Description of the drawings:
fig. 1 is a structural diagram of the present invention.
Fig. 2 is a structural diagram of the center pillar of the present invention.
Fig. 3 is a structural diagram of the middle slider of the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 3, the utility model relates to a spraying stretching device for spring processing on automobile brake, including fixed plate 11, stand 12, arm-tie 13, slider 21, pin 22, guide arm 31, bottom plate 32, push pedal 33 and pneumatic cylinder 34, adjusting screw 41 and adjusting nut 42.
Two vertical fixed connection of stand 12 are on fixed plate 11, and bottom plate 32 level fixed connection is in the bottom of two stand 12, sliding connection a slider 21 on every stand 12, and the both ends fixed connection of arm-tie 13 is on two sliders 21, and arm-tie 13 level arranges. The guide rod 31 is vertically inserted on the bottom plate 32, the top end of the guide rod 31 is fixedly connected with the pulling plate 13, the bottom end of the guide rod 31 is fixedly connected with the pushing plate 33, the hydraulic cylinder 34 is fixedly connected on the bottom plate 32, and the output shaft of the hydraulic cylinder 34 is arranged above the pushing plate 33.
A plurality of adjusting screws 41 are connected to the fixing plate 11 in parallel and vertically in a threaded manner, each adjusting screw 41 is connected with an adjusting nut 42 in a threaded manner, the adjusting screw 41 is fixed on the fixing plate 11 by the adjusting nut 42, a hanging hole is formed in the bottom end of each adjusting screw 41, and a hanging lug 131 is arranged on the upper end face of the pulling plate 13 and is positioned under each adjusting screw 41. The adjusting screw 41 has a T-bar configuration.
The upright post 12 is provided with a plurality of locking holes 121 which are arranged in a layered manner, the hole opening of each locking hole 121 is inclined downwards, the slider 21 is provided with an insertion hole 211, the hole opening of each insertion hole 211 is inclined downwards and has the same inclination angle as that of the locking hole 121, and the pin 22 penetrates into the locking hole 121 through the insertion hole 211.
The utility model provides a slider 21 is the U-shaped structure, and slider 21's U-shaped groove sliding connection all is equipped with a jack 211 on two sides that are parallel to each other in slider 21 on stand 12.
The upright 12 is provided with a rectangular rod structure. The upright post 12 is matched with the U-shaped groove of the sliding block 21 to ensure the stability of sliding.
In order to facilitate the pin 22 to be clamped in the locking hole 121, an arc clamping groove 122 is formed on a groove wall at the top end of the locking hole 121.
Before use, the pin 22 is firstly pulled out from the slide block 21, and when the tension spring is used for painting, two ends of the tension spring are respectively connected to the connecting lugs of the fixed plate 11 and the pulling plate 13. When the tension spring needs to be stretched, the output shaft of the hydraulic cylinder 34 extends out and pushes the push plate 33 to move downwards, and the push plate 33 drives the pull plate 13 to move downwards, so that the tension spring is stretched. After the extension spring is stretched, the spring force of the retraction of the extension spring can be reacted to the hydraulic cylinder 34, in order to avoid the spring force being reacted to the hydraulic cylinder 34, the pin 22 is inserted into the locking hole 121 along the insertion hole 211 at the moment, then the output shaft of the hydraulic cylinder 34 is retracted, and the push plate 33 loses the thrust of the hydraulic cylinder 34. At this time, the tension spring will retract and drive the pulling plate 13 to move upward, and at this time, the insertion hole 211 on the pin 22 pushes the pin 22 into the circular arc catching groove 122 at the top end of the locking hole 121. The output shaft of the hydraulic cylinder 34 continues to retract, avoiding the spring force to react against the hydraulic cylinder 34.
After the paint spraying of the tension spring is finished, when the tension spring is taken down, the output shaft of the hydraulic cylinder 34 extends out and is abutted against the push plate 33, and when the push plate 33 is pushed to move downwards, the pin 22 automatically slides down along the insertion hole 211 due to the self gravity. Then the output shaft of the hydraulic cylinder 34 retracts to the initial position, and at the moment, the tension spring returns to the unstretched state, and then the tension spring can be taken down.
When the tension springs with different lengths and models are used, the position of the adjusting screw rod 41 is adjusted to enable the tension springs to be suitable for the tension springs with different lengths.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
