Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically to a quick-change tool structure. Background Technology

[0002] In the field of machining, the efficiency of tool changing directly affects the continuity of the production line and the processing cost. Traditional tool installation methods usually rely on multiple bolt fixings or complex disassembly steps, such as using an Allen wrench to loosen screws one by one, disassembling the spindle connector and tool. Each tool change is time-consuming and seriously restricts production efficiency.

[0003] Although existing technologies have proposed quick-change structures that are achieved through electronic control or other transmission structures, i.e., quick-change operation is achieved by mechanical cams, hydraulic or pneumatic mechanisms, such operation can shorten tool change time, but the structure is complex and the failure rate is high, and the maintenance cost is significantly increased. Utility Model Content

A dovetail block is fixedly connected to the movable plate, and a connecting plate is fixedly connected to the dovetail block. A rectangular bonding plate is fixedly connected to the dovetail bonding plate. Two dovetail bonding plates and two rectangular bonding plates are symmetrically arranged. The two rectangular bonding plates can be respectively bonded to both sides of the connecting plate, and the two dovetail bonding plates can be respectively bonded to both sides of the dovetail block. The connecting plate is provided with a mating groove. The rectangular bonding plate located on the front side of the two rectangular bonding plates is fixedly connected with a fixing groove. A plug-in structure is slidably connected in the fixing groove and can be inserted into the mating groove.

[0006] The plug-in structure includes a T-shaped rod that is slidably connected to a fixed slot, a plug-in connector that is fixedly connected to the T-shaped rod, and a compression spring that is fixedly connected between the plug-in connector and the fixed slot.

[0019] A quick-change tool structure includes a movable plate 101 and a dovetail bonding plate 301. A dovetail block 201 is fixedly connected to the movable plate 101, and a connecting plate 202 is fixedly connected to the dovetail block 201. A rectangular bonding plate 302 is fixedly connected to the dovetail bonding plate 301. Two dovetail bonding plates 301 and two rectangular bonding plates 302 are symmetrically arranged. The two rectangular bonding plates 302 can be respectively bonded to both sides of the connecting plate 202, and the two dovetail bonding plates 301 can be respectively bonded to both sides of the dovetail block 201. The connecting plate 202 is provided with a mating groove 205. The rectangular bonding plate 302 located on the front side of the two rectangular bonding plates 302 is fixedly connected to a fixing groove 304. A plug-in structure is slidably connected in the fixing groove 304, and the plug-in structure can be inserted into the mating groove 205.

[0020] A cutting tool is connected between the two rectangular bonding plates 302. When the cutting tool needs to be connected to the dovetail block 201, the two dovetail bonding plates 301 are continuously moved downwards, causing the two rectangular bonding plates 302 to move downwards, which in turn causes the two rectangular bonding plates 302 to move downwards until the fixed slot 304 and the mating slot 205 coincide. At this time, the insertion structure can quickly enter the mating slot 205, thereby connecting the cutting tool to the connecting plate 202 and completing the quick installation of the cutting tool. When the cutting tool needs to be disassembled and replaced, the insertion structure can be slid in the fixed slot 304, thereby sliding the insertion structure out of the mating slot 205. At this time, the insertion structure will no longer restrict the mating slot 205, and the dovetail bonding plate 301 can be moved upwards to remove the cutting tool, thereby completing the quick replacement of the cutting tool.

[0021] The arrangement of two rectangular bonding plates 302 that can be bonded to both sides of the connecting plate 202 and two dovetail bonding plates 301 that can be bonded to both sides of the dovetail block 201 ensures that the tool will not move horizontally, while the plug-in structure restricts the tool from moving vertically, thereby ensuring the stability of the tool in the subsequent machining process. Under the premise of ensuring the quick-change structure, the subsequent machining can be carried out stably.

[0022] The plug-in structure includes a T-shaped rod 401 that is slidably connected to a fixed slot 304, a plug 402 that is fixedly connected to the T-shaped rod 401, and a compression spring 404 that is fixedly connected between the plug 402 and the fixed slot 304.

[0023] When the dovetail bonding plate 301 is moved downward, the T-shaped rod 401 is pulled first to retract the connector 402 into the fixing slot 304, thereby ensuring that the connector 402 is misaligned with the connecting plate 202, thus ensuring that the dovetail bonding plate 301 can move downward smoothly. When the dovetail bonding plate 301 moves to the installation position, since the fixing slot 304 and the mating slot 205 overlap, the connector 402 will be quickly inserted into the mating slot 205 by the elastic force of the compression spring 404, thereby completing the restriction between the tool and the connecting plate 202, and thus completing the installation effect of the tool.

