Technical Field
[0001] The invention relates to the field of comprehensive fixtures, in particular to a comprehensive fixture for a profilometer. Background Art
[0002] Profilometers are precision instruments widely used to measure workpiece contour dimensions. However, there are currently no dedicated fixtures on the market designed for this purpose, specifically for the comprehensive clamping of shafts or rings. Traditional clamping methods for measuring these products are limited and incompatible, requiring frequent fixture changes depending on the workpiece size, making measurement extremely inconvenient. This is especially true when testing large quantities of parts, which reduces both accuracy and efficiency, significantly complicating inspection tasks.
[0003] Therefore, when measuring parts, how to provide a fixture that can quickly and stably fix shaft or ring parts is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0004] To this end, an embodiment of the present application provides a profile meter comprehensive fixture, which is used in conjunction with the profile meter to measure shaft and ring workpieces, and can ensure the positioning accuracy, stability and reliability of the workpiece during measurement, thereby improving measurement efficiency and measurement accuracy.
[0005] To this end, the following technical solutions are adopted in the embodiments of the present application:
[0006] The profile meter comprehensive fixture includes: a base, on which a guide rail is provided; a first fixture, installed on the guide rail of the base, for pressing and fixing annular workpieces; a second fixture, installed on the guide rail of the base, for pressing and fixing axial workpieces; wherein the first fixture includes a supporting guide plate installed on the guide rail, the supporting guide plate is slidably connected to the guide rail, and a first support for supporting the annular workpiece and a fixed pressure plate for clamping the annular workpiece are installed on the supporting guide plate; the second fixture includes at least two second supports for supporting axial workpieces, a slide is installed on the second support, the second support is slidably connected to the guide rail through the slide, and a mounting seat for installing a fixed pressure plate is provided on the second support, and when the fixed pressure plate is installed on the mounting seat, the fixed pressure plate can press and fix the axial workpiece on the second support.
[0007] In this embodiment, through modular design, the integrated fixture adopts a base and guide rail structure, so that different types of fixtures (first fixture and second fixture) can be flexibly installed and moved on the base. In this way, it can be quickly adjusted according to the size and shape of different workpieces, reducing the need to frequently replace fixtures. Specifically, the first fixture can stably fix the annular workpiece through the combination of a support guide plate and a fixed pressure plate. The sliding design of the support guide plate allows the operator to adjust the position according to the diameter of the workpiece, thereby ensuring good support and clamping. The second fixture has a plurality of support members and a slide design, which can adapt to shaft workpieces of different diameters and lengths. The setting of the slide allows fine-tuning of the workpiece position to ensure precise clamping. For annular and shaft workpieces, the integrated fixture provides uniform clamping force through the fixed pressure plate to prevent the workpiece from moving or deforming during the measurement process, thereby improving the accuracy of the measurement. As a result, the design of the integrated fixture makes the workpiece more stable during the measurement process, reduces the error caused by an inappropriate fixture, and thus improves the accuracy of the measurement. The modular and adjustable design allows for quick adaptation to workpieces of varying sizes during batch testing, reducing setup time and improving efficiency. The integrated fixture can accommodate workpieces of various shapes and sizes, eliminating the need for multiple fixtures for different workpieces and broadening the device's applicability.
[0008] As a feasible implementation, the supporting surfaces of the first supporting member and the second supporting member are arranged in a V shape.
[0009] In this embodiment, the V-shaped support surface can guide the workpiece to automatically align, especially for cylindrical or annular workpieces, helping to ensure the workpiece's stable position in the fixture and reducing measurement errors caused by inaccurate positioning. The V-shaped support surface can accommodate workpieces of different diameters, increasing the versatility of the fixture and reducing the need for different fixtures. The V-shaped support can increase the contact area with the workpiece and improve clamping stability, especially during high-precision measurements, and can effectively prevent the workpiece from moving during the measurement process. The V-shaped structural design facilitates rapid adjustment and clamping of the fixture, improving work efficiency.
[0010] As a feasible embodiment, a plurality of linear guide holes are provided on the support guide plate, the first support member is slidingly connected to one of the linear guide holes, and a first locking knob is installed on one side of the first support member. The first locking knob increases the friction between the first support member and the support guide plate by turning, thereby fixing the first support member on the linear guide hole.
