Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a positioning fixture suitable for processing columnar aluminum parts. Background Art

[0002] Aluminum is a silvery-white light metal, and its content in the earth's crust ranks third after oxygen and silicon. Aluminum has a low density and good ductility, thermal conductivity, and electrical conductivity. It is widely used in modern industrial production and life. It is the non-ferrous metal with the second largest output and usage in the world after steel. A fixture is a device used to fix the object to be processed in the mechanical manufacturing process, so that it is fixed in the correct position to be processed or tested, and is also called a fixture.

[0003] At present, when the positioning fixture used for processing columnar aluminum parts is in use, due to the columnar nature of the aluminum parts, it is necessary to manually hold the aluminum parts with hands when adding and placing the aluminum parts. The clamp can only be released after the clamp completes clamping and fixing. The use is relatively cumbersome, and when the clamp is in use, the driving component of the clamping structure will also block the aluminum parts, which is inconvenient for subsequent processing of the aluminum parts.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0022] A positioning fixture suitable for processing columnar aluminum parts, comprising a base 1, two ends of the top of the base 1 are provided with slide grooves 2, one end of the inside of the slide groove 2 is movably provided with a slider 3, a clamping block 4 is fixedly provided on the top of the slider 3, a pre-support mechanism is provided between the clamping blocks 4 on the top of the base 1, a bracket 5 is fixedly provided on one side of the top of the base 1, a first connecting rod 6 is fixedly provided on one side of the top of the clamping block 4, and a driving mechanism is provided between the bracket 5 and the end of the first connecting rod 6 away from the clamping block 4;

[0023] Through the above scheme, the clamping work of the columnar aluminum part is completed by the clamp block 4, thereby realizing the clamping function of the clamp;

[0024] In this embodiment, preferably, the pre-support mechanism includes a strip groove 7, a bidirectional screw rod 8, a moving block 9 and an arc-shaped support block 10. A strip groove 7 is opened between the slide grooves 2 at the top of the base 1. A bidirectional screw rod 8 is movably arranged inside the strip groove 7 through a rotating shaft. The outer sides of both ends of the bidirectional screw rod 8 are movably arranged with moving blocks 9 through threads. An arc-shaped support block 10 is fixedly arranged on the top of the moving block 9.

[0025] Through the above scheme, the use of the pre-support mechanism can make it possible to pre-support the aluminum part when placing the columnar aluminum part, and there is no need to manually hold the aluminum part to assist in the use of the clamp, which facilitates the specific use of the clamp, and the arc-shaped support block 10 can be used flexibly. Before the subsequent aluminum part processing, it can be removed so that the aluminum part can be suspended in the air after being clamped and fixed, thereby facilitating the subsequent aluminum part processing;

[0026] In this embodiment, preferably, the driving mechanism includes a rotating rod 11 and a second connecting rod 12. The rotating rod 11 is movably provided at the bottom of one side of the top of the bracket 5 through a rotating shaft. The second connecting rod 12 is movably provided at both ends of the rotating rod 11 through a rotating shaft. The end of the second connecting rod 12 away from the rotating rod 11 is movably connected to the first connecting rod 6 through a rotating shaft.

[0027] Through the above solution, the two clamping blocks 4 are driven to move closer to each other by using the driving mechanism to achieve the clamping function;

[0028] In this embodiment, preferably, a motor 13 is installed on the top of the bracket 5 through a mounting seat, and the output shaft end of the motor 13 is transmission-connected to the rotating shaft where the rotating rod 11 is located through a coupling;

[0029] Through the above solution, the rotating rod 11 can be driven to rotate by the driving mode of the motor 13;

[0030] In this embodiment, preferably, the arc surface of the arc support block 10 is provided with a rubber pad 15;

[0031] Through the above solution, the rubber pad 15 is used to improve the anti-slip performance of the supporting surface of the arc-shaped supporting block 10, and can also prevent the surface of the columnar aluminum part from being worn due to hard contact;

[0032] In this embodiment, preferably, both sides of the moving block 9 are provided with through grooves 16, and rollers 17 are movably arranged inside the through grooves 16;
