Description

Technical Field

[0001] This invention relates to the technical field of processing equipment, and more particularly to a floating grinding device. Background Technology

[0002] Continuous casting and rolling is one of the important methods for producing copper wire rods for electrical applications. During the production process, the casting wheel, as an important component for the crystallization of molten copper, needs to be mechanically sandblasted regularly to remove carbon black scale. Since the sandblasting process makes the surface of the casting wheel rough, it needs to be polished manually to achieve reuse and ensure the quality of the copper wire rod.

[0003] The current method of grinding cast wheels is mainly manual, which has the following problems: First, it is labor-intensive and inefficient for workers; second, manual grinding creates a dusty and unsanitary environment that affects their health; and third, manual grinding results in uneven surfaces and poor grinding effects. Summary of the Invention

[0004] In view of the above-mentioned problems in existing cast wheel grinding, the aim is to provide a floating grinding device with low labor cost, high efficiency and excellent grinding effect.

[0005] The specific technical solution is as follows:

[0006] A floating grinding device includes a grinding mechanism. The grinding mechanism includes a mounting body and a grinding wheel mounted on the mounting body and rotatable. The grinding mechanism is used to grind the inner wall of a groove on the outer circumference of a casting wheel and coaxially arranged with the casting wheel.

[0026] As a further improvement and optimization of this solution, the guide component includes:

[0027] A guide floating frame is rotatably mounted with multiple rollers, the axes of which are parallel to the axis of the casting wheel and in contact with the outer circumferential surface of the casting wheel. The guide floating frame is fixed to the bottom of the transverse floating frame.

[0028] The travel frame is connected to the lateral adjustment member and moves laterally through the lateral adjustment member. Several fourth elastic elements are provided between the travel frame and the guide floating frame.

[0033] A driving component, which is connected to the lifting frame, is used to drive the lifting frame to move longitudinally.

[0036] A drive component is mounted on the second mounting bracket and connected to the transverse moving bracket for driving the transverse moving bracket to move laterally.

[0037] The positive effects of the above technical solution compared with the existing technology are:

[0038] (1) In this invention, the grinding angle of the grinding wheel is adjusted by the angle adjustment mechanism to grind the bottom of the groove, the top side wall of the groove and the bottom side wall of the groove. During the grinding process, the floating mechanism enables the grinding wheel to automatically float and adjust, so that the grinding wheel always fits the grinding surface of the groove during the grinding process. The degree of manual intervention in the processing is low, which not only greatly reduces labor costs and improves processing efficiency, but also improves the uniformity of grinding and improves the grinding effect through mechanical automatic grinding.

[0039] (2) During the grinding process, the present invention ensures that the grinding wheel is always in contact with the top sidewall of the groove under the elastic force of several second elastic elements during the grinding process of the top sidewall of the groove, and under the action of several first elastic elements during the grinding process of the bottom sidewall of the groove, the grinding wheel is always in contact with the bottom sidewall of the groove under the action of several first elastic elements during the grinding process of the groove bottom, thereby realizing the automatic floating adjustment of the grinding wheel during the grinding process to adapt to the grinding degree of the inner wall of the groove, which greatly improves the uniformity and grinding effect of the grinding.

[0040] (3) In this invention, before grinding the cast wheel, the guide component is driven to move laterally by the lateral adjustment component so that the roller contacts the outer circumferential surface of the cast wheel and rotates synchronously with the cast wheel. At this time, the outer circumferential surface of the grinding wheel contacts the bottom of the groove, and the third elastic element and the fourth elastic element are in a compressed energy storage state. On the one hand, the lateral position of the grinding wheel in the groove is accurately positioned by the cooperation of the roller and the cast wheel, without the need for manual sensory adjustment, which improves the processing efficiency and grinding effect. On the other hand, since the cast wheel itself or during the rotation process has an eccentricity, the fourth elastic element can avoid the influence of the eccentricity on the grinding effect. At the same time, when the grinding wheel grinds the inner wall of the groove, causing the cast wheel to wobble laterally, the grinding wheel can wobble synchronously with the cast wheel under the elastic force of the fourth elastic element, which effectively avoids the influence of the cast wheel wobble on the grinding of the cast wheel, and further improves the grinding uniformity and grinding effect.

