Description

Technical Field

[0001] The utility model relates to the field of clamping tools, in particular to a clamping tool for processing a valve sealing cover with fixed clamping. Background Art

[0002] The valve sealing cover is an important part of the valve assembly. Its main function is to ensure that the valve can be effectively sealed in the closed state to prevent fluid medium leakage. The valve sealing cover usually fits tightly with the sealing surface of the valve to achieve a good sealing effect. When processing the valve sealing cover, a clamping tool is usually required to clamp it. In the existing clamping tool, during the clamping process, the sealing valve cover can usually only be clamped oppositely by the clamping blocks. However, since the clamping blocks cannot adapt to fit the edge of the valve clamping cover, when the valve clamping blocks are being processed, they are prone to shift or deform, thus affecting the processing accuracy and safety of the sealing valve cover. Therefore, we propose a clamping tool for processing a valve sealing cover with fixed clamping to facilitate solving the problems mentioned above. Summary of the Utility Model

[0003] In order to overcome the problem that in the existing clamping tool, during the clamping process, the sealing valve cover can usually only be clamped oppositely by the clamping blocks. However, since the clamping blocks cannot adapt to fit the edge of the valve clamping cover, when the valve clamping blocks are being processed, they are prone to shift or deform, thus affecting the processing accuracy and safety of the sealing valve cover.

[0004] The technical solution of the utility model is as follows: A clamping tool for processing a valve sealing cover with fixed clamping includes a workbench, a conveying component and a clamping component; the workbench includes a table body and a fixing frame. There are two groups of fixing frames, and the two groups of fixing frames are symmetrically arranged at intervals along the upper end of the table body. A conveying groove is opened between the two groups of fixing frames. A conveying component for conveying and processing the valve sealing cover is arranged inside the conveying groove. A fixture receiving groove is opened at the upper end of the fixing frame, and a clamping component for clamping the valve sealing cover for processing is arranged inside the fixture receiving groove.

[0005] Preferably, through the combination of the conveying groove and multiple groups of through holes, the staff can install the conveying component in the conveying groove through the multiple groups of through holes, so that the valve sealing cover can be conveyed in the conveying groove through the conveying component. Through the combination of multiple groups of shock-absorbing bases, when the valve sealing cover is being clamped and processed, the multiple groups of shock-absorbing bases can reduce the vibration caused by the processing of the valve sealing cover. Through the combination of the first-level arc-shaped clamp and the second-level arc-shaped clamp, when it is necessary to clamp valve sealing covers of different sizes, the second-level arc-shaped clamp can rotate along the clamping shaft through the movable holes in the clamp sleeve, thereby shrinking the clamping space between the first-level arc-shaped clamp and the second-level arc-shaped clamp, so that the first-level arc-shaped clamp and the second-level arc-shaped clamp can adjust the clamping space to fit the valve sealing cover for clamping.

[0006] Preferably, a through hole is provided at the rear end of the clamping groove. Multiple groups of clamping grooves are provided, and the multiple groups of clamping grooves are linearly arranged along the upper end of the fixing frame. A rotating hole is provided on the side wall of the conveying groove. Multiple groups of rotating holes are provided, and the multiple groups of rotating holes are linearly arranged along the side wall of the conveying groove. By combining the conveying groove with the multiple groups of rotating holes, the staff can install the conveying component in the conveying groove through the multiple groups of rotating holes, so that the valve sealing cover can be conveyed in the conveying groove through the conveying component.

[0007] Preferably, a driving chamber is provided on one side of the conveying groove. The driving chamber is located inside the fixing frame. A shock-absorbing base is provided at the lower end of the table body. Multiple groups of shock-absorbing bases are provided, and the multiple groups of shock-absorbing bases are linearly arranged along the lower end of the table body. By combining the multiple groups of shock-absorbing bases, when the valve sealing cover is clamped and processed, the multiple groups of shock-absorbing bases can reduce the vibration caused by the processing of the valve sealing cover.

