Technical Field
The utility model relates to a tension spring detection device.
Background
The traditional tension spring detection device is characterized in that one end of a tension spring is fixed on a fixing device through a positioning pin, then the other end of the tension spring is pulled through a digital display push-pull dynamometer, and detection of the tension spring is achieved, but the tension spring force with the maximum measuring range of 500N can only be tested generally in the mode, and tension springs with thicker diameters and larger force cannot be detected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an extension spring detection device is provided, detectable extension spring power is bigger.
The utility model adopts the technical proposal that: a tension spring detection device comprises a base, a fixed rod fixed on the base, a guide rod sleeved in the fixed rod and a rotary rod rotatably arranged on the fixed rod; the upper end and the press cooperation of guide bar, the one end of dwang and the lower extreme cooperation other end of guide bar are connected with the spring upper end of waiting to detect, and the lower extreme and the dead lever of spring are connected.
Further, one side of dead lever is equipped with installation pole and installation pole down, the rotary rod rotates through the pivot and sets up on last installation pole, and the lower extreme and the installation pole down of spring are connected.
Further, go up installation pole and installation pole down and be two of parallel arrangement, the rotary rod setting is before two installation poles, and the lower extreme of spring is installed between two installation poles down.
Furthermore, the bottom end of the guide rod is convex, and one end of the rotating rod is matched with the convex part of the guide rod.
Furthermore, the fixing rod is provided with a T-shaped groove, and the cross section of the guide rod is in a corresponding T-shaped block shape.
The utility model discloses an actively the effect does: the utility model discloses replace traditional vertical line push-and-pull dynamometer with the press, increased the test range of spring force, and ingenious utilization moment balance principle, through the displacement of measuring the extension spring and the data of press display, can convert out the pulling force of extension spring and the corresponding relation of displacement, test out the data of extension spring power indirectly.

fig. 2 is the schematic view of the fixing rod and the guide rod of the present invention.
Detailed Description
As attached figure 1, 2, the utility model discloses a base 2, vertical dead lever 3, the guide bar 1 of sliding sleeve setting in dead lever 3 and rotating the rotary rod 6 that sets up on dead lever 3 through pivot 8 of fixing on base 2, the one end of rotary rod 6 cooperatees with the bottom of guide bar 1, and one end is connected with the upper end of waiting to detect spring 7 in addition, and pivot 8 is located the middle part position, utilizes the push down of guide bar 1 one end to lift the other end. The bottom end of the guide rod 1 is convex, and the rotating rod 6 is matched with the convex part.
Be equipped with on the lateral wall of dead lever 3 and install pole 5 and install pole 4 down, go up installation pole 5 and install pole 4 down and all be two of parallel arrangement, rotary rod 6 is located and installs between the pole 5 on two, and the both ends of pivot 8 and two are gone up the cooperation of installation pole 5, are equipped with the peg in rotary rod 6 and the cooperation department of extension spring 7, and the upper end of extension spring 7 is hung on the peg. A hanging rod is also arranged between the two lower mounting rods 4, and the lower end of the tension spring 7 is hung on the hanging rod at the position.
A T-shaped groove is arranged along the height direction of the fixed rod 3, and the transverse section of the guide rod 1 is in a T shape corresponding to the T-shaped groove. On dead lever 3 and with the one end of rotary rod 6 corresponding position department be equipped with cavity 9, the one end of rotary rod 6 stretches into in cavity 9 back, with the cooperation of guide bar 1 to the corresponding section end of rotary rod 6 can be in cavity 9 activity from top to bottom, in order to realize the extension to the spring. The top end of the guide rod 1 is connected with a press machine, and the corresponding end of the guide rod 1 is pressed down by the press machine, so that the tension effect on the tension spring is realized.
The utility model discloses utilize the press to transmit pressure for rotary rod 6 through guide bar 1, rotary rod 6 rotates through pivot 8 to pulling spring 7, through the displacement of measuring the extension spring and the numerical value of press display, the corresponding relation of pulling force and displacement of extension spring 7 is recalculated through the formula again. Because the pressure that the press can provide is great, and then conduct extension spring 7 through moment, in this embodiment, the range of the press is 0-5000N, can detect 0-2600N extension spring in theory.
The utility model discloses greatly increased extension spring's detection range to stable in structure, reliable, the commonality is good.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
