[0003] Existing multi-directional milling devices for guide sleeve machining generate debris during the milling process, which easily splashes into the surrounding environment, causing pollution. This requires subsequent cleaning, increasing the workload of workers. Furthermore, the debris easily scatters into the surrounding environment, making cleaning more difficult and affecting work efficiency. Utility Model Content

[0006] Preferably, the splash-proof assembly includes a crossbar, a transparent plate, an internal slot, and a movable component.

[0008] Preferably, the movable component includes a U-shaped strip, an L-shaped rod, an overlap groove, and a fixing screw. The U-shaped strip is fixedly connected to the side wall of the fixing frame, and the L-shaped rod is fixedly connected to the side wall of the crossbar inside the U-shaped strip. An overlap groove is provided above the fixing frame at the position corresponding to the L-shaped rod. The fixing screw is threadedly connected between the U-shaped strip and the L-shaped rod.

[0010] Preferably, the cleaning assembly further includes a fixing block, an arc-shaped groove, a rotating shaft, a limiting rod, and a limiting block. A fixing block is fixedly connected to the inner side wall of the fixing frame. An arc-shaped groove is provided on the fixing block.

A limiting block is fixedly connected to the side wall of the fixing block and to one end of the limiting rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model is equipped with an anti-splash component. The guide sleeve to be processed is fixed to the fixing mechanism, and then the fixing screw is rotated to make it rotate away from the U-shaped bar and L-shaped bar. Under the action of gravity, the L-shaped bar moves down along the U-shaped bar. The downward movement of the L-shaped bar drives the crossbar to move down, and the downward movement of the crossbar drives the transparent plate to move down. After the crossbar moves and retracts into the built-in groove, the transparent plate moves and overlaps the top of the bottom plate. During the subsequent milling process of the guide sleeve, the fixed frame and the transparent plate can prevent the debris generated during the milling process from splashing into the surrounding environment. Moreover, during the milling process, the workers can observe the milling effect of the guide sleeve through the transparent plate.
[0013] 2. This utility model is equipped with a cleaning component. After the milled guide sleeve is removed from the fixing mechanism, the limiting rod is rotated away from the limiting block under the action of the rotating shaft. Then, the elastic corrugated tube is taken out from the inside of the arc groove. The operator then holds the vacuum head and moves it to align it with the base plate and the fixing mechanism. The movement of the vacuum head causes the elastic corrugated tube to move and deform. Then, the vacuum cleaner is started. Under the action of the vacuum cleaner, the debris on the base plate and the fixing mechanism enters the dust bin of the vacuum cleaner through the vacuum head and the elastic corrugated tube for collection. This makes it convenient for the operator to handle the debris generated during the milling process. Attached Figure Description

