DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1, reference Figure 1, is the first embodiment of the present invention, which provides a processing device for an expansion joint collar, comprising a support unit 100, the support unit 100 comprising an operating table 101, a support device, a support seat 102 arranged on the operating table 101, and used to prevent the collar a, the upper surface of the support seat 102 is arc-shaped, so that it can better contact with the collar a and increase the stability of the whole circle; The shaping unit 200 includes a circle centering component 201 disposed on the operating table 101, the circle centering component 201 is horizontally provided with two groups of shaping components 202 disposed on the circle centering component 201, and a control component 203 disposed on the shaping component 202. The circle centering component 201 is used to limit the motion trajectory of the shaping component 202 so that the straight line where the two groups of shaping units 200 are located is kept on the center of the current ring a, and the control component 203 is used to drive the shaping component 202 to make the ring a round. The shaping auxiliary unit 300 includes a movable support assembly 301 disposed on the operating table 101, a shaping auxiliary assembly 302 for supporting and disposed on the movable support assembly 301, and an auxiliary roller 303 disposed on the shaping auxiliary assembly 302. The shaping auxiliary assembly 302 is used to drive the auxiliary roller 303 to adjust the inner wall of the ring a in real time, thereby eliminating stress and maintaining the flatness of the ring a; and The welding unit 400 is used to weld the sleeve ring a which has been completed in a full circle.

[0031] In summary, the semicircular ring a is placed on the support seat 102, and the opening of the ring a is facing upward. At this time, the control component 203 is started to drive the shaping component 202 to move on the center component 201 until the shaping component 202 presses the two sides of the ring a. At this time, the control component 203 is stopped, and the shaping auxiliary component 302 is adjusted to the radius length of the current ring a. At this time, the height of the movable support component 301 is adjusted so that the auxiliary roller 303 is tightly pressed against the inner wall of the ring a. At this time, the shaping auxiliary component 302 is started, and the control component 203 is started again. The ring a is made into a circle through the cooperation of the shaping component 202 and the auxiliary roller 303. When the two sides of the ring a are connected, the welding unit 400 is started to weld the interfaces on both sides. At this time, the shaping component 202 stably clamps the ring a, making the welding process smoother and avoiding empty welding and missing welding.

[0032] Example 2, reference Figure 1-Figure 5, which is the second embodiment of the present invention, and is different from the previous embodiment in that: the ring a is rounded. Compared with the embodiment 1, further, the centering component 201 includes a fixed block 201a disposed on the operating table 101 for support, the fixed block 201a is horizontally provided with two sets of sliding grooves 201b disposed on the fixed block 201a for sliding with the shaping component 202, and a limiting surface 201c disposed on the fixed block 201a for limiting the sliding of the shaping component 202 to ensure the stable operation of the device.

[0033] Among them, the limiting surface 201c is a smooth plane, and the angle between the limiting surface 201c and the operating table 101 is 45°, and the sliding groove 201b is parallel to the limiting surface 201c, so that when the shaping component 202 moves on the fixed block 201a, the horizontal movement distance and the vertical movement distance are increased and decreased synchronously, and the two groups of control components 203 and the center of the current ring a can be kept in a straight line at all times, thereby increasing the stability of the whole circle and avoiding the ring a from popping out and causing damage.

[0034] The shaping assembly 202 includes a connecting plate 202a disposed on the fixed block 201a, which plays a connecting role, and a rounding roller 202b rotatably disposed on the connecting plate 202a, which is used to contact the sleeve ring a to perform a rounding operation; A sliding block 201a-1 is provided on the connecting plate 202a to cooperate with the sliding groove 201b. The sliding block 201a-1 is in an auxiliary shape to facilitate moving back and forth on the sliding groove 201b. A contact block 201a-2 is provided on the connecting plate 202a to cooperate with the limiting surface 201c. The contact block 201a-2 is in contact with the limiting surface 201c to limit the moving state of the connecting plate 202a and prevent the connecting plate 202a from rotating through the sliding block 201a-1.

