[0053] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0054] Reference Figures 1-3 A clamp for processing an automobile brake includes an insert 101, a connecting piece 102, a switch group 103, and an abutting piece 104. The insert 101 is configured in a long strip shape and is inserted into a hole of the automobile brake. The outer wall of the insert 101 is tightly attached to the inner wall of the hole of the automobile brake, and the hole of the automobile brake is closed to form a sealed space. The connecting piece 102 is integrally formed at one end of the insert 101. The outer wall of the connecting piece 102 has a thread for screwing the air suction pump to the connecting piece 102.

[0055] The exhaust hole 101a is provided through the insert 101 and the connecting piece 102, the opening at one end of the insert 101 is the air inlet 101b, and the opening at one end of the connecting piece 102 is the air outlet 101c; the switch group 103 is located in the exhaust hole 101a and is used to open or close the exhaust hole 101a; the abutting piece 104 is integrally formed on the insert 101 and is located between the insert 101 and the connecting piece 102, and the abutting piece 104 has an abutting surface 104a at one end close to the insert 101, the abutting surface 104a abuts against the surface of the automobile brake, and a rubber pad can be attached to the abutting surface 104a to increase the airtightness between the abutting surface 104a and the automobile brake.

[0056] First, the insert 101 is inserted into the fixing groove of the automobile brake, then the air pump is started to suck out the air in the fixing groove of the automobile brake to form a vacuum state, so that the automobile brake is pressed by the atmospheric pressure, the surface of the fixing groove of the automobile brake is tightly attached to the abutting surface 104a, and the automobile brake is fixed on the automobile brake machining clamp, then the switch group 103 is used to close the exhaust hole 101a, so that the fixing groove of the automobile brake is always in a vacuum state, the air pump is turned off, the automobile brake is processed, after the automobile brake is processed, the switch group 103 is used to open the exhaust hole 101a, air enters the fixing groove of the automobile brake, the internal and external air pressures are consistent, and the automobile brake is removed.

[0057] By sucking air, the air in the fixing groove of the automobile brake is exhausted to form a vacuum state, and the atmospheric pressure presses the automobile brake on the automobile brake machining clamp, which can effectively avoid damaging the surface of the automobile brake and leaving marks, and improve the precision and appearance of the automobile brake.

[0058] The switch group 103 comprises a sealing member 103a, a sealing surface 103b, an elastic member 103c, and a support member 103d. The sealing member 103a is a spherical steel ball located in the exhaust hole 101a. The sealing surface 103b is located in the exhaust hole 101a and tightly contacts the surface of the sealing member 103a to close the exhaust hole 101a. The elastic member 103c is a spring, and the sealing member 103a is located between the elastic member 103c and the sealing surface 103b. The support member 103d is threadedly connected in the exhaust hole 101a and has a through hole 103e in communication with the exhaust hole 101a. The elastic member 103c is located between the support member 103d and the sealing member 103a, and the elastic member 103c abuts against the support member 103d. The support member 103d is located at one end of the exhaust hole 101a at the air outlet 101c and has a slot 103f penetrating the support member 103d in the direction of the sealing member 103a on the inner wall of the through hole 103e. When the sealing member 103a blocks the through hole 103e, air flow can also be discharged from the through hole 103e and the exhaust hole through the slot 103f.

[0059] When the air suction pump starts to suck air, the sealing member 103a is moved in the direction of the support member 103d by suction force, compressing the elastic member 103c. At this time, the sealing member 103a is separated from the sealing surface 103b, the exhaust hole 101a is opened, and the air in the fixing groove of the automobile brake is also sucked out, and the fixing groove of the automobile brake is in a vacuum state. Then, the air suction pump is turned off, the elastic member 103c pushes the sealing member 103a to move in the direction of the sealing surface 103b to reset, so that the sealing member 103a tightly contacts the sealing surface 103b to close the exhaust hole 101a. At this time, the fixing groove on the automobile brake is always in a vacuum state, and the automobile brake is pressed on the clamp for automobile brake machining by atmospheric pressure.

[0060] The hand opening group 105 is further provided on the abutting member 104 and is used to manually push the sealing member 103a to move in the direction of the support member 103d to open the exhaust hole 101a. The hand opening group 105 comprises a long rod 105a, a connecting sheet 105b, and a spring 105c. The through hole 103e is provided on the abutting member 104 for the long rod 105a to penetrate and insert. The long rod 105a is configured as a long strip-shaped circular rod, and the axis of the long rod 105a is located on the side of the sealing member 103a away from the support member 103d. After the long rod 105a moves in the direction of the sealing member 103a, the long rod 105a can push the sealing member 103a to move in the direction of the support member 103d to open the exhaust hole 101a.

[0061] The connecting piece 105b is disc-shaped, has a diameter larger than that of the long rod 105a, is located on the long rod 105a away from the sealing member 103a, and is located outside the abutting member 104; the two ends of the spring 105c are fixed on the outer wall of the abutting member 104 and the connecting piece 105b respectively, and are used to drive the long rod 105a to move away from the sealing member 103a.

[0062] When the automobile brake is to be removed from the automobile brake machining clamp, the operator pushes the long rod 105a to move towards the sealing member 103a, so that one end of the long rod 105a pushes the sealing member 103a to move towards the supporting member 103d, the sealing member 103a is separated from the sealing surface 103b, the exhaust hole 101a is opened, the air outside the exhaust hole 101a enters the fixing groove on the automobile brake through the exhaust hole 101a, the air pressure in the fixing groove on the automobile brake is consistent with that outside, the pressing and fixing of the automobile brake is cancelled, and then the automobile brake can be removed from the automobile brake machining clamp.

[0063] The above description is only some of the preferred embodiments of the present disclosure and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the application involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or equivalent features without departing from the above inventive concept.
