Description

Technical Field

[0001] This utility model relates to the technical field of lawnmower accessories, and in particular to a clamping device for fixed-length cutting of lawnmower handle parts. Background Technology

[0002] A lawnmower is a mechanical tool used for trimming lawns, vegetation, etc., and is also known as a lawn mower, lawn trimmer, or lawn mower. It mainly consists of a blade disc, engine, wheels, a walking mechanism, blades, a handle, and a control unit. The working principle of a lawnmower is that the high-speed rotation of the engine drives the blades or nylon rope to rotate, thereby cutting grass and small shrubs.

[0003] The handle of a lawnmower is generally made of steel pipe. During production, the steel pipe needs to be cut to a fixed length according to the size requirements. Cutting a single steel pipe at a time is inefficient. Therefore, multiple steel pipes can be clamped simultaneously and cut at once. This requires clamping equipment that can clamp multiple steel pipes simultaneously and ensure uniform size. However, with movable clamping equipment, the cut steel pipes fall into the gaps and are difficult to remove. Therefore, clamping equipment is needed to effectively support the fallen steel pipes to prevent them from falling and facilitate rapid discharge. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing a clamping device for fixed-length cutting of lawnmower handle parts.

[0005] This utility model is achieved through the following technical solution:

[0006] A clamping device for fixed-length cutting of lawnmower handles includes a base, a top plate, a guide frame, a hydraulic cylinder, a first support assembly, a second support assembly, a limiting screw, a connecting plate, a flip plate, and support wheels. The top plate is fixedly disposed inside one side of the base, the guide frame is fixedly disposed inside the bottom of the base, the hydraulic cylinder is fixedly disposed outside the base, the first support assembly is fixedly disposed at the telescopic end of the hydraulic cylinder, the second support assembly is clamped on the top of the guide frame, and the limiting screw is fixed inside one side of the base. The first support assembly includes a first support seat, a first support plate, and a second support plate. The first support plate and the second support plate are fixedly disposed on the top of the first support seat, and the bottom of the first support seat is clamped on the top of the guide frame.

[0007] In a preferred embodiment of this utility model, the second support assembly includes a second support base, a locking plate, a guide seat, a pressure applying frame, a telescopic rod, a pressure applying seat, a locking bead, an insert rod, and a knob. The locking plate is fixedly disposed on the top of the second support base, the guide seat is fixedly disposed on both ends of the second support base, the pressure applying frame is locked on the top of the guide seat, the telescopic rod is fixedly disposed on the inner side of the top of the pressure applying frame, the pressure applying seat is fixedly disposed on the bottom end of the telescopic rod, the locking bead is movably connected to the bottom of the pressure applying seat, the insert rod is fixedly disposed on the bottom of both ends of the pressure applying seat, and the knob is threadedly connected to the insert rod.

[0008] The second support component mainly provides effective support for the steel pipe at the cutting end and clamps and fixes it, thereby facilitating the steel pipe cutting work.

[0009] In a preferred embodiment of the present invention, the support wheel is installed between the first support plate, the second support plate, and the clamping plate, the connecting plate is installed at both ends of the first support base and the second support base, and the flip plate is movably connected to the connecting plate.

[0010] The support wheels facilitate the forward movement of the steel pipe for feeding and provide effective support at the bottom of the steel pipe.

[0011] In a preferred embodiment of the present invention, one end of the limiting screw passes through the first support base and the second support base and extends to the outside of one side of the second support base. On both sides of the second support base, limiting nuts are provided on the surface of the limiting screw.

[0012] After adjusting the position of the first support component by sliding it on the surface of the limiting screw, limiting nuts are installed on both sides of the first support seat on the surface of the limiting screw to achieve the effect of positioning and fixing the first support component.

[0013] In a preferred embodiment of this utility model, the bottom of the insertion rod extends through and to the outer side of the bottom of the guide seat, and the top of the knob contacts the bottom of the guide seat;

[0014] Rotating the knob controls the descent of the pressure frame, causing the telescopic rod to contract under pressure. The reaction force of the internal spring acts on the pressure seat, and the locking ball applies pressure to the top of the steel pipe, thereby effectively clamping the end of the steel pipe.

[0015] In a preferred embodiment of the present invention, the top of the second support plate is provided with a slot that mates with the top plate;

[0016] The hydraulic cylinder retracts, causing the first support assembly to move backward, thereby inserting the top plate into the top slot of the second support plate. The top plate then rests against the end of the steel pipe, causing one end of the steel pipe to fall from the first support assembly, facilitating the steel pipe collection process.

