Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and more specifically, it relates to a grinding tool magazine. Background Technology

[0002] Grinding is a surface modification technique. It generally refers to a processing method that uses a rough object (such as sandpaper containing high-hardness particles) to change the physical properties of a material surface through friction. Its main purpose is to obtain a specific surface roughness.

[0003] For polishing large objects, the relatively large force area makes it relatively easy to control the grinding process with tools through calibration, and the error tolerance is also relatively high. However, for small objects, especially the glass surface of small watches, it is necessary to grind the inner edge of the glass to form a concave shape. Due to the characteristics of the glass material and the size of the force area, the wear and tear of the grinding tools must be strictly controlled during the processing. If care is not taken, the glass can easily be damaged.

[0004] The current method of tool changing is still done manually, which requires people to constantly monitor the wear and tear of the tools and consumables, which is time-consuming and labor-intensive. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a grinding tool magazine that has the advantages of enabling precise tool changing operations, replacing manual operation, and providing a foundation for automatic tool changing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a grinding tool magazine, including a support platform, a conveying mechanism disposed on the support platform, and a plurality of tool holders disposed on the conveying mechanism, wherein tools are placed through the tool holders and the conveying mechanism is used to change and convey the tools.

[0007] The support platform has multiple fixed tool changing positions distributed on one side. The support platform is equipped with a correction mechanism for correcting the positional deviation of the tool holder. The correction mechanism corrects the moving tool holder to fall into the exact tool changing position.

[0008] Preferably, the conveying mechanism includes an active support shaft disposed on the support platform, a driven support shaft disposed on the support platform, and a conveying chain arranged around the active support shaft and the driven support shaft. Both the active support shaft and the driven support shaft are provided with gears that mesh with the conveying chain. A first driving member is provided on the support platform, which drives the active support shaft to rotate, thereby driving the conveying chain to move and the driven support shaft to rotate.

[0009] Preferably, a slide rail is provided on the surface of the support table. The tool holder is embedded in the conveyor chain, and pulleys are equipped at the bottom of the tool holder. The pulleys slide along the direction of the slide rail.

[0010] Preferably, the correction mechanism includes a support frame provided on the support table, a rotating shaft sleeved on the support frame, and a second driving member for driving the rotation of the rotating shaft. A plurality of abutting rollers are distributed on the rotating shaft. The tool holder at the corresponding tool change position is abutted by the abutting rollers to correct the deviation of the tool holder.

[0011] Preferably, a mating gear is provided on the rotating shaft, and a rack meshing with the mating gear is provided on the driving shaft of the second driving member. The rotation of the rotating shaft is driven by the meshing of the mating gear and the rack.

[0012] Preferably, the tool holder is arranged in a "C" shape. Claws for clamping the tool are provided at the top of the tool holder, and a groove for abutting against the correction mechanism is provided inside the tool holder.

[0013] In summary, the beneficial effects of the present utility model are as follows: The support table serves as a support member. A conveying mechanism is provided on the support table, and a plurality of tool holders are provided on the conveying mechanism. Tools are placed on the tool holders, and the tools are replaced and conveyed through the conveying mechanism, so as to facilitate the taking and placing of the tools. However, due to the deviation of the moving positions of the plurality of tool holders, the tool change process is not accurate. Therefore, by distributing a plurality of fixed tool change positions on one side of the support table, the moving tool holder is corrected by the correction mechanism to fall into the exact tool change position, so as to achieve accurate tool change operation, replace manual operation, and provide a setting basis for realizing automatic tool change.

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

[0021] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] A tool magazine for grinding, see Figures 1-3 It includes a support platform 1, a conveying mechanism 2 disposed on the support platform 1, and a plurality of tool holders 11 disposed on the conveying mechanism 2. Tools are placed through the tool holders 11 and the conveying mechanism 2 is used to change and convey the tools.

