Description

Technical Field

[0001] This utility model relates to the field of support shaft polishing technology, specifically, to a support shaft grinding and polishing device. Background Technology

[0002] In the field of machining, the surface grinding and polishing quality of the support shaft directly affects its performance.

[0003] Existing polishing and grinding equipment mostly uses fixed pressure grinding, which cannot adapt to workpiece size deviations or material hardness changes, and may cause over-grinding or under-grinding. This is especially unfavorable for the processing of high-precision shaft parts, and lacks a real-time feedback adjustment mechanism. When changing production models, tooling needs to be manually adjusted frequently, resulting in low production efficiency.

[0004] Therefore, there is an urgent need for a grinding device that can sense grinding pressure, automatically adjust its position, and adapt to different workpieces in order to improve product quality and production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a support shaft grinding and polishing device that can sense grinding pressure, automatically adjust position and adapt to different workpieces, so as to improve product quality and production efficiency.

[0006] A support shaft grinding and polishing device includes a main support, a feeding mechanism, and a grinding mechanism. The feeding mechanism is mounted on the main support, and the grinding mechanism is mounted on the main support near the feeding mechanism. The grinding mechanism includes a grinding machine and an adjustment component. The grinding machine is mounted on the movable end of the adjustment component, and the fixed end of the adjustment component is mounted on the main support. The grinding machine is equipped with a pressure sensor and a main controller. The pressure sensor is electrically connected to the main controller and the adjustment component. The adjustment component is used to adjust the position of the grinding machine.

[0007] As a further limitation of this technical solution, the adjustment component includes a threaded rod and a drive motor. The grinder is slidably mounted on the main support. The threaded rod is threadedly connected to the grinder. The output shaft of the drive motor is coaxially and fixedly connected to one end of the threaded rod. The drive motor is electrically connected to the main controller.

[0008] As a further limitation of this technical solution, the feeding mechanism includes a limiting component, which includes a support shaft placement groove, a slide, a bolt, and a nut. The slide is fixedly mounted on the main support, and a fixing plate is fixedly mounted at the bottom of the support shaft placement groove. A through hole is provided on the fixing plate, and one end of the bolt passes through the slide and the through hole and is threadedly connected to the nut.

[0009] As a further limitation of this technical solution, the limiting component also includes an electric push rod, a baffle, and a roller. The housing of the electric push rod is fixedly mounted on the support shaft placement groove, the baffle is fixedly mounted on the telescopic rod of the electric push rod, and the roller is rotatably mounted on the baffle.

[0010] As a further limitation of this technical solution, it also includes a receiving assembly, which includes a receiving plate. The receiving plate is detachably mounted on the main support and is located on the side away from the support shaft placement groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are:

[0012] 1. The grinding force is sensed in real time by a pressure sensor and the signal is fed back to the main controller. The main controller controls the drive motor to rotate the threaded rod, which in turn moves the grinder and controls the pressure between the grinding head and the support shaft to be ground, thereby improving the grinding effect.

[0013] 2. A limiting component is set up to make the feeding and transmission process of the support shaft more stable and avoid damage to the support shaft by the grinding head due to tilting during feeding. Attached Figure Description

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0020] A support shaft grinding and polishing device includes a main support 100, a feeding mechanism 400, and a grinding mechanism 300. The feeding mechanism 400 is disposed on the main support 100, and the grinding mechanism 300 is disposed on the main support 100 near the feeding mechanism 400. The grinding mechanism 300 includes a grinding machine 320 and an adjustment component. The grinding machine 320 is disposed at the movable end of the adjustment component, and the fixed end of the adjustment component is disposed on the main support 100. A pressure sensor and a main controller are disposed on the grinding machine 320. The pressure sensor is electrically connected to the main controller and the adjustment component. The adjustment component is used to adjust the position of the grinding machine 320.

[0021] Specifically, the adjustment component can move the grinder 320 to make the grinding wheel contact the support shaft to be ground. When the grinding head contacts the support shaft, the pressure sensor senses the pressure and transmits the pressure value to the main controller. The main controller further adjusts the position of the grinder 320 by controlling the adjustment component until the pressure sensor reaches the set value.

