Description

Technical Field

[0001] This utility model relates to the field of workpiece grinding technology, specifically a tooling structure for edge grinding. Background Technology

[0002] Metal workpieces, such as guillotines or guide plates, often require surface angle treatment for use in enterprise production. This facilitates installation on existing equipment and also makes cutting and other related processes easier. For example, CN217451860U describes a guide plate structure for a steel rolling straightening machine, which requires tilting one side of the machined surface.

[0003] Current cutting edge machining is handled by machining centers. Regardless of whether the machining center is three-axis, four-axis, or five-axis, the differences in XYZ and rotational directions mean that for inclined surfaces, shims are still needed to ensure the angle and length accuracy of the cutting edge machining.

[0004] For certain workpieces, the end corners need to be ground to create an inclined grinding surface, which is normally inclined. This requires specific angle and dimensional control, as well as a high degree of surface roughness or finish. Therefore, existing technologies lack a one-piece molded backing plate to support the grinding surface.

[0005] To address these issues, we provide a tooling structure for edge grinding. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tooling structure for cutting edge grinding to solve the technical problem of supporting the grinding surface to change from inclined to horizontal.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A tooling structure for edge grinding includes a workpiece to be processed, and the workpiece has mounting holes.

[0009] Also includes:

[0010] The fixture plate is installed on the bottom of the workpiece and has a boss edge that abuts against the workpiece. The fixture plate includes a working surface a and a working surface b. Working surface a is the contact surface that abuts against the workpiece, and working surface b is the bottom surface that abuts against the worktable. Working surfaces a and b are parallel. When the fixture plate is installed on the worktable, working surface a is inclined upward and the angle between it and the horizontal is the same as the angle between the grinding surface to be processed and the horizontal line.

[0011] Fixtures are suitable for detachably and securely mounting workpieces onto a tooling plate.

[0012] The hydrostatic grinding head spindle and grinding wheel are mounted on the workpiece and connected at the end to the grinding wheel; the grinding wheel is suitable for grinding the workpiece.

[0013] In a further technical solution, the fixture includes a pressure plate and a positioning bolt, wherein the outer diameter of the pressure plate is larger than the inner diameter of the mounting hole; a positioning screw hole is provided on the tooling plate; the positioning bolt is adapted to pass through the pressure plate from top to bottom and be threadedly connected to the positioning screw hole.

[0014] The inner diameter of the mounting hole is not less than the outer diameter of the bolt body of the positioning bolt.

[0015] In a further technical solution, the mounting holes are provided in multiple sets and are arranged in parallel along the same axis; the positioning screw holes are provided in two sets.

[0016] The tooling plate is equipped with two sets, and the two sets of bosses face each other and abut against each other;

[0017] When the tooling plate is installed on the workbench, the working surface b placed on the workbench is horizontal.

[0018] In a further technical solution, the top corners of the horizontal ends of the workpieces mounted on the two sets of tooling plates are the positions to be processed, and are located on the opposite sides of the two sets of workpieces.

[0019] The end face of the workpiece is rectangular, and the opposite sides are arc-shaped; the horizontal length of the workpiece is not greater than the horizontal length of the tooling plate.

[0020] In a further technical solution, the horizontal cross-section of the tooling plate is "L" shaped, with the top adjacent edges set vertically, the bottom side near the boss edge having an obtuse angle, and the side away from the boss edge having an acute angle.

[0021] In a further technical solution, the obtuse angle of the horizontal cross-section of the tooling plate is 91.27° and the acute angle is 88.73°;

[0022] The horizontal length of the surface to be ground is 45mm and the height is 1mm.

[0023] In a further technical solution, when the tooling plate is not installed, the working surface b is inclined downwards and the top working surface a is horizontal; when the tooling plate is installed on the worktable, the worktable is horizontal, the working surface b is horizontal, and the working surface a is inclined upwards.

[0024] Compared with existing technologies, it has the following advantages:

[0025] This invention achieves a change in the grinding surface of the workpiece from inclined to horizontal by setting an inclined tooling plate, allowing the grinding wheel of the grinding machine or machining center to directly perform up-and-down grinding, making grinding more convenient. Secondly, the symmetrical installation of two sets of workpieces and tooling plates enables rapid movement for processing. The bottom of the tooling plate is inclined, and its one-piece forming ensures the horizontal grinding surface of the cutting edge, facilitating processing; 2. The surface finish of the cutting edge reaches 0.4, and the processing dimensions meet the requirements. This invention uses a pressure plate to fix the bolt head of the positioning bolt. The middle of the bolt body passes through the workpiece, and the bottom of the bolt body is threaded to the tooling plate, achieving a tight connection. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1

[0042] Please see Figure 1-3 This utility model provides a technical solution:

[0043] A tooling structure for edge grinding includes a workpiece 1 to be processed, and a mounting hole 2 is provided on the workpiece 1.

