Description

Technical Field

[0001] The utility model relates to the technical field of flange processing tooling, in particular to a rapid positioning device for fine processing of plastic flanges. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used for connecting pipe ends. It is also used as flange on equipment inlet and outlet for connecting two devices. Flange made of engineering plastic is called plastic flange.

[0003] When the processing equipment is turning the flange end face, it is necessary to limit the horizontal movement of the flange to avoid the turning position error caused by the offset of the flange. For plastic flanges with a low height, it is easy to position the plastic flange itself during turning, but when the height of the plastic flange is high, such as Figure 2 The flange part 4 in the figure has an annular groove 4 on its side wall, and a number of reinforcing ribs 42 are fixedly connected to the inner wall of the annular groove 41 in an annular array, and the height of the ribs is relatively high. Before turning such plastic flanges, when the positioning device clamps and fixes such plastic flanges in the horizontal direction, if the clamping force of the positioning device on the plastic flange is too large, the plastic flange will be irreversibly deformed and damaged. If the clamping force of the positioning device on the plastic flange is small, the plastic flange will rotate and shake in the positioning device. When the tool of the turning equipment turns the unclamped flange, the tool will push the plastic flange to move, causing the plastic flange to shake and rotate, resulting in the position of the plastic flange being offset, thereby reducing the turning accuracy of the turning equipment. In view of this, we propose a rapid positioning device for finishing plastic flanges. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1 and Figure 3 As shown, one of the purposes of this embodiment is to provide a rapid positioning device for finishing plastic flanges, including a base plate 1, a plurality of vertical rods 2 are symmetrically fixedly connected to the upper surface of the base plate 1 near the edge, the upper ends of the plurality of vertical rods 2 located on the same side are fixedly connected to the end plates 3, a flange member 4 is arranged between the two end plates 3, the upper surface of one end plate 3 is fixedly connected to a fixed pad 34, the upper surface of the other end plate 3 is provided with a movable pad 35, the side of the movable pad 35 away from the fixed pad 34 is provided with a transverse clamping mechanism 6, the transverse clamping mechanism 6 is used to drive the movable pad 35 to approach or away from the fixed pad 34, and the side where the fixed pad 34 and the movable pad 35 are close to each other is provided The inner arc surface is set, and the curvature of the inner arc is the same as the arc shape of the side wall of the flange part 4. The worker places the cylindrical flange part 4 between the two end plates 3, and makes the lower end of the flange part 4 contact with the upper surface of the base plate 1. After one side of the fixed pad 34 contacts the inner arc surface of the flange part 4, the movable pad 35 is driven close to the flange part 4 through the horizontal clamping mechanism 6 until the inner arc surface of the movable pad 35 is in close contact with the other side of the flange part 4. The flange part 4 can be clamped and fixed in the predetermined position on the end plate 3. When the worker uses a turning equipment to turn the end face of the flange part 4, by limiting the horizontal movement of the flange part 4, the turning equipment can perform precise turning processing on the end face of the flange part 4.

[0028] In order to drive the movable skid 35 to move closer to or away from the fixed skid 34, the structure of the transverse clamping mechanism 6 is detailed below. Figure 3The lateral clamping mechanism 6 includes an extension rod 61 fixedly connected to one side of the movable skid 35, and a guide sleeve 62 is provided on the extension rod 61. One side of the end plate 3 located at the lower side of the movable skid 35 is fixedly connected to a side plate 65, and the guide sleeve 62 is fixedly arranged on the upper surface of the side plate 65. The guide sleeve 62 limits the sliding trajectory of the extension rod 61 so that the extension rod 61 can only move horizontally along the inner wall of the guide sleeve 62, so that the movable skid 35 can only move horizontally along a fixed path. A grip rod 64 is hinged on the upper surface of the side plate 65, and the hinge point of the grip rod 64 and the side plate 65 is located at one end of the grip rod 64. The grip rod 64 is an L-shaped structure. The end of the extension rod 61 away from the movable skid 35 is symmetrically hinged with two hinge rods 63. The other end of the hinge rod 63 is hinged at the corner of the grip rod 64. When the worker rotates the grip rod 64 upward , the grip 64 pulls one end of the hinge 63 to rotate downward, and the downwardly rotating hinge 63 pushes the extension rod 61, so that the extension rod 61 drives the movable pad 35 to move horizontally in the direction close to the fixed pad 34. When one end of the movable pad 35 contacts the side wall of the flange 4, the hinge 63 rotates to a horizontal state, and the hinge joint of the grip 64 and the side plate 65 is on the same straight line as the two ends of the hinge 63. The hinge 63 and the grip 64 are in the dead point position. At this time, the movable pad 35 is pushed in the direction close to the grip 64, and the hinge 63 and the grip 64 cannot rotate, so that the movable pad 35 cannot move horizontally, thereby locking the movable pad 35 in the position of contacting the flange 4, so that the movable pad 35 and the fixed pad 34 cooperate to clamp and fix the flange 4, which is convenient for the turning equipment to accurately turn the top of the flange 4.

