Abstract

The utility model discloses a gear clamping mechanism, include base, push pedal and be located the left cylinder of base, the push pedal is located the base right side, and push pedal and base sliding connection, push pedal include relative left push pedal and right push pedal, the cylinder is connected with the push rod, the push rod links to each other with left push pedal, push pedal fixedly connected with in a left side goes up the rack, rack under the right side push pedal fixedly connected with, go up rack and rack down all with base sliding connection, it has the gear to go up to mesh between rack and the lower rack, gear revolve connects on the base. Through the rotation of gear, drive left push pedal and right push pedal move simultaneously, solve the unilateral and removed the anchor clamps of push pedal, translation rate is slow, problem that work efficiency is not high.

Description

A kind of gear clamp system

Technical field

This utility model relates to work pieces process field, particularly relates to a kind of workpiece clamping mechanism.

Background technology

On lathe process workpiece time, for make workpiece can reach regulation size, geometry and with other surfaces The technology requirements such as relative-position error, must position workpiece before processing, clamp.Fixture is to add man-hour for fastening rapidly work Part, makes lathe, cutter, workpiece keep the process unit of correct position relatively.That is frock clamp is that machining can not The parts lacked.

In machining manufacturing industry, locating clip clamper plays very important effect, it assures that workpiece relative to lathe, Cutters etc. are in correct position all the time, it is ensured that the concordance of work pieces process and crudy.Though existing this clamping device So can meet the clamping demand of workpiece to a certain extent, but actually used during, inventor finds that it there are still Following some shortcomings: 1, the fixture of unilateral mobile push pedal, translational speed is slow, and work efficiency is the highest；2, conventional with spring phase In conjunction with clamping device, it is necessary to make spring could clamp workpiece when being in compressive state, such clamping process need spring Applying the pressure of persistence, use cost increases and persistently pressure clamping makes whole cargo handling process complicated, handling inconvenience and self-locking Weak effect.

Utility model content

The purpose of this utility model is to provide a kind of gear clamp system, to solve the fixture of the mobile push pedal in one side, moves Dynamic speed is slow, the problem that work efficiency is the highest.

For achieving the above object, this utility model provides following technical scheme: a kind of gear clamp system, including base, Push pedal and be positioned at the cylinder of chassis left side, described push pedal is positioned on the right side of base, and push pedal is slidably connected with base, and push pedal includes relatively Left push pedal and right push pedal, described cylinder connect have push rod, described push rod to be connected with left push pedal, described left push pedal is fixedly connected with Upper rack, described right push pedal is fixedly connected with lower tooth bar, described upper rack and lower tooth bar and is all slidably connected with base, upper rack and Being engaged with gear between lower tooth bar, described pinion rotation is connected on base.

The principle of this programme is: starts cylinder, is placed between left push pedal and right push pedal by workpiece, is connected on cylinder Push rod promotes left push pedal to move right, and upper rack and left push pedal are fixed and be connected and upper rack is slidably connected with base, then upper rack Moving right, upper rack moves driven gear and rotates, and lower gear is slidably connected with base and fixes with right push pedal and is connected, therefore rotates Gear driven under tooth bar be moved to the left, the right push pedal being fixed on lower gear is moved to the left, and is clamped workpiece.

The advantage of this programme is: by the rotation of gear, drives left push pedal and right push pedal move toward one another simultaneously, solves list The fixture of side shifting push pedal, translational speed is slow, the problem that work efficiency is the highest.

Preferably, described base is provided with support seat, described support seat has and is available for the through hole that push rod passes, and arranges and props up Support seat increases a strong point to push rod, makes push rod more steady.

Preferably, described left push pedal and right push pedal opposite face are equipped with rubber layer, arrange the rubber layer workpiece for clamping Play a protective role.

Preferably, being provided with groove on the right side of described base, described left push pedal and right push pedal are slidably connected in groove, are used for limiting Make left push pedal and the moving range of right push pedal, be also beneficial to mobile.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model a kind of gear clamp system embodiment.

Detailed description of the invention

Reference in Figure of description includes: base 1, cylinder 2, upper rack 3, push rod 4, support seat 5, gear 6, Left push pedal 7, lower tooth bar 8, rubber layer 9, right push pedal 10.

The most as shown in Figure 1, a kind of gear 6 clamp system, including base 1, push pedal be positioned on the left of base 1 for embodiment Cylinder 2, described push pedal is positioned on the right side of base 1, and push pedal includes relative left push pedal 7 and right push pedal 10, described left push pedal 7 and the right side Push pedal 10 opposite face is provided with rubber layer 9, and described base 1 right side opening is fluted, and described left push pedal 7 and right push pedal 10 are positioned at groove In, described left push pedal 7 is fixedly connected with upper rack 3, and described right push pedal 10 is fixedly connected with lower tooth bar 8, described upper rack 3 and under Tooth bar 8 is all slidably connected with base 1, is provided with gear 6 between upper rack 3 and lower tooth bar 8, and described gear 6 is fixedly connected on base 1 On, described cylinder 2 connects has push rod 4, described base 1 to be provided with support seat 5, described support seat 5 has and is available for push rod 4 and passes Through hole, described push rod 4 is through supporting seat 5 and being slidably connected with supporting seat 5, and push rod 4 end is connected with left push pedal 7.

During use, start cylinder 2, workpiece is placed between left push pedal 7 and right push pedal 10, left push pedal 7 and right push pedal 10 Between rubber layer 9 surface of the work can be played a very good protection, push pedal through support seat 5, support seat 5 be push pedal provide The strong point, push pedal promotes left guide plate to move right in groove, and upper rack 3 and lower tooth bar 8 are all slidably connected on base 1, position Below left push pedal 7 and right push pedal 10, the left push pedal 7 of movement drives upper rack 3 to move right, and upper rack 3 engages band with gear 6 Moving gear 6 rotates clockwise, and the gear 6 of rotation drives lower gear 6 to be moved to the left, the right push pedal 10 being fixed on lower gear 6 to Move left, by moving towards while left push pedal 7 and right push pedal 10, realize the clamping to workpiece, solve unilateral mobile The fixture of push pedal, translational speed is slow, the problem that work efficiency is the highest.

Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic is at this Too much describe.It should be pointed out that, for a person skilled in the art, in the premise without departing from this utility model structure Under, it is also possible to making some deformation and improvement, these also should be considered as protection domain of the present utility model, and these are all without impact The effect of this utility model enforcement and practical applicability.The protection domain that this application claims should be with the content of its claim Being as the criterion, the detailed description of the invention in description etc. records the content that may be used for explaining claim.
