Abstract
The utility model discloses an engine camshaft shroud processing special fixture, engine camshaft shroud has still increased by 4 auxiliary stays except some fixed stay nail location engine camshaft shroud plane for reduce the vibration among the cutter cutting process, influence processingquality. The utility model discloses a multiple spot auxiliary stay, the vibration of having avoided the cutter cutting to produce prevents the deformation because of pressing from both sides factors such as tight and processing and producing of engine camshaft shroud, can accelerate cutter feed rate, improvement production efficiency. The simulation paintings are suitable for mass production.
Description
Technical field
This utility model relates to a kind of fixture, relates in particular to a kind of Special Fixture for Machining.
Background technology
Engine cam belongs to the critical component of engine valve actuating mechanism, and the overall performance of electromotor is had a significant impact. Engine cam is positioned at the top of electromotor, is made up of admission cam shaft and exhaust cam shaft, controls the unlatching of inlet valve and exhaust valve. Camshaft is arranged in camshaft cover cap in double row cam axis hole, double row cam axis hole in camshaft cover cap is semicircular, must carrying out fit processing together with other assembling parts, therefore the aperture of camshaft hole and the flatness required precision of coaxial precision and camshaft cover cap are very high. Must assure that flatness dimensional accuracy during machining cam axle cover cap, this brings great difficulty to processing, is that the setting of the design of fixture or the selection of cutter and machined parameters is all critically important.
Summary of the invention
In order to solve the problem that camshaft cover cap processing flatness not easily ensures crudy, this utility model provides a kind of special fixture of processing on numerical control machining center, this special fixture ensure that the stability of crudy, improves production efficiency, meets batch production demand.
The technical solution of the utility model is: engine cam cover cap Special Fixture for Machining, is made up of upper flat plate, lower flat board, riser, auxiliary supporting seat, pillar, alignment pin, support nail A, support nail B, cover plate, rotary cylinder 0, screw A, straight pin, screw B, hand-operated direction valve. Wherein upper flat plate, lower flat board, riser screw A, straight pin are fixed and are connected, auxiliary supporting seat, alignment pin, support nail A, support nail B, cover plate, rotary cylinder 0 are fixedly connected on upper flat plate, pillar is connected between upper flat plate, lower flat board, strengthen supporting upper flat plate, lower flat board, engine cam cover cap is except putting fixing support nail location engine camshaft cover cap plane, also add 4 place's auxiliary to support, for reducing the vibration in tool cutting process, affect crudy.
This utility model adopts multiple spot auxiliary to support, it is to avoid the vibration that Tool in Cutting produces, it is prevented that the deformation that engine cam cover cap produces because of factors such as clamping and processing, can accelerate tool feeding speed, improve production efficiency. It is suitable for batch production.

Detailed description of the invention
Engine cam cover cap Special Fixture for Machining, is made up of upper flat plate 1, lower flat board 2, riser 3, auxiliary supporting seat 4, pillar 5, alignment pin 6, support nail A7, support nail B8, cover plate 9, rotary cylinder 10, screw A11, straight pin 12, screw B13, hand-operated direction valve 14. Wherein upper flat plate 1, lower flat board 2, riser 3 screw A11, straight pin 12 are fixed and are connected, auxiliary supporting seat 4, alignment pin 6, support nail A7, support nail B8, cover plate 9, rotary cylinder 10 are fixedly connected on upper flat plate 1, pillar 5 is connected between upper flat plate 1, lower flat board 2, strengthen supporting upper flat plate 1, lower flat board 2, engine cam cover cap is except 3 fixing support nail location engine camshaft cover cap planes, also add 4 place's auxiliary to support, for reducing the vibration in tool cutting process, affect crudy.
2 alignment pins 6 and 3 fixing support nails are arranged in upper flat plate plane, positioning datum as engine cam cover cap, 3 rotary cylinders 10 are adopted to clamp engine cam cover cap, the clamping point of rotary cylinder 10 and the strong point of support nail overlap, it is ensured that the clamping of engine cam cover cap is indeformable. When operation, operator aligns 2 alignment pins 6 engine cam cover cap, it is correctly placed in the location plane of support nail A7 and support nail B8, opening hand-operated direction valve, clamp engine cam cover cap, auxiliary support bar ejects, increase and support engine cam cover cap, after confirming that clamping is errorless, press loop start button, start processing.
