Description

Technical Field

[0001] The invention relates to the technical field of quartz product processing, and more particularly to a quartz round cake chamfering device. Background Art

[0002] At present, the processing of quartz discs requires chamfering operations. The traditional chamfering method is generally to load the quartz disc into a chamfering groove, with the side walls of the chamfering groove tilted, and the tilt angle matches the chamfering angle. Then the chamfering groove rotates, and the worker presses on the quartz disc with his hand to position the quartz disc. The chamfering groove rubs the edge of the quartz disc to complete the chamfering process. This processing method is labor-intensive, and the uneven force causes the chamfer size to be unstable. Employees are required to repeatedly take out the product to check the chamfer size during the operation. The operation is cumbersome, and the processing process is subject to the experience of the workers. The quality of the chamfer cannot be guaranteed. Chinese patent application No. 2021216147196 discloses a quartz ring outer circle chamfering device, which uses a suction cup mechanism carried by a robotic arm to adsorb and position the quartz ring, and then transfers the quartz ring to the chamfering tool so that the edge of the quartz ring contacts the grinding surface for chamfering. This chamfering method can only adapt to chamfering processing at one tilt angle and has poor versatility. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides a quartz disc chamfering device, which facilitates the chamfering operation of the quartz disc, helps to reduce work intensity, improve work efficiency, ensure the uniformity of chamfering, and can realize the processing of chamfering at different inclination angles, with good versatility.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a quartz disc chamfering device, comprising a chamfering sand disc installed on a workbench, a mounting seat that can move horizontally and vertically is installed on the workbench, a chamfering seat that can deflect is installed on the mounting seat, a pressure rod and a rotating shaft are installed on the chamfering seat, a support plate is arranged between the pressure rod and the rotating shaft, the quartz disc is loaded on the support plate, the pressure rod presses the quartz disc, the rotation of the rotating shaft drives the support plate to rotate, and the quartz disc is chamfered against the chamfering sand disc.

[0005] To chamfer a quartz disc, first load the disc between the support plate and the pressure rod. Adjust the deflection angle of the chamfering seat according to the desired chamfer angle. The chamfering disc then rotates, and the rotating shaft drives the disc. The mounting seat moves horizontally and vertically, bringing the disc closer to the chamfering disc. The chamfered edge of the disc is in contact with the disc surface, creating a grinding process.

[0006] During the chamfering process of a quartz disc, clamping and positioning are achieved through the combined action of a support plate and a pressure rod. Chamfering is achieved through the rotation of the rotating shaft and the chamfering sand disc, eliminating the need for manual handling of the quartz disc. This facilitates chamfering operations, reduces workload, improves efficiency, and ensures uniform chamfering. The chamfering seat can be deflected to adjust the angle of the rotating shaft, and thus the clamping angle of the quartz disc, enabling chamfering at various angles, providing excellent versatility.

[0007] Preferably, a pressure ball is installed at the end of the pressure rod, and the pressure ball presses on the quartz disc.

[0008] The pressure rod presses on the quartz disc through the pressure ball on it, thereby realizing the compaction and positioning of the quartz disc. The positioning is reliable, and the contact area between the pressure ball and the quartz disc is small, which reduces the obstruction to the rotation of the quartz disc.

[0009] Preferably, the pressure rod is connected to a tension spring, and the tension spring provides a compression force to the pressure rod.

[0010] The tension spring provides a pressing force to the pressure rod, so that the pressure rod can reliably press and position the quartz disc.

[0011] Preferably, a transverse slide is installed on the workbench, a transverse slide arranged for transverse movement is installed on the transverse slide, a vertical plate is arranged on the transverse slide, and the mounting seat is vertically slidably mounted on the vertical plate.

[0012] The transverse slide moves laterally along the transverse slide seat, and the mounting seat moves vertically along the vertical plate, and the movement is smooth and reliable.

[0013] Preferably, a chamfering motor is installed on the workbench, and the output shaft of the chamfering motor is connected to the chamfering sand disc, and the chamfering sand disc is arranged at an angle.

[0014] The chamfering motor drives the chamfering sand disc to rotate, thereby grinding the edge of the quartz disc to complete the chamfering process.

[0015] Preferably, a fixed pin and a sliding pin are provided on the mounting seat, the chamfered seat is rotatably connected to the fixed pin, an arc-shaped slide groove is provided on the chamfered seat, the sliding pin is movably plug-in connected to the arc-shaped slide groove, and a locking sleeve is connected to the sliding pin to realize the locking positioning of the chamfered seat.

[0016] When the chamfer seat is deflected to adjust the angle, the chamfer seat rotates around the fixed pin. During the rotation, the arc-shaped slide groove and the sliding pin slide against each other. After the chamfer seat is adjusted to the right position, the locking sleeve is tightened to achieve the locking positioning of the chamfer seat.

[0017] Preferably, a mounting cylinder is provided on the chamfered seat, and the rotating shaft is rotatably connected to the mounting cylinder.

[0018] The rotating shaft is rotatably installed in the installation cylinder, which is stable and reliable.

