Description

Technical Field

[0001] The utility model relates to the technical field of pump cover processing, in particular to a pump cover processing device. Background Art

[0002] The pump cover refers to the part covering the top of the pump body. Its main function is to protect the components inside the pump body from contamination and external damage. It also acts as a seal to prevent fluid leakage. When producing the pump cover, processing equipment is required to process the inner hole of the pump cover into a shape that matches the pump body to ensure that the pump cover can be stably installed on the pump body.

[0003] In order to ensure good sealing, the pump cover in the prior art needs to maintain a high flatness on the side that cooperates with the pump body, and a plurality of through holes for exhaust and pressure relief need to be drilled on the peripheral side thereof, and the through holes are tapped and the peripheral side of the pump cover is correspondingly milled, so as to ensure that the size and shape accuracy of the peripheral side of the pump cover meet the corresponding design requirements, so as to achieve good sealing installation of the pump cover on the pump body. When processing the pump cover in the prior art, most of the peripheral sides of the pump cover are clamped first to complete the processing of the end face of the pump cover and the main channel hole. After the end face of the pump cover and the main channel hole are processed, the pump cover is pressed to complete the processing of the peripheral side of the pump cover. The pump cover produced under this processing method often cannot ensure a high flatness of the end face because its end face is pressed by the pressing workpiece, thereby resulting in a poor fit between the pump cover and the pump body, affecting the sealing of the pump cover and the pump body after installation;

[0004] If the end face of the pump cover is pressed first, and the peripheral side of the pump cover is processed, and after the peripheral side of the pump cover is processed, the peripheral side of the pump cover is clamped, and the end face and the main channel hole in the middle of the pump cover are processed, the peripheral side of the pump cover will be deformed under the clamping of the clamping workpiece, resulting in low dimensional accuracy of the peripheral side of the pump cover after processing, and a gap between the peripheral side of the pump cover and the pump body after installation, thereby affecting the sealing of the pump cover and the stability during operation after the pump cover is connected to the pump body, and the practical performance of the device is poor.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Example

[0034] Reference Figure 1-11The fixing plate 5 of described outer cover 1 is fixed on the fixing plate 5 of described outer cover 1, and the fixing plate 5 of described outer cover 1 is fixed on the fixing plate 5 of described outer cover 1.

[0035] It should be noted that in the present invention, the top of the limit plate 5 has an inverted angle. Through this design, it is convenient for the staff to place the pump cover 2 between the two limit plates 5 for limiting, thereby avoiding unnecessary jamming of the pump cover 2 during the installation process and improving the actual use effect of the device.

