Description

Technical Field

[0001] This invention belongs to the field of cutting tool processing, and in particular relates to a cutting tool polishing device. Background Technology

[0002] When polishing tools, the polishing machine needs to move back and forth to polish them. This process generates dust, lint, and sand. Since there is a lot of dust, lint, and sand in the environment, it is easy for them to fall onto the polishing machine's chassis. Traditional polishing machine chassis use a linear slide rail slider, which is prone to accumulating dirt and is not resistant to dirt. This can cause the slider to become immobile, requiring frequent cleaning by staff, which not only increases labor costs but also affects production efficiency.

[0003] In addition, traditional tool holders require manual handling to pick up and put down the tool holders, and the tool holders need to be held by hand and placed under the polishing wheel of the polishing machine for polishing. Since the polishing machine is in a low-temperature environment when it is working, there is not only a risk of frostbite on the hands, but also a risk of accidental injury to the hands. Therefore, the production efficiency is low.

[0004] In addition, existing technologies require manual opening of the tool fixture to pick up and put in the tool, which is labor-intensive, has low production efficiency, and is not very practical.

[0005] In addition, when polishing tools, both the front and back sides need to be polished. However, existing polishing machines can only polish the tools clockwise or counterclockwise at a time. Therefore, in order to improve production efficiency, companies generally use two or more polishing machines to polish both sides. This results in a large footprint and high production costs. Summary of the Invention

[0006] In view of this, the present invention aims to provide a tool polishing device to solve at least one of the problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0008] A tool polishing device includes a polishing mechanism, a polishing machine chassis, a sliding bracket, and an airbag clamp. The polishing mechanism is mounted on the bottom of the polishing machine chassis. The sliding bracket is mounted on one side of the polishing machine chassis. The airbag clamp is mounted on the sliding bracket and is located below the hemostatic blade of the polishing mechanism.

[0009] Furthermore, the polishing machine's traveling chassis includes a base, a slide plate assembly, a chassis motor, a chassis reducer, a traveling assembly, and a support tube. The slide plate assembly is installed on top of the base, and the chassis motor is installed on top of the slide plate assembly. The output shaft of the chassis motor is installed to the input end of the chassis reducer, and the output shaft of the chassis reducer is connected to the traveling assembly. The traveling assembly is installed inside the slide plate assembly, and the support tube is installed at the bottom of the traveling assembly. The support tube is installed above the base.

[0010] Furthermore, the sliding bracket includes a bracket base sliding assembly, a positioning assembly, an adjustment assembly, and a pad assembly. The bottom of the bracket base is installed to the polishing machine's traveling chassis. The sliding assembly is slidably installed on the top of the bracket base. The positioning assembly is installed in the middle of the upper part of the sliding assembly. The adjustment assemblies are installed on both sides of the upper part of the sliding assembly. The pad assembly is installed on one side of the upper part of the sliding assembly.

[0011] Furthermore, the polishing mechanism is a PGJ type polishing machine.

[0012] Furthermore, the polishing mechanism includes a polishing frame, a polishing burr assembly, a coaxial spindle assembly, and a polishing drive assembly. The bottom of the polishing frame is mounted to the polishing machine chassis, and the polishing drive assembly is mounted on one side of the top of the polishing frame. One side of the polishing drive assembly is connected to one end of the coaxial spindle assembly, and the other end of the coaxial spindle assembly is mounted to the polishing burr assembly.

[0013] Compared with existing technologies, the tool polishing equipment of the present invention has the following advantages:

[0014] The tool polishing equipment described in this invention is suitable for polishing machine processing environments. It is dirt-resistant, not easily damaged, and does not require frequent cleaning by workers, reducing safety hazards and avoiding scratches on the tools, making it highly practical. By controlling the air lock valve to control the clamping or releasing of the tool, it reduces labor costs and improves work efficiency, making it highly practical. Only one machine is needed, and by setting two sets of polishing wheels rotating in opposite directions, it can achieve both forward and reverse polishing of the tool, which not only reduces the footprint but also lowers costs and improves production efficiency.

