Abstract

The utility model provides a be applied to welding jig's unsteady hold-down mechanism, including compressing tightly arm, compact heap, be equipped with 2 mounting holes along length direction on the compressing tightly arm, 2 fixing bolt pass compress tightly the arm mounting hole in below and compact heap threaded connection, install compression spring between compact heap and the compact heap. The utility model discloses set up compression spring between compact heap and compress tightly the arm, make the compact heap have a function of kick-backing, when compressing tightly the arm and pushing down, compression spring contracts to certain extent and forms the packing force and can not make the compact heap compress tightly with the part hard contact, has certain buffer room, does not have the indentation on the surface of part, does not harm the surface of part.

Description

Floating pressing mechanism applied to welding fixture

Technical Field

The utility model belongs to spare part machining field relates to the hold-down mechanism that floats of being applied to welding jig.

Background

When the welding fixture is used, when a part with a pressing position on the outer surface is clamped and positioned, an indentation is formed on the part occasionally due to inaccurate clamping and positioning of the pressing mechanism (the pressing plate device), an operator is required to grind the indentation part, the part is damaged to a certain extent even if the grinding is carried out, the workload is increased invisibly, the process beat is delayed, and the working efficiency is low.

Disclosure of Invention

In order to overcome among the prior art hold-down mechanism because press from both sides the inaccurate and cause the technical problem that compresses tightly the position and have the indentation on the surface of part, the utility model provides a be applied to welding jig's unsteady hold-down mechanism.

For solving the technical problem, the utility model discloses a following technical scheme: be applied to welding jig's hold-down mechanism that floats, including compress tightly arm, compact heap, its characterized in that: the last 2 mounting holes that are equipped with of compression arm along length direction, 2 fixing bolt pass the compression arm mounting hole and be in below and compact heap threaded connection, install compression spring between compact heap and compression arm.

The technical scheme is further limited as follows: the number of the compression springs is 2, the compression springs are respectively sleeved on the shaft necks of the fixing bolts, the upper ends of the compression springs are in contact with the lower end faces of the pressing arms, and the lower ends of the compression springs are in contact with the upper end faces of the pressing blocks; the structure is simple and easy to implement.

The utility model has the advantages that: the utility model discloses set up compression spring between compact heap and compress tightly the arm, make the compact heap have a function of kick-backing, when compressing tightly the arm and pushing down, compression spring contracts to certain extent and forms the packing force and can not make the compact heap compress tightly with the part hard contact, has certain buffer room, does not have the indentation on the surface of part, does not harm the surface of part.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Shown in the figure: 1. a pressing arm; 2. a compression block; 3. a compression spring; 4. fixing the bolt; 4-1 and an external thread part.

Detailed Description

The invention is further described below with reference to the accompanying drawings: as shown in fig. 1, the floating pressing mechanism applied to the welding fixture comprises a pressing arm 1 and a pressing block 2, wherein 2 mounting holes are formed in the pressing arm 1 along the length direction, 2 fixing bolts 4 penetrate through the pressing arm mounting holes and are in threaded connection with the pressing block 2 at the lower part (in threaded connection with the pressing block 2 through external thread parts 4-1 of the fixing bolts 4), and a compression spring is installed between the pressing block and the pressing arm.

As shown in fig. 1, 2 compression springs 3 are respectively sleeved on the shaft necks of the fixing bolts, the upper ends of the compression springs 3 are in contact with the lower end faces of the pressing arms 1, and the lower ends of the compression springs 3 are in contact with the upper end faces of the pressing blocks 2; the structure is simple and easy to implement.

The utility model can overcome the technical problem that the pressing position of the pressing mechanism has indentation on the outer surface of the part due to the inaccurate clamping and positioning of the pressing mechanism in the prior art; however, the inner surface of the part is not recommended to be used when being pressed, and due to the elastic function, the problems of insufficient pressing force and the like can be caused, so that the welding precision does not reach the standard.

For those skilled in the art, simple combination, equivalent replacement, and further improvement without departing from the technical concept or essential features of the present invention should be included in the protection scope of the present invention.

Claims
