Description

Technical Field

[0001] The utility model belongs to the technical field of measurement and calibration, and in particular relates to a calibration gauge block bracket for a measuring machine. Background Art

[0002] The three-dimensional coordinate measuring machine is a high-efficiency, high-precision, optical-mechanical-electrical-computing universal measuring equipment. It is widely used in the inspection of mechanical parts, the digitization of physical models and the quality control in actual production. It plays an indispensable role in various sectors of machinery manufacturing, instrument manufacturing, electronics industry, automobile industry, aviation and defense industry.

[0003] According to the national standard GB16857.2, measuring machines such as three-dimensional coordinate measuring machines must be calibrated by measuring gauge blocks to verify the accuracy and performance of the machine. When calibrating a three-dimensional coordinate measuring machine, a standard gauge block set is required for calibration. The standard gauge block set is composed of multiple calibrated gauge blocks of different sizes, so a suitable gauge block bracket is required to fix gauge blocks of various specifications.

[0004] The existing gauge block bracket disclosed on the market usually includes a bracket base and a gauge block support plate. A vertically extending support column is arranged on the bracket base, and the support column includes a lower fixed section and an upper adjusting section. The lower fixed section is fixed on the bracket base, and the upper adjusting section is slidably connected with the lower fixed section up and down. A fastening component for positioning the upper adjusting section after it is adjusted into place is arranged on the upper adjusting section or the lower fixed section, and the height adjustment of the gauge block bracket is achieved by sliding the upper adjusting section relative to the lower fixed section; the gauge block support plate is arranged on the top of the upper adjusting section, and a fixed rotating shaft is arranged on the bottom side of the support plate, the fixed rotating shaft is located at the center position of the support plate in the length direction, and is rotatably connected with the upper adjusting section, and an external thread is arranged on the end of the rotating shaft and a nut is installed. When adjusting the angle, the nut is loosened and the gauge block support plate is manually rotated. After rotating a certain angle, the nut is locked.

[0005] Since the gauge block support plate must be able to support gauge blocks of various sizes, and the gauge blocks are of different lengths, the size of the gauge block support plate must be able to provide ample placement space for the largest gauge block, and it must be able to place gauge blocks of various sizes at the same time. This makes the gauge block support plate larger, and the total weight of the gauge block support plate and the gauge blocks larger. The rotating shaft is located at the center of the length of the gauge block support plate, and the nut used to position the rotating shaft and then the gauge block support plate is also installed on the rotating shaft. The gauge block support plate is only supported by the rotating shaft and the upper adjustment section of the support column at the center of its length, resulting in the problem that the existing gauge block bracket is top-heavy and has poor stability, affecting the calibration accuracy.

[0040] In the description of the present invention, 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; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Reference Figures 1 to 9 In some embodiments of the present invention, a measuring machine calibration gauge block bracket 1 is provided, which is used to support a measuring machine calibration gauge block 2. The measuring machine calibration gauge block bracket 1 includes a bracket base 400, an adjustment mechanism 100 and a gauge block support plate 300.

[0043] The support base 400 is height-adjustable and serves as the support base of the entire support. The measuring machine calibration gauge block support 1 is placed or fixed on the measuring platform with the support base 400 .

[0044] The adjustment mechanism 100 includes a fixed support component 120 and an adjustable support component 110. The fixed support component 120 is fixed on the bracket base 400 and is stationary. The adjustable support component 110 is rotatably connected to the fixed support component 120, so that the adjustable support component 110 can rotate relative to the fixed support component 120, thereby changing the position of the adjustable support component 110 and the angle between the adjustable support component 110 and the fixed support component 120 by rotating the adjustable support component 110.

[0045] A support positioning assembly 200 is connected between the adjustable support component 110 and the fixed support component 120, and is used to fix the adjustable support component 110 after the adjustable support component 110 is rotated into place, that is, rotated to a desired angle. The support positioning assembly 200 is located at the opening of the angle formed by the adjustable support component 110 and the fixed support component 120.

[0046] The gauge block support plate 300 is fixed on the adjustable support component 110 and is used to carry the gauge block 2 .

