[0045] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0046] Figure 1 FIG. 1 is a schematic diagram showing a manual chamfering fixture structure of an embodiment of the present invention, please refer to FIG. Figure 1 The present embodiment discloses a manual grinding and chamfering jig, comprising a tooling plate 1, a rotating rod 2, a placement mechanism 3, a positioning mechanism 4 and a pressing mechanism 7, wherein the rotating rod 2 is used to drive the placement mechanism 3 to rotate, the positioning mechanism 4 is slidably connected to one end of the rotating rod 2, and is used to position the rotating rod 2, and the pressing mechanism 7 is used to press the processed parts in the placement mechanism 3 to prevent the parts from loosening during grinding.

[0047] Among them, the tooling plate 1 includes a horizontal plate 11 and a vertical plate 12, which are cross-shaped and integrally formed. The length of the horizontal plate 11 is greater than the length of the vertical plate 12, and the width of the horizontal plate 11 is less than the width of the vertical plate 12. A through groove 13 is set in the middle of the vertical plate 12.

[0048] Both ends of the rotating rod 2 pass through the vertical plate 12 and are equipped with ball bearings at the connection. The ball bearings can limit the rotating rod 2 to only rotate but not move axially, so that the entire fixture can operate better. The part of the rotating rod 2 located inside the through groove 13 is evenly distributed with multiple placement mechanisms 3 for placing processed parts, and the processed parts can extend out of the bottom of the vertical plate 12, that is, during grinding, the processed parts can contact the sandpaper. The height of the placement mechanism 3 is less than the height of the vertical plate 12 to prevent a corner of the placement mechanism 3 from conflicting with the sandpaper during rotation, thereby preventing the rotating rod 2 from rotating. In order to better avoid this situation, the bottom surface of the placement mechanism 3 is set to an inverted trapezoidal structure, so that there is a certain angle between its bottom surface and the sandpaper in the initial state. During rotation, due to the existence of the angle, it can further avoid a corner of the placement mechanism 3 from conflicting with the sandpaper, thereby improving the smoothness of the operation of the fixture.

[0049] When the manual grinding and chamfering jig disclosed in the present embodiment is working, first the entire jig is placed on the surface of the sandpaper, then the processed part is placed in the placement mechanism 3, and the rotating rod 2 is rotated so that the angle between the processed part and the sandpaper is consistent with the angle to be chamfered, and then the rotating rod 2 is positioned by the positioning mechanism 4, and the processed part is pressed by the pressing mechanism 7, and the tooling plate 1 is pushed back and forth for grinding. The whole process is simple to operate, and there will be no angle deviation during the processing process, which improves the yield rate of the produced products, reduces unnecessary losses caused by too high a defective rate, and further improves production efficiency.

[0050] Please refer to Figure 5The placement mechanism 3 includes a placement plate 31 arranged on the rotating rod 2. The placement plate 31 is arranged to have an inverted trapezoidal structure at the bottom. A groove 32 for placing the processed parts and vertically passing through the placement plate 31 is provided on the placement plate 31. When working, the processed parts can be placed in the groove 32.

[0051] Please refer to Figure 2-6 The positioning mechanism 4 includes a sliding rod 41, a plug rod 42, a reset spring 43 and a guide block 44. The sliding rod 41 is slidably connected to one end of the rotating rod 2, and the rotating rod 2 is provided with a slide groove 21 for the sliding rod 41 to slide; there are two plug rods 42, and the two plug rods 42 are respectively provided at both ends of the sliding rod 41, and when positioning, the end of the plug rod 42 away from the sliding rod 41 is inserted into the vertical plate 12. Specifically, when rotation is required, first pull the sliding rod 41 outward to pull the plug rod 42 out of the vertical plate 12, and then rotate the rotating rod 2. When it is rotated to a specified angle, push the sliding rod 4 inward to insert the plug rod 42 into the vertical plate 12 to complete the positioning, and the operation is simple and convenient.

