[0001] The utility model relates to the technical field of jigs, and in particular to a positioning clamping device and a turntable jig. Background Art

[0002] When using some turntable jigs, the product is often placed on the upper surface of the jig. This method makes it easy for the product to shift or even fall due to rotational inertia as the product rotates with the turntable, resulting in the need to reposition the product before proceeding to the next process, which not only wastes time but also is costly.

[0037] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0038] Figure 1 A schematic diagram of the structure of the positioning and clamping device 010 provided in this embodiment when it is in an open clamping state; Figure 2 A schematic diagram of the structure of the positioning and clamping device 010 provided in this embodiment when it is in a closed clamping state;

[0039] Figure 3 An exploded view of the structure of the positioning and clamping device 010 provided in this embodiment; Figure 4 FIG. 1 is a top view of the positioning and clamping device 010 provided in this embodiment. Figures 1 to 4 As shown, this embodiment provides a positioning clamping device 010, including a fixed seat 100, a movable seat 200, a first pressing piece 300 and a second pressing piece 400, wherein the fixed seat 100 and the movable seat 200 are arranged at intervals along a first direction, the movable seat 200 is movably mounted on the fixed seat 100 along the first direction, and a bearing surface 131 is provided on a side of the fixed seat 100 away from the movable seat 200; the first pressing piece 300 is rotatably mounted on the fixed seat 100, and the rotation axis of the first pressing piece 300 extends along a second direction perpendicular to the first direction, and the movable seat 200 is rotatably mounted on the fixed seat 100. The seat 200 is transmission connected with the first pressing piece 300, and the second pressing piece 400 is movably arranged on the fixed seat 100 along the second direction. The movable seat 200 is transmission connected with the second pressing piece 400, and the movement of the movable seat 200 is used to drive the first pressing piece 300 to rotate and the second pressing piece 400 to move, so that the first pressing piece 300 and the second pressing piece 400 are close to the bearing surface 131 at the same time or away from the bearing surface 131 at the same time; the fixed seat 100 is provided with a limiting portion 110, and the limiting portion 110 and the second pressing piece 400 are respectively arranged on both sides of the bearing surface 131 along the second direction.

[0040] It should be noted that, in this embodiment, the first direction can be Figure 1 and Figure 2 The second direction can be represented by the direction indicated by the arrow ab in Figure 1 and Figure 2 The third direction that appears below can be represented by the direction indicated by the arrow cd in Figure 1 and Figure 2 It is indicated by the direction indicated by the arrow ef.

[0041] When the positioning and clamping device 010 is used, the product is placed on the bearing surface 131 of the fixed seat 100, and the fixed seat 100 carries the product; then, the movable seat 200 moves along the first direction, and under the action of the transmission connection between the movable seat 200 and the first pressing piece 300 and the second pressing piece 400, the first pressing piece 300 is driven to rotate close to the bearing surface 131, and the second pressing piece 400 is driven to move close to the bearing surface 131. When the second pressing piece 400 approaches the bearing surface 131, a thrust along the second direction is applied to the product, and under the limiting action of the limiting part 110, the product is limited to the space between the second pressing piece 400 and the limiting part 110, so as to achieve the positioning of the product; when the first pressing piece 300 approaches the bearing surface 131, a pressing force is applied to the product, so as to fix the product in the space between the second pressing piece 400 and the limiting part 110, so as to achieve the clamping of the positioned product.

[0042] It can be seen that the positioning and clamping device 010, through the above-mentioned arrangement, can apply force to the product from different directions during the movement of the movable seat 200, so as to simultaneously complete the positioning and clamping operations of the product. In other words, only a driving member for moving the movable seat 200 along a first direction is required to complete the two actions of positioning and clamping. The number of driving members is small, thereby effectively solving the technical problem of the large number of driving members of the turntable fixture used to apply force to the product in multiple directions in the prior art.

[0043] In addition, this arrangement of the positioning clamping device 010 can also reduce the movements and parts at the top as much as possible, thereby reserving sufficient space for other mechanisms and manual operations.

[0044] Please continue to refer to Figure 3 In this embodiment, the first pressure piece 300 may include a rotating part 310 and a pressure rod part 320, the movable seat 200 includes a movable plate 210 and a driving rack 220 fixedly connected to the movable plate 210, the driving rack 220 extends along the first direction, wherein the pressure rod part 320 is used to approach or move away from the bearing surface 131; the rotating part 310 is rotatably connected to the fixed seat 100, and the outer surface of the rotating part 310 is provided with a toothed structure 311, and the driving rack 220 cooperates with the toothed structure 311 for driving the rotating part 310 to rotate.

[0045] When the first pressure rod is needed to press the product placed on the bearing surface 131, the movable plate 210 of the movable seat 200 moves along the first direction, driving the driving rack 220 to move along the first direction, and the driving rack 220 and the toothed structure 311 of the rotating part 310 of the first pressure piece 300 are used to rotate the rotating part 310, so that the pressure rod part 320 can swing toward the direction close to the bearing surface 131 to press the product on the bearing surface 131. When the product needs to be taken out, the movable plate 210 of the movable seat 200 will move in the opposite direction, and the driving rack 220 and the toothed structure 311 of the rotating part 310 are used to rotate the rotating part 310 in the opposite direction, so that the pressure rod part 320 can swing toward the direction away from the bearing surface 131 to release the pressing effect on the product.

