Description

Technical Field

[0001] The invention relates to the technical field of flange processing, in particular to a novel linkage locking flange processing tool. Background Art

[0002] In the field of flange processing, it is crucial to ensure the position stability and accuracy of the flange during the processing. Traditional flange processing tools usually adopt a single clamping method, such as directly driving the clamping arm through a cylinder to clamp the outer wall of the flange. Although this clamping method can meet basic processing requirements to a certain extent, it is often difficult to ensure its stability and accuracy when facing high-precision and high-demand processing tasks;

[0003] In the prior art, a common flange processing tooling design is to drive the clamping mechanism to clamp the flange by extending and retracting the cylinder. However, this design has obvious defects. First, a single clamping method often cannot achieve uniform and precise clamping of the flange, and the uneven distribution of the clamping force can easily cause the flange to be displaced or deformed during the processing, thereby affecting the processing accuracy and product quality. Secondly, the traditional tooling design often lacks effective support and fixation for the inner wall of the flange when clamping the flange, which makes the flange susceptible to vibration or external force during the processing, further exacerbating the risk of displacement and deformation.

[0008] As a further preferred embodiment of the present technical solution, a movable groove is provided on one side of the fixed disk, a connecting block is slidably connected in the movable groove, the inner end of the connecting block is fixedly connected to the adjusting disk, and the outer end of the connecting block is provided with a cylinder installed on the top of the support seat.

[0009] As a further preferred embodiment of the present technical solution, a fixing rod is fixedly connected to the inner wall of the rectangular groove, a rectangular plate is slidably connected to the fixing rod, a third damping spring is arranged on the outer side of the rectangular plate and is sleeved on the fixing rod, a clamping block and an inclined plate are respectively fixedly connected on both sides of the top of the rectangular plate, and the positions of the clamping block and the clamping rod correspond to each other.

[0010] As a further preference of the present technical solution, a moving rod is slidably connected to the support seat, a movable disk is fixedly connected to the bottom of the moving rod, a plurality of guide rods are fixedly connected to the surface of the movable disk in a circular array, and the top of the guide rod slides in fit with the bottom of the arc pressure plate, a tension spring is arranged between the support seat and the movable disk, the tension spring is used to pull the movable disk upward so that the top of the guide rod always maintains a state of sliding in fit with the bottom of the arc pressure plate, and a plurality of trapezoidal plates corresponding to the positions of the inclined plates are arranged in a circular array on the top of the moving rod.

[0011] As a further preferred embodiment of the present technical solution, a vertical rod is fixedly connected to the top of the inner cavity of the rectangular plate, a telescopic rod is slidably connected to the top of the vertical rod, a first damping spring mounted on the vertical rod is arranged at the bottom of the telescopic rod, a pressure rod is slidably connected to the top of the telescopic rod, a cross rod is fixedly connected to the bottom of the pressure rod, and the top of the telescopic rod is slidably installed on the cross rod, and a second damping spring mounted on the cross rod is arranged on the inner side of the telescopic rod, a sliding groove is opened on the surface of the trapezoidal plate, and the telescopic rod is slidably installed in the sliding groove.

This design can clamp the outer wall of the flange evenly and accurately, ensuring the position stability of the flange during processing, thereby improving the processing accuracy; while the clamping rod moves inward according to the designed arc trajectory to clamp the outer wall of the flange, the rotation of the arc block also pushes the clamping block to move outward through a series of linkage components to clamp the inner wall of the flange. This double clamping method greatly enhances the stability of the flange during processing and effectively prevents flange displacement or deformation caused by vibration or external force.

[0016] By lowering the lifting rod and rotating the arc rod, double pressing of the flange is achieved, that is, the flange is pressed in both the vertical and horizontal directions. This double pressing can better fix the flange on the support seat to prevent displacement or loosening during processing; the stable fixing effect helps to maintain the position accuracy of the flange during processing, thereby improving processing accuracy and product quality. At the same time, double clamping and pressing reduces the risk of safety accidents caused by flange falling off or displacement, and improves the safety of the processing process.

