Description

Technical Field

[0001] The utility model belongs to the technical field of flange roller assembly, and in particular relates to a flange roller assembly jig. Background Art

[0002] A roller refers to a cylindrical object that can rotate in a machine. A power source such as a motor is often used to drive the roller to drive other materials forward, or to use the pressure generated by the roller to process the material. When the roller is in use, a flange is installed at the end of the roller to achieve the installation of the roller.

[0003] Currently, when a roller needs to be welded with a flange retaining ring, since the inner diameter of the flange retaining ring is larger than the outer diameter of the roller, the position of the flange retaining ring cannot be fixed during assembly and the parallelism of the flange retaining rings on both sides and the concentricity of the flange retaining ring and the roller cannot be guaranteed. Currently, flange-containing products all require manual measurement of the flange retaining ring welding position, and then spot welding with a welding gun to fix the flange retaining ring, and then full welding with gas shielded welding. The production process is relatively complicated, the operation is difficult, and the production efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide a flange roller assembly jig to solve the problem that when a roller needs to be welded with a flange retaining ring as mentioned in the above background technology, since the inner diameter of the flange retaining ring is larger than the outer diameter of the roller, the position of the flange retaining ring cannot be fixed during assembly and the parallelism of the flange retaining rings on both sides and the concentricity of the flange retaining ring and the roller cannot be guaranteed. At present, flange-containing products all manually measure the welding position of the flange retaining ring, and then use a welding gun to spot weld to fix the flange retaining ring, and then perform gas shielded welding to fully weld, resulting in a relatively complicated production process, high operating difficulty and low production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange roller assembly jig, comprising a supporting bracket, a fixed base plate is fixedly installed on the upper surface of the supporting bracket, a fixed baffle, a fixed tooth plate and four mounting blocks are fixedly installed on the upper surface of the fixed base plate, an optical axis guide rail is fixedly installed between two mounting blocks on the same side, two tooling base plates are slidably arranged above the fixed base plate, a plurality of box-type linear sliders are fixedly installed on the lower surface of the tooling base plate, the box-type linear sliders are slidably installed on the outer surface of the optical axis guide rail at the same side position, a tooling frame is fixedly installed on the upper surface of the tooling base plate, two tooling clamps are arranged in the tooling frame, a positioning plate is fixedly installed on the side of the tooling base plate, a movable tooth plate is movably arranged below the positioning plate, and the movable tooth plate is meshed with the fixed tooth plate for use.

[0006] The above scheme is adopted, by setting a fixed baffle, a movable baffle and two tooling bottom plates for use in combination, the fixed baffle is fixed, and the movable baffle is position-adjusted by a one-way screw, thereby realizing the clamping of both ends of the roller, and the two tooling bottom plates can be position-adjusted, and flange rollers of different lengths can be welded, ensuring the concentricity of the flange retaining ring and the roller and the adjustable welding position of the flange retaining ring, while reducing the manual installation and measurement time, different pipe diameters can be achieved by rotating the two-way screw to realize the movement of the two tooling clamping plates in the tooling frame, thereby achieving flange rollers of different pipe diameters and improving universality, and by setting a support cylinder for use in combination with the movable baffle, one end of the support cylinder is inserted into the roller, and the rotation of the rotating shaft drives the elliptical disk to rotate, and then drives the matching plate to drive the tightening plate to move, so that the tightening plate is pressed against the inner wall of the roller, further improving the fixing and clamping effect of the roller, avoiding loosening, falling and tilting, ensuring that the roller is in a good horizontal state for welding, and further improving the welding operation accuracy.

[0007] As a preferred embodiment, sliding blocks are fixedly installed on both ends of the tooling pallet, a slideway for the sliding block to pass through is opened on the side of the tooling frame, two fixed blocks are fixedly installed on the side of the tooling frame, a bidirectional screw is rotatably installed between the two fixed blocks, a knob is fixedly installed at one end of the bidirectional screw, and two sliding blocks on the same side of the bidirectional screw are respectively threadedly installed on the two sections of the threaded outer surface of the bidirectional screw.

When the knob is rotated, the bidirectional screw is driven to rotate, and then the sliding block is driven to drive the tooling clamp to move, thereby achieving a fixed clamping effect on the flange retaining ring.

[0009] As a preferred embodiment, a fixed guide rod is fixedly installed on the inner wall of the slideway on the tooling frame, and the sliding block is slidably installed on the outer surface of the fixed guide rod at the same side position.

[0010] By adopting the above scheme, the sliding block can be supported and guided by the setting of the fixed guide rod, so that the sliding block has better stability when driving the tooling pallet to move, and is less likely to tilt and shake.

