Description

Technical Field

[0001] The invention relates to the technical field of polishing and grinding, and in particular to a plate polishing device. Background Art

[0002] In the processing of nickel alloy plates, polishing is a key process, which is extremely important for improving the surface quality of the plates, improving the appearance of the plates and meeting the requirements of subsequent processes. The traditional nickel alloy plate polishing process usually uses two steps, rough polishing and fine polishing, to achieve gradual refinement of the plate surface.

[0003] In the prior art, the rough polishing and fine polishing processes often rely on two independent devices to complete them separately. Although this method can meet the requirements for the polishing quality of nickel alloy plates to a certain extent, it has many disadvantages. First of all, the setting of the two devices will inevitably occupy a large site space, which will undoubtedly increase the site rental cost and space planning difficulty for enterprises with limited site resources. For example, in some small processing plants or workshops, after the limited site area is largely occupied by two polishing equipment, the space left for other production links or material storage will become very cramped, which seriously restricts the rationality and efficiency of the overall production layout.

[0004] Secondly, when using two devices for rough polishing and fine polishing, the sheet metal parts need to be transferred between the two devices. During the transfer process, due to the complexity of the operation and possible improper manual handling, it is very easy to cause scratches, bumps and other damages to the surface of the sheet metal parts, resulting in reduced product quality and increased scrap rate. Moreover, this transfer operation will also consume a lot of time and labor costs, reduce production efficiency, and extend the production cycle, which is not conducive to the company's rapid response to order needs and efficient production in the fierce market competition.

DETAILED DESCRIPTION

[0058] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0060] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0062] Reference Figure 1 to Figure 11, which is the first embodiment of the present invention, proposes a plate polishing equipment for polishing a sheet metal part 1, including a frame 2; a workbench 3 is arranged to slide horizontally relative to the frame 2, and the workbench 3 is used to hold the sheet metal part 1; a rotating frame 4 is rotatably arranged relative to the frame 2; a rough polishing wheel 5 is rotatably arranged on one side of the rotating frame 4; a fine polishing wheel 6 is rotatably arranged on the other side of the rotating frame 4, and after the rotating frame 4 rotates, the fine polishing wheel 6 or the rough polishing wheel 5 abuts against the surface of the sheet metal part 1.

[0063] In this embodiment, in order to solve the problem that two devices are required for rough polishing and fine polishing of nickel alloy plates in the related art, and the two devices occupy a large area, a plate polishing device is designed. The frame 2 is the supporting structure of the entire device. A workbench 3 is set on the frame 2, and the workbench 3 slides horizontally relative to the frame 2, and the sheet metal part 1 is placed on the workbench 3 and its position is ensured to be fixed. Then the rotating frame 4 is installed so that it can rotate flexibly relative to the frame 2. A rough polishing wheel 5 is installed on one side of the rotating frame 4, and a fine polishing wheel 6 is installed on the other side of the rotating frame 4. When the sheet metal part 1 is placed on the workbench 3, the rough polishing wheel 5 is close to the workbench 3 due to the initial setting. At this time, the workbench 3 is driven to slide horizontally by an external driving device, so that the rough polishing wheel 5 contacts the surface of the sheet metal part 1, and then the rough polishing wheel 5 is started to drive the motor to start the rough polishing process. After the rough polishing is completed, the rotating frame 4 is rotated to allow the fine polishing wheel 6 to approach the workbench 3. The workbench 3 is driven to slide in the opposite direction again, so that the fine polishing wheel 6 contacts the sheet metal part 1, and the fine polishing wheel 6 is started to drive the motor to perform the fine polishing operation.

[0064] The advantage is that the rough polishing wheel 5 and the fine polishing wheel 6 are integrated into the same device, and the switching contact with the sheet metal part 1 is achieved by the rotating frame 4, which reduces the equipment footprint and improves the space utilization rate of the site. It avoids the transfer of the sheet metal part 1 between different devices, reduces the risk of surface damage, and improves product quality. The equipment purchase, installation and maintenance costs are reduced, the operation is more convenient and efficient, and the polishing process can be completed by simply switching on the same device, which improves production efficiency and is suitable for a variety of production environments.

