Description

Technical Field

[0001] The present invention relates specifically to the technical field of double-end drilling, in particular to a double-end drilling device and process. Background Art

[0002] The double-head drilling device is a device that can perform drilling processing at two locations on the workpiece at the same time; the double-head drilling device can achieve simultaneous processing and effectively improve production efficiency; At present, the traditional drilling device can only process one workpiece during the processing, which has low work efficiency. In addition, in the traditional machining, the drilling position of the workpiece is directly processed by the drill bit. After long-term use, when the chip cutting edge of the drill bit is seriously worn, the operator cannot stop it in time. As a result, the processing accuracy and processing size of the drill hole cannot be guaranteed during drilling, and even the drill bit may break. At present, the conventional drilling device does not have a device for positioning the drilling position. Thus, when the drill bit contacts the workpiece, a large stress is generated between the workpiece and the drill hole, which may cause the direction and position of the drilling hole to deviate, resulting in inaccurate drilling position or the drill bit to deviate during the drilling process, causing the drilling hole to deviate, and the drilling processing quality cannot be effectively guaranteed. After searching; Chinese patent publication number CN202321998627.1 discloses a double-head drilling device; it includes a frame, drilling mechanisms are provided on both sides of the frame, and also includes a clamping mechanism, the clamping mechanism is located between the drilling mechanisms on both sides, the clamping mechanism includes a fixing component for clamping and fixing the parts, and a positioning component for positioning the parts after fixing; the positioning component includes two groups of threaded rods rotatably arranged on both sides of the frame, and each group is provided with two threaded rods, and the two threaded rods are symmetrically arranged front to back, two first motors are provided above the frame, and the two first motors are symmetrically arranged on both sides, the threads arranged on the upper and lower sides of the threaded rods are in opposite directions, an upper pressing plate is provided on the upper side of the threaded rod, and a lower pressing plate is provided on the lower side of the threaded rod, the upper pressing plate and the lower pressing plate are both threadedly connected to the threaded rod, the lower pressing plate and the upper pressing plate are both slidably connected to the frame, and two guide assemblies are provided between the upper pressing plate and the lower pressing plate, and the two guide assemblies are symmetrically arranged front to back; In the above patent, when drilling a workpiece, the workpiece is placed on the lower pressure plate, and the first electric push rod pushes the first top block to clamp and fix the front end of the workpiece, and the second electric push rods on both sides push the second top block to clamp and fix the two sides of the workpiece, and then the drill bit is driven to rotate by the second motor, and the hydraulic cylinder is used to perform telescopic adjustment. In this way, when the drill bit contacts the surface of the workpiece (especially a circular or curved surface), the stress generated between the drill bit and the workpiece when the drill bit rotates at high speed will cause the position of the drill bit to shift, and the accuracy of the processing position cannot be effectively guaranteed. Moreover, the structure in the above patent cannot realize the positioning processing of the drilling position, which will cause the processed drilled holes to not meet the requirements and result in the generation of waste. Summary of the Invention

When the placement plate rotates, the lifting rod drives the punching positioning assembly to move upward to avoid contact between the drill bit and the workpiece. After the drilling positioning of the workpiece is completed, the placement plate is rotated to realize the transfer of the workpiece to the position of the double-head drilling assembly.