[0047] The principle of adjusting the angle and height of the gauge block bracket 1 and the gauge block 2 of the measuring machine calibration gauge block in the embodiment of the utility model is: rotating the adjustable support component 110 to change the angle between it and the fixed support component 120, thereby changing the angle of the gauge block 2 on the gauge block support plate 300 relative to the horizontal plane; by adjusting the height of the bracket base 400, the height of the gauge block 2 can be changed. Thus, the adjustment of the angle and height of the gauge block 2 is achieved, and the requirements of being able to calibrate different machine models, that is, accuracy compensation, are met, so that the gauge block 2 can cover the measurement space of the machine as much as possible.

[0048] The support and positioning assembly 200 is located at the opening of the angle formed by the adjustable support component 110 and the fixed support component 120, so that the adjustable support component 110, the fixed support component 120 and the support and positioning assembly 200 form an approximately triangular distribution structure. Compared with the solution of locking by tightening the nut at the end of the rotating shaft 130 in the prior art, the support and positioning assembly 200 in the embodiment of the utility model can reliably support the adjustable support component 110, improve the support reliability of the gauge block 2, and help to ensure the calibration accuracy of the measuring machine.

[0049] In some embodiments of the present application, Figures 1 to 3As shown, the bracket base 400 includes a support profile 410 fixedly connected to an L-shaped support base plate 420 on the side of the support profile 410, and the bottom surface of the support profile 410 is flush with the bottom surface of the L-shaped support base plate 420, so that when the entire gauge block bracket 1 is placed or fixed on the measuring platform of the measuring machine, the bottom surface of the support profile 410 and the bottom surface of the L-shaped support base plate 420 can both be in contact with the measuring platform, and the contact area is large, thereby ensuring the stability of the entire gauge block bracket 1; the support profile 410 can be formed by extrusion, and some process structures, such as T-slots and I-slots, can be formed thereon at the same time, so that it can be connected with other components, such as the L-shaped support base plate 420 and the fixed support component 120, by screws. At the same time, the support profile 410 is light in weight and high in strength, thereby improving the structural strength of the entire gauge block bracket 1.

[0050] In some embodiments of the present application, an L-shaped support plate may be provided on only one side of the support profile 410, or may be provided on a group of opposite side portions of the support profile 410, so as to further improve the support reliability.

[0051] The fixed support component 120 is detachably fixed on the top surface of the support profile 410, so that the adjustment mechanism 100 can be separated from the support profile 410, and the height of the bracket base 400 can be changed by replacing the support profile 410 of different heights, thereby achieving the height adjustment of the gauge block 2. The bottom surface of the fixed support component 120 is in close contact with the top surface of the support profile 410, and the contact area is large, which further ensures the stability of the entire gauge block bracket 1.

[0052] It is also possible to configure multiple support profiles 410, stack them up and down, and connect adjacent support profiles 410 detachably via screws, and increase or decrease the number of support profiles 410 to achieve height adjustment of the bracket base 400, thereby achieving height adjustment of the gauge block 2.

[0053] In some embodiments of the present invention, the adjustable support component 110 and the fixed support component 120 are both plate-shaped members, the adjustable support component 110 is located above the fixed support component 120, and one side of the adjustable support component 110 is rotatably connected to the same side of the fixed support component 120 via a rotating shaft 130. Figures 1 to 5 As shown in the perspective, the left side of the adjustable support component 110 is rotatably connected to the left side of the fixed support component 120 through the rotating shaft 130. Accordingly, the adjustment mechanism 100 is arranged at the opening of the angle formed by the adjustable support component 110 and the fixed support component 120, that is, Figures 1 to 5The right side of the adjustable support component 110 and the fixed support component 120 of the viewing angle shown. When the adjustable support component 110 is rotated to the desired angle and fixedly supported by the support positioning assembly 200, the entire adjustment mechanism 100 can maintain a stable structure, thereby stably supporting the gauge block support plate 300 and the gauge block 2.

