Description

Technical Field

[0001] The utility model belongs to the technical field of three-coordinate measuring equipment, in particular to an improvement on the structure of a Z-axis balancing device used for a three-coordinate measuring machine. Background Art

[0002] As a high-precision measuring device, the stability of the three-dimensional coordinate measuring machine during operation has a vital impact on ensuring the measuring accuracy of the measuring machine.

[0003] Due to factors such as the working environment and the properties of the measuring machine's own components such as the motor, the measuring machine will generate certain vibrations when in use, and this vibration will be transmitted in the machine.

[0004] The Z axis of the measuring machine is one of the most core three-axis components when the equipment is measuring. Even the slight vibration of its structure will affect the measurement accuracy.

[0005] In order to ensure the accuracy and high precision of the measurement, the influence of vibration on the Z-axis should be minimized as much as possible. Ensuring the working stability of the Z-axis is crucial to ensuring the high precision of the measuring machine.

[0006] The existing Z-axis balancing device is to weld one end of the steel wire rope on the balancing cylinder to a stud, which is screwed and fixed on the top plate of the balancing bracket, and the balancing bracket is fixed on the body of the three-dimensional coordinate measuring machine. The other end of the steel wire rope is connected to the piston assembled on the Z-axis to achieve the effect of balancing the Z-axis.

[0007] The wire rope is fixedly connected to the stud, and the stud is screwed on the balance bracket and rigidly connected to the balance bracket. In this way, when the fuselage vibrates, the vibration will be transmitted to the balance bracket and then to the stud, causing vibration to the balance cylinder connected to the stud and the Z-axis, affecting the accuracy of the Z-axis.

[0008] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In the description of the implementation method, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0050] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0051] In the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0052] The utility model provides an embodiment of a Z-axis balancing device. The Z-axis balancing device is mainly used for balancing a moving Z-axis of a three-coordinate measuring machine to ensure the movement accuracy of the Z-axis.

[0053] Specifically, the Z-axis balancing device in this embodiment mainly includes:

[0054] The balancing bracket 100 is a support frame of the balancing device, which is assembled and fixed on the body of the three-dimensional coordinate measuring machine. In this way, when the body of the three-dimensional coordinate measuring machine vibrates due to the influence of factors such as the external environment, the vibration may be transmitted to the balancing bracket 100 assembled thereon.

[0055] The balancing bracket 100 includes a top member 110 , and a through portion 111 is provided on the top member 110 ;

[0056] The top member 110 constitutes a top plate of the balancing bracket 100 , and the through portion 111 is a through hole provided through the top plate.

[0057] The balancing cylinder 200 is connected to the Z-axis 700 and includes a cylinder body and a piston 210 slidably disposed in the cylinder body.

[0058] The flexible connecting member 300 is connected to the piston 210 of the balancing cylinder 200 .

[0059] The balancing cylinder 200 is mainly used to achieve the balance of the Z-axis 700 , and is assembled and fixed on the Z-axis 700 through a cylinder seat.

[0060] A piston 210 is arranged inside the balancing cylinder 200, and the piston 210 can slide back and forth relative to the cylinder body of the balancing cylinder 200. The flexible connecting piece 300 is correspondingly connected to the piston 210. When the Z axis 700 moves up and down, it will drive the balancing cylinder 200 to move up and down, and then the flexible connecting piece 300 will drive the piston 210 to expand or contract relative to the cylinder body.

[0061] The rigid connection module 400 is assembled in the penetration portion 111 and fixedly connected to the flexible connection member 300 .

[0062] The rigid connection module 400 is vertically arranged in the through portion 111 and both ends thereof extend out of the through portion 111 .

[0063] There is a gap between the rigid connection module 400 and the through-portion 111, so that the rigid connection module 400 does not directly contact the inner wall surface of the top member 110, thereby separating the two, reducing the vibration transmitted to the rigid connection module 400 when the top member 110 vibrates, and avoiding the impact on the Z-axis 700.

