The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components.
The utility model will now be further described with reference to the drawings and detailed description.
Referring to fig. 1 to 8, the cutter processing device provided in this embodiment includes a rotary table 10, and an upper and lower feeding mechanism 31 and a processing mechanism 32 disposed on the periphery of the rotary table 10, specifically, four stations are uniformly disposed on the periphery of the rotary table 10, namely, an upper and lower feeding station and three processing stations, the upper and lower feeding mechanism 31 corresponds to the upper and lower feeding stations, the number of the processing mechanisms 32 is three, and three processing mechanisms 32 correspond to three processing stations one by one, specifically, the upper and lower feeding mechanism 31 and the processing mechanisms 32 refer to CN 108723901A and CN 109940466A, which are not described in detail herein.
The rotary table 10 is provided with clamping devices 20, specifically four clamping devices 20, for clamping the tool 2, and the clamping devices 20 are uniformly distributed on the periphery of the rotary table 10, and rotation of the rotary table 10 drives the clamping devices 20 to switch between the feeding and discharging mechanism 31 and the processing mechanism 32 (i.e., alternately switch between four stations).
Of course, in other embodiments, the number of the clamping devices 20, the number and arrangement of the loading and unloading mechanisms 31 and the processing mechanism 32, and the like may be arranged according to the specific situation.
Specifically, the clamping device 20 is provided with a driving end (i.e. an inner arm section 221 of the clamping arm 22 in the drawing) for releasing the clamping state and a through hole 201 corresponding to the driving end, and when the clamping device 20 is switched to the feeding and discharging station, the clamping device 20 is driven to release the clamping state by the thimble 42 of the thimble mechanism 40 penetrating through the through hole 201 and propping against the driving end. Therefore, when the cutter 2 is required to be clamped or dismounted, the clamping state can be actively released, so that the operation of clamping or dismounting the cutter 2 is simpler and easier, the mutual abrasion is avoided, the qualification rate of the cutter 2 is effectively improved, and the service life of the clamping device 20 is effectively prolonged.
The clamping device 20 comprises a clamping head 21, a clamping arm 22 and a spring 23, wherein the clamping head 21 is provided with an insertion hole 212, the middle position of the clamping arm 22 is hinged in the insertion hole 212 of the clamping head 21, the spring 23 is arranged between the clamping head 21 and an inner arm section 221 of the clamping arm 22 so as to apply a clamping force to an outer arm section 222 of the clamping arm 22, and as shown in fig. 6, the spring 23 applies a downward force to the inner arm section 221 of the clamping arm 22 so as to apply an upward clamping force to the outer arm section 222 of the clamping arm 22; and further drives the outer arm section 222 of the clamping arm 22 to clamp the tool 2. The inner arm section 221 of the clamping arm 22 forms a driving end for releasing the clamping state; the through hole 201 corresponding to the driving end includes a first through hole 211 formed in the clamping head 21, the first through hole 211 always corresponding to the inner arm section 221. When the clamping state needs to be released, the ejector pin 42 passes through the first through hole 211 and abuts against the inner arm section 221 of the clamping arm 22, so that the ejector pin overcomes the elastic force of the spring to move, and the outer arm section 222 of the clamping arm 22 is driven to open downwards, so that the clamping state is released. When clamping is desired, the ejector pin 42 is removed and the outer arm segment 222 of the clamp arm 22 is spring-biased to switch back to the clamped state.

In this way, the motor 26 can drive the clamping head 21 and the tool 2 thereon to rotate through the rotating shaft assembly 25 so as to cooperate with machining. When switching to the corresponding loading and unloading station, the motor 26 drives the clamping head 21 to rotate to the initial position, namely the first through hole 211 and the second through hole 241 are corresponding, so that the thimble 42 sequentially passes through the second through hole 241 and the first through hole 211 to prop against the driving end. Of course, in other embodiments, the structure of the clamping device 20 is not limited to this, for example, the first through hole 211 is located outside the fixed cover assembly 24, so the fixed cover assembly 24 does not need to be provided with the second through hole 241, i.e. the through hole 201 corresponding to the driving end only has the first through hole 211.
