Description
Technical Field
[0001] This utility model relates to the field of CNC grinding machine technology, and in particular to a CNC grinding machine capable of continuously and alternately grinding rolls. Background Technology
[0002] Rolls are key components in steel rolling production. Their surface quality and precision directly affect the quality of steel. After long-term use, defects such as wear and scratches will appear on the surface of the rolls. Grinding is required to restore their dimensional accuracy, shape accuracy and surface roughness in order to ensure that the rolls can continue to work stably and efficiently and produce steel products that meet quality requirements.
[0003] Traditional roll grinding machines can typically grind only one roll at a time. After grinding one roll, the machine needs to be stopped for loading and unloading operations before grinding the next roll. This process involves a long auxiliary time, resulting in low overall production efficiency. This is especially true in large-scale roll processing applications, where it is difficult to meet production schedule requirements. Therefore, we have introduced a new CNC grinding machine that can continuously and alternately grind rolls. Utility Model Content
[0004] The main objective of this invention is to provide a CNC grinding machine capable of continuously and alternately grinding rolls, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A CNC grinding machine capable of continuously and alternately grinding rolls includes a worktable with a grinding groove at its upper end. Guide grooves are formed on the left and right sides of the lower groove wall. Two displacement mechanisms are slidably connected within the two guide grooves. Drive seats are fixedly connected to the upper middle parts of the left and right groove walls. A No. 1 motor is fixedly installed on the right wall of the drive seat. A threaded rod is fixedly installed at the output end of the No. 1 motor. A slider is movably connected to the outer surface of the threaded rod. A limit strip is fixedly connected to the lower part of the outer surface of the slider. A cylinder is fixedly installed at the lower end of the limit strip. The output end of the cylinder is fixedly connected to the grinding mechanism.
[0007] Preferably, the displacement mechanism includes a displacement seat and a fixed plate. Guide strips are fixedly connected to the lower left and lower right parts of the displacement seat. Vertical plates are fixedly connected to the upper left and upper right parts of the displacement seat. A second motor is fixedly installed on the left end of the left vertical plate. A roller body is installed on the output end of the second motor through a rotating shaft. Extension plates are fixedly connected to the lower left and lower right parts of the displacement seat. Two fixed plates are provided, and electric push rods are fixedly installed at the front ends of both fixed plates.
[0008] Preferably, the displacement seat is located inside the grinding groove, and the lower end of the displacement seat does not contact the lower wall of the grinding groove, and the two guide strips are slidably connected to the two guide grooves respectively.
[0009] By adopting the above technical solution, the guide bar slides in the guide groove, enabling the displacement seat to maintain a stable displacement.
[0010] Preferably, the lower ends of both fixed plates are fixedly connected to the lower wall of the grinding groove, and the output ends of the two electric push rods are fixedly connected to the two extension plates respectively.
[0011] By adopting the above technical solution, the electric push rod can push the extension plate to move, thereby enabling the displacement seat to move and the roll body to move below the grinding block.
[0012] Preferably, the grinding mechanism includes a fixed block and a locking block. The fixed block has a locking groove at its lower end. The locking groove has positioning grooves at both the front and rear of its inner wall. The fixed block has a first threaded hole on both the left and right sides of its outer surface. A knob is threaded into each of the first threaded holes. The locking block has a positioning strip fixedly connected to both the front and rear of its outer surface. The locking block has a second threaded hole on both the left and right sides of its outer surface. A grinding block is fixedly connected to the lower end of the locking block.
[0013] Preferably, the upper end of the fixing block is fixedly connected to the output end of the cylinder, the locking block is engaged with the locking groove, and the two positioning strips are engaged with the two positioning grooves respectively.
[0014] By adopting the above technical solution, two positioning strips are respectively inserted into two positioning grooves, so that the positions of the two No. 2 threaded holes and the two No. 1 threaded holes can be quickly aligned, thereby improving installation efficiency.
[0015] Preferably, the two No. 2 threaded holes correspond to the positions of the two No. 1 threaded holes, and the ends of the two knobs are threadedly connected to the two No. 2 threaded holes.
[0016] By adopting the above technical solution, the grinding block can be installed and fixed by connecting two knobs into two No. 2 threaded holes.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. By setting up a displacement mechanism, two electric push rods are activated, which push the extension plate to move. The extension plate is connected to the displacement seat, so that the displacement seat can move the front-mounted roll body to the bottom of the grinding block for grinding. While the front roll body is being ground, the rear roll body can be installed and wait. After the front roll body is finished grinding, it is reset to the front, and the rear-mounted roll body is moved to the bottom of the grinding block for grinding. This allows the roll bodies to be ground continuously and alternately, reducing downtime. Through continuous alternating grinding, the CNC grinding machine can continuously output ground rolls, avoiding production line shutdowns due to insufficient roll supply and ensuring the efficient operation of the entire production process.
[0019] 2. By setting up a grinding mechanism, the clamping block is inserted into the slot from below the fixed block, and the two positioning strips are simultaneously inserted into the two positioning slots, so that the positions of the two No. 1 threaded holes and the two No. 2 threaded holes can be quickly aligned. Then, the two knobs are screwed into the No. 1 threaded holes and No. 2 threaded holes, making it easy to install and replace the grinding block. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:
[0029] A CNC grinding machine capable of continuously and alternately grinding rolls includes a worktable 1. A grinding groove 2 is provided on the upper end of the worktable 1. Guide grooves 3 are provided on the left and right sides of the lower groove wall of the grinding groove 2. Two displacement mechanisms 4 are slidably connected in the two guide grooves 3. Drive seats 5 are fixedly connected to the upper middle part of the left groove wall and the upper middle part of the right groove wall of the grinding groove 2. A No. 1 motor 6 is fixedly installed on the right wall of the drive seat 5. A threaded rod 7 is fixedly installed at the output end of the No. 1 motor 6. A slider 8 is movably connected to the outer surface of the threaded rod 7. A limit slide 9 is fixedly connected to the lower part of the outer surface of the slider 8. A cylinder 10 is fixedly installed at the lower end of the limit slide 9. A grinding mechanism 11 is fixedly connected to the output end of the cylinder 10.
