Description

Technical Field

[0001] This invention relates to the field of plastic sheet processing technology, and in particular to a precision machine tool for grooving and grinding plastic sheets. Background Technology

[0002] Plastic sheets are sheets made of plastic. Plastic is a synthetic polymer compound that can be freely shaped and molded. Plastic is a material made by polymerizing monomer raw materials through synthesis or condensation reactions. Its main component is synthetic resin. It has advantages such as resistance to chemical corrosion, gloss, transparency or translucency, being mostly a good insulator, being lightweight and strong, having a wide range of uses, being easy to color, and being resistant to high temperatures in some cases. It is widely used in social life.

[0003] Currently, in the manufacturing process of plastic sheets, long strips of plastic sheets are first cut into several sheet-like plastic sheets. The cut edges of these plastic sheets will have burrs, and some plastic sheets need to have various shaped slots made on their surface during subsequent use, such as square slots and triangular slots. At present, grinding or grooving these sheet-like plastic sheets requires manual operation or the use of different processing equipment, which increases production costs. If processing both sides of the plastic sheet, manual operation is required to flip it over, which is cumbersome and has low processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a precision machine tool for grooving and grinding plastic sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A support frame is fixedly connected to the inner wall of the U-shaped plate. A second shaft is rotatably connected through the inner wall of the support frame. A rectangular block is fixedly connected to the side wall of the second shaft. A third shaft is rotatably connected through the inner wall of the rectangular block. A clamping plate is fixedly connected to one end of the third shaft. A gear is fixedly connected to the side wall of the third shaft. A limit ball is fixedly connected to the other end of the third shaft. A support plate is fixedly connected to the inner wall of the U-shaped plate. A first shaft is rotatably connected through the inner wall of the support plate. An end face cam and a circular plate are sequentially fixedly connected to the lower side wall of the first shaft. Multiple toothed blocks are fixedly connected circumferentially to the top wall of the circular plate. The gear and the multiple toothed blocks mesh with each other. The limit ball and the inner wall of the end face cam are connected... The second shaft is fixedly connected to a pull ring at one end, and a column is fixedly connected to the inner wall of the base. The column is elastically connected to the pull ring via a spring. A connecting rod is rotatably connected to the inner wall of the support plate. A small gear is fixedly connected to the side wall of the connecting rod. A large gear is fixedly connected to the side wall of the first shaft. The large gear and the small gear mesh. An arc-shaped triangular block is fixedly connected to the side wall of the connecting rod. A U-shaped block is symmetrically fixedly connected to the inner wall of the U-shaped plate. A horizontal plate is slidably connected to the inner wall of each U-shaped block. A rectangular frame is fixedly connected to the two horizontal plates at their close ends. A load-bearing plate is slidably connected inside the rectangular frame. A square frame is fixedly connected to one end of the load-bearing plate. The square frame is fitted onto the side wall of the arc-shaped triangular block. A grooving machine is fixedly connected to the inner wall of the other end of the load-bearing plate.

[0007] Furthermore, an L-shaped plate is fixedly connected to the top wall of the base, and multiple brush bristles are fixedly connected to the inner wall of the L-shaped plate. Multiple suction tubes are fixedly connected through the inner wall of the L-shaped plate.

[0008] Furthermore, the herringbone block is made of magnetic material, and each of the horizontal plates has a cavity on its inner wall. A magnetic block is slidably connected inside the cavity, and an air inlet pipe and an air outlet pipe are fixedly connected through the inner wall of the cavity.

[0009] Furthermore, the end of the air inlet pipe away from the cavity is fixedly connected to multiple suction pipes, and the end of the air outlet pipe away from the cavity is fixedly connected to an environmentally friendly dust removal bag. Both the air inlet pipe and the air outlet pipe are equipped with one-way valves.

