Technical Field

The utility model relates to a measure inspection technical field, in particular to split type detection round pin.

Background

At present, metal processing products in the machining field are made smaller and smaller, the size requirement is higher and higher, and the size of a plurality of inner holes needs to be checked by using a measuring tool. The fastest way to check the size of the internal bore is to use a test pin inserted into the bore for the purpose of checking.

But traditional detection round pin formula as an organic whole appears wearing and tearing easily after repeated inspection many times, because the detection round pin after wearing and tearing influences the testing result, so can only change, and the integral type detects the whole change of round pin and has improved use cost greatly.

In order to solve the technical problem, the utility model provides a split type detection pin, which comprises a detection pin body, a taper sleeve guide post and a handle;

the detection pin body is in tight fit with one end of the taper sleeve guide post through a conical surface;

the handle is fixedly connected to the other end, far away from the detection pin body, of the taper sleeve guide column through threads;

the detection pin body consists of a conical head and a detection head, and the detection head is fixedly connected to the thick end of the conical head;

the conical head is gradually reduced in diameter from one end of the detection head, so that an external conical surface is formed.

Optionally, a fracture groove is formed at the contact position of the detection head and the conical head.

Optionally, two ends of the taper sleeve guide post are respectively provided with a taper sleeve and a threaded hole, and the threaded hole is communicated with one end of the taper sleeve.

Optionally, the taper sleeve is gradually reduced in diameter from one end of the taper sleeve guide column, so as to form an inner conical surface.

Optionally, the handle comprises handle and screw head, screw head fixed connection in the one end of handle.

Optionally, platforms are arranged on two sides of the handle, and gauge numbers are engraved on the platforms.

Optionally, the circumferential surface of the grip is engraved with a pattern.

The utility model provides a split type detection pin, which comprises a detection pin body, a taper sleeve guide post and a handle; the detection pin body is in tight fit with one end of the taper sleeve guide post through a conical surface; the handle is fixedly connected to the other end, far away from the detection pin body, of the taper sleeve guide column through threads; the detection pin body consists of a conical head and a detection head, and the detection head is fixedly connected to the thick end of the conical head; the conical head is gradually reduced in diameter from one end of the detection head, so that an external conical surface is formed. This split type detection round pin compares with traditional integral type detection round pin, when detecting the head and appearing wearing and tearing, only needs to be changed detect the round pin body, shorten maintenance duration, practice thrift the cost, and taper sleeve guide post with the handle can used repeatedly, greatly reduced use cost.

Detailed Description

The following describes a split-type detection pin according to the present invention in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

The utility model provides a split type detection pin, the structure of which is shown in figure 1 and figure 2, comprising a detection pin body 1, a taper sleeve guide post 2 and a handle 3; the detection pin body 1 is in tension fit with one end of the taper sleeve guide column 2 through a conical surface; the handle 3 is fixedly connected to the other end, far away from the detection pin body 1, of the taper sleeve guide column 2 through threads; the detection pin body 1 consists of a conical head 11 and a detection head 12, and the detection head 12 is fixedly connected to the thick end of the conical head 11; the conical head 11 is gradually reduced in diameter from one end of the detection head 12, so that an external conical surface 111 is formed; detect head 12 with conical head 11 contact position is opened there is rupture groove 13, works as it receives during too big pressure to detect head 12 in waiting to examine the hole, it can to detect head 12 rupture groove 13 position fracture to prevent that the operator from waiting to examine the hole too little will be forced detect head 12 inserts and wait to examine in the hole, thereby guarantee the qualification rate of inspection.

Specifically, as shown in fig. 3, two ends of the taper sleeve guide post 2 are respectively provided with a taper sleeve 21 and a threaded hole 22, the threaded hole 22 is communicated with one end of the taper sleeve 21, when the detection head 12 needs to be replaced, a push rod is directly inserted from the end of the threaded hole 22 to eject the detection head 12, and the split detection pin can be reused by replacing the detection pin body 1, so that the maintenance time is shortened, and the cost is saved; the taper sleeve 21 is gradually reduced in diameter from one end of the taper sleeve guide post 2, so as to form an inner tapered surface 211, and the inner tapered surface 21 is in interference fit with the outer tapered surface.

Specifically, as shown in fig. 4 and 5, the handle 3 is composed of a grip 31 and a screw head 32, the screw head 32 is fixedly connected to one end of the grip 31, and the handle 3 and the taper sleeve guide post can be fixedly connected by screwing the screw head 32 into the threaded hole; platforms 33 are arranged on two sides of the handle 31, and gauge numbers are engraved on the platforms 33; the circumferential surface of the grip 31 is carved with patterns, so that the friction force between the grip and the hand is increased, and the grip is convenient for an operator to use.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
