Abstract
Disclosed is a fatigue testing machine for vertical force of a bicycle frame, and the fatigue testing machine comprises a base plate, a front fixed seat and a rear fixed seat that are vertically installed on the base plate. The central part of the rear fixed seat is connected to a simulation seat tube. One end of the simulation seat tube is connected to the bicycle frame. The front fixed seat is connected to one end of a simulation front fork and the other end of the simulation fork is connected to the bicycle frame. The bottom of the front fixed seat is equipped with a screw rod while the top end of the front fixed seat is equipped with an air cylinder. A force sensor is connected between the air cylinder and the simulation seat tube. The rear fixed seat bearing the air cylinder is adjusted to a predetermined height by shifting the screw rod. The air cylinder is operated to transmit pressure to the force sensor and then to the simulation front fork. Since the simulation front fork and the bicycle frame are connected together, force is transmitted to the bicycle frame to achieve anti-fatigue testing of the bicycle frame. The situation is changed that the height of the air cylinder is adjusted with the aid of other auxiliary parts in the prior art, and therefore testing efficiency of the bicycle frame is improved.
Description
Technical field
The utility model relates to cycle frame testing apparatus field, is specifically related to a kind of cycle frame vertical force fatigue tester.
Background technology
Bicycle is as a kind of daily vehicles, and the characteristics of its environment protection health are subjected to people's favor day by day, so people are also more and more higher to the security requirement of bicycle.Vehicle frame is as the main composition parts of bicycle, and its performance height is to the safe decisive role of bicycle, and checkout equipment detects and the height of performance need rely on accurately.Chinese patent Granted publication CN 201229238Y discloses a kind of comprehensive tester for cycle frame, fatigue durability by the air cylinder detecting vehicle frame, but because can not carrying out height freely, regulates in cylinder, cause when the vehicle frame of test different model, need finishing by auxiliary member, influence testing efficiency.
Summary of the invention
For solving the problems of the technologies described above, we have proposed a kind of cycle frame vertical force fatigue tester, adjust by the position to cylinder, and increase screw mandrel in the bottom of preceding holder, to realize freely adjusting the cylinder height, promote the purpose of the detection efficiency of vehicle frame.
For achieving the above object, the technical solution of the utility model is as follows:
Cycle frame vertical force fatigue tester, comprise base plate, vertically be installed on preceding holder and back holder on the described base plate, the middle part of described back holder connects vacation and shows saddle pipe, described vacation shows that an end of saddle pipe is connected with vehicle frame, holder shows that with false an end of front fork is connected before described, described vacation shows that the other end of front fork is connected with described vehicle frame, screw mandrel is equipped with in the bottom of holder before described, cylinder is equipped with on the top of holder before described, and described cylinder and described vacation are shown and be connected with strength sensor between the saddle pipe.
Further, the top outside surface of described preceding holder is provided with scale.
The beneficial effect of the technical program is: the preceding holder that moves the carrying cylinder by screw mandrel is adjusted to both take the altitudes, cylinder operation can reach strength sensor with pressure, and then reach vacation and show front fork, because vacation shows that front fork links to each other with vehicle frame, thereby realize the power conduction to vehicle frame, vehicle frame is realized the endurance test, changed the height that to adjust cylinder in the prior art by other auxiliary members, promoted the detection efficiency of vehicle frame.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the vertical section structure synoptic diagram of the utility model embodiment 1 disclosed cycle frame vertical force fatigue tester.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
Embodiment
As shown in Figure 1, cycle frame vertical force fatigue tester, comprise base plate 6, vertically be installed on preceding holder 5 and back holder 7 on the described base plate 6, the middle part of described back holder 7 connects vacation and shows saddle pipe 8, described vacation shows that an end of saddle pipe 8 is connected with vehicle frame 9, holder 5 shows that with false an end of front fork 3 is connected before described, described vacation shows that the other end of front fork 3 is connected with described vehicle frame 9, screw mandrel 4 is equipped with in the bottom of holder 5 before described, cylinder 1 is equipped with on the top of holder 5 before described, and described cylinder 1 and described vacation are shown and be connected with strength sensor 2 between the saddle pipe 8.
By adjusting the displacement of screw mandrel 4, the preceding holder 5 of carrying cylinder 1 can be adjusted to both take the altitudes, cylinder 1 running can reach pressure strength sensor 2, and then reach vacation and show front fork 3, because vacation shows that front fork 3 links to each other with vehicle frame 9, therefore strength sensor 2 conducts to described vacation and shows that the pressure of saddle pipe 8 can form vertical forces to described vehicle frame 9, through repeatedly test, vehicle frame 9 is realized the endurance test, change the height that to adjust cylinder 1 in the prior art by other auxiliary members, promoted the detection efficiency of vehicle frame; Further, the top outside surface of holder 5 arranges scale before described, be conducive to control and observe described screw mandrel 4 in transmission to described strength sensor 2 applied pressure sizes, thereby further promote detection efficiency.
Above-described only is the preferred implementation of the utility model cycle frame vertical force fatigue tester; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. cycle frame vertical force fatigue tester, comprise base plate, vertically be installed on preceding holder and back holder on the described base plate, the middle part of described back holder connects vacation and shows saddle pipe, described vacation shows that an end of saddle pipe is connected with vehicle frame, and described preceding holder shows that with false an end of front fork is connected, and described vacation shows that the other end of front fork is connected with described vehicle frame, it is characterized in that screw mandrel is equipped with in the bottom of described preceding holder; Cylinder is equipped with on the top of holder before described, and described cylinder and described vacation are shown and be connected with strength sensor between the saddle pipe.
