Description

Technical Field

[0001] This invention relates to the field of dimensional inspection technology, specifically to a device for verifying the dimensional forming of ring forgings. Background Technology

[0002] Ring dimensional verification is the process of measuring and evaluating the geometric dimensions, shape, and positional accuracy of ring forgings and machined parts. Using specialized measuring tools or laser-based testing equipment, basic dimensions such as inner and outer diameters, height, and wall thickness, as well as geometric tolerances such as roundness, cylindricity, end face flatness, end face perpendicularity, and coaxiality, are inspected to determine whether each indicator meets the requirements of drawings and standards. Its purpose is to control machining and heat treatment deformation, ensure the assembly accuracy, performance, and quality of the workpiece, and provide a basis for subsequent process acceptance and factory inspection. The invention disclosed in publication number CN118424076B is a dimensional verification device for ring forging. Through the structural design of the rotating cavity, positioning mechanism and functional mechanism, the functional mechanism can control two rotation states of the positioning mechanism, which are used for axial positioning and axial rotation for dimensional verification of the roundness of the ring forging, respectively. This prevents the dial indicator assembly from providing inaccurate data when detecting the roundness of the ring forging, and solves the technical problem of inaccurate verification data in dimensional verification devices for ring forging. However, this operating method has limited measurement capabilities when dealing with ring-shaped formed workpieces with post-processing characteristics. Although existing laser verification equipment can detect multiple items, it often requires an operator to assist in adjusting the workpiece's posture during the detection process, which is inconvenient.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see the appendix Figure 1-8 This application provides the following technical solutions.

[0019] A device for verifying the forming dimensions of ring-shaped forgings includes a verification table 1. A clamping and adjusting assembly is mounted on the verification table 1 via an adaptive moving component. The adaptive moving component includes two moving control boxes 2. The clamping and adjusting assembly includes a U-shaped synchronous frame 11 and two clamping positioning seats 5. A ring-shaped workpiece 30 is positioned between the two clamping positioning seats 5. Bearing connecting seats 4 are provided on both sides of the U-shaped synchronous frame 11. A rotating guide cylinder 7 is inserted into each of the two bearing connecting seats 4 via a through bearing. The two clamping positioning seats 5 are movably connected to the two rotating guide cylinders 7 respectively. The clamping and positioning seat 5 is guided and flipped. Two moving control boxes 2 are horizontally set on both sides of the upper end of the calibration table 1. The two bearing connecting seats 4 of the U-shaped synchronous frame 11 are located above the two moving control boxes 2. The lower end of each of the two bearing connecting seats 4 is provided with a lead screw slide 31. Each moving control box 2 is provided with a moving lead screw 33. The lead screw slide 31 is inserted into the moving control box 2 and sleeved with the moving lead screw 33. The U-shaped synchronous frame 11 is horizontally moved on the moving control box 2 through the lead screw slide 31 set on the bearing connecting seat 4.

[0020] Two clamping and positioning seats 5 are horizontally provided with prismatic connecting rods 8 at the center of their opposite sides. Prismatic guide grooves are opened through the center of the rotating guide cylinder 7. The prismatic connecting rods 8 are movably provided through the prismatic guide grooves of the rotating guide cylinder 7. U-shaped brackets 29 are provided on the side of the bearing connecting seat 4 away from the clamping and positioning seat 5. A clamping control cylinder 9 is horizontally provided on one side of the U-shaped bracket 29. A bearing connecting sleeve 10 is provided on the side of the prismatic connecting rod 8 that passes through the rotating guide cylinder 7. The bearing connecting sleeve 10 is connected to the telescopic rod of the clamping control cylinder 9 through the bearing sleeve. When the telescopic rod of the clamping control cylinder 9 extends, it pushes the clamping and positioning seat 5 connected by the bearing connecting sleeve 10 and the prismatic connecting rod 8 to move towards the center of the inspection table 1, thereby realizing the fixed clamping of the annular workpiece 30. The clamping force is adjusted with the adjustment of the clamping control cylinder 9.

