[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 5 , the gantry mechanism 100 comprises: a gantry support 11 and a first lifting mechanism 12 and a second lifting mechanism 13 connected to the gantry support 11, wherein the first lifting mechanism 12 and the second lifting mechanism 13 are parallel to each other and vertically arranged; the first lifting mechanism 12 and the second lifting mechanism 13 both comprise a double-track drive unit. The lifting mechanism of the gantry mechanism 100 of the multifunctional grinding and polishing equipment of this embodiment adopts a double-guide rail drive unit, which greatly improves the stability of the grinding and polishing tool operation and the accuracy of the lifting action, and is beneficial to the grinding and polishing quality and effect of the automated multifunctional grinding and polishing equipment.

[0042] like Figure 2As shown, the gantry support 11 includes: a first column 112, a second column 113, and a cross arm 111 whose two ends are respectively connected to the top of the first column 112 and the second column 113; the first lifting mechanism 12 is connected to the first column 112, and the second lifting mechanism 13 is connected to the second column 113. The first column 112, the second column 113 and the cross arm 111 together form an inverted U-shaped support frame mechanism, that is, a roughly gantry structure.

Specifically, the axial direction of the flange plate 142 is perpendicular to the lifting direction of the first lifting mechanism 12, and the disk surface of the flange plate 142 is horizontally arranged toward one side of the second lifting mechanism 13. In this embodiment, the first driving unit 122 is a rotation driving module such as a servo motor.

[0046] Since the gantry mechanism 100 of the multifunctional grinding and polishing equipment is used for the lifting and rotating actions of the grinding and polishing tools, there must be particles such as debris generated by grinding and polishing during the grinding and polishing of the workpiece. In order to improve the smooth operation and service life of the first lifting mechanism 12 and the second lifting mechanism 13, the first lifting mechanism 12 also includes an upper folding protective cover 124 connected to the upper edge of the first connecting member 125, and a lower folding protective cover 123 connected to the lower edge of the first connecting member 125. Specifically, the upper folding protective cover 124 and the lower folding protective cover 123 are both accordion-type protective covers. The driven flange unit 14 follows the first connecting member 125, and is controlled by the first driving unit 121 to lift and lower along the first guide rail unit 122, and the top edge of the upper folding protective cover 124 is fixedly connected to the top of the first column 112, and the lower edge of the lower folding protective cover 123 is fixedly connected to the bottom of the first column 112. During the synchronous lifting and lowering process of the first connecting member 125 and the driven flange unit 14, the upper foldable protective cover 124 and the lower foldable protective cover 123 both follow the first connecting member 125 to extend and retract in the vertical direction, thereby keeping the internal structure of the first lifting mechanism 12 always inside the variable sealing protective cover composed of the first connecting member 125, the upper foldable protective cover 124 and the lower foldable protective cover 123, thereby preventing external grinding and polishing debris from entering and damaging the track, affecting its smoothness and service life.

[0048] The upper edge of the second connecting member 132 is further connected to an upper foldable protective cover 134 , and the lower edge of the second connecting member 132 is further connected to a lower foldable protective cover 133 .

[0049] In this embodiment, the upper foldable protective cover 134 and the lower foldable protective cover 133 are both accordion-type protective covers.

The flange driver 151 is vertically arranged on the second column 113, and the rotation direction of the active flange 153 is horizontal, so the right-angle commutator 152 is used for transmission commutation between the two to realize the right-angle commutation of the power of the flange driver 151. The second connecting member 132 is also provided with a drag chain 154, which is used to set the wire electrically connected to the servo motor.

[0051] Please refer again Figure 5 The second guide rail unit 131 includes: a longitudinal guide rail 1311 (1312) and at least two sliders 1313 (1314) slidably connected to the longitudinal guide rail 1311, the slider 1313 is also connected to the second connecting member 132, and the longitudinal guide rail 1311 is connected to the second column 113.

[0052] The longitudinal guide rails 1311 and 1312 are fixedly connected to the second column 113 and are distributed in parallel on both sides of the second screw rod 126. A screw rod seat 138 is also provided on the second screw rod 136, and the screw rod seat 138 is also connected to the second connecting member 132, so as to convert the rotational power of the second screw rod 136 into vertical lifting power. The second screw rod 136 is also provided with an upper shaft seat 137 near the upper end and a lower shaft seat near the lower end, and the second screw rod 136 is rotatably plugged into the upper shaft seat 137 and the lower shaft seat. The second drive unit 135, the second guide rail unit 131, the second screw rod 136, the screw rod seat 138, the upper shaft seat 137, and the lower shaft seat form a screw drive module. In this embodiment, the second drive unit 135 and the flange drive member 151 are both servo motors.

