Description

Technical Field

[0001] The utility model relates to the technical field of fixed processing on numerically controlled cutting machine tools, in particular to a horizontal clamping fixture for round bar processing numerically controlled lathes. Background Art

[0002] In the field of mechanical parts, round rods are widely used. However, due to the special planar structure of round rods, which require milling of cylindrical surfaces after turning the end faces, multiple steps are required in actual processing. If they are not fixed with matching external fixtures before processing, the processing accuracy will deviate greatly and the milling position will be incorrect.

[0003] In addition, the existing flat structure processing of round rod parts requires the round rods to be clamped on equipment such as machining centers or vertical milling machines for processing. However, such equipment is either expensive, has high operating requirements, or has low processing efficiency, which will increase the production cost of the parts. Therefore, the selection of processing equipment is also greatly limited, affecting the equipment threshold range of enterprise processing. Utility Model Content

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 2 The utility model provides a horizontal clamping fixture for a CNC lathe for processing round bars, which is connected to a hydraulic rotary chuck 4 on a machine tool. A groove is provided on the hydraulic rotary chuck. The horizontal clamping fixture for a CNC lathe for processing round bars includes a fixed seat 2 and a pressing head 3. The fixed seat and the pressing head are respectively arranged on opposite sides of the groove wall. The fixed seat and the pressing head cooperate up and down to clamp the workpiece 1.

[0020] In one embodiment, the hydraulic rotary chuck includes a chuck body and a connecting seat provided at one end of the chuck body, and the groove is provided on an end surface of the chuck body away from the connecting seat.

[0021] It can be understood that the hydraulic rotary chuck is a clamping and fixing base matched with the machine tool, which can rotate with the rotation of the machine tool spindle. The horizontal clamping fixture of the round bar processing CNC lathe is fixed on

[0022] On the hydraulic rotary chuck, the clamp is used to fix the workpiece, and the hydraulic rotary chuck can control the opening, closing, rotation and other actions of the clamp.

[0023] In one embodiment, the space between the fixing seat and the pressing head is a clamping cavity.

[0024] In one embodiment, the surface of the fixing base in contact with the workpiece and / or the surface of the pressing head in contact with the workpiece are arc-shaped, V-shaped, or U-shaped. It is understood that in other embodiments, the shape of the surface of the fixing base in contact with the workpiece and / or the surface of the pressing head in contact with the workpiece is not limited, as long as they can easily fit the workpiece.

[0025] In one embodiment, through holes are formed on two opposite sides of the chuck body, and the fixing seat and the pressure head are fixed to the hydraulic rotary chuck via the two through holes respectively.

[0026] In one embodiment, the fixing seat and the pressing head are both detachably connected to the chuck body. It is understood that the detachable connection methods include, but are not limited to, snap-fitting, plug-in connection, and threaded connection. Specifically, the fixing seat or pressing head can be designed with a structure that matches the corresponding slot of the chuck body to be inserted into the chuck body and locked, as long as it can maintain a secure fixation.

[0027] The connection / assembly relationship of the horizontal clamping fixture for round bar processing CNC lathe of the utility model:

[0028] First, the hydraulic rotary chuck is installed on the machine tool and can be rotated or fixed (when fixed, it can be positioned according to angle);

[0029] Secondly, the fixing seat 2 is installed on one side of the hydraulic rotary chuck;

[0030] Again, the pressure head 3 is installed on the other side of the hydraulic rotary chuck, opposite to the fixed seat;

[0031] Finally, the workpiece is placed on the fixed seat 2, the chuck is started, and the pressing head 3 presses down to fix the workpiece.

[0032] Understandably, existing machine tools, when processing round rod parts with flat structures, require machining each end of the rod separately, then replacing the machine or fixture to re-clamp, and then machining the flat structure or drilling the hole. This requires multiple steps to complete all the machining operations, resulting in cumbersome processing steps, reduced processing efficiency, and increased production costs. However, the fixture structure of the present utility model, combined with the rotary chuck, can complete multiple processes such as end turning, milling, and drilling in a single operation.

[0033] The working principle of the horizontal clamping fixture for round bar processing CNC lathe of this utility model is as follows:

[0034] Based on the shape of the round bar, the fixture is also designed into a matching V-shaped or arc-shaped shape, and it is installed on the fixed seat on the hydraulic rotary chuck on the machine tool to accurately fix the round bar blank.

[0035] After installation, the hydraulic chuck is activated, the pressure head clamps against the workpiece, and one end of the round bar is passed through the rotary mount to align it with the spindle. The machine is then started, the chuck rotated, and the tool moves along the programmed path to complete the end turning. The machine rotates the hydraulic rotary chuck 180° to further machine the other end of the workpiece. To machine the flat surface of a cylindrical segment, the rotary chuck is fixed at an angle, and the side to be machined is rotated perpendicular to the spindle. The machine's secondary spindle is then activated, causing the tool to rotate, and the workpiece is flattened along the programmed path.

[0036] The working mode of the horizontal clamping fixture for round bar processing CNC lathe of the utility model is the same as the working principle. The machine tool is set to rotate the hydraulic rotary chuck 90°-180° and other angles to further process the other side of the part.

[0037] The utility model of the horizontal clamping fixture for round bar processing CNC lathe reduces the number of round bar milling processing steps, lowers the threshold of processing equipment, saves processing costs, and can process with high efficiency. The utility model of the horizontal clamping fixture for round bar processing CNC lathe, firstly, through the automatic reversing, reduces the number of workpiece clamping times, shortens the auxiliary installation time, and reduces the time cost; secondly, the processing operation is convenient and quick, and manual installation is no longer required multiple times, which reduces labor costs; thirdly, the relative position of each processing surface of the workpiece is fully guaranteed, avoiding large dimensional errors; finally, the processing accuracy is improved, the production quality is guaranteed, and the production cost is reduced.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