[0064] Since the flexible connector 300 is fixedly connected to the rigid connection module 400 assembled in the balancing bracket 100, when the balancing cylinder 200 moves up and down, the flexible connector 300 is fixed at one end, and the other end will pull the piston 210 to move accordingly, so that it matches the up and down movement of the moving Z-axis 700. The effect of balancing the Z-axis 700 is achieved by expanding or contracting the flexible connector 300.

[0065] The rigid connection module 400 is assembled on the rigid balancing bracket 100. The balancing bracket 100 is fixed to the fuselage. When the fuselage is vibrated, the vibration force will be transmitted to the balancing bracket 100, and then transmitted to the top component 110 constituting the balancing bracket 100, and then transmitted to the flexible connection 300 and the balancing cylinder 200 through the rigid connection module 400, and further transmitted to the Z-axis 700. When the Z-axis 700 is affected by the vibration during movement, it will affect the movement accuracy and operation stability of the Z-axis 700, and further affect the measurement accuracy of the Z-axis 700.

[0066] In order to prevent the vibration of the fuselage from being directly transmitted to the balancing cylinder 200 and the Z-axis 700 through the rigid connection module 400 , a buffering and shock absorbing module 500 is provided between the position where the rigid connection module 400 and the top member 110 may contact and cooperate.

[0067] Specifically, the rigid connection module 400 includes: two locking kits 410 , which are respectively located at the top and bottom of the top member 110 .

[0068] Each of the locking kits 410 includes an extension portion 411 , wherein the top extension portion 411 is parallel to the top surface of the top member 110 , and the bottom extension portion 411 is parallel to the bottom surface of the top member 110 ;

[0069] The two locking kits 410 are respectively arranged at the top and bottom positions of the rigid connection module 400. When the rigid connection module 400 is assembled inside the through-portion 111, the extension portion 411 of one of the locking kits 410 is located at the upper position of the top member 110, and the other locking kit 410 is located at the bottom position of the top member 110.

[0070] The extension portion 411 on the locking assembly 410 can ensure that the rigid connection module 400 will not fall out of the through portion 111 .

[0071] An installation space is formed between the extension portions 411 of the two locking kits 410 arranged vertically and the top member 110 , and the buffer and shock absorbing module 500 is disposed inside the installation space.

[0072] There are two buffering and shock absorbing modules 500, which are respectively arranged between the top surface of the top member 110 and the top extension part 411, and between the bottom surface of the top member 110 and the bottom extension part 411, so as to separate the top member 110 from the rigid connection module 400 and reduce the vibration transmitted to the top member 110.

[0073] By simultaneously arranging the buffering and shock absorbing modules 500 between the top surface of the top member 110 and the top extension portion 411 and between the bottom surface of the top member 110 and the bottom extension portion 411, it can be ensured that the vibration transmitted from the fuselage can be buffered and reduced at the top and bottom positions where the top member 110 may contact the rigid connection module 400. The buffering and shock absorbing modules 500 can reduce the vibration transmitted to the rigid connection module 400, so as to reduce the vibration transmitted from the top member 110 to the rigid connection module 400 as much as possible, thereby reducing the influence on the Z-axis 700 connected to the balancing cylinder 200, thereby ensuring the stability of the movement of the Z-axis 700 and the working accuracy of the Z-axis 700.

[0074] In some embodiments of the present application, a receiving cavity 120 is formed inside the balancing bracket 100 , and the balancing cylinder 200 and the Z-axis 700 are both built inside the receiving cavity 120 .

[0075] The balancing bracket 100 further includes a balancing side plate connected to the periphery of the top member 110 , and the accommodating cavity 120 is formed by the balancing side plate and the top member 110 .

