Description

Technical Field

[0001] This utility model belongs to the field of cooler processing technology, and in particular relates to a cooler cylinder processing equipment. Background Technology

[0002] A cooler is a type of heat exchanger used to cool fluids. It typically uses water or air as the coolant to remove heat. They can be mainly classified into shell-and-tube coolers, plate coolers, and air-cooled coolers. Coolers are widely used heat exchange devices in industries such as metallurgy, chemical engineering, energy, transportation, light industry, and food processing; they are suitable for various operating conditions including cooling, condensation, heating, evaporation, and waste heat recovery. Therefore, among the many types of heat exchangers, coolers, especially shell-and-tube heat exchangers, remain of paramount importance.

[0003] Patent CN201920856710.2 discloses an automatic circumferential welding device for a cooler cylinder, comprising a housing with a circular hole on the right side wall of the housing, the circular hole connecting to the interior of the housing, a motor fixedly installed inside the housing, and the drive shaft of the motor extending through the circular hole to the outside of the housing. A circular block is fixedly installed at one end of the drive shaft extending to the outside of the housing. A circular groove is formed on the right side wall of the circular block, the circular groove being a circular recess. Threaded holes are respectively formed on the upper and lower outer walls of the circular block, the two threaded holes corresponding to each other and connecting to the circular groove. A screw is installed in the threaded hole, the thread extending through the threaded hole to the interior of the circular groove. This utility model uses two cylindrical rollers, whose cylindrical outer walls easily fit against the outer wall of the cooler cylinder, making it less likely to cause dents on the outer wall of the cooler cylinder.

[0004] In the aforementioned patent, the cylinder is clamped by rotating two screws to move the clips and blocks. However, in actual operation, it is difficult to make the two clips and blocks move synchronously, which causes the axis of the cylinder to not coincide with the axis of the circular groove, affecting subsequent processing.

[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 1-5 As shown, a cooler cylinder processing device includes a clamping cylinder 1, a drive mechanism, an auxiliary support mechanism, and a clamping mechanism. The clamping cylinder 1 is for inserting the end of the cooler cylinder. The drive mechanism is used to drive the clamping cylinder 1 to rotate. The auxiliary support mechanism is used to support the other end of the cooler cylinder. The clamping mechanism is used to fix the end of the cooler cylinder inside the clamping cylinder 1.

[0037] Specifically, the drive mechanism includes a drive shaft 21, a support base 22, and a drive component 23. The drive shaft 21 is rotatably connected to the support base 22, and one end of it is fixed to the end of the clamping cylinder 1. The drive component 23 is a conventional motor used to drive the drive shaft 21 to rotate.

[0038] Specifically, the auxiliary support mechanism includes a support plate 31, a connecting plate 32, and a roller 33. The connecting plate 32 is symmetrically arranged on the support plate 31; the two ends of the roller 33 are rotatably connected to the connecting plate 32.

[0039] Specifically, the clamping mechanism includes clamping rods 41, clamping plates 42, mounting plates 43, limiting sleeves 44, driving sleeves 45, limiting plates 46, a first elastic element 47, ball bearings 48, a push block 49, and a driving assembly. Preferably, there are four clamping rods 41, evenly distributed on the outer wall of the clamping cylinder 1, passing through the outer wall and sliding relative to the clamping cylinder 1. The clamping plate 42 is arc-shaped and connected to the end of the clamping rods 41. The mounting plate 43 is fixed to the outer wall of the clamping cylinder 1. The limiting sleeve 44 is fixed to the mounting plate 43, with its axis coinciding with the axis of the clamping cylinder 1. The driving sleeve 45 is rotatably connected to the limiting plate 46. The clamping sleeve 44 is located on the inner wall of the clamping sleeve 44; the limiting plate 46 is fixed on the clamping rod 41; the first elastic element 47 is a spring, which is sleeved on the clamping rod 41, with one end fixed on the limiting plate 46 and the other end fixed on the outer wall of the clamping cylinder 1; the ball bearing 48 is rotatably connected to the end of the clamping rod 41; the push block 49 is evenly fixed on the inner wall of the drive sleeve 45, and the push block 49 is correspondingly arranged with the clamping rod 41, and the push block 49 has an arc-shaped curved surface, with the ball bearing 48 in contact with the arc-shaped curved surface; when it is necessary to clamp the cooler cylinder, the end of the cylinder is inserted into the clamping cylinder 1, and the drive sleeve 45 is rotated by the drive assembly. The push block 49 on the inner wall of the drive sleeve 45 rotates with it, and the arc-shaped curved surface of the push block 49 presses the ball bearing 48 at the end of the clamping rod 41, so that the clamping rod 41 overcomes the elastic force of the first elastic element 47 and slides outward, driving the clamping plate 42 to move to the surface of the cylinder. The limiting plate 46 and the limiting sleeve 44 ensure the direction of movement of the clamping rod 41, and the first elastic element 47 provides the restoring force. Finally, multiple clamping plates 42 synchronously fit against the cylinder to achieve stable clamping; through the cooperation of the push block 49 and the ball 48, multiple clamping plates 42 can move synchronously to ensure that the axis of the cylinder coincides with the axis of the clamping cylinder 1, avoiding machining deviations caused by asynchronous clamping and improving machining accuracy; the contact design of the arc-shaped curved surface with the ball 48 can reduce frictional resistance, making the clamping process smoother and reducing component wear.