[0041] In a preferred embodiment of the present invention, the polishing machine chassis 2 includes a base 21, a slide plate assembly 22, a chassis motor 23, a chassis reducer 24, a walking assembly 25, and a support tube 26. The slide plate assembly 22 is installed on top of the base 21, and the chassis motor 23 is installed on top of the slide plate assembly 22. The output shaft of the chassis motor 23 is installed to the input end of the chassis reducer 24. The output shaft of the chassis reducer 24 is connected to the walking assembly 25. The walking assembly 25 is installed inside the slide plate assembly 22. The support tube 26 is installed at the bottom of the walking assembly 25 and is installed above the base 21.

[0042] This walking chassis structure is suitable for polishing machine processing environments, and it is dirt-resistant, not easily damaged, and does not require frequent cleaning by staff, which greatly reduces labor costs, improves production efficiency, and is highly practical.

[0043] In a preferred embodiment of the present invention, the base 21 is a cuboid structure, and a mounting plate 211 is connected to each of the four corners of the base 21. The mounting plate 211 can be an existing bolt plate, the purpose of which is to facilitate the installation of the base 21 to the tool processing station.

[0044] In a preferred embodiment of the present invention, the slide plate assembly 22 includes a first slide plate 221, a second slide plate 222, a first support plate 223, a second support plate 224, a movable plate 225, four movable upper pulleys 226, and four movable side pulleys 227. The first support plate 223 and the second support plate 224 are arranged parallel to each other above the base 21. The first slide plate 221 is installed above the first support plate 223, and the second slide plate 222 is installed above the second support plate 224. One end of the first slide plate 221 and the second slide plate 222 are slidably connected to the moving plate 225. A polishing mechanism 1 is installed on one side of the top of the moving plate 225, and a chassis motor 23 and a chassis reducer 24 are installed on the other side of the top of the moving plate 225. The output shaft of the chassis reducer 24 passes through the moving plate 225 and is connected to the walking assembly 25. A movable upper pulley 226 is installed at each of the four corners of the top of the moving plate 225, and a movable side pulley 227 is installed on one side of each movable upper pulley 226. In actual use, the slide plate assembly 22 can drive the polishing mechanism 1 to move back and forth under the drive of the chassis motor 23 and the chassis reducer 24, thereby achieving the purpose of polishing the tool.

[0045] In a preferred embodiment of the present invention, the first slide plate 221 is a cuboid structure, and a plurality of first mounting holes are evenly formed on the surface of the first slide plate 221. The first slide plate 221 is mounted to the first support plate 223 through the first mounting holes. A first slide rail block is installed at each of the front and rear ends of the first slide plate 221. The first slide plate 221 and the second slide plate 222 have the same structure. The first slide rail block is used to limit the front and rear ends of the moving plate 225.

[0046] In a preferred embodiment of the present invention, an arc-shaped groove is provided on the side of the first support plate 223, and the first support plate 223 and the second support plate 224 have the same structure. The purpose of the arc-shaped groove is to avoid affecting the movement of the movable side pulley 227, and to ensure that the movable side pulley 227 is located under the first slide plate 221 or the second slide plate 222, thereby preventing dust, sand and other particulate matter from affecting the movement of the movable side pulley 227.

[0047] In a preferred embodiment of the present invention, the width of the first slide plate 221 is greater than the width of the first support plate 223. The purpose of this arrangement is to facilitate the sliding of the movable side pulley 227 under the first slide plate 221, thereby preventing dust, sand and other particulate matter from falling on the side of the first support plate 223 and thus avoiding affecting the movement of the movable side pulley 227.

