This is time-consuming and labor-intensive, and manual marking is prone to errors, making it difficult to ensure the consistency of the stud welding height. When the deviation is too large, it needs to be ground off and re-marked, which affects the stud welding efficiency and welding quality of the rear panel. Utility Model Content

[0004] The present application provides a vehicle rear panel stud welding positioning tool, which solves the problem that manual marking to determine the stud position is prone to deviation, time-consuming and labor-intensive, and easily leads to low welding efficiency and poor welding quality.

[0005] The technical solution adopted in this application is:

[0006] A vehicle rear panel stud welding and positioning tool comprises a support frame, the support frame is a regular rectangular parallelepiped structure, and is horizontally placed parallel to the rear panel of the cab;

[0007] Limiting mechanism: the limiting mechanism comprises a plurality of positioning members detachably connected to the rear panel, and connecting members connecting the positioning members and the support frame, each of the connecting members is fixed to the same outer wall of the support frame, and the positioning member is provided with an avoidance opening for the stud to pass through;

[0008] Clamping mechanism: The clamping mechanism includes a clamp located at the bottom of the rear panel and a quick clamp connected to the clamp, the quick clamp is fixed to the support frame, and the quick clamp drives the clamp to have a first state in which it is engaged with the bottom end of the rear panel and a second state in which it is detached from the rear panel.

[0009] The vehicle rear panel stud welding positioning tool described in this application specifically includes the following additional technical features:

[0010] The positioning member includes a mounting plate, the connecting member includes a connecting bent rod, the mounting plate includes a first mounting portion provided with the avoidance opening and a second mounting portion connected to the connecting bent rod, and the first mounting portion is fixed to the rear panel.

[0011] The first mounting portion includes a mounting plate, the center of the mounting plate extends in all directions to form the avoidance opening, the mounting plate is provided with a first mounting opening, and the positioning member includes a first fastener that passes through the first mounting opening and is fixed to the rear panel.

[0012] The first mounting portion also includes a reinforcing plate connected to the mounting disk, the reinforcing plate is provided with a limiting step, the step surface of the limiting step is engaged with the inner wall of the mounting disk, and the limiting step is provided with a second mounting opening, and the positioning member includes a second fastener connecting the limiting step and the mounting disk through the second mounting opening.

[0013] The second mounting portion is provided with a boss, and the boss is provided with a third mounting opening in a position aligned with the connecting bent rod, and the connecting member includes a third fastener passing through the third mounting opening.

[0014] The connecting bent rod includes a first positioning rod connected to the boss and a second positioning rod connected to the top of the support frame, and the first positioning rod is vertically fixed to the second positioning rod.

[0015] A limiting opening is provided on one side of the support frame close to the rear panel, and the limiting mechanism includes a positioning bolt passing through the limiting opening and fixed to the rear panel.

[0016] A connecting rod and a flip seat are provided between the quick clamp and the clamping jaw, and the connecting rod is hinged to the flip seat.

[0017] The quick clamp rotates around the central axis of the connecting rod to drive the connecting rod to move circumferentially along the flip seat. A rocker is provided between the clamp and the connecting rod. The connecting rod drives the clamp to have a first state and a second state through the rocker.

[0018] The support frame is provided with a weight-reducing opening and a handle.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] (1) By setting a support frame and a limiting mechanism, multiple positioning members are fixed on the rear panel. At the same time, since the support frame is placed horizontally and the connection between the connecting member, the support frame and the positioning member enables the multiple positioning members to be located at the same horizontal height, multiple avoidance openings are located at the same horizontal height. By limiting the avoidance openings during welding, multiple studs can be welded at the same horizontal height, avoiding errors caused by manual marking and skewing. In addition, multiple positioning members can be connected to the support frame through the connecting member first, and the distance between each positioning member can be directly determined, thereby further improving the accuracy of the stud welding position, improving the welding efficiency and welding quality.

