Description

Technical Field

[0001] This utility model belongs to the field of tool transfer technology, specifically a clamping and transfer fixture suitable for tools with complex shapes. Background Technology

[0002] During the transfer process, the cutting tool needs to be clamped and fixed to prevent damage to the transfer tool. According to the patent document with authorization announcement number "CN205614355U" and invention title "Cutting Tool Holding Device," the description states that when in use, the drive body drives the drive shaft to retract away from the mounting base, causing the two clamping parts to rotate synchronously around their respective pivot points to move closer together. At this time, the clamping part clamps the fixing sleeve, thereby clamping and fixing the cutting tool for processing. When processing is completed or when a tool change is needed, the drive shaft, driven by the drive body, extends towards the mounting base, causing the two clamping parts to rotate synchronously around their respective pivot points to move away from each other. At this time, the clamping part releases the fixing sleeve, thereby releasing the cutting tool for removal. However, the following drawbacks still exist:

[0003] When the tool to be transferred is of a complex shape, clamping the tool with the clamping part may result in a small clamping area between the clamping part and the tool, leading to poor clamping stability. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a clamping and transfer fixture suitable for complex-shaped tools, which effectively solves the problem of poor clamping stability when clamping complex-shaped tools.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Depend on Figure 1-6 The present invention relates to a clamping and transfer fixture suitable for complex-shaped cutting tools, comprising two clamping plates 1, surface clamping components 2 uniformly installed on one side of the two clamping plates 1 that are close to each other, and a connecting snap-fit ​​component 3 installed on the clamping plate 1, the connecting snap-fit ​​component 3 being used to install another clamping plate 1 on the side of the clamping plate 1.

[0026] The surface clamping assembly 2 includes a fixed cylinder 201 uniformly installed on the clamping plate 1. A limiting block 202 is movably installed inside the fixed cylinder 201. A clamping rod 203 is installed on the side of the limiting block 202 away from the clamping plate 1. A compression spring 204 is installed on the side of the limiting block 202 away from the clamping rod 203. The two clamping plates 1 are close to each other, so that the end of the clamping rod 203 contacts the surface of the complex-shaped tool. The limiting block 202 at one end of the clamping rod 203 is movably installed in the fixed cylinder 201, so that each clamping rod 203 can move and the end of each clamping rod 203 can contact the surface of the complex-shaped tool, thereby increasing the clamping area and improving the clamping stability.

[0027] The connecting snap-fit ​​assembly 3 includes a connecting groove 301 formed on one side of the clamping plate 1, and a connecting strip 302 installed on the other side of the clamping plate 1. The connecting strip 302 on one side of the clamping plate 1 can be installed into the connecting groove 301 on the other clamping plate 1. A slot 303 is formed on the side of the connecting strip 302 away from the clamping plate 1. A movable groove 304 is formed inside the clamping plate 1. A rod groove 305 is formed on the side of the movable groove 304 near the connecting groove 301. The rod groove 305 extends into the interior of the connecting groove 301. The rod groove 305 and the slot 303 are coaxially arranged. A snap rod 306 is movably installed inside the rod groove 305. One end of the snap rod 306 is located inside the movable groove 304. A movable block 307 is longitudinally slidably installed inside the movable groove 304. The movable block 307 is located above the snap rod 306. The bottom end of the movable block 307 is hinged. There is a connecting rod 308, the bottom end of which is hinged to one end of the clamping rod 306. A return spring 309 is fixedly installed at the bottom end of the movable block 307, and the bottom end of the return spring 309 is fixedly connected to the inner bottom wall of the movable groove 304. A screw cylinder 310 is installed at the top of the clamping plate 1, and a pressing screw 311 is installed on the internal thread of the screw cylinder 310. The bottom end of the pressing screw 311 contacts the top wall of the movable block 307. A connecting groove 301 is opened on one side of the clamping plate 1, and a connecting strip 302 is installed on the other side of the clamping plate 1. Multiple clamping plates 1 can be connected and installed through the connecting groove 301 and the connecting strip 302, which is convenient for clamping large and complex shaped tools. At the same time, by turning the pressing screw 311, the clamping rod 306 is pushed outward and inserted into the clamping groove 303, which can clamp and fix multiple clamping plates 1 for easy clamping.

[0028] A base 4 is provided below the clamping plate 1. A sliding groove 5 is provided on the base 4. Sliding blocks 6 are fixedly installed at the bottom ends of the two clamping plates 1. The sliding blocks 6 are slidably installed inside the sliding groove 5. A double-ended screw 7 is rotatably installed inside the sliding groove 5. The two sliding blocks 6 are respectively threaded to two threaded grooves with opposite directions on the double-ended screw 7. One end of the double-ended screw 7 is fixedly connected to the output shaft of the drive motor 8. The drive motor 8 is fixedly installed on the base 4.

[0029] Working principle: During operation, the complex-shaped tool to be transferred is first placed between two clamping plates 1. Then, the drive motor 8 is turned on, causing the double-ended screw 7 to rotate. Since the sliding blocks 6 at the bottom of the two clamping plates 1 are threadedly connected to the threaded grooves with opposite directions on the double-ended screw 7, the two clamping plates 1 are driven to move closer to each other. Fixed cylinders 201 are evenly installed on the side where the two clamping plates 1 are close to each other. The limiting block 202 at one end of the clamping rod 203 is movably installed inside the fixed cylinder 201. After the end of the clamping rod 203 contacts the tool, the clamping plate 1 continues to move, causing the compression spring 204 to be compressed. Each clamping rod 203 contacts the surface of the complex-shaped tool, increasing the clamping area of ​​the complex-shaped tool and thus improving the clamping stability. During clamping, the elastic force of each compression spring 204 generates a clamping force on the complex-shaped tool, completing the clamping.

[0030] When the complex-shaped tool is large, the connecting strip 302 of the other clamping plate 1 is inserted into the connecting groove 301 on one side of the clamping plate 1, thereby increasing the clamping area and making it easier to clamp the large-sized complex-shaped tool. During installation, the extrusion screw 311 is turned so that the extrusion screw 311 pushes the movable block 307 downward, and then pushes the locking rod 306 outward through the connecting rod 308 to lock into the locking groove 303 on the connecting strip 302 on one side of the other clamping plate 1, thereby locking and fixing the two clamping plates 1.