[0019] Preferably, a plurality of positioning rods capable of radially moving and adjusting positions are installed at intervals on the circumference of the chamfered seat, and positioning balls are provided at the ends of the positioning rods, which are pressed against the outer wall of the upper half of the quartz disc.

[0020] Before loading the quartz disc, the positioning rod is moved radially to adjust the position of the positioning ball. Once the adjustment is in place, the quartz disc can be loaded. During loading, the outer wall of the quartz disc is aligned with the positioning ball to ensure the accuracy of the quartz disc loading position and the coaxiality of the quartz disc and the rotating shaft.

[0021] Preferably, a sinking groove is provided on the end surface of the supporting plate, and one end of the quartz disc is adapted to be inserted into the sinking groove.

[0022] The sinking groove plays a good role in positioning the quartz disc, ensuring the coaxiality of the quartz disc and the rotating shaft.

[0023] Another solution is to install a rotating frame on the chamfer seat, and install several rotatable support plates at intervals in the circumferential direction on the rotating frame. The pressure rods and the support plates are arranged on the rotating frame in a one-to-one correspondence; a sliding sleeve is slidably mounted on the rotating shaft, and a push-pull rod is installed on the chamfer seat for movement. The push-pull rod pushes the sleeve to move axially so that the end face of the sleeve contacts or separates from the support plate.

[0024] A plurality of support disks are arranged on the rotating frame. The rotating frame rotates so that the bottom support disk corresponds to the rotating shaft. Then the push-pull rod pushes the sleeve to move axially so that the end face of the sleeve contacts the support disk. At this time, the rotating shaft can drive the support disk in contact with the sleeve to rotate, thereby realizing the rotation of the quartz disc and performing chamfering. During this process, the support disks at other positions are in a stopped state, and the quartz discs can be loaded and unloaded, realizing non-stop chamfering operation, which is conducive to improving work efficiency. When the quartz disc on the bottom support disk completes the chamfering operation, the push-pull rod pushes the sleeve to move axially so that the end face of the sleeve is separated from the support disk. Then the rotating frame rotates so that the next support disk is aligned with the rotating shaft. Then the push-pull rod pushes the sleeve to move axially so that the end face of the sleeve contacts the support disk. The rotating shaft drives the support disk and the quartz disc to rotate and perform chamfering.

[0025] Compared with the prior art, the beneficial effects of the present invention are: (1) the quartz disc chamfering device facilitates the chamfering operation of the quartz disc, which is conducive to reducing work intensity, improving work efficiency, ensuring the uniformity of chamfering, and can realize the processing of chamfering at different inclination angles, with good versatility; (2) during loading, the outer wall of the quartz disc is positioned against the positioning ball, ensuring the accuracy of the loading position of the quartz disc and the coaxiality of the quartz disc and the rotating shaft; (3) through the setting of the rotating frame, the non-stop chamfering operation of the quartz disc can be realized, which is conducive to improving work efficiency.

[0055] During the chamfering process of the quartz disc 24, the support plate 23 and the pressure rod 21 work together to achieve clamping and positioning, and the chamfering process is achieved through the rotation of the rotating shaft 22 and the chamfering sand plate 2, eliminating the need for manual handling of the quartz disc 24. This facilitates the chamfering operation of the quartz disc 24, helping to reduce workload, improve work efficiency, and ensure uniform chamfering. The chamfering seat 16 can deflect to adjust the angle of the rotating shaft 22, and thus the clamping angle of the quartz disc 24, thereby enabling chamfering at different angles, providing excellent versatility.

[0059] A pressure rod 21 and a rotating shaft 22 are mounted on the chamfering seat 16. A support plate 23 is disposed between the pressure rod 21 and the rotating shaft 22. A quartz disc 24 is loaded onto the support plate 23. The pressure rod 21 compresses the quartz disc 24. The rotation of the rotating shaft 22 drives the support plate 23 to rotate, and the quartz disc 24 is chamfered against the chamfering sand disc 2.

[0060] A pressure ball 27 is mounted on the end of the pressure rod 21, pressing against the quartz disc 24. A tension spring 28 is connected to the pressure rod 21, providing a compressive force. The pressure ball 27 on the pressure rod 21 presses against the quartz disc 24, thereby firmly and reliably securing the disc 24. Furthermore, the contact area between the pressure ball 27 and the disc 24 is minimal, minimizing any obstruction to the disc's rotation. The tension spring 28 provides a compressive force to the pressure rod 21, ensuring reliable press-fit and positioning of the disc 24.

