Description

Elbow automatic welding groove processing equipment and processing method

Technical field

The present application relates to the field of local cutting technology, and in particular to an automatic welding groove processing equipment and processing method for elbows.

Background technique

During the installation of a nuclear power island, process pipes with a diameter of 60.3-168.3mm and a thickness of ≤10mm accounted for 69.6% of the total installed butt welds, and 79.2% of the welds in this part were butt welds between elbows and pipe fittings. At present, most of this part of the process pipeline is completed by manual welding, and a small part is completed by manual welding and automatic welding filling and covering. In order to cope with the shortage of highly skilled welder resources, this part of the process pipeline tends to be fully welded. Automatic welding is completed.

Most of the manual welding grooves of elbows are processed by flame cutting, manual grinding with a grinder, or external bevel lathe turning. The surface accuracy of the processed manual welding grooves of elbows is low, and after docking with the pipe group There is a large internal offset deviation, which cannot meet the assembly requirements of good automatic welding groove size consistency, assembly gap and internal offset amount tending to 0. If manual welding groove is used for automatic bottom welding, the bottom layer weld bead is prone to defects such as burn-through, weld bead, lack of penetration or lack of fusion. Therefore, the processing quality and processing accuracy of automatic welding grooves have become the key to ensuring the quality of on-site welding.

However, the mainstream elbow beveling machines in the existing technology are not ideal because it is difficult to achieve the fixing and centering operations of the elbow, especially the fixing and centering operations of the elbows at different angles. If the axis of the port where the elbow is machined is not axial with the axis of the rotation system, deviation of the groove will occur. Although CNC machine tools can process elbow grooves to meet the requirements for groove size, the processing cost is high and the requirements for workers are high, which is not conducive to on-site promotion and application.

Therefore, there is still room for improvement for existing elbow beveling machines.

Each clamping member includes a first clamping member 110 and a second clamping member 120 with opening directions of the clamping recesses facing each other. The first clamping member 110 is configured to be close to the second clamping member 120 to clamp together. Elbow 700. In the embodiment, the first adjustment mechanism 200 is connected to the positioning mechanism 100, and the first adjustment mechanism 200 is used to adjust the position of the positioning mechanism 100 in the first horizontal direction F1. In the embodiment, the second adjustment mechanism 400 is connected to the cutting mechanism 300, and the second adjustment mechanism 400 is used to adjust the position of the cutting mechanism 300 in the vertical direction.

In the embodiment, the cutting mechanism 300 is used to cut the elbow 700 to process the automatic welding groove of the elbow 700 . The cutting and positioning mechanisms 100 are spaced apart. The cutting mechanism 300 includes a cutterhead 310 and a cutter head that is detachably disposed on the cutterhead 310 . The distance measurement component is used to measure the distance between the position of the distance measurement component and the end face of the elbow 700; the cutter head 310 is configured to be rotatable to adjust the position of the distance measurement component.

In this way, according to the automatic elbow welding and groove processing equipment provided by the embodiment of the present application, the first clamping member 110 and the second clamping member 120 can clamp the elbow 700 from opposite sides of the elbow 700, Since both the first clamping member 110 and the second clamping member 120 have at least two parts that are in contact with the outside of the elbow 700 , at least four parts are in contact with the outside of the elbow 700 . Because three points that are not on the same straight line determine a plane, the elbow 700 is positioned by at least four parts mentioned above, so that the elbow 700 is stably clamped and positioned, thereby achieving a relatively effective fixation of the elbow 700 .

In the embodiment, the numerical values at four positions on the upper, lower, left, and right positions of the distance-measuring member provided on the cutterhead 310 of the cutting mechanism 300 and the outer wall outside the end surface of the elbow 700 are measured, and are recorded as the first numerical value and the third numerical value respectively. Second value, third value and fourth value. On this basis, adjust the position of the elbow 700 relative to the cutting mechanism 300 in the first horizontal direction F1 and the position relative to the cutting mechanism 300 in the vertical direction, that is, the position of the elbow 700 in the horizontal plane, so that the first The first numerical value and the second numerical value are within the predetermined tolerance range, and the third numerical value and the fourth numerical value are within the predetermined tolerance range, thereby ensuring the concentricity between the circumferential direction of the end face of the elbow 700 and the cutterhead 310, which is conducive to the realization of the elbow. 700 and cutterhead 310 centering.

In the embodiment, as an example, the distance measuring member may be, for example, a dial indicator, and the above measurement is performed through the contact of the dial indicator with the end surface of the elbow 700 . In other examples, the distance measuring component may also be, for example, a distance measuring laser, which performs the above measurement in a non-contact manner.

It should be noted that the above-mentioned first numerical value and the second numerical value also include the situation that they are equal within the predetermined tolerance range. Similarly, the above-mentioned third numerical value and the fourth numerical value also include the situation that the two are equal within the predetermined tolerance range.

