Description

Technical Field

[0001] This invention relates to the field of truss processing tooling technology, specifically a truss processing positioning device and truss processing tooling. Background Technology

[0002] A truss is a structure made up of members connected to each other at both ends by hinges. It is a planar or spatial structure composed of straight members and generally has triangular units. Truss members mainly bear axial tension or compression. It can make full use of the strength of materials. When the span is large, it can save materials, reduce self-weight and increase stiffness compared with solid web beams. Trusses are widely used in building steel structures, bridge engineering, crane booms and stage construction and other fields. There is a large and extensive demand for trusses in the market. In the production of trusses, the main frame (chord) and the sub-frame (web members) are usually completed by machining. The quality and efficiency of machining are directly related to the safety and economy of the truss structure.

[0003] Currently, existing truss processing tooling has the following main shortcomings: Balancing positioning accuracy and efficiency is challenging. Positioning uprights and crossbars during truss assembly is difficult, especially since multiple crossbars need to be arranged sequentially along the length of the uprights, leading to low processing efficiency. Existing machining fixtures often use pin connections, manual alignment, or fixed-angle clamping for positioning. For example, using a pin connection between a full-circle pin hole and a pin hole on the chord member's ear plate to fix the chord member requires inserting the pin into the full-circle pin hole to position the chord member on the machining fixture, and pulling the pin out of the hole to remove the arm section. Both positioning and disassembly are inconvenient. Furthermore, existing machining fixtures typically only clamp two members at fixed angles (right angle or flat angle), failing to flexibly fix and process members at different angles to meet the multi-angle processing requirements of truss members. These traditional positioning methods not only have long clamping and alignment times but also suffer from inconsistent benchmarks and low repeatability, making them unsuitable for efficient automated production.

[0004] During processing, the members are prone to deformation, and there is a lack of effective real-time constraints and feedback. In the processing of structures such as truss arms, the chord members need to be fixed to the processing fixture first, and then the web members are processed. After processing, the arm section is removed. Due to the large heat input during processing, the main frame is prone to thermal deformation and deflection caused by residual stress. However, the existing fixtures are mostly single-end fixed or have insufficient clamping rigidity, making it difficult to form a stable rigid constraint on the main frame throughout the processing. At the same time, if the main frame is skewed after welding after processing, the existing technology lacks convenient online detection methods. It is often necessary to remove the workpiece from the fixture and inspect it separately, which means that defective products cannot be corrected in time before the next set of processing.

[0005] The separation of positioning, processing and inspection processes leads to redundancy in the workflow. Existing truss processing fixtures have relatively simple functions, usually only having positioning or clamping functions. Pre-welding positioning, in-welding holding and post-weld inspection need to be completed at different workstations or with the help of different equipment, resulting in long process flow time, high equipment occupancy rate, and the accumulation of errors caused by multiple clamping of workpieces. In addition, although there are technical solutions in the existing fixtures that use electromagnetic adsorption for fixing, they are usually only used as a single clamping method and fail to deeply integrate electromagnetic adsorption with positioning reference and inspection functions.

[0006] In summary, existing truss processing fixtures still have significant shortcomings in terms of positioning efficiency, processing rigidity constraints, and post-weld quality inspection. There is an urgent need for a truss processing positioning device and fixture that can achieve high-precision positioning, rigid holding throughout the process, and online inspection before and after welding. Summary of the Invention

[0007] The purpose of this invention is to provide a truss processing positioning device and truss processing tooling to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a truss processing fixture, comprising a worktable assembly and a displacement assembly. The worktable assembly includes a table body, an electrically controlled slide groove is provided on the inner side of the top of the table body, a first support seat is mounted on the outer end of the top of the table body, and a motor is mounted on the outer end of the first support seat. A rotating disk is provided at the output end of the motor, and four sets of strong magnetic positioning seats are provided on the outer end of the rotating disk. A second support seat is mounted on the outer end of the top of the table body, and a guide shaft is fixed on the outer end of the second support seat. A guide groove is provided on the outer end of the guide shaft, and a rotating seat is provided between the guide shaft and the rotating disk. A main frame is fixed inside the strong magnetic positioning seat, and a displacement assembly is mounted on the top of the electrically controlled slide groove.

