Description

Technical Field

[0001] This invention relates to the field of grinding machine technology, and in particular to a quick assembly structure for grinding machine modules. Background Technology

[0002] Grinding machines are crucial in the grinding and processing of stainless steel strips, and their grinding discs are the core consumables that directly participate in the grinding process. During the continuous grinding production of stainless steel strips, the grinding discs are subjected to high loads and wear continuously, and must be disassembled and replaced regularly to maintain stable grinding accuracy and surface quality.

[0003] In existing grinding machines, the grinding disc and the drive mechanism are connected by a splicing structure. Because the grinding disc transmits large torques, rotates at high speeds, and is subjected to complex loads, if the splicing structure relies on only a single connection point at the center of rotation, stress concentration can easily occur under alternating stress and impact, leading to fatigue damage or even fracture at the connection point. To avoid damage to the splicing structure and improve connection rigidity and durability, the industry generally adopts a design scheme with multiple connection points evenly distributed around the center of rotation, distributing the stress to ensure operational reliability.

[0004] However, this multi-connection-point structure around the axis also brings significant drawbacks. Each time the grinding disc is replaced, operators must disassemble each fastener or locking component distributed at each connection point, then install, tighten, and verify them one by one after the new grinding disc is in place—a very cumbersome assembly process. This problem is further amplified when applied to large grinding machines—these machines often require the simultaneous assembly of numerous grinding discs, resulting in a massive workload for disassembly and reassembly. This leads to long downtime, slow relocation and recovery operations, severely restricting continuous construction capabilities and reducing overall output efficiency. Summary of the Invention

[0005] This invention provides a quick assembly structure for grinding machine modules that can ensure connection strength and quickly complete splicing and disassembly, aiming to solve the defects of the prior art pointed out in the background art above.

[0007] Preferably, the structure further includes: a first return spring disposed within the mounting plate, the two ends of which are fixed to the mounting plate and the locking block respectively, for assisting the locking block in radial reset, and each locking block is correspondingly provided with a first return spring; a mounting ring fixedly connected within the mounting plate and coaxial with it, the rotating disk slidingly engaging with the mounting ring; at least two second return springs sleeved on the mounting ring, the two ends of each second return spring being fixed to the mounting ring and the rotating disk respectively, for resetting the rotating disk to its initial rotation position; a protrusion fixedly connected to the periphery of the rotating disk; and a groove provided on the side wall of the mounting plate for the protrusion to move, allowing the operator to manipulate the rotating disk to rotate by moving the protrusion from the outside.

[0008] Preferably, the structure further includes a removable rubber cap located at the channel for sealing and protecting the interior of the channel.

[0009] Preferably, the structure further includes: a limiting strip slidably connected within the mounting plate, the moving direction of the limiting strip being perpendicular to the rotation plane of the rotating disk; the limiting strip being located on the moving trajectory line of the protrusion, and its own lifting movement enabling it to limit and block the protrusion; a third return spring sleeved on the limiting strip, its two ends being fixedly connected to the limiting strip and the mounting plate respectively, for driving the limiting strip to return axially; a push block slidably connected within the mounting plate, the push block being located above the insertion hole, and when the connecting block is inserted into the insertion hole, the connecting block can contact the push block and push the push block to move; a double wedge block frame slidably connected within the mounting plate, its two ends being in contact with the limiting strip and the push block respectively, so as to convert the linear movement of the push block into the linear movement of the limiting strip; a fourth return spring sleeved on the sliding shaft of the double wedge block frame, its two ends being fixedly connected to the double wedge block frame and the mounting plate respectively, for driving the double wedge block frame to return axially; and a roller rotatably connected to the bottom of the limiting strip.

[0010] Preferably, the top surface of the grinding disc has an annular groove, which is arranged around the rotation axis of the grinding disc; the structure also includes: a fixing ring slidably connected to the bottom surface of the mounting plate, the fixing ring being positioned corresponding to the position of the annular groove, and the height of the fixing ring being greater than the depth of the annular groove; and a pressure spring fixedly connected between the mounting plate and the fixing ring, the pressure spring being used to apply elastic pressure to the fixing ring in the direction of the grinding disc.

