Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, and in particular relates to clamping structures and optical module adjustment fixtures. Background Technology

[0002] Optical modules are an important component of laser sensors. An optical module typically includes an optical module bracket and emitting and receiving elements mounted on the bracket. During production, the components of the optical module need to be tested and assembled. Clamping fixtures are often used to hold and limit the optical module bracket before testing and assembly.

[0003] However, the existing clamping mechanisms have poor versatility. One type of tooling fixture can only clamp one type of optical module bracket, which means that different types of optical module brackets often require different types of clamping tooling for adaptation, resulting in low applicability. Utility Model Content

[0004] The purpose of this application is to provide a clamping structure and an optical module adjustment fixture, aiming to solve the problem of how to improve the applicability of the clamping structure.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0006] In a first aspect, a clamping structure is provided, including a base plate, a fixing seat fixed on the base plate, a pressure block slidably disposed on the base plate along a first direction, an elastic connector disposed between the fixing seat and the pressure block, and a stop wall disposed on the base plate. The base plate is provided with a limiting groove for placing a workpiece to be clamped, the limiting groove being used to limit the workpiece to be clamped. The pressure block is disposed between the fixing seat and the workpiece to be clamped. One end of the elastic connector is fixed to the fixing seat, and the other end of the elastic connector is elastically connected to the pressure block so that the pressure block elastically abuts against the workpiece to be clamped. The stop wall is disposed on the side of the workpiece to be clamped away from the pressure block, so as to clamp the workpiece to be clamped together with the pressure block along the first direction.

[0007] In some embodiments, the fixing base has a fixing hole on the side facing the clamping member, and the end of the elastic connector away from the pressure block passes through the fixing hole and is fixed to the fixing hole.

[0008] In some embodiments, the resilient connector is a spring pin.

[0009] In some embodiments, the top surface of the base plate is further provided with a placement groove, the fixing seat and the pressure block are disposed in the placement groove, the placement groove is connected to the limiting groove, and the height of the bottom wall of the placement groove is less than the height of the bottom wall of the limiting groove.

[0010] In some embodiments, the base plate further includes a baffle wall connecting the bottom wall of the placement groove and the bottom wall of the limiting groove. The baffle wall faces the surface of the pressing block and is perpendicular to the moving direction of the pressing block. The baffle wall is used to abut against the pressing block to limit the moving stroke of the baffle block.

[0011] In some embodiments, the fixing seat is detachably connected to the base plate, and the position of the fixing seat is adjustable along the direction from the pressure block toward the clamped part.

[0012] In some embodiments, the shape of the limiting groove is adapted to the shape of the member to be clamped.

[0013] In some embodiments, the top surface of the fixing base is provided with a connecting hole, and the clamping structure further includes a fastener, which is movably inserted through the connecting hole and is used to abut against the side wall of the elastic connector to fix the elastic connector.

[0014] In some embodiments, two elastic connectors are provided, each connected to one end of the pressure block, and the two elastic connectors are symmetrical to each other.

[0015] Secondly, an optical module adjustment fixture is provided, the optical module adjustment fixture including the above-mentioned clamping structure.

[0016] The clamping structure provided in this application has a limiting groove that can limit the clamped part. By placing a pressure block between the fixed base and the clamped part, the pressure block can extend towards the limiting groove or retract away from the limiting groove, so that for clamped parts of different sizes, the end of the pressure block facing the clamped part can always be tightly attached to and abut against the clamped part, and together with the stop wall, clamp the clamped part. This allows for adaptive adjustments according to different models and specifications of clamped parts, solving the technical problem of low applicability of existing clamping fixtures, improving versatility and expanding the applicability of the clamping structure.

[0041] Please see Figures 1 to 3This application provides a clamping structure 100, including a base plate 10, a fixing seat 20 fixed on the base plate 10, a pressure block 30 slidably disposed on the base plate 10 along a first direction, an elastic connector 40 disposed between the fixing seat 20 and the pressure block 30, and a stop wall 15 disposed on the base plate 10. The base plate 10 is provided with a limiting groove 11 for placing a clamping part 200, and the limiting groove 11 is used to limit the clamping part 200. The pressure block 30 is disposed between the fixing seat 20 and the clamping part 200. One end of the elastic connector 40 is fixed to the fixing seat 20, and the other end of the elastic connector 40 is elastically connected to the pressure block 30 so that the pressure block 30 elastically abuts against the clamping part 200. The stop wall 15 is disposed on the side of the clamping part 200 away from the pressure block 30 so as to clamp the clamping part 200 together with the pressure block 30 along the first direction X.

[0042] It should be noted that the clamping component 200 in this application can be an optical module bracket, which can be used in laser sensors. The optical module bracket can mount transmitting elements, receiving elements, or other optical elements, such as mirrors and lenses. By clamping the optical module bracket, it is convenient to test and assemble the components on it. Of course, in other possible embodiments, the clamping component 200 can also be other components that need to be positioned. This application does not limit the specific structure of the clamping component 200.