The movable plate 36 is slidably installed between the fixed disk 31 and the top disk 32, and the top of the other end of the movable plate 36 is fixedly connected with a clamping rod 37 for clamping and positioning the outer wall of the flange. Since the positions of the fixed disk 31 and the top disk 32 are fixed, when the adjusting disk 33 rotates, the adjusting disk 33 cooperates with the second arc groove 34 to drive the arc block 35 to slide inward or outward on the fixed disk 31, thereby making the arc block 35 drive the movable plate 36 and the clamping rod 37 to move inward or outward. When it is necessary to clamp and position the flange, the movable plate 36 and the clamping rod 37 are controlled to move inward so that the clamping rod 37 clamps and fixes the outer wall of the flange.

[0031] The surface of the top plate 32 is provided with a plurality of first straight grooves 336 and second straight grooves 337 arranged in a circumferential array. The top of the connecting rod is slidably installed in the first straight groove 336, and the clamping rod 37 is slidably installed in the second straight groove 337. The first straight grooves 336 and the second straight grooves 337 are used to ensure the movement trajectory of the moving plate 36 and the clamping rod 37, so as to ensure the stability of the clamping rod 37 in clamping and fixing the outer wall of the flange when the moving plate 36 and the clamping rod 37 move inward.

[0032] A movable groove 39 is provided on one side of the fixed disk 31, and a connecting block 310 is slidably connected in the movable groove 39. The inner end of the connecting block 310 is fixedly connected to the adjusting disk 33, and the outer end of the connecting block 310 is provided with a cylinder 311 installed on the top of the support seat 1. By turning on the cylinder 311, the connecting block 310 can be driven to move in the movable groove 39, so that the connecting block 310 drives the adjusting disk 33 to rotate in the fixed disk 31 and the top disk 32, so that the adjusting disk 33 drives the arc block 35 to move, thereby adjusting the position of the movable plate 36 and the clamping rod 37;

[0033] A fixing rod 334 is fixedly connected to the inner wall of the rectangular groove 12, and a rectangular plate 318 is slidably connected to the fixing rod 334. A third damping spring 335 sleeved on the fixing rod 334 is arranged on the outer side of the rectangular plate 318. A clamping block 319 and an inclined plate 320 are fixedly connected to the top two sides of the rectangular plate 318, respectively, and the positions of the clamping block 319 and the clamping rod 37 correspond to each other. The rectangular plate 318 is slidably installed in the rectangular groove 12. When the rectangular plate 318 is controlled to slide outward on the fixing rod 334 and compress the third damping spring 335, the fixing rod 334 can drive the clamping block 319 to move outward, so that the clamping block 319 can clamp and fix the inner wall of the flange.

[0034] The support seat 1 is slidably connected with a moving rod 312, and a column 329 is fixedly connected to the top of the moving rod 312. The column 329 is used to install the flange between the clamping rod 37 and the block 319 for subsequent processing. The bottom of the moving rod 312 is fixedly connected with a movable disk 315. The surface of the movable disk 315 is fixedly connected with a plurality of guide rods 317 in a circular array, and the top of the guide rod 317 is fitted and slid with the bottom of the arc-shaped pressure plate 38. A tension spring 316 sleeved on the moving rod 312 is provided between the support seat 1 and the movable disk 315. The tension spring 316 is used to pull the movable disk 315 to move upward, so that the top of the guide rod 317 always keeps contact with the bottom of the arc-shaped pressure plate 38 The movable plate 318 is in a state of sliding fit, and a plurality of trapezoidal plates 313 corresponding to the positions of the inclined plates 320 are arranged in a circular array on the top of the movable rod 312. The inclined surfaces of the trapezoidal plates 313 slide fit with the inclined surfaces of the inclined plates 320. When the arc block 35 rotates with the arc pressure plate 38, it can push the guide rod 317 and the movable disk 315 to move downward, so that the movable disk 315 drives the movable rod 312 to move downward and stretch the rectangular plate 318. When the movable rod 312 moves downward, it drives the trapezoidal plate 313 to move downward, so that the trapezoidal plate 313 pushes the inclined plate 320, the rectangular plate 318, and the clamping block 319 to move outward, so that the clamping block 319 clamps the inner wall of the flange.