[0011] In this embodiment, the multiple linear guide holes on the support guide plate allow the first support member to slide within a certain range to accommodate workpieces of different diameters and lengths. The operator can quickly adjust the position of the support member according to the specific size of the workpiece. After adjusting the position of the support member, the first support member can be firmly fixed by the locking knob to prevent movement due to external force or vibration during the measurement process, so as to ensure the accuracy of the measurement results. The design of multiple linear guide holes and sliding connections allows the fixture to quickly adapt to different types of workpieces, improving the versatility of the equipment. Locking can be completed through a simple screwing operation, which reduces the complex installation procedure and improves the convenience of operation. It is suitable for rapid switching between different workpieces, and also makes the clamping and adjustment of the workpiece more efficient, greatly shortening the setup time, and is suitable for batch testing. By effectively fixing the workpiece, the measurement error caused by unstable position is reduced, thereby improving the overall measurement accuracy.
[0012] As a feasible embodiment, a slide is installed on the side of the support guide plate facing the base, and the slide is slidably connected to the guide rail. A flipping mechanism is provided between the slide and the support guide plate, and the flipping mechanism enables the support guide plate to freely rotate within the range of -90° to +90° relative to the slide; the flipping mechanism includes a mounting plate provided on the slide, and the mounting plate is U-shaped; the support guide plate can be embedded in the opening of the mounting plate, and a rotating shaft is provided at one end of the support guide plate located inside the mounting plate, and the support guide plate is rotatably connected to the mounting plate via the rotating shaft; a locking handle is provided at one end of the rotating shaft, and the locking handle is used to lock the rotating shaft to limit the rotation of the support guide plate relative to the mounting plate.
[0013] In this embodiment, the sliding connection between the slide and the guide rail allows the support guide plate to move in the horizontal plane, increasing the flexibility and adjustment space of the workpiece fixation. The flip mechanism is composed of a U-shaped mounting plate, and the support guide plate can be embedded in its opening. One end of the support guide plate is rotatably connected to the mounting plate via a rotating shaft, allowing the support guide plate to rotate over a wide range. A locking handle is provided at one end of the rotating shaft, and the operator can lock or unlock the rotating shaft by rotating the handle. After locking, the rotation between the support guide plate and the mounting plate is restricted, thereby fixing their angles. The locking and unlocking operations are simple, and the user can easily complete the adjustment of the support guide plate, which is suitable for operators of different levels.
[0014] As a feasible embodiment, a reset pin is provided on one side of the mounting plate. The reset pin passes through the side wall of the mounting plate and can be embedded in one side wall of the support guide plate to assist in fixing the support guide plate.
[0015] In this embodiment, the reset latch passes through the side wall of the mounting plate and can be embedded in one side wall of the support guide. It should be noted that the design of the latch usually adopts a spring mechanism, which can automatically reset when needed. When the support guide is adjusted to the desired angle, the operator can push or pull the reset latch to embed it into the side wall of the support guide, thereby fixing the position of the support guide. Releasing the latch can unlock the support guide and allow it to be adjusted. The embedding method of the reset latch enhances the stability of the support guide, prevents displacement during operation or vibration, and ensures the accuracy of the workpiece during processing and measurement.
[0016] As a feasible embodiment, the first fixture also includes a first positioning tip, which is slidably connected to the support guide plate, and the first positioning tip can slide along the length direction of the support guide plate; the rear end of the ruby ball at the end of the first positioning tip is equipped with a spring mechanism, which is used to tightly fit the ruby ball at the end of the first positioning tip to the end face of the ring workpiece.
[0017] In this embodiment, the first positioning tip can slide along the length of the support guide plate, so that it can adapt to ring-shaped workpieces of different sizes. This flexibility makes the fixture more adaptable in a variety of workpiece applications. The design of the ruby ball provides high hardness and wear resistance, which can effectively reduce damage to the end face of the workpiece while ensuring high-precision contact. The spring mechanism ensures that the ruby ball always fits tightly to the end face of the workpiece to achieve a stable positioning effect. In other words, the role of the spring mechanism is to maintain close contact between the first positioning tip and the workpiece, avoid displacement of the workpiece during processing, and thus improve the accuracy and consistency of processing.
