Detailed Description
As shown in fig. 3, 4, 5, 6 and 7, the lateral pressure drilling fixture for the lower through beam comprises a bottom plate 4, wherein a positioning part 5 and a clamping mechanism 6 are arranged on the bottom plate, the positioning part is used for axially positioning a workpiece, and the clamping mechanism is used for clamping the workpiece and positioning a drilled hole; the clamping mechanism 6 is composed of a left clamping mechanism 61 and a right clamping mechanism 62 which have the same structure, and the structure of the left clamping mechanism 61 is as follows: the device comprises a wrapping fixing plate 611, a fixed pressing block 612, a movable pressing block 613, a driving cylinder 614 and a drilling template 615, wherein the fixing plate is fixed on a bottom plate, the fixed pressing block is fixed on the fixing plate, the movable pressing block moves opposite to the fixed pressing block through the driving cylinder, the drilling template is fixed on the fixed pressing block, and the drilling template and a workpiece are arranged vertically and oppositely;
as shown in fig. 6 and 7, the back surface of the bottom plate 4 is symmetrically provided with reinforcing ribs 41, so as to improve the service life and facilitate light weight;
as shown in fig. 3 and 6, the positioning member 5 has a structure: the positioning device comprises a positioning seat 51 and a positioning pin 52, wherein the positioning seat is fixed on a bottom plate, the positioning pin is fixed on the positioning seat, the diameter of the positioning pin is smaller than the aperture of a workpiece, and the positioning pin can be inserted into a hole cavity of the workpiece; the advantages are that: the positioning seat is matched with the positioning pin, so that five degrees of freedom of the workpiece are limited, and the workpiece is ensured to be accurately positioned; the structure is suitable for workpieces of various models, improves the universality and is beneficial to reducing the cost;
as shown in fig. 6 and 7, the pressing surfaces of the fixed pressing block 612 and the movable pressing block 613 are concave V-shaped, and the V-shaped grooves are suitable for various types of workpieces, so that the universality is improved, and the cost is reduced;
as shown in fig. 6 and 7, an insert sleeve 616 is arranged in the drilling positioning hole on the drill plate 615, the insert sleeve is made of 40Cr steel and is quenched with HRC58-62, and the overall rigidity and wear resistance are ensured.
As shown in fig. 3, 6 and 7, the bottom plate 4 is provided with an error-proofing positioning component 7, which is composed of an angle positioning block 71 and an error-proofing positioning block 72, the angle positioning block is fixed on the bottom plate, the error-proofing positioning block is fixed on the inclined plane of the angle positioning block, a positioning groove is formed by the supporting surface of the error-proofing positioning block and the inclined plane of the angle positioning block, and the positioning groove is used for positioning and clamping the deflection angle of the workpiece to prevent errors; the angle positioning block ensures the deflection angle between the drilling direction and the axis of the lower through beam, and the error-proof positioning block can prevent the left and right directions from being reversely placed because the center line of the arc part of the lower through beam is not coaxial with the midpoint line of the length, namely the lengths from the center of the arc to the two ends of the workpiece are not consistent.
The utility model discloses well each part adopts bolt or locating pin rigid connection and location, and relative position is fixed. Positioning pin holes are reserved in a fixing plate and a bottom plate in the left clamping mechanism and the right clamping mechanism, and the fixing plate is moved left and right to be fixed to corresponding positions when lower through beams with different lengths and hole center distances are machined. The movable pressing block is rigidly connected with the cylinder shaft through a connecting sleeve, the cylinder pushes the movable pressing block to move towards the fixed pressing block, and when the workpiece is pressed, the workpiece is limited to move left and right and rotate.
The clamping step of the clamp comprises: 1) Cleaning the clamp: the clamp is clean and clean without impurities; 2) And the lower through beam is hoisted to the clamp, the right end of the workpiece is shorter than the left end, the short end part of the workpiece is abutted against the positioning seat, the positioning seat realizes axial positioning on the workpiece, the arc part of the workpiece is abutted against the angle positioning block, and whether the two ends of the workpiece are misplaced or not can be judged by whether the supporting surface of the angle positioning block is abutted against the inner arc surface of the workpiece or not. Because the right-hand member of work piece is shorter than the left end, after the left end of work piece and positioning seat location cooperation, the intrados of work piece can't laminate with the holding surface of angle locating piece, consequently, the both ends of work piece need the switching-over. And finally, starting the driving cylinder, and enabling the fixed pressing block and the movable pressing block to be matched for clamping the end part of the workpiece, wherein a drill bit of the drilling machine penetrates through the insert sleeve to drill holes, as shown in fig. 8.
