Description

Technical Field

[0001] The invention belongs to the technical field of glass fiber reinforced plastic round bar grinding, and in particular relates to a grinding machine for glass fiber reinforced plastic round bars. Background Art

[0002] FRP round rods are made of glass fiber roving as reinforcement material and unsaturated polyester resin as matrix, and are pultruded into glass fiber rods. They are lightweight, high-strength, corrosion-resistant and colorful. FRP round rods need to be ground according to actual needs during production.

[0003] The existing Chinese utility model patent (CN220498581U) discloses a glass fiber reinforced plastic round rod production grinding machine, which places the glass fiber reinforced plastic round rod on a slide plate, and the two ends of the material are fitted with a baffle plate, so that the material keeps parallel to the rotating shaft when sliding down the slide plate to the curved plate. After the glass fiber reinforced plastic round rod enters the gap between the feeding turntable and the curved plate, the rotating feeding turntable drives the glass fiber reinforced plastic round rod to move until the glass fiber reinforced plastic round rod moves under the pressure plate, and the hydraulic cylinder is started to push the pressure plate downward until the rollers on both sides fix the glass fiber reinforced plastic round rod at the bottom of the curved plate, thereby restricting the glass fiber reinforced plastic round rod to the grinding station. The glass fiber reinforced plastic round rod rotates under the action of the feeding turntable, and is fully ground under the action of the grinding wheel. After the grinding is completed, the hydraulic cylinder is controlled to shrink, and the pressure plate drives the rollers on both sides to move upward, and the rotating feeding turntable continues to drive the glass fiber reinforced plastic round rod to move.

[0004] Although the above method can load and unload the FRP round rods by rotating the feeding turntable, it still needs to manually control the extension and contraction of the hydraulic cylinder to control the loading and unloading of the FRP round rods and limit the FRP round rods to the grinding station. The degree of automation is low, and the grinding of the FRP round rods still relies on manual control, which increases the labor intensity of the workers. In addition, the workers are under the condition of grinding FRP round rods for a long time, which affects the health of the workers. In addition, during the grinding process of the FRP round rods, the FRP round rods are not completely fixed. Therefore, the FRP round rods may move during the grinding process, and the length dimensional accuracy of the FRP round rods after grinding is poor. In summary, the above method cannot realize the loading of the FRP round rods, the adjustment of the grinding size of the FRP round rods, the automatic processing of grinding and unloading, and the grinding accuracy is poor.

Under the limiting effect of the rotating component 27, before and after the work station shaft 105 rotates, the opening direction of the U-shaped placement groove 106 is always away from the central axis of the cone-shaped shell 103; two clamping block slide grooves 107 are symmetrically arranged in the U-shaped placement groove 106, and the two clamping block slide grooves A fixed block 108 is slidably connected in each of 107, and one end of the fixed block 108 is set in a V shape and extends into the U-shaped placement groove 106; a tension spring 109 is fixedly connected in the clamping block slide groove 107, and the end of the tension spring 109 is fixedly connected to the fixed block 108. Under the tension of the tension spring 109, the fixed block 108 is located in the clamping block slide groove 107; an arc-shaped push block 114 is fixedly connected to one end of the vertical mounting plate 102 close to the truncated cone-shaped shell 103, and a transmission component 25 is provided on each of the five workstation shafts 105. When the workstation shaft 105 moves to coincide with the horizontal projection of the arc-shaped push block 114, the transmission component 25 overcomes the elastic force of the tension spring 109 force and drives the two fixed blocks 108 on the workstation shaft 105 to move synchronously toward each other; a rotating component 2 is arranged on the workbench 101, and a grinding head 112 is connected to the rotating component 2, and the grinding head 112 is located below the truncated cone shell 103, and the horizontal projection of the grinding head 112 and the arc-shaped push block 114 coincide with each other, and the rotating component 2 is used to drive the grinding head 112 to rotate, and a feed hopper 110, an arc-shaped support plate 113 and a discharge plate 111 are fixedly connected to the workbench 101, and the discharge end of the feed hopper 110 and the arc-shaped support plate 113 are both attached to the side wall of the truncated cone shell 103, and the arc-shaped support plate 113 is located below the feed hopper 110.

