Description

Technical Field

[0001] The present invention belongs to the technical field of slotting machines, and more particularly relates to a linear slotting machine for metal parts. Background Art

[0002] In the field of metal parts processing, especially the grooving of metal tubes, traditional linear grooving machines have many problems that need to be solved.

[0003] From the perspective of metal pipe loading and support, traditional slotting machines often lack a suitable auxiliary loading structure, making metal pipe installation difficult and positioning inaccurate. Manual placement of the metal pipe in the designated position is often laborious, inefficient, and difficult to ensure accurate placement each time. This directly impacts the accuracy and stability of subsequent slotting. Furthermore, existing support structures are mostly single, flat supports that cannot dynamically adjust to the movement of the metal pipe. This can easily cause excessive pressure on the metal pipe during securing, leading to deformation and compromising product quality.

[0004] In terms of clamping and fixing, traditional slotting machines use a relatively simple clamping system, often employing two-way support. This provides insufficient stability for securing the metal pipe. During the slotting process, the metal pipe is prone to rotation or deflection, resulting in positional deviations and severely impacting machining accuracy. Furthermore, traditional clamping mechanisms are mostly rigid, which can easily damage the metal pipe surface when securing it, reducing the product's appearance quality and service life.

[0005] Traditional slotting machines typically require manual removal of the finished metal pipe and adjustment of machine components back to their original positions after processing. This process not only increases labor costs and intensity, but also consumes significant time and reduces overall processing efficiency. Furthermore, manual operation is prone to errors, affecting the repeatability of the machine and, consequently, the stability of subsequent processing quality.

[0006] In summary, the existing metal tube linear grooving machines have obvious deficiencies in the loading support, clamping and fixing, and discharging and resetting of metal tubes, and cannot meet the requirements of modern metal parts processing for high efficiency, high precision and high quality. Summary of the Invention

The interlocking structures are pivotally connected to each other with a set of interlocking structures. The interlocking structures are pivotally connected to each other with a set of interlocking structures.

[0010] Preferably, a motor is fixedly installed at the bottom of the gripping base, a threaded column is rotatably installed inside the gripping base, the output shaft of the motor is fixedly connected to the bottom of the threaded column, and a lifting platform is installed on the surface of the threaded column through a thread, a first connecting frame is fixedly installed under each first gripping clamp, at least two cross plates are fixedly installed on the inner wall of each first gripping clamp, and each first connecting frame is fixedly connected to the top of the gripping clamp base, a third connecting frame is rotatably installed on the side wall of each first gripping clamp, a second connecting frame is rotatably installed on the end of each third connecting frame, and each second connecting frame is fixedly connected to the top of the lifting platform, the second gripping clamp has the same connection mechanism as the first gripping clamp, and the third connecting frame on the second gripping clamp is longer than the third connecting frame on the first gripping clamp, a side support rod is fixedly installed on the side wall of the gripping clamp base, and a fourth spring assembly is installed above the side support rod, and the fourth spring assembly is located below the second gripping clamp, a fixed floor is fixedly installed on the side wall of each fixed sleeve plate, and the fixed floor is fixedly connected to the side walls of the first gripping clamp and the second gripping clamp, and a spring is fixedly installed between each fixed floor and the guide column.

[0011] Preferably, the side walls of the gripping base are provided with side openings, the side walls of the lifting platform are fixedly installed with connecting rods, and the connecting rods are located in the side openings, open frames are fixedly installed on both sides of the connecting rods, and a transverse support rod is installed inside each opening frame, a third spring assembly is fixedly installed between the bottom of each transverse support rod and the inner wall of the opening frame, and each transverse support rod is located between two support plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, in the initial state, the heights of the first U-shaped support frame and the two second U-shaped support frames are higher than the two gripping bases, and the metal pipe moves from the two second U-shaped support frames to the first U-shaped support frame. When the metal pipe moves to the first U-shaped support frame, the lower support plate moves sideways. At this time, the first U-shaped support frame and the second U-shaped support frame move downward, and drive the metal pipe to move down to the gripping base. At this time, the motor in the gripping base drives the first gripper and the second gripper to clamp the metal pipe, and then starts the upper driving assembly to drive the upper fixed frame to move downward, and the second driving assembly inside the upper fixed frame then drives the grooving cutter body to move, and the grooving cutter body repeatedly moves in a straight line in the upper fixed frame and grooves the surface of the metal pipe, effectively protecting the metal pipe from being squeezed and deformed due to excessive clamping force of the gripping base during grooving, and the grooving is more stable.