[0011] As a preferred embodiment, a positioning slide rod is slidably installed on the positioning plate, an operating plate is fixedly installed on the top end of the positioning slide rod, the bottom end of the positioning slide rod is fixedly connected to the movable tooth plate, and a spring is fixedly installed between the movable tooth plate and the positioning plate.

[0012] By adopting the above scheme, the positioning slide bar is used to realize the vertical movement of the movable tooth plate up and down. When the operating panel drives the positioning slide bar to move upward, the positioning slide bar will drive the movable tooth plate to move away from the fixed tooth plate. At this time, the spring 1 is deformed and the tooling base plate is unlocked. The elastic force of the spring 1 can be used to drive the movable tooth plate to move downward quickly and engage with the fixed tooth plate, thereby achieving the fixed clamping of the tooling base plate.

[0013] As a preferred embodiment, a support block is fixedly mounted on the upper surface of the fixed base plate, a one-way screw is threadedly mounted on the support block, a handle is fixedly mounted on one end of the one-way screw, and a movable baffle is rotatably mounted on the other end of the one-way screw.

[0017] As a preferred embodiment, the fixed baffle and the movable baffle are both fixedly installed with a support tube, a rotating shaft is rotatably installed in the support tube, one end of the rotating shaft extends out of the support tube and is fixedly installed with a rotating handle, and the other end of the rotating shaft is fixedly installed with an elliptical disk, and the outer surface of the elliptical disk is matched with a plurality of matching plates, and the matching plates slide through and extend out of the support tube and are fixedly installed with a tightening plate.

[0018] By adopting the above scheme, the rotating handle is used to rotate the rotating shaft, and the rotating shaft drives the elliptical disk to rotate, thereby driving the matching plate to drive the tightening plate to move, and the tightening plate is extended out of the supporting tube to achieve the fixing and tightening effect on the inner wall of the roller.

[0019] As a preferred implementation, a squeeze bolt is threadedly mounted on the turning handle, and the tail end of the squeeze bolt is arranged to fit the side surface of the support tube.

[0020] By adopting the above scheme, when the squeezing bolt is screwed off the turning handle, the turning handle is unlocked and can be rotated. After being rotated to a suitable position, the squeezing bolt is screwed on to achieve position locking of the turning handle.

[0021] As a preferred embodiment, a support guide rod is fixedly installed on the inner wall of the support tube, a spring 2 is sleeved on the outside of the support guide rod, a limiting slider is fixedly installed on the side of the matching plate, the limiting slider is slidably installed on the outer surface of the support guide rod, and the two ends of the spring 2 are respectively fixedly connected to the inner wall of the support tube and the surface of the limiting slider.

[0022] By adopting the above scheme, the support guide rod is used in conjunction with the limit slider, which can support the movement of the matching plate, so that the matching plate moves smoothly and is not prone to shaking. The setting of spring 2 can have a reset effect. When the elliptical disk rotates to drive the matching plate to drive the tightening plate to move outward, spring 2 will be squeezed and deformed. Therefore, when the elliptical disk rotates in the opposite direction to reset, the elastic force of spring 2 will drive the matching plate to drive the tightening plate to quickly retract and reset, thereby improving the convenience of operation.

[0023] As a preferred embodiment, a rotation groove is formed on one side of the matching plate facing the elliptical disk, and a roller is rotatably mounted on the inner wall of the rotation groove, and the wheel of the roller is rollingly arranged on the outer surface of the elliptical disk.

[0024] By adopting the above scheme, the setting of the rotating groove is used in conjunction with the roller, so that the matching plate and the elliptical disk can be used in a rolling manner through the roller, and the friction between the structures is greatly reduced.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] The flange roller assembly jig is used in conjunction with a fixed baffle, a movable baffle and two tooling bottom plates. The fixed baffle is fixed, and the movable baffle is adjusted in position by a one-way screw, thereby achieving clamping of both ends of the roller. Both tooling bottom plates can be adjusted in position, and flange rollers of different lengths can be welded to ensure the concentricity of the flange retaining ring and the roller and the adjustable welding position of the flange retaining ring, while reducing the manual installation and measurement time. Different pipe diameters can be achieved by rotating the two tooling clamping plates in the tooling frame, thereby achieving flange roller welding of different pipe diameters, thereby improving universality.

[0027] The flange roller assembly fixture is used by setting a support tube in conjunction with a movable baffle. One end of the support tube is inserted into the roller, and the rotation of the rotating shaft drives the elliptical disk to rotate, and then drives the matching plate to drive the tightening plate to move, so that the tightening plate is pressed against the inner wall of the roller, further improving the fixing and clamping effect of the roller, avoiding loosening, falling and tilting, ensuring that the roller is in a good horizontal state for welding, and further improving the accuracy of the welding operation.
