Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, and in particular to a drilling equipment. Background Art

[0002] The general drilling equipment for the bottom plate of the towel rack is manually fed. When the machine completes a drilling operation, it needs to feed the material manually once.

[0026] The present invention provides a drilling device. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present invention. In addition, "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0028] In the present invention, the "drilling station" refers to the position on the drilling platform 41 for placing the workpiece to be drilled. The "loading station" refers to the area in the loading mechanism 2 where the workpiece movement track is formed.

[0029] See also Figure 1-7The present invention provides a drilling device, including a frame 1, a loading mechanism 2, a feeding mechanism 3 and a drilling mechanism 4 arranged on the frame 1, and also including a controller; the feeding mechanism 3 is used to transfer the workpiece A in the loading mechanism 2 to the drilling mechanism 4, the loading mechanism 2 includes a loading component 21 and a limiting rod 22, and the limiting rod 22 is not less than 4 and is respectively arranged around the loading station of the workpiece A to limit the rising trajectory of the workpiece A, and the loading component 21 is used to lift the workpiece A; the controller is electrically connected to the loading mechanism 2, the feeding mechanism 3 and the drilling mechanism 4 respectively.

[0030] The drilling equipment is provided with a separate feeding mechanism 2 and an independent loading station, which avoids the potential safety hazards caused by feeding directly into the drilling mechanism 4 and reduces the damage caused by accidents; moreover, multiple workpieces A can be stored in the loading station, and the operator does not need to repeat the feeding work for a long time, which greatly reduces the probability of accidents. The feeding mechanism 2, the feeding mechanism 3 and the drilling mechanism 4 are respectively controlled by the controller, with a high degree of automation and improved control accuracy. The controller includes but is not limited to a PLC controller. The size of the workpiece loading station is limited by the limit rod 22, so that the workpiece can rise vertically, ensuring that the feeding mechanism 3 can accurately absorb the workpiece A.

[0031] The number of the limit rods 22 can be set according to the specifications of the workpiece in actual application. For long strip-shaped workpieces, in one embodiment, the number of the limit rods 22 is 6, two of which are respectively arranged on both sides of the length direction of the workpiece loading station, and one is respectively arranged on the short side of the workpiece loading station.

[0032] In one embodiment, the lower end of the limit rod 22 is fixed to the frame 1 through a strip hole and a bolt, and the distance between the limit rods 22 can be adjusted according to the specifications of the workpiece, thereby adjusting the size of the loading station so that the cross-section of the loading station is adapted to the specifications of the workpiece.

[0033] Specifically, the loading assembly 21 includes two feeding screws 211, a first driving mechanism, a support block 212 and a support plate 213; the two feeding screws 211 are respectively arranged on opposite sides of the loading station, the two ends of the support block 212 are respectively fixedly connected to the two feeding screws 211, the support plate 213 is arranged on the support block 212, and is used to support the workpiece, and the first driving mechanism (not shown in the figure) is used to drive the lifting of the feeding screw 211, so as to realize the lifting of the workpiece. The support plate 213 can be replaced according to the different specifications of the workpiece to achieve the effect of adapting to the workpiece, so that it can better cooperate with the operation and improve the positioning accuracy. In one embodiment, the two feeding screws 211 are respectively arranged in the middle of the two sides of the loading station in the degree direction, and the support block 212 is in a "cross" shape, which can better maintain the balance of the workpiece and improve the stability of loading, and the limit rods 22 are respectively arranged on both sides of the feeding screw 211 without interfering with each other.

[0034] Preferably, the feeding mechanism 2 also includes a sensor 23, and the sensor 23 includes multiple sensors, which are respectively arranged at the upper ends of the limit rod 22, and are used to sense whether there is a workpiece exceeding the height of the limit rod 22, to prevent the feeding screw 211 from rising excessively and causing the workpiece to spill, thereby avoiding waste of workpieces and affecting work efficiency.

[0035] The frame 1 includes a bottom plate 11, a support frame 12, a beam 13 and a workbench 14. The support frame 12 is arranged on the bottom plate 11, and its upper end is connected to one end of the beam 13, and the other end of the beam 13 is connected to the upper part of the workbench 14. The feeding mechanism 2 is arranged on the bottom plate 11, and is located between the support frame 12 and the workbench 14. The support frame 12 is used to support and fix the beam 13, and by fixing the feeding mechanism 3 under the beam 13, the feeding mechanism 3 will not be blocked by the support frame 12 when conveying the workpiece.