[0008] Preferably, the clamping component includes a hydraulic cylinder, a first-stage arc-shaped clamp and a second-stage arc-shaped clamp. The first-stage arc-shaped clamp is located inside the clamping groove. An activity groove is provided at the center of one end of the first-stage arc-shaped clamp. A clamping shaft is provided inside the activity groove. A clamping sleeve is provided at one end of the second-stage arc-shaped clamp close to the first-stage arc-shaped clamp. An activity hole is provided inside the clamping sleeve. The clamping sleeve is sleeved on the outer end of the clamping shaft through the activity hole. The second-stage arc-shaped clamp rotates and clamps along the clamping shaft through the clamping sleeve. By combining the first-stage arc-shaped clamp and the second-stage arc-shaped clamp, when it is necessary to clamp valve sealing covers of different sizes, the second-stage arc-shaped clamp can rotate along the clamping shaft through the activity hole inside the clamping sleeve, so as to contract the clamping space between the first-stage arc-shaped clamp and the second-stage arc-shaped clamp, so that the first-stage arc-shaped clamp and the second-stage arc-shaped clamp can adjust the clamping space to fit the valve sealing cover for clamping.

[0009] Preferably, a buffer protection pad is attached to the inner walls of the first-stage arc-shaped clamp and the second-stage arc-shaped clamp. A connecting block is provided at the rear side of one end of the first-stage arc-shaped clamp. The hydraulic cylinder is located on the side of the fixing block away from the conveying groove. A hydraulic push rod is provided at the rear end of the connecting block. The other end of the hydraulic push rod passes through the through hole and is connected to the hydraulic cylinder. By combining the hydraulic cylinder and the hydraulic push rod, when it is necessary to clamp the valve sealing cover, the multiple groups of clamping components on both sides of the conveying groove drive the hydraulic push rod through the hydraulic cylinder to push the first-stage arc-shaped clamp and the second-stage arc-shaped clamp to clamp the valve sealing cover oppositely.

[0010] Preferably, the conveying component includes a driving module, a rotating shaft and a transmission shaft. Multiple groups of transmission shafts are provided. The two ends of the multiple groups of transmission shafts respectively extend into the multiple groups of rotating holes on both sides of the conveying groove. The outer end of the transmission shaft is sleeved with a rotating shaft. The outer ends of the multiple groups of rotating shafts are sleeved with a conveyor belt. By combining the rotating shaft and the conveyor belt, when the valve sealing cover needs to be processed, the multiple groups of rotating shafts drive the conveyor belt to rotate, so that multiple valve sealing covers can be evenly conveyed into the conveying groove through the conveyor belt for clamping and processing.

[0011] Preferably, the driving module is located inside the driving chamber. One end of the transmission shaft passes through the rotating hole and extends into the driving chamber to be connected with the driving module. The combination of the driving module and the transmission shaft enables the driving module to drive multiple groups of transmission shafts to drive the rotating shaft to drive the conveyor belt to run inside the conveyor belt. At the same time, multiple groups of transmission shafts inside the conveyor belt can make the conveyor belt run more smoothly, avoiding the valve sealing cover from shifting due to instability when being conveyed on the conveyor belt.

[0012] Advantages of the present utility model:

[0013] 1. The combination of the conveying groove and multiple groups of rotating holes enables the staff to install the conveying component in the conveying groove through multiple groups of rotating holes, so that the valve sealing cover can be conveyed in the conveying groove through the conveying component. The combination of multiple groups of shock-absorbing bases enables the multiple groups of shock-absorbing bases to reduce the vibration generated during the processing of the valve sealing cover when the valve sealing cover is clamped and processed. The combination of the primary arc-shaped clamp and the secondary arc-shaped clamp enables the secondary arc-shaped clamp to rotate along the clamping shaft through the movable hole in the clamp sleeve when different-sized valve sealing covers need to be clamped, thereby shrinking the clamping space between the primary arc-shaped clamp and the secondary arc-shaped clamp, so that the primary arc-shaped clamp and the secondary arc-shaped clamp can adjust the clamping space to fit the valve sealing cover for clamping.

