The technical solution for realizing the utility model aim is a kind of positioning fixture for the drilling of engine cylinder hd top face, packet Pedestal is included, workbench on the base is set, is provided with rectangular positioning seat on the workbench, in the positioning seat It is inside provided with the positioning round orifice of top surface opening, setting circle is provided in the positioning round orifice to column, supports column in the setting circle Bottom surface and the positioning round orifice bottom wall between be fixed with and compress spring, be provided with side in four sides of the positioning seat The clamping cylindrical cavity of face opening, is fixed with gripper cylinder in the clamping cylindrical cavity, fixed on the piston shaft of the gripper cylinder There is C clamp briquetting, the bottom end of the C clamp briquetting is fixed on the top surface that on the piston shaft of gripper cylinder and top is in positioning seat Top, the C clamp briquetting top under the action of gripper cylinder clamp on the side of workpiece.
It is provided with translational adjustment slot on the base, is fixed with translational adjustment sliding block, institute in the bottom surface of the workbench It states translational adjustment sliding block to be in the translational adjustment slot, drive lead screw, the translation is provided in the translational adjustment slot Adjusting slider is threaded on the drive lead screw, is fixed on the outside of the pedestal and is connected with the drive lead screw Manually adjust turntable.
Anti-skid fine lines slot is evenly arranged on the cramping face of the C clamp briquetting.
The control button for being fixed with external gas source port on the positioning seat and being connected with gripper cylinder.
The utility model has the effect of positive: the structure setting of the utility model is reasonable, is provided with setting circle and supports column, It can be pressed on the bottom surface of workpiece, to prevent workpiece from the case where deviation occur, while C clamp briquetting is being additionally provided with, is clamping It can clamp under the action of cylinder in the side of workpiece, so that workpiece positioning be made to fix, be conducive to the stabilization for improving clip position Property and reliability, be conducive to the precision for improving drilling processing, stability in use is good and strong applicability.
Detailed description of the invention
In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached Figure, is described in further detail the utility model, in which:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the utility model, and wherein Fig. 1 is the structural representation of the utility model Figure.
See Fig. 1, a kind of positioning fixture for the drilling of engine cylinder hd top face, including pedestal 1, is arranged in the pedestal 1 On workbench 2, rectangular positioning seat 3 is provided on the workbench 2, be provided in the positioning seat 3 top surface opening Positioning round orifice 4, setting circle is provided in the positioning round orifice 4 to column 5, the setting circle support the bottom surface of column with it is described fixed It is fixed between the bottom wall in circle of position hole and compresses spring 6, be provided with the clamping of side opening in four sides of the positioning seat 3 Cylindrical cavity 7 is fixed with gripper cylinder 8 in the clamping cylindrical cavity, C clamp briquetting is fixed on the piston shaft of the gripper cylinder 9, the bottom end of the C clamp briquetting is fixed on the top face that on the piston shaft of gripper cylinder and top is in positioning seat, the C Clevis briquetting top under the action of the gripper cylinder clamps on the side of workpiece.In the present embodiment, gripper cylinder is existing There is the structure of technology, therefore does not record in detail.
It is provided with translational adjustment slot 10 on the base, is fixed with translational adjustment sliding block in the bottom surface of the workbench 11, the translational adjustment sliding block is in the translational adjustment slot, and drive lead screw 12, institute are provided in the translational adjustment slot It states translational adjustment sliding block to be threaded on the drive lead screw, be fixed on the outside of the pedestal and the drive lead screw phase Connection manually adjusts turntable 13.
