Description

Technical Field

[0001] This utility model relates to the technical field of grinding auxiliary tools, and in particular to a workbench for grinding auxiliary metal parts. Background Technology

[0002] Copper doors are a type of metal door made primarily of copper (or copper alloys). They are commonly used in high-end residences, villas, hotels, and other similar locations. They offer advantages such as safety and durability. Compared to wooden doors, copper doors are more dignified and elegant, making them the ideal choice for upscale venues.

[0003] Currently, during the manufacturing process of copper doors, the components are connected by welding. Therefore, the welded joints of the copper door components (hereinafter referred to as workpieces) need to be polished during manufacturing. During polishing, workers use hand polishing tools (such as angle grinders) to polish the workpieces. Nowadays, in order to prevent the waste generated during polishing from affecting the workshop environment, the polishing of workpieces is usually carried out on a polishing workbench. The polishing workbench is a machine that can collect dust. When the workpiece is placed on the polishing workbench for polishing, most of the waste can be collected and vacuumed up, thus protecting the workshop environment to a certain extent. For reference, the prior art of a polishing platform disclosed in the authorized publication number CN105922140B on January 1, 2018 can be found.

[0004] However, while current sanding workbenches can vacuum up the dust generated during sanding, the spaced-out suction ports mean that a significant amount of dust remains on the workbench after sanding. This dust cannot be effectively removed between adjacent suction ports. For ease of cleaning, workers often manually feed the dust into the suction port after sanding, which, even with protective gloves, inevitably causes hand injuries.

[0005] Secondly, after the workpiece is polished, there will still be residual debris on the surface. Therefore, it is also necessary to perform preliminary cleaning of the workpiece surface (the workpiece is mainly transferred through the material basket, and if it is not cleaned, the debris will be scattered all over the workshop during the transfer process). Currently, the cleaning is also carried out on the polishing table. That is, the workpiece is generally initially cleaned by hand (or by holding a wiping cloth). The dust removal ability of the polishing workbench is used to remove the debris. After cleaning, the workpiece is placed in the material basket to wait for transfer. However, the polishing work is paused during the cleaning process. Therefore, the polishing work and the cleaning work affect each other, which will affect the production efficiency.

[0006] In summary, improvements need to be made to the existing auxiliary grinding worktable. Utility Model Content

[0063] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0064] like Figures 1-8 As shown, this embodiment provides a worktable for auxiliary metal part grinding, including:

[0065] The body 1 has a support platform 10 for placing metal parts. The support platform 10 is fixedly connected to one side of the body 1, and a support leg 11 is provided at the bottom of the support platform 10.

[0066] A vacuuming mechanism is installed on the main body 1;

[0067] The support platform 10 has several dust suction ports 100, and a first dust collection chamber 101 is formed inside the support platform 10. The inner wall of the first dust collection chamber 101 is inclined, and a second dust collection chamber 102 connected to the first dust collection chamber 101 is provided at the bottom of the machine body. A centrifugal fan 103 connected to the second dust collection chamber 102 is installed on the side wall of the machine body 1. A bag mounting plate 104 is also installed in the second dust collection chamber 102. The bag mounting plate 104 has several bag openings 105, and each bag opening 105 is provided with a bag (also called a filter bag).

[0068] In this embodiment, the body 1 is provided with a cleaning chamber 2. This embodiment also includes a movable dust removal device 3 provided on the body 1 and the support platform 10. The dust removal device 3 can enter or leave the cleaning chamber 2 when it moves.

[0069] The dust removal device 3 has a dust removal chamber 30 and a storage chamber 31 for placing metal parts. The dust removal device 3 is also provided with a dust removal port 32 that can face the support platform 10.

[0070] The suction branch consists of a first suction branch connected to the cleaning chamber 2, a second suction branch connected to the dust removal chamber 30, and a third suction branch connected to the suction port 100. The first dust collection chamber 101 and the second dust collection chamber 102 constitute the third suction branch in this embodiment.

[0071] When the dust removal device 3 moves onto the support platform 10, it can remove dust from the support platform 10 using the dust removal port 30. In this embodiment, the dust removal is achieved by sucking away impurities from the support platform through the dust removal port 32.

[0072] In this embodiment: the dust removal device 3 includes:

[0073] The dust removal frame 300 is mounted on the machine body 1 and can be moved by the driver 311. In this embodiment, the driver 311 consists of two hydraulic cylinders. The hydraulic cylinders are mounted on the back of the machine body 1 and spaced apart. The piston shaft 311a of the hydraulic cylinder extends into the cleaning chamber 2. The dust removal frame 300 is provided with two adjustment grooves 300a, and a first threaded hole 300b is provided in the adjustment groove 300a that penetrates the dust removal frame 300. The piston shaft 311a of the hydraulic cylinder is provided with a second threaded hole 300c corresponding to the first threaded hole 300b. When connecting, the piston shaft 311a of the hydraulic cylinder and the dust removal frame 300 can be fixed by bolts.

