Description

Technical Field

[0001] This utility model belongs to the field of vehicle coordinate measuring technology, and in particular relates to a coordinate measuring bracket. Background Technology

[0002] Currently, during the development of new models, OEMs typically need to weld on coordinate measuring machine (CMM) brackets to support and spatially position the parts to be measured in order to ascertain their accuracy. In some cases, each CMM needs to be independently installed for each model. However, the development cost of these CMM brackets is relatively high, and their versatility is poor. Furthermore, their usage frequency decreases significantly once mass production begins, leading to issues such as encroachment on factory space.

[0003] Currently, most coordinate measuring machine (CMM) supports are horizontal structures (as disclosed in document CN216246193U, "Flexible Coordinate Measuring Support"), which allow the part to be measured to be placed flat on the CMM support. However, when the part to be measured is a vehicle opening and closing part (such as sheet metal parts of doors, hoods, and trunk lids), it has a large enclosed area. If it is placed horizontally on the CMM support, it is difficult to place it accurately on the CMM support, which will affect the measurement accuracy. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a three-coordinate measuring bracket with simple structure and good versatility.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A coordinate measuring machine support includes a base, a support plate, and multiple telescopic support members. The base is horizontally arranged, and the support plate is arranged on the base in the front-to-back direction. The left or right side of the base is used to place the part to be measured in the front-to-back direction. The multiple telescopic support members are detachably installed on the corresponding side of the support plate in the left-to-right direction. The telescopic ends of the telescopic support members are away from the support plate, and are used to support the part to be measured above the base to a vertical position and to position the part to be measured in space.

[0006] The beneficial effects of this utility model are as follows: When performing coordinate measuring machine (CMM) measurement on any type of workpiece, multiple telescopic support members can be accurately installed in the left-right direction at the pre-set positions on the support plate. Then, the telescopic amount of each telescopic support member is adjusted according to the pre-set telescopic amount. The workpiece to be measured is then placed vertically on the upper side of one side of the base in the front-back direction. Finally, the telescopic end of each telescopic support member is connected or supported to the pre-set connection position on the workpiece to be measured. At this time, the workpiece to be measured is accurately positioned in the three-dimensional space above the corresponding side of the base. Subsequently, the workpiece to be measured can be directly measured using a coordinate measuring machine according to the predetermined measurement process.

[0007] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the support plate is installed at the center of the base in the left-right direction.

[0008] The beneficial effect of the above-mentioned further technical solution is that the upper end of the base has a measurement station on each of the left and right sides of the support plate, that is, the entire coordinate measuring machine can simultaneously provide measurement for two parts to be measured.

[0009] Furthermore, the support plate includes a frame and a bearing plate, the frame is disposed on the base, the bearing plate is disposed on the frame, and the bearing plate is used to install the telescopic support member.

[0010] The beneficial effect of the above-mentioned further technical solution is that by setting up a frame, the structural strength of the entire supporting plate is high.

[0011] Furthermore, each of the bearing plates is provided with a plurality of mounting male parts in a matrix arrangement, and a mounting female part is provided at one end of the telescopic support away from its telescopic end. The mounting male parts and the mounting female parts are detachably connected or the mounting male parts and the mounting female parts are paired and connected by a connector.

[0012] The beneficial effect of the above-mentioned further technical solution is that it makes the multiple mounting parts on each of the bearing plates similar to coordinate points in a quadrant, thus making it more convenient and faster to install the telescopic support on the bearing plate.

[0013] Furthermore, the telescopic support also includes a telescopic component, a support plate, and a magnetic column. One side of the support plate is perpendicularly connected to the telescopic end of the telescopic component. The mounting nut is located at the end of the telescopic component opposite to its telescopic end. The support plate is made of a magnetic material, and the magnetic column is magnetically attracted to the side of the support plate opposite to the telescopic component.

