Description

Technical Field

[0001] The invention relates to the technical field of pulley processing machine tools, in particular to a combined machine tool for processing pulleys. Background Art

[0002] As a key component in the field of mechanical transmission, the processing quality and efficiency of pulleys directly affect the performance and reliability of the entire mechanical system. With the rapid development of the manufacturing industry and the intensification of market competition, the requirements for pulley processing machines are also increasing. High-precision, high-efficiency, and high-automation processing machines have become an urgent need in the market.

[0003] A common pulley has at least one recess (such as Figure 8 As shown in the figure, since the pulley is generally a metal part and usually, as a kind of accessory product, most manufacturers only polish the outer sides of the pulley, resulting in the presence of certain bumps or burrs on the inner side of the embedded part, which intensifies the friction of the transmission belt during operation, easily causes the contact part of the transmission belt to break, accelerates the aging of the belt, greatly shortens the service life of the belt, and poses a safety hazard of sudden breakage. At this time, it is necessary to remove the local bumps / burrs on the pulley.

[0004] The common operation is to place the defective pulley separately on the cutting machine or the burr removal machine for processing. However, some pulleys are large in size and weight, which makes it inconvenient to lift, align and stabilize them. A separate lifting device is required. However, due to the large size of the pulleys, the lifting space reserved between the lifting base on the lifting device and the processing area is large, which makes the lifting distance and time of the smaller pulleys before processing longer. Not only is the efficiency low, but the pulley is also prone to fall during the long-distance lifting process.

[0005] In addition, the lifting device is moved to the side of the processing machine tool, and the matching degree is not very high. At the same time, the processed pulley also needs to be sent to a third cleaning machine tool for cleaning operations, etc. Therefore, the existing technology uses multiple independent machine tools or devices with general matching degrees. It is difficult to achieve high precision and high efficiency requirements, and improvement is needed. Summary of the invention

[0006] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, a combined machine tool for processing pulleys is provided.

[0009] A trapezoidal hollow structure is provided on the panel on one side of the burr removal area and below the rotating shaft assembly. The trapezoidal hollow structure includes a plurality of insertion slots corresponding to the positions of the burr removal rollers respectively.

[0010] By adopting the above technical solution, the position and height of the insertion groove match the height of the burr removal roller at the corresponding position, and the size nameplate of the corresponding pulley can be affixed as needed, so that the operator can find the corresponding slot in time and directly insert the matching pulley to be processed during processing.

[0011] The inner bottom of the body is also provided with a hydraulic lifting mechanism, which includes a hydraulic press installed at the bottom of one side of the burr removal area in the body, and the upper side of the output end of the hydraulic press is connected to a pulley positioning platform through a lifting column, and the pulley positioning platform is equidistantly provided with positioning blocks corresponding to the positions of the insertion groove and the burr removal roller respectively;

[0012] By adopting the above technical solution, the pulley positioning platform can not only locate and limit the pulley to be processed, but also greatly improve the operating efficiency and facilitate quick thorn removal operations because the distances that pulleys of various sizes need to be lifted are the same and shorter.

[0021] By adopting the above technical solution, it is convenient for the operator to hold the pulley to be processed for placement and support operations while starting the hydraulic press below, ensuring that the thorn removal operation is completed quickly and improving work efficiency.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. The present invention integrates a set of compact and efficient modular machine tools for removing burr points of defective pulleys, which combines the burr removal machine tool, hydraulic lifting device, cooling mechanism and dust removal device together. Compared with the independent use in the prior art, the matching degree is higher, the structure is more compact, and the work efficiency is greatly improved;

[0024] 2. Multiple rotating shafts and burr removal rollers with oblique directions are used to correspond to several commonly used pulleys of different sizes, so that the initial installation height of the lifting and positioning platform below can remain unchanged. Moreover, no matter which size of pulley is used, after being placed in the corresponding slot, the lifting distance of the lifting and positioning platform below is the same. Therefore, the operation of placing the pulley during grinding is greatly simplified. Moreover, since the lifting distance only needs to be small and consistent, the time of lifting to the middle of the upper grinding wheel is shortened, thereby improving the processing efficiency.

[0025] 3. A dust removal area is added on the other side of the thorn removal area. The upper side of the drum is used for rolling transmission. The dust is removed while the vacuum cleaner is used. The operation is convenient and the dust removal effect is good.

[0026] 4. A cooling mechanism is added to the burr removal area. Cooling water is accurately and controlledly dripped into the corresponding position above each burr removal roller, effectively flushing and cooling the grinding point. BRIEF DESCRIPTION OF THE DRAWINGS