[0024] The support platform 1 has multiple fixed tool change positions 12 distributed on one side. The support platform 1 is equipped with a correction mechanism 3 for correcting the positional deviation of the tool holder 11. The correction mechanism 3 corrects the movement of the tool holder 11 so that it falls into the exact tool change position 12.

[0025] The support table 1 serves as a support member. A conveying mechanism 2 is provided on the support table 1, and a plurality of tool holders 11 are provided on the conveying mechanism 2. Tools are placed on the tool holders 11, and the tools are replaced and conveyed through the conveying mechanism 2, which facilitates the picking and taking of tools. However, due to the offset of the moving positions of the plurality of tool holders 11, the tool changing process is not precise. Therefore, a plurality of fixed tool changing positions 12 are distributed on one side of the support table 1, and the correction mechanism 3 is used to correct the moving tool holder 11 to fall into the exact tool changing position 12, thereby realizing precise tool changing operation, replacing manual operation, and providing a setting basis for automatic tool change.

[0026] Specifically, the conveying mechanism 2 includes a driving support shaft 21 provided on the support table 1, a driven support shaft 22 provided on the support table 1, and a conveying chain 23 disposed around the driving support shaft 21 and the driven support shaft 22. Gears meshing with the conveying chain 23 are provided on both the driving support shaft 21 and the driven support shaft 22. A first driving member 24 is provided on the support table 1, and the driving support shaft 21 is rotated by the first driving member 24, thereby driving the conveying chain 23 to move and the driven support shaft 22 to rotate.

[0027] In this embodiment, the first driving member 24 drives the driving support shaft 21 to rotate. The driving support shaft 21 and the driven support shaft 22 support and fix the conveying chain 23, thereby driving the conveying chain 23 to move and the driven support shaft 22 to rotate, and further driving the plurality of tool holders 11 on the conveying mechanism 2 to move in sequence.

[0028] Specifically, a slide rail is provided on the surface of the support table 1. The tool holder 11 is embedded in the conveying chain 23, and a pulley 13 is provided at the bottom of the tool holder 11. The pulley 13 slides along the direction of the slide rail.

[0029] Through the configuration of the slide rail and the slide rail, the stability of the conveyance of the tool holder 11 is further improved.

[0030] See Figure 2 Specifically, the tool holder 11 is provided in a "C" shape. A claw 14 for clamping the tool is provided at the top of the tool holder 11, and a groove 15 for abutting against the correction mechanism 3 is provided inside the tool holder 11.

[0031] By setting the tool holder 11 in a "C" shape, it is more convenient to embed the tool holder 11 in the conveying chain 23, and the groove 15 is used to cooperate with the correction mechanism 3, providing a setting basis for the correction mechanism 3 to correct the tool holder 11.

[0032] See Figure 4Specifically, the correction mechanism 3 includes a support frame 31 mounted on the support platform 1, a rotating shaft 32 sleeved on the support frame 31, and a second driving member 33 that drives the rotating shaft 32 to rotate. The rotating shaft 32 has a plurality of abutting rollers 34 distributed on it. The abutting rollers 34 abut against the tool holder 11 on the corresponding tool change position 12 to correct the misalignment of the tool holder 11.

[0033] Since the corresponding tool change position 12 is fixed, for example, this embodiment has 5 tool change positions 12, and thus 5 abutment rollers 34 are set accordingly. The rotating shaft 32 is driven to rotate by the second driving member 33, so that the abutment rollers 34 abut against the corresponding tool holder 11. The position on the tool holder 11 is corrected by the cooperation of the groove 15 on the tool holder 11 and the abutment rollers 34.

[0034] Specifically, a meshing gear is provided on the rotating shaft 32, and a rack that meshes with the meshing gear is provided on the drive shaft of the second driving member 33. The rotation shaft 32 is driven by the meshing of the meshing gear and the rack.

[0035] In this embodiment, the connection between the second drive component 33 and the rotating shaft 32 is completed by the meshing of the gear and rack.

[0036] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
