[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figures 1 - 3 , an embodiment provided by the present invention: A thread rolling machine for screw processing, including a machine body 1, a processing table 2 is fixedly connected to the surface of the top of the machine body 1, a thread rolling device 4 is arranged on the surface of the processing table 2, and the thread rolling device 4 is a prior art. By moving the thread rolling device 4 up and down on the surface of the processing table 2, screws can be thread rolled. A feeding port 3 is fixedly connected to the top of the outer wall of the machine body 1. Through the feeding port 3, screws can be replenished on the surface of the processing table 2, which is a prior art. A valve 5 is fixedly connected to the outer side wall of the machine body 1. A cavity is provided in the inner side wall of the machine body 1, so that the processing oil after being filtered by the up-and-down swinging of the blanking plate 61 will flow into the cavity of the inner side wall of the machine body 1, and thus the filtered processing oil inside can be reused through the valve 5.

[0032] Referring to Figures 2 - 3 , a vibration assembly 6 is arranged on the inner surface of the machine body 1. The vibration assembly 6 includes a blanking plate 61. The outer wall on the right side of the blanking plate 61 is slidably connected to the inner side wall of the processing table 2. A chute that fits both sides of the blanking plate 61 is provided in the left inner wall of the processing table 2, so that the blanking plate 61 can only move up and down on the inner wall of the processing table 2. The outer wall on the left side of the blanking plate 61 is slidably connected to the inner side wall of the machine body 1. A guide groove that fits the outer wall on the left side of the blanking plate 61 is also provided in the left inner wall of the machine body 1, so as to prevent the left side from getting stuck when the right side of the blanking plate 61 is squeezed and raised. The blanking plate 61 is elastically connected to the inner wall of the processing table 2 through a limiting spring 62. One end of the limiting spring 62 is fixedly connected to the bottom end of the outer wall on the right side of the blanking plate 61, and the other end of the limiting spring 62 is fixedly connected to the bottom end of the inner wall of the processing table 2. The function of the limiting spring 62 is to automatically reset the position of the blanking plate 61 after being squeezed and moved.

[0033] Referring to Figures 2 - 3Two groups of fixed blocks 63 are fixedly connected to the surface on the inner side of the body 1, and the outer wall of the fixed block 63 is fixedly connected to the motor 64. An elliptical block 65 is rotatably connected between the two groups of fixed blocks 63. The output shaft of the motor 64 is fixedly connected to the rotation center axis of the elliptical block 65. The outer wall of the elliptical block 65 contacts the bottom end of the outer wall of the blanking plate 61, and contacts the bottom end of the blanking plate 61 through the rotation of the elliptical block 65, so that the blanking plate 61 cooperates with the limit spring 62 to achieve the effect of up and down vibration, avoiding the adhesion between the screws and the processing oil and adsorption on the surface of the blanking plate 61. The outer wall of the bottom end of the blanking plate 61 is provided with a collecting component 7.

[0034] Reference Figure 2 and Figure 4 The collecting assembly 7 includes a hinged rod 71, and the bottom end of the outer wall of the hinged rod 71 is hinged with a collecting box 72. The top of the outer surface of the collecting box 72 is slidably connected to the inner wall of the bottom end of the machine body 1. A sliding groove is provided at the top of the inner wall of the machine body 1, so that the top of the collecting box 72 can only move forward and backward on the inner wall of the bottom end of the machine body 1 and cannot be separated from its inner wall. The end of the hinged rod 71 away from the collecting box 72 is hinged to the outer wall of the bottom end of the blanking plate 61. When the blanking plate 61 rises, the hinged rod 71 hinged to the outer wall of its bottom end will drive the collecting box 72 to move forward and backward. The inner wall of the machine body 1 moves back and forth laterally, so that the bolts after processing swing back and forth to avoid accumulation on one side of the surface of the collecting plate 75. The inner wall of the collecting box 72 is slidably connected to the collecting plate 75. The collecting plate 75 is provided with a cavity inside. The screws after processing can be collected and placed through the cavity, and the surface is provided with a filter hole to filter the debris after the screw processing to separate the screw from the debris. The inner wall of the collecting box 72 is elastically connected to the wedge block 74 through the reset spring 73.

[0035] Reference Figure 4 The wedge block 74 is slidably connected to the inner wall of the collection box 72, and a slot is provided at the bottom end of the outer wall of the collection plate 75. The top of the outer wall of the wedge block 74 is engaged with the inner wall of the slot. The engagement between the two fixes the position of the collection plate 75 on the inner wall of the collection box 72 to prevent the collection plate 75 from detaching from the inner wall of the collection box 72 during use. One end of the return spring 73 is fixedly connected to the bottom end of the outer wall of the wedge block 74, and the other end of the return spring 73 is fixedly connected to the bottom end of the inner side wall of the collection box 72. The function of the return spring 73 is to automatically reset the position of the wedge block 74 after being squeezed and moved. The outer wall of the bottom end of the collection box 72 is hinged with a baffle 76.

[0036] Working principle: When the screws fall from the feeding port 3 onto the surface of the processing table 2, they will be thread-rolled by the movement of the thread-rolling device 4. After the processing is completed, the screws will fall onto the surface of the blanking plate 61. At this time, the motor 64 can be started to drive the output shaft to drive the elliptical block 65 to rotate. Thus, when the elliptical block 65 rotates, it will squeeze the blanking plate 61 to move upward on the inner wall of the processing table 2, and the limiting spring 62 will be elastically stretched. Until the elliptical block 65 cancels the contact with the bottom end of the blanking plate 61, the blanking plate 61 will be restored to its initial position under the elastic action of the limiting spring 62, so that the blanking plate 61 can achieve the effect of reciprocating up and down swinging, avoiding the adhesion between the screws and the processing oil from adsorbing on the surface of the blanking plate 61. And the processing oil filtered by the blanking plate 61 will fall into the cavity on the inner side wall of the machine body 1, and can be connected to the valve 5 through an external pipeline, so that the processing oil can be recycled.

[0037] At the same time, during the up-and-down swinging process of the blanking plate 61, the collecting box 72 will be driven by the hinge rod 71 to move horizontally on the inner wall at the bottom of the machine body 1, so that the collecting box 72 drives the collecting plate 75 to swing reciprocally, so as to shake the screws collected by the collecting plate 75, avoiding the screws from piling up on one side of the collecting plate 75 and requiring manual leveling. At the same time, during the reciprocating shaking process of the collecting box 72, the debris in the screws falling on the surface of the collecting plate 75 will fall through the filter holes of the collecting plate 75 to the bottom end of the inner wall of the collecting box 72, thus avoiding the debris and the screws from piling up together and requiring manual selection in the follow-up. And by moving the wedge block 74 downward to disengage from the clamping of the bottom slot of the collecting plate 75, the collecting plate 75 can be taken out from the inside of the collecting box 72 as a whole to centrally process the screws processed on its surface.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
