Description

Technical Field

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

[0002] Chain saw guide wheel installation machine is a mechanism used to produce and transfer chain saw guide wheels. Chain saw guide wheels are one of the components of chainsaws. They are usually located at the outer end of the guide plate. They are mostly round and have grooves on the outside to fit the chain links. They support and guide the chain to run smoothly, ensuring cutting efficiency and safety.

[0003] In the prior art, manual loading of the various components of the guide wheel and pre-positioning before assembly are usually performed, and the guide wheel finished product after assembly also requires manual intervention for unloading.

[0004] The overall production efficiency is low and prone to failure, resulting in low yield rate. On the other hand, in the production process, many processes rely on manual labor, resulting in high production costs and the risk of accidents. Summary of the invention

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

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

[0007] Through the separately arranged ball feeding mechanism, disc feeding mechanism and gear feeding mechanism, the coordinated automatic feeding of the guide wheel components can be realized, and the lifting and lowering of the ball lifting sleeve is controlled by the ball lifting drive mechanism to assemble the precisely positioned components together, thus 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 lifting drive mechanism includes a lifting and lowering seat connected to the ball lifting sleeve, the lifting and lowering seat is located in the lifting hole of the frame or above the lifting hole, a support connected to the frame is provided at the bottom of the lifting hole, a guide component is provided between the lifting and lowering seat and the support, and a cam-type lifting drive component is also provided between the lifting and lowering seat and the support. The provision of the guide component can ensure that the lifting and lowering seat moves strictly in the vertical direction to avoid assembly errors caused by offset. In addition, the use of a cam-type lifting drive component can enhance the smoothness of movement and reduce the influence of mechanical vibration on assembly accuracy.

[0009] The guide assembly includes at least two circumferentially distributed guide rods arranged between the support and the lifting and lowering seat, and a guide linear bearing and an auxiliary lowering spring are arranged between the guide rod and the support. At least two circumferentially distributed guide rods impose rigid constraints on the vertical movement of the lifting and lowering seat from multiple directions, preventing the lifting seat from tilting or getting stuck, and ensuring that the axis of the ball lifting sleeve is always strictly aligned with the disc support column.

[0010] In the above-mentioned chain saw guide wheel installation machine, the cam-type lifting drive assembly includes a cam slidably connected to the support, the upper surface of the cam is provided with an inclined surface inclined to the bottom surface of the support, at least one roller is provided on the inclined surface, the roller is connected to the top lifting seat through the roller seat, and the cam is connected to the lifting linear driver that can drive the cam to move laterally and drive the roller to lift. Through the rolling contact between the inclined surface of the cam and the roller, the lateral linear motion of the lifting linear driver is directly converted into the vertical lifting motion of the top lifting seat, and 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 lateral movement of the cam, eliminates the influence of lateral offset on the lifting trajectory, and can ensure the smoothness of the lifting action.

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

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

[0013] The disc support column comprises an upper head and a support rod, and 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 disc feeding mechanism includes a disc support plate located on one side above the tooth support plate, a disc blanking hole coaxially arranged with the through hole is provided on the disc support plate, a disc feeding cylinder with two ends open is provided on one side of the disc blanking hole, a radial feeding groove is provided between the lower end of the disc feeding cylinder and the upper surface of the disc support plate, a disc push plate is provided in the radial feeding groove, and the disc push plate is connected to the disc push plate driving assembly. The disc blanking hole and the through hole are coaxially arranged to ensure that the path of the disc from the feeding mechanism to the assembly station is strictly aligned. This design can eliminate the cumulative error caused by multiple transfers, so that the disc can maintain the predetermined position accurately falling into the through hole, providing a guarantee for subsequent precise assembly.