[0011] Preferably, each connecting block is rotatably connected to the grinding disc and can be rotated into the grinding disc, with the upper surface of the connecting block flush with the top surface of the grinding disc after being retracted. The structure also includes: a gear ring fixedly connected to the rotating shaft of each connecting block; a return torsion spring fixedly connected between each connecting block and the grinding disc, the return torsion spring keeping the connecting block retracted into the grinding disc in its natural state; and a pusher slidably connected to the grinding disc along the radial direction of the grinding disc, with each connecting block corresponding to a set of pushers; each pusher is provided with a set of teeth, and each pusher interacts with the grinding disc via the teeth. The gear ring on the connecting block should mesh to convert the linear movement of the pusher into the rotational movement of the connecting block; the control disk is rotatably connected to the grinding disc, and the control disk is coaxial with the grinding disc and can act on each pusher; the control disk has an arc segment and a straight segment corresponding to each pusher; the arc segment protrudes outward from the outer periphery of the control disk, and the straight segment is located at the outermost end of the arc segment and is perpendicular to the radial direction of the control disk.

[0012] Preferably, the structure further includes: an inner angle shaft fixedly connected to the center of the control disk shaft, the top surface of the inner angle shaft being flush with the top surface of the grinding disk.

There are two marking marks. When the inner angle shaft rotates to the point where the indicator mark corresponds to the two marking marks, it indicates that the connecting block is in a fully extended state and a retracted state, respectively.

[0014] The beneficial effects of this invention are: by synchronously linking all locking blocks with a single rotating disc, this invention simplifies the traditional operation of disassembling and assembling multiple connection points one by one into a single action of simply moving the protrusion, which significantly reduces the steps and time spent on replacing the grinding disc; especially in the case of a large grinding machine with a large number of grinding discs, it greatly shortens the downtime of the grinding machine and improves the efficiency of continuous operation.

Detailed Implementation

[0030] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0031] Example: A quick-assembly structure for a grinding machine module, such as... Figures 1-6 As shown, the structure includes: a drive shaft 101 of a grinding machine, a mounting plate 102 fixedly mounted on the end of the drive shaft 101, and a grinding disc 103 detachably mounted on the bottom surface of the mounting plate 102; the structure also includes: four connecting blocks 104 disposed on the top surface of the grinding disc 103, each connecting block 104 being evenly arranged circumferentially along the rotation axis of the grinding disc 103; each connecting block 104 having a locking hole 1041; the bottom surface of the mounting plate 102 having insertion holes corresponding to the positions of each connecting block 104, after the connecting block 104 is inserted into the insertion hole, the top surface of the grinding disc 103 is in contact with the bottom surface of the mounting plate 102; and locking blocks 105 slidably mounted in the mounting plate 102 corresponding to each insertion hole, each locking block 105 being slidably mounted along the bottom surface of the mounting plate 102. The mounting plate 102 moves radially; the locking block 105 is provided with a locking shaft 1501 on the side facing the connecting block 104. The locking shaft 1501 is used to insert into the locking hole 1041 on the connecting block 104, thereby preventing the grinding disc 103 from disengaging from the mounting plate 102 by restricting the axial movement of the connecting block 104; a rotating plate 107 is rotatably mounted in the mounting plate 102 and coaxial with it; a guide groove 1071 is provided on the rotating plate 107 corresponding to each locking block 105, and a guide shaft 1052 is fixed at the bottom of each locking block 105. Each guide shaft 1052 slides in the corresponding guide groove 1071, so that when the rotating plate 107 rotates, it can synchronously drive all locking blocks 105 to move radially along the mounting plate 102.

[0032] like Figures 1-6As shown, this structure also includes: a first return spring 106 disposed within the mounting plate 102, with both ends of the first return spring 106 fixed to the mounting plate 102 and the locking block 105 respectively, for assisting the locking block 105 in radial reset; each locking block 105 is correspondingly provided with a first return spring 106; a mounting ring 108 fixedly installed within the mounting plate 102 and coaxial with it, the rotating disk 107 slidingly engaging with the mounting ring 108; and at least two second return springs 109 sleeved on the mounting ring 108, with both ends of each second return spring 109 fixed to the mounting plate 102 and the locking block 105 respectively. Mounting ring 108 and rotating disk 107 are used to reset rotating disk 107 to its initial rotation position; protrusions 110 are fixedly installed on the periphery of rotating disk 107; the side wall of mounting disk 102 is provided with a channel 111 for moving protrusions 110, and the operator can move protrusions 110 from the outside to control the rotation of rotating disk 107; a detachable rubber cover 112 is provided at the channel 111 to seal and protect the inside of the channel 111; the rubber cover 112 is preferably made of deformable material, one end of which is fixed to the channel 111, and the whole is sealed at the channel 111 by a plug-in method.

