Abstract
The utility model discloses a copper bar wedge-caulking impact scudding knife in a motor rotor slot, comprising an impact head and a scudding knife. The scudding knife is embedded in a gripping head of the impact head so that the scudding knife is integrated with the gripping head into a whole, the end of the impact head is an end linked with a pneumatic tool, the knife edge of the scudding knife is of a circular arc shape, and the angle between two bevels of the knife edge is less than 50 DEG. The utility model is used for wedge-caulking a copper bar in the motor rotor slot, effectively solves the radial looseness of the copper bar in the motor rotor slot so that the electromagnetic force cannot cause the copper bar to radially vibrate in the slot, and evenly the motor runs for a long time, the copper bar cannot break down; and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of cutter, especially relate to a kind of with copper bar in the rotor groove, extrude, the rotor copper bar of wedging impacts and squeezes cutter.
Background technology
At present, use the copper bar squirrel cage rotor on motor, in order to adjusting startability, thereby improve the motor overall performance, reach the saving electric energy, raise the efficiency, purpose such as increase the service life.Each motor factory mainly uses is red copper row, adopts paint-dipping process after the manual wedging, and this technology has the following disadvantages: the one, and the rotor copper bar after the manual wedging has the reviewing phenomenon man-hour adding, and influences production efficiency; The 2nd,, the motor with this technology is made because electromagnetic force causes copper bar radially vibration in groove, behind the long-play, the copper bar fracture can occur, causes rotor not work.
The utility model content
The purpose of this utility model is to overcome the weak point that manual wedging rotor copper bar technology exists, and a kind of efficient height is provided, and the measured rotor buried copper row of wedging matter wedging is impacted and squeezed cutter.
The technical solution of the utility model is: it constitutes by impacting head and crowded cutter, squeezes cutter and embeds in the chuck that impacts head, and both are become one, and impacts head end to be and air tool union end, and the edge of a knife that squeezes cutter is a circular arc, and the angle on the edge of a knife two inclined-planes is less than 50 °.
Usage: after copper bar is squeezed into the electric machine rotor iron core groove, the impact head that squeezes cutter is impacted in the rotor buried copper row wedging of the utility model connect, impact rotor buried copper row, make buried copper row and rotor wedging with squeezing the cutter end with pneumatic tool.
Good effect of the present utility model: efficiently solve copper bar radially becoming flexible in the rotor groove, make electromagnetic force can not cause copper bar radially vibration in groove, motor long-play, copper bar can not rupture yet; The production efficiency height.
Description of drawings
Fig. 1 is the structural representation (front view) of the utility model one embodiment.
Fig. 2 is a left view embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2, present embodiment by impact 1 and crowded cutter 2 constitute, squeeze cutter 2 and embed and impact in 1 the chuck, both are become one, impact 1 outer end and be provided with and air tool connection port, the edge of a knife that squeezes cutter 2 is a circular arc, and the angle on the edge of a knife two inclined-planes is 30 °; Squeeze 20 millimeters of cutter 2 edge of a knife width, 12 millimeters of height.Squeezing cutter 2 makes for 9CrWMn forges the after-baking part.
Claims (2)
1, a kind of rotor buried copper row wedging is impacted and is squeezed cutter, it is characterized in that, constitutes by impacting head and crowded cutter, squeeze cutter and embed in the chuck that impacts head, both are become one, the impact head end is and air tool union end, the edge of a knife that squeezes cutter is a circular arc, and the angle on the edge of a knife two inclined-planes is less than 50 °.
2, a kind of rotor buried copper row as claimed in claim 1 wedging is impacted and is squeezed cutter, it is characterized in that, squeezes 20 millimeters of cutter edge of a knife width, 12 millimeters of height.