[0035] A vertical rod 321 is fixedly connected to the top of the inner cavity of the rectangular plate 318, and a telescopic rod 322 is slidably connected to the top of the vertical rod 321. A first damping spring 323 sleeved on the vertical rod 321 is provided at the bottom of the telescopic rod 322. A pressure rod 338 is slidably connected to the top of the telescopic rod 322, and a cross bar 324 is fixedly connected to the bottom of the pressure rod 338. The top of the telescopic rod 322 is slidably installed on the cross bar 324, and a second damping spring 325 sleeved on the cross bar 324 is provided on the inner side of the telescopic rod 322. A sliding groove 314 is opened on the surface of the trapezoidal plate 313, and the telescopic rod 322 is slidably installed in the sliding groove 314. When the rectangular plate 318 moves outward, it can drive the telescopic rod 322 to move synchronously. The telescopic rod 322 is slidably installed on the top of the rectangular plate 318 in the vertical direction.

[0036] The movable rod 312 is provided with a lifting rod 326, which can be located on the moving rod 312 to move up and down and rotate at the same time, and the bottom of the lifting rod 326 is threadedly connected to the support seat 1, and the top of the lifting rod 326 is provided with a plurality of arc rods 327 corresponding to the positions of the pressure rod 338 in a circular array, and the outer end of the arc rod 327 slides in contact with the inner end of the pressure rod 338, and the top of the arc rod 327 is fixedly connected to the limit plate 328, and the limit plate 328 is located above the pressure rod 338, and the bottom of the lifting rod 326 is connected to the sleeve rod 330 through a spline rod, and the sleeve rod 330 is rotatably installed at the bottom of the support seat 1, and a driving motor 333 is installed on the support seat 1, and the output end of the driving motor 333 is fixedly connected to the transmission rod 332, and the other end of the transmission rod 332 is transmission-connected to the sleeve rod 330 through a bevel gear set 331, and the transmission rod 332 is driven forward or reversed by turning on the driving motor 333 When the lifting rod 326 drives the arc rod 327 and the limit plate 328 to move downward, the limit plate 328 is located at the top of the pressure rod 338, that is, when the limit plate 328 moves downward, the pressure rod 338 and the telescopic rod 322 are driven to move downward and compress the first damping spring 323. At the same time, when the lifting rod 326 rotates, the arc rod 327 is driven to rotate, so that the arc rod 327 can push the pressure rod 338 to move outward and compress the second damping spring 325 when rotating, so that the pressure rod 338 moves toward the top of the flange, so that the pressure rod 338 can press the top of the flange downward, so as to better fix the flange on the support seat 1, thereby facilitating the subsequent flange processing.

[0037] In the embodiment of the present invention, by turning on the cylinder 311, the connecting block 310 can be driven to move linearly in the moving groove 39 through the telescopic action of the cylinder 311. The movement of the connecting block 310 drives the adjusting disk 33 to rotate between the fixed disk 31 and the top disk 32. The rotation action of the adjusting disk 33 further causes the arc block 35 to move along its designed arc trajectory. As the arc block 35 moves, it drives the moving plate 36 and the clamping rod 37 to move inward, thereby clamping and fixing the outer wall of the flange. Since the clamping rod 37 moves inward according to the designed arc trajectory, it can The outer wall of the flange can be clamped evenly and accurately. This accurate clamping helps to ensure the position stability of the flange during the processing, thereby improving the processing accuracy. The clamping rod 37 moves inward to achieve a tight clamping of the outer wall of the flange, effectively preventing the flange from moving or deforming during the processing. This stability is crucial to ensuring the processing quality and avoiding damage to the workpiece. In addition, this clamping method is suitable for flanges of different sizes and shapes. By adjusting the telescopic degree of the cylinder 311 and the design of the arc block 35, the clamping and fixing of flanges of different specifications can be achieved, thereby improving the versatility and flexibility of the equipment.

