And by starting the second electric telescopic rod, the polishing block can be driven to rotate around the bottom end of the fixed rod to adjust the angle, which is convenient for polishing different angles of the object, has a good angle adjustment function, and improves the comprehensiveness of polishing.

[0004] Although the angle of the polishing machine can be adjusted in the above application, when the polishing block is rotated by the electric telescopic rod, the telescopic distance of the electric push rod is prone to deviation, resulting in inaccurate adjustment of the angle of the polishing block and affecting the polishing effect.

[0005] Therefore, a polishing device for hardware part processing is proposed to solve the above problems. Content of the Utility Model

[0007] The present utility model achieves the above object through the following technical solutions. A polishing device for hardware part processing includes: a base, on the top of which two fixing plates are slidably connected. An installation frame is fixedly connected to the top of the base, and an electric push rod is fixedly connected to the top of the installation frame. The bottom end of the electric push rod penetrates through the installation frame and is provided with an adjustment mechanism. Among them, the adjustment mechanism includes a mounting plate fixedly connected to the bottom end of the electric push rod. One side of the mounting plate is rotatably connected with a rotating shaft. One end of the rotating shaft penetrates through the mounting plate and is rotatably connected with a large gear.

A spring is fixedly connected between the other end of the round plate and the inner wall of the round rod. A plurality of annularly distributed clamping holes are formed in the inner wall of the circular ring. The other end of the round plate is fixedly connected with a pull rod, and the other end of the pull rod penetrates through the spring and the round rod on one side. The clamping of the clamping rod and the clamping hole ensures the stability when the small gear and the large gear rotate synchronously. Under the action of the pull rod, the round plate, the spring, and the connecting rod, when it is necessary to rotate the small gear to release the clamping of the clamping rod and the clamping hole, the staff only needs to pull the pull rod.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Specifically in implementation: As Figures 1-5 shown, a polishing device for hardware part processing includes: a base 1, on the top end of the base 1, two fixing plates 2 are slidably connected, on the top end of the base 1, a mounting frame 3 is fixedly connected, on the top end of the mounting frame 3, an electric push rod 4 is fixedly connected, and the bottom end of the electric push rod 4 penetrates through the mounting frame 3 and is provided with an adjusting mechanism 5; wherein, the adjusting mechanism 5 includes a mounting plate 51 fixedly connected to the bottom end of the electric push rod 4, on one side of the mounting plate 51, a rotating shaft 52 is rotatably connected, one end of the rotating shaft 52 penetrates through the mounting plate 51 and is rotatably connected to a large gear 53, the other end of the large gear 53 is fixedly connected to a fixing rod 54, on the lower end surface of the fixing rod 54, a polishing machine 55 is installed, on the surface of the fixing rod 54, a mounting rod 56 is fixedly connected, the other end of the mounting rod 56 is fixedly connected to a ring 57, on the inner wall of the ring 57, a round rod 58 is rotatably connected, one end of the round rod 58 is fixedly connected to a small gear 59, and the small gear 59 is meshed with the large gear 53. Under the action of the gear ratio between the large gear 53 and the small gear 59, when the small gear 59 drives the large gear 53 to rotate, the large gear 53 will drive the polishing machine 55 to have a small angular change.

[0025] The polishing machine 55 includes a connecting plate, a second motor, and a grinding block. Among them, the top end of the connecting plate is fixedly connected to the surface of the fixing rod 54, and the second motor is fixedly connected to the connecting plate. When it is necessary to polish a workpiece, the second motor is started through the controller to drive the grinding block to rotate to perform the grinding operation.

[0026] As Figure 3 、 Figure 4 and Figure 5 shown, the adjusting mechanism 5 further includes a round plate 510 slidably connected to the inner wall of the round rod 58, one end of the round plate 510 is hinged to a connecting rod 511, on the inner wall of the round rod 58, a clamping rod 512 is slidably connected, the other end of the connecting rod 511 is hinged to one end of the clamping rod 512, between the other end of the round plate 510 and the inner wall of the round rod 58, a spring 513 is fixedly connected, on the inner wall of the ring 57, a plurality of annularly distributed clamping holes 514 are opened, the other end of the round plate 510 is fixedly connected to a pull rod 515, and the other end of the pull rod 515 penetrates through the spring 513 and the round rod 58 on one side. On one side of the mounting plate 51, a first motor 516 is fixedly connected, and the other end of the rotating shaft 52 is fixedly connected to the output shaft of the first motor 516. The other end of the clamping rod 512 is bent into a spherical shape.

