Abstract
The utility model relates to a clamp for gear hole drilling, comprising a gear mounting base. A cylindrical platform is arranged on the mounting base, a plurality of positioning clamping holes are distributed on the cylindrical platform in an annular array, the positioning clamping holes are wedge-shaped, and the openings of the positioning clamping holes face to the counterclockwise direction; a stepped central hole is formed on a fixing disc, and a through hole communicated with the central hole is formed on the fixing disc; a fixing nut is fixedly welded on the fixing disc and concentric with the through hole; a screw rod is in threaded connection with the fixing nut and runs through the through hole to be sleeved in the positioning sleeve; the front end of the positioning sleeve is arranged in the positioning clamping holes; and a spring is inserted onto the screw rod, and one end of the spring acts on the positioning sleeve and the other end acts on the fixing nut. As the cylindrical platform is inserted into the central hole, the working efficiency is improved, the labor intensity of workers is reduced, and the precision of gear hole drilling is improved.
Description
Technical field:
The utility model relates to the clamp technology field, more specifically to the boring anchor clamps of a kind of gear.
Background technology:
When now gear being carried out Drilling operation, that gear is installed on the anchor clamps, hole by drilling machine, when boring a plurality of holes, existing anchor clamps need to unclamp anchor clamps when machining a hole, then turn over an angle, then continue to bore next hole, this be with regard to so that gear need to carry out multiple clamping, and multiple clamping is so that workman's labour intensity is large, operating efficiency is low, and repeatedly clamping has had a strong impact on the precision of boring.
The utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and the boring anchor clamps of a kind of gear that provide, it has improved operating efficiency, has reduced workman's labour intensity, but also has improved the precision of gear boring.
Technology solution of the present utility model is as follows:
The anchor clamps that a kind of gear is boring, comprise gear installation base, form cylinder table on the mounting seat, annular array distribution has several limited bayonets on the cylinder table, limited bayonet is the chock shape, the limited bayonet opening towards being against the sun, form stair-stepping centre bore on the fixed disk, also form the perforation that connects with centre bore on the fixed disk, hold-down nut is weldingly fixed on the fixed disk and is concentric with perforation, screw rod and hold-down nut are spirally connected, screw rod pass the perforation with the positioning sleeve sleeve together, the front end of positioning sleeve places limited bayonet, the spring sleeve is on screw rod, one end active force of spring is on positioning sleeve, other end active force is on hold-down nut, and the cylinder table sleeve is in centre bore.
Form the gear inserting column on the described gear installation base, form threaded column on the gear inserting column, the pad sleeve is on threaded column, and fastening nut is screwed onto on the threaded column.
Be bolted with locking nut on the described screw rod, locking nut is pressed against with hold-down nut.
Moulding is porose on the described mounting seat, and gear installation base is bolted on the fixed disk.
The beneficial effects of the utility model are:
It only needs the clamped one time just can the porose processing in complete place, so it has improved operating efficiency, reduced workman's labour intensity, and it has also improved the precision of gear boring.

Among the figure: 1, mounting seat; 2, fixed disk; 3, gear installation base; 4, hold-down nut; 5, screw rod; 6, spring; 7, positioning sleeve; 8, locking nut; 11, cylinder table; 12, limited bayonet; 13, hole; 21, centre bore; 22, perforation; 31, gear inserting column; 32, threaded column; 33, pad; 34, fastening nut.
The specific embodiment:
Embodiment: see shown in 1 to 5, the anchor clamps that a kind of gear is boring, comprise gear installation base 3, form cylinder table 11 on the mounting seat 1, annular array distribution has several limited bayonets 12 on the cylinder table 11, limited bayonet 12 is the chock shape, limited bayonet 12 openings towards being against the sun, form stair-stepping centre bore 21 on the fixed disk 2, also form the perforation 22 that connects with centre bore 21 on the fixed disk 2, hold-down nut 4 is weldingly fixed on the fixed disk 2 and is concentric with perforation 22, and screw rod 5 is spirally connected with hold-down nut 4, and screw rod 5 passes perforation 22 and positioning sleeve 7 sleeves together, the front end of positioning sleeve 7 places limited bayonet 12, spring 6 sleeves are on screw rod 5, and an end active force of spring 6 is on positioning sleeve 7, other end active force is on hold-down nut 4, and cylinder table 11 sleeves are in centre bore 21.
Form gear inserting column 31 on the described gear installation base 3, form threaded column 32 on the gear inserting column 31, pad 33 sleeves are on threaded column 32, and fastening nut 34 is screwed onto on the threaded column 32.
Be bolted with locking nut 8 on the described screw rod 5, locking nut 8 is pressed against with hold-down nut 4.
Moulding is porose 13 on the described mounting seat 1, and gear installation base 3 is bolted on the fixed disk 2.
Operation principle: form cylinder table 11 on the mounting seat 1 of the present utility model, annular array distribution has several limited bayonets 12 on the cylinder table 11, limited bayonet 12 is the chock shape, limited bayonet 12 openings towards being against the sun, form stair-stepping centre bore 21 on the fixed disk 2, also form the perforation 22 that connects with centre bore 21 on the fixed disk 2, hold-down nut 4 is weldingly fixed on the fixed disk 2 and is concentric with perforation 22, screw rod 5 is spirally connected with hold-down nut 4, screw rod 5 pass the perforation 22 with positioning sleeve 7 sleeves together, the front end of positioning sleeve 7 places limited bayonet 12, spring 6 sleeves are on screw rod 5, one end active force of spring 6 is on positioning sleeve 7, other end active force is on hold-down nut 4, and cylinder table 11 sleeves are in centre bore 21.
Drill bit is along clockwise in boring, the novel limited bayonet 12 of this use is the chock shape, and limited bayonet 12 openings towards being against the sun, the front end of positioning sleeve 7 places limited bayonet 12, therefore lower in working order, the left side active force of limited bayonet 12 is in positioning sleeve 7, this active force has been offset the power that drill bit produces along the clockwise direction smear metal, can realize braking by above-mentioned mode, so that fixed disk 2 can not rotate, after machining a hole, only need active force in screw rod 5 so that fixed disk 2 rotates along counter clockwise direction, until positioning sleeve 7 when moving to next limited bayonet 12, just can be processed next hole.
