Abstract
The invention discloses a grinding and processing method of the circumference of an automobile drum type brake grinding and correcting concentric circle. The method is characterized in that the method comprises the steps of (1) installing a brake drum and a brake pad; (2) starting a tooling fixture, and driving the brake drum to run by the tooling fixture; (3) feeding grinding raw material into the brake drum when the brake drum runs; (4) carrying out primary grinding; (5) removing the fed grinding raw material; (6) installing the brake drum again, then filling river sand, and grinding; (7) taking down the brake drum and the brake pad, and cleaning. The processing method has the advantages that 1, the contact surface between the brake drum and the brake pad is close to 100%; 2, when an automobile runs, the energy consumption is reduced; 3, the brake effect is good, and the effects of being safe and reliable can be achieved; 4, the brake forces and time of four wheels of the automobile are consistent.
Description
Technical field
The present invention relates to a kind of restorative procedure of automotive drum type braking device, is specifically the grinding method that a kind of automotive drum type braking grinds check and correction concentric circle.
Background technology
As everyone knows, an indispensable part in brake gear formula automobile; Automobile is frequent apply the brakes device in driving process.Brake shoe is the thing of half arc in drum brake, generally be cast as, friction plate is exactly that brake block is riveted on brake shoe, forms a whole, but many times also often this entirety being made up of brake shoe and brake block is called to brake shoe or brake block in word.Brake shoe is fixed on transfixion on back-plate.Brake shoe is the consumptive material of manufacturing pressure and frictional force to brake disc/drum, and brake block is also like this.But brake rim, is also brake drum, it is the thing of brake shoe friction.
There is following shortcoming in existing mode: existing mode adopts brake rim and the processing of brake block separate type, i.e. brake rim and brake block machine-shaping on lathe separately, loads onto operation by brake rim and brake block subsequently; Under normal circumstances, should be in concentric structure between satisfactory brake rim and brake block, the arc outer of brake block should be with the interior edge of brake rim in concentric circles.But separate type processing can make between brake rim and brake block unavoidably cannot be in described concentric circles state, thus exist do not mate, the factor such as deviation is large, weak effect, therefore can cause braking efficiency low.
In the course of time, cause brake gear wearing and tearing, then cause brake failure, and pernicious traffic accident occurs.The malfunctioning wearing and tearing of brake gear, be mainly brake brake rim and the brake block of brake between wearing and tearing and cause it malfunctioning.Cause the wearing and tearing between automobile brake drum and brake block, and the concentric circles not forming between the brake rim before wearing and tearing and brake block is destroyed, thereby occur brake " biting " and machinery " electric shock ' ' phenomenon occurs then to cause parts damage, damage or malfunctioning, even causes traffic accident generation.
Summary of the invention
The object of the invention is to provides a kind of automotive drum type braking to grind the grinding method of check and correction concentric circle at this; Can overcome the shortcoming that separate type machining produces; Automotive drum type braking is carried out to two-in-one grinding; Possess following advantage: the contact-making surface of brake rim and brake block approaches 100%, braking effect is good, safe and reliable.
The present invention is achieved in that a kind of automotive drum type braking of structure grinds the grinding method of check and correction concentric circle, is characterized in that: operation in the following manner;
(1), brake rim and brake block are installed on frock clamp simultaneously, and through debugging, to make the gap length between its brake rim and brake block be 40-60 silk in debugging, and its object is to make the gap between brake rim and brake block to be less than the gap between brake rim and brake block in automobilism;
(2), start frock clamp; Make it drive brake rim running;
(3), brake rim in operation process, in brake rim, add grinding raw material by funnel, for grind; The mixing of grinding raw material employing diamond dust and river sand, mixed proportion is diamond dust 70%: river sand 30%; Diamond dust is realized the grinding reparation of brake rim and brake block, plays polishing brake rim, brake block, makes it reach the object with concentric circumferences;
(4), tentatively grind: according to clockwise grinding 5 minutes, grind counterclockwise and grind for 5 minutes;
(5), take off brake rim, and remove added grinding raw material;
(6), again load onto brake rim, reinstall afterwards river sand, adjust the gap 20-30 silk between brake rim and brake block, then to grind clockwise 5 minutes, grind counterclockwise the mode of 5 minutes and grind;
(7), take off brake rim and close brake block, clean up.
The invention has the advantages that: processing method of the present invention, automotive drum type braking is ground to the grinding method of proofreading concentric circle; Possess following advantage:
1, the contact-making surface of brake rim and brake block approaches 100%,
2, automobile is in operation and has reduced the loss of the energy;
3, braking effect is good, safe and reliable;
4, the four-wheel braking strength of car is consistent, time consistency;
5, the brake rim of processing by this method is difficult for breakking away in practice.
Brief description of the drawings
Fig. 1 is that brake rim and brake block are installed to frock clamp schematic diagram simultaneously
Wherein: 1, brake rim, 2, brake block, 3, raw material adds entrance.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the present invention is described in detail, and the technical scheme in the embodiment of the present invention is clearly and completely described, and obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The grinding method that the present invention provides a kind of automotive drum type braking to grind check and correction concentric circle at this, in the following manner operation;
(1), as shown in the figure, brake rim and brake block are installed on frock clamp simultaneously, and through debugging, to make the gap length between its brake rim and brake block be 40-60 silk in debugging, and its object is to make the gap between brake rim and brake block to be less than the gap between brake rim and brake block in automobilism.
(2), start frock clamp; Make it drive brake rim running.
(3), brake rim in operation process, in brake rim, add grinding raw material by funnel, for grind; The mixing of grinding raw material employing diamond dust and river sand, mixed proportion is diamond dust 70%: river sand 30%; Diamond dust is realized the grinding reparation of brake rim and brake block, plays polishing brake rim, brake block, makes it reach the object with concentric circumferences.
(4), tentatively grind: according to clockwise grinding 5 minutes, grind counterclockwise and grind for 5 minutes.
(5), take off brake rim, and remove added grinding raw material.
(6), again load onto brake rim, reinstall afterwards river sand, adjust the gap 20-30 silk between brake rim and brake block, then to grind clockwise 5 minutes, grind counterclockwise the mode of 5 minutes and grind.
