Description

Technical Field

[0001] This utility model relates to the field of gantry planer technology, and in particular to a bidirectional tool post for a gantry planer. Background Technology

[0002] A gantry planer is a large planing machine tool mainly used for machining large workpieces or medium-sized workpieces in mass production. Its structural feature is a rectangular bed with a column on each side, resembling a "gantry," hence the name gantry planer. The main motion of the gantry planer is the reciprocating linear motion of the worktable, while the feed motion is the transverse or vertical movement of the planer head along the crossbeam guide rail. It can machine complex shapes such as planes, inclined planes, and curved surfaces, and features high machining accuracy and high production efficiency. It is widely used in heavy machinery, shipbuilding, metallurgy, mining, and other industries. Gantry planers can be divided into two main categories according to their structure and working performance: single-column and double-column. Double-column gantry planers offer better rigidity and stability and are suitable for machining large workpieces.

[0003] In the current field of machining, the clamping and fixing of planing tools in the traditional gantry planer bidirectional tool post mainly relies on manual operation. This process not only consumes a lot of manpower and time, but is also inefficient in the installation and removal of tools. In addition, due to the instability of manual operation, this clamping and fixing method is difficult to guarantee the accuracy of tool installation, which may affect the dimensional accuracy and surface quality of the machined parts. Utility Model Content

[0004] One objective of this invention is to provide a bidirectional tool holder for a gantry planer. This invention addresses the problem mentioned in the background that the clamping and fixing of planing tools in traditional bidirectional tool holders for gantry planers mainly relies on manual operation. This process not only consumes a lot of manpower and time, but is also inefficient in the installation and removal of tools. Furthermore, due to the instability of manual operation, this clamping and fixing method cannot guarantee the accuracy of tool installation, which may affect the dimensional accuracy and surface quality of the machined parts.

[0005] A bidirectional tool post for a gantry planer according to an embodiment of the present invention includes a planer structure. The planer structure includes a worktable, and side sliding structures are slidably connected to both sides of the worktable. Each side sliding structure includes a side sliding table and a side sliding block. The side sliding table is slidably connected to both sides of the worktable, and a side sliding block is slidably connected to the side surface of the side sliding table. A lifting structure is installed on the side surface of the side sliding block, and the lifting structure includes a top sliding block. A tool disassembly and assembly structure is installed on the lower surface of the top sliding block. The tool disassembly and assembly structure includes a clamping block and a clamping block. The lower surface of the top sliding block... The surface has a cutting groove, and a first switch is installed at the top of the cutting groove. One end of the lower surface of the top sliding block has a sliding groove, and a drive motor is installed at one end of the sliding groove. The output end of the drive motor is connected to a bidirectional threaded rod. Both ends of the surface of the bidirectional threaded rod are threaded with clamping blocks. Both ends of the inner surface of the clamping block are installed with telescopic rods. The output end of the telescopic rod is installed with a clamping block. A spring structure is installed between the clamping block and the clamping block. A second switch is installed on the outer surface of the clamping block through a fixing block. A connecting block is fixedly connected to the outer surface of the clamping block.

[0006] Preferably, the clamping block is made of hard rubber, and the inner surface of the clamping block has a groove.

[0007] Preferably, a bottom drive motor is mounted on the side surface of the worktable, and the output end of the bottom drive motor is connected to a bottom threaded screw, with the side sliding table threadedly connected to the surface of the bottom threaded screw.

[0008] Preferably, both ends of the lower surface of the worktable are fixedly connected to bottom limit rods, and the side sliding table is slidably connected to the surface of the bottom limit rods.

[0009] Preferably, a side drive motor is fixedly connected to the outer surface of the side sliding table, and a side threaded screw is driven to the output end of the side drive motor. The side sliding block is threadedly connected to the surface of the side threaded screw.

[0010] Preferably, the inner surface of the side sliding platform is fixedly connected to both the upper and lower ends of the side limiting rods, and the side sliding block is slidably connected to the surface of the side limiting rods.

[0011] Preferably, a top drive motor is fixedly connected to the upper surface of the side sliding block, and a top threaded screw is driven to the output end of the top drive motor. The top sliding block is threadedly connected to the surface of the top threaded screw.

