Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment for flange processing, in particular to a quick combined clamping device. Background Art

[0002] Flange, also known as flange flange or flange, needs to be fixed with a clamping device during flange processing to facilitate precise processing. The clamping device is a device used to fix the processing object during the mechanical manufacturing process.

[0003] The existing clamping device for flange processing is generally composed of a driving mechanism and a clamping block. When the flange is clamped and fixed, the driving mechanism drives multiple clamping blocks to move closer to each other until multiple clamping blocks are in contact with the outer wall of the flange, so that the flange can be clamped and fixed.

[0004] The existing clamping device for flange processing cannot control the size of the clamping force on the flange, which may easily cause the clamping force on the flange to be too small or too large. Too small a clamping force will lead to poor clamping and fixing effect of the flange, which may easily cause the flange to fall off. Too large a clamping force will cause the flange to be subjected to excessive clamping force, which may easily cause damage to the flange. Therefore, a quick combination clamping device is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes a quick combined clamping device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a quick combined clamping device described in the utility model comprises a base; support columns are welded on the four corners of the bottom of the base, a turntable is rotatably installed on the base through a bearing seat, and a fixed plate is fixedly connected to the turntable, and the fixed plate is provided with three T-slots, and T-shaped sliders are slidably installed in the three T-slots, and an arc-shaped clamping block is fixedly connected to the top of each T-shaped slider, and an installation groove is provided in each arc-shaped clamping block, and an arc-shaped resistance block is slidably installed in each installation groove. Two springs are fixedly connected between the arc-shaped resistance block and the inner wall of the installation groove, a first electrode sheet is fixedly connected to the inner wall of the installation groove, and a second electrode sheet is fixedly connected to the side wall of the arc-shaped resistance block, and three fixed seats are fixedly connected to the turntable, and a pneumatic cylinder is installed on each fixed seat, and the action end of each pneumatic cylinder is equipped with a pneumatic rod The end of each pneumatic rod is fixed to the T-shaped slider. When the flange is clamped and fixed, the flange to be processed is placed on the fixed plate, and the pneumatic cylinder is started to make the pneumatic rod push the T-shaped slider to move, thereby driving the three arc-shaped clamping blocks to move closer to each other, and the three arc-shaped contact blocks also move closer to each other until the three arc-shaped contact blocks all contact the outer wall of the flange. The spring will be compressed by force, thereby causing the arc-shaped contact block to drive the second electrode sheet to move closer to the first electrode sheet. When the second electrode sheet contacts the first electrode sheet, the indicator light turns on, thereby promptly reminding the operator to stop the pneumatic cylinder, thereby effectively clamping and fixing the flange, and accurately controlling the clamping force of the arc-shaped contact block on the flange. While ensuring the clamping effect of the flange, it can also avoid damage to the flange, which is convenient for subsequent precise positioning processing of the flange.

[0007] Preferably, an indicator light is installed on the turntable, and the indicator light is arranged next to the fixed plate. The indicator light, the first electrode sheet and the second electrode sheet are electrically connected. When the flange is clamped and fixed, the indicator light, the first electrode sheet and the second electrode sheet cooperate with each other to promptly remind the operator to stop the operation of the pneumatic cylinder, thereby accurately controlling the clamping force of the arc-shaped resistance block on the flange, avoiding the occurrence of too small or too large clamping force on the flange.

[0008] Preferably, a driven gear ring is mounted on the outer circumferential surface of the bearing seat, and the driven gear ring is arranged between the base and the turntable, an electric motor is installed at the bottom of the base, the output and end of the motor are connected with a rotating shaft, and the top of the rotating shaft is arranged through the base, and a driving gear is mounted on the top of the rotating shaft, and the driving gear and the driven gear ring are meshed with each other. After the flange is clamped and fixed, when the flange is processed, the motor is started to make the driving gear drive the driven gear ring to mesh and rotate, thereby driving the clamped flange to rotate, so that the flange can be processed at different positions through one clamping, thereby greatly improving the processing efficiency.

[0009] The utility model is beneficial in that:

[0010] 1. When the flange is clamped and fixed, the flange to be processed is placed on the fixed plate, and the pneumatic cylinder is started, so that the pneumatic rod drives the three arc-shaped clamping blocks to move closer to each other, and the three arc-shaped contact blocks also move closer to each other until the three arc-shaped contact blocks all contact the outer wall of the flange. The spring will be compressed by force, and then the arc-shaped contact block drives the second electrode sheet to move closer to the first electrode sheet. When the second electrode sheet contacts the first electrode sheet, the indicator light turns on, so that the operator can be reminded to stop the pneumatic cylinder in time, so that the flange can be effectively clamped and fixed, and the clamping force of the arc-shaped contact block on the flange can be accurately controlled. While ensuring the clamping effect of the flange, it can also avoid damage to the flange, which is convenient for subsequent precise position processing of the flange;

[0011] 2. After the flange of the utility model is clamped and fixed, when the flange is processed, the motor is started to make the driving gear drive the driven gear ring to mesh and rotate, thereby driving the clamped flange to rotate, so that the flange can be processed at different positions through one clamping, thereby greatly improving the processing efficiency.

[0021] See also Figure 5 As shown, a driven gear ring 17 is mounted on the outer circumferential surface of the bearing seat, and the driven gear ring 17 is arranged between the base 1 and the turntable 3.

[0022] Working principle: Since the existing clamping device for flange processing cannot control the size of the clamping force on the flange, it is easy to cause the clamping force on the flange to be too small or too large.

When the second electrode sheet 12 contacts the first electrode sheet 11, the indicator light 16 becomes bright, so that the operator can be reminded in time to stop the operation of the pneumatic cylinder 14, so that the flange can be effectively clamped and fixed, and the clamping force of the arc-shaped contact block 10 on the flange can be accurately controlled. While ensuring the clamping effect of the flange, it can also avoid damage to the flange, which is convenient for subsequent precise position processing of the flange; after the flange is clamped and fixed, when the flange is processed, the motor 18 is started, so that the rotating shaft drives the driving gear 19 to rotate, and then the driven gear ring 17 also meshes and rotates, so that the clamped flange can be driven to rotate, so that the flange can be processed at different positions through one clamping, thereby greatly improving the processing efficiency.
