Description

Technical Field

[0001] The utility model relates to the technical field of glue injection machines, in particular to a glue dispensing auxiliary heating device for a brushless motor steel ring of an airplane model. Background Art

[0002] A small brushless DC motor is a motor with excellent characteristics. It has good mechanical characteristics and adjustment characteristics. It can replace the speed regulation of brushed DC motors, variable frequency motors and asynchronous motors with acceleration and reducers, and can operate at low speed and high power. During the assembly of a small brushless DC motor, glue needs to be injected into the inner wall of the steel ring to fix the steel ring and the upper cover. A common method is to inject air and pressurize the needle filled with colloid to squeeze the colloid from the needle mouth to the inner wall of the steel ring.

[0003] During the glue injection process, there is a certain positive correlation between the fluidity of the colloid and the temperature. The colloid can be heated as a whole to increase its temperature and thus improve its fluidity, which helps to glue the steel rim. However, continuous heating will also have a negative impact on the colloid. Under long-term heating conditions, high temperature can easily change the properties of the colloid. If the colloid cannot be used up in one processing, the overall heating can easily affect the life of the entire tube of colloid and cause waste of consumables. Therefore, an auxiliary heating device for glue dispensing on the steel rim of a brushless motor for a model aircraft is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-3In this embodiment, a brushless motor steel ring dispensing auxiliary heating device for a model aircraft comprises a base 1, an electric lift 2 and a sliding track 9 are fixed on the top of the base 1, the sliding track 9 is T-shaped, and the telescopic end of the electric lift 2 is upward, and the left and right sides of the sliding track 9 are fixed with limit plates fixed to the base 1, and the limit plates can limit the sliding of the sliding plate 11, and the top of the electric lift 2 is fixed with a horizontal plate 3, and the left side of the horizontal plate 3 is fixed with a mechanism plate 4. It should be noted that the cross-section of the mechanism plate 4 is L-shaped, and the L-shaped mechanism plate 4 can provide more component installation surfaces, and the left and right sides of the mechanism plate 4 are respectively fixed with a gas injection pressurizer 6 and an electric control module 5, and the electric control module 5 is connected with other electric energy mechanisms through signals or lines to control the operation of the equipment, and the gas injection end of the gas injection pressurizer 6 is downward, and the bottom of the gas injection pressurizer 6 is fixed with a meshing head 7 that is penetrated by the gas injection end of the gas injection pressurizer 6 and is used to limit the position of the consumables, and the meshing head 7 is adapted to the glue injection mechanism 8 to limit it.

[0032] In addition, the bottom of the mechanism plate 4 is detachably connected to a glue injection mechanism 8 that penetrates through the top thereof and is movably connected to the meshing head 7, the top of the sliding track 9 is slidably connected to a sliding plate 11, and limiting teeth 12 are fixed to the front and rear sides of the bottom of the sliding plate 11, and the cross-section of the limiting teeth 12 is L-shaped. The two limiting teeth 12 fit the outer surface of the sliding track 9, and the top of the sliding plate 11 is respectively fixed with a movable component and a positioning component 19. It should be noted that the movable component includes a fixed frame 13, a mechanism box 14, a motor 15, a rotating shaft 16, a fixed seat 17 and two fixed teeth 18.

[0033] It should also be noted that the motor 15 is fixed at the bottom of the inner cavity of the mechanism box 14, and the output shaft of the motor 15 is facing upward, the rotating shaft 16 is fixed to the output shaft of the motor 15 and passes through the top of the fixed frame 13, the fixed seat 17 is fixed to the top of the rotating shaft 16, and the two fixed teeth 18 are fixed to the top of the fixed seat 17 and are symmetrically distributed.

[0034] It should be understood that a plurality of ventilation holes are provided on both sides of the mechanism box 14. A large amount of heat will be generated during operation. If the heat is not dissipated, the mechanism will operate at high temperature. This will reduce the service life of the mechanism in the long run.

It should be noted that the positioning component 19 includes a positioning box 1901, a positioning rod 1902, a pulling rod 1903, a grip ball 1904 and a spring 1905. The positioning box 1901 is fixed on the top of the sliding plate 11, and the positioning rod 1902 is slidably connected to the inner surface of the positioning box 1901 and penetrates into the interior of the sliding track 9, so that the positioning rod 1902 slides into or out of the inner cavity of the positioning box 1901, changing the total length of the two, and squeezing the spring 1905, so that the sliding of the sliding plate 11 is limited by the locking connection between the positioning rod 1902 and the sliding track 9.

[0036] It should be further explained that a plurality of positioning grooves 10 are provided on the top of the sliding rail 9 and match the positioning rod 1902 . The positioning rod 1902 passes through the positioning grooves 10 . The sliding rail 9 is clamped with the positioning rod 1902 through the positioning grooves 10 to limit the sliding of the sliding plate 11 .

[0037] It should also be noted that the pulling rod 1903 is fixed at the top of the positioning rod 1902 and passes through the right side of the positioning box 1901. The cross-section of the pulling rod 1903 is L-shaped. The mechanism is driven to move upward by the pulling rod 1903. The gripping ball 1904 is fixed at the top of the pulling rod 1903. The gripping ball 1904 can increase the gripping points to facilitate the operator's processing. The spring 1905 is fixed at the top of the pulling rod 1903 and fixed to the positioning box 1901. The spring 1905 is located in the inner cavity of the positioning box 1901, and the elastic force of the spring 1905 reacts to the component, so that it can automatically restore the limit.

