Abstract

The utility model discloses a ram guide rail inclined surface grinding fixture, and relates to the technical field of mechanical equipment. The ram guide rail inclined surface grinding fixture comprises a base seat and a clamping arm. A top portion clamping surface of the base seat is an inclined surface, a boss is arranged at the lower end of the clamping surface, the clamping arm is arranged on a lateral surface of the base seat, and the top portion of the clamping arm extends to the upper end of the clamping surface. The base seat is fixedly connected with the clamping arm through threads. The clamping arm is provided with a mounting through groove, and the mounting through groove corresponds to a threaded hole in the base seat. The ram guide rail inclined surface grinding fixture is capable of solving the problems that the process of grinding a large V-shaped ram inclined guide rail is complex, adjustment is difficult, machining precision is low and machining efficiency is low.

Description

Ram gib angular surface grinding anchor clamps

Technical field

The utility model relates to plant equipment manufacturing technology field, especially a kind of anchor clamps for the processing of machine ram plurality of ramps.

Background technology

" V " type guide rail is a kind of distinctive guide rail form in the heavy duty machine tools ram gib greatly, as shown in Figure 1.When carrying out grinding, its specification requirement is high, should guarantee the correctness of its angle on the ram inclined-plane, guarantees again the depth of parallelism of itself and vertical guide rail and horizontal guide rail, and the depth of parallelism on two inclined-planes.

Existing technology is to adopt special-purpose guide rail grinding lathe, level up guide pass at platen with eight contour adjusting pad iron blocks and come large " V " shape ram gib inclined-plane of grinding, and before using the contour pad iron block, need to finish grind the contour pad iron block once, also need simultaneously to adjust grinding head grinding wheel angle of inclination and twice clamping ram gib face.Adopt this processing method to come large " V " type ram slant rail of grinding, the process complexity is loaded down with trivial details, adjusts difficulty, and machining accuracy is low, and working (machining) efficiency is low, and is high to workman's specification requirement.

The utility model content

Technical problem to be solved in the utility model provides a kind of ram gib angular surface grinding anchor clamps, and it is loaded down with trivial details that it can solve large " V " type ram slant rail process complexity of grinding, adjusts difficulty, and machining accuracy is low, the problem that working (machining) efficiency is low.

In order to address the above problem, the technical solution of the utility model is: this ram gib angular surface grinding anchor clamps include base and jig arm; The top clamping face of described base is the inclined-plane, and the lower end of described clamping face is a boss, and described jig arm is located on the side of described base, and the top of described jig arm extends the upper end of described clamping face.

In the technique scheme, more specifically scheme can also be: described base by thread is fixedly connected with described jig arm.

Further: described jig arm is provided with one groove is installed, and it is corresponding with the screwed hole on the described base that this installs groove.

Owing to adopting technique scheme, the utlity model has following beneficial effect:

1, the top clamping face of base of the present utility model is the inclined-plane, the lower end of clamping face is a boss, clamping face is as the datum level of mounting parts, regulate the length of clamping face by the jig arm that is contained in the base side, large " V " type ram is placed on the anchor clamps, and clamps with jig arm and stud, the angle grinding is transformed to the horizontal plane grinding, cross grinding is transformed to peripheral grinding, has improved grinding accuracy and the fineness of guide pass.

2, the processing mode of the utility model employing has reduced repeatedly centering of workpiece, thereby saves process time, improves working (machining) efficiency, and can easily realize the slant rail face grinding to ram on surface grinding machine.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

Shown in Figure 1 is large " V " type guide rail of heavy duty machine tools ram.

Ram gib angular surface grinding anchor clamps shown in Figure 2 include base 4 and jig arm 5; Such as Fig. 3, Fig. 4 and shown in Figure 5, the top clamping face 4-1 of base 4 is the inclined-plane, and the lower end of clamping face 4-1 is a boss 4-4, and jig arm 5 is located on the side of base 4, and the top of jig arm 5 extends the upper end of clamping face 4-1.

Clamping face 4-1 is as the datum level that ram gib 9 is installed, and boss 4-4 will fill ram gib 9 and be positioned on the clamping face 4-1, is provided with tapped through hole 4-2 perpendicular to the side of described clamping face 4-1, and base 4 both sides are provided with U-shaped holddown groove 4-3 in the lower surface; T-shaped grooved screw 1 passes U-shaped holddown groove 4-3 and with packing ring 2 and nut 3 base 4 is fixedly connected with platen; Such as Fig. 6, Fig. 7 and shown in Figure 8, jig arm 5 has an inclined platform 5-1 peace boss 5-2, establish one between two boss groove 5-3 is installed, the inclined platform 5-1 of jig arm 5 is pressed on the ram gib 9, plano-convex platform 5-2 is pressed on the base 4, passes installation groove 5-3 and the packing ring 7 in the jig arm 5 and add high nut 8 by stud 6 ram gib 9 is fastened on the base 4.Can carry out grinding to ram gib 9 after fixing.
