If the specific orientation changes, the directional indication will also change accordingly. In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0018] Unless otherwise specified, all components in this utility model can be purchased from the market.

[0019] Example 1 Following the above technical solutions, such as Figure 1 As shown, this embodiment provides a floating deburring tool holder, including a tool holder clamping part 1 and a deburring grinding head clamping part 2 that are coaxially connected from front to back; As a preferred option, the floating tool holder is made entirely of tool steel, which has sufficient rigidity and strength to meet the usage requirements, and its cost is lower than that of existing deburring tool holders.

[0020] The deburring grinding head clamping part 2 has a first mounting cavity with an open front end along the axial direction, and a compression spring 22 that can extend and retract along the axial direction of the deburring grinding head clamping part 2 is provided in the first mounting cavity. The deburring head clamping part 2 is also provided with a threaded hole in the radial direction. The threaded hole communicates with the first mounting cavity. A limiting screw 3 passes through the threaded hole. The limiting screw 3 can abut against the deburring head 5 passing through the first mounting cavity. The function of the limiting screw 3 is to limit the axial displacement of the deburring head 5 during the deburring process, and to ensure that the deburring head 5 will not fall off under extreme conditions, and that the axial displacement of the deburring head 5 will not exceed the maximum elastic compression provided by the compression spring 22.

[0021] Preferably, the clamping strength of the deburring head 5 can be ensured by adjusting the tightness of the limit screw 3. Specifically, the thread tightness can be adjusted according to the hardness and size of the burr. For example, when dealing with small burrs with high hardness, the number of turns of the limit screw 3 can be increased appropriately to limit the maximum axial displacement of the deburring head 5 and ensure that the spindle transmits the maximum axial strength to the deburring head 5. When encountering large burrs with lower hardness, the number of turns of the limit screw 3 can be reduced appropriately to increase the axial displacement of the deburring head 5.

[0022] As a preferred embodiment, the outer diameter of the deburring head clamping part 2 is 14mm larger than the outer diameter of the tool holder clamping part 1.

[0023] As a preferred embodiment, the outer diameter of the deburring grinding head clamping part 2 is 20mm and the length is 65mm.

[0024] As a preferred embodiment, the outer diameter of the tool holder clamping part 1 is 6mm and the length is 30mm.

[0025] As a preferred embodiment, the compression spring 22 has a free length of 32~34mm, a compression amount of ≥12mm, and a cross-sectional diameter of 4.5~5.5mm.

[0026] As a preferred embodiment, the horizontal distance between the axis of the threaded hole and the front end face of the deburring grinding head clamping part 2 is 12mm.

[0027] Example 2 This embodiment provides a machining deburring tool, including the machining deburring floating tool bar provided in Embodiment 1, and also includes a tool holder 4 disposed at the axial front end of the machining deburring floating tool bar and a deburring grinding head 5 passing through the machining deburring floating tool bar; The tool holder 4 has a second mounting cavity with an open front end along the axial direction, and the tool holder clamping part 1 passes through the second mounting cavity.

[0028] As a preferred embodiment, the tool holder 4 is provided with at least two radial limiting holes along the circumference. A limiting pin 6 is provided in the radial limiting hole to limit the axial movement of the tool holder clamping part 1. In this embodiment, the limiting pin 6 is a bolt, and the limiting pin 6 can be threadedly connected to the radial limiting hole.

[0029] The working process of this embodiment is as follows: Insert the deburring grinding head 5 into the machining deburring floating tool holder, with the rear end of the deburring grinding head 5 abutting against the compression spring 22. Insert the limiting screw 3 into the threaded hole, with the bottom end of the limiting screw 3 abutting against the side wall of the deburring grinding head 5. Adjust the tightening state of the limiting screw 3 appropriately according to the size and hardness of the burr to complete the installation of the deburring grinding head 5. Insert the tool holder clamping part 1 into the second mounting cavity in the tool holder, and insert the limiting pin 6 into the radial limiting hole to complete the limiting of the tool holder clamping part 1.

[0030] When the deburring grinding head 5 is in the initial clamping state, the compression spring 22 is in the compressed state. After being mounted on the machine, the spindle of the machining setting ensures a speed of about 2k. Since the deburring grinding head 5 has a certain degree of freedom in the axial direction, the compression spring 22 has a certain amount of axial extension and contraction. The deburring effect is achieved through the friction between the burr and the grinding head.

[0031] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0033] Furthermore, various different embodiments disclosed herein can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content of the utility model disclosed herein.