[0035] The control assembly 203 includes a cavity 203a disposed on the operating table 101, a power piece 203b disposed on the cavity 203a, and a limiting groove 203c disposed on the inner wall of the cavity 203a. The cavity 203a is used as a space for the power piece 203b to move. The power piece 203b is used to drive the connecting plate 202a to move on the fixed block 201a. The limiting groove 203c is used to limit the movement of the power piece 203b. The power member 203b includes a mounting seat 203b-1 disposed in the cavity 203a, a first motor 203b-2 disposed on the mounting seat 203b-1 and slidably connected to the limiting groove 203c, and a control screw 203b-3 disposed at the output end of the first motor 203b-2. The mounting seat 203b-1 is used to support the first motor 203b-2 and cooperate with the limiting groove 203c to accommodate the movement of the first motor 203b-2 and the connecting plate 202a. The control screw 203b-3 is used to cooperate with the first motor 203b-2 to drive the shaping component 202 to move; The connecting plate 202a is provided with an internal thread b that matches the control screw 203b-3.

[0036] The rest of the structure is the same as that of Example 1.

[0037] In summary, when the auxiliary roller 303 is tightly in contact with the inner wall of the ring a, the shaping auxiliary component 302 is started, and the first motor 203b-2 is started again to drive the control screw 203b-3 to rotate. At this time, the control screw 203b-3 drives the connecting plate 202a to move along the trajectory of the full-circle roller 202b, and cooperates with the auxiliary roller 303 to perform a full-circle operation on the ring a. During the process, due to the setting of the sliding groove 201b, the horizontal and numerical movement amounts of the full-circle roller 202b are the same, so the full-circle roller 202b always remains in a straight line with the current center of the ring a, keeping the force on the ring a uniform, and cooperating with the movement of the auxiliary roller 303 to ensure the overall flatness of the ring a and facilitate the subsequent welding operation.

[0038] Example 3, reference Figure 1-Figure 10 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: the shape of the ring a is adjusted in real time to prevent the ring a from being deformed or cracked due to uneven force. Compared with embodiment 1, further, the movable support assembly 301 includes a first support block 301a and a second support block 301b respectively arranged at both ends of the support seat 102, an opening and closing member 301c arranged on the first support block 301a, and a first adjusting member 301d arranged on the first support block 301a and the second support block 301b. The first support block 301a and the second support block 301b are used to support the shaping auxiliary assembly 302, the opening and closing member 301c is used to facilitate the opening of the shaping auxiliary assembly 302, and the ring a is placed on the support seat 102. The first adjusting member 301d is used to adjust the height of the first support block 301a and the second support block 301b, so as to facilitate the adjustment of the position of the auxiliary roller 303.

[0039] The first support block 301a includes a lower support block 301a-1 disposed at one end of the support seat 102, an upper support block 301a-2 disposed on the lower support block 301a-1, and an arc block 301a-3 disposed on the upper support block 301a-2. The lower support block 301a-1 and the upper support block 301a-2 are rotatably connected through an opening and closing member 301c. The arc block 301a-3 is used for limiting and enhancing the stability of the auxiliary roller 303 abutting against the ring a. The opening and closing member 301c includes an installation groove 301c-1 arranged on the lower support block 301a-1, a second motor 301c-2 arranged in the installation groove 301c-1, an output shaft 301c-3 arranged at the output end of the second motor 301c-2, a support shaft 301c-4 arranged on the upper support block 301a-2, and a transmission belt 301c-5 arranged on the output shaft 301c-3 and the support shaft 301c-4. The second motor 301c-2 is used to generate power, and the upper support block 301a-2 is driven to rotate through the transmission of the output shaft 301c-3, the support shaft 301c-4 and the transmission belt 301c-5, thereby controlling the opening and closing of the auxiliary roller 303.

[0040] The shaping auxiliary component 302 includes a third motor 302a disposed on the upper support block 301a-2 for generating power, a support plate 302b disposed at the output end of the third motor 302a for supporting, and a second adjustment member 302c disposed on the support plate 302b for connecting the support plate 302b and the auxiliary roller 303; Both ends of the support plate 302b are rotatably connected to the second support block 301b and the upper support block 301a-2 respectively.

