Fig. 1a shows an alternative embodiment of the roller chamfering machine of the present invention.

In this alternative embodiment, the roller chamfering machine includes: transmission line 100, grater assembly 200, clamping assembly 300 and movement assembly 400.

Wherein, the transmission line 100 drives the roller bar 1 to move along the axial direction of the roller bar, the number of the transmission lines 100 is two, and the transmission directions of the two transmission lines are opposite (the transmission directions are shown by arrows in fig. 1 a). The transmission line 100 is used for driving the roller bar 1 to move along the axial direction of the roller bar, and the roller bar to be processed which is transmitted to the transmission line is transmitted to the grinding head assembly 200.

And two grinding head assemblies 200, each grinding head assembly 200 corresponding to one transmission line 100, the grinding head assemblies 200 being disposed at the ends of the transmission line 100 in the conveying direction. The grinding head assembly 200 is used for grinding the edge of the roll bar to be processed, and the grinding head assembly 200 can be implemented by adopting the existing technical scheme, for example, the driving motor drives the grinding wheel to grind the edge of the roll bar.

The clamping assembly 300 is arranged in front of the grinding head assembly 200, and the clamping assembly 300 clamps the roller rod 1 and drags the roller rod 1 to move axially along the roller rod. The 1 speed of the roller stick of conveying on the transmission line is unstable, and the precision of transmission line transfer rate also can't satisfy the requirement moreover, and centre gripping subassembly 300 carries out the centre gripping to the roller stick, and the roller stick is by the centre gripping back, and centre gripping subassembly 300 can accurate drive roller stick displacement, and then improves the precision of chamfer process. Of course, after the end of the roller bar 1 to be machined is machined, the clamping assembly 300 also drags the roller bar 1 to move in the direction away from the grinding head assembly 200, so that the roller bar 1 is separated from the grinding head assembly 200.

The position sensor (not shown in fig. 1 a) is used for detecting the edge position of one end of the roller bar 1 to be processed, outputting a position signal, and the clamping assembly 300 drags the roller bar 1 to move towards the grinding head assembly 200 by a set feeding distance according to the position signal. The position sensor is arranged in front of the grinding head assembly, the clamping assembly clamps the roller and drives the roller to move axially, the edge of the roller 1 reaches the position sensor, the position sensor outputs a position signal, the clamping assembly 300 drives the roller to move towards the grinding head assembly 200 according to the position signal, the moving distance can be accurately controlled, and then the accurate chamfering of one end to be machined of the roller is achieved. For example, the chamfering amount of the roller (the chamfering amount is the feeding amount of the roller in the grinding head of the grinding head assembly) can be calculated according to the chamfering model, the distance between the position sensor and the grinding head assembly is fixed, and therefore, according to the position signal output by the position sensor, the clamping assembly 300 drags the roller 1 to move towards the grinding head assembly 200 for the set feeding distance, and accurate chamfering of the roller is realized. The above process of setting the feed distance of the gripping assembly based on the edge position signal of the roll bar and the feed amount does not involve the modification of the existing control program, which is implemented by using the existing known program. Alternatively, the clamping assembly 300 clamps the roller bar 1, and pulls the roller bar 1 to move towards the direction close to the grinding head assembly 200, and the edge of the end to be processed of the roller bar 1 reaches the position sensor. With the above alternative embodiment, in the case that the edge of the end to be processed of the roller bar 1 is farther from the grinding head assembly 200 than the position sensor after the clamping assembly 300 clamps the roller bar 1, the clamping assembly 300 needs to drag the roller bar 1 to move towards the direction close to the grinding head assembly 200, so that the edge of the end to be processed of the roller bar 1 is detected by the position sensor. Optionally, the clamping assembly 300 clamps the roller bar 1, and drags the roller bar 1 to move in the direction away from the grinding head assembly 200, and the edge of the end to be machined of the roller bar 1 reaches the position sensor. With the above alternative embodiment, in the case that the edge of the end to be processed of the roller stick 1 is closer to the grinding head assembly 200 than the position sensor after the clamping assembly 300 clamps the roller stick 1, the clamping assembly 300 needs to drag the roller stick 1 to move in the direction away from the grinding head assembly 200, so that the edge of the end to be processed of the roller stick 1 is detected by the position sensor. Of course, those skilled in the art may also adopt other technical solutions to achieve the purpose of detecting the edge of the to-be-processed end of the roller, for example, making a mark on the roller, detecting the mark, or detecting the edge of the other end of the roller, which is all for achieving the purpose of detecting the edge of the to-be-processed end of the roller. Alternatively, the position sensor may be a distance measuring sensor, a photoelectric correlation switch, or another sensor that can be used to determine the position of the target object.

And the moving assembly 400 is used for driving the roller bar 1 to move horizontally, and the direction of the horizontal movement is perpendicular to the axial direction of the roller bar. The moving assembly 400 is used for driving the roller rods to move among the feeding port, the two transmission lines and the discharging port, transmitting the roller rods to be processed to the first transmission line from the feeding port, transmitting the roller rods with the processed ends to the second transmission line from the first transmission line, and transmitting the roller rods with the processed ends to the discharging port from the second transmission line.

Optionally, the baffle 500 is further provided with a sensor, and when the sensor senses that the baffle 500 is impacted, the sensor outputs a control signal to control the corresponding transmission line to stop operating.
