Description
Technical Field
The utility model belongs to the technical field of the auto-parts apparatus, especially, relate to a quick fixture mechanism for leaf spring eye.
Background
Leaf springs are common fittings in automobiles. When the eye at the two ends of the leaf spring is processed, a boring process is added for ensuring the roundness of the eye of the leaf spring. The boring process greatly prolongs the service life of the lining inside the leaf spring eye. The current boring technology is to clamp the leaf spring eye by a three-jaw chuck at the beginning of processing, and then bore the eye. However, due to the problems of lateral bending and lug deformation of the plate spring, the axial line of the lug is not perpendicular to the central line of the middle of the lug, so that the installation of the bushing after final boring is difficult, and the problems of breakage and the like are easily caused due to uneven stress in use.

An object of the utility model is to solve above the technical problem, the straightness that hangs down of the ear hole that a boring came out and middle reference surface is very good is provided for the leaf spring atress is even, has promoted the leaf spring ear of the yields of leaf spring installation and life greatly and has used quick fixture mechanism, its technical scheme as follows:
the quick clamp mechanism for the leaf spring eye comprises a base and is characterized in that two ends of the base are provided with eye fixing mechanisms in a sliding manner, and the two eye fixing mechanisms are symmetrically arranged; the ear rolling fixing mechanism comprises a sliding seat arranged on a base in a sliding mode, the sliding seat comprises a horizontal plate and a vertical plate, an adjusting plate is hinged to the upper portion of the vertical plate, one side of the bottom of the adjusting plate is hinged to the vertical plate, a threaded rod is arranged on one side of the adjusting plate, the threaded rod penetrates through the vertical plate and then is fixed to one side of the adjusting plate, and the threaded rod is rotated to adjust the angle between the adjusting plate and the vertical plate; an air cylinder is arranged on the adjusting plate, and the output end of the air cylinder is connected with an ejector rod; the middle of the two lug rolling fixing mechanisms is provided with a baffle and a lateral cylinder, the output end of the lateral cylinder is connected with a movable plate, and the movable plate is driven by the lateral cylinder to be close to the baffle.
The sliding seats have the functions that the distance between the two sliding seats can be adjusted according to different types of plate springs, and a plate spring clamping platform can be provided; the plate spring has the advantages that the plate spring can adapt to plate springs of more types, and the effect of one machine with multiple purposes is achieved; and secondly, a reference is provided, and the vertical accuracy of the axis of the eye curl and the middle center line is improved. The effect of regulating plate and threaded rod is the angle between regulating plate and the vertical plate, and its effect can adjust the position of ejector pin for the ejector pin can adjust the contact position with the book ear outside portion according to different model leaf springs, thereby improves the oppression, prevents that the book ear from taking place the displacement in the bore hole, improves the perpendicular precision of book ear axis and middle central line. The baffle and the movable plate are used for fixing the middle part of the plate spring, so that the rolling ears at two ends of the plate spring are prevented from displacing in boring, and the vertical accuracy of the axis of the rolling ears and the middle center line is ensured. The two lug rolling fixing mechanisms are symmetrically arranged, so that the stress consistency of two sides of the plate spring can be ensured when the lugs are bored, and the plate spring is prevented from rotating and displacing when the lugs are bored; secondly, a quick-witted two stations can once only bore a hole 2, and a leaf spring is once only processed and is accomplished, raises the efficiency, has also guaranteed the uniformity of 2 book ear holes simultaneously, has promoted the yields and the life of leaf spring installation greatly.
Preferably, the sliding seat is provided with an L-shaped protection plate attached to the sliding seat.
The function of the L-shaped protection plate is to provide protection for the plate spring. The eye at leaf spring both ends is when the bore hole, and the bottom and the lateral part of leaf spring can receive the effort oppression, and L-shaped guard plate can play the guard action.
Preferably, the edge of the L-shaped protection plate is provided with a convex edge.
The convex edge plays a role of blocking. When the eye at the both ends of the plate spring is bored, the main anti-displacement device is the clamp of the baffle and the moving plate which are positioned at the middle part. In operation, sometimes two sides are asymmetric due to the problem of placement, and the leaf spring has small rotary displacement when the eye is bored. The convex edge can well prevent the rotary displacement, so that the vertical accuracy of the axis of the lug and the middle center line is ensured.
The utility model has the advantages that: the perpendicularity of the bored eye and the middle reference surface is very good, so that the stress of the plate spring is uniform, and the yield and the service life of the plate spring are greatly improved.

Detailed Description
The following embodiments are specifically described with reference to fig. 1 to 2:
as shown in fig. 1 and 2, a metal base 1, which may also be a metal work platform, must ensure flatness. The base is provided with a slide way, a lug rolling fixing mechanism 2 is arranged above the slide way, the lug rolling fixing mechanism comprises a slide seat 3, and the slide seat is generally L-shaped. The sliding seats can slide on the sliding ways, so that the distance between the two sliding seats can be adjusted. The L-shaped carriage generally comprises a horizontal plate 4 and a vertical plate 5.
The L-shaped protective plate 6 is welded on the L-shaped sliding seat, and the L-shaped protective plate is used for supporting the end part of the rolling lug when the rolling lug is placed, so that the L-shaped protective plate is fixed and has a protective effect. Generally, a material having a slight elasticity is used.
A flange 7 is welded to the edge at the lower part of the L-shaped slide. The convex edge enables the force generated by the hole machining tool to be well offset in the hole machining process, and the whole lug can not be displaced.
The L-shaped slide includes a horizontal plate and a vertical plate. An internal thread hole is formed in the upper portion of the vertical plate, and a threaded rod 8 is installed in the internal thread hole. One end of the threaded rod passes through the internal threaded hole and then is connected with the left side of the adjusting plate 9. And the adjusting plate is hinged on the vertical plate. The side of the adjusting plate hinged with the vertical plate is the side connected with the threaded rod. The position of the adjusting plate hinged with the vertical plate is positioned at the lower part of the left side of the adjusting plate, and the connecting position of the threaded rod and the adjusting plate is positioned at the upper part of the left side of the adjusting plate. Therefore, the threaded rod is rotated, the threaded rod is enabled to be pressed against the upper portion of the left side of the adjusting plate through the internal threaded hole, and the whole adjusting plate is enabled to incline downwards through the hinged portion. The right side of the adjusting plate is provided with an air cylinder 10, the output end of the air cylinder is connected with an ejector rod 11, and when the adjusting plate is inclined downwards to a certain angle. The cylinder drives the ejector rod to eject, and the ejector rod props against the arc part of the rolling lug. Thereby playing the role of fixing the ear-curler.
The utility model discloses a be two book ears fixed establishment to can fix the book ear of leaf spring both ends department. One function is that the balance is better when processing, and the position of the rolling lug can not be deviated; the other function is to process 2 eye curls at the same time, accelerates the efficiency and also makes 2 eye curls hole keep the uniformity simultaneously.
