Description

Technical Field

[0001] This utility model relates to the field of roughness treatment equipment, specifically to a tooling suitable for machining surface roughness of rotary parts on a lathe. Background Technology

[0002] In the machining of rotary parts on a lathe, after the rotary parts are machined, there is still a problem of large roughness on the outer wall of the rotary parts. Therefore, it is necessary to use roughness treatment equipment to grind the outer wall of the rotary parts to achieve the purpose of reducing roughness.

[0003] Chinese patent discloses a fine sanding belt machine with application number CN202120579911.X. The fine sanding belt machine includes a horizontally arranged base and a support frame arranged on the upper surface of the base. The support frame and / or the base are provided with three sanding belt wheels arranged in a triangle in the same plane. Sanding belts are laid on the three sanding belt wheels. The sanding belt wheels include two moving sanding wheels and one fixed sanding belt wheel connected to a power source. The support frame and / or the sanding belt wheels are provided with air jets facing the sanding belt for spraying cold air.

[0004] Although the fine polishing belt sander can grind the outer wall of a lathe rotating part, it still has the following drawbacks: Since this application requires the use of a linear drive device to drive the fine polishing belt sander so that it comes into contact with the lathe rotating part, and the wall to be processed in the lathe rotating part is located in the vertical direction, after the vertical sanding belt section between the two moving grinding wheels is adjusted to the vertical position, the vertical sanding belt section is located in the middle of the guide rail. When the linear drive device drives the entire fine polishing belt sander close to the lathe rotating part, a long section of the guide rail is located in front of the vertical sanding belt section. The guide rail and the clamp of the lathe rotating part block each other, making it difficult for the vertical sanding belt to contact the lathe rotating part, and thus the grinding process cannot be achieved. Utility Model Content

[0005] This utility model aims to provide a tooling suitable for machining the surface roughness of rotary parts on a lathe, solving the problem in the prior art where the vertical sanding belt section is located in the middle of the guide rail, causing the guide rail to obstruct the contact between the vertical sanding belt section and the rotary parts on the lathe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model discloses a tooling for machining surface roughness of rotary parts on a lathe, comprising: a linear drive device, a mounting base, a rotary drive device, a first fixed pulley, a second fixed pulley, a movable pulley, a movable mounting frame, a sanding belt, and an extended mounting arm. The output end of the linear drive device is connected to the mounting base, and the rotary drive device is fixed on the mounting base. The output end of the rotary drive device is fixed to the first fixed pulley. An extended mounting arm extends from one side of the mounting base, and the second fixed pulley is mounted on the extended mounting arm. A movable pulley is disposed below the second fixed pulley. The movable pulley and the extended mounting arm are mounted through a movable mounting frame, which can move vertically relative to the extended mounting arm. The movable mounting frame is positioned on the extended mounting arm through a connecting mechanism. A sanding belt with a triangular structure is wrapped around the first fixed pulley, the second fixed pulley, and the movable pulley. The sanding belt between the second fixed pulley and the movable pulley is a vertical segment.

[0008] Preferably, the extended mounting arm has an L-shaped structure, and the extended mounting arm and the movable mounting frame form a U-shaped structure, with the opening of the U-shaped structure facing the lathe rotating parts.

[0009] Preferably, the connecting mechanism includes a connecting bolt and a connecting nut. The connecting bolt passes through the movable mounting bracket and the extended mounting arm. The extended mounting arm has a strip-shaped hole for the connecting bolt to pass through. The strip-shaped hole is located in the vertical direction. The connecting bolt is threaded with a connecting nut. The large end of the connecting bolt cooperates with the connecting nut to clamp the movable mounting bracket and the extended mounting arm.

[0010] Preferably, the connecting bolt passes through a pad, which is clamped by the large end of the connecting bolt and the extended mounting arm.

[0011] Preferably, a first wheel rod is mounted on the extended mounting arm, a second fixed pulley is rotatably mounted on the first wheel rod, and a second wheel rod is mounted on the movable mounting frame, with a movable pulley rotatably mounted on the second wheel rod.

