Description

Technical Field

[0001] This utility model belongs to the field of ball screw slide technology, specifically relating to a precision ball screw slide based on PLC control. Background Technology

[0002] Existing ball screw slides are used to drive the movement of machine frames or objects, transporting them back and forth. However, existing ball screw slides are prone to guide rod bending and unstable load during transport. Furthermore, their integral design leads to long disassembly times and low replacement efficiency, and because they are not enclosed, dust and impurities can fall into the slide during use, shortening its lifespan. Therefore, there is a need to design a ball screw slide with optimized structure, high precision, and high reliability to solve the problems existing in the prior art. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, this utility model provides a precision ball screw slide based on PLC control to solve the problems in the background technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A precision ball screw slide table based on PLC control includes a base, a mounting block on the base, a servo motor on the mounting block, an electromagnetic clutch connected to the output end of the servo motor, and one end of the electromagnetic clutch connected to the lead screw; a slide table is provided on the lead screw, guide rods are slidably connected to both sides of the slide table, one end of the guide rod is connected to a first end plate, and the other end of the guide rod is fixed to a second end plate, and a dust cover is provided on the end plate; a guide groove is provided at the lower end of the slide table, and a guide rail is slidably fitted in the guide groove.

[0006] Furthermore, the base is provided with a guide rail groove, and a fixing hole is provided on the side of the guide rail groove near the edge. A guide rail is slidably connected in the guide rail groove, and the guide rail is fixedly connected to the base.

[0007] Furthermore, a groove is provided at the lower end of the first end plate, and the groove slides in conjunction with the guide rail. The first end plate is fixed to the base by bolts.

[0008] Furthermore, the second end plate is provided with stepped positioning holes, in which guide rods are installed, and the second end plate is fixed to the base by bolts.

[0009] Furthermore, one end of the lead screw is rotatably connected to the first end plate, and the other end is connected to the electromagnetic clutch. The lead screw is rotatably mounted on the second end plate via bearings.

[0010] Furthermore, the slide is provided with a groove, through which the dust cover passes when the slide moves.

[0011] Furthermore, the mounting block is fixed to the base with bolts, and anti-collision blocks are fitted on both ends of the guide rod. The anti-collision blocks are made of rubber material.

[0012] Furthermore, the servo motor and electromagnetic clutch are electrically connected to the PLC controller.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The optimized structural design, such as the sliding fit between the slide table and the guide rail, and the guide rods that slide on both sides of the slide table, enhances the overall stability of the slide table structure, enabling the slide table to remain stable during operation, reducing shaking and vibration, and improving operational reliability.

[0015] The design of the dust cover and the groove of the slide table ensures that the dustproof effect is maintained at all times during the movement of the slide table, preventing dust and other impurities from entering the interior of the slide table, protecting key components and extending the service life of the equipment; the anti-collision blocks at both ends of the guide rod can play a buffering role when the slide table reaches the limit position, avoiding collisions between the slide table and end plates and other components, reducing the risk of equipment damage and ensuring production safety.

[0016] The output shaft of the servo motor is connected to the lead screw via an electromagnetic clutch. The PLC controller outputs a control signal, energizes the electromagnetic coil of the electromagnetic clutch, generates axial attraction, and completes clutch engagement. The PLC controller outputs a power-off signal, and the clutch disengages. At this point, the motor or other components can be replaced. All components are connected by bolts or other means, resulting in a simple structure that is easy to install, disassemble, and maintain, reducing the maintenance cost and difficulty of the equipment.

[0026] like Figure 1-3 As shown, this utility model discloses a precision ball screw slide table based on PLC control, including a base 1, a mounting block 2 on the base 1, a servo motor 3 on the mounting block 2, an electromagnetic clutch 4 connected to the output end of the servo motor 3, and one end of the electromagnetic clutch 4 connected to the lead screw 11; a slide table 6 is provided on the lead screw 11, and guide rods 10 are slidably connected to both sides of the slide table 6, one end of the guide rod 10 is connected to a first end plate 8, and the other end of the guide rod 10 is fixed to a second end plate 9, and a dust cover 5 is provided on the end plate; a guide groove is provided at the lower end of the slide table 6, and a guide rail 7 is slidably fitted in the guide groove.

