Abstract
The invention provides a positioning locking mechanism for a workpiece with a kidney-shaped hole. The workpiece is provided with the kidney-shaped hole; a locking mechanism comprises a connecting seat, a telescopic rod, a spring and screws; fixing holes are arranged on two sides of the connecting seat, a horizontal center hole for placing the spring and the telescopic rod is arranged in the middle of the connecting seat, a threaded hole is arranged on the top of the connecting seat and is perpendicular to the horizontal center hole, the screw for braking is arranged in the threaded hole, and the connecting seat is fixed onto a machine tool by the fixing holes on the two sides of the connecting seat; and the telescopic rod is T-shaped, is matched with the spring, is arranged on one side of the connecting seat, is assembled in the center hole of the connecting seat and compresses the spring to move relative to the connecting seat, a bolt used for stopping the telescopic rod against moving is arranged on the top of the connecting seat, and the telescopic rod is provided with a horizontal groove matched with the bolt for realizing the braking effect. The positioning locking mechanism for the workpiece with the kidney-shaped hole has the advantages that when a handle is pushed, the workpiece is sleeved on a kidney-shaped rod; and when the handle is released, the spring drives a C-shaped block to automatically compress the workpiece, and the workpiece is accurately positioned.
Description
Technical field
The present invention relates to a kind of mounting hole Workpiece fixing retaining mechanism, belong to tooling fixture.
Technical background
Heat exchanger is in manufacturing process, and often will weld the connector of some band waist-shaped holes, hole location requires higher, compares and is difficult to location, cause dimension overproof.In manufacture of heat exchangers, due to needs welding accessory, make bond-allocating occasion by hand, positioning accurate accuracy is lower, and speed is slow, inefficiency.So, need a kind of special tool locating structure to ensure that accessory is accurately located in welding process.
Summary of the invention
The technical problem to be solved in the present invention is in manufacture of heat exchangers, and due to needs welding accessory, make bond-allocating occasion by hand, positioning accurate accuracy is lower, and speed is slow, inefficiency.
For solving above technical problem, technical scheme provided by the invention is as follows: a kind of mounting hole Workpiece fixing retaining mechanism, and workpiece has mounting hole, and described retaining mechanism comprises Connection Block, expansion link, spring and screw;
The both sides of Connection Block have fixing hole, centre has the horizontal centre hole of placing spring and expansion link, Connection Block plan vertical horizontal centre hole place is provided with screwed hole, and this screwed hole place has been provided with the screw of braking action, and Connection Block is fixed on lathe by both sides fixing hole;
Expansion link is T-shaped bar, coordinates with spring, is arranged on the side of Connection Block, be assemblied in Connection Block central hole, expansion link compacting spring and Connection Block form relative motion, and Connection Block top latch has the effect stoping expansion link movement, and expansion link has the horizontal groove coordinating latch braking;
Described workpiece is fixed on the opposite side of Connection Block by screw, and workpiece is assemblied on the expansion link through Connection Block centre bore by mounting hole, and closely cooperates, and workpiece is fixed by screw connection expansion link.
Further, the kidney-shaped bar that described expansion link comprises handle, cross section is kidney-shaped and the screw to the two its connection function.
Further, the two ends of described handle have hole, and one end is used for fixing kidney-shaped bar, the other end for placing screw, this screw connecting handle and kidney-shaped bar.
Further, C shape cushion block is provided with between the screw of described fixation workpiece and workpiece.
Further, the opening of described C shape cushion block is towards side.
This mounting hole Workpiece fixing retaining mechanism that the present invention relates to, driving handle, is enclosed within kidney-shaped bar by workpiece; Release handle, utilizes spring to make C shape block automatic impaction workpiece, accurately locates.

Detailed description of the invention
As shown in Figure 1, described retaining mechanism comprises Connection Block 4, expansion link 7, spring 6 and screw 1 and screw 5;
The kidney-shaped bar 71 that expansion link 7 comprises handle 73, cross section is kidney-shaped and the screw 72 to the two its connection function.
The two ends of handle 73 have hole, and one end is used for fixing kidney-shaped bar 71, the other end for placing screw 72, this screw 72 connecting handle 73 and kidney-shaped bar 71.
C shape cushion block 2 is provided with between the screw of fixation workpiece 3 and workpiece 3.
The opening of C shape cushion block 2 is towards side.
A kind of mounting hole Workpiece fixing retaining mechanism provided by the invention, structure is simple, effectively can will be difficult to the Workpiece fixing with mounting hole of locating, and method is simple to operation, by the top set effect of spring, only Connection Block need be fixed, and control its precision manufactured, and assembly precision, ensure the perpendicularity in face that Connection Block is combined closely with workpiece, the accurate of Workpiece fixing can be ensured.The design of kidney-shaped bar simultaneously, kidney-shaped bar inserts the mounting hole of workpiece, and the two is combined closely, and is the key of location.Moreover the use of spring and C shape cushion block, makes the combination of workpiece and Connection Block and kidney-shaped bar tightr, all the more ensures the positioning precision of workpiece.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
