Description

Technical Field

[0001] This utility model relates to the technical field of equipment related to ring forging production, specifically a ring forging eccentricity correction device. Background Technology

[0002] After the ring forging is produced, the coaxiality requirement of the ring forging is relatively high, so it is necessary to control the eccentricity of the ring forging. However, when the eccentricity of the ring forging was detected and corrected before, the limit block may pop out completely under the action of the large spring when the ring forging passes through the positioning shaft, which affects the abutment effect on the ring forging.

[0003] Document CN202020393521 discloses an eccentricity correction device for a ring forging, including a base, a positioning shaft, a drive motor, and an ultrasonic rangefinder. The drive motor is horizontally mounted on the base, and the positioning shaft is connected to the output shaft of the drive motor, allowing the drive motor to drive the positioning shaft to rotate. The outer diameter of the positioning shaft matches the inner diameter of the ring forging, allowing the ring forging to be fitted tightly onto the positioning shaft. An annular limiting protrusion is provided on the end face of the connection between the positioning shaft and the drive motor, allowing the ring forging to abut against the limiting protrusion. The ultrasonic rangefinder is mounted on the base, positioned directly below the ring forging, and can detect the height of the bottom edge of the ring forging. However, when this structure corrects eccentricity, if the limiting protrusion is pushed upwards by a spring beyond the positioning shaft, it cannot effectively position and abut the ring forging, affecting the overall working process.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned problems, this utility model discloses an eccentric correction device for ring forgings. The limiting structure of the limiting block allows the limiting block to remain within the positioning shaft, preventing slippage when the ring forgings come into contact.

[0006] The technical solution of this utility model is as follows: a ring forging eccentricity correction device, including a motor and a sleeve structure located on the base. The motor output shaft passes through the positioning shaft of the sleeve structure and is inserted into the inside of the ring forging. A limiting structure is provided on the limiting block of the positioning shaft groove. The limiting structure includes a limiting plate and a limiting spring located on the limiting block. The limiting structure is located in the limiting groove of the limiting block.

[0007] By adopting the above technical solution, when the ring forging passes the limiting block on the positioning shaft, the limiting block is pressed downward and pressed into the groove. When the ring forging has completely passed the limiting block, the limiting block is popped out of the groove by the large spring, and then the ring forging is stuck. The limiting structure on the groove and the limiting block can prevent the limiting block from being completely popped out by the large spring.

[0008] Preferably, the limiting groove is located on the lower side of the limiting block, the limiting groove has a square cross-section, and the bottom of the limiting groove is not higher than the upper surface of the positioning shaft.

[0009] By adopting the above technical solution, it is easy to install a limiting plate and a limiting spring in the limiting groove to prevent the limiting block from being ejected from the groove by the large spring.

[0010] Preferably, the limiting plate is located on the side wall of the positioning shaft groove, the limiting plate is parallel to the bottom of the groove, and the limiting plate extends into the interior of the limiting groove.

[0011] By adopting the above technical solution, when the limiting block is lifted upward by the large spring, the limiting plate can restrict the limiting block and prevent the bottom of the limiting block from exceeding the surface of the positioning shaft.

[0012] Preferably, the limiting block is in the shape of an inverted trapezoid, with the side of the trapezoid closest to the ring forging being the high side and the side on the outside being the low side, and the side of the limiting block located in the groove being the right-angled side.

[0013] By adopting the above technical solution, the high side can play a limiting and abutting role for the ring forging, and the inclined side between the high side and the low side can facilitate the sliding of the ring forging.

[0014] Preferably, the bottom of the limiting groove is connected to the limiting plate by a limiting spring. When the limiting spring is in the extreme compression state, the limiting block is located above the positioning shaft. When the limiting spring is in the extended state, the top of the limiting block is located inside the groove.

[0015] By adopting the above technical solution, the limiting spring can play a buffering role when the limiting plate presses and limits the limiting groove, preventing damage and wear between the two after multiple limiting operations, and improving the service life of the device.

[0016] Preferably, the bottom of the limiting block is connected to the bottom of the groove via a large spring, and the elastic force of the large spring is much greater than that of the limiting spring.

[0017] By adopting the above technical solution, the large spring can counteract the elastic force of the limiting spring and lift the limiting block, thus limiting the ring forging.

[0018] Preferably, at least two limiting blocks are symmetrically distributed circumferentially around the positioning shaft, and a limiting ring is provided at the end of the positioning shaft near the motor.

[0019] By adopting the above technical solution, the limiting ring and the limiting block can restrict the ring forging between the two, preventing the ring forging from shifting.

