Abstract
The utility model discloses a clamping tool for preventing a grinding product from dropping, relating to a clamping tool for mechanical processing. The clamping tool comprises a fixed plate and an air cylinder, wherein the air cylinder is arranged at the top of the fixed plate, and a piston rod of the air cylinder passes through the fixed plate and extends to the bottom of the fixed plate. The clamping tool is characterized by comprising an extension rod, a spring, a movable rod and a bearing, wherein the bottom of the piston rod is connected with the top of the extension rod, the inner part of the extension rod is hollow and provided with the spring, the bottom of the spring is connected with the movable rod in the extension rod, and the bottom of the movable rod is provided with the bearing which is matched with the processing surface of the grinding product and can freely rotate. The clamping tool solves the problems that the product is easy to drop in a grinding process, and meanwhile, as a manual supporting mode, operators have large labor intensity, and the product has low processing quality. The utility model provides a special clamping tool with simple structure and convenient use, which can effectively fix and press the grinding product.
Description
Technical field
The utility model relates to a kind of machining clamping fixture, particularly relates to a kind of special-purpose clamping fixture that the process of lapping product clamps that is used for.
Background technology
The milling apparatus of prior art is placed with required abrasive product on the supporting plate between emery wheel and the guide wheel, come the machined surface of abrasive product by the rotation of emery wheel and guide wheel, produces finished product.But in process of lapping, the total that does not often need abrasive product, only need to grind some of working positions, when grinding like this, the product working position can diminish because constantly grind, lighten, product can be to unprocessed lopsidedness, drops from supporting plate and can't continue attrition process.When solving the product attrition process, the problem that drops easily adopts artificial support mode more, promptly holds the unprocessed side of attrition process product by operating personnel's hand, comes equilibrium product, makes it be unlikely to drop at present.But adopt this kind method, have following shortcoming: 1, in high speed attrition process process, operating personnel's hand shake easily can have a strong impact on the quality that product is processed, and causes the generation of waste product.2, strengthen labor intensity of operating personnel, influenced operating efficiency, increased the human cost of enterprise simultaneously.3, in the course of the work, utilize manually and help, cause the accident easily, have bigger potential safety hazard.
The utility model content
In order to solve in the product process of lapping, product drops easily, utilizes artificial support mode simultaneously, labor intensity of operating staff is big, the problem that product processing quality is low, and it is a kind of simple in structure that the utility model provides, easy to use, can effectively fixedly clamp the special-purpose clamping fixture of abrasive product.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of clamping fixture that prevents that abrasive product from dropping, comprise fixed head, cylinder, described cylinder is arranged at the top of fixed head, the piston rod of cylinder passes fixed head, reach the bottom of fixed head, it is characterized in that: also comprise extension rod, spring, motion bar, bearing, described piston rod bottom is connected with the extension rod top, the extension rod inner hollow is provided with spring, the bottom of spring is connected with the motion bar that stretches into extension rod inside, is provided with the bearing that matches and can freely rotate with the abrasive product machined surface in the bottom of motion bar.
The beneficial effects of the utility model are:
It is a kind of simple in structure that the utility model provides, easy to use, can effectively push down abrasive product, the utility model utilizes piston rod take off and landing strip dynamic bearing once to compress, in process of lapping, the attrition process position of product constantly dwindles, and stage clip can carry out secondary compression by continuous generation deformation band dynamic bearing like this, make bearing all the time with the product working position, be in impaction state preferably.Adopt this kind compressing structure, machining accuracy is higher, has improved the crudy of product, has saved human cost, has reduced the danger that accident takes place.
Description of drawings
Fig. 1 is the utility model Facad structure schematic diagram;
Fig. 2 is the utility model side structure schematic diagram.
It specifically is embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, a kind of clamping fixture that prevents that abrasive product from dropping, comprise fixed head 1, cylinder 2, extension rod 4, spring 5, motion bar 6, bearing 7, cylinder 2 is arranged at the top of fixed head 1, the piston rod 3 of cylinder 2 passes fixed head 1, reach the bottom of fixed head 1, piston rod 3 bottoms are connected with extension rod 4 tops, extension rod 4 inner hollow are provided with spring 5, the bottom of spring 5 is connected with the motion bar 6 that stretches into extension rod 4 inside, be provided with the bearing 7 that matches with abrasive product 8 working positions 9 in the bottom of motion bar 6, bearing 7 rotates synchronously with the working position 9 of product 8, remains impaction state.
Required converted products 8 is positioned on the supporting plate 11, supporting plate 11 is arranged between emery wheel 12 and the guide wheel 13, during attrition process, emery wheel 12 maintains static, guide wheel 13 moves to emery wheel 12, described guide wheel 13 and emery wheel 12 rolling surfaces carry out attrition process over against the working position 9 of product 8, and that the non-working position 10 of product 8 is positioned at rear side is unaffected.Cylinder 2 control piston bars 3 on the fixed head 1 move down, and finally drive the purpose that bearing 7 realizes compressing product 8 working positions 9.In process of lapping, working position 9 outer rims of product 8 can constantly diminish simultaneously, and at this moment the deformation that moves down by spring 5 is finely tuned, and makes bearing 7 continue to compress the working position 9 of product 8.
More than show, described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