[0046] This form of driving the first pressure rod by utilizing the cooperation between the driving rack 220 and the toothed structure 311 has a smooth transmission, and the opening and closing processes are stable without generating abnormal noise.

[0047] Please continue to refer to Figure 3In this embodiment, the positioning and clamping device 010 may also include a transmission gear 500. Specifically, the transmission gear 500 is rotatably installed on the fixed seat 100. The transmission gear 500 is meshed and connected to the driving rack 220 and the toothed structure 311. The transmission gear 500 is configured to move the pressure rod portion 320 away from the bearing surface 131 when the movable seat 200 is close to the fixed seat 100.

[0048] Please continue to refer to Figure 3 In this embodiment, when the movable seat 200 approaches the fixed seat 100 along the first direction, that is, when the driving rack 220 moves upward, it will drive the transmission gear 500 to move in the counterclockwise direction ( Figure 3 The first pressing member 300 is rotated in the current viewing angle, thereby realizing the purpose of moving the first pressing member 300 away from the bearing surface 131, realizing the clamping and releasing the product; similarly, when the movable seat 200 moves away from the fixed seat 100 along the first direction, that is, when the driving rack 220 moves downward, it will drive the transmission gear 500 to move in the clockwise direction ( Figure 3 The current viewing angle) rotates, thereby achieving the purpose of moving the first pressing member 300 toward the direction close to the bearing surface 131, thereby closing the clamp and clamping the product.

[0049] The arrangement of the transmission gear 500 not only changes the transmission direction from the driving rack 220 to the first pressing member 300 , but also optimizes the transmission path from the driving rack 220 to the first pressing member 300 .

[0050] Please continue to refer to Figures 1 to 3 In this embodiment, the fixed base 100 includes a fixed plate 120 and a product placement block 130 fixedly arranged on the fixed plate 120, wherein the fixed plate 120 is provided with an opening 121, and the rotating part 310 is rotatably installed on a group of side walls opposite to the opening 121 along the second direction; the bearing surface 131 is placed on the product placement block 130.

[0051] The setting of the product placement block 130 can better match the appearance of the product, thereby achieving effective support for multiple areas of the product and ensuring the stability of the product placed on the fixing seat 100.

[0052] Please continue to refer to Figures 1 to 3 In this embodiment, the rotating part 310 of the first pressure piece 300 is rotatably mounted on the fixed base 100 through the first shaft 160, and the transmission gear 500 is rotatably mounted on the fixed base 100 through the second shaft 170. Specifically, the rotating part 310 of the first pressure piece 300 is rotatably mounted on the fixed plate 120 through the first shaft 160, and a connecting frame 150 is fixedly provided at the bottom of the fixed plate 120, and the transmission gear 500 is rotatably mounted on the connecting frame 150 through the second shaft 170.

[0053] Figure 5 for Figure 4Please continue to refer to the AA section view in Figure 3 , and combined with Figure 5 In this embodiment, the movable seat 200 may also include a push rod 230 fixedly connected to the movable plate 210, and a driving inclined surface 231 is provided at the position of the push rod 230 facing the second pressure piece 400, and a transmission inclined surface 410 is provided at the position of the second pressure piece 400 facing the push rod 230, wherein the driving inclined surface 231 and the transmission inclined surface 410 are matched in transmission to drive the second pressure piece 400 to move.

[0054] When the second pressure piece 400 needs to be moved closer to or away from the bearing surface 131, the movable plate 210 moves along the first direction, driving the push rod 230 to move along the first direction. In the process of the push rod 230 moving along the first direction, the driving inclined surface 231 provided on the push rod 230 will cooperate with the transmission inclined surface 410 provided on the second pressure piece 400, thereby realizing the driving of the second pressure piece 400.

[0055] This form of driving the second pressing piece 400 by using the cooperation between the driving inclined surface 231 and the transmission inclined surface 410 is not only reliable in driving, but also can save space, which is conducive to further reducing the overall size of the positioning clamping device 010.

[0056] Please continue to refer to Figure 5 In this embodiment, the driving inclined surface 231 is arranged on the side of the push rod 230 away from the bearing surface 131, and from the movable plate 210 to the fixed plate 120, the driving inclined surface 231 extends obliquely in the direction close to the bearing surface 131, and the transmission inclined surface 410 is in contact with the driving inclined surface 231; the positioning and clamping device 010 also includes a first compression spring 600, which is arranged between the second pressing piece 400 and the fixed seat 100, and is used to make the second pressing piece 400 always have a movement tendency close to the bearing surface 131.