[0018] As a feasible embodiment, the fixed pressure plate is V-shaped, and a fixed pressure rod is installed on the fixed pressure plate; the fixed pressure plate is slidingly connected to the support guide plate through the fixed pressure rod, and / or the fixed pressure plate is installed on the mounting seat through the fixed pressure rod; and the fixed pressure rod can also adjust the extrusion force of the fixed pressure plate against the ring-type workpiece or the shaft-type workpiece.
[0019] In this embodiment, the fixed pressure plate is designed in a V-shape, which can effectively clamp annular workpieces and shaft workpieces, provide more stable support and positioning, and avoid displacement of the workpiece during the processing. At the same time, the design of the V-shaped pressure plate enables it to adapt to workpieces of different shapes and sizes, thereby improving the versatility of the fixture. The fixed pressure plate is slidably connected to the support guide plate through a fixed pressure rod, allowing the user to adjust it according to the size of different workpieces, thereby enhancing the flexibility of the fixture. The fixed pressure plate can be mounted on the mounting seat via the fixed pressure rod, making the assembly and disassembly of the components more convenient, and maintenance and replacement are also relatively simple. The design of the fixed pressure rod allows the extrusion force of the fixed pressure plate on the workpiece to be adjusted. By adjusting the tightness of the pressure rod, the user can set the appropriate clamping force according to the material and characteristics of the workpiece to prevent the workpiece from being deformed or damaged. At the same time, through the adjustment of the fixed pressure rod, the pressure plate can apply pressure evenly, enhance the stability of the workpiece, and ensure accuracy and consistency during the processing process. This design allows users to quickly adapt to the needs of different workpieces, reduces setup time, and improves work efficiency.
[0020] As a feasible implementation, the second support member is provided with at least one weight-reducing hole, and a hard alloy column is provided on the support surface of the second support member.
[0021] In this embodiment, at least one weight-reducing hole is provided on the second support member. This design aims to reduce the overall weight of the assembly while maintaining the necessary structural strength. The distribution and number of weight-reducing holes can be optimized according to actual needs to improve the performance of the support member. The design of the weight-reducing holes helps reduce the weight of the support member, making it more convenient during installation and operation, and suitable for use in situations where frequent movement or position adjustment is required. Carbide columns are provided on the support surface of the second support member. These columns provide additional wear resistance and strength, and are suitable for working conditions requiring high wear resistance and long-term use, extending the service life of the support member. Moreover, the carbide columns can provide solid support, increase the contact area, effectively disperse pressure, and prevent deformation or damage to the material during use. The second support member effectively improves the performance of the support member through the rational layout of weight-reducing holes and carbide columns, ensuring the necessary strength while reducing weight. It is suitable for a variety of working conditions and meets the needs of modern manufacturing and processing for efficient and durable support components.
[0022] As a feasible embodiment, the second clamp also includes a second positioning tip, and the rear end of the ruby ball of the second positioning tip is equipped with a spring mechanism, which is used to tightly fit the ruby ball at the end of the second positioning tip into the end face of the shaft workpiece; a guide rod is provided on the second positioning tip, and the second positioning tip is slidably connected to the guide rod, and a fixed seat is provided at one end of the guide rod, and the fixed seat is long and has a waist-shaped long hole on the fixed seat, and a second locking knob is installed in the waist-shaped long hole, and the second locking knob is screwed to one side wall of the base, and the second locking knob fixes the fixed seat to one side of the base by screwing.
