Abstract
The utility model belongs to a clamp, and particularly relates to a floating type hole grinding clamp. The floating type hole grinding clamp is characterized by comprising a base plate, support pillars, a ring-shaped plate, a press plate, a support screw and pin shafts. The support pillars are vertically connected with the base plate through bolts to form a manger-shaped whole. The ring-shaped plate is in pin connection with the bilateral support pillars through the pin shafts. A round plate of an installation clamp workpiece is arranged on a ring center of the ring-shaped plate, and adjusting support screws are in threaded connection with the base plate. The round plate is arranged above end faces of the adjusting support screws, and a movable gap is arranged between the round plate and the end faces of the adjusting support screws. The floating type hole grinding clamp has the advantages that rapid loading and unloading can be achieved through a compaction inclined face of the press plate, the ring-shaped plate and the round plate can freely move, so that the aim of 360-degree free floating is achieved. A grinding hole is machined in floating type grinding, so that geometric accuracy of a machining hole is guaranteed.
Description
Technical field
The utility model belongs to anchor clamps, relates in particular to a kind of floating type porting anchor clamps that are used in conjunction with porting equipment.
Background technology
The attrition process of conventional pilot hole to some sewing machine components (such as sewing machine oil pump) all is to adopt the drilling machine grinding rod that is installed, and the operative employee holds workpiece and carries out " floating type " porting.Need during the higher hole of grinding precision grind at bench drill manually, the method can guarantee that the hole grinding is qualified. but all higher for operator's technical ability and physical fitness requirement, simultaneously the operator because the lapping liquids such as hand contact kerosene can cause irritated grade for malaise symptoms, and grinding efficiency is very low and quality is unstable manually in long-term process of lapping.Labor strength is very large, and operating efficiency is low, and is prone to accidents.Factory develops a kind of porting anchor clamps, when being installed the porting workpiece, need to frequently turn hold-down bolt, and efficiency improves and be not obvious, and operative employee's labour intensity is also without reducing.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of floating type porting anchor clamps to be provided, make by the porting workpiece and can realize 360 ° of free floatings, and workpiece loading and unloading being convenient, fast.
The utility model to achieve these goals, be achieved through the following technical solutions, a kind of floating type porting anchor clamps, it is characterized in that: comprise base plate, pillar, annular slab, pressing plate, studdle and bearing pin, described pillar is by screw connect into manger shape integral body vertical with base plate, described annular slab is by the pillar pin joint of bearing pin and both sides, the circle ring center of described annular slab is equipped with the plectane of card engaging workpiece, be bolted with the adjustment studdle on the described base plate, the plectane of described card engaging workpiece places adjusts studdle end face top.
The plectane of described card engaging workpiece is by the annulus pin joint of housing screw and annular slab.
The plectane upper surface of described card engaging workpiece is provided with by the connected pressing plate of screw.
Described pressing plate and workpiece connecting surface are provided with the compression inclined-plane.
Be provided with the free gap between the plectane of described card engaging workpiece and the adjustment studdle end face.
The plectane center of described card engaging workpiece is provided with the frock hole, and described base plate center is provided with the technique via hole.
Described adjustment studdle quantity is four, and the position that is square is screwed onto on the base plate.
Beneficial effect: be the special tooling jig of batch production sewing machine oil pump design.Can realize the quick loading and unloading of workpiece by the compression inclined-plane of pressing plate.Annular slab and plectane all can be freely movable, thereby realize the purpose of design of 360 ° of free floatings, and porting is floating type attrition process, to guarantee the geometric accuracy of machining hole.Greatly improve labor productivity, significantly alleviated operative employee's labour intensity.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the top view of Fig. 1.
Among the figure: 1, bearing pin, 2, pressing plate, 2-1, compress the inclined-plane, 3, housing screw, 4, base plate, 5, pillar, 6, annular slab, 7, the plectane of card engaging workpiece, 8, adjust studdle, 9, screw, 10, screw, 11, workpiece, 12, the frock hole, 13, the technique via hole.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides: see accompanying drawing for details, a kind of floating type porting anchor clamps, comprise base plate 4, pillar 5, annular slab 6, pressing plate, studdle and bearing pin, described pillar is by screw 9 connect into manger shape integral body vertical with base plate, described annular slab is by the pillar pin joint of bearing pin 1 with both sides, the circle ring center of described annular slab is equipped with the plectane 7 of card engaging workpiece, be bolted with on the described base plate and adjust studdle 8, described adjustment studdle quantity is four, and the position that is square is screwed onto on the base plate.Described plectane places adjusts studdle end face top, is provided with the free gap between the plectane of described card engaging workpiece and the adjustment studdle end face.The plectane of described card engaging workpiece is by the annulus pin joint of housing screw 3 with annular slab.The plectane upper surface of described card engaging workpiece is provided with by screw 10 connected pressing plates 2.Described pressing plate and workpiece connecting surface are provided with and compress inclined-plane 2-1, and the workpiece loading and unloading frock hole rotation of only need packing into get final product to the inclined-plane during porting, also only needs reverse rotation can take out workpiece when unloading workpiece, the work of having saved stubborn bolt compression fully and having unclamped.The plectane center of described card engaging workpiece is provided with frock hole 12, and described base plate center is provided with technique via hole 13.
The course of work:
Floating type porting anchor clamps take full advantage of rotation friction and the inclined-plane self-lock mechanism of porting.Floating type porting anchor clamps and superfinishing hole abrading machine support the use (also can generally be used for other bench drill, grinder etc.).Rotate to the inclined-plane pressing plate in the hole with workpiece to be ground 11 oil pump body shanks insertion plectane during use, grinding rod carries out grinding work, and the reverse rotation workpiece took out workpiece and finishes attrition process after attrition process finished from the hole of plectane.Above several hang-ups have been captured in the successful development of the porting frock of should floating at one stroke, and the operator only needs to get final product toward the frock lifting workpiece, greatly reduce the requirement to operator's technical ability and muscle power, have also greatly shortened the time that the operator contacts with lapping liquid simultaneously.Because this frock can 360 ° of free floatings, the holes of products roundness tolerance after therefore grinding and linearity tolerance be all less than 0.002 μ m, and grinding efficiency and dimensional stability are ground lifting more than one times more manually.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment all still belong in the scope of drawing the art scheme of the present utility model.
