Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, and specifically relates to an automotive spot welding tooling. Background Technology

[0002] Spot welding is a resistance welding method that uses electrodes to apply pressure and current to the workpiece, causing localized melting and forming a weld spot. Spot welding is widely used in the automotive manufacturing industry to complete the assembly welding of automotive parts. When spot welding automotive pipe parts, spot welding fixtures are required, namely spot welding equipment and corresponding clamps, to achieve the positioning, fixing and welding of automotive pipe parts. The design and selection of spot welding fixtures directly affect the quality, efficiency and cost of spot welding.

[0003] Currently, automotive parts are typically fixed on a flat worktable during spot welding. Since the spot welding worktable is not easily adjustable in the direction of the operator, the operator has to move forward manually to perform spot welding operations at different locations on the automotive parts. Furthermore, after the automotive parts are spot welded and reinforced, they need to be manually unclamped and removed from the worktable area. Therefore, there is a need for an automotive spot welding fixture to solve the problems existing in the current technology. Utility Model Content

The flipping control mechanism includes a lead screw slide, an adjusting slider, a first hinge seat, a hinge arm, and a second hinge seat. The lead screw slide is located below the support base and the flipping tray, the adjusting slider is slidably connected inside the lead screw slide, the first hinge seat is fixed at the upper end face of the adjusting slider, the second hinge seat is fixed at the lower end face of the flipping tray, and the hinge arm is hinged between the first hinge seat and the second hinge seat.

[0006] It should be noted in the solution that one end of the hinge arm is rotatably connected to the second hinge seat, and the other end of the hinge arm is rotatably connected to the first hinge seat.

[0007] It is worth noting that a drive motor is fixed to one end face of the lead screw slide, a support frame is fixed between the lead screw slide and the support base, and a support cylinder is provided between the lead screw slide and the flip tray. The output end of the support cylinder is suspended below the flip tray.

[0008] Furthermore, it should be noted that a flipping horizontal shaft is provided on one side of the flipping tray, and a flipping groove is provided on one end face of the support base. The flipping horizontal shaft is rotatably connected to the flipping groove of the support base.

[0012] Beneficial effects:

[0013] By controlling the flipping control mechanism and flipping tray, the flipping tray can be adjusted to be closer to the operator by flipping it on the support base. After welding is completed, the flipping tray can be adjusted to tilt downwards at the support base to facilitate the automatic sliding and discharge of the clamping plate after it is released.

[0014] Through the set flipping control mechanism, during use, the lead screw slide and drive motor can adjust the position of the adjustment slider. The sliding distance of the adjustment slider can control the abutment action of the hinge arm on the flipping tray to adjust its tilt angle and maintain the angle state in conjunction with the support cylinder.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Please see Figure 1-4 This utility model provides an automotive spot welding fixture, including a support base 1, a flip plate 2 on one side of the support base 1, and a flip control mechanism 9 below the flip plate 2. The flip control mechanism 9 includes a lead screw slide 10, an adjusting slider 14, a first hinge seat 11, a hinge arm 12, and a second hinge seat 13. The lead screw slide 10 is located below the support base 1 and the flip plate 2. The adjusting slider 14 is slidably connected inside the lead screw slide 10. The first hinge seat 11 is fixed at the upper end face of the adjusting slider 14, and the second hinge seat 13 is fixed at the lower end face of the flip plate 2. The hinge arm 12 is hinged between the first hinge seat 11 and the second hinge seat 13.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that one end of the hinge arm 12 is rotatably connected to the second hinge seat 13, and the other end of the hinge arm 12 is rotatably connected to the first hinge seat 11.

[0023] Further as Figure 3 As shown, it is worth noting that a drive motor 16 is fixed to one end face of the lead screw slide 10, a support frame 8 is fixed between the lead screw slide 10 and the support base 1, and a support cylinder 17 is provided between the lead screw slide 10 and the flip tray 2. The output end of the support cylinder 17 is suspended below the flip tray 2.

[0024] This solution has the following working process: Before use, the flipping pallet 2 is kept in an upward tilted state. The automotive workpiece to be welded is placed between the two clamping plates 4 and clamped and positioned by the control of the clamping cylinder 5. During use, the operator controls the welding gun to perform spot welding on the automotive workpiece. During the welding process, controlling the flipping pallet 2 to flip on the support base 1 can adjust the position closer to the operator. After welding is completed, controlling the flipping pallet 2 to tilt downward at the support base 1 can facilitate the automatic sliding and discharge of the material after the clamping plates 4 are released.

[0025] According to the above working process, controlling the flipping pallet 2 to flip on the support base 1 can adjust the position closer to the operator. After welding is completed, controlling the flipping pallet 2 to tilt downward at the support base 1 can facilitate the automatic sliding and discharge of the clamping plate 4 after it is released.

[0026] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a flipping horizontal shaft 6 is provided on one side of the flipping tray 2, and a flipping groove 7 is opened on one end face of the support base 1. The flipping horizontal shaft 6 is rotatably connected to the flipping groove 7 of the support base 1. During use, the lead screw slide 10 and the drive motor 16 work together to adjust the position of the adjusting slider 14. The hinge arm 12 is hinged between the first hinge seat 11 and the second hinge seat 13. Since the output end of the support cylinder 17 is located below the flipping tray 2 and plays a role in preventing it from falling, the sliding distance of the adjusting slider 14 can control the abutment action of the hinge arm 12 on the flipping tray 2 to achieve the adjustment of its tilt angle and work with the support cylinder 17 to maintain the angle.

[0027] Further as Figure 4 As shown, it is worth noting that a clamping cylinder 5 is fixed to the upper surface of the flipping tray 2, and a clamping plate 4 is fixed to the output end of the clamping cylinder 5.

[0028] Further as Figure 1 As shown, it is worth noting that the two clamping plates 4 are symmetrically distributed on the surface of the flip tray 2, and one end of the clamping plate 4 is fixed with a side support plate 3 on the upper surface of the flip tray 2.

[0029] In summary: controlling the flipping pallet 2 to flip on the support base 1 allows for adjustment to a position closer to the operator. After welding is completed, controlling the flipping pallet 2 to tilt downwards at the support base 1 facilitates the automatic sliding and discharge of the clamping plate 4 after it is released. During use, the lead screw slide 10 and the drive motor 16 work together to adjust the position of the adjusting slider 14. The sliding distance of the adjusting slider 14 controls the abutment action of the hinge arm 12 on the flipping pallet 2, thereby adjusting its tilt angle and maintaining the angle with the support cylinder 17.
