Abstract
The invention relates to a coping saw load testing device which is characterized in that the testing device comprises a mounting rack (1), a magnetic powder clutch (2) and two rollers (6, 7). The magnetic powder clutch (2) is installed at the outer side of the mounting rack (1), with the output end (3) connected with the roller (6) through a unilateral bearing; and the saw blade of the coping saw to be tested is arranged in the clearance between the two rollers and is clamped by the two rollers. In the process of testing the coping saw, the testing device entirely employs the magnetic powder clutch and the unidirectional bearing to simulate the load under the practical working condition and no real cutting material is used in the testing process. Therefore, the testing device can improve the testing efficiency, save testing material and reduce the testing cost and is simple and convenient to operate.
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 is characterized in that: comprise erecting frame, powder clutch and two rollers; Described powder clutch is installed in the outside of described erecting frame, and its output terminal links to each other with a described roller by unilateral bearing, 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 coping saw load testing device.
Fig. 2 is the use constitutional diagram 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 erecting frame 1, powder clutch 2 and roller 6,7; Described powder clutch 2 is installed in the outside of described erecting frame 1, and its output terminal 3 links to each other with described roller 6 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 6 and 7, during test, the saw blade of sweep-saw 5 to be tested is arranged in described gap, by described roller 6 and 7 clampings.
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 2 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 5 is placed on the back up pad 8 with through hole, after the saw blade of sweep-saw 5 passes described through hole, by described two rollers 6 and 7 clampings.When sweep-saw 5 is started working, load and the situation of change thereof under actual working state by described powder clutch 2 and unilateral bearing simulation curve saw, thereby the indexs such as intensity to sweep-saw 5 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 (2)
1. a coping saw load testing device is characterized in that: comprise erecting frame (1), powder clutch (2) and two rollers (6,7); Described powder clutch (2) is installed in the outside of described erecting frame (1), its output terminal (3) links to each other with a described roller (6) by unilateral bearing, the saw blade of sweep-saw to be tested between two described rollers gap location and by two described roller clampings, described device comprises that also described back up pad (8) is provided with a plurality of mounting holes be used to regulating described sweep-saw installation site for the back up pad with through hole (8) of placing sweep-saw.
2. device as claimed in claim 1 is characterized in that: described powder clutch (2) and unilateral bearing are used for the load of simulation curve saw.
