Description

Technical Field

[0001] The present invention relates to the field of coaxial double-sided chamfering of automotive door hinges, and more particularly, to a coaxial double-sided chamfering machine for automotive door hinges. Background Art

[0002] Due to the rapid development of the automotive industry in China in recent years, the demand for door hinge accessories has increased significantly. Most traditional enterprises still use drilling methods to process such hinges, and a large amount of manual labor is required to chamfer the orifices using a drilling machine later. This method of chamfering the orifices with a drilling machine is time-consuming and laborious.

[0003] Most existing chamfering machines fix hinge accessories between chamfering toolings through positioning toolings to achieve chamfering. The above-mentioned chamfering method has low efficiency, and manual feeding of materials to the positioning tooling is required, or feeding or conveying devices such as a vibrating disk feeding device and a stepping feeding device are set to supply materials to the positioning tooling to improve the chamfering efficiency. However, these feeding or conveying devices will occupy a large floor area.

[0004] Therefore, it is an urgent problem to be solved by the present invention to provide a coaxial double-sided chamfering machine for automotive door hinges that can improve the chamfering efficiency while reducing the floor area compared with the above-mentioned feeding or conveying devices. Summary of the Invention

[0005] In view of the above technical problems, the object of the present invention is to overcome the deficiencies in the prior art that most existing chamfering machines fix hinge accessories between chamfering toolings through positioning toolings to achieve chamfering. The above-mentioned chamfering method has low efficiency, and manual feeding of materials to the positioning tooling is required, or feeding or conveying devices such as a vibrating disk feeding device and a stepping feeding device are set to supply materials to the positioning tooling to improve the chamfering efficiency. However, these feeding or conveying devices will occupy a large floor area. Thus, a coaxial double-sided chamfering machine for automotive door hinges that can improve the chamfering efficiency while reducing the floor area compared with the above-mentioned feeding or conveying devices is provided.

[0006] To achieve the above object, the present invention provides a coaxial double-sided chamfering machine for automotive door hinges, which includes a frame, a feeding bin, a rotating disk, a driving mechanism, and a chamfering device. The feeding bin is arranged on the frame. The rotating disk is rotatably arranged at the discharge port below the feeding bin through the driving mechanism, and a plurality of assembly grooves adapted to hinge shafts are coaxially arranged around its circumference. A limiting cover is also arranged on the frame in a manner that fits around the circumference of the feeding bin. Chamfering devices are respectively arranged on opposite sides of the bottom of the rotating disk.

[0007] Preferably, the limiting cover is provided with limiting anti-detachment blocks for preventing the hinge shafts from detaching from the assembly grooves.

[0008] Preferably, a plurality of friction lines are provided on the inner side wall of the limiting cover.

[0009] Preferably, a blanking frame connected to the discharge port of the limiting cover is provided on one side of the frame.

[0010] Preferably, the inner bottom of the blanking frame is inclined.

[0011] Preferably, the driving mechanism includes a rotary driving motor, a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The second synchronous pulley is coaxially arranged on the rotating disk. The first synchronous pulley is rotatably arranged on one side of the frame through the rotary driving motor. The two opposite ends of the synchronous belt are respectively sleeved on the first synchronous pulley and the second synchronous pulley.

[0012] Preferably, a chip flushing and cooling assembly capable of flushing the chamfering position of the hinge shaft is provided on the chamfering device.

[0013] Preferably, a notch adapted to the hinge shaft is formed on the bottom of the feeding bin near the limiting cover.

[0014] Preferably, the chamfering device can chamfer the lower side of one end of the hinge shaft in the assembly groove.

