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

[0002] Mechanical parts are the basic components of machinery and are inseparable individual parts that make up machinery and machines. Most of them are metal structures. In order to make the parts convenient for subsequent use, they need to be machined. During the processing of mechanical parts, they are generally carried out on a specific workbench to facilitate the processing of mechanical parts by workers.

[0003] Publication number: CN221538866U, discloses: a workbench for machining mechanical parts that is easy to adjust in height, wherein the output end of the motor drives the rotating shaft to rotate, and the rotation of the rotating shaft can drive the first gear to rotate. Since the first gear is meshed with the four second gears, the four second gears can be rotated by the rotation of the first gear, and then the four threaded sleeves are driven to rotate. The rotation of the threaded sleeves can cause the work plate to start moving. When the work plate moves to the specified position, the motor is turned off, and the work plate will stay at the current position, which is convenient for workers of different heights to use the work plate. The workers can adjust the height of the work plate according to their height.

[0004] The above-mentioned prior art still has the following shortcomings in the specific implementation process:

[0005] Only the height of the work plate can be adjusted, and the angle of the work plate cannot be adjusted. When multi-directional processing of mechanical parts is performed, the staff is required to rotate around the work plate or rotate the mechanical parts placed on the work plate. When the parts are heavy, it is more laborious, which increases the labor intensity of the staff and affects the processing efficiency of the parts. At the same time, when adjusting the height of the work plate, multiple gears are required to cooperate with each other, which increases the manufacturing cost of the device.

[0006] In response to the above problems, we propose a workbench for machining mechanical parts. Utility Model Content

DETAILED DESCRIPTION

[0024] This specific embodiment is a workbench for machining mechanical parts, such as Figures 1-6 As shown, the workbench for machining mechanical parts includes a support plate 1 and a machining table 2. A through hole is provided on the support plate 1, and a movable sleeve 3 is rotatably provided inside the through hole. A cylindrical gear 4 is movably provided inside the movable sleeve 3. The upper end of the cylindrical gear 4 is connected to the bottom of the machining table 2, and the lower end of the cylindrical gear 4 is rotatably connected to a lifting plate 5. A base 6 is provided on the lower side of the lifting plate 5, and a slide groove 7 is provided on the base 6. A first screw rod 8 is provided in the slide groove 7, and two sliders 9 are threaded on the first screw rod 8. A support arm 10 is hinged between the top of the slider 9 and the lifting plate 5. An angle adjustment component is provided on the lower side of the support plate 1 to cooperate with the cylindrical gear 4.

[0025] The processing table 2 facilitates the placement of mechanical parts to be processed, wherein the threaded cooperation of the first screw 8 and the slider 9 facilitates the flexible adjustment of the mutual distance between the two sliders 9, combined with the hinged effect of the two ends of the support arm 10, and then the lifting plate 5 is pushed upward. Under the active cooperation of the cylindrical gear 4 and the movable sleeve 3, the cylindrical gear 4 and the processing table 2 are driven to move upward synchronously, so as to achieve the purpose of adjusting the height of the mechanical parts during the processing process, and facilitate workers of different heights to process the mechanical parts. There is no need to set multiple gears, which effectively saves the manufacturing cost of the device. At the same time, under the action of the angle adjustment component, combined with the rotation cooperation of the cylindrical gear 4 and the lifting plate 5, it is convenient to adjust the cylindrical gear 4 to rotate, thereby driving the processing table 2 to rotate synchronously, achieving the purpose of adjusting the angle of the mechanical parts during the processing, and facilitating the workers to perform multi-directional processing operations on the mechanical parts. This solves the problem that the existing technology can only adjust the height of the work plate but cannot adjust the angle of the work plate. When multi-directional processing of mechanical parts is performed, the workers are required to rotate around the work plate or rotate the mechanical parts placed on the work plate, which increases the labor intensity of the workers and affects the processing efficiency of the parts.

[0026] The angle adjustment assembly includes a second screw rod 11, a movable block 12, a rack 13, a support rod 17 and a second motor 18. The second screw rod 11 is arranged on the lower side of the support plate 1, and the movable block 12 is threaded on the second screw rod 11. The rack 13 is fixed to the front end of the movable block 12, and the rack 13 is engaged with the cylindrical gear 4. Two fixed blocks 16 are relatively fixed at the bottom of the support plate 1. The second screw rod 11 is rotatably set between the two fixed blocks 16. The support rod 17 is arranged on the front side of the second screw rod 11, and the two ends of the support rod 17 are fixedly connected to the fixed blocks 16 on both sides. The support rod 17 passes through the movable block 12, and the movable block 12 and the support rod 17 are movably matched.

