Example 1

Referring to fig. 1 to 3, a first embodiment of the present application provides a connection assembly for fastening and fixing connection between structural members; the connection assembly comprises a fixed part 10, two movable parts 20, a connecting part 30 and other parts which are present according to the need.

In order to describe the structure, connection principle, etc. of the connection assembly in more detail, two target objects that are fixedly connected by the connection assembly are defined as a tuned piece a and a preset carrier B, respectively; the adjusted component A can be a structural component with higher requirement on surface flatness, for example, the adjusted component A is a back plate used for loading optical elements in the optical detection equipment, and correspondingly, the preset carrier B is a mounting platform or a mounting bracket of the optical detection equipment; the member a is generally configured with a mounting through hole disposed therethrough, and the predetermined carrier B is configured with a corresponding connection hole site, and it is understood that the mounting through hole is disposed in coaxial communication with the connection hole site when the member a is mounted on the predetermined carrier B.

Referring to fig. 1 and 3, the fixing member 10 is configured to be fixedly mounted on the adjusted member a, and specifically, the fixing member 10 is disposed through a mounting hole of the adjusted member a and fixedly connected to the adjusted member a, for example, fastened by a screw, fastened, welded, bonded, and the like. The fixing member 10 has a first through hole 10a penetrating in the longitudinal direction, hemispherical spherical clamping grooves 10b are concavely formed in the surfaces of the fixing member 10 at the two ends of the first through hole 10a, and the spherical clamping grooves 10b are coaxially communicated with the first through hole 10 a.

By means of the first through-hole 10a and the spherical clamping grooves 10b at both ends thereof, a structural channel can be formed on the fixing member 10, which allows the connecting member 30 to pass through the fixing member 10, and it is also understood that the fixing member 10 can be sleeved on the connecting member 30 by means of the structural through-hole.

Referring to fig. 1 to 3, the movable member 20 is mainly used as a mating carrier between the connecting member 30 and the fixed member 10, and the movable member 20 has a second through hole 20a and a spherical clamping protrusion 20b with a hemispherical outer contour; wherein, the spherical clamping convex 20b can be adaptively embedded into the spherical clamping groove 10b, so that the movable piece 20 and the fixed piece 10 have the condition of relatively generating ball rotation movement; the second through hole 20a is disposed through the spherical clamping protrusion 20b to allow the connecting member 30 to pass through the movable member 20 (e.g., the spherical clamping protrusion 20 b), which means that the movable member 20 can be sleeved on the connecting member 30 through the second through hole 20 a.

In terms of the structural layout of the connection assembly in the assembled state or the applied state, the two movable pieces 20 are arranged on both sides of the fixed piece 10 (or the piece a to be adjusted) along the length direction of the fixed piece 10; for convenience of distinction and description, the movable member 20 on the side of the regulated member a facing away from the preset carrier B is defined as a first movable member 21, and the movable member 20 on the side of the regulated member a facing toward the preset carrier B is defined as a second movable member 22.

Referring to fig. 1 to 3, the connecting member 30 is mainly used for connecting with a preset carrier B, so as to clamp and fix the adjusted member a to the preset carrier B under the cooperation of the fixed member 10 and the movable member 20; specifically, the whole of the connector 30 is generally a bolt structure, which includes a limiting portion 31 and a connecting rod portion 32 having an external thread structure; the limiting portion 31 is disposed at one end of the connecting rod portion 32, and the first movable member 21, the fixed member 10 and the second movable member 22 are sequentially sleeved on the connecting rod portion 32, so that one end of the connecting rod portion 32 (or one end opposite to the limiting portion 31) penetrating from the second movable member 22 can be in alignment and screwed with a connecting hole of the preset carrier B.

