Description

Technical Field

[0001] This utility model relates to the field of industrial measurement technology, and in particular to a combined universal measuring tool auxiliary measuring device. Background Technology

[0002] Micrometers, vernier calipers, and dial indicators are common standard tools used in industrial measurement. Their measurement accuracy is significantly affected by the operator's sense of responsibility, experience, and skill level. To reduce the difficulty of using general-purpose measuring tools, improve measurement accuracy, and ensure consistent results, equipping measuring tools with auxiliary measuring devices is becoming increasingly common. However, most existing auxiliary measuring devices are dedicated to different measuring tools, have relatively limited functions, high manufacturing costs, narrow applicability, are inconvenient to disassemble, carry, and upgrade, and lack adaptability to harsh industrial working environments. Summary of the Invention

[0003] The purpose of this utility model is to provide a combined universal measuring tool auxiliary measuring device to address the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution: The combined universal measuring tool auxiliary measuring device of this utility model includes a support column, with cylindrical clamps coaxially arranged at both ends of the support column; a pair of connecting plates are fitted onto the cylindrical clamps located at the upper end of the support column, the two connecting plates extending outward from their fitting points with the cylindrical clamps and arranged at an angle; a horizontal cross brace is erected between the ends of the two connecting plates furthest from the support column, the middle of the horizontal cross brace being a cylindrical rod, and a translation slider is fitted onto the cylindrical rod. An angle positioning bolt with its inner end fixed to the cylindrical rod is threaded through the upper screw. An upper clamping plate is provided horizontally outward on the side of the sliding slider away from the supporting column. An adjusting screw is threaded vertically through the upper clamping plate. The lower end of the adjusting screw is rotatably connected to a lower clamping plate that is adapted to the upper clamping plate through a rotary bearing fitted on it. At least two column legs are fitted on the cylindrical clamping head located at the lower end of the supporting column. The column legs are horizontally arranged plate-shaped structures, and leveling feet are provided at their ends away from the supporting column.

[0005] Furthermore, the leveling support includes a leveling screw that is vertically screwed onto the column support leg. The upper end of the leveling screw is provided with a grip, and the lower end is connected to an anti-slip rubber block. The height of the anti-slip rubber block on each column support leg can be adjusted by turning the leveling screw, thereby achieving the leveling function and ensuring that the entire device can be placed stably.

[0006] Furthermore, for ease of assembly and disassembly, both ends of the horizontal cross brace should be fixedly connected to the two connecting plates as a whole by bolt assemblies.

[0007] Furthermore, threaded connectors are provided on the ends of the two cylindrical clamps that are away from the support column. Clamping nuts are screwed onto the threaded connectors. The clamping nuts can be used to clamp the connecting plates and column legs on the cylindrical clamps that are clamped on the upper and lower ends of the support column to prevent them from coming loose.

[0008] Furthermore, the support column is coaxially assembled with an outer sleeve and an inner sleeve. A height positioning bolt with its inner end fixed to the inner sleeve is screwed through the upper end of the outer wall of the outer sleeve to realize the height adjustment of the support column.

[0009] Furthermore, corresponding anti-slip rubber pads are provided on the lower surface of the upper clamping plate and the upper surface of the lower clamping plate to increase friction and ensure a more stable clamping of the general measuring tool.

[0010] Furthermore, a lateral screw is vertically screwed through one side of the translation slider, and a side clamp is movably fitted on the lateral screw. By screwing the lateral screw, the side clamp and the translation slider cooperate to clamp the indicator for measurement operation.

[0011] Furthermore, a set of two horizontally rotating connecting rods can be hinged to the top wall of the translation slider, and a magnifying glass can be connected to the outer end of the two connecting rods. A supplementary light is provided on the outer ring of the magnifying glass. The magnifying glass can magnify the scale markings on the general measuring instrument, making it easier for the operator to clearly observe and read the measurement values.

