Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical devices, relates to a chain saw device, and in particular to a chain saw guide wheel installation machine. Background Art

[0002] A chain saw guide wheel installation machine is a mechanism for manufacturing and assembling chain saw guide wheels. A chain saw guide wheel is one of the components of a chain saw, usually located at the outer end of the guide plate, mostly circular, with grooves on the outer side to fit the chain links. It supports and guides the chain to run smoothly, ensuring cutting efficiency and safety.

[0003] In the prior art, manual feeding of each component of the guide wheel and pre-positioning before assembly are usually adopted, and manual intervention is also required for discharging the finished guide wheel after assembly.

[0004] The overall production efficiency is relatively low, and it is prone to failures, resulting in a low yield rate. On the other hand, in the production process, multiple processes rely on manual labor, leading to high production costs and the risk of accidents. Summary of the Invention

[0005] The object of the present invention is to solve the above problems and provide a chain saw guide wheel installation machine capable of automatic assembly.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A chain saw guide wheel installation machine includes a frame. A tooth plate support plate is provided on the frame. A through hole is provided on the tooth plate support plate. A circular plate support column fixedly arranged and not in contact with the through hole is provided in the through hole. The bottom of the circular plate support column is connected to the frame. A ball lifting sleeve is provided between the circular plate support column and the through hole. A ball lifting driving mechanism is provided at the bottom of the ball lifting sleeve. A ball inlet channel is provided on the side wall of the through hole. The outer end of the ball inlet channel is connected to a ball feeding mechanism. A circular plate feeding mechanism is provided on one side of the upper end of the through hole. A tooth plate feeding mechanism is also provided on the other side of the upper end of the through hole.

[0007] By separately providing a ball feeding mechanism, a circular plate feeding mechanism and a tooth plate feeding mechanism, the collaborative automatic feeding of each component of the guide wheel can be realized. By controlling the lifting of the ball lifting sleeve through the ball lifting driving mechanism, the accurately positioned components are assembled together, achieving the effect of fully automatic assembly of the guide wheel assembly.

[0008] In the above-mentioned chain saw guide wheel installation machine, the ball jacking drive mechanism includes a jacking lifting seat connected to the ball jacking sleeve. The jacking lifting seat is located inside or above the lifting hole of the machine frame. A support seat connected to the machine frame is provided at the bottom of the lifting hole. A guiding component is provided between the jacking lifting seat and the support seat, and a cam-type lifting drive component is also provided between the jacking lifting seat and the support seat. The setting of the guiding component can ensure that the jacking lifting seat moves strictly in the vertical direction, avoiding assembly errors caused by deviation. Moreover, by adopting the cam-type lifting drive component, the movement smoothness can be enhanced, and the influence of mechanical vibration on the assembly accuracy can be reduced.

[0009] The guiding component includes at least two guiding rods distributed circumferentially between the support seat and the jacking lifting seat. A guiding linear bearing and an auxiliary lowering spring are provided between the guiding rod and the support seat. The at least two guiding rods distributed circumferentially impose rigid constraints on the vertical movement of the jacking lifting seat from multiple directions, preventing the lifting seat from tilting or jamming, and ensuring that the axis of the ball jacking sleeve is always strictly aligned with the wafer support column.

[0010] In the above-mentioned chain saw guide wheel installation machine, the cam-type lifting drive component includes a cam slidably connected to the support seat. An inclined surface inclined to the bottom surface of the support seat is provided on the upper surface of the cam. At least one roller is provided on the inclined surface. The roller is connected to the jacking lifting seat through a roller seat. The cam is connected to a lifting linear drive that can drive the cam to move horizontally to drive the roller to lift. Through the rolling contact between the inclined surface of the cam and the roller, the horizontal linear movement of the lifting linear drive is directly converted into the vertical lifting movement of the jacking lifting seat. The rolling friction replaces the traditional sliding friction, which can extend the service life of the mechanism. At the same time, the slider rail unit accurately guides the horizontal movement of the cam, eliminating the influence of lateral deviation on the lifting trajectory, and ensuring the smoothness of the lifting action.

[0011] In the above-mentioned chain saw guide wheel installation machine, a rotation drive mechanism capable of driving the ball jacking sleeve to rotate is provided between the ball jacking sleeve and the jacking lifting seat. The rotation drive mechanism includes a driven gear fixed on the outer wall of the lower end of the ball jacking sleeve. A thrust bearing is provided between the ball jacking sleeve and the jacking lifting seat. The driven gear is connected to a driving gear, and the driving gear is connected to a rotation driver. The design of the meshing transmission between the driven gear and the driving gear provides high-precision and high-rigidity power transmission, can accurately control the rotation angle of the ball jacking sleeve, and meets the requirements for angle positioning in precision assembly. Moreover, through the setting of the thrust bearing, the thrust bearing bears the axial load and isolates the rotational freedom, enabling the ball jacking sleeve to rotate independently during the lifting process, avoiding interference between the two movements, and ensuring the independent control and coordinated execution of the lifting and rotation actions.

