Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a rapid positioning device for circular parts. Background Technology

[0002] In the field of machining, round parts are widely used due to their structural characteristics, and their rapid and accurate positioning is a key link to ensure production efficiency and product quality.

[0003] However, although existing devices can achieve basic positioning functions, in practical applications, when dealing with circular parts of different diameters or when it is necessary to quickly adjust the fixture between different workstations, existing devices often lack effective adaptive adjustment mechanisms.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a rapid positioning device for circular parts is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a rapid positioning device for circular parts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quick positioning device for circular parts, comprising: a connecting seat, a support frame disposed on the upper surface of the connecting seat, a mounting block disposed on one side of the support frame, and a U-shaped frame disposed on one side of the mounting block;

[0007] A V-shaped groove is provided on one side of the mounting block, and two adjustment grooves are provided on both sides of the mounting block;

[0008] Adjustment blocks are fixedly connected to the inner walls of opposite sides of the U-shaped frame, and the adjustment blocks are engaged with the adjustment slots.

[0009] A clamping screw is provided on one side of the U-shaped frame.

[0010] In a preferred embodiment of the present invention, the bottom of the support frame is fixedly connected to the upper surface of the connecting seat, and one side of the mounting block is fixedly connected to one side of the support frame.

[0011] In a preferred embodiment of this invention, the V-groove is vertically arranged.

[0012] In a preferred embodiment of the present invention, the adjusting block and the adjusting groove are in clearance fit, so that the adjusting block can slide along the adjusting groove without obstruction, and the radial wobble between the adjusting block and the adjusting groove is less than 0.5 mm.

[0013] In a preferred embodiment of this utility model, the U-shaped frame is provided with a threaded hole that engages with the clamping screw, and the clamping screw can move along the axis of the threaded hole by rotation.

[0014] In a preferred embodiment of this utility model, the screw hole is located at the center of the U-shaped frame.

[0015] In a preferred embodiment of this utility model, a rubber pad is adhered to one end of the clamping screw.

[0016] In a preferred embodiment of this invention, the central axis of the clamping screw intersects perpendicularly with the center line of the V-groove.

[0017] In a preferred embodiment of this utility model, a weight-adding seat is threadedly connected to the bottom of the connecting seat.

[0018] In a preferred embodiment of this utility model, an anti-slip pad is adhered to the bottom of the weight-adding seat.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides a quick positioning device for circular parts. By using the self-centering property of the V-shaped surface through the vertically set V-shaped groove, when the circular part is placed in the groove, it can automatically align with the center of the circle and achieve rapid radial positioning. After the inclined surface of the V-shaped groove contacts the outer circle of the part, it naturally constrains the degree of freedom of the part in the horizontal plane. No complicated adjustment is required, which can reduce the time of manual intervention and improve the operation efficiency. Compared with the existing technology, which requires manual calibration and positioning, it can avoid positioning deviation caused by human error.

[0021] (2) This utility model provides a quick positioning device for circular parts. The U-shaped frame is fixedly connected to the inner side of the adjustment block and the adjustment grooves on both sides of the mounting block. The adjustment block and the adjustment groove are in clearance fit. The radial wobble is strictly controlled within 0.5mm. This allows the device body to allow the U-shaped frame to slide along the groove to adapt to parts of different sizes, while minimizing the cumulative error caused by wobble. This ensures high positioning repeatability and consistency in multiple uses. Compared with the common loose fit in the prior art, which causes unstable positioning, this device overcomes the drift problem that is easy to occur in traditional devices by optimizing the clearance design.

[0022] (3) This utility model provides a quick positioning device for circular parts. The central axis of the clamping screw intersects perpendicularly with the center line of the V-groove, and a rubber pad is attached to the end of the screw. The perpendicular intersecting layout allows the clamping force to pass through the center of the part, avoiding deflection or lifting during clamping, while the rubber pad provides flexible buffering. The direct effect is to achieve reliable clamping without damaging the surface of the part, thus enhancing operational safety. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] like Figure 1 As shown, a quick positioning device for circular parts includes: a connecting seat 1, a support frame 3 disposed on the upper surface of the connecting seat 1, a mounting block 4 disposed on one side of the support frame 3, and a U-shaped frame 7 disposed on one side of the mounting block 4.

[0031] like Figure 1-2 As shown, the bottom of the support frame 3 is fixedly connected to the upper surface of the connecting seat 1, one side of the mounting block 4 is fixedly connected to one side of the support frame 3, and the bottom of the connecting seat 1 is threadedly connected to the weight-adding seat 2, and the bottom of the weight-adding seat 2 is glued with an anti-slip pad.

[0032] A V-groove 6 is provided on one side of the mounting block 4. The V-groove 6 is set vertically. Two adjustment grooves 5 are provided on both sides of the mounting block 4.

