Description

Technical Field

[0001] The present invention relates to the technical field of metal product processing, and more specifically, it relates to a drilling device for metal product processing. Background Art

[0002] In the metal product processing process, according to production requirements, drilling operations need to be performed on metal products. Generally, the metal products to be processed are fixed on the clamping device of the drilling equipment to ensure that they do not move or shake during the drilling process, and then the drilling mechanism on the corresponding equipment is used to perform drilling operations on the metal products.

[0003] As Figure 1 shown, it is the product to be processed in this application. This product is a columnar metal product, and both end faces and the side surface of this product need to be drilled, specifically end face holes and side surface holes. The clamping device on the existing drilling equipment for fixing metal products, when fixing a columnar metal product as Figure 1 shown for subsequent drilling processing, usually fixes the columnar metal product horizontally for drilling on the side surface of the columnar metal product. When it is necessary to drill the end face of the columnar metal product, it is necessary to disassemble the metal product and fix it vertically to facilitate the drill bit to drill on the end face of the metal product. At this time, fixing the metal product vertically may require replacing and installing another clamping device that can fix the columnar metal product vertically, or installing and fixing the columnar metal product that needs end face drilling to another drilling equipment that can fix the columnar metal product vertically for end face drilling. The operation is inconvenient and the drilling efficiency is low.

[0004] The invention patent with application number 202211608714.1 discloses a metal product processing device and processing method. By rotatably arranging a rotating table on a base, and arranging a plurality of fixing stations for fixing metal materials on the rotating table. After the drilling of the metal product on one fixing station is completed, the drilling of the metal product on the next fixing station can be directly carried out without waiting for the time of removing and reinstalling the metal product from the fixing station, effectively improving the connection of metal product drilling and the processing efficiency of metal products. However, when it is necessary to drill the side surface and end face of the columnar metal product according to production needs, it is not necessary to replace the clamping unit or install and fix the metal product to be drilled to another equipment, and it can drill the side surface and end face of the columnar metal product at the same time, with convenient operation and improved drilling efficiency.

Detailed implementation mode

[0027] Refer to Figures 1 to 5 A further description is given to the embodiments of the present invention.

[0028] A drilling device for metal product processing, including a drilling machine, on which there are a drilling mechanism 1 2 for drilling the side of the metal product, a drilling mechanism 2 3 for drilling the end face of the metal product, and a workbench 1 corresponding to the drilling mechanism 1 2. A clamping unit for fixing the metal product, a loading unit for loading, and a blanking unit for blanking are installed on the workbench 1.

[0029] The clamping unit includes a base 4 movably connected to the workbench 1, two clamping seats 5 for fixing columnar metal products, and a first hydraulic cylinder 6 installed on the base 4. The two clamping seats 5 are respectively installed on both sides of the base 4, and the two clamping seats 5 cooperate to form a clamping space 001 corresponding to the drilling mechanism 1 2. One clamping seat 5 is movably connected to the base 4 and connected to the output end of the cylinder, so that when the first hydraulic cylinder 6 works, it drives this clamping seat 5 to approach the other clamping seat 5, making both ends of the metal product contact with the two clamping seats 5 respectively for fixing the metal product. A drilling channel 7 corresponding to the drilling mechanism 2 3 and a positioning groove 8 communicating with the drilling channel 7 are opened on the clamping seat 5. A baffle 20 corresponding to the material collection frame 9 is movably connected to the clamping seat 5, and a second spring 21 connected to the clamping seat 5 is installed on the baffle 20.

[0030] The loading unit includes a loading box 13 for storing metal products to be processed, two limiting plates 14 respectively installed on both sides of the first channel 12, and a second hydraulic cylinder 15 installed on the loading box 13. The two limiting plates 14 cooperate to form a loading space 002 corresponding to the clamping space 001. The loading space 002 is communicated with the first channel 12. Both ends of the loading box 13 are installed on the two limiting plates 14. An outlet 16 corresponding to the loading space 002 is opened on the loading box 13. A limiting piece 18 is movably connected to the outlet 16, and a first spring 19 connected to the limiting piece 18 is installed on the outlet 16 to prevent the metal products in the loading box 13 from falling out of the outlet 16 without thrust. The output end of the second hydraulic cylinder 15 passes through the loading box 13 and corresponds to the outlet 16, and the output end of the hydraulic cylinder is movably connected to the loading box 13, so that the second hydraulic cylinder 15 can work to push the metal products in the loading box 13 out of the outlet 16 and fall into the loading space 002. A limiting groove 17 communicated with the loading space 002 is opened on the limiting plate 14. The limiting groove 17 corresponds to the positioning groove 8, so that the end of the metal product entering the loading space 002 can enter the positioning groove 8 after passing through the limiting groove 17.

