Description

Technical Field

[0001] This utility model relates to the field of floating connection of electric spindle, and in particular to an anti-loosening locking device for floating connection of electric spindle. Background Technology

[0002] An electric spindle is typically a high-speed, precision functional component that directly integrates a machine tool spindle with an electric motor. Electric spindles are usually used with a floating connection, which allows the electric spindle to float in a certain direction. The floating connection of the electric spindle is usually installed and fixed using a locking device.

[0003] Application No. 202122523836.8 discloses a floating fixing mechanism for an electric spindle, including a Y-axis worktable. An electric spindle is connected to the Y-axis worktable via an electric spindle mounting seat. An axial protection component is connected to the Y-axis worktable via an electric spindle baffle. A chamfering tool is provided at the other end of the electric spindle. An elastic component is provided inside the axial protection component for axial displacement compensation and axial vibration absorption of the electric spindle. The axial protection component includes an anvil and a mounting component. The mounting component is sleeved on the electric spindle baffle. A positioning component for positioning is threaded to one end of the mounting component. An elastic spring is sleeved on the part of the mounting component located between the electric spindle baffle and the clamping nut. The mounting component includes a stepped shaft, which includes a first shaft end and a second shaft end. A spring is sleeved on the second shaft end. A phase ring is sleeved on the end of the electric spindle away from the chamfering tool. The electric spindle mounting seat and the electric spindle baffle are both connected to the Y-axis worktable via floating screws.

[0004] The system utilizes an axial protection component as a floating connection to enable a floating connection of the electric spindle. The axial protection component is located on the electric spindle baffle, allowing the stepped shaft on the axial protection component to slide on the electric spindle baffle for floating protection. A fixed base is used to install and fix the electric spindle, with the fixed base, baffle, and screws acting as locking devices in designated positions. However, vibrations typically occur during the use of the electric spindle and floating components, which are transmitted to the fixed base and baffle. This can cause the screws to loosen due to rotation, affecting the safety of the electric spindle and floating components. Therefore, it is necessary for the locking device of the electric spindle floating connection to provide anti-loosening protection for the screws on the fixed base and baffle. Utility Model Content

[0036] 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.

[0037] This utility model provides, for example Figure 1-3 The anti-loosening locking device for the floating connection of the electric spindle is shown.

[0038] Example 1: Includes an electric spindle 1, a fixed base 3, a baffle 4, and an anti-loosening mechanism 6. The fixed base 3 provides support for the electric spindle 1, facilitating its installation. The baffle 4 provides support for the stepped shaft, facilitating its installation. A worktable 2 is provided at the bottom of the electric spindle 1. The fixed base 3 is sleeved on the outside of the electric spindle 1. The baffle 4 is located on the side of the electric spindle 1. Screws 5 are threadedly connected to both the baffle 4 and the fixed base 3, facilitating the installation and removal of the baffle 4 and the fixed base 3 from the electric spindle 1. One end of the screw 5 is threadedly connected to the worktable 2. The anti-loosening mechanism 6 is located on the fixed base 3 and the baffle 4, and is used to limit the end of the screw 5.

[0039] Furthermore, the anti-loosening mechanism 6 includes a fixed plate 61, a limiting plate 62, and a limiting cylinder 63. The fixed plate 61 provides support for the limiting plate 62, facilitating its sliding. Adjacent fixed plates 61 on the baffle 4 are symmetrically arranged, and the stepped shaft is located in the middle of the baffle 4. Consequently, the vertical positions of the fixed plate 61 and the limiting plate 62 are located on the side of the stepped shaft. Thus, the upward movement of the limiting plate 62 is separated from the fixed plate 61 and is not affected by the stepped shaft. The limiting plate 62 effectively limits the top of the screw 5. To prevent screw 5 from shifting upwards on its own and to protect it from loosening, the limiting sleeve 63 covers and protects the end of screw 5, which helps to improve the vertical stability of the limiting plate 62. Multiple fixing plates 61 are fixedly connected to the fixing base 3 and the baffle 4 respectively. The top of the limiting plate 62 has a through groove, and the fixing plates 61 are slidably inserted into the inner cavity of the through groove. The limiting plate 62 is located on the top of screw 5, and the limiting sleeve 63 is fixedly connected to the bottom of the limiting plate 62. The limiting sleeve 63 is slidably sleeved on the end of screw 5.

[0040] Furthermore, the anti-loosening mechanism 6 also includes a positioning component and a support frame 610. The support frame 610 is beneficial for providing bottom support for the limiting plate 62, which helps to increase the stability of the limiting plate 62. The positioning component is located on the limiting plate 62 and is used to fix the limiting plate 62 to the fixing plate 61. The support frame 610 is fixedly sleeved on the outside of the fixing plate 61 and is located at the bottom of the limiting plate 62.

