Embodiment 1

[0035] Such as Figure 1 to Figure 6 As shown, the present invention has the grinding wheel device of the output shaft anti-rotation assembly, including the motor 1, the grinding wheel 3 coaxially installed on the transmission shaft 2 of the motor 1, and the side cover of the grinding wheel 3 fixed on the motor 1 shell The protective cover 4 is set, and the protective cover 4 is fixed on the shell of the motor 1 through a connecting mechanism, and the connecting mechanism includes a connecting assembly, a friction assembly and an unlocking assembly, wherein,

[0036] The connection assembly includes a flange ring 5 sleeved on the casing of the motor 1, a support sleeve 6 sleeved on the drive shaft 2 and connected to the protective cover 4 at one end and abutted against the flange ring 5 at the other end, and a plurality of supporting sleeves. The sleeve 6 and the flange ring 5 are connected and fixed and the fastener 7;

[0037] The friction assembly is located inside the sup...

Embodiment 2

[0049] This embodiment is an implementation description of the linear drive mechanism in Embodiment 1.

[0050] Such as figure 2 As shown, the linear drive mechanism includes an internally threaded cylinder 10 radially inserted on the support sleeve 6 and a screw 11, a bearing 12 and a moving rod 13 connected coaxially in sequence, as shown in Image 6 As shown, the screw 11 is located on the side of the internally threaded cylinder 10 away from the transmission shaft 2, one end of which is inserted into the internally threaded cylinder 10 and screwed with the internally threaded cylinder 10, and the moving rod 13 is located on the internally threaded cylinder 10 close to the transmission shaft 2, one end of which is connected to the insert block 14, and the other end is inserted into the inner hole of the internally threaded barrel 10, and is connected with the screw rod 11 through the bearing 12, and the inner and outer rings of the bearing 12 are respectively connected wit...

Embodiment 3

[0057] This embodiment is a further description of the sliding fit between the friction member and the bottom plate 8 .

[0058] Such as figure 1 with figure 2 As shown, a chute B17 is provided on the bottom plate 8, the axis of the chute B17 is perpendicular to the axis of the transmission shaft 2, and the side of the friction member close to the bottom plate 8 protrudes outward to form a slider 18, so The slider 18 is inserted into the sliding groove B17 and is slidably fitted therewith.

[0059] Further, the end of the chute B17 away from the transmission shaft 2 is a closed end, the spring 9 is located in the chute B17, and is located on the side of the slider 18 away from the transmission shaft 2, and its two ends are connected to the slider 18 respectively. And one end away from the transmission shaft 2 on the chute B17 is connected.

[0060] Correspondingly, when the spring is located on the side of the slider close to the transmission shaft 2 , the tension deformat...

Abstract

The invention discloses a grinding wheel device with an output shaft anti-rotation assembly. The grinding wheel device comprises a motor, a grinding wheel and a protective cover, the protective coveris fixed to a shell of the motor through a connecting mechanism, and the connecting mechanism comprises a connecting assembly, a friction assembly and an unlocking assembly; the connecting assembly comprises a flange ring, a supporting sleeve and a plurality of fasteners for connecting and fixing the supporting sleeve and the flange ring; the friction assembly is located on the inner side of the supporting sleeve and comprises a bottom plate and a friction unit, and the friction unit comprises a friction piece slidably installed on the bottom plate and a spring with the two ends connected withthe friction piece and the bottom plate correspondingly; and the unlocking assembly comprises a linear driving mechanism inserted in the supporting sleeve in the radial direction and an inserting block installed at the driving end of the linear driving mechanism. When a grinding machine is overhauled and tested, the condition that the grinding machine can be tested only when the protective coveris installed is set, so that it is guaranteed that related workers must operate according to regulations, and the safety problem caused by nonstandard operation during grinding machine testing is effectively solved.

Description

technical field [0001] The invention relates to the field of grinders, in particular to a grinder device with an output shaft anti-rotation assembly. Background technique [0002] Grinders are commonly used equipment for sharpening various knives and tools. It is mainly composed of a base, a grinding wheel, a motor as a power source or other power sources, a bracket, a protective cover and a water feeder. The motor is installed on the base, and the grinding wheel is arranged at the end of the transmission shaft of the motor. A protective cover is sheathed on one side of the grinding wheel, and the protective cover is installed on the shell of the base of the grinder. [0003] When the grinding wheel is working, it grinds the parts, and the grinding debris generated during grinding makes a parabolic motion under the rotational torque from the grinding wheel, and is attached to the inside of the protective cover to prevent it from splashing on the workers, especially the eye...
