Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of chamfering equipment, in particular to a chamfering equipment for track preparation. BACKGROUND

[0002] The chamfering equipment for track preparation is an automatic machine for chamfering both ends of a track pin shaft, which eliminates burrs and sharp edges through high-precision cutting, turning and grinding processes, ensures smooth insertion of the guide pin shaft into the link hole, reduces the difficulty of centering during assembly, and is widely used in track production lines of heavy equipment such as engineering machinery.

This application can make the pin shafts placed in the box fall into the clamping assembly one by one through the structural design of the control assembly during processing, thereby reducing the risk of multiple pin shafts falling into the clamping assembly at the same time.

Although the above-mentioned chamfering machine can make multiple pin shafts fall into the clamping one by one and reduce the risk of multiple pin shafts falling at the same time, the traditional track chamfering machine can usually only chamfer one end of the pin shaft. After the chamfering of this end is completed, the pin shaft needs to be turned around and chamfered on the other end. This step-by-step chamfering process can ensure the accuracy of chamfering, but it needs to be frequently loaded and the direction of the pin shaft needs to be adjusted, which not only increases the complexity of the operation, but also significantly reduces the chamfering efficiency.

The four knives are controlled separately, one knife is used to chamfer one end of the pin shaft, so that the chamfering can be flexibly switched between the two ends and one end of the pin shaft, and the adaptability of the track preparation chamfering equipment is improved.

[0024] The through hole of the fixing base 11 is rotationally connected with a limiting cylinder 2; the central outer wall of the limiting cylinder 2 is fixedly connected with a gear 21, and the fixing base 11 is internally provided with a motor and connected with the gear 21; the two ends of the gear 21 are both fixedly connected with an extension plate 22; the extension plate 22 is slidably connected with a clamping block 23 through a second electric sliding block, and the opposite side of the two clamping blocks 23 is provided with a V-shaped groove; when the track pin is chamfered, the pin is inserted into the limiting cylinder 2 in the through hole, and after the pin is centered, a plurality of second electric sliding blocks respectively drive the clamping blocks 23 to slide on the extension plate 22 close to the pin, so that the two ends of the pin are clamped by the two opposite clamping blocks 23, and then the motor internally provided in the fixing base 11 drives the gear 21 to rotate rapidly to chamfer, thereby achieving the effect of fixing the track pin; The opposite side of the two clamping blocks 23 is provided with a V-shaped groove, and the two clamping blocks 23 can be adaptively clamped to pins of different thicknesses through the V-shaped groove after being close to each other, thereby improving the adaptability of limiting pins of different thicknesses.

[0025] As shown in Figure 1 , Figure 2 , and Figure 4 , the two sides of the fixing base 11 are fixedly connected with a blanking plate 3, the top surface of the blanking plate 3 is provided with a V-shaped groove, and the blanking plate 3 is inclinedly arranged; when the track pin is chamfered, the pin chamfering is easy to generate waste chips, and the two inclinedly arranged blanking plates 3 are respectively fixed on the two sides of the fixing base 11 to receive the waste chips, and the waste chips can fall along the V-shaped groove on the top surface of the blanking plate 3 after falling, thereby achieving the effect of cleaning the pin chamfering waste chips; At the same time, after the pin chamfering is completed, the pin can also fall on the blanking plate 3 on one side of the fixing base 11 and be guided to fall along the V-shaped groove of one blanking plate 3.

[0026] As shown in Figure 1 , Figure 2 , Figure 4 , and Figure 5 , one side of the machine body 1 is fixedly connected with a fixing frame 4; the top end of the fixing frame 4 is fixedly connected with a fixed plate 41; the inner wall of the fixed plate 41 is fixedly connected with a feeding plate 42; the fixed plate 41 is slidably connected with a push plate 43 through a third electric sliding block, and the side close to the feeding plate 42 of the push plate 43 is provided with a protruding part; when the track pin is fed, a plurality of pins are sequentially placed on the feeding plate 42, and then the third electric sliding block drives the push plate 43 to slide on the fixed plate 41 supported by the fixing frame 4, so that the protruding part of the push plate 43 pushes the pins on the feeding plate 42, and the pins are pushed into the limiting cylinder 2 for clamping, thereby achieving the effect of feeding the pins; When the chamfering of one track pin is completed, the protruding part of the push plate 43 pushes the pin to be processed on the feeding plate 42 to the limiting cylinder 2, so that the pin to be processed can eject the processed pin from the inside of the limiting cylinder 2, thereby achieving the effect of automatic discharging of the pin.

[0027] The top surface of the feeding plate 42 is provided with a V-shaped groove; the protrusion of the push plate 43 is attached to the V-shaped groove of the feeding plate 42; when feeding the track pin, the V-shaped groove on the top surface of the feeding plate 42 limits the placement of the pin, and the pin is tightly attached to the surface of the V-shaped groove of the feeding plate 42, so that the protrusion of the push plate 43 can be attached to the surface of the V-shaped groove of the feeding plate 42 to stably push the pin, thereby improving the stability of feeding the track pin.