[0054] In some embodiments of the present invention, the support and positioning components 200 are symmetrically arranged at two locations, respectively located on two adjacent sides of the side where the rotating shaft 130 of the adjustable support component 110 is located. Figures 1 to 5 From the perspective shown, the support and positioning assembly 200 is located at the front and rear sides of the whole formed by the adjustable support component 110 and the fixed support component 120 to further improve the support and positioning reliability of the adjustable support component 110 .

[0055] The support and positioning assembly 200 specifically includes a support rod 210 and a locking component 220. The two ends of the support rod 210 are rotatably connected to the adjustable support component 110 and the fixed support component 120 respectively, and at least one of the two ends of the support rod 210 is slidably connected to the adjustable support component 110 and the fixed support component 120. When the adjustable support component 110 rotates, the support rod 210 is driven to swing; the locking component 220 is used to lock the support rod 210. When the locking component 220 locks the support rod 210, the support and positioning assembly 200 fixedly supports the adjustable support component 110.

[0056] like Figures 1 to 5 As shown, taking one of the support positioning components 200 as an example, a slideway 140, such as a T-shaped slideway, is formed on the adjustable support component 110 and the fixed support component 120, respectively. The extension direction of the slideway 140 is perpendicular to the axial direction of the rotating shaft 130. The two ends of the support rod 210 are rotatably connected to a connecting block 230, and the connecting block 230 has a guide portion that slides with the slideway 140. The guide portion is embedded in the slideway 140. Then, the two ends of the support rod 210 are respectively rotatably connected to the adjustable support component 110 and the fixed support component 120 and are slidably connected, so that when the adjustable support component 110 is rotated, the support rod 210 can be synchronously driven to swing and the two ends slide along the corresponding slideway 140, ensuring that the adjustable support component 110 rotates smoothly. When the adjustable support component 110 rotates to the desired angle, the position is locked by the locking component 220, so that the adjustable support component 110 is maintained at this angle.

[0057] In some embodiments of the utility model, the locking component 220 is a screw, which passes through the end of the support rod 210 and is threadedly connected to the connecting block 230, and the screw is rotatably matched with the end of the support rod 210. When the adjustable support component 110 needs to be rotated, the screw is loosened so that the support rod 210 can swing and slide normally. After the adjustable support component 110 is rotated into place, the screw is then locked to fix the support rod 210 to position and support the adjustable support component 110.

[0058] The structure of the other supporting and positioning assembly 200 is the same as this, and will not be described in detail here. The supporting and positioning assembly 200 of this structural form is simple in structure and easy to operate.

[0059] In some embodiments of the present invention, Figures 1 to 5 As shown, two first arc-shaped recesses 111 are formed on the bottom surface of the adjustable supporting component 110 , and the two first arc-shaped recesses 111 are respectively arranged corresponding to the two ends of the rotating shaft 130 .

[0060] Correspondingly, two second arc-shaped recesses 121 are formed on the top surface of the fixed support component 120, and the two second arc-shaped recesses 121 are respectively arranged opposite to the two first arc-shaped recesses 111 to enclose two cylindrical installation parts corresponding to the two ends of the rotating shaft 130, and the two ends of the rotating shaft 130 pass through the two cylindrical installation parts respectively to be inserted into the cylindrical installation parts. This structure is convenient for the installation of the rotating shaft 130.

[0061] like Figures 1 to 7 As shown, both ends of the rotating shaft 130 are provided with a first stopper 150, and the first stopper 150 applies a radial clamping force to the first arc-shaped recess 111 and the corresponding second arc-shaped recess 121, so that the cylindrical mounting portion surrounded by the first arc-shaped recess 111 and the second arc-shaped recess 121 can reliably wrap the end of the rotating shaft 130, and limit the end of the rotating shaft 130 from radially separating from the cylindrical mounting portion. The first arc-shaped recess 111 and the end of the rotating shaft 130 are in contact through the arc surface, which can ensure that the adjustable support component 110 can be rotated smoothly.