[0076] By integrating the balancing cylinder 200 and the Z-axis 700 into the balancing bracket 100, not only can the external space occupied by the entire balancing device be reduced and space can be saved, but the balancing structure of the balancing cylinder 200 can also be shielded by the balancing bracket 100 to ensure the overall aesthetics.

[0077] In some embodiments of the present application, the rigid connection module 400 includes: a rigid adjustment member 420 having an external thread formed on the outside thereof and penetrating through the penetrating portion 111;

[0078] The rigidity adjustment member 420 is a rigidity adjustment stud, which is assembled in the through hole.

[0079] Two locking sets 410 are respectively mounted on the rigid adjustment member 420 near two ends;

[0080] There are two clamping components 430 , which are screwed on both ends of the rigid adjustment member 420 to clamp and fix the locking kit 410 at the top and bottom.

[0081] The clamping component 430 is a clamping nut, two of which are arranged at both ends of the rigid adjustment member 420 . By screwing the clamping nut, force can be applied to the extension portion 411 to clamp the locking kit 410 onto the buffer and shock absorbing module 500 .

[0082] In some embodiments of the present application, the locking kit 410 includes:

[0083] The locking sleeve body 412 is sleeved on the rigid adjusting member 420 and at least partially located in the through-portion 111 , and its axis is parallel to the axis of the rigid adjusting member 420 ;

[0084] The extension portion 411 is arranged along the circumference of the locking sleeve body 412 and is perpendicular to the axis of the locking sleeve body 412 . The extension portions 411 of the two locking sleeves 410 are parallel to each other.

[0085] In some embodiments of the present application, the inner diameter of the through-portion 111 is set to be larger than the outer diameter of the locking sleeve body 412. When the rigid connection module 400 is assembled in the through-portion 111, there is a distance between the outer side surface of the locking sleeve body 412 and the inner wall of the through-portion 111. In this way, the rigid connection module 400 does not contact the inner wall surface of the top member 110. When the top member 110 vibrates, the vibration will not be transmitted to the rigid connection module 400, thereby avoiding the influence on the Z-axis 700.

[0086] The extension portion 411 of the locking kit 410 and the top member 110 are buffered and damped by the buffering and damping module 500 to reduce the vibration transmitted to the Z-axis 700 .

[0087] In some embodiments of the present application, the buffer and shock absorbing module 500 includes: a first buffer and shock absorbing member 510, which is arranged parallel to the extension portion 411 and fits the extension portion 411, is sleeved on the locking sleeve body 412, and has a distance between the first buffer and shock absorbing member 510 and the locking sleeve body 412;

[0088] The second buffer and shock absorbing component 520 is sleeved on the locking sleeve body 412 and has a distance from the locking sleeve body 412 , and is respectively fitted with the first buffer and shock absorbing component 510 and the top member 110 .

[0089] For the convenience of description, the present embodiment is described by taking the buffering and shock absorbing module 500 disposed at the top position of the top member 110 as an example.

[0090] At this time, the first buffering and shock absorbing member 510 is arranged at a position below the extending portion 411 , and the second buffering and shock absorbing member 520 is arranged at a position between the top surface of the top member 110 and the first buffering and shock absorbing member 510 .

[0091] In order to prevent the rigid connection module 400 from being separated from the through-portion 111 , the second buffer and shock-absorbing member 520 is at least configured to have an outer diameter greater than an inner diameter of the through-portion 111 .

[0092] In this way, the vibration transmitted to the top member 110 will be transmitted to the second buffer shock absorber 520 for buffering and shock absorption, and then transmitted to the first buffer shock absorber 510 for buffering and shock absorption, and finally transmitted to the extension portion 411. After the double buffering and shock absorption effect of the first buffer shock absorber 510 and the second buffer shock absorber 520, the vibration transmitted to the rigid connection module 400 is greatly reduced.