[0014] The beneficial effect of the above-mentioned further technical solution is that the magnetic column can be accurately installed on the corresponding support plate according to the preset position, and the magnetic column is magnetically connected to the position corresponding to the part to be measured. In this way, it can not only prevent the part to be measured from falling to the side, but also accurately position the part to be measured in space.

[0015] Furthermore, the support plate has grid coordinate lines on the side opposite to the telescopic member, and / or the telescopic support member further includes a displacement measuring element, which is installed on the telescopic member and is used to measure the telescopic amount of expansion and contraction.

[0016] The beneficial effects of the above-mentioned further technical solutions are as follows: by setting grid coordinate lines on the support plate, the support plate can also form a planar coordinate system, so as to facilitate the precise and quick installation of the magnetic column position; the telescopic support is provided with a displacement measuring device, so that the telescopic support can be precisely and quickly measured by the displacement measuring device.

[0017] Furthermore, the telescopic component includes a sleeve, a rod body, and a locking component. The sleeve is hollow inside, and one end of the rod body passes through one end of the sleeve and is slidably connected to the sleeve. The end of the rod body outside the sleeve constitutes the telescopic end of the telescopic component. The locking component is disposed on the sleeve and is used to lock the rod body relative to the sleeve at the corresponding telescopic amount, or to unlock the rod body relative to the sleeve.

[0018] The beneficial effect of the above-mentioned further technical solution is that the telescopic length of the telescopic component can be adjusted manually as needed, and the telescopic component can be locked by the locking component after the length is adjusted to the correct position.

[0019] Furthermore, the mounting male part includes connecting holes that penetrate the bearing plate from the left and right, and the mounting female part includes a first threaded hole recessed on the telescopic member. The connecting holes are aligned with the first threaded hole and allow the connecting member to pass through, so that the connecting member is threadedly connected to the first threaded hole.

[0020] The beneficial effect of the above-mentioned further technical solution is that it allows the telescopic support to be quickly bolted to the support plate via the connector.

[0021] Furthermore, the mounting male part also includes a positioning male part disposed on the support plate, the connecting hole being located on the positioning male part, and the mounting female part also includes a positioning female part cooperating with the positioning male part, the first threaded hole being disposed on the positioning female part, the positioning female part abutting with the positioning male part to perform circumferential positioning of the telescopic support member and align the connecting hole with the first threaded hole.

[0022] The beneficial effect of the above-mentioned further technical solution is that it enables the telescopic support to be accurately positioned in the circumferential direction when installed on the support plate by the cooperation of the positioning male and positioning female parts.

[0023] Furthermore, the positioning male part is a non-circular groove, and the positioning female part is a protrusion; or the positioning male part is a protrusion, and the positioning female part is a non-circular groove.

[0024] The beneficial effect of the above-mentioned further technical solution is that it enables the precise positioning of the telescopic support component in the circumferential direction by interlocking the positioning male and female parts. Attached Figure Description

[0032] Example 1 like Figure 1 , Figure 2 and Figure 10 As shown, this embodiment provides a coordinate measuring machine (CMM) support 10, including a base 1, a support plate 2, and multiple telescopic support members 3. The base 1 is horizontally arranged, and the support plate 2 is arranged on the base 1 in the front-to-back direction. The left or right side of the base 1 is used to place the part to be measured 20 in the front-to-back direction. The multiple telescopic support members 3 are detachably installed on the corresponding side of the support plate 2 in the left-to-right direction. The telescopic ends of the telescopic support members 3 are away from the support plate 2. The telescopic support members 3 are used to support the part to be measured 20 in an upright state above the base 1 and to position the part to be measured 20 in space. When performing coordinate measuring machine (CMM) measurement on any type of workpiece 20, multiple telescopic support members 3 can be precisely installed in the left-right direction at the pre-set positions on the support plate 2. Then, the telescopic amount of each telescopic support member 3 can be adjusted according to the pre-set telescopic amount. Next, the workpiece 20 can be placed on the upper side of one side of the base 1 in the front-back direction. Finally, the telescopic end of each telescopic support member 3 can be connected or supported to the pre-set support position on the workpiece 20. At this time, the workpiece 20 is accurately positioned in the three-dimensional space above the corresponding side of the base 1. Subsequently, the workpiece 20 can be directly measured using a CMM according to the predetermined measurement process.

