Flexible auxiliary support

Abstract

A flexible auxiliary supporting device is composed of an elastic pin, a body, a steel ball, a rotary knob, a spring, a nut and a limiting screw and is characterized in that when a workpiece is not placed and the rotary knob is in a screwing-out state, a gap is formed between a plane on the steel ball and an inclined plane on the elastic pin, and the elastic pin is in a free floating state under the action of the spring; under the action of the gravity of a workpiece, the elastic pin overcomes the elastic force of the spring to descend, the knob is manually screwed, and the steel ball which is embedded in the head of the knob and provided with the plane tightly abuts against the inclined plane of the elastic pin, so that the elastic pin stops at the descending position and can bear downward pressure, and the steel ball embedded in the head of the knob is provided with the plane and can freely rotate; therefore, when the knob is rotated to enable the plane of the steel ball to abut against the inclined plane of the elastic pin, the elastic pin cannot move up and down, strong supporting of the elastic pin to the workpiece at the stop position can be achieved, and even if the size of the position, needing to be supported, of the workpiece is changed, high-flexibility self-adaptive tight connection supporting can be achieved.

Description

Technical Field

[0001] The utility model design relates to a flexible auxiliary supporter which plays a supporting role in the field of mechanical processing and automated manufacturing. Background Art

[0002] At present, it is well known that bolt-type supports can play a supporting role for workpieces. The usual practice is to manually adjust the bolt-type supports so that the supports can firmly and reliably support the corresponding parts of the workpieces. However, when the size of the parts to be supported in a batch of workpieces varies, the bolt-type supports need to be used according to the height of each workpiece. The height of the bolt-type supports needs to be adjusted separately, which will inevitably take a long time and will inevitably cause the production line to stop for a long time, thereby wasting a lot of downtime and greatly reducing the production utilization rate of production equipment. Summary of the invention

[0003] In the process of clamping and supporting a workpiece on a production line, in order to reduce the time of line stoppage and to achieve fast, firm and reliable support of the workpiece, the utility model provides a flexible auxiliary supporter. This flexible auxiliary support is installed on the workbench through the external thread and nut on the main body. When no workpiece is placed, the knob is in an unscrewed state, and there is a gap between the plane on the steel ball and the inclined surface on the spring pin. The spring pin is in a free floating state under the action of the spring. At this time, the workpiece to be supported is placed on the spring pin, and the workpiece contacts the spring pin. Under the action of the gravity of the workpiece, the spring pin overcomes the spring force of the spring and descends. At this time, the knob is manually rotated, and the steel ball with a flat surface that can roll freely and is embedded in the head of the knob is pressed against the inclined surface of the spring pin, so that the spring pin stops at the descending position and can withstand the downward pressure. Because the steel ball embedded in the head of the knob has a flat surface and can rotate freely, when the knob is rotated to make the steel ball flat surface press against the inclined surface on the support column, the spring pin will not be likely to move up and down, and the spring pin can effectively support the workpiece in the stopped position. Even if the size of the workpiece to be supported changes, highly flexible and adaptive close support can be achieved.

[0004] The design scheme adopted by the utility model to realize the flexible and adaptive close-fitting support function is: it is composed of a spring pin, a body, a steel ball, a knob, a spring, a nut, and a limit screw, and is characterized in that the steel ball is embedded in the knob head, the plane on the steel ball faces outward, the steel ball can rotate freely, the groove mouth of the knob head where the steel ball is embedded has an undercut so that the steel ball with the plane cannot fall out, the knob is installed in the inclined threaded hole of the side wall of the body through its own external thread, the spring pin is installed in the hole of the body, the limit screw is installed in the screw hole of the side wall of the body, the head of the limit screw is located in the limit groove on the side of the spring pin, the spring is installed in the body, the lower end face of the spring is pressed against the bottom of the hole in the body, the upper end face of the spring is pressed against the bottom of the spring pin, the nut is installed on the external thread at the lower part of the body through its internal thread, and the side walls of the spring pin are respectively provided with inclined surfaces for pressing and limit grooves for limiting.

[0005] The utility model has the beneficial effect that it is composed of a spring pin, a body, a steel ball, a knob, a spring, a nut and a limit screw, and is characterized in that when no workpiece is placed and the knob is in a screwed-out state, there is a gap between the plane on the steel ball and the inclined surface on the spring pin, and the spring pin is in a free floating state under the action of the spring. At this time, the workpiece is placed on the spring pin, the workpiece contacts the spring pin, and under the action of the gravity of the workpiece, the spring pin overcomes the elastic force of the spring and falls. At this time, the knob is manually tightened, and the steel ball with a plane that can roll freely and is embedded in the knob head is pressed against the inclined surface of the spring pin, so that The spring pin stops at the position when it is descending and can withstand the downward pressure. Because the steel ball embedded in the knob head has a flat surface and can rotate freely, when the knob is rotated to make the steel ball flat surface press against the inclined surface on the spring pin, the spring pin will not be able to move up and down, and the spring pin can effectively support the workpiece at the stopped position. Even if the size of the workpiece to be supported changes, highly flexible and adaptive strong close support can be achieved. After the support is installed on the tooling plate through the external thread on the lower part of the main body, the support can be tightened to the tooling plate with a nut.