[0012] The driven gear is connected to the ball lifting sleeve through a bearing guide sleeve. The lower end of the driven gear abuts against the convex ring of the bearing guide sleeve and is fixed by several bolts. The lower end of the ball lifting sleeve is sleeved on the bearing guide sleeve and fixed by several radial bolts. A first linear bearing is provided between the bearing guide sleeve and the wafer support column, and a thrust bearing is arranged between the bearing guide sleeve and the bearing step of the lifting seat.

[0013] The wafer support column includes an upper head and a support rod. The lower end of the support rod is detachably fixed to the support.

[0014] In the above-mentioned chain saw guide wheel installation machine, the wafer feeding mechanism includes a wafer support plate located on one side above the tooth plate support plate. A wafer blanking hole coaxial with the through hole is provided on the wafer support plate. A wafer feeding cylinder with both ends open is provided on one side of the wafer blanking hole. A radial feeding groove is provided between the lower end of the wafer feeding cylinder and the upper surface of the wafer support plate. A wafer pushing plate is arranged in the radial feeding groove, and the wafer pushing plate is connected to a wafer pushing plate driving assembly. By setting the wafer blanking hole coaxially with the through hole, it ensures that the path of the wafer from the feeding mechanism to the assembly station is strictly aligned. This design can eliminate the cumulative error caused by multiple transfers, enabling the wafer to accurately fall into the predetermined position in the through hole, providing guarantee for subsequent precise assembly.

[0015] In the above-mentioned chain saw guide wheel installation machine, an elastic limiting structure capable of restricting the falling of the wafer and falling when the wafer is subjected to an axial force is provided on the wafer blanking hole. A wafer accommodating gap is left between the elastic limiting structure and the upper end of the wafer blanking hole; a wafer pressing rod is also provided at the upper end of the wafer blanking hole, and the wafer pressing rod is connected to a wafer pressing rod driving assembly. Through the setting of the elastic limiting structure, the wafer is stably restricted in the blanking hole without external force, avoiding accidental falling caused by vibration or gravity. And when it is necessary to release the wafer during the assembly process, such as when the pressing rod applies an axial force, the elastic limiting structure can quickly release the constraint, ensuring that the wafer accurately falls only under controlled conditions, further improving the accuracy of the overall assembly process.

[0016] The wafer pushing plate is provided with a semi-circular wafer limiting hole at one end of the wafer blanking hole; the wafer feeding cylinder is detachably fixed to the wafer support plate.

[0017] The wafer pushing plate driving assembly includes a first linear driver arranged at the end of the wafer pushing plate away from the wafer blanking hole. The first linear driver is connected to the wafer support plate through a first slider rail structure.

[0018] The first slider rail structure and the first linear driver are located at the bottom of the wafer blanking hole. Two first strip-shaped grooves are provided on the wafer support plate on both sides of the first slider rail structure respectively. A first connecting rod is arranged in the first strip-shaped groove. The upper end of the first connecting rod is connected to the wafer pushing plate, and the lower end is connected to the slider of the first slider rail structure.

[0019] In the above-mentioned chain saw guide wheel installation machine, the elastic limit structure includes at least three radial elastic units distributed along the circumferential direction and capable of radially expanding and contracting near the upper end in the wafer blanking hole; the radial elastic unit includes a limit bead, a blanking sleeve is arranged in the wafer blanking hole, and the blanking sleeve is provided with limit bead radial moving holes equal in number to the limit beads, and the inner diameter of the limit bead radial moving hole is smaller than the outer diameter of the limit bead. An elastic part accommodating hole is provided on the inner wall of the wafer blanking hole, and an elastic part is arranged between the limit bead and the elastic part accommodating hole; the upper end of the blanking sleeve extends beyond the upper end of the wafer blanking hole, and a wafer radial inlet is arranged on one side of the blanking sleeve located in the radial feeding groove.

[0020] The design that the upper end of the blanking sleeve extends beyond the upper end of the wafer blanking hole and is provided with a wafer radial inlet can prevent the wafer from not accurately falling into the wafer blanking hole due to the inertia of radial feeding. Moreover, through at least three radial elastic units distributed along the circumference, the edge of the wafer is synchronously clamped at multiple points, avoiding tilting or offset caused by unilateral pressure. The limit beads radially expand and contract under the action of the elastic part, evenly contacting the outer edge of the wafer, ensuring that the wafer is centered in the blanking hole and providing a stable pre-positioning support for subsequent assembly.

