Description

Technical Field

[0001] The utility model belongs to the technical field of ring-shaped piece cutting, in particular to a special sawing machine for cutting ring-shaped pieces. Background Art

[0002] The steel pipe is a ring-shaped part with a hollow middle part. A band saw is generally used to cut the ring-shaped part. The traditional band saw has a base, a saw frame, a lifting mechanism, a saw blade, a driving mechanism, and a clamping mechanism. During processing, the ring-shaped part to be cut is clamped and fixed on the base by the clamping mechanism, and the saw blade is driven to move by the driving mechanism. The lifting mechanism brings the saw frame and the saw blade close to the ring-shaped part to cut the ring-shaped part. For the cutting of the ring-shaped part, the saw blade needs to cut from the starting point on the outer wall of the ring-shaped part to the end point of the outer wall on the other side opposite to the starting point in the diameter direction of the ring-shaped part, that is, the saw blade needs to cut the entire diameter of the ring-shaped part in one stroke. This has low cutting efficiency and causes greater wear on the saw blade. Therefore, the traditional band saw needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to provide a special sawing machine for cutting annular parts in order to solve the above-mentioned technical problems. The sawing machine can drive the annular parts to rotate during the cutting process. The saw blade only needs to travel to the radius distance of the annular part in one cutting stroke to cut the entire annular part, and the cutting efficiency is high.

[0004] In view of this, the utility model provides a special sawing machine for cutting ring-shaped parts, comprising:

[0005] A base, a saw frame is arranged above the base, and a saw blade and a driving mechanism for driving the saw blade to move are arranged on the saw frame;

[0006] A lifting mechanism, the lifting mechanism is used to drive the saw frame to rise and fall;

[0007] The rotating clamping mechanism can clamp the annular part and can rotate with the annular part;

[0008] The translation mechanism is arranged on the base, the translation mechanism can move along the axial direction of the annular member, and the rotating clamping mechanism is arranged on the translation mechanism.

[0009] In the present technical solution, the annular part is clamped and fixed by a rotating clamping mechanism, and then the annular part is adjusted to a suitable position by a translation mechanism so that the position of the annular part to be cut is opposite to the position of the saw blade. Then the rotating clamping mechanism causes the annular part to rotate, and the driving mechanism drives the saw blade to move into a cutting state. The lifting mechanism drives the saw frame, the saw blade and the driving mechanism to descend close to the annular part. After the saw blade contacts the annular part, it continues to cut downward to the radius distance of the annular part, and the annular part can be cut off as a whole along the diameter direction.

[0010] In the above technical solution, further, the rotating clamping mechanism includes:

[0011] A clamping chuck, on which a plurality of clamping claws are distributed in a circumferential direction, and the plurality of clamping claws cooperate to clamp the inner wall of the annular member;

[0012] A power source is used to drive the clamping chuck to rotate.

[0013] In the above technical solution, further, the translation mechanism includes:

[0014] Track, the length direction of the track is the same as the axial direction of the ring-shaped member, and the transverse section of the track is U-shaped;

[0015] A sliding seat, the bottom of which is slidably connected with both ends of the U-shaped track along the axis direction of the ring-shaped member, and a transmission plate is provided on the bottom surface of the sliding seat;

[0016] The push cylinder is arranged in the middle of the track, and the movable end of the push cylinder is connected with the transmission plate.

[0017] In the above technical solution, further, a fixed plate is provided on the transmission plate, and a plurality of fixed teeth are distributed at intervals along the axial direction of the annular part on the fixed plate; a locking plate is provided on one side of the fixed plate, and a plurality of locking teeth are distributed at intervals along the axial direction of the annular part on the locking plate, and a locking cylinder for driving the locking plate to approach and move away from the fixed plate is provided on the base, and when the locking plate approaches the fixed plate, at least two fixed teeth can engage with at least two locking teeth.

[0019] A support frame, the support frame is arranged on the saw frame;

[0020] A lifting cylinder, the lifting cylinder is arranged on the base, and the movable end of the lifting cylinder is connected to one end of the support frame;

[0021] The guide column is arranged on the base, and a guide seat is provided on the guide column for sliding along the vertical direction, and the guide seat is connected to the other end of the support frame.

