Description
Technical Field
The utility model relates to a hardware clamp.
Background
The clamp is a technological device used for quickly fastening a workpiece during processing so as to keep a machine tool, a cutter and the workpiece at correct relative positions. That is to say, the tool clamp is an indispensable part for machining, and under the drive that the machine tool technology develops towards high speed, high efficiency, precision, composite, intelligent and environmental protection, the clamp technology is developing towards high precision, high efficiency, module, combination, universality and economy.
The fixture is very high in use for electronic manufacturers, and in order to improve production efficiency and product quality in production, a tool fixture is commonly used for performing function test or auxiliary assembly (fixed appearance, height and the like can be assembled) at the middle section and the rear section of production. The actual use in an electronics manufacturing plant is very widespread, and is not possible because it is off-the-shelf and therefore only unexpected.
Patent application number is 2013107414681 supplementary anchor clamps of circuit board, including horizontal, straight rail, still include swing joint left and right pole setting on the horizontal rail, left and right pole setting is fixed respectively on left and right straight rail, still connects flexible rotation regulating block subassembly and retaining member respectively in the left and right pole setting. Two clamping blocks on the telescopic rotating and rotating adjusting block assembly can rotate 360 degrees in an all-round mode, a user can carry out multi-angle adjusting operation as required, and the requirement of working or operating habits is met to achieve the purpose of improving efficiency. The utility model has complex components and overlarge size, and is not suitable for clamping small-specification or special-shaped circuit board workpieces.
The cantilever mounting clamp of patent application No. 2014800599232 has: a mounting table (21a) on the upper surface of which the cantilever (1) is placed; a pressing member (21b) for pressing the cantilever (1) against the upper surface of the mounting table (21 a); and a push-up mechanism (21c) for moving the pressing member (21b) upward from the upper surface of the mounting table (21a), the cantilever mounting jig (100) comprising: and a slide table (120) having a slide surface (121) for sliding the boom (1) toward the mount table (21 a). This patent cantilever is furnished with the slip table, but the slip clearance makes the centre gripping stability of anchor clamps relatively poor.
Disclosure of Invention
Utility model purpose:
the elastic probe clamp has uniform loading pressure and is not easy to damage a workpiece.
The technical scheme is as follows:
the elastic probe card clamp is provided with a support rod and a pressing rod perpendicular to the support rod. One end of the supporting rod is provided with a shaft hole which is convenient for horizontal arrangement, the middle of the supporting rod is provided with a through hole which is vertically communicated, and the other end of the supporting rod is downwards connected with a pressing rod.
The shaft hole can penetrate through the fixed shaft (in clearance fit), and the supporting rod can drive the pressing rod to rotate around the fixed shaft; the through hole can pass through a screw which can be in threaded connection with a foundation below.
The bracing piece is the metal material with the press bar main part, and the intensity rigidity is all great, is difficult for producing deformation.
When the support rod rotates downward, the pressing rod gradually rotates inward, and a sharp pressure is easily generated when the left corner first contacts the pressed workpiece.
Moreover, because the contact area at the moment of contact is small, the pressure is large, and the workpiece is easily damaged when the pressing rod is made of all metal (particularly, the workpiece has a greater risk of damage to a probe card made of a circuit board material).
The lower end of the pressing rod is an inclined plane (the height of the left side is greater than that of the right side), and a rubber gasket with a right trapezoid cross section is bonded on the lower end of the pressing rod; the rubber gasket increases the elasticity during pressing, so that the pressed workpiece is not easy to damage. When the pressing rod is used, a workpiece is placed below the pressing rod and is directly contacted and pressed by the rubber gasket. The screw is drilled into the foundation for fixation, and the nut can adjust the depth of the screw entering the foundation and the position of the supporting rod.
The corner at the other end of the supporting rod is provided with an oblique chamfer, and a rubber protection sheet with a right-angled triangle section is bonded on the chamfer. Therefore, the upper surface of the supporting rod is kept horizontal, and other objects can be conveniently placed above the supporting rod when the supporting rod is pressed; meanwhile, the corners have flexible elasticity and cannot scrape workpieces (especially workpieces with higher sides).
Or the lower end of the pressing rod is an inclined plane, the height of the left side of the inclined plane is greater than that of the right side of the inclined plane, a rubber gasket with a right-angled triangle-shaped section is bonded on the inclined plane, and the bottom area of the rubber gasket is smaller than the vertical downward projection area of the pressing rod. When the elastic rubber presses the workpiece, a small part of the lower end of the rigid pressing rod presses the workpiece, and the workpiece is clamped more firmly by pressing.
Has the advantages that:
the utility model has simple structure, convenient use and firm pressing workpiece, and the pressing force can be adjusted by the number of rotation turns of the screw. The pressed contact surface has flexibility and is not easy to damage the upper surface of the workpiece; the upper side close to the workpiece has flexibility, the side or the upper side of the workpiece is not easy to be damaged, and the safety is high.
The clamping device is simple in structure, few in parts, tight in matching of the fixed shaft and the screw to the supporting rod, low in degree of freedom and suitable for accurately positioning and clamping workpieces. The clamping of the large-scale electronic circuit board can adopt the cooperation of a plurality of clamps, and the installation and the disassembly are convenient and fast.
