Description

Technical Field

[0001] The invention relates to the field of welding tooling, in particular to a rotary standard section guide frame welding tooling. Background Art

[0002] The standard section guide frame of the guide frame climbing tooling platform has high dimensional accuracy requirements, with the maximum allowable difference being 40 threads. A high-precision, simple and easy-to-operate tooling fixture is required to assist in production. Since the standard section guide frame produced is a triangular prism structure consisting of three columns and two end frames, each column and end frame needs to be positioned and fixed separately. After welding is completed, its overall weight is large, and it needs to be lifted by lifting equipment and placed in the finished product display position. However, the existing welding tooling is mostly fixed tooling. The standard section guide frame is located inside the welding tooling and cannot be lifted directly. It is time-consuming and labor-intensive for multiple people to carry it. Summary of the Invention

DETAILED DESCRIPTION

[0033] A specific embodiment of the present invention is described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0034] Example 1

[0035] like Figures 1 to 2 As shown, a rotary standard section guide frame welding tool provided by an embodiment of the present invention includes a tooling platform 4 and two tooling seats 3;

[0036] The tooling platform 4 has three bearing members 5 corresponding to the three columns 1 of the standard section guide frame. Each bearing member 5 is provided with a column positioning unit for fixing the column 1. A hoisting window 6 is formed between each bearing member 5 and at least one of the two adjacent bearing members 5. Figure 1 A lifting window 6 is formed between the two lower bearing members 5 and the upper bearing member 5, and the two lower bearing members 5 directly support the column 1, so the standard section cannot be removed from between the two after welding, so no lifting window 6 can be formed between the two;

[0037] 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 lifting windows 6 faces upward, so that it is convenient to use a lifting device to lift the welded standard section guide frame from the lifting window 6. Compared with the existing fixed tooling fixture, the material discharge time after welding is greatly improved, saving time and labor;

[0038] 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. The two tooling seats 3 are both equipped with bearing seats that cooperate with the connecting shafts. That is, the tooling platform 4 is rotatably mounted on the two tooling seats 3. The rotating unit 7 is installed on one of the tooling seats 3. In this embodiment, the rotating unit 7 is a motor. The tooling seat 3 equipped with the motor is equipped with a control console 8 connected to the motor.

[0039] Example 2

[0040] like Figures 1 to 4 As shown, based on the first embodiment, the embodiment of the present invention provides a rotary standard section guide frame welding tool, and its column positioning unit is as follows:

[0041] The column positioning unit includes a limiter 10 fixedly mounted on the carrier 5 and two sets of quick clamps 9, one set of quick clamps 9 is used to push the column 1 against the limiter 10, and the other set of quick clamps 9 is used to push the column 1 against the carrier 5 or the end frame 2. Figure 1 It can be seen that the two sets of quick clamps 9 are both manually operated existing clamps, and different forms are used to achieve different fixing effects;

[0042] Figure 1 The above-mentioned column positioning units are installed on the two supporting members 5 located at the bottom. Since the column 1 located at the top needs to cooperate with the two end frames 2, the column 1 does not necessarily have to contact the supporting member 5. Therefore, the column positioning unit located on the upper supporting member 5 of this embodiment adopts the following structure: a limit member 10, a quick clamp 9 and a fixing mechanism. The limit 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 an air cylinder or an oil cylinder, and its output end is connected to the connecting frame 12. The fixing rod 13 passes through the supporting member 5 and is connected to the connecting frame 12. Under the action of the air cylinder or the oil cylinder, the fixing rod 13 moves downward, thereby pushing the column 1 to fit tightly with the two end frames 2;

[0043] The number of the quick clamps 9 and the fixing mechanism is not one. In this embodiment, each set of quick clamps 9 of the column positioning unit is selected to be two or three. Those skilled in the art can also make adaptive selections according to actual conditions.