[0027] Through the threaded cooperation between the second screw rod 11 and the movable block 12, it is convenient to flexibly adjust the movable block 12 to move horizontally along the direction of the support rod 17, thereby driving the synchronous movement of the rack 13. Under the meshing action of the rack 13 and the cylindrical gear 4, the cylindrical gear 4 is driven to rotate, thereby achieving the purpose of adjusting the placement angle of the processing table 2 and the mechanical parts placed on the processing table 2, making it convenient for the staff to perform multi-directional processing operations on the mechanical parts. Among them, the support rod 17 plays a role of supporting and limiting the movable block 12, ensuring the stability of the movable block 12 during movement, thereby ensuring the stability of the rack 13 during movement.

[0028] The second motor 18 is mounted on the left fixed block 16 , and the output end of the second motor 18 is connected to the left end of the second screw rod 11 .

[0029] A first motor 14 is installed on the right side of the base 6. The output end of the first motor 14 is connected to the right end of the first screw rod 8. Limiting grooves are provided on the front and rear sides of the inner wall of the slide 7. Limiting blocks are fixed on the front and rear sides of the slider 9. The limiting blocks and the limiting grooves are movably coordinated to effectively limit and guide the slider 9, thereby ensuring the stability of the two sliders 9 during the sliding process. The thread directions of the center threaded holes of the two sliders 9 are opposite.

[0030] Two guide rods 15 are relatively fixed at the bottom of the support plate 1. The guide rods 15 pass through the lifting plate 5, and the lifting plate 5 and the guide rods 15 are movably coordinated to effectively limit and guide the lifting plate 5, thereby ensuring the stability of the lifting plate 5 during the up and down movement process. Several support legs 19 are fixed at the bottom of the support plate 1, and the base 6 is fixedly connected to the support legs 19.

[0031] Example:

[0032] When in use, first place the mechanical parts to be processed on the processing table 2 for processing;

[0033] When the height of a mechanical part needs to be adjusted during machining, the first motor 14 is started, and the first screw rod 8 is driven to rotate by the first motor 14. Under the threaded cooperation between the slider 9 and the first screw rod 8, combined with the active cooperation between the limit block and the limit groove, the two sliders 9 are driven to stably move away from each other. In conjunction with the hinged action at both ends of the support arm 10 and the active cooperation between the lifting plate 5 and the guide rod 15, the lifting plate 5 is stably lifted upward.

[0034] The cylindrical gear 4 and the movable sleeve 3 cooperate with each other to drive the cylindrical gear 4 and the processing table 2 to move upward synchronously, thereby achieving the purpose of adjusting the height of the mechanical parts during the processing, making it convenient for workers of different heights to process the mechanical parts, eliminating the need to set up multiple gears, and effectively saving the manufacturing cost of the device;

[0035] The rack 13 and the cylindrical gear 4 mesh with each other, so that the rack 13 has a limiting effect on the cylindrical gear 4 in the horizontal direction. When the rack 13 is stationary, the cylindrical gear 4 cannot rotate. However, the rack 13 has no limiting effect on the cylindrical gear 4 in the vertical direction, so that the cylindrical gear 4 can move longitudinally along the direction of the tooth groove on the rack 13 to achieve the effect of height adjustment.

[0036] During the processing of mechanical parts, when multi-directional processing operations are required on the mechanical parts, the second motor 18 is started, and the second screw rod 11 is driven to rotate by the second motor 18. Under the threaded cooperation between the movable block 12 and the second screw rod 11, and the sliding cooperation between the movable block 12 and the support rod 17, the movable block 12 is driven to move horizontally along the direction of the support rod 17. Through the horizontal movement of the movable block 12, the rack 13 is driven to move synchronously;

[0037] Among them, under the meshing action of the rack 13 and the cylindrical gear 4, combined with the rotational cooperation of the cylindrical gear 4 and the lifting plate 5, and the rotational cooperation of the movable sleeve 3 and the through hole on the support plate 1, the cylindrical gear 4 is driven to rotate. Through the rotation of the cylindrical gear 4, the processing table 2 and the mechanical parts placed on the processing table 2 are driven to rotate synchronously, so as to achieve the purpose of adjusting the angle of the mechanical parts, and facilitate the staff to perform multi-directional processing operations on the mechanical parts, and solve the problem that the existing technology can only adjust the height of the work plate but cannot adjust the angle of the work plate. When performing multi-directional processing on mechanical parts, the staff is also required to rotate around the work plate or rotate the mechanical parts placed on the work plate. When the weight of the parts is large, it is more laborious, which increases the labor intensity of the staff and affects the processing efficiency of the parts.

[0038] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the first motor 14 and the second motor 18 in the present invention are purchased on the market, and those skilled in the art can install, connect the wires and use them according to the requirements.
