Description

Technical Field

[0001] This utility model relates to the field of cutting auxiliary device technology, and in particular to a follow-up clamping device for cutting irregular curves of quartz stone slabs. Background Technology

[0002] Quartz stone slabs are a widely used hard material in architectural decoration, home countertops, and other fields. During the cutting process of quartz stone slabs, especially when processing large slabs, due to their large size and weight, the cutting head is typically controlled to move along a preset trajectory. This avoids positioning errors and safety hazards caused by moving the slab itself, thus ensuring the accuracy of the cutting path and processing efficiency.

[0003] However, in actual processing, when cutting irregular curves, such as arcs or wavy lines, the cutting head is easily affected by the combined effects of friction on the sheet surface, feed force, and internal material stress during its movement. This can cause the cutting trajectory to deviate from the preset path. In short, the cutting head is prone to slippage when processing curved sections, resulting in a deviation between the actual cutting path and the theoretical path. This deviation not only affects the quality of the cut edge, causing roughness or chipping, but also leads to uneven gaps and poor fit during sheet splicing and installation, seriously affecting the product's aesthetics and performance. Utility Model Content

[0004] To address the aforementioned deficiencies in the prior art, this utility model provides a follow-up clamping device for cutting irregular curve quartz stone slabs. This device achieves localized clamping of the quartz stone slabs while following the displacement of the cutting blade, thereby improving the cutting accuracy and processing quality of the quartz stone slabs.

[0005] The technical solution is: a follow-up clamping device for cutting irregular curves of quartz stone slabs, including: a processing base and a moving arm; the device further includes: a cutting component, assembled on the moving arm, for cutting quartz stone slabs, the movement trajectory of the cutting component being set by the processing base and the moving arm; and a clamping component, assembled on the cutting component, for dynamically clamping the quartz stone slabs. The cutting assembly includes: a rotating arm rotatably connected to the end of a movable arm and driven to rotate by the movable arm; a first mounting plate fixedly connected to the rotating arm; and a cutting blade fixedly connected to the first mounting plate for cutting quartz stone slabs. The rotating arm rotates to adjust the cutting angle of the cutting blade. The clamping assembly includes: a mounting base, fixedly connected to the rotating arm; a second mounting plate, symmetrically arranged on both sides of the mounting base; a sleeve rod, fixedly connected to the second mounting plates on both sides; a pressure plate, slidably sleeved on the lower part of the sleeve rod; a return spring, fixedly connected between the pressure plate and the sleeve rod; a base plate, located at the bottom of the pressure plate; and a ball bearing, rotatably connected to the bottom of the base plate, which will roll in contact with the quartz stone slab, with its bottom horizontal cut surface protruding beyond the bottom horizontal cut surface of the cutting blade.

[0006] Further explanation: the clamping assembly also includes: a limiting rod, fixedly connected to both sides of the mounting base, with two sets of second mounting plates slidingly engaged with the limiting rods on both sides respectively; and a bidirectional screw, rotatably connected to the mounting base, having two threaded sections with opposite directions of rotation, with the two sets of second mounting plates threadedly engaged with the two threaded sections with opposite directions of rotation respectively.

[0007] Furthermore, the device also includes: a guide rod, fixedly connected to the base plate, the base plate and the pressure plate forming a sliding fit through the guide rod; and an adjusting screw, rotatably connected to the base plate and forming a threaded fit with the pressure plate.

[0008] To further explain, the device also includes a graduated ring, which is fixedly connected to the guide rod.

[0009] Furthermore, the device also includes a dust cover, which is fixedly connected to the first mounting plate and covers the outside of the cutting blade to intercept dust generated during the cutting operation.

[0010] Furthermore, the device also includes friction textures, which are distributed on the ends of the adjusting screw and the bidirectional screw to increase the coefficient of friction with the hand.

