Description

Technical Field

[0001] This utility model belongs to the field of hydraulic tool holder technology, specifically relating to a hydraulic tool holder for turning and boring. Background Technology

[0002] In tool holder systems, tool holders typically use spring collets, side-locking types, and tapered needle rollers to hold tools for internal turning, boring, and other machining operations. Most of these tool holders are rigidly fixed and cannot completely enclose the tool shank when fixed. This leads to vibrations in the tool during heavy-duty machining, which can damage the tool and reduce the machining accuracy of the parts. Therefore, we propose a hydraulic tool holder for turning and boring. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic tool holder for turning and boring, so as to solve the problem mentioned in the background art that most tool holders are rigidly fixed and cannot be completely wrapped when fixed to the tool bar. The tool will vibrate during heavy-load machining, which will cause certain damage to the tool and reduce the machining accuracy of the parts.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic tool holder for turning and boring, comprising a tool holder mounting end and a tool holder clamping end, one end of the tool holder clamping end being fixedly connected to the tool holder mounting end by brazing, an oil cavity being provided at the connection between the tool holder clamping end and the tool holder mounting end, an oil passage communicating with the oil cavity being provided inside the tool holder mounting end, a pressurizing component being provided on the tool holder mounting end, the pressurizing component being located below the internal cooling pipe, a sealing component being provided at one end of the pressurizing component, an internal cooling pipe being provided on the left side of the tool holder mounting end, the internal cooling pipe being connected to the left side of the tool holder mounting end by threads, two cooling channels being provided inside the tool holder mounting end, a universal nozzle being provided on the right side of the cooling channel, and the cooling channel communicating with the internal cooling pipe.

[0005] Preferably, a retaining ring is provided at the right end face of the internal cooling pipe, and sealant is evenly applied to the threaded connection of the internal cooling pipe.

[0006] Preferably, a plugging screw is provided at one end of the internal cooling pipe, and a plugging screw is also provided at one end of the internal oil passage.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] 1. By employing a hydraulic tool holder to fully enclose turning and milling tools, the clamping contact area is large, the force is uniform, the clamping force is large, and the rigidity is high. During turning or boring, it can effectively reduce tool vibration, extend tool life, and improve the machining accuracy of parts. The cross-section of the tool holder clamping end has a cooling device. During machining, coolant is sprayed out, which can more effectively cool the tool, ensure the accuracy of the tool holder, and improve the surface finish of the parts.

[0009] 2. By designing the hydraulic tool holder as a separate tool holder mounting end and clamping end, the separate structure can be manufactured separately; this design can meet the performance requirements of the product while reducing the processing difficulty. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a hydraulic tool holder solution for turning and boring: it includes a tool holder mounting end 1 and a tool holder clamping end 2. One end of the tool holder clamping end 2 is fixedly connected to the tool holder mounting end 1 by brazing. An oil cavity 3 is provided at the connection between the tool holder clamping end 2 and the tool holder mounting end 1. An oil passage 4 communicating with the oil cavity 3 is provided inside the tool holder mounting end 1. A pressure component 5 is provided on the tool holder mounting end 1. The pressure component 5 is located below the internal cooling pipe 6. A sealing component 10 is provided at one end of the pressure component 5. An internal cooling pipe 6 is provided on the left side of the tool holder mounting end 1. The internal cooling pipe 6 is connected to the left side of the tool holder mounting end 1 by threads. Two cooling channels 7 are provided inside the tool holder mounting end 1. A universal nozzle 8 is provided on the right side of the cooling channel 7. The cooling channel 7 is connected to the internal cooling pipe 6.

[0018] Specifically, an O-ring 9 is provided on the right end face of the internal cooling pipe 6, and sealant is evenly applied to the threaded connection of the internal cooling pipe 6.

[0019] Specifically, a plugging screw 11 is provided at one end of the internal cooling pipe 6, and a plugging screw 11 is also provided at one end of the internal oil passage 4.

[0020] In this embodiment, the pressurizing component 5 is used to increase the oil pressure in the sealed oil chamber 3 through the oil passage 4, thereby driving the inner hole of the tool holder clamping end 2 to contract radially, thus achieving the purpose of clamping the tool. The internal cooling pipe 6 is connected to the tool holder mounting end 1 by threads, and the threads are evenly coated with sealant. An O-ring 9 is used for sealing at the mating end face, which greatly improves the sealing effect. The coolant flows into the internal cooling pipe 6 through the spindle support rod, and then reaches the universal nozzle 8 through the cooling channel 7 and is sprayed out. When it is necessary to repair or replace certain components inside the oil chamber 3 and the internal cooling pipe 6, the plugging screw 11 can temporarily seal the oil chamber 3 and the internal cooling pipe 6 to prevent liquid leakage, thereby facilitating maintenance work. To ensure normal operation, the hydraulic tool holder is designed as a separate unit with a mounting end 1 and a clamping end 2, allowing for separate manufacturing of the components. This design meets product performance requirements while reducing machining difficulty. The hydraulic tool holder provides full-coverage clamping for turning, milling, and other cutting tools, resulting in a large clamping contact area, uniform force distribution, high clamping force, and high rigidity. This effectively reduces tool vibration, extends tool life, and improves part machining accuracy during turning or boring. The clamping end 2 has a cooling device; coolant is sprayed out during machining, further cooling the tool, ensuring tool holder accuracy, and improving the surface finish of the parts.