[0021] The wafer pressing rod driving assembly includes a lifting slider rail fixed on one side of the upper end of the wafer blanking hole. The slider of the lifting slider rail is connected to the L-shaped wafer pressing rod fixing plate at the upper end of the wafer pressing rod, and the wafer pressing rod fixing plate is connected to the pressing rod linear driver.

[0022] The rail of the lifting slider rail is fixed on the frame, the wafer support plate is detachably fixed on the frame through a plurality of support columns, and buffers are respectively arranged at the upper and lower ends of the buffer impact body on the side wall of the wafer pressing rod fixing plate.

[0023] In the above-mentioned chain saw guide wheel installation machine, the chip feeding mechanism includes a chip feeding cylinder with two open ends arranged on the side far from the through hole. A sheet-shaped chip radial feeding channel is arranged between the lower end of the chip feeding cylinder and the upper surface of the chip support plate. A chip push plate is arranged in the chip radial feeding channel, and the chip push plate is connected to the chip push plate driving assembly. A chip limiting assembly capable of restricting the rotation of the chip is arranged in the chip feeding cylinder. Through the arrangement of the chip limiting assembly, the rotation of the chip in the feeding cylinder is restricted, ensuring that the tooth shape orientation is always consistent with the requirements of the assembly station. This directional constraint prevents the chip from rotating due to vibration or friction during transportation, ensuring the precise meshing of the chip with the ball and the wafer during subsequent assembly.

[0024] The chip push plate driving assembly includes a second linear driver arranged at the end of the chip push plate far from the through hole. The second linear driver is connected to the chip support plate through a second slider rail structure.

[0025] The second slider rail structure and the second linear driver are located at the bottom of the through hole. Two second strip-shaped grooves are provided on the chip support plate, which are respectively located on both sides of the second slider rail structure. A second connecting rod is provided in the second strip-shaped groove. The upper end of the second connecting rod is connected to the chip push plate, and the lower end is connected to the slider of the second slider rail structure.

[0026] The chip limiting component includes at least two chip limiting columns distributed along the circumferential direction of the chip feeding cylinder. The chip limiting columns are fixed on the inner wall of the chip feeding cylinder.

[0027] The front end of the chip push plate is provided with a chip anti-displacement structure that can prevent the chip from displacing when it is pushed out of the radial feeding channel of the tooth body.

[0028] The chip anti-displacement structure includes a chip slot provided at the front end of the chip push plate.

[0029] The chip slot is semicircular or adapted to the chip tooth body.

[0030] The lower end of the chip feeding cylinder is provided with an annular chip feeding cylinder base, and the bottom of the chip feeding cylinder base is provided with a radial feeding channel for the tooth body.

[0031] The chip feeding cylinder and the chip feeding cylinder base are integrated, and the chip feeding cylinder base and the chip support plate are fixed by a plurality of bolts.

[0032] The second linear driver is a cylinder, an oil cylinder or an electric cylinder. The tail of the second linear driver is connected to the rear end of the chip support plate, and the output end of the second linear driver is connected to the slider of the second slider rail structure.

[0033] In the above-mentioned chain saw guide wheel installation machine, an L-shaped assembly ejector plate is provided on the chip support plate and between the wafer feeding mechanism and the chip feeding mechanism. The rear end of the assembly ejector plate is connected to the ejecting linear driver, and the ejecting linear driver is connected to the frame through the ejecting linear driver bracket. The control of the ejecting linear driver is linked with the action timing sequence of the wafer and chip feeding mechanisms. After the ball and the chip are assembled, the ejector plate immediately ejects the finished guide wheel from the working station, vacating the assembly area to receive the next set of parts, realizing seamless connection of the production beat, and thus improving the production cycle efficiency of the overall equipment.

[0034] The assembly ejector plate is slidably connected to the chip support plate or the bottom surface of the assembly ejector plate is close to the top surface of the chip support plate and does not touch, and there is a movable gap between the assembly ejector plate and the chip support plate.

[0035] In the above-mentioned chain saw guide wheel installation machine, the ball feeding mechanism includes an S-shaped ball feeding pipe. The lower end of the ball feeding pipe is communicated with the outer end of the ball inlet channel. The S-shaped ball feeding pipe is provided with ball feeding grooves that are distributed along its length direction and have a convex cross-section. The ball feeding grooves with a convex cross-section limit the balls at the center of the grooves through their cross-sectional design, preventing the balls from laterally shifting or deviating from the predetermined path during transportation, and can meet the precise guiding requirements in high-speed feeding scenarios.