[0053] Please refer again Figure 1 The first lifting mechanism 12 and the second lifting mechanism 13 connected to the gantry bracket 11 are used to drive the driven flange unit 14 and the active flange unit 15 to synchronously lift and lower, respectively. The driven flange unit 14 and the active flange unit 15 are arranged opposite to each other, and a grinding and polishing tool, such as a rough grinding tool and a fine grinding tool, is arranged between the two. The two ends of the grinding and polishing tool are connected to the driven flange 142 and the active flange 153 by screws. When the angle of the grinding and polishing tool needs to be adjusted, the flange driving unit 151 is controlled to start, and the active flange 153 is driven to rotate a certain angle through the right-angle commutator 152, so as to achieve the angle adjustment of the grinding and polishing tool.

[0054] See also Figures 6 to 11The long-stroke moving mechanism 200 includes: a base 21, an X-direction moving component 22 connected to the base 21, and a Y-direction moving component 23 connected to the X-direction moving component 22; wherein the X-direction moving component 22 and the Y-direction moving component 23 reciprocate in two mutually perpendicular directions, and the X-direction moving component 22 and the Y-direction moving component 23 are both driven by a dual-track drive unit. In this embodiment, the X-direction and the Y-direction can be understood as the X-axis and the Y-axis in the Cartesian coordinate system, which are mutually perpendicular directions. wherein the X-direction moving component 22 and the Y-direction moving component 23 are both driven by a dual-track drive unit, which has better stability and a smoother moving process, so that the angle and distance between them and the polishing tool can be accurately controlled to improve the polishing quality.

[0055] Please refer again Figure 7 and Figure 8 The X-axis moving component 22 includes: a first linear driving unit 221, a first guiding unit 222 arranged parallel to the first linear driving unit 221, and a telescopic protective cover arranged outside the first linear driving unit 221 and the first guiding unit 222.

The two guide rails 2221 are parallel to the screw rod 2212 and are distributed on both sides of the screw rod 2212 at equal intervals, wherein at least two sliders 2222 are arranged on the guide rails 2221, and the sliders 2222 are connected to the Y-direction moving assembly 23. The single guide rail 2221 is provided with at least two sliders 2222, which can improve the reliability and stability of the slider 2222 and the Y-direction moving assembly 23 connected to the slider 2222. At the same time, the double guide rails 2221 design distributed on the outside of the screw rod 2212 is adopted to further improve the reliability and smoothness of the linear reciprocating movement of the X-direction moving assembly 22. The use of a driving motor such as a servo motor can accurately control its moving stroke, thereby ultimately improving the quality of the grinding and polishing process. In this embodiment, the telescopic protective cover is an armor-type protective cover.

[0058] Specifically, the armor-type protective cover includes: a first armor protective cover 223 and a second armor protective cover 224, the proximal ends of the first armor protective cover 223 and the second armor protective cover 224 are connected to the Y-axis moving component 23, and the relatively distant ends of the first armor protective cover 223 and the second armor protective cover 224 are both connected to the base 21. That is, the first armor protective cover 223 and the second armor protective cover 224 are respectively connected to the two opposite ends of the Y-axis moving component 23 in the moving direction, and when the Y-axis moving component 23 is controlled by the X-axis moving component 22 to drive the reciprocating movement, the first armor protective cover 223 and the second armor protective cover 224 are synchronously extended and retracted, and the first linear drive unit 221 and the first guide unit 222 are always covered inside the protective cover, so as to prevent external waste chips from entering and protect the internal components from being damaged by the accumulation of waste chips.

[0059] Please refer again Figures 9 to 11 The Y-axis moving component 23 includes: a connecting seat 231, a second linear driving unit 237 and a second guiding unit 236 connected to the connecting seat 231, a mounting seat 232 controlled by the linear reciprocating movement of the second linear driving component 237, and a protective cover arranged on the outside of the second linear driving unit 237 and the second guiding unit 236.

[0060] The second linear drive unit 237 adopts the same screw drive structure as the first linear drive unit 221 , and the second guide unit 236 also adopts the same double guide rail structure as the first guide unit 222 .

