Abstract
The invention relates to a handheld device for testing durability of a circular saw protective cover, which is characterized by comprising a rack and a workbench fixed on the top part of the rack, wherein a collision block, a guide pillar, an air cylinder and a test installation table are arranged on the workbench, the collision block, the guide pillar and the air cylinder are fixed on the workbench; the test installation table is slidably arranged on the guide pillar; and a piston of the air cylinder is connected with the test installation table so as to drive the test installation table to move towards a direction close to or far away from the collision block along the guide pillar. The handheld device for testing the durability of the circular saw protective cover has the characteristics that the structure is simple and reliable, the cost is low, a testing process is closer to an actual operation condition, and the closed reset time of the circular saw protective cover can be detected in the testing process.
Description
Technical field
The present invention relates to the proving installation of annular saw endurance quality, particularly relate to a kind of proving installation that is used to detect hand-held circular saw protective cover endurance quality.
Background technology
The protective cover of hand-held circular saw is an important safety protecting component of electric tool, operating personnel is played the protective effect that prevents by accidental cuts.Annular saw in the course of the work, its protective cover often needs repeated open, closure, its security performance is great to the influence of the security performance of annular saw complete machine.Domestic and the international standard of foundation: annular saw is configured to do 90
oSawing is the circulation that the horizontal level protective cover is closed into complete opening repeatedly fully, is not less than 10 round-robin speed with per minute and discharges 50000 times, after the cycling, require protective cover closure fully, and closure time should be greater than 0.3 second.
Publication number is that the patent of CN101493382B discloses a kind of annular saw durability test apparatus for protection shield; But this device is not enough below still existing at present: 1) kinematic train is complicated; Adopt motor, speed reduction unit, gear drive, belt gear, chain transmission, so complex structure, cost are high; 2) the actual operating position of test process and annular saw is inconsistent; Annular saw generally is that operating personnel promote annular saw in actual use, when the annular saw protective cover hit in material to be processed (for example timber) last time; Protective cover is opening by material jack-up to be processed; When annular saw when material to be processed withdraws from, the protective cover auto-closing, thus play the effect of security protection; And the CN101493382B patent is to drive the collision block motion through chain, and collision block is opened protective cover when striking the annular saw protective cover, collision block during away from the annular saw protective cover protective cover close, therefore inconsistent with the practical operation situation.3) after the cycling, do not detect the function of protective cover closure time.
Summary of the invention
In order to solve the deficiency that above-mentioned prior art exists, the present invention provide a kind of simple and reliable for structure, cost is low, method of testing is more near the annular saw protective cover durable test device of practical operation situation.
The present invention realizes through following technical scheme:
Hand-held circular saw protective cover durable test device; The worktable that it is characterized in that comprising frame and be fixed on frame top; Said worktable is provided with collision block, guidepost, cylinder and test erecting bed; Collision block, guidepost, cylinder all are fixed on the worktable, and the test erecting bed is slidably mounted on the guidepost, the piston of cylinder be connected with the test erecting bed with drive the test erecting bed along guidepost towards approaching or move away from the direction of collision block.
Nearly step ground, described hand-held circular saw protective cover durable test device is characterized in that described guidepost is fixed on the worktable through holder.
Nearly step ground, described hand-held circular saw protective cover durable test device is characterized in that described test erecting bed is provided with anchor clamps, said anchor clamps are fixed on hand-held circular saw to be measured on the test erecting bed.
Nearly step ground, described hand-held circular saw protective cover durable test device is characterized in that described test erecting bed is provided with the electromagnetism instrument, said electromagnetism instrument is used for testing the reset time of annular saw protective cover from complete opening to complete closure.
Beneficial effect of the present invention is: simple in structure, reliable, cost is low, and test process can detect the closed reduction time of annular saw protective cover more near the practical operation situation in the test process.
Fig. 1 is the structural representation of annular saw testing apparatus of the present invention.
Fig. 2 is the structural representation of annular saw testing apparatus other direction of the present invention.
Among the figure: the 1-frame, the 2-worktable, the 3-collision block, the 4-guidepost, the 5-cylinder, 6-tests erecting bed, 7-holder, 8-anchor clamps, 9-electromagnetism instrument.
Below in conjunction with accompanying drawing the present invention is further specified.
Like Fig. 1, shown in 2; Annular saw protective cover durable test device of the present invention comprises frame 1 and the worktable 2 that is fixed on frame 1 top; Worktable 2 is provided with collision block 3, guidepost 4, cylinder 5 and test erecting bed 6; Collision block 3 is fixed on the worktable 2, respectively is provided with a guidepost 4 on the both sides of collision block 3, and guidepost 4 is fixed on the worktable 2 through holder 7; Test erecting bed 6 is supported on the guidepost 4 slidably, and the piston that is fixed on the cylinder 5 on the worktable 2 is connected with test erecting bed 6, and the to-and-fro movement of the piston through cylinder 5 drives tests erecting bed 6 to-and-fro movement on guidepost 4.
Test erecting bed 6 is provided with and is used for the anchor clamps 8 of clamping annular saw (not shown) to be measured, anchor clamps 8 through screw retention on test erecting bed 6.
Also be provided with on the test erecting bed 6 and be used for testing the annular saw protective cover electromagnetism instrument 9 of the reset time from complete opening to complete closure, electromagnetism instrument 9 preferably adopts the Hall electromagnetic component.
The test process of annular saw durable test device of the present invention is following:
1) annular saw to be tested is fixed on the test erecting bed 6 through anchor clamps 8;
2) start-up control cabinet, pre-set control corresponding parameter;
3) through switch board start-up control system; The piston of cylinder 5 begins to-and-fro movement; 6 to-and-fro movements of piston actuated test erecting bed; Thereby open protective cover when making annular saw protective cover bump collision block 3, close protective cover when leaving collision block 3, realize once circulation, the reset time of electromagnetism instrument 9 test annular saw protective covers in this process from complete opening to complete closure;
4) number of times or the reset time of test period annular saw protective cover from complete opening to complete closure that reaches setting, test stopped, and the number of times of record test and the reset time of annular saw protective cover during greater than time of requiring.
That describes in the foregoing description and the instructions just explains principle of the present invention; The technician of the industry should understand; The present invention is not restricted to the described embodiments; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
The part that other that the present invention relates to are not described is identical with prior art.
