Technical Field

[0001] The utility model belongs to the technical field of flange processing, and in particular relates to a flange end surface grinding device. Background Art

[0002] Flange is a general term for a flange. It usually refers to a disk-like metal body with several holes for fixing around it for connecting other things. The end face of the flange generally needs to be connected with other parts. In order to ensure the sealing of the connection, the end face needs to be polished and smooth.

[0003] The existing flange end face grinding usually uses claws to clamp the inner wall or outer wall of the flange, and the flange end face is processed by the grinding equipment. Since the clamping equipment is frequently used during the processing, the existing claw structure has a complex internal structure, is prone to failure during adjustment and use, and is difficult to maintain and repair, which easily affects production efficiency.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The utility model provides a flange end surface grinding device, such as Figure 1-Figure 5 As shown, the flange end surface grinding device comprises:

[0029] A side table 100, wherein a driving motor is disposed inside the side table 100, a rotating shaft 310 of the driving motor extends to the outside of the side table 100, a polishing wheel 320 is disposed at the end of the rotating shaft 310, and the polishing wheel 320 rotates under the action of the driving motor, and the friction force during the rotation process is used to complete the polishing of the workpiece surface;

[0030] The base 200 includes a bottom plate 210, a guide seat 220, and a sliding seat 230 sliding on the guide seat 220. The sliding seat 230 transfers the workpiece to the bottom of the polishing wheel 320 during the sliding process along the guide seat 220, so that the workpiece comes into contact with the polishing wheel 320;

[0031] An assembly table 400, wherein the assembly table 400 is disposed on the sliding seat 230, and a workpiece to be processed is placed on the assembly table 400, and the assembly table 400 provides support force to the workpiece to ensure that the end surface of the workpiece maintains contact with the polishing wheel 320 during the processing;

[0032] The assembly table 400 includes an inner ring plate 410, an adjusting member 440 and two groups of annular supports 430; the annular supports 430 are in contact with the adjusting member 440, and the contact surface between the annular supports 430 and the adjusting member 440 is inclined to the first plane. When the adjusting member 440 moves perpendicular to the first plane, the annular supports 430 will move away from or close to the inner ring plate 410; the inner wall of the workpiece is nested on the circumference of the inner ring plate 410, and when the annular supports 430 are away from the inner ring plate 410, the annular supports 430 will generate a resisting force on the workpiece to complete the fixed support of the workpiece;

[0033] In the present application, the structures adopted on the side table 100 are all existing mature equipment. The side table 100 mainly serves to construct a processing area perpendicular to the first plane. When the sliding seat 230 pulls the workpiece to the bottom of the processing area, the polishing wheel 320 will grind the end face of the workpiece through its circular motion.

[0034] A horizontal drive motor is provided inside the sliding seat 230, and the assembly table 400 is mounted on the motor shaft of the horizontal drive motor. During the rotation of the polishing wheel 320, the assembly table 400 rotates synchronously to ensure that different areas of the workpiece on the assembly table 400 can enter the processing area for processing; the first plane is the plane where the base 200 is located, and the polishing wheel 320 is arranged perpendicular to the first plane;

[0035] As a preferred implementation in this embodiment, the annular support 430 includes a support block 431 and a push rod 432; the support block 431 is arranged on the outer side of the inner ring plate 410, and the push rod 432 extends from a sliding opening 412 provided on the side wall of the inner ring plate 410 to the inner side of the inner ring plate 410;

[0036] The inner ring plate 410 is also provided with a guide groove 411 adapted to the push rod 432. One end of the push rod 432 away from the support block 431 extends out of the guide groove 411 and is in contact with the adjustment member 440. Here, part of the push rod 432 slides in the guide groove 411 and the sliding opening 412. The guide groove 411 and the sliding opening 412 are used to ensure the linearity of the push rod 432 during the sliding process.

[0037] The push rod 432 is also provided with a limit block 433, which abuts against the end of the guide groove 411 away from the sliding opening 412 during the sliding process, and the limit block 433 prevents the push rod 432 from slipping out of the guide groove 411 as a whole;

[0038] The adjusting member 440 includes a fixing seat 441, a push block 442 and a push bolt 443. The push bolt 443 passes through the push block 442 and is threadedly matched with the fixing seat 441. Both ends of the push block 442 are inclined structures and are respectively in contact with the push rod 432. When the distance between the push rods 432 is small, the two ends of the push block 442 will be higher than the height of the push rod 432. When the push bolt 443 is screwed in the direction of the fixing seat 441, the push block 442 will drop in height and push the push rod 432 away from the fixing seat 441. Since the push rods 432 are far away from each other, the support block 431 will apply a thrust to the inner wall of the workpiece located outside the inner ring plate 410, thereby improving the overall connection strength between the workpiece and the annular support 430. The support block 431 is made of wear-resistant rubber material, which improves the limiting ability during the fixing process.

[0039] The assembly table 400 further includes a support plate 420, the inner ring plate 410 and the fixing seat 441 are both arranged on the support plate 420, an axial hole is arranged at the center of the support plate 420, and the horizontal driving motor drives the support plate 420 to rotate as a whole;

[0040] As a preferred implementation in this embodiment, the guide seat 220 is provided with a guide slot 221, and an adjusting screw 222 is arranged in the guide slot 221; the adjusting screw 222 extends out of the guide seat 220 from one end of the guide slot 221; a hand wheel is arranged at one end of the adjusting screw 222 extending out of the guide seat 220, and the adjusting screw 222 is rotated by adjusting the hand wheel;

[0041] The sliding seat 230 is provided with a guide slider 231, and the guide slider 231 is provided with a screw hole adapted to the adjusting screw 222, and the adjusting screw 222 is assembled in the screw hole;

[0042] In this embodiment, the guide slider 231 and the adjusting screw 222 adopt the same structure as the ball screw transmission technology in the prior art, the screw hole is filled with balls, and the adjusting screw 222 is equivalent to the screw structure; when the hand wheel rotates, it drives the guide slider 231 to move;