[0038] At the same time, as the arc block 35 rotates with the arc pressure plate 38, the guide rod 317 and the movable plate 315 are pushed downward. The downward movement of the movable plate 315 drives the moving rod 312 to move downward and stretches the rectangular plate 318. The descent of the moving rod 312 simultaneously drives the trapezoidal plate 313 to move downward. The movement of the trapezoidal plate 313 drives the inclined plate 320 and the rectangular plate 318 to move outward. The rectangular plate 318 slides outward on the fixed rod 334, compressing the third damping spring 335 to absorb and buffer the impact force during the movement. The movement of the fixed rod 334 drives the clamping block 319 to move outward. The clamping block 319 can clamp and fix the inner wall of the flange, thereby realizing double clamping of the flange, ensuring the stability and accuracy of the flange during the processing. Through the rotation of the arc block 35 and the linkage of the moving rod 312, the trapezoidal plate 313 and other components, the method The flange is not only fixed by the outer wall clamping device, but also clamped by the inner wall through the clamping block 319. This double clamping method greatly enhances the stability of the flange during the processing, and effectively prevents the displacement or deformation of the flange caused by vibration or external force. The double clamping ensures the precise positioning of the flange during the processing. Both the outer wall and the inner wall are firmly fixed, which helps to maintain the geometric shape and dimensional accuracy of the flange, thereby improving the processing quality and product consistency. Compared with a single clamping method, the double clamping provides a greater clamping force. This increased clamping force can better resist the cutting force and other forces generated during the processing, ensuring that the flange will not be damaged or fall off during the processing. The double clamping ensures that the flange is firmly fixed during the processing, reducing the risk of safety accidents caused by the flange falling off or displacement, which helps to improve the safety of the processing process.

[0039] In addition, by turning on the drive motor 333, the rotation of the motor is transmitted through the transmission rod 332, and the transmission rod 332 drives the sleeve rod 330 to rotate through the bevel gear set 331. The sleeve rod 330 cooperates with the spline rod to drive the lifting rod 326 to move downward and rotate on the support seat 1. The downward movement of the lifting rod 326 drives the arc rod 327 and the limit plate 328 to move downward. Since the limit plate 328 is located at the top of the pressure rod 338, the downward movement of the limit plate 328 drives the pressure rod 338 and the telescopic rod 322 to move downward and compress the first damping spring 323 to absorb and buffer the impact force during the descent. At the same time, during the rotation of the lifting rod 326, the rotation of the arc rod 327 pushes the pressure rod 338 to move outward and compresses the second damping spring 325, so that the pressure rod 338 moves toward the top of the flange to achieve downward pressing of the top of the flange. Through this double pressing action, the flange can be better fixed on the support seat 1, so as to facilitate the subsequent flange processing. The double pressing action not only presses the flange in the vertical direction by the descent of the lifting rod 326, but also pushes the pressing rod 338 to move outward through the rotation of the arc rod 327 to press the top of the flange in the horizontal direction. This double pressing can better fix the flange on the support seat 1 to prevent displacement or loosening due to vibration or external force during the processing. The stable fixing effect helps to maintain the position accuracy of the flange during the processing. Through double pressing, it can be ensured that the flange always maintains the correct position and posture during the processing, thereby improving the processing accuracy and product quality.

[0040] In summary, the device of the present invention realizes rapid and accurate clamping and positioning of the flange through the precise coordination and coordinated operation of multiple components, thereby greatly improving the efficiency and accuracy of flange processing.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