[0041] (4) The present invention provides a dust collection mechanism on the grinding mechanism, which can remove dust in real time while grinding, improve the working environment and avoid the impact of dust on the grinding effect. Attached Figure Description

Figure 2 This is a diagram showing the fit between the floating mechanism and the longitudinal adjustment component of a floating grinding device according to the present invention. Figure 3 This is a schematic diagram of the structure of a floating polishing device according to the present invention. Figure 4 This is a schematic diagram of the longitudinal floating component of a floating grinding device according to the present invention. Figure 5 This is a schematic diagram of the structure of the locking plate of a floating grinding device according to the present invention, as shown below. Figures 1 to 5The diagram illustrates a preferred embodiment of a floating polishing device, comprising a polishing mechanism 2. The polishing mechanism 2 includes a mounting body 22 and a rotatable polishing wheel 21 mounted on the mounting body 22. The polishing mechanism 2 is used to polish the inner wall of a groove 11 located on the outer circumference of the casting wheel 1 and coaxially arranged with the casting wheel 1. The groove 11 is flared, and both side walls of the groove 11 are inclined surfaces. The polishing device further includes a stroke adjustment mechanism 3, an angle adjustment mechanism 6, a floating mechanism 4, and a dust collection mechanism 5. The stroke adjustment mechanism 3 is used to adjust the polishing... The position of the grinding wheel 21 is adjusted so that the grinding wheel 21 moves to the grinding surface of the wheel groove 11. The angle adjustment mechanism 6 is used to adjust the grinding angle of the grinding wheel 21. When grinding the side wall of the wheel groove 11, the grinding wheel 21 is parallel to the side wall of the wheel groove 11. When grinding the bottom of the wheel groove 11, the axis of the grinding wheel 21 is set parallel to the axis of the casting wheel 1. The floating mechanism 4 is used to drive the grinding wheel 21 to automatically float and adjust so that the grinding wheel 21 contacts the grinding surface of the wheel groove 11. The dust collection mechanism 5 is provided on the grinding mechanism 2 and is used to suck up and collect the dust from the grinding wheel 21.

[0057] In this embodiment, when grinding the top side wall of the groove 11 of the casting wheel 1, the stroke adjustment mechanism 3 drives the grinding wheel 21 to move to the top side wall of the groove 11. The grinding angle of the grinding wheel 21 is adjusted by the angle adjustment mechanism 6, and the top end face of the grinding wheel 21 is parallel to the top side wall of the groove 11. At the same time, the floating mechanism 4 makes the grinding wheel 21 float and makes the grinding wheel 21 and the top side wall of the groove 11 close to each other. Then the casting wheel 1 rotates and the grinding wheel 21 rotates. Under the rotation of the casting wheel 1, the grinding wheel 21 grinds the top side wall of the groove 11 evenly.

[0058] When grinding the bottom sidewall of the groove 11, the grinding wheel 21 is moved to the bottom sidewall of the groove 11, the grinding angle of the grinding wheel 21 is adjusted and the bottom end face of the grinding wheel 21 is made parallel to the bottom sidewall of the groove 11. The floating mechanism 4 makes the grinding wheel 21 always fit against the bottom sidewall of the groove 11 and grinds the bottom sidewall evenly.

[0059] When grinding the bottom of the groove 11, the grinding angle of the grinding wheel 21 is adjusted again so that the axis of the grinding wheel 21 is parallel to the axis of the casting wheel 1. Under the drive of the floating mechanism 4, the outer circumferential surface of the grinding wheel 21 is always in contact with the bottom of the groove 11. The stroke adjustment mechanism 3 drives the grinding wheel 21 to move slowly in the longitudinal direction (from top to bottom or from bottom to top) and grinds the bottom of the groove 11 evenly.

[0060] In this embodiment, the grinding angle of the grinding wheel 21 is adjusted by the angle adjustment mechanism 6 to grind the bottom of the groove 11, the top sidewall of the groove 11, and the bottom sidewall of the groove 11. During the grinding process, the floating mechanism 4 enables the grinding wheel 21 to automatically float and adjust, so that the grinding wheel 21 always keeps in contact with the grinding surface of the groove 11. The degree of manual intervention in the processing is low, which not only greatly reduces labor costs and improves processing efficiency, but also improves the uniformity of grinding and the grinding effect through automatic mechanical grinding.