[0010] Furthermore, a folding rod is fixedly connected to the top wall of the U-shaped plate, a motor is fixedly connected to one end of the folding rod, a rotating rod is fixedly connected to the output end of the motor, the end of the rotating rod away from the motor passes through the inner wall of the U-shaped plate and is rotatably connected to the inner wall of the base, and a grinding disc is fixedly connected to the side wall of the rotating rod.

[0011] Furthermore, a driving wheel is fixedly connected to the side wall of the rotating rod, and a driven wheel is fixedly connected to the side wall of the first shaft. The driving wheel and the driven wheel are connected by a synchronous belt.

[0012] Furthermore, the inner wall of the clamping plate is provided with clamping components for fixing the plastic plate.

[0013] The present invention has the following advantages:

[0014] 1. By setting up structures such as end face cam, third axis and clamping plate, when the third axis is in an inclined state, the cut part of the plastic board to be processed fixed on the clamping plate and the upper surface of the grinding disc are in contact for grinding. When the third axis is in a horizontal state, the movement trajectory of the drill bit part of the grooving machine fixedly connected to its bottom wall by the load-bearing plate is square, so that a square groove is drilled on the upper surface of the plastic board to be processed.

[0015] 2. By setting up structures such as a spiral block, horizontal plate and bristles, multiple bristles come into contact with the upper surface of the grinding disc to clean the grinding debris remaining on the upper surface of the grinding disc. Meanwhile, the magnetic block and the cavity slide relative to each other, allowing the grinding debris trapped inside the cavity to be drawn in from the suction pipe, thus completing the cleaning of the upper surface of the grinding disc and preventing grinding debris from accumulating on the upper surface of the grinding disc and affecting the subsequent grinding quality.

[0016] 3. When the limit ball is about to disengage from the trapezoidal protrusion of the end face cam, the gear set on the side wall of the third shaft in a horizontal state will mesh with multiple tooth blocks on the circular plate. The gear drives the third shaft, the clamping plate and the plastic plate to be processed to rotate 180 degrees, so as to perform drilling, grooving and grinding on the other surface of the plastic plate to be processed. There is no need for manual flipping of the plastic plate to be processed, saving labor and improving processing efficiency. Attached Figure Description

[0023] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Reference Figure 1-5A precision machine tool for grooving and grinding plastic sheets includes a base 1. A U-shaped plate 35 is fixedly connected to the top wall of the base 1. A support frame 7 is fixedly connected to the inner wall of the U-shaped plate 35. A second shaft 8 is rotatably connected through the inner wall of the support frame 7. A rectangular block 9 is fixedly connected to the side wall of the second shaft 8. A third shaft 10 is rotatably connected through the inner wall of the rectangular block 9. A clamping plate 13 is fixedly connected to one end of the third shaft 10. A gear 11 is fixedly connected to the side wall of the third shaft 10. The other end of the third shaft 10 is fixed... A limiting ball 12 is connected to the inner wall of a U-shaped plate 35, and a support plate 5 is fixedly connected to the inner wall of the support plate 5. A first shaft 4 is rotatably connected through the inner wall of the support plate 5. An end face cam 6 and a circular plate 36 are fixedly connected to the lower side wall of the first shaft 4 in sequence. Multiple toothed blocks 37 are fixedly connected to the top wall of the circular plate 36 circumferentially. The gear 11 and the multiple toothed blocks 37 are meshed and connected. The limiting ball 12 and the inner wall of the end face cam 6 slide against each other. A pull ring 14 is fixedly connected to one end of the second shaft 8, and a column 15 is fixedly connected to the inner wall of the base 1. The column 15 is elastically connected by a spring 16 and a pull ring 14. A connecting rod 39 is rotatably connected to the inner wall of the support plate 5. A small gear 40 is fixedly connected to the side wall of the connecting rod 39. A large gear 41 is fixedly connected to the side wall of the first shaft 4. The large gear 41 and the small gear 40 mesh. An arc-shaped triangular block 18 is fixedly connected to the side wall of the connecting rod 39. A spiral block 21 is symmetrically fixedly connected to the inner wall of the U-shaped plate 35. A horizontal plate 22 is slidably connected to the inner wall of each spiral block 21. The ends of two horizontal plates 22 are close to each other. A rectangular frame 20 is fixedly connected to the load-bearing plate 19, which is slidably connected inside the rectangular frame 20. A square frame 17 is fixedly connected to one end of the load-bearing plate 19, and the square frame 17 is fitted onto the side wall of the arc-shaped triangular block 18. A grooving machine 38 is fixedly connected to the inner wall of the other end of the load-bearing plate 19. The arc-shaped triangular block 18 has a Reuleaux triangle structure, and the middle part of the clamping plate 13 is hollowed out, so that the grooving machine 38 can perform double-sided grooving on the plastic plate to be processed fixed on the clamping plate 13.