[0009] Furthermore, the motor drives the rotating disk to rotate inside the first support base, and the rotating disk and the strong magnetic positioning base are an integrated structure.

[0010] Furthermore, the strong magnetic positioning seat is electromagnetically attracted and fixed to the main frame, and the inner contour dimensions of the strong magnetic positioning seat match the outer contour dimensions of the main frame.

[0011] Furthermore, the displacement assembly includes an electrically controlled slide, a support platform is mounted on the top outer end of the electrically controlled slide, and guide seats are mounted on both outer ends of the support platform. A removal groove is opened at the end of the guide seat, a support base is mounted on the bottom outer end of the guide seat, and an electrically controlled guide wheel is mounted inside the support base. A sub-frame is mounted between the guide seat and the support base.

[0012] Furthermore, the electrically controlled slide block achieves displacement at the top of the platform through an electrically controlled slide groove, and the electrically controlled slide block and the guide shaft are connected by a sleeve.

[0013] Furthermore, the outer surface of the electrically controlled guide wheel is in contact with the outer surface of the subframe, and the outer surface of the subframe is in contact with the inner surface of the guide seat.

[0014] A truss processing positioning device is applied to a truss processing positioning device, comprising a positioning component. The positioning component includes a sleeve ring, an electrically controlled roller disposed inside the sleeve ring, a support frame disposed at the outer end of the sleeve ring, a connecting seat disposed at the end of the support frame, a steering seat disposed inside the connecting seat, a transverse rotating seat disposed at the top outer end of the steering seat, a strong magnetic fixing ring connected to the side of the transverse rotating seat away from the steering seat, a support rod disposed at the outer end of the support frame, a positioning ring disposed at the end of the support rod, a tension spring disposed between the positioning ring and the strong magnetic fixing ring, a tension rope connected between the positioning ring and the strong magnetic fixing ring, a tension sensor fixed in the middle section of the tension rope, extension seats disposed at both outer ends of the positioning ring, an electrically controlled push rod disposed on the side of the extension seat near the strong magnetic fixing ring, and a clamping seat connected to the output end of the electrically controlled push rod.

[0015] Furthermore, the inner contour dimensions of the sleeve ring match the outer contour dimensions of the guide shaft. The electrically controlled roller is located inside the guide groove.

[0016] Furthermore, the strong magnetic fixing ring is electromagnetically attracted to the main frame, and the position of the strong magnetic fixing ring corresponds one-to-one with the position of the strong magnetic positioning seat.

[0017] Furthermore, the positioning ring and the strong magnetic fixing ring are concentrically arranged, and the strong magnetic fixing ring is elastically connected to the positioning ring through a tension spring.

[0018] This invention provides a truss processing positioning device and truss processing tooling, which have the following beneficial effects: 1. This invention solidifies the standard machining dimensions of the truss into a multi-array structure of strong magnetic positioning seats on a rotating disk, enabling the strong magnetic positioning seats to simultaneously perform workpiece holding and reference positioning functions. Through the precise sliding guidance of the positioning components along the guide axis, the truss main frame can be quickly transported and electromagnetically attracted and fixed to a preset standard work position, eliminating the need for manual marking and alignment, and secondary calibration of the reference. Alignment and clamping can be completed in a single action. It abandons the cumbersome clamping methods of traditional pin insertion and removal, manual alignment, etc., simplifying the clamping process and unifying the reference, effectively solving the problems of low positioning efficiency and poor repeatability of traditional tooling, and adapting to the needs of batch and automated processing of truss members.

