Description

Technical Field

[0001] The utility model relates to a loading and unloading device for a numerically controlled lathe, belonging to the technical field of numerically controlled lathes. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, reaming and boring, etc. CNC machine tools automatically process the parts according to the pre-compiled processing program. We compile the processing route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool, thereby commanding the machine tool to process parts.

[0003] When CNC lathes are grooving, drilling, reaming, boring and other operations on parts, they will generate a lot of downward pressure on the parts. After the parts are processed, the parts may be stuck in the fixed position where the parts are placed during processing due to the downward pressure during processing, so that the operator needs to spend more effort to load and unload the parts, which is inconvenient for the operator to use.

[0004] Therefore, a loading and unloading device for a numerically controlled lathe is proposed. Utility Model Content

[0005] In view of this, the utility model provides a loading and unloading device for a CNC lathe to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model is implemented as follows: a loading and unloading device for a CNC lathe comprises a lathe box, vertical rods are fixedly installed on the left and right sides and the front side of the top of the lathe box, top plates are fixedly installed on the tops of the three vertical rods, a cylinder is fixedly installed on the top of the top plate, a processing device is fixedly installed on the bottom of the cylinder, a placing frame is fixedly installed on the top of the lathe box, and unloading mechanisms are arranged around the inner cavity of the lathe box, the unloading mechanism comprises a sliding rod, a sliding block, a hard spring, a movable rod, a mounting plate, a push rod and a push plate, and the four sliding rods are fixedly installed on the outside of the inner cavity of the lathe box.

[0008] Further preferably, a displacement groove is opened on the top of the lathe box, and the push rod passes through the inner cavity of the displacement groove and extends into the inner cavity of the placement frame.

[0009] Further preferably, sliding grooves are provided around the bottom of the inner cavity of the lathe box, and the bottoms of the four sliding blocks are slidably connected in the inner cavities of the four sliding grooves.

[0010] Further preferably, a fixing mechanism is provided at the top of the inner cavity of the lathe box, and the fixing mechanism includes a motor, and the motor is fixedly installed on the top of the inner cavity of the lathe box, and the output end of the motor is fixedly connected to a gear, and an outer gear ring is provided on the top of the lathe box, and the front side of the outer gear ring is meshed with the rear side of the gear, and the top of the outer gear ring is movably connected with a first connecting plate all around, the tops of the four first connecting plates are movably connected with a second connecting plate, and the bottoms of the four second connecting plates are movably connected with mounting blocks, and clamps are fixedly installed on the outer sides of the four mounting blocks.

[0011] Further preferably, limiting grooves are provided around the top of the lathe box, and the bottoms of the four mounting blocks are slidably connected to the inner cavities of the four limiting grooves.

[0012] Further preferably, a moving groove is opened on the top of the lathe box, and moving blocks are fixedly installed around the bottom of the outer gear ring, and the four moving blocks are slidably connected in the inner cavity of the moving groove.

[0013] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0014] 1. The utility model sets an unloading mechanism. When the parts are subjected to downward pressure during processing by the processing device, the parts will move into the inner cavity of the placement frame. At this time, the slider will move outward through the cooperation of the push plate, the push rod and the movable rod, and the hard spring will be deformed under the force. When the processing is completed and the processing device is removed from the surface of the part, the downward pressure disappears. At this time, the hard spring will be deformed again and will push the slider to move inward through its own tension, and the movable rod will flip outward. The push rod will push the parts upward from the inner cavity of the placement frame, thereby completing the work of automatically unloading the parts after processing, avoiding the parts from being stuck in the placement frame and unable to be removed, which affects the operator's processing of subsequent parts.

[0015] Second, the utility model can convert the downward pressure on the parts during processing into an outward thrust by setting a movable rod. When the processing is completed, the hard spring can drive the equipment to unload the parts after processing through its own tension, so that the parts can be moved out of the inner cavity of the placement frame. By setting the displacement groove, the push rod can be limited when it moves, so as to avoid the push rod from deviating when it moves, thereby affecting the automatic unloading of the parts. By setting the sliding groove, the moving direction of the slider can be limited to avoid changing its moving direction, thereby affecting the unloading of the parts after processing. By setting the fixing mechanism, the parts during processing can be fixed to avoid shaking of the parts during processing, resulting in deviation of the processing position and affecting the subsequent use of the parts. By setting the limiting groove, the mounting block can be limited to avoid deviation when the mounting block moves, thereby affecting the clamping of the parts. By setting the moving block and the moving groove, the outer gear ring can be supported while facilitating the position of the outer gear ring to not deviate during rotation, thereby failing to drive the fixture to clamp the parts.

DETAILED DESCRIPTION

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides a loading and unloading device for a CNC lathe, including a lathe box 1, vertical rods 4 are fixedly installed on the left and right sides and the front side of the top of the lathe box 1, a top plate 5 is fixedly installed on the top of the three vertical rods 4, a cylinder 6 is fixedly installed on the top of the top plate 5, a processing device 7 is fixedly installed on the bottom of the cylinder 6, a placement frame 8 is fixedly installed on the top of the lathe box 1, and unloading mechanisms 2 are arranged around the inner cavity of the lathe box 1, the unloading mechanism 2 includes a slide bar 201, a slider 202, a hard spring 203, a movable rod 204, a mounting plate 205, a push rod 206 and a push plate 207, and the four slide bars 201 are fixedly installed on the outside of the inner cavity of the lathe box 1.

