Description

Technical Field

[0001] This utility model relates to the field of workpiece broaching technology, specifically to a broach pull-out and insertion device. Background Technology

[0002] A broach is a high-efficiency, high-precision multi-tooth cutting tool used in broaching processes. The broach uses a series of progressively larger teeth to cut away layers of metal from the workpiece, thereby obtaining the desired shape and dimensions (see appendix). Figure 1 and attached Figure 2 (As shown). Broaches are generally divided into two main categories: internal broaches and external broaches, used for machining internal and external surfaces, respectively. In the current operation of vertical broaching machines, after broaching, the workpiece must be removed, the broach retracted, and then the broach manually pulled out of the broaching machine. The metal shavings must be cleaned off, the next workpiece loaded, and then the broach reinserted. This process is not only labor-intensive and inefficient, but also prone to damage to the broach or workpiece due to improper operation, affecting machining accuracy and the broach's lifespan. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a puller insertion and removal device that can pull up and insert the puller in a semi-automatic manner without the need for manual operation by the operator.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a pull-out insertion device for a puller, comprising:

[0005] An adsorption mechanism is provided on one side of the broach. The adsorption mechanism includes an adsorption element. When the broach and the adsorption element are close, the adsorption element can adsorb the broach and connect with it. Under the action of the broaching machine, the broach can detach from the adsorption element.

[0006] A telescopic mechanism is provided on the side of the adsorption mechanism away from the broach. The telescopic mechanism is connected to the adsorption mechanism and can drive the adsorption mechanism and the broach to move closer to the workpiece.

[0007] Furthermore, the adsorption mechanism includes a mounting sleeve connected to the telescopic mechanism. The mounting sleeve has an internal cavity, within which at least a portion of the adsorption element is accommodated. The cavity fixes the position of the adsorption element, enabling it to accurately adsorb the puller.

[0008] Furthermore, a spring is installed within the cavity, positioned on the side of the suction member near the telescopic mechanism. One end of the spring is connected to the inner wall of the cavity, and the other end is connected to the suction member. The spring provides a buffering effect when the suction mechanism moves downwards and contacts the pull blade.

[0009] Furthermore, a buffer is provided on the side of the adsorption component near the puller, and the buffer is fitted against the side of the adsorption component near the puller. The buffer prevents damage from impact when the adsorption component directly contacts the puller, thus providing a cushioning effect. The spring and buffer further buffer and protect the adsorption component upon contact with the puller, improving the service life of the adsorption mechanism.

[0010] Furthermore, the buffer element is a rubber pad.

[0011] Furthermore, a guide sleeve is provided on the side of the mounting sleeve near the puller. The guide sleeve has a through hole, including a first through hole. The inner diameter of the first through hole on the guide sleeve near the mounting sleeve is smaller than the inner diameter of the first through hole away from the mounting sleeve, and the inner diameter of the first through hole gradually decreases as it approaches the mounting sleeve. The first through hole provides a guiding function, causing the puller to move along the first through hole towards the mounting sleeve and be attracted and fixed by the strong magnet.

[0012] Furthermore, the through hole also includes a second through hole, which is located on the side of the first through hole near the mounting sleeve. The central axes of the first and second through holes coincide, and the diameter of the second through hole is equal to or slightly larger than the diameter of the broach. This ensures that the broach is fixed and does not wobble within the guide sleeve.

[0013] Furthermore, it also includes a fixing mechanism for fixing the telescopic mechanism and the adsorption mechanism; the fixing mechanism includes two columns, which are perpendicular to the upper surface of the worktable and fixedly connected to the upper surface of the worktable. A fixing plate is provided at the end of the column away from the worktable, and the fixing plate is fixedly connected to the column. The telescopic mechanism is fixedly connected to the fixing plate.

[0014] Furthermore, the telescopic mechanism includes a telescopic cylinder disposed on the lower surface of the fixed plate, wherein the telescopic rod of the telescopic cylinder is arranged parallel to the column and extends toward the workbench.

[0015] Furthermore, the adsorption element is a strong magnet.

[0016] The beneficial effects of this invention are: by setting up the adsorption mechanism and the telescopic mechanism, the puller is pulled up and inserted in a semi-automatic manner, eliminating the need for manual operation by the operator. This improves the convenience, efficiency, and safety of puller operation, and reduces labor intensity and potential risks. Furthermore, it has a simple structure, low manufacturing cost, and is easy to operate. Attached Figure Description

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] See appendix Figure 3-6 As shown, a puller insertion and removal device in this embodiment includes a fixing mechanism 2, a telescopic mechanism 3, and an adsorption mechanism 4. The adsorption mechanism 4 is used to connect with the puller 5 and moves up and down under the action of the telescopic mechanism 3. The fixing mechanism 2 is used to fix the telescopic mechanism 3 and the adsorption mechanism 4.

