DETAILED DESCRIPTION

[0020] Example 1

[0021] like Figures 1-4 As shown, a modular puncher proposed in this embodiment includes a power head assembly and a die set.

[0022] The die assembly includes a connecting assembly installed on the power head assembly, a screw 15 connected to the output end of the power head assembly, a screw sleeve 19 with a clamping portion at the end and a limit platform portion on the outer periphery, a punch fixing block 25 for the clamping portion to be clamped, and a punching assembly connected to the connecting assembly. The screw sleeve 19 is threadedly connected to the screw 15. The screw sleeve 19 is slidably set on the connecting assembly through the limit platform portion. The punch fixing block 25 has a penetrating installation channel, and the installation channel faces the clamping portion of the screw sleeve 19. The punch fixing block 25 has a "convex"-shaped clamping channel, and the clamping portion is clamped in the clamping channel. One end of the clamping channel is open, so that the screw sleeve 19 can pass through the opening and the clamping portion can be clamped on the inner side of the clamping channel.

[0023] The punching assembly includes a punch 21, a replaceable first die 26, and a first fixing frame 23 connected to the connecting block 22 by a bolt 24 and having a first clamping space and a notch. The first die 26 has a U-shaped clamping channel. The first die 26 has a first socket 261 and a second socket 262 that are coaxially connected along the width direction of the clamping channel. The first socket 261 is a positioning hole, and the second socket 262 is a punching hole. The first socket 261 is coaxially distributed with the installation channel. The punch 21 is installed in the installation channel and faces the first socket 261. When the workpiece to be punched is placed inside the clamping channel, the screw sleeve 19 is driven forward by the power head assembly. The screw sleeve 19 drives the punch fixing block 25 and the punch 21 forward. The head of the punch 21 penetrates the workpiece and moves into the second socket 262 to complete the punching process of the workpiece. The first fixing frame 23 is threadedly connected with a first bolt that is tightened on the first die 26, which is used to fix the position of the first die 26. The first die 26 slides up and down and is clamped inside the clamping space. The punch fixing block 25 slides back and forth and is clamped inside the clamping space. The first fixing frame 23 has a through hole 231 coaxially distributed with the second insertion hole 262 (punching hole). The waste punched off the workpiece by the punch 21 enters the through hole 231 from the second insertion hole 262 and is finally discharged from the through hole 231. The size of the through hole 231 is larger than the size of the second insertion hole 262.

[0024] The power drill assembly includes a shift button 1, a right housing 2, a gearbox 3, a brushless motor 4, a left housing 5, a reversing button 6, a stepless speed control switch 7, a controller 8, a battery pack 9, a transparent light cover 10, and a keypad 11. The shift button 1, right housing 2, gearbox 3, brushless motor 4, left housing 5, reversing button 6, stepless speed control switch 7, and battery pack 9 all employ similar structures to those found in existing pistol drills. The right and left housings 2 and 5 are detachably connected, while the gearbox 3 and brushless motor 4 are mounted within the housings. The shift button 1, reversing button 6, stepless speed control switch 7, controller 8, and battery pack 9 are also mounted on the housings. The keypad 11 is mounted on both the right and left housings 2 and 5 and is electrically connected to the controller 8 for switching the tool to manual gear. A transparent light cover 10 covers the display area in the center of the keypad 11. The output end of the brushless motor 4 is connected to the input end of the gear box 3, and the battery pack 9 supplies power to the brushless motor 4. The battery pack 9 is detachable and can be replaced with another fully charged battery pack 9 when the power is used up.

[0025] The connecting assembly includes a hexagonal fixing sleeve 12 secured to the gearbox 3, a fixing sleeve 13 threadedly connected to the gearbox 3, an outer sleeve 14 threadedly connected at one end to the hexagonal fixing sleeve 12, a connecting block 22 threadedly connected at the other end of the outer sleeve 14, a nut 16 and a washer 17 mounted on the outer periphery of the screw 15, a first spring 18 mounted on the outer periphery of the screw 15 and positioned between the washer 17 and the stop plate, and a second spring 20 mounted on the outer periphery of the screw sleeve 19 and positioned between a step on the inner wall of the outer sleeve 14 and a punch fixing block 25. The inner periphery of the outer sleeve 14 has an axially extending slideway for the stop plate. The first spring 18 abuts against the washer 17 and the stop plate at its ends, maintaining smooth transmission of the threaded connection between the screw 15 and the screw sleeve 19. The second spring 20 abuts against the punch fixing block 25 and the step on the inner wall of the outer sleeve 14 at its ends, also maintaining smooth transmission of the threaded connection between the screw 15 and the screw sleeve 19. After starting the power head assembly, the brushless motor 4 drives the screw 15 to rotate through the gear box 3. The screw 15 drives the screw sleeve 19 to move forward. The outer sleeve 14 guides the movement of the screw sleeve 19. The screw sleeve 19 punches the workpiece by pushing the punch fixing block 25 and the punch 21. After punching is completed, the output end of the brushless motor 4 rotates in the opposite direction. The screw 15 drives the screw sleeve 19 to move in the opposite direction. The screw sleeve 19 drives the punch fixing block 25 and the punch 21 to move in the opposite direction through the clamping portion, thereby separating the punch 21 from the workpiece.

