[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0039] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present utility model: a double-station indexing machine, including a bottom plate 1, a fixed frame 3 is fixedly connected to the rear side of the top wall of the bottom plate 1, an air compressor 4 is fixedly connected to the front side of the left end of the top wall of the bottom plate 1, an output pipe 5 is communicated with the rear end of the air compressor 4, a fixing bolt 6 is fixedly connected to the inner top wall of the bottom plate 1, a connecting block 7 is fixedly connected to the bottom end of the fixing bolt 6, a rotary cylinder 8 is fixedly connected to the bottom end of the connecting block 7, the right end of the output pipe 5 is communicated with the left end of the rotary cylinder 8, a robotic arm 9 is rotatably connected to the bottom end of the rotary cylinder 8, a double-station rotating assembly is arranged in the middle of the top wall of the bottom plate 1, and two turntables 13 are fixedly connected to both the left and right sides of the inner wall of the double-station rotating assembly. A load-carrying frame 14 is fixedly connected between the adjacent front two turntables 13 and the rear two turntables 13. A plurality of clamping mechanisms 2 are arranged on the inner walls of the two load-carrying frames 14;

[0040] Specifically, the bottom plate 1 provides an installation platform for the entire device. The fixed frame 3 located at the rear side thereof strengthens the overall structural stability. The air compressor 4 is located at the front side of the left end of the top wall of the bottom plate 1 and is used to generate compressed gas, which is transported through the output pipe 5 communicated with the rear end to the rotary cylinder 8 fixed by the fixing bolt 6 and the connecting block 7. The robotic arm 9 rotatably connected to the bottom end thereof is driven by high-pressure gas to rotate for grasping, placing and operating workpieces. In the middle of the top wall of the bottom plate 1, planar rotation is performed through the double-station rotating assembly, and the load-carrying frame 14 fixedly connected between the adjacent front and rear turntables 13 on the inner wall changes its position. When the robotic arm 9 completes the operation in one load-carrying frame 14, the double-station rotating assembly quickly rotates the other load-carrying frame 14 carrying unprocessed workpieces to the working position of the robotic arm 9 to continue the operation, greatly improving the work efficiency and realizing double-station continuous operation.

[0041] Referring to Figure 1 , Figure 2 and Figure 4 , the clamping mechanism 2 includes a lead screw 201, a handle 202 is fixedly connected to the top end of the lead screw 201, an extrusion ring 203 is fixedly connected to the bottom end of the handle 202, a pressure plate 204 is rotatably connected to the outer wall of the lead screw 201, a rubber pad 205 is fixedly connected to the bottom wall of the pressure plate 204, a nut 206 is threadedly connected to the bottom end of the outer wall of the lead screw 201, and the nut 206 is fixedly connected to the bottom wall of the load-carrying frame 14;

[0042] Specifically, the clamping position is adjusted by rotating the handle 202 fixedly connected to the top end of the lead screw 201. When the handle 202 rotates, it drives the lead screw 201 to rotate. The outer wall of the lead screw 201 is rotatably connected to the pressure plate 204, and the nut 206 threadedly connected to the bottom end of the outer wall is fixed to the bottom wall of the load frame 14. When the lead screw 201 rotates, due to the fixation of the nut 206, the lead screw 201 will generate displacement in the vertical direction, driving the pressure plate 204 to move downward. The rubber pad 205 fixedly connected to the bottom wall of the pressure plate 204 can provide buffering and increase friction when contacting the object to be clamped, ensuring stable and safe clamping and preventing damage to the surface of the object. For workpieces with a smooth surface, the friction of the rubber pad 205 can effectively prevent the workpiece from sliding. During the clamping process, the extrusion ring 203 increases the connection stability between the handle 202 and the pressure plate 204, preventing the handle 202 from loosening or shifting when rotating, realizing the fixation of workpieces of various shapes and materials, meeting the normal operation requirements of the double-station indexing table.

