Description

Technical Field

[0001] The invention belongs to the technical field of grinding, and in particular relates to a grinding device for processing columnar forgings. Background Art

[0002] A forging is an object where metal is subjected to pressure, either plastically deformed to a desired shape or to a suitable compressive force. This force is typically applied by the use of a hammer or a press. The forging process builds a fine grain structure and improves the physical properties of the metal. A correct design will allow the grains to flow in the direction of the main pressure in the actual use of the part. Forgings need to be uniform from piece to piece without any porosity, extra space, inclusions or other imperfections.

[0003] Grinding is similar to "polishing". It is the process of rubbing the surface of a workpiece with friction media such as sandpaper, pumice, and fine stone powder.

[0004] Turning is used for machining external circles, end planes, threads, and internal holes on lathes. It can also be used for grooving and cutting off.

DETAILED DESCRIPTION

[0015] like Figure 1-2 As shown, the present invention provides a grinding device for processing columnar forgings, comprising a shape detection component 1, a selection device 2, an upper conveyor belt 3, an inspection chamber 4 and a grinding component 5 arranged in sequence. When the workpiece passes through the selection device 2, the unqualified workpiece detected by the shape detection component 1 is sent to the upper conveyor belt 3 by the selection device 2 and enters the inspection chamber 4 for secondary inspection, while the qualified workpiece is sent to the lower conveyor belt. The qualified workpiece judged by the inspection chamber 4 and the qualified workpiece on the lower conveyor belt are uniformly placed on the grinding component 5 for grinding.

[0016] Since a step is turned at one end of the columnar forging, the diameter of one end of the columnar forging is smaller than that of the other end. Therefore, when the columnar forging passes through the shape detection component 1, the shape detection component 1 detects whether one end of the workpiece has been turned. If the shape detection component 1 determines that the workpiece has not been turned, the workpiece is an unqualified workpiece and is then sent to the selection device 2. The workpiece determined to have not been turned is sent to the upper conveyor belt 3, and the upper conveyor belt 3 sends the workpiece to the inspection chamber 4. The inspection chamber 4 determines whether the workpiece has not been turned or the directions of the two ends of the workpiece are reversed. If the directions of the two ends of the workpiece are reversed, it is determined to be a qualified workpiece. The qualified workpieces on the upper conveyor belt 3 and the lower conveyor belt are all sent to the grinding component 5 for grinding.

[0017] Please focus on Figure 3The shape detection component 1 includes a conveyor belt, and a slot 101 provided on the conveyor belt, a workpiece is placed on the slot 101, a pillar 102 is provided outside one side of the conveyor belt, a swing column 103 is hinged on the pillar 102 through a hinge rod 104, and a sensor 105 is located above the swing column 103 and installed on the pillar 102; when an unqualified workpiece passes through the pillar 102 via the conveyor belt, the workpiece will push the pillar 102 to rotate around the hinge point, thereby being sensed by the sensor 105, and then transmitting a signal to mark the workpiece as an unqualified workpiece.

[0018] The workpiece is located in the slot 101 and is transported to the shape detection component 1 by the conveyor belt. When an unqualified workpiece passes through the swing column 103, the unturned portion of the workpiece will touch the swing column 103, thereby driving the swing column 103 to rotate around the hinge point, so that the sensor 105 senses the swing column 103, transmits a signal, marks the workpiece, and then the workpiece continues to move forward with the conveyor belt.

[0019] Please focus on Figure 4 The picking device 2 includes a picking conveyor belt, a rotating column 202 movably installed above the picking conveyor belt through a bracket 201, a slave gear is installed on the rotating column 202, and the slave gear is meshed with the main gear for transmission, and the main gear is installed on the motor. At the same time, both ends of the rotating column 202 are movably covered with a moving plate 204 through a cylinder, and positioning spikes 203 are evenly distributed around the axis of the moving plate 204. At the same time, a stopping unit is symmetrically installed on the bracket 201.

