Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-4As shown, a sealing strip drilling device includes: a workbench 100, a support base 200, and an electric cylinder 301. The support base 200 is installed on one side of the top of the workbench 100, and the electric cylinder 301 is installed on both sides of the top of the support base 200. A lifting seat 302 is installed at the output end of the electric cylinder 301. Several sliding seats 303 are slidably connected inside the lifting seat 302. A drilling machine 304 is installed at the bottom of the sliding seat 303. A sliding rod 305 is slidably connected inside the sliding seat 303. A limiting plate 308 is installed at the top of the sliding rod 305. A sliding groove 309 matching the position of the limiting plate 308 is opened inside the sliding seat 303. A fixing piece 306 is fixedly connected to the bottom end of the sliding rod 305. The fixing piece 306 is provided with a tool to avoid the drilling head of the drilling machine 304. The sealing strip is perforated by a first spring 307 mounted on one side of the top of the fixing plate 306. A sliding seat 303 is mounted on the top of the first spring 307. The first spring 307 passes through the outer wall of the sliding rod 305. The sliding seat 303 is provided with a fixing component for fixing the position of the sliding seat 303. By activating the electric cylinder 301, the lifting seat 302 is moved, causing the lifting seat 302 to move the sliding seat 303 and the drilling machine 304 up and down to drill holes in the sealing strip. During drilling, the fixing plate 306 first contacts the clamping block 503. When the clamping block 503 is pressed against the fixing plate 306, the electric cylinder 301 continues to descend, causing the sliding rod 305 and the first spring 307 to be squeezed and move upward. At this time, the output end of the drilling machine 304 passes through the fixing plate 306 to drill holes in the sealing strip, which can effectively avoid accidental injury to the operator.

[0028] In one embodiment, such as Figure 2 and Figure 3 As shown, the fixing assembly includes an L-shaped plate 401, which is installed on the top of one side of the sliding seat 303. The lifting seat 302 has a sliding groove 402 that matches the L-shaped plate 401 on the side away from the support seat 200. The L-shaped plate 401 is slidably connected in the sliding groove 402. A threaded rod 403 is threadedly connected to one side of the L-shaped plate 401. A washer 404 is installed on the side of the threaded rod 403 near the lifting seat 302. The washer 404 is in movable contact with the lifting seat 302. By rotating the threaded rod 402, the washer 404 is moved and pressed against the lifting seat 302, thereby fixing the position of the L-shaped plate 401.

[0029] In one embodiment, such as Figure 2 and Figure 3As shown, the clamping assembly includes a clamping groove 501, which is located on the top of the workbench 100. Several slide rails 502 are installed on both sides of the clamping groove 501. A clamping block 503 is slidably connected to the slide rail 502. Fixing sleeves 505 are installed on both sides of the top of the clamping block 503. A punching groove 504 is provided in the middle of the clamping block 503. The workbench 100 is provided with a disassembly assembly for quickly installing the clamping block 503. By placing the clamping block 503 on the slide rail 502, the movement position of the clamping block 503 is guided. At the same time, the punching groove 504 facilitates the punching machine 304 to punch holes in the sealing strip.

[0030] In one embodiment, such as Figure 2 and Figure 4 As shown, the disassembly assembly includes a support plate 601, which is installed on both sides of the top of the workbench 100. An electric push rod 602 is installed on the inner top wall of the support plate 601. A fixing block 603 is installed at the output end of the electric push rod 602. A second spring 604 is installed inside the fixing block 603. A step rod 605 passes through the second spring 604. One end of the step rod 605 is slidably connected to the fixing block 603, and the step rod 605 is fixedly connected to the close-to-close ends of the second spring 604. A limiting plate 607 is installed on the outer wall of the step rod 605, and the limiting plate 607 is slidably connected to the interior of the fixing block 603. The top of the clamping block 503 is slidably connected to the fixing block 603, and the inside of the fixing sleeve 505 is provided with a slot that matches the step rod 605. By pressing the step rod 605 simultaneously, the step rod 605 drives the second spring 604 to move. At this time, the clamping block 503 is sleeved on the fixing block 603. The step rod 605 slides inside the clamping block 503. When it slides to the position of the slot, the step rod 605 returns to its original position under the action of the second spring 604 and is locked inside the slot, fixing the clamping block 503 to the output end of the electric push rod 602. Then, by starting the electric push rod 602, the clamping block 503 can be moved up and down to clamp and position the sealing strip.

[0031] In one embodiment, such as Figure 1 As shown, the two electric cylinders 301 output synchronously to prevent the lifting seat 302 from shifting during drilling.

[0032] In one embodiment, such as Figure 2 As shown, the lifting seat 302 has a sliding groove inside that matches the sliding seat 303, which facilitates the adjustment of the spacing between multiple punching machines 304.

[0033] In one embodiment, such as Figure 2As shown, the output end of the punching machine 304 is slidably connected to the fixing plate 306; this facilitates the punching machine 304 to punch holes in the sealing strip.

[0034] The above embodiment discloses a sealing strip drilling device. First, a clamping block 503 corresponding to the sealing strip of different sizes is selected and installed inside the clamping groove 501. The clamping block 503 is placed on the slide rail 502, guiding its movement. The sealing strip can then be placed inside the clamping block 503. The drilling groove 504 facilitates the drilling of the sealing strip by the drilling machine 304. The position of the clamping block 503 is then fixed. Simultaneously pressing the step rod 605 causes the second spring 604 to move, allowing the clamping block 503 to be fitted onto the fixing block 603. The step rod 605 slides inside the clamping block 503. When it slides to the slot position, the step rod 605 resets under the action of the second spring 604 and locks into the slot, thus fixing the clamping block 503. Then, the device can be used to... The electric push rod 602 is activated, causing the clamping block 503 to move up and down to clamp and position the sealing strip. Then, the spacing between the punching machines 304 can be adjusted by first moving multiple sliding seats 303. Subsequently, the threaded rod 402 is rotated to move the gasket 404 and make the gasket 404 press against the lifting seat 302, thereby fixing the position of the L-shaped plate 401. At this time, the electric cylinder 301 can be activated to move the lifting seat 302, which in turn moves the sliding seat 303 and the punching machine 304 to rise and fall, punching holes in the sealing strip. During punching, the fixing plate 306 first contacts the clamping block 503. When the clamping block 503 presses against the fixing plate 306, the electric cylinder 301 continues to descend, causing the sliding rod 305 and the first spring 307 to be squeezed and move upward. At this time, the output end of the punching machine 304 passes through the fixing plate 306 to punch holes in the sealing strip, which can effectively avoid accidental injury to the operator.