[0013] The first U-shaped support frame is moved downwards by the first U-shaped support frame, and the second U-shaped support frame is moved downwards by the first U-shaped support frame. The second spring assembly is compressed when the first U-shaped support frame moves downwards, and the tripod is driven downwards to contact the upper sliding plate. The inclined surface of the upper sliding plate end is fitted with the inclined surface of the tripod. The upper sliding plate is forced to move to the other side. Ball bearings are provided under the legs, so the upper sliding plate will move under the supporting legs. The movement of the upper sliding plate drives the rectangular groove to move, and then the supporting legs fall into the rectangular groove and drive the second U-shaped support frame to move downward. The second U-shaped support frame drives the second spring assembly to compress downward, and multiple second spring assemblies will drive the metal pipe to move slowly downward. When the metal pipe moves to above the clamping base, it stops. By using the first U-shaped support frame and the second U-shaped support frame to support the metal pipe in advance, the installation of the metal pipe can be facilitated. The first U-shaped support frame and the second U-shaped support frame are arranged in sections, which can ensure the supporting force of the subsequent grooving and greatly reduce the pressure on the metal pipe when it is fixed.

[0014] In the present invention, the motor drives the threaded column to rotate, and the rotation of the threaded column drives the lifting platform to move downward. The downward movement of the lifting platform drives the second connecting frame to move downward, and the downward movement of the second connecting frame drives the third connecting frame to move downward. The third connecting frame moves downward to pull the first grabbing clamp toward the metal pipe, and the two third connecting frames are staggered to wrap the metal pipe. Each first grabbing clamp can fit evenly on the surface of the metal pipe, and the cross plate can provide better support for the first grabbing clamp. At this time, the metal pipe is tightly fixed by the two first grabbing clamps, and the second grabbing clamp is pulled upward to rotate. The second grabbing clamp provides horizontal support to the metal pipe. The two first grabbing clamps and the second grabbing clamp provide three-way fixed support for the metal pipe, which is more stable than the traditional two-way support.

[0015] In the present invention, each first gripping clamp and second gripping clamp has a certain toughness, so it can flexibly support the metal tube and fit the metal tube more tightly, thereby avoiding the phenomenon of the metal tube being clamped by the clamp when fixing, and effectively preventing the metal tube from rotating and deflecting during processing.

[0016] In the present invention, the lifting platform drives the first gripping clamp and the second gripping clamp to release. At the same time, the lifting platform moves upward, driving the opening frame and the horizontal support rod to move upward. The horizontal support rod moves upward, driving the support plates on both sides to move upward. The support plate moves upward, driving the first U-shaped support frame and the second U-shaped support frame to move upward. At this time, the metal tube is pushed upward. After the metal tube moves upward, it is convenient to discharge the material. At the same time, the end of the lower support plate is pushed by the two first spring assemblies to move, and the lower support plate moves and resets to prepare for the next processing. The whole does not require manual reset, has strong automation capabilities, and shortens the overall processing time. BRIEF DESCRIPTION OF THE DRAWINGS

