Description

Technical Field

[0001] This utility model relates to the field of welding and milling, specifically a positioning support fixture for conductive strip welding and milling. Background Technology

[0002] In the production process of conductive busbar welding, in order to ensure a tight weld between the end of the conductive busbar and the metal terminal, lead-in blocks and lead-out blocks are usually added to assist the welding process. For example... Figure 3 As shown in the figure: 11 is the middle section of conductive busbar 1, 12 is the horizontal terminal of conductive busbar 1, 13 is the bent terminal of conductive busbar 1, 14 and 15 are both lead-in blocks, more specifically, 14 is the lead-in block and 15 is the lead-out block, a is the welding start point and b is the welding end point, and the direction of the line connecting a and b is the welding direction.

[0003] When welding the end of the busbar to the metal terminal, the busbar end and the metal terminal are usually placed on a horizontal welding platform so that the part of the busbar end to be welded to the metal terminal is in contact. At the same time, an inlet block and an outlet block are set on both sides of the contact part, so that the gap of the contact part is arranged along the line connecting the inlet block and the outlet block. Then, a clamp is used to limit and fix the position of the busbar end and the metal terminal, and then the welding head can be used to weld the gap of the contact part.

[0004] After welding is completed, the lead blocks on both sides of the conductive busbar need to be milled off. When milling off the lead blocks, the conductive busbar must be removed from the original welding platform and fixed on a new clamping fixture. This keeps the lead blocks on both sides of the conductive busbar in a suspended state before milling off the lead blocks with a milling cutter. This avoids damage to the original welding platform caused by the milling cutter during the milling process. The welding and milling process requires changing two sets of fixtures to position the conductive busbar separately, which results in low efficiency. Therefore, this problem urgently needs to be solved. Utility Model Content

[0005] To avoid and overcome the technical problems existing in the prior art, this utility model provides a positioning support fixture for welding and milling conductive busbars. This utility model uses a single support fixture to simultaneously achieve different positioning functions for the conductive busbar during the welding and milling processes, thereby improving the welding and milling efficiency of the conductive busbar.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A positioning support fixture for welding and milling conductive busbars includes a support frame for supporting multi-segment conductive busbars. The support frame includes a main support platform for supporting the middle section of the conductive busbar and two sets of side support platforms for supporting the terminals of the conductive busbar. There is a gap between the side support platforms and the main support platform to install a lifting support mechanism. The support blocks are driven to rise and fall by a power source and support the welding surface of the conductive busbar from bottom to top. The middle section of the conductive busbar and the terminals at both ends are pressed and positioned by independent clamping mechanisms.

[0008] As a further embodiment of this utility model: the support mechanism includes a mounting base, in which a mounting cavity is formed along the horizontal direction; a linear power source is disposed in the mounting cavity and can perform telescopic sliding action along the length direction of the mounting cavity; a horizontal wedge is also slidably disposed in the mounting cavity; a lifting channel communicating with the mounting cavity is also formed along the vertical direction in the mounting base; a vertical wedge is disposed in the lifting channel, and the vertical wedge and the horizontal wedge form a wedge surface sliding fit; while the horizontal wedge slides along the mounting cavity, it drives the vertical wedge to perform a lifting action along the lifting channel, thereby supporting the conductive busbar from bottom to top.

[0009] As a further improvement of this utility model: the end of the mounting base away from the linear power source is provided with an opening, which is closed by a pressure cover, and the pressure cover and the mounting base enclose each other to form a lifting channel.

[0010] As a further improvement of this utility model: the linear power source is a linear cylinder, and a floating joint is provided at the end of the linear cylinder. The linear cylinder pushes the horizontal wedge to slide through the floating joint.

[0011] As a further improvement of this utility model: a support block is installed at the end of the vertical wedge block located outside the mounting base via a gasket.

