[0014] The present invention provides a mechanical processing auxiliary platform, which has the following beneficial effects: (1) The present invention cooperates with a magnet through a motor, a triangular ring, a threaded rod, an L-shaped support plate, a long rod, a protrusion, a T-shaped clamping plate, an arc box and a short column. The motor shaft drives the threaded rod to rotate forward, and the threaded rod drives the protrusion to rotate forward. The protrusion is restricted by the long rod. Under the action of the positive meshing of the thread teeth, one protrusion slides to the right on the threaded rod and drives the T-shaped clamping plate to move to the right. Under the action of the reverse meshing of the thread teeth, the other protrusion slides to the left on the threaded rod and drives the T-shaped clamping plate to slide to the left, so that the T-shaped clamping plate can clamp a smaller or thinner mechanical workpiece, thereby preventing the inconvenience of clamping the mechanical processing auxiliary platform from causing difficulty in processing a smaller or thinner mechanical workpiece. In addition, the T-shaped clamping plate drives the arc box to move toward the middle, the arc box drives the short column to move toward the middle, and the short column drives the magnet to move toward the middle. The magnet is firmly adsorbed on the mechanical workpiece, so that the magnet restricts the mechanical workpiece, thereby preventing the mechanical workpiece on the mechanical processing auxiliary platform from offsetting during processing and causing processing failure.

[0015] (2) The present invention sets an anti-special-shaped device so that the square shell, the cylinder, the column, the porous frame plate, the concave arc strip and the elastic coarse cloth cooperate with the rubber head. Under the clamping force of the T-shaped clamp plate, the cylinder slides in the cylinder. Under the elastic force of the spring in the cylinder, the cylinder is tightly pressed against the mechanical workpiece, so that the irregular-shaped mechanical workpiece can be clamped by the machining auxiliary platform, preventing the machining auxiliary platform from clamping the mechanical workpiece with an arc surface or an irregular shape, which makes it difficult to process the special-shaped mechanical workpiece. In addition, the cylinder drives the rubber head to move toward the middle, and the rubber head presses against the elastic coarse cloth to move toward the middle. The elastic coarse cloth is connected to the mechanical workpiece. When the surface of the workpiece is touched, the elastic coarse cloth wraps the surface of the mechanical workpiece, and the rubber head rests on the elastic coarse cloth. The rough surface of the elastic coarse cloth wraps the mechanical workpiece, and under the action of friction, the mechanical workpiece is restricted from sliding, and the surface of the mechanical workpiece is prevented from being too smooth and causing slipping during the clamping process. The elastic coarse cloth absorbs the protective solvent on the mechanical workpiece when wrapping the surface of the mechanical workpiece, and the protective solvent on the mechanical workpiece is prevented from accumulating on the equipment. When the elastic coarse cloth restricts the mechanical workpiece, the elastic coarse cloth will not scratch the surface of the mechanical workpiece, and the machining auxiliary platform is prevented from scratching the surface of the mechanical workpiece when clamping the mechanical workpiece.

[0016] (3) The present invention arranges an anti-shake device so that the arc-shaped support plate, strip plate, support column, arc-shaped spring sheet, U-shaped frame, rubber roller, arc plate and rubber strip cooperate with the arc-shaped rubber pad. The rubber roller slides toward the middle on the strip plate, and the rubber roller drives the U-shaped frame to move to the bottom of the mechanical workpiece. The U-shaped frame is tightly pressed against the bottom of the mechanical workpiece under the elastic force of the arc-shaped spring sheet, so as to prevent the mechanical workpiece on the machining platform from shaking at the bottom during machining, thereby causing poor workpiece finishing effect. In addition, the arc-shaped rubber pad contacts the bottom of the mechanical workpiece, and the arc-shaped rubber pad begins to deform under the elastic force of the rubber. The arc-shaped rubber pad is tightly pressed against the bottom edge of the mechanical workpiece, so as to prevent the edge of the mechanical workpiece from being damaged when the machining auxiliary platform clamps the mechanical workpiece.

