Embodiment 1

[0029] The present invention provides an NC machine tool machining a positioning jig, such as concrete Figure 1 to 4 Shown, comprises a base body 1 and the clamp, the clamp including a body clamp assembly and a lifting device; elevating means is provided on the base 1, the clamping assembly is provided on the lifting means and slidably connected to the lifting device;

[0030] A first clamp assembly comprising a first strut support plate 2, strut 3 and the second adjusting screw 4, a first support plate 3 are arcuate structure 2 and the second support plate and disposed opposite to the area of ​​the second support plate is greater than 3 2 of board area. The first purpose of support plate 2 and the second support plate 3 is placed constitutes a curved space, the area of ​​the second support plate 3 is larger than the area of ​​the first support plate 2 lies in the need to adjust the distance between the two supporting plates. 2 the lower end of the first supporting plate is provid...

Embodiment 2

[0037] In this embodiment, if Image 6As shown, the clamp body is at least two groups, and the two sets of clamp body spacers are disposed on the base 1.

[0038] Further, in the present embodiment, the slot 16 is opened on the base 1, and the electric roller 17 is provided at the bottom of each hydraulic cylinder 13, and the electric roller 17 is disposed within the chute 16. The two sets of clamp body can move along the slot 16 in the drive of the electric roller 17, and adjust the distance between the two sets of clamp body. When the clamp is longer, the clamping strength and stability of a set of clamp body do not meet the requirements, at which time it is necessary to use at least two sets of clamps, and the two ends of the clamping member are placed in a clamp body. In the placement space, the workpiece is clamped by adjusting each clamping screw.

[0039] The fixture provided by the embodiment is capped by clamping assemblies, facilitating the work of workers, and improving ...

Abstract

The invention provides a positioning fixture for machining of a numerically controlled machine tool, which belongs to the technical field of mechanical processing, comprising: a first horizontal extension plate is provided at the lower end of the first support plate of the clamping assembly, and a second horizontal extension plate is provided at the lower end of the second support plate. plate, the outer side of the second horizontal extension plate is provided with a strip-shaped groove for accommodating the first horizontal extension plate, the outer side of the first horizontal extension plate is stuck in the strip-shaped groove, and the two sides of the strip-shaped groove are provided with adjustment grooves, and the adjustment screw Through the adjustment groove and the first horizontal extension plate and screwed with the first horizontal extension plate; the side walls of the first support plate and the second support plate are provided with a first clamping screw near the upper end, and the end of the first clamping screw A first clamping plate is provided, a second clamping screw is provided near the lower end of the side walls of the first support plate and the second support plate, and a second clamping plate is provided at the end of the second clamping screw. The invention can clamp objects in multiple directions through the clamping components, which is convenient for coordinating workers' related work and improving work efficiency.

Description

Technical field [0001] The present invention belongs to the technical field of mechanical machining, in particular to a CNC machine for machining a positioning jig. Background technique [0002] Mechanical fixture manufacturing process for securing the object, so as to occupy the correct position to accept the construction or detection means, in order to ensure production quality, when machining the workpiece, the surface of the workpiece to achieve a predetermined drawing the size, geometry and the mutual position accuracy of the technical requirements of the other surface, the workpiece must be processed before the installed position, the clamping clipped, so as to produce qualified products. [0003] However, conventional machining jig is positioned relatively simple, can not meet the demand for multi-directional positioning, and are not universal. [0004] Accordingly, the present invention provides a CNC machine for machining a positioning jig. Inventive content [0005] To...