[0061] The present invention provides a dust collection mechanism 5 on the grinding mechanism 2, which can remove dust in real time while grinding, improve the working environment and avoid the impact of dust on the grinding effect.

[0062] Furthermore, as a preferred embodiment, the dust collection mechanism 5 includes a dust collection groove 52 arranged around the outer circumference of the grinding wheel 21 for adsorbing grinding dust, and a collection box 51 provided on the mounting body 22 for collecting the dust adsorbed by the dust collection groove 52.

[0063] Furthermore, as a preferred embodiment, the floating mechanism 4 includes a longitudinal floating component 41 and a transverse floating component 42. The grinding wheel 21 is mounted on the longitudinal floating component 41. The longitudinal floating component 41 is used to drive the grinding wheel 21 to float longitudinally so that the grinding wheel 21 contacts the side wall of the wheel groove 11. The transverse floating component 42 is used to drive the grinding wheel 21 to float laterally so that the grinding wheel 21 contacts the bottom of the wheel groove 11.

[0064] In this embodiment, when the grinding wheel 21 grinds the top sidewall and the bottom sidewall of the groove 11, the longitudinal floating component 41 acts on the grinding wheel 21. When grinding the sidewall of the groove 11, the top end face / bottom end face of the grinding wheel 21 is always in contact with the grinding surface of the groove 11. When grinding the bottom of the groove 11, the transverse floating component 42 acts on the grinding wheel 21 and makes the outer circumferential surface of the grinding wheel 21 always in contact with the bottom of the groove 11.

[0065] Furthermore, in a preferred embodiment, the angle adjustment mechanism 6 includes an adjustment frame 61 and a locking assembly 62. The adjustment frame 61 is rotatably mounted, and the grinding wheel 21 is mounted on the adjustment frame 61 via a longitudinal floating assembly 41. The adjustment frame 61 is mounted on the stroke adjustment mechanism 3 via the locking assembly 62 and locked in place by the locking assembly 62 to fix the grinding angle of the grinding wheel 21. The adjustment frame 61 moves via the stroke adjustment mechanism 3 to move the grinding wheel 21 to the grinding surface of the wheel groove 11.

[0066] In this embodiment, when adjusting the grinding angle of the grinding wheel 21, the rotating adjustment frame 61 makes the grinding wheel 21 rotate synchronously through the longitudinal floating component 41 so that the grinding wheel 21 adapts to the grinding surface of the wheel groove 11. Then, the adjustment frame 61 is locked and fixed by the locking component 62 to complete the angle adjustment.

[0067] Furthermore, in a preferred embodiment, the longitudinal floating assembly 41 includes a longitudinal floating frame 411 and at least two longitudinal guide rods 413. A plurality of first elastic elements 412 are provided between the top of the longitudinal floating frame 411 and the adjustment frame 61, and a plurality of second elastic elements 414 are provided between the bottom of the longitudinal floating frame 411 and the adjustment frame 61. An installation body 22 is mounted on the longitudinal floating frame 411, and a driving element 23 is provided on the installation body 22. The output end of the driving element 23 is connected to the grinding wheel 21 to drive the grinding wheel 21 to rotate. The two ends of the two longitudinal guide rods 413 are fixed on the adjustment frame 61, and the two longitudinal guide rods 413 pass through the longitudinal floating frame 411 and form a sliding guide engagement with the longitudinal floating frame 411.

[0068] Preferably, the driving component 23 is a motor, which is positioned downwards and has a handle on its top.

[0069] In this embodiment, when the longitudinal floating component 41 acts on the grinding wheel 21, the grinding wheel 21 grinds the top sidewall of the groove 11. The grinding wheel 21 is angled and parallel to the top sidewall of the groove 11. The stroke adjustment mechanism 3 drives the grinding wheel 21 to move upward. The top sidewall of the groove 11 acts on the grinding wheel 21 and causes the longitudinal floating frame 411 to press down the second elastic member 414, so that the second elastic member 414 is in a compressed energy storage state. During the grinding process of the top sidewall of the groove 11, the elastic potential energy of the second elastic member 414 acts on the grinding wheel 21 through the longitudinal floating frame 411, so that the grinding wheel 21 is always in close contact with the top sidewall of the groove 11.

