Description

Heat exchange tube head grinding device

technical field

The utility model relates to a heat exchange tube head grinding device, which belongs to the technical field of machinery.

Background technique

In the prior art, people usually use a grinder to grind the tube head of the heat exchange tube, and the heat exchange tube is hand-held to grind the tube head. This method not only consumes manpower and material resources, but also has large errors during the manual operation. It is also easy for the type of work to polish the workpiece completely substandard and become waste. Moreover, the manual operation of daily processing also wastes time and affects production efficiency.

Utility model content

The utility model provides a heat exchange tube head grinding device, which does not need to use manpower to polish the heat exchange tube head, only needs to place the heat exchange tube on a special rack, start the motor, and the heat exchange tube head can be The two ends of the machine are polished at the same time, which solves the problem of wasting manpower and time, and the grinding accuracy is further improved to ensure product quality.

In order to solve the above technical problems, the utility model provides the following technical solutions: a grinding device for the head of a heat exchange tube. The motor and heat exchange tube placement frame outside the impeller, the rotation direction of the two impellers at the head and tail is opposite, the heat exchange tube is on the same side of the center line of the two impellers, and the end surface of the heat exchange tube head is just inside the two impellers end face.

Further, the bottom of the motor is connected to the motor frame, the bottom of the motor frame is fixed with a motor base, the motor frame is made of a channel steel buckled upside down on a square iron plate, the channel steel and the iron plate are welded, and the square iron plate and the motor The bases are connected by bolts.

Further, the shape of the opening on the square iron plate is an oblong hole, and the number of the oblong holes is four, and each oblong hole arranged on the square iron plate is connected by a set of bolts on average, and the distance between the two bolts on each side is Center distance between two oblong holes.

Further, a base is provided at the bottom of the heat exchange tube placement frame, a backing plate is provided at the center below the base, and is connected to the base, and several supports are connected to the top of the base.

Further, the top of the support is provided with two semicircular grooves, and a groove for placing a step at the head of the heat exchange tube is opened.

The heat exchange tube head grinding device involved in the utility model has different grinding directions at both ends, which makes the heat exchange tube more stable in the heat exchange tube placement rack and ensures the grinding quality. The utility model has the advantages of simple structure, low cost and convenient use, and brings beneficial effects of saving time, cost and manpower for grinding the head of the heat exchange tube in the factory.

Description of drawings

Fig. 1 is a structural schematic diagram of a heat exchange tube head grinding device of the present invention;

Fig. 2 is the structural diagram of the motor frame and the motor base of the present utility model;

Fig. 3 is a three-dimensional view of the motor frame and the motor base of the present invention;

Fig. 4 is a schematic diagram of the three-dimensional structure of the support of the utility model.

Detailed ways

As shown in Fig. 1, described grinding device comprises motor 1, impeller 2 and auxiliary device, as shown in Fig. 2, Fig. 3 and Fig. 4, auxiliary device comprises motor frame 7, motor base 6 and the support of supporting heat exchange tube Seat 3, base 5 and backing plate 4.

The structure of the grinding device is that the motor 1 and the impeller 2 are connected by fasteners, and the impeller 2 is driven by the motor 1 to rotate. The characteristic of this structure is that the impeller 2 is assembled on the motor shaft through a shaft sleeve, a gasket, etc., and is fastened by bolts. In addition, in order to ensure the normal rotation of the heat exchange tube 8, one of the two motors is for forward rotation and the other is for reverse rotation. Therefore, the direction of rotation of the corresponding threaded holes for fixing the motor is also reversed.

After the two bearings are assembled with the shaft and bushing respectively, the bushing is then spot-welded on the support 3, and the heat exchange tube is placed between the two bearings. During grinding, the heat exchange tube rotates to drive the inner ring of the bearing to roll, and then it can be fixed. The heat exchange tubes can also realize the free rotation of the heat exchange tubes, and the number of heat exchange tube supports 3 depends on the length of the heat exchange tubes.

The specific implementation described in the utility model does not constitute a limitation to the scope of the application, and within the spirit and principles of the utility model, any amendments, equivalent replacements and improvements that professionals in the field can make should include Within the protection scope of the present utility model.
