Description

TECHNICAL FIELD

[0001] The utility model mainly relates to metal polishing technical field, concretely relates to a metal medical instrument manufacturing surface polishing device. BACKGROUND

[0002] In the field of metal medical instrument manufacturing, surface polishing is a very critical link, directly related to the performance, safety and service life of the instrument. However, the traditional metal medical instrument surface polishing method has many drawbacks.

[0003] From the artificial operation level, the previous many rely on artificial hand-held polishing tool to polish the instrument. This way not only the labor intensity is extremely great, and the polishing efficiency is low, and due to the difference of artificial operation, it is difficult to ensure that the polishing quality of each medical instrument is completely consistent. For example, when polishing small precision metal medical instruments, it is difficult for artificial to accurately control the polishing force and angle, and it is easy to appear overpolishing or underpolishing, resulting in high product scrap rate.

[0004] In terms of equipment, the traditional polishing equipment is usually simple in structure and single in function. The material moving and feeding link often lacks automatic design, and the medical instrument to be polished needs to be placed in the polishing position manually, which not only easily causes position deviation and affects polishing accuracy, but also greatly limits production efficiency. Moreover, the polishing mechanism of the traditional polishing equipment cannot flexibly adjust the polishing parameters, and it is difficult to adapt to the diversified polishing needs of metal medical instruments of different materials, shapes and sizes.

[0005] In addition, in the traditional polishing process, the collection of polished instruments is also relatively arbitrary, which easily causes secondary damage to the surface of the instrument and affects the product quality. With the continuous development of the medical instrument industry, higher requirements are put forward for the quality and production efficiency of metal medical instruments, and it is urgent to develop a high-efficiency, accurate and highly automated metal medical instrument manufacturing surface polishing device.

[0014] 3. Advantageous effects:

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The various mechanisms of the whole device work cooperatively, from material moving, feeding, clamping to polishing, and each link can ensure the position accuracy and stability of the medical instrument. This helps to ensure the uniformity and consistency of polishing, reduces the polishing defects caused by position deviation or instability, thereby improving the surface quality of the metal medical instrument, and meeting the strict requirements of medical instruments for high-quality surface treatment.

[0017] The material moving mechanism of the utility model realizes the automatic material moving process from the feeding box to the feeding mechanism through the cooperation of the linear module, the electric push rod and the clamping jaw. This process reduces manual operation, improves the accuracy and efficiency of material moving, avoids material damage or position deviation caused by manual operation, and ensures the continuity of polishing work. For example, when batch producing metal medical devices, the devices to be polished can be quickly and stably moved to the feeding position one by one, greatly improving the production efficiency.

[0018] The chain wheel and chain transmission mode of the feeding mechanism of the utility model, in cooperation with the design of the placing block and the storage groove, can stably deliver the medical devices to the designated position. The motor two can accurately control the rotating speed and angle of the chain wheel, thereby ensuring the accuracy and stability of feeding. This stable feeding mode helps to improve the quality of the subsequent polishing process, because only when the position of the medical device is stable, the polishing can be uniformly and accurately carried out.

[0019] The structure of the driving wheel, the driven wheel and the polishing belt of the polishing mechanism of the utility model, and the mode that the motor one drives the driving wheel through the belt pulley assembly, enable the polishing belt to stably rotate. The rotating polishing belt can quickly and effectively remove impurities on the surface of the medical device, improving the polishing efficiency. At the same time, by adjusting the rotating speed of the motor one, medical devices of different materials and polishing requirements can be adapted, improving the versatility of the polishing device.

[0037] The linear module 61 is started, and according to the set program, the output end drives the mounting block 62 to move to the designated position above the feeding box 4. Then, the electric push rod 63 is extended, and the connecting plate 64 and the clamping jaw 65 are driven to move downward. When the clamping jaw 65 reaches the appropriate position, the clamping jaw 65 clamps a medical device 9 in the feeding box 4. Subsequently, the electric push rod 63 is retracted, and the clamping jaw 65 and the medical device 9 are lifted.
