Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for the production of mechanical parts. Background Technology

[0002] Mechanical parts, also known as mechanical components, are the basic elements that make up machinery. They are inseparable individual parts that make up machinery and machines. During the production process, mechanical parts need to be cut from the base material or the processed parts to meet the requirements of the manufacturer. Cutting devices are often used for cutting.

[0003] In the prior art, a cutting device for producing mechanical parts, disclosed in CN217832052U, includes a placement table. Fixed plates are installed at both ends of the top of the placement table. A contact mechanism is connected between the lower ends of the two fixed plates. An electric guide rail is connected between the tops of the two fixed plates. A first slider adapted to the electric guide rail is installed on the electric guide rail. A first electric push rod is installed at the bottom end of the first slider. A mounting plate is connected to the bottom output end of the first electric push rod. A first motor, arranged horizontally, is installed at the bottom end of the mounting plate. A cutting blade is connected to one output end of the first motor. By setting the contact mechanism, the stability of the workpiece to be cut can be improved, thereby improving the cutting effect and efficiency of the device.

[0004] The device disclosed in the aforementioned patent uses multiple electric push rods and motors to drive the clamping of parts in order to ensure the clamping state, thereby achieving the effect of lateral clamping and longitudinal pressing. However, the use of multiple drive sources to achieve a single clamping and fixing effect results in technical waste and redundancy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting device for the production of mechanical parts, which has the advantages of stable clamping and automatic centering, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a cutting device for producing mechanical parts, including a frame, a worktable fixedly installed on the top of the frame, a cylinder fixedly installed at the bottom crossbeam of the frame, a clamping device provided on the worktable, a rotating bar rotatably installed at the bottom center of the worktable via a bearing, connecting rod devices connecting the two ends of the rotating bar to the clamping device respectively, and a pressing device symmetrically fixedly installed on the top of the clamping device on the upper surface of the worktable.

[0007] Through the above structural setup, the clamping device and the pressing device work together to achieve automatic centering and stable clamping of the parts. The clamping rollers stably clamp the four sides of the parts, and the clamping rollers achieve both lateral and longitudinal limiting effects.

[0008] Preferably, the workbench has symmetrical grooves on both sides of its surface, a chip groove in the middle of its surface, support platforms fixedly installed on both sides of the chip groove at the top of the workbench, and guide rails evenly distributed on one side of the groove at the bottom of the workbench.

[0009] With the above structural design, a chip groove is created, and the cutting chips generated by the cutting blade during cutting are thrown into the chip groove. At the same time, it works in conjunction with the clamping device and the pressing device to achieve the clamping effect on the parts.

[0010] Preferably, the clamping device includes a base plate and a sliding sleeve. The base plate is disposed below the guide rail, and the sliding sleeve is symmetrically fixedly installed on the surface of the base plate. The sliding sleeve is slidably installed on the outer ring of the guide rail. A top block is fixedly installed on one side of the base plate. One side of the top block is fixedly connected to the end of the output shaft of the cylinder. Side plates are provided on both sides of the base plate inside the sliding groove, and a top plate is fixedly connected between the tops of the side plates.

[0011] With the above structural configuration, when the cylinder pushes or pulls the top block to move through the output shaft, the top block will drive one side of the bottom plate to slide outside the guide rail through the sliding sleeve. When one side of the bottom plate moves, it will push the rotating bar to rotate in a circle through the connecting rod device. The other end of the rotating bar will push or pull the other side of the bottom plate to move in the opposite direction through the connecting rod device, so that when the bottom plate moves, it will drive the top pressing device to clamp or release in the opposite direction.

[0012] Preferably, the connecting rod device includes a screw barrel, a left-hand screw, and a right-hand screw. The screw barrel has a bidirectional threaded groove inside. The end of the left-hand screw is rotatably mounted on both ends of the rotating bar, and the end of the right-hand screw is rotatably mounted on the surface of the base plate. The screw barrel is threadedly sleeved on the outer ring of the screw barrel and the left-hand screw.

[0013] With the above structural design, the screw barrel is driven by the bidirectional threaded groove to move in opposite directions with the left-hand screw. It can simultaneously retract inward or extend outward, thereby adjusting the distance between the end of the rotating bar and the surface of the base plate. By rotating the screw barrel, the sliding stroke of the clamping device can be adjusted.

[0014] Preferably, the top pressing device includes a frame, which is symmetrically and fixedly installed on the surface of the top plate. A fixing cylinder is fixedly installed on the inner top wall of the frame. A V-shaped plate is rotatably installed on the surface of the frame. The bottom of the V-shaped plate is rotatably installed inside the fixing cylinder via a pin. A return spring is fixedly connected between the outer ring of the pin and the inner ring of the fixing cylinder. Pressure wheels are rotatably installed at both ends of the surface of the V-shaped plate. The pressure wheels are made of polyurethane material. A limiting post is provided on one side of the V-shaped plate on the surface of the frame.

