Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a fixing device for stone processing. Background Technique

[0002] A fixing device is a device that can effectively fix a workpiece to avoid lateral and sideward movement, and is widely used in various industrial fields. When processing stone materials such as cutting and drilling, in order to keep the stone fixed during the processing to improve the processing accuracy, a fixing device is needed to fix the stone so that it can always remain locked and will not slide during the processing. The fixing device generates a downward pressure through a pressing member and applies the pressure to the stone through a contacting member to lock the stone. The operation is simple, the fixing effect is good, and the applicability is strong.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: when the existing fixing device fixes a waxed and smooth stone slab, since the surface of the stone slab has been waxed and is relatively smooth, a relatively large pressure is required to effectively fix it during fixing. After applying a relatively large pressure, it is easy to cause the surface of the stone slab to be subjected to a relatively large pressure and produce indentations, thereby affecting the smoothness and easily generating defective products. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for stone processing that is not easy to produce indentations and has a low defect rate in view of the defects and deficiencies of the prior art.

[0005] To achieve the above object, the present utility model adopts the following technical solutions: A fixing device for stone processing, comprising a processing table and a feeder disposed on the processing table. An elevating frame is further provided on the processing table. A pressure rod is slidably disposed on the elevating frame. The pressure rod includes a sliding rod slidably disposed on the elevating frame and a connecting plate disposed on the bottom surface of the sliding rod. An extrusion disc is disposed on the bottom surface of the connecting plate. A compression frame is disposed between the top surface of the extrusion disc and the bottom surface of the connecting plate. A suction pressure pipe penetrates through the extrusion disc. The top end of the suction pressure pipe penetrates through the connecting plate and the sliding rod and the end is connected to the outside. When the sliding rod moves downward to apply pressure and the extrusion disc contacts the stone, and when the pressure is too large, the excessive extrusion pressure is absorbed through the compression frame. At the same time, the suction pressure pipe is squeezed to generate suction to fix the stone. The suction pressure pipe includes a compression pipe penetrating through the extrusion disc and a discharge pipe disposed on the top surface of the compression pipe and communicated with the compression pipe. The top end of the discharge pipe penetrates through the connecting plate and the sliding rod and the end is connected to the outside. A blocking block is disposed on the inner wall of the discharge pipe. A blocking frame is disposed in a fitting manner on the upper surface of the blocking block. A sliding groove is disposed on the inner wall of the discharge pipe above the blocking frame. An upper top column with the top end slidably connected to the inner wall of the sliding groove is disposed on the upper surface of the blocking frame. A return spring is disposed between the top end of the upper top column and the inner wall of the sliding groove.

[0006] Further improvement is: An elevating base is further provided on the bottom surface of the processing table.

[0007] Further improvement is: A downward pressing air cylinder connected to the upper surface of the sliding rod is further provided at the top of the elevating frame.

[0008] Further improvement is: A positioning column is further provided on the surface of the sliding rod.

[0009] Further improvement is: An arc-shaped elastic return piece is disposed on the inner wall of the compression pipe.

[0010] Further improvement is: A guiding block is disposed on the bottom surface of the blocking block.

[0011] Further improvement is: An adsorption disc is disposed at the bottom end of the compression pipe.

[0012] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: When the present utility model is used, the stone is fixed by the downward pressing pressure rod. At the same time, when the surface of the stone is extruded, if the pressure is too large, the excessive pressure is absorbed by the mutual movement of the connecting plate and the extrusion disc, and the pressure is converted into the deformation elastic force of the compression frame. At the same time, after the extrusion disc is extruded, the pressure suction pipe is simultaneously extruded to generate an adsorption force to fix the stone. Thus, while ensuring the fixing effect, the surface of the stone is prevented from being indented, and the defect rate is reduced. Description of the Drawings