[0023] In this embodiment, a spring mechanism is installed at the rear end of the ruby ball of the tip, ensuring that the ruby ball fits tightly against the end face of the axial workpiece. The spring mechanism provides the necessary elasticity, allowing the tip to effectively adapt to slight errors when contacting the workpiece, thereby ensuring accurate positioning. The second positioning tip is connected to the fixed base via a guide rod. The sliding design of the guide rod allows the tip to move freely in the longitudinal direction. This design enables the tip to be adjusted according to the actual position of the workpiece, improving the adaptability of the fixture. The combination of the spring mechanism and the sliding connection design enables the second positioning tip to accurately fit the workpiece, significantly improving the positioning accuracy of the fixture and making it suitable for machining applications requiring high precision. The fixed base is elongated and has a waist-shaped slot. This slot design allows the second locking knob to be adjusted within a certain range, facilitating flexible fixing on workpieces of varying sizes. The waist-shaped slot design provides a wider adjustment range, allowing the fixture to adapt to workpieces of varying diameters or lengths, enhancing the fixture's versatility. The second locking knob is screwed onto the side wall of the base, effectively adjusting the position of the fixed base and ensuring the stability of the positioning tip. This design allows operators to quickly and easily adjust and lock the clamp's position. The threaded design of the second locking knob simplifies operation and quickly locks and unlocks the clamp, reducing adjustment time and improving work efficiency. The combination of hard materials (such as ruby balls) and a spring mechanism enhances the overall structural stability and durability, extending the life of the clamp. The design's versatility and adaptability make it suitable for a wide range of shaft workpieces, ensuring strong compatibility during machining and meeting diverse production needs.
[0024] As a feasible embodiment, the interior of the base is hollow, and a positioning locking screw is provided on one side of the base, and the positioning locking screw is used to fix the base on the workbench of the profilometer; the base is also provided with a scale line, and the scale line is located on one side of the guide rail, which is used to provide precise positioning length for the sliding of the first clamp and the second clamp on the guide rail.
[0025] In this embodiment, the base adopts a hollow design, so that the base reduces the overall weight while maintaining strength, is easy to operate and move, and improves the convenience of use. The positioning locking screw is arranged on one side of the base, and can be fixed to the workbench of the profilometer by rotating, locking or loosening. This design ensures the stability of the base during use, prevents position displacement due to vibration or external force, and improves the stability and accuracy of processing. The scale lines are located on the base and are adjacent to the guide rail, providing a visual reference standard. These scale lines provide precise positioning lengths for the sliding of the first clamp and the second clamp on the guide rail, so that the operator can set the sliding length more conveniently and accurately when adjusting the position of the clamp. Through intuitive scale lines and simple locking mechanisms, operators can quickly set and adjust, reducing operation time and improving work efficiency.
[0026] In summary, the profilometer integrated fixture, through its unique design and functionality, effectively addresses the shortcomings of traditional measuring fixtures, providing a more efficient and accurate solution for inspection. Specifically, this fixture provides a positioning and clamping tool for measuring shafts and rings with profilometers. This makes the integrated fixture widely applicable, ensuring accurate, stable, and reliable workpiece positioning when profilometers are measuring, thereby improving measurement efficiency and accuracy. The integrated fixture is lightweight, simple to mount, and highly adaptable. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 A schematic diagram of the three-dimensional structure of the profilometer integrated fixture provided in an embodiment of the present application is shown. Figure 2 Shown Figure 1 Another perspective of the integrated fixture. Figure 1 and Figure 2 As shown, the integrated fixture includes a base 1 and a first fixture 2 and a second fixture 3 installed on the base 1 .
[0039] One side of the base 1 is equipped with a positioning locking screw 4 for mounting the base 1 on the profilometer workbench (not shown). Specifically, the positioning locking screw 4 can be rotated to lock or loosen after positioning to secure the base 1 in the measurement position on the profilometer workbench. On the side of the base 1 facing away from the profilometer workbench, several guide rails 11 are provided for the sliding movement of the first and second clamps 2 and 3. The first clamp 2 is mounted on the guide rails 11 of the base 1 and is used to clamp and secure annular workpieces; the second clamp 3 is mounted on the guide rails 11 of the base 1 and is used to clamp and secure axial workpieces.
[0040] After adjusting the positions of the first and second fixtures 2 and 3 on the guide rails 11, the center of the workpiece secured thereto is positioned at the center of the profilometer, allowing the profilometer to inspect the workpiece. Thus, the modular design of this integrated fixture, utilizing the base 1 and guide rails 11, allows different types of fixtures (the first and second fixtures 2 and 3) to be flexibly installed and moved on the base 1. This allows for quick adjustments based on the size and shape of different workpieces, reducing the need for frequent fixture changes.
