Description

Technical Field

[0001] This utility model relates to the field of adjusting shaft processing technology, specifically to a fixing device for adjusting shaft processing. Background Technology

[0002] An adjustment shaft is a mechanical component used to adjust and control the functions of equipment. It typically consists of a mounting section, an adjustment section, and an operating section. The design and function of each part vary depending on the specific application. It is widely used in many fields, such as CNC lathes, automobile engines, optical instruments, and semiconductor manufacturing.

[0003] Currently, when machining the adjusting shaft, it is often necessary to fix it. However, the existing fixing devices mostly rely on turning the handle to drive the screw and move the clamping plate to clamp the shaft on both sides. This is not only inconvenient and difficult to quickly and effectively fix the shaft, but also has poor stability and is prone to lateral or longitudinal movement, which greatly affects the effectiveness of the device. Utility Model Content

[0004] The purpose of this invention is to provide a fixing device for adjusting shaft processing. By symmetrically arranging two sets of fixing plates, a first support arm, a lower support seat, a cylinder, and a slide, the two fixing plates can be controlled to move the lower support seat closer or further away via the first support arm. This allows the distance between the two sets of lower support seats to be adjusted according to the length of the adjusting shaft, so that both ends of the adjusting shaft can be placed on the two lower support seats respectively. Furthermore, by arranging a second support arm, an upper support seat, and a drive mechanism, the second support arm can be controlled to lower the upper support seat and press it against the adjusting shaft, thus pressing the end of the adjusting shaft between the lower and upper support seats. With the cooperation of the two sets of symmetrical structures, the adjusting shaft can be effectively clamped and fixed, thereby solving the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for adjusting shaft machining, comprising:

[0006] A fixed platform, wherein movable fixed plates are symmetrically arranged at both ends of the top side of the fixed platform, and a first support arm is fixed to the bottom inner side of each of the two fixed plates, and a lower support base is connected to the top of the first support arm.

[0007] A second support arm is provided on the inner top of the two fixed plates near the top of the first support arm. The bottom end of the second support arm is fixed with an upper support seat facing the lower support seat, and a positioning mechanism is provided on the top side of the second support arm. A sliding groove is provided on the inner side of the fixed plate, and a connecting block is slidably connected inside the sliding groove. One end of the connecting block is fixedly connected to the second support arm, and the other end of the connecting block extends into the fixed plate and is provided with a driving mechanism.

[0008] Preferably, cylinders are fixedly connected to both ends of the top of the fixed platform via brackets, the output ends of the two cylinders are fixedly connected to the two fixed plates respectively, and sliders are fixed to the bottom ends of the two fixed plates. A slide rail matching the slider is opened on the top side of the fixed platform.

[0009] Preferably, the driving mechanism includes a first motor fixedly connected to the back of the fixed plate, the output end of the first motor extending into the fixed plate and connected to a gear, a toothed column that meshes with the gear being slidably connected to one side of the fixed plate, and one end of the connecting block extending into the fixed plate being fixedly connected to the toothed column.

[0010] Preferably, a limiting block is provided at one end of the toothed column, and a limiting groove matching the limiting block is provided on the inner side of the fixing plate.

[0011] Preferably, the positioning mechanism includes a fixed frame fixed at one end of the top side of the second support arm near the upper support seat. A movable plate is provided on the inner side of the fixed frame. Both ends of the movable plate extend outside the fixed frame and are fixed with blocks. Two positioning arms are symmetrically connected to the bottom two sides of the fixed frame through a pivot. Both ends of the two positioning arms are symmetrically connected to the upper blocks through a pivot with connecting rods. Rubber pads are provided on the inner side of the positioning arms.

[0012] Preferably, a threaded rod is rotatably connected inside the fixed frame via a bearing, and a second motor is fixed to the top of the fixed frame, with the output end of the second motor connected to the threaded rod.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By symmetrically arranging two sets of fixed plates, a first support arm, a lower support seat, a cylinder, and a slide, the two fixed plates can be controlled to move the lower support seat closer or further away via the first support arm. This allows the distance between the two sets of lower support seats to be adjusted according to the length of the adjusting shaft, so that both ends of the adjusting shaft can be placed on the two lower support seats respectively. Furthermore, by arranging a second support arm, an upper support seat, and a drive mechanism, the second support arm can be controlled to move the upper support seat down and press it against the adjusting shaft. This ensures that the end of the adjusting shaft is pressed between the lower and upper support seats. With the cooperation of the two sets of symmetrical structures, the adjusting shaft can be effectively clamped and fixed.