[0011] The beneficial effects of this utility model are as follows: 1. By setting the clamping component to move synchronously with the cutting component, the ball bearings are used to achieve rolling contact with the quartz stone slab, thereby ensuring that the return spring continuously applies force, thus achieving dynamic clamping of the quartz stone slab, preventing the cutting blade from slipping off the quartz stone slab or shifting relative to the quartz stone slab, and ensuring the accuracy of the cutting trajectory.

[0012] 2. The adjustable spacing between the pressure plate and the cutting blade allows for the adaptation of quartz stone slabs with different cutting widths, ensuring a firming effect on the quartz stone slabs; and the use of a two-way screw enables synchronous adjustment of the pressure plates on both sides, ensuring uniform force on both sides of the quartz stone slabs and convenient operation.

[0013] 3. By setting the height of the actual pressing surface of the pressure plate to be adjustable, it can be adapted to quartz stone slabs of different thicknesses, ensuring that the return spring always provides sufficient pressing force and maintains a stable pressing effect.

Detailed Implementation

[0019] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0020] Example: A follow-up clamping device for cutting irregular curves in quartz stone slabs, combined with... Figures 1-4 As shown, the device includes: a processing base 1; a movable arm 2, slidably mounted on the processing base 1, which is driven by the processing base 1 to perform horizontal lateral displacement; the device also includes: a cutting component 3, assembled on the movable arm 2, used to cut quartz stone slabs, which is driven by the movable arm 2 to perform horizontal longitudinal displacement and vertical displacement, wherein the horizontal longitudinal displacement is used to cooperate with the aforementioned horizontal lateral displacement to jointly set the movement trajectory of the cutting component 3, and the vertical displacement is used to drive the cutting component 3 to move closer to or away from the quartz stone slab; and a pressing component 4, assembled on the cutting component 3, which moves synchronously with the cutting component 3 to achieve dynamic pressing of the quartz stone slab; The cutting assembly 3 includes: a rotating arm 301, which is rotatably mounted on the end of the movable arm 2 and driven to rotate by the movable arm 2; a first mounting plate 302, which is fixedly mounted on the rotating arm 301; and a cutting blade 303, which is fixedly mounted on the first mounting plate 302 and is used to cut quartz stone slabs. The rotating arm 301 rotates to adjust the cutting angle of the cutting blade 303. The clamping assembly 4 includes: a mounting base 401, fixedly mounted on the rotating arm 301; second mounting plates 403, symmetrically arranged on both sides of the mounting base 401; a sleeve rod 404, vertically fixedly mounted on the bottom of the second mounting plates 403 on both sides; a pressure plate 406, slidably sleeved on the lower part of the sleeve rod 404, and vertically displaced along the sleeve rod 404; a return spring 405, fixedly mounted between the pressure plate 406 and the sleeve rod 404, generating a clamping force through compression deformation; a base plate 6, located at the bottom of the pressure plate 406; and a ball bearing 9, rotatably mounted on the bottom of the base plate 6, which will roll into contact with the quartz stone slab. Its bottom horizontal cut surface must protrude beyond the bottom horizontal cut surface of the cutting blade 303 to ensure that the ball bearing 9 contacts the quartz stone slab before the cutting blade 303.

[0021] First, based on the target curve of the quartz stone slab to be cut, the horizontal movement trajectory of the cutting component 3 is preset. After the preset parameters are confirmed, the moving arm 2 drives the cutting component 3 and the pressing component 4 to move downward synchronously until the cutting blade 303 and the ball bearing 9 both contact the surface of the quartz stone slab. At this time, since the pressure plate 406 contacts the quartz stone slab first, it is squeezed and moves upward, which displaces the relative sleeve rod 404 and compresses the return spring 405. The return tendency of the return spring 405 is transmitted to the quartz stone slab through the pressure plate 406 and the bottom plate 6, forming a stable pressing force.

