Description

Technical Field

[0001] The utility model relates to the technical field of workbenches, in particular to a multifunctional workbench for precision machining. Background Art

[0002] After searching, the Chinese patent publication number CN215616446U discloses a multifunctional auxiliary workbench for precision machining. Although the device limits the position of the fixture plate on the auxiliary workbench by using 2*D16 clamps when in use, and then uses 4*M10 clamps to efficiently fix it, the device only has a single function of quickly fixing the fixture plate when in use. The single function limits the application scope of the workbench. For workpieces that require multiple processing operations, it is necessary to frequently replace the workbench or use multiple workbenches, which increases the complexity and cost of the operation. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a multifunctional workbench for precision machining, which solves the problems raised in the background technology.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A multifunctional workbench for precision machining, comprising a bottom plate, on which a table top is mounted via a bracket;

[0006] The upper surface of the table board is paved with a work surface, a clamp is adsorbed on the work surface, a workpiece is clamped and fixed on the work surface by the clamp, and an LED backlight panel is paved on one side of the table board located on the work surface;

[0007] A main shaft is rotatably mounted on the bracket via a bearing, a worm wheel is arranged on the main shaft, a worm is arranged on the bracket via a square tube, a hand wheel is arranged at one end of the worm away from the square tube, and gears are arranged at both ends of the main shaft;

[0008] The bracket is plugged with a pillar, the pillar is in contact with the gear, a crossbeam is provided at the top of the pillar, fixed seats are provided at both ends of the crossbeam, and the table top is installed on the fixed seat through a limiting plate.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the worm and the worm wheel mesh with each other, and the worm is driven to rotate by the hand wheel, thereby driving the main shaft to rotate, so that the gears at both ends of the main shaft squeeze and push the pillar to rise and fall.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the worm and worm gear transmission mechanism has self-locking property. This means that without applying external force, the worm gear cannot rotate by itself, thus ensuring the stability and safety of the workbench during the lifting process.

[0013] Further, a sliding groove is provided on the limiting plate, a first locking bolt is installed on the fixed seat, and the first locking bolt slides in the sliding groove. After the limiting plate rotates by a certain angle, it is locked and fixed by the fixed seat and the first locking bolt.

[0014] The beneficial effect of adopting the above further scheme is:

[0015] The sliding groove provided on the limiting plate allows the first locking bolt on the fixed seat to slide inside it, thus realizing the angular adjustment of the limiting plate within a certain range. This design enables the workbench to quickly adjust the angle according to different processing requirements, improving the adaptability and flexibility of the workbench. The operator can easily realize the angular adjustment of the limiting plate by simply adjusting the position of the first locking bolt in the sliding groove. This adjustment method is simple and fast, without complex operation steps and tools, reducing the operation difficulty and time cost. After the limiting plate rotates to the required angle, through the close cooperation of the fixed seat and the first locking bolt, the limiting plate can be firmly locked in the fixed position. This locking method ensures that the limiting plate will not move or loosen accidentally during the processing, improving the stability and safety of the workbench.

[0016] Further, a second locking bolt is installed above the gear on the bracket, and after the support column is lifted or lowered, it is locked and fixed by the second locking bolt.

[0017] The beneficial effect of adopting the above further scheme is:

[0018] The design of the second locking bolt enables the support column to be firmly fixed on the bracket by the locking bolt after the support column is lifted or lowered to the required position. This locking method effectively prevents the support column from loosening or displacing due to vibration or external force during the processing, ensuring the stability and safety of the workbench.

[0019] Further, the fixture is provided with a suction cup, a fixed column is provided at the top of the suction cup, a bushing is sleeved on the fixed column, a clamping plate is provided on the bushing, a clamping block is attached to the surface of the clamping plate, and the clamping plate contacts the workpiece through the clamping block.

[0020] The beneficial effect of adopting the above further scheme is:

[0021] The bushing is sleeved on the fixed column, allowing the clamping plate to be adjusted in angle and position within a certain range. This design enables the fixture to adapt to workpieces of different shapes and sizes, improving the versatility and flexibility of the fixture. By adjusting the position and angle of the clamping plate and the clamping block, effective clamping of different workpiece surfaces can be achieved. This design allows the fixture to be widely used in various precision machining scenarios.

