Description

Technical Field

[0001] The utility model relates to the technical field of forging production, and more specifically, to a measuring mechanism for forging diameter. Background Art

[0002] A large amount of steel is forged into forgings of specific shapes for use in production and manufacturing activities. When producing forgings, in order to ensure that the forgings meet the requirements, the data of the forgings need to be measured after forming. Compared with manual measurement with a ruler, specialized measuring mechanisms have higher accuracy and efficiency and are more commonly used.

[0003] In addition to the common measuring mechanism, the forgings are clamped by a fixed structure to ensure the stability of the forgings during measurement. However, the ordinary clamping mechanism can only clamp and fix, and does not have the positioning ability. When in use, the worker places the forgings on the measuring equipment and fixes them by the clamping mechanism. Whether the forgings are aligned depends on the worker's adjustment. The diameter of the forging has higher requirements for alignment accuracy than the length, width and other values. If the forgings are aligned with the measuring structure, the measured diameter will be smaller than the actual diameter. Moreover, the common measuring The fixing structure and measuring structure of the mechanism will be coordinated and coordinated. During measurement, only the outer end of the forging can be measured. Only when the forging itself is a circular ring and the overall diameter is measured can a good effect be achieved. Most forgings are not circular rings as a whole, but circular rings are set in the forgings, or the inner diameter of the circular ring structure needs to be measured. In this case, the common measuring mechanism will be inconvenient to use. In addition, when the forging is just formed, it has not been completely finalized. When the fixing mechanism contacts the forging, applies pressure to the forging, and pushes the forging, if the pressure is too large, it is easy to cause deformation of the forging, affecting the quality of the forging.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a forging diameter measuring mechanism, which has the following beneficial effects:

[0018] 1. The base supports the equipment, and the four sets of positioning plates around it cooperate for positioning and clamping. The matching cavity provides space, and the transmission gear and transmission rack cooperate. The positioning plate and the transmission rack are matched through the sliding block. Therefore, under the cooperation of multiple sets of transmission racks and the same transmission gear, multiple positioning plates move synchronously and move toward the center at the same time. Therefore, when the forging is clamped and fixed, the forging must be located in the center, ensuring that the forging is aligned with the measuring mechanism and the accuracy of the diameter measurement.

[0020] 3. The sliding groove is provided to provide moving space, and the forging is supported by the support table. The support table contacts the sliding groove through the rolling ball. Under the action of the rolling ball, the influence of friction is greatly reduced, so that the support table can move flexibly, which is convenient for the positioning plate to push the forging to move. Therefore, there is no need to provide excessive pressure, and the forging can be pushed to move for positioning and clamping, thereby reducing the pressure on the forging and ensuring the quality of the forging.

[0031] Support plates 8 are provided at both ends of the base 1, and a scale rod 9 is provided on the upper end of the support plate 8. A sliding measuring frame 10 is slidably connected at both ends of the scale rod 9, and an observation port 11 is opened on the sliding measuring frame 10, which cooperates with the scale rod 9.

[0032] In this embodiment, the equipment is supported by the base 1. When placing the forging, the forging is positioned and fixed by the cooperation of multiple positioning plates 2, and the movement of the positioning plates 2 is controlled. When a certain positioning plate 2 moves, it will drive the corresponding sliding block 5 to move. The sliding block 5 enters the matching cavity 3 through the sliding port 6, and drives the corresponding transmission rack 7 to move. The transmission rack 7 cooperates with the transmission gear 4 to rotate the transmission gear 4, thereby transmitting power to other transmission racks 7 through the transmission gear 4. Driven by the transmission rack 7 and the sliding block 5, the four groups of positioning plates 2 move synchronously and move toward the center of the base 1 at the same time, thereby contacting the forging and pushing the forging to move. Through the cooperation of the four groups of positioning plates 2, the forging is moved to the center of the base 1.

