On the other hand, grinding machine 2 also comprises exit chute 310, base circle 500 unloading one by one herein.In exit chute 300, base circle 500 is moved by the direction of gravity in arrow A 310.In the side towards arm 200, exit chute 310 is equipped with release 312, this release 312 is provided with the recess 314 that size is enough to the clamping device of holding mobile arm 200, but lateral dimension measured between the both sides of the edge of this recess is less than the external diameter of circle 500.
In the configuration of Fig. 1 to Fig. 5, use new emery wheel 6 and its diameter D6 is approximately 610mm.
Nozzle 150 sprays the cooling fluid of the such as water of specified rate for the contact surface place between outer peripheral face 10 and outer peripheral face 502, that is, the contact area between emery wheel 6 and race ring 500 is arranged in work station 14.
When emery wheel 6 has the maximum diameter as shown in Fig. 1 to Fig. 5, nozzle 150 must be spaced apart with axis X 6, and this distance is enough large to avoid the contact between element 6 and element 150.On the other hand, when the almost wearing and tearing of emery wheel 6 as shown in Fig. 6 and Fig. 7, nozzle 150 must be enough near with the contact area effectively cooling outer peripheral face 10 and the outer peripheral face 502 of circle 500 with outer peripheral face 10.
In order to adjust the radial distance between axis X 6 and nozzle 150, this nozzle is connected to slide block 152, this slide block 152 can move along the axis Y154 perpendicular to axis X 6, and is limited by the guide rail 154 be arranged in supporting construction that two gripper shoes 156 and 158 are formed.These two gripper shoes move together with auxiliary framework 7, and auxiliary framework 7 supports pulley 6.
On the other hand, knobs 12 by comprising bracket 162, the supporting construction of gripper shoe 164 and pole 166 supports.This supporting construction hangs down from polishing slide block 170, and this polishing slide block 170 is arranged in gripper shoe 158, and polishing slide block 170 has along the possibility perpendicular to the axis Y170 translation of axis X 6.When the outer peripheral face of knobs 12 for the pulley 6 that is shaped, knobs 12 is against the outer surface of emery wheel 6, and the position of now polishing slide block automatically adjusts along axis Y170, and this position is as the function of the diameter D6 of emery wheel 6.
On the other hand, bar 172 is slidably mounted in the parallelepiped housing 174 that is fixed in gripper shoe 156.One end 176 of bar 172 is provided with screw 178, its head 180 against polishing slide block 170 front surface 182, this front surface 182 vertical axis Y170.Spring 184 is installed around bar 172 and is compressed between housing 174 and the packing ring 186 being fixedly mounted in end 176.Due to this structure, the polishing slide block 170 reduced corresponding to diameter D6 is sent to the bar slided in housing 174, this is because front surface 182 promotes head 180 to the movement on the left side of Fig. 1 and Fig. 2.On the other hand, if polishing slide block 170 moves to the right of Fig. 1 and Fig. 2, when particularly being replaced with by the pulley 6 of wearing and tearing new, spring 184 promotes packing ring 186 and bar 172 towards the direction of front surface 182.In other words, spring 184 ensure that the durable contact between head 180 and front surface 182.
Bar 190 is hinged in gripper shoe 156 around the axis X 190 of the X6 that parallels to the axis.Two arms 192 and 194 that this bar is extended by two radial direction relative to axis X 190 are formed.
First longitudinal slit 196 is arranged on the first arm 192 and second longitudinal slit 198 is arranged on the second arm 194.The longitudinal direction of each slit processed in arm is parallel to the longitudinal direction of arm, that is, the radial direction of axial X190.
The pin 202 be arranged on slide block 152 is bonded in the first slit 196.Therefore, the first arm 192 is hinged on the first slide block 152 around the longitudinal axis X202 of pin 202.
On the other hand, pin 204 is through bar 172 and the both sides being formed at housing 174 and two of the Y170 that parallels to the axis longitudinal slit 174A and 174B.Pin 204 is also engaged in the second slit 198, so that the second arm 194 is hinged on bar 172 around the central axis X 204 of the pin 204 of the X6 that parallels to the axis.