[0033] The coordinate measuring bracket 10 provided in this embodiment is characterized by its ability to support the measuring part 20 in an upright position, i.e., to be supported and positioned from one side of the measuring part 20. This makes it convenient to use, especially suitable for components with large enclosed areas, such as vehicle opening and closing parts.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the base 1 is a square plate, and the supporting plate 2 is installed in the middle of the base 1 in the left-right direction. The part to be measured 20 is placed on either side of the base 1. This allows the upper end of the base 1 to have a measurement station on each of the left and right sides of the supporting plate 2, meaning that two parts to be measured 20 can be measured simultaneously on the entire coordinate measuring machine bracket 10.

[0035] like Figure 1 As shown, in this embodiment, coordinate reference holes 11 are recessed at the four corners of the upper end of the base 1 (when the base 1 is in a horizontal state, the two coordinate reference holes 11 on the same side can be used by the coordinate measuring machine to construct the three-dimensional coordinate space of the measuring station).

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the supporting plate 2 includes a frame 21 and four bearing plates 22. The frame 21 is vertically mounted on the base 1 along the front-to-back direction. The frame 21 and / or the base 1 together enclose four mounting holes 211 arranged in a matrix. The mounting holes 211 are square holes. The four bearing plates 22 are all square plates. Each mounting hole 211 contains one bearing plate 22 (the bearing plate 22 is vertically mounted in the corresponding mounting hole 211 along the front-to-back direction). The bearing plates 22 are used to mount the telescopic support members 3. This makes the entire supporting plate 2 structurally strong. At the same time, the four bearing plates 22 are similar to the four quadrants of a plane coordinate system, which is beneficial for the precise installation of multiple telescopic support members 3 on the supporting plate 2.

[0037] Specifically, in this embodiment, the front-back direction can be defined as the X-axis direction of the three-dimensional coordinate system, the vertical direction can be defined as the Y-axis direction of the three-dimensional coordinate system, and the left-right direction can be defined as the Z-axis direction of the three-dimensional coordinate system, and a three-dimensional coordinate system can be constructed at the measurement station.

[0038] In this embodiment, the four support plates 22 need to be coplanarly distributed when they are embedded in the four mounting holes 211 (each support plate 22 has two vertically distributed sides and two horizontally distributed sides along the front and back directions). It can be considered that the four support plates 22 are located in the four quadrants of the XY two-dimensional coordinate system.

[0039] like Figures 1-5As shown, in this embodiment, each of the supporting plates 22 has multiple mounting males 221 arranged in a matrix, and the telescopic support 3 has a mounting female 31 at one end away from its telescopic end. The mounting males 221 and the mounting females 31 are detachably connected. This makes the multiple mounting males 221 on each supporting plate 22 similar to coordinate points in a quadrant, making it more convenient and faster to install the telescopic support 3 on the supporting plate 22.

[0040] like Figures 3-8 As shown, the telescopic support 3 in this embodiment further includes a telescopic member 32, a support plate 33, and a magnetic column 34. The middle of one side of the support plate 33 is perpendicularly connected to the telescopic end of the telescopic member 32. The mounting female part 31 is located at the end of the telescopic member 32 opposite to its telescopic end. The support plate 33 is made of a magnetic material, and the magnetic column 34 is magnetically attracted to the side of the support plate 33 opposite to the telescopic member 32. This allows the magnetic column 34 to be precisely installed on the corresponding support plate 33 according to a pre-set position, and the magnetic column 34 is magnetically connected to the support position corresponding to the part to be measured 20. This not only prevents the part to be measured 20 from tipping over but also allows for precise positioning of the part to be measured 20 in space.

