Description

TECHNICAL FIELD

[0001] The present application relates to the field of numerical control lathes, in particular to a cross head processing device. BACKGROUND

[0002] In the process of processing cross head, the material rod is first processed into the shape by the turning tool, and then the cross slot on the cross head is milled by the milling tool, so that the cross head is formed.

[0003] The inner wall of the cross slot processed by the milling tool which can only move on the XYZ axis coordinate is a straight surface, so that the width of the protrusion between adjacent cross slots is equal along the length direction. If the milling tool can rotate, the milling tool can move on the XYZ and X'Y'Z' axis coordinates, which increases from the original three-axis coordinate to six-axis coordinate. At this time, the milling tool can be obliquely cut into the side wall of the cross head, and then the milling tool is rotated to be obliquely cut from another direction, and the inclination angles of the two tools are opposite. Thus, the inner wall of the cross slot is arc-shaped, and the two inner walls of the cross slot are symmetrically arranged. At this time, the width of the protrusion between adjacent cross slots is greater away from the position of the head of the cross head, which improves the structural strength of the cross head and prolongs the service life.

[0004] The processing device usually includes a clamp for clamping the material rod and rotating, and a processing seat for clamping the turning tool. Two sets of driving assemblies are usually installed below the processing seat for controlling the displacement of the processing seat on the X axis and the Y axis respectively. A lifting assembly is installed on the processing seat for lifting. A lifting rod of the lifting assembly is rotatably connected with a turntable and an angle assembly clamped on the turntable. A rotating motor is fixedly connected to the lifting rod for controlling the rotation of the turntable. A processing motor is fixedly connected to the turntable, and a milling tool is installed on the processing motor. The angle assembly is used to limit the rotation of the turntable. When the turntable is stopped, the angle assembly converts the torsional force of the rotating shaft of the rotating motor into friction force and then transfers it to the angle assembly, which protects the rotating shaft of the rotating motor.

[0005] According to the related technology in the above, the inventors believe that there are the following defects: the angle assembly usually adopts a pneumatic butterfly type brake. When the turntable is subjected to external force, for example, the material rod has high hardness or the milling tool has high feed speed, the brake for fixing the turntable by friction force is easy to slip, which causes the angle of the milling tool to be misaligned. SUMMARY

[0006] In order to improve the problem that the angle assembly is easy to misalign the turntable when encountering external force, the present application provides a cross head processing device.

[0007] The cross head processing device provided by the present application adopts the following technical scheme:

[0012] Optionally, the trigger assembly comprises a trigger block arranged on the angle plate, a trigger groove is formed in the lifting seat, a sliding block slides in the trigger groove, the trigger block drives the sliding block to slide, an insertion block is arranged on the sliding block, an insertion groove for inserting and sliding the insertion block is in communication between the trigger groove and the limiting groove, a locking groove for inserting the insertion block is formed in the limiting block, a first spring is arranged between the locking disc and the locking groove, and the first spring is used for pushing the locking disc to insert the locking rod into the locking hole.

[0013] By adopting the technical scheme, when the angle disc rotates to a certain angle, the trigger block will push the sliding block to slide, and the plug block will slide towards the direction of exiting the locking slot; when the angle disc rotates to a specified angle, the sliding block slides and makes the plug block completely exit from the locking slot, at this time, the locking of the sliding block to the locking disc is unlocked, and the locking disc will be pushed out towards the direction of the angle disc under the elastic force of the first spring, so that the automatic triggering of the locking lever to lock the angle disc is realized, which greatly facilitates the operation.

[0014] Optionally, the trigger slots are at least two, and the two trigger slots are symmetrically distributed on the two sides of the limiting block; a linkage slot is communicated between the two trigger slots; a linkage block is slidably arranged in the linkage slot; the linkage block abuts against the trigger blocks in the two adjacent trigger slots; when one sliding block slides, the linkage block drives the other sliding block to slide, so that the plug block exits from the locking slot to realize unlocking; a second spring is arranged between the inner wall of the linkage slot and the linkage block; the second spring extends and retracts in the direction of pushing the two sliding blocks to reset; a third spring is arranged between the inner wall of the trigger slot and the sliding block; and the third spring extends and retracts in the direction of the sliding block away from the trigger block.

[0015] By adopting the technical scheme, the linkage block is pushed by the sliding block to slide, and then the other sliding block is driven to slide by the sliding of the linkage block, so that the triggering of the two sliding blocks is realized at the same time, the angle disc rotates in two opposite directions, and when the trigger block pushes the different sliding blocks to slide, one sliding block can drive the other sliding block to slide through the linkage block, so that the locking disc can be triggered by the same limiting block when the angle disc rotates in two opposite directions, and the structure is simplified.

[0017] When the plug is inserted in the lock slot and the locking disc is at a position far from the angle disc, the locking rod is not inserted in the locking hole, at this time, the second contact ring presses the first contact ring on the locking ring, so that the fixed block is inserted in the fixed slot, the locking of the first contact ring, the first sleeve ring, the angle disc, the locking ring and the rotating shaft of the rotating driving element is realized, so that the rotating shaft of the rotating driving element drives the angle disc to rotate, when the plug is withdrawn from the lock slot, the locking disc slides close to the angle disc, the locking rod slides and is inserted into the locking hole, the second contact ring releases the contact with the first contact ring, so that the fixed block is withdrawn from the fixed slot, so that the locking of the angle disc and the rotating shaft of the rotating driving element is realized when the locking rod is inserted into the locking hole, so that the angle disc is difficult to drive the rotating shaft of the rotating driving element to rotate when the angle disc is misrotated, and the rotating shaft of the rotating driving element is also difficult to drive the angle disc, the stability of the angle disc when locked is improved; at this time, when the angle disc is subjected to external force, the external force only acts on the locking rod, greatly reducing the axial torsion force of the angle disc on the rotating shaft of the rotating driving element, further protecting the rotating shaft of the rotating driving element.

[0018] Optionally, the first sleeve ring is embedded with an unlocking spring, two ends of the unlocking spring are in contact with the inner wall of the first sleeve ring and the locking ring respectively, and the unlocking spring stretches and contracts in the direction of pulling the fixed block out of the fixed slot.

[0021] By adopting the above technical scheme, when the elastic force of the unlocking spring is weakened and cannot completely withdraw the fixed block from the fixed slot, the second contact ring will contact the third contact ring during the sliding process due to the insufficient sliding distance of the first sleeve ring, so as to drive the first sleeve ring to continue to slide and withdraw the fixed block from the fixed slot, so as to ensure the unlocking of the angle disc and the rotating shaft of the rotating driving element, and improve the working stability.

[0022] Optionally, the angle disc is internally provided with a reset cavity, the locking hole is in communication with the reset cavity, the rotating driving member rotating shaft is inserted into the reset cavity, the rotating driving member is provided with a reset rod located in the reset cavity, the end wall of the locking rod inserted into the reset cavity is provided in an inclined manner, the reset rod is used for abutting against the end of the locking rod to push the locking rod out of the reset cavity, and the reset hole is formed in the inner wall of the locking hole, the reset rod is provided with a reset column located in the reset hole, and the reset column is used for abutting against and pushing the end of the locking rod.
