Description

Technical Field

[0001] This utility model relates to the field of jig technology, specifically a rotatable jig. Background Technology

[0002] In fields such as machining and electronic component testing, fixtures are key tooling to ensure the machining accuracy and testing precision of workpieces. Their core function is to stably clamp the workpiece and assist in adjusting the workpiece angle to adapt to the needs of multi-process and multi-face operation. For example, scenarios such as drilling holes on multiple sides of a cuboid workpiece and full-angle dimensional inspection of irregularly shaped parts all rely on the function of fixtures.

[0003] The existing fixtures still have the following problems: general fixtures are fixed structures, which can clamp the workpiece but cannot directly adjust the angle. Each time a face-changing operation is required, the workpiece must be disassembled and repositioned and clamped, which is not only time-consuming and labor-intensive, but also prone to cumulative errors due to repeated positioning, resulting in a decrease in workpiece accuracy.

[0004] Therefore, there is an urgent need for a rotatable fixture to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a rotatable fixture to solve the problem of rotatable fixtures.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A rotatable jig, comprising:

[0008] Chassis;

[0009] A fixing plate is disposed above the chassis. The upper end of the fixing plate is used to install a clamping body, which is used to clamp the workpiece. The fixing plate is rotatably mounted on the chassis about an axis perpendicular to the upper surface of the chassis via a rotating assembly.

[0010] The rotating assembly includes a toothed body, a mating toothed body, and a connecting rod. The toothed body is fixed to the lower end face of the fixed plate, and the mating toothed body is fixed to one end of the connecting rod. One end of the connecting rod is rotatably inserted through the chassis and extends into the chassis. The mating toothed body extends into the chassis along with the connecting rod and meshes with the toothed body. The other end of the connecting rod is located outside the chassis to provide rotational driving force. By driving the connecting rod to rotate, the mating toothed body can be driven to rotate, thereby driving the toothed body and the fixed plate connected to it to rotate around the chassis.

[0011] As a preferred embodiment of a rotatable fixture, both the toothed body and the mating toothed body are bevel gears, and their axes intersect perpendicularly. The mating toothed body engages with the beveled toothed body through a beveled tooth surface to achieve the reversal transmission of the rotational motion of the connecting rod to the rotational motion of the fixed plate.

[0012] As a preferred embodiment of a rotatable fixture, the top surface of the chassis is provided with a groove, the opening of which faces the fixed plate, and its internal space is used to provide clearance space for the rotation of the toothed body, the meshing motion of the mating toothed body and the end movement of the connecting rod.

[0013] As a preferred embodiment of a rotatable fixture, the clamping body includes a mounting plate, a rotating rod, a reference plate, and a clamping plate. The mounting plate is fixedly connected to the fixed plate, and a groove is formed on the top surface of the mounting plate in a horizontal direction. The reference plate is vertically fixed to one side of the top surface of the mounting plate and serves as a positioning reference for the workpiece. The clamping plate is slidably fitted in the groove and is positioned opposite to the reference plate. The rotating rod is rotatably mounted in the groove along its extension direction. The thread of the rotating rod passes through the clamping plate. By rotating the rotating rod along its own axis, the clamping plate can be driven to translate along the groove towards or away from the reference plate, thereby clamping or releasing the workpiece.

[0014] As a preferred embodiment of a rotatable fixture, the top edge of the mounting plate, the corresponding position of the fixing plate, and the top edge of the chassis are all provided with coaxial connecting holes, which penetrate the corresponding components in a vertical direction; the mounting plate, fixing plate, and chassis are detachably fixedly connected by fasteners passing through the connecting holes.

[0015] As a preferred embodiment of a rotatable fixture, one end of the rotating rod extending out of the groove is designated as a first grip, and the ends of the connecting rods extending out of the groove are designated as second grips. The first and second grips are respectively used by the operator to hold and apply rotational force, thereby driving the rotating rod to move the clamping plate and driving the connecting rod to rotate the fixed plate.

[0016] As a preferred embodiment of a rotatable fixture, the bottom of the fixed plate is provided with a key extending in a vertical direction, and the toothed body is provided with a keyway adapted to the key. The toothed body is fixed to the bottom of the fixed plate through the cooperation of the key and the keyway.

