[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a dual-station welding fixture, including a welding support frame 1, an XY-axis bidirectional moving welding machine 3 is movably arranged inside the welding support frame 1, a fixing block 13 is fixedly connected to the output end of the XY-axis bidirectional moving welding machine 3, a fixing ring 19 is fixedly installed inside the fixing block 13, and a flat threaded disc 17 is rotatably installed inside the fixing block 13 corresponding to the upper part of the fixing ring 19.

[0024] The XY-axis bidirectional moving welding machine 3 is an existing technology that can weld workpieces in two directions.

[0025] Three clamping blocks 18 are slidably disposed on the upper end face of the fixing ring 19.

[0026] Specifically, the upper end face of the fixing ring 19 is provided with three sliding grooves 6, and the bottom end of the clamping block 18 is slidably installed inside the sliding grooves 6.

[0027] Three clamping blocks 18 are evenly distributed around the axis of the fixing ring 19. The clamping blocks 18 are in sliding engagement with the flat threaded disc 17. A knob 16 is rotatably mounted on the upper end face of the fixing block 13.

[0028] The outer side of knob 16 has anti-slip grooves.

[0029] The bottom end of the knob 16 is fixedly connected to the flat threaded disc 17, and the welding head 15 is installed at the upper limit of the opposite ends of the three clamps 18.

[0030] A gas inlet 14 is fixedly connected to the top of the welding head 15, and the gas inlet 14 is connected to the gas pipe on the XY axis bidirectional moving welding machine 3.

[0031] The knob 16, the flat threaded disc 17, and the retaining ring 19 are coaxially arranged. The fixing block 13 has an assembly hole at the axis corresponding to the retaining ring 19, and the welding head 15 is limited and installed in the assembly hole.

[0032] The welding support frame 1 is fixedly equipped with a power circuit breaker 2, a shifting servo motor 4, a material placement tool 5, a displacement thickness measuring mechanism 7, a pressing mechanism cylinder 9, a wiring trough 11, and a welding transformer 12. A data storage display screen 8 is provided on one side of the welding support frame 1.

[0033] like Figure 1 As shown, a movable frame is installed on the welding support frame 1 with left and right limit positions. The displacement servo motor 4 is used to drive the movable frame to move left and right. The XY axis bidirectional moving welding machine 3 is slidably installed on the movable frame. The upper welding cylinder 10 is fixedly installed on the movable frame. The telescopic end of the upper welding cylinder 10 is fixedly connected to the top of the XY axis bidirectional moving welding machine 3. The upper welding cylinder 10 is used to drive the XY axis bidirectional moving welding machine 3 to move up and down.

[0034] The material handling tool 5 is used to place the cylinder head gasket.

[0035] The displacement thickness measuring mechanism 7 detects whether the number of cylinder gaskets is appropriate. The displacement thickness measuring mechanism 7 transmits the data to the data storage display screen 8, which then displays the data. The displacement thickness measuring mechanism 7 is existing technology and will not be described in detail here.

[0036] The cylinder head gasket of the pressing mechanism cylinder 9 is fixed during welding.

[0037] The welding transformer 12 keeps the voltage stable during welding.

[0038] By routing the cables through the wiring trough 11, mechanical damage to the wires and data cables, as well as corrosion from dust and moisture, can be prevented, thereby extending the service life of the cables.

[0039] Working principle:

[0040] During use, the XY-axis bidirectional moving welding machine 3 drives the welding head 15 to move and weld the cylinder head gasket. When the welding head 15 collides with the workpiece or other objects, it will be damaged by a large external impact. At this time, the welding head 15 needs to be replaced to ensure the welding quality.

[0041] When replacing the welding head 15, manually turn the knob 16 counterclockwise. The knob 16 drives the flat threaded disc 17 to rotate. When the flat threaded disc 17 rotates, it drives the three clamping blocks 18 to slide in the sliding groove 6 and move to the outside of the fixing ring 19 at the same time, thus releasing the fixing of the welding head 15.

[0042] After placing the new welding head 15 into the fixing ring 19, turn the knob 16 clockwise. At this time, the knob 16 drives the three clamping blocks 18 to move towards the welding head 15 simultaneously through the flat threaded disc 17, thus tightening the welding head 15. After clamping, the clamping blocks 18 can only slide in the sliding groove 6 and cannot drive the flat threaded disc 17 to rotate, thereby preventing the welding head 15 from loosening. Connect the air pipe on the XY axis bidirectional moving welding machine 3 to the air inlet 14, and it can be used normally.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
