Description

Technical Field

[0001] This utility model relates to the field of grinding machine feeding technology, specifically to an auxiliary feeding device for a double-sided grinding machine. Background Technology

[0002] Double-sided grinding machines can simultaneously process both end faces of the inner and outer rings of a bearing, doubling the processing efficiency and effectively improving the production efficiency of the workshop.

[0003] Publication No. CN220637434U discloses a workpiece conveying mechanism for a grinding machine. This device, through the arrangement of an inclined conveying track, a side conveying component, and a bottom conveying component, allows the finished workpiece to be placed on top of the conveying track. The workpiece slides inwards along the inclination angle of the conveying track. The bottom of the workpiece moves via the bottom conveying component, and one side moves via the side conveying component, ensuring normal workpiece conveying. Simultaneously, the inclination angle provides friction to the workpiece, allowing for more stable movement within the conveying track and preventing it from falling. The friction also slows the workpiece during movement, facilitating retrieval by the operator at the other end, thus improving processing convenience and efficiency. However, this patent still has the following problems in practical use:

[0004] This device, with its inclined conveyor track, side conveyor components, and bottom conveyor components, ensures the normal transport of workpieces. The inclined angle also provides friction to the workpieces, allowing them to move more stably within the conveyor track and preventing them from falling. However, the device lacks height adjustment, which makes it inconvenient for operators to load or unload materials onto or off the grinding machine, significantly reducing the device's flexibility and causing inconvenience for users.

[0005] A double-sided grinding machine auxiliary feeding device is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary feeding device for a double-sided grinding machine, which solves the problem mentioned in the background art. The current device uses an inclined conveying track, a side conveying component, and a bottom conveying component to ensure normal workpiece conveying. At the same time, the inclined angle can give the workpiece a certain friction force and make it move more stably inside the conveying track, avoiding the workpiece falling. However, this device does not have a height adjustment function, which makes it inconvenient for operators to load and unload the grinding machine at higher or lower heights, greatly reducing the flexibility of the device during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-sided grinding machine auxiliary feeding device, including a base, a shell is provided on the top of the base, and rotating rollers are symmetrically rotatably connected to both ends of the shell, and a conveyor belt is sleeved between the outer sides of the rotating rollers, and a servo motor is fixedly installed at one end of the rotating rollers; a lifting mechanism is provided between the top of the base and the bottom of the shell, and limit components are symmetrically provided on both sides of the base;

[0008] The lifting mechanism includes a box fixedly installed on the top of the base, and a sliding box symmetrically fixedly connected to the top of the base. The sliding box has a mounting groove inside its lower part. A rotating rod is rotatably connected between the box, the sliding box, and the mounting groove. A worm gear is rotatably connected between the box and the base. A worm wheel is fixedly installed on the outer center of the rotating rod. A screw is rotatably connected between the sliding box and the mounting groove. A lifting rod is slidably connected to the upper part of the sliding box. The internal threaded groove of the lifting rod is threadedly connected to the outer surface of the screw. First conical teeth are fixedly installed on the outer surfaces of both ends of the rotating rod, and second conical teeth are fixedly installed on the bottom of the screw. A forward and reverse motor is fixedly installed on the top of the worm gear. A support platform is fixedly connected to one end of the housing, and the top of the lifting rod is fixedly connected to the bottom of the housing.

[0009] Preferably, the top of each base is symmetrically fixedly connected with a support tube, and the bottom of each housing is symmetrically fixedly connected with a support rod. The bottom of the support rod passes through the support tube and is slidably connected to the support tube. A fixing groove is provided on one side of each support rod, and a fixing knob is threadedly connected between the support tube and the fixing groove.

[0010] Preferably, the limiting component includes a support plate, which is symmetrically and fixedly connected to both sides of the base. A fixing plate is fixedly connected to the top side of the support plate, and a threaded rod is threadedly connected to the inside of the fixing plate. A pressing plate is rotatably connected to the bottom of the threaded rod, and a rubber pad is fixedly installed at the bottom of the pressing plate. A guide rod is symmetrically and fixedly connected to the top of the pressing plate, and the top of the guide rod passes through the fixing plate and is slidably connected to the fixing plate. A stop block is fixedly connected to the top of the guide rod.

[0011] Preferably, the outside of the rotating rod is engaged with a limiting block, and the bottom of the limiting block is fixedly connected to the base.

[0012] Preferably, a rotating block is fixedly connected to the top of the threaded rod.

[0013] Preferably, the worm and the worm wheel are meshed together.

