Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and more specifically, to a clamping device for multiple parts. Background Technology

[0002] With the development of modern industrial production, especially in the field of precision machinery manufacturing, higher requirements have been placed on the accuracy and efficiency of parts processing. In the machining process of various parts, fixtures, as an important auxiliary tool, can fix the parts in place during the machining process.

[0003] For example, patent CN222134165U discloses a machining fixture for mechanical parts. Although the fixture can increase its functionality and adaptability by replacing two clamping blocks with two sets of fixing screws when it needs to clamp mechanical parts of different sizes and shapes, in actual use, it only fixes the mechanical parts with two oppositely arranged clamping blocks and a pressing plate. This means that the fixture can only fix one section of the part. When the mechanical parts are large, the fixing effect is relatively poor, so it needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-part shared clamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-part shared clamping device includes a frame with multiple clamping assemblies movable along its length. Each clamping assembly includes an I-shaped bracket with a detachable support plate opposite to it. A movable relative clamping block is opposite to it on the bracket, and a liftable pressure plate is provided on the clamping block. The lifting and lowering of the pressure plate is used to press the parts tightly against the support plate. A first driving member is provided inside the bracket for driving the relative movement of the clamping blocks, and a second driving member is also provided on the bracket for driving them to move along the length of the frame.

[0007] Preferably, the bracket has a limiting groove along its length, and the clamping block can be moved within the limiting groove. The first driving member includes a rotatable lead screw mounted on the bracket. The lead screw is threaded through the clamping block, and the rotation of the lead screw drives the clamping block to move relative to it along its axial direction.

[0008] Preferably, the side wall of the clamping block is provided with a groove along its height direction, and the pressure plate is provided with a threaded post with one end extending out of the groove. A nut is threadedly connected to the threaded post, and turning the nut is used to keep the pressure plate in its current position.

[0009] Preferably, the bracket is equipped with a first motor for driving the lead screw to rotate.

[0010] Preferably, the frame has T-shaped grooves along its length on opposite side walls, and T-shaped blocks that slide within the T-shaped grooves are provided on the support.

[0011] Preferably, a rack is provided on one side of the frame, an extension plate is provided on one side of the bracket, and the second driving member includes a rotating shaft provided on the extension plate and rotatable, and a gear meshing with the rack is provided on the rotating shaft. The rotation of the gear is used to drive the bracket to move along the extension direction of the rack.

[0012] Preferably, a second motor for driving the shaft to rotate is provided on one side of the extension plate.

[0013] Preferably, a removable baffle is provided on the side of the frame near the rack.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the movable arrangement of the bracket on the frame, allows the position of adjacent brackets within the frame to be adjusted during actual use, so that adjacent clamping components can clamp and fix larger parts, resulting in better fixation.

[0016] This invention, through the setting of the baffle, isolates the rack and gear from the outside world, making it difficult for foreign objects to come into contact with the rack or gear, thus reducing the possibility of foreign objects affecting the rotation of the gear.

[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0032] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0033] Please see Figures 1-6 This embodiment of a multi-part shared clamping device includes a frame 100. The frame 100 is provided with a plurality of clamping assemblies that can move along its length. The clamping assemblies include an I-shaped bracket 600. A detachable support plate 120 is provided on the bracket 600. Specifically, the support plate 120 is connected to the bracket 600 by bolts. A clamping block 121 that can move relative to the support plate 120 is provided on the bracket 600. A lifting pressure plate 510 is provided on the clamping block 121. The lifting and lowering of the pressure plate 510 is used to press the parts onto the support plate 120. A first driving member is provided inside the bracket 600 for driving the clamping block 121 to move relative to the support plate 120. A second driving member is also provided on the bracket 600 for driving it to move along the length of the frame 100.

[0034] In this embodiment, when it is necessary to clamp and fix a flat part, first adjust the position of the bracket 600 on the frame 100 and fix it, place the part on the support plate 120, operate the first driving member to make the opposite clamping blocks 121 move closer to each other so that they abut against the opposite side wall of the part, and then move the pressure plate 510 down to contact the upper end surface of the support plate 120 to complete the fixing of the part.

[0035] The movable arrangement of the bracket 600 on the frame 100 allows for adjustment of the position of adjacent brackets 600 within the frame 100 during actual use, enabling adjacent clamping components to clamp and fix larger parts, resulting in better fixation. The frame 100 contains multiple sets of clamping components, allowing the clamping device to clamp multiple parts during actual use, increasing the number of parts it can clamp. This embodiment, through the above structure, enables the clamping device to clamp parts of different lengths, widths, and thicknesses, achieving the purpose of multiple parts sharing. Furthermore, the arrangement of multiple brackets 600, clamping blocks 121, and pressure plates 510 ensures that multiple positions of the parts can be fixed, thereby improving the fixation effect.

[0036] Specifically, when the support plate 120 is installed on the bracket 600, and the upper side of the support plate 120 is at the same level as the upper end of the frame 100, both sides of the part can be placed on the frame 100 when the part is fixed, so as to avoid the part being unstable due to the height difference between the frame 100 and the support plate 120.

[0037] Combination Figures 1-7 As shown, in this embodiment, a limiting groove 700 is provided in the bracket 600 along its length direction. The clamping block 121 can be moved within the limiting groove 700. The first driving member includes a lead screw 621 that is mounted on the bracket 600 and is rotatable. The lead screw 621 is rotatably mounted on the bracket 600 through a bearing. The lead screw 621 is threaded through the clamping block 121. The rotation of the lead screw 621 is used to drive the clamping block 121 to move relative to it along its axial direction.

