Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically to an electric grinding frame for irregularly shaped parts. Background Technology

[0002] Currently, the grinding of irregularly shaped parts usually involves placing the parts directly on the ground or a grinding platform, and manually using a handheld grinder to complete the grinding. This grinding method, especially for grinding the inner walls of irregularly shaped parts that are close to bowls, requires constantly turning the parts over to adjust the grinding area, resulting in low grinding efficiency and a rather cumbersome grinding process. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides an electric grinding frame for irregularly shaped parts.

[0004] The technical solution of this utility model is as follows:

[0005] An electric grinding frame for irregularly shaped parts includes a base plate and a support device and a grinding device disposed thereon. The support device is configured to support and fix the irregularly shaped parts, and the grinding device enables manual grinding of the irregularly shaped parts on the support device.

[0006] As the core technical concept of this utility model, the supporting device includes a horizontally arranged turntable that can be driven to rotate by a rotary motor. The upper side of the turntable is provided with a support member capable of supporting and fixing irregularly shaped parts. The rotation of the rotary motor drives the turntable to rotate, thereby causing the irregularly shaped parts on it to rotate. A vertical support rod is also provided on the base plate, and a hinge device is provided at the upper end of the support rod. The grinding device includes a grinding bracket connected to the hinge device on one side, which is configured to rotate around a vertical axis and float up and down on the side opposite to the hinge device. A grinding motor is located in the middle of the grinding bracket. Based on this structure, by manually holding the grinding stand away from the hinge device, the side of the grinding stand away from the hinge device can be lifted. By rotating around the vertical axis under the action of the hinge device, the grinding motor can be moved to the position of the irregular part. Finally, in conjunction with the action of the grinding motor, the grinding work of the irregular part is completed during the rotation of the irregular part. The irregular part only needs to be fixed once to complete the overall grinding work, which improves the grinding efficiency. At the same time, compared with the method of grinding with a hand-held grinder, the method of grinding with a hand-held grinding stand is more labor-saving and ensures the grinding effect.

[0007] As described above, in a preferred embodiment of an electric grinding frame for irregularly shaped parts, multiple support members are arranged in a circumferential array around the axis of the turntable to facilitate the fixing of the irregularly shaped parts, and the irregularly shaped parts are configured to be supported and fixed between the multiple support members.

[0008] As a further preferred embodiment, the support member includes a fixed block fixedly disposed on the upper side of the turntable, and an adjusting block that can adjust the distance from the turntable axis is slidably disposed on the fixed block. This arrangement enables the support device to be used for supporting and fixing parts of different specifications and shapes, thereby improving the applicability of the grinding frame.

[0009] Preferably, in order to facilitate the adjustment and positioning of the adjusting block, the fixing block is provided with a sliding groove, the adjusting block is slidably connected to the sliding groove, and is provided with a fastening bolt that can abut against the bottom of the sliding groove.

[0010] As described above, the electric grinding frame for irregularly shaped parts includes a rotating base rotatably mounted on the upper end of a support rod with a vertical axis of rotation. An adjusting base with a horizontal axis of rotation is hinged to the rotating base. The grinding bracket is connected to the adjusting base, allowing the grinding bracket to rotate around the horizontal axis via the adjusting base, thus enabling the side away from the hinge device to be lifted smoothly. Simultaneously, the grinding bracket can rotate around the vertical axis via the rotating base, allowing the grinding motor to be smoothly moved to the position of the irregularly shaped part to complete the grinding work.

[0011] As described above, in a preferred embodiment of the electric grinding stand for irregularly shaped parts, in order to facilitate manual hand-held grinding of irregularly shaped parts, the grinding stand has a forked structure on the side away from the hinge device, that is, the grinding stand is Y-shaped or h-shaped as a whole.

[0012] As a further preferred embodiment, the lower side of the turntable is coaxial with and has a fixed plate at a gap, so that when the irregular part is being fixed, the turntable can be fixed by inserting a blocking object into the gap between the fixed plate and the turntable, thereby facilitating the fixing of the irregular part.

[0013] Preferably, to prevent the grinding bracket from falling to the ground or base plate due to lack of support when it is moved to the outside of the support device after grinding, and to ensure that the grinding work of the irregular part can be carried out more conveniently next time, the upper side of the base plate is also provided with a support rod that can support the grinding bracket.

