Problems solved by technology

At present, in the process of brake drum processing, vertical CNC lathes are used, the brake drum is fixed by hydraulic claws, and then the rough turning and finishing turning are carried out by tools, but the existing mechanism for fixing the brake drum, On the one hand, because only the hydraulic claws are clamped vigorously, a friction force is generated to keep the brake drum from moving up and down, and there is no independent device to further prevent the brake drum from moving up and down. When the tool is processed from top to bottom, it is often There will be a downward pressure. When the friction force between the outer wall of the brake drum and the contact surface o

Embodiment 1

[0036] as attached Figures 1 to 3 As shown, the positioning and anti-sinking device for processing automobile brake drums in this embodiment is installed on the workbench 2 of the ZL2-550 vertical lathe, and two groups of claws are arranged symmetrically on the workbench 2 3. It also includes two sets of anti-sinking mechanisms 4 that are symmetrically arranged and staggered with the positions of the two sets of claws. The anti-sinking mechanism includes a base 41, a height adjustment part 42, a length adjustment part 43 and a support part 44; the support The portion 44 is arranged at one end of the length adjusting portion 43 close to the center of the workbench 2, the opposite end of the length adjusting portion 43 is connected to the upper end of the height adjusting portion 42, and the lower end of the height adjusting portion 42 is connected to the The base 41; the length adjustment part 43 is set from one end connected to the height adjustment part 42 to one end connect...

Embodiment 2

[0040] as attached Figure 4As shown, different from Embodiment 1, the present Embodiment 2 is provided with three sets of identical anti-sinking mechanisms 4, which are arranged at an angle of 120 degrees between two pairs of spaces other than the two sets of claws 3 on the workbench 2; Three sets of anti-sinking mechanisms 4 are used obliquely on the side wall of the bottom of the brake drum 1, and the force can be adjusted to point to a position closer to the body center of the product. The triangular force is more stable and uniform, and can be further improved. Reduce the error generated during processing and avoid the possibility of local sinking deviation of the brake drum 1;

Embodiment 3

[0042] as attached Figure 5 As shown, on the basis of Embodiment 2, the included angle d between the inclined working surface 46 and the support portion 44 in Embodiment 3 is 10 degrees, and the convex portion of the arc surface is evenly arranged on the inclined working surface 46 , reduce the probability of not fitting with the contact surface, and reduce the error; the length adjustment part 43 is also provided with an inclination angle adjustment mechanism, which can be superimposed by connecting the length adjustment part 43 and the height adjustment part 42 with an existing damping Realized by means of a rotating shaft, the inclination angle of the length adjusting part 43 is controlled between 30 degrees and 80 degrees, which further improves the operation convenience and product adaptability of the anti-sinking mechanism.

[0043] as attached Figure 6 , Table 1, Table 2 and Table 3, ten brake drums 1 were selected at random respectively, processed by lathes without ...

Abstract

The invention discloses a positioning anti-sinking device for processing an automobile brake drum and a processing method thereof. The device is arranged on a workbench of a vertical lathe, two sets of clamping claws are symmetrically arranged on the workbench, the device comprises two or more sets of anti-sinking mechanisms, and the anti-sinking mechanisms comprises bases, height adjustment parts, length adjustment parts and supporting parts. The positioning anti-sinking device for processing the automobile brake drum is novel in structure and practical in function, the anti-sinking mechanisms are arranged on the workbench, pressure which is generated by a cutting tool from top to bottom can be effectively inhibited, sinking or local shifting of products can be avoided, then, processing errors which are generated due to sinking or shifting are avoided, and the product quality is improved; the lower portion of the base is connected with the upper end surface of the workbench through arail, and the rail is arranged in the radial direction of the workbench; the anti-sinking mechanisms can totally move along the workbench in the radial direction, the position where the supporting parts act on the bottoms of products is adjusted, and the positioning anti-sinking device meets processing operation requirements of more products.

Description

technical field [0001] The invention belongs to the field of brake drum processing equipment, and in particular relates to a positioning anti-sinking device for processing automobile brake drums and a processing method thereof. Background technique [0002] Automobile brakes are components used in the braking system to generate braking force that hinders vehicle movement or movement tendency. It can be divided into two categories: drum type and disc type; The surface is a cylindrical surface, and its drum body shape is similar to a basin. One end is the bottom of the brake drum, and the other end is open and usually provided with a rim. At present, in the process of brake drum processing, vertical CNC lathes are used, the brake drum is fixed by hydraulic claws, and then the rough turning and finishing turning are carried out by tools, but the existing mechanism for fixing the brake drum, On the one hand, because only the hydraulic claws are clamped vigorously, a friction fo...
