Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a drilling device for machining the slewing platform of an excavator. Background Technology

[0002] An excavator, also known as a digger, is a type of earthmoving machinery that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile. The slewing platform is a crucial component of the excavator, housing key parts such as its control and operating mechanisms. To facilitate the securing of these important components, mounting holes need to be drilled around the slewing platform.

[0003] Currently, when drilling holes on the slewing platform of an excavator, it is usually fixed to a drilling support platform. However, when the slewing platform is flipped from one side to the other for drilling, the operator needs to manually release the limit switch of the slewing platform fixed to the drilling support platform and then re-fix it for drilling. This operation is cumbersome, making it inconvenient for the equipment to drill holes on different sides of the slewing platform and reducing work efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling device for machining the slewing platform of an excavator, thereby solving the problem mentioned in the background technology that it is inconvenient to drill holes on different surfaces of the slewing platform, thus reducing work efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: A drilling device for processing excavator slewing platforms, comprising a worktable and a base, the worktable being mounted on the base, a fixed frame welded to the top of the base, a servo motor mounted on the top of the base inside the fixed frame, the output end of the servo motor penetrating the fixed frame and connected to a first threaded rod, the top end of the first threaded rod being rotatably connected to the bottom end of the worktable, a U-shaped frame threadedly connected to the first threaded rod, control boards fixedly connected to both top ends of the U-shaped frame, and control frames rotatably connected to the two control boards at their adjacent ends. Each frame has a control slot at one end close to the other. Two sliding blocks are slidably connected inside each control slot. Two clamping bars are fixedly connected between the two sliding blocks. A stepper motor connected to the control frame is installed at one end of the control plate. Two bidirectional threaded rods are rotatably connected inside each of the two control slots. Gear plates are threaded onto each of the two bidirectional threaded rods. Rotating handles are connected to both ends of the two bidirectional threaded rods through the control frame. Positioning teeth that mate with the gear plates are provided at the top and bottom of each of the four sliding blocks. A mounting bracket is welded to the top of the base. A drilling device is installed on the inner upper side wall of the mounting bracket.

[0008] By adopting the above technical solution, the workpiece is placed on the worktable, and the two clamping bars are pushed to move, so that the two clamping bars cooperate to clamp and fix the workpiece. At this time, rotating the rotating handle drives the bidirectional threaded rod to rotate, thereby driving the two toothed plates to move, so that the toothed plates mesh with the positioning teeth, limiting and fixing the sliding block, and preventing the clamping bars from shaking. This clamps and fixes the workpiece. At this time, a drilling device can be used to drill holes in the workpiece. The drilling device mounted on the mounting frame can be adjusted in position to facilitate drilling at different positions of the workpiece. When drilling is required on the reverse side, the servo motor is started to drive the first threaded rod to rotate, and the first threaded rod drives the U-shaped frame to move, thereby driving the control board to move, thereby moving the workpiece away from the worktable. At this time, the stepper motor is started to drive the control board to rotate 180°, thereby causing the workpiece to flip. Then, the servo motor is started to rotate in the opposite direction, thereby moving the workpiece downward, so that the bottom of the workpiece is close to the worktable. At this time, the drilling device can be started to drill holes in the workpiece, which facilitates drilling holes on different sides of the rotary platform and achieves the purpose of improving work efficiency.

[0009] Optionally, both control frames have multiple evenly distributed receiving slots at their respective ends that are close to each other. The receiving slots are equipped with springs, and one end of the springs is connected to an auxiliary contact.

[0010] By adopting the above technical solution, when the clamping bar clamps the workpiece, the spring pushes the auxiliary contacts to move, and multiple auxiliary contacts abut against different positions of the workpiece, so that multiple auxiliary contacts can be inserted into the inner hole or gap of the workpiece, preventing the workpiece from slipping and falling between the two clamping bars, thereby improving the stability of the equipment.

[0011] Optionally, the auxiliary contact is provided with a stop block that cooperates with the receiving groove.

