Description

Technical Field

[0001] The utility model relates to the technical field of bellows processing, in particular to a bellows port processing device. Background Art

[0002] Metal bellows is a kind of pipe with regular wave-like appearance. Commonly used metal bellows are carbon steel, stainless steel, steel lined with plastic, aluminum, etc. It is mainly used for non-concentric axial transmission with a very small bending radius, or irregular turning, expansion, or absorbing thermal deformation of pipes, or for connecting pipes to pipes or pipes to equipment in occasions where it is not convenient to install with fixed elbows.

[0003] After cutting, the ends of metal bellows often have burrs or irregular cutting, so the ends need to be optimized. Currently, manual polishing is mainly adopted. However, manual processing of the ends of metal bellows is prone to uneven ends, and the bellows are not positioned, which makes the processing very troublesome and affects the processing efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a bellows port processing device to solve the problems raised in the above background technology in view of the defects of the prior art.

[0005] A bellows port processing device comprises a support, a lifting mechanism installed on the support and a grinding mechanism installed on the lifting mechanism. A positioning mechanism is also correspondingly arranged below the grinding mechanism. The positioning mechanism comprises a limit seat, a limit plate, an outer cylinder, a fixed cylinder, a rotating shaft, a latch and a limit end. The limit plates are arranged in multiple groups and slide along a groove provided on the limit seat and can be locked by a locking bolt. The outer cylinder is fixedly installed in the middle of the limit seat. The fixed cylinder and the rotating shaft are both arranged on the inner side of the outer cylinder, and the fixed cylinder is rotated on the limit seat by the rotating shaft, and the fixed cylinder and the rotating shaft are limited in movement by inserting a latch. The limit end is arranged in multiple groups and distributed around the outer cylinder, and is hinged to the annular groove of the rotating shaft by a connecting arm.

[0006] By adopting the above technical solution, it is convenient to place and position the bellows.

[0007] The middle part of the upper end of the limit seat is arranged in a truncated cone-shaped structure, and the center point of the outer cylinder and the center point of the limit seat are on the same vertical line.

[0008] By adopting the above technical solution, it is convenient to put down the bellows vertically.

[0009] A plurality of annular grooves are provided on the rotating shaft from top to bottom, and at each annular groove at least three limiting ends are hingedly connected via a connecting arm.

[0010] By adopting the above technical solution, it is convenient to control the limiting end to position the bellows from the inside.

[0011] A clamping block is detachably mounted on the end of the limiting end.

[0012] By adopting the above technical solution, the bellows can be positioned by replacing the clamping block with a suitable length according to the diameter of the bellows.

[0013] A plurality of holes are formed around the edge of the rotating shaft, and a plurality of notches are also formed at the end of the fixed tube rotatably connected to the rotating shaft, so that the pin can pass through the holes and the notches on the fixed tube, thereby limiting the rotation of the rotating shaft on the fixed tube.

[0014] By adopting the above technical solution, the bellows can be locked after being positioned.

[0015] The beneficial effects of the bellows port processing device of the utility model are:

[0016] The bellows is placed vertically on the limit seat by setting, and the limit plate on the limit seat is pushed toward the bottom of the bellows. After the limit plate contacts the bottom of the bellows, the locking bolt can be rotated to lock the limit plate on the limit seat. When the rotating shaft rotates, the limit end will be pushed to move in the centrifugal direction through the latch, thereby expanding the range of multiple groups of limit ends at the same level on the outside of the outer cylinder, and limiting the inner wall of the bellows through the block, and then the latch is inserted into the hole groove and pushed downward to be inserted into the corresponding notch on the fixed cylinder, so that the rotating shaft and the fixed cylinder no longer rotate, thereby stably positioning the bellows. The device is convenient for the subsequent direct placement of the bellows, limits the bottom end of the bellows, and is suitable for positioning bellows of various sizes.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

The positioning mechanism 4 includes a limit seat 401, a limit plate 402, an outer cylinder 404, a fixed cylinder 405, a rotating shaft 406, a latch 407 and a limit end 408. The limit plate 402 is arranged in multiple groups and slides along a notch 4011 provided on the limit seat 401, and can The outer cylinder 404 is fixedly mounted in the middle of the limiting seat 401 by means of a locking bolt 403, the fixed cylinder 405 and the rotating shaft 406 are both arranged on the inner side of the outer cylinder 404, and the fixed cylinder 405 is rotated on the limiting seat 401 by means of the rotating shaft 406, and the fixed cylinder 405 and the rotating shaft 406 are limited in movement by means of a plug 407 inserted therebetween, the limiting ends 408 are multiple groups of groups distributed around the outer cylinder 404, and are hinged and movable at the annular groove of the rotating shaft 406 by means of a connecting arm 410;