[0041] Specifically, the positioning components include a fixing frame 64, a mounting plate 65, a mounting slot, and a square frame. Figure 3The middle section is a cross-sectional schematic diagram of the fixed frame 64. The fixed frame 64 facilitates the sliding of the mounting plate 65 and provides support for the mounting plate 65. The mounting plate 65 helps to limit the relative position of the fixed frame 64 and the fixed plate 61, thereby facilitating the fixing of the limiting plate 62 and the fixed plate 61. The fixed frame 64 is fixedly connected to the top of the limiting plate 62. The mounting plate 65 is slidably inserted into the inner cavity of the fixed frame 64. The mounting groove is opened on the side of the fixed plate 61. The mounting plate 65 is slidably inserted into the inner cavity of the mounting groove. The square frame is fixedly embedded inside the fixed frame 64.

[0042] More specifically, the positioning assembly also includes an elastic steel sheet 66, a traction rod 67, and a guide. The elastic steel sheet 66 is arc-shaped and returns to its original shape after deformation. The elastic steel sheet 66 facilitates the movement of the mounting plate 65 and its return to its original position, allowing for repeated operations on the mounting plate 65. The traction rod 67 helps to pull the mounting plate 65, disengaging it from the fixed plate 61, allowing for the vertical removal of the limiting plate 62. The elastic steel sheet 66 is fixedly connected between the mounting plate 65 and the frame, and the traction rod... One end of rod 67 is fixedly connected to mounting plate 65. Traction rod 67 is slidably inserted into the inner cavity of the frame. Guide member is located on mounting plate 65. Guide member is used to horizontally guide the sliding of mounting plate 65. When it is necessary to remove limit plate 62, pull two traction rods 67 to pull mounting plate 65 horizontally. Then, mounting plate 65 squeezes elastic steel sheet 66, causing elastic steel sheet 66 to deform. Then mounting plate 65 separates from fixed plate 61. Limit plate 62 can be removed by vertically moving upward.

[0043] The floating connection component on the baffle 4 specifically includes an anvil and a mounting component. The mounting component is sleeved on the baffle 4. One end of the mounting component is threadedly connected to a positioning component for positioning. The part of the mounting component located between the baffle 4 and the clamping nut is fitted with an elastic component, a compression spring. The mounting component includes a stepped shaft, which includes a first shaft end and a second shaft end. The compression spring is sleeved on the second shaft end. The anvil is threadedly connected inside the mounting component and positioned by the first nut. The first shaft end is threadedly connected from right to left with a positioning component, a second nut, and a safety threaded cap. The compression spring is sleeved on the second shaft end. The end of the electric spindle 1 away from the chamfering tool is fitted with a phase ring. The phase ring is a ring structure with a notch and has bolt holes. The phase ring and the electric spindle 1 are connected by bolts and bolt holes threadedly. The end of the electric spindle 1 that abuts against the axial protection component is fitted with an anvil pad. The connection of the above specific structure is consistent with the prior art mentioned in the background art, and will not be described in detail here.

[0044] The floating connection of the electric spindle 1 is specifically implemented as follows: when the electric spindle 1 vibrates axially and presses against the anvil, the anvil transmits the vibration to the clamping nut, which then transmits the vibration to the compression spring. Under the action of the compression spring, the axial vibration gradually disappears. When the electric spindle 1 is subjected to abnormal axial force and produces a large axial displacement, the compression spring can be quickly compressed, allowing the electric spindle 1 to retreat in time and avoid damage to the chamfering tool. The design of the safety thread cap prevents the stepped shaft end from scratching the workers. The mounting part is positioned between the mounting part and the baffle 4 through the positioning part, the clamping nut, and the elastic component compression spring, ensuring that the electric spindle 1 will not rotate in a floating state and cause a safety accident. The phase ring is a ring structure with a notch, which facilitates the disassembly and assembly of the phase ring.

[0045] Example 2: Based on Example 1, the guide component includes a guide plate 68 and an anti-detachment plate 69. The guide plate 68 facilitates horizontal guidance of the sliding of the mounting plate 65, and the anti-detachment plate 69 helps to limit the movement position of the guide plate 68, thereby keeping the elastic steel sheet 66 in a position as described above. Figure 2 At the indicated position, the guide plate 68 is fixedly connected to the side of the mounting plate 65, and the top and bottom of the inner wall of the fixing frame 64 are provided with guide grooves that are compatible with the guide plate 68. The anti-detachment plate 69 is fixedly connected to the inner wall of the guide groove.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
