Description

Technical Field

[0001] This utility model relates to the field of demolding fixture technology, and more specifically, to a friction welding demolding fixture. Background Technology

[0002] Friction welding demolding fixtures are auxiliary equipment designed specifically for friction welding processing scenarios. Their core functions are to achieve precise clamping and positioning of the workpiece to be welded, stable support during the welding process, and safe and efficient demolding after welding, ultimately ensuring the quality and efficiency of friction welding operations.

[0003] However, existing demolding fixtures have the following problems when used:

[0004] Traditional friction welding fixtures often employ a single clamping structure, making it difficult to achieve rigid fixation of the workpiece at multiple points. During the welding process, radial movement of the workpiece can easily lead to misalignment, resulting in defects such as poor coaxiality and insufficient strength of the welded joint, thus increasing the scrap rate of the workpiece. Secondly, the workpiece is easily damaged during the demolding process. Traditional demolding methods often achieve workpiece separation by loosening a single mechanism or by pushing with external force, which can easily cause friction and scratches on the workpiece surface, damaging the appearance of the workpiece. Furthermore, the narrow space for removing the workpiece results in low removal efficiency.

[0005] This invention can accurately clamp the workpiece to be welded, prevent radial movement during welding, monitor the temperature in real time to prevent overheating damage, and safely demold after welding by separating through the clamping mechanism, thus ensuring welding quality and efficiency and improving production stability.

[0016] Beneficial effects:

[0017] 1. By setting up a first clamping mechanism and a second clamping mechanism, a bidirectional stable clamping system can be formed. Both mechanisms work together through mold frame cooperation, slide rail components, and motor drive structures to drive the chucks to precisely adjust the clamping position and force, achieving synchronous multi-point rigid positioning of the two workpieces. This effectively avoids radial movement of the workpieces, providing high-precision positioning assurance for welding and significantly reducing welding defects caused by positioning deviations. The application of the detachable chuck design in the dual mechanisms allows the fixture to flexibly adapt to workpieces of different specifications, significantly expanding its application range. At the same time, both mechanisms are equipped with temperature sensors to simultaneously monitor the temperature of the contact area between the two workpieces and the mechanisms, providing double protection for timely feedback of temperature anomalies. This avoids mold frame deformation, chuck failure, and workpiece overheating, extending the fixture's lifespan and further improving the quality and stability of the welded joint. This comprehensively optimizes the overall welding operation efficiency and effect. In addition, the reverse movement quickly expands the gap, avoiding friction and scratches on the workpiece surface during demolding, ensuring the workpiece's appearance remains intact. Furthermore, the separation action provides ample space for the workpiece to be suspended, facilitating quick removal by manual or automated equipment, further improving demolding efficiency.

[0018] 2. By setting a connecting shaft, the first clamping mechanism and the second clamping mechanism can be firmly connected to form a rigid integral structure, which effectively avoids workpiece positioning deviation caused by the relative displacement of the two mechanisms during the welding process, provides reliable support for the collaborative clamping of the two mechanisms, ensures the coaxiality of the welding joint, and can guide the two clamping mechanisms to move precisely along a fixed trajectory. Whether it is the closed clamping before welding or the reverse separation during demolding, it can ensure smooth and orderly operation, prevent mechanism deviation or jamming, and improve the stability and reliability of the fixture operation. At the same time, the unlocking design of the connecting shaft provides convenience for the demolding process. Simply release its fixed constraint to achieve efficient separation of the two mechanisms, help to quickly complete the demolding of the workpiece, and optimize the overall operation efficiency.

[0019] 3. In summary, this friction welding demolding fixture, through the construction of a first clamping mechanism, a second clamping mechanism, and a connecting shaft, establishes a highly efficient and collaborative operating system. The connecting shaft provides a stable and rigid connection and precise motion guidance for the two clamping mechanisms, ensuring no relative displacement between the two mechanisms. The two clamping mechanisms, with their synchronous multi-point rigid positioning, detachable chucks that flexibly adapt to different workpieces, and real-time monitoring by dual temperature sensors, effectively avoid workpiece displacement and welding defects. The three mechanisms work together to ensure the coaxiality and joint quality of the welded joint. At the same time, the reverse movement quickly expands the gap, avoiding friction and scratches on the workpiece surface during demolding, ensuring the workpiece's appearance remains intact. Furthermore, the separate action provides ample space for the workpiece to be suspended, facilitating quick removal by manual or automated equipment, further improving demolding efficiency, extending fixture life, and comprehensively optimizing the accuracy, stability, and efficiency of friction welding operations.