[0022] In the above technical solution, further, a circle of baffles is provided on the base around the outline of the base.

[0023] The beneficial effects of the utility model are:

[0024] 1. Through the setting of the rotating clamping mechanism, the annular piece can be rotated during the cutting process. Through the setting of the translation mechanism, the cutting position of the annular piece can be adjusted, so that the annular piece can be clamped once and cut multiple times. In the cutting process, the saw blade only needs to move to the radius distance of the annular piece in one trip, and the entire annular piece can be cut along the diameter direction, which has high cutting efficiency and reduces the wear of the saw blade.

[0025] 2. By designing the rotating clamping mechanism into a clamping chuck and cooperating with a plurality of claws to clamp and fix the inner wall of the annular part, the utility model can also be adapted to the cutting of annular parts with larger outer diameters, and has a wider range of applications.

[0026] 3. A locking mechanism is formed by setting a fixed plate, multiple fixed teeth, a locking plate, multiple locking plates, and a locking cylinder. When the sliding seat slides horizontally, the locking mechanism unlocks the sliding seat. After the sliding seat is adjusted to a suitable position, the locking mechanism locks the sliding seat, thereby improving the stability of the annular part during the cutting process.

[0042] The lifting mechanism 5 is used to drive the saw frame 2 to rise and fall. Figure 2 In this embodiment, the lifting mechanism 5 includes: a support frame 501, a lifting cylinder 502, and a guide column 503.

[0043] The support frame 501 is fixed on the saw frame 2; the lifting cylinder 502 is arranged on the base 1, the lifting cylinder 502 is vertically oriented, and the movable end of the lifting cylinder 502 is connected to one end of the support frame 501; the guide column 503 is arranged on the base 1, and a guide seat 504 is provided on the guide column 503 to slide in the vertical direction, and the guide seat 504 is connected to the other end of the support frame 501;

[0059] See also Figure 2 In this embodiment, the translation mechanism 7 includes: a track 701, a sliding seat 702, and a push cylinder 704.

[0060] The length direction of the track 701 is the same as the axial direction of the ring-shaped member 100, and the transverse cross section of the track 701 is U-shaped;

[0061] The bottom of the sliding seat 702 is slidably connected with the two ends of the U-shaped track 701 along the axial direction of the ring-shaped member 100. The bottom surface of the sliding seat 702 is provided with a transmission plate 703. Figure 2 The middle transmission plate 703 is blocked and not shown;

[0062] The push cylinder 704 is disposed in the middle of the track 701, and is oriented horizontally. The movable end of the push cylinder 704 is connected to the transmission plate 703.

[0063] In this embodiment, the push cylinder 704 starts to drive the active end to move axially, and the active end of the push cylinder 704 drives the transmission plate 703 to move axially along the annular member 100. During this process, the transmission plate 703 slides horizontally on the track 701 with the sliding seat 702, thereby adjusting the position of the annular member 100 in the axial direction.

[0064] Example 4

[0065] This embodiment provides a sawing machine dedicated to cutting annular parts. In addition to the technical solutions of the above embodiments, a locking mechanism is provided on the basis of the translation mechanism 7.

[0067] When these locking teeth 12 are engaged with these fixed teeth 10, the movement of the transmission plate 703 is restricted, thereby locking the sliding seat 702. In this way, during the cutting process of the annular part 100, the sliding seat 702 is in a locked state, which can improve the cutting stability of the annular part 100; when it is necessary to adjust the position of the annular part 100 in the axial direction, the locking cylinder 13 starts to drive the movable end to move axially, and the movable end of the locking cylinder 13 will drive the locking plate 11 away from the fixed plate 9, so that the locking teeth 12 are separated from the fixed teeth 10. At this time, the sliding seat 702 is unlocked, and the sliding seat 702 can be driven by the push cylinder 704 to slide along the axial direction of the annular part 100.
