Description

Technical Field

[0001] This application belongs to the field of workpiece positioning technology, and specifically relates to a locking device. Background Technology

[0002] The workpiece can support and position multiple materials. After the workpiece is positioned on the working platform of the processing equipment, the equipment can process the materials within the workpiece. Traditionally, the workpiece is locked to the working platform using threaded fasteners such as screws or bolts, which is a relatively complex operation. Utility Model Content

[0003] In view of the above, it is necessary to provide a locking device that can quickly lock the second workpiece to the first workpiece.

[0004] This application provides a locking device for locking a second workpiece to a first workpiece. The locking device includes a base, a latching assembly, a driving member, and two fastening members. The two fastening members are spaced apart along a first direction and are used to connect the same first workpiece. Each of the two fastening members has a slot on its adjacent side. The base is located between the two fastening members and is used to connect the second workpiece. The latching assembly includes two latching members, both of which are located on the base. Each latching member includes a latch head, which is movable relative to the base and passes through the base. The driving member connects the two latching members and drives corresponding latch heads of the two latching members to move relative to each other along the first direction, so that each latch head inserts into a slot.

[0005] In the aforementioned locking device, the two corresponding latches of the two latching members are driven by a driving component to move closer together, causing them to retract into the base. At this point, the base can be placed between the two fastening members. The driving component then drives the two latches to move away from each other, causing them to extend out of the base. Each latch then inserts into a slot, meaning the base is held between the two fastening members by the latching assembly. Applying the locking device to both the first and second workpieces—connecting the two fastening members to the same first workpiece and the base to the second workpiece—means that when the base is held between the two fastening members by the latching assembly, the second workpiece is locked to the first workpiece. Therefore, by driving the two latches to move relative to each other, the second workpiece can be quickly locked to the first workpiece, making the operation simple and convenient.

[0006] In some embodiments, the snap-fit ​​assembly further includes a first elastic element, which is connected to two snap-fit ​​members respectively along a first direction, and the first elastic element rebounds to allow the snap-fit ​​head to be inserted into the snap-fit ​​slot.

[0007] In some embodiments, the snap-fit ​​assembly further includes a pivot shaft disposed on the base, with two snap-fit ​​members arranged crosswise, and the pivot shaft passing through the intersection area of ​​the two snap-fit ​​members, so that the two snap-fit ​​members can rotate around the pivot shaft.

[0008] In some embodiments, each snap-fit ​​component includes a rod and two snap heads, a drive member is connected to the rod, and a rotating shaft passes through the rod; in each snap-fit ​​component, the two snap heads are respectively located at opposite ends of the rod along a second direction, and the two snap heads are respectively located on opposite sides of the rod along a first direction, the second direction being perpendicular to the first direction.

[0009] In some embodiments, each fastener includes a main body and an extension block, each extension block being connected to one side of two main bodies facing each other to form a slot; the extension block includes a first inclined surface and a first stop surface, the first inclined surface and the first stop surface being respectively disposed on opposite sides of the extension block along a third direction, the third direction being perpendicular to the first direction, the first inclined surface being inclined toward the first stop surface and used to guide the card head to move into the slot along the third direction, the first stop surface being used to abut against the card head to restrict the movement of the card head toward the first inclined surface along the third direction.

[0010] In some embodiments, the card head includes a second inclined surface and a second stop surface, the second inclined surface and the second stop surface are respectively disposed on opposite sides of the card head along a third direction, the second inclined surface is inclined toward the second stop surface, the second inclined surface is used to move along the first inclined surface into the card slot, and the second stop surface is used to abut against the first stop surface.

[0011] In some embodiments, the driving member includes two pressing blocks, each pressing block being connected to a snap-fit ​​member, and the base having an opening extending through in a third direction. Both pressing blocks pass through the opening, which extends in a first direction, allowing the two pressing blocks to move relative to each other in the first direction.

[0012] In some embodiments, each pressing block is connected to a push rod, and each snap-fit ​​is connected to a stop block. Both the push rod and the stop block extend in a third direction, such that the two push rods are respectively located on opposite sides of the two stop blocks.

[0013] In some embodiments, the drive member further includes a second elastic member, which is connected to two pressing blocks along the first direction. The second elastic member rebounds to move the two pressing blocks away from each other.

[0024] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] In the description of the embodiments of this application, the technical terms "first", "second", etc. are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.