[0043] Understandably, the pressure block 30 can contact one side of the part to be clamped 200, while the stop wall 15 contacts the side of the part to be clamped 200 away from the pressure block 30, and the inner wall of the limiting groove 11 abuts against the two opposite sides of the part to be clamped 200, thereby working together to clamp the various sides of the part to be clamped 200, improving the clamping effect of the part to be clamped 200, and making the fixation of the part to be clamped 200 more stable. In this embodiment, the number of stop walls 15 can be set to two, with the two stop walls 15 respectively connected to the two opposite inner walls of the limiting groove 11, and the extension direction of the two stop walls 15 being perpendicular to the first direction X.

[0044] In actual use, the pressure block 30 is manually pulled towards the fixed base 20, and then the workpiece 200 to be clamped is placed horizontally on the base plate 10, so that the workpiece 200 to be clamped is accommodated in the limiting groove 11, and the inner wall of the limiting groove 11 abuts against the side of the workpiece 200 to be clamped. Since the pressure block 30 is telescopically connected to the fixed base 20, for workpieces 200 with smaller lateral dimensions, the pressure block 30 can extend towards the limiting groove 11, so that the pressure block 30 can be tightly attached to the workpiece 200 to be clamped; for workpieces 200 with larger lateral dimensions, the pressure block 30 can retract away from the limiting groove 11, so that the pressure block 30 can still be tightly attached to the workpiece to be clamped. That is, the pressure block 30 can be adaptively adjusted according to different models and specifications of workpieces 200 to be clamped, and can be used to clamp and position workpieces 200 of different models and specifications. This solves the technical problem of low applicability of existing clamping fixtures and has good versatility.

[0045] The clamping structure 100 provided in this application has a limiting groove 11 that can limit the clamping part 200. By setting the pressure block 30 between the fixed base 20 and the clamping part 200, the pressure block 30 can extend towards the limiting groove 11 or retract away from the limiting groove 11, so that for clamping parts 200 of different sizes, the end of the pressure block 30 facing the clamping part 200 can always be tightly attached to and abut against the clamping part 200. This allows for adaptive adjustments according to different models and specifications of clamping parts 200, solving the technical problem of low applicability of existing clamping fixtures, improving versatility and expanding the applicability of the clamping structure 100.

[0046] In some embodiments, the fixing base 20 has a fixing hole 23 on the side facing the clamped part 200. The end of the elastic connector 40 facing away from the pressure block 30 passes through the fixing hole 23 and is fixed to the fixing hole 23, thereby making the elastic connector 40 firmly fixed and preventing it from detaching when the pressure block 30 acts on the clamped part 200. The elastic connector 40 has a simple structure, which not only facilitates the opening of the pressure block 30 to place the clamped part 200, but also makes it suitable for clamping and positioning clamped parts 200 of different models and specifications.

[0047] Specifically, the elastic connector 40 is a spring-loaded pin. The spring-loaded pin may include a needle tube, a needle shaft, and a spring. The needle tube has an internal cavity, and the needle shaft is disposed in the cavity with one end extending out of the needle tube. The needle shaft can move axially along the needle tube. One end of the spring abuts against the head of the needle shaft, and the other end abuts against the bottom wall of the needle tube. The end of the needle shaft is connected to the pressure block 30, thereby making the pressure block 30 retractable.

[0048] Furthermore, a guide structure can be provided inside the needle tube. The main body of the needle shaft and the first end are guided and matched with the guide structure inside the needle tube. The guide structure can guide the needle shaft when it moves along the axial direction of the needle tube, reducing the possibility of the needle shaft deviating, thereby reducing the possibility of the pressure block 30 deviating and ensuring the straightness of the movement of the pressure block 30.

[0049] In some embodiments, two elastic connectors 40 are provided, which are respectively connected to the two ends of the pressure block 30. The extension directions of the two elastic connectors 40 are parallel to each other, and the two elastic connectors 40 are symmetrical to each other. Therefore, the force applied by the elastic connectors 40 to the pressure block 30 can be more balanced, so that the pressure block 30 will not shift to one side during the movement, thus ensuring the straightness of the movement of the pressure block 30.

[0050] Of course, in other possible implementations, the number of elastic connectors 40 may be three, four, five, six or more, and this application does not limit the number of elastic connectors 40.

[0051] Furthermore, the position of the elastic connector 40 connected to the pressure block 30 can be adjusted according to actual needs. For example, when the number of elastic connectors 40 is set to three, the three connection points formed by the three elastic connectors 40 and the pressure block 30 can form an equilateral triangle by connecting the ends of the three elastic connectors 40, thereby making the force exerted by the elastic connectors 40 on the pressure block 30 more balanced.

