Description

Technical Field

[0001] The utility model relates to the technical field of parts correction, in particular to a mechanism for correcting a deformed inner cavity circular hole. Background Art

[0002] Parts can be of various shapes and sizes, made of different materials such as metal, plastic, rubber, etc. They have different functions and uses. Some common parts include bolts, nuts, bearings, gears, etc. Parts play various roles in machines, such as transmitting power, supporting structures, controlling operations, etc.

[0003] At present, some parts are prone to deformation during use or processing, which causes the size of their inner cavity circular holes to fail to meet the needs of conventional use. Conventional means of correcting parts cannot effectively guarantee the size of the parts, and the correction efficiency is low. Therefore, it is necessary to design a mechanism for correcting deformed inner cavity circular holes to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a mechanism for correcting a deformed inner cavity circular hole, so as to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mechanism for correcting a deformed inner cavity circular hole, comprising a rotating rod and a stop block, wherein two stop blocks are provided and are located on the left side of the rotating rod, an expansion core is slidably connected to the surfaces of the two stop blocks, and grooves are provided on opposite sides of the two stop blocks, and a reciprocating screw is fixedly installed on the left end of the rotating rod;

[0006] The left end of the reciprocating screw passes through two stops and extends to the inside of the left stop. Nuts are threadedly connected on both sides of the surface of the reciprocating screw and located inside the groove. One side of the nut is fixedly connected to one side of the inner cavity of the groove. A limiting mechanism is arranged below the rotating rod.

[0007] Preferably, the limiting mechanism comprises a square rod arranged below the rotating rod, the left end of the square rod passes through two stop blocks in sequence and extends to the inside of the left stop block, and a sliding opening for use with the square rod is provided on one side of the stop block.

[0008] Preferably, a limiting plate is fixedly mounted on the left end of the square rod, and a limiting groove for use in conjunction with the limiting plate is provided on the left side of the abutment block on the left side.

[0009] Preferably, an L-shaped rod is fixedly mounted on the right end of the square rod.

[0010] Preferably, a movable opening for use with a reciprocating screw is provided on one side of the stop block.

[0011] Preferably, the surface of the expansion core is provided with grooves, and there are a plurality of grooves.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The mechanism for correcting the deformed inner cavity circular hole is implemented by extending the expansion core into the inner cavity circular hole of the deformed part, and then holding the L-shaped rod and twisting the rotary rod. At this time, the rotation of the rotary rod drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the two nuts to move toward the middle at the same time. The movement of the nuts drives the movement of the stop block. The movement of the stop block can squeeze the expansion core to expand the expansion core. The expansion of the expansion core can correct the inner cavity hole of the part, which not only ensures the size of the part after correction, but also improves the correction efficiency, greatly reducing the risk of such parts when correcting the inner cavity hole.

[0014] 2. The mechanism for correcting the deformed inner circular hole is achieved by taking the expanding core out of the inner cavity of the part, and then pulling the square rod to the left and rotating it ninety degrees. The rotation of the square rod drives the limit plate to rotate. After the limit plate rotates ninety degrees, it no longer limits the left-side stop block. At this time, the rotating rod can be rotated to drive the left-side stop block to move to the left. After the stop block moves to the left, it can be disengaged from the reciprocating screw, thereby achieving the effect of facilitating the installation and removal of the expanding core.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Please refer to Figure 1-5 As shown, the utility model provides a mechanism for correcting a deformed inner cavity circular hole, comprising a rotary rod 1 and a stopper 4, wherein two stoppers 4 are provided and are located on the left side of the rotary rod 1, and an expansion core 6 is slidably connected to the surfaces of the two stoppers 4, and a plurality of grooves are provided on the surface of the expansion core 6, and grooves 5 are provided on opposite sides of the two stoppers 4, and a reciprocating screw 2 is fixedly installed on the left end of the rotary rod 1;

