Abstract

The utility model relates to a two-way tapping clamp, which comprises a clamp base, an upper clamp, a lower clamp, and so on. The two-way tapping clamp is characterized in that grooves matched with the cross section of a processed workpiece are formed on the jaw surfaces of the upper clamp and the lower clamp respectively, and an opening is formed above the groove of the upper clamp. The two-way tapping clamp is used in an automatic tapping machine and can finish two tapping tasks with intersected directions, without need of installation for multiple times, so as to remarkably improve production efficiency and ensure high enough position accuracy and dimensional accuracy.

Description

Two-way tapping clamp

Technical field

The utility model relates to a kind of clamping device that is used for machining, particularly the multistation rotary table grip device in the automatic tapping machine.

Background technology

Commonly used to the part that comprises the cross bore structure on precision components such as electrical equipment, as binding post etc., this part is all porose on two orthogonal directions, and all comprises internal thread.For this when all female part of both direction carries out tapping majority all be to adopt manual operations or automanual mode, after carrying out the punching and typing processing of a direction, forward the tapping processing that next work step carries out another direction again to, this processing method not only needs many process equipments, need multiple clamping, and in process, transport, thereby cause production efficiency low, the machining accuracy of the higher workpiece of ask for something is difficult to guarantee.The anchor clamps that use on the tapping machine, very big to the influential effect of tapping, existing anchor clamps can only be finished the tapping processing of a direction after clamping, thereby can not finish the tapping processing of both direction at a clamping.

The utility model content

The purpose of this utility model is to provide a kind of two-way tapping clamp that can finish a plurality of direction tapping processing in a clamping.

Two-way tapping clamp of the present utility model is achieved in that two-way tapping clamp, include holder, upper grip and lower chuck, respectively have the groove that cooperates with the work piece cross section on the vice jaw surface of upper grip and lower chuck, there is an opening groove top of upper grip.

The groove shapes of the above-mentioned upper grip and the vice jaw surface of lower chuck is circular.

The opening of the groove top of above-mentioned upper grip is a through hole.

There is a top board above-mentioned lower chuck below, between lower chuck and top board holddown spring is installed.

Respectively have the bottom outlet of placing holddown spring on above-mentioned lower chuck and the top board.

Be provided with internal thread in the bottom outlet of above-mentioned top board, and screw is installed, the screw top braces is in the spring bottom.

The utility model is installed on the automatic tapping machine and uses, can carry out tapping processing from the side, can hole or tapping processing to crisscross downwards from the top again simultaneously, thereby can in a clamping, finish the tapping work of both direction, need not workpiece is repeatedly installed, improved production efficiency greatly, and can guarantee sufficiently high positional precision and dimensional accuracy, the utility model is simple in structure, and is easy to use.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, referring to Fig. 1-7:

Two-way tapping clamp partly is made up of holder 1, upper grip 2, lower chuck 3 etc., and holder 1 can be fixed on the rotary table periphery of automatic tapping machine; Upper grip 2 is fixed into one with holder 1, its thickness is less, lower chuck 3 is positioned at holder 1 and connects with pull bar 4 upper ends pin, pull bar 4 lower ends are stretched out holder 1 and are connected with touching lever 5 tips, holder 1 is stretched out at the top of lower chuck 3, the thickness of extending area is identical with the thickness of upper grip, last lower chuck 2, each correspondence of the face that clamps together of 3 has

groove

21,31, when clamping together, both piece together given shape, with the clamping blank, there is an opening 22 the groove top of upper grip 2, opening is less than the maximum spot size of groove, and there is a top board 6 lower chuck 3 belows, in the bottom surface of lower chuck 3 diagonal two bottom outlets 32 is arranged, holddown spring 7 is installed in the hole, the other end of holddown spring 7 pushes up mutually with top board 6, also has spring on the top board 6 bottom outlet is installed, and has screwed hole on bottom outlet, and soket head cap screw 8 is installed, the through hole of opening on the top board 6 of soket head cap screw 8 tops and the lower chuck 3 can stretch into the spanner rotary screw to regulate the elastic force of 8 pairs of lower chucks 3 of holddown spring.

Holder 1 has the guide pillar hole that diagonal distributes, and guide pillar 9 passes the guide pillar hole and is fixed on and is the guiding that moves up and down of lower chuck 3 on the holder 1, guarantee lower chuck 3 compress with back off procedure in operate steadily, accurately.

As shown in Figure 3, the open top position 22 of upper grip 2 is the holes from the downward sensible groove 21 in upper grip 2 tops.

When anchor clamps during at Working position, last

lower chuck

2,3 clamps together work piece binding post 10 is clamped, processing such as the cutter of horizontal direction can be holed, chamfering, tapping, and the cutter of vertical direction can by the top by upper grip 2 opening finish processing such as boring, chamfering, tapping downwards, when anchor clamps forward to when changing the part position, touching lever 5 is subjected to the effect of the relative power of push rod or touching column, driving lower chuck 3 by pull bar 4 againsts the force of the spring moves down,

lower chuck

2,3 is separated, and finished product is ejected.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
