Description

Heavy Weight Assembly Positioning Device {POSITIONING APPARATUS FOR ASSEMBLING HEAVY OBJECT}

The present invention relates to a weight assembly position determination device, and more specifically, when the weight of the object to be divided into a plurality of parts, such as the cylinder frame of the marine engine to be configured to precisely assemble or process a plurality of parts It relates to a mass assembly positioning device for.

In the construction of ships and the manufacture of large machines, there is a need to machine or assemble various heavy items. In particular, a marine engine is provided with a heavy component having a large size such as a frame box, a cylinder frame, a bed plate. It is preferable that all of these objects are made of a single material using a cylindrical material, but the objects of such a weight are manufactured in the form of small quantities of various kinds, so that a dedicated machine for one component is manufactured. Even if the machine is processed in a dedicated machine, there are many restrictions in terms of handling and transporting and installing the processed product.

Therefore, the object of such a weight is usually divided into several parts and processed, and each processed part is assembled to complete a product. As such, when one finished product is divided (configured) into a plurality of parts, it can be processed by a general-purpose machine, and it is true that it is easier than the case of integrally configuring the handling, transportation, and installation during processing. However, when the components of the heavy weight are composed of a plurality of parts to form an integrally completed product through assembly, there is a problem in maintaining precision in processing and assembly.

The following are proposed techniques for effectively assembling or processing a heavy object.

Republic of Korea Patent Publication No. 0328726 "Disassembly jig for heavy load" proposes a jig for easy disassembly and assembly of various types of heavy materials having different positions and intervals of the bolt.

Korean Patent Laid-Open Publication No. 1999-0060975 "positioning device of the workpiece" is fixed to the stable position by the clamp means installed on the V-block, the cam follower and the roller in close contact with the workpiece, regardless of whether the workpiece is large or asymmetrical When positioning large workpieces such as the rear axle to the cutting device by positioning them, it is possible to fix and position the workpieces by a single operator, and to maintain the position of the seated workpieces. The product can be made uniform.

Korean Patent Laid-Open Publication No. 2003-0033757 "Jig for cylinder block processing" proposes a jig for starting a cylinder block to improve the machining quality of the embedded liner cylinder block.

Republic of Korea Utility Model Registration No. 20-0324049 "Large diesel engine for end cover processing jig device" proposes a jig for the manufacture of a cover to protect the driving part of the engine is mounted in the flywheel position relative to the body in large marine engines Doing.

On the other hand, as shown in Figure 1, the cylinder frame 100 of the marine engine is composed (designed) of a plurality of blocks (110, 120, 130), each of the processing process of each of the blocks (110, 120, 130) is completed After the assembly, the parts to be processed as a whole are processed (REAM work, etc.). And after being assembled and processed as a whole, it is transported to the ship which is disassembled and installed again, and is installed again through the assembly process.

In this case, the conventional cylinder frame 100 forms flanges 112, 122, 124, and 132 corresponding to each block 110, 120, and 130 for assembly of the blocks 110, 120, and 130, respectively. By forming the assembly holes 140 to which the alignment pins 150 are coupled to the flanges 112 and 122, 124 and 132, the respective blocks 110, 120, and 130 may be assembled.

The assembly of such a cylinder frame 100 first lifts the second block 120 with a crane in a state in which the first block 110 is placed, and puts the dowel pin 150 in the lower part of the second block 120 while assembling holes. It is coupled to the 140 to assemble the horizontal alignment between the blocks (110, 120, 130). Of course, the following blocks are assembled through this process.

However, this assembly method requires a number of workers (crane worker, horizontal observation and pedestal insertion worker, dowel pin coupling worker), there is a problem that takes a lot of work time (about 6 hours). In particular, such a problem occurs in the portion that couples the dowel pin 150 to the assembly hole 140. Usually the dowel pin 150 used in such assembly is processed to fit in the middle for the precision of the fit, the worker moves the assembly hole between the two blocks (100 and 120, 120 and 130) while moving the crane depending on the time 140 is matched, and the dowel pin 150 is inserted. Therefore, for precise assembly, the alignment pins 150 should be inserted while the two assembly holes 140 are exactly matched. However, in practical operation, the alignment pins are roughly leveled, and the alignment pins 150 are hammered and forced to be inserted. To be combined.