[0022] After the device is started, the processing base 1 drives the moving arm 2 and its cutting component 3 to complete the horizontal lateral displacement, and the moving arm 2 drives the cutting component 3 to complete the horizontal longitudinal displacement. The two work together to achieve trajectory positioning. At the same time, the moving arm 2 drives the rotating arm 301 to rotate synchronously, adjusting the angle of the cutting blade 303 to be tangent to the cutting curve in real time to ensure the smoothness of the cutting line. During the entire cutting process, the ball bearing 9 rolls on the surface of the quartz stone slab with the displacement of the cutting component 3, so that the return spring 405 is always kept in a compressed state, continuously applying a pressing force to the quartz stone slab, which can effectively prevent the cutting blade 303 from slipping off the quartz stone slab and ensure the cutting accuracy and effect of the device.

[0023] After a single cut is completed, the moving arm 2 controls the cutting component 3 and the clamping component 4 to move upward and detach from the surface of the quartz stone slab. If further cutting is required, the cutting component 3 is moved to the next cutting position and the cutting operation is repeated. If all cutting operations are completed, the cutting component 3 is controlled to return to the initial position and wait for the next operation.

[0024] Combination Figures 1-3As shown, the clamping assembly 4 also includes: a limiting rod 402, which is fixedly installed on both sides of the mounting base 401, and two sets of second mounting plates 403 are respectively slidably engaged with the limiting rods 402 on both sides; a bidirectional screw 407, which is rotatably installed on the front side of the mounting base 401, and has two threaded sections with opposite directions of rotation, and the two sets of second mounting plates 403 are respectively threadedly engaged with these two threaded sections with opposite directions of rotation.

[0025] By rotating the bidirectional screw 407, the second mounting plates 403 on both sides can be driven to move in opposite directions or away from each other along the limiting rod 402. That is, before the cutting operation, the distance between the pressure plates 406 on both sides and the cutting blade 303 is adjusted according to the width of the quartz stone slab to be cut, so that the position of the pressure plates 406 is adapted to the quartz stone slab to ensure the pressing effect. By adjusting the pressure plates 406 on both sides simultaneously through the bidirectional screw 407, the ease of operation can be improved, and the pressing balance of the quartz stone slab on both sides can be ensured, so that the quartz stone slab is subjected to uniform force.

[0026] Combination Figure 1 , Figure 2 and Figure 4 As shown, the device also includes: a guide rod 7, which is fixedly installed on the base plate 6, and the base plate 6 forms a sliding fit with the pressure plate 406 through the guide rod 7; and an adjusting screw 5, which is rotatably installed on the base plate 6 and forms a threaded fit with the pressure plate 406.

[0027] By rotating the adjusting screw 5, the base plate 6 can be driven to move up and down along the guide rod 7, thereby adjusting the height of the base plate 6 and changing the height of the actual pressing surface of the pressing component 4, so that the pressing component 4 can be adapted to quartz stone slabs of different thicknesses, ensuring that sufficient pressing force can be applied to quartz stone slabs of various thicknesses and always maintaining a stable pressing effect.

[0028] Combination Figures 1-4 As shown, it also includes: a scale ring 8, fixedly installed on the guide rod 7. When adjusting the height of the two base plates 6, the scale value on the scale ring 8 can be observed to conveniently achieve synchronous alignment of the adjustment positions of the two base plates 6, thereby avoiding the imbalance of force on the clamping component 4 due to the inconsistent height of the two base plates 6, ensuring that the bottom of the ball 9 always remains horizontal and applies uniform clamping force to the quartz stone slab; a dust cover 10, fixedly installed on the first mounting plate 302, covering the outside of the cutting blade 303, used to intercept the dust generated during the cutting operation. On the one hand, it can prevent the dust generated during the cutting process from splashing into the device and causing jamming or wear to the moving parts in the device, thus ensuring the stability of the device's operation. On the other hand, it can reduce the diffusion of dust into the working environment and improve the cleanliness of the operating environment; friction texture 11, arranged on the rod ends of the adjusting screw 5 and the bidirectional screw 407, used to increase the coefficient of friction with the hand. The friction texture 11 improves the stability of the hand grip during operation, making parameter adjustment more accurate and effortless.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