[0038] During operation, the steel ring to be processed is positioned by the movable assembly and can be driven to rotate, and the inside of the glue injection mechanism 8 is pressurized by the gas injection pressurizer 6 to perform rotational glue injection on the inner surface of the steel ring.

[0039] See also Figure 4In order to heat the colloid in the needle nozzle part separately, the glue injection mechanism 8 in this embodiment includes a mounting tube 801, a glue bottle 802, a glue injection needle nozzle 803, an electric heating wire 804 and an insulating glue layer 805. The mounting tube 801 is detachably connected to the bottom of the mechanism plate 4 and penetrates to its top. The glue bottle 802 is movably connected to the top of the mounting tube 801. A glue outlet is provided at the bottom of the glue bottle 802. The gas injection end of the gas injection pressurizing machine 6 penetrates into the inside of the glue bottle 802, and the inside of the glue bottle 802 can be inflated and pressurized through the gas injection end. The inside of the glue bottle 802 is filled with colloid. The inside of the glue bottle 802 is inflated by the gas injection pressurizing machine 6 to increase the internal pressure of the glue bottle 802, and the colloid in the glue bottle 802 is squeezed out.

[0040] In addition, the glue injection needle nozzle 803 is fixed at the bottom of the installation tube 801, the glue injection needle nozzle 803 is bent toward the inner wall of the steel ring, and the glue injection needle nozzle 803 is funnel-shaped. The funnel-shaped glue injection needle nozzle 803 is convenient for the colloid to flow downward. The tip of the glue injection needle nozzle 803 is provided with an eccentrically arranged glue injection port, and the glue injection port can make the colloid flow out. The electric heating wire 804 is fixed on the outer surface of the glue injection needle nozzle 803, and the electric heating wire 804 is used to heat the colloid in the area of ​​the glue injection needle nozzle 803. The electric heating wire 804 is spiral-shaped, and the electric heating wire 804 heats the colloid in the area of ​​the glue injection needle nozzle 803 to melt the local glue, which will not affect the life of the whole tube of colloid. The insulating glue layer 805 is fixed on the outer surface of the glue injection needle nozzle 803 and covers the electric heating wire 804. The insulating glue layer 805 can protect the electric heating wire 804 from the influence of the external environment, extend its service life, and prevent its heat from scalding the processor.

[0041] In general, the inside of the glue bottle 802 is inflated by the gas injection pressurizing machine 6 to increase the internal pressure of the glue bottle 802, and the glue inside the glue bottle 802 is squeezed into the glue injection needle nozzle 803. The colloid inside the glue injection needle nozzle 803 is heated separately by the spiral electric heating wire 804 to enhance its fluidity so that it can flow out smoothly from the glue injection port.

[0042] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0043] The working principle of the above embodiment is:

[0044] (1) When making adjustments, the glue bottle 802 is a consumable material. It is purchased and movably connected to the inner surface of the mounting tube 801, and the gas injection end of the gas injection pressurizer 6 is passed through the inside of the glue bottle 802. When moving to the bottom of the colloid, the steel ring is inserted between the two fixed teeth 18, the gripping ball 1904 is held, and the positioning rod 1902 is driven to move upward by pulling the rod 1903, so that it rises and leaves the current positioning groove 10, and at the same time, the spring 1905 is squeezed to make it elastically deformed and continuously accumulate elastic force. At this time, the positioning rod 1902 no longer restricts the sliding of the sliding plate 11, and the sliding plate 11 is slid to the right so that the steel ring is located directly below the glue injection needle nozzle 803, and the gripping ball 1904 is released, so that the positioning rod 1902 moves downward under the elastic force of the spring 1905 and is stuck in the corresponding positioning groove 10, and the position of the sliding plate 11 is redefined;

[0045] (2) When injecting glue, the electric lift 2 is started and retracted downward, so that the glue injection nozzle 803 is moved to a first preset height, and the glue bottle 802 is inflated by the gas injection pressurizer 6 to increase the internal pressure of the glue bottle 802, so that the glue in the glue bottle 802 is squeezed into the glue injection nozzle 803, and the spiral electric heating wire 804 is used to heat the glue in the glue injection nozzle 803 separately to enhance its fluidity so that it can flow out of the glue injection port smoothly. At the same time, the motor 15 is driven to rotate the fixed seat 17 so that the glue can flow out. The colloid forms the first glue mark on the inner wall of the steel ring, and then the electric lifter 2 is started again and retracted downward, so that the glue injection nozzle 803 reaches the second preset height, and the fixed seat 17 rotates and pressurizes the glue to form a second glue mark on the inner wall of the steel ring. The motor 15 stops running, and the electric lifter 2 reverses to drive the glue injection nozzle 803 to reset upward. The colloid inside the glue injection nozzle 803 is heated separately by the electric heating wire 804, which can prevent the colloid in the whole bottle from deteriorating, will not affect the life of the whole tube of colloid, and can enhance its fluidity, with a good processing effect.