[0019] 2. This invention achieves functional reuse of the positioning structure, eliminating the need for additional detection sensors. It utilizes an adaptively deflectable strong magnetic fixing ring, an elastic tension structure, and a tension sensor to construct a non-destructive self-inspection mechanism. After the main frame is clamped, the strong magnetic fixing ring can slide along the entire surface of the main frame. The dual-degree-of-freedom deflection structure sensitively responds to defects such as bending, skewing, and dimensional deviations in the main frame, converting minute deformations into changes in tensile force. The tension sensor collects and provides real-time feedback, accurately determining the workpiece's quality status. This structure integrates workpiece detection functionality into the tooling sliding operation, eliminating the need for offline transport and inspection. It features a simplified structure, high detection sensitivity, and lower cost.

[0020] 3. This invention utilizes a strong magnetic positioning seat and a movable strong magnetic fixing ring to form a double-end rigid constraint on the main frame of the truss. This stably restricts workpiece displacement and deformation throughout the entire machining process of the main and auxiliary frames, effectively resisting thermal deformation and residual stress caused by processing heat input, and ensuring the joint angle and assembly accuracy of the members. Simultaneously, this fixture integrates pre-welding positioning, in-welding rigid holding, and post-welding deformation re-inspection functions, allowing all processes to be completed at the same station without the need for multi-station transfers or repeated clamping, completely avoiding the cumulative errors caused by multiple clamping operations. After welding, the sliding detection structure can be used to immediately re-inspect machining deformation defects, quickly trace problems, and promptly correct the workpiece, significantly improving the quality and processing stability of the finished truss.

