Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a grinding device for metal hot processing welding. Background Technique

[0002] Welding is a process in which the surface metal atoms of two or more workpieces are combined with each other to form a whole by heating, pressurizing, or both, with (or without) the use of filler materials. It is also called fusion welding or brazing, and is a manufacturing process and technology for joining metals or other thermoplastic materials by heating, high temperature or high pressure.

[0003] However, in the prior art, after the existing metal welding is completed, the weld seam is relatively rough and uneven. In order to improve the aesthetics, it is necessary to grind the weld seam to make it smooth and flat. When grinding metal parts, the existing method generally still uses manual grinding with an operator holding a grinding machine. However, after long-term work, the operator will feel tired, which will reduce the work efficiency and grinding accuracy, and thus affect the grinding quality. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art: when grinding metal parts, the existing method generally still uses manual grinding with an operator holding a grinding machine. However, after long-term work, the operator will feel tired, which will reduce the work efficiency and grinding accuracy, and thus affect the grinding quality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a grinding device for metal hot processing welding, including a grinding table, on the upper surface of which a table frame is fixed. A lead screw is rotatably penetrated through the table frame, and a motor is fixed on the side surface of the table frame, and the output end of the motor is fixedly connected with the lead screw. A track rod is slidably penetrated through the surface of the table frame, and connection blocks are fixed at both ends of the track rod. A first electric telescopic rod is fixed on one side of the connection block, and the first electric telescopic rod is fixedly connected with the table frame. A second electric telescopic rod is fixedly penetrated through the grinding table, and the telescopic end of the second electric telescopic rod is fixedly connected with the table frame. An upper clamping member is threadedly connected to the lead screw and a lower clamping member is slidably connected to the track rod. An insertion block is fixed on the surface of the lower clamping member, and the insertion block is inserted into the upper clamping member. A hand-held grinding machine is clamped and installed between the upper clamping member and the lower clamping member.

[0006] As a preferred implementation manner, third electric telescopic rods are fixedly connected to both sides of the grinding table, and an extrusion fixing plate is fixedly connected to one end of each third electric telescopic rod.

[0007] As a preferred implementation manner, a rubber pad is fixedly connected to the extrusion surface on one side of the extrusion fixing plate.

[0008] As a preferred embodiment, a storage groove is formed at the bottom position of the grinding table.

[0009] As a preferred embodiment, a partition board is fixedly connected to the surface of the storage groove, and the number of partition boards is set to be several.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0011] In the present utility model, when long-term grinding work needs to be carried out on the grinding table, the lower clamping member is adjusted by the contraction of the first electric telescopic rod to cooperate with the upper clamping member to clamp and fix the handheld grinding machine. The overall frame can be adjusted up and down by the telescopic movement of the second electric telescopic rod, ensuring that the grinding disc of the handheld grinding machine can closely adhere to the surface of the metal part to be ground. With the help of the lead screw and the motor, the started handheld grinding machine moves left and right to grind the metal part. By clamping the handheld grinding machine between the upper clamping member and the lower clamping member, the handheld grinding machine is adjusted up and down with the help of the second electric telescopic rod, and is adjusted left and right with the help of the lead screw and the motor, enabling the instrument to control the grinding activity of the handheld grinding machine instead of humans, effectively avoiding the influence of fatigue on work efficiency and grinding accuracy when the operator needs to work for a long time.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment 1

