Referring to fig. 1 to 4, the present invention provides a numerical control gear grinding machine tool, which includes:
the lathe comprises a lathe bed 100, wherein the lathe bed 100 is provided with a first vertical beam 101, a second vertical beam 103 and a cross beam 102 erected on the first vertical beam 101 and the second vertical beam 103, the cross beam 102 is provided with a plurality of X-axis guide rails 106 extending along the horizontal X-axis direction, and at least one X-axis guide rail 106 is distributed on the horizontal plane of the cross beam 102;
a first mounting seat 200 slidably disposed on the X-axis guide rail 106;
a grinding wheel box 201 which is rotatably arranged on the first mounting base 200 around a vertical rotating shaft B axis;
the grinding wheel spindle C shaft is arranged in the grinding wheel box body 201 along the direction vertical to the rotating shaft B shaft;
the second mounting seat 301 is movably arranged on the side surface, close to the second vertical beam 103, of the first vertical beam 101 along the vertical Y-axis direction;
a workpiece box 300 movably arranged on the second mounting base 301 along the horizontal Z-axis direction;
the workpiece spindle a axis is disposed in the workpiece box 300 in a direction parallel to the Z axis.
By adopting the numerical control gear grinding machine tool with the structure, X, Y, Z three-axis movement adjustment can be realized between the A shaft of the workpiece main shaft and the C shaft of the grinding wheel main shaft, the angle adjustment between the A shaft of the workpiece main shaft and the C shaft of the grinding wheel main shaft can be realized through the B shaft of the revolving shaft, and the processing function of the traditional machine tool can be realized. In addition, the X-axis guide rail 106 for mounting the first mounting base 200 is positioned on the horizontal plane of the cross beam 102, so that compared with the traditional machine tool structure, the numerical control gear grinding machine tool can effectively reduce the strength requirement of the X-axis guide rail 106, is beneficial to reducing the production cost and improving the transmission stability. And the at least one X-axis guide rail 106 is arranged at the level of the cross beam 102, which is also beneficial to improving the assembly efficiency of the first mounting seat 200.
Referring to fig. 1 to 3, in some embodiments of the present invention, one side of the upper end surface of the beam 102 is depressed to form a first step 104, and X-axis guide rails 106 are disposed on the upper end surface and the outer side surface of the first step 104. Correspondingly, the first mounting seat 200 is located at the side of the beam 102, and the first mounting seat 200 has a convex portion adapted to the first step 104.
In the present embodiment, the first step 104 formed by sinking can reduce the overall height of the first mounting seat 200 mounted on the cross beam 102, which is beneficial to improve the integrity of the machine tool, and can achieve weight reduction to some extent. The sinking depth of the first step 104 can be set according to the actual size of the cross beam 102, and can be flexibly set on the premise of ensuring the strength and rigidity requirements of the cross beam 102, which is not specifically described herein.
In some embodiments of the present invention, the first vertical beam 101 is provided with a Y-axis guide 107 at a side close to and adjacent to the side of the second vertical beam 103, and the second mounting seat 301 is slidably disposed on the Y-axis guide 107. Because the side that first perpendicular roof beam 101 is close to second perpendicular roof beam 103 is sheltered from by second perpendicular roof beam 103, consequently if Y axle guide rail 107 all set up when this side can't avoid receiving the influence that second perpendicular roof beam 103 sheltered from, and in this embodiment through with some Y axle guide rail 107 set up with just on the side that second perpendicular roof beam 103 is adjacent, can effectively weaken this kind of influence, promote the packaging efficiency of second mount pad 301. In this embodiment, the side surface adjacent to the second vertical beam 103 may be the side surface of the first vertical beam 101 close to the grinding wheel box 201, or the side surface far from the grinding wheel box 201.
In some embodiments of the present invention, the side surface of the first vertical beam 101 close to the second vertical beam 103 is provided with a second step 105 formed by recessing and extending along the Y-axis direction at one end close to the grinding wheel box 201, and the Y-axis guide rail 107 is provided at the end surface of the second step 105 facing the grinding wheel box 201 and the end surface facing the second vertical beam 103.
As can be seen with reference to fig. 1, the cross beam 102, the first vertical beam 101 and the second vertical beam 103 are kept flush near the end face of the grinding wheel box 201, according to a design conventional in the industry. Therefore, in the embodiment of the present invention, the structure design of the second step 105 is formed by recessing, and more directly, the Y-axis guide rail 107 is disposed on the side surface of the first vertical beam 101 close to the grinding wheel box 201, the latter needs to extend outward through the first mounting seat 200 to ensure that a sufficient space is reserved between the grinding wheel box 201 and the first vertical beam 101 along the Z-axis direction, so that the overall moment of the first mounting seat 200 and the grinding wheel box 201 relative to the cross beam 102 is relatively large, and the former can effectively shorten the distance from the C-axis of the grinding wheel spindle to the end surface of the cross beam 102, thereby reducing the moment, and improving the transmission stability and accuracy of the grinding wheel box 201 and the first mounting seat 200.
On the basis of the foregoing embodiments, in some embodiments of the present invention, the Y-axis guide rail 107 provided on the end surface of the second step 105 near the second vertical beam 103 is located at the edge of the region where the second vertical beam 103 faces the second step 105 or outside the region where the second vertical beam 103 faces the second step 105. In this way, the Y-axis guide rail 107 is provided at the edge or the outer side of the region directly opposite to the second vertical beam 103, so that the influence of the second vertical beam 103 can be effectively reduced, and the assembly efficiency of the second mounting base 301 can be improved.
Obviously, the above-mentioned position arrangement can be adopted to reduce or eliminate the influence of the second vertical beam 103 when the second step 105 is not provided.
In some embodiments of the invention, the first mount 200 is provided with a first relief cavity into which the wheel housing 201 partially fits, the second mount 301 is provided with a second relief cavity into which the workpiece housing 300 partially fits. Therefore, the length of the corresponding force arm can be effectively reduced through the yielding concave cavity, the transmission stability is favorably improved, and the performance requirement on the corresponding guide rail is reduced.
In some embodiments of the present invention, the first and second mounting seats 200 and 301 are provided with a reinforcing structure corresponding to the first and second yield cavities, respectively. The reinforcing structure can be arranged in the first yielding cavity and the second yielding cavity and can also be arranged outside the first yielding cavity and the second yielding cavity. The reinforcing structure may be a reinforcing rib plate, a reinforcing rib, or the like, and is not particularly limited herein. Numerical control gear grinding machine tool in this embodiment can effectively promote the structural strength of first mount pad 200, second mount pad 301 through additional strengthening, and then is favorable to ensureing transmission stability, also can promote the bearing machining ability of lathe simultaneously.
According to some embodiments of the present invention, a wheel dresser is provided on the workpiece box 300, and the wheel dresser dresses a wheel. Referring to fig. 1, a rotating shaft of a dresser is arranged parallel to an a-axis of a workpiece spindle.
