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 location locking mechanism, belong to the frock jig.
Technical background
Heat exchanger often will weld the connector of some band waist-shaped holes in manufacturing process, hole location is had relatively high expectations, and relatively is difficult to the location, causes dimension overproof.In the heat exchanger manufacture process, owing to need the welding accessory, make location configuration occasion by hand, the accurate positioning degree is lower, and speed is slow, inefficiency.So, need a kind of special tool locating structure to guarantee accessory accurate location in welding process.
Summary of the invention
The technical problem that the present invention will solve is in the heat exchanger manufacture process, owing to need the welding accessory, makes location configuration occasion by hand, and the accurate positioning degree is lower, and speed is slow, inefficiency.
For solving above technical problem, technical scheme provided by the invention is following: a kind of mounting hole workpiece location locking mechanism, and workpiece has mounting hole, and said retaining mechanism comprises Connection Block, expansion link, spring and screw;
The both sides of Connection Block have fixing hole; The centre has the horizontal center hole of placing spring and expansion link; Connection Block top vertical-horizontal central hole 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 the lathe through the both sides fixing hole;
Expansion link is a T shape bar, cooperates with spring, is arranged on a side of Connection Block; Be assemblied in the Connection Block central hole; Expansion link compacting spring and Connection Block form relative motion, and Connection Block top latch has the effect that stops expansion link to move, and expansion link has the horizontal groove that cooperates the latch braking;
Said workpiece is fixed in the opposite side of Connection Block through screw, and workpiece is assemblied on the expansion link that passes the Connection Block centre bore through mounting hole, and closely cooperates, and screw connects expansion link fixes workpiece.
Further, said expansion link comprises that handle, cross section are that the waist shape bar of waist shape is with it is connected the screw of effect to the two.
Further, the two ends of said handle have the hole, and an end is used for fixing waist shape bar, and the other end is used to place screw, and this screw connects handle and waist shape bar.
Further, be provided with C shape cushion block between the screw of said fixation workpiece and the workpiece.
Further, the opening of said C shape cushion block is towards a side.
This mounting hole workpiece location locking mechanism that the present invention relates to, driving handle is enclosed within workpiece on the waist shape bar; Release handle utilizes spring to make the automatic workpiece pressing of C shape piece, accurately locatees.
Description of drawings
Fig. 1 is the front view of mounting hole workpiece location locking mechanism of the present invention;
Fig. 2 is a left view;
Fig. 3 is a sectional view;
Fig. 4 is the Workpiece structure sketch map;
The 1-screw; 2-C shape cushion block; The 3-workpiece; The 4-Connection Block; The 5-screw; The 6-spring; The 7-expansion link; 71-waist shape bar; The 72-screw; The 73-handle; The 31-pin-and-hole.
The specific embodiment
As shown in Figure 1, said retaining mechanism comprises Connection Block 4, expansion link 7, spring 6 and screw 1 and screw 5;
Expansion link 7 comprises that handle 73, cross section are that the waist shape bar 71 of waist shape is with it is connected the screw 72 of effect to the two.
The two ends of handle 73 have the hole, and an end is used for fixing waist shape bar 71, and the other end is used to place screw 72, and this screw 72 connects handle 73 and waist shape bar 71.
Be provided with C shape cushion block 2 between the screw of fixation workpiece 3 and the workpiece 3.
The opening of C shape cushion block 2 is towards a side.
A kind of mounting hole workpiece location locking mechanism provided by the invention, simple in structure, can be effectively with the workpiece location that has mounting hole that is difficult to locate; And method is simple to operation, and the top effect of putting through spring only needs Connection Block is fixed; And control the precision of its manufacturing; And assembly precision, guarantee on the Connection Block and the combine closely perpendicularity of face of workpiece, can guarantee the workpiece location precisely.The design of waist shape bar simultaneously, waist shape 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, what make workpiece and Connection Block and waist shape bar combines closelyr, all the more guarantees the positioning accuracy of workpiece.
The specific embodiment of the present invention does not constitute the restriction to the application's scope; Within every spirit in the present invention design and the principle, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within protection scope of the present invention.
