Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, and particularly relates to an automobile flange processing device. Background Art

[0002] The flange is a component used for connecting between shafts or pipe ends. It is usually in a ring structure and is widely used in fields such as petrochemical industry, power system, shipbuilding, metallurgy, aerospace, and vehicle engineering. The quality of the flange directly affects the sealing performance and stability performance of the system, etc. During the processing and manufacturing of the flange, it is usually necessary to drill holes in the forged and formed ring flange blank parts to facilitate the installation and connection of the flange. The Chinese patent document CN220128214U discloses a drilling device for the production of butt-welding flanges. When drilling the butt-welding flange, different-sized butt-welding flanges are first placed on the support ring, and then the bidirectional threaded rod is rotated to make the two moving blocks move from the outside to the inside, thereby driving the two clamping frames to clamp different-sized butt-welding flanges. Then, a drill bit is used for drilling. After drilling, the connection column is rotated to change the orientation of the butt-welding flange and continue drilling, which is beneficial to improving the convenience and practicality of the device for drilling. At the same time, by setting the limit disk, the card slot, the circular groove, and the first limit column, when the connection column drives the limit disk to rotate, the positions of the circular groove and the card slot correspond to each other, and then the first limit column is used to limit it, which is beneficial to improving the stability of the limit disk and preventing the connection column from rotating during the drilling process, thereby affecting the drilling effect of the butt-welding flange. However, this drilling device lacks an automatic centering device, resulting in the center of the flange being misaligned (i.e., not collinear) with the center of the drilling device during the clamping or drilling process of the clamping frame, and there is an offset, thus resulting in the problem that the drilled holes are not evenly distributed on the flange, affecting subsequent installation or connection. At the same time, due to the downward impact force of the drilling device, some flanges with a relatively thin thickness are easily affected by the instantaneous impact force during the drilling process and warp or deform. This drilling device lacks an effective limiting mechanism, thus easily affecting the drilling quality and increasing the unqualified rate of the prepared products. Summary of the Utility Model

[0003] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide an automobile flange processing device, which can achieve automatic positioning during the drilling process of flanges with different sizes, thereby avoiding the problem of the center line offset between the flange and the drilling device. At the same time, the device can also limit the flange to prevent problems such as warping and deformation due to the downward impact force of the drilling device during the drilling process.

[0004] The purpose of the utility model is achieved through the following technical solutions:

The second screw rod is threadedly connected with the second pressing block, and the rubber block is arranged on the inner wall of the translation slider below the second pressing block.

[0006] Based on the further optimization of the above scheme, a support frame is arranged on the outer ring of the bottom surface of the support table for supporting and placing the support table on the ground.

[0007] Based on the further optimization of the above scheme, a collection groove is evenly arranged around the central axis of the through hole between the inner ring positioning component and the outer ring clamping component of the support table. One is to facilitate the drill bit to penetrate the flange and realize the preparation of the through hole, and the other is to facilitate the collection of debris after drilling.

[0008] Based on the further optimization of the above scheme, the inner ring positioning component is driven to slide on the end face of the support table through a slider mechanism.

The fixed sleeve is communicated with the through hole; The output shaft of the first motor is fixedly provided with a lifting screw rod, and the lifting screw rod is coaxial with the through hole; The conical slider is slidably arranged in the fixed sleeve, and the top of the conical slider is a conical structure with a small upper diameter and a large lower diameter. The inclined surfaces of the conical slider are respectively provided with pushing connecting rods corresponding to the arc-shaped slider. One end of the pushing connecting rod is slidably connected with the inclined surface of the conical slider, and the other end is fixedly connected with the inner wall of the arc-shaped slider (that is, the side surface of the arc-shaped slider close to the through hole).

[0009] Based on the further optimization of the above scheme, a rubber layer is arranged on the outer wall of the arc-shaped slider below the first pressing block.

[0010] Based on further optimization of the above solution, the outer clamping assembly is driven by a turntable mechanism to slide on the end face of the support table. The turntable mechanism includes a rotating disk, a synchronous connecting rod, a second motor, a transmission rod, and a driving gear. The rotating disk is coaxially arranged with the fixed sleeve, and the rotating disk is rotatably sleeved on the outer wall of the fixed sleeve. The support table is provided with a horizontal chute corresponding to the translation slider, and the rotating disk is provided with an arc chute corresponding to the parallel slider. The bottom of the translation slider is fixedly provided with a synchronous connecting rod.

An external toothed ring is fixedly provided on the outer wall of the rotating disk. A second motor is fixedly provided on one end face of the support table. A transmission rod is fixedly provided on the output shaft of the second motor. The transmission rod penetrates through the support table, and a driving gear is fixedly sleeved on the outer wall of the transmission rod corresponding to the rotating disk.

At the same time, through the outward expansion of the arc-shaped slider, it ensures the coaxiality of the central axis between the flange and the support table, that is, realizes the central positioning of the flange placed on the end face of the support table, and avoids the problem of uneven punching caused by the deviation of the flange center due to external force during the punching process. The outer ring clamping assembly composed of a translation slider, a second screw rod, a second pressing block, and a rubber block realizes the outer ring clamping of the flange after central positioning, thereby ensuring the stable positioning of the flange and avoiding the deviation of the flange during the punching process. In addition, by using the extrusion of the first pressing block and the second pressing block on the end face of the flange during the positioning process, problems such as warping or deformation of the flange during the punching process are avoided, ensuring the punching quality.

In this embodiment, the number of the collecting grooves 12 is ten, and the collecting groove 12 is a key groove structure). One is to facilitate the drill bit to penetrate the flange and realize the preparation of the through hole, and the other is to facilitate the collection of debris after drilling.

[0029] Working principle:

[0030] During use, first place the flange to be processed (i.e., drilled) on the end face of the support table 10 so that the inner ring positioning component is located on the inner wall of the central hole of the flange; then, start the first motor 42, and drive the conical slider 44 to move upward by the rotation of the first screw 43, thereby driving the corresponding arc-shaped slider 21 to expand outward by pushing the connecting rod 45, realizing the inner clamping and central positioning of the flange by the arc-shaped slider 21 (i.e., ensuring that the central axis of the flange is collinear with the central axis of the through hole 11). At this time, the first pressing block 23 forms clamping extrusion on the corresponding top surface of the flange (the first screw 22 can be adjusted according to the thickness of the flange to be processed, so that the first pressing block 23 moves up and down, and further ensure that the bottom surface of the first pressing block 23 fits the end face of the flange); then, drive the driving gear 55 to rotate by the rotation of the second motor 53 and the transmission rod 54, and then realize the rotation of the rotating disk 51. The rotating disk 51 drives the synchronous connecting rod 52 to retract through the cooperation of the arc-shaped chute 510 and the horizontal chute 13, and then pulls the horizontal slider 31 to retract, and realizes the outer clamping of the flange to be processed through the rubber block 34 and the second pressing block 33 (similarly, the second screw 32 can be adjusted according to the thickness of the flange to be processed). Through the inner and outer clamping, on the one hand, the stable positioning of the flange is realized, and the offset of the flange during the processing is avoided; on the other hand, the inner and outer circles of the flange are extruded and shaped, and problems such as warping and deformation during the processing are avoided.

[0031] Embodiment 2:

[0032] As another preferred embodiment of the present application, on the basis of the solution of Embodiment 1, a drill bit structure capable of moving up and down is provided on the end face of the support table 10 and corresponding to the translation slider 31. The drill bit structure adopts the existing structure in the art (the drill bit structure in the patent document CN220128214U).
