The periphery of the cutter head 1 is milled with a plurality of arc concave hole-shaped tool slots 101, and a spring clip 2 is locked between every two tool slots 101, and each tool slot 101 is also locked. All locks have a pressing plate part 3. Although this tool magazine device can achieve the purpose of tool clamping, it actually has the following problems:

1. Milling a plurality of sipes 101 symmetrical to the central axis of the cutter head 1 on the periphery of the cutter head 1 is not only difficult to process but requires high precision and relatively high cost.

2. If one tool slot 101 is damaged, it is necessary to stop the machine and remove the entire tool magazine device, and then detach all the spring clips 2 and pressure plate parts 3 from the cutter head 1 in order to fix the cutter head 1. Make repairs. After waiting for the refurbishment of the cutter head 1, the spring clips 2, the pressing plate parts 3, etc. must be reinstalled on the cutter head 1, so the maintenance is quite troublesome.

Three, moreover, when processing, iron filings are easy to spray and fall on the top surface of the cutter head 1 and the top surface rim of the sipes 101, and when the cutter is inserted into the sipes 101, the The axis of the tool is deflected due to iron filings, and once the tool is selected for tool setting, it will cause the tool to be unable to be smoothly inserted into the main shaft of the processing machine.

【Detailed ways】

As shown in Figure 2 and Figure 3, the preferred embodiment of the cutter head clamping arm device 100 of the present invention is detachably fixed on the periphery of a cutter head 200, and can hold and position a cutter 300, the cutter 300 It has a cylindrical part 310, a tapered cylindrical part 320 arranged on one side of the cylindrical part 310 along the axis, the cylindrical part 310 has a ring groove 330 recessed on the outer peripheral surface, two 180-degree intervals and arranged on the cylindrical part 310 along the axis. The locking groove 340 on one side of the ring groove 330 . And the clamp arm device 100 includes a positioning seat 10, a spring clip 20 fixed on the positioning seat 10, two locking units 30 that can press and position the spring clip 20 on the positioning seat 10, and a spring clip 20 that is fixed on the positioning seat 10. The cutter 300 triggers the shutter 40 that can slide relative to the positioning seat 10 and an elastic element 50 that provides a recovery action after the shutter 40 slides.

The positioning seat 10 has a centerline L that can extend and intersect with the axis of the cutter head 200, a fixed end 11 corresponding to one end of the center line L and fixed on the cutter head 200, and a pair of the other end of the center line L and connected to the cutter head 200. The fixed end portion 11 is oppositely provided with a supporting end portion 12, a chute 13 arranged at the bottom and extending along the midline L, a groove 14 arranged above the chute 13 and extending along the midline L, two sets of A stopper 15 below the chute 13 and a U-shaped slot 16 arranged on the top. The receiving end 12 has a recessed hole 121 that is concave toward the inside along the centerline L, and a socket portion 122 that is protruded on the inner ring surface of the recessed hole 121 and can be nested by the ring groove 330 of the tool 300 And a clamping plate 123 which is fixed on the socket portion 122 by screws and can be extended in the clamping slot 340 .

The spring clip 20 is generally U-shaped, just embedded in the slot 16 of the positioning seat 10, and has a connecting piece 21 fixed on the positioning seat 10 and perpendicular to the midline L and two connecting pieces respectively connected to the positioning seat 10. The two ends of the connecting piece 21 are respectively arranged on the clip pieces 22 on both sides of the centerline L. As shown in FIG. Each of the clip pieces 22 has a clamping end 221 elastically clamped on the cylindrical portion 310 of the tool 300 , and the clamping end 221 is wound into a ring shape.

Each of the locking units 30 has a washer 31 pressed on the middle section of the clip piece 22 of the spring clip 20 and a screw 32 passing through the washer 31 and screwed on the positioning seat 10 .

The locking portions 42 on both sides of the bottom surface can abut against the stoppers 15 in good time.

The elastic element 50 is installed between the positioning seat 10 and the push block 41 , and is just sleeved in the groove 14 , and its elastic force can make the shield 40 cover the bottom of the concave hole 121 .

As shown in Fig. 4 and Fig. 5, under normal conditions (that is, when the tool 300 has not been inserted), the shutter 40 is subjected to the elastic force of the elastic element 50, and will be covered under the concave hole 121, and the shutter 40 By abutting against the stoppers 15 by the locking portions 42 , a positioning effect can be generated relative to the positioning seat 10 .

As shown in Fig. 6 and Fig. 7, when the cutter 300 is inserted into the concave hole 121, the shield 40 can be pushed and pulled by the cutter 300, so that the shield 40 can be shielded from a shield originally under the concave hole 121. position, and move toward the fixed end portion 11 to an open position. At this time, the locking portion 42 is far away from the stopper 15, and utilizes the sheathing of the ring groove 330 and the sleeve portion 122, the locking plate 123 and the locking The embedding of the groove 340 and the clip piece 22 being clamped on the cylindrical portion 310 by elastic bundles can make the tool 300 be stably fixed.

Therefore, the utility model has the following advantages:

1. The 200 cutterheads are simply made into a disc shape, and the clamping arm device 100 is mass-produced in a modular manner. After the production and assembly are completed, it is then locked on the periphery of the cutterhead 200, so the clamping arm The center line L of the device 100 can be accurately aligned with the center axis of the cutter head 200 . Moreover, the manufacturing and processability of the clamping arm device 100 are not only relatively easy, but also the cost is relatively low.

2. If a clamp arm device 100 is damaged, only the damaged clamp arm device 100 needs to be removed from the cutter head 200, and a new clamp arm device 100 can be replaced immediately, so it will not affect the operation of the processing machine. Maintenance is quite easy, time-saving, and does not affect productivity.

3. In the state shown in FIG. 4 , when the clamping arm device 100 has not yet clamped the tool 300 , the shutter 40 is in the shielded position to prevent iron filings from spraying through the concave hole 121 and falling to the positioning seat 10 top, and can ensure that the cutter 300 remains accurate when inserted.

To sum up the above, the cutter head clamping arm device of the utility model is mass-produced in a modular manner, and is detachably assembled on the cutter head. purpose of the utility model.