[0048] In a preferred embodiment of the present invention, the walking assembly 25 includes a walking gear 251 and a walking rack 252. The walking rack 252 is installed inside the first slide plate 221, and a support tube 26 is installed at the bottom of the walking rack 252. One side of the walking rack 252 meshes with the walking gear 251 for transmission. The walking gear 251 is installed on the output shaft of the chassis reducer 24. In actual use, the output shaft of the chassis reducer 24 is coaxially connected with the walking gear 251. The rotation of the output shaft of the chassis reducer 24 drives the walking gear 251 to rotate. Since the walking rack 252 is fixed to the support tube 26, the walking gear 251 moves linearly on the walking rack 252. The linear movement of the walking gear 251 on the walking rack 252 drives the chassis reducer 24 and the moving plate 225 connected to it to move linearly, thereby realizing the purpose of the polishing mechanism 1 moving back and forth.

[0049] In a preferred embodiment of the present invention, the cross-section of the support tube 26 is rectangular. In actual use, the size of the square tube can be selected according to the actual situation.

[0050] In a preferred embodiment of the present invention, the sliding bracket 3 includes a bracket base 31, a sliding component 32, a positioning component 33, an adjusting component 34, and a pad component 35. The bottom of the bracket base 31 is mounted to the polishing machine chassis 2. The sliding component 32 is slidably mounted on the top of the bracket base 31. The positioning component 33 is mounted on the upper middle part of the sliding component 32. The adjusting components 34 are mounted on both sides of the upper part of the sliding component 32. The pad component 35 is mounted on one side of the upper part of the sliding component 32.

[0051] This sliding bracket 3 saves labor costs and reduces safety hazards. It is equipped with a positioning component 33 and an adjustment component 34, which can fix and adjust the position of the airbag clamp 4. The pad component 35 can protect the tool from damage during polishing and avoid scratches on the tool. It is highly practical.

[0052] In a preferred embodiment of the present invention, the bracket base 31 includes two bracket uprights 311, two bracket inclined plates 312, two optical axis fixing plates 313, and two bracket optical axes 314. Sliding components 32 are slidably mounted above the two bracket optical axes 314. The two bracket optical axes 314 are arranged in parallel, and both ends of the two bracket optical axes 314 are respectively installed to the two optical axis fixing plates 313. One end of each of the two bracket inclined plates 312 is installed to one optical axis fixing plate 313, and the other end of each of the two bracket inclined plates 312 is installed to the two bracket uprights 311, which are arranged in parallel. In this embodiment, the bracket base 31 can be used to place the airbag clamp 4, replacing manual labor and saving labor costs.

[0053] In a preferred embodiment of the present invention, the sliding assembly 32 includes a sliding support plate 321, a sliding cylinder 322, and four roller units. The sliding cylinder 322 is installed in the middle of an optical axis fixing plate 313. The telescopic rod of the sliding cylinder 322 is connected to one side of the bottom of the sliding support plate 321. A positioning assembly 33, an adjustment assembly 34, and a pad assembly 35 are installed on the top of the sliding support plate 321.

The two sliding rollers 323 are installed between the two roller mounting parts 324, and a bracket optical shaft 314 passes between the two sliding rollers 323. In actual use, the two sliding rollers 323 slide on the bracket optical shaft 314. A clearance groove is opened at each of the four corners of the top of the sliding support plate 321 to make way for the sliding rollers 323.

[0055] In a preferred embodiment of the present invention, the positioning component 33 includes a clamp positioning plate 331 and two clamp positioning screws 332. A positioning elongated through hole 333 is respectively opened on both sides of the upper part of the clamp positioning plate 331. The clamp positioning plate 331 is installed to the sliding support plate 321 through the positioning elongated through hole 333. The clamp positioning plate 331 is also installed with two clamp positioning screws 332. The clamp positioning plate 331 fixes the airbag clamp 4 through the clamp positioning screws 332. In this embodiment, the purpose of setting the positioning elongated through hole 333 is not only to facilitate the fixing of the airbag clamp 4, but also to adjust the position of the airbag clamp 4. When it is necessary to place the airbag clamp 4, the operator puts the positioning hole of the airbag clamp 4 into the clamp positioning screw 332 to fix the airbag clamp 4.

