Description
Technical field
The utility model relates to grinding machine equipment, especially a kind of automotive drum type braking sheet outer arc grinding machine.
Background technology
The friction cambered surface of automotive drum type braking sheet need to complete by grinding.Existing automotive drum type braking sheet outer arc grinding machine is mainly comprised of frame, grinding head grinding wheel and transmission mechanism, mold and feed mechanism and electric control system, wherein grinding head grinding wheel passes through belt pulley driven rotary by main motor, lay the mold device of brake block workpiece on the mold main shaft above self-powered platform, brake block workpiece is held and is arranged on mold by reducing motor driven rotary, by grinding head grinding wheel, the extrados of brake block is carried out to grinding, the problem existing is that the installation of mold and brake block workpiece is inconvenient, and work efficiency is low.
Summary of the invention
The purpose of this utility model is by improvements over the prior art, proposes a kind of new drum-type brake pad outer arc grinding machine.The technical solution adopted in the utility model is: drum-type brake pad outer arc grinding machine, comprise frame, grinding head grinding wheel and transmission mechanism, mold and feed mechanism and electric control system, described grinding head grinding wheel passes through belt pulley driven rotary by main motor, described mold device is on the mold main shaft above self-powered platform, by reducing motor driven rotary, described electric control system adopts independently electric operation cabinet, it is characterized in that described mold is by pallet, claw and the arc surface consistent with the intrados of brake block form, pallet is positioned at the below of mold, claw is fixed on the rear side of brake block direction of rotation, brake block is located.
The center connecting hole of described mold is that taper hole ，Gai center taper hole partly matches with the cone of mold main shaft.
The beneficial effects of the utility model and feature are: adopt pallet, claw and the arc surface consistent with the intrados of brake block to form the mold of laying brake block workpiece, add and only brake block workpiece need be served to pallet man-hour, its intrados is close on the arc surface that leans against mold, claw is located it at the rear side of the brake block direction of motion, can carry out attrition process.Brake block, can automatically exit mold after grinding head grinding wheel processing, has alleviated workman's labour intensity, has improved operating efficiency, is applicable to streamline processing.The center connecting hole of mold is made as to taper hole ，Qi center taper hole and partly matches with the cone of mold main shaft, make mold centre bore more reliable with coordinating of mold main shaft, reduced assemblage gap, guaranteed machining accuracy and the quality of product.
According to production needs, on the mold main shaft of grinding machine, can change easily the mold of different size.By the specification requirement of different model, specification brake block, by the arc surface of prefabricated mold, can manufacture the brake block product of sheet type uniform thickness, also can manufacture the not brake block product of uniform thickness of sheet type, meet the processing needs of the drum-type brake pad of different technologies requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to one of embodiment of signal;
Fig. 3 be Fig. 1 A to signal embodiment two.
Number in the figure represents respectively: 1-grinding head grinding wheel, 2-grinding wheel spindle, 3-belt pulley, the main motor of 4-, 5-frame, 6-self-powered platform, 7-adjusts handle up and down, and 8-longitudinally adjusts handle, and 9-laterally adjusts handle, 10-reducing motor, 11-pallet, 12-brake block, 13-mold, the cone part of 14-mold main shaft, 15-block.
The specific embodiment
Shown in Fig. 1, drum-type brake pad outer arc grinding machine comprises frame 5, grinding head grinding wheel 1 and transmission mechanism, mold 13 and feed mechanism and electric control system.Grinding head grinding wheel 1 passes through belt pulley 3 driven rotary by main motor 4; Lay mold 13 devices of brake block workpiece on the mold main shaft above self-powered platform 6, by reducing motor 10 driven rotary; Electric control system adopts independently electric operation cabinet (not shown in FIG.), can adopt the control circuit that integrated circuit or electrical equipment form and the operation push-button that is arranged at operation counter top etc., it requires to design according to the control of each running part of lathe, Machine Tool Electric Appliance is controlled comprehensively, and its control mode is known technology contents.
Fig. 2 is that the A of Fig. 1 is to one of embodiment of signal, in figure, be clearly shown that pallet 11, the claw 15 of mold 13 and the state that is placed in the brake block 12 on mold 13, the extrados of the arc surface of its mold 13 and brake block 12 is the same center of circle, and it is an example for the manufacture of the drum brakes flake products of sheet type uniform thickness.
Fig. 3 be Fig. 1 A to signal embodiment two, the arc surface of its mold 13 is shown for it and the extrados of brake block 12 can adopt not concentric, by the different arc surface of prefabricated mold 13, can manufacture the not drum brakes flake products of uniform thickness of various types, L1>L2 as shown in FIG..
In practical application, brake block 12 after intrados grinding is qualified is close on the arc surface that card leans against mold 13, by claw 15 to its location, mold 13 rotates under the drive of reducing motor 10, simultaneously, grinding head grinding wheel 1 passes through belt pulley 3 driven rotary by main motor 4, now by shaking, adjust up and down handle 7 respectively, longitudinally adjust handle 8 or laterally adjust handle 9, brake block extrados on mold 13 is drawn close to 1 contraposition of diamond grinding head grinding wheel, the extrados of brake block 12 is ground to needed desirable R value.For the brake block 12 of different radii, only need to change the mold 13 of different size, can carry out grinding to the drum-type brake pad extrados of all size.
