Description

Technical Field

[0001] This utility model relates to the field of battery tray welding technology, specifically a gantry-type hydraulic welding workstation for battery trays. Background Technology

[0002] As a crucial component for heat dissipation in automotive power batteries, the water-cooled plate is typically welded to a ring frame using friction stir welding to form a battery tray. During the welding process, a pressure component is usually used to firmly hold the water-cooled plate against the ring frame to prevent it from lifting during welding, thus optimizing the welding effect.

[0003] Friction stir welding (FSW) typically incorporates positioning mechanisms on the base to horizontally position the bottom of the annular frame, preventing horizontal deviation during welding. However, during the high-speed rotational friction welding process, the water-cooling plate is inevitably transferred to the top of the annular frame, generating stirring force that causes the top of the frame to wobble. This increases the clearance between the water-cooling plate and the frame, and excessive clearance can prevent welding, leading to weld failure. Therefore, to avoid this problem, a common practice is to install multiple sets of pressure components on the top of the annular frame to increase downward pressure and prevent wobble during welding.

[0004] While the aforementioned method of increasing downward pressure can complete welding, this multi-point pressure approach also has some drawbacks. When the ring frame is short, the distance between its top and bottom positioning points is short, resulting in a smaller torque generated by the stirring force. Combined with the clamping effect of multiple pressure components, this effectively reduces the swaying of the top of the ring frame, thus completing the welding. However, when the ring frame is tall, the distance between its top and bottom positioning points is long, resulting in a larger torque generated by the stirring force. This causes the ring frame to sway significantly outward. Furthermore, the pressure components, which appear to be acting as pressure, actually exert a larger eccentric force on the top of the ring frame during its swaying, further increasing the swaying amplitude and causing deformation, ultimately making welding impossible.

[0005] Therefore, the positioning fixtures used in the welding process between the ring frame and the water-cooled plate still need further improvement. Utility Model Content

[0006] To avoid and overcome the technical problems existing in the prior art, this utility model provides a gantry-type battery tray hydraulic welding workstation. This utility model can effectively reduce the lateral deformation of the annular frame during the welding process, thereby improving the welding stability and enhancing the welding effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0013] As a further improvement of this utility model: the base is also provided with a number of beam clamping mechanisms arranged sequentially along the length of the beam. The beam clamping mechanism includes a clamping base fixed on the base, a clamping telescopic rod fixedly installed on the clamping base, and two clamping arms hinged to the clamping base. The front ends of the two clamping arms cooperate to form jaws that clamp the two sides of the beam. The tail ends of the two clamping arms are hinged to the telescopic ends of the clamping telescopic rod through a drive rod. The clamping telescopic rod can perform telescopic movements to open and close the jaws through the drive rod.

[0014] As a further improvement of this utility model: the base is also provided with a number of lifting mechanisms arranged sequentially along the circumference of the water-cooled plate. The lifting mechanism includes a lifting base fixedly installed on the base, and a lifting telescopic rod arranged vertically in the telescopic direction is fixedly installed on the lifting base. A lifting limit block is fixedly installed on the telescopic end of the lifting telescopic rod. The top of the lifting limit block is provided with a limit groove for the protrusion on the lower surface of the water-cooled plate to be inserted, and a positioning pin for being inserted into the positioning hole opened on the water-cooled plate from bottom to top.

[0015] As a further improvement of this utility model: a cooling mechanism is also arranged on the base, the cooling mechanism includes a blower installed on the base, and multiple air knife hinge seats are arranged inside the annular frame.

[0016] As a further improvement of this utility model: the base is also provided with multiple chip removal mechanisms located around the support plate used to support the workpiece to be welded.

[0017] As a further improvement of this utility model: the welding part is an FSW gantry, and the base is installed on the slide table in the welding area of ​​the FSW gantry.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model ensures stable clamping of the annular frame and water-cooled plate through the coordinated action of multiple mechanisms. A flexible clamping mechanism, combined with a contour-following pressure head, achieves precise control of the clamping force, guaranteeing a tight fit at the joint. Simultaneously, the addition of a crossbeam clamping mechanism and a lifting mechanism further enhances the stability and positioning accuracy of the equipment. An integrated cooling mechanism effectively dissipates welding heat, accelerates weld cooling, and improves welding quality. A chip removal function keeps the support plate clean, preventing scratches on the water-cooled plate. Most importantly, it utilizes an FSW gantry as the welding section, combined with sliding table movement, to achieve highly efficient and automated welding of large battery trays. This workstation operates fully automatically from material handling to welding completion, reducing manual intervention and ensuring efficient, stable, and high-quality battery tray production.

[0020] 2. The outer pushing mechanism, through an outer pushing shaft and an outer pushing arm rotatably mounted on the base, effectively clamps the outer side of the ring frame. Its simple structure and uniform clamping force effectively prevent displacement of the ring frame during welding, ensuring welding quality. Simultaneously, the inner pushing mechanism, used in conjunction, clamps the ring frame from both the inner and outer sides, preventing shaking and deformation during welding, thereby further improving welding precision.

[0021] 3. The clamping mechanism adopts a clamping arm and a clamping telescopic rod hinged to the base, which realizes continuous clamping of the water-cooled plate. This not only effectively prevents the water-cooled plate from deforming during the welding process, but also ensures the tightness and firmness of the welded joint.

[0022] 4. The clamping arm is hinged to the connecting rod and driven by the clamping telescopic rod, enabling it to swing up and down in the vertical plane. Simultaneously, the positioning groove on the lower side of the clamping arm cooperates with the positioning block on the mounting base to ensure the clamping arm presses down vertically, guaranteeing the stability and accuracy of the clamping arm during the clamping process. This not only improves the reliability and durability of the clamping mechanism but also effectively prevents the clamping arm from shifting or deforming during the clamping process.

[0023] 5. The beam clamping mechanism, through the coordinated use of the clamping telescopic rod, drive rod, and clamping arm, achieves the clamping and fixing of the beam in the annular frame. This not only effectively prevents deformation and displacement of the beam during welding but also ensures the tightness and strength of the welded joint.

[0024] 6. The combined use of blowers and air knives enables rapid cooling and purging of the welding area. The air knives are arranged sequentially along the circumferential frame, ensuring uniform cooling of the weld seam. This not only improves welding quality and production efficiency but also effectively extends the service life of welding equipment and tooling.

[0025] 7. The flat air knife design ensures uniform airflow distribution and effective purging. Simultaneously, the damping hinge mounted on the air knife hinge frame allows the air knife to be adjusted in angle and position according to actual needs, improving purging effectiveness and adaptability. This not only enhances welding quality and production efficiency but also reduces production costs and maintenance difficulty.

[0026] 8. The welding section adopts an FSW gantry design, which not only boasts high-efficiency welding capabilities and stable welding quality, but also integrates seamlessly with the base and other mechanisms to form a complete welding workstation. This not only improves the automation level and production efficiency of the welding process but also meets the welding requirements of different types and specifications of battery trays. Furthermore, the FSW gantry welding section is easy to operate and maintain, reducing production costs and maintenance complexity. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-10 This utility model mainly includes an outer pushing mechanism 14, an inner pushing mechanism 15, a pressing mechanism 16, a lifting mechanism 17, a crossbeam clamping mechanism 18, a cooling mechanism 12, a chip removal mechanism 13, and a welding part 2.

[0040] The base 1 is mounted on the slide of the FSW gantry, which serves as the welding section 2. When installing the base 1, the base 1 is detachably mounted on the slide of the FSW gantry using a common quick-change mechanism 19 with pin engagement, which facilitates the replacement of the base 1 with a new one for welding battery trays of different sizes.

[0041] like Figures 1-3As shown, the outer push mechanism 14 includes an outer push base 141 fixedly mounted on the base 1. An outer push telescopic rod 142 is fixedly mounted on the outer push base 141, and the telescopic direction of the outer push telescopic rod 142 is arranged vertically. An outer push rotating shaft 143 is also rotatably mounted on the outer push base 141 above the outer push telescopic rod 142, and the rotation axis of the outer push rotating shaft 143 is arranged horizontally. A driven gear is coaxially fixedly connected to the outer push rotating shaft 143, and a driving rack is fixedly mounted on the telescopic end of the outer push telescopic rod 142, with the driving rack and driven gear meshing and transmitting power. An L-shaped outer push arm 144 is also fixedly connected to the outer push rotating shaft 143. An outer push head 146 is fixedly connected to the lower end of the outer push arm 144, and the outer push head 146 is detachably mounted on the outer push arm 144 using a conventional countersunk bolt connection.

