Description

Technical Field

[0001] This utility model belongs to the field of pin processing technology, specifically relating to a drilling device for the end of a pin component. Background Technology

[0002] A pin is a standardized structural component that can be used as a connector at the hinge of two parts, or as a safety pin in fire extinguishers and other equipment that needs to be prevented from being opened accidentally. To prevent the pin from falling off accidentally, holes need to be drilled in the side wall of the pin to install a locking pin.

[0003] In related prior art, such as Chinese Patent No. CN221675891U, a braking linkage positioning and drilling device is disclosed. This solution includes a worktable, a drive assembly fixedly connected to the top left side of the worktable, a push plate fixedly connected to the right side of the drive assembly, two sleeves fixedly connected to the right side of the push plate, a spring inside each sleeve, and a cylindrical sleeve slidably connected inside each sleeve. Clamping plates are fixedly connected to the right sides of the two cylindrical sleeves. A fixing plate is fixedly connected to the top right side of the worktable, and a protective pad is fixedly connected to the left side of the fixing plate. This solution utilizes a moving push plate to fix the clamping plate and fixing plate to the linkage, preventing it from shifting during the drilling process.

[0004] When using the above solution, only the push plate can be moved. When the clamping plate and the fixing plate fix the rod, the horizontal position of the axis of the rod with different diameters is different. This can easily cause the axis of the rod and the axis of the drill bit to not be in the same vertical plane. As a result, the above solution can only drill rods with a single diameter, and its applicability is poor. Utility Model Content

[0005] The present invention aims to provide a drilling device for the end of a pin member to solve the problem of poor applicability of the above-mentioned solutions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drilling device for the end of a pin member includes a worktable, a clamping assembly, and an adjustable stop positioning assembly. A mounting frame is fixedly installed above the worktable, and a vertical rod is slidably inserted into the bottom of the mounting frame. A drive mechanism for moving the vertical rod up and down is provided inside the mounting frame. A drill bit is provided at the bottom of the vertical rod. Grooves are provided on the top of the worktable on both the front and rear sides of the drill bit. The clamping assembly includes a bidirectional screw, which is rotatably inserted into the two grooves in the front-rear direction. The positive and negative threaded sections of the bidirectional screw are respectively fitted with first sliders in the two grooves. The first sliders are slidably disposed in the grooves, and a clamping block is fixedly installed on the top of the first slider. The inner sidewall of the clamping block protrudes from the inner sidewall of the first slider. A first driving member for driving the bidirectional screw to rotate is fixedly installed on the outer sidewall of the worktable. Two sets of stop positioning assemblies are provided and are respectively disposed on the top of the two clamping blocks.

[0008] The principle and effects of this technical solution:

[0009] In the initial state, the two first sliders are far apart. When drilling the pin, the pin is placed on the top of the worktable. Then, the left and right positions of the pin are adjusted by the stop positioning component according to the drilling position of the pin. Then, the first drive component drives the bidirectional screw to rotate. The two first sliders move closer to each other as the bidirectional screw rotates. When the clamping blocks on the top of the two first sliders clamp the pin, the pin is located directly below the drill bit. The drill bit is started and the vertical rod is lowered by the drive mechanism so that the drill bit drills the pin.

[0010] With the above configuration, the two first sliders move simultaneously towards each other by rotating the bidirectional screw, thereby clamping the pins together. When fixing pins of different diameters, this device keeps the axis of the pin and the axis of the drill bit in the same vertical plane, improving the applicability of the device and the hole quality of the pins.

[0011] In this invention, guide rods are fixedly arranged on the left and right sides of the bidirectional screw within the groove, and the first slider is slidably sleeved on the corresponding guide rod.

[0012] By using the above setup, the guide rod is used to prevent the first slider from rotating, thereby achieving the purpose of making the first slider move with the rotation of the bidirectional screw.

[0013] In this utility model, the stop positioning assembly includes a threaded rod, a second slider, and a stop bar. The top of each clamping block is provided with a threaded rod that rotates in the left and right direction. The threaded rod is fitted with a second slider. The bottom of the second slider slides against the top of the clamping block. An L-shaped stop bar is fixedly provided on one side of each of the two second sliders that are close to each other.

[0014] The principle and effects of this technical solution:

[0015] First, rotate the threaded rod of one of the stop positioning components. Because the clamping block prevents the second slider from rotating, the second slider moves left and right as the threaded rod rotates. After moving the stop rod of one of the stop positioning components to the appropriate position, move the second slider and stop rod of the other stop positioning component during the rotation of the bidirectional screw, so that the two stop rods contact the two ends of the pin respectively.

[0016] By adjusting the placement of the pins by moving the two second sliders left and right, it is possible to ensure that the same part of multiple pins is drilled, thereby further improving the hole quality of the pins.

[0017] In this invention, the top of the clamping block is provided with scale lines along the left-right direction.

[0018] With the above configuration, the pin can be conveniently placed between the two stop bars when the two clamping blocks move in opposite directions.

