And the execution of a plurality of locking positions can be completed through the driving of the linear motor.

Description

Electric sliding plate fastener Technical Field

[0001] This utility model relates to the field of slide rail mating structure, and in particular to an electric fastening machine for sliding plates. Background Technology

[0002] The sliding plate electric fastening machine is similar to a guide rail structure, with a sliding plate slidably mounted on a supporting base. The sliding plate is fixed in place by a linear bearing-like structure. This device is a mechanical device that achieves fastening function through electric drive, mainly used for efficient and precise fastening of sliding plates (such as sliding parts or connecting structures in industrial equipment). Its core function is to use a motor-driven actuator (such as bolts, clamps, etc.) to fix or loosen the target component.

[0003] Fixing the sliding plate with bolts or clamps results in poor tightness. Furthermore, multi-point fixing introduces multiple drive structures, which increases the structural complexity of the system to some extent. Summary of the Invention

[0004] The main objective of this invention is to provide an electric fastening machine for sliding plates, aiming to solve the problems of poor fastening when fixing sliding plates with bolts or clamps, and the increased system complexity caused by introducing multiple drive structures when achieving multi-point fixing.

[0005] To achieve the above objectives, this utility model provides an electric sliding plate fastening machine, wherein the bottom of the sliding plate is provided with a fixing ridge along its length, and the electric sliding plate fastening machine includes:

[0006] Support base, supporting the sliding plate;

[0007] The abutment block pair includes abutment blocks symmetrically arranged on both sides of the fixed edge. The abutment blocks are fixed to the top of the support base. The surface of the abutment block facing the fixed edge is a vertical inclined surface with an angle of 2 to 45 degrees with the length direction of the sliding plate.

[0008] A pair of sliding blocks includes two sliders, which are slidably disposed in a groove-fitting manner with the abutment block along the length direction of the inclined surface. The surface of the slider facing the fixed edge is vertical and parallel to the fixed edge.

[0009] The operating bracket includes a horizontal bracket and a vertical bracket connected to the horizontal bracket. The vertical bracket is arranged collinearly with the fixed edge in the vertical direction and has a limiting groove on each side. The length direction of the limiting groove is perpendicular to the inclined surface. The slider is locked in the limiting groove and slides in the length direction of the limiting groove.

[0010] A linear motor drives the sliding plate to extend and retract along its length, and its output end is connected to the transverse support.

[0011] During the movement of the operating bracket, the limiting groove drives the slider to slide on the abutment block, thereby enabling the slider to separate from and engage with the fixed edge.

[0012] Furthermore, the slider is provided with a dovetail ridge, and the abutment block is provided with a dovetail groove corresponding to the dovetail ridge.

[0013] Furthermore, a lubricating oil groove is provided on the interface where the slider and the abutment block form a groove.

[0014] Furthermore, the inclined surface is at an angle of 5 to 10 degrees to the fixed edge.

[0015] Furthermore, the linear motor drive and the transverse support are detachably connected.

[0016] Furthermore, the end of the limiting groove that is away from the fixed edge in the length direction is open.

[0017] Furthermore, the slider is in contact with the bottom surface of the sliding plate.

[0018] Furthermore, the abutment blocks are fixed to the support base by bolts.

[0019] Furthermore, the transverse support and the longitudinal support are connected by bolts.

[0020] Furthermore, the sliding plate electric fastening machine also includes a housing;

[0021] The support base is disposed inside the housing, and the sliding plate extends out of the housing.

[0022] The sliding plate electric fastening machine provided by this utility model has an operating bracket that extends and retracts along with the linear motor during the extension and retraction process. The slider, which is locked in the limiting groove, slides on the abutment block. Due to the action of the inclined surface on the abutment block, the slider also slides in the length direction of the limiting groove, thereby changing the distance between it and the fixed edge. When the slider abuts against the fixed edge, the two sliders in pairs clamp the fixed edge, and the slider and the fixed edge form a large frictional force in the length direction, thereby locking the sliding plate. Moreover, multiple locking positions can be executed by driving the linear motor. Attached Figure Description

[0035] Referring to Figures 1 to 9, in one embodiment of the present invention, a sliding plate electric fastening machine is provided, wherein the bottom of the sliding plate 010 is provided with a fixing rib 011 along the length direction, and the sliding plate electric fastening machine includes:

[0036] Support base 100 supports the sliding plate 010;

[0037] The abutment block pair includes abutment blocks 210 symmetrically arranged on both sides of the fixed edge 011. The abutment blocks 210 are fixed to the top of the support base 100. The surface of the abutment block 210 facing the fixed edge 011 is a vertical inclined surface 211 with an angle of 2 to 45 degrees with the length direction of the sliding plate 010.