[0022] Furthermore, the bushing is provided with fixing holes, and screws are installed in the fixing holes. The bushing is locked and fixed to the fixed column through the screws.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The screw locking and fixing method can provide strong fastening force, ensuring a tight connection between the bushing and the fixed column. This fastening method effectively prevents the loosening or displacement of the bushing during operation, ensuring the stability of the mechanical structure. The screw locking and fixing method is relatively simple. During installation, only need to pass the screw through the fixing hole on the bushing and tighten it. This installation method does not require complex tools or equipment, reducing the installation difficulty and cost.

[0025] The utility model provides a multifunctional workbench for precision machining. It has the following beneficial effects:

[0026] The fixture equipped on the workbench surface adopts a suction cup and clamping plate design, which can firmly clamp workpieces of various shapes and sizes. The suction cup realizes the flexible installation and adjustment of the fixture through the combination of the fixed column and the bushing. The clamping block attached to the clamping plate ensures the stability and precision of the workpiece during machining.

[0027] The LED backlight board laid on one side of the tabletop provides sufficient and uniform lighting, facilitating the operator to view drawings, measuring tools, etc. during machining, improving work efficiency and accuracy.

[0028] Through the meshing transmission of the worm and the worm gear, the rotation of the main shaft is realized, and then the support column is driven to lift. This transmission method has the advantages of large transmission ratio, compact structure, good self-locking property, etc., ensuring the accuracy and stability of the workbench height adjustment.

[0029] The combined design of the support column and the cross beam not only enhances the load-bearing capacity of the workbench, but also makes the height and angle adjustment of the workbench more flexible. By adjusting the lifting of the support column and the fixed position of the cross beam, the height and angle requirements for different machining needs can be met.

[0040] Please refer to Figures 1 to 4 as shown, the embodiments provided by the present utility model are as follows:

[0041] Embodiment 1

[0042] A multi-functional workbench for precision machining, comprising a bottom plate 1, on which a table plate 2 is erected through a bracket 7. A workbench surface 4 is laid on the upper surface of the table plate 2. A fixture 6 is adsorbed on the workbench surface 4, and a workpiece 5 is clamped and fixed on the workbench surface 4 through the fixture 6. The fixture 6 is provided with a suction cup 21. A fixing column 23 is arranged at the top of the suction cup 21. A bushing 20 is sleeved on the fixing column 23. A fixing hole 22 is arranged on the bushing 20. A screw is installed in the fixing hole 22. The bushing 20 is locked and fixed on the fixing column 23 through the screw. The screw locking and fixing method can provide a strong fastening force to ensure the tight connection between the bushing 20 and the fixing column 23. This fastening method effectively prevents the loosening or displacement of the bushing 20 during the working process and ensures the stability of the mechanical structure. The screw locking and fixing method is relatively simple. During the installation process, only need to pass the screw through the fixing hole 22 on the bushing 20 and tighten it. This installation method does not require complex tools or equipment, reducing the installation difficulty and cost. A clamping plate 24 is arranged on the bushing 20. A clamping block 19 is attached to the surface of the clamping plate 24. The clamping plate 24 contacts the workpiece 5 through the clamping block 19. The bushing 20 is sleeved on the fixing column 23, allowing the clamping plate 24 to be adjusted in angle and position within a certain range. This design enables the fixture 6 to adapt to workpieces 5 of different shapes and sizes, improving the versatility and flexibility of the fixture 6. By adjusting the position and angle of the clamping plate 24 and the clamping block 19, effective clamping of the surfaces of different workpieces 5 can be achieved. This design enables the fixture 6 to be widely used in various precision machining scenarios. An LED backlight plate 3 is laid on one side of the table plate 2 where the workbench surface 4 is located, facilitating operations such as the user viewing drawings.

