Description

Technical Field

[0001] This application relates to the technical field of turrets, and in particular to a power turret. Background Technology

[0002] A power turret is a CNC machine tool that integrates milling, drilling, and tapping functions. It can process complex parts through programming and has a high degree of automated processing capability. The CNC turret mainly consists of a fixed base, a slide, and a tool head. The fixed base has a sliding cavity for the slide to slide. The tool head is rotatably connected to the surface of the slide, and the tool is rotatably connected to the surface of the tool head. The slide is connected to a motor, and the output shaft of the motor is connected to the tool through a spindle. The motor drives the spindle to rotate, thereby driving the tool to rotate to process the workpiece.

[0003] In traditional power turrets, the slide block is driven to slide vertically by a motor screw. The slide block and the fixed seat are rigidly connected, and the contact point between the slide block and the fixed seat is sliding friction, which causes continuous wear at the connection point between the slide block and the fixed seat. After long-term use, the accuracy decreases or even fails. Utility Model Content

[0004] In order to reduce wear between the slide and the fixed seat and improve the service life of the power turret, this application provides a power turret.

[0005] The power turret provided in this application adopts the following technical solution: A power turret includes a fixed base, a sliding base, a rolling assembly, and a lifting drive assembly. The sliding base is slidably connected to the fixed base, and the sliding direction of the sliding base is vertical. The lifting drive assembly is connected to the fixed base and is used to drive the sliding base to slide. The rolling assembly is connected to the sliding base and is slidably connected to the fixed base.

[0006] By adopting the above technical solution, the sliding friction between the slide and the fixed seat is converted into rolling friction by setting the rolling component, thereby reducing the wear caused by the movement of the slide and improving the service life of the power turret.

[0007] Preferably, the slide also includes a cutter head, the slide block includes a base body and a connecting base, the cutter head is rotatably connected to one end of the base body in the horizontal direction, the fixed base is provided with a sliding groove, the sliding groove passes through the fixed base along the rotation axis of the cutter head, the slide block is slidably embedded in the sliding groove, the end of the slide block near the cutter head extends out of the sliding groove, the slide block is connected to two abutment plates on its two sides perpendicular to the rotation axis of the cutter head, the abutment plates are in contact with the side surface of the fixed base near the cutter head, the connecting base is connected to the end of the base body away from the cutter head, the rolling assembly is connected to the side surface of the connecting base near the fixed base, two rolling assemblies are provided, the two rolling assemblies are symmetrically distributed along the rotation axis of the cutter head.

[0008] By adopting the above technical solution, the tool mass of the cutter head and the tool on the outer periphery of the cutter head is relatively large, which makes the slide easier to deflect to the side closer to the cutter head. This reduces the pressure between the abutment plate and the fixed seat, while increasing the pressure between the connecting seat and the fixed seat. The rolling assembly reduces the friction between the connecting seat and the fixed seat, and the abutment plate fits into the fixed seat, increasing the contact area between the slide and the fixed seat, improving the sliding stability of the slide, and improving the reliability of the power turret.

[0009] Preferably, the rolling assembly includes a mounting base and a needle roller. The side surface of the connecting base near the fixed base is provided with a mounting groove. The number of mounting grooves is the same as the number of mounting bases and corresponds one-to-one. The mounting base is embedded in the mounting groove. The needle roller is rotatably connected to the side surface of the mounting base near the fixed base. There are a plurality of needle rollers. The plurality of needle rollers are divided into two groups. The two groups of needle rollers are distributed at intervals along the needle roller rotation axis. The plurality of needle rollers in the same group are distributed at intervals along the sliding direction of the slide block.

[0010] By adopting the above technical solution, the ball bearings are connected to the mounting base, making it easy to remove the mounting base and inspect or replace the ball bearings on the mounting base, thus improving the convenience of installing the rolling assembly.

[0011] Preferably, the rolling assembly further includes two limiting seats, which are symmetrically distributed along the sliding direction of the slide. Each limiting seat has a first connecting hole for a bolt to pass through and be threaded into the connecting seat. One end of the limiting seat near the other limiting seat has a groove. The two ends of the mounting seat along the sliding direction of the slide are respectively embedded in the two grooves. The sidewalls of the mounting seat along the rotation axis of the needle roller are in contact with the groove walls. Positioning blocks are connected to the sidewalls of the mounting seat along the rotation axis of the needle roller. The two ends of the positioning blocks abut against the two limiting seats. An abutting block is connected to the end of the limiting seat near the other limiting seat. The number of abutting blocks is the same as the number of positioning blocks and they correspond one-to-one. The abutting block abuts against the side surface of the positioning block away from the bottom of the mounting groove.

