Description

Technical Field

[0001] This utility model relates to the technical field of large-stroke fully automatic coordinate measuring machines, specifically an adjustable mounting structure for a coordinate measuring machine side cover. Background Technology

[0002] A coordinate measuring machine (CMM) side guard is a protective device installed on the side of a CMM. It is usually made of materials with a certain degree of flexibility and wear resistance, such as nylon, rubber, or thin metal sheet. Its structural design is diverse. Some have adjustable installation functions to adapt to different specifications of equipment, ensuring the high-precision and stable operation of the CMM. At the same time, some side guards also have an aesthetic decoration function.

[0003] In coordinate measuring machines (CMMs), large-stroke models have more stringent requirements for the installation and adjustment of side guards due to their wide measurement range. The side guards need to be stably fixed to prevent displacement during equipment operation, while also possessing flexible clearance adjustment capabilities to adapt to protection and movement requirements under different working conditions. However, the existing side guard installation and adjustment structures of large-stroke CMMs have significant defects:

[0004] On the one hand, the installation process is cumbersome, requiring a large number of auxiliary parts for positioning and fixing, resulting in complex assembly procedures and long time consumption. On the other hand, the adjustment is difficult, making it hard to accurately control the left and right and up and down gaps of the side guards, and after fixing, it is easy to loosen due to vibration or stress, affecting the stability of equipment operation. In addition, the use of too many auxiliary parts not only increases manufacturing costs, but also prolongs production time and reduces overall production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable installation structure for a three-coordinate side guard, which solves the problems in the prior art of cumbersome installation process requiring a large number of auxiliary parts for positioning and fixing, high adjustment difficulty, and difficulty in accurately controlling the left-right and up-down gaps of the side guard.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An adjustable mounting structure for a three-axis side guard includes a marble worktable, a Y-guard connecting plate, a flat washer, a spring washer, a cylindrical hexagonal bolt, a Y-guard support plate, a flat washer, a spring washer, a cylindrical hexagonal bolt, a cylindrical hexagonal bolt, a Y-guard fixing bracket, a spring pin, a side guard clamping block, and a Y-axis side guard.

[0008] The Y-shaped protective cover connecting plate is fixedly installed on the marble workbench by a flat washer, a spring washer, and a hexagonal bolt inside the cylinder.

[0009] The Y-shaped protective cover fixing bracket is fixedly installed on the Y-shaped protective cover connecting plate by flat washer two, spring washer two and hexagonal bolt three inside the cylinder;

[0010] The spring pin is assembled on the side guard clamping block; the side guard clamping block is fixedly installed on the Y guard fixing bracket by a flat washer, a spring washer, and a hexagonal bolt inside the cylinder; the Y-axis side guard is inserted between the side guard clamping block and the Y guard fixing bracket.

[0011] Preferably, the connection structure between the Y-cover fixing bracket and the Y-cover connecting plate can realize the adjustment of the left and right gap of the Y-axis side cover; by loosening or tightening the hexagonal bolts three in the cylinder, the horizontal position of the Y-cover fixing bracket on the Y-cover connecting plate is adjusted, thereby driving the Y-axis side cover to move synchronously, so as to adapt to the accuracy requirements of the left and right gap under different working conditions.

[0012] Preferably, the connection structure between the side cover clamping block and the Y-cover fixing bracket can adjust the vertical gap between the Y-axis side cover; by loosening or tightening the hexagonal bolts 2 inside the cylinder, the vertical height of the side cover clamping block on the Y-cover fixing bracket is changed, thereby adjusting the vertical distance between the side cover clamping block and the Y-cover fixing bracket, and achieving precise control of the vertical gap between the Y-axis side cover.

[0013] Preferably, the connection between the Y-shaped protective cover connecting plate and the marble workbench adopts an anti-loosening structure consisting of a flat washer and a spring washer. The flat washer fits against the surface of the marble workbench, and the spring washer is located between the flat washer and the nut of the hexagonal bolt inside the cylinder. This effectively prevents the hexagonal bolt inside the cylinder from loosening due to vibration during equipment operation, ensuring connection stability.

