Abstract
The invention relates to a testing device for load of a jig saw, which is characterized in that the testing device comprises a load simulator (100), a jig saw fixing device and a frame (8), wherein the load simulator (100) comprises a mounting bracket (3), a magnetic powder clutch (4) and two rollers (1 and 2); the magnetic powder clutch (4) is arranged below the mounting bracket (3), and the output end of the magnetic powder clutch (4) is connected with the roller (2) through a one-way bearing; a cantilever of the jig saw fixing device is arranged at the outer side of the frame (8) and consists of a cantilever (5) and a fixing part (6); and a jig saw blade to be tested is arranged in a clearance between the two rollers and clamped by the two rollers. During the testing process of the jig saw, the load under actual conditions is simulated through the magnetic powder clutch and the one-way bearing completely, and the actual cutting material is not needed during the testing process, therefore the testing device has the characteristics that the testing efficiency is improved, the testing material is saved, the testing cost is reduced, and the operation is simple and convenient.
Description
Technical field
The present invention relates to a kind of coping saw load testing device.
Background technology
Nineteen forty-seven, in the world First sweep-saw has been invented by company of German Bosch (Bosch).Sweep-saw is a kind of a kind of electric reciprocating saw that can carry out by curve sawing, be again long-pending comb, vertical saw, its adapted curve saw blade, can carry out straight line and curve sawing to sheet materials such as timber, metal, plastics, rubber, leathers, also sharp blade can be installed, cut rubber, leather, fabric, polyfoam, cardboard etc.Sweep-saw is widely used in the industries such as automobile, boats and ships, furniture, leather, and more application is also arranged in wooden model, handicraft, setting, ad production, repairing trades.
The saw blade of sweep-saw is sandwiched on the sweep-saw, saw blade passes workpiece for sawing and moves up and down, usually the tooth of saw blade is forward, when therefore pressing forward cutting track work, can produce the reacting force of load, under the effect of described load, can occur tired and aging after saw blade works long hours, thereby cause the saw blade strength decreased, fracture.
Generally, for the performance to sweep-saw is tested, need to carry out operation at the material to be processed of reality with sweep-saw to be tested, this method of testing working strength is large, and can cause the waste of material, has increased the cost of test.
Summary of the invention
The purpose of this invention is to provide the coping saw load testing device that a kind of testing efficiency is high, easy and simple to handle, save test material, reduction testing cost.
Coping saw load testing device among the present invention, it is characterized in that: comprise load simulating device, sweep-saw stationary installation and frame, described frame is provided with opening on (8), and described load simulating device (100) is installed on the described frame (8) by described opening; Described load simulating device comprises erecting frame, powder clutch and two rollers; Described powder clutch is installed in the below of described erecting frame, and its output terminal links to each other with a described roller by unilateral bearing; Described sweep-saw stationary installation cantilever is arranged at the outside of described frame, is comprised of cantilever and fixed part; The saw blade of sweep-saw to be tested between described two rollers gap location and by described two roller clampings.
Described proving installation is being realized sweep-saw in the process of test, simulate load under the actual condition by described powder clutch and unilateral bearing fully, in the process of test, do not need to use real cutting material, thereby can improve testing efficiency, saving test material, reduction testing cost, have simultaneously characteristics easy and simple to handle.
Description of drawings
Fig. 1 is the structural drawing of load simulating device.
Fig. 2 is the structural drawing of coping saw load testing device.
Embodiment
Below in conjunction with accompanying drawing 1-2 technical scheme of the present invention is elaborated.
Described coping saw load testing device comprises load simulating device 100, sweep-saw stationary installation and frame 8.
Described load simulating device 100 comprises erecting frame 3, powder clutch 4 and roller 1,2; Described powder clutch 4 is installed in the lower end of described erecting frame 3, and its output terminal links to each other with described roller 2 by unilateral bearing, and described unilateral bearing can only freely rotate in a direction, and can not rotate in another direction.Leave the gap between the described roller 1 and 2, during test, the saw blade of sweep-saw to be tested is arranged in described gap, by described roller 1 and 2 clampings.Described load simulating device 100 is installed on the described frame 8 by the opening on the described frame 8.
In the outside of described frame 8, cantilever is provided with described sweep-saw stationary installation; Described stationary installation is comprised of the fixed part 6 of a cantilever 5 and Y type; The axis direction of described cantilever 5 has an elongated slot, and described fixed part 6 is fixed on the described elongated slot slidably, in order to according to the needs of different sweep-saws the distance between sweep-saw and the described load simulating device 100 is regulated.
Because the sweep-saw broached-tooth design, when sweep-saw was worked, saw blade moved reciprocatingly along cut direction, during one of them direction motion, the effect of the negative broaching load of the saw blade of described sweep-saw, when to another direction motion, described saw blade is in free state.
Therefore, the resistance that the present invention utilizes described powder clutch 4 to produce comes the load that is subject in the real work of simulation curve saw, the characteristics of utilizing simultaneously unilateral bearing freely to rotate to a direction are come the free state that be not subjected to load of simulation curve saw on another direction.
When test, sweep-saw is placed on the described fixed part 6, after its saw blade passes a back up pad 7 with through hole, by described two rollers 1 and 2 clampings.When sweep-saw is started working, load and the situation of change thereof under actual working state by described powder clutch 4 and unilateral bearing simulation curve saw, thereby the indexs such as intensity to sweep-saw are tested, in this way, thus can improve test efficient, save the traditional test process need and use authentic material to test to cause a large amount of wastes, technical matters that testing cost is high.
Claims (5)
1. coping saw load testing device, it is characterized in that: comprise load simulating device (100), sweep-saw stationary installation and frame (8), described frame is provided with opening on (8), and described load simulating device (100) is installed on the described frame (8) by described opening; Described load simulating device (100) comprises erecting frame (3), powder clutch (4) and two rollers (1,2); Described powder clutch (4) is installed in the below of described erecting frame (3), and its output terminal links to each other with a described roller (2) by unilateral bearing; Described sweep-saw stationary installation cantilever is arranged at the outside of described frame (8), is comprised of cantilever (5) and fixed part (6); The saw blade of sweep-saw to be tested between described two rollers gap location and by described two roller clampings.
