[0004] The following problems exist during the actual use of the above-mentioned device: during drilling, waste chips will fly everywhere. Since the above-mentioned device is not equipped with a shield, the waste chips will act on the workers and cause harm to the workers; and, multiple partitions are provided in the feed chute, which may cause the waste chips to be stuck between two adjacent partitions, affecting the recovery effect of the waste chips. Summary of the invention

[0007] The principles and advantages of this solution are: this solution places the workpiece on the processing table so that the workpiece is located between the two clamping blocks, and the workpiece is located between the two half frames; the spacing between the two clamping blocks is reduced by the adjustment mechanism, that is, the two clamping blocks are laterally approached, and the workpiece is clamped and positioned by the two clamping blocks; compared with the prior art, the clamping block squeezes the half frame and the movable block moves laterally, the movable block moves downward along the path of the inclined groove through the auxiliary block, and the movable block drives the half frame to move downward, so that the bottom of the half frame is against the top of the processing table, and at the same time the two half frames are against each other, that is, the two half frames form a complete frame, which surrounds the workpiece in the middle. Therefore, the waste chips generated during the drilling of the workpiece can be blocked by the two half frames to avoid harming the staff.

[0008] Furthermore, the adjustment mechanism includes a chamber opened inside the processing table, a bidirectional screw rotatably connected to the processing table, and a driving part for driving the bidirectional screw to rotate. The chamber is connected to the slide groove; the two clamping blocks are respectively threadedly connected to the two ends of the bidirectional screw.

[0009] Through the above arrangement, the driving part drives the bidirectional screw to rotate, so that the two clamping blocks are moved closer or farther away.

[0010] Furthermore, a groove is provided on the top of the processing table, and rotating shafts are rotatably connected on both sides of the groove. A cylinder is provided between the two rotating shafts, and a collecting hole is provided on the cylinder; the groove is communicated with the chamber, and a discharge port communicated with the chamber is provided on the processing table; and it also includes a power mechanism that drives the cylinder to rotate as the adjusting block moves.

[0011] Through the above arrangement, during the lateral movement of the clamping block, the clamping block drives the adjustment block to move lateraly through the lateral block, and drives the circular shaft to rotate 180 degrees through the power mechanism, so that the collecting hole faces upward to collect waste chips generated during drilling.

[0012] During the reverse lateral movement of the adjusting block, the power mechanism drives the circular shaft to rotate 180 degrees in the reverse direction, so that the rotating shaft drives the cylinder to rotate in the reverse direction and reset, and the collecting hole faces downward, so that the waste chips in the cylinder can automatically fall downward and finally be discharged from the discharge port.

[0013] Furthermore, the power mechanism includes a power unit located on both sides of the chamber, the power unit includes a power shaft rotatably connected to the chamber, and a power block fixed to the adjusting block.

[0015] During the reverse lateral movement of the adjusting block, the adjusting block drives the power block to move in the reverse lateral direction. The power block drives the cylindrical cam to rotate in the reverse direction through the curved groove. The circular shaft drives the rotating shaft to rotate in the reverse direction through the belt, so that the rotating shaft drives the cylinder to rotate in the reverse direction and reset.

[0019] Through the above arrangement, during the rotation of the cam body, the first wedge block is driven to move laterally through the linkage mechanism, that is, the two first wedge blocks move away from each other; during the lateral movement of the first wedge block, the first wedge block squeezes the second wedge block to move downward, and the spring is stretched; the first wedge block continues to move laterally, and the second wedge block is vertically opposite to the stop groove, so that the second wedge block slides into the stop groove under the action of the spring, thereby realizing the positioning of the first wedge block, that is, the movement of the clamping block is avoided through the linkage mechanism, cam body, round shaft, cylindrical cam, power block, adjustment block, and transverse block, thereby enhancing the positioning effect of the clamping block, and then enhancing the positioning effect of the workpiece.

[0020] After completing the drilling process of the workpiece, the second wedge block is driven to move downward, so that the second wedge block moves out of the stop groove, allowing the first wedge block to be in a state of transverse movement, so that the side block, cam body, round shaft, cylindrical cam, power block, adjustment block, transverse block and clamping block can move, that is, the clamping block can return to its initial position for the next drilling process.

[0021] Furthermore, the width of the cam body decreases gradually from top to bottom; the linkage mechanism comprises an annular groove provided on the cam body, a side block slidably connected to the annular groove, and the side block is fixedly connected to the first wedge block.

[0038] The specific implementation process is as follows:

[0039] When in use, the workpiece 70 is placed on the processing table 20 so that the workpiece 70 is located directly above the groove 40 , and the workpiece 70 is located between the two clamping blocks 23 , and the workpiece 70 is also located between the two half frames 26 .

[0040] The second motor 32 is started, and the output shaft of the second motor 32 drives the bidirectional screw 31 to rotate, so that the two clamping blocks 23 are close to each other. When the two clamping blocks 23 are respectively against the two sides of the workpiece 70, the second motor 32 is turned off, that is, the workpiece 70 is clamped and positioned by the two clamping blocks 23.