In embodiments, the "opening direction" of the clamping recess should be understood to include the following meaning, that is, the clamping recess has an opening that communicates the external environment with the internal space defined by the clamping recess, and the direction in which the opening faces is the clamping recess. The opening direction of the recess.

In embodiments, by utilizing the clamping recess, the inner space defined by the clamping recess can also be used to accommodate the outer portion of the elbow 700 , thereby making the positioning of the elbow 700 more reliable.

In the embodiment, the cutterhead 310 of the cutting mechanism 300 is a rotatable structure, on which not only the above-mentioned distance measuring member can be detachably installed (for example, detachably installed through bolts), but also the tool for processing the elbow 700 can be detachably installed. When the cutterhead 310 rotates, the automatic welding groove tool drives the cutter to rotate around the axis of the cutterhead 310, thereby cutting the elbow 700.

In this embodiment, the rotation of the cutterhead 310 can be achieved by the drive motor 320 in the cutting mechanism 300 and the reducer arranged in the cutting mechanism 300 before the drive motor 320 and the cutterhead 310 , which will not be described again.

In embodiments, as an example, the first horizontal direction F1 and the second horizontal direction F2 may be perpendicular to each other, where the first horizontal direction F1 may be defined as the X-axis direction, and the vertical direction may be defined as the Y-axis direction.

According to the automatic elbow welding and groove processing equipment provided by the embodiment of the present application, the first adjustment mechanism 200 may include a first adjustment component 200a and a second adjustment component 200b that are connected to each other. The first adjustment component 200a may be connected to the positioning mechanism 100, The first adjustment component 200a may be used to drive the positioning mechanism 100 to rotate around an axis extending in the vertical direction (ie, the C-axis below), which passes through the positioning mechanism 100.

In an embodiment, the second adjustment assembly 200b may be a slide plate assembly used to adjust the position of the positioning mechanism 100 in the first horizontal direction F1, and the slide plate assembly may be an existing structure. The first adjustment component 200a may include a rotating disk 610 with indexing, which may also be an existing structure, as shown in FIGS. 1 and 2 , where the above-mentioned axis provided by the first adjustment component 200a may be defined as the C-axis (in FIG. 1 and represented by the letter C in FIG. 2 ), here, the C axis may be the center of the rotating disk 610 , that is, the axis of the rotating disk 610 . Therefore, the first adjustment assembly 200a is formed as essentially a C-axis adjustment assembly.

In embodiments, providing the first adjustment component 200a further facilitates adjusting the posture of the elbow 700 in space, thereby facilitating the fixing and centering operations of the elbow 700.

According to the automatic elbow welding and groove processing equipment provided by the embodiment of the present application, the positioning mechanism 100 may include a fixed component and a moving component. Specifically, the fixing member may be connected with the first adjustment mechanism 200 (for example, with the first adjustment component 200a of the first adjustment mechanism 200), and the second clamping member 120 is fixedly disposed on the fixing member. In embodiments, the fixing member may be formed as a seat member with a stepped structure, which may be provided, for example, on the upper end surface of the rotating disk 610 of the first adjustment assembly 200a, so as to be able to rotate along with the rotating disk 610.

In an embodiment, the movement assembly may include a connecting member and a guide member 210. The guide member 210 may be disposed on the fixed member. The guide member 210 may have a first guide portion extending along a vertical direction. The connecting member may have a first guide portion extending along a vertical direction. The second guide part extends in the direction, one of the first guide part and the second guide part is passed through the other of the first guide part and the second guide part, the first guide part and the second guide part The guide part is movably fitted along the vertical direction.

In an embodiment, the first guide part may be, for example, a rod part, and the second guide part may be, for example, a hole part. That is to say, the connecting member may be provided with a hole part, through which the connecting member may be sleeved on the third The outer side of the rod portion of a guide portion uses the sliding fit of the hole portion and the rod portion to guide the movement of the connecting member relative to the first guide portion, so that the connecting member moves along the vertical direction, thereby helping to ensure the movement of the connecting member stability and accuracy.

In an embodiment, the second clamping member 120 is disposed on the fixed member, for example, may be disposed on the upper surface of the fixed member, so that the elbow 700 may be placed on the second clamping member 120, and then the first clamping member 110 clamps the elbow 700 close to the second clamping member 120. The advantage of this arrangement is that the gravity of the elbow 700 itself will promote the elbow 700 and the second clamping member 120 to form a relatively stable fit, that is, even if When the elbow 700 is placed on the second clamping member 120 without being contacted by the first clamping member 110, it can also reach a balanced state due to its own gravity. This eliminates the need to consider the downward movement tendency of the elbow 700 caused by its own gravity during the positioning process, which makes the positioning of the elbow 700 difficult and adversely affects the accuracy of the positioning.

In an embodiment, the guide member 210 may have a head that can be grasped by the operator and the above-mentioned rod part for applying force, wherein the end of the above-mentioned rod part may be provided with an external thread, so that the upper end surface of the fixing member can be An internal threaded hole is provided on the upper body to screw the guide member 210 onto the fixed member.