[0036] In one embodiment, the drilling mechanism 4 includes a drilling platform 41, a limiting mechanism 42, a shifting mechanism 43, a pushing mechanism 44, a movable limiting mechanism 45 and a plurality of drill bits 46. A working platform 141 is provided in the middle of the workbench 14. The drilling platform 41, the movable limiting mechanism 45 and the shifting mechanism 43 are respectively arranged on the working platform 141. The movable limiting mechanism 45 is arranged on one side of the drilling station to limit the forward movement of the workpiece. The shifting mechanism 43 is used to drive the drilling platform 41 to move forward and backward. The limiting mechanism 42 is arranged on the drilling platform 41 to limit the workpiece on the drilling station. The pushing mechanism 44 is arranged on the drilling platform 41 to push the workpiece on the drilling station. The plurality of drill bits 46 are arranged above the drilling station, fixed on the upper part of the workbench 14, and arranged along the length direction of the drilling station.

[0037] The drilling platform 41 is slidably connected to the working platform 141 through a slider assembly fixed at its bottom and on the working platform 141. The shifting mechanism 43 is controlled by a controller to push the drilling platform 41 to move forward and backward, so that when the workpiece needs to drill multiple rows of holes, there is no need to manually adjust the position, and the positioning is more accurate. The limiting mechanism 42 and the mobile limiting mechanism 45 work together to limit the position of the workpiece when drilling, prevent the workpiece from shifting and affecting the quality of the drilling, and improve safety. Preferably, the position of the limiting mechanism 42 and the mobile limiting mechanism 45 can be adjusted to meet the production needs of workpieces of different specifications. In this embodiment, the shifting mechanism 43 is set in two, respectively arranged on both sides of the length direction of the drilling platform 41, which is more conducive to the smooth movement of the drilling platform 41. The mobile limiting mechanism 45 is also set in two, respectively arranged on both sides of the midpoint of the long side of the drilling platform 41. For a long strip of workpiece, this setting can make the workpiece balanced. The pushing mechanism 44 is set just behind the midpoint of the long side of the drilling station, which is convenient for pushing the workpiece in a balanced manner.

[0038] Furthermore, the pushing mechanism 44 and the shifting mechanism 43 are preferably double-axis cylinders, which operate smoothly and have low energy consumption; of course, they can also be electric push rods, etc.

[0039] In one embodiment, the drill bits 46 include six, which are arranged in a row along the length direction of the workpiece. By connecting to a controller and being uniformly controlled by the controller, multiple drill bits can be operated simultaneously. Compared with multiple drillings with a single drill bit, the control level is simplified, and the work efficiency and operational stability are improved.

[0040] In one embodiment, the limiting mechanism 42 includes a limiting block 421, a first limiting mechanism 422, and a second limiting mechanism 423. The second limiting mechanism 423 is arranged on one side of the drilling station and is arranged opposite to the movable limiting mechanism 45; the limiting block 421 and the first limiting mechanism 422 are respectively arranged on the other two sides of the drilling station. The positions of the limiting block 421 and the first limiting mechanism 422 are adjustable to accommodate workpieces of different lengths; the limiting block 421, the first limiting mechanism 422, the second limiting mechanism 423, and the movable limiting mechanism 45 are respectively abutted against the four side walls of the workpiece to effectively prevent the workpiece from shifting. The first limiting mechanism 422 and the second limiting mechanism 423 include but are not limited to one of a dual-axis cylinder and an electric push rod.

[0041] Furthermore, the limit block 421 includes a limit portion 4211 and a mounting portion 4212. The mounting portion 4212 is provided with a strip hole arranged along the length direction of the drilling station, and the limit block 421 is fixed to the drilling platform 41 through the strip hole and the bolt. By adjusting the position of the bolt in the strip hole, the distance between the limit block 421 and the first limit mechanism 422 can be adjusted to adapt to workpieces of different lengths. Through the matching mode of the bolt and the strip hole, disassembly is convenient, and the position adjustment of the limit block 421 is convenient.

[0042] The movable limiting mechanism 45 includes a blocking rod 451 and a fourth driving mechanism 452. The front side of the drilling platform 41 along the workpiece conveying direction is provided with a plurality of grooves 411. The blocking rod 451 is engaged with the grooves 411. The lower part of the blocking rod is drivingly connected with the fourth driving mechanism 452. The fourth driving mechanism 452 is arranged on the workbench 14 and is electrically connected with the controller. The upper end surface of the blocking rod 451 protrudes from the upper surface of the drilling platform 41 to ensure that the workpiece on the drilling station can be blocked; the depth of the groove 411 is configured to enable the blocking rod 451 to abut against the workpiece on the hole turning station. The fourth driving mechanism 452 can drive the blocking rod 451 to rotate along the connection between the two to a position lower than the bottom of the drilling platform 41, so that when the pushing mechanism 44 pushes the workpiece out of the drilling station, the blocking rod 451 does not block it. The blocking rod 451 can be driven by the fourth driving mechanism 452 to move away from or closer to the orthographic projection of the drill bit 46 on the drilling station, which is suitable for the movement of the drilling platform 41 when the workpieces of different widths need to be processed or multiple rows of holes need to be processed on the workpieces.