[0028] In the description of the embodiments of this application, the term "perpendicular" is used to describe the ideal state between two components. In actual production or use, two components may be in a state that is approximately perpendicular. The term "parallel" is used to describe the ideal state between two components. In actual production or use, two components may be in a state that is approximately parallel.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0030] The workpiece can support and position multiple materials. After the workpiece is positioned on the working platform of the processing equipment, the equipment can process the materials within the workpiece. Traditionally, the workpiece is locked to the working platform using threaded fasteners such as screws or bolts, which is a relatively complex operation.

[0031] This application provides a locking device for locking a second workpiece to a first workpiece. The locking device includes a base, a latching assembly, a driving member, and two fastening members. The two fastening members are spaced apart along a first direction and are used to connect the same first workpiece. Each of the two fastening members has a slot on its adjacent side. The base is located between the two fastening members and is used to connect the second workpiece. The latching assembly includes two latching members, both of which are located on the base. Each latching member includes a latch head, which is movable relative to the base and passes through the base. The driving member connects the two latching members and drives corresponding latch heads of the two latching members to move relative to each other along the first direction, so that each latch head inserts into a slot.

[0032] In the aforementioned device, the two corresponding latches of the two latching members are driven by a driving component to move closer together, causing them to retract into the base. At this point, the base can be placed between the two fastening members. The driving component then drives the two latches to move away from each other, causing them to extend out of the base. Each latch then inserts into a slot, meaning the base is held between the two fastening members by the latching assembly. Applying the locking device to both the first and second workpieces involves connecting the two fastening members to the same first workpiece and connecting the base to the second workpiece. When the base is held between the two fastening members by the latching assembly, the second workpiece is locked to the first workpiece. Therefore, by driving the two latches to move relative to each other, the second workpiece can be quickly locked to the first workpiece, making the operation simple and convenient.

[0033] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.

[0034] Please see Figure 1 and Figure 2 An embodiment of this application provides a locking device 100 for locking a second workpiece 300 to a first workpiece 200.

[0035] In some embodiments, the first workpiece 200 is a working platform of the processing equipment. The second workpiece 300 is a carrier. The second workpiece 300 is provided with a plurality of mounting positions 3002, each mounting position 3002 being able to hold and position a material. The locking device 100 positions the first workpiece 200 on the second workpiece 300, which facilitates the processing equipment to process multiple materials.

[0036] In some embodiments, the first workpiece 200 is provided with a receiving groove 2002 for receiving the second workpiece 300 to position the second workpiece 300 along the first direction Y. (See also...) Figure 3 The receiving groove 2002 has two first alignment holes 2001, and the first workpiece 200 has two second alignment holes 3001. The first and second alignment holes 2001 and 3001 accommodate the insertion of an alignment pin 210 to position the second workpiece 300 horizontally. The alignment pin 210 can also be fixedly disposed in the first alignment hole 2001, so that when the second workpiece 300 is located in the receiving groove 2002, the alignment pin 210 is directly inserted into the second alignment hole 3001. In the illustrated embodiment, the first direction Y is parallel to the horizontal direction.

[0037] Please see Figures 3 to 5 In some embodiments, the locking device 100 includes a base 20, a latching assembly 30, a driving member 40, and two fastening members 10. The two fastening members 10 are spaced apart along a first direction Y. The latching assembly 30 is disposed on the base 20, allowing the base 20 to be latched onto the two fastening members 10. The driving member 40 is connected to the latching assembly 30. The driving member 40 can drive the latching assembly 30 to latch onto the fastening members 10, thereby securing the base 20 between the two fastening members 10; the driving member 40 can also drive the latching assembly 30 to release the latching members 10, allowing the base 20 to separate from the two fastening members 10.

[0038] The lower surfaces of the two fastening members 10 are configured to connect to the upper surface of the same first workpiece 200. The lower surface of the base 20 is configured to connect to the upper surface of the second workpiece 300. When the base 20 is engaged between the two fastening members 10 by the snap-fit ​​assembly 30, the base 20 presses the second workpiece 300 against the first workpiece 200 to position the second workpiece 300 in the third direction Z to prevent the second workpiece 300 from moving relative to the first workpiece 200.

[0039] In some embodiments, the fastener 10 is connected to the first workpiece 200, and the base 20 is connected to the second workpiece 300 by threaded fasteners. Threaded fasteners include screws or bolts.

[0040] In some embodiments, the third direction Z is parallel to the vertical direction. In the illustrated embodiment, the third direction Z refers to the stacking direction of the second workpiece 300 and the first workpiece 200.

