Description

Technical Field

[0001] This invention relates to the field of valve flange hole processing technology, specifically to a valve flange hole chamfering device that facilitates the removal of waste debris. Background Technology

[0002] In the valve manufacturing industry, flanges are key connecting components, and their quality directly affects the overall performance of the valve. Chamfering the flange bore is an indispensable processing step, aimed at removing burrs from the bore edges and optimizing connection strength and sealing performance.

[0003] However, existing chamfering equipment still has the following problems when chamfering flange holes:

[0004] 1. Because a large amount of waste chips generated during the chamfering process tend to accumulate in the processing area, it not only interferes with the normal operation of the cutting tool, causing problems such as tool wear and reduced processing accuracy, but also requires frequent machine shutdowns for cleaning. Furthermore, because the waste chips are scattered everywhere, cleaning is time-consuming and labor-intensive.

[0005] 2. Because the valve flange has multiple mounting holes, the fixtures and chamfer positions need to be adjusted frequently, which seriously reduces production efficiency. Summary of the Invention

[0019] Beneficial effects

[0020] Compared with the prior art, the present invention provides a valve flange hole chamfering device that facilitates the cleaning of waste debris, and has the following beneficial effects:

[0021] 1. This invention collects the waste generated during chamfering using an installation disc, thus facilitating subsequent cleaning.

[0022] 2. The present invention features a quick-release component. When cleaning is required, simply pull the mounting plate upwards. This releases the magnetic attraction between the magnetic block 2 and the mounting plate, as well as the engagement between the keyway and the key strip. Then, the waste in the mounting plate can be directly poured into the collection box, making it simple and convenient to use.

[0023] 3. The present invention can accurately position the valve flange using a positioning pin, and the height of the positioning pin is lower than the thickness of the valve flange, so the positioning pin does not affect the chamfering operation of the mounting holes of the valve flange.

[0024] 4. This invention uses a rotary drive assembly to make gear one drive the rotating shaft to rotate at a reduced speed until the next mounting hole of the valve flange corresponds to the chamfering drill bit, thereby achieving chamfering of multiple mounting holes of the valve flange and avoiding repeated disassembly and installation.

[0025] 5. By activating the electromagnetic lock, the latch of the electromagnetic lock extends and engages with the pin hole, thereby fixing the rotating shaft through the locking positioning plate, thus avoiding wobbling during chamfering and affecting the chamfering accuracy.

[0026] 6. This invention uses a lateral translation component to move the valve flange with one side chamfered out of the processing station. Then, the operator flips the valve flange and repositions it, thus avoiding the danger of flipping and picking up the valve flange directly at the processing station without stopping the machine.

[0043] Reference Figures 1-8A valve flange hole chamfering device for easy cleaning of waste includes a processing platform 2. A mounting bracket 3 and a side support 102 are bolted to the top of the processing platform 2. Two guide rods 4 are mounted inside the mounting bracket 3 via a horizontal fixed seat. A transverse moving plate 5 is slidably connected between the two guide rods 4 via a sliding table. A rotating shaft 606 is rotatably connected inside the transverse moving plate 5 via a bearing. A mounting plate 7 is connected to the top of the rotating shaft 606 via a quick-release assembly. A retaining cover 704 is welded to the outer circumference of the mounting plate 7. A positioning assembly for installing the valve flange is provided inside the mounting plate 7. The transverse moving plate 5... The bottom of the machining platform 2 is equipped with a rotary drive assembly 6 that drives the mounting plate 7 to rotate. The top of the machining platform 2 is equipped with a transverse translation assembly 8 that drives the transverse moving plate 5 to move laterally along the guide rod 4. One side of the side bracket 102 is equipped with a chamfering assembly 1 for chamfering the valve flange. The chamfering assembly 1 includes two vertical guide rails 104 that are bolted to one side of the side bracket 102. A vertical moving plate 103 is slidably connected between the two vertical guide rails 104 via a slide table. A chamfering motor 106 is bolted to one side of the vertical moving plate 103. One end of the output shaft of the chamfering motor 106 is mounted with a chamfering head via a drill chuck. The angle drill bit 107 has a vertical drive cylinder 101 at the top of the side support 102, which drives the vertical moving plate 103 to move vertically along the vertical guide rail 104. A pressure plate 105 is bolted to one side of the vertical moving plate 103. Two connecting rods 108 are inserted into the bottom of the pressure plate 105. A pressure strip 109 is bolted between the bottom ends of the two connecting rods 108. A tension spring 110 is fitted between the top ends of the two connecting rods 108 and the pressure plate 105. When chamfering, the chamfering motor 106 is started first. The rotation of the chamfering motor 106 drives the chamfering drill bit 107 to rotate through the drill chuck. Then, the vertical drive cylinder 101 is activated. The vertical drive cylinder 101 extends and drives the vertical moving plate 103 to move downward along the vertical guide rail 104 until the pressure strip 109 set on the pressure plate 105 contacts the valve flange. The vertical moving plate 103 continues to move downward. At this time, the clamping spring 110 is stretched and generates tension, thus pressing and fixing the valve flange. Then the vertical moving plate 103 continues to move downward until the rotating chamfering drill bit 107 contacts the mounting hole opened on the valve flange and performs chamfering operation on the mounting hole. At this time, the waste generated by chamfering is discharged on the mounting plate 7.