[0041] like Figure 7 and Figure 9 As shown, in this embodiment, the support plate 33 has grid coordinate lines 331 on the side opposite to the telescopic member 32. This allows the support plate 33 to also form a planar coordinate system, facilitating precise and quick installation of the magnetic column 34. In this embodiment, the support plate 33 is also a square plate, and the support plate 33 is parallel to the multiple bearing plates 22. Each support plate 33 has two vertically distributed sides and two horizontally distributed sides along the front-back direction. Since the magnetic column 34 is the direct contact and support point between the telescopic support member 3 and the measured part 20, it can be understood that selecting the installation position of the telescopic support member 3 on the support plate 2 is for coarse adjustment of the position of the magnetic column 34 in the XY plane, while adjusting the installation position of the magnetic column 34 on the support plate 33 is for fine adjustment of the position of the magnetic column 34 in the XY plane, and adjusting the telescopic member 32's telescopic extension is for adjusting the position of the magnetic column 34 in the Z direction.

[0042] In this embodiment, the magnetic posts 34 are all cylindrical or cuboid (with two square end faces) and have the same specifications, which can avoid confusion between the magnetic posts 34 on the various telescopic support members 3.

[0043] like Figure 3 , Figure 4 and Figure 8As shown, in this embodiment, the telescopic support 3 further includes a displacement measuring element 35, which is mounted on the telescopic member 32 and is used to measure the telescopic amount of expansion and contraction of the telescopic member 32. This allows the telescopic support 3 to be measured accurately and quickly by the displacement measuring element 35.

[0044] like Figures 3-5 As shown, in this embodiment, the mounting female part 31 can be an "n"-shaped hook plate, and the mounting male part 221 can be a flat hook ring; or conversely, the mounting male part 221 can be a "U"-shaped hook plate, and the mounting female part 31 can be a flat hook ring (e.g., Figure 6 As shown), this allows the telescopic support 3 to be quickly installed and removed from the corresponding mounting part 221, while also limiting the telescopic support 3 in the circumferential direction.

[0045] In this embodiment, if there are measuring stations on both sides of the base 1, then each of the bearing plates 22 needs to be equipped with mounting parts 221 on both sides.

[0046] like Figure 2 and Figure 10 As shown, the coordinate measuring machine support 10 in this embodiment may further include a controller 5 disposed on the base or the frame. The controller 5 is used to electrically connect with the plurality of telescopic support members 3 via flexible conductive wires (which may be helical wires) (specifically, to the displacement measuring member 35). In this embodiment, the controller 5 may be an ARM series microcontroller with digital display function.

[0047] In this embodiment, the telescopic component 32 can also be a telescopic cylinder (which can be a telescopic electric cylinder, a telescopic pneumatic cylinder, or a telescopic hydraulic cylinder). A telescopic cylinder with an anti-rotation function at the telescopic end should be selected (which is an existing product and will not be described in detail here). In this case, the controller 5 is also electrically connected to the telescopic component 32.

[0048] like Figure 4 , Figure 7 and Figure 8As shown, in this embodiment, the telescopic member 32 may further include a sleeve 321, a rod body 322, and a locking member 323. The sleeve 321 is hollow inside, and a through hole 3211 is formed in the middle of one end of the sleeve 321. One end of the rod body 322 passes through the through hole 3211 into the sleeve 321. The through hole 3211 is preferably a non-circular hole. The rod body 322 cooperates with the through hole 3211. A stop block 3221 is provided at one end of the rod body 322 located inside the sleeve 321. The other end of the rod body 322 constitutes the telescopic end of the telescopic member 32 (the maximum outward movement of the rod body 322 relative to the sleeve 321 is such that the stop block 3221 abuts against the end of the sleeve 321 with the through hole 3211). The through hole 3211 can be a regular polygonal hole, preferably a square hole. The cross-section of the rod body 322 perpendicular to its length direction is also square, which can prevent the rod body 322 from rotating relative to the sleeve 321. The sleeve 321 is provided with a second threaded hole 3212 perpendicular to the rod body 322 at the position corresponding to the through hole 3211. One end of the second threaded hole 3212 communicates with the through hole 3211. The locking member 323 is a bolt (such as a wing bolt or a handle bolt). The locking member 323 is threadedly connected to the second threaded hole 3212. Tightening the locking member 323 locks the rod body 322 at the corresponding extension amount. Loosening the locking member 323 releases the rod body 322 from the lock.