[0033] More specifically, after the positioning of the forging is completed, when measuring the diameter, the sliding measuring frame 10 is controlled to move, and under the support of the support plate 8, the two sets of sliding measuring frames 10 are moved on the scale rod 9 to align with the edge of the diameter to be measured below. The parameters on the surface of the scale rod 9 can be observed through the observation port 11, and the diameter of the forging can be read.

[0034] See also Figure 1 and Figure 3 As an implementation method for reducing pressure: a sliding groove 12 is opened on the base 1, a support platform 13 is arranged in the sliding groove 12, a rolling ball 14 is arranged at the lower end of the support platform 13, and the support platform 13 cooperates with the sliding groove 12 through the rolling ball 14.

[0035] Specifically, the forging is placed on the support table 13. When the positioning plate 2 pushes the forging to move, the support table 13 contacts the sliding groove 12 through the rolling ball 14. When moving, the rolling ball 14 rotates, which can greatly reduce the friction with the sliding groove 12. The sliding groove 12 also adopts a smoother surface, while the surface of the support table 13 is rougher, which makes the movement of the support table 13 more flexible, so that the positioning plate 2 can easily push the forging to move without requiring greater pressure.

[0036] Please refer to Figure 2 As a further implementation of the sliding block: the sliding block 5 includes a first sliding block 15 and a second sliding block 16 , the connection heights of the transmission racks 7 on the first sliding block 15 and the second sliding block 16 are different, and both are arranged on opposite positioning plates 2 .

[0037] Specifically, by dividing the sliding block 5 into two groups, the two groups of transmission racks 7 on the first sliding block 15 and the two groups of transmission racks 7 on the second sliding block 16 are arranged at different heights, thereby avoiding mutual interference between adjacent transmission racks 7 during movement.

[0038] Please refer to Figure 2 As a further implementation of the transmission rack: a first guide plate 17 and a second guide plate 18 are provided in the matching cavity 3, the first guide plate 17 is slidably matched with the transmission rack 7 on the first slider 15, and the second guide plate 18 is slidably matched with the transmission rack 7 on the second slider 16.

[0039] Specifically, when the transmission rack 7 cooperates with the transmission gear 4, the transmission rack 7 on the first slider 15 is supported and guided by the first guide plate 17, and the transmission rack 7 on the second slider 16 is supported and guided by the second guide plate 18, thereby ensuring stable cooperation between the transmission rack 7 and the transmission gear 4.

[0040] Please refer to Figure 1 and Figure 4As a further implementation of the sliding measuring frame: a positioning rod 19 is provided in the sliding connection of the sliding measuring frame 10, a sliding rod groove 20 is provided on the scale rod 9, and the positioning rod 19 cooperates with the sliding rod groove 20.

[0041] Specifically, when using the sliding measuring frame 10 to locate the edge of the diameter, the positioning rod 19 is moved along the sliding measuring frame 10, so that the positioning rod 19 is lowered and contacts with forgings of various heights. The sliding measuring frame 10 is driven to move by the positioning plate 2. After the positioning rod 19 contacts the edge of the forging diameter, the sliding measuring frame 10 will accurately reflect the value of the diameter.

[0042] Please refer to Figure 1 and Figure 4 As a further implementation of the positioning rod: a limiting head 21 is provided at the upper end of the positioning rod 19.

[0043] Specifically, the limiting head 21 contacts the upper end of the sliding measurement frame 10 to limit the movement of the positioning rod 19 and prevent the positioning rod 19 from sliding out of the sliding measurement frame 10 .

[0044] Please refer to Figure 1 and Figure 5 As a further implementation of the positioning plate: a telescopic sleeve 22 is provided on the support plate 8, and a pressure spring 23 is provided in the telescopic sleeve 22. One end of the pressure spring 23 is connected to the inner wall of the telescopic sleeve 22, and the other end is provided with a telescopic rod 24. The telescopic rod 24 is slidably matched with the telescopic sleeve 22, and the other end of the telescopic rod 24 is connected to the positioning plate 2.

[0045] Specifically, the telescopic sleeve 22 and the telescopic rod 24 cooperate to provide a protective support structure with variable length, and the pressure spring 23 provides thrust. Under the thrust provided by the pressure spring 23, the telescopic rod 24 slides along the telescopic sleeve 22, pushing the corresponding positioning plate 2 to move, thereby positioning the forging.

