Abstract

The utility model relates to a grinding tool for a centerless external circle of a shaft sleeve. The grinding tool comprises a dabber. Two ends of the dabber are respectively provided with a center hole. The grinding tool is characterized in that the dabber is provided with a first axis positioning part and a second axis positioning part; the dabber is orderly provided with a positioning flange, a positioning shaft segment, a transition shaft segment and a thread segment between the first axis positioning part and the second axis positioning part; a gland is sleeved on the transition shaft segment; and a locking nut is in a threaded connection on the thread segment. The grinding tool for centerless external circle of shaft sleeve is advantageous in that the shaft sleeve is sleeved on a positioning shaft segment of the dabber; one end of the shaft sleeve is tightly pushed against the positioning flange; the other end of the shaft sleeve is tightly pressed by the gland, so the shaft sleeve can be positioned via a dabber axis and a purpose of machining of a shaft sleeve type work piece on a common external circle grind is achieved; and with the dabber, deformation of a work piece caused by local pressure is avoided when the work piece is clamped by a three-paw chuck and a four-paw chuck, so effect on machining precision is prevented.

Description

Axle sleeve centerless external cylindrical grinder dress
Technical field
This patent belongs to the frock technical field of machining, particularly relates to a kind of axle sleeve centerless external cylindrical grinder dress.
Background technology
At present, for Model For The Bush-axle Type Parts, the method that production efficiency is higher is to adopt centreless grinding machine external to process.But for the enterprise that there is no centreless grinding machine external, because the rigidity of axle sleeve opposing radial load is poor, and because its hollow parts is larger, cannot use again the center of definite axle sleeve such as top grade, cannot use common cylindrical grinder to process.
Summary of the invention
This patent provides a kind of axle sleeve centerless external cylindrical grinder dress for solving the technical problem existing in known technology, and this frock can solve the peripheral milling processing problems of axle sleeve-like workpieces.
A kind of axle sleeve centerless external cylindrical grinder dress, comprise mandrel, described mandrel two ends are provided with centre bore, it is characterized in that: described mandrel has the first location division, axle center and the second location division, axle center, described mandrel is positioned to from the first axle center and between the second location division, axle center, is provided with successively locating flange, location shaft part, transition shaft part and thread segment, on transition shaft part, be set with gland, locking nut has been threaded on thread segment.
This patent can also be by the following technical solutions:
Preferably, described gland by round plate be sleeved on location grommet on axle head and that be fixedly connected with round plate and form.
Preferably, described location shaft part has a necking part.
Advantage and good effect that this patent has are:
Because this patent adopts technique scheme, by axle sleeve being sleeved on the location shaft part of mandrel, axle sleeve one end holds out against at locating flange simultaneously, and the other end is glanded compression, realize axle sleeve and utilized the location of mandrel axis, realized the object of on common cylindrical grinder machining shaft sleeve workpiece.In addition, when adopting mandrel also can avoid common three to grab chuck or chuck clamping work pieces, because local pressure causes workpiece deformation, affect the problem of machining accuracy.
Accompanying drawing explanation
Fig. 1 utilizes the be installed schematic diagram of axle sleeve of this patent embodiment 1;
Fig. 2 utilizes the be installed schematic diagram of axle sleeve of this patent embodiment 2;
Fig. 3 utilizes the be installed schematic diagram of axle sleeve of this patent embodiment 3.
In figure: 11, the first location division, axle center; 12, locating flange; 13, location shaft part; 14, transition shaft part; 15, thread segment; 16, the second location division, axle center; 2, locking nut; 3, gland; 31, grommet; 4, axle sleeve.
The specific embodiment
For further understanding utility model content, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Embodiment 1:
Refer to Fig. 1, a kind of axle sleeve centerless external cylindrical grinder dress, comprise mandrel, mandrel two ends are provided with centre bore, and mandrel has the first location division, axle center 11 and the second location division, axle center 16, and mandrel is positioned to from the first axle center and between the second location division, axle center, is provided with successively locating flange 12, location shaft part 13, transition shaft part 14 and thread segment 15, on transition shaft part, be set with gland 3, particularly, gland is one to be sleeved on the disk in transition axis section, and locking nut 2 has been threaded on thread segment.
The operating principle of the present embodiment is:
By axle sleeve being sleeved on the location shaft part of mandrel, axle sleeve one end holds out against at locating flange simultaneously, the other end is glanded compression, utilization location shaft part cylindrical coordinates with axle sleeve inner circle, realize axle sleeve and utilized the location of mandrel axis, then mandrel is installed on plain external grinding machine, utilizes the centre bore at mandrel two ends to position, realized the object of machining shaft sleeve workpiece on common cylindrical grinder.
Embodiment 2:
The difference of the present embodiment and embodiment 1 is, embodiment 1 is the axle sleeve for the normal length that is installed, for shorter axle sleeve, directly with discoid gland, cannot directly compress, so the present embodiment has increased by one section of grommet on discoid gland, grommet is fixedly connected with round plate, utilizes the end face of grommet to compress axle sleeve.
Embodiment 3:
The difference of the present embodiment and embodiment 1 is, embodiment 1 is the axle sleeve for the normal length that is installed, for longer axle sleeve, if the inner circle of axle sleeve has and coordinates on the length direction of location shaft part with the cylindrical of location shaft part, can cause so the fine finishining amount of location shaft part larger, improve mandrel processing cost.So the present embodiment is provided with a necking part at the location of axle sleeve shaft part, the larger excircle part at necking part two ends is carried out fine finishining, utilizes these two parts to coordinate with the inner circle of axle sleeve, to realize the location of axle sleeve.
Although by reference to the accompanying drawings the preferred embodiment of this patent is described above; but this patent is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not departing from the scope situation that this patent aim and claim protect, can also make a lot of forms, within these all belong to the protection domain of this patent.