[0074] The storage cavity 31 is recessed at the top of the dust removal frame 300, and the bottom of the storage cavity 31 has dust discharge holes 310.

[0075] The dust removal chamber 30 is formed within the dust removal frame 300 and is spaced apart from the storage chamber 31, and is generally located below the storage chamber 31;

[0076] Dust removal port 32 is located at the bottom of dust removal frame 300 and is connected to dust removal chamber 30;

[0077] The cleaning chamber 2 is equipped with a support structure that supports the movement of the dust removal frame 300.

[0078] In this embodiment: the support structure includes:

[0079] The first suction body 41 and the second suction body 42 are arranged longitudinally at intervals, and one end is fixedly connected to the body 1. The first suction body 41 and the second suction body 42 are disposed in the cleaning chamber 2 and are fixedly connected to the inner wall of the cleaning chamber 2.

[0080] The first cavity 411 and the second cavity 422 are respectively formed in the first suction body 41 and the second suction body 42, and the two ends of the second cavity 422 are provided to penetrate the second suction body 42.

[0081] The slide rail 43 is fixedly connected to the inner wall of the cleaning chamber 2;

[0082] The dust removal frame 300 is equipped with a slider 44 that slides on the slide rail 43, and has a support port 45 for the first suction body 41 to move. The second suction body 42 can move within the dust removal chamber 30.

[0083] In this embodiment: the first suction body 41 includes:

[0084] The base plate 412 is fixedly connected to the body 1. In this embodiment, the base plate 412 is fixed to the inner wall of the cleaning chamber 2.

[0085] Side plates 413 are fixedly connected to the base plate 412 at intervals;

[0086] The bottom plate 412 and the side plate 413 form a dust collection area that communicates with the storage cavity 31. In other words, the top of the first dust collection body 41 is open. When the first dust collection body 41 slides into the support port 45, the first dust collection body is located at the bottom of the storage cavity 31. Therefore, the storage cavity 31 is connected to the dust collection area through the dust discharge hole 31.

[0087] refer to Figure 7 As shown, in this embodiment, the ends of the first suction body 41 and the second suction body that are away from the dust removal frame 300 are both designed with a narrow opening (taking the first suction body as an example, the width of the end of the first suction body that is away from the dust removal frame 300 is smaller than the width of the end that is close to the dust removal frame 300, so it is a narrow opening design), which makes it easy to connect to the first suction branch and the second suction branch respectively.

[0088] In this embodiment: the first suction branch includes a first suction chamber 51 formed inside the body 1 and connected to the first cavity 411, and a first vacuum cleaner 52 disposed at the air outlet of the first suction chamber 51. The body 1 is provided with a first mounting port 53 that connects the first suction chamber 51 and the cleaning chamber 2. The constricted end of the first suction body is installed at the first mounting port 53.

[0089] The second suction branch includes a second suction chamber 61 formed inside the body 1 and connected to the second cavity 422, and a second vacuum cleaner (not shown) provided at the air outlet of the second suction chamber 61. The body 1 is provided with a second mounting port 63 that connects the second suction chamber 61 and the cleaning chamber 2, and the constricted end of the second vacuum cleaner is installed at the second mounting port 63.

[0090] In this embodiment, both the first and second vacuum cleaners can be centrifugal fans.

[0091] In this embodiment: both the first dust suction chamber 51 and the second dust suction chamber 61 are provided with mounting plates 64, and the mounting plates 64 are provided with a plurality of mounting ports 640, and a dust removal bag 65 is fixedly connected to each mounting port 640.

[0092] In this embodiment, the body 1 is provided with several cleaning ports, and each cleaning port is fitted with a sealing plate 7 by bolts. Each cleaning port corresponds to the second dust collection chamber, the first dust suction chamber and the second dust suction chamber respectively. When cleaning is required, the second dust collection chamber, the first dust suction chamber and the second dust suction chamber can be cleaned by removing the sealing plate 7.

[0093] In this embodiment, a limiting plate 3000 is provided on the dust removal frame 300. The size of the limiting plate 300 is larger than the nozzle of the cleaning chamber, and a roller 3001 is installed on the limiting plate 3000. The machine body 1 is provided with a limiting groove 3002 corresponding to the roller 3001. The limiting groove 3002 allows the roller 3001 to enter. In this way, the limiting plate 3000 can fit in close to the machine body 1.

