Description

Technical Field

[0001] This invention belongs to the field of mechanical processing equipment technology, specifically relating to a batch processing device for pipe laying robot linkages, and also to a batch processing method for pipe laying robot linkages. Background Technology

[0002] With the increasing automation of oil drilling and production equipment, the number of robotic pipe-laying devices is growing. Due to their high degree of automation, these devices significantly reduce the labor intensity of workers and improve operational efficiency and safety. The connecting rod is a crucial component of the pipe-laying robot, characterized by its small size and high requirement for hole coaxiality. Conventional machining methods for this part typically involve single-piece processing, requiring multiple clamping and alignment operations. Furthermore, it necessitates the use of two different machine tools, resulting in difficulties in clamping during machining, low production efficiency, and high manufacturing costs. Summary of the Invention

[0003] The purpose of this invention is to provide a batch processing device for pipe-laying robot linkages, which solves the problems of difficult clamping and low processing efficiency in the prior art when boring and milling are performed on different machine tools.

[0004] Another objective of this invention is to provide a method for mass production of pipe-laying robot linkages.

[0005] The technical solution adopted in this invention is a batch processing device for connecting rods of a pipe-laying robot, including a milling end face and boring tool and a milling inner stop tool. The milling end face and boring tool is used to process the two end faces of the connecting rod and to bore holes; the milling inner stop tool is used to process the milling inner stop of the connecting rod.

[0006] The invention is further characterized in that,

The mounting base includes a mounting base plate with multiple threaded holes along its length at the center of the upper surface. A vertical plate is vertically installed on one side of the mounting base plate, and multiple mounting baffles are evenly installed along its length on one side of the upper surface. The pressure plate is fixed to the mounting base plate with bolts. The mounting base and the pressure plate are used for milling the outer end face and boring the connecting rod and its stop.

[0008] The pressure plate has multiple weight-reducing holes and multiple bolt holes, which are located between every two weight-reducing holes.

[0009] The milling inner gauge fixture includes a second mounting base and a second pressure plate. The second mounting base includes a base plate, a side plate is vertically arranged on one side of the upper surface of the base plate, and protrusions are arranged at intervals on the other side of the base plate. An end plate is vertically arranged at one end of the upper surface of the base plate, and a U-shaped groove is provided at the end of the end plate near the side plate. The second pressure plate is provided with multiple weight reduction holes, and bolt holes are also provided at both ends of the second pressure plate. The second pressure plate is fixed to the second mounting base by bolts.

[0010] Another technical solution adopted in this invention is a method for mass processing of pipe-laying robot linkages, which is implemented according to the following steps:

[0011] Step 1: Fix the mounting base plate of mounting seat one to the workbench with bolts. Place the connecting rods flat on the mounting base plate. The connecting rods at the ends should be close to the vertical plate. Place copper pads at appropriate positions to make one end face of the connecting rod close to the mounting baffle.

[0015] Step 5: Using the side and top surfaces of the vertical plate as cutting surfaces, drill and bore one end of the connecting rod to form a hole, expand the stop, and record the coordinate values ​​of each hole;

[0016] Step 6: Loosen the bolts, rotate the mounting base 180°, and tighten the bolts with the side and top surfaces of the vertical plate facing each other; according to the coordinate values ​​of each hole, drill and bore the hole at the other end of the connecting rod, and expand the stop.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] According to the requirements for the connecting rod, the connecting rod needs to be machined on both ends with dimension a and the opening dimension b, such as Figure 1 As shown, hole ΦA and its stop are machined, and the coaxiality requirement of hole ΦA must be guaranteed. The workshop currently uses a VC-2000 CNC vertical machining center to machine the two end faces and the opening dimensions, and at the same time to serve as a reference for boring holes on a TKP6513 CNC boring and milling machine. An additional milling operation on the lower plane of the part is added, and all of these are single-piece machining operations.

[0033] Analysis revealed that the boring process is difficult to complete on a VC-2000 CNC vertical machining center. Therefore, a fixture was designed to machine the connecting rod separately on a TKP6511B CNC boring and milling machine. Due to the small structural dimensions of the connecting rod and the small hole size, clamping is difficult. Single-piece machining would result in low efficiency, and the designed fixture would also be small, affecting its clamping on the worktable. Therefore, a batch production approach was considered. This would improve production efficiency, ensure machining accuracy, and facilitate fixture clamping. Considering the machining requirements and processes of the connecting rod, and through various technical analyses and manufacturing costs, it was determined that two different fixtures would be used to complete the machining process separately.

[0034] Example 1

[0035] The present invention relates to a mass production device for connecting rods of a pipe-laying robot, comprising a milling end face and boring fixture and a milling inner stop fixture. The milling end face and boring fixture is used to process the two end faces of the connecting rod and to bore holes; the milling inner stop fixture is used to process the milling inner stop of the connecting rod.

