Abstract
An adjustable reamer is characterized in that the adjustable reamer is provided with a tapered screw, a tapered hole is arranged in the reamer along the axis, and threads are arranged on the tapered hole; threads which are matched with the tapered hole are arranged on the tapered screw, so the tapered screw is enabled to be screwed in the tapered hole; one or more cutting lines which are evenly distributed are arranged between two cutting edges of the reamer, and the cutting lines are parallel to the axis of the reamer. According to the adjustable reamer, the tapered screw is arranged, so after the reamer is abraded, the reamer can move in the tapered hole by rotating the tapered screw, and then the reamer is forced to expand and is adjusted to needed size accuracy. The problems that a normal reamer has to be changed frequently, sizes are frequently adjusted and the like are solved, and the defects that an installation tool apron is prone to breakdown caused by frequent change of reamers and the like are overcome.
Description
Technical field
The utility model relates generally to the metal material field of machining, relates in particular to a kind of adjustable reamer.
Background technology
In the processing process of the machineries such as butterfly valve, axis hole belongs to the Precision Machining position, need to process with reamer, and common reamer will serious wear after with a period of time, the hole that processes will not reach desired precision, just must change reamer this time, this just needs to be equipped with multiple different reamer, when changing, need to unload reamer from lathe, change a new reamer and continue processing, the frequent reamer makes the installation tool rest break down easily, and impact is produced, and after newly reamer installs, just must proofread and correct again size, waste time and energy and can raise the cost; Same reamer in use can be subject to wearing and tearing in various degree in addition, and corresponding size also can change accordingly, and the user is as paying no heed to, and production and processing goes out undesirable product.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of frequent reamer that need not, and need not frequently to proofread and correct the adjustable reamer that the reamer size just can be processed the different size engineering goods.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of adjustable reamer, it is provided with a tapering screw; Described reamer offers a taper hole along axis, and described taper hole is provided with screw thread; Described tapering screw is provided with the screw thread that is complementary with taper hole, so that the tapering screw can screw in the taper hole; One or above equally distributed line of cut are set between described reamer two blades, and described line of cut is parallel to the reamer axis.
Be provided with scale on the described tapering screw.
The usefulness of technique scheme is:
1, the utility model can realize that by the tapering screw is set reamer is after wearing and tearing, can make it mobile in taper hole by rotation tapering screw, thereby force the reamer expansion and be adjusted to required dimensional accuracy, overcome common reamer frequent, frequently regulated the problem such as size, overcome simultaneously the frequent reamer and made easily the defectives such as tool rest breaks down are installed.
2, the utility model reamer is provided with scale at the tapering screw, so that the reamer diameter after the wearing and tearing can reach required size by adjusting, greatly prolonged service life, and reamer does not need dismounting, the reamer size is not just needed again to proofread and correct, not only the product of processing meets the requirements, and greatly saves time, and improves working (machining) efficiency.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the utility model reamer body structural representation;
Fig. 2 is front view before reamer uses;
Fig. 3 is the rear front view of wearing and tearing.
The specific embodiment
A kind of adjustable reamer as Figure 1-3, it is provided with a tapering screw 1; Described reamer 2 offers a taper hole 3 along axis, and described taper hole is provided with screw thread; Described tapering screw is provided with the screw thread that is complementary with taper hole, so that the tapering screw can screw in the taper hole 3; One or above equally distributed line of cut 4 are set between 2 liang of blades of described reamer, and described line of cut 4 is parallel to the reamer axis.
Be provided with scale on the described tapering screw.
Method of work:
As shown in Figure 1: in unworn situation, can directly use; As shown in Figure 2: after reamer used a period of time, experience wear and so that in the situation of size decreases, can be located at by rotation the tapering screw 1 of taper hole 3 so that tapering screw 1 can screw in the taper hole 3, thereby forced reamer 2 expansions and is adjusted to required size; Can be adjusted to required dimensional accuracy by the scale of adjusting on the tapering screw 1, need not to change reamer 2 again and make and tool rest is installed is broken down, impact is produced, and by reamer 2 sizes before obtaining wearing and tearing after regulating, can proceed processing.
This first novel goal of the invention is: realize need not the frequent reamer, need not frequently to proofread and correct the adjustable reamer that the reamer size just can be processed the different size engineering goods; More than be for preferred embodiment of the present utility model; the description that the utility model is carried out; those skilled in the art should do some suitable change within not breaking away from spirit and scope of the present utility model, it all belongs in the scope that the utility model appended claims asks for protection.
Claims (2)
