Abstract
Description
Technical Field
[0001] This application relates to the field of grinding machine processing technology, and more specifically, to a processing fixture for a grinding machine. Background Technology
[0002] In the field of machining, grinding machines are widely used in the processing of high-precision parts, especially in the grinding of precision components (such as shafts, discs, and molds). Traditional grinding machine fixtures are typically designed with a single-workpiece clamping structure, meaning that only one workpiece can be clamped and processed at a time. The main problems with single-workpiece machining fixtures include: low processing efficiency: only one workpiece can be processed at a time, and for mass production tasks, frequent loading and unloading of workpieces is required, resulting in low production efficiency.
[0003] Therefore, a machining fixture for a grinding machine that improves machining efficiency is provided. Utility Model Content

[0030] Example 1:
[0031] Reference Figure 1-2A machining fixture for a grinding machine, used to fix a workpiece 103, includes: a mounting plate 101 and a fixing member for fixing the workpiece 103. The mounting plate 101 includes multiple mounting grooves 102, which are equidistantly distributed along the circumference of the mounting plate 101. Each mounting groove 102 includes a first positioning surface 102a, a second positioning surface 102b, and a third positioning surface 102c. The first positioning surface 102a is used for positioning the workpiece 103 in the length direction, the second positioning surface 102b is used for positioning the workpiece 103 in the width direction, and the third positioning surface 102c is used for positioning the workpiece 103 in the height direction. Two first positioning surfaces 102a are provided, one of which abuts against one end of the workpiece 103, and the other abuts against the other end of the workpiece 103. The mounting groove 102 also includes an arc 102d for smooth transition between the first positioning surface 102a and the second positioning surface 102b.
[0032] A fastener, a first bolt 104, is used to fix the workpiece 103. The first bolt 104 is threadedly connected to the mounting plate 101. The mounting plate 101 has a first threaded hole 101a, and the threaded end of the first bolt 104 is threadedly connected to the first threaded hole 101a. Multiple first threaded holes 101a are provided, equidistantly distributed along the circumference of the mounting plate 101. The workpiece 103 includes a countersunk hole 103a, which serves as the nut for the first bolt 104. The workpiece 103 is placed in the mounting groove 102, so that it abuts against the first positioning surface 102a, the second positioning surface 102b, and the third positioning surface 102c respectively. Then, the workpiece 103 is fixed by the first bolt 104, with the nut of the first bolt 104 located within the countersunk hole 103a. The machined surface 103b of the workpiece 103 is then ground using a grinding machine. Compared to traditional single-processing, this reduces the time required for frequent loading and unloading of the workpiece 103, thereby improving processing efficiency.
[0033] Example 2:
[0034] Reference Figure 3-4 The difference from Embodiment 1 lies in the fastener. Since some workpieces 103 lack countersunk holes 103a, they cannot be directly fixed with bolts. Therefore, the fastener is optimized. The fastener includes: a fixing ring 105, a pressure plate 106, a guide block 107, a transmission block 108, and a second bolt 109. The fixing ring 105 is fixedly connected to the mounting plate 101. The transmission block 108 is radially slidably connected to the fixing ring 105. Specifically, the fixing ring 105 has a first groove 105a extending radially from the fixing ring 105. The transmission block 108 is partially located within the first groove 105a and moves along the first groove 105a. The guide block 107 is fixedly connected to the fixing ring 105.
[0035] The guide block 107 has a U-shaped structure. The pressure plate 106 is horizontally slidably connected to the guide block 107. Specifically, the guide block 107 has a second groove 107a extending along the length of the guide block 107. The pressure plate 106 is partially located within the second groove 107a and moves along the second groove 107a. The second bolt 109 is threadedly connected to the retaining ring 105. The pressure plate 106 includes a first inclined surface 106a, and the transmission block 108 includes a second inclined surface 108a. The pressure plate 106 fixes the workpiece 103 through the first inclined surface 106a and the second inclined surface 108a. Tighten the second nut with an Allen wrench to make the first inclined surface 106a of the pressure plate 106 abut against the second inclined surface 108a of the transmission block 108. The transmission block 108 moves along the first sliding groove 105a. Therefore, the pressure plate 106 will cause the transmission block 108 to press against one end of the workpiece 103, thereby fixing the workpiece 103. For workpieces 103 without countersunk holes 103a, they can be fixed by pressing against one side of the workpiece 103.
