Description

Technical Field

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

[0002] In the field of triaxial inspection mechanisms, comprehensive workpiece inspection to obtain key data such as surface flatness, levelness, and perpendicularity is a crucial step in ensuring that workpiece quality and performance meet standards. During this process, stable workpiece fixation is paramount. Currently, fixtures are widely used as the primary means of workpiece fixation in the industry. However, this traditional method has revealed numerous drawbacks in practical applications.

[0003] When it is necessary to inspect the position on a workpiece that was originally held by a fixture, the operator has to spend a lot of time and effort carefully removing the fixture. After inspecting that position, the fixture must be reinstalled and its position precisely adjusted to inspect other parts of the workpiece. This process is not only tedious and complicated, but the frequent disassembly and installation of the fixture can easily lead to wear on the fixture, which in turn affects its clamping accuracy and stability on the workpiece.

[0004] Furthermore, when changing the clamping position, the lack of a convenient and efficient adjustment mechanism often requires operators to rely on experience for repeated trials and calibrations, which undoubtedly increases the operational difficulty and time cost, severely restricting the overall efficiency of the inspection work. With the increasing demand for high-precision and high-efficiency inspection in industrial production, developing a new workpiece fixing technology that can overcome the shortcomings of existing clamping methods has become a critical issue that urgently needs to be addressed in the field of triaxial inspection mechanisms.

[0005] The purpose of this invention is to provide a testing device that addresses the problem of low testing efficiency mentioned above, facilitates clamping of workpieces at different positions, improves the efficiency of clamping position adjustment, and enhances testing efficiency and accuracy.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A testing device, comprising:

[0008] The detection end is located above the frame;

[0009] A position adjustment mechanism is provided, wherein the detection end is disposed on the position adjustment mechanism, and the position adjustment mechanism is used to adjust the position of the detection end in three-dimensional space and to move it closer to or further away from the workpiece to be detected.

[0010] A clamping base is used to support the workpiece to be inspected;

[0011] A side positioning unit is disposed on the clamping base and is close to or separate from the side of the workpiece to be inspected, and is assembled to perform abutment or separation of the side of the workpiece to be inspected.

[0012] This utility model also has the following technical features:

[0013] In one embodiment of the present invention, at least two side strips are provided on the clamping base, and the two side strips are vertically distributed in the horizontal plane and protrude from the upper plate surface of the clamping base;

[0014] The side positioning unit includes at least a first side positioning strip and a second side positioning strip. The first side positioning strip and the second side positioning strip are vertically arranged in the horizontal plane and are respectively close to or far from the two side strips.

[0015] In one embodiment of the present invention, the first side positioning strip is mounted on the first slide rod, and a first rodless cylinder is also arranged parallel to the side of the first slide rod, and the piston of the first rodless cylinder is connected to the first side positioning strip.

[0016] The second side positioning strip is installed on the second slide rod, which is arranged perpendicular to the first slide rod. A second rodless cylinder is also arranged parallel to the side of the second slide rod, and the piston of the second rodless cylinder is connected to the second side positioning strip.

[0017] In one embodiment of the present invention, the base is provided with a strip-shaped clearance opening, which is used to allow movement of the second side positioning strip, and the strip-shaped clearance opening is arranged parallel to the second slide rod.

[0018] In one embodiment of the present invention, the position adjustment mechanism includes a cantilever, the detection end is disposed at the cantilever end of the cantilever, and the position of the cantilever in the horizontal plane and the vertical plane is adjustable.

[0019] In one embodiment of this utility model, the cantilever end of the cantilever is provided with a rotating base, and the detection end is mounted on the rotating base.

[0020] In one embodiment of this utility model, one end of the cantilever is slidably mounted on a vertical track, a fixing nut is rotatably mounted on the vertical track, the fixing nut cooperates with a vertical lifting screw, the lower end of the vertical lifting screw is connected to the output shaft of a drive motor, the drive motor is vertically slidably mounted on the vertical track, and the upper end of the vertical lifting screw is rotatably connected to the cantilever.

[0021] In one embodiment of this utility model, the fixing nut is fixed on the slider, the slider is fixed on the piston of the first driving cylinder, and the first driving cylinder is arranged horizontally.

[0023] Compared with existing technologies, the beneficial effects of this utility model are reflected in the following: the position adjustment mechanism can flexibly adjust the position of the detection end in three-dimensional space, so that it can quickly approach or move away from the workpiece to be detected. This feature greatly improves the convenience of detection operation. Operators do not need complicated manual adjustments, and can quickly make the detection end reach the ideal detection position, greatly saving detection preparation time and significantly improving the overall detection efficiency.

[0024] The clamping base can stably support the workpiece to be inspected, providing a stable foundation for subsequent inspection. The side positioning unit can approach or separate from the side of the workpiece to be inspected and perform abutment or separation actions. During the inspection process, if different parts need to be inspected, there is no need to disassemble the complex clamps as in the traditional clamping method. By simply controlling the approach or separation of the side positioning unit, the positioning and inspection of different positions of the workpiece can be easily achieved. The operation is simple and efficient.

