Description

Technical Field

[0001] This utility model relates to the field of CNC honing machine technology, specifically a CNC honing machine with protective function. Background Technology

[0002] The CNC honing machine is a fully closed-loop controlled CNC product that integrates high performance, high precision, high reliability and high safety. It is suitable for honing precision holes in parts such as engine cylinder blocks and cylinder liners. After processing, it can obtain high-quality geometric shapes and surface micro-textures, making it an ideal honing equipment for cylinder blocks, cylinder liners and other workpiece holes.

[0003] A search revealed a high-precision spherical CNC honing machine published in Chinese Patent No. CN216463899U. The key technical point is that it solves the problems of existing honing machines requiring cold water rinsing during the grinding process, where the cooling water rinsing may wash away some impurities that are not easy to recycle, and large amounts of cooling water are not conducive to drainage, making the honing machine impractical.

[0004] However, it has been found that the existing technology and the above solutions only have simple baffle protection or no protection at all. During processing, the protective door is easily vibrated and opens automatically, causing debris to fly around, which poses a safety hazard. In order to solve the problem of low protection performance and easy opening of the protective door due to vibration in the existing technology, which causes debris to fly around and poses a safety hazard, this application proposes to set up components such as clamps and blocks. By connecting the clamps and blocks, the protective door is firmly locked, which can prevent the protective door from opening automatically due to vibration, prevent debris from flying around, and improve the protection performance of the honing machine. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The existing technology mentioned above has shortcomings and defects, such as low protective performance, easy opening of the protective door due to vibration, resulting in the splashing of debris during processing, which poses a safety hazard.

[0006] This utility model discloses a CNC honing machine with protective function, including a protective door and a mounting block. The inner wall of the protective door is fixedly inlaid with tempered glass, and a clip is fixedly connected to the front of the protective door. The mounting block has a cavity inside, and a locking block is slidably connected to the inner wall of the cavity. A connecting pin is slidably connected to the inner wall of the locking block, and both ends of the connecting pin are fixedly connected to the inner wall of the cavity. A pressing rod is slidably connected to the inner wall of the mounting block, and the back of the pressing rod is fixedly connected to the front of the locking block. A connecting ring is fixedly connected to the outer surface of the pressing rod, and a spring is fixedly connected to the back of the connecting ring. The other end of the spring is fixedly connected to the inner wall of the mounting block.

[0007] Furthermore, a protective shell is fixedly connected to the back of the mounting block, a base is fixedly connected to the bottom of the protective shell, and a stop block is fixedly connected to the back of the protective door.

[0008] Furthermore, a connecting rod is fixedly connected to the upper surface of the protective shell, and a sliding groove is provided on the front side of the connecting rod.

[0009] Furthermore, the inner wall of the sliding groove is slidably connected with a sliding block and a top block, and the bottom surface of the sliding block is fixedly connected to the upper surface of the protective door.

[0010] Furthermore, a second spring is fixedly connected to the right side of the top block, and the right end of the second spring is fixedly connected to the inner wall of the sliding groove.

[0011] Furthermore, a connecting rod two is fixedly connected to the front of the protective shell, a sliding groove two is provided on the upper surface of the connecting rod two, a sliding block two is slidably connected to the inner wall of the sliding groove two, and the back of the sliding block two is fixedly connected to the front of the protective door.

[0012] Furthermore, a telescopic rod is fixedly connected to the inner top wall of the protective shell, and a honing head is fixedly installed at the bottom end of the telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model incorporates tempered glass, a locking mechanism, a locking block, a pressing rod, a connecting ring, and a spring. By moving the protective door, the locking mechanism moves to the cavity position, pushing open the locking block. The locking block then moves the pressing rod and the connecting ring, compressing the spring. Subsequently, under the action of the spring, the locking block locks the locking mechanism, preventing the protective door from opening while the machine is running. The tempered glass allows for easy observation of the internal situation while providing protection. When the door needs to be opened, the operator can press the pressing rod to unlock the protective door. This device prevents the protective door from opening while the machine is running and allows for one-button unlocking of the protective door.

[0015] 2. This utility model, by setting up components such as sliding block 1, top block, spring 2, stop block, and sliding block 2, allows the protective door to be moved. When the protective door is moved, the protective door drives sliding block 1 and sliding block 2 to slide inside the corresponding sliding groove 1 and sliding groove 2. Sliding block 1 contacts the top block, causing the top block to compress spring 2. At this time, spring 2 is in a compressed state. When the protective door is unlocked, the top block automatically pops open under the action of spring 2, thereby allowing the protective door to automatically pop open. The stop block installed on the back of the protective door limits the protective door and prevents it from falling off. Thus, this device can work with the pressing rod to allow the protective door to open automatically. Attached Figure Description
