Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically a clamping assembly for flange processing with a protective structure. Background Technology

[0002] Flange clamping assemblies are specialized tooling and fixture systems used to fix, position, and stabilize flange workpieces during machining processes (such as turning, milling, drilling, grinding, etc.). Their core function is to ensure that the flange does not shift or deform due to cutting forces, vibrations, or other factors during machining, thereby guaranteeing machining accuracy (such as dimensional tolerances, geometric tolerances, and surface roughness) and production safety.

[0003] In the prior art, the protective structure of some flange processing clamping assemblies is the soft gasket in the contact between the clamp and the flange. After long-term use, the soft gasket will gradually wear down, and it needs to be replaced. However, the soft gasket is directly glued and fixed to the clamp, which makes replacement troublesome, time-consuming and inefficient. Therefore, we propose a flange processing clamping assembly with a protective structure. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping assembly for flange processing with a protective structure, so as to solve the problem mentioned in the background art that the soft pad used as a protective structure will gradually wear down after long-term use, and the soft pad is directly glued and fixed to the clamp, making it troublesome to replace, taking longer to replace, and having low replacement efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping assembly for flange processing with a protective structure, comprising: a clamping seat, a sliding groove being provided at the top of the clamping seat, a double-headed electric push rod being installed at the bottom of the interior of the clamping seat, sliding strips being fixedly connected to both the front and rear ends of the double-headed electric push rod, and clamping blocks being fixedly connected to the top ends of both sliding strips. It also includes: a limiting rod fixedly connected inside the sliding groove; two sliding strips slidably connected inside to the outside of the limiting rod; two locking pins fixedly connected to the adjacent ends of the two clamping blocks; rubber pads provided at the adjacent ends of the two clamping blocks; two locking grooves opened at the distant ends of the two rubber pads; the locking pins and locking grooves are engaged; fixing holes are opened at the distant ends of the two rubber pads; an installation groove is opened inside the clamping block; a fixing post is fixedly connected inside the installation groove; a swing strip is rotatably connected to the outside of the fixing post; a driving groove is opened at the bottom end of the swing strip; a fixing strip is slidably connected inside the clamping block; the fixing strip engages with the fixing hole; a driving post is fixedly connected to the outside of the fixing strip; the outside of the driving post is slidably connected inside the driving groove; an elastic metal sheet is fixedly connected to the inner wall of the installation groove; the elastic metal sheet is used to push the fixing strip; and a pressing post is slidably connected inside the clamping block.

[0006] Among them, a limiting piece is fixedly connected to the outer side of the fixing strip, and the outer side of the limiting piece is in contact with the inner wall of the mounting groove.

[0007] The outer side of the swing bar is rotatably connected to the inside of the mounting groove, and one end of the pressing column is in contact with the outer side of the swing bar.

[0008] Each of the two clamping blocks has a limiting plate fixedly connected to one end of its closest point, with the top of the limiting plate in contact with the bottom of the rubber pad.

[0009] The lengths of the locking pins and the locking slots are the same, and the distance between the two locking pins on the clamping block is the same as the distance between the two locking slots on the rubber pad.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figures 1 to 7 This utility model provides a technical solution: a clamping assembly for flange processing with a protective structure, comprising: a clamping base 1, which serves as the mounting base for the entire clamping assembly, providing fixed support for components such as the sliding groove 2 and the double-headed electric push rod 3. Its rectangular block structure can be stably placed on the worktable of the processing equipment, ensuring the rigidity of the overall structure. The top of the clamping base 1 has a sliding groove 2, which provides a sliding track for the sliding strip 4. Through the fit design with the outer side of the sliding strip 4, the lateral displacement of the sliding strip 4 is limited, ensuring that the two clamping blocks 5 move closer or further away synchronously in the horizontal direction, avoiding misalignment when clamping the flange. The bottom of the internal part of the 1 is equipped with a double-headed electric push rod 3. The double-headed electric push rod 3 serves as a clamping power source. By controlling the extension and retraction of the output shafts at the front and rear ends, it drives the two sliding bars 4 and the clamping block 5 to move synchronously, thereby realizing the automatic clamping and release of the flange workpiece. The front and rear ends of the double-headed electric push rod 3 are fixedly connected to the sliding bars 4. The sliding bars 4 connect the double-headed electric push rod 3 and the clamping block 5, transmitting the power of the electric push rod to the clamping block 5. At the same time, by sliding on the sliding groove 2 and the limit rod 6, the linearity of the movement of the clamping block 5 is ensured. The top of the two sliding bars 4 are fixedly connected to the clamping block 5. The clamping block 5 is designed to install the rubber pad 8 and other structures. It also includes: a limiting rod 6 fixedly connected inside the sliding groove 2, the limiting rod 6 passing through the two sliding strips 4, further restricting the sliding direction of the sliding strips 4, preventing the sliding strips 4 from rotating around the vertical axis during movement, ensuring the perpendicularity and coaxiality of the clamping block 5 when clamping the flange, and reducing machining errors. The two sliding strips 4 are internally slidably connected to the outside of the limiting rod 6. Two locking posts 7 are fixedly connected to the near ends of the two clamping blocks 5. The locking posts 7 and the locking grooves 9 cooperate to form the initial positioning structure of the rubber pad 8 and the clamping block 5. Rubber pads 8 are provided at the near ends of the two clamping blocks 5, and two locking grooves 9 are provided at the far ends of the two rubber pads 8. The locking posts 7 and the locking grooves 9 are snapped together. Fixing holes 10 are provided at the far ends of the two rubber pads 8. An installation groove 11 is provided inside the clamping block 5. The existence of the installation groove 11 is to facilitate the installation of other structures. A fixing post 12 is fixedly connected inside the installation groove 11. The design of the fixing post 12 is to facilitate the fixing of the swing strip 13. The design of the swing strip 13 is... To cooperate with the drive groove 14 and thus drive the fixed bar 15, a swing bar 13 is rotatably connected to the outside of the fixed post 12. The bottom end of the swing bar 13 is provided with a drive groove 14. The drive groove 14 is designed to facilitate the sliding of the drive post 16. The fixed bar 15 is slidably connected inside the clamping block 5. The fixed bar 15 is engaged with the fixed hole 10. The drive post 16 is fixedly connected to the outside of the fixed bar 15. The drive post 16 is designed to drive the fixed bar 15 under the drive of the swing bar 13 and the drive groove 14. The outside of the drive post 16 is slidably connected inside the drive groove 14. An elastic metal sheet 17 is fixedly connected to the inner wall of the mounting groove 11. The elastic metal sheet 17 is designed to push the fixed bar 15 so that the fixed bar 15 is firmly engaged with the fixed hole 10. The elastic metal sheet 17 is used to push the fixed bar 15. A pressing post 19 is slidably connected inside the clamping block 5. The pressing post 19 is designed to press down on the swing bar 13, thereby driving the other side of the swing bar 13 to move.

