[0002] In related technologies, a wheel machining lathe is disclosed. Referring to Figure 1 , this lathe includes a bed 100, a headstock 110, a tool rest 120, a first driving component 130, and a second driving component 140; the headstock 110 is installed at both ends of the bed 100, and the two headstocks 110 slide towards or away from each other for clamping a wheel 150; the tool rest 120 is slidably connected to the side wall of the bed 100, and a turning tool 121 is installed on the tool rest 120 for machining the wheel 150; the first driving component 130 is installed at both ends of the bed 100 for driving the movement of the corresponding headstock 110, and the second driving component 140 is installed on the side wall of the bed 100 for driving the movement of the tool rest 120. Both the first driving component 130 and the second driving component 140 are lead screw drive structures.
[0003] Since there is a certain inertia when the headstock 110 slides, even after the first driving component 130 stops, the headstock 110 will still apply a thrust force in the sliding direction to the wheel 150 under the influence of inertia, which is likely to affect the wheel 150. Seriously, it will affect the machining accuracy and machining stability of the wheel 150. Utility Model Content
[0004] In order to improve the machining accuracy and machining stability of wheels, this application provides a wheel lathe that can improve the machining accuracy of wheels, and adopts the following technical solutions:
[0005] A wheel lathe that can improve the machining accuracy of wheels includes
[0006] A bed:
[0007] A headstock, slidably connected to the bed;
[0008] A sliding component for driving the sliding of the headstock;
[0009] A wire rope encoder, installed on the bed, with a wire rope connected to the headstock, for collecting the travel of the headstock movement;

If the sliding stroke reaches the preset deceleration stroke, the controller will control the guide rail clamp to act, so that the headstock starts to decelerate, thereby being able to brake the headstock in time, and thus being able to improve the machining accuracy and machining stability of the wheel.
[0014] Optionally, the sliding member includes:
[0015] A sliding motor, which is installed on the bed body and is communicatively connected to the controller;

[0020] A torque limiting coupling, one end of which is coaxially connected to one end of the sliding lead screw, and the other end of which is coaxially connected to the output shaft of the sliding motor.
[0021] By adopting the above technical solution, after the headstock is braked, even if the output shaft of the sliding motor rotates under the action of inertia, under the action of the torque limiting coupling, when the torque applied by the sliding motor is too large, the output shaft of the sliding motor will not drive the rotation of the sliding lead screw, thereby further improving the machining accuracy and machining stability of the wheel.
[0022] Optionally, the wheel lathe further includes:
[0023] A baffle, which is installed on the side walls on both sides of the headstock and abuts against the bed body;
[0024] A protective cover, which covers the bed body, is telescopically arranged, and one end of which is connected to the bed body and the other end of which is connected to the headstock.
[0025] By adopting the above technical solution, the protective cover covers the sliding lead screw and plays a protective role for the sliding lead screw; the setting of the baffle plays a protective role for the guide rail clamp.
[0026] Optionally, both the protective cover and the baffle are mounted on the headstock by bolts.
[0027] By adopting the above technical solution, it is convenient to disassemble the protective cover and the baffle.
[0028] Optionally, the wheel lathe further includes:
[0029] A connecting block, fixedly connected to the sliding seat; the headstock is provided with a mounting groove, and the connecting block can be clamped in the mounting groove; the headstock is mounted on the guide rail clamp by bolts;
[0030] A locking member for locking the connecting block and the headstock.
[0031] By adopting the above technical solution, it is convenient to disassemble the headstock.
[0032] Optionally, the locking member includes:
[0033] A locking nut, fixedly connected to the headstock;

[0035] A locking block, rotatably connected to one end of the locking bolt; a locking groove is provided on the side wall of the connecting block, and the locking block can be clamped in the locking groove.
[0036] By adopting the above technical solution, after the connecting block is clamped in the connecting groove, the locking bolt is rotated, so that the locking block is clamped in the locking groove, so as to realize the locking of the connecting block and the headstock, so that when the sliding seat moves, the headstock is driven to slide; thus, after the protective cover is disassembled, it is convenient to disassemble the headstock.
[0037] Optionally, the wheel lathe further includes:
[0038] A promptor, mounted on the bed body and communicatively connected to the controller.
[0039] By adopting the above technical solution, when the headstock is braked, the controller can control the promptor to give a prompt.
[0040] In summary, the present application has at least the following beneficial effects:
[0041] 1. The purpose of setting the wire-drawing encoder, the guide rail clamp and the controller is that when the sliding component drives the headstock to move, the wire-drawing encoder will collect the sliding stroke of the headstock, and the controller will judge the sliding stroke. If the sliding stroke reaches the preset deceleration stroke, the controller will control the guide rail clamp to act, so that the headstock starts to decelerate, so as to be able to brake the headstock in time, thereby improving the machining accuracy and machining stability of the wheel.
[0042] 2. The purpose of setting the torque-limiting coupling is that after the headstock is braked, even if the output shaft of the slip motor rotates under the action of inertia, under the action of the torque-limiting coupling, when the torque applied by the slip motor is too large, the output shaft of the slip motor will not drive the rotation of the slip lead screw, thereby further improving the machining accuracy and machining stability of the wheel.
[0043] 3. The purpose of setting the protective cover of the baffle is to protect the slip lead screw and the guide rail clamp. Brief Description of the Drawings

[0052] Taking a set of sliding members 200 as an example, the sliding member 200 may include a sliding motor 201, a sliding lead screw 202, and a sliding seat 203.

The output shaft of the sliding motor 201 is installed through a speed reducer and the torque limiting coupling 204.
[0053] In order to realize the sliding connection between the headstock 110 and the bed 100, taking the headstock 110 at one end of the bed 100 as an example: a guide rail 210 is installed at this end of the bed 100 by bolts, a guide rail clamp 220 is slidably connected to the guide rail 210, and the headstock 110 is installed on the guide rail clamp 220 by bolts.

Locking grooves are opened on both side walls of the connecting block 205, and the locking block 233 can be clamped in the corresponding locking grooves.
[0056] Refer to Figure 4, as another embodiment of the wheel lathe, the wheel lathe may include a baffle 240 and a protective cover 250.