[0070] When grinding the bottom sidewall of the wheel groove 11, repeat the above operation. After the angle of the grinding wheel 21 is adjusted, the stroke adjustment mechanism 3 drives the grinding wheel 21 to move downward. The bottom sidewall of the wheel groove 11 acts on the grinding wheel 21 and causes the longitudinal floating frame 411 to compress the first elastic element 412. Under the elastic potential energy of the first elastic element 412, the grinding wheel 21 is always in contact with the bottom sidewall of the wheel groove 11 during the grinding process.

[0071] In this embodiment, during the grinding process, when grinding the top sidewall of the wheel groove 11, the grinding wheel 21 is kept in contact with the top sidewall of the wheel groove 11 under the elastic force of several second elastic elements 414. When grinding the bottom sidewall of the wheel groove 11, the grinding wheel 21 is kept in contact with the bottom sidewall of the wheel groove 11 under the action of several first elastic elements 412. This achieves automatic floating adjustment of the grinding wheel 21 during the grinding process to adapt to the grinding degree of the sidewall of the wheel groove 11, greatly improving the uniformity and grinding effect of the grinding.

[0072] Furthermore, as a preferred embodiment, the stroke adjustment mechanism 3 includes a longitudinal adjustment component 31 and a lateral adjustment component 32. The longitudinal adjustment component 31 is connected to the locking component 62 and is used to drive the adjustment frame 61 to move longitudinally so that the grinding wheel 21 can be adjusted longitudinally. The lateral adjustment component 32 is connected to the longitudinal floating component 41 through the lateral floating component 42 and drives the adjustment frame 61 to move laterally so that the grinding wheel 21 can be adjusted laterally.

[0073] Furthermore, as a preferred embodiment, the lateral floating component 42 includes: a lateral floating frame 421 and a plurality of lateral guide rods 423. The lateral floating frame 421 is connected to the lateral adjustment component 32 and moves laterally through the lateral adjustment component 32. A plurality of third elastic members 422 are provided between the lateral floating frame 421 and the longitudinal adjustment component 31. One end of the plurality of lateral guide rods 423 is fixedly installed on the longitudinal adjustment component 31, and the other end passes through the lateral floating frame 421.

[0074] In this embodiment, when the grinding wheel 21 grinds the bottom of the groove 11, the grinding angle of the grinding wheel 21 is adjusted and the axis of the grinding wheel 21 is made parallel to the axis of the casting wheel 1. The lateral adjustment component 32 drives the grinding wheel 21 to move towards the bottom of the groove. The bottom of the groove 11 acts on the outer circumferential surface of the grinding wheel 21 with a radially outward supporting force. Under the action of this supporting force, the third elastic element 422 is in a compressed and energy-storing state through the grinding wheel 21. During the grinding process of the grinding wheel 21 on the bottom of the groove 11, the elastic potential energy of the third elastic element 422 always drives the outer circumferential surface of the grinding wheel 21 to elastically contact the bottom of the groove 11.

[0075] In this embodiment, during the grinding process, when grinding the top sidewall of the wheel groove 11, the grinding wheel 21 is always in contact with the top sidewall of the wheel groove 11 under the elastic force of several second elastic elements 414. When grinding the bottom sidewall of the wheel groove 11, the grinding wheel 21 is always in contact with the bottom sidewall of the wheel groove 11 under the action of several first elastic elements 412. When grinding the bottom of the wheel groove 11, the grinding wheel 21 is always in elastic contact with the bottom of the wheel groove 11 under the action of several third elastic elements 422. This achieves automatic floating adjustment of the grinding wheel 21 during the grinding process to adapt to the grinding degree of the inner wall of the wheel groove 11, greatly improving the uniformity and grinding effect of the grinding.

[0076] Furthermore, as a preferred embodiment, the lateral adjustment assembly 32 includes a guide member 321 and a lateral adjustment member 322. The guide member 321 is installed at the bottom of the lateral floating frame 421 and is used to position the lateral position of the grinding wheel 21. The lateral adjustment member 322 is installed at the bottom of the guide member 321 and is used to drive the lateral floating frame 421 to move laterally so that the grinding wheel 21 can be adjusted in lateral position.

