Technical Field

[0001] The utility model belongs to the field of metal component processing, and particularly relates to a grinding machine for small metal components. Background Art

[0002] With the rapid progress of technology, metal components, as the basic elements of mechanical manufacturing, are widely used in fields such as aerospace, automobile manufacturing, and precision machinery. The processing precision, surface quality, and production efficiency of metal components directly affect the performance and market competitiveness of the final products.

[0003] After the production of metal components is completed, the metal components are inspected one by one, and those with a little burr on the surface are removed. Then, a grinding machine is used to polish the surface to remove the burrs. However, before grinding, the existing grinding machine needs to send the metal components to the processing table and position them, which is laborious and time-consuming, and the efficiency is also low. In addition, the existing processing table cannot adapt to metal components of different specifications and sizes. Content of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide a grinding machine for small metal components, aiming to solve the problems that the existing grinding machine for small metal components is laborious and time-consuming in the grinding process, has low efficiency, and cannot adapt to metal components of different specifications and sizes.

[0014] In order to make the patent purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0016] For the sake of convenience of illustration, only parts related to the embodiments of the present utility model are shown.

[0017] Combined with Figures 1 - 3 As shown, the grinding machine includes a machine table 1, a processing table 2 is provided on the machine table 1, belt feeding tables are respectively provided at both ends of the processing table 2, a grinding wheel assembly and an adjusting wheel assembly are respectively provided on both sides of the processing table 2. The processing table 2 includes a base 21 installed on the machine table 1, a material receiving plate 23 is provided on the base 21, fixing seats 24 are provided at both ends of the base 21, a pair of adjusting arms 25 are rotatably provided in the fixing seats 24, guide plates 26 are provided on the inner sides of each adjusting arm 25, short columns 22 are provided at the bottoms of the adjusting arms 25, a tension spring 27 is provided between the same pair of short columns 22, and an adjusting component for adjusting the opening angle of the same pair of adjusting arms is further provided on the processing table 2.

[0018] In this embodiment, the belt feeding table at the right end of the processing table 2 is the loading belt feeding table 31, and the belt feeding table at the left end is the unloading belt feeding table 32. And there is a loading mechanism 12 at the right end of the loading belt feeding table 31. When using this grinding machine to process small metal components, it is necessary to place the small metal components to be processed on the loading mechanism according to requirements before that. The loading mechanism loads the small metal components onto the loading belt feeding table one by one and in an orderly manner. The loading belt feeding table slowly conveys the small metal components towards the processing table. When the small metal component is conveyed to the processing position, the grinding wheel assembly and the adjusting wheel assembly perform grinding processing on it. The small metal components mentioned in the text are of a cylindrical structure.

[0019] Since this grinding machine is a centerless grinding machine, as Figure 1 , both the grinding wheel assembly and the adjusting wheel assembly are installed on the moving module 5. The grinding wheel assembly mainly consists of a grinding wheel 31 and a grinding motor 32 for driving the rotation of the grinding wheel. The adjusting wheel assembly mainly consists of an adjusting wheel 41 and an adjusting motor 42 for driving the rotation of the adjusting wheel. And the moving module and the loading mechanism are not the key contents of this device, so they will not be specifically described here.

[0020] When the small metal component is conveyed to the processing position, both the grinding wheel assembly and the adjusting wheel assembly move one station towards the processing table under the drive of the moving module and come into contact with the current small metal component respectively. The grinding wheel and the adjusting wheel rotate simultaneously. At this time, the grinding wheel rotates at a high speed to grind the current small metal component. At the same time, the adjusting wheel rotates in the same direction at a slower speed, thereby driving the current small metal component to rotate and perform circular feeding. After the current small metal component is processed, both the grinding wheel assembly and the adjusting wheel assembly retreat one station backward. The current small metal component is pushed out of the processing position by the next small metal component. At this time, the next small metal component is located at the processing position and waits to be processed.

[0021] In actual situations, the current small metal is still on the processing table. When the next small metal component is processed and completed, it is pushed out of the processing position by the subsequent small metal components. At this time, the current small metal is pushed onto the unloading belt feeding table for unloading. In this way, the small metal component grinding machine can process all small metal components orderly and one by one, and the processing efficiency is relatively high.

[0022] The processing table includes a base. There is a material bearing plate on the top surface of the base. A pair of adjusting arms are rotatably provided at both ends through fixed seats. There are guide plates on the adjusting arms. In actual situations, the area between the two pairs of guide plates on the material bearing plate is the processing position. The grinding wheel and the adjusting wheel are arranged towards the processing position.

[0023] As a preferred structure, as Figures 2 - 3, a notch 6 is formed in the middle of the adjusting arm 25. The adjusting assembly includes a V-shaped limiting block 7 rotatably installed in the fixed seat, and both ends of the V-shaped limiting block 7 penetrate through the notch 6 on the same side. An adjusting screw 8 is also screwed into the top of the adjusting arm 25, and the bottom of the adjusting screw 8 abuts against the corresponding position of the V-shaped limiting block 7.

[0024] When processing small metal components located at the processing position, the material supporting plate plays a supporting role, and a V-shaped material supporting groove is formed in the material supporting plate. The material supporting groove is designed in a V-shaped structure, which can facilitate the feeding of small metal components and improve the stability of small metal components during the processing. In addition, during the entire processing and feeding process, the two pairs of guide plates play a guiding and limiting role.

[0025] During the processing, the opening angle of the same pair of adjusting arms can be finely adjusted to adapt to small metal components with different diameters, thereby improving the adaptability of the device. When using this grinding machine to process small metal components with a larger diameter, in order to adapt to the size of the small metal components, the processing table needs to slightly increase the opening angle of the same pair of adjusting arms. Specifically: only need to loosen all the adjusting screws, and the number of turns of all the adjusting screws is the same. At this time, all the adjusting screws move upward a small distance, and the adjusting screws are away from the V-shaped limiting block by a small distance. Under the action of the tension spring, the two adjusting arms of the same pair rotate outward until the adjusting screws re-abut against the corresponding positions of the V-shaped limiting block on the same side. At this time, the adjustment of the adjusting arm is completed. And when the adjusting arm rotates, the V-shaped limiting block plays a guiding role for it, making the adjusting arm more stable during rotation.

[0026] Further, as a preferred structure, as Figure 2 , V-shaped grooves 9 are formed in the upper and lower positions of the guide plate 26 along the length direction. A matching clamping groove 10 is formed in the inner side and the bottom of the adjusting arm 25 corresponding to the V-shaped groove 9. After the lower part of the guide plate 26 is clamped into the clamping groove, it is locked by a locking block 11.

[0027] In this structure, the guide plate is of a detachable design structure, and the adjusting screw passes through the corresponding locking block and is screwed into the adjusting arm. The bottom of the adjusting screw abuts against the V-shaped limiting block. When the guide plate needs to be removed, just remove the locking block first. After the locking block is removed, the guide plate can be removed. From the structure, the installation structure of the guide plate is relatively simple. And the two guide plates of the same pair are both inclined downward and inward, which can make the guiding and limiting effects on small metal components better.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the present utility model.
