Feeding and discharging mechanism for punching
Technical Field
The utility model relates to bearing machining, in particular to a punching feeding and discharging mechanism.
Background
The inner ring and the outer ring of the bearing are generally processed and finished by cylindrical blanks through the procedures of heating, upsetting, punching, reaming and diameter adjustment. In the punching process, the heated and upsetted cylindrical blank is required to be placed on a punching machine, and the cylindrical blank is required to be taken down from the punching machine after the punching is completed, namely, the cylindrical blank is fed and discharged. Referring to fig. 1, loading and unloading are generally performed by a conveyor module, a blocking portion and two manipulators. Namely, the conveyor belt module is used for receiving the cylindrical blank finished in the previous step and driving the cylindrical blank to move. The blocking part is used for blocking the cylindrical blank and enabling the cylindrical blank to be static relative to the conveyor belt module. A robot is used to place the cylindrical blanks from the conveyor belt module to the press. The other manipulator is used for returning the cylindrical blank from the punching machine to the conveyor belt module, and the returned position passes through the blocking part, so that the cylindrical blank can continue to move along with the conveyor belt module. The existing feeding and discharging mechanism has the problems that two manipulators are adopted, the cost is high, and the installation and adjustment requirements are high.

Referring to fig. 2 and 3, a punching feeding and blanking mechanism includes a conveyor belt module 1, a mounting portion 2, a manipulator 3, a blocking portion 4 and a second driving mechanism 5.
The conveyor belt module 1 is of prior art and only one segment is shown as an illustration in the drawing. For the process of punching the workpiece 6 in the bearing processing, the workpiece 6 is heated at a high temperature before punching, and correspondingly, the conveyor belt in the conveyor belt module 1 can adopt a metal chain plate type. The upper part of the conveyor belt in the conveyor belt module 1 is horizontal for placing the workpieces 6. The placed work pieces 6 move along with the upper belt body of the conveyor belt.
Referring to fig. 2 and 4, the mounting portion 2 is located on a first side of the conveyor module 1, and the punching machine is located on a second side opposite to the first side of the conveyor module 1 when the punching machine is matched with the punching machine. The mounting portion 2 includes a base 2a, a mounting platform 2b, and a first drive 2c. The base 2a is placed on the ground. The mounting platform 2b is connected to the base 2a in a vertically sliding manner. The first driving device 2c is used for driving the mounting platform 2b to move, and specifically, the first driving device 2c may use an air cylinder.
The manipulator 3 is also in the prior art, and needs to be provided with a clamping jaw part 3a capable of clamping and loosening (used for clamping and loosening the workpiece 6), and the clamping jaw part 3a can also stretch and retract in the horizontal plane (used for driving the workpiece 6 to move horizontally). The specific principle of the clamping and releasing of the clamping jaw part 3a and the specific principle of the telescopic are not repeated. The manipulator 3 is mounted on the mounting platform 2b, i.e. is matched to the movement of the mounting platform 2b, the clamping jaw part 3a of the manipulator 3 can also move up and down, and when the clamping jaw part 3a is in upper limit, the workpiece 6 on the conveyor belt module 1 cannot be interfered.
The specific position of the mounting part 2 is set, for the manipulator 3, the telescopic path of the clamping jaw part 3a passes through the conveyor belt module 1, namely, the clamping jaw part 3a needs to pass through the upper side of the conveyor belt module 1, and in the overlooking direction, the telescopic path of the clamping jaw part 3a and the conveyor belt module 1 form a coincident feeding position. In this way, the workpiece 6 is positioned in the loading position, and the jaw portion 3a of the robot arm 3 can correspond to the workpiece 6, specifically, the jaw portion 3a can correspond to the workpiece 6 in the retracted state. By telescoping in the horizontal plane and moving up and down, the jaw portions 3a can grip the workpiece 6 and leave the conveyor module 1 with the gripped workpiece 6, and put into the press. Similarly, the jaw portions 3a can also return the punched work piece 6 in the press to the loading position of the conveyor module 1.
The blocking part 4 is movably connected to the conveyor belt module 1, and the blocking part 4 is switched between the first position and the second position by movement of the blocking part 4 relative to the conveyor belt module 1. In the first position, the blocking portion 4 is used for blocking the workpiece 6 on the conveyor belt module 1, so that the workpiece 6 is kept in the feeding position. In the second position, the blocking part 4 does not interfere with the movement of the workpiece 6 along with the conveyor belt module 1 in the loading position.
In this way, the conveyor belt module 1 keeps moving during the feeding and discharging processes. The robot 3 feeds and transfers the work piece 6 from the conveyor to the press with the blocking part 4 in the first position. And the manipulator 3 is used for blanking, and the punched workpiece 6 is placed back to the feeding position. After loading or unloading is accomplished, the blocking part 4 switches to the second position, and the workpiece 6 placed back to the loading position can continue to move along with the conveyor belt module 1.
The second driving mechanism 5 is used for driving the blocking part 4 to move. The combination to the blocking part 4 requires two limits, a first position and a second position, so that a cylinder can be used as the second drive 5, which conveniently corresponds to the two limits, which is relatively simple to arrange.
For the specific movement of the blocking portion 4 in the conveyor module 1, the blocking portion 4 may be connected to the conveyor module 1 in a vertically sliding manner. The first position is a lower limit and the second position is an upper limit, i.e. in the second position the workpiece 6 can pass under the blocking part 4. However, in this way, interference may occur between the blocking portion 4 and the jaw portion 3a of the manipulator 3 during the up-down sliding process, so that several requirements need to be met, namely, 1, when the jaw portion 3a is at the upper limit, enough height needs to be left between the clamping portion and the conveyor belt module 1, 2, it is necessary that the blanking is completed and after the jaw portion 3a returns to the upper limit, the blocking portion 4 is switched to the second position again.
Referring to fig. 2 and 6, alternatively, the blocking portion 4 is slidably connected to the conveyor module 1 horizontally. The first position is a limit close to the feeding position, and the second position is a limit far away from the feeding position. The direction from the second position to the first position is the same as the direction in which the workpiece 6 moves with the conveyor module 1. In this way, there is no interference between the blocking portion 4 and the jaw portion 3a of the robot arm 3. Correspondingly, after the loading is completed, the blocking part 4 needs to be directly switched to the second position. Compare "the upper and lower sliding connection of blocking part 4 in conveyer belt module 1", set up simpler and more convenient, efficiency is higher.
Referring to fig. 5, the blocking portion 4 may alternatively include a connecting portion 4a and a baffle 4b. The connection portion 4a is adapted to slide up and down with the base 2 a. The shutter 4b is fixedly attached to the connecting portion 4a and is capable of being adjusted in a fixed position of the connecting portion 4a in a direction in which the workpiece 6 moves following the conveyor belt module 1. Thus, the fixed position of the baffle plate 4b on the connecting part 4a can be adjusted, so that the position of the workpiece 6 which is blocked by the baffle plate 4b and is remained on the conveyor belt module 1 can be finely adjusted, and the workpiece 6 can be conveniently corresponding to the arranged feeding position.