[0036] Reference Figure 2-7The clamping assembly includes a plurality of adjusting screws 7 rotatably arranged on the U-shaped mounting plate 3. The adjusting screw 7 is threadedly connected with a clamping plate 8 for clamping the pump cover 2 on both sides. The U-shaped mounting plate 3 is symmetrically provided with a slide rail 9. The clamping plate 8 is slidably mounted on the slide rail 9. The clamping plate 8 is provided with a square through groove 10 for facilitating the passage of the drilling device and the tapping device. The side of the clamping plate 8 that clamps the pump cover 2 is provided with an anti-slip rubber pad 11. One end of the adjusting screw 7 is fixedly connected to a bevel gear 12. The bevel gear 12 is meshed with a bevel gear 2 13. The U-shaped mounting plate The plate 3 is provided with a mounting hole 14 for facilitating the installation of bevel gear 12 and bevel gear 2 13. A rotating shaft 15 is fixedly provided in the middle of bevel gear 2 13. One end of the rotating shaft 15 is rotatably connected to the inner wall of the mounting hole 14. The other end of the rotating shaft 15 passes through the U-shaped mounting plate 3 and is connected to a synchronous pulley 16. The outer sleeve of the synchronous pulley 16 is provided with a synchronous belt 17 for transmission. The top of one of the rotating shafts 15 is fixedly connected to a driving motor 18. An L-shaped screwdriver is fixed on the U-shaped mounting plate 3 to facilitate the installation of the driving motor 18. The output end of the drive motor 18 passes through the L-shaped mounting plate 19 and is fixedly connected to the rotating shaft 15. Specifically, through the design of the clamping assembly, the lateral sides of the pump cover 2 are conveniently fixed so that the staff can process the end face of the pump cover 2 and the main through hole in the middle, effectively ensuring the stability of the pump cover 2 during the processing. By adjusting the design of the screw 7, the slide rail 9, the bevel gear 12, the bevel gear 2 13, the rotating shaft 15, the synchronous pulley 16, the synchronous belt 17, the L-shaped mounting plate 19 and the drive motor 18, the pump cover 2 can be easily fixed to the horizontal sides of the pump cover 2. The assembly only needs to use a driving motor 18 to drive the two adjusting screws 7 to rotate, and the clamping plate 8 threadedly connected to the adjusting screw 7 can be relatively clamped and moved along the slide rail 9, thereby achieving fixed clamping of the pump cover 2 on the processing device body 1 while reducing production costs, effectively improving the practical performance of the device, and through the design of the anti-slip rubber pad 11, it can reduce the damage caused by the clamping plate 8 to both sides of the pump cover 2 while increasing the friction between the clamping plate 8 and the pump cover 2, further improving the practical performance of the device;

[0037] It should be noted that, in the present invention, the thread on the adjusting screw 7 is designed with two sections of forward and reverse threads with opposite rotation directions. Through this design, when the adjusting screw 7 rotates, the two clamping plates 8 threadedly connected thereto can move toward or away from each other, thereby clamping and loosening the pump cover 2, effectively ensuring the normal operation of the clamping assembly; on the other hand, the drilling device, tapping device proposed in this embodiment and the milling device proposed in the background technology are all arranged on both sides and above the processing device body 1 using existing technology, and are not drawn in detail in the figure.

[0038] Reference Figure 6 and Figure 8-11The clamping assembly includes a receiving frame 20 fixedly set on the square frame 4, and a plurality of strip-shaped receiving rods 21 are evenly distributed on the receiving frame 20. The internal sliding cards of the plurality of strip-shaped receiving rods 21 are provided with L-shaped limit strips 22, and the interior of the strip-shaped receiving rods 21 is provided with a convex point 23 for limiting the position of the L-shaped limit strips 22. A connecting disc 24 is fixedly provided on the opposite side of the plurality of L-shaped limit strips 22, and a threaded sleeve 25 is fixedly connected to the middle of the connecting disc 24. The internal thread of the threaded sleeve 25 is connected to a threaded column 26, and the threaded column 26 is slidably set on the receiving frame 20. The top of the threaded column 26 is fixedly connected to a blocking disc 27 for blocking metal debris. The outside of the threaded sleeve 25 is fixedly provided with a plurality of The mounting strip 28 is rotatably connected to a plurality of connecting strips 29. The end of the connecting strip 29 away from the mounting strip 28 is rotatably connected to a clamping strip 30 for clamping the main channel hole opened on the pump cover 2. The top end of the clamping strip 30 is fixedly connected to a guide block 31. The blocking disk 27 is provided with a guide groove 32 matching the guide block 31. The clamping strip 30 is slidably clamped on the blocking disk 27 through the guide block 31. Specifically, through the design of the clamping assembly, the central main through hole opened on the pump cover 2 is clamped, thereby avoiding affecting the processing accuracy of the end face of the pump cover 2. The pump cover 2 is stably clamped in the processing device, so that the end face and the peripheral side of the pump cover 2 after processing can be maintained The higher the flatness, the better the practical performance of the device. The design of the receiving frame 20, the strip receiving rod 21, the L-shaped limit strip 22 and the connecting disc 24 limits the position of the threaded sleeve 25 so that it can only move with the overall movement of the threaded column 26 or move with the rotation of the threaded column 26, and cannot rotate with the threaded column 26, so that the threaded sleeve 25 can move upward under the rotation of the threaded column 26, and the connecting strip 29 connected to it is gradually horizontal, and the support strip 30 connected to its other end is opened so that the support strip 30 abuts against the inner wall of the main channel hole drilled on the pump cover 2. In this process, the design of the guide block 31 and the guide groove 32 is adopted. The position of the movement of the clamping strip 30 is restricted so that it can only move outward along the guide groove 32, thereby realizing the inner support clamping of the pump cover 2 by the clamping strip 30, effectively avoiding damage to the peripheral side and end surface of the pump cover 2, and improving the practical performance of the device. The design of the protrusion 23 and the blocking plate 27 limits the position of the L-shaped limit strip 22, so that when the clamping assembly falls due to its own gravity, it can abut against the bottom of the pump cover 2 under the engagement between the top end of the L-shaped limit strip 22 and the protrusion 23, thereby blocking the metal debris generated by drilling the pump cover 2, thereby preventing the metal debris from falling directly into the interior of the processing device body 1 and being difficult to clean, thereby improving the actual use effect of the device;