[0049] In this embodiment, the displacement measuring element 35 can be a distance measuring probe or a displacement sensor (specifically, it can measure the movement of the support plate 33). When the displacement measuring element 35 is a displacement sensor, it is installed on the telescopic member 32, and its movable end is connected to the side of the support plate 33 near the telescopic member 32. At this time, when the telescopic end of the telescopic member 32 extends and retracts, it will drive the movable end of the displacement measuring element 35 to move synchronously, so as to measure its extension and retraction (the installation method and measurement principle of the displacement measuring element 35 are existing technologies in the field and will not be described in detail here).

[0050] To facilitate recording the positioning scheme of each type of the measured part 20 on the coordinate measuring machine bracket 10, each mounting part 221 can be labeled with a serial number. Simultaneously, the grid frames or intersections of each grid coordinate line 331 on the support plate 33 can also be labeled with serial numbers. Specifically, the installation position of each telescopic support 3 on the support plate 2 (i.e., the serial number of the mounting part 221), the installation position of each magnetic post 34 on the support plate 33 (i.e., the serial number of the corresponding grid frame or intersection), and the elongation of each telescopic component 32 should be recorded. Furthermore, the specific positions of the support points on each type of measured part 20 that are magnetically attracted to multiple telescopic support components 3 should also be recorded. This allows the measured part 20 to be measured not only during the development phase but also periodically or irregularly after production begins (subsequent measurements can be quickly performed by assembling the coordinate measuring machine bracket 10 according to the positioning scheme from the development phase).

[0051] The multiple magnetic columns 34 of the coordinate measuring bracket 10 provided in this embodiment can be flexibly adjusted in the XYZ three-dimensional space, thus it has good versatility.

[0052] This embodiment is mainly intended to provide a versatile coordinate measuring machine bracket 10. However, the measurement method after the measuring part 20 is positioned on the coordinate measuring machine bracket 10 is an existing technology and is not the focus of this embodiment, so it will not be described in detail here.

[0053] like Figure 1 and Figure 2 As shown, in this embodiment, the frame 21 includes three vertical beams 213 and two horizontal beams 212. The three vertical beams 213 are vertically arranged and evenly distributed at the upper end of the base 1 in the front-back direction. One horizontal beam 212 is horizontally arranged at the upper end of the three vertical beams 213 in the front-back direction, and the remaining horizontal beam 212 is horizontally arranged in the middle of the three vertical beams 213 in the front-back direction. At this time, the frame 21 and the base 1 together enclose four mounting holes 211 of the same size.

[0054] In this embodiment, the more dispersed the multiple support points on the measured component 20 are when selected, the better it is for the stability of the measured component 20 supported on the base 1 and the accuracy of subsequent coordinate measuring machine measurements. At the same time, when selecting support points, it is best to ensure that the corresponding magnetic column 34 falls in the exact center of the grid frame or intersection of the corresponding grid coordinate line 331. This is beneficial for recording the specific position of the magnetic column 34 on the corresponding support plate 33.

[0055] The reason why it is necessary to circumferentially limit the telescopic support 3 during installation and prevent the telescopic end of the telescopic support 32 from rotating is to ensure that the grid coordinate lines 331 on the support plate 33 have directionality (there should be no deviation, otherwise it will affect the measurement accuracy and the convenience of using the coordinate measuring bracket 10 to measure the object 20). Specifically, a mark can be made on the side of the upper end of the support plate 33 to ensure that the marked side of the support plate 33 is located at the top when the telescopic support 3 is installed.