[0019] As Figures 1 - 3 shown, the present utility model provides a technical solution: a grinding device for metal hot working welding, including a grinding table 1. A table frame 2 is fixed on the upper surface of the grinding table 1, and a lead screw 3 is rotatably penetrated through the table frame 2. A motor 4 is fixed on the side of the table frame 2, and the output end of the motor 4 is fixedly connected to the lead screw 3. By driving the lead screw 3 to rotate through the motor 4, the handheld grinding machine 11 clamped and fixed by the upper clamping member 8 and the lower clamping member 9 can move left and right along the track rod 5. The track rod 5 is slidably penetrated through the surface of the table frame 2, and connection blocks are fixed at both ends of the track rod 5. A first electric telescopic rod 6 is fixed on one side of the connection block, and the first electric telescopic rod 6 is fixedly connected to the table frame 2. By contracting the first electric telescopic rod 6, the lower clamping member 9 is movably adjusted to cooperate with the upper clamping member 8 to facilitate clamping and fixing the handheld grinding machine 11. A second electric telescopic rod 7 is fixedly penetrated through the grinding table 1, and the telescopic end of the second electric telescopic rod 7 is fixedly connected to the table frame 2. By the telescopic movement of the second electric telescopic rod 7, the whole table frame 2 can be adjusted up and down, and then the position of the handheld grinding machine 11 is adjusted up and down to ensure that the grinding disc of the handheld grinding machine 11 can closely adhere to the surfaces of metal parts with different thicknesses to be ground, improving the practicability. The upper clamping member 8 is threadedly connected to the lead screw 3 and the lower clamping member 9 is slidably connected to the track rod 5, and an insertion block 10 is fixed on the surface of the lower clamping member 9, and the insertion block 10 is inserted into the upper clamping member 8. When the upper clamping member 8 and the lower clamping member 9 are closed to each other, they play a role in clamping the handheld grinding machine 11. At this time, the insertion block 10 will pass through the upper clamping member 8, increasing the connection relationship between the upper clamping member 8 and the lower clamping member 9 and ensuring that the upper clamping member 8 and the lower clamping member 9 can move together. A handheld grinding machine 11 is clamped and installed between the upper clamping member 8 and the lower clamping member 9.

[0020] Embodiment 2

[0021] As Figures 1 - 3As shown in the figure, three - way electric telescopic rods 12 are fixedly connected to both sides of the grinding table 1, and one end of each three - way electric telescopic rod 12 is fixedly connected to an extrusion fixing plate 13. The cooperation of the three - way electric telescopic rod 12 and the extrusion fixing plate 13 serves to clamp and fix the metal parts to be ground. A rubber pad is fixedly connected to one side extrusion surface of the extrusion fixing plate 13. The setting of the rubber pad will increase the friction force of the extrusion surface of the extrusion fixing plate 13, thereby improving the stability of the extrusion fixing plate 13 when fixing the metal parts. A storage groove 14 is opened at the bottom of the grinding table 1. The storage groove 14 is used to store the tools required during processing, facilitating access at any time. A partition plate 15 is fixedly connected to the surface of the storage groove 14, and the number of partition plates 15 is set to several. The partition plate 15 serves to partition the space, facilitating the classified placement of tools so that the operator can quickly find the tools needed.

[0022] Working principle:

[0023] As Figures 1 - 3 shown in the figure, when the present utility model is in use, when the user does not need to perform grinding work for a long time, the metal parts to be ground can be placed on the grinding table 1, and the three - way electric telescopic rod 12 is extended to drive the extrusion fixing plate 13 to move, so that the extrusion fixing plate 13 clamps and fixes the metal parts. Then, the hand - held grinding machine 11 is taken out from the partition plate 15 of the storage groove 14, and the user holds it to grind the metal parts.

[0024] When there are more metal parts to be ground, the workload is large, and long - term work is required, after taking out the hand - held grinding machine 11, its holding part is placed on the lower clamping part 9. Then, the first - way electric telescopic rod 6 is controlled to contract, driving the track rod 5 and the lower clamping part 9 to move upward, so that the insertion block 10 passes through the upper clamping part 8, and the upper clamping part 8 and the lower clamping part 9 clamp and fix the hand - held grinding machine 11. Then, the metal part is taken out and placed below the grinding disc of the hand - held grinding machine 11, and then it is fixed by the extrusion of the extrusion fixing plate 13. Then, the second - way electric telescopic rod 7 is contracted to move the hand - held grinding machine 11 downward, making its grinding disc contact with the metal part. Then, the motor 4 and the hand - held grinding machine 11 are started, and the motor 4 drives the lead screw 3 to rotate, thereby driving the upper clamping part 8, the lower clamping part 9 and the hand - held grinding machine 11 to move linearly along the track rod 5, so that the hand - held grinding machine 11 moves and grinds the weld of the metal part.

[0025] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