When the connecting component is specifically applied, the fixing piece 10 can be fixed on the adjusted piece A in advance, and then the connecting piece 30 sequentially passes through the first movable piece 21, the fixing piece 10 and the second movable piece 22, so that the combined assembly of the connecting component and the adjusted piece A is realized; then, the connecting piece 30 is aligned and inserted into the connecting hole of the preset carrier B, and the first movable piece 21, the fixed piece 10 (together with the adjusted piece a) and the second movable piece 22 can be pressed towards the preset carrier B by means of the limiting portion 31 by screwing the connecting piece 30, so that the spherical clamping protrusions 20B of the first movable piece 21 and the second movable piece 22 are embedded into the corresponding spherical clamping grooves 10B, and finally the adjusted piece a is clamped and fixed on the preset carrier B.

In this process, if the adjusted component a is limited by its structure or the structure of the preset carrier B interferes with the other component, and a certain angle of inclination occurs in the horizontal direction or the vertical direction, or the adjusting component a drives the fixing component 10 to incline synchronously when the inclination angle of the adjusted component a is adjusted by adjusting the tightness between the adjusting component a and the preset carrier B by means of the connecting component 30, the relative position or posture between the movable component 20 and the fixing component 10 can be adaptively adjusted and changed due to the matching relationship between the spherical clamping groove 10B and the spherical clamping protrusion 20B.

On the one hand, by means of the matching relation between the spherical clamping groove 10b and the spherical clamping protrusion 20b, the regulated piece A can be guaranteed to have a certain degree of inclination freedom, so that the connecting component can adaptively change the posture of the connecting component according to the inclination angle of the regulated piece A, and the deformation of the local part (such as the connecting part of the connecting component) of the regulated piece A caused by excessive stress is effectively avoided, and the surface flatness of the regulated piece A can be stably maintained. On the other hand, by means of the cooperation of the spherical clamping groove 10B and the spherical clamping protrusion 20B, the connection direction, the stress direction and the like between the connecting piece 30 and the preset carrier B are not changed, so that the adjusted piece a can be firmly connected and fixed on the preset carrier B.

In other embodiments, the connecting member 30 may take other forms, for example, the connecting member 30 may be configured in a connection form that can be engaged with the preset carrier B or cannot adjust tightness. In addition, according to actual needs, only one movable member 20 may be configured, for example, one of the first movable member 21 and the second movable member 22 may be omitted.

In one embodiment, the hole wall of the second through hole 20a is provided with an internal thread structure, and the connecting rod portion 32 is disposed through the corresponding spherical clamping protrusion 20B (or the movable member 20) in a threaded fit manner, so that the movable member 20 can be kept relatively fixed with the connecting member 30 when moving relative to the fixed member 10, thereby providing for keeping the stability of the connection between the adjusted member a and the preset carrier B. In other embodiments, the connecting rod portion 32 is provided with an external thread structure only at one end connected with the preset carrier B, and other portions adopt a polish rod structure; in this way, the movable member 20 can be sleeved on the connecting portion 32 in a clearance fit or excessive fit manner, so as to meet different assembly requirements or application requirements.

In one embodiment, referring to fig. 1 to 3, the connecting assembly further includes two buffering members 40, and the two buffering members 40 are sleeved on the connecting member 30 (specifically, the connecting rod portion 32); for convenience of distinction and description, the two buffers 40 are defined as a first buffer 41 and a second buffer 42, respectively; wherein the first buffer member 41 is arranged between the first movable member 21 and the limiting portion 31, and the second buffer member 42 is arranged between the second movable member 22 and the preset carrier B.

When the adjustable member a is clamped and fixed on the preset carrier B by using the connecting member 30, the first buffer member 41 and the second buffer member 42 are respectively clamped between the first movable member 21 and the limiting portion 31 and between the preset carrier B and the second movable member 22 in a pressed and bonded mode, so that the friction force between the associated components can be increased by using the buffer member 40, and the damping effect can be achieved at the same time, so that the adjustable member a can be connected and fixed on the preset carrier B more stably.

In particular embodiments, the cushioning member 40 may be configured with reference to existing cushioning members, such as flat cushioning members made of metal or plastic materials.

In another embodiment, the buffer member 40 and the corresponding movable member 20 can also be integrally formed based on the material difference or actual requirement of the movable member 20, namely: the buffer member 40 and the corresponding spherical clamping protrusion 20b are oppositely arranged along the length direction of the movable member 20 to serve as two ends of the movable member 20 respectively; thereby, the number of components constituting the connection assembly can be reduced. Of course, in some embodiments, one of the first buffer 41 and the second buffer 42 may also be omitted.