[0027] Specifically, the sliding engagement between the slide table and the guide rail, with guide rods slidably connected on both sides of the slide table, enhances the overall structural stability of the slide table and improves operational reliability; the output shaft of the servo motor is connected to the lead screw through an electromagnetic clutch, the PLC controller outputs control signals, the electromagnetic coil of the electromagnetic clutch is energized, generating axial attraction force to complete clutch engagement.

[0028] The base 1 is provided with a guide rail groove 13, and a fixing hole 12 is provided on the side of the guide rail groove 13 near the edge. A guide rail 7 is slidably connected in the guide rail groove 13, and the guide rail 7 is fixedly connected to the base 1.

[0029] Specifically, the guide rail is fixed on the base. If the guide rail is damaged, loosen the bolts, pull out the old guide rail along the direction of the guide rail groove, align the new guide rail with the guide rail groove and insert it, and then fix the guide rail with bolts.

[0030] The lower end of the first end plate 8 has a groove, which slides in conjunction with the guide rail 7. The first end plate 8 is fixed to the base 1 by bolts.

[0031] The second end plate 9 is provided with a stepped positioning hole 14, and a guide rod 10 is installed in the stepped positioning hole 14. The second end plate 9 is fixed to the base 1 by bolts.

[0032] Specifically, the bolt connection method has a simple structure, is easy to install, disassemble and maintain, and reduces the maintenance cost and difficulty of the equipment.

[0033] One end of the lead screw 11 is rotatably connected to the first end plate 8, and the other end of the lead screw 11 is connected to the electromagnetic clutch 4. The lead screw 11 is rotatably mounted on the second end plate 9 through a bearing.

[0034] The slide table 6 has a groove, and the dust cover 5 passes through the groove when the slide table 6 moves; the mounting block 2 is fixed to the base 1 by bolts, and anti-collision blocks are fitted on both ends of the guide rod 10. The anti-collision blocks are made of rubber material; furthermore, the servo motor 3 and the electromagnetic clutch 4 are electrically connected to the PLC controller 15.

[0035] Specifically, the anti-collision blocks at both ends of the guide rod can act as a buffer when the slide reaches its limit position, preventing the slide from colliding with components such as the end plate and reducing the risk of equipment damage.

[0036] Operating Principle: First, place the guide rail into the guide rail groove of the base, and secure it to the base using bolts through the fixing holes, ensuring the guide rail is firmly installed and accurately positioned. Next, attach anti-collision blocks to both ends of the guide rod, install the guide rod in the stepped positioning holes of the second end plate, and secure it with bolts. Then, use bolts to fix the second end plate to the base. Next, rotatably connect one end of the lead screw to the first end plate, and mount the other end to the second end plate via a bearing. Slidably engage the groove at the lower end of the first end plate with the guide rail, and similarly, fix the first end plate to the base using bolts. Then, connect the lead screw to the driven end of the electromagnetic clutch, and connect the driving end of the electromagnetic clutch to the servo motor. Simultaneously, use bolts to fix the mounting block and the servo motor to the base. Finally, install the dust cover on the end plate, allowing it to pass smoothly through the groove of the slide table during movement.

[0037] Operation: When the equipment is running, the PLC controls the servo motor to start, and the servo motor drives the lead screw to rotate via an electromagnetic clutch. As the lead screw rotates, the slide moves linearly along the guide rail and guide rod under its drive. When the slide reaches its limit position, the anti-collision blocks at both ends of the guide rod contact the slide, providing a buffer and preventing collisions between the slide and the end plate. Simultaneously, the PLC controls the servo motor, and parameters can be input via the touchscreen. This allows setting the running accuracy of the ball screw slide to 0.01mm, the working time, and the moving speed. Touchscreen input is convenient, fast, and accurate.

[0038] Maintenance Process: During equipment maintenance, the electromagnetic clutch can be disengaged via PLC control, allowing bolts to be removed without shutting down the machine. This facilitates the inspection, cleaning, and replacement of components such as guide rails, guide rods, lead screws, and sliders. Worn anti-collision blocks can also be directly disassembled and replaced. The operation is simple and convenient, effectively reducing the difficulty and cost of equipment maintenance.
