[0039] In the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0040] In some embodiments of the present application, a standard ball placement bracket for a measuring machine is provided, comprising:

[0041] A fixed seat 100, above which an interface plate 220 for placing a standard ball is provided;

[0042] In some embodiments, the fixing base 100 is used to support and fix the interface plate 220 , a carbon fiber support rod 210 is connected between the fixing base 100 and the interface plate 220 , and the interface plate 220 is arranged on the carbon fiber support rod 210 .

[0043] When connecting, the end of the carbon fiber support rod 210 is polished and flat, one end is bonded to the fixing seat 100 through epoxy 2014, and the other end is bonded to the interface plate 220. After bonding, the whole is cured for at least 6 hours to ensure that the bonding part is firm.

[0044] The interface plate 220 is provided with a connection interface for installing and fixing a standard ball. The interface plate 220 adopts the existing interface plate 220 structure to ensure its versatility by adapting to different types of standard balls.

[0045] The support member 300 is arranged below the fixing base 100 and connected to the bottom of the fixing base 100;

[0046] In some embodiments, the support member 300 is a central rod, which is connected to the bottom of the fixing base 100 and is disposed vertically to the fixing base 100 .

[0047] A sliding component 400 slidably disposed on the support member 300 ;

[0048] In some embodiments, the sliding component 400 is a slider that can slide up and down along the supporting member 300 to change its position.

[0049] The support arm module 500 is provided with multiple groups, which are arranged around the circumference of the connecting member 700, and have a rotating connection end 550 at both ends, which is rotatably connected to the fixed base 100. It is rotatably connected to the fixed base 100 so that it can rotate relative to the fixed base 100 to open a certain angle.

[0050] The supporting end 560 is used to achieve support.

[0051] The invention comprises: a plurality of support rods 510 arranged in parallel, wherein the support rods 510 are carbon fiber rods;

[0052] In some embodiments, two support rods 510 are provided and arranged in parallel. When connected, one end of the two support rods 510 is rotatably connected to the fixing base 100 .

[0053] Setting the support rod 510 as a carbon fiber rod can greatly reduce the weight of the support arm module 500 while ensuring the support strength.

[0054] The original standard ball placement bracket uses steel support columns, and the bottom plate uses a thick plate to ensure the stability of the bottom, and is fixed to the base with bolts. It weighs about 18.72Kg and is difficult for people to move during use, and is difficult to transport and disassemble.

[0055] Multiple groups of support arm modules 500 are arranged, and all adopt the structure of carbon fiber pipes, which reduces the overall weight of the bracket to about 8Kg, a reduction of about 57%, greatly reducing the weight of the overall device. The reduced weight also correspondingly improves the mobility of the standard ball placement bracket, which can be moved conveniently and flexibly.

[0056] The hinge seat 520 is slidably connected to the plurality of support rods 510;

[0057] The connection footing module at least includes: a suction cup footing module 600, a magnetic footing module and a bolt footing module, wherein one of the suction cup footing module 600, the magnetic footing module and the bolt footing module is selectively installed on the support end 560;

[0058] When the suction cup foot module 600 is selected, the support arm module 500 can be sucked and fixed to the measuring table of the measuring machine by means of the suction cup 620 .

[0059] When the magnetic foot module is selected, the support arm module 500 can be fixed to the measuring table of the measuring machine by magnetic attraction.

[0060] The support arm module 500 can be fixed to the measuring table of the measuring machine by means of bolt locking and fixing via the bolt base module.

[0061] When the connecting base module is set up, it is set into three module structures: a suction cup base module 600, a magnetic base module and a bolt base module. When in use, the user can choose one of the suction cup base module 600, the magnetic base module or the bolt base module to install at the support end 560 according to the needs of the actual use environment, so as to achieve support and fixation of the entire standard ball placement bracket.

[0062] The setting of a variety of different foot modules makes it convenient for users to choose according to actual use needs, quickly change the fixing method, and flexibly apply to various table structures such as flat marble surface, metal surface, ordinary base 910, etc., fully meeting the use requirements of various measuring machines such as bridge measuring machine, horizontal arm measuring machine, gantry measuring machine, etc.

[0063] A plurality of connecting members 700 are provided, one end of each of the connecting members 700 is respectively hinged to the plurality of articulated seats 520 of the plurality of supporting arm modules 500 , and the other end of each of the connecting members 700 is hinged to the sliding member 400 .

[0064] In some embodiments, the connecting member 700 is a connecting rod for connecting the sliding component 400 and the hinge seat 520 .