[0031] The unloading unit includes a receiving frame 9 corresponding to the clamping space 001, a rotating motor 10 installed on the workbench 1, and a dial rod 11 installed on the output end of the rotating motor 10. A first channel 12 corresponding to the clamping space 001 is opened on the base 4, and a second channel 121 communicated with the first channel 12 is opened on the tabletop of the workbench 1, so that the rotating motor 10 drives the dial rod 11 to rotate, and the dial rod 11 passes through the second channel 121 and the first channel 12 and extends into the clamping space 001 to push the metal products that have completed drilling into the receiving frame 9.

[0032] Working principle: Place the columnar metal product to be processed into the feeding box 13. The second hydraulic cylinder 15 works to push the metal product in the feeding box 13 out from the discharge port 16 and fall into the feeding space 002 formed by the cooperation of two limiting plates 14. The setting of the limiting piece 18 on the discharge port 16 prevents the metal product in the feeding box 13 from falling out of the discharge port 16 when the second hydraulic cylinder 15 does not push. When the second hydraulic cylinder 15 pushes the metal product, the metal product in contact with the limiting piece 18 compresses the first spring 19, so that when the limiting piece 18 moves, the discharge port 16 is completely opened, facilitating the smooth fall of the metal product from the discharge port 16 into the feeding space 002. The two limiting plates 14 limit the two ends of the metal product entering the feeding space 002. The metal product entering the feeding space 002 rolls on the base 4, and the two ends of the metal product roll in the limiting grooves 17 of the two limiting plates 14. As the metal product rolls, the metal product enters the clamping space 001. Since the limiting groove 17 corresponds to the positioning groove 8, the end of the metal product in the limiting groove 17 rolls into the positioning groove 8, preventing the position deviation of the metal product during rolling from affecting subsequent processing. At this time, the first hydraulic cylinder 6 works to drive one clamping seat 5 to approach the other clamping seat 5, so that the two ends of the metal product are in contact with the inner wall of the positioning groove 8, and then the two clamping seats 5 clamp and fix the metal product in the clamping space 001. With the setting of the baffle 20 on the clamping seat 5, it is prevented that the metal product entering the clamping space 001 continues to roll and rolls out of the clamping space 001, affecting the clamping and fixing of the metal product by the clamping seat 5.

[0033] The drilling mechanism 2 drills the side of the metal product fixed in the clamping space 001. At the same time, the drilling mechanism 3 drills the end face of the metal product fixed in the clamping space 001 through the drilling channel 7. The base 4 moves on the workbench 1 in cooperation with the base 4 moving towards the receiving frame 9, so that the drilling mechanism 2 and the drilling mechanism 3 drill the multiple metal products fixed in the clamping space 001 in sequence, improving the connection of the drilling operation of the multiple metal products and the drilling efficiency. After the drilling of the metal product in the clamping space 001 is completed, the first hydraulic cylinder 6 works to drive one clamping seat 5 away from the other clamping seat 5. In cooperation with the rotation of the rotating motor 10 driving the lever 11 to rotate, during the rotation of the lever 11, the lever 11 passes through the second channel 121 and the first channel 12 and extends into the clamping space 001 to push the drilled metal product. At this time, the metal product in contact with the baffle 20 squeezes the baffle 20, causing the second spring 21 to elongate and driving one end of the baffle 20 away from the metal product, facilitating the removal of the drilled metal product from the clamping space 001. Furthermore, it is convenient for the lever 11 to push the drilled metal product into the receiving frame 9 during rotation, realizing the automatic collection of the drilled metal products, saving manpower and improving the drilling efficiency. Finally, when drilling the side and end faces of the columnar metal product according to production needs, it is not necessary to replace the clamping unit or install and fix the metal product to be drilled on another device, nor is it necessary to disassemble and reinstall the metal product to be drilled to change the drilling position. It can drill the side and end faces of the columnar metal product at the same time, with convenient operation and improved drilling efficiency.

