The main shaft is connected with the output shaft of the main shaft box, the tail needle is arranged on the other end of the main shaft through a moving device, and the processing tool holder is arranged beside the main shaft through another transverse moving device. When in use, the worker manually installs the sand roller on the main shaft, then manually moves the tail needle to fix the sand roller, and finally uses the outer circle processing tool or the spiral groove processing tool to process the sand roller. After the processing is completed, the worker needs to manually take down the sand roller from the main shaft. The sand roller processing equipment has rich functions, can not only realize the processing of the sand roller outer circle, but also realize the processing of the spiral groove, effectively reduces the labor intensity of the worker, and improves the production efficiency. However, the disassembly of the sand roller is still completed manually by the worker, and the sand roller usually has a large weight.

[0004] The above technical purpose of the present application is realized by the following technical scheme:

[0005] The automatic feeding and discharging device for sand roller processing machine tool comprises a support, a first track perpendicular to a main shaft of the sand roller processing machine tool and a second track parallel to the main shaft are arranged on the top of the support, a sand roller storage rack or a sand roller conveying device is arranged below the outer end of the first track, a plurality of vertically arranged sand rollers are uniformly distributed on the sand roller storage rack and the sand roller conveying device, a first moving device is arranged on the first track and can move along the first track, a telescopic air cylinder is vertically fixed on the first moving device, an inner supporting clamping mechanism for the upper end hole of the sand roller is arranged at the lower end of the telescopic rod of the telescopic air cylinder, a second moving device is arranged on the second track and can move along the second track, a clamping lifting and overturning device composed of a first servo motor, a lifting air cylinder, a vertical rotating piece, a first clamping air cylinder and a second servo motor is arranged on the second moving device, the first servo motor is fixed on the second moving device through the lifting air cylinder, the upper end of the vertical rotating piece is connected with the driving shaft of the first servo motor, the first clamping air cylinder and the second servo motor are arranged on the two sides corresponding to the lower end of the vertical rotating piece respectively, and the second servo motor can drive the two clamping blocks of the first clamping air cylinder to be horizontally arranged and vertically arranged.

[0006] By adopting the above technical scheme, the sand roller automatic feeding and discharging device matched with the traditional sand roller processing machine tool is provided. The automatic feeding and discharging device first adopts the inner supporting clamping mechanism to vertically clamp and horizontally convey the vertically arranged sand roller, then transfers the sand roller to the clamping lifting and overturning device to adjust the sand roller to the position coaxial with the main shaft of the sand roller processing machine tool, and finally conveys the sand roller horizontally to sleeve the sand roller on the main shaft, so that the automatic feeding of the sand roller is realized, and the above steps are reversed to realize the automatic discharging. The automatic feeding and discharging device creatively adopts the combination of the inner supporting clamping mechanism and the clamping lifting and overturning device, can stably, reliably and conveniently realize the automatic feeding and discharging of the sand roller, and can greatly reduce the labor intensity of workers, improve the production efficiency and improve the safety factor.

[0009] The application further provides that the horizontal height of the second clamping air cylinder is lower than that of the first clamping air cylinder.

[0010] By adopting the technical scheme, the second clamping cylinder is arranged lower than the first clamping cylinder, so that the first moving device and the clamping lifting and overturning device on the second moving device can smoothly transfer the sand roll.

[0011] Further, the inner supporting clamping mechanism comprises a housing, a base, swing fingers and a swing finger driving mechanism, an inner sunken annular boss is arranged at an outer orifice of the through hole in the middle of the base, arc-shaped teeth are arranged on the arc surface of the outer circle of the hinge joint points of the swing fingers, the swing finger driving mechanism comprises a driving cylinder coaxially arranged with the through hole in the middle of the base and a push column, the circumferential surface of the end of the push column away from the driving cylinder is provided with axial teeth engaged with the arc-shaped teeth.

[0018] By adopting the technical scheme, when the swing finger swings outward to the maximum position, the bevel surface on the outer side of the outer end of the swing finger has good adhesion with the inner wall of the workpiece, and the wear-resistant rubber pad on the bevel surface can avoid hard contact between the swing finger and the sand roll, thereby preventing damage to the sand roll, which not only improves the firmness of clamping the workpiece, but also effectively avoids damage to the sand roll, thereby ensuring the quality of the sand roll.

[0019] The main beneficial effects of the present application are:

[0020] 1. The automatic loading and unloading device of this invention creatively adopts the combination of an internal support clamping mechanism and a clamping lifting and turning device, which can stably, reliably and conveniently realize the automatic loading and unloading operation of sand rollers, which can greatly reduce the labor intensity of workers, improve production efficiency and increase the safety factor.
