Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thin-walled piece processing, in particular to a thin-walled piece clamping tool. Background Art
[0002] Thin-walled parts typically refer to structural components that are designed to be thinner and are typically lightweight. Due to their thin walls, they are particularly popular in aerospace, automotive, medical device, and other fields. However, when processing thin-walled parts, special attention must be paid to dimensional accuracy and deformation control during processing. This is because even slight dimensional differences and deformation in thin-walled parts can lead to assembly difficulties or poor performance. Furthermore, due to their thin walls, they are prone to deformation and even damage during processing. This is especially true during machining processes such as cutting and grinding, which require specialized techniques and tools. During assembly, special attention must be paid to alignment and fixing, as otherwise, deformation due to pressure can easily occur, affecting the overall accuracy and strength of the product.
[0003] Thin-walled part clamping fixtures are designed to ensure the stability of thin-walled parts during machining. Thin-walled parts are prone to deformation during clamping, so the clamping fixture must be designed to evenly distribute the clamping force and minimize deformation. During machining, thin-walled parts must maintain precise positioning, ensuring accurate positioning and securement to enhance machining stability and safety. Clamping fixtures must be able to accommodate thin-walled parts of varying shapes, sizes, and types, and sometimes multiple thin-walled parts must be clamped and processed.
[0004] In the process of realizing the present invention, the inventors discovered that the prior art had the following problems: 1. When processing thin-walled parts, the existing clamping tools require the operator to manually flip the thin-walled parts, thereby changing the processing position of the thin-walled parts, which has low production efficiency and high labor intensity; 2. When processing thin-walled parts, the existing clamping tools often ignore the clamping of the hollow interior, which easily causes the thin-walled parts to deform when using external clamps, thereby reducing the production quality of thin-walled products. Utility Model Content

The existing clamping tool requires the operator to manually flip the thin-walled workpiece when processing the thin-walled workpiece, thereby changing the processing position of the thin-walled workpiece, which has low production efficiency and high labor intensity. In addition, the existing clamping tool often ignores the clamping of the hollow interior of the thin-walled workpiece when processing the thin-walled workpiece, which easily causes the thin-walled workpiece to deform when using an external clamp, thereby reducing the production quality of the thin-walled workpiece product. To achieve the above purpose, the present invention provides the following technical solution: a thin-walled workpiece clamping tool, comprising a base, a support plate welded to one side of the top of the base, a fixing groove welded to one side of the outer wall of the support plate, the inner part of the fixing groove is clamped to a drive motor, the output end of the drive motor is plugged into a connecting shaft, the other end of the connecting shaft is welded to a turntable, the turntable is provided with an inner clamping mechanism on the side away from the drive motor, the outer wall of the turntable is slidably connected to a slide seat, the other side of the top of the base is welded to a fixing plate, the inner part of the fixing plate is horizontally penetrated by the outer clamping mechanism.
[0006] Further preferably, the driving motor, the connecting shaft and the turntable together constitute a rotating mechanism.
[0007] Further preferably, a supporting slide groove is provided on the top of the base directly below the connecting shaft, and the supporting slide groove forms a sliding connection with the connecting shaft.
[0008] Further preferably, the annular inner wall of the slide seat is provided with a slide rail, and the slide rail is in sliding connection with the turntable.
[0009] Further preferably, the internal clamping mechanism consists of an insertion rod, an electric telescopic rod and a silicone pad, wherein one end of the insertion rod is welded to the outer wall of one side of the turntable, the electric telescopic rod is inserted into the inside of the insertion rod and is distributed in an umbrella shape, and the silicone pad is arranged at the driving end of the electric telescopic rod.
[0010] Further preferably, the external clamping mechanism consists of a hydraulic push rod, a connecting rod, a splint and a rubber layer, wherein the driving end of the hydraulic push rod passes horizontally through the interior of the fixed plate, the convex side of the connecting rod is arranged at the driving end of the hydraulic push rod, the end of the connecting rod is welded to one side of the splint, and the rubber layer is bonded to the other side of the splint.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] In the utility model, the driving motor is started to drive the connecting shaft plugged therein to start rotating, thereby automatically rotating the turntable and the entire internal clamping mechanism and thin-walled workpiece arranged on the other side of the turntable, so that all parts of the outer wall of the thin-walled workpiece can be subjected to contact processing from the processing tool, thereby completing the processing operation of the entire thin-walled workpiece. At the same time, the self-rotating thin-walled workpiece can also avoid the operator from manually changing the position of the thin-walled workpiece, thereby improving production efficiency and reducing the labor intensity of the operator.