[0036] Compared with the existing technology, the advantages of this chain saw guide wheel installation machine are as follows: 1. The feeding mechanisms of the wafer, toothed piece, and ball are linked and controlled with the assembly ejection mechanism, and multiple workstations cooperate to operate, with high production efficiency. 2. The stacked design of the feeding cylinder and the S-shaped ball feeding pipe supports batch preloading, eliminates the need for frequent replenishment of materials, and has a long continuous production time. 3. The fully automated process eliminates the risk of manual contact and has a low probability of accidents. Brief Description of the Drawings

[0076] The chip clamping groove 242 is semi-circular or adapted to the tooth body of the chip 26.

[0077] The lower end of the chip feeding cylinder 22 is provided with an annular chip feeding cylinder base 223. The bottom of the chip feeding cylinder base 223 is provided with a radial feeding channel 23 of the tooth body.

[0078] The chip feeding cylinder 22 and the chip feeding cylinder base 223 are integrated. The chip feeding cylinder base 223 and the chip support plate 21 are fixed by a plurality of bolts.

[0079] The second linear driver 251 is a cylinder, an oil cylinder or an electric cylinder. The tail of the second linear driver 251 is connected to the rear end of the chip support plate 21, and the output end of the second linear driver 251 is connected to the slider of the second slider rail structure 252.

[0080] More specifically, an L-shaped assembly ejecting plate 51 is provided on the chip support plate 21 and between the wafer feeding mechanism 3 and the chip feeding mechanism 2. The rear end of the assembly ejecting plate 51 is connected to the ejecting linear driver 5. The ejecting linear driver 5 is connected to the frame 1 through an ejecting linear driver bracket 15.

[0081] In this embodiment, the assembly ejecting plate 51 is slidably connected to the chip support plate 21 or the bottom surface of the assembly ejecting plate 51 is close to the top surface of the chip support plate 21 and does not contact, leaving a movable gap between the assembly ejecting plate 51 and the chip support plate 21.

[0082] More specifically, the ball feeding mechanism 6 includes an S-shaped ball feeding tube 61. The lower end of the ball feeding tube 61 communicates with the outer end of the ball inlet channel 212. The S-shaped ball feeding tube 61 is provided with ball feeding grooves 62 distributed along its length direction and having a convex cross-section.

[0083] The working principle of this embodiment is as follows. A number of tooth pieces 25 are arranged in the tooth piece feeding cylinder 22. When the second linear driver 251 pulls the tooth piece push plate 24 backward through the second slider rail structure 252, the lowermost tooth piece 26 falls into the radial feeding channel 23 through the position-limiting adjustment of the tooth piece position-limiting post 222. Subsequently, the tooth piece push plate 24 extends forward, and the front tooth piece card slot 242 pushes the tooth piece 26 to the designated position.

[0084] A number of circular wafers are arranged in the circular wafer feeding cylinder 32. When the first linear driver 351 pulls the circular wafer push plate 34 backward through the first slider rail structure 352, the lowermost circular wafer falls into the radial feeding groove 33. Subsequently, the circular wafer push plate 34 extends forward, and the front circular wafer limiting semi-hole 341 pushes the circular wafer into the circular wafer accommodating gap 313 in the circular wafer blanking hole 311.

[0085] The balls move along the ball feeding grooves 62 of the ball feeding tube 61 from the ball feeding mechanism 6 until they enter the through hole 211 from the ball inlet channel 212, and finally stop at the corresponding positions of the ball lifting sleeve 41.

[0086] At this time, the circular wafer pressing rod 36 presses down. Under the pressure of the circular wafer pressing rod 51, the radial ejector 133 retracts into the radial hole 112. The rotary driver 437 drives the driving gear 432 and the driven gear 431 to drive the ball lifting sleeve 41 to rotate. At the same time, the lifting linear driver 455 drives the cam 551 to move along the slider rail unit 456, and drives the lifting and lowering seat 42 to rise through the cooperation of the inclined surface 452 and the roller 453, realizing the assembly.

[0087] After the assembly is completed, the ejecting linear driver 5 drives the assembly ejecting plate 51 to extend forward to eject the assembled guide wheel, and then the assembly ejecting plate 51 retracts backward.

[0088] The pressing rod linear driver 372 drives the circular wafer pressing rod 36 to lift through the lifting slider rail 371. The first linear driver 351 pulls the circular wafer push plate 34 backward through the first slider rail structure 352. The second linear driver 251 pulls the tooth piece push plate 24 backward through the second slider rail structure 252. The lifting and lowering seat 42 descends, and the balls enter again from the ball feeding mechanism 6 along the ball inlet channel 212 for the next cycle of assembly.