[0044] Also includes:

[0045] Tooling plate 3 is installed on the bottom of workpiece 1, and a boss edge 4 is provided on tooling plate 3, which abuts against workpiece 1. Tooling plate 3 includes working surface a and working surface b. Working surface a is the contact surface abutting against workpiece 1, and working surface b is the bottom surface abutting against worktable surface 100. Working surfaces a and b are parallel. When tooling plate 3 is installed on worktable surface 100, working surface a is inclined upward, and the angle between it and the horizontal is the same as the angle between the grinding surface 10 to be processed and the horizontal line. Working surfaces a and b are referenced. Figure 2 The front and back sides are shown. The worktable 100 is the worktable of the equipment, which is generally set to a standard horizontal position. The equipment is such as a machining center or a grinding machine.

[0046] The fixture is suitable for detachably fixing the workpiece 1 onto the tooling plate 3;

[0047] The hydrostatic grinding head spindle 5 and grinding wheel 6 are mounted on the workpiece 1, with its end connected to the grinding wheel 6. The hydrostatic grinding head spindle 5 drives the grinding wheel 6 to rotate, and the grinding wheel 6 is suitable for grinding the workpiece 1. The hydrostatic grinding head spindle is a high-precision machine tool component designed based on hydrostatic bearing technology. It is mainly used in precision machining equipment such as grinding machines to bear the high-speed rotational motion of the workpiece or cutting tool. Its core feature is that a stable lubricating oil film is formed between the spindle and the bearing through external pressure oil (or gas), allowing the spindle to operate in a suspended state, thereby achieving high-precision, high-rigidity, and low-friction machining performance. A grinding wheel of appropriate size is selected for grinding the workpiece.

[0048] The mounting holes 2 are provided in multiple sets and are arranged in parallel along the same axis; the positioning screw holes 9 are provided in two sets; the tooling plate 3 is provided in two sets, and the two sets of boss edges 4 face each other and abut against each other;

[0049] like Figure 7 and 9 As shown, when the tooling plate 3 is installed on the worktable 100, the working surface b placed on the worktable 100 is horizontal. Figure 9 There are two tooling plate configurations. The left side, when not in use, represents the design dimensions and uses a bottom tilt compensation setting. During actual installation, it is placed on a horizontal work platform, which corresponds to the working position on the right side. The difference lies in the bottom working surface b of the left tooling plate, which is tilted downwards while the working surface a is horizontal; the right tooling plate has working surface b horizontally set and working surface a tilted upwards.

[0050] The top corners of the horizontal ends of the workpieces 1 mounted on the two sets of tooling plates 3 are the positions to be processed, and are located on the opposite sides of the two sets of workpieces 1.

[0051] The end face of the workpiece 1 is rectangular, and the opposite sides are arc-shaped; the horizontal length of the workpiece 1 is not greater than the horizontal length of the tooling plate 3.

[0052] Specifically, such as Figure 7 and 8 As shown, the horizontal cross-section of the tooling plate 3 is L-shaped, with adjacent top edges perpendicular to each other. The bottom edge near the boss edge 4 has an obtuse angle, and the edge away from the boss edge 4 has an acute angle. The obtuse angle of the horizontal cross-section of the tooling plate 3 is 91.27°, and the acute angle is 88.73°. The horizontal length of the grinding surface 10 to be processed is 45mm, and the height is 1mm. The angle between the obtuse angle and the horizontal line is 1.27°, while... Figure 4 and Figure 6 The triangular grinding surface is right-angled, and its projection in the horizontal direction has a length of 45mm and a height of 1mm. The angle is arctan(1 / 45) = 1.27°. Therefore, the working surface a is inclined upward, and the angle between it and the horizontal is the same as the angle between the grinding surface 10 to be processed and the horizontal line.

[0053] like Figure 9 As shown, when the tooling plate 3 is not installed, the working surface b is inclined downwards and the top working surface a is horizontal; when the tooling plate 3 is installed on the worktable 100, the worktable 100 is horizontal, the working surface b is horizontal, and the working surface a is inclined upwards.

[0054] This invention achieves the change of the workpiece's grinding surface from inclined to horizontal by setting an inclined fixture plate, allowing the grinding wheel of the grinding machine or machining center to directly perform up-and-down grinding, making grinding more convenient. Secondly, the symmetrical installation of two sets of workpieces and fixture plates enables rapid movement for processing. The bottom of the fixture plate is inclined, and its one-time forming ensures the horizontal grinding surface of the cutting edge, facilitating processing; 2. The surface finish of the cutting edge reaches 0.4, and the processing dimensions meet the requirements.

[0055] Example 2

[0056] like Figure 10-12 As shown, this is another embodiment of the present invention, based on embodiment 1.

[0057] The fixture includes a pressure plate 7 and a positioning bolt 8. The outer diameter of the pressure plate 7 is larger than the inner diameter of the mounting hole 2. A positioning screw hole 9 is provided on the tooling plate 3. The positioning bolt 8 is adapted to pass through the pressure plate 7 from top to bottom and be threadedly connected to the positioning screw hole 9.

[0058] The inner diameter of the mounting hole 2 is not less than the outer diameter of the bolt body of the positioning bolt 8.

[0059] This invention uses a pressure plate to fix the bolt head of the positioning bolt, the middle of the bolt body passes through the workpiece, and the bottom of the bolt body is threaded to the tooling plate to achieve a fast connection.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