[0037] In the embodiment of the present invention, when in use, multiple FRP round rods are placed in the feed hopper 110. Under the guiding action of the feed hopper 110, the FRP round rods in the bottom layer are attached to the side wall of the truncated cone shell 103. Under the limiting action of the rotating component 27, the opening direction of the U-shaped placement groove 106 is away from the axis of the truncated cone shell 103, so that the FRP round rods in the feed hopper 110 can smoothly enter the U-shaped placement groove 106. The driving component 3 drives the fan-shaped tooth plate 115 to swing back and forth. When the fan-shaped tooth plate 115 swings to one side, the transmission component 14 drives the truncated cone shell 103 to rotate one-fifth of a circle counterclockwise, so that the U-shaped placement groove 106 containing the FRP round rods rotates downward.

When the planar projections coincide, the transmission component 2 5 overcomes the elastic force of the tension spring 109 and drives the two fixed blocks 108 on the station shaft 105 to move synchronously toward each other, so that the two fixed blocks 108 on the station shaft 105 clamp the FRP round rod, so that the FRP round rod and the station shaft 105 are coaxial; when the fan-shaped tooth plate 115 swings to the other side, the rotating component 2 7 drives the lowermost station shaft 105 to rotate, and the station shaft 105 drives the FRP round rod to rotate through the fixed block 108, and the rotating component 1 2 is used to drive the grinding head 112 to rotate, and the grinding head 112 grinds the rotating FRP round rod, thereby completing the grinding of the FRP round rod. During processing, as the truncated cone-shaped shell 103 rotates, the workstation shaft 105 moves to a point where it does not overlap with the horizontal projection of the arc-shaped push block 114, and the tension spring 109 pulls the fixed block 108 to retract into the clamping block slide slot 107, and the fixed block 108 releases the glass fiber reinforced plastic round rod, so that the ground glass fiber reinforced plastic round rod in the U-shaped placement groove 106 falls on the discharge plate 111, and under the guidance of the discharge plate 111, the ground glass fiber reinforced plastic round rod is unloaded; the reciprocating swing of the fan-shaped tooth plate 115 can drive the truncated cone-shaped shell 103 to switch the workstation once, so that the glass fiber reinforced plastic round rod in the feed hopper 110 enters the U-shaped placement groove 106 in turn, thereby realizing The automatic feeding of FRP round bars is realized; and before and after the FRP round bars are ground, the two fixed blocks 108 on the station shaft 105 can automatically clamp and release the FRP round bars, so that the FRP round bars are in a clamped state during the rotation process, thereby avoiding the displacement of the FRP round bars due to the grinding head 112 during the grinding process, thereby improving the grinding accuracy of the FRP round bars. Under the limiting effect of the rotating component 27, before and after the station shaft 105 rotates, the opening direction of the U-shaped placement groove 106 is always away from the axis of the truncated cone-shaped housing 103, which can ensure that the FRP round bars can smoothly enter the U-shaped placement groove 106 on the station shaft 105;The station switching of the truncated cone-shaped housing 103, in conjunction with the automatic clamping and loosening of the FRP round rod by the two fixed blocks 108 on the station shaft 105, can realize the grabbing and unloading of the FRP round rod, thereby improving the degree of automation of FRP round rod grinding, reducing the time of manual operation, reducing the labor intensity of workers, and also reducing the contact between workers and grinding dust, which is beneficial to the health of workers. ;

When the sliding block 502 cannot continue to move, the slider 602 will overcome the elastic force of spring four 603 and move relative to the sliding block 502. The elastic force of spring four 603 is greater than the elastic force of spring three 508, so that the moving distance of the sliding block 502 can be adjusted, so that the clamping position of the fixed block 108 can be adjusted, so that the fixed block 108 can clamp glass fiber reinforced plastic round rods of different diameters.

At this time, the opening direction of the U-shaped placement groove 106 is away from the axis of the truncated cone shell 103, which is convenient for the glass fiber reinforced plastic round rod to enter the U-shaped placement groove 106; when the fan-shaped tooth plate 115 swings to the other side, the fan-shaped tooth plate 115 drives the push plate 705 to move, the push plate 705 drives the push block 707 to move, and the push block 707 drives the guide sleeve 706 to move. The guide sleeve 706 overcomes the elastic force of spring five 704 and drives the rack 703 to move. The moving rack 703 drives gear two 701 to rotate, and gear two 701 drives the workstation shaft 105 to rotate until the inclined pushing section on the push rod 709 extends into the push hole 708 and pushes the other end of the push hole 708. The inclined pushing section on the push rod 709 pushes the push block 707 into the guide sleeve 706, so that the push block 707 does not contact the push plate 705. At this time, spring five 704 pushes the rack 703 to move in the opposite direction and reset, and gear two 701 drives the workstation shaft 105 to reverse and reset.

