Description

Technical Field

[0001] This utility model relates to the field of workpiece hole-making technology, specifically a workpiece clamping structure for precise perforation. Background Technology

[0002] Many workpieces require secondary processing after production, one of which is drilling. Drilling requires fixing and positioning the workpiece to achieve precise drilling. Existing drilling devices use tooling for clamping and fixing before precise drilling. However, the waste generated during drilling lacks a good collection mechanism, leading to increased ambient temperature and a large amount of dust and waste as processing progresses, affecting processing safety. Therefore, a workpiece clamping structure for precise drilling is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A precision workpiece clamping structure for drilling includes a clamping mechanism, a protective mechanism, and a drilling mechanism. The clamping mechanism includes a worktable, a screen connected to the middle of the worktable, a telescopic rod disposed at the bottom of the worktable, and a clamping plate connected to the output end of the telescopic rod. The protective mechanism includes a protective shell mounted on the top of the worktable, a top plate connected to the top of the protective shell, a transparent glass disposed at the bottom center of the protective shell, and a dust suction port mounted on the back of the protective shell. The drilling mechanism includes a lifting cylinder mounted on the top of the top plate, a lifting rod connected to the output end of the lifting cylinder, a movable plate fixedly mounted at the bottom end of the lifting rod, a radiator disposed at the bottom of the movable plate, a drilling motor mounted in the middle of the radiator, and a drill bit connected to the output end of the drilling motor.

[0006] Preferably, an anti-deviation rod is installed on the top of the side of the clamping plate connected to the telescopic rod, and the anti-deviation rod is inserted into the workbench.

[0007] Preferably, the bottom of the back of the protective shell extends to the bottom of the workbench and is fixedly installed with a slide rod, and a waste chip trough is slidably connected to the slide rod, the waste chip trough being located directly below the screen.

[0008] Preferably, limit rods are provided on both sides of the top of the movable plate, and the top end of the limit rods penetrates through the top plate and is slidably connected to the top plate.

[0009] Preferably, the drill bit is located directly above the screen.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0011] In this invention, a sliding rod is used to make the waste chip trough slide on it and set below the screen. The waste chips generated by the opening will fall into the waste chip trough. Therefore, a water source is set inside the waste chip trough. When the high-temperature particles come into contact with the water source, the water will evaporate. The evaporated water vapor will come into contact with the workpiece to achieve rapid cooling. At the same time, it will adsorb the dust inside the protective shell and discharge it to the outside through the dust suction port, ensuring the stability of the opening environment and reducing the interference of dust.

[0018] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a workpiece clamping structure for precise perforation.

[0020] Example:

[0021] Combination Figure 1-2As shown, this utility model provides a workpiece clamping structure for precision drilling, including a clamping mechanism, a protective mechanism, and a drilling mechanism. The clamping mechanism includes a worktable 110, a screen 120 connected to the middle of the worktable 110, a telescopic rod 130 set at the bottom of the worktable 110, and a clamping plate 140 connected to the output end of the telescopic rod 130. An anti-deviation rod 150 is installed on the top of the side of the clamping plate 140 connected to the telescopic rod 130 and is inserted into the worktable 110. The protective mechanism includes a protective shell 210 installed on the top of the worktable 110, a top plate 220 connected to the top of the protective shell 210, a transparent glass 250 set at the bottom center of the protective shell 210, a dust suction port 260 assembled on the back of the protective shell 210, and a bottom of the back of the protective shell 210. A slide bar 230 is fixedly installed below the workbench 110. A waste chip trough 240 is slidably connected to the slide bar 230. The waste chip trough 240 is located directly below the screen 120. The drilling mechanism includes a lifting cylinder 310 installed on the top of the top plate 220, a lifting rod 320 connected to the output end of the lifting cylinder 310, a movable plate 330 fixedly installed at the bottom of the lifting rod 320, a radiator 340 set at the bottom of the movable plate 330, a drilling motor 350 installed in the middle of the radiator 340, and a drill bit 360 connected to the output end of the drilling motor 350. Limiting rods 331 are provided on both sides of the top of the movable plate 330. The top of the limiting rods 331 penetrates the top plate 220 and is slidably connected to the top plate 220. The drill bit 360 is located directly above the screen 120.

[0022] Specifically, the screen holes of the screen 120 allow the waste debris generated from the opening to fall into the waste debris trough 240, preventing high-temperature particles from solidifying on other structures and becoming difficult to clean. At the same time, after the high-temperature particles fall into the waste debris trough 240, the moisture inside will evaporate to produce water vapor, which will cool the workpiece. This allows the workpiece after the opening to cool down quickly, improving the reliability of the device.

[0023] In addition, the protective shell 210 is used to shield the top of the worktable 110, which effectively prevents splashing and improves the safety of processing. Furthermore, the transparent glass 250 is provided for easy observation, avoiding the difficulty of remedying mistakes after drilling, thus improving the practicality of the device.

[0024] The working principle and usage process of this utility model are as follows: First, start the device and place the workpiece that needs to be drilled on the screen 120. Then, the workpiece is clamped by the clamping plates 140 on both sides. The telescopic rods 130 on both sides are extended and retracted by the control system to change the position of the workpiece on the screen 120, thereby realizing automated and precise drilling. After the position is determined, start the lifting cylinder 310. The lifting cylinder 310 controls the lifting of the movable plate 330. The drilling motor 350 controls the rotation of the drill bit 360. Drilling can be performed after the workpiece is fixed. After drilling is completed, the workpiece can be taken out and the drilling process of the next workpiece can be carried out.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
