Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, and in particular relates to a machine tool precision testing device. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system that can move and process parts according to a pre-programmed program. The parts on CNC machine tools require high-precision fit to ensure that the processed products are qualified. The cutting tools on CNC machine tools can cut the workpiece, so the installation accuracy of the cutting tools has a significant impact on the workpiece.

[0003] Chinese patent publication number (CN205928111U) discloses a CNC machine tool tool installation accuracy testing device. This patented technology moves the tool installation accuracy testing work performed on the machine tool to a dedicated testing device. The piston of the tool-removing cylinder moves upward, pushing the push rod of the tool-removing cylinder upward, pushing the pull rod of the tool-releasing mechanism of the spindle, pushing open the pull claw of the tool-releasing mechanism, and then placing the tool to be tested into the testing part through the taper hole of the spindle. A dial indicator base suction plate is installed on the upper surface of the tool holder plate, and a lever dial indicator is installed on the dial indicator base suction plate. The lever dial indicator needle contacts the part of the tool to be tested. The reduction motor is started, and the speed control switch is adjusted to keep the spindle at a certain speed. The operator visually observes the range of change of the dial indicator value. If the tool accuracy error is within the process requirement range, the tool installation is qualified, which significantly improves the efficiency and success rate of tool installation and testing.

[0004] However, the aforementioned patent cannot detect the flatness of the X and Y axes near the machining platform. Therefore, we propose a machine tool accuracy detection device. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a machine tool precision testing device. By connecting two rotatable support rods to a base with a sliding groove and a magnetically connected perforated base, and connecting a connecting column and a dial indicator to the support rods, the flatness of the X-axis and Y-axis support platforms can be tested.

[0006] This utility model is implemented as follows: a machine tool precision testing device includes a mounting base, an upper part of which is connected to a perforated base, and an upper part of the perforated base is rotatably connected to a first steel ball connector. The first steel ball connector has a first steel ball portion at both its upper and lower parts. An upper part of the first steel ball connector is rotatably connected to a first sleeve, and an upper part of the first sleeve is connected to a first support rod. A first circular plate is welded to the first support rod, and a second circular plate is rotatably connected to the first circular plate. A second support rod is welded to the second circular plate, and a second sleeve is fixedly connected to the second support rod. A second steel ball connector is rotatably connected to the second sleeve, and a connecting post is connected to the lower part of the second steel ball connector. A dial indicator is connected to the lower part of the connecting post. A magnet is embedded in the lower part of the perforated base. A sliding groove is formed in the lower part of the mounting base, and a positioning groove is formed in the upper part of the mounting base. An iron plate is fixedly connected inside the positioning groove.

[0007] Optionally, the second ball connector is provided with a second ball portion at both the upper and lower parts, and the upper end of the connecting post is rotatably connected to the second ball connector through a third sleeve.

[0008] Optionally, an extension rod is fixedly connected to the upper part of the dial indicator, and a cavity for inserting the extension rod is provided inside the connecting column.

[0009] Optionally, a first locking bolt is threadedly connected to the right side of the connecting column, and a first handle is fixedly connected to the first locking bolt.

[0010] Optionally, the dial indicator has a dial on the front side and a probe is connected to the lower part of the dial indicator.

[0011] Optionally, the first circular plate and the second circular plate are connected by a second locking bolt, and a second handle is fixedly connected to the second locking bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By incorporating a sliding groove on the mounting base, this device can be easily adjusted to adapt to worktables of different sizes or shapes. Furthermore, the iron plate fixed inside the positioning groove ensures a more stable fixation to the worktable during use. The magnets embedded in the lower part of the recessed base further strengthen the connection between the device and the worktable, reducing the possibility of positional shifts due to external factors, thereby improving the accuracy of the inspection process.

[0014] 2. An adjustable-angle support structure is constructed using components such as the first steel ball connector, the first sleeve, the first support rod, and the second support rod. The rotational connection between the first steel ball connector and the first sleeve, and the angle adjustability achieved through a circular plate between the first and second support rods, allow the entire support system to be flexibly adjusted according to actual needs. This design allows operators to quickly and accurately adjust the worktable for different height and flatness requirements, greatly facilitating customized use by users according to different scenario needs.

