Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a workpiece turning device for machining. Background Technology

[0002] Lathe machining is an important part of mechanical processing, mainly using a cutting tool to cut rotating workpieces to obtain the required shape and size. During lathe machining, some parts need to be machined on both sides, requiring them to be flipped during the process. Traditional manual flipping is time-consuming and labor-intensive, so corresponding equipment is now being used to replace manual flipping of parts, effectively improving machining efficiency.

[0003] For example, Chinese patent CN112427661A provides a CNC lathe workpiece flipping mechanism. The workpiece is clamped by a clamping plate and the clamping plate is driven to rotate by a drive motor to flip the workpiece. It can automatically flip the workpiece, which solves the problem that most existing flipping methods rely on manual flipping by workers. This method has low work efficiency, increases the labor intensity of workers, and is prone to safety accidents when the workpiece is heavy.

[0004] However, when using existing lathe machining part flipping devices, if the workpiece is short, it can only clamp and flip the end of the workpiece. This results in the other end of the workpiece being blocked by the clamping device and unable to be clamped by the lathe chuck, thus reducing the applicability of the existing flipping devices. Therefore, a workpiece machining flipping device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a workpiece turning device for lathe machining, which solves the technical problem mentioned in the background art: when using existing lathe turning devices for machining parts, if the length of the workpiece is small, only one end can be clamped and then turned, resulting in the other end of the workpiece being blocked by the clamping device and unable to be clamped by the lathe chuck.

[0013] A first cylinder is arranged in the fixed frame; and

[0014] A mounting disc is fixedly arranged on the output shaft of the first cylinder, and the pushing disc is detachably arranged on the side of the mounting disc facing the clamping jaw.

[0015] In a preferred embodiment, a flexible pad is arranged on the outer side of the clamping jaw, and the flexible pad is fixedly arranged on the inner side of the clamping shell.

[0016] In a preferred embodiment, the driving mechanism comprises:

[0017] A second cylinder is fixedly arranged in the mounting cylinder, and a pushing plate is arranged on the output shaft of the second cylinder;

[0018] A movable plate is slidably arranged in the mounting cylinder along the axis of the mounting cylinder and arranged on one side of the pushing plate, and two sets of hinged seats are arranged on the movable plate; and

[0019] Two sets of connecting rods are arranged, one end of each connecting rod is hingedly connected to the hinged seat, and the other end of each connecting rod is hingedly connected to the clamping shell.

[0020] In a preferred embodiment, an elastic member is arranged between the movable plate and the pushing plate.

[0021] In a preferred embodiment, a limiting column is arranged on one side of the pushing plate, the limiting column penetrates the movable plate, and a limiting block is arranged on the end of the limiting column.

[0032] The utility model is further described in detail below with reference to the drawings. It is necessary to point out that the following specific embodiments are only used for further illustrating the utility model and cannot be understood as limiting the protection scope of the utility model. Those skilled in the art can make some non-essential improvements and adjustments to the utility model according to the above application content.

[0033] Embodiment:

[0034] As shown in Figure 1 , 2 The utility model provides a workpiece turning over device, including the base 101 of the moving platform of lathe, the rudder 201 of fixed setting of base 101, the output shaft of rudder 201 is provided with the installation cylinder 202, the end of installation cylinder 202 is provided with the mounting seat 203, and the two groups of clamping shell 204 of opposite arrangement are hinged to mounting seat 203, and the clamping claw 206 is arranged in clamping shell 204, and the drive mechanism of driving two groups of clamping shell 204 opening and closing is arranged in installation cylinder 202.

[0035] The drive mechanism includes the second cylinder 301 fixedly arranged in the installation cylinder 202, the output shaft of second cylinder 301 is provided with the propulsion plate 302, the movable plate 305 is slidably arranged in the installation cylinder 202 along its axis, the movable plate 305 is arranged on one side of the propulsion plate 302, the movable plate 305 is provided with two groups of hinged seats 306, and the drive mechanism further includes two groups of connecting rods 307, one end of the connecting rod 307 is hinged to the hinged seat 306, and the other end is hinged to the clamping shell 204.

[0036] When the device is used, the base 101 can be controlled to move horizontally and longitudinally on the machine tool through the moving platform of the machine tool, when the end of the workpiece is finished, it can be moved to the machining area, and the two groups of clamping shells 204 are moved to the upper and lower sides of the workpiece, then the second cylinder 301 is controlled to elongate, the second cylinder 301 drives the propulsion plate 302 to move in the installation cylinder 202, the movable plate 305 is pushed to move through the propulsion plate 302, and the two groups of clamping shells 204 are pushed to close through the connecting rod 307 in the movement process of the movable plate 305, so that the end of the workpiece protruding from the chuck is clamped through the clamping claw 206, then the chuck is controlled to loosen, and then the rudder 201 is started to make the installation cylinder 202 overturn as a whole, so that the workpiece can be turned over.

[0037] As shown in Figure 1As shown, in this embodiment, a pusher plate 105 connected by a pushing mechanism is provided on the base 101.

The pusher plate 105 is detachably mounted on the side of the mounting plate 104 facing the grippers 206.

[0038] When the length of the workpiece is small or the size of its protrusion on one side of the chuck is small, the jaw 206 can only clamp the end of the workpiece. After being flipped, the workpiece is blocked by the jaw 206 and cannot be directly clamped by the chuck. At this time, the first cylinder 103 can be started to drive the mounting plate 104 to move horizontally, so that the other end of the workpiece can be pushed by the push plate 105 to slide within the jaw 206 until the end of the workpiece close to the chuck extends out of the jaw 206.

A limiting post 303 is provided on one side of the push plate 302, penetrating the movable plate 305, and a limiting block 304 is provided at its end. The elastic element 308 also allows the two sets of grippers 206 to be in a flexible clamping state, avoiding damage to the workpiece during pushing caused by traditional rigid clamping. After retracting the second cylinder 301, the movable plate 305 can be pulled back to its original position under the action of the limiting post 303, thus releasing the workpiece.

[0040] The specific usage and beneficial effects of this utility model are as follows:
