Description

Technical Field

[0001] This invention belongs to the field of core skeleton assembly technology for tubular products, specifically relating to a method and apparatus for assembling and positioning the core skeleton of stainless steel tubular products. Background Technology

[0002] The current limitations and complexities in assembling the core frame of stainless steel tubular products mainly lie in the use of limiting blocks for layer-by-layer positioning. The ease of assembling the heat dissipation tubes in tubular products depends on the parallelism and flatness of the baffles during assembly; even slight misalignment of the baffles can prevent the heat dissipation tubes from passing through. Existing core frame assembly technology for tubular products cannot guarantee the parallelism and flatness of the baffles and core end plates.

[0003] Currently, the assembly of the core skeleton for tubular products typically faces the following two problems:

[0004] 1. Poor parallelism and flatness of the baffle and core end plate;

[0005] 2. The core frame is misaligned.

[0006] In summary, the existing core frame assembly technology for tube-type products has many defects, which increases the difficulty of heat pipe assembly. In particular, as the volume of the core frame continues to increase, these defects lead to more and more core assembly problems. Summary of the Invention

[0007] In view of the problems existing in the background art, the present invention aims to provide a tube-type core skeleton assembly and positioning device and method, which solves the misalignment problem caused by the inability to guarantee the parallelism and flatness of the baffle plate and core end plate during the assembly of the current tube-type core skeleton, improves the assembly efficiency and quality of the tube-type core skeleton, and reduces the assembly difficulty.

[0008] To solve the above problems, the present invention adopts the following solution:

[0009] A tubular core skeleton assembly and positioning device, comprising,

[0010] A base, the upper surface of which includes a boss;

[0011] The bracket has one end detachably connected to the upper surface of the base, and the two brackets are located on both sides of the boss and are symmetrically arranged about the center of the boss. Each of the two brackets has a positioning plate slot at the same vertical height from the upper surface of the boss.

[0012] The first positioning plate is inserted into the positioning plate socket of the bracket. The surface of the first positioning plate is provided with a first baffle positioning groove. The inner contour shape of the first baffle positioning groove includes a portion of the outer contour shape features of the baffle.

[0013] The second positioning plate is inserted into the positioning plate socket of the bracket. The surface of the second positioning plate is provided with a second baffle positioning groove. The inner contour shape of the second baffle positioning groove includes a portion of the outer contour shape features of the baffle, and the portion of the outer contour shape features is different from the outer contour shape features of the corresponding baffle on the first baffle positioning groove.

[0014] The third positioning plate is located at the upper end of the two supports and has multiple positioning holes.

[0015] Furthermore, the upper end of the bracket has a positioning groove, and the two ends of the third positioning plate are respectively placed in the positioning grooves of the two brackets.

[0016] Furthermore, both the first positioning plate and the second positioning plate include a handle segment, a limiting segment, and a positioning segment connected in sequence. The width of the limiting segment is greater than the width of the positioning plate socket. The positioning segment is provided with a first baffle positioning groove or a second baffle positioning groove. The width of the positioning segment is equal to the width of the positioning plate socket. The maximum thickness of the positioning segment is equal to the thickness of the positioning plate socket. The sum of the lengths of the positioning segments of the first positioning plate and the second positioning plate is less than the distance between the two brackets.

[0017] Furthermore, one end of the bracket is connected to the base by screws and locating pins.

[0018] A method for assembling and positioning a tubular core skeleton, employing the aforementioned assembly and positioning device, includes the following steps:

[0019] Step 1: Insert the first positioning plate and the second positioning plate into the positioning plate slots of the bracket. Insert one first positioning plate and one second positioning plate into the positioning plate slots at the same vertical height. Alternately insert the first positioning plate and the second positioning plate into adjacent positioning plate slots on the same bracket. Place the third positioning plate at the top of the bracket.

[0020] Step 2: Place the core end plate of the tubular core onto the protrusion of the base;

[0021] Step 3: Place the baffle plates sequentially into the first and second positioning plates at the same vertical height, ensuring that the baffle plates are completely positioned in the first and second baffle plate positioning grooves.