[0041] During the period when the two clamping blocks 23 approach each other, the clamping block 23 moves laterally, and the clamping block 23 drives the adjusting block 28 to move laterally as well, so that the adjusting block 28 moves away from the movable block 25, that is, the supporting effect of the adjusting block 28 on the movable block 25 and the half frame 26 disappears, and the clamping block 23 squeezes the half frame 26 and the movable block 25 to move laterally, that is, the two half frames 26 approach each other, and the two movable blocks 25 also approach each other; during the period when the movable block 25 moves laterally, the movable block 25 moves downward along the path of the inclined groove 24 through the auxiliary block, and the movable block 25 drives the half frame 26 to move downward, so that the clamping block 23 moves vertically relatively in the first strip groove 261, and the transverse block 27 moves vertically relatively in the second strip groove 251; during the period when the half frame 26 moves downward, when the workpiece 70 is clamped and positioned, the bottom of the half frame 26 abuts against the top of the processing table 20, and at the same time, the two half frames 26 abut against each other, that is, the two half frames 26 form a complete frame, surrounding the workpiece 70 in the middle.

[0042] During the lateral movement of the adjustment block 28, the adjustment block 28 drives the power block 51 to move horizontally, the power block 51 drives the cylindrical cam 52 to rotate through the curved groove 53, the cylindrical cam 52 drives the circular shaft to rotate, and the circular shaft drives the rotating shaft 41 to rotate through the belt 54. When the workpiece 70 is positioned, the rotating shaft 41 drives the cylinder 42 to rotate 180 degrees, so that the collecting hole 43 faces upward, which is used to collect waste chips generated by drilling.

[0043] During the rotation of the circular shaft, the circular shaft drives the cam body 55 to rotate. When the workpiece 70 is positioned, the raised portion of the cam body 55 abuts against the cylinder 42, thereby limiting and supporting the cylinder 42 to prevent the cylinder 42 from rotating and ensuring that waste chips can be collected into the cylinder 42 through the collecting hole 43.

[0044] During the rotation of the cam body 55, the cam body 55 drives the first wedge block 62 to move laterally through the annular groove 67 and the side block 68, that is, the two first wedge blocks 62 move away from each other; during the lateral movement of the first wedge block 62, the first wedge block 62 squeezes the second wedge block 64 to move downward, and the spring 65 is stretched; the first wedge block 62 continues to move laterally, so that the second wedge block 64 is against the side wall of the first wedge block 62. When positioning the workpiece 70, the second wedge block 64 is vertically opposite to the stop groove 63, so that the second wedge block 64 slides into the stop groove 63 under the action of the spring 65, thereby realizing the positioning of the first wedge block 62 and avoiding the lateral movement of the first wedge block 62 and the side block 68, that is, the movement of the clamping block 23 is avoided by the cam body 55, the round shaft, the cylindrical cam 52, the power block 51, the adjustment block 28, and the transverse block 27, thereby enhancing the positioning effect of the clamping block 23, and then enhancing the positioning effect of the workpiece 70.

[0045] After completing the positioning of the workpiece 70, start the first hydraulic cylinder 14, the output shaft of the first hydraulic cylinder 14 drives the top plate 12 to move horizontally, the top plate 12 drives the drill bit 17 to move to just above the workpiece 70, and the first hydraulic cylinder 14 is closed; start the first motor 16, the output shaft of the first motor 16 drives the drill bit 17 to rotate; start the second hydraulic cylinder 15, the output shaft of the second hydraulic cylinder 15 drives the lifting block 13 to move downward, the lifting block 13 drives the drill bit 17 to move downward, and the drill bit 17 is used to drill the workpiece 70; during the drilling process of the workpiece 70, the waste chips generated are collected into the cylinder 42 through the groove 40 and the collecting hole 43, and a small part of the waste chips are splashed. The waste chips can be blocked by the two half frames 26 to avoid harming the staff.

[0046] After the drilling process of the workpiece 70 is completed, the pedal 66 is stepped on and moved downward, so that the second wedge block 64 moves out of the stop groove 63, and the first wedge block 62 is in a state of being able to move laterally.

[0047] Start the second motor 32, and the output shaft of the second motor 32 drives the bidirectional screw 31 to rotate in the opposite direction, so that the two clamping blocks 23 move away from each other, and the clamping block 23 drives the adjusting block 28 to move in the opposite direction through the transverse block 27, and the adjusting block 28 drives the cylindrical cam 52 to rotate in the opposite direction through the power block 51, and the cylindrical cam 52 drives the circular shaft to rotate in the opposite direction, and the circular shaft drives the cam body 55 to rotate in the opposite direction, and the cam body 55 drives the first wedge block 62 to move in the opposite direction through the annular groove 67 and the side block 68, so that the two first wedge blocks 62 are close to each other, and when the first wedge block 62 moves in the opposite direction to the initial position, the second motor 32 is turned off.

[0048] During the reverse rotation of the cylindrical cam 52, the raised portion of the cylindrical cam 52 is away from the cylinder 42, allowing the cylinder 42 to be rotatable; during the reverse rotation of the cylindrical cam 52, the circular shaft also rotates in the reverse direction, and the circular shaft drives the rotating shaft 41 to rotate in the reverse direction through the belt 54, and the rotating shaft 41 drives the cylinder 42 to rotate in the reverse direction, so that the collecting hole 43 faces downward, and the waste chips in the cylinder 42 fall downward, so that the waste chips are discharged through the discharge port 44.