[0065] Furthermore, it also includes a mounting arm 7, which is rotatably set on the frame 2, and one end of the mounting arm 7 has a first mounting portion 701, and the rotating frame 4 is rotatably set on the first mounting portion 701; the telescopic member 8 is hinged relative to the frame 2, and the extended end of the telescopic member 8 is hinged relative to the other end of the mounting arm 7. After the telescopic member 8 is extended, it drives the rotating frame 4 to approach the sheet metal part 1.

[0066] In this embodiment, a first mounting portion 701 is provided at one end of the mounting arm 7, and the rotating frame 4 is rotatably mounted on the first mounting portion 701. A telescopic member 8 is mounted on the frame 2, and the extended end of the telescopic member 8 is connected to the other end of the mounting arm 7 by a suitable hinge structure. When it is necessary to bring the rotating frame 4 close to the sheet metal part 1, the telescopic member 8, such as a hydraulic pump or a motor-driven screw mechanism, is started to push the extended end of the telescopic member 8 out. Due to the hinged relationship, the mounting arm 7 will rotate around the rotation axis between it and the frame 2, thereby driving the rotating frame 4 to approach the sheet metal part 1 placed on the workbench 3. By controlling the extended length of the telescopic member 8, the distance between the rotating frame 4 and the sheet metal part 1 can be accurately adjusted.

[0067] The advantage is that, with the synergistic effect of the mounting arm 7 and the telescopic member 8, the distance between the rotating frame 4 and the polishing wheel and the sheet metal part 1 can be conveniently and accurately adjusted. This design enables the equipment to flexibly adjust the polishing wheel position according to the polishing requirements of different sheet metal parts 1, such as different thickness, material and surface roughness requirements, thereby significantly improving the accuracy and quality of polishing.

[0068] Furthermore, the rotating frame 4 has a second mounting portion 401, and also includes a limiting plug plate 9, which is arranged on the first mounting portion 701, and the limiting plug plate 9 has a first limiting hole 901 and a second limiting hole 902; the first limiting rod 10 is slidably arranged on one side of the second mounting portion 401, and after the rotating frame 4 rotates to make the rough polishing wheel 5 close to the workbench 3, one end of the first limiting rod 10 is aligned with the first limiting hole 901, and after the first limiting rod 10 slides, one end enters the first limiting hole 901, which is used to limit the relative position of the rough polishing wheel 5 and the mounting arm 7; the second limiting rod 11 is slidably arranged on the first On one side of the second mounting portion 401, after the rotating frame 4 rotates to make the fine polishing wheel 6 approach the workbench 3, one end of the second limit rod 11 is aligned with the second limit hole 902, and after the second limit rod 11 slides, one end enters the second limit hole 902, which is used to limit the relative position of the fine polishing wheel 6 and the mounting arm 7; there are a plurality of first elastic members 12, and one end of the plurality of first elastic members 12 acts on the first limit rod 10 and the second limit rod 11 respectively, and the other ends of the plurality of first elastic members 12 all act on the second mounting portion 401, which is used to provide a force for the first limit rod 10 and the second limit rod 11 to slide toward the limit plug plate 9.