[0012] As a further embodiment of this utility model: the clamping mechanism includes a lifting power source, a first connecting rod is hinged to the telescopic end of the lifting power source, a second connecting rod is hinged to the body of the first connecting rod, the end of the second connecting rod away from the first connecting rod is hinged to the mounting base of the lifting power source, and the hinge axes are parallel in sequence. A pressure block is provided at the end of the first connecting rod away from the telescopic end of the lifting power source. When the telescopic end of the lifting power source extends and retracts, it drives the pressure block on the first connecting rod to rotate, so as to clamp the conductive busbar.

[0013] As a further improvement of this utility model: the clamping mechanism is provided in three sets, and the clamping blocks of each clamping mechanism correspond to the shapes of the middle section and the terminals at both ends of the conductive busbar.

[0014] As a further improvement of this utility model: the table surface of each side support platform is provided with a contour groove, and the contour groove of each side support platform corresponds to the shape of the terminals at both ends of the middle section, so as to allow the terminals to be snapped and positioned.

[0015] As a further improvement of this utility model: the support frame and the clamping mechanism are both fixed on the positioning platform. The positioning platform is detachably fixed on the welding frame by the locking mechanism. The welding tool is suspended above the support frame. The positioning platform is equipped with an adjustment valve to control the start and stop of each clamping mechanism.

[0016] As a further embodiment of this utility model: a sliding block is slidably arranged on the track of the welding frame, and the sliding block is fixed after sliding along the track of the welding frame; a fixing block is arranged on the positioning platform, and the fixing block is connected to the sliding block by an adjusting screw and then locked in place by a nut.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model sets the support frame in a multi-segment arrangement to support the middle section of the conductive busbar and the terminals at both ends. A lifting support mechanism is set between the main support platform and the side support platform of the support frame. The welding area is supported by the lifting and lowering of the support block of the support mechanism. During the welding process, the support block is raised to support the weld area. After the welding is completed, the support block is lowered to facilitate subsequent milling. A set of support fixtures can realize different positioning functions of the conductive busbar in the welding and milling process at the same time, thereby improving the welding and milling efficiency of the conductive busbar.

[0019] 2. The power source of the support structure of this utility model is a horizontal side-pushing mechanism set in the mounting base. Through the sliding cooperation of the wedge surface, the horizontal extension and retraction of the linear cylinder pushes the support block on the vertical wedge to generate a lifting motion, which supports the weld. This avoids the aluminum chips from welding and milling falling into the cylinder and other lifting devices when the vertical cylinder is directly arranged, thus preventing jamming. At the same time, the detachable arrangement of the mounting base cover facilitates installation, disassembly, and cleaning of aluminum chips that fall into the mounting base during the welding and milling process.

[0020] 3. The multi-link arrangement of the clamping mechanism of this utility model, through the extension and retraction of the lifting cylinder, drives the pressure block at the end of the telescopic rod to form a 90-degree flipping action, which clamps the conductive busbar through the flipping action. It has a high space utilization rate. Each clamping mechanism is independently opened and closed by adjusting valve, and clamps different areas of the conductive busbar in multiple stages. Furthermore, by the pressure block of each clamping mechanism corresponding to the shape of the middle section and the terminals at both ends of the conductive busbar, adaptive clamping is performed to improve the clamping effect.

[0021] 4. The support platform of this utility model is provided with a contour groove to form contour support for terminals of different shapes. During welding and milling, the terminals are snapped and positioned, making the positioning more reliable. The fixed block of the positioning platform and the sliding block of the welding frame are locked and positioned by adjusting the screw and nut, which facilitates quick adjustment and locking.

[0036] 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.

[0037] Please see Figures 1-5In this embodiment of the invention, a positioning support fixture for conductive strip welding and milling includes a welding frame 5 and a positioning platform 4 detachably fixed to the welding frame 5 via a locking mechanism 6. Preferably, one or two sets of locking mechanisms 6 are provided. Each locking mechanism 6 includes a sliding block 61 fixed to the welding frame 5 and a fixed block 62 disposed on the positioning platform 4. A guide rail is provided along the length of the welding frame 5, and the sliding block 61 is positioned after sliding along the guide rail. The sliding block 61 and the fixed block 62 are at the same height and are connected by an adjusting screw 63 and locked by a nut, thereby enabling rapid adjustment and locking. The adjusting screw 63 is arranged perpendicularly to the guide rail of the welding frame 5. The mating surfaces of the sliding block 61 and the fixed block 62 are connected by a V-shaped wedge for rapid guiding and positioning.

