Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a machine tool convenient for stable feeding. Background Technique

[0002] A numerically controlled machine tool, also known as a CNC lathe, that is, a computer numerically controlled lathe, is currently the numerically controlled machine tool with the largest usage and the widest coverage in China. However, when the existing numerically controlled machine tools are in use, manual feeding is generally adopted, and the efficiency is not high.

[0003] For example, a feeding structure for a numerically controlled machine tool with automatic positioning disclosed in the publication number CN220825708U. This device uses a feeding structure for a numerically controlled machine tool with automatic positioning, eliminating the need for manual feeding, improving work efficiency, and automatically positioning the raw material by starting the first electric push rod to move the fixed block into contact with the raw material, avoiding the raw material from falling when entering the numerically controlled machine tool for processing, and ensuring the stability of feeding.

[0004] However, the feeding structure cannot automatically fix both sides of the raw material during the feeding process. When the clamping plate is loosened and the raw material falls onto the upper end of the positioning seat, the user still needs to drive two groups of electric push rods to move the clamping plate to fix both sides of the raw material, and it cannot directly fix the raw material when it comes into contact with the positioning seat more quickly, thus reducing the use effect of the device. In view of this, we propose a machine tool convenient for stable feeding. Content of the Utility Model

[0005] The purpose of the utility model is to provide a machine tool convenient for stable feeding to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A machine tool convenient for stable feeding, including a machine tool body. A feeding device is arranged inside the machine tool body. A positioning seat is arranged above the feeding device. A positioning structure is arranged inside the positioning seat. The positioning structure includes:

[0007] A bottom plate, the bottom plate is slidably connected to the inner wall of the positioning seat. A cavity is opened inside the positioning seat. Two groups of positioning cylinders penetrate through the inner wall of the cavity. A sliding rod is slidably connected inside the positioning cylinder. The upper end of the sliding rod is fixedly connected to the lower end of the bottom plate;

[0008] A slider, the slider is slidably connected to both sides of the inner wall of the cavity. One end of a moving rod is fixedly installed on the side wall of the slider. The other end of the moving rod penetrates through the side wall of the positioning seat and is fixedly installed with a positioning plate. Connecting blocks are fixedly installed on both sides of the bottom plate. The other end of the connecting block penetrates through the inner wall of the cavity and is hinged to one end of a connecting rod. The other end of the connecting rod is hinged to the lower end of the slider. A return spring is arranged on the surface of the moving rod. A limiting structure is arranged inside the slider.

[0009] Preferably, the limiting structure includes a notch formed in the upper end of the slider. A limiting spring is fixedly installed on the inner wall of the notch. A sliding plate is fixedly installed at the upper end of the limiting spring. A limiting block is fixedly installed at the upper end of the sliding plate. Limiting grooves are formed on both sides of the inner wall of the cavity.

[0010] Preferably, a clamping rod penetrates through the inner wall of the limiting groove. A pressing plate is fixedly installed at the upper end of the clamping rod. A pressing spring is fixedly installed at the lower end of the pressing plate. The lower end of the pressing spring is fixedly connected to the upper end of the positioning seat.

[0012] Preferably, openings adapted to the movement tracks of the connecting blocks are formed on both sides of the positioning seat.

[0013] Preferably, the limiting groove and the limiting block are adapted to each other.

[0014] Compared with the prior art, the present utility model provides a machine tool facilitating stable feeding, having the following beneficial effects:

[0015] 1. The machine tool facilitating stable feeding is provided with a positioning structure, thus facilitating automatic positioning and fixing of both sides of the raw material after it falls onto the upper end of the positioning seat. When the raw material falls onto the middle of the bottom plate, the bottom plate will move downward. At this time, the bottom plate moves inside the positioning cylinder through two groups of sliding rods at its lower end. When the bottom plate moves, it will drive the connecting blocks on its side wall to move, thereby driving two groups of sliders to move relatively inward, so that two groups of moving rods drive the positioning plate to move to clamp and fix both sides of the raw material, thus making the feeding inside the machine tool more stable.

[0016] 2. The machine tool facilitating stable feeding is provided with a limiting structure, thus facilitating secondary limiting and fixing of the positioning plate. The movement of the slider drives the positioning plate to move to fix both sides of the raw material. At the same time, when the slider moves to a certain position, the limiting block is no longer squeezed by the inner wall of the cavity. At this time, the limiting block moves upward under the elastic force of the limiting spring at its lower end to engage with the limiting groove, so that the positioning plate can tightly adhere to the side wall of the raw material, further improving the stability of the device.

Specific embodiments

[0023] As Figures 1-5 shown, the present utility model provides a technical solution: a machine tool facilitating stable feeding, including a machine tool body 1, a feeding device 2 is arranged inside the machine tool body 1, a positioning seat 5 is arranged at the upper end of the feeding device 2, a positioning structure 3 is arranged inside the positioning seat 5, the positioning structure 3 includes a bottom plate 31 slidably connected to the inner wall of the positioning seat 5, a cavity 32 is opened inside the positioning seat 5, two groups of positioning cylinders 33 penetrate through the inner wall of the cavity 32, a sliding rod 34 is slidably connected inside the positioning cylinder 33, the upper end of the sliding rod 34 is fixedly connected to the lower end of the bottom plate 31, sliders 35 are slidably connected to both sides of the inner wall of the cavity 32, one end of a moving rod 36 is fixedly installed on the side wall of the slider 35, the other end of the moving rod 36 penetrates through the side wall of the positioning seat 5 and is fixedly installed with a positioning plate 37, connection blocks 38 are fixedly installed on both sides of the bottom plate 31, the other end of the connection block 38 penetrates through the inner wall of the cavity 32 and is hinged to one end of a connecting rod 39, the other end of the connecting rod 39 is hinged to the lower end of the slider 35, a return spring 310 is arranged on the surface of the moving rod 36, and a limiting structure 4 is arranged inside the slider 35.

