Abstract

The utility model relates to a pin joint structure for a grinding wheel dresser of a grinding machine, which is composed of a base and a dressing tool apron. One end surface of the dressing tool apron is spliced with the base, and a pin joint structure is formed on one end of the splicing surface. The dressing tool apron can be lifted off from the base by the pin joint position. Both sides of the base which is correspondingly connected with the dressing tool apron of the utility model are convexly provided with buckling ears which are provided with through holes in the center of side surfaces. The buckling ears are provided with spiral locking slits which pass through the through holes. Both sides of the dressing tool apron are provided with pin joint shafts which are matched with the through holes at the position corresponding to the buckling ears of the pin joint base. The contact surfaces of the circular through holes and the pin joint shafts are arc surface, so the contact area is larger than a general pin joint wire, the stress dispersing of the pin joint shafts is raised, and the grinding process precision is raised.

Description

The joint structure of grinder wheel trimming device

The utility model relates to grinder wheel trimming device, refers in particular to a kind of joint structure of grinder wheel trimming device.

As everyone knows, grinding machine must keep quite high precision, could guarantee that machined object has higher precision, therefore must rebuild device with grinder wheel grinder wheel is repaired, to guarantee that emery wheel has higher processing precision, grinder wheel trimming device commonly used is divided into two big classes substantially:

The first kind is the grinding machine wheel trimming device of vertically cutting, as Fig. 1-shown in Figure 2, mainly comprise pedestal 10 and splice with it repair tool rest 20, the whole tool rest 20 of repairing holds part 22 by the upper saddle 21 and the end and is constituted, hold on the face that splices of part 22 and upper saddle 21 at this end, system forms with the structure fit of dovetail slide, slip in one and install pad 27, hold difference secure bond front and back, two ends, the below circular rod member 23 and 24 that part 22 shrinks the end of in, and hold part 22 at the bottom of passing pedestal 10 interlockings with a bolt 25, forming pin-jointed structure, when desire is adjusted different finishing angles, circular rod member 24 after repairing tool rest 20 can be the center, turn pulls open the distance with pedestal 10, makes to repair tool rest 20 and be oblique and put, and places slip gauge 26 in the bottom of preceding circular rod member 23, adjusted the reconditioning gradient of repairing cutter, its major defect is:

1, owing to repaiies tool rest 20 and pedestal 10 with bolt 25 combinations, circular rod member 24 is the center after repairing tool rest 20, turn pull open with pedestal 10 apart from the time, because circular rod member 24 activities in back bear in the default V-shaped groove 11 in pedestal 10 surfaces, when as long as it lifted the gradient of predetermined permission, back round bar spare 24 promptly is subjected to the body card of stumbling, and can't wide-angle revolves to open, and makes its angle to the emery wheel trimming limited.

2, the back round bar spare 24 of repairing tool rest 20 is with free state activity bearing with pedestal 10, make it not have good operational stability, and the set-up mode of free bearing, make back round bar spare 24 only have two lines to contact with splicing of V-shaped groove 11, be easy to generate concentrated stress and wear and tear, have influence on the processing precise degree.

3, pedestal 10 and repair the pad that 20 folders of tool rest are established after long-term use, can wear away and influences machining accuracy, and must be renewed, and renews in the pad operation consuming time bothersome.

Second class is the grinder wheel trimming device of the flat cutting of crouching, as shown in Figure 3-Figure 5, mainly by pedestal 30, repair tool rest 40, one group of guide rail 50, fixedly spiral shell group 60, helical 70 and axis of rotation sleeve 80 are formed, repairing tool rest 40 is locked on axle center 41 with screw 70 and is inserted in axis of rotation sleeve 80 again, be locked in again on the pedestal 30, make repair tool rest 40 according to axle center 41 for the center turns to lift, its major defect is:

1, owing to must unclamp the fixedly spiral shell group 60 of both sides, could will repair tool rest 40 and lift required angle, and carry out the adjustment of angle, and then insert slip gauge, fixedly spiral shell group 60 locks one by one again, makes to adjust the inconvenience of formality trouble.

2, when lifting the adjustment of opening angle, fixedly the opportunity and the screw lock strength number of 60 lockings of spiral shell group must get by experience, and be inconsistent as the screw lock strength at two ends, easily makes to repair tool rest 40 generation angular deviations.

The purpose of this utility model is to provide a kind of joint structure of follow-on grinder wheel trimming device, establish the buckle ear of circular hole thoroughly in the both sides raised side central authorities that tool rest is repaiied in the corresponding connection of pedestal, and on buckle ear, offer the screw lock crack of sensible this circular hole, this repaiies the corresponding pedestal place that articulates, tool rest both sides, protrude the drive-connecting shaft that is nested and joins with circular hole, overcome the drawback of prior art, reach and improve the purpose that the stress that articulates disperses and improve grinding accuracy.

Order of the present utility model is achieved in that the joint structure of a kind of grinder wheel trimming device, and by pedestal and repair tool rest and constitute, this end face of repairing tool rest pedestal that splices forms joint structure in an end of the face of splicing, and this repaiies tool rest can lift off pedestal from the articulated section; This joint structure is positioned at the corresponding both sides of repairing tool rest that connect of pedestal and is convexly equipped with the buckle ear that side central authorities are provided with open-work, offers the screw lock crack of sensible open-work on this buckle ear, and this corresponding buckle ear that articulates pedestal in both sides of repairing tool rest is provided with the drive-connecting shaft that is nested and joins with open-work; The one of holding in addition that this pedestal is corresponding with joint structure is bent into the intersection point piece; This is repaiied tool rest and holds part by upper saddle, flat plate and the end and constitute, hold part and slip combination with monolateral inclined-plane grooved rail at this upward-sliding piece and the end, and its other face is whittled into vertical surface respectively, and the flat plate of splicing, by screw this flat plate is fixed at upper saddle, the top of this upward-sliding piece is arranged with for repairing the embedding hole that cutter inserts; This buckle ear by opening towards the U-shaped pedestal of repairing tool rest, screw lock cap seal one briquetting and getting, directly with the U-shaped imploded arcs wall of this U-shaped pedestal as circular hole, and the seam between this briquetting and U-shaped pedestal, just in time form above-mentioned screw lock crack, on briquetting and U-shaped pedestal, form the screw that runs through that screw lock is adjusted screw and fixed screw.

Major advantage of the present utility model is:

1, because circular hole and drive-connecting shaft are arc contact surface, bigger than the contact of pivot joint line commonly used, the stress that improves pivot disperses and the raising grinding accuracy.

2, slip combination because part is held at the upward-sliding piece and the end with monolateral inclined-plane grooved rail, face is the vertical surface and the flat plate of splicing in addition, after the long-term use wearing and tearing, directly repairs flat plate and can continue to use, and overcomes the drawback of upgrading solid shim.

When 3, being used for the grinder wheel trimming device of the flat cutting of crouching, because joint structure,, overcome the trouble and the inconsistent drawback of screw lock strength of angle adjustment, improved machining accuracy without guide rail and fixing member such as spiral shell group.
