A laterally movable worktable and a longitudinally movable mounting seat are installed on the machine body. A rotatable shaft workpiece is clamped on the clamping assembly. The grinding disc is rotatably mounted on the mounting seat. A grinding ring is provided on the edge of the grinding disc. The outer cylindrical surface of the grinding ring is an outer cylindrical grinding surface. The two end surfaces of the grinding ring are end surface grinding surfaces. The outer cylindrical grinding surface is in contact with the outer cylindrical surface of the shaft workpiece for grinding, and the two end surface grinding surfaces are in contact with the two end surfaces of the shaft workpiece for grinding. The device improves work efficiency and grinding accuracy, but in actual use, the device cannot control the grinding component to grind the object according to the length of the object to be ground, and the grinding length of the grinding component can only be manually controlled by the staff. Summary of the invention

[0004] The main purpose of the present invention is to provide a high-precision cylindrical grinding device and process for metal composite materials, which can effectively solve the problem that the grinding length of the grinding component can only be manually controlled by the staff and the grinding length of the grinding component cannot be controlled according to the required length of the grinding object.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A high-precision cylindrical grinding device for metal composite materials, comprising a workbench, a fixing device is arranged at the upper end of the workbench, a mounting platform is arranged at one side of the outer surface of the workbench, a cylindrical grinding mechanism is arranged at the middle part of the upper end of the mounting platform, a braking device is arranged at the lower part of the mounting platform, and a transmission device is arranged at one side of the outer surface of the mounting platform;

[0007] The fixing device includes a slide plate, and a braking mechanism and a fixing mechanism are slidably installed on both sides of the upper end of the slide plate. The middle parts of the lower ends of the braking mechanism and the fixing mechanism are threadedly connected to the threaded rod in the middle part of the slide plate, and the outer surfaces of the braking mechanism and the fixing mechanism are provided with a braking rod on one side close to the external cylindrical grinding mechanism.

[0008] Specifically, before performing external cylindrical grinding on the metal composite material, the staff needs to place the metal composite material between the braking mechanism and the fixing mechanism of the workbench, lift the braking device, and then rotate the threaded rod in the middle of the slide to move the braking mechanism and the fixing mechanism toward each other, so that the braking mechanism and the fixing mechanism fix the metal composite material. After fixation, the staff lowers the braking device, and then adjusts the external cylindrical grinding mechanism so that the grinding head of the external cylindrical grinding mechanism contacts the surface of the metal composite material, and then starts the external cylindrical grinding mechanism and the braking mechanism, so that the external cylindrical grinding mechanism drives the grinding head to rotate to grind the surface of the metal composite material. At the same time, the braking mechanism will drive the metal composite material to rotate, so that the external cylindrical grinding mechanism can comprehensively grind the surface of the metal composite material.

[0009] Furthermore, in the process of the braking mechanism driving the metal composite material to rotate, the braking mechanism drives the external cylindrical grinding mechanism to reciprocate through the transmission device and the mounting table, so that the external cylindrical grinding mechanism can repeatedly grind the surface of the metal composite material until it is ground to the requirements. During this process, the braking device can limit the reciprocating range of the external cylindrical grinding mechanism.

[0010] Preferably, the mounting platform includes a mounting plate, a mounting hole is penetrated through the middle part of the upper end of the mounting plate, a screw is rotatably installed in the middle part of the upper end of the mounting plate, a mounting block is slidably installed in the middle part of the upper end of the mounting plate, the upper end of the mounting block is fixedly connected to the lower end of the external cylindrical grinding mechanism, and the middle part of the mounting block is threadedly connected to the middle part of the outer surface of the mounting plate.