[0044] In addition, the tooling platform 4 of this embodiment is further equipped with two end positioning units corresponding to the two end frames 2 of the standard section guide frame, one of which is fixedly mounted on the tooling platform 4, and the other is mounted on a movable plate 17;

[0045] Specifically, the end positioning unit includes three limit blocks 14 corresponding to the three columns 1 and three limit blocks 15 corresponding to the three oblique sides of the end frame 2. Since the end of the column 1 has a cylindrical structure, the limit block 14 can be a sleeve-shaped structure.

[0046] The first and second limit blocks 14 and 15 of the end positioning unit can be designed as detachable structures so that they can be replaced when they are worn out after long-term use to maintain welding accuracy. The specific detachable structure can be fixed with bolts or threaded. In addition, in some other embodiments, the limit member 10 also adopts a detachable structure. When there are batch size differences in the raw materials or the limit member 10 is worn and needs to be replaced, it can be replaced. 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 assembled by embedded bolts.

[0047] A linear drive mechanism 16 is installed on the tooling platform 4. The linear drive mechanism 16 can be a pneumatic cylinder or an oil cylinder. The output end of the linear drive mechanism 16 is connected to the movable plate 17. A drive handle connected to the linear drive mechanism is provided on the tooling platform 4. The drive handle is used for operation. Under the action of the linear drive mechanism 16, the movable plate 17 can move along the length direction of the standard section guide frame, thereby abutting against one of the end frames 2 to fix the entire standard section guide frame.

[0048] Example 3

[0049] like Figures 1 to 9 As shown, based on the second embodiment, the embodiment of the present invention provides a rotary standard section guide frame welding fixture. In order to meet the welding work of standard section guide frames of various sizes, the limiting member 10 of the welding fixture of this embodiment includes a limiting frame 18, a limiting block 19 and an adjusting block 20;

[0050] A movable shaft 21 is mounted on the limit frame 18, and the limit block 3 19 and the adjustment block 20 are both mounted on the movable shaft 21. A plurality of corresponding adjustment tooth groups 22 are provided on opposite sides of the limit block 3 19 and the adjustment block 20. Each adjustment tooth group 22 has at least two height surfaces 23. By rotating the limit block 3 19 or the adjustment block 20, the distance between the limit block 3 19 and the limit frame 18 can be adjusted.

[0051] The movable shaft 21 is sleeved with a spring 1 24 and a spring 2 25. The spring 1 24 is located in the limit frame 18, and the spring 25 is located in the limit block 3 19. A limit portion is also provided on the portion of the movable shaft 21 located outside the limit frame 18. Under the action of the spring 25, the limit block 3 19 abuts against the adjustment block 20, and the adjustment block 20 abuts against the limit portion.

[0052] During adjustment, manually pull the limit block 3 19 to move so that the adjustment block 20 has space to rotate freely. Then, rotate the adjustment block 20 as needed to change the contact surface of the two adjustment tooth groups 22, thereby changing the distance between the limit block 3 19 and the limit frame 18, thereby achieving size adjustment, thereby being suitable for welding and fixing work of columns 1 of different sizes;

[0053] Since the height difference between adjacent height surfaces 23 is constant, this method can ensure that the adjusted size is a fixed size, which is more accurate than some existing thread adjustment methods.

[0054] Example 4

[0055] like Figures 1 to 9As shown, based on the third embodiment, the embodiment of the present invention provides a rotary standard section guide frame welding tool. 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 will not be hindered by the column positioning unit, the end positioning unit and the limit member 10 during the rising process.

[0056] Based on this, the various quick clamps 9 of the column positioning unit of this embodiment are installed on the non-load-bearing surface of the carrier 5 (the load-bearing surface refers to the contact surface between the carrier 5 and the column 1, and the non-load-bearing surface refers to the surface of the carrier 5 not in contact with the column 1). After the fixation is released, the quick clamps 9 are folded to the initial state and will not be in the ascending path of the standard section guide frame, so there will be no obstruction.

[0057] 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.