[0041] The second adjusting member 302c includes a connecting sleeve 302c-1 disposed at both ends of the supporting plate 302b, a rotating sleeve 302c-2 disposed in the connecting sleeve 302c-1, a knob 302c-3 disposed on the rotating sleeve 302c-2, an adjusting screw 302c-4 disposed in the rotating sleeve 302c-2, and an intermediate shaft 302c-5 disposed on the adjusting screw 302c-4. The rotating sleeve 302c-2 is rotated to drive the connecting sleeve 302c-1 to rotate, and the adjusting screw 302c-4 is pushed and pulled, so as to adjust the length between the connecting sleeve 302c-1 and the intermediate shaft 302c-5 to achieve the finished product radius of the adapted processed collar a. The rotating sleeve 302c-2 is provided with a threaded hole c that matches the adjusting screw 302c-4; A limit rod d is provided on the connecting sleeve 302c-1, and a matching limit rod d and a limit hole e are provided on the intermediate shaft 302c-5. The limit rod d and the limit hole e cooperate to limit the position; The first adjusting member 301d and the second adjusting member 302c have the same structure.

[0042] The rest of the structure is the same as that of Example 2.

[0043] In summary, when the full-circle roller 202b presses against the two sides of the sleeve a, the first motor 203b-2 is stopped. At this time, the second motor 301c-2 is started to drive the upper support block 301a-2 to rotate until the lower support block 301a-1 and the arc block 301a-3 are tightly abutted and clamped. At this time, the knob 302c-3 is turned to drive the rotating sleeve 302c-2 to rotate, and the length between the connecting sleeve 302c-1 and the intermediate shaft 302c-5 is adjusted until the length between the connecting sleeve 302c-1 and the auxiliary roller 303 is the radius of the finished ring sleeve. At this time, the height of the first support block 301a and the second support block 301b is adjusted by the first adjusting member 301d, and the auxiliary roller 303 is driven to move up and down until it is tightly abutted against the inner wall of the sleeve a. At this time, the second support block 301b is rotated and clamped with the support plate 302b, and the third motor 302a and the first Motor 203b-2, at this time, the auxiliary roller 303 rotates on the inner wall of the ring a with the radius of the finished ring sleeve, and cooperates with the full-circle roller 202b to slowly round the two sides of the ring a, so as to keep the ring a flat during the rounding process, and continuously roll the ring a through the auxiliary roller 303, thereby eliminating the stress generated during the rounding process, avoiding deformation and cracks in the ring a, and ensuring the quality of the finished ring. When the rounding is completed, the auxiliary roller 303 is driven by the third motor 302a to be at the bottom of the ring a. At this time, the two sides of the ring a are neatly connected, and the interface is welded by the welding unit 400. At this time, the full-circle roller 202b stably clamps the two symmetrical points of the ring a, and the auxiliary roller 303 eliminates the stress inside the ring a, thereby ensuring the stability of the welding process, and avoiding the deformation of the ring a and affecting the welding quality.

[0044] Example 4, reference Figure 1-Figure 10 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: the collar a is welded. Compared with the first embodiment, the welding unit 400 further comprises a mounting block 401 disposed on the support plate 302b for supporting, a double-force cylinder 402 disposed on the mounting block 401 for driving the mounting block 401 to move on the support plate 302b, an electric telescopic rod 403 disposed on the double-force cylinder 402 for telescoping, and a welding head 404 disposed on the electric telescopic rod 403 for welding the collar a; The support plate 302b is provided with a moving groove 302b-1 that cooperates with the multiplying force cylinder 402.

[0045] The rest of the structure is the same as that of Example 2.

[0046] In summary, when the two sides of the ring a are butted, the auxiliary roller 303 is at the bottom of the ring a, and the end of the welding head 404 is facing the butt joint of the two sides of the ring a. At this time, the electric telescopic rod 403 is controlled to make the welding head 404 contact the position of the ring a to be welded, and the welding head 404 and the double-force cylinder 402 are started to drive the welding head 404 to weld along the direction of the butt joint of the two sides of the ring a. When the welding is completed, the connection between the second support block 301b and the support plate 302b is disconnected, and the processed ring a is taken out through the gap between the second support block 301b and the support plate 302b.
