Description

Technical Field

[0001] The utility model relates to the technical field of automobile luggage rack processing, and more specifically to a processing fixture for a connecting rod of an automobile luggage rack. Background Art

[0002] The car luggage rack is one of the common accessories of cars nowadays. By installing the luggage rack on the top of the vehicle, some large suitcases, bicycles or tents can be conveniently installed and placed on the top of the car. The luggage racks commonly used in cars are usually made of aluminum alloy, and in order to increase the beauty of the surface of the luggage rack connecting rod processing fixture.

[0003] Car luggage rack connecting rod Figure 1 As shown, in order to make the surface of the luggage rack connecting rod beautiful, it is often necessary to polish and grind the surface of the connecting rod. Since the shape and structure of the automobile luggage rack connecting rod are relatively special, the two ends of the automobile luggage rack connecting rod are curved. In order to ensure stable clamping, the processing fixture is usually clamped on the side wall of the automobile luggage rack connecting rod, resulting in the clamping position being unable to be polished and grinded. The clamping position needs to be replaced or polished again by hand-held grinding, resulting in cumbersome processing steps. Utility Model Content

[0004] The utility model aims to provide a processing fixture for a car luggage rack connecting rod, which can fix the car luggage rack connecting rod without interfering with the polishing and grinding operation on the outer side of the car luggage rack connecting rod, and does not require secondary polishing and grinding, thereby improving the processing efficiency.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A processing fixture for a connecting rod of an automobile luggage rack comprises a base, and clamping assemblies are arranged at both ends of one side of the base. The clamping assembly comprises a double-headed double-outlet air cylinder, a mounting rod is fixedly connected between the double-headed double-outlet air cylinder and the base, and an abutment plate is fixedly connected to the end of the piston rod of the double-headed double-outlet air cylinder.

[0007] Furthermore, the abutment plate is an arc-shaped structure.

[0008] Furthermore, a vacuum suction cup is installed on the base, and the vacuum suction cup is located between the two double-headed and double-outlet cylinders.

[0009] Furthermore, a connecting tube is fixedly provided on the other side of the base, and an internal thread is provided on the inner side of the connecting tube.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] When fixing, the double-headed double-outlet cylinder extends to the inner side of the luggage rack connecting rod, and drives the abutment plates on both sides to approach the side walls of the luggage rack connecting rod. The abutment plates abut against the inner side walls of the luggage rack connecting rod, thereby fixing the car luggage rack connecting rod. This does not interfere with the polishing and grinding operation on the outer side of the car luggage rack connecting rod, and eliminates the need for secondary polishing and grinding, thereby improving processing efficiency.

[0015] like Figure 1 and Figure 2 As shown, a processing fixture for a car luggage rack connecting rod includes a base 1, and clamping assemblies are provided at both ends of one side of the base 1. The clamping assembly includes a double-headed double-outlet cylinder 2, and a mounting rod 3 is fixedly connected between the double-headed double-outlet cylinder 2 and the base 1, and the piston rod end of the double-headed double-outlet cylinder 2 is fixedly connected to an abutment plate 4.

[0016] The abutting plate 4 is in an arc-shaped structure.

[0017] A vacuum suction cup 5 is installed on the base 1 , and the vacuum suction cup 5 is located between the two double-headed and double-outlet cylinders 2 .

[0018] A connecting tube 6 is fixedly provided on the other side of the base 1, and an internal thread is provided on the inner side of the connecting tube 6; by providing the connecting tube 6, it is convenient to install the base 1 on the mechanical wall, so that the car luggage rack connecting rod can be controlled by the mechanical arm to perform polishing and grinding.

[0019] Working principle:

[0020] When fixing, first vacuum adsorb the middle inner side of the connecting rod of the automobile luggage rack through the vacuum suction cup 5, and then the double-headed double-outlet air cylinder 2 extends to the inner side of the connecting rod of the luggage rack, and the double-headed double-outlet air cylinder 2 drives the abutment plates 4 on both sides to approach the side walls of the connecting rod of the luggage rack, and the abutment plates 4 abut on the inner side walls of the connecting rod of the luggage rack, thereby fixing the connecting rod of the automobile luggage rack, without interfering with the polishing and grinding operation of the outer side of the connecting rod of the automobile luggage rack, and without the need for secondary polishing and grinding, thereby improving the processing efficiency.

[0021] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