[0043] Refer to Figure 1 and Figure 3 As shown in and, the double-station rotating assembly includes a rotating motor 10. The rotating motor 10 is fixedly connected to the middle of the top of the bottom plate 1. The output end of the rotating motor 10 is fixedly connected to a rotating fixing plate 11, and the top end of the rotating fixing plate 11 is fixedly connected to an I-shaped frame 12; an electric motor support shell 15 is arranged outside the rotating motor 10. The electric motor support shell 15 is fixedly connected to the top wall of the bottom plate 1, and heat dissipation slots 16 are provided on the outer wall of the electric motor support shell 15; on the front left side of the top wall of the bottom plate 1 near the edge, a table frame 17 is fixedly connected, and a control bar 18 is fixedly connected to the top wall of the table frame 17;

[0044] Specifically, the rotating motor 10 in the double-station rotating assembly provides power for the double-station rotating assembly. Through the rotating fixing plate 11 and the I-shaped frame 12 fixedly connected to its output end, precise rotation switching of the workstations is realized, improving work efficiency and continuity. The electric motor support shell 15 provides protection for the rotating motor 10, and the heat dissipation slots 16 provided on its outer wall help to dissipate the heat generated when the motor works. The control bar 18 is connected to the bottom plate 1 through the table frame 17 at the bottom, and the table frame 17 provides a suitable height for the control bar 18 so that the operator can conveniently operate the control bar 18.

[0045] Refer to Figure 1 and Figure 5 As shown in and, a plurality of display screens 19 are fixedly connected to the top of the control bar 18, and a plurality of control buttons 20 are fixedly connected to the front side of the control bar 18; a load pressure gauge 21 is fixedly connected to the left side of the top wall of the I-shaped frame 12, and the load pressure gauge 21 is electrically connected to the plurality of control buttons 20; a plurality of lighting lamps 22 are fixedly connected to the upper middle part of the rear side of the inner wall of the fixed frame 3, and the plurality of lighting lamps 22 are respectively electrically connected to the plurality of control buttons 20;

[0046] Specifically, the control button 20 at the top of the control bar 18 is used to control the operating status of the entire positioner. The display screen 19 can display the operating parameters of the equipment in real time, which is convenient for the operator to monitor and adjust. The load pressure gauge 21 can measure the load condition in the loading frame 14 so that the operator can adjust the operation according to the load. Multiple lighting lamps 22 in the middle and upper part of the rear side of the inner wall of the fixed frame 3 provide lighting in insufficient light to ensure that the operator can clearly observe the working condition of the positioner and ensure the accuracy and safety of the operation.

[0047] Working principle: the bottom plate 1 provides an installation platform for the entire equipment, and the fixed frame 3 located at the rear side thereof strengthens the stability of the overall structure. The air compressor 4 is located at the front side of the left end of the top wall of the bottom plate 1, and is used to generate compressed gas, which is transported to the rotating cylinder 8 fixed by the fixing bolts 6 and the connecting block 7 through the output pipe 5 connected at the rear end. The mechanical arm 9 connected to the bottom end is driven by the high-pressure gas to rotate, so as to grasp, place and operate the workpiece. In the middle of the top wall of the bottom plate 1, the double-station rotating assembly is used for plane rotation, and the loading frame 14 fixedly connected between the two adjacent turntables 13 at the front and rear ends of the inner wall is changed in position. When the mechanical arm 9 completes the operation in one loading frame 14, the double-station rotating assembly quickly rotates the other loading frame 14 carrying the unprocessed workpiece to the working position of the mechanical arm 9 to continue the operation;

[0048] In addition, the clamping position is adjusted by rotating the handle 202 fixedly connected to the top of the screw 201. When the handle 202 rotates, the screw 201 is driven to rotate. The outer wall of the screw 201 is rotatably connected to the pressure plate 204. The nut 206 threadedly connected to the bottom end of the outer wall is fixed to the bottom wall of the object loading frame 14. When the screw 201 rotates, due to the fixation of the nut 206, the screw 201 will be displaced in the vertical direction, driving the pressure plate 204 to move downward. The rubber pad 205 fixedly connected to the bottom wall of the pressure plate 204 can provide buffering and increase friction when contacting the clamped object, ensuring stable and safe clamping and preventing damage to the surface of the object. For workpieces with smooth surfaces, the friction of the rubber pad 205 can effectively prevent the workpiece from sliding. During the clamping process, the extrusion ring 203 increases the connection stability between the handle 202 and the pressure plate 204 to prevent the handle 202 from loosening or offsetting when it rotates.
