Embodiment 1

[0029] see figure 1 and figure 2, the chain feeding mechanism of the chain grinding machine provided in this embodiment is used to send the saw chain to the grinding position, which includes a chain feeding support frame 1 driven by a driving device (such as a motor) for translational movement and a chain supporting frame 1 with the chain feeding mechanism. One end of the frame 1 is pivotally connected to the chain feeder 2, and the direction in which the chain feeder 2 pushes the chain is parallel to the moving direction of the saw chain. In this embodiment, the chain feeder 2 is in the shape of a rod, but it can also be in the shape of a sheet Or any other suitable shape; the chain feeder 2 includes a chain feeder 21 that pushes the chain feeder and a connecting portion 22 that is integrally formed with the chain feeder 21, and the connecting portion 22 and the chain feeder 21 are bent. , and the bending angle ensures that the height of the connecting portion 22 and the co...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that this embodiment provides another connection structure between the chain feeding support frame and the driving device. For details, see Figure 4 , the chain feeding support frame 1 is integrally formed on a screw nut 10, and the screw nut 10 is sleeved on a screw rod 12, and the screw rod 12 is driven to rotate by a driving device 9. Specifically, the driving device 9 can be a motor. The driving device 9 drives the screw rod 12 to rotate to make the screw nut 10 translate, and then drives the chain feeding support frame 1 to translate to feed the chain. In addition, the chain feeding support frame 1 and the screw nut 10 can also be fixedly connected.

[0038] The above-mentioned structure of this embodiment can also realize the function of moving the chain-feeding support frame in translation, but its distance control accuracy is not as high as that of Embodiment 1.

Abstract

The invention discloses a chain feeding mechanism of a chain grinding machine, which is used for feeding a saw chain to a grinding position. The chain feeding mechanism comprises a chain feeding support frame driven to perform the translational motion by a driving device, and a chain feeding piece in pivoted connection with one end of the chain feeding support frame, wherein the direction of the chain feeding piece pushing and feeding the chain is parallel to the moving direction of the saw chain; the chain feeding piece has a bottom surface capable of pressing at the upper ends of limiting teeth of a blade of the saw chain, and a front end surface capable of pushing the blade of the saw chain to move; and the front end surface is arched. The chain feeding mechanism solves the problem of easy turning of the saw chain in the automatic chain feeding process from front to back, is high in control precision of the chain feeding distance, and guarantees the grinding precision.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a chain feeding mechanism of a chain grinding machine. Background technique [0002] Chinese patent application "201310423659.3" discloses a fully automatic saw chain grinding machine and a saw chain grinding method using the grinding machine, innovatively using the saw chain blade edge as a reference from front to back to feed the chain The method solves the problem that the traditional back-to-front chain feeding method easily causes the blade to be over-grinded or not ground due to the tolerance of the length of the cutting teeth. However, when the chain feeding mode was changed from front to back, a new problem occurred: since the chain feeding push position of the chain feeding mode from front to back is located in the groove at the front end of the blade edge of the saw chain, it is different from that from rear to back. The pushing position of the forward feed chai...