[0014] 2. The combination of the hydraulic cylinder and the hydraulic push rod enables the multiple groups of clamping components on both sides of the conveying groove to drive the hydraulic push rod to push the primary arc-shaped clamp and the secondary arc-shaped clamp to clamp the valve sealing cover oppositely when the valve sealing cover needs to be clamped. The combination of the rotating shaft and the conveyor belt enables the conveyor belt to rotate through multiple groups of rotating shafts when the valve sealing cover needs to be processed, so that multiple valve sealing covers can be evenly conveyed into the conveying groove through the conveyor belt to be clamped and processed. The combination of the driving module and the transmission shaft enables the driving module to drive multiple groups of transmission shafts to drive the rotating shaft to drive the conveyor belt to run inside the conveyor belt. At the same time, multiple groups of transmission shafts inside the conveyor belt can make the conveyor belt run more smoothly, avoiding the valve sealing cover from shifting due to instability when being conveyed on the conveyor belt, solving the problem that in the existing clamping tooling, during the clamping process, the sealing valve cover can usually only be clamped oppositely by the clamping blocks. However, since the clamping blocks cannot adapt to fit the edge of the valve clamping cover, the valve clamping blocks are prone to shift or deform during processing, thus affecting the processing accuracy and safety of the sealing valve cover.

[0024] Please refer toFigure 1-4 In this embodiment, the conveying assembly 3 includes a driving module 301 (the model of the driving module 301 is AQMD6030BLS-E3), a rotating shaft 303 and a transmission shaft 304. There are multiple groups of transmission shafts 304. The two ends of the multiple groups of transmission shafts 304 respectively extend into the multiple groups of rotating holes 106 on both sides of the conveying groove 104. The outer end of the transmission shaft 304 is sleeved with a rotating shaft 303, and the outer ends of the multiple groups of rotating shafts 303 are sleeved with a conveyor belt 302. By combining the rotating shaft 303 and the conveyor belt 302, when the valve sealing cover needs to be processed, the conveyor belt 302 is driven to rotate by the multiple groups of rotating shafts 303, so that multiple valve sealing covers can be evenly conveyed into the conveying groove 104 by the conveyor belt 302 for clamping and processing. The driving module 301 is located inside the driving chamber 107.

[0025] When working, the staff first place multiple valve clamping covers to be processed on the conveyor belt 302 in the conveying groove 104, and then the driving module 301 drives multiple groups of transmission shafts 304 to drive the rotating shaft 303 to drive the conveyor belt 302 to run inside the conveyor belt 302, so that the conveyor belt 302 conveys multiple valve clamping covers between the clamping assemblies 2 in multiple clamping grooves.

[0026] Then, the staff can rotate the secondary arc-shaped clamp 209 along the clamping shaft 207 through the moving hole in the clamping sleeve 208, thereby shrinking the clamping space between the primary arc-shaped clamp 205 and the secondary arc-shaped clamp 209, so that the primary arc-shaped clamp 205 and the secondary arc-shaped clamp 209 can adjust the clamping space to fit the valve sealing cover.

[0027] Finally, the staff uses the hydraulic cylinder 201 to drive the hydraulic push rod 202 to push the primary arc-shaped clamp 205 and the secondary arc-shaped clamp 209 to clamp the valve sealing cover oppositely, so that the valve sealing cover can be stably clamped during processing.

[0028] According to the above steps, the staff first convey multiple valve clamping covers to between the clamping assemblies 2 in multiple clamping grooves through the conveyor belt 302, then adjust the clamping space between the primary arc-shaped clamp 205 and the secondary arc-shaped clamp 209 to fit the valve sealing cover, and finally the staff uses the hydraulic cylinder 201 to drive the hydraulic push rod 202 to push the primary arc-shaped clamp 205 and the secondary arc-shaped clamp 209 to clamp the valve sealing cover oppositely.