Eventually, according to this method, a large number of manpower is input, but the work time is long, the work efficiency is low, and a large number of workers deal with heavy weights, so there is always a risk of a safety accident, and the assembling holes 140 are not matched. Since the dowel pin 150 is forcibly coupled, it is difficult to disassemble and reassemble afterwards, and there is a problem in that product quality is degraded.

In order to improve such a problem, the proposed devices can be applied and applied as described above, but the proposed prior arts are proposed for a specific product, and a problem that is provided in a dedicated form for an assembly or a processing process is not provided. have. That is, the conventionally proposed devices have to be manufactured separately for a specific product, and there is a problem in that they can be applied to any one area in the processing or assembly area and can be used in a very limited manner.

Therefore, the present invention has been proposed to solve such a problem, and when the precise assembly is required to simultaneously process or install a heavy component composed of a plurality of parts such as a marine engine, it is possible to easily assemble the parts while providing high assembly precision. It is an object of the present invention to provide a new type of mass assembly positioning device.

In particular, the present invention is the weight of the first part and the second part having the assembly hole 140 corresponding to each other, such as the cylinder frame of the marine engine described above (that is, the second block 120 is the second block relative to the first block 110) The first part and the second part by assembling and aligning through the assembly hole 140 to process or install the third part 130, and the first part with respect to the third block 130. In contrast, it is an object of the present invention to provide a weight assembly positioning device of a new type that can be applied to a variety of weights in common to enable precise assembly.

According to a feature of the present invention for achieving the above object, the present invention provides the first and second parts in order to process or install a heavy part consisting of a first part and a second part formed with a corresponding assembly hole A heavy weight assembly positioning device for assembling and aligning through an assembling hole, comprising: an outer circumferential surface insertable into the assembling hole and passing through a center of a first end and a second end, the first end from the first end; An expansion sleeve having an inner circumferential surface formed to have a slope that is reduced to two ends and extendable in a direction of the outer circumferential surface; A control bar having an inclination that decreases from the first end to the second end like the inner circumferential surface of the expansion sleeve, the adjustment bar being inserted into and engaged in the direction of the second end from the first end of the expansion sleeve; And an adjustment bar conveying unit coupled to the adjustment bar, the adjustment bar being moved while moving from the first end of the expansion sleeve to the second end to extend the expansion sleeve in the direction of the outer circumferential surface. After positioning in the corresponding assembly hole of the part and the second part, the adjusting bar transfer unit is used to move the adjusting bar from the first end to the second end of the expansion sleeve so that the expansion sleeve extends in the circumferential direction. Align the assembly positions of the first part and the second part.

In the above-described heavy weight assembly positioning device according to the present invention, the expansion sleeve is formed by cutting a predetermined length so as to be removed between the inner peripheral surface and the outer peripheral surface of the expansion sleeve from the first end to the second end direction; And a second slot formed by cutting a predetermined length so as to be removed between the inner and outer circumferential surfaces of the expansion sleeve in the direction of the first end from the second end.

In the above-described heavy weight assembly positioning device according to the present invention, the control bar transfer unit is supported on the outer surface of the second part on the opposite side of the first part and is positioned on the assembly hole, and a through hole parallel to the assembly hole is provided. A stop block formed; A transfer shaft having one end coupled to the second end of the adjustment bar, the other end protruding out of the second part through the through hole of the stop block, and the other end having a screw formed therein; A nut coupled to a screw at the other end of the transfer shaft and having a nut supported by the stop block may rotate the nut to move the adjusting bar from the first end of the expansion sleeve to the second end.

2 is a view for explaining the technical idea of a weight assembly positioning device according to the present invention.

