Abstract
The utility model relates to an endurance testing device for a return spring of an electric tool, in particular to a cylinder-type spring endurance testing device, which mainly comprises a bottom plate, a vertical column, a cylinder assembly, a cylinder position adjustment component and a control box. The cylinder assembly comprises a simulation press arm, a fixing steel plate, a proximity switch, a cylinder and a cylinder stroke limit nut, and the cylinder position adjustment component a vertical cylinder movement adjusting plate, a cylinder angle and back-and-forth cylinder movement adjusting plate and a left-right cylinder movement adjusting plate. The vertical column is vertically connected with the bottom plate, the vertical cylinder movement adjusting plate is sleeved in the vertical column, and the cylinder is connected with the cylinder position adjustment component. Since the installation position and acting stroke can be adjusted, the device is suitable for endurance tests of return springs of miter saws with different shapes and sizes. Moreover, the device has a simple structure and is reliable to control.
Description
Technical field
The utility model relates to electric tool returning spring long duration test equipment, particularly a kind of cylinder type spring durability test device that is applicable to the long duration test of mitre saw class handle for tool returning spring.
Background technology
As everyone knows, the mitre saw product that exports to EU member country must meet the EN61029-2-9:2002 standard-required, when mitre saw is finished cutting, remove when pressing down external force, should be able to be returned to rest position from maximum depth of cut automatically, as adopt compression spring to reply, and this spring should be able to bear 10000 times compression and answer long duration test, and can not rupture also can keep normal restoring force.T ü V, authentications such as GS, GE also have returning spring long duration test project demand to mitre saw, but present China does not still have the checkout equipment of this project maturation, so a kind of difformity size mitre saw returning spring durability test apparatus that is applicable to of market in urgent need.
Summary of the invention
In order to solve above-mentioned mitre saw returning spring long duration test problem, the utility model provides a kind of cylinder type spring durability test device, employing pressurized air is power, have installation site and actuating length adjustable structure, be applicable to the long duration test of difformity size mitre saw returning spring, simple structure, control is reliable.
The scheme that the utility model adopted is:
The cylinder type spring durability test device mainly is made up of base plate, column, cylinder assembly, cylinder location adjusting part and control box, and described cylinder assembly is pressed hand, fixation steel plate, formed near switch, cylinder and cylinder stroke limit nut by simulation; Described cylinder location adjusting part is made up of cylinder up-down adjustment plate, cylinder angle and front and back adjustable plate, cylinder left and right adjusting plate.Described column is connected with described base plate is vertical, and described cylinder up-down adjustment sleeve-board is gone into described column, and can move up and down along described column, and described cylinder is connected with described cylinder location adjusting part.Described cylinder angle and front and back adjustable plate utilize arc-shaped hole and kidney shape hole, realize that the adjusting of described cylinder mounted angle and front and back position is fixed; Described cylinder left and right adjusting plate adopts kidney shape hole, regulates the position, the left and right sides of described cylinder, so that described simulation presses gloves to go in the handle of mitre saw, finishes the action of depressing and lifting the mitre saw handle; The polylith pressing plate is arranged on the described base plate, have kidney shape hole on the described pressing plate, can use the mitre saw of bolt difformity size.According to difformity size mitre saw depress and lift extreme position, regulate the timing relay delay time of described cylinder stroke limit nut and described control box, make described simulation press hand reliably to contact with the handle of mitre saw depressing and lift in the process.The delay time that press during described control box is mainly realized testing and lift the number of times setting recording, presses down is set and the commutation of gas circuit two-position four-way valve, realizes moving up and down of piston.Described fixation steel plate sent electric signal control two-position four-way valve commutation by described near switch near described near switch when handle lifted, and piston is pressed down.Arrive when piston presses down delay time, the timing relay action makes on the piston and lifts.Described cylinder stroke limit nut is to guarantee throw of poston in specialized range, and when it ran into described cylinder, piston can not press down, and presses hand and mitre saw handle not to break away to guarantee described simulation.
The beneficial effects of the utility model are:
The cylinder type spring durability test device is simple in structure, regulates flexiblely, and the requirement of outlet mitre saw returning spring long duration test relevant criterion is satisfied in the mitre saw returning spring long duration test of applicable difformity size, and can realize unmanned work.