[0094] In this embodiment, to improve sealing, sealing rings can be provided on the support port 45, the opening of the dust removal chamber 30, the mating surface between the sealing plate and the machine body, and the limiting plate 3000. The sealing rings can be made of rubber. Since the first and second dust collection bodies need to move, the sealing rings at the corresponding positions also need to be lubricated.

[0095] In this embodiment, a control cabinet 1a is also installed on one side of the machine body 1. The start and stop of the hydraulic cylinder and each centrifugal fan can be controlled by the control cabinet 1a. A control board 1b connected to the control cabinet 1a is also provided on one side of the corresponding support platform 10. The control board 1b is provided with multiple buttons for controlling the hydraulic cylinder and each centrifugal fan. The control cabinet 1a is a mature existing technology, so it will not be described or shown in this embodiment.

[0096] In this embodiment, the body 1 is also provided with an air intake chamber 80 extending from the top. The air intake chamber 80 is connected to the cleaning chamber 2, and a filter screen is provided at the top opening of the air intake chamber 80.

[0097] refer to Figures 1-8 The operating principle of this embodiment is as follows:

[0098] 1. During grinding, the worker places the workpiece (i.e., the metal part in this utility model, the same below) on the support table and grinds the workpiece with a hand-held grinding device (such as an angle grinder). It is worth noting that some workpieces with a certain weight do not need to be fixed during grinding, as they generally will not move during grinding due to their own weight. However, some lighter workpieces need to be fixed during grinding. Fixing can be done by pressing down on the workpiece with a heavy object or by using existing clamps.

[0099] 2. Dust collection principle: During the grinding process, the centrifugal fan corresponding to the second dust collection chamber is activated. The centrifugal fan sucks up the dust generated during grinding through the second dust collection chamber, the first dust collection chamber, and the dust suction port. The dust is filtered by the cloth bag and left in the second dust collection chamber during dust collection.

[0100] 3. Dust Removal Principle: After grinding, the dust removal frame is moved out using a hydraulic cylinder. Simultaneously, the centrifugal fan corresponding to the second dust collection chamber is started. As the dust removal frame moves out, impurities on the support platform are sucked into the dust removal chamber through the dust removal port. Then, they enter the second dust collection chamber through the second cavity on the second dust collection body and are filtered by the dust collection bag inside the second dust collection chamber before being discharged, thus removing dust from the support platform. After the dust removal frame is moved out, the ground workpiece is placed into the receiving chamber. Then, the dust removal frame is moved into the cleaning chamber using a hydraulic cylinder, and the centrifugal fan corresponding to the first dust collection chamber is started again. When the centrifugal fan in the first dust collection chamber is started, gas enters from the air inlet chamber, passes through the cleaning chamber (i.e., the receiving chamber), and then enters the dust collection area of ​​the first dust collection body through the dust discharge port on the receiving chamber. It then enters the first dust collection chamber and is finally discharged by the centrifugal fan. During this process, impurities on the workpiece in the receiving chamber are carried away, thus completing the cleaning of the workpiece.

[0101] It should be noted that in actual operation, grinding efficiency needs to be considered. Therefore, after grinding the workpiece, the workpiece can be placed next to the support table. After grinding a batch of workpieces, the dust removal frame can be used to clean the support table. At the same time, a batch of workpieces can be moved to the storage cavity. During the movement, the dust removal frame can continuously clean the surface of the support table.

[0102] Example 2 differs from Example 1 in that:

[0103] like Figures 9-13As shown, in this embodiment, the bottom of the storage cavity 31 is not provided with a dust discharge hole 310. The support port 45 of this embodiment is provided on the side wall of the dust removal frame 300 and communicates with the storage cavity 31. Similar to Embodiment 1, the dust removal cavity 30 of this embodiment is also provided below the storage cavity 31.

[0104] In this embodiment, two guide rails 90 are fixedly connected between the walls of the receiving cavity 31, and a material frame 91 that can be controlled by the driving structure to reciprocate on the guide rails 90 is slidably connected on the guide rails 90.

[0105] The bottom of the material frame 91 and the bottom of the storage cavity 31 form an active area for the first vacuum cleaner 41 to move in, and several through holes 910 are provided at the bottom of the material frame 91. That is to say, when the first vacuum cleaner 41 enters from the support port 45, it is located below the material frame 91.

[0106] In this embodiment, one end of the through hole 910 (or opening) is provided with a trumpet-shaped structure. When viewed from the bottom inner wall of the material frame, the diameter of the through hole 910 gradually decreases and the through hole gradually becomes concave.

