Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing of automobile parts, in particular to a mechanical processing workbench for automobile parts. Background Art

[0002] With the development of science and technology, machining precision parts through machine tools is a common finishing method. Since finishing has strict requirements on the machining accuracy of the workpiece, the clamping direction of the fixture and the temperature control during machining need to be fully considered. The traditional workbench cannot well meet the clamping limit of special-shaped parts. In the actual application of mechanical processing, due to the various processing methods (such as edge grinding, painting, etc.) of special-shaped parts, the position to be fixed and the surface to be displayed are not fixed.

[0003] The patent with announcement number CN115647973B discloses a mechanical processing workbench for automobile parts, including a workbench, a plurality of slide grooves are evenly staggered on the top of the workbench, and a plurality of support columns are slidably connected to the inner cavities of the plurality of slide grooves, a heat dissipation bellows is fixedly installed at the bottom of the workbench, a plurality of inflatable mechanisms are arranged on the top of the heat dissipation bellows, and the inflatable mechanisms are arranged in the clamping holes opened at the axial positions of the staggered points of the plurality of slide grooves, and a connecting mechanism for communicating with the inflatable mechanism is slidably connected to the inner cavity of the support column, a support sleeve is fixedly connected to the top of the support column, a limiting mechanism is rotatably connected to the inner cavity of the support sleeve, an abutment mechanism for limiting the position of the part to be processed is slidably connected to one side of the support sleeve, and the two sides of the limiting mechanism are respectively fitted with the abutment mechanism and the connecting mechanism; by realizing self-communication with the heat dissipation bellows after the abutment mechanism is assembled, it is avoided that the gas purge pressure is reduced due to the multiple groups of air outlet holes arranged in the heat dissipation bellows, and the fixed-point cooling of the abutment position of the contact surface of the special-shaped part is realized, so as to avoid affecting the rapid dissipation of the heat of the part processing.

[0004] Although the above technical scheme can cool down the special-shaped automobile parts, the peripheral side surfaces of the special-shaped parts to be processed can be fitted through multiple abutment fins, and then the special-shaped parts to be processed can be initially limited and fixed by multiple abutment fins. The abutment method requires multiple abutment fins to simultaneously adapt and abut the special-shaped automobile parts, and the limited opening of the slide groove makes the moving position of the abutment mechanism limited. Therefore, it is unknown whether it can adapt to the adaptation and abutment of a variety of special-shaped automobile parts. Therefore, the adaptability of the above technical scheme is still insufficient.

[0078] The buckle rod assembly is inserted into the staggered points of the rod-shaped members of the two bottom frame structures.

[0079] The working principle of the present invention is as follows:

[0080] Loosen the hand wheel 203 to pull out the rope 204, and then select a suitable position according to the shape of the automobile special-shaped part to clamp the positioning clamp mechanism 3 on it. By pulling out ropes 204 of different lengths, the positioning clamp mechanism 3 can be clamped at any part of the automobile special-shaped part as needed, and the sleeve 206 will also rotate according to the direction of pulling the rope 204, so that the tension direction of the rope 204 is correspondingly corrected, thereby providing more connection position options for automobile special-shaped parts, higher freedom of the clamping position, and better adaptability and processing.

[0081] When the positioning clamp mechanism 3 is fully clamped on the special-shaped parts of the automobile, the excess rope 204 is rolled up into the winch inside the shell 201 through the hand wheel 203, so that the rope 204 is tensioned, and through the connection between the wire twisting mechanism 2 and the output end of the electric telescopic rod 102, under the gravity pull of the special-shaped parts of the automobile and the tension of the rope 204, the sleeve 206 moves down along the output end of the electric telescopic rod 102, and the compression spring 207 presses the tooth 208 into the slot 105, forming a buckle for the rotation direction of the wire twisting mechanism 2, thereby improving the linkage automation, simplifying the operation steps, and improving work efficiency.

[0082] By setting the electric telescopic rod 102, the height position of the wire twisting mechanism 2 in different directions can be adjusted, so as to adapt to the shape of special-shaped automobile parts or the adjustment of the processing surface, improve the adjustability, and ensure the quality of the processing work.

[0083] Through the setting of the positioning clamp mechanism 3, the positioning clamp mechanism 3 can clamp a certain part on the automobile special-shaped parts. The clamping space occupied by the positioning clamp mechanism 3 is smaller, which is more suitable for the surface shape of the automobile special-shaped parts. Each positioning clamp mechanism 3 independently clamps the automobile special-shaped parts. The clamping of a single positioning clamp mechanism 3 is controllable, avoiding the problem of extrusion and deformation of automobile special-shaped parts caused by the clamping of multiple components, thereby improving the connection protection of automobile special-shaped parts.

[0084] By clamping the automobile special-shaped parts at different positions through multiple positioning clamp mechanisms 3, the special-shaped parts of the automobile can be protected. At the same time, the winding rope 204 is used to make the positioning clamp mechanisms 3 cooperate with each other to stabilize the special-shaped parts of the automobile through uniform tension.

[0085] By clamping and connecting the automobile special-shaped parts through the positioning clamp mechanism 3 and cooperating with the rope 204 to lift the automobile special-shaped parts in the center of the processing space, the area of ​​the automobile special-shaped parts in contact with the air is increased, the air circulation around the automobile special-shaped parts is better, and the heat dissipation is correspondingly increased.

[0086] After the tensioning rope 204 makes the position of the automobile special-shaped parts stable accordingly, the support rod mechanism 5 is inserted between the adjustment mechanism 6 and the positioning clamp mechanism 3 to further fix the automobile special-shaped parts, and the starter 405 is started to extend the pressure column 404 to abut the receiving ball 313, so that the movable connection between the sleeve 401 and the receiving ball 313 is stuck while ensuring that the universal mechanism 4 is in a vertical state. First, the first column head 502 and the mounting plate 408 are connected, and the staggered points of the rod-shaped part are positioned according to the position of the buckle rod assembly at the lower part of the support rod mechanism 5, so that it is plugged and locked with the buckle rod assembly, and the length of the electric telescopic column 501 is adjusted to support it accurately, and the extension and retraction of the electric telescopic rod 102 can stably perform the corresponding processing of the automobile special-shaped parts, such as positioning and tilting, so as to facilitate the processing of automobile special-shaped parts and help improve their processing efficiency.

[0087] The corresponding buckle rod assembly at the lower part of the support rod mechanism 5 adjusts the bottom frame assembly of the corresponding column assembly in turn, and by loosening the second stop buckle 607 on the rod-shaped part, the adjustment rod 604 slides accordingly along the slide groove 602. When it is positioned to the position corresponding to the buckle rod assembly, the second stop buckle 607 is re-screwed to make it abut against the adjustment frame 601 to complete the positioning of the rod-shaped part. After adjusting the rod-shaped parts of the two bottom frame structures accordingly, the buckle rod assembly and the rod-shaped parts are connected at the staggered points. Through the setting of the adjustment mechanism 6, the rod-shaped parts have a higher degree of adjustment freedom, which can better adjust the special-shaped parts of the automobile, thereby improving adaptability and effective adjustability.
