Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum industry, in particular to a vacuum industry expansion sleeve disassembly device. Background Art
[0002] The expansion sleeve disassembly device is mainly used in the expansion sleeve disassembly link of a specific series of vacuum pumps in the vacuum industry. When disassembling the expansion sleeve, the disassembly personnel often use violence to "smoothly" disassemble and pull out the expansion sleeve. However, due to the uneven force points of the expansion sleeve during forced disassembly, the expansion sleeve will inevitably swing on the shaft for disassembly, and it is impossible to achieve true smoothness. Therefore, it is very easy for the expansion sleeve to be damaged during the forced disassembly process, or the disassembly will be skewed and eventually damage the parts. Utility Model Content
[0003] The utility model provides a vacuum industry expansion sleeve disassembly device, which can overcome certain defects of the prior art.
[0004] According to the utility model, a vacuum industry expansion sleeve disassembly device comprises a connecting rod part and an external support part;
[0005] The connecting rod part includes a rotating handle, a connecting rod is connected below the rotating handle, and a connecting head is rotatably connected below the connecting rod;
[0006] The external support part includes a bracket, a screw hole is provided in the middle of the bracket, and an external thread is provided on the connecting rod, and the external thread cooperates with the screw hole; support rods are respectively connected to the bottom of the two ends of the bracket, and a support plate is connected under the two support rods. The support plate is provided with a card slot, and the card slot is used to clamp the sleeve at the bottom of the expansion sleeve.
[0007] Preferably, a thrust bearing is provided in the connecting head, and the thrust bearing is connected to the connecting rod.
[0008] Preferably, the thrust bearing is installed in the connecting head via a first retaining spring and a second retaining spring.
[0009] Preferably, the clamping groove comprises a semicircular groove, and a semicircular clamping ring is provided at the bottom of the groove, and the clamping ring is used to clamp at the bottom corner of the expansion sleeve.
[0010] Preferably, the slot, connecting rod, thrust bearing and connecting head are coaxial.
[0011] The utility model clamps the card slot at the bottom of the expansion sleeve, and the connecting head is against the top of the component covered by the expansion sleeve. Then, the handle is rotated to push the connecting head downward continuously, so that the support plate together with the expansion sleeve clamped thereon continuously translates upward until the expansion sleeve is disassembled. Compared with violent manual disassembly, the utility model is more labor-saving, more convenient, very smooth, and not easy to damage the expansion sleeve and parts.

[0015] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.
[0016] Example
[0017] like Figure 1 and Figure 2 As shown, this embodiment provides a vacuum industry expansion sleeve disassembly device, which includes a connecting rod part and an external support part;
[0018] The connecting rod part includes a rotating handle 1, a connecting rod 3 is connected below the rotating handle 1, and a connecting head 8 is rotatably connected below the connecting rod 3;
[0019] The external support part includes a bracket 2, a screw hole is provided in the middle of the bracket 2, and an external thread is provided on the connecting rod 3, and the external thread cooperates with the screw hole; support rods 4 are respectively connected to the bottom of the two ends of the bracket 2, and a support plate 9 is connected under the two support rods 4. A card slot 91 is provided on the support plate 9, and the card slot 91 is used to clamp the sleeve at the bottom of the expansion sleeve.
[0020] A thrust bearing 7 is arranged in the connector 8, and the thrust bearing 7 is connected to the connecting rod 3. By setting the thrust bearing 7, the connector 8 can not rotate with the rotating handle 1, so that the connector 8 can better abut against the top of the component covered by the expansion sleeve, and it is not easy to damage the top of the component covered by the expansion sleeve.
[0021] The thrust bearing 7 is installed in the connector 8 through the first retaining spring 5 and the second retaining spring 6. The first retaining spring 5 is clamped in the connector 8, and the second retaining spring 6 is installed at the bottom end of the connecting rod 3 and is clamped in the thrust bearing 7.
[0022] The clamping groove 91 includes a semicircular groove, and a semicircular clamping ring 92 is provided at the bottom of the groove hole, and the clamping ring 92 is used to clamp at the bottom corner of the expansion sleeve. By setting the clamping ring 92 in the clamping groove 91, the clamping ring 92 can be clamped at the bottom corner of the expansion sleeve, so that the clamping groove 91 can be better clamped on the expansion sleeve.
[0023] The slot 91, the connecting rod 3, the thrust bearing 7 and the connecting head 8 are coaxial.
[0024] By locking the slot 91 at the bottom of the expansion sleeve, the connecting head 8 is against the top of the component covered by the expansion sleeve, and then rotating the handle 1 to push the connecting head 8 downward continuously, so that the support plate 9 together with the expansion sleeve stuck thereon continuously translates upward until the expansion sleeve is disassembled. Compared with violent manual disassembly, it is more labor-saving, more convenient, and very smooth, and it is not easy to damage the expansion sleeve and parts.
[0025] like Figure 3 , which is a schematic diagram of the cooperation between the disassembly device and the expansion sleeve, wherein the component clamped by the support plate 9 is the expansion sleeve.
[0026] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
