Description

Technical Field

[0001] This utility model belongs to the field of coupling technology, and specifically relates to a coupling half-body alignment and clamping worktable. Background Technology

[0002] Couplings are mainly used to connect two shafts in different mechanisms, enabling them to rotate together to transmit torque. A coupling generally consists of two half-couplings, each half-coupling being connected to the driving shaft and the driven shaft respectively through its shaft end.

[0003] Currently, Chinese utility model patent CN210650587U discloses a clamping worktable. In existing coupling manufacturing processes, two half-couplings generally need to be aligned and clamped before bolting and fixing them into a complete coupling. However, due to differences in coupling models, the shaft end diameters of different couplings are also inconsistent. Existing clamping worktables cannot clamp and fix multiple models of couplings simultaneously, thus affecting the efficiency of coupling assembly. Furthermore, the half-couplings cannot rotate after clamping. If the alignment of the couplings before clamping is inaccurate, resulting in deviations or misalignments, the half-couplings need to be disassembled and re-clamped, which is inconvenient for accurate alignment and subsequent bolting and assembly, resulting in low practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a coupling half-body alignment and clamping worktable, which has the advantages of being able to clamp and fix various types of couplings and to allow for rotational adjustment after the half-body coupling is clamped and fixed.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a coupling half-body alignment and clamping worktable, including a worktable, a positive and negative threaded screw is rotatably connected inside the worktable, a sliding table is threadedly sleeved on both sides of the surface of the positive and negative threaded screw, a fixed rod is bolted to the top of the two sliding tables and slidably connected to the worktable, a rotating seat is rotatably connected to the side of the two fixed rods that are close to each other, and a stepped locking groove is opened inside the rotating seat.

[0006] The above technical solution utilizes stepped locking grooves inside the rotating seats to secure coupling halves of various diameters. Then, the two rotating seats are brought closer together, clamping and aligning the coupling halves. This facilitates rapid assembly and improves installation efficiency. By clamping and aligning the two coupling halves together, rotating the rotating rod causes the coupling halves to rotate between the two rotating seats. This allows the clamped coupling halves to rotate at an angle, facilitating accurate bolting and assembly and improving practicality.

[0007] The present invention is further configured such that: a rotating rod is provided at the top of the positive and negative threaded screw and is rotatably connected to the worktable; two fixed rods are respectively sleeved at both ends of the rotating rod surface; a sliding cylinder is rotatably connected inside the fixed rod and is slidably sleeved with the rotating rod; strip-shaped grooves are provided on both sides of the rotating rod surface and are engaged with the sliding cylinders; a connecting shaft is rotatably connected inside the fixed rod and bolted to the rotating seat; synchronous pulleys are fixedly sleeved on the surfaces of the connecting shaft and the sliding cylinders; and synchronous belts are drivenly sleeved on the surfaces of the two synchronous pulleys.

[0008] By adopting the above technical solution, the clamped and fixed coupling half can be rotated at an angle, making it convenient and accurate to bolt and assemble it.

[0009] The present invention is further configured such that: both sides inside the worktable are rotatably connected to ball bearings that are slidably connected to the sliding table.

[0010] The above technical solution supports the sliding of the sliding table and reduces the friction when the sliding table slides inside the worktable.

[0011] The present invention is further configured such that an anti-slip pad is adhered to the inner surface of the locking groove.

[0012] By adopting the above technical solution, the friction of the inner surface of the clamping groove is increased, thereby improving the clamping stability.

[0013] The present invention is further configured such that threaded holes are provided on both sides of the bottom of the workbench.

[0014] By adopting the above technical solution, the worktable can be easily bolted and fixed by using bolts to penetrate the threaded hole and engage with the thread of the worktable.

[0015] The present invention is further configured such that: the ends of the rotating rod and the positive and negative threaded screws that are far apart from each other are each bolted with a handwheel that is rotatably connected to the worktable.

[0016] The above technical solution allows for easy adjustment by turning the handwheel to rotate the positive and negative thread screws and the rotating rod respectively.

[0017] The present invention is further configured such that an inspection door is opened and bolted to the other side of the workbench.

[0018] By adopting the above technical solution, the interior of the workbench can be opened, thereby facilitating the repair or replacement of damaged parts.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By utilizing the stepped locking grooves inside the rotating base, coupling halves of various diameters can be secured. Then, the two rotating bases are moved closer together, thus clamping and aligning the coupling halves. This facilitates quick assembly of the couplings, improving installation efficiency.