[0043] Embodiment Two

[0044] Such as Figures 1 to 4As shown in the figure, a multi-functional workbench for precision machining proposed by the present utility model, compared with Embodiment 1, this embodiment further includes: a main shaft 16 is rotatably installed on a bracket 7 through a bearing, a worm gear 17 is provided on the main shaft 16, a worm 10 is provided on the bracket 7 through a square pipe, a hand wheel 9 is provided at one end of the worm 10 away from the square pipe, and gears 8 are provided at both ends of the main shaft 16. The worm 10 and the worm gear 17 are meshed with each other. By driving the worm 10 to rotate through the hand wheel 9, the main shaft 16 is driven to rotate, so that the gears 8 at both ends of the main shaft 16 squeeze and push the support column 15 to lift. When the lead angle of the worm 10 is less than the equivalent friction angle between the meshing teeth, the worm gear 17 and worm 10 transmission mechanism has self-locking property. This means that without applying external force, the worm gear 17 cannot rotate by itself, thus ensuring the stability and safety of the workbench during the lifting process. A second locking bolt 18 is installed above the gear 8 on the bracket 7. After the support column 15 is lifted, it is locked and fixed by the second locking bolt 18. The design of the second locking bolt 18 enables the support column 15 to be firmly fixed on the bracket 7 through the locking bolt after the support column 15 is lifted to the required position. This locking method effectively prevents the support column 15 from loosening or displacing due to vibration or external force during the machining process, ensuring the stability and safety of the workbench.

[0045] Embodiment 3

[0046] As Figures 1 to 4 shown in the figure, a multi-functional workbench for precision machining proposed by the present utility model, compared with Embodiment 1, this embodiment further includes: a support column 15 is inserted into the bracket 7, the support column 15 is in contact with the gear 8, a cross beam 12 is provided at the top of the support column 15, fixing seats 11 are provided at both ends of the cross beam 12, the table board 2 is installed on the fixing seats 11 through a limiting plate 13, a chute is provided on the limiting plate 13, a first locking bolt 14 is installed on the fixing seat 11, and the first locking bolt 14 slides in the chute. After the limiting plate 13 rotates an angle, it is locked and fixed through the fixing seat 11 and the first locking bolt 14. The chute provided on the limiting plate 13 allows the first locking bolt 14 on the fixing seat 11 to slide inside it, thereby realizing the angle adjustment of the limiting plate 13 within a certain range. This design enables the workbench to quickly adjust the angle according to different machining requirements, improving the adaptability and flexibility of the workbench. The operator only needs to adjust the position of the first locking bolt 14 in the chute to easily realize the angle adjustment of the limiting plate 13. This adjustment method is simple and fast, without complicated operation steps and tools, reducing the operation difficulty and time cost. After the limiting plate 13 rotates to the required angle, through the close cooperation of the fixing seat 11 and the first locking bolt 14, the limiting plate 13 can be firmly locked in the fixed position. This locking method ensures that the limiting plate 13 will not move or loosen accidentally during the machining process, improving the stability and safety of the workbench.

[0047] Working principle:

[0048] The fixture 6 on the workbench surface 4 realizes the stable clamping of the workpiece 5 through the combination of the suction cup 21 and the clamping plate 24. The suction cup 21 utilizes the air pressure difference to generate suction force to fix the workpiece 5 on the workbench surface 4; the clamping plate 24 contacts the surface of the workpiece 5 through the clamping block 19 to further increase the clamping stability and accuracy. Moreover, the suction cup 21 of the fixture 6 realizes flexible installation and adjustment through the combination of the fixed column 23 and the bushing 20. The fixing hole 22 on the bushing 20 is used to install the screw, and by rotating the screw, the position of the bushing 20 on the fixed column 23 can be adjusted, so as to realize the fine adjustment of the angle and position of the fixture 6.

[0049] When the operator rotates the handwheel 9, the worm 10 rotates accordingly. Due to the meshing relationship between the worm 10 and the worm wheel 17, the rotation of the worm 10 drives the worm wheel 17 to rotate. The worm wheel 17 is fixed on the main shaft 16, so the main shaft 16 also rotates accordingly. The rotation of the main shaft 16 drives the pillar 15 to move up and down through the gears 8 at both ends of the main shaft 16 by friction. This transmission method converts the rotational motion of the main shaft 16 into the linear motion of the pillar 15, thereby realizing the adjustment of the workbench height. When the table board 2 is adjusted to the required height, the table board 2 is further locked by tightening the second locking bolt 18 to further ensure the stability and accuracy of the workbench.

[0050] The chute opened on the limit plate 13 allows the first locking bolt 14 on the fixed seat 11 to slide inside it, thus realizing the angle adjustment of the limit plate 13 within a certain range. The operator only needs to adjust the position of the first locking bolt 14 in the chute to easily realize the angle adjustment of the limit plate 13. This adjustment method is simple and fast, without complex operation steps and tools, reducing the operation difficulty and time cost. After the limit plate 13 rotates to the required angle, through the close cooperation of the fixed seat 11 and the first locking bolt 14, the limit plate 13 can be firmly locked in the fixed position.
