[0046] The specific embodiments of the present utility model will be further described in detail with reference to the accompanying drawings.

[0047] See Figures 1 to 3 As shown, the embodiment of the present application provides a grinding structure for the outer wall of a titanium alloy bar, including: a grinding platform 1, a feeding trough 7, a grinding assembly 4, and a discharging trough 8. The feeding trough 7 is arranged above the grinding platform 1, the grinding assembly 4 is arranged on the grinding platform 1, the feeding end of the grinding assembly 4 is connected to the discharging port of the feeding trough 7. The grinding assembly 4 includes a support plate 42, a synchronous pulley 43, and a grinding roller 44. The support plate 42 is located between the synchronous pulley 43 and the grinding roller 44. The synchronous pulley 43 and the grinding roller 44 are connected by a driving member 48 and a transmission member 49. The driving member 48 is driven by a first driving motor. The feeding port of the discharging trough 8 is connected to the discharging end of the grinding assembly 4. The discharging trough 8 is arranged obliquely downward from left to right.

[0048] It should be noted that the diameter size of the synchronous pulley 43 is smaller than that of the grinding roller 44, and the outer surface of the synchronous pulley 43 is provided with arc-shaped lines. By setting the driving member 48, the rotation speed of the grinding roller 44 is greater than that of the synchronous pulley 43, and the rotation directions of the grinding roller 44 and the synchronous pulley 43 are the same. During the rotation of the synchronous pulley 43, the bar to be ground 3 can be driven forward, and at the same time, the grinding roller 44 rotates to grind the bar to be ground 3.

[0049] In the above solution, by setting the support plate 42, the synchronous pulley 43, and the grinding roller 44, the bar to be ground 3 is located on the support plate 42 and between the synchronous pulley 43 and the grinding roller 44. During the processing, the bar to be ground 3 rotates on the support plate 42 between the grinding roller 44 and the synchronous pulley 43. There is no need to use a clamping assembly to clamp the bar to be ground 3. The workpiece is clamped between the grinding roller 44 and the synchronous pulley 43 and rotates in the same direction at different speeds. The grinding roller 44 rotates at a high speed to grind the bar to be ground 3, and the synchronous pulley 43 rotates in the same direction at a slower speed, thereby driving the bar to be ground 3 to rotate and move, reducing the time for clamping and loosening the bar to be ground 3, and improving the work efficiency.

[0050] In some possible implementation schemes, see Figure 2 As shown, the grinding assembly 4 further includes two slide rails 41. Each slide rail 41 is provided with a slidable support block 45. The synchronous pulley 43 and the grinding roller 44 are respectively rotatably arranged on the two support blocks 45. A bidirectional lead screw 46 is arranged through between the two slide rails 41. The two support blocks 45 are respectively sleeved on both ends of the bidirectional lead screw 46. The bidirectional lead screw 46 is driven by a second driving motor.

[0051] In the above solution, when grinding the to-be-ground bar 3 with different diameter sizes, the second drive motor is controlled to start, so that the output shaft of the second drive motor rotates to drive the bidirectional lead screw 46 to rotate. The rotation of the bidirectional lead screw 46 drives the two support blocks 45 to move relatively or towards each other in a screw manner, thereby driving the synchronous pulley 43 and the grinding roller 44 to move relatively or towards each other, and further adjusting the distance between the synchronous pulley 43 and the grinding roller 44 to adapt to the to-be-ground bar 3 with different diameter sizes.

[0052] In some possible implementation solutions, as shown in Figure 2 Figure, the driving member 48 includes a first driving wheel, a second driving wheel, a third driving wheel and a guiding wheel. The first driving wheel, the second driving wheel and the third driving wheel are respectively rotatably arranged on the support plate 42, the synchronous pulley 43 and the grinding roller 44 close to the feeding chute 7. The guiding wheel is rotatably arranged on the support plate 42 and is located above the first driving wheel. The transmission member 49 is sleeved on the first driving wheel, the second driving wheel, the third driving wheel and the guiding wheel.

[0053] In the above solution, the diameter size of the second driving wheel is larger than that of the third driving wheel, so that the rotation speed of the grinding roller 44 is greater than that of the synchronous pulley 43. At the same time, the rotation directions of the synchronous pulley 43 and the grinding roller 44 are the same.

[0054] In some possible implementation solutions, as shown in Figure 2 Figure, a vertical groove is formed on one side of the support plate 42 close to the feeding chute 7. A slidable slider is arranged in the vertical groove. The first driving wheel is arranged on one side of the slider close to the feeding chute 7. An elastic member 47 is arranged on the slider, and the upper end of the elastic member 47 is arranged at the top inside the vertical groove.