[0014] The beneficial effects of this utility model are as follows: This utility model is an electric grinding frame for irregularly shaped parts. The rotation of the motor can drive the turntable to rotate, thereby driving the irregularly shaped parts on it to rotate. By manually holding the grinding frame away from the hinge device, the side of the grinding frame away from the hinge device can be lifted. Through the rotation around the vertical axis under the action of the hinge device, the grinding motor can be moved to the position of the irregularly shaped part. Finally, in conjunction with the action of the grinding motor, the grinding work of the irregularly shaped part is completed during the rotation of the irregularly shaped part. The irregularly shaped part only needs to be fixed once to complete the overall grinding work, which improves the grinding efficiency. At the same time, compared with the method of grinding with a hand-held grinding machine, the method of grinding with a hand-held grinding frame is more labor-saving and ensures the grinding effect.

The support device 2 is configured to support and fix irregularly shaped parts, and the grinding device 5 enables manual grinding of irregularly shaped parts on the support device 2. The structure of the grinding frame (the above-mentioned electric grinding frame for irregularly shaped parts) will be described in detail below with reference to the accompanying drawings.

[0027] In this embodiment, combined with Figure 3 The supporting device 2 includes a horizontally arranged turntable 25 that can be driven to rotate by a rotating motor 23. The upper side of the turntable 25 is provided with a support member 26 that can support and fix the irregular part. The rotation of the rotating motor 23 can drive the turntable 25 to rotate, thereby driving the irregular part on it to rotate.

[0028] Specifically, the supporting device 2 includes a bracket 21 vertically arranged on the upper side of the base plate 1. A reducer 22 is provided on the lower part of one side of the bracket 21. The rotating motor 23 is driven to one side of the reducer 22. A drive shaft 24 is vertically arranged on the upper side of the reducer. The turntable 25 is connected to the upper end of the shaft. The lower end of the shaft is driven to the reducer 22. By rotating the rotating motor 23, power can be transmitted to the drive shaft 24 through the reducer 22, thereby driving the turntable 25 to rotate.

[0029] In a preferred embodiment, a fixed plate 27 is coaxially and fixed with a gap on the lower side of the turntable 25. The fixed plate 27 is fixed to the upper side of the bracket 21. The drive shaft 24 passes through the middle of the fixed plate 27. When the irregular part is fixed, the turntable 25 can be fixed by inserting a blocking object into the gap between the fixed plate 27 and the turntable 25, thereby facilitating the fixing of the irregular part.

[0030] In this embodiment, combined with Figure 4 In a preferred embodiment, to facilitate the fixing of irregularly shaped parts, multiple support members 26 are arranged in a circumferential array around the axis of the turntable 25, and the irregularly shaped parts are configured to be supported and fixed among multiple support members 26.

[0031] As a further preferred embodiment, the support member 26 includes a fixing block 261 fixedly disposed on the upper side of the turntable 25. The fixing block 261 is slidably provided with an adjusting block 262 that can adjust the distance from the axis of the turntable 25. With this arrangement, the support device 2 can be used for supporting and fixing parts of different specifications and shapes, thus improving the applicability of the grinding frame.

[0032] Preferably, to facilitate the adjustment and positioning of the adjusting block 262, the fixing block 261 is provided with a sliding groove, the adjusting block 262 is slidably connected to the sliding groove, and is provided with a fastening bolt 263 that can abut against the bottom of the sliding groove. Specifically, the adjusting block 262 includes an L-shaped structure composed of a horizontal section and a vertical section, wherein the horizontal section is slidably connected to the sliding groove, and the end away from the vertical section faces the center of the turntable 25, the lower end of the vertical section is connected to the horizontal section, and the upper end is vertically upward, the fastening bolt 263 is provided on the horizontal section, and the irregular part is configured to be supported and fixed between the vertical sections of several adjusting blocks 262.

Based on this structure, by manually holding the grinding bracket 51 on the side away from the hinge device 4, the side of the grinding bracket 51 away from the hinge device 4 can be lifted. By rotating around the vertical axis under the action of the hinge device 4, the grinding motor 52 can be moved to the position of the irregular part. Finally, in conjunction with the action of the grinding motor 52, the grinding work of the irregular part is completed during the rotation of the irregular part. The irregular part only needs to be fixed once to complete the overall grinding work, which improves the grinding efficiency. At the same time, compared with the method of grinding by hand holding a grinding machine, the method of grinding by lifting the grinding bracket 51 is more labor-saving and ensures the grinding effect.
