Description
Technical Field
[0001] The invention relates to the technical field of grinding and polishing thick metal plates, and more specifically to a gantry type automatic grinding machine for thick plates. Background Art
[0002] In the production process of stainless steel and other metal thick plates, common surface defects such as inclusions, scratches, pits, cracks, and scars will occur. In this regard, metal surface defects can be removed by grinding, which can improve product qualification rate, reduce losses, reduce costs, and increase product market competitiveness. At present, the surface grinding of stainless steel and special steel thick plates is carried out by manual grinding. Manual grinding is performed on each grinding point within the width of the plate on both sides of the plate width. Moreover, the upper surface is polished, and then the thick plate is flipped 180° by the plate turning machine before grinding the other surface. Its grinding efficiency and grinding quality are difficult to guarantee. At the same time, during the grinding process, the plate surface must be kept clean. Especially when the width of the thick plate is ≥2.5m, the grinding operation of the middle part of the plate width is very difficult. During the operation, it is inevitable that the plate surface will be contaminated, further affecting the grinding quality.
[0003] In order to improve the automation and intelligence level of on-site products and reduce the labor intensity of workers, the application of the thick plate intelligent surface grinding system can replace the current pure manual grinding with automatic grinding. However, the existing automatic grinding machines have various problems and cannot complete the grinding efficiently.

[0042] according to Figure 1-Figure 16 As shown, a gantry type automatic grinding machine for thick plates includes a thick plate support member and a thick plate grinding member, and the thick plate support member and the thick plate grinding member are correspondingly arranged on the ground. The thick plate support member includes a sliding support member and a thick plate straightening member, and the sliding support member is arranged on the ground, and the thick plate straightening member is arranged on the sliding support member. The sliding support member includes a sliding support seat, a sliding bearing seat and a sliding power member, and the sliding support seat is arranged on the ground, the sliding bearing seat is arranged on the sliding support seat, and the sliding power member is arranged on the sliding bearing seat. The sliding support seat includes a support seat 1 and a longitudinal slider 2, and a support leg is arranged on the bottom surface of the support seat 1, and the support seat 1 is fixed on the ground by the support leg. There are two support seats 1, and the two support seats 1 are distributed in parallel. The longitudinal slider 2 is in the shape of a dovetail block, and the two longitudinal sliders 2 are arranged one by one on the top surfaces of the two support seats 1.
[0043] The sliding bearing seat includes a longitudinal slide 3 and a transverse support member. The longitudinal slide 3 is in a rectangular block shape. A first dovetail groove is provided on the bottom surface of the longitudinal slide 3. The longitudinal slide 3 is buckled on the longitudinal slider 2 through the first dovetail groove at the bottom, so that the longitudinal slide 3 can slide longitudinally on the longitudinal slider 2. There are twenty-two longitudinal slides 3, and the twenty-two longitudinal slides 3 are evenly distributed on the two longitudinal sliders 2. The transverse support member includes a transverse support shaft 4, a bearing cylinder 5, a synapse transmission rod 6, a synapse top cone 7 and a synapse 8. The transverse support shaft 4 is in a thick-walled tubular shape. The two ends of the transverse support shaft 4 are horizontally penetrated on the longitudinal slides 3 located on the two longitudinal sliders 2, and the transverse support shaft 4 is circumferentially rotated and axially locked on the longitudinal slide 3. The transverse support shaft 4 is used to carry the thick metal plate 9 to be repaired. Furthermore, an anti-skid rubber sleeve 10 is sleeved on the transverse support shaft 4, and the anti-skid rubber sleeve 10 is axially locked with the transverse support shaft 4. The anti-skid rubber sleeve 10 can increase the friction between the transverse support shaft 4 and the metal thick plate 9 after being adjusted to the correct position.
[0044] The bearing cylinder 5 is fixedly arranged on one end of the transverse support shaft 4, and the piston rod of the bearing cylinder 5 is inserted into the tube of the transverse support shaft 4, and the axis of the bearing cylinder 5 coincides with the axis of the transverse support shaft 4.

