Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the present test stick removing apparatus includes:

the tool comprises a tool handle 100, wherein one end of the tool handle 100 is connected with a machine tool fixing rivet;

the tool 300 comprises a clamping part 310 and a working part 320 which are respectively arranged at two ends of the tool 300, the clamping part 310 is inserted into one end of the tool shank 100 far away from the machine tool fixing pull ring 200, and the working part 320 is positioned outside the tool shank 100.

The utility model provides a test rod remove device is applied to sampling equipment technical field.

In the metallographic sampling of the casting, the casting is pretreated as shown in fig. 3, a cylindrical test bar is drilled, and a positioning hole 400 is preformed on the cross section of the test bar by a center drill, wherein the positioning hole 400 is conical, but is not limited to conical. This test rod remove device passes through the fixed blind rivet of lathe and installs on the lathe main shaft, and according to numerical control program location alignment locating hole 400 on the test rod to notice the suitable interval between control locating hole 400 and the cutter 300 working part 320, use numerical control program control cutter 300's working part 320 to walk the circle in locating hole 400, drive the test rod and do circular motion around the centre of a circle, make the test rod fracture, take out.

Preferably, the working portion 320 is conical, the working portion 320 is matched with the positioning hole 400 in the pretreatment of the large casting, the conical positioning hole 400 is easy to prepare, therefore, the working portion 320 of the cutter 300 is preferably conical, and the conical vertex angle of the working portion 320 is preferably 95 degrees.

Further, both ends of the tool shank 100 are provided with cavities, the machine tool fixing rivet part extends into the cavity at one end, the clamping part 310 of the tool 300 extends into the cavity at the other end, and the tool shank 100 and the machine tool fixing pull ring 200 and the tool shank 100 and the tool 300 are in concave-convex fit, so that the tool shank is firmer.

Further, threaded connection is adopted between the tool holder 100 and the machine tool fixing rivet, the tool holder 100 and the machine tool spindle are connected through the machine tool fixing rivet, and the threaded connection is adopted to enable the connection to be firmer.

Further, the clamping portion 310 of the tool shank 100 and the tool 300 are in an interference fit, so that the two are connected more firmly.

Preferably, the tool holder 100 is a BT50 tool holder 100, and has the advantages of large clamping force, good rigidity and simple and flexible operation.

Preferably, the working portion 320 of the cutter 300 has a hardness of HRC58, and can be well matched with a test stick to perform circular motion, so that damage to the cutter 300 or the test stick is reduced.

The utility model has simple structure, easy installation and maintenance and reduced equipment cost; the whole working process is controlled by a numerical control program, so that human errors are reduced, potential safety hazards are reduced, and labor cost is reduced; the sampling time of the test rod is greatly shortened; protecting the casting and reducing unnecessary damage.
