In order to achieve the above object, the present invention provides the following technical solutions:

a device for replacing a grinding wheel spindle leather bag comprises a supporting body, wherein a screw rod channel is arranged at the front end of the supporting body along the length direction of the supporting body, a first gasket is arranged on the end face of the front end of the supporting body, a screw rod is further arranged at the front end of the supporting body, the front end of the screw rod is connected with the rear end of a clamping and positioning block, two sides of the front end of the clamping and positioning block protrude forwards to form a U-shaped clamping groove, the axial direction of the clamping groove is perpendicular to the axial direction of the screw rod, the clamping groove penetrates through the front end face of the clamping and positioning block, the rear end of the screw rod penetrates through the first gasket and extends into the screw rod channel, an axial sliding pair is arranged between the screw rod and the screw rod channel, an adjusting nut is arranged on the screw rod, and the adjusting nut is arranged between the first gasket and the clamping and positioning block.

Furthermore, a second gasket is arranged on the end face of the rear end of the supporting body.

Furthermore, the support body is a cylinder or a cuboid.

The working principle is as follows: only need demolish the steel ring that is used for fastening the leather bag, just can directly change the leather bag, promote the steel ring through this device, can accomplish the fastening in impressing the steel ring in the corresponding groove, saved processes such as demolising the main shaft, recalibrate.

Compared with the prior art, the beneficial effects of the utility model are that: the labor and time for replacing the leather bag are effectively saved.

Detailed Description

Example 1

Referring to fig. 1 and fig. 2, the present invention provides a technical solution:

a device for replacing a grinding wheel spindle leather bag comprises a supporting body 1 and is characterized in that: the front end of the support body 1 is provided with a screw rod channel 2 along the length direction, the end face of the front end of the support body 1 is provided with a first gasket 3, the front end of the support body 1 is further provided with a screw rod 4, the front end of the screw rod 4 is connected with the rear end of a clamping and positioning block 5, two sides of the front end of the clamping and positioning block 5 protrude forwards to form a U-shaped clamping groove 6, the axial direction of the clamping groove 6 is perpendicular to the axial direction of the screw rod 4, the clamping groove 6 penetrates through the front end face of the clamping and positioning block 5, the rear end of the screw rod 4 penetrates through the first gasket 3 and extends into the screw rod channel 2, an axial sliding pair is arranged between the screw rod 4 and the screw rod channel, the screw rod 4 is provided with an adjusting nut 7, and the adjusting nut 7 is arranged between the first gasket 3 and the clamping and positioning block 5.

Further, a second spacer 8 is provided on the end surface of the rear end of the support body 1.

Further, the support body 1 is a cylinder or a cuboid.

Specifically, the support body 1 is made of a flexible material, such as a nylon rod, or the support body 1 is made of a rigid material, such as stainless steel, and the flexible second gasket 8 is arranged at the rear end of the support body 1, so that the main shaft is prevented from being damaged when the rear end of the support body 1 is in contact with the main shaft.

In particular, the first washer 3 serves to prevent the adjusting nut 7 and the screw 4 from damaging the support body 1.

The working process of the embodiment:

the opening of the groove of the box body faces the axis of the main shaft 9, the leather bag has certain thickness and strength, and the steel ring also has certain length to ensure that the leather bag can be reliably and effectively fixed in the groove of the box body.

The process of replacing the leather bag of the device is as follows:

step 1, removing an old steel ring in an installation groove at the periphery of a main shaft 9, and directly removing an old leather bag after the old leather bag loses the support of the old steel ring;

step 2, placing the edge of the new leather bag at a position corresponding to the mounting groove, and annularly placing a new steel ring 10 at the inner side of the leather bag;

step 3, using five tools ABCDE as one set, placing the tools ABCDE around a main shaft 9 as shown in figure 2, sleeving a clamping groove 6 on the outer side of a steel ring 10 to prevent the tools from slipping, wherein Q is the section of the steel ring 10;