[0058] The limiting member 10 of this embodiment is connected to a yielding mechanism, under the action of which the limiting member 10 can move below the contact surface between the bearing member 5 and the column 1;

[0059] Specifically, the yielding mechanism includes an adjusting member 29 and a linear reciprocating mechanism 33. The linear reciprocating mechanism 33 is mounted on the lower side of the carrier 5. A space for accommodating the linear reciprocating mechanism 33 can be provided on the lower side of the carrier. The linear reciprocating mechanism 33 in this embodiment can be a pneumatic cylinder / oil cylinder / linear guide rail.

[0060] The limiting frame 18 is an L-shaped structure, one part of which is located beside the carrier 5, and the other part is located under the carrier 5 and connected to the output end of the linear reciprocating movement mechanism 33;

[0061] The adjusting member 29 is an L-shaped structure, with one portion located within the limiting frame 18 and the other portion located on the lower side of the carrier 5. A guide rod 26 is connected to the lower side of the carrier 5. The end of the guide rod 26 has a limiting block 27 for preventing the adjusting member 29 from detaching 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 space for the adjusting member 29 to move.

[0062] The adjusting member 29 is provided with a clearance groove 30 that 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 support frame under the action of the spring three 28. A relative displacement occurs between the limit frame 18 and the limit member 10, and the movable shaft 21 is able to 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 three 19 is separated from the column 1, thereby reducing the friction between the limit block three 19 and the column 1. Finally, the limit frame 18 (limit member 10) moves to below the bearing surface of the support 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;

[0063] In some other embodiments, after completing the welding work on the standard section guide frame composed of columns 1 of other specifications, the welding work on the standard section guide frame composed of columns 1 of the initial specifications is returned to. In order to quickly reset the adjustment block 20, that is, to return the limit block 3 19 to the initial position, two symmetrical ear plates 31 are connected to the adjustment block 20. The ear plates 31 extend into the limit frame 18. The limit frame 18 is provided with a through slot for making way for the ear plates 31. The through slot does not affect the rotation of the ear plates 31 within a certain angle range.

[0064] The adjusting member 29 is connected to two push plates 32, which are located on the moving path of the ear plates 31. When the limit block is in the initial position, the two ear plates 31 are parallel to the horizontal plane. When the limit block is in other positions, the two ear plates 31 rotate about their centers at a certain angle, so that one ear plate 31 is higher and the other is lower.

[0065] When the limit member 10 does not hinder the rise of the standard section guide frame, the linear reciprocating mechanism 33 continues to push the adjusting member 29 to move. At this time, the adjusting member 29 is restricted by the limit block 27 at the end of the guide rod 26 and cannot move further 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 their initial positions, allowing the adjusting block 20 to rotate to its initial position, that is, allowing the adjusting block 20 to return to its initial position.

[0066] like Figure 1 and Figure 5 As shown, the assembly steps of the standard section guide frame of this embodiment are as follows:

[0067] Step 1: Place the two columns 1 separately Figure 1 The middle part is located on the two bearing members 5 at the bottom, and pushes the column 1 to move until the column 1 contacts the limit member 10 and is fixed by the column positioning unit;

[0068] Step 2: Place the two end frames 2 on both sides of the tooling platform 4 and fix them using the end positioning units;

[0069] Step 3: Place the column 1 with the rack Figure 1 The middle part is located below the upper bearing member 5, that is, on the two end frames 2, and pushes the column 1 to move until the column 1 contacts the limit member 10, and the column is pressed down and fixed by the fixing mechanism;

[0070] Step 4: Spot welding to fix the size first;

[0071] Step 5: Start to fully weld all the welds of the standard section guide frame. During the process, you can start the motor control button to rotate the middle tooling platform 4 to reduce the welding difficulty of individual bottom position welds and improve work efficiency.

[0072] Step 6: After all welds are completed, place reinforcement ribs (not shown in the figure) between two adjacent columns and complete the welding of the reinforcement ribs. Finally, open the quick clamps at each location, remove the limiter 10, and rotate the tooling platform to Figure 2 It can be lifted out by crane from the position shown.

[0073] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0074] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