[0011] Preferably, the transmission device comprises a mounting shell, the mounting shell is fixedly mounted on the outer surface of the mounting plate, a spur gear 1 and a spur gear 4 are arranged at the upper part of the inner cavity of the mounting shell, the middle parts of the spur gear 1 and the spur gear 4 are fixedly connected to the outer surface of the screw, a spur gear 2 and a gear set are arranged at the middle part of the inner cavity of the mounting shell, the spur gear 2 and the central axis of the gear located at the upper part of the gear set are colinear, a spur gear 3 is arranged at the lower part of the inner cavity of the mounting shell, and the spur gear 3 is connected to the transmission rod at the lower part of the brake mechanism through a belt transmission mechanism;

[0012] The spur gear 2 can be meshed and connected with the spur gear 4 and the spur gear 3, and the gear set can be meshed and connected with the spur gear 1 and the spur gear 3.

[0013] Specifically, when the braking mechanism drives the metal composite material to rotate, the braking mechanism drives the spur gear three to rotate through the belt transmission mechanism. When the spur gear three rotates, the gear set or spur gear two meshing with the spur gear three can respectively drive the screw to rotate forward or reverse through the spur gear one and the spur gear four. Which of the gear set and the spur gear four is meshing with the spur gear three is controlled by the braking device.

[0014] Furthermore, when the spur gear three is meshed with the spur gear two, the screw rotates forward, and at this time, the screw drives the external cylindrical grinding mechanism to move toward the side close to the fixing mechanism through the mounting block. When the brake device controls the gear set to mesh with the spur gear three, the screw rotates reversely, and at this time, the screw drives the external cylindrical grinding mechanism to move toward the side close to the brake mechanism through the mounting block.

[0015] Preferably, the braking device includes a pull rod, and positioning pieces are provided on both sides of the lower end of the pull rod, and push plates are provided on the sides where the two positioning pieces are close to each other, and the two push plates are respectively fixedly installed on both sides of the lower end of the mounting block, and a pull handle is provided at the lower part of the two positioning pieces and the two push plates, and the pull handle is rotatably installed on the lower part of the mounting plate.

[0016] Preferably, the positioning member includes an elastic telescopic rod, the upper end of the elastic telescopic rod is fixedly connected to the lower end of the pull rod, the middle part of the outer surface of the elastic telescopic rod is slidably connected to the inner surface of the brake rod, the lower end of the elastic telescopic rod is provided with an arc rod, and an arc positioning plate is slidably installed on the side of the outer surface of the arc rod close to the push plate, a positioning rod 2 is provided on the upper part of the arc positioning plate, and the positioning rod 2 is slidably installed on the lower part of the elastic telescopic rod, and a limiting hole is provided on the side of the outer surface of the elastic telescopic rod away from the push plate, and the positioning rod 2 is adapted for use with the limiting hole.

[0017] Preferably, the pull handle includes a positioning rod 1, which is rotatably mounted on the lower end of the mounting plate, and the upper array of the positioning rod 1 is provided with a positioning groove, and the outer surface of the positioning rod 1 is sleeved with a mounting rod on the side close to the transmission device, and the inner cavity of the mounting rod is provided with a spring fixedly connected to the end face of the positioning rod 1, and the outer surface of the mounting rod is fixedly connected to the middle of the spur gear 2 and the gear in the upper and middle part of the gear set.

[0018] Specifically, when spur gear three is meshed with spur gear two and connected with the screw rod, the screw rod drives the external cylindrical grinding mechanism to move toward the side close to the fixing mechanism through the mounting block. When the mounting block drives the external cylindrical grinding mechanism to move to the side close to the fixing mechanism, the push plate at the lower end of the mounting block close to the side of the fixing mechanism will contact the surface of the arc-shaped positioning plate in the positioning member on this side, and then the push plate will push the arc-shaped positioning plate to move, so that the positioning rod two is inserted into the inner cavity of the limiting hole. At this time, the arc-shaped positioning plate cannot move up and down, and then the arc-shaped positioning plate drives the positioning rod one to move through the positioning groove in the process of being pushed by the push plate, and then the positioning rod one pulls the spur gear two and the gear set to move toward the side close to the fixing mechanism through the mounting rod, so that the gear set is meshed with spur gear three, thereby reversing the screw rod and positioning the member.

