Abstract

The utility model relates to a clamp for bar-shaped material cutting blade, which belongs to the machining auxiliary equipment. The clamp comprises a disk (1) and a pin (5), a cutting blade (6) is connected with the disk (1) through the pin (5), and the disk (1) is clamped on a lathe. The clamp has the advantages that the structure is simple and compact, and the clamping is convenient; the cuttingblade is positioned through the clamp without the need of centering the original central line of the cutting edge of the cutting blade, the positioning is accurate, and the precision is high; the cutting edges of two cutting blades can be processed simultaneously, the sizes of the processed cutting edges of the two cutting blades form an entire circle, therefore, subsequent measurement can be convenient, and the production efficiency is greatly improved.

Description

A kind of anchor clamps of excellent section bar material cutting knife plate

Technical field

The utility model relates to a kind of anchor clamps in the machining, especially relates to the anchor clamps of the knife plate cutting edge moulding of cutting rod section bar material.

Background technology

At present, in the process that excellent section bar material heating is implemented to forge, for long charge bar being converted to the material segment length that can be fit to utilize, the blank knife plate is one of them necessary tool.In order to save mould, to reduce cost, realize repeatedly to repair utilization, blank knife plate cutting edge mostly is semi-circular structure; When bringing into use, the knife plate radius of edge is less, and it is thinner to cut the bar format diameter; After treating the wearing and tearing of knife plate cutting edge, need to strengthen the knife plate radius of edge, can implement to shear thick specification bar.

In the process of existing mechanical processing knife plate cutting edge, adopt dividing head to implement the setting-out calibration earlier, on milling machine, centering is partly implemented in setting-out then, according to milling machine index dial high scale line knife plate is carried out equal indicative processing; The method centering time is longer, and particularly five five equilibrium knife plate cutting edge difficulty are big, and working (machining) efficiency is lower; And in the process of after the wearing and tearing of knife plate cutting edge, repairing again, be difficult to find accurately the center line of former knife plate cutting edge.

Summary of the invention

In order to overcome the problem that existing wearing and tearing cutting edge knife plate knife plate cutting edge center line in repair process is difficult to centering, the utility model discloses a kind of anchor clamps of excellent section bar material cutting knife plate, described anchor clamps are made up of the pie at a disk and disc centre place projection, have simple in structure, easy to operate and can be implemented in the effect of accurate position reconditioning knife plate cutting edge.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of anchor clamps of excellent section bar material cutting knife plate comprise disk and bearing pin, and described disc centre place one side is made as columnar projections, and the high spot center is a through hole, and four pin shaft holes are positioned on the concentric circles of disk projection outer rim and are distributed on the same center line of disk; Described knife plate is connected with disk by bearing pin, and described disk clamping is on lathe.

The anchor clamps of described excellent section bar material cutting knife plate, bearing pin adopts glade plane space to cooperate with the knife plate hole.

The anchor clamps of described excellent section bar material cutting knife plate, bearing pin is set to straight pin, taper bolt or ladder pin, and the two ends of bearing pin are provided with screw thread.

After adopting technique scheme, the beneficial effects of the utility model are:

The anchor clamps of excellent section bar material cutting knife plate described in the utility model, simple and compact for structure, convenient mounting and clamping; Cooperate with the knife plate hole by bearing pin, be convenient to location, mounting or dismounting, need not centering knife plate cutting edge, and can process two knife plate cutting edges simultaneously and two knife plate cutting edges processing are of a size of a full circle, be convenient to follow-up measurement, improved production efficiency greatly.

Description of drawings

Fig. 1 is a three-dimensional structure diagram of the present utility model.

Fig. 2 is the utility model user mode schematic diagram.

Among the figure: 1, disk; 2, centre bore; 3, pin shaft hole a; 4, pin shaft hole b; 5, bearing pin; 6, knife plate; 7, knife plate centre bore; 8, knife plate locating hole.

The specific embodiment

In conjunction with the accompanying drawings the utility model is further specified, but the following examples are not as to qualification of the present utility model;

Anchor clamps at the excellent section bar material cutting knife plate described in Fig. 1,2, comprise disk 1 and bearing pin 5, described disk 1 one side centers are made as columnar projections, and the high spot center is a through hole, and four pin shaft holes are positioned on the concentric circles of disk 1 protruding outer rim and are being distributed on the disk 1 same center line; Described knife plate 6 is connected with disk 1 by bearing pin 5, and described disk 1 clamping is on lathe; Bearing pin 5 adopts glade plane space to cooperate with the knife plate hole; Bearing pin 5 is set to straight pin, taper bolt, ladder pin, and the two ends of bearing pin 5 are provided with screw thread.

Because knife plate 6 cutting edges wearing and tearing, in the process of repairing, knife plate 6 cutting edge center lines are difficult to find accurately, are in the reason that five knife plate locating holes 8 of same center line are not easy to wear, be convenient to centering based on knife plate centre bore 7 and with the knife plate cutting edge, adopt the method that guarantees by anchor clamps to implement processing.

Design a disk, disk external diameter, columnar projections external diameter are respectively Φ 180mm, Φ 392mm, and purpose is to be convenient to clamping on C620, C630 lathe; Disc centre hole 2 is a Φ 90mm through hole, is convenient to lathe tool and passes through smoothly; Two knife plates 6 are passed corresponding two pin shaft hole a3, two knife plate centre bores 7 by four bearing pins 5, two pin shaft hole b4, two knife plate locating holes 8 of symmetry are positioned on the disk 1, four bearing pins 5 and two knife plate centre bores 7, two knife plate locating holes 8 adopt glade plane space to cooperate respectively, are convenient to the location, mounting or dismounting are convenient; For prevent that knife plate 6 cutting edges are come off by rotatory inertia in the Vehicle Processing process, security consideration is fixed knife plate 6 with bolt on the bearing pin 5 that passes two knife plate centre bores 7, and bearing pin 5 is equipped with the nut location in disk 1 one sides.On lathe, process a full circle simultaneously, i.e. two knife plate cutting edges, and need not the former knife plate cutting edge of centering, be convenient to measure; Whenever process two knife plate cutting edges, need, promptly only the bearing pin 5 at knife plate locating hole 8 places need be moved on to and close on a hole mutually, process next cutting edge once more knife plate 6 rotation directions.By anchor clamps location knife plate 6, need not the former center line of centering knife plate cutting edge, accurate positioning, precision height; Process two knife plate cutting edges simultaneously by lathe, improve 80% than former milling machine processing knife plate cutting edge efficient; Convenient mounting and clamping is a full circle after the processing of two knife plate cutting edges, is convenient to dimensional measurement.

Need to prove embodiment and the concrete size thereof selected for use in this article for open the purpose of this utility model, do not show that the utility model only limits to this size, will be appreciated that, originally be intended to comprise the overall dimension in the suitable scope of application.
