Detailed implementation manners

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figure 1 - Figure 4 shown, the present utility model provides a drilling mechanism of a machine tool, including an operating platform 1. A clamping mechanism 2 is arranged on the top of the operating platform 1. A support frame 3 is fixedly connected to the top of the operating platform 1. An electric push rod 4 is fixedly installed on the top of the support frame 3. The telescopic end of the electric push rod 4 movably penetrates through the support frame 3. The telescopic end of the electric push rod 4 is fixedly connected to a fixing plate 5. A drilling mechanism 6 is arranged at the bottom of the fixing plate 5. A transparent cover 7 is arranged on the outer surface of the fixing plate 5. A placing groove 8 is formed inside the transparent cover 7. A first fixing rod 9 is fixedly connected inside the placing groove 8. A moving block 10 is sleeved on the outer surface of the first fixing rod 9. One side of the moving block 10 is fixedly connected to the fixing plate 5. A return spring 11 is sleeved on the outer surface of the first fixing rod 9. A chip suction mechanism 12 is arranged on one side of the transparent cover 7.

[0023] The effect achieved by the entire Embodiment 1 is that by starting the electric push rod 4, the electric push rod 4 drives the fixed plate 5 to move downward, and the fixed plate 5 drives the drilling mechanism 6 to move downward. The workpiece is drilled through the drilling mechanism 6. When the fixed plate 5 moves downward, the fixed plate 5 drives the transparent cover 7 to move downward. The transparent cover 7 first contacts the operation platform 1, so that the transparent cover 7 covers the periphery of the workpiece. As the drilling mechanism 6 moves downward, the moving block 10 moves on the first fixed rod 9 and compresses the return spring 11, so that the transparent cover 7 maintains close contact with the operation platform 1 through the elastic force of the return spring 11, thereby preventing the phenomenon of chip splashing when drilling the workpiece, and solving the problem that it is difficult to protect the periphery of the drilling during the drilling of the workpiece, resulting in some chips splashing during the drilling process.

[0024] Embodiment 2: As Figure 1 - Figure 4 shown, the clamping mechanism 2 includes a rectangular groove 201 opened at the top of the operation platform 1. A second fixed rod 202 is fixedly connected in the rectangular groove 201. Two support plates 203 are fixedly connected to the bottom of the operation platform 1. A bidirectional threaded rod 204 is rotatably connected to the opposite sides of the two support plates 203. A clamping plate 205 is sleeved on the outer surfaces of the bidirectional threaded rod 204 and the second fixed rod 202. A first driving motor 206 is fixedly installed on one side of one of the support plates 203. The output end of the first driving motor 206 penetrates through one of the support plates 203 and is fixedly connected to the smooth end of the bidirectional threaded rod 204. The drilling mechanism 6 includes a second driving motor 601 fixedly installed at the bottom of the fixed plate 5. The output end of the second driving motor 601 is provided with a drill bit 602. The chip suction mechanism 12 includes a dust suction pump 121 installed on the top of the support frame 3. A collection box 122 is installed on the top of the support frame 3. The input end of the dust suction pump 121 is fixedly communicated with a telescopic pipe 123. One end of the telescopic pipe 123 away from the dust suction pump 121 penetrates through the transparent cover 7. A dust collection cover is arranged at one end of the telescopic pipe 123 away from the dust suction pump 121. The output end of the dust suction pump 121 is fixedly communicated with a delivery pipe 124. One end of the delivery pipe 124 away from the dust suction pump 121 is communicated with the inside of the collection box 122.

[0025] The effect achieved by the entire Embodiment 2 is that by providing a clamping mechanism 2, the workpiece is placed on the operation platform 1, and the first driving motor 206 is started, causing the first driving motor 206 to drive the bidirectional threaded rod 204 to rotate. Since the second fixing rod 202 limits the clamping plate 205, the bidirectional threaded rod 204 drives the two clamping plates 205 to move relatively, facilitating the clamping and fixing of the workpiece and facilitating subsequent processing. Then, by providing a drilling mechanism 6, the second driving motor 601 is started, causing the second driving motor 601 to drive the drill bit 602 to rotate. At the same time, by starting the electric push rod 4, the fixing plate 5 drives the second driving motor 601 and the drill bit 602 to move downward, facilitating the drilling of the workpiece. Further, by providing a chip suction mechanism 12, during the drilling operation of the workpiece, a certain amount of chips will be generated. By starting the dust suction pump 121, the dust collection cover sucks the chips generated during the operation into the telescopic tube 123 and transports them to the collection box 122 through the delivery tube 124, facilitating the collection of the chips generated during the drilling operation and facilitating subsequent unified treatment.

[0026] Working principle: During use, the workpiece is placed on the operation platform 1. Subsequently, the first driving motor 206 is started, causing the first driving motor 206 to drive the bidirectional threaded rod 204 to rotate. Since the second fixing rod 202 limits the clamping plate 205, the bidirectional threaded rod 204 drives the two clamping plates 205 to move relatively to clamp and fix the workpiece. Then, the electric push rod 4 and the second driving motor 601 are started, causing the second driving motor 601 to drive the drill bit 602 to rotate. At the same time, the electric push rod 4 drives the fixing plate 5 to move downward, and the fixing plate 5 drives the rotating drill bit 602 to move downward, enabling the drill bit 602 to perform a drilling operation on the workpiece. And when the fixing plate 5 moves downward, the fixing plate 5 drives the transparent cover 7 to move downward, and the transparent cover 7 first contacts the operation platform 1, causing the transparent cover 7 to cover the periphery of the workpiece. And as the drilling mechanism 6 moves downward, the moving block 10 moves on the first fixing rod 9 and compresses the return spring 11, causing the transparent cover 7 to maintain close contact with the operation platform 1 through the elastic force of the return spring 11, preventing the phenomenon of chip splashing during the drilling of the workpiece and avoiding harm to the staff. At the same time, by starting the dust suction pump 121, the dust collection cover sucks the chips generated during the operation into the telescopic tube 123 and transports them to the collection box 122 through the delivery tube 124 to collect the chips generated during the drilling operation and facilitate subsequent unified treatment.

[0027] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