The synaptic transmission rod 6 reciprocates along the axial direction with the expansion and contraction of the bearing cylinder 5. The synaptic top-up cone 7 is in the shape of a cone, and the large end diameter of the synaptic top-up cone 7 is smaller than the inner diameter of the transverse support shaft 4. The synaptic top-up cone 7 is fixedly mounted on the synaptic transmission rod 6. There are eleven synaptic top-up cones 7, and the eleven synaptic top-up cones 7 are evenly distributed on the synaptic transmission rod 6 along the axial direction. The synapse 8 is in the shape of a rod, and the length of the synapse 8 is greater than the wall thickness of the transverse support shaft 4. One end of the synapse 8 penetrates the thick wall of the transverse support shaft 4 along the radial direction of the transverse support shaft 4, and penetrates the anti-slip rubber sleeve 10. Forty-four synapses 8 are provided, and the forty-four synapses 8 are evenly distributed around the eleven synapse lifting cones 7. When the bearing cylinder 5 is extended, it will drive the synapse transmission rod 6 to move to the right, and the synapse transmission rod 6 will drive the synapse lifting cone 7 to move to the right. The synapse lifting cone 7 moving to the right will push the synapse 8 outward, and the free end of the pushed synapse 8 will protrude from the anti-slip rubber sleeve 10 to support the metal thick plate 9. Since the synapse 8 and the metal thick plate 9 are point contacts between metals, it is convenient for the metal thick plate 9 to be positioned correctly, so as to facilitate the positioning and automatic grinding of the metal thick plate 9 by the thick plate grinding part. When the thick plate straightening member straightens the position of the metal thick plate 9, the bearing cylinder 5 contracts, and then drives the synapse lifting table 7 to move to the left through the synapse transmission rod 6, so as to facilitate the retraction of the synapse 8 into the transverse support shaft 4, so that the metal thick plate 9 is in contact with the anti-slip rubber sleeve 10, and the anti-slip rubber strip is used to prevent the metal thick plate 9 from being displaced longitudinally during the grinding process.
[0045] The transverse support members are provided in eleven sets, and the eleven sets of the transverse support members are provided corresponding to the longitudinal slide seats 3 on the two longitudinal slide blocks 2.

The longitudinal follower tube 13 is sleeved on the transmission shaft 12, and the first slider on the longitudinal follower tube 13 cooperates with the first slide groove on the transmission shaft 12, so that the longitudinal follower tube 13 can move longitudinally and lock circumferentially on the transmission shaft 12. The longitudinal follower plate 14 is in the shape of a right-angle plate, and a right-angle end of the longitudinal follower plate 14 is sleeved on the longitudinal follower tube 13, so that the longitudinal follower tube 13 can rotate circumferentially on the longitudinal follower plate 14. The other right-angle end of the longitudinal follower plate 14 is sleeved on the other end of the transverse support shaft 4, so that the transverse support shaft 4 can rotate circumferentially on the longitudinal follower plate 14.

When the first magnetic coil is fed with positive direct current to generate a magnetic field, it will push the driven gear 16 to move outward in the axial direction to mesh with the driving gear 15, thereby driving the transverse support shaft 4 to rotate circumferentially. When the first magnetic coil is fed with reverse direct current to generate a magnetic field, it will pull the driven gear 16 to move inward in the axial direction to disengage from the driving gear 15. The first gear 17 is fixedly sleeved on the other end of the transverse support shaft 4, and the first rack 18 is fixedly arranged on the support seat 1, and the first rack 18 is meshed with the first gear 17. When the transverse support shaft 4 is driven by the first motor 11, the first gear 17 will be driven to rotate, and the rotating first gear 17 will move longitudinally on the first rack 18, thereby pushing the longitudinal slide 3 to move longitudinally on the longitudinal slide 2. Eleven sets of longitudinal push transmission members are provided, and the eleven sets of longitudinal push transmission members correspond to the eleven transverse support shafts 4 one by one. The supporting position of the transverse support shaft 4 on the lower surface of the metal thick plate 9 can be controlled by controlling the direction of the direct current supplied to the first magnetic coil, so as to meet the grinding operation of the thick plate grinding member on the lower surface of the metal thick plate 9.

One end of the second transmission tube 22 is sleeved on the other end of the first transmission tube 21, and the third slider on one end of the second transmission tube 22 cooperates with the third slide groove on the first transmission tube 21, so that the second transmission tube 22 can be locked circumferentially and moved axially on the first transmission tube 21; one end of the third transmission tube 23 is embedded in the free end tube of the second transmission tube 22, and the fourth slide groove on the third transmission tube 23 cooperates with the fourth slider on the other end of the second transmission tube 22, so that the third transmission tube 23 can be locked circumferentially and moved axially on the second transmission tube 22, and the other end of the third transmission tube 23 is connected to the second gear 20 of the alignment power transmission member in the longitudinal slide 3 arranged at an adjacent position.
