Description
Technical Field
The utility model relates to an auxiliary drilling tool for a spiral baffle plate, which can be used for drilling the spiral baffle plate on a drilling machine and can ensure the requirements of accuracy of machining, assembly precision and the like.
Background
The spiral baffle heat exchanger adopts a spiral plate which is arranged at a certain angle with the axis of the shell as a baffle plate. The medium is spirally pushed to flow in the shell, so that a higher heat transfer effect is realized under the condition of smaller pump function consumption. The method is characterized in that: the heat transfer coefficient is higher; the shell side flow resistance is small, and no stagnation area exists; is not easy to deposit dirt. The maintenance period is prolonged, and the maintenance cost is reduced. Is suitable for more viscous medium. But the key in helical baffle bundles is the manufacture and assembly of the helical baffles. Because the spiral baffle plates are not parallel to the tube plates but form an included angle with the tube plates, the spiral of the spiral baffle plates is obliquely distributed by a certain angle by each fan-shaped baffle plate, and the processing process of the spiral baffle plates is more complicated than that of common arched baffle plates. Because the angle deviation is not easy to grasp, the boring and milling machine can be used for drilling the spiral baffle plate, but the machining efficiency is low and the machining cost is high. Therefore, special manufacturing tools are required to be manufactured aiming at a common drilling machine, so that the machining efficiency is high, the machining cost is low, and the machining accuracy and the assembly precision are guaranteed.
Disclosure of Invention
The utility model provides an auxiliary drilling tool for a spiral baffle plate, which aims to solve the technical problems that the processing and positioning are difficult and the processing efficiency is low due to the lack of a corresponding positioning tool when the spiral baffle plate is drilled at present.
The utility model is realized by adopting the following technical scheme: a spiral baffle drilling auxiliary manufacturing tool comprises a first template and a second template; the first template is in a fan-shaped structure in the front view direction, is in a right trapezoid structure or a right triangle structure with a narrow upper part and a wide lower part in the side view direction, a plurality of fastening holes penetrating through the front and the rear of the first template are formed in the front face of the first template around the circumference of the fan-shaped structure, and a plurality of guide holes penetrating through the front and the rear of the first template are formed in the area surrounded by the fastening holes;
the second template is in a sector structure with the same shape as the first template in the front view direction, is in a right trapezoid structure or a right triangle structure with the upper part wide and the lower part narrow in the side view direction, and the bevel edge of the second template is the same as the bevel edge of the first template in angle; the front surface of the second template surrounds the circumference of the fan-shaped structure and is provided with a plurality of fastening holes penetrating through the front and rear surfaces of the second template, and the second template is provided with a plurality of guide holes penetrating through the front and rear surfaces of the second template in the area surrounded by the fastening holes;
the fastening holes and the guide holes on the first template and the second template are uniformly and correspondingly arranged; the first and second templates can be butted with each other with respective inclined surfaces, and are connected by a fastening bolt passing through the fastening hole and a nut matched with the fastening bolt.
The inclined planes of the first template and the second template are consistent with the inclined angle of the baffle plate to be processed. When the fixture is specifically applied, one or more baffle plates are placed between the first template and the second template, fastening bolts and nuts are used for fastening and fixing, and the fixture clamped by the baffle plates is of a rectangular structure as a whole, so that the fixture is convenient to clamp and position. Because the inclination angle of the baffle plate is positioned by the first template and the second template, the drilling processing of the baffle plate on the drilling machine under the inclined condition is ensured, and the drilling effect is ensured.
The utility model aims to provide an auxiliary manufacturing tool for drilling of a spiral baffle plate, which can ensure that the drilling of a drill bit is not deviated when the deep hole drill bit is used. A spiral baffle plate heat exchanger needs to use dozens of baffle plates, the baffle plates are manufactured by processing in batches, and the tool can ensure the assembly precision requirement of drilling processing in batches. And the tool can be used for double-sided processing, so that overlong drill bits are avoided, and the processing cost is reduced.

Detailed Description
Example 1
As shown in fig. 1-4, a spiral baffle manufacturing tool consists of a first template 1, a second template 2, a fastening bolt 6 and a nut 7; the first template 1 is in a fan-shaped structure in the front view direction, the first template 1 is in a right trapezoid structure or a right triangle structure with a narrow upper part and a wide lower part in the side view direction, a plurality of fastening holes 3 penetrating through the front and the back of the first template 1 are formed in the front face of the first template 1 around the circumference of the fan-shaped structure, and a plurality of guide holes 4 penetrating through the front and the back of the first template 1 are formed in the area surrounded by the fastening holes 3 of the first template 1;
the second template 2 has a fan-shaped structure with the same shape as the first template 1 in the front view direction, the second template 2 has a right trapezoid structure or a right triangle structure with the upper part being wide and the lower part being narrow in the side view direction, and the bevel edge of the second template 2 has the same angle with the bevel edge of the first template 1 (but is just upside down); the front surface of the second template 2 surrounds the circumference of the fan-shaped structure and is provided with a plurality of fastening holes 3 which penetrate through the front and rear surfaces of the second template 2, and the second template 2 is provided with a plurality of guide holes 4 which penetrate through the front and rear surfaces of the second template 2 in the area surrounded by the fastening holes 3;
the fastening holes 3 and the guide holes 4 on the first template and the second template are uniformly and correspondingly arranged; the first and second templates can be butted with each other with respective inclined planes (hypotenuses of right trapezoid or right triangle) and connected by a fastening bolt 6 passing through the fastening hole and a nut 7 matching the fastening bolt 6.
As shown in fig. 1 and 3, the first and second templates of the present utility model have the same structure in the front view direction, and the fastening holes and the guide holes are arranged in the same manner; however, as can be seen from fig. 2 and 4, the first and second templates are different from each other in side view, that is, the inclined plane of the first template is located on the front side, the inclined plane of the second template is located on the rear side, and the inclined planes of the two templates have the same angle, but are inverted upside down, so that they can be spliced into a rectangle.
As shown in fig. 5, in a specific application of the present utility model, one or more baffles are sandwiched between two templates by a first and a second templates, and the two templates are fixed together by fastening bolts and nuts, thereby clamping the baffles. Because the first template and the second template form a cube after being butted, the clamping is more convenient (the first template and the second template after being butted are generally required to be positioned by clamping jaws on a machine tool), the drilling operation on the baffle plate can be effectively ensured, and the drilling precision is also ensured.
During processing, the workpiece of the baffle plate can be preformed, the size of the workpiece is smaller than that of the first template and the second template, and then the workpiece is clamped between the two templates; the baffle plate can be processed into a larger workpiece (the same as or larger than the first template and the second template), and fastening holes corresponding to the first template and the second template are processed on the workpiece, so that the baffle plate can be more stable in clamping. After drilling, the redundant part of the baffle plate is cut off.
Example 2
The first template and the second template are right trapezoid structures in side view directions; the axial directions of the fastening hole 3 and the guide hole 4 are perpendicular to the right-angle side of the right trapezoid.