[0012] Preferably, the edge of the movable pulley protrudes from the movable mounting bracket near the lathe rotating part, and the edge of the second fixed pulley protrudes from the extended mounting arm near the lathe rotating part.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this application, by setting a movable mounting bracket that can move vertically relative to the extended mounting arm, it is possible to accommodate sanding belts of different lengths. After the sanding belt wraps around the first fixed pulley, the second fixed pulley, and the movable pulley, adjusting the position of the movable mounting bracket moves the movable pulley, thereby tightening the sanding belt. This ensures that when the rotary drive device drives the first fixed pulley to rotate, it can drive the sanding belt to circulate among the first fixed pulley, the second fixed pulley, and the movable pulley, thus enabling the grinding of lathe rotating parts. Furthermore, the length of the sanding belt can be used as needed to adapt to the height of different lathe rotating parts, improving applicability. Finally, both the extended mounting arm and the movable mounting bracket extend towards the lathe rotating parts, allowing the vertical belt segment located between the second fixed pulley and the movable pulley to contact the lathe rotating parts. The extended mounting arm and the movable mounting bracket do not protrude from the vertical belt segment, thus preventing them from obstructing contact between the vertical belt segment and the lathe rotating parts.

[0015] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 4As shown, this utility model discloses a tooling for machining surface roughness of rotary parts on a lathe, including: a linear drive device (not shown), a mounting base 1, a rotary drive device 2, a first fixed pulley 3, a second fixed pulley 4, a movable pulley 5, a movable mounting frame 6, a sanding belt 7, and an extension mounting arm 8. The output end of the linear drive device is connected to the mounting base 1. The rotary drive device 2 is fixed on the mounting base 1. The output end of the rotary drive device 2 is fixed to the first fixed pulley 3. An extension mounting arm 8 extends from one side of the mounting base 1. The second fixed pulley 4 is mounted on the extension mounting arm 8. The movable pulley 5 is arranged below the second fixed pulley 4. The movable pulley 5 and the extension mounting arm 8 are connected by the movable mounting frame 6. The movable mounting frame 6 can move vertically relative to the extension mounting arm 8. The movable mounting frame 6 is positioned on the extension mounting arm 8 by a connecting mechanism 9. A sanding belt 7 is surrounded by the first fixed pulley 3, the second fixed pulley 4, and the movable pulley 5. The sanding belt 7 has a triangular structure. The sanding belt 7 located between the second fixed pulley 4 and the movable pulley 5 is a vertical belt segment.

[0023] The extended mounting arm 8 has an L-shaped structure, and the extended mounting arm 8 and the movable mounting frame 6 form a U-shaped structure, with the opening of the U-shaped structure facing the lathe rotating parts. The U-shaped structure formed by the extended mounting arm 8 and the movable mounting frame 6 creates a deformation space for the sanding belt 7 between the extended mounting arm 8 and the movable mounting frame 6 when the vertical belt segment is compressed and deformed.

[0024] The connecting mechanism 9 includes a connecting bolt 91 and a connecting nut 92. The connecting bolt 91 passes through the movable mounting bracket 6 and the extension mounting arm 8. The extension mounting arm 8 has a slotted hole for the connecting bolt 91 to pass through. The slotted hole is located in the vertical direction. The connecting bolt 91 is threadedly connected to the connecting nut 92. The large end of the connecting bolt 91 and the connecting nut 92 cooperate to clamp the movable mounting bracket 6 and the extension mounting arm 8. The design of the connecting bolt 91 and the connecting nut 92 enables the positioning of the movable mounting bracket 6 and the movable pulley 5.

[0025] The connecting bolt 91 passes through a pad 93, which is clamped by the large end of the connecting bolt 91 and the extended mounting arm 8. The pad 93 makes the connecting bolt 91 and the connecting nut 92 clamp the movable mounting bracket 6 and the extended mounting arm 8 more tightly.

[0026] A first wheel rod 80 is mounted on the extended mounting arm 8, and a second fixed pulley 4 is rotatably mounted on the first wheel rod 80. A second wheel rod 60 is mounted on the movable mounting frame 6, and a movable pulley 5 is rotatably mounted on the second wheel rod 60. This achieves the rotatable mounting of both the second fixed pulley 4 and the movable pulley 5.

[0027] The edge of the movable pulley 5 protrudes from the movable mounting bracket 6 near the rotating lathe part, and the edge of the second fixed pulley 4 protrudes from the extended mounting arm 8 near the rotating lathe part. This design ensures that the edge of the movable pulley 5 protrudes from the movable mounting bracket 6, and the edge of the second fixed pulley 4 protrudes from the extended mounting arm 8, thus providing a distance between the vertical belt segment and both the movable mounting bracket 6 and the extended mounting arm 8. This guarantees that the vertical belt segment can contact the rotating lathe part first, preventing the movable mounting bracket 6 and the extended mounting arm 8 from obstructing the vertical belt segment's contact with the rotating lathe part.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