[0034] On both inner walls of the feeding box 13, a guiding inclined plate 22 is respectively installed. The feeding box 13 is provided with a through hole 23 movably connected to the output end of the second hydraulic cylinder 15. A push plate 24 that moves in the feeding box 13 is installed on the output end of the second hydraulic cylinder 15. The length of the push plate 24 corresponds to the length of the metal product. The push plate 24 corresponds to the metal product in the feeding box 13, so that the second hydraulic cylinder 15 works to drive the push plate 24 to move and push the metal product out of the discharge port 16. The setting of the push plate 24 will not cause the metal product to be skewed when the push plate 24 pushes the metal product out of the discharge port 16, preventing the position of the metal product from shifting when it falls into the feeding space 002 and affecting the subsequent drilling effect. Since multiple metal products stored in the feeding box 13 are stacked, the setting of the guiding inclined plate 22 prevents the upper metal products in the feeding box 13 from pressing on the lowermost metal product in the box, resulting in the second hydraulic cylinder 15 being unable to smoothly push the lowermost metal product out of the discharge port 16. And after the second hydraulic cylinder 15 pushes a metal product out of the discharge port 16, an upper metal product in the feeding box 13 can smoothly fall onto the inner wall of the bottom of the feeding box 13 corresponding to the push plate 24 for replenishment, facilitating the next feeding and improving the drilling efficiency.

[0035] The base 4 includes a feeding inclined plane 401, a clamping plane 402, and a discharging inclined plane 403. The first channel 12 is disposed on the feeding inclined plane 401, the clamping plane 402, and the discharging inclined plane 403. The feeding space corresponds to the feeding inclined plane 401, and the feeding inclined plane 401 inclines towards the clamping plane 402, facilitating the smoother rolling of the metal products entering the feeding space 002 into the clamping space 001 and being fixed by the two clamping seats 5. The clamping plane 402 corresponds to the clamping space 001, and the discharging inclined plane 403 corresponds to the receiving frame 9 and inclines towards the receiving frame 9, facilitating the pushing out of the metal products that have completed the drilling operation from the clamping space 001 by the rotating dial rod 11 and falling onto the discharging inclined plane 403. Since the discharging inclined plane 403 inclines towards the receiving frame 9, it is convenient for the metal products that have completed the drilling operation to more smoothly fall into the receiving frame 9 along the discharging inclined plane 403.

[0036] The first drilling mechanism 2 includes a gantry 25 corresponding to the clamping space 001, a servo motor 26 installed on the gantry 25, a first lead screw 27 installed at the output end of the servo motor 26, a fixed seat 28 installed on the first lead screw 27 and moving on the gantry 25, a base 29 installed on the fixed seat 28, a first cylinder 30 installed on the base 29, a first mounting plate 31 installed at the output end of the first cylinder 30, a first motor 32 installed on the first mounting plate 31, and a first drill bit 33 installed at the output end of the first motor 32. The first drill bit 33 corresponds to the side surface of the metal product. The first lead screw 27 is rotationally connected to the frame. The gantry 25 is installed on the ground and connected to the workbench 1. The base 29 moves on the gantry 25. A slide rail is installed on the base 29, and the first mounting plate 31 moves on the base 29 through the slide rail. The first drill bit 33 corresponds to the clamping space 001, so that the first drill bit 33 can drill the side surface of the metal product fixed in the clamping space 001.

[0037] The first cylinder 30 on the base 29 works to drive the first mounting plate 31 to move on the base 29, causing the first motor 32 to move towards the metal product clamped and fixed in the clamping space 001. In cooperation with the operation of the first motor 32 to drive the first drill bit 33 to rotate, the metal product fixed in the clamping space 001 is drilled, thereby realizing the operation of the first drilling mechanism 2 to drill the side surface of the metal product fixed in the clamping space 001. In cooperation with the operation of the servo motor 26 to drive the first lead screw 27 to rotate, the fixed seat 28 is driven to move along the length direction of the metal product on the gantry 25, and then the base 29 connected to the fixed seat 28 is driven to move along the length direction of the metal product on the gantry 25, facilitating the first drill bit 33 on the base 29 to perform multi-point drilling on the side surface of a metal product, meeting the needs for different numbers of drill holes during processing and improving the practicality.

