Therefore, it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the utility model, it should be noted that, unless otherwise specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The technical scheme is shown in the accompanying Figure 1 The structure is as follows: the feeding base assembly 1 connected to the centerless grinding machine through bolts, which is the connection mode between the technical scheme and the centerless grinding machine.

[0026] A linear vibrator 2 is arranged at the upper end of the feeding base assembly 1, and an automatic feeding track 3 is arranged at the upper end of the linear vibrator 2.

[0027] As shown in the accompanying Figure 2 The upper end of the automatic feeding track 3 is provided with a feeding groove 4, which is mainly in the shape of a funnel. The size requirement is that the width of the square groove at the funnel-shaped lower end of the feeding groove 4 is less than 1.5 times the diameter of the bar and greater than 1 times the diameter of the bar, so that the simultaneous conveying of two bars can be avoided.

[0028] Meanwhile, a material blocking block 11 is arranged at the front end of the automatic feeding track 3, and the material blocking block 11 is mainly arranged at the V-shaped groove at the upper end of the feeding groove 4, so that the square groove at the lower end of the feeding groove 4 can accurately feed one bar;

[0029] Two elastic members 10 are arranged at the upper end of the automatic feeding track 3, and the elastic members 10 are rubber bands, so as long as the functions of the elastic members 10 are the same, the elastic members 10 should also belong to the alternative of the technical solution, so that the bar cannot run out during the fluctuation of the subsequent driving plate 9, and the elastic force of the elastic members 10 can drive the bar into the square groove at the lower end of the feeding groove 4.

[0030] As shown in the accompanying drawings, Figure 1 A counterweight 5 is arranged at the upper end of the feeding base assembly 1, a lifting cylinder 6 is arranged on the feeding base assembly 1, a driving plate 9 is arranged at the upper end of the lifting cylinder 6 and located at the rear end of the feeding groove 4, an electromagnetic valve 7 and a time relay 8 are arranged on the feeding base assembly 1, the lifting cylinder 6 is connected with the electromagnetic valve 7 through a gas pipe, the electromagnetic valve 7 is connected with an external gas source through a gas pipe, and the electromagnetic valve 7 is connected with the time relay 8 through a wire, so as to form the condition that the lifting cylinder 6 is lifted and reset at a fixed time, and the driving plate 9 drives the end of the bar to move up and down. As known from the above, the driving plate 9 needs to move up and down at a fixed time, so as long as other driving members can meet the functions, the other driving members should also belong to the alternative of the technical solution.

[0031] Meanwhile, in order to ensure that the direction of the bar does not deviate during the vibration process, the height of the automatic feeding track 3 close to the end (front end) of the centerless grinding machine is lower than the height of the end (rear end) away from the centerless grinding machine.

[0032] The use process of the technical solution is as follows:

[0033] 1. The automatic feeding track 3 is self-made and has the same size as the bar. A plurality of bars can be placed on the automatic feeding track 3 at one time, and then the bars enter the space between the grinding wheel and the guide wheel of the machine under the vibration of the linear vibrator 2, and are ground.

[0034] 2. The electromagnetic valve 7 receives the instruction of the time relay 8, and then drives the lifting cylinder 6 through the gas pressure;

[0035] 3. The counterweight 5 is used to stabilize the automatic feeding track 3 and keep the feeding stable.

[0036] 4. The time relay 8 sends an instruction to the electromagnetic valve 7 to convert the in-out of the gas pressure, and drives the lifting cylinder 6 to move.

[0037] 5、Lift cylinder 6 receives electromagnetic valve 7 pneumatic conversion to move up and down, play the role of the rod, thus can avoid the situation of rod jam, at the same time can make the rod will be brought out of the debris in the feed groove 4, ensure the stability of the conveying process, improve the degree of automatic feeding, thus can one person look after a production line.

[0038] 6、Linear vibrator lets the feed track produce vibration force, so that the bar material slides along the feed groove 4 into the abrasive between the grinding wheel and the guide wheel.

[0039] The above, only for the preferred specific embodiments of the present application, but the scope of protection of the present application is not limited to this, any skilled in the art of the technical personnel in the technical range disclosed by the present application, according to the technical scheme of the present application and the utility model concept to replace or change, should be covered in the scope of protection of the present application.