[0028] A top material frame 5 is fixedly connected to one side of the fixed plate 41; a top material plate 51 is slidably connected to the inside of the top material frame 5 via a cylinder; a top material groove is opened on the top surface of the top material plate 51; a transmission component is provided on the fixed plate 41, which is used to drive the cylinder output end to extend and retract; when feeding the track pin, the pin is placed in the top material groove of the top material plate 51, and the pin on the feeding plate 42 is pushed to the limiting cylinder 2 by the push plate 43, which squeezes and triggers the transmission component. The transmission component introduces the squeezed gas into the cylinder inside the top material frame 5, so that the cylinder output end pushes the pin on the top material plate 51. Then the pin can be temporarily stored near the feeding plate 42 until the protrusion of the push plate 43 is reset. The temporarily stored pin falls into the V-shaped groove of the feeding plate 42 to wait for feeding, which plays the role of automatic feeding of the pin, thereby improving the chamfering efficiency of the track pin.

[0029] The transmission assembly includes an air box 6, a pressing rod 61, and an air guide pipe 62. The air box 6 is fixedly connected to the fixed plate 41. The pressing rod 61 is slidably connected to the air box 6 via an elastic element. The air guide pipe 62 is fixedly connected between the air box 6 and the cylinder. When the push plate 43 slides to push the pin, the push plate 43 can press the pressing rod 61. The elastic element contracts and is subjected to force. The pressing rod 61 simultaneously presses the gas in the air box 6. The gas is sent to the cylinder from the air guide pipe 62. The output end of the cylinder drives the top plate 51 to lift the pin. At this time, the top groove of the top plate 51 is higher than the surface of the fixed plate 41. The pin rolls down to the loading plate 42 to wait to be pushed to the chamfering position, which plays the role of driving the top plate 51.

[0030] The outer wall of the top material rack 5 is fixed with a storage plate 7; the top surface of the storage plate 7 is inclined; when multiple pins are automatically fed and chamfered, the storage plate 7 is fixed to one side of the top material rack 5 as a storage container, and multiple pins are arranged in sequence on the inclined top surface of the storage plate 7. In the initial state, one pin falls into the top material groove of the top material plate 51, and the remaining pins are arranged on the top surface of the storage plate 7. As the top material plate 51 slides up, it drives one pin to be fed. The outer wall of the top material plate 51 blocks the remaining pins until the top material plate 51 slides down and resets. Then, the next pin falls into the top material groove of the top material plate 51. This process is repeated to automatically feed multiple pins in sequence.

[0031] A guide groove 8 is provided on the fixed plate 41 near the top material frame 5; baffle plates 81 are fixed to both sides of the protrusion of the push plate 43; when the top material plate 51 slides up to feed material to the upper material plate 42, after the top material groove of the top material plate 51 is higher than the surface of the fixed plate 41, the pin in the top material groove rolls down along the inclined guide groove 8 to the outer wall of the baffle plate 81. After the protrusion of the push plate 43 is reset, the pin can fall into the V-shaped groove of the upper material plate 42 for temporary storage, which plays the role of guiding the pin down into the V-shaped groove of the upper material plate 42.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, a support base 9 is fixedly connected to the fixed base 11; an electric cylinder 91 is fixedly connected to the support base 9; a sliding frame 92 is fixedly connected to the output end of the electric cylinder 91; a limiting screw 93 is threadedly connected to the sliding frame 92; when the pin is pushed into the interior of the limiting cylinder 2, the output end of the electric cylinder 91 in the support base 9 drives the sliding frame 92 to slide down, so that the limiting screw 93 is pressed against one end of the limiting cylinder 2. The limiting screw 93 can limit the pushed pin, thereby ensuring that the pin can be centered inside the limiting cylinder 2. After the pin is centered and clamped, the output end of the electric cylinder 91 drives the limiting screw 93 to reset, which plays the role of correcting the position of the pin.