[0014] Preferably, the connection between the Y-cover fixing bracket and the Y-cover connecting plate, and the connection between the side cover clamping block and the Y-cover fixing bracket, both adopt an anti-loosening structure consisting of a flat washer and a spring washer. The flat washer fits against the surface of the connected parts, and the spring washer is located between the flat washer and the nut of the corresponding bolt. This can prevent the bolts from loosening during long-term operation of the equipment and reduce the wear of the bolts on the surface of the connected parts.

[0015] Preferably, the spring pin and the side cover clamping block are interference fit, and the axis of the spring pin is parallel to the vertical direction of the side cover clamping block. This can position the installation position of the side cover clamping block, ensure the assembly accuracy of the side cover clamping block and the Y-cover fixing bracket, and avoid misalignment after the Y-axis side cover is inserted.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] 1. This utility model utilizes a modular assembly design, directly fixing the Y-shaped protective cover connecting plate to the marble workbench using a flat washer, a spring washer, and a hexagonal bolt inside the cylinder. The Y-shaped protective cover fixing bracket, side protective cover clamping blocks, and other components are assembled sequentially using bolts and washers of appropriate specifications, eliminating the need for extensive additional machining of auxiliary parts. Furthermore, left-right and up-down clearance adjustments are achieved simply by loosening or tightening the corresponding bolts; the hexagonal bolt inside the cylinder adjusts left-right clearance, and the hexagonal bolt inside the cylinder adjusts up-down clearance. This eliminates the need to disassemble complex structures, significantly simplifying the installation and adjustment process, shortening assembly time, and substantially improving overall work efficiency.

[0018] 2. This utility model features a corresponding adjustment design where the Y-shaped guard fixing bracket controls the left and right clearances, and the side guard clamping block controls the up and down clearances. This design allows for precise control of the left and right clearances of the Y-axis side guard by adjusting the horizontal position of the Y-shaped guard fixing bracket on the Y-shaped guard connecting plate, according to actual working conditions. Furthermore, by changing the vertical height of the side guard clamping block on the Y-shaped guard fixing bracket, the up and down clearances are precisely controlled. This prevents guard offset or jamming due to improper clearances, ensuring the stability of the coordinate measuring machine during operation and meeting the precision requirements of precision measuring equipment for component fit.

[0023] refer to Figure 1 and Figure 2An adjustable mounting structure for a three-axis coordinate measuring machine (CMM) side guard includes a marble worktable 1, a Y-guard connecting plate 2, a flat washer 3, a spring washer 4, a cylindrical hexagonal bolt 5, a Y-guard support plate 6, a flat washer 7, a spring washer 8, a cylindrical hexagonal bolt 9, a cylindrical hexagonal bolt 3 10, a Y-guard fixing bracket 11, a spring pin 12, a side guard clamping block 13, and a Y-axis side guard 14; the Y-guard connecting plate 2 is connected to the cylindrical hexagonal bolt 5 via the flat washer 3 and the spring washer 4. Bolt 15 is fixedly installed on the marble workbench 1; Y-cover fixing bracket 11 is fixedly installed on Y-cover connecting plate 2 by flat washer 27, spring washer 28 and hexagonal bolt 310 inside the cylinder; spring pin 12 is assembled on side cover clamping block 13; side cover clamping block 13 is fixedly installed on Y-cover fixing bracket 11 by flat washer 27, spring washer 28 and hexagonal bolt 29 inside the cylinder; Y-axis side cover 14 is inserted between side cover clamping block 13 and Y-cover fixing bracket 11;

[0024] refer to Figure 1 and Figure 2 The connection structure between the Y-cover fixing bracket 11 and the Y-cover connecting plate 2 allows for adjustment of the left and right clearance of the Y-axis side cover 14. By loosening or tightening the hexagonal bolts 310 inside the cylinder, the horizontal position of the Y-cover fixing bracket 11 on the Y-cover connecting plate 2 is adjusted, thereby driving the Y-axis side cover 14 to move synchronously to adapt to the accuracy requirements of the left and right clearance under different working conditions.

[0025] Furthermore, the connection structure between the side shield clamping block 13 and the Y-shield fixing bracket 11 allows for adjustment of the vertical clearance of the Y-axis side shield 14. By loosening or tightening the hexagonal bolts 29 inside the cylinder, the vertical height of the side shield clamping block 13 on the Y-shield fixing bracket 11 is changed, thereby adjusting the vertical distance between the side shield clamping block 13 and the Y-shield fixing bracket 11, achieving precise control of the vertical clearance of the Y-axis side shield 14.

