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 the uneven clamping surface, thereby avoiding the pressure concentrated on the component clamp when clamping the auto parts with uneven contact surface for drilling operations One point on the holding surface leads to the technical problem of excessive pressure at the clamped part of the part, which is prone to deformation and density change, so as to ensure that the device has a clamping effect and reduce the extrusion damage to the parts; the invention proposes The preset self-positioning reverse pressure compensation type clamping mechanism is adopted, and the vertical laser emitter and the horizontal laser emitter emit cross-positioned laser light sources of different colors to form a central color-added positioning aperture. When drilling, align the drill bit to the center and add The color positioning aperture can accurately locate the position of the drill tip, so that the drill bit can be accurately positioned during the whole process of drilling without affecting the normal drilling, ensuring that the drill bit and the drill hole are always aligned during the drilling process, which greatly improves the drilling efficiency. Hole accuracy; by pre-set self-positioning reverse pressure-compensated clamps, the auto parts are clamped in the opposite direction of the drill point position, so as to avoid the deflection of the parts in the opposite direction of the drilling position
