Description

Technical Field

[0001] This application relates to the field of fixing fixture technology, and more particularly to an adjustable fixing device. Background Technology

[0002] Fixtures are devices used in metal processing to position and clamp workpieces. They ensure the workpiece is stable during processing and prevent vibration or displacement from affecting accuracy. They typically consist of positioning elements, clamping mechanisms, and bases. Clamping force is applied mechanically or hydraulically. They are suitable for metal workpieces of different shapes and sizes. If the workpiece is not fixed during metal processing, it is easy for it to shift due to the force of the tool, resulting in dimensional deviations, excessive surface roughness, or even safety accidents. Therefore, fixtures are needed to clamp and fix it.

[0003] Chinese Patent No. CN214444115U discloses a metal processing fixing device, including a base. A hydraulic cylinder is fixedly connected to the right side of the upper surface of the base. The output end of the hydraulic cylinder is fixedly connected to the right side of a first clamping block. A first support plate is fixedly connected to the middle left side of the first clamping block. This metal processing fixing device, through the hydraulic cylinder, enables the first clamping block to move left and right. The cooperation of the first and second support plates provides support for the metal plate. The cooperation of the first clamping blocks fixes the metal plate. The combination of a drive motor, a driving wheel, a driven wheel, and bolts allows the pressure plate to limit the upper and lower positions of the metal plate.

[0004] However, in the aforementioned patent, when clamping and fixing metal parts, it is necessary to use a hydraulic cylinder to drive the movement of the first clamping block on one side in order to clamp and fix the metal parts. The distance between the first clamping block and the second clamping block is small, so it is difficult to adjust the distance between the two clamping blocks. This has limitations when clamping and fixing metal parts with larger dimensions, reducing the flexibility when fixing metal parts. Therefore, in order to solve the above problems, we provide an adjustable fixing device. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable fixing device to solve the problem mentioned in the background art that when clamping and fixing metal parts, it is necessary to use a hydraulic cylinder to drive the movement of the first clamping block on one side in order to clamp and fix the metal parts. However, the distance between the first clamping block and the second clamping block is small, so it is difficult to adjust the distance between the two clamping blocks. This has limitations when clamping and fixing larger metal parts and reduces the flexibility when fixing metal parts.

[0006] The embodiments of this application adopt the following technical solutions: An adjustable fixing device includes a carrier plate, a fixing pressure member fixedly mounted on the upper surface of the carrier plate, a movable pressure member disposed above the carrier plate, an adjusting plate disposed on one side of the carrier plate, a fixing cover fixedly embedded on one side of the adjusting plate, an electro-hydraulic actuator fixedly mounted on the inner wall of the fixing cover, the telescopic end of the electro-hydraulic actuator fixedly mounted to one side of the movable pressure member, an adjusting transmission member disposed below the carrier plate, the adjusting transmission member including a drive motor fixedly mounted on the bottom surface of the carrier plate, a drive shaft fixedly mounted on the output end of the drive motor, a drive gear fixedly connected to the outer surface of the drive shaft, a transmission plate fixedly connected to one side of the adjusting plate, a toothed plate fixedly connected to the bottom surface of the transmission plate, and the top end of the drive gear meshing with the bottom surface of the toothed plate.

[0007] Preferably, the fixed pressing component includes a support stand, one side of which has a transmission cavity. A first bearing is fixedly embedded in the inner wall of the transmission cavity. A transmission screw is fixedly connected to the inner ring of the first bearing. A threaded lifting plate is threadedly connected to the outer surface of the transmission screw. A fixed pressure plate is fixedly connected to one side of the threaded lifting plate. The threaded lifting plate is located above the carrier plate. A rotating handwheel is fixedly installed at the top of the transmission screw.

[0008] Preferably, a groove is provided on one side of the carrier plate, and a slide plate is slidably connected to the inner wall of the groove. One side of the slide plate is fixedly connected to one side of the adjustment plate.

[0009] Preferably, a sliding hole is provided on one side of the adjusting plate, and a sliding rod is slidably connected to the inner wall of the sliding hole. One end of the sliding rod is fixedly connected to one side of the moving pressing member. An adjusting hole is provided on the bottom surface of the carrier plate, and the transmission plate is located inside the adjusting hole.