[0042] In use, the outer push-telescopic rod 142 is activated, and the driving rack drives the driven gear to rotate. The driven gear, through the outer push-rotating shaft 143, drives the outer push-pressing arm 144 to rotate downwards, causing the outer push-pressing head 146 to press against the joint between the annular frame and the water-cooling plate. This presses the annular frame and water-cooling plate together, ensuring that the upper surfaces of both the annular frame and the water-cooling plate at the joint are on the same horizontal plane. To control the downward angle of the outer push-pressing arm 144, a downward pressure limit block is installed along its path, ensuring that the outer push-pressing arm 144 presses against the joint with the set force. Furthermore, due to wear during use or design errors in the initial design, an outer push-pressing shim 145 is installed between the outer push-pressing arm 144 and the outer push-pressing head 146. This allows for timely adjustment of the thickness of the outer push-pressing head 146, ensuring that the pressure at the joint remains within a preset range.

[0043] In order to reduce the number of outer pushing mechanisms 14 while maintaining the original clamping force, this embodiment also employs the following: Figure 3 The double outer push head 146 structure shown reduces the number of outer push mechanisms 14 by increasing the downward pressing length of the outer push head 146.

[0044] The inner pushing mechanism 15 includes an inner pushing telescopic rod fixedly mounted on the base 1. The telescopic direction of the inner pushing telescopic rod is horizontally arranged, and an inner pushing head is fixedly mounted on the telescopic end of the inner pushing telescopic rod. In use, the inner pushing telescopic rod is driven to extend, thereby causing the inner pushing head to press against the inner side of the corresponding position of the annular frame.

[0045] Each outer pushing mechanism 14 is arranged at equal intervals along the circumference of the annular frame, and a clamping mechanism is installed between adjacent outer pushing mechanisms 14. Simultaneously, on the inner side of the annular frame, each inner pushing mechanism 15 is arranged sequentially along the circumference of the annular frame. The outer pushing head 146 of each outer pushing mechanism 14 mates with the abutment surface of the annular frame to form an outer positioning clamping surface. Similarly, the inner pushing head of each inner pushing mechanism 15 mates with the abutment surface of the annular frame to form an inner positioning clamping surface. The outer and inner positioning clamping surfaces cooperate to form a clamping groove that accommodates the annular frame and simultaneously clamps it from both sides. Of course, in actual use, the outer pushing mechanisms 14 and inner pushing mechanisms 15 can be used interchangeably, or all outer pushing mechanisms 14 or all inner pushing mechanisms 15 can be used to achieve clamping and positioning on both sides of the annular frame.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, the clamping mechanism 16 includes a clamping base 161 fixedly mounted on a base 1. A clamping telescopic rod 162 is fixedly mounted on the clamping base 161, and the telescopic direction of the clamping telescopic rod 162 is arranged vertically. An H-shaped rotating connector 164 is hinged to the clamping base 161, and the top of the rotating connector 164 is hinged to the middle of the clamping arm 163. At the same time, the tail end of the clamping arm 163 is hinged to the telescopic end of the clamping telescopic rod 162, so that the clamping telescopic rod 162 can drive the clamping arm 163 to press down. A guide block 168 is fixedly mounted on the lower side of the front end of the clamping arm 163, and a V-shaped groove is formed on the lower end surface of the guide block 168. The length direction of the V-shaped groove is parallel to the length direction of the clamping arm 163. A positioning block 169 with a top shape adapted to the V-shaped groove for insertion into the V-shaped groove is also arranged on the clamping base 161. A contoured pressure head 167 is detachably installed at the lower end of the pressure arm 163 by means of a countersunk bolt. The shape of the contoured pressure head 167 is adapted to the joint at the pressing point to press it on the joint.

