Description

Technical Field

[0001] This utility model belongs to the field of production equipment and relates to the production of automobile engine brackets, specifically to a novel roller polishing equipment for automobile engine brackets. Background Technology

[0002] The engine mount is a critical component for securing the engine and bears its weight and dynamic forces during operation. However, manufactured steel, aluminum alloy, and cast iron mounts often have burrs and oxide layers on their surfaces. Therefore, surface treatment of the engine mount is necessary to improve its durability, stability, and optimize its performance.

[0003] When producing small engine mounts, tumble polishing is typically used. Tumble polishing equipment can polish multiple engine mounts simultaneously, improving production efficiency. However, current tumble polishing equipment involves filling a drum with abrasive material, placing the engine mount inside, and then rotating the drum to cause friction between the abrasive and the engine mount, removing burrs and oxide layers from its outer surface. After polishing, the engine mounts need to be removed from the drum. Currently, this is mostly done manually, which is time-consuming and labor-intensive, reducing production efficiency. Utility Model Content

[0004] This invention addresses the technical problem of manually removing engine mounts from the abrasive after polishing, which reduces production efficiency. It provides a novel roller polishing device for automotive engine mounts. By evenly arranging material boxes on the roller, the abrasive is collected in the boxes after polishing, allowing the engine mount to be screened out for easy removal. This improves production efficiency and facilitates sampling and inspection of the abrasive in the boxes, ensuring optimal polishing results.

[0005] The technical solution adopted by this utility model is as follows: a novel roller polishing device for automobile engine brackets is provided, including a roller and a roller drive structure, and a base plate. A back plate is fixedly installed on the base plate, and the roller is supported on the back plate by means of a bracket. Operating ports are evenly arranged circumferentially on the outer side wall of the roller. An open material box can be detachably installed on each operating port. The material box is connected to the roller. A screen and a gate are provided inside the material box. The screen is fixedly connected to the material box. The gate is close to the opening of the material box, and one end of the gate is sealed and extends out of the material box and slides into the material box. It is also fixedly connected to the material box by means of a locking component.

[0006] After adding abrasive and the engine mount to be polished into the drum, the drum is driven to rotate, causing the abrasive to come into frictional contact with the engine mount. This removes burrs and oxide layers from the outer surface of the engine mount. After the polishing process, the gate located in the material box at the bottom of the drum is first pulled outward, allowing the abrasive to flow into the material box. The screen inside the material box prevents the engine mount from entering the material box. Then, the gate is pushed back into the material box, and the position of the material box is changed to continue loading abrasive, thus separating the abrasive from the engine mount in the drum. After removing one of the material boxes from the drum, the engine mount can be easily removed. The material box contains abrasive, which can be sampled and inspected to determine the condition of the abrasive, allowing for timely replacement and ensuring the reliability of the engine mount polishing process.

[0007] To further optimize this technical solution, a fixing frame is provided on the periphery of the operation port, and the fixing frame is fixedly connected to the outer wall of the roller. The material box and the fixing frame can be detached and installed.

[0008] The fixed frame strengthens the operating port on the roller and provides an installation position for the material box, ensuring flexibility in use.

[0009] To further optimize this technical solution, the opening of the material box is provided with an outwardly protruding outer edge, which is sealed and abuts against the fixed frame and is fixedly connected to the fixed frame by means of a fixing component, and the locking component on the gate plate is locked and connected to the outer edge.

[0010] After the outward protruding edge of the material box abuts against the fixed frame, it ensures the sealing of the assembly between the material box and the roller, and the outer edge provides an anchor point for the installation of the material box and the locking and positioning of the gate, ensuring the reliability of use.

[0011] To further optimize this technical solution, the fastener includes a fixing bolt connected by a circumferential thread along the outer edge, and the fixing frame is provided with a screw hole that matches the fixing bolt.

[0012] The material box is fixed to the roller by means of the fixing bolts on the outer edge and the screw holes on the fixing frame. The fixing structure is simple, easy to disassemble and assemble, firm and reliable, and reduces operation and maintenance costs.

[0013] To further optimize this technical solution, the locking component includes a tightening bolt threaded onto the gate plate. The tightening bolt is located outside the material box and passes through the gate plate to abut against the outer edge of the material box.

[0014] The part of the gate plate that protrudes from the material box is connected to the tightening bolt. After the gate plate is pushed into the material box to close the space inside the material box, the tightening bolt is located at the outer edge of the material box. After the tightening bolt abuts against the outer edge, the gate plate is fixed on the material box. The structure is simple, easy to use and reliable.

[0015] To further optimize this technical solution, support shafts are coaxially fixedly installed at both ends of the roller, and the support shafts are rotatably installed with the bracket. Furthermore, the support shaft on one side of the roller is driven and installed with the drive structure.