[0022] Step 4: Pass the positioning rod through the positioning holes on the third positioning plate, the positioning holes on the baffle plate, and the positioning holes on the core end plate in sequence.

[0023] Step 5: Spot weld the positioning rod, baffle plate, and core end plate.

[0024] Furthermore, in step three, the baffles are placed sequentially from top to bottom.

[0025] Furthermore, in step five, argon arc welding is used to spot weld the positioning rod, the baffle plate, and the core end plate.

[0026] The assembly positioning device of the present invention has the following features:

[0027] (1) The parallelism of the baffle plate and the core end plate is ensured by the height dimension of the positioning plate socket on the bracket. The positional relationship of the baffle plate and the core end plate is transferred to the machining accuracy of the positioning plate socket on the bracket. When the multiple positioning plate sockets on a pair of brackets are machined, the spatial positional relationship of the multiple positioning plate sockets is determined, which can solve the subsequent parallelism problem. It is not necessary to place the limiting blocks layer by layer as in the existing assembly method, thus avoiding the parallelism error between different layers caused by the random placement of the limiting blocks.

[0028] (2) The flatness of the baffle plate is ensured by the flatness of the positioning plate socket on the bracket, and the flatness of the core end plate is ensured by the flatness of the base boss. Since the positioning plate socket and the base boss can be machined to obtain a high degree of flatness, the flatness assembly requirements of the baffle plate and the core end plate are fully met.

[0029] (3) The baffle positioning grooves on the first positioning plate and the second positioning plate each contain a portion of the outer contour features of the baffle plate. The purpose is to enable quick and accurate positioning of the baffle plate while facilitating the disassembly of the first positioning plate and the second positioning plate. That is, the baffle positioning grooves take part of the contour information of the baffle plate to avoid the positioning holes on the baffle plate (because the complete baffle plate contour will include the positioning holes). Thus, the first positioning plate and the second positioning plate can be quickly pulled out from the brackets on both sides after the positioning rod passes through the baffle plate (relative to the method of only one positioning plate, it is easier to pull out, because if there is only one positioning plate, the length is too long, and it will be very difficult to pull out the bracket and it is easy to get stuck). It is not necessary to spend a lot of time to adjust the baffle plate layer by layer by combining multiple limit blocks as in the traditional assembly method (it can be directly put into the baffle positioning groove), nor is it necessary to spend a lot of time to remove the limit blocks layer by layer, thus reducing the assembly difficulty.

[0030] (4) For the assembly of a large core frame, in order to avoid bending of the end of the positioning plate due to the excessive length of the first and second positioning plates, a design method was adopted in which the sum of the length of the positioning section of the first positioning plate and the length of the positioning section of the second positioning plate is less than the distance between the two brackets. A gap is left between the two positioning plates to ensure that the length of the positioning plate is reduced and the bending effect of the positioning plate is reduced while meeting the positioning requirements.

[0031] (5) The first and second positioning plates in the multiple positioning plate slots on the same side bracket are inserted alternately to ensure that the deformation of the brackets on both sides is symmetrical about the boss (because the center of gravity of the first and second positioning plates are different. If the same type of positioning plate is installed on the straight frame on the same side, the bending deformation of the brackets on both sides will be significantly different, resulting in a greater height difference in the positioning plate slots with higher heights. This problem cannot be ignored, especially for core skeletons with large dimensions).

[0032] (6) The first and second positioning plates are easy to operate through the handle section. The limit section can quickly find the extreme position after the positioning plate is inserted. By matching the width and thickness of the positioning section with the width and thickness of the positioning plate, the positions of the first and second positioning plates can be accurately positioned to meet the parallelism requirements. (7) The spatial position information of the baffle plate is completely fixed by the machining of the bracket and the base boss, avoiding the problem of core skeleton skew caused by the randomness of the traditional limit block assembly, which greatly improves the assembly efficiency, and also improves the assembly quality and precision.

[0033] Compared with the prior art, the assembly and positioning device of the present invention can ensure the parallelism and flatness between the baffles when assembling the tube-type core skeleton. The entire assembly process is simple and easy to operate, and avoids the heat dissipation tubes being unable to pass through the baffles due to misalignment of the baffles.
