Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically the design of an adjustable positioning fixture. Background Technology

[0002] In the field of machining, precise positioning and effective clamping of workpieces are crucial for ensuring machining quality and production efficiency. Traditional machining fixtures are mostly specialized fixtures, designed and manufactured specifically for the shape, size, and machining requirements of a particular workpiece. While specialized fixtures can achieve high production efficiency and machining accuracy when producing a single type of product in large batches, they have limitations in the current multi-variety, small-batch production model. Whenever a new workpiece needs to be machined, companies have to redesign, manufacture, and debug new fixtures. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable positioning fixture that can meet the positioning requirements of different workpieces, has good clamping stability, and can improve production efficiency.

[0004] An adjustable positioning fixture includes a base and an adjustment mechanism, a perforated plate, an adjustable positioning component, and an adjustable clamping mechanism mounted on the base. The perforated plate is mounted on the adjustment mechanism, the adjustable positioning component is movably mounted on the perforated plate, and the adjustable clamping component is disposed adjacent to the perforated plate. The perforated plate has a plurality of mounting holes arranged in an array. The adjustable positioning component includes a positioning rod and a plurality of positioning clamping blocks, and the positioning rod and positioning clamping blocks can be connected to any mounting hole.

[0005] In the above scheme, the position of the perforated plate on the base can be adjusted by the adjustment mechanism. The workpiece to be processed is positioned and fixed on the perforated plate by the adjustable positioning component. Specifically, the positioning rod is fixed on the perforated plate, and the positioning hole on the workpiece is aligned with the positioning rod so that the workpiece is placed on the perforated plate with the positioning rod as the center. This ensures that the workpiece can be quickly positioned when processing the same workpiece. After adjusting the position of the workpiece, the positioning clamp is abutted against the workpiece and locked to any mounting hole by screws or other fasteners. When processing different workpieces, the positioning rod and the positioning clamp can be adjusted on the perforated plate according to the actual situation of the workpiece. The adjustable clamping mechanism can adjust the height according to the position to be clamped on the workpiece. The adjustable positioning component and the adjustable clamping component work together to stably clamp the workpiece.

[0006] Furthermore, the positioning clamp includes a positioning part and a connecting part, the positioning part being perpendicular to the connecting part, and the connecting part having an elongated oval hole.

[0007] In the above scheme, the vertical design of the positioning part and the connecting part allows the positioning part to fit the workpiece surface at a more ideal angle when the positioning clamp block contacts the workpiece. The elongated hole on the connecting part provides flexible adjustment space for the installation of the positioning clamp block. When the positioning clamp block is connected to the perforated plate with fasteners such as screws, the elongated hole allows the positioning clamp block to be finely adjusted within a certain range. Multiple positioning clamp blocks working together to position and clamp the workpiece can improve the clamping stability.

[0008] Furthermore, the bottom of the perforated plate is connected to several support components, each including a support plate and a support base. The support plate is connected to the perforated plate, and the support base is connected to the support plate. The bottom of the support base is provided with a hemispherical support member.

[0009] In the above scheme, several support components are distributed at the bottom of the perforated plate, which can evenly distribute the weight of the perforated plate and the workpiece placed on it to each support point, ensuring that the perforated plate can maintain stable flatness when bearing workpieces of different weights and sizes, providing a solid foundation for workpiece positioning and processing. The bottom of the support base is equipped with a hemispherical support, which allows the support components to rotate and move flexibly within a certain range. When it is necessary to adjust the position of the perforated plate, the worker can relatively easily operate the adjustment device to adjust the position of the perforated plate.

[0010] Furthermore, the adjustment mechanism includes a first adjustment component, a first guide rail slider assembly, a connecting base plate, a second adjustment component, and a second guide rail slider assembly. The connecting base plate is movably connected to the first adjustment component and several sets of the first guide rail slider assemblies. The second adjustment component and several sets of the second guide rail slider assemblies are mounted on the connecting base plate. The perforated plate is connected to the second adjustment component and several sets of the second guide rail slider assemblies. The direction of the second guide rail slider assembly is perpendicular to that of the first guide rail slider assembly.

[0011] In the above scheme, the first adjustment component can adjust the connecting base plate to move along the straight line of the first guide rail slider assembly, and the second adjustment component can adjust the perforated plate to move along the straight line of the second guide rail slider assembly. The direction of the second guide rail slider assembly is perpendicular to the direction of the first guide rail slider assembly. This two-dimensional independent adjustment capability allows the perforated plate to be precisely adjusted to any desired position in the plane.