[0015] In the above-mentioned chain saw guide wheel installation machine, an elastic limiting structure is provided on the disc blanking hole, which can limit the disc from falling and can fall when the disc is subjected to axial force, and a disc accommodating gap is left between the elastic limiting structure and the upper end of the disc blanking hole; a disc pressure rod is also provided at the upper end of the disc blanking hole, and the disc pressure rod is connected to the disc pressure rod driving assembly. Through the setting of the elastic limiting structure, the disc is stably restricted in the blanking hole when there is no external force, avoiding accidental falling due to vibration or gravity. When the disc needs to be released during the assembly process, such as when the pressure rod applies axial force, the elastic limiting structure can quickly release the constraint to ensure that the disc only falls accurately under controlled conditions, further improving the accuracy of the overall assembly process.

[0016] A disc limiting half hole is arranged on one end of the disc pushing plate located at the disc blanking hole; the disc feeding cylinder and the disc supporting plate are detachably fixed.

[0017] The wafer push plate driving assembly comprises a first linear driver arranged on one end of the wafer push plate away from the wafer blanking hole, and 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 drive are located at the bottom of the wafer blanking hole. Two first strip grooves are opened on the wafer support plate and are respectively located on both sides of the first slider rail structure. A first connecting rod is arranged in the first strip groove. The upper end of the first connecting rod is connected to the wafer push 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 limiting structure includes at least three radial elastic units distributed in the circumferential direction and capable of radial expansion and contraction thereof, which are arranged in the blanking hole of the disc and close to the upper end; the radial elastic unit includes a limiting bead, a blanking sleeve is arranged in the blanking hole of the disc, and the blanking sleeve is provided with radial movable holes of limiting beads, the number of which is equal to the limiting beads, and the inner diameter of the radial movable holes of the limiting beads is smaller than the outer diameter of the limiting beads, an elastic part accommodating hole is arranged on the inner wall of the blanking hole of the disc, and an elastic part is arranged between the limiting bead and the elastic part accommodating hole; the upper end height of the blanking sleeve exceeds the upper end of the blanking hole of the disc, and a radial inlet for the disc is arranged on one side of the blanking sleeve located on the radial feeding trough.

[0020] The upper end of the blanking sleeve is higher than the upper end of the blanking hole for the disc, and the design of a radial inlet for the disc can prevent the disc from not falling accurately into the blanking hole due to the inertia of radial feeding. In addition, through at least three radial elastic units distributed along the circumference, the edge of the disc is clamped synchronously at multiple points to avoid tilting or offset caused by unilateral pressure. The limit bead expands and contracts radially under the action of the elastic member, evenly contacts the outer edge of the disc, ensures that the disc is centered in the blanking hole, and provides stable pre-positioning support for subsequent assembly.

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

[0022] The slide rails of the lifting slider are fixed on the frame, the disc 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 of the side wall of the disc pressure rod fixing plate.

[0023] In the above-mentioned chain saw guide wheel installation machine, the gear feeding mechanism includes a gear feeding cylinder with openings at both ends arranged on the side away from the through hole, a radial feeding channel for the tooth body in the form of a sheet is provided between the lower end of the gear feeding cylinder and the upper surface of the gear support plate, a gear push plate is provided in the radial feeding channel for the tooth body, and the gear push plate is connected to the gear push plate driving assembly, and a gear limiting assembly capable of limiting the rotation of the gear is provided in the gear feeding cylinder. Through the provision of the gear limiting assembly, the gear is restricted from rotating in the feeding cylinder, ensuring that the orientation of its tooth shape is always consistent with the requirements of the assembly station. This directional constraint prevents the gear from rotating due to vibration or friction during the conveying process, and ensures the precise engagement of the gear with the ball and disc during subsequent assembly.

[0024] The gear push plate driving assembly comprises a second linear driver arranged on one end of the gear push plate away from the through hole, and the second linear driver is connected to the gear support plate through a second slider rail structure.

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

[0026] The gear piece limiting assembly comprises at least two gear piece limiting columns which are arranged in the gear piece feeding tube and distributed along the circumference thereof, and the gear piece limiting columns are fixed on the inner wall of the gear piece feeding tube.

[0027] A tooth piece anti-dislocation structure is provided at the front end of the tooth piece push plate, which can prevent the tooth piece from being displaced when being pushed out of the radial feeding channel of the tooth body.

