Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a special workpiece locator for a machining center. Background Art

[0002] Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. In the processing of CNC machine tools, especially milling machines, the workpiece needs to be positioned before processing.

[0003] In machining centers, precision machining usually requires the workpiece to maintain a stable position and posture during the machining process. The function of the fixture is to ensure that the workpiece is fixed and stable on the worktable of the machining center for precise machining. The fixture adjusts the position of the locking plate and uses the locking of the limit bolt and the movable bolt to achieve the position adjustment and stable fixation of the workpiece.

[0004] The existing fixtures have a complex structure and high cost, and have certain limitations in use. They cannot perform multi-point positioning and do not have certain assembly adjustments, so they cannot be widely used on most machine tools. Most fixtures are fixed with only one bolt, and are prone to loosening after long-term use. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a special workpiece locator for a machining center, comprising a fixed base plate 1, a fixing bolt 2 is slidably connected inside the fixed base plate 1, a T-block 3 is threadedly connected to the outer wall of the fixing bolt 2, a slide seat 4 is rotatably connected to the outer wall of the fixing bolt 2, a first top plate 5 is fixedly connected to the outer wall of the fixing bolt 2, the outer wall of the first top plate 5 is slidably connected to the inside of the slide seat 4, a first spring 6 is sleeved on the outer wall of the fixing bolt 2, a fixed seat 7 is fixedly connected to the outer wall of the fixed base plate 1, a slide rod 8 is slidably connected to the inside of the fixed seat 7, the outer wall of the slide rod 8 is fixedly connected to the second top plate 9, the outer wall bottom of the slide rod 8 is fixedly connected to the support plate 11, the outer wall of the slide rod 8 is sleeved with a second spring 10, the outer wall of the fixed base plate 1 is slidably connected to the locking plate 12, and a limiting component is arranged inside the locking plate 12;

[0023] Specifically, the fixing bolt 2 is rotated through the T-block 3 to achieve the clamping of the fixed base plate 1 and the T-block 3 on the workbench. As the fixing bolt 2 continues to rotate, the first top plate 5 begins to exert pressure on the first spring 6, causing it to compress. The elastic force of the first spring 6 reacts to the connection between the fixing bolt 2 and the T-block 3, enhancing its stability. Next, the force of the second spring 10 is used to push the second top plate 9, thereby driving the slide bar 8 to move downward. This process continues until the support plate 11 is completely attached to the surface of the workbench, providing additional stability for the fixture. This not only ensures the stability of the device during processing, but also effectively extends the service life of the fixture by reducing damage that may be caused by vibration or misalignment.

[0024] Reference Figure 1 and Figure 3 The limiting assembly includes a screw 18, the outer wall of the screw 18 is slidably connected to the inside of the locking plate 12, and the outer wall of the screw 18 is threadedly connected to a nut 19; one end of the first spring 6 is fixedly connected to the inside of the sliding seat 4, the other end of the first spring 6 is fixedly connected to the outer wall of the first top plate 5, one end of the second spring 10 is fixedly connected to the inside of the fixing seat 7, and the other end of the second spring 10 is fixedly connected to the outer wall of the second top plate 9; the inner thread of the locking plate 12 is connected to the limiting bolt 13, and a limiting hole 14 is provided inside the fixed bottom plate 1, and the outer wall of the limiting bolt 13 is threadedly connected to the inside of the limiting hole 14; the outer wall of the locking plate 12 is fixedly connected to a slide plate 15, and the outer wall of the slide plate 15 is slidably connected to the inside of the fixed bottom plate 1; the inner thread of the slide plate 15 is connected to a movable bolt 16, and the outer wall of the movable bolt 16 is threadedly connected to the inside of the fixed bottom plate 1; a slide groove 17 is provided inside the fixed bottom plate 1, and the outer wall of the slide plate 15 is slidably connected to the inside of the slide groove 17;

[0025] Specifically, when the position of the locking plate 12 needs to be adjusted, it is only necessary to gently push the locking plate 12 to make it slide on the surface of the fixed base plate 1. When the locking plate 12 slides to a specific position, it can be fixed in the corresponding limiting hole 14 by rotating the limiting bolt 13. The locking plate 12 is fixed by tightening the limiting bolt 13. This is not only simple and practical, but also can ensure that the locking plate 12 remains stable during operation and will not move due to external forces. In addition, by rotating the movable bolt 16, the slide plate 15 is fixed inside the fixed base plate 1, thereby further fixing the position of the locking plate 12. This not only improves the stability of the locking plate 12, but also makes the entire fixer stronger and more reliable.

[0026] Working principle: when it is necessary to firmly fix the fixed base plate 1, the fixing bolt 2 is rotated toward the inside of the T-block 3, so that the fixed base plate 1 and the T-block 3 can clamp the workbench, and then the fixed base plate 1 is preliminarily fixed. At the same time, the fixing bolt 2 will push the first top plate 5 to compress the first spring 6 when rotating, so that the first spring 6 can use elastic force to strengthen the connection between the fixing bolt 2 and the T-block 3, and then the second top plate 9 is pushed by the second spring 10 to drive the slide bar 8 to move downward until the support plate 11 is completely close to the workbench, thereby achieving the effect of firmly fixing the fixture on the processing platform, improving the stability of the fixture and extending the service life of the fixture. When it is necessary to adjust the position of the locking plate 12, the locking plate 12 is pushed to slide on the surface of the fixed base plate 1. When it reaches a specific position, the limit bolt 13 is rotated into the corresponding limit hole 14, and the movable bolt 16 is rotated to fix the slide plate 15 inside the fixed base plate 1, thereby achieving the effect of adjusting the position of the locking plate 12, improving the practicality of the fixture and expanding the scope of application of the fixture.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