[0041] Please see Figure 3 In some embodiments, a slot 101 is provided on the side of the two fastening members 10 that are close to each other. Please refer to [link / reference]. Figures 3 to 5 The snap-fit ​​assembly 30 includes two snap-fit ​​members 31, both of which are disposed on the base 20. Each snap-fit ​​member 31 includes a snap head 312, which passes through the base 20 and is movable relative to the base 20 so that the snap head 312 can retract into or extend out of the base 20.

[0042] The driving component 40 connects to two snap-fit ​​components 31 and can drive the corresponding snap-fit ​​heads 312 in the two snap-fit ​​components 31 to move relative to each other. When the driving component 40 drives the corresponding snap-fit ​​heads 312 to move closer to each other along the first direction Y, the snap-fit ​​heads 312 retract into the base 20, at which time the base 20 can move relative to the two fastening components 10. When the driving component 40 drives the two snap-fit ​​heads 312 to move away from each other along the first direction Y, the snap-fit ​​heads 312 extend out of the base 20 until each snap-fit ​​head 312 is inserted into a snap-fit ​​slot 101, at which time the base 20 is held between the two fastening components 10 by the snap-fit ​​assembly 30.

[0043] Please see Figure 7 In some embodiments, the base 20 has a cavity 201, and the snap-fit ​​assembly 30 is installed in the cavity 201.

[0044] Please see Figures 3 to 7 In some embodiments, the snap-fit ​​assembly 30 further includes a first elastic element 32. Along the first direction Y, the first elastic element 32 is connected to two snap-fit ​​members 31. When the corresponding two snap-fit ​​heads 312 move closer together, the first elastic element 32 is elastically compressed. The rebound of the first elastic element 32 allows the snap-fit ​​head 312 to be inserted into the snap-fit ​​slot 101.

[0045] Without external force, the first elastic member 32 can keep the locking head 312 in the locking groove 101 so that the base 20 and the two fastening members 10 are kept in the locking state.

[0046] In some embodiments, the snap-fit ​​member 31 is slidably connected to the base 20 along the first direction Y, so that the snap-fit ​​head 312 can move relative to the base 20 to retract into or extend out of the base 20.

[0047] In some embodiments, the snap-fit ​​assembly 30 further includes a pivot 33. The pivot 33 extends in a third direction Z and is fixedly mounted on the base 20. Two snap-fit ​​members 31 are arranged crosswise, and the pivot 33 passes through the intersection area of ​​the two snap-fit ​​members 31, allowing the two snap-fit ​​members 31 to be rotatably connected via the pivot 33. The two snap-fit ​​members 31 can rotate around the pivot 33, allowing the snap-fit ​​head 312 to extend or retract into the base 20.

[0048] The two card contacts 31 are arranged in a cross configuration, and can be driven by the drive unit 40 to rotate the two card contacts 31 relative to each other, so that the card head 312 can be inserted into or removed from the card slot 101, which is convenient to operate; the two card contacts 31 are always connected through the rotating shaft 33, so that the two card contacts 31 are tightly connected, with good stability and reliability.

[0049] In some embodiments, each snap-fit ​​member 31 includes a rod portion 311 and two snap heads 312. A drive member 40 connects to the rod portion 311, and a rotating shaft 33 passes through the center of the rod portion 311 along the second direction X. In each snap-fit ​​member 31, two snap heads 312 are respectively disposed at opposite ends of the rod portion 311 along the second direction X, and two snap heads 312 are respectively disposed on opposite sides of the rod portion 311 along the first direction Y. Each fastening member 10 is provided with two slots 101, each slot 101 for accommodating one snap head 312.

[0050] The two snap-fit ​​pieces 31 each have two pairs of corresponding snap heads 312. When the two rods 311 are driven to rotate relative to each other by the drive member 40, the two snap heads 312 located at both ends of the rods 311 move simultaneously with the rods 311. The two pairs of snap heads 312 can move relative to each other or relative to each other by the same distance at the same time. The snap heads 312 in the two snap-fit ​​pieces 31 can be inserted into the corresponding slots 101 at the same time or withdrawn from the corresponding slots 101 at the same time.

[0051] By inserting multiple clips 312 into multiple slots 101, the connection between the fastener 10 and the base 20 becomes more stable and less prone to shaking.