[0014] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This auxiliary feeding device for a double-sided grinding machine specifically includes the following: The operation of a forward and reverse motor drives the rotation of a worm gear, which in turn drives the rotation of a worm wheel. The rotation of the rotating rod drives the rotation of two sets of first conical teeth, which in turn drives the rotation of second conical teeth. The rotation of the second conical teeth drives the rotation of a screw, which in turn causes a lifting rod to slide up and down inside the sliding box. This allows the conveyor belt to flexibly change its conveying direction according to the actual layout of the double-sided grinding machine and the material feeding requirements, accurately conveying materials to different positions around the grinding machine. This effectively addresses the complex and ever-changing space constraints of the production site, achieving double-sided grinding... The flexible loading and unloading of materials on the bed reduces the distance and difficulty of manual handling, significantly reducing labor intensity. By having the operator rotate the threaded rod inside the fixed plate, the rotation of the threaded rod causes the extrusion plate to move up and down against the support plate. At this time, the movement of the extrusion plate causes the guide rod to slide inside the fixed plate. At this time, the stop block limits the guide rod, and the rubber pad is used to press against the ground, thereby achieving the effect of quickly fixing the limiting base. This effectively increases the contact area between the bottom of the base and the ground, and the high friction of the rubber pad ensures stable placement of the equipment, avoiding the phenomenon of equipment displacement caused by external force collisions, and greatly improving the stability of the device during use.

[0016] 1. A servo motor drives the rotating roller to rotate. The interaction between the rotating roller and the conveyor belt enables the conveyor belt to transport materials. The conveyor belt transports the materials to the top of the support platform. The operation of the forward and reverse motors drives the worm gear to rotate, which in turn drives the worm wheel. The worm wheel then drives the rotating rod, which in turn drives the two sets of first conical teeth. The first conical teeth drive the second conical teeth, which in turn drives the screw. Due to the fit between the screw's external surface and the internal threaded groove of the lifting rod, the screw's rotation causes the lifting rod to slide up and down inside the sliding box. The movement of the lifting rod causes the housing to move longitudinally... The conveyor belt can be moved to flexibly change its direction according to the actual layout of the double-sided grinder and the material feeding requirements, accurately delivering materials to different positions around the grinder. This effectively copes with the complex and ever-changing space constraints of the production site, enabling flexible loading and unloading of materials for the double-sided grinder. It reduces the distance and difficulty of manual handling and significantly reduces the intensity of manual labor. When the shell moves up and down, it causes the support rod to slide inside the support tube. At this time, the operator fixes the fixing knob with the fixing groove through the thread, which enables the shell to be quickly raised and lowered for support. This effectively reduces the phenomenon of shell displacement and shaking caused by external force collisions, and improves the stability of the equipment during use.

[0017] 2. By rotating the threaded rod inside the fixed plate, the rotation of the threaded rod causes the extrusion plate to move up and down against the support plate. At this time, the movement of the extrusion plate causes the guide rod to slide inside the fixed plate. At this time, the stop block limits the guide rod. When the extrusion plate moves down, the rubber pad presses against the ground, thereby achieving the effect of quickly fixing the limiting base. This effectively increases the contact area between the bottom of the base and the ground. Furthermore, the high friction of the rubber pad ensures stable placement of the equipment, avoiding the phenomenon of equipment displacement caused by external force collisions, and greatly improving the stability of the device during use.

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.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a double-sided grinding machine auxiliary feeding device, including a base 1, a housing 101 on the top of the base 1, and rotating rollers 102 symmetrically rotatably connected to both ends of the housing 101, and a conveyor belt 103 sleeved between the outer sides of the rotating rollers 102, and a servo motor 104 fixedly installed at one end of the rotating rollers 102; a lifting mechanism 2 is provided between the top of the base 1 and the bottom of the housing 101, and limit components 3 are symmetrically provided on both sides of the base 1;

[0026] The lifting mechanism 2 includes a box 201 fixedly installed on the top of the base 1, and a sliding box 202 symmetrically fixedly connected to the top of the base 1. The lower interior of the sliding box 202 has a mounting groove 203. A rotating rod 204 is rotatably connected between the box 201, the sliding box 202, and the mounting groove 203. A worm gear 205 is rotatably connected between the box 201 and the base 1. A worm wheel 206 is fixedly installed on the outer center of the rotating rod 204, and the worm gear 205 and the worm wheel 206 are meshed together. A screw 207 is rotatably connected between the sliding box 202 and the mounting groove 203. A lifting rod 2071 is slidably connected to the upper interior of the sliding box 202, and the internal thread groove of the lifting rod 2071 is threadedly connected to the external thread of the screw 207. Both ends of the 04 are fixedly installed with first conical teeth 208, and the bottom of the screw 207 is fixedly installed with second conical teeth 209.

One end of the housing 101 is fixedly connected with a support platform 211, and the top of the lifting rod 2071 is fixedly connected with the bottom of the housing 101. Thus, the conveyor belt 103 can flexibly change the conveying direction according to the actual layout of the double-sided grinding machine and the material feeding requirements, accurately conveying the material to different positions around the grinding machine. This effectively copes with the complex and ever-changing space constraints of the production site, realizes flexible loading or unloading of the double-sided grinding machine, reduces the distance and difficulty of manual handling, and significantly reduces the intensity of human labor.

