[0002] The dimensional accuracy requirements for the standard section guide frame of the guide frame climbing type tooling platform are relatively high, and the maximum allowable difference is 40 silk. A tooling fixture with high precision and simple operation is required to assist in production. Since the produced standard section guide frame is a triangular prism structure composed of three columns and two end frames, it is necessary to position and fix each column and end frame respectively. After welding, its overall weight is relatively large, and a hoisting device is required to lift it and place it at the finished product placement position. However, most of the existing welding toolings are fixed toolings, and the standard section guide frame is located inside the welding tooling and cannot be directly lifted, and it is time-consuming and laborious to carry by multiple people. Summary of the Invention

Detailed Embodiments

[0025] The following will describe in detail a specific embodiment of the present invention in conjunction with the accompanying drawings. It should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0026] Embodiment 1 As Figures 1 to 2 shown, a rotary standard section guide frame welding tooling provided by an embodiment of the present invention includes a tooling platform 4 and two tooling seats 3; Among them, the tooling platform 4 has three bearing members 5 corresponding to the three columns 1 of the standard section guide frame one by one. Among them, a column positioning unit for fixing the column 1 is provided on any one of the bearing members 5, and a hoisting window 6 is formed between any one of the bearing members 5 and at least one of the adjacent two bearing members 5, that is Figure 1 a hoisting window 6 is formed between the two bearing members 5 located below and the bearing member 5 located above, and the two bearing members 5 located below directly bear the column 1. Therefore, the standard section after welding cannot be taken out between the two, so a hoisting window 6 cannot be formed between the two; A rotating unit 7 is installed on the tooling seat 3. The rotating unit 7 can drive the tooling platform 4 to rotate until one of the hoisting windows 6 faces upward, so as to facilitate using a lifting device to lift the welded standard section guide frame from the hoisting window 6. Compared with the existing fixed tooling fixture, the discharging time after welding is greatly improved, saving time and effort; Specifically, the two tooling seats 3 are respectively located on both sides of the tooling platform 4. Both ends of the tooling platform 4 have connecting shafts, and bearing seats matching the connecting shafts are installed on both tooling seats 3, that is, the tooling platform 4 is rotatably installed on the two tooling seats 3. The rotating unit 7 is installed on one of the tooling seats 3. The rotating unit 7 of this embodiment selects a motor, and a control console 8 connected to the motor is installed on the tooling seat 3 where the motor is installed; Embodiment 2 As Figures 1 to 4 shown, on the basis of Embodiment 1, a rotary standard section guide frame welding tooling provided by an embodiment of the present invention has the following column positioning unit: The column positioning unit includes a limiting member 10 fixedly installed on the bearing member 5 and two groups of quick clamps 9. One group of quick clamps 9 is used to push the column 1 against the limiting member 10, and the other group of quick clamps 9 is used to push the column 1 against the bearing member 5 or the end frame 2. From Figure 1 this, it can be seen that both groups of quick clamps 9 are existing clamps operated manually, and different forms are adopted to achieve different fixing effects; Figure 1The above-mentioned column positioning units are installed on the two bearing members 5 located below. Since the column 1 located above needs to cooperate with the two end frames 2, it is not necessary for the column 1 to be in contact with the bearing member 5. Therefore, the column positioning unit on the bearing member 5 located above in this embodiment adopts the following structure: a limiting member 10, a quick clamp 9, and a fixing mechanism. The limiting member 10 and the quick clamp 9 are the same as above. The fixing mechanism includes an output unit 11, a connecting frame 12, and a fixing rod 13. The output unit 11 is a cylinder or an oil cylinder, and its output end is connected to the connecting frame 12. The fixing rod 13 penetrates through the bearing member 5 and is connected to the connecting frame 12. Under the action of the cylinder or the oil cylinder, the fixing rod 13 moves downward, thereby pushing the column 1 into close fit with the two end frames 2; The number of the above-mentioned quick clamps 9 and the fixing mechanism is not one. Each group of quick clamps 9 of the column positioning unit in this embodiment selects two or three, and those skilled in the art can also make an adaptive selection according to the actual situation; In addition, two end positioning units corresponding to the two end frames 2 of the standard section guide frame are also installed on the tooling platform 4 in this embodiment. One end positioning unit is fixedly installed on the tooling platform 4, and the other end positioning unit is installed on a movable plate 17; Specifically, the end positioning unit includes three limit blocks one 14 corresponding to the three columns 1 one by one and three limit blocks two 15 corresponding to the three hypotenuses of the end frame 2. Since the end of the column 1 has a cylindrical structure, the limit block one 14 can be in the shape of a sleeve; Both the limit block one 14 and the limit block two 15 of the end positioning unit can be designed as detachable structures, so as to be replaced when worn after long-term use and maintain the welding accuracy. The specific detachable structure can adopt bolt fixation or thread fit; in addition, in some other embodiments, the limiting member 10 also adopts a detachable structure, which can be replaced when there are batch size differences in the raw materials or the limiting member 10 is worn. Specifically, it can adopt the form of a fixed block + a replaceable block. The fixed block is connected to the bearing member 5, and the replaceable block is fixed and combined through an embedded bolt; A linear driving mechanism 16 is installed on the tooling platform 4. The linear driving mechanism 16 can be a cylinder or an oil cylinder. The output end of the linear driving mechanism 16 is connected to the movable plate 17. A driving handle connected to the linear driving mechanism is arranged on the tooling platform 4. Through the operation of the driving handle, under the action of the linear driving mechanism 16, the movable plate 17 can move along the length direction of the standard section guide frame, so as to abut against one of the end frames 2, realizing the fixation of the entire standard section guide frame.

