Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically to a flange processing clamping and fastening assembly. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends, and also for connecting two pieces of equipment at their inlets and outlets. Flanges have multiple evenly distributed mounting holes; valve flanges require drilling during manufacturing. The existing technology has the following problems:

[0003] Chinese patent document CN221435741U discloses a clamping and fastening assembly for flange processing, including: a feeding mechanism including a support member and a pushing member located on the support member; a clamping mechanism including a clamping frame mounted on the support member and a driving member for driving the clamping frame member to work; the clamping frame member is slidably engaged on the upper side of the support member, and the driving member is mounted on the support member; the present invention places the flange to be processed on the pushing member, controls the pushing member to drive the flange to be processed to descend, and when the upper surface of the pushing member descends to the same level as the support member, controls the driving member to work, the driving member to drive the clamping frame member to slide on the support member, and when the clamping frame member slides, it pushes the flange to be processed against the support member, thereby positioning it and preventing the flange from moving during processing.

[0004] The aforementioned literature mainly utilizes a driving component to slide the clamping frame on the support platform, pushing the flange to be processed against the annular fixed frame for positioning. However, since the dimensions of the annular movable frame and the annular fixed frame included in the clamping frame are fixed and cannot be adjusted, it is impossible to clamp and fasten flanges of different diameters, resulting in poor applicability. In addition, the aforementioned literature only has the ability to clamp and fasten the side of the flange, but lacks the ability to clamp and fasten the top of the flange, resulting in poor clamping and fastening stability during flange processing. The flange may rotate and shift during drilling. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A flange processing clamping and fastening assembly includes an L-shaped base. A clamping platform plate is fixedly installed on the top of the vertical part of the L-shaped base.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a flange processing clamping and fastening assembly, including an L-shaped base 1. A clamping platform plate 2 is fixedly installed on the top of the vertical part of the L-shaped base 1. A clamping mechanism 3 is provided on the rear side of the top of the clamping platform plate 2. Adjustment mechanisms 4 are provided on the left and right sides of the front end of the clamping mechanism 3. A pressing mechanism 5 is provided between the opposite surfaces of the two adjustment mechanisms 4. The clamping mechanism 3 includes a clamping drive box 31, which is fixedly installed on the rear side of the top of the clamping platform plate 2. A clamping groove 32 is opened on the front side of the clamping drive box 31. A servo motor 33 is fixedly installed on the left side of the clamping drive box 31. The output shaft of the servo motor 33 passes through the inner cavity of the clamping groove 32 and is fixedly installed with a positive and negative threaded rod 34. The outer walls of the positive and negative threaded rod 34 are respectively provided with opposite threaded walls on the left and right sides. A clamping drive plate 35 is threadedly installed on the outer walls of the two threaded walls. The two adjustment mechanisms 4 are respectively located at the front end of the two clamping drive plates 35.

[0024] During clamping, the servo motor 33 is started by controlling the external wire, which drives the positive and negative threaded rod 34 in the clamping groove 32 of the clamping drive box 31 to rotate. The threaded walls with opposite threads on the left and right sides of the outer wall of the positive and negative threaded rod 34 are connected to the threads of the clamping drive plate 35, which drives the two clamping drive plates 35 to move the adjustment boxes 41 fixed at their respective front ends closer together. Thus, the two clamping cylinders 46 on the left and right sides are clamped and fastened to the left and right sides of the flange.

[0025] like Figure 3As shown, both adjustment mechanisms 4 include adjustment boxes 41. The two adjustment boxes 41 are fixedly connected to the front ends of the two clamping drive plates 35 respectively. Adjustment grooves 42 are opened on the opposite sides of the two adjustment boxes 41. The inner walls of the two adjustment grooves 42 are movably installed with positive and negative threaded rods 43. The front ends of the two positive and negative threaded rods 43 pass through the front of the two adjustment boxes 41 respectively and are fixedly installed with rotating handles 44. The outer walls of the two positive and negative threaded rods 43 are respectively opened with opposite threaded walls on the front and rear sides. The outer walls of the two threaded walls are threaded with moving plates 45. The end of the moving plate 45 away from the adjustment box 41 is fixedly installed with a clamping cylinder 46. The outer wall of the clamping cylinder 46 is wrapped with a rubber sleeve, which can improve stability when clamping the metal flange 13. The bottom of the clamping cylinder 46 is on the same horizontal line as the top of the clamping platform plate 2. The top front and rear sides of the two adjustment boxes 41 are fixedly coated with scale lines 47.

[0026] When machining assembly holes for flanges of different sizes, simply rotate the rotating handles 44 on the front of the two adjusting boxes 41 simultaneously to drive the positive and negative threaded rods 43 in the adjusting grooves 42 of the two adjusting boxes 41 to rotate. The threaded walls of the positive and negative threaded rods 43 with opposite threads on the front and rear sides of the outer wall are connected to the threads of the moving plates 45 to control the two moving plates 45 to move closer to each other, thereby driving the clamping cylinders 46 to move closer to each other, shortening the distance between the clamping cylinders 46. At the same time, according to the scale line 47 on the top of the adjusting box 41, the adjustment of the two clamping cylinders 46 on the left and right sides can be better controlled to be roughly consistent. Once the distance between the two clamping cylinders 46 on one side of the adjusting box 41 is shortened, when clamping the flange 13, it can fit and clamp a flange 13 with a smaller diameter. Conversely, rotating the handles 44 in reverse will reverse the positive and negative threaded rods 43, widening the distance between the two clamping cylinders 46, thereby clamping a flange 13 with a larger diameter.

