Abstract

The utility model discloses a handle fatigue test machine. The handle fatigue test machine comprises a handle clamping device, a drive rod, a motor, a cam, a rail matched with the drive rod in movement, and a table top used for arranging a sample to be tested. The handle clamping device is connected with one end of the drive rod, the other end of the drive rod is matched with the profile of the cam, and the cam is fixed to an output shaft of the motor. Shortcomings in the prior art are overcome, lifting and lowering movements are achieved through the driving of the cam, lifting and lowering heights are fixed, hardly any errors exist, shaking cannot be generated during the test process, and different test speeds can be achieved by adjusting the rotating speed of the motor. Meanwhile, the handle fatigue test machine is applied to tests of pan products of a single panhandle and double panhandles, and can test multiple sets of pan products at the same time, so that high standard and high efficiency are really achieved.

Background technology

At standard C OOKWARE MAUNFACTURERS ASSOCIATION:2012(clause 3.3.5FATIGUE RESISTANCE OF WELDMENTS ANDHANDLE FIXTURING), and EN12983-1:2000COOKWARE-DOMESTIC COOKWARE FOR USE ON TOP OF A STOVE, COOKER OR HOB – PART1:GENERAL REQUIREMENTS(appendix A nnex E), also have EN13834:2007COOKWARE – OVENWARE FOR USE IN TRADITIONAL DOMESTIC OVENS(appendix A nnex B) in, need to carry out fatigue strength test to the handle of pot products, allow pot products in the situation that of 1.5 times of loads, controlling pot handle plays pot integral end to promote 40mm, then put down, thereby carry out testing fatigue 15000 times, and in above-mentioned standard, do not mention the device for this test.

At present, be mostly mode by hand-operated lifting or air pump lifting to realize the object of above-mentioned test, but these two kinds of methods have its drawback.First, test by hand-operated lifting method, waste of manpower, tests inaccurately, and lifting height and speed are difficult to guarantee.Secondly, adopt air pump elevating method to test, in air pump decline process, have a slight jitter, can make handle stressed suddenly with pot body, increased the weight of the stressed of handle, can affect the accuracy of test net result.

Utility model content

For solving existing problem in above-mentioned prior art, the utility model provides a kind of handle fatigue tester, can realize stable automatic lifting, has guaranteed the accuracy of test, has improved the efficiency of test.

The utility model adopts following technical scheme to realize: a kind of handle fatigue tester, comprises the track of handle clamping device, drive link, motor, cam, the motion of cooperation drive link and for placing the table top of testing sample; Described handle clamping device is connected with one end of described drive link, and the other end of described drive link is engaged on the profile of described cam, and described cam is fixed on the output shaft of described motor.

Preferably, also comprise conversion clamping device, described conversion clamping device comprises selector bar, connecting link and two hooks, and described selector bar is engaged in described handle clamping device, described connecting link is fixed on described selector bar, and described hook is fixed on described connecting link.

Preferably, also comprise the variable length link that regulates horizontal position, described variable length link one end is fixedly connected on described handle clamping device, the described variable length link other end is fixedly connected on described drive link, by regulating the length of described variable length link can change the angle that handle clamping device and horizontal level form, thereby the bottom of a pan of can adjusting handle out-of-level pot products coordinates with table top.

Preferably, described handle clamping device comprises handwheel, screw rod, stationary fixture, floating holder, guide rail and base, described stationary fixture is fixed on described base, described guide rail is fixed on described base, described floating holder is slidably connected on described guide rail, on described floating holder, offer and coordinate described screw flight hole, described screw rod one end is fixedly connected with described handwheel, the other end is fixedly connected with described stationary fixture, described screw rod and described guide rail parallel.

Preferably, described handle fatigue tester can be made up of above-mentioned each parts of twice or many times the handle fatigue tester of double or multistation.

Compared with prior art, the utlity model has following beneficial effect: this device has overcome the shortcoming of prior art, realize rising, down maneuver by cam driven, adjustable height immobilizes and almost there is no error, test process can not produce shake, can realize different test speeds by the rotating speed that regulates motor, is suitable for the test of the pot products of single panhandle, two panhandles simultaneously, once can test many cover pot products simultaneously, really realize high standard, high-level efficiency!

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with specific embodiment, a kind of handle fatigue tester of the utility model is described in further detail.

As shown in Figure 1, the utility model proposes a kind of handle fatigue tester, comprise handle clamping device 1, conversion clamping device 2, drive link 3, coordinate drive link motion track 4, regulate the variable length link 5 of horizontal position, for placing adjustable platform 6, motor and the cam of testing sample; Handle clamping device 1 comprises handwheel 101, screw rod 102, stationary fixture 103, floating holder 104, guide rail 105 and base 106, stationary fixture 103 is fixed on base 106, guide rail 105 is fixed on base 106, floating holder 104 is slidably connected on guide rail 105, on floating holder 105, offer the threaded hole that coordinates screw rod 102, screw rod 102 one end are fixedly connected with handwheel 101, the other end is fixedly connected with stationary fixture 103, and screw rod 102 is parallel with guide rail 105; Base 106 belows are fixedly connected on one end of drive link 3, and the other end of drive link 3 is engaged on the profile of cam, and cam is fixed on the output shaft of motor, and driven by motor cam rotates and then drives drive link to move up and down in track 4; Variable length link 5 one end are fixedly connected with drive link 3, the other end is fixedly connected with base 106; Conversion clamping device 2 comprises selector bar 201, connecting link 202 and two hooks 203, and connecting link 202 is fixed on selector bar 201, and hook 203 is fixed on connecting link 202, and selector bar 201 is fixed in stationary fixture 203 and floating holder 104.