[0012] Furthermore, the first adjustment assembly includes two connecting seats, a ball screw, and a screw nut. The connecting seats are mounted on the base, the ball screw is rotatably connected to the two connecting seats, one end of the ball screw connected to the adjustment handle extends out of the perforated plate, the screw nut is movably sleeved on the ball screw, and the connecting base plate is connected to the screw nut.

[0013] In the above scheme, two connecting seats are installed on the base and provide rotational support for the ball screw, so that the ball screw can remain stable during rotation. When using the first adjustment component, rotating the adjustment handle drives the ball screw to rotate, and the screw nut will move linearly along the ball screw. This transmission method can accurately convert rotational motion into linear motion, realizing high-precision adjustment of the position of the connecting base plate.

[0014] Furthermore, the adjustable clamping mechanism includes two sets of lifting adjustment components and clamping components. The clamping components include a pull rod, a connecting rod, and a clamping seat. The two ends of the connecting rod are connected to the two sets of lifting adjustment components. The pull rod and the clamping seat are connected to the connecting rod. The clamping seat is equipped with a plurality of lifting and adjusting clamping parts.

[0015] In the above solution, the lifting adjustment component can adjust the height of the clamping component. The pull rod allows the operator to pull the clamping component up and down when adjusting the height of the clamping component. When the workpiece needs to be clamped and is inserted into the clamping seat, the clamping component is adjusted downward to ensure that each clamping component can fully contact the workpiece surface and form a stable clamping force.

[0016] Furthermore, the clamping component includes a pressure plate, a threaded rod, and an adjusting knob. The adjusting knob is connected to one end of the threaded rod, which passes through the top plate of the clamping seat and is threadedly connected to the clamp. The pressure plate is connected to the other end of the threaded rod, and the pressure plate cooperates with the bottom plate of the clamping seat to clamp the workpiece.

[0017] In the above solution, the operator can easily control the rotation of the threaded rod by simply rotating the adjustment knob, thereby raising and lowering the pressure plate. This manual adjustment method does not require complicated tools or equipment, and the operator can adjust it at any time according to actual needs, quickly responding to changes in the workpiece clamping requirements.

[0018] Furthermore, the lifting adjustment assembly includes a fixed base and a screw. The fixed base is mounted on the base, and the screw is vertically mounted on the fixed base. Two fixing nuts are threaded onto the screw. A connecting block is connected to the end of the connecting rod. The connecting block is sleeved on the screw and located between the two fixing nuts.

[0019] In the above scheme, the fixing seat is installed on the base, providing stable support for the screw and ensuring that the screw remains vertical during use without wobbling or tilting. The connecting block is sleeved on the screw and fixed by two fixing nuts. This structural design allows the connecting block to be firmly fixed at any position on the screw, ensuring that the clamping assembly remains stable after height adjustment and will not shift due to vibration or external forces, thereby ensuring the stability of workpiece clamping and the accuracy of machining.

[0020] This utility model discloses an adjustable positioning fixture that is adaptable to the positioning needs of different workpieces, offers good clamping stability, and improves production efficiency. The position of the perforated plate on the base can be adjusted via an adjustment mechanism. The workpiece to be processed is positioned and fixed on the perforated plate by the adjustable positioning assembly. Specifically, a positioning rod is fixed to the perforated plate, and the positioning holes on the workpiece are aligned with the positioning rod, allowing the workpiece to be adjusted and placed on the perforated plate with the positioning rod as the center. This ensures rapid positioning of the workpiece when processing the same workpiece. After adjusting the workpiece's position, a positioning clamping block is abutted against the workpiece and secured to any mounting hole using screws or other fasteners. When processing different workpieces, the positioning rod and positioning clamping block can be adjusted in position on the perforated plate according to the actual workpiece conditions. The adjustable clamping mechanism can adjust the height according to the required clamping position of the workpiece. The combined action of the adjustable positioning assembly and the adjustable clamping assembly ensures stable clamping of the workpiece. Attached Figure Description

