Description

Technical Field

[0001] The present invention belongs to the field of measurement technology, and in particular relates to a three-coordinate universal combined tooling. Background Art

[0002] Coaxiality detection is one of the key points of dimensional measurement. Especially in the design of motor base, the accuracy of coaxiality directly affects the performance of the motor. For example, when the motor coaxiality is unqualified, it is easy to cause quality problems such as motor failure, electromagnetic noise, motor scratches, etc.

[0003] As a professional measuring tool for coaxiality detection, the three-dimensional coordinate measuring machine is often used in the coaxiality measurement of motor bases because it can measure the coaxiality of different parts with high accuracy while ensuring the efficiency of detection. There are many different models and sizes of motor bases currently produced. Typical base types include: B3 base with feet, B5 base without feet, long and short types under each model, and different series such as T series and E series.

[0004] In conventional practice, one tool is usually used for one type of machine base to perform inspection. Therefore, for different types of machine bases, multiple sets of different tools need to be made. In the laboratory, space is limited, so the storage of multiple sets of tools will be a problem. In addition, since there is no component conveying and positioning device on the inspection table, each installation or removal of the tool requires time to align and re-establish the tool coordinate system, affecting the inspection efficiency. In addition, since the three-coordinate measurement uses manual point measurement, it is labor-intensive and the measurement method is not unified, which is prone to large measurement errors and poor measurement repeatability. When measuring machine bases of different models and sizes, if it is necessary to re-align and establish the working coordinate system, the measurement accuracy is further affected.

[0005] Therefore, the inventors realized that a set of suitable tooling may be needed to meet the automatic execution of the measurement program, especially when the models and sizes of the machine bases to be measured are different. Different machine bases can be measured without changing the tooling. On the one hand, this avoids the manufacturing costs, time costs and waste of space resources caused by multiple sets of tooling. On the other hand, it can also avoid re-alignment and establishment of the tooling coordinate system, simplify the measurement procedure and reduce measurement errors. Utility Model Content

[0006] An object of the present disclosure is to provide a three-coordinate universal combined tooling, which can be used for measuring workpieces of different models and sizes.

[0007] Another object of the present disclosure is to provide a three-coordinate universal combined tooling, which can simplify the measurement procedures for different workpieces and reduce measurement errors.

[0008] To achieve any one of the above-mentioned purposes, the present disclosure provides a three-coordinate universal combination tooling, including: a base plate, which is in the shape of a flat plate and extends on a horizontal plane and includes a plurality of tooling mounting holes, and the base plate is detachably fixed to the three-coordinate work platform via the plurality of tooling mounting holes; and an adjustable fixing assembly, which is used to fix the base of a first workpiece on the base plate, including: a positioning pin, which is detachably mounted to the positioning hole of the base plate; a first guide rail mechanism, which is arranged in a linear guide rail groove extending in a first direction along the base plate, and includes a first track embedded in the guide rail groove and a first slider capable of sliding in the first direction along the first track; and a moving pin, which is detachably mounted to the pin hole of the first slider so as to move in the first direction as the first slider slides.

[0009] In the present disclosure, by providing the above-mentioned three-coordinate universal combination tooling with adjustable fixing components, workpieces of different models and sizes can be measured without changing the tooling, thereby avoiding the waste of manufacturing costs, time costs and space resources caused by multiple sets of tooling.

[0010] Further, the positioning pin is arranged on the axis along which the first track is located near the starting end of the first track. The positioning pin includes a positioning pin head protruding upward from the upper surface of the substrate, and the positioning pin head is a cylindrical pin head; and the moving pin includes a moving pin head protruding upward from the top surface of the first slider, and preferably, the moving pin head is a diamond pin head; wherein the positioning pin head and the moving pin head are respectively used to cooperate with the first fixing hole and the second fixing hole on the bottom foot of the first workpiece in a detachable manner so as to be fixed to the upper surface of the substrate along the first direction.

[0011] In the present disclosure, the locating pin can be connected and fixed to the workpiece on the one hand, and can position the workpiece relative to the substrate of the tooling on the other hand. This makes it possible for the workpiece to be positioned relative to the substrate with the same coordinate reference when measuring different workpieces, thereby helping to avoid re-alignment and establishment of the tooling coordinate system, simplifying the measurement procedure, and reducing measurement errors.

