Abstract
The utility model discloses a movable support of a pipeline hot melting butt welding machine. The movable support of the pipeline hot melting butt welding machine comprises a rack, a hydraulic pressure actuator cylinder assembly, a lower fixing support frame and an upper movable support frame. The movable support of the pipeline hot melting butt welding machine further comprises bolt connection structures. The lower fixing support frame and the upper movable support frame are fixed together through the bolt connection structures which are placed at the front end of the lower fixing support frame and at the back end of the lower fixing support frame. Each bolt connection structure comprises a screw with a nut and a bolt pin shaft. Screws are connected with the front end and the back end of the lower fixing support frame through bolt pin shafts. According to the movable support of the pipeline hot melting butt welding machine, a relatively sealed structure is formed by mutual coordination among the screws, the bolt pin shafts and a screw anti-dropping pin, and the relatively sealed structure enables the lower fixing support frame and the upper movable frame to be in an incompletely separating condition. Losses of components and parts are avoided. Concentricity deviation caused by interchange and coordination of the upper movable support frame and the lower fixing support frame when the upper movable support frame is taken up and taken down in a traditional structure is effectively eliminated . Precision of clamping of a pipeline is guaranteed, production efficiency is improved, and further welding effects are ensured.
Description
Technical field
The utility model relates to a kind of travel(l)ing rest of pipe hot melting butt welder.
Background technology
The travel(l)ing rest of pipe hot melting butt welder includes with lower member in the prior art: fixed frame, hydraulic power hydraulic cylinder assembly, lower fixed support, upper travel(l)ing rest and the bolt that lower fixed support and upper travel(l)ing rest are connected together.
Yet the travel(l)ing rest of existing pipe hot melting butt welder is in off working state, lower fixed support and upper travel(l)ing rest are all separated fully, and the mode that is bolted again in work is connected together lower fixed support and upper travel(l)ing rest.But welding machine is in the work of reality, the upper travel(l)ing rest that often lower fixed support and upper travel(l)ing rest is split the trouble that comes very and splits can frequent losing, and have influence on sometimes the precision of pipeline clamping because the interchangeability between lower fixed support and the upper travel(l)ing rest is bad.
Therefore, necessary prior art is improved to address the aforementioned drawbacks.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of processing, the travel(l)ing rest of the easy pipe hot melting butt welder of assembling and setting.
The utility model adopts following technical scheme: a kind of travel(l)ing rest of pipe hot melting butt welder, it includes frame, hydraulic power hydraulic cylinder assembly, lower fixed support and upper travel(l)ing rest, the travel(l)ing rest of described pipe hot melting butt welder also includes lower fixed support and upper travel(l)ing rest is fixed in together two bolt fastening structures, two bolt fastening structures are separately positioned on lower support bracket fastened forward and backward two ends, comprise screw rod and bolt bearing pin with nut, screw rod is connected to lower support bracket fastened front-end and back-end by the bolt bearing pin.
As further improvement of the utility model, the rear end on the described lower fixed support is provided with supports the supplemental support convex shoulder that upper travel(l)ing rest is erect.
As further improvement of the utility model, the rear end of described upper travel(l)ing rest is provided with the screw rod locking pin.
As further improvement of the utility model, the cross section of described screw rod lower end is square structure, to prevent upper travel(l)ing rest sideways when the supplemental support convex shoulder is erect.
The utlity model has following beneficial effect, pass through screw rod in the travel(l)ing rest of the pipe hot melting butt welder in the utility model, the structure that complements each other to form a relative closure between bolt bearing pin and the screw rod locking pin, structure by this relative closure is so that be in incomplete released state between lower fixed support and the upper travel(l)ing rest, avoid losing of parts, and effectively eliminated in the traditional structure, upper travel(l)ing rest takes off, cooperate the Concentricity tolerance that causes with lower fixed support exchange, guaranteed the precision of pipeline clamping, improve production efficiency, and then guaranteed the effect of welding.
Description of drawings
Fig. 1 is that travel(l)ing rest and lower fixed support be separately and the structural representation of erectting on the utility model embodiment.
Fig. 2 is the structural representation that travel(l)ing rest and lower fixed support are combined on the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Please refer to illustrated in figures 1 and 2ly, the travel(l)ing rest of the utility model pipe hot melting butt welder includes frame 1, hydraulic power hydraulic cylinder assembly 2, lower fixed support 3, upper travel(l)ing rest 4, lower fixed support 3 and upper travel(l)ing rest 4 is fixed in together bolt fastening structure.Bolt fastening structure is arranged on lower support bracket fastened forward and backward two ends, comprises screw rod 5 and bolt bearing pin 6 with nut 8, and screw rod 5 is connected to lower support bracket fastened front-end and back-end by bolt bearing pin 6.The rear end of upper travel(l)ing rest 4 also is provided with screw rod locking pin 7 and lower support bracket fastened rear end is provided with the supplemental support convex shoulder 30 that supports upper travel(l)ing rest setting.
The composition surface 9 at lower fixed support 3 and upper travel(l)ing rest 4 forward and backward two ends is smooth arcuate structure in the utility model, thereby is convenient to the separation between lower fixed support 3 and the upper travel(l)ing rest 4.
In the utility model by the structure that complements each other to form a relative closure between screw rod 5, nut 8, bolt bearing pin 6 and the screw rod locking pin 7, structure by this relative closure is so that lower fixed support 3 and upper travel(l)ing rest 4 are in incomplete released state all the time, and because the existence of supplemental support convex shoulder 30, can landing so that upper travel(l)ing rest 4 just in time is erected on the supplemental support convex shoulder 30 of lower fixed support 3.The cross section of screw rod lower end 51 is square, thereby can sideways so that upper travel(l)ing rest 4 is erect reliably.
Please refer to illustrated in figures 1 and 2ly, the assembling process of the travel(l)ing rest of pipe hot melting butt welder of the present utility model comprises the steps: the first step: frame 1, hydraulic power hydraulic cylinder assembly 2,3 assemblings of lower fixed support are fixed in together; Second step: with lower fixed support 3, screw rod 5 and connection bearing pin 6 assembly and connections together; The 3rd step: upper travel(l)ing rest 4, screw rod 5 usefulness nuts 8 assembly and connections of locking pin 7 will be housed, and then finish the lower fixed support of pipe hot melting butt welder and the assembling process of upper travel(l)ing rest.
And needs separate lower fixed support 3 with upper travel(l)ing rest 4 when, only the nut 8 in the screw mechanism of forward and backward both sides and screw rod 5 need to be unclamped, upper travel(l)ing rest 4 upwards is erected on the convex shoulder 30 after the upset, and do not need whole upper travel(l)ing rest 4 is taken off from lower fixed support 3, convenient separation and avoid travel(l)ing rest 4 after taking off owing to the part that causes of carelessness is lost.And the upper travel(l)ing rest of the pipe hot melting butt welder in the utility model does not need to take off, travel(l)ing rest exchanges with lower fixed support and cooperates the Concentricity tolerance that causes on effectively having eliminated in the traditional structure, guaranteed the precision of pipeline clamping, improve production efficiency, and then guaranteed the effect of welding.
