Technical Field
The invention belongs to the technical field of galvanized sheet sample clamps, and particularly relates to a clamp for milling a galvanized sheet special-shaped sample.
Background
Currently, galvanized sheets are widely used in the automotive industry. In order to detect whether the mechanical properties of the galvanized sheet are qualified, a CNC machine tool is used for milling out a special-shaped sample with higher precision, as shown in FIG. 5, and the special-shaped sample is used for a tensile test.
Because the thickness of the galvanized sheet is 0.5-3.0mm, 10 pieces of coarse samples are required to be overlapped for improving the processing efficiency, and then milling processing is carried out. The stability of the overlapped samples is poor, and when the side surfaces are milled, the cutter and the compacting system vibrate greatly and are easy to move. The dimensional accuracy of the sample is out of tolerance, waste products appear, and the process is labor-consuming and time-consuming.
How to design a proper fixture, which can not only prevent the overlapping samples from moving without influencing the feeding path of the milling cutter in the processing process, but also meet the requirements of economy and economy, is a problem to be solved urgently.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide the fixture for milling the galvanized sheet special-shaped sample, which economically and economically solves the problem that the overlapped samples are shifted in the milling process, thereby meeting the precision requirement of a tensile test.
The invention aims at realizing the following steps: a fixture for milling galvanized sheet dysmorphism sample, its key lies in: the combined clamping piece comprises a limiting clamping piece and at least one pair of symmetrically arranged combined clamping pieces, wherein the limiting clamping piece comprises a limiting bottom plate and limiting ends arranged at two ends of the limiting bottom plate, limiting clamping grooves are formed in the inner sides of the limiting ends and the combined clamping piece, limiting protruding blocks are arranged on the outer sides of the combined clamping pieces, and the limiting protruding blocks are assembled in the corresponding limiting clamping grooves of the limiting ends or the other pair of combined clamping pieces. By adopting the structure, the two ends of the longer special-shaped sample can be directly placed in the limiting clamping groove of the limiting end head, the two side surfaces and the end surface of the special-shaped sample are positioned, the area required to be processed of the special-shaped sample is ensured not to be shielded, the shorter special-shaped sample can be provided with the combined clamping piece on the basis of the limiting clamping piece, or a pair of combined clamping pieces is continuously provided on the basis of the combined clamping piece, the special-shaped sample can be directly assembled between the pair of combined clamping pieces at the innermost side, further, the special-shaped samples with different types are ensured to be positioned, then the overlapped special-shaped samples are pressed by the hydraulic mechanism of the CNC machine tool, the special-shaped sample can be milled, the clamp can limit the transverse direction and the longitudinal direction of the special-shaped sample without generating movement, and the processing precision is ensured.
Further, slot holes for enlarging the space of the inner angle are arranged at the inner angles of the limiting clamping grooves, and the slot holes are communicated with the limiting clamping grooves. The internal angle of the original limiting clamping groove is used for interfering the overlapped placement of the special-shaped sample, the placement is not smooth, by adopting the structure, the space of the slotted hole is enlarged, interference is prevented, and meanwhile, the slotted hole can be used as a processing technology hole for processing the right angle of the special-shaped sample.
Further, the bottom surface of the limit clamping groove of the limit end is closed and is arranged coplanar with the upper surface of the limit bottom plate; the limiting clamping groove bottom opening of the combined clamping piece is arranged. By adopting the structure, the flatness of the bottom surface of the special-shaped sample is ensured.
Further, the width of the limiting clamping groove is suitable for the width design of the special-shaped sample. By adopting the structure, the special-shaped sample is further ensured to be limited by the limiting clamping groove, and the movement is prevented.
Furthermore, the depth design of the limiting clamping groove is higher than the overlapping height of the special-shaped samples. By adopting the structure, the limit clamping groove is ensured to be capable of processing a plurality of overlapped special-shaped samples.
Further, the limiting bottom plate and the limiting end are integrally formed. By adopting the structure, the strength of the limiting clamping piece is enhanced.
The beneficial effects are that:
the fixture for milling the galvanized sheet special-shaped sample, disclosed by the invention, is economical and economical, solves the problem that the overlapped samples are shifted in the milling process, further meets the precision requirement of a tensile test, is simple and convenient to use and operate, has an obvious effect, is verified by an operator, can be implemented, and is put into practical use.
