DETAILED DESCRIPTION

[0022] 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 in 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.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] A welding workstation turntable comprises a base 1, a bearing seat 2 is fixedly installed on the upper surface of the base 1, a rotating shaft 3 is rotatably installed in the bearing seat 2, a main beam 6 is fixedly installed on the upper surface of the rotating shaft 3, a protective plate 61 is fixedly installed on the upper surface of the main beam 6, L-shaped corner seats 7 are adjustable on the front and rear surfaces of the left and right ends of the main beam 6, an auxiliary beam 8 is detachably installed between the lower surfaces of the two corresponding front and rear corner seats 7, a fixture is installed between the ends of the two auxiliary beams 8, and a plurality of connecting rods are penetrated through the outer surfaces of the left and right ends of the main beam 6 A long-rod bolt 621 is installed between the angle seat 7 and the corresponding connection hole A62, a plurality of connection holes B71 are penetrated through the upper surface of the angle seat 7, a short-rod bolt 711 is installed between the auxiliary crossbeam 8 and the corresponding connection hole B71, and a positioning mechanism 4 and a driving mechanism 5 are installed between the rotating shaft 3 and the bearing seat 2. When the turntable of the welding workstation is in use, the driving mechanism 5 drives the rotating shaft 3 to rotate, thereby adjusting the angles of the main crossbeam 6 and the auxiliary crossbeam 8. Before and after the adjustment, the positioning mechanism 4 can be used to fix the position of the rotating shaft 3;

[0025] When the auxiliary beam 8 needs to be modified, Figure 1 As shown, first remove the short rod bolt 711 installed between the corner seat 7 and the auxiliary beam 8, and then remove the long rod bolt 621 installed between the corner seat 7 and the main beam 6. Subsequently, install the corner seat 7 to the upper surface of the new auxiliary beam 8 through the short rod bolt 711. During installation, it is necessary to pay attention to keeping the distance between the two corner seats 7 at the same position as the width of the main beam 6. Finally, adjust the installation position of the corner seat 7 on the main beam 6 according to the width requirement of the fixture to be installed. After adjusting to the appropriate position, fix the two auxiliary beams 8 with corner seats 7 on the two ends of the main beam 6 with the long rod bolts 621. Compared with the prior art, the turntable of the welding workstation can effectively meet the modification needs, reduce production costs, and improve production efficiency and flexibility.

[0026] It should be noted that if Figure 5 As shown, a transfer groove 22 is provided in the bearing seat 2. Figure 4As shown, the rotating shaft 3 is in an "I" shape, and the bottom end of the rotating shaft 3 is rotatably arranged in the adapter groove 22. The rotating shaft 3 is rotatably connected with the adapter groove 22 through its own "I"-shaped structure to realize rotational installation in the bearing seat 2.

[0027] In order to reduce the friction between the rotating shaft 3 and the bearing seat 2, as Figure 4 As shown, an annular track groove 32 is provided in the bearing seat 2. Figure 4 As shown in Figure 5, the upper surface of the bearing seat 2 is circumferentially equidistantly embedded with multiple load-bearing steel balls 21 for rotation. The load-bearing steel balls 21 are all located in the track grooves 32. The load-bearing steel balls 21 can be used to reduce the contact between the bearing seat 2 and the rotating shaft 3, thereby reducing friction and making the rotation and adjustment of the rotating shaft 3 smoother.

[0028] Specifically, if Figure 3 As shown, a mounting groove is provided on the lower surface of the rotating shaft 3, and the driving mechanism 5 includes a motor 51 and an inner gear ring 52. The motor 51 is fixedly installed in the supporting seat 2, and a gear 53 is sleeved on the outer surface of the output shaft of the motor 51. The inner gear ring 52 is fixedly installed in the mounting groove, and the inner gear ring 52 and the gear 53 are meshingly connected. The motor 51 can drive the rotating shaft 3 to rotate through the linkage of the gear 53 and the inner gear ring 52, thereby driving the main beam 6 and the auxiliary beam 8 to rotate, and then driving the fixture to be installed to rotate, so that the relative position between the product and the welding equipment can be adjusted.

[0029] Specifically, if Figure 3 As shown, a positioning groove 31 is opened in the installation groove, and the positioning mechanism 4 includes a hydraulic telescopic column 41. A positioning block 42 is fixedly installed on the upper surface of the hydraulic telescopic column 41. The positioning block 42 is clamped in the positioning groove 31. The positioning groove 31 is a hexagonal groove, and the positioning block 42 is a hexagonal block. When the clamp installed between the two auxiliary beams 8 is adjusted to the position of the welding equipment, the welding equipment welds the product in the clamp. During welding, in order to avoid the workstation turntable from rotating without authorization and affecting the welding effect, the hydraulic telescopic column 41 can be extended to drive the positioning block 42 to clamp into the positioning groove 31 to fix the position of the rotating shaft 3, thereby keeping the position of the workstation turntable unchanged and ensuring the welding effect. When releasing the positioning of the rotating shaft 3, the hydraulic telescopic column 41 is driven to contract and drive the positioning block 42 to move down and out of the positioning groove 31.

[0030] After long-term use, in order to ensure that the positioning block 42 can still move vertically up and down and accurately snap into the positioning slot 31, Figure 3 As shown, an orientation rod 43 is symmetrically fixedly installed on the lower surface of the positioning block 42, and a shaft sleeve 44 is symmetrically fixedly installed in the bearing seat 2. After the orientation rod 43 is slidably installed in the corresponding shaft sleeve 44, the orientation rod 43 and the shaft sleeve 44 can be used to slide and cooperate with each other to guide the positioning block 42, so that it can be effectively and accurately inserted into the positioning groove 31.
