Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of grinding wheel finishing, in particular to a grinding wheel dresser. BACKGROUND

[0002] The grinding wheel of the steel ball grinding machine is generally provided with a grinding concave ring, and the grinding concave ring needs to be trimmed according to the final grinding requirement of the steel ball in the later period. The current operation mode is to use a diamond pen to move a track and trim the inner concave profile with a hyperbolic shape by inclining the track axis of the grinding wheel by a certain angle, so as to grind the concave raceway. This method is widely used in practice due to its simple structure.

[0003] The roller bearing raceway convexity grinding machine grinding wheel dresser disclosed in the patent application No. 201120324235.8 includes a base fixed on the trimming feed drag plate and a diamond pen for trimming the inner concave profile curve of the grinding wheel. The base is provided with a trimming reciprocating mechanism, and the trimming reciprocating mechanism drives the axial elastic moving element fixedly connected with the diamond pen to move back and forth. A small plunger pump valve combination element is installed on one side of the trimming reciprocating mechanism. The small plunger pump valve combination element generates displacement change by pressing the curve profile of the backup die fixed on the trimming feed drag plate. The hydraulic transmission drives the axial elastic moving element to drive the diamond pen to move, so that the diamond pen obtains the scaled-down moving track of the backup die profile curve, and the grinding wheel is trimmed to have the inner concave profile curve. However, the moving track of the die profile curve on the backup die in the structure is set unchanged, so the position of the backup die cannot be adjusted according to the actual situation of the grinding wheel, which leads to high final installation precision requirement, and therefore needs to be improved. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a grinding wheel dresser to solve the problem of the existing grinding wheel dresser that the moving track of the die profile curve cannot be adjusted after being set, which leads to high final installation precision requirement.

[0005] To achieve the above objectives, this utility model provides a grinding wheel dresser, including a base and a diamond pen for dressing the grinding wheel into a concave contour curve. The base is equipped with a dressing reciprocating mechanism, an axial elastic moving element fixedly fitted with the diamond pen, and a small plunger cylinder. The piston rod of the small plunger cylinder is connected to the side of the dressing reciprocating mechanism. The axial elastic moving element is disposed on the dressing reciprocating mechanism and reciprocates with it. The base is provided with a dressing template, the upper surface of which forms the diamond pen dressing contour path. One or more inner grooves are spaced apart on the diamond pen dressing contour path. One or more waist-shaped through holes are spaced apart on the dressing template, extending along the length of the dressing template. An adjusting bolt threaded to the base is inserted into each waist-shaped through hole. A dressing rod with a triangular structure is disposed on the back of the axial elastic moving element, and the dressing rod moves along the diamond pen dressing contour path as it reciprocates with the dressing reciprocating mechanism.

[0006] Preferably, for ease of movement, the trimming reciprocating mechanism includes a trapezoidal slide rail and a slide block located at the front end of the base. The back of the slide block is provided with a trapezoidal groove that is slidably connected to the trapezoidal slide rail. The front end of the slide block is provided with the axial elastic moving element. The small plunger cylinder is located on the side of the slide block, and the piston rod of the small plunger cylinder is connected to the side of the slide block.

[0007] Preferably, in order to facilitate the up-and-down movement of the axial elastic moving element, the front end of the slide is provided with a trapezoidal slide rail II extending along the height direction of the slide, the back of the axial elastic moving element is provided with a trapezoidal slide groove II that is slidably connected to the trapezoidal slide rail II, and a positioning seat is provided on the side of the slide, and a swing rod that limits the axial elastic moving element is hinged to the side of the positioning seat.

[0008] Preferably, to prevent the exposed trapezoidal slide rail from being exposed to the outside for a long time and thus getting dusty, affecting the movement of the slide block later, the side of the slide block away from the small plunger cylinder is hinged with two hinges to cover the exposed trapezoidal slide rail.

[0009] Preferably, for ease of disassembly, the output shaft of the small plunger cylinder is connected to an L-shaped support, which is connected to the side thread of the slide block by a fixing screw.

[0010] Preferably, in order to facilitate the installation of the entire dresser onto the grinding wheel bracket of the grinding machine, the back of the base is provided with a sloping bottom surface, and one or more locking bolts are provided on the sloping bottom surface.

[0011] As preferred, the upper side of the inclined bottom is fixed with an air path connector, the air path connector is communicated with the small plunger cylinder through an air pipe, and the air path connector is provided with a cylinder starting switch for driving the small plunger cylinder to be ventilated or cut off.

[0012] Compared with the prior art, the utility model has the advantages that because the waist type through hole is arranged on the trimming template, and the waist type through hole is connected with the base through the adjusting bolt, the horizontal position of the trimming template can be adjusted according to the installation requirement after the adjusting bolt is loosened, finally, the installation is more accurate, and the adjustment is relatively convenient.