[0028] The following will refer to the appendix in the embodiments of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0029] Please see Figure 1-7In this embodiment of the present invention, a friction welding demolding fixture includes: a first clamping mechanism 1, a second clamping mechanism 2, and connecting shafts 3. The first clamping mechanism 1 and the second clamping mechanism 2 are arranged opposite to each other and are fixedly connected by connecting shafts 3. The number of connecting shafts 3 is at least four. The first clamping mechanism 1 includes a first mold frame 101, a second mold frame 102, and a third mold frame 103. The connecting shafts 3 pass through the third mold frame 103, the second mold frame 102, and the first mold frame 101 in sequence and are fixedly connected. A temperature sensor 1031 for detecting temperature is provided on one side of the third mold frame 103. The second mold frame 102 is close to the third mold frame 103. A first slide rail assembly 104 is provided on one side. The first slide rail assembly 104 includes two slide rails and at least two slide seats. One end of each of the two slide seats is fixedly connected to a first fixing frame assembly 105. The first fixing frame assembly 105 includes a first fixing frame 1051, a first connecting frame 1052, a first sliding groove 1053, and a first connecting bracket 1054. One end of the first fixing frame 1051 is fixedly connected to the first connecting frame 1052. The first connecting frame 1052 has a first receiving groove. The top of the first connecting frame 1052 has a first sliding groove 1053, which is inclined. The top of the first connecting frame 1052 is movably connected to the first connecting bracket 1054. The third mold frame 103 has a first through hole, and one end of the first connecting frame 1054 is movably connected to the first through hole. A first motor 106 is fixedly installed on one side of the first fixed frame 1051. The output end of the first motor 106 passes through the first fixed frame 1051 and is connected to a first movable rod assembly 107. The first movable rod assembly 107 includes a first movable rod and a first connecting block. The first connecting block is fixedly connected to the bottom end of the first receiving groove opened in the first connecting frame 1052. A first clamping assembly 108 is provided at the bottom end of the first receiving groove opened in the first connecting frame 1052. The first clamping assembly 108 includes a first fixing member 1081 and a first clamp 1082. 1081 is fixedly installed in the first receiving groove. The first clamp 1082 is detachably connected to the first clamp 1081. By setting multiple connecting shafts 3, the connection stability of the first clamping member 1 and the second clamping member 2 can be improved. The two workpieces to be welded are respectively sent into the fixture clamping area: so that the outer wall of the workpiece is initially attached to the inner wall of the first mold frame 101; the other workpiece is placed into the clamping space of the second clamping mechanism 2 to ensure that the welding mating surfaces of the two workpieces are coaxially aligned. The first motor 106 is started, and its output end drives the first movable rod group 107 to rotate: the first connecting block pushes the first connecting frame 1052 to move along the slide rail, and can slide in the front and rear direction of the second mold frame 102.Because the first groove 1053 at the top of the first connecting frame 1052 is inclined, when one end of the first connecting bracket 1054 slides along the groove, the other end extends and retracts along the first through hole of the third mold frame 103, extending towards the workpiece. At the same time, the first clamping component 108 at the bottom of the receiving groove of the first connecting frame 1052 operates: the first fixing member 1081 drives the detachable first chuck 1082 to clamp the workpiece. Combined with the