In one embodiment, referring to fig. 1 to 3, the fixing member 10 includes a positioning portion 11 and a fixing portion 12; the positioning portion 11 is a cylinder structure with a first through hole 10a and a spherical clamping groove 10b, is sleeved on the connecting piece 30 (specifically, the connecting rod portion 32) and can be penetrated in the mounting through hole of the adjusted piece A; the fixing portion 12 is formed at an edge of one end of the positioning portion 11 adjacent to the first movable member 21, and is used for being fixedly connected with a surface of the adjusted member a opposite to the preset carrier B, so that the positioning portion 11 is fixedly positioned in the mounting through hole, and therefore the fixed assembly of the fixing member 10 and the adjusted member a is achieved.

In the embodiment, referring to fig. 3, a third through hole 10c may be provided in the fixing portion 12, and the fixing portion 12 and the workpiece a may be fastened and fixed by engaging a fastener 50 such as a screw with the third through hole 10 c. Of course, the fixing portion 12 and the adjusted member a may be fixedly connected by fastening, bonding, welding, etc., which will not be described herein.

Example two

Referring to fig. 4 and 5 in conjunction with fig. 1 to 3, a second embodiment of the present application provides an adjusting device that can be used in an optical detection apparatus to perform positioning assembly and adjustment of a spatial position of an optical element; the assembly device comprises a positioning backboard 100, a connecting assembly 200 and other components which exist according to the needs; the connection assembly 200 is the connection assembly provided in the first embodiment.

Referring to fig. 4 and 5, the positioning back plate 100 is mainly used as a carrier for loading optical elements or components such as a cylindrical lens, a polarizer, a filter, a beam splitter, a lens group, a camera, etc., and the optical elements can be positioned at a preset position along a preset optical path by means of cooperation of the positioning back plate 100 and a mounting platform 300 (or a mounting bracket) of the optical detection device. The positioning back plate 100 has a plurality of mounting through holes 100a disposed therethrough, and each mounting through hole 100a is uniformly and correspondingly provided with a connecting component 200, so that the mounting through holes 100a are used as structural matching parts of the connecting component 200 and the positioning back plate 100.

Specifically, the fixing members 10 are disposed through the corresponding mounting through holes 100a and are integrally fixed to the positioning backplate 200, and the connecting members 30 may be disposed through the first buffer member 41, the first movable member 21, the fixing members 10, the second movable member 22, and the second buffer member 42 in this order. In particular, the plurality of mounting through holes 100a may be arranged at intervals on the positioning backplate 100 in a multi-point distribution (e.g., three points, four points, six points, etc.), so that the positioning backplate 200 can be ensured to be stressed uniformly under the cooperation of the plurality of connection assemblies 200.

It is understood that, with respect to the connection assembly 200, the positioning backplate 100 corresponds to the adjusted member a, and the mounting platform 300 corresponds to the preset carrier B.

In application, the connecting piece 30 can be screwed to correspondingly screw the connecting piece 30 into the connecting hole site 300a of the mounting platform 300, so that the positioning backboard 100 is clamped and fixed on the mounting platform 300; in this process, the connection assembly 100 can adaptively change the structural characteristics of the self-posture according to the inclination angle of the positioning backboard 100, so that the screwing amount of each connection piece 30 can be stably fixed without repeated adjustment or precise control, and the surface flatness of the positioning backboard 100 can be stably maintained under the condition that the surface of the positioning backboard 100 meets the requirement of perpendicularity or levelness, thereby realizing precise assembly of the positioning backboard 100 and creating a favorable condition for precise positioning and assembly of subsequent optical elements.

Based on the application environment of the adjusting device, the application also provides an adjusting method, so that the assembly of the positioning backboard 100 and the mounting platform 300 can be completed rapidly and accurately, and conditions are created for the subsequent positioning assembly of the optical element; referring to fig. 6 in combination with fig. 1 to 5, the assembling method includes a connecting step 1000, a measuring step 2000 and an assembling step 3000.

