Abstract
The utility model provides a motor carbon brush grinder, the features are that a clamp frame is arranged on the tool set, a pair upper and lower plywood are arranged in the slideway of the side board, two slideways are arranged on the bottom plate of the tool set, a tool rack is arranged in the slideways, a feed screw nut is fixed on the front and behind side board of the tool rack, a tool lead screw is connected with two screw nuts through thread, tool clamps used to clamping tools are fixed on the tool lead screw. The utility model can fully guarantee the contacts between the carbon brush and the commutators or the slip ring, so as to enhance the reliability of the motor, and come down the repair rate.
Description
The utility model relates to a kind of mill that grinds carbon brush for electric machine.
Up to now, the cambered surface of carbon brush for electric machine is ground the method that still adopts hand lapping or do not grind direct use, hand lapping exists some significantly deficiencies: 1, grinding precision is low, grind back carbon brush and commutator or slip ring and can not guarantee comprehensive engagement, both loose contact meetings cause the spark between carbon brush and the commutator to strengthen, influence the commutating characteristics of motor, power of motor is reduced, caused power consumption to strengthen; If slip ring and carbon brush loose contact can make the conductive current of carbon brush thereby reduce, cause power of motor to descend.2, hand lapping is wasted time and energy, and efficient is low.3, Grinding Quality is poor, and carbon brush service life is reduced, and can stay hidden danger such as commutator damage.How improving the Grinding Quality of carbon brush as early as possible, then is people's urgent problem.
The purpose of this utility model provides a kind of carbon brush for electric machine mill, and it can realize improving the purpose of Grinding Quality and grinding efficiency.
In order to achieve the above object, the technical solution of the utility model is: it comprises tool seat, this tool seat is provided with fixture mount, on the side plate of fixture mount, be provided with two slideways, have a pair of on, lower plate is contained in the above-mentioned side plate slideway, be connected a clamping screw between train wheel bridge and the fixture mount, on the base plate of tool seat, be provided with two slideways, one toolframe is contained in the above-mentioned slideway versatilely, before the toolframe, be fixed with feed screw nut on the back side panel, one cutter leading screw is connected with two feed screw nuts by screw thread, is fixed with the tool mounting that clamps cutter on the above-mentioned cutter leading screw.
All be fixed with nut on tool seat and the toolframe, a drive screw screw thread is connected with two nuts.
The utility model compared with prior art has the following advantages and good effect: when 1, grinding carbon brush, brush holder is held between the lower plate, hand cutter leading screw drives cutter and rotates, the cutting carbon brush, be cut into required arc surface until carbon brush, the Grinding Quality height, and improved grinding efficiency.2, adopt the utility model to grind carbon brush, can guarantee contacting of carbon brush and commutator or slip ring fully, guarantee that contact-making surface is good, improved the functional reliability of motor, make maintenance rate decline.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a stereogram of the present utility model.
1, fixture mount; 2, handle; 3, tool seat; 4, toolframe; 5, cutter crank; 6, feed screw nut; 7, cutter screw mandrel; 8, screw; 9, cutter; 10, tool mounting; 11, lower plate; 12, train wheel bridge; 13, clamping screw; 14, slideway; 15, slideway; 16, milling tool; 17, nut; 18, drive screw.
Referring to Fig. 1, the utility model is in order to grind the custom-designed specific purpose tool of carbon brush, its structure is: it comprises tool seat 3, this tool seat 3 is provided with fixture mount 1, on the side plate of fixture mount 1, be provided with two slideways 15, have a pair of on, lower plate 12,11 are contained in the above-mentioned side plate slideway 15, be connected a clamping screw 13 between train wheel bridge 12 and the fixture mount 1, on the base plate of tool seat 3, be provided with two slideways 14, one toolframe 4 is contained in the above-mentioned slideway 14 versatilely, before the toolframe 4, be fixed with feed screw nut 6, one cutter leading screws 7 on the back side panel and be connected with two feed screw nuts 6, be fixed with the tool mounting 10 that clamps cutter 9 on the above-mentioned cutter leading screw 7 by screw thread.All being fixed with nut 17, one drive screws 18 screw threads on tool seat 1 and the toolframe 4 is connected with two nuts 17.
When need grind carbon brush, can carbon brush be clamped in the upper and lower clamping plate 12,11 by clamping screw 13, rotating drive screw rod 18 makes it drive toolframe 4 and moves forward to the desired position along slideway 14, rotary cutter crank 5 makes it drive cutter screw mandrel 7 and rotates, thereby make cutter 9 cutting carbon brush, whenever turn around, cutter 9 moves forward the distance of a pitch, until the carbon brush cutting is finished.Adopt the utility model to grind carbon brush for electric machine, grinding precision height, efficient height.
