Description

Technical Field

[0001] The utility model relates to the technical field of chamfering machines, in particular to a track pin chamfering machine. Background Art

[0002] Track pins are one of the important parts of crawler machinery (such as excavators, loaders, etc.), and their chamfering has an important impact on the normal operation and service life of the equipment. Chamfering can increase the contact area between the track pin and the crawler, improve wear resistance and anti-wear performance, and also help reduce friction noise and energy consumption.

[0003] Track pin chamfering machines usually use rotary tools or stamping dies to perform chamfering. In the rotary tool method, the tool rotates to cut the edge of the track pin into the required chamfer shape; in the stamping die method, the die presses the edge of the track pin into the required chamfer shape through stamping.

[0004] For example, the patent (CN214517965U) discloses a pin chamfering device, which records that "it realizes the function of automatically sorting and feeding the pins, and the push rack and the processing table cooperate to quickly fix the pins, solving the problem of manual material discharge and clamping during processing" and also records that "the traditional chamfering machine requires manual material discharge and clamping during the chamfering process, and can only chamfer one end of the pin, which is very inconvenient to use."

[0005] When using the above technology, it was found that the following technical problems exist in the prior art: the above device can only process a single pin shaft at a time, but cannot ensure that only a single pin shaft falls on the telescopic slide. This can easily lead to multiple pin shafts being located on the telescopic slide at the same time during processing, which in turn leads to processing problems and damage to the equipment. For this reason, we designed a track pin chamfering machine to provide another technical solution to the above technical problems. Utility Model Content

[0032] Embodiment 2

[0033] Reference Figure 6, Track pin chamfering machine, the second clamping block 8 is fixed with anti-detachment hook strips 25 at both ends of the lower end of one side close to the first clamping block 7, and the first clamping block 7 is provided with a connecting groove at a position corresponding to the anti-detachment hook strip 25, and the anti-detachment hook strip 25 is plug-connected with the first clamping block 7 through the connecting groove;

[0034] The device provided in this embodiment can limit the position of the pin when it falls through the structural design of the anti-drop hook strip 25, so as to prevent the pin from falling off from the inner side of the second clamping block 8.

[0035] The use process of the track pin chamfering machine provided by the utility model is as follows: when in use, first place the pin shaft inside the placement cavity 12 opened inside the placement box 5, and then start the hydraulic rod 11, so that the hydraulic rod 11 drives the second clamping block 8 to move in the direction close to the placement box 5 through the connecting plate 10 and the fixed block 9. When the fixed block 9 moves, it squeezes the moving plate 13, so that the moving plate 13 drives the sliding block 14 to move at the same time and compresses the sliding rod 15 through the sliding block 14. When the moving plate 13 moves, it drives the moving frame 17 and the first baffle 19 to move simultaneously. When the first baffle plate 19 moves to be separated from the placement cavity 12, the placement cavity 12 is close to the gap away from the moving plate 13, and only a single pin can be discharged, so that the single pin located inside the placement cavity 12 will fall from the inside of the placement cavity 12 to the top of the anti-detachment hook strip 25. At the same time, when the moving frame 17 moves, the first rack 18 fixed thereto drives the transmission gear 20 meshing with the first rack 18 to rotate at the same time. When the transmission gear 20 rotates, the second rack 24 meshing therewith drives the moving block 22 and the second baffle plate 23 to approach. The first clamping block 7 moves in the direction of the first clamping block 7, so that when the second baffle plate 23 moves to the inside of the placement cavity 12, it will limit the other pins above it to prevent other pins from falling at the same time. Then, by starting the hydraulic rod 11 in the reverse direction, the pin placed on the top of the anti-drop hook strip 25 moves under the push of the second clamping block 8. When the second clamping block 8 and the fixed block 9 move to no longer contact the fixed block 9, the sliding block 14 is pushed in the direction close to the second clamping block 8 under the elastic action of the sliding rod 15, so that the moving plate 13 is driven to move by the sliding block 14. , and then the first baffle 19 moves to the inside of the placement cavity 12, and the second baffle 23 moves to the inside of the placement box 5 and disengages from the placement cavity 12, so that the next pin to be processed falls to the top of the first baffle 19, and at the same time, the pin located at the top of the anti-detachment hook strip 25 is clamped by the second clamping block 8 and the first clamping block 7, and then the grinding mechanism 3 is started to chamfer the clamped pin. After the processing is completed, the hydraulic rod 11 is started to move the second clamping block 8, thereby canceling the limit on the pin, and the pin can be removed to complete the operation.