[0015] According to the above technical solution, the beneficial effect of the present invention compared with the prior art is as follows: The chamfering device of the present application is specifically a chamfering grinding wheel device. The driving mechanism drives the rotating disk to rotate. The hinge shafts in the feeding bin will fall into the assembly grooves in sequence under the action of gravity, and then be brought into the limiting cover by the rotating disk. When the rotating disk continues to rotate, the circumferential side of the hinge shaft will contact the inner side wall of the limiting cover. Due to the friction between the hinge shaft and the inner side wall of the limiting cover, when the rotating disk continues to rotate, the hinge shaft will rotate under the action of friction. When the rotating disk drives the hinge shaft to rotate between the two chamfering devices, the chamfering devices will chamfer the two opposite ends of the hinge shaft, and at the same time, the hinge shaft will continue to rotate under the action of friction, so as to facilitate the chamfering devices to chamfer the two opposite ends of the hinge shaft. By combining the feeding device with the chamfering device, manual feeding is not required, and the positioning is carried out through the positioning device. Only the cooperation between the limiting cover and the rotating disk is used to position the hinge shaft. Then, while the rotating disk drives the hinge shaft to revolve, the self-rotation of the hinge shaft is realized through the friction with the inner side wall of the limiting cover, so as to cooperate with the chamfering device to chamfer the two opposite ends of the hinge shaft, improving the working efficiency and reducing the floor area at the same time.

[0027] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0028] Refer to Figure 1 and Figure 2 : An automobile door hinge coaxial two-way orifice chamfering machine, the automobile door hinge coaxial two-way orifice chamfering machine comprising: a frame 1, a feeding bin 2, a rotating disk 3, a driving mechanism 4, and a chamfering device 5. The feeding bin 2 is arranged on the frame 1. The rotating disk 3 is rotatably arranged at the discharge port below the feeding bin 2 through the driving mechanism 4, and a plurality of assembly grooves 301 adapted to the hinge shaft are coaxially arranged around its circumference. A limiting cover 101 is also arranged on the frame 1 in contact with the circumference of the feeding bin 2. Chamfering devices 5 are respectively arranged on the opposite sides at the bottom of the rotating disk 3.

[0029] The chamfering device 5 of the present application is specifically a chamfering grinding wheel device; the driving mechanism 4 drives the rotating disk 3 to rotate. The hinge shafts in the feeding bin 2 will fall into the assembly grooves 301 in sequence under the action of gravity, and then be carried into the limiting cover 101 by the rotating disk 3. When the rotating disk 3 continues to rotate, the circumferential side of the hinge shaft will contact the inner side wall of the limiting cover 101. Due to the friction between the hinge shaft and the inner side wall of the limiting cover 101, when the rotating disk 3 continues to rotate, the hinge shaft will rotate under the action of the frictional force. When the rotating disk 3 drives the hinge shaft to rotate between the two chamfering devices 5, the chamfering devices 5 will chamfer the opposite ends of the hinge shaft. At the same time, the hinge shaft will continue to rotate under the action of the frictional force, so as to facilitate the chamfering devices 5 to chamfer the opposite ends of the hinge shaft; by combining the feeding device with the chamfering device 5, manual feeding is not required, and it is fixed by the positioning device. Only the cooperation between the limiting cover 101 and the rotating disk 3 is used to position the hinge shaft. Then, while the rotating disk 3 drives the hinge shaft to revolve, the self-rotation of the hinge shaft is realized through the friction with the inner side wall of the limiting cover 101, so as to cooperate with the chamfering device 5 to chamfer the opposite ends of the hinge shaft, improving the working efficiency while reducing the floor area.

[0030] Refer to Figure 2 and Figure 4 : A limiting and anti-detaching block 10101 for preventing the hinge shaft from detaching from the assembly groove 301 is provided on the limiting cover 101.

[0031] In the present application, when the rotating disk 3 drives the hinge shaft to rotate, due to the existence of the limiting and anti-detaching block 10101, the hinge shaft will not detach from the assembly groove 301. When the rotating disk 3 drives the hinge shaft to rotate between the two chamfering devices 5, the two chamfering devices 5 will limit the hinge shaft and it will not detach from the assembly groove 301 either, so the whole device can operate normally.

