Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly, and more specifically, to an anti-loosening marking spray gun. Background Technology

[0002] Bolted connections are widely used in various equipment and structures during mechanical assembly. To ensure the reliability of bolted connections and prevent loosening due to vibration or other reasons, anti-loosening marks are usually applied after the bolts are tightened. The quality of the anti-loosening marks directly affects the efficiency of bolted connection inspection and maintenance.

[0003] In the field of mechanical assembly, the reliability of bolted connections is crucial, and accurate application of anti-loosening marks is one of the effective means of determining whether bolts are loose. Currently, conventional application methods mainly include manual and electric application. Traditional manual anti-loosening mark application relies on manual hand-held marking pens, depending on the operator's experience and physical strength. This method is not only slow and inefficient, but also makes it difficult to guarantee the uniformity and accuracy of the marks, failing to meet the needs of large-scale assembly production. Currently, there are some electric anti-loosening mark application devices on the market. Their basic principle is to use an electric drive device to apply the marking material (such as paint). However, these devices generally have the following problems: First, their structure is complex. Some electric devices contain multiple transmission components and control systems, resulting in large size, heavy weight, inconvenient operation, and high maintenance costs. Second, the application accuracy is limited. Due to the lack of precise control mechanisms in existing electric devices, the width and position of the applied marks are difficult to control precisely, leading to instability and affecting the accuracy and reliability of the anti-loosening marks, thus affecting the inspection effect of bolt connections. Third, they lack versatility; existing equipment has poor adaptability to bolts of different specifications. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an anti-loosening marking gun that can efficiently and accurately apply anti-loosening markings and has strong versatility.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] This utility model relates to an anti-loosening marking spray gun, comprising a housing, an outer casing containing a glue tank, a needle at one end of the glue tank, and a reciprocating piston inside the other end; the housing contains an electric push rod motor for driving the piston, a battery for power supply, and a motor controller for controlling the operation of the electric push rod motor; the outer wall of the housing contains a charging port for charging the battery, a switch for controlling power on / off, and a start button for controlling the spraying operation.

[0007] Furthermore, the battery input terminal is connected to the charging port; the battery output terminal is connected to the power input terminal of the motor controller, and a switch is connected between the two; the control signal output terminal of the motor controller is connected to the electric push rod motor, and a start button is connected between the two.

[0008] Furthermore, the housing is configured as a hollow structure with a handle, the battery is installed inside the handle portion of the housing, the start button is located on the outer wall of the front end of the handle portion of the housing, and the electric push rod motor is located at the front end of the housing.

[0009] Furthermore, the electric push rod motor is a high-precision stepper motor, and its output shaft is connected to the piston inside the rubber barrel.

[0010] Compared with the prior art, the beneficial effects of the technical solution of this utility model are:

[0011] (1) High coating efficiency: It adopts a simple and efficient electric push rod motor drive, which has a fast coating speed and is easy to operate, and can meet the needs of large-scale assembly production.

[0012] (2) High coating accuracy: A high-precision stepper motor is used as the power source, and the motor controller and piston design are used to achieve precise control of the motor. The width and position of the coated marking line are stable, ensuring that the piston moves smoothly and the speed is controllable in the glue bucket. This achieves uniform and quantitative coating of glue, improves the coating accuracy and consistency of the anti-loosening mark, and improves the inspection effect of bolt connection.

[0013] (3) Compact structure: This utility model is mainly divided into two parts, one part is a rubber bucket and the other part is a shell. The electric push rod motor, battery, motor controller and other components are integrated into a compact shell. Through reasonable layout and connection method, the miniaturization and lightweight of the equipment are realized, which is convenient for operators to operate by hand. At the same time, the stability and reliability of the equipment are guaranteed and the maintenance cost is low.

[0026] Preferably, the housing 1 can be configured as a hollow structure with a handle, the battery 6 is installed inside the handle portion of the housing 1, the start button 10 is located on the outer front wall of the handle portion of the housing 1, and the electric push rod motor 2 is located at the front end inside the housing 1. All components are integrated into a compact housing through a reasonable structural design, facilitating handheld operation by the operator.

[0027] The operation process of this utility model:

[0028] ①Preparation: Fill glue container 3 with glue, ensuring it is full. Check the battery power of battery 6; if low, charge battery 6 through charging port 8.

[0029] ② Start the equipment: Press switch 9 to power on the equipment, and the motor controller 7 will enter standby mode.

[0030] ③ Application Operation: The operator holds the housing 1, aligns the needle 5 with the application position on the bolt, presses the start button 10, and the electric push rod motor 2 drives the piston 4 to move. The glue is evenly applied to the bolt through the needle 5 to form an anti-loosening mark.

[0031] ④ Stop operation: Release the start button 10, the electric push rod motor 2 stops running, and the coating is completed. The operator can move this utility model equipment to perform the coating operation on the next bolt.
