Description

Technical Field

[0001] The present application relates to the technical field of workbenches, and in particular to a movable workbench. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. For machine production, it includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly and debugging, painting and packaging, etc. In existing mechanical processing, a workbench is needed to carry and process parts on the workbench.

[0003] The announcement number is CN204585176U, and the name is a movable lightweight workbench, which includes two parallel bases, a plurality of strip brackets and universal wheels. The base includes two parallel columns and an upper cross bar connecting the two columns. The upper cross bar is provided with a plurality of screw mounting holes at certain intervals. The universal wheels are provided at the bottom of the base. Rubber pads are attached to the surface of the strip brackets. The distance between adjacent strip brackets and the number of strip brackets can be conveniently adjusted according to actual needs. Compared with traditional flat-panel workbenches, the weight is greatly reduced, and it can be easily moved to avoid the inconvenience caused by multiple handling of equipment.

[0004] With respect to the above-mentioned related technologies, the inventors found that the workbench for carrying parts adopts universal wheels for carrying and moving, but the universal wheels on the workbench lack a shock-absorbing structure, and the workbench surface shakes greatly when moving.

During the movement, the part moves under the rolling of the rollers on the moving part. The vibration generated by the movement is transmitted to the turntable through the rollers. The vibration causes the slide on the turntable to slide vertically on the slide frame, and the vibration squeezes the damping rod to expand and contract. At the same time, the slide squeezes the spring on the slide frame to deform to absorb excess vibration. The elastic potential energy of the spring is absorbed by the expansion and contraction damping force of the damping rod, thereby reducing the vibration of the workbench when it moves.

[0032] By adopting the above technical scheme, during use, the part profile is placed horizontally on the pallet 24 of the workbench 2 on the upper side of the base frame 1, and then the workbench 2 is pushed to move under the support of the movable member 3. During the movement, it moves by rolling under the roller 33 on the movable member 3. The vibration generated by the movement is transmitted to the rotating frame 32 through the roller 33. The vibration causes the slide 31 on the rotating frame 32 to slide vertically on the slide frame 11, and the vibration squeezes the damping rod 34 to expand and contract and deform. At the same time, the slide 31 squeezes the spring 35 to deform on the slide frame 11 to absorb excess vibration. The elastic potential energy of the spring 35 is absorbed by the expansion and contraction damping force of the damping rod 34, thereby reducing the vibration of the workbench 2 during movement and maintaining the stability of the workpiece parts on the pallet 24 of the workbench 2.

[0033] Reference Figure 4 The workbench 2 includes a table frame 21, which is horizontally arranged just above the base frame 1, and a support plate 24 is horizontally fixed inside the table frame 21, and multiple partitions 25 are horizontally fixed on the top surface of the support plate 24, and rubber pads 26 are horizontally fixed on the top surfaces of the multiple partitions 25. A support plate 24 is horizontally fixed inside the table frame 21 for lifting and supporting parts and components. Multiple partitions 25 are horizontally arranged on the top surface of the support plate 24, and multiple partitions 25 are used to separate parts and components. Rubber pads 26 are horizontally fixed on the top surface of the partitions 25 to avoid direct contact with the workpiece in the later stage and cause damage to the workpiece. Multiple slide cylinders 22 are vertically fixed on the bottom surface of the table frame 21, and a screw barrel rack 23 is horizontally fixed in the middle of the bottom surface of the table frame 21. The slide cylinder 22 on the table frame 21 is vertically guided in the lifting direction, and the screw barrel rack 23 arranged in the middle of the table frame 21 is used for vertically threading the table frame 21 to vertically lift and lower the table frame 21 on the base frame 1.

[0034] Reference Figure 3 and Figure 4 , a plurality of vertical rods 12 are vertically fixed on the top surface of the base frame 1, and the vertical rods 12 are vertically slidably inserted in the slide cylinder 22. The vertical rods 12 on the base frame 1 slide vertically in the slide cylinder 22 of the table frame 21, and the guide table frame 21 is vertically raised and lowered on the base frame 1 to adjust the height of the supported parts. A rotating plate 13 is horizontally fixed in the middle of the base frame 1, and a screw rod 14 is vertically rotated and connected in the middle of the rotating plate 13, and the screw rod 14 is threadedly installed in the screw barrel frame 23. During use, the screw rod 14 on the rotating plate 13 is rotated, and the screw barrel frame 23 set in the middle of the table frame 21 is threadedly driven to slide vertically, thereby changing the height of the lifted workpiece.

[0035] Reference Figure 4 and Figure 5 A slide bar frame 27 is horizontally fixed on one side end surface of the table frame 21, and a lifting member 28 is arranged on the slide bar frame 27. The lifting member 28 includes a hole block 281, and the hole block 281 is horizontally slidably mounted on the slide bar frame 27, and a hanger 282 is vertically arranged on the top surface of the hole block 281.

The bottom end of the hanger 282 is rotatably connected to the top surface of the hole block 281, and two lifting ropes 283 are vertically symmetrically fixed on the top surface of the hanger 282. The hanger 282 rotatably connected to the hole block 281 deflects to switch the lifting angle, and the two lifting ropes 283 on the hanger 282 are used to lift the parts and workpieces. A screw barrel 284 is horizontally fixed to the bottom end of the lifting rope 283, and a clamping stud 285 is installed on the screw barrel 284 through a horizontal thread. A screw barrel 284 is fixed to the bottom end of the suspension rope 283, and a clamping stud 285 is threadedly installed in the screw barrel 284. The clamping stud 285 is used to clamp the extruded part for clamping the workpiece in the later stage.

[0036] The implementation principle of a movable workbench in an embodiment of the present application is as follows: during use, the part profile is horizontally placed on the support plate 24 of the workbench 2 on the upper side of the base frame 1, and then the workbench 2 is pushed to move under the support of the moving part 3. During the movement, it moves by rolling under the roller 33 on the moving part 3. The vibration generated by the movement is transmitted to the rotating frame 32 through the roller 33. The vibration causes the slide 31 on the rotating frame 32 to slide vertically on the slide frame 11, and the vibration squeezes the damping rod 34 to expand and contract and deform. At the same time, the slide 31 squeezes the spring 35 on the slide frame 11 to deform and absorb excess vibration. The elastic potential energy of the spring 35 is absorbed by the expansion and contraction damping force of the damping rod 34, thereby reducing the vibration of the workbench 2 when it moves.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