[0057] by Figure 5Taking the perspective shown in the figure as an example, when the second pressing member 400 needs to switch from the closing position to the opening position, that is, when the second pressing member 400 needs to move away from the bearing surface 131, the movable plate 210 rises, driving the push rod 230 to rise. During the rising process of the push rod 230, the driving inclined surface 231 will slide relative to the transmission inclined surface 410, thereby driving the second pressing member 400 to move in the direction away from the bearing surface 131. In this process, the first compression spring 600 is compressed to store elastic potential energy. When the second pressing piece 400 moves to approach the bearing surface 131 to realize the positioning and clamping operation of the product, the movable plate 210 descends, driving the push rod 230 to descend. During the descending process of the push rod 230, the driving inclined surface 231 will gradually cooperate with the transmission inclined surface 410 from the narrower part at the upper end, providing space for the second pressing piece 400 to move to the right. At the same time, under the action of the elastic potential energy stored in the first compression spring 600, the second pressing piece 400 will be driven to move toward the bearing surface 131 to position and clamp the product.

[0058] This form of driving the second pressing member 400 enables the second pressing member 400 to always have a movement tendency close to the bearing surface 131, thereby ensuring the reliability of positioning and clamping the product after the movable plate 210 descends.

[0059] Please continue to refer to Figure 3 and Figure 5 In this embodiment, the fixing seat 100 further includes a mounting block 140 fixedly connected to the fixing plate 120, wherein the second pressing member 400 is movably mounted on the mounting block 140 along the second direction.

[0060] Please continue to refer to Figure 5 In this embodiment, a receiving hole 420 is provided on a side of the second pressing member 400 away from the bearing surface 131, and the first compression spring 600 is installed in the receiving hole 420. The provision of the receiving hole 420, on the one hand, can realize the installation and accommodation of the first compression spring 600, reducing the risk of the first compression spring 600 falling off, and on the other hand, can also guide the extension and retraction process of the first compression spring 600, preventing the first compression spring 600 from bending.

[0061] Please continue to refer to Figure 3 In this embodiment, the number of the second pressure members 400 is two, and the two second pressure members 400 are arranged at intervals along the third direction, and the third direction is perpendicular to both the first direction and the second direction. The number of the push rods 230 is the same as the number of the second pressure members 400, which is also two, and the two push rods 230 are respectively arranged in a one-to-one correspondence with the two second pressure members 400.

[0062] This arrangement of the second pressing piece 400, on the one hand, enables multi-point support to be provided to the product when force is applied to the product on the bearing surface 131 to prevent the product from deflecting; on the other hand, it also ensures uniform distribution of the clamping force on the product to avoid stress concentration on the product.

[0063] In other embodiments, the number of the second pressing members 400 may also be three or four.

[0064] Please continue to refer to Figures 1 to 3 ,as well as Figure 5 In this embodiment, the movable seat 200 is movably mounted on the fixed seat 100 through the guide assembly 700. The guide assembly 700 includes a guide rod 710 and a second compression spring 720, wherein the guide rod 710 includes a limiting section 711 and a guide section 712 arranged in sequence along the length direction, and the movable plate 210 is provided with a guide hole 211 that slidably cooperates with the guide section 712. The guide section 712 is penetrated through the guide hole 211 and fixedly connected to the fixed seat 100. The limiting section 711 is located on the side of the movable seat 200 away from the fixed seat 100, and is used to limit the maximum stroke of the movable seat 200 in the direction away from the fixed seat 100; the second compression spring 720 is sleeved on the guide section 712, and one end of the second compression spring 720 abuts against the fixed seat 100, and the other end of the second compression spring 720 abuts against the movable seat 200.

[0065] When the positioning and clamping device 010 is in the initial state, under the action of the second compression spring 720, the movable plate 210 moves away from the fixed plate 120, so that the first pressure piece 300 and the second pressure piece 400 press the product; when the clamp needs to be opened, the movable plate 210 approaches the fixed plate 120. At this time, the guide hole 211 of the movable plate 210 slides with the guide rod 710 of the guide assembly 700 to guide the movement of the movable plate 210. At the same time, the second compression spring 720 is compressed, and the push rod 230 cooperates with the transmission inclined surface 410 of the second pressure piece 400 through the driving inclined surface 231, so that the second pressure piece 400 moves in a direction away from the bearing surface 131 and compresses the first compression spring 600 to achieve clamping; after taking out the product, the movable plate 210 moves away from the fixed plate 120 under the action of the second compression spring 720, so that the first pressure piece 300 and the second pressure piece 400 move in a direction close to the bearing surface 131 and return to the initial position.

[0066] This form of connecting the movable plate 210 and the fixed plate 120 using the guide assembly 700 can not only enable the movable plate 210 to be movably installed on the fixed plate 120 along the first direction, but also realize the guidance of the movable plate 210 during movement, and this setting can make the movable plate 210 automatically reset.

[0067] Please continue to refer to Figures 1 to 3In this embodiment, a plurality of guide assemblies 700 are provided, and the plurality of guide assemblies 700 are arranged at intervals. The movable plate 210 is provided with a plurality of guide holes 211, and the number of the guide holes 211 is the same as the number of the guide assemblies 700. The guide rods 710 of the plurality of guide assemblies 700 are respectively and correspondingly penetrated through the plurality of guide holes 211.