A movable first gripping clamp 4 and a second gripping clamp 46 are provided above each gripping base 31. The side wall of each first gripping clamp 4 is provided with at least two fixed sleeves 42. A freely retractable guide column 44 is installed inside each fixed sleeve 42. The guide column 44 is used to fix the metal pipe 16. The metal pipe 16 is inserted from the right side of the slotting machine body 1. The first drive assembly and the second drive assembly 12 are both composed of a motor and a threaded rod, and the threaded rod is fixed to the output shaft of the motor. In the initial state, the height of the first U-shaped support frame 23 and the two second U-shaped support frames 25 is higher than the two clamping bases 31, and the metal tube 16 moves from the two second U-shaped support frames 25 to the first U-shaped support frame 23. When the metal tube 16 moves to the first U-shaped support frame 23, the lower support plate 18 moves sideways. At this time, the first U-shaped support frame 23 and the second U-shaped support frame 25 move downward, and drive the metal tube 16 to move downward to the clamping base. On the base 31, at this time, the motor in the clamping base 31 is driven to drive the first clamp 4 and the second clamp 46 to clamp the metal pipe 16, and then the upper drive component 14 is started to drive the upper fixed frame 11 to move downward, and the second drive component 12 inside the upper fixed frame 11 then drives the grooving cutter body 13 to move. The grooving cutter body 13 repeatedly moves linearly in the upper fixed frame 11 and grooves the surface of the metal pipe 16, effectively protecting the metal pipe 16 from being squeezed and deformed due to excessive clamping force of the clamping base 31 during grooving, and the grooving is more stable.

[0021] The upper fixed frame 11 and the upper driving assembly 14 are both fixedly connected to the groover body 1, and the side wall of the upper fixed frame 11 is provided with a second driving assembly 12 for driving the groover cutter body 13 to move. Two first driving assemblies for driving the upper fixed frame 11 to move up and down are provided inside the upper driving assembly 14. The inner wall of the groover body 1 below the upper sliding plate 19 is fixedly installed with a lower support plate 18. The left side of the groover body 1 is the discharging end. The upper sliding plate 19 is provided with an inclined surface 21 on one side of the discharging end. Two tripods 24 are fixedly installed under the support plate 15 below the first U-shaped support frame 23, and the inclined surface of the tripod 24 faces the inclined surface 21.

When in use, the metal tube 16 first moves to the two second U-shaped support frames 25, and the two second U-shaped support frames 25 are supported by the support legs 26 at the bottom, and the support legs 26 are supported by the lower support The plate 18 supports, and at this time the metal tube 16 can be stably supported by the two second U-shaped support frames 25. When the metal tube 16 moves onto the first U-shaped support frame 23, since the first U-shaped support frame 23 is higher than the second U-shaped support frame 25, the first U-shaped support frame 23 is forced to move downward, and the first U-shaped support frame 23 moves downward to compress the second spring assembly 22, and drive the tripod 24 to move downward, and the tripod 24 moves downward to contact the upper sliding plate 19, and the inclined surface 21 at the end of the upper sliding plate 19 fits with the inclined surface of the tripod 24. The upper sliding plate 19 is forced to move to the other side, and a ball bearing is provided under each supporting leg 26, so the upper sliding plate 19 will be under the supporting leg 26. The upper sliding plate 19 moves, driving the rectangular groove 2 to move, and then the supporting leg 26 falls into the rectangular groove 2, and drives the second U-shaped support frame 25 to move downward, and the second U-shaped support frame 25 drives the second spring assembly 22 to compress downward, and multiple second spring assemblies 22 will drive the metal tube 16 to move downward slowly, and stop when the metal tube 16 moves above the clamping base 31. By using the first U-shaped support frame 23 and the second U-shaped support frame 25 to support the metal tube 16 in advance, the metal tube 16 can be easily installed. The first U-shaped support frame 23 and the second U-shaped support frame 25 are arranged in sections, which can ensure the supporting force of the subsequent grooving, and greatly reduce the pressure on the metal tube 16 when it is fixed; The first U-shaped support frame 23 and the second U-shaped support frame 25 will move downward simultaneously with the support plate 15. The support plate 15 moves downward to contact the transverse support rod 3 and drives the transverse support rod 3 to move in the open frame 28. The movement of the transverse support rod 3 will compress the third spring assembly 29.