[0029] In some embodiments, the fixing mechanism 2 serves as the basic fixing component of the entire device, used to install the cylinder and other components, ensuring the stability of the device during operation. The fixing mechanism 2 includes two columns 21, which are perpendicularly arranged to the upper surface of the worktable 1 and fixedly connected to the upper surface of the worktable 1. A fixing plate 22 is provided at the end of the column 21 away from the worktable 1. The fixing plate 22 and the column 21 can be integrally connected, or they can be detachably connected by screws, bolts, or fixing rings 23. This application does not impose any limitations. As long as it can be ensured that the device will not shift or loosen during the removal of the puller 5, it is acceptable.

[0030] In some embodiments, the telescopic mechanism 3 includes a telescopic cylinder 31 disposed on the lower surface of the fixed plate 22. The telescopic rod 32 of the cylinder and the column 21 are arranged parallel to each other and extend towards the worktable 1. The cylinder is an SC50×250 model, characterized by its compact structure and high reliability, and can provide a smooth and controllable pull-out force to ensure that the broach 5 is smoothly detached from the broaching machine 7 and placed into the broaching machine fixture 7. An adsorption mechanism 4 is provided at one end of the telescopic rod 32. Under the action of the telescopic rod 32, the adsorption mechanism 4 moves closer to the broach 5 and can adsorb and fix the broach 5. The drive mechanism also includes a reversing valve for opening or closing the telescopic cylinder 31.

[0031] See appendix Figure 6 and 7As shown, in some embodiments, the adsorption mechanism 4 includes a mounting sleeve 41, which is mounted on the cylinder telescopic rod 32. The mounting sleeve 41 has an internal cavity containing a spring 42 and an adsorption element 43. The spring 42 is positioned between the mounting sleeve 41 and the adsorption element 43, providing a buffering effect when the adsorption mechanism 4 moves downwards and contacts the puller 5. The adsorption element 43 is a strong magnet, also known as neodymium iron boron magnet (NdFeB), a high-performance permanent magnet material. It is composed of neodymium (Nd), iron (Fe), and boron (B), possessing extremely high magnetic energy product and coercivity, making it one of the strongest permanent magnet materials currently available. The magnetic energy product of neodymium iron boron magnets is typically between 300-500 kJ / m². 3 The value is significantly higher than that of other common magnetic materials (such as ferrite magnets and AlNiCo magnets). The suction element 43 is used to firmly attract and fix the puller 5.

[0032] In some embodiments, a buffer is provided on the side of the adsorption member 43 near the puller 5. The buffer serves to prevent damage caused by impact when the adsorption member 43 comes into direct contact with the puller 5. The buffer is a rubber pad 44. The combination of the spring 42 and the rubber pad 44 buffers and protects the adsorption member 43 at the moment of contact with the puller 5, thereby improving the service life of the adsorption mechanism 4.

[0033] In some embodiments, a guide sleeve 45 is provided on the side of the mounting sleeve 41 near the puller 5. The guide sleeve 45 has a through hole, including a first through hole 46. The inner diameter of the first through hole 46 of the guide sleeve 45 near one end of the mounting sleeve 41 is smaller than the inner diameter of the first through hole 46 away from the mounting sleeve 41, and the inner diameter of the first through hole 46 gradually decreases as it approaches one end of the mounting sleeve 41. The first through hole 46 provides a guiding function, allowing the puller 5 to move along the first through hole 46 towards the mounting sleeve and be attracted and fixed by the suction member 43.

[0034] In some embodiments, the through hole further includes a second through hole 47, which is disposed on the side of the first through hole 46 near the mounting sleeve. The central axes of the first through hole 46 and the second through hole 47 coincide, and the diameter of the second through hole 47 is equal to or slightly larger than the diameter of the broach 5, ensuring that the broach 5 is fixed and does not wobble within the guide sleeve 45.

[0035] Working process: Place the workpiece 6 blank into the tooling slot of the broaching machine 7, and move the manual reversing valve to drive the telescopic mechanism 3 towards the worktable 1. The broach 5 connected to the telescopic mechanism 3 moves downward and then extends into the broaching machine tooling.

[0036] The broaching machine 7 is started to perform broaching. Under the action of the broaching machine 7, the broach 5 automatically breaks free from the attraction of the magnet and separates from the adsorption mechanism 4 to start broaching. After the processing is completed, the broaching machine 7 retracts the broach 5, and the broach 5 is pushed upward and moves closer to the adsorption component 43 through the guide sleeve 45, where it is adsorbed and fixed by the adsorption component 43.

[0037] Turn the manual reversing valve again to start the telescopic mechanism. The telescopic mechanism 3 pulls the broach 5 out of the broaching machine 7 and retracts it upwards, pulling the broach 5 out of the tooling slot on the broaching machine 7. Then, take out the processed workpiece 6 to complete the entire operation process.

[0038] The puller 5 is pulled up and inserted in a semi-automatic manner, eliminating the need for manual operation by the operator. This improves the convenience, efficiency, and safety of puller 5 operation, reducing labor intensity and potential risks. Furthermore, it has a simple structure, low manufacturing cost, and is easy to operate.
