Description
Technical Field
The utility model belongs to the field of aviation mechanical processing technical equipment, and relates to a transverse bolt type supporting device which is a transverse auxiliary support suitable for various products during rough and fine processing.
Background
The positioning mode designed by the conventional machining clamp industry mainly comprises hole and pin matched positioning and groove and key matched positioning. An existing edge-based positioning is being developed: the edge of the product is used as a positioning reference, the product is more conveniently clamped by matching with the virtual shaft of a numerical control machine, and the problem that the product cannot be clamped when the hole, the pin and the groove and the key are matched for clamping is solved. The clamp with the side positioning needs to be matched with a matched compactor, an auxiliary support and other devices; such as various lateral compactors, lateral support pins, etc.; the fixture is used for assisting the product processing, so that the processed surface can be opened to the maximum extent, and more material removing processing can be completed by one-time clamping.
Although the lateral support nail with the matched edge being the positioning auxiliary support can meet the requirement, the adjustment is inconvenient and sometimes limited to the operation space. In order to better match with the edge system positioning of aviation products, the matched auxiliary support is required to be a transverse support device with strong universality, convenient operation and reliable support.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is: the problem that a product cannot be installed when the hole and pin are matched and the groove and key are matched for clamping is solved; in order to make the processed surface open to the maximum, a transverse supporting device with strong universality, convenient operation and reliable support is developed by matching with an edge system positioning auxiliary support.
The technical scheme of the utility model is as follows:
a transverse bolt type supporting device mainly comprises a bolt sliding shaft 2, a support 1, a supporting nail 7, a threaded handle 5 and a locking screw 6.
The support 1 is provided with a stepped hole, a large hole is in sliding fit with the bolt sliding shaft 2, and a small hole is used for auxiliary guiding of the bolt sliding shaft 2; the bottom of the support 1 is provided with a countersunk hole which is screwed on the clamp bottom plate through an inner hexagon screw 9; the upper surface of the support 1 is provided with an inclined threaded hole which is communicated with the stepped hole and used for installing a locking screw 6.
The bolt sliding shaft 2 is arranged in a stepped hole of the support 1, is of a columnar structure and comprises a large cylinder and a small cylinder; two sections all are equipped with the screw hole around the bolt slide shaft 2, and one end threaded connection screw thread handle 5, other end threaded connection supporting nail 7 to lock supporting nail 7 at the tip of bolt slide shaft 2 through lock nut 8, screw thread handle 5 and supporting nail 7 all are located outside support 1.
The large cylindrical surface of the bolt sliding shaft 2 is provided with an inclined surface, and the screwed locking screw 6 is pressed down to the inclined surface of the bolt sliding shaft 2 to prevent the support nail 7 from moving backwards caused by stress; an annular groove is arranged on the large cylindrical surface, and the position of the annular groove corresponds to the bottom of the inclined threaded hole, so that the bolt sliding shaft 2 avoids the interference of the locking screw 6 during rotation; the small cylindrical surface of the bolt sliding shaft 2 is provided with a pin hole along the radial direction, and a cylindrical pin 4 is arranged in the pin hole and used for releasing the support and adjusting the stroke. The compression spring 3 is arranged on the small cylindrical section of the bolt sliding shaft 2 and is positioned between the large cylindrical end surface of the bolt sliding shaft 2 and the small hole end surface of the support 1 and used for self-adaptive contact during supporting.
The utility model has the beneficial effects that: the transverse bolt type supporting device has strong universality, convenient operation and reliable self-locking; solves the problem that the transverse auxiliary support is matched with the edge system for positioning in order to open the field of the processing surface to the maximum extent.
