Description

Technical Field

[0001] This utility model relates to the field of workbench technology, and in particular to a multifunctional workbench for instrument and meter repair. Background Technology

[0002] In the field of precision instrument repair, the workbench is the core operating platform, and its design rationality directly affects repair efficiency, operating comfort and inspection accuracy. As instruments and meters develop towards integration, miniaturization and precision, the repair scenarios have put forward higher requirements for the functionality and adaptability of the workbench. However, traditional instrument repair workbench generally have the problems of fixed structure and single function, which makes it difficult to meet the needs of modern repair operations.

[0003] Traditional workbenches typically have a fixed table height, making it impossible to adjust to the operator's height or posture. During extended periods of operation, maintenance personnel are often forced to hunch over due to the excessive height of the table, reducing operational comfort and impacting concentration and efficiency due to fatigue. Furthermore, traditional workbenches lack flexible adjustment capabilities, often concealing instrument malfunctions in hidden locations such as the back or bottom. This necessitates frequent movement, instrument rotation, or repositioning to change the inspection perspective, increasing operational redundancy. Additionally, traditional workbenches suffer from significant deficiencies in tool storage and retrieval. Most workbenches are equipped with only fixed drawers or open tool racks, resulting in a haphazard storage of tools. Operators must stand up to search for or bend over to retrieve tools, wasting considerable time outside of maintenance tasks. Utility Model Content

A maintenance table is provided on the upper surface of the workbench. A rotating shaft is fixed at the bottom of the maintenance table and is rotatably connected to the surface of the workbench. A tool support frame is provided above the maintenance table. A support groove is opened on the surface of the tool support frame, and maintenance tools are loaded in the support groove.

[0006] Preferably, the adjustment assembly further includes a lifting rack fixed to the inner side of the lifting sleeve plate with a drive cavity surface. The lifting rack is meshed with a lifting gear, and a drive shaft is fixed at the center of the lifting gear. The drive shaft is rotatably connected between two sets of storage sleeves. A worm gear is fixed to one end of the drive shaft, and a worm is meshed to the surface of the worm gear. The worm is rotatably connected to the surface of one set of storage sleeves via a bracket. A handwheel is fixed to one end of the worm.

[0007] Preferably, a driven gear is fixed at the bottom end of the rotating shaft, a rotary motor is fixed on the lower surface of the worktable near the driven gear, a drive main gear is fixed at the output end of the rotary motor, and the drive main gear meshes with the driven gear. A drive cavity adapted to the driven gear and the drive main gear is opened inside the worktable. Several sets of positioning pulleys arranged in a ring array are fixed on the surface of the worktable, and the surfaces of the positioning pulleys are slidably connected in the positioning wheel grooves opened on the lower surface of the worktable.

[0008] Preferably, the inner surface of the shield is fixed with a pull-out slide rail, and both sides of the tool carrier are fixed with pull-out pulleys. The tool carrier is slidably connected to the inside of the pull-out slide rail via the pull-out pulleys.

[0009] Preferably, it also includes a movable component installed at the bottom of the storage sleeve. The movable component includes a base fixed to the lower surface of the storage sleeve. Support legs are fixed to the front and rear sides of the lower surface of the two sets of bases. A movable wheel is provided inside the base near the support legs.

[0010] Preferably, a hinge frame is provided between the movable wheel and the base. The hinge frame consists of two sets of hinge rods that are hinged to each other. Guide rails are fixed on opposite sides of the base and the movable wheel. One end of each set of hinge rods is slidably connected to the surface of the two sets of guide rails, and the other end of each set of hinge rods is hinged to the surface of the movable wheel and the base through a hinge seat. A threaded frame is fixed at the end of one set of hinge rods. A bidirectional lead screw is rotatably connected inside the base, and the bidirectional lead screw is threadedly connected to the threaded frame.

[0011] Preferably, a rotating shaft is rotatably connected to the center of the surface of the base, and a bevel gear pair is installed between the bidirectional lead screw and the rotating shaft. The bevel gear pair consists of two meshing bevel gears, one of which is fixed to the surface of the bidirectional lead screw, and the other is fixed to one end of the rotating shaft.

[0013] The beneficial effects of this utility model are: 1. The adjustable components adapt to different user needs, optimizing the work experience. The workbench height can be precisely adjusted according to the operator's height and posture habits, avoiding hunching caused by an excessively high table or fatigue caused by an excessively low table. This physiologically reduces the labor intensity of long-term maintenance work, improving operational comfort. The adjustable inspection angle ensures maintenance accuracy. The maintenance table can rotate smoothly at all angles. For precision instruments with multiple interfaces and lines, operators can quickly switch inspection perspectives without frequently moving their bodies or instruments. This is especially convenient for observing fault points in hidden parts such as the back and bottom of instruments, significantly improving the accuracy and comprehensiveness of maintenance. The pull-out tool holder allows for flexible pushing and pulling through the combination of pulleys and rails. Combined with the partitioned storage slots, different types of tools such as screwdrivers, multimeters, and soldering pens can be stored separately. Operators can quickly access tools without getting up or searching around, adapting to maintenance scenarios with frequent tool switching. Meanwhile, the cushioning sponge pads effectively prevent tool collisions and wear, extending tool life.

