Abstract
The utility model discloses an ejector rod arm for fixing catenary rings. The ejector rod arm comprises a working head (4) and a connecting arm (1). A protruded block (3) is arranged at one end of the working head (4), and the protruded block is matched with a groove (2) which is arranged at one end of the connecting arm (1). The working head (4) is fixedly connected with the connecting arm (1). When the working head or the connecting arm is broken, the working head can be changed by only separating two parts. The working head is provided with bearing pads, so that cracking and wearing in openings can be avoided. Accordingly, the cost can be reduced and the efficiency can be improved in manufacturing.
Description
Technical field
The utility model relates to the push rod arm of fixed linkage in chain production process.
Background technology
During chain is produced, when after bending, chain link must be welded, at this moment just need two push rod arm fixed linkage, existing push rod arm is as a whole, in work, the opening part of push rod arm easily weares and teares, ftractures, whole piece armed lever is easily distortion also, and this just causes misplacing in chain link welding process, thereby affects product quality, and each replacing need, by whole push rod arm replacing, improve production cost.
Utility model content
The purpose of this utility model is to provide a kind of and needs to change damage parts, without the push rod arm of integral replacing.
The technical solution adopted in the utility model is: the push rod arm for fixed linkage, comprise working head and linking arm, and described working head one end is provided with projection, and the groove of projection and linking arm one end is suitable, and described working head and linking arm are connected.
As further improvement of the utility model, working head and linking arm are soldered.
As further improvement of the utility model, the working end opening part of working head is provided with cushion block, and cushion block is connected with working head screw.
The beneficial effects of the utility model are: when working head damages, only needing separately two parts, change moving head, is also like this when in like manner linking arm damages; On working head, be provided with pad, can effectively prevent opening part cracking and wearing and tearing; In production, use this push rod arm can reduce cost, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 linking arm, 2 grooves, 3 projections, 4 working heads, 5 cushion blocks.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment is elaborated.
As shown in Figure 1, the present embodiment comprises working head 4 and linking arm 1, and described working head 4 one end are provided with projection 3, and projection 3 is suitable with the groove 2 of linking arm 1 one end, and described working head 4 is connected with linking arm 1, and working head 4 is soldered with linking arm 1.
In order to prevent working head 4 crackings, the working end opening part of working head 4 is provided with cushion block 5, and cushion block 5 is connected with working head 4 screws.
When working head damages, only need separately two parts, change moving head, when in like manner linking arm damages, be also like this; On working head, be provided with pad, can effectively prevent opening part cracking and wearing and tearing; In production, use this push rod arm can reduce cost, improve work efficiency.
Claims (3)