[0017] As a preferred embodiment of a rotatable fixture, the top of the clamping plate is provided with an extension that extends out of the slide groove, the extension being used to increase the contact area between the clamping plate and the workpiece.

[0018] As a preferred embodiment of a rotatable fixture, the bottom of the fixed plate is provided with a shaft extending downward in a vertical direction, the axis of the shaft coinciding with the rotation axis of the fixed plate; the corresponding position of the chassis is provided with a shaft groove adapted to the shaft, the shaft is rotatably inserted into the shaft groove, and the toothed body is sleeved on the outer periphery of the shaft and fixedly connected to the shaft.

[0019] As a preferred embodiment of a rotatable fixture, a support block is provided inside the groove, and the top surface of the support block is provided with a circular surface for engaging with the connecting rod, the connecting rod being assisted by the circular surface to rotate around its axis.

[0020] The beneficial effects of this invention are as follows: A continuous transmission structure is formed through the meshing of the toothed body and the mating toothed body in the rotating assembly, along with the rotation of the connecting rod. When the operator rotates the connecting rod, the connecting rod rotates around its own axis, driving the mating toothed body to move synchronously, which in turn drives the meshing toothed body and the fixed plate to rotate stably. Ultimately, the workpiece on the fixture rotates synchronously with the fixed plate around the chassis axis. This structure allows the workpiece to complete continuous rotation at multiple angles while clamped, eliminating the need for repeated disassembly and reassembly. This reduces clamping errors and improves the efficiency and accuracy of processing or inspection, making it particularly suitable for multi-faceted operation scenarios. Furthermore, the fixed plate can accommodate different types of fixtures, improving the versatility of the jig. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0039] In one embodiment of this utility model, such as Figure 1-5 As shown, a rotatable fixture is provided, including: a chassis 1, a fixed plate 2, and a rotating assembly 3. The fixed plate 2 is disposed above the chassis 1, and the upper end of the fixed plate 2 is used to mount a clamping body 11. The clamping body 11 is used to clamp the workpiece, and the fixed plate 2 is rotatably mounted on the chassis 1 about an axis perpendicular to the upper surface of the chassis 1 via the rotating assembly 3. The rotating assembly 3 includes a toothed body 301, a mating toothed body 302, and a connecting rod 303. The toothed body 301 is fixed to the lower end face of the fixed plate 2. The mating toothed body 302 is fixed to one end of the connecting rod 303. One end of the connecting rod 303 is rotatably inserted through the chassis 1 and extends into the chassis 1. The mating toothed body 302 extends into the chassis 1 along with the connecting rod 303 and meshes with the toothed body 301. The other end of the connecting rod 303 is located outside the chassis 1 to provide rotational driving force. By driving the connecting rod 303 to rotate, the mating toothed body 302 can be driven to rotate, thereby driving the toothed body 301 and the fixed plate 2 connected to it to rotate around the chassis 1.

[0040] The rotatable fixture provided by this utility model forms a continuous transmission structure through the meshing of the toothed body 301 and the mating toothed body 302 in the rotating component 3 and the rotation of the connecting rod 303. When the operator rotates the connecting rod 303, the connecting rod 303 rotates around its own axis, driving the mating toothed body 302 to move synchronously, thereby driving the meshing toothed body 301 and the fixed plate 2 to rotate stably, ultimately realizing that the workpiece on the fixture body 11 rotates synchronously with the fixed plate 2 around the axis of the chassis 1. This structure allows the workpiece to complete multi-angle continuous rotation in the clamping state without repeated disassembly and reassembly, which reduces clamping errors and improves the efficiency and accuracy of processing or inspection, and is especially suitable for multi-faceted operation scenarios. At the same time, the fixed plate 2 can install different models of fixture bodies 11, improving the versatility of the fixture.

