Thermal capacity etc..The basic configuration of brake drum is in drum type, as shown in figure 1, connecting hole 12 is provided with the installation end face 13 of brake drum 1,
It requires its big end endoporus 11, connecting hole 12 in process and installing end face 13 has axiality and perpendicularity formation tolerance will
Ask, therefore be accomplished by twice that clamping is processed respectively by traditional handicraft processing.It is present due to being secondary clamping, its axiality and
Perpendicularity it is difficult to ensure that, processing work efficiency is low, and labor intensity is big, in the big outer bowlder in end of clamping, the thick only 8.5mm of its arm, easily
Clamping deformation is produced, quality cannot be controlled effectively.
Utility model content
The purpose of this utility model is to provide a kind of clamping jaw for lathe process brake drum, reduction clamping centering
Number, improves processing efficiency and product quality, and reduce labor intensity.
To reach above-mentioned purpose, the utility model uses following technical scheme：
A kind of clamping jaw for lathe process brake drum, including the clamping jaw sheet triangular in shape on Lathe bench
Body, the clamping jaw body includes clamping jaw base and the jaw body located at clamping jaw base top, the clamping face of the jaw body be with
The arc shape that the outer wall of brake drum matches；Connected between the clamping jaw base and jaw body by connecting shaft；Positioned at jaw body
Outside connecting shaft screw top is connected with fastening ring, and the bottom of connecting shaft is fixed by rotation stop pin.
Further scheme, the bottom of the jaw body is located in the inside of clamping jaw base, and the bottom of the connecting shaft is worn
In the inside of jaw body, the top of connecting shaft is located at outside jaw body, and is fixed connecting shaft and jaw body by fastening ring.
Coordinate between further scheme, the inwall of the connecting shaft and jaw body for gap.
Offered on further scheme, the clamping jaw base and offer several and the pin in pin-and-hole, the jaw body
The through hole that hole is connected；The bottom of the rotation stop pin is sequentially passed through after the through hole on pin-and-hole and jaw body on clamping jaw base with connecting
Spindle is pushed against.
Further scheme, is provided with pad between the fastening ring and jaw body.
Clamping jaw of the present utility model is made up of the clamping jaw body triangular in shape on Lathe bench, passes through regulation
The level of jaw body in clamping jaw body with it is vertical, making its arc clamping face is matched with the outer wall of brake drum, and is clamped
Brake drum, to the big end endoporus of brake drum, connecting hole and installation end face while turnery processing, due to being not required to secondary clamping, is realized
Clamped one time is to complete all endoporus, the processing of end face；Clamping times are reduced, are reduced labor intensity, processing efficiency is improved.Together
When also assures that axiality and perpendicularity and element precision requirement.
In addition, the arc clamping face of jaw body is matched with the outer wall of brake drum, the cylindrical reducing of brake drum two is clamped
Place, due to being that face is contacted with face, increases clamping area, is minimized pinching deformation.
During regulation, unscrew fastening ring and rotation stop pin, can horizontally rotate or vertically move jaw body, when jaw body in place
Afterwards, first the bottom of rotation stop pin sequentially passed through after the through hole on pin-and-hole and jaw body on clamping jaw base and is pushed against with connecting shaft, footpath
To connecting shaft and jaw body is fixed, fastening ring is then screwed again and fixes connecting shaft and jaw body, so that jaw body be consolidated
It is fixed, realize the clamping to brake drum.Brake drum casting external diameter is compensate for due to the rotation of jaw body inconsistent, improve its adaptation
Property.