[0039] It should be noted that, in the present invention, the disc on the top of the blocking plate 27 that blocks the metal debris is made of a magnet and is fixedly screwed to the top of the blocking plate 27 by a threaded connection. Through this design, while achieving the absorption of metal debris by the blocking plate, the restrictiveness of the device during use is further reduced. When the size of the main channel hole to be drilled on the pump cover 2 increases, the staff can replace the disc to achieve the blocking of metal debris generated when drilling main channel holes of different sizes, thereby further improving the practicality of the device.

[0040] Reference Figure 8 and Figure 10-11 The screw column 26 is located at a section at the bottom of the receiving frame 20 and is fixedly connected to a column block 33. A slot 34 is opened inside the column block 33, and a column block 35 is fixed inside the slot 34. The top of the column block 35 has a rounded corner 36, and the bottom end of the column block 35 is fixedly connected to a second rotating shaft 37. The end of the second rotating shaft 37 away from the column block 35 passes through the U-shaped mounting plate 3 and is connected to a second driving motor 38. Specifically, through the design of the column block 33, the slot 34, the column block 35, the second rotating shaft 37 and the second driving motor 38, the second rotating shaft 37 can drive the threaded column 26 to rotate through the rotation of the second driving motor 38, thereby providing power for the clamping assembly and ensuring the normal operation of the device. The design of the rounded corner 36 improves the smoothness of the column block 35 when inserted into the column block 33, avoids unnecessary jamming, and improves the smoothness of the device.

[0041] Reference Figure 8 and Figure 11 The bottom of the square frame 4 is symmetrically provided with a receiving guide plate 39, and a receiving guide groove 40 is opened inside the receiving guide plate 39. The external rotation of the second rotating shaft 37 is connected with a strip-type card plate 41 that matches the receiving guide groove 40. Specifically, through the design of the receiving guide plate 39, the receiving guide groove 40 and the strip-type card plate 41, the top position of the second rotating shaft 37 is restricted to avoid unstable shaking of the second rotating shaft 37 during rotation due to the excessive length of the second rotating shaft 37, thereby further improving the stability of the operation of the device.

[0042] Reference Figure 3-6 The lifting assembly includes a plurality of adjusting screws 2 42 threadedly connected to both sides of the U-shaped mounting plate 3, and the two ends of the adjusting screws 2 42 are rotatably connected to the inner wall of the processing device body 1 respectively. The bottom end of the adjusting screw is fixedly connected to a synchronous pulley 2 43, and the outer sleeve of the synchronous pulley 2 43 is provided with a synchronous belt 2 44 for transmission. The top end of one of the adjusting screws 2 42 passes through the processing device body 1 and is connected to a driving motor 3 45. Specifically, through the design of the lifting assembly, while realizing the normal clamping of the central main through hole by the clamping assembly, it effectively avoids the blocking of the peripheral side of the pump cover 2 by the positioning clamping assembly, so that the corresponding drilling, tapping and milling processing can be performed on the peripheral side of the pump cover 2, effectively ensuring the normal operation of the device.

