Description

TECHNICAL FIELD

[0001] The utility model relates to CNC (numerical control machine tool) four -axis processing fixture installation technical field, especially point to a kind of CNC (numerical control machine tool) when four -axis processing, workpiece or fixture is locked with draw-in nail on base plate, then the fast -mounting base plate of CNC four -axis processing with draw-in nail seat of four -axis processing is carried out. BACKGROUND

[0002] The conventional production mode of CNC (numerical control machine tool) four -axis processing is to make a bridge plate as base plate 2, and workpiece or fixture 3 is locked on base plate 2 by screw through screw hole 31 (as shown in the attached Figure 1 When transmission mechanism 4 is driven by driving motor 41, movement is generated by being driven by transmission mechanism 5, and then base plate 2 on machine table 1 carries out CNC four -axis processing on workpiece;This processing has the following shortcomings:

[0003] 1. Clamping mode is slow, and screwing is tedious;

[0004] 2. Poor accuracy, traditional clamping needs manual adjustment of clamping accuracy on machine table 1, and accuracy is directly related to the proficiency of staff;

[0005] 3. Due to the existence of workpiece or fixture 3, it is basically impossible to clamp on two surfaces of base plate 2, and the current market is all single-sided clamping cases, and the reason is that the speed of clamping affects the efficiency of two-sided clamping and is not considered feasible. SUMMARY

[0006] The utility model aims at overcoming the defects of prior art, and provides a fast -mounting base plate of CNC four -axis processing with draw-in nail seat, which can be quickly installed and does not change the original structure.

[0007] The utility model is realized by the following technical schemes:

[0008] The fast -mounting base plate of CNC four -axis processing with draw-in nail seat comprises machine table, transmission mechanism, driven mechanism and fast -mounting base plate, the transmission mechanism and the driven mechanism are oppositely arranged on the machine table, and the fast -mounting base plate is fixed on the connecting block of the transmission mechanism and the connecting block of the driven mechanism;The top surface of the fast -mounting base plate is provided with draw-in nail holes around the four corners of the work position of the workpiece to be processed, and the side surface of the fast -mounting base plate is provided with control knobs capable of locking the draw-in nails entering the draw-in nail holes;

[0009] The top surface and the bottom surface of the fast -mounting base plate are provided with draw-in nail holes around the four corners of the work position of the workpiece to be processed;

[0010] Two side surfaces are provided with control knobs capable of locking the draw-in nails entering the draw-in nail holes;

[0011] Each control knob can lock the rivets at the workstation of an adjacent workpiece.

[0012] This invention, by employing a rivet structure and a rivet locking device, changes the clamping method, eliminating the need for locking screws. The clamp kit is simply inserted into the corresponding rivet hole, and then locked by the tightening mechanism. This device directly solves the shortcomings of slow clamping and poor accuracy.

[0013] By placing the bridge plate at the center of the four axes and machining both sides into a usable centering base, this design allows for the simultaneous clamping of eight workpieces in a position that can only hold four workpieces, significantly improving processing efficiency.

[0014] When changing clamps, use external clamping to improve the clamping speed. Prepare an extra zero-point fixture. During CNC machining, change the workpiece on the worktable. After CNC machining is completed, replace the fixture in the machine tool with the changed workpiece and fixture. After clamping, enter the second round of CNC machining. During the machining time, the worker changes clamps externally and prepares for the third round of machining. This forms a machining cycle.

[0015] External clamping can also effectively avoid mechanical safety hazards caused by internal clamping. Attached Figure Description