[0041] Preferred, such as Figure 3 As shown, both the toothed body 301 and the mating toothed body 302 are bevel gears, and their axes intersect perpendicularly. The mating toothed body 302 meshes with the beveled toothed body 301 through its beveled tooth surface to achieve the reversal transmission of the rotational motion of the connecting rod 303 to the rotational motion of the fixed plate 2. Through the vertical axis layout and tooth surface meshing structure of the bevel gears, the horizontal rotational motion of the connecting rod 303 can be efficiently converted into the vertical axial rotation of the fixed plate 2, achieving precise reversal of the transmission direction. Due to the large contact area and stable meshing of the beveled tooth surface, the transmission of the rotational driving force is guaranteed to be slip-free, improving transmission efficiency and stability. This solves the problems of limited transmission direction and large space occupation of parallel gears, making the fixture structure more compact.

[0042] In this embodiment, the toothed body 301 and the mating toothed body 302 use two bevel gears, which not only has high rotational efficiency but also allows the use of standard parts, saving manufacturing costs. The toothed body 301 can mate with the fixed plate 2, and the addition of the rotating component 3 and the chassis 1 does not cause the clamping body 11 to lose its function of clamping the workpiece.

[0043] Preferred, such as Figure 5 As shown, the top surface of the chassis 1 is provided with a groove 5, the opening of which faces the fixed plate 2. The internal space of the groove 5 provides clearance for the rotation of the toothed body 301, the meshing motion of the toothed body 302 and the toothed body 301, and the end movement of the connecting rod 303. This avoids interference between the moving parts and the chassis 1. Since the movement trajectory of each part is unobstructed, the rotation assembly 3 is able to transmit smoothly without jamming, thus improving the stability of the fixture operation.

[0044] Preferred, such as Figure 1 As shown, the clamping body 11 includes a mounting plate 111, a rotating rod 112, a reference plate 113, and a clamping plate 114. The mounting plate 111 is fixed to the fixing plate 2. A groove 14 is formed on the top surface of the mounting plate 111 in the horizontal direction. The reference plate 113 is vertically fixed to one side of the top surface of the mounting plate 111 and is used as a positioning reference for the workpiece. The clamping plate 114 is slidably fitted in the groove 14 and is arranged opposite to the reference plate 113. The rotating rod 112 is rotatably mounted in the groove 14 along the extension direction of the groove 14. The thread of the rotating rod 112 passes through the clamping plate 114. By rotating the rotating rod 112 along its own axis, the clamping plate 114 can be driven to translate along the groove 14 towards or away from the reference plate 113, so as to clamp or release the workpiece.

[0045] When the rotating rod 112 rotates along its own axis, the threaded drive clamping plate 114 moves precisely along the slide groove 14, and can move towards or away from the reference plate 113. Since the reference plate 113 provides a clear positioning reference and the slide groove 14 restricts the offset of the clamping plate 114, the workpiece is accurately positioned and stably clamped, avoiding the workpiece from loosening or shifting during operation.

[0046] Specifically, such as Figure 1-5 As shown, the top edge of the mounting plate 111, the corresponding position of the fixing plate 2, and the top edge of the chassis 1 are all provided with coaxial connecting holes 15, which penetrate the corresponding components in the vertical direction; the mounting plate 111, the fixing plate 2, and the chassis 1 are detachably fixedly connected by fasteners that pass through the connecting holes 15.

[0047] The three components can be precisely aligned and fixed, and can be disassembled and separated at any time. Since the connecting hole 15 is coaxial, it ensures assembly accuracy. The detachable design makes it easy to maintain or replace the components individually, thereby improving the overall assembly stability of the fixture and the convenience of later maintenance.

[0048] Furthermore, such as Figure 1-4 As shown, one end of the rotating rod 112 extending out of the slide groove 14 is designated as the first grip part 12, and the end of the connecting rod 303 extending out of the groove 5 is designated as the second grip part 4. The first grip part 12 and the second grip part 4 are respectively used for the operator to hold and apply rotational force, thereby driving the rotating rod 112 to move the clamping plate 114 and driving the connecting rod 303 to rotate the fixed plate 2.

[0049] The operator can hold the grip steadily and apply rotational force precisely to drive the clamping plate 114 to move and the fixed plate 2 to rotate. Because the gripping point is clear and the force is concentrated, slippage or uneven force during operation is avoided, improving the convenience and accuracy of clamping and rotation operations.