[0033] Working process: During the chamfering of both ends of the track pin, the machine body 1 serves as the main structure of the track chamfering equipment. First, a track pin is inserted into the through hole of the fixed base 11 and centered. Then, the sliding plates 13 on two opposing slide rails 12 slide close to both ends of the pin via electric sliders. After the cutters mounted on the cutter holders 14 come into contact with the outer wall of the pin, the pin is rapidly rotated by a power source, thus simultaneously chamfering both ends of the pin using the two cutter holders 14. This one-time forming of both ends of the pin replaces the traditional two-time chamfering process, reducing the tedious process of repeated feeding and improving the efficiency of chamfering both ends of the track pin. The double-blade chamfering method allows for one-time chamfering of both ends of the pin, eliminating the repeated positioning and edge-changing time of a single cutter. Simultaneous cutting by the double blades ensures that the chamfer dimensions at both ends are completely consistent, avoiding the cumulative errors of single-blade processing, providing good symmetry, reducing pin axis misalignment due to secondary clamping, and effectively controlling coaxiality. By setting four pairs of opposing cutter holders… The tool holders 14 are fixed with tools of the same type, and the two opposing tool holders 14 can be equipped with tools of the same type. This allows for flexible and quick switching of tools to perform chamfering work according to different chamfering requirements of the pin, improving the chamfering effect. Since the four tools are controlled independently, one tool is used to chamfer when only one end of the pin needs to be chamfered, thus allowing for flexible switching between chamfering at both ends and one end of the pin, improving the adaptability of the track preparation chamfering equipment. When chamfering the track pin, the pin is inserted into the limiting cylinder 2 in the through hole. After centering the pin, multiple second-order electric sliders drive the clamping blocks 23 to slide on the extension plate 22 close to the pin, so that both ends of the pin are clamped by the opposing clamping blocks 23. Then, the motor built into the fixing base 11 drives the gear 21 to rotate quickly to perform chamfering, which serves to fix the track pin. By opening V-shaped grooves on the opposite side of the two clamping blocks 23, the two clamping blocks 23 can adaptably clamp pins of different thicknesses with their V-shaped grooves after they come close together, improving the adaptability of limiting track pins of different thicknesses. When chamfering the track pins, waste chips are easily generated. Two inclined feed plates 3 are fixed on both sides of the fixed base 11 to collect the waste chips. After the waste chips fall, they can fall obliquely along the V-shaped groove on the top surface of the feed plate 3, which can clean up the waste chips from the chamfering of the pins. At the same time, after the pins are chamfered, the pins can also fall onto the feed plate 3 on one side of the fixed base 11 and be guided to be discharged along the V-shaped groove of one of the feed plates 3. When feeding track pins, multiple pins are placed sequentially on the feeding plate 42. Then, the third electric slider drives the push plate 43 to slide on the fixed plate 41 supported by the fixed frame 4. The protrusion of the push plate 43 pushes the pins on the feeding plate 42, clamping them inside the limiting cylinder 2, thus feeding the pins. After a track pin is chamfered, the protrusion of the push plate 43 pushes the pin to be processed on the feeding plate 42 to the limiting cylinder 2, allowing the processed pin to be ejected from the limiting cylinder 2, thus automating the unloading of the pins. When feeding track pins, relying on the... The V-shaped groove on the top surface of the material plate 42 limits the placement of the pin. The pin fits tightly against the surface of the V-shaped groove of the material plate 42, allowing the protrusion of the push plate 43 to fit against the surface of the V-shaped groove of the material plate 42 and stably push the pin, thereby improving the stability of feeding the track pin. When feeding the track pin, the pin is placed in the top groove of the top plate 51. During the process of pushing the pin on the material plate 42 to the limiting cylinder 2 by the push plate 43, the compression triggers the transmission component. The transmission component introduces the compressed gas into the cylinder inside the top frame 5, so that the output end of the cylinder pushes the pin on the top plate 51. Then the pin can approach the material plate. The pins are temporarily stored at 42 locations until the protrusion of the push plate 43 is reset. After this, the temporarily stored pins fall into the V-groove of the loading plate 42, awaiting loading. This automates the loading of the pins, thereby improving the chamfering efficiency of the track pins. When the push plate 43 slides and pushes the pin, it squeezes the extrusion rod 61. The elastic element contracts under pressure, and the extrusion rod 61 simultaneously squeezes the gas in the air box 6. The gas is sent from the air guide pipe 62 to the cylinder. The output end of the cylinder drives the top plate 51 to lift the pin. At this time, the top groove of the top plate 51 is higher than the surface of the fixed plate 41, and the pin rolls down to the loading plate 42, waiting to be pushed to the processing position for chamfering. It serves to drive the top plate 51; when multiple pins are automatically fed and chamfered, the storage plate 7 is fixed to one side of the top frame 5 as a storage container. Multiple pins are arranged in sequence on the inclined top surface of the storage plate 7. In the initial state, one pin falls into the top groove of the top plate 51, and the remaining pins are arranged on the top surface of the storage plate 7. As the top plate 51 slides up, it drives one pin to be fed. The outer wall of the top plate 51 blocks the remaining pins until the top plate 51 slides down and resets. Then, the next pin falls into the top groove of the top plate 51. This process is repeated to automatically feed multiple pins in sequence. When the top plate 51 slides up to feed the material to the feeding plate 42, after the top groove of the top plate 51 is higher than the surface of the fixed plate 41, the pin in the top groove rolls down along the surface of the inclined guide groove 8 to the outer wall of the baffle plate 81. After the protrusion of the push plate 43 is reset, the pin can fall into the V-groove of the feeding plate 42 for temporary storage, which plays the role of guiding the pin down to the V-groove of the feeding plate 42. When the pin is pushed into the limiting cylinder 2, the output end of the electric cylinder 91 in the support base 9 drives the sliding frame 92 to slide down, so that the limiting screw 93 is pressed against one end of the limiting cylinder 2. The limiting screw 93 can limit the pushed pin, thereby ensuring that the pin can be centered inside the limiting cylinder 2. After the pin is centered and clamped, the output end of the electric cylinder 91 drives the limiting screw 93 to reset, which plays the role of correcting the position of the pin.