A connecting step 1000, respectively arranging at least one connecting component 200 at two ends of the positioning backboard 100 in the first direction, and superposing and connecting the positioning backboard 100 on the mounting platform 300 along the second direction by using the connecting piece 30 of the connecting component 200; wherein the first direction is perpendicular to the second direction.

For example, two connection assemblies 200 may be disposed at the upper end and the lower end of the positioning backplate 100, respectively, and the two connection assemblies 200 disposed at the same end of the positioning backplate 100 are arranged at intervals along the left-right direction, so that the positioning backplate 100 is provided with four connection assemblies 200 in a four-point distribution manner; the four connection assemblies 200 can finally fix the positioning backplate 100 to the mounting platform 300 in a stacked manner along the front-rear direction, and ensure the balance of the overall stress of the positioning backplate 100. It is understood that the first direction is the up-down direction and the second direction is the front-back direction.

A measurement step 2000 of obtaining first perpendicularity information between a first end surface of the positioning backboard 100 and the mounting platform 300 and second perpendicularity information between a second end surface of the positioning backboard 100 and the mounting platform 300; the first end surface and the second end surface are two end surfaces of the positioning backboard 100, which are oppositely arranged in the first direction.

For example, the first end surface may be understood as an upper end surface of the positioning back plate 100, and the second end surface may be understood as a lower end surface of the positioning back plate 100; in theory, when the positioning backplate 100 is fixed to the mounting platform 300, if the positioning backplate 100 meets the requirement of perpendicularity or levelness, the first end surface and the second end surface should be distributed perpendicularly to the mounting platform 300. Therefore, by acquiring the first perpendicularity information and the second perpendicularity information, it can be determined whether the first end face and the second end face have inclination angles with respect to the mounting platform 300, respectively, and further it can be determined whether the entire positioning backboard 100 meets the requirement of perpendicularity or levelness.

The first perpendicularity information and the second perpendicularity information include parameters such as an inclination angle of the corresponding end surface with respect to the mounting platform 300. In specific implementation, the first perpendicularity information and the second perpendicularity information can be acquired by means of a measuring instrument such as a collimator.

A step 3000 of adjusting the surface of the positioning backboard 100 to be inclined with respect to the mounting platform 300 according to the first verticality information and the second verticality information; if so, screwing the connecting piece 30 to enable the corresponding first movable piece 21 and the second movable piece 22 to adaptively move relative to the fixed piece 10 (together with the positioning backboard 100), and then continuing to execute the measuring step 2000; if not, the optical element is mounted on the positioning back plate 100, and the final assembly of the positioning back plate 100 and the optical element is completed.

In specific implementation, the judgment on whether the positioning backboard 100 is inclined can be realized by judging whether the first perpendicularity information and the second perpendicularity information are within a preset perpendicularity range; specifically, if the first perpendicularity information and the second perpendicularity information are both within the preset perpendicularity range, it may be determined that the surface of the positioning backplate 100 is not inclined with respect to the mounting platform 300, that is: the surface verticality or levelness of the positioning backboard 100 meets the requirement, so that subsequent optical element assembly can be performed; if at least one of the first verticality information and the second verticality information is not within the preset verticality range, it indicates that the surface of the positioning backboard 100 is inclined with respect to the mounting platform 300, that is, the surface verticality or levelness of the positioning backboard 100 does not meet the requirement, and at this time, the inclination angle of the positioning backboard 100 needs to be adjusted by means of the connection assembly 200.

Of course, the difference between the first verticality information and the second verticality information may also be calculated, and the final determination of the surface verticality or levelness of the positioning backboard 100 may be achieved by determining whether the difference is within a preset difference range; specifically, if the difference between the first perpendicularity information and the second perpendicularity information is not within the preset difference range, it indicates that the positioning backboard 100 is inclined, and the requirement of levelness or perpendicularity cannot be met; therefore, the inclination of the positioning backplate 100 needs to be adjusted by means of the connection assembly 200; on the contrary, if the difference between the first verticality information and the second verticality information is within the preset difference range, it indicates that the inclination of the positioning backboard 100 meets the requirement of levelness or verticality, and the optical element can be assembled on the positioning backboard 100.