[0033] When the grinding disc 103 needs to be installed, the operator first opens the rubber cover 112 and moves the protrusion 110 along the groove 111, causing the rotating disc 107 to rotate against the force of the second return spring 109. At this time, utilizing the cooperation between the guide groove 1071 and the guide shaft 1052, the rotating disc 107 synchronously drives all the locking blocks 105 to move radially away from the axis, making room for the insertion of the connecting blocks 104, and the first return spring 106 stores energy accordingly. Maintaining this state, the grinding disc 103 is moved to the bottom of the mounting plate 102, so that the connecting blocks 104 on its top surface are aligned and inserted into the corresponding insertion holes on the bottom surface of the mounting plate 102, until the top surface of the grinding disc 103 is in contact with the bottom surface of the mounting plate 102. Subsequently, the protrusion 110 is released, and the elastic restoring force of the second return spring 109 drives the rotating disk 107 to rotate in the opposite direction. The rotating disk 107, with the help of the guide groove 1071, drives all the locking blocks 105 to return to their radial positions simultaneously. At the same time, the first return spring 106 also assists in pushing the locking blocks 105 to ensure that the locking shaft 1501 is accurately inserted into the locking hole 1041 of the already positioned connecting block 104, thereby completing the axial locking of the grinding disc 103 and making the grinding disc 103 stably assembled on the bottom of the mounting plate 102. When it is necessary to disassemble the grinding disc 103, the protrusion 110 is moved again to make all the locking blocks 105 move outward simultaneously and the locking shaft 1501 disengage from the locking hole 1041, so that the connecting block 104 can be freely pulled out and the grinding disc 103 can be easily removed.

[0034] This structure uses a single rotating disk 107 to synchronously link all locking blocks 105, simplifying the traditional multi-connection point disassembly and assembly operation into a single action of simply moving the protrusion 110, significantly reducing the steps and time required to replace the grinding disc 103; especially in the case of a large number of grinding discs 103 in a large grinding machine, it greatly shortens the downtime of the grinding machine and improves the efficiency of continuous operation.

[0035] like Figure 3 , Figure 6 and Figure 7 As shown, this structure also includes: a limiting strip 201 slidably installed in the mounting plate 102, the moving direction of the limiting strip 201 being perpendicular to the rotation plane of the rotating plate 107; the limiting strip 201 being located on the moving trajectory line of the protrusion 110, and being able to limit and block the protrusion 110 through its own lifting and lowering movement; a slot 2011 being provided on the upper part of the limiting strip 201; a third return spring 202 sleeved on the limiting strip 201, the two ends of which are respectively fixedly connected to the limiting strip 201 and the mounting plate 102, for driving the limiting strip 201 to return to its axial position; and a push block 203 slidably installed in the mounting plate 102, the push block 203 being located above the insertion hole, and when the connecting block 104 is inserted into the insertion hole, the connecting block 104 can contact the push block 203 and... Pushing block 203 moves; a double wedge block frame 204 slidably installed in mounting plate 102 has two wedge-shaped parts on its sliding shaft, forming a first inclined surface 2041 and a second inclined surface 2042 respectively; wherein, the first inclined surface 2041 is used to make contact with the slot 2011 on the limiting strip 201, and the second inclined surface 2042 is used to make contact with the push block 203; a fourth return spring 205 sleeved on the sliding shaft of the double wedge block frame 204, with its two ends fixedly connected to the double wedge block frame 204 and the mounting plate 102 respectively, is used to drive the double wedge block frame 204 to return to its axial position; a roller 206 rotatably installed at the bottom of the limiting strip 201 is used to convert the contact between the limiting strip 201 and the protrusion 110 into rolling contact to reduce frictional resistance.

