Abstract

The utility model discloses a vertical grinding suspension grinding clamp for mould ring, belonging to the mould making field and comprising a clamp component. The clamp component comprises a rectangular base plate whose four sides are provided with grooves. Four clamping blocks that are clamped with the workpieces in the base plate by screws are symmetrically placed in the grooves, and four bearing blocks are symmetrically placed at the lower part of the base plate along the diagonal. The clamp eliminates the over proof phenomenon of depth of parallelism produced by grinding of the mould ring directly adsorbing on the magnetic workbench, makes the depth of parallelism of the mould ring reach the technical requirement (<= 0. 05mm), and satisfies the production emergency. The clamp is simple, safe, reliable, and with flexible operation and less consumable material, and provides safeguard for the accurate regrinding of the hollow workpieces such as mould ring.

Description

The floated clamp of Vertical Mill that is used for the mould circle

Technical field

The utility model belongs to mould manufacturing field, specially refers to a kind ofly on vertical grinder, also can be on non-vertical grinder, to the floated clamp of hollow class objects such as mould circle.

Background technology

In the kinescope glass shell die assembly, the mould circle is an important component part, (the line of its manufacturing process's complexity, the car face, corase grind is beaten ∮ 8 datum holes, the roughing inner chamber, heat-treatment of annealing is beaten ∮ 10 datum holes, correct grinding, Digit Control Machine Tool fine finishining inner chamber, Cutter Body Processing with Machining Center guiding, pincers worker is ground, and measures, and sandblasts, electroplate, etc. operation); The required precision height: up and down two and the depth of parallelism require very strict, in the required precision 0.05mm; The inner chamber contour accuracy requires in the 0.05mm.The mould circle uses a period of time under HTHP after, produce to a certain degree distortion, change in size is bigger, and precision is overproof bigger, needs Digit Control Machine Tool to repair usually, will carry out reconditioning earlier to the mould circle usually before the repairing.The way that adopts in the prior art in past is, the mould circle directly is adsorbed on the Vertical Mill disk workbench, owing to influenced by extraneous factor in the use of mould circle before reconditioning, as: weld the generation gross distortion that is heated, top and bottom are uneven, after disk absorption (suction reaches 2T), produced strain (as Fig. 2), the magnetic force that the finishes to be ground back mould circle strain that disappears is recovered (as Fig. 3), cause the depth of parallelism overproof (〉=0.2mm), had a strong impact on production.Simultaneously, the non-flour milling of workpiece all contacts with work top, goes up workpiece at every turn and all need sweep the cleaning table top comprehensively, and service working time is long, and workpiece and workbench form a groove in the grinding process, and unfavorable and backflow and row cutting fluid cut.Based on above-mentioned situation, need to cooperate anchor clamps to be overcome, we pass through experimental study repeatedly, develop a kind of simple and easy, flexible operation, safe and reliable, and the anchor clamps that consumptive material is less have guaranteed the depth of parallelism of mould circle after grinding.

Summary of the invention

The utility model technical issues that need to address are, directly be adsorbed on the Vertical Mill disk workbench at mould circle in the past, because mould circle gross distortion in use, top and bottom are uneven, produced strain after the disk absorption, mould circle strain was recovered after the magnetic force that finishes to be ground disappeared, existing causes the depth of parallelism overproof, have a strong impact on many defectives such as production, in order to overcome these defectives, the purpose of this utility model is to provide a kind of floated grinding anchor clamps of Vertical Mill that are used for the mould circle, this purpose is to rely on following technical scheme to realize that the floated mould circle of a kind of Vertical Mill clamp comprises clamping part, it is characterized in that, this clamping part contains a rectangular substrate, has groove on four sides of substrate, four clamps of symmetrical respectively placement in the groove, clamp by screw and the workpiece that places substrate, four lip blocks are placed along symmetry on the diagonal in the substrate bottom.Described substrate is by 45# aluminium mill, long 850mm * wide 720mm * thick 30mm.Described clamp, it is shaped as L shaped, and this clamp height is 160 ± 0.02mm, clamps by screw in the silk hole above it and mould circle.∮ 13 through holes that have counterbore are arranged below this clamp, clamp is fixed on the flat board by the M12 screw; By these anchor clamps in use with mould circle " suspension " in anchor clamps, and be adsorbed in and carry out grinding on the magnetic force workbench with device.The beneficial effects of the utility model are to have eliminated because of the mould circle directly is adsorbed on the depth of parallelism off-gage phenomenon that grinding produced on the magnetic force workbench, make the mould circle depth of parallelism reach specification requirement (≤0.05mm), satisfied and produce to be badly in need of.These anchor clamps are simple and easy, flexible operation, safe and reliable, and consumptive material is less, for the accurate reconditioning of hollow class objects such as mould circle provides guarantee.

Description of drawings

Fig. 1 is in the known technology, and grinding workpiece directly is adsorbed on the attached workbench schematic diagram of magnetic;

Fig. 2 is for press Fig. 1 described, and grinding finishes after magnetic force disappears, strain recovery schematic diagram;

Fig. 3 is this floated clamp work schematic diagram;

Fig. 4 is L shaped clamp structure chart.

The specific embodiment

With reference to Fig. 1, Fig. 2, represent the front and back state of traditional grinding, grinding workpiece directly is adsorbed on the attached workbench of magnetic and carries out grinding, grinding workpiece is a mould circle 2 among the figure, grinding allowance is 7, and workpiece directly is adsorbed on the attached workbench 6 of grinding machine magnetic, and elastic deformation can't meet the demands the depth of parallelism after the grinding.With reference to Fig. 3, expression the design is used for the floated mould circle of Vertical Mill grinding anchor clamps, clamp 1 is separately positioned on the side concave part of four symmetries of substrate 4 among the figure, rely on screw 3 that workpiece is stepped up, it is fast 5 to be lined with 4 pads between workpiece 2 and the substrate 4, with reference to Fig. 4, represents L shaped clamp, has a hole 8 on the L shaped face among the figure, the through hole 9 that has the band counterbore on another face is wiped clean cushion block 5 and is placed on dull and stereotyped 4, and mould circle 2 is placed in the anchor clamps, compacting is on cushion block 5, fastening with the screw on the clamp 13 by M16 silk hole, be suspended at grinding on the Grinder bench 6 then, grinding finishes, mould circle 2 is taken out, and anchor clamps are put back to assigned address.
