Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valve production equipment, in particular to a port grooving device for the production and processing of pressure reducing valves. Background Art

[0002] The grooving technology for pressure reducing valve ports is a key link in industrial manufacturing for the processing of pressure reducing valve ports. It mainly uses special devices to achieve efficient and accurate ring groove or incision processing. The horizontally moving grooving tool can move along the axis of the workpiece to achieve synchronous processing of the ring grooves at both ends of the pressure reducing valve.

[0003] For example, Chinese patent publication number CN222726088U discloses a port grooving device for pressure reducing valve production and processing, comprising a workbench, wherein a linear guide rail is fixedly connected to the bottom of the workbench, a sliding block is slidably connected to the top of the linear guide rail, a mounting plate is fixedly connected to the top of the sliding block, a driving assembly is fixedly connected to the top of the mounting plate, a mounting ring is fixedly connected to the outside of the mounting ring, a plurality of power plates are fixedly connected to the outside of the power plates, a connecting plate is rotatably connected to the outside of the connecting plate, and a rotating shaft is fixedly connected to the outside of the connecting plate.

[0004] The above cited document can quickly clamp and fix pressure reducing valves of different sizes, thereby reducing the working efficiency of the device and thus improving the working efficiency of the device, and can position pressure reducing valves of different sizes, thereby improving the flexibility of use of the device.

[0005] However, after the left and right ports of the pressure reducing valve are linearly grooved by two sets of longitudinal groove cutters, when the grooves of the upper and lower ports need to be adjusted, the pressure reducing valve needs to be manually released and the port positions need to be readjusted and fixed. This makes the groove opening steps of the pressure reducing valve ports cumbersome and inconvenient to operate. In addition, the groove debris attached to the ports after the pressure reducing valve is grooved needs to be transferred to the next process for further cleaning, which also increases the processing steps of the pressure reducing valve. Utility Model Content

[0006] The purpose of the utility model is to provide a port grooving device for the production and processing of pressure reducing valves, which can realize orderly switching and adjustment of the grooving of two groups of ports of the pressure reducing valve. The steps are closely connected, and there is no need to disassemble and assemble the fixture at the pressure reducing valve in the middle. The grooving is fast and convenient, and the grooved parts of the previous group can be cleaned synchronously, so that the subsequent processing steps of the pressure reducing valve are simplified.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0031] See also Figure 1-6 A port grooving device for producing and processing a pressure reducing valve includes a workbench 100, a backing plate 11, a grooving assembly 200, a clamping mechanism 400, and further includes:

[0032] The integrated pump 300 is fixedly mounted on the top of the inner wall of the workbench 100, and a flushing nozzle 31 is fixedly mounted on the output end of the integrated pump 300;

[0033] Support base 500, installed on both sides of the top of the pad 11;

[0034] The reduction motor 600 is fixedly mounted on one side of the workbench 100. A synchronous pulley 61 is mounted on one side of the workbench 100 close to the reduction motor 600 and is rotatably mounted on the shaft. A synchronous belt 62 is fixedly sleeved on the three sets of synchronous pulleys 61.

[0035] Among them, a through groove 111 is opened through the middle of the pad 11, and a clearance groove 112 is opened on both sides of the pad 11 near the fixed disk 700. The fixed disk 700 rotates in the corresponding clearance groove 112, so that the two sets of clamping mechanisms 400 can drive the clamped pressure reducing valve to flip, thereby adjusting the slot position of the pressure reducing valve port.

[0036] Among them, the clamping mechanism 400 also includes a first clamping jaw 40 and a second clamping jaw 41. The tail ends of the first clamping jaw 40 and the second clamping jaw 41 are movably penetrated by an insert plate 42. The first clamping jaw 40 and the second clamping jaw 41 are respectively fixedly installed on the insert plate 42 by adjusting bolts. The telescopic ends of the clamping cylinder 43 are respectively fixedly connected to the corresponding side surfaces of the insert plate 42. A pressure reducing valve is placed on the two groups of support seats 500. The first clamping jaw 40 and the second clamping jaw 41 are respectively used to clamp and fix the two sides of the pressure reducing valve. The first clamping jaw 40 and the second clamping jaw 41 can slide left and right on the corresponding insert plate 42 and are fixed by adjusting bolts. In this way, the two groups of clamping mechanisms 400 can be used to clamp and fix the end flanges of pressure reducing valves of different lengths.

[0037] Among them, linear slides 51 are fixedly installed on both sides of the top of the pad 11, and two groups of support seats 500 are fixedly installed on the corresponding matching sliders in the linear slide 51. The round neck at the end flange of the pressure reducing valve can be placed on the two groups of support seats 500. The height of the two groups of support seats 500 and the installation height of the clamping mechanism 400 are greater than the overall length of the pressure reducing valve to be slotted, so that when the pressure reducing valve is flipped, it can avoid interference with the pad 11.

[0038] Among them, a ring sleeve 71 is fixedly installed on the inner wall of the workbench 100 near the fixed plate 700. The ring sleeve 71 is used to shield and protect the external teeth of the worm gear 72. The fixed plate 700 is located inside the ring sleeve 71, so that the external teeth of the worm gear 72 can be wrapped and protected by the ring sleeve 71.

[0039] In this embodiment, the slotting assembly 200 drives the slotting knife driven by the cylinder jacking motor, so that the slotting knife can move the guide pressure reducing valve end to slot, and the first clamping jaw 40 and the second clamping jaw 41 in the clamping mechanism 400 can slide left and right on the corresponding inserting plate 42 and be fixed by adjusting bolts, and the two sets of clamping mechanisms 400 can be telescopically adjusted by the corresponding clamping cylinder 43, so that the two sets of clamping mechanisms 400 can be adapted to clamp and fix at the end flanges of pressure reducing valves of different lengths. The slotting assembly 200 and the clamping mechanism 400 in the pressure reducing valve port slotting device are adjusted to the existing technical solution and will not be described in detail here.