[0012] The advantages of this invention lie in its ability to stably clamp various general-purpose measuring tools through the upper clamping plate, lower clamping plate, and side clamping plate set on the translation slider. Simultaneously, the horizontal movement of the translation slider on the horizontal cross brace or the horizontal rotation of the cross brace around the supporting column as the central axis allows for easy measurement of different general-purpose measuring tools. It enables flexible selection of measurement positions for measuring various parameters of dimensions and form and position errors, facilitating easy measurement work for operators with limited experience or skills. This helps operators reliably use general-purpose measuring tools to obtain accurate and stable measurement results, reducing labor intensity and improving adaptability. Furthermore, the various components of the entire auxiliary measuring device adopt a detachable modular design, facilitating manufacturing, disassembly, storage, and assembly. Different sizes of device parts can also be manufactured according to actual usage requirements to match different measurement objects. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 , 2 As shown, the combined universal measuring tool auxiliary measuring device of this utility model includes a support column 1 and cylindrical clamps 2 coaxially arranged at the upper and lower ends of the support column 1. To achieve height adjustment of the support column 1, the support column 1 can adopt a telescopic sleeve structure consisting of an outer sleeve 1.1 and an inner sleeve 1.2 coaxially fitted together. In this case, one of the two cylindrical clamps 2 is fixed to the lower end face of the outer sleeve 1.1, and the other is fixed to the upper end face of the inner sleeve 1.2. At the same time, a height positioning bolt 3 that can be fixed to the inner sleeve 1.2 should be screwed through the upper end of the outer wall of the outer sleeve 1.1. When the inner sleeve 1.2 and the outer sleeve 1.1 are telescopically adjusted to the correct position, the height positioning bolt 3 can be screwed inward to fix it to the tube wall of the inner sleeve 1.2, thereby fixing the telescopic length of the inner sleeve 1.2 and the outer sleeve 1.1.

[0020] A pair of connecting plates 4 are fitted onto the cylindrical clamp 2 located at the upper end of the support column 1, such as... Figure 3 As shown, the two connecting plates 4 extend outward from their fitting point with the cylindrical clamp 2, arranged at an angle. A horizontal brace 5 is installed between the ends of the two connecting plates 4 furthest from the supporting column 1. The two ends of the horizontal brace 5 can be fixed to the outer ends of the two connecting plates 4 by bolt assemblies, thus forming a triangular frame that is easy to assemble and disassemble. This triangular frame is installed horizontally on the upper end of the supporting column 1. The middle part of the horizontal brace 5 is a cylindrical rod 6, on which a translation slider 7 is fitted. Figure 4As shown, at least one set of translation sliders 7 is provided. Each set of translation sliders 7 is screwed with an angle positioning bolt 8 whose inner end can be fixed to the cylindrical rod 6. This ensures that the translation sliders 7 can be translated laterally and rotated longitudinally on the cylindrical rod 6. After the translation sliders 7 are adjusted to the correct position, the angle positioning bolts 8 can be screwed inward to fix them to the rod wall of the cylindrical rod 6, thereby fixing the position of the translation sliders 7. In addition, an upper clamping plate 9 is horizontally extended outward on the side of the translation slider 7 away from the supporting column 1. An adjusting screw 10 is vertically screwed through the upper clamping plate 9. The lower end of the adjusting screw 10 is rotatably connected to a lower clamping plate 12 that is adapted to the upper clamping plate 9 through a rotary bearing 11 fitted on it. By turning the adjusting screw 10, the lower clamping plate 12 is driven to move upward or downward, thereby cooperating with the upper clamping plate 9 to complete the stable clamping or loosening of the general measuring tool. In order to improve the clamping stability of the upper clamping plate 9 and the lower clamping plate 12, corresponding anti-slip rubber pads 13 can be provided on the lower surface of the upper clamping plate 9 and the upper surface of the lower clamping plate 12. The anti-slip rubber pads 13 increase the friction and ensure a more stable clamping of the general measuring tool.

[0021] At least two column legs 14 are fitted onto the cylindrical clamp 2 located at the lower end of the supporting column 1. The column legs 14 are horizontally arranged plate-like structures, such as... Figure 5 As shown, all column support legs 14 extend outward from their fitting with the cylindrical clip head 2 at an angle, and each column support leg 14 is provided with a leveling foot 15 at the end away from the supporting column 1. The leveling foot 15 includes a leveling screw 15.1 that is vertically screwed through the column support leg 14. The upper end of the leveling screw 15.1 is provided with a grip part 15.2, and the lower end is connected to an anti-slip rubber block 15.3. The height of the anti-slip rubber block 15.3 at the lower end can be adjusted by turning the leveling screw 15.1, thereby realizing the leveling function and ensuring stable placement.

[0022] Furthermore, in order to prevent the connecting plate 4 and the column support leg 14 from slipping off the cylindrical clamp 2, a threaded connector 16 should be provided extending outward from the end of the two cylindrical clamps 2 away from the supporting column 1, and a threaded clamping nut 17 should be fitted on the threaded connector 16. The height of the threaded cavity of the clamping nut 17 should be greater than the height of the threaded connector 16, so that the connecting plate 4 or the column support leg 14 clamped on the cylindrical clamp 2 can be clamped and secured to prevent slippage through the clamping nut 17.

