Abstract

The invention discloses a clamp tool mechanism, belongs to clamp technology, and in particular relates to a labor-saving clamp tool for assembling a massive workpiece. The clamp tool mechanism comprises a base, a support pillar and the like, and is characterized in that: a slot is formed on the base of the clamp at 90-DEG intervals, so that the support pillar can be fixed at the four positions. A hole which can be provided with a rotating bolt is formed on the support pillar of the clamp; two ends of the rotating bolt against the support pillar are provided with two plastic gaskets; a lock nut is screwed at one end with a thread, and a rotating arm is welded at the other end; the rotating arm is positioned by a positioning latch and can be fixed at the two positions; after a bracket is fastened on the rotating arm by using a screw, an elongated slot is formed on the bracket and used for placing a clamp head; a hole is formed at one end of the bracket; and the clamp head is connected with the bracket by using a clamp head rotating pin, so that the clamp head is rotated freely in the elongated slot of the bracket and can be fixed at the three positions.

Description

A kind of clamp tool mechanism

Technical field:

The invention belongs to clamp technology, particularly designed the laborsaving makeup folder apparatus when being used to assemble large-mass workpiece.

Background technology:

Existing workpiece generally adopts the streamline pattern when assembling parts, and in the process of assembling, need carry out actions such as many kinds times move, rotation to workpiece, to guarantee each parts interior of can packing into smoothly, reaches the purpose of combination.In general, for the workpiece of little quality, many kinds times move waits action can't waste great strength with the time just can realize, and is directed against the workpiece of big quality, and the manual work that the general clamp tool that all can adopt some laborsavingization reduces pilot process is wasted.

Summary of the invention:

The objective of the invention is to design the laborsaving makeup folder apparatus when being used to assemble large-mass workpiece.

The present invention includes clamp base, support column, location limit piece, knob, rotation double-screw bolt, plastic spacer, locking nut, turning arm, fastening screw, spring, support, dop rotating dog, anchor clamps dop, dop alignment pin, dop latch; It is characterized in that every interval 90 degree are opened a groove on clamp base; Can make support column in these four fixed-site; Be stuck in the groove with location limit piece then, lock with knob again.A hole is opened on the plane on clamp base, and the multidiameter of one of support column is placed wherein, depresses location limit piece in certain position that needs of four positions, again with knob locking, and can the fixing branch dagger.

On the support column of anchor clamps, open a hole that the rotation double-screw bolt can be installed then; Be close to support column at the two ends of rotation double-screw bolt and place two plastic spacers; At the threaded end locking nut of screwing on; Turning arm is gone up in other end welding, and the location of turning arm is realized having two positions to fix by fastening screw.Its concrete realization is on support column, to open a hole to come the installing and locating latch, and spring housing on fastening screw, is sealed in the hole, at initial position then; In the corresponding aperture that injects on the turning arm with fastening screw, fixedly turning arm is outwards extracted fastening screw; Turning arm gets final product the Rotate 180 degree, unclamps fastening screw, under the reset response of spring; Fastening screw injects in another corresponding aperture on the turning arm once more, also can limit the rotation of turning arm, and this is second position.

After being fastened on support on the turning arm with screw, on support, open an elongated slot, be used to place the anchor clamps dop; Open a hole at an end of support, the anchor clamps dop is connected together with support, the anchor clamps dop is freely rotated in the elongated slot of support through the dop rotating dog; There are three positions to fix, the one, with the dop alignment pin support is connected together with the anchor clamps dop, with the stationary fixture dop; The 2nd, after unclamping the dop alignment pin, the anchor clamps dop can make progress or freely rotate downwards, after turning over 90 degree; Dop latch at the support another side is fixed the anchor clamps dop automatically, and this has two positions to fix.

Anchor clamps principle according to the invention is simple; Can fix four positions in order to work through the support column rotation, can fix two positions in order to work, can fix three positions again in order to work through the dop rotating dog through the rotation double-screw bolt; Can satisfy the convenient for assembly of each position; Not only laborsaving but also easy left-hand seat, the time of upset workpiece has been improved production efficiency when greatly shortening assembling.

Description of drawings:

Fig. 1 is the clamp mechanism schematic perspective view;

Fig. 2 is the clamp mechanism front view.

The specific embodiment:

With reference to Fig. 1, Fig. 2, every interval 90 degree are opened a groove on clamp base 1, can make support column 2 in these four fixed-site, are stuck in the groove with location limit piece 3 then, again with knob 4 lockings.On the support column 2 of anchor clamps, open a hole that rotation double-screw bolt 5 can be installed then; Be close to support column at the two ends of rotation double-screw bolt 5 and place two plastic spacers 6; At the threaded end locking nut 7 of screwing on; Turning arm 8 is gone up in other end welding, and the location of turning arm 8 is realized having two positions to fix by fastening screw 9.After being fastened on support 11 on the turning arm 8 with screw at last; On support 11, open an elongated slot, be used to place anchor clamps dop 13, open a hole at an end of support 11; Through dop rotating dog 12 anchor clamps dop 13 is connected together with support 11; Anchor clamps dop 13 is freely rotated in the elongated slot of support 11, after turning over 90 degree, fix the anchor clamps dop automatically at the dop latch 15 of support another side.
