Abstract
The utility model discloses a crankshaft polishing device which comprises a left polishing arm, a right polishing arm and a fixing block. The left polishing arm and the right polishing arm are fixedly mounted on the fixing block, and long grooves are respectively arranged on the top of the left polishing arm and the top of the right polishing arm; a cylinder is mounted on the fixing block and is respectively connected with a tensioning head and a control switch; and the tail end of the left polishing arm and the tail end of the right polishing arm are connected with the fixing block by tension springs. The crankshaft polishing device has the advantages that the crankshaft polishing device is simple in structure and convenient to manufacture, the polishing arms provided with the long grooves are pushed by the cylinder to polish two sides of a crankshaft, the pressure is stable, contact surfaces are uniform, the labor intensity is greatly reduced while the quality of a product is guaranteed, and accordingly the work efficiency is greatly improved; and the device further can be connected with a common lathe by the cylinder, so that the utilization rate of the lathe is greatly increased.
Description
Technical field
The utility model relates to a kind of bent axle burnishing device.
Background technology
Along with improving constantly of crankshaft part processing technology, to the geometrical precision of crankshaft workpiece, surface roughness, working (machining) efficiency require also to improve constantly, to the proposition of shaft neck thrust face two sides processing request, so that the common abrasive band polishing in existing workshop can't have been satisfied existing roughness requirement.Existing thrust surface polissoir usually is that artificial hand is taken wooden stick or rootlet iron staff to withstand the abrasive band to carry out the both sides polishing, burnishing surface is inhomogeneous, meeting jettisoning portion size when top power is large, and a power hour roughness in top does not reach requirement, the manually-operated subjective factor is many, and labor strength is larger.Less for the special-purpose thrust surface polissoir of the bent axle in market, the equipment price of equipment component producer is higher, and cost performance is not high for single track thrust surface polishing process, and equipment is longer process time.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of bent axle burnishing device, it is simple in structure, and is easily manufactured, and the polishing arm that is offered elongate slot by the cylinder promotion polishes the bent axle both sides, pressure stability, contact-making surface is even, greatly reduces labour intensity when guaranteeing product quality, thereby effectively raises operating efficiency, this device can also link to each other with engine lathe by cylinder, has greatly improved the utilization rate of lathe.
The utility model is the purpose that reaches above-mentioned, and the utility model adopts following technical scheme:
A kind of bent axle burnishing device comprises left polishing arm, right polishing arm, fixed block, wherein is installed with left polishing arm and right polishing arm on the fixed block, and left polishing arm and right polishing arm top offer respectively elongate slot; On the described fixed block cylinder is installed, cylinder links to each other with tensioning head, gauge tap respectively; Described left polishing arm links to each other with fixed block by tension spring with right polishing arm end.
On the described tensioning head back-up ring is installed.
Described cylinder links to each other with U-shaped fixed block, and U-shaped fixed block is connected by holding screw and fixed block.
Described tension spring is connected with left polishing arm and right polishing arm end respectively by screw.
Described cylinder links to each other with gauge tap by tracheae.
The beneficial effects of the utility model are: the utility model provides a kind of bent axle burnishing device, it is simple in structure, easily manufactured, the polishing arm that is offered elongate slot by the cylinder promotion polishes the bent axle both sides, pressure stability, and contact-making surface is even, when guaranteeing product quality, greatly reduce labour intensity, thereby effectively raise operating efficiency, this device can also link to each other with engine lathe by cylinder, has greatly improved the utilization rate of lathe.
Description of drawings
Fig. 1 is front view of the present utility model.
The specific embodiment
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of bent axle burnishing device, comprise left polishing arm 2, right polishing arm 1, fixed block 11, wherein be installed with left polishing arm 2 and right polishing arm 1 by set bolt 3 on the fixed block 11, and left polishing arm 2 and right polishing arm 1 top offer respectively elongate slot 12; On the described fixed block 11 cylinder 8 is installed, cylinder 8 links to each other with U-shaped fixed block 6, and U-shaped fixed block 6 is connected by holding screw 7 and fixed block 11, and cylinder 8 links to each other with tensioning 4, gauge tap 13 respectively; Described left polishing arm 2 and right polishing arm 1 end are connected by tension spring 9 and fixed block 11, and tension spring 9 is connected with left polishing arm 2 and right polishing arm 1 end respectively by screw 10.In the described tensioning 4 back-up ring 5 is installed.
When a kind of bent axle burnishing device that uses the present embodiment to provide, at first that fixed block 11 is fixing at the cutter tower of engine lathe, cylinder 8 links to each other with compressed air gauge tap 13 independently by tracheae 14.After compressed air gauge tap 13 was opened, the atmospheric pressure in the cylinder 8 just can increase.After pressure in the cylinder 8 increased, cylinder 8 just can promote tensioning 4 and move up.When tensioning 4 moved up, left polishing arm 2 and right polishing arm 1 increased the angle of upper end.When left polishing arm 2, when right polishing arm 1 lateral surface is parallel with the crankshaft thrust shelves, cylinder 8 stop motions keep present situation, and left polishing arm 2, right polishing arm 1 pass the abrasive band of turning up the crankshaft thrust shelves are carried out the both sides polishing by elongate slot 12.After compressed air gauge tap 13 cut out, the atmospheric pressure in the cylinder 8 just can reduce.The tension spring 9 that is installed on left polishing arm 2 and the right polishing arm 1 makes the bent axle burnishing device return to original state by pulling force, thereby finishes the bent axle polishing.When needing the dismounting bent axle, only need to utilize the auto-feed process of lathe X-direction just can bent axle for convenience detach.
A kind of bent axle burnishing device of the present embodiment manufacturing, it is simple in structure, easily manufactured, the polishing arm that is offered elongate slot by the cylinder promotion polishes the bent axle both sides, pressure stability, and contact-making surface is even, when guaranteeing product quality, greatly reduce labour intensity, thereby effectively raise operating efficiency, this device can also link to each other with engine lathe by cylinder, has greatly improved the utilization rate of lathe.
