Description

The useful model "Tari caliper" belongs to the control and measuring tools for particularly precise external and internal measurements.

Traditional calipers, in contrast to micrometers and indicators, do not have devices of tare measurement effort |1, 2), which reduce the negative impact of the operator on the measurement process. The micrometer and indicator gauge provide only one direction of measurement (external only or internal only).

Vernier calipers are the only ones among other types of gauges (micrometric and indicator) that provide 4 measurements (external, internal, depth and ledge) (1, 21:

External measurements are performed when the measuring jaws approach;

Internal measurements, depths and ledges are performed when measuring jaws are diluted;

The international standard (2) provides for increased errors of external measurements, depth measurements and ledges (compared to external measurements).

The overall potential of calipers exceeds the economic and metrological capabilities of micrometric and indicator gauges, with the exception of the tared device.

The purpose of the useful model "Tariable Vernier Caliper" is to improve the error of the vernier caliper by 2.5...5 times during internal measurements, when measuring depths and ledges.

The patent analogue of the useful model "Vertical caliper" is the 130-year-old American patent О5 Мо 425208 |ЗИ, in which a measuring rod with a spring-lever device is mounted on one of the two movable measuring jaws to determine the moment of contact, further movement of the measuring rod with possible calculation tared effort. Despite the absence of a vernier and a simplified design of two moving frames, the patent-analogue of the IZ) is promising for the possibility of controlling the tare force.

The disadvantage of the analogue patent |Z| there is an impossibility of internal measurements with appropriate control of the tare force.

The patent analogue of the utility model "Tared caliper" is the 103-year-old American patent SHO5 Mo 1288034 |4Y), in which a measuring rod with a spring-lever device is mounted on the adjustable jaw to determine the moment of contact, further movement of the measuring rod with the possible calculation of the tare force.

Analog patent |4| in terms of metrological capabilities, it is similar to the analogue patent |C), therefore it has identical disadvantages.

A patent analogue of the useful model "Vertical vernier caliper" is an interesting 102-year-old American patent 5 Mo 1355724 IB, in which a measuring rod with a spring-lever mechanism for determining the moment of contact and an indicator of the movement of the rod with an indication on an incremental scale is mounted on a moving sponge. mark for the tare effort. Analog patent |5| also has linear and circular scales and a set of interchangeable tips for external and internal measurements. Analog patent |I5| summarizes early tared caliper patents.

A very complex rod-micrometric design of the patent analog I|5| significantly limited its technical and economic feasibility, there is no information about its production and use.

A patent analogue of the utility model "Tariable vernier caliper" is the well-known 0-year American patent 5 Mo 3113384 |6) with placement of the tare device in a movable frame in the form of a rod with two symmetrical springs, which are used alternately for external and internal measurements. The rod is connected to the threaded mechanism of precise feed.

The compression of both springs is determined only qualitatively (without quantitative values), by the position of the transverse screw in the longitudinal hole of the movable frame of the caliper.

The disadvantage of the analogue patent (b) is the lack of means of quantitative control of the tare forces for external and internal measurements.

The patent-analog of the utility model "Tara vernier caliper" is an American patent

OB Mo 3060586, in which the tare force (6...10N) for external measurements is provided by a micrometric head with an appropriate measurement range (25 or 50 mm).

The disadvantage of the patent analogue is the limited range of measurements (25 mm or 50 mm) and the impossibility of controlling the tare force during internal measurements.

A patent analogue of the useful model "Tared caliper" is the well-known American patent О5 Mo 4188727 ИВ) of specialists of the Japanese firm "Mishowo", in which a rather complex spring-lever device of tare force (only for external measurements) is placed at the beginning of the measuring rod.

The specified patent analogue |В| successfully implemented in a serial digital calibrated caliper model 573-191-30 of the Japanese company "Mishowo" (measurement range - 180 mm, 60 error - 0.050 mm, calibrated force - 1 N, price - about 1000 dollars) (91.

The disadvantage of the patent-analog |8) is the lack of a calibrated force for internal measurements and an extremely high price.

The patent-analog of the utility model "Tara vernier caliper" is an American patent

OB Mo 8898923 10) from specialists of the Japanese company "Mishowo", in which the moving frame contains an electromechanical tare device with a rod and two elastic elements (symmetrical springs on a single rod) with a displacement sensor (using a measuring device of a caliper) to control forces at external and internal measurements under the condition of pressing the roller mechanism of the precise feed. Taking into account the stiffness of the springs 0.25 N/mm and the controlled movement of the rod 2...4 mm, the pressing force is 3...5 N (101.

The disadvantage of the analog patent (10) is the too high complexity and cost of the proposed tare device, which limited its serial production and use until now (for more than 8 years after its patenting) |(91I.

