Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a rotary arm polishing machine. Background Technology

[0002] A polishing machine is a type of grinding equipment primarily used for polishing components. Currently, there are two types of hanging polishing machines on the market. The first type uses a detachable central shaft to load the polishing fixture. Before polishing, an external carrier (forklift or overhead crane) is used to remove the polishing fixture from the abrasive bin. The components on the fixture are then manually replaced. The fixture is then placed back into the abrasive bin using the carrier, the cover is closed, and the fixture rotates within the abrasive to begin polishing. Using an external carrier to lift the polishing fixture not only increases the cost of the equipment but also increases the risk of accidents during lifting, reduces work efficiency, and increases production costs.

[0003] The second type uses a fixed central shaft that carries an abrasive bin and multiple polishing fixtures that rotate relative to the central shaft. The plant abrasive is placed in the abrasive bin, the central shaft rotates together with the abrasive bin, and the polishing fixtures rotate relative to each other to perform polishing operations. For example, Chinese patent CN216633929U discloses a horizontal grinding and polishing machine, including a barrel; a grinding rotation mechanism including a frame on which a first main shaft and a second main shaft are rotatably arranged coaxially at intervals. A first shaft is rotatably mounted on the first main shaft, parallel to but not aligned with the first main shaft. A second shaft is rotatably mounted on the second main shaft, parallel to but not aligned with the second main shaft. A first connector for connecting one end of the grinding frame is provided on the first shaft, and a second connector for connecting the other end of the grinding frame is provided on the second shaft. A rotation drive source assembly is capable of drivingly connecting to the first main shaft and / or the second main shaft, and also capable of drivingly connecting to the first shaft and / or the second shaft, so that the grinding frame between the first and second connectors rotates within the barrel and synchronously revolves around the first main shaft, thereby improving grinding quality. Because a single power source simultaneously drives the rotation of the first and second main shafts, and to facilitate workpiece placement, the grinding frame can rotate within the barrel, thus affecting the rotation speed of the grinding frame within the barrel and extending the polishing time. Reduced light slickness efficiency Utility Model Content

[0004] To solve the above problems, this utility model provides a swing arm type screed machine that does not require external carriers to disassemble the suspension shaft.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rotary arm polishing machine includes a base and a hollow abrasive chamber fixedly installed on the base. The abrasive chamber has a machine box on both sides; a swing arm is rotatably arranged between the two machine boxes; a suspension shaft for suspending workpieces is provided at the end of the swing arm; the top of the abrasive chamber has an opening; the rotation of the swing arm drives the suspension shaft to be taken out or put in from the opening at the top of the abrasive chamber.

[0006] As a preferred embodiment of this utility model, the chassis is provided with a power component for driving the swing arm to rotate, and the swing arm is provided with a mounting chamber; the mounting chamber is provided with a drive component for driving the suspension shaft to rotate.

[0007] As a preferred embodiment of this utility model, the swing arm includes a connecting shaft rotatably mounted between two housings, and two connecting arms with identical structures are fixedly mounted on the outer surface of the connecting shaft, with one end of the connecting arm fixedly mounted on the connecting shaft; a suspension shaft is connected to the other end of the connecting arm.

[0008] In a preferred embodiment of this invention, the power component includes a connecting disc fixedly mounted at the end of a connecting shaft, a power shaft integrally formed on the connecting disc, a worm gear reducer fixedly mounted on the power shaft, and the input end of the worm gear reducer fixedly connected to a servo motor; both the servo motor and the worm gear reducer are fixed inside the housing.

[0009] As a preferred embodiment of the present invention, the mounting chamber includes a mounting hole that penetrates the connecting shaft, the connecting arm has a connecting chamber, and the side wall of the connecting shaft has a connecting port that penetrates the mounting hole.

[0010] In a preferred embodiment of this invention, the driving component includes a drive shaft rotatably mounted in a mounting hole, two drive sprockets fixedly mounted on the drive shaft, and the drive sprockets located at the center of the connection port; a driven shaft rotatably mounted on the end of the connecting arm away from the connecting shaft, and the suspension shaft connected to the driven shaft; a driven sprocket fixedly mounted on the driven shaft; the driven sprocket located within the connecting cavity; a transition seat provided within the connecting cavity, a transition shaft fixedly mounted on the transition seat, and an auxiliary sprocket rotatably mounted on the transition shaft; and a chain sleeved between the driven sprocket, the auxiliary sprocket, and the drive sprocket.

[0011] As a preferred embodiment of this invention, one end of the drive shaft extends to the outside of the connecting shaft and is located inside the housing; a pulley is fixedly installed at the end of the drive shaft, the pulley is located inside the housing, a drive motor is fixedly installed inside the housing, and the output end of the drive motor is connected to the pulley for transmission.

