Embodiment
Below in conjunction with accompanying drawing explanation, the utility model is described in further detail.
As Figure 1-3, a kind of gear positioning precision measuring equipment 1, be used for measuring gear set 90 to be measured, gear set 90 to be measured has comprised mutual the first meshing gear 91 and the second gear 92, and the first gear 91 is cross helical gear and is fixed on gear connecting link 93.Its main element also includes body 10, power source 20, the first angular encoder 30, gear positioning seat 40 and the second angular encoder 50, body 10 has comprised pedestal 11, height control part 12, pedestal 11 and mount pad 13 are located at height control part 12 tops, wherein mount pad 13 is U font and has two erection part 131, and assembled portion 132 is located at end face one side of mount pad 13.Thus, mount pad 13 can be moved up and down by relative pedestal 11 by height control part 12.
Power source 20 is motor in the present embodiment, is used for rotating the first gear 91, and it is stably fixed on assembled portion 132.Power source 20 has controller (not shown) and power output shaft 22, controller is for controlling the start of power source 20, power output shaft 22 through assembled portion 132 and be socketed two bearings 133 be assembled in erection part 131 one of them, 131 of another erection part are provided with coupling shaft 60 and bearing 133.In addition, the tip end projects of power output shaft 22 enters between two erection part 131, makes gear connecting link 93 two ends coaxially be connected in power output shaft 22 and coupling shaft 60.
The first angular encoder 30 is socketed in the power output shaft 22 of power source 20 and with its external end edge connection bearing 133.The first angular encoder 30 is for measuring the rotational angle of power output shaft 22, because power output shaft 22 and gear connecting link 93 are coaxial connection and the rotation of synchronizeing, therefore the first angular encoder 30 can obtain the rotational angle of the first gear 91.
Gear positioning seat 40 has holder 41, rotating disk 42, dwang bearing 44 and seat stand 45, wherein the second gear 92 can be socketed and be assembled on holder 41, holder 41 is coaxially connected in the top of rotating disk 42, rotating disk 42 has dwang (not shown) through dwang bearing 44 and be arranged at rotationally seat stand 45,45 of seat stands be arranged at pedestal 11 and relatively pedestal 11 move horizontally.Therefore, the second gear 92 can be synchronizeed and rotate with rotating disk 42.
The second angular encoder 50 is socketed on dwang and with its external end edge connection of rotating rod bearing 44, the second angular encoder 50 is for measuring the rotational angle of dwang, because the second gear 92 for synchronizeing rotation, therefore can obtain the rotational angle of the second gear 92 with dwang.
In use, when user's wish measurement dividing apparatus cogs the positioning precision of organizing, first user carries out the step of position regulation, utilize height control part 12 to adjust the height of the first gear 91, and utilize gear positioning seat 40 to adjust the second gear 92 horizontal range relative with the first gear 91, allow the first gear 91 and the second gear 92 all be positioned at same height and suitable horizontal range and allow the first gear 91 can be tight and meshing the second gear 92 successfully, after position regulation, user just can start to carry out metrology operation.
In metrology operation, user utilizes the controller of power source 20 to control power output shaft 22 and rotates and reach predetermined angular, the first angular encoder 30 being now socketed in power output shaft 22 will read the numerical value of rotational angle, and read numerical value is back to controller.And when power output shaft 22 turns to the process of this predetermined angular, the second gear 92 will be driven and and then rotate by the first gear 91, the synchronous rotation that drives rotating disk 42 dwangs, and make the second angular encoder 50 read an angle measurement numerical value, the angle numerical value that user just can measure according to first and second angular encoder 30,50, calculates the positioning precision of gear.User is follow-up can also repeat above-mentioned steps and utilize resulting data to calculate the location repeatable accuracy of gear.Therefore user just can judge quality and the performance of gear set 90 to be measured with location repeatable accuracy by the positioning precision of gear as index.And whole measurement process steps is simple and processing ease, so user can measure rapidly, and then can before gear set is assembled in to dividing apparatus, can test in advance and detect defective products, reduces the generation of defective products.
In sum, this new structure is simple, easy to use, can be fast and measure accurately the positioning precision of gear set.
The above is only a kind of embodiment of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some similar distortion and improvement, within these also should be considered as protection domain of the present utility model.