[0021] The two clamping and positioning seats 5 have a V-shaped structure on one side of their opposite sides. Two roller grooves are symmetrically opened on one side of the V-shaped structure of each clamping and positioning seat 5. Positioning roller shafts 28 are rotatably inserted into each of the two roller grooves. The annular workpiece 30 is located between the two clamping and positioning seats 5 and is in contact with the four positioning roller shafts 28. The positioning roller shafts 28 are located on both sides of the V-shaped structure. When the four positioning roller shafts 28 are in contact with the annular workpiece 30, the annular workpiece 30 is clamped and fixed at four points. Side constraint plates 6 are provided at the center of both sides of the clamping and positioning seats 5. One side of each of the two side constraint plates 6 is in contact with the two sides of the annular workpiece 30. When the annular workpiece 30 is centered and clamped by the four positioning roller shafts 28, the annular workpiece 30 is located between the two side constraint plates 6 of the clamping and positioning seat 5, preventing the annular workpiece 30 from detaching from the side of the clamping and positioning seat 5.

[0022] A rotation control assembly is provided for the rotation control of the annular workpiece 30. The rotation control assembly is located inside the calibration table 1 and includes a bottom movable seat 25 and two drive rollers 27 to rotate the annular workpiece 30. A receiving groove is opened on the side of the U-shaped synchronous frame 11 away from the clamping positioning seat 5.

A flip control cylinder 13 is horizontally installed in each cylinder groove. One side of each of the two flip control cylinders 13 is connected to one side of the synchronous pull plate 12. A rotating guide cylinder 7 is inserted into a U-shaped bracket 29 and fitted with a gear 15. The two ends of the synchronous pull plate 12 extend out of the U-shaped synchronous frame 11 and are horizontally equipped with a gear plate 14. The two gear plates 14 are horizontally... A U-shaped bracket 29 is horizontally movable. The upper end of the U-shaped bracket 29 is provided with several actuating teeth, which mesh with the lower end of the actuating gear 15. When the flipping control cylinder 13 pulls or pushes the synchronous traction plate 12, it can control the actuating tooth plate 14 to rotate the actuating gear 15. At this time, the actuating gear 15 is fixedly connected to the rotating guide cylinder 7. The clamping positioning seat 5 is connected to the rotating guide cylinder 7 through the prismatic connecting rod 8 in a prismatic structure. When the rotating guide cylinder 7 rotates, it will drive the clamping positioning seat 5 and the prismatic connecting rod 8 to rotate together. The clamping control cylinder 9 and the prismatic connecting rod 8 are connected by the bearing connecting sleeve 10 and the bearing. The rotation of the prismatic connecting rod 8 and the clamping positioning seat 5 does not affect the stable clamping support of the clamping control cylinder 9.

[0023] The lower end of the inspection table 1 is provided with a base mounting base 24, and the upper end of the base mounting base 24 is provided with a telescopic groove. The lower end of the bottom support movable base 25 is provided with a plug-in seat, and the plug-in seat of the bottom support movable base 25 is movably plugged into the telescopic groove of the base mounting base 24. A bottom support telescopic cylinder 26 is vertically provided in the center of the telescopic groove, and the upper end of the bottom support telescopic cylinder 26 is plugged into the plug-in seat of the bottom support movable base 25. Both sides of the upper end of the bottom support movable base 25 are rotatably provided with drive rollers 27. When the annular workpiece 30 is vertically set, one side of the two drive rollers 27 contacts the annular workpiece 30. Before the rotating roller 27 contacts the annular workpiece 30, the annular workpiece 30 is moved to the top of the bottom support movable seat 25 by the movement control box 2 controlling the movement of the bearing connecting seat 4. The bottom support telescopic cylinder 26 pushes the bottom support movable seat 25 to lift, so that the driving roller 27 contacts the positioning roller shaft 28. At this time, a servo motor is connected to the driving roller 27 on one side. The servo motor can drive the driving roller 27 on one side to rotate. Then, the annular workpiece 30 rotates under the assistance of the driving roller 27 and the positioning roller shaft 28.