[0012] As a preferred embodiment of this utility model, the two sides of the connecting arm are provided with elongated holes for through-connection of the connecting chamber, and the top surface of the connecting arm is provided with a fixing hole for through-connection of the connecting chamber; fasteners are threadedly connected to the transition seat through the elongated holes and the fixing holes respectively.

[0013] As a preferred embodiment of this utility model, a connector is fixedly installed on the driven shaft, and a semi-circular supporting half shaft is integrally formed at the end of the connector.

[0014] As a preferred embodiment of this invention, the side of the abrasive chamber is provided with a notch; when the suspension shaft is located inside the abrasive chamber, the connecting arm on the swing arm is engaged in the notch.

[0015] The beneficial effects of this utility model are as follows: 1. By rotating the swing arm clockwise, the suspension shaft is driven from the outside of the abrasive chamber through the opening at the top of the abrasive chamber and into the abrasive chamber. Conversely, the swing arm removes the suspension shaft from the opening at the top of the abrasive chamber, placing the suspension shaft outside the abrasive chamber for easy workpiece replacement. This eliminates the hassle of disassembling the suspension shaft using an external carrier, thereby eliminating safety hazards and facilitating production operations.

[0016] 2. The swing arm is driven to rotate at low speed by a power component, while the suspension shaft is driven to rotate at high speed by a drive component. Separate power sources are used to drive the rotation of the swing arm and suspension shaft respectively. This ensures operator safety through the low-speed rotation of the swing arm, while the high-speed rotation of the suspension shaft improves production efficiency. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-6 As shown, the rotary arm polishing machine of this utility model includes a base 01 and a hollow abrasive chamber 02 fixedly mounted on the base 01. A housing 03 is provided on both sides of the abrasive chamber 02. A swing arm 04 is rotatably mounted between the two housings 03. A suspension shaft 05 for suspending workpieces is provided at the end of the swing arm 04. The top of the abrasive chamber 02 is open. By rotating the swing arm 04 clockwise, the suspension shaft 05 passes through the top of the abrasive chamber 02 from the outside and enters the abrasive chamber 02. Conversely, the swing arm 04 removes the suspension shaft 05 from the opening at the top of the abrasive chamber 02, placing the suspension shaft 05 outside the abrasive chamber 02. This eliminates the hassle and safety hazards of disassembling the suspension shaft 05 using an external carrier and facilitates production operations.

[0026] One of the housings 03 houses a power unit for driving the rotation of the swing arm 04, which in turn contains a mounting chamber. The mounting chamber contains a drive unit for driving the rotation of the suspension shaft 05. Since the swing arm 04 requires low-speed rotation, while the suspension shaft 05 requires high-speed rotation to achieve the polishing effect, separate power sources are used to drive the rotation of the swing arm 04 and the suspension shaft 05 respectively. The low-speed rotation of the swing arm 04 is primarily for operator safety, while the high-speed rotation of the suspension shaft 05 is for improving production efficiency.

[0027] The swing arm 04 includes a connecting shaft 06 rotatably mounted between two housings 03 via bearings. Two identical connecting arms 07 are fixedly mounted on the outer surface of the connecting shaft 06, each adjacent to a housing 03. One end of each connecting arm 07 is fixed to the connecting shaft 06 with fasteners. A suspension shaft 05 connects to the other end of each connecting arm 07. The connecting arm 07 has an arc-shaped profile. This arc-shaped design allows the swing arm 04 to move the suspension shaft 05 closer to the bottom of the abrasive chamber 02 after it enters the chamber. This ensures full contact between the workpiece on the suspension shaft 05 and the abrasive material in the chamber 02, improving production efficiency.

[0028] Please see Figure 2 As shown, a connecting disc is fixedly mounted on one end of the connecting shaft 06 using fasteners. A power shaft 08 is integrally formed on the connecting disc, and a worm gear reducer 09 is fixedly mounted on the power shaft 08. The input end of the worm gear reducer 09 is fixedly connected to the servo motor 10. Both the servo motor 10 and the worm gear reducer 09 are fixed inside the housing 03. It should be noted that the worm gear reducer 09 is a purchased standard part. Utilizing the high torque and low speed output characteristics of the worm gear reducer 09, the swing arm 04 operates at a low speed during rotation, thereby improving the safety of the equipment during operation. The servo motor 10 drives the rotation of the connecting shaft 06, which in turn drives the connecting arm 07 and the suspension shaft 05 to rotate.

[0029] The connecting shaft 06 has a through mounting hole 11, the connecting arm 07 has a connecting chamber 12, and the side wall of the connecting shaft 06 has a connecting port 13 that passes through the mounting hole 11.

