Abstract
The utility model discloses a reamer for processing automobile oil pump parts which comprises a cutter arbor. Two cutting blades are respectively arranged at the front end and in the middle of the cutter arbor, the two adjacent cutting blades are arranged symmetrically, straight lines where the cutting edges of the two adjacent cutting blades are positioned are parallel with each other, the vertical distance between the two cutting edges is 0.4mm, and the length of the cutting ligament at the outer edge of each cutting edge is 0.4mm. The reamer has the benefits of reasonable design and simple structure, is mainly used for processing automobile oil pump parts, and has large cutting force and high reaming spped in the manufacturing process; and vertical vibration marks no longer appear on the hole walls of the processed parts, so that the quality of the products is fully upgraded, and both favorable economic benefit and social benefit are brought to enterprises.
Description
Technical field
The utility model belongs to the Machining Technology field, relates in particular to a kind of reamer that is used for processing automobile oil pump part.
Background technology
In the last few years, along with development of science and technology, machinery manufacturing industry also is more and more higher to the requirement of machining accuracy, and reamer is as a kind of machining cutter commonly used, its structure is not only determining intensity, the service life of self, is more determining to cut with scissors out the error size and the precision height of workpiece hole.At present, the reamer that the automobile fuel pump part is reamed is the twolip structure, and knife bar front end and middle part are respectively equipped with two cutting tips, because the hole in piece part of processing is darker, the characteristics of deep hole machining require that bigger cutting force will be arranged, and cutting speed is had relatively high expectations.And the cutting edge of adjacent two cutting tips of existing reamer is symmetrical arranged and be positioned on same the straight line of crossing the knife bar center, causes in process cutting force less; In addition, the cutting land at the cutting tip outer rim place of existing this reamer is shorter, has only 0.2mm, and the chatter mark of vertical direction often appears in part hole wall position in the process, influences product quality, does not reach designing requirement.Therefore, the structure of this reamer is needed improvement badly.
The utility model content
The utility model provides the reamer that is used for processing automobile oil pump part that a kind of cutting force is big, the processing parts endoporus does not have chatter mark in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the reamer that is used for processing automobile oil pump part, comprise knife bar, knife bar front end and middle part are respectively equipped with two cutting tips, adjacent two cutting tips are symmetrical arranged, the straight line parallel setting at the cutting edge place of described adjacent two cutting tips, the vertical range between two cutting edges are 0.4mm.
The cutting ligament length at described cutting edge outer rim place is 0.4mm.
Adopt said structure, the beneficial effect that reaches has:
1, the straight line parallel setting at the cutting edge place of adjacent two cutting tips, the vertical range between two cutting edges is 0.4mm; This structure cutting force in process that can heighten, and correspondingly improve cutting speed.
2, the cutting ligament length at cutting edge outer rim place is 0.4mm, and this structure makes that the chatter mark of vertical direction no longer appears in part hole wall position in the process, thereby promotes product quality, reaches designing requirement.
The utility model is reasonable in design, simple in structure, be mainly used in the processing operation of automobile fuel pump hole in piece part, cutting force is big in the process, fraising speed height, the chatter mark of vertical direction no longer appears in the part hole wall that processes, fully promote the better quality of product, for enterprise creates good economic benefit and social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that enlarged drawing is looked on the left side in cross section, adjacent two cutting tip places in the middle of the utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, the reamer that is used for processing automobile oil pump part of the present utility model, comprise knife bar 1, knife bar 1 front end is provided with two symmetrically arranged cutting tips 2, knife bar 1 middle part is provided with two symmetrically arranged cutting tips 3, two cutting tip 3 residing external diameters are greater than two cutting tips, 2 residing external diameters, like this can be so that cutting tip 2 and cutting tip 3 have certain processing capacity respectively, the straight line parallel setting at two cutting edges, 4 places of two cutting tips 2 or two cutting tips 3, vertical range A between two cutting edges 4 is 0.4mm, and promptly each cutting edge 4 is 0.2mm to the lateral separation B of knife bar 1 cross centre line.Cutting ligament 5 length C at two cutting edges, 4 outer rim places are 0.4mm.Cutting tip 2 and cutting tip 3 are prior art, and concrete structure repeats no more.
The utility model is mainly used in the processing operation of automobile fuel pump hole in piece part, and cutting force is big in the process, fraising speed height, and the chatter mark of vertical direction no longer appears in the part hole wall that processes, and reaches designing requirement, fully promotes the better quality of product.
Claims (2)
1. the reamer that is used for processing automobile oil pump part, comprise knife bar, knife bar front end and middle part are respectively equipped with two cutting tips, adjacent two cutting tips are symmetrical arranged, it is characterized in that: the straight line parallel setting at the cutting edge place of described adjacent two cutting tips, the vertical range between two cutting edges are 0.4mm.
2. the reamer that is used for processing automobile oil pump part according to claim 1 is characterized in that: the cutting ligament length at described cutting edge outer rim place is 0.4mm.
