Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to a turret. Background Technology

[0002] In order to facilitate the machining of different workpieces or different positions of workpieces, CNC machine tools need to be equipped with a tool turret. The tool turret is equipped with several different types of tools. When in use, the required tool is switched to the working position by rotating the turret, and the tool is controlled to machine the workpiece.

[0003] The turret is equipped with a drive mechanism to connect the turret disc, enabling the turret disc to rotate and lock relative to the base. Traditional drive mechanisms are complex and inconvenient to install. Disassembly and assembly are particularly difficult when maintenance or repair of the drive mechanism is required.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0005] The main objective of this invention is to provide a turret that improves the mounting structure of the drive mechanism on the turret, thereby reducing the difficulty of disassembly and assembly.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A turret includes a base, a turret disc, and a drive mechanism for connecting the base and the turret disc. The drive mechanism includes a rotary bearing, a drive gear ring, a pressure gear disc, an inner gear disc, and an outer gear disc. The base has a mounting cavity facing the turret disc for mounting the drive mechanism. The rotary bearing has an inner ring and an outer ring. The inner ring is fixedly connected to the base, and both sides of the outer ring are fixedly connected to the inner gear disc and the drive gear ring, respectively. The turret disc is locked onto the drive gear ring and rotates as the drive gear ring rotates.

[0008] The outer ring gear disk is fixedly mounted on the base and located on the outer periphery of the inner ring gear disk. The pressure plate is located on the inner side of the mounting cavity and can move in the direction of approaching or moving away from the inner ring gear disk and the outer ring gear disk. When the pressure plate abuts against the inner ring gear disk and the outer ring gear disk, the pressure plate simultaneously meshes with the inner ring gear disk and the outer ring gear disk.

[0009] Furthermore, the inner and outer gear disks are respectively provided with a first pressing tooth and a second pressing tooth at the end facing the pressing tooth disk, and a third pressing tooth is formed on the pressing tooth disk; when the pressing tooth disk meshes with the inner and outer gear disks, the third pressing tooth meshes with the first and second pressing teeth simultaneously.

[0010] Furthermore, a spring is provided inside the pressure plate to push the pressure plate against the inner and outer ring gear plates, and a cylinder is also provided on the base. The piston rod of the cylinder is connected to the pressure plate to drive the pressure plate to move axially.

[0011] Furthermore, a drive motor is also provided on the base, and a pinion is connected to the drive motor. An opening is formed on the inner sidewall of the mounting cavity, and part of the pinion passes through the opening and meshes with the outer periphery of the drive gear ring.

[0012] Furthermore, the inner ring gear is threadedly connected to the outer ring by a plurality of first screws; the drive gear is threadedly connected to the outer ring by a plurality of second screws; the outer ring has a plurality of threaded through holes corresponding to the positions of the first screws and the second screws; each threaded through hole is connected to the first screw and the second screw at both ends respectively.

[0013] Furthermore, the turret disc is locked to the drive gear ring, and a gasket is provided between the turret disc and the drive gear ring.

[0014] With the above structure, the turret of this utility model has at least the following beneficial effects:

[0015] 1. Because the drive mechanism is installed in a mounting cavity formed on the base facing the turret plate, the drive mechanism can be easily disassembled and repaired after the turret plate is removed. This reduces the difficulty of disassembling and assembling the drive mechanism compared to traditional turrets.

[0016] 2. The inner gear disc is fixed relative to the outer gear disc by pressing against the inner and outer gear discs. After the pressure disc disengages, the inner gear disc can rotate freely relative to the outer gear disc, thereby enabling the tool on the turret to be changed to the working position.

[0017] Third, the third pressure tooth on the pressure plate meshes with the first and second pressure teeth simultaneously, which is more conducive to ensuring the accuracy of the turret plate.

[0018] Fourth, by connecting the first screw and the second screw together in the threaded through hole on the outer ring, the number of threaded holes on the outer ring is reduced, simplifying the processing difficulty and reducing the production cost.

[0019] Compared with the prior art, this utility model makes the installation and disassembly of the drive mechanism more convenient by installing the drive mechanism inside the turret in the mounting cavity facing the turret plate on the base. Attached Figure Description

Detailed Implementation

[0028] To further explain the technical solution of this utility model, the present invention will be described in detail below through specific embodiments.

