Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically to a fully automatic grinding device for steel column-shaped heating pipes. Background Technology

[0002] Currently, steel column heating pipes are typically ground manually or semi-automatically after welding. Manual grinding is inefficient and costly, and because a person holds the workpiece to the belt sander, the quality of the ground workpiece is inconsistent. Existing semi-automatic grinding machines grind one end, then remove and grind the other end, followed by manual grinding of the area near the weld angle. Because the grinding is not done in one go, hard corners easily appear at the junction of the two grinding operations, affecting the appearance of the radiator and resulting in inconsistent quality. Therefore, based on actual usage, we have improved the above-mentioned existing technologies. Utility Model Content

[0033] Please see Figure 1-5 This utility model provides a technical solution: a fully automatic grinding device for steel columnar heating pipes. It should be noted that the steel columnar heating pipes... Figure 5 As shown, two pipes are welded to two plugs using a welding method, leaving weld beads at the weld joint. Traditional grinding methods are manual or semi-automatic, which are time-consuming and labor-intensive. Semi-automatic grinding requires grinding one end before grinding the other. The technical means provided in this application include:

[0034] The bottom frame 1 has support feet 4 connected to its four bottom corners, and a frame 2 is welded to the top of the bottom frame 1. Two sets of identical top slide rails 3 are connected parallel to the top of the frame 2, and bottom slide rails 101 are provided on the surface of the bottom frame 1. Figure 1 As shown, a trapezoidal frame 2 is welded to the top of the base frame 1 to ensure the stability of the overall device. Two sets of top slide rails 3 provide operating space for the grinding components. The grinding components here include the structural combination of the module base plate 7 and the grinding base plate 8 mentioned below. The operating space is that it can be clamped according to the length of the steel column heating pipe and realize fully automatic grinding operation.

[0035] Fixed support plate 5 is connected to the left end of top slide rail 3. Supporting vertical rods 501 are connected to the bottom of both sides of fixed support plate 5. The bottom of the supporting vertical rods 501 is connected to the top left side of bottom frame 1.

[0036] The movable support plate 6 is slidably connected to the top slide rail 3. The movable support plate 6 drives the components on it to slide horizontally on the top slide rail 3 to adapt to the length of the steel column heating pipe.

[0037] The module base plate 7 consists of two identical structures. The left module base plate 7 is connected to the top of the fixed support plate 5, and the right module base plate 7 is slidably connected to the top of the movable support plate 6. Each module base plate 7 has two identical grinding base plates 8 symmetrically connected to its top. The center of the fixed support plate 5 and the center of the top of the movable support plate 6 are symmetrically connected to two identical rotating shaft assemblies 702. Each rotating shaft assembly 702 is rotatably connected to a clamp 703 via a rotating shaft. By moving the movable support plate 6, the steel columnar heating pipe is placed on the two clamps 703, and then the grinding structure on the grinding base plate 8 performs the grinding operation on it.

[0038] Preferably, sliding vertical rods 601 are connected to the bottom of both sides of the movable support plate 6. The bottom of the sliding vertical rods 601 is connected to a movable wheel 603, and the movable wheel 603 is slidably connected to the bottom slide rail 101. A support slider 603 is welded to the bottom of the movable support plate 6, and the support slider 603 is slidably set on the top slide rail 3. The movable support plate 6 is provided with a limiting slider 604 that matches the top slide rail 3, and each set of limiting sliders 604 is threaded with a limiting bolt 605.

[0039] It should be noted that, please see Figure 2 and Figure 3 The movable wheel 603 slides on the bottom slide rail 101, driving the movable support plate 6 to move horizontally and clamp the heating pipe. At this time, the support slider 603 plays a good supporting role. After the position is fixed, the bottom of the limit bolt 605 is restricted to the top slide rail 3 by rotating the limit bolt 605, thereby fixing the movable support plate 6 and ensuring the stability of grinding.

[0040] Preferably, the bottom of the movable support plate 6 is connected to a hydraulic telescopic rod 606, and the telescopic end of the hydraulic telescopic rod 606 is connected to the outer end of the module base plate 7 which is slidably connected to the movable support plate 6.

[0041] It should be noted that, in order to ensure better stability of the heating pipe, after the movable support plate 6 is positioned, the bottom hydraulic telescopic rod 606 will work again to fine-tune the position of the movable support plate 6, ensuring the clamping stability of the two sets of clamps 703. At the same time, the hydraulic telescopic rod 606 is an existing structure, and its stroke has been adjusted. Its power is connected to an external energy source through a wire. It should also be emphasized that there is a pre-adjusted and set chassis around the grinding device to provide control and power for the circuit.

[0042] Preferably, the back of the rotating shaft assembly 702 located at the top of the fixed support plate 5 is connected to a rotating pulley via a shaft, and a transmission belt 9 is sleeved on the rotating pulley. The other end of the transmission belt 9 is sleeved on the power end of the rotating motor 10 via the rotating pulley, and the rotating motor 10 is mounted on the fixed support plate 5.

Here, the rotating motor 10 is a servo motor, and its power supply is connected to the external chassis via a wire.

[0043] Preferably, a linear guide rail 701 is provided on the top of the module base plate 7, and the grinding base plate 8 is slidably connected to the linear guide rail 701. Four sets of grinding base plates 8 move on the linear guide rail 701, and two sets of grinding base plates 8 can move in opposite directions to adjust the grinding force. It should be noted that the linear guide rail 701 is existing technology and will not be described in detail.

[0044] Preferably, the grinding base plate 8 is a T-shaped plate. A driving wheel 801 and a driven wheel 802 are connected to the top two sides of the grinding base plate 8, respectively. Two sets of identical driven wheels 803 are connected to the lower side wall of the grinding base plate 8 via connecting plates. The two connecting plates are elongated plates with mounting holes on the side wall of the grinding base plate 8. The two sets of connecting plates are mounted on the side wall of the grinding base plate 8 using fixing bolts. Furthermore, the mounting position of the two sets of connecting plates is adjustable, thus changing the angle between the grinding belt and the warming belt by adjusting the included angle of the driven wheels 803. The contact area of ​​the air pipe is adjusted to grind heating pipes of different specifications. The position of driven wheel 2 803 is adjusted by increasing the relative angle of the two sets of mounting plates, and driven wheel 2 803 is close to driven wheel 1 802. Drive wheel 801 is distributed on the outer side of each set of grinding base plates 8, and drive wheel 801 is sleeved on the power end of grinding motor 804. Grinding motor 804 is installed on the outer side wall of each set of grinding base plates 8. Grinding belts are sleeved on drive wheel 801, driven wheel 1 802 and the two sets of driven wheel 2 803.

[0045] It should be noted that you should refer to [link / reference]. Figure 1The diameter of the driving wheel 801 is larger than that of the driven wheel 802, and the diameter of the driven wheel 802 is larger than that of the driven wheel 803. Grinding belts are fitted onto the four sets of wheels, forming an irregular quadrilateral grinding system. The size of the grinding belts is one-third the size of the wheels (including but not limited to this size, as long as it is larger than the width of the weld bead), and the grinding surface of the belts is abrasive. The grinding motor 804 is connected to an external housing via wires. When the heating pipe is positioned, the grinding motor 804 is activated, and the four sets of wheels drive the grinding belts to rotate, grinding the weld bead of the clamped heating pipe. The motors and hydraulic components used in the device are all connected to the external housing via wires, and their strokes are pre-set, enabling fully automatic grinding operation.

[0046] It should be noted that the electrical components of this utility model have already combed the wire harness during operation, so there will be no problem of wire harness tangling.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