Detailed Implementation

[0023] Please see Figures 1 to 10The present invention provides a technical solution: a truss processing positioning device and truss processing fixture, including a worktable assembly 1, a positioning assembly 2, and a displacement assembly 4. The worktable assembly 1 includes a table body 101, an electrically controlled sliding groove 102 is provided on the inner side of the top of the table body 101, a first support seat 103 is mounted on the outer end of the top of the table body 101, and a motor 104 is mounted on the outer end of the first support seat 103. A rotating disk 105 is provided at the output end of the motor 104, and a [missing information - likely a device or fixture] is provided on the outer end of the rotating disk 105. Four sets of strong magnetic positioning seats 106, a second support seat 107 is installed at the top outer end of the platform 101, and a guide shaft 108 is fixed at the outer end of the second support seat 107. A guide groove 109 is opened at the outer end of the guide shaft 108. A rotating seat 110 is arranged between the guide shaft 108 and the rotating disk 105. A main frame 3 is fixed inside the strong magnetic positioning seat 106. A displacement component 4 is installed at the top of the electrically controlled slide 102. The motor 104 drives the rotating disk 105 inside the first support seat 103. The rotating disk 105 and the strong magnetic positioning seat 106 are integrated structures. The strong magnetic positioning seat 106 is electromagnetically attracted and fixed to the main frame 3, and the inner contour dimension of the strong magnetic positioning seat 106 matches the outer contour dimension of the main frame 3. The positioning component 2 includes a sleeve ring 201, an electrically controlled roller 202 is provided inside the sleeve ring 201, and a support frame 203 is provided at the outer end of the sleeve ring 201. A connecting seat 204 is provided at the end of the support frame 203, and the connecting seat 204 is provided inside. The device includes a steering seat 205, a transverse swivel seat 206 at the top outer end of the steering seat 205, a strong magnetic fixing ring 207 connected to the side of the transverse swivel seat 206 away from the steering seat 205, a support rod 208 at the outer end of the support frame 203, a positioning ring 209 at the end of the support rod 208, a tension spring 210 between the positioning ring 209 and the strong magnetic fixing ring 207, a tension rope 211 connected between the positioning ring 209 and the strong magnetic fixing ring 207, a tension sensor 212 fixed in the middle section of the tension rope 211, extension seats 213 at both outer ends of the positioning ring 209, an electrically controlled push rod 214 on the side of the extension seat 213 near the strong magnetic fixing ring 207, and a clamping seat 215 connected to the output end of the electrically controlled push rod 214. The inner contour dimensions of the sleeve ring 201 match the outer contour dimensions of the guide shaft 108. The electrically controlled roller 202 is located inside the guide groove 109. The strong magnetic fixing ring 207 is electromagnetically attracted to the main frame 3, and the position of the strong magnetic fixing ring 207 corresponds one-to-one with the position of the strong magnetic positioning seat 106. The positioning ring 209 and the strong magnetic fixing ring 207 are concentrically arranged, and the strong magnetic fixing ring 207 is elastically connected to the positioning ring 209 through the tension spring 210. The specific operation is as follows: When the equipment is in its initial position, the displacement component 4 moves to the leftmost end of the platform 101 via the displacement of the electrically controlled slide block 401 within the electrically controlled slide groove 102. This allows the displacement component 4 to be close to the first support seat 103. Meanwhile, the positioning component 2 moves to the rightmost end of the platform 101 via the rolling of the electrically controlled roller 202 within the guide groove 109, ensuring that the positioning component 2 is close to the second support seat 107. After the initial position displacement of each component is completed, the operator inserts the main frame 3, which needs to be processed, into the strong magnetic fixing ring 207. The strong magnetic fixing ring 207 operates, attracting and fixing the main frame 3. After all four sets of strong magnetic fixing rings 207 are inserted into the main frame 3, the rolling of the electrically controlled roller 202 within the guide groove 109 drives the main frame 3 to move. The connecting ring 201 and the support frame 203 are displaced along the guide shaft 108. During this process, the electrically controlled push rod 214 at the outer end of the extension seat 213 works, enabling the clamping seat 215 to fix and clamp the strong magnetic fixing ring 207. This ensures that the strong magnetic fixing ring 207 does not shift, thus ensuring the positional accuracy between the strong magnetic fixing ring 207 and the strong magnetic positioning seat 106. Since the positions of the strong magnetic fixing ring 207 and the strong magnetic positioning seat 106 correspond one-to-one, the rolling displacement of the electrically controlled roller 202 allows the front end of the main frame 3 to be inserted into the strong magnetic positioning seat 106. At this time, the strong magnetic positioning seat 106 works and can stably attract and fix the main frame 3. The arrangement of the four sets of strong magnetic positioning seats 106 is the position of the main frame 3 in a standard-sized truss. This design allows for simultaneous positioning and fixing of the main frame 3 and the assembly position. After the main frame 3 is fixed to the magnetic positioning seat 106, the magnetic retaining ring 207 releases its electromagnetic attraction to the main frame 3. At this time, the electrically controlled roller 202 drives the support frame 203 to move towards the second support seat 107. Simultaneously, the electrically controlled push rod 214 drives the clamping seat 215 to retract, which releases the lock of the magnetic retaining ring 207. Since the magnetic retaining ring 207 is sleeved with the main frame 3, after the lock of the magnetic retaining ring 207 is released, the magnetic retaining ring 207 will move along the main frame 3 as a guide. During the movement, if the main frame 3 is bent or skewed, the magnetic retaining ring 207 will move through the connecting seat 204 during the movement. The internal rotating seat 205 and the horizontal rotating seat 206 rotate to achieve position adjustment. After the strong magnetic fixing ring 207 is displaced, the tension spring 210 at its outer end will be stretched or contracted, causing the tension value of the tension rope 211 between the strong magnetic fixing ring 207 and the positioning ring 209 to change. With this design, the operator only needs to judge the value change of the tension sensor 212 in the middle of the tension rope 211 to clearly determine whether there is a defect in the main frame 3. If there is no defect in the main frame 3, the electric control push rod 214 works to drive the clamping seat 215 to fix the strong magnetic fixing ring 207 again, and the electric control roller 202 works to drive the strong magnetic fixing ring 207 to move closer to the strong magnetic positioning seat 106 again, leaving an assembly gap between it and the displacement component 4 (such as...). Figure 1 This allows the main frame 3 to be positioned at both ends by the strong magnetic fixing ring 207 and the strong magnetic positioning seat 106 during the processing and assembly of the main frame 3 and the sub-frame 5, which greatly ensures the processing accuracy of the main frame 3 and the sub-frame 5.