[0036] When the operator moves the protrusion 110 to rotate the rotating disk 107, causing the locking block 105 to retract to the unlocked position, the protrusion 110 moves away from directly below the limiting bar 201. At this time, the elastic restoring force of the third return spring 202 pushes the limiting bar 201 downward, causing the limiting bar 201 to enter the reset path of the protrusion 110, preventing the protrusion 110 from rotating back, thereby locking the locking block 105 in the retracted state. In this state, the connecting block 104 can freely enter and exit the socket, and the operator does not need to continuously operate the protrusion 110.

[0037] When installing the new grinding disc 103, during the insertion of the connecting block 104 into the socket, the upper end of the connecting block 104 contacts the push block 203 and pushes the push block 203 to move synchronously. After the push block 203 moves, it contacts and engages with the second inclined surface 2042 of the double wedge block frame 204. The inclined surface force pushes the double wedge block frame 204 to move axially, and the fourth return spring 205 is compressed accordingly. The axial movement of the double wedge block frame 204 causes its first inclined surface 2041 to contact and engage with the slot 2011 on the limiting strip 201. The inclined surface pressing force forces the limiting strip 201 to move upward, the third return spring 202 is compressed, and the limiting strip 201 releases its blocking and limiting effect on the protrusion 110. At this point, under the combined action of the elastic restoring force of the first return spring 106 and the second return spring 109, the rotating disk 107 and the locking block 105 automatically reset, and the locking shaft 1501 is inserted into the locking hole 1041 of the connecting block 104, thus completing the automatic locking of the grinding disk 103.

[0038] Therefore, this structure can automatically maintain the retracted state of the locking block 105 and release it upon insertion, so that when the grinding disc 103 is disassembled, the locking block 105 is automatically locked in the retracted position, so that the operator does not need to operate the protrusion 110 simultaneously during the next installation, but only needs to insert the grinding disc 103 to trigger automatic locking.

[0039] This structure further simplifies the complex disassembly and assembly process with multiple connection points into a single insertion action, thereby reducing operational intensity and shortening replacement time. It is especially suitable for large grinding machines with a large number of grinding discs 103 and frequent replacements.

[0040] like Figure 3 , Figure 8 and Figure 9 As shown, the top surface of the grinding disc 103 is provided with an annular groove 301, which surrounds the rotation axis of the grinding disc 103. The structure also includes: a fixing ring 302 slidably mounted on the bottom surface of the mounting plate 102, the fixing ring 302 being positioned corresponding to the position of the annular groove 301, and the height of the fixing ring 302 being greater than the depth of the annular groove 301; and a pressure spring 303 fixedly mounted between the mounting plate 102 and the fixing ring 302, the pressure spring 303 being used to apply elastic pressure to the fixing ring 302 in the direction of the grinding disc 103.

[0041] After the grinding disc 103 is assembled onto the mounting plate 102 and locked in place, the retaining ring 302 is driven by the elastic force of the pressure spring 303 into the annular groove 301, at which point the pressure spring 303 is in a compressed state. The cooperation between the retaining ring 302 and the annular groove 301 forms an annular closed barrier between the mating surfaces of the grinding disc 103 and the mounting plate 102, effectively preventing impurities such as grinding debris, dust, and grinding fluid generated during the grinding operation from seeping into the internal gaps of this structure. At the same time, the elastic restoring force continuously applied by the pressure spring 303 keeps the retaining ring 302 pressed tightly within the annular groove 301, maintaining a stable closed position even when the grinding machine is operating under vibration conditions, ensuring the reliability of the sealing effect.

[0042] This structure effectively seals the splicing gap by adding a retaining ring 302 with a ring groove 301 at the joint of the grinding disc 103 and the mounting disc 102, preventing external impurities from entering the interior of the structure and thus reducing the risk of wear and jamming of parts; moreover, the above structure does not increase the disassembly and assembly steps of the grinding disc 103, and is compatible with the convenience of this structure.

