Abstract
The invention relates to a floating type hole lapping fixture which is characterized by comprising a bottom plate, a steel ball retaining plate, a connecting plate, a pressure plate and steel balls. The steel ball retaining plate and the connecting plate are sequentially arranged on the upper surface of the bottom plate, the steel ball retaining plate, the connecting plate and the bottom plate are connected with one another by rivets to form an integral floating body, a pressure plate mechanism is arranged in the center of the connecting plate, cylindrical holes are transversely arranged on the steel ball retaining plate at intervals and are close to two ends of the steel ball retaining plate, the steel balls are arranged in the cylindrical holes, and the thickness of the steel ball retaining plate is smaller than the diameter of each steel ball. The floating type hole lapping fixture has the advantages that when used for lapping a hole on a part with a high requirement on the verticality of a hole surface, the floating type hole lapping fixture guarantees that the part can float along with a tool after the part is fixed onto the tool, the verticality of the hole is qualified assuredly after the hole is machined, both the qualified rate of the dimensional precision and the qualified rate of the vertical accuracy are greatly increased as compared with the traditional tool, the qualified rate of the dimensional precision is increased by 50% at least, and the qualified rate of the vertical accuracy of the hole surface is at least 1.5 times of the qualified rate of the vertical accuracy of a hole surface machined by the traditional tool.
Description
Technical field
The invention belongs to frock clamp, relate in particular to a kind of floating type fine lapping fixture.
Background technology
During hole that lappingout precision component hole face vertical precision is had relatively high expectations, adopt at present screw or pressing plate to clamp, although this locate mode is simple, but have wretched insufficiency: the mode workpiece that tradition leans on screw or pressing plate to be fixed can not move, porting add hole face off plumb situation appears man-hour and can not automatic capturing, hole after causing processing is vertically defective, and percent defective is high.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of floating type fine lapping fixture to be provided, and the precision component that hole face vertical precision is had relatively high expectations adopts the lappingout processing mode that floats, and has improved product percent of pass.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of floating type fine lapping fixture, it is characterized in that: comprise base plate, steel ball holding plate, connecting plate, pressing plate and steel ball, described plate upper surface is equipped with steel ball holding plate and connecting plate successively, and connects into the integral body of floating by blind rivet, connecting plate central authorities are provided with press plate mechanism, described steel ball holding plate is provided with cylindrical hole near the lateral separation, two ends, is equipped with steel ball in the described cylindrical hole, and described steel ball holding plate thickness is less than diameter of the steel ball.
Described press plate mechanism comprises pressing plate, screw and adjusting jackscrew, and described pressing plate centre bore runs through screw, and described screw and connecting plate are spirally connected, the pressing back-end adjusting jackscrew that is spirally connected.
Described connecting plate is provided with shop bolt.
Beneficial effect: during hole that the lappingout part is vertically had relatively high expectations to the hole face, guarantee that part can float with frock after frock is fixing, guarantee that the hole perpendicularity after the processing is qualified, dimensional accuracy and vertical precision qualification rate have all had large increase than front traditional frock, wherein the dimensional accuracy qualification rate improves more than 50%, and hole face vertical precision qualification rate improves more than 1.5 times.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
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 fine lapping fixture, comprise base plate 1, steel ball holding plate 2, connecting plate 3, pressing plate 5 and steel ball 9, described plate upper surface is equipped with steel ball holding plate and connecting plate successively, and connect into unsteady whole by two parallel blind rivets 8, connecting plate central authorities are provided with press plate mechanism, described steel ball holding plate is provided with four or above cylindrical hole near the lateral separation, two ends, be equipped with steel ball in the described cylindrical hole, described steel ball holding plate thickness is less than diameter of the steel ball.Described press plate mechanism comprises pressing plate 5, screw 6 and regulates jackscrew 7, and described pressing plate centre bore runs through screw 6, and described screw and connecting plate are spirally connected, the pressing back-end adjusting jackscrew that is spirally connected.Described connecting plate is provided with shop bolt 4.
Operation principle
After a frock parts were connected by above-mentioned annexation, the pressured plate of workpiece was fixed on the connecting plate, realizes floating of all directions by steel ball and the gap between the steel ball holding plate during processing porting, thus the vertical precision requirement that guarantees to process the metapore face.
The course of work
(1) workpiece is fixed on the connecting plate by the pin direction
(2) by screw belt dynamic pressure plate workpiece pressing
(3) guarantee that connecting plate is with the processing free floating during porting
(4) unload workpiece and finish porting processing
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 does.