D1 represents the distance relative to axis X 190 radial measurement between axis X 190 and axis X 202.On the other hand, d2 represents the distance relative to axis X 190 radial measurement between axis X 190 and axis X 204.Distance d1 and d2 is equal.Therefore, if bar 190 rotates around axis X 190, pin 202 is equal along the amplitude of the axial displacement of axis Y170 with pin 204 along the axial displacement of axis Y154.
High-visible from Fig. 3, slide block 152 is connected to nozzle 150 by hollow tube 210.This pipe 210 is in a cantilever fashion relative to slide block 152 support nozzle 150.This allow under the pressure of about 3bars via hollow tube 210 by water supply nozzle 150.At the opposite side of nozzle 150, slide block 152 is provided with the joint 212 for connecting cooling fluid inlet tube 214, and wherein water circulates under pressure, as shown in the arrow A 1 in Fig. 3.Joint 212 is connected to pipe 210 by the unmarked passage of slide block 152 inside.The flow velocity of water in the inner passage of pipe 214 and 210 and slide block 152 can be selected, be approximately 80m/s to make the speed of the water of ejection from nozzle 150 as indicated by arrow a 2.This speed is constant, has nothing to do with the size of emery wheel 6, and this is because the outlet opening of nozzle 150 does not change, because do not occur directly to contact between element 6 with element 150.
When filling new emery wheel 6 on grinding machine 2, knobs 12 must be removed from work station 14, and this causes the translational motion on the direction of polishing slide block 170 arrow A 3 in the diagram.Therefore, polish slide block 170 and leave housing 174.This motion causes spring 184 to promote packing ring 186 to leave housing 174, this causes the bar 190 in the configuration of Fig. 3 and Fig. 5, wherein pin 204 is near the first end 174B1 towards polishing slide block 170 of slit 174B, and shifts slide block 152 onto position away from axis X 6.
When using grinding machine 2, emery wheel 6 must regularly be reinvented via knobs, and this causes the reduction of diameter.Therefore, knobs 12 is shifted to closer to the position in axis X 6, and this causes polishing slide block 170 along the translational motion of axis Y170 in arrow A 4 direction.This translational motion causes catch bar 172 in housing 174 and causes pin 204 to be removed from the first end 174B1 of slit 174B.Pin 204 causes bar 190 around the rotary motion in axis X 190 arrow R1 direction in Figure 5 along the axially-movable of axis Y170.During this rotary motion of bar 190, pin 202 and 204 moves towards axis X 190 in slit 196 and 198, subsequently on the contrary.When emery wheel 6 almost weares and teares completely, reach the configuration of Fig. 6 and Fig. 7, wherein axis X 204 is near the second end 174B2 away from polishing slide block 170 of slit 174B, and slide block 152 moves to the position closer to axis X 6 along axis Y154.
Thus, due to by polishing slide block 170 and nozzle 150 between element 152,172,190,202, and 204 formed mechanical linkage, especially due to the use of bar 190, the position as the nozzle 150 of the function of the outer diameter D 6 of emery wheel 6 automatically regulates.Carry out moving nozzle 150 without any need for peripheral driver, and the replacement time of nozzle 150 and preset time are cancelled, because when new emery wheel 6 loaded onto by grinding machine 2, automatic calibration knobs 12 is to the location of the position movement away from axis X 6.
Spring 184 is acting on packing ring 186 towards the elastic acting force in ground smooth block 170 direction, and this tends to the configuration carriage release lever 190 towards Fig. 1 to Fig. 5, and tends to keep nozzle 150 to leave emery wheel 6.
According to the bright unshowned embodiment of this law, bar 190 and slide block 152 and the linkwork between bar 190 and bar 174 can be put upside down.Pin can be arranged on bar, and the slit of correspondence can be arranged on element 152 and 174.