[0017] A limiting piece 18 is fixedly connected to the outer side of the fixing strip 15. The limiting piece 18 is designed to limit the fixing strip 15. The outer side of the limiting piece 18 is in contact with the inner wall of the mounting groove 11.

[0018] The outer side of the swing bar 13 is rotatably connected to the inside of the mounting groove 11. One end of the pressing column 19 contacts the outer side of the swing bar 13. The swing bar 13 will rotate under the pressing of the pressing column 19 and cooperate with the driving groove 14 to drive the driving column 16.

[0019] Limiting plates 20 are fixedly connected to the adjacent ends of the two clamping blocks 5. The top of the limiting plate 20 contacts the bottom of the rubber pad 8. The presence of the limiting plate 20 allows the fixing strip 15 to be aligned with the fixing hole 10.

[0020] The lengths of the locking pins 7 and the locking slots 9 are the same. The distance between the two locking pins 7 on the clamping block 5 is the same as the distance between the two locking slots 9 on the rubber pad 8. After the locking pins 7 and the locking slots 9 are engaged, the clamping block 5 and the rubber pad 8 will be initially connected together.

[0021] The outer sides of the two sliding bars 4 are slidably connected to the inside of the sliding groove 2. The outer sides of the sliding bars 4 are in contact with the inner wall of the sliding groove 2. The sliding bars 4 are designed to drive the clamping block 5.

[0022] When a flange processing clamping assembly with a protective structure is needed to process a flange, first place the flange between the two clamping blocks 5 on the clamping seat 1. Then, activate the double-headed electric push rod 3. The double-headed electric push rod 3 will drive the two sliding bars 4 and the two clamping blocks 5, allowing the two clamping blocks 5 to clamp the flange. When the rubber gasket 8 wears, press the pressing column 19 by hand. The pressing column 19 will push the top part of the swing bar 13, thereby driving the other end of the swing bar 13. The swing bar 13 will then move through the driving groove 14... The moving column 16 drives the fixing strip 15, causing it to leave the fixing hole 10. At this point, the worn rubber pad 8 on the clamping block 5 can be removed. Through the engagement of the locking column 7 and the locking groove 9, a new rubber pad 8 can be installed. Once the fixing strip 15 is at the same level as the fixing hole 10, the hand pressing the pressing column 19 is released. The elastic metal piece 17 will reset the fixing strip 15, and the fixing strip 15 will re-engage with the fixing hole 10, thus fixing the rubber pad 8.

[0023] By controlling the engagement and disengagement of the fixing strip 15 with the fixing hole 10, the worn rubber pad 8 on the clamping block 5 can be replaced quickly. The replacement process is simpler, the replacement time is shorter, and the replacement efficiency is improved.

[0024] Example 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the two rubber pads 8 are slidably connected with fixing bolts 21 inside. The far ends of the two fixing bolts 21 are threaded to the inside of the two clamping blocks 5. The fixing bolts 21 are designed to fix the rubber pads 8 to the clamping blocks 5.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
