Description

  The present invention relates to a joining method and a joining structure of a joining portion of an assembly tank such as a coolant tank, and more specifically, joining between the constituent parts of a coolant tank and other assembly liquid tanks assembled by joining a plurality of constituent parts. It relates to the method and the structure of the joint.

  For example, a relatively large liquid tank, such as a coolant tank for storing coolant attached to a machine tool, is assembled by joining the joint end faces of two box-shaped container constituent parts lacking one side face to face each other. . In this case, as shown in FIG. 5, joint flanges 31 a to 31 d (41 a to 41 d) are provided on both sides and upper and lower sides of the joint end surface of each container component, and the joint flanges 31 a to 31 d of one container component are The joint flanges 41a to 41d of the other container component are bolted.

  For this purpose, a large number of bolt holes 32, 42 are drilled in each of the joining flanges 31a-31d, 41a-41d. When joining, a sealing material such as silicone is applied to the facing surfaces of the respective joining flanges 31a to 31d and 41a to 41d, and the flange surfaces are leveled with a paddle, a leveler, etc. before the sealing material is solidified. After confirming this, the flanges are butted together and bolted.

  In the case of this conventional joining method, it is necessary to join after confirming that the flange surface is horizontal, but the work requires skill, and each joining flange on both sides and upper and lower sides It is necessary to open a large number of bolt holes 32 and 42 over the entire length of the machine, and it takes time and labor for tightening a large number of bolts. There are drawbacks.

  Also, since the lower flanges 31c and 41c cannot be bolted from the outside, openings 33 and 43 are provided on the inner bottom surface of the container component, bolted from the inside through the holes, and after the bolting is completed, the openings 33 and 43 are opened. The method of closing by welding a series of bottom face structure board 34 must be taken. Therefore, a lot of work is required for a large number of bolting operations for the lower flanges 31 c and 41 c and a welding operation for the bottom surface configuration plate 34.

Further, there is a problem that the sealing material application work for preventing the liquid leakage takes time and the application work tends to vary, so that liquid leakage is likely to occur.

A sealant such as silicone is injected into the concave groove after being fitted into the concave groove, and the side flanges are opposed to each other and bolted to each other. It is a joining method.

  Further, the invention according to claim 2 for solving the above-mentioned problem is a structure of a joint part for joining a container constituent part having a shape obtained by vertically dividing a box-like container to constitute a liquid-tight tank. In addition, a joining flange is provided on each joining end face of the container constituting portion so as to extend downward on both sides and downward, and the joining face of the joining flange on one side to be joined is passed from the side flange on one side through the lower side flange. A concave groove that is closed at both ends, reaching the side flange on the other side, is formed, and a protrusion that fits into the concave groove is formed on the joint surface of the joint flange on the other side to be joined. It is a joint part structure of an assembly tank such as a coolant tank, in which a sealing material injection port leading to the concave groove is formed in the side flange of the joint flange forming a groove.

  Preferably, a confirmation hole leading to the groove is provided on the inner bottom surface of the container constituting part on the side where the groove is provided, and the groove is a series from one end to the other end. Further, an upper flange that is bolted to each other may be passed to the upper side corresponding portion of the joint surface of each container component.

  The present invention is as described above, and after joining the plurality of container constituent parts to the groove, the sealing material is injected into the groove and the side flanges are bolted to each other. Can be performed by simple work that does not require skill, and sufficient liquid sealing can be performed along with the joining, so that the assembly work of the coolant tank and the like can be performed easily, quickly and efficiently without variation. There is an effect that can be done.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. FIGS. 1 and 2 show a joining method and a joint structure according to the present invention. In FIG. 1 and FIG. 2, reference numerals 1 and 2 denote container constituent parts that constitute a liquid tank such as a coolant tank by butt joining. Each of the container constituting portions 1 and 2 has a box shape that lacks the side surface and the upper surface on the joining end surface side. The container constituent parts 1 and 2 are usually divided in half as described above, but may be divided into three or more parts. In this case, the joining of each part is also in accordance with the method described below.

  The side flanges 3, 3 a (4, 4 a) and the lower flange 5 (6) are usually fixed to the joint end surface of the container constituting part 1 (2) by welding so as to surround the outer end edge. The side flanges 3, 3a (4, 4a) and the lower flange 5 (6) may be integrated or separate.

