Description

Technical Field

[0001] This utility model relates to the field of positioner maintenance technology, specifically to a tooling that facilitates the disassembly and assembly of the positioner drive device. Background Technology

[0002] A positioner is an automated device used to adjust the spatial posture of a workpiece. Through precise motion control, it can stably fix the workpiece in the optimal operating position, reducing the intensity of manual adjustment. It is widely used in welding, machinery manufacturing, aerospace, automotive and other fields.

[0003] The key component of a positioner is the drive unit, which includes a motor, a gearbox, etc., and is installed inside the positioner's housing. In the existing technology, when repairing the positioner's drive unit, the housing of the positioner must be opened first, and then the drive unit must be disassembled for repair or replacement. However, because the motor and gearbox of the drive unit are heavy, it is difficult to support them manually when disassembling them. If manual support is used, the motor may shake due to fatigue or other factors, posing a safety risk and reducing maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tooling that facilitates the disassembly and assembly of the positioner drive device, which is convenient for maintenance and can improve the efficiency and safety of the maintenance process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tooling for easy assembly and disassembly of a positioner drive unit includes two sliding rods and a limiting part connected to the housing of the positioner. The sliding rods are used to support the front end of the drive unit, and the limiting part is used to support the rear end of the drive unit. The drive unit is slidably connected to the sliding rods, and the extension direction of the sliding rods is parallel to the motor axis in the drive unit.

[0006] Optionally, a mounting plate is installed on the front side inside the housing. The mounting plate is used to install the drive device, and the slide rod is connected to the mounting plate.

[0007] Optionally, the mounting plate of the drive device is provided with a sliding groove, which slides in conjunction with the slide rod.

[0008] Optionally, a support plate is provided on the rear side inside the housing, the support plate being used to support the slide rod.

[0009] Optionally, the driving device moves outward along the slide bar and then attaches to the limiting part.

[0010] Optionally, the limiting part includes a connecting rod, one end of which is detachably connected to the housing, and the other end of which is provided with a first support plate for supporting the motor.

[0011] Optionally, the support plate is provided with a stop portion, which contacts the side of the mounting plate opposite to the fixing plate.

[0012] Optionally, the limiting part is slidably connected to the slide rod, and the limiting part and the driving device move outward along the slide rod synchronously.

[0013] Optionally, the limiting part includes a fixing plate and a sliding plate. The support plate is connected to the housing through the fixing plate. The end of the sliding rod away from the fixing plate extends to the outside of the housing. One end of the sliding plate is slidably connected to the sliding rod located on the outside of the housing. The other end of the sliding plate is used to support the motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) In this utility model, by installing two sliding rods and a limiting part inside the positioner, the front and rear ends of the drive device are supported. When repairing the drive device, the drive device can be slid out of the positioner along the sliding rods, which is convenient for repair. When the drive device is installed after repair, the position of the drive device can be controlled more precisely, which is convenient for installation and improves the efficiency of the repair process. (2) In this utility model, by setting a support plate at one end of the slide rod to support the slide rod, it is possible to avoid the large weight of the drive device from damaging the slide rod when the drive device slides along the slide rod to the outside of the positioner, thereby improving the stability and safety of the device; (3) In this utility model, by setting a stop part that contacts the drive device on the support plate, the drive device can be limited when the drive device is pulled out of the positioner, so as to avoid the drive device being pulled out of the positioner directly, thereby improving the stability and safety of the positioner.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0017] Example 1, as Figure 1 , Figure 2 As shown, a tooling for easy assembly and disassembly of a positioner drive unit is provided. The positioner 1 includes a drive unit 101 and a housing 102. A fixing plate 103 and a support plate 3 are provided on the housing 102. The fixing plate 103 is installed on the front side inside the housing 102. The front side inside the housing 102 is the side of the housing 102 that faces the output end of the drive unit 101. The drive unit 101 is mounted on the fixing plate 103. The gearbox of the drive unit 101 is connected to a mounting plate 105. The drive unit 101 also includes a motor 104. The mounting plate 105 has multiple holes, which can be used to connect the mounting plate 105 and the fixing plate 103 through the holes using detachable fasteners such as screws or bolts. Due to the variable... Positioner 1 has only one opening, making it inconvenient to repair drive device 101. When repairing drive device 101, fasteners need to be removed first, and mounting plate 105 and fixing plate 103 need to be separated. Then drive device 101 needs to be removed from positioner 1 and moved to the opening of positioner 1 for repair. However, due to the excessive weight of components such as motor 104 and gearbox in drive device 101, manual handling may cause damage to drive device 101 due to lack of physical strength. In addition, after the repair is completed, when drive device 101 is reinstalled on positioner 1, the original positional accuracy cannot be guaranteed.

[0018] like Figure 3 , Figure 5As shown, in order to safely move the drive unit 101 to the maintenance position and ensure positioning accuracy during maintenance of the drive unit 101, two sliding rods 2 are installed on the housing 102 of the positioner 1 to support the front end of the drive unit 101. The sliding rods 2 are located on both sides of the drive unit 101 and are slidably connected to the drive unit 101. That is, the sliding rods 2 are slidably engaged with the sliding grooves 106 provided on the mounting plate 105. The drive unit 101 slides along the sliding rods 2 through the sliding grooves 106, and the extending direction of the sliding rods 2 is parallel to the axis of the motor 104 of the drive unit 101. The system ensures that the drive device 101 can slide back to the installation position along the slide bar 2 after maintenance, facilitating subsequent installation and improving maintenance efficiency. The positioner 1 is equipped with a limiting part to support the rear end of the drive device 101. When the drive device is being maintained, both the front and rear ends are supported to ensure stability and facilitate maintenance. When the drive device 101 is being maintained, it is pulled to the maintenance position along the slide bar 2. After maintenance, the drive device 101 returns to the installation position along the slide bar 2, ensuring positional accuracy and improving maintenance efficiency.