[0052] Please refer to Figure 3 and Figure 6 The positioning mechanism 4 also includes a return spring 43 disposed inside the slide groove 21 for pushing the plug rod 42 into the vertical plate 12. One end of the return spring 43 is fixedly connected to the side of the sliding rod 41, and the other end is fixedly connected to the inner wall of the slide groove 21. In specific operation, in the initial state, the plug rod 42 is plugged into the vertical rod 12. When the angle needs to be changed, the sliding rod 41 is pushed outward, and the sliding rod 41 compresses the return spring 43. The return spring 43 accumulates rebound force. When the angle of the part is adjusted, due to the rebound force, the return spring 43 automatically bounces the plug rod 42 into the vertical rod 12. There is no need to manually insert the plug rod 42 into the vertical rod 12, and the operation is simpler and faster. In addition, the return spring 43 is preferably a compression spring. Compared with ordinary springs, the compression spring can better play the role of its rebound force, making reset more convenient.

[0053] Please refer to Figure 6 Two guide grooves 22 are symmetrically arranged inside the slide groove 21, and a guide block 44 matching the two guide grooves 22 is arranged on the side of the sliding rod 41. In this way, when the sliding rod 41 slides, it will always move around the guide groove 22, and no axial deflection will occur during the movement, thereby improving the smoothness of operation and work efficiency.

[0054] Preferably, an annular groove 14 is provided on the side of the vertical plate 12 for the plug-in rod 42 to rotate, and a plurality of slots 15 matching the plug-in rod 42 are provided inside the annular groove 134, and each slot 15 corresponds to a different angle, so that the plug-in rod 42 can always rotate inside the annular groove 14, further ensuring that no deflection occurs during the rotation process. By inserting the plug-in rod 42 into the slot 15, the structure is simple and easy to operate.

[0055] Please refer to Figure 1-6 The manual grinding chamfering jig also includes a pressing mechanism 7 for positioning the processed parts. The pressing mechanism 7 includes a mounting frame 71, a cylinder 72, a pressing plate 73 and a pressing column 74. The mounting frame 71 is arranged at the top of the vertical plate 12, the cylinder 72 is arranged at the top of the mounting frame 71, the pressing plate 73 is arranged below the mounting frame 71, and is connected to the cylinder 72 by transmission. There are multiple pressing columns 74, and the multiple pressing columns 74 are evenly distributed at the bottom of the pressing plate 73, and the pressing columns 74 match the width of the groove 32. Specifically, during operation, when the processed parts are placed, the cylinder 72 is started, thereby driving the pressing plate 73 to move downward, so that the pressing column 74 presses the parts, and starts to grind the parts to ensure that the parts will not be offset. Preferably, a soft rubber column is arranged at one end of the pressing column 74 that contacts the parts. When pressing, the soft rubber column will deform to adapt to the top surface of the parts, so as to better press the parts.

[0056] An angle gauge 6 is provided at the other end of the rotating rod 2. When the rotating rod 2 rotates, the angle gauge 6 displays the rotation angle. The angle rotated by the rotating rod 2 can be more intuitively displayed on the angle gauge 6, thereby better ensuring the efficiency of angle adjustment.

[0057] Rollers 5 are provided on both sides of both ends of the transverse plate 11. The rollers 5 are used to push the jig to move and convert the sliding friction into rolling friction, making the grinding process more convenient and improving production efficiency.

[0058] Through the above technical scheme, the present invention discloses a manual grinding chamfering jig, by setting a plurality of placement mechanisms 3 for placing processed parts in the middle of the vertical plate 12, driving the placement mechanisms 3 to rotate different angles by rotating the rotating rod 2 to adapt to different angles of the parts, and then positioning the rotating rod 2 by the positioning mechanism 4, so that no angle deflection will occur during the grinding process on the sandpaper, reducing the output rate of defective products, improving production efficiency, and reducing production losses. In addition, the present invention is simple to operate, easy to use, and low in cost.

[0059] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