[0041] Figure 3 Shown Figure 1 Another perspective view of the integrated fixture. Figure 3 At the same time, review Figure 1 and Figure 2 The base 1 serves as the base of the entire fixture, and all components use it as a platform for installation and movement. The side of the base 1 facing away from the guide rail 11 is a hollow structure with an opening. Hollow holes 12 are provided on opposite sides of the base 1 to reduce the overall weight of the base 1. This lightweight design makes the integrated fixture more flexible during use, helping to improve work efficiency, especially in environments where frequent equipment movement is required.
[0042] Optionally, in the present embodiment, two guide rails 11 are provided on the base 1, and the guide rails 11 are provided on the side of the base 1 away from its own opening. It should be noted that the number of guide rails 11 can also be three, four, or even more than four, mainly based on the sliding and fixing needs of the first clamp 2 and the second clamp 3. The present application strictly limits the number of guide rails 11. For the sake of clarity, the following description will be specifically described as having two guide rails 11. For example, the two guide rails 11 are parallel to each other and extend along the length direction of the base 1. Scale lines 13 are respectively provided on the side of the two guide rails 11 away from each other, and the scale lines 13 are provided on the base 1, which provide precise positioning lengths for the sliding of the first clamp 2 and the second clamp 3 on the guide rails 11, so that the operator can more conveniently and accurately set the sliding length when adjusting the position of the clamps.
[0043] Continue reading Figure 1 and Figure 2 , the first fixture 2 includes a support guide plate 21 and a first support member 22 mounted on the support guide plate 21. The support guide plate 21 is a long rectangular plate, and a fixed pressure plate 5 is mounted on the support guide plate 21. The fixed pressure plate 5 is used to cooperate with the first support member 22 to fix the annular workpiece on the support guide plate 21. Optionally, the number of fixed pressure plates 5 can be one, two, three or more. The specific number of fixed pressure plates 5 can be specifically set according to the workpiece to be fixed, and this application does not impose strict restrictions on this. For example, in this embodiment, the number of fixed pressure plates 5 is set to two.
[0044] In one embodiment, both the fixed pressure plate 5 and the first support member 22 can adjust their positions on the support guide plate 21 according to the size of the annular workpiece to be measured. Specifically, in order to facilitate the fixation and sliding of the fixed pressure plate 5 and the first support member 22, a plurality of linear guide holes 211 are provided on the support guide plate 21. The linear guide holes 211 are waist-shaped long holes 381, and the extension direction of the linear guide holes 211 is the length direction of the support guide plate 21. It should be noted that in this embodiment, three linear guide holes 211 are provided, and the three linear guide holes 211 are arranged in parallel. The linear guide hole 211 in the middle is used to install the first support member 22, and the other two linear guide holes 211 correspond to the installation of the above-mentioned two fixed pressure plates 5 respectively. In this way, the two fixed pressure plates 5 and the first support member 22 can adjust their positions on the support guide plate 21 according to the annular workpiece to be measured while reducing the possibility of mutual interference.
[0045] It should be noted that the first support member 22 rests against the support guide plate 21, with the side of the first support member 22 facing the fixed platen 5 serving as its supporting surface. To better support the annular workpiece, the supporting surface of the first support member 22 is V-shaped. This allows the annular workpiece to be positioned relative to its outer circumferential surface. Once placed on the first support member 22, the workpiece's curved protrusion is better supported by the first support member 22. The workpiece can then be compressed by the two fixed platens 5, allowing measurement of the annular workpiece.
[0046] To facilitate adjustment of the position of the first support member 22 on the support guide plate 21, a first locking knob 23 is provided on the other side of the first support member 22 facing the linear guide hole 211. The first locking knob 23 is located on the other side of the support guide plate 21, facing away from the first support member 22. The first locking knob 23 can be threaded onto the sidewall of the first support member 22 through the linear guide hole 211. In some embodiments, the sidewall of the first support member 22 facing the linear guide hole 211 can partially extend into the linear guide hole 211, facilitating both installation of the first locking knob 23 and sliding movement of the first support member 22 within the linear guide hole 211. After moving the first support member 22 to the desired position, the operator can tighten the first locking knob 23 to increase the friction between the first support member 22 / first locking knob 23 and the support guide plate 21 until the first support member 22 is unable to move on the support guide plate 21, thereby securing the first support member 22 to the support guide plate 21.
