Description

Technical Field

[0001] This utility model relates to the field of automatic tooling technology, and in particular to an automatic locking device and unit for threaded fasteners. Background Technology

[0002] Threaded connections, as a widely used mechanical locking method, are mainly used in industrial production to achieve reliable connection and fixation between two or more components. With the increasing demands for assembly efficiency in modern manufacturing, various automated locking devices have gradually emerged in the market. These devices, through advanced automated control systems, can automatically tighten threaded fasteners, thereby significantly improving the production efficiency of assembly operations.

[0003] However, most mainstream automatic locking devices currently employ a top-down design, where the locking actuator, fasteners, and the product to be connected are arranged sequentially from top to bottom. In practical use, this design has a significant limitation: the installation height of the locking actuator must be greater than the total height of the product and fasteners stacked together to ensure the automatic locking device can perform the fastening operation correctly. This height restriction significantly limits the application scenarios of such automatic locking devices, especially in environments with limited space, where they often prove ineffective. Utility Model Content

[0004] This utility model provides an automatic locking device and unit, which adopts an inverted configuration scheme, eliminating the need to consider the relationship between the installation height of the locking actuator and the total height of the product and fasteners stacked together, thus expanding its application scope.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic locking device includes a base, a drive motor fixedly mounted on the base, a locking block mounted on the output end of the drive motor, the locking block being connected to a component to be locked, and a fixing block on the base, the fixing block having a fixing groove for placing and restricting the rotation of the product, and the product being movable along the axial direction of the fixing groove.

[0007] The drive motor, locking block, and fixing block are arranged vertically from bottom to top, and the drive motor drives the locking block to tighten the parts to be locked.

[0008] Furthermore, it also includes a control component, which includes a controller and a sensor electrically connected to the controller. The controller is connected to the drive motor, and the sensing end of the sensor is located in a fixed slot to monitor whether the product is installed in place.

[0009] The controller starts the drive motor based on the monitoring signals from the sensors to tighten the parts to be locked.

[0010] Furthermore, the sensor is a through-beam fiber optic sensor.

[0011] Furthermore, the drive motor is a servo motor with adjustable torque. The controller shuts down the drive motor based on whether the torque of the servo motor reaches the preset torque value; or, the controller shuts down the drive motor based on whether the start time of the servo motor reaches the preset running time.

[0012] Furthermore, the locking block is provided with a groove that adapts to the shape of the part to be locked. The groove can be connected to the part to be locked to drive the part to be locked to tighten.

[0013] Furthermore, the base includes a support plate assembly and an upright plate connected to one side of the support plate assembly. The drive motor is fixedly connected to the support plate assembly. The support plate assembly is provided with a clearance hole for the output end of the drive motor to pass through. A fixing block is provided at the end of the upright plate away from the support plate assembly. A locking block is provided in the space between the fixing block and the support plate assembly.

[0014] A unit includes a machine base and an automatic locking device as described above. The machine base is equipped with a power supply and a switch for turning the power supply on and off. The power supply is connected to a drive motor. The machine base is also equipped with a start button for starting the drive motor.

[0015] Furthermore, the machine tool is equipped with a parameter setting area for setting the preset torque value and preset running time of the drive motor.

[0016] Furthermore, the machine is also equipped with an emergency stop button to cut off the power and / or shut down the drive motor.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model proposes an automatic locking device, comprising a drive motor, a locking block, and a fixing block arranged sequentially from bottom to top. The output end of the drive motor is equipped with the locking block, which can be connected to the component to be locked. The fixing block has a fixing groove for placing and restricting the rotation of the product, and the product can move axially along the fixing groove. The drive motor drives the locking block to tighten the component to be locked. It is evident that this utility model differs from existing technologies in that it adopts an inverted layout, with the drive motor positioned below and the locking block and fixing block arranged sequentially upwards. This eliminates the limitation of the stacked height of the product and the component to be locked by the entire locking mechanism. This inverted structure effectively solves the problem of high installation space requirements for existing upright locking devices, thereby improving the adaptability of the device in space-constrained environments.

