Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a clamp fixing mechanism. Background Art

[0002] In the process of mechanical manufacturing and processing, the fixture is an important tool for fixing the workpiece, which is of great significance for ensuring processing accuracy and improving production efficiency;

[0003] For example, a Chinese utility model patent with announcement number CN218927549U discloses a flexible clamp, including two clamping plates, a clamping drive mechanism and two flexible clamping members; the clamping drive mechanism is connected to the two clamping plates and is used to drive the two clamping plates to move closer to or away from each other; the two flexible clamping members each include a limit housing, a slider, a tension adjustment member, a plurality of telescopic rods, a plurality of first elastic members and a pressure detection member, a slide groove is provided in the limit housing, and a plurality of guide holes connected to the slide groove are opened on the side wall of the limit housing;

[0004] In this comparative document, the workpiece is placed between two flexible clamping members, and then the two clamping plates are driven to approach each other through a clamping drive mechanism, so that the two flexible clamping members are close to each other and clamp the workpiece. When the telescopic rods on the flexible clamping members contact the surface of the workpiece, they will be retracted into the corresponding guide holes to different degrees according to the shape of the workpiece surface (correspondingly, each first elastic member will shrink to different degrees), so as to achieve multi-point clamping of the workpiece surface. However, after working for a long time, multiple elastic members will lose their elasticity, resulting in poor clamping effect. Replacing the clamping members as a whole wastes resources, and it is difficult for the device to ensure the synchronous movement of the two flexible clamping members, so there is a large room for improvement.

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a clamp fixing mechanism, referring to Figure 1-Figure 4 , including a fixed seat 1, electric cylinders 3 are arranged on both sides of the fixed seat 1, and the two electric cylinders 3 are fixedly connected to the fixed seat 1 through a supporting block 4, and the supporting block 4 supports the electric cylinder 3, and the output ends of the two electric cylinders 3 rotate through the two ends of the fixed seat 1 and are fixedly connected with sliders 5, and the two sides of the fixed seat 1 are fixedly connected with slide rails 2, and the two ends of the slider 5 are respectively slidably connected to the two slide rails 2, and one side of the two sliders 5 is fixedly connected with a clamping assembly through a plurality of bolts 11, and the clamping assembly includes a telescopic part, a shell 8 and a bottom plate 9, and the two electric cylinders 3 are electrically connected to the external controller, and the manual operation external controller can synchronously start the two electric cylinders 3, and the telescopic ends of the two electric cylinders 3 can drive the two sliders 5 to move back and forth stably along the slide rail 2, and then the workpiece is stably fixed by the two clamping assemblies according to the size of the workpiece, and the two clamping assemblies can make corresponding changes at the contact point with the workpiece according to the external shape of the workpiece, so as to stably clamp workpieces of various sizes and shapes.

[0022] Reference Figure 3 and Figure 4A plurality of holes 16 are provided on one side of the shell 8, and the shell 8 is fixedly connected to the bottom plate 9 by four bolts 10. The telescopic member includes a limit block 12, a support rod 13, a spring 14 and a rubber head 15. A slide groove is provided on one side of the limit block 12, one end of the support rod 13 is fixedly connected to the rubber head 15, the other end of the support rod 13 is fixedly connected to the spring 14, the other end of the spring 14 is fixedly connected to one end of the slide groove, the support rod 13 is slidably connected to the slide groove, and the plurality of support rods 13 are respectively adapted to the plurality of holes 16, and the plurality of elastic members are respectively inserted into the plurality of holes 16 through the plurality of support rods 13, and then the bottom plate 9 and the shell 8 are fixed by bolts 10, so as to fix the plurality of telescopic members. When the plurality of support rods 13 clamp the workpiece, the rubber head 15 is connected The workpiece surface can be touched to prevent scratching of the workpiece surface. Multiple support rods 13 move backward with the shape of the workpiece, and the spring 14 on the side of the corresponding support rod 13 is squeezed, so that the clamping surface of the clamping assembly is completely fitted with the surface shape of the workpiece to stably clamp it. The spring 14 will lose its elasticity after working for a long time and needs to be replaced in time. The workpiece can be taken out, and all the springs 14 are restored under the action of the rebound force. A plate is placed vertically on one side of the rubber head 15. People can observe with the naked eye which telescopic parts have rubber heads 15 that are not in contact with the plate, which indicates that the spring 14 has lost part of its elasticity. If it has affected the use, the four bolts 10 can be unscrewed, the bottom plate 9 can be opened, and the corresponding telescopic parts can be replaced, so as to facilitate the maintenance of the clamping assembly at any time and maintain the clamping effect.

[0023] Reference Figure 1 and Figure 2 , racks 6 are fixedly connected to the opposite sides of the two sliders 5, and a gear 7 is rotatably connected to the top of the fixed seat 1. The two racks 6 are respectively meshed with the two sides of the gear 7. As the two sliders 5 move, the two racks 6 move in opposite directions and mesh with the gear 7 to drive the gear 7 to rotate, thereby facilitating the synchronization of the extension and retraction of the two electric cylinders 3 and making the two clamping assemblies move synchronously.

[0024] The implementation principle of a clamp fixing mechanism in an embodiment of the present application is as follows: by setting a clamping assembly, a gear and a rack, the workpiece is placed between the two clamping assemblies, and the manually operated external controller can synchronously start the two electric cylinders 3. The telescopic ends of the two electric cylinders 3 can drive the two slide blocks 5 to move relative to each other along the slide rails 2. As the two slide blocks 5 move, the two racks 6 move in the opposite direction and mesh with the gear 7 to drive the gear 7 to rotate, thereby facilitating the synchronization of the telescopic movement of the two electric cylinders 3, so that the two clamping assemblies move synchronously. When the multiple support rods 13 clamp the workpiece, the rubber head 15 contacts the surface of the workpiece to prevent the surface of the workpiece from being scratched. The multiple support rods 13 move backward along the shape of the workpiece, and the corresponding support rods 1 3, the spring 14 on one side is squeezed, so that the clamping surface of the clamping assembly completely fits the surface shape of the workpiece and stably clamps it. The spring 14 will lose its elasticity after working for a long time and needs to be replaced in time. The workpiece can be taken out, and all the springs 14 are restored under the action of the rebound force. A plate is placed vertically on one side of the rubber head 15. People can observe with the naked eye which rubber heads 15 of the telescopic parts are not in contact with the plate, which shows that the spring 14 has lost some of its elasticity. If it has affected the use, the four bolts 10 can be unscrewed, the bottom plate 9 can be opened, and the corresponding telescopic parts can be replaced, so as to facilitate the maintenance of the clamping assembly at any time and maintain the clamping effect. It has the effect of stably clamping special-shaped workpieces of various sizes and facilitating the timely maintenance of the clamping assembly.
