Abstract
The invention discloses a crankshaft polishing device which comprises a left polishing arm, a right polishing arm and a fixed block, wherein the left polishing arm and the right polishing arm are fixedly installed on the fixed block, and long grooves are respectively arranged at the top ends of the left polishing arm and the right polishing arm; a cylinder is installed on the fixed block and respectively connected with a tension head and a control switch; and the tail ends of the left polishing arm and the right polishing arm are connected with the fixed block through tension springs. The crankshaft polishing device is simple in structure and convenient to manufacture, the cylinder pushes the polishing arms provided with the long grooves to perform polishing on two sides of a crankshaft, and the crankshaft polishing device is stable in pressure, even in contact surface, ensures product quality, simultaneously greatly reduces labor intensity, accordingly effectively improves working efficiency, further can be connected with an ordinary lathe through the cylinder, and greatly improves utilization rate of the lathe.
Description
Technical field
The present invention 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 requires also to improve constantly, to the proposition of two sides, shaft neck thrust face processing request, make the common abrasive band polishing in existing workshop cannot meet existing roughness requirements.Existing thrust surface polissoir is usually that artificial hand is taken wooden stick or rootlet iron staff to withstand abrasive band to carry out both sides polishing, burnishing surface is uneven, meeting jettisoning portion size when top power is large, and a power hour roughness in top does not reach requirement, manual operation subjective factor is many, and labor strength is larger.Bent axle for market special thrust surface polissoir is less, and the equipment price of equipment component producer is higher, and for single track thrust surface polishing process, cost performance is not high, and equipment is longer for process time.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of bent axle burnishing device, its structure is simple, easily manufactured, and the polishing arm being promoted to offer elongate slot by cylinder carries out polishing to bent axle both sides, pressure stability, contact surface is even, greatly reduces labour intensity, thus effectively raise operating efficiency while guarantee product quality, this device can also be connected with engine lathe by cylinder, substantially increases the utilization rate of lathe.
The present invention reaches above-mentioned object, and the present invention adopts following technical scheme:
A kind of bent axle burnishing device, comprise left polishing arm, right polishing arm, fixed block, wherein one end of fixed block is fixedly installed on the cutter tower of machine tool, fixed block is installed with left polishing arm and right polishing arm, and left polishing arm and right polishing arm top offers elongate slot respectively simultaneously; Fixed block is installed with left polishing arm and right polishing arm by set bolt; Described fixed block is also provided with cylinder, and cylinder is connected with tensioning head, gauge tap respectively; Described left polishing arm is connected with fixed block by tension spring with right polishing arm end.
Described tensioning head is provided with back-up ring.
Described cylinder is connected with U-shaped fixed block, and U-shaped fixed block is connected by holding screw and fixed block.
Described cylinder is connected with gauge tap by tracheae.
Beneficial effect of the present invention is: the invention provides a kind of bent axle burnishing device, its structure is simple, easily manufactured, the polishing arm being promoted to offer elongate slot by cylinder carries out polishing to bent axle both sides, pressure stability, and contact surface is even, labour intensity is greatly reduced while guarantee product quality, thus effectively raising operating efficiency, this device can also be connected with engine lathe by cylinder, substantially increases the utilization rate of lathe.

Fig. 1 is front view of the present invention.
Detailed description of the invention
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 fixed block 11 is installed with left polishing arm 2 and right polishing arm 1 by set bolt 3, and left polishing arm 2 and right polishing arm 1 top offer elongate slot 12 respectively; Described fixed block 11 is provided with cylinder 8, and cylinder 8 is connected 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 is connected 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.Described tensioning 4 is provided with back-up ring 5.
When a kind of bent axle burnishing device using the present embodiment to provide, first that fixed block 11 is fixing on the cutter tower of engine lathe, cylinder 8 is connected with independently compressed air gauge tap 13 by tracheae 14.After compressed air gauge tap 13 is opened, the atmospheric pressure in cylinder 8 just can increase.After pressure in cylinder 8 increases, cylinder 8 just can promote tensioning 4 and move up.When tensioning 4 moves up, left polishing arm 2 and right polishing arm 1 increase the angle of upper end.When left polishing arm 2, right polishing arm 1 lateral surface are parallel with crankshaft thrust shelves, cylinder 8 stop motion keeps present situation, and left polishing arm 2, right polishing arm 1 carry out both sides polishing through the abrasive band of turning up to crankshaft thrust shelves by elongate slot 12.After compressed air gauge tap 13 cuts out, the atmospheric pressure in cylinder 8 just can reduce.The tension spring 9 be arranged on left polishing arm 2 and right polishing arm 1 makes bent axle burnishing device return to original state by pulling force, thus completes bent axle polishing.When needing dismounting bent axle, only need to utilize lathe X to auto-feed process just can bent axle for convenience detach.
A kind of bent axle burnishing device manufactured by the present embodiment, its structure is simple, easily manufactured, the polishing arm being promoted to offer elongate slot by cylinder carries out polishing to bent axle both sides, pressure stability, and contact surface is even, labour intensity is greatly reduced while guarantee product quality, thus effectively raising operating efficiency, this device can also be connected with engine lathe by cylinder, substantially increases the utilization rate of lathe.
