Abstract
The invention discloses a frock clamp, in particular to an adjustable rotary electrical-discharge machining frock clamp. The frock clamp comprises an upper connector (3) and a lower connector (6), wherein opposite concave pits are arranged at the center between the upper connector (3) and the lower connector (6); balls (4) are clamped in the concave pits; at least three adjustable bolts (5) distributed uniformly are arranged at the peripheries of the upper connector (3) and the lower connector (6); the upper end of an electrode installation sleeve (10) is clamped at the inner side of the lower connector (6); an adjustable top thread (8) pushing against the electrode installation sleeve (10) is arranged around the side edge of the lower connector (6); and the lower end of the electrode installation sleeve (10) is connected with a gland (11) by screw thread. When in installation, the frock clamp is fixed on a 3R frock clamp at the spindle head of a machine tool, and a round-bar electrode is installed at an inner taper hole of the electrode installation sleeve. After the round-bar electrode is installed, the angle and the relative position of the round-bar electrode can be adjusted, thereby improving the coaxiality of the round-bar electrode and a spindle and improving the machining accuracy.
Description
Technical field
The present invention relates to a kind of frock clamp, particularly a kind of adjustable rotary electrical-discharge machining frock clamp.
Background technology
When using the axial rotary processing goods of discharge lathe, circular rod electrode is to be installed on the machine tool chief axis through standard 3R frock clamp, and circular rod electrode is rotated with main shaft during work, and workpiece is carried out edm.Because the centering error can occur when circular rod electrode is installed, also there is mismachining tolerance in lathe itself, also there is axial error in the standard 3R frock clamp on the main tapping, can not circular rod electrode adjustment and main shaft is concentric, influence machining accuracy.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can adjust, improve the frock clamp of circular rod electrode and main shaft alignment, overcome the deficiency of prior art the circular rod electrode after installing.
Adjustable rotary electrical-discharge machining frock clamp of the present invention; Comprise connector 3 and following connector 6; The center is provided with relative pit and in pit, has clamped ball 4 between last connector 3 and following connector 6; The periphery of last connector 3 and following connector 6 is provided with equally distributed at least three adjustment bolts 5; The upper end clamping of electrode installation sleeve 10 is at the inboard of following connector 6 and around the side of following connector 6, be provided with the adjustment jackscrew 8 that leans electrode installation sleeve 10, and the lower end screw thread of electrode installation sleeve 10 is connected with pressure cap 11.
Adjustable rotary electrical-discharge machining frock clamp of the present invention is provided with packing ring 7 between the bottom surface of the end face of wherein said electrode installation sleeve 10 and following connector 6; Described adjustment jackscrew 8 be four and on the side of following connector 6 circumference evenly distribute.
Adjustable rotary electrical-discharge machining frock clamp of the present invention, during installation, this device is fixed on the 3R frock clamp at machine tool chief axis head place, and circular rod electrode is installed in the internal taper hole place of electrode installation sleeve.After circular rod electrode is installed, can adjust angle and relative position, improve the alignment of circular rod electrode and main shaft it, the raising degree machining accuracy.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 3 is last connector; 6 are following connector; The center is processed with relative pit between last connector 3 and following connector 6; In relative pit, clamped steel ball 4, the periphery of last connector 3 and following connector 6 is provided with equally distributed at least three (selecting four in this embodiment) adjustment bolts 5.
There are boss and clamping in the outside, the upper end of electrode installation sleeve 10 in the inboard of connector 6 down, and is spacing through gland 9, is connected for bolt between gland 9 and the following connector 6.Around the side of following connector 6, be provided with the adjustment jackscrew 8 that leans electrode installation sleeve 10, adjustment jackscrew 8 be four and on the side of connector 6 down circumference evenly distribute.The lower end screw thread of electrode installation sleeve 10 is connected with pressure cap 11.
Between the bottom surface of the end face of electrode installation sleeve 10 and following connector 6, be provided with packing ring 7.
Last connector top has installing plate 2 and bolt that top board 1 is arranged.
During installation, utilize installing plate 2 and top board 1 this device to be fixed on the 3R frock clamp at machine tool chief axis head place, circular rod electrode is installed in internal taper hole 8 places of electrode installation sleeve 10.The adjustment bolt 5 of connector 3 peripheries in the adjustment, making connector 3 is that fulcrum turns an angle with respect to following connector 6 with ball 4, the axial line that reaches electrode installation sleeve 10 is coaxial or parallel with the spindle axis line; If the axial line of electrode installation sleeve 10 and spindle axis line are in parastate, the adjustment jackscrew 8 of connector 6 peripheries under the adjustment moves electrode installation sleeve 10 in the horizontal direction again, and the axial line that reaches electrode installation sleeve 10 is coaxial with the axial line of main shaft.