[0012] In addition, the positioning pin head adopts a cylindrical pin head, while the movable pin head adopts a diamond pin head, which ensures the accurate positioning of the workpiece on the one hand, and reduces the difficulty of assembling and disassembling the workpiece on the other hand.

[0013] Furthermore, the first guide rail mechanism further includes a first scale arranged along the first track, and the first scale indicates the distance of the moving pin relative to the positioning pin in the first direction, so that the moving pin can be quickly positioned according to the axial size of the workpiece, saving debugging time.

[0014] Furthermore, the adjustable fixing assembly also includes a fastening device, which includes: a first fastening screw, which is passed through a first fastening hole on the side of the substrate, the first fastening hole is connected to the positioning hole to allow the first fastening screw to lock the positioning pin in the positioning hole via the first fastening hole, and a second fastening screw, which is passed through a second fastening hole on the side of the substrate, the second fastening hole is elongated along the first direction and connected to the guide rail groove to allow the second fastening screw to lock the first slider at different positions of the first rail via the second fastening hole.

[0015] Further, the first guide rail mechanism includes a third fastening screw, which is arranged in a third fastening hole on the side of the first sliding block, and the third fastening hole is connected to the pin hole to allow the third fastening screw to lock the moving pin in the pin hole via the third fastening hole.

[0016] In the present disclosure, by providing the above-mentioned fastening screws, the requirements for the dimensional accuracy of the shaft-hole matching and the difficulty of assembly are reduced, and the firmness of positioning and installation can be ensured.

[0017] Preferably, the first slider is in rolling contact with the first track; and the top surface of the first slider is flush with the upper surface of the substrate.

[0018] In the present disclosure, the top surface of the first slider is always flush with the upper surface of the substrate to ensure that when different workpieces are fixed on the substrate, the central axis direction is parallel to the first direction and is in the horizontal plane. Since the first guide rail mechanism adopts a roller linear guide rail, compared with an ordinary sliding guide rail, since the relative sliding between planes is converted into the rolling of the roller on the plane, the adjustment of the stroke of the first slider is easier and more labor-saving.

[0019] Furthermore, the substrate may be an integrated flat plate; or optionally, the substrate may be formed by detachably joining a plurality of substrate parts, which allows the substrate to be expanded as needed according to workpieces of different sizes or models to better fit different workpieces.

[0020] Furthermore, the three-coordinate universal combined tooling also includes at least one standard ball mounting hole arranged on the base plate, which allows the stylus to be calibrated without disassembling the tooling.

[0021] Furthermore, the three-coordinate universal combined tooling according to the present disclosure also includes an adjustable support, which is used as a foot to support the second workpiece when the second workpiece to be measured does not have a foot. The adjustable support includes: a base plate, which is flat and extends on a horizontal plane and includes a third fixing hole and a fourth fixing hole arranged along a first direction, and the third fixing hole and the fourth fixing hole are respectively matched with a positioning pin and a movable pin to fix the adjustable support to the upper surface of the base plate in a detachable manner; a pair of parallel second guide rail mechanisms, which are arranged on both sides of the upper surface of the base plate and extend along the first direction, and respectively include a second track and a second slider capable of sliding in the first direction along the second track; a fixed support plate, which is fixed to the upper surface of the base plate along a second direction perpendicular to the first direction; and a movable support plate, which is arranged on a pair of parallel second guide rail mechanisms parallel to the fixed support plate, wherein both ends of the movable support plate in the second direction are respectively supported by the second slider, so that it can move in the first direction as the second slider slides on the second track.

[0022] In the present disclosure, by providing such an adjustable support with a movable support plate, the three-coordinate universal combined tooling according to the present disclosure can be adapted to workpieces of different models and sizes, even if the workpiece does not have a supporting portion such as a foot.