[0028] The tooth plate anti-dislocation structure comprises a tooth plate clamping groove arranged at the front end of the tooth plate push plate.

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

[0030] The lower end of the gear feeding barrel is provided with an annular gear feeding barrel base, and the bottom of the gear feeding barrel base is provided with a gear body radial feeding channel.

[0031] The gear feeding barrel is connected with the gear feeding barrel base as a whole, and the gear feeding barrel base and the gear supporting plate are fixed by a plurality of bolts.

[0032] The second linear drive is an air cylinder, an oil cylinder or an electric cylinder. The tail of the second linear drive is connected to the rear end of the gear support plate, and the output end of the second linear drive 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 tooth support plate and between the disc feeding mechanism and the tooth feeding mechanism. The rear end of the assembly ejector plate is connected to the ejector linear drive, and the ejector linear drive is connected to the frame through the ejector linear drive bracket. The control of the ejector linear drive is linked to the action sequence of the disc and tooth feeding mechanism. After the assembly of the ball and the tooth is completed, the ejector plate immediately pushes the finished guide wheel out of the workstation, vacating the assembly area to receive the next set of parts, achieving seamless connection of the production rhythm, and thus improving the production cycle efficiency of the overall equipment.

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

[0035] In the above-mentioned chain saw guide wheel installation machine, the ball feeding mechanism includes an S-shaped ball feeding tube, the lower end of which is connected to the outer end of the ball entry channel, and the S-shaped ball feeding tube is provided with a ball feeding groove distributed along its length and having a convex cross-section. The convex-shaped ball feeding groove restricts the ball in the center of the groove through its cross-sectional design, preventing the ball from lateral displacement or deviating from the predetermined path during the conveying process, and can meet the precise guidance requirements in high-speed feeding scenarios.

[0036] Compared with the existing technology, the advantages of this chain saw guide wheel installation machine are: 1. The feeding mechanism of the disc, gear and ball is linked with the assembly ejection mechanism, and the multi-station collaborative operation has high production efficiency. 2. The stacking design of the feeding cylinder and the S-shaped ball feeding tube supports batch pre-loading, without frequent refilling, and 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] An annular gear feeding barrel base 223 is provided at the lower end of the gear feeding barrel 22 , and a gear radial feeding channel 23 is provided at the bottom of the gear feeding barrel base 223 .

[0077] The gear feeding cylinder 22 is connected to the gear feeding cylinder base 223 as a whole, and the gear feeding cylinder base 223 is fixed to the gear supporting plate 21 by a plurality of bolts.

[0078] The second linear driver 251 is a pneumatic cylinder, an oil cylinder or an electric cylinder. The tail of the second linear driver 251 is connected to the rear end of the gear 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 .

[0082] The working principle of this embodiment is that a plurality of teeth 25 are arranged in the tooth feeding barrel 22. When the second linear drive 251 pulls the tooth push plate 24 backward through the second slider rail structure 252, the tooth 26 at the bottom is adjusted by the limit of the tooth limit column 222 and falls into the radial feeding channel 23. Then the tooth push plate 24 extends forward, and the tooth slot 242 at the front end pushes the tooth 26 to the specified position.

[0083] A number of discs are arranged in the disc feeding cylinder 32.

At the same time, the lifting linear driver 455 drives the cam 551 to move along the slider rail unit 456, and the lifting and lifting seat 42 is driven to rise through the cooperation of the inclined surface 452 and the roller 453 to realize assembly.

[0086] After the assembly is completed, the ejection linear drive 5 drives the assembly ejection plate 51 to extend forward to move the assembled guide wheel out, and then the assembly ejection plate 51 is retracted backward.

[0087] The pressure rod linear driver 372 drives the disc pressure rod 36 to lift up through the lifting slider rail 371, and the first linear driver 351 pulls the disc push plate 34 backward through the first slider rail structure 352; the second linear driver 251 pulls the tooth push plate 24 backward through the second slider rail structure 252; the lifting and lifting seat 42 descends, and the ball enters from the ball feeding mechanism 6 along the ball entry channel 212 again to carry out the next cycle of assembly.
