Abstract
The utility model provides a reamer with a positioning step. The reamer is provided with a small-hole reamer blade and a large-hole reamer blade, wherein the small-hole reamer blade and the large-hole reamer blade form a step-type reamer head. The small-hole reamer blade and the large-hole reamer blade are arranged on the same reamer head to form the step-type reamer head. The modified step-type reamer can machine small holes and large holes in a valve plate at a time, is simple and convenient to operate, and saves time, and the machined valve plate is high in precision.
Description
Technical field
The utility model relates to reamer, relates in particular to a kind of reamer with the positioning table stepwise.
Background technology
Prior art when processing valve plate shown in Figure 4, is to cut with scissors aperture with aperture reamer shown in Figure 2 earlier, and macropore is cut with scissors with macropore reamer shown in Figure 3 in the back.Because workpiece is blank, uneven thickness is difficult to processing, so even if utilize graduation apparatus to process to reduce the tolerance degree of depth at drilling machine, the quality of product also is difficult to be guaranteed.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the purpose of this utility model provides a kind of simple in structure, easy and simple to handle and high band positioning table stepwise reamer of processing back product precision.
For achieving the above object, the technical solution of the utility model is:
A kind of reamer with the positioning table stepwise, reamer are provided with aperture reamer blade and macropore reamer blade, and aperture reamer blade and macropore reamer blade form a step reamer head.
A steel part positioning sleeve is set up in described reamer upper end.
Adopt such scheme, the utlity model has following usefulness:
Reamer of the present utility model is arranged on reamer sheet and big cutting blade on the reamer head simultaneously, form a step reamer head, the step reamer after the improvement can disposablely be finished the big aperture processing of valve plate, and is easy and simple to handle, save time, and the valve plate precision height after the processing.
The utility model is set up a steel part positioning sleeve in the reamer upper end, when positioning sleeve contacts with the foundry goods workpiece planarization, illustrates that the degree of depth puts in place, the valve plate steady quality that processes like this, and speed is also fast.
Below in conjunction with accompanying drawing and body embodiment thereof the utility model is described in further detail.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of existing aperture reamer;
Fig. 3 is the structural representation of existing macropore reamer;
Fig. 4 is the structural representation of valve plate.
Wherein, 1, aperture reamer blade 2, macropore reamer blade 3, steel part positioning sleeve.
The specific embodiment
Referring to a kind of reamer with the positioning table stepwise shown in Figure 1, reamer is provided with aperture reamer blade 1 and macropore reamer blade 2, and aperture reamer blade 1 and macropore reamer blade form a step reamer head, and a steel part positioning sleeve 3 is also set up in the reamer upper end.
The utility model is arranged on reamer sheet 1 and big cutting blade 2 on the reamer head simultaneously, forms a step reamer head, and the step reamer after the improvement can disposablely be finished the big aperture processing of valve plate, and is easy and simple to handle, save time, and the valve plate precision height after the processing; Also set up a steel part positioning sleeve 3 in the reamer upper end, when steel part positioning sleeve 3 contacts with the foundry goods workpiece planarization, illustrate that the degree of depth puts in place, the valve plate steady quality that processes like this, speed is also fast.
