Abstract

The utility model relates to a cylindrical edge finder, which comprises a cylinder and round magnets, wherein the edge finder is a three-quarter cylinder, so two planes in the radius direction are formed on the cylinder and are mutually vertical, two round holes are respectively formed on the two planes, the magnets are arranged in the holes, the surfaces of the magnets are lower than the planes, and the center of the edge finder is also provided with a cylindrical keep-space groove coaxial with the edge finder. When the cylindrical edge finder is used for finding a reference line, only the two planes with the magnets are needed to be adsorbed on workpiece surfaces, because the surfaces of the magnets are lower than the planes of the edge finder, and the keep-space groove is formed, the edge finder can be ensured to be tightly pasted on the workpiece surfaces, and the precision is ensured.

Description

A kind of cylindricality is sought the limit device

Technical field

The utility model relates to field of machining, and especially a kind of cylindricality is sought the limit device.

Background technology

Usually on the workpiece some requisite angularity holes are arranged, the inclined hole that has be folk prescription to gradient, have plenty of both direction gradient (being compound gradient), as the oblique top via hole that often has on the mould, tiltedly transport the water hole, tiltedly core-drawing hole etc.In the process of these inclined holes of processing, at first we must be as the criterion with the actual grade of inclined hole, workpiece are put the position of suitable processing inclined hole.Because tiltedly original reference side plane is with respect to bumping for the counting apparatus that oneself is in N gradient state on the lathe on the workpiece of back for pendulum, can't get base value from the side of workpiece with normal method this moment at all.Be to solve the peek problem, the common practice is, processes a standard station with respect to inclined hole in advance on workpiece, in order to peek, or makes the technology tool and makes a standard station on tool, in order to peeking.More than two kinds to make the method for standard station in advance, the accumulated error that machining accuracy must be arranged, reduced precision, particularly large-scale workpiece largely depends on the tool peek, and tool is only useful at a certain gradient, has only the hole of identical gradient just can apply mechanically this tool again, that is to say that the technology tool all is disposable use basically, no mutual circulation usability has increased process time and cost.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of cylindricality and seeks the limit device, can conveniently find the benchmark crest line of wanting.

For addressing the above problem, cylindricality of the present utility model is sought the limit device and is comprised cylinder and circle magnet, cylinder is 3/4 cylinder, two planes along radial direction are arranged on the cylinder, these two planes are vertical mutually, be adsorbed on the workpiece in order to make cylindricality seek the limit device, seek in cylindricality on two planes of limit device and respectively open two circular holes, and in circular hole, be placed with magnet, magnet surface is not higher than the plane at its place, can guarantee that like this cylindricality seeks two planes of limit device and can tightly be attached on the surface of workpiece, cylindrical center have one with the cylinder cylindrical groove of totally one axis, when the edge of workpiece chamfering is arranged like this, perhaps during edge of work out-of-flatness, can guarantee that still cylindricality seeks surperficial gapless being close together of two faces and the workpiece of limit device.

Beneficial effect

The utility model is simple in structure, operate simple and easy, the precision height, not fragile, and cost of manufacture is cheap.Workpiece after putting for the monocline degree is sought the limit and is had that operation is simple and easy seeks advantages such as the limit is quick, and tool versatility (being not limited to a certain workpiece), can work as conventional tool to make, and produces sale in batches.

Description of drawings

Fig. 1 seeks limit device structure chart for cylindricality.

Fig. 2 has the schematic diagram of putting that the inclined hole workpiece adds man-hour.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

As shown in Figure 2, workpiece 6 is put to the required gradient of processing, firm is fixed on the workbench, begin to seek the limit action this moment: the first step, cylindricality is sought the intersection, two sides that limit device 8 is placed to workpiece, shown in figure four, by the attraction function power of seeking four magnet 2 on the device of limit, the two sides of seeking in the device of limit is pasted tightly mutually with the two sides of workpiece, face pastes mutually and can not gappedly (can influence precision with face, must clear up in advance surface of the work and seek device surface, limit, as flash removed etc., the circular avoiding hollow groove of seeking on the device of limit has just been brought into play its effect at this moment); Second step, with square bump plane, several instruments 7 left side toward directions X with seek the limit device and crash gently, find square body side plane and the directions X of seeking limit device periphery tangent line (point) P mutually, since on the periphery on the tangent line each any point all equate (being the cylinder radius) to the distance of cylinder axis, the distance that therefore can get P and cylinder axis equals to seek the radius value of limit device, seek the method on limit by seeking the limit device, even if seamed edge has chamfering on the workpiece, also can find the peek sideline on the workpiece easily, find-the peek benchmark sideline of Z direction with same operating principle again.The 3rd step, after the peek datum line finds, zero clearing on the electronic ruler of lathe (as reference coordinate), but carry out required processing with regard to the basis of reference coordinate then.