[0015] 3. By combining the connecting column with a dial indicator, highly sensitive detection of minute deviations is achieved: the dial indicator, as a precision measuring tool, is carefully mounted at the bottom of the connecting column, with a detection probe at its front end, capable of sensitively detecting any minute changes on the surface being measured. The extension rod design further expands the effective measuring range of the dial indicator, while the threaded first locking bolt ensures the stability of the extension rod during use.

[0016] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] like Figures 1 to 4As shown in the figure, this utility model provides a machine tool precision testing device.

[0024] The system includes a mounting base 1, with a perforated base 2 magnetically connected to its upper part. A first steel ball connector 3 is rotatably connected to the upper part of the perforated base 2. The first steel ball connector 3 has a first steel ball portion at both its upper and lower parts. A first sleeve 4 is rotatably connected to the upper part of the first steel ball connector 3. The first sleeve 4 has a side notch, allowing it to rotate at a certain angle. The pressure of the first sleeve 4 creates friction, maintaining a certain degree of stability. A first support rod 5 is connected to the upper part of the first sleeve 4. A first circular plate 6 is welded to the first support rod 5. A second... A second circular plate 8 has a second support rod 7 welded on it. A second sleeve 9 is fixedly connected to the second support rod 7. The second sleeve 9 also has a side notch. There is friction between the second sleeve 9 and the second steel ball connector 10. The second steel ball connector 10 is rotatably connected to the second sleeve 9. A connecting post 11 is connected to the lower part of the second steel ball connector 10. A dial indicator 13 is connected to the lower part of the connecting post 11. A magnet block 21 is embedded in the lower part of the perforated base 2. A sliding groove 20 is opened in the lower part of the mounting base 1. A positioning groove 19 is opened in the upper part of the mounting base 1. An iron plate is fixedly connected inside the positioning groove 19.

[0025] The second ball connector 10 has a second ball part at both the upper and lower parts, and the upper end of the connecting post 11 is rotatably connected to the second ball connector 10 through the third sleeve 16.

[0026] The upper part of the dial indicator 13 is fixedly connected to an extension rod 18, and the inside of the connecting column 11 is provided with a cavity for inserting the extension rod 18.

[0027] The right side of the connecting column 11 is connected by a first locking bolt 17 via a thread, and a first handle is fixedly connected to the first locking bolt 17.

[0028] The dial indicator 13 has a dial 12 on the front side and a test probe 14 connected to the lower part of the dial indicator 13.

[0029] The first circular plate 6 and the second circular plate 8 are connected by the second locking bolt 15, and a second handle is fixedly connected to the second locking bolt 15.

[0030] Working principle: First, the mounting base 1 with the slide groove 20 is placed on the machine tool slide to be tested. The position of the entire device can be easily adjusted through the slide groove 20 to adapt to worktables of different sizes or shapes.

[0031] Next, the device is securely attached to the mounting base 1 using the magnet 21 embedded in the lower part of the perforated base 2. This step ensures that the device remains stable throughout the measurement process, reducing movement or offset caused by external factors.

[0032] Once the base 1 is fixed in place, the angles of the first support rod 5 and the second support rod 7 are adjusted. Due to the design of the first ball connector 3 and the second ball connector 10, these two support rods can rotate freely in multiple directions and can be fixed in position by tightening bolts.

[0033] The first circular plate 6 and the second circular plate 8 are connected by a second locking bolt 15, allowing the operator to adjust the relative angle between the support rods as needed, thereby achieving precise control in the X and Y axis directions.

[0034] After adjusting the support structure, the dial indicator 13 is fixed to the appropriate height via the connecting column 11. The extension rod 18 at the top of the dial indicator 13 is inserted into the cavity inside the connecting column 11, increasing the measurement range; while the first locking bolt 17 on the right side of the connecting column 11 is used to lock the position of the extension rod 18 to ensure its stability.

[0035] The probe 14 at the front of the dial indicator 13 lightly touches the surface to be tested, and the flatness test begins. Because the dial indicator 13 has extremely high resolution, it can accurately record any minute surface changes, and these data are directly reflected on the dial 12 of the dial indicator 13.

[0036] Operators can judge whether the flatness of the machine tool table meets the standard requirements based on the displayed data, and make corresponding adjustments accordingly.

[0037] Through the above steps, this machine tool precision testing device can efficiently and accurately test the flatness of the X-axis and Y-axis support platforms. This process not only simplifies the complex operations of traditional testing methods but also improves testing efficiency and accuracy, providing strong support for ensuring product quality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