[0019] Furthermore, in the process that the arc-shaped positioning plate on the side close to the fixing mechanism drives the installation shell spur gear 2 and the gear group to move through the positioning rod 1, the limiting hole on the upper part of the arc-shaped positioning plate on the side close to the braking mechanism is not inserted into the inner cavity of the limiting hole on this side. Therefore, when the positioning rod 1 moves, the arc-shaped positioning plate on this side will move up and down under the action of the positioning groove, thereby causing the elastic telescopic rod on this side to perform telescopic movement, but it will not hinder the arc-shaped positioning plate on the side close to the fixing mechanism from pulling the positioning rod 1 to move.

[0020] Furthermore, when the cylindrical grinding mechanism moves to the side close to the braking mechanism, the process is the same, but at this time, when the positioning rod moves, it will first pull the arc-shaped positioning plate close to the fixing mechanism side to restore to its initial state, and then move under the action of the positioning groove.

[0021] Furthermore, in the process of fixing the metal composite material by the braking mechanism and the fixing mechanism, the braking rods on the braking mechanism and the fixing mechanism will respectively drive the positioning pieces on both sides to move, so that the distance between the positioning pieces on both sides can be adjusted according to the length of the metal composite material. At the same time, the distance between the positioning pieces on both sides and the mounting blocks is the length of the metal composite material.

[0022] The present invention also discloses a grinding process using the above-mentioned high-precision cylindrical grinding device of the metal composite material, and the specific steps are as follows:

[0023] S1. Before performing external cylindrical grinding on the metal composite material, the worker needs to place the metal composite material between the braking mechanism and the fixing mechanism of the workbench, lift the braking device, and then rotate the threaded rod in the middle of the slide to move the braking mechanism and the fixing mechanism toward each other, so that the braking mechanism and the fixing mechanism fix the metal composite material;

[0024] S2. After the metal composite material is fixed, the staff lowers the brake device, then adjusts the external cylindrical grinding mechanism so that the grinding head of the external cylindrical grinding mechanism contacts the surface of the metal composite material, then starts the external cylindrical grinding mechanism and the brake mechanism, so that the external cylindrical grinding mechanism drives the grinding head to rotate to grind the surface of the metal composite material, and the brake mechanism drives the metal composite material to rotate;

[0025] S3. In the process of the brake mechanism driving the metal composite material to rotate, the brake mechanism drives the cylindrical grinding mechanism to reciprocate through the transmission device and the mounting table, so that the cylindrical grinding mechanism can repeatedly grind the surface of the metal composite material;

[0026] S4. When the transmission device and the mounting platform drive the cylindrical grinding mechanism to move, the braking device can limit the reciprocating range of the cylindrical grinding mechanism, so that the cylindrical grinding mechanism can reciprocate according to the length of the metal composite material.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, a mounting platform and a transmission device are provided. When the brake mechanism drives the metal composite material to rotate, the brake device controls the meshing of different gears in the transmission device, so that the transmission device can drive the cylindrical grinding mechanism to reciprocate through the mounting platform, so that the cylindrical grinding mechanism can fully grind the surface of the metal composite material, thereby improving the reliability of the device.

[0029] 2. In the present invention, by providing a braking device, when the mounting table drives the external cylindrical grinding mechanism to move, the braking device uses the push of the external cylindrical grinding mechanism to control the meshing of different gears in the transmission device. At the same time, the braking device can also limit the reciprocating motion distance of the external cylindrical grinding mechanism when the staff fixes the rotation of the metal composite material through the braking mechanism and the fixing mechanism, thereby improving the stability of the device.

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1, as Figure 1 and Figure 2 As shown, this embodiment discloses a high-precision external cylindrical grinding device for metal composite materials, including a workbench 1, a fixing device 2 is arranged at the upper end of the workbench 1, a mounting table 3 is arranged on one side of the outer surface of the workbench 1, an external cylindrical grinding mechanism 5 is arranged in the middle of the upper end of the mounting table 3, a braking device 6 is arranged at the lower part of the mounting table 3, and a transmission device 4 is arranged on one side of the outer surface of the mounting table 3.