[0019] 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. Example 1
[0020] Please see Figure 1-4 The present invention provides the following technical solution: a multi-directional milling device for processing guide sleeves, including a base plate 4, a fixing mechanism 3 is provided above the base plate 4, a fixing frame 5 is fixedly connected above the base plate 4 and located outside the fixing mechanism 3, a milling mechanism 6 is provided on the fixing frame 5, a cleaning component 2 is provided on the side wall of the fixing frame 5, and anti-splash components 1 are provided above the base plate 4 and at both ends of the fixing frame 5.
[0021] Specifically, the splash guard assembly 1 includes a crossbar 11, a transparent plate 12, an internal groove 13, and a movable component 14. A transparent plate 12 is installed above the base plate 4 at both ends of the mounting frame 5. A crossbar 11 is fixedly connected between the two transparent plates 12. A movable component 14 is installed between one of the crossbars 11 and the mounting frame 5. An internal groove 13 is provided above the mounting frame 5 at a position corresponding to the crossbar 11.
[0022] By adopting the above technical solution, after the guide sleeve to be processed is fixed to the fixing mechanism 3, the moving part 14 drives the crossbar 11 to move down. The crossbar 11 moves down and drives the transparent plate 12 to move down. When the crossbar 11 moves into the built-in groove 13, the transparent plate 12 moves to overlap the top of the bottom plate 4. When the milling mechanism 6 is used to mill the guide sleeve, the fixed frame 5 and the transparent plate 12 can prevent the debris generated during the milling process from splashing into the surrounding environment. During the milling process, the workers can observe the milling effect of the guide sleeve through the transparent plate 12.
[0023] Specifically, several positioning blocks are fixedly connected to the lower part of the crossbar 11, and positioning grooves are provided on the side wall of the built-in groove 13 at the positions corresponding to the positioning blocks.
[0024] By adopting the above technical solution, the movement of the crossbar 11 drives the positioning block to move and insert into the positioning groove. With the cooperation of the positioning block and the positioning groove, the crossbar 11 can be positioned to ensure the stability of the crossbar 11 and thus ensure the stability of the transparent plate 12.
[0025] Specifically, the movable component 14 includes a U-shaped strip 141, an L-shaped rod 142, an overlap groove 143, and a fixing screw 144. The U-shaped strip 141 is fixedly connected to the side wall of the fixing frame 5, and the L-shaped rod 142 is fixedly connected to the side wall of the crossbar 11 inside the U-shaped strip 141. An overlap groove 143 is provided above the fixing frame 5 at the position corresponding to the L-shaped rod 142. The fixing screw 144 is threadedly connected between the U-shaped strip 141 and the L-shaped rod 142.
[0026] By adopting the above technical solution, when the transparent plate 12 is needed, the fixing screw 144 is rotated to make it rotate away from the U-shaped bar 141 and the L-shaped bar 142. Under the action of gravity, the L-shaped bar 142 moves down along the U-shaped bar 141. The downward movement of the L-shaped bar 142 drives the crossbar 11 to move down, and the downward movement of the crossbar 11 drives the transparent plate 12 to move down, which facilitates the movement operation of the transparent plate 12.
[0027] In this embodiment, the guide sleeve to be processed is fixed to the fixing mechanism 3, and then the fixing screw 144 is rotated to make it rotate away from the U-shaped bar 141 and the L-shaped bar 142. Under the action of gravity, the L-shaped bar 142 moves down along the U-shaped bar 141. The downward movement of the L-shaped bar 142 drives the crossbar 11 to move down, and the downward movement of the crossbar 11 drives the transparent plate 12 to move down. When the crossbar 11 moves into the built-in groove 13, the transparent plate 12 moves to overlap the top of the bottom plate 4. Then, the milling mechanism 6 is used to perform milling operation on the guide sleeve. At the same time, the fixing mechanism 3 drives the guide sleeve to rotate, which facilitates multi-directional milling operation on the guide sleeve. During the milling process, under the action of the fixing frame 5 and the transparent plate 12, the debris generated during the milling process can be prevented from splashing into the surrounding environment. During the milling process, the workers can observe the milling effect of the guide sleeve through the transparent plate 12. Example 2
[0028] The difference between this embodiment and embodiment 1 is that the cleaning component 2 includes a vacuum head 21, a vacuum cleaner 23, and an elastic bellows 24. The vacuum cleaner 23 is fixedly connected to the side wall of the fixing frame 5, one end of the vacuum cleaner 23 is fixedly connected to the elastic bellows 24, and one end of the elastic bellows 24 is fixedly connected to the vacuum head 21.
[0029] Specifically, the cleaning component 2 also includes a fixing block 22, an arc-shaped groove 25, a rotating shaft 26, a limiting rod 27, and a limiting block 28. A fixing block 22 is fixedly connected to the inner wall of the fixing frame 5. An arc-shaped groove 25 is formed on the fixing block 22. A rotating shaft 26 is rotatably connected to one end of the fixing block 22. A limiting rod 27 is fixedly connected to the outer wall of the rotating shaft 26. A limiting block 28 is fixedly connected to the side wall of the fixing block 22, specifically around one end of the limiting rod 27.
[0030] By adopting the above technical solution, when the vacuum head 21 and the flexible corrugated tube 24 are not needed, the flexible corrugated tube 24 is snapped into the arc groove 25, and the vacuum head 21 is then placed on top of the fixing block 22. Then, under the action of the rotating shaft 26, the limiting rod 27 is rotated and placed into the limiting block 28. The limiting rod 27 can be used to limit and fix the flexible corrugated tube 24, which is convenient for storing and placing the vacuum head 21 and the flexible corrugated tube 24.
[0031] In this embodiment, after removing the milled guide sleeve from the fixing mechanism 3, the limiting rod 27 is rotated away from the limiting block 28 under the action of the rotating shaft 26. Then, the elastic bellows 24 is taken out from the inside of the arc groove 25. The operator then holds the vacuum head 21 and moves it to align it with the base plate 4 and the fixing mechanism 3. The movement of the vacuum head 21 causes the elastic bellows 24 to move and deform. Then, the vacuum cleaner 23 is started. Under the action of the vacuum cleaner 23, the debris on the base plate 4 and the fixing mechanism 3 enters the dust bin inside the vacuum cleaner 23 through the vacuum head 21 and the elastic bellows 24 for collection, which facilitates the operator's handling of the debris generated during the milling process.