[0065] In some embodiments, a sliding protrusion 410 is formed on the sliding component 400, and a connecting U-shaped member 710 is formed at the end of the connecting rod. The sliding protrusion 410 is inserted into the U-shaped member 710 and is rotatably connected to the U-shaped member 710 through a connecting shaft.

[0066] The sliding limit portion 310 is formed on the support member 300 and is used to limit the upward sliding position of the sliding component 400 .

[0067] When it is necessary to fix the standard ball placement bracket, the standard ball placement bracket can be unfolded first. When unfolding, the sliding component 400 is slid upward, and the sliding component 400 applies force to the hinge seat 520 hinged to it through the connecting piece 700, and applies force to the support rod 510 through the hinge seat 520, so that it moves outward and unfolds. When the support rod 510 is unfolded, the hinge seat 520 also slides along the support rod 510 accordingly, and finally the opening of multiple support rods 510 corresponding to the multiple support arm modules 500 is realized.

[0068] After the sliding component 400 slides to a certain position, it will be limited by the sliding limiter 310 on the support member 300. At this time, the plurality of support arm modules 500 are also correspondingly unfolded to the connection position with the measuring table of the measuring machine.

[0069] After the support arm module 500 is unfolded into place, the support end 560 of the support arm module 500 is fixed to the measuring table of the measuring machine through the connecting base module at the bottom support end 560 of the support arm module 500, thereby achieving the fixation of the standard ball placement bracket.

[0070] By configuring the sliding component 400 to be connected to multiple support arm modules 500 through multiple connecting members 700 and to slide up and down along the support member 300, the sliding component 400 can simultaneously drive multiple support rods 510 of the multiple support arm modules 500 to extend and retract synchronously when sliding, and by providing a sliding limit portion 310, the multiple support arm modules 500 can be quickly unfolded to the connection position with the measuring table, and the entire bracket unfolding operation is convenient and quick.

[0071] In addition, since the plurality of support arm modules 500 can be extended or retracted under the drive of the sliding component 400, the support arm modules 500 can be quickly deployed to support and fix the entire standard ball placement bracket when in use;

[0072] When not in use, the sliding component 400 can slide to drive the support arm module 500 to retract for storage, thereby reducing the occupation of external space.

[0073] In some embodiments, the sliding limiting portion 310 is formed as a sliding limiting protrusion on the support member 300 , and is used to limit the sliding component 400 .

[0074] In some embodiments, the sliding limit portion 310 is a sliding limit sleeve mounted on the support member 300, and is made of a rubber pad to cushion the impact of the sliding component 400 on the support member 300 when the support arm module 500 is quickly extended.

[0075] In some embodiments, a threaded segment is provided on the support member 300, an external thread is provided on the threaded segment, and an internal threaded hole is provided at the bottom of the fixing seat 100. When fixing, the threaded connection and fixation between the support member 300 and the fixing seat 100 can be achieved by screwing the threaded segment on the support member 300 into the internal threaded hole at the bottom of the fixing seat 100.

[0076] By screwing the support member 300, its position relative to the fixed seat 100 can be adjusted to achieve the up and down position adjustment of the support member 300. When the position of the support member 300 changes, the position of the sliding limit part 310 above it will be driven to change, thereby changing the position of the limit of the sliding component 400 to change the opening angle of the multiple support rods 510. By adjusting the support member 300 to change the position of the sliding limit part 310, the bottom of the multiple support arm modules 500 is finally kept in contact with the measuring table of the measuring machine, ensuring the firmness of the connection between the entire standard ball placement bracket and the measuring table.

[0077] In some embodiments of the present application, the support arm module 500 includes:

[0078] A rotatable connection seat 530 connected to the end of the support rod 510, wherein the rotatable connection seat 530 is rotatably connected to the fixed seat 100 via a rotating shaft;

[0079] In some embodiments of the present application, an avoidance groove 110 is formed on the fixing seat 100 , and the rotating connection seat 530 is arranged in the avoidance groove 110 and is rotatably connected at both ends through a rotating shaft and a side wall of the avoidance groove 110 .

[0080] When the supporting arm module 500 is acted upon by the connecting member 700 , the connecting seat 530 can be rotated and unfolded relative to the fixing seat 100 .

[0081] The support base 540 is connected to the end of the support rod 510 , and an interface portion 541 for connecting to the base module is formed on the support base 540 .

[0082] When the support arm module 500 is deployed in place, it is supported by the support base 540. The interface portion 541 can be used to connect with the connection foot module.