[0027] Embodiment III As Figures 1 to 9As shown, on the basis of the second embodiment, a rotary standard section guide frame welding tooling provided by an embodiment of the present invention. To meet the welding work of standard section guides of various sizes, the limiting member 10 of the welding tooling in this embodiment includes a limiting frame 18, a third limiting block 19, and an adjusting block 20; A movable shaft 21 is installed on the limiting frame 18. Both the third limiting block 19 and the adjusting block 20 are installed on the movable shaft 21. A plurality of corresponding adjusting tooth groups 22 are provided on the opposite sides of the third limiting block 19 and the adjusting block 20. Any one of the adjusting tooth groups 22 has at least two height surfaces 23. By rotating the third limiting block 19 or the adjusting block 20, the distance between the third limiting block 19 and the limiting frame 18 can be adjusted; A first spring 24 and a second spring 25 are sleeved on the movable shaft 21. The first spring 24 is located inside the limiting frame 18, and the second spring 25 is located inside the third limiting block 19. A limiting portion is further provided on the part of the movable shaft 21 outside the limiting frame 18. Under the action of the second spring 25, the third limiting block 19 abuts against the adjusting block 20, and the adjusting block 20 abuts against the limiting portion; During adjustment, manually pull the third limiting block 19 to move, so that the adjusting block 20 has a space for free rotation. Then, rotate the adjusting block 20 according to requirements to change the contact surface of the two adjusting tooth groups 22, thereby changing the distance between the third limiting block 19 and the limiting frame 18, realizing adjustable dimensions, and thus being applicable to the welding and fixing work of columns 1 of different sizes; Since the height difference between adjacent height surfaces 23 is constant, this method can ensure that the adjusted dimension is a fixed dimension, which is more accurate than some existing thread adjustment methods.

[0028] Embodiment Four As Figures 1 to 9 shown, on the basis of the third embodiment, a rotary standard section guide frame welding tooling provided by an embodiment of the present invention. Since a lifting device is used to move the welded standard section guide frame to the finished product placement position, the standard section guide frame should not be hindered by the column positioning unit, the end positioning unit, and the limiting member 10 during the rising process; Based on this, a variety of quick clamps 9 of the column positioning unit in this embodiment are installed on the non-bearing surface of the bearing member 5 (the bearing surface refers to the contact surface between the bearing member 5 and the column 1, and the non-bearing surface refers to the surface of the bearing member 5 that does not contact the column 1). After the fixation is released, the quick clamps 9 are folded into the initial state and will not be on the rising path of the standard section guide frame, so no hindrance will be generated; In order to prevent the end positioning unit from affecting the rise of the standard section guide frame, the limit block 14 of the end positioning unit installed on the movable plate 17 is sleeve-shaped, and the limit block 14 of the other end positioning unit is block-shaped. After the movable plate 17 is separated from the end frame 2, the sleeve-shaped limit block no longer limits the cylindrical structure at the end of the column 1, so the end positioning unit will not affect the rise of the standard section guide frame. The limiting member 10 of this embodiment is connected with a giving-way mechanism, under the action of the giving-way mechanism, the limiting member 10 can move below the contact surface between the bearing member 5 and the column 1; Specifically, the yielding mechanism includes an adjusting member 29 and a linear reciprocating mechanism 33. The linear reciprocating mechanism 33 is installed on the lower side of the bearing member 5. A space for accommodating the linear reciprocating mechanism 33 can be provided on the lower side of the bearing frame. The linear reciprocating mechanism 33 of this embodiment can be a cylinder / oil cylinder / linear guide rail. The limiting frame 18 is an L-shaped structure, a part of which is located beside the bearing member 5, and the other part is located under the bearing member 5 and connected to the output end of the linear reciprocating movement mechanism 33; The adjusting member 29 is an L-shaped structure, a part of which is located in the limiting frame 18, and the other part is located at the lower