[0016] The support shaft on the roller provides an installation position for the roller to be mounted on the bracket, and facilitates the drive structure to drive the roller to rotate through the support shaft.

[0017] To further optimize this technical solution, the drive structure includes a matching motor and a gearbox. The gearbox is fixedly installed with the back plate, and the output shaft of the gearbox is driven to be installed with the support shaft via a transmission assembly.

[0018] The gearbox can amplify the torque of the motor, ensuring smooth drive of the rollers, and has low operating and maintenance costs.

[0019] To further optimize this technical solution, the transmission component includes a matching transmission belt and pulleys, with the pulleys coaxially mounted with the output shaft and support shaft, respectively.

[0020] Belt drives have a simple structure, stable operation, and low maintenance costs.

[0021] To further optimize this technical solution, a handrail is fixedly installed at one end of the gate that extends out of the material box.

[0022] The handrail makes it easy to pull the gate, making it simple and flexible to use.

[0023] To further optimize this technical solution, mounting holes are evenly provided along the circumference of the base plate, and a counterweight can be detachably installed on the side of the base plate away from the back plate.

[0024] The mounting holes on the base plate facilitate fixing to the support surface using expansion bolts or anchor bolts, ensuring reliable use. Furthermore, by installing a counterweight on the side of the base plate away from the back plate, the center of gravity of the equipment is balanced, ensuring the stability of the equipment operation.

[0025] The beneficial effects of this utility model are as follows:

[0026] 1. By filling the drum with sand and placing the engine bracket inside, the drum is driven to rotate, causing the sand to come into contact with and rub against the engine bracket, thereby removing burrs and oxide layers from its surface, improving the smoothness of the engine bracket. The structure is simple, the use is stable and reliable, and the maintenance cost is low.

[0027] 2. After polishing the engine bracket, first pull the gate on the material box at the bottom of the roller outward to allow the sand in the roller to flow into the material box. The screen in the material box prevents the engine bracket from falling into the material box. Then push the gate back into the material box, change the position of the material box and continue loading sand to complete the sorting of sand and engine bracket. After removing one of the material boxes, take out the engine bracket. The operation is simple and improves production efficiency.

[0028] 3. The abrasive material in the material box is removed. By taking a sample of the abrasive material, its condition can be determined so that it can be replaced in a timely manner to ensure the polishing effect. After the new engine bracket is put into the drum, the material box is loaded onto the drum, and the gates on the material box are pulled out to refill the drum with abrasive material to continue the drum polishing of the engine bracket. It is flexible and convenient to use. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] Please see the appendix Figure 1 Appendix Figure 3A novel roller polishing device for automobile engine brackets includes a base plate 2, a back plate 3 fixedly installed on the base plate 2, a bracket 301 fixedly installed on the back plate 3, a roller 1 supported on the bracket 301, and support shafts 103 coaxially fixedly connected to both ends of the roller 1. The support shafts 103 are fixedly installed on the back plate 3 by means of the bracket 301, and bearings are coaxially fitted on the support shafts 103 to ensure the smooth rotation of the roller 1 within the bracket 301 and to improve the smoothness of the drive structure driving the roller 1. The bracket 301 includes a main support arm fixed on the back plate 3, the main support arm being rotatably installed with the support shafts 103, and a diagonal tie beam fixedly connected to the main support arm. The other end of the diagonal tie beam is fixedly installed to the back plate 3 to ensure the safety of supporting the roller 1.

[0038] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The drive structure for driving the rotation of the roller 1 includes a matching motor 5 and a gearbox 6. The gearbox 6 is fixedly mounted on the back plate 3. The output shaft of the gearbox 6 is driven to one of the support shafts 103 on the roller 1 via a transmission assembly. The transmission assembly can be a belt drive, including a matching transmission belt 7 and a pulley 8. The pulley 8 is coaxially mounted on the output shaft of the gearbox 6 and the support shaft 103 of the roller 1, respectively, thereby driving the roller 1 to rotate via the transmission belt 7. The structure is simple, stable in use, and low in operating cost.

[0039] Please see the appendix Figure 1 Appendix Figure 4 Appendix Figure 5 Operating openings 101 are evenly distributed around the outer side wall of the roller 1. Open material boxes 4 can be detachably installed on the operating openings 101. The material boxes 4 are connected to the roller 1 through the operating openings 101. The material boxes 4 can be fixed to the roller 1 by tightening bolts. The operation is simple, the fixation is firm and reliable, and it is easy to maintain. The opening of the material box 4 is provided with an outwardly protruding edge 403. The edge 403 provides an installation position for the fixing bolts 4031. A fixing frame 102 is fixedly installed on the roller 1. The fixing frame 102 is distributed around the operating openings 101 and is provided with screw holes 1021 to provide anchor points for the fixing bolts 4031. In this way, the material box 4 is tightened and fixed to the roller 1. The edge 403 of the material box 4 abuts against the fixing frame 102. A washer can be added to the fixing frame 102 to enhance the sealing between the material box 4 and the fixing frame 102.