Referring to FIG. 2, the heavy object assembly position determining apparatus 10 according to the present invention processes a heavy object composed of the first part 1 and the second part 3 having the assembly holes 2 and 4 corresponding thereto. The first part 1 and the second part 3 are assembled and aligned through the assembly holes 2 and 4 for installation.

Therefore, the weight assembly position determining apparatus 10 according to the present invention does not require a separate configuration for assembly or disassembly for the weight is usually configured to assemble using a dowel pin. That is, the heavy weight assembly position determining apparatus 10 according to the present invention is directly applied without structural changes such as a frame box, a cylinder frame, a bed plate, etc. You can do it. In addition, the heavy weight assembly position determining apparatus 10 according to the present invention can be obtained by assembling high precision by forming only the assembly holes corresponding to each other without adding separate components for assembly to the weight to be bonded It is possible to reduce the burden, and to minimize the configuration added to the weight for assembly.

Meanwhile, in the present invention, the weight component defined as the first part 1 and the second part 3 is not simply a term meaning two components, but a term for distinguishing the elements according to the assembling order. That is, as mentioned above, the cylinder frame of the marine engine is divided into a plurality of blocks, and when assembling the first block and the second block in the plurality of blocks constituting the cylinder frame like this, the first block corresponds to the first part, The second block corresponds to the second part. When assembling the first block and the second block and assembling the third block, the first part corresponds to the second block and the second part corresponds to the third block. Therefore, in the present invention, the terms of the first part 1 and the second part 3 are used to distinguish the weights in the assembly relationship with each other.

Again, referring to FIG. 2, the weight assembly positioning device 10 according to the present invention includes an extension sleeve 20, an adjustment bar 40, and an adjustment bar transfer unit 50. Heavy-weight assembly positioning device 10 having such a configuration is to position the expansion sleeve 20 in the corresponding assembly holes (2, 4) of the first part (1) and the second part (3), and then adjusting bar By using the transfer unit 50, the adjusting bar 40 is moved from the first end 22 to the second end 24 of the expansion sleeve 20 so that the expansion sleeve 20 extends in the direction of the outer circumferential surface. The assembly positions of the part 1 and the second part 30 are aligned.

As described above, the assembly principle of the heavy-weight assembly positioning device 10 according to the present invention basically fixes the coupling position of the two heavy weights by engaging the alignment pins on the assembly holes 2 and 4 designed with the same central axis as in the related art. It is. Therefore, the weight assembly position determination device 10 according to the present invention can be expected the effect of pin assembly that is usually used for precise fit.

At this time, the weight assembly position determining apparatus 10 according to the present invention can be expected to be excellent workability than to determine the position of the two weights by using a conventional pin, while obtaining the effect of pin alignment. In other words, unlike the conventional need for a large number of workers, the assembly work can be performed more easily with only one worker, and it is possible to reduce the burden on the worker since there is no need for forced punching, and the two heavy materials (1, 3) Since the assembly position can be precisely determined even after roughly aligning the positions of the assembly holes 2 and 4, the work time can be greatly reduced while eliminating the risk of a safety accident. For example, when the assembly of a heavy object using a conventional dowel pin takes about 6 hours, but as a result of the application of the weight assembly positioning device 10 according to the present invention, a single operator was able to precise assembly with a working time of 1 hour .

Referring again to FIG. 2, the expansion sleeve 20 of the heavy weight assembly positioning device 10 according to the invention is inserted into the assembly holes 3, 4 of the first part 1 and the second part 3. It has a possible outer peripheral surface 26. And an inner circumferential surface 28 formed to have an inclination that is reduced from the first end 22 to the second end 24 while penetrating across the centers of the first end 22 and the second end 24. .