[0030] Please see Figure 2-4As shown, a drive shaft 14 is rotatably mounted in the mounting hole 11 via a bearing. One end of the drive shaft 14 extends to the outside of the connecting shaft 06 and is located inside the housing 03. A pulley 15 is fixedly mounted on the end of the drive shaft 14. The pulley 15 is located inside the housing 03, and a drive motor 16 is fixedly mounted inside the housing 03. The output end of the drive motor 16 is connected to the pulley 15 via a V-belt drive. The rotation of the motor drives the drive shaft 14 to rotate within the connecting shaft 06. Two drive sprockets 22 are fixedly mounted on the drive shaft 14, and the drive sprockets 22 are located at the center of the connecting port 13. A driven shaft 17 is rotatably mounted on the end of the connecting arm 07 away from the connecting shaft 06 via a bearing. One end of the driven shaft 17 extends to the outside of the connecting arm 07 and connects to the suspension shaft 05. A driven sprocket 18 is fixedly mounted on the driven shaft 17. The driven sprocket 18 is located inside the connecting chamber 12. A transition seat 19 is provided inside the connecting chamber 12, and the transition seat 19 is located at the center of the connecting arm 07. A transition shaft 20 is fixedly mounted on the transition seat 19, and an auxiliary sprocket 21 is rotatably mounted on the transition shaft 20 via bearings. Since the connecting arm 07 is arc-shaped, the auxiliary sprocket 21 is positioned at the center of the connecting arm 07, making the chain fitted onto the driven sprocket 18, the auxiliary sprocket 21, and the drive sprocket 22 more closely resemble the shape of the connecting arm 07. The servo motor 10 drives the drive shaft 14 to rotate, which in turn drives the driven shaft 17 to rotate via the chain. The rotation of the driven shaft 17, in turn, drives the rotation of the suspension frame.

[0031] Please see Figure 5 As shown, the two sides of the connecting arm 07 are provided with elongated holes 23 that are connected to the connecting chamber 12. Fasteners are threadedly connected to the transition seat 19 through the elongated holes 23. The design of the elongated holes 23 ensures that when the transition seat 19 is adjusted up and down within the connecting chamber 12, the fasteners used to fix the transition seat 19 can move within the elongated holes 23. It should be noted that the fasteners described in this application are one of bolts, screws, and screws, preferably bolts.

[0032] To prevent the transition seat 19 from remaining unchanged after adjustment, a fixing hole 24 for through connection to the connecting chamber 12 is provided on the top surface of the connecting arm 07. A nut is fixedly connected to the transition seat 19 by welding. A fastener passes through the fixing hole 24 and is connected to the nut, with a nut threaded onto the fastener. The nut is positioned on the outside of the connecting arm 07 and abuts against the outside of the connecting arm 07. When the nut abuts against the outside of the connecting arm 07, it restricts the vertical movement of the transition seat 19.

[0033] Please see Figure 6As shown, a connector 25 is fixedly mounted on the driven shaft 17. A semi-circular supporting half-shaft 26 is integrally formed at the end of the connector 25. A semi-circular fixed half-shaft 27 is detachably connected to the supporting half-shaft 26 via fasteners. Both the supporting half-shaft 26 and the fixed half-shaft 27 are provided with fixing grooves 28, which combine to form a complete connecting hole with a polygonal cross-section. Both ends of the suspension shaft 05 are positioned within the connecting hole. During assembly, the fixed half-shaft 27 is removed from the supporting half-shaft 26, and both ends of the suspension shaft 05 are placed into the fixing grooves 28 of the supporting half-shaft 26. Then, the fixing grooves 28 on the fixed half-shaft 27 are fitted onto the ends of the suspension shaft 05, and the fixed half-shaft 27 and the supporting half-shaft 26 are fixed with fasteners. The two ends of the suspension shaft 05 are then fixed within the connecting hole. Because the cross-section of the connecting hole is polygonal, the ends of the rotating shaft are also polygonal. This polygonal design ensures that the suspension shaft 05 rotates synchronously when the driven shaft 17 drives the connector 25 to rotate. When it is necessary to remove the suspension shaft 05 from the connector 25, the fixed half-shaft 27 is removed from the supporting half-shaft 26, and then the suspension shaft 05 can be removed from the connector 25. Through this detachable connection, after the polished workpiece is removed from the abrasive chamber 02, the operator can replace the suspension shaft 05 to polish the next batch of workpieces. There is no need to wait for the operator to remove the workpiece from the suspension shaft 05 and reattach a new workpiece, thus improving production efficiency.

[0034] Please see Figure 1 The abrasive chamber 02 shown has a notch 29 on its side. When the power unit drives the swing arm 04 to rotate and moves the suspension shaft 05 into the abrasive chamber 02, the connecting arm 07 on the swing arm 04 is located within the notch 29. This prevents the top of the connecting arm 07 from being higher than the opening at the top of the abrasive chamber 02, thus preventing the cover plate at the top of the abrasive chamber 02 from getting dry with the connecting arm 07.
