stroke of the mounting plate 602, thereby realizing the control of the interval of starting the cutting assembly 103. In this way, the length of the finally formed punched workpiece is controlled, which is convenient for producing punched workpieces of different lengths.

[0044] In this embodiment, the power mechanism includes a rotating disk 401, which is bolted to one end of the first gear 303. A connecting block 402 is bolted to the rotating disk 401. The power mechanism also includes a hydraulic rod 404, which is bolted to the rotating housing 202. The output end of the hydraulic rod 404 is bolted to a connecting seat 405. A connecting rod 406 is hinged to the connecting seat 405. A drive rod 407 is rotatably connected to the end of the connecting rod 406 away from the connecting seat 405. Each push and retraction of the output shaft of the hydraulic rod 404 constitutes one cycle. Each cycle pushes... Both the movement and retraction drive the rotating disk 401 to rotate one revolution. The rotating disk 401 drives the active roller 301 to rotate through the first gear 303, and the first gear 303 drives the passive roller 302 to rotate through the second gear 304, so that the workpiece to be drilled makes periodic translational movements, which facilitates the drilling assembly 104 to drill holes. The connecting block 402 is provided with a slanted groove 403, and the drive rod 407 is movably set in the slanted groove 403. The setting of the slanted groove 403 ensures that the connecting rod 406 pushes the connecting block 402 to rotate in the same direction through the drive rod 407, so as to ensure that the workpiece to be drilled moves towards the drilling assembly 104.

[0045] In this embodiment, two guide rollers 305 are rotatably connected inside the rotating shell 202. A synchronous belt 306 is sleeved between the two guide rollers 305 and the active roller 301 and the passive roller 302. The horizontal movement of the punched workpiece is ensured by the guidance of the active roller 301, the passive roller 302 and a set of guide rollers 305, thereby improving the punching quality and the straightness of the cut, and improving the production quality.

[0046] Working principle: When using this device, firstly, the adjusting screw 804 is rotated according to the required cut-off length of the workpiece. The adjusting screw 804 pushes the adjusting block 801 to move, controlling the distance between the adjusting block 801 and the mounting plate 602. In this way, the positions of the first reversing rod 703 and the second reversing block 803 change. The cut-off length of each section of the workpiece is determined by the diameter of the active roller 301 and the pitch of the first lead screw 705 and the second lead screw 706. In actual production, it can be calculated that when drilling begins, the worker pushes the unprocessed workpiece from one side of the rotating shell 202 into the through groove 203. After passing through the active roller 301, the passive roller 302, and the guide roller 305, it moves towards the cutting assembly 103. At this time, the hydraulic rod 404 is activated, and the hydraulic pressure... The output end of the rod 404 pushes the connecting seat 405, which in turn drives the connecting rod 406 to move. The connecting rod 406 drives the connecting block 402 to rotate via the drive rod 407. The connecting block 402 drives the first gear 303 to rotate via the rotating disk 401. The first gear 303 drives the passive roller 302 to rotate via the meshing second gear 304, so that the active roller 301 and the passive roller 302 rotate together in opposite directions. Each time the output end of the hydraulic rod 404 is pushed out and retracted, the active roller 301 rotates one revolution, allowing the workpiece to travel a certain distance and making the drilling uniform. When drilling is required on other surfaces, the power component in the mounting base 201 causes the rotating shell 202 to rotate at a certain angle, so that the other surfaces of the workpiece are aligned with the drill bit of the drilling assembly 104, which facilitates multi-face drilling.

[0047] During the rotation of the driving roller 301 and the driven roller 302, the driven roller 302 drives the second lead screw 706 to rotate, and the driving roller 301 drives the first lead screw 705 to rotate. Since the protrusions of the U-shaped groove 606 and the elastic plate 605 are arranged in opposite directions, and with the two springs 603, when the elastic plate 605 is located within the U-shaped groove 606 near the first reversing rod 703, the spring 603 near the first reversing rod 703 applies a certain force to the mating block 701, causing the mating block 701 to engage with the first lead screw 705. When the first reversing rod 703 is squeezed by the first reversing block 503, due to the inclined surface of the first reversing block 503, the first reversing rod... 703 moves away from the first lead screw 705. During this process, the first reversing rod 703 drives the mounting plate 602 to move away from the first lead screw 705. The mounting plate 602 drives the elastic piece 605 to move within the U-shaped groove 606 via the T-shaped plate 604, gradually loosening the spring 603 that was pressing the mating block 701 against the first lead screw 705. However, this does not affect the mating of the mating block 701 with the first lead screw 705. Until the elastic piece 605 passes through the maximum protrusion of the U-shaped groove 606, the elastic potential energy accumulated in the elastic piece 605 is released. At this time, the elastic piece 605 pushes the mounting plate 602 to move, causing the mating block 701, which is away from the first lead screw 705, to move towards the second lead screw. The mounting plate 602 moves in the direction of 706, compressing the corresponding spring 603 and pressing the mating block 701 against the second lead screw 706. Since the rotation directions of the first lead screw 705 and the second lead screw 706 are opposite, the movement direction of the mounting plate 602 changes. At the moment this change occurs, the trigger switch 802 is squeezed by the mounting plate 602, thereby causing the cutting assembly 103 to cut the workpiece being drilled. Thus, when the mounting plate 602 is in different positions, there will always be a spring 603 under force, thereby causing the mating block 701 to be pressed against the corresponding first lead screw 705 or second lead screw 706. During the drilling process, when the mounting plate 602 drives the first reversing rod 703 to move to... When the first reversing block 503 is in position, the first reversing rod 703 is squeezed by the first reversing block 503. Similarly, when the mounting plate 602 drives the second reversing rod 704 to the position of the first reversing rod 703, the mounting plate 602 moves from the second lead screw 706 to the first lead screw 705, so that the mating block 701 cyclically engages with the first lead screw 705 and the second lead screw 706. The mounting plate 602 between the first lead screw 705 and the second lead screw 706 moves back and forth due to the setting of the mating block 701, thereby realizing the periodic cutting of the punched workpiece. Furthermore, since the position of the adjusting block 801 is adjustable, the stroke of the reciprocating movement is also changed to obtain punched workpieces of different lengths.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
