Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, in particular to a clamping and fixing mechanism for processing automobile brake drums. Background Art

[0002] The brake drum is a friction pair of drum brakes. In addition to the strength and rigidity required as a component, it should also have the highest and most stable friction coefficient, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. The basic shape of the brake drum is drum-shaped. The brake drum should have sufficient wall thickness and cast circumferential or axial reinforcement ribs near the opening on the outer surface to improve strength. These reinforcement ribs also play a role in heat dissipation, which can reduce the temperature of the friction surface, shorten the cooling time of the brake, and increase the energy capacity by 35%-40%. During the processing of the brake drum, the brake drum needs to be clamped and fixed to avoid shaking during assembly.

[0003] For example, a clamping and fixing mechanism for automobile brake drum processing disclosed in a Chinese patent document (publication number: CN217143707U) can drive the clamping plate to clamp and fix the automobile brake drum through the setting of the threaded rod, thereby facilitating the stable assembly of the brake drum. However, in this clamping state, only one surface of the automobile brake drum can be assembled. If other surfaces need to be assembled, the automobile brake drum needs to be unclamped and turned over and then clamped and fixed again, which wastes time and reduces work efficiency.

[0024] The outer surface of the bidirectional threaded rod 5 is threadedly sleeved with symmetrically distributed mounting blocks 6, and the inner walls of the two mounting blocks 6 are movably sleeved with the outer surface of the limiting rod 4. The cooperation between the limiting rod 4 and the bidirectional threaded rod 5 allows the mounting block 6 to move left and right. A mounting hole 7 is provided on one side surface of the mounting block 6, and a mounting rod 8 is installed on the inner wall of the mounting hole 7 through a bearing. An arc-shaped clamping block 9 is fixedly connected to one end of the mounting rod 8, and rubber anti-skid pads are fixedly installed on the opposite surfaces of the two arc-shaped clamping blocks 9 to prevent the automobile brake drum from slipping. The other end of one of the mounting rods 8 penetrates and extends to one side surface of one of the mounting blocks 6, and the other end of one of the mounting rods 8 is fixedly connected to a driving disk 10, and the outer surface of the driving disk 10 is provided with driving grooves 11 distributed in a ring array, and the outer surface of the driving disk 10 is provided with limiting grooves 12 distributed in a ring array.

[0025] One end of the bidirectional threaded rod 5 is fixedly connected to a rotating disk 13, and a driving motor 14 is fixedly installed on the other side surface of one of the mounting blocks 6. The output shaft of the driving motor 14 is fixedly installed with a rotating shaft 15 through a coupling. One end of the rotating shaft 15 penetrates and extends to one side surface of one of the mounting blocks 6, and one end of the rotating shaft 15 is fixedly connected to a rectangular sleeve 16, and a spring 17 is fixedly connected to the front inner wall of the rectangular sleeve 16.

[0026] A rectangular block 18 is fixedly connected to one end of the spring 17, and the outer surface of the rectangular block 18 is movably connected to the inner wall of the rectangular sleeve 16. A toggle block 19 is fixedly connected to one side surface of the rectangular block 18. The toggle block 19 can drive the drive disk 10 to rotate through the cooperation of the drive groove 11 and the spring 17. The upper and lower surfaces of the rectangular sleeve 16 are fixedly connected to symmetrically distributed support blocks 20, and one end of the two support blocks 20 is fixedly connected to an arc-shaped limit block 21, and the outer surface of the arc-shaped limit block 21 contacts the inner wall of one of the limit grooves 12.

[0027] By clamping and fixing the automobile brake drum, the automobile brake drum will not shake during the assembly process, and after one side is assembled, the automobile brake drum can be rotated to facilitate continued assembly of other sides, avoiding frequent disassembly and installation, saving time and improving work efficiency.

[0028] Working principle: Step 1, place the automobile brake drum to be assembled between the two arc-shaped clamping blocks 9, rotate the rotating disk 13, the rotation of the rotating disk 13 drives the bidirectional threaded rod 5 to rotate, the rotation of the bidirectional threaded rod 5 and the cooperation of the limit rod 4 drive the two mounting blocks 6 to move relative to each other, the relative movement of the two mounting blocks 6 drives the two arc-shaped clamping blocks 9 to move relative to each other through the mounting rod 8, the relative movement of the arc-shaped clamping blocks 9 makes the automobile brake drum clamped and fixed, and now one side of the automobile brake drum can be assembled;

[0029] Step 2, when one side of the automobile brake drum is assembled, start the drive motor 14, and the drive motor 14 drives the rotating shaft 15 to rotate one circle through the coupling. The rotation of the rotating shaft 15 drives the rectangular sleeve 16 to rotate, and the rotation of the rectangular sleeve 16 drives the toggle block 19 to rotate through the rectangular block 18. The rotation of the rectangular sleeve 16 also drives the arc-shaped limit block 21 to rotate through the support block 20. The rotation of the arc-shaped limit block 21 causes the outer surface of the arc-shaped limit block 21 to be separated from the inner wall of one of the limit grooves 12. At the same time, the rotation of the toggle block 19 drives the drive disk 10 to rotate through the cooperation of the drive groove 11 and the spring 17 The rotation of the driving disk 10 drives the arc-shaped clamping block 9 to rotate through the mounting rod 8, and the rotation of the arc-shaped clamping block 9 drives the automobile brake drum to rotate and adjust. When the automobile brake drum rotates ninety degrees, the outer surface of the arc-shaped limit block 21 contacts the inner wall of another limit groove 12, and the contact between the two makes the automobile brake drum fixed again. After the assembly is completed, the rotating disk 13 is rotated in the opposite direction. The rotation of the rotating disk 13 drives the arc-shaped clamping block 9 to move in opposite directions through the two-way threaded rod 5, the limit rod 4, the mounting block 6 and the mounting rod 8. The opposite movement of the arc-shaped clamping block 9 makes the automobile brake drum no longer clamped and fixed, and the automobile brake drum can be taken out.