[0020] Since the inside of the workpiece is hollow, when it is sensed that an unqualified workpiece passes through the rotating column 202, the cylinder is turned on and the movable plate 204 moves along the length direction of the rotating column 202, so that the positioning tip 203 positions the workpiece and the movable plate 204 clamps the workpiece. At this time, the selection conveyor belt stops transporting, and then the motor is turned on, and the workpiece is driven by the rotating column 202 to rotate, and then the workpiece is rotated to the upper conveyor belt 3. After the workpiece is placed on the upper conveyor belt 3, the cylinder controls the movable plate 204 to move and release the workpiece; if the movable plate 204 does not clamp the workpiece, the blocking unit clamps the workpiece to prevent the workpiece from continuing to move to the lower conveyor belt, and then the selection conveyor belt is reversed for transportation, so that the movable plate 204 clamps the missed workpiece and transports the unqualified workpiece to the upper conveyor belt again.

[0021] The stopping unit includes a positioning seat 206 movably mounted on the bracket 201 through an electric linear guide rail 207 , and a positioning head 205 is mounted on the positioning seat 206 .

[0022] When omission occurs, the electric linear guide rail 207 is turned on, and the positioning head 205 positions the missed unqualified workpiece to prevent the unqualified workpiece from being transported to the lower conveyor belt.

[0023] Please focus on Figure 5The grinding assembly includes a fixed seat 501, a fixed frame 502 installed on the fixed seat 501, a rotating column 506 is covered with a bushing, the bushing is movably installed on the fixed frame 502 through a bearing, a plurality of grooves are evenly arranged around the axis on the rotating column 506, a protrusion is provided on the inner wall of the bushing corresponding to the groove, the protrusion is in the groove, and a driven gear is covered with the bushing, a driving gear is installed on the motor 503, the motor 503 is installed on the fixed frame 502, and the driven gear is meshed with the driving gear for transmission, and at the same time, the bottom end of the rotating column 506 is movably installed on the electric lead screw 504, the electric lead screw 504 is installed on the fixed frame, and a grinding block 505 is installed on the top of the rotating column 506.

[0024] When the qualified workpiece is fixed on the fixed frame 502 by the robot and the workpiece is sleeved on the grinding block 505, the motor 503 is turned on, and the motor 503 drives the active gear to rotate, thereby causing the driven gear to rotate, and then drives the bushing to rotate, and the bushing drives the rotating column 506 to rotate, and the rotating column 506 drives the grinding block 505 to rotate, so that the grinding block 505 grinds the inner wall of the workpiece. At the same time, the electric lead screw 504 is turned on, and the electric lead screw 504 pushes the rotating column 506 to move upward, thereby driving the grinding block 505 to move upward, grinding the inner wall of the entire columnar forging, and then the robot transfers the workpiece to the next process.

[0025] The conveyor belt, the sensor 105, the motor, the cylinder, the picking conveyor belt, the electric linear guide 207, the upper conveyor belt 3, the lower conveyor belt, the detection chamber 4, the manipulator, the motor 503 and the electric lead screw 504 are communicatively coupled to the control panel.

[0026] The control panel contains a PLC controller, which can program the numerical control system. The PLC is used as the central control system, and the touch screen is used to realize the program input and operation control of the whole machine, so as to realize the full automation of the transportation process. The control system can be used as a system that connects various actuators to move according to the logical trajectory, and the actuators can be controlled by programming to run according to the required operation steps.

[0027] Based on the above device, the first embodiment of the present invention also proposes a method for using the above grinding device for processing a columnar forging, comprising the following steps: Step 1: When the cylindrical forging passes through the shape detection component 1, the shape detection component 1 detects whether one end of the workpiece is turned.

If the directions of both ends of the workpiece are reversed, it is determined to be a qualified workpiece; Step 4: The qualified workpieces on the upper conveyor belt 3 and the lower conveyor belt are sent to the grinding assembly 5 by the robot for grinding.

[0028] The device can judge whether the workpiece has been turned. If it has not been turned, it is judged as an unqualified workpiece, and then the inner wall of the qualified workpiece can be polished.
