Description

Technical Field

[0001] This utility model relates to the field of grinding wheel support technology, and in particular to an angle-adjustable grinding wheel support. Background Technology

[0002] In existing grinding operations, traditional grinding wheel supports are usually fixed at a single angle, which makes it difficult to meet the diverse grinding angle requirements of different shapes and processing techniques.

[0003] In actual production and processing scenarios, when encountering complex workpieces, such as parts with irregular curved surfaces, multi-angled edges, or special shapes, the drawbacks of traditional fixed-angle grinding wheel supports become apparent. Because their angle cannot be flexibly adjusted according to the specific characteristics of the workpiece, the contact method between the grinding wheel and the workpiece is not ideal, which easily leads to problems such as uneven grinding and poor allowance control during the grinding process. This directly results in a significant reduction in processing accuracy and makes it difficult for product quality to reach high standards.

[0004] Furthermore, this limitation means that when facing diverse processing tasks, enterprises need to equip themselves with a variety of specific equipment. Not only is the equipment versatility and adaptability poor, but the increased equipment procurement costs and the extended processing time due to frequent equipment replacements also seriously affect the enterprise's production efficiency and market competitiveness.

[0005] Therefore, this utility model proposes an angle-adjustable grinding wheel bracket. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angle-adjustable grinding wheel support.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an angle-adjustable grinding wheel support, comprising:

[0008] The grinding wheel assembly consists of a drive mechanism and mounting covers on both sides. A grinding wheel disc is rotatably connected to each of the two mounting covers, and a protective cover is provided on the side of each mounting cover that is far apart from each other.

[0009] Adjustable bracket assembly; The adjustable bracket assembly consists of a mounting base located at the bottom of the drive mechanism, a first bracket arm, a second bracket arm, and a rotating base. A connecting shaft is provided between the first bracket arm and the second bracket arm. A first electric push rod is provided between the rotating base and the second bracket arm. A second electric push rod is provided between the second bracket arm and the first bracket arm. A third electric push rod is provided between the first bracket arm and the mounting base.

[0010] A rotary mounting assembly, comprising a mounting bracket and a mounting plate disposed at the bottom of a rotary base, wherein a servo motor connected to the rotary base is disposed within the mounting bracket, and ball bearings are disposed between the rotary base and the mounting bracket.

[0011] In a preferred embodiment, the mounting bracket and the rotating seat are both provided with sliding grooves on their respective sides, and the ball bearings are slidably connected within the ball bearings.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the ball bearings are limited by the sliding groove, preventing them from falling out and separating from the mounting bracket and rotating seat during use.

[0013] In a preferred embodiment, the mounting plate has mounting holes arranged in a ring, and the included angle between two adjacent mounting holes is equal.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the mounting hole is used to install and fix the mounting plate. In use, the mounting plate is fixed to the ground by the mounting bolt, thereby improving the stability of the device in use.

[0015] In a preferred embodiment, the output end of the servo motor passes through the mounting bracket and is connected to the rotary base.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the servo motor, power is provided for the rotation of the rotary table, so that the rotary table can be rotated to a designated position for grinding work according to the actual situation during use, thereby improving the application range of the device.

[0017] In a preferred embodiment, the balls are arranged in a ring shape, and the diameter of the balls is adapted to the diameter of the sliding groove.

[0018] The beneficial effects of adopting the above-mentioned further solution are: under the action of the ball bearings, auxiliary support is provided between the rotary seat and the mounting frame. Since a certain gap is reserved between the rotary seat and the mounting frame, the design of this gap is to reduce the friction between the rotary seat and the mounting frame. However, when the center of gravity of the grinding wheel assembly shifts excessively during use, the rotary seat will tilt on the mounting frame, which may lead to the breakage of the output shaft of the servo motor.

[0019] In a preferred embodiment, the two ends of the first electric push rod are rotatably connected to the rotating base and the second support arm, the two ends of the second electric push rod are rotatably connected to the first support arm and the second support arm, and the two ends of the third electric push rod are rotatably connected to the first support arm and the mounting base.

[0020] The beneficial effects of adopting the above-mentioned further solution are as follows: the first electric push rod is used to adjust the angle between the second support arm and the rotating seat, thereby changing the working angle of the grinding wheel assembly; further, under the action of the second electric push rod, the included angle between the first support arm and the second support arm is adjusted, thereby further increasing the working range of the grinding wheel assembly; and under the action of the third electric push rod, the angle between the mounting seat and the first support arm is adjusted, thereby changing the tilt angle of the grinding wheel assembly during operation.

[0021] In a preferred embodiment, the output end of the drive mechanism is connected to the grinding wheel after passing through the mounting cover.

[0022] The beneficial effects of adopting the above-mentioned further solution are: the driving mechanism provides power for the rotation of the grinding wheel, and the driving mechanism drives the grinding wheel to rotate to achieve the grinding effect. Furthermore, the mounting cover and protective cover protect the grinding wheel and prevent it from being damaged during use.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. In this utility model, by adjusting the setting of the support assembly, the grinding wheel assembly can be angled during use. First, under the action of the servo motor, the rotating seat can be rotated for machining, increasing the machining range of the grinding wheel assembly. Furthermore, under the action of the first electric push rod, the second support arm is driven to adjust its angle, and the second electric push rod drives the first support arm to adjust its angle, further increasing the machining range of the grinding wheel assembly. And under the action of the third electric push rod, the mounting seat is driven to adjust its tilt angle during machining, thereby reducing the machining dead angle of the device.