[0023] Furthermore, the fixed support plate and the movable support plate are aligned in the first direction and are located near the starting end of the first guide rail mechanism; and the fixed support surface of the fixed support plate and the movable support surface of the movable support plate are at the same height. This ensures that when the second workpiece is placed on the adjustable support, its central axis direction is parallel to the first direction and is in a horizontal plane.

[0024] Furthermore, a limit member is provided on the side of the fixed support plate opposite to the movable support plate, and the limit member is arranged to be able to move between an extended position exceeding the fixed support surface and a retracted position below the fixed support surface, thereby ensuring that when different workpieces are placed on the adjustable support, the workpieces can be accurately positioned by making the end of the workpiece rest against the limit member.

[0025] Furthermore, the fixed support surface and the movable support surface have the same shape and are both "V"-shaped, and both the fixed support surface and the movable support surface are provided with concave-convex patterns, which not only enhance the wear resistance of the support surface but also improve the aesthetics.

[0026] Further, the second slider is in rolling contact with the second track. Similar to the first guide rail mechanism, the pair of parallel second guide rail mechanisms both use roller linear guide rails, making the adjustment of the stroke of the second slider easier and more labor-saving.

[0027] Furthermore, the adjustable support further comprises a second scale arranged parallel to the second track, and the second scale indicates the distance of the movable support plate relative to the fixed support plate in the first direction.

[0028] In addition, a scale indicator is provided on the second slider, which has a downwardly protruding tip portion, which is close to the second scale and aligned with the central axis of the movable support plate along the first direction to indicate the specific scale of the movable support plate corresponding to the second scale.

[0029] In the present disclosure, by providing the above-mentioned second ruler and scale indicator, the positioning accuracy of the movable support plate is further improved, which is conducive to the rapid and accurate positioning of the movable support plate.

[0030] Furthermore, limit blocks are provided at both ends of the second track to limit the displacement stroke of the second sliding block in the first direction.

[0031] Furthermore, a fourth fastening screw is provided on the second sliding block to lock the second sliding block at different positions of the second track.

[0032] In the present disclosure, the stability of the second guide rail mechanism is improved by providing the above-mentioned limit block and the fourth fastening screw.

[0033] The present disclosure provides the above-mentioned universal three-coordinate clamping tool, which can not only adapt to various types and sizes of workpieces to be measured at the same time, but also enable measurement of different workpieces without changing the tooling, thus avoiding the manufacturing cost, time cost and waste of space resources caused by multiple sets of tooling; it can also realize fast and accurate positioning of the workpiece on the tooling, thereby allowing any type of workpiece to be switched quickly at any time, and avoiding re-alignment and establishment of the tooling coordinate system; furthermore, the tooling can be fixed on the detection table for a long time, firmly clamps the workpiece without blocking the measured part of the workpiece, and prevents interference between the probe and other structures during measurement, thereby reducing the programming difficulty, simplifying the measurement procedure and reducing measurement errors.

[0069] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0070] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form as well.

[0071] Figure 11 is a three-dimensional schematic diagram of a three-coordinate universal combined tooling 100 in a first use state according to an embodiment of the present disclosure. In the first use state, a workpiece 1 (a first workpiece, taking a B3 type machine base as an example) having a foot 10 is directly mounted on the upper surface of the tooling 100 through a first fixing hole 12 and a second fixing hole 14 on the foot 10, and the tooling 100 is horizontally mounted on a working platform T of a three-coordinate measuring machine. At this time, the tooling 100 does not need to use an additional support to support the workpiece 1.

[0072] See below for more information. Figure 2a to Figure 2c The structure of the tooling 100 according to the embodiment of the present disclosure will be described in detail. The three-coordinate universal combination tooling 100 according to the embodiment of the present disclosure includes: a base plate 110, which is in the shape of a flat plate and extends on a horizontal plane and includes a plurality of tooling mounting holes 102, and the base plate can be detachably fixed to the three-coordinate work platform T via the plurality of tooling mounting holes; an adjustable fixing assembly, which is used to fix the base 10 of the workpiece on the base plate. The upper and lower surfaces of the base plate are strictly planes, so that in the assembled state, the lower surface of the base plate can fit tightly on the work platform T, while the upper surface of the base plate provides a horizontal surface for supporting the workpiece. Figure 2a As shown, the plurality of tooling mounting holes 102 are preferably arranged equidistantly in a straight line direction (for example, along the first direction X), and the spacing between the tooling mounting holes 102 corresponds to the spacing between the mounting holes on the work platform T, so that the tooling 100 can be installed at any suitable position on the work platform T according to actual needs.

