Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of supporting cushion blocks, in particular to a supporting cushion block with controllable cutting torque. Background Art
[0002] During the processing of thin-walled parts, due to the local deformation of the cutting tool during the cutting process, support pads are needed for auxiliary support. However, rigid support may lead to inadequate support or support deformation. Therefore, semi-suspended support is required during the processing to avoid overcutting or undercutting.
[0003] During the use of the support pad, a spring is installed on the inside of the support pad. When the spring is deformed during cutting, the deformation will cause the processing part to offset for buffering, thereby avoiding the deformation of the support. However, the pressure generated when the processing support column is used is different. When the buffering force provided by the buffer device is too low, the support device will shake when used. The shaking of the support device will also affect the cutting effect of the tool. For this reason, we propose a support pad with controllable cutting torque. Utility Model Content
[0004] In view of the shortcomings of the existing support pads with controllable cutting torque, the utility model provides a support pad with controllable cutting torque, which has a disc spring installed on the inner side of a tightening nut. By rotating the tightening nut, the tightening nut applies pressure to the disc spring. At the same time, the pressure borne by the disc spring is changed, which can improve the adjustable buffering force of the equipment, thereby solving the problems raised in the above-mentioned background technology.
[0005] The utility model provides the following technical solution: a supporting pad with controllable cutting torque, comprising an outer shell, a supporting pad being movably sleeved inside the front end of the outer shell, a gasket being installed on one side of the supporting pad, a disc spring being sleeved inside the outer shell in sequence, a tightening nut being threadedly installed at the end of the outer shell, a mounting hole being provided inside the tightening nut, a positioning hole being provided outside the outer shell, a positioning pin being movably sleeved inside the mounting hole, and an inner limiting plate being fixedly connected to one end of the gasket.
[0006] Preferably, the gasket is attached to one end of the support pad, and the end of the support pad extends to the inside of the end of the shell.
[0007] Preferably, four groups of disc springs are installed between the gasket and the tightening nut, the disc springs are arranged in a conical disc shape, and the disc springs are installed forward and reversely to form a group of disc spring units.
[0008] Preferably, the positioning holes are opened downward at equal intervals on the outside of the housing, and the positioning pins pass through the inside of the positioning holes and the mounting holes in sequence.
[0009] Preferably, the inner limiting plate is installed on the inner side of the tightening nut and one side of the gasket, and the inner limiting plate is sleeved inside the disc spring.
[0010] Preferably, the exterior of the tightening nut is a hexagonal structure, and the tightening nut extends to the interior of one end of the housing.
[0011] Compared with the existing support pads with controllable cutting torque, the utility model has the following beneficial effects:
[0012] 1. The support pad with controllable cutting torque controls the dimensional deviation caused by the local deformation of the parts during the processing of thin-walled parts, especially during the precision processing. Due to the use of disc spring structure, its rigidity is better than the support of spring or hydraulic structure; at the same time, the adjustability of the invention will effectively realize the semi-suspended support of the parts, and the support points can be added at will according to the needs; at the same time, the controllable torque support pad of the invention can also be used for semi-suspended support during the installation process of large thin-walled structural parts to reduce the deformation caused by the installation.
[0013] 2. The support pad with controllable cutting torque applies pressure to the disc spring by rotating the tightening nut, and at the same time controls the alignment between the mounting hole and the locating hole. A locating pin is installed through the inside of the mounting hole and the locating hole. The locating pin drives the tightening nut to limit the position inside the shell to avoid excessive pressure, which may cause wear on the external thread groove of the tightening nut.

[0022] refer to Figure 2 The gasket 3 is attached to one end of the support block 2, and the end of the support block 2 extends to the inside of the end of the shell 1. After the support block 2 extends to the inside of the shell 1, and the outside of the support block 2 is in contact with the tool for support, when the equipment is deformed during processing, the support block 2 can be buffered inside the shell 1 through the disc spring 4.
[0023] refer to Figure 3 and Figure 4 Four groups of disc springs 4 are installed between the gasket 3 and the tightening nut 5. The disc springs 4 are arranged in a conical disc shape, and the disc springs 4 are installed in both directions as a group of disc spring units. By controlling the disc springs 4 to be stacked and placed between the gasket 3 and the tightening nut 5 in sequence, and rotating the tightening nut 5 at the same time, the tightening nut 5 can adjust the pressure provided by the disc springs 4.

By rotating the tightening nut 5, the pressure applied by the disc spring 4 is adjusted, and the positioning pins 8 are passed through the inside of the mounting holes 6 and the positioning holes 7 at the same time. The positioning pins 8 limit the position of the tightening nut 5 inside the shell 1 to avoid excessive pressure between the tightening nut 5 and the shell 1, which may cause wear of the internal threads of the shell 1.
[0025] refer to Figure 2 The inner limiting plate 9 is installed on the inner side of the tightening nut 5 and one side of the gasket 3.

[0027] Working principle: When in use, tighten the nut 5 with a torque wrench, so that the tightening nut 5 moves inward. At the same time, a positioning pin 8 is installed inside the positioning hole 7 to limit the position of the tightening nut 5 inside the housing 1, thereby compressing the disc spring 4 to reach a preset torque.
