Description

Technical Field

[0001] The utility model relates to the technical field of a power tool turret with a brake protection function, in particular to a power tool turret with a brake protection function. Background Art

[0002] The power turret is a general term for the automatic tool changing device and tool driving device of CNC machine tools. The power turret is often used in machining centers and is one of the core components of machining centers. Multiple tools can be installed on the power turret along the circumference of the tool disc. The tools are controlled by the program to realize the processes of tool changing, feeding, retracting, and rotary cutting.

[0003] A Chinese patent with announcement number CN214517652U discloses a power turret with a brake protection function. A brake buffer assembly is installed on one side of the turret body. The brake buffer assembly includes a connecting rod, a connecting plate, a bolt, a fixing plate, a positioning groove, a positioning block, a slide groove, a spring, a buffer block and a guide block. The brake buffer assembly plays a buffering role during the rotation of the connecting rod to prevent the power turret from shaking due to the connecting rod rotating too fast.

[0004] However, the above-mentioned patent provides a slide groove 207 at the bottom end of the connecting rod 201, and a spring 208 is embedded in the top inner side of the slide groove 207. Since only the spring is provided for buffering, the spring works very frequently, which reduces the service life of the spring. The embedded installation method makes it difficult for the user to replace the spring later, that is, not only the replacement frequency is high, but also the operation is complicated; at the same time, impurities flow out along the gap at the connection between the limit groove 301 and the limit plate 303, and the user needs to clean it manually, which also increases the burden on the user and brings certain adverse effects to people's use process. In order to solve the shortcomings of the prior art, we propose a power turret with a brake protection function. Utility Model Content

[0013] Beneficial Effects

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, by setting structures such as the damping ring and the height telescopic tube, compared with the shock absorbing effect of a single spring, the friction between the damping ring and the height telescopic tube is larger, so that the displacement caused by the spring rebound is smaller, on the one hand, the deformation distance of the spring is reduced, and on the other hand, the displacement of the cleaning rod due to the continuous amplitude generated by the spring is reduced, thereby increasing the service life of the spring and the cleaning time of the cleaning rod close to the annular groove. At the same time, the mounting frame and screws also facilitate the disassembly of the shock absorbing device and the replacement of the spring.

[0016] 2. In the utility model, the impurities flowing out of the annular groove can be cleaned by the connection rod and cleaning cotton and other structures, and the connection rod can be removed without affecting other operations of the turret body. At the same time, the cleaning cotton can be replaced after being dirty for a long time, which increases the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-Figure 4 As shown, a power turret with a brake protection function, the damping ring 8 and the height telescopic tube 6 are sleeved, the two ends of the spring 7 are detachably connected to the damping ring 8 and the upper end of the height telescopic tube 6 respectively, a connecting ring is provided between the cleaning rod 9 and the height telescopic tube 6, and the height telescopic tube 6 and the cleaning rod 9 are detachably connected via the connecting ring.

[0024] like Figure 1-Figure 4As shown, the ferrule 13 and the connecting rod 12 are detachably connected, the ferrule 13 is made of rubber, the height of the cleaning cotton 14 is greater than the distance between the limiting ring 3 and the connecting ring 4, and the cleaning cotton 14 is close to the edge of the connecting ring 4.

[0025] When the cleaning rod 9 rotates, it can scrape off impurities on the surface of the connecting ring 4. The impurities will flow out of the edge of the connecting ring 4 from the annular groove 17. The connecting rod 12 is inserted into the ring 13, and the cleaning cotton 14 is close to the edge of the connecting ring 4. During the rotation process, the impurities flowing out are absorbed. When the cleaning cotton 14 is dirty, it can be disassembled and replaced together with the connecting rod 12.

[0026] It should be noted that the utility model is a power turret with a brake protection function. When in use, the user fixes the fixing frame 2 on the turret body 1 through the mounting seat 11 and screws, and then fixes the mounting frame 5 and the fixing frame 2 together through the screws 10. The turret body 1 drives the two groups of fixing frames 2 to rotate, and through the elastic action of the spring 7, drives the height telescopic tube 6 to telescope up and down. Due to the large friction between the damping ring 8 and the height telescopic tube 6, the frequency and deformation of the telescopic height tube 6 are shortened. At the same time, the time that the cleaning rod 9 is close to the annular groove 17 is increased.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