[0032] In this utility model, the vacuum cleaner 23 is a previously disclosed technology, and the selected model is HLY-20.
[0033] The structure and principle of the fixing mechanism 3, which consists of a rotary drive device, a rotating frame, an electric cylinder I, a lifting plate, a slide groove, a slider, a semi-circular clamping block, a linear actuator I, a moving groove, a moving block, an arc-shaped clamping plate, a linear actuator II, and a support frame, have been disclosed in Chinese Patent Application No. 202323481246.9, which discloses a multi-directional milling device for machining guide sleeves. Its working principle is as follows: a rotary drive device, which can be a servo motor, is installed on the base plate 4. A rotating frame is installed at the output end of the rotary drive device, and an electric cylinder I is installed on the rotating frame. The output end of the first actuator is equipped with a lifting plate, which has a slide groove. Two sliders are slidably connected in the slide groove, and semi-circular clamping blocks are installed on the sliders. The size of the semi-circular clamping blocks is adapted to the inner diameter of the guide sleeve. A linear actuator is installed in the slide groove. The linear actuator can be a double-headed hydraulic cylinder with two telescopic ends that can extend and retract synchronously. The oil inlet and outlet ends of the double-headed hydraulic cylinder are connected to the hydraulic station through connecting pipes. The output end of the linear actuator is connected to the slider. The rotating frame has two moving slots, which are arranged opposite each other. Moving blocks are slidably connected in the moving slots, and arc-shaped clamping plates are installed on the moving blocks. The inner arc surface of the clamping plate is adapted to the outer diameter of the guide sleeve. A second linear actuator is installed in the moving groove. The second linear actuator can be a hydraulic cylinder. The oil inlet and outlet of the hydraulic cylinder are connected to the hydraulic station through connecting pipes. The output end of the second linear actuator is connected to the moving block. When milling the guide sleeve, the hydraulic station applies pressure to the first linear actuator, causing it to drive the slider sliding in the groove to move outward. This causes the semi-circular clamping block on the slider to clamp and fix the inner wall of the guide sleeve. After fixing, the outer surface of the guide sleeve can be milled. After milling, the hydraulic station applies pressure to the second linear actuator. Force is applied to move the sliding block within the moving slot. The opposing moving block drives the arc-shaped clamping plate to fix the outer circular surface of the guide sleeve. After fixing, the linear actuator slides, so that the semi-circular clamping plate no longer presses and fixes the inner wall of the guide sleeve. At the same time, the electric cylinder drives the lifting plate to move down, so that the semi-circular clamping block moves down, without affecting the milling work of the milling device on the inner wall of the guide sleeve. During the milling process, the rotary drive device drives the rotating frame to rotate, so that the guide sleeve fixed on the rotating frame rotates, which facilitates milling work on different positions of the inner and outer circular surfaces of the guide sleeve.
[0034] The structure and principle of the milling mechanism 6, which consists of an electric cylinder 2, a lifting frame, a limiting hole, an electric slide table, a slide block, a motor, and a milling cutter, have been disclosed in a multi-directional milling device for guide sleeve processing disclosed in Chinese Patent Application No. 202323481246.9. Its working principle is as follows: an electric cylinder 2 is fixedly connected above a fixed frame 5. A lifting frame is installed at the output end of the electric cylinder 2. A limiting hole is provided on the fixed frame 5, and the lifting frame slides within the limiting hole. An electric slide table is installed on the lifting frame, and a slide block is installed at the output end of the electric slide table. A motor is installed below the slide block, and a milling cutter is installed at the output end of the motor. The electric cylinder 2 drives the lifting frame to move up and down, and the electric slide table on the lifting frame drives the slide block to move left and right. The lifting cylinder 2 can drive the milling cutter to move up, down, left, and right, thereby facilitating the milling of the guide sleeve using the milling cutter.
[0035] The working principle and usage process of this utility model are as follows: The guide sleeve to be processed is fixed to the fixing mechanism 3. Then, the fixing screw 144 is rotated, causing it to rotate away from the U-shaped strip 141 and the L-shaped rod 142. Under the action of gravity, the L-shaped rod 142 moves downward along the U-shaped strip 141. The downward movement of the L-shaped rod 142 drives the crossbar 11 to move downward, which in turn drives the transparent plate 12 to move downward. When the crossbar 11 moves and retracts into the built-in groove 13, the transparent plate 12 moves and overlaps above the bottom plate 4. Then, the milling mechanism 6 is used to mill the guide sleeve. Simultaneously, the fixing mechanism 3 drives the guide sleeve to rotate, facilitating multi-directional milling operations on the guide sleeve. During the milling process, the fixing frame 5 and the transparent plate 12 help prevent debris generated during milling. The debris splashes into the surrounding environment. During the milling process, the operator can observe the milling effect of the guide sleeve through the transparent plate 12. After the milling is completed, the milled guide sleeve is removed from the fixing mechanism 3. Under the action of the rotating shaft 26, the limiting rod 27 is rotated away from the limiting block 28. Then, the elastic bellows 24 is taken out from the arc groove 25. The operator then holds the vacuum head 21 and moves it to align it with the base plate 4 and the fixing mechanism 3. The movement of the vacuum head 21 causes the elastic bellows 24 to move and deform. Then, the vacuum cleaner 23 is started. Under the action of the vacuum cleaner 23, the debris on the base plate 4 and the fixing mechanism 3 enters the dust bin of the vacuum cleaner 23 through the vacuum head 21 and the elastic bellows 24 for collection, which facilitates the operator's handling of the debris generated during the milling process.
