Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding, and particularly relates to a welding equipment for heliostat assembly production. BACKGROUND

[0002] As the core light-concentrating unit of a photo-thermal power generation system, the precision and reliability of a heliostat directly relate to the overall power generation efficiency of the system. The rotating seat and the annular disc are key components of the center disc of the heliostat, and the connection between the two is usually achieved by welding. The rotating seat is the pivot connecting the mirror frame and the driving mechanism (such as a column and a tracking device), and the annular disc is the basis of the mirror surface support structure. Therefore, the welding quality between the rotating seat and the annular disc has a decisive influence on the tracking precision, structural stability and service life of the heliostat.

[0003] At present, the welding production of the rotating seat and the annular disc in the industry generally adopts an operation mode based on a special welding tool. The traditional process mainly includes the following steps: 1. manual feeding, the operator needs to manually carry the rotating seat and the annular disc to be welded to the welding station; 2. manual clamping and positioning, the operator needs to manually place and position the annular disc and the rotating seat on the special welding tool designed and manufactured in advance. In this process, the operator needs to rely on experience and visual observation to adjust the two workpieces to the relative position set by the tool, and then fix them through the clamping mechanism (such as clamping jaws, pressing plates, bolts, etc.) on the tool; 3. manual welding, the operator operates the welding gun to weld around the joint between the rotating seat and the annular disc, which also depends on the skill level and stability of the welder.

[0004] However, this traditional production method based on manual operation and special tool highly depends on manual operation, and the core links such as feeding, clamping and positioning, and welding need to be completed by skilled workers, which is labor-intensive, low in production efficiency, easily affected by the state of the personnel, and cannot guarantee the welding quality. Therefore, how to significantly reduce the dependence on manual operation and improve the production efficiency while ensuring or even improving the welding quality has become a key technical problem to be solved in the welding production of the center disc of the heliostat.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1:

[0028] like Figure 8 The diagram illustrates a structural example of a heliostat center disk, comprising a rotating base 11 and an annular disk 51. The rotating base 11 includes a pair of parallel support plates 111. Each support plate 111 has an inclined surface on its sides above the middle in the height direction, curving inwards towards its centerline. The opposing sides of the two support plates 111 are connected by a mounting rod 112, which is perpendicular to the support plates 111 and whose axis intersects the centerline of the support plates 111. The bottom surfaces of the two support plates 111 are coplanar, serving to abut against the surface of the annular disk 51 for welding connection. After the rotating base 11 is connected to the annular disk 51, the axis of the annular disk 51 passes perpendicularly through the axis of the mounting rod 112, and the central hole of the annular disk 51 is located at the exact center of the two support plates 111.

[0029] This application provides a welding device for producing heliostat components, used to... Figure 8 The rotating seat 11 shown is welded to the top surface of the annular disk 51.

[0030] Specifically, such as Figures 1-6 As shown, the welding equipment in this example includes: a rectangular cylinder 1, two pairs of stop bars 2, a positioning round bar 3, a rotating rod 4, a conveying track 5, and a welding mechanism 6.

[0031] Among them, such as Figure 3 and Figure 6 As shown, a rectangular tube 1 is vertically and vertically continuous, used to stack rotating seats 11. The length of the rotating seat 11 is equal to the distance between the left and right inner sides of the rectangular tube 1, that is, the distance between the two opposite sides of the two support plates 111 is equal to the distance between the left and right inner sides of the rectangular tube 1. When the rotating seat 11 is filled, the opposite sides of the two support plates 111 are always in sliding contact with the left and right inner sides of the rectangular tube 1 respectively. The width of the rotating seat 11 is equal to the distance between the front and rear inner sides of the rectangular tube 1, that is, the distance between the left and right end faces of the support plates 111 is equal to the distance between the front and rear inner sides of the rectangular tube 1. When the rotating seat 11 is filled, the left and right end faces of the two support plates 111 are always in sliding contact with the front and rear inner sides of the rectangular tube 1 respectively.

[0032] like Figures 1-4 As shown, two pairs of stop rods 2 are slidably inserted through the lower ends of the front and rear sides of the rectangular tube 1; when one end of the stop rod 2 is located inside the rectangular tube 1, the stop rod 2 is used to support the rotating seat 11, and at this time, multiple rotating seats 11 can be vertically filled into the rectangular tube 1 in sequence.