[0027] like Figure 4 , Figure 5As shown, the clamping platform plate 2 has a telescopic hole 21 that runs vertically through it. An electric push rod 11 is fixedly installed at the top of the horizontal part of the L-shaped base 1. A cross-shaped placement plate 12 is fixedly installed at the output end of the electric push rod 11. The cross-shaped placement plate 12 is located in the inner cavity of the telescopic hole 21, and when the cross-shaped placement plate 12 is not raised, its top is on the same horizontal line as the top of the clamping platform plate 2. A flange 13 is provided on the top of the cross-shaped placement plate 12. The pressing mechanism 5 includes a lifting box 51, which is fixedly installed on the top of the L-shaped base 1. The lifting box 51 is located on the front side of the clamping drive box 31. The lifting box 51 has a lifting slide 52 on its front side. A servo motor 53 is fixedly installed on the top of the lifting box 51. The output shaft of the servo motor 53 passes through the inner cavity of the lifting slide 52 and is fixedly installed with a threaded rod 54. A flange pressing plate 55 is threaded on the outer wall of the threaded rod 54. The bottom front side of the flange pressing plate 55 is located above the flange 13. A rubber pad 56 is fixedly bonded to the bottom front side of the flange pressing plate 55. The bottom of the rubber pad 56 overlaps with the top of the flange 13.

[0028] When placing the flange 13, it can be placed on top of the cross-shaped placement plate 12 inside the expansion hole 21, with the assembly hole roughly offset from the cross-shaped placement plate 12 to avoid the cross-shaped placement plate 12 affecting the drill bit during drilling. Then, the clamping work can be carried out normally. After the flange 13 is clamped on both sides, the servo motor 53 powered by the external wire can be started to drive the threaded rod 54 in the lifting slide 52 to rotate. The flange pressing plate 55, which is threaded on the outer wall of the threaded rod 54, can drive the bottom front area of ​​the entire flange pressing plate 55 to move downward until the top of the flange 13 is supported by the rubber pad 56. The flange 13 is clamped more stably during the machining of the assembly holes. After machining, the output shaft of servo motor 2 53 is reversed, which drives the threaded rod 54 to reverse, causing the flange pressing plate 55 to rise to its highest position and move away from the flange 13. Then, the output shaft of servo motor 1 33 is reversed, which drives the forward and reverse threaded rod 1 34 to reverse, causing the two clamping cylinders 46 on one side of the two adjusting boxes 41 to move away from the flange 13. Then, the electric push rod 11 is directly activated, which can drive the cross-shaped placement plate 12 and the flange 13 on the top of the cross-shaped placement plate 12 to rise, making it easy to pick up.

[0029] The working principle of the flange machining clamping and fastening assembly will be explained in detail below.

[0030] like Figure 1-5As shown, when machining assembly holes for flanges of different sizes, simply rotate the rotating handles 44 on the front of the two adjusting boxes 41 simultaneously to drive the positive and negative threaded rods 43 in the adjusting grooves 42 of the two adjusting boxes 41 to rotate. The threaded walls of the positive and negative threaded rods 43, with opposite threads on their outer sides, are connected to the moving plates 45, controlling the two moving plates 45 to move closer together. This causes the clamping cylinders 46 to move closer together, shortening the distance between them. Simultaneously, the scale lines 47 on the top of the adjusting boxes 41 allow for better control of the approximate adjustment of the two clamping cylinders 46 on the left and right sides. Therefore, once the distance between the two clamping cylinders 46 on one side of the adjusting box 41 is shortened, when clamping the flange 13, it can fit snugly against a smaller diameter flange 13. During clamping, the servo motor 33 is started by controlling it with an external wire, which drives the positive and negative threaded rods 34 in the clamping groove 32 of the clamping drive box 31 to rotate. The threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rods 34 are connected to the threads of the clamping drive plate 35, which drives the two clamping drive plates 35 to move the adjusting boxes 41 fixed at their respective front ends closer together. Thus, the two clamping cylinders 46 on each side clamp the left and right sides of the flange. The flange 13 is clamped and secured. When placing the flange, it can be positioned on top of the cross-shaped placement plate 12 inside the expansion hole 21, with the assembly hole approximately offset from the cross-shaped placement plate 12 to prevent the cross-shaped placement plate 12 from affecting the drill bit during drilling. Then, normal clamping can proceed. After the flange 13 is clamped on both sides, the servo motor 53 powered by the external wire can be activated, causing the threaded rod 54 in the lifting slide 52 to rotate. This, combined with the flange pressing plate 55 threaded onto the outer wall of the threaded rod 54, drives the bottom front area of ​​the entire flange pressing plate 55 downwards until the rubber pad 56 presses against the flange. The top of the flange 13 is pressed and tightened, so that the flange 13 is clamped more stably when the assembly hole is processed. After the processing is completed, the output shaft of the servo motor 2 53 is reversed, which drives the threaded rod 54 to reverse, so that the flange pressing plate 55 rises to the highest point and moves away from the flange 13. Then, the output shaft of the servo motor 1 33 is reversed, which drives the positive and negative threaded rod 1 34 to reverse, so that the two clamping cylinders 46 on one side of the two adjusting boxes 41 move away from the flange 13. Then, the electric push rod 11 is directly started, which can drive the cross-shaped placement plate 12 and the flange 13 on the top of the cross-shaped placement plate 12 to rise, making it easy to pick up.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