[0027] Support tubes 212 are symmetrically fixedly connected to the top of the base 1, and support rods 213 are symmetrically fixedly connected to the bottom of the housing 101. The bottom of the support rods 213 passes through the support tubes 212 and is slidably connected to the support tubes 212. A fixing groove 214 is provided on one side of each support rod 213, and a fixing knob 215 is threaded between the support tubes 212 and the fixing grooves 214. This enables the housing 101 to be quickly raised and lowered and supported, thereby effectively reducing the phenomenon of the housing 101 shifting and shaking due to external force collisions and improving the stability of the equipment during use. The outside of the rotating rod 204 is engaged with a limit block 216, and the bottom of the limit block 216 is fixedly connected to the base 1. Through the design of the limit block 216, the rotation of the rotating rod 204 can be made more stable.

[0028] The limiting component 3 includes a support plate 301, which is symmetrically fixedly connected to both sides of the base 1. A fixing plate 302 is fixedly connected to the top side of the support plate 301. A threaded rod 303 is threadedly connected to the inside of the fixing plate 302. A pressing plate 304 is rotatably connected to the bottom of the threaded rod 303. A rubber pad 305 is fixedly installed at the bottom of the pressing plate 304. Guide rods 306 are symmetrically fixedly connected to the top of the pressing plate 304. The top of the guide rods 306 passes through the fixing plate 302 and is slidably connected to the fixing plate 302. Furthermore, a stop block 307 is fixedly connected to the top of the guide rod 306, which enables the quick fixation of the limiting base 1, thereby effectively increasing the contact area between the bottom of the base 1 and the ground. The high friction of the rubber pad 305 ensures stable placement of the equipment, preventing external forces from causing the equipment to shift during use, and greatly improving the stability of the device during use. A rotating block 308 is fixedly connected to the top of the threaded rod 303. The design of the rotating block 308 facilitates the operation of the threaded rod 303 by the staff.

[0029] Working principle: Before using this double-sided grinding machine auxiliary feeding device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, the operator first moves the equipment near the double-sided grinder, so that one side of the support platform 211 is against the grinder. The operator then drives the servo motor 104 via the controller, which in turn drives the rotating roller 102. Through the interaction between the rotating roller 102 and the conveyor belt 103, the conveyor belt 103 transports the material. The conveyor belt 103 then transports the material to the top of the support platform 211, facilitating subsequent loading of material onto the support platform 211 by the operator. The controller drives the forward and reverse motor 210, which in turn drives the worm gear 205 to rotate. The rotation of the worm gear 205 drives the worm wheel 206, which in turn drives the rotating rod 204. The rotation of the rotating rod 204 drives the two sets of first bevel teeth 208, which in turn drives the second bevel teeth 209. The rotation of the second bevel teeth 209 then drives the screw 207. Due to the fit between the external screw 207 and the internal thread groove of the lifting rod 2071, thus… The rotation of screw 207 drives lifting rod 2071 to slide up and down inside sliding box 202. The movement of lifting rod 2071 drives longitudinal movement of housing 101, thereby enabling conveyor belt 103 to flexibly change the conveying direction according to the actual layout of double-sided grinding machine and material feeding requirements, accurately conveying materials to different positions around grinding machine, effectively coping with the complex and ever-changing space constraints of production site, realizing flexible loading or unloading of double-sided grinding machine, reducing the distance and difficulty of manual handling, and significantly reducing labor intensity. When the up and down movement of housing 101 drives support rod 213 to slide inside support tube 212, the operator can then thread the fixing knob 215 and fixing groove 214 together, thereby achieving the effect of quickly lifting and lowering housing 101 and supporting it, thus effectively reducing the phenomenon of housing 101 shifting and shaking due to external force collisions, improving the stability of equipment during use. Through the design of limit block 216, the rotation of rotating rod 204 can be made more stable. The operator can set a tensioning device inside housing 101 to improve the efficiency of conveyor belt 103.

[0030] By rotating the threaded rod 303 inside the fixed plate 302, the rotation of the threaded rod 303 causes the pressing plate 304 to move up and down against one side of the support plate 301. At this time, the movement of the pressing plate 304 causes the guide rod 306 to slide inside the fixed plate 302. At this time, the stop block 307 limits the guide rod 306. When the pressing plate 304 moves down, the rubber pad 305 presses against the ground, thereby achieving the effect of quickly fixing and limiting the base 1. This effectively increases the contact area between the bottom of the base 1 and the ground. Furthermore, the high friction of the rubber pad 305 ensures stable placement of the equipment, preventing the equipment from shifting due to external force collisions. This greatly improves the stability of the device during use. The design of the rotating block 308 facilitates the operation of the threaded rod 303 by the operator.