telescopic positioning of the first connecting bracket 1054, multi-point clamping of the workpiece is achieved. If the operation is reversed, the demolding operation of the workpiece is achieved. The second clamping mechanism uses the same operation to stably clamp another workpiece, ultimately keeping the welding mating surfaces of the two workpieces coaxial and with precise spacing, preparing for the friction welding process. The fixture maintains a stable clamping state for the workpiece and sends a signal to the friction welding equipment. After the welding equipment starts, it drives the two workpieces to approach and contact each other along the axial direction. High-speed relative rotation generates frictional heat, raising the mating surfaces to a plastic state and forming a weld joint. During this process, the first chuck 1082 and the first connecting frame 1054 of the first clamping mechanism, together with the second clamping mechanism, provide rigid support to prevent displacement of the workpiece due to rotational torque or axial pressure, ensuring the coaxiality and strength of the weld joint. During welding, the temperature sensor 1031 on the side of the third mold 103 continuously collects temperature data of the contact area between the workpiece and the mold, indirectly reflecting the temperature distribution of the heat-affected zone and transmitting it to the control system in real time. If the temperature is lower than the preset value, it may lead to… If the weld joint fails to fuse, the system sends feedback to the welding equipment, appropriately increasing the rotation speed or axial pressure. If the temperature exceeds the threshold, potentially causing mold deformation, failure of the first chuck 1082, or coarse workpiece grains, the system immediately triggers an alarm, pausing the welding equipment and fixture to prevent equipment damage or workpiece scrap. After the friction welding equipment completes welding, it stops rotating and axially driving, allowing the workpiece to enter a natural or auxiliary cooling stage. The control system uses real-time data from temperature sensor 1031 to determine if the workpiece temperature has dropped to the safe demolding threshold, preventing high-temperature demolding from causing workpiece deformation or burns. Once cooling is confirmed to be adequate, demolding begins, the first motor 106 reverses, and its output drives the first movable rod group 107 in the reverse direction, pulling the first connecting block... The first connecting frame 1052 is reset along the slide rail of the first slide rail assembly 104; the first connecting frame 1054 slides along the inclined first slide groove 1053 of the first connecting frame 1052, and the other end retracts along the first through hole of the third mold frame 103, disengaging from the contact with the outer wall of the workpiece; the first chuck 1082 of the first clamping assembly 108 releases the clamping constraint on the workpiece as the first connecting frame 1052 is reset, completing the unlocking of the first clamping mechanism, and the control system drives the connecting shaft 3 to release the fixation of the first clamping mechanism 1 and the second clamping mechanism 2. Subsequently, the two clamping mechanisms move in opposite directions along the axial direction of the connecting shaft 3: the first clamping mechanism 1 moves away from the second clamping mechanism 2, and the second clamping mechanism 2 moves in the opposite direction, and the distance between them gradually increases;When the two clamping mechanisms are completely disengaged from the surface of the welded workpiece, the separation action stops. At this point, the workpiece is suspended in mid-air, ready for removal, thus achieving demolding. A manual or automated gripping device then extends into the gap between the two clamping mechanisms to remove the welded workpiece and place it in the designated storage area, completing a single demolding operation.