side of the bearing member 5. A guide rod 26 is connected to the lower side of the bearing member 5. The end of the guide rod 26 has a limiting block 27 for preventing the adjusting member 29 from being separated from the guide rod 26. The limiting frame 18 is provided with a spring 28 connected to the adjusting member 29. The limiting frame 18 is provided with a groove for providing a moving space for the adjusting member 29. The adjusting member 29 is provided with a clearance groove 30 which cooperates with the end of the movable shaft 21. When the linear reciprocating mechanism 33 drives the limit frame 18 to descend, the limit frame 18 moves downward, and the adjusting member 29 is still in contact with the lower side of the bearing frame under the action of the spring 3 28. A relative displacement occurs between the limit frame 18 and the limit member 10, and the movable shaft 21 can move into the clearance groove 30, that is, a part of the movable shaft 21 is retracted into the limit frame 18, so that the limit block 3 19 is separated from the column 1, thereby reducing the friction between the limit block 3 19 and the column 1. Finally, the limit frame 18 (limit member 10) moves to below the bearing surface of the bearing member 5 in the initial state under the action of the linear reciprocating mechanism 33. At this time, the limit member 10 will not hinder the rise of the standard section guide frame. In some other embodiments, after completing the welding work of the standard section guide frame composed of the columns 1 of other specifications, the welding work of the standard section guide frame composed of the columns 1 of the initial specifications is returned to. In order to quickly realize the reset of the adjustment block 20, that is, to return the limit block 3 19 to the initial position, the adjustment block 20 is connected with two symmetrical ear plates 31, and the ear plates 31 extend into the limit frame 18. The limit frame 18 is provided with a through groove for making way for the ear plates 31, and the through groove will not affect the rotation of the ear plates 31 within a certain angle range; Two push plates 32 are connected to the adjusting member 29. The push plates 32 are located on the moving path of the ear plates 31. When the limit block is in the initial position, both ear plates 31 are parallel to the horizontal plane. When the limit block is in other positions, the two ear plates 31 rotate a certain angle around their centers, so there is a situation where one ear plate 31 is higher and the other ear plate 31 is lower. When the limiting member 10 does not hinder the rising of the standard section guide frame, the linear reciprocating moving mechanism 33 continues to push the adjusting member 29 to move. At this time, the adjusting member 29 is restricted by the limit block four 27 at the end of the guide rod 26 and cannot continue to move downward. The push plate 32 on the adjusting member 29 can abut against one of the ear plates 31, causing the two ear plates 31 to return to the initial position, and the adjusting block 20 to rotate to the initial position, that is, the adjusting block 20 returns to the initial position. As Figure 1 and Figure 5 shown, the assembling steps of the standard section guide frame of this embodiment are as follows: The first step: Place the two columns 1 on the two lower bearing members 5 located in Figure 1 respectively, and push the column 1 to move until the column 1 abuts against the limiting member 10, and fix it through the column positioning unit. The second step: Place the two end frames 2 on both sides inside the tooling platform 4 and fix them through the end positioning unit. The third step: Place the column 1 with a rack under the upper bearing member 5 located in Figure 1 that is, on the two end frames 2, and push the column 1 to move until the column 1 abuts against the limiting member 10, and realize the downward pressing and fixing of the column through the fixing mechanism. The fourth step: First, perform spot welding to fix the dimensions. The fifth step: Start full welding of the welds at various parts of the standard section guide frame. During the process, the motor control button can be started to rotate the middle tooling platform 4 to reduce the welding difficulty of the welds at individual bottom positions and improve work efficiency. The sixth step: After all the welds are welded, place the reinforcing ribs (not shown in the figure) between adjacent two columns, and complete the welding of the reinforcing ribs. Finally, open the quick clamps at various parts, remove the limiting member 10, rotate the tooling platform to the Figure 2 position shown, and use the overhead crane to lift it out.