[0024] Please see Figures 1 to 10 The displacement assembly 4 includes an electrically controlled slide 401. A support platform 402 is mounted on the top outer end of the electrically controlled slide 401, and guide seats 403 are mounted on both outer ends of the support platform 402. A displacement groove 404 is opened at the end of the guide seat 403. A support base 405 is mounted on the bottom outer end of the guide seat 403, and an electrically controlled guide wheel 406 is mounted inside the support base 405. A sub-frame 5 is mounted between the guide seat 403 and the support base 405. The electrically controlled slide 401 is displaced at the top of the platform 101 through the electrically controlled sliding groove 102. The electrically controlled slide 401 is sleeved with the guide shaft 108. The outer surface of the electrically controlled guide wheel 406 is in contact with the outer surface of the sub-frame 5, and the outer surface of the sub-frame 5 is in contact with the inner surface of the guide seat 403. The specific operation is as follows: After the main frame 3 completes double-end positioning, the movement of the electrically controlled slide 401 within the electrically controlled slide groove 102 drives the support platform 402 to move to the processing point of the main frame 3 and the sub-frame 5. At this time, the electrically controlled guide wheel 406 inside the support base 405 works, moving the sub-frame 5 inside the guide seat 403 to the foremost point of the guide seat 403. The foremost point of the guide seat 403 is the docking point between the sub-frame 5 and the main frame 3. After the sub-frame 5 moves to the foremost point of the guide seat 403, the external processing robot works to process the sub-frame 5 and the main frame 3. After processing is completed, the electrically controlled slide 401 moves again within the electrically controlled slide groove 102, and the sub-frame 5, which has completed processing with the main frame 3, slides out of the guide seat 403 through the removal groove 404. This operation is repeated. This allows for the machining of the main frame 3 and the sub-frame 5. Furthermore, after machining a single set of main frames 3 and sub-frame 5, the electrically controlled push rod 214 drives the clamping seat 215 to separate the strong magnetic fixing ring 207. The strong magnetic fixing ring 207 can then move again along the main frame 3. Detection during displacement effectively determines whether there is machining misalignment between the main frame 3 and the sub-frame 5, greatly improving the machining quality of the truss. After machining the main frames 3 and sub-frame 5 on both sides, the positioning component 2 and the displacement component 4 move to the rightmost side of the platform 101. At this time, the positioning component 2 and the displacement component 4 move out of the outermost range of the main frame 3. The motor 104 drives the rotating disk 105 to rotate, allowing the unmachined portion of the sub-frame 5 to be laid horizontally (e.g., ...). Figure 7 At this point, the displacement component 4 can be moved back to complete the machining of the main frame 3 and the auxiliary frame 5.

