Abstract
The utility model relates to a pneumatic clamp used for processing a bearing front cover of a horizontal lathe. The pneumatic clamp mainly solves the problem in the traditional mechanical processing of the bearing front cover that defects in the clamping manner results in long clamping time, small clamping force and form-position out-of-tolerance. The pneumatic clamp is characterized in that the left end of a clamp body (8) is connected with a positioning seat (11), the left end of the positioning seat (11) is connected with a positioning ring (12) matched with the inner hole of the front cover, a pull rod (9) is connected with a pressure plate (6), a holding jaw (1) is fixed at two ends of the pressure plate (6), the end part of the holding jaw (1) is in the shape of a hook, and the end surface of the hook cooperates with an inclined surface on the outer side of the front cover. Compared with the traditional clamp which adopts the radial clamping mode, the pneumatic clamp adopts the axial clamping mode, thereby improving processing precision, processing efficiency and safety factor and reducing labor intensity.
Description
Technical field
The utility model relates to a kind of mechanical field, the used air operated fixture of a kind of specifically horizontal lathe machining bearing protecgulum.
Background technology
Bearing in the railway freight-car is rolling bearing, and the effect of its middle (center) bearing protecgulum is and the common fastening bearing inner race of back shelves, makes it to be in operation, at the unlikely generation play of the effect lower bearing of axial force.At present main CA6140 type lathe and the 250 model chuck of adopting of the machining of bearing protecgulum part made soft pawl processing by oneself, and this installation way mainly contains three shortcomings: the one, and soft pawl cooperates with the chuck parcel and does not with great difficulty cause the form and position tolerance of product overproof; The 2nd, operator's labour intensity is big, and the clamping time is long; The 3rd, clamping folder power is less, and claw wearing and tearing back is prone to produce potential safety hazard.
Summary of the invention
When overcoming existing bearing protecgulum machining owing to the defective of installation way make the clamping time long, clamping power is little, cause the overproof deficiency of form and position tolerance; The utility model provides a kind of horizontal lathe machining bearing protecgulum used air operated fixture; The mode that this air operated fixture radially clamps original anchor clamps changes axial clamping into, has improved machining accuracy, improves working (machining) efficiency, has reduced labour intensity, has improved safety coefficient.
The technical scheme of the utility model is: the used air operated fixture of a kind of horizontal lathe machining bearing protecgulum; Comprise clamp body, the pull bar that links to each other with cylinder, described clamp body left end is connected with positioning seat, and the positioning seat left end is connected with the centring ring that matches with the protecgulum endoporus; Described pull bar is connected with pressing plate; And the two ends of pressing plate are fixed with jaw, and it is hook-shaped that described jaw end becomes, and the end face that colludes matches with inclined-plane, the protecgulum outside.
Described positioning seat be externally connected to the balance seat, described jaw passes the balance seat, and the balance seat is provided with the guider screw perpendicular to the jaw axis.
Be provided with adjusting pad and spheric washer with the pressing plate junction on the described jaw.
The utlity model has following beneficial effect: owing to take such scheme, pull bar links to each other with cylinder, and cylinder action pulling pull bar just can drive the pressing plate action, thereby drive the jaw axially-movable protecgulum is clamped.These anchor clamps change the radially clamping mode of original anchor clamps into axial clamping; Optimized the workpiece stressing conditions; Improve clamping speed, alleviated operator's labour intensity, also improved production efficiency simultaneously; Production efficiency has been improved about 20 %, and pneumatic pinch is compared manual clamping safety and reliability.Batch trial production through a period of time learns that these anchor clamps have improved the quality of product greatly, has fundamentally stopped 1～3 ‰ the circular runout overproof rate that is caused by original installation way.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1; The used air operated fixture of a kind of horizontal lathe machining bearing protecgulum, the pull bar 9 that comprise clamp body 8, links to each other with cylinder, described clamp body 8 right-hand members link to each other with the anchor clamps holder; Wherein the anchor clamps holder is confirmed according to the lathe spindle structure; The baffle ring 7 that establish clamp body 8 inside, baffle ring 7 can block a bar 9, plays spacing effect.Clamp body 8 left ends are connected with positioning seat 11, and positioning seat 11 left ends are connected with centring ring 12, and centring ring 12 matches with the protecgulum endoporus, and the two end face contact, make centring ring 12 can withstand protecgulum, prevent its axially play to the right.Be connected with pressing plate 6 on the described pull bar 9, the left end of pull bar 9 is connected with round nut 10, is provided with packing ring between round nut 10 and the pressing plate 6, makes pressing plate 6 axial location through packing ring, and it can together be moved axially with pull bar 9.The two ends of pressing plate 6 are fixed with jaw 1, and it is hook-shaped that jaw 1 end becomes, and the end face that colludes matches with inclined-plane, the protecgulum outside.Described positioning seat 2 be externally connected to balance seat 2, described jaw 1 passes balance seat 2, and balance seat 2 is provided with the guider screw 3 perpendicular to jaw 1 axis, the end of guider screw 3 withstands on jaw 1, the direction of jaw 1 is fixed, unlikely upset.Be provided with adjusting pad 4 and spheric washer 5 with pressing plate 6 junctions on the described jaw 1, with the size of adjustment jaw 1 clamping force.
Before the processing protecgulum, protecgulum is placed on these anchor clamps, its endoporus and centring ring 12 are matched, start cylinder, cylinder tension pull bar 9, pull bar 9 drives pressing plate 6, and pressing plate 6 drives jaw 1 and moves backward, and protecgulum is clamped on the centring ring 12.