[0044] The quick-release assembly of this invention includes a rotating base 601 fixed to the top of a rotating shaft 606 by bolts. The top of the rotating base 601 has multiple equidistant connecting key strips 602. The bottom of the mounting plate 7 has a groove 604 that conforms to the shape of the rotating base 601. The groove 604 has multiple connecting keyways 605 that mate with the connecting key strips 602. The rotating base 601 has an adsorption component inside for adsorbing the mounting plate 7. The adsorption component is a second magnetic block 603 embedded inside the rotating base 601. The second magnetic block 603 can be used with the mounting plate 7. When the disk 7 contacts and magnetic attraction occurs, the disk 7 is pulled upwards directly when cleaning is required. This releases the magnetic attraction of the second magnetic block 603 to the disk 7 and the engagement of the keyway 605 and the key bar 602. Then, the waste in the disk 7 is poured into the collection box. A second cleaning can be performed by blowing air with a handheld air gun. After the waste is cleaned, the disk 7 is re-engaged on the rotating base 601 through the groove 604. At this time, the keyway 605 and the key bar 602 are re-engaged, and the second magnetic block 603 magnetically fixes the rotating base 601.

[0045] The positioning component of this invention includes multiple positioning pins 701 fixed inside the mounting plate 7 by bolts. Each positioning pin 701 corresponds to a mounting hole in the valve flange. The height of each positioning pin 701 is lower than the thickness of the valve flange. The mounting plate 7 has a clearance groove 702 inside to avoid the protruding part of the valve flange. Multiple magnetic blocks 703 are embedded in the clearance groove 702 to attract the valve flange. The positioning pins 701 can accurately position the valve flange. Since the height of the positioning pins 701 is lower than the thickness of the valve flange, the positioning pins 701 do not affect the chamfering operation of the mounting holes of the valve flange. The installed valve flange can be magnetically fixed by the magnetic blocks 703.

[0046] The rotary drive assembly 6 of this invention includes a second gear 610 bolted to the bottom of a rotating shaft 606. A base frame 607 is bolted to the bottom of the transverse moving plate 5. A rotary drive motor 608 is bolted inside the base frame 607. One end of the output shaft of the rotary drive motor 608 passes through the base frame 607 and is bolted to a first gear 609 that meshes with the second gear 610. A positioning disc 613 is bolted to the outer circumference of the rotating shaft 606. Multiple equally spaced pin holes 612 are provided on the outer circumference of the positioning disc 613. The transverse moving plate 5... The bottom of the movable plate 5 is fixed with an electromagnetic lock 611 that mates with the pin hole 612 by bolts. When adjusting the mounting hole position of the valve flange, the rotary drive motor 608 is started first. The rotary drive motor 608 rotates, causing gear 1 609 to drive the rotating shaft 606 to rotate at a reduced speed through gear 2 610 until the next mounting hole of the valve flange corresponds to the chamfering drill bit 107. At this time, the electromagnetic lock 611 is started again. The locking tongue of the electromagnetic lock 611 extends and engages in the pin hole 612, thereby fixing the rotating shaft 606 by the locking positioning plate 613.