[0028] The adjustable positioning fixture of this utility model will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0029] like Figure 1 and Figure 6 As shown in a preferred embodiment, the adjustable positioning fixture of this utility model includes a base 1 and an adjustment mechanism 2, a perforated plate 4, an adjustable positioning component 3, and an adjustable clamping mechanism 5 mounted on the base 1. The perforated plate 4 is mounted on the adjustment mechanism 2, the adjustable positioning component 3 is movably mounted on the perforated plate 4, and the adjustable clamping component 52 is arranged adjacent to the perforated plate 4. The perforated plate 4 has a plurality of mounting holes 41 arranged in an array. The adjustable positioning component 3 includes a positioning rod 32 and a plurality of positioning clamping blocks 31, which can be connected to any mounting hole 41. The position of the perforated plate 4 on the base 1 can be adjusted by the adjustment mechanism 2. The workpiece to be processed is positioned and fixed on the perforated plate 4 by the adjustable positioning component 3. The adjustable clamping mechanism 5 can adjust the height according to the position required for clamping the workpiece. The adjustable positioning component 3 and the adjustable clamping component 52 work together to stably clamp the workpiece.

[0030] The adjustable positioning component 3 specifically fixes the positioning rod 32 onto the perforated plate 4. Here, the positioning rod 32 is threadedly connected to the mounting hole 41. The positioning hole on the workpiece is aligned with the positioning rod 32, so that the workpiece can be adjusted and placed on the perforated plate 4 with the positioning rod 32 as the center. This ensures that the workpiece can be quickly positioned when processing the same workpiece. After adjusting the position of the workpiece, the positioning clamp 31 is abutted against the workpiece, and the positioning clamp 31 is locked onto any mounting hole 41 by screws or other fasteners. When processing different workpieces, the positioning rod 32 and the positioning clamp 31 can be adjusted to their positions on the perforated plate 4 according to the actual situation of the workpiece.

[0031] like Figure 2 As shown, in some embodiments, the positioning clamp 31 includes a positioning part 311 and a connecting part 312. The positioning part 311 is perpendicular to the connecting part 312, and the connecting part 312 is provided with an elongated oval hole 6. The perpendicular design of the positioning part 311 and the connecting part 312 allows the positioning part 311 to fit against the workpiece surface at a relatively ideal angle when the positioning clamp 31 contacts the workpiece. The elongated oval hole 6 on the connecting part 312 provides flexible adjustment space for the installation of the positioning clamp 31. When the positioning clamp 31 is connected to the perforated plate 4 with fasteners such as screws, the elongated oval hole 6 allows the positioning clamp 31 to be finely adjusted within a certain range. Multiple positioning clamps 31 working together to position and clamp the workpiece can improve the clamping stability.

[0032] like Figure 1 and Figure 3 As shown, in some embodiments, the bottom of the perforated plate 4 is connected to several support components 7. Each support component 7 includes a support plate 71 and a support base 72. The support plate 71 is connected to the perforated plate 4, and the support base 72 is connected to the support plate 71. The bottom of the support base 72 is provided with a hemispherical support member 73. The several support components 7 are distributed at the bottom of the perforated plate 4, which can evenly distribute the weight of the perforated plate 4 and the workpiece placed on it to various support points, ensuring that the perforated plate 4 maintains stable flatness when bearing workpieces of different weights and sizes, providing a solid foundation for workpiece positioning and processing. The hemispherical support member 73 at the bottom of the support base 72 allows the support components 7 to rotate and move flexibly within a certain range. When the position of the perforated plate 4 needs to be adjusted, the worker can relatively easily operate the adjustment device to adjust the position of the perforated plate 4.

[0033] like Figure 4 As shown, in some embodiments, the adjustment mechanism 2 includes a first adjustment component 21, a first guide rail slider assembly 22, a connecting base plate 23, a second adjustment component 24, and a second guide rail slider assembly 25. The connecting base plate 23 is movably connected to the first adjustment component 21 and several sets of first guide rail slider assemblies 22. The second adjustment component 24 and several sets of second guide rail slider assemblies 25 are mounted on the connecting base plate 23. The perforated plate 4 is connected to the second adjustment component 24 and several sets of second guide rail slider assemblies 25. The direction of the second guide rail slider assembly 25 is perpendicular to the direction of the first guide rail slider assembly 22. The first adjustment component 21 can adjust the connecting base plate 23 to move along the linear direction of the first guide rail slider assembly 22. The second adjustment component 24 can adjust the perforated plate 4 to move along the linear direction of the second guide rail slider assembly 25. The direction of the second guide rail slider assembly 25 is perpendicular to the direction of the first guide rail slider assembly 22. This two-dimensional independent adjustment capability allows the perforated plate 4 to be precisely adjusted to any desired position in the plane.