[0047] In some embodiments, the fixed pressure plate 5 is V-shaped, and a fixed pressure rod 51 is installed on the fixed pressure plate 5, which passes through the side wall of the fixed pressure plate 5, and the fixed pressure plate 5 can slide along the length direction of the fixed pressure rod 51. The fixed pressure plate 5 is slidably connected to the support guide plate 21 through the fixed pressure rod 51. Specifically, a sliding block 24 is respectively installed in the two linear guide holes 211 on both sides of the support guide plate 21, and the sliding block 24 is a waist-shaped design. The fixed pressure rod 51 (the thread of the fixed pressure rod 51 is not shown in the figure) is threadedly connected to the sliding block 24, and the fixed pressure rod 51 can pass through the sliding block 24. In this way, the fixed pressure rod 51 abuts the fixed pressure plate 5 on the annular workpiece by controlling the depth of itself being screwed into the sliding block 24, and the extrusion force of the fixed pressure plate 5 against the annular workpiece can also be adjusted. It is worth noting that the sliding block 24 is slidably connected to the linear guide hole 211. However, the preload force between the sliding block 24 and the linear guide hole 211 is sufficient to support the fixed pressure plate 5 after it is installed on the sliding block 24 without sliding relative to the linear guide hole 211. When the position of the fixed pressure plate 5 needs to be adjusted, the operator only needs to push the sliding block 24 along the length of the linear guide hole 211 using the fixed pressure rod 51.
[0048] In some embodiments, the first fixture 2 further includes a first positioning tip 25, which is slidably connected to the support guide plate 21 and can slide along the length of the support guide plate 21. Specifically, to mate with the first support member 22, the first positioning tip 25 is mounted in a linear guide hole 211 in the center of the support guide plate 21. For example, a sliding block 26 is slidably connected within the linear guide hole 211, and the first positioning tip 25 extends through the sliding block 26. The sliding block 26 can slide along the length of the linear guide hole 211, thereby sliding the first positioning tip 25 to a desired position. Optionally, a positioning knob 27 is mounted on the sliding block 26. Tightening the positioning knob 27 increases the frictional resistance between the sliding block 26 and the linear guide hole 211, thereby securing the sliding block 26 in the linear guide hole 211. Thus, the positioning knob 27 prevents the sliding block 26 from sliding in the linear guide hole 211, thereby fixing the position of the first positioning tip 25.
[0049] Exemplarily, the positioning knob 27 can be used to fix the sliding block 26 in the following manner: for example, two sliding posts (not shown) located on the same straight line and arranged opposite each other are installed inside the sliding block 26, and the end of the positioning knob 27 can be inserted into the gap between the two sliding posts. The end of the positioning knob 27 is configured to be arc-shaped. By controlling the depth of the positioning knob 27 screwed into the gap between the two sliding posts, the top ends of the two sliding posts facing away from each other abut against the side walls of the linear guide hole 211, thereby limiting the sliding of the sliding block 26 on the linear guide hole 211. This application does not provide a detailed description of the specific structure of the sliding block 26 and the positioning knob 27.
[0050] In one embodiment, the first positioning tip 25 includes a ruby ball disposed at an end and a spring mechanism disposed at a rear end. The spring mechanism is used to tightly fit the ruby ball at the end of the first positioning tip 25 against the end surface of the ring-shaped workpiece. It is understood that the structure of the spring mechanism in the first positioning tip 25 that supports the ruby ball is a mature technology and is not described in detail in this application.
[0051] Continue reading Figure 1 and Figure 2A slide 28 is mounted on the side of the support guide plate 21 facing the base 1, and the slide 28 can slide on the guide rail 11. In one embodiment, in order to fix the slide 28, a snap-on knob 281 is mounted on the slide 28. The snap-on knob 281 can be screwed to increase the friction between the slide 28 and the guide rail 11, thereby fixing the slide 28 on the guide rail 11. In another embodiment, a plurality of fixing holes 14 arranged in parallel can be opened on the guide rail 11 (only one is shown in the figure). After the slide 28 is slid to the desired position, the snap-on knob 281 is aligned with the fixing hole 14 at that position, and the snap-on knob 281 is screwed into the fixing hole 14, the slide 28 and the guide rail 11 can be fixed. In some embodiments, a step block (not shown) may be installed on the guide rail 11. The step block is a long, toothed structure, i.e., the step block is rack-shaped, with a pitch between teeth equal to one step. The clamping knob 281, acting as one end of a plunger, can be positioned in the toothed structure of the step block, cooperating with the scale lines 13 to achieve positioning of the workpiece to be measured. Similarly, the clamping knob 281 can also be consistent with the structure of the positioning knob 27 fixing the slide block 26 described above. As long as the slide 28 can be fixed to the guide rail 11, the specific limiting structure of the clamping knob 281 is not limited in this application.