[0052] In some embodiments, the second direction X and the first direction Y are two perpendicular horizontal directions. In the illustrated embodiment, the first direction Y refers to the width direction of the base 20, the second direction X refers to the length direction of the base 20, and the third direction Z refers to the height direction of the base 20.

[0053] Please see Figure 3 and Figure 4 In some embodiments, the facing surfaces of the two corresponding slots 101 in the two fastening members 10 are defined as the first contact surface 123. The side of the latch head 312 facing the fastening member 10 is defined as the second contact surface 3123. The rod portion 311 is bent so that when the latch head 312 is inserted into the slot 101, the first contact surface 123 and the second contact surface 3123 are parallel and in contact with each other, thereby allowing the latch head 312 to be more stably held in the slot 101 (see reference). Figure 1 and Figure 2 ).

[0054] Please see Figure 3 and Figure 4 In some embodiments, each fastener 10 includes a main body 11 and two extension blocks 12. Each extension block 12 is connected to the two main bodies 11 facing each other. When the latch 312 is inserted into the slot 101, along the third direction Z, the extension block 12 is located on the side of the latch 312 facing away from the second workpiece 300, that is, the latch 312 is clamped between the second workpiece 300 and the extension block 12.

[0055] In some embodiments, in the two fastening members 10, along the first direction Y, the distance between the two first contact surfaces 123 is greater than the distance between the two main body portions 11 for connecting the extension block 12. Thus, the slot 101 is recessed into the main body portion 11, and when the card head 312 is engaged in the slot 101, the fastening member 10 can position the base 20 in both the horizontal and vertical directions.

[0056] Please see Figure 3 and Figure 4 In some embodiments, the first contact surface 123 coincides with the side of the main body 11 used to connect the extension block 12. Thus, each extension block 12 can form a slot 101 by connecting to the main body 11. When the card head 312 is engaged in the slot 101, the fastener 10 can position the base 20 in the third direction Z.

[0057] If the first alignment hole 2001 and the second alignment hole 3001 are not aligned when the clasp 312 is held in the clasp 101, the position of the second workpiece 300 can be adjusted by driving the base 20 to move the second workpiece 300 along the second direction X until the first alignment hole 2001 is aligned with the second alignment hole 3001. Then, the alignment pin 210 is inserted into the first alignment hole 2001 and the second alignment hole 3001 to position the second workpiece 300 and the first workpiece 200 along the second direction X.

[0058] Please see Figure 3 and Figure 4In some embodiments, the extension block 12 includes a first inclined surface 121 and a first stop surface 122. Along the third direction Z, the first inclined surface 121 and the first stop surface 122 are respectively disposed on opposite sides of the extension block 12, and the first inclined surface 121 is inclined toward the first stop surface 122.

[0059] When the base 20 moves toward the fastening member 10, the first inclined surface 121 abuts against and guides the locking head 312 to move toward the slot 101 along the third direction Z. The first elastic member 32 is elastically compressed until the locking head 312 enters the slot 101. Then, the first elastic member 32 rebounds. At this time, the first stop surface 122 abuts against the locking head 312 to restrict the locking head 312 from moving toward the first inclined surface 121 along the third direction Z, thereby restricting the locking head 312 in the slot 101 along the third direction Z. That is, the base 20 presses the second workpiece 300 against the first workpiece 200 along the third direction Z (see reference). Figure 1 and Figure 2 ).

[0060] Please see Figures 3 to 5 In some embodiments, the card head 312 includes a second inclined surface 3121 and a second stop surface 3122. Along the third direction Z, the second inclined surface 3121 and the second stop surface 3122 are respectively disposed on opposite sides of the card head 312, and the second inclined surface 3121 is inclined toward the second stop surface 3122.

[0061] When the base 20 moves toward the fastening member 10, the second inclined surface 3121 moves along the first inclined surface 121, allowing the locking head 312 to enter the slot 101 more smoothly. After the locking head 312 enters the slot 101, the second stop surface 3122 abuts against the first stop surface 122, so that the first stop surface 122 can restrict the locking head 312 from moving toward the first inclined surface 121 in the third direction Z (see reference). Figure 1 and Figure 2 ).

[0062] In the illustrated embodiment, both the first stop surface 122 and the second stop surface 3122 are parallel to the horizontal plane.