[0020] The shifting post 24 is engaged with the worm 62 in the driving assembly 6; the driving assembly 6 further includes a support frame 63; both ends of the worm 62 are movably mounted on the support frame 63; One end of the worm 62 is fitted with a driven wheel 64, and the end of the worm 62 is fixedly connected to an intermittent push block 66; the driven wheel 64 is connected to the active wheel on the output shaft of the fourth drive motor 60 through a connecting belt 65; the support frame 63 fitted with the worm 62 and the fourth drive motor 60 are both fixedly mounted on the crossbeam at the bottom of the workbench 1 By adopting the above technical solution, when in use, the workpiece to be drilled is placed in the positioning structure 21 at the edge of the placement plate 20, and the position of the workpiece is determined by the positioning structure 21, and the workpiece is clamped and fixed at the same time. The placement plate 20 is fixedly installed with the rotating disk 23 through the rotating shaft 22, and a plurality of shifting pins 24 are fixedly installed on the edge of the rotating disk 23. Through the cooperation of the shifting pins 24 and the worm 62, the rotating disk 23 effectively drives the placement plate 20 to rotate, and the workpiece in the positioning structure 21 is sequentially passed through the punching positioning component 4 and the double-head drilling component 5 to realize the drilling processing of the workpiece; See also Figure 3 、 4 , 5, 10; further; the worm 62 is away from the driven wheel 64 at one end thereof with a cam 61 mounted thereon; the cam 61 is connected in conjunction with the linkage assembly 3; The linkage assembly 3 includes a connecting rod 31; the connecting rod 31 is arranged horizontally; the end of the connecting rod 31 close to the cam 61 is mounted with a pressure wheel 33 via a plug post; the end of the connecting rod 31 away from the pressure wheel 33 is movably mounted with the lifting rod 30 via a pin; the end of the lifting rod 30 away from the connecting rod 31 extends through the workbench 1 to the top of the placement plate 20; By adopting the above technical solution, while the fourth driving motor 60 drives the worm 62 to cooperate with the shift column 24 to realize that the rotating disk 23 drives the placement plate 20 to rotate, the cam 61 installed at one end of the worm 62 away from the driven rotating wheel 64 effectively cooperates with the pressure wheel 33. Through the cooperation of the cam 61 and the pressure wheel 33, the connecting rod 31 is effectively realized through the support block 32 to drive the lifting rod 30 to slide up and down. When the small end of the cam 61 cooperates with the pressure wheel 33, the lifting rod 30 drives the punching positioning assembly 4 to move downward, thereby determining and pre-processing the drilling of the workpiece. As the worm 62 rotates, the cam 61 rotates at the same time. When the placement plate 20 rotates, the large end of the cam 61 contacts the pressure wheel 33, thereby pressing down the pressure wheel 33. The connecting rod 31 is lifted up at one end away from the pressure wheel 33 through the support block 32, thereby separating the drill bit in the punching positioning assembly 4 from the workpiece. See also Figure 1-6 In this embodiment, the connecting rod 31 is close to the side wall of the lifting rod 30 and is mounted on the support block 32 through a pin; the bottom of the support block 32 is fixedly mounted on the beam at the bottom of the workbench 1; A drilling and positioning assembly 4 is fixedly mounted on the top of the lifting rod 30; the drilling and positioning assembly 4 includes a fixing rod 40; a support frame 42 is fixedly mounted on the fixing rod 40; a first motor 41 is fixedly mounted on the top of the support frame 42; the output shaft of the first motor 41 is cooperatively connected to a fixing clamp of a drilling and positioning drill bit; By adopting the above technical solution, when the two workpieces are simultaneously transferred to the position of the double-head drilling assembly 5 by the placement plate 20, the drill bits clamped by the two drill bit holders 50 are used to realize simultaneous drilling of the two workpieces by the second drive motor 57. The drill bits in the double-head drilling assembly 5 continue to process the holes processed in the drilling and positioning assembly 4, so that the holes drilled on the workpieces meet the production requirements. The third drive motor 512 drives the screw rod 59 to rotate, so that the screw rod 59 drives the support frame 511 to adjust up and down, thereby realizing that the two drill bit holders 50 drive the drill bits to move up and down through the support frame 511, thereby realizing drilling of the workpieces. See also Figure 1-4 ; The top of the workbench 1 is also equipped with a double-headed drilling assembly 5; the double-headed drilling assembly 5 includes two drill clamps 50; the tops of the two drill clamps 50 are equipped with a first pulley 51; the two first pulleys 51 are connected to the second pulley 53 through a first belt 52; the second pulley 53 is integrally provided with two; the second pulley 53 is also connected to the third pulley 54 through a second belt 55; the third pulley 54 is fixedly mounted on the output shaft of the second drive motor 57; the second drive motor 57 is fixedly mounted on the bottom of the support frame 511; The support frame 511 is mounted on the drill bit holder 50 via two fixing frames 510.