[0038] The positioning platform 4 is equipped with a support frame 2, which consists of three sets: a main support platform 21 located in the center and side support platforms 22 located on both sides of the main support platform 21. The main support platform 21 is a T-shaped platform, and its top horizontal section is used to support the middle section 11 of the conductive busbar 1. The two side support platforms 22 are respectively set at the two terminals of the conductive busbar 1.

[0039] Both sides of the support platform 22 have contour grooves 23 on their surfaces. The shapes of the two contour grooves 23 correspond to the shapes of the planar terminal 12 and the bent terminal 13 of the conductive busbar 1, respectively, for the terminal to be snapped and positioned.

[0040] After the conductive busbar 1 is installed in place, it is pressed by the clamping mechanism 3 on the positioning platform 4. The clamping mechanism 3 has three sets, corresponding to the middle section 11, the flat terminal 12, and the bent terminal 13 of the conductive busbar 1, respectively. The clamping mechanism 3 includes a lifting power source, preferably a lifting cylinder 31. The telescopic rod 32 of the lifting cylinder 31 is arranged vertically. The telescopic rod 32, the first connecting rod 33, and the second connecting rod 34 are sequentially hinged. The second connecting rod 34 is hinged to the body of the first connecting rod 33 and to the cylinder seat of the lifting cylinder 31, thus forming a closed loop. All hinge axes are arranged parallel to each other.

[0041] As the telescopic rod 32 extends and retracts, it drives the first connecting rod 33 to rotate 90 degrees. The pressure block 35 is fixed to the end of the first connecting rod 33. As the first connecting rod 33 rotates, it drives the pressure block 35 to flip 90 degrees. In the non-working state, the first connecting rod 33 is in a vertical state. In the clamping state, the first connecting rod 33 and the pressure block 35 are in a horizontal state. The pressure blocks 35 of the three sets of clamping mechanisms 3 correspond to the shapes of the middle section 11, the flat terminal 12, and the bent terminal 13, resulting in a more precise clamping action.

[0042] The positioning platform 4 is equipped with multiple sets of regulating valves 7, each regulating valve 7 controlling the opening and closing of the corresponding clamping mechanism 3, independently clamping the intermediate section 11, the flat terminal 12, and the bent terminal 13. After the conductive busbar 1 is clamped and fixed, it is subjected to friction stir welding by the welding tool 9 suspended above the positioning platform 4.

[0043] A support mechanism 8 is also provided between the main support platform 21 and the side support platform 22. The support mechanism 8 provides support for the welding ends of the planar terminal 12 and the bent terminal 13, respectively.

[0044] The support mechanism 8 includes a mounting base 81, with a horizontally oriented mounting cavity inside the mounting base 81. A linear power source, preferably a linear cylinder 82, is fixed inside the mounting cavity. A pressure cap 85 is provided at the end of the mounting base 81, forming a vertically oriented lifting channel between the pressure cap 85 and the mounting base 81. The lifting channel communicates with the mounting cavity. A vertical wedge 86 is slidably disposed within the lifting channel, and a support block 88 is fixed to the end of the vertical wedge 86 outside the mounting base 81 by a gasket 87.

[0045] The sliding trajectory of the horizontal wedge 84 intersects with that of the vertical wedge 86. As the linear cylinder 82 slides along the mounting cavity via the floating joint 83, the horizontal wedge 84 abuts against the vertical wedge 86, forming a wedge-surface sliding fit, which drives the vertical wedge 86 to rise and fall. As the vertical wedge 86 rises, it supports the welding part of the conductive busbar 1 from bottom to top via the support block 88.

[0046] After welding is completed, the horizontal wedge 84 retracts and the vertical wedge 86 retracts synchronously under the action of gravity, thereby disengaging from the conductive busbar 1, which facilitates the subsequent milling of the inlet block 14 and the outlet block 15 at both ends.