[0025] An L-shaped plate 27 is fixedly connected to the top wall of the base 1. Multiple brush bristles 28 are fixedly connected to the inner wall of the L-shaped plate 27. Multiple suction tubes 29 are fixedly connected through the inner wall of the L-shaped plate 27. The multiple brush bristles 28 contact the upper surface of the grinding disc 31, thereby cleaning the grinding debris remaining on the upper surface of the grinding disc 31.

[0026] The herringbone block 21 is made of magnetic material. Each horizontal plate 22 has a cavity 23 on its inner wall. A magnetic block 24 is slidably connected inside the cavity 23. An air inlet pipe 25 and an air outlet pipe 26 are fixedly connected through the inner wall of the cavity 23. The herringbone block 21 and the magnetic block 24 have opposite polarities and are magnetically attracted to each other. Under the magnetic attraction of the herringbone block 21, the horizontal plate 22, which moves back and forth, will drive the cavity 23 and the magnetic block 24 to slide in a sealed manner. Then, the polishing debris that has been swept and trapped is drawn into the cavity 23 from the suction pipe 29.

[0027] The end of the air inlet pipe 25 away from the cavity 23 is fixedly connected to multiple suction pipes 29, and the end of the air outlet pipe 26 away from the cavity 23 is fixedly connected to an external environmental dust collection bag. Both the air inlet pipe 25 and the air outlet pipe 26 are equipped with one-way valves. The one-way valve in the air inlet pipe 25 only allows the gas and debris in the suction pipes 29 to enter the cavity 23, while the one-way valve in the air outlet pipe 26 only allows the gas and debris in the cavity 23 to enter the external environmental dust collection bag for collection.

[0028] A folding rod 2 is fixedly connected to the top wall of the U-shaped plate 35. A motor 3 is fixedly connected to one end of the folding rod 2. A rotating rod 30 is fixedly connected to the output end of the motor 3. The end of the rotating rod 30 away from the motor 3 passes through the inner wall of the U-shaped plate 35 and is rotatably connected to the inner wall of the base 1. A grinding disc 31 is fixedly connected to the side wall of the rotating rod 30. The output end of the motor 3 drives the rotating rod 30 to rotate, and then the rotating rod 30 drives the grinding disc 31 to rotate. The grinding disc 31 can grind the burrs on the cut edge of the plastic plate.

[0029] A drive wheel 32 is fixedly connected to the side wall of the rotating rod 30, and a driven wheel 33 is fixedly connected to the side wall of the first shaft 4. The drive wheel 32 and the driven wheel 33 are connected by a timing belt 34. The rotating rod 30 drives the first shaft 4 to rotate through the drive wheel 32, the timing belt 34 and the driven wheel 33.

[0030] The inner wall of the clamping plate 13 is provided with clamping components for fixing the plastic plate. The function of the clamping components is to fix the plastic plate to be processed, which can be accomplished by existing technology and will not be described in detail here.

