Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a mechanical processing workbench. Background Art

[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. Some of the mechanical parts inevitably need to be processed manually after being processed by the equipment. When performing fixed-point processing on some parts that cannot be processed by some equipment, workers often need to perform steps such as splicing, grinding, cutting, and wiping. Due to the limitation of the size of a single workbench, multiple workbenches are often required to be used in combination in factories. The combination method, combination procedure and structure of the existing workbenches are complex, and the stability of the combined workbench is low, which makes the combined workbench inconvenient to use.

[0003] The Chinese utility model patent (authorization announcement number: CN212170313U name: a workbench) includes a bracket, a table top and a clamping ring. The table top is supported on the bracket, and a slide groove is arranged on the table top. The slide groove is arranged in an arc shape, and the two ends of the slide groove are connected to the side edges of the table top. The clamping ring is arranged in an arc shape, and the clamping ring is arranged inside the slide groove, and can slide along the slide groove. Among them, when the side edges of the two workbenches are butted against each other, the slide grooves of the two workbenches are assembled into a circular structure, so that the clamping rings of the two workbenches can rotate in the same direction along the circular structure, and then slide from the slide groove where they are located to another slide groove, and realize the splicing and fixing between the two workbenches, so as to improve the structural stability of the workbenches after assembly, but it has the following specific defects: 1. It can only be used in a fixed place, and it requires multiple people to move it, which is very laborious; 2. Some mechanical processing workbenches need to be used in conjunction with other mechanical processing equipment, so the fixed height often brings inconvenience to use. Utility Model Content

[0024] like Figure 1, 2 As shown in Figure 4, a machining workbench comprises a table top 1, table legs are fixed at the four corners of the bottom of the table top 1, casters 2 are installed at the bottom of the table legs, and a backstop is also installed at the bottom of the table top 1, the backstop comprises a stud screw 3, a bearing seat 4 and a backstop plate 5, the stud screw 3 is rotatably installed at the bottom of the table top 1 through the bearing seat 4, the threads at both ends of the stud screw 3 have opposite rotation directions, corresponding nuts 6 are respectively screwed at both ends of the stud screw 3, a connecting rod 7 is hinged on the nut 6, the backstop plate 5 is hinged at one end of the connecting rod 7 away from the nut 6, a guide rail 8 is fixed at the bottom of the table top 1, the guide rail 8 extends along the axis of the stud screw 3, a slot is opened on the nut 6, the guide rail 8 is snapped into the slot, the machining workbench can be moved and turned by the casters 2, and when the workbench moves to the specified position, the stud screw 3 is rotated to press the backstop plate 5 against the ground, thereby locking the workbench, which is very flexible and convenient to use.

[0025] In this embodiment, if Figure 1-3 As shown, it also includes a foot cup 9, the screw of the foot cup 9 passes through the backstop plate 5, and a limit pin 10 is installed at one end of the screw passing through the backstop plate 5. A compressed spring 11 is sleeved on the screw located between the backstop plate 5 and the chassis of the foot cup 9. After the foot cup 9 is pressed against the ground, the backstop plate 5 continues to move downward to compress the spring 11, applying a pre-pressure to the foot cup 9, thereby locking the workbench to prevent the backstop plate 5 from pushing the table legs off the ground after contacting the ground, causing the table top 1 to tilt when the side of the table top 1 is subjected to force, thereby affecting the use of the workbench.

[0026] In this embodiment, if Figure 1 and 2 As shown, one end of the stud screw 3 extends outside the edge of the table top 1, and a rotating rod 12 is fixed to the stud screw 3 outside the edge of the table. The stud screw 3 can be turned more easily and labor-savingly through the rotating rod 12, reducing the labor intensity of workers.

The drawer 13 is used to store various spare parts or registration documents. Its specific purpose can be determined according to different usage conditions or processing occasions.

[0028] In this embodiment, if Figure 1 and 2As shown, the table leg includes a fixed cylinder 14 and a movable rod 15. The bottom of the fixed cylinder 14 is fixed to the bottom of the desktop 1, and the movable rod 15 is inserted into the fixed cylinder 14. A plurality of through holes 16 are opened on the fixed cylinder 14 along its axial centerline direction. A positioning pin 17 is installed at the insertion end of the movable rod 15. The positioning pin 17 is inserted into the corresponding through hole 16. By adjusting the effective length of the table leg, it is ensured that the machining workbench is used in conjunction with various machining equipment with height requirements. When the table leg is shortened, the stop plate 5 is first lowered, and then the positioning pin 17 in the through hole 16 is pulled out, and the movable rod 15 is received in the fixed cylinder 14 to a suitable position, and then the positioning pin 17 is reinserted into the corresponding through hole 16. When the table leg is extended, the table leg is first completely lifted off the ground to a suitable height through the stop plate 5, and then the positioning pin 17 is pulled out and the movable rod 15 falls to the ground. Then, after adjusting the movable rod 15 to a suitable position, the positioning pin 17 is reinserted into the corresponding through hole 16, and finally the table leg is lowered to the ground.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