[0073] Among them, the adjustable fixing component includes: a positioning pin 120, which can be installed in the positioning hole 101 of the substrate in a detachable manner; a first guide rail mechanism, which is arranged in a linear guide rail groove 106 extending along the first direction X of the substrate, and includes a first track 130 embedded in the guide rail groove 106 and a first slider 132 that can slide in the first direction X along the first track 130; and a moving pin 140, which is installed in the pin hole of the first slider 132 in a detachable manner so that it can move in the first direction X as the first slider slides.

[0074] Preferably, the base plate 110 is rectangular, the first direction X is the long side direction of the base plate, and the linear guide groove 106 is adjacent to a long side of the base plate and extends from near one end of the base plate to the end of the other end. The positioning pin 120 is arranged on the axis along which the first track 130 is located near the starting end of the first track 130.

[0075] Figure 3 and Figure 4The three-dimensional schematic diagrams of the positioning pin and the moving pin according to the embodiment of the present disclosure are respectively shown. As shown in the figure, the positioning pin 120 includes a positioning pin head 122 and a positioning pin shaft 124 extending downward from the lower end of the positioning pin head 122, and the positioning pin shaft 124 is used to be installed in the positioning hole 101 of the substrate. In the installed state, the positioning pin head 122 protrudes upward from the upper surface of the substrate, and the positioning pin head 122 is preferably cylindrical, so as to be assembled with the first fixing hole 12 on the foot 10 of the workpiece 1 in a transition fit manner; the moving pin 140 includes a moving pin head 142 and a moving pin shaft 144 extending downward from the lower end of the moving pin head 142, and the moving pin shaft 144 is used to be installed in the pin hole. In the installed state, the moving pin head 142 protrudes upward from the top surface of the first slider 132, and the moving pin head 142 can be cylindrical, and more preferably rhombus-shaped, so as to be matched with the second fixing hole 14 on the foot 10 of the workpiece 1.

[0076] In particular, the locating pin 120 is used to connect and fix with the workpiece 1 on the one hand, and to position the workpiece 1 relative to the substrate of the tooling on the other hand, so that when measuring different workpieces, the workpieces are positioned relative to the substrate with the same coordinate reference; since the movable pin 140 can move in the first direction X to adjust the distance between it and the fixed pin, even if the sizes of different workpieces in the first direction X are different, the other end of the workpiece can be fixed to the tooling via the movable pin when one end of the workpiece is positioned via the locating pin 120.

[0077] Therefore, through the positioning pin 120 and the movable pin 140, a workpiece of any size can be detachably fixed on the upper surface of the substrate 110 along the first direction X. In addition, the positioning pin head 122 is cylindrical, and the movable pin head 142 is preferably rhombus-shaped. On the one hand, the transition fit between the positioning pin head 122 and the first fixing hole 12 ensures accurate positioning of the workpiece. On the other hand, the rhombus-shaped pin head of the movable pin 140 reduces the friction resistance with the inner wall of the first fixing hole 14, thereby reducing the difficulty of assembling and disassembling the workpiece.

[0078] Preferably, the first guide rail mechanism also includes a first scale 136 arranged along the first rail 130, and the first scale 136 indicates the distance of the moving pin 140 relative to the positioning pin 120 in the first direction X, so that the moving pin can be quickly positioned according to the axial size of the workpiece, saving debugging time.

[0079] See also Figure 2a and Figure 2bThe adjustable fixing assembly further includes a fastening device, which includes: a first fastening screw 104, which is inserted into a first fastening hole on the side of the substrate 110, and the fastening hole is connected to the positioning hole 101 to allow the first fastening screw 104 to lock the positioning pin 120 in the positioning hole 101 through the first fastening hole, specifically, as Figure 3 As shown, a fastening groove 126 is provided on the locating pin shaft 124 of the locating pin 120, and the fastening groove 126 is used to cooperate with the first fastening screw 104 to strengthen the locking of the locating pin 120; and a second fastening screw 105, which is passed through a second fastening hole 150 on the side of the substrate 110, and the second fastening hole 150 is elongated along the first direction X and connected to the guide rail groove 106 to allow the second fastening screw 105 to lock the first slider 132 at different positions of the first track 130 via the second fastening hole 150.