[0024] A detection component is set up to install and adjust the laser detection device. The detection component is located on one side of the calibration table 1. The detection component includes a U-shaped support frame 16 and a laser detection module 18. The U-shaped support frame 16 is vertically set on the upper side of one side of the calibration table 1. A height adjustment control cylinder 17 is vertically set at the center of the U-shaped support frame 16. A lifting plate 32 is horizontally set at the lower end of the height adjustment control cylinder 17. The two uprights of the U-shaped support frame 16 are slidably sleeved on both sides of the lifting plate 32. The laser detection module 18 is horizontally set on one side of the lifting plate 32 through a cantilever mounting plate. The height adjustment control cylinder 17 is bolted to the lifting plate 32, and the laser detection module 18 is bolted to the lifting plate 32. The height adjustment control cylinder 17 can control the lifting plate 32 and the laser detection module 18 to push up and down, so as to realize laser size detection at different heights.

[0025] The calibration table 1 has a groove on one side of the U-shaped support frame 16. A movable support plate 19 is horizontally inserted into the groove. T-shaped anti-detachment guide rods 20 are horizontally connected to both sides of the movable support plate 19 via guide rod connecting plates. The two T-shaped anti-detachment guide rods 20 are horizontally movably inserted through the calibration table 1. A spring pressure plate 21 is vertically installed at the center of the lower end of the movable support plate 19. A spring guide rod 22 is horizontally installed on one side of the spring pressure plate 21. The spring guide rod 22 movably inserts through the calibration table 1, and a telescopic spring 23 is sleeved on the side of the spring guide rod 22 near the spring pressure plate 21. When the annular workpiece 30 is vertically set, one side of the movable support plate 19 abuts against the sides of the two clamping positioning seats 5. When performing multi-dimensional functional testing, the annular workpiece 30 is first placed horizontally on the calibration table 1 and the movable support plate 19. Before the annular workpiece 30 is placed, the movable support plate 19, under the elastic support of the telescopic spring 23, has one end covering the upper part of the bottom movable seat 25. At this time, the annular workpiece 30 is below the laser detection module 18. The toothed plate 14 is moved to a horizontal position, and the lowermost side constraint plate 6 is flush with the movable support plate 19. The clamping control cylinder 9 pushes the clamping positioning seat 5 to move towards the position of the annular workpiece 30. The four positioning rollers 28 center and push the annular workpiece 30 for positioning. After positioning, the clamping control cylinder 9 pulls... The clamping and positioning seat 5 is moved away from the annular workpiece 30 to prevent the side constraint plate 6 from obscuring the dimensions of the annular workpiece 30. After the horizontal placement and inspection of the annular workpiece 30 are completed, the clamping and positioning seat 5 uses the clamping control cylinder 9 to horizontally clamp the annular workpiece 30. Then, the bearing connecting seat 4 is moved away from the positioning roller shaft 28 and the movable support plate 19 by the moving screw 33 of the moving control box 2. After the annular workpiece 30 is disengaged from the movable support plate 19, the toothed plate 14 is pushed by the flipping control cylinder 13 to control the rotation of the clamping and positioning seat 5, realizing the vertical adjustment or flipping adjustment of the annular workpiece 30. When it is necessary to inspect the inner and outer circumferential surfaces of the annular workpiece 30, the annular workpiece 30 is flipped to a vertical position. The rear movement control box 2 controls the bearing connecting seat 4 and the clamping positioning seat 5 to move directly above the bottom support movable seat 25 via the moving lead screw 33. During this period, the movable pallet 19 is pushed away from directly below the positioning roller shaft 28 by the clamping positioning seat 5, so that the bottom support movable seat 25 is raised at this time. The driving roller 27 contacts the lower end of the annular workpiece 30. At this time, the driving roller 27 rotates through the servo motor, which can realize the rotation of the annular workpiece 30 between the two clamping positioning seats 5. Before the annular workpiece 30 moves horizontally to the bottom support movable seat 25, the height of the positioning roller shaft 28 needs to be adjusted by the height adjustment control cylinder 17 according to the inner or outer ring of the annular workpiece 30 to adapt to the detection position.