[0020] 2. This utility model proposes an automatic locking device. The fixing block has a fixing groove for placing and restricting the rotation of the product, and the product can move axially along the fixing groove. This prevents the product from rotating during the locking process, avoiding the product and the part to be locked rotating together, ensuring accurate transmission of locking torque, and improving locking precision and reliability. Simultaneously, the product can move freely axially within the fixing groove during the locking process, effectively adapting to the locking needs of products of different specifications and lengths.

[0021] 3. The automatic locking device proposed in this utility model, when the sensor detects that the product is installed in place, the controller controls the drive motor to start, and the locking block begins to lock the product, ensuring that the entire locking process is completed automatically and efficiently.

[0022] 4. The automatic locking device proposed in this utility model uses a servo motor with adjustable torque as the drive motor. The controller shuts down the drive motor based on whether the torque of the servo motor reaches the preset torque value, so that the torque after locking the product is uniform and effectively avoids the phenomenon of loosening by human intervention; or, the controller shuts down the drive motor based on whether the start time of the servo motor reaches the preset running time, so as to avoid the servo motor from continuing to move due to misoperation.

[0023] 5. The unit proposed in this utility model is small in size and light in weight, making it easy for operators to change the position of the unit according to the needs of the site. It is convenient to manually change the work area, and only the power socket needs to be found. Attached Figure Description

Detailed Implementation

[0036] Example 1

[0037] The following is combined with Figures 1-6 This utility model will be described in detail.

[0038] An automatic locking device includes a base 10, a drive motor 20 fixedly mounted on the base 10, a locking block 30 at the output end of the drive motor 20, a groove 301 adapted to the shape of the component 100 to be locked, the groove 301 being able to connect to the component 100 to be locked, and a fixing block 40 on the base 10, the fixing block 40 having a fixing groove 401 for placing and restricting the rotation of a product 90, and the product 90 being movable along the axial direction of the fixing groove 401; wherein, the drive motor 20, the locking block 30 and the fixing block 40 are arranged sequentially from bottom to top in the vertical direction, and the drive motor 20 drives the locking block 30 to tighten the component 100 to be locked.

[0039] As can be seen, the automatic locking device proposed in this embodiment differs from the prior art in that it adopts an inverted layout, with the drive motor 20 positioned below and the locking block 30 and fixing block 40 arranged sequentially upwards. This eliminates the limitation of the stacked height of the product 90 and the component 100 to be locked by the entire locking mechanism. This inverted structure effectively solves the problem of the high installation space requirements of existing upright locking devices, thereby improving the adaptability of the device in space-constrained environments.

[0040] The automatic locking device also includes a control component, which includes a controller and a sensor 50 electrically connected to the controller. The controller is connected to the drive motor 20. The sensing end of the sensor 50 is located in the fixing slot 401 and is used to monitor whether the product 90 is installed in place. Specifically, the controller can be a programmable logic controller, a microcontroller, a microprocessor, or other controller with built-in control programs. The sensor 50 is a through-beam fiber optic sensor 50. The controller starts the drive motor 20 based on the monitoring signal from the sensor 50 to tighten the component 100 to be locked.

[0041] The through-beam fiber optic sensor 50 includes a transmitter 501 and a receiver 502, which are respectively disposed on both sides of the fixing slot 401. When the product 90 is not installed in place, the light signal emitted by the transmitter 501 can be received by the receiver 502. When the product 90 is installed in place, the product 90 blocks the light signal, and the receiver 502 cannot receive the light signal, thus feeding back a signal to the controller. The controller controls the drive motor 20 to start according to the signal change, and then drives the locking block 30 to automatically lock the component 100 to be locked, realizing the automation and intelligence of the locking process, and improving the locking efficiency and reliability.

