Further, described adjustment rack is have one fixed width and the Y shape metal frame of horizontal positioned, two end arms up and down of described adjustment rack open at one end all and plane-parallel, and end arms contacts with the gauge head of described clock gauge on described adjustment rack, lower arm top is connected with contact head, and described contact head contacts with tested Inner annular wheel.

Further, be not dynamically connected above described fixed station 4 equal-sized rectangular metal blocks, and described derby relative to the arrangement of one-tenth V-shaped, has certain interval between often pair of described derby between two.

Further, be all embedded with the wolfram steel cylindrical rod contour with derby outside described each derby, it is inner that a described wolfram steel cylindrical rod part embeds derby, and a part exposes, and the arrangement mode of described wolfram steel cylindrical rod is identical with described derby arrangement mode.

Further, described clock gauge is connected with described second test desk by connecting link, and described connecting link is connected with described second test desk by adjusting nut.

Further, described clock gauge is vertical with described adjustment rack.

The beneficial effect that the utility model reaches:

Gear internal tooth pitch measurement device structure of the present utility model is simple, Y shape adjustment rack open at one end lower surface can put in gear internal, the contact head of adjustment rack lower end contacts with gear internal tooth, can record pitch of teeth in required gear by the reading of transmitting gear and clock gauge display, easy to use; When gear is placed on fixed station, on gear axial plane and fixed station, wolfram steel cylindrical rod is linear contact lay, contributes to reducing measuring error, improves measuring accuracy.

Accompanying drawing explanation

Fig. 1 is a kind of gear internal tooth pitch measurement device schematic diagram in the utility model embodiment;

Wherein: 1. base, 3. fixed station, 21. first test desks, 22. second test desk, 4. adjustment racks, 41. adjustment rack tail ends, 42. nuts, 5. clock gauge, 6. contact head, 7. derby, 8. wolfram steel cylindrical rod, 9. gauge head, 10. connecting link, 11. adjusting nuts.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.

In the utility model survey pitch and refer to upper tooth pitch/2 of gear compound graduation circle.

As shown in Figure 1, a kind of gear internal tooth pitch measurement device, comprise base 1, fixed station 3, first test desk 21 and the second test desk 22, fixed station 3 is relative with the first test desk 21, and fixed station 3, first test desk 21 and the second test desk 22 are all fixedly connected with base 1, first test desk 21 upper end is connected with adjustment rack 4, second test desk 22 top connects clock gauge 5, and adjustment rack 4 can swing up and down around the tie point of adjustment rack 4 and the first test desk 21, contacts with the gauge head of clock gauge during plane-parallel 5 when adjustment rack is rocked to adjustment rack 4.

Preferably, adjustment rack 4 is for having one fixed width and the Y shape metal frame of horizontal positioned, two end arms up and down of adjustment rack 4 open at one end all and plane-parallel, and end arms contacts with the gauge head 9 of clock gauge on adjustment rack 4, lower arm top is connected with contact head 6, contact head contacts with tested Inner annular wheel, pins adjustment rack tail end 41 and can realize swinging up and down of whole adjustment rack 4.The preferred first test desk upper end of the present embodiment is provided with groove, and the tail end of adjustment rack 4 is put into this groove and is connected with the first test desk by nut.