The top of the guide rod 58 passes through the support frame 511. By adopting the above technical solution, during the drilling process, the third pulley 54 is driven by the second drive motor 57 to drive the second pulley 53 to rotate through the second belt 55. At the same time, the second pulley 53 is connected to the two first pulleys 51 through the second pulley 53. The two first pulleys 51 are respectively connected to the two drill bit clamps 50, thereby effectively realizing that the second drive motor 57 drives the drill bits on the two drill bit clamps 50 to simultaneously realize drilling processing on two workpieces, thereby greatly improving work efficiency.

[0021] The working principle of the present invention is as follows: when in use, the workpiece to be drilled is placed in the positioning structure 21 at the edge of the placement plate 20, the position of the workpiece is determined by the positioning structure 21, and the workpiece is clamped and fixed at the same time, the placement plate 20 is fixedly installed with the rotating disk 23 through the rotating shaft 22, and a plurality of shifting pins 24 are fixedly installed on the edge of the rotating disk 23. Through the cooperation of the shifting pins 24 and the worm 62, the rotating disk 23 effectively drives the placement plate 20 to move, and the workpiece in the positioning structure 21 is sequentially passed through the punching positioning component 4 and the double-head drilling component 5 to realize the drilling processing of the workpiece; When the fourth driving motor 60 drives the worm 62 to cooperate with the shift post 24 to realize that the rotating disk 23 drives the placing plate 20 to rotate, the cam 61 installed at one end of the worm 62 away from the driven rotating wheel 64 effectively cooperates with the pressure wheel 33, and the cooperation of the cam 61 and the pressure wheel 33 effectively realizes that the connecting rod 31 drives the lifting rod 30 to slide up and down through the support block 32. When the small end of the cam 61 cooperates with the pressure wheel 33, the lifting rod 30 drives the punching positioning assembly 4 to move downward, realizing the determination and pre-processing of the workpiece drilling. With the rotation of the worm 62, the cam 61 rotates at the same time. When the placing plate 20 rotates, the large end of the cam 61 contacts the pressure wheel 33, realizing the downward pressure of the pressure wheel 33, and the connecting rod 31 is lifted up by the support block 32 away from the pressure wheel 33, realizing the separation of the drill bit in the punching positioning assembly 4 from the workpiece; In this process, the positions of the shift pins 24 and the positioning structure 21 are set to correspond one to one. At this time, there is a wide spacing between the shift pins 24. When the worm 62 drives the shift pins 24 to rotate, due to the short worm 62, only one shift pin 24 can be driven to move. When the spacing is large, the subsequent shift pins 24 cannot continue to transmit at the position of the worm 62. At this time, the intermittent push block 66 at the end of the worm 62 is used to push the shift pin 24 at this position to continue to move an end distance, so that the subsequent shift pin 24 can continue to rotate. At the same time, there will be an intermittent time every time the top positioning structure 21 rotates, which facilitates the drilling process. When the two workpieces are simultaneously transferred to the position of the double-head drilling assembly 5 by the placement plate 20, the drill bits clamped by the two drill clamps 50 are used to perform drilling processing on the two workpieces at the same time through the second drive motor 57. The drill bits in the double-head drilling assembly 5 continue to process the holes processed in the drilling and positioning assembly 4, so that the holes drilled on the workpieces meet the production requirements. The third drive motor 512 drives the screw rod 59 to rotate, so that the screw rod 59 drives the support frame 511 to adjust up and down, thereby enabling the two drill clamps 50 to drive the drill bits to move up and down through the support frame 511 to achieve drilling processing on the workpieces; During the drilling process, the third pulley 54 is driven by the second drive motor 57 to rotate the second pulley 53 through the second belt 55. At the same time, the second pulley 53 is connected to the two first pulleys 51 through the second pulley 53. The two first pulleys 51 are respectively connected to the two drill bit clamps 50, thereby effectively realizing the second drive motor 57 driving the drill bits on the two drill bit clamps 50 to simultaneously realize the drilling processing of the two workpieces, greatly improving work efficiency.