[0022] The bottom of the clamping base 31 is fixedly installed with a motor, and the inside of the clamping base 31 is rotatably installed with a threaded column 35. The output shaft of the motor is fixedly connected to the bottom of the threaded column 35, and a lifting platform 36 is installed on the surface of the threaded column 35 through a thread. A first connecting frame 37 is fixedly installed under each first clamp 4, and at least two cross plates 41 are fixedly installed on the inner wall of each first clamp 4, and each first connecting frame 37 is fixedly connected to the top of the clamping base 31.

A side support rod 33 is fixedly installed on the side wall of the clamping base 31, and a fourth spring assembly 34 is installed above the side support rod 33. The assembly 34 is located below the second gripping clamp 46. When in use, when the metal pipe 16 moves down to above the gripping base 31, the motor at the bottom of the gripping base 31 is started, and the motor drives the threaded column 35 to rotate. The rotation of the threaded column 35 drives the lifting platform 36 to move downward. The lifting platform 36 moves downward to drive the second connecting frame 38 to move downward. The second connecting frame 38 moves downward to drive the third connecting frame 39 to move downward. The third connecting frame 39 moves downward to pull the first gripping clamp 4 toward the metal pipe 16. The two third connecting frames 39 are staggered to wrap the metal pipe 16. Each first gripping clamp 4 can be evenly attached to the surface of the metal pipe 16. At the same time, the cross plate 41 can provide better support for the first gripping clamp 4. At this time, the metal pipe 16 is tightly fixed by the two first gripping clamps 4. At the same time, the second gripping clamp 46 is pulled upward and rotated. The second gripping clamp 46 supports the metal pipe 16 laterally. The two first gripping clamps 4 and the second gripping clamps 46 provide three-way fixed support for the metal pipe 16, which is more stable than the traditional two-way support. Each of the first gripping clamp 4 and the second gripping clamp 46 has a certain toughness, so it can flexibly support the metal tube 16 and fit the metal tube 16 more tightly, thereby avoiding the metal tube 16 being clamped by the clamp when fixed, and effectively preventing the metal tube 16 from rotating and deflecting during processing.

[0023] A fixed floor 43 is fixedly installed on the side wall of each fixed sleeve 42, and the fixed floor 43 is fixedly connected to the side walls of the first gripping clamp 4 and the second gripping clamp 46.

When in use, multiple guide columns 44 on the surface of the first gripping clamp 4 and the second gripping clamp 46 are in contact with the surface of the metal tube 16, and the multiple guide columns 44 are retracted and moved under force. The ends of the multiple guide columns 44 are tightly fitted with the surface of the metal tube 16, which provides greater friction for fixing the first gripping clamp 4 and the second gripping clamp 46. At the same time, each guide column 44 moves independently and can change according to the shape of the surface of the metal tube 16, further improving the fixing ability of the metal tube 16.

[0024] The side walls of the clamping base 31 are each provided with a side opening 32, and the side walls of the lifting platform 36 are fixedly installed with a connecting rod 27, and the connecting rod 27 is located in the side opening 32, and opening frames 28 are fixedly installed on both sides of the connecting rod 27, and a transverse support rod 3 is installed inside each opening frame 28, and a third spring assembly 29 is fixedly installed between the bottom of each transverse support rod 3 and the inner wall of the opening frame 28, and each transverse support rod 3 is located between the two support plates 15.

The first gripper 4 and the second gripper 46 are released. At the same time, the lifting platform 36 moves upward, driving the opening frame 28 and the horizontal support rod 3 to move upward. The horizontal support rod 3 moves upward, driving the support plates 15 on both sides to move upward. The support plates 15 move upward, driving the first U-shaped support frame 23 and the second U-shaped support frame 25 to move upward. At this time, the metal tube 16 is pushed upward. After the metal tube 16 moves upward, it is convenient to discharge the material. At the same time, the end of the lower support plate 18 is pushed by the two first spring assemblies 17 to move, and the lower support plate 18 moves and resets to prepare for the next processing. There is no need for manual reset as a whole, the automation capability is strong, and the overall processing time is shortened.
