[0032] The following is for reference. Figures 1 to 8 This invention describes a double-sided punching machine according to an embodiment of the present invention.

[0033] The double-sided punching machine of this utility model embodiment is described in reference to... Figure 1 It includes a base frame 001 and a clamping device 400 and a drilling device disposed on the base frame 001.

[0034] Reference Figure 3 The clamping device 400 includes two clamping arms 420 and a first driver for driving the two clamping arms 420 to move closer to or further away from each other. Both clamping arms 420 are horizontally extending strips and are spaced apart. The first driver can be a pneumatic gripper 410. The main body of the pneumatic gripper 410 is fixedly mounted on the base frame 001. The two gripping fingers of the pneumatic gripper 410 are connected one-to-one to the ends of the two clamping arms 420, which can drive the two clamping arms 420 to move closer to or further away from each other. Each clamping arm 420 is provided with a clearance through hole 430. The clearance through hole 430 is located at the end of the clamping arm 420 away from the pneumatic gripper 410. The clearance through hole 430 extends forward and backward and is coaxial. A clamping space is provided between the two clearance through holes 430.

[0035] The drilling device includes two drilling mechanisms 100, with two clamping arms 420 disposed between the two drilling mechanisms 100. The two drilling mechanisms 100 are arranged in a front-to-back mirror symmetrical configuration or a centrally symmetrical configuration with the clamping space as the center of symmetry. Each drilling mechanism 100 includes a drill bit 150, a second driver 130, and a third driver 110. The drill bit 150 extends front-to-back, and two clearance through holes 430 are coaxial with both drill bits 150. The second driver 130 is used to drive the drill bit 150 to rotate, and the third driver 110 is used to drive the drill bit 150 to move along the axial direction of the drill bit 150. Alternatively, the third driver 110 can be configured to drive the second driver 130 to move back and forth, and the drill bit 150 can be disposed on the second driver 130, thus achieving simultaneous rotation and movement of the drill bit 150. Or, the second driver 130 can be configured to drive the third driver 110 to rotate, and the drill bit 150 can be disposed on the third driver 110, also achieving simultaneous rotation and movement of the drill bit 150.

[0036] In use, decorative jade stones, beads, and other objects to be processed can be moved into the clamping space. Then, the first driver is controlled to clamp the object, and the two drilling mechanisms 100 are controlled to allow the two drill bits 150 to pass through the corresponding clearance holes 430 and drill holes from both sides of the object. This invention can drill holes from both sides of the object simultaneously, resulting in faster processing speeds and improved production efficiency. By setting the clearance holes 430, the clamping direction of the clamping device 400 is aligned with the feed direction of the drill bits 150, making the clamping device 400 more stable in holding the object during drilling.

[0037] In some embodiments of this utility model, the double-sided punching machine also includes a collection trough 500, which is located below the clamping space. This allows the clamping device 400 to directly release the processed object after drilling is completed, and the processed object falls into the collection trough 500 for easy recycling.

[0038] In some embodiments of this utility model, each clamping arm 420 has a positioning groove on the side facing the clamping space. A clearance through hole 430 is located in the center of the positioning groove. For the clamping arm 420 located on the front side, its positioning groove is located on the rear side of the clamping arm 420; for the clamping arm 420 located on the rear side, its positioning groove is located on the front side of the clamping arm 420. This makes the clamping of the workpiece more stable. The clamping arm 420 is provided with a positioning element 440, and a positioning groove is located on the positioning element 440. The positioning element 440 is an independent component and is fixedly installed on the clamping arm 420. Thus, the clamping arm 420 can be made of a high-strength material such as metal, while the positioning element 440 can be made of a low-hardness material such as plastic to prevent damage to the surface of the jade. Of course, in other embodiments of this utility model, the clamping arm 420 and the positioning element 440 can also be set as an integral component, which simplifies the structure and makes the positioning more accurate.

[0039] In some embodiments of this utility model, the double-sided punching machine further includes a feeding device, which includes a material container and a conveying mechanism 300 for conveying the material in the material container to the clamping space. In use, the operator can place the workpiece to be processed in the material container, and the conveying mechanism 300 will transport the workpiece to the clamping space, avoiding the problem of easy injury caused by the operator directly placing the workpiece in the clamping space, thus improving safety.

