Abstract
The invention relates to a machine clamp, in particular to a pin clamp template. The pin clamp template comprises a base and a sliding plate, the sliding plate is in sliding connection with the base, a driving device for driving the sliding plate is arranged on the base, and a left clamping claw and a right clamping claw which are arranged in a mirroring mode are hinged to the sliding plate; the driving ends of the two clamping claws can be coincided, a pin is arranged above coincident parts of the driving ends of the two clamping claws and fixed to the base, a pressure spring is tightly attached to the position below the coincident parts of the driving ends of the two clamping claws, the free end of the pressure spring is fixedly connected with the sliding plate, and the driven ends of the two clamping claws are clamping ends. By means of pin clamp template, a clamp which enables the step for clamping workpieces on a movable base to be more simplified and enable the structure to be simpler is provided.
Description
Technical field
The present invention relates to mechanical clamp, be specifically related to a kind of pin fixture.
Background technology
In prior art, fixture is holding workpiece on the pedestal of movement, and one is divided into six steps, and 1. pedestal moves to assigned address, and 2. the jaw of pedestal stretches out, and moves to position to be held; 3. closed jaw, complete the clamping of workpiece, 4. pedestal moves assigned address; 5. unclamp jaw, place work piece; 6. jaw shrinks and is returned to position to be held.This process steps is too much, and step too much can cause clamp structure complicated, and such as this fixture will comprise mobile clip claw mechanism and clamping device.
Summary of the invention
The object of the present invention is to provide a kind of on mobile foundation holding workpiece step more simplify, the more simple fixture of structure.
The present invention is achieved by the following technical solutions: pin fixture, comprise pedestal and sliding panel, sliding panel and pedestal are slidably connected, pedestal is provided with the drive unit driving sliding panel, sliding panel is hinged with the jaw that two, left and right mirror image is arranged, wherein, the drive end of two jaws can overlap, the top of two jaw drive end intersection is provided with a pin, pin is fixed on pedestal, the below of the intersection of two jaw drive ends is glued with a stage clip, and the free end of stage clip is fixedly connected with sliding panel, and the driven end of two jaws is bare terminal end.
The invention has the beneficial effects as follows: jaw, under the driving of wheel and rack, stretches out pedestal, the drive end simultaneously due to jaw is closed under the effect of pin, and fixture of the present invention needs to stretch out jaw by existing fixture, moves to position to be held; Closed jaw, complete clamping work, merge into a step, this process is without the need to Electromechanical Control, only just can need be realized by pinion rotation, compare the work that the whole clamping process mentioned in background needs six steps to complete, only need four steps after using fixture of the present invention to replace jaw, it is respectively 1. pedestals and moves to assigned address, jaw is made to be positioned at below workpiece, 2. gear drive jaw stretches out and clamps, and 3. pedestal moves to the position of place work piece, and 4.Gear reverse drive, jaw loses chucking power and decontrols workpiece, and is retracted to original position.More corresponding structures can be reduced after saving step, make structure more simple, reduce manufacturing cost and the maintenance cost of jaw; Step also can reduce the time adding clamping of workpieces and spend after reducing simultaneously.
Further, pin is arranged on the mirror shaft of two jaws; The speed clamped about when jaw can be made to clamp closed is consistent with dynamics.
Further, sliding panel offers the skateboards slot coordinated with pin on two jaw mirror shafts, and the free end of stage clip is fixedly connected with the bottom land of skateboards slot; This structure is that pin coordinates comparatively succinct structure with jaw.
Further, drive unit is gear, sliding panel is fixed with the tooth bar coordinated with gear; The power that rack-and-pinion provides as drive unit is more stable compared with other actuating units.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of structure pin fixture template embodiment of the present invention;
Reference numeral: pedestal 1, gear 2, sliding panel 3, tooth bar 31, spring 4, stage clip 5, jaw 6, pin 7, a workpiece 8.
Detailed description of the invention
By reference to the accompanying drawings 1, pin fixture, comprise pedestal 1 and sliding panel 3, pedestal 1 is provided with gear 2, sliding panel 3 is fixed with the tooth bar 31 coordinated with gear 2, tooth bar 31 is fixed on sliding panel 3, sliding panel 3 and pedestal 1 are slidably connected, sliding panel 3 is hinged with two jaws 6 in left and right, some coincidence of the drive end of two jaws 6, the top of the drive end intersection of two jaws 6 is provided with pin 7, pin 7 is fixed on pedestal 1, pin 7 position is arranged on the mirror shaft of two jaws 6, a spring 4 is connected with between sliding panel 3 and pedestal 1, sliding panel 3 is close to stage clip 5 below the intersection of the drive end of two jaws 6, sliding panel 3 offers the skateboards slot coordinated with pin 7 on two jaw 6 mirror shafts, the free end of stage clip 5 is fixedly connected with the bottom land of skateboards slot.The drive end lower surface of stage clip 5 and two jaws 6 offsets, and sliding panel 3 offers the cavity holding stage clip 5.
During use, gear 2 turns clockwise and drives the tooth bar 31 that engages with it, drive sliding panel 3 upward sliding, sliding panel 3 drives jaw 6 upward sliding, and the drive end of jaw 6 bumps against with pin 7, because pin 7 is fixed on pedestal 1 in the process of sliding, in the process that the pin joint of jaw 6 moves upward, the drive end of jaw 6 rotates around pin joint, and the driven end of jaw 6 then revolves rotating closed in opposite directions, holding workpiece 8; Release process, gear 2 is rotated counterclockwise, the sliding panel 3 engaged with it moves downward, pin 7 is away from the drive end of jaw 6, the driven end of jaw 6 is without thrust, the extension spring now connecting two jaw 6 drive ends will restore to the original state state, pull the drive end opposite direction rotating of jaw 6, now the driven end of jaw 6 then rotates dorsad, be returned to position to be held, unclamp workpiece 8, simultaneously, sliding panel 3 shrinks back original position under gear 2 with the driving of tooth bar 31, and the jaw 6 be hinged on sliding panel 3 also just gets back to original position.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
