[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a cross-bar weld grinding production line, comprising a processing table, wherein a welding conveying mechanism, a grinding conveying mechanism, and a material receiving mechanism are respectively provided on the surface of the processing table, a buffer table is provided between the welding conveying mechanism and the grinding conveying mechanism, the welding conveying mechanism comprises two first transmission rollers, the first transmission rollers are rotatably connected to the side wall of the processing table, the surfaces of the two first transmission rollers are jointly connected to a first conveyor belt, an end of one of the first transmission rollers is connected to a first motor, and the first motor is fixedly connected to the side wall of the processing table;

[0007] The grinding conveying mechanism includes two second transmission rollers, which are rotatably connected to the side wall of the processing table. The surfaces of the two second transmission rollers are commonly connected to a second conveyor belt, and one end of the second transmission rollers is connected to a second motor, which is fixedly connected to the side wall of the processing table.

[0008] The buffer table is fixedly connected to the side wall of the processing table, and the two ends of the buffer table are respectively slidably connected to the ends of the first conveyor belt and the second conveyor belt;

[0009] The surfaces of the first conveyor belt, the buffer table and the second conveyor table are symmetrically and slidably connected to a conveyor frame, and the conveyor frames are respectively fixedly connected to the side walls of the processing table.

This technical solution can solve the above problem. The specific operation is as follows: first, the two parts to be welded are placed crosswise in the semi-clamping mechanism, and the parts to be welded are stabilized by the semi-clamping mechanism.

Until the next semi-clamping mechanism drives the parts to be welded to the welding station, the first motor is turned off to complete the above work until The mounting plate at the far right end of the buffer table surface is squeezed onto the surface of the second conveyor belt, and then the second motor is turned on to make the conveyor belt of the second motor transmit to the right. After the welded parts are transported to the grinding station, the second motor is turned off and the semi-clamping mechanism is manually adjusted to completely clamp the parts to be ground, so as to avoid the problem of shaking of the parts to be ground during grinding, thereby improving the stability of the parts during grinding. When the grinding is completed, the second motor is turned on again to continue to transport the polished parts to the right through the second conveyor belt.

The ends of the longitudinal clamping blocks 15 are provided with longitudinal clamping grooves 17 that are adapted to the parts to be welded. The tops of the longitudinal clamping blocks 15 are fixedly connected with second slide bars 18, and the surfaces of the second slide bars 18 are slidably connected with transverse clamping blocks 19. The surfaces of the second slide bars 18 are sleeved with second return springs 20, and the two ends of the second return springs 20 are respectively fixedly connected to the longitudinal clamping blocks 15 and the transverse clamping blocks 19. The inner sides of the transverse clamping blocks 19 are provided with longitudinal clamping grooves that are adapted to the parts to be welded. The connecting piece is adapted to the transverse clamping groove 21, and the top of the processing table 1 is located at the first conveyor belt 4 and the second conveyor belt 7, respectively, and a pushing mechanism for pushing the transverse clamping open and the longitudinal clamping block 15 is provided; the pushing mechanism includes a first magnetic block 22 and a second magnetic block 23, the first magnetic block 22 is fixedly connected to the outer wall of the longitudinal clamping block 15, and the second magnetic block 23 is fixedly connected to the end of the transverse clamping block 19. The top of the processing table 1 is symmetrically fixedly connected to a plurality of support rods 24, and the surfaces of the plurality of support rods 24 are commonly fixedly connected to a U-shaped pushing frame 25.
