However, in actual situations, there is a certain error in the initial thickness of each plate. Since the position of the grinding roller cannot be adjusted, the thickness will be different during the grinding process, affecting the accuracy of grinding.

[0049] Example 1

[0050] In order to solve the above problems, this embodiment discloses a fully automatic thickness measuring six-axis grinding machine, the structure of which is as follows: Figures 1 to 6 As shown, the grinding machine includes a frame 100, a main control module, a thickness measuring mechanism 101 installed on the frame 100, a cooling mechanism 102, three first grinding mechanisms 103, and three second grinding mechanisms 201. The three first grinding mechanisms 103 and the three second grinding mechanisms 201 are arranged alternately.

[0051] The first grinding mechanism 103 includes a first lifting drive mechanism 104, a first grinding drive mechanism 108, and a first grinding wheel 113 and a first parallel wheel 114 arranged vertically; the second grinding mechanism 201 includes a second lifting drive mechanism 202, a second grinding drive mechanism 203, a second grinding wheel 204 arranged coplanar with the second parallel wheel 205, and a second parallel wheel 205 arranged coplanar with the first grinding wheel 113; the injection end of the cooling mechanism 102 is directly facing between the first grinding wheel 113 and the first parallel wheel 114 and between the second grinding wheel 204 and the second parallel wheel 205;

[0052] The first grinding drive mechanism 108 is used to drive the first grinding wheel 113 to rotate, the first lifting drive mechanism 104 is used to drive the first grinding drive mechanism 108 and the first grinding wheel 113 to rise and fall simultaneously so that the first grinding wheel 113 is close to or away from the first parallel wheel 114, the second grinding drive mechanism 203 is used to drive the second grinding wheel 204 to rotate, and the second lifting drive mechanism 202 is used to drive the second grinding drive mechanism 203 and the second grinding wheel 204 to rise and fall simultaneously so that the second grinding wheel 204 is close to or away from the second parallel wheel 205;

[0053] The main control module is respectively connected to the cooling mechanism 102 , the thickness measuring mechanism 101 , the first grinding drive mechanism 108 , the first lifting drive mechanism 104 , the second lifting drive mechanism 202 and the second grinding drive mechanism 203 by signals.

[0054] from Figure 1 It can be seen that the plates are put in from the feed end of the frame 100. The feed end of the frame 100 is an external feed roller module 401. The external feed roller module 401 is coplanar with the first grinding wheel 113 and the first parallel wheel 114 to ensure parallel input of the plates.

[0055] The first thickness measuring mechanism 101 is arranged between the external feeding roller module 401 and the first first grinding mechanism 103 to measure the thickness of the incoming plate. In this embodiment, the thickness measuring mechanism 101 is composed of rollers arranged up and down, springs and contact sensors. Under normal circumstances, the springs are in a relaxed state. When the plate enters the rollers arranged up and down and squeezes the upper rollers away, the upper rollers squeeze the springs and contact the contact sensors at the same time, thereby achieving the effect of measuring the thickness of the plate.

[0056] After the plate is measured by the thickness measuring mechanism 101, it enters the first first grinding mechanism 103 for grinding. Specifically, the first grinding drive mechanism 108 includes a grinding drive motor 109, a grinding drive belt 110, a grinding support seat 111 and a grinding rotation fixed seat 112, the grinding support seat 111 is fixedly arranged on the frame 100, the grinding rotation fixed seat 112 is connected to the grinding support seat 111 in a sliding manner up and down, the first grinding wheel 113 is rotatably arranged on the grinding rotation fixed seat 112, and the grinding drive motor 109 is drivingly connected to the first grinding wheel 113 through the grinding drive belt 110;

[0057] The first lifting drive mechanism 104 includes a lifting drive motor 105, a lifting output electric cylinder 106 and a lifting connecting rod 107. The output end of the lifting drive motor 105 is drivingly connected to the input end of the lifting output electric cylinder 106. The output end of the lifting output electric cylinder 106 is connected to the grinding rotating fixed seat 112 through the lifting connecting rod 107.

[0058] In this embodiment, the grinding drive motor 109 drives the first grinding wheel 113 to rotate through the grinding drive belt 110 to grind the plate; in addition, the lifting drive motor 105 drives the lifting connecting rod 107 to lift and lower by outputting to the lifting output electric cylinder 106, so as to drive the grinding rotating fixed seat 112 to lift and lower to achieve the effect of controlling the lifting and lowering of the first grinding wheel 113.

[0059] Furthermore, the first grinding drive mechanism 108 also includes a motor mounting plate 115, a lifting guide column 116, a first compression spring 117 and a second compression spring 118, the grinding drive motor 109 is mounted on the motor mounting plate 115, the lifting guide column 116 is mounted on the frame 100, the motor mounting plate 115 is slidably connected to the lifting guide column 116, the first compression spring 117 and the second compression spring 118 are respectively sleeved on the lifting guide column 116, the two ends of the first compression spring 117 are respectively connected to the upper end of the lifting guide column 116 and the upper end surface of the motor mounting plate 115, and the two ends of the second compression spring 118 are respectively connected to the lower end of the lifting guide column 116 and the lower end surface of the motor mounting plate 115. Since the position of the lifting output electric cylinder 106 in this embodiment is fixed, the lifting drive motor 105 will move up and down relative to the lifting output electric cylinder 106 during output.