[0041] Furthermore, the fixing device 2 includes a slide plate 21, and a braking mechanism 22 and a fixing mechanism 23 are slidably installed on both sides of the upper end of the slide plate 21, and the middle parts of the lower ends of the braking mechanism 22 and the fixing mechanism 23 are threadedly connected to the threaded rod in the middle part of the slide plate 21, and a braking rod 24 is provided on the outer surface of the braking mechanism 22 and the fixing mechanism 23 on the side close to the external cylindrical grinding mechanism 5.

[0042] Specifically, before performing external cylindrical grinding on the metal composite material, the staff needs to place the metal composite material between the braking mechanism 22 and the fixing mechanism 23 of the workbench 1, lift the braking device 6, and then rotate the threaded rod in the middle of the slide 21 to move the braking mechanism 22 and the fixing mechanism 23 toward each other, so that the braking mechanism 22 and the fixing mechanism 23 fix the metal composite material. After fixation, the staff puts down the braking device 6, and then adjusts the external cylindrical grinding mechanism 5 so that the grinding head of the external cylindrical grinding mechanism 5 contacts the surface of the metal composite material, and then starts the external cylindrical grinding mechanism 5 and the braking mechanism 22, so that the external cylindrical grinding mechanism 5 drives the grinding head to rotate to grind the surface of the metal composite material. At the same time, the braking mechanism 22 will drive the metal composite material to rotate, so that the external cylindrical grinding mechanism 5 can fully grind the surface of the metal composite material.

[0043] Furthermore, in the process of the braking mechanism 22 driving the metal composite material to rotate, the braking mechanism 22 drives the external cylindrical grinding mechanism 5 to reciprocate through the transmission device 4 and the mounting table 3, so that the external cylindrical grinding mechanism 5 can repeatedly grind the surface of the metal composite material until it is ground to the required level. During this process, the braking device 6 can limit the reciprocating range of the external cylindrical grinding mechanism 5.

[0044] In order to place the cylindrical grinding mechanism 5, the cylindrical grinding mechanism 5 can be driven to move under the action of the transmission device 4, so that the cylindrical grinding mechanism 5 performs cylindrical grinding on the metal composite material fixed on the fixing device 2, such as Figure 2 As shown, the mounting platform 3 includes a mounting plate 31, a mounting hole is penetrated through the middle part of the upper end of the mounting plate 31, a screw rod 32 is rotatably installed in the middle part of the upper end of the mounting plate 31, a mounting block 33 is slidably installed in the middle part of the upper end of the mounting plate 31, the upper end of the mounting block 33 is fixedly connected to the lower end of the external cylindrical grinding mechanism 5, and the middle part of the mounting block 33 is threadedly connected to the middle part of the outer surface of the mounting plate 31.

[0045] In order to drive the cylindrical grinding mechanism 5 to operate through the mounting table 3, as shown in FIG. Figure 3 and Figure 4 As shown, the transmission device 4 includes a mounting shell 41, which is fixedly mounted on the outer surface of the mounting plate 31, and a spur gear 1 42 and a spur gear 46 are arranged at the upper part of the inner cavity of the mounting shell 41, and the middle parts of the spur gear 1 42 and the spur gear 46 are fixedly connected to the outer surface of the screw rod 32, and a spur gear 2 43 and a gear set 44 are arranged at the middle part of the inner cavity of the mounting shell 41, and the central axes of the spur gear 2 43 and the gears located at the upper part of the gear set 44 are colinear, and a spur gear 3 45 is arranged at the lower part of the inner cavity of the mounting shell 41, and the spur gear 3 45 is connected to the transmission rod at the lower part of the braking mechanism 22 through a belt transmission mechanism.

[0046] Further, spur gear two 43 can be meshed and connected with spur gear four 46 and spur gear three 45, and gear set 44 can be meshed and connected with spur gear one 42 and spur gear three 45.