[0038] The sliding block pair includes two sliders 310. The sliders 310 and the abutment block 210 are slidably disposed in a groove-fitting manner along the length direction of the inclined surface 211. The surface of the slider 310 facing the fixed edge 011 is vertical and parallel to the fixed edge 011.

[0039] The operating bracket includes a horizontal bracket 410 and a vertical bracket 420 connected to the horizontal bracket 410. The vertical bracket 420 is arranged collinearly with the fixed edge 011 in the vertical direction and has a limiting groove 421 on each side. The length direction of the limiting groove 421 is perpendicular to the inclined surface 211. The slider 310 is fixed in the limiting groove 421 and slides in the length direction of the limiting groove 421.

[0040] A linear motor drive 500 extends and retracts along the length of the sliding plate 010 and its output end is connected to the transverse support 410.

[0041] During the movement of the operating bracket, the limiting groove 421 drives the slider 310 to slide on the abutment block 210, thereby enabling the slider 310 to separate from and engage with the fixed ridge 011.

[0042] In existing technologies, fixing the sliding plate with bolts or clamps has the problem of poor tightness. At the same time, when multi-point fixing is achieved, multiple driving structures are also introduced, which increases the structural complexity of the system to a certain extent.

[0043] The sliding plate electric fastening machine provided by this utility model has at least one fixing ridge 011 provided along the length direction of the bottom of the sliding plate 010. The cross-section of the fixing ridge 011 is rectangular. The sliding plate electric fastening machine includes:

[0044] The support base 100 supports the sliding plate 010. The support base 100 can support the sliding plate 010 by means of linear bearings or the like, so that the sliding plate 010 can slide in the length direction of the support base 100.

[0045] The abutment block pair includes abutment blocks 210 symmetrically arranged on both sides of the fixed edge 011. The abutment blocks 210 are fixed to the top of the support base 100. The fixing method of the abutment blocks 210 on the support base 100 can be various and is not limited. The surface of the abutment block 210 facing the fixed edge 011 is a vertical inclined surface 211 with an angle of 2 to 45 degrees with the length direction of the sliding plate 010. The inclination of the inclined surface 211 provides a basis for the operation of the subsequent slider 310.

[0046] The sliding block pair includes two sliders 310. The sliders 310 and the supporting block 210 are slidably configured by forming a groove engagement along the length of the inclined surface 211. For example, a dovetail ridge 311 is provided on the slider 310, and a dovetail groove 212 corresponding to the dovetail ridge 311 is provided on the supporting block 210. Through the shape limitation, the groove engagement between the slider 310 and the supporting block 210 allows for sliding in the length direction while remaining fixed in other directions, thus making the operation of the slider 310 smoother. The surface of the slider 310 facing the fixed ridge 011 is vertical and parallel to the fixed ridge 011. When the slider 310 slides on the supporting block 210, the distance between the slider 310 and the fixed ridge 011 changes, thereby achieving locking and releasing.

[0047] The operating support includes a transverse support 410 and a longitudinal support 420 connected to the transverse support 410. The number of longitudinal supports 420 corresponds to the number of fixed edges 011. The longitudinal supports 420 are arranged collinearly with the fixed edges 011 in the vertical direction, that is, their projections coincide. A limiting groove 421 is provided on each side of the longitudinal support 420. The length direction of the limiting groove 421 is perpendicular to the inclined surface 211. The slider 310 is locked in the limiting groove 421 and slides in the length direction of the limiting groove 421. During the sliding of the slider 310 in the length direction of the limiting groove 421, the distance between it and the fixed edge 011 changes. When the slider 310 abuts against the fixed edge 011, the two sliders 310 in pairs clamp the fixed edge 011, and the slider 310 and the fixed edge 011 generate a large frictional force in the length direction, thereby locking the sliding plate 010; when the slider 310 does not abut against the fixed edge 011, the sliding plate 010 is free. The greater the angle of the inclined surface 211, the more difficult it is for the slider 310 to slide on the limiting groove 421 and the abutment block 210.

[0048] The linear motor drive 500 extends and retracts along the length of the sliding plate 010, and its output end is connected to the transverse support 410. The linear motor drive 500 is a motor-driven type. During the extension and retraction of the linear motor drive 500, the operating support extends and retracts accordingly. The slider 310, which is locked in the limiting groove 421, slides on the abutment block 210. Due to the action of the inclined surface 211 on the abutment block 210, the slider 310 also slides along the length of the limiting groove 421, thereby changing the distance between it and the fixed edge 011. Multiple locking positions can be executed by the linear motor drive 500.