[0038] There are two second drilling mechanisms 3, and the two second drilling mechanisms 3 respectively drill the two end faces of the metal product. The second drilling mechanism 3 includes a second cylinder 34 installed on the gantry 25, a second mounting plate 35 connected to the output end of the second cylinder 34, a second motor 36 installed on the second mounting plate 35, and a second drill bit 37 installed on the output end of the second motor 36. The second drill bits 37 of the two second drilling mechanisms 3 respectively correspond to the two end faces of the metal product. The second drill bit 37 extends into the drilling channel 7 so that the second drill bit 37 in the drilling channel 7 drills the end face of the metal product fixed in the clamping space 001. The second mounting plate 35 slides on the gantry 25.

[0039] The second cylinder 34 works to drive the second mounting plate 35 to move, thereby driving the second motor 36 connected to the second mounting plate 35 and the second drill bit 37 installed on the output end of the second motor 36 to approach the corresponding clamping seat 5 and extend into the drilling channel 7. Cooperating with the operation of the second motor 36 to drive the second drill bit 37 to rotate, so that the second drill bit 37 extending into the drilling channel 7 drills the end face of the metal product, realizing that the two second drilling mechanisms 3 respectively drill the two end faces of the metal product, and thus cooperating with the first drilling mechanism 2 to realize drilling the side and end faces of the columnar metal product simultaneously, improving the drilling efficiency.

[0040] A support plate 38 corresponding to the second drilling mechanism 3 is installed on the gantry 25. The support plate 38 is connected to the workbench 1. The second cylinder 34 is installed on the support plate 38. The second mounting plate 35 slides on the support plate 38, which is convenient for strengthening the connection between the gantry 25 and the workbench 1 through the support plate 38, beneficial to improving the overall structural stability, and realizing the sliding of the second mounting plate 35 on the gantry 25 through the support plate 38.

[0041] A third motor 39, a second lead screw 40, an auxiliary rod 41, a support seat 42 and a connecting seat 43 are provided on the workbench 1. A first chamber 44 cooperating with the second lead screw 40 and a second chamber 441 cooperating with the auxiliary rod 41 are opened on the workbench 1. The two ends of the second lead screw 40 are respectively rotatably connected to the inner walls on both sides of the first chamber 44, and one end of the second lead screw 40 extends out of the first chamber 44 and is connected to the output end of the third motor 39. A guiding threaded sleeve 45 cooperating with the second lead screw 40 is provided in the first chamber 44. The guiding threaded sleeve 45 is movably connected to the second lead screw 40. The support seat 42 is installed on the guiding threaded sleeve 45 and is connected to the base 4. The support seat 42 slides in the first chamber 44. The auxiliary rod 41 is installed in the second chamber 441. The connecting seat 43 slides in the second chamber 441 and is slidably connected to the auxiliary rod 41. The connecting seat 43 is connected to the base 4 so that the third motor 39 drives the base 4 to move on the workbench 1 to make the next metal product to be processed fixed on the base 4 correspond to the first drill bit 33 and the second drill bit 37 for drilling.

[0042] The third motor 39 operates to drive the second lead screw 40 to rotate, thereby driving the support base 42 to move through the guiding threaded sleeve 45, and cooperating with the connecting seat 43 to slide on the auxiliary rod 41, so that the base 4 connected to both the support and the connecting seat 43 moves on the workbench 1, realizing the movement of the base 4 on the workbench 1. After the first drill bit 33 and the second drill bit complete drilling of a metal product, the first cylinder 30 drives the first motor 32 and the first drill bit 33 thereon away from the metal product, and cooperates with the operation of the third motor 39 to move the base 4 on the workbench 1 so that the adjacent metal product to be processed in the clamping space 001 to the metal product that has completed the drilling operation corresponds to the first drill bit 33 and the second drill bit 37, facilitating the first drill bit 33 and the second drill bit 37 to drill the next metal product to be processed, facilitating the drilling work of a plurality of metal products fixed in the clamping space 001, being conducive to the continuous progress of the drilling operation, and having high drilling efficiency.

The fixing frame 46 includes an activity space corresponding to the drilling channel 7, preventing the first hydraulic cylinder 6 from obstructing the movement of the second drill bit 37 when the second drill bit 37 moves closer to the corresponding drilling channel 7, so that the second drill bit 37 can smoothly extend into the drilling channel 7 to drill the end face of the metal product.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