[0030] In this embodiment, the displacement mechanism 4 includes a displacement seat 41 and a fixing plate 42. Guide bars 43 are fixedly connected to the lower left and lower right parts of the displacement seat 41. Vertical plates 44 are fixedly connected to the upper left and upper right parts of the displacement seat 41. A second motor 45 is fixedly installed on the left end of the left vertical plate 44. The output end of the second motor 45 is mounted on a roller body 46 through a rotating shaft. Extension plates 47 are fixedly connected to the lower left and lower right parts of the displacement seat 41. There are two fixing plates 42. Electric push rods 48 are fixedly installed at the front ends of the two fixing plates 42. The displacement seat 41 is located in the grinding groove 2, and the lower end of the displacement seat 41 does not contact the lower groove wall of the grinding groove 2. The two guide bars 43 are slidably connected to the two guide grooves 3 respectively. The lower ends of the two fixing plates 42 are fixedly connected to the lower groove wall of the grinding groove 2. The output ends of the two electric push rods 48 are fixedly connected to the two extension plates 47 respectively.
[0031] The above scheme involves activating two electric push rods 48, which push the extension plate 47 to move. The extension plate 47 is connected to the displacement seat 41, allowing the displacement seat 41 to move the front-mounted roll body 46 to the underside of the grinding block 119 for grinding. While the front roll body 46 is grinding, the rear roll body 46 can be installed and waited for. After the front roll body 46 finishes grinding, it is reset to the front, and the rear-mounted roll body 46 is moved to the underside of the grinding block 119 for grinding. This allows the roll bodies 46 to be ground continuously and alternately.
[0032] In this embodiment, the grinding mechanism 11 includes a fixed block 111 and a locking block 112. The fixed block 111 has a locking groove 113 at its lower end. Positioning grooves 114 are provided on both the front and rear sides of the inner wall of the locking groove 113. A first-order threaded hole 115 is provided on both the left and right sides of the outer surface of the fixed block 111. A knob 116 is threaded into each of the two first-order threaded holes 115. Positioning strips 117 are fixedly connected to both the front and rear sides of the outer surface of the locking block 112. The outer surface of the locking block 112... The left side of the face and the right side of the outer surface are both provided with No. 2 threaded holes 118. The lower end of the locking block 112 is fixedly connected to the grinding block 119. The upper end of the fixing block 111 is fixedly connected to the output end of the cylinder 10. The locking block 112 is engaged with the locking groove 113. The two positioning strips 117 are engaged with the two positioning grooves 114 respectively. The two No. 2 threaded holes 118 correspond to the positions of the two No. 1 threaded holes 115 respectively. The ends of the two knobs 116 are threadedly connected to the two No. 2 threaded holes 118 respectively.
[0033] The above solution involves inserting the locking block 112 into the slot 113 from below the fixing block 111, and simultaneously inserting the two positioning strips 117 into the two positioning slots 114, so that the positions of the two No. 1 threaded holes 115 and the two No. 2 threaded holes 118 can be quickly aligned. Then, the two knobs 116 are screwed into the No. 1 threaded holes 115 and No. 2 threaded holes 118, making it easy to install and replace the grinding block 119.
[0034] It should be noted that this utility model is a CNC grinding machine capable of continuously and alternately grinding rolls. During use, two electric push rods 48 are started, which rotate and push the extension plate 47 to generate displacement. Since the extension plate 47 is connected to the displacement seat 41, the displacement seat 41, driven by the extension plate 47, carries the pre-installed roll body 46 to move directly below the grinding block 119. Subsequently, the first motor 6 is started, which drives the threaded rod 7 to rotate, allowing the slider 8 to move left and right along the threaded rod 7, thereby driving the grinding block 119 to move left and right. At the same time, the control cylinder 10 pushes downward, causing the grinding block 119 to contact the roll body 46 and begin the grinding operation. While the front roll body 46 is being ground, the rear roll body 46 can be installed in advance and placed in a standby state. After the front roll body 46 has finished grinding, it is reset to its initial position, and then the rear pre-installed roll body 46 is moved... The displacement seat 41 moves to below the grinding block 119 to continue the grinding operation. In this way, the front and rear roll bodies 46 can be ground alternately, reducing equipment downtime. Through this continuous alternating grinding method, the CNC grinding machine can continuously output ground rolls, avoiding production line shutdowns due to insufficient roll supply, and effectively ensuring the efficient and stable operation of the entire production process. In addition, when installing the grinding block 119, the locking block 112 is inserted into the locking groove 113 from below the fixing block 111, while ensuring that the two positioning strips 117 are accurately inserted into the corresponding two positioning grooves 114. This operation can quickly align the two No. 1 threaded holes 115 with the two No. 2 threaded holes 118. After that, simply rotate the two knobs 116 to screw them into the No. 1 threaded holes 115 and No. 2 threaded holes 118 respectively to easily complete the installation of the grinding block 119. If the grinding block 119 needs to be replaced later, the operation is equally convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