[0017] (4) The present invention arranges a heating device so that the U-shaped rod, the rectangular box, the resistance heater, the double ring frame and the U-shaped copper tube cooperate with the heat collecting plate. The convex block drives the U-shaped rod to move toward the middle, the U-shaped rod drives the rectangular box to move toward the middle, the rectangular box drives the resistance heater to move toward the middle, the resistance heater transfers heat to the rectangular box, and the rectangular box transfers heat to the mechanical workpiece, thereby preventing the mechanical workpiece material on the machining auxiliary platform from expanding and contracting due to heat and causing inaccurate machining. In addition, the rectangular box drives the double ring frame to move toward the middle, the double ring frame drives the U-shaped copper tube to move toward the middle, the U-shaped copper tube drives the heat collecting plate to move toward the middle, and the heat collecting plate contacts the mechanical workpiece, so that the mechanical workpiece can be preheated quickly, thereby preventing the machining auxiliary platform from preheating the mechanical workpiece for too long, resulting in poor use effect of the auxiliary platform.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-11 One embodiment of the present invention is: a machining auxiliary platform, including a bottom plate 1, support legs 2 are fixed on both sides of the bottom surface of the bottom plate 1, a motor 3 is fixedly installed on the left side of the top surface of the bottom plate 1, triangular rings 7 are fixed on both sides of the top surface of the bottom plate 1, threaded rods 8 are rotatably installed on the inner walls of the two triangular rings 7, the rotating shaft of the motor 3 is fixed in the middle of the left side of the threaded rod 8, four L-shaped support plates 9 are fixed on both sides of the top surface of the bottom plate 1, two long rods 10 are fixed on the top of the opposite surfaces of the four L-shaped support plates 9, a protrusion 11 is rotatably installed on the left side of the outer wall of the threaded rod 8, and a protrusion 11 is meshed with the thread teeth of the threaded rod 8 in the positive direction Another protrusion 11 is rotatably installed on the right side of the outer wall of the threaded rod 8, and the other protrusion 11 is engaged with the thread teeth of the threaded rod 8 in the opposite direction. Protrusions 11 are slidably installed on both sides of the outer walls of the two long rods 10, and square openings are opened on the tops of the opposite surfaces of the two protrusions 11. T-shaped clamps 12 are fixed on the top surfaces of the two protrusions 11. Openings are opened in the middle of the opposite surfaces of the two T-shaped clamps 12. Two long strip openings are opened on the opposite surfaces of the two T-shaped clamps 12. The T-shaped clamps 12 can clamp smaller or thinner mechanical workpieces, avoiding the difficulty of processing smaller or thinner mechanical workpieces caused by the inconvenience of clamping the machining auxiliary platform.

[0022] An arc box 13 is passed through and fixed on the bottom of the opposite surfaces of the two T-shaped clamps 12, four short columns 14 are fixed on the opposite surfaces of the inner walls of the two arc boxes 13, two magnets 15 are fixed on the opposite surfaces of the four short columns 14, and the two magnets 15 are respectively arranged in the middle of the opposite surfaces of the arc boxes 13. The magnets 15 restrict the mechanical workpiece to prevent the mechanical workpiece on the machining auxiliary platform from being offset during machining and causing machining failure.

[0023] When in use, the supporting leg 2 supports the base plate 1, the staff puts the mechanical workpiece on the top of the base plate 1, and starts the motor 3 with an electric wire. The shaft of the motor 3 starts to rotate forward, the triangular ring 7 supports the threaded rod 8, and the shaft of the motor 3 drives the threaded rod 8 to rotate forward. The threaded rod 8 rotates forward in the triangular ring 7. At the same time, the L-shaped support plate 9 supports the long rod 10, and the threaded rod 8 drives the protrusion 11 to rotate forward. The protrusion 11 is restricted by the long rod 10. Under the action of the positive engagement of the thread teeth, one protrusion 11 slides to the right on the threaded rod 8 and drives the T-shaped clamping plate 12 to move to the right. Under the action of the reverse engagement of the thread teeth, the other protrusion 11 slides to the left on the threaded rod 8 and drives the T-shaped clamping plate 12 to slide to the left. Since one protrusion 11 is engaged with Another protrusion 11 can move to a fitting state, so that the T-shaped clamp 12 can clamp a smaller or thinner mechanical workpiece during the process of moving toward the middle. When processing mechanical workpieces in a workshop, the sizes of the mechanical workpieces are different. In the process of clamping the mechanical workpieces on the machining auxiliary platform, some mechanical workpieces are small or thin, which may cause inconvenience in clamping smaller and thinner mechanical workpieces. In the process of the T-shaped clamp 12 moving toward the middle, the gap caused by clamping is reduced, so that the T-shaped clamp 12 can clamp smaller or thinner mechanical workpieces, preventing the small or thin mechanical workpiece from causing inconvenience in clamping the auxiliary platform, thereby avoiding the problem of difficulty in processing smaller or thinner mechanical workpieces caused by inconvenience in clamping the machining auxiliary platform.

