Description
Technical field
The utility model relates to crankcase manufacture field, relates to a kind of crankcase endoporus sanding apparatus.
Background technology
Crankcase is generally aluminum alloy die casting, one-body molded, and its shape is comparatively complicated, various hole and face more, and position and size dimension require strict.There is many burrs at edge and endoporus place in the crankcase after shaping, the existence of burr to machining accuracy, the assembly precision of part, all can produce harmful effect in processing nail tail and presentation quality etc. are many.Burr on the parts of relative motion in assembling process can cause surface abrasion or come off and develop into fifth wheel at box house.Owing to there is burr, part may not reach cooperation position, if reach cooperation position, more coarse, then compressive load per unit area is larger, and surface is more easy to wear.Therefore, need to polish to each axis hole after machining, to remove the burr in endoporus, ensure crudy, improve the quality of fit between part.
The polishing majority of the endoporus of existing crankcase adopts artificial hand-held milling tools to polish one by one to the hole on casing, its workload is large, labour intensity is large, higher to the requirement of operator, very easily tired impact polishing quality after long-time operation, the hole number of time processing is limited, and grinding efficiency is low.
Utility model content
The utility model is intended to provide a kind of crankcase endoporus sanding apparatus, to reduce crankcase endoporus polishing intensity, improves endoporus grinding efficiency.
For achieving the above object, basic technology scheme of the present utility model is as follows: crankcase endoporus sanding apparatus, comprise frame, gripper shoe, motor, described frame comprises the workbench of rectangle and is fixed on the support column in four corners, workbench lower end, described gripper shoe is fixed on the below of workbench by support column, and described motor is fixing on the supporting plate.The lower end of described workbench is fixed with gear-box, and the output shaft of described motor is connected with gear-box, and the upper end of described workbench is provided with multiple limited post and installing hole.Endoporus one_to_one corresponding on described installing hole and crankcase coaxial line, be provided with polishing rod in described installing hole, the bottom of described polishing rod is connected with the rotating shaft of inner gear of the gear box.
Principle and the advantage of this programme are: during operation, starter motor, the pinion rotation in the output shaft driven gear case of motor, and gear driven polishing rod rotates.After needing the crankcase endoporus alignment polishing rod of processing, crankcase is placed on the table, carry out spacing by limited post to casing.Polishing rod rotates and carries out polishing deburring operation to crankcase endoporus.This programme adopts motor to drive polishing rod to polish to crankcase endoporus, carry out spacing by limited post to casing, do not need artificial hand-held milling tools, instead of manually with electronic, significantly reduce labour intensity, the impact of human factor on crudy is less.And multiple polishing rod once can be polished to multiple hole simultaneously, improve the efficiency of polishing deburring, reduce time cost.
Preferred version one, based on the one of scheme improve, described polishing rod comprises columniform barred body and is detachably connected on polishing layer outside barred body.Such setting does not need barred body according to the different polishing layers needing to change different roughness, can realize the operations such as the corase grind to endoporus, fine grinding from workbench dismounting.
Preferred version two, preferably the one of is improved, and described polishing layer is sand paper.Sand paper is conventional milling tools, and its polishing is effective, and take conveniently, with low cost, granularity selection is applicable to the polishing of different roughness more, makes the polishing of crankcase endoporus more convenient, polishing better effects if.
Preferred version three, preferably two one improve, described gripper shoe lower surface and support column between be provided with reinforcement.Arrange reinforcement like this to reinforce the annexation between gripper shoe and support column, the weight capacity of gripper shoe is improved, make device more stable, firm.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: workbench 1, support column 2, gripper shoe 3, motor 4, gear-box 5, limited post 6, polishing rod 7, reinforcement 8.
Embodiment is substantially as shown in Figure 1: crankcase endoporus sanding apparatus, comprise frame, gripper shoe 3, motor 4, described frame comprises the workbench 1 of rectangle and is fixed on the support column 2 in four corners, workbench 1 lower end, described gripper shoe 3 is fixed on the below of workbench 1 by support column 2, described motor 4 is fixed in gripper shoe 3.The lower end of described workbench 1 is fixed with gear-box 5, and the output shaft of described motor 4 is connected with gear-box 5, and the upper end of described workbench 1 is provided with multiple limited post 6 and installing hole.Endoporus one_to_one corresponding on described installing hole and crankcase coaxial line, be provided with polishing rod 7 in described installing hole.Described polishing rod 7 comprises columniform barred body and is detachably connected on the polishing layer outside barred body, and the bottom of described barred body is connected with the rotating shaft of gear-box 5 internal gear.
In the present embodiment, during operation, starter motor 4, the pinion rotation in the output shaft driven gear case 5 of motor 4, gear driven polishing rod 7 rotates.After needing the crankcase endoporus of processing alignment polishing rod 7, crankcase is placed on workbench 1, is undertaken spacing by limited post 6 pairs of casings.Polishing rod 7 rotates and carries out polishing deburring operation to crankcase endoporus.Polishing layer is detachably connected on barred body by this programme does not need barred body to dismantle according to the different polishing layers needing to change different roughness, can realize the operations such as the corase grind to endoporus, fine grinding from workbench 1.Adopt motor 4 to drive polishing rod 7 pairs of crankcase endoporus to polish, undertaken spacing by limited post 6 pairs of casings, do not need artificial hand-held milling tools, instead of manually with electronic, significantly reduce labour intensity, the impact of human factor on crudy is less.And multiple polishing rod 7 once can be polished to multiple hole, improves the efficiency of polishing deburring, reduces time cost simultaneously.
Layer of polishing described in the present embodiment is sand paper.Sand paper is conventional milling tools, and its polishing is effective, and take conveniently, with low cost, granularity selection is applicable to the polishing of different roughness more, makes the polishing of crankcase endoporus more convenient, polishing better effects if.Described gripper shoe 3 lower surface and support column 2 between be provided with reinforcement 8.The annexation arranged like this between reinforcement 8 pairs of gripper shoes 3 and support column 2 is reinforced, and the weight capacity of gripper shoe 3 is improved, and makes device more stable, firm.