[0029] like Figures 1 to 6 As shown, this utility model relates to a turret, which includes a base 1, a turret plate 2, and a drive mechanism 3 for connecting the base 1 and the turret plate 2. The drive mechanism 3 includes a rotary bearing 4, a drive gear ring 5, a pressure gear plate 63, an inner gear plate 61, and an outer gear plate 62. The base 1 has a mounting cavity 11 facing the turret plate 2 for mounting the drive mechanism 3. The rotary bearing 4 has an inner ring 41 and an outer ring 42. The inner ring 41 is fixedly connected to the base 1, and the outer ring 42 is fixedly connected to the inner gear plate 61 and the drive gear ring 5 on both sides, respectively. The turret plate 2 is locked on the drive gear ring 5 and rotates with the rotation of the drive gear ring 5.

[0030] The outer ring gear disk 62 is fixedly mounted on the base 1 and located on the outer periphery of the inner ring gear disk 61. The pressure disk 63 is located on the inner side of the mounting cavity 11 and can move along the direction of approaching or moving away from the inner ring gear disk 61 and the outer ring gear disk 62. When the pressure disk 63 abuts against the inner ring gear disk 61 and the outer ring gear disk 62, the pressure disk 63 simultaneously meshes with the inner ring gear disk 61 and the outer ring gear disk 62.

[0031] In this way, since the drive mechanism 3 is installed in the mounting cavity 11 formed on the base 1 facing the turret plate 2, the drive mechanism 3 can be easily disassembled and repaired after the turret plate 2 is removed. Compared with traditional turrets, this reduces the difficulty of disassembling and assembling the drive mechanism 3.

[0032] The pressure plate 63 abuts against the inner gear plate 61 and the outer gear plate 62, thus fixing the inner gear plate 61 relative to the outer gear plate 62. After the pressure plate 63 disengages, the inner gear plate 61 can rotate freely relative to the outer gear plate 62, thereby enabling the tool on the turret to be changed to the working position.

[0033] Preferably, the inner ring gear disk 61 and the outer ring gear disk 62 are respectively provided with a first pressing tooth 611 and a second pressing tooth 621 at the end facing the pressing tooth disk 63 (e.g., Figure 6 As shown), a third pressing tooth 631 is formed on the pressing tooth disk 63 (as shown). Figure 3 (As shown); when the pressure plate 63 meshes with the inner ring gear plate 61 and the outer ring gear plate 62, the third pressure tooth 631 simultaneously meshes with the first pressure tooth 611 and the second pressure tooth 621. By simultaneously meshing with the first pressure tooth 611 and the second pressure tooth 621, the third pressure tooth 631 on the pressure plate 63 can better ensure the accuracy of the turret plate 2.

[0034] Preferably, the inner side of the pressure plate 63 is provided with a spring 72 that pushes the pressure plate 63 against the inner ring gear plate 61 and the outer ring gear plate 62. The base 1 is also provided with a cylinder 71, the piston rod of which is connected to the pressure plate 63 to drive its axial movement. Furthermore, multiple cylinders 71 are arranged at an annular interval corresponding to the pressure plate 63. Driving the pressure plate 63 with multiple cylinders 71 makes the force on the pressure plate 63 more stable and its movement smoother.

[0035] Preferably, such as Figure 3 As shown, a drive motor 73 is also provided on the base 1, and a pinion 731 is connected to the drive motor 73. A window 732 is formed on the inner sidewall of the mounting cavity 11, and part of the pinion 731 passes through the window 732 and meshes with the outer circumference of the drive gear ring 5. The motor drives the pinion 731, which in turn drives the large-diameter drive gear ring 5, thereby increasing the torque and making the movement of the turret disk 2 more precise.

[0036] Preferably, the inner ring gear 61 is threadedly connected to the outer ring 42 by a plurality of first screws 81; the drive gear 5 is threadedly connected to the outer ring 42 by a plurality of second screws 82; the outer ring 42 has a plurality of threaded through holes 83 corresponding to the positions of the first screws 81 and the second screws 82; each threaded through hole 83 is connected at both ends to the first screw 81 and the second screw 82, respectively. By having the first screws 81 and the second screws 82 at corresponding positions jointly connected to the same threaded through hole 83 on the outer ring 42, the number of threaded holes on the outer ring 42 is reduced, simplifying the processing difficulty and reducing production costs.

[0037] Preferably, the turret disc 2 is locked to the drive gear ring 5, and a gasket 9 is provided between the turret disc 2 and the drive gear ring 5. Furthermore, the outer gear disc 62 is also locked to the base 1 by screws, and a gasket 9 is provided between the outer gear disc 62 and the base 1.

[0038] Compared with the prior art, the present invention makes it more convenient to install and disassemble the drive mechanism 3 by installing the drive mechanism 3 inside the turret in the mounting cavity 11 facing the turret plate 2 on the base 1.

[0039] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
