In order to solve the problem, the utility model provides a heat exchanger welding frock when having solved the relevant subassembly welding of heat exchanger casing and dabber, the unable problem of guaranteeing of concentricity of the relative position degree of casing and dabber trompil, casing and dabber.
The utility model adopts the technical proposal that: the utility model provides a heat exchanger welding frock, the base processing has the mounting hole of tip V type piece and middle V type piece, is connected tip V type piece and middle V type piece with the base through the bolt, and tip V type piece superstructure is the V profile, and the bottom of V profile is equipped with the dabber locating pin, and middle V type piece superstructure is the V profile, and the bottom of V profile is equipped with the casing locating pin.
Further optimizing, when the diameter of the V-shaped surface corresponding to the inscribed circle of the end V-shaped block is the diameter of the mandrel and the diameter of the V-shaped surface corresponding to the inscribed circle of the middle V-shaped block is the diameter of the shell, the V-shaped surfaces of the end V-shaped block and the middle V-shaped block are corresponding to the inscribed circle and are concentric circles, and therefore the heat exchanger is guaranteed to be kept horizontal when placed on a tool.
Further optimize, the quantity of tip V type piece is 2, is located the both ends of base respectively, and the distance between two tip V type pieces equals the distance in dabber both ends hole, and the distance in two dabber locating pin centre of a circle equals the distance in the centre of a circle in dabber both ends hole promptly.
Further optimize, the quantity of middle V type piece is 2, is located the inboard of two tip V type pieces respectively, and the distance between two middle V type pieces equals the distance in casing both ends hole, and the distance in two casing locating pin centre of a circle equals the distance in the centre of a circle in casing both ends hole promptly.
Further optimizing, the diameter of dabber locating pin is slightly less than the aperture on the dabber, and the diameter of casing locating pin is slightly less than the aperture on the casing.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use through using this kind of hoist, guarantees the concentricity of the relative position degree of casing and dabber trompil, casing and dabber, improves heat exchanger manufacturing accuracy, production efficiency, reduction in production cost, alleviates operating personnel's intensity of labour.

Detailed Description
The technology of the present invention will be further specifically explained with reference to the drawings.
As shown in fig. 1, the base 1 is provided with mounting holes for the end V-shaped block 3 and the middle V-shaped block 2, the end V-shaped block 3 and the middle V-shaped block 2 are connected with the base 1 through bolts, as shown in fig. 3, the upper structure of the end V-shaped block 3 is a V-shaped surface, the bottom of the V-shaped surface is provided with a mandrel positioning pin 4, as shown in fig. 4, the upper structure of the middle V-shaped block 2 is a V-shaped surface, and the bottom of the V-shaped surface is provided with a housing positioning pin 5. When the diameter of the V-shaped surface corresponding to the inscribed circle of the end V-shaped block 3 is the diameter of the mandrel, and the diameter of the V-shaped surface corresponding to the inscribed circle of the middle V-shaped block 2 is the diameter of the shell, the corresponding inscribed circles of the V-shaped surfaces of the end V-shaped block 3 and the middle V-shaped block 2 are concentric circles, namely the circle center of the concentric circle coincides with the axis of the heat exchanger, so that the heat exchanger is ensured to be kept horizontal when being placed on a tool.
As shown in fig. 1 and 2, the number of the end V-shaped blocks 3 is 2, and the end V-shaped blocks are respectively located at two ends of the base 1, and the distance between the two end V-shaped blocks 3 is equal to the distance between the holes at two ends of the mandrel, that is, the distance between the centers of circles of the two mandrel positioning pins 4 is equal to the distance between the centers of circles of the holes at two ends of the mandrel. The number of the middle V-shaped blocks 2 is 2, the middle V-shaped blocks are respectively positioned at the inner sides of the two end V-shaped blocks 3, the distance between the two middle V-shaped blocks 2 is equal to the distance between the holes at the two ends of the shell, namely the distance between the circle centers of the two shell positioning pins 5 is equal to the distance between the circle centers of the holes at the two ends of the shell. The diameter of the mandrel positioning pin 4 is slightly smaller than the aperture of the mandrel, and the diameter of the shell positioning pin 5 is slightly smaller than the aperture of the shell. When the heat exchanger is placed on the tool, exactly four positioning pins are arranged in the holes corresponding to the shell and the core shaft, so that the heat exchanger is stably placed on the tool.
When the heat exchanger welding tool is used, related components such as a shell, a mandrel and the like of the heat exchanger are preassembled and then placed on the welding tool, a shell hole is aligned with a shell positioning pin 5 of the middle V-shaped block 2, and the mandrel hole is inserted into a positioning pin after being aligned with a mandrel positioning pin 4 of the end V-shaped block 3; the heat exchanger shell and the mandrel are naturally attached to the V-shaped surfaces of the middle V-shaped block 2 and the end V-shaped block 3, and then welding operation can be carried out.
