Description

Technical Field

[0001] The utility model relates to the field of tooling, in particular to a fixed tooling used for cutting steel pipe parts. Background Art

[0002] Wind power generation has developed rapidly in recent years due to its advantages of no pollution and low construction cost. The processing efficiency and quality of the internal parts of the gearbox play a vital role. The gear transmission process inside the gearbox cannot be separated from the lubrication of lubricating oil. Usually, many oil pipes are installed inside and outside the gearbox to ensure lubrication. There are various oil pipes used on the gearbox, and the lengths are different. Before installation, the oil pipes need to be cut into specified lengths according to the needs. Usually, the steel pipes are directly placed on the steel pipe cutting machine for processing. Due to the complex structure of the gearbox body and the direct casting of the inner cavity of the box body, there are certain errors in the size of the box body. Sometimes the oil pipe needs to be matched according to the actual situation inside the box body. The oil pipe sometimes only needs to be cut a few millimeters on the original basis, and it needs to be cut by the cutting machine for the second time. If it is sent to the cutting machine for cutting again, it will not only waste the production capacity of the cutting machine, but also affect the assembly efficiency of the oil pipe.

Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the utility model, the following will be combined with the drawings and specific embodiments to explain the utility model in more detail.

[0022] It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more centered elements can exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. The terms "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0023] like Figure 1 , Figure 2 As shown:

[0024] The lower clamping block 1 is a square steel section with a certain length. The square steel section is a hollow square tube type, and the wall thickness of the square steel section used is required to be consistent at the top, bottom, left and right.

[0025] The upper clamping block 2 and the lower clamping block 1 are square steel sections of the same specifications and types, and their lengths are also the same.

[0026] A V-shaped notch 11 is opened in advance in the middle of the upper surface of the lower clamping block 1 by a cutting machine, and a V-shaped notch 21 is opened in advance in the middle of the lower surface of the upper clamping block 2. The V-shaped notch 21 of the upper clamping block 2 corresponds to the V-shaped notch 11 of the lower clamping block 1. The steel pipe 3 to be processed is placed between the V-shaped notch 21 of the upper clamping block 2 and the V-shaped notch 11 of the lower clamping block 1.

[0027] Two mounting holes of the same specification are opened in advance on the lower plate of the lower clamping block 1, and the two mounting holes are symmetrically distributed on the lower clamping block 1 relative to the V-shaped notch 11. Two threaded holes are processed in advance on the tooling base 5, and the positions of the threaded holes are determined according to the mounting holes processed in advance on the lower clamping block 1, that is, the positions of the threaded holes and the mounting holes correspond. After the bolts 4 pass through the mounting holes on the lower clamping block 1, they are screwed into the threaded holes processed in advance on the tooling base 5, and the lower clamping block 1 is securely connected to the integral tooling base 5 by tightening the two bolts 4 on the left and right.

[0028] The guide rail 6 is a cylindrical steel member having a certain length.

[0029] The upper plate and the lower plate of the upper clamping block 2 are provided with two guide rail through holes of the same specification on the left side in advance. Two guide rail through holes of the same specification are also provided on the right side in advance, and are symmetrically distributed with the two guide rail through holes on the left side relative to the V-shaped notch 21. There are a total of 4 guide rail through holes on the upper clamping block 2.

[0030] A guide rail through hole is opened in advance on the left side of the upper plate of the lower clamping block 1. A guide rail through hole of the same specification is also opened in advance on the right side, and is symmetrically distributed with the guide rail through hole on the left side relative to the V-shaped notch 11.

[0031] The guide rail through hole of the upper clamping block 2 corresponds to the guide rail through hole of the lower clamping block 1 in position.

[0032] Pass the guide rail 6 through the guide rail through hole of the upper plate of the upper clamping block 2, then through the guide rail through hole of the lower plate of the upper clamping block 2, and continue to pass through the guide rail through hole of the upper plate of the lower clamping block 1 until the lower end of the guide rail 6 contacts the lower plate of the lower clamping block 1, and then fix the lower end of the guide rail 6 to the lower plate of the lower clamping block 1 by welding.

[0033] The utility model uses two guide rails 6 in total, and they are symmetrically distributed. Since the upper plate and the lower plate of the upper clamping block 2 each have a guide rail through hole, the guide rail 6 and the lower clamping block 1 are fixed, so the upper clamping block 2 can move on the guide rail 6.

[0034] The crossbeam 7 is a rectangular steel plate with a certain thickness, and the two ends of the crossbeam 7 are fixed to the guide rails 6 on both sides of the tooling by welding. A through hole is opened in the center of the crossbeam 7 in advance, and a round nut 8 is welded above the through hole of the crossbeam 7. The position of the round nut 8 corresponds to the position of the through hole of the crossbeam 7.

[0035] A handle 10 is welded to the head of the bolt 9 in advance to facilitate turning the bolt 9 .

[0036] The threaded part of the bolt 9 is screwed into the round nut 8, and the handle 10 is continuously turned to control the bolt 9 to pass through the through hole on the crossbeam 7 until the bolt 9 hits the upper plate of the upper clamping block 2. Since the upper clamping block 2 can move on the guide rail 6, the gap between the upper clamping block 2 and the lower clamping block 1 can be adjusted by adjusting the position of the bolt 9, thereby achieving the purpose of clamping the steel pipe 3.

[0037] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the utility model.