[0019] Furthermore, a support plate 3 is provided on the rear side inside the housing 102. The rear side inside the housing 102 is the side opposite to the output end of the drive device 101. The support plate 3 is detachably fixed to the housing 102. When the drive device 101 is being repaired, the support plate 3 is installed to support the two slide rods 2, which facilitates the repair of the drive device 101. After the repair of the drive device 101 is completed, the support plate 3 is removed, and then the next positioner 1 is repaired.

[0020] Specifically, the slide rod 2 is fixedly connected to the fixed plate 103. The fixed connection between the slide rod 2 and the fixed plate 103 is detachable, preferably a threaded connection. This allows the slide rod 2 to be removed when the drive device 101 is not being maintained, and then installed back onto the fixed plate 103 when maintenance is required. This improves the utilization rate of the slide rod 2, and the same slide rod 2 can be used for positioners of the same model, thereby reducing production costs.

[0021] Specifically, there are two ways to support both the front and rear ends of the drive device. First, when the drive device 101 needs to be repaired, the drive device 101 moves outward along the slide bar 2 and then attaches to the limiting part. Second, the limiting part is set on the slide bar 2 and is slidably connected to the slide bar 2. When the drive device 101 needs to be repaired, the limiting part and the drive device 101 move outward along the slide bar 2 synchronously.

[0022] Example 2: This example provides a tooling for easy disassembly and assembly of the positioner drive device. This example is an optimization based on Example 1 to refine the technical solution. For details not described in this example, please refer to Example 1. This example specifically introduces the first method of supporting both the front and rear ends of the drive device.

[0023] like Figure 4 As shown, specifically, after the drive unit 101 is disassembled, it moves outward along the slide bar 2 towards the outer casing 102 and attaches to the limiting part. Specifically, the limiting part includes a connecting rod 4 and a first support plate 5. One end of the connecting rod 4 is detachably connected to the outer casing 102, allowing the connecting rod 4 to be removed when the drive unit 101 is not being maintained, and then reinstalled on the outer casing 102 when maintenance is required. This improves the utilization rate of the connecting rod 4, and the same connecting rod 4 can be used for the same model of positioner, thereby reducing production costs. The other end of the connecting rod 4... A first support plate 5 is provided to support the motor 104. The connecting rod 4 is connected to the positioner 1 by fasteners and is installed on the housing 102 by detachable fasteners such as screws. The first support plate 5 is fixedly connected to the connecting rod 4. The first support plate 5 is shaped to correspond to the outer contour of the motor 104 and can support the motor 104. This application provides a limiting part to support the rear end of the drive device 101 and supports the motor 104 by the first support plate 5, thereby improving the stability of the device and ensuring safety when maintaining the drive device 101.

[0024] Specifically, when the drive unit 101 is moved outside the positioner 1 by the operator and the motor 104 is located outside the positioner 1, the connecting rod 4 is installed on the housing 102 and the motor 104 is supported by the first support plate 5, which facilitates the maintenance of the drive unit 101.

[0025] like Figure 5 As shown, the drive device 101 moves along the slide bar 2 to the support plate 3 via the slide groove 106. The stop part 301 provided on the support plate 3 contacts the side of the mounting plate 105 opposite to the fixed plate 103, limiting the drive device 101. This can prevent the drive device 101 from falling due to incorrect distance estimation when it is pushed out, thus ensuring safety and stability of the device.

[0026] like Figure 2 As shown, a second support plate 6 for supporting the motor 104 is further provided between the two slide rods 2, and the two slide rods 2 are slidably connected to the sliding frame 7, and the second support plate 6 is threadedly connected to the sliding frame 7. The height of the second support plate 6 can be adjusted according to the motor 104 in different types of positioners 1 to support the motor 104.

[0027] Specifically, when the drive device 101 is moved outward, the second support plate 6 supports the motor 104, and the sliding frame 7 also moves outward along the slide rod 2. After the first support plate 5 contacts the motor 104, the second support plate 6 and the sliding frame 7 are removed from the slide rod 2 for maintenance of the drive device 101. This improves the stability of the movement when the drive device 101 moves outward.

[0028] Example 3: This example provides a tooling for easy disassembly and assembly of the positioner drive device. This example is an optimization based on Example 1 to refine the technical solution. For details not described in this example, please refer to Example 1. This example specifically introduces a second method for supporting both the front and rear ends of the drive device.

[0029] like Figure 6 As shown, the limiting part is provided on the slide rod 2 and is slidably connected to the slide rod 2. When the drive device 101 needs to be repaired, the drive device 101 is disassembled, and the limiting part supports the drive device 101 to move outward along the slide rod 2. Specifically, the limiting part includes a fixing plate 8 and a sliding plate 9. The support plate 3 is connected to the outer shell 102 through the fixing plate 8. The end of the slide rod 2 away from the fixing plate 103 extends outward from the outer shell 102. One end of the sliding plate 9 is slidably connected to the slide rod 2 located outside the outer shell 102, and the other end of the sliding plate 9 is used to support the motor 104. The drive device 101 can be stably moved to the outside of the outer shell 102 for repair.

[0030] Working principle: When repairing the drive device 101, remove the detachable fasteners connecting the mounting plate 105 and the fixing plate 103, slide the drive device 101 outward along the two slide rods 2, and when it reaches the repair position, the limiting part supports the motor 104. Repair and replace the parts. After the repair is completed, the drive device 101 moves inward along the two slide rods 2 to the installation position, and installs the drive device 101 on the positioner 1.