[0047] Specifically, when the brake mechanism 22 drives the metal composite material to rotate, the brake mechanism 22 drives the spur gear three 45 to rotate through the belt transmission mechanism. When the spur gear three 45 rotates, the gear set 44 or the spur gear two 43 meshing with the spur gear three 45 can respectively drive the screw 32 to rotate forward or reverse through the spur gear one 42 and the spur gear four 46. Which of the gear set 44 and the spur gear four 46 is meshed with the spur gear three 45 is controlled by the brake device 6.

[0048] Furthermore, when the spur gear three 45 is meshed and connected with the spur gear two 43, the screw 32 rotates forward, and the screw 32 drives the external cylindrical grinding mechanism 5 to move toward the side close to the fixing mechanism 23 through the mounting block 33. When the braking device 6 controls the gear set 44 to mesh with the spur gear three 45, the screw 32 reverses, and the screw 32 drives the external cylindrical grinding mechanism 5 to move toward the side close to the braking mechanism 22 through the mounting block 33.

[0049] In order to enable the transmission device 4 to drive the outer cylindrical grinding mechanism 5 to reciprocate through the mounting table 3, the outer cylindrical grinding mechanism 5 can repeatedly grind the outer cylindrical surface of the metal composite material until the metal composite material is ground to a corresponding size, such as Figure 5 and Figure 6 As shown, the braking device 6 includes a pull rod 61, and positioning members 62 are provided on both sides of the lower end of the pull rod 61. Push plates 63 are provided on the sides where the two positioning members 62 are close to each other. The two push plates 63 are respectively fixedly installed on both sides of the lower end of the mounting block 33. A pull handle 64 is provided at the lower part of the two positioning members 62 and the two push plates 63, and the pull handle 64 is rotatably installed at the lower part of the mounting plate 31.

[0050] Further, such as Figure 7 As shown, the positioning member 62 includes an elastic telescopic rod 621, the upper end of the elastic telescopic rod 621 is fixedly connected to the lower end of the pull rod 61, the middle part of the outer surface of the elastic telescopic rod 621 is slidably connected to the inner surface of the brake rod 24, and the lower end of the elastic telescopic rod 621 is provided with an arc rod 622, and the outer surface of the arc rod 622 is slidably installed with an arc positioning plate 623 on the side close to the push plate 63, and the upper part of the arc positioning plate 623 is provided with a second positioning rod 624, and the second positioning rod 624 is slidably installed on the lower part of the elastic telescopic rod 621, and the outer surface of the elastic telescopic rod 621 is away from the push plate 63. A limiting hole 625 is provided, and the second positioning rod 624 is adapted for use with the limiting hole 625.

[0051] Further, such as Figure 8 As shown, the pull handle 64 includes a positioning rod 641, which is rotatably mounted on the lower end of the mounting plate 31. The upper array of the positioning rod 641 is provided with a positioning groove 642. The outer surface of the positioning rod 641 is close to the transmission device 4 and is sleeved with a mounting rod 643. The inner cavity of the mounting rod 643 is provided with a spring fixedly connected to the end face of the positioning rod 641. The outer surface of the mounting rod 643 is fixedly connected to the middle of the spur gear 2 43 and the gear in the upper middle part of the gear set 44.

[0052] Specifically, when the spur gear three 45 is meshed with the spur gear two 43 to connect the screw rod 32 and rotate forward, the screw rod 32 drives the outer cylindrical grinding mechanism 5 to move toward the side close to the fixing mechanism 23 through the mounting block 33. When the mounting block 33 drives the outer cylindrical grinding mechanism 5 to move to the side close to the fixing mechanism 23, the push plate 63 at the lower end of the mounting block 33 close to the side of the fixing mechanism 23 will contact the surface of the arc-shaped positioning plate 623 in the positioning member 62 on this side, and then the push plate 63 will push the arc-shaped positioning plate 623 to move. The positioning rod 2 624 is inserted into the inner cavity of the limiting hole 625. At this time, the arc positioning plate 623 cannot move up and down, so that the arc positioning plate 623 drives the positioning rod 1 641 to move through the positioning groove 642 during the process of being pushed by the push plate 63, and then the positioning rod 1 641 pulls the spur gear 2 43 and the gear set 44 to move to the side close to the fixing mechanism 23 through the mounting rod 643, so that the gear set 44 is meshed with the spur gear 3 45, thereby reversing the screw rod 32 and the positioning member 62.