[0077] Furthermore, in a preferred embodiment, the guide member 321 includes: a guide floating frame 3215, a stroke frame 3213, and a plurality of guide rods 3214. The guide floating frame 3215 is rotatably mounted with a plurality of rollers 3211, and the axes of the plurality of rollers 3211 are arranged parallel to the axis of the casting wheel 1 and in contact with the outer circumferential surface of the casting wheel 1. The guide floating frame 3215 is fixed to the bottom of the transverse floating frame 421. The stroke frame 3213 is connected to the transverse adjustment member 322 and moves laterally through the transverse adjustment member 322. A plurality of fourth elastic members 3212 are provided between the stroke frame 3213 and the guide floating frame 3215. A plurality of guide rods 3214 are provided between the guide floating frame 3215 and the stroke frame 3213, and one end of the plurality of guide rods 3214 is fixed to the guide floating frame 3215 and the other end passes through the stroke frame 3213.

[0078] In this embodiment, before grinding the casting wheel 1, the guide member 321 is driven to move laterally by the lateral adjustment member 322 so that the roller 3211 contacts the outer circumferential surface of the casting wheel 1 and rotates synchronously with the casting wheel 1. At this time, the outer circumferential surface of the grinding wheel 21 contacts the bottom of the groove 11, and the third elastic member 422 and the fourth elastic member 3212 are both in a compressed and energy-storing state. On the one hand, the lateral position of the grinding wheel 21 in the groove 11 is accurately positioned by the cooperation between the roller 3211 and the casting wheel 1, without the need for manual sensory adjustment. The test improves processing efficiency and grinding effect. On the other hand, due to the eccentricity of the casting wheel itself or during the rotation process, the fourth elastic element can avoid the influence of eccentricity on the grinding effect. At the same time, when the grinding wheel 21 grinds the inner wall of the wheel groove 11, causing the casting wheel 1 to wobble laterally under the force of the fourth elastic element 3212, the grinding wheel 21 and the casting wheel 1 can wobble synchronously, effectively avoiding the influence of the casting wheel 1 wobble on the grinding of the casting wheel 1, and further improving the grinding uniformity and grinding effect.

[0079] Furthermore, in a preferred embodiment, the longitudinal adjustment assembly 31 includes: a lifting frame 311, a first mounting frame 312, and a driving component 313. The lifting frame 311 is located on the side of the adjustment frame 61 away from the casting wheel 1, and the locking assembly 62 is fixedly installed on the lifting frame 311. The first mounting frame 312 is located between the lifting frame 311 and the transverse floating frame 421 and is vertically slidably installed on the first mounting frame 312. Several third elastic members 422 are located between the first mounting frame 312 and the transverse floating frame 421. One end of several transverse guide rods 423 is fixed to the first mounting frame 312, and the other end passes through the transverse floating frame 421. The driving component 313 is connected to the lifting frame 311 and is used to drive the lifting frame 311 to move longitudinally.

[0080] In this embodiment, when the longitudinal adjustment component 31 is working, the driving component 313 drives the lifting frame 311 to move longitudinally. Since the adjustment frame 61 is installed on the lifting frame 311 through the locking component 62, the grinding wheel 21 moves synchronously with the lifting frame 311.

[0081] Specifically, the driving component 313 includes a first handle 3131 and a first lead screw 3132. The first lead screw is vertically arranged and rotatably mounted on the first mounting bracket 312. The lifting bracket 311 is threaded onto the outside of the first lead screw 3132. The first handle 3131 is coaxially fixed to the top of the first lead screw 3132. When the first handle 3131 is rotated, the first lead screw 3132 moves synchronously. The threaded engagement between the first lead screw 3132 and the lifting bracket 311 causes the lifting bracket 311 to move longitudinally, thereby driving the grinding wheel 21 to move longitudinally.

[0082] Furthermore, as a preferred embodiment, the lateral adjustment member 322 includes: a second mounting bracket 3321 and a driving component 3223. The lateral moving bracket 3322 is slidably mounted on the top of the second mounting bracket 3321, and the lateral moving bracket 3322 and the second mounting bracket 3321 form a lateral sliding guide engagement. The travel bracket 3213 is fixed on the lateral moving bracket 3322. The driving component 3223 is mounted on the second mounting bracket 3321 and connected to the lateral moving bracket 3322 for driving the lateral moving bracket 3322 to move laterally.

[0083] Preferably, the driving component 3223 includes a second handle 3223A and a second lead screw 3223B.