When the T-shaped clamp 12 clamps the workpiece, the magnet 15 contacts the surface of the mechanical workpiece. The magnet 15 is powered by an electric wire and is firmly adsorbed on the mechanical workpiece, so that the magnet 15 restricts the mechanical workpiece and prevents the mechanical workpiece from shifting during processing, thereby avoiding the problem of machining failure caused by the mechanical workpiece on the machining auxiliary platform shifting during machining.

[0025] See also Figure 1-11On the basis of the above embodiment, another embodiment of the present invention further includes an anti-deformation device 4, an anti-shake device 5 and a heating device 6, wherein an anti-deformation device 4 is arranged in the middle of the back sides of the two T-shaped clamps 12, and the anti-deformation device 4 includes two square shells 41, and the two square shells 41 are respectively fixed in the middle of the back sides of the two T-shaped clamps 12, and a plurality of cylinders 42 are fixedly installed on the opposite surfaces of the inner walls of the two square shells 41, and the inner walls of the two square shells 41 are fixed with porous rack plates 44, and the outer walls of the plurality of cylinders 42 are fixed with two porous rack plates 44, and the inner walls of the plurality of cylinders 42 are slidably installed with cylinders 43, and springs are arranged between the plurality of cylinders 43 and the plurality of cylinders 42, so that the irregular-shaped mechanical workpiece can be clamped by the machining auxiliary platform, so as to avoid the inconvenience of the machining auxiliary platform clamping the mechanical workpiece with a curved surface or an irregular shape, which causes difficulty in machining the special-shaped mechanical workpiece.

[0026] The anti-deformation device 4 also includes four concave arc strips 45, two concave arc strips 45 are respectively fixed on the opposite surfaces of the two square shells 41, and the four concave arc strips 45 are arranged in the long strip openings of the two T-shaped clamps 12. Two elastic coarse cloths 46 are slidably and fixedly installed in the grooves of the four concave arc strips 45, and rubber heads 47 are fixed on the opposite surfaces of the cylinders 43. The rubber heads 47 are respectively arranged on the opposite sides of the two elastic coarse cloths 46. The rough surface of the elastic coarse cloth 46 is wrapped on the mechanical workpiece. Under the action of friction, the mechanical workpiece is restricted from sliding, and the surface of the mechanical workpiece is prevented from slipping during the clamping process due to the smoothness of the surface.

The elastic coarse cloth 46 will not scratch the surface of the mechanical workpiece, and the mechanical processing auxiliary platform is prevented from scratching the surface of the mechanical workpiece when clamping the mechanical workpiece.

[0027] An anti-shake device 5 is arranged on both sides of the top surface of the bottom plate 1, and the anti-shake device 5 includes four arc-shaped support plates 51, which are fixed on both sides of the top surface of the bottom plate 1, and strip plates 52 are fixed on the top surfaces of the four arc-shaped support plates 51. The strip plates 52 are arranged inside the square openings of the two protrusions 11, and a rectangular opening is opened in the middle of the top surface of the strip plates 52. Two support columns 53 are fixed in the middle of the bottom surface of the strip plates 52, and the two support columns 53 are fixed on the top surface of the bottom plate 1. Arc-shaped spring sheets 54 are fixed at the bottom ends of the square openings of the two protrusions 11, and U-shaped frames 55 are fixed on the opposite surfaces of the two arc-shaped spring sheets 54. Rubber rollers 56 are rotatably installed on the front and rear sides of the inner walls of the two U-shaped frames 55, and the rubber rollers 56 are rotatably arranged on the top surfaces of the strip plates 52. The elastic coarse cloth 46 will not scratch the surface of the mechanical workpiece, so as to prevent the mechanical processing auxiliary platform from causing scratches on the surface of the mechanical workpiece when clamping the mechanical workpiece.

