[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1 to 5 The present invention provides a technical solution: a clamping device for wear-resistant parts, including a support platform 1, a plurality of support legs 11 provided on the bottom edge of the support platform 1, the support legs 11 being fastened to the machine tool by bolts, and the support platform 1 being used to place the workpiece to be processed;

[0025] like Figure 1 As shown, two strip seats 3 are slidably provided at the top central axis of the support platform 1. When a part is placed on the support platform 1, the two strip seats 3 can be used to position both ends of the part. Figure 1 As shown, at least one dovetail groove 2 is provided at the top center axis position of the support platform 1. Figure 1 The structure has two dovetail grooves 2, with strip-shaped seats 3 positioned above and at both ends of the dovetail grooves 2. Each strip-shaped seat 3 has a dovetail block 5 at its bottom that matches the dovetail groove 2. The dovetail block 5 is movably positioned within the dovetail groove 2, allowing the strip-shaped seat 3 to slide along the dovetail groove 2. Figure 1 As shown, a stop 4 is provided on the side of the two strip seats 3 that are close to each other. The stop 4 is a columnar structure, and each dovetail block 5 is provided with a bolt that can be adjusted to a preset position. When the dovetail block 5 is adjusted to the preset position, it can be positioned by the bolt.

[0026] The specific operation process is as follows, such as Figure 4 and Figure 5 As shown, when the part is placed on the support platform 1, the strip seat 3 can be adjusted to move towards the part so that the abutment 4 abuts against the side of the part. In this way, the two abutments 4 can position the two ends of the part. For different sizes of parts, the position of the abutment 4 can be adjusted to clamp them again.

[0027] The above process clamps both ends of the part, but the sides of the part also need to be fixed, such as...Figure 1 As shown, support plates 9 are provided on both sides of the support platform 1, with both the upper and lower ends of the support plates 9 extending outside the support platform 1. Multiple abutment rods 6 are movably installed inside the top of each support plate 9, allowing each abutment rod 6 to extend and retract freely within the support plate 9. All abutment rods 6 are located above the support platform 1. To improve the support of the abutment rods 6, a support sleeve 8 is movably fitted onto each abutment rod 6. The support sleeve 8 is installed on the support plate 9. The support sleeve 8 increases the contact area between the abutment rod 6 and the support plate 9, giving the abutment rod 6 higher support strength and stability.

[0028] Each support rod 6 is equipped with a positioning mechanism that can be adjusted to a preset position. The positioning device is a locking bolt 7 set on the top of the support plate 9 and positioned corresponding to each support rod 6. Tightening the locking bolt 7 abuts against the support rod 6. Designing the positioning mechanism as only the locking bolt 7 is not only simple and practical, but also allows the locking bolt 7 to stably abut the support rod 6, giving the support rod 6 sufficient stability.

[0029] The two support plates 9 are respectively connected to the drive mechanism located below the support platform 1, such as... Figure 2 and Figure 3 As shown, the drive mechanism includes a mounting shaft 16 installed in the middle of the bottom surface of the support platform 1. A transmission gear 17 is rotatably mounted on the mounting shaft 16. A rack 15 meshes with each side of the transmission gear 17, and the rack 15 is mounted on the drive shaft 14. The end of the drive shaft 14 away from the transmission gear 17 is perpendicularly connected to the support plate 9. A first guide seat 12 is movably provided on each drive shaft 14, and the first guide seat 12 is installed below the support platform 1.

[0030] A telescopic mechanism 19 is provided parallel to one of the drive shafts 14. One end of the telescopic mechanism 19 is connected to the drive shaft 14 via a support 20, and the other end is fixed to the bottom surface of the support platform 1 via a bracket 21. The telescopic mechanism 19 is used to drive the drive shaft 14 to extend or retract. This telescopic mechanism 19 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. When the telescopic mechanism 19 extends or retracts, it can cause the drive shaft 14 to lengthen or shorten, thereby causing the drive shaft 14 to move the two support plates 9 closer together or further apart. Figure 4 and Figure 5 As shown, driven by the drive mechanism, the support plate 9 moves closer to or further away from the center of the support platform 1, so that the abutment rod 6 abuts against the two sides of the part.

[0031] To make the support plate 9 more stable, at least one guide shaft 10 is vertically installed on each support plate 9. A second guide seat 13 is movably mounted on the guide shaft 10. The second guide seat 13 is fixed to the bottom surface of the support platform 1. The second guide seat 13 and the first guide seat 12 are both installed at the bottom edge of the support platform 1.

[0032] Furthermore, such asFigure 2 As shown, the end of the drive shaft 14 away from the support plate 9 is movably placed in the limiting seat 18. The limiting seat 18 is used to support the tail of the drive shaft 14 and the rack 15 to prevent them from bending and deforming.

[0033] In summary, such as Figure 4 As shown, the clamping device proposed in this application can fix regular parts (mainly for rectangles and squares). When the part is placed in the middle of the support platform 1, the abutment 6 is moved closer to the sides of the part so that the abutment 6 abuts against the side of the part.

[0034] like Figure 5 As shown, the parts at this time are irregularly shaped parts (including circular, triangular or curved parts). Before clamping, each locking bolt 7 needs to be loosened. Then, control the abutment 6 to slowly move closer to the part. Since the periphery of the part is irregularly shaped, when the abutment 6 contacts the side of the part, the end of the abutment 6 abuts against the side of the part. Multiple abutments 6 can be arranged around the surface of the part. At this time, tighten each locking bolt 7 to fix each abutment 6. After fixing, the abutments 6 can be used to clamp the processed irregularly shaped parts in batches.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
