Description

Technical Field

[0001] The utility model relates to the technical field of lifting and hoisting, and more specifically to a full-electric expansion and rolling device. Background Art

[0002] At present, the main lifting equipment in many workshops is still gantry cranes, which is very inconvenient for lifting some uncommon parts.

[0003] Some products are cylindrical in shape, but they are long, have a large diameter, and have a thin outer wall. The operations required are lifting and rolling.

[0004] The technical difficulties are as follows:

[0005] 1. The outer surface must not be damaged: the construction surface of the product is on the outer surface.

[0006] 2. The product needs to be rolled: The outer circle of the product is relatively large, and manual construction can only be carried out half and half, so it must be rolled.

[0007] 3. The product cannot be deformed: The technical requirements of the product stipulate that it cannot be deformed. At the same time, deformation will also affect the construction of the outer surface.

[0008] 4. The tooling needs to be replaced flexibly: The gantry truck also has other functions, so this tooling needs to be taken down when producing other products. Utility Model Content

[0009] The purpose of the utility model is to provide a fully electric expansion and rolling device for hoisting large cylindrical barrels, especially thin-walled parts, in view of the shortcomings of the prior art.

[0010] A fully electric expansion and rolling device includes a power component and an expander tooling arranged on a sling body, the expander tooling includes a nut, an expander body and a screw rod for connection, a first support rod and a second support rod connected to the nut, a support plate connected to the first support rod and the second support rod, a connecting rod on the expander body, the connecting rod is hingedly connected to the first support rod and the second support rod, and drives the support plate to expand and contract; power is input by the power component to perform rotation or expansion action of the expander tooling.

[0011] The utility model has a reasonable structure and is a special device for hoisting large cylindrical barrels (thin-walled parts). The tooling is used to open the inside of the barrel so that the thin-walled parts will not be deformed during the hoisting process; that is, products with large diameters and thin walls can also be hoisted.

[0012] As a further improvement and supplement to the above solution, the utility model also includes the following additional technical features:

[0013] The power components are the sleeve, the mandrel in the sleeve, and the first synchronous pulley on one side of the power mechanism. The first synchronous belt drives the second synchronous pulley on the sleeve to rotate the expander tooling; the first synchronous pulley on the power mechanism on the other side drives the third synchronous pulley on the mandrel through the second synchronous belt to tighten the expander tooling. The transmission is stable and reliable.

[0014] The power mechanism is a connected reducer and a servo motor. The servo motor can be used for products with various diameters and has a wider range of applications.

[0015] The nut is a rotating blade structure, and the support plate is an arc-shaped structure, which is easy to rotate and has a good fit with the product.

[0016] The sleeve is provided with a single-row angular contact bearing and an angular contact ball bearing; the two ends of the mandrel are provided with deep groove ball bearings. The support is effectively provided to ensure the life of the sleeve and the mandrel. The servo motor is used, and it can be used for products of various diameters, and has a wider range of applications.

[0017] One side of the sleeve is fixed by a first locking nut. The structure is reasonable and the locking is safe and reliable.

[0018] The sling body is a C-shaped structure, which is reasonable and convenient to put into the product.

[0019] The following beneficial effects can be achieved by using the utility model:

[0020] The utility model has a reasonable structure and is a special device for hoisting large cylindrical barrels (thin-walled parts). The tooling is used to open the inside of the barrel so that the thin-walled parts will not be deformed during the hoisting process; that is, products with large diameters and thin walls can also be hoisted.

[0021] This device combines the internal expansion device with the rolling device to avoid surface damage to the product caused by multiple lifting and product rotation. It breaks through the technical difficulties: it can complete the lifting and rolling functions at the same time.

[0022] The use of servo motors can be used for products of various diameters and has a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5 As shown, the utility model is a fully electric expansion and rolling device.

[0030] The all-electric expansion and rolling device described in this embodiment includes a power component 1 and an expander tool 2 arranged on the sling body 5, and the expander tool 2 includes a nut 7, an expander body 12 and a screw 13 for connection, and the screw 13 passes through the expander body 12 and is threadedly connected with the nut 7. The first support rod 8 and the second support rod 9 connected to the nut 7, the support plate 10 connected to the first support rod 8 and the second support rod 9, and the connecting rod 11 on the expander body 12, the connecting rod 11 is hingedly connected with the first support rod 8 and the second support rod 9, and drives the support plate 10 to expand and contract; the power is input by the power component 1 to rotate or expand the expander tool 2.

[0031] Furthermore, the power component 1 is a sleeve 3 and a core rod 21 in the sleeve 3. The sleeve 3 passes through the sling body 5 and is clamped on the nut 7. A screw 13 is clamped at one end of the sleeve 3, and a core rod 21 is sleeved at the other end. The first synchronous pulley 27 on the power mechanism on one side drives the second synchronous pulley 17 on the sleeve 3 through the first synchronous belt 16, which is used for the rotation of the expander tooling 2. The first synchronous pulley 27 on the power mechanism on the other side drives the third synchronous pulley 25 on the core rod 21 through the second synchronous belt 26, which is used for the expansion of the expander tooling 2.

[0032] Furthermore, the power mechanism is a connected reducer 18 and a servo motor 19. The reducer 18 and the servo motor 19 are fixed on both sides of the sling body 5 through a support frame 28, and the support frame 28 is provided with reinforcing ribs.

[0033] Furthermore, the nut 7 is a rotating blade structure, and the outer shape of the support plate 10 is an arc structure.

[0034] Furthermore, the sleeve 3 is provided with a single-row angular contact bearing 4 and an angular contact ball bearing 20 ; and deep groove ball bearings 15 are provided at both ends of the core rod 21 .

[0035] The sleeve 3 is provided with a single-row angular contact bearing 4 on the hanger body 5 on the nut 7 side and is fixed by a first bearing retaining ring 6 ; the sleeve 3 is provided with an angular contact ball bearing 20 on the opposite side of the nut 7 .

[0040] 1. Preparation

[0041] The nut 7 is close to the expander body 12, and the first support rod 8 and the second support rod 9 drive the support plate 10 to be in a relaxed state.

[0042] 2. Internal expansion action

[0043] When tightening:

[0044] Put the C-shaped hook into the product cavity, and the servo motor and reducer at the (tail end) transmit the force to the second synchronous belt 26 through the first synchronous pulley 27; then transmit it to the third synchronous pulley 25, and then drive the core rod 21 to rotate. The rotation of the core rod 21 drives the screw 13 of the tooling part to rotate; the screw 13 pushes the nut 7 forward; the first support rod 8 and the second support rod 9 on the nut 7 gradually open until they are completely attached to the inner surface of the product.

[0045] 3. Rotational movement

[0047] The rotation can be performed when the tool is empty or fully loaded (with product on the tooling).

[0048] The above are preferred implementations of the present invention, which do not limit the protection scope of the present invention. Any modifications and improvements made by those skilled in the art based on the design ideas of the present invention should be regarded as within the protection scope of the present invention.