[0038] In this embodiment, since the sidewall of the clamping block 121 slides against the sidewall of the support plate 120, and the lead screw 621 is threaded through the clamping block 121, and the lead screw 621 is provided with symmetrical and opposite threads, which are used to connect with the corresponding clamping block 121, when the lead screw 621 rotates, the clamping blocks 121 located on it will move closer or further away from each other. When the clamping blocks 121 move closer to each other, the part can be fixed, and when the clamping blocks 121 move further away from each other, the part can be released from the fixation.

[0039] Specifically, a first motor 620 is detachably connected to the side wall of the bracket 600 by screws. The output shaft of the first motor 620 is fixedly connected to one end of the lead screw 621. When the first motor 620 is started, it can drive the lead screw 621 to rotate, thereby realizing the relative movement of the clamping block 121.

[0040] Combination Figures 1-5As shown, in this embodiment, a sliding groove 501 is provided on the side wall of the clamping block 121 along its height direction. A threaded post 512 with one end extending out of the sliding groove 501 is fixedly connected to the pressure plate 510. A nut 513 is threadedly connected to the threaded post 512. Tightening the nut 513 is used to keep the pressure plate 510 in its current position.

[0041] In this embodiment, the pressure plate 510 is L-shaped. When it is necessary to adjust the distance between the pressure plate 510 and the support plate 120, the nut 513 can be turned to disengage it from the side wall of the clamping block 121. Then, the pressure plate 510 is moved along the slide groove 501 to bring it closer to the support plate 120. Finally, the nut 513 is tightened to fix the pressure plate 510, thereby fixing the upper end face of the part.

[0042] Specifically, in order to prevent the threaded post 512 from rotating within the slide groove 501 when the pressure plate 510 moves, thus affecting the pressure plate 510's ability to press the upper surface of the part, in this embodiment, a limiting post 511 is fixedly connected to the pressure plate 510. Both the limiting post 511 and the threaded post 512 slide within the slide groove 501, and their sidewalls abut against the sidewall of the slide groove 501, thereby preventing the pressure plate 510 from rotating during lifting and lowering.

[0043] Combination Figures 1-6 As shown, in this embodiment, a T-shaped groove 400 is provided along the length direction of the opposite side wall of the frame 100, and a T-shaped block 610 that slides in the T-shaped groove 400 is fixedly connected to the bracket 600.

[0044] In this embodiment, the T-shaped block 610 and the T-shaped groove 400 are configured to restrict the movement of the support 600 on the frame 100, that is, it can only move along the extension direction of the T-shaped groove 400.

[0045] Combination Figures 1-6 As shown, in this embodiment, a rack 300 is fixedly connected to one side of the frame 100, and an extension plate 310 is fixedly connected to one side of the bracket 600. The second driving component includes a rotating shaft disposed on the extension plate 310 and rotatable. Specifically, the rotating shaft is rotatably connected to the extension plate 310 through a bearing, and a gear 312 that meshes with the rack 300 is fixedly connected to the rotating shaft. The rotation of the gear 312 is used to drive the bracket 600 to move along the extension direction of the rack 300.

[0046] In this embodiment, when the rotating shaft rotates, it can drive the gear 312 to rotate. Since the rack 300 and the frame 100 are relatively fixed in position, and the gear 312 meshes with the rack 300, the gear 312 will move along the direction of the rack 300, thereby driving the bracket 600 to move on the frame 100 so that it can adapt to parts of different lengths.

[0047] One side of the extension plate 310 is detachably connected to a second motor 311 by screws. The output shaft of the second motor 311 is fixedly connected to the rotating shaft. When it is necessary to drive the rotating shaft to rotate, the second motor 311 can be started.

[0048] In practical use, both the second motor 311 and the first motor 620 are servo motors with self-locking function. The output ends of the second motor 311 and the first motor 620 are fixedly connected to a reducer, which can control the rotation speed of the output shafts of the second motor 311 and the first motor 620, making their operation more stable.

[0049] Among them, a detachable baffle 101 is connected to the side of the frame 100 near the rack 300 by countersunk screws. The baffle 101 isolates the rack 300 and gear 312 from the outside world, making it difficult for foreign objects to come into contact with the rack 300 or gear 312, thereby reducing the possibility of foreign objects affecting the rotation of gear 312.

[0050] Combination Figures 1-6 As shown, in this embodiment, a side plate 110 is detachably connected to the opposite side wall of the frame 100 by screws, and a support leg 111 is fixedly connected to the side plate 110.

[0051] In this embodiment, the side plate 110 can block the opening of the T-slot 400, thereby preventing the bracket 600 from coming out of the opening of the T-slot 400 when it moves. The support leg 111 is fixedly connected to the upper end face of the machine tool (not shown in the figure) by screws, thereby fixing the clamping device on the machine tool. In actual use, a grinding device is fixedly connected to the machine tool. The grinding device can grind the parts fixed on the clamping device, thereby realizing the processing of the parts.

[0052] In this embodiment, when it is necessary to clamp and fix a flat part, the second motor 311 first drives the rotating shaft and gear 312 to rotate, so that the bracket 600 moves along the T-slot 400 on the frame 100. When it moves to the required position, the part is placed on the upper surface of the frame 100 and the support plate 120. Then, the first motor 620 drives the lead screw 621 to rotate, so that the clamping blocks 121 located on it move closer to each other to fix the side wall of the part. Then, the nut 513 is turned away from the side wall of the clamping block 121. Then, the pressure plate 510 is moved along the slide groove 501 so that the pressure plate 510 overlaps the upper surface of the part. Finally, the nut 513 is tightened to fix the upper surface of the part.

[0053] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