[0080] In addition, the first guide rail mechanism further includes a third fastening screw 134, which is disposed in a third fastening hole on the side of the first slider 132, and the third fastening hole is connected to the pin hole to allow the third fastening screw 134 to lock the moving pin 140 in the pin hole via the third fastening hole. Specifically, Figure 4 As shown, a fastening groove 146 is provided on the moving pin shaft 144 of the moving pin 140 , and the fastening groove 146 is used to cooperate with the third fastening screw 134 to strengthen the locking of the moving pin 140 .

[0081] The above-mentioned fastening screws not only reduce the requirements for the dimensional accuracy of the shaft-hole fit and the difficulty of assembly, but also ensure the firmness of positioning and installation.

[0082] Considering that workpieces of different models may have fixing holes of different sizes, it is only necessary to specifically set positioning pins and movable pins with pin heads of different sizes for different workpieces. Through the replaceable design of positioning pins and movable pins, the tooling according to the present disclosure can be more conveniently adapted to workpieces of various sizes and models.

[0083] Preferably, the first slider is in rolling contact with the first track; and the top surface of the first slider is not higher than the upper surface of the substrate, and preferably the two are flush. By making the first guide rail mechanism adopt a roller linear guide rail, compared with an ordinary sliding guide rail, since the relative sliding between planes is converted into the rolling of the roller on the plane, the adjustment of the stroke of the first slider is easier and more labor-saving. In addition, the top surface of the first slider is always flush with the upper surface of the substrate, ensuring that when different workpieces are fixed on the substrate, the central axis direction of the workpiece is always parallel to the first direction and in the horizontal plane.

[0084] According to the tooling 100 of the embodiment of the present disclosure, the base plate 110 may be a one-piece flat plate structure, or alternatively, the base plate 110 may be formed by at least one flat plate being assembled and disassembled, such as Figure 2a and Figure 2c As shown, in this example, the substrate 110 is assembled from a first substrate portion 110A and a second substrate portion 110B, wherein the second substrate portion 110B is equivalent to an extension portion, which can be selected according to the size of the workpiece to be measured, and its size can also be set according to the size of the workpiece to be measured. Figure 2c In this example, the adjacent portions of the first substrate portion 110A and the second substrate portion 110B are in the form of step matching, which is conducive to leveling between the two to ensure that the upper surfaces of the two are at the same level. Here, it can be understood that the components of the substrate are not limited to one or two substrate portions, but can be arbitrarily expanded according to actual needs.

[0085] Preferably, the substrate 110 is made of 45# steel and is nickel-plated on the surface to increase the surface aesthetics and wear resistance of the substrate 110 .

[0086] Next, we will see Figures 5 to 7 A second use state of the tool and a corresponding structure according to an embodiment of the present disclosure are described.

[0087] like Figure 5 As shown, the tool 100 according to the embodiment of the present disclosure may further include an adjustable support 200 mounted on the base plate 110. When the workpiece 2 to be measured (the second workpiece, taking the B5 type motor base as an example) does not have a foot, the adjustable support 200 may serve as a foot to support the workpiece 2. In this example, the same structure will not be repeated, and only the structure not mentioned in the previous example, namely the adjustable support 200, will be specifically described.