[0021] In addition, through the quick clamp and claws of the clamping mechanism, the claws are in the first state when the tooling is used, and the claws are engaged with the bottom end of the rear panel. Since the claws are connected to the quick clamps, and the quick clamps are fixed to the support frame, in the first state, the support frame is further limited by the engagement of the claws to prevent the support frame from shaking and affecting the position accuracy of the connecting parts and the positioning parts; after welding is completed, the quick clamps are rotated and the claws are in the second state, releasing the limitation of the support frame by the claws, making it easy to remove the support frame.

[0022] (2) By setting up a mounting plate and connecting the mounting plate in partitions, the first mounting part fixes the mounting plate to the rear panel, and the second connecting part fixes the mounting plate to the connecting bent rod, thereby achieving support and limiting effects on the mounting plate through the connection between the connecting bent rod and the support frame.

[0023] (3) The mounting plate is fixed to the rear panel and the connecting bent rod. A clearance opening is formed in the center of the mounting plate and fixed on all sides to ensure accurate alignment of the clearance opening with the rear panel. The mounting plate is positioned to avoid displacement of the mounting plate. The mounting plate is fixed to the rear panel by a first fastener and a second fastener. At the same time, the engagement between the reinforcing plate and the mounting plate improves the strength of the mounting plate, thereby further ensuring its position accuracy and avoiding position displacement due to welding vibration.

[0024] (4) By setting a boss and a connecting bent rod fixed by a third fastener, the boss is inconsistent with the first mounting portion in height, which can reduce the impact on the first mounting portion during fixation, and is conducive to dispersing the force, enhancing the overall structural stability of the mounting plate, and facilitating operation.

[0025] (5) By setting a vertical first positioning rod and a second positioning rod, the mounting plate and the support frame can be connected at different angles, thereby improving the force stability, increasing the contact area with the support frame, and strengthening the structural stability of the support frame.

[0026] (6) By setting positioning bolts, the connection strength between the support frame and the rear panel is strengthened, the stable placement of the support frame is ensured, and the support frame is prevented from being skewed due to vibration, thereby realizing the supporting and limiting effect of the support frame on the positioning member, which is beneficial to improving the welding efficiency and welding quality of the rear panel bolts.

[0027] (7) A quick clamp is provided to drive the connecting rod and then the clamp to move, so that the clamp can be engaged and disengaged from the rear panel. During the use of the tooling, the clamp is engaged with the bottom end of the rear panel to limit the support frame, thereby ensuring the stability of the support frame, thereby ensuring the accurate position of the rear panel bolt welding and improving the welding efficiency and welding quality.

[0028] (8) By setting a weight-reducing opening on the support frame, the weight of the support frame is reduced, thereby reducing the force of the support frame on the limit mechanism, avoiding the downward movement of the positioning member due to excessive gravity of the support frame, which is conducive to ensuring the accuracy of the welding position and reducing the operating burden of the staff. Setting a handle on the support frame is also convenient for the staff to take and put, improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0044] The present application provides a stud welding and positioning tool for a rear panel 10 for a vehicle, such as Figures 1 to 4 As shown, it includes a support frame 1, which is a regular rectangular parallelepiped structure and is placed horizontally parallel to the rear panel 10 of the cab;

[0045] Limiting mechanism: The limiting mechanism includes a plurality of positioning members detachably connected to the rear panel 10, and connecting members connecting the positioning members and the support frame 1, each connecting member is fixed to the same outer wall of the support frame 1, and the positioning member is provided with an avoidance opening 213 for the stud to pass through;

[0046] Clamping mechanism: The clamping mechanism includes a clamping claw 7 located at the bottom of the rear panel 10 and a quick clamp 4 connected to the clamping claw 7. The quick clamp 4 is fixed to the support frame 1. The quick clamp 4 drives the clamping claw 7 to have a first state in which it is engaged with the bottom end of the rear panel 10 and a second state in which it is detached from the rear panel 10.

[0047] In this solution, a plurality of positioning members are fixed on the rear panel 10 by setting a support frame 1 and a limiting mechanism. At the same time, since the support frame 1 is placed horizontally and the connection between the connecting member, the support frame 1 and the positioning member enables the plurality of positioning members to be located at the same horizontal height, the plurality of avoidance openings 213 are located at the same horizontal height. By limiting the avoidance openings 213 during welding, the welding of the plurality of studs at the same horizontal height is achieved, and errors caused by manual marking and distortion are avoided. In addition, the plurality of positioning members can be first connected to the support frame 1 through the connecting member, and the distance between each positioning member can be directly determined, thereby further improving the accuracy of the stud welding position, and improving the welding efficiency and welding quality.

