Abstract
Away from clamping device in a kind of rolling stock draw beam, the clamping device is made of trapezoidal screw, swivel nut and snap-gauge, two swivel nuts are symmetrical arranged in trapezoidal screw two sides, trapezoidal screw and swivel nut are attached by screw thread, two pieces of snap-gauges are symmetrical arranged in the lower section of trapezoidal screw and two swivel nuts, snap-gauge one end is welded on corresponding swivel nut, the perpendicular upward bending-like in the other end, clamping part is formed, to block the outer side wing edge of draw beam.The clamping device cancel traditional handicraft tie rod welding and gas flame cuttiug, avoid the damage to base material, it is easy to disassemble, can Reusability, improve production efficiency.And it is versatile, suitable in the draw beam of various different draw beam inner widths and state's iron car of flange width away from control.
Description
Technical field:
The present invention relates to technical field of vehicle manufacture, are to fill in a kind of rolling stock draw beam away from clamping specifically
It sets.
Background technique:
In rolling stock manufacturing process, in order to guarantee the width dimensions of every kind of vehicle draw beam, draw beam end all
Increase welded technique tie rod, change width after preventing central sill welding from shrinking influences hitch assembling.Remove technique tie rod
Gas flame cuttiug need to be used, cutting process easily causes middle flange of beam cut wound, and cuts, polishing reduction production efficiency.It cuts off simultaneously
Technique tie rod afterwards can not be reused substantially.
Summary of the invention:
In view of the above problems, the present invention is provided in a kind of rolling stock draw beam away from clamping device, the device
It is low in cost, easy to disassemble, it can Reusability.
To achieve the goals above, the present invention adopts the following technical scheme:
The present invention is provided in a kind of rolling stock draw beam away from clamping device, and the clamping device is by trapezoidal screw, swivel nut
And snap-gauge is constituted, and is symmetrical arranged two swivel nuts in trapezoidal screw two sides, trapezoidal screw and swivel nut are attached by screw thread, in ladder
The lower section of shape screw rod and two swivel nuts is symmetrical arranged two pieces of snap-gauges, and snap-gauge one end is welded on corresponding swivel nut, and the other end is in
Bending-like vertically upward forms clamping part.
The trapezoidal screw and swivel nut screw pitch are using the minimum value in nominal diameter.
The top of the trapezoidal screw is round end.
The material of the trapezoidal screw is 45# steel.
The beneficial effects of the present invention are:
1, in rolling stock is assembled with draw beam, the present invention is arranged in draw beam end, instead of in draw beam end
Increase welded technique tie rod, the variation of width, guarantees every kind of vehicle draw beam after capable of preventing central sill welding from shrinking
Width dimensions guarantee hitch assembling.
2, the present invention cancels welding and the gas flame cuttiug of traditional handicraft tie rod, avoids the damage to base material, easy to disassemble, can
Reusability improves production efficiency.
It 3, can be long by adjusting trapezoidal screw of the invention for state's iron car of different draw beam inner widths and flange width
The versatility away from clamping device in the draw beam is realized in the position of degree and swivel nut, and therefore, the present invention is suitable for various different tractions
Away from control in the draw beam of beam inner width and state's iron car of flange width.
Detailed description of the invention:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is mounting structure schematic diagram of the invention.
Appended drawing reference:
1-draw beam, 2- snap-gauge, 3- swivel nut, 4- trapezoidal screw.
Specific embodiment:
Invention is further described in detail with reference to the accompanying drawings and detailed description, but this should not be interpreted as to this
The range of the above-mentioned theme of invention is only limitted to following embodiments.
- Fig. 2 referring to Fig.1, the present invention are provided in a kind of rolling stock draw beam away from clamping device, and the clamping device is by ladder
Shape screw rod 4, swivel nut 3 and snap-gauge 2 are constituted, and two swivel nuts 3 are symmetrical arranged on trapezoidal screw 4, and trapezoidal screw 4 passes through with swivel nut 3
Screw thread is attached, and is symmetrical arranged two pieces of snap-gauges 2 in the lower section of trapezoidal screw 4 and two swivel nuts 3,2 one end of snap-gauge is welded on pair
On the swivel nut 3 answered, the perpendicular upward bending-like in the other end forms clamping part, to block the outer side wing edge of draw beam 1.It is described
Trapezoidal screw 4 and 3 screw pitch of swivel nut can be realized fine tuning, prevented the loosening of the clamping device using the minimum value in nominal diameter
With fall.The top of the trapezoidal screw 4 is round end, will not damage the web inner wall of draw beam 1, while easy to disassemble.It is described
The material of trapezoidal screw 4 is 45# steel, and overall structure good rigidity is unlikely to deform.
The clamping device is suitable for the rolling stock of non-solder structural impact seat, central sill group clock synchronization, in the end of draw beam 1
Using the clamping device, 1 inside of draw beam is contacted with trapezoidal screw 4, and outer side wing edge is connect with the clamping part of snap-gauge 2.Pass through rotation
Turn swivel nut 3 and guarantee that trapezoidal screw 4 holds out against middle web, and when snap-gauge 2 and outer side wing edge are completely fixed, stops rotating.The bottom of at
After frame group is completed end carriage, the clamping device is removed.By the adjustment to 3 positions of swivel nut, that is, snap-gauge, 2 position, can meet not
With the use on the edge of a wing of width.By processing the length of trapezoidal screw 4, the use of the draw beam of different inner widths can be met.
The above is optimum way of the invention, for the design field designer possibly also with the principle of the invention
Do the retouching of the forms such as name modifications, installation site exchange, material improvement, structural Shape Optimization, any profit on this basis
Decorations and optimization all fall in the scope of protection of the present invention.
