Abstract
The utility model belongs to an improved vernier caliper for a milling machine. The utility model is characterized in that a rotary circular shaft is arranged at the back of the vernier caliper, a graduated ring which can indicate the rotary angle of the vernier caliper is arranged on the circular shaft, a contact type displacing reading watch is arranged at the lower clamping mouth of a ruler seedling, and a lower clamping mouth is not arranged at a vernier caliper. When the utility model is arranged on a processing main shaft of the milling machine, the process position of a workpiece can be quickly and accurately found, the working procedure of line drawing of the workpiece is omitted, and the processing accuracy is increased.
Description
The utility model relates to a kind of improved vernier caliper, particularly a kind of vernier caliper that is suitable for the milling machine use.
Existing vernier caliper mainly is made of chi seedling, scale and secondary chi.This vernier caliper has been widely used in machining industry, in order to length, external diameter, internal diameter and the degree of depth of measuring workpieces.But this vernier caliper is difficult to measure the precision size of milling machine center cutter to the workpiece processing reference field.At present, with hole of milling machine processing, general earlier by manually on workpiece setting-out find out the center of circle, on milling machine spindle, load onto thimble then and go the center, change cutter processing at last.This method operation is many, is easy to generate the error effect machining precision.In order to improve machining precision, to reach just also will carry out preprocessing.
The purpose of this utility model is to provide a kind of easy to use, the special-purpose vernier caliper of the milling machine quick, that measuring accuracy is high.
Task of the present utility model goes to finish as follows: a bearing seat is vertically loaded onto, pack into bearing and a circular shaft in the scale back side at the scale of existing vernier caliper in bearing seat; The limb that can indicate the vernier caliper rotational angle of socket is equipped with elastic pressuring clamping device between circular shaft and the limb on circular shaft; Load onto a contact displacement readings table on bayonet socket under the chi seedling, the center line of its contact and circular shaft center line are at grade, and be and vertical with the circular shaft center line, and when scale was 0, its contact summit was on the center line of circular shaft; Scale is not set bayonet socket.
Description of drawings and utility model embodiment:
Fig. 1 is the front view of the special-purpose vernier caliper of milling machine.
Fig. 2 is the cut-open view of Fig. 1 vernier caliper along the A-A line.
In the accompanying drawing, (1) is the chi seedling, and (2) are scale, (3) be contact displacement readings table, (4) are circular shaft, and (5) are limb, (6) be the scale trip bolt, (7) are secondary chi, and (8) are secondary chi trip bolt, (9) be minitrim wheel, (10) be bearing, (11) are bearing seat, and (12) are gib screw, (13) be bearing cap, (14) are circlip.Contact displacement readings table (3) can adopt dial gauge or liquid crystal digital display meter.The external cylindrical surface of limb (5) is carved with 360 scales, and inner cylinder face has groove.On the circular shaft (4) and the contacted shaft shoulder of limb (5), have several apertures, the elastic pressuring clamping device that spring of packing into (15) and steel ball (16) are formed.The contact grooves of steel ball (16) and limb (5), make limb (5) and circular shaft (4) relative fixed together, do not rotate with vernier caliper, but when people rotate limb (5) with hand, limb (5) can rotate with respect to circular shaft (4) again, so that regulate the rotational angle of vernier caliper, engrave a graticule in scale (2) and limb (5) contact position, in order to indication vernier caliper rotational angle.Bearing (10) is selected single-row radial ball bearing for use, to improve the rotation precision of vernier caliper.
Use-case:
1, on one flat plate class workpiece, find out processing stand:
(1) workpiece (as shown in Figure 3) being placed on the milling machine platform, is benchmark with the platform, makes workpiece B face and platform parallel longitudinal, and fastening good workpiece.
(2) circular shaft (4) with vernier caliper is installed on the milling machine cutter adapter, vernier caliper is pulled to the C size, fastening good scale trip bolt (6), rotating milling machine table then moves handwheel and rotates vernier caliper, it is 0 that the contact of contact displacement readings table (3) is contacted with workpiece B face everywhere, this moment, circular shaft (4) center was the C size to the distance of B face, the screw that is tightened (12).
(3) rotate limb (5) with hand, make 0 of limb (5) graticule on the scale (2), unclamp gib screw (12), rotate vernier caliper, make 90 degree of graticule on the limb on the scale (2), screw (12) again is tightened.
(4) vernier caliper is pulled to the D size, trip bolt (6) on the fastening good scale, move forward and backward worktable, the contact of contact displacement readings table (3) is just contacted with workpiece A face, at this moment, the center line of milling machine machining spindle just in time by the E point, unloads vernier caliper, changes cutter processing and just can.
2, on round piece, find out center or process a center pit:
(1) workpiece (as shown in Figure 4) is lain on the milling machine workbench and clamping.
(2) circular shaft (4) with vernier caliper is installed on the milling machine machining spindle, and vernier caliper is pulled to the 1/2D size, screws trip bolt (6).
(3) allow the contact of contact displacement readings table (3) just contact the face of cylinder of round piece, then vernier caliper is turn 90 degrees, allow the contact face of cylinder of contact workpiece just of contact displacement readings table (3) again, at this moment, the center line of milling machine machining spindle is concentric with round piece.Whether concentric for checking, can unclamp trip bolt (12), allow vernier caliper do 360 degree rotations, if it all is 0 that the contact of contact displacement readings table (3) contacts with the face of cylinder of round piece, then the milling machine machining spindle is concentric with round piece, unloads vernier caliper, changes cutter processing and just can.
In addition, utilize this vernier caliper,, can measure the verticality of side surface of workpiece by moving up and down milling machine table.
The utility model is used on the milling machine, can save some workpiece crossed process, has quick, precision advantage high and easy to use. In addition, the utility model is simple in structure, makes easily, is easy to apply.