[0026] like Figure 1 As shown, the punching assembly is provided with a first light positioning assembly and a second light positioning assembly. The first light positioning assembly includes a first lamp bead fixing block 271 provided on the first punch die 26 and a first lamp bead 272 provided on the first lamp bead fixing block 271. The first lamp bead fixing block 271 has a first light-transmitting strip hole. The first lamp bead 272 can emit a linear infrared ray through the first light-transmitting strip hole. The second light positioning assembly includes a second lamp bead fixing block 281 provided on the first fixing frame 23 and a second lamp bead 282 provided on the second lamp bead fixing block 281. The second lamp bead fixing block 281 has a second light-transmitting strip hole. The second lamp bead 282 can emit a linear infrared ray through the second light-transmitting strip hole. The second light-transmitting strip hole is perpendicular to the first light-transmitting strip hole. The two infrared rays are perpendicular, and the X and Y directions can be positioned when punching the workpiece. After accurate positioning, the workpiece is punched by the punch 21, and the punching process is more accurate.

[0027] This embodiment can realize the processing of punching holes of different specifications by replacing the first die 26 and the punch 21, which is highly flexible, low-cost and easy to carry. When replacing, loosen the first bolt, remove the original punch 21, remove the first die 26, then insert the first die 26 of the new specification, and insert the punch 21 of the new specification through the through hole 231, the second insertion hole 262 and the first insertion hole 261. The punch 21 is inserted into the installation channel of the punch fixing block 25, and the end face of the first die 26 is adjusted to be flush with the end face of the first fixing frame 23. The first bolt is tightened to fix it tightly. The punch 21 can prevent the first die 26 and the punch fixing block 25 from falling at the first insertion hole 261 and the installation channel, thereby playing a limiting role.

[0028] Example 2

[0029] like Figure 4-Figure 6 As shown, the modular punching device proposed in this embodiment is different from the first embodiment. In this embodiment, the punching assembly in the die assembly includes a punch 21, a replaceable second die 30, and a second fixing frame 29 connected to the connecting block 22 by a bolt 24 and having a second locking space. The second die 30 is threadedly connected to a second bolt that is tightened on the second fixing frame 29. The second die 30 has a U-shaped locking channel and a third insertion hole 301 and a fourth insertion hole 302 that extend coaxially along the width of the locking channel. The third insertion hole 301 is a positioning hole, and the fourth insertion hole 302 is a punching hole. The third insertion hole 301 is coaxially distributed with the installation channel, and the punch 21 is installed in the installation channel and faces the third insertion hole 301. The workpiece to be punched is placed in the locking channel. When the punch 21 moves forward to punch, the punch 21 penetrates the workpiece and discharges the flushed waste material through the fourth insertion hole 302. The second punch die 30 is slidably mounted on the second fixing frame 29, and the punch fixing block 25 is slidably mounted in the mounting space. The punch 21 prevents the punch fixing block 25 and the second punch die 30 from falling off.

[0030] like Figure 5 As shown, the punching assembly is provided with a first light positioning assembly and a second light positioning assembly, the first light positioning assembly includes a first lamp bead fixing block 271 provided on the second die 30 and a first lamp bead 272 provided on the first lamp bead fixing block 271, the first lamp bead fixing block 271 has a first light-transmitting strip hole, the second light positioning assembly includes a second lamp bead fixing block 281 provided on the second die 30 and a second lamp bead 282 provided on the second lamp bead fixing block 281, the second lamp bead fixing block 281 has a second light-transmitting strip hole, the second light-transmitting strip hole is perpendicular to the first light-transmitting strip hole, then the two infrared rays emitted by the two lamp beads through the two light-transmitting strip holes are perpendicular, and the X-direction and Y-direction positioning can be performed on the punching workpiece. After accurate positioning, the workpiece is punched by the punch 21, and the punching process is more accurate.

[0031] In this embodiment, if punching processing of other specifications is required, the second die 30 and punch 21 of new specifications need to be replaced. The replacement process is very convenient. Loosen the second bolt, directly remove the original punch 21, then remove the second die 30, and then slide the second die 30 of the new specification onto the second fixing frame 29, insert the punch 21 of the new specification at the fourth hole 302 and the third hole 301, and then align the punch 21 of the new specification with the installation channel of the punch fixing block 25, align the end face of the second die 30 with the end face of the second fixing frame 29, tighten the second bolt, and the punch 21 can realize the anti-slip limit of the second die 30 and the punch fixing block 25 at the third hole 301 and the installation channel.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