[0027] The shape of the card hole 514 matches that of the card rod 512. In the initial state of the device, the spring 513 is in a released state. The card rod 512 is clamped with one of the card holes 514 under the action of the spring 513. When the angle of the polishing machine 55 needs to be adjusted, the controller starts the first motor 516 to drive the rotating shaft 52 to rotate, and drives the mounting rod 56, the ring 57, and the round rod 58 to rotate through the rotating shaft 52, thereby driving the small gear 59 and the large gear 53 to rotate with the center of the rotating shaft 52 as the rotation center point. When the large gear 53 rotates, it will drive the fixed rod 54 to rotate, thereby driving the polishing machine 55 to rotate for preliminary angle adjustment. After the preliminary adjustment, the staff pulls the pull rod 515 to move away from the round rod 58. At this time, the pull rod 515 will drive the round plate 510 to move synchronously, the spring 513 is compressed, and the round plate 510 will drive the card rod 512 away from the card hole 514 through the connecting rod 511, thereby releasing the clamping. At this time, when the staff pulls the pull rod 515 and rotates the pull rod 515 at the same time, at this time, under the action of the round plate 510, the connecting rod 511, and the card rod 512, the round rod 58 will be driven to rotate synchronously, and the small gear 59 will be driven to rotate, thereby driving the large gear 53 to rotate synchronously, so as to precisely adjust the angle of the polishing machine 55. After rotating to the appropriate position, the pull rod 515 is released, the spring 513 is released, and the card rod 512 will enter the corresponding card hole 514 under the action of the spring 513.

[0028] As Figure 5 shown, a limiting rod 518 is fixedly connected to the inner wall of the round rod 58, and the inner wall of the round plate 510 is slidably connected to the surface of the limiting rod 518. When the pull rod 515 is rotated to drive the round plate 510 to rotate, the round plate 510 will drive the limiting rod 518 to rotate synchronously, thereby driving the round rod 58 to rotate.

[0029] As Figure 5 shown, a groove 519 is formed on the surface of the round rod 58, and the other end of the card rod 512 penetrates into the groove 519. A limiting block 517 is fixedly connected to the inner wall of the round rod 58.

[0030] When the clamping of the card rod 512 with the card hole 514 is released by pulling the pull rod 515, when the other end of the round plate 510 contacts one side of the limiting block 517, the round plate 510 cannot move further. At this time, the end of the card rod 512 will contract in the groove 519 and will not contact the inner wall of the ring 57, so as not to affect the rotation of the round rod 58.

[0031] When the utility model is in use, the workpiece is placed on the top of the base 1 and fixed by two fixing plates 2. When adjusting the angle of the polishing machine 55 according to requirements, the controller starts the first motor 516 to drive the rotating shaft 52 to rotate, and the rotating shaft 52 drives the mounting rod 56, the ring 57 and the round rod 58 to rotate, so as to drive the small gear 59 and the large gear 53 to rotate with the center of the rotating shaft 52 as the rotation center point. When the large gear 53 rotates, it will drive the fixed rod 54 to rotate, so as to drive the polishing machine 55 to rotate for preliminary angle adjustment. After the preliminary adjustment, the staff pulls the pull rod 515 to move away from the round rod 58. At this time, the pull rod 515 will drive the round plate 510 to move synchronously, the spring 513 is compressed, and the round plate 510 will drive the clamping rod 512 away from the clamping hole 514 through the connecting rod 511. When the other end of the round plate 510 contacts one side of the limiting block 517, the round plate 510 cannot move any further. At this time, the end of the clamping rod 512 will shrink in the groove 519, so as to release the clamping connection. At this time, when the staff pulls the pull rod 515 and rotates the pull rod 515 at the same time, at this time, under the action of the round plate 510, the limiting rod 518, the connecting rod 511 and the clamping rod 512, the round rod 58 will be driven to rotate synchronously, and the small gear 59 will be driven to rotate with the center of the round rod 58 as the rotation center point, so as to drive the large gear 53 to rotate synchronously, so as to accurately adjust the angle of the polishing machine 55. After the adjustment is completed, the controller starts the electric push rod 4 to push the polishing machine 55 to a suitable height and drives the polishing machine 55 to run to perform the polishing operation.

[0032] It should be noted that in the above description, the electric push rod 4, the first motor 516 and the second motor are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the electric push rod 4, the first motor 516 and the second motor can be the built-in power supply or the mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0033] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard this specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
