[0022] As Figures 1 to 3 shown, a double-column type welding positioner includes a support box body 1 and shock-absorbing bases 2 fixedly arranged at both ends above it. A main support column 11 is fixedly arranged on the shock-absorbing base 2. An adjustable support column 12 is slidably connected and installed above the main support column 11. The upper end of the adjustable support column 12 is fixedly connected to a support fixing plate 13. Height adjustment hydraulic cylinders 14 are installed between the support fixing plates 13 on both sides of the adjustable support column 12 and the shock-absorbing base 2. A main power box 3 is installed on the support fixing plate 13 at one end of the support box body 1, and a stable support box 7 is installed on the support fixing plate 13 at the other end. Rotating discs 8 are arranged on the opposite surfaces of the main power box 3 and the stable support box 7. Bracket plate fixing seats 6 are fixedly arranged on the rotating discs 8. A fixing bracket plate 10 is installed between the bracket plate fixing seats 6. A distance measuring sensor 18 is installed below the support fixing plate 13, and a control box 5 is installed on the outer side wall of the main power box 3.

[0023] Among them, operation buttons 16 are arranged on the control box 5. A display screen 17 is arranged below the operation buttons 16. An adjustment motor 4 is installed at the outer end of the main power box 3. The main shaft of the adjustment motor 4 is connected to the rotating disc 8 on the main power box 3 through a transmission structure. The adjustment motor 4 is used to provide power support for the rotation of the rotating disc 8.

[0024] Four height-adjusting hydraulic cylinders 14 are provided, and the four height-adjusting hydraulic cylinders 14 expand and contract synchronously to realize the telescopic adjustment of the adjustable support column 12.

[0025] A cavity adapted to the lower end of the adjustable support column 12 is provided inside the main support column 11. A locking set screw 15 is installed on the outer side of the main support column 11 by threaded connection. The relative position of the adjustable support column 12 and the main support column 11 can be locked by the locking set screw 15.

[0026] The bracket plate fixing seats 6 on the driving power box 3 and the bracket plate fixing seats 6 on the stable support box 7 are symmetrical to each other. The bracket plate fixing seat 6 is of a U-shaped structure, and a clamping groove 19 is formed in the inner cavity. A fixing screw 9 is installed on the top surface of the bracket plate fixing seat 6 by threaded connection. A support pad 20 is arranged on the supporting surface in the clamping groove 19 of the bracket plate fixing seat 6 for support and protection.

[0027] The fixed bracket plate 10 is of a frame structure, and fixed mounting holes 21 are machined on the fixed bracket plate 10 for fixing the parts to be welded on the fixed bracket plate 10.

[0028] The working principle of the present utility model is:

[0029] Embodiment 1: When there are many product specifications for welding and the sizes vary greatly, the height-adjusting hydraulic cylinder 14 can be telescopically adjusted to drive the telescopic movement of the adjustable support column 12, and then adjust the height positions of the support fixing plate 13, the driving power box 3, the stable support box 7, and the bracket plate fixing seat 6, so that the fixed bracket plate 10 with a larger size specification has sufficient rotational adjustment space;

[0030] When fixing and installing the parts to be welded, the telescopic rod of the height-adjusting hydraulic cylinder 14 contracts, driving the support fixing plate 13 to move downward, and then the adjustable support column 12 contracts into the main support column 11. The height positions of the bracket plate fixing seat 6 and the fixed support plate also decrease, facilitating the fixed installation of the parts to be welded. After the parts to be welded are fixed, the height-adjusting hydraulic cylinder 14 extends to an appropriate height position to ensure that the distance between the center of the rotating disc 8 and the top surface of the support box body 1 is greater than the rotation radius of the fixed bracket plate 10 to avoid interference. The height position is monitored by the distance measuring sensor 18;

[0031] The four height-adjusting hydraulic cylinders 14 expand and contract synchronously. Components such as an oil tank, an oil pump, and connecting pipes are arranged inside the support box body 1; an angular displacement sensor is arranged on the transmission structure of the adjusting motor 4 to accurately control the adjustment accuracy of the positioner;

[0032] Embodiment 2: If the welding product specifications are few and the size specifications are relatively small within a certain time period of the user unit, or only products of one specification are processed during a certain period, it is possible to choose to lock the positions of the adjustable support column 12 and the main support column 11 using the locking set screw 15 to support and protect the height adjustment hydraulic cylinder 14, effectively extending the service life of the height adjustment hydraulic cylinder 14;

[0033] The main support column 11 and the adjustable support column 12 are both provided below the driving power box 3 and the stable support box 7 of the double-column type welding positioner of the present utility model. The support height of the adjustable support column 12 can be adjusted by the height adjustment hydraulic cylinder 14, which can meet the rotational adjustment use requirements of the fixed support plate 10 of different size specifications. The fixed support plate 10 is fixed to the support plate fixing seat 6 through the fixing screw 9, which is convenient for disassembling, installing, and replacing the fixed support plate 10. The four height adjustment hydraulic cylinders 14 expand and contract synchronously. A distance measuring sensor 18 is provided on the support fixing plate 13, which can monitor the lifting height of the support fixing plate 13 to ensure that the fixed support plate 10 has sufficient rotational adjustment space.

[0034] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art of this patent, without departing from the technical solution of the present utility model, can make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes. However, as long as it does not depart from the technical solution of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the present utility model.