[0040] In some embodiments of this utility model, reference is made to Figure 2The conveying mechanism 300 includes a crossbeam 310, a translation seat 330 slidably disposed on the crossbeam 310, and a fourth driver 320 for driving the translation seat 330 to move along the crossbeam 310. The crossbeam 310 is disposed between the material container and the clamping device 400. The translation seat 330 is provided with a vacuum suction cup 350 and a fifth driver 340 for driving the vacuum suction cup 350 to rise and fall. In use, the vacuum suction cup 350 picks up the workpiece to be processed from the material container. The fourth driver 320 and the fifth driver 340 are controlled to move the vacuum suction cup 350 to the upper side of the clamping space. Then, the clamping device 400 clamps the workpiece, and the vacuum suction cup 350 releases it, thus conveying the workpiece from the material container to the clamping space. The crossbeam 310 is fixedly mounted on the base frame 001. The crossbeam 310 is horizontally positioned, and a horizontally positioned guide rail slider mechanism connects the crossbeam 310 and the translation seat 330 to achieve a sliding connection. The fourth driver 320 can be a linear motor, a rotary motor driving a screw and nut pair mechanism, or other suitable linear drivers, capable of driving the translation seat 330 to move along the crossbeam 310. The fifth driver 340 can be a vertically positioned lifting cylinder, with its main body fixedly mounted. In the translation seat 330, the movable part of the lifting cylinder is connected to the vacuum suction cup 350. The movement of the vacuum suction cup 350 has a first state. In the first state, the vacuum suction cup 350 is located on the upper side of the clamping space and the suction area of ​​the vacuum suction cup 350 coincides with the clamping space. The vacuum suction cup 350 is connected to a suction pipe to provide a vacuum. The suction pipe can be equipped with a solenoid valve and a flow sensor. When it is necessary to pick up the workpiece, the solenoid valve is controlled to open the suction pipe. Then, the flow rate detected by the flow sensor can be used to determine whether the vacuum suction cup 350 has picked up the workpiece. When the flow sensor detects that the flow rate in the suction pipe is small, it indicates that the workpiece is blocking the vacuum suction cup 350, that is, the workpiece has been successfully picked up. When the flow sensor detects that the flow rate in the suction pipe is large, it means that the workpiece has not been picked up. Similarly, the flow sensor is replaced by a pressure sensor 121. Of course, in other embodiments of this utility model, the conveying mechanism 300 may also be a robotic arm or other suitable device that can convey the workpiece to be processed from the material container to the clamping space.

[0041] In some embodiments of this utility model, the clamping device 400 and the drilling device are collectively referred to as a drilling unit. Multiple drilling units are arranged sequentially along the extension direction of the crossbeam 310. When one drilling unit drills a hole in one piece of jade, the conveying mechanism 300 can transport another piece of jade to another drilling unit. Multiple drilling units can work simultaneously, which improves production efficiency. Furthermore, multiple drilling units share the same conveying mechanism 300, simplifying the equipment structure. Operators only need to place the workpiece to be processed into the same material container for multiple drilling units to operate, making operation convenient. The number of drilling units can be two, three, or more, such as... Figure 6 As shown.

[0042] In some embodiments of this utility model, reference is made to Figure 8 The material container is a tray 280, which is located below the vacuum suction cup 350. The upper surface of the tray 280 has multiple receiving slots 281. The conveying mechanism 300 also includes a sixth driver 290 for driving the tray 280 to translate along a first direction, which is different from the extension direction of the crossbeam 310. The multiple receiving slots 281 are arranged in a rectangular array, with the first direction being the front-to-back direction. The sixth driver 290 is located on the base frame 001. The sixth driver 290 can be a linear motor, a rotary motor driving a screw and nut assembly, or other suitable linear drivers, as long as it can drive the tray 280 to move back and forth. The fourth driver 320 can adjust the lateral position of the vacuum suction cup 350, and the sixth driver 290 can adjust the front and rear position of the tray 280, so that the suction cup can move relative to the tray 280 above each receiving slot 281, thereby enabling the conveying mechanism 300 to convey multiple jade stones one by one; in use, the staff can place a batch of jade stones on the tray 280 for the double-sided drilling machine to run continuously.

[0043] In some embodiments of this utility model, the material container is a hopper 210, and the bottom of the hopper 210 is provided with a discharge trough. The end of the discharge trough away from the hopper 210 is located within the movement range of the vacuum suction cup 350. In use, workers can place batches of jade stones into the hopper 210 for continuous operation of the double-sided drilling machine. The width of the discharge trough is adapted to the size of the jade stones to be processed, allowing the jade stones to be arranged sequentially within the trough. The jade stones in the hopper 210 can then be moved sequentially to the end of the discharge trough, where the vacuum suction cup 350 can pick up the jade stones one by one for transport.