[0088] Combination Figure 5 and Figures 6a to 6cThe adjustable support includes: a bottom plate 210, which is flat and extends on a horizontal plane and includes a third fixing hole 212 and a fourth fixing hole 214 arranged along the first direction X, and the third fixing hole 212 and the fourth fixing hole 214 are respectively used to cooperate with the positioning pin 120 and the moving pin 140 to fix the adjustable support 200 to the upper surface of the base plate 110 in a detachable manner; a pair of parallel second guide rail mechanisms, which are arranged on both sides of the upper surface of the bottom plate 210 and extend along the first direction X, and respectively include a second track 240 and a second track 241. And a second slider 242 capable of sliding along the second track 240 in the first direction X; a fixed support plate 220, which is fixed to the upper surface of the base plate 210 along a second direction Y perpendicular to the first direction X; and a movable support plate 230, which is arranged parallel to the fixed support plate 220 on the aforementioned pair of parallel second guide rail mechanisms, wherein the two ends of the movable support plate 230 in the second direction Y are respectively supported by two second sliders 242, so that it can move in the first direction as the second slider 242 slides on the second track 240.

[0089] The first guide rail mechanism is similar, and the pair of parallel second guide rail mechanisms can also use roller linear guide rails. Compared with ordinary sliding guide rails, the roller linear guide rail converts the relative sliding between planes into the rolling of the roller on the plane, making the adjustment of the stroke of the second slider easier and more labor-saving.

[0090] The fixed support plate 220 and the movable support plate 230 are aligned in the first direction X and are located near the starting end of the first guide rail mechanism, and the fixed support surface of the fixed support plate 220 and the movable support surface of the movable support plate 230 are at the same height to ensure that when the workpiece 2 is placed on both, the center axis direction is parallel to the first direction and is in a horizontal plane.

[0091] Optionally, a pair of limit members 222 are provided on the side of the fixed support plate 220 opposite to the movable support plate 230, and the limit members 222 are arranged to be able to move between an extended position exceeding the fixed support surface and a retracted position below the fixed support surface, so that when the workpiece 2 is placed on the fixed support surface, the workpiece 2 can be precisely positioned by making the end of the workpiece 2 rest against the limit members 222.

[0092] Optionally, the fixed support plate 220 and the movable support plate 230 can be made of aluminum material through sandblasting and anodizing, which is light in weight and beautiful in appearance. Figure 5 and Figures 6a to 6cAs shown, the fixed supporting surface and the movable supporting surface are detachable independent parts, both of which have the same shape and are both "V"-shaped, and both the fixed supporting surface and the movable supporting surface are provided with concave-convex patterns, which not only enhance the wear resistance of the supporting surface but also improve the aesthetics, and by arranging the fixed supporting surface and the movable supporting surface as replaceable independent parts, when excessive wear or deformation occurs, they can be easily replaced without replacing the entire support member.

[0093] Furthermore, the adjustable support 200 also includes a second scale 250 arranged parallel to the second track 240, and the second scale 250 indicates the distance of the movable support plate 230 relative to the fixed support plate 220 in the first direction X, so that the movable support plate 230 can be quickly positioned according to the axial size of the workpiece, saving debugging time.

[0094] See also Figure 6a , Figure 6b and Figure 7 To facilitate installation and operation of the movable support plate 230, the lower end of the movable support plate 230 can be fixed on the movable plate 232, and then the movable plate 232 can be fixed on the second slider 242. In this way, since the movable plate 232 can provide a larger installation surface, it can be more conveniently and firmly fixed on the second slider 242. To facilitate moving the movable support plate 230, a handle 234 can also be provided on one side of the movable plate 232, which makes it easier to adjust the position of the movable support plate 230 in the first direction X.

[0095] In addition, if Figure 7 As shown, a scale indicator 246 is also provided on the second slider 242. The scale indicator 246 has a tip portion protruding downward, the tip portion is close to the second scale 250 and is aligned with the central axis of the movable support plate 230 along the first direction X (i.e., the thickness direction of the movable support plate 230), so as to indicate the specific scale of the movable support plate 230 corresponding to the second scale 250. The scale indicator 246 further facilitates the quick and accurate acquisition of the position of the movable support plate 230, thereby facilitating quick and accurate positioning of the movable support plate 230.

[0096] Optionally, limit blocks 248 may be provided at both ends of the second track 240 to limit the displacement stroke of the second slider 242 in the first direction X. In addition, a fourth fastening screw 244 may be provided on the second slider 242 to lock the second slider 242 at different positions of the second track 240 .