[0043] The use process of the pump cover 2 processing device provided by the utility model is as follows:

[0044] During the specific operation, the staff first places the pump cover 2 to be processed on the square frame 4 along the limit plate 5 to complete the positioning and clamping of the pump cover 2 on both sides in the longitudinal direction. Then the staff starts the drive motor 18, so that the drive motor 18 drives the rotating shaft 15 connected to its output end to rotate, and drives the other rotating shaft 15 to rotate through the cooperation of the synchronous pulley 16 and the synchronous belt 17. Then, the rotation of the rotating shaft 15 drives the bevel gear 2 13 fixed at its bottom end to rotate, so that the meshing bevel gear 12 on it The threaded rod 1 is driven to rotate, so that the clamping plate 8 threadedly connected to the threaded rod 1 moves relatively along the slide rail 9 to clamp the lateral sides of the pump cover 2 to complete the fixed clamping of the pump cover 2 on the processing device body 1. At this time, the driving motor 18 stops, and the blocking plate 27 on the clamping assembly is located at the bottom of the pump cover 2 and keeps a certain distance from the pump cover 2. Then the staff processes the end surface of the pump cover 2 and the pump body and the main channel hole. In this process, the blocking plate 27 collects a small amount of metal debris dropped by the drilling.

[0045] After the drilling process is completed, the staff starts the driving motor 18 to drive the splint 8 to move backward. In this process, the staff starts the driving motor 3 45 to drive the adjusting screw 2 42 connected to the output end of the driving motor 3 45 to rotate, and through the design of the synchronous pulley 2 43 and the synchronous belt 2 44, drives multiple adjusting screws 2 42 to rotate synchronously, and then drives the U-shaped mounting plate 3 threadedly connected to the adjusting screw 2 42 to move upward. In this process, the columnar block 35 fixed to the top of the rotating shaft 2 37 is gradually inserted into the columnar groove. The support and clamping components are moved upward along the receiving frame 20. During this process, the blocking disc 27 moves upward along the main channel hole and collects the metal debris remaining in the channel for a second time. After the blocking disc 27 moves to the top of the main channel hole, the driving motor 3 45 stops, and then the staff observes the metal debris adsorbed on the top of the blocking disc 27. If the adsorbed metal debris is large, the staff can wipe the metal debris off from the top of the blocking disc with a dry cloth. At this time, the clamping component is located at the top of the pump cover 2 and does not affect the subsequent drilling, tapping and milling processes.

[0046] Then the staff starts the driving motor 23 to drive the rotating shaft 237 to rotate, and drives the threaded column 26 to rotate through the column-shaped block 35 fixed at the top of the rotating shaft 237, so that the threaded sleeve 25 threadedly connected on the threaded column 26 gradually moves upward along the strip-shaped receiving rod 21. At this time, the connecting strip 29 rotatably connected to the outside of the threaded sleeve 23 gradually tends to be horizontal, and the clamping strip 30 rotatably connected to the other end of the connecting strip 23 gradually opens along the guide groove 32, so that the clamping strip 30 abuts against the inner wall of the main channel hole drilled on the pump cover 2, and then stops the driving motor 238, and performs corresponding processing on the peripheral side of the pump cover 2. After the processing of the pump cover 2 is completed, the driving motor 23 is started to stop the clamping assembly from clamping the pump cover 2, and then the driving motor 33 is started to reset the clamping assembly and the clamping assembly so that the clamping assembly is located at the bottom of the pump cover 2. After the clamping assembly is located on both sides of the pump cover 2, the pump cover 2 can be removed, and the processing of the pump cover 2 is completed.