[0062] Furthermore, a second stopper 160 is provided at both ends of the rotating shaft 130, and the second stopper 160 abuts against the corresponding first stopper 150 to limit the rotating shaft 130 from axially disengaging from the cylindrical mounting portion. The first stopper 150 and the second stopper 160 can stably mount the rotating shaft 130 between the adjustable support component 110 and the fixed support component 120 to prevent shaking and misalignment, which is beneficial to avoid shaking of the adjustable support component 110 when it rotates.

[0063] Furthermore, the first stopper 150 is annular and sleeved on both ends of the rotating shaft 130. The adjustable support component 110 and the fixed support component 120 are correspondingly formed with arc-shaped grooves 170 for avoiding the installation of the first stopper 150. The first arc-shaped recess 111 and the second arc-shaped recess 121 both extend toward the side where the arc-shaped recess 170 is located to surround the outer end of the cylindrical installation portion. Figure 6As shown, the first limit member 150 is sleeved on the outer end of the cylindrical mounting portion, and the inner ring surface of the first limit member 150 is a conical surface with a small outer side and a large inner side. The outer ring surface of the cylindrical mounting portion fits closely with the inner wall of the first limit member 150, that is, it is also a conical surface; the first limit member 150 and the outer end of the cylindrical mounting portion cooperate through the conical surface, which can increase the friction between the two. When manually rotating the adjustable support component 110, a certain force is required, and a certain rotation feel can be clearly felt, so that it is easy to control the rotation angle of the adjustable support component 110, especially when a smaller rotation angle is required, it is easy to control and avoid repeated adjustment due to rotation exceeding the required angle.

[0064] Likewise Figure 6 As shown, the second stopper 160 abuts against the end surface of the first stopper 150, specifically located on the outer side of the first stopper 150, and applies an axial extrusion force to the first stopper 150. The first stopper 150 is sandwiched between the second stopper 160 and the cylindrical mounting portion. The second stopper 160 can be a flange formed at both ends of the rotating shaft 130, or a protrusion fixed at both ends of the rotating shaft 130, such as a gasket fixed by screws. In order to further facilitate the installation of the rotating shaft 130, a flange (whose diameter is larger than the diameter of the rotating shaft 130) is formed at one end of the rotating shaft 130 to form the second stopper 160 at one end, and the other end of the rotating shaft 130 is fastened with a gasket by screws to form the second stopper 160 at the other end. The two second stoppers 160 clamp the two first stoppers 150, and can also ensure that the rotating shaft 130 itself does not rotate as the adjustable support component 110 rotates as much as possible.

[0065] Furthermore, the first limiting member 150 corresponding to the end where the second limiting member 160 in the form of a flange is located is also connected to the fixed support component 120 through a pin 180 to ensure its structural stability.

[0066] In order to facilitate the observation of the angle between the adjustable support component 110 and the fixed support component 120, or to accurately grasp the rotation angle of the adjustable support component 110, in some embodiments of the utility model, an angle scale is provided on the outer end face of a first limit member 150, and a pointer 112 is provided on the adjustable support component 110. The pointer 112 cooperates with the angle scale to indicate the rotation angle value of the adjustable support component 110, or to observe the angle between the adjustable support component 110 and the fixed support component 120.

[0067] The pointer 112 can be obtained by engraving or marking on the side surface of the adjustable supporting component 110 .

[0068] For the gauge block support plate 300, as Figures 1 to 3As shown, there are multiple rows of gauge block support frames 500 on it, so as to be able to carry multiple gauge blocks 2 of different sizes at the same time. The arrangement direction of the multiple rows of gauge block support frames 500 is parallel to the rotation axis of the adjustable support component 110, one row of which includes one gauge block support frame 500 for supporting the smallest gauge block 2; the remaining rows include two gauge block support frames 500, and the two gauge block support frames 500 jointly support the corresponding larger gauge blocks 2. The gauge block support frame 500 is provided with a through portion 510 for the gauge block 2 to pass through and a positioning component for positioning the gauge block 2 on the gauge block support frame 500.

