Description

Technical Field

[0002] In the production process of seats, various metal parts of different shapes are required. After the metal parts have been stored for a long time, the outer surface of the metal parts must first be polished and rust removed.

[0003] The existing utility model patent, such as CN220217938U entitled "A Rust Removal and Grinding Machine," discloses a grinding machine, a movable frame, a connecting column, a controller, a rotating shaft housing, a threaded column, a wheel frame, a pulley, a clamping plate, and a grinding plate. The grinding machine has fixed blocks on both sides of its outer end face, which are fixedly connected to the grinding machine. Limiting holes are provided on both sides of the outer end face of the grinding machine. A threaded hole is provided on the upper end face of the movable frame, and the connecting column is threadedly connected to the upper end face of the movable frame through the threaded hole. A first handle is provided on the outer end face of the controller, and a second handle is provided in the connecting column. A limiting block is provided on the upper end face of the grinding plate, and the grinding plate is embedded and connected to a fixed slide rail through the limiting block.

[0004] However, this device is mainly designed for plate-shaped or regular-shaped metal parts. For metal components with curved, irregular, or cylindrical shapes commonly used in seat production, its fixed linear grinding method is difficult to fit the complex curved contours of the metal parts, which can easily create grinding dead corners and result in incomplete rust removal.

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding and rust removal device to solve the technical problem of existing rust removal and grinding devices being unable to perform rust removal and grinding on complex metal parts surfaces.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A grinding and rust removal device includes a worktable, a mounting frame on the worktable, a grinding component fixed on the mounting frame, a plurality of parallel support rods horizontally rotatable on the worktable, a limiting frame sliding along the axial direction of the plurality of support rods on the worktable, a plurality of parallel limiting rods vertically rotatable on the limiting frame, and a driving component on the worktable for driving the limiting frame to move toward or away from the grinding component.

[0007] The present invention is further configured such that: the grinding assembly includes a drive motor, a connecting rod and a wire wheel, the drive motor is fixed on the mounting bracket, the connecting rod is horizontally fixed on the output end of the drive motor, and the wire wheel is fixed on the end of the connecting rod away from the drive motor.

[0008] The present invention is further configured such that: two mounting plates are arranged opposite each other on the workbench, and a plurality of the supporting rotating rods are rotatably disposed between the two mounting plates.

[0009] The present invention is further configured such that: the supporting rotating rod includes a first shaft, a first bearing sleeve and a support sleeve, the first shaft passes horizontally through one of the mounting plates and is threadedly connected to the other mounting plate, the first bearing sleeve is fixedly sleeved on the first shaft and located between the two mounting plates, and the support sleeve is fixedly sleeved on the first bearing sleeve.

[0010] The present invention is further configured such that a plurality of supporting balls are rotatably provided on the side wall of the supporting sleeve.

[0012] The present invention is further configured such that a rubber sleeve is fixedly fitted on the limiting sleeve.

[0013] The present invention is further configured such that: the driving assembly includes a screw and a slide rod, the screw is horizontally rotatably disposed on one side of the worktable, the slide rod is parallel to the screw and fixed on the other side of the worktable, one end of the limiting frame is threaded onto the screw, and the other end is slidably disposed on the slide rod.

[0014] Compared to the beneficial effects achieved by existing technologies: This application relates to a grinding and rust removal device, mainly used for grinding and removing rust from metal parts used in furniture.

[0015] By setting several horizontally rotatable parallel support rods on the worktable, and cooperating with a axially sliding limit frame and several vertically rotatable parallel limit rods on it, a multi-directional collaborative metal part fixing and conveying system is constructed. This allows cylindrical, tubular, and other irregularly shaped metal parts to be simultaneously fed axially during grinding and rust removal, effectively avoiding the grinding dead angle problem caused by traditional single fixing methods.

This not only significantly improves the uniformity and integrity of the metal part surface treatment, but also effectively solves the problem of low efficiency in manual adjustment and positioning, effectively improving the work efficiency of metal part grinding and rust removal, while enhancing the adaptability to metal parts of different specifications.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example: Reference Figures 1-3 This application discloses a grinding and rust removal device, comprising a worktable 1, a mounting frame 2 on the worktable 1, and a grinding assembly fixedly mounted on the mounting frame 2. The grinding assembly includes a drive motor 4, a connecting rod 5, and a wire wheel 6. The drive motor 4 is fixedly mounted on the mounting frame 2, the connecting rod 5 is horizontally fixed to the output end of the drive motor 4, and the wire wheel 6 is fixed to the end of the connecting rod 5 opposite to the drive motor 4. The drive motor 4 drives the connecting rod 5 to rotate, which in turn drives the wire wheel 6 on the connecting rod 5 to rotate.

