Abstract
The invention discloses a cam wheel clamping device in the machinery field. The cam wheel clamping device comprises an engine base, a clamping jaw, long and short ejector rod, two pushing wheels and a push rod, wherein the clamping jaw is hinged with the engine base, the long and short ejector rods are used for clamping a workpiece, the pushing wheels comprise coaxial intermittent gearings and cam wheels for jacking the ejector rod; the engine base is provided with an oil cylinder and the push rod for pushing the oil cylinder, and a rack meshed with the intermittent gearings is arranged on the push rod; the ejector rod is connected with the engine base in a sliding manner, a pin shaft for preventing the ejector rod from rotating is arranged between the engine base and the ejector rod, and passes through a hole which is formed in the ejector rod and used for limiting the horizontal displacement of the ejector rod; a driven end of the long ejector rod is hinged with the clamping jaw; a compressing end of the clamping jaw and the short ejector rod are opposite to each other on the two sides of the workpiece; and a spring is connected between the ejector rod and the pin shaft. The cam wheel clamping device can clamp the workpiece in the horizontal direction, is simple and rapid to operate, and stable in clamping effect.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of cam clamping device.
Background technology
Clamping device is that the workpiece of having good positioning is fixed on the setting element in whole process reliably, and the mechanism that changes of occurrence positions not.When clamping work pieces, do not allow to destroy the location of workpiece, and enough rigidity should be arranged, guarantee necessary clamping force, but should not damage the workpiece machined surface or make workpiece produce distortion, thereby guarantee machining accuracy.Because the outer surface of most of workpiece need to be processed, and for the ease of the processing of lathe to workpiece, need to have the clamping device that clamps from inside workpiece to fix workpiece, because workpiece is various, need to design different clamping devices to different workpieces.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cam clamping device of horizontal direction clamping work pieces.
In order to solve the problems of the technologies described above, the invention provides a kind of cam clamping device, comprise support, promote wheel and catch bar with the hinged jaw of support, the long and short push rod, two that are used for clamping work pieces, promote the cam that wheel comprises coaxial partial gear and jacking push rod; Described support is provided with oil cylinder and by the catch bar of oil cylinder pushing, catch bar is provided with the tooth bar with the partial gear engagement; Described push rod and support are slidingly connected, and are provided with the bearing pin that prevents that push rod from rotating between support and the push rod, and described bearing pin passes the hole of the restriction push rod horizontal displacement on the push rod; The driven end of long push rod is hinged with jaw; The compression end of jaw is relative in the workpiece both sides with short push rod; Be connected with spring between described push rod and the bearing pin.
When carrying out clamping work pieces, extract in-oil cylinder hydraulic oil out, catch bar moves down, because catch bar is provided with the tooth bar with the partial gear engagement, the rack drives partial gear clockwise rotates, partial gear drives coaxial cam and rotates the long and short push rod of jack-up, push rod is under the effect of bearing pin, do not produce relative rotation with support, bearing pin also limits the displacement of push rod, hinged jaw clockwise rotates so that the compression end of jaw relatively moves with short push rod on the long push rod, realizes the clamping to the workpiece horizontal direction.When unclamping workpiece, injection liquid force feed in the oil cylinder, the promotion catch bar moves up, tooth bar promotion partial gear on the catch bar rotates counterclockwise lays down cam to the top lift of push rod, under the effect of spring between push rod and the bearing pin, push rod is retracted, and long push rod retraction drives jaw and rotates counterclockwise, thereby unclamps the clamping to workpiece.The present invention has realized the clamping to the workpiece horizontal direction, and is simple and quick, clamps effect stability.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Embodiment: as shown in Figure 1, the invention provides a kind of cam clamping device, comprise that support 11, two are used for the long and short push rod of clamping work pieces 1 and as the promotion wheel of force application apparatus, promote the cam 6 that wheel comprises coaxial partial gear 7 and jacking push rod 2; The catch bar 9 that described support 11 is provided with oil cylinder 12 and is promoted by oil cylinder 12, catch bar 9 is provided with the tooth bar 8 with partial gear 7 engagements; Described push rod 2 is slidingly connected with support 11, is provided with the bearing pin 4 that prevents that push rod 2 from rotating between support 11 and the push rod 2, and described bearing pin 4 passes the hole 3 of the restriction push rod 2 horizontal frees degree on the push rod 2; The driven end of long push rod is hinged with the middle part jaw 10 hinged with support 11; The compression end of jaw 10 is oppositely arranged with short push rod; 4 of described push rod 2 and bearing pin are connected with spring 5.
When carrying out clamping work pieces 11, extract the hydraulic oil in the oil cylinder 12 out, catch bar 9 moves down, because catch bar 9 is provided with the tooth bar 8 with partial gear 7 engagements, tooth bar 8 drives partial gear 7 and clockwise rotates, it is long that partial gear 7 drives coaxial cam 6 rotation jack-up, short push rod, push rod 2 is under the effect of bearing pin 4, do not produce relative rotation with support 11, bearing pin 4 also limits the displacement of push rod 2, hinged jaw 10 clockwise rotates so that the compression end of jaw 10 relatively moves with short push rod on the long push rod, realizes the clamping to workpiece 11 horizontal directions.When unclamping workpiece 11, to oil cylinder 12 interior injection liquid force feeds, promoting catch bar 9 moves up, tooth bar 8 on the catch bar 9 promotes partial gear 7 and rotates counterclockwise the top lift of laying down 6 pairs of push rods 2 of cam, under the effect of spring 5 between push rod 2 and the bearing pin 4, push rod 2 is retracted, and long push rod retraction drives jaw 10 and rotates counterclockwise, thereby unclamps the clamping to workpiece 11.The present invention has realized the clamping to workpiece 11 horizontal directions, and is simple and quick, clamps effect stability.
Above-described only is preferred embodiment of the present invention, should be understood that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