[0010] Preferably, a support side plate is fixedly installed on the bottom surface of the carrier plate, a second bearing is fixedly embedded on one side of the support side plate, the inner ring of the second bearing is fixedly connected to the outer surface of the drive shaft, a stable support is fixedly connected to the bottom surface of the carrier plate, and a shock-absorbing pad is fixedly connected to the bottom surface of the stable support.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. This adjustable fixing device allows for flexible adjustment of the distance between the moving and fixed pressing parts by adjusting the transmission components. The drive motor rotates the drive shaft and drive gears, enabling meshing transmission between the gears and the toothed plate. This allows the adjusting plate to move the moving pressing part stably. Combined with the guide plate within the slide groove, the distance adjustment range is widened, accommodating metal parts of different specifications. This improves the versatility and flexibility of the fixing operation, solving the problem of traditional methods that rely on hydraulic cylinders to move the clamping blocks, resulting in small initial clamping distances and narrow adjustment ranges, making it difficult to adapt to large-sized metal parts and limiting the fixing operation.

[0012] 2. This adjustable fixing device, by driving the transmission screw in the fixed pressing component, allows the threaded lifting plate to drive the fixed pressure plate to apply vertical pressure from the top. The moving pressing component can be horizontally clamped from the side under the action of the electro-hydraulic push rod, and can be repeatedly pressed down from the top to fix it, forming a three-dimensional fixing structure with top and side cooperation. At the same time, the sliding of the slide rod in the sliding hole ensures stable side clamping and avoids displacement of metal parts during processing. This not only ensures processing accuracy but also reduces safety hazards caused by workpiece loosening, improving the efficiency and reliability of metal processing. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Example 1 As attached Figure 1 , Figure 2 and Figure 3 An adjustable fixing device is shown, including a carrier plate 1. A fixing pressure member 2 is fixedly installed on the upper surface of the carrier plate 1. A movable pressure member 3 is provided above the carrier plate 1. An adjusting plate 4 is provided on one side of the carrier plate 1. A fixing cover 5 is fixedly embedded on one side of the adjusting plate 4. An electro-hydraulic actuator 7 is fixedly installed on the inner wall of the fixing cover 5. The telescopic end of the electro-hydraulic actuator 7 is fixedly installed with one side of the movable pressure member 3. An adjusting transmission member 6 is provided below the carrier plate 1. The adjusting transmission member 6 includes a drive motor 61 fixedly installed on the bottom surface of the carrier plate 1. A drive shaft 62 is fixedly installed on the output end of the drive motor 61. A drive gear 63 is fixedly connected to the outer surface of the drive shaft 62. A transmission plate 67 is fixedly connected to one side of the adjusting plate 4. A toothed plate 66 is fixedly connected to the bottom surface of the transmission plate 67. The top end of the drive gear 63 meshes with the bottom surface of the toothed plate 66.

[0017] As can be seen from the above description, this utility model has the following beneficial effects: by adjusting the setting of the transmission component 6, the distance between the movable pressing component 3 and the fixed pressing component 2 can be flexibly adjusted. The drive motor 61 drives the drive shaft 62 and the drive gear 63 to rotate, which enables the gear and the toothed plate 66 to mesh and transmit power. This allows the adjusting plate 4 to drive the movable pressing component 3 to move stably. With the guide of the slide plate 8 in the slide groove 12, the distance adjustment range can be widened, adapting to metal parts of different specifications and improving the versatility and flexibility of the fixed operation.