[0060] At the same time, in the initial state (i.e., the first grinding wheel 113 is in contact with the first parallel wheel 114), the lifting drive motor 105 is in the lowest position (equivalent to the lifting drive motor 105 being the farthest away from the lifting output electric cylinder 106), the lower end of the lifting drive motor 105 is pressed against the upper end of the grinding drive motor 109 and makes the first compression spring 117 in a stretched state, the second compression spring 118 in a compressed state, and the grinding drive belt 110 is also in a taut state; when the lifting drive motor 105 drives the first grinding wheel 113 to rise, the lifting drive motor 105 approaches the direction of the lifting output electric cylinder 106, and under the action of the first compression spring 117 and the second compression spring 118, the grinding drive motor 109 follows the lifting drive motor 105 to rise, so that the grinding drive belt 110 is always in a taut state, ensuring the normal connection between the grinding drive motor 109 and the first grinding wheel 113.

[0061] In addition, the first grinding drive mechanism 108 also includes a lifting transmission rod 121 and a right-angle reducer 122. The number of the lifting output electric cylinder 106, the lifting connecting rod 107, the grinding support seat 111 and the grinding rotating fixed seat 112 are all two. A single lifting output electric cylinder 106, the lifting connecting rod 107, the grinding support seat 111 and the grinding rotating fixed seat 112 form a group of up and down adjustment components, and the two groups of up and down adjustment components are respectively installed on both sides of the frame 100; the two ends of the lifting transmission rod 121 are respectively connected to the input ends of the two lifting output electric cylinders 106, and the lifting drive motor 105 is connected to the lifting transmission rod 121 through the right-angle reducer 122. By arranging the same up and down adjustment components on both sides of the frame 100, the lifting drive motor 105 is output to the two lifting output electric cylinders 106 through the right-angle reducer 122 and the lifting transmission rod 121, so as to drive the two ends of the first grinding wheel 113 at the same time, so as to ensure that the grinding drive motor 109 and the first grinding wheel 113 are evenly stressed.

[0062] Specifically, the first grinding drive mechanism 108 further includes a left-right lateral movement motor 119 and a lateral movement base plate 120. The first grinding wheel 113 is rotatably arranged on the lateral movement base plate 120, and the lateral movement base plate 120 is horizontally slidably connected to the grinding rotating fixed seat 112. The left-right lateral movement motor 119 is installed on the grinding rotating fixed seat 112, and the left-right lateral movement motor 119 is drivingly connected to the lateral movement base plate 120. In this embodiment, the left-right lateral movement of the first grinding wheel 113 is realized by setting the left-right lateral movement motor 119, so as to realize the horizontal grinding of the plate.

[0063] It should be noted that, in this embodiment, the structures of the first grinding mechanism 103 and the second grinding mechanism 201 are substantially the same, and the only difference is that the first grinding mechanism 103 and the second grinding mechanism 201 are mirror-symmetrical. This has the advantage that the lifting drive mechanisms and grinding drive mechanisms on both sides can be staggered to achieve the effect of saving space.

[0064] Specifically, the fully automatic thickness measuring six-axis grinding machine also includes a conveying mechanism 301 installed on the frame 100, the conveying mechanism 301 includes a conveying drive motor 302, a plurality of coplanar conveying and pressing wheel groups 303, and a plurality of transmission bars 308 drivingly connected to adjacent conveying and pressing wheel groups 303, the conveying drive motor 302 drivingly connected to the transmission bar 308 between two random adjacent conveying and pressing wheel groups 303; the conveying and pressing wheel group 303 includes a pressing wheel 304, a conveying wheel 305, a pressing wheel seat 306 and a pressing spring 307, the conveying wheel 305 is rotatably arranged on the frame 100 and connected to the corresponding transmission bar 308, the pressing wheel seat 306 is installed on the frame 100, the pressing wheel 304 is rotatably slidable up and down on the pressing wheel seat 306, and the pressing spring 307 is connected between the wheel handle of the pressing wheel 304 and the pressing wheel seat 306.

[0065] In this embodiment, the plate passes through the pressing wheel 304 to cause the pressing spring 307 to be compressed, thereby increasing the friction between the plate and the conveying wheel 305; the transmission bar 308 is preferably a chain, and the above-mentioned external feed roller module 401, thickness measuring mechanism 101, conveying wheel 305, first parallel wheel 114 and second parallel wheel 205 are all arranged with coaxially rotating gears to mesh with the chain to achieve the conveyance of the plate.