[0056] In a preferred embodiment of the present invention, the adjustment assembly 34 includes two adjustment brackets 341 and two hook plates 342. The two adjustment brackets 341 are L-shaped and are symmetrically arranged on both sides of the top of the sliding support plate 321. Each adjustment bracket 341 has an adjustment through hole 343. A hook plate 342 is installed on one side of each adjustment bracket 341. The hook plate 342 is connected to the clamp optical axis rod of the airbag clamp 4. In this embodiment, the purpose of setting the adjustment through hole 343 and the hook plate 342 is not only to facilitate further fixing of the airbag clamp 4, but also to further adjust the position of the airbag clamp 4.

[0057] In a preferred embodiment of the present invention, the pad assembly 35 includes a tool pad 351, a support base plate 352, a pad support 353, and a pad retaining plate 354. Both support base plates 352 are mounted on one side above the sliding support plate 321, and the tops of the two support base plates 352 are mounted to the pad support 353. Two pad retaining plates 354 are respectively mounted on both sides of the top of the pad support 353. Both ends of the tool pad 351 are respectively engaged within the pad retaining plates 354. In this embodiment, the pad assembly 35 serves to support and protect the tool, preventing scratches from forming on the tool during polishing and affecting tool quality.

[0058] In a preferred embodiment of the present invention, the tool pad 351 is made of wood. The reason for choosing wood is to avoid scratching the tool to be polished by the tool pad 351.

[0059] In a preferred embodiment of the present invention, the airbag clamp 4 includes an airbag clamping plate assembly 41, an airlock valve 43, a knife clamping plate assembly 44, and a plurality of airbag bodies 42. The airlock valve 43 is installed on the top of the airbag clamping plate assembly 41. The air inlet of the airlock valve 43 is connected to an external air source pipeline, and the air outlet of the airlock valve 43 is connected to a plurality of airbag bodies 42 pipelines through a multi-port valve. The airbag bodies 42 are installed on one side of the interior of the airbag clamping plate assembly 41, and the knife clamping plate assembly 44 is installed on the other side of the interior of the airbag clamping plate assembly 41.

[0060] This airbag clamp 4 has a simple structure. By controlling the airlock valve 43, it controls the opening and closing of the airbag clamp assembly 41 and the tool clamp assembly 44, thereby achieving the purpose of clamping or releasing the tool, reducing labor costs, improving work efficiency, and being highly practical.

[0061] In a preferred embodiment of the present invention, the airbag clamp assembly 41 includes a first airbag clamp 411, a second airbag clamp 412, and two airbag tension springs 413. The first airbag clamp 411 and the second airbag clamp 412 are symmetrically arranged. An airlock valve 43 is installed above the first airbag clamp 411. The first airbag clamp 411 and the second airbag clamp 412 are connected on one side by the two airbag tension springs 413. A plurality of airbag bodies 42 are installed inside the first airbag clamp 411 and the second airbag clamp 412 near the airbag tension springs 413. A knife clamp assembly 44 is installed on the other side of the first airbag clamp 411 and the second airbag clamp 412. In this embodiment, the function of the airbag tension springs 413 is to open the first airbag clamp 411 and the second airbag clamp 412 near the knife when the airbag bodies 42 are deflated, thereby releasing the clamping of the knife.

[0062] In a preferred embodiment of the present invention, the airbag splint assembly 41 further includes four tension spring hangers 414, and the upper and lower ends of each airbag tension spring 413 are respectively installed to one side of the first airbag splint 411 and the second airbag splint 412 through a tension spring hanger 414.

[0063] In a preferred embodiment of the present invention, the airbag clamp assembly 41 further includes a clamp optical axis rod 415 and a plurality of clamp connecting pieces 416. A plurality of clamp connecting pieces 416 are equidistantly installed on the inner middle of the first airbag clamp 411 and the second airbag clamp 412. Each clamp connecting piece 416 is sleeved onto the clamp optical axis rod 415. In actual use, the clamp optical axis rod 415 facilitates the clamping of the airbag clamp 4 onto the sliding bracket 3. The clamp connecting piece 416 consists of two rotatable connecting pieces, which serve as hinges or pins. This allows one side of the first airbag clamp 411 and the second airbag clamp 412 to be in a clamped or open state when the airbag body 42 is inflated or deflated.