[0025] With a stable clamping base and flexible side positioning unit, the workpiece can be positioned stably and accurately throughout the entire inspection process, effectively reducing the inspection error caused by inaccurate positioning and greatly improving the inspection accuracy of multiple data such as workpiece surface flatness, levelness, and perpendicularity.

[0026] For workpieces of different shapes and sizes, the effective positioning and inspection of various workpieces can be achieved by adjusting the contact position and force between the side positioning unit and the workpiece, which greatly enhances the applicability of the inspection equipment and meets diverse industrial inspection needs.

[0038] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0039] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0040] It should be noted that, currently, when it is necessary to inspect the position of a workpiece that was originally held by a fixture, the operator has to spend a lot of time and effort carefully removing the fixture. After completing the inspection of that position, the fixture must be reinstalled and its position precisely adjusted to inspect other parts of the workpiece. This process is not only tedious and complex, but the frequent disassembly and installation of the fixture can easily lead to wear on the fixture, thus affecting its clamping accuracy and stability. In addition, when changing the clamping position, due to the lack of a convenient and efficient adjustment mechanism, operators often need to rely on experience to repeatedly try and calibrate, which undoubtedly increases the difficulty and time cost of operation, and seriously restricts the efficiency of the overall inspection work. With the increasing demand for high-precision and high-efficiency inspection in industrial production, developing a new workpiece fixing technology that can overcome the defects of existing fixture fixing methods has become a key problem that urgently needs to be solved in the field of three-axis inspection mechanisms. In this regard, this utility model proposes an inspection device, including: a detection end 10, which is set above the frame 11; a position adjustment mechanism, on which the detection end 10 is set, and the position adjustment mechanism is used to adjust the position of the detection end 10 in three-dimensional space and to move it closer to or further away from the workpiece to be inspected; a clamping base 20, which is used to support the workpiece to be inspected; and a side positioning unit, which is set on the clamping base 20 and is close to or separate from the side of the workpiece to be inspected, and is assembled to abut or separate the side of the workpiece to be inspected.

[0041] In one embodiment, see Figure 1 The position adjustment mechanism enables the detection end 10 to change positions at multiple angles in three-dimensional space, including the X-axis, Y-axis and Z-axis, so that the detection end 10 can effectively contact the workpiece to be detected and improve the flexibility of the entire equipment.

[0042] In one embodiment, see Figure 6 and Figure 7 The detection end 10 can be a mature testing device on the market, such as a flatness tester, micrometer, hardness tester, etc. Through the position adjustment mechanism, it can effectively implement contact with the workpiece to be tested, thereby obtaining various required test data of the workpiece to be tested.

[0043] In one embodiment, the workpiece to be inspected can be clamped by the side positioning unit, thereby ensuring the reliability of the clamping of the workpiece and preventing the workpiece from shifting. The clamping position of the side positioning unit and the workpiece can be changed according to the inspection requirements, so as to achieve effective positioning and inspection of various types of workpieces, greatly enhancing the applicability of the inspection equipment and meeting diverse industrial inspection needs.

[0044] In one embodiment, for positioning and clamping the workpiece to be inspected, see [reference needed]. Figure 4 and Figure 5The clamping base 20 is provided with at least two side strips 21, which are vertically distributed in the horizontal plane and protrude from the upper plate surface of the clamping base 20.

[0045] The side positioning unit includes at least a first side positioning strip 31 and a second side positioning strip 32. The first side positioning strip 31 and the second side positioning strip 32 are vertically arranged in the horizontal plane and are respectively close to or far from the two side strips 21.

[0046] In one embodiment, the shapes of conventional workpieces to be inspected are varied. The workpiece is placed on the clamping base 20. The first side positioning strip 31 and the second side positioning strip 32 of the aforementioned side positioning unit are arranged in parallel to the two side strips 21 respectively. When the first side positioning strip 31 and the second side positioning strip 32 are close to their respective side strips 21, refer to... Figure 4 and Figure 5 This allows the edge of the workpiece to be clamped to abut against the first side positioning strip 31, the second side positioning strip 32, and the side strip 21, thereby clamping and positioning the workpiece.

[0047] In one embodiment, the first side positioning strip 31 is mounted on the first slide rod 311, and a first rodless cylinder 312 is also arranged parallel to the side of the first slide rod 311. The piston of the first rodless cylinder 312 is connected to the first side positioning strip 31.

[0048] See Figure 5 The second side positioning strip 32 is mounted on the second slide rod 321. The second slide rod 321 is arranged perpendicularly to the first slide rod 311. A second rodless cylinder 322 is also arranged parallel to the side of the second slide rod 321. The piston of the second rodless cylinder 322 is connected to the second side positioning strip 32.