[0012] By adopting the above technical solution, the stop block is used to stop the auxiliary contact, preventing the auxiliary contact from falling out of the receiving groove and improving the stability of the auxiliary contact.

[0013] Optionally, both control boxes have a buffer pad at one end close to each other.

[0014] By adopting the above technical solution, the buffer pad is used to provide cushioning between the workpiece and the clamping bar, reducing the probability of the workpiece being crushed and damaged.

[0015] Optionally, two corresponding limiting grooves are provided on the inner side wall of the U-shaped frame, and two limiting blocks are fixedly connected to the worktable, with the two limiting blocks respectively inside the two limiting grooves.

[0016] By adopting the above technical solution, the limiting block and the limiting slide groove cooperate to limit the U-shaped frame and prevent the U-shaped frame from shaking or deviating, thereby preventing the processed parts from shaking or deviating, and thus achieving the purpose of improving the stability of the equipment.

[0017] (III) Beneficial Effects

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] This drilling equipment for machining excavator slewing platforms places the workpiece on the worktable and moves two clamping bars, causing them to engage and clamp the workpiece. Rotating the rotating handle then drives a double-threaded rod, which in turn moves two toothed plates, causing them to mesh with positioning teeth and limit the sliding block, preventing the clamping bars from wobbling. The drilling device, mounted on a mounting frame, can be adjusted to position the workpiece at different locations. When drilling is required on the reverse side, the servo motor is started to drive the first threaded rod to rotate. The first threaded rod drives the U-shaped frame to move, which in turn moves the control board, thus moving the workpiece away from the worktable. At this time, the stepper motor is started to drive the control board to rotate 180°, which causes the workpiece to flip. Then, the servo motor is started to rotate in the opposite direction, which causes the workpiece to move downward, so that the bottom of the workpiece is close to the worktable. At this time, the drilling device can be started to drill the workpiece, which facilitates drilling on different sides of the rotary platform and improves work efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-5A drilling device for machining the slewing platform of an excavator includes a worktable 1 and a base 2. The worktable 1 is mounted on the base 2. A fixed frame 3 is welded to the top of the base 2. A servo motor 4 is mounted inside the fixed frame 3 at the top of the base 2. The output end of the servo motor 4 passes through the fixed frame 3 and is connected to a first threaded rod 5. The top end of the first threaded rod 5 is rotatably connected to the bottom end of the worktable 1. A U-shaped frame 6 is threaded onto the first threaded rod 5. Control plates 7 are fixedly connected to both top ends of the U-shaped frame 6. Control frames 8 are rotatably connected to the two control plates 7 at their adjacent ends. One end of the control plate 7 has a control slot, and two sliding blocks 9 are slidably connected inside each control slot. Two cooperating clamping bars 10 are fixedly connected between the two sliding blocks 9. One end of the control plate 7 is equipped with a stepper motor 11 connected to the control frame 8. Two bidirectional threaded rods 12 are rotatably connected inside each control slot. Two toothed plates 13 are threaded onto each of the two bidirectional threaded rods 12. Both ends of the two bidirectional threaded rods 12 pass through the control frame 8 and are connected to a rotating handle 14. The top and bottom ends of the four sliding blocks 9 are provided with positioning teeth that cooperate with the toothed plates 13. A mounting bracket 15 is welded to the top of the base 2. The mounting bracket 15 has an inner... A drilling device 16 is installed on the upper side wall. The workpiece is placed on the worktable 1, and the two clamping bars 10 are pushed to move, engaging to clamp and fix the workpiece. At this time, rotating the rotating handle 14 drives the bidirectional threaded rod 12 to rotate, thereby moving the two toothed plates 13, causing them to mesh with the positioning teeth, limiting and fixing the sliding block 9 to prevent the clamping bars 10 from shaking. The drilling device 16 can then be used to drill holes in the workpiece. The drilling device 16, mounted on the mounting bracket 15, can be adjusted in position to facilitate drilling different workpieces. Drilling is performed on the worktable. When drilling is required on the reverse side, the servo motor 4 is started to drive the first threaded rod 5 to rotate. The first threaded rod 5 drives the U-shaped frame 6 to move, thereby driving the control board 7 to move and thus moving the workpiece away from the worktable 1. At this time, the stepper motor 11 is started to drive the control board 7 to rotate 180°, thereby causing the workpiece to flip. Then, the servo motor 4 is started to rotate in the opposite direction, thereby moving the workpiece downward so that the bottom of the workpiece is close to the worktable 1. At this time, the drilling device 16 can be started to drill the workpiece, which facilitates drilling on different sides of the rotary platform and improves work efficiency.

