Abstract
The utility model discloses a grinding disc structure of a double-end-surface grinding machine. The grinding disc structure comprises a base, a motor, a drive mechanism, a grinding wheel group and a grinding disc; the motor is connected with the grinding disc in a linkage way through the drive mechanism; the drive mechanism comprises a triangle belt pulley A, a triangle belt pulley B and a triangle belt; and three belt pulley grooves with different radiuses are arranged on the triangle belt pulley A. The grinding precision on a spring is improved; once the spring is clamped due to an accident, the grinding disc can automatically stop; and furthermore, the structure is simple.
Description
Technical field
The present invention relates to the Metal Cutting Machine Tool field, particularly double-ended grinding machine mill structure.
Background technology
Spring is the part of our daily life, Compress Spring is the grinding that needs by to both ends of the surface generally speaking, make the end face of bearing coil keep good contacting with its part that matches, reach perpendicularity, height and roughness that spring needs, guaranteeing the performance requirement of parts or main frame, the cross grinding manufacturing procedure of spring is called the mill spring.Two kinds in general minute horizontal reed milling machine and vertical mill spring machine, most spring manufacturing firm grinding spring adopts double-end-face vertical grinder.
But this equipment has following shortcoming:
One, because mill spindle designs on the emery wheel door, the hinge of emery wheel door is gapped, often opens and closes the emery wheel door when changing emery wheel, thus cause the parallel accuracy between mill spindle and the grinding wheel spindle to descend, thus the reduction grinding accuracy;
Two, the mill bearing clearance can not be adjusted, the transmission mechanisms such as whole mill transmission adopted decelerator, and manufacturing cost is high.
Three, spring is stuck because of accident, and mill can not stop automatically, easily damages parts.
Four, after the mill bearing wear, its gap can not be regulated, and has a strong impact on mill spring precision.
Therefore, the inventor makes further research this, develops double-ended grinding machine mill structure, and this case produces thus.
Summary of the invention
The object of the present invention is to provide double-ended grinding machine mill structure, can improve grinding accuracy, spring is stuck because of accident, and mill can stop automatically, and simple in structure.
To achieve these goals, technical scheme of the present invention is as follows:
Double-ended grinding machine mill structure comprises base, motor, and transmission mechanism, emery wheel group and mill, motor and mill are connected by transmission mechanism; Described transmission mechanism comprises pulley concial disk A, and pulley concial disk B and V belt have the different pulley groove of three road radiuses on the pulley concial disk A.
As preferably, motor is fixed on the L shaped motor plate.
As preferably, place, motor plate right angle is articulated on the smooth pin by slip cap, and smooth pin is articulated on the base.
As preferably, also be provided with an adjusting bolt on the base, adjusting bolt can swing by the regulating electric machine plate.
As preferably, transmission mechanism also comprises mill spindle and bearing, and bearing is taper roll bearing.
As preferably, round nut is housed also on the mill spindle.
As preferably, mill spindle and emery wheel group all are arranged in the same emery wheel case.
After adopting such scheme, the present invention compared with prior art has the following advantages:
One, because the diameter of pulley groove differs, vary on the different pulley grooves by V belt,
Can realize the adjusting of mill speed speed, adapt to different grinding requirements;
Two, because on the bearing of mill spindle round nut is housed, can adjust mill spindle by adjusting round nut, carry
High mill spindle transmission stiffness and transmission accuracy;
Three, by adjusting bolt, pushing motor plate, the position of fine setting motor, the degree of tightness that can regulate V belt
Adapt to different mill torque demands, when spring was stuck because of accident, mill can stop automatically.
Four, mill spindle and two emery wheel grinding-heads all design in same emery wheel case, have realized keeping for a long time the high parallelism precision of mill spindle and grinding wheel spindle constant.

The specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, shown in Figure 2, the double-ended grinding machine mill structure that the present invention discloses comprises base 1, motor 2, transmission mechanism, emery wheel group 7 and mill 6; Described transmission mechanism comprises pulley concial disk A31, pulley concial disk B32, V belt 33, worm screw 41, worm gear 42, flat key 5, mill spindle 61; Pulley concial disk A31 and motor 2 are connected, and pulley concial disk B32 is connected with pulley concial disk A31 by V belt 33; Worm screw 41 is installed on the pulley concial disk B32, and worm gear 42 is connected with worm screw 41, and an end of flat key 5 is in worm gear 42, and the other end is in mill spindle 61; Mill 6 usefulness bolts 8 are fixed on the mill spindle 61, between emery wheel group 7.
As shown in Figure 2, wherein on the pulley concial disk 33 the different pulley groove of three road radiuses is arranged; Motor 2 is fixed on the L shaped motor plate 21, and place, motor plate 21 right angle is articulated on the smooth pin 23 by slip cap 24, and smooth pin 23 is articulated on the base 1.
If need to change the position of V belt 33 in pulley groove, only motor plate 21 need to be lifted as the center of circle take smooth pin 23 together with motor 2, after V belt 33 becomes flexible, V belt 33 is packed in the required pulley groove.And because motor plate 21 is articulated on the smooth pin 23, can motor 2 and motor plate 21 be adjusted to suitable position by the rotation of motor 2 self.
Further, motor plate 21 the latter halfs are fixed on the base 1 by adjusting bolt 22.
When turning adjusting bolt 22, motor plate 21 is subject to the promotion of adjusting bolt 22, change the position of motor 2, namely changed the distance of pulley concial disk A31 with respect to pulley concial disk B32, degree of tightness that can micro-adjusting triangle belt, adapt to different mill torque demands, and spring is when being stuck because of accident, mill can stop automatically.
Further, mill spindle and emery wheel group all are arranged in the same emery wheel case, so just can keep for a long time mill spindle and the high depth of parallelism of grinding wheel spindle.
Operation principle of the present invention is:
As preferably, transmission mechanism also comprises bearing, and bearing is taper roll bearing 63, and round nut 64 also is housed on the mill spindle 61, can adjust mill spindle 61 by adjusting round nut 64, improves mill spindle 61 transmission stiffnesses and transmission accuracy.
Above-mentioned only is specific embodiments of the invention, but design concept of the present invention is not limited to this, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