[0012] By adopting the above technical solution, the limiting seat is connected to the connecting seat by bolts and threads. The two ends of the mounting seat are embedded in the grooves of the two limiting seats and fit against the groove walls. The two ends of the positioning block abut against the two limiting seats, and the abutting block abuts against the positioning block, thereby fixing the mounting seat, reducing the possibility of displacement of the mounting seat during the sliding process of the slide, ensuring the rolling connection effect between the needle roller and the fixed seat, and improving the stability and reliability of the power turret operation.

[0013] Preferably, the rolling assembly further includes an elastic sheet and an adjusting bolt. The bottom of the mounting groove is provided with a receiving groove, and the bottom of the receiving groove is provided with an adjusting hole. The elastic sheet is slidably embedded in the receiving groove, and the elastic sheet abuts against the side surface of the mounting base near the receiving groove. The adjusting bolt is threaded into the adjusting hole, and the adjusting bolt abuts against the side surface of the elastic sheet away from the mounting base.

[0014] By adopting the above technical solution, the elastic plate is pushed against the mounting seat by adjusting the bolts. The elastic plate drives the ball to press against the outer wall of the fixed seat, ensuring the rolling connection effect between the needle roller and the fixed seat, and improving the stability and reliability of the power turret operation.

[0015] Preferably, the slide further includes a stop bar, the number of which is the same as the number of rolling components and corresponds one-to-one. The stop bar is connected to the upper end of the connecting column, and the side wall of the stop bar is in contact with the side wall of the fixed seat.

[0016] By adopting the above technical solution, the baffle is used to block external impurities from entering the connection between the slide and the fixed seat, preventing impurities from affecting the rolling of the rolling assembly, maintaining the normal operation of the rolling assembly, reducing wear between the slide and the fixed seat, and improving the service life of the power turret.

[0017] Preferably, the lifting drive assembly includes a lifting drive motor and a lead screw. The lead screw is coaxially rotatably embedded in a slide groove, and the rotation axis of the lead screw is parallel to the sliding direction of the slide block. The lead screw is threadedly connected to the slide block, and the lifting drive motor is connected to a fixed base. The lifting drive motor is used to drive the lead screw to rotate.

[0018] By adopting the above technical solution, the lead screw is driven to rotate by the lifting drive motor. The lead screw is threadedly connected to the slide block, which enables the slide block to slide. This facilitates precise control of the sliding distance of the slide block and improves the stability of the power turret.

[0019] Preferably, the slide further includes a connecting sleeve, the seat body has a communicating hole, the lead screw passes through the communicating hole, the connecting sleeve is connected to the seat body, and the inner wall of the connecting sleeve is threadedly connected to the lead screw.

[0021] Preferably, it also includes mounting bolts. The fixing seat has connecting grooves on the side walls on both sides perpendicular to the rotation axis of the cutter head. The lower wall of the connecting groove has mounting holes. There are a number of mounting holes. The number of mounting bolts corresponds to the number of mounting holes.

[0022] By adopting the above technical solution, several mounting holes are provided on the lower groove wall of the connecting groove on the side wall of the fixed seat, and the mounting bolts are located in the connecting groove, which reduces the possibility of external objects directly mounting the bolt heads and improves the safety of the power turret.

[0023] Preferably, it also includes lifting lugs, which are connected to the upper end of the fixed base. Several lifting lugs are provided, and the several lifting lugs are distributed at intervals along the circumference of the fixed base.

[0024] By adopting the above technical solution, the upper end of the fixed base is equipped with multiple lifting lugs, which facilitates the hoisting and transportation of the power turret.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The rolling assembly converts the sliding friction between the slide and the fixed seat into rolling friction, reducing wear caused by the movement of the slide and improving the service life of the power turret; 2. The large mass of the cutter head and the cutter on its outer periphery makes the slide prone to deflecting towards the side closer to the cutter head. This reduces the pressure between the abutment plate and the fixed seat, while increasing the pressure between the connecting seat and the fixed seat. The rolling assembly reduces the friction between the connecting seat and the fixed seat, and the abutment plate fits closer to the fixed seat, increasing the contact area between the slide and the fixed seat, improving the stability of the slide and the reliability of the power turret. 3. The ball bearings are connected to the mounting base, making it easy to remove the mounting base for inspection or replacement of the ball bearings, thus improving the ease of installation of the rolling assembly.
