Description

Technical Field

[0001] The present application relates to the technical field of optical equipment, and in particular to a positioning fixture and a locking device. Background Art

[0002] When the camera equipment uses screws to lock the camera back cover pressure plate and the locking component, the operator needs to press the spring by hand to lock it because the back cover pressure plate has a spring structure inside. In addition, since there is no positioning mechanism between the screw hole and the screw guide of the locking component, it is easy to offset after assembly. Therefore, the operator needs to use one hand to straighten the back cover pressure plate when locking, resulting in very low work efficiency and the locking quality cannot be guaranteed. Summary of the invention

[0003] The present application provides a positioning fixture and a locking device, which can not only improve the working efficiency but also improve the locking quality.

[0004] In a first aspect, the present application provides a positioning fixture, comprising a fixture base plate, a silicone mold, and a pressure plate module;

[0006] The silicone mold is provided with a slot matching the shape of the product, and the slot is used to place the product and the locking component;

[0007] The pressing plate module can be rotatably connected to the jig bottom plate relative to the jig bottom plate, and the pressing plate module includes a pressing block. When the pressing plate module is in a first position, the pressing block is pressed on a side of the locking component away from the product, and when the pressing plate module is in a second position, the pressing block is out of the state of being pressed on the locking component.

[0008] The pressing block is provided with a positioning groove, and when the pressing block module is in the first station, the positioning groove is used to position the locking component.

[0009] The positioning jig provided in the present application realizes precise positioning between the product and the locked product by setting a jig base plate, a silicone mold and a pressure plate module. The jig base plate can provide strong support for the silicone mold, and the shape of the card slot set in the silicone mold matches the shape of the product, which can make the product and the card slot engage, ensuring the positioning between the product and the jig base plate. When the pressure plate module is in the first station, the pressing block is pressed against the locking component, so that the locking component and the product remain relatively fixed, and the positioning groove of the pressing block can position the locking component, so that the locking component and the product are accurately positioned. After the product and the locking component are positioned, in the process of locking the product and the locking component, the pressing block can be always pressed against the locking component, eliminating the workload of the operator to manually straighten the product. Therefore, the positioning jig in the present application can not only ensure the precise positioning between the product and the locking component, ensure the locking quality, improve the product quality, but also help to improve the operating efficiency.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] refer to Figure 1 and Figure 2 The positioning device in the embodiment of the present application may include a fixture base plate 100, a silicone mold 200 and a pressure plate module 300, wherein a groove 110 is provided in the middle of the fixture base plate 100, and the groove 110 can be used to embed the silicone mold 200. The fixture base plate 100 has a bearing portion 120 located around the groove 110, and the pressure plate module 300 can be connected to the bearing portion 120.

[0032] The material of the fixture bottom plate 100 can be black bakelite, which has stable performance and can provide a strong supporting foundation for the entire fixture.

[0033] For details, please refer to Figures 1 to 4 The silicone mold 200 is provided with a card slot 210 that matches the shape of the product 10, and the product 10 can be placed in the card slot 210 so that the card slot 210 limits the position of the product 10. Due to the material of the silicone mold 200, when the product 10 is placed in the card slot 210, the silicone mold 200 can produce a certain deformation without scratching the product 10. In addition, after the product 10 is placed in the card slot 210, the locking component 20 can be placed on the product 10 to facilitate the subsequent positioning and locking of the locking component 20 and the product 10. It is worth mentioning that the product 10 in this embodiment can be understood as a camera back cover pressure plate.

[0034] The pressing plate module 300 can rotate relative to the fixture base plate 100. The pressing plate module 300 includes a pressing block 310. When the pressing plate module 300 is in the first position, the pressing block 310 can be regarded as being parallel to the surface of the bearing portion 120. At this time, at least a portion of the pressing block 310 is directly opposite to the card slot 210. In other words, when the pressing plate module 300 is in the first position, a portion of the pressing plate contacts the bearing portion 120 so that the bearing portion 120 can limit the pressing block 310. Another portion of the pressing block 310 is in a suspended state so that this portion of the pressing block 310 can be pressed against the side of the locking component 20 away from the product 10, thereby keeping the locking component 20 and the product 10 relatively fixed. When the pressing plate module 300 is in the second position, the pressing block 310 is away from the card slot 210. At this time, the pressing block 310 is out of the state of being pressed against the locking component 20.

[0035] In some embodiments, reference Figure 5 and Figure 6The pressing plate module 300 includes a connecting plate 320 and two pressing blocks 310, wherein the connecting plate 320 is located on the bearing portion 120, and the two pressing blocks 310 are respectively connected to opposite ends of the connecting plate 320. The pressing blocks 310 and the connecting plate 320 can be fixedly connected, and the connecting plate 320 can rotate relative to the fixture base plate 100. When the pressing plate module 300 is switched from the first station to the second station or from the second station to the first station, the connecting plate 320 can rotate relative to the fixture base plate 100, thereby driving the two pressing blocks 310 to move synchronously.

