[0001] The utility model relates to the field of semi-axle processing, in particular to a disc semi-axle processing tool. Background Art

[0002] The half shaft is the shaft that transmits torque between the gearbox reducer and the drive wheel. In the past, most of them were solid, but because the rotational imbalance of hollow shafts is easier to control, hollow shafts are used in many cars.

[0003] A Chinese patent with announcement number CN206794795U discloses a left and right half-axle machining tool for automobiles, including a tool head and a tool body. Tool fixing seats are arranged at the three corners of the tool body, and the tool head is welded inside the tool fixing seat. A limit fixing block is connected to the tool fixing seat through an elastic support rod, and the limit fixing block is located in the middle position inside the tool body. A bolt fixing hole is opened on the elastic support rod, and a fixing groove is sleeved on the outer side of the elastic support rod. A first threaded hole and a second threaded hole are opened in the limit fixing block, and the first threaded hole is located at the center position of the limit fixing block, and the second threaded hole is located outside the first threaded hole.

[0004] The above structure can be used to weld a tool head through a tool fixing seat arranged on the tool body. Later, when the half-shaft needs to be processed, the first threaded hole and the second threaded hole on the tool body can be installed with bolts first, and then the tool body can be installed on the processing machine through the bolts installed in the first threaded hole and the second threaded hole. At this time, the tool head can cut the outer surface of the half-shaft, but the installation method of the above tool head causes it to only process the outer surface of the half-shaft. When a disc is provided on the end of one end of the half-shaft and processing needs to be performed inside the disc, the installation of the above tool head cannot process the inside of the disc. Utility Model Content

[0005] The utility model provides a half-shaft machining tool with a disk to solve the shortcomings of the prior art that only the outer surface of the half-shaft can be machined and when a disk is arranged at one end of the half-shaft, the interior of the disk cannot be machined.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A half-axle machining tool with a disk comprises a turning tool and a tool disk for mounting the turning tool, the turning tool comprises a tool holder and a tool head arranged on the tool holder, a mounting component for mounting the tool head and enabling the tool head to perform cutting machining on the middle part of the disk is arranged between the tool holder and the tool head, the mounting component comprises a mounting block arranged at one end of the tool holder close to the tool head and extending vertically in a direction away from the tool disk, and the tool head is mounted on the mounting block away from the tool holder.

[0008] By adopting the above scheme, a mounting block is set at one end of the tool holder close to the tool head and extends vertically away from the tool disc, so that the tool head can be installed. When the tool head is pressed onto the mounting block, when the tool head processes the inside of the disc on the half shaft, it will be in a vertical state with the disc, and the tool head can then turn the inside of the disc.

[0009] Preferably, the tool disc is provided with a positioning component for pre-positioning the tool when the tool is mounted on the tool holder, and a fixing component for fixing the tool after the pre-positioning of the tool is completed.

[0010] Preferably, the positioning component comprises a positioning groove provided on the cutter disc near the edge of the cutter disc for partial insertion of a tool holder of the turning tool.

[0011] By adopting the above solution, the turning tool can be pre-positioned when it is installed on the turning tool disc by means of the positioning grooves provided on the turning tool disc, thereby reducing the time for adjusting the turning tool before subsequent processing.

[0012] Preferably, the fixing components include fixing blocks respectively arranged on both sides of the positioning groove on the tool disc, receiving grooves respectively arranged at the ends of the two fixing blocks close to each other, and clamping blocks arranged in the receiving grooves and capable of partially extending out of the receiving grooves. A filling component is arranged between the clamping block and the receiving grooves, which fills the gap between the bottom of the receiving groove and the clamping block when the clamping block partially extends out of the receiving groove and causes the clamping block to squeeze the turning tool. Moving components that can drive the clamping block to move toward the turning tool in the positioning groove are also arranged on the two clamping blocks.

[0013] By adopting the above scheme, the clamping block arranged in the accommodating groove can partially extend out of the accommodating groove when the turning tool is inserted into the positioning groove. When the clamping block partially extends out of the accommodating groove, a gap will appear between the clamping block and the bottom of the accommodating groove. At this time, the gap between the clamping block and the bottom of the accommodating groove can be compensated by a filling component, so that the clamping block can maintain a state of partially extending out of the accommodating groove. At the same time, when the filling component is installed into the gap between the clamping block and the bottom of the accommodating groove, the clamping block can also apply pressure to the turning tool in the positioning groove, thereby fixing the turning tool on the tool disc.

[0014] Preferably, the filling component includes a through slot which is arranged on the top or bottom of the fixing block near the bottom of the slot and is interconnected with the slot, and a gasket which can be inserted through the through slot and between the slot and the bottom of the extended pressing block.

[0015] By adopting the above scheme, the gasket can be inserted between the bottom of the accommodating groove and the bottom of the pressing block when the turning tool is installed in the positioning groove and the clamping block in the accommodating groove partially extends out of the accommodating groove, so that the pressing block can remain partially extended out of the accommodating groove. At the same time, the pressing block can also apply pressure to the turning tool in the positioning groove, thereby fixing the turning tool on the tool disc, and the through groove arranged at the top or bottom of the fixing block and interconnected with the accommodating groove allows the gasket to be inserted from the through groove into the accommodating groove.

[0016] Preferably, the moving component comprises a magnet embedded on one end of the pressing block close to the turning tool in the positioning groove.

[0017] By adopting the above scheme, a magnet is arranged on one end of the clamping block close to the turning tool in the positioning groove, so that when the turning tool is inserted into the positioning groove, it can be adsorbed with the surface of the turning tool. At this time, the end of the clamping block away from the bottom of the accommodating groove will partially extend out of the receiving groove, thereby facilitating the worker to insert the filling part between the bottom of the receiving groove and the bottom of the clamping block. At the same time, when the magnet is adsorbed with the turning tool in the positioning groove, the probability of the turning tool falling off the tool disc during the fixing process can also be reduced.

[0018] Preferably, a storage hole for storing the gasket is provided in the middle of the cutter disc, and an opening and closing component for opening and closing the storage hole is provided at the opening of the storage hole.

[0019] By adopting the above scheme, the storage hole set on the tool disc can be used to store the gasket. When the worker needs to install the turning tool, the gasket can be taken out of the storage hole and inserted between the bottom of the receiving groove and the bottom of the turning tool, so that the clamping block remains partially extended out of the receiving groove, and the opening and closing component set can control the opening and closing of the storage hole, reducing the probability of the gasket stored in the storage hole falling out of the storage hole.

[0020] Preferably, the opening and closing component includes a cover plate arranged at the opening of the storage hole and having the same shape and size as the storage hole, an external thread is arranged on the outer wall of the cover plate, and an internal thread that can cooperate with the external thread on the cover plate is arranged on the side wall of the storage hole.

[0021] By adopting the above scheme, the cover plate can be fixedly installed at the opening of the storage hole by matching the external thread set on the outer wall of the cover plate with the internal thread set on the side wall of the storage hole, so that the cover plate closes the storage groove and reduces the probability of the gasket in the storage hole falling out of the storage hole.

[0022] The utility model has a significant technical effect by adopting the above technical solution: a mounting block is arranged at one end of the tool holder close to the tool head and extends vertically in the direction away from the tool disc, so that the tool head can be installed. When the tool head is pressed onto the mounting block, when the tool head processes the inside of the disc on the half shaft, it will be in a vertical state with the disc, and the tool head can then turn the inside of the disc.