[0036] like Figure 2 and Figure 3 As shown, the milling end face and boring tooling includes a mounting base 2 and a pressure plate 3; the mounting base 2 includes a mounting base plate 2-1, a plurality of threaded holes 2-2 are provided along the longitudinal direction at the center of the upper surface of the mounting base plate 2-1, a vertical plate 2-3 is provided vertically on one side end of the mounting base plate 2-1, and a plurality of mounting baffles 2-4 are uniformly provided along the longitudinal direction on one side of the upper surface of the mounting base plate 2-1;

[0037] like Figure 4 As shown, the pressure plate 3 has multiple weight-reducing holes and multiple bolt holes, which are located between every two weight-reducing holes. The pressure plate 3 is fixed to the mounting base plate 2-1 by bolts. There are two weight-reducing holes and three bolt holes.

[0038] Mounting base 12 and pressure plate 13 are used for milling the outer end face of the connecting rod and boring the hole and its stop. Mounting base 12 has a notch to facilitate boring and stop.

[0039] The 3×M1 threaded holes are used to fix the connecting rod to the mounting base 2 through the pressure plate 3, and the 2×Φ1 threaded holes are used to connect the mounting base 2 and the machine tool table.

[0040] Mounting bracket 12 ensures that the positioning reference surface is consistent during the machining of the outer end face of the connecting rod, and guarantees the parallelism requirements of the two end faces;

[0041] When boring the hole, simply loosen the bolts connecting the mounting base 2 to the worktable, while keeping the position of the connecting rod relative to the mounting base 2 unchanged and the tool setting reference plane unchanged, thus ensuring the coaxiality requirement of the hole.

[0042] Example 2

[0043] Unlike Example 1:

[0044] like Figure 5 and Figure 6 As shown, the milling inner stop tooling includes a mounting base 4 and a pressure plate 5. The mounting base 4 includes a base plate 4-1. A side plate 4-2 is vertically arranged on one side of the upper surface of the base plate 4-1, and protrusions 4-4 are arranged at intervals on the other side of the base plate 4-1. An end plate 4-3 is vertically arranged at one end of the upper surface of the base plate 4-1, and a U-shaped groove is provided at the end of the end plate 4-3 near the side plate 4-2.

[0045] Mounting bracket 24 has four empty notches to facilitate machining of the inner end face of the connecting rod.

[0046] like Figure 7 As shown, the pressure plate 2 5 is provided with multiple weight reduction holes, and bolt holes are also provided at both ends of the pressure plate 2 5; the pressure plate 2 5 is fixed to the mounting base 2 4 by bolts.

[0047] Example 3

[0048] The present invention provides a method for batch processing of pipe-laying robot linkages, which is implemented according to the following steps:

[0049] Step 1: Fix the mounting base plate 2-1 of mounting seat 2 to the workbench with bolts. Place the connecting rods 1 flat on the mounting base plate 2-1 respectively. The connecting rods 1 at the end should be close to the vertical plate 2-3. Put copper pads at appropriate positions so that one end face of the connecting rod 1 is close to the mounting baffle 2-4.

[0050] Step 2: Fix the pressure plate 3 to the mounting base plate 2-1 using multiple bolts;

[0051] Step 3: Mill one side of connecting rod 1;

[0052] Step 4: Loosen the pressure plate 3, the side of the connecting rod 2 has been milled and is tightly attached to the mounting baffle 2-4, tighten the pressure plate 3, and mill the other side of the connecting rod 1.

[0053] Step 5: Using the side and top surfaces of the vertical plate 2-3 as cutting surfaces, drill and bore one end of the connecting rod 1 to form a hole, expand the stop, and record the coordinate values ​​of each hole;

[0054] Step 6: Loosen the bolts, rotate the mounting base 1-2 180°, and tighten the bolts with the side and top surfaces of the vertical plate 2-3 as the cutting surfaces; according to the coordinate values ​​of each hole, drill and bore the hole at the other end of the connecting rod 1, and expand the stop.

[0055] Step 7: Place the machined side connecting rod 1 against the end plate 4-3 and side plate 4-2; cover with pressure plate 5, and fix the connecting rod 1 and base plate 4-1 on the worktable with bolts; with the back of end plate 4-3 facing the tool, move the coordinates and machine the milling inner stop of the connecting rod.

[0056] The present invention provides a batch processing method for pipe-laying robot connecting rods. First, the outer end face of the connecting rod is machined, with four rods processed at a time. Then, the tool-setting reference is established, and each hole and its stop are bored, with the position coordinates of each hole recorded. When boring the holes, simply loosen the bolts connecting the mounting base to the worktable, establish a unified alignment reference and tool-setting reference, and bore the hole and its stop on the other side. This batch processing method improves processing efficiency and reduces production costs.
