Description

Technical Field

[0001] The present invention relates to a support equipment component for coal mining in coal mines, and particularly to an assembly and processing method for a connecting rod body. Background Art

[0002] The fully-mechanized intelligent hydraulic support is an important support equipment for coal mining in coal mines, and the connecting rod is an important connecting component of the hydraulic support, playing a role as a connecting link between other components.

[0003] Currently, the well-known processing method is to process according to the requirements of the design drawings. This traditional processing method has cumbersome procedures and requires several transfers, which affects production efficiency and increases the labor of workers.

[0004] Existing technology, assembly and processing method:

[0005] Such as Figure 1a 、 Figure 1b shown, pre-assembly, including steps:

[0006] 1. There is a φ101 hole on one main bar 1, which is flame-cut into a φ81 hole;

[0007] 2. There are φ101 holes on two gusset plates 2, which are flame-cut into φ81 holes;

[0008] 3. One main bar 1 is placed on the platform, ensuring an outer dimension of 5 mm. The two gusset plates 2 are grouped on one main bar 1 and welded well;

[0009] 4. One main bar 1 and two gusset plates 2 become a pre-assembled component, and the inner hole is rough-bored to a φ91 hole together.

[0010] Such as Figure 2a 、 Figure 2b shown, overall assembly and processing, including steps:

[0011] 1. After two pre-assembled main bar components 4 are rough-bored to a φ91 hole, they are assembled together with a shaft passed through. It is required that the diameter difference between the shaft and the hole is 1 mm (i.e., the rough-boring is a φ91 hole and the shaft is φ90);

[0012] 2. Use the cover plate 5 to connect and assemble and weld well to form a connecting rod body;

[0013] 3. The connecting rod body is overall precision-bored to a φ101 hole according to the drawing requirements.

[0014] Disadvantages of the existing technology:

[0015] 1. Processing according to the requirements of the drawing design has cumbersome procedures and requires several transfers, which affects production efficiency.

[0016] 2. When designing holes with too large diameters, such as φ180 holes, φ200 holes, etc., after rough boring, the riveters in the production workshop need to assemble with a very heavy solid shaft. One riveter simply cannot move the shaft, and it requires multiple people to cooperate and a crane to lift it for shaft insertion and assembly, which increases the labor of workers and also poses a risk of personal safety accidents.

[0017] In view of this, the present invention is specifically proposed. Summary of the Invention

[0018] The purpose of the present invention is to provide a connecting rod body assembly and processing method to solve the above technical problems existing in the prior art.

[0019] The purpose of the present invention is achieved through the following technical solutions:

[0020] The connecting rod body assembly and processing method of the present invention includes the steps:

[0021] A. Pre-assembly to form a main reinforcement pre-assembly 4;

[0022] B. Overall assembly and processing, specifically including the steps:

[0023] B1. Stand the backing tire 3 on the platform and adjust the locking of the top screws on both sides of the backing tire 3 according to the pitch dimension required for the main reinforcement on the design drawing;

[0054] In order to more clearly show the technical solution provided by the present invention and the technical effects produced, the following describes in detail the embodiment provided by the embodiment of the present invention with specific examples.

[0055] Embodiment 1

[0056] As Figure 3a 、 Figure 3b 、 Figure 4 shown:

[0057] Cancel the rough boring process. First, adopt the form that the part is flush and square with one end of the outer circle arc of the main reinforcement bar against the fixture, and the two sides are against the fixture to prevent tipping, then assemble it into a structural part, and finally adopt the processing method of overall boring.

[0058] Specifically, it includes:

[0059] Assembling and processing method:

[0060] As Figure 3a 、 Figure 3b shown, pre-assembly includes the steps of:

[0061] 1. For the φ101 hole of the main reinforcement bar 1, flame cut it into a φ88 hole;

[0062] 2. For the φ101 holes of the two attaching plates 2, flame cut them into φ88 holes;

[0063] 3. Place the main reinforcement bar 1 on the platform, ensure the outer dimension of 5 mm, and assemble and weld the two attaching plates 2 on the main reinforcement bar 1.

[0064] As Figure 4 shown, overall assembly and processing includes the steps of:

[0065] 1. Stand the fixture 3 on the platform and lock it with the jackscrew;

[0066] 2. According to the pitch distance dimension required for the main reinforcement bar on the design drawing, adjust the jackscrews of the two side fixtures 3 and lock them to prevent the main reinforcement bar from tipping;

[0067] 3. Put the main reinforcement bar pre-assembly 4 into it, and make one end arc of the main reinforcement bar tightly against the fixture 3;

[0068] 4. Use the cover plate 5 to connect and assemble and weld it well to form the connecting rod body.

[0069] 5. According to the requirements of the drawing, the connecting rod body is integrally machined and bored to form a φ101 hole.

[0070] Advantages of the present invention:

[0071] Compared with the original processing technology, the optimized processing technology reduces one rough boring process, reduces one structure assembly for shaft stringing, and reduces the transfer between workshops twice. The optimized processing technology method eliminates the need to draw positioning reference lines.

[0072] It is convenient for assembly and greatly improves the production efficiency.

[0073] Key technical points of the present invention:

[0074] For the main reinforcement and the processing holes on the main reinforcement, one end of the outer arc of the main reinforcement is used as the positioning reference by relying on the fixture to be flush.

[0075] The riveter can omit the procedures of scribing and positioning for assembly.

[0076] After assembly and welding, only one overall boring process is required to meet the requirements of the drawing design.

[0077] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