[0047] During use, the telescopic clamping rod 162 extends, at which point the clamping arm 163 begins to swing, driving the rotating connector 164 to rotate, and the contouring pressure head 167 begins to contact the joint. Simultaneously, the rotating connector 164 gradually changes from an inclined state to a vertical state, and in the vertical state, it abuts against the stop block 1610 on the clamping base 161 to prevent the rotating connector 164 from continuing to rotate, thus locking its rotation angle. After locking the rotating connector 164, the telescopic clamping rod 162 also presses the contouring pressure head 167 against the joint, and the clamping arm 163 remains approximately horizontal. During the downward pressing of the clamping arm 163, the V-groove engages with the positioning block 169 from top to bottom, ensuring the clamping arm 163 presses down vertically, guaranteeing the stability and accuracy of the clamping arm 163 during the clamping process, and effectively preventing the clamping arm 163 from shifting or deforming during clamping.

[0048] To improve the accuracy of crimping, a connecting block 1611 is clamped between the lower pressing end of the conforming pressure head 167 and the pressing arm 163. Supporting shims 166 and pressing shims 165 are installed between the connecting block 1611 and the conforming pressure head 167, and between the connecting block 1611 and the pressing arm 163, respectively. The supporting shim 166 between the connecting block 1611 and the conforming pressure head 167 is used to adjust the vertical position of the conforming pressure head 167. The pressing shim 165 between the connecting block 1611 and the pressing arm 163 is used to adjust the horizontal position of the conforming pressure head 167, allowing the conforming pressure head 167 to move along the length of the pressing arm 163 and adjust its position relative to the joint, ensuring that the width of the conforming pressure heads 167 on both sides of the joint is the same.

[0049] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a horizontally arranged crossbeam is present in the annular frame. To prevent deformation of the crossbeam during welding, a crossbeam clamping mechanism 18 is provided. The crossbeam clamping mechanism 18 includes a clamping base 181 fixed on the base 1. A cylinder mounting component 182 is fixedly connected to the clamping base 181. A clamping telescopic rod 184 is mounted on the cylinder mounting component 182 and extends and retracts in the vertical direction. A clamping hinge seat 183 is also fixedly mounted on the clamping base 181. The middle parts of the two clamping arms 186 are simultaneously hinged to the clamping hinge seat 183. A cylinder connector 1810 is fixedly connected to the telescopic end of the clamping telescopic rod 184. Two drive rods 185 are coaxially hinged to the cylinder connector 1810. The two drive rods 185 are respectively hinged to the drive ends of the two clamping arms 186 so that the clamping blocks 189 installed at the front ends of the two clamping arms 186 cooperate to form a jaw for clamping the crossbeam. In order to provide the crossbeam with a proper clamping force, a clamping limit block 187 is installed between the middle of the clamping arm 186 and the jaws by means of a countersunk bolt.

[0050] In use, the clamping telescopic rod 184 extends, driving the two drive rods 185 to move the drive ends of the two clamping arms 186 away from each other. Simultaneously, the two clamping arms 186 rotate around their hinge axes on the clamping hinge seat 183, causing the jaws formed between the two clamping arms 186 to close, thus clamping the two clamping arms 186 onto both sides of the crossbeam. At the same time, two clamping limit blocks 187 abut against the clamping hinge seat 183 between them, thereby controlling the clamping degree of the jaws and preventing excessive clamping force from deforming the crossbeam. Furthermore, to adjust the clamping force according to actual conditions, clamping shims 188 are provided at both the clamping limit blocks 187 and clamping blocks 189. By increasing or decreasing the thickness of the clamping shims 188, the tightening degree of the jaws is limited, thereby controlling the magnitude of the clamping force. Furthermore, multiple beam clamping mechanisms 18 need to be arranged along the same beam according to the actual situation to further improve the stability of clamping, and thus avoid the beam from deforming due to torsional force during welding by multi-point clamping support.

[0051] like Figure 1 , Figure 2 and Figure 7As shown, during the welding process, a lifting mechanism 17 is provided on the base 1 to facilitate the removal of the battery tray formed after welding. The lifting mechanism 17 includes a lifting base 171 fixedly mounted on the base 1, and a vertically arranged lifting telescopic rod 172 fixedly mounted on the lifting base 171. A lifting limit block 173 is fixedly mounted on the telescopic end of the lifting telescopic rod 172. A limit groove 1731 is formed at the top of the lifting limit block 173 for interlocking with a protrusion on the lower surface of the water-cooled plate to horizontally lock the water-cooled plate. A conical positioning pin 1732 is also arranged at the top of the lifting limit block 173 for inserting into a positioning hole formed on the water-cooled plate. Additionally, as... Figure 7 As shown, the top of the lifting limiting block 173 does not have a limiting groove 1731 and a positioning pin 1732; instead, it has a cuboid positioning pin 1732. During use, to horizontally support the water-cooled plate, lifting mechanisms 17 can be arranged at each corner and edge of the water-cooled plate. Preferably, three sets of lifting mechanisms 17 are arranged to achieve three-point positioning without unduly increasing the complexity of the overall device structure.