[0052] Optionally, a flip mechanism 29 is provided between the slide 28 and the support guide plate 21, and the flip mechanism 29 enables the support guide plate 21 to freely rotate within a range of -90° to +90° relative to the slide 28. In one embodiment, Figure 4 The structural diagram of the flip mechanism 29 is shown as follows: Figure 4As shown, the tilting mechanism 29 includes a mounting plate 291 mounted on the slide 28. The mounting plate 291 is U-shaped, with the side of the mounting plate 291 facing away from the opening being fixedly connected to the slide 28. For a stable connection, the mounting point of the mounting plate 291 to the slide 28 is located in the middle of the bottom side of the mounting plate 291. The support guide 21 can be inserted into the opening of the mounting plate 291. A rotating shaft 292 is fixedly connected to one end of the support guide 21 located within the mounting plate 291. The support guide 21 is rotatably connected to the mounting plate 291 via the rotating shaft 292. Correspondingly, latches 293 are provided on opposite sides of the opening of the mounting plate 291 to accommodate the sliding installation of the rotating shaft 292. To secure the support guide 21 after it has been tilted to the desired position, a locking handle 294 is provided at one end of the rotating shaft 292. It will be understood that the locking handle 294 is used to lock the rotating shaft 292, thereby limiting the rotation of the support guide 21 relative to the mounting plate 291. Specifically, the locking handle 294 can be screwed onto the end of the rotating shaft 292. The depth of the locking handle 294 screwed into the rotating shaft 292 can then be controlled to control the friction between the locking handle 294 and the sidewall of the mounting plate 291, thereby securing the rotating shaft 292 to the mounting plate and locking the support guide plate 21 at a desired angle. This ensures that during measurement and operation, the support guide plate 21 can be rotated as needed to maintain a secure position, preventing the workpiece from moving due to unexpected vibration or external forces.
[0053] Optionally, when the support guide plate 21 is in a vertical position (i.e., the initial state), in order to assist in fixing the support guide plate 21, a reset pin 295 is provided on one side of the mounting plate 291. One end of the reset pin 295 passes through the side wall of the mounting plate 291 and can be embedded in the slot 212 on the side wall of the support guide plate 21, cooperating with the rotating shaft 292 to limit the support guide plate 21 to the initial position. At this time, the locking handle 294 can lock the support guide plate 21 without locking the rotating shaft 292. In this way, when measuring annular workpieces, the unlocking process of the locking handle 294 can be omitted. After adjusting the angle of the support guide plate 21, the locking operation of the locking handle 294 is performed, thereby further improving the detection efficiency. It should be noted that the resetting of the reset pin 295 can be achieved by a spring reset structure. The above-mentioned spring reset structure is a mature related technology and will not be described in detail in this application.
[0054] In this way, thanks to the design of the flipping mechanism 29, the support guide plate 21 can rotate freely between -90° and +90° relative to the mounting plate 291, which is convenient for adjusting the angle. After the profile meter reaches the optimal measuring position, it is locked and fixed by the locking handle 294 to fix the rotation angle. This design provides greater operational flexibility and is easy to adapt to the needs of different workpieces.