[0018] Example 2 Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: like Figure 1 and Figure 2 As shown, in a preferred embodiment, the fixed pressing member 2 includes a support base 21. A transmission cavity 22 is provided on one side of the support base 21. Two first bearings 23 are fixedly embedded in the inner wall of the transmission cavity 22. The inner rings of the two first bearings 23 are fixedly connected to a transmission screw 24. A threaded lifting plate 25 is threadedly connected to the outer surface of the transmission screw 24. A fixed pressure plate 26 is fixedly connected to one side of the threaded lifting plate 25. The threaded lifting plate 25 is located above the carrier plate 1. A rotating handwheel 27 is fixedly installed at the top of the transmission screw 24. Furthermore, the support base 21 provides stable support, and the transmission cavity 22 provides space for the threaded lifting plate 25 to move. When the rotating handwheel 27 is rotated, the transmission screw 24 rotates smoothly within the two first bearings 23. Through threaded engagement, the threaded lifting plate 25 moves up and down along the cavity, enabling the fixed pressure plate 26 to press or release the top of the metal part, achieving reliable vertical fixation, adapting to the clamping requirements of workpieces of different thicknesses, and improving the controllability of the fixing operation.

[0019] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in a preferred embodiment, two grooves 12 are provided on one side of the carrier plate 1. Slide plates 8 are slidably connected to the inner walls of both grooves 12. The sides of the two slide plates 8 that are close to each other are fixedly connected to the two sides of the adjusting plate 4. Two sliding holes 10 are provided on one side of the adjusting plate 4. Two sliding rods 9 are slidably connected to the inner walls of both sliding holes 10. One end of each sliding rod 9 is fixedly connected to one side of the moving pressing member 3. An adjusting hole 68 is provided on the bottom surface of the carrier plate 1. A transmission plate 67 is located inside the adjusting hole 68. Two supporting side plates 64 are fixedly installed on the bottom surface of the carrier plate 1. Second bearings 65 are fixedly embedded on the sides of the two supporting side plates 64 that are close to each other. The inner rings of the two second bearings 65 are fixedly connected to the outer surfaces of both ends of the drive shaft 62. Two sets of stable supports 11 are fixedly connected to the bottom surface of plate 1. Both stable supports 11 are fixedly connected to the bottom surface of shock-absorbing pads. Furthermore, when the slide plate 8 slides along the slide groove 12, it can provide guidance and constraint for the adjusting plate 4 to prevent it from deviating during movement. The combination of the slide hole 10 and the slide rod 9 ensures that the moving pressing part 3 moves horizontally accurately. When the electro-hydraulic push rod 7 extends and retracts, the slide rod 9 slides along the slide hole 10 to limit the movement trajectory of the moving pressing part 3, ensuring that the side clamping force is evenly applied to the workpiece and enhancing the fixing stability. The drive shaft 62 rotates stably in the support side plate 64 through two second bearings 65, reducing the vibration when the drive gear 63 meshes with the toothed plate 66. The two sets of stable supports 11 and the bottom shock-absorbing pads reduce the overall vibration of the device and prevent the device from shaking during processing.

[0020] The working process of this utility model is as follows: When using this adjustable fixing device, first activate the adjusting transmission component 6. The drive motor 61 outputs power to drive the drive shaft 62 to rotate, which causes the drive gear 63 on the surface of the drive shaft 62 to rotate accordingly. By using the drive gear 63 to mesh with the toothed plate 66 on the bottom surface of the transmission plate 67, the transmission plate 67 can be moved within the adjusting hole 68, thereby causing the adjusting plate 4 connected to the transmission plate 67 to move. By sliding the adjusting plate 4, the distance between the moving lower pressure component 3 and the fixed lower pressure component 2 can be adjusted to adapt to the size of the metal part to be fixed.

[0021] After the spacing is adjusted, place the metal part and rotate the rotating handwheel 27 at the top of the transmission screw 24 in the fixed pressing part 2. The transmission screw 24 rotates in the two first bearings 23, driving the threaded lifting plate 25 with the threaded connection on the outer surface to move down along the transmission cavity 22, so that the fixed pressure plate 26 on one side of the threaded lifting plate 25 presses the metal part from above. Then, the electro-hydraulic push rod 7 in the fixed cover 5 extends and pushes the moving pressing part 3 to move. The moving pressing part 3 drives the slide rod 9 to slide in the slide hole 10, clamping the other side of the metal part from the side. Then, according to the fixing method of the fixed pressing part 2, the metal part is pressed down and fixed from the top again, thus completing the fixing process of the metal part, which is convenient for subsequent processing. This is the working process and working principle of the device.