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] Refer to Figures 1-3As shown in the figure, the technical solution adopted in this specific embodiment is as follows: A fixing device for stone processing includes a processing table 2 and a feeder 3 arranged on the processing table 2. An elevating frame 4 is also provided on the processing table 2. A pressure rod 5 is slidably arranged on the elevating frame 4. The pressure rod 5 includes a sliding rod 51 slidably arranged on the elevating frame 4 and a connecting plate 52 arranged on the bottom surface of the sliding rod 51. An extrusion disc 53 is arranged on the bottom surface of the connecting plate 52. A compression frame 54 is arranged between the top surface of the extrusion disc 53 and the bottom surface of the connecting plate 52. A suction pressure pipe 55 penetrates through the extrusion disc 53. The suction pressure pipe 55 includes a compression pipe 32 penetrating through the extrusion disc 53 and a discharge pipe 34 arranged on the top surface of the compression pipe 32 and communicating with the compression pipe 32. The top end of the discharge pipe 34 penetrates through the connecting plate 52 and the sliding rod 51 and its end is communicated with the outside. A blocking block 35 is arranged on the inner wall of the discharge pipe 34. A blocking frame 36 is arranged in a fitting manner on the upper surface of the blocking block 35. The top end of the suction pressure pipe 55 penetrates through the connecting plate 52 and the sliding rod 51 and its end is communicated with the outside. When the sliding rod 51 moves downward to apply pressure and the extrusion disc 53 contacts the stone, and when the pressure is too large, the excessive extrusion force is absorbed by the compression frame 54. At the same time, the suction pressure pipe 55 generates suction after being squeezed to fix the stone. During use, place the stone on the feeder 3 and let it feed the stone under the pressure rod 5. At this time, the elevating frame 4 can be used to guide the downward movement of the pressure rod 5, and the extrusion disc 53 at the bottom of the pressure rod 5 contacts the surface of the stone and squeezes the surface of the stone. When the extrusion force is too large, the excessive pressure will be output to the extrusion disc 53 and cause it to move upward to compress the compression pipe 32 and the compression frame 54, thereby absorbing the excessive pressure. At the same time, after the compression pipe 32 is squeezed, the cavity inside it shrinks, and then the gas inside it moves upward and enters the discharge pipe 34, pushing up the blocking frame 36 that fits with the blocking block 35, so that the gas is discharged outward from the gap between the blocking block 35 and the blocking frame 36, and after being discharged, the blocking frame 36 falls by gravity and fits and closes on the blocking block 35 again to close the discharge pipe 34. Then slightly lift the sliding rod 51, so that the cavity volume of the compression pipe 32 is restored. At this time, the air pressure inside the compression pipe 32 is lower than the external air pressure, and then a suction force is generated at its contact surface with the stone to adsorb the stone, and at the same time, the pressure of the extrusion disc 53 is used to firmly fix the stone, thereby ensuring the fixing effect while avoiding leaving indentations on the surface of the stone and reducing the defect rate;

[0019] An elevating base 1 is also provided on the bottom surface of the processing table 2, which is beneficial to more conveniently control the height of the processing table 2 and make its applicability stronger;

[0020] A downward pressure cylinder 6 connected to the upper surface of the sliding rod 51 is also provided at the top of the elevating frame 4, which is beneficial to automatically pull the sliding rod 51 to move up and down through the downward pressure cylinder 6, thereby making the automation degree higher and being able to output a larger and more controllable downward pressure;

[0021] The surface of the sliding rod 51 is also provided with positioning columns 56, which is beneficial to avoid the deviation of the sliding rod 51 during sliding, fix its trajectory, and increase the fitting degree with the stone;

[0022] The inner wall of the compression tube 32 is provided with an arc-shaped elastic reset piece 33, which is beneficial to make the compression tube 32 recover faster and can withstand and absorb greater excess pressure;

[0023] The inner wall of the discharge pipe 34 is provided with a sliding groove 38 above the blocking frame 36. The upper surface of the blocking frame 36 is provided with an upper top column 37 whose top end is slidably connected to the inner wall of the sliding groove 38. A reset spring 39 is arranged between the top end of the upper top column 37 and the inner wall of the sliding groove 38. When the gas pushes up the blocking frame 36, the reset spring 39 is squeezed to generate elastic force, so that the blocking frame 36 can be reset to fit the surface of the blocking block 35 more quickly, prevent the gas from leaking in, make the adsorption force stronger, and enhance the fixing effect;

[0024] The bottom surface of the blocking block 35 is provided with a guiding block 40, which is beneficial to guide and concentrate the gas, so that it generates a concentrated impact and better pushes the blocking frame 36;

[0025] The bottom end of the compression tube 32 is provided with an adsorption disc 31, which can be made of elastic materials such as rubber and silica gel, which is beneficial to expand the adsorption area, absorb excessive pressure through its elasticity, and increase the friction with the stone, so as to obtain a better fixing effect.

[0026] The working principle of the present utility model: When the present utility model is in use, the stone is placed on the feeder 3 and is fed by the feeder 3 under the pressure rod 5. At this time, the lifting frame 4 can be used to guide the pressure rod 5 to move downward, and the extrusion disc 53 at the bottom of the pressure rod 5 contacts the surface of the stone and extrudes the surface of the stone. When the extrusion force is too large, the excessive pressure will be output to the extrusion disc 53 and cause it to move upward to compress the compression tube 32 and the compression frame 54, thereby absorbing the excessive pressure. At the same time, after the compression tube 32 is squeezed, the internal cavity thereof shrinks, so that the gas inside it moves upward and enters the discharge pipe 34, pushing up the blocking frame 36 that fits the blocking block 35, so that the gas is discharged outward from the gap between the blocking block 35 and the blocking frame 36, and after the discharge, the blocking frame 36 falls by gravity and fits and closes on the blocking block 35 again to close the discharge pipe 34. Then, the sliding rod 51 is slightly lifted, so that the cavity volume of the compression tube 32 is restored. At this time, the air pressure inside the compression tube 32 is lower than the external air pressure, so that a suction force is generated at the contact surface between it and the stone to adsorb the stone, and at the same time, the pressure of the extrusion disc 53 is used to firmly fix the stone, so as to avoid generating indentations on the surface of the stone while ensuring the fixing effect and reducing the defect rate.