Referring to fig. 7 in combination with fig. 4 and fig. 5, the following test data table can be obtained by taking the example that the positioning backboard 100 is stacked on the mounting platform 300 along the front-back direction, two connecting assemblies 200 are respectively disposed at two ends of the positioning backboard 100 along the up-down direction, the upper end of the positioning backboard 100 is used for mounting a camera, and the lower end of the positioning backboard 100 is used for mounting an objective lens, and the following test data table is tested.

It should be noted that, i and ii in the table represent the connection members 30 of the two connection assemblies 200 located at the upper end of the positioning backplate 100, and iii and iv represent the connection members 30 of the two connection assemblies 200 located at the lower end of the positioning backplate 100; the objective lens end surface represents the lower end surface (or one of the first end surface and the second end surface) of the positioning back plate 100, the camera end surface represents the upper end surface (or the other of the first end surface and the second end surface) of the positioning back plate 100, Y1, Y2, and Y3 refer to three identification bits or detection bits arranged side by side along the width direction (which can be understood as a third direction, which is mutually perpendicular to the first direction and the second direction) of the positioning back plate 100, and X is the both end surfaces of the positioning back plate 100 in the width direction thereof.

As can be seen from the above table, when the connectors 30 of No. i and No. ii are simultaneously tightened, Y1, Y2 and Y3 of the objective lens end face are positively correlated and increased, Y1, Y2 and Y3 of the camera end face are positively correlated and increased, and the end face X is hardly changed; accordingly, it is described that when the upper end portion of the positioning backplate 100 is inclined, the lower end portion of the positioning backplate 100 is also inclined adaptively. When the III and IV connectors 30 are tightened, Y1, Y2 and Y3 of the end faces of the objective lens are reduced in positive correlation, Y1, Y2 and Y3 of the end faces of the camera are also reduced in positive correlation, and the end face of the X has almost no change; thus, it is described that when the inclination of the lower portion of the positioning backplate 100 is changed, the upper end portion of the positioning backplate 100 is also adaptively inclined.

In summary, by means of the structural fit between the spherical clamping groove 10b and the spherical clamping protrusion 20b in the connection assembly 200, the positioning backboard 100 will not deform when the connection assembly 200 is tightened or loosened, and the surface flatness of the positioning backboard 100 can be stably maintained. Based on this, the adjusting device or the connecting assembly 200 provided in the present embodiment may be applied to a field or an occasion with a high requirement on the installation precision or the flatness precision, for example, a precision optical detection system or a device.

Example III

Referring to fig. 8 in combination with fig. 1 to 7, a third embodiment of the present application provides a mounting device, which is different from the mounting device provided in the second embodiment in that: the fixing member 10 is omitted from the connection assembly 200, and the positioning back plate 100 is provided with a spherical clamping groove 10b matched with the spherical clamping protrusion 20 b.

Specifically, the positioning backplate 100 is provided with a plurality of first through holes 10a through which the corresponding connectors 30 are allowed to pass, and the spherical clamping grooves 10b are concavely formed on the surfaces of the positioning backplate 100 at the two ends of the first through holes 10a, that is, the first through holes 10a and the spherical clamping grooves 10b together form the mounting through holes 100a of the positioning backplate 100.

When the positioning backboard 100 is applied, after the connecting piece 30 sequentially passes through the corresponding first buffer piece 41, the first movable piece 21, the positioning backboard 100, the second movable piece 22 and the second buffer piece 42, the positioning backboard 100 can be clamped and fixed on the mounting platform 300, so that the structural complexity of the adjusting device can be reduced, the convenience of assembling the adjusting device and the mounting platform 300 can be improved, and the surface flatness of the positioning backboard 100 can be stably maintained.

As for the specific adjusting method of the adjusting device and the principle of the technical effect, the foregoing is described, and will not be described herein.

The foregoing description of the utility model has been presented for purposes of illustration and description, and is not intended to be limiting.