[0069] In this embodiment, on one side of the second mounting portion 401 of the rotating frame 4, guide grooves for the first limiting rod 10 and the second limiting rod 11 to slide are respectively provided, and the first limiting rod 10 and the second limiting rod 11 are placed therein to ensure that they can slide smoothly in the grooves. On the first mounting portion 701 of the mounting arm 7, a limiting plug plate 9 is firmly installed, and the first limiting hole 901 and the second limiting hole 902 are precisely processed on the limiting plug plate 9. When the rotating frame 4 rotates to the point where the rough polishing wheel 5 is close to the workbench 3, under the elastic force of the first elastic member 12 such as a spring on the second mounting portion 401, the first limiting rod 10 slides smoothly along the guide groove toward the direction close to the limiting plug plate 9 until one end thereof is accurately inserted into the first limiting hole 901, thereby successfully limiting the relative position of the rough polishing wheel 5 and the mounting arm 7, and preventing the rough polishing wheel 5 from unnecessary displacement during operation. Similarly, when the rotating frame 4 rotates to make the fine polishing wheel 6 approach the workbench 3, the second limit rod 11, under the push of the elastic force of the first elastic member 12, slides toward the limit plug plate 9 and makes one end accurately enter the second limit hole 902, thereby limiting the relative position of the fine polishing wheel 6 and the mounting arm 7, and ensuring the stability of the fine polishing process.

[0070] The advantage is that, through the clever combination of the carefully designed limit plug plate 9, the limit rod and the elastic member, after the rough polishing wheel 5 or the fine polishing wheel 6 reaches the predetermined working position, it can be quickly and reliably limited.

[0071] Furthermore, the first limiting rod 10 has a first abutting portion 1001 at one end away from the limiting plug plate 9, and the second limiting rod 11 has a second abutting portion 1101 at one end away from the limiting plug plate 9. It also includes a first abutting rod 13, one end of which is arranged at one end of the workbench 3, and the first abutting rod 13 has a first abutting surface 1301. After the workbench 3 slides, the first abutting surface 1301 abuts against the first abutting portion 1001, driving one end of the first limiting rod 10 to disengage from the first limiting hole 901; one end of the second abutting rod 14 is arranged at the other end of the workbench 3, and the second abutting rod 14 has a second abutting surface 1401. After the workbench 3 slides, the second abutting surface 1401 abuts against the second abutting portion 1101, driving the second limiting rod 11 to disengage from the second limiting hole 902.

[0072] In this embodiment, when the rough polishing process begins, the first limit rod 10 is plugged into the first limit hole 901 under the action of the first elastic member 12 to fix the position of the rough polishing wheel 5. As the rough polishing process proceeds, the workbench 3 continues to slide under the drive mechanism. After the rough polishing work is completed, when it reaches the limit position, the first abutting surface 1301 is tightly abutted with the first abutting portion 1001. Due to the continuous movement of the workbench 3, a stable thrust is given to the first abutting portion 1001, overcoming the resistance of the first elastic member 12, and prompting the first limit rod 10 to smoothly disengage from the first limit hole 901 along the predetermined sliding path. At this time, the rotating frame 4 can be rotated to allow the fine polishing wheel 6 to smoothly approach the workbench 3. Subsequently, the workbench 3 slides in the opposite direction to carry out the fine polishing process. After the fine polishing is completed, the workbench 3 continues to slide again until the second abutment surface 1401 contacts the second abutment portion 1101, and relies on the sliding force of the workbench 3 to push the second limit rod 11 to slide, thereby releasing the position restriction of the fine polishing wheel 6, preparing for the next round of operation or equipment adjustment.

[0073] The advantage is that, by utilizing the ingenious abutment design between the workbench 3 and the limit rod, the automatic operation of releasing the limit of the rough polishing wheel 5 and the fine polishing wheel 6 is realized.

[0074] Furthermore, the second abutment rod 14 has an abutment slope 1402. After the workbench 3 slides, the abutment slope 1402 abuts against the fine polishing wheel 6, pushing the rotating frame 4 to rotate, so that the rough polishing wheel 5 is close to the workbench 3. It also includes a torsion spring, which is arranged on the first mounting part 701. The two ends of the torsion spring act on the first mounting part 701 and the rotating frame 4 respectively, so as to provide a force to move the rough polishing wheel 5 away from the workbench 3.

[0075] In this embodiment, an abutment slope 1402 is machined on the second abutment rod 14 to ensure that it can effectively transmit the force when it contacts the fine polishing wheel 6. A torsion spring is accurately installed at the connection joint between the first mounting portion 701 and the rotating frame 4, so that its two ends can act on the first mounting portion 701 and the rotating frame 4 respectively, providing a stable and appropriate torque for the rotation of the rotating frame 4.