[0013] In the present invention, a thin-walled part is sleeved on the outside of the insertion rod, and then a plurality of electric telescopic rods are started simultaneously through an external controller to push the driving end thereof toward the outside until the silicone cushion provided at the driving end thereof fits against the inner wall of the thin-walled part, so that the two are in contact with each other, thereby completing the clamping and fixation of the inside of the thin-walled part, and providing it with an inner supporting force to avoid deformation of the thin-walled part during the process of completing the outer clamping. Then, the hydraulic push rod is started, and the left and right side splints are pushed toward the middle thin-walled part through the connecting rod until the rubber layer provided on the opposite side of the splint can fit tightly against the outer wall of the thin-walled part, thereby realizing external clamping of the thin-walled part. The double internal and external clamping can effectively prevent the thin-walled part from being deflected in position due to the influence of external factors during the processing, thereby improving the processing quality of the product and the stable operation of the processing operation.

[0019] 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 embodiments described 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 technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0020] See also Figures 1 to 4 The utility model provides a technical solution: a thin-walled part clamping tool, including a base 1, a support plate 2 is welded to one side of the top of the base 1, a fixing groove 3 is welded to the outer wall of one side of the support plate 2, the inside of the fixing groove 3 is clamped to the driving motor 4, the output end of the driving motor 4 is plugged with a connecting shaft 5, the other end of the connecting shaft 5 is welded to a turntable 6, an internal clamping mechanism 7 is provided on the side of the turntable 6 away from the driving motor 4, a slide seat 8 is slidably connected to the outer wall of the turntable 6, a fixing plate 9 is welded to the other side of the top of the base 1, and an external clamping mechanism 10 is horizontally penetrated inside the fixing plate 9.
[0021] In this embodiment, Figure 1 and Figure 2 As shown, the drive motor 4, the connecting shaft 5 and the turntable 6 together constitute a rotating mechanism; it should be noted that, in actual application, the operator can first put the thin-walled part on the outside of the insertion rod 701 of the inner clamping mechanism 7. After being doubly clamped by the inner clamping mechanism 7 and the outer clamping mechanism 10, the drive motor 4 can be started to drive the connecting shaft 5 plugged therein to start rotating, thereby automatically rotating the turntable 6 and the entire inner clamping mechanism 7 and the thin-walled part on the other side of the turntable 6, so that all parts of the outer wall of the thin-walled part can be processed by the processing tool, thereby completing the processing operation of the entire thin-walled part. At the same time, the self-rotating thin-walled part can also save the operator from manually changing the position of the thin-walled part, thereby improving production efficiency and reducing the labor intensity of the operator.
[0022] In this embodiment, Figure 1 and Figure 2As shown, a supporting slot 101 is provided at the top of the base 1 just below the connecting shaft 5, and the supporting slot 101 is slidably connected to the connecting shaft 5; it should be noted that when the operator starts the drive motor 4 to drive the connecting shaft 5 and the turntable 6 connected thereto to rotate, the connecting shaft 5 provided between the connecting shaft drive motor 4 and the turntable 6 plays a joint role. During the rotation process, it will bear the weight from the left and right side components and its own weight, so it is easy to shake due to mechanical vibration, and it is also easy to be damaged due to insufficient bearing force. Therefore, in the present utility model, a supporting slot 101 is provided at the bottom of the connecting shaft 5 to form a sliding connection therewith. During the rotation process, the connecting shaft 5 will rotate in contact with the annular inner wall of the supporting slot 101. At the same time, the supporting slot 101 welded to the top of the base 1 can also provide an upward supporting force for the entire connecting shaft 5, thereby ensuring the stable operation of the connecting shaft 5 during the rotation process, and can also bear part of the gravity borne by the connecting shaft 5, thereby reducing the probability of damage to the connecting shaft 5 and extending its service life.
[0023] In this embodiment, Figure 3 As shown, the annular inner wall of the slide 8 is provided with a slide rail 801, and the slide rail 801 is slidably connected to the turntable 6; it should be noted that when the driving motor 4 is started to drive the connected rotating shaft 5 and the turntable 6 to rotate, the turntable 6 will drive the internal clamping mechanism 7 and the thin-walled part provided on its outer wall to rotate, so the turntable 6 set in the air will be extremely unstable during the rotation process, thereby affecting the processing operation of the thin-walled part. Therefore, in the present utility model, a slide 8 is provided directly below the turntable 6, and a slide rail 801 is provided on the annular inner wall of the slide 8, and is slidably connected to the turntable 6. When the turntable 6 is rotated by the driving motor 4 and the connecting rotating shaft 5, the annular outer wall of the turntable 6 will rotate in contact with the inner wall of the slide rail 801, thereby limiting the stability of the entire turntable 6 during rotation, preventing it from positional displacement due to mechanical vibration, and avoiding affecting the relative position between the thin-walled part and the processing tool, thereby affecting the entire processing operation, thereby improving the production quality of the product.