[0023] Furthermore, due to the special structure of the dial indicator, which can only be clamped at the rear lug of the dial indicator or near the rear of the indicator, a lateral screw 19 should be vertically screwed through one side of the translation slider 7, and a side clamp 20 should be movably mounted on the lateral screw 19. This allows the side clamp 20 to move towards the translation slider 7 by screwing the lateral screw 19 inward. The cooperation between the side clamp 20 and the translation slider 7 is then used to clamp the rear lug of the dial indicator or near the rear of the indicator, ensuring that the indicator is in a horizontal position with the dial facing upward. At this time, the pointer tip of the indicator can point horizontally to the left or right, directly measuring the object to be measured.

[0024] Furthermore, a set of two horizontally rotating connecting rods 18 can be hinged to the top wall of the translation slider 7, and a magnifying glass 21 can be connected to the outer end of the two connecting rods 18. This allows the scale markings on the general measuring instrument to be magnified through the magnifying glass 21, so that the operator can clearly observe the measurement values. Of course, a soft-light supplementary lamp 22 can also be set on the lower surface of the outer ring of the magnifying glass 21, and a rechargeable power supply compartment or battery power supply compartment can be set on the two connecting rods 18 connected to the magnifying glass 21 to provide supplementary lighting in the case of insufficient light, so that the operator can accurately read the measurement values ​​on the general measuring instrument.

[0025] When a micrometer is needed to measure the high-precision linear dimensions of an object, the upper clamping plate 9 and the lower clamping plate 12 can be used to secure the insulating plate of the micrometer, so that the micrometer is placed horizontally next to the object. Then the micrometer can be operated to clamp the object with its measuring jaws for high-precision measurement.

[0026] When it is necessary to use a vernier caliper to measure the normal accuracy linear dimension of the object to be measured, the upper clamp 9 and the lower clamp 12 can be used to firmly hold the scale body of the vernier caliper, so that the vernier caliper is placed horizontally next to the object to be measured, and then the vernier caliper can be operated to make its measuring jaws hold the object to be measured for normal accuracy measurement.

[0027] When an auxiliary indicator is needed to measure the straightness error (or parallelism error) or roundness error of an object, the side clamp 20 and the sliding slider 7 can be used to securely hold the dial indicator's rear lug or the back of the dial indicator, ensuring the indicator is in a horizontal position with the dial facing upwards. In this case, the pointer tip of the indicator will be horizontally pointing to the left or right. When measuring the straightness error (or parallelism error) of an object, simply place the object on the left side of the device, then clamp the indicator using the side clamp 20 and the sliding slider 7, ensuring the pointer tip is horizontally pointing to the left, directly facing the object on the left side of the device. Moving the sliding slider 7 along the length of the cylindrical rod 6 will cause the pointer tip of the indicator to move linearly, thus detecting the straightness error (or parallelism error) of the object. When measuring the roundness error of an object, simply place the object on... The indicator is held on the clamping nut 17 at the upper end of the support column 1 (a horizontal support plate that can increase the support area can be installed on the clamping nut 17). Then, the indicator is held by the side clamping plate 20 and the sliding slider 7, and the pointer tip of the indicator is kept horizontally to the right and facing the object to be measured placed on the clamping nut 17. At this time, with the support column 1 as the central axis, the tripod composed of the connecting plate 4 and the horizontal cross brace 5 is rotated, which can drive the indicator to rotate 360° around the outer circumference of the object to be measured, thereby detecting the roundness error of the object to be measured.

[0028] The fixed upper clamping plate 9 and the movable lower clamping plate 12 can stably clamp various general-purpose measuring tools. At the same time, the translation slider 7, which can move and rotate on the cylindrical rod 6 in the middle of the horizontal cross brace 5, can realize the multi-directional movement of the general-purpose measuring tools. This helps operators with limited experience or ability to easily complete measurement work, and helps operators reliably use general-purpose measuring tools to obtain accurate and stable measurement results, reduce labor intensity, and improve adaptability. In addition, all components of the entire auxiliary measuring device adopt a detachable modular design, which is convenient for manufacturing, disassembly, storage and assembly. Different sizes of device parts can also be manufactured according to actual use needs to match different measurement objects.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
