Abstract
The utility model provides a locating and locking mechanism for a waist-shaped hole workpiece. The workpiece is provided with a waist-shaped hole. A locking mechanism comprises a connection seat, a telescopic pole, a spring and a bolt, wherein fixing holes are formed at two sides of the connection seat, the middle of the connection seat is provided with a horizontal central hole used for placing the spring and the telescopic pole, a screw hole is formed at the position of the top of the connection seat perpendicular to the horizontal central hole, the bolt with a braking function is arranged at the position of the screw hole, the connection seat is fixed on a machine tool through the fixing holes at two sides, the telescopic pole is a T-shaped pole, is matched with the spring, is arranged at one side of the connection seat and is assembled at the position of the central hole of the connection seat, the telescopic pole suppresses the spring to make movement relative to the connection seat, a plug pin at the top of the connection seat prevents the telescopic pole from moving, and the telescopic pole is provided with a horizontal groove which is matched with the braking of the plug pin. According to the locating and locking mechanism for the waist-shaped hole workpiece, when the handle is pushed, the workpiece is sleeved on a waist-shaped pole, and when the handle is loosened, a C-shaped cushion block is enabled to tightly compress the workpiece automatically by means of the spring, and accurate location is carried out.
Description
Technical field
The utility model relates to a kind of mounting hole workpiece location locking mechanism, belongs to tooling fixture.
Background technology
Heat exchanger often will weld some with the connector of waist-shaped hole in manufacturing process, hole location is had relatively high expectations, and relatively is difficult to the location, causes dimension overproof.In the heat exchanger process, owing to needing the welding accessory, make by hand bond-allocating occasion, the positioning accurate accuracy is lower, and speed is slow, inefficiency.So, need a kind of special tool locating structure to guarantee accessory accurate location in welding process.
The utility model content
The technical problems to be solved in the utility model is in the heat exchanger process, owing to needing the welding accessory, makes by hand bond-allocating occasion, and the positioning accurate accuracy is lower, and speed is slow, inefficiency.
For solving above technical problem, the technical scheme that the utility model provides is as follows: a kind of mounting hole workpiece location locking 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, the centre has the horizontal centre bore 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 by the both sides fixing hole;
Expansion link is 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;
Described workpiece is fixed in the opposite side of Connection Block by screw, workpiece is assemblied on the expansion link that passes the Connection Block centre bore by mounting hole, and closely cooperates, and the screw connection expansion link is fixed workpiece.
Further, described expansion link comprises that handle, cross section are the kidney-shaped bar of kidney-shaped and the two is played the screw of connection function.
Further, the two ends of described handle have the hole, and an end is used for fixedly kidney-shaped bar, and the other end is used for placing screw, this screw connecting handle and kidney-shaped bar.
Further, be provided with C shape cushion block between the screw of described fixation workpiece and the workpiece.
Further, the opening of described C shape cushion block is towards a side.
This mounting hole workpiece location locking mechanism that the utility model relates to, driving handle is enclosed within workpiece on the kidney-shaped bar; Release handle utilizes spring to make C shape piece automatic impaction workpiece, accurately locates.
Description of drawings
Fig. 1 is the front view of the utility model mounting hole workpiece location locking mechanism;
Fig. 2 is left view;
Fig. 3 is sectional view;
Fig. 4 is the Workpiece structure schematic diagram;
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-kidney-shaped bar; The 72-screw; The 73-handle; The 31-pin-and-hole.
The specific embodiment
As shown in Figure 1, described retaining mechanism comprises Connection Block 4, expansion link 7, spring 6 and screw 1 and screw 5;
The two ends of handle 73 have the hole, and an end is used for fixedly kidney-shaped bar 71, and the other end is used for placing screw 72, these screw 72 connecting handles 73 and kidney-shaped 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 that the utility model provides, simple in structure, can be effectively with the workpiece location with mounting hole that is difficult to locate, and method is simple to operation, by the top set effect of 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 simultaneously design of kidney-shaped bar, the 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 guarantees the positioning accuracy of workpiece.
The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