[0036] The two pressing blocks 310 can be pressed and attached to the two ends of the locking component 20 respectively, so that the pressure plate module 300 can better position the locking component 20. In addition, the two pressing blocks 310 can be symmetrically arranged, and a positioning groove 311 can be arranged on the side of each pressing block 310 facing the other pressing block 310. On the one hand, the positioning groove 311 can be used to avoid the end structure of the locking component 20 to avoid collision between the pressing block 310 and the locking component 20. On the other hand, the two positioning grooves 311 cooperate to position the locking component 20. At this time, since the product 10 has been fixed in the silicone mold 200, the locking component 20 is limited by the pressing block 310, thereby ensuring the positioning effect between the product 10 and the locking component 20.

[0037] Furthermore, if Figure 1 As shown, the pressure plate module 300 also includes a pressure plate handle 360, which is fixedly connected to the side of the connecting plate 320 away from the bearing portion 120. Specifically, the pressure plate handle 360 ​​can be an L-shaped structure, which includes a first portion 361 and a second portion 362, wherein the first portion 361 is fixedly connected to the connecting plate 320, and the first portion 361 is perpendicular to the connecting plate 320, the second portion 362 is connected to an end of the first portion 361 away from the connecting plate 320, the second portion 362 extends toward the groove 110, and the second portion 362 is directly opposite to the portion between the two pressing blocks 310. When it is necessary to switch the pressure plate module 300 from the first station to the second station, the operator can pull up the second portion 362. Since the second portion 362 is suspended, the operator can easily act on the second portion 362, thereby pulling up the entire pressure plate module 300, which is convenient for operation.

[0038] In this embodiment, the connecting plate 320 can be connected to the jig bottom plate 100 through the hinge structure 400. When the pressing plate module 300 is switched to the second station, the pressing plate can be perpendicular to the bearing portion 120. At this time, the hinge structure 400 can ensure that the pressing block 310 and the jig bottom plate 100 remain relatively fixed. When the operator places the product 10 and the locking component 20 on the silicone mold 200, the pressing block 310 will not be displaced, ensuring the safety of the operator and the product 10.

[0039] In some embodiments, the material of the pressing block 310 is urethane foam. Specifically, the pressing block 310 can be made by 3D printing technology. Based on the characteristics of urethane foam, when the pressing block 310 is pressed on the locking component 20, the pressing block 310 has a certain deformation amount, and the pressing block 310 has a certain extrusion force on the locking component 20, thereby squeezing the locking component 20 to a fixed position, and in this process, the pressing block 310 will not scratch the locking component 20.

[0040] In this embodiment, if Figure 5 As shown, a stopper 330 is further provided on the side of each pressing block 310 away from the card slot 210, and the stopper 330 covers the surface of the side of the pressing block 310 away from the locking component 20. The material of the stopper 330 can be a rigid material, that is, a material that is not easily deformed. During the process of squeezing the pressing block 310 on the locking component 20, the stopper 330 can ensure that the pressing block 310 will not deform too much, thereby improving the positioning effect of the pressing block 310 on the locking component 20. Exemplarily, the material of the stopper 330 can be an aluminum alloy that has been anodized in its natural color.

[0041] In some embodiments, reference is made to Figure 1 , Figure 2 and Figure 7 , a magnet 340 may also be provided on one side of the pressing block 310 for pressing the locking component 20. When the pressing plate module 300 is in the first position, the magnet 340 may be directly opposite to the bearing portion 120 of the fixture base plate 100. Correspondingly, the bearing portion 120 may be provided with a magnetic attraction portion 130, and the magnet 340 and the magnetic attraction portion 130 attract each other, so that the pressing block 310 and the fixture base plate 100 can be quickly pre-positioned. Then, the locking component 20 and the product 10 are positioned by the pressing block 310. Thus, through multi-stage positioning, the positioning accuracy between the locking component 20 and the product 10 can be further improved, thereby ensuring the accuracy of the locking position and improving the quality of the product 10.

[0042] The number of magnetic attraction parts 130 may correspond to the number of magnets 340, that is, when each pressing block 310 is provided with a magnet 340, there are two magnetic attraction parts 130 corresponding to the pressing plate module 300, and when the pressing plate module 300 is in the first position, each magnetic attraction part 130 is directly opposite to the corresponding magnet 340, so as to ensure a good adsorption effect. Alternatively, the magnetic attraction part 130 may also be a whole piece, in which case the magnetic attraction part 130 is laid on the bearing part 120, so that when the pressing plate module 300 is in the first position, there is sufficient adsorption force between the magnetic attraction part 130 and the magnet 340, so as to ensure a good pre-positioning effect.