[0044] In some embodiments of this utility model, reference is made to Figure 7The discharge trough has a first trough section 220 and a second trough section 260. The first trough section 220 is located between the hopper 210 and the second trough section 260. A linear vibrating feeder 230 is connected to the bottom of the first trough section 220. The bottom of the hopper 210 has a strip-shaped discharge section. The first trough section 220 is located inside the discharge section. The side wall of the hopper 210 has a discharge port adapted to the first trough section 220. One end of the first trough section 220 near the second trough section 260 extends from the discharge port to the outside of the hopper 210. The linear vibrating feeder 230 is connected between the base frame 001 and the first trough section 220. The conveying direction of the linear vibrating feeder 230 is towards the second trough section 260. The second trough section 260 extends from the end of the first trough section 220 along the first trough section 260. The first groove segment 220 extends downward at an angle. The second groove segment 260 can be located in the middle of the crossbeam 310 or at its end. The second groove segment 260 is fixedly mounted on the base frame 001. The vacuum suction cup 350 has a second state of movement. In the second state, the vacuum suction cup 350 is located above the lower end of the second groove segment 260, and the suction area of ​​the vacuum suction cup 350 coincides with the lower end of the second groove segment 260, allowing the vacuum suction cup 350 to pick up the jade located at the lower end of the second groove segment 260. By setting the linear vibrating feeder 230, even if the jade to be processed is not spherical, the jade can be orderly conveyed along the first groove segment 220 to the second groove segment 260.

[0045] In some embodiments of this utility model, the outer wall of the hopper 210 is provided with a baffle 240, the baffle 240 is provided with a vertically extending waist-shaped groove, the hopper 210 is provided with an adjusting bolt, the adjusting bolt passes through the waist-shaped groove and is threadedly connected to the hopper 210, and the lower end of the baffle 240 is located in the first groove section 220; thus, loosening the adjusting bolt can adjust the vertical position of the baffle 240, thereby covering part of the discharge port, so that the height of the channel defined between the lower end of the baffle 240 and the first groove section 220 can only allow one jade stone to pass through; by setting the baffle 240 and the adjusting bolt, this embodiment can adapt to jade stones of different sizes, so that the jade stones can be transported in an orderly manner along the first groove section 220.

[0046] In some embodiments of this utility model, a proximity sensor 250 is provided on the side of the first groove section 220. The sensing area of ​​the proximity sensor 250 is located at the end of the first groove section 220 near the second groove section 260. During normal use, the proximity sensor 250 detects jade in the sensing area. When the proximity sensor 250 does not detect jade, it indicates that the jade in the hopper 210 has been exhausted, reminding the staff to replenish the jade in the hopper 210. At this time, there is still a certain amount of jade in the second groove section 260. Before the staff replenishes the jade in the hopper 210, the jade in the second groove section 260 can allow the double-sided drilling machine to continue running for a period of time, which helps to shorten the downtime.

[0047] In some embodiments of this utility model, the drilling mechanism 100 includes a movable base 120, a third driver 110, the movable base 120, a second driver 130, and a drill bit 150 connected in sequence. Taking the drilling mechanism 100 located at the front of the clamping space as an example, the bottom of the movable base 120 is provided with a guide rail slider mechanism to slide along the front-back direction on the base frame 001. The third driver 110 includes a screw, a ball nut sleeved on the outside of the screw, and a third motor for driving the screw to rotate. The ball nut is connected to the movable base 120, and the third motor is located in front of the movable base 120. The second driver 130 is a motor and is located on the upper side of the movable base 120. The output shaft of the second driver 130 is provided with a tool holder 140, which is located on the rear side of the second driver 130. The drill bit 150 is located on the tool holder 140. This structure is simple and easy to set up.

[0048] In some embodiments of this utility model, reference is made to Figure 4 A pressure sensor 121 is connected between the movable seat 120 and the third driver 110. Taking the drilling mechanism 100 located at the front of the clamping space as an example, the ball nut has a connecting flange, which is located at the front of the movable seat 120. The pressure sensor 121 is located between the connecting flange and the movable seat 120. One end of the pressure sensor 121 is connected to the movable seat 120, and the connecting flange is located at the front of the other end of the pressure sensor 121. The connecting flange has multiple connecting bolts, which pass through the connecting flange from front to back and are threaded onto the movable seat 120, such that the front of the connecting flange abuts against the bolt head of the connecting bolt, and the rear of the connecting flange abuts against the pressure sensor 121. Of course, in other embodiments of this utility model, refer to Figure 5 The left end of the pressure sensor 121 is mounted to the movable base 120 via a vertically arranged hinge bolt 122, making the pressure sensor 121 hinged to the movable base 120. The right end of the pressure sensor 121 abuts against the rear side of the connecting flange, and the sensing contact of the pressure sensor 121 is located on the rear side of the pressure sensor 121 and abuts against the movable base 120. In this way, when the third actuator 110 drives the movable base 120 away from the clamping space, the second actuator 130 and the drill bit 150 can normally move away from the clamping space. When the third actuator 110 drives the movable base 120 closer to the clamping space for drilling, if the drill bit 150 is operating normally, the pressure sensor 121 will detect an increase in pressure. If the drill bit 150 breaks, the pressure sensor 121 will not detect an increase in pressure. Therefore, the pressure signal detected by the pressure sensor 121 can determine whether the drill bit 150 has broken, which is convenient for the operator to replace the drill bit 150 in time.
