Description
Technical Field
The invention relates to the technical field of engine part polishing tools, in particular to a self-adaptive grinding tool for a vertical crankshaft.
Background
At present, bent axle among the prior art cleaning equipment that polishes mainly has following several big problems: 1. present bent axle polisher is mostly for the manual work piece and the work piece transportation from top to bottom, degree of automation is lower, a large amount of manpower resources have been occupied, 2, present bent axle polisher is when transporting the work piece, owing to receive grinding device's unit efficiency restriction, generally can only once accomplish the bent axle of one or two and transport, work efficiency is low, if choose for use many equipment, then take up an area of too big, the production requirement of production can not be satisfied, 3, each part overall arrangement is unreasonable in the current bent axle polisher equipment, it is poor to cause equipment overall structure compactness, area is great, power consumption is many.
To solve the problems, the intellectual property office of China discloses an invention patent with application number 201810165312.6, which comprises a fixed plate, wherein the top of the fixed plate is fixedly connected with an operation table, two sides of the bottom of the fixed plate are fixedly connected with supporting legs, the top of the fixed plate is fixedly connected with a connecting plate on the left side of the operation table, the bottom of the fixed plate is provided with a motor between the two supporting legs, an output shaft of the motor is fixedly connected with a gear, the top of the gear is provided with a toothed plate meshed with the gear, and the right end of the toothed plate penetrates through the supporting legs and extends to the outside of the supporting legs. According to the invention, the gear can be driven to rotate through the arrangement of the motor, the moving rod and the connecting rod are driven to move through the matching of the gear and the toothed plate, the workpiece can be positioned and processed through the clamping plate driven by the fixing rod through the arrangement of the connecting rod and the adjusting plate, and meanwhile, the problem that the workpiece is rocked and the polishing quality is influenced because the workpiece cannot be positioned when the workpiece is polished and processed is solved.
But the device is gradually exposed to the technical shortcomings along with the use of production:
first, the device utilizes two (holding) chucks to fix the bent axle, but as is well known, utilize this mechanism can realize being convenient for the location when small-size bent axle, when meetting large-scale bent axle, utilize this fixed mode then can't guarantee the axiality of bent axle and rotate for it rotates the in-process and easily appears rocking, influences the precision of polishing.
Secondly, when the device utilizes the (holding) chuck to fix the bent axle again, known in the week, the radial force that the bent axle bore in the actual work in-process, it can't bear big axial force, when utilizing the (holding) chuck when fixing the bent axle, because of guaranteeing the relative clamping-force of (holding) chuck, needs the both ends of a big clamping-force effect in the bent axle, this makes the bent axle bear in big axial force, and the bent axle that easily makes produces stress concentration, influences the installation and use in the later stage of bent axle, reduces the life of bent axle.
Thirdly, when the device polishes the crankshaft by using the polishing head, the large polishing surface of the crankshaft is irregular, so that the polishing head is limited by the irregular shape of the crankshaft when in frictional contact with the crankshaft, and the phenomena of overlarge polishing amount of partial surface of the crankshaft and insufficient polishing amount of partial surface often occur; wherein if the volume of polishing is not enough only need adjust the position of polishing head and bent axle and carry out the secondary and polish can, only cost some time and labour, but if the volume of polishing is too big then directly lead to the unable use of whole bent axle, lead to the emergence of extravagant phenomenon, improved manufacturing cost.
Fourthly, the width of the grinding wheel is smaller than that of the grinding position of the crankshaft, so that the grinding wheel needs to be moved back and forth to grind the surface of the local crankshaft, and when the widths of a plurality of parts of the crankshaft are different, the displacement of the grinding wheel needs to be adjusted repeatedly, labor force output is increased, time consumption is high, and grinding efficiency is reduced.
Fifthly, the grinding wheel is limited by the structure of the grinding wheel, so that the grinding wheel can only grind along the radial direction of the crankshaft, when the side part of the crankshaft is required to be ground, the auxiliary tool is required to be manually utilized for grinding, the labor force output is increased, and the grinding efficiency is low.
The problems are encountered in the grinding process of the crankshaft, wherein research and development personnel grind the crankshaft on the premise of fixing the crankshaft by ensuring fastening, and the stress influence on the crankshaft is neglected; in order to realize that the same grinding amount of the crankshaft surface cannot be ensured when the crankshaft surface is ground; when parts of the crankshaft with different widths are polished, the displacement needs to be frequently adjusted; and the phenomenon that the side wall of the crankshaft is subjected to auxiliary grinding by an auxiliary tool by virtue of the grinding wheel.
From the above, it is obvious that the prior art has inconvenience and disadvantages in practical use, so that improvement is needed.