[0030] In this embodiment of the present invention, the second clamping mechanism 2 includes a fourth mold frame 201 and a fifth mold frame 202. A temperature sensor 2021 for detecting temperature is provided on the side of the fifth mold frame 202 away from the fourth mold frame 201. A second slide rail assembly 203 is provided on the side of the fourth mold frame 201 close to the fifth mold frame 202. The second slide rail assembly 203 includes two slide rails and at least two slide blocks. A second fixing frame assembly 204 is fixedly connected to the slide blocks. The second fixing frame assembly 204 includes a second fixing frame 2041, a second connecting frame 2042, a second slide groove 2043, and a second connecting frame 2044. The second fixing frame 2041 is fixedly connected to the slide block, and one end of the second fixing frame 2041 is connected to the first... Two connecting frames 2042 are connected. A second sliding groove 2043 is provided at the top of the second connecting frame 2042. The second sliding groove 2043 is movably connected to the second connecting bracket 2044. The fifth mold frame 202 has a second through hole. One end of the second connecting bracket 2044 is movably connected to the second through hole. One end of the second fixed bracket 2041 is fixedly connected to a second motor 205. The output end of the second motor 205 passes through the second fixed bracket 2041 and is connected to a second movable rod assembly 206. The second movable rod assembly 206 includes a second movable rod and a second connecting block. The second movable rod passes through the second connecting frame 2042 and is connected to the output end of the second motor 205. The second connecting frame 2042 has a second receiving groove. A second connecting block is fixedly connected to one end of the receiving groove, and a second movable rod is connected to one end of the second connecting block. A second clamping assembly 207 is provided at one end of the second receiving groove. The second clamping assembly 207 includes a second fixing member 2071, which is fixedly installed in the second receiving groove. A second clamp 2072 is detachably connected to the second fixing member 2071. When the second motor 205 is started, its output end drives the second movable rod assembly 206 to drive, and the second connecting block pushes the second connecting frame 2042 to slide along the slide rail. Since the second connecting frame 2044 is movably connected to the second slide groove 2043 of the second connecting frame 2042, when the second connecting frame 2042 slides, one end of the second connecting frame 2044... One end slides along the second slide groove 2043, and the other end extends along the second through hole of the fifth mold frame 202 until the end fits against the outer wall of the workpiece B, forming radial positioning; in the second receiving groove of the second connecting frame 2042, the second fixing member 2071 drives the second chuck 2072 to clamp towards the workpiece B, combined with the positioning of the second connecting frame 2044, to achieve multi-point rigid clamping of the workpiece B, ensuring no radial offset, and synchronously clamping with the first clamping mechanism 1, providing a precise positioning basis for friction welding. The two workpieces approach and contact each other along the axial direction, and generate frictional heat through high-speed relative rotation, so that the mating surface is heated to a plastic state; the welding equipment applies axial pressure, pushing the two workpieces to plastically deform and form a welded joint;During this process, the first and second clamping mechanisms provide rigid support through the chucks and connecting frames to counteract rotational torque and axial pressure. The four-column structure improves structural rigidity and stability, ensuring concentricity of the weldments at both ends under welding upsetting pressure, preventing workpiece movement or displacement, and ensuring the coaxiality and strength of the welded joint. During welding, the chucks are prevented from moving back under welding pressure and rotation to prevent the workpiece from loosening, and sufficient demolding force is provided to prevent thermal deformation of the workpiece from holding the chucks in place and preventing demolding. Temperature sensor 1031 and temperature sensor 2021 simultaneously collect data and transmit it to the control system to achieve dual-area monitoring: temperature sensor 2021 collects data on the contact area between the second clamping mechanism and workpiece B. The temperature reflects the temperature distribution of the heat-affected zone of workpiece B, preventing overheating and resulting in coarse grains. After the friction welding equipment stops rotating and axially driving, the workpiece enters a natural or auxiliary cooling stage. The control system uses real-time data from temperature sensor 1031 and temperature sensor 2021 to determine whether the temperature of the weld joint has dropped to the safe demolding threshold. After confirming that the cooling is up to standard, the demolding command is initiated, the second motor 205 reverses, driving the second movable rod assembly 206 to reverse transmission, and the second connecting frame resets and slides: the second connecting block pulls the second connecting frame 2042 to reset along the slide rail of the second slide rail assembly 203 towards the direction closer to the fourth mold frame 201; the second connecting frame 20 44 slides along the second slide groove 2043, and the other end retracts along the second through hole of the fifth mold frame 202, completely detaching from the outer wall of workpiece B; the second chuck 2072 releases the clamping constraint on workpiece B as the second connecting frame 2042 resets, completing the unlocking of the second clamping mechanism; the first motor 106 reverses, driving the first movable rod group 107 to reverse transmission, simultaneously realizing the retraction of the first connecting frame 1054, the release of the clamping constraint on workpiece A by the first chuck 1082, and the release of the fixed constraint on the first and second clamping mechanisms by the connecting shaft 3; the two clamping mechanisms move in opposite directions along the axial direction of the connecting shaft 3: the first clamping mechanism 1 moves away from the second clamping mechanism 2, and the second clamping mechanism 2... Moving in opposite directions, the distance gradually increases until it completely detaches from the welded workpiece; a manual or automated gripping device extends into the gap between the two mechanisms to remove the welded workpiece, completing the demolding operation. Throughout the process, the first and second clamping mechanisms provide rigid support through the chucks and connecting frame, counteracting rotational torque and axial pressure. The four-column structure improves structural rigidity and stability, ensuring concentricity of the welded parts at both ends under welding upsetting pressure, preventing workpiece movement or displacement, and simultaneously ensuring the coaxiality and strength of the welded joint. During welding, the chucks are prevented from moving back under welding pressure and rotation, preventing the workpiece from loosening, and providing sufficient demolding force to avoid the workpiece thermally deforming and holding the chucks in place, preventing demolding.
