Description

Technical Field

[0001] The utility model relates to the technical field of CNC processing equipment, in particular to a novel disc tool magazine. Background Art

[0002] At present, the tool magazines of CNC machining centers on the market generally use ordinary motors to drive roller cams to drive ball-type indexing mechanisms to index and achieve tool change. This type of tool magazine is also used in drilling and tapping machining centers, but this type of tool magazine has the following main disadvantages: First, ordinary motors, roller cams, and ball-type indexing mechanisms mainly rely on sensors for positioning, which has low positioning accuracy and a high failure rate. In addition, iron filings, oil stains, etc. often adhere to the sensors, causing false alarms in the equipment and affecting processing efficiency. Second, the roller cam transmission torque is small, the speed is slow, and the transmission ratio is also small. The roller cam is a consumable part, wears quickly, has a short service life, and is prone to motor burnout, resulting in high maintenance costs. Third, the fastest tool change speed of a conventional tool magazine is within 2 seconds, which can no longer meet the current requirements for efficient processing.

[0003] In response to the above problems, publication number CN201710254583.4 discloses an intelligent high-precision fast tool-changing servo tool magazine, which uses a servo motor as a power drive and a reduction device as a reduction transmission. It has precise positioning and can increase the tool-changing speed by 4-5 times, which is beneficial to improving the efficiency and processing accuracy of the entire drilling and tapping process. However, the tool magazine still has the following problems: the existing tool magazine only uses the motor cover and the cutter head cover to store and protect the tool holder. When the cutter head cover is provided with a recess, the tool holder stationary in the tool magazine is exposed outside the machining center. When the machining center is working, it will generate chips or coolant splashing, causing the surface of the tool holder stationary on the tool magazine to adhere to the impurities of chips or coolant. Due to the impurities on the surface of the tool holder, the subsequent installation accuracy of the tool holder with the spindle is affected, thereby affecting the subsequent machining accuracy.