[0033] In this embodiment, the support frame 3 is fixedly connected to the upper surface of the connecting seat 1 to form the main support structure of the device, ensuring overall rigidity. The mounting block 4 is set on one side of the support frame 3, and the V-groove 6 on one side of the mounting block 4 is vertically set, which can effectively accommodate round parts and utilize the self-centering characteristics of the V-shaped surface to achieve rapid preliminary positioning of the parts, which can reduce manual adjustment time and improve operating efficiency, and is particularly suitable for batch operation scenarios.

[0034] The adjustment slots 5 on both sides of the mounting block 4 are symmetrically distributed, providing an installation interface for the U-shaped frame 7 and allowing a certain amount of adjustment space. The adjustment slots 5 are machined with high precision to ensure the stability of the fit with the adjustment block 10 and avoid positioning errors caused by excessive gaps.

[0035] The weight-adding seat 2 at the bottom of the connecting seat 1 is connected by a thread, which is convenient for disassembly and replacement. The weight of the device can be adjusted according to actual needs, enhancing the vibration resistance. The anti-slip pad is attached to the bottom of the weight-adding seat 2 to increase the friction with the workbench surface and prevent the device from sliding during operation.

[0036] like Figure 3-4 As shown, adjusting blocks 10 are fixedly connected to the inner walls of opposite sides of the U-shaped frame 7. The adjusting blocks 10 are engaged with the adjusting grooves 5. The adjusting blocks 10 and the adjusting grooves 5 are in clearance fit, and the radial wobble between the adjusting blocks 10 and the adjusting grooves 5 is less than 0.5 mm.

[0037] In this embodiment, the U-shaped frame 7 is engaged with the adjustment slot 5 on the mounting block 4 via the adjustment block 10, enabling quick assembly and disassembly. The adjustment block 10 and the adjustment slot 5 are in clearance fit, but the radial wobble is strictly controlled within 0.5mm to ensure high-precision positioning and reduce the cumulative error when clamping parts. This ensures that the device maintains consistency during repeated use and is suitable for precision machining scenarios.

[0038] The clearance fit between the adjusting block 10 and the adjusting groove 5 allows for minor thermal expansion or deformation compensation, avoiding jamming problems caused by temperature changes, so that the adjusting block 10 can slide freely without excessive shaking after being inserted into the adjusting groove 5.

[0039] like Figure 1-4 As shown, a clamping screw 8 is provided on one side of the U-shaped frame 7. A screw hole is provided on the U-shaped frame 7 that is threaded to the clamping screw 8. The screw hole is located at the center of the U-shaped frame 7. The clamping screw 8 can be moved along the axis of the screw hole by rotation. A rubber pad 9 is attached to one end of the clamping screw 8. The central axis of the clamping screw 8 intersects perpendicularly with the center line of the V-groove 6.

[0040] In this embodiment, the vertical setting of the V-groove 6 utilizes the weight of the part itself to achieve automatic positioning. The central axis of the clamping screw 8 and the center line of the V-groove 6 are strictly perpendicular to each other, ensuring that the applied clamping force passes through the center of the part. This in principle prevents the part from deflecting or lifting during the clamping process, laying the foundation for achieving high repeatability positioning accuracy. It is particularly suitable for high-frequency and high-precision operation scenarios such as inspection and assembly.

[0041] In actual operation, the V-groove 6 mainly undertakes the radial positioning function. Through its two inclined surfaces contacting the outer circle of the part, it constrains the four degrees of freedom of the part in the horizontal plane. Then, the clamping screw 8 is rotated so that the rubber pad 9 at its end moves axially and contacts the part, completing the axial clamping and fixing, and constraining the remaining degrees of freedom.

[0042] The flexible design of the rubber pad 9 provides cushioning and protection, effectively preventing damage to the surface of the parts and enhancing the reliability of clamping by increasing friction. This "V-groove 6 radial positioning + screw axial clamping" mode allows the device to adapt to parts of different diameters within a certain size range, enabling rapid changeover without replacing parts, and making it highly versatile.

[0043] When using this utility model, the circular part is placed in the V-groove 6 of the mounting block 4. The vertical setting and inclined structure of the V-groove 6 allow the part to fall naturally by its own weight, achieving initial radial positioning. The setting of the V-groove 6 allows the outer circle of the part to contact the two inclined surfaces, automatically centering and reducing the need for manual adjustment.

[0044] Next, according to the size or position requirements of the part, the position of the U-shaped frame 7 relative to the V-groove 6 is finely adjusted by moving the adjusting block 10 on the sliding U-shaped frame 7 within the adjusting groove 5 of the mounting block 4. The clearance between the adjusting block 10 and the adjusting groove 5 ensures smooth sliding, while controlling the radial wobble within 0.5mm to maintain positioning accuracy.

[0045] Finally, the clamping screw 8 on the rotating U-shaped frame 7 is moved along the axis of the screw hole until the rubber pad 9 at the end contacts the surface of the part. By continuously rotating, an appropriate clamping force is applied to complete the axial fixation of the part, ensuring that the central axis of the clamping screw 8 intersects perpendicularly with the center line of the V-groove 6, thus preventing the part from shifting.

[0046] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