[0043] On this basis, continue to refer to Figure 5The pressing block 310 can be provided with locking holes 350 corresponding to the screw holes of the locking component 20. When the pressure plate module 300 is in the first station, each locking hole 350 of the pressing block 310 is directly opposite to the corresponding screw hole. After the positioning of the product 10 and the locking component 20 is completed by using the positioning fixture, the operator can use the locking tool to pass the screw through the locking hole 350 to complete the locking of the product 10 and the locking component 20. Due to the mutual attraction between the magnet 340 and the magnetic attraction part 130, during the process of locking the product 10 and the locking component 20, the pressing block 310 and the fixture bottom plate 100 remain relatively fixed, and the screws can be driven into the surface of the product 10, thereby avoiding scratches on the product 10.

[0044] The size of the locking hole 350 may be slightly larger than the size of the screw hole on the locking component 20 , so that the screw can pass through the locking hole 350 easily. In addition, the locking hole 350 may also limit the screw to prevent the screw from contacting the appearance surface of the product 10 .

[0045] In some embodiments, there may be two pressing plate modules 300, and the two pressing plate modules 300 may be respectively located on opposite sides of the groove 110, and each pressing plate module 300 may rotate relative to the fixture bottom plate 100. By providing two pressing plate modules 300, the two pressing plate modules 300 may be used to simultaneously press the locking components 20 at both ends of the product 10, and when the locking components 20 are subsequently locked to the product 10, the secondary positioning work may be omitted, thereby further improving the operating efficiency.

[0046] It is worth mentioning that when the product 10 is locked with only one locking component 20, one of the pressing plate modules 300 can be used to position the product 10 and the locking component 20, and when the product 10 is locked with two locking components 20, two pressing plate modules 300 can be used to simultaneously position the two locking components 20 and the product 10. In other words, the positioning fixture in this embodiment can be applied to multiple application scenarios and has a wider applicability.

[0047] Based on the same inventive concept, the embodiment of the present application may also provide a locking device, which may include an operating table, a locking tool, and a positioning fixture in any of the above embodiments, and both the locking tool and the positioning fixture may be placed on the operating table. After the positioning fixture is used to position the product 10 and the locking component 20, the locking tool may lock the locking component 20 and the product 10. The locking tool may be, for example, a manually operated screwdriver or an electric screwdriver.

[0048] In some embodiments, when the locking tool is an electric screwdriver, the locking device may further include a driving component, which may be used to drive the locking tool to move so that the locking tool can automatically complete the locking between the product 10 and the locking component 20. In this way, manual work can be saved, thereby further improving work efficiency.

[0049] In combination with the above embodiments, when the positioning fixture is used to lock the product 10 and the locking component 20 in the present application, the following steps can be referred to:

[0050] Step 1: Pull open the pressing plate module 300 so that the pressing block 310 rotates away from the fixture bottom plate 100 through the hinge structure 400;

[0051] Step 2: placing the product 10 in the slot 210 of the silicone mold 200 to position the product 10 through the silicone mold 200;

[0052] Step 3: Place the locking component 20 at the locking position of the product 10;

[0053] Step 4: Rotate the pressing plate module 300 to the first station, and quickly attract the magnet 340 on the pressing block 310 to the magnetic attraction portion 130 of the fixture bottom plate 100, thereby achieving pre-positioning between the pressing plate module 300 and the fixture bottom plate 100. In this process, when the pressing block 310 made of PU material contacts the locking component 20, based on the characteristics of PU, the locking component 20 can be quickly moved slightly, thereby achieving precise positioning;

[0054] Step 5: Place the positioning fixture on the operating table and start the locking operation;

[0055] Step 6: After the locking is completed, pull open the pressing plate module 300 and take out the locked product 10.

[0056] The positioning jig in this application can effectively prevent the product from being scratched by embedding a silicone mold that adapts to the shape of the product in the groove of the jig base plate. By providing a magnet, a magnetic suction part and a hinge structure, rapid pre-positioning between the pressure plate module and the jig base plate can be achieved. By using 3D printing technology to make a pressure block made of urethane material, the locking component and the product can be accurately positioned, thereby effectively absorbing the adverse effects caused by the position offset of the locking hole, ensuring the locking effect when the product is locked with the locking component, and thus improving the production line yield. During the locking process, the pressure plate module can always be pressed on the locking product, eliminating the manual pressing work of the operator and improving the operating efficiency.

[0057] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
