Description

Technical Field

[0001] The utility model relates to bearing processing, in particular to a punching loading and unloading mechanism. Background Art

[0002] The inner and outer rings of bearings are generally processed from cylindrical blanks through heating, upsetting, punching, expanding and sizing. During the punching process, the heated and upsetting cylindrical blank needs to be placed on the punching machine, and after the punching is completed, the cylindrical blank needs to be removed from the punching machine, that is, loading and unloading. Figure 1 At present, loading and unloading are generally completed through a conveyor belt module, a blocking part and two manipulators. That is, the conveyor belt module is used to receive the cylindrical blank completed in the previous step and drive the cylindrical blank to move. The blocking part is used to block the cylindrical blank so that the cylindrical blank is stationary relative to the conveyor belt module. A manipulator is used to place the cylindrical blank from the conveyor belt module to the punching machine. The other manipulator is used to put the cylindrical blank from the punching machine back to the conveyor belt module, and the position of the return passes through the blocking part, so that the cylindrical blank can continue to move with the conveyor belt module. The existing loading and unloading mechanism still has the following problems: using two manipulators, the cost is relatively high, and the installation and adjustment requirements are also high.

[0029] See also Figure 2 and Figure 3 A punching loading and unloading mechanism includes a conveyor belt module 1, a mounting portion 2, a manipulator 3, a blocking portion 4 and a second driving mechanism 5.

[0030] The conveyor belt module 1 is a prior art, and only a section is shown in the attached figure for illustration. For the process of punching holes in the workpiece 6 in the bearing processing, the workpiece 6 is heated at high temperature before punching holes. Accordingly, 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 workpiece 6. The placed workpiece 6 moves with the upper part of the conveyor belt.

[0031] See also Figure 2 and Figure 4 The mounting portion 2 is located at the first side of the conveyor belt module 1. Accordingly, when the punching feeding and unloading mechanism is used in conjunction with a punching machine, the punching machine is located at the second side of the conveyor belt module 1 opposite to the first side. 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 by sliding up and down. The first drive 2c is used to drive the mounting platform 2b to move. Specifically, the first drive 2c can be a cylinder.

[0032] The manipulator 3 is also a prior art, and needs to have a clamping and loosening claw part 3a (used to clamp and loosen the workpiece 6), and the claw part 3a can also extend and retract in the horizontal plane (used to drive the workpiece 6 to move horizontally). The specific principles of clamping and loosening the claw part 3a and the specific principles of extension and retraction are not described in detail. The manipulator 3 is installed on the mounting platform 2b, that is, in coordination with the movement of the mounting platform 2b, the claw part 3a of the manipulator 3 can also move up and down. When the claw part 3a is at the upper limit position, it will not interfere with the workpiece 6 on the conveyor belt module 1.

[0033] After setting the specific position of the mounting portion 2, for the manipulator 3, the extension and retraction path of the jaw part 3a passes through the conveyor belt module 1, that is, the jaw part 3a needs to pass above the conveyor belt module 1. In the top view, the extension and retraction path of the jaw part 3a and the conveyor belt module 1 form an overlapping loading position. In this way, the workpiece 6 is positioned at the loading position, and the jaw part 3a of the manipulator 3 can correspond to the workpiece 6. Specifically, the jaw part 3a can correspond to the workpiece 6 in the retracted state. Through the extension and retraction on the horizontal plane and the up and down movement, the jaw part 3a can clamp the workpiece 6 and take the clamped workpiece 6 away from the conveyor belt module 1 and put it into the punching machine. Similarly, the jaw part 3a can also put the workpiece 6 that has been punched in the punching machine back to the loading position of the conveyor belt module 1.

[0034] The blocking part 4 is movably connected to the conveyor belt module 1, and the blocking part 4 switches between the first position and the second position by the movement of the blocking part 4 relative to the conveyor belt module 1. In the first position, the blocking part 4 is used to block the workpiece 6 on the conveyor belt module 1, so that the workpiece 6 remains at the loading position. In the second position, the blocking part 4 does not interfere with the workpiece 6 at the loading position and continues to move with the conveyor belt module 1.

[0035] In this way, during the loading and unloading process, the conveyor belt module 1 keeps moving. The manipulator 3 loads the material and transfers the workpiece 6 from the conveyor belt to the punching machine, and the blocking part 4 is in the first position. The manipulator 3 unloads the material and puts the punched workpiece 6 back to the loading position. After the loading or unloading is completed, the blocking part 4 switches to the second position, and the workpiece 6 returned to the loading position can continue to move with the conveyor belt module 1.

[0036] The second driving mechanism 5 is used to drive the blocking part 4 to move. The blocking part 4 needs to have two limit positions, the first position and the second position. Therefore, a cylinder can be used as the second driving mechanism 5, which is convenient to correspond to the two limit positions and is relatively simple to set.

[0037] As for the specific activity mode of the blocking part 4 in the conveyor belt module 1, the blocking part 4 can be connected to the conveyor belt module 1 by sliding up and down. The first position is the lower limit position, and the second position is the upper limit position, that is, in the second position, the workpiece 6 can pass under the blocking part 4. However, in this way, the blocking part 4 may interfere with the clamping part 3a of the manipulator 3 during the up and down sliding process, and several requirements need to be met: 1. When the clamping part 3a is in the upper limit position, it is necessary to leave enough height between it and the conveyor belt module 1; 2. The blocking part 4 must be switched to the second position after the unloading is completed and the clamping part 3a returns to the upper limit position.

[0038] See also Figure 2 and Figure 6 Optionally, the blocking part 4 is horizontally slidably connected to the conveyor belt module 1. The first position is a limit position close to the loading position, and the second position is a limit position away from the loading position. The direction from the second position to the first position is the same as the direction in which the workpiece 6 moves along the conveyor belt module 1. In this way, there will be no interference between the blocking part 4 and the clamping part 3a of the manipulator 3. Accordingly, after the loading is completed, the blocking part 4 needs to be directly switched to the second position. Compared with "the blocking part 4 is slidably connected to the conveyor belt module 1 up and down", the setting is simpler and more convenient, and the efficiency is higher.

[0039] See also Figure 5 Optionally, the blocking portion 4 includes a connecting portion 4a and a baffle 4b. The connecting portion 4a is used to slide up and down with the base 2a. The baffle 4b is fixedly connected to the connecting portion 4a, and can be adjusted to a fixed position on the connecting portion 4a along the direction in which the workpiece 6 moves along the conveyor module 1. In this way, by adjusting the fixed position of the baffle 4b on the connecting portion 4a, the position of the workpiece 6 remaining on the conveyor module 1 after being blocked by the baffle 4b can be fine-tuned, so that the workpiece 6 can be easily matched to the set loading position.