[0048] In addition, through the quick clamp 4 and the claw 7 of the clamping mechanism, the claw 7 is in the first state when the tooling is used, and the claw 7 is engaged with the bottom end of the rear panel 10. Since the claw 7 is connected to the quick clamp 4, and the quick clamp 4 is fixed to the support frame 1, in the first state, the support frame 1 is further limited by the engagement of the claw 7 to prevent the support frame 1 from shaking and affecting the position accuracy of the connecting parts and the positioning parts; after the welding is completed, the quick clamp 4 is rotated, and the claw 7 is in the second state, and the limitation of the support frame 1 by the claw 7 is released, so that the support frame 1 can be easily removed.

[0049] It should be noted that the number of positioning members and connecting members is set according to the number of bolts welded on the rear panel 10 .

[0050] like Figure 2 , Figure 3 As shown, in one embodiment, the positioning member includes a mounting plate 2, the connecting member includes a connecting bent rod 3, the mounting plate 2 includes a first mounting portion 21 provided with an avoidance opening 213 and a second mounting portion 22 connected to the connecting bent rod 3, and the first mounting portion 21 is fixed to the rear panel 10.

[0051] By setting up the mounting plate 2 and connecting the mounting plate 2 in partitions, the first mounting part 21 fixedly connects the mounting plate 2 to the rear panel 10, and the second connecting part fixedly connects the mounting plate 2 to the connecting bent rod 3, thereby achieving the supporting and limiting effect of the mounting plate 2 through the connection between the connecting bent rod 3 and the support frame 1.

[0052] Furthermore, the first mounting portion 21 includes a mounting plate 211 , the center of the mounting plate 211 extends in all directions to form an avoidance opening 213 , the mounting plate 211 is provided with a first mounting opening, and the positioning member includes a first fastener 215 that passes through the first mounting opening and is fixed to the rear panel 10 .

[0053] Furthermore, the first mounting portion 21 also includes a reinforcing plate 212 connected to the mounting disk 211, the reinforcing plate 212 is provided with a limiting step 214, the step surface of the limiting step 214 is engaged with the inner wall of the mounting disk 211, and the limiting step 214 is provided with a second mounting port, and the positioning member includes a second fastener 216 that passes through the second mounting port to connect the limiting step 214 and the mounting disk 211.

[0054] The mounting plate 211 is used to fix the rear panel 10 and the connecting bent rod 3. A clearance opening 213 is formed in the center of the mounting plate 211, and the mounting plate 211 is fixed on all sides to ensure that the clearance opening 213 is accurately aligned with the rear panel 10. The mounting plate 211 is positioned to avoid displacement of the mounting plate 211. The mounting plate 211 is fixed to the rear panel 10 by the first fastener 215 and the second fastener 216. At the same time, the engagement of the reinforcing plate 212 and the mounting plate 211 improves the strength of the mounting plate 211, thereby further ensuring its position accuracy and avoiding position displacement due to welding vibration.

[0055] Preferably, the first fastener 215 and the second fastener 216 are respectively arranged on both sides of the mounting plate 211 to achieve symmetrical fixation of the mounting plate 211, and the step surface of the limiting step 214 is engaged with the inner wall of the mounting plate 211, which can further reduce the space of the avoidance opening 213 and the welding range, which is beneficial to the position accuracy of the stud welding.

[0056] It should be noted that the mounting plate 211 is an integral structure, the first mounting portion 21 and the second mounting portion 22 are integrally formed, and no other connection structure is required between the first mounting portion 21 and the second mounting portion 22 .

[0057] In one embodiment, the second mounting portion 22 is provided with a boss 221, and a third mounting opening is provided in alignment with the boss 221 and the connecting bent rod 3, and the connecting member includes a third fastener 33 passing through the third mounting opening.