[0021] 2. By clamping and aligning the two coupling halves together, rotating the rotating rod causes the coupling halves to rotate between the two rotating seats. This allows the clamped coupling halves to rotate at an angle, facilitating accurate bolting and assembly and improving practicality. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 The coupling half-body alignment and clamping worktable includes a worktable 1. A threaded rod 2 with both positive and negative threads is rotatably connected inside the worktable 1. Sliding platforms 3 are threaded onto both sides of the surface of the threaded rod 2. Fixed rods 4, which are slidably connected to the top of each sliding platform 3, are bolted to the top of each sliding platform 3. Rotating seats 5 are rotatably connected to the sides of the two fixed rods 4 that are close to each other. Each rotating seat 5 has a stepped locking groove 6 inside. By utilizing the stepped locking groove 6 inside the rotating seat 5, coupling half-body parts of various diameters are clamped and secured. Then, the two rotating seats 5 are moved closer together, thereby clamping and aligning the coupling half-body parts. This facilitates quick assembly of the coupling and improves installation efficiency.

[0030] refer to Figure 2Both sides of the worktable 1 are rotatably connected to ball bearings 15 that are slidably connected to the sliding table 3. These ball bearings support the sliding of the sliding table 3 and reduce the friction when the sliding table 3 slides inside the worktable 1.

[0031] refer to Figure 2 An anti-slip pad 14 is bonded to the inner surface of the locking groove 6. This increases the friction on the inner surface of the locking groove 6 and improves clamping stability.

[0032] refer to Figure 1 , Figure 2 The worktable 1 has threaded holes 16 on both sides of its bottom. By using bolts to pass through the threaded holes 16 and engage with the threads of the worktable 1, the worktable 1 can be easily bolted and fixed.

[0033] Brief description of the usage process: By inserting the shaft ends of the two coupling halves into the locking grooves 6, the rotating seat 5 can secure coupling halves of various diameters through the stepped locking grooves 6. Then, by rotating the positive and negative threaded screws 2, they engage with the threads of the two sliding tables 3 respectively. Since the threads on both sides of the positive and negative threaded screws 2 are in opposite directions, they can drive the fixing rods 4 on the top of the sliding tables 3 to slide in opposite directions. This brings the two fixing rods 4 closer together, clamping and aligning the coupling halves secured inside the two rotating seats 5 for bolting assembly and fixation.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The coupling halves are aligned and clamped together on a worktable. A rotating rod 7, rotatably connected to the worktable 1, is located at the top of the positive and negative threaded screws 2. Two fixed rods 4 are respectively sleeved at both ends of the rotating rod 7. A sliding cylinder 9, rotatably connected to the rotating rod 7, is rotatably connected inside the fixed rod 4. Both sides of the rotating rod 7 have strip-shaped grooves 8 that engage with the sliding cylinder 9. A connecting shaft 12, bolted to a rotating seat 5, is rotatably connected inside the fixed rod 4. Synchronous pulleys 10 are fixedly sleeved on the surfaces of both the connecting shaft 12 and the sliding cylinder 9. Synchronous belts 11 are driven to the surfaces of the two synchronous pulleys 10. By clamping and aligning the two coupling halves together, rotating the rotating rod 7 causes the coupling halves to rotate between the two rotating seats 5. This allows the clamped coupling halves to rotate at an angle, facilitating accurate bolting and assembly and improving practicality.

[0036] refer to Figure 1 , Figure 2 Both the rotating rod 7 and the screw rod 2, at their opposite ends, are bolted with handwheels 13 that are rotatably connected to the worktable 1. This allows for easy adjustment by turning the handwheels 13 to rotate the screw rod 2 and the rotating rod 7 respectively.

[0037] refer to Figure 1 An inspection door 17 is opened and bolted to the other side of the workbench 1. The interior of the workbench 1 can be opened to facilitate the maintenance or replacement of damaged parts.

[0038] Brief description of the usage process: The two coupling halves are clamped together for alignment. Then, by rotating the rotating rod 7, it engages with the sliding cylinder 9 via the strip groove 8, thereby driving the sliding cylinder 9 to rotate. When the sliding table 3 slides inside the worktable 1, it can drive the sliding cylinder 9 to slide synchronously, and the strip groove 8 allows the rotating rod 7 to drive the sliding cylinder 9 to rotate. Afterwards, the sliding cylinder 9 is driven by the synchronous pulley 10 and the synchronous belt 11, which in turn drives the connecting shaft 12 to rotate, allowing the two couplings clamped and aligned between the two rotating seats 5 to rotate, facilitating accurate bolting and assembly.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
