DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figure 1-8 As shown, a welding machine for an upper cover comprises a support base 1;

[0039] A support plate 2 is rotatably mounted on the support seat 1, and at least four positioning blocks 3 are arranged at intervals on the support plate 2. The at least four positioning blocks 3 can jointly form a positioning area with restricted sides, and the top of the positioning area is in an open state;

[0040] The support seat 1 is also provided with a mounting frame 4, on which an up-and-down driving device 5 is mounted, and a welding gun 6 is mounted at the output end of the up-and-down driving device 5;

[0041] A support plate driving assembly is also provided on the support seat 1 , and the support plate driving assembly acts on the support plate 2 , so that: the support plate 2 can rotate, and the welding gun 6 can face the area between any two positioning blocks 3 .

[0042] This embodiment is applicable to Fig. 9 The upper cover shown is shaped into a square shape and has four flanges. The abutting parts of the four flanges need to be welded, that is, the corners of the four flanges need to be welded.

[0043] In this embodiment, the connecting shaft 7 is rotatably mounted on the support seat 1 through the bearing 27. When in use, at least four positioning blocks 3 should be provided, and these at least four positioning blocks 3 can limit the position of the four flanges of the upper cover. Of course, each flange can also be provided with multiple positioning blocks 3 to limit it; then start the support plate drive assembly to drive the support plate 2 to rotate. During the rotation (360° rotation), the four corners of the semi-finished upper cover can face the welding gun 6. When welding, since the corners have a certain height, in addition to starting the welding gun 6, the upper and lower drive devices 5 must be started synchronously so that the welding gun 6 can move up and down to complete the welding. The upper and lower drive devices 5 can use cylinders.

[0044] Among them, by setting the positioning block 3, the upper cover semi-finished product can be quickly positioned so that the corners can be welded by the welding gun, and the upper cover semi-finished product can be prevented from accidentally moving during the rotation process.

[0045] Preferably, the support plate 2 is in a diamond shape;

[0046] Four positioning blocks 3 are provided, and the four positioning blocks 3 are respectively located at the four corners of the two supporting plates.

[0047] In this embodiment, the four positioning blocks 3 can better position the upper cover semi-finished product. When the upper cover semi-finished product is placed on the support plate 2, the four corners of the diamond-shaped support plate 2 and the four corners of the square upper cover semi-finished product are staggered, so that it is convenient to achieve welding processing at the corners, and at the same time, it is also convenient to load and unload the upper cover by holding the corners of the upper cover.

[0048] In order to realize the rotational drive of the support plate 2, preferably, the support plate 2 is rotatably connected to the support seat 1 through a connecting shaft 7;

[0049] The support plate driving assembly includes a rotating driving device 8, a rotating driving wheel 9 sleeved on the output shaft of the rotating driving device 8, and a rotating driven wheel 10 sleeved on the connecting shaft 7;

[0050] The support plate driving assembly also includes a rotating transmission belt 11 sleeved on the rotating driving wheel 9 and the rotating driven wheel 10.

[0051] In this embodiment, the rotation driving device 8 is started to drive the rotation driving wheel 9 to rotate, and the rotation driven wheel 10 can be driven to rotate through the transmission effect of the rotation transmission belt 11, and then the connection shaft 7 and the support plate 2 can be driven to rotate. The rotation driving device 8 can be a reduction motor.

[0052] Preferably, the positioning block 3 includes a positioning section 12 and an adjusting section 13 connected to the positioning section 12, and a strip-shaped opening 14 is formed on the adjusting section 13;

[0053] The support plate 2 is provided with a locking hole 31;

[0054] A locking piece is also included, and the bottom end of the locking piece passes through the strip-shaped opening 14 and is connected to the locking hole 31 .

[0055] In this embodiment, by adjusting the position of the positioning block 3 relative to the locking hole 31, the length of the four sides limited by the positioning area can be adjusted. In this way, it can be applied to upper cover semi-finished products of different specifications. The locking member 28 can be selected from screws, bolts, etc.

[0056] Preferably, the welding gun 6 is mounted on the output end of the upper and lower driving device 5 via a connecting frame 19;

[0057] A welding gun limiting slide groove 20 is provided on the connecting frame 19 , and a welding gun limiting slide rail 21 which can cooperate with the welding gun limiting slide groove 20 is installed on the mounting frame 4 .

[0058] In this embodiment, the cooperation between the welding gun limiting slide groove 20 and the welding gun limiting slide rail 21 can improve the stability of the welding gun 6 moving up and down, thereby improving the welding quality.

[0059] Furthermore, at least one set of through-hole components is provided on the support plate 2, and each set of through-hole components includes two through-holes 15 penetrating the upper and lower ends thereof;

[0060] Also included is an upper top assembly;

[0061] The lifting assembly includes a lifting drive device 16, the output end of the lifting drive device 16 is connected to a lifting connection frame 17, and both ends of the lifting connection frame 17 are provided with lifting rods 18;

[0062] The lifting driving device 16 acts on the lifting connecting frame 17 so that the two lifting rods 18 can respectively pass through the two through-openings 15 of the same through-opening assembly.

[0063] In this embodiment, in order to make way for the connecting shaft 7, a middle portion of the upper connecting frame 17 has a making way opening 26.

[0064] When this embodiment is used, the upper connecting frame 17 can be driven to move up and down by starting the upper driving device. When unloading is required, the upper connecting frame 17 is moved upward so that the upper rod 18 can pass through the through hole 15 to act on the bottom end of the upper cover and drive the upper cover to move upward together, so that it is convenient for operators to remove the upper cover. Among them, the upper driving device 16 can be a cylinder. In order to improve the stability of the upper connecting frame 17 moving drive, two upper driving devices 16 can be provided to act on the upper connecting frame 17.

[0065] When the design has a set of through-port components, such as Figure 7 As shown, that is, when only two through-holes 15 are provided on the support plate 2, the upper cover needs to be reset to the initial position after completing the welding process of the four corners, that is, it needs to be reset to the angle position where the first corner faces the welding gun 6. In this way, each time welding is completed, the support plate 2 rotates 360°, and when unloading, even if only one set of through-hole components is provided, the two upper ejector rods 18 can face the two through-holes 15.

[0066] If the upper cover is being cut, the welding gun 6 is facing the last corner, then each time welding is completed, the support plate 2 only needs to rotate 270°. To make up for the angle difference, two sets of through-hole components need to be provided on the support plate 2. The four through-holes 15 in the two sets of through-hole components are evenly distributed on the loop, that is, two adjacent through-holes 15 are spaced 90° apart. Figure 8 As shown, in this way, even if there is an angle difference, the lifting requirement of the upper push rod 18 can still be met.

[0067] Preferably, the upper connecting frame 17 is provided with an upper push rod limiting cylinder 22;

[0068] The support seat 1 is provided with an upper push rod limiting guide rod 23 which can cooperate with the upper push rod limiting cylinder 22 .

[0069] In this embodiment, the cooperation between the upper push rod limiting cylinder 22 and the upper push rod limiting guide rod 23 can improve the stability of the upper push rod connecting frame 17 moving up and down. In order to improve the stability of the rotation of the support plate 2, the top of the upper push rod limiting guide rod 23 can be provided with a support section 24, and the top of the support section 24 is inlaid with a ball 25, which can reduce the friction between the support plate 2 and the support section 24 during relative rotation, thereby improving the service life.