[0027] By setting up the unloading mechanism 2, when the parts are subjected to the downward pressure during processing by the processing device 7, the parts will move to the inner cavity of the placement frame 8. At this time, through the cooperation of the push plate 207, the push rod 206 and the movable rod 204, the slider 202 will move outward, and the hard spring 203 will be deformed due to the force. When the processing is completed and the processing device 7 is removed from the surface of the part, the downward pressure disappears. At this time, the hard spring 203 will deform again and push the slider 202 to move inward through its own tension, and make the movable rod 204 flip outward. The push rod 206 pushes the parts upward from the inner cavity of the placement frame 8, thereby completing the automatic unloading of the parts after processing, avoiding the parts from being stuck in the placement frame 8 and unable to be removed, thereby affecting the operator's processing of subsequent parts.

[0028] Example 2

[0029] In one embodiment, the four sliders 202 are slidably connected to the surfaces of the four slide bars 201, the four hard springs 203 are fixedly installed on the outsides of the four sliders 202, the four movable bars 204 are movably connected to the tops of the four sliders 202, the mounting plate 205 is movably connected to the tops of the four movable bars 204, the push rod 206 is fixedly installed on the top of the mounting plate 205, the push plate 207 is fixedly installed on the top of the push rod 206, a displacement groove 208 is opened on the top of the lathe box 1, the push rod 206 passes through the inner cavity of the displacement groove 208 and extends into the inner cavity of the placement frame 8, sliding grooves 209 are opened around the bottom of the inner cavity of the lathe box 1, the bottoms of the four sliders 202 are slidably connected to the inner cavity of the four sliding grooves 209, and a fixing mechanism 3 is provided on the top of the inner cavity of the lathe box 1, and the fixing mechanism 3 includes a motor 301, and the motor 301 is fixedly installed on the lathe At the top of the inner cavity of the bed box 1, the output end of the motor 301 is fixedly connected with the gear 302, and the top of the lathe box 1 is provided with an outer gear ring 303, the front side of the outer gear ring 303 is meshed with the rear side of the gear 302, and the top of the outer gear ring 303 is movably connected with the first connecting plate 304, the tops of the four first connecting plates 304 are movably connected with the second connecting plates 305, the bottoms of the four second connecting plates 305 are movably connected with the mounting blocks 306, and the outer sides of the four mounting blocks 306 are fixedly installed with clamps 307, and the top of the lathe box 1 is provided with limiting grooves 308, and the bottoms of the four mounting blocks 306 are slidably connected in the inner cavities of the four limiting grooves 308. A moving groove 309 is provided on the top of the lathe box 1, and moving blocks 310 are fixedly installed around the bottom of the outer gear ring 303, and the four moving blocks 310 are slidably connected in the inner cavity of the moving groove 309.

[0030] By setting the movable rod 204, the downward pressure on the parts during processing can be converted into an outward thrust. When the processing is completed, the hard spring 203 can drive the equipment to unload the processed parts through its own tension, so that they can be moved out of the inner cavity of the placement frame 8. By setting the displacement groove 208, the push rod 206 can be limited when it moves, avoiding the push rod 206 from deviating when it moves, thereby affecting the automatic unloading of the parts. By setting the sliding groove 209, the moving direction of the slider 202 can be limited to avoid changing its moving direction, thereby affecting the processing. After the work is completed, the unloading work of the parts can be done by setting a fixing mechanism 3 to fix the parts during processing, so as to avoid shaking of the parts during processing, which may cause deviation in the processing position and affect the subsequent use of the parts. By setting a limiting groove 308, the mounting block 306 can be limited to avoid deviation when the mounting block 306 moves, which may affect the clamping of the parts. By setting a moving block 310 and a moving groove 309, the outer tooth ring 303 can be supported while preventing its position from being offset during rotation, thereby preventing the clamp 307 from clamping the parts.

[0031] When the utility model is working: after the part is placed on the top of the push plate 207, the cylinder 6 drives the processing device 7 downward to contact the part. At this time, the part moves downward due to the pressure generated by the cylinder 6 and enters the inner cavity of the placement frame 8. At this time, the push plate 207 moves synchronously, and the push rod 206 drives the mounting plate 205 to move downward. The movable rod 204 flips inward due to the movement of the mounting plate 205, and pushes the slider 202 outward to move. As the slider 202 moves, the hard spring 203 is deformed due to the force, and then the output end of the motor 301 drives the gear 302 to rotate, and through the cooperation of the outer gear ring 303, the first connecting plate 304 is pulled to move. As the first connecting plate 304 moves, the second connecting plate 305 drives the mounting block 306 to move inward synchronously. At this time, the clamp 307 follows the mounting block 3 06 moves synchronously inward and clamps the parts, and then the processing device 7 processes the parts. When the processing is completed, the cylinder 6 drives the processing device 7 to move upward, and the motor 301 drives the reverse gear 302 to rotate, and makes the outer gear ring 303 rotate in the opposite direction, pushing the first connecting plate 304, the second connecting plate 305, the mounting block 306 and the clamp 307 to move synchronously outward to release the clamping of the parts. As the clamp 307 is removed from the surface of the part, the hard spring 203 deforms again due to the disappearance of the force, and pushes the slider 202 to move inward through its own tension. At this time, the movable rod 204 flips outward and drives the mounting plate 205, the push rod 206 and the push plate 207 to move upward, and the parts are pushed away to the outside of the placement frame 8 through the upward thrust of the push plate 207, completing the unloading of the parts.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