[0056] In this embodiment, it is best to select 2-4 support points on the part to be measured 20, and any two support points should not fall into the same quadrant when supporting and positioning (that is, there is at most one telescopic support 3 on each bearing plate 22), so that the stability of the part to be measured 20 when supported on the base 1 is better.

[0057] Specifically, in this embodiment, for any measurement station, a telescopic support 3 can be set on each carrier plate 22. For each carrier plate 22, the position of the corresponding telescopic support 3 is adjustable. For each telescopic support 3, when it is needed, its length can be adjusted to the corresponding length, and when it is not in use, it can be retracted to the reset position. This makes the entire coordinate measuring bracket 10 easier to store and manage (especially to avoid the loss of the telescopic support 3).

[0058] like Figure 1 and Figure 2 As shown, in this embodiment, the lower end of the base 1 can also be provided with multiple feet 12, which makes the base 1 more stable when placed on the ground. In this embodiment, the upper end of the base 1 is provided with a soft pad 13 (which can be a rubber pad or a silicone pad) corresponding to the measurement station, which can prevent the part to be measured 20 from being bumped and deformed on the base 1.

[0059] Example 2 Same as Example 1, except that, as Figure 11 and Figure 12 As shown, in this embodiment, the mounting male part 221 and the mounting female part 31 are paired and connected by a connector 4. Specifically, the connector 4 is a bolt (such as a wing bolt or a handle bolt). The mounting male part 221 includes connecting holes 2211 that penetrate the bearing plate 22 from both sides. The mounting female part 31 includes a first threaded hole 311 recessed in the telescopic member 32. The connecting hole 2211 is aligned with the first threaded hole 311 and allows the connector 4 to pass through, so that the connector 4 is threadedly connected to the first threaded hole 311. This allows the telescopic support member 3 to be quickly bolted to the support plate 2 via the connector.

[0060] Since the connecting hole 2211 passes through both sides of the support plate 22, even if there are measurement stations on both sides of the support plate, it is not necessary to set the mounting part 221 independently on both sides of the support plate 22 (that is, the test stations on both sides share the mounting part 221 on the support plate 2).

[0061] like Figure 11 and Figure 12 As shown, in this embodiment, the mounting male part 221 further includes a positioning male part 2212 disposed on the support plate 22. The connecting hole 2211 is located on the positioning male part 2212. The mounting female part 31 also includes a positioning female part 312 that mates with the positioning male part 2212. The first threaded hole 311 is disposed on the positioning female part 312. The positioning female part 312 abuts against the positioning male part 2212 to perform circumferential positioning of the telescopic support member 3 and to align the connecting hole 2211 with the first threaded hole 311. This allows the telescopic support member 3 to be precisely positioned circumferentially by the cooperation of the positioning male part 2212 and the positioning female part 312 when it is installed on the support plate 2.

[0062] like Figure 11 and Figure 12 As shown, in this embodiment, the positioning male part 2212 is a non-circular groove (it can be a square groove), and the positioning female part 312 is a protrusion; or conversely, the positioning male part 2212 is a protrusion, and the positioning female part 312 is a non-circular groove (such as...). Figure 13 (As shown). This allows the positioning male part 2212 and the positioning female part 312 to be inserted together to achieve precise positioning of the telescopic support 3 in the circumferential direction.

[0063] like Figure 14 and Figure 15 As shown, in this embodiment, if there are measuring stations on both sides of the support plate, each mounting part 221 has two positioning parts 2212 that are relatively distributed on both sides of the bearing plate 22. However, when the two measuring stations are used at the same time, telescopic support members 3 cannot be set on both sides of the same mounting part 221 at the same time (there will be interference between them during installation).

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