[0046] Please refer to Figure 1 As a further implementation of the positioning plate: a pulling rod 25 is slidably connected to the support plate 8, one end of the pulling rod 25 is connected to the positioning plate 2, and the other end is provided with a pulling handle 26.

[0047] Specifically, by controlling the pulling handle 26 and the transmission of the pulling rod 25, the movement of the positioning plate 2 is controlled, so that the positioning plate 2 moves toward the outer end of the base 1, the positioning and fixing of the forging is released, and the forging is conveniently taken out.

[0048] In summary, when the overall device is in use or running:

[0049] When using the equipment, by controlling the pulling handle 26, under the transmission of the pulling rod 25, the movement of the positioning plate 2 is controlled, so that the positioning plate 2 moves toward the outer end of the base 1 to provide space for the placement of the forging, and then the forging is placed on the support table 13. The support table 13 contacts the sliding groove 12 through the rolling ball 14 to support the forging, and then the pulling handle 26 is released. Under the thrust provided by the pressure spring 23, the telescopic rod 24 slides along the telescopic sleeve 22 to push the corresponding positioning plate 2 to move. When the corresponding positioning plate 2 moves, it will drive the corresponding sliding block 5 to move, and the corresponding sliding block 5 enters the matching cavity 3 through the sliding port 6, driving the corresponding transmission rack 7 to move. The transmission rack 7 cooperates with the transmission gear 4 to rotate the transmission gear 4, thereby transmitting power to other transmission racks 7 through the transmission gear 4, and the sliding block 5 is divided into two groups, the two groups of transmission racks 7 on the first slider 15 and the two groups of transmission racks on the second slider 16. 7 is arranged at different heights, so as to avoid the interference of adjacent transmission racks 7 when moving, and the transmission rack 7 on the first slider 15 is supported and guided by the first guide plate 17, and the transmission rack 7 on the second slider 16 is supported and guided by the second guide plate 18, so as to ensure the stable cooperation between the transmission rack 7 and the transmission gear 4, and the four groups of positioning plates 2 are synchronously moved toward the center of the base 1 by the driving of the transmission rack 7 and the sliding block 5, so as to contact with the forging and push the forging to move, and the forging is moved to the center of the base 1 by the cooperation of the four groups of positioning plates 2, and under the push of the positioning plate 2, when the support platform 13 moves with the forging, the rolling ball 14 rotates, which can greatly reduce the friction with the sliding groove 12, and the sliding groove 12 also adopts a smoother surface, while the surface of the support platform 13 is rougher, so that the movement of the support platform 13 is more flexible, so that the positioning plate 2 can easily push the forging to move without greater pressure.

[0050] After the forging is positioned, the diameter of the forging is measured. The sliding measuring frame 10 is controlled to move. Under the support of the support plate 8, the two sets of sliding measuring frames 10 are moved on the scale rod 9. The positioning rod 19 is controlled to move along the sliding measuring frame 10 so that the positioning rod 19 descends and contacts the forging below. The slidable positioning rod 19 can adapt to the measurement of forgings of various heights. The limiting head 21 contacts the upper end of the sliding measuring frame 10 to limit the movement of the positioning rod 19. There is no need to worry about the positioning rod 19 being moved during the sliding measurement. The measuring frame 10 slides out, and after the positioning rod 19 contacts the edge of the diameter of the forging, the sliding measuring frame 10 will be aligned with the edge of the diameter to be measured below. The parameters on the surface of the scale rod 9 can be observed through the observation port 11, which accurately reflects the value of the diameter and reads the diameter of the forging. After the measurement is completed, the positioning plate 2 is pulled by controlling the pulling handle 26. With the cooperation of the transmission gear 4 and the transmission rack 7, the four groups of positioning plates 2 are moved toward the outer end of the base 1, and the positioning and fixing of the forging are released, which is convenient for taking out the forging.