[0031] In this invention, the plastic sheet to be processed is fixed on the upper part of the clamping plate 13. One end of the cut portion of the plastic sheet extends from the clamping plate 13 to the outside. The motor 3 is turned on, and the output end of the motor 3 drives the rotating rod 30 to rotate. In turn, the rotating rod 30 drives the grinding disc 31 to rotate. The rotating rod 30 drives the first shaft 4 to rotate through the driving wheel 32, the synchronous belt 34 and the driven wheel 33. The first shaft 4 drives the small gear 40 and the connecting rod 39 to rotate through the large gear 41. The transmission ratio of the large gear 41 and the small gear 40 is set so that the connecting rod 39 can obtain a faster rotation speed.

[0032] The first shaft 4 drives the end face cam 6 and the circular plate 36 to rotate. The end face cam 6 is composed of a circular disc and a trapezoidal protrusion with an arc structure. Since the spring 16 always provides tension to the pull ring 14, the pull ring 14 will drive the second shaft 8 to rotate at a certain angle. The second shaft 8 drives the rectangular block 9 to rotate at a certain angle, and then the rectangular block 9 causes the third shaft 10 to tilt. The clamping plate 13, which is fixedly connected to one end of the third shaft 10, tilts downward and approaches the grinding disc 31, so that the cut part of the plastic board to be processed, which is fixed on the clamping plate 13, comes into contact with the upper surface of the grinding disc 31, and the burrs on the cut part of the plastic board to be processed are ground. The other end of the third shaft 10 tilts upward, so that the limiting ball 12 and the bottom wall of the end face cam 6 slide against each other. When the end face cam 6 and the circular plate 36 rotate, when the limiting ball 12 and the trapezoidal protrusion of the end face cam 6 come into contact, the limiting ball 12 stops sliding. Ball 12 will drive the third shaft 10 to a horizontal state. When the third shaft 10 is in a horizontal state, due to the different transmission ratios of the large gear 41 and the small gear 40, the connecting rod 39 will rotate faster. The connecting rod 39 will drive the arc triangular block 18 to move. The arc triangular block 18 has a Reuleaux triangle structure, which in turn drives the square frame 17 fitted on its side wall to move. The square frame 17 drives the load-bearing plate 19 to move. Since the load-bearing plate 19 is slidably connected inside the rectangular frame 20, the rectangular frame 20 will drive the two horizontal plates 22 to move back and forth horizontally inside the two loop blocks 21. This will cause the load-bearing plate 19 to drive the drill bit of the grooving machine 38, which is fixedly connected to its bottom wall, to move in a square trajectory. Then the drill bit of the grooving machine 38 will abut against the upper surface of the plastic board to be processed, thereby drilling a square groove on the upper surface of the plastic board to be processed.

[0033] Meanwhile, because the magnetic material ring block 21 and magnetic block 24 have opposite polarities and attract each other, the reciprocating horizontal plate 22 will cause the cavity 23 and magnetic block 24 to slide under the magnetic attraction of the ring block 21. Multiple bristles 28 will come into contact with the upper surface of the polishing disc 31, thereby cleaning the polishing debris remaining on the upper surface of the polishing disc 31. Meanwhile, the magnetic block 24 and the cavity 23 will slide relative to each other, allowing the polishing debris trapped inside the cavity 23 to be drawn in from the suction tube 29, thus completing the cleaning of the upper surface of the polishing disc 31 and preventing the polishing debris from accumulating on the upper surface of the polishing disc 31 and affecting the subsequent polishing quality.

[0034] When the limiting ball 12 is about to disengage from the trapezoidal protrusion of the end face cam 6, the gear 11 on the side wall of the horizontal third shaft 10 will mesh with multiple tooth blocks 37 on the circular plate 36. The gear 11 will then drive the third shaft 10 to rotate 180 degrees. The third shaft 10 is damped inside the rectangular block 9 and requires a certain external force to rotate. Only then can the third shaft 10 drive the clamping plate 13 and the plastic sheet to be processed to rotate 180 degrees. Then the above process is repeated to drill, groove and grind the other surface of the plastic sheet to be processed. There is no need for manual flipping of the plastic sheet to be processed, saving labor and improving processing efficiency.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
