Description

Technical Field

[0001] This utility model relates to the field of lifting tools, and in particular to a high-precision lifting tool for machine housings. Background Technology

[0002] During the assembly of high-precision machine housing parts, hoisting is required. Currently, hoisting is achieved directly by hooking a hook onto the annular edge of the top of the housing (see reference). Figure 1 ).

[0003] The above-mentioned hoisting process has the following technical problems: 1. Because the hook is in direct contact with the workpiece, the workpiece surface is prone to serious bumps and scratches during the hoisting process, resulting in a large amount of workpiece rework. 2. During the hoisting process, the contact area between the hook and the workpiece is small, and there is a risk that the hook will fall off, making the hoisting process unstable; 3. Due to limitations in the size and shape of the hook, the types of workpieces that can be lifted are restricted. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a high-precision lifting tool for hoisting machine housings.

[0005] The high-precision lifting tool for hoisting machine casings provided in this application adopts the following technical solution: A high-precision lifting tool for machine housing includes a base plate, a top plate, a connecting plate, and a lifting ring. The base plate and the top plate are both horizontally arranged, and the connecting plate is vertically arranged. The connecting plate is welded to both the base plate and the top plate. A lifting groove is formed between the base plate and the top plate. The annular edge of the workpiece is located in the lifting groove. The lifting ring is fixedly welded to the top surface of the top plate, and the lifting hook hooks onto the lifting ring.

[0006] Preferably, the axial direction of the lifting ring is parallel to the length direction of the top plate.

[0007] Preferably, the lifting ring is located at the middle of the length direction of the top plate.

[0008] Preferably, the top surface of the lifting ring is arc-shaped.

[0009] Preferably, the bottom end of the connecting plate extends below the bottom plate.

[0010] Preferably, the top end of the connecting plate extends above the top plate.

[0011] Preferably, the side of the connecting plate away from the workpiece is fixedly welded with reinforcing ribs.

[0012] Preferably, the bottom surface of the reinforcing rib is flush with the bottom surface of the connecting plate, the top surface of the reinforcing rib is welded to the lifting ring, and the bottom surface of the lifting ring is provided with a notch for the top of the connecting plate to be engaged.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. The hook directly hooks onto the lifting ring of the lifting device, and the annular edge of the workpiece is located in the lifting groove of the lifting device. The hook does not directly contact the workpiece, avoiding bumps and scratches on the workpiece surface and reducing the time for workpiece rework. 2. The large contact area between the lifting device and the workpiece improves the stability of the lifting process; 3. The workpiece is supported by the ring-shaped edge of the base plate of the lifting device. The types of workpieces that can be lifted are not restricted by the size and shape of the hook, and the range of applicable workpieces is wide. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0020] This application discloses a high-precision lifting tool for hoisting machine casings.

[0021] Reference Figure 2-4 The lifting tool for high-precision machine housing includes a base plate 1, a top plate 2, a connecting plate 3, and a lifting ring 4. The base plate 1 and the top plate 2 are both horizontally set, and the connecting plate 3 is vertically set. The connecting plate 3 is welded to both the base plate 1 and the top plate 2. A lifting groove 5 is formed between the base plate 1 and the top plate 2. The annular edge 8 of the workpiece is located in the lifting groove 5. The lifting ring 4 is fixedly welded to the top surface of the top plate 2, and the hook 7 hooks the lifting ring 4.

[0022] The hook 7 directly hooks onto the lifting ring 4 of the lifting device, and the annular edge 8 of the workpiece is located in the lifting groove 5 of the lifting device. The hook 7 does not directly contact the workpiece, avoiding bumps and scratches on the workpiece surface and reducing the time for workpiece rework.

[0023] The axis of lifting ring 4 is parallel to the length of top plate 2. The lifting devices are distributed at different positions on the workpiece according to actual needs to ensure uniform force distribution during the lifting process. The large contact area between the lifting devices and the workpiece improves the stability of the lifting process.

[0024] The workpiece is supported by the annular edge 8 of the base plate 1 of the lifting device. The types of workpieces that can be lifted are not restricted by the size and shape of the hook 7, and the range of applicable workpieces is wide.

[0025] The lifting ring 4 is located in the middle of the length of the top plate 2 to ensure the uniformity of force on each lifting device.

[0026] The top surface of the lifting ring 4 is arc-shaped to avoid accidental injury during manual operation.

[0027] The bottom end of the connecting plate 3 extends below the bottom plate 1, and the top end of the connecting plate 3 extends above the top plate 2. A reinforcing rib 6 is fixedly welded to the side of the connecting plate 3 away from the workpiece. The reinforcing rib 6 is located in the middle of the length direction of the connecting plate 3. The bottom surface of the reinforcing rib 6 is flush with the bottom surface of the connecting plate 3. The top end of the reinforcing rib 6 is welded to the lifting ring 4. The bottom surface of the lifting ring 4 is provided with a notch for the top end of the connecting plate 3 to be engaged.

[0028] The reinforcing rib 6 is fixedly welded to the connecting plate 3 and the lifting ring 4 to improve the overall structural strength of the lifting device.

[0029] The implementation principle of a high-precision hoisting tool for machine housing in this application embodiment is as follows: during hoisting, the annular edge 8 of the workpiece is inserted into the hoisting groove 5 of the hoisting tool, and the hoisting tools are distributed at different positions of the workpiece according to actual needs. For example, for annular workpieces, multiple hoisting tools are set at equal intervals along the circumference of the workpiece, and then the hook 7 is hooked onto the lifting ring 4 of the hoisting tool for hoisting.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