[0033] like Figures 3-6 As shown, the positioning rod 3 is vertically positioned directly below the rectangular tube 1 and moves along its own axis. Its diameter is equal to the diameter of the central hole of the annular disk 51. The upper end of the positioning rod 3 has a vertically oriented conical structure, and its top surface is a horizontal frustum. A placement groove 31 is vertically downward opened on the top surface of the positioning rod 3. The placement groove 31 is arranged radially along the horizontal frustum and along the length of the rectangular tube 1, and its two ends are connected to the conical surface at the upper end of the positioning rod 3. Here, the length direction of the rectangular tube 1 refers to the direction perpendicular to the left and right sides of the rectangular tube 1. Correspondingly, the width direction of the rectangular tube 1 refers to the direction perpendicular to the front and rear sides of the rectangular tube 1. During the process of the positioning rod 3 moving from below the rectangular tube 1 to its upper end extending into the rectangular tube 1 to a predetermined length, the positioning rod 3 is used to separate the two sets of stop bars 2 until their opposite end faces are located inside the corresponding front and rear inner sides of the rectangular tube 1.

[0034] like Figure 3 and Figure 4As shown, the rotating rod 4 is horizontally positioned on the top surface of the positioning rod 3; one end of the rotating rod 4 is located outside the placement groove 31 and is rotatably connected to the top surface of the positioning rod 3, and its rotation axis is vertically set; the bottom surface of the rotating rod 4 abuts against the top surface of the positioning rod 3; the length of the rotating rod 4 is greater than the distance between one end of it and the placement groove 31.

[0035] like Figure 1 As shown, the conveying track 5 is located below the rectangular cylinder 1, and its conveying direction is consistent with the width direction of the rectangular cylinder 1. It is used to convey the horizontal annular disk 51. The axis of the annular disk 51 is located in the middle of the left and right sides of the rectangular cylinder 1.

[0036] like Figure 6 As shown, the welding mechanism 6 includes two sets of welding torches 61 mounted below the rectangular tube 1 and located at predetermined distances on the left and right sides of the rectangular tube 1, respectively. The welding torches 61 are moved along the width direction of the rectangular tube 1.

[0037] The working principle of the welding equipment will be explained below in conjunction with the above structure:

[0038] Preparation stage: such as Figures 1-6 As shown, the positioning rod 3 descends below the rectangular cylinder 1 to avoid obstructing the path of the conveying track 5 for conveying multiple annular discs 51. The two pairs of stop rods 2 extend into the rectangular cylinder 1 at opposite ends. The stop rods 2 can support the rotating seats 11. At this time, multiple rotating seats 11 can be vertically filled into the rectangular cylinder 1 in sequence by manual or automatic filling equipment, thus completing the preparation stage.

[0039] Material extraction stage: such as Figures 1-6As shown, after the conveying track 5 conveys the to-be-welded annular disc 51 to the lower side of the rectangular cylinder 1, the conveying track 5 stops conveying, and due to the precision limitation of the conveying track 5, the axis of the to-be-welded annular disc 51 can not be completely located in the middle of the rectangular cylinder 1; then the positioning round rod 3 moves upward, and the upper end thereof penetrates into the center hole of the to-be-welded annular disc 51, and due to the conical surface structure of the upper end of the positioning round rod 3, in the process of upward movement of the positioning round rod 3, the conical surface will abut against the edge of the center hole of the annular disc 51 and generate a radial force, and the annular disc 51 will slide along the conical surface under the action of the radial force until the axis of the center hole of the annular disc 51 coincides with the axis of the positioning round rod 3, and at this time, the positioning of the to-be-welded annular disc 51 is completed; when the positioning round rod 3 moves upward to a position where the upper end thereof extends into the rectangular cylinder 1 by a predetermined length, the opposite end faces of the two pairs of blocking rods 2 are separated to be coplanar with the front and rear inner side faces of the rectangular cylinder 1, and at the same time, the mounting rod 112 of the lowermost rotating seat 11 is away from the placing groove 31 by a small distance, and due to the absence of the support of the blocking rods 2, the rotating seat 11 in the rectangular cylinder 1 falls vertically, so that the mounting rod 112 of the lowermost rotating seat 11 enters the placing groove 31, and the left and right end faces of the support plate 111 of the lowermost rotating seat 11 block the paths of the blocking rods 2 into the rectangular cylinder 1; the rotating rod 4 rotates to a position where the other end thereof is located above the placing groove 31, so as to lock the mounting rod 112 in the placing groove 31, and at this time, the taking of the rotating seat 11 is completed.