[0061] The protective cover includes: a protective cover plate 233 and a telescopic protective cover located below the protective cover plate 233. Specifically, the telescopic protective cover is an accordion-type protective cover.

[0062] The telescopic protective cover includes: a first accordion-type protective cover 234 and a second accordion-type protective cover 235, the proximal ends of the first accordion-type protective cover 234 and the second accordion-type protective cover 235 are connected to the mounting seat 232, and the relatively far ends of the first accordion-type protective cover 234 and the second accordion-type protective cover 235 are both connected to the connecting seat 231. The workpiece clamping mechanism 300 is connected to the mounting seat 232, and a connecting portion 2311 is provided at the bottom of the connecting seat 231, and the connecting portion 2133 is connected to the screw seat 2214 of the X-axis moving component 22.

[0063] Please refer again Fig.11 As can be seen from the partially enlarged schematic diagram, a gap is reserved between the outer edge of the protective cover plate 233 and the connecting seat 231 below. The mounting seat 232 is located below the protective cover plate 233, and the side extends out from the gap. The edges of the first accordion-type protective cover 234 and the second accordion-type protective cover 235 are respectively connected to the mounting seat 232. When the mounting seat 232 is controlled by the second linear drive unit 237 to reciprocate along the second guide unit 236, the first accordion-type protective cover 234 and the second accordion-type protective cover 235 are synchronously driven to telescope, thereby always keeping the internal components of the Y-axis moving assembly 23 in a closed state to prevent waste chips from entering during the grinding and polishing process and damaging the internal components. A protective cover plate 233 is added on the top of the first accordion-type protective cover 234 and the second accordion-type protective cover 235 to further improve the protective function of the protective cover. The waste chips dropped during grinding and polishing accumulate on the protective cover plate 233, which is also convenient for cleaning.

[0064] Please refer again Figure 12 to Figure 14 The workpiece clamping mechanism 300 includes: a deflection base unit, a loading base unit 34 driven to deflect by the deflection base unit, and at least one group of chuck units 35 connected to the loading base unit 34, wherein the chuck units 35 include a self-rotation driving module 351, which is used to drive the chuck units 35 to rotate and synchronously drive the workpiece 001 to rotate. In this embodiment, the chuck units 35 are provided with two groups, and the other group is the chuck units 36. It can be understood that in other embodiments, the number of the chuck units 35 (36) can be increased or decreased according to actual needs, and a workpiece 001 is fixed on each chuck unit 35 (36).

[0065] Taking the chuck unit 35 as an example, the chuck unit 35 includes an expansion chuck mechanism and the self-rotation drive module 351 driving the expansion chuck mechanism, and the self-rotation drive module 351 is connected to the loading base unit 34. The expansion chuck mechanism refers to fixing the workpiece 001 by contracting the structural member expansion machine, so as to facilitate loading and unloading the workpiece 001 from the expansion chuck mechanism. Generally speaking, the workpiece clamping mechanism 300 of this embodiment is used for grinding and polishing the surface of the workpiece 001, so the expansion chuck mechanism adopts an expansion method of expanding or contracting from the inside of the workpiece 001 to fix the workpiece.

[0066] The expansion chuck mechanism includes: a chuck 352, a connecting rod 353 inserted into the chuck 352, an elastic member 354 sleeved on the connecting rod 353, and a push rod 355 connected to the lower end of the connecting rod 353; wherein the top of the chuck 352 is a multiple clamping block 3521 enclosed structure that can be expanded outward, the top of the connecting rod 353 is an inverted cone head 3531, and the top of the elastic member 354 abuts against the inverted cone head 3531. The bottom end of the conical head 3531 abuts against the push rod 355; when the connecting rod 353 is forced to move toward the top of the clamping head 352, the inverted conical head 3531 is separated from the clamping block 3521, and the elastic member 354 is compressed, so that the multiple clamping blocks 3521 shrink inward; conversely, when the external force is released, the elastic member 354 pushes the connecting rod 353 to reset, so that the inverted conical head 3531 expands the clamping block 3521. A through hole 3520 is provided inside the clamping head 352 in the longitudinal direction, and the connecting rod 353 is inserted into the through hole 3520.

[0067] like Fig.13 The workpiece 001 is a pipe, and the lumen of the workpiece 001 is inserted downward from the top of the clamp 352. After the connecting rod 353 is released, the clamp block 3521 is expanded outward by the inverted cone head 3531, thereby clamping and fixing the workpiece 001 from inside the lumen.
