Abstract

The utility model discloses a static balance structure of a flat grinder. An annular counter weight 2 coaxial with a driving motor is arranged on the driving motor 1 of a grinder spindle, the weight of the counter weight 2 is 4 to 6kg, and the distance between the counter weight 2 and a driving motor rear end 10 is 20 to 30mm. According to the static balance structure, the counter weight is additionally arranged on the driving motor, so that torque of the upper half part, which has a forward turning trend, of the grinder is generated by devices such as a grinding wheel and a grinding wheel shield, which are fixed at the front end of the spindle, and is balanced by the counter weight block, so that the actual position and the theoretical position of the grinding wheel are identical, and the grinding accuracy of the grinder is guaranteed.

Description

The static balance structure of surface grinding machine

Technical field

The utility model relates to a kind of static balancing apparatus, is specifically related to a kind of static balance structure of surface grinding machine.

Background technology

The front-end of spindle of surface grinding machine is consolidated with equipment such as emery wheel, wheel-guard and illuminator; Make the first half of surface grinding machine have the light problem in preceding heavy back; The trend of turning over before so the first half of grinding machine has, thus make emery wheel approach workpiece more than theoretical position, and promptly the physical location of emery wheel and theoretical position deviation are bigger; Cause grinding accuracy low, have a strong impact on workpiece quality.

For addressing the above problem, a kind of static balance structure that makes surface grinding machine be in the static balance state need be provided.

Summary of the invention

The utility model purpose provides a kind of static balance structure of surface grinding machine, and through the use of this static balance structure, main spindle box is fixed, can run-off the straight, and the grinding machine precision is high.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of static balance structure of surface grinding machine; The drive motors of said grinding machine spindle is provided with balancing weight, and the weight of said balancing weight is 4～6kg, and said balancing weight is 20～30mm apart from the distance of drive motors rear end.

In the technique scheme, said balancing weight is a loop configuration, and balancing weight is coaxial with drive motors.

In the said structure, before having, the first half that makes grinding machine that the equipment such as emery wheel, wheel-guard that utilize balancing weight to be fixed on front-end of spindle with balance produce turns over torque, the physical location of emery wheel and the theoretical position zero deflection of trend.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1, the utility model is set up balancing weight on the drive motors of main shaft; Before having, the first half that makes grinding machine that the equipment such as emery wheel, wheel-guard that utilize balancing weight to come balance to be fixed on front-end of spindle produce turns over the torque of trend; The physical location of emery wheel and theoretical position zero deflection, the grinding accuracy of assurance grinding machine.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment one;

Wherein: 1, main spindle box; 10, main spindle box rear end; 2, balancing weight.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment one: referring to shown in Figure 1; A kind of static balance structure of surface grinding machine; The drive motors 1 of said grinding machine spindle is provided with the annular balancing weight 2 coaxial with drive motors, and the weight of said balancing weight 2 is 4～6kg, and said balancing weight 2 is 20～30mm apart from the distance of drive motors rear end 10.

Before having, the first half that makes grinding machine that the equipment such as emery wheel, wheel-guard that present embodiment utilizes balancing weight to come balance to be fixed on front-end of spindle produce turns over torque, the physical location of emery wheel and the theoretical position zero deflection of trend.