[0015] By setting up a positioning mechanism, when the upper support seat descends and presses against the adjusting shaft, the two sets of symmetrical positioning arms at both ends of the upper support seat can rotate inward synchronously, so that the two symmetrical positioning arms drive the rubber pads to close inward and press against both sides of the adjusting shaft, thereby further positioning and reinforcing the adjusting shaft, greatly improving the stability of the adjusting shaft when it is fixed.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-5 The adjusting shaft machining fixing device shown includes:

[0026] A fixed platform 1 is provided with movable fixed plates 4 symmetrically arranged at both ends of the top side of the fixed platform 1. A first support arm 6 is fixed to the bottom inner side of each of the two fixed plates 4. A lower support seat 7 is connected to the top of the first support arm 6.

[0027] Cylinders 2 are fixedly connected to both ends of the top of the fixed platform 1 via brackets. The output ends of the two cylinders 2 are fixedly connected to the two fixed plates 4 respectively. Slider 5 is fixed to the bottom of the two fixed plates 4. A slide rail 3 matching the slider 5 is opened on the top side of the fixed platform 1.

[0028] By activating cylinder 2, cylinder 2 can push and pull fixed platform 1 to move. Fixed platform 1 can drive slider 5 to slide along slide rail 3. Then fixed platform 1 can drive lower support seat 7 to move through first support arm 6, thereby controlling the two lower support seats 7 to move closer or further apart, so as to adjust the distance between the two sets of lower support seats 7 according to the length of the adjusting shaft, so that the two ends of the adjusting shaft can be placed on the two lower support seats 7 respectively.

[0029] A second support arm 8 is provided on the inner top of the two fixed plates 4 near the top of the first support arm 6. The bottom end of the second support arm 8 is fixed with an upper support seat 9 facing the lower support seat 7. A positioning mechanism is provided on the top side of the second support arm 8. A sliding groove 16 is provided on the inner side of the fixed plate 4. A connecting block 15 is slidably connected inside the sliding groove 16. One end of the connecting block 15 is fixedly connected to the second support arm 8, and the other end of the connecting block 15 extends into the fixed plate 4 and is provided with a driving mechanism.

[0030] The drive mechanism includes a first motor 10 fixedly connected to the back of the fixed plate 4. The output end of the first motor 10 extends into the fixed plate 4 and is connected to a gear 11. A toothed column 12 that meshes with the gear 11 is slidably connected to one side of the interior of the fixed plate 4. One end of the connecting block 15 extending into the interior of the fixed plate 4 is fixedly connected to the toothed column 12.

[0031] A limiting block 13 is provided at one end of the toothed column 12, and a limiting groove 14 matching the limiting block 13 is provided on the inner side of the fixing plate 4. Based on this, by setting the limiting block 13 and the limiting groove 14, the toothed column 12 can drive the limiting block 13 to slide in the limiting groove 14, thereby further supporting and limiting the toothed column 12, greatly ensuring the stability of the toothed column 12 when it moves.

[0032] After placing both ends of the adjusting shaft on the two lower support seats 7 respectively, the first motor 10 is started, which drives the gear 11 to rotate. The gear 11 then drives the gear column 12 to mesh, causing the gear column 12 to drive the connecting block 15 to slide along the slide groove 16. Then, the connecting block 15 can drive the upper support seat 9 to descend through the second support arm 8, so that the upper support seat 9 can be pressed against the adjusting shaft, and the end of the adjusting shaft is pressed between the lower support seat 7 and the upper support seat 9. With the cooperation of the two sets of lower support seats 7 and upper support seats 9, the adjusting shaft can be effectively clamped and fixed.

[0033] The positioning mechanism includes a fixed frame 17 fixed at one end of the top side of the second support arm 8 near the upper support seat 9. A movable movable plate 18 is provided on the inner side of the fixed frame 17. Both ends of the movable plate 18 extend outside the fixed frame 17 and are fixed with blocks 19. Two positioning arms 20 are symmetrically connected to the bottom two sides of the fixed frame 17 through a pivot. Both ends of the two positioning arms 20 are symmetrically connected to the upper block 19 through a pivot with connecting rods 21. A rubber pad 24 is provided on the inner side of the positioning arm 20.

[0034] The fixed frame 17 is rotatably connected to a threaded rod 22 via a bearing, and a second motor 23 is fixed to the top of the fixed frame 17. The output end of the second motor 23 is connected to the threaded rod 22.

[0035] After the upper support seat 9 descends and presses against the adjusting shaft, the second motor 23 is started, which drives the threaded rod 22 to rotate. Then, the threaded rod 22 drives the movable plate 18 to slide within the fixed frame 17, causing the movable plate 18 to move the stops 19 at both ends. Afterward, the stops 19 can drive the two symmetrical positioning arms 20 to rotate synchronously through the connecting rod 21, so that the two symmetrical positioning arms 20 drive the rubber pads 24 to close inward and press against both sides of the adjusting shaft, thereby further positioning and reinforcing the adjusting shaft, greatly improving the stability of the adjusting shaft when it is fixed.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