[0024] In this embodiment, Figure 3As shown, the inner clamping mechanism 7 is composed of an insertion rod 701, an electric telescopic rod 702 and a silicone soft pad 703, wherein one end of the insertion rod 701 is welded to the outer wall of one side of the turntable 6, and the electric telescopic rod 702 is inserted into the interior of the insertion rod 701 and is distributed in an umbrella shape. The silicone soft pad 703 is provided at the driving end of the electric telescopic rod 702; It should be noted that in the clamping operation of a general thin-walled part, only the outer wall is often clamped and fixed, and the support of the hollow interior is ignored. Therefore, an inner The clamping mechanism 7 is achieved by sleeve-mounting the thin-walled part on the outside of the insertion rod 701, and then simultaneously starting several electric telescopic rods 702 through an external controller, so that the driving end thereof is pushed outward until the silicone cushion 703 provided on the driving end thereof is in contact with the inner wall of the thin-walled part, so that the two are in contact with each other, thereby completing the clamping and fixing of the inside of the thin-walled part and providing it with an inner support force, thereby avoiding deformation of the thin-walled part during the process of completing the outer clamping, and further improving the processing quality and the stability of the clamping.
[0025] In this embodiment, Figure 4 As shown, the outer clamping mechanism 10 is composed of a hydraulic push rod 1001, a connecting rod 1002, a clamping plate 1003 and a rubber layer 1004, wherein the driving end of the hydraulic push rod 1001 transversely passes through the interior of the fixed plate 9, the convex side of the connecting rod 1002 is arranged at the driving end of the hydraulic push rod 1001, the end of the connecting rod 1002 is welded to one side of the clamping plate 1003, and the rubber layer 1004 is bonded to the other side of the clamping plate 1003; it should be noted that, during the process of the operator processing the thin-walled parts, due to mechanical vibration or human touch, it is easy to cause the thin-walled parts to deviate or rotate during the processing, thereby affecting the processing quality of the product. Therefore, in the present invention, an external clamping mechanism 10 is designed. After the inner clamping of the thin-walled part is completed by the internal clamping mechanism 7, the operator can start the hydraulic push rod 1001 and push the left and right side clamps 1003 toward the middle thin-walled part through the connecting rod 1002 until the rubber layer 1004 on the opposite side of the clamp 1003 can fit tightly against the outer wall of the thin-walled part, thereby realizing external clamping of the thin-walled part and limiting its position, thereby effectively preventing the thin-walled part from being deflected in position due to the influence of external factors during the processing, thereby improving the processing quality of the product and the stable operation of the processing operation.
[0026] The use method and advantages of the utility model: When the thin-walled part clamping tool is used, the working process is as follows:
[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, first, the thin-walled part is sleeved on the outside of the insertion rod 701, and then a plurality of electric telescopic rods 702 are started at the same time through an external controller, so that the driving ends thereof extend outward until the silicone soft pad 703 provided at the driving ends thereof is pushed to fit the inner wall of the thin-walled part, so that the two are in contact with each other, thereby completing the clamping and fixing of the inside of the thin-walled part, and then the hydraulic push rods 1001 on the left and right sides are started at the same time, so that the driving ends of the two push the connecting rod 1002 and the splint 1003 provided at the end of the connecting rod 1002 toward the middle thin-walled part, until the silicone soft pad 703 provided at the driving end thereof is pushed to fit the inner wall of the thin-walled part, so that the silicone soft pad 703 provided at the driving end thereof is in contact with the inner wall of the thin-walled part, thereby completing the clamping and fixing of the inside of the thin-walled part, and then the hydraulic push rods 1001 on the left and right sides are started at the same time, so that the driving ends of the two push the connecting rod 1002 and the splint 1003 provided at the end of the connecting rod 1002 toward the middle thin-walled part, until the silicone soft pad 703 provided at the driving end thereof is pushed to fit the inner wall of the thin-walled part, The rubber layer 1004 on the opposite side of the splint 1003 can fit tightly against the outer wall of the thin-walled part, thereby completing the external clamping of the thin-walled part. At the same time, the operator can start the drive motor 4 to rotate its output end and drive the connecting shaft 5 connected to it to rotate, thereby causing the turntable 6 at the other end of the connecting shaft 5 and the thin-walled part clamped on the other side of the turntable 6 to rotate together. During this period, the operator can use various processing tools to perform specific processing on various parts of the outer wall of the thin-walled part, thereby realizing the processing operation of an entire thin-walled part.
