Abstract

The utility model relates to a wedge-shaped welding fixture device which is characterized by comprising a bottom fixing block which is fixed on a rack and an end fixing block which is arranged above the rack, a wedge-shaped fixture body which can move horizontally is arranged between the bottom fixing block and the end fixing block, the lower surface of the end fixing block is a slope 2 which is matched with a slope 1 of the wedge-shaped fixture body, and the upper surface of the bottom fixing block is a mounting surface used for placing a welding workpiece to be welded 1 and a welding workpiece to be welded 2. When welding is in process, one side end faces of the welding workpiece to be welded 1 and the welding workpiece to be welded 2 closely fit the mounting surface, and the other side end faces of the welding workpiece to be welded 1 and the welding workpiece to be welded 2 closely fit the wedge-shaped fixture body. One end of a screw rod is connected with the wedge-shaped fixture body and an operation part easy for operation personnel to hold is arranged at the other end of the screw rod. The wedge-shaped welding fixture device is suitable for small workshop production and being used in laboratory environment, and is small and exquisite in structure, convenient to use, low in cost and reliable in clamping.

Description

A kind of wedge bonding grip device
Technical field
The utility model relates to a kind of grip device, relates in particular to a kind of wedge bonding grip device, is used for realizing all-position welding.
Background technology
In actual production or under the laboratory condition, usually need two block of material downhand weldings, even with sample position docking according to the rules.In welding process, usually need welding personnel or crouching or kneel or the posture of lying test weld on the ground, it is very inconvenient to operate, and welding quality is difficult to guarantee.At present, the machine that the is welded and fixed complex structure of selling on the market, the cost cost is high, is not suitable between laboratory environment and dolly and produces.For this reason, need to be a kind of simple in structure, handled easily, cost is low, the weld fixture apparatus of reliable clamping.
Summary of the invention
The purpose of this utility model provides and a kind ofly is applicable between dolly to produce and the grip device that is used for downhand welding of laboratory environment.
In order to achieve the above object, the technical solution of the utility model has provided a kind of wedge bonding grip device, it is characterized in that: comprise the bottom fixed block that is consolidated on the frame and the end fixed block of the side of being located thereon, it is concrete to be provided with the wedge grip that can move horizontally between bottom fixed block and end fixed block, the inclined-plane two of the lower surface of end fixed block for matching with the concrete inclined-plane one of wedge grip, the upper surface of bottom fixed block is for being used for placing the installed surface of workpiece one to be welded and workpiece to be welded two, during welding, one side end face and this installed surface of workpiece one to be welded and workpiece to be welded two fit tightly, its opposite side end face and wedge grip specifically fit tightly, it is concrete that one end of screw mandrel connects wedge grip, is provided with the operating portion that the convenient operation personnel grip at its other end.
Preferably, the lower surface of described end fixed block, upper surface and the concrete up and down both side surface of described wedge grip of described bottom fixed block are coarse.
The grip device that the utility model provides be applicable between dolly to produce and laboratory environment in, its structure is small and exquisite, and is easy to use, with low cost, reliable clamping.
Description of drawings
A kind of wedge bonding that Fig. 1 provides for the utility model structural representation of grip device.
The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, a kind of wedge bonding grip device that the utility model provides, comprise the bottom fixed block 1 that is consolidated on the frame and the end fixed block 8 of the side of being located thereon, between bottom fixed block 1 and end fixed block 8, be provided with the wedge grip that can move horizontally concrete 4, the inclined-plane two of the lower surface of end fixed block 8 for matching with the inclined-plane one of wedge grip concrete 4, it is identical with the angle α between inclined-plane two and the horizontal plane with angle α between the horizontal plane to be inclined-plane one, the upper surface of bottom fixed block 1 is for being used for placing the installed surface of workpiece 1 to be welded and workpiece to be welded 23, during welding, one side end face and this installed surface of workpiece 1 to be welded and workpiece to be welded 23 fit tightly, its opposite side end face and wedge grip concrete 4 fit tightly, it is concrete 4 that one end of screw mandrel 5 connects wedge grip, and its other end passes leading screw on the frame and supports the operating portions 7 that grip with the convenient operation personnel after 6 and link to each other.
The up and down both side surface of the upper surface of the lower surface of end fixed block 8, bottom fixed block 1 and wedge grip concrete 4 is coarse.
During grip device work, leading screw 5 is retreated to suitable position, workpiece 1 to be welded and workpiece to be welded 23 are placed between bottom fixed block 1 and the end fixed block 8 by welding the position that needs, turn operating portion 7, then the precession of leading screw 5 control clamp body 4 advances, height according to institute's welding material is different, and the height that clamp body 4 sticks between the fixed block is different.
If it is N that fixed block 8 upper surfaces in end put on the normal pressure of clamp body 4, the skin-friction coefficient of contact-making surface is f, then according to Newton's law, the horizontal force that end fixed block 8 is applied to wedge grip concrete 4 is T=Nsin α, vertically power is T '=Ncos α, then to be applied to the frictional force of wedge grip concrete 4 be fNcos α to soldered material, when fNcos α>Nsin α, self-locking occurs in wedge grip concrete 4, can guarantee reliable clamping, the skin-friction coefficient that therefore only needs to change contact-making surface can change the clamping degree.
