Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, specifically a grinding device for furnace body joints. Background Technology

[0002] Larger furnace bodies are typically welded together in two sections during manufacturing. Before welding, the joint between the two sections needs to be ground and polished to ensure a smooth finish after welding.

[0003] Patent CN206898925U proposes a weld seam grinding device, which brings the groove of grinding wheel roller I or the notch of grinding wheel roller II into contact with the weld seam. Grinding wheel roller I is used for flat welds, and grinding wheel roller II is used for fillet welds. The motor II is started to drive grinding wheel roller I or grinding wheel roller II to rotate. At the same time, the motor I drives the lead screw to rotate, thereby moving the nut installed on the lead screw forward. The nut drives the frame plate and motor II to move forward, ultimately making grinding wheel roller I or grinding wheel roller II rotate and move forward at the same time, thus realizing continuous grinding of the weld seam.

[0004] The shortcomings of the above solution are: when processing and grinding furnace bodies with uncertain dimensions, it is inconvenient to adjust the position of the grinding wheel, and the grinding of the furnace body joints is done before welding. Since the two ends of the furnace body are separate units, additional clamping equipment is required for fixation, which is inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a furnace body joint grinding device to solve the problems mentioned in the background. This invention has a novel structure, with a clamping component and a grinding component working together to clamp and fix the two furnace body parts after they are joined. The grinding component performs rotary grinding on the joint area. This process avoids interference from the upper clamping plate with the movement of the grinding component, improves efficiency, and maintains the stability of the furnace body during grinding. It is suitable for use with furnace bodies of various sizes.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a furnace body seam grinding device, including a base, a clamping assembly on the surface of the base, the clamping assembly including a sliding groove, the sliding groove being opened on the surface of the base, and two movable frames slidably connected within the sliding groove, a lower clamping plate fixed to the top of the movable frame, an upper clamping plate on the top of the lower clamping plate, a grinding assembly on one side of the base, the grinding assembly including a rotating ring, the rotating ring being rotatably mounted on the outer ring of the base, and a sliding frame fixed to one side of the rotating ring, a toothed plate being slidably inserted inside the sliding frame, a vertical frame fixed to the outer end of the toothed plate, and a horizontal frame slidably mounted on the surface of the vertical frame, a grinding wheel rotatably mounted on the outer side of the horizontal frame, a first motor fixed to the top of the grinding wheel on the horizontal frame, and the output end of the first motor being fixedly connected to the grinding wheel, a ring on the top of the horizontal frame, two vertical plates symmetrically arranged on the upper surface of the ring, and an electric push rod fixed to the surface of the vertical plate, the extended end of the electric push rod being fixedly connected to the upper clamping plate.

[0007] Furthermore, the grinding assembly also includes a gear ring, a gear ring is fixed to the bottom of the rotating ring, a fourth motor is fixed to one side of the base, and a second gear is fixed to the output end of the fourth motor, the output end of the second gear meshing with the gear ring.

[0008] Furthermore, a third motor is fixed to one side of the sliding frame, and a first gear is fixed to the output end of the third motor, the first gear being meshed with the gear plate.

[0009] Furthermore, a vertical screw is rotatably mounted inside the vertical frame via bearings, and a horizontal frame is threaded onto the surface of the vertical screw. A pulley is fixed at the bottom of the vertical frame, and a second motor is fixed at the top of the vertical frame, with the output end of the second motor fixedly connected to the vertical screw.

[0010] Furthermore, the clamping assembly also includes a bidirectional screw, which is rotatably mounted inside the slide groove via a built-in motor and bearings, and the bottom of the moving frame is threaded onto the surface of the bidirectional screw.

[0011] Furthermore, a protruding strip is fixed to the top of the crossbar, and a slot is provided on one side of the ring corresponding to the protruding strip, with the protruding strip slidably inserted into the slot. A telescopic rod is fixed to the other end of the ring, and the bottom of the telescopic rod is fixedly connected to the rotating ring.

[0012] Furthermore, the top of the ring is provided with an annular groove, and the bottom of the vertical plate slides along the inside of the annular groove.

[0013] Furthermore, both sides of the upper and lower clamping plates are fixed with straps.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a second motor to drive a vertical screw to rotate, adjusting the height of the cross frame and the grinding wheel. A third motor drives a first gear to rotate and mesh with a toothed plate, adjusting the horizontal position of the grinding wheel. This adjustment is made for different furnace body seam positions. The first motor drives the grinding wheel to rotate and grind the seam. A fourth motor drives a second gear to mesh with a toothed ring, causing the ring to rotate, making the grinding assembly move in a circular motion around the furnace body, thus improving grinding efficiency.

[0016] 2. This utility model, through the connection of the ring, allows the height of the upper clamping plate to be adjusted synchronously during the initial adjustment of the grinding component position, ensuring that the upper clamping plate is always located at the top of the grinding wheel. The horizontal movement of the crossbeam can slide along the groove of the ring. The lifting and lowering movement of the ring is maintained in connection with the rotating ring through the telescopic rod. Furthermore, when the ring rotates, the vertical plate slides along the annular groove due to the clamping of the upper clamping plate and the furnace body. The furnace body is further wrapped and fixed by the straps on both sides of the upper and lower clamping plates, improving stability.

[0017] 3. This utility model uses two movable frames and a bidirectional screw to slide along the slide groove, which drives the lower clamping plate to clamp the lower furnace body, stacking the upper furnace body with the lower furnace body, and the electric push rod drives the upper clamping plate to clamp and fix the upper furnace body.

[0018] 4. Compared with the prior art, the clamping component and the grinding component work together to clamp and fix the two furnace body parts after they are joined. The grinding component performs rotational grinding at the joint. This process can avoid the upper clamping plate interfering with the movement of the grinding component, improve efficiency, maintain the stability of the furnace body during grinding, and is suitable for use with furnace bodies of various sizes.