[0040] Positioning and clamping stage: as shown in Figures 1-6 , the positioning round rod 3 moves downward, and the rotating seat 11 in the rectangular cylinder 1 moves downward synchronously with the positioning round rod 3, as shown in Figure 3 , due to the structure of the support plate 111, there is a space between the left and right ends of the upper and lower adjacent support plates 111, which can accommodate the blocking rods 2, and when the positioning round rod 3 drives the lowermost rotating seat 11 to move downward to a position where the blocking rods 2 are located between the inclined surface of the support plate 111 of the lowermost rotating seat 11 and the bottom surface of the support plate 111 of the adjacent rotating seat 11, the two pairs of blocking rods 2 move towards each other, and the opposite ends thereof extend into the rectangular cylinder 1, and the upper rotating seat 11 abuts against the blocking rods 2, so as to realize the separation of the lowermost rotating seat 11 and the upper rotating seat 11, and the positioning round rod 3 only drives the lowermost rotating seat 11 to move out of the rectangular cylinder 1 until the positioning round rod 3 moves downward to a position where the bottom surface of the support plate 111 of the rotating seat 11 abuts against the annular disc 51, and then the welding gun 61 moves along the joint between the bottom surface of the support plate 111 and the annular disc 51 to weld the support plate 111 and the annular disc 51. After the welding is completed, the rotating rod 4 rotates out of the upper side of the placing groove 31, the positioning round rod 3 moves downward and moves out of the center hole of the corresponding annular disc 51, and the conveying track 5 continues to run to convey the welded rotating seat 11 and the annular disc 51 to the next process, and at the same time, the next to-be-welded annular disc 51 is conveyed to the lower side of the rectangular cylinder 1, and the above operation is repeated to realize the continuous welding of the rotating seat 11 and the annular disc 51.

[0041] The structure of the positioning round rod 3 is arranged, and the structure of the annular disc 51 is fully utilized, so that the positioning round rod 3 can position the annular disc 51 to be welded when moving up, the influence of the conveying track 5 on the positioning precision of the annular disc 51 to be welded is eliminated, and the automation degree of positioning of the annular disc 51 to be welded is effectively improved, so as to improve the welding quality and efficiency; meanwhile, through cooperation of the positioning round rod 3 and the blocking rod 2, the two pairs of blocking rods 2 can be separated synchronously in the up-moving process of the positioning round rod 3, so that the positioning round rod 3 can complete the material taking of the rotating seat 11 under the action of the placing groove 31 and the rotating rod 4, and the automation degree of the welding equipment is further improved; in addition, under cooperation of the structure of the supporting plate 111 and the blocking rod 2, the annular disc 11 to be welded can be automatically separated from other annular discs 11 above, the reliability and automation degree are high, and the production efficiency of the central disc of the heliostat can be effectively improved.

[0042] Specifically, the welding mechanism in the welding equipment of the embodiment is two groups of welding guns 61 arranged at a predetermined distance on the left and right sides of the rectangular cylinder 1, and two groups of linear lead screws are adopted, and the two groups of welding guns 61 are installed on the movable parts of the linear lead screws, so that the welding guns 61 can stably weld along the joint lines between the supporting plates 111 and the top surface of the annular disc 51 on the opposite sides, and the supporting plates 111 and the top surface of the annular disc 51 are not welded on all joint lines, and correspondingly, the welding guns 61 for welding other joint lines can be arranged on the material discharge path of the supporting plates 111 and the annular disc 51 after temporary welding. The advantage of this arrangement is that when only one joint line is welded, the local structure formed by the welded supporting plate 111 and the annular disc 51 has low rigidity, and the thermal stress and deformation generated by welding mainly concentrates in this local area. When discharging, this local deformation can relatively freely occur and partially release without interference from subsequent welding heat input. If all joint lines are welded at one time, the rigidity of the whole structure will rapidly increase, the stress generated by welding cannot be freely released, and will be superimposed and restrained in the structure, which may cause complex and unpredictable deformation of the whole structure, thereby affecting the welding precision. Meanwhile, when only one joint line is welded, the welding gun 61 is easier to approach the weld with the best angle and position, reduces the welding dead angle, ensures the penetration and forming quality of the joint line, and after discharging, the welding of other joint lines is not interfered by other structural members.

[0043] Preferably, the conical surface at the upper end of the positioning round rod 3 can be made of wear-resistant material, for example, a layer of hard chromium is plated on the conical surface, and the conical surface is polished. In actual production, the edge of the center hole of the annular disc 51 is chamfered to avoid wear between the conical surface and the edge of the center hole of the annular disc 51, thereby affecting the positioning precision.