[0015] With the above structure, one side of the clamping wheel first contacts the lateral side of the part, and then the V-shaped plate rotates inside the fixed cylinder through the extrusion force, while the return spring is tightened, so that the other side of the clamping wheel contacts the longitudinal side of the part during the rotation process. After clamping, the clamping wheels clamp the part in the lateral and longitudinal directions respectively.

[0016] This utility model has the following advantages: 1. This cutting device for producing mechanical parts achieves clamping through a single drive source by setting up a worktable, cylinder, clamping device, and top pressing device. By setting up a single cylinder, the output shaft drives the top block on one side of the base plate to move. While the base plate slides between the outer ring of the guide rail and the slide groove, the connecting rod between the base plate and the rotating bar can push the rotating bar to rotate. After the rotating bar rotates, the connecting rod between the other end and the other side of the base plate pushes the clamping device to move in opposite directions. This avoids redundancy in the mechanical structure and solves the clamping drive problem with a single drive source. Furthermore, the lateral and longitudinal limiting of the parts by the pressure rollers does not weaken the clamping effect, achieving stable clamping with a single drive source.

[0017] 2. This cutting device for producing mechanical parts achieves stable clamping of parts through a structure including a cylinder, clamping device, and top pressing device. The cylinder pulls the top block to slide via its output shaft. The top block drives the base plate to slide on the guide rail surface via a sliding sleeve. The base plate moves the top plate via a side plate and rotates the rotating bar via a connecting rod device. The rotating bar pulls the other side base plate via another connecting rod device, causing the base plates to move in opposite directions. During the movement, the top plate drives the top pressing device to move synchronously towards the part position. After one side of the clamping wheel contacts the part, the resistance and extrusion force push the V-shaped plate to rotate inside the fixed cylinder via a pin shaft, and drive the other side of the clamping wheel to approach the longitudinal side of the part. After the other side of the clamping wheel contacts the longitudinal side of the part, the cylinder stops working. At this time, the clamping wheels fix the workpiece laterally and longitudinally, achieving a stable clamping effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 A cutting device for producing mechanical parts includes a frame 1, a worktable 2 fixedly mounted on the top of the frame 1, a cylinder 3 fixedly mounted on the bottom crossbeam of the frame 1, a clamping device 4 on the worktable 2, a rotating bar 5 rotatably mounted on the bottom center of the worktable 2 via a bearing, a connecting rod device 6 connecting the two ends of the rotating bar 5 to the clamping device 4 respectively, and a pressing device 7 symmetrically fixedly mounted on the top of the clamping device 4 on the upper surface of the worktable 2.

[0022] In actual use, this device achieves automatic centering and stable clamping of parts through the setting and cooperation of clamping device 4 and top pressing device 7. Cylinder 3 pushes or pulls base plate 41 through its output shaft to slide outside guide rail 24 via sliding sleeve 42. When base plate 41 slides, it drives the other side base plate 41 to slide inside slide groove 21 through the restriction and cooperation of connecting rod device 6 and rotating bar 5, realizing bidirectional synchronous movement to clamp parts. When base plate 41 drives top plate 44 to move in the opposite direction to clamp inward, one side pressure wheel 75 first contacts the side of the part. Then, due to the squeezing force between clamping device 4 and part, the top pressing device 7 will cause V-shaped plate 73 to rotate around the pin shaft during the movement, causing the other side pressure wheel 75 to contact the other side of the part, realizing stable clamping of the four sides of the part by pressure wheel 75. Furthermore, the clamping of the part by pressure wheel 75 achieves the effect of lateral and longitudinal limiting. During use, this device uses a single cylinder 3 to drive the top block 43 on one side of the base plate 41 through its output shaft. This causes the base plate 41 to slide within the guide rail 24 and the slide groove 21. Simultaneously, the connecting rod 6 between the base plate 41 and the rotating bar 5 drives the rotating bar 5 to rotate. After the rotating bar 5 rotates, the connecting rod 6 between its other end and the other base plate 41 drives the clamping device 4 to move in opposite directions. This avoids redundancy in the mechanical structure, solves the clamping drive problem with a single drive source, and does not weaken the clamping effect of the parts by using the lateral and longitudinal limiting of the clamping wheels 75.

[0023] Please see Figures 1-2 The workbench 2 has symmetrical grooves 21 on both sides of its surface and a chip groove 22 in the middle of its surface. The chip groove 22 is provided to prevent the cutting blade from contacting the surface of the workbench 2 during cutting. The cutting chips generated by the cutting blade during cutting will be thrown into the chip groove 22. The user can collect the cutting chips by connecting an external negative pressure system or a storage box. The top of the workbench 2 is fixedly installed with support platforms 23 on both sides of the chip groove 22. There are also grooves of the same size as the chip groove 22 between the support platforms 23, so that the chip groove 22 can hold more cutting chips. The bottom of the workbench 2 is evenly provided with guide rails 24 on one side of the groove 21.