[0014] 2. Seamless switching between moving and stationary modes is achieved through the set-up mobile components. The mechanical linkage structure driven by the handwheel allows for the raising and lowering of the moving wheels with a single operation, quickly switching between mobile and stationary modes. When cross-workstation maintenance, equipment inspection, or site tidying is required, lowering the moving wheels allows the workbench to be moved flexibly. After reaching the target position, retracting the moving wheels allows the support legs to touch the ground, immediately switching to a stable working state. The switching between moving and stationary modes can be completed without the need for multiple people to cooperate, saving labor costs and improving work efficiency. No additional auxiliary tools are required, making it suitable for various scenarios such as fixed workstation maintenance and mobile emergency repairs. After the support legs touch the ground, they form a rigid support with the ground, preventing the workbench from accidentally sliding during maintenance. Attached Figure Description

[0021] It also includes a movable component 4 installed at the bottom of the storage sleeve 302. The movable component 4 includes a base 401 fixed to the lower surface of the storage sleeve 302. Support legs 402 are fixed on both the front and rear sides of the lower surface of the two sets of bases 401. A movable wheel 403 is provided inside the base 401 near the support legs 402.

[0022] A hinge frame 404 is provided between the movable wheel 403 and the base 401. The hinge frame 404 consists of two sets of hinge rods that are hinged to each other. Guide rails 405 are fixed on opposite sides of the base 401 and the movable wheel 403. One end of each set of hinge rods is slidably connected to the surface of the two sets of guide rails 405, and the other end of each set of hinge rods is hinged to the surface of the movable wheel 403 and the base 401 through hinge seats.

[0023] A rotating shaft 408 is rotatably connected to the center of the surface of the base 401. A bevel gear pair 410 is installed between the bidirectional lead screw 407 and the rotating shaft 408. The bevel gear pair 410 consists of two meshing bevel gears. One bevel gear is fixed to the surface of the bidirectional lead screw 407, and the other bevel gear is fixed to one end of the rotating shaft 408. The other end of the rotating shaft 408 extends to the outside of the base 401 and is fixed with a handwheel 409.

[0024] A light is fixed to the side of the shield 2 facing the maintenance table 309. An anti-static rubber pad is attached to the upper surface of the maintenance table 309. A cushioning sponge pad is fixed to the inner wall of the bearing groove of the tool support frame 315.

[0025] It should be noted that the lighting on the side of the shield 2 facing the maintenance table 309 can provide sufficient light during maintenance work, improve the clarity of inspection in the dark, and provide anti-static protection. The anti-static rubber pad on the upper surface of the maintenance table 309 can effectively release static electricity and prevent static electricity from damaging the circuit components of precision instruments.

[0026] The working principle and usage process of this utility model are as follows: During use, the adjustment component 3 can achieve multi-dimensional adjustment of the height of the workbench 1, the angle of the repair table 309, and the tool position to meet the needs of different repair scenarios. When the height of the workbench 1 needs to be adjusted, manually turn the handwheel 308 to drive the worm gear 307 fixed thereto to rotate synchronously. The worm gear 307 drives the worm wheel 306 to rotate through meshing, thereby causing the drive shaft 305 at the center of the worm wheel 306 to rotate accordingly. The lifting gears 304 at both ends of the drive shaft 305 are connected to the drive shaft... 305 rotates coaxially, and the lifting gear 304 meshes with the lifting rack 303 on the inner side of the lifting sleeve 301, converting the rotational motion of the gear into the linear motion of the lifting sleeve 301. Since the lifting sleeve 301 is slidably fitted inside the receiving sleeve 302, the lifting sleeve 301 slides up and down along the inner wall of the receiving sleeve 302, ultimately driving the top worktable 1 to achieve height adjustment, adapting to the working height requirements of different operators. When it is necessary to rotate and adjust the maintenance table 309, the rotary motor 313 is started, and its output end... The main drive gear 312 rotates, and the rotation of the main drive gear 312 and the bottom end of the rotating shaft 310 is transmitted through the meshing of gear 311, causing the rotating shaft 310 to rotate. The top end of the rotating shaft 310 is fixedly connected to the maintenance table 309, thereby driving the maintenance table 309 to rotate around the center of the rotating shaft 310. At the same time, the positioning pulley 314 on the surface of the worktable 1 slides along the positioning wheel groove on the lower surface of the maintenance table 309, providing support and guidance for the maintenance table 309, ensuring smooth rotation, and facilitating the operator to inspect instruments from different angles. When the tool carrier 315 needs to be pulled out to retrieve maintenance tools, the tool carrier 315 is slidably connected to the pull-out slide rail 318 on the inner side of the shield 2 via pull-out pulleys 317 on both sides. The operator can pull the tool carrier 315 with the handle 316 to make it slide back and forth along the pull-out slide rail 318, so as to realize convenient retrieval and storage of tools. The bearing groove on the surface of the tool carrier 315 is used to place maintenance tools. The cushioning sponge pad in the groove can reduce the collision and wear of tools during storage and retrieval, and play a role in protecting the tools.

[0027] Furthermore, the movable component 4 enables the flexible transfer and stable parking of the worktable. By rotating the handwheel 409, the rotating shaft 408 extending to the outside of the base 401 is rotated. The rotating shaft 408 transmits power to the bidirectional lead screw 407 through the bevel gear pair 410, causing the bidirectional lead screw 407 to rotate inside the base 401. The bidirectional lead screw 407 is threadedly connected to the threaded frame 406 on the hinge frame 404. The rotational motion of the bidirectional lead screw 407 is converted into the linear movement of the threaded frame 406, driving the two sets of hinge rods of the hinge frame 404 to change angle. The two ends of the hinge rods slide along the guide rails 405 on the base 401 and the movable wheel 403 respectively and rotate around the hinge seat, realizing the lifting and lowering of the movable wheel 403. When the movable wheel 403 descends and contacts the ground, it supports the support leg 402. At this time, the worktable can be pushed to move through the movable wheel 403. When the movable wheel 403 rises and retracts into the base 401, the support leg 402 lands, realizing the stable fixation of the worktable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