[0042] The drive motor 20 is a servo motor with adjustable torque. The controller shuts down the drive motor 20 and stops the locking action of the locking block 30 based on whether the torque of the servo motor reaches a preset torque value. This closed-loop control between the servo motor and the controller prevents over-tightening from damaging the product 90. In other embodiments, the controller shuts down the drive motor 20 based on whether the start time of the servo motor reaches a preset running time, preventing accidental start-up of the servo motor when the product 90 is poorly assembled or when there is no product, which could damage the motor.

[0043] like Figure 1As shown, the base 10 includes a support plate assembly and an upright plate 103 connected to one side of the support plate assembly. A drive motor 20 is fixedly connected to the support plate assembly. The support plate assembly has a clearance hole 1011 for the output end of the drive motor 20 to pass through. A fixing block 40 is provided at the end of the upright plate 103 away from the support plate assembly. A locking block 30 is provided in the space between the fixing block 40 and the support plate assembly. The support plate assembly includes a transverse support plate 101 and longitudinal support plates 102 provided on both sides of the transverse support plate 101. The transverse support plate 101 and the longitudinal support plate 102 together form a stable load-bearing structure. The drive motor 20 is fixedly connected to the transverse support plate 101, and the transverse support plate 101 has a clearance hole 1011. Furthermore, the horizontal support plate 101 is provided with a number of opposing positioning grooves 1012, and the two sides of one end of the vertical plate 103 are provided with positioning blocks 1031. The positioning blocks 1031 correspond one-to-one with the positioning grooves 1012 and are engaged to achieve a stable connection between the vertical plate 103 and the horizontal support plate 101.

[0044] The automatic locking device proposed in this embodiment is used as follows:

[0045] S1, such as Figure 2 As shown, in the initial state, the locking component 100 and the product 90 are in a separate state and need to be pre-connected.

[0046] S2, such as Figure 3 As shown, the part to be locked 100 is pre-installed on the product 90, ensuring that it does not fall off when facing downwards;

[0047] S3, such as Figure 4 As shown, when product 90 is placed into the fixing groove 401 of fixing block 40, under the action of gravity, the locking component 100 automatically connects into the groove 301 of locking block 30. At this time, the light signal emitted by the transmitting end 501 of through-beam fiber optic sensor 50 is blocked by product 90, as... Figure 5 As shown, when the receiver 502 cannot receive the light signal, the sensor 50 feeds back the occlusion signal to the controller. After the controller recognizes the signal change, it starts the servo motor. The servo motor drives the locking block 30 to rotate and performs a locking operation on the component 100 to be locked.

[0048] S4, such as Figure 6 As shown, the drive motor 20 automatically shuts off once the preset torque value or running time is reached, completing the automatic locking action. The operator removes product 90, inserts a new product 90, and repeats the above steps.

The machine base 60 is also equipped with a controller, and the switch 701 and the start button 702 are electrically connected to the controller.

[0052] The machine tool 60 is equipped with a parameter setting area for setting the preset torque value and preset running time of the drive motor 20. Furthermore, the machine tool 60 is equipped with a touch screen 703 for displaying the operating status and parameter information of the drive motor 20, and also supports operator input of relevant parameters, such as motor torque value and running time. The touch screen 703 is electrically connected to the controller to achieve precise control of the drive motor 20.

[0053] The machine tool 60 is also equipped with an emergency stop button 704, which is electrically connected to the controller. This button is used to cut off the power supply and / or shut down the drive motor 20 in case of an emergency, ensuring the safety of the equipment and operators. Furthermore, the machine tool 60 is also equipped with an alarm device 705, which is electrically connected to the controller. When the equipment malfunctions, the alarm device 705 is triggered to sound an alarm, alerting the operator to take timely action. Additionally, the alarm device 705 includes an audible and visual alarm, which can be activated immediately when the equipment malfunctions or is not properly locked, improving the safety and reliability of the equipment.