In this case, the expansion sleeve 20 is formed to be expandable in the direction of the outer circumferential surface 26. Various configurations may be applied to the configuration in which the expansion sleeve 20 is expandable in the direction of the outer circumferential surface 26. For example, a preferred embodiment of the present invention to be described later to form a slot in the longitudinal direction of the expansion sleeve 20 in consideration of the strength, so that the slots are staggered from both ends for uniform expansion. Of course, the structure that allows the expansion sleeve 20 to extend in the direction of the outer circumferential surface 26 may be applied to various types of slots such as slots in the circumferential direction, slots in the helical direction, but sufficient rigidity for the load of the two heavy materials. It is necessary to have a structure and to apply a structure that is easy to work.

Meanwhile, in the weight assembly positioning device 10 according to the present invention, the outer circumferential surface 26 of the expansion sleeve 20 is formed in parallel with the assembling holes 2 and 4, and the inner circumferential surface 28 is formed to have an inclination. Through such a configuration, the expansion sleeve 20 is moved by moving the adjustment bar 40 to be described later from the assembly hole 2 position of the first part 1 to the assembly hole 4 position of the second part 3. It is expanded so that the positions of the two parts 1, 3 are aligned. In this case, the outer circumferential surface 26 of the expansion sleeve 20 has a diameter slightly smaller than that of the assembly holes 2 and 4 so that the preparation operation is convenient. In other words, the assembly holes (2, 4) of the two parts (1, 3) to roughly match the position and to facilitate the positioning of the expansion sleeve (20).

In this case, the assembling holes 2 and 4 of the two heavy materials (ie, the first and second parts 1 and 3) may be formed in parallel, but in some cases, they may be inclined. In this case, the technical configuration that the outer peripheral surface 26 is formed to have an inclination corresponding to the inclination of the assembling holes 2 and 4 in the expansion sleeve 20 of the heavy weight assembly positioning device 10 according to the present invention It will be under the technical idea of the invention.

In addition, the overall length of the expansion sleeve 20 is to have a length that is caught in the assembly holes (2, 4) of both parts (1, 3). And the end is to be located inside the assembly hole (4) of the second part (2). Of course, the end of the expansion sleeve 20 can be configured to be out of the assembling hole 4 of the second part 2, in this case there is a problem that the configuration for fixing the adjustment bar transfer unit 50 is complicated.

Again, referring to FIG. 2, the adjustment bar 40 of the heavy weight assembly positioning device 10 according to the present invention, like the inner circumferential surface 28 of the expansion sleeve 20, has a second end (from the first end 42). With a slope that is reduced to 44, it is inserted into and engaged in the direction of the second end 24 from the first end 22 of the expansion sleeve 20. The adjusting bar 40 is moved from the first part 1 in the direction of the second part 3 so as to expand the above-described extension sleeve 20 so as to assemble the holes 2, 4 of the two parts 1, 3. Make sure that the center of aligns with the same line.

The adjusting bar conveying unit 50 is coupled to the adjusting bar 40, and the adjusting bar 40 is coupled while being moved from the first end 22 of the expansion sleeve 20 to the second end 24 of the expansion sleeve 20. 20 is extended in the direction of the outer circumferential surface 26. Such control bar transfer unit 50 may be applied in various configurations. For example, a preferred embodiment of the present invention described below is configured to be assembled in the field with only a basic tool (spanner) without additional devices, but for the convenience of the operator, the adjustment bar transfer unit 50 is an actuator such as a hydraulic cylinder or a motor. You will be able to connect to and use it.

As such, the heavy weight assembly position determining apparatus 10 according to the present invention does not require a separate configuration for assembly or disassembly for the heavy weight that is usually configured to assemble using a dowel pin, for a marine engine that is configured in a conventional manner It can be applied immediately without structural change of frame box, cylinder frame, bed plate, etc. In addition, it is possible to reduce the burden of the design because it is possible to obtain a high-precision assembly by forming only the assembly holes corresponding to each other without adding separate components for assembly to the weight to be bonded, and added to the weight for assembly Configuration can be minimized. Therefore, the weight assembly position determining apparatus 10 according to the present invention can easily assemble parts while providing high assembly precision when precise assembly is required to simultaneously process or install a heavy component composed of a plurality of parts such as a marine engine. have.
