Preset self-adjusting full-positioning clamping device for automobile part drilling

Abstract

The invention relates to a preset self-adjusting full-positioning clamping device for automobile part drilling, which comprises a rack, a drilling auxiliary clamping device, a human-hand-simulated self-resetting reciprocating type cleaning mechanism and a detachable self-separation recovery device, a dust collection hole is formed in the middle of the upper wall of the rack, the human-hand-simulated self-resetting reciprocating type cleaning mechanism is arranged on the upper wall of the rack, and the detachable self-separation recovery device is arranged on the lower wall of the rack. The drilling auxiliary clamping devices are symmetrically arranged on the machine frame, and the detachable self-separation recycling device is arranged under the dust collecting holes. The invention belongs to the technical field of clamping devices for drilling parts, and particularly provides a clamping device for drilling parts by utilizing a dynamic characteristic principle, a principle of changing harm into benefit and a pre-reaction principle and by virtue of a magnetic field as compensation. According to the preset self-adjusting full-positioning clamping device for drilling the automobile parts, all-directional dead-corner-free self-adaptive attaching type clamping can be carried out on various types of automobile parts with uneven clamping faces under the condition that no positioning element or other sensors exist, the efficiency is high, and the automation degree is high.

Description

technical field [0001] The invention belongs to the technical field of clamping devices for parts drilling, and in particular relates to a clamping device for drilling auto parts with preset self-adjustment and full positioning. Background technique [0002] When drilling auto parts, on the one hand, due to the large stress generated by drilling, in order to ensure that the parts do not loosen during drilling, it is necessary to apply a sufficient clamping force to the parts; on the other hand , Because the clamping surface of some auto parts is not flat, the contact area between the fixture and the parts is small, and it is often based on point contact or line contact, and it is easy to concentrate pressure on the parts. If the applied clamping force is too large, the pressure at the clamped part of the component will be too large, deformation and density changes will easily occur, and the clamp will also be damaged due to excessive pressure. In order to ensure the stabili...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a kind of preset self-adjusting full positioning auto parts drilling clamping device, which creatively uses the principle of dynamic characteristics (automatically adjusting the object, so that it can be adjusted in each action, The performance of the best stage), the principle of turning harm into benefit (using harmful factors to obtain beneficial results) and the principle of pre-reaction (applying reaction in advance to eliminate adverse effects) are applied to the technical field of clamping devices, and at the same time With the help of magnetic field as compensation, according to the unevenness of the clamping surface of different auto parts, a full-coverage magnetic compensation type self-adjusting lateral clamping mechanism is proposed, which turns harm into benefit, and decomposes the conventional integrated clamping components into multiple parts. The group can cooperate with each other as a whole, and at the same time, it can be adjusted independently in a rectangular array. The dynamic adjustment type magnetic compensation type adaptive clamping component can perform all-round self-adaptive sticking on various types of auto parts with uneven clamping surfaces. Fitted clamping greatly increases the contact area between the clamping component and th