The patent-analog of the utility model "Tara vernier caliper" is an American patent

OB Me 9212883 | 11) specialists of the Japanese company "Miishiouo", in which an electromechanical tare device with a spring element and a pressure force indicator with tactile and sound indication is placed as part of the moving frame with a tactile and sound indication when the limit forces are reached during external and internal measurements (with pressure of the precise movement roller). With a stiffness of the elastic element of 0.25...6 N/mm with a controlled movement of 0.5...5 mm, the controlled pressing force reaches 0.1...10 N 111.

The disadvantage of the analogue patent |(11|) is the too high complexity and cost of the tare device, which did not allow it to be serially produced and used until now (for 6 years after patenting).

The patent-analog of the utility model "Tara vernier caliper" is an American patent

OB Me 9267779 (12) specialists of the Japanese company "Miishiuo", in which an electromechanical calibrated device is placed as part of the moving frame, in which a double torsion with an indicator of bilateral displacements in the range of 0.5...5 mm and a controlled force of bilateral pressing 0.1...10 N.

The disadvantages of the analog patent (12) are identical to the disadvantages of the close analog patent (111.

With the patent-analogue of the utility model "Tariable vernier caliper" there is an American patent 5 Mo 9612099 (131 specialists of the Japanese company "Mishowo", in which the tare device for external and internal measurements is made purely mechanical and is placed directly in the roller of the precision feed mechanism, outside the moving frame The roller is made in one piece with a friction mechanism designed to provide a bidirectional force of 0.5...10 N 1131..

The disadvantage of the analogue patent (13) is the great complexity or even the impossibility of its mass production:

The mechanism of the tare device consists of a large number (more than 10 pcs.) of high-cost precision miniature parts;

The mechanism of the tare device must be placed in the small dimensions of the available rollers of the precision feed mechanism (outer diameter of the rolling surface of the roller - 11.5 mm, thickness of the roller - 7...7.5 mm, internal basic diameter of the roller - 3 mm);

The miniaturization of the calibrated mechanism makes the mechanical rigidity of the structure impossible, complicates dust and moisture protection, makes it impossible to function as a whole (for example, with the available dimensions of the roller of the precision feed mechanism, the length of the miniature spring of the calibrated device of the patent analogue (13) must be less than 2.2 mm, which is not enough for provision of declared effort 10N);

The unsustainability of the analogue patent (13) is confirmed by the lack of its implementation for more than 5 years after its patenting |91|.

B Mo 9631912 (14) of specialists of the Japanese firm "Mishowo", in which a bidirectional calibrated device in the form of a symmetrical ratchet mechanism with two flat springs is installed on the moving frame to ensure calibrated pressing forces during external and internal measurements. In the analog patent (14), the authors do not indicate available tare forces.

The disadvantages of the analog patent (14|) are related to the lack of objective means of control (indicator, effort scale), which complicates its use (for years after patenting, the analog patent (|14) is still not used).

The patent-analog of the utility model "Tara vernier caliper" is an American patent

OB Mo 9417094 |15| specialists of the Japanese company Miishiouo, in which the moving frame contains an electromechanical tare device with a double elastic element (two symmetrical cylindrical springs on a single rod) and a patented displacement sensor (symmetrical inductive system), with a precision feed mechanism attached to the roller.

Patent analog I15)| in terms of kinematics, it is identical to the analogue patent (10| with similar technical and economic disadvantages.

In 2013...2015, researchers of the Japanese company "Mishowo" researched, developed and patented various tare devices for calipers most actively (compared to other manufacturers of calipers), while none of them were implemented in serial samples.

The patent analogue of the utility model "Tared vernier caliper" is the well-known Ukrainian patent Sha Mo 104879 |16), which proposes a tare device in the form of a button-rod that presses on a cylindrical spiral spring in a hollow body to ensure the tare force during external measurements. The tactile sensitivity of the user's finger (when the tactile moving surface of the movable rod and the tactile surface of the stationary end of the body of the calibrated device coincide at the same level) informs about the achievement of the required tare force (|16).

According to the analogue patent (16), it is advisable to install the tare device as follows:

In the threaded hole, which usually connects the threaded mechanism of the exact feed in traditional serial calipers with ranges over 500 mm;

Attach to the moving frame in another way (embedded or otherwise). Due to the rigid design and easy replacement of springs with different stiffness, it became possible to provide the widest range of rated forces (0.5...3 N, 2...12 N, 10...30 N and 25...60 N).

Due to its simplicity and efficiency, the patent-analog (16) is widely used by the enterprise "MICROTECH" (171: 3 of 2016 - in serial medium and large digital calipers of the SHTC type with ranges from 0...500 mm to 0...3000 mm;

Since 2016 - in computer calipers of the "Taryei" type (with built-in minicomputers) in the measurement ranges of 0...500 mm and 0...1000 mm;

Since 2018 - in computer calipers of the "IpiePyidepi" type (with built-in microcomputers) in the measurement ranges of 0...150 mm, 0...200 mm, 0...300 mm.

The disadvantage of the analogue patent (16|) is the impossibility of ensuring the tare forces during internal measurements, measurements of depths and ledges.