[0064] In a preferred embodiment of the present invention, two clamping positioning holes are provided above the first airbag clamp 411, and the first airbag clamp 411 and the second airbag clamp 412 have the same structure. In actual use, two clamping positioning holes are also provided on the second airbag clamp 412, and the clamping positioning holes of the first airbag clamp 411 and the second airbag clamp 412 are symmetrically arranged. The clamping positioning holes are used in conjunction with the clamping positioning screws 332. The operator can use a robotic arm to move the clamp onto the sliding bracket, align the clamping positioning holes with the clamping positioning screws 332, and thus install the airbag clamp 4 onto the sliding bracket 3.

[0065] In a preferred embodiment of the present invention, an optical axis pad is respectively fitted to both ends of the clamp optical axis rod 415. The purpose of the optical axis pad is to prevent the clamp optical axis rod 415 from detaching from the clamp connector 416.

[0066] In a preferred embodiment of the present invention, the tool clamping plate assembly 44 includes a first tool clamping plate 441, a second tool clamping plate 442, a first tool fixing plate 443, and a second tool fixing plate 444. The first tool clamping plate 441 and the second tool clamping plate 442 are symmetrically arranged. The first tool clamping plate 441 is connected to the first airbag clamping plate 411 at the top, and the first tool fixing plate 443 is installed below the first tool clamping plate 441. The second tool fixing plate 444 is installed above the second tool clamping plate 442. The first tool fixing plate 443 and the second tool fixing plate 444 are symmetrically arranged, and the second tool clamping plate 442 is connected to the second airbag clamping plate 412 at the bottom. The tool clamping plate assembly 44 is used to clamp the tool. In this embodiment, both the first tool fixing plate 443 and the second tool fixing plate 444 are equipped with long protrusions for better clamping of the tool. The material of the long protrusions can be rubber or other materials, as long as they can achieve the purpose of clamping the tool.

[0067] In a preferred embodiment of the present invention, the number of airbags 42 is at least two. In actual use, the number of airbags 42 can be determined according to the actual situation.

[0068] In this embodiment, the airlock valve 43 is existing technology. When the large orifice of the airlock valve 43 is inflated, the airlock valve 43 is in a locked state, and the gas in the airbag body 42 can only enter and not exit. In this way, the airbag clamping plate assembly 41, along with the tool clamping plate assembly 44, holds the tool to be polished. When the small orifice of the airlock valve 43 is inflated, the airlock valve 43 is in an open state, and the airbag body 42 can be deflated, thereby releasing the clamping of the tool.

[0069] In actual use, the airlock valve 43 is used to control the inflation and deflation of the airbag body 42. When the airbag body 42 deflates, the airbag clamping plate assembly 41 opens with the tool clamping plate assembly 44, thereby releasing the clamping of the tool. When the airbag body 42 inflates, the airbag body 42 expands, thereby causing the airbag clamping plate assembly 41 to clamp the tool with the tool clamping plate assembly 44.

[0070] In a preferred embodiment of the present invention, the polishing mechanism 1 is an existing polishing machine, and the polishing mechanism 1 is a PGJ type polishing machine.

[0071] In a preferred embodiment of the present invention, the polishing mechanism 1 includes a polishing frame 11, a polishing machine burr assembly 12, a coaxial spindle assembly 13, and a polishing drive assembly 14. The bottom of the polishing frame 11 is mounted to the polishing machine chassis 2. The polishing drive assembly 14 is mounted on one side of the top of the polishing frame 11. One side of the polishing drive assembly 14 is connected to one end of the coaxial spindle assembly 13. The other end of the coaxial spindle assembly 13 is mounted with the polishing machine burr assembly 12.

[0072] Traditional polishing machines require two machines to polish the cutting tools in both directions. This polishing mechanism only requires one machine. By setting two sets of polishing wheels that rotate in opposite directions, it can achieve both directions of tool polishing. This not only reduces the floor space required but also lowers costs and improves production efficiency.