[0049] In summary, during the extension and retraction of the linear motor drive 500, the operating bracket extends and retracts accordingly. The slider 310, which is locked in the limiting groove 421, slides on the abutment block 210. Due to the action of the inclined surface 211 on the abutment block 210, the slider 310 also slides in the length direction of the limiting groove 421, thereby changing the distance between it and the fixed edge 011. When the slider 310 abuts against the fixed edge 011, the two sliders 310 in pairs clamp the fixed edge 011, and the slider 310 and the fixed edge 011 form a large frictional force in the length direction, thereby locking the sliding plate 010. The linear motor drive 500 can complete the execution of multiple locking positions.

[0050] Referring to Figures 2 and 3, in one embodiment, the slider 310 is provided with a dovetail ridge 311, and the abutment block 210 is provided with a dovetail groove 212 corresponding to the dovetail ridge 311.

[0051] In this embodiment, the groove between the shape-defined slider 310 and the abutment block 210 allows for sliding in the length direction while remaining fixed in other directions, thus making the operation of the slider 310 smoother.

[0052] In one embodiment, a lubricating oil groove is provided on the interface where the slider 310 and the abutment block 210 form a groove.

[0053] In this embodiment, by introducing a lubricating oil groove, when lubricating oil is added between the slider 310 and the supporting block 210, the residence time of the lubricating oil can be extended to a certain extent.

[0054] In one embodiment, the inclined surface 211 is at an angle of 5 to 10 degrees to the fixed edge 011.

[0055] In this embodiment, the angle of the inclined surface 211 is limited, so that the slider 310 can slide smoothly on the abutment block 210 while the slider 310 can clamp the fixed edge 011 relatively stably. If the angle of the inclined surface 211 is too large, the sliding process of the slider 310 will have too much resistance; if the angle of the inclined surface 211 is too small, the interaction between the slider 310 and the fixed edge 011 will be weak, thus affecting the fastening effect.

[0056] In one embodiment, the linear motor drive 500 and the transverse support 410 are detachably connected.

[0057] In this embodiment, the connection between the linear motor drive 500 and the transverse support 410 is restricted to be detachable. This allows for the installation of the operating support and the sliding block pair to be completed first, and then the transverse support 410 to be connected to the linear motor drive 500. This simplifies the installation process of the sliding block pair and the operating support, and the above installation process is also the position initialization process.

[0058] In one embodiment, the end of the limiting groove 421 that is away from the fixed ridge 011 in the length direction is open.

[0059] In this embodiment, one end of the limiting groove 421 is left open, thereby simplifying the installation and maintenance of the slider 310 and saving materials.

[0060] In one embodiment, the slider 310 is in contact with the bottom surface of the sliding plate 010.

[0061] In this embodiment, by adding guidance to the slider 310, the sliding process of the slider 310 is made smoother. In particular, vertical adjustment is eliminated, simplifying the alignment process between the slider 310 and the abutment block 210.

[0062] In one embodiment, the abutment blocks are bolted to the support base 100.

[0063] In this embodiment, the connection between the abutment block and the support base 100 is limited to a bolt connection, which optimizes the connection process and facilitates installation and maintenance.

[0064] In one embodiment, the transverse support 410 and the longitudinal support 420 are bolted together.

[0065] In this embodiment, the connection between the longitudinal support 420 and the transverse support 410 is limited to a bolt connection, which optimizes the connection process and facilitates installation and maintenance.

[0066] In one embodiment, the sliding plate electric fastening machine further includes a housing 600;

[0067] The support base 100 is disposed inside the housing 600, and the sliding plate 010 extends out of the housing 600.

[0068] In this embodiment, a housing 600 is added to protect the support base 100, the operating bracket, and the linear motor drive 500 to prevent foreign objects from entering and to ensure the operation of the operating bracket.

[0069] In summary, the sliding plate electric fastening machine provided by this utility model, during the extension and retraction of the linear motor drive 500, the operating bracket extends and retracts accordingly. The slider 310, which is locked in the limiting groove 421, slides on the abutment block 210. Due to the action of the inclined surface 211 on the abutment block 210, the slider 310 also slides in the length direction of the limiting groove 421, thereby changing the distance between it and the fixed edge 011. When the slider 310 abuts against the fixed edge 011, the two sliders 310 in pairs clamp the fixed edge 011, and the slider 310 and the fixed edge 011 form a large frictional force in the length direction, thereby locking the sliding plate 010. Moreover, multiple locking positions can be executed by the linear motor drive 500.

[0070] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