[0058] By setting the boss 221 and the connecting bent rod 3 to be fixed via the third fastener 33, the boss 221 is not in accordance with the height of the first mounting portion 21, which can reduce the impact on the first mounting portion 21 during fixing, and is conducive to dispersing the force, enhancing the overall structural stability of the mounting plate 2, and facilitating operation.

[0059] Furthermore, the connecting bent rod 3 includes a first positioning rod 31 connected to the boss 221 and a second positioning rod 32 connected to the top of the support frame 1 , and the first positioning rod 31 and the second positioning rod 32 are vertically fixed.

[0060] By setting a vertical first positioning rod 31 and a second positioning rod 32, connections with the mounting plate 2 and the support frame 1 at different angles are achieved, the force stability is improved, and the contact area with the support frame 1 is increased, thereby strengthening the structural stability of the support frame 1.

[0061] It should be noted that the first fastener 215, the second fastener 216 and the third fastener 33 are all fasteners in the prior art, and are not specifically limited. For example, the first fastener 215 is a positioning pin, and the second fastener 216 and the third fastener 33 are screws or bolts. The connection between the second positioning rod 32 and the support frame 1 can be achieved by screws or other common fasteners.

[0062] like Figure 2 As shown, in one embodiment, a limiting opening is provided on one side of the support frame 1 close to the rear panel 10 , and the limiting mechanism includes a positioning bolt 9 passing through the limiting opening and fixed to the rear panel 10 .

[0063] By providing the positioning bolts 9, the connection strength between the support frame 1 and the rear panel 10 is strengthened, the stable placement of the support frame 1 is ensured, and the support frame 1 is prevented from being skewed due to vibration, thereby realizing the supporting and limiting effect of the support frame 1 on the positioning member, which is beneficial to improving the efficiency and welding quality of the bolts of the rear panel 10.

[0064] Preferably, the positioning bolts 9 are respectively arranged at both ends of the support frame 1 , and the quick clamp 4 is located at the center of the support frame 1 to improve the stability of the support frame 1 .

[0065] like Figure 4 As shown, in one embodiment, a connecting rod 5 and a flip seat 6 are provided between the quick clamp 4 and the clamping jaw 7, and the connecting rod 5 and the flip seat 6 are hinged.

[0066] Furthermore, the quick clamp 4 rotates around the central axis of the connecting rod 5 to drive the connecting rod 5 to move circumferentially along the flip seat 6. A rocker 8 is provided between the clamp 7 and the connecting rod 5. The connecting rod 5 drives the clamp 7 to have a first state and a second state through the rocker 8.

[0067] By setting a quick clamp 4 to drive the connecting rod 5 and then drive the clamping claw 7 to move, the clamping claw 7 can be engaged and disengaged from the rear panel 10. During the use of the tooling, the clamping claw is engaged with the bottom end of the rear panel 10 to limit the support frame 1, thereby ensuring the stability of the support frame 1, thereby ensuring the accurate position of the bolt welding of the rear panel 10 and improving the welding efficiency and welding quality.

[0068] It should be noted that the quick clamp 4 can be any quick clamp 4 in the prior art.

[0069] like Figure 1 As shown, in one embodiment, the support frame 1 is provided with a weight-reducing opening 11 and a handle 12 .

[0070] By providing a weight-reducing opening 11 on the support frame 1, the weight of the support frame 1 is reduced, thereby reducing the force of the support frame 1 on the limit mechanism, avoiding the positioning member from moving downward due to excessive gravity of the support frame 1, which is conducive to ensuring the accuracy of the welding position and reducing the operating burden of the staff. The support frame 1 is provided with a handle 12, which is also convenient for the staff to take and put, and improves the convenience of use.

[0071] Preferably, the support frame 1 is hollow inside, and the outer shell of the support frame 1 is equidistantly provided with a plurality of weight-reducing openings 11 of the same size to ensure that the overall shape of the support frame 1 is uniform and the structure is stable. Handles 12 are provided at both ends of the support frame 1 to facilitate taking the support frame 1 from different sides. The handles 12 can be provided on the side facing the outside or on the top of the support frame 1, which is in line with the operating habits of the staff.