[0040] As a preferred embodiment, the drive assembly includes a tooth 451, a rotating shaft 452, a gear 453, a handle 454, and a locking component. The tooth 451 is evenly fixed on the outer wall of the drive sleeve 45; the rotating shaft 452 is rotatably connected to the mounting plate 43; the gear 453 is fixed on the rotating shaft 452 and meshes with the tooth 451; the handle 454 is fixed on the rotating shaft 452. Rotating the gear 453 via the handle 454 drives the drive sleeve 45 to rotate. After clamping, locking the gear 453 via the locking component locks the drive sleeve. Cylinder 45; The locking component includes a ratchet 456, a rotating shaft 457, a ratchet tooth 458, and a torsion spring 459. The ratchet 456 is fixed on the rotating shaft 452. One end of the rotating shaft is fixed on the mounting plate 43. The ratchet tooth 458 is rotatably connected to the rotating shaft and can be engaged with the ratchet tooth 458. The torsion spring is sleeved on the rotating shaft, and one torsion arm of the torsion spring is fixed on the rotating shaft, while the other torsion arm is fixed on the ratchet tooth 458. The ratchet is fixed on the rotating shaft 452, and the ratchet tooth 458 is mounted on the mounting plate 43 through the rotating shaft. The torsion spring ensures that the ratchet tooth 458 is always engaged with the ratchet. When the shaft 452 rotates clockwise, the ratchet 458 slides on the surface of the ratchet tooth 451. When the rotation stops, the ratchet 458 will engage in the groove of the ratchet, preventing the shaft 452 from rotating counterclockwise, thereby locking the drive sleeve 45. The ratchet and ratchet tooth 458 locking structure is simple and reliable, and can automatically lock after clamping, preventing the drive sleeve 45 from loosening due to external force and ensuring the continuity of clamping force. The torsion spring makes the locking process unnecessary, improving the convenience and stability of the equipment.

[0041] In other embodiments, a rubber plate 51 is fixed on the clamping plate 42. The rubber plate 51 on the clamping plate 42 is elastic. When the clamping plate 42 is in contact with the cylinder, the rubber plate 51 can increase the contact area with the cylinder surface through deformation, and at the same time, the friction of the rubber is used to prevent the cylinder from sliding. The setting of the rubber plate 51 can not only improve the stability of clamping and prevent the cylinder from shifting during processing, but also protect the cylinder surface from being scratched by the clamping plate 42. It is especially suitable for processing cooler cylinders with high surface quality requirements.

[0042] In other embodiments, a mounting sleeve 52 is fixed on the clamping plate 42, and a second elastic element 53 is provided inside the mounting sleeve 52. The second elastic element 53 is a spring. One end of the second elastic element 53 is fixed on the locking rod, and the other end is fixed on the clamping cylinder 1. The buffering effect of the second elastic element 53 can reduce the rigid compression of the cylinder during the clamping process and prevent the cylinder from deforming due to excessive clamping force. At the same time, it can automatically adapt to cylinders of different diameters or shapes, improving the versatility of the equipment.

[0043] In other embodiments, an extension tube 54 is fitted onto the handle 454. The extension tube 54 reduces the torque required to operate the handle 454, making the clamping process more labor-saving. It is especially suitable for processing scenarios that require frequent clamping or large cylinders, and can reduce the labor intensity of operators.

[0044] In other embodiments, the auxiliary support mechanism further includes a base 34, an electric push rod 35, a support column 36, and a third elastic element 37. The electric push rod 35 is fixed on the base 34, and one end of the electric push rod 35 is connected to the support plate 31. One end of the support column 36 is fixed on the support plate 31, and the support plate 31 is provided with a guide hole that cooperates with the support column 36. The third elastic element 37 is a spring, which is sleeved on the support column 36.
