Abstract

The utility model relates to a joint drilling fixture, and belongs to a machine tool fixture. The joint drilling fixture comprises a base seat, a fixed seat, a guide plate, a nut seat, a lock screw, a limit board and a fill block. The fixed seat is connected to the right portion of the base seat. The base seat is connected with the left portion of the base seat. The lock screw is screwed on the nut seat. The guide plate is compressed tightly on the fixed seat through a regulating screw. The limit board is connected to the back of the fixed seat. A limit screw is screwed on the limit board. Guide holes are arranged on the guide plate. The left side of the fixed seat is connected with a baffle. A first V-shaped groove is formed in the left side surface of the baffle, wherein the first V-shaped groove is used for being attached to two withdrawing pattern inclined planes of a joint end of a joint workpiece blank piece. A second V-shaped groove is formed in the right side surface of the fill block, wherein the second V-shaped groove is used for being attached to the two withdrawing pattern inclined planes of the joint end of the joint workpiece blank piece. The joint drilling fixture has the advantages that the joint workpiece blank piece can be clamped directly, working procedures of milling end surfaces of three joint ends of the joint workpiece blank piece in a milling machine are saved, working efficiency is improved, and production cost is reduced.

Description

The joint boring grab

Technical field:

The utility model relates to a kind of jig, is specifically the joint boring grab that uses on a kind of drilling machine.

Background technology:

as shown in Figure 4 and Figure 5, the joint boring grab of prior art comprises base 110, holder 109, guide plate 108, nut seat 102, tie down screw 101, limiting plate 105 and cushion block 103, holder 109 is connected to the right part on base 110, nut seat 102 is connected to the left part on base 110, tie down screw 101 is spun on nut seat 102, guide plate 108 is pressed on holder 109 by adjustment screw 107, limiting plate 105 is connected to the back of holder 109, be rotary with stop screw 104 on limiting plate 105, guide plate 108 is provided with pilot hole 106, during use, the joint workpiece first is clamped between holder 109 and cushion block 103, the effect of cushion block 103 is in order not make tie down screw 101 weigh the joint workpiece wounded, the back of joint workpiece abuts on stop screw 104, guiding by the pilot hole 106 on guide plate 108 can get out the through hole 113 on the joint workpiece again, because the contact-making surface of holder 109 and cushion block 103 and joint workpiece is the plane, this just requires the contact-making surface of processed joint workpiece also to be the plane, and the blank of the joint workpiece that casts out is generally to have three tip sides 111, the end face of each tip side 111 is not the plane, form but be rightabout withdrawing pattern inclined-plane 112 by two, therefore, the joint workpiece just directly clamping on the joint boring grab, and require the blank of joint workpiece first flat the facing cut of three tip sides 111 on milling machine before boring, do so just cumbersome, also increased production cost.

The utility model content:

The technical problems to be solved in the utility model is to provide a kind of need not first the facing cut of three tip sides of the blank of joint workpiece both to be put down the directly joint boring grab of clamping.

technical solution of the present utility model is, provide a kind of joint boring grab with following structure: comprise base, holder, guide plate, nut seat, tie down screw, limiting plate and cushion block, holder is connected to the right part on base, nut seat is connected to the left part on base, tie down screw is spun on nut seat, guide plate is pressed on holder by adjustment screw, limiting plate is connected to the back of holder, be rotary with stop screw on limiting plate, guide plate is provided with pilot hole, wherein, the holder left side is connected with baffle plate, the baffle plate left surface is provided with for the first V-type groove of fitting with two withdrawing pattern inclined-planes of the tip side of joint workpiece blank, the right flank of cushion block is provided with for the second V-type groove of fitting with two withdrawing pattern inclined-planes of the tip side of the blank of joint workpiece.

Joint boring grab described in the utility model, wherein, the bottom of the first V-type groove is provided with groove.

after adopting above structure, compared with prior art, the utility model joint boring grab has the following advantages: owing to being connected with baffle plate on the left of holder, the baffle plate left surface is provided with for the first V-type groove of fitting with two withdrawing pattern inclined-planes of the tip side of joint workpiece blank, the right flank of cushion block is provided with for the second V-type groove of fitting with two withdrawing pattern inclined-planes of the tip side of the blank of joint workpiece, therefore, the tip side of the joint workpiece blank left and right sides can directly be clamped between the first V-type groove and the second V-type groove on cushion block on baffle plate, during through hole on the tip side in the middle of the working joint workpiece blank spare, the utility model joint boring grab also can be clamped in the face of cylinder on the tip side in the middle of joint workpiece blank and its opposite between the first V-type groove and the second V-type groove on cushion block on baffle plate, saved on milling machine the flat operation of facing cut of three tip sides of the blank of joint workpiece, improved operating efficiency, reduced production cost.

Reeded effect is established in the bottom of the first V-type groove: between two withdrawing pattern inclined-planes of the tip side of joint workpiece blank owing to being the die joint of mould and easily produce burr, when clamping the blank of workpiece, burr can extend in the groove that the bottom of the first V-type groove is provided with, can not affect the location of the first V-type groove, thereby can not affect the positional precision of boring.