[0024] Specifically, the left end of the reciprocating screw 2 passes through the two stop blocks 4 and extends to the inside of the left stop block 4. One side of the stop block 4 is provided with a movable opening 7 for use with the reciprocating screw 2. Both sides of the surface of the reciprocating screw 2 and the inside of the groove 5 are threadedly connected with nuts 3. One side of the nut 3 is fixedly connected to one side of the inner cavity of the groove 5. A limiting mechanism is provided below the rotating rod 1. The limiting mechanism includes a square rod 9 provided below the rotating rod 1. The left end of the square rod 9 passes through the two stop blocks 4 in sequence and extends to the inside of the left stop block 4. One side of the stop block 4 is provided with a movable opening 7 for use with the reciprocating screw 2. The right end of the sliding mouth 8 and the square rod 9 is fixedly installed with an L-shaped rod 12. By setting the expansion core 6, and extending the expansion core 6 into the inner circular hole of the deformed part, and then holding the L-shaped rod 12 and twisting the rotary rod 1, the rotation of the rotary rod 1 drives the reciprocating screw 2 to rotate, and the rotation of the reciprocating screw 2 drives the two nuts 3 to move toward the middle at the same time, and the movement of the nut 3 drives the stop block 4 to move. The movement of the stop block 4 can squeeze the expansion core 6 to expand the expansion core 6. The expansion of the expansion core 6 can correct the inner cavity hole of the part, which not only ensures the size of the part after correction, but also improves the correction efficiency.

[0025] Specifically, a limit plate 10 is fixedly installed on the left end of the square rod 9, and a limit groove 11 used in conjunction with the limit plate 10 is opened on the left side of the left side stop block 4. By setting the limit plate 10, the effect of limiting the left side stop block 4 can be achieved. When the expansion core 6 needs to be installed or removed, the square rod 9 can be pulled to the left, and the square rod 9 moves to the left to drive the L-shaped rod 12 to move to the left. After the L-shaped rod 12 moves to the inside of the sliding mouth 8, the L-shaped rod 12 can be rotated ninety degrees, and the rotation of the L-shaped rod 12 drives the square rod 9 to rotate, and the rotation of the square rod 9 drives the limit plate 10 is rotated, and the square rod 9 can be pulled to the right after the limit plate 10 is rotated ninety degrees. At this time, the limit plate 10 can be moved to the inside of the slide 8. After the limit plate 10 moves to the inside of the slide 8, it no longer limits the left-side stop block 4. At this time, the rotating rod 1 can be rotated to make the rotating rod 1 drive the left-side stop block 4 to move to the left. After the stop block 4 moves to the left, the left-side nut 3 can be disengaged from the reciprocating screw 2. After the left-side nut 3 is disengaged from the reciprocating screw 2, the left-side stop block 4 can be removed from the surface of the reciprocating screw 2, thereby achieving the effect of facilitating the installation and removal of the expansion core 6.

[0026] Working principle: The utility model is a mechanism for correcting a deformed inner cavity circular hole. The expansion core 6 is inserted into the inner cavity circular hole of the deformed part, and then the L-shaped rod 1 is held and the rotary rod 1 is twisted. At this time, the rotary rod 1 rotates to drive the reciprocating screw 2 to rotate, and the reciprocating screw 2 rotates to drive the two nuts 3 to move toward the middle at the same time. The movement of the nut 3 drives the stop block 4 to move. The movement of the stop block 4 can squeeze the expansion core 6 to expand the expansion core 6. The expansion of the expansion core 6 can correct the inner cavity hole of the part, which not only ensures the size of the part after correction, but also improves the correction efficiency. When the correction is completed, the expansion core 6 can be taken out from the inner cavity of the part, and then the square rod 9 can be pulled to the left. The square rod 9 moves to the left and drives the L-shaped rod 12 to move to the left. After the L-shaped rod 12 moves to the inside of the sliding mouth 8, the L-shaped rod 12 can be rotated ninety degrees. The rotation of the L-shaped rod 12 drives the square rod 9 to rotate, and the rotation of the square rod 9 drives the limit plate 10 to rotate. After the limit plate 10 is rotated ninety degrees, the square rod 9 can be pulled to the right. At this time, the limit plate 10 can be moved to the inside of the sliding mouth 8. After the limit plate 10 moves to the inside of the sliding mouth 8, it no longer limits the left-side stop block 4. At this time, the rotating rod 1 can be rotated to make the rotating rod 1 drive the left-side stop block 4 to move to the left. After the stop block 4 moves to the left, the left-side nut 3 can be disengaged from the reciprocating screw 2. After the left-side nut 3 is disengaged from the reciprocating screw 2, the left-side stop block 4 can be removed from the surface of the reciprocating screw 2, thereby achieving the effect of facilitating the installation and removal of the expansion core 6.