[0025] 2. In this utility model, the ball bearings provide auxiliary support for the rotating seat and the mounting frame. Since a certain gap is reserved between the rotating seat and the mounting frame, the design of this gap is to reduce the friction between the rotating seat and the mounting frame. However, when the center of gravity of the grinding wheel assembly shifts excessively during use, the rotating seat will tilt on the mounting frame, which may lead to the breakage of the output shaft of the servo motor.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: an angle-adjustable grinding wheel holder, comprising:

[0036] The grinding wheel assembly 1 consists of a drive mechanism 11 and mounting covers 12 on both sides. A grinding wheel disk 14 is rotatably connected to each of the two mounting covers 12, and a protective cover 13 is provided on the side of the two mounting covers 12 that is far apart from each other.

[0037] Adjustable bracket assembly 2; The adjustable bracket assembly 2 consists of a mounting base 23 located at the bottom of the drive mechanism 11, a first bracket arm 21, a second bracket arm 22, and a rotating base 24. A connecting shaft 28 is provided between the first bracket arm 21 and the second bracket arm 22. A first electric push rod 25 is provided between the rotating base 24 and the second bracket arm 22. A second electric push rod 26 is provided between the second bracket arm 22 and the first bracket arm 21. A third electric push rod 27 is provided between the first bracket arm 21 and the mounting base 23.

[0038] The rotating mounting assembly 3 consists of a mounting bracket 32 ​​and a mounting plate 31 located at the bottom of the rotating base 24. A servo motor 33 connected to the rotating base 24 is housed within the mounting bracket 32. Ball bearings 322 are positioned between the rotating base 24 and the mounting bracket 32. The output end of the servo motor 33 passes through the mounting bracket 32 ​​and connects to the rotating base 24. The two ends of the first electric push rod 25 are rotatably connected to the rotating base 24 and the second support arm 22, respectively. The two ends of the second electric push rod 26 are rotatably connected to the first support arm 21 and the second support arm 22, respectively. The two ends of the third electric push rod 27 are rotatably connected to the first support arm 21 and the mounting base 23, respectively. The drive mechanism 11... The output end of the device passes through the mounting cover 12 and connects to the grinding wheel 14. By adjusting the setting of the bracket assembly 2, the grinding wheel assembly 1 can be angled during use. First, under the action of the servo motor 33, the rotating seat 24 can be rotated for machining, thereby increasing the machining range of the grinding wheel assembly 1. Furthermore, under the action of the first electric push rod 25, the second support arm 22 is driven to adjust its angle, and the second electric push rod 26 drives the first support arm 21 to adjust its angle, thereby further increasing the machining range of the grinding wheel assembly 1. And under the action of the third electric push rod 27, the mounting seat 23 is driven to adjust its tilt angle during machining, thereby reducing the machining dead angle of the device.

[0039] Furthermore, such as Figure 2 - Figure 4 As shown: Sliding grooves 321 are provided on the side of the mounting bracket 32 ​​and the rotating seat 24 that are close to each other. The ball bearing 322 is slidably connected in the ball bearing 322. The mounting plate 31 is provided with mounting holes 311. The mounting holes 311 are distributed in a ring and the included angle between two adjacent mounting holes 311 is equal. Under the action of the ball bearing 322, auxiliary support is provided between the rotating seat 24 and the mounting bracket 32. Since a certain gap is reserved between the rotating seat 24 and the mounting bracket 32, the design of this gap is to reduce the friction between the rotating seat 24 and the mounting bracket 32. However, when the center of gravity of the grinding wheel assembly 1 shifts excessively during use, the rotating seat 24 will tilt on the mounting bracket 32, which may seriously lead to the breakage of the output shaft of the servo motor 33.

[0040] The above solutions also have the problem of the device tilting and overturning due to the shift in the center of gravity, such as... Figure 4 As shown: In this scheme, mounting plate 31 is provided with mounting holes 311. The mounting holes 311 are arranged in a ring, and the included angle between two adjacent mounting holes 311 is equal. The function of the mounting holes 311 is to install and fix the mounting plate 31. In use, the mounting plate 31 is fixed to the ground by mounting bolts, thereby improving the stability of the device in use.

[0041] Working principle:

[0042] like Figure 1-4 As shown, the device is placed in the designated position. Then, the mounting plate 31 is connected and fixed to the mounting surface by inserting the mounting bolt into the mounting hole 311. After fixing, the drive mechanism 11 is turned on to drive the grinding wheel 14 to rotate for material grinding. During the grinding process, the servo motor 33 can be controlled to drive the rotating seat 24 to rotate, so that the grinding angle of the grinding wheel assembly 1 is changed. Furthermore, under the action of the first electric push rod 25, the second electric push rod 26 and the third electric push rod 27, the included angles between the rotating seat 24, the second support arm 22, the first support arm 21 and the mounting seat 23 are adjusted respectively, so that the grinding wheel assembly 1 is adjusted to a suitable working angle.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
