[0007] Beneficial effects: 1.

[0008] 2. The outer positioning claw and the inner positioning claw of the present invention synchronously clamp the inner wall and the outer wall of the special thin-walled tubular part of the concrete mixer, and the clamping force of the outer positioning claw and the inner positioning claw at the corresponding position is provided by the same clamping drive hydraulic cylinder, so that the force on the inner wall and the outer wall of the thin-walled tubular part itself is more balanced when clamped, thereby avoiding the uneven surface of the thin-walled tubular part due to uneven force during the positioning of the thin-walled tubular part, so that the clamping effect of this device when facing special thin-walled tubular parts is better.

[0009] 3. The present invention uses the spring design between the main traction rod and the auxiliary traction rod and the sliding design between the driven unlocking block and the active unlocking block, so that when the displacement driving hydraulic cylinder drives the turning tool to shift, the locking block will be lifted first, and the turning tool can continue to rotate only after the locking column is disconnected from the inner locking connecting groove. After the turning tool is shifted, the locking column will automatically be inserted into the inner locking connecting groove to position the turning tool, so that the shifting and positioning are synchronously completed by the displacement driving hydraulic cylinder through a power source, so that the displacement and positioning process can be carried out efficiently, accurately and stably, and the probability of jamming and failure is reduced.

[0010] 4. The sliding tool positioning block of the present invention is closer to the tool head part of the turning tool when it is in the outer wall turning state, and the distance between the sliding tool positioning block and the tool mounting block is larger, so that the torque exerted on the tool mounting block and the sliding tool positioning block during the turning operation of the turning tool is smaller, and the turning process is more stable.

[0011] 5. The sliding tool positioning block of the present invention in the outer wall turning state is farther away from the tool head of the turning tool, so that more of the turning tool is exposed to the outside, so that the turning tool can penetrate a longer distance when turning the inner wall of the thin-walled tubular part of the concrete mixer, so that the device can complete the turning operation of thin-walled tubular parts of larger sizes, thereby increasing the processing range of the device.

When the outer wall turning state is changed to the inner wall turning state, the hydraulic rod of the displacement driving hydraulic cylinder 55 pulls the hydraulic cylinder connecting block 60 close to the displacement driving hydraulic cylinder 55, so that the main pulling rod 73 is close to the auxiliary pulling rod 71. At this time, the locking column 58 is inserted into the inner locking connection block 60. The inside of the groove 80 positions the sliding tool positioning block 35, so that the positions of the tool mounting block 37 and the sliding tool positioning block 35 cannot be changed, so that the spring between the main traction rod 73 and the auxiliary traction rod 71 is compressed, and synchronously, when the hydraulic cylinder connecting block 60 approaches the displacement driving hydraulic cylinder 55, the active unlocking block 62 of the hydraulic cylinder connecting block 60 drives the driven unlocking block 44 to approach the unlocking block positioning platform 40, so that the lifting driving block 47 of the driven unlocking block 44 approaches the displacement driving hydraulic cylinder 55, and the lifting driving block 47 approaches the displacement driving hydraulic cylinder 55. The hydraulic cylinder 55 is driven by the lifting connecting rod 49 to drive the locking block 50 to be lifted as a whole, until the locking column 58 of the locking block 50 is disconnected from the inner locking connecting groove 80. After the locking column 58 is disconnected from the inner locking connecting groove 80, the sliding tool positioning block 35 can rotate freely. At this time, the spring between the main traction rod 73 and the auxiliary traction rod 71 is relaxed, and the main traction rod 73 controls the sliding tool positioning block 35 around the tool positioning block mounting platform through the connecting rod structure composed of the auxiliary traction rod 71 and the displacement driving connecting rod 67. 65 continues to rotate until the sliding tool positioning block 35 rotates 80°, the active unlocking block 62 is disconnected from the driven unlocking block 44, and the driven unlocking block 44 continues to have a reset tendency under the influence of the spring between the unlocking block positioning groove 41 and the unlocking block positioning column 42, so that the locking column 58 slides on the surface of the sliding tool positioning block 35 until the sliding tool positioning block 35 is completely deflected 90°, the locking positioning block 52 at the corresponding position is connected to the inner locking connection groove 80, the driven unlocking block 44 is completely reset, and the displacement of this device is completed. During the processing, the force is balanced to prevent the chipping phenomenon caused by excessive cutting force, the operation is stable, and the rough processing surface is prevented.

[0038] It should be noted that the position of the turning tool 34 is controlled by the connecting rod mechanism composed of the displacement driving block 63, the main traction rod 73, the auxiliary traction rod 71, the displacement driving connecting rod 67, etc. driven by the displacement driving hydraulic cylinder 55, so that this device can perform the turning operation of the outer wall of the thin-walled tubular part 2 and the inner wall of the thin-walled tubular part 2 when only one turning tool 34 is installed, thereby reducing the tool requirements of this device when processing the thin-walled tubular part 2, thereby reducing the use and production costs of this device.

[0039] It should also be noted that, through the spring design between the main traction rod 73 and the auxiliary traction rod 71 and the sliding design between the driven unlocking block 44 and the active unlocking block 62, when the displacement driving hydraulic cylinder 55 drives the turning tool 34 to shift, the locking block 50 will be lifted first, until the locking column 58 is disconnected from the inner locking connection groove 80, and the turning tool 34 can continue to rotate. After the displacement of the turning tool 34 is completed, the locking column 58 will automatically insert into the inner locking connection groove 80 to position the turning tool 34, so that the displacement and positioning are completed synchronously by the displacement driving hydraulic cylinder 55 through a power source, so that the displacement and positioning process is carried out efficiently, accurately and stably, and the probability of jamming and failure is reduced. The present invention operates stably, prevents unstable cutting, excessive cutting depth and feed, and vibration caused by intermittent cutting, avoids a sudden increase in cutting depth, and the occurrence of knife piercing or bamboo knot patterns.

[0040] It should also be noted that the sliding tool positioning block 35 in the outer wall turning state is closer to the tool head part of the turning tool 34, and the distance between the sliding tool positioning block 35 and the tool mounting block 37 is larger, so that the torque exerted on the tool mounting block 37 and the sliding tool positioning block 35 during the turning operation of the turning tool 34 is smaller, and the turning process is more stable.

[0041] It should also be noted that the sliding tool positioning block 35 in the outer wall turning state is farther away from the tool head of the turning tool 34, so that more of the turning tool 34 is exposed to the outside, so that the turning tool 34 can penetrate a longer distance when turning the inner wall of the thin-walled tubular part 2, so that this device can complete the turning operation of thin-walled tubular parts 2 of larger sizes, thereby increasing the processing range of this device.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