[0076] When the rough polishing operation is completed, the workbench 3 slides in a predetermined direction driven by the power source, and the first abutting surface 1301 and the first abutting portion 1001 are precisely docked and generate an interaction force. As the workbench 3 continues to slide, the force overcomes the elastic force of the first elastic member 12, driving the first limit rod 10 to smoothly slide out of the first limit hole 901 along the designed track, and the position limit of the rough polishing wheel 5 is released. Due to the initial torque of the torsion spring, the rotating frame 4 immediately starts to rotate, and the rotation process is smooth and the direction is accurate, until the second limit rod 11 smoothly enters the second limit hole 902 under the elastic force and structural guidance of its own first elastic member 12, and the fine polishing wheel 6 then approaches the workbench 3 and stabilizes at the initial position required for the fine polishing process, ready for fine polishing.

[0077] As the workbench 3 slides in the opposite direction, after the fine polishing process is completed, the workbench 3 is driven by power again to continue to slide in the corresponding direction, and the second abutting surface 1401 and the second abutting portion 1101 gradually approach and finally abut, and the interaction force between the two causes the second limit rod 11 to overcome the elastic force of the first elastic member 12 and disengage from the second limit hole 902, and the position restriction of the fine polishing wheel 6 is released. At the same time, the abutting inclined surface 1402 is in close contact with the fine polishing wheel 6. As the workbench 3 continues to slide, the abutting inclined surface 1402 gives the fine polishing wheel 6 a lateral thrust, which causes the rotating frame 4 to overcome the torque of the torsion spring and rotate in the opposite direction, so that the rough polishing wheel 5 gradually approaches the workbench 3. When the workbench 3 slides to the specified position, the first limit rod 10 enters the first limit hole 901 again accurately under the action of the first elastic member 12, and the position of the rough polishing wheel 5 is re-controlled, and the equipment returns to the initial rough polishing wheel 5 preparation state or can perform a new round of polishing cycle according to subsequent instructions.

[0078] Furthermore, the rotating frame 4 has a slide groove 402 and also includes a dust suction roller 16, one end of the dust suction roller 16 rotates and is slidably set in the slide groove 402. After the rotating frame 4 rotates, the dust suction roller 16 abuts against the sheet metal part 1 before the rough polishing wheel 5 or the fine polishing wheel 6. After the dust suction roller 16 slides in the slide groove 402, the rough polishing wheel 5 or the fine polishing wheel 6 abuts against the sheet metal part 1; there are a plurality of second elastic members 17, one end of several second elastic members 17 is respectively connected to the two sides of one end of the dust suction roller 16, and the other ends of several second elastic members 17 are connected to the inner wall of the slide groove 402, and several second elastic members 17 are used to provide force for the dust suction roller 16 to move to the middle of the slide groove 402.

[0079] In this embodiment, a slide groove 402 is machined on the rotating frame 4, a sliding block capable of reciprocating sliding is arranged in the slide groove 402, one end of the dust collecting roller 16 is mounted on the sliding block through a bearing, and the sliding block slides in the slide groove 402, so that the dust collecting roller 16 can not only flexibly rotate around its own axis, but also perform smooth linear sliding along the slide groove 402. A plurality of second elastic members 17 are symmetrically connected between the two sides of one end of the dust collecting roller 16 and the inner wall of the slide groove 402 to provide a suitable elastic force for the dust collecting roller 16 to move to the middle of the slide groove 402.

[0080] When the rotating frame 4 rotates to the right position, the dust suction roller 16, driven by the rotating action of the rotating frame 4, contacts the sheet metal part 1 before the rough polishing wheel 5 or the fine polishing wheel 6. At the moment of contact, due to the unevenness of the surface of the sheet metal part 1 and the contact force, the dust suction roller 16 will slide in the slide groove 402. At this time, the second elastic member 17 will produce corresponding elastic deformation according to the sliding displacement of the dust suction roller 16 and provide restoring force, so that the dust suction roller 16 always tends to move to the middle position of the slide groove 402 during the sliding process, thereby ensuring that the contact pressure between the dust suction roller 16 and the sheet metal part 1 is uniform and stable.