[0043] In one embodiment, the feeding mechanism 3 includes a second driving mechanism 31, a third driving mechanism 32, a first mounting seat 33, a second mounting seat 34 and a suction cup 35, wherein the second mounting seat 34 and the suction cup 35 respectively include a plurality of suction cups 35, and the suction cup 35 is arranged at the bottom of the second mounting seat 34, and is used to absorb the workpiece in the feeding mechanism 2, one end of the second mounting seat 34 is connected to the first mounting seat 33, the lower end of the third driving mechanism 32 is connected to the first mounting seat 33, and is used to drive the lifting of the first mounting seat 33, and the second driving mechanism 31 is connected to the bottom of the crossbeam 13, and is used to drive the third driving mechanism 32 to move back and forth along the conveying direction of the workpiece. The number of the second mounting seat 34 and the suction cup 35 can be set according to the length of the workpiece to ensure that the workpiece can be transferred smoothly. The suction cup 35 is a negative pressure suction cup 35, which improves its adsorption capacity for the workpiece. The bottom surface of the first mounting seat 33 is provided with a mounting groove along the length direction, and the second mounting seat 34 is fixed in the slide groove. The bottom of the second mounting seat 34 is also provided with a mounting groove along the length direction, and the suction cup 35 is fixed in the mounting groove. By adjusting the position of the second mounting seat 34 in the slide groove of the first mounting seat 33 and the position of the suction cup 35 in the mounting groove of the second mounting seat 34, the left-right and front-back position of the suction cup 35 can be adjusted to meet the needs of transferring different workpieces. The second driving mechanism 31 includes but is not limited to one of a stroke cylinder and an electric push rod, and the third driving mechanism 32 includes but is not limited to one of a dual-axis cylinder and an electric push rod.

[0044] Preferably, the second mounting seat 34 and the suction cup 35 include a plurality of them, and the plurality of the second mounting seats 34 are arranged in a direction perpendicular to the moving track of the feeding mechanism 3, and the suction cup 35 is staggered with the drill bit 46. Providing a plurality of second mounting seats 34 and suction cups 35 can improve the adsorption force of the suction cup 35 on the workpiece, improve the feeding stability and safety of the feeding mechanism 3, and the suction cup 35 and the drill bit 46 are staggered, do not interfere with each other, and avoid collision between the suction cup 35 and the drill bit 46 when transferring the workpiece.

[0045] When the equipment is working, the operator first adds the workpiece to be drilled into the feeding mechanism 2 and stacks them neatly. The equipment is turned on, and the controller controls the first drive mechanism to drive the feeding screw 211 to drive the workpiece to a suitable position, the second drive mechanism 31 drives the first drive mechanism to the top of the loading station, and the third drive mechanism 32 drives the suction cup 35 to descend until the suction cup 35 can contact the upper surface of the workpiece. The suction cup 35 sucks up a workpiece and is driven to rise by the third drive mechanism 32. The second drive mechanism 31 approaches the drilling mechanism 4. After reaching the preset position, the suction cup 35 stops working and places the workpiece in the drilling station, and then the second drive mechanism 31 is reset. The movable ends of the first limiting mechanism 422 and the second limiting mechanism 423 are pushed forward respectively; at the same time, the stop rod 451 of the movable limiting mechanism 45 rises until it respectively contacts the workpiece, fixing the workpiece on the drilling station; then the drill bit 46 is pressed down to perform the drilling operation, and after the drilling is completed, the drill bit 46 is reset. When multiple rows of holes need to be drilled, the shift mechanism 43 pushes the drilling platform 41 to a preset position, and the drill bit 46 descends again to perform the drilling operation, and the processing of multiple rows of holes is repeated in this way. When all drilling operations are completed, the movable limit mechanism 45 descends to a position below the drilling platform 41, and the push mechanism 44 is started to push the workpiece out of the drilling platform 41, so that the workpiece falls into the collection box, and then resets. The movable limit mechanism 45 returns to the initial state, completing a processing process. Except for placing the workpiece at the loading station, the above operations are all automatically completed under the control of the controller.
