Abstract
A valve spring compressor is used for mounting and dismounting a valve spring, and comprises screws used for connecting a cylinder cover; a screw rod is mounted in the center of a fixing plate; a spring compression plate is sleeved on the screw rod; and a nut is screwed on the screw rod. The valve spring is dismounted through the method: fixing the fixing plate on the cylinder cover by the screws, sleeving the spring compression plate on the screw rod to enable a notch of the spring compression plate to be sleeved on a push rod, compressing the spring by the spring compression plate, adjusting the nut, compressing the spring through a threaded interlocking force, dismounting a clamp ring by a screwdriver or needle-nose pliers, and taking down the compressor; and the valve spring is mounted through the same method: compressing the spring, mounting the clamp ring, and loosing the compressor. In mounting and dismounting the valve spring, the utility model can effectively protect engine accessories and reduces the maintenance workload and lowers the maintenance cost.
Description
Technical field
The utility model relates to machinery manufacturing technology field, is a kind of instrument that is used for the dismounting valve spring specifically.
Background technology
At present, when the dismounting engine valve spring, all be to adopt nipper plier directly to press from both sides the air outlet valve spring collar.This kind method can cause the damage of push rod, also can produce influence to a certain degree to valve spring simultaneously, increases maintenance capacity.
Summary of the invention
The deficiency that causes engine accessory power rating to damage in order to overcome existing method dismounting valve spring, the goal of the invention of the utility model is to provide a kind of valve spring compressor, takes on collar, the purpose of dismounting spring to realize easily getting.
For realizing above-mentioned purpose, the utility model comprises the screw that is used to connect cylinder cap, and screw rod is equipped with at the center of fixed head, and the spring compressive plate is enclosed within on the screw rod, and nut is spun on the screw rod.
During dismounting, fixed head is fixed on the cylinder cap, the spring compressive plate is inserted in screw rod with screw; The indentation, there of spring compressive plate is enclosed within on the push rod, and compressive plate then compresses spring, adjusting nut; Utilize screw thread interlocking power that spring is compressed; Utilize bottle opener or nipper plier to pull down collar, take off compressor reducer, promptly detachable spring; When valve spring is installed, adopt the dead spring that uses the same method, load onto collar, unclamp compressor reducer and get final product.
The utility model compared with prior art can effectively be protected engine accessory power rating when light dismounting valve spring, reduce maintenance and maintenance cost.
Description of drawings
Accompanying drawing is the stereogram of the utility model.
The specific embodiment
Shown in accompanying drawing, screw rod 5 is equipped with at the center of fixed head 1, and spring compressive plate 2 is enclosed within on the screw rod 5, and nut 4 is spun on the screw rod 5, and pad 6 is housed on the spring compressive plate 2.
During dismounting, utilize two screws 3 fixed head 1 to be fixed on the cylinder cap mounting spring compressive plate 2; Make its just pressing spring and reserve the position of push rod, load onto pad 6, nut 4, with spanner rotation nut 4; Utilize screw thread interlocking power that spring is depressed; Pull down collar with bottle opener or nipper plier again, take off compressor reducer, promptly detachable spring; When valve spring is installed, adopt the dead spring that uses the same method, load onto collar, unclamp compressor reducer and get final product.
