Abstract
The utility model provides a belt rate of tension detection device which characterized in that: the device comprises a pressing plate with a central hole, a guide cylinder fixed on the pressing plate and communicated with the central hole, a pressing rod with a limiting boss and an external thread at the lower end and the upper end respectively, a limiting nut matched with the external thread, and a reset spring sleeved on the pressing rod, wherein a rod part of the pressing rod is provided with a detection mark and sequentially penetrates through the central hole and the guide cylinder from bottom to top, and two ends of the reset spring respectively support against the guide cylinder and the limiting nut. The utility model discloses simple structure, low in manufacturing cost, convenient to use, detection are accurate, can judge whether belt tension accords with the technological requirement directly perceivedly through locating the detection mark on the depression bar.
Description
Technical field
The utility model relates to the pick-up unit of belt tightening, especially relates to a kind of pick-up unit of belt tightening of detection of engine belt pulley.
Background technology
Being provided with of belt tightening need meet technologic requirement, should satisfy when applying the pressure of 100N in the belt centre position like the belt tightening of engine belt pulley, and its degree of disturbing changes the technological requirement between 8mm and 12mm.For this reason, need badly a kind of special detection device that is used to judge belt tightening is provided.
Summary of the invention
The purpose of the utility model be for overcome above-mentioned deficiency provide a kind of simple in structure, low cost of manufacture, easy to use, detect belt tightening pick-up unit accurately.
The utility model is realized like this: a kind of belt tightening pick-up unit; It is characterized in that: comprise the pressing plate that is provided with center pit, be fixed on the pressing plate and be respectively equipped with positive stop lug boss and externally threaded depression bar, the stop nut that cooperates with external thread, be enclosed within the back-moving spring on the depression bar with guide cylinder, lower end and upper end that center pit connects; The bar portion of said depression bar is provided with certification mark and passes center pit and guide cylinder from the bottom to top successively, and the two ends of said back-moving spring are withstood guide cylinder and stop nut respectively.
The upper end of said depression bar also is provided with the installation nut that is used for fixing dynamometer.
One side of said pressing plate also is provided with the reinforcement that is used to prevent the distortion of pressing plate reference field.
One end of said pressing plate bottom surface also is provided with the draw-in groove that is used for fixing pressing plate.
The height of said positive stop lug boss is identical with the thickness of pressing plate, and the diameter of positive stop lug boss is greater than the internal diameter of guide cylinder, less than the diameter of center pit.
The utility model can be judged whether according with process requirements of belt tightening intuitively through being located at certification mark on the depression bar.Have simple in structure, low cost of manufacture, easy to use, detect characteristic of accurate.
Description of drawings:
Accompanying drawing 1 is the structure and the assembling synoptic diagram of the utility model.
Among the figure: 1---pressing plate (11---center pit), 2---guide cylinder, 3---depression bar (31---positive stop lug boss, 32---external thread, 33---certification mark), 4------back-moving spring, 6---is installed nut, 7---reinforcement, 8---draw-in grooves to stop nut, 5.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing 3 with embodiment.
Embodiment: comprise the pressing plate 1 that is provided with center pit 11, thickness is 3mm, and a side of pressing plate 1 is provided with reinforcement 7; Be used to prevent its reference field distortion, an end of pressing plate 1 bottom surface also is provided with the draw-in groove 8 that is used for fixing pressing plate 1, and guide cylinder 2 is welded on the pressing plate 1 and with center pit 11 and connects; Comprise that also the lower end is provided with positive stop lug boss 31 and upper end car depression bar 3, the stop nut 4 that cooperates with external thread 32 of external thread 32 arranged, is enclosed within the back-moving spring 5 on the depression bar 3; The height of positive stop lug boss 31 is identical with the thickness of pressing plate 1, and diameter is greater than the internal diameter of guide cylinder 2, less than the diameter of center pit 11; The bar portion of depression bar 3 is provided with certification mark 33 and passes center pit 11 and guide cylinder 2 from the bottom to top successively; Overlap upper reset spring 5 then, the stop nut 4 of screwing on again, the two ends of back-moving spring 5 are withstood guide cylinder 2 and stop nut 4 respectively; Be used for measuring the reset response that finishes, the upper end of depression bar 3 also is screwed with the installation nut 6 that is used for fixing dynamometer.Promptly become the utility model.
During use, existing draw-in groove 8 is blocked wheel hub, make pressing plate 1 be close to belt and place, dynamometer is placed the upper end of depression bar 3 through nut 6 is installed, exert pressure then, confirm whether requirement up to specification of belt tightening through the position of observing certification mark 33.