[0017] The beneficial effects of this utility model are:

[0018] The handle of this lawnmower uses a clamping device for fixed-length cutting to effectively support both ends of the steel pipe and clamp and fix the cutting end. After cutting, the clamped end of the steel pipe falls off, causing its end to fall onto the flip plate surface inside the second support base. Then, the hydraulic cylinder retracts, and the top plate pushes the other end of the steel pipe off the top of the first support base. The falling steel pipe is effectively supported by the flip plate, preventing it from falling into the gap, thus facilitating the collection of finished products. Attached Figure Description

[0025] like Figure 1-4The shown is a clamping device for fixed-length cutting of lawnmower handle, including a base 1, a top plate 2, a guide frame 3, a hydraulic cylinder 4, a first support assembly 5, a second support assembly 6, a limiting screw 7, a connecting plate 8, a flip plate 9, and a support wheel 10. The top plate 2 is fixedly installed inside one side of the base 1, the guide frame 3 is fixedly installed inside the bottom of the base 1, the hydraulic cylinder 4 is fixedly installed outside the base 1, the first support assembly 5 is fixedly installed at the telescopic end of the hydraulic cylinder 4, the second support assembly 6 is clamped on the top of the guide frame 3, and the limiting screw 7 is fixed inside one side of the base 1. The first support assembly 5 includes a first support seat 51, a first support plate 52, and a second support plate 53. The first support plate 52 and the second support plate 53 are fixedly installed on the top of the first support seat 51, and the bottom of the first support seat 51 is clamped on the top of the guide frame 3.

[0026] Specifically, the second support assembly 6 includes a second support base 61, a locking plate 62, a guide seat 63, a pressure frame 64, a telescopic rod 65, a pressure seat 66, a locking bead 67, an insert rod 68, and a knob 69. The locking plate 62 is fixedly disposed on the top of the second support base 61, the guide seat 63 is fixedly disposed on both ends of the second support base 61, the pressure frame 64 is locked on the top of the guide seat 63, the telescopic rod 65 is fixedly disposed on the inner side of the top of the pressure frame 64, the pressure seat 66 is fixedly disposed on the bottom end of the telescopic rod 65, the locking bead 67 is movably connected to the bottom of the pressure seat 66, the insert rod 68 is fixedly disposed on the bottom of both ends of the pressure seat 66, and the knob 69 is connected to the insert rod 68. The support wheel 10 is installed between the first support plate 52, the second support plate 53, and the clamping plate 62 via a threaded connection. The connecting plate 8 is installed at both ends of the first support base 51 and the second support base 61. The flip plate 9 is movably connected to the connecting plate 8. One end of the limiting screw 7 passes through the first support base 51 and the second support base 61 and extends to the outside of one side of the second support base 61. On both sides of the second support base 61, limiting nuts are provided on the surface of the limiting screw 7. The bottom of the insert rod 68 passes through and extends to the outside of the bottom of the guide seat 63. The top of the knob 69 contacts the bottom of the guide seat 63. The top of the second support plate 53 has a slot that mates with the top plate 2.

[0027] In this embodiment, the cylinder 4 is in the extended state. At this time, the top plate 2 will not interfere with the installation of the steel pipe. The steel pipe is placed between the first support plate 52 and the clamping plate 62. The bottom of the steel pipe is effectively supported by the support wheel 10. One end of the steel pipe is in contact with the inner side of the second support plate 53. After the position of the second support seat 61 is adjusted at the top of the guide frame 3, the limiting nut is rotated so that the limiting nuts on the surface of the limiting screw 7 are respectively set on both sides of the second support seat 61, so that it can play the role of limiting and fixing the second support seat 61. Then the pressure frame 64 is installed. After the insertion rod 68 is inserted into the bottom hole of the guide seat 63, both ends of the pressure frame 64 are inserted into the guide seat 63. Then the knob 69 is screwed into the insertion rod 68. As the knob 69 is tightened, the telescopic rod 65 retracts, so that the clamping ball 67 applies pressure to the top of the steel pipe to achieve the effect of clamping and fixing.

[0028] Furthermore, the cutting machine performs a fixed-length cutting operation inside the second support assembly 6, near the position of the second support assembly 6. After cutting, one end of the steel pipe falls to the top of the flip plate 9 inside the second support base 61. Then, the hydraulic cylinder 4 retracts, driving the entire first support assembly 5 to move backward, so that the top plate 2 is inserted into the top slot of the second support plate 53, causing it to push the top of the steel pipe down, so that both ends of the steel pipe fall onto the top of the flip plate 9 inside the first support base 51 and the second support base 61, respectively. The flip plate 9 effectively prevents the steel pipe from falling into the gap between the guide frames 3, thus facilitating the finished product picking operation.