[0081] The advantage is that the setting of the dust roller 16 and its unique elastic mounting structure play a positive role in many aspects. After the polishing process, the surface of the sheet metal part 1 can be effectively cleaned and dusted to remove various impurities such as dust and debris, greatly reducing the risk of scratches, wear and other damages caused by these impurities to the polishing wheel and the surface of the sheet metal part 1 during the polishing process. At the same time, the elastic mounting design of the dust roller 16 enables it to adapt to the microscopic undulations and unevenness of the surface of the sheet metal part 1, ensuring that the contact state between the dust roller 16 and the sheet metal part 1 is always in the best state during the entire cleaning process.

[0082] Furthermore, it also includes an adjusting device, through which the extended end of the telescopic member 8 is hinged to the other end of the mounting arm 7, and the adjusting device includes a connecting rod 18, which is threadedly connected to the extended end of the telescopic member 8; a connecting block 19 is hinged to the mounting arm 7, and the connecting rod 18 is rotatably set on the connecting block 19.

[0083] In this embodiment, a mounting block is fixedly installed at the extended end of the telescopic member 8, and the mounting block is processed with an internal thread. One end of the connecting rod 18 is processed with an external thread that matches it, and the end of the connecting rod 18 with the external thread is screwed into the internal thread of the mounting block, and its relative position in the mounting block is adjusted by rotating the connecting rod 18. A hinge seat is set at the other end of the mounting arm 7, and one end of the connecting block 19 is connected to the hinge seat through a hinge, so that the connecting block 19 can rotate around the hinge point. The other end of the connecting rod 18 is connected to the other end of the connecting block 19, which not only ensures that the connecting rod 18 and the connecting block 19 can rotate smoothly relative to each other, but also maintains the stability and reliability of the overall structure. Since the extended length of the telescopic member 8 is fixed, when it is necessary to adjust the posture of the mounting arm 7 to change the distance between the throwing wheel and the sheet metal part 1, the operator uses a tool such as a wrench to rotate the connecting rod 18. Due to the transmission action of the thread, the connecting rod 18 will move along its axial direction in the mounting block. This movement process will drive the connecting block 19 to produce a displacement change relative to the connecting rod 18, thereby causing the mounting arm 7 to rotate around the connection point between it and the frame 2, and finally achieving precise adjustment of the mounting arm 7 and the polishing wheel position installed on the rotating frame 4 to meet different polishing process requirements.

[0084] Furthermore, the connecting block 19 is slidably set on the connecting rod 18, and the adjusting device also includes a third elastic member 20, and the two ends of the third elastic member 20 act on the connecting rod 18 and one side of the connecting block 19 respectively, for providing a force to move the connecting block 19 away from the telescopic member 8; the fastener 21 is threadedly connected and set at one end of the connecting rod 18 away from the telescopic member 8, and abuts against the other side of the connecting block 19, for limiting the relative position of the connecting block 19 on the connecting rod 18.

[0085] In this embodiment, the connecting block 19 is sleeved on the connecting rod 18 so that the connecting block 19 can smoothly slide axially along the connecting rod 18. One end of the third elastic member 20 is fixed at a preset position of the connecting rod 18, and the other end is tightly connected to one side of the connecting block 19, continuously providing a thrust for the connecting block 19 away from the telescopic member 8. A fastener 21 is installed at the end of the connecting rod 18 away from the telescopic member 8 by threaded connection.

