Abstract
The invention provides a backlash detecting device, which comprises a workbench, wherein a gear horizontal positioning pin device and a cylindrical position pin are arranged on the workbench, a standard gear is sleeved on the a cylindrical position pin and is positioned circumferentially through the gear horizontal positioning pin device, wherein a gear to be measured is embedded in the workbench and is in backlash connection with the standard gear; and one end of a dialgauge is fixed to the workbench, a detection head at the other end of the dialgauge contacts a backlash of the gear to be measured. In the backlash detecting device, the gear to be measured is adopted to simulate the state of the matching with the standard gear, the gear to be measured contacts two tooth surfaces of the standard gear in a mode of circumferential rotation, the rotation distance of the gear to be measured is the backlash, the dialgauge is fixed to the workbench, the rotation distance of the gear to be measured is detected; and therefore, the aim of detecting the backlash is achieved, the effect of artificial factors is prevented, and the backlash detecting device has the advantage of accurate detection data.
Description
Technical field
The present invention relates to a kind of pick-up unit, especially a kind of backlash detecting device.
Background technology
Gear is the important component part in the drive mechanism, and the quality of its quality directly has influence on the quality of transmission effect.So in the manufacture process of gear, all require gear is realized full inspection, so that quality of control gear better.Traditional detection method is with the backlash spacing on the Centigrade scale prototype gear at present, artificial reading and record, and 1 time that gear spent of every detection is longer; Its detection efficiency is low; Be difficult to catch up with the beat of production line during online production, and, receive the influence of environment and artificial factor easily owing to be artificial reading; Cause the detection architecture out of true, so be difficult to satisfy the requirement that accurately detects.
Summary of the invention
The purpose of this invention is to provide a kind of backlash detecting device, backlash detecting device a kind of simple in structure, easy to detect particularly is provided.
Technical scheme of the present invention provides a kind of backlash detecting device; Comprise worktable (10); Said worktable (10) is provided with gear located lateral pin assembly (12) and cylindrical register pin (15), and a master gear (14) is socketed on the cylindrical register pin (15), and circumferentially locatees through gear located lateral pin assembly (12); It is characterized in that: a gear to be measured (16) cover is embedded on the worktable (10); With said master gear (14) backlash clamping, a Centigrade scale (20) one ends are fixed in worktable (10), and the Centigrade scale detection head (18) of the other end touches with the backlash of gear to be measured (16).
Preferably, said worktable is provided with track, and said gear located lateral pin assembly (12) lower end is removably set in the said worktable track.
Preferably, said gear located lateral pin assembly (12) is through being bolted in the said worktable track.
Backlash detecting device of the present invention owing to adopt gear die to be measured to intend the master gear mated condition, contacts circumferential rotation of gear to be measured with two flank of tooth of master gear; The distance of its rotation also is backlash; Centigrade scale is fixed in worktable, through detecting gear rotation distance to be measured, thereby reaches the purpose that detects backlash; Avoid the influence of artificial factor, have accurately advantage of the data of detection.
Description of drawings
Fig. 1 is that the master of the backlash detecting device of preferred embodiment of the present invention looks synoptic diagram;
Fig. 2 is the schematic top plan view of the backlash detecting device of preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Like Fig. 1, shown in Figure 2, this backlash detecting device comprises worktable 10; Be movably arranged on the gear located lateral pin assembly 12 on the worktable 10; Be vertically fixed on the master gear 14 on the worktable 10, gear 16 to be measured, Centigrade scale detection head 18 and Centigrade scale 20; Wherein, master gear 14 is connected with gear 16 backlash to be measured.Gear located lateral pin assembly 12 insertion master gears 14 are fixed and prevent its circumferential rotation, and are connected with worktable 10 through bolt.Centigrade scale 20 1 ends are fixed on the worktable 10, and its Centigrade scale detection head 18 contacts with 16 of gears to be measured.Before the use, Centigrade scale is carried out the calibration of zero-bit with a master gear.Gear 16 to be measured rotates in a circumferential direction; It is contacted with two flank of tooth of master gear 14; The turned position of gear to be measured shows on Centigrade scale 20 through the form of Centigrade scale detection head 18 with numeral, this numerical value be gear to be measured 16 and master gear gap width.The testing staff judges that according to this numerical value whether qualified gear to be measured 16 is.
The above is merely embodiment of the present invention.Protection scope of the present invention is not limited thereto, and any technician who is familiar with the present technique field is in the technical scope that the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
