Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a clamping mechanism and a flange punching device. Background Technique

[0002] The flange is simply called a flange, which is just a general term. Usually, it refers to a disk-shaped metal body with several fixing holes on its periphery for connecting other things. It is widely used in machinery. The flange is also called a flange plate or a flange. It is a part that connects pipes to each other and is connected to the pipe end. There are holes on the flange, and bolts are used to tightly connect the two flanges. A gasket is used for sealing between the flanges. The flange is a disk-shaped part and is the most common in pipeline engineering. Flanges are always used in pairs.

[0003] In Chinese Patent CN112775462A, this application relates to the technical field of punching equipment and relates to a punching equipment for a flange, including a base, a clamping mechanism installed on the base, and a punching mechanism located above the clamping mechanism. The clamping mechanism includes a plurality of splicable overhead blocks, a clamping block detachably connected to the upper side of the overhead block and used to press the flange against the overhead block, and a positioning component for positioning the flange. Both the overhead block and the clamping block are annularly arranged, and the overhead block is provided with a first slot for placing the flange in the vertical direction. The overhead block is connected to the clamping block through a connecting piece; through the positioning of the flange by the positioning component, the second punching position of the flange is located directly below the punching mechanism, thereby ensuring the distance accuracy between the two holes, and thus improving the yield rate of the flange.

[0004] Existing clamping mechanisms and flange punching devices have the problems that due to the variety of flange types and different sizes, the device needs to clamp according to different sizes of flanges and stick tightly to the outer wall of the flange to prevent the flange from shifting during punching, resulting in punching errors, making the flange unusable, and increasing production costs. At the same time, due to the different sizes of holes required for punching according to the needs of the flange, and the punching tool needs to be replaced frequently when used, the replacement process of the existing device is relatively cumbersome, resulting in a lack of practicality of the device during use.

[0005] Therefore, a clamping mechanism and a flange punching device are proposed for the above problems. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art, the utility model solves the problems that due to the variety of flange plates with different sizes, the device needs to clamp according to flange plates of different sizes and closely adhere to the outer wall of the flange plate to prevent the flange plate from shifting during drilling, resulting in drilling errors, rendering the flange plate unusable, increasing production costs, and at the same time, due to the different sizes of holes to be drilled according to the requirements of the flange plate and the need to replace the drill frequently during use, the process of replacement of the existing device is rather cumbersome, resulting in the lack of practicality of the device during use.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: A clamping mechanism of the utility model includes a base of a drilling device, on the top of which a flange plate clamping component is installed, and a clamping control component is connected to the side of the flange plate clamping component; the flange plate clamping component includes a motor, a worm is rotatably connected to the top of the motor, a worm gear is meshed with the side of the worm, and a transmission threaded rod is fixedly connected to the inside of the worm gear.

A flange clamping assembly 2 is installed on the top of the base 1 of the punching device, and a clamping control assembly 3 is connected to the side of the flange clamping assembly 2. The flange clamping assembly 2 includes a motor 201. A worm 202 is rotatably connected to the top of the motor 201. A worm gear 203 is meshed with the side of the worm 202. A driving threaded rod 204 is fixedly connected to the inside of the worm gear 203. A first control block 205 is threadedly connected to one side of the driving threaded rod 204, and a second control block 206 is threadedly connected to the other side of the driving threaded rod 204. The clamping control assembly 3 includes a connecting block 301. A manipulating block 302 is fixedly connected to the side of the connecting block 301. A rotating ball 303 is rotatably connected to the inside of the manipulating block 302. A rotating block 304 is fixedly connected to the side of the rotating ball 303. Both the first control block 205 and the second control block 206 form a sliding structure with the base 1 of the punching device through the driving threaded rod 204 and the worm gear 203. The worm gear 203 is meshed with the worm 202. The rotating block 304 forms a rotating structure with the manipulating block 302 through the rotating ball 303, and the rotating balls 303 are equidistantly arranged inside the manipulating block 302.

[0023] Please refer to Figure 1 And Figure 4As shown in the figure, a flange drilling device further includes a flange drill fixing component 4. The flange drill fixing component 4 includes a drill body 401. A connecting seat 402 is fixedly connected to the top of the drill body 401. A sliding groove 403 is formed on the outer wall of the connecting seat 402. The top of the connecting seat 402 is connected to a fixing seat 404. A clamping block 405 is integrally provided on the inner wall of the fixing seat 404. An elastic piece 406 is provided on the top of the clamping block 405. A spring 407 is installed on the top of the elastic piece 406. A support frame 408 is fixedly connected to the top of the fixing seat 404. An electric telescopic rod 409 is connected to the side of the support frame 408. The connecting seat 402 and the fixing seat 404 form a detachable structure through the sliding groove 403 and the clamping block 405. The elastic piece 406 and the clamping block 405 form an elastic structure through the spring 407.

[0024] Working principle: First, turn on the switch of the motor 201, so that the motor 201 drives the worm 202 to rotate. Since a worm gear 203 is engaged on the side of the worm 202, the rotating worm 202 will drive the worm gear 203 to rotate. At this time, the worm gear 203 will drive the transmission threaded rod 204 to rotate, thereby controlling the positions of the first control block 205 and the second control block 206, making the first control block 205 and the second control block 206 get closer and closer to each other. In this way, the connecting block 301 can drive the control block 302 to get closer and closer until the flange is clamped. At the same time, a rotating ball 303 and a rotating block 304 are provided on the side of the control block 302, so that the rotating block 304 on the side of the control block 302 will rotate in multiple directions through the rotating ball 303, making the rotating block 304 can closely adhere to the outer wall of the flange. Since the outer wall of the flange is circular and the rotating block 304 can rotate in multiple directions through the rotating ball 303, it can adjust the angle according to the shape of the outer wall of the flange, thus realizing the clamping of the flange.

[0025] Next, according to the need for the size of the drilled hole, select a drill body 401 of a suitable size. Bring the drill body 401 close to the fixing seat 404 through the connecting seat 402, so that the clamping block 405 in the fixing seat 404 slides into the sliding groove 403 on the side of the connecting seat 402. At this time, the elastic piece 406 will squeeze the spring 407. Then rotate the connecting seat 402, so that the clamping block 405 slides horizontally in the sliding groove 403. Then release the connecting seat 402. At this time, the clamping block 405 slides again under the elastic force of the spring 407, so that the drill body 401 is fixed. The operation is simple and convenient, and the drill body 401 can be replaced.

[0026] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model.