[0024] Specifically, the positioning structure 3 of the technical solution of the present utility model includes: a bottom plate 31, a cavity 32, positioning cylinders 33, sliding rods 34, sliders 35, moving rods 36, positioning plates 37, connection blocks 38, connecting rods 39, and a return spring 310.

[0025] In an embodiment of the present utility model, a positioning structure 3 is provided to facilitate automatically positioning and fixing both sides of the raw material after it falls onto the upper end of the positioning seat 5. A feeding device 2 is provided to initially move the raw material and subsequently drive the positioning seat 5 to move. The feeding device 2 is an existing technology disclosed in the original application and will not be elaborated here. During use, the raw material falls onto the middle of the upper end of the positioning seat 5. At this time, when the raw material falls onto the middle of the bottom plate 31, the bottom plate 31 will move downward. At this time, the bottom plate 31 moves inside the positioning cylinder 33 through two sets of sliding rods 34 at its lower end. By providing the positioning cylinder 33, the sliding rods 34 can move more stably without deviation. And when the bottom plate 31 moves, it will also squeeze the return spring 310 to facilitate subsequent realignment.

[0026] And at this time, when the bottom plate 31 moves, it will drive the connecting block 38 on its side wall to move. Through the movement of the connecting block 38, the connecting rod 39 is driven to move. Through the movement of the connecting rod 39, two sets of sliders 35 hinged to it move relatively inward, so that the moving rod 36 on the side wall of the slider 35 drives the positioning plate 37 to move to clamp and fix both sides of the raw material, making the feeding into the machine tool body 1 more stable.

[0027] By providing a limiting structure 4, it is convenient to perform secondary limiting and fixing on the positioning plate 37. Through the movement of the slider 35, the positioning plate 37 is driven to move to fix both sides of the raw material. At the same time, when the slider 35 moves to a certain position, the limiting block 44 inside it is no longer squeezed by the inner wall of the cavity 32. At this time, the limiting block 44 moves upward under the elastic force of the limiting spring 42 and the sliding plate 43 at its lower end to engage with the limiting groove 45, so that the positioning plate 37 can tightly adhere to the side wall of the raw material, further improving the stability of the device.

[0028] During subsequent use, the user can press down the pressing plate 47 so that the clamping rod 46 moves downward. At this time, the clamping rod 46 moves into contact with the limiting block 44 and makes it enter the notch 41, thereby releasing the limit of the slider 35 and enabling it to return to the original position, thus improving the use effect of the device.

[0029] Please continue to refer to Figures 1-5, the limiting structure 4 includes a notch 41 formed in the upper end of the slider 35. A limiting spring 42 is fixedly installed on the inner wall of the notch 41. The upper end of the limiting spring 42 is fixedly installed with a sliding plate 43. The upper end of the sliding plate 43 is fixedly installed with a limiting block 44. Limiting grooves 45 are formed on both sides of the inner wall of the cavity 32. A clamping rod 46 penetrates through the inner wall of the limiting groove 45. The upper end of the clamping rod 46 is fixedly installed with a pressing plate 47. The lower end of the pressing plate 47 is fixedly installed with a pressing spring 48. The lower end of the pressing spring 48 is fixedly connected to the upper end of the positioning seat 5. One end of the reset spring 310 is fixedly connected to the side wall of the positioning cylinder 33, and the other end of the reset spring 310 is fixedly connected to the lower end of the bottom plate 31. Openings adapted to the moving trajectories of the connecting blocks 38 are formed on both sides of the positioning seat 5. The limiting groove 45 and the limiting block 44 are adapted to each other.

[0030] During operation, when the raw material falls on the middle of the upper end of the positioning seat 5, at this time, the bottom plate 31 moves inside the positioning cylinder 33 through the two sets of sliding rods 34 at its lower end. When the bottom plate 31 moves, it will also squeeze the reset spring 310 to facilitate subsequent return. When the bottom plate 31 moves, it will drive the connecting block 38 to move. The movement of the connecting block 38 drives the connecting rod 39 to move. The movement of the connecting rod 39 drives the two sets of sliders 35 hinged to it to move relatively inward, so that the moving rod 36 on the side wall of the slider 35 drives the positioning plate 37 to move to clamp and fix both sides of the raw material. At the same time, when the slider 35 moves to a certain position, the limiting block 44 inside it is no longer squeezed by the inner wall of the cavity 32. At this time, the limiting block 44 moves upward under the elastic force of the limiting spring 42 and the sliding plate 43 at its lower end to lock the limiting groove 45, so that the positioning plate 37 can closely adhere to the side wall of the raw material. When used subsequently, the user can press down the pressing plate 47 so that the clamping rod 46 moves downward. At this time, the clamping rod 46 moves into contact with the limiting block 44 and makes it enter the notch 41, thereby releasing the limit of the slider 35 and enabling it to return, thus improving the use effect of the device.

[0031] Generally speaking, the present invention has been described in detail above. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