[0040] Please see the appendix Figure 6The material box 4 is equipped with a screen 401 and a gate 402. The screen 401 is fixedly connected to the material box 4. The gate 402 is close to the opening of the material box 4, and one end of the gate 402 is sealed and protrudes from the material box 4 and slides into the material box 4. It is also fixedly connected to the material box 4 by means of a locking device. After the gate 402 is pushed into the material box 4, the gate 402 closes the material box 4, thereby blocking the communication between the material box 4 and the roller 1. After the gate 402 is pulled out from the material box 4, the material box 4 is connected to the roller 1. The end of the gate 402 that protrudes from the material box 4 is fixedly connected to a handle 4022. The handle 4022 facilitates the pulling of the gate 402 and makes it easier to use.

[0041] Please see the appendix Figure 1 When polishing the engine bracket 301, after removing one of the material boxes 4 from the roller 1, abrasive is first added to the roller 1. When adding abrasive for the first time, the gate plate 402 closes the material box 4 to prevent abrasive from flowing into the material box 4. Then, the engine bracket 301 is placed into the roller 1. Before starting the drive structure to drive the roller 1 to rotate, the gate plate 402 is fixed to the material box 4 by a locking member. The locking member can be a top bolt 4021, which is threaded onto the gate plate 402 and located outside the material box 4. It passes through the gate plate 402 and abuts against the outer edge 403 of the material box 4, thereby fixing the gate plate 402 to the roller 1. During the rotation of the roller 1, the abrasive rubs against the engine bracket 301, thereby removing burrs and oxide layers from the engine bracket 301 and improving the smoothness of the engine bracket 301.

[0042] Please see the appendix Figure 2 After polishing the engine bracket 301, firstly, release the locking state of the gate 402 located on the bottom material box 4 of the roller 1, and pull it outward through the handle 4022, so that the sand in the roller 1 enters the material box 4. The screen 401 fixedly installed in the material box 4 blocks the sand and the engine bracket 301, preventing the engine bracket 301 from entering the material box 4. Then, the gate 402 re-closes the material box 4, and the position of the material box 4 is changed, so that all the sand in the roller 1 is recovered by the material box 4. Then, by removing one of the material boxes 4, it is convenient to take out the engine bracket 301, reduce manual sorting, improve production efficiency, and sample the sand in the removed material box 4 to determine the state of the sand, so as to replace the sand in time and ensure the reliability of polishing.

[0043] Please see the appendix Figure 2 Appendix Figure 5When the gate 402 is pulled out, since the roller 1 is supported on the back plate 3, and the gate 402 located at the bottom of the roller 1 is usually pulled out, the pulling out of the gate 402 is not interfered with. The base plate 2 supporting the roller 1 has mounting holes 201 evenly opened along the circumference, which can be directly fixed to the support surface by expansion bolts or anchor bolts to ensure the reliability of use. Alternatively, a counterweight 202 can be installed on the side away from the back plate 3 to balance the force on the base plate 2 and ensure the reliability of use.

[0044] The working principle of this novel roller polishing equipment for automotive engine mounts is as follows: First, one of the material boxes 4 on the roller 1 is removed. Then, abrasive is added to the roller 1, and the engine mount 301 to be polished is placed inside. The previously removed material box 4 is then reinstalled on the roller 1, and the roller 1 is driven to rotate via a drive structure. Before rotation, the gate plate 402 is re-inserted into the material box 4 and locked by the tightening bolt 4021. After the roller 1 begins to rotate, the abrasive inside contacts and rubs against the engine mount 301, thus polishing the engine mount 301. The abrasive reduces the impact caused by the mutual contact of the engine mounts 301, ensuring polishing reliability. After polishing, the gate plate 402 on the material box 4 at the bottom of the roller 1 is pulled outwards to allow the abrasive inside the roller 1 to flow into the material box 4. The screen 401 in the material box 4 prevents the engine mount 301 from falling into the material box 4. Then, the gate plate 402 is pushed back into the material box 4, the position of the material box 4 is changed, and the gate plate 402 is pulled out again to load abrasive. After loading the abrasive material from roller 1 into the material box 4, the abrasive material and engine bracket 301 are sorted. After removing one of the material boxes 4, the engine bracket 301 is taken out. The operation is simple and improves production efficiency. Furthermore, the abrasive material in the unloaded material box 4 can be sampled to determine its condition, so that the abrasive material can be replaced in a timely manner to ensure the polishing effect.