Analogous patents of the utility model "Tari caliper" are the American patent

OB Mo 10429165 (18) and the primary Ukrainian patent Sha Mo 100613 (191) from specialists of the company "MICROTECH" (Ukraine), in which a tare device is placed between the moving frame and the precise feed mechanism in the body with an unfastened elastic element on which the rod presses , combined with a precision feed mechanism (roller or screw feed).

Thanks to the strokes on the movable rod and the presence of a mark in the window opening (in the body of the tare device), it is quite simple, fast and effective to determine the tare force during external measurements.

Serial production of tare calipers according to the specified analogue patents 18, 19| coincided with their patenting due to the technological design of the tare device (only 4 fairly simple parts) and a successful combination with micron models of calipers (1 µm and 5 µm resolution), which in general provided the smallest errors in the world for modern calipers (5 µm and 10 µm in range 0...150mm (171).

The disadvantage of analog patents (18, 19|) is the impossibility of internal measurements to ensure the tare force.

The vernier caliper is tared with a rod 1 together with a measuring scale 2, with a fixed external sponge 3, with a fixed internal sponge 4, with a movable frame 5 together with a measuring device 6, with a movable external sponge 7, with a movable internal sponge 8, with a depth gauge 9, with accurate feed mechanism 10, with a tare device 11 as part of a body 12 with a window 13 together with a label 14, an elastic element 15, a rod 16 together with a scale 17, and it differs from the known calibrated vernier caliper in that both ends of the elastic element 14 have fasteners 18 to the body 12 and to the rod 15, an additional scale 19 is applied to the rod 15.

The essence of the useful model "Tariable Vernier Caliper" consists in the bidirectional use of the elastic element 15, see Fig. 1 and Fig. 2.

Rod 1, measuring scale 2, fixed outer sponge 3, fixed inner sponge 4, moving frame 5, counting device b, moving outer sponge 7, moving inner sponge 8, depth gauge 9, precision feed mechanism 10 are common and traditional for modern analog, digital and computer calipers (171.

The tare device 11 as part of the body 12 with a window 13 with a label 14 and an elastic element 15 is practically similar to the corresponding constituent parts of known analog patents (18, 19).

The presence of two mounts 18 and an additional scale 19 as part of the tare device 11 provide additional opportunities for controlling the measuring force during external and internal measurements:

According to Fig. 2a - by compressing the elastic element 15 during external measurements and stretching the elastic element 15 during internal measurements;

According to Fig. 26 - by stretching the elastic element 15 during internal measurements and compressing the elastic element 15 during external measurements.

The housing 1 can be attached to the moving frame 5 as follows:

In parallel, along the lower clearing of the moving frame 5 in the case of using a roller from the precision feed mechanism 10 (similar to Ukrainian small tared digital calipers with ranges of 0...150 mm, 0...200 mm and 0...300 mm (171 );

In line with the moving frame 5, with a threaded attachment to the threaded hole of the moving frame 5 (similar to Ukrainian medium and large digital calipers with ranges from 0...500 mm and more (171). Window 13 is made in the form of a transparent glass or plastic insert, fixed in the opening of the housing 1, while on the transparent insert there is an engraved or otherwise applied marking in the form of a counter mark 14 for determining the tare forces at the corresponding movement of the rod 16.

The rod 16, in addition to the scale 17 (for controlling the forces during external measurements according to analog patents |18, 19!) also has an additional scale 19 (for controlling the forces during internal measurements) with corresponding markings of the reading directions.

The elastic element 15 can be the following (similar to the analog patents (18, 19) or others):

Metallic or non-metallic;

In the form of a cylindrical, conical spiral, rod, flat spring or torsion spring;

With the ability to function on pressing (for external measurements) and on stretching (for internal measurements);

For calibrated calipers, the ratio of calibrated forces during external and internal measurements is equal to External / Internal -0.1...1 (taking into account the materials of the parts,

From the measuring planes of the corresponding jaws, stiffness of special jaws).

The body 12 and the rod 16 have corresponding fasteners 18 for holding the ends of the elastic element 15 when it is pressed or stretched. The fastening 18 of the elastic element 15 on the rod 16 can be in the form of a hook, groove, hole, protrusion or others, see Fig. 2.

The useful model "Tariable vernier caliper" is used as follows: 1) include the counter 6 (if available and necessary to use a digital or computer counter); 2) reset the initial position of the measuring device 6 by bringing the fixed outer jaw З and the movable outer jaw 7 to the required tare force during external measurements, or reset the initial position of the measuring device 5 by spreading the fixed inner jaw 4 and the movable inner jaw 8 until the required tare force is reached when internal measurements, measurements of depths and ledges; 3) carry out appropriate measurements (external or internal and other) with appropriate tared efforts; 4) repeat the transitions of paragraphs 2 and З when changing the direction of measurements; 5) turn off the counter b (if there is a digital or computer counter) automatically or in case of non-use for 20...60 minutes; 6) repeat transitions 2...5 in the case of new series of measurements.