[0034] like Figure 5As shown, in some embodiments, the first adjusting assembly 21 includes two connecting seats 211, a ball screw 212, and a screw nut 213. The connecting seats 211 are mounted on the base 1, and the ball screw 212 is rotatably connected to the two connecting seats 211. One end of the ball screw 212, connected to an adjusting handle 214, extends out of the perforated plate 4. The screw nut 213 is movably sleeved on the ball screw 212, and the connecting base plate 23 is connected to the screw nut 213. The two connecting seats 211 are mounted on the base 1 and provide rotational support for the ball screw 212, ensuring stability during rotation. When using the first adjusting assembly 21, rotating the adjusting handle 214 causes the ball screw 212 to rotate, and the screw nut 213 moves linearly along the ball screw 212. This transmission method can accurately convert rotational motion into linear motion, achieving high-precision adjustment of the position of the connecting base plate 23. The second adjusting assembly 24 has the same structure as the first adjusting assembly 21.

[0035] like Figure 4 and Figure 6 As shown, in some embodiments, the adjustable clamping mechanism 5 includes two sets of lifting adjustment components 51 and clamping components 52. The clamping component 52 includes a pull rod 521, a connecting rod 522, and a clamping seat 523.

Several adjustable clamping elements 524 are installed on the clamping seat 523. The lifting adjustment components 51 can adjust the height of the clamping component 52. The pull rod 521 allows the operator to pull the clamping component 52 up and down when adjusting its height. When the workpiece needs to be clamped and extends into the clamping seat 523, the clamping elements 524 are adjusted downwards to ensure that the clamping elements 524 can fully contact the workpiece surface and form a stable clamping force. Here, the height of the number of clamping elements 524 is adjusted according to the number of clamping elements 524 required for the workpiece.

[0036] like Figure 4 As shown, in some embodiments, the clamping member 524 includes a pressure plate 5241, a threaded rod 5242, and an adjusting knob 5243. The adjusting knob 5243 is connected to one end of the threaded rod 5242, which passes through the top plate of the clamping seat 523 and is threadedly connected to the clamp. The pressure plate 5241 is connected to the other end of the threaded rod 5242, and the pressure plate 5241 cooperates with the bottom plate of the clamping seat 523 to clamp the workpiece. The operator only needs to rotate the adjusting knob 5243 to easily control the rotation of the threaded rod 5242, thereby raising and lowering the pressure plate 5241. This manual adjustment method does not require complicated tools or equipment, and the operator can adjust it at any time according to actual needs, quickly responding to changes in workpiece clamping requirements.

[0037] like Figure 6As shown, in some embodiments, the lifting adjustment assembly 51 includes a fixed base 511 and a screw 512. The fixed base 511 is mounted on the base 1, and the screw 512 is vertically mounted on the fixed base 511. Two fixing nuts 513 are threaded onto the screw 512. A connecting block 525 is connected to the end of the connecting rod 522. The connecting block 525 is sleeved on the screw 512 and located between the two fixing nuts 513. The fixed base 511, mounted on the base 1, provides stable support for the screw 512, ensuring that the screw 512 remains vertical during use and does not wobble or tilt. The connecting block 525 is sleeved on the screw 512 and fixed by the two fixing nuts 513. This structural design allows the connecting block 525 to be firmly fixed at any position on the screw 512, ensuring that the clamping assembly 52 remains stable after height adjustment and will not be displaced due to vibration or external force, thereby ensuring the stability of workpiece clamping and the accuracy of processing.

[0038] The present invention relates to an adjustable positioning fixture. The working principle and process are as follows: when processing or inspecting a workpiece, the position of the workpiece is positioned by the positioning rod 32. Multiple positioning clamping blocks 31 are fixed on the perforated plate 4 according to the structure and position of the workpiece, so that the positioning clamping blocks 31 clamp the workpiece. The front, back, left and right positions of the workpiece are adjusted by adjusting the structure. The position of the clamping component 52 is adjusted according to the required clamping height of the workpiece. Then, the workpiece is clamped by the clamping component 524 in conjunction with the clamping seat 523.