[0049] In one embodiment, see Figure 1 The first side positioning bar 31 is arranged along the X-axis direction. The first rodless cylinder 312 can be activated first to move the first side positioning bar 31 along the Y-axis direction, so that the workpiece slides toward one of the side bars 21. The second side positioning bar 32 is arranged along the Y-axis direction. The second rodless cylinder 322 can then be activated to move the second side positioning bar 32 along the X-axis direction, so that the workpiece slides toward the other side bar 21 until it is clamped.

[0050] In one embodiment, see Figure 4 In order to avoid the movement of the second side positioning strip 32, the base 20 is provided with a strip-shaped avoidance opening 22. The strip-shaped avoidance opening 22 is used to avoid the movement of the second side positioning strip 32. The strip-shaped avoidance opening 22 is arranged parallel to the second slide rod 321.

[0051] In one embodiment, see Figure 2 To perform clamping and positioning of the upper surface of the workpiece to be inspected, the inspection equipment also includes a top surface positioning unit. The top surface positioning unit is disposed on the clamping base 20 and is close to or separate from the upper plate surface of the workpiece to be inspected. It is assembled to perform abutment or separation of the upper plate surface of the workpiece to be inspected. The top surface positioning unit includes a top positioning plate 41, which is connected to the piston rod of the vertical cylinder 42.

[0052] The top positioning unit can be started simultaneously with the side positioning unit, or they can be started in opposite directions to ensure the clamping reliability of the workpiece. Alternatively, the workpiece can be clamped separately.

[0053] In one embodiment, for the installation of the detection end 10, the position adjustment mechanism includes a cantilever 51, the detection end 10 is disposed at the cantilever end of the cantilever 51, and the position of the cantilever 51 is adjustable in the horizontal plane and the vertical plane.

[0054] In one embodiment, see Figure 6 and Figure 7 The cantilever 51 is provided with a rotating base 52 at its extended end, and the detection end 10 is mounted on the rotating base 52.

[0055] In one embodiment, the rotating base 52 drives the rotation axis of the detection end 10 along the Y-axis direction, that is, the rotation surface is the vertical plane where the X-axis is located.

[0056] In one embodiment, the rotating base 52 drives the rotation axis of the detection end 10 along the X-axis direction, that is, the rotation surface is the vertical plane where the Y-axis is located, which can further improve the flexibility of the detection end 10.

[0057] In one embodiment, to drive the entire cantilever 51 in the vertical direction (Z-axis), one end of the cantilever 51 is slidably mounted on a vertical track 53. A fixing nut 531 is rotatably mounted on the vertical track 53. The fixing nut 531 cooperates with a vertical lifting screw 532. The lower end of the vertical lifting screw 532 is connected to the output shaft of a drive motor 533. The drive motor 533 is vertically slidably mounted on the vertical track 53. The upper end of the vertical lifting screw 532 is rotatably connected to the cantilever 51.

[0058] When the drive motor 533 is started, the fixed nut 531 and the vertical lifting screw 532 can be in ball screw engagement. When the vertical lifting screw 532 rotates, it can drive the vertical lifting screw 532 and the drive motor 533 to rotate at the fixed nut 531, thereby driving the drive motor 533 to slide vertically on the vertical track 53, thereby driving the cantilever 51 to reciprocate in the Z-axis direction.

[0059] In one embodiment, in order to enable the detection end 10 to move within the water surface, the fixing nut 531 is fixed to the slider 54, the slider 54 is fixed to the piston of the first drive cylinder 55, and the first drive cylinder 55 is arranged horizontally.

[0060] In one embodiment, the first drive cylinder 55 may be a rodless cylinder, and the first drive cylinder 55 is horizontally arranged along the X-axis direction.

[0061] In one embodiment, in order to enable the detection end 10 to move within the water surface, the first drive cylinder 55 is slidably mounted on the horizontal track 56, the horizontal track 56 being arranged perpendicularly to the first drive cylinder 55. The frame 11 is also provided with a second drive cylinder 57, the second drive cylinder 57 being arranged parallel to the horizontal track 56, and the piston of the second drive cylinder 57 being connected to the first drive cylinder 55.

[0062] In one embodiment, the second drive cylinder 57 may be a rodless cylinder. The second drive cylinder 57 is arranged along the Y-axis direction. When the second drive cylinder 57 and the first drive cylinder 55 are activated, the detection end 10 can be adjusted in the horizontal plane.

[0063] In summary, this testing equipment, through its stable clamping base 10 and flexible side and top positioning units, maintains stable and accurate positioning of the workpiece throughout the entire testing process. This effectively reduces testing errors caused by inaccurate positioning and greatly improves the testing accuracy for various data such as workpiece surface flatness, levelness, and perpendicularity. For workpieces of different shapes and sizes, the contact position and force between the side and top positioning units and the workpiece can be adjusted to achieve effective positioning and testing of various workpieces, greatly expanding the applicability of the testing equipment and meeting diverse industrial testing needs.
