Description
Technical Field
The invention belongs to the technical field of rough machining, relates to a clamp, and particularly relates to a hydraulic synchronous clamp for drilling an automobile hub bearing flange.
Background
The drilling processing is a common processing means in an existing production and processing workshop, the drilling processing is generally realized through the matching of a drill bit and a clamp, the clamp clamps a workpiece, then the drill bit is in rigid contact with the workpiece under the driving of an oil cylinder, and the drill bit is pressed downwards and can rotate to drill a hole position on the workpiece.
The drilling of workpieces such as automobile wheel hub flanges and the like is carried out by clamping the three-jaw chuck. In the drilling process, the position of a hole to be drilled is likely to be deviated, the coaxiality is not high when the flange is clamped, the flange is likely to be deviated on one side when the flange is in rigid contact with a drill bit, particularly, flanges of large parts such as hub flanges of heavy trucks are not good in clamping, the used drill bit is large in rigid contact force and large in rigid contact force, and the position where the drill bit is contacted with a workpiece is easy to sink when the hole position is drilled. Therefore, a flange to be machined needs to be fixed to enable the flange to be machined not to deviate and vibrate in the machining process, large flange plates are large in size, impact force is huge in the drilling process, a specific frame is welded generally, then the frame is directly fixed with clamping jaws of a three-jaw chuck through bolts, and therefore the flange and a clamp form an integrated structure, machining is convenient, and precision is high. But the disassembly and the clamping are time-consuming and labor-consuming, so that the integral production and processing efficiency cannot be improved.
Disclosure of Invention
The invention aims to provide a hydraulic synchronous clamp for drilling an automobile hub bearing flange, aiming at the problems in the prior art. It solves the technical problem that the prior hub flange is inconvenient to fix when drilling.
The purpose of the invention can be realized by the following technical scheme:
the utility model provides an automobile wheel hub bearing flange is hydraulic pressure synchronous clamp for drilling, includes the base, be equipped with the constant head tank that can supply panel card to go into on the base, the both sides that lie in the constant head tank on the base all articulate there is clamp splice and two mutual symmetries of clamp splice, its characterized in that, the below that lies in the constant head tank on the base is equipped with can reciprocal pivoted rotor block and rotor block pivoted central line the same with clamp splice pivoted central line, is connected with connecting rod one and connecting rod two between two clamp splices and the rotor block respectively, and two clamp splices can rotate towards opposite direction under the drive of connecting rod one and connecting rod two respectively when the rotor block rotates.
This anchor clamps are through seting up the constant head tank on the base, the flange can be directly go into in the constant head tank through hoist and mount card, the lateral part of flange receives the spacing unable removal of the both sides cell wall of constant head tank, the both sides bottom of flange can directly support and obtain supporting in the tank bottom of constant head tank, can effectually prevent to remove at the in-process of drilling, if meet the width that the flange width is less than the constant head tank we also can let the flange side direction can not take place the off normal through the thing of establishing the billet or other can support between the cell wall of constant head tank and flange side, the design can effectively make the flange add the level and the vertical direction can not take place to remove with man-hour, moreover, the steam generator is simple in structure, and is very convenient.
All articulated in the both sides of constant head tank have the clamp splice, and the clamp splice can rotate, can support after rotating and press on the flange in the constant head tank, and the flange lower extreme supports to receive the clamp splice to support to press and let the flange receive spacing can not its perpendicular and horizontal direction can not take place the skew when contacting with the drill bit rigidity at the vertical direction under the flange, fixes the flange that can be fine.
The rotation of the two clamping blocks is controlled through the rotating block, the first connecting rod and the second connecting rod are connected between the two clamping blocks and the rotating block respectively, and the rotating block can pull the first connecting rod and the second connecting rod to move oppositely so as to drive the two clamping blocks to rotate towards opposite directions, so that the two clamping blocks can be controlled to clamp or loosen the flange, and the flange is very convenient to fix.