[0044] Preferably, as shown in FIG. 6, the annular disc 51 to be welded is placed on the rotating seat 11, and the rotating seat 11 is rotated to a position where the annular disc 51 to be welded is aligned with the positioning round rod 3, and then the positioning round rod 3 is moved up to position the annular disc 51 to be welded. Figure 1 and Figure 6As shown, the conveying track 5 can adopt a pair of guide rails 52 towards the width direction of the rectangular tube 1, both guide rails 52 are located below the left and right sides of the rectangular tube 1 and at the same horizontal height; both guide rails 52 are in the form of grooves, and the grooves are oppositely arranged along the length direction of the rectangular tube 1, the edge of the annular disc 51 is movably fitted in the grooves of both guide rails 52, and the axis of the central hole of the annular disc 51 is always located in the middle of the left and right sides of the rectangular tube 1. The conveying track 5 further comprises two rows of roller groups arranged along the length direction of the guide rail 52, both rows of roller groups are located below one side of the corresponding guide rail 52, and the rotation axes of the rollers in each roller group are arranged along the length direction of the rectangular tube 1, for conveying the annular disc 51 along the length direction of the guide rail 52. The advantage of setting two rows of roller groups for conveying is that the roller groups only contact the edge of the annular disc 51, the central hole of the annular disc 51 is not blocked, and the positioning round rod 3 can enter the central hole of the annular disc 51 without interference, further improving the reliability of the welding equipment.

[0045] Specifically, as shown in Figures 3-5 The positioning round rod 3 is in a two-segment structure, one segment is a conical shell 32, the small end of which is a horizontal circular table, and the large end is an open end; the other segment is a main round rod 33, the large end of the conical shell 32 is coaxially and detachably connected with the upper end of the main round rod 33. The connection between the large end of the conical shell 32 and the upper end of the main round rod 33 can be achieved by screwing, that is, internal threads are processed on the inner wall of the large end of the conical shell 32, and external threads are processed on the upper end of the main round rod 33. When the large end of the conical shell 32 is screwed with the upper end of the main round rod 33, the outer edge of the large end of the conical shell 32 is connected with the outer edge of the main round rod 33, and the screwing precision is high, which can effectively ensure the coaxiality of the two. In addition, the detachable connection can also be achieved by using an annular clamping groove structure, that is, an annular groove is coaxially formed on the outer edge of the upper end of the main round rod 33, and a locking block is arranged on the inner wall of the large end of the conical shell 32. After the large end of the conical shell 32 is connected with the upper end of the main round rod 33, the conical shell 32 can be rotated, and the locking block can be rotated into the annular groove, thereby achieving detachable connection.

[0046] Specifically, a motor 34 is arranged in the conical shell 32, which is fixed to the bottom surface of the horizontal circular table outside the placement groove 31 by bolts, and the driving end of the motor 34 vertically penetrates the horizontal circular table and is connected to one end of the rotating rod 4. The structure of the conical shell 32 facilitates the maintenance of the motor 34.

[0047] Embodiment 2:

[0048] As a further embodiment of the above embodiment 1, as shown in Figures 3-7As shown in the drawings, the stopper rods 2 are arranged perpendicularly to the front and back sides of the rectangular cylinder 1, and the axes of the four stopper rods 2 are arranged on the same horizontal plane, and the outer edges of the two stopper rods 2 on the same side are tangent to the left and right inner sides of the rectangular cylinder 1 respectively; the other ends of the two stopper rods 2 on the same side, i.e. the ends outside the rectangular cylinder 1, are connected by a strip-shaped plate 21 parallel to the front and back sides of the rectangular cylinder 1, and the lower part of the strip-shaped plate 21 is connected with a mounting frame 22 inclined towards the upper end of the positioning round rod 3 and located in the middle of the two stopper rods 2, and the end of the mounting frame 22 is located below the rectangular cylinder 1 and is rotatably provided with a guide wheel 23, and the rotating axis of the guide wheel 23 is horizontal and perpendicular to the axis of the stopper rod 2; a spring 24 is sleeved on the stopper rod 2 and is connected between the corresponding front and back outer sides of the rectangular cylinder 1 and the corresponding strip-shaped plate 21; when the spring 24 is in the natural state, the opposite ends of the two pairs of stopper rods 2 extend into the rectangular cylinder 1, the distance between the two guide wheels 23 is smaller than the diameter of the positioning round rod 3 and larger than the size of the position on the rotating seat 11 which needs to pass vertically between the two guide wheels 23, i.e. larger than the diameter of the mounting rod 112.

