Description

Quick positioner of lathe processing pole

Technical Field

The utility model relates to the field of machinary, a lathe processing pole quick positioner specifically says so.

Background

Currently in the processing of tensile specimens, for hot working and heat treating seamless tubes, the transverse specimens should be round bar specimens and taken from non-flattened test blocks. For other steel tubes, the transverse specimen may be either a plate specimen or a round bar specimen, the plate specimen being taken from the flattened block and the round bar specimen being taken from the unplated block. Because the tensile test samples are all transversely cut along the steel pipe, and the strip-shaped test sample block is not allowed to be flattened before the round bar test sample is processed, the tensile test sample round bar is processed by using a common lathe fixture under the condition that the test sample block has radian, the center position is difficult to determine, the processing efficiency is low, and the coaxiality of the processed round bar test sample is poor.

Disclosure of Invention

In order to overcome the not enough of difficult definite central point position, machining efficiency low, sample axiality difference when current processing pole sample, the utility model provides a lathe processing pole quick positioner, this lathe processing pole quick positioner can fix a position sample central point fast and put, improve machining efficiency and sample axiality.

The technical scheme of the utility model is that: the utility model provides a lathe processing pole quick positioner, includes the body, it has square anchor clamps mouth to open on the body, and it has first bolt hole and the second bolt hole that communicates with each other with the anchor clamps mouth to open on the body, and first bolt hole and second bolt hole perpendicular to anchor clamps mouth two adjacent sides respectively.

The clamp opening is square, and the four planes of the clamp opening are A, B, C, D in sequence, wherein a first bolt hole is communicated with the surface C, and a second bolt hole is communicated with the surface D; the distance between the surface A and the center O of the clamp opening is h1, the distance between the surface B and the center O of the clamp opening is h2, and h1 is h 2.

The side length of the clamp opening is H, and H >2H 1.

The utility model discloses following beneficial effect has: by adopting the scheme, the device can ensure the coaxiality of the processed cambered surface strip-shaped sample, improve the accuracy of the sample result and avoid the deviation of the test result caused by processing errors; the size of a strip-shaped sample does not need to be measured, the sample is directly placed into the position of a fixed clamping opening of the device, and the central position of the sample can be automatically determined; put into the centre gripping with rectangular shape arc sample in, need not the adjustment, can ensure the sample levelness, for lathe machining precision provides the assurance, improve work efficiency.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in figures 1 to 3, the quick positioning device for the round rod machined by the lathe comprises a body 1, wherein the body 1 is a cylinder, a square clamp port 2 is formed in the body 1, the axial direction of the clamp port 2 is consistent with that of the body 1, and one end of the clamp port 2 is closed. The side wall of the body 1 is provided with a first bolt hole 3 and a second bolt hole 4 which are communicated with the clamp opening 2, the first bolt hole 3 and the second bolt hole 4 are respectively vertical to two adjacent side surfaces of the clamp opening 2, and the two bolt holes are corresponding to each other along the axial position of the body 1.

The clamp opening 2 is preferably square, for convenience of description, four sides of the square are named as four planes respectively, the four planes are A, B, C, D in sequence, wherein the first bolt hole 3 is communicated with the surface C, and the second bolt hole 4 is communicated with the surface D; the distance between the surface A and the center O of the clamp opening is H1, the distance between the surface B and the center O of the clamp opening is H2, and the side length of the clamp opening 2 is H, wherein H1 is H2, and H is more than 2H 1.

The first embodiment is as follows: the diameter of the body 1 is 80mm, the length of the body is 150mm, the depth of the clamp opening 2 is 70mm, and the distance from the first bolt hole 3 and the second bolt hole 4 to the end part of the body 1 is 20 mm; the side length of the clamp opening 2 is H =24mm, and H1 is H2 is 10 mm.

When a sample is clamped, the sample is placed in the clamp opening 2, the sample is tightly attached to the surface A and the surface B, the surface A and the surface B are used for positioning the sample, then the two bolts are screwed on the first bolt hole 3 and the second bolt hole 4 respectively, the sample is tightly jacked, and the other two surfaces of the sample are positioned. Like this, when the tensile sample of lathe processing pole, both guaranteed the axiality of processing pole tensile sample, can effectively reduce simultaneously and measure the sample frequency, and need not to adjust repeatedly and confirm sample central point in the sample anchor clamps mouth of packing into, shorten the sample and pack into anchor clamps intraoral time greatly, the machining precision is high, improves work efficiency in the tensile sample processing of pole simultaneously.