[0023] The bellows is placed vertically on the limit seat 401. At this time, the limit plate 402 on the limit seat 401 is pushed close to the bottom of the bellows. After the limit plate 402 contacts the bottom of the bellows, the locking bolt 403 can be rotated to lock the limit plate 402 on the limit seat 401. (This operation is convenient for directly placing the bellows later and limiting the bottom end of the bellows so that the bellows is in a vertical state). Then the rotating shaft 406 can be rotated. When the rotating shaft 406 rotates, it will push the limit end 408 to do centrifugal rotation through the latch 407. The plurality of limit ends 408 on the same level extending out of the outer cylinder 404 are expanded, and the inner wall of the bellows is limited by the clamping block 409. Then, the latch 407 is inserted into the hole 4061 and pushed downward to be inserted into the corresponding notch on the fixed cylinder 405, so that the rotating shaft 406 and the fixed cylinder 405 no longer rotate, thereby stably positioning the bellows. At this time, the lifting mechanism 2 can be driven to push the grinding mechanism 3 to move downward, and the end surface of the bellows can be processed by the grinding wheel at the output end of the grinding mechanism 3.

[0024] The lifting mechanism 2 includes an electric push rod, a slide rail, and a slide seat. The electric push rod can be driven to push the slide seat to move up and down along the slide rail, and then the slide seat can drive the grinding mechanism 3 to move up and down, and the end surface of the corrugated pipe is processed by the grinding mechanism 3.

[0025] The middle part of the upper end of the limit seat 401 is a truncated cone-shaped structure, and the center point of the outer cylinder 404 is on the same vertical line as the center point of the limit seat 401; the outer cylinder 404 is arranged in the middle position of the limit seat 401, and after the bellows is sleeved on the outside of the outer cylinder 404, it is convenient to make centrifugal movement through the limit end 408 to limit it from the inside of the bellows, and the limit plate 402 limits the outside of its bottom.

[0026] A plurality of annular grooves are provided on the rotating shaft 406 from top to bottom, and at each annular groove, at least three limit ends 408 are hingedly connected through a connecting arm 410; a plurality of notches are provided on the outer cylinder 404 for the limit ends 408 to pass through, and when the rotating shaft 406 is rotated, the limit ends 408 can be pushed to move centrifugally through the connecting arm 410, and the limit ends 408 are positioned from the inner wall of the bellows through the block 409 at the end thereof.

[0027] A detachable clamping block 409 is provided at the end of the limiting end 408; the clamping block 409 of a suitable length can be selected according to the diameter of the bellows, and the clamping block 409 is sleeved and clamped at the end of the limiting end 408. After the limiting end 408 performs centrifugal movement, the clamping block 409 can be abutted against the inner wall of the bellows to limit the position.

[0028] A plurality of holes 4061 are formed around the edge of the rotating shaft 406, and a plurality of notches are also formed at the end of the fixed cylinder 405 where the rotating shaft 406 is rotatably connected, so that the latch 407 can pass through the holes 4061 and the notches on the fixed cylinder 405, thereby limiting the rotation of the rotating shaft 406 on the fixed cylinder 405;

[0029] After the rotating shaft 406 is rotated, the latch 407 can be inserted into the hole 4061 and pushed downward until the latch 407 is inserted into the notch of the fixed tube 405 , and the latch 407 can limit the rotating shaft 406 from rotating on the fixed tube 405 .

[0030] Working principle: Place the bellows vertically on the limit seat 401, and at this time push the limit plate 402 on the limit seat 401 to move closer to the bottom of the bellows. After the limit plate 402 contacts the bottom of the bellows, the locking bolt 403 can be rotated to lock the limit plate 402 on the limit seat 401. (This operation is convenient for the subsequent direct placement of the bellows, and the bottom end of the bellows is limited so that the bellows is in a vertical state). Then the rotating shaft 406 can be rotated. When the rotating shaft 406 rotates, the limit end 408 will be pushed to move in the centrifugal direction through the latch 407, thereby expanding the range of the multiple groups of limit ends 408 at the same level on the outside of the outer cylinder 404, and limiting the inner wall of the bellows through the block 409. Then, the latch 407 is inserted into the hole groove 4061 and pushed downward to the corresponding notch on the fixed cylinder 405, so that the rotating shaft 406 and the fixed cylinder 405 no longer rotate, thereby stably positioning the bellows.

[0031] At this time, the lifting mechanism 2 can be driven to push the grinding mechanism 3 to move downward, and the end surface of the corrugated tube is processed by the grinding wheel at the output end of the grinding mechanism 3.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