[0049] As shown in the drawings, Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown in the drawings, when the positioning round rod 3 moves upwards, the conical surface of the positioning round rod 3 will abut against the guide wheel 23 and make the guide wheel 23 slide downwards along the conical surface of the positioning round rod 3, and the conical surface gives the guide wheel 23 a radial component force, and the component force is transmitted to the stopper rod 2 through the mounting frame 22 and the strip-shaped plate 21, so as to separate the two pairs of stopper rods 2 and stretch the spring 24; when the upper end of the positioning round rod 3 extends out of the rectangular cylinder 1 by a predetermined length, the opposite end surfaces of the two pairs of stopper rods 2 are separated to be coplanar with the corresponding front and back inner sides of the rectangular cylinder 1, and the rotating seat 11 falls down, and the left and right end surfaces of the support plate 111 of the lowermost rotating seat 11 block the paths of the stopper rods 2 into the rectangular cylinder 1 respectively; the positioning round rod 3 drives the lowermost rotating seat 11 to move downwards through the placement groove 31 and the rotating rod 4, and the upper rotating seats 11 move downwards synchronously; when the stopper rod 2 is located between the inclined surface of the support plate 111 of the lowermost rotating seat 11 and the bottom surface of the support plate 111 of the adjacent rotating seat 11, the stopper rod 2 is no longer blocked, and the opposite ends of the two pairs of stopper rods 2 will pop into the rectangular cylinder 1 under the action of the spring 24, so as to realize the separation of the lowermost rotating seat 11 and the other rotating seats 11; through the cooperation of the guide wheel 23 and the conical surface of the positioning round rod 3 and under the action of the spring 24, the stopper rod 2 can automatically realize the separation of the rotating seat 11 to be welded and the other rotating seats 11 with the movement of the rotating seat 11, so as to improve the material taking efficiency of the rotating seat 11, and the spring 24 makes the stopper rod 2 have a faster rebound speed, so that the separation is fast and complete, and the positioning round rod 3 can realize material taking with a faster moving speed, which further improves the welding efficiency and reliability of the welding equipment.

[0050] Example 3:

[0051] As a further embodiment of the above-mentioned embodiment 1 or 2, as shown in the drawings, Figure 1 ,Figure 2 、 Figure 6 As shown in the figure, the lower part of the left and right sides of the rectangular cylinder 1 is provided with a limiting plate 12 in parallel, the limiting plate 12 is arranged along the length direction of the rectangular cylinder 1, a pair of limiting strips 13 vertically arranged on the opposite side of the two limiting plates 12 and communicated to the upper and lower ends of the limiting plate 12, the distance between the bottom surface of the limiting plate 12 and the annular disc 51 is less than the height of the rotating seat 11; when the opposite side of the two limiting plates 12 abuts against the corresponding stop rod 2, the opposite side of the two limiting plates 12 is coplanar with the corresponding left and right inner side of the rectangular cylinder 1 respectively, and the opposite side of the two limiting strips 13 on the limiting plate 12 is coplanar with the corresponding front and rear inner side of the rectangular cylinder 1.

[0052] In application, the two limiting plates 12 are close to each other and abut against the corresponding stop rod 2, at this time, the opposite side of the two limiting plates 12 is coplanar with the corresponding left and right inner side of the rectangular cylinder 1 respectively, and the opposite side of the two limiting strips 13 on the limiting plate 12 is coplanar with the corresponding front and rear inner side of the rectangular cylinder 1; the positioning round rod 3 is moved up to be connected with the rotating rod 4 and the mounting rod 112 of the lowermost rotating seat 11 through the placing groove 31, the positioning round rod 3 drives the lowermost rotating seat 11 to move down, the opposite side of the two supporting plates 111 abuts against the left and right inner side of the rectangular cylinder 1 respectively, and is converted to abut against the opposite side of the limiting plate 12; the left and right end surface of the two supporting plates 111 abuts against the front and rear inner side of the rectangular cylinder 1 respectively, and is converted to abut against the opposite side of the corresponding two limiting strips 13; since the distance between the bottom surface of the limiting plate 12 and the annular disc 51 is less than the height of the rotating seat 11, i.e. the height of the supporting plate 111, when the positioning round rod 3 moves down to abut against the top surface of the annular disc 51, the opposite side of the two supporting plates 111 still abuts against the opposite side of the limiting plate 12 respectively, and the left and right end surface of the two supporting plates 111 still abuts against the opposite side of the corresponding two limiting strips 13 respectively; at this time, the positioning round rod 3 presses the supporting plate 111 on the top surface of the annular disc 51, and the limiting plate 12 and the limiting strip 13 guide and position the supporting plate 111.