[0024] When it is necessary to disassemble the tool, first pull the T-shaped rod 401 and then insert the connector 402 back into the fixing slot 304. Then slide the dovetail bonding plate 301 up to complete the tool disassembly, thereby realizing the quick tool change operation.

[0025] It also includes an inclined plate 206 fixed to the connecting plate 202, and the plug 402 is provided with an arc-shaped chamfer 403.

[0026] When applying a pulling force to the T-shaped rod 401 and continuously lowering the dovetail bonding plate 301, once the curved chamfer 403 contacts the inclined plate 206, the operator can remove the force pulling the T-shaped rod 401 and only need to focus on applying a downward pushing force to the dovetail bonding plate 301. During this process, the curved chamfer 403 will gradually be pushed by the inclined plate 206, which will gradually cause the T-shaped rod 401 to overcome the elastic force of the compression spring 404 and slide, which will facilitate subsequent installation operations. This will make it easier for the operator to install without continuously applying a pulling force to the T-shaped rod 401.

[0027] The maximum position that the inclined plate 206 can reach in the horizontal direction is the position that coincides with the rear side of the connecting plate 202, so as to ensure that when the dovetail bonding plate 301 slides down, the rectangular bonding plate 302 will not interfere with the inclined plate 206.

[0028] It also includes an assembly slot 306 formed on the rear rectangular bonding plate 302.

[0029] The assembly groove 306 is designed to ensure that the rear assembly groove 306 will not interfere with the mating groove 205 when the dovetail bonding plate 301 slides down, so that the rear assembly groove 306 can move down smoothly, which brings convenience to the tool installation process.

[0030] The two rectangular bonding plates 302 are fixed together by a transverse plate 303.

[0031] By connecting the cutting tools to the transverse plate 303 in an integral molding or welding manner, multiple cutting tools of different shapes can be connected to multiple different transverse plates 303, which brings convenience to subsequent processing operations.

[0032] It also includes a base plate 204 fixed to the underside of the dovetail block 201.

[0033] The base plate 204 is designed so that when the dovetail bonding plate 301 is lowered, once the dovetail bonding plate 301 abuts against the base plate 204, it indicates that the tool has reached the current installation position, and the plug-in structure can be inserted into the mating slot 205 for display. At the same time, the base plate 204 can support the dovetail bonding plate 301 in the vertical direction, further ensuring the stability of the tool.

[0034] It also includes a fixed plate 501, and a rectangular rod 102 is fixedly connected to the movable plate 101. The rectangular rod 102 is slidably connected to the fixed plate 501.

[0035] During processing, multiple rectangular rods 102 are operated to slide on the fixed plate 501, thereby adjusting the position of the tool and causing the tool to move forward or backward during processing, thus completing the subsequent processing task.

[0036] Multiple rectangular rods 102 are provided, and all of the multiple rectangular rods 102 are slidably connected to the fixed plate 501.

[0037] The arrangement of multiple rectangular rods 102 can further ensure the stability of the moving plate 101 during the movement process, and provide a more stable guarantee for subsequent processing.

[0038] A connecting piece A502 is fixedly connected to the fixed plate 501, an electric push rod 503 is fixedly connected to the connecting piece A502, a connecting piece B504 is fixedly connected to the telescopic rod of the electric push rod 503, and the telescopic rod of the connecting piece B504 is fixedly connected to the moving plate 101.

[0039] The fixed plate 501 is fixed by screwing multiple bolts into it. When the moving plate 101 needs to be moved, the telescopic rod of the electric push rod 503 extends and pushes the moving plate 101 to slide through the connecting piece B504, thus achieving the effect of driving the tool to move.

[0040] The connection piece A502 and the connection piece B504 facilitate the connection between the connection piece A502 and the fixed plate 501 and the movable plate 101.

[0041] Each of the rectangular bonding plates 302 has multiple threaded holes B305, and the connecting plate 202 has multiple threaded holes A203.

[0042] When a certain type of tool needs to be used for a long time without replacement, bolts can be screwed into the multiple one-to-one connecting threaded holes B305 and A203 to more firmly fix the two rectangular bonding plates 302 for a long time, providing convenience for long-term use.
