[0018] The present utility model will be further described below in conjunction with the accompanying drawings:

[0019] Referring to the accompanying drawings: This integrated welding tongs turntable includes an outer disc 1 and an inner disc 2. The inner disc 2 is coaxially arranged inside the outer disc 1. An installation spacing 3 is formed between the outer disc 1 and the inner disc 2. A pressure disc 4 fixed to the outer disc 1 by bolts is arranged in the installation spacing 3. A first raceway 21 is arranged on the outer peripheral surface of the inner disc 2. A second raceway 41 is arranged on the outer peripheral surface of the pressure disc 4. The first raceway 21 and the second raceway 41 are spliced with each other to form a ball groove 5. A number of steel balls 6 are filled in the ball groove 5. A locking mechanism 7 is arranged on the inner disc 2. The locking mechanism 7 acts on the end surface of the pressure disc 4 to prevent or not prevent the inner disc 2 from rotating when locked or unlocked. The principle of the present utility model is that the inner disc 2 (for installing the welding tongs) is coaxially placed inside the outer disc 1, and the steel balls 6 are placed in the ball groove 5 to increase the smoothness of the inner disc 2 during rotation. On the one hand, the pressure disc 4 confines the steel balls 6 in the ball groove 5 formed by the first raceway 21 and the second raceway 41. On the other hand, the pressure disc 4 confines the inner disc 2 inside the outer disc 1, which has the advantages of simple structure, convenient assembly, and flexible rotation. The locking mechanism 7 can prevent the inner disc 2 from continuing to rotate after the welding tongs are adjusted to the required use angle by the rotation of the inner disc 2. In this way, it does not need to rely on manual control, which also reduces the fatigue of the user during use and improves work efficiency.

[0020] A connecting strip 61 is arranged between adjacent steel balls 6. Such a setting enables a number of steel balls 6 to form a bead string matching the configuration of the first raceway 21 or the second raceway 41, so that the steel balls 6 do not need to be placed one by one when placed in the ball groove 5, thereby improving the assembly convenience.

[0021] The locking mechanism 7 includes two locking blocks 71 respectively located above and below the inner disc 2, and an adjustable handle 72. The locking block 71 located below the inner disc 2 is in threaded engagement with the threaded section of the adjustable handle 72, and the locking block 71 located above the inner disc 2 has a clearance fit with the smooth rod section of the adjustable handle 72. The smooth rod section of the adjustable handle 72 has a clearance fit with the inner disc 2, and it is allowed that when the adjustable handle 72 rotates in the locking direction or the unlocking direction, the locking block 71 located below moves closer to or away from the pressure plate 4 under the action of the threaded engagement. When the locking block 71 located above abuts against the pressure plate 4, it generates a clamping force on the pressure plate 4 together with the locking block 71 located below. Such a setting is not only convenient to operate, but also has a strong clamping force. That is, the clamping force of the two locking blocks 71 can be adjusted by rotating the adjustable handle 72. When the adjustable handle 72 rotates, the locking block 71 located below the inner disc 2 realizes up and down movement by using its threaded engagement with the adjustable handle 72. Moving up means moving towards the pressure plate 4, and moving down means moving away from the pressure plate 4. When it abuts against the pressure plate 4, it can generate a clamping force on the pressure plate 4 together with the locking block 71 located above, and also generates a frictional force through the clamping force, and relies on the frictional force to prevent the rotation of the inner disc 2.

[0022] The locking block 71 includes a block body 71-1 and a wooden block 71-2. The block body 71-1 has a rectangular section and a trapezoidal section. On the rectangular section, there are two first counterbores 71-11 distributed in a triangular shape and a handle connection hole 71-12. Inside the large-diameter end of the first counterbore 71-11, there is a cylindrical pin 8 and a spring 9 sleeved outside the cylindrical pin 8. The cylindrical pin 8 is inserted into the inner disk 2 and is in interference fit with it. One end of the spring 9 is supported on the end face of the large-diameter end of the first counterbore 71-11, and the other end is supported on the end face of the inner disk 2. The handle connection hole 71-12 is a threaded hole and is threadedly connected to the threaded section of the adjustable handle 72. On the trapezoidal section, there is a second counterbore 71-13. A set screw 10 is threadedly connected to the small-diameter section of the second counterbore 71-13, and the large-diameter end is used to set the wooden block 71-2 connected to the set screw 10. The wooden block 71-2 abuts against the pressure plate 4 when the locking mechanism 7 is in the locked state. The block body 71-1 utilizes the multiple functional holes provided on itself, so that the block body 71-1 can not only achieve the cooperation with the cylindrical pin 8, but also achieve the cooperation with the adjustable handle 72, and can also set the wooden block 71-2. The setting of the two first counterbores 71-11 means that there are also two cylindrical pins 8 that cooperate with them. This can prevent the locking block 71 that is threadedly engaged with the adjustable handle 72 from following the rotation when the adjustable handle 72 rotates, and can realize the movement of the locking block 71. The function of the wooden block 71-2 is that when it is pressed against the pressure plate 4, it can generate frictional force. After combining with the pressing force, it can prevent the rotation of the inner disk 2. The spring 9 is used to assist the locking block 71 to move in the direction away from the inner disk 2 or the pressure plate 4, so that there is a spacing between the wooden block 71-2 and the pressure plate 4, thereby releasing the pressing force and the frictional force and enabling the inner disk 2 to resume rotation.

[0023] The handle connection hole 71-12 of the locking block 71 located above and distributed in a triangular shape with the two first counterbores 71-11 is a through hole, realizing the clearance fit between the adjustable handle 72 and the handle connection hole 71-12, and also facilitating the rotation of the adjustable handle 72 in the handle connection hole 71-12, and this locking block 71 will not move like the locking block 71 located below.

[0024] The adjustable handle 72 is formed with a stepped structure 72-1 that keeps it on the locking block 71 located above, that is, the adjustable handle 72 can always be kept on the locking block 71 located above by using the stepped structure 72-1, and the holding section of the adjustable handle 72 will not come into contact with the set screw 10, that is, it will not affect the rotation of the adjustable handle 72.

[0025] A relief channel 21 is provided at the central position of the inner disk 2. The relief channel 21 facilitates the passage of wires and components of the welding tongs itself when the welding tongs are arranged on the inner disk 2, facilitating the installation of the welding tongs.

[0026] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and detail may be made within the scope of the claims.