[0012] Preferably, a top limiting rod is fixedly connected to both ends of the side surface of the side sliding block, and the top sliding block is slidably connected to the surface of the top limiting rod.

[0013] The beneficial effects of this utility model are:

[0014] This utility model, through its specially designed tool assembly and disassembly structure, allows for the installation of tools on a gantry planer. The tool is inserted into the tool slot, and its tip touches a first switch. This switch activates the drive motor, causing the bidirectional threaded rod to rotate. This causes two clamping blocks, threaded at both ends of the bidirectional threaded rod, to slide towards the center. This, in turn, moves a clamping block mounted on the inner surface of the clamping blocks towards the center. The four clamping blocks clamp and fix the tool at four different positions on its side surface, ensuring stability during planing. As the drive motor continues to run, the clamping blocks gradually compress the spring structure outwards. When the spring structure is compressed to its limit, the connecting block touches the second switch, which controls the drive motor to stop running, thus enabling the tool installation process. When removing the tool, the drive motor is controlled to run in reverse through the control terminal, causing the bidirectional threaded rod to rotate in the opposite direction, which causes the clamping block to slide towards both ends, thereby releasing the middle tool. This significantly improves the efficiency and accuracy of tool installation on the gantry planer, while reducing the intensity of manual operation and potential safety risks. In addition, this structure simplifies the tool loading and unloading process, making tool replacement faster, thereby improving the overall processing efficiency and production automation level.

[0015] This invention, through the configuration of a bottom drive motor, a side drive motor, and a top drive motor, allows for machining of different positions on the workpiece along the Y-axis. The bottom drive motor rotates the threaded screw at the lower center of the worktable, causing the side sliding block at the upper end of the worktable to slide back and forth. The side drive motor rotates the side threaded screw, causing the side sliding block to slide left and right, thus machining different positions on the X-axis. The top drive motor rotates the top threaded screw, causing the top sliding block to slide up and down, adjusting the tool height and enabling machining of different positions on the Z-axis.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-5A gantry planer bidirectional tool holder includes a planer structure 1. The planer structure 1 includes a worktable 101. Side sliding structures 2 are slidably connected to both sides of the worktable 101. Each side sliding structure 2 includes a side sliding table 201 and a side sliding block 205. The side sliding table 201 is slidably connected to both sides of the worktable 101. The side sliding block 205 is slidably connected to the side surface of the side sliding table 201. A lifting structure 3 is installed on the side surface of the side sliding block 205. The lifting structure 3 includes a top sliding block 304. A tool disassembly and assembly structure 4 is installed on the lower surface of the top sliding block 304. The tool disassembly and assembly structure 4 includes a clamping block 406 and a clamping block 409. A tool groove 40 is formed on the lower surface of the top sliding block 304. 1. A first switch 402 is installed at the top of the inner cavity of the blade groove 401. A sliding groove 403 is formed at one end of the lower surface of the top sliding block 304. A drive motor 404 is installed at one end of the sliding groove 403. A bidirectional threaded rod 405 is connected to the output end of the drive motor 404. Clamping blocks 406 are threaded to both ends of the surface of the bidirectional threaded rod 405. Telescopic rods 407 are installed at both ends of the inner surface of the clamping block 406. A clamping block 409 is installed at the output end of the telescopic rod 407. A spring structure 408 is installed between the clamping block 409 and the clamping block 406. A second switch 410 is installed on the outer surface of the clamping block 406 through a fixing block. A clamping block 409 is fixedly connected to the outer surface of the clamping block 409. When installing a cutting tool on a gantry planer, the connecting block 411 inserts the tool into the tool slot 401, and the tip of the tool touches the first switch 402. The first switch 402 controls the drive motor 404 to start, driving the bidirectional threaded rod 405 to rotate. This causes the two clamping blocks 406, which are threaded to both ends of the surface of the bidirectional threaded rod 405, to slide towards the center. This causes the clamping blocks 409, which are installed on the inner surface of the clamping blocks 406, to move towards the center. The four clamping blocks 409 clamp and fix the tool at four different positions on the side surface, ensuring the stability of the tool during planing. As the drive motor 404 continues to run, the clamping blocks 409 gradually press the spring structure 408 outward. When the spring structure 408 is compressed to its limit, the connecting block 411 touches the second switch 410, which controls the drive motor 404 to stop running, thus enabling the tool installation process. When removing the tool, the drive motor 404 is controlled to run in reverse through the control terminal, which drives the bidirectional threaded rod 405 to rotate in reverse, causing the clamping block 406 to drive the clamping block 409 to slide towards both ends, thereby releasing the intermediate tool. This significantly improves the efficiency and accuracy of tool installation on the gantry planer, while reducing the intensity of manual operation and potential safety risks. In addition, this structure simplifies the tool loading and unloading process, making tool replacement faster, thereby improving the overall processing efficiency and production automation level.