[0020] The advantages of this utility model are as follows: 1. This utility model sets a limiting groove in the limiting block, and sets a limiting spring and a limiting plate in the limiting groove. When the limiting block is lifted upward by the elastic force of the large spring, the limiting plate abuts against the limiting block through the limiting spring, preventing the limiting block from exceeding the upper surface of the positioning shaft and failing to abut against the ring forging.

[0021] 2. The limiting structure of the limiting block of this utility model can keep the limiting block inside the positioning shaft and prevent slippage when the ring forging comes into contact.

[0022] 3. This utility model provides a good foundation for improving the eccentricity correction efficiency of ring forgings, effectively improving the working efficiency of eccentricity correction. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1-4As shown, the ring forging eccentricity correction device includes a motor 2 and a sleeve structure located on the base 1. The base 1 is also equipped with an eccentricity detection structure, which is a conventional method in the field and will not be described in detail here. The output shaft of the motor 2 passes through the positioning shaft 3 of the sleeve structure and is inserted into the inside of the ring forging 10. The base 1 at the bottom of the ring forging 10 is also equipped with a lifting platform for supporting the ring forging 10. The limiting block 6 of the groove 4 of the positioning shaft 3 is equipped with a limiting structure. The limiting structure includes a limiting plate 9 and a limiting spring 8 located on the limiting block 6. The limiting structure is located in the limiting groove 7 of the limiting block. When the ring forging 11 is sleeved on the positioning shaft 3 and passes through the limiting block 6, the limiting block 6 is pressed downward, pressing the limiting block 6 into the groove 4. When the ring forging 11 has completely passed through the limiting block 6, the limiting block 6 is ejected from the groove 4 by the large spring 5, and then the ring forging 11 is stuck. The limiting structure on the groove 4 and the limiting block 6 can prevent the limiting block 6 from being completely ejected by the large spring 5.

[0030] The limiting groove 7 is located on the lower side of the limiting block 6. The limiting groove 7 has a square cross-section. The bottom of the limiting groove 7 is not higher than the upper surface of the positioning shaft 3. The limiting plate 9 and the limiting spring 8 are conveniently installed in the limiting groove 7 to prevent the limiting block 6 from being ejected from the groove 4 by the large spring 5.

[0031] The limiting plate 9 is located on the side wall of the groove 4 of the positioning shaft 3. The limiting plate 9 is parallel to the bottom of the groove 4 and extends into the interior of the limiting groove 7. When the limiting block 6 is lifted upward by the large spring 5, the limiting plate 9 can restrict the limiting block 6 and prevent the bottom of the limiting block 6 from exceeding the surface of the positioning shaft 3.

[0032] The limiting block 6 is in the shape of an inverted trapezoid. The side of the trapezoid closest to the ring forging 11 is the high side, and the side on the outside is the low side. The right-angled side of the limiting block 6 located in the groove 4 can limit and abut the ring forging. The inclined side between the high side and the low side can facilitate the sliding of the ring forging.

[0033] The bottom of the limiting groove 7 is connected to the limiting plate 9 via the limiting spring 8. When the limiting spring 8 is in the extreme compression state, the limiting block 6 is located above the positioning shaft 3. When the limiting spring 8 is in the extended state, the top of the limiting block 6 is located inside the groove 4. The limiting spring 8 can play a buffering role when the limiting plate 9 presses and limits the limiting groove 7, preventing damage and wear between the two after multiple limiting, and improving the service life of the device.

[0034] The bottom of the limiting block 6 is connected to the bottom of the groove 4 via the large spring 5. The elastic force of the large spring 5 is much greater than that of the limiting spring 8. The large spring 5 can counteract the elastic force of the limiting spring 8 and lift the limiting block 6, thus limiting the ring forging 11.

[0035] At least two limit blocks 6 are symmetrically distributed around the positioning shaft 3. A limit ring 10 is provided at the end of the positioning shaft 3 near the motor 2. The limit ring 10 and the limit blocks 6 can restrict the ring forging 11 between them to prevent the ring forging 11 from being displaced.

[0036] When the ring forging 11 is fitted onto the positioning shaft 3, as the ring forging 11 passes the limiting block 6, the limiting block 6 presses down on the large spring 5, and then the limiting block 6 retracts into the groove 4. When the ring forging 11 is located inside the limiting block 6, there is no pressing force on the upper part of the limiting block 6, and the limiting block 6 is popped out by the large spring 5. The limiting plate 9 plays a restrictive role on the limiting block 6, preventing the limiting block 6 from popping out of the groove completely.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