[0028] The anti-shake device 5 also includes two arc plates 57, which are respectively fixed on the top of the opposite surfaces of the two U-shaped frames 55. A number of rubber strips 58 are fixed to the outer walls of the two arc plates 57. Two arc-shaped rubber pads 59 are fixed to the top surfaces of the rubber strips 58. The elastic coarse cloth 46 will not scratch the surface of the mechanical workpiece, thereby preventing the mechanical processing auxiliary platform from causing scratches on the surface of the mechanical workpiece when clamping the mechanical workpiece.

[0029] A heating device 6 is provided on the top of the front and back sides of the two protrusions 11, and the heating device 6 includes four U-shaped rods 61, which are respectively fixed on the front and back sides of the two protrusions 11, and the four U-shaped rods 61 are arranged in an inverted eight shape, and two rectangular boxes 62 are fixed on the top of the opposite sides of the four U-shaped rods 61, and a resistance heater 63 is fixedly installed in the middle of the inner walls of the two rectangular boxes 62. The rectangular boxes 62 transfer heat to the mechanical workpiece to avoid thermal expansion and contraction of the mechanical workpiece material on the mechanical processing auxiliary platform, which causes inaccurate processing.

[0030] The heating device 6 also includes two double-ring frames 64, which are respectively fixed on the opposite surfaces of the two rectangular boxes 62. U-shaped copper tubes 65 are fixed on the inner walls of the two double-ring frames 64, and heat-collecting plates 66 are fixed on the opposite surfaces of the two U-shaped copper tubes 65. The two heat-collecting plates 66 are arranged above the T-shaped clamping plate 12, so that the mechanical workpiece can be preheated quickly, avoiding the mechanical processing auxiliary platform preheating the mechanical workpiece for too long, resulting in poor use effect of the auxiliary platform.

[0031] When the T-shaped clamping plate 12 moves toward the middle, the T-shaped clamping plate 12 drives the square shell 41 to move toward the middle, the square shell 41 drives the porous frame plate 44 to move toward the middle, the porous frame plate 44 drives the cylinder 42 to move toward the middle, the cylinder 42 drives the column 43 to move toward the middle, and the column 43 hits the mechanical workpiece in the process of moving toward the middle. Under the clamping force of the T-shaped clamping plate 12, the column 43 slides in the cylinder 42, and the spring in the cylinder 42, under the elastic force, allows the cylinder 43 to press tightly against the mechanical workpiece, and clamps the mechanical workpiece on the machining auxiliary platform. During the machining process, the surface of the mechanical workpiece may be an arc surface or an irregular shape. In the process of the cylinder 43 pressing against the surface of the mechanical workpiece, multiple cylinders 43 pressing against the surface of the mechanical workpiece can press against the arc surface or irregular surface of the mechanical workpiece according to different telescopic lengths, so that the irregular-shaped mechanical workpiece can be clamped by the machining auxiliary platform, preventing the mechanical workpiece with an arc surface or an irregular shape from being difficult to clamp, thereby avoiding the problem of difficulty in machining special-shaped mechanical workpieces caused by the inconvenience of the machining auxiliary platform clamping the mechanical workpiece with an arc surface or an irregular shape.

