Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to a device suitable for verifying the rotation diameter of a rotary table. Background Art

[0002] The rotation diameter of the rotary table on existing machine tools is usually only shown on the drawings. Without a verification device, it is impossible to intuitively judge whether the rotation diameter is consistent with the drawing on the machine tool on site. Therefore, it is impossible to judge how much margin there is between the rotary table and the surrounding machine tool components (such as guards and castings). This can easily lead to a small gap between the actual rotary table and the surrounding machine tool components, resulting in the accumulation of chips.

[0003] In addition, the workpiece needs to be clamped on the turntable and move in the machine tool as the turntable rotates. It is also necessary to avoid the workpiece from hitting the machine tool. In the existing technology, the rotation interference problem of the turntable is mostly checked by the actual movement of the turntable. The corresponding tools are installed on different models of turntables, and manual visual observation is still required. This is not accurate, inefficient, and subject to human error and interference. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a device suitable for verifying the rotation diameter of a turntable, so as to automatically verify the rotation diameter of the turntable and improve its adaptability to different turntables.

The fixed plate is vertically disposed on the side of the rotary table near the machine tool component. The movable plate is disposed on one side of the fixed plate and extends upward. A sensor mounting base is disposed on the movable plate, and the sensor is disposed on the sensor mounting base and points upward.

[0006] In a preferred embodiment of the present invention, the bottom of the fixing plate is provided with a mounting plate that fits against the turntable, and the mounting plate is provided with a first screw that connects to the turntable.

[0007] In a preferred embodiment of the present invention, the turntable is provided with a positioning hole located below the mounting plate, and the mounting plate is provided with a positioning pin for inserting into the positioning hole.

[0008] In a preferred embodiment of the present invention, the movable plate is provided with a vertically extending waist hole, a second screw connected to the fixed plate is provided in the waist hole, and the fixed plate is provided with a threaded hole corresponding to the second screw.

[0009] In a preferred embodiment of the present invention, a quick-locking clamp connected to a fixed plate is provided on the movable plate, and a scale line located on one side of the quick-locking clamp is provided on the fixed plate.

[0010] In a preferred embodiment of this utility model, a rubber protective sleeve is provided on the top of the movable plate.

[0011] In a preferred embodiment of this utility model, a controller is also included. The sensor is a ranging sensor. The sensor is connected to the controller to send signals. The controller is connected to the turntable to control its operation.

[0012] The beneficial effects of this utility model are as follows: The device for verifying the rotation diameter of a turntable can be mounted on a turntable.

During the relative motion, the distance between the device and the surrounding machine tool components is automatically obtained by the sensor, thereby realizing the automatic verification of the rotation diameter of the turntable. Moreover, the moving plate can be raised and lowered on the fixed plate to change the position and height of the sensor, simulating workpieces of different heights and improving the adaptability to verifying the rotation diameter of different turntables.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figures 1-4The embodiments of this utility model include:

[0020] like Figure 1 and Figure 2 The device shown is for verifying the rotation diameter of a rotary table. It is used to verify the rotation diameter of a rotary table 12 on a machine tool and to avoid impacting the machine tool components 13 around the rotary table 12. It includes: a fixed plate 1, a movable plate 2, a sensor 5, and a controller. The fixed plate 1 is vertically arranged on the rotary table 12 on the side close to the machine tool components 13. In this embodiment, the bottom of the fixed plate 1 is provided with a mounting plate 14 that fits against the rotary table 12. The mounting plate 14 is provided with a first screw 7 that connects to the rotary table 12 for fixing the mounting plate 14.

[0021] The mounting plate 14 and the fixing plate 1 adopt an integrated bending structure or a separate welding structure, which is sturdy. The turntable 12 is provided with positioning holes located below the mounting plate 14, and the mounting plate 14 is provided with positioning pins 6 that are inserted into the positioning holes to position the mounting plate 14, thereby improving the assembly position accuracy and assembly convenience.

[0022] The movable plate 2 is set on one side of the fixed plate 1 and extends upward. The movable plate 2 is equipped with a quick-locking clamp 3 connected to the fixed plate 1, which facilitates the positioning, locking or releasing of the movable plate 2 on the fixed plate 1. After the quick-locking clamp 3 is released, the height of the movable plate 2 can be manually adjusted to simulate workpieces of different heights and improve the adaptability to the rotation diameter verification of different turntables.

[0023] like Figure 4 As shown, a scale line 8 is vertically arranged on the fixed plate 1, located on one side of the quick-locking clamp 3, to indicate the adjustment of the moving plate 2, making operation simple. In this embodiment, the moving plate 2 is provided with a vertically extending waist hole 10, in which a second screw 9 connected to the fixed plate 1 is provided. The fixed plate 1 is provided with a threaded hole corresponding to the second screw 9. Through the cooperation of the waist hole 10 and the second screw 9, the moving plate 2 is guided to rise and fall, and locked after the moving plate 2 is adjusted to prevent loosening.

[0024] like Figure 1 As shown, a sensor mounting base 11 is provided on the movable plate 2, and the sensor 5 is mounted on the sensor mounting base 11 and points upward. In this embodiment, the sensor 5 is a ranging sensor. The sensor 5 is connected to the controller to transmit signals. The controller is connected to the turntable 12 to control its operation and improve the automation level of the calibration.

[0025] like Figure 2 and Figure 3As shown, sensor 5 rotates with the turntable 12. During the relative motion, sensor 5 automatically obtains the distance between itself and the surrounding machine tool components 13, thus achieving automatic verification of the turntable's rotation diameter. The controller can use the machine tool's existing controller, reducing costs. The controller records distance information to analyze and correct interference problems. When the distance signal received by the controller is too small, it can also stop the turntable's rotation to avoid collisions.

[0026] In addition, a rubber protective sleeve 4 is provided on the top of the moving plate 2. The rubber protective sleeve 4 has good elasticity and small impact force when it collides or rubs with the machine tool component 13, effectively reducing the damage to the machine tool component 13 and the moving plate 2 during the calibration process.

[0027] In summary, the device for verifying the rotation diameter of a turntable as described in this utility model is easy to assemble and adjust, can automatically verify the rotation diameter of a turntable, and improves its adaptability to different types of turntables.

[0028] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