[0022] The adjustment assembly includes a threaded rod 330 and a drive motor 310. The grinder 320 is slidably mounted on the main support 100. The threaded rod 330 is threadedly connected to the grinder 320. The output shaft of the drive motor 310 is coaxially and fixedly connected to one end of the threaded rod 330. The drive motor 310 is electrically connected to the main controller.

[0023] Specifically, the main controller drives the output shaft of the drive motor 310 to rotate, which in turn drives the threaded rod 330 to rotate. The threaded rod 330 drives the grinder 320 to slide on the main support 100. In this embodiment, a T-shaped guide rod is fixedly installed on the main support 100, and a T-shaped through groove is provided at the bottom of the grinder 320. The grinder 320 is slidably installed on the T-shaped guide rod through the T-shaped through groove.

[0024] The feeding mechanism 400 includes a limiting component, which includes a support shaft placement groove 440, a slide 460, a bolt 470, and a nut 480. The slide 460 is fixedly mounted on the main support 100. A fixing plate 450 is fixedly mounted at the bottom of the support shaft placement groove 440. The fixing plate 450 has a through hole. One end of the bolt 470 passes through the slide 460 and the through hole and is threadedly connected to the nut 480.

[0025] Specifically, the support shaft placement groove 440 is V-shaped. The support shaft is placed in the support shaft placement groove 440. The height of the support shaft placement groove 440 is adjusted according to the diameter of the support shaft. After the height is adjusted, the bolt 470 is passed through the through hole on the slide 460 and the fixing plate 450, and the nut 480 is tightened onto the bolt 470 to achieve mutual locking between the fixing plate 450 and the slide 460.

[0026] The limiting assembly also includes an electric push rod 410, a baffle 420, and a roller 430. The housing of the electric push rod 410 is fixedly mounted on the support shaft placement groove 440. The baffle 420 is fixedly mounted on the telescopic rod of the electric push rod 410. The roller 430 is rotatably mounted on the baffle 420.

[0027] Specifically, after the support shaft is installed, the electric push rod 410 is activated. The telescopic rod of the electric push rod 410 retracts, causing the baffle 420 and roller 430 to descend until the roller 430 contacts the support shaft. At this point, the electric push rod 410 stops. The position of the support shaft is further restricted, and it can only move along the length of the support shaft placement groove 440. When moving, the roller 430 rolls along with it, which reduces friction.

[0028] It also includes a receiving assembly, which includes a receiving plate 200. The receiving plate 200 is detachably mounted on the main support 100. The receiving plate 200 is located on the side away from the support shaft placement groove 440. After the support shaft is ground, it moves toward the receiving assembly and falls onto the receiving plate 200 without manual assistance, saving manpower.

[0029] The working process of this utility model is as follows:

[0030] The support shaft is placed in the V-shaped support shaft placement groove 440 of the feeding mechanism 400. The height of the placement groove is adjusted and locked in the slide groove 460 using bolts 470 and nuts 480 according to its diameter. The electric push rod 410 is activated, causing the baffle 420 and roller 430 to descend until they contact the support shaft, limiting its movement along the length of the placement groove (the roller 430 rolls to reduce friction). The drive motor 310 drives the threaded rod 330 to rotate, causing the grinder 320 to move along the T-shaped groove. When the guide rod slides and the grinding wheel contacts the support shaft, the pressure sensor transmits the pressure value to the main controller. The main controller controls the drive motor 310 to fine-tune the rotation angle of the threaded rod 330 until the pressure reaches the preset value. The grinding machine 320 grinds and polishes the support shaft. The feeding mechanism 400 drives the workpiece to feed (the roller 430 assists in conveying). After completion, the workpiece automatically falls onto the detachable receiving plate 200 on the other side of the main support 100 for unloading. When changing the workpiece specifications, the height of the placement slot is adjusted or the pressure parameters are reset by the main controller, and the position of the grinding machine 320 is adjusted by the drive motor 310 to achieve the change of type.

[0031] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
