Description

Technical Field

[0001] This utility model belongs to the field of cradle support rod production technology, and in particular relates to a cradle support rod angle measuring device. Background Technology

[0002] The cradle support rod is a key basic component of the yarn drafting device, serving as a mounting base and mechanical fulcrum for the spring cradle. During the production of the cradle support rod, a "V"-shaped groove needs to be cut into it. After cutting, the "V"-shaped groove must be inspected to ensure the reliability of the cradle support rod's quality. The "V"-shaped groove must not deflect axially, or the deflection must be within an acceptable range. The overall outer perimeter of the cradle support rod is cylindrical, making it impossible to measure it horizontally on a projector. Even with fixtures for fixation, it's impossible to guarantee that the "V"-shaped groove opening is vertically upward. Currently, there is a lack of effective measurement methods, leading to some cradle support rods that do not meet quality requirements flowing to downstream equipment manufacturers, posing a significant risk to downstream production. Utility Model Content

[0003] To address the above problems, this utility model provides a device for measuring the angle of a cradle support rod.

[0004] This utility model is implemented as follows: A cradle support rod angle measuring device includes a base. Positioning frames are vertically and symmetrically fixed on one side of the upper end of the base to define the position of the cradle support rod. The positioning frames are arranged parallel to each other and have a "F"-shaped structure. Positioning blocks are fixedly installed at the lower part of the upper end of each positioning frame. The lower end of each positioning block is inclined upwards and abuts against the cutouts at both ends of the cradle support rod, defining the position of the upper parts of both ends of the cradle support rod. Base blocks are symmetrically fixed on the base between the positioning frames, with the middle of the upper end of each base block vertically fixed. A limiting post is used to restrict the position of the spring and prevent it from deflecting. A spring is fitted onto the limiting post, and a sleeve is tightly fitted onto the base block. The sleeve moves up and down along the base block. An end cap is horizontally fixed to the upper end of the sleeve. The two ends of the spring abut against the base block and the end cap. When the end cap moves the sleeve downwards under force, it compresses the spring. After the force on the end cap is removed, the end cap and sleeve move upwards under the spring force. When the spring is in the extended state, the lower part of the sleeve is connected to the base block, preventing the sleeve from separating from the base block under normal conditions.

[0005] The horizontal surface of the slider is fixedly provided with a hydraulic rod mechanism on the side away from the base, the end of the hydraulic rod mechanism is fixedly connected with the middle part of one end of the slider, the slider moves horizontally on the base under the action of the hydraulic rod mechanism, the upper end of the slider is vertically fixedly provided with a stop block on the side close to the base, the stop block moves together with the slider until the side wall of the cradle support is in contact with the stop block, the position of the cradle support is limited, the upper end of the stop block is horizontally fixedly provided with a supporting plate on the side away from the positioning frame, the supporting plate supports the dial indicator, the position of the dial indicator is stable, the dial indicator is used for reading the size of the measured size, when the angle of the cradle support is measured, the upper end of the end cover is horizontally provided with the cradle support, the lower end of the positioning block is in contact with the cutout at the two ends of the cradle support, the V-shaped groove of the rocker support is upwardly provided with a cylindrical pin, one end of the dial indicator is in contact with the cylindrical pin, the position of the cylindrical pin in the V-shaped groove is moved first, then the position of the dial indicator is moved, and each part of the V-shaped groove is measured.

[0006] Preferably, the inclination angle of the lower end of the positioning block is 15°, and the included angle between the cutout and the horizontal plane is the same when the V-shaped groove of the rocker support is vertically upward.

[0007] Preferably, the length of the stop block is less than the distance between the positioning frames, so that the stop block can be moved to be in contact with the side wall of the cradle support.

[0008] The utility model discloses the beneficial effect is: one side of cradle support is in contact with positioning frame, the other side of cradle support is in contact with stop block, the lower end of positioning block is in contact with the cutout at the two ends of cradle support, and the position of the upper part of the two ends of cradle support is limited, the end cover moves upward under the action of spring elasticity, and the lower end of cradle support is in contact with the end cover, the position of cradle support is stable and reliable, the position of cradle support is avoided to deflect, the position of the cylindrical pin in the V-shaped groove is moved first, then the position of dial indicator is moved, each part of V-shaped groove is measured, and the accuracy of measurement result is guaranteed, so that unqualified cradle support can be avoided to flow to downstream equipment manufacturer, and the market competitiveness and quality reliability of enterprise are improved.
