[0034] Figure 1 The milling tool shown in the present application is shown in the vertical structure schematic diagram of the front view direction. Figure 2 The locking pin of the milling tool adapted to the present application is shown in the structure schematic diagram of the front view direction. 3 shows the structure schematic diagram of the locking pin of the milling tool adapted to the present application in the side view direction. Please refer to Figure 1 、 Figure 2 and Figure 3The milling groove tool includes a positioning seat 3 provided with a clamping plate 32. A gap 36 is formed between the clamping plate 32 and the positioning seat 3, and the locking pin 7 is clamped through the gap 36 between the positioning seat 3 and the clamping plate 32. A fixing seat 2 is sleeved on the positioning seat 3. The fixing seat 2 is provided with an adjusting rod 4 which contacts the clamping plate 32. The position of the adjusting rod 4 on the fixing seat 2 is adjusted, so that the distance between the clamping plate 32 and the positioning seat 3 is adjusted, and the gap 36 between the clamping plate 32 and the positioning seat 3 is adjusted to clamp the locking pin 7. A cover plate 5 is covered on the positioning seat 3. The cover plate 5 is provided with a positioning hole 52 which communicates with the gap 36. The position of the locking pin 7 in the vertical direction along the positioning hole 52 on the cover plate 5 is fixed. Among them, the adjusting rod 4 is moved towards the positioning seat 3. The adjusting rod 4 drives the clamping plate 32 to move, and the gap 36 between the clamping plate 32 and the positioning seat 3 is narrowed. The clamping plate 32 and the positioning seat 3 are further provided with an elastic member 34. The extension direction of the elastic member 34 is perpendicular to the positioning seat 3 and the clamping plate 32. After processing is completed, the elastic member 34 drives the clamping plate 32 and the positioning seat 3 to move away from each other after the adjusting rod 4 and the clamping plate 32 are moved away, that is, the clamping plate 32 is automatically reset to release the locking pin 7, so that the processed locking pin 7 is conveniently taken out.
[0035] Preferably, the adjusting rod 4 can be a ball head screw with a spherical head at the end of the rod portion 72, and the elastic member 34 can be a spring. The ball head screw abuts against the elastic member 34 through the spherical head at the end. The outer circular arc surface of the spherical head contacts the elastic member 34, and the contact area is larger, so that the stability of force transmission between the adjusting rod 4 and the elastic member 34 is improved.
[0036] Please refer to Figure 1 and Figure 2 The first limiting hole 31 is formed on the positioning seat 3, and the second limiting hole 321 is formed on the clamping plate 32, which are close to the gap 36. The axes of the first limiting hole 31 and the second limiting hole 321 coincide. The elastic member 34 extends into the first limiting hole 31 and the second limiting hole 321 at the same time. The position of the elastic member 34 is fixed through the first limiting hole 31 and the second limiting hole 321.
[0037] Preferably, limiting screw holes 33 are formed on the positioning seat 3 and the clamping plate 32 along the axial direction of the first limiting hole 31, which communicate with the first limiting hole 31 and the second limiting hole 321. Limiting screws 35 are arranged in the limiting screw holes 33, respectively. The length of the limiting screw 35 extending into the limiting screw hole 33 can be accurately adjusted by rotating the limiting screw 35 in the limiting screw hole 33. At the same time, the limiting screw hole 33 also communicates with the first limiting hole 31 and the second limiting hole 321, that is, by adjusting the depth of the limiting screw 35 extending into the limiting screw hole 33, the elastic member 34 can be pre-compressed or relaxed, and then the size of the elastic force of the elastic member 34 is adjusted, so that the positional relationship between the positioning seat 3 and the clamping plate 32 is adjusted.
[0038] More preferably, one first limiting hole 31 and one second limiting hole 321 form a group. Two groups of first limiting holes 31 and second limiting holes 321 are arranged between the positioning seat 3 and the clamping plate 32. Each group of first limiting holes 31 and second limiting holes 321 is provided with an elastic piece 34. The two elastic pieces 34 more evenly and stably support the gap 36.
[0039] Figure 4 A top view structural schematic diagram of the slot milling tool of an embodiment of the present disclosure is shown. Please refer to Figure 1 、 Figure 2 and Figure 4 The inner wall of the fixed seat 2 is bent to form a step 21. The step 21 contacts the surface of the positioning seat 3 away from the base 1. The step 21 cooperates with the base 1 to clamp the position of the positioning seat 3 on the base 1.
[0040] Preferably, the base 1 is also provided. The fixed seat 2 and the positioning seat 3 are arranged on the base 1. A U-shaped groove 11 is formed on the base 1. The base 1 can be conveniently fixed on the machining table through the U-shaped groove 11, and the position relationship between the base 1 and the installation table can be conveniently adjusted through the arrangement of the U-shaped groove 11.
[0041] More preferably, when the clamping plate 32 contacts the fixed seat 2, the width of the gap 36 is the largest. The maximum width of the gap 36 is wider than the thickness b of the lock pin 7 at the sector plate 73. The maximum width of the gap 36 is narrower than the width a of the lock pin 7 at the sector plate 73. The direction of the lock pin 7 extending into the gap 36 is limited, only allowing the thickness direction of the lock pin 7 to extend into the gap 36 to be clamped by the positioning seat 3 and the clamping plate 32, avoiding the rotation angle of the lock pin 7 being wrong, causing the machining direction of the slot 711 to be wrong, and thus reducing the scrap rate.
[0042] Figure 5 A vertical section structural schematic diagram of the cover plate in the slot milling tool of an embodiment of the present disclosure is shown in the front view direction. Please refer to Figure 1 、 Figure 2 and Figure 5 The positioning hole 52 away from one end of the positioning seat 3 has a gradually expanding hole section 521. The hole section 521 cooperates with the head 71 of the lock pin 7 to limit the position of the lock pin 7 on the cover plate 5 in the vertical direction.
[0043] Preferably, the positioning pin 51 is also arranged on the cover plate 5. After the positioning pin 51 passes through the cover plate 5, it extends into the positioning seat 3 or the fixed seat 2. Specifically, the positioning seat 3 or the fixed seat 2 is provided with a pin hole for the positioning pin 51 to be clamped into. Through the positioning pin 51 and the pin hole, the position of the cover plate 5 can be quickly fixed, and the assembly efficiency of the entire slot milling tool is improved.
[0044] More preferably, the fixed seat 2 and the base 1, and the cover plate 5 and the positioning seat 3 are connected by threaded fasteners 6 respectively.
[0045] The specific working process of the utility model is as follows:
[0046] First, rotate the limiting screw 35, adjust the depth of the limiting screw 35 inserted into the limiting screw hole 33, to adjust the pre-tightening force of the elastic member 34 to the appropriate size. Then extend the locking pin 7 into the gap 36 along the positioning hole 52. Adjust the position of the adjusting rod 4, drive the clamping plate 32 to the positioning seat 3 through the adjusting rod 4, narrow the width of the gap 36, until the clamping plate 32 and the positioning seat 3 clamp the locking pin 7. At this time, the locking pin 7 is completely positioned, and a slot 711 can be machined. After the slot 711 is machined, the position of the adjusting rod 4 is retreated. At this time, the elastic member 34 drives the clamping plate 32 away from the positioning seat 3, and the locking pin 7 is no longer clamped by the clamping plate 32 and the positioning seat 3, and the locking pin 7 is removed, completing the machining of the locking pin 7.
