Description
Technical Field
[0001] The present application relates to the technical field of plasma arc guns, and in particular to a plasma arc gun bracket. Background Art

Compared with general arc, plasma arc has stronger penetrating power and can perform heating, perforation welding, and realize operations such as heating or welding of metals. It has high application value in engineering. For plasma arc gun, a suitable bracket is needed for support.
[0003] The orientation of the existing plasma arc gun is determined after it is installed on the bracket. However, when debugging the plasma arc gun, it is necessary to install and adjust the parts at various positions. The orientation of the plasma arc gun cannot be changed quickly, which makes debugging difficult and needs to be improved. Utility Model Content
[0004] In order to facilitate adjustment of the orientation of a plasma arc gun, thereby facilitating debugging of the plasma arc gun, the present application provides a mounting and debugging bracket for a plasma arc gun.

[0007] By adopting the above technical solution, the first bracket and the second bracket can be rotated respectively. When the first bracket and the second bracket are both in a flat state, the direction of the plasma arc gun is horizontal. When the first bracket is in a vertical state and the second bracket is close to and parallel to the first bracket, the direction of the plasma arc gun is vertically downward. When the first bracket is in a flat state and the second bracket is in a vertical state, the direction of the plasma arc gun is vertically upward. Through the installation and debugging bracket of the plasma arc gun, the direction of the plasma arc gun can be quickly adjusted, thereby facilitating the debugging of the plasma arc gun. There is no need to disassemble the plasma arc gun during the adjustment process, which is more convenient to use.

[0009] By adopting the above technical solution, after the first rod and the second rod are unfolded, the first rod and the second rod hold the first bracket to prevent it from excessive rotation; after the first rod and the second rod are folded, the first bracket is restored to a flat state.
[0010] Optionally, a limiting block is fixed to the first rod, and the limiting block is used to abut against a side wall of the second rod to limit the rotation of the second rod.
[0011] By adopting the above technical solution, when the first rod and the second rod are fully unfolded, the limit block is used to abut against the side wall of the second rod to limit the second rod from further rotation, thereby improving stability.
[0012] Optionally, the second limiting assembly includes a third rod hinged to the first bracket and a fourth rod hinged to the second bracket, and the third rod and the fourth rod are hinged to each other.
[0013] By adopting the above technical solution, after the third rod and the fourth rod are unfolded, the third rod and the fourth rod hold the second bracket to prevent it from excessive rotation; after the third rod and the fourth rod are folded, the second bracket is restored to a state parallel to the first bracket.
[0014] Optionally, a limiting block is fixed to the third rod, and the limiting block is used to abut against a side wall of the fourth rod to limit the rotation of the fourth rod.
[0015] By adopting the above technical solution, when the third rod and the fourth rod are fully unfolded, the limiting block is used to abut against the side wall of the fourth rod to limit the fourth rod from further rotation, thereby improving stability.
[0016] Optionally, the fixing assembly includes a fixing frame and a clamping block 1 fixed to the second bracket, and a clamping block 2 rotatably disposed on the fixing frame, and the fixing frame and the clamping block 2 are fixed by setting a locking assembly.
[0017] By adopting the above technical solution, the plasma arc gun is clamped by clamp block 1 and clamp block 2, and the plasma arc gun is locked and fixed by the locking assembly. After the restriction of clamp block 2 is released by the locking assembly, clamp block 2 can be rotated away from clamp block 1, so that the plasma arc gun can be disassembled and assembled and the position can be adjusted.

DETAILED DESCRIPTION
[0037] The following is combined with Figure 1-6 This application is described in further detail.
[0038] Embodiment 1:
[0039] Reference Figure 1 A mounting and debugging bracket for a plasma arc gun comprises a base frame 10, a first bracket 1 rotatably arranged on the base frame 10, and a second bracket 2 rotatably arranged on the first bracket 1. A first limiting component 11 for limiting the rotation angle is provided between the first bracket 1 and the base frame 10, a second limiting component 21 for limiting the rotation angle is provided between the second bracket 2 and the first bracket 1, and a fixing component 3 for fixing the plasma arc gun is provided on the second bracket 2.