[0052] In this embodiment, the shape of the limiting groove 11 is adapted to the shape of the clamping part 200. It is understood that since the clamping part 200 may be an irregularly shaped part, the shape of the limiting groove 11 can also be set to an irregular shape accordingly. Furthermore, the periphery of the clamping part 200 may have an outwardly protruding structure, and the limiting groove 11 can also make way for this outwardly protruding structure. This not only further improves the limiting effect on the clamping part 200, but also facilitates the operator placing the clamping part 200 within the limiting groove 11 without interference.

[0053] In some embodiments, the top surface of the base plate 10 is further provided with a placement groove 12, the fixing seat 20 and the pressure block 30 are disposed in the placement groove 12, the placement groove 12 is connected to the limiting groove 11, and the height of the bottom wall of the placement groove 12 is less than the height of the bottom wall of the limiting groove 11.

[0054] Understandably, both the placement groove 12 and the limiting groove 11 are formed on the top surface of the base plate 10, and the placement groove 12 is connected to the limiting groove 11. The height of the bottom wall of the placement groove 12 is less than the height of the bottom wall of the limiting groove 11. Therefore, the height of the installation position of the pressure block 30 is less than the height of the installation position of the clamping part 200. So when the pressure block 30 abuts against the clamping part 200, the clamping part 200 can contact the center position of the pressure block 30, so that the pressure block 30 can better apply the force to the clamping part 200, and further improve the clamping effect.

[0055] Furthermore, the base plate 10 also includes a baffle 13 connecting the bottom wall of the placement groove 12 and the bottom wall of the limiting groove 11. The baffle 13 faces the surface of the pressing block 30 and is perpendicular to the moving direction of the pressing block 30. The baffle 13 is used to block the pressing block 30 to limit the moving stroke of the pressing block 30.

[0056] Since the height of the bottom wall of the placement groove 12 is less than the height of the bottom wall of the limiting groove 11, a baffle 13 will be formed between the bottom wall of the placement groove 12 and the bottom wall of the limiting groove 11. The baffle 13 is located in the moving stroke of the pressure block 30. When the clamping part 200 is placed in the limiting groove 11, the side of the clamping part 200 facing the pressure block 30 will extend beyond the baffle 13. Therefore, the pressure block 30 will abut against the clamping part 200 and not against the baffle 13. The function of the baffle 13 is to prevent the pressure block 30 from extending too far and causing damage to the clamping part 200.

[0057] In some embodiments, the fixing seat 20 is detachably connected to the base plate 10, and the position of the fixing seat 20 is adjustable along the direction of the pressure block 30 pointing to the clamped part 200.

[0058] The fixing seat 20 is detachably connected to the base plate 10, making it easy to replace. Furthermore, since the position of the fixing seat 20 is adjustable along the direction from the pressure block 30 towards the clamped part 200, its position can be adjusted according to actual needs. For example, when the lateral dimension of the clamped part 200 placed in the limiting groove 11 is small, the fixing seat 20 can be installed closer to the limiting groove 11 for better clamping effect; conversely, when the lateral dimension of the clamped part 200 placed in the limiting groove 11 is large, the fixing seat 20 can be installed further away from the limiting groove 11, allowing the pressure block 30 sufficient retraction space. In other words, the installation position of the fixing seat 20 can be adaptively adjusted according to different models and specifications of clamped parts 200, further improving the applicability of the clamping fixture.

[0059] Specifically, a waist-shaped hole 21 can be opened on the fixed base 20, and a mounting hole 14 corresponding to the waist-shaped hole 21 is opened on the base plate 10. The mounting position of the fixed base 20 can be adjusted by fasteners passing through the waist-shaped hole 21 and the mounting hole 14 respectively.

[0060] In some embodiments, the top surface of the fixing base 20 is provided with a connecting hole 22, and the clamping structure 100 further includes a fastener (not shown in the figure), which is movably inserted through the connecting hole 22 and is used to abut against the side wall of the elastic connector 40 to fix the elastic connector 40.

[0061] like Figure 4 As shown, this application also proposes an optical module adjustment fixture, which includes a clamping structure 100. The specific structure of the clamping structure 100 is as described in the above embodiments. Since this optical module adjustment fixture adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0062] In summary, the clamping structure 100 provided in this application has a limiting groove 11 that can limit the clamped part 200. By placing the pressure block 30 between the fixed base 20 and the clamped part 200, the pressure block 30 can extend towards the limiting groove 11 or retract away from the limiting groove 11, so that for clamped parts 200 of different sizes, the end of the pressure block 30 facing the clamped part 200 can always be tightly attached to and abut against the clamped part 200. This allows for adaptive adjustments based on different models and specifications of clamped parts 200, solving the technical problem of low applicability of existing clamping fixtures, improving versatility, and increasing the applicability of the clamping structure 100.

[0063] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