[0029] When it is necessary to release the clamping fixation of the movable pad 35 on the flange part 4, the worker rotates the grip 64 clockwise, and the grip 64 pulls one end of the hinge rod 63 to rotate upward. The upward rotating hinge rod 63 pulls the extension rod 61, so that the extension rod 61 drives the movable pad 35 to move away from the fixed pad 34, and the clamping fixation of the movable pad 35 on the flange part 4 can be released.

[0030] When the tool of the turning equipment is turning the unclamped flange part 4, the tool will push the flange part 4 to move, causing the flange part 4 to rock and rotate to one side, resulting in the position of the flange part 4 being offset, reducing the turning accuracy of the turning equipment. To solve this problem, two vertical clamping mechanisms 5 are symmetrically provided near the edge of the upper surface of the end plate 3. The vertical clamping mechanism 5 is used to press the annular groove 41 downward to prevent the flange part 4 from rocking and rotating to one side. The structure of the vertical clamping mechanism 5 is detailed below. Figure 4 and Figure 5The handle 53 is rotated around the connection point of the connecting rod 54, and the end of the handle 53 close to the pressure rod 51 drives the pressure rod 51 to move forward. When the handle 53 is pressed downward, the bottom of the handle 53 engages with the V-groove on the baffle 55, and the baffle 55 prevents the handle 53 from continuing to rotate downward, and the connection between the handle 53 and the pressure rod 51 and the two ends of the connecting rod 54 are on the same straight line. At this time, the pressure rod 51, the handle 53 and the connecting rod 54 are all in the dead point position, and the reaction force applied by the annular groove 41 to the pressure rod 51 cannot cause the pressure rod 51 to rotate, thereby locking the push rod 52 in the position in contact with the inner bottom surface of the annular groove 41, so that the push rod 52 prevents the position of the flange 4 from shifting, so that the turning equipment can perform precise turning on the end face of the flange 4.

[0031] When the fixed block 34 and the movable block 35 cooperate to prevent the flange 4 from moving horizontally, and the push rod 52 cooperates with the bottom plate 1 to prevent the flange 4 from moving vertically, the worker also needs to rotate the flange 4 so that the starting turning position of the end face of the flange 4 is located directly below the tool of the turning equipment, so that the turning equipment can control the tool to perform turning processing on the end face of the flange 4. In order to facilitate the worker to rotate and adjust the position of the flange 4, the starting turning position of the end face of the flange 4 is rotated to directly below the tool. One of the reinforcing ribs 42 corresponds to the starting turning position of the end face of the flange 4 and is located at the same time on the fixed block 3 An embedded groove 31 is provided in the middle of the upper surface of the end plate 3 on the lower side of 4, and a rotating plate 32 is rotatably provided inside the embedded groove 31. A stopper 33 is fixedly connected to one side of the rotating plate 32. After the worker clamps the flange 4 between the two end plates 3, he rotates the rotating plate 32 to a vertical state. At this time, the worker rotates the flange 4 again. When the other end of the stopper 33 contacts one of the reinforcing ribs 42, the worker stops rotating the flange 4. At this time, the starting turning position of the end face of the flange 4 is located directly below the tool of the turning equipment, so that the turning equipment can accurately turn on the flange 4.