[0024] Please see Figures 1-2 The clamping device 4 includes a base plate 41 and a sliding sleeve 42. The base plate 41 is located below the guide rail 24. The sliding sleeve 42 is symmetrically fixedly installed on the surface of the base plate 41. The sliding sleeve 42 is slidably installed on the outer ring of the guide rail 24. A top block 43 is fixedly installed on one side of the base plate 41. One side of the top block 43 is fixedly connected to the end of the output shaft of the cylinder 3. Side plates are provided on both sides of the base plate 41 inside the slide groove 21. A top plate 44 is fixedly connected between the tops of the side plates.

[0025] When the cylinder 3 pushes or pulls the top block 43 to move through the output shaft, the top block 43 will drive one side of the bottom plate 41 to slide outside the guide rail 24 through the sliding sleeve 42. Then the bottom plate 41 drives the top plate 44 to slide through the side plate. When one side of the bottom plate 41 moves, it pushes the rotating bar 5 to rotate in a circle through the connecting rod device 6. The other end of the rotating bar 5 pushes or pulls the other side of the bottom plate 41 to move in the opposite direction through the connecting rod device 6, so that when the bottom plate 41 moves, it drives the top pressing device 7 to clamp or release in the opposite direction.

[0026] Please see Figures 1-3 The connecting rod device 6 includes a screw barrel 61, a left-hand screw 62, and a right-hand screw 63. The screw barrel 61 has a bidirectional threaded groove inside. The ends of the left-hand screw 62 are rotatably mounted on both ends of the rotating bar 5, and the ends of the right-hand screw 63 are rotatably mounted on the surface of the base plate 41. The screw barrel 61 is threadedly sleeved on the outer ring of the screw barrel 61 and the left-hand screw 62. The threads between the screw barrel 61, the left-hand screw 62, and the right-hand screw 63 are compatible. In use, by rotating the screw barrel 61, the screw barrel 61 drives the screw barrel 61 and the left-hand screw 62 to move in opposite directions through the bidirectional threaded groove. They can simultaneously retract inward or extend outward, thereby adjusting the distance between the end of the rotating bar 5 and the surface of the base plate 41. By rotating the screw barrel 61, the sliding stroke of the clamping device 4 can be adjusted.

[0027] Please see Figures 1-4 The top pressing device 7 includes a frame 71, which is symmetrically fixedly installed on the surface of the top plate 44. A fixed cylinder 72 is fixedly installed on the inner top wall of the frame 71. A V-shaped plate 73 is rotatably installed on the surface of the frame 71. The bottom of the V-shaped plate 73 is rotatably installed inside the fixed cylinder 72 through a pin. A return spring 74 is fixedly connected between the outer ring of the pin and the inner ring of the fixed cylinder 72. Pressure rollers 75 are rotatably installed at both ends of the surface of the V-shaped plate 73. The pressure rollers 75 are made of polyurethane material and have high friction when clamping parts, which can limit the position of the parts. A limiting post 76 is provided on one side of the V-shaped plate 73 on the surface of the frame 71 to limit the original angle of the V-shaped plate 73.

[0028] When the top pressing device 7 is working, it is driven to move by the clamping device 4. When it slides inward to clamp, one side of the pressing wheel 75 first contacts the lateral side of the part. Then, through the pressing force, the V-shaped plate 73 rotates inside the fixed cylinder 72 through the pin. The return spring 74 is pulled tight, so that the other side of the pressing wheel 75 contacts the longitudinal side of the part during the rotation. After clamping, the pressing wheel 75 clamps the part in the lateral and longitudinal directions respectively, so that the position of the part is firmly restricted and the part sits on the surface of the support platform 23 and cannot be moved.

[0029] Working principle: In use, the part to be cut is placed on the surface of the support table 23. Then, by rotating the screw barrel 61, the screw barrel 61 drives the left-hand screw 62 and the right-hand screw 63 to retract or extend in opposite directions inside the screw barrel 61. Adjust the stroke distance between the clamping device 4 and the rotating bar 5. At this time, the cylinder 3 is started. The cylinder 3 pulls the top block 43 to slide through the output shaft. The top block 43 drives the base plate 41 to slide on the surface of the guide rail 24 through the sliding sleeve 42. The base plate 41 drives the top plate 44 to move through the side plate. During the movement, the base plate 41 pushes the connecting rod device 6 to make the rotating bar 5 rotate. At the same time, the rotating bar 5 pulls the other side of the base plate 41 to move through the other end of the connecting rod device 6. The bottom plates 41 move in opposite directions. During the movement, the top plate 44 drives the pressing device 7 to move synchronously towards the part position. When one side of the pressing wheel 75 contacts the lateral side of the part, the pressing wheel 75 pushes the V-shaped plate 73 to rotate inside the fixed cylinder 72 through the pin due to resistance and extrusion force. When the V-shaped plate 73 rotates, it pulls the return spring 74 and drives the other side of the pressing wheel 75 to approach the longitudinal side of the part. After the other side of the pressing wheel 75 contacts the longitudinal side of the part, the cylinder 3 stops working. At this time, the pressing wheels 75 fix the workpiece in both the lateral and longitudinal directions. Since the part is located on the surface of the support platform 23, the pressing wheels 75 can achieve automatic centering during the clamping process.
