A kind of anchor clamps that are used for the motor housing metalworking
Technical field
Anchor clamps when the utility model relates to a kind of motor component metalworking particularly relate to a kind of anchor clamps when being used for the motor housing metalworking.
Background technology
The prior motor shell is formed by iron casting usually, and the shell blank needs could use after carrying out metalworking on the lathe.When prior motor shell blank carries out metalworking on lathe, clamp the outer wall of motor housing blank earlier with the scroll chuck on the lathe, inwall and one of them end face to the motor housing blank carry out turning processing, but need leave certain chipping allowance, pulling down from the scroll chuck of lathe carrying out fine finishining motor housing blank then, an end face that carries out turning processing is clamped in the motor housing blank on the scroll chuck inwardly again, another end face to the motor housing blank carries out machining, simultaneously, the inwall of motor housing blank is carried out machining to given size.
Adopt this mode that the motor housing blank is carried out metalworking, owing to need the motor housing blank is carried out secondary clamping at least, increased on the one hand the operation when the motor housing blank carried out metalworking, on the other hand, because multiple clamping, make two end faces of motor housing that process and the center of inwall have the clamping error, influenced the precision and the quality of whole motor.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide clamping of a kind of need just can finish the anchor clamps that the motor housing blank carried out metalworking.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anchor clamps that are used for the motor housing metalworking, comprise chuck and three clamp bodies, described chuck is provided with chuck and leads and roll, an end face of described clamp body is provided with to lead with chuck and rolls the anchor clamps that are complementary and lead and roll, described three clamp bodies are 120 degree and are installed on the chuck with one heart, described three anchor clamps physical efficiencys are led along chuck and are rolled synchronous normal direction and move, described clamp body is led the end that rolls away from anchor clamps and is provided with clamp head, described clamp head is provided with clamping face and withdrawing face at the chuck axis direction, described clamping face greater than the distance of withdrawing face from the chuck axis, is provided with retaining face between described clamping face and the withdrawing face from the distance of chuck axis.
Described clamping face is the 2-20 millimeter from the distance and the withdrawing face of chuck axis from the range difference of chuck axis.
The length of described withdrawing face is 2-15 centimetre.
The anchor clamps that are used for the motor housing metalworking of the present utility model have been adopted, when the motor housing blank is carried out metalworking, only need the motor installation foot on the motor housing blank is clamped on the clamping face of anchor clamps, can carry out metalworking to two end faces and the inwall of motor housing, guarantee the concentricity of two end faces and the inwall of motor housing, and then guaranteed the quality and the precision of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Among the figure: the 1-chuck, the 2-clamp body, the 3-clamp head, the 4-clamping face, 5-retaining face, the 6-motor housing, 7-withdrawing face, 8-chuck axis, 9-motor installation foot, the 11-chuck is led and is rolled, and the 21-anchor clamps are led and are rolled.
The specific embodiment
As depicted in figs. 1 and 2, the utility model discloses a kind of anchor clamps that are used for the motor housing metalworking, comprise chuck (1) and three clamp bodies (2), described chuck (1) is provided with chuck and leads and roll (11), an end face of described clamp body (2) is provided with to lead with chuck and rolls anchor clamps that (11) be complementary and lead and roll (21), described three clamp bodies (2) are 120 degree and are installed in one heart on the chuck (1), described three clamp bodies (2) can lead along chuck roll (11) synchronously normal direction move, described clamp body (2) is led the end that rolls (21) away from anchor clamps and is provided with clamp head (3), described clamp head (3) is provided with clamping face (4) and withdrawing face (7) in chuck axis (8) direction, described clamping face (4) greater than the distance of withdrawing face (7) from chuck axis (8), is provided with retaining face (5) between described clamping face (4) and the withdrawing face (7) from the distance of chuck axis (8).
When motor housing (6) blank is carried out metalworking, the distance of elder generation's adjustable clamp concrete (2) and chuck axis (8), concrete control method is the same with scroll chuck control method on the engine lathe, here do not remake and be described in detail, make the motor installation foot (9) on the motor housing (6) be clamped in upward locking of clamping face (4), can carry out metalworking to two end faces and the inwall of motor housing (6), maximum characteristics of the present utility model are the withdrawing faces (7) that are provided with on clamp head (3), adopt suitable cutter under the situation of uncomfortable rotating motor shell (6), can carry out metalworking to the end face of close chuck (1) one end of motor housing (6).Guarantee the concentricity of two end faces and the inwall of motor housing (6), and then guaranteed the quality and the precision of motor.
Described clamping face (4) is the 2-20 millimeter from the distance and the withdrawing face (7) of chuck axis (8) from the range difference of chuck axis (8).The length of described withdrawing face (7) is 2-15 centimetre.Concrete size Selection can be adjusted according to the size of motor housing (6) blank of need processing, for the less motor housing of size (6) blank, can select less clamping face (4) from the distance of chuck axis (8) and withdrawing face (7) from the range difference of chuck axis (8) and less withdrawing face (7) length, for larger-size motor housing (6) blank, can select bigger clamping face (4) from the distance of chuck axis (8) and withdrawing face (7) from the range difference of chuck axis (8) and bigger withdrawing face (7) length.
