Abstract
The invention relates to a bottom-top clamping tool set fixture for machining a sheet tension test sample. The fixture comprises an upper clamp plate, a lower clamp plate, side plates, a hydraulic ram, a base plate, sideface baffles and a powerful magnet; the upper clamp plate is arranged on the upper part of the fixture, the lower clamp plate is arranged below the upper clamp plate, a frame structure is formed by two side plates which are arranged between the upper clamp plate and the lower clamp plate, the sideface baffle is fixed on the side plates, the powerful magnet is arranged in the lower clamp plate, and the hydraulic ram is arranged on the base plate and connected with the lower clamp plate by a connecting bolt. The fixture has the advantages of high-precision machining of the tension test sample, convenient operation and low labor intensity, thus effectively reducing the labor intensity of operators.
Description
Technical field
The present invention relates to a kind of bottom-top clamping tool jig of machining sheet pulling force sample.
Background technology
The technological process ubiquity of each big steel enterprise processing pulling force sample processing process length at present, operator's labour intensity is big, machining precision is low, shortcomings such as efficient is low, the employing special purpose machine tool that has, also there is certain shortcoming: 1, can only process calibration apart from sample, can not satisfy the processing request of various gauge length samples.2, it is asymmetric to be prone to the sample shoulder, and the defective of poor surface smoothness influences accuracy of detection, can not satisfy the relevant criterion requirement fully.3, incompatibility all-the-way tracking extensometer is measured the requirement of elongation after fracture automatically.4, change the cutter inconvenience.
Summary of the invention
The objective of the invention is to have overcome deficiency of the prior art, a kind of simple to operate, bottom-top clamping tool jig that is used for machining sheet pulling force sample that machining precision is high is provided.
For achieving the above object, the present invention is achieved through the following technical solutions:
The bottom-top clamping tool jig that is used for machining sheet pulling force sample, it is characterized in that: comprise top board, lower platen, side plate, hydraulic jack, base plate, side board, top board is located at jig top, lower platen is located at the below of top board, and form framed structure by two blocks of side plates that are arranged between top board and the lower platen, side board is fixed on the side plate, and hydraulic jack is installed on the base plate, and is connected with lower platen by coupling bolt.Be provided with strong magnets in lower platen inside.
Compared with prior art, the invention has the beneficial effects as follows:
1, the machine-shaping that on a numerical control vertical machining centre, once is installed, the machining precision height, the automaticity height, the efficient height, easy to operate, labour intensity is low, and machining precision is not influenced by human factor.
2, satisfy of the requirement of various standards to the gauge length of pulling force sample parallel portion, precision, smooth finish, form tolerance.
3, this jig can also be processed the clod wash sample, the length scaling of impact specimen.
Can also be processed into sample parallel portion centre than little 0.02mm of normal parallel portion or 0.04mm when 4, processing the pulling force sample and improve the probability of sample, satisfy the requirement that the all-the-way tracking extensometer is measured elongation after fracture automatically in the centre fracture.

Among the figure: 1-top board 2-lower platen 3-hydraulic jack 4-side plate 5-side board 6-base plate 7-strong magnets
Embodiment
See Fig. 1, Fig. 2, Fig. 3, a kind of bottom-top clamping tool jig that is used for machining sheet pulling force sample comprises top board 1, lower platen 2, hydraulic jack 3, side plate 4, side board 5, base plate 6, strong magnets 7.Top board 1 is located at jig top, lower platen 2 is located at the below of top board, and connect to form framed structure by coupling bolt by the two blocks of side plates 4 that are arranged between top board 1 and the lower platen 2, side board 5 is fixed on the side plate 4, strong magnets 7 is arranged at lower platen 2 inside, hydraulic jack 3 is installed on the base plate 6, and is connected with lower platen 2 by coupling bolt.
As required one or more jigs can be installed on base plate 5, one or two oil cylinder can be selected in each jig unit.Base plate is fixed by bolts on the numerical control machining center equipment by fixed orifice.
Machining process is:
1, the blank sample is put between jig top board 1 and the lower platen 2, carried out centering with side board 5, strong magnets 7.
2, drive hydraulic jack 3 lower platen 2 is moved upward, sample is clamped between top board 1 and the lower platen 2.
3, adopt numerical control machining center processing, option program.
4, adopt the rough cut milling cutter, follow procedure carries out brute force cutting fast to bilateral, through several times sample being processed into the width that needs.
5, roughing milling cutter is return in tool changing, changes the finish-milling cutter into, and the sample parallel portion is carried out finish-milling.And the centre, the little 0.02mm of physical size or the 0.04mm that are processed into than parallel portion improve the probability of sample in the centre fracture, satisfy the requirement that the all-the-way tracking extensometer is measured elongation after fracture automatically.Processing clod wash, impact specimen are without this process.
Claims (2)
1, the bottom-top clamping tool jig that is used for machining sheet pulling force sample, it is characterized in that: comprise top board, lower platen, side plate, hydraulic jack, base plate, side board, top board is located at jig top, lower platen is located at the below of top board, and form framed structure by two blocks of side plates that are arranged between top board and the lower platen, side board is fixed on the side plate, and hydraulic jack is installed on the base plate, and is connected with lower platen by coupling bolt.