[0032] While the T-shaped clamping plate 12 drives the square shell 41 to move toward the middle, the square shell 41 drives the concave arc strip 45 to move toward the middle, and the concave arc strip 45 drives the elastic coarse cloth 46 to move toward the middle. At the same time, the cylinder 43 drives the rubber head 47 to move toward the middle, and the rubber head 47 presses against the elastic coarse cloth 46 to move toward the middle, and the elastic coarse cloth 46 contacts the surface of the workpiece, and the elastic coarse cloth 46 wraps the surface of the mechanical workpiece. The rubber head 47 presses against the elastic coarse cloth 46, and the rough surface of the elastic coarse cloth 46 wraps the mechanical workpiece. Under the action of friction, the mechanical workpiece is restricted from sliding, and the problem of slipping caused by the surface of the mechanical workpiece being too smooth during the clamping process is prevented. In order to maintain the integrity and quality of the mechanical workpiece during transportation, the surface of the mechanical workpiece is often coated with rust-proof paint. The protective solvents such as oil, etc., the protective solvents on the mechanical workpiece will adhere to the machining auxiliary platform. When used for a long time, the protective solvents will slowly accumulate in the equipment, causing a lot of oil on the surface of the equipment. The elastic coarse cloth 46 absorbs the protective solvents on the mechanical workpiece when wrapping the surface of the mechanical workpiece to prevent the protective solvents on the mechanical workpiece from accumulating on the equipment. When there is too much oil on the elastic coarse cloth 46, the staff can remove the elastic coarse cloth 46 for replacement. While the elastic coarse cloth 46 wraps the surface of the mechanical workpiece, the rubber head 47 rests on the elastic coarse cloth 46. When the elastic coarse cloth 46 restricts the mechanical workpiece, the elastic coarse cloth 46 will not scratch the surface of the mechanical workpiece, thereby avoiding the problem of scratches on the surface of the mechanical workpiece caused by the machining auxiliary platform when clamping the mechanical workpiece.

[0033] When the protrusion 11 moves toward the middle, the arc-shaped support plate 51 supports the strip plate 52, the support column 53 supports the strip plate 52, the strip plate 52 supports the mechanical workpiece, the protrusion 11 drives the arc-shaped spring sheet 54 to move toward the middle, the arc-shaped spring sheet 54 drives the U-shaped frame 55 to move toward the middle, the U-shaped frame 55 drives the rubber roller 56 to move toward the middle, the rubber roller 56 slides toward the middle on the strip plate 52, and the rubber roller 56 drives the U-shaped frame 55 to move to the bottom of the mechanical workpiece. When the mechanical workpiece is being processed, the mechanical workpiece will produce a certain vibration amplitude, and the clamped mechanical workpiece will produce a certain shaking at the bottom. The U-shaped frame 55 is tightly pressed against the bottom of the mechanical workpiece under the elastic force of the arc-shaped spring sheet 54 to prevent the mechanical workpiece from shaking at the bottom during processing, thereby avoiding the problem of poor workpiece finishing effect caused by the shaking of the bottom of the mechanical workpiece on the machining platform during processing.

[0034] While the arc spring sheet 54 drives the U-shaped frame 55 to move toward the middle, the U-shaped frame 55 drives the arc plate 57 to move toward the middle, the arc plate 57 drives the rubber strip 58 to move toward the middle, the rubber strip 58 drives the arc rubber pad 59 to move toward the middle, the arc rubber pad 59 contacts the bottom of the mechanical workpiece, and under the action of the rubber elastic force, the arc rubber pad 59 begins to deform, and the arc rubber pad 59 tightly presses against the bottom edge of the mechanical workpiece to prevent the bottom edge of the mechanical workpiece from being damaged when clamped, thereby avoiding the problem of damage to the edge of the mechanical workpiece caused by the machining auxiliary platform when clamping the mechanical workpiece.

[0035] While the protrusion 11 moves toward the middle, the protrusion 11 drives the U-shaped rod 61 to move toward the middle, the U-shaped rod 61 drives the rectangular box 62 to move toward the middle, and the rectangular box 62 drives the resistance heater 63 to move toward the middle. When the workshop performs mechanical processing in winter or the processed mechanical workpiece needs to be heated up, the resistance heater 63 is started with an electric wire, and the resistance heater 63 transfers heat to the rectangular box 62, and the rectangular box 62 transfers heat to the mechanical workpiece. When the temperature of the mechanical workpiece material changes, its volume will also change, reducing the thermal expansion and contraction of the mechanical workpiece material, which affects the processing accuracy, thereby avoiding the problem of inaccurate processing caused by the thermal expansion and contraction of the mechanical workpiece material on the machining auxiliary platform.