[0047] The lateral translation component 8 of this invention includes a lateral support 804 bolted to the top of the processing platform 2. A threaded rod 802 is rotatably connected to the interior of the lateral support 804 via bearings. A threaded cylinder 803 is threaded to one side of the threaded rod 802. A connecting frame 801 is bolted to the top of the threaded cylinder 803 and is fixed to the lateral moving plate 5. A lateral translation drive motor 805 is provided at the end of the lateral support 804 to drive the threaded rod 802 to rotate around its axis. By activating the lateral translation drive motor 805, the lateral translation... The translation drive motor 805 rotates, driving the threaded rod 802 to rotate. The rotation of the threaded rod 802 causes the threaded cylinder 803 to move along the guide rod 4 via the connecting frame 801, thus moving the valve flange with one chamfered side out of the processing station. Then, the operator flips the valve flange and repositions it. At this time, the translation drive motor 805 is started, and the translation drive motor 805 rotates in the opposite direction, driving the translation plate 5 to move in the opposite direction and reset. This avoids flipping and picking up the valve flange directly at the processing station without stopping the machine, which is somewhat dangerous.

[0048] The present invention is used in the following steps:

[0049] S1: When chamfering, first place the valve flange in the mounting plate 7, and then the valve flange can be accurately positioned by the positioning pin 701. The height of the positioning pin 701 is lower than the thickness of the valve flange. Therefore, the positioning pin 701 does not affect the chamfering operation of the mounting hole of the valve flange, and the installed valve flange can be magnetically fixed by the magnetic block 703.

[0050] S2: Then start the chamfering motor 106. The chamfering motor 106 rotates and drives the chamfering drill bit 107 to rotate through the drill chuck. Then start the vertical drive cylinder 101. The vertical drive cylinder 101 extends and drives the vertical moving plate 103 to move downward along the vertical guide rail 104 until the pressure strip 109 set on the pressure plate 105 contacts the valve flange. The vertical moving plate 103 continues to move downward. At this time, the clamping spring 110 is stretched and generates tension, so the valve flange is clamped and fixed. Then the vertical moving plate 103 continues to move downward until the rotating chamfering drill bit 107 contacts the mounting hole opened on the valve flange and performs chamfering operation on the mounting hole. At this time, the waste generated by chamfering is discharged on the mounting plate 7.

[0051] S3: After the chamfering of one mounting hole of the valve flange is completed, when chamfering the next mounting hole of the valve flange, firstly, the vertical drive cylinder 101 shortens and drives the chamfering drill bit 107 to move upward and reset. Then, the rotary drive motor 608 is started. The rotary drive motor 608 rotates and causes gear 1 609 to drive the rotating shaft 606 to perform a decelerated rotational motion through gear 2 610 until the next mounting hole of the valve flange corresponds to the chamfering drill bit 107. At this time, the electromagnetic lock 611 is started. The locking tongue of the electromagnetic lock 611 extends and is locked into the pin hole 612, thereby fixing the rotating shaft 606 through the locking positioning plate 613.

[0052] S4: Then repeat the actions of S2 and S3 until one side of the valve flange is completely chamfered, and then immediately perform chamfering on the other side of the valve flange.

[0053] S5: At this time, the transverse translation drive motor 805 is started. The transverse translation drive motor 805 rotates and drives the threaded rod 802 to rotate. The rotation of the threaded rod 802 causes the threaded cylinder 803 to drive the transverse moving plate 5 to move along the guide rod 4 through the connecting frame 801. This causes the valve flange with one side chamfered to move out of the processing station. Then, the worker flips the valve flange and repositions it. At this time, the transverse translation drive motor 805 is started. The transverse translation drive motor 805 rotates in the opposite direction and drives the transverse moving plate 5 to move in the opposite direction and reset. Then the above chamfering operation is repeated until the mounting holes on both sides of the valve flange are chamfered.

[0054] S6: When cleaning is required, simply pull the mounting plate 7 upwards. This releases the magnetic attraction of the second magnetic block 603 to the mounting plate 7 and the engagement of the connecting keyway 605 and the connecting key strip 602. Then, directly pour the waste from the mounting plate 7 into the collection box. A second cleaning can then be performed using a handheld air gun. After the waste is cleaned, the mounting plate 7 is re-engaged onto the rotating base 601 via the slot 604. At this time, the connecting keyway 605 and the connecting key strip 602 are re-engaged, and the second magnetic block 603 magnetically fixes the rotating base 601, thus enabling the quick disassembly and installation of the mounting plate 7.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