[0026] For further reference Figure 1 and Figure 2 The connection between the Y-cover connecting plate 2 and the marble workbench 1 adopts an anti-loosening structure consisting of a flat washer 3 and a spring washer 4. The flat washer 3 is attached to the surface of the marble workbench 1, and the spring washer 4 is located between the flat washer 3 and the nut of the hexagonal bolt 5 inside the cylinder. This can effectively prevent the hexagonal bolt 5 inside the cylinder from loosening due to vibration during equipment operation, thus ensuring connection stability.

[0027] Furthermore, the connection between the Y-cover fixing bracket 11 and the Y-cover connecting plate 2, and the connection between the side cover clamping block 13 and the Y-cover fixing bracket 11, both adopt an anti-loosening structure consisting of a flat washer 7 and a spring washer 8. The flat washer 7 fits against the surface of the connected parts, and the spring washer 8 is located between the flat washer 7 and the nut of the corresponding bolt, which can prevent the bolts from loosening during long-term operation of the equipment, and at the same time reduce the wear of the bolts on the surface of the connected parts.

[0028] Furthermore, the spring pin 12 and the side cover clamping block 13 are interference fit, and the axis of the spring pin 12 is parallel to the vertical direction of the side cover clamping block 13. This can position the installation position of the side cover clamping block 13, ensure the assembly accuracy of the side cover clamping block 13 and the Y-cover fixing bracket 11, and prevent the Y-axis side cover 14 from shifting after insertion.

[0029] The overall working principle of this utility model is as follows:

[0030] The marble workbench 1 serves as the basic support, providing a high-precision installation reference surface to ensure overall assembly accuracy. The Y-shaped protective cover connecting plate 2 is fixed to the marble workbench 1 using flat washers 3 and spring washers 4, along with hexagonal bolts 5 inside the cylinder. Flat washers 3 fit snugly against the workbench to prevent damage, while spring washers 4 prevent bolt vibration and loosening, providing a reliable connection carrier for subsequent components. The Y-shaped protective cover support plate 6 further enhances structural rigidity, preventing deformation of components such as the Y-shaped protective cover fixing bracket 11 under stress, and adapts to the weight of the Y-axis side protective cover 14. To meet quantity and operational requirements, the Y-cover fixing bracket 11 is mounted on the Y-cover connecting plate 2 via flat washer 7, spring washer 8, and hexagonal bolt 3 10 inside the cylinder. The Y-axis side cover 14 is inserted between it and the side cover clamping block 13. The horizontal position of the fixing bracket determines the left and right position of the cover. The Y-cover fixing bracket 11 is mounted on the Y-cover connecting plate 2 via flat washer 7, spring washer 8, and hexagonal bolt 3 10 inside the cylinder. The Y-axis side cover 14 is inserted between it and the side cover clamping block 13. The horizontal position of the fixing bracket determines the left and right position of the cover. The position determines the left and right position of the protective cover. The side protective cover clamping block 13 is installed on the Y-protective cover fixing bracket 11 via flat washer 7, spring washer 8, and hexagonal bolt 9 inside the cylinder. The spring pin 12 is interference-fitted to the clamping block, with its axis parallel to the vertical direction of the clamping block, guiding the adjustment direction and preventing deflection. The vertical distance between the clamping block and the fixing bracket determines the upper and lower clearance of the protective cover. The side protective cover clamping block 13 is installed on the Y-protective cover fixing bracket 11 via flat washer 7, spring washer 8, and hexagonal bolt 9 inside the cylinder. The interference fit is applied to the clamping block, with the axis parallel to the vertical direction of the clamping block. This guides the adjustment direction and prevents deflection. The vertical distance between the clamping block and the fixed bracket determines the upper and lower clearance of the cover. The connections between the Y-cover connecting plate 2 and the worktable, the fixed bracket and the connecting plate, and the clamping block and the fixed bracket all adopt anti-loosening structures to prevent bolt vibration and loosening, ensuring stable assembly accuracy. The spring pin 12 restricts the radial rotation of the side cover clamping block 13 to prevent the cover from shifting, further ensuring installation accuracy and meeting the accuracy requirements of the coordinate measuring machine.