[0053] Furthermore, in the process that the arc-shaped positioning plate 623 on the side close to the fixing mechanism 23 drives the spur gear 2 43 and the gear set 44 of the mounting shell 41 to move through the positioning rod 1 641, the limiting hole 625 on the upper part of the arc-shaped positioning plate 623 on the side close to the braking mechanism 22 is not inserted into the inner cavity of the limiting hole 625 on this side. Therefore, when the positioning rod 1 641 moves, the arc-shaped positioning plate 623 on this side will move up and down under the action of the positioning groove 642, thereby making the elastic telescopic rod 621 on this side perform telescopic movement, but it will not hinder the arc-shaped positioning plate 623 on the side close to the fixing mechanism 23 from pulling the positioning rod 1 641 to move.

[0054] Furthermore, when the cylindrical grinding mechanism 5 moves to the side close to the braking mechanism 22, the process is the same, but at this time, when the positioning rod 641 moves, it will first pull the arc positioning plate 623 close to the side of the fixing mechanism 23 to restore to its initial state, and then move under the action of the positioning groove 642.

[0055] Furthermore, in the process of fixing the metal composite material by the braking mechanism 22 and the fixing mechanism 23, the braking rods 24 on the braking mechanism 22 and the fixing mechanism 23 will respectively drive the positioning members 62 on both sides to move, so that the distance between the positioning members 62 on both sides can be adjusted according to the length of the metal composite material. At the same time, the distance between the positioning members 62 on both sides and the mounting block 33 is the length of the metal composite material.

[0056] Embodiment 2: This application also discloses a method for using a high-precision cylindrical grinding device for metal composite materials, and the specific steps are as follows:

[0057] S1. Before performing cylindrical grinding on the metal composite material, the worker needs to place the metal composite material between the braking mechanism 22 and the fixing mechanism 23 of the workbench 1, lift the braking device 6, and then rotate the threaded rod in the middle of the slide plate 21 to move the braking mechanism 22 and the fixing mechanism 23 toward each other, so that the braking mechanism 22 and the fixing mechanism 23 fix the metal composite material;

[0058] S2. After the metal composite material is fixed, the staff puts down the brake device 6, and then adjusts the outer cylindrical grinding mechanism 5 so that the grinding head of the outer cylindrical grinding mechanism 5 contacts the surface of the metal composite material, and then starts the outer cylindrical grinding mechanism 5 and the brake mechanism 22, so that the outer cylindrical grinding mechanism 5 drives the grinding head to rotate to grind the surface of the metal composite material, and the brake mechanism 22 drives the metal composite material to rotate;

[0059] S3. In the process of the brake mechanism 22 driving the metal composite material to rotate, the brake mechanism 22 drives the cylindrical grinding mechanism 5 to reciprocate through the transmission device 4 and the mounting platform 3, so that the cylindrical grinding mechanism 5 can repeatedly grind the surface of the metal composite material;

[0060] S4. When the transmission device 4 and the mounting platform 3 drive the cylindrical grinding mechanism 5 to move, the braking device 6 can limit the reciprocating range of the cylindrical grinding mechanism 5, so that the cylindrical grinding mechanism 5 can reciprocate according to the length of the metal composite material.

[0061] It should be noted that the specific installation method, circuit arrangement and connection method, and control method of the braking mechanism 22 and the cylindrical grinding mechanism 5 used in the above-mentioned embodiment 1 are conventional designs in the prior art and will not be elaborated in detail in the present invention.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
