In addition to enlarging the cast or processed holes on the workpiece, the horizontal boring machine can also mill planes, drill, process the outer circle of end faces and flanges, and cut threads, etc. It is mainly used in single-piece small-batch production and repair workshops. The roundness error of the processed holes does not exceed 5 microns, and the surface roughness is Ra0.63~1.25 microns. The rotary fixture is mainly used to clamp and limit the workpiece, and then facilitate the subsequent processing of the horizontal boring machine.

[0003] The horizontal boring machine can mainly drill holes in the workpiece, and the purpose of the fixture is to keep the workpiece stable. However, traditional fixtures usually use two motors to drive and connect to clamp the two sides of the workpiece respectively, which not only increases the cost and consumes power, but also the transmission of the two motors takes a certain amount of time, which is not convenient enough. For this reason, a rotary fixture for a horizontal boring machine is designed, which can quickly clamp and separate the workpiece by rotation. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution of a rotary fixture for a horizontal boring machine:

[0022] Embodiment 1:

[0023] like Figure 1-3 As shown, a rotary clamp for a horizontal boring machine comprises a clamp seat 1, a threaded rod 2 is arranged inside the clamp seat 1, a fixed column 3 is arranged inside the clamp seat 1, a push block 4 is sleeved on one end of the threaded rod 2 and the fixed column 3, a bottom plate 6 is arranged on the top of the two push blocks 4, a processing panel 8 is arranged on the top of the bottom plate 6, a moving rod 7 is movably installed on one side of the top of the processing panel 8, one end of the moving rod 7 is slidably connected to the top of the bottom plate 6, a fixed rod 10 is fixedly installed on the top of the processing panel 8, the moving rod 7 is elastically connected to the outside of the fixed rod 10 by a reset spring 11, and a clamp is arranged on one end of the moving rod 7. The holding block 9 is provided with a rotating rod 12 inside, and a rotating rod 14 is provided at one end of the rotating rod 12. One end of the rotating rod 14 is rotatably connected to one end of the processing panel 8. The clamping block 9 moves at one end of the rotating rod 12, and the abutment block 13 does not contact with the raised part of the clamping block 9. When the reset spring 11 is in a tightened state, the bottom of the clamping block 9 abuts against one side of the workpiece surface, and the workpiece can be limited to the top of the processing panel 8. After continuing to rotate the rotating rod 12, the abutment block 13 gradually squeezes the raised part of the clamping block 9, applies pressure to the clamping block 9, and the reset spring 11 gradually extends and stretches.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, a clamping plate 15 is arranged on the top of the processing panel 8, and limiting blocks 16 are fixedly installed on both sides of the clamping plate 15, and limiting columns 17 are rotatably installed on one side of the two limiting blocks 16, and multiple limiting holes 18 are opened on both sides of the processing panel 8. The utility model is a rotary clamp for a horizontal boring machine. By setting the clamping plate 15, the limiting block 16, the limiting column 17 and the limiting hole 18, the clamping plate 15 can move back and forth on the top of the processing panel 8, so that the position of the clamping plate 15 clamping the workpiece can be adjusted according to the width of the workpiece, and one end of the two limiting columns 17 is sequentially embedded into the corresponding limiting holes 18.

[0026] Working principle: The horizontal boring machine can mainly drill holes in the workpiece. The purpose of the clamp is to keep the workpiece stable. At this time, the surface of the workpiece is located at the bottom of the clamping block 9, and the workpiece can be kept stable by the clamping block 9. The staff can place the workpiece on the surface of the processing panel 8, and then continue to rotate the rotating rod 12 to drive the rotating rod 14 to rotate on the top of the processing panel 8. At this time, the abutment block 13 is not in contact with the raised part of the clamping block 9, and the return spring 11 is in the tightened state. The bottom of the clamping block 9 and one side of the workpiece surface abut against each other, which can limit the workpiece to the top of the processing panel 8. The friction between the rotating rod 14 and the inside of the processing panel 8 is relatively large. When no pressure is applied to the rotating rod 12, the rotating rod 14 will remain stable inside the processing panel 8. That is, after rotating the rotating rod 12, the rotating rod 12 will always remain in a specific position and will not rotate. After continuing to rotate the rotating rod 12, the abutment block 13 gradually engages with the raised part of the clamping block 9. The workpiece is squeezed and pressure is applied to the clamping block 9. The return spring 11 gradually extends and stretches, driving the moving rod 7 and the clamping block 9 to move to one side, so that the clamping block 9 is gradually separated from the workpiece surface, and then the staff can pull the workpiece out from the processing position of the horizontal boring machine. The speed of workpiece limiting can be accelerated by rotation. The clamping plate 15 can move back and forth on the top of the processing panel 8, so that the position of the clamping plate 15 clamping the workpiece can be adjusted according to the width of the workpiece. One end of the two limiting columns 17 is successively embedded in the corresponding limiting holes 18, and the two are connected by threaded rotation, so that the processing panel 8 and the clamping plate 15 can be limited and fixed. At this time, the surface of the processed workpiece just fits the bottom surface of the clamping block 9. After starting the stepper motor 5, it will drive the threaded rod 2 to rotate, and then, under the action of the two pushing blocks 4, the position of the bottom plate 6 and the processing panel 8 on the top of the clamping seat 1 can be adjusted, thereby increasing the scope of use of the rotary clamp.