[0097] Also, see Figure 2a to Figure 2c and Figure 5 , the tool 100 may also include at least one standard ball mounting hole 108 disposed on the base plate 110. As an example, see Figure 2aAccording to the embodiment of the present disclosure, the tool 100 includes three standard ball mounting holes 108 arranged at equal intervals on the base plate 110 along the first direction X. When in use, the standard ball B can be installed in an appropriate standard ball mounting hole 108 according to actual needs. With this arrangement, when calibrating the stylus, it is not necessary to disassemble the base plate 110 in order to install the standard ball B on the working platform T, but the calibration of the stylus can be performed directly on the base plate 110.

[0098] In summary, the present disclosure provides the above-mentioned universal three-coordinate clamping tool with adjustable fixing components, which can not only adapt to various types and sizes of workpieces to be measured at the same time, but also enable measurement of different workpieces without changing the tooling, thus avoiding the manufacturing cost, time cost and waste of space resources caused by multiple sets of tooling; it can also realize fast and accurate positioning of the workpiece on the tooling, thereby allowing any type of workpiece to be switched quickly at any time, and can also avoid re-alignment and establishment of the tooling coordinate system; furthermore, the tooling can be fixed on the detection table for a long time, firmly clamps the workpiece without blocking the measured part of the workpiece, and prevents interference between the probe and other structures during measurement, thereby reducing the programming difficulty, simplifying the measurement procedure, and reducing measurement errors.

[0099] Specifically, the three-coordinate universal combined tooling disclosed in the present invention also has at least the following advantages:

[0100] The top surface of the first sliding block is always flush with the upper surface of the substrate, ensuring that when different workpieces are fixed on the substrate, the central axis direction is parallel to the first direction and is in a horizontal plane, thereby ensuring measurement accuracy.

[0101] Since the first guide rail mechanism and the second guide rail mechanism adopt roller linear guide rails, compared with ordinary sliding guide rails, the adjustment of the stroke of the first slider and the second slider is easier and more labor-saving.

[0102] The positioning pin head is cylindrical and the moving pin head is diamond-shaped, which ensures the precise positioning of the workpiece on the one hand and reduces the difficulty of assembling and disassembling the workpiece on the other hand.

[0103] By providing a first ruler arranged along the first track, a second ruler arranged along the second track, and a scale indicator, the movable pin or the movable support plate can be quickly and accurately positioned according to the axial size of the workpiece, saving debugging time.

[0104] By providing a plurality of fastening screws, the requirements for the dimensional accuracy of the shaft-hole fit and the difficulty of assembly are reduced, and the firmness of positioning and installation can be ensured.

[0105] The base plate can be formed by detachably joining a plurality of base plate parts, which allows the base plate to be expanded as needed according to workpieces of different sizes or models to better adapt to different workpieces.

[0106] The three-coordinate universal combined tooling also includes at least one standard ball mounting hole arranged on the base plate, which allows the stylus to be calibrated without disassembling the tooling.

[0107] By providing an adjustable support with a movable support plate, the three-coordinate universal combined tooling according to the present disclosure can be adapted to workpieces of different models and sizes, even if the workpiece does not have a supporting portion such as a foot.

[0108] The fixed support plate and the movable support plate are aligned in the first direction and the fixed support surface of the fixed support plate and the movable support surface of the movable support plate are at the same height, which ensures that when the second workpiece is placed on the adjustable support, its central axis direction is parallel to the first direction and is in a horizontal plane, thereby ensuring measurement accuracy.

[0109] A retractable limiting member is arranged on the side of the fixed supporting plate opposite to the movable supporting plate, and the workpiece can be accurately positioned by making the end of the workpiece abut against the limiting member.

[0110] The stability of the second guide rail mechanism is improved by providing the limit block and the fourth fastening screw.

[0111] Although the present disclosure describes the three-coordinate universal combination tooling by taking the motor base as an example of the workpiece to be measured, it can be understood that the application of the present disclosure is not limited to the workpiece to be measured, but all workpieces with similar cylindrical structures that require coaxiality measurement.

[0112] The above are only preferred embodiments of the present disclosure. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present disclosure. These improvements and modifications should also be regarded as the protection scope of the present disclosure.
