Description

Technical Field

There are also flanges used on the inlet and outlet of equipment, which are used to connect two equipments, such as reducer flanges. Flange connection or flange joint refers to a detachable connection that is connected by flanges, gaskets and bolts as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline devices, and the inlet and outlet flanges of equipment used on equipment. There are holes on the flange, and bolts connect the two flanges tightly. Gaskets are used to seal between flanges. Flanges are divided into threaded connection (threaded connection) flanges, welding flanges and clamping flanges. Flanges are used in pairs.

[0023] The drive motor 17 is a stepper motor with a brake self-locking function, which can realize power-off self-locking. Figure 2 and Figure 3 As shown, the driving motor 17 drives the connecting rod 16 to rotate, and the connecting rod 16 drives the driving shaft 15 to make a circular motion. The driving shaft 15 is slidably connected inside the connecting block 14. When the driving shaft 15 rotates, it drives the connecting block 14 to reciprocate left and right. The connecting block 14 drives the two grinding stations 6 to realize reciprocating left and right motion through the movable plate 11, the support block 9 and the mounting plate 8. When the movable plate 11 moves to the leftmost end or the rightmost end, the end of the movable plate 11 contacts the trigger switch 13, and the driving motor 17 stops rotating. At this time, one of the two grinding stations 6 is located below the grinding head 3 to realize the grinding of the flange.

[0024] A plurality of buffer springs 18 are disposed on the left and right inner walls of the mounting seat 5, and the height of the buffer springs 18 is consistent with the height of the movable plate 11. In this embodiment, by providing the buffer springs 18, the movable plate 11 can be buffered when it hits the left and right inner walls of the mounting seat 5, so as to extend the service life of the mounting seat 5 and the movable plate 11.

[0025] Please refer to Figure 4 and Figure 5 The positioning assembly 7 includes a positioning groove 19 arranged at the upper part of the grinding station 6, an adjusting groove 23 is arranged below the positioning groove 19, a plurality of positioning pins 20 are arranged on the bottom surface of the positioning groove 19, and two positioning blocks 21 are arranged in the middle of the positioning groove 19. The bottoms of the positioning blocks 21 penetrate the bottom surface of the positioning groove 19 through through grooves and are connected to movable blocks 22. A plurality of first limiting rods 24 are horizontally penetrated inside the movable block 22, and the left and right ends of the first limiting rods 24 are installed inside the adjusting groove 23 through fixing plates 25. An adjusting block 26 with a conical cross-section is arranged between the two movable blocks 22. The upper and lower ends of the adjusting block 26 are slidably installed inside the adjusting groove 23 through second limiting rods 27.

[0027] The cross section of the positioning block 21 is semicircular. In this embodiment, the cross section of the positioning block 21 is set to be semicircular, so that the outer wall of the positioning block 21 has a larger contact surface with the flange center hole, increasing the friction between the outer wall and the inner wall of the flange center hole, and preventing the positioning block 21 from causing damage to the flange center hole.

[0028] Compression springs 29 are sleeved on the left and right outer walls of the first limit rod 24. In this embodiment, when the adjustment block 26 moves forward, the two movable blocks 22 drive the positioning blocks 21 to move toward each other under the action of the compression springs 29, making it easy for operators to remove the flange.

[0033] The following lists the preferred embodiments of the flange finishing grinder production and processing equipment to clearly illustrate the content of the present invention. It should be clear that the content of the present invention is not limited to the following embodiments, and other improvements through conventional technical means of ordinary technicians in this field are also within the scope of the concept of the present invention.

[0034] The embodiment of the present invention provides a flange finishing method, comprising the following steps:

[0035] ① Place the two flanges in the positioning grooves 19 of the two grinding stations 6 respectively, position the flanges through the positioning pins 20, and then rotate the adjusting screw 28 through the positioning rod 35. Using the screw principle, move the adjusting block 26 backward, push the two movable blocks 22 outward to both sides, so that the two movable blocks 22 respectively drive the positioning blocks 21 to move outward, clamp the center hole of the flange, realize the positioning and clamping of the flange, and avoid the flange from being offset during processing;

[0036] ② After the flange is positioned, the switch of the driving motor 17 is turned on, and the driving motor 17 drives the connecting rod 16 to rotate, and the connecting rod 16 drives the driving shaft 15 to make a circular motion. The driving shaft 15 is slidably connected inside the connecting block 14. When the driving shaft 15 rotates, it drives the connecting block 14 to reciprocate left and right. The connecting block 14 drives the two grinding stations 6 to reciprocate left and right through the movable plate 11, the support block 9 and the mounting plate 8. When the movable plate 11 moves to the leftmost end or the rightmost end, the end of the movable plate 11 contacts the trigger switch 13, and the driving motor 17 stops rotating. At this time, one of the two grinding stations 6 is located below the grinding head 3, and the flange grinding work is realized;

[0037] ③ After the grinding is completed, turn on the drive motor 17 switch, and drive another grinding station 6 to move to the bottom of the grinding head 3 through the transmission structure to process another flange. At the same time, the flange that has been ground can be removed and the flange to be processed can be installed to ensure the continuity of the processing.

[0038] In summary, the present invention has the following advantages:

[0039] (1) A bilateral rotating working mechanism is adopted, wherein the two grinding stations 6 can respectively place and remove the flange. When one grinding station 6 is performing the grinding operation, the other grinding station 6 places the component. After the component is ground, the driving motor 17 and the transmission structure drive the grinding station 6 to reciprocate, so that the grinding station 6 that has completed the flange placement is sent to the bottom of the grinding head 3 for continuous processing, so that the processing efficiency of the grinding machine can be greatly improved;

[0040] (2) A positioning assembly 7 that is easy to operate is provided to position and clamp the flange, and the lifting rod 32 can be driven by the hand lever 33 to lift the flange, so that the flange can be easily removed, thereby improving the installation and removal efficiency of the flange.