[0032] Refer to Figure 2 and Figure 3 : A number of friction lines 10102 are provided on the inner side wall of the limiting cover 101.

[0033] In the present application, by providing the friction lines 10102, the friction between the hinge shaft and the inner side wall of the limiting cover 101 is increased, so as to ensure that the hinge shaft can rotate stably under the action of the rotating disk 3.

[0034] Refer to Figure 2 : A blanking rack 102 connected to the discharge port of the limiting cover 101 is provided on one side of the frame 1.

[0035] Refer to Figure 4 : The bottom inside the blanking rack 102 is inclined.

[0036] In the present application, through this design, the automatic blanking of the hinge shaft is realized, improving the blanking efficiency.

[0037] Reference Figure 5 : The driving mechanism 4 includes: a rotary drive motor 401, a first synchronous pulley 402, a second synchronous pulley 403, and a synchronous belt 404. A second synchronous pulley 403 is coaxially arranged on the rotating disk 3. One side of the frame 1 is rotatably provided with a first synchronous pulley 402 through a rotary drive motor 401. The two opposite ends of the synchronous belt 404 are respectively sleeved on the first synchronous pulley 402 and the second synchronous pulley 403.

[0038] In this application, by starting the rotary drive motor 401 to drive the first synchronous pulley 402 to rotate, the second synchronous pulley 403 is driven to rotate through the synchronous belt 404, and then the rotating disk 3 is driven to rotate.

[0039] Reference Figure 2 : The chamfering device 5 is provided with a chip flushing and cooling assembly 501 that can flush towards the chamfering position of the hinge shaft.

[0040] In this application, by providing a nozzle connected to a water source that can flush and cool towards the chamfering position of the hinge shaft, the flushing of the chips generated by chamfering is realized, and at the same time, the chamfering device 5 is cooled.

[0041] Reference Figure 3 : A notch 201 adapted to the hinge shaft is opened at the bottom of the feeding bin 2 near one side of the limit cover 101.

[0042] In this application, through this design, it is convenient for the hinge shaft to enter the limit cover 101 through the notch 201.

[0043] Reference Figure 2 : The chamfering device 5 can chamfer the lower side of one end of the hinge shaft in the assembly groove 301.

[0044] In this application, through this arrangement, chamfering of the opposite ends of the hinge shaft is realized during the rotation of the hinge shaft.

[0045] When the device provided by the present invention is in use, the driving mechanism 4 drives the rotating disk 3 to rotate. The hinge shafts in the feeding bin 2 will fall into the assembly grooves 301 in sequence under the action of gravity, and then are carried into the limiting cover 101 by the rotating disk 3. When the rotating disk 3 continues to rotate, the circumferential side of the hinge shaft will contact the inner side wall of the limiting cover 101. Due to the friction between the hinge shaft and the inner side wall of the limiting cover 101, when the rotating disk 3 continues to rotate, the hinge shaft will rotate under the action of the frictional force. When the rotating disk 3 drives the hinge shaft to rotate between the two chamfering devices 5, the chamfering devices 5 will chamfer the opposite ends of the hinge shaft. At the same time, the hinge shaft will continue to rotate under the action of the frictional force, so that the chamfering devices 5 can chamfer the opposite ends of the hinge shaft; by combining the feeding device with the chamfering devices 5, manual feeding is not required, and it is fixed by the positioning device. The hinge shaft is positioned only by the cooperation of the limiting cover 101 and the rotating disk 3. Then, while the rotating disk 3 drives the hinge shaft to revolve, the rotation of the hinge shaft is realized by the friction between the hinge shaft and the inner side wall of the limiting cover 101, so as to cooperate with the chamfering devices 5 to chamfer the opposite ends of the hinge shaft, improving the work efficiency and reducing the floor area at the same time.

However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0047] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable way without contradiction. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0048] In addition, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, it should also be regarded as the content disclosed by the present invention.