[0052] The above embodiment of the present invention provides a grinding machine for glass fiber reinforced plastic round bars. When in use, multiple glass fiber reinforced plastic round bars are placed in the feed hopper 110. Under the guidance of the feed hopper 110, the glass fiber reinforced plastic round bars at the bottom layer are attached to the side wall of the truncated cone-shaped housing 103. In the initial state, the spring 5 704 pushes the rack 703 so that the rack 703 is at one end of the rack slide groove 702, and the push rod 709 supports one end of the push hole 708, so that the push block 707 extends out of the guide sleeve 706.

During the swing, the gear 1 409 drives the meshing slider 403 to revolve, the revolving meshing slider 403 drives the ratchet 401 to rotate, the ratchet 401 drives the transmission shaft 408 to rotate, the transmission shaft 408 drives the truncated cone-shaped housing 103 to rotate one-fifth of a circle counterclockwise, so that the U-shaped placement groove 106 containing the glass fiber reinforced plastic round rod rotates downward. During this process, the arc-shaped support plate 113 blocks the opening of the U-shaped placement groove 106, thereby preventing the glass fiber reinforced plastic round rod in the U-shaped placement groove 106 from falling out, and the truncated cone-shaped housing 103 rotates one-fifth of a circle counterclockwise, so that the U-shaped placement groove 106 containing the glass fiber reinforced plastic round rod rotates downward. The housing 103 drives the station shaft 105 to revolve, and the station shaft 105 drives the push shaft 503 to revolve. When the push shaft 503 moves to contact the arc-shaped push block 114, the arc-shaped push block 114 overcomes the elastic force of the spring 3 508 and pushes the sliding block 502 and the push shaft 503 to move. The sliding block 502 drives the two push rods 506 to move synchronously. The two push rods 506 push the two wedge blocks 507 at the same time, so that the two wedge blocks 507 overcome the elastic force of the tension spring 109 and drive the two fixed blocks 108 to move synchronously. The two fixed blocks 108 clamp the FRP round rod because the clamping surface of the fixed block 108 is V-shaped and the two fixed blocks 108 move toward each other synchronously, so that the FRP round rod can be centered and clamped. The moving sliding block 502 drives the correction shaft 504 to move, and the correction shaft 504 pushes the FRP round rod to move in the U-shaped placement groove 106, so as to achieve the effect of correcting the front and rear positions of the FRP round rod, so that the length of the FRP round rod after grinding is consistent.When the sector tooth plate 115 swings to the other side, the sector tooth plate 115 drives the push plate 705 to move, the push plate 705 drives the push block 707 to move, the push block 707 drives the guide sleeve 706 to move, the guide sleeve 706 overcomes the elastic force of the spring five 704 and drives the rack 703 to move, the moving rack 703 drives the gear two 701 to rotate, the gear two 701 drives the station shaft 105 to rotate, until the inclined pushing section on the push rod 709 extends into the push hole 708 and pushes the other end of the push hole 708, the inclined pushing section on the push rod 709 pushes the push block 707 into the guide sleeve 706, so that the push block 707 does not contact the push plate 705, at this time, the spring five 704 pushes the rack 703 to move in the opposite direction and reset, Wheel 2 701 drives the workstation shaft 105 to reverse and reset, so that the workstation shaft 105 drives the FRP round rod to rotate through the fixed block 108. The rotating assembly 12 is used to drive the grinding head 112 to rotate. The grinding head 112 grinds the rotating FRP round rod, thereby completing the grinding process of the FRP round rod. As the truncated cone-shaped housing 103 rotates, the workstation shaft 105 moves to a position where it does not overlap with the horizontal projection of the arc-shaped push block 114. The tension spring 109 pulls the fixed block 108 to retract into the clamping block slide 107. The fixed block 108 releases the FRP round rod, so that the ground FRP round rod in the U-shaped placement groove 106 falls on the discharge plate 111. Under the guidance of the discharge plate 111, the ground FRP round rod is unloaded.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