[0069] Specifically, the gauge block support frame 500 is box-shaped. Since the gauge block 2 is usually in the shape of a standard rectangular strip, the through portion 510 is a rectangular through hole for the end of the gauge block 2 to be inserted. The positioning component can be a top screw 520 arranged on the periphery of the through portion 510, and the gauge block 2 is positioned by tightening the top screw 520.

[0070] In order to minimize the damage to the gauge block 2, the number of top screws 520 is as small as possible. Preferably, one of them is provided at the top of the gauge block support frame 500. The end of the gauge block 2 is inserted into the through-portion 510, the bottom surface is supported by the bottom wall of the through-portion 510, and the top is tightened and pressed down by the top screw 520. The top screw 520 can be a resin end top screw 520, which can effectively reduce the damage and deformation of the gauge block 2 and extend the service life of the gauge block 2.

[0071] Furthermore, the two gauge block support frames 500 located in the same row each have a support protrusion 530 on the bottom surface of the through portion 510 of each gauge block support frame 500. Figure 1 , Figure 3 and Figure 8 As shown, the support protrusions 530 of the two gauge block support frames 500 are respectively located at the two end force points of the supported gauge block 2. After the two ends of the gauge block 2 are correspondingly inserted into the through-portions 510 of the two gauge block support frames 500, the bottom surface of the gauge block 2 contacts the support protrusions 530, and the contact area is smaller, so it is easier to clamp the gauge block 2 when the top screw 520 is screwed in; at the same time, the two support protrusions 530 are located at the two end force points of the supported gauge block 2, and the gauge block 2 is least deformed under the influence of gravity, which is conducive to improving the calibration accuracy.

[0072] For the gauge block support frame 500 that occupies a row alone, Figure 1 , Figure 3 and Fig. 9 As shown, since it alone supports the gauge block 2 with the smallest length, two supporting protrusions 530 are provided on the bottom surface of the through portion 510, and the two supporting protrusions 530 are respectively located at the two end force points of the supported gauge block 2. Similarly, the supporting protrusions 530 cooperate with the top screw 520 to more easily clamp the gauge block 2, and on the other hand, minimize the deformation of the gauge block 2 under the influence of gravity, thereby improving the calibration accuracy.

[0073] In some embodiments of the present invention, the top end of the supporting protrusion 530 is pointed and the top surface is flat, which further reduces the contact area with the gauge block 2, making the above-mentioned effect of facilitating the clamping of the gauge block 2 more obvious.

[0074] In some embodiments of the present invention, the gauge block support frame 500 is detachably mounted on the gauge block support plate 300, and the gauge block support plate 300 is provided with a plurality of detachable mounting portions for detachably mounting the gauge block support frame 500. In this way, the position of the gauge block support frame 500 can be adjusted at will according to the size of the gauge block 2, thereby improving the flexibility and practicality of the gauge block support frame 1.

[0075] The gauge block support frame 500 can be specifically installed on the gauge block support plate 300 by screws. The detachable mounting portion on the gauge block support plate 300 is a plurality of screw holes 310, so that the screw holes 310 at appropriate positions can be selected to screw the gauge block support frame 500.

[0076] The screw hole 310 can be realized by forming a through hole on the gauge block support plate 300 and embedding a wire screw sleeve. The wire screw sleeve has high thread strength and can avoid thread slippage due to frequent disassembly, thereby extending the service life of the gauge block bracket 1.

[0077] In some embodiments of the utility model, an end limit column 320 is also installed on the gauge block support plate 300, and the end limit column contacts the end surface of the gauge block 2, and can support and limit the gauge block 2 when the inclination angle is large. The end limit column 320 can be a screw, and a plurality of screw mounting holes cooperating with the end limit column 320 are provided on the gauge block support plate 300, and the position of the end limit column 320 can be adjusted according to the size of the gauge block 2, thereby improving flexibility and practicality.

[0078] The gauge block support frame 500 having two supporting protrusions 530 has the smallest size of the gauge block 2 supported by it, and the end of the gauge block 2 may not be exposed outside the gauge block support frame 500, so the corresponding end limit column 320 can be directly formed on the gauge block support frame 500, such as Fig. 9 shown.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