[0055] It should be noted that the elastic member 47 includes a telescopic rod and a spring sleeved on the telescopic rod, and the spring is a compression spring. The first driving wheel, the second driving wheel, the third driving wheel and the guiding wheel are sprockets, and the transmission member 49 is a chain. When adjusting the distance between the synchronous pulley 43 and the grinding roller 44, through the arranged elastic member 47, the slider can slide along the vertical groove. When adjusting the distance between the synchronous pulley 43 and the grinding roller 44, the position of the first driving wheel can change with the change of the distance between the synchronous pulley 43 and the grinding roller 44 to meet the wrap angle condition.

[0056] In some possible implementation solutions, as shown in Figure 2 Figure, water baffle plates are sleeved on both the synchronous pulley 43 and the grinding roller 44 to block the flying chips and coolant during the grinding process, avoiding the splashing of the flying chips and coolant.

[0057] In some possible implementation solutions, as shown in Figure 1As shown, an auxiliary platform 2 is arranged on the grinding platform 1 along its length direction, and a coolant nozzle 9 is arranged on the side of the auxiliary platform 2 close to the synchronous wheel 43 , and the coolant nozzle 9 is arranged toward the grinding roller 44 .

[0058] It should be noted that a circulation pump, a filter and a liquid storage tank are also provided on the auxiliary platform 2. The circulation pump draws the coolant from the liquid storage tank, filters it through the filter, and then sprays it onto the contact surface between the grinding roller 44 and the rod 3 to be ground through the coolant nozzle 9.

[0059] In some possible implementations, see Figure 1 and Figure 3 As shown, a transverse groove is opened along the length direction of the auxiliary platform 2 near the synchronous wheel 43, a push rod assembly 6 is arranged in the transverse groove, a lifting block 5 is arranged on the feeding trough 7, and part of the push rod assembly 6 is detachably connected to the lifting block 5. The push rod assembly 6 includes a screw 61 rotatably arranged in the transverse groove, the screw 61 is arranged horizontally, and a slidable connecting block 62 is also arranged in the transverse groove, the screw 61 passes through the connecting block 62, and the screw 61 is threadedly connected to the connecting block 62, a push rod 63 is hinged on the side of the connecting block 62 near the synchronous wheel 43, the push rod 63 is detachably connected to the lifting block 5, a push plate 64 is arranged on the end of the push rod 63 away from the connecting block 62, and the screw 61 is driven by a third driving motor.

[0060] It should be noted that, generally, when loading the rod 3 to be ground, the staff often manually pushes it to move it to the left side of the synchronous wheel 43 and the grinding roller 44 for grinding. This undoubtedly increases the labor intensity of the staff and also creates certain safety risks for the staff. The push rod assembly 6 is set, and the rod 3 to be ground can be automatically loaded. Specifically, by controlling the third drive motor to start, the output shaft of the third drive motor rotates, and the rotation of the output shaft of the third drive motor drives the screw 61 to rotate. The rotation of the screw 61 drives the connecting block 62 to slide in the transverse groove. The sliding of the connecting block 62 drives the push plate 64 to slide through the push rod 63, thereby pushing the rod 3 to be ground to move toward the side close to the grinding roller 44. In order not to affect the feeding during automatic loading, a lifting block 5 is set, and the upper end surface of the lifting block 5 is an inclined surface from left to right, so that when the push rod 63 moves away from the grinding roller 44, the push rod 63 gradually rotates upward along the inclined surface of the lifting block 5, thereby avoiding interference with the next rod 3 to be ground.

[0061] Through the provided support plate 42, synchronous pulley 43 and grinding roller 44, the bar 3 to be ground is located on the support plate 42 and between the synchronous pulley 43 and the grinding roller 44. During the processing, the bar 3 to be ground rotates on the support plate 42 between the grinding roller 44 and the synchronous pulley 43. There is no need to use a clamping assembly to clamp the bar 3 to be ground. The workpiece is clamped between the grinding roller 44 and the synchronous pulley 43 and rotates in the same direction at different speeds. The grinding roller 44 rotates at a high speed to grind the bar 3 to be ground, and the synchronous pulley 43 rotates in the same direction at a slower speed, thereby driving the bar 3 to be ground to rotate and move, reducing the time for clamping and releasing the bar 3 to be ground, and improving the work efficiency.

[0062] This specific embodiment is only an explanation of the utility model and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the protection scope of the utility model, they are protected by the patent law.
