Description

Technical Field

[0001] The utility model relates to a grinding and polishing mechanism which can adjust the position according to the wear amount of the grinding wheel. Background Art

[0002] With the rapid development of industry, companies are placing higher demands on the performance and lifespan of mechanical products. In actual production, components are required not only to have high dimensional accuracy, but also to have surfaces that are smoother and more aesthetically pleasing. Traditionally, manual polishing is a process that can no longer meet the growing demands for quality and efficiency, making automated production increasingly important. However, manual polishing has certain drawbacks, including high labor intensity, increased production costs, and the inability to automatically and evenly polish components.

[0003] A large number of lock manufacturers in China have designed numerous grinding mechanisms centered around industrial robots to meet market demand for lock polishing. Lock polishing involves contouring and removing surface defects through grinding. Currently, over 70% of this process is accomplished using grinding wheels, with the remainder using belt grinding. During the grinding process, the grinding wheel size decreases as it wears out. Industrial robot polishing, therefore, requires constant debugging, making it cumbersome and unsuitable for mass production.

[0004] The upper end of the unloading device proposed in the existing patents such as "A grinding device for dial processing" can be used to place the processed dial, and the lower surface of the unloading device is provided with a loading box sealing plate structure, but the movable accuracy needs to be improved.

[0005] Robotic handheld workpiece grinding is an automated grinding method. However, existing grinding wheel grinding devices on the market cannot adapt to the changes in the grinding wheel and still require manual intervention in some processes, which lacks practicality and adaptability. Therefore, a grinding device with adjustable displacement is needed to improve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a grinding and polishing mechanism that can adjust the position according to the amount of grinding wheel wear. The grinding and polishing mechanism has a compact structure, which not only helps to avoid excessive grinding force, but also facilitates the adjustment of the grinding wheel position according to the amount of grinding wheel wear.

[0007] The technical solution of the utility model is: a grinding and polishing mechanism that can adjust its position according to the amount of wear of the grinding wheel, including a base plate, a motor mounting plate being connected to the base plate in a transverse sliding manner, a spring being installed transversely on the bottom surface of the motor mounting plate, one end of the spring being connected to a screw, one end of the base plate being rotatably connected to a screw rod through a fixed block, one end of the screw rod being fixed with a hand crank handle, and the other end of the screw rod being threadedly connected to the screw rod.

[0008] In this embodiment, transverse slide rails are respectively installed on both sides of the seat plate, and two sliding blocks connected to the motor mounting plate are provided on each transverse slide rail.

[0009] In this embodiment, a sliding cover is fixed to the bottom surface of the motor mounting plate, and the other end of the spring is connected to the sliding cover.

[0010] In this embodiment, a spring baffle is fixed to one end of the coil close to the spring, and one end of the spring is connected to the spring baffle.

[0011] In this embodiment, clamping blocks are fixed on both sides of the fixing block, the clamping blocks are fixedly connected to the seat plate, and the screw is arranged between the two clamping blocks.

[0012] In this embodiment, a fixing sleeve is installed on the end surface of the fixing block away from the spiral tube, one end of the screw rod passes through the fixing block and the fixing sleeve, and the screw rod is rotatably connected to the fixing sleeve.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] When the grinding force is too large, the spring can be used to cause the sliding cover to drive the motor on the motor mounting plate and the workpiece to produce a small displacement, thereby avoiding excessive grinding force; when the radius of the grinding wheel becomes smaller, the hand crank handle can be rotated to adjust it so that the grinding wheel is moved to the original radius to ensure the grinding depth.

[0018] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0019] refer to Figure 1 and Figure 2

[0020] A grinding and polishing mechanism capable of adjusting its position according to the amount of grinding wheel wear comprises a base plate 1, to which a motor mounting plate 2 is laterally slidably connected, allowing the grinding wheel's motor to be mounted on the motor mounting plate. A spring 3 is laterally mounted on the bottom surface of the motor mounting plate, one end of which is connected to a solenoid 4. One end of the base plate is rotatably connected to a screw 6 via a fixing block 5. One end of the screw is fixed with a hand crank 7, and the other end of the screw is threadedly connected to the solenoid. The screw is thus driven to rotate by the hand crank, driving the motor mounting plate to adjust the grinding wheel's position. Simultaneously, the spring can cause a small displacement between the motor on the motor mounting plate and the workpiece when the grinding force is too great, thus preventing excessive grinding force.

[0021] In this embodiment, in order to ensure that the grinder and polisher has horizontal displacement, transverse slide rails 8 are installed on both sides of the base plate, and two sliders 9 connected to the motor mounting plate are provided on the transverse slide rails. Due to the action of the sliders, the motor mounting plate drives the motor to move along the transverse slide rails when subjected to force, and the two sliders ensure the movement and stability of the motor mounting plate during the movement.

[0022] In this embodiment, in order to better achieve the connection between the spring and the motor mounting plate, a sliding cover 10 is fixed to the bottom surface of the motor mounting plate, and the other end of the spring is connected to the sliding cover.

[0023] In this embodiment, in order to achieve the connection between the coil and the spring, a spring baffle 11 is fixed to one end of the coil close to the spring, and one end of the spring is connected to the spring baffle.

[0024] In this embodiment, in order to realize the connection between the fixed block and the seat plate, clamping blocks 12 are fixed on both sides of the fixed block. The clamping blocks are fixedly connected to the seat plate, and the screw is arranged between the two clamping blocks so that the rotation process will not cause left and right deviation and affect the work.

[0025] In this embodiment, in order to realize the rotational connection between the screw and the fixed block, a fixed sleeve 13 is installed on the end face of the fixed block away from the spiral tube. One end of the screw passes through the fixed block and the fixed sleeve, and the screw and the fixed sleeve are rotationally connected, which together play a role in stabilizing the screw.

[0026] During grinding, the workpiece contacts the grinding wheel and generates a grinding force. When the grinding force is too large, due to the action of the spring, the sliding cover drives the motor on the motor mounting plate and the workpiece to produce a small displacement, thereby avoiding excessive grinding force. When the radius of the grinding wheel becomes smaller, the hand crank handle can be rotated to adjust it so that the grinding wheel is moved to the original radius to ensure the grinding depth. The screw is located between the two clamps, so that the rotation process will not produce left and right deviations and affect the work.

[0027] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).

[0028] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.

[0029] Any component provided by the present invention can be assembled from multiple separate components, or can be a separate component manufactured by an integral forming process.

[0030] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