[0052] like Figure 1 , Figure 2 and Figure 8 As shown, the cooling mechanism 12 includes a blower 121 mounted on the base 1 and located outside the annular frame. Multiple air knife hinge seats 123 are arranged inside the annular frame, and each air knife 122 is mounted on a hinge seat 123 for blowing air. Each air knife 122 is connected to the blower 121. The air knives 122 are arranged sequentially along the direction of the weld, and each air knife 122 blows air towards the weld at its location. Simultaneously, an air outlet is arranged on the base 1 to promptly discharge the heat from the cavity formed by the annular frame and the water-cooled plate, thereby increasing the cooling rate.

[0053] Before welding, adjust the blowing angle of the air knife 122 on the air knife hinge seat 123 according to the position of the weld, and then the weld can be cooled by air during the welding process.

[0054] like Figure 1 , Figure 2 and Figure 9 As shown, after welding is completed and the battery tray is removed, a chip removal structure 13 is provided to prevent aluminum chips from falling onto the support plate 101. The chip removal mechanism 13 includes a vacuum generator base 132 fixedly mounted on the base 1. An angle adjustment block 134 is also damped and hinged to the vacuum generator base 132. A vacuum generator mounting plate 133 is fixedly mounted on the angle adjustment block 134, and a high-flow vacuum generator 131 is fixed on the vacuum generator mounting plate 133.

[0055] In use, by adjusting the angle adjustment block 134 on the vacuum generator base 132, the tilt angle of the vacuum generator mounting plate 133 is adjusted, thereby directing the high-flow-rate vacuum generator 131 to blow air towards the support plate 101. After turning on the high-flow-rate vacuum generator 131, any aluminum shavings that may remain on the support plate 101 can be blown away, preventing aluminum shavings from scratching the water-cooling plate during subsequent welding. Since multiple support plates 101 are installed on the base 1, high-flow-rate vacuum generators 131 are installed near each support plate 101. The high-flow-rate vacuum generators 131 can blow air alternately or simultaneously until all support plates 101 are covered with aluminum shavings.

[0056] The telescopic rod used in this invention can be a telescopic motor, a telescopic hydraulic cylinder, or a telescopic pneumatic cylinder.

[0057] In use, the operator first places the annular frame on the base 1 and simultaneously activates the outer pushing mechanism 14 and the inner pushing mechanism 15 to form a clamping groove, clamping the annular frame within it. Next, the lifting telescopic rod 172 in the lifting mechanism 17 is raised, and the protrusions and positioning holes on the water-cooled plate are then engaged with the limiting groove 1731, positioning pin 1732, and / or positioning post 174. Then, the lifting telescopic rod 172 is shortened, and the water-cooled plate falls into the annular frame. At this time, the protrusions and positioning holes on the water-cooled plate are still engaged with the limiting groove 1731, positioning pin 1732, and / or positioning post 174, but the lifting telescopic rod 172 no longer supports the water-cooled plate. Then, the detection sensor 102 installed on the base 1 emits photoelectric information to detect whether there is a water-cooled plate on the annular frame. If no water-cooled plate is detected, the welding part 2 will not be activated. If a water-cooled plate is detected, all clamping mechanisms 16 are activated and simultaneously clamped at the joint. Then, the welding spindle in the FSW gantry moves to the predetermined initial welding position and begins welding. During welding, each clamping mechanism 16 opens as the welding spindle moves; that is, as the welding spindle moves and welds, the clamping mechanism 16 at the next welding point opens in advance along the joint, avoiding interference with the spindle's movement path. After welding at this point is completed, the corresponding clamping mechanism 16 returns to its original position, ensuring the stability of the water-cooled plate and the annular frame during the welding process.

[0058] After welding is completed, the welding spindle resets, and the lifting telescopic rod 172 lifts the battery tray. Workers remove the battery tray, and the lifting telescopic rod 172 resets, allowing the next round of welding to begin.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