[0040] Reference Figure 1 and Figure 2 A support seat 4 for placing a workpiece is slidably provided on the first bracket 1. The material of the support seat 4 is a conductor, such as copper or aluminum. The support seat 4 is fixed with an electrical connection terminal 41. The electrical connection terminal 41 is used to connect to the positive electrode of the power supply and conduct electricity to the workpiece. The workpiece connected to the positive electrode then cooperates with the plasma arc gun of the negative electrode to complete the heating test gun. The position of the workpiece can be adjusted by sliding the support seat 4, thereby adjusting the part of the plasma arc gun facing the workpiece, so as to perform the heating test gun on the required part of the workpiece.
[0041] The support seat 4 is threadedly connected with a fixing bolt 42, the end of which abuts against the first bracket 1, and the fixing bolt 42 is used to limit the sliding of the support seat 4. After tightening the fixing bolt 42, the end of the fixing bolt 42 presses the first bracket 1, and the support seat 4 is limited to slide by static friction, thereby improving the stability during the working process; after loosening the fixing bolt 42, the end of the fixing bolt 42 does not contact the first bracket 1, and then the support seat 4 can be slid by personnel.
[0042] Reference Figure 1 and Figure 3 The fixing assembly 3 includes a fixing frame 30 and a clamping block 1 31 fixed to the second bracket 2, and a clamping block 2 32 rotatably arranged on the fixing frame 30. The fixing frame 30 and the clamping block 2 32 are fixed by setting a locking assembly 33. The materials of the clamping block 1 31 and the clamping block 2 32 are insulating materials, such as nylon and polytetrafluoroethylene, to prevent the electricity of the plasma arc gun from being conducted to the second bracket 2. The clamping block 1 31 and the clamping block 2 32 clamp the plasma arc gun from both radial sides of the plasma arc gun respectively, and the fixing assembly 3 can be arranged in multiple sets at intervals to improve the fixing effect of the plasma arc gun. After the restriction of the clamping block 2 32 is released by the locking assembly 33, the clamping block 2 32 can be rotated away from the clamping block 1 31, so that the plasma arc gun can be disassembled and assembled and the position can be adjusted. The clamping block 1 31 and the clamping block 2 32 can cooperate with the steps of the side wall of the plasma arc gun, so as to avoid the situation where the plasma arc gun slides due to insufficient friction.
[0043] The locking assembly 33 includes a locking block 331 rotatably connected to the fixing frame 30, and a locking bolt 332 is threadedly connected to the locking block 331. The end of the locking bolt 332 abuts against the clamping block 2 32, and the locking bolt 332 is used to press the clamping block 1 31 against the clamping block 2 32. An opening 301 for the locking block 331 to enter is provided on one side of the fixing frame 30. The fixing frame 30 supports the locking block 331 through the groove wall of the opening 301, thereby improving the stability of the locking block 331 when locking the clamping block 2 32. By tightening the locking bolt 332, the locking bolt 332 presses the clamping block 2 32 through the bottom end and continuously presses downward, so that the clamping block 2 32 cooperates with the clamping block 1 31 to reliably clamp the plasma arc gun. After loosening the locking bolt 332, the personnel can cancel the locking of the clamping block 2 32 by rotating the locking block 331 out of the opening 301.
[0044] Reference Figure 1 and Figure 4 The first limiting assembly 11 includes a first rod 111 hinged to the base frame 10 and a second rod 112 hinged to the first bracket 1. The first rod 111 and the second rod 112 are hinged to each other. It should be noted that two sets of the first rod 111 and the second rod 112 are symmetrically arranged, and the two sets of the first rod 111 and the second rod 112 are respectively located on both sides of the first bracket 1 to ensure that the first bracket 1 is subjected to balanced force.