[0040] In this embodiment, the synchronous pulley 61 and the synchronous belt 62 are driven by the output end of the reduction motor 600, so that the ends of the two groups of worm gears 73 are synchronously driven by the corresponding synchronous pulleys 61, thereby making the two groups of worm gears 72 synchronously driven, so that the two groups of fixed plates 700 can drive the corresponding clamping cylinders 43 and the pressure reducing valves on the end clamping claws to flip, thereby realizing the adjustment of the slot positions of the upper and lower groups of ports and the left and right groups of ports of the pressure reducing valve. In this process, there is no need to disassemble the pressure reducing valve from the clamping mechanism 400 to adjust the position and then re-clamp and fix it, thereby realizing the orderly switching of the two groups of ports of the pressure reducing valve and adjusting the slots. The steps are closely connected, and there is no need to disassemble and assemble the clamp at the pressure reducing valve in the middle, and the slotting is fast and convenient.

[0041] The fixed plates 700 are rotatably mounted on the front and rear sides of the inner wall of the workbench 100 via a rotating shaft. A clamping cylinder 43 is fixedly mounted in the middle of the adjacent surfaces of the two sets of fixed plates 700. A worm gear 72 is integrally formed on the exterior of the fixed plates 700. Worm gears 73 are mounted on both sides of the bottom of the pad 11 near the edges of the fixed plates 700. A cam 74 is fixedly mounted coaxially with the fixed plates 700 on the front of the workbench 100. Example

[0042] Based on Example 1, this example introduces a port grooving device for pressure reducing valve production and processing, such as Figure 4 、 Figure 6 Shown, including:

[0043] The press switch 800 is installed on the side of the pad 11 close to the cam 74. Its model is self-resetting la3811bn. The press switch 800 can open the integrated pump 300 after being pressed by the cam 74. After the protruding part of the cam 74 moves away from the press switch 800, the press switch 800 can automatically bounce up through the internal elastic part, thereby preventing the integrated pump 300 from continuously opening the flushing nozzle 31 and avoiding unnecessary waste of cleaning fluid.

[0044] Among them, a bracket 81 is fixedly installed on the inner wall of the workbench 100 near the press switch 800, and the press switch 800 is fixedly installed on the bracket 81. The bracket 81 is used to electrically control the integrated pump 300. Bearing seats 731 are fixedly installed on the two side edges of the bottom of the pad 11. The worm 73 is rotatably installed between the two groups of bearing seats 731. The ends of the two groups of worms 73 are respectively fixedly connected to the rotating shafts of the corresponding synchronous pulleys 61 ends. The outer edges of the worm 73 are respectively engaged with the outer edges of the corresponding worm wheels 72 on the same side. When the fixed plate 700 on the front side of the workbench 100 is rotated and adjusted, the corresponding cam 74 protruding part can press the press switch 800 below, so that the integrated pump 300 on the top is turned on, and the cleaning liquid is sprayed on the slotted port of the pressure reducing valve below through the flushing nozzle 31, so that the metal debris can be simultaneously cleaned from the slotted port of the adjusted pressure reducing valve end.

[0045] In this embodiment, when the fixed plate 700 near the front side of the workbench 100 is rotated and adjusted, the cam 74 can rotate synchronously with the corresponding fixed plate 700, so that the protruding portion of the cam 74 can press the push switch 800 on the bracket 81, thereby turning on the integrated pump 300 on the top, and spraying the cleaning liquid through the flushing nozzle 31 onto the slotted port of the pressure reducing valve below. In this way, the slotted port at the end of the adjusted pressure reducing valve can be cleaned of metal debris simultaneously, and there is no need to further clean the pressure reducing valve later.

[0046] Working principle: When grooving the port of the pressure reducing valve, the flanged round necks on both sides of the pressure reducing valve end are placed on two sets of support seats 500. Then, the clamping cylinder 43 drives the two sets of adjusted clamping jaws to extend, so that the pressure reducing valve can be clamped in the center.

[0047] Then, groove the pressure reducing valve port by using the groove components 200 on both sides;

[0048] Finally, when adjusting the opening positions of the upper and lower ports of the pressure reducing valve, the two sets of linear slides 51 can drive the two sets of support seats 500 to slide toward the inner walls of the workbench 100, thereby preventing interference with the support seats 500 when the pressure reducing valve is axially flipped.

[0049] At this time, the output end of the reduction motor 600 drives the synchronous pulley 61 and the synchronous belt 62, so that the ends of the two sets of worm gears 73 are synchronously driven through the corresponding synchronous pulleys 61, thereby making the two sets of worm gears 72 synchronously driven, so that the two sets of fixed plates 700 can drive the corresponding clamping cylinders 43 and the pressure reducing valves on the end clamping jaws to flip, thereby adjusting the slot positions of the upper and lower ports and the left and right ports of the pressure reducing valve, and then the slotting assembly 200 can continue to slot the upper and lower ports of the pressure reducing valve;

[0050] In addition, when the fixed plate 700 near the front side of the workbench 100 is rotated and adjusted, the cam 74 can rotate synchronously with the corresponding fixed plate 700, so that the protruding part of the cam 74 can press the push switch 800 on the bracket 81, thereby turning on the integrated pump 300 on the top, and spraying the cleaning liquid through the flushing nozzle 31 onto the slotted port of the pressure reducing valve below. In this way, the metal debris can be cleaned synchronously from the slotted port at the end of the adjusted pressure reducing valve, and there is no need to further clean the pressure reducing valve afterwards.

[0051] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
