Description
Technical field
The utility model belongs to the MACHINERY JOINT field, particularly relates to a kind of connection with spiral shell snapping head.
Background technique
At present, spiral shell snapping head is the vital part in the railway switch conversion equipment erecting device, is used for being connected of erecting device rod member and most advanced and sophisticated iron, makes the straight line of rod member move through this part and is delivered on the most advanced and sophisticated iron.Existing this part is that smith forging or common die forge and form, and lamination very easily occurs, scar, defective such as crackle and profile are coarse, and each size is not accurate, and the processing part allowance is bigger.And project organization is complicated, installs and uses trouble, connects insecurely, has technical problems such as potential safety hazard.
Summary of the invention
The utility model provides a kind of connection with spiral shell snapping head for solving the technical problem that exists in the known technology.
It is mellow and full that the purpose of the utility model provides a kind of smooth surface, and shape is accurately complete, has simple in structurely, with low cost, and the connection of characteristics such as assembling is compact, and it is convenient to install, and is connected firmly, economical and practical is with spiral shell snapping head.
The utility model connects the technological scheme of being taked with spiral shell snapping head:
A kind of connection is characterized in spiral shell snapping head: spiral shell snapping head has two to connect the termination, and one connects the termination is worm structure, and another connects the termination is the bolt-type structure.
The utility model connects can also adopt following technological scheme with spiral shell snapping head:
Described connection is characterized in spiral shell snapping head: it is nut type that worm structure connects the termination, and endoporus has screw thread, and appearance has the corner angle plane.
Described connection is characterized in spiral shell snapping head: appearance has 6 corner angle planes.
Described connection is characterized in spiral shell snapping head: it is horseshoe-shaped structure that the bolt-type structure connects the termination, and the termination is provided with pin-and-hole.
Described connection is characterized in spiral shell snapping head: horseshoe-shaped structure connects the outside, termination and is arc surface, and there is circular pin hole at the arc surface middle part.
Advantage and the good effect that the utlity model has are:
Connect with spiral shell snapping head owing to adopted the utility model brand-new technology scheme; Compared with prior art; The utility model adopts the mould precision forging, and through 4 shapings, forges to accomplish back other positions and shape except that part end, hole and helical thread portion and all need not to process; Smooth surface is mellow and full, and shape is accurately complete.The utlity model has simple in structurely, with low cost, economical and practical, assembling is compact, is connected firmly, and advantages such as convenient are installed.
Description of drawings
Fig. 1 connects with spiral shell snapping header structure schematic representation;
Fig. 2 is Fig. 1 plan structure schematic representation;
Fig. 3 structural representation that is linked and packed when being the utility model practical application.
Among the figure, 1-connects the termination, 2-pin-and-hole, 3-spiral shell snapping head, 4-rib, 5-screw thread, 6-latch, 7-nut, 8-tongue iron, 9-pull bar.
Embodiment
For further understanding model utility content, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
With reference to accompanying drawing 1, Fig. 2 and Fig. 3.
A kind of connection has two to connect the termination with spiral shell snapping head 3, and one connects the termination is worm structure, and another connects termination bolt-type structure.
It is nut type that worm structure connects the termination, and endoporus has screw thread 5, and appearance has 6 corner angle planes.It is horseshoe-shaped structure that the bolt-type structure connects the termination; It is arc surface that horseshoe-shaped structure connects 1 outside, termination, and there is circular pin hole 2 at the arc surface middle part.
Embodiment 2
A kind of application that connects with spiral shell snapping head.Connection shown in the embodiment 1 has two to connect the termination with spiral shell snapping head 3, and one connects the termination is worm structure, and another connects termination bolt-type structure.Worm structure connects the inner hole thread 5 of termination, connects tongue iron 8 through nut 7 screw rods, and the opposite side of tongue iron 8 has cylinder lever connecting rod 9.
This connection with spiral shell snapping head part when practicing; Can be used as the vital part in the railway switch conversion equipment erecting device; Can be widely used in being connected of rod member and most advanced and sophisticated iron in the erecting device; As shown in Figure 3: (accompanying drawing 3 front rod of a point erection drawings) make the straight line of rod member move through this part and are delivered on the most advanced and sophisticated iron.
Connecting with spiral shell snapping head is by Common Straight Carbon Steel Q235A forging molding; Adopt the mould precision forging and through 4 shapings; Forge to accomplish back other positions and shape except that part end, hole and helical thread portion and all need not to process, smooth surface is mellow and full, and shape is accurately complete.