[0019] In this invention, the top of the workbench is recessed with an insertion hole directly below the drill bit.

[0020] The above settings ensure that the drill bit penetrates the pin, thus ensuring the quality of the hole.

[0021] In this invention, the top of the workbench is provided with a fan-shaped limiting groove below the drill bit in the left-right direction.

[0022] The above settings can improve the stability of the pin when it is placed, and prevent it from rolling on the top surface of the worktable.

[0023] In this invention, anti-slip pads are fixedly provided on the side of each of the two clamping blocks that are close to each other.

[0024] By adopting the above settings, vertical displacement of the pin can be avoided during the clamping process of the two clamping blocks, thereby further improving the hole forming quality of the pin. Attached Figure Description

[0031] Example:

[0032] As attached Figure 1-4 As shown, this utility model discloses a drilling device for the end of a pin member, including a worktable 10, a clamping assembly, and an adjustable stop positioning assembly. A mounting frame 11 is fixedly mounted above the worktable 10, and a vertical rod 20 is slidably inserted into the bottom of the mounting frame 11. A driving mechanism for moving the vertical rod 20 up and down is provided inside the mounting frame 11. A drill bit 21 is provided at the bottom of the vertical rod 20. Grooves 12 are provided on the top of the worktable 10 on both the front and rear sides of the drill bit 21. The clamping assembly includes a bidirectional screw 31, which is rotatably inserted into the two grooves 12 in the front-rear direction. The positive and negative threaded sections of 1 are respectively fitted with the first slider 32 in the two grooves 12. The first slider 32 is slidably disposed in the groove 12, and the top of the first slider 32 is fixedly disposed with a clamping block 33. The inner sidewall of the clamping block 33 protrudes from the inner sidewall of the first slider 32. The outer sidewall of the worktable 10 is fixedly disposed with a first driving member 34 that drives the bidirectional screw 31 to rotate. The stop positioning assembly is provided in two sets and is disposed on the top of the two clamping blocks 33. The driving mechanism includes a rack and a gear that mesh with each other. The rack is fixedly disposed vertically on the surface of the vertical rod 20, and the gear is rotatably disposed in the mounting bracket 11.

[0033] In this embodiment, guide rods 13 are fixedly arranged on the left and right sides of the bidirectional screw 31 in the groove 12, and the first slider 32 is slidably sleeved on the corresponding guide rod 13.

[0034] In this embodiment, the stop positioning assembly includes a threaded rod 41, a second slider 42, and a stop bar 43. The top of each clamping block 33 is provided with a threaded rod 41 that rotates in the left and right direction. The threaded rod 41 is fitted with a second slider 42. The bottom of the second slider 42 slides against the top of the clamping block 33. An L-shaped stop bar 43 is fixedly provided on one side of each of the two second sliders 42. A second driving member that is connected to the corresponding threaded rod 41 is fixedly provided on the end wall of the clamping block 33.

[0035] In this embodiment, the top of the clamping block 33 is provided with scale lines 35 along the left and right direction.

[0036] In this embodiment, the top of the workbench 10 is recessed with an insertion hole 15 directly below the drill bit 21.

[0037] In this embodiment, the top of the workbench 10 is provided with a fan-shaped limiting groove 14 below the drill bit 21 in the left-right direction.

[0038] In this embodiment, anti-slip pads 36 are fixedly provided on the side of the two clamping blocks 33 that are close to each other.

[0039] The specific implementation process is as follows:

[0040] In the initial state, the two first sliders 32 are far apart from each other. When drilling the pin, the pin is placed on the top of the worktable 10. Then, the left and right positions of the pin are adjusted by the stop positioning component according to the drilling position of the pin. Then, the first drive 34 drives the bidirectional screw 31 to rotate. The two first sliders 32 move closer to each other as the bidirectional screw 31 rotates. When the clamping blocks 33 on the top of the two first sliders 32 clamp the pin, the pin is located directly below the drill bit 21. The drill bit 21 is started and the vertical rod 20 is moved down by the drive mechanism so that the drill bit 21 drills the pin.

[0041] First, rotate the threaded rod 41 of one of the stop positioning components. Because the clamping block 33 prevents the second slider 42 from rotating, the second slider 42 moves left and right as the threaded rod 41 rotates. After moving the stop rod 43 of one of the stop positioning components to the appropriate position, move the second slider 42 and the stop rod 43 of the other stop positioning component while rotating the bidirectional screw 31, so that the two stop rods 43 contact the two ends of the pin respectively.

[0042] During drilling, the drill cuttings are located between the two clamping blocks 33. Since the inner wall of the clamping block 33 protrudes from the inner wall of the first slider 32, when the outer walls of the two first sliders 32 respectively abut against the two grooves 12 at opposite ends, the inner wall of the clamping block 33 blocks the top of the groove 12 near the drill bit 21, preventing the drill cuttings from falling into the groove 12.

[0043] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
