Benefits of technology

This new technology makes it possible for machines like lathes to automatically adjust their rolls based upon its own design without requiring expensive machining processes. It also allows for easy changes when there are slight variations between different shapes/positions caused due to imperfections such as uneven surfaces. Additionally, this technology doesn't use any special tools at all, making them suitable for various applications where they were previously needed.

Problems solved by technology

Technics discusses various techniques that help prevent defects from happening when manufacturing products made up of randomly shaping metallurgies. These include milling processes like tumbler machining, laser drilling, grinding tools, and others. However, current solutions have limitations due to their complexity and costly maintenance procedures. Additionally, they require specific conditions under different circumstances depending upon factors like temperature, humidity, and lubricant type.

Embodiment 1

[0031] This embodiment is carried out on a common lathe.

[0032] A gravity-type adjustable rolling tool is composed of a gravity reversing mechanism, a gravity traction mechanism and a roller-type rolling head.

[0033] Depend on figure 1 , 2 It can be seen that the gravity reversing mechanism is composed of three sets of fixed pulleys fixed on the end cover with square hole screws. The connection relationship is as follows: the three pulley frames 7 are fixed at intervals of 120 degrees along the circumferential direction of the end cover 18 through three square hole screws 4 and three nuts 5; Form three groups of fixed pulley mechanisms fixed on the end cover, and the direction of force can be changed by matching the three groups of fixed pulley mechanisms with the traction rope 11.

[0034] The gravity traction mechanism is composed of a heavy object suspension rope 13, a safety nut 14, a gravity traction ring 15, a traction rope 11, a sleeve 12, a thrust ring 17, a tra...

Embodiment 2

[0039] In this embodiment, on the basis of Embodiment 1, the roller-type rolling head is replaced with a ball-type rolling head, and the ball-type rolling head is fixed on the rolling shaft by three hexagon socket head cap screws 2 with a circumferential distance of 120 degrees. 20 on. The structure diagram of the ball rolling head is as follows: Figure 9 As shown, the ball rolling head is made up of a ball rolling head seat 36, a screw 37, a retaining cap 38, a small ball 39, a large ball 40, a rubber gasket 41 and a spring washer 42. Its connection form is as follows: Figure 10 As shown, a circle of small balls is installed along the bottom periphery of the stepped hole of the ball-type rolling head seat 36, and a large ball 40 is placed on the small ball. The stepped holes are equipped with rubber gaskets 41 and spring gaskets 42 in sequence. Install retaining cap 38 outside small ball 39, rubber washer 41 and spring washer 42, and be that retaining cap 38 is fixed on ...

Abstract

The invention discloses a gravity-type adjustable rolling too, which is formed by a gravity reversing mechanism, a gravity drawing mechanism and a roller-type rolling head or ball-type rolling head, wherein the gravity reversing mechanism realizes the goal of reversing through three fixed pulleys and matched drawing ropes; the gravity drawing mechanism generates constant pulling force through the suspended weight and converts the pulling force of the weight into rolling force to a workpiece through the gravity reversing mechanism; and the roller-type rolling head or ball-type rolling head is fixedly connected on a rolling shaft in the gravity drawing mechanism and directly rolls the workpiece. By adopting the three mechanisms, the rolling tool can ensure the rolling force to be constant when the surface of the workpiece fluctuates slightly or severely, and the rolling force can be conveniently and rapidly varied through varying the mass of the suspended weight. The rolling tool has the advantages of simple structure, convenient manufacturing and low cost and can be directly used on common lathes.