[0025] In summary, when the truss processing positioning device and truss processing fixture are in use, the displacement component 4 moves to the leftmost end of the platform 101 through the displacement of the electrically controlled slide block 401 in the electrically controlled slide groove 102 when the equipment is in the initial position. This allows the displacement component 4 to be close to the first support seat 103. Meanwhile, the positioning component 2 moves to the rightmost end of the platform 101 through the rolling of the electrically controlled roller 202 in the guide groove 109, so that the positioning component 2 is close to the second support seat 107. After the initial position displacement of each component is completed, the worker inserts the main frame 3, which needs to be processed, into the strong magnetic fixing ring 207. The strong magnetic fixing ring 207 operates, attracting and fixing the main frame 3. After all four sets of strong magnetic fixing rings 207 are inserted into the main frame 3, the rolling of the electrically controlled roller 202 in the guide groove 109 drives the sleeve ring 201 and the support frame 203 to move along the guide shaft 108. During this process, the electrically controlled push rod 214 at the outer end of the extension seat 213 operates, enabling the clamping seat 215 to fix and clamp the strong magnetic fixing ring 207, which ensures strong magnetic fixation. The ring 207 does not shift, thus ensuring the positional accuracy between the strong magnetic fixing ring 207 and the strong magnetic positioning seat 106. Since the positions of the strong magnetic fixing ring 207 and the strong magnetic positioning seat 106 correspond one-to-one, the front end of the main frame 3 can be inserted into the strong magnetic positioning seat 106 through the rolling displacement of the electrically controlled roller 202. At this time, the strong magnetic positioning seat 106 works and can be stably attracted and fixed with the main frame 3. The four sets of strong magnetic positioning seats 106 are arranged in the position of the main frame 3 in a standard truss. Through this design, the positioning of the assembly position can be achieved at the same time as the positioning and fixing of the main frame 3. After the main frame 3 is fixed to the magnetic positioning seat 106, the magnetic fixing ring 207 will release its electromagnetic attraction to the main frame 3. At this time, the electrically controlled roller 202 will drive the support frame 203 to move towards the second support seat 107. Simultaneously, the electrically controlled push rod 214 will drive the clamping seat 215 to retract, which will release the locking of the magnetic fixing ring 207. Since the magnetic fixing ring 207 is sleeved with the main frame 3, after the locking of the magnetic fixing ring 207 is released, the magnetic fixing ring 207 will move along the main frame 3 as a guide. During the displacement, if the main frame 3 itself is bent or skewed, the magnetic fixing ring 207 will adjust its position through the rotation of the steering seat 205 and the transverse rotating seat 206 inside the connecting seat 204. After the magnetic fixing ring 207 is displaced, it will adjust the position of its outer end. The tension spring 210 is stretched or contracted, which causes the tension value of the tension rope 211 between the strong magnetic fixing ring 207 and the positioning ring 209 to change. With this design, the operator only needs to judge the value change of the tension sensor 212 in the middle of the tension rope 211 to clearly determine whether there are defects in the main frame 3. If there are no defects in the main frame 3, the electric control push rod 214 works to drive the clamping seat 215 to fix the strong magnetic fixing ring 207 again. The electric control roller 202 works to drive the strong magnetic fixing ring 207 to approach the strong magnetic positioning seat 106 again, and leave an assembly gap between it and the displacement component 4. This allows the main frame 3 to be positioned at both ends through the strong magnetic fixing ring 207 and the strong magnetic positioning seat 106 during the processing and assembly of the main frame 3 and the sub-frame 5. This can greatly ensure the processing accuracy of the main frame 3 and the sub-frame 5. Subsequently, after the main frame 3 completes double-end positioning, the movement of the electrically controlled slide 401 within the electrically controlled slide groove 102 drives the support platform 402 to move to the processing point between the main frame 3 and the sub-frame 5. At this time, the electrically controlled guide wheel 406 inside the support base 405 operates, moving the sub-frame 5 inside the guide seat 403 to the foremost point of the guide seat 403. The foremost point of the guide seat 403 is the docking point between the sub-frame 5 and the main frame 3. After the sub-frame 5 moves to the foremost point of the guide seat 403, the external processing robot operates, enabling the processing of the sub-frame 5 and the main frame 3. After processing is completed, the electric... The sliding seat 401 moves again within the electrically controlled sliding groove 102, and the sub-frame 5, which has been processed with the main frame 3, slides out of the guide seat 403 through the removal groove 404. By repeating this operation, the processing of the main frame 3 and the sub-frame 5 can be realized. In addition, after the processing of a single set of main frame 3 and sub-frame 5 is completed, the electrically controlled push rod 214 drives the clamping seat 215 to separate the strong magnetic fixing ring 207. The strong magnetic fixing ring 207 can move again along the main frame 3. By detecting the displacement, it is possible to effectively determine whether there is a processing deviation between the main frame 3 and the sub-frame 5, which can greatly improve the processing quality of the truss. Finally, after the main frame 3 and the sub-frame 5 on the left and right sides are processed, the positioning component 2 and the displacement component 4 will move to the rightmost side of the platform 101. At this time, the positioning component 2 and the displacement component 4 will move out of the far end of the main frame 3. Through the operation of the motor 104, the rotating disk 105 can be rotated, which allows the part that has not been processed with the sub-frame 5 to be placed horizontally. At this time, the displacement component 4 will move back to complete the processing of the main frame 3 and the sub-frame 5.