[0045] The first rod 111 is fixed with a limit block 113, which is used to abut against the side wall of the second rod 112 to limit the rotation of the second rod 112. Specifically in this embodiment, when the first rod 111 and the second rod 112 are in the unfolded state, the first bracket 1 is in a vertical state, and the first rod 111 and the second rod 112 pull the first bracket 1 to prevent it from excessive rotation; in this state, the limit block 113 is located on the upper side of the second rod 112, and the limit block 113 is located on the upper side of the hinge axis of the first rod 111 and the second rod 112. The second rod 112 is limited by the limit block 113, thereby preventing the second rod 112 from rotating downward due to gravity, so that the first bracket 1 can be firmly maintained in a vertical state. When it is necessary to reset, the personnel lift the ends of the second rod 112 and the first rod 111 that are close to each other, and the first rod 111 and the second rod 112 can be gradually folded up to restore the first bracket 1 to a flat state.
[0046] Reference Figure 1 and Figure 5 The second limiting assembly 21 includes a third rod 211 hinged to the first bracket 1 and a fourth rod 212 hinged to the second bracket 2. The third rod 211 and the fourth rod 212 are hinged to each other. It should be noted that the third rod 211 and the fourth rod 212 are symmetrically arranged in two sets, and the two sets of the third rod 211 and the fourth rod 212 are respectively located on both sides of the second bracket 2 to ensure that the force of the second bracket 2 is balanced.
[0047] The third rod 211 is fixed with a limiting block 213, which is used to abut against the side wall of the fourth rod 212 to limit the rotation of the fourth rod 212. Specifically in this embodiment, when the first bracket 1 is in a flat state, when the third rod 211 and the fourth rod 212 are in an unfolded state, the second bracket 2 is in a vertical state, and the third rod 211 and the fourth rod 212 pull the second bracket 2 to prevent it from excessive rotation; in this state, the limiting block 213 is located on the upper side of the fourth rod 212, and the limiting block 213 is located on the upper side of the hinge axis of the third rod 211 and the fourth rod 212. The fourth rod 212 is limited by the limiting block 213, thereby preventing the fourth rod 212 from rotating downward due to gravity, so that the second bracket 2 can be firmly maintained in a vertical state. When it is necessary to reset, the personnel lift the ends of the fourth rod 212 and the third rod 211 that are close to each other, and the third rod 211 and the fourth rod 212 can be gradually folded up to restore the second bracket 2 to a flat state.
[0048] The implementation principle of the installation and debugging bracket of a plasma arc gun in the embodiment of the present application is:
[0049] Reference Figure 1When the first rod 111 and the second rod 112 are in a folded state, and the third rod 211 and the fourth rod 212 are also in a folded state, the first bracket 1 and the second bracket 2 are both in a flat state. At this time, the plasma arc gun is oriented horizontally. At this time, a workpiece can be placed on the support seat 4 and the workpiece can be heated by the plasma arc gun.
[0050] Reference Figure 4 When the first rod 111 and the second rod 112 are in the unfolded state, and the third rod 211 and the fourth rod 212 are in the folded state, the first bracket 1 is in the vertical state, and the second bracket 2 is closely attached to and parallel to the first bracket 1. At this time, the plasma arc gun is oriented vertically downward. In this state, the workpiece is placed on another object, not the support base 4.
[0051] Reference Figure 5 When the first rod 111 and the second rod 112 are in a folded state, and the third rod 211 and the fourth rod 212 are in an unfolded state, the first bracket 1 is in a flat state, and the second bracket 2 is in a vertical state, and the plasma arc gun is oriented vertically upward. In this state, the workpiece is placed on a separate object, specifically, the workpiece is located above the plasma arc gun, not the support base 4.
[0052] In summary, the installation and debugging bracket of the plasma arc gun can quickly adjust the direction of the plasma arc gun, thereby facilitating the debugging of the plasma arc gun. There is no need to disassemble the plasma arc gun during the adjustment process, and it is more convenient to use.
[0053] Embodiment 2:
[0054] Reference Figure 6 A mounting and debugging bracket for a plasma arc gun, the difference between the second embodiment and the first embodiment is that a movable caster 101 is arranged at the bottom of the base frame 10, and a plurality of movable casters 101 are provided to facilitate personnel to push the base frame 10 to move, so as to facilitate the debugging of the plasma arc gun.
[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
