Abstract
The invention belongs to clamps, in particular to a float-type hole grinding clamp which is characterized by comprising a bottom plate, pillars, an annular plate, a press plate, a support screw and pin shafts, wherein the pillars are perpendicularly connected with the bottom plate through bolts to form a manger-shaped integral body; the annular plate is in pin connection with the pillars on two sides through the pin shafts; a circular plate for clamping a workpiece is arranged in the center of the circular ring of the annular plate; the adjustable support screw is in bolted connection with the bottom plate; and the circular plate is arranged above the end surface of the adjustable support screw, and is in movable clearance with the end surface of the adjustable support screw. The float-type hole grinding clamp has the benefits that the workpiece can be assembled and disassembled fast through the compressing inclined plane of the press plate; and both the annular plate and the circular plate can move freely, so as to realize the design purpose of 360-degree free floatation; and the hole is ground in a float-type manner, so as to ensure the geometric precision of the hole after processing.
Description
Technical field
The invention belongs to anchor clamps, relate in particular to a kind of floating type porting anchor clamps that are used with porting equipment.
Background technology
The attrition process of conventional pilot hole to some sewing machine components (like the 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 on bench drill, grind manually; This method can guarantee the hole grind qualified. but for operator's technical ability and physical fitness requirement all than higher; Simultaneously the operator because lapping liquids such as hand contact kerosene can cause malaise symptoms such as allergy, and grinding efficiency is very low and quality is unstable manually in long-term process of lapping.Labor strength is very big, 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 frequently turn hold-down bolt, and efficiency improves and be not obvious, and operative employee's labour intensity does not have minimizing yet.
Summary of the invention
The present invention 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 present invention to achieve these goals; Realize through following technical scheme; A kind of floating type porting anchor clamps is characterized in that: comprise base plate, pillar, annular slab, pressing plate, studdle and bearing pin, said pillar is through the vertical manger shape integral body that connects into base plate of screw; Said annular slab is through the pillar pin joint of bearing pin and both sides; The circle ring center of said annular slab is equipped with the plectane of card engaging workpiece, is bolted with the adjustment studdle on the said base plate, and the plectane of said card engaging workpiece places adjustment studdle end face top.
The plectane of said card engaging workpiece is through the annulus pin joint of housing screw and annular slab.
The plectane upper surface of said card engaging workpiece is provided with through the connected pressing plate of screw.
Said pressing plate is connected the surface and is provided with and compresses the inclined-plane with workpiece.
Be provided with the free gap between the plectane of said card engaging workpiece and the adjustment studdle end face.
The plectane center of said card engaging workpiece is provided with the frock hole, and said base plate center is provided with the technology via hole.
Said adjustment studdle quantity is four, and the position that is square is screwed onto on the base plate.
Beneficial effect: for producing the special tooling jig of sewing machine oil pump design in batches.The quick loading and unloading that workpiece can be realized in the inclined-plane that compress through pressing plate.Annular slab and plectane all can be free 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.Improve labor productivity greatly, alleviated operative employee's labour intensity significantly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical 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, the adjustment studdle, 9, screw, 10, screw, 11, workpiece, 12, the frock hole, 13, the technology via hole.
The specific embodiment
Below in conjunction with preferred embodiment; To details are as follows according to the specific embodiment provided by the invention: 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; Said pillar is through the vertical manger shape integral body that connects into base plate of screw 9; Said annular slab is through the pillar pin joint of bearing pin 1 with both sides, and the circle ring center of said annular slab is equipped with the plectane 7 of card engaging workpiece, is bolted with adjustment studdle 8 on the said base plate; Said adjustment studdle quantity is four, and the position that is square is screwed onto on the base plate.Said plectane places adjustment studdle end face top, is provided with the free gap between the plectane of said card engaging workpiece and the adjustment studdle end face.The plectane of said card engaging workpiece is through the annulus pin joint of housing screw 3 with annular slab.The plectane upper surface of said card engaging workpiece is provided with through screw 10 connected pressing plates 2.Said pressing plate is connected the surface and is provided with and compresses inclined-plane 2-1 with workpiece, the workpiece loading and unloading frock hole of only need packing into rotates to and gets final product below the inclined-plane during porting, also only needs reverse rotation can take out workpiece when unloading workpiece, has saved the work that stubborn bolt compresses and unclamps fully.The plectane center of said card engaging workpiece is provided with frock hole 12, and said base plate center is provided with technology via hole 13.
The course of work:
Floating type porting anchor clamps make full use of the rotation friction and the inclined-plane self-lock mechanism of porting.Floating type porting anchor clamps and the supporting use of ultra smart hole abrading machine (also can generally be used for other bench drill, grinder etc.).Rotate under 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 attrition process finishes back reverse rotation workpiece workpiece is taken out the completion attrition process from the hole of plectane.Several hang-ups more than the successful development of the porting frock of should floating has been captured at one stroke, the operator only needs to get final product toward the frock lifting workpiece, greatly reduces the requirement of operator's technical ability with muscle power, has also shortened the time that the operator contacts with lapping liquid greatly simultaneously.Because this frock can 360 ° of free floatings, the product hole circle degree 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 invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
