[0002] When installing the belt pressure pulley on the installation shaft, the belt pressure pulley needs to be heated to a certain temperature, and then installed on the installation shaft. During installation, workers may encounter the situation that the belt pressure pulley is not installed properly on the installation shaft. At this time, the belt pressure pulley needs to be removed from the installation shaft, reheated and installed again.

[0003] like Figure 1 As shown, the existing pulley disassembly tooling includes a front baffle 1 and a rear baffle 2, two parallel connection plates 3 are fixed between the front baffle 1 and the rear baffle 2, a jack 6 is installed on the rear baffle 2, and a through hole 11 is opened on the front baffle 1. A connecting shaft 61 is fixed on the piston rod of the jack 6. When the belt pressure wheel 9 on the installation shaft 91 is disassembled, the installation shaft 91 and the belt pressure wheel 9 are placed between the front baffle 1 and the rear baffle 2, and the installation shaft 91 is passed through the through hole 11. Then, the jack 6 applies an external force to the installation shaft 91, so that the installation shaft 91 moves away from the rear baffle 2, so that the installation shaft 91 is separated from the belt pressure wheel 9.

[0004] When the jack 6 applies external force to the installation shaft 91, the belt pressure wheel 9 presses against the front baffle 1, and the front baffle 1 and the connecting plate 3 are easily bent, which affects the next use of the disassembly tool. Utility Model Content

[0005] The embodiment of the utility model provides a belt pressure wheel disassembly tool, which has the technical effect of reducing the possibility of bending of the front baffle plate and the connecting plate.

[0006] The utility model adopts the following technical scheme for disassembling a belt pressure wheel:

[0007] The cam is provided with a plurality of first abutment blocks fixed to the bottom plate, the first abutment blocks are in contact with the side wall of the front baffle plate, and the second abutment blocks are provided on the bottom plate to prevent the front baffle plate from sliding into the groove on the bottom plate.

[0008] Furthermore, a locking rod is fixed to one side of the jack close to the rear baffle, and the locking rod passes through the rear baffle and is threadedly connected with a locking nut.

[0009] Furthermore, a first support rod is fixed on the base plate, a first support block for supporting the mounting shaft is fixed on the top of the first support rod, the first support block is located on the side of the front baffle close to the rear baffle, a second support rod is arranged on the side of the front baffle away from the rear baffle, and a second support block for supporting the mounting shaft is fixed on the top of the second support rod.

[0010] Furthermore, a sliding block is fixed to the bottom of the second support rod, and a sliding groove for the sliding block to slide is provided on the bottom plate, and the length direction of the sliding groove is arranged along the axial direction of the installation shaft.

[0011] Furthermore, a support plate for supporting the jack is fixed between the two connecting plates.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] The bottom of the front baffle is inserted into the first mounting groove, and the bottom of the rear baffle is inserted into the second mounting groove, and a plurality of first abutment blocks are arranged on the side of the front baffle away from the rear baffle. When the jack applies pressure to the mounting shaft, the possibility of deformation of the front baffle and the connecting plate can be reduced, thereby increasing the stability of the belt pressure pulley disassembly tooling and increasing the service life of the belt pressure pulley disassembly tooling.
