DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1 , Figure 2 , a welding positioning device for a speaker T-iron shown in the figure includes a conveyor belt 1, a frame 2 is installed on the outer side of the conveyor belt 1, and a positioning structure 3 for positioning the T-iron raw material. A plurality of positioning structures 3 distributed at equal distances are fixedly installed on the conveyor belt 1, and the positioning structure 3 includes a tray 301, and two symmetrically distributed positioning blocks 302 are installed on the upper side of the tray 301, and the shape of the positioning blocks 302 is "V" shaped; a locking component 5 is used to position the positioning blocks 302, and the locking component 5 is installed inside the positioning structure 3; a stopper bar 7 is used to drive the two positioning blocks 302 to approach each other, and the two symmetrically distributed stopper bars 7 are installed on the upper side of the conveyor belt 1; a stopper bar 2 8 is used to drive the two positioning blocks 302 away from each other, and the two symmetrically distributed stopper bars 2 8 are installed on the upper side of the conveyor belt 1 and are located on the left side of the stopper bar 7, and the lower ends of the stopper bars 7 and the stopper bars 2 are fixedly connected with a fixing plate 9, and the fixing plate 9 is fixedly connected to the frame 2.

[0024] See also Figure 3Two symmetrically distributed limit sliders 303 are movably embedded inside the pallet 301, and the positioning block 302 is fixedly connected to the limit slider 303 through a connecting column. A baffle 304 is fixedly embedded at the center of the lower end of the limit slider 303. The limit slider 303 can prevent the positioning block 302 from separating from the pallet 301. Limiting straight grooves 305 are provided on the pallet 301 and the anti-slide plate 4, and the connecting column, the limit slider 303 and the baffle 304 are in sliding contact with the pallet 301 and the anti-slide plate 4 through the limiting straight grooves 305. A support seat 306 is fixedly embedded at the center of the lower end of the pallet 301, and the support seat 306 is fixedly connected to the conveyor belt 1 through fixing screws. The support seat 306 is used to separate the pallet 301 and the conveyor belt 1.

[0025] The working principle of automatically positioning the T-iron raw material is as follows: a person places the T-iron raw material on the pallet 301 at the right end of the conveyor belt 1. When the conveyor belt 1 transports the positioning structure 3 to the two baffle bars 7, the two baffle bars 304 in the positioning structure 3 press against the opposite sides of the two baffle bars 7, so that during the movement of the positioning structure 3, the two baffle bars 7 drive the two "V"-shaped positioning blocks 302 to approach each other through the baffle bars 304, so that the round T-iron raw material can be positioned at the center of the pallet 301. When the conveyor belt 1 transports the positioning structure 3 to the baffle bar 28, the two baffle bars 304 press against the two baffle bars 7. The two baffle bars 28 are away from one side, so that when the positioning structure 3 moves, the two baffle bars 28 drive the two positioning blocks 302 to move away from each other through the baffle rod 304. At this time, the robot arm of the welding machine can directly grab the T-iron raw material positioned at the center of the pallet 301, and then when the conveyor belt 1 transports the positioning structure 3 to the right end of the frame 2, the two positioning blocks 302 still remain away from each other, which is convenient for personnel to place the T-iron raw material on the pallet 301. Personnel only need to place the T-iron raw material on the pallet 301 without performing other operations, which can effectively improve the processing efficiency of the T-iron welding production line.

[0026] Embodiment 2

[0027] See also Figure 4 This embodiment further explains Example 1. The locking assembly 5 includes two locking rods 501 movably embedded in the outer side of the limiting slider 303, and the two locking rods 501 are symmetrically distributed. A hemispherical portion is provided at one end of the locking rod 501 away from the limiting slider 303. The hemispherical portion of the locking rod 501 can reduce the friction between it and the tray 301.

[0028] See also Figure 3 , Figure 4The two locking rods 501 are fixedly connected with a gasket 502 at one end close to each other. The gasket 502 can prevent the locking rod 501 from detaching from the limiting slider 303. A spring 503 is installed between the two gaskets 502 and inside the limiting slider 303. The two ends of the spring 503 are respectively movably abutted against the two gaskets 502. The spring 503 can drive the two locking rods 501 to move. Two rows of spherical slots 6 are provided on the inner side of the limiting straight groove 305, and the hemispherical part of the locking rod 501 is movably engaged with the tray 301 through the spherical slot 6.

[0029] In this embodiment: in the process that the two baffle bars 1 7 drive the two positioning blocks 302 to approach each other, and the two baffle bars 2 8 drive the two positioning blocks 302 to move away from each other, the locking rod 501 in the locking assembly will be driven by the compression force of the spring 503 to snap into the corresponding spherical slot 6, thereby locking the positions of the two positioning blocks 302, which can effectively prevent the T-iron raw material from being displaced during the process of the conveyor belt 1 transporting the positioning structure 3 and the T-iron raw material.

[0030] Embodiment 3

[0031] See also Figure 4 This embodiment further illustrates other embodiments. An anti-skid plate 4 is fixedly installed on the upper end of the tray 301 . The anti-skid plate 4 can prevent the T-iron raw material from moving on the tray 301 .

[0032] In this embodiment: when the two positioning blocks 302 in the positioning structure 3 move away from each other under the drive of the baffle bar 8, and the locking rod 501 is embedded in the spherical groove 6, since the T-iron raw material is placed on the anti-slip plate 4, the friction between the anti-slip plate 4 and the T-iron raw material ensures that at the moment when the hemispherical part of the locking rod 501 is embedded in the spherical groove 6, the T-iron raw material will not be displaced on the anti-slip plate 4, which can effectively prevent the locking structure 5 from affecting the position of the T-iron raw material.