[0086] When it is necessary to polish a sheet metal part 1 with a significant protrusion, if the rough polishing wheel 5 or the fine polishing wheel 6 contacts the protrusion, since the connecting block 19 can slide on the connecting rod 18, the rotating frame 4 will overcome part of the elastic force of the third elastic member 20 under the external force generated by the protrusion and slightly lift up, thereby preventing the equipment from being damaged due to excessive stress, and the protrusion can be gradually polished or eliminated. Under the elastic force of the third elastic member 20, the connecting block 19 drives the rotating frame 4 to gradually reset, so that the rough polishing wheel 5 or the fine polishing wheel 6 returns to the normal working position to continue the polishing operation. When it is necessary to adjust the contact force of the rough polishing wheel 5 or the fine polishing wheel 6 on the sheet metal part 1, by screwing the fastener 21 downward, the fastener 21 gradually compresses the third elastic member 20, changes the deformation of the third elastic member 20, thereby increasing or reducing its elastic force on the connecting block 19, and then realizing precise control of the contact force of the rough polishing wheel 5 or the fine polishing wheel 6 on the sheet metal part 1.

[0087] Furthermore, it also includes a sliding frame 22, which is laterally slidably arranged on the frame 2, and the workbench 3 is longitudinally slidably arranged on the sliding frame 22; one end of the connecting rod 23 is hingedly arranged on the workbench 3; the eccentric wheel 24 is eccentrically rotatably arranged on the sliding frame 22, and the other end of the connecting rod 23 is hingedly arranged on the eccentric end of the eccentric wheel 24, and the rotation of the eccentric wheel 24 drives the workbench 3 to slide reciprocatingly longitudinally on the sliding frame 22.

[0088] In this embodiment, a transverse guide rail is installed on the frame 2, and the sliding frame 22 is installed on the guide rail through a matching sliding structure. A longitudinal guide rail is set on the sliding frame 22, and the workbench 3 is connected to the longitudinal guide rail through a corresponding sliding connection, so that the workbench 3 can smoothly slide longitudinally on the sliding frame 22. One end of the connecting rod 23 is connected to the eccentric end of the eccentric wheel 24 through a hinge at a suitable position on one side of the workbench 3, and the other end of the connecting rod 23 is connected to the eccentric end of the eccentric wheel 24 through a hinge. The eccentric wheel 24 is eccentrically installed on the sliding frame 22 through a high-precision bearing. When the motor driving the eccentric wheel 24 to rotate is started, the eccentric wheel 24 begins to rotate eccentrically around its axis. As the eccentric wheel 24 rotates, its eccentric end will drive the connecting rod 23 to reciprocate, and the connecting rod 23 then pushes the workbench 3 to reciprocate longitudinally on the longitudinal guide rail of the sliding frame 22.

[0089] The advantage is that the design of the eccentric wheel 24 and the linkage rod 23 realizes the reciprocating longitudinal sliding function of the workbench 3, providing longitudinal relative movement for the sheet metal part 1 during the polishing process. This function effectively avoids the problem of partial over-polishing of the sheet metal part 1 caused by the coarse polishing wheel 5 or the fine polishing wheel 6 continuously polishing at the same position.

[0090] Furthermore, it also includes a rack 25, which is arranged on the sliding frame 22; a gear 26 is rotatably arranged on the frame 2, the rack 25 is meshed with the gear 26, and after the gear 26 rotates, it drives the sliding frame 22 to slide horizontally in the frame 2.

[0091] In this embodiment, a rack 25 is installed in the transverse direction on one side of the sliding frame 22. A driving device is provided on the frame 2, and a gear 26 is installed at the driving end thereof, so that the gear 26 is in a meshing state with the rack 25. When the power device (such as a combination of a motor and a reducer) that drives the gear 26 to rotate is started, the rotation of the gear 26 will be converted into a transverse linear motion of the rack 25, thereby driving the sliding frame 22 to slide transversely on the transverse guide rail of the frame 2.

[0092] The advantage is that the transmission structure of the rack 25 and the gear 26 is used to realize the lateral sliding of the slide frame 22, which is combined with the longitudinal sliding of the workbench 3, so that the sheet metal part 1 can achieve comprehensive and uniform two-dimensional planar movement during the polishing process.