[0020] like Figure 2 and Figure 3 As shown, the workbench 1 is horizontally rotatably equipped with several parallel support rods. Two mounting plates 7 are positioned opposite each other on the workbench 1, and the support rods are rotatably positioned between the two mounting plates 7. Each support rod includes a first shaft 8, a first bearing sleeve 9, and a support sleeve 10. The first shaft 8 horizontally passes through one of the mounting plates 7 and is threadedly connected to the other mounting plate 7. One end of the first shaft 8 is threaded, allowing for threaded connection with the first shaft 8 by setting a nut on the other mounting plate 7. The first bearing sleeve 9 is fixedly fitted onto the first shaft 8 and located between the two mounting plates 7. The support sleeve 10 is fixedly fitted onto the first bearing sleeve 9. Figure 3 As shown, a plurality of support balls 11 are rotatably provided on the side wall of the support sleeve 10. This arrangement can effectively enable the support sleeve 10 to rotate between the two mounting plates 7 via the first bearing sleeve 9, and the plurality of support balls 11 on the support sleeve 10 can enable the metal parts located on the support sleeve 10 to move in multiple directions.

[0021] like Figure 2and Figure 3 As shown, the workbench 1 is equipped with a limiting frame 3 that slides axially along several supporting rotating rods. Several parallel limiting rotating rods are vertically rotatable on the limiting frame 3. Each limiting rotating rod includes a second shaft 12, a second bearing sleeve 13, and a limiting sleeve 14. The second shaft 12 is vertically inserted into the limiting frame 3, and one end of the second shaft 12 is threaded to one side of the limiting frame 3. The connection method of the second shaft 12 is the same as that of the second shaft 12. The second bearing sleeve 13 is fixedly sleeved on the second shaft 12, and the limiting sleeve 14 is fixedly sleeved on the second bearing sleeve 13. A rubber sleeve 15 is fixedly sleeved on the limiting sleeve 14. The setting of the second bearing sleeve 13 effectively enables the limiting rods to rotate. The rubber sleeve 15 on the limiting rods further increases the friction between the limiting rods and the metal parts, allowing the user to more smoothly move the pipe pile metal parts along their axial direction for grinding after the limiting rods abut against the tubular metal parts.

[0022] like Figure 1 and Figure 2 As shown, the worktable 1 is equipped with a drive assembly for moving the limiting frame 3 toward or away from the grinding assembly. The drive assembly includes a screw 16 and a slide rod 17. The screw 16 is horizontally rotatable on one side of the worktable 1, and the slide rod 17 is parallel to the screw 16 and fixed to the other side of the worktable 1. One end of the limiting frame 3 is threaded onto the screw 16, and the other end is slidably fitted onto the slide rod 17. By driving the screw 16 to rotate, the limiting frame 3 can be effectively moved along the screw 16 and slide rod 17, moving closer to or away from the wire wheel 6. The screw 16 can be driven by a motor or manually.

[0023] Working principle: During operation, the drive motor 4 is first started, driving the connecting rod 5 and the wire wheel 6 fixed at its end to rotate at high speed, forming the main power source for grinding and rust removal. Then, the tubular or rod-shaped metal parts to be processed are placed horizontally on several supporting rotating rods. The weight of the metal parts is borne by the support sleeve 10, and it is in point contact with the support balls 11 on the side wall of the support sleeve 10, allowing the metal parts to easily rotate circumferentially and make slight axial adjustments on the supporting rotating rods. Next, by manually or electrically rotating the screw 16, the limiting frame 3 is driven to move smoothly towards the metal parts along the screw 16 and the parallel slide rod 17 until the front ends of several vertically arranged limiting rotating rods on the limiting frame 3 are reached. All the rubber sleeves 15 are in reliable contact with the outer surface of the metal part and generate a certain clamping force. In this state, the operator only needs to gently push the metal part along the axis of the support rod, and the metal part can be fed axially under the low friction support of the support ball 11. When processing some thinner metal parts, under the reaction action of the grinding resistance of the wire wheel 6, the metal part will generate friction transmission with the support sleeve 10 and the limit sleeve 14, so that circumferential rotation is generated synchronously during the axial movement. Finally, the metal part can rotate on its own axis and pass through the grinding area at a uniform axial speed without the need for an additional drive source. When processing larger metal parts, manual control of the grinding position is required.

[0024] 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.