[0055] See Figure 1 and Figure 2, the second fixture 3 includes at least two second support members 31 for supporting shaft-type workpieces. It can be understood that shaft-type workpieces are positioned by the shaft diameter. In order to better fix the shaft-type workpieces, two second support members 31 are provided. The two second support members 31 are arranged in parallel, and the support surface of the second support member 31 facing away from the base 1 is V-shaped, so as to better place and support the shaft-type workpiece. At the same time, the second support member 31 is provided with at least one weight-reducing hole 311. It can be understood that the number of weight-reducing holes 311 needs to ensure the strength of the second support member 31 on the basis of reducing the weight of the second support member 31. In this embodiment, two weight-reducing holes 311 are provided. In order to increase the durability of the second support member 31, a carbide column 312 is provided on the support surface of the second support member 31, and the carbide column 312 completely covers the V-shaped support surface of the second support member 31.
[0056] Optionally, a mounting base 32 for mounting the fixed pressure plate 5 is fixedly connected to the second support member 31. The mounting base 32 is located on one side of the second support member 31 and has a reserved insertion hole 321 for screwing the fixed pressure rod 51 therein. The fixed pressure rod 51 is threadedly connected to the reserved insertion hole 321. When the fixed pressure rod 51 mounts the fixed pressure plate 5 on the mounting base 32, the fixed pressure plate 5 can follow the movement of the fixed pressure rod 51 to press the shaft workpiece against the second support member 31.
[0057] Optionally, a slide 33 is mounted on the second support member 31, and the second support member 31 is slidably connected to the guide rail 11 via the slide 33. Similarly, a limit screw 34 is mounted on the slide 33 for limiting the slide 33 on the guide rail 11 so that it cannot slide. The limit screw 34 fixes the slide 33 on the guide rail 11 by screwing. The structure of the limit screw 34 limiting the slide 33 is the same as the structure of the above-mentioned clamping knob 281 limiting the slide 28, and will not be repeated here. The two second support members 31 are mounted on the slide 33 on the base 1 and slide freely along the guide rail 11, so that the distance between the two second support members 31 can be adjusted according to the length of the workpiece. When precise positioning is required, the corresponding distance can be moved according to the scale line 13 on the base 1.
[0058] In one embodiment, the second fixture 3 further includes a second positioning tip 35. A spring mechanism is installed at the rear end of the ruby ball of the second positioning tip 35. The spring mechanism is used to tightly fit the ruby ball at the end of the second positioning tip 35 against the end surface of the shaft-like workpiece. It will be appreciated that the structure of the spring mechanism holding the ruby ball in the second positioning tip 35 is a mature technology and is not described in detail in this application.
[0059] Optionally, a guide rod 36 is provided on the second positioning tip 35. The second positioning tip 35 is slidably connected to the guide rod 36 via a tightening block 37. The second positioning tip 35 can also be fixed to any position on the guide rod 36 by the tightening block. The structure of the tightening block 37 is a mature technology and is not described in detail here. The guide rod 36 is arranged vertically, and a fixing seat 38 is fixed to the end of the guide rod 36 facing the base 1. The fixing seat 38 is an elongated strip and has a waist-shaped long hole 381 formed on the fixing seat 38. A second locking knob 39 is installed in the waist-shaped long hole 381. The second locking knob 39 is screwed to a side wall of the base 1. The second locking knob 39 is screwed to fix the fixing seat 38 to one side of the base 1. Correspondingly, a guide slot 15 is provided on one side of the base 1 to accommodate the sliding movement of the fixing seat 38. The guide slot 15 extends along the length of the base 1, and a plurality of threaded holes 16 are provided at the bottom of the guide slot 15 for accommodating the second locking knob 39 for threaded attachment. These threaded holes 16 are arranged along the length of the guide slot 15 to facilitate adjustment of the position of the second locating tip 35 according to the size of the axial workpiece to be measured. In this way, when it is necessary to measure the relative position of the workpiece end face to other measured surfaces, the second locating tip 35 of the axial end face can be moved up and down along the guide rod 36 to adjust the vertical position of the second locating tip 35; while the fixing seat 38 can move horizontally along the guide slot 15 of the base 1, conveniently adjusting the horizontal position of the locating tip according to the length of the workpiece, thereby facilitating the measurement of axial workpieces.
[0060] In summary, the shaft and ring parts comprehensive fixture in this embodiment is a special comprehensive fixture designed for the profilometer. It is used in conjunction with the profilometer to measure shaft and ring workpieces, ensuring the positioning accuracy, stability and reliability of the workpiece during measurement, and improving measurement efficiency and measurement accuracy.