In an embodiment, the connecting member may be in a strip shape, and one end in the extending direction may be provided with the above-mentioned hole. As mentioned above, the hole is sleeved on the outside of the rod part of the guide member 210 so as to be able to move relative to the guide member 210 . The 210's stem slides.

According to the automatic elbow welding and groove processing equipment provided by the embodiment of the present application, the motion component may also include a rod member, a force applying member and a reset member. In embodiments, the rod member may be passed through the connecting member, the rod member may be disposed on the fixing member, and the rod member may have an external threaded portion.

In an embodiment, the force-applying member may abut an upper side of the connecting member facing away from the fixing member, the force-applying member may have an internal thread portion, and the force-applying member may be sleeved via a screw fit of the internal thread portion and the external thread portion. to the rod member. In embodiments, the reset member may be located between the connection member and the fixation member, the reset member may abut the lower side of the connection member and the upper side of the fixation member, and the reset member may be configured to be a distance between the connection member and the fixation member Stores elastic potential energy as it decreases.

In this way, in an embodiment, the force-applying member can be screwed so that the force-applying member moves along the rod member, for example, moves downward along the rod member, thereby causing the force-applying member to move downward against the connecting member, thereby making the connection The first clamping member 110 of the connecting member also moves downward to cooperate with the second clamping member 120 to clamp and position the elbow 700 .

In an embodiment, since the reset member stores elastic potential energy when the distance between the connecting member and the fixed member is reduced, the reset member can continuously exert an upward force on the connecting member. Once the force-exerting member is screwed, the force-exerting member moves along the rod member. By moving upward, the connecting member can move upward via the force exerted by the reset member, thereby resetting. As an example, in embodiments, the return member may be, for example, a coil spring sleeved on the outside of the rod member.

In embodiments, as an example, the force-applying member may be, for example, the adjusting nut 220, and the rod member may be, for example, a screw rod. In embodiments, the connecting member may be provided with a waist-shaped hole along the extending direction of the connecting member, and the screw rod may be inserted into the waist-shaped hole.

According to the automatic elbow welding groove processing equipment provided by the embodiment of the present application, the clamping recess may include a first positioning plane 111 and a second positioning plane 112 connected to each other, and the first positioning plane 111 may intersect with the second positioning plane 112, Specifically, the angle between the first positioning plane 111 and the second positioning plane 112 may be, for example, an obtuse angle. The first positioning plane 111 may have a first position for contacting the outside of the elbow 700 . Plane 112 may have a second position for abutting the outside of elbow 700 .

In the embodiment, the first positioning plane 111 and the second positioning plane 112 intersect to form an essentially angular structure. When the clamping recess formed by the angular structure abuts against the outside of the elbow 700, due to the bend The outer contour of 700 presents a circular shape, and both the first positioning plane 111 and the second positioning plane 112 are tangent to the circular outer contour. That is, the first positioning plane 111 is tangent to the outer contour of the elbow 700 at the first position, and the second positioning plane 112 is tangent to the outer contour of the elbow 700 at the second position.

The advantage of the first positioning plane 111 and the second positioning plane 112 is that when the first positioning plane 111 and the second positioning plane 112 both abut against the outside of the elbow 700 , the outside of the elbow 700 is naturally in contact with the first positioning plane. 111 is tangent to the second positioning plane 112. This tangency makes the center of the elbow 700 pass through the angular structure formed by the first positioning plane 111 and the second positioning plane 112 when viewed along the axial direction of the elbow 700. Angular bisector. Therefore, this positioning method facilitates accurate positioning of the elbow 700 and facilitates subsequent centering operations.

Since the first clamping member 110 and the second clamping member 120 have the same structure, when the first clamping member 110 and the second clamping member 120 cooperate with each other, the outside of the elbow 700 is in contact with the two first positioning planes. 111 and the two second positioning planes 112 have four tangent positions. These four positions are not on the same straight line and can determine a plane. That is to say, using the first positioning plane 111 and the second positioning plane 112 to form the clamping recess ensures that the second clamping member 120 can pass through the two positions provided by the second clamping member 120 when supporting the elbow 700 alone. To stably support the elbow 700 and achieve preliminary positioning, and to ensure effective clamping and positioning of the elbow 700 when mated with the first clamping member 110 .

The clamping members 120 are spaced apart along the extension direction of the elbow 700 . In this way, it is helpful to further improve the reliability of positioning of the elbow 700. As an example, in the embodiment, the plurality of clamping members may include two pairs of first clamping members 110 and second clamping members 120. A clamping member 110 and a second clamping member 120 may be clamped at two ends of the elbow 700 respectively.

The automatic elbow welding groove processing equipment provided according to the embodiment of the present application may also include a cross backing plate 380. The cross backing plate 380 may be detachably provided on the cutterhead 310. The cross backing plate 380 may be used with the end face of the elbow 700.