[0107] In this embodiment: the driving structure includes:

[0108] A crankshaft 93 is rotatably mounted on a dust collector frame 300 and is controlled to rotate by a motor 93c. In this embodiment, a drive chamber 930 is provided on the dust collector frame. The opening of the drive chamber 930 is detachably connected to a chamber cover 931 by bolts. For better heat dissipation, the chamber cover 931 may be provided with heat dissipation holes. The crankshaft in this embodiment consists of a U-shaped first shaft 93a and a second shaft 93b integrally formed at both ends of the first shaft 93a. The second shaft 93b can be rotatably connected to the cavity wall of the drive chamber 930. At least one second shaft 93b is connected to the motor shaft of the motor 93c, thereby realizing that the motor drives the crankshaft 93 to rotate. A motor base 93d may be provided in the drive chamber 930, and the motor may be mounted on the motor base 93d.

[0109] The collar 94 is sleeved on the outside of the crankshaft 93, which means that the collar 94 and the first shaft 93a are coaxially arranged and can rotate relative to each other axially.

[0110] A reciprocating drive shaft 95 is slidably mounted on a dust collector frame 300, and one end is fixedly connected to a material frame 91. The dust collector frame has a sliding cavity with two ends connecting the drive cavity and the storage cavity. The reciprocating drive shaft 95 passes through the sliding cavity and one end is fixedly connected to the material frame 91. In this embodiment, one end of the reciprocating drive shaft 95 is a connecting seat 95a. Threaded holes are distributed on the connecting seat 95a. Thus, the reciprocating drive shaft and the material frame can be installed by bolts by providing threaded holes with corresponding positions on the material frame.

[0111] The reciprocating drive shaft 95 and the collar 94 are both provided with hinge seats 96, and the hinge seats 96 are hinged to each other with connecting rods 97, that is, the two ends of the connecting rods 97 are rotatably connected to the hinge seats 96 through hinge shafts.

[0112] refer to Figures 9-13 When removing dust from a polished workpiece, the workpiece is placed in a material frame, and then the dust removal frame returns to the cleaning chamber. When the centrifugal fan in the first dust suction chamber is started, the crankshaft is rotated by the motor, and the crankshaft, through the connecting rod, controls the reciprocating drive shaft to move back and forth, thereby causing the material frame to move back and forth in the receiving chamber. During the reciprocating movement of the material frame, the frequent changes in the direction of movement of the material frame cause the workpiece inside the material frame to shake back and forth, and the waste on the workpiece can fall off, and then be discharged through the through hole and sucked away to complete the dust removal. In this embodiment, the material frame set by reciprocating movement can improve the dust removal efficiency of the workpiece.

[0113] Example 3 differs from Example 2 in that:

[0114] like Figure 14 As shown, the dust removal frame 300 is provided with a compensation frame 98, which has an air inlet area 980. The compensation frame 98 is installed at the opening of the receiving cavity 30. The length and width of the air inlet area of ​​the compensation frame 98 are both smaller than the length of the material frame. In this way, the compensation frame can cover the gap between the material frame and the receiving cavity.

[0115] like Figure 15 As shown, the compensation frame 98 consists of a first frame 981 and a second frame 982 in the shape of a U-shape. The first frame and the second frame are integrally formed. The first frame 981 is adapted to the opening of the receiving cavity, and the second frame 982 is spaced apart from the side wall of the receiving cavity. The gap between the second frame 982 and the cavity wall of the receiving cavity is the reciprocating range of the material frame. In this embodiment, the compensation frame covers the area between the material frame and the side wall of the receiving cavity, so that the gas entering from the air inlet cavity enters the material frame through the air inlet area and then exits through the through hole, thereby avoiding most of the gas from passing through the gap between the material frame and the receiving cavity, thereby improving the dust removal effect on the workpiece.

[0116] Compared with Embodiment 2, this embodiment allows the gas entering from the air inlet chamber to first pass through the air inlet area of ​​the compensation frame and enter the material frame. The airflow flowing through the material frame will blow away impurities on the workpiece, thereby improving the dust removal effect.

[0117] Example 4 differs from Example 3 in that:

[0118] like Figure 16As shown, in this embodiment, the compensation frame 98 can also be detachably connected to the dust removal frame. Specifically, the dust removal frame is provided with a U-shaped groove 99 (i.e., a groove in the shape of a U-shape). The U-shaped groove is coaxially arranged with the storage cavity. The bottom of the first frame of the compensation frame 98 near the outer edge is provided with a U-shaped limiting frame 990 (a frame in the shape of a U-shape) that can be inserted into the U-shaped groove. The compensation frame can be disassembled through the U-shaped limiting frame and the U-shaped groove. Therefore, when the compensation frame is severely deformed due to the impact of the workpiece, the compensation frame can be taken out and reshaped. Reshaping refers to the process of restoring the compensation frame to a shape similar to its original shape. If the material of the compensation frame is metal (or alloy), a rubber hammer can be used to tap the deformed area during reshaping to complete the reshaping.

[0119] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