  Further, if necessary, the upper flange 7 (8) is usually installed by welding at the upper end of the joint component 1 (2) joining end surface. The joint surfaces of the side flanges 3, 3a, the lower flange 5, and the upper flange 7 are flush with each other. Similarly, the joint surfaces of the side flanges 4, 4a, the lower flange 5, and the upper flange 8 are flush. To be.

  A series of U-shaped grooves 9 are formed on the joint surfaces of the side flanges 3, 3 a and the lower flange 5 of one container component 1. Both ends of the concave groove 9 are closed without being opened, but a sealing material such as silicone that extends to the concave grooves 9 on the upper end surfaces of the side flanges 3, 3 a and opens into the concave grooves 9. An inlet 10 is drilled. Further, a plurality of bolt holes 11 are formed outside the concave grooves 9 of the side flanges 3 and 3a. In addition, it is not necessary to form the bolt hole 11 in the lower flange 5. Further, the side flanges 3 and 3a are usually provided with pin holes 12 for allowing a positioning pin 17 to be described later to enter in two places above and below.

  On the joint surface between the side flanges 4, 4 a and the lower flange 6 of the other container component 2, a U-shaped protrusion 14 that fits into the groove 9 is formed. The protrusion 14 is usually a series, but may be divided. The protrusion 14 is formed so that the sealing material filling gap 15 is ensured without being fitted into the groove 9 (see FIG. 4). Further, a bolt hole 16 is formed at a position corresponding to the bolt hole 11 outside the protrusions of the side flanges 4, 4 a, and a positioning pin 17 is protruded at a position corresponding to the pin hole 12.

  In this embodiment, the pin hole 12 is provided on the container component 1 and the positioning pin 17 is provided on the container component 2. However, the opposite is also possible, or the container component 1 Needless to say, one pin hole 12 and one positioning pin 17 may be provided for each of the two.

  Preferably, a confirmation hole 18 that extends to the concave groove 9 and opens is formed in the inner bottom surface of the container constituting portion 1 that forms the concave groove 9. The confirmation hole 18 is usually disposed at an upper intermediate position of the concave groove 9 of the lower flange 6. The confirmation hole 18 serves as a window for confirming that the sealing material is sufficiently injected into the sealing material filling gap 15. Reference numeral 19 denotes a reinforcing rib which is appropriately installed on the bottom surfaces of the container constituent parts 1 and 2.

  In order to assemble the coolant tank and the like by joining the container constituent parts 1 and 2 having the above-described configuration, for example, the container constituent part 2 is moved toward the container constituent part 1 and the protrusion 14 is fitted into the concave groove 9. At that time, by inserting the positioning pin 17 into the pin hole 12, the container component 2 can be aligned with the container component 1, so that the work of fitting the protrusion 14 into the groove 9 is easy. At the same time, alignment of the bolt hole 11 and the bolt hole 16 is also achieved.

  Therefore, the side flanges 3 and 3a and the side flanges 4 and 4a are bolted through the bolt holes 11 and 16, and when the upper flanges 7 and 8 are provided, the portions are similarly bolted. .

  Thereafter, a sealing material is injected from each sealing material inlet 10 to fill the sealing material filling gap 15. Since the confirmation hole 18 is formed at substantially the same position from the sealing material injection ports 10, 10, the sealing material injected from each of the sealing material injection ports 10, 10 collides in the vicinity of the confirmation hole 18. Accordingly, it flows out from the small amount confirmation hole 18. Therefore, the filling state of the sealing material can be grasped by monitoring the confirmation hole 18. Further, since the total capacity of the sealing material filling gap 15 can be known in advance, it is possible to confirm that the sealing material is sufficiently filled by injecting an amount of the sealing material corresponding to the total capacity.

  Thus, when the sealing material filling gap 15 is filled with the sealing material, the joint portions of the container constituting portions 1 and 2 are completely sealed. And since a bolt stop part is located in the outer side of this seal | sticker, it is not necessary to consider the sealing performance of the part.

  As described above, according to the joining method and the joining structure according to the present invention, the assembly work does not require skill, there is no fear of uneven application of the sealing material, and the sealing performance can be surely secured, and the bolting work Since only the side flange is required, the assembling work can be performed easily, quickly and efficiently without variation.
