Description

Technical Field

[0001] The utility model relates to the technical field of milling machine clamps, in particular to a milling machine clamp with an angle adjustment function. Background Art

[0002] The milling machine fixture is a device used to clamp the workpiece on the milling machine. Its main function is to position and clamp the workpiece on the milling machine table to ensure that the workpiece has the correct position relative to the tool and the milling machine during the processing, so as to obtain the required processing accuracy. The use of milling machine fixtures can greatly improve the processing efficiency and processing accuracy of the milling machine and reduce the labor intensity of the operator. It is an indispensable and important tool in modern mechanical processing.

[0003] In the milling machine fixture, three-jaw clamps are often used to fix bolts and nuts. During the clamping process, the three clamping heads on the upper end of the clamp are pushed inward at the same time to clamp workpieces such as bolts and nuts, which has a better positioning effect on bolts and nuts.

[0004] The three-jaw milling machine furniture is a cylindrical rotating shaft base, which can drive the bolts and nuts to rotate so as to cut and trim the outer side of the workpiece. However, since the cylindrical base is an integrated design, it is difficult to adjust the angle, which makes it difficult to process the inclined surface of the workpiece. Therefore, a milling machine fixture with an angle adjustment function is proposed. Utility Model Content

[0022] 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.

[0023] A milling machine fixture with an angle adjustment function comprises a fixture assembly 1. The fixture assembly 1 is an existing workpiece processing clamping device, which clamps and fixes workpieces such as bolts or nuts through three clamping heads at its upper end, so as to perform subsequent edge trimming and cutting operations on the workpiece.

[0024] In this example, see Figure 1 and Figure 2 A turntable 2 is installed on the lower side of the clamp assembly 1, and a support block 4 is installed on the outer side of the upper end of the turntable 2. The support block 4 is slidably connected to the inside of the turntable 2 through a driving block 41 fixed on the lower side thereof, and the outer ends of the support block 4 are rotatably connected to connecting frames 5 on both sides. In the process of driving the support block 4 to slide by the driving block 41, the connecting frame 5 is deflected, thereby causing the angle of the clamp assembly 1 to change with respect to the horizontal position.

[0025] Specifically, an adjusting rod 42 is rotatably connected inside the turntable 2, and the adjusting rod 42 is threadedly connected inside the supporting block 4, so that the adjusting rod 42 can rotate to drive the driving block 41 to slide, and then the driving block 41 drives the supporting block 4 to slide.

[0026] Furthermore, a support 21 is fixed to one side of the outer end of the turntable 2, and two connecting parts 11 are fixed to one side of the outer end of the clamp assembly 1, and the support 21 is rotatably connected between the two connecting parts 11, so that the clamp assembly 1 can rotate through the connection between the connecting part 11 and the support 21 as the axis.

[0027] Furthermore, there are two connecting frames 5, and a connecting block 12 is connected to the end of the connecting frame 5 away from the support block 4. The connecting block 12 is fixed at the bottom of the clamp assembly 1, and the connecting block 12 is rotatably connected between the two connecting frames 5. When the support block 4 drives the connecting frame 5 to deflect by sliding, the connecting block 12 can drive one side of the clamp assembly 1 to lift. Since the clamp assembly 1 is rotatably connected to the support 21 through the connecting piece 11, the clamp assembly 1 can rotate through the connection between the connecting piece 11 and the support 21 as the axis, and the angle of the clamp assembly 1 changes.

[0028] In further embodiments, see Figure 2 and Figure 3A base 3 is installed on the lower side of the turntable 2, and a plurality of bolts are installed on the outer end of the base 3 for installing the base 3. The turntable 2 is rotatably connected to the inside of the base 3 through a gear ring 6 fixed at the bottom thereof, so that the clamp assembly 1 can be rotatably adjusted on the base 3 through the turntable 2.

[0029] Furthermore, a driving gear 7 is installed on the bottom of the inner end of the base 3, and the driving gear 7 is rotatably connected to the base 3 through a driving rod 71 fixed at the bottom thereof, wherein the driving gear 7 can be connected to the driving assembly through the driving rod 71, and the driving rod 71 is driven by the driving assembly to rotate, thereby rotating the driving gear 7. The driving assembly can adopt the existing rotating driving equipment, so it is not elaborated here, and a plurality of tooth blocks are installed on the inner side of the bottom of the gear ring 6, and the gear ring 6 is meshed with the driving gear 7 through the tooth blocks, and can drive the gear ring 6 to rotate when the driving gear 7 rotates, thereby causing the turntable 2 to drive the clamp assembly 1 to rotate, so as to rotate the clamp assembly 1 after the angle adjustment to a suitable orientation to clamp the workpiece.

[0030] First, fix the base 3 on the processing track or workbench with bolts. When the workpiece needs to be cut or trimmed, the workpiece is clamped and positioned by the three clamping heads on the clamp assembly 1. When the workpiece bevel needs to be cut or trimmed, start the drive motor 43 to drive the adjusting rod 42 to rotate, and then the drive block 41 drives the support block 4 to slide, so that the connecting frame 5 is deflected and one side of the clamp assembly 1 is lifted through the connecting block 12. At this time, the clamp assembly 1 rotates through the connection between the connecting piece 11 and the connecting block 12 as the axis, so that the angle of the clamp assembly 1 changes. After the angle adjustment of the clamp assembly 1 is completed, the drive rod 71 is driven to rotate by the drive assembly, and then the drive gear 7 drives the gear ring 6 to rotate. At this time, the turntable 2 drives the clamp assembly 1 to rotate, and the position of the clamp assembly 1 after the angle adjustment is completed is adjusted to the required orientation. After the adjustment is completed, the workpiece can be cut or trimmed.