[0061] A recessed groove 37 is provided on the end surface of the support plate 23, into which one end of the quartz disc 24 fits. This recessed groove 37 effectively positions the quartz disc 24. A rotating frame 38 is mounted on the chamfering seat 16. Several rotatable support plates 23 are circumferentially spaced apart on the rotating frame 38, with four support plates 23 evenly spaced around the circumference. A posture adjustment shaft 39 is mounted on the rotating frame 38, and a posture adjustment motor 40 is mounted on the chamfering seat 16. The output shaft of the posture adjustment motor 40 is connected to the posture adjustment shaft 39 on the rotating frame 38. The pressure rod 21 and the support plate 23 are arranged on the rotating frame 38 in a one-to-one correspondence; four mounting rings 41 are arranged on the rotating frame 38, the support plate 23 is rotatably connected to the mounting ring 41, a convex ring 42 is arranged on the outer wall of the support plate 23, the mounting ring 41 is tightly connected to the positioning ring 43, a limiting ring groove 44 is formed between the positioning ring 43 and the mounting ring 41, the convex ring 42 is limited in the limiting ring groove 44, a rib rod 45 is connected between the mounting ring 41 and the posture adjustment shaft 39, one end of the pressure rod 21 is rotatably connected to the posture adjustment shaft 39, the other end of the pressure rod 21 is connected to the pressure ball 27, the pressure ball 27 is pressed on the quartz cake 24, one end of the tensioning spring 28 is connected to the pressure rod 21, and the other end of the tensioning spring 28 is connected to the rib rod 45.

[0062] A sliding sleeve 46 is slidably mounted on the rotating shaft 22. A push-pull rod 47 is movably mounted on the chamfered seat 16. A push-pull piston cylinder 48 is mounted on the chamfered seat 16. The push-pull rod 47 is connected to the push-pull piston cylinder 48. The push-pull rod 47 pushes the sliding sleeve 46 axially, causing the end surface of the sliding sleeve 46 to contact or separate from the support plate 23. A stop ring 50 is rotatably mounted on the sliding sleeve 46. A retaining ring 51 is securely attached to the sliding sleeve 46, axially positioning the stop ring 50. The push-pull rod 47 is securely connected to the stop ring 50. A shoulder 49 is provided on the sliding sleeve 46, and the stop ring 50 is axially limited between the shoulder 49 and the retaining ring 51. An anti-rotation groove 52 is provided on the outer wall of the rotating shaft 22, and an anti-rotation rib 53 is provided on the inner wall of the sliding sleeve 46. Both the anti-rotation rib 53 and the anti-rotation groove 52 are axially arranged and adaptively connected, thereby enabling the sliding sleeve 46 to move axially and rotate with the rotating shaft 22. A plurality of radially arranged active ribs 54 are provided on the end surface of the sliding sleeve 46, and a plurality of radially arranged passive ribs 55 are provided on the end surface of the support plate 23. After the end surface of the sliding sleeve 46 contacts the support plate 23, the sliding sleeve 46 rotates with the rotating shaft 22, and the sidewalls of the active ribs 54 abut against the sidewalls of the passive ribs 55, thereby driving the support plate 23 to rotate.

[0063] Multiple support plates 23 are mounted on the rotating frame 38. The rotating frame 38 rotates to align the lowest support plate 23 with the rotating shaft 22. Then, the push-pull rod 47 pushes the sliding sleeve 46 axially, bringing the end surface of the sliding sleeve 46 into contact with the support plate 23. The rotating shaft 22 then drives the support plate 23 in contact with the sliding sleeve 46 to rotate, thereby rotating the quartz disc 24 and performing the chamfering process. During this process, the support plates 23 in other positions are stopped, allowing the quartz disc 24 to be loaded and unloaded, achieving non-stop chamfering operations and improving work efficiency. When the quartz disc 24 on the lowest support plate 23 completes the chamfering operation, the push-pull rod 47 pushes the sleeve 46 to move axially so that the end face of the sleeve 46 is separated from the support plate 23, and then the rotating frame 38 rotates to align the next support plate 23 with the rotating shaft 22, and then the push-pull rod 47 pushes the sleeve 46 to move axially so that the end face of the sleeve 46 contacts the support plate 23, and the rotating shaft 22 drives the support plate 23 and the quartz disc 24 to rotate for chamfering processing.

[0064] When chamfering the quartz disc 24, the deflection angle of the chamfering seat 16 is adjusted according to the desired chamfer angle. The chamfering motor 4 then rotates the chamfering sand disc 2, which in turn rotates the drive motor 26, which in turn rotates the shaft 22, thereby driving the quartz disc 24. The mounting seat 7 moves horizontally and vertically, bringing the quartz disc 24 closer to the chamfering sand disc 2. The chamfer of the quartz disc 24 is in contact with the surface of the chamfering sand disc 2, achieving the chamfering process through grinding.

[0065] During the chamfering process of the quartz disc 24, the support plate 23 and the pressure rod 21 work together to achieve clamping and positioning, and the chamfering process is achieved through the rotation of the rotating shaft 22 and the chamfering sand plate 2, eliminating the need for manual handling of the quartz disc 24. This facilitates the chamfering operation of the quartz disc 24, helping to reduce workload, improve work efficiency, and ensure uniform chamfering. The chamfering seat 16 can deflect to adjust the angle of the rotating shaft 22, and thus the clamping angle of the quartz disc 24, thereby enabling chamfering at different angles, providing excellent versatility.
