Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, and in particular to a pipe fitting slope cutting positioning device. Background Technology

[0002] Cutting building materials such as pipes and decorative strips generally includes flat cutting or bevel cutting. Bevel cutting aims to make the beveled edges of two materials mirror-symmetrical, achieving a snug fit for decorative arrangements, welding, or thermofusion connections. However, some pipes or decorative pieces require flexible adjustments based on terrain during connection; direct connections or 90-degree splicing cannot perfectly conform to the terrain. Specifically, when wall corners are acute or obtuse, achieving a tight fit is particularly difficult. In other words, when the outer diameters of the materials are the same, the angles of the two beveled surfaces to be joined or spliced ​​must be completely identical to ensure perfect correspondence and a neat connection; or, when used for welding or thermofusion connections, to ensure the strength and sealing of the joint.

[0003] The most common piece of equipment on construction sites is the cutting machine, but most cutting machines only have the function of cutting flat surfaces or 45-degree slopes. They cannot accurately position for other angles, which means that in special situations, it is impossible to cut two symmetrical slopes. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a pipe slope cutting positioning device with a simple structure, which is assembled based on a cutting machine and mounted on the cutting machine table, and can position the pipe cutting angle from multiple angles.

[0005] The equipment includes a fastener for mounting on the table of the cutting equipment;

[0006] An angle positioning plate is fixedly installed on the fixing component;

[0007] A support plate is rotatably mounted on the angle positioning disk, and a positioning component is provided between the support plate and the angle positioning disk.

[0008] The support plate is equipped with a pipe clamping device.

[0009] The effect achieved is that the fixing component, together with the angle positioning plate, is fixed on the table of the cutting equipment; by rotating the support plate and locking it with the positioning component, the pipe clamping device on it forms a fixed angle with the cutting direction, that is, the pipe forms a fixed angle with the cutting direction; under this condition, the cutting unit of the cutting equipment can cut the pipe into the target bevel according to the orientation of the support plate.

[0010] The beneficial effects of this utility model are: it solves the problem of the lack of multi-angle positioning cutting assistance in existing cutting equipment when cutting slopes; by adjusting the orientation of the support plate and the angle positioning plate, the workpiece can be cut at multiple angles on the slope, thereby achieving a tight fit between the two cutting slopes. In particular, the equipment has a simple structure, low cost, and low maintenance cost, and can be assembled onto existing cutting machines as an auxiliary component, achieving low-cost modification of the cutting machine.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a pipe fitting slope cutting positioning device, which includes a fixing component for mounting on the table of the cutting equipment.

[0021] An angle positioning disc 3 is fixedly installed on the fixing component;

[0022] A support plate 6 is rotatably mounted on the angle positioning disk 3, and a positioning component 4 is provided between the support plate 6 and the angle positioning disk 3.

[0023] The support plate 6 is provided with a pipe clamping device 5.

[0024] The effect achieved is that the fixing component, together with the angle positioning plate 3, is fixed on the table of the cutting equipment; the support plate 6 is rotated and locked by the positioning component 4, and the pipe clamping device 5 on it forms a fixed angle with the cutting direction, that is, the pipe forms a fixed angle with the cutting direction; under this condition, the cutting unit of the cutting equipment is activated, and the pipe is cut into the target bevel according to the orientation of the support plate 6.

[0025] In Example 1, the fixing component includes a square bar connecting rod 1, with limiting plates 2 fixedly installed at both ends of the square bar connecting rod 1, and a positioning screw screwed onto one of the limiting plates 2.

[0026] In other words, the square connecting rod 1, together with its limiting plate 2, is snapped onto the worktable of the cutting equipment and locked in a hard limiting manner using its positioning screw; thus, a stable connection between the entire equipment and the cutting equipment can be achieved.

[0027] Furthermore, an anti-slip pad is provided on the inner surface of one of the limiting plates 2; a positioning screw is provided on the other limiting plate 2; and the end of the positioning screw is provided with an internal hexagonal groove.

[0028] The effect achieved is to improve assembly stability and ease of assembly.

Figure 5 The square bar connecting rod 1 is provided with a slide rail, the angle positioning disk 3 is slidably disposed on the square bar connecting rod 1, and a positioning bolt is provided between the angle positioning disk 3 and the square bar connecting rod 1.

[0030] Preferably, the square bar connecting rod 1 has protruding sliding strips on both sides, which together with the square bar connecting rod 1 form a T-shaped sliding track at the top;

[0031] The angle positioning disk 3 has a slider integrally provided below it, corresponding to the slide rail, and is slidably connected to the square bar connecting rod 1.

[0032] The effect achieved is that the angle positioning disk 3 and the part above it can slide on the square bar connecting rod 1, thereby adapting to different types of cutting equipment and corresponding cutting action unit positions.

[0033] Example 3, refer to the accompanying drawings in the specification. Figure 3 or Figure 4 The angle positioning disk 3 is a circular disk, and scale markings are provided on the circular angle positioning disk 3.

[0034] The support plate 6 is a disc, and the support plate 6 is centrally mounted on the angle positioning disc 3;

[0035] A pointer 7 is provided on the side of the support plate 6.

[0036] Preferably, the scale markings are based on the bevel angle of the pipe after cutting. The bevel angle refers to the angle between the cut bevel and the bottom surface of the pipe. For example, in the case of vertical cutting, pointer 7 points to 90°.

[0037] The effect achieved is that when the support plate 6 is rotated, the angle of the cutting slope can be read directly according to the pointer 7.

[0038] Preferably, the support plate 6 and the angle positioning disk 3 are connected by a male-female joint for rotation, or by a bearing for rotation; the support plate 6 is fitted to the top of the angle positioning disk 3.

[0045] A positioning frame is provided across one of the pipe supports, and a clamping screw 51 is screwed onto the top of the positioning frame. A pipe clamp 52 is rotatably provided on the bottom surface of the clamping screw 51.

[0046] Furthermore, the pipe support includes a base, which is fixedly connected to the support plate 6, and a pipe bracket 53 is provided on the base. The pipe bracket 53 is a concave arc-shaped bracket.

[0047] The pipe clamp 52 is a concave arc-shaped clamp.

[0048] The effect achieved is that the basic function of the double pipe support is to raise the cutting part higher than the support plate 6, leaving a gap for the cutting tool; its setting can ensure the stability of the pipe cutting section, and the arc-shaped bracket can help to fix the round pipe equipment in the center.

[0049] Preferably, the clamping screw 51 is provided with a rotating arm.

[0050] In use, the fixing component, together with the angle positioning disk 3, is fixed to the table of the cutting equipment; according to the position of the cutting unit of the cutting equipment, the angle positioning disk 3 and the components on it are slid so that the center of the angle positioning disk 3 is basically placed below the cutting unit;

[0051] Depending on the cutting angle, rotate the support plate 6 and lock it using the positioning component 4.
