Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stone processing technology and relates to a stone drilling device that is easy to operate. Background Technology
[0002] As a common building and decorative material, stone often requires various processing techniques during its production, among which drilling is a crucial step. Whether it's natural marble, granite, or artificial stone, precise drilling is necessary according to design requirements when creating countertops, wall decorations, or special shapes.
[0003] When drilling holes in round or square stone products, existing stone drilling equipment can reliably clamp them, but the clamping blocks are usually clamped or released using a screw and nut. To ensure sufficient space for loading and unloading the stone, the screw must be rotated a sufficient number of times each time to create enough space between the two clamping blocks, making the operation time-consuming. Therefore, designing a more user-friendly stone drilling device to solve these problems is particularly necessary. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a convenient stone drilling device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a convenient stone drilling device, comprising a base, a drilling machine body on the base, and a stone drill bit detachably fixed on the main shaft of the drilling machine body. The device is characterized in that multiple mounting rods are fixedly connected to one side of the base, and fixed clamping blocks are fixedly connected to the mounting rods; a base plate is fixedly connected to the other side of the base; a guide post is horizontally fixed on the base plate; a guide block is slidably connected to the guide post; a main movable platform is fixedly connected to the guide block; a guide strip is horizontally fixed on the main movable platform; an auxiliary movable platform is slidably connected to the guide strip; a movable clamping block is fixedly connected to the auxiliary movable platform; a first limiting hole is provided on the guide strip near the fixed clamping block; a second limiting hole is provided on the auxiliary movable platform; limiting pins are inserted into the first and second limiting holes; and abutment blocks are fixed at both ends of the guide strip. A lead screw is horizontally rotatably connected to the base plate; a nut is threaded onto the lead screw; the nut is connected to the main movable platform via a nut seat; and a handwheel is installed at the end of the lead screw.
[0006] Both the fixed clamping block and the movable clamping block are V-shaped.
[0007] Both the fixed and movable clamping blocks are equipped with elastic anti-slip pads.
[0008] The limiting pin is made of steel, and a magnet is fixed inside the limiting hole.
[0009] An operating ring is also fixed to the limiting pin.
[0010] By adopting the above technical solution, the beneficial effects of this utility model are:
[0011] This utility model utilizes the cooperation between the main movable platform and the auxiliary movable platform. During clamping operations, the auxiliary movable platform is restricted and locked, and the handwheel is operated to firmly clamp the stone between the fixed clamping block and the movable clamping block. When removing or placing the stone, the auxiliary movable platform is unlocked, allowing the movable clamping block to quickly move away from the fixed clamping block, thus achieving convenient clamping and removal operations.

[0017] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0018] like Figure 1-4As shown, this easy-to-operate stone drilling device includes a base 1, on which a drilling machine body is mounted. The drilling machine body uses an existing device that allows the stone drill bit 9 to move accordingly, thereby completing the stone drilling. This is existing technology. The stone drill bit 9 is detachably fixed on the main shaft 10 of the drilling machine body. Multiple mounting rods 8 are fixedly connected to one side of the base 1, and fixed clamping blocks 7 are fixedly connected to the mounting rods 8. A base plate 2 is fixedly connected to the other side of the base 1. A guide post 12 is horizontally fixed on the base plate 2. A guide block 13 is slidably connected to the guide post 12. A main movable table 4 is fixedly connected to the guide block 13. A guide strip 15 is horizontally fixed on the main movable table 4. An auxiliary movable table 5 is slidably connected to the guide strip 15. A movable clamping block 6 is fixedly connected to the auxiliary movable table 5. A limiting hole 15a is also provided on the end of the guide strip 15 near the fixed clamping block 7. A limiting hole 15a is also provided on the auxiliary movable table 5. A limiting pin 17 is inserted into the second limiting hole 5a and the first limiting hole 15a. In practice, by moving the auxiliary movable platform 5 so that its inner abutment block 16 contacts, the limiting pin 17 is inserted into the second limiting hole 5a and the first limiting hole 15a to lock the position of the auxiliary movable platform 5. After drilling is completed, the screw 14 is rotated slightly by the handwheel 3, and then the limiting pin 17 is pulled out to push the auxiliary movable platform 5 to contact the outer abutment block 16, so that there is enough operating space for picking up and putting down the stone. Abutment blocks 16 are also fixed at both ends of the guide bar 15. The screw 14 is also horizontally rotatably connected to the base plate 2. A nut is threaded on the screw 14. The nut is connected to the main movable platform 4 through the nut seat. The handwheel 3 is also installed at the end of the screw 14. In this embodiment, the structure and connection method of the nut and nut seat are the existing ones.
[0019] Both the fixed clamping block 7 and the movable clamping block 6 are V-shaped.
[0020] Both the fixed clamping block 7 and the movable clamping block 6 are fixed with elastic anti-slip pads 11.
[0021] The limiting pin 17 is made of steel, and a magnet 19 is fixed inside the limiting hole 15a. With this structure, the magnet 19 can hold the limiting pin 17 in place and prevent it from accidentally coming out.
[0022] An operating ring 18 is also fixed on the limiting pin 17.
[0023] This utility model utilizes the cooperation between the main movable platform 4 and the auxiliary movable platform 5. During clamping operations, the auxiliary movable platform 5 is restricted and locked, and the handwheel 3 is operated to firmly clamp the stone between the fixed clamping block 7 and the movable clamping block 6. When removing or placing the stone, the auxiliary movable platform 5 is unlocked, allowing the movable clamping block 6 to quickly move away from the fixed clamping block 7, thereby achieving convenient clamping and removal operations.
[0024] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
