Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0025] Embodiment 1
[0026] Please refer to Figures 1-3 The embodiment provides the following technical scheme: a machine tool bearing steel ball finished product screening machine, which comprises a sieve plate 1, coamings 2 are fixedly connected to the front and rear sides of the sieve plate 1, a flow channel region and a planar region are arranged between the front and rear coamings 2 on the sieve plate 1, in some embodiments, the flow channel region is arranged at the feeding end of the sieve plate 1, and the planar region is arranged at the discharging end of the sieve plate 1.
[0027] Intercepting baffles 3 fixedly connected with the coamings 2 are arranged on the left and right sides above the flow channel region, in some embodiments, the intercepting baffles 3 are suspended above the sieve plate 1, and the intercepting baffles 3 and the sieve plate 1 jointly form a steel ball flow-through cavity, the setting of the intercepting baffles 3 avoids the stacking of the steel balls entering the sieve plate 1, thereby affecting the screening work of the steel balls.
[0028] A plurality of flow channel grooves 4 distributed at intervals are further arranged between the intercepting baffles 3 on the left and right sides in the flow channel region, in some embodiments, the flow channel grooves 4 are of a conical structure, the setting of the flow channel grooves 4 can guide the steel balls entering the flow channel and make the originally disordered steel balls orderly, thereby improving the screening effect of the steel balls.
[0029] A ball detection groove 5 penetrating through the sieve plate 1 is arranged on the flow channel groove 4, the setting of the ball detection groove 5 can make the small balls smaller than the width of the ball detection groove 5 discharged from the flow channel groove 4 in the rolling process of the steel balls in the flow channel groove 4.
[0030] The upper side of the planar area is also provided with a ball clamping plate 6, which cooperates with the adjacent intercepting baffle 3 to form a ball temporary storage cavity. The bottom of the ball clamping plate 6 is provided with a plurality of spaced ball clamping grooves 7. By arranging the ball clamping plate 6 on the discharge end of the sieve plate 1, the traditional front ball clamping mode is changed, thereby avoiding the diffraction ball blocking phenomenon and avoiding the large-diameter balls clamped on the feed end of the sieve plate 1, which requires shutdown to remove the large-diameter balls, thereby improving the operation efficiency of the balls. The ball clamping grooves 7 can make the qualified balls discharged from the sieve plate 1 along the ball clamping grooves 7, and the unqualified balls are temporarily stored in the ball temporary storage cavity.
[0031] In some embodiments, the diffraction ball blocking phenomenon is the bending and diffusion phenomenon of the balls when encountering obstacles or passing through slits.
[0032] In some embodiments, a chamfer 8 is arranged on the side wall of the ball clamping groove 7.
[0033] In some embodiments, during use, the oil-coated balls are conveyed through the conveying belt, so that the balls enter the sieve plate 1 through a plurality of spaced flow channel grooves 4.

The blocking plate 902 is vertically and slidably connected in the discharge chute 901, which is used to make the discharge chute 901 in a closed or open state. By arranging the discharge chute 901 and the blocking plate 902, the balls flowing in the flow channel grooves 4 can move towards the ball clamping grooves 7 through the blocking plate 902 when the discharge chute 901 is in a closed state, and the large-diameter balls clamped in the ball temporary storage cavity can be discharged when the discharge chute 901 is in an open state, thereby replacing the manual removal of the large-diameter balls in the ball temporary storage cavity.
[0036] The front and rear sides of the blocking plate 902 are fixedly connected with lifting plates 903, and the other ends of the lifting plates 903 extend out of the discharge chute 901 and are fixedly connected with extension plates 904.
