Technical Field
[0001] The present application relates to a lock chamfering device, belonging to the technical field of workpiece processing. Background Art
[0002] Burrs usually appear on machined workpieces, which makes it inconvenient to assemble parts. Therefore, chamfers are usually made on the ends of the workpieces. An important function of chamfers is to remove burrs and make installation easier. In addition, chamfers can also reduce stress concentration and enhance the strength of parts. It can be seen that chamfers on workpieces play a very important role.
[0003] There are many lock chamfering devices on the market. One of the chamfering devices uses two cylinders to fix the two ends of the workpiece and uses a chamfering mechanism to chamfer the chamfered part of the workpiece.
[0004] However, when dealing with special locks, there may be a problem that the chamfered part of the workpiece is different from the actual chamfered part, such as Figure 1 , Figure 2 As shown, the lock 1' with a notch 2' at the bottom needs to be processed at the edge of the notch 2' of the lock 1'. Since the notch depths of different locks 1' are inconsistent during the processing of the same batch of locks 1', and the movement path of the chamfering equipment is fixed when it is working, there are certain differences in the chamfering positions of the chamfering equipment during processing.
[0005] Therefore, in order to solve the above technical problems, it is necessary to provide a lock chamfering device to overcome the above defects in the prior art. Utility Model Content

[0034] A first lock slide 1, a second lock slide 2 and a discharge trough 21 are sequentially arranged along the processing direction of the lock 1'. A sliding groove 11 is provided at the end of the first lock slide 1. The second lock slide 2 is located below the end of the first lock slide 1. The lock 1' can enter the second lock slide 2 through the sliding groove 11. The end of the second lock slide 2 is fixedly connected with the discharge trough 21. As a preferred embodiment, the cross-section of the discharge trough 21 is "V"-shaped, which is used to store the processed lock 1'.
[0035] The head end of the first lock slide 1 is slidably connected with the first sliding rod 12, and the head end of the second lock slide 2 is slidably connected with the second sliding rod 22. A pushing rod 3 is fixedly connected between the first sliding rod 12 and the second sliding rod 22. The pushing rod 3 is connected to the output end of the feeding cylinder 31. When the feeding cylinder 31 is started, it drives the first sliding rod 12 to slide along the direction of the first lock slide 1, and at the same time drives the second sliding rod 22 to slide along the direction of the second lock slide 2. The first sliding rod 12 can move the lock 1' into the sliding groove 11. The end of the first lock slide 1 is fixedly connected with a baffle 4, and the baffle 4 is slidably connected above the sliding groove 11. The baffle 4 can adjust the position of the lock 1' falling, so that the lock 1' can enter the second sliding groove 11 along the sliding groove 11, and the second sliding rod 22 can move the lock 1' into the discharge groove 21.
[0036] A first baffle plate 5 and a first stop block 6 are fixedly connected to the first lock slide 1, and a space for the lock 1' to slide back and forth is formed between the first baffle plate 5 and the first stop block 6, which is used to limit the lock 1'. A second chamfer 61 is provided on the side of the first stop block 6 close to the first sliding rod 12, and the second chamfer 61 facilitates the lock 1' to be guided between the first baffle plate 5 and the first stop block 6.

At the same time, the protrusion 811 is inserted into the notch 2' to push the lock 1' upward to make the depth of the notches 2' of different workpieces consistent, start the first pressing cylinder 9 to fix the position of the lock 1', and start the first chamfering mechanism 7 to chamfer the notch 2' of the lock 1' to ensure The chamfering positions of the same batch of workpieces are the same. The first side pressure cylinder 8 and the first top pressure cylinder 9 are removed, and the lock 1' is returned to the first lock slide 1. The lock 1' is pushed to the top of the sliding groove 11 by the first sliding rod 12. The lock 1' follows the sliding groove 11 to the second clamp 81 slide, and is pushed to between the second chamfering mechanism 27 and the second side pressure cylinder 28 by the second sliding rod 22 for back chamfering. After the chamfering is completed, the chamfered lock 1' is pushed into the discharge trough 21 by the second sliding push rod, and the discharge trough cylinder 211 is started to push the lock 1' out of the discharge trough 21.