[0043] like Figure 2 , Figure 10 and Figure 11 As shown, each connecting block 104 is rotatably mounted on the grinding disc 103 and can be rotated into the grinding disc 103. After being retracted, the upper surface of the connecting block 104 is flush with the top surface of the grinding disc 103. This structure also includes: a gear ring 401 fixedly mounted on the rotating shaft of each connecting block 104; a return torsion spring 402 fixedly mounted between each connecting block 104 and the grinding disc 103, which keeps the connecting block 104 retracted into the grinding disc 103 in its natural state; and a pusher 403 slidably mounted in the grinding disc 103 along the radial direction of the grinding disc 103, with each connecting block 104 corresponding to a set of pushers 403; each pusher 403 is provided with a toothed array 4031, and each pusher 403 is connected to the corresponding connecting block 104 through the toothed array 4031. The gear ring 401 on the 4 meshes with the pusher 403, thereby converting the linear movement of the pusher 403 into the rotational movement of the connecting block 104; the control disk 404, which is rotatably installed in the grinding disk 103, is coaxially arranged with the grinding disk 103 and can act on each pusher 403; the control disk 404 is provided with an arc segment 4041 and a straight segment 4042 corresponding to each pusher 403; wherein, the arc segment 4041 protrudes outward from the outer periphery of the control disk 404, and the straight segment 4042 is located at the outermost end of the arc segment 4041 and is perpendicular to the radial direction of the control disk 404. The control disk 404 converts its own rotational movement into the radial movement of the pusher 403 through the arc segment 4041, and holds the pusher 403 in the pushed-out position through the straight segment 4042.

[0044] like Figure 10 and Figure 11As shown, an inner angle shaft 405 is fixedly installed at the center of the control disk 404. The top surface of the inner angle shaft 405 is flush with the top surface of the grinding disc 103 and has no outward protrusion. The operator can rotate the control disk 404 by using a special tool in conjunction with the inner angle shaft 405. An indicator mark 406 is provided on the inner angle shaft 405. A marking mark 407 is provided on the grinding disc 103 and corresponds to the outer ring of the inner angle shaft 405. There are two marking marks 407. When the inner angle shaft 405 rotates to the point where the indicator mark 406 corresponds to the two marking marks 407 respectively, it means that the connecting block 104 is in the fully extended state and the retracted state respectively, so that the operator can quickly locate the rotation position of the control disk 404 and improve the convenience of operation.

[0045] When the connecting block 104 needs to be unfolded, the rotating inner angle shaft 405 drives the control disk 404 to rotate. The arc segment 4041 on the control disk 404 contacts and engages with the pusher 403, pressing the pusher 403 to move radially toward the connecting block 104 along the grinding disc 103. The pusher 403 drives the connecting block 104 to rotate synchronously through the meshing of the gear ring 401 and the gear 4031, and the return torsion spring 402 is twisted and deformed accordingly. When the control disk 404 continues to rotate until the straight segment 4042 contacts the pusher 403, the pusher 403 is held in the pushed-out position, and the connecting block 104 is in an unfolded state perpendicular to the top surface of the grinding disc 103.

[0046] When the connecting block 104 needs to be stored, the inner angle shaft 405 is rotated in the opposite direction. The straight section 4042 and the arc section 4041 of the control disk 404 disengage from the pusher 403 in sequence, and the pusher 403 loses its radial support force. At this time, the elastic restoring force of the reset torsion spring 402 drives the connecting block 104 to rotate in the opposite direction, and drives the pusher 403 to reset through the meshing of the gear ring 401 and the toothed rack 4031. The connecting block 104 rotates and is stored in the grinding disc 103, restoring the retracted state flush with the top surface of the grinding disc 103.

[0047] This structure uses a control panel 404 to link all pushers 403 and gear rings 401, enabling the one-step synchronous storage and unfolding of all connecting blocks 104, making operation simple and efficient. During transportation and storage, by storing the connecting blocks 104 inside the grinding disc 103, the space occupied by the grinding disc 103 can be significantly reduced, improving space utilization and stacking regularity. At the same time, the internal storage of the connecting blocks 104 can prevent the structure from being exposed and suffering structural damage such as collisions and bending during transportation, thus eliminating the risk of the grinding disc 103 being scrapped due to damage to the connecting blocks 104.

[0048] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention are existing technologies known to those skilled in the art.