[0050] Preferred, such as Figure 4 As shown, the bottom of the fixing plate 2 is provided with a key portion 10 extending in a vertical direction, and the toothed body 301 is provided with a keyway that matches the key portion 10. The toothed body 301 is fixed to the bottom of the fixing plate 2 through the cooperation of the key portion 10 and the keyway.

[0051] The key 10 and the keyway fit together to form a rigid connection, which can transmit torque synchronously without relative sliding. Because the key connection is precisely positioned, it can ensure the coaxiality of the toothed body 301 and the fixed plate 2, thereby ensuring the stability and accuracy of the rotational transmission and avoiding transmission lag or offset caused by loose connection.

[0052] Specifically, such as Figure 1 As shown, the top of the clamping plate 114 is provided with an extension 13, which extends out of the slide groove 14. The extension 13 is used to increase the contact area between the clamping plate 114 and the workpiece.

[0053] When clamped, the pressure can be evenly distributed on the surface of the workpiece, avoiding localized deformation due to pressure, while increasing friction to prevent the workpiece from loosening, thereby ensuring the positional stability and integrity of the workpiece during processing or inspection.

[0054] Preferred, such as Figure 4 As shown, the bottom of the fixing plate 2 is provided with a shaft portion 8 extending downward in the vertical direction, and the axis of the shaft portion 8 is the rotation axis of the fixing plate 2; the corresponding position of the chassis 1 is provided with a shaft groove 9 that is adapted to the shaft portion 8, the shaft portion 8 can be rotatably inserted into the shaft groove 9, and the toothed body 301 is sleeved on the outer periphery of the shaft portion 8 and fixedly connected to the shaft portion 8.

[0055] The shaft 8 can be stably inserted into the shaft groove 9 and the rotation center can be accurately positioned. The toothed body 301 can also remain coaxial when fitted onto the shaft 8. Since the rotation center is fixed and the support is stable, it ensures that the fixed plate 2 rotates without deviation and the teeth mesh accurately, thereby improving the smoothness of transmission and rotation accuracy.

[0056] Specifically, such as Figure 5As shown, a support block 6 is provided inside the groove 5. The top surface of the support block 6 is provided with a circular surface 7 for cooperating with the rotating rod 112. The rotating rod 112 is assisted by the circular surface 7 to rotate around the axis.

[0057] The structure of the internal support block 6 of the groove 5 and the circular surface 7 of the top surface adapted to the rotating rod 112 allows the rotating rod 112 to obtain stable radial support by relying on the circular surface 7 when rotating, thus limiting the offset and sway of the rod.

[0058] In this utility model, the workpiece clamping process is as follows: the workpiece to be processed or inspected is placed on the mounting plate 111 of the clamping body 11, so that one side of the workpiece is in contact with the reference plate 113 to complete precise positioning; then the operator holds the first grip part 12 of the rotating rod 112 and rotates the rotating rod 112 clockwise. When the rotating rod 112 rotates along its own axis, its threaded structure drives the clamping plate 114 to move smoothly along the slide groove 14 of the mounting plate 111 towards the reference plate 113 until the extension part 13 at the top of the clamping plate 114 is in close contact with the other side of the workpiece. The clamping force of the clamping plate 114 and the reference plate 113 is used to stably fix the workpiece and prevent the workpiece from shifting in subsequent operations.

[0059] In this utility model, the rotation process of the fixed plate 2 is as follows: When it is necessary to adjust the angle of the workpiece for operation on different surfaces, the operator holds the second hand grip 4 of the connecting rod 303 and rotates the connecting rod 303; the connecting rod 303 rotates around its own axis and drives the mating tooth 302 at the end to rotate synchronously. The mating tooth 302 meshes with the toothed body 301 fixed to the bottom of the fixed plate 2 through the conical tooth surface, converting the horizontal rotation of the connecting rod 303 into the vertical axial rotation of the toothed body 301; at this time, the fixed plate 2 rotates synchronously and stably with the toothed body 301 around the bottom shaft 8 (the shaft 8 is rotated and positioned in the shaft groove 9 of the chassis 1), thereby driving the upper clamping body 11 and the clamped workpiece to rotate together until the workpiece is adjusted to the required angle, and the angle adjustment of the fixed plate 2 (and the workpiece) is completed by stopping the rotation of the connecting rod 303.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
