Abstract

The utility model discloses a connecting rod machining fixture. The fixture comprises a bottom plate (1), wherein a vertical plate (2) is arranged on the bottom plate (1), a fixture base (3) is arranged on one side of the vertical plate (2), and a stop block (6) for positioning a connecting rod and a positioning pin (7) matched with a small head hole of the connecting rod are arranged on the fixture base (3); a clamping mechanism is also arranged on the fixture base (3) and comprises a press plate (4), a strut mounting hole is formed nearby the middle of the press plate (4), a strut (5) is arranged on the fixture base (3), and the strut mounting hole is matched with the strut (5) and enables the press plate (4) to swing around the strut (5); one end of the press plate (4) is a press end, and a propping mechanism for propping the other end is arranged at the other end. Clamping is realized by using the seesaw principle, and all that is required for clamping each time is to switch on a servo motor (11) instead of assembling and disassembling the whole fixture, so that the clamping efficiency is high, and the production efficiency is improved greatly.

Description

A kind of connecting rod processing clamp
Technical field
The invention belongs to Machining of Connecting Rod apparatus field, relate in particular to a kind of connecting rod processing clamp.
Background technology
Conventional linkage clamp for machining adopts the locate mode that alignment pin and block are set on base plate, and clamp mechanism adopts bolted, and connecting rod of every processing will fixture of dismounting, and working (machining) efficiency is low, and labour intensity is large, has reduced production efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenient mounting and clamping, connecting rod processing clamp that working (machining) efficiency is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of connecting rod processing clamp, comprise base plate, and described base plate is provided with riser, described riser one side is provided with clamp base, described clamp base be provided with positioning linkage rod block and with the suitable alignment pin of connecting rod small end hole; In described clamp base, be also provided with clamp mechanism, described clamp mechanism comprises pressing plate, and described pressing plate near middle is provided with pillar installing hole, and described clamp base is provided with pillar, and described pillar installing hole and pillar are suitable, and pressing plate can be swung around pillar; Described pressing plate one end is for compressing end, and the other end is provided with the jacking mechanism that holds out against this end;
Described jacking mechanism comprises pull bar, and described pull bar is through riser and clamp base, and one end of pull bar contacts with one end of pressing plate, and the other end is provided with tooth bar, and base plate is provided with servomotor, and described servomotor output shaft is provided with the gear being meshed with tooth bar.
The output shaft of described servomotor is arranged on the bearing block on base plate, on described pillar, is set with spring, and described spring one end contacts with clamp base, and the other end contacts with pressing plate.
Described riser is provided with the through hole corresponding with crank pin end pore with clamp base.
Pillar installing hole quantity on described pressing plate is no less than two.
Described pillar installing hole is oval, and the aperture of pillar installing hole is greater than the diameter of pillar.
Described riser is connected with clamp base bolt.
The invention has the advantages that, clamp mechanism utilizes the principle of seesaw, by holding out against pressing plate one end, and make the pressing plate other end compress connecting rod, and realize clamping, each clamping only need to be opened servomotor, and not needing whole remover-and-replacer, clamping efficiency is high, has greatly improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of connecting rod processing clamp of the present invention;
Fig. 2 is the structural representation of Fig. 1 connecting rod processing clamp;
Mark in above-mentioned figure is: 1, base plate, 2, riser, 3, clamp base, 4, pressing plate, 5, pillar, 6, block, 7, alignment pin, 8, pull bar, 9, tooth bar, 10, gear, 11, servomotor.
The specific embodiment
Fig. 1 and Fig. 2 are the structural representation of a kind of connecting rod processing clamp of the present invention, comprise base plate 1, and base plate 1 is provided with riser 2, and riser 2 one sides are provided with clamp base 3, clamp base 3 be provided with positioning linkage rod block 6 and with the suitable alignment pin 7 of connecting rod small end hole; In clamp base 3, be also provided with clamp mechanism, clamp mechanism comprises pressing plate 4, and pressing plate 4 near middles are provided with pillar installing hole, and clamp base 3 is provided with pillar 5, and pillar installing hole and pillar 5 are suitable, and pressing plate 4 can be swung around pillar 5; Pressing plate 4 one end are for compressing end, and the other end is provided with the jacking mechanism that holds out against this end;
Jacking mechanism comprises pull bar 8, and pull bar 8 is through riser 2 and clamp base 3, and one end of pull bar 8 contacts with one end of pressing plate 4, and the other end is provided with tooth bar, and base plate 1 is provided with servomotor 11, and servomotor 11 output shafts are provided with the gear 10 being meshed with tooth bar 9.
The output shaft of servomotor 11 is arranged on the bearing block on base plate 1, on pillar 5, is set with spring, and spring one end contacts with clamp base 3, the other end contacts with pressing plate 4, because pillar 5 is matched in clearance with pillar installing hole, spring can hold out against pressing plate 4, makes that pressing plate 4 is unlikely to be rocked on pillar 5.Riser 2 is provided with the through hole corresponding with crank pin end pore with clamp base 3, and boring cutter can pass through this through hole, and can play chip removal effect.
Pillar installing hole on pressing plate 4 can arrange a plurality of, and to be suitable for the connecting rod of different size, versatility is high.
Pillar installing hole is oval, and the aperture of pillar installing hole is greater than the diameter of pillar 5, thereby pressing plate 4 can be swung around pillar 5.Riser 2 is connected with clamp base 3 bolts.
Adopt after such structure, clamp mechanism utilizes the principle of seesaw, by holding out against pressing plate 4 one end, and make pressing plate 4 other ends compress connecting rod, realize clamping, each clamping only need to be opened servomotor 11, band carry-over bar and pull bar 8, and do not need whole remover-and-replacer, automaticity is high, clamping efficiency is high, has greatly improved production efficiency.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