[0063] Please see Figure 2 and Figure 6 In some embodiments, the drive member 40 includes two pressing blocks 41, each pressing block 41 being fixedly connected to a snap-fit ​​member 31. The base 20 has an opening 202 extending through it in a third direction Z, through which both pressing blocks 41 pass. The opening 202 extends in a first direction Y, allowing the two pressing blocks 41 to move relative to each other within the opening 202 in the first direction Y. When the two pressing blocks 41 approach each other, the snap-fit ​​member 312 retracts into the base 20; when the two pressing blocks 41 move away from each other, the snap-fit ​​member 312 extends out of the base 20 and inserts into the snap-fit ​​slot 101.

[0064] In some embodiments, the pressing block 41 is fixedly connected to one end of the rod 311 near a locking head 312, and the rod 311 can be easily rotated by pinching the pressing block 41.

[0065] Please see Figure 1 , Figure 3 and Figure 5 In some embodiments, each pressing block 41 is fixedly connected to a push rod 411. The rod portion 311 of each snap-fit ​​member 31 is fixedly connected to a stop block 3111. Both the push rod 411 and the stop block 3111 extend along a third direction Z, such that the two push rods 411 are respectively located on opposite sides of the two stop blocks 3111.

[0066] When the operator drives the two pressing blocks 41 to move closer to each other, the two push rods 411 drive the two stop blocks 3111 to move closer to each other, causing the locking head 312 to retract into the base 20; when the two pressing blocks 41 are released, the first elastic element 32 rebounds, causing the locking head 312 to extend out of the base 20 and insert into the locking slot 101, and the two stop blocks 3111 push against the two rods 311 to move the two pressing blocks 41 away from each other.

[0067] Please see Figure 5 In some embodiments, the drive member 40 further includes a second elastic member 42. Along the first direction Y, the second elastic member 42 is connected to two pressing blocks 41 respectively. When the two pressing blocks 41 move closer to each other, the second elastic member 42 is elastically compressed, at which point the locking head 312 retracts into the base 20. The rebound of the second elastic member 42 causes the two pressing blocks 41 to move further apart, at which point the locking head 312 inserts into the locking slot 101.

[0068] Without external force, the second elastic element 42 can make the two pressing blocks 41 move away from each other, that is, the locking head 312 is locked in the locking groove 101, so that the base 20 and the two fastening parts 10 are more stably held in the locking state.

[0069] Please see Figures 1 to 6 In some embodiments, the locking device 100 further includes a gripper 50. The gripper 50 is fixedly disposed on the base 20. The side of the base 20 for connecting the second workpiece 300 and the side of the base 20 for connecting the gripper 50 are disposed opposite each other along a third direction Z.

[0070] The operator can hold the grip 50 and move the base 20 and the second workpiece 300 connected to the base 20. While holding the grip 50, the operator can also squeeze the pressing block 41 to make the pressing block 41 move relative to the base, which is convenient to operate.

[0071] Please see Figure 1 , Figures 3 to 5In some embodiments, the gripper 50 is provided with a receiving cavity 501, within which the pressing block 41 is movable in a first direction Y to allow the card head 312 to be inserted into the card slot 101. The receiving cavity 501 can accommodate at least partially the pressing block 41 to protect the second elastic member 42 and the pressing block 41.

[0072] In use, the operator holds the gripper 50, driving the base 20 to move the second workpiece 300 toward the first workpiece 200, aligning the second workpiece 300 with the mounting position 3002 and the first alignment hole 2001 with the second alignment hole 3001; pressing down the base 20 and the second workpiece 300 causes the locking head 312 to retract into the base 20 under the pressure of the first inclined surface 121, and the second workpiece 300 enters the receiving groove 2002 and presses against the first workpiece 200; the first elastic member 32 rebounds, causing the locking head 312 to extend, each locking head 312 inserting into a locking slot 101, so that the base 20 is held between the two fastening members 10 by the locking assembly 30; the alignment pin 210 is inserted into the first workpiece 200 and the second workpiece 300, at which point the second workpiece 300 is positioned relative to the first workpiece 200 (see reference). Figure 1 and Figure 2 ).

[0073] The processing equipment processes multiple materials carried by the first workpiece 200. By squeezing the two pressing blocks 41, the clamping head 312 retracts into the base 20. The hand-held grip 50 drives the base 20 to move the second workpiece 300 away from the first workpiece 200, thus removing the processed materials and the second workpiece 300 carrying the materials (see reference). Figure 3 ).

[0074] The operator can operate with one hand to quickly position the second workpiece 300 on the first workpiece 200, making the operation simple, convenient and fast.

[0075] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