[0083] In some embodiments of the present application, lugs 521 are formed at both ends of the hinge seat 520, a receiving space is formed between the two lugs 521, and an insertion hole 522 is formed on each lug 521;

[0084] The end of the connecting member 700 is connected to a transverse connecting rod 720 . The transverse connecting rod 720 is arranged in the accommodating space, and both ends extend into the insertion holes 522 of the corresponding sections.

[0085] The connecting member 700 is rotated relative to the insertion hole 522 through the transverse connecting rod 720 at the end, so as to realize the rotation of the connecting member 700 relative to the hinge seat 520.

[0086] In some embodiments of the present application, a protrusion 542 is formed on the support seat 540 , and a slope 5421 is formed on the top surface of the protrusion 542 ;

[0087] The support rod 510 is inserted and fixed in the protruding portion 542 and is perpendicular to the inclined surface 5421 .

[0088] The protrusion 542 on the support seat 540 is used to connect and fix with the support rod 510.

[0089] The top surface of the protrusion 542 is set as an inclined surface 5421 and is perpendicular to the support rod 510, mainly for adapting to the inclined support rod 510 to ensure that the bottom surface of the support seat 540 can horizontally fit the measuring table of the measuring machine.

[0090] In some embodiments of the present application, the interface portion 541 is a threaded interface hole formed on the support base 540 on one side of the protrusion 542 .

[0091] The suction cup foot module 600 includes: a suction cup connector 610, which passes through the threaded interface hole and has an external thread on its outer side;

[0092] A suction cup 620 connected to the bottom of the suction cup connector 610;

[0093] The locking nut assembly includes an upper locking nut 630, which is used to be screwed onto the suction cup 620 connector 700 at a position above the threaded interface hole to be pressed against the top surface of the support seat 540;

[0094] The lower locking nut 640 is used to be screwed onto the suction cup 620 connector 700 at a position below the threaded interface hole to abut against the bottom position of the support base 540.

[0095] The upper locking nut 630 and the lower locking nut 640 are respectively screwed on the top surface of the support seat 540 and the bottom surface of the support seat 540 to fix the suction cup connector 610, thereby fixing the suction cup 620 fixed to the suction cup connector 610.

[0096] The suction cup 620 can be fixed on the measuring table by its own deformation or the negative pressure of the inner cavity of the vacuum pump stroke. After adsorption, it can ensure that the standard ball placement bracket is stable and firm in the vertical direction without deviation.

[0097] In some embodiments of the present application, the magnetic base 910 module includes a threaded connector 700 for screwing and fixing in the threaded interface hole and a magnetic base connected to the threaded connector 700 .

[0098] The threaded connector 700 is a screw, which is screwed and fixed in the threaded interface hole to fix it and its magnetic base to the support end 560 of the support arm module 500. The magnetic base can be attracted to the metal plate of the measuring table to achieve adsorption and fixation.

[0099] The magnetic seat can be selected from a seat body structure with a magnet embedded inside, which can be adsorbed by the magnet.

[0100] In some embodiments of the present application, the bolt foot module includes: a connecting bolt, which is used to be screwed into the threaded interface hole and screwed into the measuring table of the measuring machine to fix the standard ball placement bracket.

[0101] When the flatness is not good and the vacuum suction cup 620 is not suitable for fixing, the entire bracket can be directly fixed with bolts using connecting bolts.

[0102] A locking hole is provided on the measuring table. When fixing, the end of the connecting bolt is screwed and fixed in the locking hole.

[0103] In some embodiments of the present application, a limiting component 800 is provided on the fixing seat 100 for limiting the rotational opening position of the support rod 510 .

[0104] The limiting component 800 is a limiting pin, which is fixed on the fixed seat 100, and limits the rotating limiting seat, thereby limiting the rotating open position of the support rod 510, and performing secondary restriction on the extension freedom of the support arm module 500, and cooperating with the sliding limiting part 310 to ensure that the support arm module 500 is unfolded into place.

[0105] In some embodiments of the present application, a threaded connection hole 320 is provided at the bottom of the support member 300 .

[0106] The support stud is optionally screwed into the threaded connection hole 320.

[0107] The standard ball placement bracket receives a relatively small touch force during actual calibration, and the overall structure can ensure the stability of the interface board 220 .

[0108] In order to prevent the vacuum suction cup 620 from becoming loose due to accidental failure of the standard ball placement bracket, a threaded connection hole 320 is provided at the bottom of the support member 300. To ensure strength, a support stud can be screwed into the threaded connection hole 320. After the suction cup 620 is adsorbed, the support stud is rotated to make it descend until it completely touches the ground and is tightened with a torque wrench. This can make the entire standard ball placement bracket rise as a whole, further enhancing the overall stability.