[0029] Reference Figure 4 and Figure 5Both control frames 8 have multiple evenly distributed receiving slots at their close ends. Springs 17 are installed inside the receiving slots, and one end of the springs 17 is connected to auxiliary contacts 18. When the clamping bars 10 clamp the workpiece, the springs 17 push the auxiliary contacts 18 to move. The multiple auxiliary contacts 18 abut against different positions of the workpiece, so that the multiple auxiliary contacts 18 can be inserted into the inner hole or gap of the workpiece, preventing the workpiece from slipping and falling between the two clamping bars 10, thereby improving the stability of the equipment.

[0030] Reference Figure 4 and Figure 5 The auxiliary contact 18 is provided with a stop block 19 that cooperates with the receiving groove. The stop block 19 is used to stop the auxiliary contact 18, prevent the auxiliary contact 18 from falling out of the receiving groove, and improve the stability of the auxiliary contact 18.

[0031] Reference Figures 2-5 Both control boxes 8 have a buffer pad 20 at one end close to each other. The buffer pad 20 is used to provide cushioning between the workpiece and the clamping bar 10, reducing the probability of the workpiece being crushed and damaged.

[0032] Reference Figure 2 and Figure 3 Two corresponding limiting grooves 21 are provided on the inner side wall of the U-shaped frame 6. Two limiting blocks 22 are fixedly connected to the worktable 1. The two limiting blocks 22 are respectively connected to the inside of the two limiting grooves 21. The limiting blocks 22 cooperate with the limiting grooves 21 to limit the U-shaped frame 6 and prevent the U-shaped frame 6 from shaking or tilting, thereby preventing the processed parts from shaking or tilting, and thus achieving the purpose of improving the stability of the equipment.

[0033] It should be further explained that the servo motor 4, stepper motor 11, and drilling device 16 in this embodiment are all conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. Furthermore, the servo motor 4, stepper motor 11, and drilling device 16 are all equipped with corresponding control switches. The installation position of the control switches can be selected according to actual usage requirements to facilitate operation and control by the operator.

[0034] In summary, the working principle and process of the drilling equipment used for machining the excavator's slewing platform are as follows: First, the workpiece is placed on the worktable 1. The two clamping bars 10 are then moved, engaging to clamp and fix the workpiece. Next, the rotating handle 14 rotates the bidirectional threaded rod 12, which in turn moves the two toothed plates 13, causing them to mesh with the positioning teeth. This limits and fixes the sliding block 9, preventing the clamping bars 10 from shaking, thus clamping and fixing the workpiece. At this point, the drilling device 16 can be used to drill holes in the workpiece. The drilling device 16, mounted on the mounting frame 15, can perform positioning... The adjustment position facilitates drilling at different locations on the workpiece. When drilling is required on the reverse side, the servo motor 4 is started to drive the first threaded rod 5 to rotate, which in turn drives the U-shaped frame 6 to move, thereby moving the control board 7 and moving the workpiece away from the worktable 1. At this time, the stepper motor 11 is started to drive the control board 7 to rotate 180°, thereby causing the workpiece to flip. Then, the servo motor 4 is started to rotate in the opposite direction, thereby moving the workpiece downward so that the bottom of the workpiece is close to the worktable 1. At this time, the drilling device 16 can be started to drill holes in the workpiece, which facilitates drilling on different surfaces of the rotary platform and improves work efficiency.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