[0025] Example 1: The clamping block 409 is made of hard rubber. The hard rubber material of the clamping block 409 increases the friction between the clamping block 409 and the cutting tool, further preventing the stability of the cutting tool structure during planing. The inner surface of the clamping block 409 has a groove, which makes the clamping block 409 fit the side surface of the planing tool more closely.

[0026] Example 2: A bottom drive motor 102 is mounted on the side surface of the worktable 101. The output end of the bottom drive motor 102 is connected to a bottom threaded screw. The side sliding table 201 is threadedly connected to the surface of the bottom threaded screw. Bottom limit rods 103 are fixedly connected to both ends of the lower surface of the worktable 101. The side sliding table 201 is slidably connected to the surface of the bottom limit rods 103. During planing, the bottom drive motor 102 can drive the threaded screw in the middle part of the lower end of the worktable 101 to rotate, thereby driving the side sliding table 201 at the upper end of the worktable 101 to slide back and forth, so as to achieve the purpose of processing different positions of the workpiece along the Y-axis. A side drive motor 202 is fixedly connected to the outer surface of the side sliding table 201. The output end of the side drive motor 202 is connected to a side threaded screw 204. A side sliding block 205 is threadedly connected to the surface of the side threaded screw 204. The upper and lower ends of the inner surface of the side sliding table 201 are connected to the bottom limit rod 103. Each component is fixedly connected to a side limiting rod 203. A side sliding block 205 is slidably connected to the surface of the side limiting rod 203. The side drive motor 202 drives the side threaded screw 204 to rotate, thereby causing the side sliding block 205 to slide left and right, achieving the purpose of machining different positions of the workpiece along the X-axis. A top drive motor 301 is fixedly connected to the upper surface of the side sliding block 205. The output end of the top drive motor 301 is driven by the top threaded screw 303. The top sliding block 304 is threadedly connected to the surface of the top threaded screw 303. Both ends of the side surface of the side sliding block 205 are fixedly connected to the top limiting rod 302. The top sliding block 304 is slidably connected to the surface of the top limiting rod 302. The top drive motor 301 drives the top threaded screw 303 to rotate, causing the top sliding block 304 to slide up and down, achieving the purpose of adjusting the height of the tool and machining different positions of the workpiece along the Z-axis.

[0027] When using this gantry planer's bidirectional tool post for machining, firstly, insert the tool to be machined into the tool slot 401 until the tip of the tool touches the first switch 402. The first switch 402 controls the start of the drive motor 404. The drive motor 404 drives the bidirectional threaded rod 405 to rotate, causing the clamping block 406 to slide towards the center. The clamping block 409 then moves towards the center, clamping and fixing the tool at four different positions on its side surface through the four clamping blocks 409, ensuring tool stability. When the spring structure 408 is compressed to its limit, the connecting block 411 touches the second switch 410, and the drive motor 404 stops running, completing the tool installation. Next, the bottom drive motor 102 controls the back-and-forth sliding of the worktable 101 to achieve machining at different positions on the Y-axis of the workpiece; the side drive motor 202 controls the left-and-right sliding of the side sliding block 205 to achieve machining at different positions on the X-axis of the workpiece; finally, the top drive motor 301 adjusts the up-and-down sliding of the top sliding block 304 to achieve adjustment of the tool height and machining at different positions on the Z-axis of the workpiece. After machining is completed, the drive motor 404 is reversed, causing the clamping block 406 to slide the clamping block 409 to both ends, releasing the tool and facilitating disassembly. The entire process achieves efficient and precise tool installation and workpiece machining.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