[0093] Furthermore, when the first buffer shock absorber 510 and the second buffer shock absorber 520 are mounted on the locking sleeve 410, they are not in direct contact with the locking sleeve 410, but have a distance with the locking sleeve body 412, thereby preventing the first buffer shock absorber 510 and the second buffer shock absorber 520 from directly contacting the locking sleeve body 412 and transmitting vibration to the locking sleeve body 412 and then to the rigid connection module 400 and the Z-axis 700.

[0094] In some embodiments of the present application, the first buffering shock absorbing member 510 is a first buffering shock absorbing rubber sheet or an elastic gasket, and the second buffering shock absorbing member 520 is a second buffering shock absorbing rubber sheet or an elastic gasket.

[0095] The cushioning and shock absorbing rubber sheet or elastic sheet can achieve the cushioning and shock absorbing effect. Of course, the first cushioning and shock absorbing component 510 and the second cushioning and shock absorbing component 520 can also be made of cushioning foam and other materials with elastic cushioning effect, and no specific limitation is made here.

[0096] In some embodiments of the present application, a through cavity 421 is formed inside the rigid adjustment member 420 and penetrates the rigid adjustment member 420 , and a spherical socket 422 is formed at the bottom of the through cavity 421 ;

[0097] The resetting and balancing component 600 is disposed in the through cavity 421 . A spherical adjusting portion 610 matching the shape of the spherical socket 422 is formed at the bottom of the resetting and balancing component 600 . The resetting and balancing component 600 is connected and fixed to the flexible connector 300 .

[0098] The flexible connector 300 is connected to the balancing cylinder 200, and the balancing cylinder 200 is connected to the Z-axis 700. When the Z-axis 700 moves up and down, the position may be offset, driving the flexible connector 300 to swing or when subjected to an external force, the flexible connector 300 may swing. When the flexible connector 300 swings, the resetting balancing component 600 connected to the flexible connector 300 can rotate relative to the spherical socket 422 through the spherical adjusting portion 610 to adapt to the position change of the flexible connector 300.

[0099] After the swing force is eliminated, since the spherical adjusting portion 610 is at the bottom and has a large weight, it will return to its original position under the action of its own weight, so that the flexible connecting member 300 returns to the vertical position;

[0100] The spherical adjusting portion 610 can also automatically adjust the verticality so that the flexible connecting member 300 always remains in a vertical position.

[0101] In some embodiments of the present application, the resetting and balancing component 600 includes: a balancing body portion 620 , which is vertically arranged in the through cavity 421 ;

[0102] And a transition connection portion 630 is connected between the spherical adjustment portion 610 and the balancing main body portion 620 , and the outer diameter of the transition connection portion 630 gradually decreases from a direction close to the spherical adjustment portion 610 to a direction away from the spherical adjustment portion 610 .

[0103] The balancing body portion 620 is a balancing body rod, and its outer diameter is less than or equal to the minimum outer diameter of the transition connection portion 630 .

[0104] The maximum outer diameter of the transition connection portion 630 is smaller than or equal to the outer diameter of the spherical adjustment portion 610 .

[0105] The spherical adjusting portion 610 is arranged to have a larger outer diameter than the balancing main body 620 so that the entire resetting balancing component 600 can be automatically reset after being subjected to force.

[0106] In some embodiments of the present application, an insertion cavity is formed in the reset balancing component 600, the insertion cavity is arranged through the reset balancing component 600, and the flexible connector 300 is inserted in the insertion cavity and fixedly connected to the reset balancing component 600. The insertion cavity is arranged through the reset balancing component 600 from top to bottom along the height direction of the reset balancing component 600.

[0107] In some embodiments of the present application, the resetting and balancing component 600 is a rigid component, the flexible connecting component 300 is a steel wire rope, and the flexible connecting component 300 is fixed to the resetting and balancing component 600 by welding.

[0108] The steel wire rope passes through the rear end of the reset balancing component 600 from bottom to top and is welded and fixed to the reset balancing component 600 to achieve connection between the two.

[0109] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
